The invention is an arrangement for moving fenestration panels, comprising fenestration panels (12a-12d) each having two guiding elements protruding respect to each of opposite guide sides, and two track constructions (5) having identical paths, each adapted oppositely arranged for guiding the two guiding elements.

In the arrangement the track constructions (5) are adapted to be arranged in a lower and upper structure portion, comprising first, second and third main track element (10a-10c) adapted to be arranged beside each other, and connector track elements (26a′-32b″) adapted for interconnecting the first and second main track element (10a, 10b), and the second and third main track element (10b, 10c), a track element-connecting pair (32a, 32b) of them is configured being suitable for separated transferring of the guiding elements of each fenestration panels (12a-12d) between the main track elements (10a-10c).

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.

A door assembly for a restroom stall having first and second opposed side walls and a front opening includes first and second housings defining first and second inner cavities and configured to be mounted on the first and second side walls, first and second doors moveably mounted on the first and second housings, each having opposed inner and outer surfaces that are curved and being moveable along an arcing path between an open position and a closed position. In the open position, the door is retracted within the respective housing and at least partially received in the respective inner cavity, and in the closed position, the door is extended outward of the respective housing relative to the open position. In the closed positions, the first and second doors combine to obstruct the front opening, and in the open positions, the first and second doors permit passage through the front opening.

An apparatus for window is used for moving a movable window plate among an insertion position for being inserted into an aperture portion of a fixed window plate, an extraction position for being extracted from the aperture portion toward an indoor side, and an opening position for being moved from the extraction position in a sliding direction that is different from an inserting and extracting direction to open the aperture portion. The apparatus includes a rotating shaft rotatably supported at a predetermined position for the movable window plate; a movement conversion mechanism configured to convert a rotation of the rotating shaft into a translation of the movable window plate between the insertion position and the extraction position; and a drive shaft, fixed to the rotating shaft, configured to rotate the rotating shaft around a central axis of the rotating shaft by revolving around the central axis of the rotating shaft.

Disclosed is a sliding door or window. The sliding door or window includes a door/window frame, a swing fastening mechanism is disposed at a lower end of a side of the door/window frame, and a locking structure is mounted on an upper end of the side of the door/window frame. The swing fastening mechanism and the locking structure are each provided with a snakelike groove inside which a shaft operative to slide along a groove orientation is arranged. A handle disposed on the door/window frame is operative to drive the shaft to slide in the snakelike groove, thereby forcing the swing fastening mechanism or/and the locking structure to swing.

The disclosure relates to a sliding fenestration system assembly, such as a door or window system. The sliding fenestration system includes a sill having a first track channel and a second track channel formed thereon. A sill track including a first track segment, a second track segment, and a third track segment is coupled to the sill such that the first track segment is positioned within the first track channel, the third track segment is positioned within the second track channel, and the second track segment extends between the first and second track channels. The system further includes a sliding panel having one or more bottom guide assemblies, the assemblies engaging the sill track and operable to accommodate movement of the sliding panel along the sill track to reduce friction at a sealing interface between the sliding panel and the fenestration frame assembly.

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.

A door-and-window system having a handle component (121), a transmission component (123) and a force receiving portion (12231). When the handle component (121) is operated, the force receiving portion (12231) moves along a first guide groove (12211) via the transmission component (123), and at the same time a driving portion (12232) moves along a second guide groove (12221). Due to a relationship between a guide member (1224) and a third guide groove (12212), a first base seat (1221) translates relative to a second base seat (1222) along a direction of the third guide groove (12212), such that a movable door-and-window (11) can abut tightly against or move away from a sealing member (24) on a door-and-window mounting profile (2).
