PROBLEM TO BE SOLVED: To provide a handcart which allows a user to lift the front wheel of the handcart from the ground with only a few operations and to easily make the handcart climb over a step without excessively relying on the arm strength of the user.SOLUTION: A handcart 1 includes: a front block 2a and a rear block 2b which are connected by a connection part 5 so that they can be bent within the vertical plane. The front block 2a is provided with a front wheel 3, and the rear block 2b is provided with a rear wheel 4 and a handle 6. The connection part 5 is provided with an auxiliary wheel 7. The connection part 5 is also provide with a lock device 9 for locking the front block 2a and the rear block 2b in a position in which the front wheel 3 and the rear wheel 4 touch the ground and the auxiliary wheel 7 is lifted from the ground. When the lock device 9 releases the locking, the front block 2a and the rear block 2b are bent, which makes it possible to change the position into a position in which the auxiliary wheel 7 touches the ground and the front wheel 3 is lifted from the ground.COPYRIGHT: (C)2016,JPO&INPIT【課題】数少ない操作で前輪を浮かせることができ、腕力に過度に依存することなく段差乗り越えの容易化を達成できる手押し車を提供する。【解決手段】手押し車1は、連結部5により垂直面内で折れ曲がり可能に連結された前部ブロック2a及び後部ブロック2bを備える。前部ブロック2aには前輪3が設けられ、後部ブロック2bには後輪4及びハンドル6が設けられる。連結部5には補助輪7が設けられる。また、前部ブロック2aと後部ブロック2bを、前輪3と後輪4が接地し補助輪7が浮上する姿勢に固定するロック装置9を備える。ロック装置9のロック解除時に前部ブロック2aと後部ブロック2bが折れ曲がることで、補助輪7が接地し前輪3が浮上する状態に姿勢変換可能である。【選択図】図2
