Description

Die Erfindung betrifft eine Fahrtreppe mit einer Endlos-Formation von aufeinanderfolgenden Stufen gemäss Anspruch 1.The invention relates to an escalator with an endless formation of successive stages according to claim 1.

Fahrtreppen, häufig auch als Rolltreppen bezeichnet, weisen eine Endlosekette von aufeinanderfolgenden Stufen auf, die Personen oder Gepäckstücke auf- bzw. abwärts befördern können. An den Stufen sind seitwärts gerichtete Rollen vorhanden, die auf Laufschienen laufen. Durch Führungsschienen werden die Stufen in die gewünschte Lage gebracht. Ausserdem dienen die Rollen samt Führungsschienen dazu, um vertikal gerichtete Kräfte, zum Beispiel beim Betreten einer Stufe, abzufangen.Escalators, often referred to as escalators, have an endless chain of successive steps that can carry people or luggage up or down. There are sideways rollers on the steps that run on rails. Guide rails move the steps to the desired position. In addition, the rollers and guide rails serve to intercept vertically directed forces, for example when entering a step.

Um das Kippen einer einzelnen Stufe zu verhindern, wenn diese zum Beispiel exzentrisch belastet wird, weisen Fahrtreppen typischerweise Notführungssysteme auf. Die Notführungssysteme benötigen verschiedene Teile, die hergestellt und befestigt werden müssen. Ausserdem ist die Herstellung der Notführung relativ aufwendig.To prevent tilting a single step, for example, when it is eccentrically loaded, escalators typically include emergency guidance systems. The emergency guidance systems require various parts that must be manufactured and fastened. In addition, the production of emergency management is relatively expensive.

Die Aufgabe der Erfindung wird darin gesehen, zur Vermeidung der Nachteile des Standes der Technik eine neuartige Fahrtreppe vorzuschlagen, die ohne die bisher erforderlichen Notführungssysteme auskommt. Es soll vor allem der Montageaufwand und Zusammenbauaufwand reduziert werden.The object of the invention is seen to propose a novel escalator to avoid the disadvantages of the prior art, which manages without the emergency management systems previously required. It should be reduced especially the assembly effort and assembly costs.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäss durch die Merkmale des kennzeichnenden Teils des Anspruchs 1.The solution of this object is achieved according to the invention by the features of the characterizing part of claim 1.

Gemäss Erfindung wird an jeder Stufe ein Notführungshaken so im Bereich der Frontfläche bzw. der Setzstufe angebracht, dass der Notführungshaken einer höher liegenden Stufe sich gegen einen Teil einer Wange der nächsten unterhalb liegenden Stufe abstützt, falls die Stufe im Bereich der Trittfläche exzentrisch belastet wird. Mit anderen Worten ausgedrückt wird jede Stufe mit einem Notführungshaken versehen, der so angeordnet ist, dass die Stufe sich gegeneinander abstützen falls es zu eine aussermittigen Belastung kommt.According to the invention, at each step, an emergency guide hook is mounted in the area of the front surface or riser such that the emergency guide hook of a higher level supports itself against a part of a cheek of the next underlying step if the step is eccentrically loaded in the area of the tread. In other words, each step is provided with an emergency guide hook, which is arranged so that the step support each other if there is an eccentric load.

Es ist ein Vorteil dieser Erfindung, dass die Montage sehr viel einfacher ist, da der Notführungshaken bereits an der Stufe vormontiert werden kann. Es bedarf also keiner aufwendigen Montage und Zusammenbauen der einzelnen Elemente des Notführungssystems, wie bei bisherigen Fahrtreppen. Alternativ können auch die Notführungshaken mit der Stufe mit gegossen werden.It is an advantage of this invention that the mounting is much easier since the emergency guide hook can already be preassembled on the step. So it requires no complex installation and assembly of the individual elements of the emergency guidance system, as in previous escalators. Alternatively, the emergency guide hooks can also be cast with the step.

Ausserdem ist der Notführungshaken an sich günstig herzustellen, vor allem dann, wenn er als Stanzteil aus Blech bereitgestellt wird.In addition, the emergency guide hook is cheap to manufacture, especially if it is provided as a stamped part made of sheet metal.

In einer gegenwärtig bevorzugten Ausführungsform der Erfindung sitzt der Notführungshaken direkt auf der Achse einer der an der Stufe vorhandenen Rollen. Dies vereinfacht die Montage.In a presently preferred embodiment of the invention, the emergency guide hook is seated directly on the axis of one of the rollers present on the step. This simplifies the assembly.

Fig. 1 zeigt eine konventionelle Fahrtreppe 1, die ein unteres Niveau E1 mit einem oberen Niveau E2 verbindet. Die Fahrtreppe weist eine Endlos-Formation von aufeinanderfolgenden Stufen 3 auf, die in Fig. 1 jedoch nur teilweise gezeigt sind. Die Fahrtreppe 1 weist, wie üblich, als seitliche Begrenzungen im unteren Teil Sockelbleche 2.1 (siehe Fig. 3) und im oberen Teil eine ortsfeste Balustrade 2 auf, auf welchen zuoberst im Allgemeinen ein zusammen mit der Endlos-Formation aus Stufen 3 bewegbarer Handlauf 2.2 angeordnet ist. Es sind typischerweise bei derartigen Fahrtreppen 1 Vorlaufschienen 5 und Rücklaufschienen 6 vorgesehen. Fig. 1 shows a conventional escalator 1, which connects a lower level E1 with an upper level E2. The escalator has an endless formation of successive stages 3, which in Fig. 1 but only partially shown are. The escalator 1 has, as usual, as lateral boundaries in the lower part of base plates 2.1 (see Fig. 3 ) and in the upper part of a stationary balustrade 2, on which at the top of a generally movable together with the endless formation of steps 3 handrail 2.2 is arranged. There are typically provided in such escalators 1 feed rails 5 and return rails 6.

Jede Stufe 3 weist eine Trittfläche 3.1, eine Frontfläche bzw. Setzstufe 3.3 und auf jeder Seite eine seitwärts gerichtete Wange 3.4 auf. In Fig. 2 ist eine erfindungsgemässe Stufe 3 gezeigt. Bei dieser Abbildung liegt eine der seitlichen Wangen quasi in der Zeichenebene. Die zweite seitliche Wange 3.4 ist nur von der Stufeninnenseite zu sehen. Im Bereich jeder Wange sind zwei seitwärts nach aussen ragende Rollen 7 und 8 vorgesehen, die entlang der seitlich angebrachten, schräg verlaufenden Schienen 5, 6 der Fahrtreppe 1 geführt und abgestützt werden.Each step 3 has a tread surface 3.1, a front surface or riser 3.3 and on each side of a sideways cheek 3.4. In Fig. 2 a stage 3 according to the invention is shown. In this illustration, one of the lateral cheeks is almost in the plane of the drawing. The second side cheek 3.4 can only be seen from the inside of the steps. In the region of each cheek two laterally outwardly projecting rollers 7 and 8 are provided, which are guided along the laterally mounted, obliquely running rails 5, 6 of the escalator 1 and supported.

Um das Kippen einer einzelnen Stufe 3 zu verhindern, wenn diese zum Beispiel durch eine Belastung der Trittfläche 3.1 exzentrisch belastet wird, weisen konventionelle Fahrtreppen 1 typischerweise zwei Notführungsschienen 9 auf. Die Notführungsmontage ist relativ aufwendig und die Notführung benötigt zahlreiche verschiedene Teile 9, 10, 11, 12, die hergestellt und geliefert werden müssen.In order to prevent the tilting of a single step 3 when it is eccentrically loaded, for example by a load on the tread surface 3.1, conventional escalators 1 typically have two emergency guide rails 9. The emergency guide assembly is relatively expensive and the emergency guide requires many different parts 9, 10, 11, 12, which must be manufactured and delivered.

In Fig. 3 ist ein Schnitt durch eine konventionelle Fahrtreppe 1 quer zur Fahrtrichtung gezeigt. Anhand dieser Figur wird kurz erläutert wie die heute übliche Notführung aufgebaut ist. Ausserdem werden andere Elemente der Fahrtreppe 1 beschrieben, die auch bei einer erfindungsgemässen Fahrtreppe 1 vorhanden sind.In Fig. 3 is a section through a conventional escalator 1 shown transversely to the direction of travel. Based on this figure will be briefly explained how the usual today emergency management is constructed. In addition, other elements of the escalator 1, which are also present in an inventive escalator 1.

Die Fahrtreppe 1 ist in einem Fachwerk gelagert, dessen verschiedene Elemente in Fig. 3 mit dem Bezugszeichen 4 gekennzeichnet sind. An diesem Fachwerk 4 sind die eingangs genannten Vorlaufschienen 5 und Rücklaufschienen 6 befestigt. In Fig. 3 ist zu erkennen, dass die Vorlaufschienen 5 im Querschnitt eine L-Form haben und dadurch zwei verschiedene Laufebenen definieren. Auf der oberen Laufebene laufen die äusseren Rollen 7, d.h. die Rollen 7 mit grossem Radabstand, und auf den unteren Laufebenen laufen die inneren Rollen 8, d.h. die Rollen 8 mit kleinem Radabstand. Die Rollen 7 und 8 sind in Fig. 3 schwarz dargestellt, um sie besser hervor zu heben. Die Vorlaufschienen 5 dienen als vertikales Auflager für die Stufen 3 und nehmen einerseits vertikal gerichtete Kräfte auf und führen andererseits die Stufen 3 am Fachwerk 4 auf- oder abwärts (je nach Bewegungsrichtung). Der vertikale Abstand zwischen der oberen Laufebene und der unteren Laufebene ist im schrägen Bereich der Fahrtreppe 1 relativ klein gewählt so dass die Stufen 3 in die Normalposition gedreht bzw. geschwenkt und stabil geführt werden. In der Normalposition ist der vertikale Achsabstand VA1 zwischen den äusseren Rollen 7 und den inneren Rollen 8 klein, wie auf der linken Seite von Fig. 3 angedeutet.The escalator 1 is stored in a truss whose various elements in Fig. 3 marked with the reference numeral 4. At this truss 4, the aforementioned feed rails 5 and return rails 6 are attached. In Fig. 3 it can be seen that the feed rails 5 have an L-shape in cross-section and thereby define two different levels of running. On the upper run level run the outer rollers 7, ie the rollers 7 with a large wheelbase, and run on the lower levels run the inner rollers 8, ie the rollers 8 with a small wheelbase. The rollers 7 and 8 are in Fig. 3 shown in black to make it stand out better. The feed rails 5 serve as a vertical support for the steps 3 and take on the one hand vertically directed forces and on the other hand lead the steps 3 on the framework 4 up or down (depending on the direction of movement). The vertical distance between the upper running plane and the lower running plane is chosen to be relatively small in the inclined area of the escalator 1 so that the steps 3 are rotated or pivoted to the normal position and guided stably. In the normal position, the vertical center distance VA1 between the outer rollers 7 and the inner rollers 8 is small as on the left side of FIG Fig. 3 indicated.

Die Rollen 7, 8 auf jeder Seite einer Stufe 3 sind jeweils gegeneinander versetzt angeordnet, um die Stufen 3 stabil entlang der schräg verlaufenden Schienen 5, 6 führen zu können.The rollers 7, 8 on each side of a stage 3 are each offset from one another, in order to guide the steps 3 stably along the inclined rails 5, 6 can.

Die Rücklaufschienen 6 weisen auch eine obere Laufebene 6.1 und eine untere Laufebene 6.2 auf. Der Abstand dieser Laufebenen 6.1 und 6.2 ist sehr viel grösser und die Stufen 3 werden in dem sogenannten Rücklaufbereich (siehe Fig. 1) hängend, d.h. mit der Trittfläche 3.1 nach unten weisend, zurückgefördert. Der vertikale Achsabstand VA2 zwischen den äusseren Rollen 7 und den inneren Rollen 8 ist im Rücklaufbereich sehr viel grösser als der vertikale Achsabstand VA1 im Vorlauf, wie auf der rechten Seite von Fig. 3 angedeutet.The return rails 6 also have an upper run level 6.1 and a lower run level 6.2. The distance between these run levels 6.1 and 6.2 is much greater and the levels 3 are in the so-called return area (see Fig. 1 ), ie, with the tread surface 3.1 facing down, conveyed back. The vertical center distance VA2 between the outer rollers 7 and the inner rollers 8 is in the return area much larger than the vertical center distance VA1 in the flow, as on the right side of Fig. 3 indicated.

Die bisher im Zusammenhang mit Fig. 3 beschriebenen Elemente sind auch bei einer gegenwärtig bevorzugten Ausführungsform der Erfindung vorhanden.The previously related to Fig. 3 The elements described are also present in a presently preferred embodiment of the invention.

Nun werden kurz die Elemente der heute übliche Notführung beschrieben. Es sind zwei Notführungsschienen 9 vorhanden, die mit Befestigungswinkeln 11 und dazugehörenden Befestigungsschrauben 12, Befestigungsmuttern und Schraubensicherungen am Fachwerk 4 montiert sind. Im Bereich der Rollen 8 ist ein Haken 10 am Stufenkörper 3 bzw. am Stufenholm 3.2 befestigt. Dieser Haken 10 weist von den seitlichen Wangen der Stufe 3 aus betrachtet nach innen. Im montierten Zustand greifen die Haken 10 unter die Notführungsschienen 9 und laufen dort im Normalfall berührungslos. Falls es zu einer exzentrischen Belastung einer Stufe 3 kommt, so kippt diese Stufe 3 leicht um eine horizontale Achse bzw. Stufenachse und die Haken berühren auf einer oder auf beiden Seiten die Notführungsschienen 9. Dadurch werden vertikal aufwärts gerichtete Kippbewegungen gestoppt. Es kommt in diesem Bereich zu störenden Reibungen bzw. zum Anlehnen und Abstützen, da der Haken 10 entlang der Notführungsschiene 9 rutscht. Das führt zu Reibungen und unter Umständen zu Geräuschen, die unerwünscht sind.Now the elements of today's emergency management are briefly described. There are two emergency guide rails 9 available, which are mounted with mounting brackets 11 and associated mounting screws 12, fastening nuts and screw locks on truss 4. In the area of the rollers 8, a hook 10 is fastened to the step body 3 or to the step rail 3.2. This hook 10 has, viewed from the side cheeks of level 3 from inside. In the assembled state, the hooks 10 engage under the emergency guide rails 9 and run normally there without contact. If there is an eccentric load of a level 3, this level 3 tilts slightly about a horizontal axis or step axis and the hook touch on one or both sides of the Notführungsschienen 9. This vertical upwards tilting movements are stopped. It comes in this area to disturbing friction or for leaning and supporting, since the hook 10 along the emergency guide rail. 9 slips. This leads to friction and possibly to noises that are undesirable.

Anhand von Fig. 2 werden nun die erfindungswesentlichen Elemente erläutert, soweit diese nicht bereits beschrieben wurden.Based on Fig. 2 Now, the elements essential to the invention are explained, as far as they have not already been described.

Jede Stufe 3 weist einen Stufenkörper bzw. Stufenkorpus auf, der dazu ausgelegt ist der Stufe 3 Stabilität zu verleihen und verschiedenen Elemente trägt oder miteinander verbindet. Mit dem Stufenkörper verbunden sind die Trittfläche 3.1 und die Frontfläche bzw. Setzstufe 3.3. In der gezeigten Ausführungsform der Erfindung umfasst der Stufenkörper zwei seitliche Wangen 3.4, die durch eine Art offenen Rahmen gebildet werden. Der offene Rahmen weist im unteren Bereich einen länglichen Stufenholm 3.2 auf. Ausgehend vom Stufenholm 3.2 verlaufen in der gezeigten Darstellung seitliche Wangen 3.4 und hintere Streben 3.5 nach oben. Diese Wangen 3.4 und Streben 3.5 wiederum sind mit Holmen 3.6 verbunden auf denen die Trittfläche 3.1 ruht. Im hinteren Bereich des Stufkörpers werden die beiden Wangen durch die Radachse oder eine Stufenachse 7.1 verbunden. Im vorderen Bereich des Stufenkörpers verläuft die Frontfläche bzw. Setzstufe 3.3 zwischen den Wangen 3.4. Der Stufenholm erstreckt sich im Wesentlichen parallel zu einer durch die schräg verlaufenden Laufschienen (5) vorgegebene Richtung, wenn sich die entsprechende Stufe (3) in einem Vorlaufbereich der Fahrtreppe (1) befindet. Die Abweichung kann ± 10 Grad betragen.Each stage 3 has a step body or step body designed to give stability to stage 3 and carry or connect various elements. Connected to the step body are the tread surface 3.1 and the front surface or riser 3.3. In the illustrated embodiment of the invention, the step body comprises two lateral cheeks 3.4, which are formed by a kind of open frame. The open frame has an elongated step spar 3.2 in the lower area. Starting from the step rail 3.2 extend in the illustration shown side cheeks 3.4 and 3.5 rear struts upwards. These cheeks 3.4 and struts 3.5 in turn are connected to spars 3.6 on which the tread surface 3.1 rests. In the rear region of the step body, the two cheeks are connected by the wheel axle or a stepped axle 7.1. In the front region of the step body, the front surface or riser 3.3 runs between the cheeks 3.4. The step rail extends substantially parallel to a predetermined by the inclined rails (5) direction when the corresponding stage (3) is located in a lead-in area of the escalator (1). The deviation can be ± 10 degrees.

Gemäss Erfindung ist nun mindestens im Bereich einer der Wangen ein Notführungshaken 13 angebracht, der im gezeigten Beispiel im Wesentlichen senkrecht zur Wange definierten Ebene nach innen ragt. Wird nun die Stufe 3 exzentrisch belastet (wie durch den Pfeil F angedeutet), so ergibt sich eine Kippbewegung der Stufe 3, die durch den Drehpfeil D dargestellt ist. Der Notführungshaken 13 bewegt sich in diesem Fall etwas nach oben und vorne, wie durch den Pfeil A schematisch angezeigt wird.According to the invention, an emergency guide hook 13 is now mounted at least in the region of one of the cheeks, which is shown in FIG Example substantially perpendicular to the cheek defined plane protrudes inward. If the stage 3 is now eccentrically loaded (as indicated by the arrow F), the result is a tilting movement of the stage 3, which is represented by the rotary arrow D. The emergency guide hook 13 moves in this case slightly up and forward, as indicated schematically by the arrow A.

Betrachtet man nun die Endlos-Formation von aufeinanderfolgenden Stufen 3, dann ist zu erkennen, dass der Notführungshaken 13 im "Notfall" das rückwärtige Ende des Stufenholms 3.2 der nächsten Stufe 3 berührt, die sich etwas unterhalb der exzentrisch belasteten ersten Stufe 3 befindet. In Fig. 2 ist an der Stufe 3 der Bereich 14 durch einen Kreis gekennzeichnet in dem es zu einer Berührung kommen würde, wenn der Notführungshaken 13 einer nicht gezeigten, oberen ersten Stufe 3 zum Einsatz käme.Considering now the endless formation of successive stages 3, it can be seen that the emergency guide hook 13 in the "emergency" touches the rear end of the stage strut 3.2 of the next stage 3, which is slightly below the eccentrically loaded first stage 3. In Fig. 2 At level 3, area 14 is indicated by a circle in which it would come into contact when emergency guide hook 13 of an upper first stage 3, not shown, would be used.

In Fig. 4 sind Details einer weiteren erfindungsgemässen Ausführungsform in einer schematischen Seitenansicht gezeigt. In dieser Figur 4 ist die schräg verlaufende Vorlaufschienen 5 gezeigt und es sind zwei aufeinanderfolgende Stufen 3 zu erkennen. Die Rollen 7 laufen auf oberen Laufebenen in der Laufschiene 5, wie beschrieben. Es werden die gleichen Bezugszeichen verwendet wie in den bisherigen Figuren. Eine Erläuterung der bereits beschriebenen Elemente erübrigt sich daher.In Fig. 4 Details of a further embodiment according to the invention are shown in a schematic side view. In this FIG. 4 the obliquely running rails 5 are shown and there are two successive stages 3 can be seen. The rollers 7 run on upper run levels in the track 5, as described. The same reference numerals are used as in the previous figures. An explanation of the elements already described is therefore unnecessary.

In Fig. 4 ist eine spezielle Ausgestaltung des Notführungshakens 13 zu erkennen. Der Notführungshaken 13 sitzt in der Verlängerung der Achse der Rolle 8 und ist innen angeordnet und nach aussen gerichtet (von der Wange aus betrachtet).In Fig. 4 a special embodiment of the emergency guide hook 13 can be seen. The emergency guide hook 13 is located in the extension of the axis of the roller 8 and is arranged inside and directed outwards (viewed from the cheek).

Auf der Innenseite der Wange, respektive des Stufenholms 3.2 ist der Notführungshaken 13 mit einer Mutter 15 und einer optionalen Schraubensicherung auf der Mittelachse der Rolle 8 befestigt. Details hierzu sind der Fig. 5 zu entnehmen. Bei dieser Figur handelt es sich um eine vergrösserte Draufsicht des Bereichs zwischen zwei aufeinanderfolgenden Stufen 3. Fig. 5 zeigt, dass der Notführungshaken 13 zum Beispiel ein aus Blech gestanztes und gebogenes Teil sein kann, das mit einer Vertikalfläche gegen den Stufenholm 3.2 anliegt. Diese Vertikalfläche weist ein Loch oder einen Schlitz auf, um den Notführungshaken 13 mit der Achse der Rolle 8 verschrauben bzw. befestigen zu können. Weiterhin weist der Notführungshaken 13 einen Kontaktbereich auf, der dazu ausgelegt ist mit dem Stufenkörper oder Stufenholm 3.2 der nächsten Stufe 3 bei exzentrischer Belastung in Wechselwirkung zu treten. Dieser Kontaktbereich kann, wie in Fig. 5 gezeigt, einen Flächenbereich (Horizontalfläche) aufweisen, der senkrecht zur Vertikalfläche liegt. Der Kontaktbereich kann aber auch eine anders orientierte Fläche aufweisen. Im Bereich 14, durch einen Kreis gekennzeichnet, kommt es im Notfall zu der beschriebenen Wechselwirkung bzw. Anlehnung und Abstützung zwischen zwei benachbarten Stufen 3. Diese Wechselwirkung führt dazu, dass sich die exzentrisch belastete vordere erste Stufe 3 über ihren Notführungshaken 13 gegen den Stufenkörper oder Stufenholm 3.2 der benachbarten hinteren Stufe 3 abstützt und dadurch ein Kippen der vorderen ersten Stufe 3 gestoppt oder verhindert wird.On the inside of the cheek, respectively the step spar 3.2, the emergency guide hook 13 is fastened with a nut 15 and an optional screw lock on the central axis of the roller 8. Details are the Fig. 5 refer to. In this figure is an enlarged plan view of the area between two successive stages. 3 Fig. 5 shows that the emergency guide hook 13 may be, for example, a stamped and bent sheet metal part, which rests with a vertical surface against the step spar 3.2. This vertical surface has a hole or a slit for screwing the emergency guide hook 13 to the axis of the roller 8. Furthermore, the emergency guide hook 13 has a contact area which is designed to interact with the step body or step rail 3.2 of the next stage 3 in the event of eccentric loading. This contact area can, as in Fig. 5 shown, a surface area (horizontal surface) which is perpendicular to the vertical surface. The contact area may also have a different oriented surface. In the area 14, characterized by a circle, it comes in an emergency to the described interaction or leaning and support between two adjacent stages 3. This interaction causes the eccentrically loaded front first stage 3 via their emergency guide hook 13 against the step body or Stair handle 3.2 of the adjacent rear stage 3 is supported and thereby tilting of the front first stage 3 is stopped or prevented.

Weitere Details sind der vergrössten Schnittdarstellung in Fig. 6 zu entnehmen. Es ist in Fig. 6 die gegenüberliegende Wange von innen zu sehen. Die Abbildung ist, anders als in Fig. 4, nicht schräg gezeigt. Mit anderen Worten ausgedrückt ist die Abbildung so gedreht worden, dass die Vorlaufschiene 5 horizontal verläuft. Von den Rollen 7 und 8 sind nur die Umrisse gezeigt. Auf der sichtbaren Innenseite der Wange, respektive des Stufenholms 3.2 ist der Notführungshaken 13 mit der Mutter 15 und einer optionalen Schraubensicherung 16 auf der Achse der Rolle 8 befestigt. Der Vertikalbereich 13.1 des Notführungshakens 13 liegt nun in der Zeichenebene. Der Kontaktbereich bzw. Flächenbereich 13.2 ist im gezeigten Ausführungsbeispiel schräg angestellt und ragt aus der Zeichenebene senkrecht heraus, d.h. der Kontaktbereich 13.2 weist von dieser Wange nach innen. Im Bereich 14, durch einen Kreis gekennzeichnet, kommt es im Notfall zur mechanischen Wechselwirkung mit der nächsten Stufe 3.Further details are the most enlarged sectional view in Fig. 6 refer to. It is in Fig. 6 to see the opposite cheek from the inside. The picture is different, unlike in Fig. 4 , not shown at an angle. In other words the image has been rotated so that the feed rail 5 is horizontal. Of the rollers 7 and 8, only the outlines are shown. On the visible inner side of the cheek, respectively the step spar 3.2, the emergency guide hook 13 is fastened with the nut 15 and an optional screw lock 16 on the axis of the roller 8. The vertical area 13.1 of the emergency guide hook 13 is now in the plane of the drawing. The contact area or surface area 13.2 is obliquely set in the embodiment shown and protrudes perpendicularly out of the plane of the drawing, ie the contact area 13.2 points inwards from this cheek. In area 14, indicated by a circle, in case of emergency mechanical interaction with the next stage 3 occurs.

In Fig. 7 ist eine weitere spezielle Ausgestaltung eines erfindungsgemässen Notführungshakens 13 zu erkennen. Der Notführungshaken 13 sitzt in der Verlängerung der Achse bzw. Mittelachse 8.1 der Rolle 8 (Die Rolle 8 ist nicht gezeigt) und ist nach aussen gerichtet (von dem Stufenholm 3.2 aus betrachtet rechts). Auf der Innenseite der Wange, respektive des Stufenholms 3.2 ist der Notführungshaken 13 mit einer Mutter 15 und einer optionalen Schraubensicherung 16 auf der Achse bzw. Mittelachse 8.1 der Rolle 8 befestigt. D.h., ein Vertikalbereich 13.1 des Notführungshakens 13 liegt flach an dem Stufenholm 3.2 an. Der Kontaktbereich 13.2 ist im gezeigten Beispiel anders ausgeführt. In diesem Bereich 13.2 sitzt ein Pufferelement 13.3 (zum Beispiel aus Gummi, Nylon oder Kunststoff, PA, PU, POM). Dieses Element kann mit dem Notführungshaken 13 zum Beispiel mittels einer Sechskantschraube und Mutter 13.4 verschraubt sein.In Fig. 7 shows a further special embodiment of an emergency guide hook 13 according to the invention. The emergency guide hook 13 sits in the extension of the axis or central axis 8.1 of the roller 8 (the roller 8 is not shown) and is directed outwards (viewed from the step spar 3.2 from the right). On the inside of the cheek, respectively the step spar 3.2, the emergency guide hook 13 is fastened with a nut 15 and an optional screw lock 16 on the axis or central axis 8.1 of the roller 8. That is, a vertical portion 13.1 of the emergency guide hook 13 is flat against the step spar 3.2. The contact area 13.2 is designed differently in the example shown. In this area 13.2 sits a buffer element 13.3 (for example, made of rubber, nylon or plastic, PA, PU, POM). This element can be screwed to the emergency guide hook 13, for example by means of a hex screw and nut 13.4.

Diese Art der Ausführungsform hat den Vorteil, dass die Wechselwirkung gedämpft wird. Durch eine geeignete Wahl bzw. Härte des Pufferelements 13.3 kann die Dämpfung eingestellt werden.This type of embodiment has the advantage that the interaction is damped. By a suitable choice or hardness of the buffer element 13.3, the damping can be adjusted.

Anstatt mit einem Pufferelement 13.3 zu arbeiten, kann auch ein Federelement entsprechend eingesetzt werden.Instead of working with a buffer element 13.3, a spring element can be used accordingly.

Die Ausführungsformen mit Puffer- oder Federelement 13.3 haben den Vorteil, dass sie auch im Normalbetrieb ein Aufschaukeln oder Schwingen der Stufen 3 bzw. des Stufenbandes unterbinden.The embodiments with buffer or spring element 13.3 have the advantage that they prevent rocking or oscillation of the steps 3 or of the step belt even in normal operation.

Es ist auch möglich an der jeweils benachbarten Stufe 3 ein Puffer- oder Federelement 13.3 anzubringen, damit der Notführungshaken 13 nicht auf eine metallische Fläche auftrifft und zum Beispiel Geräusche verursacht.It is also possible to attach a buffer or spring element 13.3 to the respectively adjacent step 3, so that the emergency guide hook 13 does not impinge on a metallic surface and cause, for example, noise.

Es wird als ein wesentlicher Vorteil der notführungsschienenfreien Ausführungsform angesehen, dass keine Geräusche auftreten. Ausserdem ist die Montage sehr viel einfacher und kostengünstiger.It is considered to be a significant advantage of the notch-rail-free embodiment that no noise occurs. In addition, the assembly is much easier and cheaper.
