INTERCONNECTED LOCK WITH ADJUSTABLE DEADBOLT TO LATCHBOLT SPACING

摘要

An interconnected lock has adjustable offset spacing between latchbolt and deadbolt lock mechanisms, and a sliding pusher mechanism therebetween. The pusher mechanism is operable upon operation of an interior actuator to bear against the deadbolt lock mechanism and move the deadbolt along the second axis from the latched to the unlatched position at the same time that the operation of the interior actuator moves the latchbolt along the first axis from the latched to the unlatched position. The pusher mechanism includes an arm that bears against the deadbolt lock mechanism and may be retracted and extended between a first length and a second, longer length when changing offset spacing between the deadbolt and latchbolt. The arm is extendable from the first length to the second length without adding or removing any components thereof.

1. An interconnected lock for use on a door, the lock having adjustable offset spacing between a deadbolt and latchbolt, comprising:
a latchbolt mechanism mountable in a first bore through a door, the latchbolt lock mechanism including a latchbolt and an interior actuator operable to move the latchbolt between latched and unlatched positions along a first axis; a deadbolt lock mechanism mountable in a second bore through a door, the second bore being spaced from the first bore, the deadbolt lock mechanism including a deadbolt moveable by the deadbolt lock mechanism along a second axis between latched and unlatched positions, distance between the latchbolt first axis and the deadbolt second axis being the offset spacing; a sliding pusher mechanism between the latchbolt mechanism and the deadbolt lock mechanism, the pusher mechanism operable upon operation of the interior actuator to bear against the deadbolt lock mechanism and move the deadbolt along the second axis from the latched to the unlatched position at the same time that the operation of the interior actuator moves the latchbolt along the first axis from the latched to the unlatched position, the pusher mechanism being extendable between a first length and a second, longer length when adjusting spacing between the first and second axes to change offset spacing between the deadbolt and latchbolt between a first distance and a second, longer distance.
