ABSTRACT:
A lock for cabinets wherein a lock component is attached to one element of the cabinet and a counter-locking component is attached to another element. The lock component includes a hook-shaped latching bolt which is slidable and swivelable to become engaged with and disengaged from the counter-locking component. The latching bolt is held in a latching position by a locking bolt part of a permutation lock, and also by a retaining mechanism in the form of a heart-shaped endless cam slot which effects a release of the latching bolt only in response to a displacement of the latter in a door-closing direction.
