JPH09122180A - Foldable wheelchair whose seat surface is vertically movable - Google Patents

Abstract

PROBLEM TO BE SOLVED: To substantially widen the action range of a wheelchair user, to pick up an object on a floor by himself/herself by lowering a seat surface and to eliminate the need of raising the roof of an automobile since the seat surface is lowered at the time of getting on the automobile while staying in the wheelchair. SOLUTION: This wheelchair is bisected by the seat surface and a chassis part, the joining part of both is connected by a sliding post 20 and a slider, and a mechanism for winding up a lift wire 14 by a lift handle 10 attached to the seat surface and raising the seat surface is provided. A sliding wire 14 is spread in an X shape so as to perform an operation well-balancedly on the left and right, the wire is fixed by slider parts on the left and right so as to perform the operation in an equal distance and constitution is performed by a sub link length-calculated so as not to detach the sliding wire 14 at the time of folding or the like.

Description

Detailed Description of the Invention

[Conventional problem store] The conventional wheelchair is lightweight and foldable, and there is no wheelchair that can raise and lower the seat surface, so it is difficult for the user to dispose of what is falling on the floor, and when doing kitchen work, I find it inconvenient because I cannot adjust the height even when I work in the workplace.

EFFECTS OF THE INVENTION According to the present invention, the action range of a person with a disability becomes extremely wide, for example, when the seat surface is lowered to pick up an object on the floor, and when it is placed on a vehicle in a wheelchair, the vehicle is significantly No need to remodel. Since the seat surface operates high, you can adjust the kitchen, desk, etc. to an appropriate height by yourself, so there is no need to modify equipment. When hiring a person with a disability, the company does not need to modify the workbench or the like at the height of the wheelchair, which leads to an increase in the employment rate. In addition, for elderly people who cannot walk independently, it is a multifunctional device that can be adjusted to a height that fits the body of the person and can run autonomously while sitting, and can prevent bedridden and prevent blur.
