Abstract

The door construction has multiple door segments (20, 20', 21, 21') guided on guide rails (2, 2') using rollers (7) or sliding elements, where the door segments are held parallel to each other and at a distance from each other. The door segments are movable in two planes and held on the guide rails over suspensions (6, 6', 8, 8') using the rollers or sliding elements. The suspensions implement a gap (4) between a carrier (1) and the guide rail (2) that is adjacent to the carrier, and/or a gap (5) between the two guide rails.

Description

Die Erfindung bezieht sich auf eine Türkonstruktion für einen Aufzug, und zwar für eine Tür einer Aufzugskabine oder für eine Tür eines Aufzugsschachts gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a door construction for an elevator, namely for a door of an elevator car or for a door of a hoistway according to the preamble of claim 1.

Bei bekannten derartigen Türaufhängungen sind im Querschnitt im Wesentlichen C-förmige Aufhängungen vorgesehen, die die Schienen umgreifen. Dies hat zwar den Vorteil, dass die Türen leicht ein- und ausgehängt werden können, was insbesondere dann günstig ist, wenn an den Türen Komponenten angebracht sind, die über elektrische Kabel angeschlossen werden müssen. Dabei ergibt sich jedoch der Nachteil, dass die Aufhängungen mit einem entsprechenden Abstand über die beiden Schienen geführt werden müssen, sodass die Schienen entsprechenden Abstand zum Schacht (im Falle von Aufzugstüren) bzw. zur Kabine (im Falle von Schachttüren) haben müssen. Dadurch ergibt sich aber eine entsprechend große Tiefe der gesamten Konstruktion, die auf Kosten des Innenraums der Kabine geht. Dies ist vor allem beim nachträglichen Einbau von Innentüren ein Problem, wo die Abmessungen nicht mehr geändert werden können.In known door suspensions of this type, cross-sectionally substantially C-shaped suspensions are provided, which surround the rails. Although this has the advantage that the doors can be easily switched on and off, which is particularly beneficial if the doors are mounted components that need to be connected via electrical cables. However, this has the disadvantage that the suspensions must be guided with an appropriate distance over the two rails, so that the rails must have appropriate distance to the shaft (in the case of elevator doors) or to the cabin (in the case of shaft doors). However, this results in a correspondingly large depth of the entire structure, which is at the expense of the interior of the cabin. This is a problem especially when retrofitting internal doors, where the dimensions can not be changed.

Aus den Anmeldungen US 5 878 846 A und US 2005/296038 sind Türaufhängungen bekannt, bei denen zwar die Aufhängungen der schachtfernen Türen in dem Zwischenraum zwischen den Führungsschienen laufen, bei denen jedoch die Aufhängungen der schachtnäheren Türen nach wie vor als abgewinkelte Aufhängungen ausgeführt sind, die die ihnen zugeordnete Führungsschiene auf ihrer Schachtseite umgreifen und daher in Tiefenrichtung entsprechend auftragen.From the registrations US Pat. No. 5,878,846 and US 2005/296038 Door suspensions are known in which although the suspensions of the shaft distant doors in the space between the guide rails run, but where the suspensions of the bay closer doors are still designed as angled suspensions that surround their associated guide rail on its side of the shaft and therefore in the depth direction apply accordingly.

Ziel der Erfindung ist es, diese Nachteile zu vermeiden und eine Türaufhängung der eingangs erwähnten Art vorzuschlagen, die sich durch eine geringe Tiefe auszeichnet.The aim of the invention is to avoid these disadvantages and to propose a door hanger of the type mentioned, which is characterized by a small depth.

Erfindungsgemäß wird dies bei einer Türaufhängung der eingangs erwähnten Art durch die kennzeichnenden Merkmale des Anspruchs 1 erreicht.This is achieved according to the invention in a door hanger of the type mentioned by the characterizing features of claim 1.

Durch die vorgeschlagenen Maßnahmen ergeben sich sehr einfach gestaltete Aufhängungen, bei denen sich beim Hängen der Türsegmente keine nennenswerten Auslenkungen von einer senkrechten Lage ergeben. Die Aufhängungen, die mit den Türsegmenten verbunden sind, können sehr einfach aus einem ebenen Blech hergestellt werden, ohne dass dieses mehrmals abgewinkelt werden muss, wie dies bei den bekannten Lösungen der Fall ist. Da weiters keine Biegekräfte auftreten, können die Aufhängungen aus entsprechend dünnem Blech hergestellt werden. Vor allem aber zeichnet sich die vorgeschlagene Konstruktion durch eine geringe Tiefe aus.The proposed measures result in very simply designed suspensions in which there are no appreciable deflections from a vertical position when hanging the door segments. The suspensions, which are connected to the door segments, can be made very easily from a flat sheet, without this must be angled several times, as is the case with the known solutions. Since further no bending forces occur, the suspensions can be made of thin metal sheet accordingly. Above all, however, the proposed construction is characterized by a small depth.

Normalerweise sind zwei Gruppen von Türsegmenten vorgesehen: die Segmente jeder Gruppe öffnen teleskopartig und bewegen sich stets gemeinsam in gleicher Richtung. Oft ist es aus Platzgründen notwendig, die Türsegmente der einen Gruppe mit unterschiedlicher Breite gegenüber den Türsegmenten der anderen Gruppe auszubilden. In diesem Fall kann der Antrieb der beiden Gruppen schwierig sein, weil die beiden Gruppen unterschiedlich schnell angetrieben werden müssen, wenn die Türsegmente der beiden Gruppen in der gleichen Zeit öffnen sollen. Innerhalb jeder Gruppe sind die Türsegmente miteinander bewegungsschlüssig gekoppelt, sodass nur jeweils ein Türsegment (normalerweise das schnellste) angetrieben werden muss.Normally two groups of door segments are provided: the segments of each group open telescopically and always move together in the same direction. Often it is necessary for reasons of space, the door segments of a group of different width to form the door segments of the other group. In this case, driving the two groups can be difficult because the two groups must be driven at different speeds if the door segments of the two groups are to open at the same time. Within each group, the door segments are coupled with each other in a motion-locking manner, so that only one door segment (usually the fastest) has to be driven.

Bei dieser Ausbildung ist daher bevorzugt vorgesehen, dass die beiden Gruppen von Türsegmenten von einem gemeinsamen Antrieb über eine Stufenscheibe angetrieben sind. Dadurch ist keine aufwändige Untersetzung notwendig und es besteht kein Platzbedarf in Richtung normal zur Ebene der Türsegmente.In this embodiment, it is therefore preferably provided that the two groups of door segments are driven by a common drive via a stepped disc. As a result, no time-consuming reduction is necessary and there is no space requirement in the direction normal to the plane of the door segments.

Die Erfindung wird nun anhand der Zeichnungen näher erläutert. Es zeigt: Fig. 1 schematisch eine axonometrische Darstellung der erfindungsgemäßen Aufhängungen von Türsegmenten; und Fig. 2 schematisch eine Ansicht der Aufhängungen nach Fig. 1.The invention will now be explained in more detail with reference to the drawings. It shows: Fig. 1 schematically an axonometric representation of the suspensions of door segments according to the invention; and Fig. 2 schematically a view of the suspensions after Fig. 1 ,

Die Erfindung wird anhand einer Aufzugskabinentüre erklärt, sie lässt sich aber ebenso bei einer Aufzugsschachttüre anwenden. Es sind zwei Gruppen von Türsegmenten vorgesehen, wobei eine Gruppe die beiden linken (wie in Fig. 2 gesehen) Segmente 20 und 21 und die andere Gruppe die beiden rechten (wie in Fig. 2 gesehen) Segmente 20', 21' umfasst. Die Segmente 20, 21 der einen Gruppe öffnen nach links (wie in Fig. 2 gesehen), die Segmente 20', 21' der anderen Gruppe öffnen nach rechts (wie in Fig. 2 gesehen). Innerhalb einer Gruppe schieben sich die beiden Türsegmente 20, 21 bzw. 20', 21' beim Öffnen teleskopartig voreinander. Die rechten Türsegmente 20', 21' sind schmäler als die linken Türsegmente 20, 21.The invention will be explained with reference to an elevator car door, but it can also be applied to an elevator shaft door. There are two groups of door segments, one group containing the two left (as in Fig. 2 seen) segments 20 and 21 and the other group the two right (as in Fig. 2 seen) segments 20 ', 21' comprises. The segments 20, 21 of one group open to the left (as in FIG Fig. 2 seen), the segments 20 ', 21' of the other group open to the right (as in Fig. 2 seen). Within a group, the two door segments 20, 21 and 20 ', 21' slide telescopically when opening. The right door segments 20 ', 21' are narrower than the left door segments 20, 21.

An einem Träger 1, der an einer nicht weiter dargestellten Aufzugskabine montiert ist, sind zwei Schienen 2, 2' befestigt. Dabei verlaufen die beiden Schienen 2, 2' parallel zueinander und in horizontaler Richtung. Gehalten werden die Schienen 2, 2' von Bolzen 3, wobei diese auch einen Abstand zwischen dem Träger 1 und der Schiene 2 und damit einen Spalt 4 bestimmen. Der Spalt 5 zwischen den beiden schienen 2, 2' wird ebenfalls durch die Bolzen 3 bestimmt.On a support 1, which is mounted on an elevator car, not shown, two rails 2, 2 'are fixed. In this case, the two rails 2, 2 'extend parallel to each other and in the horizontal direction. Are held the rails 2, 2 'of bolt 3, which also determine a distance between the carrier 1 and the rail 2 and thus a gap 4. The gap 5 between the two rails 2, 2 'is also determined by the bolt 3.

Der Spalt 4 zwischen der Schiene 2 und dem Träger 1 wird von Aufhängungen 6, 6' durchsetzt, die mit (randseitigen) Türsegmenten 20, 20' verbunden sind und diese halten. Dabei weisen die Türsegmente 20, 20' und die entsprechenden Aufhängungen 6, 6' unterschiedliche Breiten auf.The gap 4 between the rail 2 and the carrier 1 is penetrated by suspensions 6, 6 ', which are connected to (edge-side) door segments 20, 20' and hold them. The door segments 20, 20 'and the corresponding suspensions 6, 6' have different widths.

An diesen Aufhängungen 6, 6' sind jeweils vier Rollen 7 gehalten, die an der Ober- und der Unterseite der Schiene 2 abrollen. Die oberen Rollen werden als Hängerrollen bezeichnet, weil an diesen das jeweilige Türsegment hängt. Die unteren Rollen werden als Gegenrollen bezeichnet, diese verhindern ein Ausheben der Türsegmente. Anstelle von Rollen 7 können auch Gleitelemente verwendet werden.At these suspensions 6, 6 'each four rollers 7 are held, which roll on the top and bottom of the rail 2. The upper rollers are referred to as trailer rollers because the respective door segment hangs on them. The lower rollers are called counter-rollers, these prevent lifting of the door segments. Instead of rollers 7 and sliding elements can be used.

Der Spalt 5 zwischen den beiden Schienen 2, 2' ist von Aufhängungen 8, 8' durchsetzt, die mit (mittleren) Türsegmenten 21, 21' verbunden sind und diese halten. An den Aufhängungen 8, 8' sind ebenfalls je vier Rollen 7 gehalten, die an der Schiene 2' abrollen. Weiters sind an den Aufhängungen 6, 6', 8, 8' Hebel 9 angeordnet, die mit Kufen 10 zusammenwirken und zusammen einen Kuppler für die Schachttüre bilden, aber nicht Teil der Erfindung sind. Durch diesen Kuppler wird die Schachttüre mitgenommen, wenn die Kabinentüre öffnet, sodass die Schachttüren keinen eigenen Antrieb benötigen. Die Schachttüre ist mit einer Verriegelung versehen, die ein Öffnen verhindert, wenn die Kabine nicht hinter der Schachttüre steht. Auch diese Verriegelung ist nicht Teil der Erfindung.The gap 5 between the two rails 2, 2 'is penetrated by suspensions 8, 8', the with (middle) door segments 21, 21 'are connected and hold them. On the suspensions 8, 8 ', four rollers 7 are also held, which roll on the rail 2'. Furthermore, 9 are arranged on the suspensions 6, 6 ', 8, 8', which cooperate with runners 10 and together form a coupler for the shaft door, but are not part of the invention. Through this coupler, the shaft door is taken when the car door opens, so that the shaft doors do not need their own drive. The shaft door is provided with a lock that prevents it from opening when the cab is not behind the shaft door. This locking is not part of the invention.

Wie man aus Fig. 1 deutlich sieht, wird vor der Schiene 2' nahezu kein Platz benötigt, lediglich die Köpfe der Bolzen 3 stehen geringfügig vor. Dies wird dadurch erreicht, dass die Aufhängungen 8, 8' und 6, 6' durch die beiden Spalte 4, 5 hindurchgehen und nicht die Schienen 2, 2' umgreifen.How to get out Fig. 1 clearly sees, almost no space is required in front of the rail 2 ', only the heads of the bolt 3 are slightly ahead. This is achieved in that the suspensions 8, 8 'and 6, 6' pass through the two gaps 4, 5 and do not surround the rails 2, 2 '.

Wie insbesondere aus Fig. 2 zu ersehen ist, weist die Aufhängung 8', die für ein schmäleres Türsegment 21' vorgesehen ist, eine Auskragung 11 auf, in deren Bereich zwei Rollen 7 angeordnet sind. Dadurch weisen diese Rollen 7 der Aufhängung 8' einen größeren Abstand auf als dies ohne die Auskragung 11 möglich wäre. Damit wird eine bessere Führung des Türsegments 21' erreicht. Die Aufhängung 8, die wie die Aufhängung 8' den Spalt 5 zwischen den Schienen 2' durchsetzt und für ein breiteres Türsegment 21 vorgesehen ist, weist eine Ausnehmung 12 auf, um Platz für die Auskragung 11 zu schaffen.As in particular from Fig. 2 can be seen, the suspension 8 ', which is provided for a narrower door segment 21', a projection 11, in the region of two rollers 7 are arranged. As a result, these rollers 7 of the suspension 8 'at a greater distance than would be possible without the projection 11. For a better guidance of the door segment 21 'is achieved. The suspension 8, which like the suspension 8 'passes through the gap 5 between the rails 2' and is provided for a wider door segment 21, has a recess 12 to make room for the projection 11.

Der Antrieb der beiden Türsegmente 20, 21 bzw. 20', 21' jeder Gruppe erfolgt normalerweise so, dass das mittlere Türsegment 21, 21' aktiv angetrieben wird und das randseitige Türsegment 20, 20' über eine Untersetzung im Verhältnis 2:1 vom mittleren Türsegment 21, 21' mitgenommen wird.The drive of the two door segments 20, 21 and 20 ', 21' of each group is normally such that the middle door segment 21, 21 'is actively driven and the edge-side door segment 20, 20' via a reduction in the ratio 2: 1 from the middle Door segment 21, 21 'is taken.

Wenn nun die Türsegmente 20, 21 und 20', 21' der beiden Gruppen ungleich breit sind, können die beiden mittleren Türsegmente 21, 21' - soll die Öffnungsbewegung bei beiden Gruppen gleich lange dauern - natürlich nicht gleich schnell getrieben werden. Wenn sich die Breite wie 1:2 verhält, könnte das schmälere mittlere Türsegment 21' vom breiteren randseitigen Türsegment 20 angetrieben werden. Dies würde aber zusätzlichen Platz benötigen, der erfindungsgemäß gerade eingespart werden soll.Now, if the door segments 20, 21 and 20 ', 21' of the two groups are unequal width, the two middle door segments 21, 21 '- should the opening movement in both groups take the same length - of course not be driven equally fast. If the width behaves as 1: 2, the narrower middle door segment 21 'could be driven by the wider edge door segment 20. But this would require extra space the invention is just to be saved.

Bevorzugt ist daher ein Antriebsmotor 13, der ein Getriebe in Form einer Stufenscheibe 14 (siehe Fig. 2) antreibt. Die Stufenscheibe 14 kann dabei als Stufen-Riemenscheibe ausgebildet sein, die mittels zweier Riemen 15, 16, die über Umlenkscheiben 17 geführt sind, die mittleren Türsegmente 21, 21' über die Aufhängungen 8, 8', die mit den Riemen 15, 16 verbunden sind, antreibt. Diese Aufhängungen 8, 8' sind bewegungsschlüssig mit den Aufhängungen 6, 6' verbunden. Dadurch werden bei einem Antrieb der Riemen 15, 16 die Aufhängungen 8, 8' bewegt und von diesen z. B. über eine nicht dargestellte übliche Mitnahme, z. B. in Form eines Seils, die Aufhängungen 6', 6 mitgenommen.Therefore, a drive motor 13, which is a gear in the form of a stepped pulley 14 (see Fig. 2 ) drives. The stepped disc 14 can be designed as a stepped pulley, which by means of two belts 15, 16 which are guided over deflecting plates 17, the central door segments 21, 21 'via the suspensions 8, 8', which are connected to the belts 15, 16 are, drives. These suspensions 8, 8 'are connected in a motion-locking manner to the suspensions 6, 6'. As a result, in a drive of the belt 15, 16, the suspensions 8, 8 'are moved and z. B. via a common carrier, not shown, z. B. in the form of a rope, the suspensions 6 ', 6 taken.

Solch ein Antrieb ist normalerweise nur bei der Kabinentüre notwendig. Die Schachttüre wird bewegt, indem die Bewegung der Kabinentüre über einen Kuppler auf die Schachttüre übertragen wird.Such a drive is usually necessary only at the car door. The shaft door is moved by the movement of the car door is transmitted via a coupler on the shaft door.
