DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheelchair, and more particularly, to a footrest provided at a front portion of a wheelchair.

[0002]

2. Description of the Related Art A footrest for a wheelchair user to put his / her feet on is a simple type in which a synthetic fiber cloth is passed over the legs of the left and right front frames. Various designs have been devised, such as those provided with a tread plate that can jump up. However, the simple type in which the synthetic fiber cloth is passed between the left and right legs has a drawback in that when the foot is put on the foot, the foot cannot be stepped on. In addition, the footrest that makes the synthetic resin plate out from the left and right sides of the front frame and is used as a footrest is harder and more stable than fabric when putting feet on, but when folded when not in use, There is a problem in that the synthetic resin footrest must be flipped up by hands or feet outwardly of the left and right front frames.

Furthermore, the fact that the footrest is always flat, irrespective of the physical condition of the wheelchair user,
In many cases, the user is forced to use an unreasonable posture,
May not be able to withstand prolonged use.

[0004] Thus, for a person using a wheelchair,
There is a demand for an easy-to-handle wheelchair that has a footrest on a footrest, has a sense of stability, does not get tired even when used for a long time, and has a footrest structure that can be easily folded when not in use.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a wheelchair having a footrest which has a sense of stability even when the user puts his / her foot during use and which is easily folded when not in use.

Means for Solving the Problems As a result of intensive studies to solve the above problems, a wheelchair having a backrest, a seat and a footrest becomes flat when the foot is placed on the footplate of the footrest. As described above, when the foot is not placed on the wheelchair, the wheelchair has a stable shape and can be easily folded.

A first feature of the wheelchair of the present invention is that the wheelchair has a backrest, a footrest on which a foot plate is mounted on a footrest support supported by a seat and left and right front frames via a footrest support supporting member. In the wheelchair, a spring member is inserted into a connection portion between the left and right footrest supports.

[0008] Further, the wheelchair is characterized in that the footrest is arranged in a mountain shape by a spring member inserted into a connecting portion between the left and right footrest supports. A spring member is inserted into the connecting portion between the left and right footrest supports, and the footrest is formed to have a mountain shape, so that the footrest becomes flat when placed on the footrest, giving a sense of stability. In a state where the foot is not placed, the left and right foot plates are formed in a mountain shape, so that when folded, the footrest support can be easily folded without resistance.

A second feature of the present invention is that the angle of the foot plate of the footrest is adjustable. By attaching the angle adjusting member to the footrest support portion of the footrest, the angle of the footplate can be adjusted, and the angle of the footplate can be adjusted according to the condition of the user's body. As a result, the foot can be put on the foot plate in a natural posture, and the foot can be put on without being tired.

A third feature of the present invention is that a rubber plate is attached to a foot plate of a footrest. When the foot is placed on the foot plate by attaching a rubber plate to a synthetic resin or metal foot plate, the foot is placed softer and for a longer time compared to a hard synthetic resin or metal foot plate. It doesn't hurt even if you do it, and there is a sense of stability without your foot slipping from the foot plate.
