Abstract

A sliding-rotating leaf system especially for enclosing a balcony with glass has several leaves (1, 1′), which have an area element (2) and can be swiveled about an axis of rotation (4) and of which at least one additionally is constructed movably as a sliding-rotating leaf (1′). The sliding-rotating leaves (1′) are mounted movably in guide rails (7) at the rollers (5, 5′). Coupling elements (9) on the rail side, traversable by the sliding-rotating leaves (1′), are connected with the guide rail (7) and can be bought into engagement with at least one coupling piece (8) on the leaf side disposed at the axis of rotation (4) of the sliding-rotating leaf (1′) and lock the sliding-rotating leaf (1′) to prevent shifting when it is swiveled. The coupling piece (8), in a section at right angles to the axis of rotation (4), has the shape of a circle having a recess (14) at one side of the area element (2), as a result of which the extent of the coupling piece (8), from the axis of rotation (4) transversely to the area element (2) in the direction of the recess (14), is less than on the opposite side of the axis of rotation (4) and than on either side along the area element (2).

Dependent claims

A sliding rotating leaf system comprising:

a guide rail;
a plurality of area elements each having at least one roller movable on said guide rail, each of said area elements being movable on said guide rail between a folded position and an unfolded position;
a plurality of coupling elements arranged on said guide rail;
and
a coupling piece arranged on each of said area elements, a largest diametral dimension of a circular segment of each of said coupling pieces being equal to a distance between centers of adjacent one of said coupling elements whereby each of said coupling pieces serves as a stop for positioning said coupling piece of an adjacent one of said area elements in alignment with a respective one of said coupling elements;
said coupling piece of each of said area elements engaging a respective one of said coupling elements on said guide rail when said area element is in said folded position to prevent translatory movement of said coupling piece relative to said respective coupling element while permitting rotary movement of said coupling piece relative to said respective coupling element;
said coupling piece of each of said area elements rotating relative to said respective coupling element upon initiating movement of said area element from its folded position to thereby disengage said coupling piece from said respective coupling element to enable translatory movement of said area element toward said unfolded position as said at least one roller of said area element rolls on said guide rail.

A sliding rotating leaf system comprising:

a guide rail;
a plurality of area elements each having at least one roller movable on said guide rail;
at least some of said area elements being movable on said guide rail between folded and unfolded positions;
a plurality of coupling elements arranged on said guide rail;
a coupling piece arranged on at least some of said area elements, a largest diametral dimension of a circular segment of each of said coupling pieces being equal to a distance between centers of adjacent one of said coupling elements whereby each of said coupling pieces serves as a stop for positioning said coupling piece of an adjacent one of said area elements in alignment with a respective one of said coupling elements;
each of said coupling pieces engaging a respective one of said coupling elements on said guide rail when said area element is in said folded position to prevent translators movement of said coupling piece relative to said respective coupling clement while permitting rotary movement of said coupling piece relative to said respective coupling element;
said coupling piece of each of said area elements rotating relative to said respective coupling element upon initiating movement of said area element from its folded position to thereby disengage said coupling piece from said respective coupling element to enable translatory movement of said area element toward said unfolded position as said at least one roller rolls on said guide rail.
