Abstract: A displayable appendix linked to the structure of a space vehicle movable about an articulation axis from a stored position along the structure of the space vehicle to a display position by a control mechanism with abutments on the appendix and on the structure of the space vehicle so distributed and located as to prevent warping or distortion of the articulation axis and the control mechanism by exerting upon the appendix bending prestresses which are reduced near the articulation axis to a pure prestress torque tending to cause the appendix to move to the display position and temporary forces obtained from use of the abutments to hold the displayable appendix in the stored position during launch of the space vehicle.

Abstract: The invention resides in an outside door handle assembly which comprises a door handle pivotably mounted on a door of an automotive vehicle; and a door latch operating rod having an end portion which is pivotably attached to an extension of said door handle after assemblying thereto. A pair of finger projections are made integral with the door handle arm. There is provided a channel-shaped metal bracket fixedly attached to a door panel and pivotably mounting said finger projections. An inclined groove formed on each of the finger projections generally opening towards the two limbs of the bracket and adapted for receiving partially these limbs when said door handle arm has been brought into its upper service position, thereby torsional deflexion of the bracket as liably occuring during the door-opening operation being prevented effectively.

Abstract: The present invention relates to a vehicle seat, particularly for airplanes and buses. The seat has a support with an adjacent divider having a bore therethrough. A hollow pin has an end section detachably engaged in the bore of the adjacent seat divider. A back rest is mounted at one of its sides on the hollow pin. A connecting body is arranged in the bore of the seat divider and has a longitudinally threaded bore therethrough. A threaded bolt passes through the hollow pin and engages with the threaded bore through the connecting body. A folding table support is mounted on the threaded bolt for pivoting movement thereabout. A stop projects from the hollow pin and limits the pivot movement of the folding table support.

Abstract: A detachable hinge assembly consisting of a generally L-shaped member secured to a movable structure and a second generally z-shaped member secured to a frame, the L-shaped member having openings in each of its leg portions through which leg portions the Z-shaped members extend. The relationship between the openings and leg portions is designed so that the upward and sideward member of the L-shaped member relative to the z-shaped member is restricted, while permitting the L-shaped member to be pivoted relative to the z-shaped member, so that the movable structure to which the L-shaped member is attached can be disengaged from the z-shaped member without the use of tools.

Abstract: A hinge having first and second elongated hinge members. The two hinge members rotate one within the other between open and closed positions. The hinge members are constructed to avoid any longitudinal gaps between the hinge members in either the open or closed positions.

Abstract: A hinge bracket-mounting plate assembly comprises a detent nose carried at the end of a spring-loaded detent lever and also has a detent opening or detent abutment. When the hinge bracket has been inserted into a track of the mounting plate and pushed along the latter, the detent nose snaps into the detent opening or against the detent abutment to releasably lock the parts together. The extent to which the hinge bracket can be pushed along the mounting plate is limited by a stop, which becomes effective when the detent nose snaps or after it has snapped into the detent opening or against the detent abutment. To eliminate backlash, the detent nose has an engaging side face, which bears on an edge or surface of the detent opening or detent abutment to force a stop carried by the hinge bracket or the mounting plate into backlash-free engagement with a complementary stop carried by the other part.

Abstract: A door-operating mechanism is disclosed which is particularly suited for use with hingedly mounted swinging glass doors of a refrigerated display cabinet. The door operating mechanism includes an extensible gas spring biased toward an extended condition, and a linkage arrangement operatively interconnecting the gas spring with the door. A portion of the gas spring is movably disposed within a slot defined by the linkage arrangement such that in one position of the gas spring the door is biased toward its closed position, and in another position of the gas spring the door may be maintained in an opened position such as for stocking or maintenance of the display cabinet.

Abstract: A safety device for a photocopy machine implemented by inserting a core bar rotatably into a fixed member, while the core bar rotatably supports a rotation member. A spiral spring is secured between the core bar and the rotation member, preventing the rotation of the core bar. A stopper member is placed between the core bar and the rotation member, the stopper member's position being maintained with the aid of a tension coil spring. If the spiral spring breaks, the stopper member shifts in a direction adapted to insert a projection of the stopper member into a detent on the rotation member and thereby prevent the falling of the rotation member.

Abstract: A hold-open mechanism is disclosed which is particularly suitable for use on a self-closing door assembly for a refrigerated display cabinet. The hold-open mechanism includes a stop plate carried by the hinged door, and a hold-open spring mounted on the door frame which supports the door. In one embodiment, the hold-open spring is selectively positionable so as to accommodate normal swinging movement of the door in one position, and is adapted to releasably engage and retain the stop plate on the door in a second position so that the door is maintained opened. In another embodiment, the hold-open mechanism automatically operates to releasably retain the door in its fully opened position whenever the door is moved to that position.

Abstract: A door hinge for furniture is made up of a box-like part designed to be set within or inset into a recess in a door from its back side, and has a spring-powered or pressed bolt for acting on a cam face at the end of an L-like support arm. The arm is fixed to the body or frame of a piece of furniture so that in one (or two) positions where the cam face has an inwardly offset of cut-out portion, the bolt will be responsible for a detent effect to keep the door in a shut position or in shut and or open positions. The L-like support arm is fixed to the body of the piece of furniture by way of a base or mounting plate having a guiding mounting ledge for cooperating with one leg of the support arm. The one leg portion has a wedging face and is responsible for guiding the support arm parallel to itself for changing the height of the arm. The arm is mounted on the base plate in position for normal use by a metal screw or the like.
