ABSTRACT:
A push lever activated dead-bolt lock for a door is described. The dead-bolt lock includes a dead-bolt axially mounted within a sleeve, the sleeve having a slot formed in each lateral side of the sleeve, the slots aligned parallel to each other and having a horizontal section and a vertical section; a cross member mounted within the dead-bolt in a position so that a first end and a second end of the cross member protrude through each slot; a spring mounted between the dead-bolt and the back wall of the sleeve; and an activator lever mounted so that one end of the activator lever contacts the first end of the cross member and the other end of the activator lever protrudes through to the exterior of the door, the activator lever oriented that movement of the lever by user moves the cross member from a position in a vertical section of the slot to a position in a horizontal section of the slot, the movement of the cross member releasing tension on the spring, the spring propelling the dead-bolt into a locked position. The lock is unlocked by returning the cross member to a vertical section of the T-shaped slot using a key. The key is inserted into a key acceptor, the key acceptor including an arm which contacts the first end of the cross member and is oriented such that when the key is turned, the arm propels cross member along horizontal section of the slot and into a vertical section of the slot, the first end of the cross member resting against the end of the activator lever opposite the end of the activator lever that protrudes to the exterior of the door. Thus, the user can activate the lock by simply pushing the activator lever.
