Description

Die Erfindung betrifft eine Befestigungsvorrichtung für die mit zwei auf einer Laufschiene abgestützen Schlepprollen ausgerüsteten Stufen einer Fahrtreppe an je einer seitlich neben den Stufen angeordneten durch Kettenrollen auf einer Führungsschiene abgestützten, endlosen Transportkette zur Bildung eines aus einem Vorlauf und einem Rücklauf je mit horizontalen und schrägen mit Übergangsbögen versehenen Laufbahnen bestehenden endlosen Stufenbandes.The invention relates to a fastening device for the stages of an escalator equipped with two trailing rollers supported on a running rail, each on an endless transport chain arranged laterally next to the steps and supported by chain rollers on a guide rail, to form a chain comprising a forward and a return, each with horizontal and inclined Transition arches provided with existing endless step belt.

Es sind verschiedene Fahrtreppenkonstruktionen bekannt, bei welchen die Stufen an einer die beiden Transportketten miteinander verbindenden, an den verlängerten Gelenkzapfen der Transportkette angeordneten Stufenachsen befestigt sind, wobei zwischen dem Körper der Stufen und den Stufenachsen auch elastische Elemente zur Dämpfung von Erschütterungen und Geräuschen eingesetzt werden.Various escalator designs are known in which the steps are attached to a step axis connecting the two transport chains and arranged on the extended pivot pin of the transport chain, elastic elements for damping vibrations and noises also being used between the body of the steps and the step axes.

Eine solche Befestigungsvorrichtung für die Trittstufen einer Fahrtreppe oder eines Personenförderbandes ist mit der DE-OS-2 342 849 bekanntgeworden, bei welcher die einzelnen Trittstufen mittels Klemmbacken an einer die beiden Transportketten miteinander verbindenden Stufenachse befestigt sind. Diese Befestigungsvorrichtungen sind auf beiden Seiten des Stufenkörpers angeordnet und zweiteilig ausgeführt. Sie bestehen aus je einer festen am Stufenkörper angeordneten Lagerhälfte und der schwenkbar mit dem Stufenkörper verbundenen und mit einem Ansatz versehenen Klemmbacke. Beim Einsetzen einer Stufe legt sich die Klemmbacke mit Hilfe des Ansatzes selbsttätig um die Stufenachse. In dieser Lage kann die schwenkbare Lagerhälfte von aussen, beispielsweise durch eine Schraube, starr mit dem Stufenkörper verbunden werden. Damit Erschütterungen und Geräusche gedämpft werden, sind zwischen den Stufenachsen und der Stufenbefestigung zusätzlich Muffen aus elastischem Werkstoff vorgesehen. Diese Befestigungsvorrichtung für Trittstufen hat den Vorteil, dass der Ausbau und der Einbau von einzelnen Stufen für Wartungszwecke ohne zusätzliche Vorbereitungsarbeiten auf einfachste Art vorgenommen werden kann.Such a fastening device for the steps of an escalator or a passenger conveyor belt has become known from DE-OS-2 342 849, in which the individual steps are fastened to a step axis connecting the two transport chains by means of clamping jaws. These fastening devices are arranged on both sides of the step body and are made in two parts. They each consist of a fixed bearing half arranged on the step body and the clamping jaw which is pivotally connected to the step body and provided with an attachment. When inserting a step, the jaw automatically lays around the step axis using the attachment. In this position, the pivotable bearing half can be rigidly connected to the step body from the outside, for example by a screw. In order to dampen vibrations and noises, additional sleeves made of elastic material are provided between the step axes and the step fastening. This fastening device for steps has the advantage that the removal and installation of individual steps for maintenance purposes can be carried out in the simplest way without additional preparation work.

Ein Nachteil dieser Stufenbefestigung, der auch den meisten anderen, bekannten Fahrtreppenkonstruktionen anhaftet, liegt aber darin, dass sich trotz den zwischen den Stufenachsen und dem Stufenkörper eingesetzten Dämpfungselementen Erschütterungen von den Laufbahnen bzw. von den Transportketten auf den Stufenkörper übertragen und Laufgeräusche entstehen. Solche Laufgeräusche machen sich hauptsächlich bei Kompaktstufen, welche im Pressgussverfahren in einem einzigen Stück hergestellt sind, unangenehm bemerkbar, und zwar beim Holpern der Stufen in unbelastetem Zustand über verschmutzte Laufbahnen.A disadvantage of this step attachment, which also adheres to most other known escalator designs, is that despite the damping elements used between the step axes and the step body, vibrations are transmitted from the raceways or from the transport chains to the step body and running noises occur. Such running noises are noticeably noticeable mainly in the case of compact steps, which are produced in a single piece by the press casting process, namely when the steps are bumped in an unloaded state over soiled tracks.

Zum Dämpfen solcher Laufgeräusche wurde schon vorgeschlagen, die Hohlräume dieser Kompaktstufen mindestens teilweise mit einer Antidröhnmasse zu versehen. Damit werden wohl Verbesserungen erreicht, die aber in keinem Verhältnis zu dem dazu nötigen Aufwand stehen.To dampen such running noises, it has already been proposed to provide the cavities of these compact stages with an anti-drumming compound at least in part. Improvements are probably achieved in this way, but they are disproportionate to the effort required.

Ein weiterer Nachteil dieser und der meisten übrigen bekannten Fahrtreppenkonstruktionen liegt noch darin, dass die während des Betriebes zwischen dem Stufenkörper und der Stufenachse stattfindende Relativbewegung sich als Drehbewegung der Dämpfungsmuffe auf der Stufenachse auswirkt. Diese Muffen sind meistens nur mangelhaft abgedichtet und werden vor allem bei Fahrtreppen, die ganz oder teilweise im Freien aufgestellt und einer starken Verschmutzung ausgesetzt sind, schnell abgenutzt und geben dadurch Anlass zu weiteren Geräuschen und Störungen.Another disadvantage of this and most of the other known escalator designs is that the relative movement that takes place between the step body and the step axis during operation has the effect of a rotary movement of the damping sleeve on the step axis. These sleeves are usually poorly sealed and are quickly worn out, especially on escalators that are partially or completely set up outdoors and are exposed to heavy soiling, and give rise to further noise and malfunctions.

Der Erfindung liegt die Aufgabe zugrunde, eine Befestigungsvorrichtung für die Trittstufen einer Fahrtreppe vorzuschlagen, bei welcher das Holpern der Stufen besser gedämpft wird und bei welcher durch die Relativbewegungen zwischen der Stufe und dem Stufentransportmittel praktisch keine Lagerabnutzung entsteht.The invention has for its object to provide a fastening device for the steps of an escalator, in which the bumping of the steps is better damped and in which there is practically no bearing wear due to the relative movements between the step and the step transport means.

Diese Aufgabe wird durch die in den Ansprüchen gekennzeichnete Erfindung gelöst.This object is achieved by the invention characterized in the claims.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass das durch das elastische Gelenk auf die Stufe ausgeübte Drehmoment die Schlepprollen der Stufe auch im Leerlauf in den schrägen Führungsbahnen des Stufen-Vorlaufes und in den daran anschliessenden Übergangsbögen an die Laufschienen gedrückt werden. Dadurch heben sich die Stufen auch durch verschmutzte Laufschienen oder durch Beschleunigungskräfte nicht von der Lauffläche ab und ein anschliessendes Aufschlagen der Schlepprollen auf die Laufschiene mit der damit verbundenen Geräuschbildung wird verhindert. Ein teures Ausspritzen der Stufenkörper mit einer Antidröhnmasse erübrigt sich.The advantages achieved by the invention are essentially to be seen in the fact that the torque exerted on the step by the elastic joint presses the towing rollers of the step even when idling in the inclined guideways of the step advance and in the transition arches which follow it on the running rails . As a result, the steps do not lift off the tread due to soiled running tracks or acceleration forces, and subsequent tapping of the drag rollers onto the running track with the associated noise is prevented. Expensive spraying of the step body with an anti-drumming compound is unnecessary.

Ein weiterer Vorteil der Erfindung liegt darin, dass das elastische Gelenk praktisch keiner Abnutzung unterworfen ist, da keine Lagerreibung stattfindet. Dieser Vorteil ist vor allem bei Freiluftanlagen mit einem hohe Verschmutzungsgrad von grosser Wichtigkeit, da weder Feuchtigkeit noch Schmutz das elastische Gelenk stark beeinflusst.Another advantage of the invention is that the elastic joint is practically not subject to wear, since there is no bearing friction. This advantage is particularly important for open-air systems with a high degree of pollution, since neither moisture nor dirt strongly influences the elastic joint.

These are an elastic joint 4 consisting of an outer body 4.1, an inner body 4.2 and a number of spacing damping bodies 4.3 and a holding plate 7 inserted into a support groove 1.5 in the body of step 1 and fastened to it by a screw 8 the outer body 4.1 of the elastic joint 4 is held against rotation in a recess 1.4 of the body of stage 1. The drag roller 2 is guided on a running rail 5 and a chain roller 3 of the transport chain 10 on a guide rail 6.

In den Fig. 3, 4, 5 und 6 wird eine mögliche Befestigungsvorrichtung 9 an einem Aussenglied 10.2 bzw. an einem Innenglied 10.1 der Transportkette 10 gezeigt. In der im Seitenschild 1.3 der Stufe 1 vorgesehenen Aussparung 1.4 ist der Aussenkörper 4.1 des elastischen Gelenkes 4 verdrehsicher eingelegt und durch die Halteplatte 7 gesichert. In den Innenkörper 4.2 des elastischen Gelenkes 4 greift ein an einem als Tragelement dienenden Support 11 angeordneter Mitnehmerbolzen 12 ein. Der Support 11 liegt auf den Laschen 10.3, 10.4 eines Innengliedes 10.1 oder eines Aussengliedes 10.2 der Transportkette 10 auf und wird mittels eines Verankerungselementes 15 verbunden, welches einen in eine Bohrung 10.5 der Laschen 10.3, 10.4 des Kettengliedes 10.1, 10.2 eingreifbaren Zapfen 15.1 aufweist. Das Verankerungselement 15 ist am Support 11 mittels einer Schraube 16 und einer Mutter 17 festgeklemmt, wobei die Schraube 16 bei der Befestigung an einem Aussenglied 10.2 in einer inneren Führungsbohrung 11.2 und bei der Befestigung an einem Innenglied 10.1 in einer äusseren Führungsbohrung 11.1 geführt ist. Zur Vermeidung einer Lüngsverschiebung des Supports 11 besitzt der der Seite des Kettengliedes zugewandte Teil des Supports 11 Rippen 11.3, die in entsprechende in den Laschen 10.3, 10.4 vorgesehene obere Aussparungen 10.6 eingreifen. Als zusätzliche Sicherung gegen das Verdrehen des Supports 11 dient ein am unteren Ende des Supports 11 angeordneter ebenfalls in eine in den Laschen 10.3, 10.4 vorgesehene untere Aussparung 10.7 eingreifender Lappen 11.4.3, 4, 5 and 6, a possible fastening device 9 is shown on an outer link 10.2 or on an inner link 10.1 of the transport chain 10. In the recess 1.4 provided in the side plate 1.3 of the step 1, the outer body 4.1 of the elastic joint 4 is inserted against rotation and secured by the holding plate 7. A driver pin 12 arranged on a support 11 serving as a supporting element engages in the inner body 4.2 of the elastic joint 4. The support 11 lies on the plates 10.3, 10.4 of an inner link 10.1 or an outer link 10.2 of the transport chain 10 and is connected by means of an anchoring element 15 which has a pin 15.1 which can be engaged in a bore 10.5 of the plates 10.3, 10.4 of the chain link 10.1, 10.2. The anchoring element 15 is clamped to the support 11 by means of a screw 16 and a nut 17, the screw 16 being guided in an inner guide bore 11.2 when fastened to an outer member 10.2 and in an outer guide bore 11.1 when fastened to an inner member 10.1. In order to avoid a shift in the length of the support 11, the part of the support 11 which faces the side of the chain link has ribs 11.3 which engage in corresponding upper cutouts 10.6 provided in the plates 10.3, 10.4. A tab 11.4, which is arranged at the lower end of the support 11 and also engages in a lower recess 10.7 provided in the tabs 10.3, 10.4, serves as additional protection against the rotation of the support 11.

In der in der Fig. 7 gezeigten Ausführungsvariante wird ein Support 19 mit jedem Kettenglied 10.1, 10.2 mit den gleichen in den Fig. 3-6 gezeigten Verankerungselementen und Sicherungseinrichtungen verbunden. Der Support 19 besitzt eine zur verdrehsicheren Aufnahme des Aussenkörpers 4.1 des elastischen Gelenkes 4 vorgesehene Bohrung 19.1. Im Körper einer Stufe 21 ist ein Mitnehmerbolzen 22 mit einem zylindrischen Lagerteil 22.1 und einem Knopfgriff 22.2 gelagert. Eine Sicherungsfeder 13 hindert den Mitnehmerbolzen 22 am Drehen und am Verschieben. Die gerillte Trittfläche der Stufe 21 erhält die Ziffer 21.1 und das Seitenschild der Stufe die Ziffer 21.3.In the embodiment variant shown in FIG. 7, a support 19 is connected to each chain link 10.1, 10.2 with the same anchoring elements and securing devices shown in FIGS. 3-6. The support 19 has a bore 19.1 provided for the rotationally secure reception of the outer body 4.1 of the elastic joint 4. A driver pin 22 with a cylindrical bearing part 22.1 and a button handle 22.2 is mounted in the body of a step 21. A locking spring 13 prevents the driving pin 22 from rotating and shifting. The grooved tread of level 21 receives number 21.1 and the side plate of level 21.3.

In der Fig. 8 ist das endlose aus einem Vorlauf 14.1 und einem Rücklauf 14.2 bestehende Stufenband 14 schematisch dargestellt. Der Vorlauf 14.1 des Stufenbandes 14 setzt sich aus einer unteren horizontalen 14.3, einer schrägen 14.4 und einer oberen horizontalen Laufbahn 14.5 zusammen. Die an den Förderketten 10 befestigten Stufen 1 weisen je eine gerillte Trittfläche 1.1, ein gerilltes Stirnteil 1.2 und zwei Schlepprollen 2 auf. Zwischen den Laschen oder neben den Laschen der Kettenglieder 10.1, 10.2 der Transportkette 10 sind die Kettenrollen 3 angeordnet. Die Schlepprolle 2 ist auf der Laufschiene 5 und die Kettenrolle auf der Führungsschiene 6 geführt.8, the endless step belt 14 consisting of a forward flow 14.1 and a return 14.2 is shown schematically. The lead 14.1 of the step belt 14 is composed of a lower horizontal 14.3, an oblique 14.4 and an upper horizontal track 14.5. The steps 1 fastened to the conveyor chains 10 each have a grooved tread surface 1.1, a grooved front part 1.2 and two drag rollers 2. The chain rollers 3 are arranged between the plates or next to the plates of the chain links 10.1, 10.2 of the transport chain 10. The drag roller 2 is guided on the running rail 5 and the chain roller on the guide rail 6.

Die beschriebene Einrichtung arbeitet wie folgt: Das zwischen den einzelnen Stufen 1, 21 und den Transportketten 10 vorgesehene elastische Gelenk 4 ist so eingebaut, dass mindestens im Bereich des Schrägteiles 14.4 des Vorlaufes 14.1 des Stufenbandes 14 und in den daran anschliessenden Übergangsbögen auf die Stufen 1, 21 ein Drehmoment ausgeübt wird, derart, dass eine Kraft auf die Schlepprollen 2 wirkt. Die Schlepprollen 2 werden dadurch während des Betriebes an die Laufschienen 5 gedrückt und die Stufe 1 kommt im Leerlauf auch bei verschmutzten Laufschienen 5 nicht zum Holpern.The device described works as follows: the elastic joint 4 provided between the individual steps 1, 21 and the transport chains 10 is installed in such a way that at least in the area of the inclined part 14.4 of the lead 14.1 of the step belt 14 and in the transition arches connected thereafter to the steps 1 , 21 a torque is exerted such that a force acts on the drag rollers 2. The trailing rollers 2 are thereby pressed against the running rails 5 during operation and the stage 1 does not come to a halt when the running rails 5 are idle, even when they are dirty.

Es liegt im Rahmen der Erfindung, andere, als in den Figuren 3 bis 7 gezeigte Befestigungsvorrichtungen mit elastischen Gelenken für den Anschluss der Stufen an den Laschen oder Gliedern der Transportkette vorzusehen. Ausserdem wäre es möglich, die Stufen mit einem elastischen Gelenk auf einer Verlängerung einer Gelenkverbindung der Transportketten oder auf einer die beiden Transportketten miteinander verbindenden Achse zu lagern. Ebenso liegt es im Rahmen der Erfindung, anstelle des in der Fig. 2 gezeigten elastischen Gelenkes ein solches in einer anderen Ausführungsform einzusetzen.It is within the scope of the invention to provide fastening devices other than those shown in FIGS. 3 to 7 with elastic joints for connecting the steps to the link plates or links of the transport chain. It would also be possible to mount the steps with an elastic joint on an extension of a joint connection of the transport chains or on an axis connecting the two transport chains to store. It is also within the scope of the invention to use one in another embodiment instead of the elastic joint shown in FIG. 2.

Anstelle der in Fig. 2 gezeigten in eine Stützrille im Körper der Stufe eingelegte Halteplatte könnte auch eine mit einem Scharnier am Körper der Stufe schwenkbar angeordnete Halteplatte vorgesehen sein.Instead of the holding plate shown in FIG. 2, which is inserted into a support groove in the body of the step, a holding plate pivotably arranged with a hinge on the body of the step could also be provided.

Bei der in der Fig. 7 gezeigten Befestigungsvorrichtung könnte anstelle des vorgeschlagenen mit einem Knopfgriff versehenen Mitnehmerbolzens auch ein Mitnehmerbolzen mit einer Druckfeder vorgesehen sein.
