  • Patent number: 4247965
    Abstract: Over-center hinge for furniture doors, in which one of the hinge parts has a mortise cup manufactured of plastic, from whose circumferential wall a diagonally disposed tongue which is integral with the mortise cup and can be flexed against spring bias, projects into the interior of the mortise cup, and on which, during a portion of the movement of the hinge, a contact surface provided on the other hinge part at its end facing the pivot, slides and can be moved in an intermediate position through a dead point on one side of which it urges the door to the closed position and on the other side of which it exerts a pressure in the opening direction. The contact surface is so disposed that, in the closed position, it lies in the direct vicinity of the pivot axis of the tongue.

  • Patent number: 4210980
    Abstract: A hinge for cabinet doors or lids, especially for period furniture, having two visible sleeve-like hinge parts which can be fastened to the supporting wall of the cabinet and to the cabinet door or lid, respectively, and which are swingable relative to one another about the longitudinal axis of a pintle held in one of the hinge parts and engaging a complementary bore in the other hinge part. The pintle is made in one piece with a mounting pin added at approximately right angles to its end held in the hinge part and fastenable in a bore of the associated cabinet part. The visible, sleeve-like hinge part holding the pintle has on the side facing the associated cabinet part an aperture through which the pivot pin can be passed during assembly and from which the mounting pin protrudes. The pintle and the mounting pin are held in the position correctly aligned with the sleeve-like hinge part by a plug pushed onto the mounting pin and plugging up the aperture in the hinge part.

  • Patent number: 4187580
    Abstract: Hinge for furniture doors, having a door-related hinge part in the form of a cup-like element for mounting in a recess in the door, in whose circumferential wall a sloping, separately manufactured knuckle subject to the effect of a compression spring is mounted for pivoting by a given angular mount and during at least a portion of the opening or closing movement slides on a bearing surface provided on the other hinge part at its extremity facing the joint and is movable past a dead-center position on this side of which it urges the door to the closed position and beyond which it exerts a pressure in the direction of opening, the bearing surface being situated adjacent the fulcrum of the knuckle when the latter is in the closed position. The knuckle terminates at its bottom end pivotally mounted in the cup-like element in a transversely disposed, relatively narrow edge and is inserted in an upwardly facing deepened fulcrum pocket.

  • Patent number: 4184228
    Abstract: Cabinet hinge having two hinge links pivotingly attached to a door-related member on the one hand and to a wall-related member on the other, in the manner of a quadruple knuckle joint, wherein in the space between the hinge links, a resiliently deformable damping means is disposed such that, upon a swinging of the hinge into the open position, it is deformed while resting against at least one of the hinge links shortly before reaching the designated end position.

  • Patent number: 4154343
    Abstract: See-through packaging for the self-service sale of furniture hinges in small quantities, consisting of a plastic box of appropriate size serving for the accomodation of the hinges, having a rectangular or square bottom and sidewalls projecting upwardly at right angles from the bottom, and being closeable by a cover of transparent plastic material. One of the sidewalls of the box has a lower height in comparison to the other sidewalls, and a flat wall section extending downwardly from the cover closes the opening formed above the wall of lower height.

  • Patent number: 4117569
    Abstract: A knuckle-joint over-center hinge, in combination with a first member for connection to a wall and a second member for connection to a door, and a first arm and a second arm, respectively, pivotaly linked to the first and second member, and an over-center mechanism forcing the hinge resiliently towards one of its end positions. The mechanism includes a closing spring having one end disposed and supported at the first arm which has a portion of U-shaped cross-section and a transverse wall. A pusher is displaceably mounted in the first arm, while the closing spring is disposed within the U-shaped portion and supports itself with its one end on the transverse wall, while the other end of the spring engages the pusher. The first member has a cam projection in the vicinity of the point where the first arm is pivotally linked to the first member, and the pusher supports itself on the cam projection.

  • Patent number: 4091499
    Abstract: Mounting plate for the installation of the supporting wall part of a cabinet hinge on a piece of furniture. The mounting plate is composed of a bottom piece to be applied directly to the supporting wall and a top piece displaceable on this bottom piece parallel to the hinge pivot axis and mounted thereon for selective fixation. The bottom piece and top piece can be fixed together on the supporting wall by means of two fastening screws spaced apart from one another in line with the adjustment direction and passing through apertures in the top and bottom piece, which screws can be driven into bores in the supporting wall. The openings in the top piece are in the form of elongated openings extending in the adjustment direction so that the top piece is displaceable in the elongated holes relative to the bottom piece when the fastening screws are loosened.

  • Patent number: 4091501
    Abstract: A knuckle joint hinge, especially for rabbeted doors of period furniture, having a supporting wall part and a door part, a knuckle joint mechanism joining together the two parts and having two link arms recoupled pivotingly with one another in their middle area, one of the ends of the link arms being coupled to the supporting wall part of the hinge in the one case and to the door part of the hinge in the other, while the other end in each case is coupled to the other hinge part either in a sliding guide or indirectly through a link. The articulation point of the link arm directly articulated to the door part of the hinge is provided immediately beside the edge of the door which is to be hinged and in front of the face edge of the supporting wall, and the parts of the door part of the hinge and of the link arm, which are visible when the door is closed, have the appearance of the articulation of a single-pivot hinge having visible sleeves joined by a hinge pin.

  • Patent number: 4085481
    Abstract: A hammer-set housing for furniture hinges, having a hammer-set cup which can be pressed into a bore of suitable undersize in a furniture part, and which has at its outer margin a projecting lip which rests in a specified installed position on the flat outside of the furniture part and is adapted to be fastened to the door by additional mounting means, the hammer-set housing having a first part visible in the installed state and consisting essentially of metal, and also having a second part including two lateral plastic arms to be placed in the area within the bore in the furniture part. A flat lip unites the lateral plastic arms so as to form an integrally coherent plastic part, a dish-shaped metal part open at the top being inserted between the plastic arms, and a flange covering the plastic lip projecting integrally from the upper margin of the metal part. The plastic part and the metal part are joined together releasably.

  • Patent number: 4021881
    Abstract: A housing for supporting furniture hinges and for insertion into a corresponding recess of a furniture piece consisting of a plug-in casing connected to a flange plate and a hollow plug-in pin. An eccentric part is pivotably mounted within the plug-in pin and has an eccentric segment which is in contact with a flat locking member disposed in the housing. The locking member has a pair of locking arms which are offset from the plane of the body of the locking member. The peripheral edges of these arms are beveled to form cutters and arranged so that when the housing is inserted in the recess of a furniture piece, and the eccentric part is pivoted, the cutters will draw the casing into the corresponding furniture recess. In another embodiment, the plug-in casing is provided with a bearing pin to guide the locking arms in the casing slots. The bearing pin is also the bearing axis of the hinge guide.
