Description

  The present invention is applicable when the user of the wheelchair is an elderly person or the like who is remarkably shorter than usual and cannot reach the footrest provided on the wheelchair or when the foot reaches the footrest provided on the wheelchair. However, the present invention relates to a footrest for a wheelchair that can be mounted on a footrest of a wheelchair and placed on a higher position than the footrest when the footrest is not high enough and a stable posture is difficult.

  Conventionally, a commercially available wheelchair is equipped with a footrest for placing a foot of a wheelchair user on the lower front portion thereof. This footrest is used by a user seated in a wheelchair as a table on which the foot is placed. By placing the foot on a footrest with an appropriate height, the footrest takes a stable posture when seated on the wheelchair. be able to.

  As the footrest, for example, a wheelchair described in Japanese Patent Application Laid-Open No. 2004-121723, there is a footrest that is used by being tilted in the inner horizontal direction facing the lower front ends of the left and right frames via pins. In addition, there is a wheelchair described in Japanese Patent Application Laid-Open No. 2003-334216 in which a wide footrest is provided to protrude forward between the front ends of the left and right frames. Each of the footrests is for placing a foot in order to stabilize the posture when sitting on a wheelchair. Usually, in a general-purpose product, the seat is based on the physique of a general adult male. The height from the footrest to the footrest is determined.

  For this reason, as mentioned above, in the case of an elderly person or the like who is significantly shorter than usual, the footrest does not reach when sitting on the wheelchair and the posture is sitting on the wheelchair for a long time. This causes inconveniences such as fatigue of the body and difficulty in changing posture because the feet cannot be stepped on even if the posture is changed. Further, even when the foot reaches the footrest, the same inconvenience occurs even when the height of the footrest is not sufficient.

  In these cases, some wheelchairs are equipped with a mechanism for adjusting the height of the footrest.However, since a tool such as a screwdriver or hex wrench is required to adjust the height, the wheelchair must be owned by an individual. However, in a wheelchair that is used for general purposes and who does not know when to use it, it is complicated and difficult to adjust the height using these tools each time. Moreover, even if the wheelchair is equipped with these height adjustment mechanisms and the footrest position is set at the highest position, even if the footrest still does not reach the footrest or the footrest reaches the footrest In some cases, sufficient height cannot be maintained.

  For this reason, it is desired to provide a platform on which the foot can be placed further upward than the setting position of the footrest of the wheelchair.

  On the other hand, as a technique for attaching a base for placing a foot on a footrest of a wheelchair, for example, a footrest for a wheelchair described in JP-A-2004-97457 is known. The footrest for a wheelchair described in the Japanese Patent Application Laid-Open No. 2004-97457 is a wheelchair in order to allow a care recipient who has an achilles tendon to shrink and a toe straight due to bedridden to move normally on a wheelchair. The foot insertion part which made the insertion direction diagonally forward and downward was attached to the footrest part provided in the right and left of the front part.
