PROBLEM TO BE SOLVED: To provide one completed lock actuation mechanism capable of simultaneously locking/unlocking all casters with locks.SOLUTION: The lock actuation mechanism includes two parallel frame members 10, a shaft member 15, an operation member 17 provided at one end of the shaft member 15, and a vertically movable member 19 fixing operation rods 51 extending upward from the support shafts 60 of casters 50 with locks arranged at both ends of the frame members 10 at both end parts thereof and vertically movable. The shaft member 15 is provided so as to penetrate both side faces 11 for forming the groove part 13 of the frame member 10 and rotated below the vertically movable member 19. An eccentric cam member 25 is provided in the portion of the shaft member 15 penetrating the groove part 13 of the frame member 10. When the operation member 17 is rotated in one direction, both vertically movable members 19 move downward to lock all the casters, and when the operation member 17 is reversely rotated, the locking of all the casters is released.SELECTED DRAWING: Figure 3
【課題】全ロック付きキャスターを同時にロックし且つアンロックでき、一つの完結したロック作動機構を提供する。【解決手段】平行な2本の枠部材10と、軸部材15と、この軸部材15の一端に設けた操作部材17と、枠部材10の両端部に配設されるロック付きキャスター50の支軸60から上方に延長する作動杆51をその両端部分で固定し、上下に移動可能な上下可動部材19とから成る。軸部材15は枠部材10の溝条部13を形成する両側面11を貫通し且つ上下可動部材19の下方で回動自在に設ける。枠部材10の溝条部13を貫通する軸部材15の部位に偏心カム部材25を設ける。操作部材17を一方向に回動させると、両上下可動部材19が下方に移動して全キャスターがロックされ、操作部材17を逆方向に回動させると、全キャスターのロックが解除される【選択図】図3
