Abstract

PROBLEM TO BE SOLVED: To suppress the sinking of the heel after grounding the front foot part by arranging a highly elastic falling suppressing member in the position of covering the lower part of the Achilles' tendon from back so as to extend from the heel to the foot neck. SOLUTION: An ankle winding belt part 4 is wound on the ankle K or foot neck A of a foot and engaged with the ankle K or foot neck A. A sinking suppressing member 5 is formed of a highly elastic member and arranged in the position of covering the lower part of the Achilles' tendon from back, and it suppresses the sinking of the heel by receiving a tensile load after the grounding of a front foot part F in walking or running and extending. Since the angle of the foot joint is hardly shifted from a suitable movable range, the reduction in bottom bending force can be suppressed, and the fare of extending the grounding time is also eliminated. Further, since the highly elastic sinking suppressing member 5 slightly extends according to back bending motion, and a large elastic energy is accumulated in the sinking suppressing member 5, the elastic energy is released in kicking by restoring the sinking suppressing member 5 to enhance the bottom bending force, whereby the locomotive function can be enhanced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motor function assisting structure for assisting a motor function of a foot.

[0002]

BACKGROUND OF THE INVENTION When a person walks or runs,
By rotating the ankle joint (joint of the ankle) C in a direction to bring the toe of the foot closer to the ground, that is, by bending the ankle joint C, the muscle force of the leg is transmitted to the foot to kick the ground. Therefore, in order to run fast and jump high, it is necessary to increase the plantar flexion force of the ankle joint C. The plantar flexion force of the ankle varies depending on the angle α of the ankle in FIG. During running, the plantar flexion force becomes maximum when the angle α of the ankle joint is about 130 to 160 degrees, while on the other hand, when walking, when the angle α of the ankle joint is about 110 to 130 degrees, Is the largest. Therefore, in order to maintain the optimal range of motion where the plantar flexion force is large during exercise, it is necessary to control the angle α of the ankle joint.

However, when the conventional shoes are worn, since the angle α of the ankle joint is not controlled at all, when the vertical load becomes maximum after the foot touches the ground, the heel falls due to the load (dorsiflexion). Occurs, so that the angle α of the ankle joint is smaller than the optimum movable range. Outside of the optimal range of motion, the plantar flexion force is reduced and the force to kick the ground is reduced, and the heel drop causes a decrease in the body weight, or the contact time increases, Become slow. Therefore, it causes a decrease in motor function.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a motor function assisting structure capable of enhancing a motor function by maintaining an angle of an ankle joint in an optimum movable range. It is.

[0005]

In order to achieve the above-mentioned object, the motor function assisting structure of the present invention is disposed from the heel to the ankle of the foot at a position so as to cover the lower part of the Achilles tendon from behind. After the forefoot part touches the ground when the vehicle is running, it has a highly elastic drop-preventing member that suppresses the drop of the heel of the foot by extending under load.

[0006] According to the present invention, since the dropping member having high elasticity suppresses the drop of the heel after touching the ground, that is, the dorsiflexion operation, the angle of the ankle joint is less likely to deviate from the optimal range of motion. In addition, the highly elastic drop restraining member slightly expands with the dorsiflexion operation, thereby storing a large amount of elastic energy. Therefore, when kicking out the foot, the elastic energy is released, and the plantar flexion force increases. I do.

Therefore, the term “high elasticity” in the present invention has the property of a spring that can be slightly stretched when the plantar flexion of the foot and accumulates elastic energy, and is restored when the dorsiflexion of the foot releases the elastic energy. However, it can be made of an elastomer such as sponge rubber. The Young's modulus of the material constituting the落込suppressing member varies depending human leg strength and purpose to wear, preferably about 5~300kg / cm ^2, about. 10 to 200 kg / cm ² is more preferable. In addition, the maximum breaking elongation of the drop suppressing member is generally preferably 10% or more. Further, the spring constant (tensile load / elongation) of the drop suppressing member is preferably about 15 to 900 kg / cm, and 30 to 6 kg / cm.
About 00 kg / cm 2 is more preferable.

Further, in the present invention, "at a position where the lower part of the Achilles tendon is covered from behind" means that the drop suppressing member is disposed at a position where the drop suppressing member extends at the time of dorsiflexion of the foot. The purpose of the present invention is not to consider whether the lower part of the Achilles tendon is actually covered or not, but to exclude the case where the drop-in suppressing member is arranged along the inside or outside of the ankle of the foot. Note that, if the drop suppressing member is arranged at a position that covers at least a part of the lower part of the Achilles tendon from behind, it is not necessary to cover all of the Achilles tendon, and it is a linear or rod-like or net-like member. When configured, the Achilles tendon cannot be obscured, but is within the scope of the present invention.
