Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a device for ascending and descending stairs while in a wheelchair. Traditionally, going up and down the stairs while in a wheelchair requires a large number of six people to carry the person up and down the stairs.

The wheelchair user felt inconvenienced, unable to even go out for fun due to the pain of inconveniencing six other people. The present invention was invented to eliminate the physical inconvenience of wheelchair users as well as the inconvenience of movement.

The structure is explained as follows: (1) Parallel sliding hydraulic cylinder girders (1) (2) Ports for attaching them to both sides of the wheelchair Parallel sliding hydraulic cylinder girders (1) (2) with multi-stage cylinder legs (3) (4) 8. Attach the horizontal steady stop (8) to prevent the parallel sliding hydraulic cylinder feet (3) (4) from swinging sideways. The present invention, in which a grounding part (7) made of hard rubber or the like is attached to the ground, solves this problem with a device having such a structure. All power is generated by using the fluid pressure sent from the fluid pressure unit and space. It can also be automated by controlling the flow pressure with a computer or the like.

To explain the figures, see Figures 15 to 22.
External parallel flow pressure cylinder girder (1) (2) (hereinafter referred to as the parallel girder) is moved forward as far as it will go. A door that stops the wheelchair directly in front of the first step of the stairs (hereinafter referred to as the first step). Inner parallel girder (2) Lower multi-stage hydraulic pressure cylinder foot (3) (hereinafter referred to as multi-step foot) reaches the height above the first step 2. Move the wheelchair forward on the outer parallel girder (1) until the inner parallel girder (2) lower multi-step leg (3) hits the second step above the first step. The inner parallel girder (2), the lower multi-step foot (3), the inner parallel girder (2) on the lowest step, the outer parallel girder (4), and the lower multi-step foot (4)
1) Raise the wheelchair in parallel to the height where the lower multi-step leg (3) rests on the second step. Outer parallel girder (1) The lower multi-step leg (3) places the wheelchair on the third step above the second step.
Move the wheelchair forward with the inner parallel girder (2) until it hits a step. Move the outer parallel girder (1) lower multi-step foot (3) onto the second step. Move the wheelchair until the inner parallel girder (2) lower multi-step foot (3) reaches the height of the 8th step. Move the wheelchair forward with the outer parallel girder (1) until it hits the inner parallel girder (2), lower multi-step leg (3) is on the third step, then move the wheelchair forward (inner parallel girder (2), lower multi-step leg (4), ri 1st) At the top of the stairs, the wheelchair can be raised until the outer parallel girder (1) and the lower multi-step legs (3) are above the fourth step.Repeat the steps above in order to go up the stairs, and when going down, do the opposite. be.

Even if an adult carries me like this, I can still go up and down the stairs with my own knife.
