Folding device as room divider or room closure

1. A folding device as a room divider or room closure, comprising:

at least one wing chain comprised of wings pivotably connected to one another such that the wings upon opening of the folding device are folded against one another;

wherein the wings have guide elements ( 10 ) forming a pivot axis ( 11 ), respectively, for the wings, wherein the guide elements ( 10 ) are connected to one side of the wings, respectively, or the wings are pivotably secured on a lateral frame;

a first guide rail ( 8 ) and a second guide rail ( 8 ) receiving the guide elements ( 10 ) such that the wings are slidably guided in the first and second guide rails ( 8 );

wherein at least one of the wings of the at least one wing chain is an opening wing ( 1 ) connected only to a single neighboring wing of the at least one wing chain and has a free wing edge ( 3 ) guided in the first and second guide rails ( 8 );

wherein at least the first guide rail has a stop ( 18 ) on one longitudinal side, wherein the wings cannot move past the stop ( 18 );

wherein the free wing edge ( 3 ) has a profiled strip ( 16 ) at a side facing the stop ( 18 ) and wherein the profiled strip ( 16 ) is immobile relative to the free wing edge ( 3 );

wherein the profiled strip ( 16 ) projects past the pivot axis ( 11 ) of the guide element ( 10 ) provided at the free wing edge ( 3 ) and has a slanted portion ( 17 ) facing the stop ( 18 ) and slanted in a direction toward the free wing edge ( 3 ), wherein the slanted portion extends at least across a height (A) of the stop ( 18 ).

2. The folding device according to claim 1 , wherein the slanted portion ( 17 ) is a rounded portion having a radius (R) originating at the pivot axis ( 14 ) of the guide element ( 10 ).

3. The folding device according to claim 1 , wherein at least one of the profiled strips ( 16 ) of two of the opening wings ( 1 ) meeting one another in a closed position of the folding device has a cover strip ( 19 ) extending across an opening height of the folding device between the raised stop ( 18 ) and the second guide rail ( 8 ) or between the raised stop ( 18 ) and an additional raised stop provided on the second guide rail ( 8 ), wherein the cover strip ( 19 ) covers at least partially the slanted portion ( 17 ) of the profiled strip ( 16 ).

4. The folding device according to claim 3 , wherein the cover strip ( 19 ) and the profiled strip ( 16 ) together form a monolithic part.

5. The folding device according to claim 3 , wherein the cover strip ( 19 ), when the folding device is closed, covers also the profiled strip ( 16 ) of the neighboring opening wing ( 1 ).

6. The folding device according to claim 5 , wherein the cover strip ( 19 ) and the profiled strip ( 16 ) of the neighboring opening wing ( 1 ) delimit a free space ( 20 ) allowing, when opening the folding device, a movement of the opening wing ( 1 ) away from a closed position in a direction toward the free wing edge ( 3 ).

7. The folding device according to claim 3 , wherein at least one of the profiled strip ( 16 ) and the cover strip ( 19 ) has a seal ( 26 ) for sealing relative to the neighboring opening wing ( 1 ) in the closed position or the lateral frame ( 22 ).

8. The folding device according to claim 1 , wherein the profiled strip ( 16 ) and the free wing edge ( 3 ) together are formed as a monolithic part.
