The sliding door panels are slidably movable on the track between (1) a closed position wherein the sliding door panels are extended across the track, and (2) an open position wherein the sliding door panels are constructed and arranged to be in a compact, overlapping relationship with each other and the fixed door panel. The pivot mechanism is constructed and arranged to enable pivotal movement of the track with fixed door panel and the two sliding door panels mounted thereon about a pivot axis from a normal configuration to a breakaway configuration. The lock arrangement is constructed and arranged to releasably lock the track with respect to the track header to prevent pivotal movement of the track away from the normal configuration.

Abstract: A door package includes a door frame, a door, a handle, and a pivot plate. The frame has a top portion that includes tracks in which door panels can slide. The door includes two or more equal size door panels. The handle protrudes in a direction essentially perpendicular to the door panels and is connected to a latch mechanism for positively engaging with a corresponding latch mechanism in the door frame when the door is in a closed position. The pivot plate is attached to the floor and allows the door panels to pivot from a retracted position to a broken open position essentially perpendicular to the plane of the door. At least two of the door panels separate from each other while the door is pivoting from the retracted position to the broken open position, to allow the handle to be accommodated between the two door panels.

Abstract: Disclosed herein is a sliding window assembly having a security pane unit. The sliding window assembly includes a casing, a first security pane part, and a second security pane part. The casing has two or more rails and is open at a front thereof to an outside. The first security pane part has lattice strips, and slide grooves are formed on upper and lower portions of the first security pane part such that the first security pane part slides along an outer rail of the casing. The second security pane part has lattice strips, and is mounted to the same rail as the first security pane part at a central position of the casing in such a way as to be rotated via a rotary member. The secondary security pane part rotates about the rotary member to overlap the first security pane part and thus move leftwards and rightwards.

Abstract: A split glass rear side window assembly is separable along a generally horizontal longitudinally extending line into an upper glass member and a lower glass member separated by a seal carried by the lower glass member to receive the upper glass member when raised to cover the corresponding body opening. The upper and lower glass members are connected by side links that are pivotally connected to the lower glass member and slidable along the ends of the upper glass member to permit the upper and lower glass members to be stored in a parallel orientation spaced transversely within the limited storage area above the rear wheel well in the vehicle body. A spring device urges the lower glass member into a pre-selected storage pocket spaced transversely of the path of movement of the upper glass member. A rack and pinion apparatus vertically moves the window members.

Abstract: A sliding double hung window structure allows a window opening to be fully exposed to the external environment in an open position, with casements or windows being stored out of sight, and not in the opening. The window structure includes two casements or sashes balanced by suspended counterweights and guided by pins in guiding grooves in the two vertical sides of the sash. In the closed position, the casements are located in the same plane, one on top of the other. When fully opened, a breast cavity under the window receives the two casements in guiding grooves which communicate with guiding grooves in a vertical section running along the whole height of the window opening. A horizontal section connects the two vertical sections.

The deheader device comprises a frame attached to the coke drum, a bridge for supporting the first vessel cover and a second vessel cover, a central shaft having a distal end connected to the bridge and a thrust collar surrounding the shaft below the distal end. A lift assembly is attached to the frame for engaging the thrust collar to selectively raise and lower the bridge relative to the flange, and a rotational assembly is operatively connected to the central shaft for rotating the bridge to selectively align the first vessel cover or the second vessel cover above the flange during the delayed coking process.

Abstract: A garage doorway enclosure for mounting within the opening of a garage includes a primary guide track extending along a length of the top wall of a garage doorway. The enclosure further includes a plurality of door panels hingedly connected to each other. A guide element protrudes from each panel and is received in the primary guide track for slidable movement of the panels therealong. The panels are movable in an accordion-like manner between a closed position in which the panels cover the doorway and a folded position adjacent a side wall of the doorway. The guide element of the panel adjacent the side wall is slidable within a secondary guide track that is normal to the primary guide track such that the panels can be outwardly displaced from the doorway. The panels are pivotal from the displaced position to a storage position adjacent an outer wall of the garage.
