Description

Die Erfindung betrifft eine automatische Schiebetür mit einer ersten Öffnungsbreite und mindestens einer weiteren durch manuelle Krafteinwirkung auf den verschiebbaren Türflügel herbeiführbaren weiteren Öffnungsbreite.The invention relates to an automatic sliding door with a first opening width and at least one further opening width that can be brought about by manual force on the displaceable door leaf.

Mit der DE-OS-2 755110 ist eine automatische Sicherheitstür, beispielsweise für ein Kaufhaus, bekanntgeworden, welche aus vier Türflügeln besteht. Im Normalbetrieb sind die zwei äussersten Türflügel fest angeordnet, und die beiden mittleren Türflügel arbeiten als Schiebetür. Die beiden mittleren Türflügel sind ferngesteuert und werden über eine Spindel durch einen Elektromotor angetrieben. Sie verschieben sich beim Öffnen parallel hinter die beiden feststehenden Flügel. Alle vier Türflügel besitzen zusätzlich je an der äusseren Türkante oben und unten Drehzapfen, die ein zusätzliches Ausschwenken jedes einzelnen Flügels gestatten. Die Drehzapfen der beiden festen Türflügel weisen feste Drehlager auf, während der untere Drehzapfen der verschiebbaren Türflügel in einem verschiebbaren Gleitstein gelagert ist und der obere Drehzapfen als Gelenk zwischen einer scherenartigen Verbindung zwischen dem Türflügel und einem den Türflügel tragenden Rollenträger ausgebildet ist. In einem Katastrophenfall können die vier Türflügel, sobald die beiden Schiebetürflügel aus einer Endarretierung ausgefahren sind, mechanisch aufgedrückt und ausgeschwenkt werden. Die grösste Öffnungsbreite wird erreicht, wenn das Ausschwenken der vier Türflügel erfolgt, wenn die beiden mittleren Schiebetürflügel bereits ganz aufgefahren sind.With DE-OS-2 755110 an automatic security door, for example for a department store, has become known, which consists of four door leaves. In normal operation, the two outermost door leaves are fixed, and the two middle door leaves work as sliding doors. The two middle door leaves are remotely controlled and are driven by an electric motor via a spindle. When opening, they move parallel behind the two fixed wings. All four door leaves also have pivots on the outer edge of the door at the top and bottom, which allow each door to be swung out additionally. The pivots of the two fixed door leaves have fixed pivot bearings, while the lower pivot of the sliding door leaves is mounted in a sliding sliding block and the upper pivot is designed as a joint between a scissor-like connection between the door leaf and a roller support carrying the door leaf. In the event of a catastrophe, the four door leaves can be mechanically pushed open and pivoted out as soon as the two sliding door leaves have been extended from an end stop. The greatest opening width is achieved when the four door leaves are swung out, when the two middle sliding door leaves are already fully open.

Der Nachteil dieser bekannten Einrichtung liegt darin, dass sie nicht geeignet wäre für den Einsatz in einer Aufzugsanlage und dass sie nach jedem Gebrauch einer grösseren Öffnungsbreite manuell in den ursprünglichen, normalen Betriebszustand zurückzuführen ist.The disadvantage of this known device is that it would not be suitable for use in an elevator installation and that after each use of a larger opening width it can be manually returned to the original, normal operating state.

Für personenbegleitete Warenaufzüge sind Schachtabschlüsse bekannt, bei welchen in den einzelnen Stockwerken schwenkbare, nicht automatische, einflügelige Schachttüren vorgesehen sind, die nicht die ganze Öffnungsbreite der Aufzugskabine abdecken. Die restliche Öffnungsbreite wird durch einen im Normalbetrieb nicht verwendeten, mechanisch blockierten und elektrisch abgesicherten zusätzlichen Schwenkflügel geschlossen. Im Bedarfsfall kann man diesen zweiten Türflügel durch einfache Handgriffe ebenfalls öffnen und so die ganze Öffnungsbreite der Kabine für sperrige Güter ausnutzen.Shaft closures are known for goods lifts accompanied by persons, in which pivotable, non-automatic, single-leaf shaft doors are provided on the individual floors, which do not cover the entire opening width of the elevator car. The remaining opening width is closed by a mechanically blocked and electrically secured additional swivel wing that is not used in normal operation. If necessary, this second door leaf can also be opened with simple hand movements and thus the entire opening width of the cabin can be used for bulky goods.

Der Nachteil dieser Einrichtung liegt ebenfalls darin, dass der ursprüngliche, normale Betriebszustand nach dem Gebrauch der grossen Öffnungsbreite durch manuelle Manipulationen wieder hergestellt werden muss. Ein weiterer Nachteil liegt noch darin, dass sich diese Einrichtung für Aufzüge mit Schacht- und zusätzlich mit Kabinenabschlüssen ebenfalls nicht eignen würde.The disadvantage of this device is also that the original, normal operating state has to be restored by manual manipulation after the large opening width has been used. Another disadvantage is that this device would also not be suitable for elevators with shaft and cabin closures.

Der Erfindung liegt die Aufgabe zugrunde, eine Schiebetür für eine Aufzugsanlage für mehr als eine Öffnungsbreite vorzuschlagen, welche sich für Aufzüge mit Schacht- und Kabinentüren eignet und welche nach jeder Öffnung, gleich welcher Öffnungsbreite, automatisch stets den für die kleinste Öffnungsbreite vorgesehenen Betriebszustand herstellt.The invention has for its object to propose a sliding door for an elevator system for more than one opening width, which is suitable for lifts with shaft and cabin doors and which automatically produces the operating state intended for the smallest opening width after each opening, regardless of opening width.

Diese Aufgabe wird durch die im Anspruch 1 gekennzeichnete Erfindung gelöst.This object is achieved by the invention characterized in claim 1.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass die automatische Tür in jede Öffnungsbreite elektrisch angetrieben ist, dass sie aus Zeitersparnisgründen für den Normalfall stets die kleinste eingestellte Öffnungsbreite anfährt, dass eine grössere Öffnungsbreite, sobald die erste Öffnungsbreite erreicht ist, allein durch einen manuellen Druck auf den Türflügel in der Richtung der Öffnungsbewegung angefahren wird, und dass sie nach jeder Schliessbewegung automatisch stets wieder die erste Öffnungsbreite anfährt.The advantages achieved by the invention are essentially to be seen in the fact that the automatic door is electrically driven in every opening width, that for reasons of time saving it always approaches the smallest opening width set for normal use, that a larger opening width as soon as the first opening width is reached, only by manual pressure on the door leaf in the direction of the opening movement, and that after each closing movement it automatically moves to the first opening width.

In der Fig. 1 ist mit 1 ein Türflügel einer Kabinentür einer Aufzugsanlage bezeichnet. Der Türflügel 1 ist mit Rollen 2 auf einer am Türrahmen 20 angeordneten Tragschiene 3 schiebbar gelagert. Am Türflügel 1 ist ein Türmitnehmer 4 angeordnet, an welchem ein von einem Antriebsmittel 6 angetriebener Mitnehmerbügel 5 angelenkt ist. Der Mitnehmerbügel 5 ist am Gelenkpunkt 6. 1 mit dem Antriebsmittel 6 verbunden. Die Richtung des Pfeiles 7 zeigt die Öffnungs-Bewegung des Türflügels 1 an. Das Antriebsmittel 6 ist um zwei Umlenkrollen 8, 9 gelegt und wird durch eine Treibrolle 10 angetrieben. Die Treibrolle 10 wird ihrerseits über ein Riemenvorgelege 11 von einem Elektromotor 12 in Bewegung gesetzt. Zwei neben der Treibrolle 10 auf je einen Trum des Antriebsmittels 6 wirkende Spannrollen 13, 14 geben dem Antriebsmittel 6 stets die richtige Spannung. Am Antriebsmittel 6 ist ein Nocken 15 vorgesehen, welcher zwei Anschlagflächen 15.2 und eine Gleitfläche 15.1 aufweist. Der Nocken 15 arbeitet mit einem an einem Drehzapfen 17 schwenkbar gelagerten Hebel 16 zusammen. Der Hebel 16 weist eine Steuerseite und eine Anschlagseite auf. Die Anschlagseite ragt in einer durch die Schwerkraft des Hebels 16 und/oder durch die Rückstellkraft einer Feder 25 bestimmten Ruhelage in die Bewegungsbahn des Nockens 15 des Antriebsmittels 6 hinein. Ein Schalter 18 und der Drehzapfen 17 sind an einem an einer Tragkonstruktion 21 angeordneten Blechträger 19 befestigt. An der gleichen mit dem Türrahmen 20 verbundenen Tragkonstruktion 21 sind auch der Elektromotor 12, das Riemenvorgelege 11, die Umlenkrollen 8, 9 und die Spannrollen 13, 14 aufgebaut.In Fig. 1, 1 denotes a door wing of a car door of an elevator system. The door leaf 1 is slidably mounted with rollers 2 on a mounting rail 3 arranged on the door frame 20. A door driver 4 is arranged on the door leaf 1, to which a driver bracket 5 driven by a drive means 6 is articulated. The driver bracket 5 is connected to the drive means 6 at the hinge point 6.1. The direction of arrow 7 indicates the opening movement of the door leaf 1. The drive means 6 is placed around two deflection rollers 8, 9 and is driven by a drive roller 10. The drive roller 10 is in turn set in motion by an electric motor 12 via a belt transmission 11. Two tensioning rollers 13, 14 which act next to the drive roller 10 on each strand of the drive means 6 always give the drive means 6 the correct tension. A cam 15 is provided on the drive means 6, which has two stop surfaces 15.2 and a sliding surface 15.1. The cam 15 cooperates with a lever 16 pivotally mounted on a pivot 17. The Lever 16 has a control side and a stop side. In a rest position determined by the gravity of the lever 16 and / or by the restoring force of a spring 25, the stop side projects into the movement path of the cam 15 of the drive means 6. A switch 18 and the pivot pin 17 are fastened to a sheet metal support 19 arranged on a support structure 21. The electric motor 12, the belt transmission 11, the deflection rollers 8, 9 and the tensioning rollers 13, 14 are also constructed on the same supporting structure 21 connected to the door frame 20.

In den Figuren 2, 3 und 4 ist mit 19 der Blechträger für den Schalter 18 und den Hebel 16 bezeichnet. Der Hebel 16 ist am Drehzapfen 17 schwenkbar gelagert und weist auf der Steuerseite eine Einschaltkurve 16.1 zum Einschalten und eine Ausschaltkurve 16.2 zum Ausschalten des Schalters 18 auf. In der Ruhelage des Hebels 16 liegt auf der Einschaltkurve 16.1 eine Kontaktfahne 18.1 des Schalters 18 auf. Beim Schwenken des Hebels 16 durch den Nocken 15 des Antriebsmittels 6 gleitet die Kontaktfahne 18.1 je nach der schwenkrichtung auf der Ausschaltkurve 16.2 und/oder auf der Einschaltkurve 16.1. Die Anschlagseite des Hebels 16 besteht aus zwei parallelen Anschlagflächen 16.4 und einer Gleitkurve 16.3. Je ein Pfeil 22 und 23 geben die Bewegungsrichtung des Antriebsmittels 6 und des Nockens 15 beim Öffnen des Türflügels, und ein Pfeil 24 gibt die Bewegungsrichtung des Antriebsmittels 6 und des Nockens 15 beim schliessen des Türflügels 1 an. Zur Unterstützung der Schwerkraft des Hebels 16 dient die Rückstellkraft einer zwischen dem Hebel 16 und dem Blechträger 19 angeordneten Feder 25.In Figures 2, 3 and 4, 19 denotes the sheet metal support for the switch 18 and the lever 16. The lever 16 is pivotally mounted on the pivot pin 17 and has a switch-on curve 16.1 for switching on and a switch-off curve 16.2 for switching off the switch 18 on the control side. In the rest position of the lever 16, there is a contact tab 18.1 of the switch 18 on the switch-on curve 16.1. When the lever 16 is pivoted by the cam 15 of the drive means 6, the contact lug 18.1 slides on the switch-off curve 16.2 and / or on the switch-on curve 16.1 depending on the pivoting direction. The stop side of the lever 16 consists of two parallel stop surfaces 16.4 and a sliding curve 16.3. One arrow 22 and 23 each indicate the direction of movement of the drive means 6 and the cam 15 when the door leaf is opened, and an arrow 24 indicates the direction of movement of the drive means 6 and the cam 15 when the door leaf 1 is closed. The restoring force of a spring 25 arranged between the lever 16 and the sheet metal support 19 serves to support the gravity of the lever 16.

Die vorstehend beschriebene Einrichtung arbeitet wie folgt: In der Fig. 1 ist der Türflügel 1 in seiner geschlossenen Stellung dargestellt. Beim Öffnen des Türflügels 1 bewegt sich das Antriebsmittel 6, angetrieben durch die vom Elektromotor 12 über das Riemenvorgelege 11 in Drehung versetzte Treibrolle 10, in der Richtung des Pfeiles 7. Dabei nimmt der einerseits am Gelenkpunkt 6.1 mit dem Antriebsmittel 6 verbundene und anderseits am Türmitnehmer 4 angelenkte Mitnehmerbügel 5 den Türflügel 1 mit, bis der Nocken 15 des Antriebsmittels 6 den Hebel 16 erreicht. Diese Stellung ist in Fig. 2 grösser dargestellt. Der Nocken 15 schwenkt den Hebel 16 im Gegenuhrzeigersinn, wobei die auf der Einschaltkurve 16.1 des Hebels 16 ruhende Kontaktfahne 18.1 des Schalters 18 von der Einschaltkurve 16.1 auf die Ausschaltkurve 16.2 gleitet und den Schalter 18 unterbricht. Der Elektromotor 12 wird ausgeschaltet und der Türflügel läuft zusammen mit dem Antriebsmittel 6 bis zum völligen Stillstand aus und legt einen Auslaufweg von max. ca. 60 mm zurück. Der Nocken 15 des Antriebsmittels 6 schwenkt dabei den Hebel 16 weiter, bis die in Fig. 3 dargestellte Stillstandstellung erreicht ist, bei welcher der Hebel 16 mit der Abrundung zwischen der Anschlagfläche 16.4 und der Gleitkurve 16.3 am Rande der Gleitfläche 15.1 des Nockens 15 aufliegt. Der Schalter 18 bleibt während des ganzen Auslaufweges und im Stillstand zwangsläufig ausgeschaltet. Der Elektromotor 12 kann nur noch in der Gegenrichtung, also für die Schliessbewegung, eingeschaltet werden. Die erreichte Türöffnung entspricht der für den Normalbetrieb vorgesehenen ersten Offenstellung mit einer Öffnungsbreite, die kleiner ist als die Gesamtbreite des Türflügels 1. Für die Schliessbewegung ist ein Zusatzimpuls nötig, bei welchem der Elektromotor 12 in der Gegenrichtung eingeschaltet wird, wobei sich das Antriebsmittel 6 und der Nocken 15 in der zum Pfeil 23 entgegengesetzten Richtung bewegen. Der Hebel 16 gleitet durch sein Eigengewicht und/oder durch die Rückstellkraft der Feder 25 auf der Gleitfläche 15.1 und auf einer Kante des Nockens 15 und schwenkt im Uhrzeigersinn wieder in die Ruhelage ein, wie sie in Fig. 2 dargestellt ist. Die Kontaktfahne 18.1 des Schalters 18 gleitet von der Ausschaltkurve 16.2 auf die Einschaltkurve 16.1 und schaltet den Schalter 18 wieder ein und bereitet ihn dadurch für eine weitere Öffnungsbewegung vor.The device described above works as follows: In Fig. 1 the door leaf 1 is shown in its closed position. When the door leaf 1 is opened, the drive means 6, driven by the drive roller 10 set in rotation by the electric motor 12 via the belt transmission 11, moves in the direction of the arrow 7 4 articulated driver bracket 5 with the door leaf 1 until the cam 15 of the drive means 6 reaches the lever 16. This position is shown larger in Fig. 2. The cam 15 pivots the lever 16 in a counterclockwise direction, the contact tab 18.1 of the switch 18 resting on the switch-on curve 16.1 of the lever 16 sliding from the switch-on curve 16.1 to the switch-off curve 16.2 and interrupting the switch 18. The electric motor 12 is switched off and the door leaf runs together with the drive means 6 to a complete standstill and sets an outlet path of max. approx. 60 mm back. The cam 15 of the drive means 6 pivots the lever 16 further until the standstill position shown in FIG. 3 is reached, in which the lever 16 rests with the rounding between the stop surface 16.4 and the sliding curve 16.3 on the edge of the sliding surface 15.1 of the cam 15. The switch 18 remains inevitably switched off during the entire run-out path and at a standstill. The electric motor 12 can only be switched on in the opposite direction, that is to say for the closing movement. The door opening achieved corresponds to the first open position provided for normal operation with an opening width that is smaller than the total width of the door leaf 1. An additional pulse is required for the closing movement, in which the electric motor 12 is switched on in the opposite direction, the drive means 6 and move the cam 15 in the opposite direction to the arrow 23. The lever 16 slides by its own weight and / or by the restoring force of the spring 25 on the sliding surface 15.1 and on an edge of the cam 15 and swivels clockwise back into the rest position, as shown in Fig. 2. The contact tab 18.1 of the switch 18 slides from the switch-off curve 16.2 to the switch-on curve 16.1 and switches the switch 18 on again, thereby preparing it for a further opening movement.

Für den Transport von sperrigen Gütern kann es vorkommen, dass die bei der ersten Offenstellung erreichte Öffnungsbreite nicht mehr genügt und eine grössere Öffnungsbreite nötig wird. Der Türflügel 1 wird vorerst, wie oben beschrieben, für den Normalbetrieb geöffnet, bis die erste Offenstellung und die Lage des Hebels 16 gemäss Fig. 3 erreicht ist. Nun wird der Türflügel 1 durch manuelle Krafteinwirkung in der Öffnungsrichtung um einige Millimeter verschoben, was beim beschriebenen Antriebsaggregat ohne grosse Kraftanstrengung möglich ist. Gleichzeitig wird das Antriebsmittel 6 und mit ihm der Nocken 15 in der Richtung des Pfeiles 23 verschoben, bis der Hebel 16 durch sein Eigengewicht mit der Gleitfläche 16.3 an der oberen Kante des Nockens 15 vorbeigleitet. Der Hebel 16 nimmt wieder die Ruhelage gemäss den Fig. 1 oder 2 ein. Die Kontaktfahne 18.1 des Schalters 18 gleitet von der Ausschaltkurve 16.2 auf die Einschaltkurve 16.1, und der Schalter 18 schaltet wieder ein. Der Elektromotor 12 beginnt sofort in der Öffnungsrichtung weiterzulaufen. Der Türflügel 1 bewegt sich über die erste Offenstellung hinaus, bis der Nocken 15 des Antriebsmittels 6 einen weiteren Hebel oder einen Endschalter betätigt und der Türflügel 1 in einer grösseren Offenstellung anhält.For the transport of bulky goods, it may happen that the opening width achieved in the first open position is no longer sufficient and a larger opening width is necessary. As described above, the door leaf 1 is initially opened for normal operation until the first open position and the position of the lever 16 according to FIG. 3 is reached. Now the door leaf 1 is moved by a manual force in the opening direction by a few millimeters, which is possible in the drive unit described without great effort. At the same time, the drive means 6 and with it the cam 15 are displaced in the direction of the arrow 23 until the lever 16 slides past the upper edge of the cam 15 due to its own weight with the sliding surface 16.3. The lever 16 resumes the rest position according to FIGS. 1 or 2. The contact tab 18.1 of the switch 18 slides from the switch-off curve 16.2 to the switch-on curve 16.1, and the switch 18 switches on again. The electric motor 12 immediately begins to run in the opening direction. The door leaf 1 moves beyond the first open position until the cam 15 of the drive means 6 actuates a further lever or a limit switch and the door leaf 1 stops in a larger open position.

Die Schliessbewegung des Türflügels 1 wird durch einen Schliessimpuls eingeleitet. Der Elektromotor 12 dreht in der Gegenrichtung und bewegt das Antriebsmittel 6 in der zum Pfeil 7 entgegengesetzten Richtung. Der Nocken 15 des Antriebsmittels 6 wandert während der Schliessbewegung, wie in der Fig. 4 dargestellt, in der Richtung des Pfeiles 24 an der ersten Schaltvorrichtung vorbei, indem der Hebel 16 im Uhrzeigersinn geschwenkt wird, bis die Kante der Gleitfläche 15.1 des Nockens 15 die Gleitkurve 16.3 des Hebels 16 freigibt und der Hebel 16 durch sein Eigengewicht im Gegenuhrzeigersinn wieder in die Ruhelage zurückschwenkt. Während diesen Schwenkbewegungen gleitet die Kontaktfahne 18.1 des Schalters 18 stets auf der Einschaltkurve 16.1 des Hebels 16. Der Schalter 18 wird dabei nie unterbrochen. Die Schliessbewegung dauert an, bis der Türflügel 1 wieder geschlossen ist. Bei der nächsten Öffnungsbewegung wird der Türflügel automatisch wieder nur bis zur ersten Offenstellung geöffnet.The closing movement of the door leaf 1 is initiated by a closing pulse. The electric motor 12 rotates in the opposite direction and moves the drive means 6 in the direction opposite to the arrow 7. The cam 15 of the drive means 6 moves during the closing movement, as shown in FIG. 4, in the direction of arrow 24 past the first switching device by pivoting the lever 16 clockwise until the edge of the sliding surface 15.1 of the cam 15 Glide curve 16.3 of the lever 16 releases and the lever 16 pivots back into its rest position counterclockwise due to its own weight. During these swiveling movements, the contact tab 18.1 of the switch 18 always slides on the switch-on curve 16.1 of the lever 16. The switch 18 is never interrupted. The closing movement continues until the door leaf 1 is closed again. With the next opening movement, the door leaf is automatically opened only until the first open position.

Ist beispielsweise für eine längere Zeitdauer eine grössere Öffnungsbreite erforderlich, kann der Hebel 16 für eine kleine Öffnungsbreite durch einen Schlüssel oder durch einen Elektromagneten in einer Position fixiert werden, in welcher der Hebel 16 ausserhalb der Bewegungsbahn des Nockens 15 des Antriebsmittels 6 zu liegen kommt und der Schalter 18 gleichzeitig eingeschaltet bleibt. Dadurch wird die Schaltvorrichtung für eine kleine Öffnungsbreite stillgesetzt und der Türflügel 1 stets für eine grössere Öffnungsbreite geöffnet.If, for example, a larger opening width is required for a longer period of time, the lever 16 for a small opening width can be fixed by a key or by an electromagnet in a position in which the lever 16 comes to lie outside the movement path of the cam 15 of the drive means 6 and the switch 18 remains on at the same time. As a result, the switching device is stopped for a small opening width and the door leaf 1 is always opened for a larger opening width.

Es ist ohne weiteres möglich, anstelle der beschriebenen einflügeligen Schiebetür eine andere Schiebetür mit beispielsweise zwei zentral öffnenden oder teleskopisch öffnenden Türflügeln vorzusehen.Instead of the single-leaf sliding door described, it is readily possible to provide another sliding door with, for example, two centrally opening or telescopically opening door leaves.

Ebenso ist es denkbar, dass der im Ausführungsbeispiel zur Betätigung des Hebels beschriebene Nocken statt am bandförmigen Antriebsmittel direkt am Türflügel angeordnet werden könnte, wobei der schwenkbar gelagerte Hebel und der zugehörige Schalter spiegelbildlich am Türrahmen zu befestigen wären.It is also conceivable that the cam described in the exemplary embodiment for actuating the lever could be arranged directly on the door wing instead of on the belt-shaped drive means, the pivotably mounted lever and the associated switch having to be attached to the door frame in mirror image.
