ABSTRACT:
A single key multi locking system for a display case for jewelry and other items to be displayed comprising a housing with transparent flat walls for containing a stand for display. A door hinged along one edge forms one of the walls of the housing. The housing is provided with upper and lower door jambs against which the door is closed. The upper door jamb has a projection spaced away from it a sufficient distance to accomodate the thickness of the door. The lower door jamb is provided with a ledge on the inside of the housing. The door is provided with a lock having a tongue on the inside to raise the door when the tongue is turned down behind the lower jamb and comes in contact with the ledge. With the use of a single lock and key the door is locked top and bottom with a single turn of the key, the upper edge of the door being wedged between the projection and the upper jamb in the locking position. When the door is unlocked the tongue is placed in a horizontal position permitting the door to drop and the tongue is able to clear the lower jamb thereby permitting the door to be opened. Multiple engagement may be provided along both vertical edges of the door.
