Abstract: A door installation arrangement adapted to widely open a door of an automotive vehicle. The door installation arrangement is comprised of a double hinge member which has a first end section hingedly connected to a door body side, and a second end section hingedly connected to a vehicle body side. A hinge trim is disposed separate from the double hinge member to decoratively cover the double hinge member. The hinge trim is hingedly connected at its front end within the vehicle body side through a sub-double hinge member and at its rear end with a door trim through a hinge member.

Abstract: Disclosed is a handcuff device for restraining the wrists of a detainee. The device comprises a pair of handcuff members and a link member of unitary construction. Each of the handcuff members have one or more integrally formed mounting posts. The link member is configured to hingedly interconnect the handcuff members about the posts. The unitary construction of the link member, combined with the integrally formed posts of the handcuff members, provide a handcuff device which is strong and durable and which does not require the use of multiple components, such as a pivot pin, and substantially limits the movement of the detainees hands.

Abstract: A hinge having at least three leaves pivotally joined along edges of the leaves and adapted for attachment to two members to be pivotally connected with at least one member secured to a pair of the leaves which are mutally inclined in such a way that each leaf of the pair resists bending of the other leaf of the pair. A present best mode embodiment of the hinge has four leaves and is designed primarily for use on so-called ultralight airplanes as aileron, rudder, and elevator hinges which are immune to fatigue stress failure. Another hinge embodiment is designed for use as a door hinge and has only three leaves.

Abstract: A blocking mechanism for the top and rear lid of a motor vehicle with a convertible top, in which the ends of a cable or of a rod are secured at a distance from the respective lid axis at the top and rear lid and at a pivot part supportable at the body. Additionally, an abutment is formed at one pivot part which, during the opening of the coordinated top or rear lid, acts on the second pivot part. As a result thereof, either an opening of the top or rear lid coordinated to the second pivot part is prevented or, during the opening of the top or rear lid, the respectively other top or rear lid is closed.

Abstract: Convertible top apparatus for midengine automobiles, such as the Pontiac Fiero and Toyota MR2, which have a far forwardly extending rear deck lid for accessing the engine, comprises a foldable frame assembly, a pliable top covering for the frame and means for pivotally mounting the frame assembly to the automobile body, for example, after the factory installed hard top is removed, forwardly of the forward end of the rear deck lid. The frame assembly is configured so that rearward portions of the top extend rearwardly over the deck lid when the top is up, portions of the frame assembly stacking on top of forward regions of the rear deck when the top is down. The frame mounting means include mounting brackets fixed to the automobile and hinge members pivotally mounted to the brackets and to which both the deck lid and top frame assembly are connected. The brackets and hinge members are configured so that with the top up, opening the deck lid also pivots up rearward portions of the top.

Abstract: A seal for a piano hinge for preventing passage of electromagnetic energy through the hinge; said seal comprising a first sealing member of conductive material comprising a connecting section for attachment to and for electrical contact with one hinge leaf and an arcuate section shaped to fit over the hinge knuckles, and a second sealing member of conductive material comprising a connecting section for attachment to and for electrical contact with another hinge leaf and an arcuate section for overlapping and for making electrical contact with the arcuate section of the first sealing member. Preferably the sealing members are of hard copper alloy. Another embodiment includes a detachable sealed hinge assembly wherein the hinge includes three leaves; an attached leaf, an insertion leaf, and an attachable leaf.

Abstract: A joint for use in a collapsible chair has a main component with a stub which is connectable with the seat of the chair and is integral with a housing for the flat shorter arms of first and second two-armed levers each of which is pivotally secured to the housing by a rivet. The longer arm of the first lever is connected to the back and the longer arm of the second lever is connected to the rear foot of the chair. The shorter arms of the levers are coupled to the respective end portions of a link by two pivot members whose axes are parallel to the axes of the rivets. The levers are pivotable relative to the main component between (a) operative positions in which the chair is erected and the axis of the rivet for the first or second lever is disposed in the common plane of the two pivot members, and (b) inoperative positions in which the chair is collapsed and the longer arms of the levers are adjacent and parallel to the stub of the main component.

Abstract: A box, such as may be used to store audio disks computer floppy disks or the like, in which the box opens up into a fan-like shape so that the articles stored therein can readily be identified. A box body is constituted by a back plate, a bottom plate and a left and a right side plate. A front plate section, constituted by a front plate, is pivoted at its lower end on the bottom plate. Left and right wing plates, which extend from the respective opposite sides of the front plate, contact the left and right side plates. A cover plate is formed by a top plate having a collar extending therefrom with the cover section being swingably pivoted on the box body.

Abstract: A case for holding floppy discs or other flat articles comprises a boxlike body and a cover, which is hinged to said body and can be turned up from the same. A compartment is defined by the inside surface of said cover and by a lid, which is hinged to the cover near its rear edge. To ensure that an opening movement of the cover will open also the lid, the latter is provided on its sides with cam follower pins, which engage respective cam tracks provided in the body. Each cam track comprises a portion which corresponds to an arc of a circle entered on the hinge axis on which the cover is hinged to the body. That cam track portion is succeeded in the direction of the opening movement of the cover by a cam track end portion, which deviates outwardly from said circle.

Abstract: Connectors for joining struts used to form geodesic domes have first and second sets of semicylindrical portions located alternately on opposite sides of the longitudinal centerline of the connector. In the assembled joint, the first and second sets of adjacent connectors are interleaved and secured by pins or bolts forming hinge-like interconnections.

Abstract: A hinge joint for joining hollow panels utilized for covering swimming pools includes two leaf-like connecting parts with overlapped portions each having an axial bore to receive a hinge pin. Each connecting part has a supporting bar hooked into a bore provided in the outside face of the cover panel and extended into the cavity formed in the hollow panel.

Abstract: A hood hinge mechanism includes upper and lower brackets interconnected by pivoted links. An auxiliary hinge member is pivoted to the upper bracket and secured to the hood. The lower bracket is secured to the body. The upper hinge bracket and auxiliary hinge member are releasably secured to each other and normally move together as the hood moves between closed and partially open positions. When the auxiliary hinge member is released from the upper hinge bracket, the hood can be moved to various further open positions.

Abstract: A detachable hinge assembly for a toilet, which pivotally connects a toilet seat and cover to a toilet bowl, wherein most of the hinge assembly, while remaining pivotally connected to the seat and cover, may be detached from the toilet bowl, leaving only a pair of mounting studs, which are part of the hinge assembly, attached to the toilet bowl.

Abstract: A cabinet which contains an appliance such as a refrigerator is provided with novel hinges having one member secured to the body of the appliance and the other member adapted to carry both the door of the appliance and the door of the cabinet for simultaneous operation. The hinge members are interconnected in a known manner by means of connecting links pivotally mounted at each end to the respective member. A spring may be incorporated in each hinge for biassing the doors into the closed position.
