Description

{Assistance device for walking}

The present invention relates to a walking aid, and more particularly, it relates to a walking assistance device for supporting a weight of a person who is uncomfortable in walking due to a body abnormality such as a waist or a leg so that walking can be performed smoothly, And the like.

Generally, ancillary devices used to assist persons with mobility impairments include, but are not limited to, the most basic walking sticks, such as a crutch such as Korean Patent Publication No. 70633 (published September 15, 1999) Those who act as simple supporters to support the weight during walking and to facilitate walking have been produced, distributed and used variously for a long time.

In the case of the above mentioned cane or crutches, it is difficult to support the body only on a cane or a crutch when the foot or the crutch is in contact with the floor, As shown in Practical New Design No. 362325 (published on September 16, 2004), to support walking, patients with uncomfortable mobility should be equipped with four legs touching the ground, A walker has been developed in which a wheel is attached to the lower part of each leg so that the walker can be easily carried without lifting the walker. Such a walker is disclosed in Korean Patent No. 843484 (published on July 3, 2008) As shown in FIG. 4, the bar is installed at the lower part of the leg so as to be vertically moved up and down, In addition, advanced technology was developed for use in stairs as well.

However, in the conventional walking, crutches, walkers, and the like, various types of walking aids are required to be held by hand while walking, So that it is very difficult to use for the elderly. In the case of the walker with the wheel, it is not necessary to lift it, so that the force is small. However, It is necessary to push it in the direction of progress, so it is not free of both hands.

The present invention has been made to solve the above-mentioned problems of the prior art, and it is an object of the present invention to solve the problem that the conventional walking aids are unstable when walking and can not support the body properly, And it is possible to prevent the specific part of the body supported by the hand, arm, armpit and the like from being pressed and suffering while solving the trouble of lifting the auxiliary device with the both hands and putting it forward in the forward direction For the elderly who have no power, it is easier and more convenient to walk without pain. In order to solve the problem that you can not do other things by hand, you need to use both hands to walk with both hands. In order to provide a walking aid device, It is the completion of the task.

In order to achieve the above object, according to the present invention, there is provided a walking aid apparatus comprising: a supporter hinge-coupled to an upper portion of a lower fixed plate so as to be angularly moved back and forth; A leaf spring having a lower end connected to the upper end of the plate spring and a lower end connected to the upper end of the leaf spring, A lift means provided with a pair of lift arms hinged to each other so as to move in a downward direction, a lift spring installed downwardly at an end of each of the pair of lift arms, and a lift means having a connection ring connected to a lower end of the lift spring;

A compression coil spring hung on the upper end of the supporter so as to be supported so as to be raised, and a compression coil spring installed on the upper end of the supporter so as to be lifted and lowered from the front of the supporter, A vertical slide guide provided so as to be elastically supported by the vertical slide guide, and a slide block which is vertically slidable forward or downward from the front of the vertical slide guide and is fixed by a fixing means, facing each other on both sides and being angularly moved horizontally, A lift means provided with a pair of hinge-coupled lift arms and a lift means provided with a lift spring installed downwardly at an end of each of the pair of lift arms and a linkage connected to a lower end of the lift spring;

A supporter hingedly coupled to the upper portion of the lower portion of the fixed plate so as to be angularly moved back and forth; a plate provided on one side of the fixed plate so as to be rotatable on the upper side of the supporter, A vertical sliding guide provided so as to be resiliently supported by a compression coil spring at the upper end of the supporter while being installed to be lifted up from the front of the supporter; And a pair of lift arms which are hinged to each other so as to horizontally expand or contract in such a manner as to move horizontally with the center as a starting point are provided on the front side of a slide block configured to be slid up or down or fixed by fixing means, Each of the ends Is characterized in that each; bit spring and the one included the lifting means is provided connected to the lower connection link provided in the lift spring.

According to the specific means for solving the above-mentioned problems, the walking aid device of the present invention is capable of stably walking without giving a burden to the user when the user is uncomfortable such as a waist or a leg, With the help of both hands lifting the ancillary device and putting it forward, it is possible to solve the troublesome work and prevent the pain of the specific parts of the body supported by the hand, arm and armpit, It is possible to maximize the ease of use by making it easy and convenient to use while walking without pain, and since it is necessary to walk using both hands when walking using the auxiliary devices, According to the gait assist device, it does not support the body with both hands. Because hands are therefore free to act required by lifting the simple things while walking hand-in will be able to ship more convenience.

The walking aid device according to the present invention, which provides improved comfort during walking, can separate the traction part from the moving support part when the upper part is seated on a chair or a bed, besides walking, and when the seat part is coupled with a fixed support part such as a chair or a bed, It is possible to improve the usability by diversifying the applications because it can support the body. In addition, it is possible to improve the spinal diseases by pulling the vertebrae's spine, and in addition to the above, The general public can use it for a variety of purposes such as a walking exercise or a leisure sports.
