Improved door latch assembly with accelerated bolt motion, deadbolt and replacement face plates

A door latch has an adjustable cam (25) to accommodate two backsets of the bore (24) through a door. The cam (25) is operably attached to a handle (14). Rotation of the handle (24) approximately 45{ fully retracts latch bolt (54) and deadbolt (56) through a slide actuator (100) that pulls a link (112) which pivots a cam lever (104) that retracts the bolt (54). The bolt (54) retracting motion is magnified with respect to the motion of actuator (100) via the link (112) and cam lever (104). The link (112) and cam lever (104) are mounted within cylinder section half (52) of housing (28) so as not to interfere with the deadbolt (56) and its slide (150) and deadbolt locking plate (170) that are mounted in a complementary cylinder half (51).

Push button lock mechanism for a handle set

A handle set includes a handle assembly having an operator, a rose insert, and a shank having a bore. The rose insert has a central opening and a post. The shank is affixed to the operator and rotatably received in the central opening. A rotational stop is coupled to the rose insert. A spindle guide is slidably received in the bore and is slidable between a locked position and an unlocked position. A kick-off plate having a retention slot is coupled to the spindle guide. A centralizing cup having a single multi-function tang and a lock retention feature is mounted to the shank. The multi-function tang is configured for rotation along a rotational path, the rotation being limited by the rotational stop. The lock retention feature is positioned to engage the retention slot when the spindle guide is in the locked position to thereby retain it in the locked position.

Chassis for a lock set

An interconnected chassis includes a mounting plate including a spring engaging tab. A cover plate includes a recessed spring retention wall. A lower cam has a lower pivot axis. An upper cam has an upper pivot axis. A slide plate is positioned between the mounting plate and the cover plate, the slide plate having a spring retention slot and a spring support ledge. The slide plate includes a first end having a pivot feature and a second end having a lower cam engagement member for engaging the lower cam. A spring is positioned in the spring retention slot of the slide plate and in the recessed spring retention wall of the cover plate, and between the spring engaging tab of the mounting plate and the spring support ledge of the slide plate. A toggle is pivotably coupled to the slide plate by the pivot feature, the toggle having a head portion positioned to engage the upper cam.
