A lockset (10) is actuable by pivoting a lever (14,16) about a longitudinal axis of the lockset (10) by rotating the lever (14,16) and by pivoting the lever (14,16) about an axis transverse to the lockset axis, such as by pushing or pulling. The lockset (10) includes an inside lever (14) and an outside lever (16), each associated with an independent mechanism, each of which can independently actuate the lockset (10). A keyed locking cylinder (250) is disposed axially in the outside lever (16) and pivots with the outside lever (16). The keyed lock cylinder (250) has an opening that pivotably engages an actuator (260). The actuator (260) extends into a retractor assembly (33) of the lockset (10) and is configured to perform an unlocking or locking function when actuated.

A door lock uses a mobile device as an input interface. The door lock includes a latch device mounted to a door, an outer operating device mounted to an outer face of the door, and an inner operating device mounted to an inner face of the door. The outer operating device includes a contact-type connection interface for contact-type connection with the mobile device. After the mobile device is in electrical connection with the outer operating device, an input device of the mobile device is used to input a to-be-identified identification information to the door lock, and the door lock identifies whether the to-be-identified identification information matches authenticated identification information for subsequent unlocking operation or remaining in a locked state.

An apparatus that at least assists in maintaining a lever or knob of a lock device in a relatively neutral and static position. The apparatus includes a biasing element that can be constructed from a compliant material that may at least assist in reducing impact forces between interfacing surfaces at least when the lever or knob is returns to the neutral, static position from one or more activated positions. The compliant nature of the damper can further alleviate issues relating to manufacturing tolerances and wear between interfacing surfaces.

A retention bracket configured for use with a latch mechanism including a laterally extending housing. The retention bracket includes a first wall, a second wall, a collar, and a deformable section. The first and second walls are longitudinally offset from one another and are structured to receive the housing therebetween. The collar extends longitudinally outward from one of the walls and defines an opening having an effective diameter. The deformable section has a natural state in which the effective diameter is a first diameter, and a deformed state in which the effective diameter is a second diameter greater than the first diameter.

A latch assembly that is adjustable between first and second backset settings. A cam is rotatable about a cam axis, and facilitates linear displacement of a latch link in a first direction. A multiplier link is rotatable about a multiplier link axis that is offset from the cam axis can be rotated in the first rotational direction by engagement with the latch link. A latch bar is coupled to the multiplier link and is linearly displaced in a second direction by rotation of the multiplier link in the first direction. The latch apparatus also includes a latch bolt that is coupled to the latch bar, the latch bolt being displaced toward a retracted position by the displacement of the latch bar in the second direction. The latch assembly can also include a dead latch link can block retraction of at least the latch bolt.

A lock for a door including a configurable lock function. The lock includes a removable and user accessible actuator which when removed from the lock disables a lock function, and when inserted into the lock enables the lock function. Removal of the actuator places the lock in a disabled condition in which the lock cannot be locked by other means. Insertion of the actuator into the lock places the lock in an enabled condition in which the lock is locked or unlocked by the position of the actuator. The lock is installed without the actuator when the lock is intended to be used only in a passage operation where the door provides access only, but does not restrict access. The lock is installed with the actuator when the lock is intended to be used in a privacy operation where the lock is intended to restrict access to an area.

A circuit breaker includes an accessory pocket, an accessory cover and a locking device to lock the circuit breaker such that an unauthorized switching of the circuit breaker from OFF to ON or from ON to OFF states is prevented. The locking device includes a first subassembly including a pocket housing. The first subassembly is configured to be installed in the accessory pocket. The locking device further includes a second subassembly including a cylinder lock. The second subassembly is configured to be mounted to the accessory cover. The first subassembly and the second subassembly are configured to self align upon final assembly of the circuit breaker to perform a locking function of the circuit breaker. In this way, the locking device prevents circumvention of a locking feature and selectively provides an ability to lock in an ON state of the circuit breaker.

A retractor assembly for a cylindrical lockset comprises inner and outer retractors. Each of the retractors has a cam engaging surface to convert rotary motion from the inside door handle into linear latch-retracting motion. Inner and outer spindles having retractor activation cams are configured to bear upon cam surfaces of the inner and outer retractors to retract the latch. When the inner door handle is operated, the inner retractor acts directly upon the tailpiece of the latch bolt assembly to retract the latch. When the outer door handle is operated, the outer retractor presses on the inner retractor, causing it to retract the latch. If there is an attack, a blocker assembly engages with members formed in the outer retractor to render the outer retractor inoperative to move into a latch-retracting position without interfering with operation of the inner retractor to move into a latch-retracting position.

A door lock has an inner door assembly, an indoor doorknob assembly, and an outdoor doorknob assembly. The inner door assembly has a locking assembly casing. The indoor doorknob assembly has a positioning resilient component located in the locking assembly casing and configured to switch the door lock between a locked state and an unlocked state. The door is provided with enhanced protection by enclosing the positioning resilient component in the locking assembly casing, so the safety is further improved.

A door lock chassis has a gauge insert that defines different dimensions corresponding to different door thicknesses. The gauge insert is positionable in the lock chassis in different orientations corresponding to the different dimensions used to align the lock chassis for different door thicknesses. Additionally, a door lock may include an anti-rotation assembly for preventing rotation of the lock chassis. The anti-rotation assembly may include a retention member that is secured to an inside hub of a lock chassis. As an anti-rotation member is displaced in a first axial direction along the inside hub to a mount position, the anti-rotational member may deflect resilient members of the retention member. With the anti-rotation member at the mounted position, the anti-rotation member may be in a frictional engagement with the previously deflected resilient members so that anti-rotation member is retained at the mount position.
