Description

  The present invention relates to an ankle joint exerciser that increases the flexibility of an ankle joint.

The human body absorbs gravity from the top to the bottom and the pressure from the ground in five positions of the cervical vertebra, lumbar vertebra, hip joint, knee joint and ankle joint. All five locations are very important, but when the ankle joint becomes stiff and the toes can no longer be raised, even a slight step can be crushed and cause a fall.
Especially for elderly people, falling often causes fractures, and we believe that prevention is more important than anything else.

Those with normal ankle joints have no pain or deformation in their knees and hip joints. However, elderly people tend to lose the flexibility of their ankle joints, and falling over often causes fractures, but no effective measures have been shown.

Although there is a foot correction tool disclosed in Patent Document 1 as an instrument that is attached to the ankle or the like and prevents falling, there is a concern that there are disadvantages such as being troublesome and poor blood circulation.

In this bent state, the toe side of the ankle joint training tool 1 is pulled upward and the toe is raised. In this bent state, since the inclined surface 12 is in contact with the floor, excellent stability can be obtained when the ankle 4 is bent. Thus, by using the ankle joint training tool 1, it is possible to easily maintain the same state (see FIG. 11) that the user's foot 4 is crouched. Thus, in this embodiment, the elastic member 6 and the inclined surface 12 constitute a bending direction urging means.

  FIG. 10 is a photograph showing a state where the user wears the ankle joint training device 1 on the foot 4 and makes the ankle extend (see arrow E (extension direction) in FIG. 7). In FIG. 10, the curved surface 11 in the covering portion 9 is in contact with the ground and the ankle 4 is extended. In the present embodiment, the first extension assisting surface 10 is provided so that the ankle joint training tool 1 can be used without imposing a burden on the ankle even if the ankle joint is hard.

Further, in this embodiment, a second extension assisting surface 13 that is an extension direction urging means is formed on the toe side of the base portion 3. The second extension assist surface 13 is flush with the first extension assist surface 10 and extends at a predetermined angle θ with respect to the back surface 7.
The user's ankle can be stably held in the extended state by grounding the first extension auxiliary surface 10 and the second extension auxiliary surface 13. This extended state is the same as the state where the user is sitting straight (see FIG. 11).

As described above, by using the ankle joint training tool 1, the user can maintain the ankle 4 in a bent state and an extended state.
Further, the curved surface 11 continuous with the second extension assisting surface 13 constitutes an extension direction urging means. The user can further extend the ankle by rotating the foot 4 in the direction of arrow E (extension direction) and grounding the curved surface 11. Thus, by providing the 1st and 2nd extension assistance surfaces 10 and 13 and the curved surface 11, a user can perform an ankle extension exercise | movement stably in steps.
