Abstract

<P>PROBLEM TO BE SOLVED: To provide a walk aid apparatus for assisting the smooth raise of a leg and preventing the decline of the legs concerning a person who hardly raises the leg owing to the physical decline by aging or the aftereffect of cerebral infarction, etc. <P>SOLUTION: The walk aid apparatus, where a torsion spring and a coil spring are attached to fitting tools 1, 2, is attached to a waist and the bending part of each thigh. Thus the leg therefore is raised with a subtle force to raise the leg by using the characteristic of the springs (a return force). <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

Detailed Description of the Invention

  The present invention relates to a walking assistance device that makes walking easy by utilizing the characteristics of the spring by attaching and attaching a walking assistance device incorporating a spring to the waist and thigh.

  High-priced devices such as wheelchairs for the physically challenged and those requiring care, electric wheelchairs, and walking aids with sensors have been developed. However, the development of walking aids for those who have difficulty walking due to deterioration of the lower limbs due to the aging of healthy individuals is increasing. Therefore, we proceeded with the development of walking aids that can be easily installed using inexpensive materials such as springs and that can be provided at low cost.

  Conventionally, the development of wheelchairs and lower limb attachments for the physically handicapped and the development of walking aids (canes, etc.) for people who have difficulty walking can be seen. There was no development of a walking aid for people whose feet could not rise as expected due to the decline. Increasing number of cases where the feet do not go up as expected and hit the slight steps and fall asleep and need care. In the future, the aim is to prevent the increase of medical expenses and nursing costs by making it easier to walk by assisting the movement of lower limbs, which is increasing, and preventing falling. In addition, the use of a wheelchair or the like is supported by the walking assisting device so that the user can walk as much as possible because the lower limbs that have become dull move more and more.

  When a spring is inserted into the wearing device of the refracting part parallel to the joint of the walking assisting device and the foot is lowered, the operation goes against the original state of the spring, and the muscle strength of the foot is strengthened. It turns out that when the foot is raised, the spring returns to the original position, so that the foot is raised smoothly with a slight force to raise the foot.

  The invention is based on the fact that the walking assistive device that uses the characteristics of the spring is worn by a person who is unable to raise his / her legs as expected due to the deterioration of the lower limbs due to aging, cerebral infarction, etc. You can raise your feet smoothly even with the slightest effort to raise them.

BEST MODE FOR CARRYING OUT THE INVENTION

(4) As shown in FIG. 4, a torsion spring (7) is attached to a and b, and a coil spring (8) is attached to c and d.
2) As shown in Fig. 2, put (5) on the back and put the wearing device (main part) combined with (1) and (2) in close contact with the body. Squeeze at the front of and fix. In the same manner, the belt passed through C and D, and the belt passed through E and F are squeezed and fixed to the upper thigh. At the same time, squeeze the belt that passes through the toe and chin, and the belt that passes through the nail and tighten the belt to the lower thigh.
