である。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rubber tire in which a front wheel of a wheelchair can move up and down.
【０００２】[0002]
【従来の技術】従来の、車椅子の前輪は、１ｃｍ程の段
があっても、走行がしにくく又、介護人にも、余分な動
力が要りました。2. Description of the Related Art Conventionally, the front wheel of a wheelchair is difficult to travel even if there is a step of about 1 cm, and also a caregiver needs extra power.
【０００３】[0003]
【発明が解決しようとする課題】本発明は、その欠点を
なくすために、車椅子の前輪の直径が、小さなタイヤで

障が無い。DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to carry out the present invention, a set of rubber tires composed of rubber tires (10) and (11) is first manufactured. This set of rubber tires has a rubber tire in the middle, and a rubber tire on both sides.
▼ A smaller diameter. Three sets of this rubber tire are attached to a metal fitting, and a curable rubber belt with a hole (12) is wound along the middle rubber tire portion, so that the claws do not slip into the hole (12) and are united without slipping. There is no gap between them and smooth running is possible. When the rubber tire moves up and down around the shaft in the hardware, and the rubber tire rises, the rubber tire pushes the running surface, and a slight step can be run smoothly in the manner of leverage. Normal running is carried out by a spring and the rubber tires are kept at an average and only the middle rubber tire is used.
