Definitions
- the present disclosure relates to a closing body, in particular a door, a window or a flap, for closing and opening access openings or. Passageways of a room, where there is a pressure difference between the inside and the outside of the room.
- a valve device is provided on the closing body, which a temporary pressure equalization when opening or. causes when closing the closing body.
- the disclosure particularly relates to a fire door.
- the space is in particular an escape route space of a civil building, further in particular a stairwell.
- the disclosure also relates to a set of locking fittings and a door leaf, which can be used individually or together to form the locking body.
- closures known in practice are not optimally usable in a situation in which there is a pressure difference between the interior and the exterior of the room, which is caused by the closure are separated from each other . This is reflected in particularly negative consequences in the event of a fire.
- Escape routes in buildings can include several rooms separated from one another by locks and must ensure a safe escape for at least 90 minutes in the event of a fire.
- smoke pressure systems pressurize escape route spaces, particularly stairwells in buildings.
- the smoke pressure systems are switched on automatically by smoke sensors.
- the smoke pressure systems constantly force fresh air into the escape route room and generate overpressure in it compared to adjacent rooms (usable areas). In this way, the penetration of (further) smoke from the adjacent room into the escape route room or the stairwell prevents .
- smoke that has already accumulated in the escape route area is preferably displaced upwards.
- a door opening force of 100N is already so high that younger people cannot unequivocally muster it.
- an air speed of 2m/s in the door cross-section must be ensured when a door of the escape room is opened.
- the door opening force that a person has to use to open the door is made up of the force of the overhead door closer and the force resulting from the pressure on the door leaf (pressure difference force).
- pressure difference force With conventional doors with approx. 2sqm area, the pressure in the escape route is therefore limited to 30-40 Pa (Pascal). However, this pressure is often not sufficient to achieve the required 2 m/s in the door cross-section. In practice, therefore, significantly higher pressures occur in the escape route. Also due to thermal effects, the pressure in the escape route can be at least locally far above the intended 30-40 Pa, which leads to correspondingly higher pressure difference forces on the doors.
- the doors of the usable areas on the upper floors usually open towards the stairwell. If, for example, a door is opened between a usable area on an upper floor and the stairwell, the door must be opened against the overpressure in the stairwell, whereby the door opening force can be far above the intended limit of 100 Newton and up to the pressures that actually occur in practice can correspond to 2000 Newtons. Such a door opening force can often not be applied by a single person.
- DE 27 39 034 A1 discloses a door locking system in which a door is held in the position in which it was last opened until a control signal is received either from a detector arrangement or a power interrupt switch.
- the door can also be closed manually by a person pushing against the door with sufficient force to initially overcome the restraining force of a door closer. After the force is overcome and the door begins to close, the door closer will close the door the rest of the way.
- DE 19937 532 A1 describes an arrangement for setting a pressure difference between an escape route in a building and its surroundings.
- the arrangement includes an outflow opening, which connects the rescue route with the environment and whose flow resistance can be varied by means of a preferably electrical adjustment device.
- a pressure sensor is provided in the rescue route, which measures the pressure at least in the rescue route at one point in time.
- a control unit is provided in the arrangement, which has an input for the signal from the pressure sensor and an output for the actuating device.
- the pressure sensor is connected to the input of the control unit via a signal line and the adjusting device is connected to the output of the control unit via a control line.
- the control unit is set up in such a way that it generates an actuating signal for the actuating device when the measured pressure difference reaches and/or exceeds a defined, preferably preset, threshold pressure difference.
- EP 1 835 969 B1 discloses a mobile smoke and fire protection device in buildings for installation in the event of a fire, with a sealing unit that can be attached in or on an opening in a wall, ceiling or floor.
- the shape and size of the sealing unit is adapted to the opening and is at least partially provided with a flexible material.
- the through-opening is intended for people and/or with a through-opening for equipment, fire-fighting equipment and the like.
- the passage opening and/or the feed-through opening can be covered at least partially.
- the Sealing unit is provided with a tensioning or clamping frame.
- DE 1 148 468 B discloses a combined drive device for two pivotable door leaves which are moved by a motor and are arranged at the ends of an antechamber for a space in a nuclear reactor which can be closed off in a gas-tight manner.
- Each of the door leaves includes a pressure equalization valve, which is designed as a cone plug.
- the doors can only be moved in a way that is coordinated with one another, so that at all times at least one of the doors is closed in a gas-tight manner. Closing of one door, closing of the valve there and subsequently opening of the other door are triggered via a push button arranged separately in the room. Before the other door is opened, the valve there is also opened, as a result of which permanent pressure equalization is brought about.
- EP 2 337 912 B1 describes a high-rise building with a stairwell, an air supply shaft, inflow openings which connect the air supply shaft to the stairwell and a pressure system for keeping the stairwell free of smoke. Tables show how much the actual pressures in the stairwell can vary due to the shaft effect.
- the stairwell is replaced by at least one bulkhead divided vertically into several subspaces. Each bulkhead has a door that allows passage from one compartment of the stairwell to the adjacent compartment.
- a more homogeneous pressure maintenance in case of fire and thus a limitation of the door opening force to standard values.
- the task of the innovation is therefore to avoid the disadvantages of the prior art and to create a closing body such as a door, a window or a flap, which can also be used with pressure differences across the closed closing body or. at a pressure difference between the exterior and the interior of the escape route space can be opened as evenly as possible. It is also an object of the innovation to show an associated set of locking fittings and an associated door leaf.
- the object is achieved in that s in a closing body for closing and opening of access openings or. Passages of a space of the type mentioned at the outset are provided with a valve device which causes a temporary pressure equalization when the closing body is opened.
- the valve device is preferably designed to be passive with regard to the opening movement. This means that the opening movement takes place without the support of a drive or a biasing means.
- the valve device causes a temporary pressure equalization depending on the requirement.
- the release mechanism releases an opening of the valve device. Whether the opening actually takes place can depend on the external conditions, in particular whether there is actually a sufficiently high pressure difference. Unnecessary openings of the valve device are thus avoided when there is no need for this.
- the opening movement of the valve device is preferably effected by a pressure difference force which results from the pressure difference between the interior and the exterior results .
- the opening movement can in particular be brought about exclusively by the pressure difference force.
- the valve device can further preferably be designed to be active with regard to the closing movement.
- This means that the closing movement can be supported by a drive.
- the at least one drive can be a flap closer.
- the closing body can have an additional closing device.
- the valve device is preferably self-closing. This means that the closing of the valve device is initiated when and in particular as soon as a pressure difference force has dropped to a certain level, in particular to a level that is smaller than the forces of the at least one drive acting in the closing direction.
- the innovation is based on the principle that the temporary pressure equalization by means of the valve device no longer leads to an excessive increase in the door opening force or to a powerful impact of the closing body due to the pressure. Rather, a pressure difference force is temporarily reduced by the valve device and the enabled pressure equalization in order to enable an unhindered escape.
- valve device is replaced by the innovation after the escape has taken place closed again so that the pressure difference can build up again.
- the closing body When actuated, the closing body opens a valve device arranged in the door leaf, so that a pressure equalization takes place virtually at the same time as the door is opened or with a minimal lead time. This eliminates the force resulting from the pressure and the closing body can be opened largely independently of the pressure difference. This allows a smoke pressure system z. B. can be operated at higher pressure, which improves fire safety without presenting an obstacle to people escaping. With higher pressure, the speed of 2m/s is then regularly reached in the door cross-section, so that fire safety is improved.
- Such a closing body can be used both with positive pressure and with negative pressure.
- Doors, windows or flaps regularly form the bodies with which openings in escape routes are closed.
- an advantageous embodiment of the closing body according to the invention is that the closing body is designed as a pivoting door, pivoting window or pivoting flap.
- a further advantageous embodiment of the closing body according to the invention is that a locking fitting, in particular a mechanical, electronic, pneumatic and/or hydraulic one Lock fitting is provided for the closing body.
- the locking of closing bodies can be realized in a suitable manner with such fittings.
- such locking fittings also allow the locking mechanism to be controlled externally.
- a control unit that z. B. is designed to be processor-controlled, such a locking fitting can be controlled, for example in order to release or execute or prevent an opening movement or closing movement.
- the required force can be used with such systems to lock the closing body.
- the valve device can also be designed accordingly in order to activate it in a suitable manner.
- a release mechanism in particular a mechanical, electronic, pneumatic and/or hydraulic release mechanism, which opens the valve device and optionally also closes it, is therefore preferably provided in one embodiment of the closing body according to the invention.
- the release mechanism can be designed in particular to open or close the valve device as required, i. H . in particular only when there is a sufficiently high pressure difference.
- the release mechanism can be designed to only open the valve device when the pressure difference exceeds a threshold value.
- the release mechanism is coupled to the locking fitting of the closing body in an actuation-effective manner.
- the actuating coupling means that an actuation of the locking fitting, ie for example the manual movement of an actuating pawl or the controlled activation of an actuator of the locking fitting, is converted via the release mechanism into a coupled opening of the valve device.
- the actuation-effective coupling automatically causes the valve device to open when the locking fitting is actuated. So it requires no separate additional actuation to open the valve device. A person attempting to escape in an emergency therefore does not need to actuate a separate opening means in order to reduce the pressure difference across the closing body. Rather, this happens automatically as a result of the actuation-effective coupling with the locking fitting.
- the closure body comprises at least two latches, a first latch which holds the closure body in the closed state relative to a frame, and a second latch which holds the valve device in a closed state relative to the closure body.
- the release mechanism and in particular the preferably Mechanics used opens, for example, these two door latches, one to open the door and a second to release the valve device, such as the flap.
- the flap preferably only opens in the event of overpressure.
- the flap preferably also closes automatically if the pressure drops.
- the regulations for fire and smoke protection can be satisfied here.
- a further advantageous embodiment of the closing body according to the invention is that a pressure sensor is provided which controls the release mechanism.
- the release mechanism reacts to the control signals generated by a pressure sensor.
- the valve device can then be controlled when the pressure z. B. in the pressurized space becomes too high and exceeds a predetermined threshold.
- Release mechanism has a means, in particular a control means, which opens the valve device in time before the closing body.
- the control means can be designed in any way. It can be formed, for example, by a gear mechanism which causes a second latch, which secures the valve device, to open earlier than a first latch, which secures the closing device, when the actuating pawl moves. Such a gear between a sliding body, through which the second case is moved, and a locking fitting be connected to the closing body.
- the means can be formed in that the first latch and the second latch are designed with different (effective) tongue lengths, so that the second latch falls below the release threshold earlier than the first latch when the movement speeds are essentially the same.
- the means which first carries out the pressure equalization before the closing body can be opened. This can e.g. B. be done by a delayed release of the locking fitting.
- the valve device for pressure equalization is first actuated before the closing body can be opened.

- Figure 12 A lock fitting set and a door leaf.
- reference numeral (10) designates a closing body.
- the closing body (10) is formed by a door (11).
- the example of the door (11) represents the most frequently expected embodiment in practice and is also representative of the other possible embodiments of the closing body (10), in particular a window or flap.
- the invention is explained below using the example of the door (11).
- the person skilled in the art knows that the components provided for a door, such as locking fittings, door locks, hinges, door frames, etc., can be present in windows and flaps as well as other pivoting closing bodies in a corresponding manner, i.e. for example as window locks, hinges and window frames or as flap locks , hinge and flap frame.
- no conceptual differentiation is made between door leaf versus window sash or flap sash, and door lock versus window lock or flap lock.
- the terms used for the example of the door (11) also stand for functionally equivalent components of a window and a flap.
- the door (11) comprises a door leaf (12) which is pivotably attached to a door frame (16) via hinges (14).
- door leaf thus means any movable main part of the closure body (10) that opens or closes the access opening to the space that is pressurized.
- the door leaf (12) can close the door frame (16) in a form-fitting manner, so that no air or no smoke (8) can pass through this door (11) when it is closed.
- the door frame (16) is anchored in a passage of masonry, not shown here.
- a locking fitting (18) contains in the example of Figure 1 a door lock (20) with an actuating pawl (22).
- the actuating pawl (22) can have any physical form. In the form shown, it can be designed as a rotatable handle (door handle, window handle, etc.). Alternatively or additionally, it can be designed as a panic bar, as a push bar or as a rotary knob.
- the actuating pawl (22) can comprise an actuator or be connected to an actuator, the actuator being activated by a control means.
- the control means can be of any type, for example a door opening switch placed on or near the door, or a building controller.
- the door lock (20) is preferably a panic lock (24) which can be opened at any time from one side, mostly from the inside of a usable area (3) of a building (1).
- the panic lock (24) can be locked from the other side, although this is optional.
- the fact that it can be opened from one side ensures that the access opening or passage to the escape route space can be released at any time from one side by actuating the locking body, even if the panic lock (24) is released from the other side could not be opened. This ensures an escape route through the door (11) to the outside at all times.
- the door (11) is closed automatically by a spring-loaded door closer (26).
- the door closer (26) is preferably attached to the closing body (10) or integrated into the closing body (10).
- the door closer (26) can be attached to the door frame (16).
- the door closer (26) can be integrated into a hinge (14) of the closing body (10).
- the term "resilient” includes any energy storage technology approved for door closure (e.g. window or flap closure) on escape routes, e.g. mechanical springs, gas springs or systems for storing potential energy.
- a mechanical valve device (28) is located in the lower area of the door leaf (12).
- an opening (30) is provided in the door leaf (12), which is opened or closed with the valve device (28).
- the valve device (28) comprises a valve flap (32) which is pivotably arranged on the door leaf (12) with hinge straps (34).
- the hinge straps (34) are on the outside of the door leaf (11) and the valve flap (32) arranged.
- the hinge straps (34) can be integrated into the valve flap (32) or into the opening gap between the valve flap (32) and the opening (30), which is shown by way of example in FIGS. 11A and 11B.
- a spring-loaded flap closer (36) preferably automatically closes the opening (30) with the valve flap (32) again.
- the flap closer (36) can have the same or a different design than the door closer (26). It can preferably be integrated into the valve flap (32) or the opening gap between the valve flap (32) and the opening (30) in the door leaf (11).
- the flap closer (36) can be integrated into the closing body (10) (cf. FIGS. 5A to 6C). Again alternatively, the flap closer (36) can be integrated into a hinge (34) with which the valve flap (32) is pivotably mounted on the closing body (10).
- a second latch preferably designed in the form of a panic latch lock (38), secures the valve flap (32).
- the fuse preferably acts in one direction, so that the valve flap (32) only opens to one side.
- the opening direction (V) of the valve flap (32) is shown in different versions in the figures, in particular in Figures 3 to 7.
- a panic latch lock (38) preferably includes a lock case (63) on or in which the second latch and any movement gearing (not shown) are accommodated.
- the lock case can be inserted into a corresponding case receptacle (54, 55).
- the door lock (20), in particular the panic lock (24), can also include a lock case (19) and can be inserted into a case receptacle in the door leaf (54, 55).
- the door lock (2) in particular the panic lock (24), and the panic latch lock (38) are preferably mechanically coupled to one another via a coupling mechanism (40). They can be opened simultaneously or with a slight delay in relation to one another by means of a release mechanism (42).
- the valve flap (32) preferably opens first in order to establish pressure equalization.
- the actuation-effective coupling can be designed not mechanically but, for example, electrically, hydraulically or pneumatically.
- the release mechanism (42) can also receive a signal from a pressure sensor (43), which controls the release mechanism (42) in a suitable manner for opening and closing.
- An opening limiter (44) preferably only allows a defined opening range of the valve flap (32). In this way it can be prevented that the valve flap (32) opens too far and, for example, injures a person standing in front of the door or others damage.
- the opening limiter (44) can dampen the opening movement of the valve flap (32). The damping can possibly be provided exclusively in the opening direction, but not in the closing direction of the valve flap (32).
- Opening limiter (44) can have any configuration. According to the example in FIGS. 1 and 5A to 6C, it can be in the form of a mechanical stop and can be arranged, for example, in the gap between valve flap (32) and opening (30). Alternatively or additionally, the opening limiter (44) can be integrated into another element, for example into the flap closer (36) or a hinge (34).
- a locking mechanism (46) allows the valve flap (32) to snap in so that it does not move unintentionally.
- the locking mechanism can be of any design.
- the locking mechanism (46) can be part of the release mechanism (42) and in particular cause or contribute to the valve device (28) opening or closing depending on the requirement, i.e. in particular only when there is a sufficiently high pressure difference.
- FIGS 8A and 8B show a detail of a sectional view of the valve flap (32) and the closing body (10) with an exemplary embodiment of a locking mechanism (46).
- the detent mechanism includes a spring-loaded element, such as a rounded pin, which is drained in the direction of a counter-body, such as a detent. Alternatively, any other designs can be provided.
- the detent mechanism is arranged in such a way that it generates a limited counterforce which counteracts the opening movement of the valve flap (32) and any closing movement. This opposing force is called the cogging force (G'). It is preferably adjustable or controllable.
- the latching force (G') is preferably selected in such a way that it only allows the valve flap (32) to open when the pressure difference across the closing body (10) exceeds a specific threshold value. It can thus be prevented that the valve flap (32) is accidentally opened, for example on the basis of inertial forces when the closing body (10) is actuated with a force.
- a retractable sealing rail (48) seals the door (11) so that no smoke (8) can penetrate through the slot between the floor and the door leaf (12).
- the closing body (10) and the valve device (28) can have various other seals (58).
- the closing body (10) preferably has a fold (56), in particular a door fold, which overlaps the frame (16) in the closed state.
- the valve flap (32) preferably has a fold (57), in particular a flap fold, which overlaps the inner contour of the opening (30) in the closed state.
- a seal (58) is preferably arranged in a fold (56, 57) (cf. Figures 1, 8 and 11.
- FIG. 2 shows an example of a building (1).
- the building (1) has several rooms (2) whose access openings or passages can be opened or closed by means of a closing body (10) according to the present disclosure.
- a closing body (10) according to the present disclosure.
- the building has a smoke pressure system (5) .
- This is designed to continuously pump fresh air into the stairwell (2, 2a), so that an overpressure (P+) is created there.
- P+ overpressure
- the pressure level in the stairwell (2a) should still be higher than the external atmospheric pressure (Pa).
- the lock (2b) could also be pressurized.
- the building (1) according to FIG. 2 comprises a controllable smoke and heat exhaust (6) in the upper area of the stairwell (2a).
- This can be a controllable flap whose opening cross-section can be regulated in such a way that the smoke (8) introduced can escape there, but on the other hand the overpressure (P+) in the stairwell (2a) is maintained at a certain level.
- all closing bodies (10) that are attached to access openings or passages to the pressurized space (2) are usually closed. This is done in particular by the door closers (26), which can be actuated in an additionally controlled manner for this purpose.
- the locking fittings (18) of the closing body (10) can be designed to be controllable, for example in order to retract the bolt (23) of the door locks (20) - if such are present.
- the first traps (21) of the door locks (20) usually remain in the extended position, but are possibly switched softly so that the closing bodies (10) can be opened and closed again.
- the closing bodies (10) which close access openings or passages to the pressurizable space (2), include all the doors shown on the upper floors, which are connected to the stairwell (2a) and the lock (2b ) and the ground floor door leading to the foyer (4). Furthermore, one or more windows or flaps can be present, which are designed as a closing body (10) according to the present disclosure. In the example of Figure 2, a window is shown as a representative, which can release an exit to the roof above the foyer (4).
- the closing bodies (10) are usually installed in such a way that they open in the assumed direction of escape. This means that the door opening direction (R) is usually identical to the escape direction.
- door opening direction analogously includes the opening direction of a window or flap.
- the opening direction (V) of a valve flap (32) can be provided in the same direction or in the opposite direction to the door opening direction (R), which can lead to different functions and advantages based on the following examples.
- Figure 3 explains an example that can occur at the door of the lowest usable area (3). It is assumed that a person is in the usable area (3) and would like to flee to the stairwell (2a) through the passage which is closed by the closing body (10), here a door (11). In this case opens the door in the opening direction (R) towards the stairwell (2a) where the overpressure (P+) prevails. The significantly lower normal pressure (P-) prevails in the usable area (3).
- P- normal pressure
- This pressure difference force (F) can, for example, have the level of approximately 100 Newtons provided according to the standard. However, it can also be significantly higher and amount to 1000 Newtons, 2000 Newtons or even more.
- the fleeing person usually does not know anything about the pressure difference force because this force is not visible.
- FIG. 5A shows how the second latch or the panic latch lock (38) opens as a result of the movement of the actuating pawl (22) and the actuating coupling. This releases the valve flap (32).
- the opening direction (V) of the valve flap (32) is in the opposite direction to the door opening direction (R) .
- the pressure differential force (F) thus acts in the valve flap opening direction (V) and will continue to be present until the valve cap (32) is released.
- the pressure differential force (F) pushes the valve flap (32) open with great force from the moment of release in the direction of the lower pressure level, in this case the normal pressure (P-).
- the valve flap (32) opens very quickly. If there is a latching mechanism (46) on the valve flap (32) (not shown in FIG.
- the latching force (G') of the latching mechanism (46) is overcome. If a flap closer (36) is provided on the valve flap (32), the valve flap (32) is opened against the closing force (S) of the flap closer (36), the flap closer being elastically tensioned.
- An opening limiter (44) is preferably provided, which allows a certain opening width of the valve flap (32) up to a threshold value, but not beyond it.
- the threshold value can be in the range of a few centimeters and in particular less than 10 cm, more particularly less than 7 cm.
- FIG. 5B explains the state that arises as a result of the opening of the valve flap (32). At least in a local area on both sides in front of and behind the closing body (32), there is a pressure equalization, represented by the symbol (P-) for the normal pressure both sides of the closing body (10) in front of and behind the opening zone of the valve device (24).
- P- a pressure equalization
- the fleeing person can open the closing body (10) unhindered. Since the pressure difference force (F) is no longer effective or hardly effective, the flap closer (36) can move the valve flap (32) back into the closed position. The valve flap is secured in the closed position by the second latch or the panic latch lock (38). After the fleeing person has left, the door closer also brings the closing body (10) back into the closed position in order to separate the pressurized room (2), here the stairwell (2a), from the usable area (3) as gas-tight as possible .
- Figure 4 illustrates another case, which can be found, for example, on the door on the ground floor of the house according to Figure 2 can occur.
- the pressure difference across the closing body (10) is in the opposite direction to the situation according to FIG.
- FIG. 6A shows how the second latch or the panic latch lock (38) opens again as a result of the movement of the actuating pawl (22) and the actuating coupling, specifically in this case earlier than the first latch (21).
- the valve flap (32) is (initially exclusively) released.
- the opening direction (V) of the valve flap (32) is now in the same direction as the door opening direction (R), ie the situation is the opposite of that in FIG. 5A.
- the pressure differential force (F) acts again in the valve flap opening direction (V) and will also continue to be present until the valve cap (32) is released.
- the pressure difference force (F) will push the valve flap (32) open with great force from the moment of release in the direction of the lower pressure level, in this case the normal pressure (P-).
- a very rapid opening movement of the valve flap (32) also occurs here.
- a locking mechanism (46) on the valve flap (32) for example a spring-loaded locking lug, the locking force (G′) of the locking mechanism (46) is overcome.
- a flap closer (36) is provided on the valve flap (32), the valve flap (32) is opposed to the Closing force (S) of the flap closer (36) opens, the flap closer being stretched elastically.
- An opening limiter (44) is preferably provided, which allows a certain opening width of the valve flap (32) up to a threshold value, but not beyond it.
- the threshold can be in the range of a few centimeters.
- FIG. 6B explains the state that arises as a result of the opening of the valve flap (32).
- the magnitude of the pressure difference drops massively in this example as well, so that the pressure difference force (F) is almost eliminated. This effect occurs again within a fraction of a second.
- the first latch (21) now opens with a slight time delay, so that the closing body (10) is unlocked overall and can be opened normally.
- the intruding person does not notice that the door had previously been subjected to a force of, for example, 1000 Newtons or more in the opening direction just fractions of a second previously.
- the flap closer (36) can also move the valve flap (32) back into the closed position in this example.
- the valve flap (32) is secured in the closed position by the second latch or the panic latch lock (38).
- the door closer (26) brings the closing body (10) back into the closed position in order to move the pressurized room (2), here the stairwell (2a), away from the usable area (3) as gas-tight as possible to separate.
- first valve flap (32) in a first vertical section of the closing body (10) and a second valve flap (32) in a second vertical section.
- the first valve flap (32) can be provided in the upper or lower half of the closing body and the second valve flap (32) in the other half.
- valve flap (32) By limiting the opening width of the valve flap (32), the risk of injury is significantly reduced.
- the altitude of the arrangement of a valve flap (32) can bring about additional advantages and a further reduction in the risk of collision.
- a valve flap whose opening direction (V) is in the same direction as the door opening direction (R) can advantageously be arranged in an upper section of the closing body (10), which is to be expected in particular at chest height of the fleeing person. This is because a person who wants to open a door by pulling is generally further away from the door leaf with the upper part of the body than with the lower part of the body (cf. pose in FIG. 4). An arrangement in The upper section thus promises a lower risk of collision.
- a valve flap whose opening direction (V) is in the opposite direction to the door opening direction (R) can advantageously be arranged in a lower section of the closing body (10), which is to be expected in particular at leg or knee height of the fleeing person. Because a person who wants to open a door by pressing is usually farther away from the door leaf with the lower body section than with the upper body section (cf. Pose in FIG. 3).
- the door (11) can only be opened outwards—seen away from the pressurized room—so that the escape route can be released quickly.
- a person entering the pressurized room from the outside and opening the door (11) would slam the door (11) open due to the pressure and possibly even injure the person.
- the valve flap (32) of the valve device (28) therefore first opens in order to equalize the pressure. Only then can the door (11) be opened essentially without pressure.
- the valve flap (32) is mechanically connected to the panic lock (24) via the coupling mechanism (40).
- the release mechanism (42) releases the valve device (28) and then the door (11).
- Figure 9 illustrates in a diagram the curves of a pressure difference force (F) in the opening direction of the Valve flap (32) acts, and the opposite closing forces (G, G', S) for the example of Figures 4 and 6A to 6C over time.
- the opening and closing states of the closing body (10) and the valve flap (32) are illustrated below the diagram.
- the closing body and valve flap (32) are closed.
- the full pressure difference force (F) is present across the valve flap (32).
- the valve flap (32) is held in the closed position by the second latch (38).
- the second trap (38) applies a reaction force as the closing force (G) which has the same amount as the pressure difference force (F).
- Part of the closing force (G) may also be generated by permanent pretensioning of the flap closer (26).
- the distance between the times t1 and t2 is shown in FIG. 9 in a significantly enlarged manner in order to allow the diagram to be read. In fact, these points in time can be only a few fractions of a second apart.
- the pressure difference force (F) acts on the valve flap (32) to an ever smaller extent, approximately with the cosine component of the door opening angle.
- valve flap (32) begins to close. This moment is marked in Figure 9 as an example with the term "F ⁇ G".
- the closing force can be applied to a large extent by the force (S) of the flap closer (26).
- the closing force (S) of the flap closer (26) is so high that it overcomes those forces that may be generated by the detent mechanism (46) and/or the insertion of the (soft-switched) second latch (38) (cf. FIG. 8b).
- States Z4 and Z5 illustrate the closing movement of the closing body (10), which is caused by the door closer (26).
- the closing body (10) is overall again in the closed position.
- the various seals (48, 58) preferably provide a substantial volumetric separation between the interior and the exterior. A dynamic pressure can build up again as a result of the air supplied by the smoke pressure system (5). The temporary pressure equalization is thus ended.
- FIG. 10 shows an alternative course of force analogous to FIG. 9.
- the opening of the closing body (10) is initiated, but only partially.
- Such a condition could occur, for example, if a person noticed while the actuating pawl (22) was still moving that there was a dangerous situation behind the closing body (10) and then refrained from opening the closing body (10) further while the valve flap ( 32) has already been released and pressure equalization initiated.
- the processes for the times tO and tl are identical to the example in Figure 9.
- the sealing closure of the valve flap (32) could be jeopardized, so that the protection against the passage of smoke at the access opening or the passage would be impaired or the achievement of the desired overpressure level in the escape room again be impaired could. If such a fault would only occur on one or a few closing bodies (10) of the building (1), the smoke pressure system (5) would probably be sufficient to achieve the desired effect despite a leakage flow occurring. Nevertheless, it would be advantageous to avoid such states with an undesired residual opening of the valve flap.
- FIGS. 11A and 11B explain an advantageous embodiment of the closing body, with which an undesired remaining opening of the valve flap (32) can be eliminated.
- the closing body (10) preferably has an additional closing device (52) which is designed to move the valve flap (32) from an open position in which the opening width is greater than zero and less than one Remaining opening threshold is powered to move to the closed position.
- the auxiliary locking device can be of any suitable construction. For example, it can act mechanically and be designed as a movable and drivable lever, which is assumed to be representative in the following.
- the additional closing device (50) can act in any other way, in particular magnetically, electrically, hydraulically or pneumatically.
- the additional closing device (50) preferably has a movement device, the movement device being designed in such a way that the additional closing device (50) can be actuated from a waiting position ( Figure 11A), in which the additional closing device can be operated without engaging the valve flap (32 ) stands, is moved with entrainment of the valve flap (32) into a closed position (11B).
- the movement device can have any desired design. In the example of FIG. 11, it can be a bistable gear.
- the movement device can also be designed in such a way that the additional closing device (50) is automatically moved back to the waiting position after the closed position has been reached. In this way it is achieved that the additional closing device does not impede an opening movement of the valve flap (32), ie none causes additional force (G) in the closing direction. In other words, the additional closing device ( 50 ) acts exclusively in a driven manner in the closing direction of the valve flap ( 32 ).
- the additional locking device ( 50 ) has a triggering means in order to trigger a movement of the additional locking device ( 50 ) from the waiting position into the locking position.
- the triggering means can have any configuration. In the example of FIG. 11, the triggering means is not shown. However, it could be designed, for example, as a mechanical switching means, in particular as a driver on one side, which is activated when the valve flap (32) moves in the closing direction when the remaining opening threshold value is reached.
- the triggering means is thus preferably designed in such a way that it triggers the movement when the valve flap ( 32 ) is in a partially open state in which the opening width is less than or equal to the remaining opening threshold value.
- a particularly energy-efficient effect is achieved if the triggering means is designed such that it continues to trigger the movement only when the partially open state is reached at the end of an opening movement and/or when the partially open state is present for a period of time which is greater than a waiting time threshold.
- This means that the additional closing means (50) is only activated if the normally provided closure according to the example in FIG. 9 based on the force (S) of the flap closer is not successful or takes place too slowly.
- the additional locking device is preferably connected to an energy store (52).
- this can be a mechanical energy store (52) which, for example, includes a tensionable drive means.
- the energy store (52) can preferably be charged by moving the actuating pawl (22), in particular by moving the actuating pawl multiple times. This ensures that the energy that is required for the remainder of the closure of the valve flap (32) is not drawn from a movement that is generated by the pressure difference force (F), but instead, for example, from regular door operation outside of a fire.
- the energy store (52) can thus be precharged before a fire occurs.
- the energy store (52) can particularly preferably support a first actuation of the additional locking device (50) in the fully charged state and at least one further actuation of the additional locking device (50) without an intermediate charging process.
- a particularly safe execution is achieved when the energy storage (52) in full charged state supports at least five or more consecutive actuations without intermediate charging processes.
- FIG. 12 shows an example of a door leaf (12) and a locking fitting set (60), which can be used individually or together to form a locking body according to the present disclosure.
- the locking fitting set (60) can also be used with another door leaf, for example an existing door, on which an opening (30) is made separately.
- the door leaf (12) can also be combined with other locking means in order to achieve the claimed function of the locking body (10) according to the present innovation.

- an additional latch designed as a panic latch lock (38) with a lock case (19) and a sliding body (39), and a coupling mechanism (40) for connecting the sliding body (39) to the push rod (39') .
- thrust rod and “thrust body” refer to structural means whose function is familiar to those skilled in the art. They include translationally movable devices for the transmission of forces that are stiff in at least one load direction, for example rods, rails, bolts, cables, chains and the like. However, they also include devices that can be moved partially or completely in a rotational manner.
- the locking fitting set also includes a valve device (28), which is designed as a valve flap (32) and can be inserted into an opening (30) in the door leaf.
- a release mechanism (42) is formed by connecting the thrust body (39) and the push rod (39'), which is operatively coupled to the locking fitting (18) and opens the valve device (28) so that the Valve device (28) when opening the door leaf causes a temporary pressure equalization when there is a pressure difference across the inside and the outside of the existing door.

- the locking fitting set (60) includes a panic latch lock (38) which is designed as a mortise lock with a lock case (63). This enables a modular structure and facilitates the assembly of the second latch on the door leaf (32).
- the locking fitting set (60) can also include at least one additional panic latch lock (38) and/or at least one additional deadbolt lock, which is/are operatively coupled to the locking fitting (18) in the intended installed state.
- the door leaf according to the preferred embodiment in Figure (12) is the door leaf of a pivoting door (11), a pivoting window or a pivoting flap.

- the sliding body (39) of the panic latch lock (38) is accommodated and possibly guided in the sliding body channel (62).
- the door leaf can also have a connecting cavity (63) in an area between the push rod channel (61) and the push body channel (62).
- Another part of the coupling mechanism (40) can be accommodated and possibly guided in this connecting cavity, in particular a bridge or a spacer, via which the push body (39) and the push rod (39') are operationally connected to one another in the intended assembled state.
- the further part of the coupling mechanism (40) is designed as a coupling linkage, which here has the shape of a parallelogram.
- the coupling linkage can be connected in any way to the push rod (39') on the one hand and to the push body (39) on the other hand, for example by welding, gluing, screwing or riveting.
- the coupling linkage can also be designed as a single rod, as a flat body (see FIG. 1), or as a multiple linkage with a different shape.
- force deflections, gears, cable pulls or chain pulls can also be considered.
- All of the described components of the locking fitting set (60) and the door leaf (12) according to FIG. 12 can also be a component of the closing body (10) individually or in any combination.
- all means attached to the door leaf (12) that contribute to the locking function can be a part of the locking fitting set (60), ie in particular the door closer (26), the flap closer (36), the opening limiter (44), the additional Closing device (50), the energy store 52, the locking mechanism (46) and the hinge straps (14, 34).
- the release mechanism (42), in particular the panic latch lock (38), can preferably comprise at least one sliding body (39) which can be or is coupled to the locking fitting (18) in an operative manner.
- the coupling can be done in any way.
- a separate gear can be provided be (not shown), which is connected to the actuating pawl (22) or a pawl receptacle (41) of the locking fitting (18) and transmits a movement of the actuating pawl (22) or the pawl receptacle (41) to the thrust body (39).
- the locking fitting (18) can alternatively or additionally have a push rod (39').
- the gear can be connected to a push rod (39') of the locking fitting (18) and transmit a movement of the push rod (39') triggered on the basis of the movement of the actuating pawl to the push body (39).
- the push rod (39') can, in particular, be moved corresponding to a retraction movement of the first latch (21). Alternatively or additionally, it can be moved corresponding to a movement of the actuating pawl (22) or the pawl receptacle (42).

- the hinge side of the valve flap (32) can be provided at any angle on the closing body (10).
- the hinge side can be at the top edge of the opening (30), at the bottom edge of the opening (30) or on a side edge of the opening (30).
- FIG. 1 The design according to FIG. 1 is particularly preferred.
- hinge side is provided on a lateral edge of the opening (30), in particular on the edge of the opening (30) that is remote from the locking fitting (18).
- the second latch (38), in particular the panic latch lock, can be provided on any edge of the opening (30).
- the panic latch lock is preferably provided opposite the hinge side.
- a second latch, in particular a panic latch lock can be provided on a side that is essentially transverse to the hinge side.
- the locking body (10) can include at least one additional panic latch lock (49) and/or at least one additional bolt lock (not shown), which is/are operatively coupled to the locking fitting (18) (cf. FIG. 12 below).
- the additional panic latch lock (38) and/or bolt lock can be part of the lock fitting set.
- the additional panic lock (49) can be connected to the door lock (20) via the sliding body (39') in an operative manner.
- the additional deadbolt lock can be connected to the door lock (20) in an operative manner via an additional mechanism.
- the forend (25) can rigidly connect the door lock to the at least one additional panic latch lock (49) and/or at least one additional bolt lock in order to provide a force support for the thrust body (39') and/or the additional mechanism and/or the push rod (39 ) to guarantee.
- the closing body (10) can have a first valve flap (32) and at least one further valve flap (32).
- the further valve flap (32) can be arranged separately in a further opening of the door leaf (12). Alternatively, it can be arranged as a cascaded valve flap (32) in an opening which is arranged in the first valve flap (32) (cf. dashed representation below in FIG. 1).
