ABSTRACT:
A deadbolt assembly of the kind in which a deadbolt is mounted on a housing for linear movement between inoperative and inoperative positions in which the deadbolt engages with and does not engage respectively, a strike. An actuator is rotatably mounted on the housing and is drivably connected to the actuator through a drive plate which rotates in response to operation of the actuator, and a drive pin is secured to the plate at a position radially outwards of the rotational axis of the plate. The pin locates within a non-circular hole provided in the deadbolt and reacts against edges of that hole to cause the deadbolt movement. The pin moves along an arcuate path between each of its two extreme positions, and at each of those positions the pin lies on a straight line which extends substantially parallel to the direction of movement of the deadbolt and which substantially intersects the rotational axis of the drive plate. Both the deadbolt and the strike can be made from steel or other strong metal.
