A door system includes a panel to translate along a normal path between an open position and a closed position in front of a doorway in a wall. The door system further includes a first track to support the panel from an upper portion of the panel, and a second track to extend along the normal path proximate a lower portion of the panel. The door system also includes a spring to urge the panel toward the second track to maintain the panel in the normal path.

A hinge permitting a gate to rotate approximately 180 degrees in either direction. The hinge includes first, second, third, and fourth hinge members and first, second, third, and fourth crossbars. The first, second, third, and fourth crossbars form an interpivoting connection with the first, second, third, and fourth hinge members.

The invention relates to a hinge for a swinging door, the hinge has at least one hinge axis element, a first hinge part and a second hinge part which are connected to one another in a hinge-like manner via the at least one hinge axis element, at least one latching arrangement, which comprises at least one latching means arranged at the second hinge part and comprising a latching body, and at least one latching recess arranged at the hinge axis element, wherein the latching means is configured such that the latching body engages in the latching recess in a latching position, and a clamping means for releasably fixing the hinge axis element to the first hinge part, wherein an angular position of the hinge axis element and the latching recess with respect to the first hinge part can be adjusted. The clamping means comprises at least one pair of clamping jaws for clamping the hinge axis element between these clamping jaws, wherein each of the clamping jaws comprises a clamping surface adapted to the contour of the hinge axis element.

Door assemblies, aircraft including door assemblies, and method for making door assemblies are provided. In one example, a door assembly includes a hinge subassembly and a door pivotally coupled to the hinge subassembly. The door has a channel disposed therein with a holding member disposed proximate a channel distal portion. A sliding member is movably disposed in the channel. An arm has a first portion pivotally coupled to a second hinge subassembly and a second portion pivotally coupled to the sliding member to move the sliding member as the door moves between a closed position and an open position. A stay member is coupled to the sliding member to move towards the holding member which holds the stay member in position when the door is moved to the open position to hold the door open.

A door is provided for restricting access through a doorway aperture. The door is defined at one or more peripheral faces, and is movable between a closed position in which the door is substantially aligned with the doorway aperture and an open position in which the door is pivoted from alignment with the doorway aperture to either side of the doorway aperture. The door has a door member defining a pair of major faces and at least one minor face at a peripheral edge of the major faces where a cross-section of at least one of the minor faces of the door member is configured to be substantially curved, so that in operation when the door is moved between its open position and closed position from either side of the doorway aperture, the minor faces remain proximate to at least one peripheral face of the doorway aperture.
