Improvements to movable closure systems which aid installability and reliability of said systems can include wheels running along the top and bottom of individual slidable elements, the wheels oriented horizontally and disposed within a track configured for receiving the horizontal wheels. The horizontal wheels reduce the vertical profile of the track-engaging portions of the slidable elements, enabling more of the slidable element to be used for glass or other aesthetically-preferable transparent materials. A track leveling system enables installers to more easily deploy and properly tune the system between floors and casings which are not perfectly flush. A compression jamb permits closure of the system via slidable elements pressing into the jamb to deflect it in order to better seal the closure comprised of the individual slidable elements. A durable hinge mechanism permits the sliding elements to rotate in order to stack the sliding elements at one end of the system.

A door system includes a header having a guide rail that has a central portion having a notch. A panel hanger is slidably coupled to the header. A door panel has a handle end portion releasably coupled to the panel hanger and a pivot end portion pivotably coupled to the panel hanger. The panel hanger and the door panel slide in unison between a closed position and a fully open position along a longitudinal plane. An interlock plate is positioned to extend upwardly from the door panel, and has a downwardly extending guide slot that slidably receives the guide rail of the header. When the door panel is in the fully open position, the interlock plate is aligned with the notch of the guide rail of the header in a direction orthogonal to the longitudinal plane to facilitate a pivoting of the door panel away from the longitudinal plane.

The displacement device (10), which is provided for the installation in a door compartment (18) of a functional entity (1), comprises a drive device (2) preferably comprising a housing (210), a spring mechanism (211), a pull cord pulley (212) coupled to the spring mechanism (211), and a pull cord (22), which is wound onto the pull cord pulley (212) and is guided preferably via at least one deflection pulley (231, 232, 233) up to a holding element (33, 339; 72), a mounting profile (14), which is connected or connectable by mounting hinges (131) to a single-part or multi-part door (11), which is held vertically aligned and displaceable by a holding device (4); which is connected on an upper end piece to an upper guide carriage (5) that is supported displaceably on an upper guide rail (15) and/or which is connected on a lower end piece to a lower guide carriage (6) that is supported displaceably on a lower guide rail (16); and which, connected to the drive device (2), is automatically displaceable between a rear-sided end position (S2) at the rear-side of the displacement device (10) and a front-sided end position (S1) at the front-side of the displacement device (10); and

an adjustment device (3, X3), with which a pre-tension on the spring mechanism (211) of the drive device (2) can be set. According to the invention the adjustment device (3, 3X) is arranged separated from the drive device (2) and comprises an adjustment element (33, X33) which is rotatable and lockable or displaceable and lockable and which adjustment element (33, X33) cooperates with the pull cord (22) led out of the drive device (2) in such a way that the pull cord (22) is pullable out of the drive device (2) by rotation or displacement of the adjustment element (33, X33) to set a corresponding pre-tension of the spring mechanism (211).

A functional entity with door compartment and door with at least a first door element having rear and front-sided edges, connects to a displacement device inside the door compartment, displaces into the door compartment and pivots outside the door compartment covering an opening of the entity, wherein the displacement device includes a mounting profile connected by mounting hinges to the first door element rear-sided edge and held by a holding device, and wherein a first spacer device with a device body is at the door compartment entrance opening and includes a first spacer roller wherein the first door element rolls during displacement without device body contact of the spacer device. The first door element connects to a first door magnet member, and the spacer device connects to a first device magnet member, which interacts with the first door magnet member pulling the first door element against the spacer device.

A door system includes a header having a guide rail that has a central portion having a notch. A panel hanger is slidably coupled to the header. A door panel has a handle end portion releasably coupled to the panel hanger and a pivot end portion pivotably coupled to the panel hanger. The panel hanger and the door panel slide in unison between a closed position and a fully open position along a longitudinal plane. An interlock plate is positioned to extend upwardly from the door panel, and has a downwardly extending guide slot that slidably receives the guide rail of the header. When the door panel is in the fully open position, the interlock plate is aligned with the notch of the guide rail of the header in a direction orthogonal to the longitudinal plane to facilitate a pivoting of the door panel away from the longitudinal plane.

The present disclosure concerns a closure system comprising a closure hinged to a fame by a hinge device that permits transition of the closure between open and closed positions by a combined linear movement and rotational displacement.
