Eine Schiebetüranordnung der vorstehend genannten Art ist aus der Praxis grundsätzlich bekannt, vergleiche beispielsweise US 3 166 155 A , DE 198 11338 A1 oder EP 1288422 A1 . Bei diesen Schiebetüranordnungen hat es sich bewährt, eine wandseitige Durchgangsöffnung mit einer Zarge zu versehen und oberhalb der wandseitigen Durchgangsöffnung eine Laufschiene anzuordnen, an der eine Schiebetür verschiebbar gelagert ist. Wird die Schiebetür nun geöffnet, verfügen die aus der Praxis bekannten Schiebetüranordnungen über einen Feststellmechanismus, mit dem die Schiebetür in einer Öffnungsposition arretierbar bzw. haltbar ist, so dass die Durchgangsöffnung permanent freigegeben ist. Durch manuelle Auslösung oder im Falle eines Brandes kann der Feststellmechanismus gelöst werden, so dass die Schiebetür in eine Verschlussposition gefahren wird, in der sie die Durchgangsöffnung vollständig verschließt. Die aus der Praxis bekannten Schiebetüren weisen ein hohes Eigengewicht auf, weswegen das Öffnen und das Schließen dieser Türen sehr kraftaufwendig ist. Die Elektrifizierung des Antriebs der Schiebetür ist jedoch kritisch, da ein zuverlässiges Öffnen und Schließen der Schiebetür auch dann gewährleistet sein muss, wenn der Antrieb zum Verfahren der Schiebetür beispielsweise in einem Brandfall wegen eines Stromausfalls nicht zur Verfügung steht.A sliding door arrangement of the aforementioned type is basically known in practice, see for example US 3,166,155 A .

If the sliding door is now opened, the sliding door arrangements known from practice have a locking mechanism with which the sliding door can be locked or held in an open position, so that the passage opening is permanently released. By manual release or in case of fire, the locking mechanism can be solved, so that the sliding door in a Closing position is moved, in which it completely closes the passage opening. The known from practice sliding doors have a high weight, which is why the opening and closing of these doors is very power consuming. However, the electrification of the drive of the sliding door is critical, since a reliable opening and closing of the sliding door must be ensured even if the drive for moving the sliding door, for example in a fire due to a power failure is not available.

In den Fig. 1 bis 3 ist dargestellt, dass die Antriebseinrichtung 5 ein zu dem Kopplungselement komplementär ausgebildetes Komplementärkopplungselement aufweist. Das Komplementärkopplungselement ist gemäß dem Ausführungsbeispiel als Permanentmagnet bzw. Haftmagnet 16 ausgebildet. Das Kopplungselement bzw. der Elektromagnet 12 ist an die Antriebseinrichtung 5 gemäß den Fig. 1, 2 und 4 koppelbar bzw. gekoppelt, wenn die Halteplatte 13 des eingeschalteten Elektromagneten 12 an dem Haftmagnet 16, wie in Fig. 4 dargestellt, anliegt. Um den Elektromagneten 12 einzuschalten oder auszuschalten, ist der Elektromagnet 12 mit einer Stromleitung L an die Steuereinrichtung 7 angeschlossen, so dass der Elektromagnet 12 von der Steuereinrichtung 7 mit elektrischem Strom versorgbar ist. In den Fig. 1 bis 4 ist gezeigt, dass die Stromleitung L in eine Energiekette E geführt ist, um eine präzise Führung der Stromleitung L zu gewährleisten und ein Abknicken der Stromleitung L zu verhindern. Die Antriebseinrichtung 5 umfasst fernerhin einen Gleichstrommotor (nachfolgend Motor) 17, mit dem der Haftmagnet 16 entlang einer Führungsschiene 18 verfahrbar ist. Durch das Verfahren des Haftmagneten 16 und des gemäß Fig. 4 daran angekoppelten Elektromagneten 12 ist eine Verschiebung der Schiebetür 2 aus der Verschlussposition gemäß Fig. 1 in die Öffnungsposition gemäß Fig. 2 und umgekehrt möglich. Das Verfahren der Schiebetür 2 kann beispielsweise und gemäß den Figuren durch den Handschalter 19, der in den Fig. 1 bis 3 dargestellt ist, aktiviert werden. Ein Schaltsignal des Handschalters 19 wird vorzugsweise und gemäß dem Ausführungsbeispiel auf die Steuereinrichtung 7 übertragen, durch die die Antriebseinrichtung 5 mit dem Motor 17 gesteuert wird.In the Fig. 1 to 3 it is shown that the drive device 5 has a complementary to the coupling element formed complementary coupling element. The complementary coupling element is formed according to the embodiment as a permanent magnet or magnet 16. The coupling element or the electromagnet 12 is connected to the drive device 5 according to FIGS Fig. 1 . 2 and 4 coupled or coupled, when the holding plate 13 of the switched-on electromagnet 12 to the magnet 16, as in Fig. 4 shown, applied. In order to turn the electromagnet 12 on or off, the electromagnet 12 is connected to the control device 7 with a power line L, so that the electromagnet 12 can be supplied with electrical power by the control device 7. In the Fig. 1 to 4 is 2, that the power line L is led into a power chain E in order to ensure precise guidance of the power line L and to prevent the power line L from bending. The drive device 5 further comprises a DC motor (hereinafter motor) 17, with which the magnet 16 is movable along a guide rail 18.

Weiterhin ist in den Fig. 1 bis 3 dargestellt, dass die Schiebetür 2 eine Rückstelleinrichtung mit einem Kontergewicht 20 aufweist. Wird die Schiebetür 2 aus der Verschlussposition gemäß Fig. 1 in die Öffnungsposition gemäß Fig. 2 bewegt, wird das Kontergewicht 20 angehoben. In Fig. 1 ist der Abstand des Kontergewichts 20 zu einem Fußboden geringer als der Abstand zwischen dem Kontergewicht 20 und dem Fußboden in der Öffnungsposition gemäß Fig. 2. Durch die Gewichtskraft wird das Kontergewicht 20 in Richtung des Fußbodens gezogen, so dass ausgehend von der Öffnungsposition gemäß Fig. 2 die in dem Kontergewicht 20 gespeicherte potentielle Energie derart nutzbar ist, dass die Schiebetür 2 aus der Öffnungsposition in die Verschlussposition überführbar ist.Furthermore, in the Fig. 1 to 3 illustrated that the sliding door 2 has a restoring device with a counterweight 20. If the sliding door 2 from the closed position according to Fig. 1 in the opening position according to Fig. 2 moves, the counterweight 20 is raised. In Fig. 1 the distance of the counterweight 20 to a floor is less than the distance between the counterweight 20 and the floor in the open position according to FIG Fig. 2 , By the weight of the counterweight 20 is pulled in the direction of the floor, so that starting from the opening position according to Fig. 2 the potential energy stored in the counterweight 20 can be used in such a way that the sliding door 2 can be transferred from the open position into the closed position.

In Fig. 3 ist dargestellt, dass der Elektromagnet 12 durch die Steuereinheit 7 stromfrei geschaltet ist, so dass zwischen dem Elektromagneten 12 und dem Haftmagneten 16 der Antriebseinrichtung 5 kein Kraftschluss besteht. Gemäß Fig. 3 wird der Elektromagnet 12 stromfrei durch die Steuereinrichtung 7 geschaltet, wenn der Steuereinrichtung 7 von einem nicht dargestellten Sensor ein unzulässig hoher Temperaturwert oder eine unzulässig hohe Rauchkonzentration übermittelt wird. Die Masse des Kontergewichts 20 ist bei der erfindungsgemäßen Schiebetür 2 derart bemessen, dass das Kontergewicht 20 bei stromfreiem Elektromagnet 12 in der Öffnungsposition bedingt durch die Gewichtskraft in Richtung des Fußbodens gezogen wird bzw. fällt. Die durch das Absenken des Kontergewichts 20 frei werdende Energie bewirkt eine Verlagerung der Schiebetür 2 aus der Öffnungsposition in die Verschlussposition. Wird der Elektromagnet 12 in der Verschlussposition gemäß Fig. 3 wieder mit einem Stromfluss beaufschlagt und folglich aktiviert bzw. magnetisch, ist eine erneute Ankopplung des Haftmagneten 16 der Antriebseinrichtung 5 an den Elektromagneten 12 möglich, indem der Haftmagnet 16 mit dem Motor bzw. Gleichstrommotor 17 an die Haftplatte 13 des Elektromagneten 12 herangefahren wird.In Fig. 3 It is shown that the electromagnet 12 is de-energized by the control unit 7, so that there is no frictional connection between the electromagnet 12 and the holding magnet 16 of the drive means 5. According to Fig. 3 the electromagnet 12 is switched without current through the control device 7 when the control device 7 is transmitted from an unillustrated sensor an inadmissibly high temperature value or an inadmissibly high smoke concentration. The mass of the counterweight 20 is dimensioned in the sliding door 2 according to the invention such that the counterweight 20 is pulled in the open position due to the force of gravity in the direction of the floor with electromagnet 12 in the open position or falls. The energy released by the lowering of the counterweight 20 causes a displacement of the sliding door 2 from the open position to the closed position. If the solenoid 12 in the closed position according to Fig. 3 again subjected to a current flow and thus activated or magnetically, a re-coupling of the holding magnet 16 of the drive means 5 to the electromagnet 12 is possible by the magnet 16 with the motor or DC motor 17 is moved up to the adhesive plate 13 of the electromagnet 12.
