In addition to the normal chair function, the present invention is a user seated on a seat such as a twisting motion , a circular motion that swivels around the waist or in an 8-shaped shape , or a swinging motion that moves linearly back and forth or diagonally. The present invention relates to a chair capable of gymnastics provided with a function of varying an elastic restoring force (elastic restoring force / stability) that works against various movements and works against the direction of movement, and a function of adjusting.

  Conventionally, in a chair provided with an exercise function, a “fitness chair” described in PR No. 3135028 or a “chair used to strengthen the waist” described in JP 2009-540871 PR or "Chair-type exercise equipment" described in Japanese Patent Application Laid-Open No. 2008-149029 is introduced.

The main structure of the fitness chair includes a leg portion, a columnar chair column that is erected on the upper portion of the leg portion, and a bearing that is rotatably fitted on the upper portion of the chair column and is built in both the upper and lower sides. One end on the side for fixing the cylindrical rotating part to the chair post is provided, and one end on the side for fixing the rotating part to the chair post is rotatably fitted on the upper part of the chair post.
A crosspiece is horizontally provided below one end on the side fixed to the chair post, and the other end of the cylindrical rotating part is provided above the end of the crosspiece.
Moreover, one end of the side which fixes the columnar adjustment component inserted in the other end of this rotary component to the rotary component is rotatably inserted in the upper part of the other end of the said rotary component.
Further, a crosspiece is horizontally provided above one end on the side where the adjustment component is fixed to the rotary component, and the rotary component having a built-in bearing on both the upper and lower sides of the crosspiece is used as a chair post. The other end of the cylindrical adjustment component having a similar structure is attached to one end of the fixing side.
A cylindrical projection suspended below the cylindrical seating support column is inserted from above into the inner ring of the bearing, and the columnar support suspended below the seating portion is the seating. It is connected to the upper part of the column.

Further, the main structure of the chair used for strengthening the waist consists of a circular plate with handles recessed on the left and right sides, a flat upper end portion suspended from the back surface of the circular plate, and the upper end. A sheet that is formed in a cylindrical shape that surrounds the periphery of the unit and is suspended below the circular plate, and a transverse that is loosely fitted in the receptacle that supports the sheet from below. A cylindrical connection part with a roughly bowl shaped bowl-shaped container installed at the top, a coiled spring connecting the upper part of the container and the upper end part and a narrow upper part, and engagement below the connection part The support portion is made of.
In this configuration, the lower side of the upper end portion and the upper portion of the spring are engaged, and the upper side of the cylindrical connection portion and the lower portion of the spring are engaged. It is attached to the upper part of the said connection part in the state movable to the circumference and the left-right rotation direction via.

Noto 3135028 Special table 2009-540871 JP 2008-149029 PR

In the fitness chair described in Patent Document 1, the rotating component and the adjusting component freely rotate on different axes on the horizontal line. Therefore, when the user sits down on the seating part and puts both feet on the ground, the user performs a twisting movement that repeats torsion of the hips from the buttocks and a circular movement that draws a circle on different axes on the horizon. Twist exercise can be performed.
However, the seat support column, the chair column, the rotating component, or the adjusting component is provided with a structure in which any one of these is provided at an angle that is inclined outward in the circumferential direction, or the inclination angle is variable (changed). Neither is it provided with a structure for moving the seating portion up and down during a circular motion.
Therefore, in such a structure, it is originally impossible to perform a three-dimensional turning motion that is shaken so that the upper body is thrown out to the outside in the circumferential direction.
In addition, it does not have a structure to apply stress (reaction force / drag) against the user's direction of movement during circular motion and twist motion. Therefore, it is difficult to say that it is an exercise device suitable for training the rectus abdominis and external oblique or latissimus dorsi muscles, especially when strong training of the rectus abdominis and the external obliques is desired, It is necessary to consciously perform the tilting action so that the body is thrown in the circumferential direction.
In addition, since a structure that generates an external load on the user's body during circular and twist exercises is not provided, especially the straight abdominal and external oblique muscles can be efficiently trained and strengthened. It is hard to say that it is a tool.

In the chair used for strengthening the waist described in Patent Document 2, a twist exercise that twists the hip and abdomen around the hip in the posture in which the user is seated on the seat or the waist around the body while tilting the body outward in the circumferential direction It is possible to perform a circular motion that draws a narrow ellipse or a narrow figure of 8 around the center. At this time, the elastic restoring force of the spring acts against the user's action, so it is suitable for training the rectus abdominis muscle and the external oblique muscle.
However, there is a lack of a structure for urging or depressing by changing or adjusting the elastic restoring force that resists deformation of the spring.
For example, it is assumed that a heavy user sits on the seat and performs a twisting motion or a rotational motion.
In this case, from the point of lacking a structure for urging the elastic restoring force acting on the spring, a malfunction as an exercise device due to excessive flatness (deformation) of the spring is assumed.
At the same time, in the worst case, the spring is excessively flat, and the upper end of the container and the back surface of the sheet are in contact with each other, so that the sheet does not follow the movement of the user and does not serve as an exercise device. Concerns arise.
In the first place, users with various weights, twisting motions, turning motions (circular motions), or linear motions from the point of lack of a structure for energizing or reducing the elastic restoring force of the spring against the user's motions. It is an exercise device that is unsuitable for users who want to change or adjust the exercise intensity as desired.

As an example, when muscle relaxation exercises are performed in a state of weakness by reducing the brightness of the light before going to bed, the sleep quality can be improved by the relaxation effect obtained from moderate fatigue of the body and relaxation of mental tension. Are known.
However, in the chair used for strengthening the waist, the elastic restoring force acting on the spring engaged between the lower side of the upper end portion and the upper side of the cylindrical connecting portion is variable or adjusted from the outside of the receptacle. It lacks the structure to be energized or de-energized.
Therefore, it is impossible to adjust the elastic restoring force of the spring that works during exercise according to conditions such as weights and physical abilities of various users or each situation.

On the other hand, in a posture in which a user such as an elderly person, a woman or a handicapped who is weak in force sits on the seat in a state where a spring having the same shape and the same size and high elasticity is built in the container In the case of performing a muscle relaxation motion such as a swing motion that moves linearly in the direction, it is structurally impossible to adjust the elastic restoring force acting on the spring from the outside of the receptacle in advance and reduce it.
On the other hand, when a user who has a heavy weight or a user who desires strong muscle training performs a twisting motion or a rotational motion, the elastic restoring force acting on the spring incorporated in the container may be adjusted and biased. Structurally impossible.
Therefore, when a user who has a heavy weight or a user who desires strong muscle training sits on the seat and performs a twisting motion or a circular motion, a situation where the elastic restoring force against the deformation of the spring is insufficient is also assumed. The
Therefore, it is difficult to say that it is an exercise device for everyone, the starting point when the seat is in operation, the upper end of the spring engaged below the upper end corresponding to the action point, and the upper side of the cylindrical connecting portion The sheet is tilted when the outer wall of the container and the inner wall of the receptacle are in contact with each other at a point where the distance from the lower end of the spring engaged with the container is close, and when the sheet is tilted in the circumferential direction. Is limited to a small angle, it is difficult to say that it is an exercise device particularly suitable for a turning motion that draws a large circumference.

In the chair-type exercise device described in Patent Document 3, the eccentric cylinder mounting portion having a built-in bearing is obliquely installed at a location away from the center of the rotating body, and the eccentric cylinder mounting portion is located above the eccentric cylinder mounting portion. Since the cylinder is rotatably mounted and the seat is installed on the upper part thereof, the rotation of the ellipse eccentrically with the seat tilted outward in the circumferential direction by the start of the electric motor is automatically performed. Is started.
In such a state, a circular motion is mechanically performed in which the upper body of a user who is seated on the seat and puts both feet on the ground is shaken so as to be thrown obliquely upward and outward from the rotational direction of the seat. At this time, the user can also perform a twisting exercise in which the user turns to the left and right around the waist.
In addition, since the rotation of the seat body is restricted within a certain range while the outer wall surface of the cover portion and the outer wall surface of the seat body are movable in a state of being laid across the bellows, Accidents such as user dropping out can be prevented in advance.
However, the eccentric tube mounting portion lacks a structure for changing the original inclination angle obliquely provided on the upper surface of the rotating body to a different angle.

For example, it is assumed that the eccentric tube mounting portion mainly responsible for the eccentric rotation of the seat body is configured to be detachable and a plurality of types of eccentric tube mounting portions having different inclination angles are provided.
In this case, after a user removes this seat body from the said seat body and removes the said cover part, the effort which replaces with the eccentric cylinder of a different inclination angle arises.
In addition, although the electric motor has a reversing function, it is a rotation by a machine to the last, so it is said that it is an exercise device that can perform a twist exercise or a circular exercise with exercise intensity according to each user's intention or request. It is difficult, and lacks the structure required to carry out the swivel motion depicting the 8 o'clock.
Furthermore, since the structure includes an electric motor, it is unavoidable to increase the weight as compared with the above-mentioned two patent documents. With the chair-type exercise equipment having such a structure, it is a chair for table or office work in daily life. It lacks consideration that doubles as a chair function for computers.
Therefore, although it can be used as a chair-type exercise device under specific circumstances such as for rehabilitation in a medical institution, it cannot be an exercise device that also functions as a chair in daily life.

The fitness chair described in Patent Literature 1 lacks a structure that shakes the upper body to throw it out in the circumferential direction during a turning motion, lacks a structure for performing a circular motion to draw an ellipse, and sits on the seat A device that can efficiently strengthen and strengthen the rectus abdominis and external oblique muscles from the point of lack of a structure where elastic restoring force (stress / drag) acts against the user's movement direction Is hard to say.
Moreover, in the chair used for waist reinforcement | strengthening of patent document 2, although the said spring which bears the elastic restoring force produced against the operation | movement of the user seated on the said seat is attached, this spring is attached to this spring. The elastic restoring force provided is constant, and since it lacks a variable or adjustable structure, the elastic restoring force provided by the spring depends on the user of various physiques or physical strength or the intentions and circumstances of each use. It is hard to say that it is an exercise device that can provide an appropriately variable or adjusted state.
Furthermore, in the chair-type exercise device described in Patent Document 3, the seat is displaced by adjusting the inclination angle of the seat or changing the distance of the eccentric tube mounting portion (eccentric tube) from the rotation axis of the rotating body. The point of lacking a structure that changes the size of the circumference when rotating in mind, the point that it is impossible to carry out the swivel motion that draws the figure 8 on the structure, the addition of a structure that acts against the stress of the user's movement From the point of lack, it is hard to say that it is an exercise device that can appropriately respond to an exercise form or exercise intensity desired by an unspecified number of users each time.

The present invention solves the problems of the known documents described above, and at the same time, when performing the turning motion for drawing an ellipse or figure 8, and the twisting motion for twisting the abdominal waist to the left and right, An object of the present invention is to provide a structure that can change or adjust the elastic restoring force that resists the deformation of the two struts.
Furthermore, the object of the present invention is to provide an appropriate state of elastic restoring force against the deformation of the first strut or the second strut according to the weight and physical strength of various users or the desired exercise intensity or occasional situation. An object of the present invention is to provide a chair-type exercise device that can be adjusted or changed by an easy operation (elasticity) and has safety and is functionally excellent.

In that case, a plurality of locations of the outer wall of the third strut, and take disengaging means to both said projections, protrusions swing of arrangement corresponding to the arrangement設箇offices and number of disengagement means provided in the third strut It preferred you to install more grooves in the strut container.

The chair capable of gymnastic exercise according to claim 4 , wherein the leg portion, the fourth strut made of an elastic material standing on the upper portion of the leg portion, and the upper portion of the fourth strut are connected. The fourth strut includes an elastic body formed into a cylindrical shape using an elastic material, and an outer wall or an inner wall below the upper end of the elastic body. Either one or both of the outer wall and the inner wall of the elastic body is provided with an opening that can accommodate a rod-shaped spring material, and is formed into a cylindrical shape with a material that follows the deformation of the elastic body. Surrounding the outer wall of the elastic body that is provided around a part of the outer wall of the elastic body that extends from the upper end of the elastic body to the upper end of the storage portion that is provided on the outer wall side from the upper end of the elastic body A laterally protruding seat joint and above or below this seat joint Or one or more protrusions provided on the outer wall of the elastic body on both the upper and lower sides, and in a state of being fitted on the upper portion of the fourth support column, a friction surface is provided at a location facing the upper portion of the seat joint portion.

In the above configuration, projected to Rutotomoni said plurality of protrusions around the outer edge of the upper end of the seat joint fourth strut, or on the outer wall side of the elastic body, a space in which the upper end of the seat joint is exposed It is preferable to provide the space , and it is preferable to make the space rigid and smooth.
Further, a projection which Katachi設in thickness different using material rubber was more prepared, top and disengaged (detachable) freely configured to Rukoto of the seat joint is preferred.

In the chair capable of gymnastic exercise according to claim 5 receiving the configuration of claims 1 to 4, a bar-shaped vertical beam member is erected upward from the upper part of the leg portion, and the first strut or the first One or more restricting means that surround the periphery of the two struts, the third strut, or the fourth strut are horizontally provided on the vertical beam member .

In the above configuration, the said longitudinal crosspieces and said regulating means, that you use the sturdy material such as aluminum or stainless steel is preferable.

In the above-described configuration, the first support column, the second support column, the third support column, or the fourth support column is tilted (inclined / curved) and rotated while contacting the frame of the restricting means during a turning motion for drawing a circumference. since it is assumed, it is desirable to Katachi設the shape of the regulating means in a circular.

According to the invention described in claim 1, wherein the longitudinal direction of the first strut (vertical direction), a plurality of spring insert holes opened an opening rod-shaped spring member can accommodate (Osame置) is internally provided Yes.
For example, the same material of the first strut and the same dimensions according, since columnar body having the same shape that does not internally provided the space or opening is dense (there is no part of the cavity), provided as a characteristic in the elastic material refractive Alternatively , an elastic restoring force (stiffness) that works against (deverses) deformation such as bending or twisting acts strongly. Therefore, although the restoring force (returning force) to the original position or the original shape is high, a force is required to deform by applying an external force.

In other words, compared to a high-density columnar body of the same shape made of an elastic material without providing a space in the interior, the first support column in which the spring material is not placed in the spring insertion hole has a lot of space. Since a plurality of corresponding spring insertion holes are provided, the space ratio (the ratio occupied by the space) is high (more) and the state is reduced.
Thus, not internally provided a space or opening, as compared with the columnar body having the same shape made of the same material, restoring force to its original position or its original shape is reduced. On the other hand, since the flexibility and flexibility at the time of bending are improved, it becomes easy to bend (easy to bend).

Therefore, in the first struts and minority Osame置or unpaid place the spring member the spring insertion hole, the curved circumferentially making pivoting movement to draw the circumference, such as shape of the ellipse or 8 (rotational motion) be susceptible to (refraction), since it tends to deform twisted in the horizontal direction, suitable for making according mild circular motion around an axis of the first strut state (turning-turning), in particular, twisting motion Appropriate when performing.
Incidentally, in such a state, it is possible to easily carry out the twisting motion in combination with the turning motion.
Further, regardless of the pay of the spring material numeric (number to be paid), according to the first strut is made using a material having elasticity, the top near the axis point in turning movement the legs be located in this case, since the action point (subject to member behavior) is located near the lower portion of the seat, the starting point when performing the pivoting movement of the user sitting on the seat draws every circumference The axial point and the action point (moving part) are located at a place apart in the vertical direction.

Therefore, in addition to the physical strength spent during turning movement in posture which largely inclined upper body on the outside of the circumferential direction (rotational movement), an elastic restoring acting when the first support body returns to the original shape against deformation of Force (elastic material characteristics) and elastic restoring force that works when the spring material placed in the spring insertion hole returns to its original shape against deformation are added.
Thus, against an elastic restoring force acting on the first strut body and the spring member in seated position on the seat, oval or circle the draw turning (rotation) during exercise or belly, such as time of 8, compared to JP introduced in the 1-3 during twisting motion to torsion the rectus and outer double oblique muscle around the right and left alternately, inevitably requiring physical strength.
Therefore, if the same user has spent turning (rotation) movement or twisting motion using a chair that can exercise a structure according the same time, as compared with Patent Document introduced in the 1 to 3, according user Training of the rectus abdominis muscle and the external oblique muscle and latissimus dorsi muscle is made more efficient.

Further, in the structure that connects the first strut and internally provided with a plurality of spring insert holes opened an opening at the upper end directly below the seat opening (back side of the seating surface), the upper end from the top view of the seat opening of can an opening opened, increased or decreased in and out and to visually confirm the total number and the arrangement of the spring material in which Osame置the spring insertion hole, the spring member according with upstanding posture from the seat it on.
As a result, an elastic restoring force acting against deformation when the first support column is bent (bent) in the circumferential direction during a turning motion, or twisted to the left or right during a twisting motion , or Work when de-energizing (decreasing) can be done easily and easily.

Moreover, along with creating a cross section of the first strut, which opened the opening at the upper end of the transmural setting range <spring insertion hole of the seat opening to the extent that all of the spring insertion holes appear, first strut according to just below the seat opening for the structure to connect the upper of the upper end of the first strut seat opening according, i.e. does not protrude from the surface of the seat surface.
In such a structure, a joining surface between the back side of the seating surface (directly below the seat opening) and the upper end of the first support column can be secured, so that it is possible to provide a reliable fixing means such as adhesion.

Incidentally, the first strut and internally provided with a plurality of spring insert holes in The rewritable opening an opening in the upper vertical direction (longitudinal direction) of, from an opening opened to the upper end while Osame置the spring insertion hole for configuration using a slightly protruding full-length (projection length 10 mm to 20 mm) crafted spring material, by providing the thickness of the projecting length of the spring member <seating surface of (or 30 mm), an opening which is opened to the upper end a situation in which the buttocks of a user and the end of the spring member seated on said seat projecting upon Osame置the spring insertion hole is in contact according the can be avoided.
Thus, according even while Osame置the spring member into a number of spring insert holes made in the full-length, not to bring discomfort to the user sitting on the seat, turning motion to draw any circumference (pivotal movement), or to the left and right alternately twisting twisting motion and the upper body can be comfortably performed.
Further, a first strut opened an opening at the upper end, and a spring member which end portion is made the length protruding from an opening opened to the upper end while Osame置the spring insertion hole, the projecting spring member according in the configuration using a seat having a seat surface made thicker to compensate for the length, by increasing or decreasing the number of spring material which (it should pay) Osame置the spring insertion hole, against the first when strut variant according If variable, or to adjust the elastic restoring force in advance acting Te, workability can be improved when the out by pinching the end of the spring member protruding from an opening opened to the upper end of the spring insertion hole.

Furthermore, in addition to the opening opened to the upper end, opened a little opening in the outer wall of the downwardly from the upper end, by instal bout while transmural set toward the spring insertion hole, with respect to one spring insertion hole There are also measures to open openings at two locations on the upper end and the outer wall slightly below.
In such structure, it is possible to Osame置the spring insertion hole of in a state of being protruded end of the spring member from an opening opened to the lower side (exposed).
In addition, when Osame置the spring member from an opening opened to the upper side, on a distance from the bearing surface, the visibility at the time of confirming the accommodated numeric and arrangement of the spring material according from the seat opening visually Will improve.
Incidentally, slightly opened an opening in the outer wall of the lower from the upper end, in the configuration using the first strut and internally provided with a plurality of spring insert holes nestled in transmural set to Rutotomoni bout towards the spring insertion hole, user and out of the spring member from the opening, which is opened on the lower side in a posture of being seated on the seat, it is possible to increase or decrease the pay registered number of spring material according.
In this case, since it is not always necessary to provide the seat joint portion, it is possible to reduce the cost by shortening the manufacturing process of the seat or by simplifying the mold.

Specifically, an opening opened to the upper end of the spring insertion hole, an opening opened to the outer wall of the lower from the upper end in nestled in the spring insertion hole and a series, opened in two places of the outer wall of the upper and lower in the structure in which the both of the opening can be out of spring material, while Osame置the spring member according to the spring insertion hole, if having a total length of the end portion protrudes from an opening opened at the upper end, the outer wall of the lower in a state where the spring member of the full length of the opening was opened and Osame置the spring insertion hole, the end portion of the spring member according to protrude from an opening that is opened on the lower side.
Spring this case, the elastic restoring force generated in the first time of post deformation that Katachi設the structure of a variable or when adjusting, according the opening by the user is opened on the lower side in a posture of being seated on the seat Workability when inserting and removing materials to increase or decrease the number of storages is further improved.
On the other hand, when Osame置the spring member according an opening that is opened on the upper end side, since it can be easily confirmed visually from above the upper end of the spring member is the seat opening according, viewing of pay stationary state of the spring member according Improves.

In addition, when the user seated on the seat repeatedly performs a circle (turning / turning) motion or twisting motion that draws a circle such as an ellipse or an 8-character, the elasticity of the first support column body as a characteristic and resiliency (Stability), the strength (strength) against the elastic restoring force with a spring material properties that Osame置the spring insertion hole it takes inevitably, the user of the latissimus dorsi and around rectus Complex muscle training can be performed efficiently around the circumference and around the external oblique and mid gluteus muscles (hereinafter referred to as muscle groups).
Note that the swivel motion that draws the figure 8 or the twist motion that alternately twists the left and right sides of the lower back part of the muscles strengthens the muscle group and at the same time acts as a peristaltic motion of the digestive organs. It also contributes to improving the aesthetics of the body by dieting and tightening around the abdomen.

According to the invention described in claim 2, wherein by circumferentially the housing part only on the outer wall of the elastic body, when the second strut structure you open the opening at the upper end of the housing portion of transmural setting of the seat opening Is not necessarily required. Therefore, cost reduction due to simplification of the manufacturing process of the seat can be expected.
Meanwhile, the by circumferentially the housing part only on the inner wall of the elastic body, according a second pillar structure you open the opening at the upper end of the housing portion or the outer and inner walls both circumferentially provided a housing portion of said elastic body, to, according a second-post upper end you open a open structure of the housing portion, transmural setting range of the seat opening to the extent that opening opened to the upper end of the housing portion that is provided around the inner wall is visible <by Katachi設the cross-section of said elastic member, when connecting the upper end of the elastic body directly below the seat opening, according upper upper end of the seat opening portion of the elastic member, i.e. the surface of the seat surface It does not protrude.
In such structure, the rear side of the seat surface (just below the seat opening), the junction surface between the upper end of the elastic body can be secured, it is possible reliable fixation take measures, such as adhesive.

Incidentally, opening the aperture to open to the upper end of the container portion provided around the inner wall side the The rewritable opened in the upper end equivalent position of the elastic body (height), the upper end of the container portion provided around the outer wall side slightly from the second support structure you arranged on the lower side of the opening from the upper end of the elastic body, while Osame置the housing portion of the full-length (protruding length 10mm which slightly protrudes from an opening opened at an upper end for a configuration using a spring member made in to 20 mm), by providing the thickness of the projecting length of the spring member <seating surface of (or 30 mm), opened in the upper end of the housing portion that is provided around the inner wall side and the buttocks of the user end and seated on the seat of the spring member from the opening of projecting upon Osame置the spring insertion hole can be avoided in contact.
Thus, according even in a state where the Osame置the number of housing portion a spring member made in the full-length, not to bring discomfort to the user seated on the seat surface, pivoting movement to draw any circumference (pivotal movement), or to the left and right alternately twisting twisting motion and the upper body can be comfortably performed.

In this structure, since also the upper end of the spring member of the full-length according to Osame置from an opening opened to the upper end of the housing portion of the outer wall side projects, in a posture where the user is seated on the seat is provided around the outer wall side From the opening opened in the upper end of the accommodating part which exists , the spring material of the said full length can be taken in and out, and the number of accommodation can be increased / decreased.
Therefore, the by circumferentially the housing part only on the outer wall of the elastic body, according a second pillar structure you open the opening at the upper end of the housing portion or the outer and inner walls both circumferentially provided a housing portion of said elastic body, to, workability when adjusting the elastic restoring force generated at the time of deformation of the second support structure you open an opening at the upper end of the housing portion according improves.
Incidentally, a second pillar structure you circumferentially provided a housing portion of only the outer wall of the elastic body, while Osame置the housing portion of, made the length of slightly protruding from an opening opened at an upper end In the case of a configuration using a spring material, it is not always necessary to penetrate the seat opening.
Therefore, it is possible to make the seat thin and light and to simplify the manufacturing process.

In addition, when Katachi設the first strut and the elastic member in the outer shape of the same size using the same material, the first strut according is provided inside a plurality of spring insert holes in the longitudinal direction (vertical direction) against being Katachi設the columnar body was, the elastic body has a wall surface at two positions of the outer and inner walls is formed in a tubular shape having a space inside the inner wall.
Therefore, although the rigidity is slightly inferior to that of the first support column, the peripheral portion of the accommodating portion that plays the same role as the spring insertion hole is either the inner wall or the outer wall , because the number of wall surfaces and the wall surface area are increased. Alternatively, both the inner wall and the outer wall, the number of peripheral arrangements of these accommodating portions and the choice of the wall surface to be arranged are diversified.

Further, the accommodating portion since the form set by the material to be driven to the deformation of the elastic body, regardless of the wall you circumferentially provided a housing portion of, the spring material in which Osame置the housing portion according seated on the seat Deforms according to user's actions.
In a state of, in addition to the elastic restoring force it included as a characteristic (Stability) the elastic body made of material having elasticity, the elastic restoring included as a characteristic (Stability) in Osame置the spring member in the housing portion of Power is added.
Contrary, in the second post condition that the spring member has unpaid location in the housing portion of the point at which the elastic body is formed into a cylindrical shape by using a material having elasticity, rod-shaped spring member accommodating portion according with instal an elongated shape but with a capacity, in terms of the form set by the material to be driven to the deformation of the elastic body, according to the second strut (operation of a user sitting on the seat) deformation upon the (elastic) The accommodating part does not have a great influence.

For example, the outside dimensions of the same first support and the elastic body, when Katachi設the internal dimensions of the spring insertion hole and the housing portion in the same circumferential accommodating unit according to both the inner and outer walls of the elastic body in the second struts set, it is clear that compared to the inner設数spring insertion hole according, the housing portion of the circumferential設数according above.
Further, the accommodating unit according than the second struts circumferentially provided on one of the outer wall or inner wall in the second struts circumferentially provided a housing portion of the both inner and outer walls, the housing portion of the circumferential設数according terms you increase, it is possible to increase the absolute pay registered number of spring material (the total number of paid to put).
Therefore, according outer wall of the housing part and the elastic member or the second support as compared to the second support column that is provided around the one of the inner wall was provided around the accommodating unit according to both the inner and outer walls of said elastic body, It is an advantage that the range of adjustment of the elastic restoring force that works against deformation of the material further expands from low elasticity to high elasticity.
In particular, full length protruding from an opening accommodating portion opened an opening at the upper end is opened and the second support column that will be circumferentially provided on both the inner and outer walls of the elastic body, the upper end while Osame置the housing portion of in the configuration using a spring member having, according slightly biasing the elastic restoring force acting on the second support, or if the fine adjustment with de-energized, in a posture where the user in the seat is seated, provided around the outer wall side from the point may correspond to increases or decreases by out by pinching the upper end of the spring member protruding from the opening of opened to the upper end of the housing portion that is, is improved workability and convenience in the state of.
Further, housing portion to effect amount of the elastic restoring force acting on the spring member is unpaid standing time (during low elasticity) and full payment standing time (at high elasticity) (stress applied to: when a load on the object is applied, the load inside the object since the force differential) which tries to keep the resistance to balance the you amplified, alter the action of the elastic restoring force in the context of the exercise intensity or each time, the (degree of stress acting on the second time post modification according) If you have more choices.

On the other hand, anti-accommodating portion, which opened the opening at the upper end when the second strut inner and outer walls both in you circumferentially provided structure of the elastic body, the deformation direction while the spring member was nonpayment location in the housing portion of the elastic restoring force to act in, that was formed in a cylindrical shape from a material having elasticity the elastic body, with instal the elongated shape of the housing part accommodating the rod-like spring member according to follow the deformation of the elastic member from what has been shaped set at material, which assumes the same state, the elastic restoring acting against the time variation of the second strut of the outer wall or you circumferentially provided a housing part in one of the inner wall structure of the elastic body It corresponds to power.
Accordingly, the container portion circumferentially provided to both the inner and outer walls of the elastic body, women in the second post in a state in which the spring member and unpaid location, weight is light user, or weak weak elderly or force of strength Suitable for mild implementations such as turning (twisting) motion or twisting motion , or swinging motion that moves straight forward, backward, left, right or diagonally Has low elasticity (low elasticity).

On the other hand, all of the container portion circumferentially provided to both the inner and outer walls of the elastic body, the elastic restoring force generated against the deformation of the second support column in a state of Osame置the spring member is of the elastic body all of container portion provided around the one of the outer wall or inner wall, above the elastic restoring force generated against the deformation of the second support column in a state of Osame置the spring member.
Therefore, the all of the container portion circumferentially provided to both the inner and outer walls of the elastic member, the second support column in a state of Osame置the spring member, weighing heavy user, or physical strength of the strong user or intensity such user who desires to exercise achieve the high elasticity suitable for strength at implementation of such pivoting movement or twisting movement draw circumference such shaped oblong or 8 seated in the seat.

Further, the outer wall of the elastic body or as compared to the second support column that circumferentially provided a housing part in one of the inner wall, in the second struts and circumferentially provided a housing portion on both the inner and outer walls of said elastic body, since accommodation of the circumferential設数according is increased, the biasing (enhancement) an elastic restoring force against the deformation direction, or when the energy dissipation (decreased) to fine tune the decrease of paid registered number of spring material It can be changed little by little.
Further, since the spread distance of the maximum value and the minimum value of the paid registered number of the spring member for accommodating section according the difference of the elastic restoring force of the action quantity that occurs during deformation (minimum and maximum) increases.
Accordingly, the second struts and circumferentially provided a housing portion on both the inner and outer walls of the elastic body, a state in which the spring member and unpaid location, while Osame置the spring member for all of the housing portion, first according The elastic restoring force (stress / stability) acting when the two struts are deformed is significantly different.
Thus, the outer wall or the housing part in one of the inner wall than the second support column that will be circumferentially provided, to slightly modify the elastic restoring force acting upon the deformation of the second strut (stress-righting) from significantly according, Further fine adjustment is possible, and it is advantageous in that it can be adjusted to a more appropriate state (elastic restoring force) according to irregular demands of an unspecified number of users.

Furthermore, a housing part accommodating portion opened an opening at its upper end provided around the outer wall side of the second strut the Ru is circumferentially provided on both the inner and outer walls of the elastic body and disposed at regular intervals, according In addition to opening an opening in the outer wall exposed between the accommodating portions, there is also a measure that penetrates to the accommodating portion provided on the inner wall side and continues.
In this case, the second pillar structure according, while Osame置the housing portion of, in the configuration using a spring member of the full-length protruding from an opening that is opened in the upper end, housing portion according the inside of the elastic member that it is circumferentially provided on both of the outer wall, in addition to the opening opened to the upper end, the rewritable open an opening in the outer wall of the elastic body, it has nestled in the housing portion and a stretch which is provided around the inner wall side Therefore, the end of the spring material placed in the housing portion on the outer wall side protrudes from the opening opened on the upper end, and the end of the spring material placed in the housing portion on the inner wall side opens on the outer wall side Protrude from.
In the configuration according, although peripheral設数accommodating portion of the outer wall is reduced, that has opened the opening at the upper end of the housing portion that will be provided around the outer wall side, the housing portion that will be provided around the inner wall side, an upper end from a point established openings in two places of the outer wall, into and out of the spring member of the full length of the container portion circumferentially provided to both inner and outer walls, not essential and that the user away from the seat.
Therefore, workability in the elastic restoring force against the second strut deformation according to increase or decrease the pay registered number of spring material according variable or adjusting is further improved.
Incidentally, in such a structure, it is not always necessary to penetrate the seat opening, so that the seat can be made thin and lightweight.
In addition, the manufacturing process of the seat can be simplified and the production cost can be reduced by reducing the amount of raw materials used.

For example, it is generally known that the quality of sleep is improved by performing muscle relaxation exercise before sleep. In this case, on the user considering their weight and health condition, or a small number of spring material that Osame置the spring insertion hole or housing portion, by a non-payment location, the first strut or The elastic restoring force resisting the deformation of the second support can be reduced.
Therefore, a small number of spring material Osame置or in the first strut and second strut state unpaid location, mild rocking the linear motion back and forth lateral or oblique direction with weakness state represented by rocking chair, It is also possible to provide a low elasticity suitable for exercise.
In this case, since the swing motion corresponds to the muscle relaxation motion, it is possible to improve the quality of sleep and at the same time obtain a relaxing effect.

Further, even in the first strut or the second struts circumferentially provided with the receiving portion in both of the inner and outer walls of the second post or the elastic member accommodating portion which circumferentially provided only on the inner wall of the elastic body, the spring for insertion hole or you open the opening at the upper end of the housing portion structure, a spring insertion hole from an opening opened at an upper end or a situation of the housing portion (pay location status of the spring material), Osame置the housing portion of end of the spring material, it is possible to visually confirm from the top view of the seat opening can be changed without difficulty to determine the placement and pay numeric spring member.
In particular, in the second struts circumferentially provided a housing portion on both the inner and outer walls of the elastic body, the wall surface to place the housing portion according to diversification, the dose could be increased the number of spring material that Osame置the housing portion of Therefore, the elastic restoring force generated at the time of deformation of the second support column can be adjusted to a more appropriate state.
In addition, since the elastic restoring force generated when the second support column is deformed can be greatly varied, it has the versatility that can meet the needs or physical abilities of many unspecified users.

Further, in the configuration using the second support column in which the storage portion is provided on both the inner and outer walls of the elastic body, regardless of the number of the spring members, the rotation motion (rotation motion) that draws any circumference can be obtained. The axial point (starting point) is in the vicinity of the leg portion, and at this time, the operating point is below the back of the seat (above the second support column) (the distance between the starting point and the operating point is From the state of being separated in the vertical direction), the point of action of the second support column and the user's body (particularly the upper body) can perform a circular motion with a posture in which the user leans outward in the circumferential direction.
In a state of strong acting upon returning to the posture in which the second pillar of the housing portion is circumferentially provided on both the inner and outer walls are upstanding from inclining greatly (deformed) state in the circumferential direction of the elastic body (righting) against the elastic restoring force, the user of the rectus abdominis muscle and the external double oblique muscle around and latissimus dorsi performing pivotal movement posture tilted larger body outer circumferential direction is inevitably training.
Thus, from Rukoto be performed even more efficient complex muscle training on muscle groups of the user, it is possible to further strengthen the strength (strength).

Moreover, said elastic body is formed in a cylindrical shape, the housing portion of is the form set by the material to be driven to the operation of the elastic body, and a small state nonpayment location or pay numeric, the spring member in a second strut, and because the space factor (housing part spring member is not Osame置) occupies more easily deformed so Takeru flexible and flexibility.
Therefore, in the second support column in which the spring material is not placed in the storage portion provided around the inner and outer walls of the elastic body or in a state where the spring material is placed in a small number, the user sitting on the seat puts both feet on the ground. When performing a twisting motion that twists around the waist in the posture, the elastic restoring force (low elasticity) suitable for it is exhibited.

For example, if a swinging exercise and a twisting exercise that draws a circle such as a figure of 8 or an ellipse are routinely practiced using a chair capable of gymnastics according to claim 1 or 2, the first strut body or the elastic restoring force generated at the time of deformation of the second strut body (elastic body), an elastic restoring force is added which occurs during deformation of Osame置the spring member the spring insertion hole or the housing unit, driven by the variations of these post Thus, the rectus abdominis muscle and the external oblique muscle of the user against the elastic restoring force enhanced by this are further trained and strengthened.
In this case, not only training and strengthening of physical abilities, but also the waistline is squeezed to emphasize the waistline.
Moreover, the circular motion or twisting motion to draw a figure eight since doubling as peristalsis of the digestive organs, at the same time healthy when side effects such as elimination of constipation coupled is slim and excellent in aesthetic The body shape can be maintained. These effects are especially pleasing for women.

Collision According to the invention described in claim 3, and provided around the seat joint at the upper end below the outer wall of the third strut, the seat joint according upward, or one or more projections on the lower or the upper and lower both of the outer wall in structures set, the upper to the post fitting hole of the third strut while fitted over according, points having a friction surface at a position facing the upper part of the seat joint according, with corresponding to the arrangement of such projections, the from the viewpoint projection that vertically the projections swaying interval loosely fitting point is horizontally provided in the post container, a post container of such structure on the lower side of the seat opening, removable seats according to the third strut according It can be configured freely.
In such structure, the seat of which a strut insertion hole of the upper portion of the third strut placed in a state of being fitted over is idle on the left and right above the seat joint according.
Furthermore, above or below the seat joint according or point where the horizontal set of one or more projections according to the outer wall of the upper and lower both were horizontal set the projection swaying of arrangement corresponding to the locations of these projections and the lateral set the strut container from the point that vertically below the seat opening of, projections wobbled groove according to the rotation of the seat according to idle above the seat joint according to the follower.
Therefore, according projections thickness of loosely fitted to Ru projections swinging groove, or differs by a distance between projections wobbled groove, according to the projection wobbled groove according at any time during seat rotation according protrusion Abut.

More specifically, the circumferentially seat joint to the outer wall below the upper end, above or below, or you horizontal set of projections made of rigid material on the outer wall of the upper and lower both structures, of the seat joint first When a user sits on the seat (seat surface) attached to the top of the three struts by attaching the strut insertion hole and performs a twisting motion, the protrusion swinging that follows the rotation (rotation) of the seat An external force is generated when the hard protrusion comes into contact with the inner side of the moving groove .
In a state of the point of projection is made of a hard material, the third strut force generated during abutment of the projection wobbled groove according terms which are made of material having elasticity, and according protrusion according found through the outer wall of the third strut according that propagates to the third strut body.
The Re its third elastic restoring force provided as a characteristic to the strut, the spring insertion synergistic action of the resilient restoring force with the Osame置the spring member into the hole will drag (elastic restoring force, stress) to invert the seat according according switches to be reflected in the user to perform a twisting motion in a posture of being seated on the seat surface of.

Moreover, by circumferentially seat joint to the outer wall below the upper end, upper or lower, or third pillar structure you horizontal set of projections made of material having elasticity in the outer wall of the upper and lower both of the seat joint In the case of performing a twist motion in a posture in which a user is seated on the seat (seat surface) that is attached to the upper portion of the column by inserting the column insertion hole, the inner side of the protrusion rocking groove that follows the rotation of the seat to when the projections began to deform at the same time when an external force contact is applied an elastic, acts an elastic restoring force provided as a characteristic is first according projections, the drag to reverse the seat according (elastic restoring force, stress) Switch.
Subsequently, in addition to the deformation of the protrusion, that is, when restoring to the original shape from a state greatly deformed as the external force increases, in addition to the amplified elastic restoring force (strong drag force that reverses the seat) acting on the protrusion, caused by a third force that is propagated through the outer wall of the strut according the state of the protrusion according the elastic restoring force acting against the deformation of the third strut body, against the deformation of the spring member that Osame置the spring insertion hole A synergistic effect of elastic restoring force that works is added. The Re their drag to further strongly inverted seat according (stress-elastic restoring force) acts.

Therefore, above or below the seat joint according protrusions made of rigid material or as compared to the third pillar structure you laterally disposed on the outer wall of the upper and lower both, material having elasticity like the first strut crafted above or below the seat joint according protrusions or third pillar structure you laterally disposed on the outer wall of the upper and lower both the seat force (elastic restoring force, stress) to reverse the rotation of the related more amplified in Is done.

According to the invention described in claim 4, the seat joint portion is provided around the outer wall of the elastic body that extends from the upper end of the elastic body to the upper end of the housing portion on the outer wall side, and above, below or below the seat joint portion. In the structure in which one or more protrusions are provided on both outer walls, a friction surface is provided at a position facing the upper portion of the seat joint portion in a state where the column insertion hole is fitted on the upper portion of the fourth column. From the point corresponding to the arrangement of the protrusions, the protrusion rocking groove of the interval in which the protrusions are loosely fitted is provided in the support container, and the support container having the structure is provided below the seat opening. Thus, the fourth support column and the seat can be configured to be detachable.
In such a structure, the seat installed in a state where the column insertion hole related to the upper portion of the fourth column is fitted is swung to the left and right above the seat joint portion.
Further, a column container in which one or more protrusions on the upper and lower or both upper and lower outer walls of the seat joint portion are horizontally provided, and a protrusion swinging groove is disposed corresponding to the position where the protrusion is horizontally provided. From the point which hung down to the lower side of the seat opening part, the protrusion rocking | fluctuation groove | channel which concerns on rotation of the seat which idle | rotates above the seat junction part follows.
Therefore, depending on the thickness of the protrusion loosely fitted in the protrusion rocking groove or the interval of the protrusion rocking groove, it depends on the protrusion rocking groove at any time during the rotation of the seat. The protrusion comes into contact.

An elastic body having a structure in which a seat joint portion related to the outer wall below the upper end is provided around and a projection made of a hard material is laterally provided on the upper or lower portion of the seat joint portion or both upper and lower outer walls. When a user sits on the seat (seat surface) attached to the upper part of the support column to fit the support column insertion hole and performs a twisting motion, the protrusion swings following the rotation (rotation) of the seat. An external force is generated by a hard protrusion coming into contact with the inner side of the moving groove.
In such a state, from the point that the protrusion is made of a hard material, the elastic body is made of a material having elasticity, and the housing portion is formed of a material that follows the deformation of the elastic body The external force generated when the protrusion and the protrusion rocking groove are in contact with each other propagates to the fourth column main body, that is, the elastic body through the outer wall of the fourth column (elastic body).
As a result, the synergistic effect of the elastic restoring force provided as a characteristic of the fourth prop body and the elastic restoring force of the spring material placed in the accommodating portion is switched to a drag force (elastic restoring force / stress) that reverses the seat. This is reflected in the user who performs the twist exercise with the posture seated on the seating surface.

Further, a seat joint is provided around the outer wall from the upper end of the elastic body to the upper end of the housing portion on the outer wall side, and elasticity is exerted on the outer wall of the elastic body above, below, or both above and below the seat joint. When performing a twist exercise in a posture in which a user is seated on the seat (seat surface) attached to the upper portion of the fourth strut having a structure in which a protrusion made of a material having a horizontal structure is fitted and attached to the strut insertion hole. When the elastic protrusion comes into contact with the inside of the protrusion rocking groove that follows the rotation of the seat and external force is applied, and at the same time, the elastic restoring force provided as a characteristic acts on the protrusion first. Then, it switches to the drag (elastic restoring force / stress) that reverses the seat.
Subsequently, in addition to the amplified elastic restoring force (strong drag force that reverses the seat) acting on the projection when the projection is deformed, that is, when the original shape is restored from the state of being greatly deformed as the external force increases, The elastic restoring force that works against the deformation of the main body of the fourth strut caused by the external force propagated through the outer wall of the elastic body (fourth strut) from the protrusion in such a state, and the deformation of the spring material stored in the accommodating portion The synergistic effect of elastic restoring force that works against this is added. Thereby, a drag force (stress / elastic restoring force) that reverses the seat more strongly works.

Therefore, compared with the first support column, compared to the fourth support column of the structure that the protrusion made of a hard material is laid on the outer wall of the elastic body above or below the seat joint, or both above and below, In the fourth strut with a structure in which protrusions made of an elastic material are installed on the upper or lower side of the seat joint, or on both upper and lower outer walls, the drag (elastic restoring force / stress) that reverses the rotation of the seat Is more amplified.

According to the invention of claim 5 , which receives the configuration of claims 1 to 4 , a vertical beam is erected on the upper portion of the leg portion, and the first column according to claim 1 or claim 2 is provided on the vertical beam. fourth strut (hereinafter, first, second, third, fourth strut) of the third strut or claim 4 according to a second post or claim 3 according to the horizontal one or more regulating means surrounding the from what has been set, a tilting toward the circumferential direction when these struts pivot swivel area (curved-rotation) is restricted by the restricting means in accordance.
Specifically, the region when the first, second, third and fourth support columns according to claims 1 to 4 turn (turn) while being inclined (curved) in the circumferential direction, and the restricting means related to these support columns of origin at the time of bending (refracting) when contact with in the frame is the frame space of whether to horizontally provided above or below the longitudinal crosspieces or, or according regulating means according to regulating means according wide different pivoting range limit depending narrow, vertically between the upper leg origin according from the lower side of the seat opening during the bending (during tilting).

As an example, when a user seated on the seat performs a turning motion while tilting his / her body in the circumferential direction, the first support column according to claim 1 or the third support column according to claim 3 and according to claim 2 or 4 The elastic body (2nd and 4 struts) is made of an elastic material, the spring insertion hole is built in the 1st and 3rd struts, and the housing is deformed (behavior / motion) the terms are made of a material which is driven, the starting point of time of the pivoting movement (axis point) is at the upper side near the leg of, power point (working point) is located in the lower vicinity of the seat opening.
In the 1st and 3rd struts or 2nd and 4th struts in such a state, the distance between the pivot point and the action point becomes larger by the total length of the struts, so that the posture of the upper body is greatly inclined in the circumferential direction. Suitable for carrying out a swivel motion that draws a large circumference.

Meanwhile, regulations first and third container portions were provided around the outer wall of the outer wall or the elastic body of the strut, or according the 2.4 degree narrow frame adjacent to the outer wall of the elastic body according exposed at the top of the column according facilities means, in the structure surrounding these surroundings, is driven to a point 1st, 3rd strut and the elastic member is made of a material having elasticity, housing portion deformation of the elastic body according to (behavior and operation) according material From the point formed by the above, it is highly probable that the upper portions of these struts come into contact with the frame of the regulating means during the turning motion.
Therefore, according accommodating portion is provided around the inner wall of the outer wall or according elastic member of the first-3 post, or outer wall of the elastic body is exposed to the upper portion of the second-4 struts, the framework of the regulating means according At the time of contact, the starting point when these columns tilt (tilt) in the circumferential direction shifts upward.
Thus, the tilting angle toward the circumferential direction of the 1st, 3rd strut or the second-4 post is restricted according, area user sitting on the seat to pivot in the circumferential direction is naturally limited.
Therefore, from the fact that certain of safety is conservation without limiting their own behavior and consciousness, circular motion, or before and after a user sitting on the seat draw a variety of circumference, such as shaped oval or 8, -The safety when performing a swinging motion that moves linearly in the left-right or diagonal directions is greatly improved.

In the configuration according, according near the abutting portions in the frame of the first-3 post or second-4 struts according regulating means, so it corresponds to the principal origin when these struts is bent (curved), according regulating means If a vertical crosspieces position you horizontally provided in (height) the same according to, the wider frame space of the regulating means according the first, second and third according to claims 1 to 4 including the seat 3. The range in which the fourth support column rotates while tilting in the circumferential direction during the turning motion is widened, and the angle (curvature angle) at which these support columns are deformed like a bow increases.
On the other hand, as the frame space of the regulating means you horizontal set point is according the same position is small, the first, second and third and fourth strut according to claims 1 to 4 including the seat during pivoting movement The range of rotation while tilting in the circumferential direction becomes narrower, and at the same time, the angle (curvature angle) at which these pillars deform into a bow becomes narrower.

Furthermore, when a user sits on the seat and performs a turning motion that draws a large circumference, the first, second, third, and fourth support columns according to claims 1 to 4 are curved (inclined) in the circumferential direction.・ An excessive increase in the angle of refraction (refraction angle / bending angle) can be prevented in advance.
Therefore, it is possible to avoid an accident in which the user's buttocks accidentally falls away from the seating surface during the turning motion or the body is bruised with furniture or the like nearby.
Incidentally, the upper portion of the vertical crosspieces of the first-3 post, or the second-4 post narrow frame is provided regulating means having enough to close to the outer wall of the (elastic body) according case of transverse setting, weight according when extremely heavy user is seated on the seat, it remains in the upper above the flat (collapse) is according regulating means above the first-3 strut or according 2nd and 4th posts (elastic body) according.
At this time, the seat surface (seat) ~ according 1st, 3rd strut or the second-4 post user weight according the order of the longitudinal crosspieces - according legs according-regulating means (elastic member) according ~, i.e. The weight for the seat is propagated.
In a state of, according 1st, 3rd strut or from to stay in the upper above the flat (collapse) is according regulating means of the second-4 post (elastic body), the user safety and according, these struts small a function of turning in the circumferential direction while scale, a function of linear motion back and forth lateral or oblique direction, the ability to rotate in a certain range of lateral bidirectional (up the projection into the projection swinging groove abuts) And are preserved.

Moreover, in the 1st support | pillar which concerns on Claim 1, the 3rd support | pillar which concerns on Claim 3, or the 2 and 4 support | pillar which arrange | positions an accommodating part only in the inner wall of an elastic body, compared with a normal chair support | pillar on the external appearance , according although first-3 post or according 2nd and 4th strut slightly large furnished than ordinary chair posts and the spring insertion hole from the appearance of these struts or housing portion, disposed therein Invisible. For this reason, there is no sense of incongruity and the beauty of the interior is not impaired.

The present invention is characterized in that it brings about various effects due to the actions performed by the various functions described above.
Therefore, the seat that is indispensable when the user sitting on the seat performs a twisting motion , a circular motion in which an ellipse or a figure of 8 is drawn , or a swinging motion that moves straight forward, backward, left, right, or diagonally. Instead of the conventional chair support to support, elastic restoring force that works against the weight (user's weight) that works in the whole vertical direction at the same time as sitting, and elastic restoration that works against deformation at the same time as the user's activation force variable, or adjusted to allow the provision of first strut and the second strut according to claim 1 or 2 structures that can be performed in an easy procedure to be energized or de-energized by.

In addition, using a common upward or downward, or respectively in the form of a third strut or fourth strut according to claim 4 according to claim 3 in which the projection has lateral set according to the outer wall of the upper and lower both of the seat joint according the strut container according to claim 3 or 4 capable from what has been vertically below the seat opening, and configuring the seat according to these posts detachably, and an elastic restoring force acting during turning movement, It embodies the distinction of elastic restoring force that works during twisting motion.

Further, a tilt in the longitudinal crosspieces than annexed regulation means according that are horizontally provided, toward the circumferential direction of the first, second, third, fourth strut according to claims 1 to 4 in accordance, pivoting range ( It also has the function of ensuring the safety of the users by limiting the rotation area) and the movement function of these columns.
With these functions, when a user sitting on the seat performs a complex circular motion that intertwines a twist motion during a swing motion , or a twist motion or a swing motion that draws various circumferences, etc. The choice of exercise strength (elastic restoring force) (the number of spring insertion holes provided internally and the number of housings provided circumferentially) has a variety that can meet the needs of each time.

For example, the first and third struts according to claim 1 or 3 or the second and fourth struts (elastic body) according to claim 2 or 4 and a restricting means that surrounds and surrounds the struts. weighing heavy users to the seat structure you laterally disposed above the longitudinal crosspieces are assumed to perform circumferential motion or twisting motion to draw a shape oblong or 8 seated according.
In this case, the frame of the restricting means is so narrow that it is close to the periphery of the first / third struts or the second / fourth struts, and the upper periphery of these struts (elastic bodies) is surrounded by the restricting means. Therefore, in a state where a small number of spring materials are placed in or not placed in the spring insertion hole or the housing portion, the ratio of space (total number of spring insertion holes or housing portions> the number of spring materials placed) is high and low elasticity. The degree of flatness (deformation) when these heavy pillars are deformed when a heavy user sits on the seat installed on the upper part of the first , third or second and fourth pillars in such a state. remains above the restriction means according as it becomes larger than the frame space of the regulating means according.
In this case, weighted against the seat, that is propagated to the leg of the final through longitudinal crosspieces of the regulating means the weight of the user is related to automatic, dispersed in the seat-regulating means, the longitudinal crosspieces, legs Therefore , the first and third struts or the second and fourth portions positioned below the regulating means are not affected by flatness (during deformation).
In a state of the upper lateral flattened (deformed) the 1st, 3rd post or second-4 post according the shape, free-standing above the portion that horizontally provided in the longitudinal crosspieces of the regulating means according as a starting point and functions screw in the left-right horizontal direction in a state that a function of linear motion back and forth lateral or diagonal direction although becomes usually slightly compared to when the function of turning while being slanted in the circumferential direction is preserved.
These struts are safe preservation of the user because it is avoided by the longitudinal crosspieces and according regulating means also according to refraction or lodging.

By the way, prepare multiple bars made of a hard material with the same outer dimensions as the above-mentioned spring material, and place these bars in a spring insertion hole or accommodation part with an opening at the top. by, it is also possible to disable tilt the 1st, 3rd post or second-4 post according.
In this case, the safety at the time of using the chair which can be exercised according to the present invention as a chair for everyday use such as an office chair or a dining table chair is remarkably improved.
Furthermore, when the slightly shorter overall length of the bar than the entire length of the spring insertion hole or housing portion and a plurality Osame置, part of the upper spring insertion hole or housing portion serves as a space, first 1.3 post or second-according A part of the upper part of the four struts is easily twisted and bent in the left-right direction.
Therefore, twisting can be performed, and the space is limited to a part of the spring insertion hole or the upper part of the accommodating portion, so that excessive tilting of the seat cannot occur.
Therefore, it also functions as a chair for everyday use, such as office work or a table that can be stretched lightly, such as a twisting movement and a turning movement that draws a small circumference.
By the way, at the time of twisting movement, the elastic restoring force comparable to the elastic restoring force originally provided in the first or third support column or the second or fourth support column in the state where the spring material is not placed in the spring insertion hole or the accommodating portion is used. Acts against the direction of rotation.

In the chair which can be exercised according to the present invention, the first and third support columns according to claim 1 or 3 corresponding to a conventional chair support column are formed in a column shape using an elastic material, and according to claim 2 or 4 The elastic body is formed into a cylindrical shape using an elastic material.
In addition, according to the first and third struts have been internally provided a plurality of spring insert holes, whereas either of the outer wall or the inner wall of the elastic body forming the second-fourth strut according or inner and outer walls both, the plurality of accommodating portions made of a material that follows the deformation of the elastic body according is circumferentially provided.
Therefore, swivel motion (circular motion) that draws a large circumference such as figure 8 or ellipse and twist motion and swing motion that moves linearly back and forth or diagonally , or twist motion in parallel during circular motion possible and to, by increasing or decreasing the number of spring material that Osame置the spring insertion hole or housing portion in a state of deformation of the first and third struts or second-fourth strut according from the time activation of the user that The elastic restoring force against this can be varied and fine-tuned.
Thus, the lack of structure for performing a rocking motion to linear motion circular movement as well as longitudinal and lateral or diagonal direction draw characters of Patent Document 1 ellipse is fitness chair faced problems described or 8, The lack of a structure that applies stress (resistance force) against the user's direction of movement during these exercises has been solved.

Further, in the chair that is used to strengthen the waist of Patent Document 2, since the lack of attached structures that elastic restoring force urging the or energy dissipation, acting on a spring which connects the upper and the upper end portion of the connecting portion and varying the elastic restoring force acting on the spring in response to different weight or intentions and status of each of the user or users of various physical, and it is impossible to adjust.
However, that the first and third struts and the elastic body according to claim 2 or 4 according to claim 1 or 3 was made of a material having elasticity, a plurality of longitudinally rod-shaped spring material of these struts can accommodate that provided the spring insertion hole or housing part, from the time of activation of the user, depending on the variable, or an unspecified number of users an elastic restoring force against the deformation of the strut by increasing or decreasing the paid registered number of spring material from appropriate state point you a function of adjusting the (elastic restoring force) to solve the problems faced by the chair that is used to strengthen the waist.
Furthermore, in the state which the user sat down on the said seat and put the foot | leg on the floor surface, and inclined the gravity center to the circumferential direction, the 1st , 3 support | pillar which concerns on Claim 1 or 3 , or Claim 2 or 4 From the point that the starting point at which the second and fourth support columns tilt is in the vicinity of the upper part of the leg and the action point (moving part) is in the vicinity of the lower part of the seat, a swivel motion that draws a large circumference is possible. The problem that the chair used for strengthening the room has has been solved.

The chair-type exercise device described in Patent Document 3, although the structure to reverse the motor is is being attached, the attached structure for varying an inclination angle in a state in which the eccentric cylindrical mounting portion is obliquely on the upper surface of the rotary body Lack.
In addition, the angle of inclination when the seat is attached is also fixed, and the distance from the rotating shaft of the rotating body to the eccentric tube mounting part (eccentric tube) can be changed to change the size of the circumference when the seat rotates It also lacks the attachment.
Therefore, during the circular motion automatically triggered by the activation of the electric motor, the twist motion can be performed within a range in which the rotation is limited by the bellows.
On the other hand, it is structurally impossible to perform a swinging motion that linearly moves back and forth, right and left or in an oblique direction and a turning motion that draws an irregular circle such as a figure 8 or an ellipse.

In chair can exercise according to the present invention, however, the columnar body formed by the resilient material in place of the conventional chair support column, that to constitute a first strut of a plurality of spring insert holes that will be installed inside the columnar body in addition, an elastic body formed into a cylindrical shape by elasticity of the material, either one of the outer wall or inner wall of the deformation of the elastic body (behavior) form setting a material to be driven to be Rutotomoni according elastic body, or inner from the viewpoint of a plurality of housing portions that will be circumferentially provided on both the outer wall and constituting the second support column, pivoting movement as well as to draw various circumference of such shaped oblong or 8, without reduced during pivoting movement Implementation was possible with the user's upper body leaning outward in the circumferential direction. In addition, twisting movements and swinging movements that move linearly in the front-rear, left-right, or diagonal directions are also possible.
Further, in practicing by combining various motions described above, the first and third struts or drag the direction (deformation direction) operation of the second-fourth struts acting in the opposite direction according to (elastic restoring force) adjusted by energizing or de-energized by increasing or decreasing the pay registered number of spring material, or comprises a variable functions.
Incidentally, in the first and third struts or second-fourth strut constituted by using a spring insertion hole or housing portion opened an opening at the upper end was formed through the seat opening near the center of the seat surface If the point was fixed to these posts immediately below the seat opening of spring material that is Osame置the container portion provided around the inner wall side of the spring insertion hole or according elastic body from the top view of the seat surface of discrimination of paid numeric visualized, embodying to improve to workability in and out (increase or decrease) the spring member according simultaneously.

In addition, third strut or fourth pillar (elastic body) of the upper end below to circumferentially provided a seat joint according to the outer wall Rutotomoni, butt the projection of the upper or lower or outer walls of the upper and lower both the seat joint according setting the fact, since the vertically struts container comprising a projection wobbled groove and post fitting hole having a friction surface arrangement corresponding to such a protrusion on the lower side of the seat opening, third strut according or a four-post when the top to the post fitting hole of the (elastic body) is fitted on installing the seat, friction surfaces of the upper portion of the seat joint according than once in a predetermined range in the horizontal direction while contacting It is supported movably.
Further, the third strut or fourth advantage of that it can detachably attached to a seat according a tower according.
In the configuration according, anti elastic restoring force generated when returning to the original position against the tilt toward the circumferential direction of the third strut or fourth strut according to the cornering movement, the protrusion is deformed according to the time of twisting motion Thus, the elastic restoring force generated when restoring the original shape can be roughly classified.

Incidentally, if according projections made of material having elasticity such as rubber, the elastic restoring force included as a characteristic in the third strut or fourth pillar (elastic body) body according to invert the seat according to the time of twisting motion, according projections The elastic restoring force that works at the time of deformation is added.
Therefore, the reinforcement and training of the user's rectus abdominis and external abdominal oblique muscles and latissimus dorsi muscles are more efficient than when the twist exercise is performed using the chair according to claim 1 or 2. To be promoted.

Further, a regulation having a function of limiting a range and a tilt amount (tilt angle) in which the first and third support columns or the second and fourth support columns that follow the movement of the user seated on the seat turn in the circumferential direction. When the first and third columns or the second and fourth columns are deformed due to the weight of the user due to the weight of the user, the columns can be twisted to the left and right, and the front and rear or left and right or The function of linearly moving in the oblique direction and the function of rotating while tilting in the circumferential direction were maintained, and at the same time, the safety of the user during exercise was greatly improved.

Therefore, the first and third support post or the second-fourth, the longitudinal crosspieces and chair can exercise constructed by using the restriction means is not limited to athletic, used in a state where the user substantially stationary Combines usefulness and versatility that can be used for various purposes such as office and dining.

The third strut consisting of a plurality of projections 3v was horizontally provided on the outer wall 31 of the moderately below the upper, fixed to the outer wall 31 of moderate downward from the projections 3v, or a seat junction 3b which is circumferentially provided with integrated There is also a measure that uses the third class (except 3/9) in the first embodiment or a modification related thereto.
In addition, in 1st Embodiment introduce | transduced below or its modification, the leg part 2 * 2/1 of the same structure and the same shape is called the leg part 2, and the seat 5 * 5/1 is also called the seat 5, Similarly, the seat surfaces 5c and 5c / 1 are referred to as seat surfaces 5c, and the seat openings 5a and 5a / 1 penetrating in the same inner dimensions are referred to as seat openings 5a.

As a first example of a strut type 3 used in the illustrated embodiment of the chair 1 it can exercise from FIG 1 illustrates four, first strut 3/1 projecting from the seat junction 3b at the upper end of the first strut 3 Figure 5 is shown below.
Further, different as an example of the structure of a number opened annularly provided around to Rutotomoni upper end of the gap between the outer wall 31 and inner wall 32 of the elastic body 30 formed into a cylindrical shape the aperture 3a / 1 spring insertion hole 3a When first strut 3/2 consisting of a seat joint 3b projecting from the upper end is shown below Figure 19.

In FIG. 5 or 17, a schematic perspective view of an elastic member 3d / 1 formed in the shape of a vertically long cylindrical bar for placement (storing) in the opening 3a / 1 (spring insertion hole 3a) is introduced. .
However, the shape of the elastic member 3d class is not limited to a cylindrical rod shape, for example, elastic formed in rod-like elastic members 3d / 2 or prismatic formed into a rod shape of a triangular prism shown in FIG. 11 lower part 3d / as 3, but regardless of the shape as long as the outer dimensions and the overall length using material rubber can out from the formation to Rutotomoni opening 3a / 1 or open opening 3z the elongated bar shape.
Incidentally, a coil spring 3d / 4 (not shown) having an outer dimension and a full length that can be easily inserted and removed from the opening 3a / 1 or the opening 3z provided in the spring insertion hole 3a is used as a substitute for the elastic members 3d. There is a way to do this.

The 1st support | pillar 3 and 3 / 1-3 / 5 or 3/7 or 3/10 or the 1st support | pillar 3 / x and 3 / y are the points made using the rubber-type material rich in elasticity. the spring insertion hole 3a or from the point of leaf spring insertion hole 3s is disposed therein, and a twisting motion twisting to the right and left lumbar around an axis of these struts in a posture of being seated on the seat 5, the body in the circumferential direction A swivel motion (circular motion) that draws various circumferences in a posture tilted outward can be performed freely.
Therefore, in the case of the 1st support | pillar 3 and 3 / 1-3 / 5 or 3/7 or 3/10 , the spring material stored in the spring insertion hole 3a resists tilting (deformation) in all directions. It is preferable to select the elastic member 3d / 1 formed in the shape of a cylindrical bar using a rubber-based material in which the elastic restoring force acts similarly.
Further, loosely fitted state the spring member to Osame置the leaf spring insertion hole 3s was provided inside the first support 3 / x and 3 / y, which is Osame置the leaf spring insertion hole 3s shown in FIG. 2 1 It is preferable to select a leaf spring 3t / 1 made of a rubber-based material that is made into a long flat plate shape.

In the illustrated example of the seat 5 introduced in the first embodiment, a substantially circular seat opening 5a is provided in the vicinity of the center of the seat surface 5c corresponding to the position where the user is seated.
In this structure, when setting the elastic member 3d / 1~3d / 3 or coil spring 3d / 4 or leaf spring 3t or 3t / 1,, the entire length of slightly about protrudes from the opening 3a / 1 or 3a / 3, FIG. 5 A seat joint 3b projects from the upper end of the first support column 3/1 shown below, and is raised above the adhesive surface 6z, so that the opening 3a / 1 or 3a / 3 and the seat opening 5a (seat surface 5c It is preferable to provide a space in the distance from the back surface of).
In this case, the elastic member 3 such or coil spring 3d / 4 or leaf spring 3t or 3t / 1 while Osame置the spring insertion hole 3a or plate spring insertion hole 3s, upper end opening 3a / 1 or 3a, / 3 even Karakara slightly protruding entire length, can be addressed if the first strut 3/1 shown in the illustrated example of FIG. 5 below which projects the seat junction 3b at the upper end.
By the way, there is also a measure that substitutes by providing the same structure as the first support column 3/1 by projecting the seat joint portion 3b at the upper end of the other first support column 3 type.

More specifically, the sets from the upper end of the first post 3 such a projection length of the seat junction 3b to 30mm about length (height), first a first post 3 shown in FIG. 5 above in FIG lower As shown in the perspective view of the upper part of the first column 3/1, it is desirable that the lower side of the seat joint 3b and the upper side of the outer wall 31 of the first column 3 are integrally molded.
In such structure, the first strut 3/2 (diagram first strut 3/1, or a seat junction 3b projecting from the top end projecting from the upper end of the seat junction 3b shown in FIGS. 2-4 and 6 19) (see below), there is no problem if it is securely joined and connected to the back surface of the seat 5 directly below the seat opening 5a.

In response to such a structure, the elastic member 3d / 1 to 3d / 3 or the coil spring 3d / 4 , or the total length of the leaf springs 3t and 3t / 1, with one end in contact with the end point 4k, the other end is a spring insertion hole. opening 3a / 1 opened at the upper end of 3a, or alternatively consists of the opening 3a / 3, which opened on an upper end of the leaf spring insertion hole 3s generally possible to set the length that protrudes approximately 10 mm to 20 mm.
Thereby, workability at the time of picking up the upper end of the elastic member 3d or the coil spring 3d / 4 projecting from the opening 3a / 1 , or the leaf springs 3t and 3t / 1 from the seat opening 5a is improved.
According to the structure, the elastic member 3d acids or coil spring 3d / 4 or the seat opening 5a by applying differently colored from the color of the upper end of the first post 3 such across the plate spring 3t · 3t / 1, Visibility is improved, and convenience in predicting an elastic restoring force that works against deformation of the first support column 3 is improved.
In other embodiments described below or modifications related thereto, the seat joint portion 3b having the same shape and the same length, and the other end being approximately 10 mm to 20 mm from the opening 3a / 1 with one end in contact with the end point 4k. some measures to adopt the entire length of the elastic member 3d / 1~3d / 3 or coil spring 3d / 4 to the extent projected, or a structure using a plate spring 3t · 3t / 1 in common.

According In the configuration, in a state where one end of the elastic member 3d acids or coil spring 3d / 4 or leaf spring 3t such, in contact with the end point 3k, the elastic member 3d acids or coil springs protruding about 10mm~20mm from the opening 3a / 1 3d / 4 or other end of the leaf spring 3t such, is, can not become a situation that protrudes from the seat opening 5a / 2 which is formed through the seat opening 5a or substantially square shape shown in Figure 12 below.
Thus, the user when sitting on the seat 5, the elastic member 3d acids or coil spring 3d / 4 or the upper end of the leaf spring 3t such that or stuck in the buttocks of the user, it does not cause trouble to or hit.
Therefore, there is no object that touches the buttocks when the user sits on the seating surface 5c and performs a twisting motion or a three-dimensional turning motion, so there is no discomfort.

Further, as an advantage of the structure in which the seat joint portion 3b protrudes from the upper end of the first support column 3, the elastic member 3d or the coil spring 3d / which is set to a length that protrudes approximately 10 mm to 20 mm from the opening 3a / 1. 4, or visibility when checking in a top view the arrangement and pay the numeric of the leaf spring 3t such from the seat opening 5a or 5a / 2 becomes better.
Further, the work to increase or decrease and out of these elastic members 3d acids or coil spring 3d / 4, or leaf spring 3t such from the opening 3a / 1 or 3a / 3 is facilitated.
Therefore, the elastic member 3 such or coil spring 3d / 4, or because the leaf spring 3t such can easily change out to placement or paid numeric from the opening 3a / 1 or 3a / 3, the operation of the first post 3 such Workability when changing or adjusting the elastic restoring force acting against the direction (deformation) is improved.

Incidentally, it disposed around the annular gap between the outer wall 31 and inner wall 32 of the elastic body 30 formed into a cylindrical shape and internally provided with a number of spring insertion hole 3a, which opened the opening 3a / 1 to the upper end 19 In the first support column 3/2 shown below, the opening 3z (see the upper part of FIG. 32) having an inner dimension equivalent to the opening 3a / 1 is formed on the outer wall 31 moderately below the upper end of the elastic body 30 with the spring insertion hole 3a. In addition to the establishment of the same number, there is a measure to pierce the opening 3z toward the spring insertion hole 3a.
Further, the opening 3a / 1, which opened at the upper end, the first strut such that both open ports 3z which opened on the outer wall 31 of the lower facilities generally protrudes about 10mm~20mm from the opening 3a / 1 or 3a / 3 If you Osame置set to the length elastic members 3d acids or coil spring 3d / 4, or leaf spring 3t such from opening port 3z, as in the illustrated example of the first strut 3/10 indicated above in FIG. 32 a state where the end portion of the elastic member 3d / 1 protrudes from opening port 3z.
In such a structure, the elastic member 3 or the coil spring 3d / 4 , or the leaf spring 3t, which is placed in the spring insertion hole 3a, can be taken in and out from either the opening 3a / 1 or the opening 3z.

More specifically, as shown in the illustrated example of the first strut 3/10 in Figure 32 upward, the spring insertion hole 3a while being protruded end portion of the elastic member 3 such or coil spring 3d / 4 from opening port 3z from being able Osame置, the elastic restoring force against the curved towards the circumferential direction of the first strut 3/2 by increasing or decreasing these paid numeric (refraction) variable, or when adjusting, the user The elastic member 3 or the coil spring 3d / 4 can be taken in and out in a posture in which the seat 5 is seated on the seating surface 5c.
For this reason, it is not always necessary to penetrate the seat opening 5a, so that the production cost can be reduced by simplifying the manufacturing process of the seat 5.
Incidentally, the opening 3a / 1 or 3a / 3 and both the opening port 3z which opened the outer wall 31 is provided in the first post 3 such, the elastic member 3 such or coil spring 3d / 4 opened in the upper end or the leaf spring, When the 3t class is placed from the opening 3z, the upper part (above the opening 3z) of the spring insertion hole 3a or the leaf spring insertion hole 3s becomes a space.
In a state of, from being de-energized only on the first post 3 type (upward from opening port 3z), it is easily deformed by twisted to the left and right. Therefore, it is suitable for conducting twist exercises.

For example, when using the chair 1 that allows a user with heavy weight to perform the exercise of the structure, the elastic member 3d / 1-3d / 3 or the coil spring 3d that is made slightly longer than the entire length of the spring insertion hole 3a. / 4 is placed in the most part of the spring insertion hole 3a from the opening 3a / 1, thereby reducing the amount of space of the first column 3 (the number of empty spring insertion holes 3a is small).
In such a state, the elastic restoring force acting against the deformation of the first support column 3 can be obtained by confirming the arrangement and the number of placement of the elastic members 3d or the coil springs 3d / 4 from the seat opening 5a in a top view. Can be predicted roughly.
Thus, exercise intensity unspecified users required for each time, or the elastic restoring force acting on the first post 3 such by adjusting the pay registered number of the elastic members 3d acids or coil spring 3d / 4 depending on the conditions relating to the physical It becomes possible to adjust in advance.

Specifically, in a state where the elastic member 3d or the coil spring 3d / 4 is previously placed in most of the spring insertion hole 3a, the elastic member 3d or the coil spring is applied to the elastic restoring force of the first support column 3 main body. Since the elastic restoring force possessed by 3d / 4 is added, the amount of deformation of these columns flattening in the lateral direction can be minimized by applying a weight such as the weight of the user.
In such a state, since the elastic restoring force against the deformation in the left and right twist direction, the up and down direction, and the circumferential direction of the first support column 3 is enhanced, a functional due to weighting such as the weight of the user is caused. Can be avoided in advance.

Further, when the first column 3 connected to the rear surface of the seat 5 is the first column 3/7 formed in a substantially prismatic shape shown in the upper part of FIG. 19, the seat opening 5a is not only circular, but also FIG. The seat opening 5a / 2 having a substantially rectangular shape indicated by reference numerals 13 and 13 , or a seat opening (not shown) penetrating in a different shape, the inner dimension of the seat opening 5a or 5a / 2 or the first dimension Regardless of the shape of the column 3 or the like, it is preferable to set the outer dimension of the seat joint 3b> the inner dimension of the seat opening 5a within a range where the opening 3a / 1 or 3a / 3 can be seen.
In this case, since the adhesive surface at the time of fixing the upper end of the seat junction 3b on the back of the seat surface 5c directly below the seat opening 5a or 5a / 2 is satisfied, reliable seating 5 and the first post 3 such Bonding is realized.

Receiving structure has an inner dimension <outer dimensions of the seat opening 5a or 5a / 2, the first strut 3/1 projecting from the seat junction 3b having a protrusion length of about 30mm on the upper end view according 5 is shown below.
In the illustrated example of the first support column 3/1 or 3/2 shown in the lower part of FIG. 5 or the lower part of FIG. 19, a seat joint 3b projects from the upper end of these supports and the joint surface (the upper end of the seat joint 3b) ) Is sufficiently secured so that it cannot be removed from the back surface of the seat surface 5c directly below the seat opening 5a or 5a / 2 or other seat opening 5 (not shown). Thus, it is possible to select an appropriate joining means such as the one and securely fix it.

Further, on the rear surface of the seat 5, 5/1 made lightweight to ensure the strength assumes using fiber-based materials, such as glass fiber or carbon fiber (just below the seat opening 5a), projecting about 30mm in the structure for connecting the first strut 3/1 or 3/2 projecting from the upper end of the seat junction 3b having a length, an elastic member made in 10mm~20mm about long than the overall length of the spring insertion hole 3a 3d / 1 to 3d / 3 or the coil spring 3d / 4 does not protrude from the seat opening 5a or 5a / 2.
In such structure, since it can take an accurate joining means when securing the seat junction 3b projecting from the first upper end of the post 3/1 or 3/2 to the rear surface of the seat surface 5c directly below the seat opening 5a The user who is seated on the seating surface 5c is concerned that the first support column 3/1 or 3/2 may be removed from the rear surface of the seat 5 when performing a twisting motion or a turning motion using a large circumference. There is no force.

In such structure, 3a / 3, which opened in the upper end of the opening 3a / 1 or a leaf spring insertion hole 3s, which opened on an upper end of the spring insertion hole 3a that is provided inside the first support 3 such that, 12 or 13 that it can be visually recognized from the seat opening 5a or 5a / 2 shows a schematic top view of the seat surface 5c · 5c / 1 main part of the lower, compared to the full length of the spring insertion hole 3a or plate spring insertion hole 3s, 10 mm to 20 mm Since the elastic members 3d or coil springs 3d / 4 or leaf springs 3t that are made so long can be used, it is easy to visually arrange them from above the seat opening 5a or 5a / 2. The advantage is that it can be confirmed.
In this case, when changing the number of the elastic members 3d, the coil springs 3d / 4 , or the leaf springs 3t and changing the number of stored members, it is easy for the user to take a posture to float at least from the seating surface 5c. It becomes possible to do.

In the embodiment introduced above and the modifications related thereto, the inner dimension of the seat opening 5a or 5a / 2 <the cross section of the first support column 3 can be provided, so that the seat opening 5a of the first support column 3 or Protrusion from 5a / 2 is prevented, and at the same time , the upper end of the first support column 3 is bonded to the back surface directly below the seat opening 5a or 5a / 2 by bonding means or the like, or the cross section of the first support column 3 The upper end (upper surface) of the seat joint portion 3b is bonded to the back surface immediately below the seat opening 5a or 5a / 2 after securing a joint surface by projecting the upper end of the seat joint portion 3b having a larger size and a donut shape. It has been dealt with by one of the measures to connect by fixing means such as.

However, the first support post 3/7 (see the upper part of FIG. 19) has an opening 3a / 1 at the upper end, a plurality of spring insertion holes 3a are provided therein , is formed in a prismatic shape, and the seat joint 3b is not provided at the upper end. ), Or in the structure in which the first support columns 3 are formed in a column shape different from the illustrated example and the seat joint portion 3b does not protrude from the upper end thereof, the cross section of the support columns> the seat opening 5a or 5a There is also a measure to deal with by setting the inner dimension of / 2.
In the first column 3 or the seat opening 5a or 5a / 2 in which such a measure is taken, these columns are formed in a column shape different from the illustrated example, and the seat opening 5a or 5a / 2 has a shape different from the illustrated example. can also, gymnastics shown in Figure 1 of the structure you joined adhesive surface provided at the upper end edge of the first support 3 6z (see FIG. 5 above) on the back just below the seat opening 5a in the case of formed through the The function similar to the example of illustration of the chair 1 is show | played.

That is, as compared with the inner dimensions of the seat opening 5a or 5a / 2, or the seat junction 3b is enlarged cross section of the first support 3 such that no projecting from the upper end, the seat junction 3b is not projecting from the upper end Compared with the cross section of the first support column 3 (not shown), the first support column 3 is reduced from the seat opening 5a or 5a / 2 by reducing the penetration range of the seat opening 5a or 5a / 2. Protruding of the kind can be prevented.
Further, as compared with the inner dimensions of the seat opening 5a or 5a / 2, an enlarged outer dimensions of the cross section of the first support 3 such, the measures for avoiding the protrusion of these posts, the first post 3 such upper end Since the area of the adhesive portion 6z indicated by the oblique lines in the upper part of FIG. It becomes possible.
In this case, than the length of the elastic member 3d / 1~3d / 3 or coil spring 3d / 4 or leaf spring 3t or 3/1, protrudes from the spring insertion hole 3a or plate spring insertion hole 3s, seating surface 5c by instal the seat 5 so that the thickness of above, some measures to avoid projecting from the elastic member 3d acids or seat opening 5a of the plate spring 3t such.

Subsequently, a plurality of vertical beam members 6 fitted in the vertical beam member joining holes 6/1 provided in a plurality of positions on the leg 2 and fixed inside the vertical beam members 6 above. In addition, a circular restriction frame 6a / 1 surrounding the periphery of the outer wall 31 of the first support column 3 (see FIG. 1) or the first support column 3/2 (see the lower part of FIG. 19) , a plurality of horizontal rail members 6c, and a control frame function chairs 1 can exercise indicated in the illustrated example of FIG. 3 or FIG. 20 which is constructed using a restriction means 6a consisting of an outer frame 6d having a large diameter (see Fig. 3, 4 and 20) exhibited than 6a / 1 The operational effects of will be described below.

3 and 4, the regulating means 6a is welded to a plurality of horizontal bars 6c in which the inner side and one end of a circular outer frame 6d are laterally arranged by welding, and the other ends of these horizontal bars 6c. made from the outer diameter> made in small diameter circular regulating frame 6a / 1 Metropolitan of Rutotomoni outer frame 6d.
In such a structure, the shape of the outer frame 6d and the regulation frame 6a / 1 is not limited to a circular shape, and the first support column 3 (partially not shown) introduced in the first embodiment, or hereinafter, FIG. 24 to FIG. 29 and FIG. If the shape surrounds the periphery of the outer wall 31 of the third support column 3/6 or 3/8 or the fourth support column 3n / 6 or 3n / 7 shown in the illustrated example of 30, there is no structural problem.

By the way, using the embodiment of the chair 1 that can be exercised without the restriction means 6a as in the illustrated example introduced in FIG. In this case, as depicted by the broken line in FIG. 2, the first support column 3 including the seat 5 tilts outward in the circumferential direction with the start point 3w slightly above the joint between the leg 2 and the first support column 3 as the main axis. Rotate.
Thus, in the configuration using the first post 3 such as restricting means 6a the illustrated example or other attaching a regulating means 6a shown in Figure 3, 4, 6 or FIG. 20 (not shown), sometimes the first post 3 Since the outer wall 31 is swung (turned) while being in contact with the inner side of the regulation frame 6a / 1 in a state inclined to the outer side in the circumferential direction, in order to realize smoother turning of the first support column 3 The restriction frame 6a / 1 is preferably formed in a circular shape.

In the illustrated example shown in FIGS. 3, 4, or 6, the outer frame 6 d, the crosspiece 6 c, and the regulation frame 6 a / 1 are made of metal materials and are joined to each other by welding.
FIG The 3 or illustrated example shown in 4, a plurality of longitudinal crosspieces 6 made into a rod of a material of the metal-based, vertical hole made in the dimension within which緊合these conditions the longitudinal crosspieces 6 was inserted Jo vertical crosspieces are recessed at a plurality of locations on the joining hole 6/1 legs 2, these longitudinal crosspieces joining hole 6/1 are fitted the same number of longitudinal crosspieces 6, these An outer frame 6d is fixed on the upper inner side of the vertical beam member 6, and a plurality of horizontal beam members 6c are installed on the inner side of the outer frame 6d. 6a / 1 is fixed.
The material of the vertical beam 6, the outer frame 6d, the horizontal beam 6c, and the restriction frame 6a / 1 is not limited to metal, but other materials can be used in the same structure as long as they are sturdy. is there.
Incidentally, it is preferable that the vertical beam member 6 and the restricting means 6a having such a structure are commonly used in other embodiments described below or modifications related thereto. In that case, the safety of the user who performs the turning motion which draws the circumference of various forms with the posture seated on the seat 5 is improved.

Further, in the configuration using the vertical crosspieces 6 restriction means 6a, the vertical direction of the longitudinal crosspieces 6 an engagement portion 6d made in the outer frame 6d and disengageably be engaged shape shown in the illustrated example of FIG. 20 multistage fixed to Rukoto of is desirable.
In such a structure, when the user seated on the seating surface 5c performs a turning motion that draws various circumferences, the outer frame of the regulating means 6a provided with the regulating frame 6a / 1 having a wide inner space shown in the upper part of FIG. If is engaged and 6d the engaging portion 6d which is fixed to the upper longitudinal crosspieces 6, third strut described in the first post 3 such or below that depicted in chain line 2 wire 3 points in 3 / As the tilting (curvature / inclination) in the circumferential direction of 6 or the fourth support column 3n / 6 increases, the movable point x indicated by the two-dot chain arrow key line connector in the figure is in the direction of the leg 2, that is, downward. Moving.

Contrary, if allowed to engaged the outer frame 6d of the restricting means 6a for narrow restriction frame 6a / 1 of the frame in the space provided in the engaging portion 6d which is fixed above the longitudinal crosspieces 6, the diagram of FIG 20 below In the example shown, tilting (curving / inclination) in the circumferential direction of the first support column 3 or the third support column 3/6 or the fourth support column 3n / 6 depicted by a two-line, three-dot chain line is reduced.
In this case, the movable point x indicated by the two-dot chain line arrow key line connector in the figure moves toward the seat 5, that is, upward.
Therefore, when is engaged to the outer frame 6d the engaging portion 6d which is fixed at the same height, the regulating means 6a wide regulation frame 6a / 1 of the frame space is provided, the first post 3 such or the The angle at which the three struts 3/6 or the fourth strut 3n / 6 tilts (tilts) in the circumferential direction increases, and the turning area (turning range) increases.
On the other hand, in the restriction means 6a provided with the restriction frame 6a / 1 having a narrow inner space, the angle at which the first support column 3 or the third support column 3/6 or the fourth support column 3n / 6 tilts (inclines) in the circumferential direction. And the turning range becomes narrower.

Subsequently, the upper surface of the seat junction 3b projecting from the upper end of the first post 3 such, the seat 5 first post 3 such a back outside measures of fixing by means such as adhesion (seat opening 5a) A structure for connecting the upper part of the seat and the back surface of the seat 5 (seat opening 5a) will be described below.
By opening equivalent as compared to in the seat opening 5a mentioned or 5a / 2 of an inner diameter, or more, or the opening of the inner dimension that is expanded slightly to the upper end, it fitted the outer wall 31 of the first support 3 such opened post fitting hole 3c / 6 made in the internal dimensions at the lower end, Katachi設inside an inverted flared strut container 3c spread upward in the space directly below the seat opening 5a or integrated, A schematic perspective view of the seat 5 installed in FIG.

In view of such a structure, a schematic perspective view of the main part of the first support column 3/3 in which the seat joint 3b is fixedly or integrally provided around the outer wall 31 moderately below from the upper end of the first support column 3 is shown in the lower part of FIG. It is shown.
As a variant, (see Figure 19 below) first strut 3/2 projecting from the seat junction 3b at the upper end, or other first post 3 such a first strut 3/3 and nestled in the structure There is also a plan to substitute.
Further, fixing the seat joint 3b in the outer wall 31 of moderate downward from the upper end of the first strut 3/7 formed in a prismatic shape shown in Figure 19 upward, or in circumferentially provided with integral (not shown) first There is also a measure to substitute the column 3/3. In this case, there is also a measure to form a column insertion hole 3c / 6 opened at the lower end of the column container 3c into a shape and an internal size that can be fitted to the outer wall 31 of the first column 3/7.

Specifically, when the upper portion of the first support column 3/3 is inserted from the lower side of the support column insertion hole 3c / 6 and the lower end of the support column insertion hole 3c / 6 and the upper end (upper surface) of the seat joint portion 3b contact each other. in the seat joint 3b as the upper end of the first strut 3/3 is located is circumferentially provided with fixed to the outer wall 31, or integrated into a generally 30~50mm about the lower strut container in 3c from the seat opening 5a ing.
In such a structure, the upper end of the seat joint 3b and the lower end of the column insertion hole 3c / 6 are indispensable in order to prevent slipping when the seat 5 that follows the user's movement during the twisting motion is rotated. .

On the other hand, a structure in which the first support column 3 and the seat 5 are configured to be detachable while preventing the idling of the seat 5 around the first support column 3 when rotating is described below.
In that case, the seat 5 that Gu設strut container 3c directly below the seat opening 5a shown above in FIG. 14 (the back surface of the seat surface 5c), beyond a predetermined angle towards the rotation direction (left-right) It is desirable to attach a structure for restricting the rotation of both the support post container 3c and the first support post 3/3 shown in the lower part of the figure.
As an example of the structure of, the outer wall 31 of the spacing between the seat junction 3b top surface from the upper end of the first strut 3/3 introduced in the lower part of FIG. 14, a plurality of protrusions 3 v a constant interval is formed in a plate shape FIG. 16 shows a schematic perspective view of the main part of the third support column 3/6 that is placed horizontally with a gap therebetween.
Further, by opening the post fitting hole 3c / 6 of inner dimension loosely fitted in a state over the outer wall 31 of the third strut 3/6 top to bottom, with corresponding to the arrangement of the projections 3 v, the projections 3 v laterally set toward the inner wall surface 3c / 2 inward projections swaying 3m · 3m · 3m intervals loosely fitted in a state of fitted is post container 3c which apparently shown in FIG. 14 above A schematic perspective view of the seat 5 in which the support container 3c / 1 having the same shape as that of the seat 5 is provided immediately below the seat opening 5a is shown in the upper part of FIG. By the way, there is also a measure to substitute the first support column 3 with the same structure as the third support column 3/6.

Structure strut container 3c / 1 is 16 above the illustrated directly below the seat opening 5a shown in Example (seating surface 5c of the back) cylindrical inner wall surface and vertically to 3c / 2 and (two-dot chain line) , in an arrangement corresponding to the arrangement of the projections 3 v (dashed line), the inner and the horizontal set from the wall 3c / 2 inward with separating a predetermined distance, a plurality of sets of which is formed in a flat plate shape in a pair on the left and right a projection swaying 3m (two-dot chain line), a post fitting hole 3c / 6 Metropolitan which opened at the lower end of the inner wall surface 3c / 2.
By the way, in the case of the configuration using the third cylindrical pillar 3/9 shown in the lower part of FIG. 17 provided in the same structure as the third pillar 3/6 introduced in the lower part of FIG. 16 and the pillar container 3c / 1, 3 with over the outer wall 31 of the strut 3/9 top, there is a plan to establish a post fitting hole 3c / 6 made in the rotatable shapes and inner dimensions at the lower end of the column container 3c / 1.
There are also measures to adopt a first post 3 such that nestled third strut 3/6 in the same structure, the structure using the seat 5 that Gu設directly below the seat opening 5a struts container 3c / 1 .
In the illustrated example, both the protrusion 3v and the seat joint 3b are made of a rubber-based material and are formed integrally with the outer wall 31, so that the seat 5 or 5/1 and the column container 3c or the column container 3c are formed. / 1 or strut container 3c / 2 · 3c / 3 · 3c / 4 to introduce below is Katachi設by both using the hard material.

On the other hand, a cylindrical elastic body 30, and a space 3h portrait provided inside of the inner wall 32, disposed around the gap between the outer wall 31 and inner wall 32, a number of spring insert which opened the opening 3a / 1 to the upper end and the hole 3a, the first strut 3/5 Figure 15 above the enlarged partial perspective view and a plurality of protrusions 3 v which laterally set at regular intervals on the outer wall 31 of moderate downward from the upper end of the elastic body 30 It is shown.
On the other hand, in the lower part of FIG. 15, there is an interval at which rotation within a certain range is possible with the projections 3 v horizontally installed on the outer wall 31 moderately below from the upper end of the first support column 3/5. In the arrangement in which these protrusions 3 v are fitted, a pair of protrusion rocking grooves 3 m on the left and right sides that are set in the same number as the protrusions 3 v toward the inside of the inner wall surface 3 c / 2 are driven by the rotation of the seat 5. these projections swaying 3m each projection 3 v to the right and left inner wall surfaces are virtual top plan view as seen how the deformed like an arch from the upper surface of the seat opening 5a in contact is shown.
Incidentally, in the illustrated example, a shielding wall is provided above each of the protrusion swing grooves 3m and 3m. (Not shown)

In the following, the projection 3 v and the seat joint 3b with using materials of rubber in the third column 3 such that Gu設mainly third strut 3/6 was introduced in the lower part of FIG. 16 or, a projection 3 v was horizontally provided at three positions on the outer wall 31 of the first strut 3/5 indicated above in FIG. 15, and the seat joint 3b which is provided around the outer wall 31 of the downwardly from the projections 3 v, screw 3f a third strut 3/8 shown in FIG. 17 which is constituted by the will be described with reference to the accompanying drawings for the embodiment using the pole container 3c / 1.

17 is a partially enlarged perspective view of the upper main portion of the third column 3/8, and an elastic body formed in a substantially rectangular tube shape having a vertically long space 3h at the center. a plurality of spring insert holes 3a, which opened the opening 3a / 1 at the upper end as well as circumferentially provided on the interval between 30/2 of the outer wall 31 and inner wall 32, fixed to the outer wall 31 of moderate downward from the upper end of the elastic member 30/2 a projection 3 v was horizontally provided at three positions in a state spaced a third strut 3/9 upper main part composed of a seat joint 3b which is provided around the outer wall 31 of moderate downward from the projections 3 v A partially enlarged perspective view is shown.
In the illustrated example, the elastic body 30, the protrusion 3 v, and the seat joint 3 b are both made of a rubber material, and the protrusion 3 v and the seat joint 3 b are formed integrally with the outer wall 31. ing.

For example, the post fitting hole 3c / 6, which opened in the lower end of the column container 3c / 1 to vertically directly below the seat opening 5a (the rear surface of the seat surface 5c), the third strut 3/8 (FIG. 17 upper reference ) Or 3/6 (refer to the lower part of FIG. 16), assuming that a user who is seated on the seat 5 in a state of being fitted and attached to the ground and has a foot on the ground alternately twists right and left. .
In this case, as a result of each of the protrusion rocking grooves 3m being driven in the rotation direction of the user (seat 5), the third support column 3/8 or 3 is finally attached to either the left or right inner wall surface of each protrusion rocking groove 3m. / 6 at the same time each horizontally provided with projections 3 v on the outer wall 31 abuts the deformed state which is curved like a bow as depicted progressively by a broken line in FIG. 15 below.
In such a state, the drag (stress and elastic restoring force) that acts when returning to the original shape is applied due to the inherent characteristics (depending on the thickness and width) of each protrusion 3 v made of a rubber-based material. Therefore, the elastic restoring force acting when the protrusions 3 v , 3 v , 3 v are deformed reversely rotates the seat 5 from the protrusion rocking grooves 3 m, 3 m, 3 m through the inner wall surface 3 c / 2 (post support container 3 c / 1). This is reflected in the user as the stress to be generated.

Specifically, the post container 3c / 1 was introduced in Figure 16 above a seat 5 which is Gu設directly below the seat opening 5a, in the configuration using the third strut 3/6 or 3/8, the seating face 5c When the seated user performs a twisting motion, when the seat 5 is rotated clockwise, each protrusion swing groove 3m is rotated in the right direction following the user's operation.
The frictional surface 3c / 7 abutting state according except resistance due to friction with the upper end of the seat junction 3b, until each of the projections 3 v on the inner wall surface of each protrusion swaying groove 3m left abuts, these projections 3 v and the spring inserting elastic member 3d in the hole 3a is Osame置acids or coil spring 3d / 4 and the third strut 3/6 body or 3/8 elastic restoring force is the nature of the body, (stress-drag) Does not work in earnest.

However, the inner wall surface of each protrusion swaying 3m left driven in accordance with the progress of the right rotation of the user sitting on the seat surface 5c, when the protrusions 3 v began to deform in contact with, the projections 3 Since the elastic restoring force generated when v returns to the original shape starts to act, there is a slight reverse rotation of the seat 5 counterclockwise via the protrusion rocking groove 3m and the inner wall surface 3c / 2 (the container 3c / 1). A drag force (an elastic restoring force of the protrusion 3 v ) is generated.
In a state according respectively to amplify as toward the same direction (clockwise) deformation of each projection 3 v in contact with the inner wall surface of each projection swaying 3m left to follow the further progression of the user's operation increases in addition to the drag acting on the projection 3 v (stress-elastic restoring force), the projections were shaped set integrally molded with the outer wall 31 3 v, 3 v, 3 v outer wall 31 to the third strut 3/6 or 3 / 8 main-elastic member 3d acids, or that propagates in the order of the coil spring 3d / 4.
Therefore, the elastic restoring force against the elastic member 3d such that Osame置the third strut 3/6 or 3/8 body and the spring inserting hole 3a, or the nature of coil spring 3d / 4 deformation is applied gradually.
In this case, if each of the projections 3 v reaches the limit of the deformation, and at the same time抜力when the user rotates the seat 5 toward the same direction reaches the arduous conditions, each of the projections 3 v and The drag (stress / elastic restoring force) acting on the third support column 3/6 or 3/8 and the elastic member 3d , or the coil spring 3d / 4 is released.
At this time, an elastic restoring force (drag) generated when the projections 3 v , 3 v , 3 v, the third support column 3/6 or 3/8, the elastic member 3d , or the coil spring 3d / 4 returns to the original shape is generated. reversing the seat 5 (in this case counterclockwise) to switch to urging force (stress), the inner wall surface 3c /. 5 to struts container via the projection 3 v · 3 v · 3 v ~ protrusions swaying 3m · 3m · 3m It propagates to the user sitting on the seat 5 through 3c / 1.

On the other hand, using the first support column 3 in which the protrusions 3 v , 3 v , 3 v and the seat joint 3 b are not provided, and the seat 5 in which the support container 3 c / 1 is not provided immediately below the seat opening 5 a. If using an embodiment of the chair 1 can exercise indicated by the example shown in FIG. 1 or 2 configured performed by repeated twisting motion, a plurality of spring insert holes 3a falls cavity with using materials of rubber in addition to the elastic restoring force included as an internal set characteristics to the first post 3, 3/1, 3/2, elastic you Osame置the spring insertion hole 3a members 3d / 1~3d / 3 or coil spring 3d / The influence which the effect by the effect | action of the elastic restoring force which 4 has on a user's body is demonstrated below.

In the case of the embodiment shown in the illustrated example of FIG. 1 or 2, in a state where the elastic member 3 or the coil spring 3d / 4 is not placed in the spring insertion hole 3a and the space occupies a large volume with respect to the volume of the first support column 3 or the like. Since the elastic restoring force that works against the deformation direction (twisting direction) of the first support column 3 during the twisting movement is minimized, the resistance force that acts when the first support column 3 returns to its original shape ( (Elastic restoring force / elastic restoring force) decreases.
In such a structure, since the upper ends of the first pillars 3/3/1 and 3/2 are directly fixed to the back surface of the seat 5, that is, directly below the seat opening 5a, the user sitting on the seat 5 When performing a turning motion or a twisting motion in the direction, the axis at the time of any motion is mainly borne by the vicinity of the starting point 3w located below these columns shown in FIGS.

On the other hand , in order to reinforce the elastic restoring force that works against the tilting direction of the first support pillars 3, 3/1, 3/2 during the turning motion, a large number of elastic members 3d are inserted into the many spring insertion holes 3a. / 1~3d / 3 or in the state where the Osame置coil spring 3d / 4, in addition to the elastic restoring force provided in the first support 3 or 3/1 or 3/2 body, elastic members 3d acids or coil springs, The elastic restoring force possessed by 3d / 4 is added.
In such a state, since the elastic restoring force that works against the behavior of the first column 3 (the user seated on the seat 5) is strengthened (biased), these columns are particularly difficult to twist in the left-right direction. Therefore, it is not suitable when a user with poor physical strength performs a twist exercise.
Further, when switching from the state to the twisting motion, the elastic member is opened from the opening 3a / 1 provided at the upper end of the spring insertion hole 3a in a state in which the user floats at least the waist (buttock) from the seat 5. 3d / 1~3d / 3, or time-consuming to retrieve the coil spring 3d / 4.

On the other hand, the projections 3 v · 3 v · 3 v shown in Figure 16 downward, the third strut 3/8 indicated above the third strut 3/6 or 17 composed of a seat joint 3b, above the 16 in the configuration using the seat 5 made of struts container 3c / 1 Tokyo Gu設directly below the seat surface opening 5a showing a number of elastic members in a number of spring insert holes 3a 3d / 1~3d / 3 or coils, seating spring 3d / 4 on the top of the third strut 3/6 or 3/8 that enhanced the elastic restoring force in a state in which Osame置, the post fitting hole 3c / 6 on the seat 5 attached to fitted on Assume that a user who has performed a twist exercise.

In this case, it is fitted on in a movable state seats 5 in the upper portion of the third strut 3/6 or 3/8 (post fitting hole 3c / 6) is within a range of lateral rotation direction, each projection swing since each of the projections 3 v in a limited area between the left and right inner walls of the groove 3m is loosely fitted, from each contact projections 3 v in left or right inner wall surface of each projection swaying 3m limit point of deformation, or up to the user at the time of抜力, each of the projections pivot grooves 3m are driven in the rotational direction of the user sitting on the seat surface 5c.
At this time, the seat 5 to each from the time activation of a user sitting on the seat surface 5c of the projection 3 v in left or right inner wall surface of each projection swaying groove 3m abuts, the strut fitting hole 3c / 6 Although there is resistance due to friction between the lower end (friction surface 40) and the upper surface of the seat joint portion 3b, it idles above the seat joint portion 3b.
Thus, the projections 3 v · 3 v · 3 v and elasticity are Osame置the third strut 3/6 or 3/8 body and spring insertion hole 3a members 3d / 1~3d / 3 or coil spring 3d / 4, In general, the elastic restoring force (drag) provided by the is not transmitted to users.

In such a state, the protrusions 3 v , 3 v , 3 v abut on the inner wall surfaces of the left and right of the protrusion swing grooves 3 m, 3 m, 3 m that follow the rotation direction of the seat 5 as the user rotates. deformed together begins (see Figure 15 below) limit point of deformation, or until the user at the time of抜力, integrated with Rutotomoni outer wall 31 made of a material of rubber acting in a direction opposite to the rotating direction of the seat 5 In addition to the elastic restoring force (stress / drag) inherent to the protrusions 3 v , 3 v , 3 v , the third support 3/6 or 3/8 and the elastic members 3d / 1 to 3d / 3 or the coil spring The elastic restoring force (stress / drag) of the 3d / 4 body acts.
Incidentally, the protrusions 3 v , 3 v , 3 v that are laterally integrated with a certain distance from the upper end of the first column 3 / x or 3 / y shown in the upper part of FIG. When, with these projections 3 v secured to the outer wall 31 of moderate downward from, or the first strut comprises a seat junction 3b which is circumferentially provided with integrated 3 / x or 3 / y (not shown), strut container 3c / 1 sits on the seat surface 5c constituted by a seat 5 having a case of performing the twisting motion, the third strut 3/6 or functions and effects according to the embodiment using a 3/8, as described above Has the same effect (stress / drag) as (stress / drag).

In such a structure, the restoring property (elastic restoring force) generated when the protrusions 3 v , 3 v , 3 v return to the original shape acts first, and at the same time, the column container 3 c via the protrusion swinging grooves 3 m, 3 m, 3 m. / 1 at the time of the propagation in (seat 5), switch to reverse the characteristics because the seat 5 of the rubber-based material (reverse) is to stress (elastic restoring force).
In this case, it has lateral set projection 3 v · 3 v · 3 v integrally molded with the outer wall 31, since it has internally provided a spring insertion hole 3a to the third strut class, user sitting on the seat surface 5c As the rotation (input) progresses, the elastic restoring force (stress and drag propagated by the input) and the elastic member 3d / placed in the spring insertion hole 3a are provided in the third column 3/6 or 3/8 main body. The elastic restoring force (stress / drag) provided in 1 to 3d / 3 or the coil spring 3d / 4 is gradually added.
In a state of stress acting on three of the outer wall 31 horizontally provided with projections 3 v and third strut 3/6 or 3/8 and the elastic member 3d acids, or during the deformation of the coil spring 3d / 4 (elastic restoring force) Synergize.
Accordingly, the elastic restoring force (stress / drag force) acting on each of the protrusions 3 v , 3 v , 3 v, the third support column 3/6 or 3/8 main body, and the elastic members 3d / 1 to 3d / 3 or the coil spring 3d / 4. ), The muscle strength of the user's rectus abdominis, external abdominal oblique, latissimus dorsi and gluteal muscles required for rotating the seat 5 is trained and reflected in strengthening these muscle groups.
In such a structure, the protrusion 3 v and the outer wall 31 are integrally formed using the same material as a measure for avoiding a problem that the protrusions 3 v , 3 v , 3 v are removed from the outer wall 31 due to an external force or torn. It is desirable to do.

On the other hand, the projections 3 v · 3 v · 3 v indicated below in FIG. 16, a third strut 3/8 indicated above the third strut 3/6 or 17 composed of a seat joint 3b, the bottom of FIG. 16 post container 3c / 1 in an embodiment using a seat 5 which is Gu設directly below the seat opening 5a and a small number of resilient members 3d / 1~3d / 3 or coil spring 3d / 4 the spring insertion hole, indicated by It is assumed that the user sitting on the seat 5 attached by attaching the column insertion hole 3c / 6 to the upper portion of the third column 3/6 or 3/8 in the state of being placed in 3a performs a twist exercise. .

In this case, between the projections swaying 3m · 3m · 3m each of the right and left inner wall which is provided inside the post container 3c / 1, since the projections 3 v · 3 v · 3 v is loosely fitted, at the time of twisting motion The elastic restoring force that works against the rotation direction of the user is mainly preferentially taken by the respective protrusions 3 v .
On the other hand, Stability acting upon against tilting (deformation and bending) toward the circumferential direction during turning motion to draw like-shaped oval or 8 returns to its original position, the third strut 3/6 or 3/8 in addition to the elastic restoring force the body originally has an elastic restoring force which the elastic member 3d / 1~3d / 3 was Osame置the spring insertion hole 3a or the coil spring 3d / 4, has plays.
As described above, in the illustrated example introduced in FIG. 16 , the third support column 3/6 or 3/8 resists deformation in the circumferential direction at the time of a swivel motion drawing an ellipse or a figure of 8 or the like. Stability acting upon return to the position, the elastic restoring force of these post body and a spring insertion hole 3a in Osame置is Ru elastic member 3d / 1~3d / 3 or coil spring 3d / 4 has plays.
Further, the drag (stress) acting during the twisting motion is integrated into the outer wall 31 so as to be integrated, except for the resistance caused by the friction between the upper surface of the seat joint 3b and the upper end of the column insertion hole 3c / 6 that occurs when the seat 5 rotates. Since the elastic restoring force of 3 v , 3 v , 3 v bears much, stability (elastic restoring force) acting against deformation that tilts (curves) in the circumferential direction and bilaterally It is possible to generally share the stability (elastic restoring force) that acts against deformation that twists.

Therefore, the elastic restoring force acting against deformation towards elasticity Osame置the spring insertion hole 3a members 3d / 1~3d / 3 or tilt direction by increasing the number of coil springs 3d / 4, (inclination direction) even third strut 3/6 or 3/8 which was adjusted to but to enhance the elastic restoring force against the deformation is screwed in the lateral direction when twisting movement (stress) is the projection 3 v · 3 v · 3 v is primarily responsible.
Thus, compared to you joining the upper end of the first post 3 such directly embodiments just below the back surface of the seat opening 5a shown in Figures 1-4, the seat 5 and the was vertically strut container 3c / 1 in embodiments using 3 post 3/6 or 3/8, when performing a twisting motion, the pay numeric removed elastic member 3d / 1~3d / 3, or a coil spring 3d / 4 from the spring insertion hole 3a reduces, labor Ru is de-energized the resilient restoring force acting on these struts is reduced.
On the other hand, when the protrusions 3 v , 3 v , 3 v come into contact with the inner wall surface on either the left or right of the protrusion rocking grooves 3 m, 3 m, 3 m and at the same time the third struts 3/6 or 3/8 start to deform. body, and a spring insertion hole 3a in Osame置the elastic member 3d / 1~3d / 3 or coil spring 3d / 4 to the original features elastic restoring force, (stress) starts joined slightly.
As the state progresses (increase in external force), the protrusions 3 v , 3 v , 3 v to the protrusion rocking grooves 3 m, 3 m, and 3 m (seat 5) to the outer wall 31 to the third support column 3/6 or 3/8 main body to elasticity elastic restoring force acting against the deformation by member 3d acids, or that propagates in the order of the coil spring 3d / 4 external force (rotation of a user sitting on the seat 5), increases the projections 3 v · 3 with v · 3 Continues working until v reaches the deformation limit.
In a state of, Stability the user provided in the projection 3 v · 3 v · 3 v at the time of the抜力with (elastic restoring force due to the characteristics), the elastic member 3d acids or coil spring that Osame置the spring insertion hole 3a 3d / 4 and Stability provided in the third strut 3/6 or 3/8 body (material or elastic restoring force due to the characteristics of a shape,) is biasing force of reversing the seat 5 at the same time is released (action-stress) Switch to

Also, a seat 5 which is vertically strut container 3c / 1 directly below the seat opening 5a, the projections 3 v which laterally set by integral molding in a state in which a certain space therebetween in the outer wall 31 of the moderately below the upper - a 3 v-3 v, in embodiments using the projections 3 v third column 3 such constituted by a seat joint 3b which is provided around the outer wall 31 of the lower friction surface 40 and the seat joint during twisting motion It is desirable to take measures to reduce resistance due to friction with the upper surface of the portion 3b.
According In the configuration, such as sliding means 35 comprising a ball 42 which is press-fitted to the spacing of the outer ring 36 and inner ring 37 shown in Figure 24 to either the top or friction surface 40 of the seat junction 3b (ball bearings) It is preferable to attach a member for smooth rotation.

In the structure you attached a sliding means 35 shown in the illustrated example of FIG. 24, until the protrusion swaying during twisting motion 3m · 3m · 3m right or left inner wall surface projections 3 v · 3 v · 3 v abuts the the third post 3/6 or from the seat 5 is lightly idle in a state in which the upper friction resistance is greatly reduced 3/8, the third column 3/6 or 3/8 body and elastic member 3d acids Alternatively, the elastic restoring force provided as a characteristic (stability) in the coil spring 3d / 4 is not transmitted to the user as a drag force that reverses the seat 5.
However, since the horizontal set integrally molded with the outer wall 31 of the projection 3 v · 3 v · 3 v in the illustrated example shown in Figure 24, each of the projections 3 v are either projection swaying 3m · 3m · 3m left inner external force due to the rotation of the user sitting on the seat surface 5c from the time of starting to deform in contact with the wall surface, the outer wall of the projection swaying 3m · 3m · 3m through the projection 3 v · 3 v · 3 v of 31, i.e. propagated in the order of the third column 3/6 or 3/8 elastic member 3d acids or coil spring 3d / 4 was Osame置the body and the spring inserting hole 3a.

Therefore, a rubber-based material that mainly plays a role of urging the reverse rotation of the seat 5 during twisting movement is used, and the elastic restoring force (stability) that the protrusions 3 v that are horizontally integrated at three locations on the outer wall 31 have characteristics. And a rubber-based material that plays a role of changing or adjusting the elastic restoring force that works against the deformation in which the third column 3/6 or 3/8 bends (tilts / tilts) in the circumferential direction during the turning motion. It made elastic member 3d acids, or elastic restoring force to the coil spring 3d / 4 made of metallic material having a characteristics (Stability), as a third column 3/6 or 3/8 body characteristics It becomes possible to classify the elastic restoring force (restorability) possessed more clearly.

According Specific examples of the structure, the inner surface 41 of dimensions among which fits on the outside of the made-length> length of the outer ring 36 of the sliding means 35 Rutotomoni outer surface 41a, toward a plurality of stoppers 38 inward at the upper end a cylindrical portion 43 which is horizontal set, and Katachi設the outer housing 39 made circumferentially provided with washer-like friction surface 40. the lower end of the cylindrical portion 43 to the lower end of the post fitting hole 3c / 6, the projections 3 v respectively arranged schematic perspective view of a strut container 3c / 2 consisting of a plurality of sets of protrusions swaying 3m forming the left and right pair of laterally set is 24 upwardly from the inner wall surface 3c / 5 inwards corresponding to the arrangement Is shown in
The inner diameter of fitting an annular protrusion 44 projecting from the upper surface of the inner edge (see FIG. 25), the outer wall 31 in a state where the lower end of Ru is placed in the inner ring 37 to the upper end of the protrusion 44 third consisting of a seat joint 3b / 1 consisting of sliding means 35 having an inner ring 37, the sliding means 35 above the outer wall 31 and the projections 3 v · 3 v · 3 v which laterally set outward A schematic perspective view of the columns 3/6 and 3/8 is shown in the lower part of FIG. 24 or the lower part of FIG.
Alternatively , an annular protrusion 44 (see FIG. 25) protruding from the upper surface of the inner edge and an inner diameter that fits the outer wall 31 with the lower end of the inner ring 37 placed on the upper end of the protrusion 44. The seat joint portion 3b / 1 includes a sliding means 35 having an inner ring 37, and projections 3v, 3v, and 3v that extend laterally outward from the outer wall 31 above the sliding means 35, and the accommodating portion 3e is the inner wall 32. A schematic perspective view of the fourth support 3n / 6 provided on the side is shown in the lower part of FIG. 24 or the lower part of FIG.
In the illustrated example, the projecting portion 44 and the seat joint portion 3c / 1 are integrally molded using a rubber-based material, regardless of the material, but the lower end of the inner ring 37 and the upper end of the projecting portion 44 are not particularly limited. The height (height) at which a constant interval (gap) is generated between the lower end of the outer ring 36 and the upper end of the seat joint portion 3b / 1 in the state where the outer ring 36 abuts.

Also, when the outer housing 39 (seat 5) is fitted from above the columns in response to the structure of the third columns 3/6, 3/8 or the fourth column 3n / 6 shown in the lower example of FIG. in, which has an inner surface 41 of dimensions among the outer surface 41a and fitting the outer ring 36, a cylindrical portion 43 within which is horizontally provided on the upper toward a plurality of stopper 38 abuts inwardly on the upper end of the outer ring 36 , strut container 3c / 2 main portion which is shaped set integrally molded outer housing 39 consisting of the washer-shaped friction surface 40. circumferentially provided at the lower end of the inner cylindrical portion 43 to the lower end of the post fitting hole 3c / 6 A schematic perspective view is shown in the upper part of FIG.
Further, as shown in FIG. 24, an outer housing 39 showing a state when the outer housing 39 (seat 5) is mounted from above the protrusions 3 v , 3 v , 3 v and the inner surface 41 is fitted to the outer surface 41a. A schematic perspective view of the sliding means 35 is depicted by a three-dot short chain line and a broken line.

In the illustrated example of FIG. 24, are made to the outside diameter of the inner diameter of ≧ outer ring 36 of the inner surface 41 (outer surface 41a · sliding means 35), the projections 3 v · 3 v · 3 v and seat junction 3b / 1 Tokyo the third post 3 such upward from the outer housing 39 (strut container 3c / 2) when fitted with a seat 5 and fitted on made, was fitted to the outer surface 41a (outer ring 36) to the inside of the inner surface 41 In order to avoid contact between the upper surface of the seat joint portion 3b / 1 and the rear surface of the friction surface 40, the length of the outer ring 36 is greater than the height of the cylindrical portion 43 (the height of the outer housing 39) including the friction surface 40. It has been.
Further, when the inner surface of the inner ring 37 (sliding means 35) is fitted to the outer wall 31, the upper end of the projecting portion 44 that has an annular shape protruding from the inner edge of the upper surface of the seat joint portion 3b / 1 , Since the lower end of the ring 37 is in contact with the lower surface of the ring 37, a space having a height equivalent to that of the protrusion 44 (see FIG. 29) is formed on the back surface of the friction surface 40 and the upper surface of the seat joint portion 3b / 1. Arise.
Accordingly, the back surface (outer housing 39) of the friction surface 40 that follows the twist motion of the user seated on the seat surface 5c does not come into contact with the upper surface of the seat joint 3b / 1. and the inner wall surface of the projection swaying 3m · 3m · 3m, projections 3 v · 3 v · 3 v is also smoothly rotated with respect to left or right direction within a range of up to abut.

In such structure, the seat 5-5/1 the third column 3 acids, or a fourth strut 3n such, since it has detachably configured via sliding means 35, or the third column 3 such body, during twisting motion fourth protrusion role in propagating the elastic restoring force to the seat 5, 5/1 post 3 such body and the elastic member 3d acids or coil spring 3d / 4 has had horizontal set integrally molded to the outer wall 31 3 v - 3 v・ 3 v bears.
On the other hand, the third column 3 such during turning movement, or the fourth stress acting against deformation directed in the circumferential direction of the struts 3n compound (drag) is Osame置the spring insertion hole 3a or accommodating portion 3e elastic The elastic restoring force (restorability) inherent to the members 3d or the coil spring 3d / 4 and the third support column 3 or the fourth support column 3n is assumed.
From this point, just below the first support 3 acids, or the second upper end of the strut 3n such or seat junction 3b top and seat 5-5/1 of the back (the seat opening 5a, with bonding means such as by adhesive ) and compared to be that the structure fixed to, when a user sitting on the seat surface 5c · 5c / 1 switches to twisting motion from the pivoting movement, the elastic member 3d acids or coil springs from spring insertion hole 3a or accommodating portion 3e The trouble of taking out 3d / 4 and reducing the elastic restoring force of the third column 3 or the fourth column 3n can be omitted.

Subsequently, a seat 5, 5/1 having a post container 3c / 2 directly below the seat opening 5a - 5a / 1, the protruding portion 44 (see FIG. 29) protruding from the edge of the upper surface inner a seat junction 3b / 1, in a state that will be placed on the projecting portion 44, the sliding means 35 fitted to the inner surface of the inner ring 37 to the outer wall 31, and laterally disposed on the outer wall 31 of the upper of the sliding means 35 If conducted various stretching and muscle training using embodiments constructed using the third strut 3/6 - 3/8 consisting of the projection 3 v, 3 v, 3 v, functions provided in these The following will describe the operational effects that the system brings to the user.
For example, it is assumed that the user sitting on the seat of such configuration 5-5/1 (see FIG. 24) to perform a twisting motion to the turning motion, or alternating left and right draw circumference.
In this case, the post container 3c / 1 and the seat 5 which is vertically immediately below the seat opening 5a, and the projections 3 v · 3 v · 3 v was horizontally provided on the outer wall 31, beneath these projections 3 v compared to the illustrated example of FIG. 16 that is configured using the third strut / 6 the seat junction 3b has circumferentially, in the configuration shown in the illustrated example of FIG. 24, the seat 5-5/1 during twisting motion forward, reverse it becomes smoother, until each of the projections 3 v on the inner wall surface of the projection swaying 3m · 3m · 3m abuts, and an elastic restoring force with the third strut such body according elastic member 3d acids, or from an elastic restoring force with the coil spring 3d / 4 is not applied, the elastic source return force rubber-based material which acts upon deformation of the protrusions 3 v · 3 v · 3 v has a characteristic (Stability) is This is reflected more clearly in the muscle groups around the user's stomach and waist.

Further, as a structure for changing or adjusting the elastic restoring force provided on the projections 3 v , 3 v , 3 v acting against the rotation direction of the user seated on the seat 5/5/1 during the twisting motion, the sliding means is provided from the upper end. The guides 45, 45, 45 having a T-shaped cross section are recessed in three locations on the outer wall 31 that extend over 35 in a position corresponding to the positions of the protrusion swing grooves 3m, 3m, 3m. of freely fastening to the T-shaped locking 3 species wall thickness made different by using the material of rubber-rich Katachi設be Rutotomoni resilient bottom projections 46 projections 3 v / 1 to 3 v / 3, shown in the third strut 3/6 or fourth column 3 / 5.3 / 7 Figure 30 and Figure 31 an enlarged perspective view of essential parts, it includes a seat junction 3b / 1 and sliding means 35 Has been.
In such structure, by replace by selecting one of the projections 3 v / 1~3 v / 3 of the thickness desired by removing the seat 5-5/1 These struts (width), the projections 3 v / The elastic restoring force (stability) provided as a characteristic of the rubber-based material that works in the direction opposite to the direction of deformation from the time when 1 to 3 v / 3 contacts the inner wall surface of each of the protrusion rocking grooves 3m, 3m, and 3m. It becomes possible to vary or adjust the degree of action.

For example, since the guide 45 is recessed in three places of the outer wall 31 of the elastic body 30 in the illustrated example of FIG. 30 and 31 constituting the third strut 3/6 or fourth post 3n / 5 or 3n / 7, , To engage all the guides 45 with the thick protrusions 3 v / 1, or to engage all the guides 45 with the medium protrusions 3 v / 2 , or to connect the thin protrusions 3 v / 3, or 3 v / 1. Since various combinations such as 3 v / 2 · 3 v / 3 are possible, the elastic restoring force that reverses the seat 5 · 5/1 in the opposite direction to the user's movement during twisting exercise There are many options for the amount of action.
Further, when the projections 3 v / 1 · 3 v / 2 · 3 v / 3 having different elastic restoring forces (drags) are used in combination, the drag force that rotates the seat 5 · 5/1 in the reverse direction is a projection. The different elastic restoring forces of 3 v / 1 · 3 v / 2 · 3 v / 3 are combined and transmitted to the user who sits on the seat 5 · 5/1 and performs the twisting motion.
Incidentally in the illustrated example of FIG. 31, the thickness of the projections 3 v that Katachi設the locking projections 46 on the bottom are shown the three 3 v / 1 to 3 v / 3 is.
However, by further diversifying the thickness of these protrusions 3 v / 1 to 3 v / 3, or by increasing the number of guides 45 and horizontally arranging the same number of protrusion rocking grooves 3m on the inner wall surface 3c / 5, choice of the action of characteristics for each thickness acting in opposite directions the elastic restoring force (elasticity) are featured in a different projection 3 v species (stress-drag) becomes much more abundant than the direction of movement of the user's time.

User third column 3/6 seated on the seat 5, 5/1 of the embodiment constructed by using the illustrated examples presented in FIGS. 30 and 31, or the fourth post 3n / 5-strut 3n / 7 when performing a twisting motion as the axis, the guide 45, 45 respectively to be engaged with the-45 projections 3 v / 1 · 3 v / 2 · 3 v / 3 is projecting pivot grooves 3m, 3m, 3m within each against the action of the elastic restoring force (stress-drag-righting) that occurs when returning from a time point to start contact with deformation on the wall to its original shape, when the further progress of rotation of the seat 5-5/1, its Rotate the seat 5/5/1 in the same direction with the strength of the stomach and waist.
In such a state, as the rotation of the seat 5 · 5/1 proceeds, the stress (elastic restoring force / stabilizing action) generated when the plurality of protrusions 3v are deformed increases.
Subsequently, the projections 3 v with increasing species variations, the guide 45, 45, 45 (outer wall 31) through a third column 3/6, or fourth post 3n / 5-strut 3n / 7 body and external force from the rotation of the spring insertion hole 3a or the elastic members 3d acids were Osame置the housing portion 3e or user sitting on the seat 5, 5/1 the coil spring 3d / 4, is that propagates.
These events, the elastic restoring force generated against the third column 3/6, or fourth post 3n / 5 · post 3n / 7 deformation direction included as a characteristic in the body (in this case the left-right twist direction) (Stability ) And an elastic restoring force (stability) generated against the deformation direction (in this case, the left-right twist direction) provided as a characteristic of the elastic member 3d or the coil spring 3d / 4.

By the way, compared to the amount of elastic restoring force generated when the thin projection 3 v / 3 made of a rubber material is deformed, the elasticity generated when the thick projection 3 v / 1 made of the same material is deformed. The amount of restoring force is naturally strong. (See Figure 31)
Specifically, when a twist exercise is practiced in a state where the thick protrusions 3 v / 1 are engaged with all the guides 45, the elastic restoring force generated when each of the protrusions 3 v / 1 is deformed is strong point, from the point integrated projection 3 v / 1 and the third column 3/6 or fourth post 3n / 5 · post 3n / 7, is in a state of being engaged with the guide 45, in the state of the As the deformation of each projection 3 v / 1 increases, the external force (rotational force) due to the user's operation is the third support column 3/6 , or the fourth support column 3n / 5, the support column 3n / 7 main body, and the elastic members 3d. or that propagates to the coil spring 3d / 4.
Thus, the respective projections 3 v / 1, the third column 3/6 body or elastic restoring force generated at the time of deformation of the fourth strut 3n / 5 · post 3n / 7 body and the elastic member 3d acids or coil spring 3d / 4, Since the load on the rectus abdominis, external obliques, latissimus dorsi and the gluteus medius is accumulated in a short period of time when the user rotates the seat 5/5/1, the strengthening of these muscle groups becomes even more efficient. you.
There is also means for applying the structure of the illustrated example introduced in FIGS. 30 and 31 to the first support column 3 or the second support column 3n.

On the other hand, when a twisting exercise is performed using a rotary chair used in office work or a table, there is no drag (restoring force) that reverses the user's rotation.
In this case, in order to strengthen and strengthen the user's rectus abdominis muscle, external abdominal oblique muscles, latissimus dorsi muscle, and the gluteus medius, it is necessary to devote a great deal of time to the twist exercise.
However, in the embodiment shown in the illustrated examples presented in FIGS. 24 and 29, the seat 5-5/1 is configured detachably with the top of the third strut 3/6, 3/8 or fourth post 3n / 6, ing.
In addition, to avoid the lower end of the post fitting hole 3c / 6 during twisting motion by attached the seat junction 3b / 1 containing sliding means 35 (friction surface 40), the friction between the upper end of the seat junction 3b (contact) since the, is integrally molded with the outer wall 31 to the horizontal setting the projections 3 v · 3 v · 3 v abuts the inner wall surface of the projection swaying 3m respectively, the projections 3 v and third strut 3/6 · 3/8, or elastic restoring force to the fourth strut 3n / 6 and the elastic member 3d acids or coil spring 3d / 4 was Osame置the spring insertion hole 3a or accommodating portion 3e has no effect.
However, as modified with the projections 3 v abuts the inner wall surface of the projection swaying groove 3m, respectively increases, the external force (the rotational force of the user sitting on the seat 5, 5/1) has for each of the projections 3 v third strut 3/6 - 3/8 via the outer wall 31 or from Rukoto be propagated to the inside of the fourth post 3n / 6,, in accordance with the amount of rotation of the user sitting on the seat 5, 5/1 increases projections 3 v, 3 v, 3 v elastic restoring force - exerted that third struts 3/6, 3/8 or the fourth elastic member 3d acids or coils that join the elastic restoring force - further comprising struts 3n / 6 is, with the The urging force that reverses (reverses) the seat 5 · 5/1 is increased step by step in the order of the spring 3d / 4.
In such structure, the elastic restoring force against the deformation of these struts during twisting movement and (stress-drag), resulting in the projections swaying 3m respective inner wall surfaces on the projection 3 v · 3 v · 3 v deformed in contact with The sharing of the elastic restoring force (stress / drag) becomes clearer than the example shown in FIG.

Further, in the illustrated examples presented in Figure 31 at regular intervals guide 45 at three positions on the outer wall 31 of the elastic body 30 constituting the third strut 3/6 or fourth post 3n / 5 · 3n / 7, and recessed, prepared three different projections 3 v / 1 · 3 v / 2 · 3 v / 3 of the thickness was Katachi設the locking projections 46 on the bottom to engaged with the guide 45 (width) Since the outer wall 31 (the guide 45) is configured to be freely detachable, before the twisting motion is started, the protrusion 3 having a different thickness (width) is replaced with the v type so that the seat 5/5/1 rotates in the rotational direction. It is possible to adjust the stress (elastic restoring force / restorability) acting against (reversely) to change to the elasticity (biasing force / drag) close to the user's request.
For example, when a user who desires strong muscle training performs a twist exercise using the embodiment configured by using the illustrated example introduced in FIG. 31, the thick protrusion 3 v / 1 is placed on all the guides 45. by engaged with, from Rukoto be integrated each projection 3 v / 1 and the outer wall 31 (third support column 3/6, 4th post 3n / 5 · 3n / 7) , the projections 3 v / 1 ( in this case, in addition to a strong elastic restoring force included as a characteristic in three), the elastic restoring the elastic member 3d acids or coil spring 3d / 4 and the third strut 3/6 or fourth post 3n / 5 · 3n / 7, having Power is added.
In such a state, against the elastic restoring force provided to each protrusion 3 v / 1 and the elastic members 3d , or the coil spring 3d / 4 and the third support post 3/6 , or the fourth support post 3n / 5 / 3n / 7. The user advances the rotation of the seat 5/5/1.
Therefore, compared to conventional rotary chairs where no load can be generated during twist exercise, the user's rectus abdominis, external obliques, gluteus medius and latissimus dorsi muscles are subjected to a greater load. Contributes to shortening the time required to train the group.

When performing the pivoting movement of the user sitting on the seat surface 5c · 5c / 1 draws a circle, such as shape of the ellipse or 8, third strut 3/6 Made of rubber-based material or, fourth elastic restoring force to the strut 3n / 5 · 3n / 7 body originally has characteristics thus tilting direction (inclination direction) to repel the opposite direction (the elastic return) or stress acting upon deformation (elastic restoring force - Stability in addition to), the elastic restoring force acting as a stress during deformation with a spring insertion hole 3a elastic member 3d acids or coil spring 3d / 4 was Osame置or in housing portion 3e, (Stability) is added.
Therefore, the third consisting of a seat junction 3b / 1 containing sliding means 35 introduced in FIG. 31, the guide 45 and disengageably constructed the projections 3 v / 1 · 3 v / 2 · 3 v / 3 Metropolitan post 3/6 or the fourth post 3n / 5 · 3n / 7, the chair 1 the strut container 3c / 2 can exercise a configuration using a seat 5-5/1 comprising directly below the seat opening 5a, embodiment habitually twisting motion and oval using, or when practiced together swirling motion to draw such a figure eight, the user of the belly wrought the rectus muscle and the external abdominal oblique muscle and gluteus medius, Not only strengthening, but also strengthening the latissimus back.

In this case, the projection 3 v / 1 · 3 v / 2 · 3 v / 3 having different thicknesses is selected as a different combination or a single combination according to the user's request, and the guide 45 is selected. in Rukoto is engaged wear, and varying greatly drag (elastic restoring force, stress) acting on the seat 5, 5/1 in twisting motion, since it is possible to finely adjust, seats 5 & Diversified options for drag (elastic restoring force) acting on users seated on 5/1.
Specifically, during turning movement in response to the user's desire for various physique or strength, than increasing or decreasing the pay registered number of the elastic members 3d acids or coil spring 3d / 4, the third strut 3/6, Alternatively, the elastic restoring force acting against the deformation (tilting / tilting / curving) in the circumferential direction of the fourth column 3n / 5 / 5n / 7 can be adjusted to an appropriately close state.
In addition, during the twist movement, the seats 5 5/1 are inverted by engaging the protrusions 3 v / 1 · 3 v / 2 · 3 v / 3 in various ways and engaging with the guides 45 · 45 · 45. It is also possible to adjust the biasing force (elastic restoring force) to an appropriately close state.
Thus, a variety of physique or muscle training or belly according to the user's physical strength, around the waist of the diet is appropriate, and efficiently from being promoted, at the same time aesthetic in excellent form making as well as a healthy, To contribute.

Therefore, the elastic restoring force against the rotation of the user sitting on the seat 5 or 5/1 when twisting motion urged or when de-energized, the embodiment shown in the illustrated example of FIGS. 24 or FIG. 29 31 Thus , the trouble of removing the seat 5 or 5/1 from the upper part of the third support column 3 or the fourth support column 3n (elastic body 30) can be saved.
Incidentally, when the twist movement or the turning movement is performed using the embodiment shown in the example of FIG. 28 or the embodiment shown in the examples of FIGS.

In the following, a post container 3c / 2 (see FIG. 24, 29), a seat junction 3b / 1 projecting from the projecting portion 44 of the annular rim portion of the upper surface inside of the inner ring 37 to the protrusion 44 in a state where the lower end of Ru is placed, a sliding means 35 which is fitted on the outer wall 31, a guide 45, 45, 45 which is recessed at a position spaced a predetermined distance to the outer wall 31 of the sliding means 35 upwardly from the upper end the third pillar consists 3 v / 3 Metropolitan of 3 v / 2 · thin thereof a locking projection 46 which engaged with the guide 45 of the wall thickness was Katachi設the bottom projection 3 v / 1 · medium build 3 / 6, or to introduce a fourth strut 3n / 5 · 3n / 7 using (see FIG. 30, 31) embodiment which applies the configuration below.

For example, forward reversible or power source such as an existing motor repeating the forward reverse within a certain range the third strut 3/6, or 4th post 3n / 5 · 3n / 7 of the starting point 3w (Figure 1 Reference) Assume a structure that is attached to the lower leg 2 and transmits the eccentric rotation to these columns by the rotational force of the power source. (Not shown)
In such a structure, a cylindrical body to be attached to the tip of the rotating shaft of the power source is provided, and a concave fitting portion that is fitted in a state where the cylindrical body is closely fitted is recessed on the bottom surface near the outer wall 31 of these columns, The cylinder attached to the tip of the rotating shaft according to the fitting portion is fitted. (Not shown)
In this case, the third strut 3/6, or 4th post 3n / 5 · 3n / 7 cylinder attached to the tip of the rotary shaft in the fitting portion which is recessed into the bottom surface of the distant outer wall 31 toward the center of the Since the body is fitted, when such a power source is activated, these columns start rotating eccentrically.
Incidentally, in the first embodiment described above, the threaded tube 2d which is screwed to the inside of the leg portion 2 (not shown), such first strut 3 and the third column 3 acids, or the second strut 3n acids or a screw 3f being engraved on to moderate an upper location from the lower end of the fourth strut 3n acids are joined by screwing, is fixed to the leg 2.

Specifically, when the recessed fitting portion according to the position proximate the center of the third strut 3/6 or fourth post 3n / 5 · 3n / 7, , eccentric rotation of the starting 3w (see FIG. 1) even slight deflection width, the third strut 3/6 or fourth post 3n / 5 · 3n / 7 is made of a resilient material, the starting point 3w point of action 3u (see Fig. 2) since the bets are positioned in the vertical direction of the remote locations, to bring the eccentric rotation than eccentric rotation of the fitting portion which is recessed in the outer wall 31 near the bottom of these struts draw large oblong seat 5 Can be realized.
In this case, reduces the pay registered number of the elastic members 3d acids or coil spring 3d / 4, the elastic return force that acts against the deformation direction of the third strut 3/6 or fourth post 3n / 5 · 3n / 7, In a state in which is reduced, since the flexibility of these columns in the circumferential direction is improved (elastic restoring force is reduced), the eccentric rotation of the seat 5 is further elongated.

Further, as a structure that mechanically causes eccentric rotation in the seat 5, one end movably connected to a piston of a hydraulic cylinder or a pneumatic cylinder, a rod having the other end of the same structure at a position facing the one end, and the rod A large-diameter gear that protrudes on a surface away from the rotation axis, a small-diameter gear that engages with the module of the large-diameter gear, and a module of the small-diameter gear. and fixedly further small-diameter pinion gear to the third strut 3/6 or bottom surface of the outer wall 31 side of the fourth strut 3n / 5 · 3n / 7, the module, the center of the pinion gear at the top of the leg 2 There is also a measure to support the shaft rotatably. (Not shown)
In such structure, when you start the hydraulic cylinder or pressure cylinder, reciprocating motion of the rod is switched to the rotation at the same time the large-diameter gear when transmitted to the projection which is projected onto the surface of the position away from the rotation axis, the small diameter gear from fixed to the bottom surface of the outer wall 31 closer, the transmission while increasing the rotational force to the rotatable shaft supported pinion gear centered on the legs 2, it switched to strong eccentric rotation of these posts.

Subsequently, the upper edge portion of the first post 3 such that no projecting upper seat junction 3b or 3b / 1 introduced in FIG. 1, a seat opening an adhesive surface 6z that depicted in Figure 5 above the shaded An elastic member 3d / 1 to 3d / 3 (see FIG. 11) or a coil spring 3d / 4 (not shown) having a structure that is bonded (connected) immediately below 5a and is slightly shorter than the length of the spring insertion hole 3a. A specific example relating to the embodiment in which the spring is inserted into and removed from the opening 3a / 1 opened at the upper end of the spring insertion hole 3a will be described below with reference to the drawings.

18 is a schematic side perspective view of the first column 3/3 in a state where the upper portion is inserted into the column insertion hole 3c / 6 at the lower end of the column container 3c , and the first column 3/3 is shown. The elastic members 3d / 1 to 3d / 3 are made to have a total length slightly shorter than the total length of the plurality of spring insertion holes 3a provided inside , and are fixedly provided with attachment means 3i that adheres to the other end at one end. It is shown.
In the illustrated example, elastic members 3d / 1 to 3d / 3 made of a rubber-based material are provided separately , which are set to be slightly shorter than the entire length of the spring insertion hole 3a, and these elastic members 3d / 1. The state before the sticking means 3i fixed at one end of ˜3d / 3 and the stick-like extraction member 3d / 5 fixed at one end with the attaching means 3i having the property of attaching is shown.

For example, in the embodiment shown in the illustrated example of FIG. 18, when the attachment means 3i you fixed to one end of the elastic member 3d / 1~3d / 3 is a magnet, one end of the sampling member 3d / 5 as the object to be attached body attachment means 3i you fixed to the magnet different polarities or may be iron.
On the other hand, if the attachment means 3i you fixed to one end of the elastic member 3d / 1~3d / 3 is iron, the attachment member you fixed to one end of the extraction member 3d / 5 may be a magnet.
Incidentally, according elastic member 3d / 1~3d / 3 of the total length, or when using a magnet to one end of the extraction member 3d / 5 as attachment means 3i and fixed, a single one of the elastic members 3d class to retrieve What is necessary is just to have sufficient magnetic force.
In such structure, the elastic member 3d / 1~3d / 3 fixedly provided with attachment means 3i on at least one end, but suffice with a single and extraction member 3d / 5 to adhere to at least one end unit 3i is fixed, preferably secured to Rukoto attachment means 3i in extraction member 3d / 5 and the elastic member 3d / 1~3d / 3 both ends, in this case, the attachment means 3i is extraction member 3d / 5 or elastic member 3d, / 1 It is possible to save the trouble of confirming each end of ˜3d / 3, thereby improving convenience.

Specifically, the overall length of the extraction member 3d / 5 is set to approximately 100 mm, and the attaching means 3i is fixed at least at one end.
Then, the elastic members 3d / 1 to 3d / 3 have a total length that is about 80 mm shorter than the length from the opening 3a / 1 to the end point 3k (the total length of the spring insertion hole 3a), and the adhering means 3i is fixed to at least one end thereof. Set up.
In such a structure, with the other end of the elastic members 3d / 1 to 3d / 3 in contact with the end point 3k, one end on the side where the adhering means 3i is fixed to the elastic members 3d / 1 to 3d / 3, The elastic member 3d / 1 so that the other end of the extraction member 3d / 5 protrudes approximately 20 mm from the opening 3a / 1 when the member 3d / 5 is combined with one end on the side where the adhering means 3i is fixed. It is sufficient that the length of any one of ˜3d / 3 or the extraction member 3d / 5 is adjusted.
Incidentally, when the structure according to the embodiment introduced in the illustrated example of FIG. 1 is applied, it is not necessary to consider the thickness of the seat surface 5c, and therefore the seat 5 (seat surface 5c · 5c / 1) is made thin and light. It becomes possible.

Also, if the attachment means 3i you fixed to an end portion of the elastic member 3d / 1~3d / 3 in the embodiment shown in the illustrated example of FIG. 18 is a Velcro (registered trademark), extraction member 3d as the object to be attached body / the end of the 5 you fixed attachment means 3i may be any material properties to coalesce attached with Velcro (registered trademark).
Incidentally, when a Velcro tape (registered trademark) is fixed to the end of the extraction member 3d / 5 and used as the attachment means 3i, the adhesive force is sufficient to take out one of the elastic members 3d / 1 to 3d / 3. If you have.
When used as an elastic member 3d such equivalent of the total length of the total length of the iron coil springs 3d / 4 may if magnets are fixed to the end of the extraction member 3d / 5 side.

In addition, the extraction member 3d / 5 introduced in the illustrated example in the upper part of FIG. 18 and the elastic members 3d / 1 to 3d / 3 having an overall length shorter than the attaching means 3i and the spring insertion hole 3a or the iron coil spring 3d / 4 are used. the embodiments using, not other embodiments or problems be employed in the modification relates thereof.
Incidentally, this structure is a simple structure in which the bonding surface 6z (see FIG. 5) provided around the opening 3a / 1 located at the upper end of the first support column 3 introduced in FIG. 1 is bonded directly below the seat opening 5a. Suitable for.

For example, a attachment means 3i is magnet fixed to the end portion of the elastic member 3d / 1~3d / 3 or Velcro (registered trademark), fixedly attachment means 3i nature to adhere to these in the end In the state where the extracted member 3d / 5 and the elastic members 3d / 1 to 3d / 3, which are made shorter than the entire length of the spring insertion hole 3a, are attached and joined together , the seat 5 (seat surface It is assumed that the user seated in 5c) performs a twist exercise that repeats alternate left and right torsion with the waist and hips as axes.

In this case, since the magnet is used as the attachment means 3i or Velcro (TM), is an adhesion sufficient to take out a single one of the elastic members 3d / 1~3d / 3, in particular, the first post 3 in you bonding structure directly below the seat opening 5a of the adhesion surface 6z of the kind upper, when a user sitting on the seat surface 5c starts to twist movement, both of the first post 3 such a spring insertion hole 3a Immediately driven and twisted in the direction of user rotation.
In the initial stage of such a state, the elastic members 3d / 1 to 3d / in which they are placed are increased as the twists (deformations) of the first column 3 main body and the spring insertion holes 3a provided in these columns increase. The attachment means 3i fixed to the lower end of the extraction member 3d / 5 is separated from the attachment means 3i fixed to the upper end of the spring 3 in the deformation direction of the spring insertion hole 3a. At the same time , the extraction member 3d / 5 is first driven by the user's rotation direction.
According state is driven in the first post 3 such body as well as the rotational direction of the elastic member 3d / 1~3d / 3 deformation while user who is Osame置the spring insertion hole 3a as it progresses.

Furthermore, a large number of elastic members 3d / 1 to 3d / 3 placed in many spring insertion holes 3a and the same number of extraction members 3d / 5 are attached to each other and seated on the seat 5 in a state where both are combined. It is assumed that the user performs a twisting motion that repeats alternate left and right torsion with the waist and buttocks as axes.
In this case, since it magnet used as attachment means 3i is a magnetic force sufficient to take out any one of the elastic members 3d / 1~3d / 3, also Velcro (TM) is a well known adhesive force It is obvious that the coupling force of the large number of elastic members 3d / 1 to 3d / 3 and the same number of extraction members 3d / 5 is overwhelmingly small compared to the physical strength of adults.
Thus, both are united together to deposit the number of elastic members 3d such as many extraction member 3d / 5, even in a state of being Osame置to many spring insertion hole 3a, first comprises a spring insertion hole 3a The extraction member 3d / 5 separated from the upper end of the elastic members 3d / 1 to 3d / 3 and separated as the torsion (deformation) of the one support column 3 increases is separated from the rotation direction of the user (the spring insertion hole 3a). Follow (transformation).
In a state of drag (elastic restoring force) with the elastic member 3d / 1~3d / 3 located below the extraction member 3d / 5 it is slightly propagated only on the first post 3 class.
Accordingly, in the initial stage of the twist movement, the elastic restoring force acting in the direction opposite to the deformation direction (in this case, the twisting direction) of the first support column 3 is the state in which the elastic members 3d / 1 to 3d / 3 are not placed. Follow.

For example, when a heavy user sits on the seat 5 (seat surface 5c) and performs a twisting motion, the elastic member 3d / 1 to 3d / 3 combined with the extraction member 3d / 5 via the attachment means 3i, or In the state where iron coil springs 3d / 4 having the same total length as these are previously placed in a large number of spring insertion holes 3a, they are elastic to the elastic restoring force (drag / stress) provided as a characteristic of the first column 3 main body. joined by members 3d / 1~3d / 3 or elastic restoring force included as a characteristic in the coil spring 3d / 4, (drag-stress), the rigidity against the deformation is enhanced overall.
In such a state, the first support column 3 in the stationary state improves the strength against the flatness caused by the downward weight (load) of the user seated on the seat 5 and draws an ellipse or a figure of 8 or the like. during turning movement, it also enhanced elastic return force that acts against the deformation direction of the first post 3 class.

However, when the user seated on the seat 5 (seat surface 5c) performs a twisting motion, the extraction member 3d / 5 is deformed (moved) so that the upper part of the spring insertion hole 3a is driven and twisted almost simultaneously with the start. At the time of follow-up, the attachment means 3i fixed to the lower end of the extraction member 3d / 5 and the attachment means 3i fixed to the upper end of the elastic member 3d / 1 to 3d / 3 or the coil spring 3d / 4 are respectively provided. Separate and separate.
In a state of, regardless of the number of the elastic members 3d / 1~3d / 3 or coil spring 3d / 4 which is Osame置the spring insertion hole 3a, adhesion effect of the elastic return force that acts against these variations It is reduced that it extends into the spring insertion hole 3a located above the lower end of the means 3i.
Therefore, the elastic member 3d acids made the length of the total length> of the spring insertion hole 3a, or a coil spring 3d / 4 compared to the same number Osame置state, in this structure, the upper portion of the first support 3 such elastic restoring force acting against the deformations screws laterally to the energy dissipation.
Thus, the configuration using the elastic member 3d acids made the length of the total length of the spring insertion hole 3a>, or a coil spring 3d / 4, the attachment means 3i and extraction member 3d / 5 is bonded directly below the seat opening 5a This is a suitable means for performing a twisting motion in a structure (see FIGS. 1 to 4) in which the surface 6z (the upper end of the first support column 3) or the upper end of the seat joint 3b is directly joined.

In response to this structure, at least a deposition unit 3i fixedly provided on one end, the elastic member 3d /. 1 to the attachment means 3i nature adhering to the attachment means 3i fixedly provided at at least one end of the sampling member 3d / 5 and 3d / 3, detachably constructed from post fitting hole 3c / 6 located at the lower end of the column container 3c / 1 was shaped set at fixed or integrated directly below the seat opening 5a (see FIG. 24) third Katachi設be Rutotomoni different meat locking projections 46 engaged with the guide 45, 45, 45 which is recessed in the outer wall 31 of the strut 3/6 or fourth post 3/5 or 3/7 in the bottom was and the projections 3 v / 1~3 v / 3 made in the thickness, the embodiment shown in the illustrated example of FIG. 31 having a seat junction 3b / 1 containing sliding means 35, a number of the locking portion 6b vertical the longitudinal crosspieces 6 fixedly provided in the direction of the multi-stage, provisions made in the large fractional species different spaces Frame 6a / 1 Rukoto be configured in the embodiment shown in the illustrated example of FIG. 20 comprising a plurality of types of regulating means 6a is desirable to have.

In such a configuration, the outer frame 6d of the restricting means 6a having the restricting frame 6a / 1 (see the lower part of FIG. 20) in the narrow space adjacent to the periphery of the outer wall 31 after the removal of the seat 5 · 5/1 is used as the vertical beam 6 By engaging with the locking portion 6b fixed to the uppermost stage, the safety of the user seated on the seat 5/5/1 when stationary is improved. For this reason, it is possible to modified with simple steps to everyday use of the chair, such as office, or for the table.
At the same time, large when switching circumference pivoting movement to draw the outer frame 6d of the restricting means 6a having a seat 5-5/1 wide space after removal of the regulating frame 6a / 1 (see FIG. 20 above), the vertical The outer frame 6d of the restricting means 6a which is engaged with the locking portion 6b fixed on the uppermost stage of the crosspiece 6 or has a narrow space restriction frame 6a / 1 (see the lower side in FIG. 20) is used as the vertical crosspiece 6 By engaging with the locking portion 6b fixed at the lower stage, it can be transformed into a full-fledged chair-type exercise apparatus by an easy procedure.

Incidentally, an elastic body made of a rubber material in a cylindrical shape as means for improving safety at rest of a user seated on the seat 5/5/1 other than the embodiment introduced in the illustrated example of FIG. as the first strut 3/2 shown in FIG. 19 below the illustrated example of projecting the seat junction 3b at the upper end 30, in the structure having a space 3h inside of the inner wall 32, an outer diameter close to the inner wall 32 In addition to using a rubber-based material, there is a measure of placing a cylindrical elastic member 3d / 6 made larger in diameter than the outer diameter of the elastic member 3d / 1 in the space 3h.
In this case, as a means for giving a little mobility to the safety at rest, a rubber material is used and the elastic member 3d / 7 (lower part in FIG. 19) having a slightly smaller diameter than the elastic member 3d / 6 is used. There is also a measure to place (see) in space 3h.
In a state where the elastic member 3d / 6 is placed in the space 3h, the elastic restoring force of the elastic member 3d / 6 is added to the elastic restoring force of the first column 3/2 main body , and the first column 3/2 is deformed. Because the rigidity against is strengthened, it adapts to the chair for everyday use.
On the other hand, since the elastic restoring force (restorability) that acts at the time of deformation is enhanced, an ellipse or a figure of 8 is drawn with the seat 5/5/1 and the first support column 3/2 inclined in the circumferential direction. It becomes a state unsuitable for implementation of a turning motion.
However, since the outer diameter of the elastic member 3d / 6 and 3d / 7 is made smaller in diameter than the inner diameter of the inner wall 32, as shown in the illustrated example of FIG. 19 lower, elastic members 3d / 6 at the time of twisting movements, or never outer and inner walls 32 of the 3d / 7 are in contact, that no act elastic restoring force with the elastic member 3d / 6 or 3d / 7,.
Therefore, a functional malfunction does not occur in the first support column 3/2 only during the twisting motion, and in such a state, stability at rest is also improved.

Also, except the fourth strut 3/8 showing the third strut 3/6 and 17 upward shown in Figure 16 downward, the third strut 3/9 shown in FIG lower, third strut which is formed in a cylindrical shape the outer wall 31 of moderate downward from the upper end of the 3 compounds with recessed guide 45, 45, 45, the rewritable comprises a projection 3 v / 1 to 3 v / 3 different thickness, the guide 45 to the outer wall 31 of the lower the seat junction 3b / 1 and circumferentially, and a third strut 3/6 shown in FIG. 31 equipped with sliding means 35 nestled in the structure, constituting in combination with the embodiments shown in the illustrated example of FIG. 20 There is also a solution.
In configuration according repulsive force against the rotation direction when twisting motion (elastic restoring force) of Ru is loosely fitted between the inner wall of the mainly driven by the rotation of the seat 5, 5/1 projections swaying 3m, 3m, 3m The elastic restoring force provided in each of the projections 3 v / 1 to 3 v / 3 is mainly responsible.
On the other hand, the repulsive force (elastic restoring force) that resists the tilting (curving and tilting) in the circumferential direction during the turning motion that draws a circle such as an ellipse or a figure of 8 is the elasticity provided by the third support column 3 type. The restoring force and the elastic restoring force provided to the elastic members 3d / 1 to 3d / 3 or the coil spring 3d / 4 placed in the spring insertion hole 3a are used.

Incidentally, the first strut 3 / x or 3 / y shown in the upper part of FIG. 21 can be provided in the same structure as the third strut 3/6 introduced in the illustrated example of FIG. 31, and the protrusions 3 v / 1 to 3 v / 3. If equipped with a (not shown), the repulsive force against the rotation direction during twisting motion as well provided the elastic restoring force primarily responsible individual projections 3 v / 1~3 v / 3 the thickness is different.
In addition, the repulsive force (stability) that resists tilting (curving and tilting) in the circumferential direction during a turning motion that draws a circle such as an ellipse or a figure of 8 is the first strut 3 / x of the structure and The elastic restoring force inherent to 3 / y and the elastic restoring force of the metal-made long thin plate-like leaf spring 3t placed in the leaf spring insertion hole 3s , or the same shape and rubber leaf spring 3t / 1 are carried. .

In this case, fixing the strut container 3c / 1 was introduced in Figure 16 upward immediately below the seat opening 5a, or a seat 5 which is vertical set with integrated third strut 3/6 introduced in FIG lower Similarly, the first support column made by applying the embodiment shown in the illustrated example of FIG. 30 or 31 as compared with the configuration using the third support column 3 which is provided with at least the protrusion 3 v and the seat joint portion 3 b. and type 3, in the configuration using the seat 5 that vertically the post container 3c / 2 directly below the seat opening 5a, thick which functions during twisting motion protrusions 3 v / 1 · middle thickness of the projections 3 v / 2 · projections 3 v / 3 the elastic restoring force with the individual thin (the drag), more promote separation of the elastic restoring force (drag) that function during the first post 3 such tilting of according towards the circumferential direction can do.

Subsequently, the second support 3n introduced in FIG. 22, the second support 3n / 1 introduced in FIG. 7, the second support 3n / 2 introduced below in FIG. 10, or the second support 3n / 3 introduced in FIG. or a second strut 3n / x and 3n / y introduced in the lower part of FIG. 21, and the strut container 3C～3c / 2 described in the first embodiment and Gu設directly below the seat opening 5a / 1 A configuration using the seat 5/1 and modified examples thereof will be described below.
Also, illustrating a modified example of the example shown the arrangement shown in Figure 23 was constructed using the elastic body holding cylinder 3e / 2 or less.

As an example, decomposing a screw tube 2a which is screwed to the screw 3f and the leg 2 which is engraved on the outer wall 31 of the first support 3 downwards shown in Figure 1 of the first embodiment (separation and another conjugated ) was followed, the opening 3a / 2 of the elastic member holding cylinder 3e / 2 while above, a case mounted on the housing space 33/1 from the lower side of the first support 3.
In this case, since the first support column 3 is provided with a plurality of spring insertion holes 3 a and the storage cylinder 33 is provided with a plurality of storage portions 3 e / 1, the elastic body is stored. the first support 3 in a state where the cylinder 3e / 2 is mounted, it is possible to Osame置greater number of resilient members 3d acids or a coil spring 3d / 4 as compared with the conventional.
In such a state, the elastic restoring force acting against the deformation of the first support column 3 can be further increased as compared with the conventional case.

Further, the accommodating portion 3e / 1 made of the same material around the pay置筒33 made of material of the fiber-based or rubber-based having elasticity or flexibility is circumferentially provided with integral, since the housing space 33/1 is made to dimensions within the outer wall 31 and the close fit, elastic holding cylinder 3e / 2 of fitted condition to the outer wall 31 follows the deformation of the first support 3.
In such a state, when the accommodation space 33/1 (elastic body housing cylinder 3e / 2) is fitted to the first support column 3, the opening 3a / 2 is slightly below the upper end of the seat joint 3b (upper end of the elastic body 30). since located, by using the opening 3a / 2 (accommodating portion 3e / 1) elastic member made the length protruding slightly from 3d / 1~3d / 3 or coil spring 3d / 4,, the user These can be taken in and out in the posture seated on the seat 5/5/1.
Incidentally, fitting the first post 3 such other or accommodation space 33/1 to second outer wall 31 of the strut 3n / 2 that circumferentially provided a housing portion 3e only the inner wall 32 (elastic member holding cylinder 3e / 2) to be In this case, the same result is obtained.

In the structure in which the rear surface of the seat 5/1 (directly below the seat opening 5a / 1) is fixed to the upper end of the second support 3n (elastic body 30) shown in FIG. 3e is provided around.
Therefore, the elastic member 3d / 1~3d / 3, or if the coil spring 3d / 4 sets the length of slightly protruding from the opening 3a / 2, seat or without transmural setting of the seat opening 5a / 1 5 / It is advantageous that the elastic member 3 or the coil spring 3d / 4 can be taken in and out from the opening 3a / 2 in a posture in which the user seated on 1 sits without lifting his / her waist from the seating surface 5c / 1.
In such structure, necessarily that it does not required transmural setting of the seating surface opening 5a / 1, that constituted the second strut 3n by using an elastic body 30 does not protrude the seat junction portion 3d at the upper end, housing portion 3e the terms that provided around only the outer wall 31, it is possible to simplify the making of the second strut 3n and seat 5/1. Therefore, the manufacturing cost can be reduced and the manufacturing process can be simplified.

Next, a structure that allows the seat 5/1 to be attached and detached from the upper part of the second support 3n shown in FIG. 22 will be described below.
In this case, by applying the structure of the third support column 3/6 introduced at the bottom of FIG. 16 of the first embodiment, the protrusion swing grooves 3m, 3m, 3m formed in the support container 3c / 2 are applied. the outer wall 31 of moderate downward from the upper end of the elastic body 30 in an arrangement corresponding to the arrangement of laterally set the projection 3 v · 3 v · 3 v , the donut-shaped seat junction 3b on the lower side of the projections 3 v a second strut 3n was circumferentially provided in integral with the outer wall 31 (not shown), fixed struts container 3c / 1 was introduced above the 16 directly below the seat opening 5a / 1 or integrally, by configuring with the seat 5/1 that of, can embody the removable seat 5/1 second strut 3n according.
Incidentally, the seat junction 3b and protrusion 3 v was Katachi設the third strut 3/6 shown in the illustrated example of FIG. 16 which was introduced in the first embodiment integrally with the outer wall 31 using a material rubber is molded, the seat junction 3b and protrusion 3 v according to the second embodiment are also molded integrally with the outer wall 31 using a material rubber.

For example, the second support column 3n including the protrusions 3 v , 3 v , 3 v that are laterally provided on the outer wall 31 moderately below the upper end of the elastic body 30 and the seat joint portion 3 b that is provided below the protrusions 3 v. (not shown), it is assumed configuration using a post container 3c / 1 to fixed directly below the seat opening 5a / 1 seat 5/1 to or integrated.
In the configuration according, according to a second post 3n during twisting movement around an axis, each projection drag to the rotation direction of the user sitting on the seat 5/1 biases in the reverse direction was made in the material of the rubber-based 3 It is mainly responsible for the elastic restoring force (stability) provided by v .
On the other hand, the circumference or the like during the turning movement to draw the figure eight, the second strut 3n tilting of drag (the curved-tilt) direction acting in the opposite direction (stress) is shaped cylindrical, made of a material of rubber according and the elastic body 30, in addition to the elastic restoring force included as a characteristic in the second strut 3n body that consists of a plurality of accommodating portions 3e was peripherally provided with integrated in the outer wall 31 (Stability), housed in the housing portion 3e elastic members 3d such that location, or elastic restoring force provided in the coil spring 3d / 4 (Stability) plays.
Thus, the elastic restoring force against the rotation direction of the user at the time of twisting motion is mainly to each of the projections 3 v, original return (resilience-righting) resisting deformation during the pivoting movement and the second strut elastic members 3d such that Osame置the originally provided elastic restoring force and housing portion 3e to 3n body, or generally allowing Rukoto is shared to the elastic restoring force included as a characteristic in the coil spring 3d / 4.

Further, according the fact that the seat 5/1 can detachable from the second strut 3n according in the configuration, the upper surface inner edge portion of the projecting portion 44 with diameter corresponding to the diameter of the inner ring 37 as shown in the illustrated example of FIG. 24 or 29 post a seat junction 3b / 1 which projects, as well as attached sliding means 35 (ball bearings) to the second strut 3n, the outer housing 39 having an inner surface 41 of the inner diameter of outer surface 41a and fitting the outer ring 36 in By using the column container 3c / 2 formed at the lower end of the container 3c / 1, the rotation of the seat 5/1 during the twisting movement becomes smoother.
In the configuration according until each projection 3 v abuts the inner wall surface of the projection swaying 3m respectively, elastic members 3d acids were Osame置the second strut 3n and accommodating portion 3e, or a coil spring 4d is deformed according The elastic restoring force (stress / restorability) that occurs when returning to the original shape against this does not act.
Therefore, as compared with the structure without attaching a seat junction 3b / 1 and sliding means 35 and strut container 3c / 2, an elastic restoring force against the projections 3 v respectively deformed during twisting movement (stress-Stability) When, sharing is further promotion of the elastic restoring force generated against the deformation of the second strut 3n and the elastic member 3d acids or coil spring 4d, according to late with respect to the deformation of the projections 3 v (stress-Stability) Is done.

Further, the second support post 3n such openings 3a / 2 and 3a / 5 opened in the housing portion 3e or upper end of the plate spring accommodating portion 3s / 1 was provided around the outer wall 31 of the (elastic body 30, 30/1) of It is disposed moderate downward from the upper end of the elastic body 30 or 30/1, as is shown in the illustrated example.
Therefore, the same number of guides 45 are recessed in the outer wall 31 extending from the upper end of the elastic body 30 to the upper side of the sliding means 35 in the arrangement corresponding to the arrangement of the protrusion swing grooves 3m, 3m, and 3m. The locking protrusions 46 to be formed are formed at the bottom, and the same number of the three types of the thick protrusions 3 v / 1, the medium thickness 3 v / 2 and the thin wall 3 v / 3 are formed as the guide 45, and the inner ring 37 the seat junction 3b / 1 of the projecting portion 44 projecting from having the same diameter and provided around the outer wall 31 of the guide 45 downwardly, the projection 3 v / 1~3 v / 3 the guide 45 Not engaging By attaching the sliding means 35 to the outer wall 31 in this state, it is possible to transform all the second support columns 3n (partially not shown) into the same structure as the embodiment shown in the illustrated example of FIG. 30 or 31. .
The second strut 3n such that metamorphic structure according can be constructed using the (partially not shown), a seat 5/1 having a post container 3c / 2 directly below the seat opening 5a / 1 become.

Further, in the structure shown in the illustrated examples of FIGS. 30 and 31, during the turning motion for drawing an ellipse or a figure of 8 or the like , the third column 4 or the fourth column 3n is tilted (inclined / curved) in the circumferential direction. ) Is not only variable or adjustable by increasing / decreasing the number of elastic members 3d or coil springs 3d / 4 that store elastic restoring force acting in the housing portion 3e, but also the physical strength of the user or desired exercise strength projection thickness according to 3 v / 1, or 3 v / 2, or by replace the 3 v / 3, drag acting in the direction opposite to the rotation direction of the user during twisting movement (protrusion 3 v / 1 It is possible to adjust and to change the elastic restoring force / stability of ˜3 v / 3.
Furthermore, according case of a non-engaging projections 3 v / 1~3 v / 3 to the guide 45 in the structure, chair normal swivel chair added a swirling motion (rotational motion) features toward the circumferential direction It can also be modified into a type exercise apparatus.

Further, in the case of the four-post 3n / 5 or 3n / 7, the accommodating portion 3e, which opened the opening 3a / 2 at the upper end from the point where the provided around the outer wall 31, slightly elongated than the full length of the housing portion 3e made elastic member 3d / 1 (see FIG. 9), or coil spring 3d / 4 by adopting, user seat surface 5c into and out of them from the accommodation section 3e which is provided around the outer wall 31 side / 1 can be performed in a sitting position. Therefore, the operation | work at the time of the fine adjustment of the elastic restoring force produced when the 4th support | pillar 3n / 5 or 3n / 7 tilts becomes easy.
Incidentally, in the illustrated example of FIG. 31 the guide 45 is recessed in three places of the outer wall 31, as well as adding a further guide 45, the projections 3 v / 1 to 3 v / 3 of the extension and expansion Guides 45 By providing the protrusion rocking groove 3m (not shown) corresponding to the position of the movement, the choice of the acting amount of the elastic restoring force for reversing the rotation of the user seated on the seat 5/5/1 during the twisting motion, and the guide the number of the projections 3 v / 1~3 v / 3 for fastening to 45 or the thickness of the projections 3 v / 1~3 v / 3, , or fastening with respect to the projections 3 v / 1~3 v / 3 of the guide 45 More choices in combination of number and wall thickness.

On the other hand, the second strut 3n / 2 shown in FIG. 10 below, and integrated with the inner wall 32 of the elastic body 30, a number of the receiving portion 3e, which opened the opening 3a / 2 are circumferentially on the upper end, second strut 3n / 3 shown in FIG. 8 or FIG. 11 upward is integrated with both the outer wall 31 and inner wall 32 of the elastic body 30, a number of the receiving portion 3e, which opened the opening 3a / 2 at the upper end It is installed around.
On the other hand, the second strut 3n / x shown below the right side of FIG. 21, integral with the outer wall 31 of the elastic body 30, a number of leaf spring accommodating portion 3s / 1, which opened the opening 3a / 5 at the upper end The second support 3n / y shown on the lower left side of the figure is integrated with both the outer wall 31 and the inner wall 32 of the elastic body 30 , and an opening 3a / 5 is opened at the upper end. The leaf spring accommodating portion 3s / 1 is provided.
In these second illustrated embodiment relates to struts 3n such, the opening 3a / 2 or 3a / 5 elastic body 30 or 30 was opened in the housing portion 3e or upper end of the plate spring accommodating portion 3s / 1 was provided around the outer wall 31 side / 1 from the point disposed below the upper end, the elastic from the accommodation portion 3e or leaf spring accommodating portion 3s / 1 was provided around the outer wall 31 side member 3d acids or coil spring 3d / 4, or leaf spring 3t or The operation of increasing / decreasing these numbers by taking 3t / 1 in and out can be performed without difficulty.
However, housing portion 3e were provided around the inner wall 32 side or opening 3a / 2 or 3a / 5 elastic member 3d acids or coil spring 3d / 4 from opened to the upper end of the plate spring accommodating portion 3s / 1, or plate, In order to increase or decrease the number of the springs 3t or 3t / 1 by inserting or removing them, it is essential to penetrate the seat surface opening 5a / 1.

For example, the upper end of the second strut 3n / 2 the upper end of the elastic body 30 constituting a structure fixed directly below the seat opening 5a / 1 a, housing portion 3e which is provided around the inner wall 32 introduced in the lower part of FIG. 10 opening 3a / 2 to the position (accommodating portion 3e of the full-length or less of the total length of the elastic body 30 from the screw 3f top to the upper end) arranged at the upper end of the elastic body 30 or 30/1, the elastic member 3d / 1~3d / 3 or the coil spring 3d / 4 is set to an overall length that protrudes approximately 10 mm to 20 mm from the opening 3a / 2, it is essential to set the thickness of the seating surface 5c / 1 to at least 20 mm.
On the other hand, in this structure, in contact with the end point 3k with placing opening 3a / 2, located at the upper end of the housing portion 3e which is provided around the inner wall 32 from the upper end of the elastic body 30 or 30/1 to 30mm approximately downward In this state, by using the elastic members 3d / 1 to 3d / 3 or the coil springs 3d / 4 which are made to have a full length whose end is located about 10 mm below the upper end of the elastic body 30, the seat opening 5a / 1 is removed. Can be taken in and out without difficulty. In such a structure, it is possible to cope with a seat 5/1 having a seat surface 5c / 1 made thin.
On the other hand, the first fixed attachment means 3i nature to coalesce with attachment means 3i fixedly provided at at least one end of the sampling member 3d / 5 was introduced in Figure 18 embodiment the at least one end to Rutotomoni accommodating portion 3e There is also a measure using elastic members 3d / 1 to 3d / 3 or coil springs 3d / 4 which are made slightly shorter than the full length.

As a specific example, the second strut 3n / 1 was introduced in the second post 3n or 7 introduced in FIG. 22, it has circumferentially provided a housing portion 3e only the outer wall 31 of the elastic body 30 constituting these posts and As in the embodiment shown in the illustrated example of FIG. 9, when one end of the elastic member 3 d / 1 is in contact with the end point 3 k and the other end is made to have a full length that appropriately protrudes from the opening 3 a / 2, Coupled with the fact that the opening 3a / 2 provided in the accommodating portion 3e provided around the outer wall 31 is opened moderately downward from the upper end of the elastic body 30, it is not essential to penetrate the seat opening 5a / 1.
In such structure, the pivoting movement draw like-shaped oval, or 8, or when performing an oscillating motion to linear motion back and forth lateral or oblique direction, circumferential to the outer wall 31 side in a posture in which the user is seated on the seating surface 5c The elastic member 3d or the coil spring 3d / 4 to be accommodated in the accommodating portion 3e provided is increased or decreased to act against the tilting (curving / inclining) of the second column 3n or 3n / 1 in the circumferential direction. Workability when changing or adjusting the elastic restoring force is improved.

On the other hand, in the case of the second support column 3n or 3n / 1, since the accommodating portion 3e for accommodating the elastic members 3d or the coil spring 3d / 4 is provided only around one wall surface of the outer wall 31, the rotation of these support columns when tilting direction adjusting an elastic restoring force against the (bending direction) or variable, of time, receiving unit 3e choices of resilient members 3d acids or coil spring 3d / 4 of paid置先is provided around the outer wall 31 It is limited to.
Further, in the second support column 3n / 2 introduced in the lower part of FIG. 10, since the accommodating portion 3e is provided only around one wall surface of the inner wall 32 of the elastic body 30, it resists the tilting direction (curving direction) during turning. when adjusting the elastic restoring force, choices of the elastic member 3d acids or coil spring 3d / 4 of paid置先it is limited in the receiving section 3e which is provided around the inner wall 32.

On the other hand , in the second support column 3n / 3 shown in the illustrated example of FIG. 8, the accommodating portion 3e having the same inner dimension is provided on both the outer wall 31 and the inner wall 32 of the elastic body 30.
Therefore, it is clear that the number of peripheral portions of the accommodating portions 3e with respect to the second struts 3n / 3 exceeds the number of peripheral portions of the accommodating portions 3e with respect to the second struts 3n, 3n / 1, or 3n / 2.
Therefore, the elastic member 3d or the coil spring 3d / 4 is increased or decreased in order to adjust or change the elastic restoring force against the tilting (curving) direction of the second column 3n or 3n / 1 or 3n / 2 , or The options for changing the arrangement and placing it in the accommodating portion 3e provided around both the outer wall 31 and the inner wall 32 are diversified.

Specifically, the elastic restoring force acting on the second time post 3n / 2 modifications of the second strut 3n and 3n / 1 or the inner wall 32 only in the receiving section 3e has circumferentially provided to circumferentially the housing portion 3e only the outer wall 31 In the case of the second support column 3n / 3, the housing 3e is provided on both the outer wall 31 and the inner wall 32, so that the absolute number of the elastic members 3d or the coil springs 3d / 4 can be reduced. since the increase, the adjustment range of the elastic restoring force acting on these struts (drag-stress) further spread.
In such structure, while Osame置the second strut 3n or elastic member 3d acids or coil spring 3d / 4 for all receiving portion 3e, which is circumferentially provided on 3n / 2, an elastic restoring force acting upon deformation ( Compared to (drag / stress), the elastic restoring force acting upon deformation of the second column 3n / 3 in a state where the elastic members 3d or the coil springs 3d / 4 are placed in all the accommodating portions 3e is further enhanced. .
Further, in the case of the second support 3n / 3 compared to the second support 3n / 1 or 3n / 2, the difference from the lower limit to the upper limit of the number of the elastic members 3d or coil springs 3d / 4 increases. Further, fine adjustment of the elastic restoring force can be performed more precisely.
Therefore, various users can adjust to a state closer to the desired elastic restoring force each time, and can be changed to a significantly different elastic restoring force.

For example, an elastic body 30 made of a rubber material rich in elasticity, a vertically long bag shape using the same material, an opening 3a / 2 at the upper end, and an end point 3k at the lower end elastic in all accommodation portion 3e provided in the second support column 3n / 3 shown in Figure 8 the housing portion 3e provided secured to both the outer wall 31 and inner wall 32, or which is circumferentially provided with integrated member 3d / 1~3d / 3 or assume a state unpaid location coil spring 3d / 4.
In this case, similarly to the housing portion 3e which is provided around the one of the second outer wall 31 of the strut 3n or 3n / 1 or 3n / 2 or the inner wall 32, and circumferentially provided on both the outer wall 31 and inner wall 32 since the accommodating portion 3e and the elastic body 30 is made using a material rubber, the housing portion 3e circumferential設数many minutes, the same state of the second strut 3n or 3n / 1 or 3n / 2 As a characteristic , it exhibits a slightly stronger or similar elastic restoring force compared to the elastic restoring force (stability) exhibited during deformation.

Incidentally, in the case of using the second strut 3n / 3, a seat 5/1 having a post container 3c / 2 directly below the seat opening 5a / 1, the guide 45, 45, 45 which is recessed in the outer wall 31 , the projection 3 v / 1 to 3 v / 3 made in the thickness of the three different while Katachi設the locking projections 46 on the bottom surface, consisting of a seat joint 3b / 1 Metropolitan comprising sliding means 35 30 Alternatively, the embodiment introduced in the illustrated example of 31 and a gymnastic exercise in which a plurality of types of restriction means 6a having restriction frames 6a / 1 in different spaces are attached to the engaging portions 6b of the vertical beam members 6 welded in multiple stages. It is most preferable in the second embodiment that does not use power such as a motor to be configured by combining the example shown in FIG.
In the configuration according for weight from the seat 5/1 direction due user's body weight, with the second strut 3n / 3 or the fourth post 3n / 7 is stave off falling into unduly flattened to dysfunctional utilization The safety of the person, the elastic restoring force acting against the rotational direction of the seat 5/1 during the twisting movement, and the second strut 3n / 3 or the fourth strut 3n during the swiveling movement that draws various circumferences It is advantageous that the elastic restoring force acting against the tilt direction of / 7 can be individually adjusted or varied.

Subsequently, a seat to the embodiment introduced in the illustrated example, the tool set fixedly or in integrated directly below the seat opening 5a / 1 strut container 3c / 2 illustrated in FIG. 24 in FIG. 9 5 / 1, a seat junction 3b / 1 was provided around the elastic member 30 or the outer wall 31 of moderate downward from the upper end of the third column 3 include, introduced in FIG. 30 and 31, while fitted to the outer wall 31 the protrusion 44 sliding means 35 that will be put on (see FIG. 25), the elastic body 30 in an arrangement corresponding to the arrangement of the projections swaying 3m · 3m · 3m or third slide from the upper end of the post 3 such, Guide 45, 45, 45 which is recessed in the outer wall 31 subjected to the upper portion of the unit 35 (see FIG. 31), Katachi設to Rutotomoni three different meat locking projections 46 engaged with the guide 45 on the bottom the third post 3 such consisting made in thickness (width) projections 3 v / 1 to 3 v / 3 Metropolitan or the The effect of the structure using struts 3n compound described below.

For example, in the fourth strut 3n / 7, since it has circumferentially provided a housing portion 3e on both the outer wall 31 and inner wall 32 of the elastic body 30, circumferentially provided a housing portion 3e on one of the outer wall 31 or inner wall 32, the other fourth compared to post 3n such, the total number of the receiving portion 3e is you increase.
Accordingly, a fourth support column 3n / 7, with the user on the seat surface 5c / 1 configuration using a seat 5/1 having a post container 3c / 2 directly below the seat opening 5a / 1 is seated oval or when performing a swirling motion to draw such a figure eight, the elastic member 3d acids or options simultaneously paid registered number when placement locations are diversified when Osame置coil spring 4d becomes enriched in the housing portion 3e.
Therefore, users of different strength regardless of age gender, or user against desired exercise intensity in the context of each time (the elastic restoring force, stress), housing part on one of the outer wall 31 or inner wall 32, compared to 3e to the fourth strut 3n such that circumferentially provided, in the fourth strut 3n / 7 according a can be adjusted elastic restoring force against the time of tilting toward the circumferential direction (Stability) even more finely, The advantage is that it can be varied more greatly.

Further, the guide 45 which is recessed in three places of the outer wall 31, shown in the illustrated example of FIG. 30 and 31 the wall thickness (width) constituted the different projections 3 v / 1 to 3 v / 3 disengaged freely When the user seated on the seat 5/1 of the embodiment performs a twisting motion, the seat 5/1 is removed from the fourth column 3n / 5 or 3n / 7, and the protrusions 3 v / 1 to have different thicknesses (widths). 3 v / 3 is appropriately selected and engaged with each guide 45, or the protrusions 3 v / 1 to 3 v / 3 are engaged with each guide 45 as a combination of different thicknesses, thereby twisting motion sometimes subtly adjust the elastic restoring force of reversing the rotation of the seat 5/1, or may be significantly variable.
In such a structure, when a user sits on the seat 5/1 and performs a twist exercise, the user has various physical strengths regardless of age and gender , or the exercise intensity desired by the user in each situation (elastic restoring force) projection thickness suitable (width) 3 v / 1~3 v / 3 select, or by fastening the respective guide 45 in combination, the user of times sitting on the seat 5/1 during twisting motion adjusting or varying the Chikashii state the request of each of the projections 3 v / 1~3 v / 3 of the individual elastic restoring force provided in a variety of user acting against the movement is realized.
Further, when the elastic restoring force against the tilting direction of the fourth column 3n / 5 or the fourth column 3n / 7 is slightly biased or reduced during the turning motion, the outer wall 31 is seated on the seat 5/1. since suffice from the accommodating portion 3e, which is circumferentially provided on the side in the fine adjustment of the increasing or decreasing the elastic member 3d acids or coil spring 4d, convenience is improved as compared with the other fourth strut 3n acids.

Figure immediately below the seat opening 5a / 1 shown in the illustrated example of 24 or 29, a seat 5/1 having a post container 3c / 2, either one of the accommodating portion 3e outer wall 31 or inner wall 32, or outer wall 31 and in the configuration using the fourth strut 3n such that circumferentially provided on both of the inner wall 32, through the opening 3a / 2, which opened on an upper end of the housing portion 3e, the ends of the elastic member 3d acids or coil spring 4d 10 mm to It preferred you to set the length that protrudes approximately 20 mm.
In such structure, the housing portion 3e which is provided around the outer wall 31 side while the posture which a user is seated, it is out of the elastic member 3d acids or coil spring 4d, during the fourth tilting strut 3n compound according ( This eliminates the trouble of getting up from the seat 5/1 when fine-tuning the elastic restoring force acting during deformation.

On the other hand, in the structure in which the upper end of the elastic body 30 or 30/1 is fixed immediately below the seat opening 5a / 1, the elastic members 3d having a total length slightly shorter than the total length of the accommodating portion 3e provided around the outer wall 31 or the inner wall 32 are provided. Alternatively, it is preferable to adopt a configuration using the coil spring 4d, the extraction member 3d / 5 and the attaching means 3i introduced in the illustrated example of FIG. 18 of the first embodiment.
By the way, since when using the seat 5, 5/1, which was formed through the seat opening 5a · 5a / 1 as become not of everyday use chair gymnastics at the time only plays the role of sitting in a circle, such as hemorrhoids and anal prolapse, buttocks A good sitting comfort can be provided even for users with chronic illness.

Further, attached or resilient restricting means 6a having a locking portion 6b which is fixed in the vertical direction of the multi-stage vertical crosspieces 6 introduced in the example shown in FIG. 9, the regulating frame 6a / 1 of several space size member 3d acids or coil spring 4d or second by multiple Osame置the bar or plate of rigid with leaf springs 3t equivalent external dimensions in the spring insertion hole 3a or accommodating portion 3e or leaf spring accommodating portion 3s / 1, The rigidity with respect to the deformation of the first column 3 or the second column 3n is improved.
Further, in the case of the second support column 3n or 3n / x in which the accommodating portion 3e or the leaf spring accommodating portion 3s / 1 is provided only on the outer wall 31, the diameter is slightly smaller than the inner diameter of the space 3h introduced in the illustrated example of FIG. There is also a measure for improving the stability of the second support columns 3n at rest by placing the elastic member 3d / 6 made in the above in the space 3h.

By taking the above measures, the user sitting on the seat 5-seat 5/1 was constructed using the first embodiment was constructed using the first post 3 acids, or a second strut 3n acids Safety is maintained when the chair 1 capable of gymnastic exercise or the chair 1/1 capable of gymnastic exercise according to the second embodiment is used as a chair for everyday use.
Note that when Osame置elastic member 3d / 6 in the space 3h, you enhance the elastic restoring force against the tilting direction of the second strut 3n or 3n / x during turning motion to draw various circumferential (Stability) is .
However, since the outer diameter of the elastic member 3d / 6 compared to the inner diameter of the space 3h it is made smaller in diameter, the elastic restoring force you to enhancement not acting against the rotating direction of the user at the time of twisting motion.
Therefore, it is possible to save the user from changing the elastic restoring force acting on the second column 3n or 3n / x away from the seat 5/1 when performing the twisting motion.

When the first support column 3 / third support column 3 or the second support column 3n / fourth support column 3n of the first and second embodiments described above is used as a chair for daily use and exercise, the third support column Three types or guides 45, 45, 45 recessed in the outer wall 31 extending from the upper end of the elastic body 30 to the sliding means 35 or the sliding means 35/1 or the sliding means 35/2, and are engaged with these guides 45 The third support column 3 or the like, which is provided with a projection 3 v / 1 to 3 v / 3 formed with different thicknesses and a seat joint 3 b / 1 including a sliding means 35 or the like, with the locking projection 46 formed at the bottom. a fourth support column 3n such, it is desirable to incorporate a configuration using a seat 5-5/1 having a post container 3c / 2 directly below the seat opening 5a - 5a / 1.
Or, post container 3c / 3 was horizontally provided projections swaying 3m, 3m, 3m of arrangement corresponding to the arrangement of the inner set to Rutotomoni guide 45, 45, 45 the outer housing 39 to the upper side to the lower side of the outer seat 5 comprises a (see FIG. 25, 26) or a seat 5/1, the third column 3 such or fourth post 3n such that ingredients Bei seat junction 3b / 1 and the guide 45 includes a sliding means 35 such It is desirable to adopt a configuration using.
Alternatively, Katachi設the guide 47, 47, 47 at the upper end, the seat junction 3b / 3 projecting from the projecting portion 44 on the inner side of the edge (see FIG. 28) the outer wall 31 two turns of moderate downward from the upper end a first post 3 such or second strut 3n such that setting was made with locking projections 46 which engaged with Rutotomoni different thickness to Katachi設the bottom the guide 47 protrusions 3 v / 1 to 3 v / 3, post fitting hole 3c / 6 to the inner set of outer housing 39 to Rutotomoni, post container 3c was horizontally provided projections swaying 3m arrangement corresponding to the outer periphery of the lower end to the arrangement of the guide 47 / 4 it is desirable to incorporate a configuration using the seat 5 or the seat 5/1 comprises (see Figure 27).
In such a structure, the seats 5 and 5/1 are attached by forming the protrusions 3 v / 1 to 3 v / 3 or the protrusion swinging grooves 3 m at the total height slightly protruding from the upper end of each protrusion swinging groove 3 m. it is in and that state, it is possible to disengage the protrusions 3 v / 1~3 v / 3 according the respective guide 47.
Therefore, in adjusting or varying the elastic restoring force generated against the rotation direction of the user at the time of twisting motion, it is possible to save the trouble of removing the seat 5-5/1.

Incidentally, in the configuration using the second column 3n / 3 or 3n / y or the fourth column 3n / 7 , the accommodating portion 3e or the leaf spring accommodating portion 3s / 1 is provided around both the outer wall 31 and the inner wall 32 of the elastic body 30. Has been.
Thus, as compared with the housing portion 3e or plate peripheral設箇plants spring receiving portion 3s / 1 (wall surface) of the second-fourth strut 3n such other that will be limited to either of the outer wall 31 or inner wall 32, the second for post 3n / 3 or 3n / y or fourth post 3n / 7, housing portion 3e or elastic member 3d acids or coil spring 3d / 4 to Osame置the plate spring accommodating portion 3s / 1,, or a leaf spring 3t or Since the amount can be increased by 3t / 1, it is suitable for use in situations where rigidity is required regardless of whether it is operating or stationary.

As a specific example, the guide 45 engaged with the projections 3 v / 1~3 v / 3 made in different thickness with removal is freely, in FIG. 30 of the seat junction 3b / 1 Metropolitan comprising sliding means 35 such a fourth support column 3n / 5 or 3n / 7 shown in the illustrated example, the legs 2/1 with recessed longitudinal crosspieces joining hole 6/1 at a plurality of locations of the upper surface, the locking portion 6b in the vertical direction of the multi-stage the longitudinal crosspieces 6 welded, a case constituting the embodiment shown in the illustrated example of FIG. 9 consisting of three regulating means 6a having a regulating frame 6a / 1 of different spaces.
For example, the fourth case of post 3n / 7 chair 1/1 that can exercise constructed weight heavy user with uses as chair everyday use, many were provided around both of the outer wall 31 and inner wall 32 of By accommodating a large number of elastic members 3d or coil springs 3d / 4 in the housing portion 3e, the repulsive force acting when these columns are deformed is increased, and at the same time, the interior of the housing portion 3e is in a high density state. Therefore, the rigidity in the vertical and horizontal directions is improved.

In such a state, when the user sits on the seat 5/1 and eats or reads, the user holds a substantially stationary posture, and the flatness of the fourth support 3n / 7 by weighting of the user's weight, It is possible to limit the tilting (refraction and bending) of these columns by the user's action to a certain extent.
Furthermore, it is engaged with the locking portion 6b which is welded to the top of the fourth post 3n / 7 regulating frame 6a / 1 a narrow space after removal of the seat 5/1 facilities from the regulating means 6a the vertical crosspieces 6 As a result, the flatness and the degree of refraction (curving) of these columns are further limited, and the safety when the user sitting on the seat 5/1 performs an inadvertent operation is further improved.

Then, opening when the fitted elastic body 30/1 from the lower side, a tubular paid置筒33 which opened the housing space 33/1 to outer wall 31 and the close fit, the openings 3a / 2 at the upper end the end point 3k provided to Rutotomoni lower end, housed置筒33 around the surrounding annular circumferentially provided the elongated elastic member holding cylinder 3e / 2 indicated above in Figure 23 comprising a bag-shaped accommodating portion 3e / 1 at the Illustrative examples and application examples (modifications) will be described below.

Subsequently, a fourth support column 3n / 7, introduced in the illustrated example of FIG. 30 or 31, and a screw tube 2a of the screw 3f and screwed that engraved on the outer wall 31 of the moderately upward from the lower end of the elastic body 30, the upper surface longitudinal crosspieces 6 and three different sizes made of the legs 2/1 and the vertical direction of the locking portion 6b which is welded to the multi-stage consisting of a vertical crosspieces joining hole 6/1 Metropolitan was recessed in a plurality of locations Gymnastics shown in the illustrated example of FIG. 9 constituted by regulating means 6a comprising a plurality of horizontal crosspieces 6c connecting the Rusotowaku 6d is engaged with the regulating frame 6a / 1 and the locking portion 6b having a space Various functions provided in the embodiment of the chair 1/1 that can be used and various advantages provided by these functions will be described below.

For example, the fourth post 3n / 7 compared with the four-post 3n / 5 or 3n / 6 to circumferentially the housing portion 3e on one of the outer wall 31 or inner wall 32 (see FIG. 29, 30) (FIG. 11 upper · in Figure 30 reference), since it has circumferentially provided a housing portion 3e on both the outer wall 31 and inner wall 32, and adjusting the elastic restoring force acting in the opposite direction during the tilting of the fourth strut 3n / 7 more subtly, It can be made much more variable.
In addition, the seat 5/1 is configured to be detachable by the attachment of the support container 3c / 2, the seat joint 3b / 1 including the sliding means 35 and the guide 45 of the elastic body 30 ( fourth support 3n type). and provided on the outer wall 31, provided with a projection 3 v / 1 to 3 v / 3 of wall thickness three different, since it has engaged detachably a guide 45, a seat within a certain range during twisting motion it is possible to variably or modulate the intensity of the elastic restoring force acting against the direction of rotation of 5/1 by replace the different thickness of the projections 3 v / 1~3 v / 3.
In this case, reducing means for fastening to the wall thickness by combining different projection 3 v / 1~3 v / 3 each guide 45, the engaging speed of the protrusions 3 v / 1~3 v / 3 with respect to the guide 45 means In particular, the latter means is easy and effective in reducing the elastic restoring force acting against the rotational direction of the seat 5/1.

The guide 45 is recessed in three places of the outer wall 31 of the over the upper sliding means 35 from the upper end of the third column 3/6 or fourth post 3n such in the illustrated example of FIG. 31.
However, by various of the thickness of the projections 3 v such as to add more projections swaying 3m and the guide 45, regulating or the intensity of the action of the elastic restoring force against the rotation of the user at the time of twisting motion More options when changing.
In such a structure, the number of the recessed portions of the guide 45 is increased, and the protrusion rocking grooves 3m arranged in accordance with the recessed portions and the number of the recessed portions are horizontally disposed from the inner wall surface 3c / 5 of the support container 3c / 2 toward the inside. be Rukoto is preferable.
In this case, the distance between the outer wall surface each other of the adjacent projections swaying 3m, while arranged to be equal to the distance between the inner wall surface each other of the projections swaying 3m, the arrangement of the projections swaying 3m there is also means for adding a guide 45 of the corresponding positioned recessed in the third outer wall 31 of column 3/6 or fourth post 3n acids. (Not shown)

In addition to such a structure, in the embodiment of the chair 1/1 capable of performing the exercise shown in the illustrated example introduced in FIG. 9, the locking portion 6 b welded in the vertical direction of the vertical cross member 6 and the locking portion 6 a. A restricting means 6a provided with restricting frames 6a / 1 of three different spaces configured to be freely disengaged from each other is attached.
Therefore, when the user seated on the seat 5/1 performs a swinging motion in the front / rear / right / left or diagonal direction, the seat 5/1 is removed , or the fourth column 3n / 7 (screw 3f) is attached to the leg 2 / After being removed from 1 (screw tube 2a), the outer frame 6d of the restricting means 6a provided with the restricting frame 6a / 1 in a narrow space is engaged in advance with the engaging portion 6b disposed on the upper stage of the vertical beam member 6. The angle at which the fourth column 3n / 7 tilts (tilts / curves) in the circumferential direction and the swivel area are narrowed.
Therefore, it is advantageous that the user himself / herself can safely perform a swinging motion that repeats linear movement in the front / rear, left / right , or diagonal directions, and a swivel motion that draws various circumferences without achieving safety.

Further, the locking portion 6b disposed on the upper stage, as an advantage when Ru is engaged the regulating means 6a (outer frame 6d) of restriction frame 6a / 1 a narrow space is provided, the elastic member 3d acids or coil spring 3d / 4 regardless of the pay stationary state of, if the weight heavy user is sitting on the seat 5/1 attached to the top of the fourth post 3n / 7, flat of the fourth strut 3n / 7 above (the size is flattened deformed )) Exceeds the size of the restriction frame 6a / 1, the flatness (deformation) above the fourth support column 3n / 7 remains at the upper part of the restriction frame 6a / 1.
In such a state, the locking portion 6b is welded to the vertical beam member 6, the vertical beam member 6 is fitted into the vertical beam member joining hole 6/1, the outer frame 6d and the horizontal beam member 6c, Since the restriction frame 6a / 1 is joined to each other by welding, the load on the seating surface 5c / 1, that is, the weight of the user is automatically determined from the restriction frame 6a / 1 to the crosspiece 6c to the outer frame 6d to locking. in order parts 6b~ longitudinal crosspieces 6 longitudinal crosspieces joining hole 6/1 finally propagated to the legs 2/1.
In this case, the starting point corresponding to the start point 3w when tilted in the circumferential direction during turning of the fourth strut 3n / 7 (see FIG. 2) inside the regulating unit 6a locking portion 6b and the (outer frame 6d) is engaged wear It changes to the vicinity of the upper part of the restriction frame 6a / 1 located at the top, and as a result, the fourth support column 3n / 7 with the seat 5/1 attached to the upper part has a small circle with the vicinity of the upper part of the restriction frame 6a / 1 in a narrow space as an axis. a function of turning while tilted (inclined-curved) in a circumferential direction, the function of the seat 5/1 to dynamic lateral twice sliding means 35 as an axis, and a function as a chair everyday use are preserved.

For example, an elastic member 3d / 1 to 3d / 3 , or a coil spring 3/4 is not placed in the accommodating portion 3e, or the seat 5/1 attached to the fourth column 3n / 7 in a state where the number of placement is small, Assume a case where a heavy user is seated and performs a turning motion in which an ellipse or a figure of 8 is drawn , or a swinging motion that moves straight forward, backward, left, right, or diagonally.
In this case, the locking portion 6b which is fixed to the top of the vertical crosspieces 6a, in Rukoto is engaged in advance regulating means 6a (outer frame 6d) of restriction frame 6a / 1 a narrow space is provided, use who are not required to refrain from their operation consciously with the origin at the time of the fourth post 3n / 7 comprising a seat 5/1 is tilted (inclined-curved) toward the circumferential direction, the range of pivoting regulations It is limited according to the area occupied by the space of the frame 6a / 1.

In such a state, when the fourth column 3n / 7 is tilted (inclined / curved), the starting point at the time of turning is near the lower side of the restriction frame 6a / 1 located inside the locking portion 6b fixed at the uppermost stage. At the same time as the transition to (see FIG. 20), the region where the user can sit in the seat 5/1 can perform a turning motion because the region in which the vehicle can turn is limited by the restriction frame 6a / 1 in a narrow space. Naturally restricted. Therefore, it is advantageous that an unexpected accident such as a fall from the seating surface 5c / 1 can be avoided in advance.
In such a configuration, various users select the restricting means 6a having the appropriate space restricting frame 6a / 1 according to the circumstances or conditions such as their own weight and physical strength, and also set the outer frame 6d to an appropriate location ( in Rukoto is engaged with the locking portion 6b which is disposed at a height), physical strength is weak users and body weight are safe preservation of heavy users.
Furthermore, by removing the restricting means 6a provided with the restrictive frame 6a / 1 in the narrow space , or replacing it with the restricting means 6a provided with the restrictive frame 6a / 1 in the wide space, a user who has a strong physical strength who desires a strong exercise. This can be dealt with suitably.
