And Stop Or Abutment For Pivotal Movement Patents (Class 16/363)
  • Patent number: 4536958
    Abstract: A tool, particularly a nut-cracker, consisting of two twin elements each having at one end a projection shaped as a cylinder sector surrounded by an annular element forming an eyelet and by a circle sector shaped tongue, concentrical with respect to said cylinder sector shaped projection, so as to attain, by inserting said projection of one element into the eyelet formed by the annular portion of the other one element, a tool with two elements or movable hinged arms, with a rotational axis coincident with the geometrical axis of said cylinder sector projections.

  • Patent number: 4501045
    Abstract: A self-locking hinge is disclosed for pivotally attaching a door to a frame member. The hinge includes first and second hinge members which are pivotally joined together by a pin. A socket is formed in the first hinge member which is designed to receive a detent mechanism. The detent mechanism has at least one tooth formed on its lower surface which will engage a complimentary notch formed on the upper surface of the second hinge member upon rotation of the first hinge member relative to the second hinge member. The tooth and notch are so configured as to permit rotation of the first hinge member in one direction but will prevent its rotation in an opposite direction once the tooth has engaged the notch. A spring is positioned located within the socket of the first hinge member so as to bias the detent downward towards the second hinge member.

  • Patent number: 4472857
    Abstract: In the door stop, the arm which is pivotally mounted on the door has the shape of a flat strip against the respective edges of which strip are applied under elastically yieldable pressure two rollers. The first roller, which, in the open position of the door, is engaged in a stop notch, is fixed in position, whereas the other roller is rotatably mounted on a transverse portion of a stirrup which connects adjacent end portions of two helical windings of a torsion spring. Each roller comprises two rings which are fitted one inside the other and have a sliding contact between each other, with the pins on which they are mounted, with the arm and with inner faces of a bracket carrying the pins.

  • Patent number: 4470170
    Abstract: A hinge arrangement for various types of movable objects, such as doors, windows, flap members and so forth. In the case of thick-wall doors having shutters or ornamental strips mounted thereat, equally in the case of double doors, windows or flap members or similar type structures, especially in the construction and furniture industry, there exists the difficult problem of adjusting the pivoting movement of the door or other structure. Usually, there only can be attained opening angles of the door or other movable structure up to a range of about 180.degree.. A hinge arrangement is disclosed which affords a relatively wide pivoting of the door or other structure during opening thereof, the pivoting movement being adjustable as to the degree or width of opening of the door or other structure. The hinge arrangement also allows opening angles of the door or other structure of 270.degree. and more.

  • Patent number: 4449269
    Abstract: A furniture hinge for two housing parts has a housing mounted on one furniture part, a hinge arm mounted on the other furniture part, two pivotable hinge plates pivotally connecting the housing with the hinge arm, a spring which forms a locking device, a cylinder-and-piston unit having a piston pivotally mounted on the hinge arm and a brake cylinder slidably movable relative to the piston under the action of a cam lever mounted on one of the hinge plates and arranged to move the brake cylinder relative to the piston, wherein the sliding surface of the brake cylinder and/or the piston has a friction-increasing coating.

  • Patent number: 4386450
    Abstract: A hinge for display panels and the like that holds a movable panel in any of two or more fixed positions about a horizontal axis. The hinge consists of a fixed bracket containing matching curvilinear slots which enclose tabs extending from a movable panel. Gravity and friction hold the movable panel in a storage position; from that position the panel is easily moved downward and forward simultaneously, to another predetermined position.

  • Patent number: 4381581
    Abstract: A three-part hinge mechanism is disclosed as a concealed hinge with two of the parts being first and second mounting brackets interconnected by a link. The first mounting bracket has means for mounting on an enclosure and the second mounting bracket has means for mounting on a cover for the enclosure. The hinge is concealed and permits the cover to be lifted or translated directly away from the enclosure by a sliding connection within the hinge and then the sliding connection becomes also a pivotal connection so that the cover may be pivoted to one side. This permits a relatively deep cover to enclose components mounted within the enclosure and closely adjacent the walls of the cover. By the first translational movement, the cover will clear these components and then the cover may be pivoted to one side. Additionally, the hinge may be readily connected and disconnected so that the cover may be completely moved out of the way for access to the components within the enclosure.
