Description

Die Erfindung betrifft eine Verschließvorrichtung zum Verschließen von Öffnungen in Schutzräumen nach dem Oberbegriff des Hauptanspruchs.The invention relates to a closing device for closing openings in shelters according to the preamble of the main claim.

Es besteht das Bedürfnis, wichtige Dokumente, Datenträger, Chemikalien oder dergleichen so zu lagern, daß sie bei unerwünschter Einwirkung von außen, beispielsweise die erhöhte Wärmeeinwirkung bei einem Brand, nicht zerstört werden. Aus der DE-OS 30 10 031 ist ein Schutzraum für datenträgersichere Aufbewahrung von Datenträgern bekannt, dessen Wand aus mehreren Schichten aus wärmedämmendem Material besteht. Bei derartigen Schutzräumen müssen auch vorhandene Öffnungen wie Türen und Klimaöffnungen derart abgeschlossen sein, daß auch hier keine Übertragung der schädlichen Einwirkung, beispielsweise der Wärme im Brandfall, stattfindet.There is a need to store important documents, data carriers, chemicals or the like in such a way that they are not destroyed in the event of undesired external influences, for example the increased heat exposure in the event of a fire. From DE-OS 30 10 031 a protective space for data-secure storage of data carriers is known, the wall of which consists of several layers of heat-insulating material. With such shelters, existing openings such as doors and air-conditioning openings must also be closed in such a way that the harmful effects, such as heat in the event of fire, are not transmitted here either.

In der benannten Druckschrift ist zwar ein Verschließelement für die Klimaöffnung und eine Tür für die Durchgangsöffnung angedeutet, über den Aufbau wird aber nichts ausgeführt, es ist lediglich zu erkennen, daß zwei parallele Türelemente vorhanden sind.In the named publication, although a closing element for the air conditioning opening and a door for the through opening are indicated, nothing is said about the structure, it can only be seen that two parallel door elements are present.

Die europäische Patentanmeldung 0 169 802 beschreibt ein begehbares Schutzhaus mit Wänden und einer Decke aus mehreren Schichten hoher Wärmedämmung, die mechanisch fest und selbsttragend sind. Das Schutzhaus besitzt eine Tür mit einem der Wand entsprechenden Aufbau, die nach außen schwenkbar ist.European patent application 0 169 802 describes a walk-in shelter with walls and a ceiling made of several layers of high thermal insulation that are mechanically strong and self-supporting. The shelter has a door with a wall-mounted structure that can be pivoted outwards.

Aus der europäischen Patentanmeldung 0 0023621 ist ein feuerfester Stahlschrank, Tresor oder dergleichen bekannt, bei dem eine Doppelwandung vorgesehen ist, die mit einem chemischen Feststoff mit einem Schmelzpunkt von etwa 30 bis 40° C ausgefüllt ist. Bei erhöhten Temperatureinflüssen infolge eines Brandes oder dergleichen in der Umgebung des Stahlschrankes wird die auf den Schrank wirkende Wärmeenergie über einen längeren Zeitraum für die Überwindung des Schmelzpunktes des chemischen Feststoffes verbraucht. Dieser Schrank weist zwei Türen auf, die jeweils von außen betätigbar sind, wobei die innere Tür doppelwandig ausgebildet ist und mit dem chemischen Feststoff gefüllt ist. Die äußere Tür weist zwei Kammern auf, in denen sich einerseits Glaswolle und andererseits Beton befinden. Die Anschläge der Tür sind außen an der Wand angeordnet. Die gesamte Last der Türen wird somit von der Wand gehalten.From European patent application 0 0023621 a fireproof steel cabinet, safe or the like is known, in which a double wall is provided, which is filled with a chemical solid with a melting point of about 30 to 40 ° C. With increased temperature influences due to a fire or the like in the vicinity of the steel cabinet, the thermal energy acting on the cabinet is used over a longer period of time to overcome the melting point of the chemical solid. This cabinet has two doors, each of which can be operated from the outside, the inner door being double-walled and filled with the chemical solid. The outer door has two chambers, on the one hand glass wool and on the other hand concrete. The door stops are located on the outside of the wall. The entire load of the doors is thus held by the wall.

Im Brandfall treten außen sehr hohe Temperaturen auf, die auf die Wände einwirken, so daß Verwerfungen auftreten können. Dies wird durch die Last der Türen verstärkt, wobei durch die Deformation auch die Anschläge in Mitleidenschaft gezogen werden können, so daß die Tür nicht mehr dicht abschließt, was zu einer Erhöhung der Temperatur im Innenraum beiträgt,In the event of a fire, very high temperatures occur on the outside, which can cause warping. This is exacerbated by the load on the doors, and the stops can also be affected by the deformation, so that the door no longer closes tightly, which contributes to an increase in the temperature in the interior,

Der Erfindung liegt die Aufgabe zugrunde, eine Verschließvorrichtung zum Verschließen von Öffnungen in Schutzräumen zu schaffen, die auch bei von außen her einwirkenden hohen Temperaturen und bei mechanischen Belastungen von außen her die Dichtigkeit zum Abschirmen des Innenraumes gegen die äußeren Einwirkungen beibehält und die sowohl von innen als auch von außen zu öffnen und zu schließen ist.The invention has for its object to provide a closing device for closing openings in shelters, which maintains the tightness for shielding the interior against external influences even at high temperatures and mechanical loads from the outside and which both from the inside as well as opening and closing from the outside.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Hauptanspruchs in Verbindung mit den Merkmalen des Oberbegriffs gelöst.This object is achieved by the characterizing features of the main claim in conjunction with the features of the preamble.

Durch Vorsehen einer von der Wand lastmäßig unabhängigen Tragkonstruktion, die im Innenraum des Schutzraumes vor der Wand angeordnet ist, wobei die Öffnung mit nur einem vom Innenraum gesehen nach außen herausschwenkbaren Wandelement abgeschlossen ist, das an Tragarmen an der Tragkonstruktion gehalten ist, wird die Wand nicht mehr vom Gewicht des Wandelementes belastet, und die Anschläge bzw. die Tragkonstruktion mit den Tragarmen befinden sich im kalten Bereich, so daß keine Verformungen oder dergleichen auftreten können, die die Dichtheit beeinflussen können. Wegen der Anordnung der Tragkonstruktion ist nur ein einziges herausschwenkbares Wandelement notwendig, das sehr viel einfacher zu öffnen und zu schließen ist und besonders im Brandfall ein gesteuertes automatisches Schließen ermöglicht.By providing a load-bearing structure which is independent of the wall and which is arranged in the interior of the protective space in front of the wall, the opening being closed off with only one wall element which can be pivoted outwards as seen from the interior and is held on support arms on the support structure, the wall is not more burdened by the weight of the wall element, and the stops or the support structure with the support arms are in the cold area, so that no deformations or the like can occur that can affect the tightness. Because of the arrangement of the supporting structure, only a single pivoting wall element is necessary, which is much easier to open and close and which enables controlled automatic closing, particularly in the event of a fire.

Erfindungsgemäß ist die Verriegelung des Wandelementes an seiner Innenseite angeordnet, wobei die die Verriegelung betätigende Betätigungsvorrichtung sowohl von innen als auch von außen zugänglich ist. Die Verriegelung kann somit im kalten Bereich angeordnet sein. Durch die erfindungsgemäße Ausbildung ist somit keine Doppeltür notwendig, so daß die Handhabung sehr viel einfacher ist.According to the invention, the locking of the wall element is arranged on its inside, the actuating device actuating the locking being accessible both from the inside and from the outside. The lock can thus be arranged in the cold area. Due to the design according to the invention, a double door is therefore not necessary, so that handling is much easier.

In einer vorteilhaften Ausführungsform ist der Tragarm nicht nur an einem Holm der Tragkonstruktion, sondern auch an einem mit der Tür verbundenen Verbindungsstück drehbar gelagert, so daß für das Herausschwenken des Wandelementes mehrere Freiheitsgrade zur Verfügung stehen. Zum gesteuerten Herausschwenken ist zusätzlich ein Steuerhebel vorgesehen, der ebenfalls an dem Holm und an dem Verbindungsstück drehbar angelenkt ist. Vorteilhafterweise sind die Anlenkpunkte des Steuerhebels und des Tragarmes an dem Holm und an dem Verbindungsstück angeordnet, derart, daß die Schwenkbahnen der Anlenkpunkte am Verbindungsstück um die Anlenkpunkte am Holm herum sich kreuzen. Dadurch ist ein gesteuertes Öffnen bzw. Schließen in der Weise möglich, daß beim Öffnen das Wandelement erst parallel zur Wand aus der Öffnung herausgeschoben wird und erst dann ein Schwenken des Wandelementes erfolgt. Ein derartiger Bewegungsablauf vermeidet auch bei einer dicken Tür eine Behinderung durch die Wand.In an advantageous embodiment, the support arm is rotatably supported not only on a spar of the support structure, but also on a connecting piece connected to the door, so that several degrees of freedom are available for pivoting out the wall element. For controlled swiveling out, a control lever is additionally provided, which is also pivoted on the spar and on the connecting piece. Advantageously, the articulation points of the control lever and the support arm are arranged on the spar and on the connecting piece in such a way that the swivel paths of the articulation points on the connecting piece intersect around the articulation points on the spar. This enables controlled opening or closing in such a way that when opening the wall element is first pushed out of the opening parallel to the wall and only then is the wall element pivoted. Such a sequence of movements avoids obstruction by the wall even with a thick door.

Die sichere brandschutzmäßige Trennung der Betätigungsvorrichtung wird dadurch realisiert, daß sie eine durch die Wandung des Wandelements hindurchgehende Welle aufweist, die innerhalb der Wandung unter Bildung von zwei Teilwellen unterbrochen ist, die durch ein im Brandfall sich auflösendes Verbindungselement verbunden sind. Damit kann die Verriegelung über eine im normalen Betriebszustand durchgehende Welle betätigt werden, die bei Wärmeeinwirkung unterbrochen wird, so daß keine Wärmeleitung stattfinden kann. Vorteilhafterweise wird um die Betätigungsvorrichtung herum im Brandfall ein bei hohen Temperaturen aufschäumbares Material vorgesehen. Das aufschäumbare Material ist derart ausgewählt, daß es beim Aufschäumen Wasserdampf freigibt, das zusätzlich zur Kühlung der Teilwellen dient. Wenn das Material im nach außen gerichteten Bereich angeordnet ist, wird es insbesondere während der ersten bis zweiten Stunde des Brandes wirksam. Bei Vorsehen des Materials zwischen den Teilwellen tritt eine Kühlung zwischen zwei und vierundzwanzig Stunden nach Beginn des Brandes in Kraft.The safe fire protection separation of the actuation device is realized by that it has a shaft passing through the wall of the wall element, which is interrupted within the wall to form two partial waves, which are connected by a connecting element that dissolves in the event of a fire. The lock can thus be actuated via a shaft which is continuous in the normal operating state and which is interrupted when exposed to heat, so that no heat conduction can take place. In the event of fire, a material that can be foamed at high temperatures is advantageously provided around the actuating device. The foamable material is selected such that it releases water vapor when foaming, which is also used to cool the partial waves. If the material is located in the outward-facing area, it becomes effective particularly during the first to second hour of the fire. If the material is provided between the partial waves, cooling takes effect between two and twenty-four hours after the start of the fire.

In einem bevorzugten Ausführungsbeispiel weist die Betätigungsvorrichtung vorteilhafterweise einen Elektromagneten mit Magnetplatte auf, über den die Riegelbolzen der Verriegelung nach ihrer vollständigen Entriegelung im zurückgezogenen Zustand gehalten werden. Dadurch stören die Riegelbolzen nicht die Bewegung der Tür, d.h., sie schleifen nicht an der Türfüllung, so daß das amorphe Brandschutzmaterial nicht beschädigt wird.In a preferred exemplary embodiment, the actuating device advantageously has an electromagnet with a magnetic plate, via which the locking bolts of the locking device are held in the retracted state after their complete unlocking. As a result, the locking bolts do not interfere with the movement of the door, ie they do not rub against the door panel, so that the amorphous fire protection material is not damaged.

Vorteilhafterweise ist das Wandelement mit einer vorzugsweise im kalten Bereich angeordneten, einen Elektromotor aufweisenden Antriebseinheit versehen, die das Wandelement nach Entriegelung der Riegelbolzen automatisch öffnet bzw. schließt. Auf diese Weise ist es neben der Vereinfachung der Handhabung des Wandelementes im normalen Betriebszustand möglich, daß das Wandelement bei Auftreten eines Brandes automatisch geschlossen werden kann, wobei das Steuersignal für das Schließen von einem mit der Antriebseinheit verbundenen Rauch- oder Temperatursensor oder dergleichen abgegeben wird.Advantageously, the wall element is provided with a drive unit, preferably arranged in the cold area and having an electric motor, which automatically opens or closes the wall element after unlocking the locking bolts. In this way, in addition to simplifying the handling of the wall element in the normal operating state, it is possible for the wall element to be closed automatically in the event of a fire, the control signal for the closure being emitted by a smoke or temperature sensor or the like connected to the drive unit.

Vorzugsweise weist die Antriebseinheit zwei miteinander verbundene Hebel auf, von denen der eine an dem Wandelement befestigt und der andere mit dem Elektromotor der Antriebseinheit in Wirkverbindung steht, derart, daß der Winkel zwischen den Hebeln bei Bewegung des Wandelementes in den geschlossenen Zustand gegen Null geht. Dadurch hat aufgrund der Sinusbewegung der Motor im annähernd geschlossenen Zustand des Wandelementes die größte Kraft und zieht dadurch das Wandelement richtig in die Leibung herein, wobei gleichzeitig die Metallplatte vom Elektromagneten losgelassen wird und die Riegelbolzen herausfahren.Preferably, the drive unit has two interconnected levers, one of which is attached to the wall element and the other of which is operatively connected to the electric motor of the drive unit, such that the angle between the levers approaches zero when the wall element moves in the closed state. As a result, the motor has the greatest force when the wall element is in an approximately closed state due to the sinusoidal movement and thereby pulls the wall element correctly into the reveal, at the same time the metal plate is released from the electromagnet and the locking bolts move out.

In einer vorteilhaften Ausführungsform der Erfindung weist die Antriebseinheit ein durch den Elektromotor angetriebenes Ritzel und eine auf einer Welle sitzende, mit dem Ritzel in Eingriff tretende Zahnscheibe auf, wobei die Bewegung der Welle die Bewegung des Wandelementes hervorruft. Damit das Wandelement aber auch im Notfalle von Hand vom Innenraum her geöffnet werden kann, ist das Ritzel zum Lösen des Eingriffs mit der Zahnscheibe verschiebbar angeordnet, wobei die Verschiebung über ein Gestänge durchführbar ist.In an advantageous embodiment of the invention, the drive unit has a pinion driven by the electric motor and a toothed disk which is seated on a shaft and engages with the pinion, the movement of the Wave causes the movement of the wall element. So that the wall element can also be opened by hand from the interior in an emergency, the pinion for releasing the engagement with the toothed disk is arranged displaceably, the displacement being able to be carried out via a linkage.

Damit beim automatischen Schließen der Tür durch die Antriebseinheit keine Personen eingeklemmt werden, ist eine Rutschkupplung vorgesehen.A slipping clutch is provided so that no people are trapped by the drive unit when the door closes automatically.

Üblicherweise wird die Betätigung der Betätigungseinrichtung zum Öffnen bzw. Schließen der Verriegelung über zwei Handräder vorgenommen, die jeweils an den Enden der Welle der Betätigungsvorrichtung angeordnet sind. Falls das Wandelement nur von dafür befugten Personen geöffnet werden soll, kann anstelle der Handräder ein Elektromotor vorgesehen sein, der die Welle der Betätigungseinrichtung dreht, wobei der Elektromotor beispielsweise durch eine Kodiereinrichtung angesteuert werden kann.The actuation of the actuating device for opening or closing the locking is usually carried out via two handwheels, which are each arranged at the ends of the shaft of the actuating device. If the wall element is only to be opened by authorized persons, an electric motor can be provided instead of the handwheels, which rotates the shaft of the actuating device, the electric motor being able to be controlled, for example, by a coding device.

In Fig. 1 ist der Schnitt durch einen Schutzraum 1 dargestellt, der in einem Gebäude üblicherweise auf einem Betonboden 2 angeordnet ist. Dieser Schutzraum 1 dient zur sicheren Aufbewahrung, insbesondere im Falle eines Brandes, von Datenträgern, Chemikalien, wichtigen Dokumenten oder dergleichen, und ist durch eine von einer Verschließvorrichtung 3 verschließbaren Durchgang 4 begehbar. Die Wände 5 des Schutzraumes 1 bestehen aus einer inneren und einer äußeren Metallhülle, zwischen denen Wärmedämmaterial, wie Brandschutzplatten, eingesetzt sind, wobei zusätzlich ein Stützenwerk im Inneren der Wände vorgesehen ist und die Schichten selbsttragend und mechanisch nicht miteinander verbunden sind.In Fig. 1 the section through a shelter 1 is shown, which is usually arranged in a building on a concrete floor 2. This protective room 1 serves for safe storage, in particular in the event of a fire, from data carriers, chemicals, important documents or the like, and can be accessed through a passage 4 which can be closed by a closing device 3. The walls 5 of the protective space 1 consist of an inner and an outer metal shell, between which thermal insulation material, such as fire protection panels, are inserted, a support structure being additionally provided inside the walls and the layers not being self-supporting and mechanically connected to one another.

Die Verschließvorrichtung 3 weist ein herausschwenkbares Wandelement 5 auf, dessen konstruktiver Aufbau dem der Wände entspricht, d.h., es besteht ebenfalls aus einer inneren und äußeren Metallhülle, zwischen denen Schichten aus Wärmedämmaterial angeordnet sind. Zur guten Abdichtung zwischen Innenraum 6 des Schutzraumes 1 und Außenraum 7 sind das Wandelement 5 und die die Öffnung 8 in der Wand 9 begrenzende Leibung 10 mehrfach gefalzt.The closing device 3 has a pivotable wall element 5, the construction of which corresponds to that of the walls, i.e. it also consists of an inner and outer metal shell, between which layers of thermal insulation material are arranged. For a good seal between the interior 6 of the shelter 1 and the exterior 7, the wall element 5 and the reveal 10 delimiting the opening 8 in the wall 9 are folded several times.

Gemäß den Fig. 1 und 2 ist im Innenraum 6 eine Tragkonstruktion 11 für das herausschwenkbare Wandelement 5 vorgesehen, die im vorliegenden Ausführungsbeispiel einen Rahmen 12 aus Vierkantrohren und eine mit diesem verbundene Bodenplatte 13 aufweist. Die Tragkonstruktion 11 steht vor der Wand 9 und ist lastmäßig unabhängig von dieser, wobei die Last über die Bodenplatte 13 und eine Unterkonstruktion 14 vom Betonboden 2 aufgenommen wird. Allerdings kann sich der Rahmen 12 über Abstützelemente 15 an der Wand 9 abstützen.1 and 2, a support structure 11 is provided in the interior 6 for the pivotable wall element 5, which in the present exemplary embodiment has a frame 12 made of square tubes and a base plate 13 connected to it. The support structure 11 stands in front of the wall 9 and is independent of the load, the load being absorbed by the concrete floor 2 via the base plate 13 and a substructure 14. However, the frame 12 can be supported on the wall 9 via support elements 15.

Wie insbesondere aus Fig. 2 zu erkennen ist, steht der Holm 16 des Rahmens 12, an dem das Wandelement 5 befestigt ist, vor der Öffnung 4, so daß die Breite der Öffnung 4 größer sein muß als die Breite des wirklichen Durchganges 8, der einerseits vom Holm 16 und andererseits vom die Öffnung 4 umschließenden Wandteil 17 begrenzt wird. An dem Holm 16 sind zwei Tragarme 18 drehbar angelenkt, deren gegenüberliegende Enden ein Verbindungsstück 19 aufnehmen, das um das Ende des Tragarmes 18 herum schwenkbar ist und das fest mit dem Wandelement 5 verbunden ist. Benachbart zu den Tragarmen 18 sind Steuerhebel 20 angeordnet, die ebenfalls mit ihren einen Enden am Holm 16 und mit ihren anderen Enden am Verbindungsstück 19 angelenkt sind. Beim Herausfahren des Wandelementes verhindern die Steuerhebel 20 am Anfang der Bewegung ein Schwenken des Wandelementes 5 und sorgen für eine Bewegung des Wandelementes 5 parallel zur Öffnung 4 bis die Schwenkbewegung freigegeben wird, die wegen der Dicke des Wandelementes und der Wand am Anfang nicht möglich ist. Im geöffneten Zustand des Wandelementes stehen die Tragarme 18 in etwa senkrecht zu der Öffnung, d.h. sie stehen in einem Winkel von etwa 90°, wenn eine imaginäre Linie von den jeweiligen Anlenkpunkten 21, 22 am Holm 16 parallel zur Breite des Durchganges 8 den Winkel von 0° definiert. In dieser Stellung der Tragarme 18 ist der Winkel zwischen der imaginären Linie und den Steuerhebeln 20 größer als 90°. Zum Schließen des Wandelementes 5 werden die Tragarme 18 und die Steuerhebel 20 um einen Schwenkweg geschwenkt, der in dem Winkelbereich zwischen 90° und 180° liegt. Dabei schneiden sich die Schwenkbahnen der Anlenkpunkte 23, 24 der Enden der Steuerhebel und der Tragarme an das Verbindungsstück 19 um den jeweiligen Anlenkpunkt 21, 22 am Holm 16. Die Anlenkpunkte 21, 23 der Steuerhebel 20 sind in Richtung zum Durchgang 8 zu den Anlenkpunkten 22, 24 der Tragarme 18 im geschlossenen Zustand des Wandelementes 5 seitlich versetzt. Vorzugsweise sind dabei die Steuerhebel 20 länger als die Tragarme 18.As can be seen in particular from Fig. 2, the spar 16 of the frame 12, to which the wall element 5 is attached, is in front of the opening 4, so that the width of the opening 4 must be greater than the width of the actual passage 8, the is limited on the one hand by the spar 16 and on the other hand by the wall part 17 surrounding the opening 4. Two support arms 18 are rotatably articulated on the spar 16, the opposite ends of which receive a connecting piece 19 which can be pivoted around the end of the support arm 18 and which is firmly connected to the wall element 5. Control levers 20 are arranged adjacent to the support arms 18 and are likewise articulated at one end to the spar 16 and at the other ends to the connecting piece 19. When moving out the wall element, the control levers 20 prevent pivoting of the wall element 5 at the beginning of the movement and ensure a movement of the wall element 5 parallel to the opening 4 until the pivoting movement is released, which is not possible at the beginning because of the thickness of the wall element and the wall. In the open state of the wall element, the support arms 18 are approximately perpendicular to the opening, ie they are at an angle of approximately 90 °, if an imaginary line from the respective articulation points 21, 22 on the bar 16 parallel to the width of the passage 8, the angle of 0 ° defined. In this position of the support arms 18, the angle between the imaginary line and the control levers 20 is greater than 90 °. To close the wall element 5, the support arms 18 and the control levers 20 are pivoted by a pivot path which lies in the angular range between 90 ° and 180 °. The swivel paths of the articulation points 23, 24 of the ends of the control levers and the support arms on the connecting piece 19 intersect at the respective articulation point 21, 22 on the spar 16. The articulation points 21, 23 of the control levers 20 are in the direction of the passage 8 to the articulation points 22 , 24 of the support arms 18 laterally offset in the closed state of the wall element 5. The control levers 20 are preferably longer than the support arms 18.

Wenn das Wandelement 5 geschlossen ist, sind die Anlenkpunkte 22, 24 der Tragarme 18 zu den entsprechenden Anlenkpunkten 21, 23 der Steuerhebel 20 zum Innenraum 6 hin versetzt.When the wall element 5 is closed, the articulation points 22, 24 of the support arms 18 are offset to the corresponding articulation points 21, 23 of the control lever 20 towards the interior 6.

Wie schon oben erwähnt, ist die Öffnung 4 in der Wand 9 breiter als der Durchgang 8, so daß neben dem Holm 16 ein kleiner Öffnungsbereich 25 verbleibt, der nach außen hin ebenso wie die Tragarme und die Steuerhebel im geschlossenen Zustand des Wandelementes 5 von diesem abgedeckt wird. Vorzugsweise ist dieser offene Bereich 25 vom Innenraum her mit einer Verkleidung oder dergleichen abgedeckt. Die Verschließvorrichtung ist im Ausführungsbeispiel zum Verschließen von begehbaren Durchgängen beschrieben. In gleicher Weise können aber Verschließvorrichtungen für Klimaöffnungen oder dergleichen ausgebildet sein.As already mentioned above, the opening 4 in the wall 9 is wider than the passage 8, so that a small opening area 25 remains next to the spar 16, which to the outside as well as the support arms and the control levers in the closed state of the wall element 5 thereof is covered. This open area 25 is preferably covered from the inside with a covering or the like. The closing device is described in the exemplary embodiment for closing walkable passages. In the same way, however, closing devices for air-conditioning openings or the like can be designed.

Wie insbesondere aus Fig. 4 rechts zu erkennen ist, weist das Wandelement 5 ebenso wie die Leibung 102 einen aus Vierkantrohren 103 gebildeten, dem Innenraum zugewandten Rahmen auf. An dem Umfang des Wandelementes 5 sind gemäß Fig. 3 eine Mehrzahl von die Verriegelung 104 bildenden Riegelbolzen 105 angeordnet, die jeweils im verriegelten Zustand den Rahmen 103 der Leibung zumindest teilweise übergreifen. Die Riegelbolzen 105 sind von einem Drehpunkt 106 zu betätigen, wobei die Drehbewegung über Stangen 107, Kugelkopfgelenke 108 und drehbar gelagerte Winkelstücke 109 auf die Riegelbolzen 105 übertragen werden. Die Stangen 107 sind dabei auf einer den Drehpunkt 106 bildenden Scheibe 110 verbunden.As can be seen in particular from FIG. 4 on the right, the wall element 5, like the reveal 102, has a frame which is formed from square tubes 103 and faces the interior. According to FIG. 3, a plurality of locking bolts 105 forming the locking element 104 are arranged on the circumference of the wall element 5, each of which at least partially overlaps the frame 103 of the reveal in the locked state. The locking bolts 105 can be actuated from a pivot point 106, the rotational movement being transmitted to the locking bolts 105 via rods 107, ball-head joints 108 and rotatably mounted angle pieces 109. The rods 107 are on one that forms the pivot point 106 Disc 110 connected.

In Fig. 4 ist die Betätigungsvorrichtung 111 der Verriegelung im Schnitt dargestellt, die sowohl vom Innenraum 6 als auch vom Außenraum 7 über Handräder 114 betätigbar ist. Die Handräder 114 sitzen auf einer durch die Wandung 115 des Wandelementes 5 hindurchgehende Welle 16, die eine brandschutzmäßige Trennung 117 aufweist. Die Welle 116 besteht aus zwei Teilwellen 118, 199, deren Ende sich mit Abstand unter Bildung eines freien Raumes 120 zwischen ihnen gegenüberliegen. Auf den Wellenenden sitzt mit Preßpassung unter Überbrückung des freien Raumes 120 eine Hülse 121 aus Kunststoff, die zusätzlich über Stifte 122 mit den Wellenenden verbunden ist. Die Hülse 121 überträgt die Drehung der Teilwelle 118 auf die Teilwelle 119 und umgekehrt. Um den freien Raum 120 und die Enden der Teilwellen 118, 199 herum ist ein rohrförmiges Gitter oder Lochblech 123 angeordnet, das von einem zweiten, einen größeren Durchmesser aufweisenden Gitter 124 umgeben ist, so daß zwischen den Lochblechen ein Raum gebildet wird, der mit einem aufschäumbaren Material 125 gefüllt ist. Das aufschäumbare Material besteht beispielsweise aus Kalziumsilikat oder Natriumsilikat gemischt mit Wasserglas. Im Brandfall schmilzt aufgrund der Wärmeübertragung vom Außenraum her über die Teilwelle 118 die Hülse 121 weg und bei zirka 190° C beginnt das aufschäumbare Material 125 aufzuschäumen und füllt langsam den freien Raum 120, aus, wobei Wasserdampf abgegeben wird, der zusätzlich die Wellenenden kühlt. Dadurch wird eine Wärmeübertragung von der Teilwelle 118 auf die Teilwelle 119 weitgehend vermieden.In Fig. 4, the actuating device 111 of the lock is shown in section, which can be actuated both from the interior 6 and from the exterior 7 via handwheels 114. The handwheels 114 are seated on a shaft 16 which passes through the wall 115 of the wall element 5 and has a fire protection separation 117. The shaft 116 consists of two partial shafts 118, 199, the ends of which lie opposite one another at a distance, forming a free space 120 between them. A sleeve 121 made of plastic is seated on the shaft ends with a press fit while bridging the free space 120 and is additionally connected to the shaft ends via pins 122. The sleeve 121 transmits the rotation of the partial shaft 118 to the partial shaft 119 and vice versa. Around the free space 120 and the ends of the partial shafts 118, 199 a tubular grid or perforated plate 123 is arranged, which is surrounded by a second, larger diameter grid 124, so that a space is formed between the perforated plates, which with a foamable material 125 is filled. The foamable material consists for example of calcium silicate or sodium silicate mixed with water glass. In the event of a fire, the sleeve 121 melts away due to the heat transfer from the outside via the partial shaft 118 and at about 190 ° C. the foamable material 125 begins to foam and slowly fills up the free space 120, with water vapor being released additionally cools the shaft ends. As a result, heat transfer from the partial shaft 118 to the partial shaft 119 is largely avoided.

Bei einem Brand tritt nach einer Stunde ein Temperaturmaximum (1000° C) auf, wobei die Temperaturen langsam während eines Zeitraums von 23 Stunden abklingen und einen relativen konstanten Wert erreichen. Während dieses Zeitraumes darf die Temperatur im Innenraum höchstens um 30° C ansteigen. Wenn das aufschäumbare Material, wie beschrieben, im Inneren des Wandelementes angeordnet ist, wird die Kühlung der Betätigungsvorrichtung erst im Zeitraum zwischen der zweiten bis dreiundzwanzigsten Stunde nach dem Beginn des Brandes wirksam. Das aufschäumbare Material kann aber auch im nach außen gerichteten Bereich des Wandelementes um die Betätigungsvorrichtung, d.h. die Welle angeordnet sein. In diesem Fall tritt eine Kühlung während der ersten Stunde nach dem Beginn des Brandes auf.In the event of a fire, a temperature maximum (1000 ° C) occurs after one hour, the temperatures slowly decaying over a period of 23 hours and reaching a relatively constant value. During this period, the temperature in the interior may not increase by more than 30 ° C. If the foamable material, as described, is arranged inside the wall element, the cooling of the actuating device takes effect only in the period between the second to the twenty-third hour after the start of the fire. The foamable material can also in the outward-facing area of the wall element around the actuating device, i.e. the shaft must be arranged. In this case, cooling occurs during the first hour after the start of the fire.

Durch diese beschriebene Konstruktion ist es möglich, eine Betätigungsvorrichtung zu schaffen, die durch die Wandung des Wandelementes 5 hindurchgeht und von beiden Seiten betätigt werden kann, wobei trotzdem im Brandfalle eine Trennung vorgenommen wird und der Innenraum nicht über die Welle 116 aufgeheizt wird.By means of the construction described, it is possible to provide an actuating device which passes through the wall of the wall element 5 and can be actuated from both sides, a separation still being made in the event of a fire and the interior not being heated via the shaft 116.

Falls die Betätigungsvorrichtung 111 von außen mit einem Schloß 150 abschließbar ist, müssen Vorkehrungen getroffen werden, damit das Wandelement 5 für den Fall, daß jemand unbeabsichtigt eingeschlossen wird, von innen geöffnet werden kann. Dazu ist die Hülse 121 an der der Teilwelle 119 zugewandten Seite mit einer nicht dargestellten Quernut versehen, deren Länge dem Drehweg für die Entriegelung der Riegelbolzen 105 entspricht.If the actuating device 111 can be locked from the outside with a lock 150, precautions must be taken so that the wall element 5 in the event that someone unintentionally can be opened from the inside. For this purpose, the sleeve 121 is provided on the side facing the partial shaft 119 with a transverse groove (not shown), the length of which corresponds to the rotational path for unlocking the locking bolts 105.

Die Drehung der Welle 116 wird auf die Scheibe 110 übertragen und die Riegelbolzen 105 werden über das Gestänge 107,108,109 betätigt. Die Entriegelung erfolgt gegen den Druck einer auf den Riegelbolzen sitzenden, in Fig. 4 rechts zu erkennenden Feder 126. Auf der Scheibe 110 ist eine Metallplatte 127 über einen Arm 128 befestigt, die mit einem auf der Innenseite der Tür angeordneten Elektromagneten 129 zusammenarbeitet und einen Elektroschalter bildet. Wenn die Riegelbolzen aufgrund der Drehung der Welle 116 und entsprechend der Scheibe 110 in ihrem vollständig zurückgezogenen Zustand sind, berührt die Metallplatte 127 den Elektromagneten 129 und wird an diesem festgehalten. Somit bleiben die Riegelbolzen 105 im zurückgezogenen, entriegelten Zustand, so daß die Riegelbolzen 105 beim Öffnen des Wandelementes nicht an der Leibung schleifen können. Dadurch wird einerseits die Bewegung des Wandelementes 5 nicht behindert und andererseits wird das amorphe Brandschutzmaterial nicht durch eine Schleifbewegung beschädigt. Die Riegelbolzen bleiben somit während der gesamten Zeit entriegelt, in der das Wandelement 5 geöffnet ist. Beim Schließen des Wandelementes 5 wird seine Endstellung durch nicht dargestellte Endschalter abgetastet, die ein Signal an den Elektromagneten 129 abgeben, worauf dieser entregt wird und die Metallplatte 127 losläßt. Dadurch werden die Riegelbolzen 105 freigegeben und die Federn 126 drücken die Riegelbolzen 105 in ihre Verriegelungsstellung, wodurch das Wandelement 5 zusätzlich festgezogen wird.The rotation of the shaft 116 is transmitted to the disk 110 and the locking bolts 105 are actuated via the linkage 107, 108, 109. Unlocking takes place against the pressure of a spring 126 seated on the locking bolt, which can be seen on the right in FIG. 4. A metal plate 127 is fastened on the disc 110 via an arm 128, which cooperates with an electromagnet 129 arranged on the inside of the door and one Electric switch forms. When the locking bolts are in their fully retracted state due to the rotation of the shaft 116 and corresponding to the disc 110, the metal plate 127 contacts the electromagnet 129 and is held thereon. Thus, the locking bolts 105 remain in the retracted, unlocked state, so that the locking bolts 105 cannot grind against the reveal when the wall element is opened. As a result, on the one hand the movement of the wall element 5 is not hindered and on the other hand the amorphous fire protection material is not damaged by a grinding movement. The locking bolts thus remain unlocked during the entire time that the wall element 5 is open. When the wall element 5 is closed, its end position is scanned by limit switches, not shown, which send a signal to the electromagnet 129 deliver, whereupon this is de-energized and releases the metal plate 127. As a result, the locking bolts 105 are released and the springs 126 press the locking bolts 105 into their locking position, as a result of which the wall element 5 is additionally tightened.

Anstelle der Handräder 114 oder zusätzlich zu den Handrädern 114 können Elektromotoren vorgesehen sein, die die Welle 116 zum Entriegeln der Riegelbolzen 105 antreiben.Instead of the handwheels 114 or in addition to the handwheels 114, electric motors can be provided which drive the shaft 116 to unlock the locking bolts 105.

Um das Wandelement 5 auch automatisch öffnen und schließen zu können, ist eine Antriebseinheit 130 vorgesehen (Fig. 5), die im Innenraum 6, d.h. im kalten Bereich, oberhalb des Wandelementes 5 angeordnet ist. Die Antriebseinheit 130 besitzt eine eigene elektrische Versorgung, so daß sie auch dann noch funktionsfähig ist, wenn die elektrische Versorgung im Außenraum ausgefallen ist. Die Antriebseinheit sitzt auf einem Lagerbock 131 und weise einen Elektromotor 132 auf, der ein Ritzel 133 antreibt, wobei Elektromotor 132 und Ritzel 133 zusammen auf einem verschiebbaren Schlitten 134 sitzen. Das Ritzel greift in eine Zahnscheibe 135 ein, die auf einer Welle 136 gelagert ist, wobei eine Rutschkupplung 137 zwischengeschaltet ist. Am Ende der Welle 136 ist ein erster Hebel 38 befestigt, der über ein Gelenk 139 mit einem zweiten Hebel 140 verbunden ist. Der zweite Hebel 140 ist über ein weiteres Gelenk 141 an dem Wandelement 5 befestigt.In order to also be able to automatically open and close the wall element 5, a drive unit 130 is provided (FIG. 5), which is located in the interior 6, i.e. is arranged in the cold area, above the wall element 5. The drive unit 130 has its own electrical supply, so that it is still functional even if the electrical supply in the exterior has failed. The drive unit sits on a bearing block 131 and has an electric motor 132 which drives a pinion 133, the electric motor 132 and pinion 133 being seated together on a displaceable carriage 134. The pinion engages in a toothed disk 135, which is mounted on a shaft 136, with a slip clutch 137 being interposed. A first lever 38 is attached to the end of the shaft 136 and is connected to a second lever 140 via a joint 139. The second lever 140 is fastened to the wall element 5 via a further joint 141.

Zum Öffnen des Wandelementes 5 erhält die Antriebseinheit 130 von dem als Schalter ausgebildeten Elektromagneten 129 mit Metallplatte 127 bei Kontakt derselben ein Signal und der Elektromotor 132 treibt daraufhin das Ritzel 133 und über die Zahnscheibe 135 und die Welle 136 den ersten und zweiten Hebel 138, 140 an. Nicht dargestellte Endschalter geben die gewünschte Offenstellung an, so daß die Antriebseinheit 130 von diesen Endschaltern ein Steuersignal erhält, wenn das Wandelement 5 in der gewünschten Offenstellung steht. Entsprechend wird zum Entfernen des Wandelementes aus der Endstellung die Antriebseinheit wieder betätigt und schließt das Wandelement 5. Zusätzlich sind Temperatursensoren oder Rauchmelder vorgesehen, die im Brandfalle ein Signal an die Antriebseinheit abgeben, so daß die Tür automatisch geschlossen wird. Damit zwischen Leibung 102 und Wandelement 5 niemand eingeklemmt wird, ist die Rutschkupplung 137 vorgesehen, die die Bewegung des Wandelementes 5 bei entsprechendem Widerstand unterbricht.To open the wall element 5 receives the Drive unit 130 receives a signal from the electromagnet 129 designed as a switch with metal plate 127 upon contact thereof, and the electric motor 132 then drives the pinion 133 and, via the toothed disk 135 and the shaft 136, the first and second levers 138, 140. Limit switches, not shown, indicate the desired open position, so that the drive unit 130 receives a control signal from these limit switches when the wall element 5 is in the desired open position. Accordingly, to remove the wall element from the end position, the drive unit is actuated again and closes the wall element 5. In addition, temperature sensors or smoke detectors are provided which emit a signal to the drive unit in the event of a fire, so that the door is automatically closed. So that no one is trapped between the reveal 102 and the wall element 5, the slip clutch 137 is provided, which interrupts the movement of the wall element 5 with appropriate resistance.

In Fig. 6 ist der Bewegungsablauf des ersten und zweiten Hebels 138, 140 dargestellt, die derart angeordnet sind, daß der Winkel 142 zwischen ihnen in Richtung zur Schließstellung des Wandelementes 5 gegen Null geht. Durch die angedeutete Sinusbewegung überträgt der Elektromotor im nahezu geschlossenen Zustand des Wandelementes 5 über die Hebel 138, 140 die größte Kraft P auf das Wandelement 5, so daß es in die Leibung 102 hineingezogen wird. Gleichzeitig wird durch das von den Endschaltern abgegebene Signal der Elektromagnet 129 entregt, wodurch die Riegelbolzen 105 freigegeben werden und die Tür verriegelt wird.6 shows the sequence of movements of the first and second levers 138, 140, which are arranged such that the angle 142 between them in the direction of the closed position of the wall element 5 approaches zero. Due to the indicated sine movement, the electric motor transmits the greatest force P to the wall element 5 via the levers 138, 140 in the almost closed state of the wall element 5, so that it is drawn into the reveal 102. At the same time, the solenoid 129 is de-energized by the signal emitted by the limit switches, thereby the locking bolts 105 are released and the door is locked.

Auch wenn eine Antriebseinheit vorgesehen ist, muß das Wandelement von innen zu öffnen sein. Dazu ist neben dem Wandelement 1 ein Hebel 143 vorgesehen, dessen Bewegung bei seiner Betätigung über Schubstangen 144 auf den verschiebbaren Schlitten 134 übertragen wird. Dabei wird der Schlitte 134 zusammen mit dem Elektromotor 132 und dem Ritzel 133 zurückgezogen, so daß das Ritzel 133 mit der Zahnscheibe 135 außer Eingriff tritt. Dadurch kann das Verschließelement unabhängig von der Antriebseinheit 130 per Hand geöffnet werden, so daß auch bei Ausfall der Spannungsversorgung der Antriebseinheit 130 ein Öffnen des Wandelementes 5 möglich ist.Even if a drive unit is provided, the wall element must be able to be opened from the inside. For this purpose, a lever 143 is provided in addition to the wall element 1, the movement of which is transmitted to the displaceable carriage 134 via push rods 144 when it is actuated. The slide 134 is retracted together with the electric motor 132 and the pinion 133 so that the pinion 133 disengages from the toothed disk 135. As a result, the closing element can be opened by hand independently of the drive unit 130, so that the wall element 5 can be opened even if the power supply to the drive unit 130 fails.

In dem beschriebenen Ausführungsbeispiel sitzen alle für die Funktion des Wandelementes wesentlichen Beschläge, Hebel und Aufhängungen bis auf die nach außen geführte Teilwelle 118 mit dem Handrad 119 im Innenraum 6, d.h. im kalten Bereich, wobei die Öffnungsrichtung des Wandelementes nach außen gerichtet ist.In the exemplary embodiment described, all the fittings, levers and suspensions essential for the function of the wall element except for the partial shaft 118 which is guided outwards are seated in the interior 6 with the handwheel 119, i.e. in the cold area, with the opening direction of the wall element facing outwards.
