Description

{a walking safety device that supports the lower body}

The present invention relates to a walking safety device that supports the lower body. More specifically, the present invention relates to a walking safety device that supports the lower body, and more specifically, to easily adjust the height of the swing saddle so that people who have difficulty walking due to physical abnormalities such as the waist or legs can walk safely. A walking safety device that supports the lower body and allows the swing saddle to swing left and right when walking to match the user's movements, and also absorbs external shocks when moving, thereby increasing the safety of use. This is what we want to provide.

The present invention relates to assistive devices that are generally used to help people with impaired mobility, ranging from the most basic canes and crutches to simple supports that support the body weight of a person with impaired mobility and facilitate walking while walking. It is produced, distributed and used in various ways.

In the case of the above cane or crutches, each leg is in contact with the floor, so if it is difficult to stand on your own and movement or walking is extremely difficult, it is difficult to support the body only with the cane or crutches. Equipment to assist walking was required.

Accordingly, as published in the Republic of Korea Registered Utility Model Gazette (Y1) No. 20-362325 (September 16, 2004), patients with limited mobility are provided with four legs that touch the ground to support their bodies to prevent them from falling. A walker has been developed that facilitates walking and has wheels attached to the bottom of each leg so that one can easily drag the walker without lifting it when walking. This walker was developed in Republic of Korea Patent Publication (B1) No. 10-0843484 (July 3, 2008). ), an advanced technology has also been developed that allows the bar to be installed on the lower part of the bridge so that it moves up and down to control the degree of emergence so that it can be used not only on flat ground but also on stairs.

However, the various walking aids such as the above-mentioned conventional canes, crutches, and walkers require a lot of strength on the hands and arms because they must be lifted by hand when walking and then placed in front in the direction of walking. Because it has to be supported with a hand, it causes considerable pain to the hands, arms, or armpits, so it has the disadvantage of being extremely difficult to use for the elderly and infirm. In the case of the wheeled walker, there is no need to lift it, so it requires less force, but it is necessary to hold the walker with your hands. There are a number of problems, including the disadvantage that both hands are not free because you have to push in the direction of walking.

In order to solve the above problems, the present inventor has proposed a walking assistance device in Republic of Korea Patent Publication (B1) No. 10-1699052 (January 24, 2017), which includes a fixing plate located at the bottom; A supporter hinged to the upper part of the fixing plate so that it moves back and forth at an angle; A leaf spring whose lower end is coupled to the upper end of the supporter so that the height can be adjusted by a height adjustment means and whose center is bent toward the rear and the upper end is curved toward the front; A pair of lift arms facing each other at the top of the leaf spring and hinged at an angle to open or retract horizontally with the center as the starting point), a lift spring installed downwardly at each end of the pair of lift arms, It is configured to include a lift means consisting of a connecting ring connected to the bottom of the lift spring.

Although the above-described prior art is effective in terms of use, there are inconveniences such as having to first wear a harness on the user's body in order to use it, so there is a need for improvement.
