PROBLEM TO BE SOLVED: To provide a body weight supporting device that facilitates a posture of a power position necessary for preventing low back pain and a return from this posture in a simple configuration.SOLUTION: A body weight supporting device 1 is provided for assisting a posture of a worker in a half sitting. The body weight supporting device comprises: a shoe sole part 2 for placing a foot a pair of connections 3a, 3b extending from both sides of this shoe sole part 2 a turning shin receiving unit 5 mounted through connecting shafts 4a, 4b provided in the ends of these connections 3a, 3b spring members 6a, 6b for biasing this shin receiving part 5 in the plantar flexion direction and stopper mechanisms 7a, 7b for stopping the shin receiving part 5 turned by a shin dorsiflexion action in a desired dorsiflexion angle against the biasing force of this spring members 6a, 6b. The spring members 6a, 6b is accumulated by the shin dorsiflexion action and is mounted in the connecting shafts 4a, 4b in order to provide rotational force in the plantar flexion direction to the shin receiving part 5.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】 簡易な構成で、腰痛予防に必要なパワーポジションの姿勢とこの姿勢からの復帰が容易な体重支持装置を提供する。【解決手段】 作業者の中腰姿勢などを補助する体重支持装置1であって、足を載せる靴底部2と、この靴底部2の両側から延設する一対の連結部3a,3bと、これらの連結部3a,3bの端部に設けた連結軸部4a,4bを介して取り付けた回動自在な脛受け部5と、この脛受け部5を底屈方向に付勢するバネ部材6a,6bと、このバネ部材6a,6bの付勢力に抗して脛の背屈動作により回動する脛受け部5を所望な背屈角度で停止させるストッパ機構7a,7bからなる。バネ部材6a,6bは、脛の背屈動作により蓄勢され、脛受け部5に底屈方向の回転力を与えるべく連結軸部4a,4bに装着されている。【選択図】 図1
