Patent ID: 7363784

Claim:
An independently interactive interconnected lock comprising: a latchbolt lock mechanism mountable in a first bore through a door, the latchbolt lock mechanism including a latchbolt and an outer handle, the latchbolt lock mechanism being operable by the outer handle to move the latchbolt between latched and unlatched positions; a deadbolt lock mechanism mountable in a second bore through the door offset from the first bore, the deadbolt lock mechanism including a deadbolt movable by the deadbolt lock mechanism between bolted and unbolted positions; and an interconnecting mechanism connected between the latchbolt lock mechanism and the deadbolt lock mechanism to drive the latchbolt between the latched and unlatched positions and drive the deadbolt between the bolted and unbolted positions, the interconnecting mechanism being operable by an inner handle movable between an up position, an intermediate position and a down position; the interconnecting mechanism driving the deadbolt to the bolted position when the inner handle is moved to the up position to place the deadbolt in the bolted position when the inner handle is moved to the up position; the interconnecting mechanism driving the deadbolt to the unbolted position when the inner handle is moved to the intermediate position to place the deadbolt in the unbolted position when the inner handle is moved to the intermediate position; and the interconnecting mechanism driving the latchbolt to the unlatched position when the inner handle is moved to the down position to place the latchbolt in the unlatched position when the inner handle is moved to the down position.
