A door hanger system includes a housing and a bearing assembly that includes a cage and plural bearings within the cage. A slider is coupled with the bearing assembly and includes a bearing interface portion disposed within the bearing assembly and a door interface portion that is coupled with a door panel. The slider and the bearing assembly move in a first direction to move the door panel toward a closed position, or in a second direction to move the door panel toward an open position. A reset device is disposed within the bearing assembly and positioned between an end of the housing and the slider. The reset device interferes with the cage to move the cage toward the first end of the housing responsive to the slider moving in the second direction interfering with the reset device.

A roller carriage for the reception of a sliding door includes a roller module for the displaceable affixing at a roller running path and a basic body for the attachment to the sliding door. The roller module is configured of a first material and the basic body of a second material. The first material conducts structure-borne sound in a first sound conducting range and dampens the structure-borne sound in a second sound conducting range. The second material dampens structure-borne sound in the first sound conducting range and conducts structure-borne sound in the second sound conducting range.

A dual sliding door apparatus incudes a rectangular shaped frame configured for attachment to two opposing walls and a floor, the frame creating an opening, a top of the frame comprising a first rail parallel to a second rail, a first glass door sized so as to cover about one half of the opening, a pair of roller wheels coupled to a top of the first door, the pair of roller wheels including a concave outer surface designed to mate with the first rail, such that the first door rolls on the first rail, a second glass door with a pair of roller wheels coupled to a top of the second door, a first stop coupled to an outer circumference of the first glass door, and a second stop coupled to an outer circumference of the second glass door.

In a high-security sliding-door apparatus for closing and opening a corridor, the door having (a) a door frame having a track and a bi-directional effector, (b) a carriage having track-engaging rollers, (c) a slide plate slidably secured to the carriage and driven by the effector, and (d) a controller controlling slide-plate movement and enabling the door to be continuously closed but not locked, the improvement comprising centering apparatus for relative positioning of the slide plate and carriage, the centering apparatus including (1) a yoke attached to the slide plate at a yoke pivot and having a yoke cam surface thereabove, (2) a carriage-attached yoke-cam follower, and (3) springs having proximal ends attached to the yoke spaced above the yoke pivot and distal ends each attached to the carriage at points offset from the yoke pivot in opposite lateral directions, centering the door with the slide plate when unlocked.

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 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 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.

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.
