Abstract: A mortise lock for mounting in a door. The lock includes a bolt movable along a first axis between an extended position and a retracted position. Included are means for biasing the bolt to its extended position. The lock further includes a driven member which is mounted for rotation about a second axis generally perpendicular to the first axis. As the driven member is made to rotate about the second axis, it engages the bolt and urges it, overcoming the bias, to its second position. A drive member is mounted for rotation about a third axis, generally parallel to the second axis.

Abstract: A latch assembly for insertion into an edge of a door and adjustable for actuation by a half-round spindle at either a first backset or a second backset. The latch has an inner casing non-rotatably received within an outer casing and slideable along an axis. The inner casing is provided with a transverse void substantially perpendicular to the sliding axis and is slideable between a first position in which the transverse void is aligned at the first backset and a second position is which the transverse void is aligned at the second backset. A slide within the casing is, without adjustment, engageable by the half-round spindle at either backset. A cam is rotatably mounted within the casing and engaged to the slide and to a bolt also within the casing. The bolt is slideably retractable into the casing by rotation of the cam in response to sliding of the slide. A spring biases the bolt to an extended position extend out from the casing.

Abstract: A door handle assembly includes a bias mechanism that maintains inside and outer handles in a generally horizontal position in which a latching bolt of a latching bolt mechanism is fully extended, the latching bolt being retracted upon rotating either handle only about 28° from the horizontal retracting the latching bolt to allow opening of a door on which the door handle assembly is installed.

Abstract: A slide compartment for a hybrid lock architecture. The slide component comprises a U-shaped body portion and a plurality of independent retractors. At least one pair of slots are positioned near an open end of said U-shaped body for attachment of a drawbar of a door latch assembly of the hybrid lock assembly. The hybrid lock assembly comprises a chassis assembly mounted in a bore of said door. A door latch assembly is operably connected to the slide component housed in the chassis assembly for retraction and extension of a bolt. A handle is mounted on a spindle on each side of the chassis assembly. Rotational motion of either handle is converted to linear motion within the chassis assembly at the slide interface in order to retract the bolt of the door latch assembly.
