A guide pin support system may include: a first support plate; a second support plate pivotally attached to the first support plate; a first guide pin supported by the first support plate; a second guide pin supported by the second support plate and the second guide pin pivotable with respect to the first guide pin.

A sliding door system and method is used in an enclosure that defines an inner area shielded against a High-Altitude Electromagnetic Pulse (HEMP). The HEMP shielded sliding door system includes an RF shielding door frame, an RF shielding door leaf mounted within an mechanical door leaf frame, a mechanical insertion and retraction assembly attached to both the mechanical door leaf frame and RF shielding door leaf and that operates to extend and retract the RF shielding door leaf into and out of the RF shielding door frame, a drive tube assembly operable to interact with and open and close mechanical door leaf frame (along with RF shielding door leaf) in a sliding motion, and a control assembly, including motor and an air regulator assembly. HEMP shielding air seals are activated when the RF shielding door leaf is inserted into the RF shielding door frame.

A fenestration unit is disclosed. In various examples, the fenestration unit includes a plurality of panels, including first and second panels. In some examples, one or more of the plurality of panels is configured to slide relative to a frame of the fenestration unit to provide an opening in the fenestration unit. In various examples, each of the first and second panels are also configured to be pivoted relative to the frame such that the first and second panels can be hinged or otherwise pivoted open to increase the size of the opening in the fenestration unit.

A leafless joint apparatus that couples a housing structure to a hatch structure such as a cover or door. Similar to previous hinge apparatuses, the leafless joint apparatus can include a knuckle and a pintel or pin to facilitate pivot operations (e.g., the cover pivoting open). However, the leafless joint apparatus does not rely on leafs that attach by means of fasteners (e.g., screws or the like) and therefore can facilitate sliding operations (e.g., the cover can slide open). Thus, the leafless joint apparatus can facilitate access to an interior of the housing structure by way repositioning the hatch structure via a pivot or hinging operation or via a sliding operation that can partially or fully expose the interior of the housing structure and even, if desired, slide entirely off, decoupling from the housing structure.

A door includes a panel assembly including a leading panel and a trailing panel. The leading panel is to be in substantially coplanar alignment with the trailing panel when the panel assembly is in a normal configuration. The leading panel is to be angularly displaced out of coplanar alignment with the trailing panel when the panel assembly is in a dislodged configuration. The door further includes a tension member to connect the leading panel to the trailing panel. The tension member is to resiliently urge the leading panel and the trailing panel toward each other in a horizontal direction. The tension member is to resiliently urge the panel assembly toward the normal configuration when the panel assembly is in the dislodged configuration.

A passage gate for allowing or preventing people to enter or to exit a passage area comprising a base portion (110) and a panel portion (120) is provided. The passage gate (100) is configured to be driven in a first operation mode and a second operation mode. When the passage gate (100) is driven in the first operation mode the panel portion (120) is slidable relative the base portion (110) between a first open position, allowing people to pass, and a closed position preventing people from passing through the passage gate (100). When the passage gate (100) is driven in the second operation mode the base portion (110) is rotatable between the closed position and a second open position for achieving a larger passage area.

Conventional UPVC windows have casements which are pivotable and movable in a limited manner relative to the frame. It is desirable to be to move all the casements such that substantially the entire the frame is opened. This is achieved by providing a window (10) comprising a frame (20) including a head (22), a sill (24), the window further comprising at least first and second casements, wherein the first casement includes hinges (50) for rotating it relative to the frame, the hinges being movable relative to the frame along channels (120) provided in the sill and head such that the first casement is slidable within the frame, the first casement also including at least one guide (52) located on the upper and/or lower surface of the first casement distal from the hinges and movable within the respective head or sill channel as the first casement slides relative to the frame, the said at least one guide disengagable from the respective head or sill channel allowing the at least one guide to pass out of the respective channel thus allowing the first casement to be opened relative to the frame, the sill including a runner (140) on which the casement is slidable. In this way the first casement may be stacked adjacent the second casement at one end of the window frame after both have been pivoted open.

A sliding door assembly includes a track assembly comprising an inner track component, and outer track component, and a central track component, the inner track component and the central track component defining an inner track, the outer track component and the central track component defining an outer track; a pivot assembly engaged with and movable along the inner track; a sliding door pivotably mounted to the pivot assembly; and a locking pin coupled to the sliding door and movable between an extended configuration and a retracted configuration, wherein, in the extended configuration, the locking pin is engaged with and movable along the outer track.

A folding sliding door that uses a track and exposed rotating rollers attached to a series of door panels whereby the door panels can fold while the exposed rotating rollers roll along the track, thereby permitting the appearance of a sliding barn door.
