    The invention relates to a closure element, in particular a door leaf which has a surface element and is movably displaceable with respect to a door opening of a building in order to selectively open or close it.
    Typically, the movable flat closure element is the door leaf of a pivoting door; but it can also be, for example, the movable, flat closure element of a sliding or lifting door. In this document, the term “door” also includes objects that are usually referred to as “gate”.
    When a door in a building is closed, it is not always desirable that air exchange between the two sides of the flat closure element is completely prevented by the flat closure element. Above all, in order to maintain good air quality in otherwise non-ventilated rooms, ventilation through the door is desirable even when the flat closure element is closed.
    A short introduction to the state of the art:
    The documents AT 510200B1, JP 2000110455A, DE 19646383A1, DE 202014101295U1 and WO 9840598A1 show pivotable door leaves which have an air duct on the lower end face which connects the two sides of the door leaf with one another. So that the rooms on the two sides of the door are well separated from each other in terms of light and sound despite the air duct, the air duct is strongly curved and designed with sound-absorbing material as a boundary wall. The air duct cannot be closed.
    EP 2629027A1 shows a door leaf whose lower edge line is formed by a combination of two U-profiles extending along the edge line with the profile side open at the bottom. The upper U-profile is so wide that the lower U-profile can be pushed into it from below and fixed at a selectable height. The profile flanks protruding from the lower U-profile below the upper U-profile have a grid of openings. In this way, an intentional constant leakage of the door leaf is achieved, even when the door is closed.
    The documents EP 2664741A1, CH 701232A1, EP 1498569A1, EP 1936097A1 and EP 2824271A1 show pivoting door leaves with a bottom seal, which is automatically lowered by closing the door leaf - that is, closed - and is automatically raised by opening the door leaf. A non-closable, curved air duct equipped with sound-absorbing material is arranged in or on the floor seal, which bridges the floor seal and therefore allows a small air flow between the two sides of the door leaf even when the floor seal is lowered without transmitting light and sound. According to EP 2664741A1 belonging to the last-mentioned group of documents, a fan is arranged in the air duct which, when switched on, forces an air flow in the air duct. The fan can be connected to a controller that switches it on or off depending on the climatic conditions in the building.
    According to a design according to EP 1498569A1, which is also part of the last-mentioned group of documents, the opening of the air duct can be provided with an elastically deformable sealing lip which essentially only allows air flow in one direction and offers relatively very good insulation against sound and light.
    The documents DE 2657279A1 and DE 3124106A1 describe pivotable door leaves with a lowerable bottom seal for particularly high gaps between the door leaf and the floor. Even when the door leaf is closed, there is the possibility of lifting the bottom seal, namely by operating a handle provided separately on the door leaf. A good exchange of air is then possible between the rooms on both sides of the door leaf, but the rooms are then connected to one another in a disruptive manner in terms of sound and light.
    According to the documents EP 1944457A2, DE 102014106702A1 and EP 2664741A1, the position of a lowerable floor seal can be changed by an actuator which can be controlled by a building control system. A “building control system” in this sense means a system of sensors, controls and actuators which, as intended, measures conditions in the building and, depending on this, influences the functions of devices.
    DE 1254323B shows a design for a ventilation slide which automatically opens or closes openings through which a room can be ventilated only depending on its own temperature. For this purpose, the slide has two long strips that lie flat against one another and each have a grid of openings. The two strips are made of different materials with very different coefficients of thermal expansion. Depending on the temperature and the dimensions of the two strips, which are dependent on this, the through bridges on both strips are either aligned with one another or they are shifted from one another.
    Especially in houses with automatically pressure-ventilated staircases in the event of a fire, it comes in connection with pivoting door leaves that must be automatically moved by a locking device from the open to the closed position, and are pivoted from the room adjoining the staircase to the staircase , to problems. So that in the event of a fire in the building no smoke flows into the stairwell from an adjacent room - which would block the possibility of escape through the stairwell - in the event of a fire the stairwell is pressurized slightly by a fan (typically 50 Pa). Closer drives with a very high closing force are required so that the doors to the adjoining rooms can be closed automatically against this excess pressure. This closing force often has to be quite high even if the door leaves are equipped with a conventional lowerable bottom seal that is only lowered when the door leaf is closed. The strong closing force of the closer drive can, however, represent a great danger for people who have to open the door in order to escape into the stairwell, since they have to overcome this force in order to open the door. For smaller children or for people with disabilities, this can make it impossible to open the door and subsequently escape from the building.
    Even with doors in which the movable flat closure element is brought into the closed position or away from it by a movement parallel to its own main surface, a strong air pressure difference between the two sides of the closure element can interfere with the mobility of the closure element when opening or closing .
    The inventor has set himself the task of improving a closure element which is flat and can be moved relative to a door opening of a building in order to selectively open or close it. The aim of the improvement is to reduce those forces which can counteract the closing or opening movement of the closure element due to an air pressure difference or an air flow at the door opening.
    In this case, an extremely high liftable bottom seal should not simply be used because that would be optically unfavorable and the mechanical stability - especially with regard to burglary protection - would weaken too much.
    According to the invention it is proposed for solving the problem that the flat closure element has a channel and a closing device, the channel is arranged away from the surface edges of the closure element and the movable flat closure element penetrates normal to its surface, and the closing device through a drive can be moved back and forth between a position closing the channel and a position opening the channel.
    With a correspondingly large design of the cross-sectional area of the channel (or the sum of the cross-sectional areas of several such channels) so when the closing device is in the open position, such a large air flow through the closure element is possible that the air pressure difference between the two sides of the closure element inevitably becomes quite low. As a result, the air pressure difference cannot exert such great forces on the closure element that they could greatly interfere with the opening or closing movement.
    Preferably, the drive that drives the locking device can be triggered by actuating the handle of the movable, flat locking element to move the locking device into the position that opens the channel.
    Without restricting the inventive concept, the invention is described below using the example of a pivoting door in which the movable flat closure element (door leaf) has a bottom seal. As a result of the channel provided in the closure element according to the invention, air can flow not only from one side of the closure element to the other side of the closure element when the bottom seal is raised below the movable flat closure element, but also through the channel.
    The invention is illustrated on the basis of highly stylized drawings of movable flat closure elements according to the invention, which are exemplarily designed as pivotable movable flat closure elements with a lowerable bottom seal: , a section of a first closure element equipped according to the invention with a lowerable bottom seal, which is in the raised state. Fig. 2: shows, in the same way as Fig. 1, the closure element of Fig. 1 with the bottom seal lowered. 3: shows in an oblique view a second movable, flat closure element according to the invention with a lowered bottom seal.
    The flat closure element 1 according to FIG. 1 has two surface elements 2, 3 lying parallel to the plane of the closure element 1, which delimit a cavity between them, in the lower region of which there is a vertically guided movable closing device 4 and a drive 5. The drive 5 is used to raise or lower the locking device 4. On its lower end face, the locking device 4 has a seal 6, which is typically designed as a soft rubber profile and, when the locking device 4 is lowered, rests on the base 7 of the space in which the flat locking element 1 is pivotably arranged.
    The closing device 4 is essentially a hollow profile, the profile direction of which is aligned horizontally and parallel to the plane of the closing element 1.
    It is provided that the closing device 4 and the surface elements 2, 3 on the facing surfaces have openings 8, 9, the openings 8 in the closing device 4 then align with the openings 9 in the surface elements 2, 3 when the closing device 4 is raised, which means that the bottom seal is open.
    Said alignment of the openings 8, 9 forms a channel 10 which penetrates the closure element 1 normal to its plane and is open on both sides of the closure element 1, so that the channel 10 thus enables air flow 11 through the closure element 1 through the closure element 1 when the closure device 4 is raised. This air flow 11 is a valuable addition to the air flow 12 in the gap between the seal 6 and the substrate 7, which is otherwise usual when the closing device 4 is raised.
    For reasons of strength, it is advisable not to provide a single large opening 8, 9, but rather a number of webs of the locking device 4bzw. of the surface elements 2, 3 separate smaller openings 8, 9. The respective openings 8 or 8 are preferred. 9 arranged horizontally next to one another because the length of the locking device 4 is thus used well and the locking device 4 need not be too high.
    As can be seen in Fig. 2, the cross-sectional areas of the openings 8, 9 of the closing device 4 and surface elements 2, 3 do not overlap when the closing device 4 is lowered, so that when the closing device 4 is lowered, no air flow through the closing element 1 is possible. As an alternative to this outlined design, a small residual overlap of the cross-sectional areas of the openings 8, 9 could be allowed and thus, as with designs from the prior art, with the closure element 1 closed and the closure device 4 lowered, a small residual ventilation through the closure element 1 could still be allowed.
    The drive 5 can be designed in the same way as those controllable actuators that are already being used to raise or lower lowerable floor seals as a function of conditions. Ideally, the drive 5 can be controlled by a building control system so that it automatically raises (i.e. opens) or lowers the locking device 4 depending on ventilation requirements in the building.
    According to an advantageous embodiment, the movable flat closure element 1 is equipped with a sensor and a control, by which actuation of the handle of the closure element 1 is detected and then the drive 5 is controlled so that it lifts the locking device 4. This ensures that there is no disruptive air pressure difference between the two sides of the closure element 1 either during the closing process or during the opening process of the door.
    The exemplary movable, flat closure element 13 according to the invention sketched in FIG. 3 is pierced by a channel 14 provided as a flow path for air. The channel 14 can be closed by a closing device 15 which is formed by lamellae which can be pivoted about axes parallel to their longitudinal direction. In this example too, the closure element 13 has a seal 16 which serves as a bottom seal and, according to an advantageous embodiment, when the seal 16 is lifted, the closure device 15 is brought into the open position. With the lowering of the seal 16, the closing device 15 is brought into the closed position.
    The coupling of the pivoting movement of the slats of the closing device 15 and the vertical movement of the seal 16 can be enforced by a mechanical translation between these moving elements. The coupling can, however, also be formed without a mechanical connection, only by a common control. For this purpose, the control always switches on the drive for the closing pivoting movement of the slats whenever it switches on the drive for the upward movement of the seal 16. The pivoting movement of the slats - and thus the opening and closing movement of the closing device 15 - can also be controlled independently of the movement of the seal 16 forming the bottom seal, for example simply depending on whether the handle of the surface element 13 is actuated or not.
    Pivoting slats as a switchable closing device 15 for a channel 14 through the movable, flat closing element 13 are only to be regarded as an exemplary closing device. As part of the professional work, a variety of switchable locking devices for a channel are conceivable. A good possibility is, for example, to arrange a plate on the inside of two surface elements parallel to the plane of the flat closure element of a flat closure element designed as a hollow body, which has a hole pattern and which can be displaced parallel to the plane of the flat closure element. In said surface elements of the closure element, a grid of holes is also arranged with the same grid dimension as on the plates. Depending on the position of the plates in relation to the surface elements, the holes of the hole grids lying against one another are aligned or not aligned, with the result that the duct provided for the air flow is open or not.
    Structures as in Fig. 1 and Fig. 2, in which the channel 10 in the movable flat closure element 1 optionally closing the closing device 4 is formed directly as part of the lowerable bottom seal, are mechanically less complex than the last discussed construction methods.
    Structures in which the opening and closing of the movable flat closure element penetrating channel 14 by a separate locking device 15, which is independent of the seal 16 used as a bottom seal, are mechanically more complex. For the latter, it is easier to realize large channel cross-sections, to arrange the channel further away from the seal 16 and to orient the opening or closing movement of the closing device 15 differently than parallel to the movement of the bottom seal.
    The considerations on the construction of a movable closure element with a bottom seal described with reference to the drawings are also applicable when the closure element has a movable seal guided relative to it, which does not bridge a gap from the closure element to the floor of the building but a gap to another part of the building in the vicinity of the closure element.
