  • Patent number: 4797972
    Abstract: The insert cup for cabinet hinges is made from stamped and drawn sheet metal and can be sunkenly mounted in a cylindrical mortise in the area adjacent the edge of the inside face of a door leaf. It has a tub- or trough-like portion having on its upper edge a marginal flange which covers the interstice between the tub-like portion and the circumferential wall of the cylindrical mortise and, at least at a sector-shaped portion, lies matingly and flush within the mortise. On the margin of the sector-shaped portion of the flange there are provided integral guiding lugs which are bent downwardly at right angles into the interior of the cylindrical mortise and which center the insert cup in the proper installed position and secure it against displacements in the plane of the door leaf.

  • Patent number: 4642846
    Abstract: The cabinet hinge mounting plate can be fastened to a cabinet wall by means of screws passing through openings provided in it in the form of slots. The slots are configured such that the screws associated with each of them, which are threaded only on a portion of their length but have an unthreaded section adjacent the screw head, will be held temporarily by their threaded portion in a central position in the length of the slot, but when they are driven all the way in they will be displaceable lengthwise of the slot. The slots have in the area of their central portion projections protruding each toward the opposite slot edge for the purpose of holding the crests of the threads of the associated fastening screws. At their upper side facing the head of the screws the slots are provided with a rebate which is engaged by a centering section of the screw, which is formed in the transition between the head and the shaft of the screw.

  • Patent number: 4641393
    Abstract: The supporting arm of a cabinet hinge is adjustably mounted on a mounting plate to be attached to the supporting wall of a cabinet and has at its cabinet-internal end an open-ended longitudinal slot through which passes a screw fastening it to the mounting plate. A setscrew is threaded in a tap situated adjacent the front or outer end of the supporting arm and has at its bottom end adjacent the mounting plate a holding head in the form of a spherical body having a circumferential annular groove formed in rotational symmetry with the longitudinal axis of the setscrew. The holding head is inserted into an open-ended longitudinal groove having a narrow mouth, the cross section of the groove being substantially complementary to the cross section of the holding head in a plane in the longitudinal axis of the setscrew, so that the holding head is accommodated so as to be longitudinally displaceable in the longitudinal groove but secured against lifting out of the groove.

  • Patent number: 4622716
    Abstract: The door-related part of a cabinet hinge is in the form of a cup insert having a cup part which can be sunk flush into a recess in the back of a door. On the upper, free margin of the cup part a fastening flange integral therewith extends symmetrically with the longitudinal central axis on opposite sides of the latter, against the back of the door. From the bottom of the fastening flange projects a fastening stud engaged in a bore in the door adjacent the recess. This fastening stud is provided adjacent its free end with a knife-edged projection. Due to a special configuration, the fastening stud can be introduced into its corresponding bore in a canted position when the cup is installed. By a final rocking of the cup from the canted position in which it was inserted to the intended installed position, the knife-edged projection is forced into the wall of the bore receiving the fastening stud and positively locks the fastening stud against withdrawal from the bore.

  • Patent number: 4611957
    Abstract: A fixture for the adjustable mounting of board-like furniture parts on the work table of a drilling machine. Underneath the drilling head of the machine, backstop rails which project slightly above the supporting surface of the work table are disposed in alignment with one another and longitudinally displaceably at equal distances on opposite sides of a longitudinal central plane. The ends of a threaded spindle are threaded into the ends of the backstop rails adjacent the drilling head, the threaded spindle being provided on each half with contrary threads of equal pitch. The threaded spindle is mounted rotatably but in a longitudinally undisplaceable manner on the work table. Cursors are longitudinally displaceable on the upper sides of the backstop rails and can be fixed at given uniform distances on the associated backstop rail, and each bears a stop which is biased to a position projecting toward the surface of the work table, and which can be retracted into the cursor against the bias.

  • Patent number: 4517706
    Abstract: Cabinet hinge having a supporting arm which can be snapped onto the mounting plate. The supporting arm (16) of the hinge is adjustably fastened to the mounting plate (14) that is previously mounted on the supporting wall (12) of a cabinet, and it has a slot (34) which is open at the end remote from the hinge articulation or is provided with an enlarged pass-through opening to admit the head (38) of a mounting screw (40) driven into the mounting plate (14). The mounting plate (14) is provided with a spring catch (wire spring 72) projecting beyond its lateral surface and associated with an abutment on the confronting inside surface of the supporting arm (16). The position of this abutment with respect to the tip (78) of the spring catch is selected such that the tip engages the abutment as soon as the shank of the mounting screw (40) reaches the area of transition from the slot (34) to the pass-through opening (36) or open end, as the case may be, of the slot.

  • Patent number: 4506409
    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.

  • Patent number: 4499631
    Abstract: Furniture hinge (10) in the form of a four-joint hinge whose door-related part constructed as a recess-mounting cup (12) is pivotingly coupled by a four-joint mechanism formed by two hinge links (14;16) to a carcass-related hinge part which can be fastened to the carcass of a cabinet. One of the hinge links (14) is wider than the other hinge link (16) and, in the area between its ends, the wider hinge link (14) has an opening (38) whose width is equal to or greater than the width of the narrower hinge link (16). Therefore, when the hinge is in the open state, a portion between the ends of the narrower hinge link (16) can enter into the opening (38) in the wider hinge link (14), so that a larger opening angle is achieved than in the case of conventional four-joint hinges.

  • Patent number: 4500140
    Abstract: A slide for drawers and the like, to be provided in pairs on opposite sides of a drawable furniture part and an associated carcass wall. It has a profiled cabinet rail (26) to be connected to the carcass wall (14) and a drawer rail (18) to be connected to the drawer. At the front end of the cabinet rail and at the rear end of the drawer rail there is rotatably journaled a roller (32;24) running on the drawer and cabinet rail respectively. An adjusting key (34) is longitudinally displaceably arranged at the cabinet rail and rests against the drawer rail. The connection of the key at the cabinet rail is such that, upon longitudinal displacement, a displacement component transverse to the drawing direction is superimposed on it, whereby an adjustment of the transverse play of the drawer between the carcass walls is possible.
