ABSTRACT:
A file cabinet (10) including slidably mounted drawers (18) is provided with an interlock mechanism which prevents the simultaneous opening of two drawers. The interlock mechanism includes an elongate channel (24) having a fixed length and depth. Slidable within the channel (24) along the length thereof are blocks (42) and wedges (44). The blocks (44) include at least one end surface (48) which is at an acute angle relative to the bottom wall (28) of the channel (24). The wedge members (44) are displaceable relatively into and out of the depth of the channel. The wedge members have surfaces (52) complementary to and in sliding contact with the end surfaces (48) of the blocks. The length of the channel (28) is less than that of the combined length of all of the block (42) and wedge members (44) disposed therein and at least as long as the combined length of the block and one of the wedge members. A cam means and actuator therefor (55) is mounted on the cabinet so as to displace the wedge members (44) into and out of the channel. When one drawer is opened, the actuator (58) displaces the cam (56) so as to force one of the wedge members (44) into the channel. Displacement of the wedge member (44) causes sliding movement between the blocks (42) and wedge members (44) to a position where the combined length of the blocks and wedge members is equal to the length of the channel (24). In this way, a second drawer cannot be opened since there is no room for further relative movement of the blocks and wedge members.
