Description

Die Erfindung betrifft eine Fahreinrichtung mit einem Antriebssystem mit einer Forderkette nach dem Oberbegriff des Anspruchs 1.The invention relates to a driving device with a drive system with a conveyor chain according to the preamble of claim 1.

Fahreinrichtungen im Sinne der Erfindung, die auch als Fördereinrichtungen bezeichnet werden können, sind Fahrtreppen und Fahrsteige mit einer Vielzahl von Tritteinheiten bzw. Fahrtreppenstufen oder Fahrsteigpaletten, die zu einem Endlosförderer verbunden sind. Benutzer der Fahreinrichtungen stehen auf Trittflächen der Tritteinheiten oder sie stehen oder gehen auf den Fahrsteigpaletten in gleicher Richtung wie die Fahreinrichtungen selbst.Driving devices in the sense of the invention, which can also be referred to as conveyors, are escalators and moving walks with a plurality of step units or escalator steps or moving platform pallets which are connected to an endless conveyor. Users of the driving devices stand on treads of the kiting units or they stand or walk on the pavement pallets in the same direction as the driving devices themselves.

Bei Fahrtreppen bilden die Fahrtreppenstufen Tritteinheiten, im Weiteren als Stufen bezeichnet, und bei Fahrsteigen bilden die Fahrsteigpaletten Tritteinheiten, im Weiteren als Paletten bezeichnet. Fahrtreppen überwinden mit relativ grossem Neigungswinkel grössere Höhenunterschiede wie ganze Stockwerke oder mehr. Fahrsteige verlaufen horizontal oder leicht schräg, aber im Allgemeinen mit geringerem Neigungswinkel als Fahrtreppen.For escalators, the escalator steps form stepping units, hereinafter referred to as steps, and for moving walkways, the moving walkway pallets form stepping units, hereinafter referred to as pallets. Escalators overcome with a relatively large inclination larger height differences as whole floors or more. Moving walkways are horizontal or slightly inclined, but generally at a lower incline than escalators.

Typischerweise umfassen solche Fahreinrichtungen Stufen- oder Palettenketten, mittels denen die Stufen oder Paletten in Förderrichtung bewegt werden. Im Folgenden werden lediglich Stufenketten erwähnt, worunter jedoch auch Palettenketten verstanden werden sollen. Diese Stufenketten werden angetrieben und sind in gleichmässigen Abständen mit sogenannten Laufrollen versehen. Die Laufrollen rollen oder fahren entlang von Laufschienen. Im Bereich der Enden der Fahreinrichtungen laufen die Stufenketten mit den Laufrollen um Kettenräder oder Umlenkungen herum und vollziehen so einen Richtungswechsel um 180 Grad.Typically, such vehicles include step or pallet chains by means of which the steps or pallets are moved in the conveying direction. In the following, only step chains are mentioned, by which, however, pallet chains are to be understood. These step chains are driven and are provided at regular intervals with so-called rollers. The rollers roll or travel along rails. Run in the area of the ends of the driving facilities the step chains with the rollers around sprockets or deflections around and thus make a change of direction by 180 degrees.

Eine Fahreinrichtung mit Stufen- oder Palettenketten ist aus der Patentaruneldung DE-100 63 844 bekannt. In dieser Patentanmeldung geht es primär darum, die Anzahl der Kettenelemente, respektive Kettenglieder, zu reduzieren, die pro Stufe oder Palette zum Einsatz kommen.A driving device with stepped or pallet chains is from the patent application DE-100 63 844 known. In this patent application, it is primarily about reducing the number of chain elements, or chain links, which are used per stage or pallet.

Es wird als Nachteil bisheriger Fahzeinrichtungen empfunden, dass die Stufenketten samt vieler Laufrollen aus vielen Einzelteilen bestehen, die teuer und kostspielig und arbeitsaufwendig sind. Anderseits ist aber die Stufenkette mit den daran befindlichen Elementen eines der wesentlichen Bauteile des Fördersystems einer Fahreinrichtung, und gewisse Änderungen an diesem komplexen Antriebssystem bzw. Fördersystem könnten unerwünschte Konsequenzen haben, wie reduzierte Laufruhe und eventuell auch ungleichmässigen Lauf sowie eine erhöhte Geräuschentwicklung.It is felt as a disadvantage of existing Fahzeinrichtungen that the step chains including many rollers made of many items that are expensive and expensive and laborious. On the other hand, but the step chain with the elements thereon is one of the essential components of the conveyor system of a driving device, and certain changes to this complex drive system or conveyor system could have undesirable consequences, such as reduced smoothness and possibly uneven running and increased noise.

Aufgabe der Erfindung ist es daher,

  • eine Fahreinrichtung der eingangs genannten Art zu schaffen, mit welcher die erwähnten Nachteile vermieden werden, die aber trotzdem einen ruhigen, ruckfreien Lauf ermöglicht, nicht störungsanfällig ist und eine hohe Lebensdauer hat.
The object of the invention is therefore to
  • to provide a driving device of the type mentioned, with which the mentioned disadvantages are avoided, but still allows a smooth, smooth running, is not prone to failure and has a long life.

Diese Aufgabe wird erfindungsgemäss durch die Merkmale des Anspruchs 1 gelöst.This object is achieved according to the invention by the features of claim 1.

Bevorzugte Weiterbildungen der erfindungsgemässen Fahreinrichtung sind durch die abhängigen Ansprüche definiert.Preferred developments of the driving device according to the invention are defined by the dependent claims.

Die in Fig. 1 dargestellte Fahreinrichtung 1 ist eine Fahrtreppe, die eine untere Ebene E1 mit einer oberen Ebene E2 verbindet. Die Fahreinrichtung 1 weist seitliche Balustraden 2 auf und als sichtbare bewegte Teile die Stufenkette 5 und einen Endloshandlauf 101 auf. Die Stufenkette bzw. Palettenkette 5, im Weiteren als Kette 5 bezeichnet und der Handlauf 101 sind solidarisch bzw. gleichzeitig bewegbar.In the Fig. 1 shown driving device 1 is an escalator, which connects a lower level E1 with an upper level E2. The driving device 1 has lateral balustrades 2 and, as visible moving parts, the step chain 5 and an endless handrail 101. The step chain or pallet chain 5, hereinafter referred to as chain 5 and the handrail 101 are solidary or simultaneously movable.

Die Fahrtreppe bzw. der Endlosförderer umfasst im Wesentlichen eine Vielzahl von Stufen bzw. Tritteinheiten 4 mit der die Stufen 4 verbindenden Stufenkette bzw. Palettenkette 5, einen nicht dargestellten Motor plus Getriebe sowie eine obere Umlenkung 102 und eine untere Umlenkung 103, die sich im oberen bzw. unteren Endbereich der Fahrtreppe befinden, wobei von der oberen Umlenkung 102 der Übersichtlichkeit halber nur die Achse dargestellt ist. Die Paletten oder Stufen bzw. Tritteinheiten 4 sind hier durch Stufen gebildet bzw. dargestellt und weisen Trittflächen 104 auf.The escalator or the endless conveyor essentially comprises a plurality of steps or stepping units 4 with the step chain or pallet chain 5 connecting the steps 4, a motor, not shown, plus gearbox and an upper deflector 102 and a lower deflector 103 located in the upper one or lower end portion of the escalator, of the upper deflection 102 for clarity, only the axis is shown. The pallets or steps or tread units 4 are formed or represented here by steps and have tread surfaces 104.

Wie in Fig. 1 angedeutet, läuft die Förderkette 5 von der unteren Umlenkung 103, die sich im Bereich der unteren Ebene E1 befindet, schräg nach oben zu der dortigen, oberen Umlenkung 102, die sich im Bereich der oberen Ebene E2 befindet. Der Bereich, der von der unteren Umlenkung 103 zur oberen Umlenkung 102 führt, wird im Folgenden auch als Förderbereich 106 der Fahreinrichtung 1 bezeichnet, da in diesem Bereich die Trittflächen 104 der Stufen bzw. Tritteinheiten 4 nach oben weisen und somit Personen aufnehmen können. Die Rückführung der Förderkette 5 von der oberen Umlenkung 102 zur unteren Umlenkung 103 erfolgt in einem Rückführbereich 105, der unterhalb des erwähnten Förderbereiches 106 liegt. Während der Rückführung, das heisst im Rückführbereich 105, weisen die Trittflächen 104 der Tritteinheiten bzw. Stufen 4 nach unten.As in Fig. 1 indicated, the conveyor chain 5 runs from the lower deflection 103, which is located in the region of the lower level E1, obliquely upward to the local upper deflection 102, which is located in the region of the upper level E2. The region which leads from the lower deflection 103 to the upper deflection 102 is also referred to below as the conveying region 106 of the driving device 1, since in this region the tread surfaces 104 of the steps or treading units 4 face upwards and can thus accommodate persons. The return of the conveyor chain 5 from the upper deflection 102 to the lower deflection 103 takes place in a return region 105, which lies below the mentioned conveying region 106. During the return, that is, in the return area 105, have the treads 104 of the treading units or stages 4 down.

Aus dem Stand der Technik bekannte, den Ketten 5 gleichartige Ketten, umfassen eine Vielzahl von Kettengliedern, an denen so genannte Laufrollen in gleichmässigen Abständen befestigt sind.Known from the prior art, the chains 5 similar chains, comprise a plurality of chain links, to which so-called rollers are fixed at regular intervals.

Gemäss einer ersten Ausführungsform der Erfindung, die in Fig. 2 gezeigt ist, kommt nun eine Kette 5 zum Einsatz, die anstatt der Laufrollen so genannte Führungs- bzw. Gleitelemente 6 aufweist. Diese Gleitelemente 6 sind mit der Kette 5 mechanisch verbunden und so ausgeführt, dass sie entlang einer Führungsschiene 7 gleiten bzw. kufen oder surfen. Die Führungsschiene bzw. Schiene 7 und die Kette 5 mit den Gleitelementen 6 sind in Fig. 2 in horizontaler Ausrichtung gezeigt. Die Kette 5 mit den Gleitelementen 6 gleitet mit der gleichen Steigung, wie die Kettenbahn 5 in Fig. 1 von der unteren Ebene E1 zur oberen Ebene E2. Mindestens in einem der Bereiche der Umlenkungen 102 und 103 ist ein Kettenrad 10 mit einem Umfangsbereich 3 vorgesehen, der an seinem äusseren Umfang Ausnehmungen 3.1 aufweist, um die Gleitelemente 6 der Kette 5 mindestens teilweise aufzunehmen. Dieses Kettenrad 10 nach der ersten Ausführungsform ist sehr ähnlich ausgeführt wie das im Zusammenhang mit der zweiten Ausführungsform beschriebene und in Fig. 4A dargestellte Kettenrad 10.According to a first embodiment of the invention, which in Fig. 2 is shown, now comes a chain 5 is used, which has instead of the rollers so-called guide or sliding elements 6. These sliding elements 6 are mechanically connected to the chain 5 and designed so that they slide along a guide rail 7 or skate or surf. The guide rail or rail 7 and the chain 5 with the sliding elements 6 are in Fig. 2 shown in horizontal orientation. The chain 5 with the sliding elements 6 slides with the same pitch as the chain track 5 in Fig. 1 from the lower level E1 to the upper level E2. At least in one of the areas of the deflections 102 and 103, a sprocket 10 is provided with a peripheral portion 3 having recesses 3.1 at its outer periphery to at least partially receive the sliding elements 6 of the chain 5. This sprocket 10 according to the first embodiment is designed very similar to that described in connection with the second embodiment and in Fig. 4A illustrated sprocket 10.

Eine zweite Ausführungsform der Erfindung wird im Folgenden unter Bezugnahme auf die Figuren 3, 4A und 4B beschrieben, wobei für gleiche oder gleichwirkende Elemente aller Ausführungsformen gleiche Bezugszeichen verwendet werden. In Fig. 3 sind Trittelemente bzw. Stufen 4 mit Trittflächen 104, deren Abmessung in Förderrichtung Buchstabe C beträgt bzw. misst, gezeigt. Ferner ist ein Abschnitt der Förderkette 5 gezeigt, die mehrere gleichmässig beabstandete Führungs- bzw. Gleitelemente sowie Laufrollen 9 aufweist, die im Förderbereich der Fahreinrichtung 1 entlang der Führungsschiene 7 geleitet bzw. gegleitet werden. Wie in Fig. 3 zu erkennen ist, kommen hierbei zwei Arten von Elementen 6 und 9 zum Einsatz. Einerseits werden als Laufrollen 9 bezeichnete Elemente verwendet, wie aus dem Stand der Technik bekannt. Anders als beim Stand der Technik, ist der Abstand A zwischen zwei benachbarten Laufrollen 9 deutlich grösser als bei konventionellen Lösungen. Zwischen benachbarten Laufrollen 9 ist mindestens ein als Gleitelement 6 ausgebildetes Element an der Kette 5 angeordnet, vorzugsweise sind aber zwei solche Gleitelemente 6 an der Kette 5 angeordnet.A second embodiment of the invention will be described below with reference to FIGS Figures 3 . 4A and 4B described, wherein the same reference numerals are used for the same or equivalent elements of all embodiments. In Fig. 3 are tread elements or steps 4 with tread surfaces 104, the dimension in the conveying direction letter C measures or measures shown. Further, a portion of the conveyor chain 5 is shown, which has a plurality of uniformly spaced guide or sliding elements and rollers 9, which in the conveying region of Driving device 1 along the guide rail 7 passed or slid. As in Fig. 3 can be seen, come here two types of elements 6 and 9 are used. On the one hand, elements designated as rollers 9 are used, as known from the prior art. Unlike the prior art, the distance A between two adjacent rollers 9 is significantly larger than in conventional solutions. Between adjacent rollers 9, at least one element designed as a sliding element 6 is arranged on the chain 5, but preferably two such sliding elements 6 are arranged on the chain 5.

Aus Fig. 4B kann man entnehmen, dass die Laufrollen 9 ebenso Achsen 9.1 und die Gleitelemente 6 andere Achsen 6.1 aufweisen. Diese Achsen bzw. Kettenbolzen 9.1 und 6.1 verlaufen im Wesentlichen parallel zueinander und stehen auf der Zeichenebene senkrecht. Die Laufrollen 9 und die Gleitelemente 6 werden mechanisch so an der Förderkette 5 angeordnet, dass Gleitzonen 6.2 der Gleitelemente 6 in einer Tangentialebene 7.1 der Laufrollen 9 liegen. Somit rollen also die Laufrollen 9 entlang der Führungsschiene 7, während die Gleitelemente 6 mit ihren Gleitzonen 6.2 entlang der Führungsschiene 7 kufen respektive gleiten.Out Fig. 4B it can be seen that the rollers 9 as well as axes 9.1 and the sliding elements 6 have other axes 6.1. These axes or chain pins 9.1 and 6.1 are substantially parallel to each other and are perpendicular to the plane of the drawing. The rollers 9 and the sliding elements 6 are mechanically arranged on the conveyor chain 5 so that sliding zones 6.2 of the sliding elements 6 lie in a tangential plane 7.1 of the rollers 9. Thus, therefore, the rollers 9 roll along the guide rail 7, while the sliding elements 6 with their sliding zones 6.2 skid along the guide rail 7 respectively slide.

In Fig. 4A sind weitere Details des Fördersystems bzw. Antriebssystems 100 zu erkennen. Auch der in Fig. 4A gezeigte Teil des Fördersystems 100 ist aufrissmässig dargestellt, sowie im eingebauten Zustand in einer Fahrtreppe. Bei einem Fahrsteig oder Palettenförderer verlaufen die gezeigten Elemente des Förder- bzw. Antriebssystems 100 im Wesentlichen annähernd horizontal bis leicht schräg. Die gezeigte Kette 5 umfasst mehrere Kettenelemente, respektive Kettenglieder 8. Diese Kettenglieder 8 sind jeweils gelenkig aneinander befestigt und bilden eine Endloskette. Die Kettenglieder 8 erstrecken sich in der gezeigten Ausführungsform jeweils von Achse bzw. Kettenbolzen zu Achse bzw. Kettenbolzen, d.h. zwischen zwei Achsen bzw. Kettenbolzen 9.1 und 6.1 einer Laufrolle 9 und des benachbarten Gleitelementes 6 oder zwischen zwei Achsen bzw. Kettenbolzen 6.1 benachbarter Gleitelemente 6. Der Abstand zwischen einer der Achsen bzw. Kettenbolzen 9.1 zur nächstgelegenen Achse 6.1 bzw. der Abstand zwischen zwei aufeinanderfolgenden Achsen bzw. Kettenbolzen 6.1 bestimmt die Länge der Kettenglieder 8. Da im gezeigten Beispiel aufeinanderfolgende Achsen äquidistant mit einem Achsabstand A/3 sind, haben alle Kettenglieder 8 die gleiche Länge. Dies vereinfacht den Aufbau der gesamten Förderkette 5 wesentlich, da nur ein oder zwei Typen von Kettengliedern 8 gebraucht werden.In Fig. 4A Further details of the conveyor system or drive system 100 can be seen. Also the in Fig. 4A shown part of the conveyor system 100 is shown in Aufrissmässig, and when installed in an escalator. In the case of a moving walk or pallet conveyor, the elements of the conveying or drive system 100 shown are substantially approximately horizontal to slightly inclined. The chain 5 shown comprises a plurality of chain elements, or chain links 8. These chain links 8 are each hinged together and form an endless chain. The chain links 8 extend in the embodiment shown in each case from axle or chain pin to axle or chain pin, ie between two Axles or chain pins 9.1 and 6.1 of a roller 9 and the adjacent sliding element 6 or between two axes or chain pins 6.1 adjacent sliding elements 6. The distance between one of the axes or chain pins 9.1 to the nearest axis 6.1 or the distance between two consecutive axes or Chain pin 6.1 determines the length of the chain links 8. Since in the example shown successive axes are equidistant with a center distance A / 3, all chain links 8 have the same length. This greatly simplifies the construction of the entire conveyor chain 5, since only one or two types of chain links 8 are needed.

Vorzugsweise entspricht der Achsabstand A zwischen zwei benachbarten Laufrollen 9 ungefähr, etwa der Länge C des Trittelements respektive der Tritteinheit bzw. Stufe 4, d.h. A ist ungefähr gleich C, wie aus Fig. 3 ersichtlich. Pro Tritteinheit bzw. Stufe 4 ist eine Laufrolle 9 vorgesehen, und vorzugsweise ist die Tritteinheit bzw. Stufe 4 im Bereich der Kettenbolzen bzw. Achse 9.1 mit der Laufrolle 9 und somit auch mit der Förderkette 5 mechanisch verbunden, wie in Fig. 3 gezeigt.Preferably, the axial distance A between two adjacent rollers 9 corresponds approximately to about the length C of the Trittelements respectively the stepping unit or stage 4, ie A is approximately equal to C, as from Fig. 3 seen. Per step unit or stage 4, a roller 9 is provided, and preferably the stepping unit or step 4 in the region of the chain pin or axle 9.1 with the roller 9 and thus also mechanically connected to the conveyor chain 5, as in Fig. 3 shown.

In Fig. 4A ist auch gezeigt wie die Förderkette 5 um das Kettenrad 10 herum geführt wird, um die Richtung der Förderkette 5 zu ändern. Am äusseren Umfang des Kettenrades 10 sind die Ausnehmungen 3.1 für die Laufrollen 9 und Ausnehmungen 3.2 für die Gleitelemente 6 vorgesehen. Da zwischen zwei Laufrollen 9 jeweils zwei Gleitelemente 6 angeordnet sind, wie bei der als Variante oder zum Beispiel dargestellten Ausführungsform, sind am Kettenrad 10 zwischen zwei Ausnehmungen 3.1 für Laufrollen 9 zwei entsprechende Ausnehmungen 3.2 für die Gleitelemente 6 vorgesehen. Die Zahl der Ausnehmungen 3.2 zwischen zwei Ausnehmungen 3.1 kann beliebig sein.In Fig. 4A It is also shown how the conveyor chain 5 is guided around the sprocket 10 to change the direction of the conveyor chain 5. At the outer periphery of the sprocket 10, the recesses 3.1 are provided for the rollers 9 and recesses 3.2 for the sliding elements 6. Since between two rollers 9 two sliding elements 6 are arranged, as in the embodiment shown as a variant or for example, two corresponding recesses 3.2 for the sliding elements 6 are provided on the sprocket 10 between two recesses 3.1 for rollers 9. The number of recesses 3.2 between two recesses 3.1 can be arbitrary.

In einer anderen, nicht gezeigten Ausführungsform weist das Kettenrad 10 in gleichen Winkelabständen angeordnete Ausnehmungen auf, die alle gleich oder gleichgross oder ähnlich ausgeführt sind. Diese Ausnehmungen nehmen dann sowohl die Laufrollen 9 als auch die Gleitelemente 6 auf.In another, not shown embodiment, the sprocket 10 at equal angular intervals arranged recesses, which are all the same or the same size or similar executed. These recesses then take on both the rollers 9 and the sliding elements 6.

In den Figuren 5A und 5B sind weitere Details einer möglichen Ausführungsform eines Gleitelements 6 gezeigt. Fig. 5A zeigt eine Aufrissansicht bzw. Frontansicht und Fig. 5B einen Schnitt längs der Linie Z-Z der Fig. 5A. Das gezeigte Gleitelement 6 hat eine Gleitzone 6.2, die zum optimalen Gleiten ausgelegt ist. Im gezeigten Beispiel ist die Gleitzone 6.2 kufenförmig ausgelegt, um eine problemlose Einführung bzw. eine Gleitung in die Führungsschiene 7 zu ermöglichen. Neben der Gleitzone 6.2 umfasst das Gleitelement 6 einen Tragkörper oder Gründkörper 6.3, zum Beispiel mit Verstrebungen oder Stegen. Zusätzlich kann auch ein Bereich zur Aufnahme einer Einsatzbuchse 6.4 oder einer Gleitlagerbuchse bei einer neuen Variante des Gleitelementes 6 vorgesehen werden.In the FIGS. 5A and 5B Further details of a possible embodiment of a sliding element 6 are shown. Fig. 5A shows an elevation view and front view and Fig. 5B a section along the line ZZ the Fig. 5A , The sliding element 6 shown has a sliding zone 6.2, which is designed for optimum sliding. In the example shown, the sliding zone 6.2 is designed skid-shaped in order to allow a smooth introduction or a slide into the guide rail 7. In addition to the sliding zone 6.2, the sliding element 6 comprises a support body or base body 6.3, for example with struts or webs. In addition, an area for receiving an insert bushing 6.4 or a plain bearing bush in a new variant of the sliding element 6 can also be provided.

Vorzugsweise ist die Gleitzone 6.2 mit einem Material beschichtet, oder die Gleitzone 6.2 umfasst ein Material, das einen niedrigen Reibungskoeffizienten hat. Besonders geeignet ist eine Gleitzone 6.2 mit einer PTFE-Bandage (PTFE: Polytetrafluorethylen) oder mit einer Polyurethan-Bandage. Es kann auch ein Aramid verwendet werden, bzw. Thermoplastische Elastomere (TPE) oder thermoplastische Polyurethane (TPU) sowie alle Thermoplastischen Kunststoffe. Diese Bandagen sind vorzugsweise hydrolysefest oder hydrolysestabilisiert ausgeführt.Preferably, the sliding zone 6.2 is coated with a material, or the sliding zone 6.2 comprises a material that has a low coefficient of friction. Particularly suitable is a sliding zone 6.2 with a PTFE bandage (PTFE: polytetrafluoroethylene) or with a polyurethane bandage. It is also possible to use an aramid or thermoplastic elastomers (TPE) or thermoplastic polyurethanes (TPU) as well as all thermoplastics. These bandages are preferably carried out hydrolysis or hydrolysis stabilized.

PTFE eignet sich besonders wegen des bei geeigneten Materialkombinationen niedrigen Reibungskoeffizienten und der Robustheit. Da PTFE besonders reibungslos gleitet auch auf PTFE, kommt in einer bevorzugten Ausführungsform eine Führungsschiene 7 zum Einsatz, die im Bereich der Gleitzone auch mit PTFE versehen ist, bzw. mit Teflon beschichtet ist. Außerdem ist die Haftreibung von PTFE bei geeigneten Werkstoffkombinationen genau gleich wie die Gleitreibung, so dass der Übergang vom Stillstand zur Bewegung ohne Rucken stattfindet, was für Anwendungen im Bereich der Fahreinrichtungen besonders von Vorteil ist.PTFE is particularly suitable because of the low friction coefficient and the robustness of suitable material combinations. Since PTFE slides particularly smoothly on PTFE, in a preferred embodiment, a guide rail 7 is used, which is also provided in the region of the sliding zone with PTFE, or coated with Teflon. In addition, the friction of PTFE with suitable material combinations is exactly the same as the sliding friction, so that the transition from standstill to motion takes place without jerking, which is particularly advantageous for applications in the field of driving equipment.

In den Figuren 6A und 6B sind weitere Details einer möglichen Ausführungsform bzw. Kettenvariante beschrieben. Es handelt sich wiederum um eine Kettenvariante, bei der Laufrollen 9 und Gleitelemente 6 an ein und derselben Kette 5 zum Einsatz kommen. Wie in Fig. 1 angedeutet, gibt es Übergangsbereiche, wo ein Übergangsbogen 4.1 oder 4.2 mit einem Übergangsradius vorhanden ist. Dies ist speziell der Fall, wenn bei einer Fahreinrichtung 1 ein Übergang zwischen zwei unterschiedlich geneigten Teilen des Förderbereichs vorgesehen ist. Durch die Vorspannung auf der Förderkette 5 verläuft im Bereich des Übergangsbogens 4.1 die Kette 5 wie eine Sehne des Kreises, dessen Radius dem Übergangsradius entspricht. Um hier ein Abheben der Laufrollen 9 und/oder der Gleitelemente 6 zu verhindern, wird gemäss Erfindung eine Kettengegendruckführung 14 vorgesehen. Wie in Fig. 6A und Fig. 6B zu erkennen, hat die Kettengegendruckführung 14 einen Querschnitt in Form eines U oder C. Die Kettengegendruckführung 14 ist so installiert, dass sie gegen zwei Laschen der Kettenglieder 8 drückt, um so die Laufrolle 9 oder das Gleitelement 6 gegen die Führungsschiene 7 zu drücken. Die Kettengegendruckführung 14 verhindert, dass die Förderkette 5 in Form der beschriebenen Sehne verläuft.In the Figures 6A and 6B Further details of a possible embodiment or chain variant are described. Again, this is a chain variant in which rollers 9 and sliding elements 6 are used on one and the same chain 5. As in Fig. 1 indicated there are transition areas where a transition arc 4.1 or 4.2 is present with a transition radius. This is the case in particular if a transition between two differently inclined parts of the conveying region is provided in a driving device 1. Due to the bias on the conveyor chain 5 runs in the region of the transition arc 4.1, the chain 5 as a chord of the circle whose radius corresponds to the transition radius. In order to prevent lifting of the rollers 9 and / or the sliding elements 6, a chain back pressure guide 14 is provided according to the invention. As in FIGS. 6A and 6B The chain back pressure guide 14 has a cross section in the form of a U or C. The chain back pressure guide 14 is installed so that it presses against two lugs of the chain links 8, so as to press the roller 9 or the sliding member 6 against the guide rail 7. The chain back pressure guide 14 prevents the conveyor chain 5 runs in the form of the described tendon.

Alternativ oder zusätzlich kann auch eine weitere Kettengegendruckführung 15, 16, 17 eingesetzt werden, wie sie in den Figuren 6C und 6D gezeigt ist. Es kommen in diesem Fall durch eine Feder 16 beaufschlagte Druckführungselemente 15 zum Einsatz, die gegen die Laufrollen 9 oder Gleitelemente 6 drücken. Durch die Feder 16 bedingt, ergibt sich eine automatische Anpassung der Position bzw. Höhe der Druckführungselemente. In Fig. 6C ist das Druckführungselement weiter Richtung Führungsschiene 7 verlagert als in Fig. 6D.Alternatively or additionally, a further chain back pressure guide 15, 16, 17 are used, as in the Figures 6C and 6D is shown. It come in this case by a spring 16 acted upon pressure guide elements 15 are used, which press against the rollers 9 or 6 sliding elements. Conditioned by the spring 16, there is a automatic adjustment of the position or height of the pressure guide elements. In Fig. 6C the pressure guide element is further displaced towards the guide rail 7 as in Fig. 6D ,

Statt zwischen zwei aufeinanderfolgenden Laufrollen drei Kettenglieder 8 anzuordnen, wie oben beschrieben, kann auch eine kleinere oder grössere Anzahl von Kettenteilungen bzw. Kettengliedern eingesetzt werden. Je längere Kettenglieder, um so notwendiger wird der Einsatz einer geeigneten Kettengegendruckführung, wie beschrieben, da Ketten mit längeren Kettengliedern weniger gelenkig und flexibel sind.Instead of arranging three chain links 8 between two successive rollers, as described above, a smaller or larger number of chain pitches or chain links can also be used. The longer chain links, the more necessary the use of a suitable chain back pressure guide, as described, since chains with longer chain links are less articulated and flexible.

In einer bewerten Ausführungsform sind die Gleitelemente 6 über entsprechende Buchsen mechanisch so mit der Förderkette 5 verbunden, dass sie gewisse Schwankungen, Kettenschwingungen oder Pendelbewegungen um die Achse 6.1 und/oder in Querrichtung zulassen.In an evaluation embodiment, the sliding elements 6 are mechanically connected to the conveyor chain 5 via corresponding bushes in such a way that they permit certain fluctuations, chain oscillations or pendulum movements about the axis 6.1 and / or in the transverse direction.

Mit der vorliegenden Erfindung lässt sich eine komplett neue Fahr- oder Rolltreppengeneration realisieren, die ganz oder wenigstens teilweise ohne Laufrollen auskommt. Die neue Fahreinrichtung ist vorteilhafter, nutzbringender und günstiger, da anstatt bisher drei Laufrollen 9 pro Stufe 4 oder Palette jetzt nur noch eine Laufrolle, wie bei der Ausführungsform nach Fig. 3, oder überhaupt keine Laufrollen, wie bei der Ausführungsform nach Fig. 2, zum Einsatz kommen. Dies hat den Vorteil, dass man teure Kugellager einspart, die zum Verbinden der Laufrollen 9 an der Förderkette 5 erforderlich sind.With the present invention, a completely new driving or escalator generation can be realized, which manages completely or at least partially without rollers. The new driving device is more advantageous, beneficial and cheaper, since instead of the previous three rollers 9 per level 4 or pallet now only a roller, as in the embodiment according to Fig. 3 , or no rollers at all, as in the embodiment according to Fig. 2 , are used. This has the advantage that you save expensive ball bearings, which are required for connecting the rollers 9 on the conveyor chain 5.

Bei Verwendung von mehreren Gleitelementen 6 ist eine gleichmässigere Nutz- und Lastverteilung gegeben. Dadurch wird eine kleinere Abnützung gewährleistet bzw. festgelegt bzw. festgesetzt.When using a plurality of sliding elements 6 a more uniform load and load distribution is given. As a result, a smaller wear is guaranteed or set or fixed.

Wie beschrieben, lässt sich die Erfindung sowohl auf Fahrtreppen als auch auf Fahrsteige anwenden.As described, the invention can be applied to both escalators and moving walks.
