ABSTRACT:
The invention refers to an unlocking and expelling mechanism for a drawer in a cabinet or a frame, preferably in cash registers, wherein a lock stud is secured to the back end of the drawer and is engaged, when the drawer is pushed in against a spring force, by a locking hook mounted on a pivot shaft rotatably supported in a fixed bracket. The shaft has a lateral projection for blocking a slidable latch which can be retracted from the projection by manually operating an electromagnet, so that the shaft will be free to rotate the hook to release the stud and allow expelling of the drawer. The improvement consists in providing a movable and guided connection between the hook and the pivot shaft so as to, when the shaft begins to rotate, the hook is imparted a reciprocating movement in its longitudinal direction. The hook has an aperture having a guiding edge for cooperation with a lifting pin fixed in the cabinet, said edge being inclined for lifting the hook in its forwards stroke caused by said shaft.
