A sliding door system with a door includes a horizontally elongated member having a mounting portion with which it is mounted to a support structure, and a horizontally elongated track extending downwardly therefrom. The horizontally elongated track includes a horizontally elongated upper portion having a width, and a horizontally elongated protuberance below the upper portion having a width greater than the width of the upper portion. At least one sliding element is mounted to the top of the door and has a channel corresponding to the protuberance, and in which part of the elongated protuberance is disposed such that the sliding element is retained by and slidable on the protuberance. In some embodiments, a vertically extending rod is concealed between the front and back walls of the door and can be moved vertically in and out of an aperture in the protuberance to lock and unlock the door.

A magnetically levitating door is disclosed herein. The door may have a bracket having a magnet that is repelled from a magnet of a track. The magnet field of the bracket and the magnet field of the track may have different widths. The track may be disposed adjacent to a door opening. The bracket may have a guard in slidable engagement with the track to limit lateral movement of the magnet of the bracket disposed above and repelling the magnet of the track to levitate the door off of the track while preventing excessive lateral forces on the guard. The bracket may have at least one guide in slidable engagement with the track to secure the engagement of the bracket to the track and maintain vertical alignment of the bracket to the track.

A roller partition wall comprises a ceiling bracket, a floor bracket, a partition wall, and a plurality of rollers. A bottom surface of the ceiling bracket forms a first sliding slot, a top surface of the floor bracket forms a second sliding slot corresponding to the first sliding slot, a top surface and a bottom surface of the partition wall are respectively inserted into the first sliding slot and the second sliding slot, and the partition wall is capable of movably disposing between the first sliding slot and the second sliding slot. The rollers are disposed in the second sliding slot and are between the partition wall and the second sliding slot. Since the partition wall is disposed between the ceiling bracket and the floor bracket, the partition wall can be moved left and right between the ceiling bracket and the floor bracket during shaking in an earthquake.

A door mounting system for sliding translation of a door in one embodiment may include a longitudinally elongated support rail defining a mounting axis, a pair of wall mounts rigidly anchoring the support rail to a support surface, a door bracket slideably movable along the support rail, a door supported by the door bracket in a suspended manner, and a linear roller bearing disposed at an interface between the door bracket and support rail to facilitate movement of the door bracket along the support rail. The door is linearly translatable along the support rail in operation between open and closed positions. In one embodiment, an anti-sway clip disposed on the door bracket defines a stop surface configured to engage the support rail to arrest swaying motion of the door if a force is inadvertently applied to the door acting in a plane oriented transversely to the mounting axis.

An illustrative embodiment of a cargo vehicle is provided. A bulkhead is located on the cargo vehicle. The bulkhead includes an opening. A bulkhead door is located at the bulkhead. The bulkhead door is movable between open and closed positions with respect to the opening. A bulkhead door bearing slide assembly is located at a portion of the bulkhead door and is movable with the bulkhead door between the open and closed positions of the bulkhead door. At least one pin is attached to the bulkhead door bearing slide assembly and is disposed through at least one opening of at least a portion of the bulkhead door. The at least one pin is movable within the at least one opening of the at least the portion of the bulkhead door to movably couple to the bulkhead door.

A sliding screen door assembly includes a door panel having an outer frame and a screen portion. A sliding assembly slidably couples an upper portion of the outer frame of the door panel to a portion of a wall adjacent a doorway and the sliding assembly facilitates a horizontal sliding of the door panel relative the doorway between a closed position in which the door panel substantially covers the doorway and an open position in which the door panel is located substantially to a side of the doorway. A first barrier member is located above the sliding assembly and a second barrier member is located below the sliding assembly.

A building sliding door system separates a first building region from a second building region and has a frame structure that has a passage region and a wall shell region. A sliding door is displaced in the frame structure between a closed position and an open position, wherein the wall shell region at least partially receives the sliding door in the open position. An electromechanical drive unit and a control device control the displacement of the sliding door. A fire protection unit has a bracket and, movably mounted on the bracket, a fire protection device made of a material having a defined fire resistance. The fire protection device is horizontally displaceable within the wall shell region with respect to the bracket between a retracted position in which the sliding door is in the open position, and an extended position in which the sliding door is in the closed position.

A sliding door system with a door includes a horizontally elongated member having a mounting portion with which it is mounted to a support structure, and a horizontally elongated track extending downwardly therefrom. The horizontally elongated track includes a horizontally elongated upper portion having a width, and a horizontally elongated protuberance below the upper portion having a width greater than the width of the upper portion. At least one sliding element is mounted to the top of the door and has a channel corresponding to the protuberance, and in which part of the elongated protuberance is disposed such that the sliding element is retained by and slidable on the protuberance. In some embodiments, a vertically extending rod is concealed between the front and back walls of the door and can be moved vertically in and out of an aperture in the protuberance to lock and unlock the door.

A guiding device for an elevator door leaf that includes a body within which at least a first cavity open outwards of said body. The guiding device also includes a first spherical element rotatably inserted in the first cavity and arranged so as to protrude from the first cavity outwards and anti-friction means interposed between the first spherical element and at least one wall delimiting the first cavity to limit the movement of the first spherical element within the first cavity.

Automatic drive systems for movable partitions may comprise a floating jamb configured to attach to panels of a movable partition and glide within a pocket. A motor may be configured to extend the movable partition. The motor may be configured for mounting in the pocket on a back side of the floating jamb opposing a front side of the floating jamb to which the panels of the movable partition are configured to attach. An electronics enclosure may be sized and configured to contain electronics to connect to the motor. The electronics enclosure may be configured for positioning in the pocket on the backside in a location offset from the motor. A depth of the electronics enclosure, as measured in a direction in which the floating jamb is mounted to glide, may be less than or equal to a depth of the motor, as measured in the same direction.
