  • Patent number: 6880205
    Abstract: A hinge for anchoring a door leaf (2) to a frame (1) of an item of furniture has a base plate (5) that may be secured to the frame (1) and an intermediate piece (3) on which there is mounted a hinge arm (4) connected to a hinge pot (8) that may be secured to the door leaf (2) by way of at least one articulating pin (9). An adjusting and/or fixing mechanism is provided by means of which the hinge arm (4) may be fixed in different positions on the intermediate piece (3). The intermediate piece (3) is provided with a bracket (15) that has lateral marginal projections (15?) and is punched out of the intermediate piece (3). The hinge arm (4) has a region that is C-shaped in cross-section. Inwardly directed projections (7) of this region reach behind the marginal projections (15?) of the bracket (15), as a result of which the hinge arm (4) is anchored to the bracket (15).

  • Patent number: 5463796
    Abstract: A hinge pot has a housing which can be inserted into a bore in a furniture part and dowel-type expandable clamping jaws which can be inserted in the bore and which can be pressed against the bore wall by way of expanding members constructed as tie rods. The expanding members are movable by way of an eccentric lever in the direction of insertion of the hinge pot perpendicular to the plane of mounting thereof. The clamping jaws are cylinder sections of visco-elastic material. The expanding members are metal, are located between the hinge pot and the respective clamping jaws, and have hooks at their free ends. Opposite the hooks are provided contact pressure cams which are supported against a housing wall of the hinge pot.

  • Patent number: 5056189
    Abstract: A hinge with an adjusting system includes a hinge arm that can be secured to a base plate by at least one adapter. The hinge arm has holes through which pass adjusting and attachment screws. The adapter can be installed on the base plate and can be locked by means of a rocker lever supported on the adapter so as to be able to swivel. The adapter is U-shaped and has two side arms that enclose the base plate and the sides thereof. Both side arms of the adapter lie with no clearance on the base plate, and the material of at least one of the side arms is weakened at at least one place. The adapter is installed at the front by a cross pin thereof fitting in a notch in the base plate. The shape of the notch corresponds to that of the cross pin, and the cross pin is accommodated without any play within the notch. The generators or the center or mid-line longitudinal axes of the notch and the cross pin extend unstressed at an angle relative to each other.

  • Patent number: 5056190
    Abstract: A hinge has a hinge arm which is connected by hinge links with a hinge casing and is mounted on a mounting plate by a joint adjusting screw and a depth adjusting screw. The hinge arm is, at an end thereof which is close to the pivot axis of the hinge, engageable with the mounting plate by a rigid hook and is pivotable about this point of engagement. At its opposite end, the hinge arm has structure forming a resilient snap connection which engages the mounting plate and maintains the hinge arm mounted on the mounting plate. The structure forming the resilient snap connection has extending therefrom a handle member for enabling the resilient snap connection to be released by lifting the handle member away from the mounting plate.
