Description

introduction

The present application relates to an openable room termination device according to the preamble of claim 1. Furthermore, the present application relates to a method for opening a room termination device according to the preamble of claim 12.

The room termination device, which can be formed in particular by a light dome for a roof, comprises an upstand and a room termination element. Room termination devices of this type are provided, in particular, in hall roofs in sports halls or factory buildings. The curb is typically connected directly to the respective structure on which the space termination device is active, the curb being able to protrude, for example, over a surface of a respective adjacent component. The room closure element can be formed, for example, from a transparent material, in particular translucent plastic, and extends over a certain opening area. This opening area is laterally delimited by the curb, so that the opening area is "covered" all around the curb by placing or placing the space closure element and the space assigned to the space closure element is closed. The curb can in particular have a circumferential edge, with a sealing surface of the edge interacting with the space closure element (if the latter is in a closed position) at least rainproof, preferably airtight. In particular, the sealing surface can be formed on an upper end face of the curb and can be arranged completely in a sealing plane.

The room termination device further comprises at least one drive and at least one transmission device. The drive is suitable for exerting an opening force by means of which the space closure element can be opened directly or indirectly from its closed position. The transmission of the power of the drive to the space closure element takes place by means of the transmission device. The space closure element can in particular be arranged on the curb in such a way that it can be lifted off the curb in order to expose a flow cross section between the room and the surroundings. In this way, the room closed by means of the room termination device can be ventilated.

The room closing element can be converted into an SHEV position, whereby the flow cross-section between the room to which the room closing element is assigned and an environment against which the room closing element closes the room is maximally released when the room closing element is present in its SHEV position. In particular, the flow cross-section when the room closure element is present in its RWA position can have the size of a cross-section of the curb in the area of the sealing plane. As an alternative or in addition, the flow cross-section can be released in its SHEV position as far as it would be released if the room termination device were not provided with the room termination element.

The ability of the room termination element to be moved into the SHEV position is necessary in order to be able to ensure ventilation of the room in an emergency situation, in particular in the event of a fire in the room. This applies in particular to those room termination devices which are arranged in a roof. In the event of a fire, flue gases accumulating in the room can escape through the open room closure devices and thus extend the time window for escape from the associated building.

State of the art

Room termination devices of the type described above are already known in the prior art. It has proven to be problematic here to ensure reliable opening of the room termination device in an emergency. The opening process must meet particularly high requirements in terms of reliability and speed. In particular, the room closure element must also be able to be moved into its RWA position if it is loaded on its upper side with a load, for example a snow load. The opening must also be possible in the presence of the load within a predetermined period of time, for example 60 seconds.

The expenditure on equipment to comply with these criteria is particularly great in relation to what a room termination device has to achieve in normal operation. This means that the dimensioning of the drive, in particular, is largely determined by the requirements in an RWA situation. The available power of the drive is only used in fractions in normal operation. Due to these circumstances, the known room termination devices are comparatively complex in their construction, without this being necessary for normal use.

task

The present application is therefore based on the object of providing a room termination device which is constructed more efficiently in comparison with the prior art.

solution

The underlying object is achieved according to the invention by means of a room termination device with the features of claim 1. Advantageous refinements result from subclaims 2 to 11.

According to the invention, the transmission device comprises at least one elongated swivel arm which is mounted on the room termination device, in particular on the curb, so as to be pivotable about a swivel axis. The swivel arm interacts with the space closure element in a force-transmitting manner by means of at least one coupling means, the coupling means being arranged at a distance from the swivel axis. The drive also acts on the swivel arm in such a way that an engagement point of the drive on the swivel arm and the swivel axis are spaced apart from one another, forming a lever arm. This has the effect that a drive force applied by means of the drive causes a torque about the pivot axis, by means of which the pivot arm can be pivoted about the pivot axis. The swivel arm is typically arranged on an edge of the curb, in particular on the inside of a side wall thereof, the swivel axis preferably being associated with the side wall. For example, the swivel arm can be connected to the curb by means of a mounting bracket, the swivel axis being formed on the mounting bracket. If the space closure element is in its closed position, the swivel arm is preferably located completely within the space closure device, that is to say on this side of the sealing plane of the curb. In this position, the swivel arm is not visible from the surroundings.

The transmission device is advantageously formed by the swivel arm, so that the transmission device is formed in one piece, the swivel arm being connected directly both to the curb and also directly to the space closure element. The drive preferably acts directly on the swivel arm. It is conceivable here that the space termination device comprises two transmission devices, which are each formed by a swivel arm are each assigned to one of two opposite sides of the room closure element.

The space closure element preferably interacts with two swivel arms, which are each arranged on one side of the space closure element. The coupling means of the two swivel arms are then preferably located on a common axis which is arranged parallel to the swivel axis of the swivel arms. This has the advantage that, if the coupling means are configured with an axis of rotation, the axes of rotation of both coupling means of the swivel arms coincide or match, so that the space closure element can be rotated relative to the swivel arms about this (common) axis of rotation.

The present invention is based on the consideration of transferring the space closure element into its SHEV position by means of the action of gravity and thus independently of the drive used. For this purpose, it is necessary that the space closure element is inclined starting from its typically horizontally oriented closed position, so that the weight force acting on the space closure element receives a horizontal vector component. This can be used to move the space termination element laterally in relation to the curb and in this way to remove it as completely as possible from the curb, which is then completely released. The latter describes the SHE position of the room closing element, since the flow cross-section for the exchange of air between the room and the environment is maximally released.

In order to implement the above consideration, in the space termination device according to the invention, in comparison to the prior art, there is no direct pivoting of the space termination element by means of a drive about a lateral pivot axis which, for example, is assigned to an edge of the space termination element itself. Instead, the swivel arm on which the space closure element is mounted is pivoted. Here, the space closure element is only moved indirectly due to its coupling with the swivel arm, namely as a result of the swiveling of the swivel arm about its swivel axis. It is thereby achieved that the space closure element as a whole can be lifted off the curb and in this way a (vertical) distance can be created between the space closure element and the curb. In particular, by means of the configuration according to the invention, it is possible to lift the space termination element completely (that is to say all the way round) from its sealing seat and thereby to open up a circumferential flow cross section.

The creation of the distance between the space closure element and the curb helps the space closure element to move freely relative to the curb, in particular as a result of an acting weight force, it can "slide" to the side without colliding with the curb. In this way, the room termination element can be transferred to its SHEV position in a particularly simple and rapid manner. There is no need for a specially dimensioned drive, since the drive does not actually transfer the room closure element to the SHEV position. The latter is only required to transfer the space closure element into an intermediate position, from which it can be moved under the action of gravity. When present in the intermediate position, the space termination element is typically lifted off the curb and is at least slightly oriented at an angle to the horizontal. The swiveling movement of the swivel arm can particularly well help to bring the space closure element arranged on the swivel arm into an oblique position, from which the transfer into the SHEV position can take place.

In a particularly advantageous embodiment, the space closure element comprises at least one movement frame, by means of which at least one surface part of the space closure element is movable, in particular translationally displaceable, relative to the swivel arm. The movement frame is preferably connected directly to the swivel arm by means of the at least one coupling means and is in this way firmly connected to the swivel arm. A movement of the movement frame as such relative to the swivel arm is advantageously - if at all - only possible in the form of a rotation about an axis of rotation, with the movement frame being connected to the swivel arm by means of the coupling means. This will be dealt with separately below. By means of the movement frame itself, movement of the surface part, which can be a translucent coupling element, for example, is now made possible relative to the swivel arm. In particular, the movement frame can have at least one rail system, preferably in the form of a telescopic rail, by means of which the surface part can be moved in translation relative to the swivel arm.

This configuration makes it possible to move the surface part away from the effective area of the space closure element, so that the opening area of the curb is at least essentially, preferably completely, released. In other words, a flow cross-section that is at least essentially free can be released by means of such an embodiment by “pushing away” or “sliding off” the surface part corresponds to the opening area of the curb. Such a release is suitable for maximum opening of the opening area, as if there were no space closure element on the curb. After the surface part has moved relative to the swivel arm, the room closure element is consequently in its SHEV position. The described "pushing away" or "sliding" can be done particularly simply by means of the weight of the surface part.

Ventilation of the room closed off from the environment by means of the room termination device, in particular in the event of a fire, can be effected in the best possible way in this way. For this purpose, a complete pivoting of the space closure element by 90 ° or more and possibly against an acting weight force, for example caused by snow, as is required in the prior art, is no longer necessary. Instead, it is conceivable to only slightly lift the space closure element from its sealing seat in a first movement section and to set it slightly obliquely in relation to a horizontal in a second movement section, so that an inclined position of at least the surface part is obtained. By means of the movement frame, at least the surface part of the room closure element can then be moved laterally away (`` sliding ''), in particular under the sole effect of its weight, which has a lateral vectorial component due to the inclination, whereby the opening area of the curb is released and the room closure element finally in his RWA position.

In such an embodiment, the room closure element can therefore be moved into its SHEV position by moving its surface part relative to the swivel arm. In comparison to the prior art, this procedure requires only a clearly smaller drive, since it is not necessary to completely "flip" the space closure element, that is to say pivot it relative to the curb by more than 90 °. Furthermore, as an additional advantage, the transfer of the room termination element into its SHEV position can be carried out significantly faster in an emergency situation than the "turning over" of the respective room termination element known in the prior art. In particular, a stroke which is greatly reduced in comparison with the prior art is sufficient to transfer the space closure element into an oblique intermediate position and then into its SHEV position, since the complete turning over according to the prior art can be omitted. This is particularly advantageous if the drive is in the form of a pneumatic piston-cylinder unit or an electrical drive unit. Such a can the space termination element according to the invention are dimensioned significantly smaller than in the prior art.

The room termination device according to the invention is advantageously designed in such a way that the room termination element and the swivel arm are connected to one another when the room termination element is present in its RWA position. The connection can in particular exist in the scope of a movement frame which is connected directly to the swivel arm and with the aid of which a surface part of the space closure element is moved relative to the swivel arm. The existence of the connection between the space closure element and the swivel arm even when the space closure element is in its SHEV position has the advantage that it is possible in principle to transfer the space closure element back towards its closed position. It is therefore particularly advantageous if the room termination device is transferred to its SHEV position in a non-destructive manner.

In principle, such a space termination device is also particularly advantageous in which the surface part can be repeatedly moved between a normal position corresponding to the closed position of the space termination element and an emergency position corresponding to the SHE position of the space termination element. In this way, the room closure element can be brought back into its closed position particularly easily after it has been transferred to its SHEV position. This makes it possible, for example, for the room termination device to continue operating as intended in the event of a false alarm which triggers the transfer of the room termination element into its SHEV position and therefore of the area part into its emergency position.

Regardless of the design of the room closure device with a movement frame, it can also be particularly advantageous if the swivel arm is in its SHE position in its SHE position in a deflection position rotated about the swivel axis in such a way that the swivel arm extends beyond a sealing plane of the curb protrudes outside and is preferably oriented inclined to a horizontal. In other words, in this embodiment, the swivel arm is moved or pierces through the sealing plane of the curb in the course of the transfer of the space closure element from its closed position in the direction of its SHE position. As a result, the swivel arm is visible from an environment, at least when the room closure element is in its RWA position, since it is no longer completely "inside" the upstand, but at least partially protrudes beyond the sealing plane. This configuration is advantageous insofar as the swivel arm is suitable for lifting the space closure element beyond the sealing level of the curb, so that the space closure element can be lifted all the way out of its sealing seat and a distance between the space closure element and the curb can be created. In the course of this (lifting) lifting, the available flow cross-section is increased significantly, so that ventilation of the room can take place particularly well.

When using this construction, it is also advantageous if the space closure element comprises at least one latching means, which at least temporarily prevents movement of the surface part relative to the swivel arm. The latching means preferably acts at least until the swivel arm is in a deflected position. The latching means is used in particular to prevent a mechanically possible, but in the absence of an RWA situation undesirable transfer of the room closure element into its RWA position. Such a configuration is particularly advantageous in combination with a movement frame described above, which enables a translatory movement of at least one surface part of the space closure element relative to the swivel arm. The latching means prevents this movement by latching the flat part in such a way that a relative movement between the flat part and the swivel arm is prevented. By releasing the latching means, on the other hand, said movement is possible, so that the room closure element can be moved into its SHEV position. Such release can take place, for example (automatically) as a result of a fire alarm or by means of a manually operated manual control point. As long as the latching means is closed, the space closure element can be transferred to an intended open position in which the flow cross section between the curb and space closure element is released for normal ventilation.

In the application of the space termination device, it is also conceivable to control the transfer of the space termination element into its SHEV position by means of the deflection of the swivel arm, the transfer of the latching means being made dependent on the position of the swivel arm from a fixing position to a release position. A certain deflection of the swivel arm can thus automatically release the latching means, whereby, in particular as a result of the effect of gravity, at least the surface part of the space closure element is automatically moved translationally relative to the swivel arm and thus the space closure element is transferred into its SHEV position. However, this release does not take place if the swivel arm is only transferred to a "pre-position" in who has not yet released the locking means. In particular for the purpose of ventilation of the associated room, the swivel arm can consequently be transferred to any pre-position so that an unintentional movement of the surface part relative to the swivel arm does not occur, however the flow cross-section between the room and the surroundings is partially released and ventilation of the Space can take place. With such a configuration, it is conceivable that, for example in the course of a fire alarm, the drive is automatically controlled in such a way that it maximally raises the swivel arm or swivel arms so that they assume their deflected position, as a result of which the latching means is automatically transferred from its fixing position to its release position ,

Further developing the space termination device according to the invention, the at least one swivel arm can be moved from its deflected position into a rear position, in the presence of which at least a section of the swivel arm, preferably the entire swivel arm, is oriented in an inversely inclined manner relative to the sealing plane of the curb compared to the deflected position. This configuration has the technical effect that the surface part of the space closure element can only be moved from its emergency position back to its normal position by means of the weight of the surface part. This is due to the fact that by means of the transfer of the swivel arm or the swivel arms into the return position, the inclination of the room closure element with respect to its SHE position is changed, so that the surface part, under the action of a horizontal force component of its weight force, which is directed towards the swivel arm moved again in the direction of the swivel arm by means of the movement frame, so that the flat part is moved from its emergency position into its normal position. In this normal position of the surface part, the space closure element is suitable in the usual way to come into sealing engagement with the curb and in this way to establish the closed position of the space closure element. After all, in this embodiment, the space closure element can be moved into its emergency position and back again simply by moving the at least one swivel arm. Manual intervention, in particular on a roof surface in which the room termination device is installed, can be omitted.

The space termination element according to the invention further comprises at least one locking device by means of which the space termination element can be locked at least partially, preferably along part of an edge, against the curb. This locking means that the space closure element only partially out of its sealing seat in the course of the movement of the transmission device is lifted off - namely not particularly in the area of the locked edge - and is therefore inclined relative to the sealing plane. This configuration is particularly advantageous if the space-terminating element is arranged on the transmission device with the formation of an axis of rotation and would therefore basically be freely rotatable relative to the transmission device after it has been lifted off the curb. This could result in irregular states, which is why it can be advantageous to partially and temporarily lock the space closure element on the curb in the manner described, so that movement of the space closure element in the course of its transfer from its closed position to an open position, for example, can be controlled.

Advantageously, the swivel arm is connected to the space closure element, for example a movement frame of the same, at least when the space termination device is present in its closed position in its closed position. In this way, it is possible that the space closing element is rotated about the axis of rotation relative to the swivel arm in the course of an actuation of the drive and an associated lifting of the space closure element until a rotational coupling of the swivel arm to the space closure element takes place, which is the same rotation both components prevented from each other. The mentioned embodiment can be advantageous in particular in connection with a one-piece swivel arm, which is described at the beginning. The coupling of the swivel arm to the space termination element at a second coupling point or by means of a second coupling means can in particular be carried out simultaneously to unlock the locked edge of the space termination element from the curb. In this way, the position of the space closure element relative to the swivel arm is defined at all times during a movement of the swivel arm.

Such a configuration is particularly advantageous, in which the locking device interacts with an edge of the space closure element facing the drive, so that the space closure element first detaches from the curb on the side facing away from the drive when the swivel arm is raised. This configuration is particularly advantageous in order to achieve simultaneous locking and unlocking. This provides that the locking device is released at the exact moment when the space closure element is locked on the swivel arm, for example by means of a coupling means. By means of this procedure, the room closure element at no time free to swing uncontrollably to the swivel arm. Instead, a transfer of the space closure element from the curb to the swivel arm takes place to a certain extent in the course of the opening of the space closure device. The pivoting of the space closure element relative to the swivel arm is therefore checked and predetermined at all times. Before the swivel arm is coupled to a second coupling point, there is nevertheless a relative rotation of the swivel arm with respect to the space closure element, as long as the latter is locked to the curb.

Furthermore, such an embodiment of the space termination device according to the invention can be advantageous in which the swivel arm has at least one further coupling means by means of which the space termination element and the swivel arm can be connected to one another in addition to the first coupling means mentioned. The further coupling means is in particular formed at a distance from the first coupling means on the swivel arm, so that both coupling means can jointly absorb a pair of forces and therefore can transmit a torque. In this way, the space closure element can be locked in a rotationally fixed manner on the swivel arm, so that rotation of the space closure element, in particular around an axis of rotation formed on the first coupling means, is prevented. The further coupling means can act, for example, as a function of a deflection of the swivel arm, an abrupt shift in the center of gravity of the room termination device occurring in particular in the course of the transfer of the space closure element into its SHEV position when the surface part moves relative to the swivel arm. In the absence of the further coupling means, the latter can result in the spatial closure element being rotated overall about the axis of rotation relative to the swivel arm. This can be prevented by means of the further coupling means.

In procedural terms, the underlying object is achieved according to the invention by means of the method with the features of claim 12. Advantageous refinements result from subclaims 13 to 15.

It is already known from the prior art to move a room closure element of a respective room closure device by means of at least one drive, starting from a closed position relative to the respective curb, whereby the space closure element is at least partially lifted out of its sealing seat and a flow cross-section between the room, which by means of the Room locking device can be locked against an environment, and the environment is released. Furthermore, it is known to remove the space termination element from the curb in such a way that it is in its emergency position, in which the flow cross-section between the room and the environment is maximally released.

In the sense of the present application, the “removal” does not require complete disassembly or removal of the space termination element, but merely a movement of the space termination element at least in part away from the curb. In particular, it is known in the prior art to pivot a respective space closure element about a pivot axis arranged along a lateral edge of the associated curb, the space closure element being pivoted by at least 90 ° and finally turning over to take up the SHEV position. The connection between the room end element and the upstand on the swivel axis remains constant; nevertheless, the space termination element is "removed" from the curb in the sense of the present application.

1. a) Das Raumabschlusselement wird in einem ersten Bewegungsabschnitt ausgehend von seiner Schließposition zumindest im Wesentlichen unter Beibehaltung seiner Ausrichtung zumindest teilweise von seinem Dichtsitz abgehoben.
2. b) Das Raumabschlusselement wird in einem zweiten Bewegungsabschnitt relativ zu dem Aufsatzkranz verdreht, bis das Raumabschlusselement in einer Zwischenposition vorliegt.
3. c) Ausgehend von der Zwischenposition wird zumindest ein Flächenteil des Raumabschlusselements translatorisch relativ zu dem Aufsatzkranz bewegt, bis sich das Raumabschlusselement in seiner RWA-Position befindet.

The process according to the invention is now characterized by the following process steps:

1. a) The room closure element is at least substantially lifted from its sealing seat in a first movement section, starting from its closed position, at least substantially while maintaining its orientation.
2. b) The space closure element is rotated in a second movement section relative to the curb until the space closure element is in an intermediate position.
3. c) Starting from the intermediate position, at least one surface part of the space closure element is moved in translation relative to the curb until the space closure element is in its SHEV position.

The method according to the invention is particularly simple to carry out by means of the space termination device according to the invention. It offers the particular advantage that, compared to the prior art, the room termination element can be transferred to its SHEV position very quickly and, at the same time, with particularly little outlay on equipment. This also applies to the particularly small stroke that is effectively required to transfer the room termination element into its SHEV position. This leads to the advantage that the drive, which is responsible for the movement of the space closure element, does not have to be dimensioned in the same way as in the prior art, but can be made comparatively small and weak. After all, the drive is only for the movement of the Space termination element in charge in the two movement sections, while the translational movement of at least the surface part relative to the curb or the swivel arm can take place without the action of the drive, but is preferably operated solely by means of the weight of the surface part.

In the course of the transfer of the room termination element into its SHEV position, at least one surface part of the room termination element is advantageously moved exclusively in a translatory manner. This movement is then independent of a pivoting of the space closure element about the pivot axis, but acts solely on account of the slanted position of the surface part that has already been achieved. The translatory movement is preferably driven solely by a weight force at least of the surface part of the space closure element. On the one hand, such a configuration is particularly simple to carry out, since no separate drive is required for the flat part, on the other hand, it is extremely safe, since it takes place independently of a supply of electricity to the room termination device or other supply solely on the basis of the acting weight.

Further developing the method according to the invention, the space closure element is transferred from its intermediate position into its SHEV position exclusively by the action of gravity. This has already been explained above. This type of operation of the room termination device has the particular advantage that it can be carried out without current and is therefore particularly reliable in an emergency situation.

Furthermore, such a method is particularly preferred in which the room closure element is transferred from its SHE position back to its closed position solely by the action of gravity, preferably at least the surface part of the room closure element in this way from one with the SHE position of the room closure element corresponding emergency position can be moved into a normal position corresponding to the closed position of the room closure element. It is not critical here that the room closure element immediately returns to its closed position. Instead, it is more advantageous if the space termination element is first transferred to a second intermediate position. In this procedure, in particular, no additional drive is required to operate the room termination device in order to ultimately move it back into its closed position, which can be easily reached starting from the second intermediate position.

As already explained above in connection with the space termination device, it can be particularly advantageous if the space termination element during of the first movement section, at least partially, preferably along an edge of the curb, is locked to the curb, so that the space closure element is only partially lifted from the curb during the first movement section. This locking means that the room closure element - starting from a horizontal orientation in its sealing seat - is inclined. This procedure prevents an uncontrolled movement of the space closure element relative to the swivel arm, which could result in an uncontrolled rotation of the space closure element about the axis of rotation of the coupling means.

In a further advantageous embodiment of the method according to the invention, it can be particularly advantageous if the swivel arm is locked against the room closing element in such a way that the room closing element cannot be moved into its SHEV position without prior unlocking, preferably the locking of the swivel arm against the room closing element at the same time takes place with an unlocking of the space termination element from the curb. Locking the swivel arm against the space closure element initially offers the advantage that any further relative movement of the two components with respect to one another can be prevented. Due to the special movement characteristics that are required for the gravity-driven transfer of the space closure element into the SHEV position, the swivel arm and the space closure element can typically not be non-rotatably coupled to one another. Instead, it is advantageous if both components can rotate relative to one another at least during the first movement section, so that a lifting of the space closure element from the curb is made possible in principle, which in turn makes it possible to establish a distance between the space closure element and the curb. The two-part movement sequence of the space closure element in the course of the transfer from its closed position to its RWA position is achieved in particular as a result of the arrangement of a point of engagement of the drive on the swivel arm at a distance from the coupling means by means of which the space closure element and the swivel arm are coupled to one another.

In this way, the space closure element can be raised, in particular during a first movement section, until the swivel arm, which may initially be inclined in particular obliquely against a horizontal, at least essentially reaches a horizontal orientation and can then be brought together with the space closure element, which is meanwhile partially attached to the Curb was locked. At the moment of contact between the swivel arm and the space termination element (apart from the coupling means), the locking device can then be released and the locking of the space termination element against the curb can be released. The space closure element is preferably locked or coupled to the swivel arm at the same time and "taken along" by the latter in the course of the further movement of the swivel arm. In this second movement section, the space closure element is finally completely lifted off its sealing seat and is increasingly inclined towards the horizontal as the swivel arm continues to pivot. In this way, the room closure element can be transferred in a permanently controlled manner to its intermediate position, from which it is possible to slide into the SHEV position solely by gravity. All that needs to be done is to release the locking element so that the movement frame is released.

The embodiment that in the Figures 1 to 9 is shown, comprises a space termination device 1 according to the invention, which comprises a curb 2 and a space termination element 3 . The curb 2 is formed here by a four-sided body, which has four straight side walls 16 . The side walls 16 each define an edge 15 of the upstand 2. At an upper end face, the upstand 2 has a circumferential sealing surface which is arranged within a sealing plane 13 . The room closure element 3, which in the Figure 1 shown position is in its closed position, lies on the curb 2 such that it cooperates sealingly with the same. In this way, a fluidic connection between a room, which is separated from the environment by means of the room termination device 1 , and the environment is interrupted. In particular, the room termination element 3 closes airtight with the curb 2 .

In order to be able to transfer the room end element 3 from its closed position in the direction of an SHE position, in particular to enable ventilation of the room, the room end element 3 interacts with a drive 4 . The latter is formed here by an electrical drive unit, by means of which a compressive force can be exerted. The drive 4 interacts here directly with two transmission devices 5 , by means of which the force brought about by the drive 4 can be transmitted to the space closure element 3 . The transmission devices 5 are each formed by a swivel arm 7 and thus each in one piece, a respective swivel arm 7 being arranged on an edge 15 of the upstand 2 with the formation of a common swivel axis 8 . In the example, this is done by means of mounting brackets which are fastened to the curb 2 in a force-transmitting manner. The mounting brackets interact with the swivel arms 7 . The swivel arms 7 are arranged on both sides of the room closure element 3 . A point of attack of the drive 4 on a respective swivel arm 7 is at a distance from the swivel axis 8, so that the point of attack is arranged below a lever arm 10 relative to the swivel axis 8 . In this way, by means of the operation of the drive 4, it is possible to pivot the swivel arms 7 about the swivel axis 8 . In principle, it is conceivable to equip each of the swivel arms 7 with its own drive 4 ; in a particularly advantageous manner, however, a force made available by means of a drive 4 is distributed to both swivel arms 7 or only one of the swivel arms 7 is moved directly by means of the drive 4 . The each other swivel arm 7 is dragged along in the latter constellation via the space closure element 3 . The description made below relates only to one of the swivel arms 7, but basically relates to both swivel arms 7 in the embodiment .

The swivel arm 7 is connected to the space closure element 3 by means of a coupling means 9 in a manner that transmits force directly. The consequence of this is that a movement of the swivel arm 7 also directly causes a movement of the space closure element 3 . The coupling means 9 is designed here as a tab 17 , which cooperates with the space closure element 3 to form an axis of rotation 19 . In the example shown, the swivel arms 7 are each formed straight and each have a longitudinal axis 26 . The coupling means 9 of both swivel arms 7 each have an axis of rotation 19 , about which the space closure element 3 can be rotated relative to the swivel arm 7 . The coupling means 9 are positioned identically on both swivel arms 7 , so that the axes of rotation 19 of both coupling means 9 match. The "common axis of rotation" 19 is here advantageously arranged parallel to the pivot axis 8 of the space closure element 3 .

A distance 18, in which the coupling means 9 is arranged on the swivel arm 7 , corresponds in the example shown to approximately 50% of a total length of the swivel arm 7. This positioning has the consequence that the space closure element 3 is not solely due to its weight force about the axis of rotation 19 rotates, but can at least substantially maintain its rotational position in the course of the movement of the swivel arms 7 . Since the room closing element 3 is associated in the example shown, along one edge 27 to the curb 2, the room closing element 3 in the course of raising of the pivot arms 7 in a in is Figure 2 shown inclined coupling position moves. When this coupling position is reached, the swivel arm 7 is coupled with a coupling means 21 arranged at its end remote from the swivel axis 8 to a movement frame 11 of the space closure element 3 , so that the movement frame 11 and the swivel arm 7 are connected to one another at the location of the coupling means 21 . Until the coupling position is reached, the space closure element 3 can be rotated relative to the swivel arm 7 about the axis of rotation 19 .

When the coupling position is reached, the connection between the edge 27 of the space closure element 3 and the curb 2 is broken at least substantially at the same time. In this way, further operation of the drive 4 leads to a complete lifting of the space closure element 3 from its sealing seat, whereby a rotational position of the space closure element 3 relative to the swivel arms 7 is held securely by means of the coupling means 21 . A rotation of the two components relative to one another is then no longer possible. In this way, an uncontrolled movement of the space closure element 3 around the axes of rotation 19 is prevented. By means of the lifting off of the room closure element 3 , a circumferential flow cross section 6 is then released, which enables an air exchange between the room and the surroundings. In other words, the space closure element 3 is completely in a position distant from the sealing plane 13 and is consequently completely lifted out of its sealing seat. Such in Figure 3 Intermediate position of the space closure element 3 shown is suitable, for example, to ventilate the respective space.

The coupling means 21 arranged on the ends of the swivel arms 7 facing away from the swivel axis 8 are each formed here by a mechanical locking lock. The coupling means 21 is suitable for positively interacting with a complementary coupling means of the movement frame 11 of the space closure element 3 and in this way producing a force-transmitting, non-destructive releasable coupling.

The design of the room closure element 3 with a movement frame 11 is particularly advantageous. The latter is in direct engagement with the swivel arms 7. The coupling means of the space closure element 3, which cooperates with the coupling means 21 of a respective swivel arm 7 , is formed on the movement frame 11 . In the example shown, this movement frame 11 is equipped with two telescopic rails, one of the telescopic rails interacting with one of the swivel arms 7 . The fixation of the movement frame 11 on the swivel arms 7 by means of two coupling means 9, 21 serves to enable a torque-transmitting mounting of the space closure element 3 on the swivel arms 7 , which prevents an uncontrolled rotation of the space closure element 3 relative to the swivel arms 7 . The necessity for this arises from the Figures 4 and 5 , These illustrate the space closure element 3 first when the swivel arms 7 are present in their preposition and finally in their deflection position, from which the space closure element 3 can be transferred into its SHEV position. The latter is in Figure 5 shown. Coupling in a torque-transmitting manner is necessary, since the space closure element 3 would otherwise rotate about its axis of rotation 19 relative to the pivot arms 7 on the pivot axis 8 . In the example shown, this would prevent the room termination element 3 from being moved into its RWA position.

In said SHEV position, the maximum flow cross-section 6 between the surroundings and the room is released, so that, in particular, an emergency ventilation of the room can take place. This "maximum release" of the flow cross-section 6 consists here in that a cross-section of the curb 2 in the area of the sealing plane 13 is completely released and is thus completely available as a flow cross-section 6 . Ventilation of the room is consequently just as possible in this state as if the room closure element 3 were not present. This type of emergency ventilation is primarily important in the event of a fire.

In order to transfer the room closure element 3 into its SHEV position, the swivel arms 7 are moved by means of the drive 4 starting from the in Figure 3 Intermediate position shown further pivoted about the pivot axis 8 , so that the pivot arms 7 are transferred together with the space closure element 3 in an increasingly oblique position. In this inclined position of the swivel arms 7 , the space closure element 3 is oriented at an angle with respect to the sealing plane 13 . The swivel arms 7 are deflected until the said angle assumes the value of a critical angle 24 . This is in Figure 5 illustrated. When this limit angle 24 is reached, the swivel arms 7 are in their deflected position, the space closure element 3 being arranged obliquely in such a way that a flat part 12 of the same can move translationally relative to the swivel arms 7 solely because of its weight. Such a movement is made possible by means of the movement frame 11 , which has the telescopic rails described above.

For the final transfer of the space closure element 3 into its SHE position, a latching means 14 of the space closure element 3 is now released, whereby the surface part 12 is decoupled from the movement frame 11 and can move relative to the latter. As a result, the surface part 12 - driven solely by its weight - moves translationally relative to the swivel arms 7, so that it is "completely moved" out of an opening area of the curb 2 . The flow cross-section 6 between the room and the surroundings is thus completely released, so that an air flow, in particular out of the room, can take place in the vertical direction upwards into the surroundings without obstacles. The flow cross section 6 essentially corresponds to an opening cross section of the curb 2.

When considering the in Figure 6 shown SHE position of the space termination element 3 , the purpose of the two coupling means 9, 21 of a respective swivel arm 7 is immediately apparent . A storage of the space termination element 3 only by means of the first coupling means 9 would result in a rotation of the Space termination element 3 about the axis of rotation 19 result, since the center of gravity of the space termination element 3 is shifted far in the direction of the pivot axis 8 due to the movement of the surface part. Such a "tilting" of the space closure element 3 about the axis of rotation 19 could lead to the surface part 12 colliding with the edge 15 of the upstand 2 facing the pivot axis 8 in the course of its "slipping". A reliable opening of the room termination device 1 would thus be prevented.

The latching means 14 is advantageously coupled to the respective swivel arm 7 in such a way that it automatically releases the translational movement between the surface part 12 and the movement frame 11 as soon as the swivel arms 7 are swiveled about the swivel axis 8 to such an extent that the space closure element 3 forms the limit angle 24 is arranged relative to the sealing plane 13 . The swivel arms 7 are then in their respective deflected positions.

In contrast to the prior art, it follows that an entire stroke, by which a piston 22 of the drive 4 must be extended from the associated cylinder 23 , is particularly small in comparison to the prior art, since the space closure element 3 in particular is not at 90 ° or must be pivoted relative to the sealing plane 13 . The smaller pivoting angle means that the movement of the room closure element 3 can be significantly shorter overall, as a result of which the overall duration of the transfer of the room closure element 3 from its closed position to its SHEV position turns out to be significantly shorter than is possible in the prior art. At the same time, the drive 4 can be dimensioned considerably smaller than in the prior art, which also results in a cost advantage.

After the room closure element 3 has been transferred into its RWA position, it may be of interest to move it back into its closed position. In particular, for example, a fire alarm that initiated the movement of the room closure element 3 could have been a false alarm, after the end of which the original state of the room closure device 1 is to be restored. In the prior art, this is often not possible at all, since the transfer of the respective room closure element 3 into its SHEV position is not carried out without destruction.

In the example shown, however, the return of the room termination element 3 is particularly easy. This is particularly evident from the Figures 7 to 9 , First, the swivel arms 7 are swiveled back about the swivel axis 8 by means of the drive 4 until longitudinal axes 26 of the swivel arms 7 are arranged at an angle 25 relative to the horizontal sealing plane 13 . The swivel arms 7 are then in their Forward position. This results from Figure 7 , The angle 25 between the longitudinal axis 26 and the sealing plane 13 when the swivel arms 7 are present in this rear position is negative with respect to the sealing plane 13 , while the limit angle 24 described above is positive when the swivel arms 7 are present in their deflected position. The inclination of the swivel arms 7 present in their return position means that the weight of the flat part 12 receives a horizontal component in the direction of the curb 2 . This in turn leads to the fact that the surface part 12 is moved back from its emergency position into its normal position solely by the action of gravity by means of the movement frame 11 . The result of this process is particularly good based on Figure 8 recognizable.

By further lowering the swivel arms 7 , the space closure element 3 is then placed in its sealing seat again in the desired manner, so that the space closure element 3 seals against the curb 2 at least rainproof, preferably airtight. As a result, the room closure element 3 is ultimately in its closed position again Figure 9 results. In this case, the space termination element 3 is first placed on the curb 2 with its one edge 27 . The edge 27 is then coupled in a force-transmitting manner to the curb 2 and at the same time the coupling means 21 for connecting the swivel arms 7 and the moving frame 11 are released . In this way, the swivel arms 7 can again be swiveled relative to the movement frame 11 about the axis of rotation 9 . The room closure element 3 is at this moment in the Figure 2 orientation shown. Finally, by further retracting the drive 4, Figure 9 shown closed position reached.
