PROBLEM TO BE SOLVED: To provide a walking aid that becomes compact not only longitudinally but also vertically in a storage state, and is capable of being changed from the storage state to the usable state or conversely changed by an easy operation without performing a complicated operation.SOLUTION: A pair of supporting columns 8 extending vertically are provided respectively in a pair of side frames 4. Each of the pair of supporting columns 8 is made to comprise an inside cylindrical part 10 and an outside cylindrical part 12 having an equal length. Each of the pair of supporting columns 8 is made extensible between an extended state where most of the inside cylindrical part 10 is exposed and a retraction state where most of the inside cylindrical part 10 is stored in the outside cylindrical part 12. Further, an engagement piece arranged in each of the pair of supporting columns 8 is biased by biasing means, and action pieces acting on these engagement pieces are connected by a connecting member to be simultaneously operated.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】収納状態にあっては前後方向だけでなく上下方向にもコンパクトになり、且つ煩雑な操作をすることなく容易な操作で収納状態から使用可能状態へ又はその逆に変化させることが可能な歩行補助器を提供すること。【解決手段】一対の側方フレーム4の各々に上下方向に延びる一対の支持柱8を設け、一対の支持柱8の各々が相互に同等の長さを有する内側筒部10及び外側筒部12を含むようにし、一対の支持柱8の各々を、内側筒部10の大部分が露出された伸長状態と内側筒部10の大部分が外側筒部12に収納された退縮状態との間で伸縮自在となるようにすると共に、一対の支持柱8の各々に配設された係合片を付勢手段によって付勢し且つこれらの係合片に作用する作用片を連結部材で接続して同時に作動させる。【選択図】図1
