Description

Die Erfindung betrifft eine Fahrtreppe oder einen Fahrsteig, gemäss dem Oberbegriff von Anspruch 1.The invention relates to an escalator or moving walk, according to the preamble of claim 1.

Die Abstützung der Stufen von Fahrtreppen und der Paletten von Fahrsteigen erfolgt üblicherweise über Kettenrollen und Stützrollen, die auf je zugeordneten Schienen laufen. Im Rücklauf müssen die Stufen oder Paletten kopfüber transportiert werden, und an den Enden des Fahrsteigs oder der Fahrtreppe muss je eine Umlenkung vorgenommen werden. Dies bedingt, dass die Rollen und damit die je zugehörigen Schienen regelmässig seitlich gegeneinander versetzt sind. Somit verlaufen die Kettenrollen mit der Kettenrollenschiene in einer seitlichen Ebene meist recht weit außen, während die Stützrollen auf einer anderen seitlichen Ebene laufen, meist einwärts versetzt. Dies bedingt andererseits, dass durch diesen seitlichen Versatz die erforderliche Baubreite der Fahrtreppe oder des Fahrsteigs in seitlicher Richtung zunimmt.The support of the steps of escalators and the pallets of moving walkways usually takes place via chain rollers and support rollers, which run on each associated rails. In the return, the steps or pallets must be transported upside down, and at the ends of the moving walk or the escalator must ever be made a diversion. This requires that the rollers and thus the respective associated rails are regularly laterally offset from each other. Thus, the chain rollers run with the chain roller rail in a lateral plane usually quite far outside, while the support rollers run on a different lateral plane, usually offset inwardly. On the other hand, this requires that the required width of the escalator or moving walk in the lateral direction increases due to this lateral offset.

Um dies zu vermeiden, ist es seit langem bekannt, die Rollen und damit die zugehörigen Schienen mindestens teilweise unterhalb der Stufen oder Paletten verlaufen zu lassen. Dies bedingt andererseits eine vergrößerte Bauhöhe der Fahrtreppe oder des Fahrsteigs, die signifikant ausfällt, da die betreffende Fahrtreppe oder der betreffende Fahrsteig dann sowohl hinsichtlich des Vorlaufs als auch hinsichtlich des Rücklaufs in der Bauhöhe erhöht werden muss. Diese Maßnahme läuft insofern dem Bestreben nach einer schlanken Ausgestaltung der Fahrtreppe, insbesondere im Bereich des Rahmens, entgegen.To avoid this, it has long been known to let the rollers and thus the associated rails run at least partially below the steps or pallets. On the other hand, this requires an increased height of the escalator or moving walk, which turns out to be significant, since the escalator or the relevant moving walkway must then be increased in terms of both the lead and in terms of return in height. This measure runs contrary to the desire for a slim design of the escalator, especially in the area of the frame, contrary.

Um eine reduzierte Baubreite zu erzielen, ohne insofern eine erhöhte Bauhöhe in Kauf zu nehmen, ist es beispielsweise bereits aus der DE-OS-23 42 849 bekannt geworden, die Kettenrollen knapp neben der betreffenen Stufe vorzusehen. Auch hier muss selbstverständlich die erforderliche Umlenkung des Laufs des Stufenbandes realisiert werden, und der Rücklauf erfordert auch hier den Transport des Stufenbandes in umgekehrter Position.To achieve a reduced width, without taking into account an increased height, it is for example already out of the DE-OS-23 42 849 became known to provide the chain rollers just next to the relevant stage. Again, of course, the required deflection of the barrel of the step band must be realized, and the return requires here also the transport of the step band in the reverse position.

Um eine schlanke Ausgestaltung der Fahrtreppe bei geringer Baubreite zu realisieren, ist es auch bereits vorgeschlagen worden, den Rahmen der Fahrtreppe möglichst schlank und knapp an den Fahrtreppenschienen zu realisieren. Beispielsweise kann bei Rahmenkonstruktionen mittels Fachwerk eine bei vergleichsweise geringem Materialeinsatz steife und durchbiegungsfeste Abstützung gewährleistet sein.In order to realize a slim design of the escalator with a small width, it has also been proposed to realize the frame of the escalator as slim as possible and close to the escalator rails. For example, in frame structures by means of a truss with a comparatively low material use stiff and deflection-resistant support can be ensured.

Eine derartige Lösung ermöglicht zwar eine vergleichsweise kompakte Rahmenbauweise, wobei dennoch die Baubreite oder die Bauhöhe - je nach gewählter Anordnung der Kettenrollen bzw. Stützrollen - vergleichsweise gross ist.Although such a solution allows a relatively compact frame construction, yet the width or height - depending on the selected arrangement of the chain rollers or support rollers - is relatively large.

Daher liegt der Erfindung die Aufgabe zugrunde, eine Fahrtreppe oder einen Fahrsteig gemäss dem Oberbegriff von Anspruch 1 zu schaffen, der hinsichtlich der Bauhöhe und Baubreite gegenüber den bekannten Lösungen verbessert ist, ohne dass Einbußen hinsichtlich der Betriebssicherheit der Fahrtreppe oder des Fahrsteigs in Kauf genommen werden müssen.The invention is therefore an object of the invention to provide an escalator or a moving walk according to the preamble of claim 1, which is improved in terms of height and width compared to the known solutions, without sacrificing the reliability of the escalator or moving walk in purchasing have to.

Erfindungsgemäss besonders günstig ist es, dass sich durch eine besondere Anordnung der Kettenrollen die Vorteile der bislang alternativen Anordnungen, also entweder unterhalb oder seitlich der Stufen bzw. Paletten, kombinieren lassen:

  • Die Kettenrolle ist am Übergang zwischen Unterseite und Seiten-fläche der betreffenden Stufe oder Palette angeordnet, und zwar so, dass sie sowohl seitlich als auch zur Unterseite hin je etwas die Stufe oder Palette überragt. Unterseite bezieht sich hier auf den normalen Zustand, also den Zustand der Stufe oder Palette, bei der die Trittfläche oben ist. Diese Anordnung erlaubt es überraschend mit einfachen Mitteln, trotz der vollen Belastbarkeit eine kompaktere Ausgestaltung zu realisieren: Im Vorlauf seht die gesamte Breite der Stützrolle für die Abstützung zur Verfügung, und die Stützrollenschiene kann entsprechend breit realisiert sein. Dies ermöglicht es auch, die erwünschte seitliche Toleranz bereitzustellen, so dass die Breite der Vorlauf-Kettenrollenschiene beispielsweise doppelt so gross wie die Breite der Kettenrolle sein kann und die Kettenrolle eine recht breite Bahn für ihr Ablaufen vorfindet.
According to the invention, it is particularly favorable that the advantages of the hitherto alternative arrangements, ie either below or laterally of the steps or pallets, can be combined by a special arrangement of the chain rollers:
  • The chain roller is located at the transition between the underside and side surface of the respective step or pallet, in such a way that it projects slightly beyond the step or pallet both laterally and towards the bottom. Bottom refers here on the normal state, that is the state of the step or pallet, where the tread is on top. This arrangement allows surprisingly simple means, in spite of the full load capacity to realize a more compact design: In the run see the entire width of the support roller for the support available, and the support roller rail can be realized correspondingly wide. This also makes it possible to provide the desired lateral tolerance, so that the width of the forward chain roller rail, for example, can be twice as large as the width of the chain roller and the chain roller finds a fairly wide path for their drainage.

Erfindungsgemäss ist es vorgesehen, für den - von Fahrgästen und weiteren Gewichten unbelasteten - Rücklauf der Stufen oder Paletten lediglich einen äusseren Teil der Kettenrolle zu verwenden. Die Baubreite der Fahrtreppe lässt sich durch diese Maßnahme deutlich reduzieren, zumal eine entsprechende Reduktion der Baubreite erfindungsgemäss beidseitig vorgesehen sein kann.According to the invention, it is intended to use only an outer part of the chain roller for the return of the steps or pallets, which is unloaded by passengers and other weights. The width of the escalator can be significantly reduced by this measure, especially since a corresponding reduction of the width can be provided according to the invention on both sides.

Dennoch ist der Umlenkbereich der erfindungsgemässen Fahrtreppe zwanglos zu realisieren, wobei die Stützrollenschiene für den Vorlauf mindestens bis zum Bereich der Kammplatte in voller Breite und unterhalb der Stufe oder Palette vorgesehen sein kann.Nevertheless, the deflection of the inventive escalator is to realize casual, the support roller rail for the flow can be provided at least to the area of the comb plate in full width and below the step or pallet.

Für den Rücklauf-Transport der Stufe oder Palette reicht die Abstützung auch auf etwa der Hälfte der Breite der Stützrolle aus, und die Bauhöhe der erfindungsgemässen Fahrtreppe oder des erfindungsgemässen Fahrsteigs entspricht praktisch einer Lösung mit sich seitlich erstreckenden Kettenrollen und Stützrollen.For the return transport of the step or pallet, the support also extends to about half the width of the support roller, and the height of the inventive escalator or the moving walkway according to the invention corresponds in practice to a solution with laterally extending chain rollers and support rollers.

Weitere Vorteile, Einzelheiten und Merkmale ergeben sich aus der nachfolgenden Beschreibung zweier Ausführungsbeispiele der Erfindung anhand der Zeichnung.Further advantages, details and features will become apparent from the following description of two embodiments of the invention with reference to the drawing.

Es zeigen:

Fig. 2
a modified embodiment of the inventive escalator, in a Fig. 1 corresponding representation.

Eine erfindungsgemässe Fahrtreppe 10 weist Fahrtreppenstufen auf, von denen eine Fahrtreppenstufe 12 in Fig. 1 dargestellt ist. Jede Stufe weist an jeder Seite je eine Stützrolle 14 und eine Kettenrolle 16 auf, die je auf Achsstummeln gelagert sind. Der Achsstummel 18 der Kettenrolle 16 ist aus Fig. 1 ersichtlich, während der betreffende Achsstummel der Stützrolle 14 durch die Darstellung der Stufe 12 verdeckt ist und lediglich durch die schematisch eingezeichnete Achse 20 der Stützrolle 14 angedeutet ist.An escalator 10 according to the invention has escalator steps, one of which is an escalator step 12 in FIG Fig. 1 is shown. Each stage has on each side depending on a support roller 14 and a chain roller 16, which are each mounted on stub axles. The stub axle 18 of the chain roller 16 is off Fig. 1 can be seen while the respective stub axle of the support roller 14 is covered by the representation of the stage 12 and is indicated only by the schematically drawn axis 20 of the support roller 14.

Die Kettenrolle 16 ist in an sich bekannter Weise über eine Kettenrollenschiene 22 gelagert. Die Kettenrollenschiene 22 erstreckt sich seitlich recht weit aussen und weist eine beliebige Breite auf, und ist insbesondere deutlich breiter als die Kettenrolle 16. Die Kettenrolle 16 ist in der Situation gemäss Fig. 1 auf der inneren Hälfte, also der der Stufe 12 zugewandten Hälfte, der Schiene 22 abgestützt.The chain roller 16 is mounted in a conventional manner via a chain roller rail 22. The chain roller rail 22 extends laterally quite far outside and has any width, and in particular is significantly wider than the chain roller 16. The chain roller 16 is in the situation according to Fig. 1 on the inner half, that is the stage 12 facing half, the rail 22 supported.

Die Stützrolle 14 springt gegenüber der Fahrtreppenstufe 12 - in der hängenden Darstellung gemäss Fig. 1 - etwas vor, beispielsweise um etwa ein Zehntel ihres Durchmessers. Die Stützrolle 14 ist so gelagert, dass sie in der in Fig. 1 dargestellten Vorderansicht der Fahrtreppenstufe 12 diese großflächig überlappt, beispielsweise über mehr als ein Drittel, wobei das Überlappungsmaß im Extremfall auch etwas mehr als die Hälfte der Fläche der Stützrolle 14 - in der Ansicht gemäss Fig. 1 - betragen kann.The support roller 14 jumps opposite the escalator step 12 - in the hanging view according to Fig. 1 - something in front, for example, about one tenth of its diameter. The support roller 14 is mounted so that it in the in Fig. 1 illustrated front view of the escalator stage 12 overlaps this over a large area, for example over more than a third, wherein the overlap in extreme cases, slightly more than half of the surface of the support roller 14 - in the view Fig. 1 - may amount.

Die Stützrolle 14 ist erfindungsgemäss auf einer Stützrollenschiene 26 abgestützt, die sich seitlich neben der Fahrtreppenstufe 14 erstreckt. Die Abstützung erfolgt jedoch so, dass lediglich ein Teil der Stützrolle 14 im Rücklauf abgestützt ist, beispielsweise etwa die äussere Hälfte der Stützrolle 14. Dies ermöglicht es, eine insgesamt deutlich schmalere Stützrollenschiene 26 zur Verfügung zu stellen. Damit kann auch die Kettenrollenschiene 22 weiter einwärts, also zur Fahrtreppenstufe 12 hin verlagert, angeordnet werden, so dass die Baubreite der Konstruktion gegenüber den bekannten seitlich gelagerten Fahrtreppenstufen deutlich sinkt.The support roller 14 is according to the invention supported on a support roller rail 26, which is located laterally next to the escalator step 14 extends. The support is, however, such that only a part of the support roller 14 is supported in the return, for example, about the outer half of the support roller 14. This makes it possible to provide an overall much narrower support roller rail 26. Thus, the chain roller rail 22 further inward, so moved to the escalator step 12 out, are arranged so that the width of the construction compared to the known laterally mounted escalator steps drops significantly.

Die Schienen 22 und 26 können in beliebiger geeigneter Weise realisiert sein. Eine weitere Möglichkeit der Realisierung ist in der Ausführungsform gemäss Fig. 2 ersichtlich. Dort ist die Stützrollenschiene 26 als L-Profil realisiert, wobei der senkrechte Schenkel des L sich benachbart der Mittenachse 28 der Stützrolle erstreckt. Auch die Kettenrollenschiene 22 ist in ihrer Breite vermindert. Sie ist als T-Profil ausgebildet, wobei der waagrechte Schenkel die Lauffläche für die Kettenrolle 16 bildet. Durch die Abstützung durch die vertikalen Schenkel lässt sich erforderliche Stabilität bei dieser Ausführungsform für beide Schienen 22 und 26 gewährleisten.The rails 22 and 26 can be realized in any suitable manner. Another possibility of implementation is in the embodiment according to Fig. 2 seen. There, the support roller rail 26 is realized as an L-profile, wherein the vertical leg of the L extends adjacent to the center axis 28 of the support roller. The chain roller rail 22 is reduced in width. It is designed as a T-profile, wherein the horizontal leg forms the running surface for the chain roller 16. The support provided by the vertical legs ensures required stability in this embodiment for both rails 22 and 26.
