Example aspects of a sliding door assembly, a sliding door system, and a method for using a sliding door system are disclosed. The sliding door assembly can comprise a track assembly defining a track surface and a slot; and a sliding door comprising a door body and a locking pin, the door body defining a left side and a right side opposite the left side, the locking pin proximate the right side, the locking pin removably engaging the slot, and the door body configured to pivot relative to the track assembly proximate the left side.

Example aspects of a sliding door assembly and a method for using a sliding door system are disclosed. The sliding door assembly can comprise a track assembly comprising a track assembly comprising a first track and a second track; a pivot assembly comprising a pivot carriage and a pivot mechanism engaging the pivot carriage, the pivot carriage configured to move along the first track; a locking carriage configured to move along the second track; and a sliding door comprising a door body and a locking pin, the locking pin removably engaging the locking carriage, and the door body configured to pivot at the pivot assembly relative to the track assembly.

A material control device having a housing, a material discharge door that has a left end, a right end, and a central axis and is adapted to be moved between a closed position and an open position, and a means for moving the material discharge door between the closed position and the open position. The means for moving the material discharge door between the closed position and the open position slidingly moves the material discharge door between the closed position and the open position. A method for controlling material discharge including providing a material control device and moving the material discharge door between the closed position and the open position.

In one example, a door apparatus is described, having a door leaf (102) part including a first door leaf portion (104a) and a second door leaf portion(104b), and having a pivot mechanism (106) defining a pivot axis connected to the first door leaf portion. The second door leaf portion is slidably movable with respect to the first door leaf portion between a first position, in which the door leaf part extends a first distance from the pivot axis, and a second position in which the door leaf part extends a second distance from the pivot axis, the first distance being larger than the second distance, and the pivot mechanism is to enable the door leaf part to pivot about the pivot axis when the second door leaf portion is in the second position.

A glass panel system including: a lower guide track and an upper guide track; and a first glass panel coupled to the lower guide track and the upper guide track in such a way that the first glass panel is movable along the lower guide track and the upper guide track in their longitudinal direction a guide track placed by the side of the first glass panel; and at least one locking element fastened to the first glass panel and configured to engage the guide track, along which the locking element is movable when the first glass panel is moving. When coupled to the guide track, the locking element supports the first glass panel and is configured to prevent any movement caused by bending of the first glass panel in either one lateral direction or two opposite lateral directions with respect to the guide track.

A door system includes a header having a guide rail that has a central portion having a notch. A panel hanger is slidably coupled to the header. A door panel has a handle end portion releasably coupled to the panel hanger and a pivot end portion pivotably coupled to the panel hanger. The panel hanger and the door panel slide in unison between a closed position and a fully open position along a longitudinal plane. An interlock plate is positioned to extend upwardly from the door panel, and has a downwardly extending guide slot that slidably receives the guide rail of the header. When the door panel is in the fully open position, the interlock plate is aligned with the notch of the guide rail of the header in a direction orthogonal to the longitudinal plane to facilitate a pivoting of the door panel away from the longitudinal plane.

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.

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 door assembly includes a door positionable within an opening defined in a wall, a bottom seal mounted to one of a bottom of the door and an underlying surface to generate a sealed interface at the underlying surface when the door is in a closed position, and a linkage operatively coupled to the door and actuatable to lift the door upwardly relative to the underlying surface and thereby separate the bottom seal from the other of the bottom of the door and the underlying surface.

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.
