Abstract

A closing body allows closing and opening an access opening or a passage of a room in case of a pressure difference between an interior and exterior of the room. A closing fitting set and a door leaf are disclosed, by means of which closing fitting set and door leaf a closing body can be formed. The closing body is in the form of a pivotable door, a pivotable window or a pivotable flap. A valve device is provided on the closing body, which valve device effects a temporary pressure equalization during the opening or closing of the closing body. The valve device is in the form of a valve flap, and a release mechanism is provided, which opens the valve device. A locking fitting is provided for the closing body, and the release mechanism is coupled, for actuation, to the locking fitting of the closing body.

11. The closing body according to claim 1 ,

wherein the additional closing device is connected to a mechanical energy storage.

12. The closing body according to claim 11 ,

wherein the mechanical energy storage ( 52 ) is charged via a multiple movement of the actuating pawl.

13. The closing body according to claim 12 ,

wherein the mechanical energy storage ( 52 ) in a fully charged state supports a first actuation of the additional closing device and, without an intermediate charging process, at least one further actuation of the additional closing device.

14. The closing body according to claim 1 ,

wherein the additional closing device ( 50 ) comprises a bistable gear,

wherein the bistable gear is designed in such a way that the additional closing device ( 50 ) can be actuated

from a waiting position in which the additional closing device is out of engagement with the valve flap ( 32 ),

into a closed position with entrainment of the valve flap ( 32 ).

15. The closing body according to claim 14 ,

wherein the bistable gear is further designed in such a way that the additional closing device ( 50 ) after reaching the closed position is automatically moved back to the waiting position.

16. The closing body according to claim 1 ,

wherein the additional closing device ( 50 ) comprises a triggering means for triggering a movement of the additional closing device ( 50 ) from a waiting position to the closed position.

17. The closing body according to claim 16 ,

wherein the triggering means triggers the movement when the valve flap ( 32 ) is in a partially opened state in which an opening width is less than or equal to a residual opening threshold.

18. The closing body according to claim 17 ,

wherein the triggering means further triggers the movement only

when the partially opened state is reached at an end of an opening movement, and/or

when the partially opened state is present for a time greater than a waiting time threshold value.

19. The closing body according to claim 1 ,

wherein the closing body has a fold ( 56 ) which overlaps a frame ( 16 ) in a closed state.

20. The closing body according to claim 1 ,
