Abstract:
PROBLEM TO BE SOLVED: To prevent all drawers from being pulled out at the time of earthquake by respectively providing an upper key plate, lower key plate and first and second cams at positions corresponding to each of drawers, and turning the first cam when one of the drawers is pulled out.

To the first cam 6 a plate 8 is fixed so as to be turnable. A guide 10 is engaged with an upper part of the upper key plate 4 and a spacer 11 is provided so as to form a space 16 with respect to a top plate 15. As for the drawers 1 on the second stage or subsequent stage, the lower key plate 5 corresponds to the upper key plate 4, and the first cam 6 and the second cam 7 are installed in order successively, both of them being connected by means of an operation rod 13. When the drawer 1 is pulled out, an operation piece 14 pushes up the first can 6, then the plate 8 is turned around a fixing shaft to raise the key plate 4, guide 10 and the spacer 11, thereby performing locking. Accordingly, two or more drawers can not be pulled out simultaneously.
