Description

[0001]
BACKGROUND OF THE INVENTION
More particularly, the present invention relates to a footrest provided at the front of the wheelchair.
[0002]
[Prior art]
The footrest for the wheelchair user to place his / her foot on is a simple type in which a synthetic fiber cloth is passed over the legs of the left and right front frames. Various things have been devised, such as those with a tread that can be done. However, the simple type in which a synthetic fiber cloth is passed to the left and right leg portions has a drawback that the foot does not stand tight when the foot is placed. In addition, the footrest that takes the synthetic resin plate from the left and right sides of the front frame and uses it as a footrest is harder and more stable when the foot is placed, but it folds when not in use. There is a problem in that the footrest made of synthetic resin must be flipped up by hand or foot in the outward direction of the left and right front frames.
[0003]
Furthermore, the fact that the footrest is always flat regardless of the state of the body of the wheelchair user often imposes an unreasonable posture for the user and may not be able to withstand long-term use.
[0004]
For those who use wheelchairs, the appearance of an easy-to-handle wheelchair with a footrest structure that is stable when placed on the footrest, does not get tired even when used for a long time, and is easy to fold when not in use. It is desired.
[0005]
[Problems to be solved by the invention]
The present invention has been made in view of the above-described facts, and it is an object of the present invention to provide a wheelchair having a footrest that has a sense of stability even when the user puts his / her foot during use and can be folded easily when not in use.
[0006]
[Means for Solving the Problems]
As a result of earnest research to solve the above problems, in a wheelchair having a backrest, a seat part and a footrest, when the foot is placed on the footplate of the footrest, the foot is flattened and the foot is not placed In the case of a mountain shape, we succeeded in developing a wheelchair that is stable and easy to fold.
[0007]
The first feature of the wheelchair of the present invention is a wheelchair having a backrest and a footrest in which a foot plate is mounted on a footrest support supported by a seatrest and left and right front frames via a footrest support support member, A spring member is inserted into the connecting portion between the left and right footrest supports.
[0008]
In addition, 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 in a mountain shape, so that when the foot is placed, the footrest becomes flat and gives a sense of stability. In addition, when the foot is not placed, the left and right foot plates are formed in a mountain shape. As a result, the footrest support can be easily folded without folding.
[0009]
The second feature of the present invention is that the angle of the foot plate of the footrest is adjustable. By attaching an angle adjusting member to the footrest support 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, it is possible to place the foot on the foot plate in a natural posture, and even if the foot is placed for a long time, it does not get tired.
[0010]
The third feature of the present invention is that a rubber plate is attached to the foot plate of the footrest. When a foot is placed on the foot plate by attaching a rubber plate to a synthetic resin or metal foot plate, the foot is softer and longer than a hard synthetic resin or metal foot plate. It doesn't hurt even if it is, and there is a sense of stability without slipping from the foot plate.
