Abstract: The present disclosure generally relates to a lock including a blocker (e.g., a bolt) useable to selectively prevent access through a portal such as a door. The blocker can be retained in a blocking position to prevent access through the portal by a retainer. In alternative embodiments, the blocker can also be retained in an open position to allow access through the portal. A retainer can be utilized to retain the blocker in the blocking position preventing access through the portal and can also be utilized, in certain embodiments, to retain the blocker in the open position to allow access through the portal. A retainer blocker can be utilized to maintain the retainer in position to retain the blocker (e.g., bolt) in a fixed position. An actuator may, in certain alternative embodiments, be employed to position the retainer blocker. In certain embodiments, the actuator is controlled by an electronic controller.

The lock indicators include a second cuff for receiving input from the first cuff via a transmission rod causing the second cuff to transition from a first position to a second position associated with the locked state and the unlocked state.

Abstract: A cylindrical door lock including a latch bolt, a cam assembly operable to move the latch bolt from a first position to a second position, a support at least partially surrounding the cam assembly, an operator actuatable input device operatively coupled to the latch bolt through the cam assembly, a retainer coupling the operator actuatable input device to the support and being moveable between a hold position and a remove position, a removable lock core positioned at least partially within the operator actuatable input device, a throw member operatively coupled with the lock core and the cam assembly to actuate the cam assembly based on a position of the operator actuatable input device, and a stabilizer positioned at least partially within the support and posterior to the lock core.

Abstract: Lock indicators useable to signal the locked or unlocked state of one side of a cylindrical lock across the door selectively secured by the lock. For example, the present disclosure provides a cylindrical lock having an entry function with an indicator viewable by occupants of an area secured by the cylindrical lock. The lock indicators are magnetically driven.

Abstract: Lock indicators useable to signal the locked or unlocked state of a lock at both sides of a door selectively secured by the lock. For example, the present disclosure provides locks having an entry function or an intruder function with an indicator viewable by occupants of an area secured by the lock. In another example, the present disclosure provides a lock having a privacy function with an indicator viewable from external of an area secured by the lock.

Abstract: A door handle set includes a handle assembly having a primary lock and having a handle rotatable about a primary rotational axis. A latch bolt assembly has a latch bolt. The latch bolt assembly is operatively coupled to the handle assembly, wherein a rotation of the handle results in a linear translation of the latch bolt. A supplemental lock has a second axis parallel to, and spaced apart from, the primary rotational axis. The supplemental lock has an actuator that is operable relative to the second axis. The supplemental lock is configured to selectively block the rotation of the handle regardless of the locking state of the primary lock.

Abstract: A small angle latch is disclosed which moves a latch bolt from a fully extended position to a retracted position wherein the latch bolt is substantially flush with an outer surface of a faceplate through a rotation of an input device, such as a lever, in the range of from about 25 degrees to about 35 degrees, without exceeding a maximum torque upon the input member of 28 inch-pounds.
