First Embodiment
Hereinafter, a first embodiment of a standing riding type exercise apparatus 1 according to the present invention will be described with reference to the drawings.
The embodiment to be described below is described by exemplifying a ski-type standing-ride type exercise apparatus 1, but this is an example embodying the present invention, and the embodiment of the present invention will be described with reference to the example. It does not limit the configuration. That is, this technique is applicable to any exercise device that stands on a board and rides.

Moreover, in order to make it easy to read regarding FIGS. 1-6, one part is abbreviate | omitted and drawn.
Further, in the following description, the direction shown by the arrow in FIG. 1 is taken as the direction when explaining the standing riding type exercise apparatus 1. This corresponds to the direction viewed from the user M who got on the stand-up type exercise apparatus 1. In addition, about these directions, it has shown suitably using the arrow in drawing.
The stand-up type exercise apparatus 1 according to the present invention realizes an operation similar to a ski operation in which a ski is swung from side to side on a snow surface to slide. In particular, the standing riding type exercise apparatus 1 according to the first embodiment is a ski operation (so-called so-called ski operation) in which the ski is swung sideways little by little in accordance with the unevenness on the snow surface (lump slope) formed in the unevenness shape. , And mogul).

That is, the standing riding type exercise apparatus 1 of the present invention can be said to be a "ski-type exercise machine".
The stand-up type exercise apparatus 1 is provided below the boarding section 3 with the boarding section 3 on which the user M can stand and board, and reciprocates the boarding section 3 back and forth and to the left and right around the vertical axis. A rocking mechanism 10 that generates a twisting motion by rocking, a drive mechanism 11 that drives the rocking mechanism 10, and the rocking mechanism 10 and the drive mechanism 11 can be mounted on the floor surface F. A case body 2 and a pair of gripping bars 6 provided on the front side of the case body 2 and gripped by the user M are provided.

As shown in FIGS. 1 to 4, the case body 2 has a hollow inside and is flat and long so as to extend laterally (in the width direction) and in the full length direction, and is substantially square in plan view or rectangular long in the front and rear direction Is the case of At the bottom of the case body 2, a swing mechanism 10, a drive mechanism 11, and a base plate 5 on which a control unit 12 for controlling these two mechanisms is installed.
On the other hand, an opening 4 opened upward is formed on the upper surface of the case body 2. The opening 4 has a substantially square shape in plan view. The swing mechanism 10 and the drive mechanism 11 are disposed to protrude upward from the opening 4. That is, the case body 2 is lower in height than the swing mechanism 10 and the drive mechanism 11.

In addition, the structure of this case body 2 is not specifically limited, What is necessary is just a structure which can be stably supported on the floor surface F even during operation of the apparatus.
Now, on the front end side of the case body 2, a pair of holding bar support portions 9 for supporting the holding bar 6 in an upright position is provided at a constant interval in the width direction. The gripping bar support 9 is a cylindrical member and is protruded upward. As described above, by providing the holding bar supporting portion 9 on the front end side of the case body 2 and extending forward, the case body 2 is further enhanced in stability.

As shown in FIG. 1 and FIG. 2, the holding rod 6 is formed of a long rod, and the user M on the riding portion 3 can hold the tip of the holding portion 3 on the front side of the riding portion 3 A pair is provided at the position where
That is, a pair of holding bars 6 (sticks) is provided diagonally in front of the riding portion 3 and within the movable range in the horizontal direction of the arm portion of the user M. In the first embodiment, the movable range in the horizontal direction of the arm portion of the user M is a range in which the tip end (upper end) of the gripping rod 6 can easily reach when the user M bends an elbow. And

Preferably, the gripping bar 6 is provided at a position where it can be gripped by the user M of the boarding part 3 with the elbow bent deeply (approximately 60 to 90 °).
Further, as shown in FIG. 3, it is preferable that the deployment position of the gripping rod 6 be provided in a range (two-dot broken line) opened 30-60 ° diagonally outward from the front direction of the riding portion 3 in plan view. . In the first embodiment, it is provided at a position opened approximately 45 degrees to the diagonally outer side from the front direction of the riding portion 3. That is, it is preferable that the pair of gripping bars 6 be at a position where the distance in the width direction corresponds to the shoulder width of the user M.

By arranging the pair of gripping bars 6 as described above, the user M can naturally grasp the gripping bars 6 naturally, and an effective twisting motion for twisting the waist and abdomen of the user M is stabilized. Can be implemented.
The holding rod 6 is made of metal, but may preferably be made of a resin-based material containing a carbon material excellent in flexibility, elasticity, and bending strength. As a result, even if the user M pushes and pulls the gripping rod 6 strongly, the user M will not easily break or bend.

At the tip of the gripping bar 6, a grip 7 shaped so as to be easily gripped by the user M is provided. That is, the grip 7 is formed in a shape in which the tip end is bent backward.
Specifically, as shown in FIG. 4, the grip 7 extends upward from the proximal end, and has a shape that largely curves rearward as going from the longitudinal middle portion to the distal end. That is, the grip 7 is formed such that its tip is directed upward.

As described above, since the tip end of the gripping bar 6 is formed to be bent backward, the user M can easily grip from above. That is, the gripping bar 6 of the first embodiment is configured to be easily held by both the tall user M and the short user M. In other words, if the gripping bar 6 has the shape of the first embodiment, it can be coped with even if the user M has a height difference.
The material of the grip 7 is desirably one having softness or elasticity such as rubber.

At the tip of the holding rod 6 on at least one side (right side in the first embodiment) of the pair, an operation unit 8 for issuing an operation command to the swing mechanism 10 and the drive mechanism 11 is provided.
That is, on the front side of the grip 7, for example, an operation unit 8 is provided which issues a command to start and stop the rocking mechanism 10 and the drive mechanism 11, and to switch the twisting operation.
The switching of the twisting motion may be, for example, switching of the speed of twisting the board, switching of the twisting angle of the board, such as swinging the board to the left and right largely, or shaking little by little.

Since the operation unit 8 is provided on the front side of the grip 7 within the reach of the fingertips, the switching operation of the twisting motion, the swinging mechanism 10, and the like can be performed immediately while the user M is performing a twisting motion of the waist and abdomen. The drive mechanism 11 can be started and stopped.
In the first embodiment, the holding bar 6 is in the fixed state, but may be freely operable in the front, rear, left, right, and diagonal directions. That is, as in an airplane control stick (joystick), the holding bar 6 may be able to be turned in four directions. Such a configuration further approximates the ski operation.

At the rear of the pair of holding rods 6, a boarding portion 3 (a platform) is disposed.
The boarding section 3 has an area where the user M can safely get on even if the user M is performing a twisting motion. The boarding portion 3 is preferably made of, for example, resin, metal or the like, and the shape in plan view may be formed as a rectangular shape or the like long in the front and back direction. In the case of the first embodiment, an elastic material such as urethane is provided on the support member 20, and the riding portion 3 is formed by providing a silicon material so as to cover the elastic material. That is, the riding section 3 has a laminated structure of a silicon material (upper part) and a urethane material (lower part).

It is desirable that the boarding portion 3 is formed on the upper surface thereof in such a form (size, shape, strength, etc.) that the left and right foot portions of the user M can be aligned. The forming material, shape, size, strength, and the like of the riding section 3 are not particularly limited as long as the safety of the user M is ensured.
A placement recess 13 (foot placement portion) is provided on the upper surface of the riding portion 3, in other words, at the position where the foot portion of the user M is placed on the silicon material. The placement recess 13 is a recess slightly wider than the foot, and is provided at a position corresponding to each of the right foot and the left foot.

Further, a non-slip member 14 is provided on the plane of the placement recess 13. About the non-slip member 14 of the first embodiment, a plurality of protrusions are provided.
The non-slip member 14 (convex protrusion) has a cylindrical shape and has a diameter of about 5 mm and a height of about 10 mm. In the case of the first embodiment, the anti-slip member 14 is provided only on the rear half side in the mounting recess 13. That is, the anti-slip member 14 is provided only in the range from the rear end to the approximate center in the placement recess 13, and the front end in the placement recess 13 from the approximate center , The non-slip member 14 is not provided.

There is a reason to adopt the configuration described above.
That is, as detailedly stated in the "Problem to be solved by the invention", when the riding portion 3 is violently swung back and forth and left and right, the surface of the riding portion 3 is made of a silicon material having a non-slip function Therefore, although the foot of the user M does not come off the riding section 3 greatly, the movement of the foot (especially the foot sole) may not follow the violent movement of the riding section 3. If this situation continues, the surface of the platform 3 and the back of the user M's foot will rub against each other, causing heat on the back of the foot, and in the worst case, beans on the back of the foot There is no doubt that such as a scratch may occur.

  In order to prevent that, in the riding section 3, the user is placed between the placement recess 13 (foot placement portion) where the user M places his / her foot and a place other than the placement recess 13 (foot placement portion) The friction state of M against the back of the foot is different. In particular, in the stand-up type exercise apparatus 1 of the present embodiment, a configuration is also adopted in which the friction state of the user M against the back side of the foot differs depending on the place even in the placement recess 13 (foot placement portion).

  Specifically, the anti-slip member 14 is installed in the rear area (portion corresponding to the heel of the foot) in the mounting recess 13, and the front area in the mounting recess 13 (portion corresponding to the toes of the foot) ) And the anti-slip member 14 is not installed, and the placement recess 13 is formed so that the friction state of the user M against the back side of the foot differs in the front-rear direction. When the configuration shown in the first embodiment is adopted, the friction coefficient with respect to the sole differs between the front and rear sides in the mounting recess 13, and the sole effect of the different friction state makes the sole Is strongly restrained (gripped) by the mounting recess 13, and it is possible to prevent, as much as possible, a situation where the surface of the platform 3 and the back of the user M's foot rub against each other.

The applicant has confirmed that when the inside of the placement recess 13 is entirely in the same state (same friction state), the above-described remarkable effects can not be obtained. For example, even if the anti-slip member 14 is installed in the entire area in the mounting recess 13, the back of the user M's foot moves relative to the front surface of the platform 3 to effectively prevent the situation where they rub against each other. It is confirmed that it is impossible to do.
In addition, even if the anti-slip member 14 is installed only in the range on the front side in the placement recess 13 (the part corresponding to the toes of the foot), the front surface of the platform 3 and the back surface of the user M's foot , It has been confirmed that it is not possible to prevent effectively the situation where each other rubs.

As described above, the foot portion is hardly slipped by the placement recess 13 and the anti-slip member 14, and the user M does not fall from the riding portion 3 when performing the twisting motion, and the foot sole is not convenient. It does not occur.
In the case of the first embodiment, in the range on the front side in the mounting recess 13, a plurality of bar-like protrusions 50 extending in the back and forth direction are formed, and the coefficient of friction for the sole (toe) is appropriate. It is assumed.

  In addition, a flexible elastic member 15 is provided on the outer periphery of the riding portion 3 so as to cover it. Examples of the elastic member 15 include a rubber sheet and a cushion sheet material. The upper surface of the riding portion 3 may also be provided to cover the elastic member 15. Thus, by covering the boarding portion 3 with the elastic member 15, it becomes possible to reliably avoid an adverse situation such as pinching of the boarding portion 3 and the floor surface F, and security is enhanced. The elastic member 15 is realized by providing the silicon material constituting the riding portion 3 so as to protrude in a substantially horizontal direction (a projection portion or a ridge portion).

In addition, a lining material 16 is provided between the lower side of the riding section 3 and the opening 4.
Now, as shown in FIG. 2, the riding portion 3 is formed in a shape (V-shaped or U-shaped) jumping up from the center toward both end portions in the left-right direction. That is, the center of the riding section 3 is lower than both end portions in the left-right direction.
When the boarding platform is shaped so as to jump from the center toward the left and right direction ends, the posture of the user M on the boarding platform actually slips at the time of skiing (both knees slightly bent and the waist slightly dropped Since the posture is similar to that of the case (with the lower limbs bent), motion closer to the ski motion can be realized. By realizing this posture, the twisting motion for the user M becomes more effective.

As shown in FIG. 2 and FIG. 4, in the case body 2 and below the boarding part 3, a twisting operation is generated by reciprocating the boarding part 3 back and forth and left and right around the vertical axis. A swing mechanism 10 and a drive mechanism 11 for driving the swing mechanism 10 are provided.
As shown in FIGS. 2 to 4, in the swing mechanism 10, the front end portion and the rear end portion of the swinging mechanism 10 in the left-right direction centering on the center portion (position located at the center in both the left-right direction and the front-rear direction) Operate in reverse phase.

That is, as shown in FIG. 3, when the front end of the riding portion 3 swings to the right, the rear end moves to the left, and when the front end swings to the left, as shown in FIG. This causes “right and left reciprocating swing” such that the rear end moves to the right.
Further, at the same time as these “right and left reciprocating swings”, the swing mechanism 10 operates with the front end portion and the rear end portion in opposite phases in the front-rear direction centering on the center portion of the riding portion 3.

That is, as shown in FIG. 2 and FIG. 4, when the front end of the riding section 3 is swung to the right as shown in FIGS. 2 and 4, the upper surface of the riding section 3 is lowered to the left. Produces a “twist movement (compound twist movement) in which front and rear rocking and left and right rocking are combined” in such a manner that the upper surface of the riding portion 3 is lowered to the right when it is swung to the left.
In addition, the operation of the above-mentioned "compound twist movement" is an example, and is not limited to this operation. For example, when the front end portion is swung to the right, the upper surface of the riding section 3 may be lowered to the right.

By this “composite twisting motion”, it is possible to give a suitable balance exercise to the user M who got on the boarding part 3 in a standing position, and to give a twisting motion to the waist and abdomen of the user M It becomes.
Now, as can be seen also with reference to FIGS. 2 to 6, in the first embodiment, the height of the support member 20 (details will be described later) for supporting the riding portion 3 from below is low. The lower side of the opening 4 of the case body 2 and the boarding portion 3 are very close to each other even in the stopped state.

Under such a condition, when the “composite twisting motion” of the riding portion 3 by the swing mechanism 10 is performed, the space between the opening 4 and the lower side of the riding portion 3 is further narrowed.
Specifically, as shown in FIG. 5 to FIG. 6, there is a space which can be formed under the mounting portion 21 (details will be described later) constituting the support member 20 and above the reduction gear 34 constituting the drive mechanism 11. When the boarding section 3 is performing “composite twisting motion”, the space may be narrower than the thickness of the hands and feet.

If the hands and toes accidentally enter such a narrow space, there is a possibility that they may be caught by the swinging riding portion 3.
A safety member 17 is provided between the lower side of the boarding portion 3 and the upper side (opening 4) of the case body 2 in order to prevent entry into the narrow space at the hands and feet and pinching by the swinging boarding portion 3 or the like. Is provided.

As shown in FIGS. 5 to 6, in the first embodiment, the safety member 17 (safety member 17 (a safety member 17 (a safety member 17 (a safety member 17 (a safety member 17 (a safety member It is supposed to be provided as a cover.
In other words, the safety member 17 is formed of a wedge-shaped plate material protruding obliquely downward and outward from the right side of the mounting portion 21 of the support member 20. The safety member 17 has a proximal end attached to the lower portion of the mounting portion 21 and a distal end inserted into the case 2 from the opening 4.

The length of the safety member 17 in the vertical direction is longer than the height of the narrow space, and the tip is not in contact with the bottom portion (base plate 5) of the case body 2 when the riding portion 3 is swinging. There is. The length of the safety member 17 in the front-rear direction is longer than the length of the reduction gear 34 in the front-rear direction.
Most of the space formed on the side of the drive mechanism 11 is narrow, so it is preferable to provide the safety member 17 so as to cover at least the drive mechanism 11. That is, the safety member 17 may be provided to cover a narrow space which can be formed at least below the opening 4 of the case body 2 and the lower side of the riding portion 3.

As shown in FIG. 4, when the stand-up type exercise apparatus 1 is viewed from the right side, the narrow space between the lower side of the riding section 3 and the opening 4 is blocked from the outside by the safety member 17. It has become. That is, from the right side, the safety member 17 can not see the drive mechanism 11 (the reduction gear 34).
Note that, for the purpose of improving the safety during the “composite twisting motion”, for example, the safety member 17 orbits the outer circumference of the rocking mechanism 10 and the drive mechanism 11, that is, a frame member surrounding the opening 4 May be provided.

For example, as shown in FIGS. 2 and 4, an annular sponge body 51 (elastic body) surrounding the entire gap between the opening 4 and the riding portion 3 (that is, a gap opened in the vertical direction and opening in four directions) The upper and lower gaps may be closed with this sponge body.
Specifically, a lining material 16 (cloth body) surrounding the upper and lower gaps so as to be able to be closed is disposed, and a sponge body 51 having a thickness of several centimeters is disposed on the inner side of the lining material 16 Do. The lining material 16 may be a two-ply structure, and the sponge body 51 may be disposed therein.

  The upper edge of the lining material 16 in such a state is attached to the lower end of the mounting portion 3, and the lower edge of the lining material 16 is attached to the periphery of the opening 4 opened in the case body 2. At this time, by generating tension in the vertical direction in the lining material 16, the sponge body 51 is pulled up and down, and the strength is increased. The user's finger or the like can be reliably prevented from entering the drive mechanism 11.

Thus, by providing the safety member 17 which covers the narrow space which can be made between at least the lower side of the boarding portion 3 and the upper side (opening 4) of the case body 2 during the “composite twisting movement”, It is possible to prevent entry and pinching of the feet.
Back, the swing mechanism 10 also has a role of connecting the case body 2 and the riding portion 3. The lower side of the swing mechanism 10 is connected to the case body 2, and the upper side of the swing mechanism 10 is boarded. It is connected to the lower surface of the part 3.

  As shown in FIGS. 5 to 6, the swing mechanism 10 supports the rotating shaft 18 rotationally driven by the drive mechanism 11 and the riding portion 3 from below, and connects the riding portion 3 and the case body 2. Supporting member 20, converting a rotational driving force from the rotating shaft 18 into a reciprocating oscillation and transmitting the same to the supporting member 20, and restricting the rotation of the supporting member 20 along with the rotating shaft 18 And a control unit 29.

The rotating shaft 18 is mounted below the boarding portion 3 so that the axial center is in the left-right direction. The rotary shaft 18 is inserted into the reduction gear 34 of the drive mechanism 11 at the right end side, and is rotatably supported via a bearing 37 (bearing). Further, the left end side of the rotating shaft 18 is rotatably supported by the rotating shaft support 19 via a bearing 37.
The support member 20 supports the user M who is riding in the standing position on the riding portion 3 from below. The support member 20 has a mounting portion 21 to which the mounting portion 3 is attached on the upper surface, and a support portion 22 that supports the mounting portion 21 from below.

  The mounting portion 21 is a flat plate facing in the horizontal direction, and has a width such that a predetermined portion of the pair of mounting concave portions 13 provided in the riding portion 3 can be accommodated. That is, the placement unit 21 has an area in which the foot of the user M who is riding in the standing position can be placed via the boarding unit 3. In other words, it can be said that the user M in the standing position is on the placement unit 21 via the boarding unit 3.

The thickness of the mounting portion 21 is set to a thickness that can withstand the load by the user M, since the user M can stand in the standing position.
As shown in FIG. 6, the support portion 22 has an expanded shape that spreads from the lower end toward the upper end in a front view. That is, the support portion 22 is an inverted triangle-like member having a wide width at the upper end and a thickness in the left-right direction, which gradually widens from the lower end to the upper end. The lower end of the support portion 22 also has a constant thickness.

The support 22 preferably has a width in the left-right direction on the upper end side at least twice as large as a width on the lower end side in a front view. In other words, it is preferable that the width in the left-right direction of the upper end of the support portion 22 be at least 1/2 or more of the width in the left-right direction of the mounting portion 21.
In the first embodiment, the width of the upper end side of the support portion 22 is about four times as wide as the width of the lower end side in a front view. As compared with the width in the left-right direction of the placement unit 21, the width on the upper end side of the support unit 22 is approximately 3⁄5 of the width of the placement unit 21.

  Furthermore, as shown in FIG. 5, the support portion 22 is formed such that the expanded shape is continuously formed from the front side to the rear side. That is, the upper surface of the support portion 22 is continuously wide in a direction from the front end to the rear end. Moreover, the support part 22 is made into the expanded shape which spreads toward a upper end from a lower end in a side view. The mounting portion 21 and the support portion 22 may be integrally formed with respect to the support member 20.

  In the support member 20, the support portion 22 gradually widens from the lower end to the upper end, and the upper surface is as wide as about 1/2 or more of the area of the mounting portion 21 (circled by a dashed line in FIG. And the main body of the member has high strength. That is, the support member 20 can support the user M who got on the boarding part 3 in a standing position from below while securely avoiding a failure such as breakage.

  Furthermore, the support portion 22 is a member that gradually widens from the lower end side toward the upper end side and is a thick member in both the front-rear direction and the left-right direction in which the wide state continues from the front end to the rear end. The vertical height of the support member 20 can be reduced. That is, the boarding position of the user M (the deployed height of the boarding unit 3) can be made much lower than in the conventional case, and the ease with which the user M rides on the boarding unit 3 is improved.

As shown in FIG. 6, on the lower end (proximal end) side of the support member 20, a conversion unit 23 for converting the rotational drive force from the rotary shaft 18 into reciprocating oscillation is disposed.
The conversion unit 23 converts the rotational driving force from the rotation shaft 18 into the above-described “composite twisting motion” and transmits the converted driving force to the riding unit 3 that operates together with the support member 20. The conversion portion 23 is provided at the base end of the rotation boss portion 24 fixed to the rotation axis 18 so as to integrally rotate with the rotation axis 18 and at the base end of the support member 20. It has an annular fitting portion 27 to be inserted, and a restricting portion 29 that restricts the support member 20 from rotating with the rotating shaft 18.

  The rotary boss portion 24 has the rotary shaft 18 fitted thereon, and a cam surface 25 shaped like a slant with respect to the rotary shaft 18 is provided on the outer peripheral surface. The hole 26 of the rotation boss 24 through which the rotation shaft 18 passes is formed eccentrically with respect to the center of the outer circumferential circle of the rotation boss 24. That is, the rotation boss portion 24 performs both inclined rotation and eccentric rotation with respect to the axial center of the rotation shaft 18. The inclination of the rotation boss portion 24 (cam surface 25) is an inclination that enables the support member 20 to realize the "composite twisting motion".

The annular fitting portion 27 is formed at the base end of the support member 20 and externally fits the rotary boss portion 24 via the bearing 28 (bearing) in a relatively rotatable state. The bearing member 20 reciprocates and oscillates due to the inclined rotation and the eccentric rotation of the rotating boss portion 24.
The restricting portion 29 restricts the annular fitting portion 27 from rotating with respect to the rotation boss portion 24. The restricting portion 29 is disposed below the rotating shaft 18.

The restricting portion 29 is provided with a restricting pin 30 provided on the base end side of the support member 20, and a restricting groove 31 provided at a position facing the restricting pin 30 and in which the restricting pin 30 slidably fits. Have.
In the first embodiment, the restriction pin 30 is a cylindrical protrusion, and protrudes downward from the base end (below the annular fitting portion 27) side of the support member 20. Further, the restriction groove 31 is provided on the base plate 5 provided below the restriction pin 30 and provided at the bottom of the case body 2. The restriction groove 31 is a groove that is long in the left-right direction, and the restriction pin 30 is slidably inserted in the left-right direction.

A drive mechanism 11 for rotating the rotating shaft 18 is disposed on the base plate 5 at the right end side of the rotating shaft 18.
The drive mechanism 11 has a drive motor 32 that outputs a rotational drive force, and a reduction gear 34 that reduces the speed to a predetermined speed. The reduction gear 34 has a gear mechanism 35 for reducing the speed to a predetermined speed, and a gear case 36 for storing the gear mechanism 35. The drive motor 32 is provided so that the output shaft 33 is lower than the rotation shaft 18 and directed to the front. The output shaft 33 of the drive motor 32 is inserted into the reduction gear 34 and connected to the rotating shaft 18 via the gear mechanism 35.

A power transmission mechanism 38 is provided between the conversion unit 23 and the rotation shaft 18 to reliably rotate the rotation shaft 18 and the conversion unit 23. That is, the power transmission mechanism 38 prevents a slip from occurring on the rotating shaft 18 on which the rotating boss portion 24 is rotating due to a large load from the user M when performing the “composite twisting motion”. It is a mechanism for
In the first embodiment, the power transmission mechanism 38 is a spline formed of an external gear 39 formed on the outer peripheral surface of the rotary shaft 18 and an internal gear 40 formed in the rotary boss portion 24. . The internal gear 40 and the external gear 39 mesh with each other, so that no slip of the rotary boss portion 24 occurs on the rotary shaft 18. In the first embodiment, the external gear 39 is formed on the outer peripheral surface of the central portion in the longitudinal direction of the rotating shaft 18, and the internal gear 40 is a hole through which the rotating shaft 18 penetrates. It is formed.

Since the rotary boss portion 24 does not slip by the power transmission mechanism 38 even when a large load is applied from the user M when performing the “composite twisting motion”, conversion of the reciprocating rocking motion in the converting portion 23 is performed It can be done surely. That is, it becomes possible to transmit "the combined twisting movement" to the boarding part 3 with certainty, and it becomes possible to impart a twist effect to the waist and abdomen of the user M.
[Operation mode]
Next, the operation mode of the riding type exercise apparatus 1 of the present invention will be described.

The user M rides in a posture of standing on the boarding portion 3 in a power-off state.
Hold the grip 7 provided on the tip of each holding rod 6 with both hands, and use the operation unit 8 provided on the tip of the holding rod 6 on one side (right side in this embodiment) to turn on the start switch Make it
Then, the drive motor 32 of the drive mechanism 11 outputs a rotational drive force from the output shaft 33. The rotational driving force is decelerated to a predetermined speed by the reducer 34 and transmitted to the rotating shaft 18 through the gear mechanism 35. Along with that, the rotating bosses 24 attached to the rotating shaft 18 rotate together. In addition, since the rotating shaft 18 and the rotating boss portion 24 are meshed by the power transmission mechanism 38, they rotate together reliably.

The bearing member 20 externally fitted to the rotary boss portion 24 via the annular fitting portion 27 tends to rotate in the same direction as the rotational direction of the rotary shaft 18. At this time, since the restriction pin 30 provided below the annular fitting portion 27 slides in the restriction groove 31, the co-rotation of the rotation boss 24 and the support member 20 is restricted.
The rotating boss portion 24 is eccentric to the rotating shaft 18 and the cam surface 25 is inclined with respect to the rotating shaft 18. Also, the restriction pin 30 slides along the long restriction groove 31 in the left-right direction. Therefore, the support member 20 reciprocates in a combined swing motion in the lateral and longitudinal directions with the rotation of the rotary shaft 18.

  That is, when the front end portion of the riding section 3 is swung to the right and its upper surface is lowered to the left, the rear end is shaken to the left and its upper surface is increased to the right. On the other hand, when the front end of the riding portion 3 is swung to the left and its upper surface is lowered to the right, the rear end is shaken to the right and its upper surface is increased to the left. The swing mechanism 10 has a front end portion and an end rear portion in opposite phase with respect to the riding portion 3 connected via the support member 20 with respect to the center of the riding portion 3 in plan view as described above. It will cause "composite twist movement".

Therefore, the user M who stands on the riding section 3 and holds the tips (grips 7) of the left and right sticks is given a motion to twist the waist and abdomen, and at the same time the balance is broken. Will be given a “composite twisting motion” that In other words, the user M can experience an exercise similar to ski motion (in particular, mogul motion).
In other words, the user M is given a stable posture in which the upper body does not move as much as possible, and a posture in which both knees are slightly bent (a posture in which the waist is lowered and bent). Focus on the “complex twisting movement”.

This “composite twisting motion” can strengthen the muscles of each part of the user M (especially the trunk) and the sense of balance. In addition, health promotion such as diet can be planned by "composite twist exercise" which performs various swings.
Moreover, since the above-mentioned "compound twist movement" is carried out where it rides and uses while standing on the boarding part 3, it is possible to exercise without getting tired even by daily repeated use, and further novelty You can taste the fun.

  In addition, even if the strength of this composite twisting motion is strong and the riding portion 3 swings violently, as described above, the anti-slip member 14 is disposed in the rear range (portion corresponding to the heel of the foot) in the mounting recess 13 Since the anti-slip member 14 is not installed in the range in the front part (portion corresponding to the toes of the foot) in the mounting recess 13, the friction state with respect to the sole is different. By the action, the sole of the foot is strongly gripped by the mounting recess 13.

Therefore, relative movement between the placement recess 13 and the back of the foot is suppressed, and no inconvenience occurs to the sole of the user M.
