Abstract: A universal sliding door system that is configured to facilitate installation in either a slide right to open (SRO) orientation or a slide left to open (SLO) orientation. In some embodiments, a track is attached to a header by a pivot connector that allows the track to be pivoted up or down so that the track can be easily oriented at an appropriate angle for the desired opening orientation. The header and track may also each include a first set of openings configured to allow the track to be easily installed in a SRO orientation and a second set of openings configured to allow the track to be easily installed in a SLO orientation. Other components of the door system, such as the door and the vertical casing members may also include features configured to allow the components to easily be installed in either opening orientation.

Abstract: A sliding door system comprises a door made of a glass panel. Roller units are connected to the door and project from a plane of the door. A structural transom has a glass panel body with main surfaces of the glass panel body positioned generally vertically. The glass panel body has at least one slot defined therein having a lower edge surface and an upper edge surface. The slot has a height for receiving a portion of the roller units between the lower edge surface and the upper edge surface, and a length for allowing a translation of the door to open and close an opening by movement of the roller units in the slot.

Abstract: A non-hanging sliding door system includes a sliding door having an upper roller assembly disposed atop a portion of the door's frame, a channeled upper track configured to receive rollers of the upper roller assembly, a lower wheel assembly disposed at a bottom portion of the frame, and a guiding roller assembly. The lower wheel assembly includes a vertical spine having a transverse shaft, and a pair of sliding wheels that are rotatably coupled to the transverse shaft and are in direct contact with the ground without the need for a lower track. The guiding roller assembly includes one or more rollers that roll in frictional contact with the walls of a channel defined in the underside of the frame. The guiding roller assembly may be coupled either directly to the ground/floor below the door, or to a wall parallel to the door using a mounting bracket.

Abstract: A system and device of sliding panels contained in a frame that allows the panels to be stored in one part of the frame and moved to different parts when in use. Panels slide along horizontally and vertically within the frame so that various alternate placement of panels can close the frame, or create openings of different sizes, shapes and locations within the frame. The panels within this system can be used to enclose a vehicle or structure; to protect the interior of the structure and its occupants from inclement weather; miscellaneous intrusions such as insects, dirt and the like; as well as from firearm, chemical, and biological assault. The panels can be readily changed to accommodate to these needs by substituting a panel made of an appropriate material. If the panel system is used in modular form, even panel walls of buildings can be rapidly constructed. The device also can be used for a multi-panel display device.

Abstract: An aircraft door is slidable along a door path between open and closed positions. The door is guided by one or more tracks. Riders carried by the door are engaged to the tracks. Each rider includes a roller held for rotation about a roller axis which is fixed relative to the door. Each roller axis extends generally horizontally and generally transverse to the track. Each track includes a first portion extending generally parallel to the aircraft fuselage and a second portion having a continuously curving transition to the first portion and extending partially inboard from the first portion. The second portion of the track guides the door into and out of the opening in the fuselage, allowing the door to achieve a substantially flush condition when in its closed position.

Abstract: A kit for converting a standard swing-type gate into a rolling cantilever-type gate. The kit consists of commercially available roller assemblies and guide roller assemblies with associated attaching hardware and a unique top-rail extrusion.The top-rail extrusion is constructed in one piece with a flat ribbed side face having shoulders. Said shoulders either bolt directly to the gate in a horizontal orientation or attach to the gate horizontally with contoured brackets selected to fit the gate's structural members. One side of the top-rail extrusion is provided with a longitudinal compartment having a downward facing opening along its length. The compartment serves as a trackway for upper roller assemblies which are secured to support posts. Said upper roller assemblies access the compartment by way of the downward facing opening and support the gate.

Abstract: A latching and locking sliding door construction includes an elongated handle pivotally mounted to the door, the handle including a latch member located along one edge of the handle, the latch member adapted to cooperate with a catch member fixed to a portion of the entranceway. A key lock assembly is mounted in the door and adapted to lock the door in a closed position by preventing rotation of the handle and thereby disengagement of the latch member from the catch member. The lock assembly includes a manually actuable locking cam mounted on the other side of the door which permits the door to be locked and unlocked from inside the cabin independent of the rotational position of the key lock.

Abstract: An adjustable rolling type boxcar door has a main panel and a telescoping adjustable panel at its bottom for adjusting the overall height of the door to fit a variety of door openings. The adjustable panel is slidably retained between side frames in the main panel by stop blocks mounted along the inside edges of the side frames. The width of the door may be also adjusted by positioning a spark strip either closer or further away from the inside edge of the door opposite the closure mechanism. A pair of double roller, pivotally mounted bogeys are mounted in the adjustable panel and support the door from a door track mounted to the side of a boxcar. The double roller bogeys provide an improved traverse mechanism for supporting the considerable weight of a boxcar door and carrying it across what may be an uneven and rough track.
