A latch bolt with a bolt head that is removably mounted on a latch tail through the use of a reversibility assembly, such as bolt head adjustment mechanism, or the like. The reversibility assembly may comprise one or more locking members (e.g., within the bolt head, the latch tail, tail plate, and/or independent from the other components of the latch bolt) that allow the bolt head and/or the latch tail to be removed, rotated, and reassembled without opening the case of the mortise lock. The bolt head may comprise an anti-friction latch that is configured to pivot within the flanges of the bolt head in a way that maintains contact between the anti-friction lock and the strike plate.

Reversible latchbolt

A hook bolt for a latch assembly includes a hook that deploys laterally from a deadbolt when the deadbolt is moved to an extended position. When the deadbolt is actuated, the hook automatically deploys perpendicular to the deadbolt movement to an engaged position within a corresponding opening in a door jamb to secure the door.

Hook bolt for door lock

A latch bolt with a bolt head that is removably mounted on a latch tail through the use of a bolt head adjustment mechanism. The bolt head adjustment mechanism may comprise one or more locking members (e.g., within the bolt head, the latch tail, and/or independent from the other components of the latch bolt) that allow the bolt head to be removed, rotated, and reassembled while the latch bolt is located within the case of the mortise lock. The bolt head may comprise an anti-friction latch that is configured to pivot within the flanges of the bolt head in a way that maintains contact between the anti-friction lock and the strike plate.

An anti-ligature lock having a locking mechanism for retracting a latch between a locked and an unlocked position. The anti-ligature lock includes a lock handle rotatable about the axis and operatively connected to a lock mechanism hub to rotate the hub and retract the latch between the locked and the unlocked positions. The anti-ligature lock includes a connector between the hub and the lock handle and rotatable about the axis, the connector having a female portion having an opening with walls elongated in a direction normal to the axis and a male portion having projections extending in opposite directions normal to the axis, the male portion extending within the female portion opening and having a neutral position wherein one of the male or female portion may be partially rotated in either direction about the axis with respect to the other of the male or female portion without the male portion projections contacting the female portion opening walls.

Anti-ligature lever

An anti-ligature handle and escutcheon mechanism mountable on a door for operating a lock for securing the door. The mechanism comprises a handle movable between open and closed positions, the handle having a smoothly curved outer surface to prevent the attachment of a ligature thereto and comprising a pivot at a first end for rotating the handle between the open and closed positions to operate the lock. An escutcheon fixed relative to a backing plate is oriented for mounting parallel to the door when the mechanism is mounted on an outer surface of the door, wherein the escutcheon surrounds the handle and defines a recessed area within which the handle pivots. The handle further has a second end including a guide which is trapped beneath and slides along an arcuate edge of the recessed area of the escutcheon to maintain flush contact between a mating surface of the handle and the backing plate to prevent ligatures from being inserted therebetween as the handle rotates to operate the lock. The mechanism further comprises a mounting plate disposed between the backing plate and an inner surface of the door when the mechanism is mounted on the outer surface of the door, the mounting plate fixed relative to the escutcheon and backing plate.
