Disclosed herein is a door lock configured to indicate the lock status of the door lock to nearby persons. In some instances, the door lock includes a locking mechanism with one or more actuators configured to act directly on an indicator such that the indicator indicates the lock status of the lock.

Door lock with indicator

A door lock may include a latch bolt head and a blocking pin. The latch bolt head may be configured to move between an extended position and a retracted position to selectively engage a latch head pocket of a door jamb. The latch bolt head may also be configured to move between a first rotational position and a second rotational position, wherein the blocking pin is configured to prevent movement of the latch bolt head from the first rotational position to the second rotational position when the blocking pin is in an engaged position.

Push through latch

A button assembly for a door lock may include a button and a shank. The button may be toollessly couplable to the shank to allow force transmission between the button and the shank. The button may transfer linear force and torque along a longitudinal axis of the button to the shank to allow a state of an associated lock body to be changed.

Adjustable button mechanism

Disclosed herein are cylindrical door locks configured to indicate the lock status of the door lock to nearby persons. In some instances, the lock status is indicated on a first side of the door. In other instances, the lock status is indicated on both a first side and a second side of the door.

Indicator lock

A tool for adjusting the backset of a latch bolt. The latch bolt includes a latch bolt and a tailpiece. A housing receives the latch bolt and includes a transversely extending protrusion. A casing slidably receives the housing such that the protrusion on the housing is received in a slot on the casing and an inner end of the tailpiece extends from the housing and casing. The casing is rotated relative to the housing to allow relative axial movement between the casing and the housing when transitioning between the first backset position and the second backset position. The tool includes a member defining a first slot for receiving the inner end of the tailpiece and a pair of second slots for receiving the pair of ears such that rotation of the tool rotates the tailpiece and the casing simultaneously.

Tool for use with adjustable backset latch

A progressive deadlatching arrangement for a deadbolt lock prevents an external force applied on the deadbolt from retracting the deadbolt or otherwise compromising a secured door. The progressive deadlatching arrangement prevents external forces from retracting the deadbolt while still allowing an authorized user to operate the deadbolt. ASSA ABLOY Residential Group, Inc. is a subsidiary of ASSA ABLOY AB.

Progressive deadlatching for deadbolts

A latch assembly comprises a latch bolt and a tailpiece including a first tailpiece member mounted to the latch bolt and a second tailpiece member. The second tailpiece member is movably received in a bore of the first tailpiece member and operably connected to a latch operator. The second tailpiece member is received in one of two axially spaced recesses in the bore in a first backset position and a second backset position. Relative axial movement between the first tailpiece member and the second tailpiece member is prevented in a first relative rotational position in the first backset position and in a second relative rotational position in the second backset position, and relative axial movement is allowed in a third relative rotational position to allow the second tailpiece member to be moved between the first backset position and the second backset position. A housing slidably receives the latch bolt therein and a casing defining a peripheral slot having two axially spaced circumferential portions interconnected by a longitudinal portion receives the housing such that a protrusion on the housing is slidably received in the slot. Relative axial movement between the casing and the housing is prevented when the protrusion is in either one of the two circumferential portions of the slot in a first rotational position in the first backset position and in a second rotational position in the second backset position, and relative axial movement is allowed in a third rotational position to allow the protrusion on the housing to be movable along the longitudinal passage between the circumferential portions of the slot when transitioning between the first backset position and the second backset position.

Adjustable backset cylindrical latch

An interconnected lock for use on a door, where the lock has adjustable offset spacing between a deadbolt and latchbolt. The lock includes first and second shafts for actuating the deadbolt lock mechanism, at different offset spacings. A linkage arm connected to and moveable by the latchbolt actuator is alternately connectable to rotate either the first or second deadbolt-actuating shaft. The linkage arm has first and second upper positions, for alternate connection to rotate the first and second deadbolt-actuating shafts, respectively. Upon operation of the interior actuator, the linkage arm moves 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.

Interconnected lock with direct drive for adjustable deadbolt to latchbolt spacing

A lock cylinder monitoring assembly for monitoring position of a lock cylinder. The monitoring assembly includes a housing having an inner cavity and an exterior diameter. The exterior diameter of the housing is not significantly greater than the corresponding cylinder diameter. The assembly further includes a switch received into the inner cavity of the housing. The switch is in electrical communication with an indicator. The switch is reactive to any change in position of the lock cylinder.
