Abstract: A hingeless door system for a pressure vessel; especially, aeronautic and astronautic crafts. The door system has the following major components: a contour in a pressure vessel wall, a doorway opening, a seal, an upper track, a lower track and a door. The door translocates laterally along the tracks from an open position to a closing position and moves radailly along the tracks to a sealing position against the contour which closes the door opening. The problem solved by the invention is to reduce weight, operational volume and complexity and increase durability of a door system for pressure vessel.

Abstract: An internal swivel door for an aircraft compartment. A door frame for entering the compartment includes a horizontal element and at least one door leaf which is mounted inside the door frame wherein the door leaf is turned about a vertical door rotational axis. The vertical door rotational axis is moved in parallel along a predetermined local curve. In order to take up less space during opening and closing of the door and to be able to operate the door with the least possible force, the door has a rotary sliding joint between the door leaf and the horizontal element. The door leaf has a rotational movement about a momentary rotational axis running through the rotary sliding joint wherein the momentary rotational axis is moved in parallel both in relation to the horizontal element and the door leaf.

Abstract: An oven door hinge comprises a pair of engaging devices at respective sides of the door, having a recess at the middle of each engaging device. A plural lugs are formed inside of the door for receiving covers to form a gap. The top portion of the engaging device has a through hole for receiving a connecting unit. The connecting unit has a pin extending through a spring and into the gap of the door with a portion extending into the recess. The oven has a pair of posts extending from respective sides thereof. When mounting the door onto the oven, the pin is urged by the spring to retract so that the door may be moved to the gap and the recesses of the engaging devices will be engaged with the posts, respectively, and the pin extends into the recesses to secure the door on the oven.

Abstract: An operator for a jalousie window includes a linkage with two toggle joints. The toggle joints assist in locking the window in its fully opened or fully closed position. The toggle joints of the operator are actuated by an actuating lever which is mounted to the window frame of the jalousie window so as to provide a mechanical advantage to operation of the jalousie window. The mechanical advantage afforded by the operator allows relatively heavy jalousie window louvers and associated moving components to be actuated by means of a tolerable range of actuating forces. The operating linkage is equipped with brakes which permit the louvers of the window to be maintained in any number of fixed orientations between the fully opened and fully closed position of the window.

Abstract: A closure assembly is provided including a track and a slidable and pivotable closure member. The closure member is engaged with the track proximate first and second pivots adjacent the pivotable end of the member, the first and second pivots being interconnected by a multiple segment shaft (for example at least two portions) (for example telescoping) which provides for accurate installation, retention, removal, adjustment and alignment of the first and second pivots in a substantially parallel line for pivotally supporting the closure member so that it may be safely and securely pivoted away from the closure assembly. Improvements to the abovementioned structure are also provided.

Abstract: A sash of a hopper window is linked to a shoe which engages a track in constant resistance to travel along the track such that the sash can be tilted by hand to any angle from the track within a predetermined range of angles, and will remain at the angle unaided.

The duplex hinge assembly (10 or 10') includes dual hinge mechanisms (20) and a latching mechanism (50) to deactivate the duplex hinge mechanism (10) with the access panel (100) in the closed position. The dual hinge mechanisms (20) include a primary mounting bracket (22) secured in combination with the airframe (130), a secondary mounting bracket (24) secured in combination with the access panel (100), and an interconnecting member (26) having a straight segment (30), an arcuate segment (32), and a protective flat segment (34).

Abstract: A side-hinged, 180 degrees rotatable window, having a window casement which is pivotably mounted about a first vertical axis and about a second vertical axis relative to a window frame. The window casement is supported hanging at its one upper corner via a head portion (27) on a pivot pin (26) in a carriage (25), which is displaceable in a horizontal guide (16) in the window frame. The window casement is pivotably mounted at its center axis at the one end of an upper and a lower support or pivot arm, the opposite end of which is pivotably mounted about a third vertical axis in the window frame. The carriage (25) is designed with a part-spherical seat (25') for an equivalent part spherical portion of the support head (27) of the first pivot pin.

Abstract: A vehicle hood-mounting arrangement includes a hinge member and an actuator for rotating the hinge member about a first axis of rotation. The hinge member is attached to a vehicle hood at a second axis of rotation. During rotation between a fully opened position and a fully closed position, the vehicle hood translates horizontally and forwardly. Preferably, the vehicle hood mounting arrangement also includes an H-shaped linkage for supporting and stabilizing the vehicle hood.

Abstract: A door which can be automatically opened and closed can have an additional releasable connection for allowing the door panels to be manually opened by disengaging the door panels from the device for automatically opening and closing the doors. In particular, two-panel doors which execute a combined sliding and rotational motion around a vertical axis of rotation during the closing and opening motion can be configured with such a device to make it possible to use the doors in evacuation and emergency routes, i.e. routes in which a manual force can be applied from inside to open the door panels. Further, so that the door does not remain open, there can also preferably be switches or circuits in the construction which indicate that a manual opening of the door panels has occurred, in which case an electronic signal can be generated to place the drive device in motion, to thereby automatically restore the connection between the door panels and the drive system.

Abstract: A hinge structure for supporting a window sash on a window frame. The hinge structure includes sash arms secured to opposite sash sides, and a shaft having gears fixed to its ends and supported by tracks for longitudinal movement along opposite sides of the frame. The gears engage racks on each of the tracks. The sash arms are carried with the shaft in its longitudinal movement along the tracks.

Abstract: The closure device is suitable for use as a lateral door or a back door of a passenger vehicle. It comprises a closure member movable between a closure position on a frame and a fully open position. The linkage connecting the closure member to a body provided with the frame has first arms and second arms. The first arms are pivotally mounted on the body for rotation about a horizontal axis and are pivotally mounted at their other end on a closure member about another axis parallel to the first axis. The second arms each have an end mounted on the body for pivotal movement about a horizontal axis parallel to the other axis and another end pivotally mounted on the closure member for rotation about an axis parallel to the other axis. The second arms are telescopic and have a retracted condition in which they have a first length and an expanded condition in which they have a second length greater than the first length.

Abstract: A coin-operated latch mechanism for a newspaper rack includes a coin-receiving mechanism into which coins are deposited. A coin-return mechanism is provided which, when depressed, swings the coin-receiving mechanism to a position in which the outlets of the coin slots overly a coin-return diverter. The coin-return diverter is normally disposed in a coin return mode and is moved to a coin retention position in response to the opening of a door of the rack. A key-actuated wall of the rack is mounted on hinges which permit a simplified removal of the wall from the rack. The key-actuated wall includes a latch which enables the wall to be closed and relatched without the use of a key.
