Description

The present invention relates to an exercise device, and more particularly to an exercise device in which a foot is placed and stepped on with a heel.

The stepping action with a saddle, that is, the step action, is an action according to a normal walking action, is one of the basic human actions, and is closely related to the human posture. The step action in the standing position is an extension movement in which the Achilles tendon is extended and the knee is extended by depressing the heel. The basic axis of posture is a line connecting the ear to the ankle, but the step operation is an operation of extending the basic axis from the pelvis / hip joint to the ankle.

Patent Documents 1 and 2 are examples of instruments that perform an operation of placing a foot and stepping on. Patent Documents 1 and 2 disclose footwear (slippers and sandals) in which a heel portion is formed of an upper member and a lower member, and a spring is provided between these members so that the heel portion can be raised and lowered. Patent Document 1 relates to a slipper with a movement function whose main purpose is to perform stepping exercises while sitting on a chair, and Patent Document 2 relates to a sandal that eliminates an impact on the ankle and provides a comfortable wearing comfort. It does not focus on the nature of the step operation.

An object of the present invention is to provide an exercise device that enables posture correction and various exercises in a subject by paying attention to the essence of the step operation.

The technical means adopted by the present invention are:
A footrest portion having a front portion corresponding to the toe side and a rear portion corresponding to the heel side; and a bottom portion that contacts the floor surface, wherein the footrest portion has the rear portion with respect to the front portion. An exercise device that is supported by an elastic support mechanism in a state of being positioned above, and that steps on the footrest so as to place the foot on the footrest and push down the rear portion with a heel,
The footrest is flexible enough to allow twisting,
The degree of downward depression of the rear part is configured to be different between the inner part and the outer part in the width direction of the footrest part,
An exercise device that twists so that the footrest portion tilts in the width direction according to the difference in the degree of depression when stepped on;
It is.

According to the present invention, when the foot is depressed, the torsion (inclination in the width direction) of the footrest corresponding to the difference in the degree of depression acts on the leg of the subject.
When the footrest is stepped on, if the inner part of the footrest part is lowered more than the outer part, the inclination of the footrest part (inner / outer height) causes the subject's leg to adduction. More specifically, at the time of depressing, the inner axis can be rotated while extending the basic axis from the pelvis / hip joint to the ankle, which is effective in correcting the O-leg / groin.
If the outer part of the footrest part is lowered more than the inner part when stepped on, the inclination of the footrest part (inner high / outer low) causes abduction of the subject's leg.
In one aspect, when no external force is applied, the footrest (especially the rear part) is in a substantially horizontal posture in the width direction, and is twisted so as to tilt in the width direction when stepped on and is inclined in the width direction.

  As an aspect in which the degree of downward depression of the rear part differs between the inner part and the outer part in the width direction of the footrest part, for example, (a) Depression is movable between the inner part and the outer part of the footrest part. If there is a difference in the area (movable amount to push down), (b) if there is a difference in strength between the inner part and the outer part of the elastic support mechanism, (c) how the force is applied when stepping on the inner part and the outer part (As a result, when stepping on, one is easier to lower than the other), or any combination of these.

In one aspect, by making the stepping movable range (pressing movable amount) of the inner portion in the width direction of the footrest portion different from the stepping movable range (pressing movable amount) of the outer portion, the degree of downward pressing is achieved. Make a difference.
For example, the strength of the depression is the same inside and outside in the width direction, but the depression on one side is restricted by a stopper or the like, that is, when it is lowered to some extent, the depression is further restricted by hitting the stopper.
In one aspect, the rear portion of the footrest and the bottom are opposed to each other, and the upper surface of the bottom is inclined in the width direction.
In this case, when the slope of the upper surface of the bottom is internal low / external high, the inclination of the footrest part is internal low / external high, causing the subject's leg to addendum, and the slope of the top of the bottom is When the inner height is higher or lower than the outer height, the footrest is inclined at the inner height or the outer height, causing the subject's leg to be abducted.
Alternatively, when the elastic support mechanism is a leaf spring, a stopper may be provided to restrict the rotation angle (the amount of collapse or sink) of the leaf spring.

In one aspect, the force for pushing down the rear portion supported by the elastic support mechanism is made different between the inner portion and the outer portion in the width direction of the footrest portion, thereby lowering the lower portion. The degree is different.
In one aspect, it is comprised so that the force for pushing down an inner side part may be smaller than the force for pushing down an outer side part, and a test subject's leg is caused to adduction.
In one aspect, it is comprised so that the force for pushing down an outer side part may be smaller than the force for pushing down an inner side part, and a test subject's leg is caused to abduct.

In one aspect, the elastic support mechanism includes an inner elastic support member that supports an inner portion of the rear portion, and an outer elastic support member that supports an outer portion of the rear portion.
In one aspect, the force for pushing down the inner elastic support member is different from the force for pushing down the outer elastic support member.
In one aspect, the inner elastic support member and the outer elastic support member have different strengths.
In one aspect, the strength of the inner elastic support member is smaller than the strength of the outer elastic support member.
In one aspect, the strength of the inner elastic support member is greater than the strength of the outer elastic support member.

In one aspect, when stepping on, the point of action of the force for pushing down the inner elastic support member and the point of action of the force for pushing down the outer elastic support member are in the length direction of the footrest portion. It's off.
In this case, the inner elastic support member and the outer elastic support member may have different strengths or the same strength.

In one aspect, the said footrest part is formed from the elastic member. When the elastic member forms part or all of the elastic support mechanism, the elastic member may be separate from the elastic support mechanism.
In one aspect, a part or all of the elastic support mechanism is formed of a leaf spring.
In one aspect, the said inner side elastic support member and the said outer side elastic support member are formed from the leaf | plate spring.
In one aspect, the footrest part forms the leaf spring.
In one aspect, the bottom and the footrest are integrally formed, and a leaf spring is formed from the bottom and the footrest.
In one aspect, the rear part includes an inclined surface extending in a rising direction toward the rear with respect to the front part, and the rear part is rotatable with respect to the front part.
The fact that the rear part is rotatable with respect to the front part includes rotation by elastic deformation (bending), rotation through a shaft (hinge shaft), and the like.
In one aspect, the elastic support mechanism is formed of a coil spring.
In one aspect, the elastic support mechanism is formed from a cushion.

The present invention is configured such that the degree of downward depression of the rear part of the footrest part is different between the inner part and the outer part in the width direction of the footrest part. According to the present invention, the footrest portion is twisted so as to be inclined in the width direction. According to the present invention, the footrest portion is twisted (inclination in the width direction) according to the degree of depression when stepped on. Acts on the subject's leg.

When the footrest is stepped on, if the inner part of the footrest part is lowered more than the outer part, the inclination of the footrest part (inner / outer height) causes the subject's leg to adduction. More specifically, at the time of depressing, the inner axis can be rotated while extending the basic axis from the pelvis / hip joint to the ankle, which is effective in correcting the O-leg / groin. Each time the heel is stepped on, the heel is turned inward (twisted) to the inner side where the strength is weak, so it is corrected from the groin to the inner groin, contributing to the construction of O-legs and beautiful legs. This is effective for people who wear down the outside of the shoe sole.
Human walking is landing from the heel, and the movement of the center of gravity is closely related to the movement of the heel. Tightrope walks and walks on balance stations are in a state where the posture balance due to the movement of the center of gravity is consistent. That is, when the heel is turned inward toward the center axis (center of gravity) of the body, it is possible to correct the crotch walking and make a correct posture.
Many ankle sprains are caused by the extremely inconsistent state of movement of the center of gravity, “extreme external rotation (rotation)”. However, the present invention provides an ankle sprain, knee and hip joint deformation, and falls Can contribute to the prevention of injuries.

If the outer part of the footrest part is lowered more than the inner part when stepped on, the inclination of the footrest part (inner high / outer low) causes abduction of the subject's leg. Regardless of whether the subject's leg is inwardly or abducted, the exercise apparatus according to the present invention has a simple configuration, and is portable and easy to use, unlike a large fixed stepper. Stepping exercises can be performed anywhere while cooking, washing, and stepping exercises can be performed anywhere. According to the exercise apparatus of the present invention, muscle training of the lower body such as calf muscles, thigh muscles, and buttocks muscles can be performed while “hip”, and of course, most of the muscles include the buttocks and thighs. Therefore, dietary effect can be expected by improving basic metabolism by muscle training.

[A] Embodiment 1
A first embodiment according to the present invention will be described with reference to FIGS. The exercise apparatus according to the first embodiment has a slipper shape as shown in FIG. 4, and includes a footrest portion 1, a bottom portion 2 whose bottom surface is in contact with the floor surface, and a spring provided on the front side of the footrest portion 1. (The part covering the instep) 3 is provided. In FIG. 1 and FIG. 2, for convenience of explanation, the honeycomb 3 that is the upper portion of the slipper is omitted.

The footrest portion 1 includes a front portion 10 corresponding to the toe side, a rear portion 11 corresponding to the heel side, an inner edge portion 12 on the thumb side (the thumb ball side, the arch side), and the little finger side (the little finger ball side). And an outer edge portion 13. The upper surface 110 of the rear portion 11 of the footrest portion 1 is an inclined surface extending in a rising shape toward the rear with respect to the front portion 10, and the upper surface 100 of the front portion 10 of the footrest portion 1 is substantially horizontal ( Gently sloping). The soles of the feet are placed on the upper surfaces 100 and 110 of the footrest portion 1.

The bottom part 2 has the same planar shape as the footrest part 1, a front part 20 corresponding to the toe side, a rear part 21 corresponding to the heel side, an inner edge part 22 on the thumb side (arch side), and a little finger side The outer edge 23 of the. The front part 10 of the footrest 1 and the front part 20 of the bottom 2 are integrated. In the footrest portion 1 and the bottom portion 2, the front-rear direction is the length direction and the inner and outer directions are the width direction.

In a state where no external force is applied, the rear part 11 of the footrest 1 and the rear part 21 of the bottom 2 are vertically spaced apart from each other, and the lower surface of the rear part 11 of the footrest 1 is the bottom part of the rear part 21 of the bottom 2. It is in a state of floating upward with respect to the upper surface.

The footrest portion 1 is supported by a leaf spring 4 that is an elastic support mechanism in a state where the rear portion 11 is positioned above the front portion 10 and floats above the rear portion 21 of the bottom portion 2. Yes. FIG. 3 shows one embodiment of the leaf spring 4. In one aspect, the leaf spring 4 is incorporated in the footrest 1 and the bottom 2. The leaf spring 4 includes a base 40 extending horizontally and an inclined portion 41 rising in an inclined manner from the base 40 toward the rear, so that the base 40 extends from the front portion 20 of the bottom portion 2 into the rear portion 21. The inclined portion 41 is located in the rear portion 11 of the footrest portion 1.

1, 2, and 4 show a state in which no external force acts on the exercise equipment. From this state, the foot is placed on the footrest 1 and stepped on to push down the rear portion 11 with a heel. The rear part 11 of the foot part 1 moves downward toward the rear part 21 of the bottom part 2 and then raises the heel, so that the rear part 11 of the footrest part 1 moves upward by the elastic force of the leaf spring 4. 2 and FIG. 4 are restored.

The rear part 11 of the footrest 1 has the same thickness throughout and extends horizontally in the width direction (the direction connecting the inner edge 12 and the outer edge 13). The thickness of the rear portion 21 of the bottom 2 is thin on the inner side in the width direction and thick on the outer side in the width direction. The bottom surface of the bottom portion 2 is a horizontal surface, the height of the inner edge portion 22 is lower than the height of the outer edge portion 23, and the upper surface of the bottom portion 2 is an inclined surface 210 with inner and lower heights. The distance between the inner portion of the lower surface of the footrest portion 1 and the inner portion of the upper surface of the bottom portion 2 is larger than the distance between the outer portion of the lower surface of the footrest portion 1 and the outer portion of the upper surface of the bottom portion 2. The stepping movable range of the inner portion in the width direction of the mounting portion 1 is larger than the stepping movable range of the outer portion.

The footrest 1 (including the leaf spring 4) is flexible enough to allow torsion, and by this twist, the rear portion 11 of the footrest 1 can be rotated or tilted about the major axis. By doing so, the rear part 11 rotates and the upper surface is inclined. When the foot is placed on the footrest 1 and the toe side is fixed (stable), and the foot is pushed down so that the rear portion 11 is pushed downward, the rear portion 11 of the footrest 1 is horizontally oriented in the width direction. The torsion of the footrest 1 (inner low / outer height) causes the addendum to the subject's leg. In the case where the elastic support mechanism is formed from a leaf spring, the leaf spring itself may be configured to have a twisting tendency in a desired direction (to encourage inward or outward rotation). For example, the rotation base end portion (hinge portion) of the leaf spring may be provided with an angle (angled with respect to the short axis perpendicular to the long axis of the footrest portion). Further, the leaf spring may be arcuate or arcuate (boomerang) in plan view.

How to use exercise equipment will be explained. In the standing posture, one leg is lowered later, the lowered leg is placed on the footrest 1 and pushed down so that the rear part 11 of the footrest 1 is stepped on with the heel. A so-called hip-up step is performed in which the region 11 is lifted. The treading movement promotes inversion, and when stepping on, the inner axis is extended while extending the basic axis from the pelvis / hip joint to the ankle to correct the O-leg / groin. Repeating this while doing step exercises will provide a hip-up effect and a diet effect, and stepping exercises will improve O-legs / groins. The exercise apparatus according to the present embodiment is portable, unlike a fixed large stepper or the like, and can easily perform a step exercise “while” anywhere. Further, footwear (sandals) may also be used. A jump step may also be performed with both feet aligned.

[B] Embodiment 2
5 and 6, the elastic support mechanism that supports the rear portion 11 of the footrest 1 is an inner elastic support member that supports an inner portion in the width direction of the rear portion 11 of the footrest 1. 4 A of leaf | plate springs and the outer side leaf | plate spring 4B which is an outer side elastic support member which supports the outer side part of the width direction of the back part 11 of the footrest part 1 are provided. In the illustrated embodiment, the inner leaf spring 4 </ b> A and the outer leaf spring 4 </ b> B are juxtaposed in the width direction of the footrest 1.

In the illustrated embodiment, an inner leaf spring 4A provided outside the footrest portion 1 and the bottom portion 2 is provided between the lower surface in front of the rear portion 11 of the footrest portion 1 and the upper surface of the rear portion 21 of the bottom portion 2. The leaf spring 4B is shown. When providing an elastic support member separately for the footrest 1 and the bottom 2, a torsion spring, a coil spring, or a cushion may be used in addition to the leaf springs 4A and 4B. Note that, as in the first embodiment, these internal and external leaf springs may be incorporated in the footrest 1 and the bottom 2. For example, the leaf spring shown in FIG. 3 may be made narrow to form an inner leaf spring and an outer leaf spring, which may be incorporated in the footrest portion 1 and the bottom portion 2. As shown in the left diagram of FIG. 6, a contact portion 111 such as a cushion that contacts the floor surface may be provided on the lower surface of the rear portion 11 of the footrest portion 1. Moreover, you may extend the back part 21 of the bottom part 2 so that the back part 11 of the footrest part 1 may be opposed (it shows with a dotted line in FIG. 5). The footrest 1 and the bottom 2 may also be formed of an elastic member (for example, a leaf spring is incorporated as in the first embodiment), and the leaf spring may be formed separately from the leaf springs 4A and 4B. .

The strength of the inner leaf spring 4A is smaller than the strength of the outer leaf spring 4B, and the inner leaf spring 4A is crushed by a lower pressing force than the outer leaf spring 4B. That is, the rear part 11 of the footrest 1 is such that the inner part is more likely to be lowered than the outer part. Making the strength of the inner leaf spring 4A different from the strength of the outer leaf spring 4B can be obtained by making a difference in the thickness of the leaf spring, making a difference in the size (eg, width) of the leaf spring, and the like.

The footrest 1 is flexible enough to allow torsion. The foot rests on the footrest 1 and the toe side is fixed (stable), and the rear portion 11 is pushed downward with a heel. , The rear portion 11 of the footrest 1 is grounded while twisting so as to incline from the horizontal posture to the inner low / outer height in the width direction, and the foot rest 1 is inclined (inner low / outer). High) causes adduction in the subject's leg.

How to use exercise equipment will be explained. In the standing posture, one leg is lowered later, the lowered leg is placed on the footrest 1 and pushed down so that the rear part 11 of the footrest 1 is stepped on with the heel. A so-called hip-up step is performed in which the region 11 is lifted. The treading movement promotes inversion, and when stepping on, the inner axis is extended while extending the basic axis from the pelvis / hip joint to the ankle to correct the O-leg / groin. Repeating this while doing step exercises will provide a hip-up effect and a diet effect, and stepping exercises will improve O-legs / groins. The improvement angle is indicated by a white line on the right side of FIG. Further, the exercise apparatus according to the present embodiment is portable, unlike a fixed large stepper or the like, and can easily perform a step exercise “where” anywhere. A counter may be installed on the ground surface to count the number of times. As in the first embodiment, the jump step may be performed by aligning both feet that may also be used for footwear such as sandals.

As described above, in the second embodiment, the strength of the inner leaf spring is weakened, and the strength of the outer leaf spring is increased, so that the footrest portion 1 is inclined and deformed inward by a stepping motion from the toe to the heel. It encourages adduction. The inner leaf spring 4A, which is the inner elastic support member, and the outer leaf spring 4B, which is the outer elastic support member, may be formed with substantially the same strength, and the stepping movable range may be different. For example, when the outer leaf spring 4B is provided with a stopper and the rear portion 11 of the footrest 1 is pushed down with a heel, the inner leaf spring 4A and the outer leaf spring 4B sink almost simultaneously until a certain amount, and thereafter the outer leaf spring 4B. The lowering of 4B may be regulated by a stopper, and only the inner leaf spring 4A may sink, and the rear portion 11 of the footrest 1 may be twisted to the inner and outer heights. Further, as a modification, a slit is formed in the longitudinal direction at the central portion in the width direction of the inclined portion of one wide leaf spring, and is divided into an inner inclined portion and an outer inclined portion, and the lowering of the outer inclined portion is stopped by a stopper. It may be regulated.

[C] Embodiment 3

As shown in FIG. 7, an inner leaf spring 4 </ b> A and an outer leaf spring 4 </ b> B are provided in the width direction between the rear portion 11 of the footrest portion 1 and the rear portion 21 of the bottom portion 2. The inner leaf spring 4A and the outer leaf spring 4B have the same shape and the same spring strength. On the upper surface of the bottom portion 2, an inner guide 5A and an outer guide 5B are juxtaposed in the width direction. The inner leaf spring 4A can move in the length direction on the inner guide 5A, and the outer leaf spring 4B can move in the length direction on the outer guide 5B (inner leaf spring 4A, outer leaf spring). The point of action moves as the position of 4B changes in the length direction).

The inner leaf spring 4A and the outer leaf spring 4B are movable between a first position on the front side and a second position on the rear side, and are in the first position in a state where no pressing force acts, It is urged from the second position toward the first position, automatically moves from the first position to the second position in accordance with the pushing pressure at the time of depressing, and when the heel is raised, the second position is Automatically move to position 1. The action point moves when the inner leaf spring 4A and the outer leaf spring 4B move in the length direction. The inner leaf spring 4A and the outer leaf spring 4B can regulate movement on the inner guide 5A and the outer guide 5B by stoppers (not shown), respectively.

When the rear part 11 of the footrest 1 is pushed down with a heel while the outer leaf spring 4B is fixed to the first position with a stopper, the inner leaf spring 4A moves from the first position toward the second position. By moving the action point toward the heel, the inner leaf spring 4A is crushed more than the outer leaf spring 4B, so that the rear portion 11 of the footrest 1 is twisted so as to incline to the inner low and outer height, Encourage rollover.

When the rear part 11 of the footrest 1 is pushed down with a heel while the inner leaf spring 4A is fixed to the first position with a stopper, the outer leaf spring 4B moves from the first position toward the second position. By moving the action point toward the heel, the outer leaf spring 4B is crushed more than the inner leaf spring 4A, so that the rear portion 11 of the footrest portion 1 is twisted so as to incline to the inner height and the outer height, Encourage rollover.

As described above, when the pedal is depressed, there are an action point of force for pushing down the inner leaf spring 4A as the inner elastic support member and an action point of force for pushing the outer leaf spring 4B as the outer elastic support member downward. By shifting in the length direction of the footrest part 1 and the bottom part 2, the leaf spring on the rear side is easily crushed. Further, by adjusting the first position on the front side and the second position on the rear side of the inner leaf spring 4A and the outer leaf spring 4B, the torsion angle of the inward rotation or the outer rotation can be adjusted. Only one of the inner elastic support member and the outer elastic support member may be movable in the length direction of the footrest portion 1 and the bottom portion 2. For example, the outer leaf spring 4B is fixed (the outer guide 5B is provided). No), only the inner leaf spring 4A may be movable in the length direction.

FIG. 8 relates to a modification of the embodiment shown in FIG. Similarly to the embodiment shown in FIG. 7, the inner leaf spring 4 </ b> A and the outer leaf spring 4 </ b> B are movable in the length direction of the footrest portion 1 and the bottom portion 2. The length of the bottom 2 is shorter than the length of the footrest 1, and the inner leaf spring 4A and the outer leaf spring 4B are slidable with respect to the rear end of the bottom 2, and the front side ( The first position is drawn into the rear end of the bottom portion 2 and the second position is on the rear side (projected from the rear end of the bottom portion 2). The movement of the inner leaf spring 4A and the outer leaf spring 4B can be restricted. When the action point of the outer leaf spring 4B is on the B side and the action point of the inner spring 4A is on the A side, the rear part 11 of the footrest 1 is twisted inward by the stepping motion from the toe to the heel, so Prompt. Since the basic usage of the exercise apparatus according to the third embodiment is the same as that of the first and second embodiments, the description thereof is omitted.

FIG. 12 shows a corrective exercise device that corrects internal and external rotations by stepping from the toes to the heel. Leaf springs are provided at both ends of a common shaft extending in the width direction of the footrest 1 and the bottom 2. The shaft is located at the pivot point of the leaf spring. Specifically, an inner leaf spring 4A is provided at the inner end of the shaft, and an outer leaf spring 4B is provided at the coaxial outer end.

The inner leaf spring 4 </ b> A and the outer leaf spring 4 </ b> B rotate in conjunction with the same torque regardless of which force is applied. When the rear part 11 of the footrest part 1 is stepped on with a scissors, the center of gravity that rotates is applied to the outer leaf spring B, but the inner spring A collides with the outer spring B by the same axis, so the rear part of the footrest part 1 11 descends in parallel. The outward rotation force of the O leg is corrected by being divided by the inner leaf spring A = the outer leaf spring B while being compressed.

Here, when two springs having the same specification are provided on the inner and outer sides, the footrest portion is deformed on the displaced center of gravity side, and the O leg is promoted. In addition, when an internal / externally integrated spring is installed, (a) if the spring is weak, the footrest is deformed to the displaced center of gravity and the O-leg is promoted. When the spring is strong, it is too hard to step on, the range of motion is narrow, and effective exercise cannot be performed. The embodiment shown in FIG. 12 solves these problems.

The first exercise device and the second exercise device (for example, the exercise device shown in FIG. 12) can be applied to a body part other than the foot part such as a seat surface correction as a set of left and right. An elastic support mechanism composed of a leaf spring functions as a cushion, and can prevent a posture failure in which the seat is bent. In this case, the term “foot rest” can be replaced with “body rest” or “butt rest”.

[F-3] Other Embodiments Still another embodiment will be described with reference to FIG. In this aspect, the exercise apparatus includes a footrest portion 1 having a front portion 10 corresponding to the toe side and a rear portion 11 corresponding to the heel side, and a bottom portion 2 that contacts the floor surface, and the footrest portion 1. The lower surface and the upper surface of the bottom surface 2 are joined and integrated. The bottom surface of the bottom surface 2 is a horizontal plane. In FIG. 13, only the footrest portion 1 and the bottom portion 2 are shown, and other elements are omitted, but as an exercise device having such a footrest portion 1 and the bottom portion 2, footwear such as slippers and sandals is provided. Can be illustrated. In addition, you may comprise the footrest part 1 and the bottom part 2 from one member.

On the upper surface of the footrest 1, the height of the outer edge 13 is higher than the height of the inner edge 12, and the height of the rear part 11 is higher than the height of the front part 10. The upper surface of the part 1 is a slanted surface with inner and outer heights and front and rear and rear heights as a whole. In one aspect, the inclination gradient (front-rear direction and width direction) of the upper surface 110 of the rear part 11 is larger than the inclination gradient (front-rear direction and width direction) of the upper surface 100 of the front part 10. The upper surface itself of the head is twisted in a state where no external force is applied. The inclination of the upper surface 100 of the front portion 10 includes horizontal, and in one aspect, the upper surface 100 is substantially horizontal and may be slightly physiologically inclined. Each of the top surfaces 100, 110 may not necessarily have a uniform slope, and within the top surface 100, the slope of one portion may be different from the slope of the other remaining portions, and the slope of a portion within the top surface 110. May be different from the slope of the other remaining portions. For example, the gradient of the rear end portion and the outer end portion of the upper surface 110 may be made gentle (that is, close to a horizontal plane).

The upper surface 110 of the rear part 11 of the footrest 1 is higher than the upper surface 100 of the front part 10, and the upper surface 110 of the rear part 11 is elastically supported by a buffer member such as an elastic cushion. In one aspect, the footrest portion 1 is entirely composed of a member that can be elastically deformed by a load (an elastic member, a cushioning member such as a cushion), and further allows twisting from a twisted posture where no external force acts. It has such flexibility. The upper surface of the footrest portion 1 is supported by an elastic support mechanism (the elastic member of the rear portion 11 of the footrest portion itself becomes an elastic support mechanism) with the rear portion 11 positioned above the front portion 10. For example, when the exercise equipment is footwear, during walking, an exercise is performed such that the foot is placed on the footrest 1 and the rear portion 11 is pushed downward with a heel.

The degree to which the rear part 11 is pushed downward is configured to be different between the inner part and the outer part in the width direction of the footrest 1, and depending on the difference in the degree of depression when stepped on (when walking). Thus, the footrest 1 is twisted so as to be further inclined in the width direction. More specifically, the degree of downward pressing of the rear portion 11 differs between the inner portion and the outer portion in the width direction of the footrest portion due to the movement of the center of gravity due to the twist of the footrest portion 1 when the foot is placed. (In the embodiment shown in the figure, the center of gravity acts on the inner part and is pushed down), and when the foot is stepped on (walking), the footrest portion further tilts in the width direction according to the degree of depression. Twist like. The degree of depression in the width direction at the rear part 11 is greater than the degree of depression in the width direction at the front part 10 (the thickness of the rear part 11 of the footrest 1 is greater than the thickness of the front part 10; It can also be influenced by how the load is applied to the mounting portion 1), and the degree of depression in the width direction of the front part 10 and the rear part 11 is different (the rear part 11 sinks greatly with respect to the front part 10). This contributes to twisting of the mounting portion 1.

As described above, when the foot is placed on the footrest portion 1 that has been twisted from the beginning, the center of gravity moves at the rear portion 11 and the inner portion of the rear portion 1 is elastically deformed and sinks. The amount of sinking (moving range of depression) depends on the height and hardness of the elastic cushion, which is an elastic support mechanism, but if the sinking amount is large, the amount of further twisting is large, and if it is small, further twisting is performed. The amount is small. An appropriate amount of sinking (stepping range of motion) is appropriately designed by those skilled in the art. For example, in general, it is desirable that the amount of sinking (stepping range of motion) is small.
