Abstract: A hinge, preferably for hinging a door or flap to a carrying wall of a furniture corpus, comprises a cup-shaped hinged hinge member and a hinge bracket, which is articulatedly connected to the hinge member by two links and is adapted to be mounted on the carrying wall by a carrying plate. One of the links is extended in length beyond the pivot pin by which the link is connected to the hinge bracket, and that extended length portion of the link is so connected by a coupling link or by a guide slot to a pin which is mounted on the carrying plate or on an intermediate plate, which is adapted to be connected to the carrying plate, that the hinge bracket will be pivotally and longitudinally displaceably held on the carrying plate or on the intermediate plate by pin-slot guides during pivotal movement of the one link.

Abstract: A hinge, preferably for hinging a door or flap to a carrying wall of a furniture corpus, comprises a cup-shaped hinged hinge member and a hinge bracket, which is articulately connected to the hinge member by two links and is adapted to be mounted on the carrying wall by a carrying plate. The hinge bracket is movably mounted at one end on the carrying plate by a guide, and one of the two links is extended in length beyond the pivot pin by which the one link is mounted on the hinge bracket. At the free end of the extension, the hinge bracket is articulately connected to the carrying plate so that a pivotal movement of the hinged hinge member will impart to the hinge bracket a displacement along its guide and a pivotal movement.

Abstract: A rail switch (1), particularly for an overhead conveyor system, adapted to assume at least two switch positions (I, II, III) for selectively connecting a first rail (2) comprising a runway (2a, 2b) for casters (7a, 7b) of conveyor carriages (6) to the free ends of other rails (3, 4, 5). The switch includes a switch portion (10) carrying a corresponding runway (10a, 10b) and having one of its ends connected to the free end of the first rail (2) by a hinge (9) permitting it to be pivoted about a pivot axis (11) so that the opposite free end of the switch portion (10) may be selectively connected to the free ends of the other rails (3, 4, 5). To ensure substantially smooth passage of the casters (7a, 7b) over the hinge (9), the runway adjacent the hinge (9) is formed by mutually overlapping runway surface portions (17a, 17b, 19a, 19b) on the switch portion (10) and on the first rail (2).

Abstract: A torque control for providing a desired frictional resistance to a pivotally mounted vehicle accessory, such as an armrest or headrest, which includes a resilient member having an irregular arcuate slot. A resistance element extends in the slot to move along the length thereof as the pivoted component pivots about the pivot axis. In one modification, the shape of the slot provides a desired predetermined frictional resistance and in another modification a cutout is made in one of the walls of the slot permitting such wall to flex.

Abstract: A cap member for a window stay, particularly a four bar friction linkage stay, comprises a recess for receiving the tapered end of the bar which is attached to the openable vent of the window when the window is closed, and a pivotally mounted pawl member having a surface which defines an internal cam surface of the recess and which is adapted to engage and guide the tip of the bar as the window is closed and the tapered end enters the recess, the pawl pivoting so that when the tapered end is fully received in the recess the engagement between the tip of the bar and the inner edge of the pawl causes the outer edge of the pawl to bear against the inclined edge of the tapered end to hold the bar, and hence the window vent, firmly in the closed position.

Abstract: The present invention provides a hinge construction of two mounting plates and a substantially U-shaped center link which connects the axes of pivot of the two plates. The link and plates contain stop mechanisms which determine their respective limits of pivot. In addition, the hinge contains a means for restraining the rotation of only one of the mounting plates around its corresponding link arm to insure a pattern of motion that is always consistent, and allows for the hinge to be mounted with a very narrow gap between the members being joined. The hinge of the present invention can be variably constructed to conform to a number of alternative uses.

Abstract: A passenger door is connected to an aircraft fuselage by a hinge mechanism having an elongated goose-neck hinge member. One end of the hinge-member is pivotally connected to an idler crank arm that is pivotally connected to the fuselage. The other end of the goose-neck member is pivotally connected to the door. A guide arm connected to the door and carried by the idler crank arm controls door movement. An end of the guide arm has a pin that follows a groove in an "S"-shaped guide track. The shape of the track causes the guide arm to initially pivot and translate the door partially inwardly into the fuselage during opening movement, and then swing the door outwardly until it is parallel with the fuselage's outer surface.

Abstract: A hinge for mounting a false front for swinging between closed and open positions on a cabinet. The hinge includes first and second mounting brackets adapted to be secured to the false front and the cabinet, respectively. A first link has one end pivotably and slidably connected to the first bracket and an opposite end pivotably connected to the second bracket. A second link is pivotably connected between its ends to the first link, has one end pivotably connected to the first bracket, and has an opposite end pivotably and slidably connected to the second bracket. The hinge permits the false front and a tray thereon to be opened to an easily accessible position and enables the false front to be located between and closely adjacent to the countertop and the doors of the cabinet.

Abstract: A flush mounted hinge assembly for use in applications where the hinges are to be fully concealed and where the doors abut one another or an adjacent structural member, includes a cabinet mounted bracket, a door mounted bracket, and a housing pivotally mounted to the cabinet bracket.

Abstract: An improved recessing hinge mechanism for doors and the like is comprised of an anchor member slidably supporting an upper end of an arm of a selectively expandable stabilizer device having two cooperative arms pivotably joined to one another at their respective midpoints and pivotably supporting a lower end of the opposite arm, with the ends of the respective arms, opposite those attached to the anchor member, being slidably/pivotably attached to a support/pivot rod, which pivotably carries the pivot edges of a door. For a recessing operation, the door is pivoted about the rod from a closed position to an open position, parallel to the expanded stabilizer device and then linearly moved toward the anchor member, with the scissors-like stabilizer device closing to a minimum dimension so that the support rod stops adjacent to the anchor member. The inventive hinge mechanism provides a ratio of recess depth to door width which is greater than about 1:0.95.

Abstract: A suspension mechanism is provided for a hinged part, such as the engine hood of an agricultural tractor. The top of the engine hood is pivoted on an axle via a forked bearing. A follower on the bottom of the engine hood is guided in a track on the vehicle tractor frame. A support strut is provided at the front end of the hood. So long as the support strut is attached, the hood can pivot about the axle and the follower will move in the guide track on the frame, but the hood cannot be removed because the follower cannot leave the track. To remove the engine hood, the support strut is detached from the hood. The follower then can pivot entirely free of the track and the hood can simply be lifted off of the axle support. The support strut preferably is an outwardly biased pre-loaded gas pressurized spring reaching its shortest length somewhere between the open and closed positions of the hood. The spring then will bias the hood towards its open and closed positions.
