Abstract: Upper and lower three-piece hinge assemblies enabling a door to be attached and removed in a precise lateral take-apart manner during a vehicle body assembly line operation. Each of the hinge assemblies each provide a body-half mounting hinge and a door-half sub-assembly. The sub-assembly comprises a link plate and a door-half mounting bracket permanently pined together by a door hinge pin. Prior to removably attaching the door-half sub-assembly to the body-half hinge an installer inserts an abutment peg in a through bore of a bracket horizontal wing. The installer then rotates the link plate about its hinge pin until it engages the peg forming, with the bracket, a wedge-shaped receptacle adapted to slidably receive therein a complementary wedge-shaped foot plate of the body-half hinge. The receptacle seats on the foot plate in a predetermined abutting manner enabling each link plate aperture to be self-aligned with an associated foot plate threaded hole.
Abstract: This invention relates to a support and guide element for movable, suspended door and wall elements. The support and guide element is designed so that a smooth movement can be securely executed, even in the vicinity of junctions and intersections. This is achieved because four support rollers are fastened to a square support roller cage block, but where only two of the four support rollers support the weight of the door or wall element in the running direction of the door or wall element. The other two support rollers are oriented at right angles to the running direction, and, during movement of the door in the running direction, only come into contact with the roller rail at a junction or intersection. Above the running rollers there are guide rollers, which guarantee secure guidance of the wall element.
Abstract: A door closer comprises a housing containing a cylinder and two movable pistons. When the associated door is opened, both of the pistons and the cylinder are moved relative to the housing to draw oil into the cylinder. Expulsion of oil from the cylinder through an orifice on closing of the door controls the closing movement.
Abstract: A hanger device for hanging a curtain to a curtain rod via a curtain runner reciprocally mounted on the curtain rod. The hanger device comprises a hanger body attached to the curtain and a hook portion pivotally mounted on the hanger body and adapted for hooking engagement with a curtain runner. When the hook portion is angularly moved to an inclined position, the hook portion is locked to the hanger body against unnecessary oscillation, so that the hook portion is quite immune from be entangled with the curtain during laundering of the curtain.
Abstract: The invention relates to a hinge for the constraining of a hatch or door from a support structure.

Abstract: A universal hinge is a hinge with the capability of performing stop and hold mechanisms without installing extra stop and/or catch components on an object abutted to the universal hinge. The universal hinge comprises a hinge body, a stop mechanism, and a hold mechanism. Both the stop mechanism and the hold mechanism of the universal hinge are provided by specially shaped hinge knuckles while no extra component is needed. An alternative improvement of the universal hinge is provided by adding a specially designed self-locking spring-bushing assembly which comprises a conical spring and a step-configured ring bushing. The self-locking spring-bushing assembly complying with the stop and hold mechanisms can serve the improved universal hinge with the adjustable stop angle capability.
Abstract: A 180.degree. concealed hinge includes two pivots which are advantageously arranged to provide a deterministic opening sequence. The hinge comprises a frame leaf member and a door leaf member which are pivotally connected to a mounting leaf member. In one embodiment of the invention, the deterministic opening sequence is obtained by employing a loose fit pivot and a friction fit pivot. The deterministic opening sequence is such that rotation occurs first about the loose fit pivot from a closed position to an approximately 90.degree. open position when an opening rotational force is applied to the door leaf member. Upon reaching the 90.degree. open position, further rotation about the loose fit pivot is prevented by a unique stop arrangement. Then, rotation can occur about the friction fit pivot for an additional 90.degree.. Further rotation about the friction fit pivot is prevented by also employing another unique stop arrangement.
