PROBLEM TO BE SOLVED: To provide a handcart that is excellent in operability and that can be folded safely, easily and compactly even by an elderly person and a physically impaired person.SOLUTION: A small diameter cylinder part 51 of a handle support part is fitted to the large diameter cylinder part 52 in a manner making the small diameter cylinder part 51 slidable, with a handle 41 supported on the upper end, and with a space 53 formed that is continuous in the cylinder axis direction between the lower end side and the large diameter cylinder part 52. In addition, the small diameter cylinder part 51 and the large diameter cylinder part 52 are interlocked to make them vertically movable by pushing and withdrawing the handle 41, making the front wheel frame 1 and rear wheel frame 2 opened and closed. Also, at the position facing the space 53 of the large diameter cylinder part 52, there are vertically provided slide lock pin insertion holes 52c, 52d. When a pin tip end part 65a of the slide lock pin 65 enters the space 53 through either one of the slide lock pin insertion holes 52c, 52d, the front wheel frame 1 and the rear wheel frame 2 can be locked at the open leg position or the closed leg position. In addition, even if the large diameter cylinder part 52 is slide-locked, the small diameter cylinder part 51 is made slidable relative to the large diameter cylinder part 52.COPYRIGHT: (C)2015,JPO&INPIT【課題】操作性がよく、老人や障害を有する人でも安全かつ容易にコンパクトに折り畳むことができる手押し車を提供する。【解決手段】ハンドル支柱部の小径筒部51が、ハンドル41を上端に支持した状態で、下端側を大径筒部52との間に筒軸方向に連続する隙間53を形成した状態で、小径筒部51をスライド可能に大径筒部52に嵌合した。また、ハンドル41を押し引きして小径筒部51および大径筒部52を上下させるに連動し、前輪フレーム1と、後輪フレーム2を開閉できるようにする一方、大径筒部52の隙間53を臨む位置で上下にスライドロックピン挿通孔52c,52dを設け、いずれかのスライドロックピン挿通孔52c、52dを介して隙間53内にスライドロックピン65のピン先端部65aが入り込んだとき、前輪フレーム1と、後輪フレーム2を開脚位置あるいは閉脚位置にロックでき、かつ、大径筒部52がスライドロックされていても小径筒部51を大径筒部52に対してスライド可能にした。【選択図】 図1
