Description

  The present invention is not limited to hand and foot, and when trying to recover and improve motor function by rehabilitation, not only care treatment performed at hospitals and care facilities, but also staying at the facility when returning home. For example, the present invention relates to a care vehicle that can easily improve the rehabilitation and motor functions of a cared person when riding in a care vehicle in a living room.

  In the conventional prior art, Japanese Patent Laid-Open No. 2011-115522 moves a wheelchair by self-propelling, and in handling, if long-running or climbing is limited by the power of the arm, the handling can be turned with the foot. Such a traveling wheelchair. Japanese Patent Application Laid-Open No. 2000-14710 discloses a wheelchair that can prevent a decrease in leg function and reduce labor burden by rehabilitation, and can recover a decreased function of the leg at an early stage.

  However, in the above prior art, the former is intended to run as a wheelchair, and for that purpose, run by handling, or rotate the handle with the foot to move the care vehicle, and improve the exercise ability of the hand and foot However, the exercise ability to move the own weight sitting on the nursing chair by one's own power must be considerably improved, and the previous problems remain.

  In the latter case, the purpose is to improve the exercise ability of the leg with the electric car, and while the car is moved electrically, the electric movement is the same as the exercise of the parallel movement of the legs with the crank rod. Although it seems that it is possible to exercise the legs with a forced rotation pedal, it can be judged that the legs have been moved on their own, but it is not possible to measure the ability to move the nursing car that they are sitting on with their own legs. There is a disadvantage that it is possible.
