ABSTRACT:
A drawer system with an improved drawer interlock mechanism has a frame which slidably supports at least one drawer and at least one column of locking bars, perpendicular to the movement of the drawer. Each drawer includes a cam associated with a set of cam followers disposed on facing ends of adjacent locking bars. Each drawer cam is normally aligned to separate its associated set of cam followers and the associated locking bars when the drawer is opened, thereby displacing all locking bars in the column. The displaced locking bars misalign the cam followers associated with unopened drawers thereby preventing them from opening. Bias means returns the column of locking bars to a normal rest position when the drawer is retracted. A locking cam can be actuated to displace all locking bars toward said bias means to prevent all drawers from opening. Separate interlocking mechanisms can be located adjacent diagonal corners of the frame so that drawers can be interchangeably oriented to operate from one of two faces in an independent fashion.
