PROBLEM TO BE SOLVED: To provide a wheelchair with a leg exercising mechanism, which allows planterflexion and dorsiflexion exercise of ankle joints to effectively develop blood pumping action by the leg muscles, and is foldable with a simple mechanism.SOLUTION: A wheelchair 10 includes: a pair of main wheels 1a provided on both sides of a seat 11 a free wheel 40a provided in front of each main wheel 1a under the seat 11, the free wheel being rotatable in all directions and a pair of footrests 30a which can be housed on both sides of the forward downside of the seat 11. The wheelchair further includes: a both feet placing means 8 on which both feet can be placed, both ends of both feet placing means 8 being pivotally supported at the forward downside of the seat in such a manner as to be rotatable and attachable/detachable a housing means 32a provided on the front side of the forward downside of the seat 11, the housing means rotatably and detachably holding at least one end of both the ends of both feet placing means 8 and a crank mechanism which converts the rotation of one main wheel 1a to a reciprocating motion. When the one main wheel 1a is rotated by the crank mechanism, the rear end of both feet placing means 8 is vertically moved.COPYRIGHT: (C)2014,JPO&INPIT【課題】足関節の底背屈運動を行うことができ,下肢筋による血液の送り出し作用を効果的に発現させると共に,機構がシンプルであって折り畳みも可能な下肢運動機構付き車椅子を提供する。【解決手段】座部11の両側に一対の主車輪1aを備え,座部11の下部で各主車輪1aの前方に全方向に旋回可能な自在車輪40aを備え,座部11の前方下部両側に収納自在の一対の足台30aを具備した車椅子10であって,両足が乗載可能な両足乗載手段8を有し,該両足乗載手段8の両端部を座部前方下部にて回動自在で且つ着脱自在に軸支すると共に,両足乗載手段8の両端部の少なくとも一の端部を回動自在で着脱自在に保持する収納手段32aを座部11の前方下部手前に備え,一の主車輪1aの回転を往復運動に変換するクランク機構を備え,該クランク機構により前記一の主車輪1aが回転すると両足乗載手段8の後端部が上下動することを特徴とする。【選択図】図1
