Definitions
- the invention relates to an escalator with steps, a step of such an escalator and a method to modernize an escalator, according to the definition of the independent claims.
- the steps of a conventional escalator are attached to two transport chains and together with these form an endless, revolving step band, which runs over a pair of transport sprockets at both ends of the escalator, one transport sprocket pair belonging to the drive station and driving and deflecting the step belt and the other Sprocket pair is part of a step-band diverter station.
- the individual steps of the step belt are equipped with two front and two rear guide rollers on which the steps are guided by guiding and deflection curves, which are fastened predominantly to the supporting structure of the escalator, in position-dependent defined position.
- the steps of an escalator run along a predetermined path, which is laterally defined by the fixed base plate.
- Such a gap or air gap is a security risk. Due to the two-sided game, the gap width can reach a larger area, so that a Schuhkanten-, Schal-, Stöckel-, Rocksaum- or manual intervention, especially in children, is possible. As a result, the risk of bruising and other injuries to the passenger is not excluded.
- the patent WO98 / 24714 discloses, for example, base plate brushes which are mounted as deflectors on the base plate but above the steps. These base plate brushes direct rectilinear objects z. As a leg, away from the gap between the base plate and step. However, a foot of the leg can be rotated so that the toes are in the direction of the column and the brushes do not prevent penetration into the gap.
- the patent US5695040 discloses slots which are mounted laterally of the step and in which brushes are arranged.
- This solution has the disadvantage that the blocking brushes are located at a certain distance below the tread surface or riser surface, so that objects can pinch into the overlying gap.
- the brushes are in contact with the base plate, damage the base plate and cause noise.
- the brushes have a very short life due to the constant friction with the base plate. The forces exerted by the steps damage the structure of the brushes, which then have insufficient dimensional stability.
- JP 2003 073 065 discloses an escalator with step brushes.
- the invention is therefore an object of the invention to provide an escalator, which does not have the disadvantages mentioned above and the reliability significantly increases ease of manufacture and significantly extends the life.
- step brushes are arranged on the tread edge.
- the step surface is the area of the escalator step on which the passengers are standing.
- the tread edge includes the geometric line delimiting the tread surface and the immediate vicinity of this geometric line on the tread surface.
- stage brushes positioned as described above provide a necessary contact prevention of objects with the base plate.
- the step brushes prevent the contact of objects with the base plates and at the same time the penetration of the objects into the gap between the base plate and the passing stage or step band. Furthermore, by using the step brushes two unwanted friction partners are brushed apart. Foreign objects, such as: shoes, umbrellas, bags, plastic bags or other objects are brushed away from the base plate using the step brushes, the step brushes push the objects from the danger area, ie base plate and step gap, or brush. Consequently, chewing or wedging objects is not possible or very much prevented. The use of the escalator is thereby significantly improved and security increased essential.
- the brushes release any frictional contact before they can penetrate into the gap between the moving steps and the fixed base plate. Especially when the transition radii where not only a relative movement between the steps and the base plate is present, but also a relative movement between two adjacent stages takes place, namely, when a horizontal tread approaching in front of her riser in upward motion, by the brushes each Frictional contact in this critical area between tread and riser prevented.
- the step brushes are arranged along the entire tread edge in the normal direction to the tread surface.
- the brushes according to the invention are thus mounted or arranged in such a way that the brushes are normal to the tread surface and project beyond the base plate and thus do not touch the base plate.
- a contact with the base plate takes place only when an object comes into frictional contact with the base plate.
- any frictional contact between two objects is prevented from penetrating into the gap, between the movable step and the fixed base plate.
- the steps have a riser surface with at least one riser edge on which step brushes are arranged.
- the riser surface is the front approximately vertical surface of the escalator step. Often it is curved or rounded or convex.
- the riser edge is the geometric line delimiting the riser surface and the immediate vicinity of this geometric line on the riser surface.
- An advantage of this embodiment is that the risk of the penetration of an object into the air gap is further reduced.
- the step brushes are arranged along the entire setting step edge in the normal direction to the riser surface.
- the directed away from the base plate brushes do not touch the base plate, which is why there is no friction and the base plate and the brushes have a long life.
- the step brushes made of plastic bristles or brass bristles or galvanized steel bristles.
- the step brushes are sprayed or glued or screwed or glued or snapped fixed on the steps. Cost-effective and simple conventional production methods of the brushes can thus be used.
- the tread edge is a separate mechanical plastic component of the step and the step brushes are molded or injected or glued attached to the tread edge.
- the step brushes can thus be made separately with the plastic component that forms the tread edge. The entire component is then later mounted on the step body in a quick and easy manner.
- Such a separate tread edge is easily removable and replaceable.
- stepping brushes are on one step for an escalator all the way around Tread edge with normal direction to the tread surface arranged.
- Such a stage can be easily and inexpensively produced as a semi-finished product and then quickly and easily be used on an escalator.
- an escalator with steps having a tread surface with a tread edge is modernized, in which tread brushes are attached to the tread edge.
- a step 1 for an escalator which has a tread surface 4 with at least one tread edge 2, wherein step brushes 3 are arranged on the tread edge 2.
- the step brushes 3 are arranged along the entire tread edge 2 in the normal direction to the tread surface 4.
- the stage 1 also has a riser surface 5 with a riser edge 6, are also arranged on the step brush 3.
- the step brushes 3 are arranged along the entire setting step edge 6 in the normal direction to the riser surface 5.
- step brushes 3 are mounted on all escalator steps. Stepped brushes 3 are located on the step as well as on the riser. Stepped brushes 3 are placed on escalator step 1 on the left and right.
- the step brushes 3 prevent by pinching a pinching or grinding of shoes, umbrellas, bags, plastic bags or other objects. They prevent any foreign elements from entering: newspaper pieces, plastic bags, pebbles, garment fibers and coarse dirt, as well as snow and ice.
- step brushes 3 lies in the fan-like and therefore shut-off lineup.
- the step gap is barricaded and it is impossible to reach the escalator side edge.
- the step brushes 3 prevent like a dense wall of plastic bristles the penetration or reaching the base plate step gap.
- a dense, hermetic, impermeable bristle boundary is now located on the left and right of escalator stage 1.
- the step brushes 3 can be sprayed or glued or screwed or glued or snapped fixed on the escalator level 1.
- Fig. 2 shows a schematic arrangement of an escalator step 1 with the novel step brushes 3 and with a separate plastic step edge 2.
- the tread edge 2 is according to this particular embodiment of the invention, a separate mechanical plastic component of stage 1 and the step brushes 3 are molded or injected or glued on the Stepped edge 2 attached.
- Such plastic edges are preferably yellow to give a clear visual indication to the passengers that there is a gap. A clear visibility of danger or respect is thus given.
- the step brushes 3 are thus produced together with the yellow plastic edges 2 and mounted together on the step body 1 or screwed.
- the step brushes 3 form a barrier or barrier to the passengers and inhibit or make it difficult to touch the base plate. It can not be made a connection to the base plate gap and a chewing or wedging or pinching is impossible.
- the step brushes 3 thus decouple the fixed (base plate) from the moving (escalator step) components.
- step brushes 3 are designed so compact that they withstand the burden of passenger traffic. Therefore, a durable, resistant, insensitive brush material should be used, such as plastic bristles or brass bristles or galvanized steel wire bristles. The sufficient dimensioning and design of the step brushes 3 is given due to the number of passengers and their resulting stresses.
- the bristles of the brushes are corrugated. This is advantageous because such bristles have a higher dimensional stability and longer life.
- the end of the bristles of the step brushes is rounded. This is advantageous because the risk of injury to the passengers upon contact with the bristles is reduced.
- Fig. 3 shows step brushes 3 with straight bristles while Fig. 4 Stepped brushes 3 with wavy bristles shows.
- the wave structure increases the mechanical strength of the bosts and allows a better distribution of the forces exerted by objects or passengers.
- the wave structure stabilizes the bristles against bending obliquely to the longitudinal axis compared to the straight bristles. When the straight bristles are pressed in the longitudinal axis, they bend and can no longer exert any counterforce. In contrast, the wavy bristles absorb the pressure in the longitudinal axis as spring tension stored in the shafts, the bristles maintain their alignment and are not bent.
- the corrugated bristles significantly reduce the gap between the running, powered escalator step 1 and the pedestal panel, thereby further reducing the risk of a foot of a passenger entering the gap or air gap.
- step brushes 3 can be easily installed in a factory along the whole tread edge 2 with normal orientation to the tread surface.
- This solution allows a quick and easy mounting of the step brushes 3 on the escalator and reduces the manufacturing costs and installation costs.
- This modernization method allows by attaching the step brushes 3 a quick and easy improvement of the escalator, in terms of operational safety and passenger safety, since the risk of entrapment or Einzwickgefahr or risk of jamming is prevented.
Description
Die Erfindung betrifft eine Fahrtreppe mit Stufen, eine Stufe einer solchen Fahrtreppe sowie ein Verfahren um eine Fahrtreppe zu modernisieren, gemäss der Definition der unabhängigen Patentansprüche.The invention relates to an escalator with steps, a step of such an escalator and a method to modernize an escalator, according to the definition of the independent claims.
Die Stufen einer üblichen Fahrtreppe sind an zwei Transportketten befestigt und bilden zusammen mit diesen ein endloses, umlaufendes Stufenband, das über je ein Paar Transportkettenräder an beiden Enden der Fahrtreppe läuft, wobei das eine Transportkettenradpaar zur Antriebsstation gehört und das Stufenband antreibt und umlenkt und das andere Kettenradpaar Teil einer Stufenband-Umlenkstation ist. Die einzelnen Stufen des Stufenbands sind mit je zwei vorderen und zwei hinteren Führungsrollen ausgerüstet, an denen die Stufen durch vorwiegend an der Tragkonstruktion der Fahrtreppe befestigte Führungs- und Umlenkkurven in positionsabhängig definierter Lage geführt werden.The steps of a conventional escalator are attached to two transport chains and together with these form an endless, revolving step band, which runs over a pair of transport sprockets at both ends of the escalator, one transport sprocket pair belonging to the drive station and driving and deflecting the step belt and the other Sprocket pair is part of a step-band diverter station. The individual steps of the step belt are equipped with two front and two rear guide rollers on which the steps are guided by guiding and deflection curves, which are fastened predominantly to the supporting structure of the escalator, in position-dependent defined position.
Die Stufen einer Fahrtreppe verlaufen entlang einer vorbestimmten Bahn, welche durch das feststehende Sockelblech seitlich definiert wird.The steps of an escalator run along a predetermined path, which is laterally defined by the fixed base plate.
Zum Ausgleich von Toleranzen muss zwischen Sockelblech und Stufe ein Spalt verbleiben, nachdem eine dort anliegende Stufe eine erhebliche Reibung erzeugen würde, die zu einer unzulässigen Erwärmung führen und Antriebsleistung sowie Verschleiss erhöhen würde.To compensate for tolerances must remain a gap between base plate and stage, after a level applied there would generate considerable friction, which would lead to improper heating and drive power and wear would increase.
Aus diesem Grund muss zwischen Sockelblech und Stufe ein Spalt bzw. Luftspalt verbleiben.For this reason, a gap or air gap must remain between base plate and step.
Ein derartiger Spalt bzw. Luftspalt ist ein Sicherheitsrisiko. Aufgrund des beidseitig vorhandenen Spiels kann die Spaltbreite einen grösseren Bereich erreichen, so dass ein Schuhkanten-, Schal-, Stöckel-, Rocksaum- oder Handeingriff, gerade bei Kindern, möglich wird. Infolgedessen ist die Gefahr von Quetschungen und sonstigen Verletzungen für den Fahrgast nicht ausgeschlossen.Such a gap or air gap is a security risk. Due to the two-sided game, the gap width can reach a larger area, so that a Schuhkanten-, Schal-, Stöckel-, Rocksaum- or manual intervention, especially in children, is possible. As a result, the risk of bruising and other injuries to the passenger is not excluded.
Die Verletzung von Personen im Spalt zwischen dem Sockelblech und dem Trittstufenbereich sowie Setzstufenbereich verursacht durch die Relativbewegung zwischen den bewegten Stufen und dem festen Sockelblech ist ein Hauptproblem der herkömmlichen Fahrtreppen. Darüber hinaus, wenn ein auf der bewegten Stufe befindlicher Gegenstand mit dem stehenden Sockelblech in Kontakt kommt, kann der Gegenstand durch Reibung in die Spalte gezogen werden, vor allem bei der Fahrt nach oben.The injury of persons in the gap between the base plate and the tread area and riser area caused by the relative movement between the moving steps and the fixed base plate is a major problem of conventional escalators. In addition, when a moving-stage object comes in contact with the standing pedestal sheet, the article may be dragged into the gap by friction, especially when traveling upwards.
Dementsprechend sind Versuche unternommen worden, eine Abweisfläche zu erzeugen, die einen Eingriff in den Spalt verhindern soll. Aus den Unterlagen gehen verschiedene Abweiser für den Stufenspalt beim Sockelblech hervor.Accordingly, attempts have been made to create a deflection surface intended to prevent engagement in the gap. From the documents go out various deflectors for the step gap at the base plate.
Das Patent
Das Patent
Daher liegt der Erfindung die Aufgabe zugrunde, eine Fahrtreppe zu schaffen, welche die oben genannten Nachteile nicht aufweist und die Betriebssicherheit bei einfacher Herstellbarkeit essentiell steigert und die Lebensdauer deutlich verlängert.The invention is therefore an object of the invention to provide an escalator, which does not have the disadvantages mentioned above and the reliability significantly increases ease of manufacture and significantly extends the life.
Diese Aufgabe wird erfindungsgemäß durch die unabhängigen Ansprüche gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.This object is achieved by the independent claims. Advantageous developments emerge from the subclaims.
Erfindungsgemäss ist es vorgesehen, dass in einer Fahrtreppe mit Stufen, welche eine Trittstufenfläche mit mindestens einer Trittstufenkante aufweisen, Stufenbürsten an der Trittstufenkante angeordnet sind.According to the invention it is provided that in an escalator with steps, which have a tread surface with at least one tread edge, step brushes are arranged on the tread edge.
Als Trittstufenfläche wird die Fläche der Fahrtreppenstufe bezeichnet, auf welcher die Passagiere stehen. Die Trittstufenkante umfasst die geometrische Linie, die die Trittstufenfläche abgrenzt sowie die unmittelbare Umgebung dieser geometrischen Linie auf der Trittstufenfläche.The step surface is the area of the escalator step on which the passengers are standing. The tread edge includes the geometric line delimiting the tread surface and the immediate vicinity of this geometric line on the tread surface.
Derart, wie oben beschriebene, positionierte Stufenbürsten stellen eine erforderliche Kontaktverhinderung von Gegenständen mit dem Sockelblech dar. Die Stufenbürsten verhindern den Kontakt von Gegenständen mit den Sockelblechen und gleichzeitig das Eindringen der Gegenstände in den Spalt zwischen dem Sockelblech und der vorbeifahrenden Stufe bzw. dem Stufenband. Weiters werden durch den Einsatz der Stufenbürsten zwei nicht gewollte Reibpartner auseinander gebürstet. Fremdartige Gegenstände, wie z.B.: Schuhe, Regenschirme, Taschen, Kunststoffsäcke oder andere Gegenstände werden vom Sockelblech mittels der Stufenbürsten weggebürstet, wobei die Stufenbürsten die Gegenstände aus dem Gefahrenbereich, also Sockelblech und Stufenspalt, schieben bzw. bürsten. Folglich wird ein Einzwicken oder Einkeilen von Gegenständen nicht möglich oder sehr stark verhindert. Die Benützung der Fahrtreppe wird dadurch wesentlich verbessert und die Sicherheit essentiell gesteigert.Such stage brushes positioned as described above provide a necessary contact prevention of objects with the base plate. The step brushes prevent the contact of objects with the base plates and at the same time the penetration of the objects into the gap between the base plate and the passing stage or step band. Furthermore, by using the step brushes two unwanted friction partners are brushed apart. Foreign objects, such as: shoes, umbrellas, bags, plastic bags or other objects are brushed away from the base plate using the step brushes, the step brushes push the objects from the danger area, ie base plate and step gap, or brush. Consequently, chewing or wedging objects is not possible or very much prevented. The use of the escalator is thereby significantly improved and security increased essential.
Die Bürsten lösen jeden Reibkontakt auf, bevor ein Eindringen in den Spalt zwischen den bewegten Stufen und dem fixierten Sockelblech erfolgen kann. Speziell bei den Übergangsradien wo nicht nur eine Relativbewegung zwischen den Stufen und dem Sockelblech vorhanden ist, sondern auch noch eine Relativbewegung zwischen zwei benachbarten Stufen erfolgt, nämlich dann wenn sich eine horizontale Trittstufe einer vor ihr laufenden Setzstufe in Aufwärtsbewegung nähert, wird durch die Bürsten jeden Reibkontakt in diesem kritischen Bereich zwischen Trittstufe und Setzstufe verhindert.The brushes release any frictional contact before they can penetrate into the gap between the moving steps and the fixed base plate. Especially when the transition radii where not only a relative movement between the steps and the base plate is present, but also a relative movement between two adjacent stages takes place, namely, when a horizontal tread approaching in front of her riser in upward motion, by the brushes each Frictional contact in this critical area between tread and riser prevented.
Die Vorrichtung im Patent
In einer bevorzugten Ausführungsform der Erfindung sind die Stufenbürsten entlang der ganzen Trittstufenkante in Normalrichtung zur Trittstufenfläche angeordnet.In a preferred embodiment of the invention, the step brushes are arranged along the entire tread edge in the normal direction to the tread surface.
Die erfindungsgemässen Bürsten werden also so orientiert montiert bzw. angeordnet, dass die Bürsten normal zur Trittstufenoberfläche sind und entlang des Sockelblechs hinausragen und dadurch das Sockelblech nicht berühren. Eine Berührung mit dem Sockelblech erfolgt nur dann wenn ein Gegenstand zum Reibungskontakt mit dem Sockelblech kommt. Bei dieser Ausführungsform der Erfindung wird auch jeder Reibkontakt zwischen zwei Gegenständen vor einem Eindringen in den Spalt, zwischen der beweglichen Stufe und den fixen Sockelblech, verhindert.The brushes according to the invention are thus mounted or arranged in such a way that the brushes are normal to the tread surface and project beyond the base plate and thus do not touch the base plate. A contact with the base plate takes place only when an object comes into frictional contact with the base plate. In this embodiment of the invention, any frictional contact between two objects is prevented from penetrating into the gap, between the movable step and the fixed base plate.
In einer zweiten bevorzugten Ausführungsform der Erfindung weisen die Stufen eine Setzstufenfläche mit mindestens einer Setzstufenkante auf, an der Stufenbürsten angeordnet sind.In a second preferred embodiment of the invention, the steps have a riser surface with at least one riser edge on which step brushes are arranged.
Die Setzstufenfläche ist die vordere annähernd vertikale Fläche der Fahrtreppenstufe. Oft ist sie gekrümmt bzw. gerundet bzw. konvex. Die Setzstufenkante ist die geometrische Linie, die die Setzstufenfläche abgrenzt und die unmittelbare Umgebung dieser geometrischen Linie auf der Setzstufenfläche.The riser surface is the front approximately vertical surface of the escalator step. Often it is curved or rounded or convex. The riser edge is the geometric line delimiting the riser surface and the immediate vicinity of this geometric line on the riser surface.
Vorteilhaft an diese Ausführungsform ist, dass die Gefahr des Eindringens eines Gegenstandes in den Luftspalt weiter reduziert wird.An advantage of this embodiment is that the risk of the penetration of an object into the air gap is further reduced.
In einer weiteren bevorzugten Ausführungsform der Erfindung sind die Stufenbürsten entlang der ganzen Setzstufenkante in Normalrichtung zur Setzstufenfläche angeordnet. Bei dieser Lösung berühren die vom Sockelblech weggerichteten Bürsten das Sockelblech nicht, weshalb keine Reibung entsteht und das Sockelblech und die Bürsten eine lange Lebensdauer aufweisen.In a further preferred embodiment of the invention, the step brushes are arranged along the entire setting step edge in the normal direction to the riser surface. In this solution, the directed away from the base plate brushes do not touch the base plate, which is why there is no friction and the base plate and the brushes have a long life.
In einer weiteren bevorzugten Ausführungsform der Erfindung bestehen die Stufenbürsten aus Kunststoffborsten oder Messingborsten oder verzinkte Stahlborsten. Durch den Einsatz dieser Werkstoffe wird die Reibkontaktverhinderung weiter erhöht. Die obengenannten Werkstoffe haben ausserdem den Vorteil zwei in Reibung befindliche Gegenstände leichter bzw. müheloser bzw. problemloser zu trennen.In a further preferred embodiment of the invention, the step brushes made of plastic bristles or brass bristles or galvanized steel bristles. By using these materials, the Reibkontaktverhinderung is further increased. The above-mentioned materials also have the advantage of separating two objects in friction more easily or effortlessly or more easily.
In einer weiteren bevorzugten Ausführungsform der Erfindung sind die Stufenbürsten aufgespritzt oder aufgeklebt oder mitgeschraubt oder eingeklebt oder eingeschnappt auf den Stufen befestigt. Kostengünstige und einfache übliche Herstellungsverfahren der Bürsten lassen sich somit verwenden.In a further preferred embodiment of the invention, the step brushes are sprayed or glued or screwed or glued or snapped fixed on the steps. Cost-effective and simple conventional production methods of the brushes can thus be used.
Vorteilhafterweise ist die Trittstufenkante ein separater mechanischer Kunststoffbauteil der Stufe und sind die Stufenbürsten umspritzt bzw. eingespritzt bzw. eingeklebt auf der Trittstufenkante befestigt. Die Stufenbürsten können somit separat mit dem Kunststoffbauteil, der die Trittstufenkante bildet, hergestellt werden. Der ganze Bauteil wird dann später auf eine schnelle und einfache Weise auf dem Stufenkörper montiert. Eine solche separate Trittstufenkante ist einfach demontierbar und ersetzbar.Advantageously, the tread edge is a separate mechanical plastic component of the step and the step brushes are molded or injected or glued attached to the tread edge. The step brushes can thus be made separately with the plastic component that forms the tread edge. The entire component is then later mounted on the step body in a quick and easy manner. Such a separate tread edge is easily removable and replaceable.
In einer Ausführungsform der Erfindung sind Stufenbürsten an einer Stufe für eine Fahrtreppe entlang der ganzen Trittstufenkante mit Normalrichtung zur Trittstufenfläche angeordnet.In one embodiment of the invention, stepping brushes are on one step for an escalator all the way around Tread edge with normal direction to the tread surface arranged.
Eine solche Stufe kann einfach und kostengünstig als Halbzeug produziert werden und dann schnell und einfach an einer Fahrtreppe eingesetzt werden.Such a stage can be easily and inexpensively produced as a semi-finished product and then quickly and easily be used on an escalator.
In einer letzten Ausführungsform der Erfindung wird eine Fahrtreppe mit Stufen, welche eine Trittstufenfläche mit einer Trittstufenkante aufweisen, modernisiert, in dem Stufenbürsten an der Trittstufenkante angebracht werden.In a final embodiment of the invention, an escalator with steps having a tread surface with a tread edge is modernized, in which tread brushes are attached to the tread edge.
Von den oben beschriebenen Vorteilen können auch herkömmliche Fahreinrichtungen durch diese Moderniesungsverfahren einfach und schnell profitieren.From the above-described advantages, even conventional driving devices can benefit easily and quickly by these modernization methods.

Bei einer Fahrtreppe mit einer Balustrade werden an allen Fahrtreppenstufen 1 Stufenbürsten 3 montiert. Sowohl auf der Trittstufe, wie auch auf der Setzstufe, befinden sich die Stufenbürsten 3. Die Stufenbürsten 3 werden links und rechts an der Fahrtreppenstufe 1 angebracht. Die Stufenbürsten 3 verhindern durch eine Kontaktminimierung ein Einklemmen oder Mitschleifen von Schuhen, Regenschirmen, Taschen, Kunststoffsäcken oder anderen Gegenständen. Sie verhindern ein Eindringen von allen Fremdelementen: Zeitungspapierstücke, Plastiktüten, Kieselsteine, Kleidungsstückefasern und gröberen Schmutz sowie Schnee und Eis.With an escalator with a balustrade, 1 step brushes 3 are mounted on all escalator steps. Stepped brushes 3 are located on the step as well as on the riser. Stepped brushes 3 are placed on
Der grosse Vorteil der Stufenbürsten 3 liegt in der fächerartigen und somit absperrenden Aufstellung. Der Stufenspalt wird verbarrikadiert und ein Erreichen der Fahrtreppenstufenseitenkante verunmöglicht. Ein weiterer Vorteil der Stufenbürsten 3 liegt, gegenüber festen Randelementen bzw. feststehenden Platten, in deren Flexibilität. Somit wird einem seitlichen Berühren durch das Schuhwerk biegsam ausgewichen und der fallweise benötigte Platzbedarf wird freigegeben.The big advantage of the step brushes 3 lies in the fan-like and therefore shut-off lineup. The step gap is barricaded and it is impossible to reach the escalator side edge. Another advantage of the step brushes 3, compared to fixed edge elements or fixed plates, in their flexibility. Thus, a sideways touching through the footwear is dodge flexible and the occasionally required space is released.
Die Stufenbürsten 3 verhindern wie ein dichter Wall aus Kunststoffborsten das Vordringen bzw. das Erreichen des Sockelblech-Stufenspaltes. Eine dichte, hermetische, undurchlässige Borstenbegrenzung befindet sich nun links und rechts der Fahrtreppenstufe 1.The step brushes 3 prevent like a dense wall of plastic bristles the penetration or reaching the base plate step gap. A dense, hermetic, impermeable bristle boundary is now located on the left and right of
Die Stufenbürsten 3 können aufgespritzt oder aufgeklebt oder mitgeschraubt oder eingeklebt oder eingeschnappt auf der Fahrtreppenstufe 1 befestigt werden.The step brushes 3 can be sprayed or glued or screwed or glued or snapped fixed on the
Solche Kunststoffkanten sind vorzugsweise gelb, um einen klaren sichtbaren Hinweis den Passagieren zu geben, dass ein Spalt dort vorhanden ist. Eine eindeutige Sichtbarkeit der Gefahr oder Achtung ist somit gegeben.Such plastic edges are preferably yellow to give a clear visual indication to the passengers that there is a gap. A clear visibility of danger or respect is thus given.
Die Stufenbürsten 3 werden also gemeinsam mit den gelben Kunststoffkanten 2 hergestellt und gemeinsam am Stufenkörper 1 montiert bzw. angeschraubt.The step brushes 3 are thus produced together with the yellow
Die Stufenbürsten 3 bilden eine Barriere bzw. Schranke zu den Passagieren und hemmen bzw. erschweren ein Berühren des Sockelbleches. Es kann keine Verbindung zum Sockelblechspalt hergestellt werden und ein Einzwicken oder Einkeilen oder Einquetschen ist unmöglich.The step brushes 3 form a barrier or barrier to the passengers and inhibit or make it difficult to touch the base plate. It can not be made a connection to the base plate gap and a chewing or wedging or pinching is impossible.
Die Stufenbürsten 3 entkoppeln somit die feststehenden (Sockelblech) vom den bewegten (Fahrtreppenstufe) Komponenten.The step brushes 3 thus decouple the fixed (base plate) from the moving (escalator step) components.
Ein Aneinandergleiten wird durch die Stufenbürsten 3 komplett vermieden. Weiters sind die Stufenbürsten 3 so kompakt ausgeführt, dass sie der Belastung durch den Personenverkehr standhalten.
Deshalb ist auch ein dauerhaftes, widerstandsfähiges, unempfindliches Bürstenmaterial zu verwenden, wie z.B. Kunststoffborsten oder Messingborsten oder verzinkte Stahldrahtborsten.
Die ausreichende Dimensionierung und Auslegung der Stufenbürsten 3 ist aufgrund der Passagierzahl und deren daraus folgenden Beanspruchungen gegeben.A sliding against each other is completely avoided by the step brushes 3. Furthermore, the step brushes 3 are designed so compact that they withstand the burden of passenger traffic.
Therefore, a durable, resistant, insensitive brush material should be used, such as plastic bristles or brass bristles or galvanized steel wire bristles.
The sufficient dimensioning and design of the step brushes 3 is given due to the number of passengers and their resulting stresses.
Nach einer bevorzugten Ausführung der Erfindung sind die Borsten der Bürsten gewellt. Das ist vorteilhaft, weil solche Borsten eine höhere Formstabilität und längere Lebensdauer aufweisen.According to a preferred embodiment of the invention, the bristles of the brushes are corrugated. This is advantageous because such bristles have a higher dimensional stability and longer life.
Nach einer weiteren Ausführung der Erfindung ist das Ende der Borsten der Stufenbürsten abgerundet. Das ist vorteilhaft, weil die Gefahr einer Verletzung der Passagiere bei Kontakt mit den Borsten vermindert wird.According to a further embodiment of the invention, the end of the bristles of the step brushes is rounded. This is advantageous because the risk of injury to the passengers upon contact with the bristles is reduced.
Die Wellenstruktur erhöht die mechanische Festigkeit der Bosten und ermöglicht eine bessere Verteilung der Kräfte, die durch Gegenstände oder Passagiere ausgeübt werden. Die Wellenstruktur stabilisiert die Borsten gegen eine Verbiegung schräg zur Längsachse verglichen mit den geraden Borsten. Wenn die geraden Borsten in der Längsachse gedrückt werden, verbiegen sie sich und können keine Gegenkraft mehr ausüben. Im Unterschied dazu nehmen die gewellten Borsten den Druck in Längsachse als Federspannung auf, welche in den Wellen gespeichert wird, halten die Borsten ihre Ausrichtung bei und werden nicht verbogen.The wave structure increases the mechanical strength of the bosts and allows a better distribution of the forces exerted by objects or passengers. The wave structure stabilizes the bristles against bending obliquely to the longitudinal axis compared to the straight bristles. When the straight bristles are pressed in the longitudinal axis, they bend and can no longer exert any counterforce. In contrast, the wavy bristles absorb the pressure in the longitudinal axis as spring tension stored in the shafts, the bristles maintain their alignment and are not bent.
Die gewellten Borsten verringern durch ihre Dichte massgeblich den Spalt bzw.
