Abstract

Escalator, comprising a step band consisting of one-piece steps, which can also be installed in standard escalators, wherein the substructure of the steps is designed so that this allows a deflection of the steps close to the step center and also another guide element directly, such as a Axis, as with the other rollers, record. Due to the adapted substructure of the steps, optimized with an additional guide in the deflection and an adapted deflection of the steps to divert them around the center, the height of an escalator in the horizontal area by the construction height of the individual stages and the height of the tread determined by middle leadership. Depending on the type of drive, an adapted gearbox with a rigid eccentric deflection axis can be executed. For a more optimal travel in the deflection region, the guide elements can advantageously be made in two parts in order to ensure a smooth, constraint-free travel in the deflection region, which results in a three-point bearing in cooperation with the chain roller.

Description

The invention describes an escalator for passenger transport, a deflection area, an escalator step, and a transmission with the aim of reducing the height.

The common escalators have both in the horizontal and in the inclined area a relatively large height between the lower roller shutter support / cover and upper edge staircase on. This is necessary so that the steps without collision and constraint pass through the deflection area and can be safely guided in the forward and reverse.

In PCT / EP08 / 62965 ( US 20100282570A1 ) and PCT / EP00 / 03672 ( WO 00/66476 ) steps for an escalator are shown, which meet the requirements for a reliable operation of an escalator, as described above. These are stages that are immutable in their geometric shape, such as one-piece cast-made stages, in operation. 5a shows such a stage, which is an example of the prior art.
This construction form of steps, with invariably geometric shape in operation, has a high reliability, while a robust design, on.

In DE 102005058051B3 is an escalator with collapsible, self-contained steps, with geometrically variable in operation form, with reduced height, described. This design is characterized by complex deflection areas and a large number of moving parts and is thus more maintenance-intensive and less robust.

Likewise, in EP 1 072 552 A1 Escalators with folding steps in various designs and with one-piece steps according to the paternoster principle, with the aim of reducing the height, described. The flow and return of the collapsible stages takes place here after the circulation or after the paternoster principle.
These designs also represent a prior art, but the reduction in height is accompanied by increased mechanical complexity and, insofar as it is not immutable in their geometric shape, such as one-piece stages, with a loss of robustness.

In EP 1 338 548 A1 an escalator is described with one-piece steps and reduced height. By a further leadership role, the roller of the stage is guided in the deflection around the deflection axis, wherein there is still a large distance between forward and backward stages, among other things determined by the deflection axis. The guide roller sits on a support arm which has to absorb high torsional forces and bending moments and does not represent a simple, robust solution. The resulting starting angle between the axis sprocket and additional roller and additional guidance in the deflection is quite large in some areas. Furthermore, the guide rollers were moved at the start behind the step edge, which has a negative effect on the ride comfort by tilting when shifting the weight of a user.

The aim of the invention is to reduce the overall height of an escalator in the horizontal as well as inclined part, while maintaining a non-changing its geometric shape stage, such as a one-piece step produced by the casting process, substantially. The design of the steps and the escalator should be characterized by low mechanical complexity, robust, low-maintenance and compatible, or be partially compatible with existing systems. In addition, the usual simple components in mechanical engineering, with high availability are used.

Another object of the invention is that a combination with the reinforced robust designs is possible, so that only there a reduced height is used where this is also needed, either in the upper or lower, or both horizontal areas of the escalator.

For an escalator with steps, which maintain their geometric shape during operation of the escalator, such as one-piece steps produced by casting, this is achieved by at least one roller in the lower part, at least one roller in the region of the step per step on a given path , below the level of the same caster in the horizontal area of the guide, for the downstairs stages, in the deflection process in height down to let the steps more closely deflected around their own center. For an upper deflection, the movement is mirrored upward, with the roller is guided upward.

The substructure of a step is to be adapted for the correspondingly narrower circulation in their geometric shape so that the steps pass through the reversing device without contact. The steps are adjusted so that they can also be installed in conventional escalators.

In the associated subclaims optimized developments of the stage according to the invention are described.

The reduction in height with the assemblies described above is limited by the space required for the guide in the deflection and the larger angle, which forms between the line of the rollers and the guide. As the angle increases, the running properties of the roller are reduced.

By another guide element directly connected to the substructure of the step, e.g. a roller, and an associated optimized guide in the deflection, give a very small angle between the axis drive chain / additional guide and additional guide element. The resulting orbit for the rollers can be performed well beyond the limit described above for the necessary guidance for these into the orbit of the chain drive rollers.

In the appended subclaims optimized developments of the additional guide according to the invention and corresponding guide element of the stage are described.

Due to the described design of an escalator, the steps and design of the deflection, the height can be significantly reduced, along with robustness, simple constructive implementation and compatibility with existing escalator systems.

Thus, the described implementation of an escalator and its sub-elements for a variety of drive modules, modular, external and internal. For internal only for the deflection which has no drive unit.

For systems equipped with deflection axles, they must be replaced by rigid eccentrically arranged axles if the maximum height reduction is to be achieved. The rollers of the forward and backward stages in the deflection then have only the distance of a shared tread. It can thus be the same reduction in height achieved for escalators that work on the paternoster principle, but require more complex, less robust deflection, and in which possibly necessary sprockets can not be performed on a common axis.

With the use of sprockets they are stored according to a rigid axis and synchronized, with external drive module, via a gearbox. The power transmission can be done on one side in the middle or on both sides of the upstream drive axle.

Also, the gear units for the handrails are to be arranged laterally, if you want to achieve the maximum reduction in height. At the same time shortens due to the smaller deflection radius, the step band and the associated number of steps compared to a conventional escalator for the same floor height to be overcome.

In the perspective diagram, an escalator with external drive modules is shown, in which the rollers of the forward and backward stages in the horizontal areas only at a distance of the shared tread from each other.

The robust design described here in the invention allows a substantial reduction of the height between the flight of stairs and escalator underside, especially in the horizontal deflection, escalators with integral steps, while partial compatibility with parts in use escalators of the same basic type. This enables the parallel operation of the designs with uniform spare parts provision.

The reduced height allows architectural integration in ceiling elements and false ceilings, especially in public buildings such as shopping centers, hotel complexes and airports.

Often the lower escalator areas also determine subsequent drainage facilities and whole, depending, floor heights up to the choice of drainage systems and corresponding pump systems. In some cases, such pump systems can be completely dispensed with and can be dispensed with by means of drainage lines let into the bottom plate, which are fed to a central pumping device.

The low height allows for appropriate conditions and the subsequent installation in existing buildings.

The drawings show the invention in various application examples and details.

• 1: Skizze eines unteren Umlenkbereiches einer Rolltreppe mit reduzierter Bauhöhe. Die Skizzen 1a) bis 1d) stellen den Umlauf der Stufen im Umlenkbereich dar. Sie zeigen wie das Führungselement/Laufrolle 12/22 der Führung 9, hier ein Führungsprofiel, folgt und dabei eine Führungsbahn 10 beschreibt, welche mit zunehmender Drehung der Stufe erst nach unten ausgelenkt wird und anschließend in einer gegenläufigen Kurvenbewegung umgelenkt, beziehungsweise in gegengesetzter Abfolge, je nach Laufrichtung der Rolltreppe. Die Führungen 8 für den Vor- und Rücklauf können somit zusammenrücken. Die Bauhöhe h2 wird somit durch die Bauhöhe der einzelnen Stufen 14 bestimmt. Bei maximaler Zusammenführung der Führungen 8 für Vor- und Rücklauf können keine Teile des Antriebsmechanismus mehr innerhalb des umlaufenden Stufenbandes liegen. In diesem Fall kann ein Antriebsmechanismus nach 15 zur Anwendung kommen, in Verbindung des hier dargestellten Kettenrades, oder ein modularer Antrieb im geneigten Teil der Rolltreppe. Bei einer solchen Anwendung kann das Kettenrad durch die ebenfalls gepunktet dargestellte Führung 7 für das Führungselement/Laufrolle 11/21 ersetzt werden. Zu beachten ist hierbei der sich einstellende Winkel 25 zwischen der gedachten Line der beiden Laufrollen 11/21, 12/22 und der Führung 9. Mit kleiner werdendem Umlenkradius wird dieser Winkel 25 größer und die wirkenden Kräfte verlagern sich mehr in Richtung Führungswandung anstelle in Richtung der Bewegungsbahn 10. Große Winkel setzen sehr gute Laufeigenschaften der Führungselement/Laufrolle 12/22 voraus um Zwängungen zu vermeiden. Die Anordnung von Auftritt, Antritt, Laufrolle und Kettenrolle zueinander entsprechen denen einer Stufe wie sie auch bei typischen Rolltreppen ohne reduzierte Bauhöhe zum Einsatz kommen.
• 2: Skizze eines unteren Umlenkbereiches einer Rolltreppe mit reduzierter Bauhöhe. Die Skizzen 2a) bis 2d) stellen den Umlauf der Stufen im Umlenkbereich dar. Da die Bauhöhe direkt von der Bauhöhe der einzelnen Stufe abhängig ist, wurde diese im Bereich der Laufrolle angepasst. Zu beachten ist hierbei der sich teilweise einstellende sehr große Winkel 25 zwischen der gedachten Line der beiden Laufrollen 11/21, 12/22 und der Führung 9. Mit kleiner werdendem Umlenkradius geht dieser Winkel 25 bis ca. 75° und die wirkenden Kräfte verlagern sich stark in Richtung Führungswandung anstelle in Richtung der Bewegungsbahn 10. So große Winkel 25 setzen sehr gute Laufeigenschaften der Führungselement/Laufrolle 12/22 voraus um Zwängungen zu vermeiden. Die Reduktion der Bauhöhe h1-h2 fällt entsprechen deutlich aus.
• 3: Skizze eines unteren Umlenkbereiches einer Rolltreppe mit reduzierter Bauhöhe. Die einzelnen Stufen wurden im Bereich der Laufrolle optimiert für eine Rolltreppe mit einer Neigung von 30° angepasst. Hierbei ist die Laufrolle nach wie vor dem Auftritt angeordnet. Die Zwängungen wie in 2 beschrieben sind aber nur noch durch extrem gute Laufeigenschaften der Laufrollen beherrschbar und somit aber keine robuste Ausführung.
• 4: Skizze eines Umlenkbereiches einer typischen Rolltreppe, entsprechend dem Stand der Technik. Die Darstellung zeigt auch den sehr geringen Abstand der Stufen untereinander im Umlenkbereich.

Die Stufen nach 5a und 5b unterscheiden sich hierbei nur in der Unterkonstruktion 16 der Stufe und Stufen mit angepasster Unterkonstruktion 16 nach 5b sind somit für herkömmliche Rolltreppen als auch für Rolltreppen mit reduzierter Bauhöhe geeignet.
• 6, einschließlich der 6a bis 6c, zeigen die entsprechenden Stufen nach 5 einschließlich des zusätzlichen, direkt durch die Unterkonstruktion 16 aufgenommene, Führungselements 30.

Die Darstellung zeigt die Lage der Trägerachse für die zusätzliche Führung/Laufrolle 30 unterhalb der seitlichen Verkleidung/Sockelverkleidung, und direkt in der Unterkonstruktion 16 der Stufe eingebunden. In 7e sind die Stufen 5a und 6b überlagert dargestellt.
• 8 zeigt eines Umlenkbereiches einer typischen Rolltreppe, entsprechend dem Stand der Technik, ausgerüstet mit Stufen nach 5b. Die Darstellung verdeutlicht auch den weiten Anstand zwischen den einzelnen Stufen durch die angepasste Unterkonstruktion 16 der einzelnen Stufen 14 im Vergleich zu 4
• 9 zeigt einen Umlenkbereich mit Stufen 14 nach 5c, mit angepasster Unterkonstruktion 16, und einem typischen, den Stand der Technik entsprechendem umlauf um eine beweglich Achse, auf den die Kettenräder montiert sind. Bereits der Einsatz von Stufen mit angepasster Unterkonstruktion erlaubt eine Reduktion der Bauhöhe einer Rolltreppe im horizontalen Bereich.
• 10 Skizze eines unteren Umlenkbereiches einer Rolltreppe mit reduzierter Bauhöhe. Die Skizzen 10a) bis 10d) stellen den Umlauf der Stufen im Umlenkbereich dar. Sie zeigen wie das Führungselement/Laufrolle 12/22 eine Führungsbahn 10 beschreibt, wie in 1 auch dargestellt. Im Gegensatz zu 1 erfolgt die Führung über ein zusätzliches Führungselement/Laufrolle 30/31, welche direkt in die Unterkonstruktion der Stufe integriert ist und ohne Tragarme auskommt, und Führung. Bei maximaler Zusammenführung der Führungen 8 für Vor- und Rücklauf können keine Teile des Antriebsmechanismus mehr innerhalb des umlaufenden Stufenbandes liegen. In diesem Fall kann ein Antriebsmechanismus nach 15 zur Anwendung kommen, in Verbindung des hier dargestellten Kettenrades, oder ein modularer Antrieb im geneigten Teil der Rolltreppe. Bei einer solchen Anwendung kann das Kettenrad durch die ebenfalls gepunktet dargestellte Führung 7 für das Führungselement/Laufrolle 11/21 ersetzt werden. Zu beachten ist hierbei der sich einstellende Winkel 25 zwischen der gedachten Line der beiden Laufrollen 11/21, 30/31 und der Führung 29. Durch die zusätzliche Führung kann dieser optimal eingestellt werden und die wirkenden Kräfte verlagern sich nicht mehr in Richtung Führungswandung sondern in die durch die Führung 29 vorgegeben Richtung. Die kleinen Winkel garantieren optimale Laufeigenschaften der Führungselement/Laufrolle 12/22 und Zwängungen wie in 1 beschrieben werden vermieden. Die Anordnung von Auftritt, Antritt, Laufrolle und Kettenrolle zueinander entsprechen denen einer Stufe wie sie auch bei typischen Rolltreppen ohne reduzierte Bauhöhe zum Einsatz kommen.
• 11 zeigt die in 2 dargestellte Skizze nach dem gleichen Ansatz wie in 10 beschrieben. Zu beachten ist hierbei der sich einstellende Winkel 25 zwischen der gedachten Line der beiden Laufrollen 11/21, 30/31 und der Führung 29. Durch die zusätzliche Führung kann dieser auch bei kleineren Umlenkradien optimal eingestellt werden und die wirkenden Kräfte verlagern sich nicht mehr in Richtung Führungswandung sondern in die durch die Führung 29 vorgegeben Richtung. Die kleinen Winkel garantieren optimale Laufeigenschaften der Führungselement/Laufrolle 12/22 und Zwängungen wie in 2 beschrieben werden vermieden.
• 12, 12a bis 12d, zeigt die in 3 dargestellte Skizze nach dem gleichen Ansatz wie in 10. beschrieben. Der sich einstellende Winkel 25 zwischen der gedachten Line der beiden Laufrollen 11/21, 30/31 und der Führung 29 kann durch die zusätzliche Führung auch bei sehr kleinen Umlenkradien optimal eingestellt werden und die wirkenden Kräfte verlagern sich in die durch die Führung 29 vorgegeben Richtung. Die kleinen Winkel garantieren optimale Laufeigenschaften der Führungselement/Laufrolle 12/22 und Zwängungen wie in 2 beschrieben werden vermieden.

• 14 zeigt eine geteilte Führungsrolle 30. Durch die entsprechende Ausführung der Führung 29 durchlaufen die beiden Führungsrollen 30 gegenläufig im Umlenkbereich. Somit wird auch im Umlenkbereich eine Dreipunktführung gewährleistet. Die Ausbildung gewährleitet einen optimalen und auch ruhigen Lauf im Umlenkbereich. Dass bei einigen Rolltreppen typisch Klapp-Geräusch wird vermieden. Eine solche Ausbildung lässt sich auch bei den Laufrollen und Führungen typische Rolltreppen umsetzen.

The illustrations include:

• 1 : Sketch of a lower deflection area of an escalator with reduced height. The sketches 1a ) to 1d) represent the circulation of the steps in the deflection region. They show how the guide element / roller 12/22 of the guide 9, here a guide profile, follows and thereby describes a guideway 10, which with increasing rotation of the stage only after deflected down and then deflected in an opposite curve movement, or in opposite order, depending on the direction of the escalator. The guides 8 for the flow and return can thus move together. The height h2 is thus determined by the height of the individual stages 14. At maximum merge of the guides 8 for flow and return no parts of the drive mechanism can be more within the revolving step band. In this case, a drive mechanism after 15 be used in conjunction with the sprocket shown here, or a modular drive in the inclined part of the escalator. In such an application, the sprocket can be replaced by the also shown dotted guide 7 for the guide element / roller 11/21. It should be noted here is the adjusting angle 25 between the imaginary line of the two rollers 11/21, 12/22 and the guide 9. With decreasing radius of deflection, this angle 25 is greater and the acting forces shift more towards the guide instead of in the direction The trajectory 10. Large angles require very good running properties of the guide element / roller 12/22 ahead to avoid constraints. The arrangement of appearance, start, roller and chain roller to each other correspond to those of a stage as they are used in typical escalators without reduced overall height.
• 2 : Sketch of a lower deflection area of an escalator with reduced height. The sketches 2a ) to 2d) represent the circulation of the steps in the deflection area. Since the overall height depends directly on the height of the individual steps, this was adapted in the area of the roller. It should be noted here is the partially adjusting very large angle 25 between the imaginary line of the two rollers 11/21, 12/22 and the guide 9. With decreasing deflection this angle is 25 to about 75 ° and the forces are shifting strong in the direction of the guide wall instead of in the direction of the trajectory 10. Such large angles 25 require very good running properties of the guide element / roller 12/22 in order to avoid constraints. The reduction in the height h1-h2 is correspondingly clear.
• 3 : Sketch of a lower deflection area of an escalator with reduced height. The individual steps were optimized in the area of the roller for an escalator with a slope of 30 ° adapted. Here, the roller is still arranged the appearance. The constraints like in 2 but are described only by extremely good running properties of the rollers manageable and thus not a robust design.
• 4 : Sketch of a deflection of a typical escalator, according to the prior art. The illustration also shows the very small distance of the steps between each other in the deflection area.
• 5 : One-piece step for an escalator. 5a shows a typical one-piece stage according to the prior art. 5b to 5d show one-piece steps with modular attachments 33 for the guide rollers 22 with a corresponding reduced height for the single stage to achieve an optimal reduction in the height of the deflection of an escalator. The steps after 5a and 5b differ only in the substructure 16 of the stage and stages with adapted substructure 16 after 5b are therefore suitable for conventional escalators as well as for escalators with reduced height.
• 6 , including the 6a to 6c , show the corresponding steps 5 including the additional, directly received by the substructure 16, guide member 30th
• 7 , the 7a to 7d show the corresponding steps 5 and 6 on a 30 ° inclined track. The illustration shows the position of the support axis for the additional guide / roller 30 below the side panel / base panel, and incorporated directly into the substructure 16 of the stage. In 7e are the steps 5a and 6b superimposed.
• 8th shows a deflection of a typical escalator, according to the prior art, equipped with steps 5b , The illustration also illustrates the wide decency between the individual stages by the adapted substructure 16 of the individual stages 14 in comparison to 4
• 9 shows a deflection with steps 14 after 5c , with adapted substructure 16, and a typical, according to the prior art circulation around a movable axis on which the sprockets are mounted. Even the use of steps with adapted substructure allows a reduction in the height of an escalator in the horizontal area.
• 10 Sketch of a lower deflection area of an escalator with reduced height. The sketches 10a ) to 10d) represent the circulation of the steps in the deflection region. They show how the guide element / roller 12/22 describes a guide track 10, as in FIG 1 also shown. In contrast to 1 the guide is via an additional guide element / roller 30/31, which is integrated directly into the substructure of the stage and manages without support arms, and leadership. At maximum merge of the guides 8 for flow and return no parts of the drive mechanism can be more within the revolving step band. In this case, a drive mechanism after 15 be used in conjunction with the sprocket shown here, or a modular drive in the inclined part of the escalator. In such an application, the sprocket can be replaced by the also shown dotted guide 7 for the guide element / roller 11/21. It should be noted here is adjusting angle 25 between the imaginary line of the two rollers 11/21, 30/31 and the guide 29. By the additional guide this can be optimally adjusted and the forces acting no longer shift in the direction of the guide wall but in the direction given by the guide 29. The small angles guarantee optimum running characteristics of the guide element / roller 12/22 and restraints as in 1 be avoided. The arrangement of appearance, start, roller and chain roller to each other correspond to those of a stage as they are used in typical escalators without reduced overall height.
• 11 shows the in 2 illustrated sketch according to the same approach as in 10 described. It should be noted here is the adjusting angle 25 between the imaginary line of the two rollers 11/21, 30/31 and the guide 29. Due to the additional guide this can be optimally adjusted even with smaller deflection radii and the forces do not shift in Direction guide wall but in the direction indicated by the guide 29 direction. The small angles guarantee optimum running characteristics of the guide element / roller 12/22 and restraints as in 2 be avoided.
• 12 . 12a to 12d , shows the in 3 illustrated sketch according to the same approach as in 10 , described. The self-adjusting angle 25 between the imaginary line of the two rollers 11/21, 30/31 and the guide 29 can be optimally adjusted by the additional guide even at very small deflection radii and the forces acting shift in the direction predetermined by the guide 29 , The small angles guarantee optimum running characteristics of the guide element / roller 12/22 and restraints as in 2 be avoided.
• 13 shows the steps running back and forth in the horizontal area of an escalator. The height is determined by the height of the step and the height of the guide 8. The sketch also shows the self-adjusting Dreipunktfuhrung the stage between the guide elements / rollers 21, 22, 30th
• 14 shows a split guide roller 30. By the corresponding design of the guide 29 through the two guide rollers 30 in opposite directions in the deflection. Thus, a three-point control is guaranteed even in the deflection. The training ensures optimal and quiet running in the deflection area. That with some escalators typical folding noise is avoided. Such training can be implemented even with the rollers and guides typical escalators.
