PURPOSE:To simplify the structure of casing locks provided in a storage installation, by providing an actuator for shifting the locks which prevent casings on a shelf from slipping out due to, for example, earthquakes, into its released condition, and as well providing a rod means for locking the actuator, with both actuator and rod means being controlled by a single pusher. CONSTITUTION:When a pusher 39 is moved leftward to be made in contact with the projecting end 26a of a rod 26 in an actuator 23, the rod 26 is moved leftward, overcoming a spring 29. After movement of this rod 26 an operating end projecting piece 39a of the pusher 39 pushes and rotates upward a movable plate 34 in a lock means 31 around a support shaft, overcoming a spring to release a hook part 34a in the movable plate 34 from an engaged recess in the rod 26. Accordingly, the rod 26 is continued to move leftward so that a plate like cam 30 pulls down an arched member 22 or an elevating rod 15 through a follower roller 21, overcoming spring 20. Accordingly, all casing locks 17 are released downward from handles 6b provided to casings 7 which are therefore released from their locked condition. |
