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 passages of a room, wherein there is a pressure difference between the interior and the exterior of the room.
  • a valve device is provided on the closing body, which brings about a temporary pressure equalization when the closing body is opened or closed.
  • the disclosure relates in particular to a fire door.
  • the room is in particular an escape route room of a civil building, further in particular a stairwell.
  • the disclosure further relates to a locking fitting set 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 inside and the outside of the room, which is caused by the closure are separated from each other. This has particularly negative consequences in the event of a fire.
  • Escape routes in buildings can include several rooms separated by locks and must ensure safe escape for at least 90 minutes in the event of a fire.
  • smoke pressure systems pressurize escape route rooms, especially stairwells in buildings.
  • the smoke pressure systems are automatically switched on by smoke sensors.
  • the smoke pressure systems constantly pressurize fresh air into the escape route room and create an overpressure in it compared to adjacent rooms (usable areas). This prevents (further) smoke from the adjacent room from entering the escape route room or stairwell.
  • smoke that has already accumulated in the escape route room is preferentially expelled upwards.
  • closing bodies such as doors that close the entrances or access openings to and from the escape route room or stairwell should not exceed a door opening force of 100 N.
  • a door opening force of 100 N is already so high that younger people cannot definitely exert it.
  • the door opening force that a person has to apply 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 For conventional doors with an area of around 2 square meters, the pressure in the escape route is therefore limited to 30-40 Pa (Pascal). However, this pressure is often not enough to achieve the required 2 m/s in the door cross-section. In practice, therefore, significantly higher pressures occur in the escape route. Thermal effects can also cause the pressure in the escape route to be at least locally well above the intended 30-40 Pa, which leads to correspondingly higher pressure difference forces on the doors.
  • the doors of the usable areas on upper floors open onto the stairwell. So 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 excess pressure in the stairwell, whereby the door opening force can be well above the specified limit of 100 Newtons and can correspond to up to 2000 Newtons due to the pressures that actually occur in practice. A single person is often unable to generate such a door opening force.
  • a door closing system is known in which a door is held in the position in which it was last opened until a control signal is received from either a detector arrangement or a power cut-off 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 remainder of the way.
  • the 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 outlet opening, which connects the escape route with the environment and whose flow resistance can be varied by means of a preferably electrical actuating device.
  • a pressure sensor is provided in the escape route, which measures the pressure at least in the escape route at a 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 actuating 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.
  • the 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 to an opening in a wall, ceiling or floor.
  • the sealing unit is adapted in shape and size to the opening and is at least partially provided with a flexible material.
  • the passage opening is provided for people and/or with a lead-through opening for equipment, fire-fighting equipment and the like.
  • the passage opening and/or the lead-through opening can be at least partially covered.
  • the Sealing unit is provided with a tensioning or clamping frame.
  • a combined drive device for two pivoting door leaves is known, which are moved by a motor and arranged at the ends of an anteroom for a gas-tight lockable room of a nuclear reactor.
  • Each of the door leaves includes a pressure equalization valve designed as a conical plug.
  • the doors can only be moved in a coordinated manner so that at least one of the doors is gas-tight at any time.
  • a push button arranged separately in the room closes one door, closes the valve there and then opens the other door. Before the other door opens, the valve there also opens, which brings about permanent pressure equalization.
  • the EP 2 337 912 B1 describes a high-rise building with a stairwell, an air supply shaft, inlet openings that connect the air supply shaft to the stairwell and a pressure system to keep 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 sealed by at least one bulkhead. vertically divided into several sub-rooms. Each bulkhead has a door that allows passage from one sub-room of the stairwell into the adjacent sub-room. This ensures a more homogeneous pressure in the event of a fire for relatively high-rise buildings, for example even above 120 m total height, and in any case above approx.
  • a flow speed in accordance with the standard for example greater than or equal to 2 m/s, should be ensured between the stairwell and the usage unit on the fire floor.
  • the shaft effect for normal operation and also for the event of a fire in the building therefore does not need to be taken into account.
  • the JP 2019-044576 A wants to enable the elimination of any pressure difference just by opening a doorknob and protection with a small force.
  • a pressure difference relief mechanism is mounted on an opening, which in turn is provided on a fire door.
  • the opening is opened with a side surface of the fire door.
  • the pressure difference relief mechanism is provided with a movable body that can be inserted into or removed from the opening.
  • a side surface of the movable body is formed flush with a side surface of the fire door.
  • the movable body is connected by a rotary shaft which is attached to a side surface the fire door is installed in a position offset from the fire door, is rotatably attached to the fire door.
  • the movable body is provided with a latch for attaching the fire door to a fire block and another latch for attaching the movable body to the fire door.
  • the latches are connected to a doorknob via a gear drive mechanism and are released by the door opening operation of the doorknob.
  • the rotary shaft is always pressed in the closing direction of the movable body by a drive device.
  • the JP H04 102691 A aims to temporarily relieve a room pressure difference and to facilitate the opening/closing of a door.
  • the door is provided with a frame body for inserting a closure plate which can be moved up and down in the frame body.
  • air communication openings are provided, both in the frame body and in the closure plate and by moving the closure plate up and down.
  • the air communication openings of a door are usually closed by the part of a closure plate where there is no air communication opening, so that the pressure difference between the inside and outside of a room can be maintained.
  • a handle lever is turned 90 degrees to lift the closure plate upwards via a rod, and the Connection holes of the shutter plate are placed on the connection holes of the door for air circulation through ports.
  • the pressure difference between the inside and outside of the room can be reduced to facilitate the opening/closing of the door.
  • the pressure difference between the inside and outside of the room can be maintained again. This can facilitate the opening/closing of the door and also maintain the pressure difference between the inside and outside of the room.
  • a door or window element which comprises a door or window wing.
  • a pressure compensation mechanism and a handle with an exposed handle end region are provided. In a first position of the exposed handle end region, which is assumed when the handle is not actuated, the pressure compensation mechanism is in the inactive state. When the handle is fully actuated in a second position of the exposed handle end region, the pressure compensation mechanism is in the active state.
  • the JP H07 259407 A also wants to eliminate any pressure difference just by opening a doorknob and protecting with a small force enable.
  • a pressure difference relief mechanism is attached to an opening provided on a fire door. The opening is also opened with a side surface of the fire door.
  • the pressure difference relief mechanism is provided with a movable body that can be inserted into or removed from the opening. A side surface of the movable body is formed flush with a side surface of the fire door.
  • the movable body is rotatably attached to the fire door by a rotary shaft installed at a position offset from a side surface of the fire door.
  • a first latch for fastening the fire door to a fire block and a second latch for fastening the movable body to the fire door are provided in the movable body.
  • the two latches are connected to a doorknob via a gear drive mechanism and are released by the door opening operation of the doorknob.
  • the rotary shaft is always pressed in the closing direction of the movable body by a drive device.
  • CN106703649A discloses a door leaf of a pivoting door, wherein the door leaf has at least one opening to which a valve flap can be attached.
  • the aim of the innovation is therefore to avoid the disadvantages of the state of the art and to create a closing body such as a door, a window or a flap, which can also be opened in the event of pressure differences above the closed closing body or in the event of a pressure difference between the outside and the inside of the escape route room. can be opened as evenly as possible.
  • Another task of the innovation is to show an associated locking fitting set and an associated door leaf.
  • the object is achieved by a closing body according to claim 1.
  • 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 pre-tensioning means.
  • the valve device causes a temporary pressure equalization depending on the requirement.
  • the release mechanism allows the valve device to open. Whether the opening actually takes place can depend on the external conditions, in particular whether there is actually a sufficiently high pressure difference. This avoids unnecessary openings of the valve device when there is no need for this.
  • the opening movement of the valve device is preferably caused by a pressure difference force resulting from the pressure difference between the interior and the exterior
  • the opening movement can in particular be caused 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 fallen 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 using the valve device no longer leads to an increase in the door opening force or a forceful impact of the locking body due to the pressure. Instead, the valve device and the pressure equalization it enables temporarily reduce the pressure difference force in order to enable unhindered escape.
  • the innovation after the escape has taken place, the valve device closed again so that the pressure difference can build up again.
  • the locking body When activated, the locking body opens a valve device arranged in the door leaf, so that pressure equalization occurs almost simultaneously with the door opening or with minimal lead time. This eliminates the force resulting from the pressure and the locking body can be opened largely independently of the pressure difference.
  • a smoke pressure system for example, can be operated at higher pressure, which improves fire safety without representing an obstacle for people trying to escape. With higher pressure, the speed of 2 m/s is then regularly reached in the door cross-section, thus improving fire safety.
  • Such a closing body can be used with both overpressure and negative pressure.
  • Doors, windows or flaps are usually the bodies used to close openings of escape routes.
  • the closing body is designed as a pivoting door, pivoting window or pivoting flap.
  • a locking fitting in particular a mechanical, electronic, pneumatic and/or hydraulic Locking fittings are provided for the locking body.
  • locking bodies can be locked in a suitable manner.
  • such locking fittings also allow external control of the locking mechanism.
  • a control unit that is designed to be processor-controlled, for example, such a locking fitting can be controlled, for example to enable or execute or prevent an opening or closing movement.
  • the necessary force can be applied with such systems to lock the locking bodies.
  • the valve device can also be designed accordingly in order to control it in a suitable manner.
  • the release mechanism is a mechanical, electronic, pneumatic and/or hydraulic release mechanism that opens the valve device and, if necessary, also closes it.
  • the release mechanism can in particular be designed to open or close the valve device depending on the requirement, ie in particular only when there is a sufficiently high pressure difference. In other words, 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 locking body in an actuating manner.
  • the actuating coupling means that an actuation of the locking fitting, for example the manual movement of an actuating latch or the controlled activation of an actuator of the locking fitting, is converted into a coupled opening of the valve device via the release mechanism.
  • the actuating coupling automatically causes the valve device to open when the locking fitting is actuated. No separate additional actuation is therefore required to open the valve device.
  • a person attempting to escape in an emergency does not need to actuate a separate opening means in order to reduce the pressure difference across the locking body. Rather, this happens automatically as a result of the actuating coupling with the locking fitting.
  • the closing body comprises at least two latches, a first latch which holds the closing body in a closed state relative to a frame, and a second latch which holds the valve device in a closed state relative to the closing body.
  • the release mechanism and in particular the preferably The mechanism used opens two door latches, for example, one to open the door and a second to release the valve device, such as the flap.
  • the flap preferably only opens when there is excess pressure.
  • the flap also closes automatically when the pressure drops. This means that the regulations for fire and smoke protection can be met.
  • a pressure sensor which controls the release mechanism.
  • the release mechanism reacts to the control signals generated by a pressure sensor. This allows the valve device to be controlled when the pressure, for example in the pressurized space, becomes too high and exceeds a predetermined threshold value.
  • the release mechanism has a control means which opens the valve device before the locking body.
  • the control means can be designed in any way.
  • it can be formed by a gear which causes a second latch which secures the valve device to open earlier than a first latch which secures the locking device when the actuating latch moves.
  • Such a gear can be arranged between a sliding body which moves the second latch and a locking fitting. of the locking body.
  • the means can be formed in that the first latch and the second latch are designed with different (effective) tongue lengths, so that with essentially the same movement speeds, the second latch falls below the release threshold earlier than the first latch.
  • a device that first carries out the pressure equalization before the locking body can be opened. This can be done, for example, by a delayed release of the locking fitting.
