A latch assembly is provided where the latch is moveable to open and close a door by operation of a dead lock assembly that blocks or unblocks movement of a bolt. In a blocked state, a blocking cartridge of the dead lock assembly is prevented from inward movement, blocking inward movement of the bolt. Turning a door knob or door handle causes a spindle extending through the dead lock assembly to move locking bars of the dead locking assembly, the locking bars moving further apart to permit the blocking cartridge to slide there between and move inwardly into the latch housing. The bolt can now move inward by force of the doorjamb upon the bolt in order to clear the doorjamb when opening and closing the door.

A handle assembly includes a removable handle positioned over a sleeve. The handle assembly includes a catch positioned within the sleeve, and when extended, the catch prevents relative movement between the handle and the sleeve. The handle assembly includes a spindle positioned within the sleeve. The spindle has a longitudinal axis. The spindle is rotatable between a locked position and an unlocked position. When in the locked position, the sleeve is not rotatable, and when in the unlocked position, the sleeve is rotatable. The handle assembly includes a support structure that is configured to support the spindle. The support structure is in a fixed rotational relationship with respect to the handle. When the catch is in an extended position and the spindle is in the locked position, deflection of the spindle in a direction transverse to the longitudinal axis is resisted by way of the support structure.

An apparatus including a chassis assembly having a housing, a spindle rotatably mounted to the housing, a spring collar rotatably mourned to the housing, a first biasing element rotationally urging the spindle toward a spindle home position, and a second biasing element rotationally urging the spring collar toward a spring collar home position. The apparatus may further include a handle mounted on the chassis such that the chassis biases the handle to a handle home position with a return torque. The handle is engaged with the spindle such that the first biasing element contributes to the return torque. In certain embodiments, the handle may further be engaged with the spring collar such that the second biasing element contributes to the return torque.

A deadbolt assembly with a latch assembly and a lock cylinder. The deadbolt assembly includes a first torque blade longitudinally extending along a first axis and a second torque blade longitudinally extending along a second axis. The second torque blade is operatively coupled with the latch assembly to actuate the bolt between the retracted position and the extended position. The deadbolt assembly includes a geared arrangement operatively coupling the first torque blade and the second torque blade. The gear arrangement is configured to apply rotational movement of the first torque blade to the second torque blade.

A rose assembly for a door lock and a method of removably securing the rose assembly to a lock chassis. The rose assembly is secured to the lock chassis through the use of an intermediate spring steel attaching plate, which provides both a secure attachment to the lock and orientation of the rose assembly to the lock housing. A single spring plate with integrated retention clip features provides a removably attachable interface between the rose and the lock chassis. The spring plate includes a hook feature to provide positive retention of the rose that is independent of the spring clip features. Additionally, the spring clips are located to minimize the possibility that one clip deflects substantially more than another. The installation process includes inserting the hook feature into a slot in the chassis housing, and then snapping the clip features over the housing to seat and retain the rose.

A clutch includes an outer box and an intermediate member pivotably connected to the outer box. The intermediate member is coupled with an outer handle to pivot therewith. A torsion spring is disposed between the intermediate member and the outer box and biases the intermediate member to an initial position. A coupling member is pivotably mounted between the intermediate member and the outer box and is operatively connected to a first latch of a latch device of a lock device. When the coupling member and the intermediate member are jointly pivotable, pivotal movement of the outer handle causes the first latch to move from the latching position or the unlatching position. When the coupling member is not jointly pivotable with the intermediate member, pivotal movement of the outer handle is incapable of causing movement of the first latch. A lock device with the clutch is also disclosed.

A lockset with a sliding spindle assembly allows ingress using a key on the outside or a button on the inside. The sliding spindle assembly provides first and second sliding mechanisms operated from the outside and inside, respectively, that operate a clutch to couple the outside handle to the main spindle. Each sliding mechanism comprises a key cylinder or twist and/or push button lock that rotates a cam to linearly advance (slide) a cam follower that incorporates a spindle receiver. The first sliding mechanism slides its spindle receiver between clutching and non-clutching positions with respect to the main spindle. The second sliding mechanism slides the main spindle itself between clutching and non-clutching positions with respect to the first sliding mechanism's spindle receiver. The sliding spindle assembly can be incorporated into a legacy lockset and also be used in a double-latch lockset.

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.

An exemplary knob assembly includes a knob having a circumferential channel, and a deformable ring seated in the circumferential channel. The ring is normally rotatable relative to the knob such that rotation of the ring does not cause a corresponding rotation of the knob. When gripped with a sufficient gripping force, the ring frictionally engages and rotationally couples with the knob, thereby permitting transmission of torque between the ring and the knob. In certain embodiments, the knob assembly may include a detent mechanism operable to selectively couple the ring and the knob. In certain embodiments, the ring may include protrusions operable to engage pockets in the knob to provide for rotational coupling.
