A gate comprises a spring-loaded hinge arrangement defining a rotational axis. A gate structure having a first support arm connected to a first end of the hinge arrangement is also provided. The gate structure is rotatable about the rotational axis. A spring-loaded hinge arrangement includes an outer hinge tube fixedly connectable to an adjacent structure and an inner hinge tube received in the outer hinge tube. The inner hinge tube has a first portion and a second portion movable with respect to each other, the second portion of the inner hinge tube being fixed with respect to the outer hinge tube and the first portion of the inner hinge tube being fixed with respect to the support arm.

A lavatory is provided which includes a plurality of walls including a first wall having a doorway, and an expandable door. The expandable door includes a main panel having dimensions that conform to the doorway and a main hinge connecting the main panel to the first wall. The lavatory further includes a latch. The main panel is configured to, in a deployed state, increase in at least one dimension to form a privacy barrier around an expansion zone located outside of the plurality of walls. The latch is configured to lock the expandable door in place in the deployed state.

In a preferred embodiment, a telescoping panel door for an aircraft compartment includes a first panel configured for hinged connection to a surface of a door frame, a second panel, and a linkage fixing a distance that the second panel can extend from the door frame, where the second panel is configured for connection to the door frame via the linkage. The door operates such that, in a closed position, the second panel is extended from an interior of the first panel, the first and second panels cooperate to completely cover an opening defined by the door frame, and the linkage is generally parallel to the plane defined by the door frame. In an open position, the second panel is retracted into the interior of the first panel by operation of the linkage and the first and second panels are nested to reduce a distanced spanned by the panels.

A telescoping door system includes a header that spans across a doorway. A trailing jamb and a lead jamb disposed a clear opening distance from the trailing jamb defines a clear opening of the doorway. A sidelite panel is coupled to the trailing jamb by at least one swing clear hinge; the swing clear hinge comprises a fixed gear portion intermeshed with a revolving gear portion. A slow slide panel and a fast slide panel move linearly within the header. The slow and fast slide panels are configured to create a first-sized opening when positioned in the header. The sidelite panel, the slow slide panel, and the fast slide panel are configured to pivot out of the header in a breakout position such that a trailing rail of the sidelite panel is disposed at least partially outside the clear opening and in front of the trailing jamb.

An uppermost cover member of a telescopic cover is fixed to a movable member (a saddle or a table), whereas a lowermost cover member of the telescopic cover is fixed to a stationary member (a pedestal or the saddle) of a machine tool, the stationary member being stopped with respect to a direction of movement of at least the movable member. Attached members, which project outwardly along the direction of movement from the telescopic cover, and which are attached by fastening members to the stationary member, are provided on the cover member. The telescopic cover is provided with a skirt, which is capable of sliding along the direction of movement with respect to the cover member, and which covers the attached members.

A dual function door acts as both a pocket door and a hinged swinging door. A first door panel is hingedly attached to a wall for swinging. A first header rail is attached to the top of the first door panel while a second header rail is attached to an appropriate surface at the same height as the first header rail. A second door panel has rollers that slide within the first header rail. The first door panel is positionable so that the first header rail and the second header rail align allowing the second door panel to also slide within the second header rail. The two header rails can be locked in the aligned position.

A telescopic mechanism and corresponding method for opening and closing sliding doors which allows obtaining a dimensional gain equal to the diameter of the pulleys including an intelligent control board, a motor, a system of pulley and belt linear guides which connect the panel A to Panel B, a lever system, arms, rotary union, shaft of rotation, which originate movements of extension and compression of a sliding structure comprising a chassis, Panel A and Panel B. The belt and pulley system includes a belt, a brake, wheels movable pulleys fixed to the chassis and static pulleys.
