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.
Claims28
A closing body for closing and opening an access opening or a passage of a room,
- wherein a pressure difference exists between an interior and an exterior of the room,
- wherein the closing body (10) is formed as a pivotable door (11), pivotable window or pivotable closure,
- wherein a valve device (28) is provided on the closing body (10),
- wherein the valve device (28) effects a temporary pressure equalization when opening the closing body (10),
- wherein the valve device (28) is formed as a valve flap (32) and a release mechanism (42) is provided which opens the valve device (28),
- wherein a locking fitting (18) is provided for the closing body (10),
- wherein the release mechanism (42) is operatively coupled to the locking fitting (18) of the closing body (10),
- wherein the locking fitting (18) is a door lock (20) with an actuating pawl (22),
- wherein the locking fitting (18) includes a first latch (21) which holds the closing body in a closed state relative to a frame,
- wherein the closing body includes a second latch (38) which holds the valve flap (32) in a closed state relative to the closing body (10),
- wherein the door lock (20) is a panic lock (24) which can be opened from one side at any time in order to release an escape route,
- wherein the first latch (21) is a component of the panic lock (24),
- wherein the release mechanism (42) comprises at least one thrust body (39) which is operatively coupled to the locking fitting (18),
- wherein the at least one thrust body (39) is connected to a thrust rod (39′) which is moved correspondingly to a retraction movement of the first latch (21), and/or corresponding to a movement of the actuating pawl (22) or a pawl receptacle (42), and
- wherein the closing body (10) comprises an additional closing device (50) adapted to drive the valve flap (32) from an open position, in which an opening width is greater than zero and less than a residual opening threshold, to a closed position.
A closing fitting set for mounting on a door leaf (12) of a pivotable door (11) or a pivotable window or a pivotable closure, comprising:
- a locking fitting (18) for mounting on the door leaf (12),
- wherein the locking fitting (18) is a door lock (20) with an actuating pawl (22),
- wherein the locking fitting (18) includes a first latch (21) which holds the door leaf (12) in a closed state relative to a frame,
- wherein the door lock (20) is a panic lock (24) which can be opened from one side at any time in order to release an escape route,
- wherein the first latch (21) is a component of the panic lock (24);
- a thrust rod (39′) moved in correspondence with a retraction movement of the first latch (21) of the locking fitting (18) and/or moved in correspondence with a movement of the actuating pawl (22) or a pawl receptacle (42) of the locking fitting (18);
- an additional latch, which is formed as a panic latch lock (38) with a lock case (63) and a thrust body (39);
- a coupling mechanism (40) for connecting the thrust body (39) to the thrust rod (39′);
- and
- a valve device (28) which is designed as a valve flap (32) and can be inserted in an opening (30) of the door leaf (12);
- and
- an additional closing device (50) adapted to drive the valve flap (32) from an open position, in which an opening width is greater than zero and less than a residual opening threshold, to a closed position,
- wherein, within an intended assembly, a release mechanism (42) is formed by the connection of the thrust body (39) and thrust rod (39′), the release mechanism (42) being operatively coupled to the locking fitting (18) and configured to open the valve device (28), so that the valve device (28) effects a temporary pressure equalization when the door leaf is opened if there is a pressure difference over an interior and an exterior of the door leaf.
