Abstract: I designed the “Classic Step Store Gate”, It does not use a pivot post. Classic, Step Store Gate uses my special hinge made by modifying a strap hinge. “Classic” is different in design; “Classic” has a rounded firm handrail across the top, and can help prevent a fall at the steps. It is used at steps going up or down. The opening end of the gate is lifted to open toward steps or into the room. The “Classic Step Store Gate”, has an attractive clean look from the front view, and an interesting mechanical view from the back. The gate can be stored along the wall on the steps.

Abstract: A mechanism for the installment of a door or other similar closure having a rotational-sliding movement, of the type comprising the following elements to associate to a shutter: first pivot means defining a first vertical axis for the pivoting of a shutter, in a substantially central region thereof, to translation means arranged so as to slide in a corresponding guide associated to the upper strut of a frame of a door; second pivot means with an axis parallel to the axis of the first pivot means, for the pivoting of two arms, a first upper one and a second lower one, that are both pivoted with one of their ends to the frame of the door or closure in proximity to a jamb to define a second rotation axis, and have the opposite ends reciprocally rigidly coupled by means of a rod, defining a third rotation axis interposed between the first axis and the second axis, passing through the shutter in the direction of the height thereof.

Abstract: An entry assembly includes a frame and a gate. The frame has a first side and a second side. The gate is connected to the frame. The gate defines a demarcation between the first side and the second side of the frame. The gate is pivotable about the frame along at least two axes of rotation. Each axis of rotation intersects at least one of the at least two axes of rotation.

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: A preferred embodiment of a self-locking door assembly includes a door whose hinged-side connects to one side of a door frame by at least one hinge having two pivot joints. One of the pivot joints is mounted to the door frame and the other is mounted to the inside of the door. The free end of the door carries a latch member which engages an underside of the opposite side of the door frame when the door is partially or fully closed. After the latch engages the frame, forcing the hinged side of the door closed causes the hinge to toggle, holding the door closed under force and takes up play in the pivot joints and/or latch. For security, the pivot joints and latch are concealed when the door assembly is closed.

Abstract: A bidirectional opening/closing door unit and a refrigerator having the same. The door unit is provided at a side of a body of the refrigerator to open or close the body. The body includes hinges protruding from left and right sides of the body to be coupled with the door unit. The door unit includes a door and an opening/closing device provided at a side of the door. The opening/closing device includes a pair of opening/closing structures detachable to the respective hinges, and an operative connector to be operatively connected to one of the opening/closing structures to limit operation of the other opening/closing structure. With this configuration, the operative connector can achieve smooth movements and maintain a high durability in spite of frequency opening/closing operations and long time use of the door.

Abstract: An apparatus for attaching a door to a passenger vehicle body having a lift arm and a hinge assembly. The lift arm rotatably connects the door to the vehicle body. The lift arm imparts upward rotational movement to the door relative to the vehicle body as upward pressure is applied to the arm. The hinge assembly allows the door to open horizontally about a pair of hinges connected to the hinge assembly. A stop pin assembly dictates whether the door can be opened vertically or horizontally.

Abstract: Articulation device for an aircraft door panel and an aircraft door integrating such a device. An aircraft door panel is articulated on the jamb by a device (20) that defines an approximately elliptical opening and closing trajectory, in which the major axis is approximately perpendicular to the panel. The device (20) comprises in particular a main arm (30), a secondary arm (32) articulated at the end of the main arm and a control lever (34) connecting the secondary arm (32) to the jamb, by articulation axes (A4, A5) close to the articulation axes of the main arm (30) on the jamb and the secondary arm (32) on the main arm. This arrangement makes it possible to fit a more voluminous emergency exit chute into the door panel.

Abstract: A device for opening a passenger door of an aircraft includes a supporting arm connected movably to the fuselage frame, a wishbone connecting the support arm to the passenger door, a first journal rotatably connecting the wishbone to the support arm, and a lifting mechanism.

Abstract: A swing away manway assembly for a tubular fluid conveying system having a manway opening in a first horizontal plane, the assembly including a cover disposed in a second parallel horizontal plane. The manway cover includes a circumferential sealing means for continuous sealing of the manway opening. The cover is provided with latch means for alternatively engaging and releasing the sealing means. Swing away means is secured to the cover in a plane perpendicular to the first and second horizontal planes of the cover and opening. The swing away means is adapted to facilitate swinging movement of the cover in a horizontal plane upon release of the sealing means. The swing away means includes biasing means for cooperation with the latch means in urging sealing engagement of the cover with the opening, and cam means for limited vertical movement of the cover during horizontal rotation thereof.
