Description

Die Erfindung betrifft eine Rolltreppe mit einer Mehrzahl verfahrbarer Stufensegmente, die aneinandergereiht jeweils auf vier Rädern laufen, die an den vier Ecken jedes Stufensegments gelagert sind, wobei die Trittfläche jedes Stufensegments beim vorderseitigen Transport waagerecht und beim rückseitigen Rücktransport schräg abfallend liegt.The invention relates to an escalator with a plurality of movable step segments, which run in a row on four wheels which are mounted on the four corners of each step segment, the tread of each step segment lying horizontally during transport at the front and sloping downwards during transport backwards.

Aus der JP 2003292276A ist eine Rolltreppe bekannt, bei der die Stufensegmente aus mehreren Profilen bestehen die aneinander angelenkt sind, wobei sowohl die vorderen Rollen/Räder der Stufensegmente an einer Transportkette als auch die hinteren Rollen/Räder der Stufensegmente an einer weiteren Transportkette befestigt sind. Eine solche Rolltreppenkonstruktion ist technisch aufwendig und zeigt darüber hinaus den Nachteil, den übliche Rolltreppen auch haben, dass sowohl im unteren Endbereich (untere Wendestation) als auch im oberen Endbereich (obere Wendestation) eine große Bauhöhe erforderlich ist, so dass ein Einbau dieser Rolltreppe dann nicht möglich ist, wenn im unteren und/oder oberen Endbereich wenig Bauhöhe zur Verfügung steht.From the JP2003292276A an escalator is known in which the step segments consist of several profiles which are hinged to one another, with both the front rollers/wheels of the step segments being attached to a transport chain and the rear rollers/wheels of the step segments being attached to another transport chain. Such an escalator construction is technically complex and also has the disadvantage that conventional escalators also have, that both in the lower end area (lower turning station) and in the upper end area (upper turning station), a large overall height is required, so that an installation of this escalator is then possible is not possible if little height is available in the lower and/or upper end area.

DE 10 2005 058 052 A1 zeigt eine Rolltreppe, bei der jeder Stufenkörper eine erhebliche Höhe aufweist. Bei dieser Konstruktion weist die Rolltreppe sowohl im unteren als auch im oberen Endbereich eine große Bauhöhe auf, so dass die Rolltreppe nicht dort eingebaut oder verwendet werden kann, wo geringe Bauhöhen erforderlich sind. Dies ist insbesondere bei den Treppen von Bedeutung, mit denen auf Flugplätzen die Passagiere in die Flugzeuge gebracht werden. DE 10 2005 058 052 A1 shows an escalator in which each step body has a significant height. With this construction, the escalator has a large overall height both in the lower and in the upper end area, so that the escalator cannot be installed or used where low overall heights are required. This is particularly important in the case of the stairs used to bring passengers onto the aircraft at airports.

Die DE 20 2007 003 908 U1 zeigt ein Personenförderungsband, mit dem Personen waagerecht transportiert werden. Ein solches Beförderungsband weist keine Stufen auf und transportiert mit waagerechten Platten Personen und hat damit auch keine Umlenkungsprobleme an den Enden des Beförderungsbandes.The DE 20 2007 003 908 U1 shows a passenger conveyor belt with which people are transported horizontally. Such a conveyor belt has no steps and transports people with horizontal plates and therefore has no deflection problems at the ends of the conveyor belt.

Die in der GB 197 744 A gezeigten Lösung weisen die Stufenkörper eine erhebliche Höhe auf, da hier die Konstruktion nur funktioniert, wenn an der Unterseite jeder Stufenplatte ein großer Vorsprung vorsteht, an dessen Unterseite die Rollen befestigt sind. An den Umwendestellen kann keine geringe Bauhöhe erreicht werden.The one in the GB 197 744 A The solution shown, the step bodies have a considerable height, since the construction only works here if a large projection protrudes from the underside of each step plate, on the underside of which the rollers are attached. At the turning points, it is not possible to achieve a low overall height.

Bei der in der WO 99/52 808 A1 gezeigten Lösung weisen die Stufen die übliche, erhebliche Höhe auf. Die Unterseite des Stufenkörpers ist einklappbar, um die Bauhöhe zu verringern. Dies ist ein erheblicher Konstruktionsaufwand.At the in the WO 99/52808 A1 The solution shown has the steps of the usual, considerable height. The underside of the step body can be folded in to reduce the overall height. This is a significant design effort.

Aufgabe der Erfindung ist es, eine Rolltreppe derartiger Art so zu verbessern, dass bei einfacher Konstruktion und hohen Standzeiten eine geringe Bauhöhe in beiden Endbereichen besteht.The object of the invention is to improve an escalator of this type in such a way that, with a simple construction and a long service life, there is a low overall height in both end areas.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst,

  • dass jedes Stufensegment von einer rechtwinkligen Stufenplatte gleichbleibender Höhe gebildet ist, an deren vier Ecken jeweils ein Rad gelagert ist,
  • dass im vorderseitigen Transportbereich der Rolltreppe die vorderen zwei Räder jedes Stufensegments von zwei umlaufenden Transportketten transportiert werden,
  • dass die hinteren zwei Räder jedes Stufensegments auf zwei schrägen ersten Laufbahnen laufen, ohne an Transportketten befestigt zu sein, und
  • dass im rückseitigen Rücktransportbereich die Stufensegmente bei schrägliegender Trittfläche von den zwei umlaufenden Transportketten auf zwei schrägen, hinteren, zweiten Laufbahnen zurück transportiert werden.
According to the invention, this object is achieved in that
  • that each step segment is formed by a rectangular step plate of the same height, with a wheel mounted on each of the four corners,
  • that in the front transport area of the escalator, the two front wheels of each step segment are transported by two circulating transport chains,
  • that the rear two wheels of each step segment run on two inclined first tracks without being attached to transport chains, and
  • that in the rear return transport area, the step segments are transported back by the two circulating transport chains on two inclined, rear, second tracks with an inclined tread surface.

Eine solche Ausführung ergibt nicht nur eine einfache Konstruktion und hohe Standzeiten, sondern führt auch zu einer besonders geringen Bauhöhe der Rolltreppe sowohl im unteren als auch im oberen Endbereich, so dass diese Rolltreppe auch dort eingebaut oder verwendet werden kann wo geringe Bauhöhen zur Verfügung stehen.Such a design not only results in a simple construction and a long service life, but also leads to a particularly low overall height of the escalator both in the lower and in the upper end area, so that this escalator can also be installed or used where low overall heights are available.

Die bisher bekannten Fahrtreppen weisen eine so große Bauhöhe auf, dass erhebliche Einsenkungen in den Boden oder Auf- bzw. Abstiegshilfen erforderlich sind, um überhaupt einen Auftritt auf die Treppe oder den Abgang zu ermöglichen.The previously known escalators are so tall that significant depressions in the floor or ascent and descent aids are required in order to even allow stepping onto the stairs or the exit.

Die untere Wendestation erhält eine so geringe Bauhöhe, dass sie direkt betreten werden kann. Das Treppengerüst wird mit einem Verbund mehrerer Träger und darauf angeordneten Laufbahnen und Sperrvorrichtungen ausgeführt.The lower turning station has such a low overall height that it can be entered directly. The stair scaffolding is designed with a combination of several girders and running tracks and locking devices arranged on them.

Durch die vorgeschlagene Verbesserung ergibt sich die Neuheit der Ortsunabhängigkeit einer durchgängigen Fahrtreppe und eine Verschlankung in ihrem gesamten Erscheinungsbild, insbesondere bei der unteren, extrem flachen Wendestation, im weiteren mit dem Gewinn der Anpassungsfähigkeit an unterschiedliche oder wechselnde Höhen der oberen Wendestation. Diese Neuheit erlaubt außer ihrer stationären die mobile Verwendung auf Flugplätzen, Kaianlagen, Messeplätzen usw. mit dem Vorteil der bequemen Überwindung großer Höhen und zugleich der Absenkbarkeit des Perrons für die Transportfahrt und des Einparkens. Beim Einbau in kleineren Bauten ergibt sich der Vorteil der geringen Eintiefung. In allen Anwendungsbereichen ermöglicht die Rolltreppe die millimetergenaue Anpassung an vorgegebene oder wechselnde Höhen auch während des Stufenumlaufs.The proposed improvement results in the novelty of location independence of a continuous escalator and a streamlining of its overall appearance, especially in the lower, extremely flat turning station, further with the gain in adaptability to different or changing heights of the upper turning station. In addition to its stationary use, this novelty allows mobile use at airports, quays, exhibition grounds, etc. with the advantage of easily overcoming great heights and at the same time the platform can be lowered for transport and parking. When installing in smaller buildings, there is the advantage of the small recess. In all areas of application, the escalator enables adjustment to the millimeter to specified or changing heights, even during the step circulation.

Zu diesen genannten Vorteilen führt auch, dass im unteren und oberen Endbereich die Stufensegmente in waagerechter Stellung im vorderseitigen und im rückseitigen Transportbereich auf waagerechten Laufbahnen waagerecht transportiert werden.The fact that in the lower and upper end area the step segments are transported horizontally in the horizontal position in the front and rear transport area on horizontal tracks also leads to these advantages.

Vorzugsweise wird vorgeschlagen, dass es die zwei Transportketten als Kettenglieder Rollen aufweisen, deren Durchmesser gleich den Durchmessern der Räder der Stufensegmente ist.It is preferably proposed that the two transport chains have rollers as chain links, the diameter of which is equal to the diameter of the wheels of the step segments.

Auch ist von Vorteil, wenn die Achsen der Räder jedes Stufensegments unterhalb der Trittfläche angeordnet sind.It is also advantageous if the axles of the wheels of each step segment are arranged below the tread surface.

Vorzugsweise wird vorgeschlagen, dass die Transportketten und Laufbahnen in seitlichen Wangen der Rolltreppe angeordnet sind.Preferably, it is proposed that the transport chains and tracks are arranged in side cheeks of the escalator.

Ferner ist von Vorteil, wenn im unteren und oberen Endbereich der Rolltreppe die Transportketten durch Kettenräder umgelenkt werden.It is also advantageous if the transport chains are deflected by sprockets in the lower and upper end area of the escalator.

Ferner wird vorgeschlagen, dass im oberen und unteren Endbereich der Rolltreppe die Stufensegmente waagerecht geführt sind und hierbei mit ihren Trittflächen eine waagerechte Einstiegs- und Ausstiegsfläche bilden.It is also proposed that the step segments are guided horizontally in the upper and lower end area of the escalator and that their treads form a horizontal entry and exit area.

Ein sicherer Transport und eine sichere Führung der einzelnen Stufensegmente ist dann gegeben, wenn das rückseitige Ende jedes Stufensegments in einem Winkel abgeschrägt ist, der gleich dem Steigungswinkel der Rolltreppe ist.A safe transport and a safe guidance of the individual step segments is given when the rear end of each step segment is beveled at an angle that is equal to the pitch angle of the escalator.

Die Stabilität der Rolltreppe wird wesentlich verbessert, wenn die zwei seitlichen Wangen der Rolltreppe durch U-förmige Träger miteinander verbunden sind, die zugleich Abschlüsse der Untertritt-Bereiche sind.The stability of the escalator is significantly improved if the two lateral cheeks of the escalator are connected to one another by U-shaped supports, which are also the ends of the understep areas.

Auch ist es von Vorteil, wenn im unteren Endbereich zwei zusätzliche Umlenkräder gelagert sind, durch die die hinteren Räder der Stufensegmente umgelenkt werden, so dass eine sichere Umlenkbewegung der einzelnen Stufensegmente gegeben ist.It is also advantageous if two additional deflection wheels are mounted in the lower end area, by means of which the rear wheels of the step segments are deflected, so that there is a reliable deflection movement of the individual step segments.

Ein Einklemmen von Füßen/Schuhen wird erheblich verhindert, wenn im unteren und/oder obersten Zwischenraum (Untertrittbereich) zwischen den Stufensegmenten Schieber beweglich geführt sind, die den hinteren Bereich des Zwischenraums abdecken, während die Höhe des Zwischenraumes sich verringert.Trapping of feet/shoes is significantly prevented if slides are movably guided in the lower and/or uppermost space (understep area) between the step segments, which cover the rear area of the space while the height of the space decreases.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen in senkrechten Schnitten dargestellt und wird im Folgenden beschrieben, es zeigen die Figuren:

An embodiment of the invention is shown in the drawings in vertical sections and is described below, the figures show:
Figure 1:
The escalator at the bottom and
Figure 2:
the escalator at the top.

Die Rolltreppe weist eine Vielzahl von Stufensegmenten 1 auf, die jeweils von einer rechtwinkligen Stufenplatte gleichbleibend geringer Höhe gebildet sind. Die Oberseite des Stufensegments bildet eine Trittfläche 3 und an jeder der vier Ecken ist ein Rad 2 gelagert, deren Achse jeweils unterhalb der Trittfläche 3 liegt. Die vorderen zwei Räder 2a sind jeweils an einer Transportkette 4 befestigt, die von einer Rollenkette mit Rollen 7 gebildet ist. Die hinteren zwei Räder 2b der Stufensegmente 1 laufen auf ersten schrägen Laufbahnen 5 und sind an keiner Kette befestigt.The escalator has a large number of step segments 1, each of which is formed by a rectangular step plate of consistently low height. The upper side of the step segment forms a step surface 3 and a wheel 2 is mounted at each of the four corners, the axis of which lies below the step surface 3 in each case. The two front wheels 2a are each fastened to a transport chain 4 which is formed by a roller chain with rollers 7 . The rear two wheels 2b of the step segments 1 run on first inclined tracks 5 and are not attached to any chain.

Im vorderseitigen Transportbereich C liegen die Stufensegmente mit ihrer Stufenplatte und Trittfläche 3 waagerecht, während im rückseitigen Transportbereich D die Stufenplatten und Trittflächen 3 schräg geneigt liegen. Hierbei laufen die Stufensegmente 1 in ihrer schrägen Lage mit ihren vier Rädern 2a, 2b auf hinteren zweiten Laufbahnen 6.In the front transport area C, the step segments are horizontal with their step plate and tread 3, while in the rear transport area D the step plates and treads 3 are inclined. In this case, the step segments 1 run in their inclined position with their four wheels 2a, 2b on rear second tracks 6.

Die hinteren Enden 15 der Stufensegmente sind in einem Winkel α abgeschrägt, der dem Steigungswinkel der Rolltreppe entspricht, so dass eine sichere Führung der Stufensegmente an der ersten Laufbahn 5 gegeben ist.The rear ends 15 of the step segments are beveled at an angle α, which corresponds to the incline angle of the escalator, so that the step segments are reliably guided on the first runway 5 .

Sowohl im unteren Endbereich (untere Wendestation) A als auch im oberen Endbereich (obere Wendestation) B laufen die zwei seitlichen Transportketten 4 waagerecht, so dass die Stufensegmente 1 dort waagerecht geführt werden, zumal dort auch die Laufbahnen 5, 6 waagerecht angeordnet sind. Hierbei werden die Transportketten 4 an den äußeren Enden beider Endbereiche A, B durch Kettenräder 9, 10 umgelenkt.Both in the lower end area (lower turning station) A and in the upper end area (upper turning station) B, the two lateral transport chains 4 run horizontally, so that the step segments 1 are guided horizontally there, especially since the tracks 5, 6 are also arranged horizontally there. Here, the transport chains 4 are deflected by chain wheels 9, 10 at the outer ends of both end regions A, B.

Eine solche Konstruktion erlaubt es in den Endbereichen A, B, insbesondere im unteren Endbereich A den Abstand der oberen und unteren Stufensegmente 1 voneinander gering zu halten, so dass die Rolltreppe in den Endbereichen eine niedrige Bauhöhe H aufweisen kann.Such a construction allows the distance between the upper and lower step segments 1 to be kept small in the end areas A, B, particularly in the lower end area A, so that the escalator can have a low overall height H in the end areas.

Zudem befinden sich in beiden Endbereichen A, B noch Umlenkräder 16, die die hinteren Räder 2b aufnehmen, während das jeweilige Stufensegment 1 umgelenkt bzw. umgedreht (gewendet) wird.In addition, there are deflection wheels 16 in both end regions A, B, which accommodate the rear wheels 2b, while the respective step segment 1 is deflected or reversed (turned).

Zu beiden Seiten der Rolltreppe befindet sich jeweils eine Wange 8, die die Transportketten und die Laufbahnen 5, 6 aufnehmen. Die Wangen 8 sind miteinander durch U-förmige Träger (nicht dargestellt) verbunden, die der Stabilität dienen und zudem Abschlüsse der Untertritt-Bereiche 19 sind.There is a cheek 8 on each side of the escalator, which accommodates the transport chains and the tracks 5, 6. The cheeks 8 are connected to one another by U-shaped supports (not shown), which are used for stability and are also ends of the understep areas 19 .

Wenn ein Stufensegment 1 sich einem Endbereich (A oder B) nähert, verringert sich der Abstand des Stufensegments 1 zum benachbarten Stufensegment 1, d. h. der Zwischenraum zwischen beiden Stufensegmenten (auch "Untertrittbereich" 19 bezeichnet) wird kleiner. In diesem Untertrittbereich kann hierdurch der Fuß/Schuh eines Benutzers der Rolltreppen eingeklemmt werden. Um dies zu verhindern befindet sich im Untertrittbereich ein waagerecht beweglicher Schieber, der den Untertrittbereich frei räumt, während der Zwischenraum kleiner wird.As a step segment 1 approaches an end region (A or B), the distance of the step segment 1 to the adjacent step segment 1 decreases, i. H. the space between the two step segments (also referred to as "understep area" 19) becomes smaller. As a result, the foot/shoe of a user of the escalators can be trapped in this understep area. To prevent this, there is a horizontally movable slider in the understep area, which clears the understep area while the space in between becomes smaller.

Die Trittkörper sind auf der Oberfläche und an der vorderen und hinteren Seite gerillt und an den Kanten eckig oder abgerundet. Sie sind mit den Trag- und Zugeinrichtungen des Stufengliederbandes verbunden und korrespondieren mittels der hinteren Abschrägungen mit allen Abschlussvorrichtungen. Sie können Durchbrüche, Teilungen, Einschnitte oder Einschlüsse etc. aufweisen, jedoch keine Überschreitungen ihrer prinzipiell flachen, quaderartigen Kontur.The tread bodies are grooved on the surface and on the front and rear sides and are square or rounded on the edges. They are connected to the carrying and pulling devices of the step link belt and correspond to all end devices by means of the rear bevels. They can have openings, divisions, incisions or inclusions, etc., but not exceeding their basically flat, cuboid contour.

Die Wendestationen sind mit den Lagern für das Treppengerüst, mit der Antriebsvorrichtung für das Stufengliederband und mit den im Schacht angeordneten beweglichen oder unbeweglichen Absperrvorrichtungen für den Personen- und Havarieschutz ausgestattet; ferner mit Vorrichtungen für die Kettenspannung, für die Umlenkung des Stufengliederbandes, für die nach innen abgeknickten Rollenbahnen und für die Überleitungen des Stufengliederbandes an den Verbindungsstellen der Baugruppen. Sie können mit einem zusätzlichen Antrieb mit einer zusätzlichen Antriebswelle ausgestattet sein.The turning stations are equipped with the bearings for the stair scaffolding, with the drive device for the step belt and with the movable or immovable barrier devices for personal and accident protection arranged in the shaft; also with devices for the chain tension, for the deflection of the step link belt, for the inwardly bent roller conveyors and for the transitions of the step link belt at the connection points of the assemblies. They can be equipped with an additional drive with an additional drive shaft.

Die Abdeckung der Wendestation wird mit einer Herabkröpfung im Schachtbereich ausgeführt. Bürstenbänder, Noppen- und Sattelläufe dichten die Schlitze der Bahnen bzw. der Mitnehmerbolzen des Stufengliederbandes und der hinteren Stufenrolle ab. Der Handlauf ist unterhalb des Griffbereichs mit einem Noppenschutz ausgestattet und kann mit einer Desinfektionseinrichtung versehen sein.The cover of the turning station is designed with an offset in the shaft area. Brush belts, nubbed and saddle runs seal the slots of the tracks or the driver bolts of the step link belt and the rear step roller. The handrail is equipped with a nub protection below the grip area and can be equipped with a disinfection device.

Der Korpus kann Vorrichtungen zur Reinigung, zur Erzielung des atmosphärischen Überdrucks, der Kühlung, der Beheizung und anderer Schutz- und Sicherheitsvorrichtungen aufweisen.The body may have devices for cleaning, for obtaining the atmospheric overpressure, cooling, heating and other protective and safety devices.
