Description

The present invention relates to training footwear used to train the muscles of the foot.

Conventionally, as footwear for training, for example, as disclosed in Patent Document 1, there is a single-tooth clog. In this geta, a tooth body having a required height is formed on the front portion of the lower surface of the bottom member, and since there is only one tooth body, the posture of the bottom member is unstable in the front-rear direction of the bottom member. .. That is, the tooth body tends to tilt in the front-rear direction with its lower end as a fulcrum. Then, after wearing the clogs on the feet, the muscles of the feet can be trained by placing the center of gravity near the toes and walking while maintaining a balance.

Jitsuzenpei 02-109401

However, in the above-mentioned single-tooth clog, the tooth body has a width close to the width of the bottom member, and the lower end of the tooth body extends linearly in the width direction of the bottom member parallel to the upper surface of the bottom member. Therefore, the posture of the bottom member is stable in the left-right direction. That is, the bottom member is unlikely to undergo a rotational movement about its axis in the front-rear direction, and is unlikely to tilt in the left-right direction with the lower end of the tooth body as a fulcrum. When the clogs are worn, even if the bottom member is slightly tilted to the left or right, the posture of the bottom member is restored to the standard posture by the tooth body, and the left and right sides of the bottom member are not applied to the bottom member from the foot. The directional posture is maintained in a standard state. Therefore, the single-tooth clogs described above are insufficient to train the leg muscles used to restore the posture of the bottom member tilted in the left-right direction to the standard posture.

The present invention has been made in view of the above circumstances, and the main purpose of the present invention is to provide footwear for training that can effectively train the muscles of the foot that resist the lateral inclination of the bottom member. To do.

It can also be shared and realized.
(First Embodiment)

1 and 2 show the first embodiment of the present invention. In the training footwear 1, the plate-shaped bottom member 2 that supports the sole of the foot and the standard posture of the bottom member 2 are at least in the left-right direction of the bottom member 2. It is provided with rod-shaped protrusions 3a and 3b provided on the lower surface of the bottom member 2 so as to be unstable.

In this embodiment, the training footwear 1 is a geta and includes a thong 4 for holding the foot F in a predetermined position on the upper surface of the bottom member 2. As shown in FIG. 1, the lengths of the two rod-shaped protrusions 3a are the same as each other, and the lengths of the four rod-shaped protrusions 3b are also the same as each other, but they are shorter than the protrusions 3a. Further, the lower end surface of the protrusion 3a is parallel to the upper surface of the bottom member 2.

The standard posture of the bottom member 2 means the posture of the bottom member 2 when the posture reference line L1 set on the bottom member 2 becomes vertical as shown in FIG. 2, and this posture reference line L1 is the training footwear 1. The training footwear 1 is held on a horizontal floor with good stability so that it can stand upright naturally, and when the training footwear 1 that holds the stability is worn, the foot F is changed to the bottom member 2. It is an axial line in the vertical direction passing through the point of action P1 of the acting load.

In FIG. 1, when the point of action P1 of the load on the bottom member 2 and the support point P2 of the bottom member 2 by the protrusion 3a are deviated in the width direction of the bottom member 2, the bottom member 2 is centered on the axis in the front-rear direction. A rotational force is generated. When a rotational force that opposes this rotational force is not applied to the bottom member 2 from the outside, the deviation in the width direction between the load acting point P1 and the support point P2 is larger than the half width (radius) of the bottom surface of the protrusion 3a. For example, the bottom member 2 tilts in the left-right direction and falls down. That is, in such a state, the standard posture of the bottom member 2 is unstable in the left-right direction of the bottom member 2. Further, if the deviation in the width direction between the load acting point P1 and the support point P2 is smaller than the half width of the bottom surface of the protrusion 3a, a posture restoring force is generated in the protrusion 3a and the bottom member 2 and the protrusion 3a fall down. However, for example, when the protrusion 3a is tilted due to unevenness of the ground or the like, the deviation in the width direction between the load acting point P1 and the support point P2 becomes larger than the half width of the bottom surface of the protrusion 3a, and the protrusion 3a and the bottom member The posture of 2 may not be restored. In this invention, even when the inclination angle of the protrusion 3a and the bottom member 2 (the inclination angle of the posture reference line L1 with respect to the vertical line) when the protrusion 3a is tilted in the left-right direction and cannot be restored is 30 degrees or less, the bottom portion It is assumed that the standard posture of the material 2 is unstable in the left-right direction of the bottom member 2.

In order to build leg muscles with the training footwear 1, wear the training footwear 1 and walk while keeping only the protrusions 3a on the ground. Then, when the protrusion 3a is tilted in the left-right direction, a restoring force is applied from the foot F to the bottom member 2 so as to restore the tilt. As a result, the muscles of the foot F are trained. When the protrusion 3a is tilted in the left-right direction, when a restoring force cannot be applied from the foot F to the bottom member 2 to restore the tilt, the protrusion 3b abuts on the ground to cause the protrusion 3a and the protrusion 3a and the bottom member 2. It is possible to prevent the bottom member 2 from being greatly tilted in the left-right direction, thereby serving to protect the ankle.
(Second Embodiment)

5 and 7 show a second embodiment of the present invention, in which the forging footwear 1 has a plurality of rod-shaped protrusions 3a and 3b detachably attached to and detachable from the bottom member 2, and a plurality of protrusions with respect to the bottom member 2. The protrusion mounting means 5 that can mount the 3a and 3b in a changeable manner is provided. The protrusion mounting means 5 is formed on the lower surface of the bottom member 2, has a plurality of groove 6 extending in the left-right direction, a screw rod 8 having a head portion 7 fitted in the groove 6, and protrusions 3a and 3b. It is provided with a female screw hole 9 formed in each of the longitudinal axis directions of the above, and a spanner engaging portion 10 formed in each of the protrusions 3a and 3b. The female screw hole 9 is formed with a female screw that matches the male screw formed on the screw rod 8, and the female screw hole 9 can be screwed into the screw rod 8.

The spanner engaging portion 10 is composed of a pair of parallel planes formed on the side surfaces of the protrusions 3a and 3b. In this embodiment, three protrusions 3a are attached to the bottom member 2, and four protrusions 3b having a height different from that of the protrusions 3a are attached to the bottom member 2, but the number of protrusions 3a and 3b is large. Is not limited to this, and a larger number of protrusions 3a and 3b may be prepared, and a plurality of protrusions having different heights other than the protrusions 3a and 3b may be prepared. ..

In order to mount the protrusion 3a on the lower surface of the bottom member 2, the head portion 7 of the screw rod 8 is inserted into the groove 6 from one end of the groove 6 in the longitudinal axis direction of the groove 6 and inside the groove 6. At that position, the female screw hole 9 of the protrusion 3a is screwed into the screw rod 8, and the protrusion 3a is rotated so that the end surface of the protrusion 3a on the screw rod 8 side is the lower surface of the bottom member 2. After advancing until it hits, hook the spanner on the spanner engaging portion 10 and tighten it. As a result, the protrusion 3a is fixed to the lower surface of the bottom member 2. When changing the position of the protrusion 3a or removing it from the bottom member 2, a spanner is applied to the spanner engaging portion 10 and the protrusion 3a is rotated in the direction opposite to that at the time of tightening. The protrusion 3a is retracted from the lower surface, and then the screw rod 8 and the protrusion 3a are moved to a required position along the groove 8 or removed from the groove 8. The protrusion 3b can also be mounted at a required position on the lower surface of the bottom member 2 in the same manner as the protrusion 3a.

In this training footwear 1, before using it, the protrusions 3a and 3b are arranged on the lower surface of the bottom member 2 so that an appropriate load is applied to the muscle to be trained of the foot F when it is worn. If the deviation in the width direction between the point of action P1 of the load from the foot F to the bottom member 2 and the support point P2 of the bottom member 2 by the protrusion 3a in the width direction becomes large, the couple generated in the bottom member 2 becomes large. , The burden on the leg muscles to counter this increases. In the training footwear 1 shown in FIG. 1, the point of action P1 of the load from the foot F to the bottom member 2 and the support point P2 of the bottom member 2 by the protrusion 3a are aligned on the same axis in the front-rear direction. The training footwear 1 shown in FIG. 4 has a larger load on the leg muscles than the training footwear 1 shown in FIG.
