Claims

[Scope of Claim for Utility Model Registration] A base that forms a tipping lever for tilting that is fixed to the lower side of the vehicle body in each of the vehicle body mechanisms 1 on both the left and right sides of a handheld wheelchair that is placed in a horizontal state.・Pipe 2
The rear end portion 3 is extended upward to the rear portion on the same vertical plane, and is approximately located at an intersection position 8 where the rear outer circumference 5 of the drive wheel 4 intersects with the axial horizontal plane 7 of the axle 6. At a spatial position 9 in the extension direction similar to this intersection position 8, a vertical rod 10 is formed which is bent vertically with respect to the upper direction, and the upper end side of the vertical rod 10 is further bent at an appropriate length. The rod end 11 is fixed to the back pipe 12 of the vehicle body by extending in a curved shape, and the vertical rod 1 is also fixed to the back pipe 12 of the vehicle body.
0, a plurality of independently rotating small wheels 13 are attached in series, and this structure is assembled symmetrically. , an auxiliary device for wheelchairs to ascend and descend stairs. Embodiment (1) The shape of the vertical rod 10 in the above text is not only a vertical linear shape, but also formed into a vertically erect circular arc shape with the spatial position 9 as the lower end. A device to assist wheelchairs in going up and down stairs. Embodiment (2) In the above text, the rear end 3 of the base pipe 2 is extended to form a vertical rod 10 in the middle, and the upper end thereof is further extended in a curved shape to form the back pipe of the vehicle body. In addition to configuring the entire length of the rod until it is fixed to - as a single unit, the vertical rod 10 and the rods continuous to the upper and lower ends are divided into a plurality of parts and connected, thereby carrying out the procedure described in the text. , an auxiliary device for wheelchairs to ascend and descend stairs.
