Therefore, a disabled person can freely operate the wheelchair by sitting on the chair (a) and grasping and turning an operation ring (g) having substantially the same diameter as the main wheel (b). But,
In the case of a wheelchair as shown in the figure, since the direction of the auxiliary wheel (c) changes, the traveling direction of the wheelchair can be changed arbitrarily, but when there is a step (obstacle) on the road surface, The small diameter auxiliary wheel (c) cannot get over this step. Not only such a manual wheelchair but also an electric wheelchair equipped with a motor are used. However, even if it is an electric wheelchair, it cannot pass if there is a step on the road surface.

The wheelchair can be freely moved by the main wheel and the auxiliary wheel. In this case, the wheel provided at the tip of the footrest is lifted off the road surface (running surface). If there is a step on the road and the small-diameter auxiliary wheel cannot get over,
If only the wheel of the footrest is positioned over the step and the footrest is lowered in this state, the auxiliary wheel in front of the wheelchair rises. Therefore, if the main wheel is rotated and moved, the auxiliary wheel can get over the step and lower the auxiliary wheel, and the large-diameter main wheel can roll and go over the step.

The footrest shaft 12 employs a worm gear mechanism similarly to the backrest shaft 8. Of course, the invention is not limited to the worm gear mechanism. Further, the tilt angle of the support arm 4 to which the footrest 3 is slidably attached relative to the main body 1 can be adjusted, and in this case also, a worm gear mechanism is used. However, as will be described later, since the support arm 4 must be turned with the handicapped person on the footrest 3, it is necessary to have a strong structure in terms of strength and generate a large torque. Hereinafter, the operation of the wheelchair according to the present invention will be described item by item.

(A) Stepping Over Steps (Obstacles) FIG. 2 is a schematic view showing a case in which the vehicle travels over an obstacle 13. In this case, the auxiliary wheel 6 is lifted and passed. That is, since the auxiliary wheel 6 has a small diameter, it cannot pass over an obstacle 13 having a certain height. However, the footrest 3 is extended downward and the front of the wheelchair is raised as shown in FIG. As an operation procedure of the footrest 3, the support arm 4 is operated to move the base 10 of the footrest 3 to the back of the obstacle 13, and the base 10 is linearly aligned with the slide part 11.
The support arm 4 is raised to press the wheels 14 attached to the base 10 against the road surface, and the auxiliary wheels 6 are lifted.

If the footrest 3 is lifted, the footrest 3 is lifted together with the footrest 3, and then the support arm 4 is turned horizontally. When a person with a disability sits on the footrest 3 and lifts, a heavy motor and a battery are mounted so that the center of gravity shifts forward, but the main wheel 5 does not float. Alternatively, the arm 15 can be made to protrude from the main body 1 so that the auxiliary wheel 6 moves forward. Therefore, when the support arm 4 is substantially horizontal as shown in FIG. 4, the disabled person can move to the chair 2 by holding the handrails 16 provided on both sides of the main body 1. After sitting on the chair 2, the tip of the support arm 4 is lowered as shown in FIG.
