The present invention relates to a mounting plate (30) for an adjustable mounting of a hinge supporting arm on a cabinet. The mounting plate is made by punching and pressing operations from sheet metal, of a U-shaped cross section at least in an upper section facing the supporting arm to be mounted thereon. The mounting plate has in its cabinet-interior end area a threaded bore for a screw (38) locking the hinge supporting arm, plus an open-ended longitudinal slot (39) at its end pointing out of the cabinet interior. Along the margins of the web (52) of the mounting plate (30), which laterally define the slot, ridges are raised from the plane of the web (52), and the distance measured from one flat side of the undeformed web to the opposite boundary surface of the upturned ridges is greater than the material thickness of the web (52) in the undeformed area.

Mounting plate for furniture hinges and method for manufacturing it

Mounting plate assembly for cabinet hinges

Mounting plate for the adjustable mounting of the supporting wall-related part of a cabinet hinge composed of two separable mounting plate members of which the bottom mounting plate member nearer the supporting wall can be fastened fixedly to the supporting wall and the upper mounting plate member more remote from the supporting wall and adjustably mounting the carcase-related part of the cabinet hinge can be joined by a spring catch mechanism to the bottom mounting plate member. The bottom mounting plate member has in its front end area facing the door leaf at least one projecting hook with which a hook receiver on the bottom of the upper mounting plate member is associated. The upper mounting plate member partially overlaps the bottom mounting plate member at least in its end area pointing into the carcase interior, and in the overlapping area is provided with two tongues resiliently flexible parallel to the supporting wall surface; the tongues have each a catch section and the catch sections are form-lockingly caught each by an associated catch receiver in the bottom mounting plate member, the catch sections and the catch receivers being at an angle between 30.degree. to 60.degree. with respect to the longitudinal central axis of the mounting plate. By bending the tongues toward one another parallel to the supporting wall surface the catch sections and catch receivers can be brought out of engagement, the upper mounting plate member then being able to be swung upward by using sections of the tongues as finger grips.

The invention relates to a carcase-related part of a cabinet hinge, which is an elongated, channel-shaped supporting arm, releasably fastened on the mounting plate by a catch mechanism. The catch mechanism has at the outer end of the mounting plate and supporting arm, a hanger device enabling the supporting arm to tilt relative to the mounting plate. At the inner end of the supporting arm where it straddles the mounting plate, two tongues are provided which can be flexed resiliently parallel to the cabinet wall surface. Each tongue bears a latch section which can be engaged in an associated catch in the mounting plate. The hanger coupling of the supporting arm and mounting plate has an at least partially spherical holding head which is introduced into a slot conforming approximately to the shape of the holding head.

Cabinet hinge with adjustments

Cabinet hinge whose door-related part in the form of a cup set in a mortise is articulated to the carcase-related part configured as an elongated supporting arm of inverted U-shaped cross section by two hinge links whose ends are journaled in the cup at one end and on the supporting arm at the other. A closing mechanism is provided in the door-end of the supporting arm and has a cam surface configured nonrotationally on the inner hinge link. A resiliently deformable section of one leg of a substantially U-shaped leaf spring engages the cam surface with bias, and the end remote from the cup of the other leg is fastened inside of the supporting arm by a section of the web of the latter. The inner hinge link has at the end by which it is mounted in the supporting arm two parallel ears formed by tabs cut and bent at right angles from the lateral margins of its end inside of the supporting arm. The cam surface is formed in the area of the bottom of the inner hinge link that is between the ears, and the resiliently springing leg of the leaf spring in contact with the cam surface is under a bias seeking to bring its free resilient end toward the second leg held in the supporting arm.

The hinge has a closing mechanism having a cam element disposed at the inner end of the inner hinge link, which is joined corotationally with the hinge link, and on whose cam surface a resiliently flexible section of one leg of a substantially U-shaped leaf spring lies under bias while its second leg is joined to the outer end of the resiliently flexible leg in the interior of the supporting arm by a bridging section and thrusts against the interior of the supporting arm. The inner hinge link has at its inner end two parallel ears spaced apart from one another, between which the cam element is disposed for corotation therewith.

Furniture hinge whose cabinet-related part is configured as a supporting arm of channel-shaped cross section astride the corresponding mounting plate, the mounting plate being composed of two separable members which are adjustable relative to one another. The bottom mounting plate member can be fastened to the cabinet and the upper plate is releasably joined to the supporting arm by a catch mechanism. The catch mechanism has projections extending from its opposite lateral surfaces in the door end of the upper mounting plate member while at the inner end of the supporting arm more remote from the door at least one resilient tongue having a catch section is formed, which engages a catch recess on the inner end of the upper mounting plate member. The supporting arm straddles the upper mounting plate member at least at its end pointing into the cabinet interior, and is provided in the straddling area with two tongues which are resiliently flexible parallel to the supporting wall surface. Each tongue has a catch section which is matingly engaged with an associated catch recess in the upper mounting plate member. The catch sections and the catch recesses can be brought out of engagement by squeezing the tongues together. Each tongue has a handle which is accessible when the supporting arm is mounted on the upper mounting plate member, for the purpose of squeezing the tongues together parallel to the supporting wall surface.

Furniture hinge

Over-center self-closing hinge for cabinet doors, having an inner link and an outer link in a quadrilateral arrangement and a lever in the form of a hairpin spring fulcrumed at one end in the cabinet-wall-related hinge part and thrusting at right angles to the hinge axis against a cam which is journaled on the inner link and abuts in its one position against the pivot eye of the latter and in its other position against the link itself. The cam is of such a configuration that, when the hinge is moved from the open position to the closed position, just before it reaches the closed position, the line of thrust applied by the hairpin spring passes through the pivot axis of the link, but then the spring passes over onto a portion of the cam associated with the second position of the latter, thereby causing the cam to rock over and alter the line of thrust of the spring such that it seeks to close the hinge.

Over-center self-closing hinge for cabinet doors

Cabinet hinge whose mounting plate serving for the adjustable attachment of the carcase-related part of the hinge to the carcase of a cabinet is composed of two parts, i.e., of a bottom plate and a top plate. The bottom plate has in its outer end adjacent the door at least one hook rising from the plane in which it is fastened to the carcase and pointing outwardly, which can engage an associated eye in the bottom of the upper plate. The confronting surfaces of engagement between the hook and the eye are of complementary configuration and at least approximately arcuate with the centers of the arcs coinciding approximately with the center of the angular displacement described by the hinge in the first part of its closing movement relative to the door-related part of the hinge. A spring catch mechanism with a handle is provided in the bottom plate for the purpose of the releasable attachment of the top and bottom plates to one another.

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.

A guide for drawers, cutting boards and other such retractable furniture parts, having a guide rail which can be fastened to a cabinet wall, and a running rail which can be fastened to the retractable furniture part and is mounted for movement along the guide rail with the interposition of rolling bearings held in a cage. The running rail is a hollow rail that is open on one side in a slot running in the direction of movement and has rolling-bearing tracks disposed in a triangle with one another in a cross section through their longitudinal central axes, one of the tracks being provided opposite the slot and the other two tracks being provided on opposite sides laterally of the slot, and the guide rail being provided on its end reaching through the slot into the interior of the running rail with three tracks which confront the tracks of the running rail in the same arrangement. At least in the interstice between the running rail track opposite the slot and the corresponding track of the guide rail, rollers are disposed with their central axes disposed transversely of the direction of the drawer movement.

Drawer guide

In an adjustable-height mounting plate for cabinet hinges, the mounting plate has a bottom part which can be fastened directly to a cabinet wall, and a top part provided with means for fastening the supporting arm of a cabinet hinge, the top part being mounted on the bottom part through the medium of interfitted guide means for displacement parallel to the hinge pivot axis and for locking at any desired point. When in the superimposed state, each part has an elongated central section from each of whose opposite sides a wing-like projection extends. In one of the wings of the top part there is provided a slot running in the direction of displacement, through which a clamping screw passes when it is driven into a tap in the bottom part to clamp the two parts together. In the other wing of the top or bottom part there is provided a second slot running in the direction of displacement, which is engaged by a short shaft-like projection protruding from the bottom part or top part, as the case may be, on whose free end there is provided a holding head laterally overlapping the margins of the slot with slight clearance, which prevents unintentional separation of the top part from the bottom part.

Cabinet hinge whose cabinet-wall-related part in the form of a cantilever arm can be slipped onto a mounting plate installed on the wall of a cabinet and can then be fixed at selected positions on the mounting plate by tightening a screw. The mounting plate bears a resilient catch which, at the beginning of the installation of the cantilever arm engages an abutment on the latter and thus secures it against accidental withdrawal from the mounting plate, without interfering with its movement for longitudinal adjustment on the mounting plate. The catch is provided on a leaf spring which is fastened at one end within the mounting plate while its free end bearing the catch protrudes through an opening in the mounting plate. The arm-holding screw is passed with clearance through an oversize hole in the mounting plate and driven into a threaded eye in the leaf spring.
