ABSTRACT:
A self-locking lock assembly for a cabinet or locker door includes a rotary operating member (25) having a head (26) adapted to be operated from the exterior of the door, and an inner bolt (31) provided with a rib (36) inclined with respect to the axis of said operating member so that its cooperation with a flange (14) of a door opening (3) causes it to rotate while compressing a return spring (41) whenever the door is manually pushed. The lock assembly can advantageously be used in cabinets or lockers the doors of which must be opened only by safety personnel, but may be closed by maintenance personnel.
