ABSTRACT:
Locking devices for kitchen doors, drawers or like closure structures comprise a locking mechanism fixed to the cabinet supporting the door and a key unit mounted on the door. The locking mechanism includes a heart-shaped groove having a recess in which a projecting member in the device lodges under spring bias when the device is in the locked position. Operation of the devices to lock a door is achieved by pushing the door toward the cabinet so the key unit engages the locking mechanism and the projecting member moves in the heart-shaped groove until it lodges in the recess to firmly lock the door. Opening such a locked door is achieved by first pushing the door further closed so that the key unit enters deeper into the locking mechanism to cause the projecting member to disengage from the recess which then allows the door to move forward to an unlocked position. Several embodiments of the devices are disclosed.
