Deadbolt assembly having selectable backset distance

Claim 1

a deadbolt lockset having a selectable backset distance comprising: a hollow latch case assembly; a deadbolt slidably carried within the latch case assembly and movable between an extended and a retracted position; actuator means for extending and retracting the deadbolt; a deadbolt extension slidably carried within the latch case assembly and coupled at one end to the deadbolt, the other end of the deadbolt extension including first and second spaced openings, the second opening being spaced between the first opening and the deadbolt; coupling means, connected to the actuator means, for coupling the actuator means to the deadbolt extension, the coupling means being selectively coupleable to the deadbolt extension at either of the spaced openings by moving the coupling means and being slidable within the latch case during selective coupling from a first location within the latch case, where the coupling means is coupled to the first deadbolt extension opening thereby to provide a first backset distance, to a second location within the latch case where the coupling means is coupled to the second deadbolt extension opening thereby to provide a second backset distance; and adjustment means for guiding movement of the coupling means in selecting backset distance from the first location to the second location, wherein at each of the first and second locations the actuator means is operable to extend or retract the deadbolt.
