The invention relates to a sliding door fitting comprising a carriage, which is guided on a guide rail and which is connected to a housing of a retraction device in an articulated manner, wherein the retraction device has at least one, preferably two driver elements, which can be moved along guide tracks and which are spaced apart, the one or more driver elements being preloaded into a retraction position by means of at least one force accumulator, wherein the housing of the retraction device is preloaded in a direction rotation relative to the carriage.

A vehicle (e.g., a class-2 vehicle) with an improved cab door is disclosed. The vehicle can have a vertical plane that bisects the vehicle into a driver's side and an opposed side. The vehicle can comprise a chassis and a body supported by the chassis. The body can define a cab. The cab can define an opening configured to provide operator access to the cab. The cab door can be configured to travel about and between an open position and a closed position along a linear axis. In the closed position, the cab door can at least partially cover the opening of the cab. The linear axis can form an acute angle with the vertical plane that bisects the vehicle.

A vehicle sliding door assembly for selectively covering a bulkhead transit passage. The assembly includes a first door panel slidable between a first door closed position and a first door open position. A second door panel is slidable between a second door closed position and a second door open position. The first door panel includes a first door leading edge and a first door following edge. The second door panel includes a second door leading edge. The first door following edge engages the second door leading edge moving the doors in concert from the open position to the closed position. The first door leading edge engages the second door leading edge moving the doors in concert from the closed position to the open position.

A guide assembly for a sliding shower door is provided with a bracket sized to be fastened to a shower door opening. The bracket has a first lengthwise retainer. A guide with a second lengthwise retainer is sized to be retained by the first lengthwise retainer of the bracket. The guide has at least one channel formed therein and is sized to receive a shower door pane within the channel for translation of the shower door pane relative to the guide.

A sliding screen system for a sliding screen comprising a linear slide bar and at least one sliding member. The linear slide bar has a slide surface coated with a lacquer comprising a resin. The lacquer is in turn at least partly coated with a lipophilic composition coating. The lipophilic composition coating provides a slide layer on the slide bar with low friction. The sliding system is arranged to support a sliding screen, such as a sliding door or a sliding curtain, connected to the sliding member to allow for linear movement of the sliding screen along the longitudinal axis of the linear slide bar.

A retractable sliding door (10) with automatic alignment to the wall (12) during the closing phase, suitable to alternately open and close a through space (14) made along said wall, comprising a lower guide (18) fixed to the floor and an upper guide (20) forming a support beam. In the upper guide (20) paired prominences (50, 52) and (60) are made constituting the sliding tracks of two or more pairs of wheels (54) and single wheels (58) borne by a shaft (56) and combined with a frame (62) to form a carriage. The lower guide (18) interacts with a roller (24) suitable to fit into a shaped channel with a mixed-line extension (26) made along the lower head of the door (10); the upper guide (20) is provided with a shaped channel (78) having the same and parallel mixed-line configuration as said shaped channel (26). The upper head of the door (10) being provided with means for its suspension to the frame (62) constituting the carriage.

Systems and methods for providing a door seal system for top-hanging sliding doors. In some implementations, two angled mating surfaces are used, one angled surface on a fixed frame and one reversed angled surface on the slideable door panel. The slideable door panel slides directly parallel to the fixed door frame. A mating seal surface is created that is only in frictional contact for a small portion of the linear slide distance of the door panel. In some implementations, rather than placing two opposing angled seal surfaces, the sealing system has one angled surface on the fixed door frame. In such implementations, the sliding door panel is adjusted to be in a reverse angled orientation relative to the angled surface of the fixed door frame. Seal designs for the rear vertical edge of the slideable door panel are also provided herein.
