The present invention relates to door furniture and methods of installation and particularly to door furniture for interior doors to minimize assembly issues.

The present invention relates to door furniture and methods of installation and particularly to door furniture for interior doors to minimize assembly issues.

A door handle assembly includes an interior chassis, an exterior chassis, and an alignment guide. The interior chassis includes an interior trim portion, an interior handle mount rotatably attached to the interior trim portion, and an interior spindle portion rotatable with the interior handle mount. The exterior chassis includes an exterior trim portion, an exterior handle mount rotatably attached to the exterior trim portion, an exterior spindle portion rotatable with the exterior handle mount and axially aligned with the interior handle mount, and a mounting post extending toward the interior chassis from the exterior trim portion offset from the exterior spindle portion. The alignment guide is removably attached to the interior trim portion and is formed of a resilient material. The alignment guide extends toward the exterior chassis from the interior chassis and includes an aperture aligned to receive the mounting post.

An apparatus comprising an inner part including an external thread and a slot with a non-circular cross section in a plane perpendicular to the screw axis of the external thread. The slot is configured to locate an elongate member with a corresponding non-circular cross section, such that when located in the slot the elongate member is rotatably fixed relative to the slot. The apparatus further comprises an outer part including an internal surface that comprises a threaded portion, wherein the outer part is configured to threadably rotate around the inner part.

An exemplary apparatus includes a modular, self-contained spring cage and a spindle. The spring cage includes a housing and a clock spring mounted in the housing, and the clock spring includes a first leg and a second leg. The spindle extends through the spring cage, and is rotatable from a home position about a longitudinal axis in each of a first rotational direction and a second rotational direction. Rotation of the spindle from the home position in the first rotational direction causes pivoting of the first leg while the second leg remains stationary, thereby causing the clock spring to urge the spindle to return to the home position. Rotation of the spindle from the home position in the second rotational direction causes pivoting of the second leg while the first leg remains stationary, thereby causing the clock spring to urge the spindle to return to the home position.

An exemplary catch assembly is configured for installation into a spindle, and generally includes a holder, a first catch, a second catch, and a bias mechanism. The holder is configured for mounting within the spindle. The first catch is mounted for movement relative to the holder between a first projected position and a first depressed position. The second catch is mounted for movement relative to the holder between a second projected position and a second depressed position. The bias mechanism biases the first catch toward the first projected position and biasing the second catch toward the second projected position.

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.
