Abstract: Self-closing hinge for hanging the free leaf of a two-leaf corner cabinet door on the leaf that is hung on the carcase of the cabinet. The hinge has two members, one associated with each of the door leaves, which can turn by about 90.degree. on hinge pins passing through aligned bores provided in the area of the meeting edges of the door leaves, from the position at approximately right angles to one another when the corner cabinet is closed to a position in which they are aligned substantially parallel to one another when the corner cabinet is open. The hinge members are coupled together by an elongated, strap-like connecting element which is pivotally fastened to the one member and is mounted so as to be longitudinally displaceable on the other member. This strap-like connecting element acts on the one hand as a door stop which prevents the door leaves from turning relative to one another beyond a given angle, and on the other hand it forms part of a self-closing mechanism acting when the door is closed.

Abstract: The hinge is particularly adapted to permit a relatively thick door to be swung open without interference from the surrounding door mounting frame. A pair of arms pivotally connect the door to the frame, with the inner end of one of the arms being mounted on pin means having an axis about which the door rotates. Through the provision of various embodiments of connecting means and guide means, the pin means connecting the inner arm to the body travels in an arcuate, outward path when the door is opened, thereby moving the plane of the entire door outwardly to permit the room necessary to accommodate essentially full opening of the door. The pin means, during its arcuate movement, is guided by various forms of guide means to precisely define the arcuate path of travel.

Abstract: A double pivot hinge for vehicle doors includes a hinge arm pivotally interconnecting door and vehicle mounted hinge butts. A first and second latch means are alternately movable between latched and unlatched positions to either latch the hinge arm to the door mounted hinge butt for movement of the door and hinge arm as a unit to the 90.degree. open position or to latch the hinge arm to the vehicle mounted hinge butt for movement of the door relative to the hinge arm between 90.degree. and 180.degree. open positions. A detent means detents the first latch means in unlatched position during movement of the door between 90.degree. and 180.degree. open positions. The detent means is automatically released as the door moves from the 180.degree. position to a position immediately adjacent the 90.degree. open position to permit uninterrupted closing movement of the door.

The roof panel is connected at the rear edge through a hinge mechanism with the hoop member so that the roof panel can be retracted into the rear body section together with the hoop member. A locking member prevents a relative rotation of two links of the hinge mechanism with respect to each other when the hoop member is in the erected position and the roof panel is placed between the front windshield and the hoop member.

Abstract: An array of plate-like elements is retained by endless filaments looped on the elements to form migrating hinges between individual elements and other elements adjoining same. Grooves are formed in the surfaces of each plate, the grooves being in two groups, with the members of each group being mutually parallel, and the grooves of each surface being in overlying registration. The filaments lie within the grooves in a selected pattern, with filaments forming anchor points at plate sides at which the filament wraps around the side of the plate to enter a groove from the other group of grooves on the opposite side of the plate, and hinge points at plate sides where the filament passes from one plate to an abutting plate, proceeding from one surface to the opposite surface in doing so. Manipulation of the resulting array allows two such plates to rotate mutually about an axis defined by hinge points lying on their abutting sides.

Abstract: A composite array consists of plate-like elements or solid bodies interconnected by endless filaments. The front and rear surfaces of each element are provided with grooves, the grooves being divided in two groups, with grooves of each group running parallel with one another. The filaments lie within the grooves and are not attached to the elements. The filaments are arranged upon the elements so that each filament, upon reaching a lateral side of an element, is led into a groove on the opposite surface of the array. If the lateral side lies at the outmost edge of the array, the grooves are of different direction, while at lateral sides forming a line of contact, the grooves run in the same direction. On one or both surfaces of the elements, markings, numbers, letters, text or pattern elements may be found, for differentiating and determining the elements' positions.

Abstract: A sun visor for an automotive vehicle, having one main surface in which is defined a recess in which a housing is disposed over which a cover is pivotally mounted. One hinge pin for the cover is placed on the visor body. A second hinge pin for the cover is placed on the cover. A C-shaped strap joins the hinge pins. Each end region of the strap has two detent recesses.

Abstract: A document feeder is mounted for pivotal movement about a side edge portion of a copier/duplicator between a first position over an exposure station or platen of the copier/duplicator and a second position away from the exposure station so that individual documents sheets, books or the like can be manually placed directly on the exposure station for copying. As the feeder moves from its first position to its second position the feeder first pivots about one axis and then, subsequently, about a second axis offset further from the platen than the first axis. Thus the feeder is stepped away from the edge of the copier exposure station to provide a relatively large area that is available for receiving a book or large document on the exposure station for copying. A counterbalancing arrangement is provided for balancing the weight of the feeder as it moves between its two positions.

Abstract: Hinge structure for mounting a door to a cabinet for selective opening of the door from either side of the cabinet. The hinge structure includes a slide bar which is selectively positionable as a result of the opening of the door from either side of the cabinet to a thrown position. The structure includes locking elements for retaining the slide bar in the thrown position as long as the door remains pivoted open, thereby preventing the pivoting hinge structure from being removed from the cabinet. A second safety lock is provided for effectively positively preventing withdrawal of the pivoting hinge pin from the pivot slot while the door remains open from the opposite side of the cabinet. In one form, the structure for retaining the slide bar in the thrown position includes a pivotal member, and in another embodiment, the retaining structure is defined by a closely coiled spring.

Abstract: A pair of male and female hinge halves fabricated of extruded metal sections having complemental cross-sectional shapes so as to slidingly interfit and interhookingly engage with one another define a longitudinally extending through opening at one transverse side for the reception of a hinge pin, and interhooking means at the opposite side for interhooking engagement with the complementary shape of an extruded metal frame member of a solar collector frame or the like to be adjustably supported. The interhooking engagement between the hinge halves provides a limited movement fulcrum between the two transverse sides serving to clamp the opposite side interhooking means in secure frictional abutment with the extruded metal frame member when the hinge pin is force-fitted into its through opening.

Abstract: A new and novel concealed door hinge is disclosed and includes three pivot points, all of which are hidden when the door is closed. The device includes a substantially right angle interior leaf secured to the cabinet and a cup-like external leaf secured within a recess in the door. A forcing member is pivotally connected to one of the surfaces of the interior leaf and a pivoting member is pivotally connected to another surface of the internal leaf and to the external leaf. In one embodiment of the invention, when closing the door, a cam-like structure within the external leaf moves the forcing member to urge the pivoting member toward the door opening and, consequently, causes the entire hinge assembly to close. In another embodiment of the invention, the pivot point between the forcing member and the interior leaf is slidingly positioned with respect to the interior leaf. This embodiment also includes an axle which interconnects the forcing member and the pivoting member.
