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 swivelled-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.

The invention relates to a windbreak system formed by a set of independent, folding panels that move longitudinally along an upper guide rail and another, lower guide rail and a non-movable folding door, in which each panel and the door include a rotating shaft and folding shaft. The panels are moved manually and do not have rollers, the entire weight of the panels resting on two strips of self-lubricating polymer inserted into slots in the lower rail.

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.
