Definitions
- the present invention relates to an escalator or moving walk with circumferential handrail having a fixed guide device and a handle body moving in operation along the guide device.
- handrails are known to have a C-shaped cross-section and are usually constructed from a variety of different materials.
- the dimensional stability of the C-shaped handrail must be ensured throughout its lifetime, since for safety reasons, the gaps between the moving handrail and a fixed balustrade must be minimal.
- a lifting of the handrail by the passenger is to be prevented.
- the sliding layer is the contact surface of the handrail for both the handrail guide and the handrail drive system. Therefore, the sliding layer must have a good low friction sliding performance. But since it is driven on the same surface, it must on the other hand have a very good stiction because otherwise the handrail can not be driven.
- the handrail has a sturdy, fixed guide rail.
- the guide rail surrounds a handle body which moves during operation of the moving walk along the guide rail.
- the guide rail - and thus also the handle body - has a different cross-sectional shape than in the area accessible to persons.
- document FR-A-2 757 143 discloses a handrail according to the preamble of claim 1.
- a guide device is provided with a shaping guide profile, which includes a lip guide, which extends along a longitudinal direction of the guide profile. Furthermore, the grip body has two end lips. The end lips are formed so that they run parallel to the longitudinal direction with moving handle body in the lip guide.
- the shape of the guide profile dictates the shape of the handrail in the direction parallel to the longitudinal direction and in cross section.
- the handrail is variable in its cross-sectional shape.
- the handrail may have sections of different shapes.
- the novel handrail provides improved safety for passenger transport through a user-friendly and ergonomic handrail shape.
- a lower forming work by the special design of the handrail and a lower drive power is required.
- the abrasion of the handrail is reduced by the lower volume or weight and by the separation of the contact surface in a handrail guide surface and handrail drive surface together with an optimization of the individual surfaces.
- the use of the novel handrail also makes it possible to achieve an elegant appearance for escalators and moving walks.
- moving walk is used as a synonym for bridge-type means of transport (moving walks) or stair-like means of transport (Escalators), as used in passenger or object transport.
- moving walkway is also used as a synonym for other passenger or object transport systems, such as those used at airports to bridge larger distances.

Abstract
Description
Die vorliegende Erfindung betrifft eine Fahrtreppe oder einen Fahrsteig mit umlaufendem Handlauf, der eine feste Führungsvorrichtung und ein im Betrieb sich entlang der Führungsvorrichtung bewegenden Griffkörper aufweist.The present invention relates to an escalator or moving walk with circumferential handrail having a fixed guide device and a handle body moving in operation along the guide device.
Es gibt zahlreiche Ausführungs- und Gestaltungsformen für den Handlauf einer Fahrtreppe oder eines Fahrsteigs.There are numerous designs and designs for the handrail of an escalator or moving walk.
Um den Fahrgast einen sicheren Griff zu ermöglichen, haben Handläufe bekanntlich einen C-förmigen Querschnitt und sind üblicherweise aus einer Vielzahl von unterschiedlichen Materialien aufgebaut. Die Formstabilität des C-förmigen Handlaufs muss während der gesamten Lebensdauer gewährleistet sein, da aus Sicherheitsgründen die Spalte zwischen dem bewegten Handlauf und einer feststehenden Balustrade minimal sein müssen. Ausserdem ist auch ein Abheben des Handlaufs durch den Fahrgast zu verhindern.To allow the passenger a secure grip, handrails are known to have a C-shaped cross-section and are usually constructed from a variety of different materials. The dimensional stability of the C-shaped handrail must be ensured throughout its lifetime, since for safety reasons, the gaps between the moving handrail and a fixed balustrade must be minimal. In addition, a lifting of the handrail by the passenger is to be prevented.
Resultierend aus der geforderten Formstabilität und den Sicherheitsanforderungen haben derzeitige Handläufe ein großes Volumen und eine hohe Lippensteifigkeit, d.h. eine hohe Steifigkeit der Seitenbereiche des Handlaufes. Wegen dieser Formstabilität, und speziell wegen der Lippensteifigkeit, benötigt man eine grosse Umformarbeit des Handlaufs. Die Formstabilität und Lippensteifigkeit erschwert das Biegen des Handlaufs in Längsrichtung speziell in Umlenkbögen, Übergangsbögen und beim Handlaufantriebsrad. Durch das größere Volumen und dadurch größere Gewicht des Handlauf benötigt man eine grosse Antriebsleistung, um den Handlauf zu bewegen.As a result of the required dimensional stability and safety requirements, current handrails have a large volume and a high lip stiffness, ie a high rigidity of the side regions of the handrail. Because of this dimensional stability, and especially because of the lip stiffness, one needs a large forming work of the handrail. The dimensional stability and lip stiffness makes it difficult to bend the handrail in the longitudinal direction, especially in deflection bends, transition bends and in the handrail drive wheel. Due to the larger volume and thus greater weight of the handrail requires a large drive power to move the handrail.
Ebenfalls muss eine sogenannte Gleitlage, die auf der Innenseite des Handlaufs vorgesehen ist, gleich zwei Funktionen erfüllen. Die Gleitlage ist die Kontaktfläche des Handlaufs sowohl für die Handlaufführung als auch für das Handlaufantriebssystem. Daher muss die Gleitlage eine gute Gleitfähigkeit mit geringer Haftreibung haben. Da aber auf der selben Fläche auch angetrieben wird, muss sie andererseits eine sehr gute Haftreibung aufweisen da sonst der Handlauf nicht angetrieben werden kann.Also has a so-called sliding layer, which is provided on the inside of the handrail to fulfill two functions. The sliding layer is the contact surface of the handrail for both the handrail guide and the handrail drive system. Therefore, the sliding layer must have a good low friction sliding performance. But since it is driven on the same surface, it must on the other hand have a very good stiction because otherwise the handrail can not be driven.
Aus der Japanischen Patentpublikation
Nachteilig an dieser Konstellation ist einerseits die relativ grosse Berührungsfläche zwischen der Innenseite des Griffkörpers und der Führungsschiene, was zu Reibung und Verschleiss führt. Aus Sicherheitsgründen besonders kritisch ist aber die Grösse der Spalte zwischen dem sich bewegenden Griffkörper und der feststehenden Führungsschiene.A disadvantage of this constellation, on the one hand, the relatively large contact area between the inside of the handle body and the guide rail, which leads to friction and wear. For safety reasons, however, the size of the gap between the moving handle body and the fixed guide rail is particularly critical.

Es ist Aufgabe der vorliegenden Erfindung, eine Fahrtreppe bzw. einen Fahrsteig der eingangs genannten Art bereit zu stellen, die/der eine Verbesserung der Sicherheit für den Fahrgast im Vergleich zu derzeitigen Lösungen ermöglicht.It is an object of the present invention to provide an escalator or a moving walk of the type mentioned, which / allows an improvement in safety for the passenger compared to current solutions.
Ausserdem ist es eine Aufgabe der vorliegenden Erfindung, eine Fahrtreppe bzw. einen Fahrsteig der eingangs genannten Art bereit zu stellen, die/der geringere Reibung und reduzierten Verschleiss aufweisen. Ausserdem ist die Antriebseffizienz zu verbessern.Moreover, it is an object of the present invention to provide an escalator or a moving walk of the type mentioned, the / have lower friction and reduced wear. In addition, the drive efficiency is to be improved.
Diese Aufgabe wird bei einem Fahrsteig bzw. einer Fahrtreppe der eingangs genannten Art erfindungsgemäss dadurch gelöst, dass eine Führungsvorrichtung mit einem formgebenden Führungsprofil vorgesehen ist, das eine Lippenführung umfasst, die sich entlang einer Längsrichtung des Führungsprofils erstreckt. Weiterhin weist der Griffkörper zwei Endlippen auf. Die Endlippen sind so ausgebildet, dass sie bei sich bewegendem Griffkörper in der Lippenführung parallel zu der Längsrichtung laufen. Das Führungsprofil gibt durch seine Formgebung die Form des Handlaufs in Richtung parallel zur Längsrichtung und im Querschnitt vor.This object is achieved in a moving walk or an escalator of the type mentioned in the present invention that a guide device is provided with a shaping guide profile, which includes a lip guide, which extends along a longitudinal direction of the guide profile. Furthermore, the grip body has two end lips. The end lips are formed so that they run parallel to the longitudinal direction with moving handle body in the lip guide. The shape of the guide profile dictates the shape of the handrail in the direction parallel to the longitudinal direction and in cross section.
Es wird als ein Vorteil der Erfindung angesehen, dass der Handlauf in seiner Querschnittformgebung variabel ist. Somit kann in besonders vorteilhaften Ausführungsformen der Handlauf Abschnitte mit unterschiedlichen Formen aufweisen.It is considered as an advantage of the invention that the handrail is variable in its cross-sectional shape. Thus, in particularly advantageous embodiments, the handrail may have sections of different shapes.
Es wird auch als besonders vorteilhaft angesehen, dass der neuartige Handlauf eine verbesserte Sicherheit für den Personentransport durch eine benutzerfreundliche und ergonomische Handlaufform bietet. Ausserdem ist eine geringere Umformarbeit durch die spezielle Ausführung des Handlaufs und eine geringere Antriebsleistung erforderlich. Auch ist der Abrieb des Handlaufs durch das geringere Volumen bzw. Gewicht und durch die Trennung der Kontaktfläche in eine Handlaufführungsfläche und Handlaufantriebsfläche zusammen mit einer Optimierung der einzelnen Oberflächen geringer.It is also considered to be particularly advantageous that the novel handrail provides improved safety for passenger transport through a user-friendly and ergonomic handrail shape. In addition, a lower forming work by the special design of the handrail and a lower drive power is required. Also, the abrasion of the handrail is reduced by the lower volume or weight and by the separation of the contact surface in a handrail guide surface and handrail drive surface together with an optimization of the individual surfaces.
Durch die Verwendung des neuartigen Handlaufs kann ausserdem für Fahrtreppen und Fahrsteige neben den rein funktionalen und sicherheitstechnischen Aspekten auch ein elegantes Aussehen erreicht werden.In addition to the purely functional and safety-related aspects, the use of the novel handrail also makes it possible to achieve an elegant appearance for escalators and moving walks.

Vorzugsweise befindet sich auf der Rückseite im Bereich des Antriebsrades 13 ein Gegenauflager, wobei der Grundkörper 4 zwischen dem Gegenauflager und dem Antriebsrad 13 hindurch gezogen wird.The front side of the
Durch diese spezielle Ausführungsform des Antriebsprofils 12 können beim Antriebsystem größere Kontaktflächen bereit gestellt werden als bei herkömmlichen Handläufen, da das Führungsprofil 3 so gestaltet ist, dass der Grundkörper 4 des Griffstücks 2 ganz flach gegen das Antriebrad 13, respektive das Antriebrad 13 gegen den Grundkörper 4, gepresst wird.By this particular embodiment of the
In allen gezeigten Ausführungsformen ist die Länge des Kurvenzugs (in
Damit die vorgeschriebene Sicherheit für den Fahrgast sichergestellt werden kann, können die Führungsprofile 3 so gestaltet werden, dass der Fahrgast einen sicheren Griff an dem Griffstück 2 hat. Der bekannte C-förmige Querschnitt kann mit einem entsprechend geformten Führungsprofil 3 erreicht werden.
Besonders bevorzugt ist ein Handlauf, der entlang seiner Längsachse L den Querschnitt ändert. Diese Art der Ausführungsform wird als Handlauf mit variablem Querschnitt bezeichnet. Dies wird anhand eines Beispiels beschrieben. Vom Anfang bis ca. 1 m vor dem Ende eines Fahrsteigs, zum Beispiel, kann der Handlauf die in
Darüber hinaus kann die Sicherheit für den Fahrgast noch verbessert werden wenn kurz vor dem Ausstieg aus der Fahrtreppe bzw. Fahrsteig das Führungsprofil 3 in ein Ausstiegsprofil übergeht. Das Ausstiegsprofil kann zum Beispiel ein Flachprofil (
Eine weitere Verbesserung der derzeitigen Sicherheit für den Fahrgast kann durch ein dem Fahrgast zugeneigtes Griffstück 2 erreicht werden. In diesem Fall wird während der Fahrt auf der Fahrtreppe bzw. Fahrsteig die Geometrie des Führungsprofil 3 derart gestaltet, dass das Griffstück 2 zu dem Fahrgast hin geneigt. Das in den
Damit, wie beschrieben, bei den Umlenkbögen und dem Handlaufantriebsrad der erfindungsgemässe Handlauf weniger Umformarbeit zu leisten hat, können die Führungsprofile 3 so gestaltet werden, dass der Grundkörper 4 des Griffstücks 2 flach ist (siehe
Weiterhin können im Bereich des Antriebsystems größere Kontaktflächen bereitgestellt werden wenn das Führungsprofil 3 so gestaltet wird, dass der Grundkörper 4 des Griffstücks 2 ganz flach (siehe
Durch die geringere Umformarbeit in den Umlenkbögen, die verbesserten Gleiteigenschaften (reduzierte Reibung), die durch den Einsatz dedizierter Gleitflächen 6 oder Gleitbereiche des Grundkörpers 4 und gegebenenfalls Profilgleitflächen 9 des Führungsprofils 3 erzielt wird, und die größere Kontaktfläche zum Antrieben des Griffstück 2 und durch das geringere Volumen bzw. Gewicht der bewegten Teile des Handlaufs wird weniger Antriebsleistung für den erfindungsgemässen Handlauf benötigt. Ausserdem treten weniger Schleifgeräusche auf und der Handlauf erwärmt sich nicht so stark wie das teilweise beim Stand der Technik vorkommen kann.Due to the lower forming work in the Umlenkbögen, the improved sliding properties (reduced friction), which is achieved by the use of dedicated sliding
Handläufe nach dem Stand der Technik haben teilweise eine sogenannte Gleitlage auf der Innenseite des Handlaufs, die Kontaktfläche des Handlauf sowohl für die Handlaufführung als auch dem Handlaufantriebssystem ist. Gemäss Erfindung werden die Gleitfunktion und die Antriebsfunktion voneinander getrennt, wie im Zusammenhang mit den
- 1. Gemäss Erfindung ergeben sich zahlreiche weitere Vorteile, die je nach Ausführungsform, Materialwahl und Dimensionierung mehr oder wenig stark ausgeprägt sein können. Laut Erfindung wird nicht mehr ein in sich formstabiler C-förmiger Querschnitt verwendet, der typischerweise aus mehreren Schichten aufgebaut ist. Weiterhin kann der Querschnitt des erfindungsgemässen Handlaufs, respektive des
Grundkörpers 4, extrem dünn ausgebildet sein.Der Grundkörper 4 kann aus einem einzelnen Material, z.B. einer Elastomermischung oder einem Gewebe aufgebaut sein. Um der geforderten Sicherheit für den Personentransport gerecht zu werden, wird der dünne und leicht verformbare Querschnitt des erfindungsgemässen Handlaufs durch spezielle Führungsprofile 3 benutzerfreundlich und ergonomisch geformt wobei die Möglichkeit besteht die Geometrie des Handlaufs entlang der Fahrtreppe speziell den Bedürfnissen der Fahrgäste anzupassen, wie erwähnt. Der Griffkörper (2) kann aus Metallgewebe, Kunststoffgewebe, Naturfaser, Füllstoffe in Hülle aufgebaut sein. Füllstoffe sind z.B. Gel, Flüssigkeit, Schaumstoffe. Die Hülle ist ein Schlauch oder PVC-Ummantellung.
- 1. According to the invention, there are numerous other advantages that can be more or less pronounced depending on the embodiment, choice of material and dimensions. According to the invention is no longer used in a dimensionally stable C-shaped cross-section, which is typically constructed of several layers. Furthermore, the cross section of the handrail according to the invention, respectively of the
base body 4, can be made extremely thin. Thebase body 4 may be constructed of a single material, for example an elastomeric mixture or a fabric. In order to meet the required safety for passenger transport, the thin and easily deformable cross section of the inventive handrail is made user-friendly and ergonomic byspecial guide profiles 3 with the possibility of adjusting the geometry of the handrail along the escalator especially the needs of passengers, as mentioned. The handle body (2) may be constructed of metal fabric, plastic fabric, natural fiber, fillers in shell. Fillers are eg gel, liquid, foams. The shell is a tube or PVC Ummantellung.
Gemäss Erfindung gibt es nur noch eine geringe Zahl von Zugträgern 7, z.B. ein Stahlseil, um die Längskräfte aufzunehmen. Weiterhin kann man mit der Erfindung eine Trennung der Kontaktfläche in eine Handlaufführungsfläche, vorzugsweise mit Gleitflächen 6 versehen, und eine Handlaufantriebsfläche vornehmen, wobei diese Flächen jeweils für die jeweilige Anwendung optimiert werden können.According to the invention, there are only a small number of
In einer speziellen Ausführungsform ist der Grundkörper mindestens teilweise durchsichtig ausgeführt. Damit kann man einen Beleuchtungs- aber auch einen Sicherheitseffekt erzielen. So kann durch Beleuchtungsänderung am Anfang und/oder Ende eines Handlaufs die Aufmerksamkeit erhöhen.In a special embodiment, the base body is at least partially transparent. This can be a lighting but also achieve a security effect. Thus, by changing the lighting at the beginning and / or end of a handrail can increase the attention.
Auch können durch die flexible Geometrie des erfindungsgemässen Handlaufs gezielt die Gleitflächen und Antriebsflächen getrennt werden. Dadurch kann, bei geeigneter Optimierung eine verbesserte Antriebsperformance und Gleitperformance erzielt werden kann. Dadurch ergibt sich eine längere Lebensdauer des Handlauf. Auch kann durch die verbesserten Gleitflächen unter Umständen auf Kugellager in den Umlenkbögen verzichtet werden.Also, the sliding surfaces and drive surfaces can be selectively separated by the flexible geometry of the inventive handrail. As a result, with suitable optimization, improved drive performance and sliding performance can be achieved. This results in a longer life of the handrail. Also can be dispensed with ball bearings in the Umlenkbögen under certain circumstances by the improved sliding surfaces.
Die Formstabilität des erfindungsgemässen Handlaufs wird durch das Zusammenwirken erreicht. D.h., die strukturelle Stabilität wird erst erzielt wenn der Grundkörper 4 um das Führungsprofil 3 herum angeordnet ist.The dimensional stability of the inventive handrail is achieved by the interaction. That is, the structural stability is achieved only when the
Anders als beim Stand der Technik ist der Grundkörper 4 nicht in sich formhaltig. Der Grundkörper 4 hat eine sehr geringe horizontale (laterale) und vertikale (normale) Stabilität. Ausserdem hat der Grundkörper 4 nur eine sehr geringe Torsionssteifigkeit. Die Zugstabilität muss aber ausreichend hoch sein. D.h. es muss eine Mindestzugfestigkeit gewährleistet sein.Unlike the prior art, the
Die Anwendung dieser Erfindung wurde anhand verschiedener Ausführungsformen beschrieben. Die Erfindung lässt sich, wie eingangs betont, nicht nur auf Fahrsteige sondern auch auf Fahrtreppen anwenden.The application of this invention has been described in terms of various embodiments. The invention can be, as At the beginning stresses not only on moving walks but also on escalators.
Durch den relativ flexiblen Aufbau des erfindungsgemässen Handlaufs kann man auch problemlos schraubenförmig oder bogenförmig angelegte Fahrsteige realisieren. Mit dem erfindungsgemässen Handlauf kann man problemlos auch kleinere Krümmungsradien im Raum überwinden, ohne einen übermässigen Widerstand zu verursachen oder Verschleiss und damit einhergehenden Schleifgeräusche hervor zu rufen.Due to the relatively flexible structure of the inventive handrail you can also easily realize helical or arcuate moving walkways. With the inventive handrail you can easily overcome even minor radii of curvature in space, without causing excessive resistance or wear and concomitant grinding noises to call out.
Der Handlauf kann auch besonders vorteilhaft als Werbeträger eingesetzt werden.The handrail can also be used particularly advantageously as an advertising medium.
Erfindungsgemässe Fahrsteige bzw. Fahrtreppen können bei Messen, Ausstellungen, Bahnhöfen und so weiter Anwendung finden.Moving stairs or escalators according to the invention can be used at trade fairs, exhibitions, railway stations and so on.
