Description

Balance exercise device

The present invention relates to a balance exercise apparatus in which a user on a boarding platform performs an exercise naturally in order to maintain its own posture just as if it were on a balance ball.

BACKGROUND ART Conventionally, exercise devices called balance balls (body balls) are distributed in the market. The balance ball is for the user to sit on the balance ball or to be in close contact with the body to perform a training of sense of balance. The size of the balance ball is about 50 cm to 100 cm, and since the shape is a ball shape, it easily rolls on a floor surface or the like. Also, although the balance ball is inflated with air or the like inserted inside, it deforms so as to collapse when supporting the weight of the user. That is, when the user is placed on the balance ball, the balance ball is very unstable due to deformation or rolling, and the user can not get on the unstable balance ball without twisting or tilting his body. In other words, when placed on the balance ball, the user unintentionally exercises naturally in an attempt to maintain the posture, and this exercise is a useful exercise for the body.

The balance ball is effective not only in exercise but also in improving the sense of balance, correcting the posture, improving the muscle strength and the like.
However, it is necessary to get used to using a balance ball, and considerable training is required to use the balance ball for exercising. For example, even if a beginner tries to exercise "sit on a balance ball" with a large exercise effect, performing such exercise requires a high sense of balance, and such an exercise for users who are not used to it It is not easy to do.

In addition, even if the user is accustomed to the handling of the balance ball to some extent, the ball may move in an unexpected direction during use, which may cause a dangerous situation such as the user falling onto the floor.
Therefore, in order to avoid the above-mentioned dangerous situation, Patent Document 1 relates to a “balance ball auxiliary frame” that can prevent the balance ball from rolling more than expected by surrounding the frame member around the balance ball. Disclose technology.

However, when exercise is performed using a balance ball auxiliary frame as disclosed in Patent Document 1, rolling of the balance ball is surely restricted by the auxiliary frame, so the user needs to make much balance on the balance ball. It will be gone. In other words, in the exercise machine of Patent Document 1, the user does not try to maintain the posture on the unstable balance ball, and it seems that the original exercise effect can not be extracted, and sufficient exercise can be performed. It is doubtful.

Therefore, in order to obtain the movement effect by the balance ball while eliminating the risk that the balance ball falls in an unexpected direction and the user falls, an exercise machine inspired by the movement of the balance ball has also been developed. .
For example, Patent Document 2 discloses an exercise device in which a balance ball is attached below a disc made of hard plastic or aluminum that can be used by a user.

JP 2008-264096 A JP 2000-60994 A

However, in the exercise machine disclosed in Patent Document 2, the board on which the user rides is substantially flat, and the user can sit in a very stable posture on the board. Therefore, it is difficult to realize the "unstable feeling of posture" that the original balance ball has. Naturally, in the exercise machine of Patent Document 2 having such a stable platform, the user does not have to try to hold or restore his own posture, and "balance improvement" or "muscle strength" by the balance ball It seems difficult to express effects such as “up effect”.

Then, an object of this invention is to provide the balance exercise | movement apparatus which can perform an effective exercise | movement, although a user can use stably, without falling in view of the said problem.

In order to achieve the above object, the following technical measures are taken in the present invention.
The balance exercise apparatus according to the present invention includes a riding portion on which a user can ride in various postures, and a swing mechanism disposed below the riding portion and swinging the riding portion back and forth or sideways. And a driving mechanism for driving the rocking mechanism, and a base portion on which the rocking mechanism and the driving mechanism are provided and which can be mounted on a floor surface, wherein the riding portion is upward Have a convex shape.

Hereinafter, an embodiment of a balance exercise device 1 according to the present invention will be described with reference to the drawings.
In addition, the direction for description is suitably illustrated in the drawing. In the following description, details of the balance exercise device 1 will be described using the directions in the drawing.
First Embodiment
The balance exercise device 1 includes a riding portion 2 on which the user M can ride in various postures, and a swing mechanism 3 disposed below the riding portion 2 and swinging the riding portion 2 back and forth and right and left The drive mechanism 4 for driving the swing mechanism 3, and the base portion 5 which can be mounted on the floor surface F while incorporating the swing mechanism 3 and the drive mechanism 4. The balance exercise device 1 can cause the user M to perform an exercise similar to an exercise device conventionally called balance ball (body ball) (hereinafter, this exercise may be referred to as balance exercise).

That is, in the balance exercise device 1 of the present embodiment, the user M on the balance ball twists or stretches the body unintentionally (naturally) in an attempt to maintain its posture on the unstable balance ball. It enables the user M to perform an exercise similar to a balancing exercise. Specifically, the balance exercise apparatus 1 of the present embodiment mechanically swings the boarding portion 2 on which the user M rides and breaks the posture of the user M in the same manner as when the user M is on the balance ball. Then, it is a device for causing the user M to perform a balance exercise.

In the following, first, the riding portion 2, the swing mechanism 3, the drive mechanism 4, and the base portion 5 which constitute the balance exercise device 1 of the present embodiment will be described.
As shown in FIGS. 1 and 3, the base portion 5 is a flat plate having a substantially circular shape in a plan view, and is smaller than the diameter of the riding portion 2 (details will be described later) having a circular shape in a plan view. The bottom surface (lower surface) of the base portion 5 is formed in a flat surface shape, and can be stably mounted on the floor surface F or the like. The swing mechanism 3, the drive mechanism 4, and a control unit (not shown) for controlling these two mechanisms are installed on the base 5.

If the bottom surface of the base portion 5 described above is formed into a flat surface, the base portion 5 can be stably installed on the floor surface F or the like, and the balance exercise device 1 is largely horizontal as in the rolling of a balance ball. I will never move to As a result, the problem that the balance ball falls in an unexpected direction and the user falls does not occur.
The structure of the base portion 5 is not particularly limited as long as it can be stably supported on the floor F even during operation of the apparatus. Moreover, you may have the case body arrange | positioned so that the base part 5 may be enclosed.

Above the swinging mechanism 3 and the drive mechanism 4 described above, a boarding portion 2 is provided, on which the user M can ride in various postures.
The riding section 2 divides the sphere into two along the horizontal direction at a position about 1/5 from the upper end of the sphere, and it is shaped such that only the lower part is removed leaving the upper part among the divided ones. It is In other words, the boarding part 2 is shaped like a dome-opened umbrella or a mushroom bulk part.

Specifically, the boarding portion 2 is formed in a circular shape having a diameter larger than the diameter of the base portion 5 in plan view, and the center position of the base portion 5 and the center position of the boarding portion 2 substantially coincide with each other And the base portion 5 is concealed so as not to be visible when viewed from above.
The side view of the boarding portion 2 is convex upward and has a semicircular dome shape. In the case of the present embodiment, the riding portion 2 is formed to have a curvature such that the central portion is higher by about 50 mm to 150 mm than the peripheral portion, and the user places the curvature in the central portion provided at this high position. It is possible to get on board while keeping balance. If the boarding portion 2 is formed in such a convex shape, it becomes difficult for the user M to sit on the boarding portion 2 stably, and the user M can perform balance exercise.

In addition, although the boarding part 2 to show in figure is circular shaped, it is not limited to this, An elliptical shape may be sufficient. That is, the riding section 2 may have different lengths in the front-rear direction and in the left-right direction. Moreover, the boarding portion 2 may be non-circular in plan view, for example, a quadrangle or a hexagon. The riding portion 2 is not limited to a semicircular shape in a side view, and may be, for example, a triangular shape (angular shape) with rounded corners. That is, it may be pyramidal in perspective.

Specifically, the riding portion 2 has a dome-shaped core body 6 formed of hard plastic or the like inside, and an intermediate material 7 formed of urethane or the like is disposed on the entire top surface of the core portion 6. A covering material 8 formed of silicone rubber or the like is disposed further outside the intermediate material 7.
That is, the above-described intermediate material 7 covers the core 6 entirely from the upper side, and the covering material 8 covers the outside of the filling material 7. In other words, the covering material 8 (upper part) and the intermediate material 7 (lower part) It has a double-layered laminated structure. Further, the intermediate material 7 described above is formed on the core body 6 in a thickness of about 50 mm to 100 mm so as to follow the dome-like outer shape of the core body 6 described above. As described above, when the boarding portion 2 has a laminated structure or the intermediate member 7 is thickened, the surface of the boarding portion 2 has elasticity to a certain degree, and the user M can be given a good sitting comfort.

Furthermore, a plurality of anti-slip ribs are formed on the upper surface of the boarding portion 2 to prevent the user from sliding off the boarding portion 2. Each of these non-slip ribs is formed so as to draw an annular ring centering on the central portion of the boarding portion 2, and a plurality of anti-slip ribs having different diameters are directed from the central portion to the peripheral portion of the boarding portion 2 It is possible to prevent the user M seated at the central portion of the riding portion 2 from sliding down to the peripheral portion.

Furthermore, even if the swinging movement with respect to the user M is carried out, the boarding unit 2 has a width that allows the user to get on safely (about 500 mm to 700 mm in diameter in the case of this embodiment, as viewed from above) The user M is stable on the boarding portion 2 because a certain degree of friction is realized between the covering material 8 and the user M. It is possible to go on board.

In addition, the boarding part 2 will be rock | fluctuated so that the track | orbit of a figure of 8 may be drawn, for example in front and rear, right and left by the rocking | fluctuation mechanism 3 mentioned later. Therefore, since the rocking trajectory in the front and back direction and the rocking trajectory in the left and right direction are different from each other, a sign indicating the front and back direction and the left and right direction is given to the riding portion 2 It is preferable that the mark which shows what should be carried out is stamped. As such a mark (mark), for example, a mark may be put on the front side of the boarding portion 2, or a line indicating the left-right direction or a line indicating the front-rear direction may be engraved on the surface of the boarding portion 2.

In addition, LED lighting or the like that emits various lights may be embedded in the inside of the riding portion 2 (below the covering material 8), or various patterns may be formed on the surface of the riding portion 2 (surface of the covering material 8). By setting it up, the exercise device 1 looks good. Moreover, LED illumination and various patterns etc. can also be used as an engraving mentioned above.
Furthermore, a flexible elastic member may be provided around the outer periphery of the riding portion 2 so as to cover the riding portion 2 from the periphery. Thus, by covering the boarding portion 2 with the elastic member, it is possible to reliably avoid an adverse situation such as pinching of the boarding portion 2 and the floor surface F, and the safety is enhanced. As the elastic member, it can be considered that the covering material 8 constituting the riding portion 2 is provided so as to protrude in a substantially horizontal direction (a projecting portion, a collar portion, or the like).

Further, a lining material (not shown) is provided between the lower side of the riding portion 2 and the base portion 5 (or the opening 4 of the case body). By this lining material, it is possible to make the swing mechanism 3 and the drive mechanism 4 invisible from the outside.
Furthermore, an annular sponge body (not shown) is formed which encloses the entire surface of the gap between the lower side of the mounting portion 2 and the base portion 5 (that is, the gap opened in the vertical direction and opening in four directions). The upper and lower gaps may be closed with this sponge body.

Specifically, an inner lining material is provided so as to close the upper and lower gaps, and a sponge body having a thickness of several centimeters is disposed on the inner side of the inner lining material. The lining material may be a two-ply structure, and the sponge body may be disposed therein.
The upper edge of the lining material in such a state is attached to the lower end of the riding portion 2, and the lower edge of the lining material is attached to the base portion 5 (or the periphery of the opening opened in the case body) Make it At this time, by generating tension in the vertical direction in the lining material, the sponge body is pulled up and down, and the strength is increased. Therefore, the swing mechanism 3 and the drive mechanism in the opening from the outside Thus, it is possible to reliably prevent the finger of the user M and the like from entering 4).

Next, as shown in FIG. 4 and FIG. 5, the boarding portion 2 is reciprocated forward and backward and to the left and right on the base portion 5 and below the boarding portion 2, and the boarding portion is turned around the axis facing up and down. A swing mechanism 3 for generating a twisting motion to twist 2 and a drive mechanism 4 for driving the swing mechanism 3 are provided.
The rocking mechanism 3 has a rotary shaft 10 rotationally driven by the drive mechanism 4, a support member 11 supporting (supporting) the mounting portion 2 from below, and a reciprocating rocking motion of the rotary shaft 10 along the left-right direction. It has a conversion part 12 which converts it into a dynamic movement (translational movement) and transmits it to the support member 11, and a control part 13 which restricts the support member 11 from rotating with the rotating shaft 10.

The rotating shaft 10 is mounted on the base portion 5 below the boarding portion 2 so that the axial center is in the left-right direction. The rotary shaft 10 is rotatably supported via a bearing 14 about an axis directed in the left-right direction. Further, the right end side of the rotating shaft 10 is inserted into the reduction gear 26 of the drive mechanism 4, and the left end side of the rotating shaft 10 is erected upward from the upper surface of the rotating shaft support 17 (the upper surface of the base 5 via the bearing 14). It is rotatably supported by a member that extends to

The support member 11 supports the riding portion 2 from below. The support member 11 has a mounting portion 15 to which the mounting portion 2 is attached on the upper surface, and a support portion 16 supporting the mounting portion 15 from below.
The placement unit 15 is a plate-like member disposed along the horizontal direction, and has a thickness that can withstand a load (weight) by the user M. The support portion 16 has an expanded shape that spreads from the lower end toward the upper end in a front view. That is, the support portion 16 is a member having an inverted triangle shape (funnel shape) in which the cross section having a large width in the lateral direction and a width in the lateral direction becomes wider gradually from the lower end side toward the upper end side. The lower end of the support portion 16 also has a certain thickness. In addition, about this support member 11, it is good for the mounting part 15 and the support part 16 to be integrally formed.

Thus, since the mounting portion 15 and the support portion 16 are integrally formed, the boarding portion 2 can be disposed at a lower position than a conventional exercise machine using a spherical balance ball, The height from the base portion 5 (in other words, the floor surface F) to the top of the riding portion 2 can be made much lower than that of a conventional balance ball. Therefore, the user M can exercise with confidence without feeling the risk of falling on the floor surface F.

As shown in FIG. 5, at the lower end (base end) side of the support member 11, a converter 12 (converter 12 provided in the swing mechanism 3) converts the rotational drive force from the rotary shaft 10 into reciprocating oscillation. ) Is deployed.
The conversion unit 12 converts the rotational driving force from the rotation shaft 10 into the swinging motion described above and transmits it to the riding unit 2 that operates together with the support member 11. The conversion portion 12 is provided on the rotation boss portion 20 fixed to the rotation shaft 10 so as to integrally rotate with the rotation shaft 10 and at the base end of the support member 11 and fitted on the outer peripheral edge of the rotation boss portion 20 It has an annular fitting portion 21 to be inserted, and a restricting portion 13 which restricts the support member 11 from rotating with the rotating shaft 10.

The rotation boss portion 20 has the rotation shaft 10 fitted on the outside, and a cam surface in the shape of a slant with respect to the rotation shaft 10 is provided on the outer peripheral surface. The hole of the rotation boss 20 through which the rotation shaft 10 passes is formed eccentrically with respect to the center of the outer circumference circle of the rotation boss 20. That is, the rotating boss portion 20 performs both tilt and rotation with respect to the axial center of the rotating shaft 10. In addition, about the inclination of the rotation boss | hub part 20 (cam surface), it is set as the inclination which the support member 11 can implement | achieve rocking movement.

The annular fitting portion 21 is formed at the base end of the support member 11 and externally fits the rotary boss portion 20 via the bearing 22 in a relatively rotatable state. The bearing member 11 reciprocates and swings due to the inclined rotation and the eccentric rotation of the rotating boss portion 20.
The restricting portion 13 restricts the annular fitting portion 21 to rotate with respect to the rotation boss portion 20. The restricting portion 13 is disposed below the rotating shaft 10.

The restricting portion 13 is provided with a restricting pin 23 provided on the base end side of the support member 11, and a restricting groove 24 provided at a position facing the restricting pin 23 and in which the restricting pin 23 slidably fits. Have.
In the present embodiment, the restriction pin 23 is a cylindrical protrusion, and protrudes downward from the base end (below the annular fitting portion 21) side of the support member 11. Further, the restriction groove 24 is provided below the restriction pin 23 and in the base portion 5. The restriction groove 24 is a groove that is long in the left-right direction, and the restriction pin 23 is inserted slidably in the left-right direction.

A drive mechanism 4 for rotating the rotation shaft 10 is disposed on the base 5 at the right end side of the rotation shaft 10.
The drive mechanism 4 has a drive motor 25 that outputs a rotational drive force, and a reduction gear 26 that reduces the speed to a predetermined speed. The reduction gear 26 has a gear mechanism 28 for reducing the speed to a predetermined speed, and a gear case 29 for storing the gear mechanism 28. The drive motor 25 is provided so that the output shaft is below the rotating shaft 10 and faces forward. The output shaft of the drive motor 25 is inserted into the reduction gear 26 and connected to the rotating shaft 10 through the gear mechanism 28.

A power transmission mechanism 27 is provided between the conversion unit 12 and the rotation shaft 10 to reliably rotate the rotation shaft 10 and the conversion unit 12. That is, when the power transmission mechanism 27 is performing the swinging motion, a large load from the user M prevents the slip from occurring on the rotating shaft 10 on which the rotating boss portion 20 is rotating. It is a mechanism.
In the present embodiment, the power transmission mechanism 27 is a spline formed on the outer peripheral surface of the rotating shaft 10. The spline does not cause the slip of the rotating boss 20 on the rotating shaft 10. In the present embodiment, the spline is formed on the right side of the rotation boss 20.
[Operation mode]
The operation mode of the balance exercise device 1 having the above-described configuration will be described.

The user M rides on the riding section 2 in various postures (the posture will be described later) in a power-off state. Thereafter, the start switch 30 provided on the front of the riding section 2 is turned on.
Then, the drive motor 25 of the drive mechanism 4 outputs a rotational drive force from the output shaft. The rotational driving force is decelerated to a predetermined speed by the reduction gear 26 and transmitted to the rotating shaft 10 via the gear mechanism 28. Along with this, the rotating boss 20 attached to the rotating shaft 10 rotates with the rotating shaft 10. In addition, since the rotating shaft 10 and the rotating boss portion 20 are meshed with each other by the power transmission mechanism 27, they rotate together securely.

The bearing member 11 externally fitted to the rotary boss 20 via the annular fitting portion 21 tries to rotate in the same direction as the rotational direction of the rotary shaft 10. At this time, since the restriction pin 23 provided below the annular fitting portion 21 slides in the restriction groove 24, the co-rotation of the rotation boss 20 and the support member 11 is restricted.
The cam surface formed on the outer peripheral surface of the rotating boss portion 20 is inclined with respect to the rotating shaft 10. Further, the restriction pin 23 slides along the long restriction groove 24 in the left-right direction. Therefore, with the rotation of the rotary shaft 10, the support member 11 reciprocates in the lateral and longitudinal directions.

That is, when the front end of the riding section 2 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 section 2 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 3 has an opposite phase with respect to the riding portion 2 connected via the support member 11 with the front end portion and the end rear portion centered on the center of the riding portion 2 in plan view as described above A rocking movement, in other words, a complex twisting movement (a complex eight-figure movement) is produced.

Various methods can be considered as how to ride the boarding part 2 which performs such a movement.
For example, as shown in FIG. 6, it is possible to ride in a crouch-like shape, that is, in a sitting posture. As shown in FIG. 7, it is possible to place the buttocks on the riding section 2 and ride with the legs floating in the air. By performing rocking motion while maintaining this physical condition, the sense of balance will be significantly improved and the muscles of the whole body will be trained. As shown in FIG. 8, it is also possible to ride in the standing posture.

Even in any posture, the riding section 2 is dome-shaped and easily loses balance, and the riding section 2 performs rocking motion on it, so the user M takes muscle of each part of the body. As well as being able to forge, it becomes possible to significantly improve the sense of balance.
In addition, as shown in FIG. 9, it is also possible to roll on the back in a posture of lying on top and place the back portion on the riding portion 2. In this state, it is possible to realize muscle exercise or the like centering on the back portion of the user M by rocking the boarding portion 2.

In addition, as described above, the height from the base portion 5 (in other words, the floor surface F) to the top of the riding portion 2 is very low compared to the conventional balance ball, so the user With a sense of security, M can board the boarding part 2 in various postures.
As described above, by using the balance exercise device 1 of the present invention, the user M can be used safely without imposing a dangerous feeling and the user can overcome the "unstableness" due to the original balance ball. It becomes possible to make the body of the user M manifest "function improvement of the user M's sense of balance, muscle strength-up action" and the like.
Second Embodiment
Next, a second embodiment of the balance exercise device according to the present invention will be described.

The balance exercise apparatus 1 according to the second embodiment includes a riding portion 2 having a convex shape, and a swing mechanism 3 disposed below the riding portion 2 and swinging the riding portion 2 back and forth or laterally. A driving mechanism 4 for driving the rocking mechanism 3 and a base portion 5 on which the rocking mechanism 3 and the driving mechanism 4 are disposed and which can be mounted on a floor surface; However, the point which has a convex shape toward the downward direction differs greatly from the balance exercise device 1 of the first embodiment.

In the base portion 5, the lower portion of the boarding portion 2 bulges downward from the peripheral portion in a side view, and preferably, the base portion 5 bulges downward by injecting air into the base portion 5. The output degree is variable.
More specifically, as shown in FIG. 10 and FIG. 11, the base portion 5 divides the sphere into two along the horizontal direction at a position about 1/5 from the lower end of the sphere, and the lower part of the division It has a shape as if only the upper part was removed leaving. In other words, the base portion 5 has a shape in which the dome-like opened umbrella is turned upside down, or the mushroom bulk portion is turned upside down.

The base portion 5 has a circular shape with a diameter smaller than the diameter of the riding portion 2 in plan view, and the center position of the base portion 5 and the center position of the riding portion 2 substantially coincide with each other. ing.
The side view of the base portion 5 is convex downward and has a semicircular dome shape. The swing mechanism 3 and the drive mechanism 4 are disposed substantially in the center in the horizontal direction of the base portion 5, and the riding portion 2 is attached to the upper side of the swing mechanism 3. The swing mechanism 3 and the drive mechanism 4 are disposed on the upper surface or in the inside of the base portion 5, and the base portion 5 itself is disposed such that the top of its convex portion is in contact with the floor surface F. .

Thus, when the user M appears on the upper surface of the boarding portion 2 in a state where the base portion 5 has a convex shape downward and this shape is placed on the floor surface F, the base on the floor surface Since the part 5 is in an unstable state (rising up and in a state of being a lawman), the user M can be boarded while being balanced. That is, if the base portion 5 is formed in such a downward convex shape, in addition to the instability of the riding portion 2, the user M becomes more difficult to sit in a stable manner, and the balance movement more effective by the user M It will be possible to

In addition, although the base part 5 to show in figure is circular shape by planar view, it is not limited to this, An elliptical shape may be sufficient. That is, the base portion 5 may have different lengths in the front-rear direction and in the left-right direction. Further, the base portion 5 may be non-circular in plan view, for example, square or hexagonal. The base portion 5 is not limited to a semicircular shape in a side view, and may be, for example, a triangular shape (angular shape) with rounded corners. That is, it may be pyramidal in perspective.

The base portion 5 has a dome-shaped (convex downward) core body 6 formed of hard plastic or the like inside, and an intermediate material 7 formed of urethane or the like is disposed on the entire lower surface of the base body 5, A covering material 8 formed of silicone rubber or the like is disposed outside the intermediate material 7.
That is, the above-mentioned intermediate material 7 covers the core 6 entirely from the lower side, and the outside of the intermediate material 7 is covered with the covering material 8; in other words, a lamination in which the covering material 8 and the intermediate material 7 are double laminated. It has a structure.
