Abstract

PROBLEM TO BE SOLVED: To simply climb over an obstacle through the use of an auxiliary wheel as a slope through the obstacle such as the level difference of a road by fixing the slanted roller-type auxiliary wheel integrated with a wheel to a baby carriage, a wheel chair or the like. SOLUTION: In the case of applying for a wheel chair, the auxiliary wheel constituted by arranging rubber rollers 2 in the state of a plane and freely rotatably connecting the respective rollers 2 is slantingly fixed to a metallic pipe or a wheel supporter 3. This slant angle is within the safety standard of the wheel chair and the type of the rollers 2 is made at a distance equal to or shorter than a distance of the outer most side of a wheel 1 with the supporter 3 as a center. By integrating the slanted roller-type auxiliary wheel with the wheel 1 like this, the auxiliary wheel plats the role of a slope to simply climb over the obstacle 4 through the obstacle 4 such as level difference exists.

に対し直角に向く構造となっている。[0001] The present invention relates to a roller-type auxiliary wheel having an inclined front wheel for a wheelchair, and a front wheel for a baby carriage or the like.
Attach to the rear wheel. The auxiliary wheels serve as a slope for obstacles such as steps on a road, and can overcome obstacles. In addition, since the present invention is integrated with the wheels, the auxiliary wheels are always oriented at right angles to the direction in which they move forward.

It was possible to get over with. This will be described with reference to the drawings. The rubber rollers 2 are arranged in a plate shape, and the rubber rollers 2 are connected so that they can rotate freely, and the wheel support 3 is inclined with a metal pipe or a metal plate. And attach it. At this time, the inclination angle is set within a safety standard for a wheelchair or a baby carriage, and the tip of the rubber roller portion is set to be equal to or less than the outermost distance of the wheel 1 centering on the wheel support 3.
