Description

Die Erfindung betrifft eine Stufe für eine Fahrtreppe, wobei die Stufe als einstückiges Leichtmetalldruckgussteil ausgebildet ist beinhaltend eine Trittplatte, eine Schürze, mindestens eine Querrippe, Führungsaugen, wobei die Führungsaugen ausschliesslich an der Schürze befestigt sind und Antriebsaugen.The invention relates to a step for an escalator, wherein the step is formed as a one-piece light metal die-cast part comprising a tread plate, an apron, at least one transverse rib, guide eyes, wherein the guide eyes are fastened exclusively to the apron and drive eyes.

Aus dem Stand der Technik sind verschiedenen Herstell- und Aufbauarten von Stufen für Fahrtreppen bekannt. Die WO 2009/047144 A1 offenbart eine Stufe, die aus tiefgezogenen Blechen zusammengebaut ist. Dies hat den Nachteil einer aufwendigen Montage was hohe Kosten zur Folge hat.Various types and designs of steps for escalators are known from the prior art. The WO 2009/047144 A1 discloses a step assembled from deep-drawn sheets. This has the disadvantage of a complex assembly which has high costs.

Die DE 299 09 808 U1 offenbart eine Stufe, die aus glasfaserverstärktem Kunststoff hergestellt ist und mehrere Rippen und Verstärkungen zur Versteifung aufweist.The DE 299 09 808 U1 discloses a step made of glass fiber reinforced plastic having a plurality of ribs and reinforcements for stiffening.

Die EP 2 173 652 B1 offenbart ein Trittelement, das aus Aluminiumdruckguss hergestellt ist und das bis auf die Leisten einstückig ausgebildet ist.The EP 2 173 652 B1 discloses a tread element which is made of die-cast aluminum and which is integrally formed except for the strips.

Die JP 2012 201485 A offenbart eine Stufe für eine Fahrtreppe, wobei die Stufe als Leichtmetalldruckgussteil ausgebildet ist, beinhaltend eine Trittplatte, eine Schürze, Führungsaugen, wobei die Führungsaugen ausschliesslich an der Schürze befestigt sind und Antriebsaugen, wobei die Antriebsaugen jeweils ausschliesslich mit einem Verbindungssteg an der Stufe befestigt bzw. angeordnet sind.The JP 2012 201485 A discloses a step for an escalator, wherein the step is formed as a light metal die casting, including a tread plate, an apron, guide eyes, the guide eyes are fastened exclusively to the apron and drive eyes, the drive eyes in each case exclusively with a connecting web attached to the step or are arranged.

Der Nachteil an dem oben erwähnten Trittelement liegt darin, dass ein hoher Materialaufwand aufgrund der vorliegenden Verstrebungen zur Erzielung der erforderlichen Festigkeit und Steifigkeit nötig ist.The disadvantage of the above-mentioned tread element is that a high cost of materials due to the present bracing to achieve the required strength and rigidity is necessary.

Es ist Aufgabe der Erfindung eine Stufe und ein damit verbundenes Verfahren vorzuschlagen, dass die Herstellkosten aufgrund Materialreduktion und einer Verkürzung der Zykluszeit während des Giessverfahrens verringert und dennoch den Anforderungen an die Steifigkeit und Festigkeit gerecht wird.It is an object of the invention to propose a stage and a method associated therewith, that reduces the manufacturing costs due to material reduction and a shortening of the cycle time during the casting process and still meets the requirements of rigidity and strength.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass die Antriebsaugen jeweils ausschliesslich mit einem Verbindungssteg an der Stufe befestigt bzw. angeordnet sind. Die vorliegende Erfindung zeichnet sich dadurch aus, dass Material bzw. Gussmaterial in der Herstellung der Stufe eingespart werden kann indem auf Verbindungs- bzw. Versteifungsstreben verzichtet werden kann. Im Stand der Technik weisen die bisher bekannten Stufen in der Regel einen Verbindungssteg zwischen Antriebsauge und Führungsauge auf um die benötigte Steifigkeit wie auch Festigkeit der Stufe zu erhalten.This object is achieved according to the invention in that the drive eyes are fastened or arranged exclusively with a connecting web on the step. The present invention is characterized in that material or casting material can be saved in the production of the stage by can be dispensed with connecting or stiffening struts. In the prior art, the previously known stages usually have a connecting web between drive eye and guide eye in order to obtain the required rigidity as well as strength of the stage.

Die erfindungsgemässe Stufe ist ein Leichtmetalldruckgussteil das aus einem Stück gebildet ist. Die Stufe beinhaltet eine Trittplatte, eine Schürze, mindestens eine Querrippe, wobei die Querrippe vorzugsweise an der Unterseite der Trittplatte angeordnet ist und zur Erzielung der benötigten Stabilität und Festigkeit der Trittplatte gedacht ist. Die Querrippe erstreckt sich vorzugsweise zwischen den beiden Verbindungsstegen der Antriebsaugen bzw. bis hin zu den Randbereichen der Stufe. Zudem beinhaltet die Stufe Führungsaugen, wobei diese ausschliesslich an der Schürze angeordnet bzw. angeformt sind. Die Führungsaugen sind in den beiden Randbereichen der Stufe angeordnet.The inventive step is a Leichtmetalldruckgussteil which is formed from one piece. The step includes a tread plate, an apron, at least one transverse rib, the transverse rib preferably located at the bottom of the tread plate and intended to provide the required stability and strength of the tread plate. The transverse rib preferably extends between the two connecting webs of the drive eyes or up to the edge regions of the step. In addition, the step includes guide eyes, which are arranged or molded exclusively on the apron. The guide eyes are arranged in the two edge regions of the step.

Die erfindungsgemässe Stufe weist jeweils auf beiden Seiten der Stufe, gesehen in Fahrtrichtung, ein Antriebs- und Führungsauge auf bzw. in den Randbereichen der Stufe. Das Antriebsauge ist mit der Antriebskette der Fahrtreppe verbunden. Das Führungsauge dient mit einer daran befestigten Rolle der Führung der Stufe und so der Fahrtreppe. Das Antriebsauge bzw. die beiden Antriebsaugen, die eine Stufe beinhaltet, sind mit der Stufe ausschliesslich über jeweils einen Verbindungssteg verbunden. Die Antriebsaugen werden von keinem weiteren Steg stabilisiert, sie sind jeweils nur mittels eines Verbindungsstegs an der Stufe angeordnet und befestigt. Das Antriebsauge kann als geschlossener Ring wie auch als einseitig offenes Ringsegment ausgestaltet sein.
Am Antriebsauge setzt sich ausschliesslich der Verbindungssteg fort, welcher sich an die Stufe anformt. Vorzugsweise ist der Verbindungssteg zum Antriebsauge an der Trittplatte der Stufe angeordnet, speziell bevorzugt an der Unterseite der Trittplatte.The inventive step has in each case on both sides of the step, seen in the direction of travel, a drive and guide eye on or in the edge regions of the step. The drive eye is connected to the drive chain of the escalator. The guide eye is used with a role attached to the leadership of the stage and so the escalator. The drive eye or the two drive eyes, which includes a stage, are connected to the stage exclusively via a respective connecting web. The drive eyes are stabilized by any other web, they are each arranged and fixed only by means of a connecting web to the stage. The drive eye can be designed as a closed ring as well as unilaterally open ring segment.
At the drive eye is continued exclusively the connecting web, which is formed on the step. Preferably, the connecting web is arranged to the drive eye on the tread plate of the step, especially preferably on the underside of the tread plate.

Die Stufe fällt symmetrisch aus, weshalb nicht immer speziell erwähnt wird, dass die Stufe jeweils zwei Antriebsaugen und Führungsaugen sowie Verbindungsstege aufweist.
Das Antriebsauge und das Führungsauge des jeweiligen Randbereichs der Stufe liegen vorzugsweise in einer Flucht, wobei die Flucht in Fahrtrichtung der Stufe verläuft.The stage is symmetrical, which is why it is not always mentioned specifically that the stage has two drive eyes and guide eyes as well as connecting webs.
The drive eye and the guide eye of the respective edge region of the step are preferably in alignment with the escape running in the direction of travel of the step.

Die Führungsaugen sind über die Schürze an der Stufe befestigt bzw. daran angeformt. Dadurch, dass die Augen jeweils nur in einer Ausrichtung mit der Stufe verbunden sind und keine weiteren Verstrebungen aufweisen und auch keine Verstrebung zwischen Trittplatte und Schürze vorliegen, ist die Stufe gegen unten über die komplette Breite offen.
Diese offene Ausgestaltung der Stufe ermöglicht eine Verkürzung der Zykluszeiten beim Giessen, da aufgrund dessen, die Form bzw. das Gusswerkzeug einfacher gestaltet werden kann und im besten Fall sogar durch nur zwei Halbschalen gebildet werden kann um die Stufe nach dem Giessvorgang auch auszuformen. Das heisst, auf zusätzliche Schieber am Gusswerkzeug kann verzichtet werden, was eine Verkürzung der Zykluszeit zur Folge hat.The guide eyes are attached to the apron on the step or formed on it. Due to the fact that the eyes are connected to the step in one orientation only and have no further braces and none Strut between tread plate and apron, the step is open towards the bottom across the entire width.
This open design of the stage allows a shortening of the cycle times during casting, as a result of which, the mold or the casting tool can be made simpler and in the best case can even be formed by only two half-shells to form the stage after the casting process. This means that additional slides on the casting tool can be dispensed with, which results in a shortening of the cycle time.

Bei zusätzlich benötigten Streben an der Stufe wie es aus dem Stand der Technik bekannt ist, reichen zwei Halbschalen nicht aus um die Stufe ausformen zu können da durch solche Streben Hinterschnitte gebildet werden und dies nur durch weitere Schieber an der Gussform gelöst werden kann. Dies wiederum erhöht die Zykluszeit um eine Form zu öffnen und die Stufe auszuformen, was bei einer solch hohen Anzahl an herzustellenden Stufen ins Gewicht fällt.
Da die Antriebs- und Führungsaugen nicht miteinander bzw. nicht untereinander verbunden sind verläuft keine Strebe dazwischen und die Stufe ist somit über ihre komplette Breite nach unten offen gestaltet.With additionally required struts at the stage, as is known from the prior art, two half-shells are not sufficient to be able to form the step since undercuts are formed by such struts and this can only be solved by further slides on the mold. This, in turn, increases the cycle time to open a mold and form the step, which is significant with such a high number of steps to be made.
Since the drive and guide eyes are not connected to each other or not to each other, no strut intervenes and the step is thus designed open over its entire width down.

Die Stufe weist vorzugsweise in den Randbereichen Verstärkungsrippen auf. Die Verstärkungsrippen sollen der Steifigkeit und Festigkeit der Stufe dienen. Es ist von Vorteil, wenn die Verstärkungsrippen in derselben Flucht mit dem Antriebs- und Führungsauge liegen.
Die Verstärkungsrippen verlaufen entlang der Innenseite der Schürze und der Unterseite der Trittplatte und dienen der Erhöhung der Stabilität der Stufe und verunmöglichen ein Abknicken der Trittplatte gegenüber der Schürze.
Die an die Schürze und Trittplatte angeformten Verstärkungsrippen weisen im Übergang vom Bereich der Schürze in den Bereich der Trittplatte einen Radius auf. Als vorteilhaft hat sich gezeigt, dass die Verstärkungsrippe eine minimale Höhe von 8 mm aufweisen sollte.
Die Verstärkungsrippe kann in den unterschiedlichen Bereichen auch unterschiedliche Höhen aufweisen, das heisst, beispielsweise kann die Höhe der Verstärkungsrippe entlang der Unterseite der Trittplatte 10 mm betragen und im Bereich der Innenseite der Schürze nur 8 mm, selbstverständlich sind auch andere Kombinationen möglich.The step preferably has reinforcing ribs in the edge regions. The reinforcing ribs are intended to serve the rigidity and strength of the step. It is advantageous if the reinforcing ribs lie in the same alignment with the drive and guide eye.
The reinforcing ribs run along the inside of the skirt and the underside of the tread plate and serve to increase the stability of the step and make it impossible for the tread plate to buckle with respect to the skirt.
The reinforcing ribs formed on the skirt and tread plate have a radius in the transition from the area of the skirt to the area of the tread plate. It has proven advantageous that the reinforcing rib should have a minimum height of 8 mm.
The reinforcing rib may also have different heights in the different regions, that is, for example, the height of the reinforcing rib along the underside of the tread plate may be 10 mm and in the Area of the inside of the apron only 8 mm, of course, other combinations are possible.

Fig. 1 zeigt eine dreidimensionale Ansicht einer erfindungsgemässen Stufe 1 für eine Fahrtreppe. Die Stufe 1 ist als einstückiges Leichtmetalldruckgussteil ausgebildet, wodurch hohe Komplettierungskosten für die einzelnen Stufen vermieden werden können. Die Stufe 1 beinhaltet eine Trittplatte 2, eine Schürze 3, mindestens eine Querrippe 4 zur Versteifung der Trittplatte 2, wobei die Querrippe 4 vorzugsweise an der Unterseite der Trittplatte 2 angeordnet ist, Führungsaugen 5, wobei die Führungsaugen 5 ausschliesslich an der Schürze 3 angeordnet sind. Das heisst, dass sich in den beiden Randbereichen 9 der Stufe 1, bzw. der Schürze 3 der Stufe 1, gesehen in Fahrtrichtung, zwei Führungsaugen 5 erstrecken bzw. angeformt sind. Diese dienen der Führung der Stufe 1 bzw. der Fahrtreppe. Die Stufe 1 beinhaltet zudem Antriebsaugen 6, die mithilfe der Kette einer Fahrtreppe angetrieben werden, wobei die Antriebsaugen 6 der Stufe 1 jeweils in den beiden Randbereichen 9 der Stufe 1 angeordnet sind. Die Antriebsaugen 6 sind mittels jeweils eines Verbindungsstegs 7 mit der Stufe 1 verbunden bzw. an der Trittplatte angeformt. In den Fig. 2 - 4 ist die Anformung der Augen 5, 6 durch die gedrehte Darstellung der Stufe 1 gut ersichtlich. Fig. 1 shows a three-dimensional view of an inventive step 1 for an escalator. Stage 1 is designed as a one-piece light-alloy die-cast part, whereby high completion costs for the individual stages can be avoided. The step 1 includes a tread plate 2, a skirt 3, at least one transverse rib 4 for stiffening the tread plate 2, wherein the transverse rib 4 is preferably arranged on the underside of the tread plate 2, guide eyes 5, wherein the guide eyes 5 are arranged exclusively on the skirt 3 , This means that in the two edge regions 9 of the stage 1, or the apron 3 of the stage 1, seen in the direction of travel, two guide eyes 5 extend or are formed. These serve to guide level 1 or the escalator. The stage 1 also includes drive eyes 6, which are driven by means of the chain of an escalator, wherein the drive eyes 6 of the stage 1 are respectively arranged in the two edge regions 9 of the stage 1. The drive eyes 6 are connected by means of a respective connecting web 7 with the stage 1 or formed on the tread plate. In the Fig. 2-4 is the Anformung of the eyes 5, 6 clearly visible by the rotated representation of level 1.

Die Antriebsaugen 6 sind vorzugsweise an der Unterseite der Trittplatte 2 angeformt. Die Antriebsaugen 6 und Führungsaugen 5 am jeweiligen Randbereich 9 der Stufe 1 liegen vorzugsweise in einer Flucht. Die Antriebs- und Führungsaugen 5, 6 weisen aber keine Verbindungsstreben zueinander auf. Da auch sonst keine Verbindungsstreben zwischen Schürze 3 und Trittplatte 2 bestehen ist die Stufe 1 über die komplette Breite nach unten offen. Diese Gestaltung der Stufe 1 ermöglicht einen einfacheren Aufbau des Gusswerkzeugs zur Herstellung der Stufe 1. Dadurch kann auf weitere Schieber am Gusswerkzeug verzichtet werden. Dies verkürzt die Zeiten zur Ausformung der Stufe 1.The drive eyes 6 are preferably integrally formed on the underside of the tread plate 2. The drive eyes 6 and guide eyes 5 at the respective edge region 9 of the stage 1 are preferably in alignment. The drive and guide eyes 5, 6 point but no connecting struts to each other. Since otherwise also no connecting struts between skirt 3 and tread plate 2 is the level 1 is open over the entire width down. This design of stage 1 allows a simpler structure of the casting tool for the production of the stage 1. This can be dispensed with further slide on the casting tool. This shortens the times for forming the stage 1.

Um die benötigte Stabilität und Festigkeit der Stufe 1 trotz fehlender Verstrebungen zwischen Schürze 3 und Trittplatte 2 zu gewährleisten, sind in den beiden Randbereichen 9 jeweils Verstärkungsrippen 8 angeordnet.In order to ensure the required stability and strength of the stage 1, despite the lack of bracing between the skirt 3 and tread plate 2, 9 each reinforcing ribs 8 are arranged in the two edge regions.

Vorzugsweise verlaufen die Verstärkungsrippen 8 in der Flucht der Antriebs- und Führungsaugen 5, 6 des jeweiligen Randbereichs 9.The reinforcing ribs 8 preferably extend in alignment with the drive and guide eyes 5, 6 of the respective edge region 9.

Die Verstärkungsrippen 8 verlaufen entlang der Innenseite der Schürze 3 und der Unterseite der Trittplatte 2. Die Verstärkungsrippen 8 verlaufen parallel zur Fahreinrichtung der Stufe 1 bzw. einer Fahrtreppe.The reinforcing ribs 8 extend along the inside of the skirt 3 and the underside of the tread plate 2. The reinforcing ribs 8 are parallel to the driving device of the stage 1 or an escalator.

Die Verstärkungsrippen 8 erstrecken sich entlang der Schürze 3 und weisen im Übergang zur Trittplatte 2 einen Radius auf.The reinforcing ribs 8 extend along the skirt 3 and have a radius in the transition to the tread plate 2.

Vorzugsweise weist die Höhe der Verstärkungsrippe 8 mindestens 8 mm auf. Die Höhe der Verstärkungsrippen 8 kann im Bereich der Schürze 3 und im Bereich der Trittplatte 2 auch unterschiedlich ausfallen.Preferably, the height of the reinforcing rib 8 at least 8 mm. The height of the reinforcing ribs 8 may also be different in the region of the skirt 3 and in the region of the tread plate 2.

Die Schürze 3, die Verstärkungsrippen 8, die Querrippe 4 und die zwischen der Querrippe 4 und den Verstärkungsrippen 8 angeordneten Verbindungsstreben 6 bilden einen geschlossenen Rahmen vorzugsweise an der Unterseite der Trittplatte 2, wodurch die benötigte Stabilität und Festigkeit der Stufe erreicht wird.The skirt 3, the reinforcing ribs 8, the transverse rib 4 and the connecting struts 6 arranged between the transverse rib 4 and the reinforcing ribs 8 form a closed frame, preferably on the underside of the step plate 2, whereby the required stability and strength of the step is achieved.
