A door assembly is provided for which can alternate between a pivoting and a sliding configuration. The door assembly can include a door panel, a track, a first carriage assembly, a second carriage assembly, and a locking mechanism. The first and second carriage assembly can connect the door panel to the track. The first and second carriage assemblies can be slidably movable on the track, and the first carriage assembly can further include a pivot mechanism that pivotably couples the door to the track. The locking mechanism can configure the door between the sliding and pivoting configurations. For example, the locking mechanism can mechanically couple the door panel to the second carriage assembly in the sliding configuration and mechanically decouple the door from the second carriage assembly in the pivoting configuration.

A hinge for a bi-fold door is integrated with a pair of stiles. Each stile has a hinge flange integrated to the stile. Opposing stiles with opposing and aligned hinge flanges collectively create an integral hinge assembly that may be useful in thermal doors employing one or more thermal breaks.

A lifting system (11) for a liftable sliding leaf (10) comprises a lifting mechanism (16) which can be connected to a top part (12a) of the leaf (10), said lifting mechanism (16) being able to move between a first configuration and a second configuration where the leaf may slide or be locked, and a control member (12), which can be located on the fixed frame of the door and can be connected to the lifting mechanism (16) so as to switch it between the two configurations.

A slide and swing leaf/sash system includes a floor rail profile and a ceiling rail profile which are each C-shaped and in which at least two leaves/sashes arranged therebetween are displaceably guided, which leaves/sashes are mounted at least in each case by at least one carriage in the floor rail profile in such a way that, in the swiveled-in state of the leaves/sashes, the weight load of the leaves/sashes is completely absorbed by the floor rail profile. At least one lateral outlet opening for releasing a leaf/sash is arranged in the floor rail profile, a lifting runner, which is arranged above the floor rail profile, being mounted on at least one leaf/sash, a ramp element being arranged on the floor rail adjacent to at least one outlet opening and interacting with the lifting runner in such a way that the leaf/sash is raised on passing the ramp element.

A guide (10) for a liftable sliding leaf comprises at least two guide bars (14, 16), a first bar (14) of which can be connected movably to a support (24), fixed with respect to the leaf, and a second bar (16) can be connected integrally to a top part (12) of the leaf (11) so that both the bars (14, 16) are movable in a vertical plane.

The panel system includes lower and upper guides and at least one panel located between and connected to them, to move the panel on the lower guide. The panel system includes a hinge element fixed to the panel and allows the panel to be opened by turning essentially around a rotation axis. The panel system further includes at least two locking housings positioned successively on the upper guide. The locking housings include two opposite locking recesses, defining a circle with radius R3 and between which remains a passage with width P2. The hinge element can travel from one locking housing to another through the passage. The distance between the locking housings is distance P1, configured to be less than two times radius R3. The hinge element may include two locking cams and in addition a guiding edge remaining between them. The panel system locking arrangement includes the hinge element.

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.
