Abstract: A spring system for stabilizing bifolding door hinged positions includes an integral "C"-shaped spring with at each end of the "C"-shape a respective straight shank formed at right angles to the plane of the "C"-shape in parallel spacing from each other. On each shank is a rotatable tubular sleeve bearing with a collar-shaped enlargement at the end adjacent the "C"-shape, and a retainer on the free end of each shank that keeps the tubular sleeve bearings in place. Installation is by insertion of the tubular sleeve bearings in parallel-spaced drilled holes in the top edges of two doors that are hinged together so that the spring assembly substantially bridges the hinges and biases the faces of the doors together to keep them in the open position, and biases the edges of the doors together to keep them in the closed position.

Abstract: A hinge for mounting an access door on a room air conditioner has a hinge member having a tang at one end engaging a slot on the air conditioner front frame to mount the hinge member in a fixed position. The other end of the hinge member has a pair of resilient legs interspaced by a projection and which carry projecting trunnions on their outer ends. The door has a notch in its side having opposed side walls with bores that receive the projecting trunnions to pivot the door about the hinge member. The hinge provides a self-latching arrangement by a projecting, resilient tongue on the hinge member which engages a projecting lug on the door to resiliently bias the door to a closed position when it is within a predetermined distance from the closed position.

Abstract: A single-pivot cabinet hinge (10) for hanging doors has a cup (12) which can be fastened in a gain in the back of a door (16) and in which there is journaled one end of a pivot arm (24) whose other end bears a fastening plate (28) having a slot (30) engaged by a projection (60) of a mounting element (34) which can be fastened to the carcass of the cabinet. The fastening plate is displaceable on the mounting element (34) under the guidance of the projection and can be fixed at selectable positions by means of a fastening screw (50) which can be driven into the projection. The projection in turn is continuously adjustable in the mounting element (34) at right angles to the longitudinal axis of the slot and likewise fixable at selectable positions, so that the pivot arm together with the door cup is adjustable relative to the mounting element, and therefore a door hung by the hinge on a cabinet carcass is adjustable relative to the cabinet carcass, in coordinate directions at right angles to one another.

Abstract: An over-center self-closing hinge for furniture. In the door-related part of the hinge, which is in the form of a cup to be set in a mortise, there is provided a resiliently biased, pivotingly mounted cam which, in cooperation with a contact surface on the jamb-related part of the hinge, forms the over-center mechanism. Within the hinge cup there is provided a swivel arm which can be swung upwardly to a position in which it holds the resiliently biased cam in its dead-center position. With the swivel arm there is associated a resilient element which seeks to swing it up into the raised position. The resilient element is preferably an elastically flexible arm reaching beneath the swivel arm and joined fixedly to the cam adjacent the pivot axis thereof.
