Abstract: A glass cover for an enclosure is mounted over an opening in the enclosure by a pair of recessed hinges, each of which includes a hinged body. There are two slots in each hinged body. Each hinged body is positioned within a recess in the enclosure wall. The hinge also includes a frictional member positioned in one of the slots in the hinged body, and a cover holder. Two pins couple the cover holder to the hinge body. One of the pins is coupled to the friction member; this pin passes through one of the slots into a socket in the friction member. The other pin is positioned within the other slot. The frictional member engages a portion of the hinged body defining the perimeter of the slot in which it is disposed. As the cover is raised and lowered, the frictional member rides along this slot. The frictional forces between the side walls of the slot and the friction member are such that the cover remains stationary when the person lifting the cover releases his or her grip.
Abstract: A shock absorbing fallfront bracket of the type having rigid hinged-together links diagonally supporting the fallfront panel in its open position and folding into the cabinet in closed position, and also including a third spring loaded link extending from the mutual hinge of the linked pair and to the cabinet to resiliently resist the full opening of the panel, and to fold, when closed, fully into the cabinet along with the supporting linked pair.
Abstract: A mounting device for connecting a lid covering a dust collecting space in a vacuum cleaner to the housing of the vacuum cleaner, which includes two spaced pivotable arms each connected to the lid and supported on an axle slidably positioned in an oblong opening formed in the housing.
Abstract: The hinge for mounting a closure panel on a vehicle body includes a body bracket mounted on the vehicle body and having a cam surface and an elongated cam slot. A panel bracket is mounted on the closure panel and has a cam follower portion slidably bearing on the cam surface of the body bracket to define a first cam arrangement. A torsion bar has one end nonrotatably mounted on the vehicle body and the other end nonrotatably mounted on the panel bracket so that the torsion bar torsionally biases the panel bracket and closure panel to a normal pivotal position relative the vehicle body. The portion of the torsion bar mounted on a panel bracket extends slidably through the cam slot of the body bracket to define a second cam arrangement. The first and second cam arrangements are arranged relative one another whereby upon pivotal opening movement of the closure panel, the closure panel is bodily shifted to avoid interference of the closure panel with the vehicle body.
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.
Abstract: A hinge structure is disclosed which is especially suited for use in a double pivot hinge connecting together two panels for pivotal movement in their common plane. Such panels may be the frame members of a folding chair. In each panel, an aperture is provided having a partly circular socket portion and having two opposed abutment surfaces lying transverse to a circular arc centered on the socket portion, and a bushing is located in each socket portion. The two panels are connected by a rod having its opposite ends forming shaft portions rotatable within the bushings and having a lever portion extending along the outer surfaces of the panels and forming a connection between the panels, and having intermediate portions connecting the lever and shaft portions and configured to contact the abutment surfaces to limit pivotal movement of the rod relative to the two panels.
Abstract: A door construction for covering control knobs or the like upon the front panel of the electronic equipment. Hinge members rigidly coupled to the door member have rotatably mounted thereon guide rollers which are disposed into corresponding guide grooves. Each guide groove has a linear guide portion and an enlarged circular guide groove at the front end thereof. Each of the guide rollers has a substantially oblong portion and a coaxial cylindrical portion wherein the door is movable only horizontally when the oblong portions are engaged with the linear grooves and the door is only rotatable when the circular portions are engaged with the enlarged circular grooves.
