Handläufe für Fahrtreppen, Fahrsteige für die Personenbeförderung und dergleichen haben wichtige Funktionen zu erfüllen. Sie müssen für die die Fahrtreppen und Fahrsteige benützenden Personen einen stabilen und sicheren Griff zur Verfügung stellen und derart flexibel ausgeführt sein, dass sie sich um die verschiedenen Antriebsrollen biegen und führen lassen. Darüber hinaus müssen Handläufe Spannungen von mehreren tausend Newton aushalten können.Handrails for escalators, moving walks for passenger transportation and the like have important functions to perform. You have to go for the escalators and People using moving walkways have a stable and secure grip and be designed so flexibly that they are different Bend the drive rollers and let them guide. They also need handrails Can withstand voltages of several thousand Newtons.

Eine Handlaufkonstruktion der eingangs genannten Art ist beispielsweise aus der US - A 5 255 772 bekannt. Die hier geoffenbarte Handlauftype mit C-förmigem Querschnitt weist einen Zugträger auf, welcher aus parallel zueinander in der Längsrichtung des Handlaufs verlaufenden Stahlcorden besteht, die in eine Gummimatrix eingebettet sind. Die Gleitlage besteht aus einem dicht gewebtem Material, beispielsweise aus Baumwolle, Polyamid oder Polyester, und hat ein gutes Gleiten des Handlaufs auf der Führungsschiene zu gewährleisten. Beidseitig des Zugträgers sind Verstärkungslagen angeordnet, die aus einem gewebten Material bestehen, dessen Kettfäden in der Querrichtung des Handlaufs, demnach im rechten Winkel zum Zugträger, orientiert sind. Die vereinzelt vorgesehenen Schußfäden dienen lediglich zum Zusammenhalt der Kettfäden.A handrail construction of the type mentioned at the outset is known, for example, from the US A 5 255 772 known. The type of handrail disclosed here with a C-shaped cross-section has a tension member, which consists of parallel to each other in the longitudinal direction of the Handrail made of steel cords, embedded in a rubber matrix are. The sliding layer consists of a tightly woven material, for example Cotton, polyamide or polyester, and has a good sliding handrail on the To ensure the guide rail. There are reinforcement layers on both sides of the tension member arranged, which consist of a woven material, the warp threads in the Transverse direction of the handrail, therefore at right angles to the tension member are. The weft threads provided are only used for cohesion the warp threads.

Durch den C-förmigen Querschnitt des Handlaufs wird die erforderliche Steifigkeit unterstützt. Die Lippenweite wird so abgestimmt, dass der Handlauf ohne zu großen Widerstand gleiten kann, wobei aber die Lippenweitentoleranz so klein zu sein hat, dass ein Einzwicken der Finger oder von Bekleidung nicht stattfinden kann. Meist tendieren Handläufe bekannter Konstruktionen entweder zu einer Aufweitung des Lippenabstandes, was zu einem Einzwicken der Finger oder von Bekleidung führen kann, oder sie tendieren dazu, enger zu werden. In letzterem Fall kann dies zur Reibung des Handlaufs an der Schiene, zu Überhitzung und in weiterer Folge zur Zerstörung des Handlaufs führen.The C-shaped cross section of the handrail provides the required rigidity supported. The lip width is adjusted so that the handrail is not too big Resistance can slide, but the lip width tolerance has to be so small that the fingers or clothing cannot pinch. Most of time handrails of known constructions tend to either expand the Lip distance, which can lead to pinching of the fingers or clothing can, or they tend to get narrower. In the latter case, this can lead to Friction of the handrail on the rail, to overheating and subsequently to Destruction of the handrail.

Die Erfindung hat sich daher nun die Aufgabe gestellt, einen Handlauf für Fahrtreppen und Fahrsteige für Personen mit gegenüber den bekannten Konstruktionen verbesserten dynamischen Eigenschaften und verbesserter dimensioneller Stabilität bei längerer Lebensdauer zu entwickeln, der die erwähnten Probleme nicht aufweist.The object of the invention is therefore a handrail for escalators and moving walks for people with compared to the known constructions improved dynamic properties and dimensional stability to develop with a longer lifespan that does not have the problems mentioned.

Gelöst wird die gestellte Aufgabe erfindungsgemäß dadurch, zumindest eine der Verstärkungslagen eine Gummilage mit homogen verteilten Kurzfasern ist, die eine Vorzugsorientierung besitzen und gegenüber der Längsrichtung des Handlaufs unter einem von 0° abweichenden Winkel, verlaufen.According to the invention, the object is achieved by at least one of the Reinforcement layers is a rubber layer with homogeneously distributed short fibers, the one Have preferred orientation and under the longitudinal direction of the handrail an angle deviating from 0 °.

Durch die gegenständliche Erfindung wird ein Handlauf mit gegenüber den bekannten Konstruktionen höherer Quersteifigkeit, höherer Längsflexibilität, verbesserter Dimensionsstabilität und steiferen Lippen zur Verfügung gestellt. Das für die Verstärkungslagen erfindungsgemäß eingesetzte homogen mit Kurzfasern versehene Material verhindert das Auftreten von unterschiedlichen Spannungen, die bei konventionellen Handläufen während der Beanspruchung im Bereich der Übergänge von Textil zu Gummi entstehen. Dabei sind die Verstärkungslagen im Handlauf so positioniert, dass die Kurzfasern unter einem von 0° abweichenden Winkel zur Erstreckung des Zugträgers verlaufen. Eine erfindungsgemäße Verstärkungslage beinhaltet auch keine Kettfäden, die in konventionell aufgebauten Handläufen in den Verstärkungslagen aus gewebtem Material enthalten sind. Das Fehlen der Kettfäden verleiht einem erfindungsgemäß aufgebauten Handlauf eine ausgezeichnete Elastizität in Längsrichtung bei gleichzeitig hoher Quersteifigkeit. Darüber hinaus ist bei erfindungsgemäßen Handläufen die Lippenweitenänderung sowohl bei einer Positivbiegung als auch bei einer Biegung über den Handlaufrücken (Negativbiegung) wesentlich geringer als bei herkömmlich aufgebauten Handläufen. Erfindungsgemäß aufgebaute Handläufe sind einfach herzustellen, besitzen eine gegenüber den bekannten Konstruktionen erheblich höhere Lebensdauer und sind insgesamt sicherer im Betrieb als die bekannten Konstruktionen.Due to the present invention, a handrail is compared to the known Constructions of higher transverse stiffness, greater longitudinal flexibility, improved Dimensional stability and stiffer lips are provided. That for them Reinforcement layers used according to the invention are provided homogeneously with short fibers Material prevents the occurrence of different tensions when conventional handrails during stress in the area of the transitions from textile to rubber. The reinforcement layers in the handrail are like this positioned that the short fibers at an angle other than 0 ° to the Extension of the tension member. A reinforcement layer according to the invention also does not contain any warp threads that are in the conventional handrails in the Reinforced layers of woven material are included. The lack of warp threads imparts excellent elasticity to a handrail constructed according to the invention in the longitudinal direction with high transverse rigidity. In addition, at handrails according to the invention the lip width change both in one Positive bend as well as a bend over the back of the handrail (negative bend) much lower than with conventionally constructed handrails. According to the invention constructed handrails are easy to manufacture, have a compared to the known designs significantly longer life and are overall safer in operation than the known constructions.

Gemäß einer bevorzugten Ausführungsform der Erfindung sind die Kurzfasern in den Verstärkungslagen derart orientiert, dass sie gegenüber der Längsrichtung des Handlaufs unter einem Winkel, der um mindestens 30°, insbesondere um mindestens 45°, von der Längsrichtung des Handlaufs abweicht, verlaufen. Eine Orientierung der Kurzfasern in diesen Bereichen ist sowohl für die Elastizität in Längsrichtung als auch eine hohe Quersteifigkeit von Vorteil.According to a preferred embodiment of the invention, the short fibers are in the Reinforcement layers oriented such that they are opposite to the longitudinal direction of the Handrail at an angle that is at least 30 °, in particular at least 45 °, deviates from the longitudinal direction of the handrail. An orientation of the Short fibers in these areas is both for longitudinal elasticity as well a high transverse rigidity is an advantage.

Je nach Anforderung und Einsatzzweck kann ein erfindungsgemäßer Handlauf unterschiedlich ausgeführt werden. Insbesondere kann bzw. können auf einer oder auf beiden Seiten der Zugträgerlage jeweils zumindest je eine, insbesondere je zwei, mit Kurzfasern versehene Verstärkungslage(n) angeordnet werden.Depending on the requirement and intended use, a handrail according to the invention can be executed differently. In particular, can or can on or on on both sides of the tension member at least one, in particular two, with Short fibers provided reinforcement layer (s) are arranged.

Die Steifigkeit des erfindungsgemäßen Handlaufs wird dadurch günstig beeinflußt, wenn sich die Kurzfasern in benachbarten Verstärkungslagen kreuzen und mit der Längsrichtung des Handlaufs vorzugsweise gleich große Winkel einschließen. Alternativ dazu kann auch eine Ausführung getroffen werden, bei der die Kurzfasern in benachbarten Verstärkungslagen parallel zueinander verlaufen.The rigidity of the handrail according to the invention is favorably influenced by if the short fibers cross in adjacent reinforcement layers and with the Incline preferably equal angles in the longitudinal direction of the handrail. Alternatively, an embodiment can also be made in which the short fibers in neighboring reinforcement layers run parallel to each other.

Zum Erziehlen der erwünschten Quersteifigkeit, der Längsflexibilität und der Dimensionsstabilität ist es dabei günstig, wenn der Anteil an Kurzfasern zwischen 10 und 40 Gewichtsteile, insbesondere zwischen 15 und 30 Gewichtsteile, bezogen auf 100 Gewichtsteile Kautschuk in der Mischung, beträgt.To achieve the desired transverse stiffness, longitudinal flexibility and Dimensional stability is favorable if the proportion of short fibers is between 10 and 40 parts by weight, especially between 15 and 30 parts by weight, based on 100 parts by weight of rubber in the mixture.

Was das Material für die Kurzfasern betrifft, so können diese aus synthetischem Material, wie Nylon, Polyester, Polyvinylalkohol, aromatischem Polyamid, Kohlenstoff, aus mineralischem Material wie Glas oder aus natürlichem Material, beispielsweise Baumwolle, bestehen. Die eingesetzten Kurzfasern können dabei auch ein Fasernmix aus Fasern unterschiedlichen Materials sein. Die Steifigkeit der Verstärkungslagen kann somit durch die Wahl der Faserart und des Mischverhältnisses möglicher unterschiedlicher Fasern mitbestimmt werden. As for the material for the short fibers, these can be made of synthetic Material such as nylon, polyester, polyvinyl alcohol, aromatic polyamide, carbon, from mineral material such as glass or from natural material, for example Cotton. The short fibers used can also be a fiber mix be made of fibers of different materials. The rigidity of the reinforcement layers can be made possible by the choice of fiber type and the mixing ratio different fibers can be determined.

Auch das Verhältnis der Länge der Fasern zum Durchmesser der Fasern ist mitbestimmend für die Steifigkeit der Lagen. Dieses Verhältnis sollte für die eingesetzten Fasern zwischen 50 und 300 betragen.Also the ratio of the length of the fibers to the diameter of the fibers is contributes to the rigidity of the layers. This ratio should be for the fibers used are between 50 and 300.

Bei der in den beiden Zeichnungsfiguren dargestellten Konstruktion sind zwischen der Gummiabdecklage 2 und der Gleitlage 3 drei weitere Lagen angeordnet, von denen die mittlere eine nur im Mittelteil 1a verlaufende Gummilage 4 ist, in die Stahlcorde 4a eingebettet sind, die in der Längsrichtung des Handlaufs 1 verlaufen. Bei einer weiteren möglichen Ausführungsform, die hier nicht dargestellt ist, kann die Lage 4 bis in die Lippenbereiche verlaufen, wird dann jedoch dort ohne Festigkeitsträger ausgeführt. Die Stahlcorde 4a bilden den Zugträger des Handlaufes 1. Dabei ist normalerweise und wie auch in den Zeichnungsfiguren dargestellt eine einzige Lage von Stahlcorden 4a vorgesehen, die in der Lage 4 nebeneinander liegend verlaufen.In the construction shown in the two figures, between the Rubber cover layer 2 and the sliding layer 3 arranged three further layers, one of which the middle one is a rubber layer 4 running only in the middle part 1a, into the steel cords 4a are embedded, which run in the longitudinal direction of the handrail 1. At a Another possible embodiment, which is not shown here, the position 4 to run into the lip areas, but then there is no reinforcement executed. The steel cords 4a form the tension member of the handrail 1 normally and as shown in the drawing figures, a single layer provided by steel cords 4a, which in the layer 4 run side by side.

Beidseitig der Zugträgerlage 4 und jeweils zwischen der Abdecklage 2 und der Gleitlage 3 sowie in die Lippenbereiche 1b verlaufend ist je eine erfindungsgemäß ausgeführte Verstärkungslage 5 vorgesehen. Die Verstärkungslagen 5 betten zwischen sich die Zugträgerlage 4 ein, beidseitig der Lage 4 bzw. in den Lippenbereichen 1b bilden sie eine einheitliche Lage. Die Lagen 5 bestehen aus einer Gummimischung, in die Kurzfasern 6 eingebettet sind. Dabei besitzen die Kurzfasern 6 eine bevorzugte Orientierung, sie sind weitgehend in einer einzigen Richtung orientiert, wobei die Lagen 5 beim dargestellten Ausführungsbeispiel so in den Handlauf 1 eingebettet sind, dass die Kurzfasern 6 in der Querrichtung des Handlaufs 1 verlaufen, demnach unter einem rechten Winkel zur Längsrichtung und zur Ausrichtung des Zugträgers angeordnet sind.On both sides of the tension member layer 4 and between the cover layer 2 and the Sliding layer 3 and extending into the lip areas 1b are each one according to the invention executed reinforcement layer 5 is provided. The reinforcement layers 5 beds between them the tension member layer 4, on both sides of the layer 4 or in the Lip areas 1b form a uniform position. The layers 5 consist of a Rubber mixture in which short fibers 6 are embedded. The short fibers 6 a preferred orientation, they are largely oriented in a single direction, the layers 5 in the illustrated embodiment in the handrail 1 embedded that the short fibers 6 run in the transverse direction of the handrail 1, therefore at a right angle to the longitudinal direction and the orientation of the Tension member are arranged.

Je nach Ausführung oder auch Einsatzzweck werden die Lagen 5 mit entsprechender Dicke ausgeführt. Im fertigen, vulkanisierten Handlauf hat eine Verstärkungslage 5 üblicherweise eine Dicke zwischen 0,8 und 5 mm, insbesondere bis zu 3 mm. Die rohen Platten aus der faserverstärkten Mischung werden bei einer Herstellung durch Kalandrieren in einer Dicke von 0,5 bis 0,8 mm erstellt, was eine gute Orientierung der Fasern gewährleistet. Um im fertigen Handlauf eine dickere Verstärkungslage 5 zu erhalten werden mehrere, insbesondere bis zu vier, dünne kalandrierte Platten entweder nach dem Kalandrieren doubliert oder beim Aufbau des Handlaufs 1 übereinander gelegt. Bei dünnen Lagen 5, wenn diese eine Dicke von etwa 0,8 mm besitzen, kann es erforderlich sein, die an die Zugträgerlage 4 unmittelbar anschließenden Querschnittsbereiche mit gesonderten Streifen aus der Mischung der Lagen 5 auszufüllen. Bei dickeren Lagen 5 reicht im Allgemeinen deren Volumen bereits aus, diese Querschnittbereiche adäquat aufzufüllen. Was die Orientierung der Fasern in den Auffüllstreifen betrifft, würde beim vorliegenden Ausführungsbeispiel diese der Orientierung der Fasern in den Lagen 5 entsprechen.Depending on the design or the intended use, the layers 5 are provided with a corresponding Running thickness. In the finished, vulcanized handrail there is a reinforcement layer 5 Usually a thickness between 0.8 and 5 mm, in particular up to 3 mm. The raw panels from the fiber-reinforced mixture are made during a manufacturing process Calendering in a thickness of 0.5 to 0.8 mm created, which is a good orientation of the Fibers guaranteed. To a thicker reinforcement layer 5 in the finished handrail several, in particular up to four, thin calendered plates are obtained either relined after calendering or when setting up the handrail 1 superimposed. In the case of thin layers 5, if these have a thickness of approximately 0.8 mm own, it may be necessary to directly on the tension member layer 4 Subsequent cross-sectional areas with separate strips from the mixture of Fill in layers 5. With thicker layers 5, their volume is generally sufficient already fill out these cross-sectional areas adequately. As for the orientation of the Fibers in the filler strips would be in the present embodiment these correspond to the orientation of the fibers in the layers 5.

Anhand der in der nachfolgenden Tabellen enthaltenen zwei Mischungsbeispiele für eine Kautschukmischung zur Herstellung von Verstärkungslagen 5 werden weitere besondere Merkmale derselben näher erläutert. Die zu den einzelnen Komponenten angegebenen Anteile sind Gewichtsteile, die jeweils auf 100 Gewichtsteile Kautschuk in der Mischung bezogen sind. Mischungsbeispiel 1: BESTANDTEIL ANTEIL CR Schwefel modifiziert 100 Ruß N 550 45 Baumwollkurzfasern 15 Nylonkurzfasern 5 Weichmacher 6 Alterungsschutzmittel 3 MgO 3 ZnO 6 Beschleuniger 0,5 Schwefel 1 Vernetzer 0,5 Mischungsbeispiel 2: BESTANDTEIL ANTEIL SBR 70 NR 30 Ruß N330 30 Baumwollkurzfasern 10 Nylonkurzfasern 5 PVA-Kurzfasern 5 Aromatischer Weichmacher 5 Alterungsschutzmittel 1,5 Stearinsäure 1 ZnO 6 Beschleuniger 1 Schwefel 4 On the basis of the two mixture examples for a rubber mixture for the production of reinforcement layers 5 contained in the following tables, further special features thereof are explained in more detail. The proportions given for the individual components are parts by weight, each based on 100 parts by weight of rubber in the mixture. Mixture example 1: COMPONENT PROPORTION OF CR modified sulfur 100 Carbon black N 550 45 Cotton short fibers 15 Nylon short fibers 5 softener 6 Anti-aging agents 3 MgO 3 ZnO 6 accelerator 0.5 sulfur 1 crosslinkers 0.5 Mixture example 2: COMPONENT PROPORTION OF SBR 70 NO 30 Carbon black N330 30 Cotton short fibers 10 Nylon short fibers 5 PVA short fibers 5 Aromatic plasticizer 5 Anti-aging agents 1.5 stearic acid 1 ZnO 6 accelerator 1 sulfur 4

Vom Polymer her basiert die Mischung gemäß Beispiel 1 auf Polychloropren-Kautschuk, die Mischung gemäß Beispiel 2 auf Styrolbutadienkautschuk und Naturkautschuk, wobei es sich hier lediglich um Beispiele und somit um bevorzugte Kautschuktypen handelt. Dabei kann in Beispiel 2 der Anteil an SBR zwischen 30 und 80 Gewichtsteile und der Anteil an Naturkautschuk demnach zwischen 20 und 70 Gewichtsteilen betragen. Beide Mischungen enthalten ferner Weichmacher, dessen Anteil bis zu 20 Gewichtsteile betragen kann. Die Kautschukmischungen enthalten ferner die üblichen Zusätze, wie Alterungsschutzmittel, Magnesiumoxid, Stearinsäure, Zinkoxid, Beschleuniger, Schwefel und gegebenenfalls Vernetzer, wobei diese Zusätze in den üblichen Mengen beigemengt sind. Der Rußanteil kann zwischen 20 und 70 Gewichtsteile betragen.In terms of polymer, the mixture according to Example 1 is based on polychloroprene rubber, the mixture according to Example 2 on styrene butadiene rubber and Natural rubber, which are only examples and therefore preferred Rubber types. In example 2, the proportion of SBR can be between 30 and 80 parts by weight and the proportion of natural rubber between 20 and 70 Parts by weight. Both mixtures also contain plasticizers Proportion can be up to 20 parts by weight. The rubber compounds contain furthermore the usual additives, such as anti-aging agents, magnesium oxide, stearic acid, Zinc oxide, accelerator, sulfur and optionally crosslinking agent, these additives are added in the usual amounts. The amount of soot can be between 20 and 70 Parts by weight.

Was die oben erwähnten Kurzfasern 6 betrifft, enthält die Kautschukmischung gemäß Mischungsbeispiel 1 Nylonkurzfasern in einem Anteil von 5 Gewichtsteilen und Baumwollkurzfasern in einem Anteil von 15 Gewichtsteilen, jeweils bezogen auf 100 Gewichtsteile Kautschuk in der Mischung. Die Mischung gemäß Mischungsbeispiel 2 enthält ein Gemisch aus Baumwollkurzfasern (10 Gewichtsteile), Nylonkurzfasern (5 Gewichtsteile) und PVA-Kurzfasern (5 Gewichtsteile). Es kommen daher neben Fasern aus synthetischem Material, wie Kohlenstoff, Nylon, Polyester und aromatischen Polyamid (Kevlar) auch Fasern aus einem mineralischen Material wie Glas und natürliche Fasern, wie Baumwolle, in Frage. Der Gesamtanteil an Fasern in der Mischung wird zwischen 10 und 40 Gewichtsteilen, insbesondere 15 bis 30 Gewichtsteile, gewählt. Dabei können Fasern unterschiedlichen Materials in Kombination miteinander beigemengt werden, es kann aber auch nur ein Fasertyp eingesetzt werden. Die Länge der in den Verstärkungslagen 5 eingebetteten Fasern beträgt im allgemeinen zwischen 1 und 12 mm. Dabei ist insbesondere auch das Verhältnis der Länge der Fasern zum Durchmesser der Fasern mitbestimmend für die Steifigkeit der Lagen 5. Dieses Verhältnis sollte für die eingesetzten Fasern zwischen 50 und 300 betragen.With regard to the short fibers 6 mentioned above, the rubber mixture according to FIG Mixture example 1 short nylon fibers in a proportion of 5 parts by weight and Cotton short fibers in a proportion of 15 parts by weight, based in each case on 100 Parts by weight of rubber in the mixture. The mixture according to mixture example 2 contains a mixture of short cotton fibers (10 parts by weight), short nylon fibers (5th Parts by weight) and PVA short fibers (5 parts by weight). It therefore comes alongside fibers made of synthetic material such as carbon, nylon, polyester and aromatic Polyamide (Kevlar) also fibers made from a mineral material such as glass and natural fibers, such as cotton. The total percentage of fibers in the Mixture is between 10 and 40 parts by weight, especially 15 to 30 parts by weight Parts by weight, selected. Fibers of different materials can be used Combination can be added to each other, but only one type of fiber can be used be used. The length of the fibers embedded in the reinforcement layers 5 is generally between 1 and 12 mm. This is particularly important Ratio of the length of the fibers to the diameter of the fibers Stiffness of the layers 5. This ratio should be between for the fibers used 50 and 300.

Die Steifigkeit der faserverstärkten Lagen 5 kann somit durch die Wahl der Faserart, des Mischverhältnisses möglicher unterschiedlicher Fasern, des Anteil an Fasern, der Länge der Fasern und des Verhältnisses Länge zu Durchmesser bestimmt bzw. eingestellt werden. Die nach der Vulkanisation aus solchen Kautschukmischungen entstehende fertige Verstärkungslage 5 besitzt eine Härte von mindestens 75 Shore A, insbesondere von mindestens 80 Shore A.The rigidity of the fiber-reinforced layers 5 can thus be determined by the choice of the type of fiber, the mixing ratio of possible different fibers, the proportion of fibers, the Length of the fibers and the ratio of length to diameter determined or can be set. That after vulcanization from such rubber compounds resulting reinforcement layer 5 has a hardness of at least 75 Shore A, especially at least 80 Shore A.

Die Fasern können unbeschichtet oder gummifreundlich beschichtet, beispielsweise RFL (Resorcin-Formaldehyd-Latex)-beschichtet, eingesetzt werden. Die Beschichtung hat den Zweck, die Haftung zwischen Fasermaterial und Gummimatrix zu verbessern. Die der rohen Kautschukmischung beigemischten Kurzfasern 6 werden beispielsweise durch den Kalandriervorgang in eine bestimmte Richtung orientiert. Eine gute Orientierung der Fasern in der Gummimischung erreicht man dabei im allgemeinen bei einem Kalandrieren der Mischung in einer Dicke von 0,5 bis 0,8 mm Dicke. Um dickere Lagen zu erhalten, wird die kalandrierte Lage mehrschichtig eingesetzt. Auch Extrudieren durch eine Breitschlitzdüse ist dazu geeignet, die Faserorientierung zu erreichen.The fibers can be uncoated or rubber-friendly coated, for example RFL (resorcinol-formaldehyde latex) -coated, can be used. The coating has the purpose of improving the adhesion between the fiber material and the rubber matrix. The short fibers 6 added to the raw rubber mixture are, for example oriented in a certain direction by the calendering process. A good Orientation of the fibers in the rubber mixture is generally achieved calendering the mixture to a thickness of 0.5 to 0.8 mm. To thicker ones To obtain layers, the calendered layer is used in multiple layers. Also Extruding through a slot die is suitable for increasing the fiber orientation to reach.

Beim Ausführungsbeispiel gemäß den Zeichnungsfiguren ist jeweils ober- und unterhalb der den Zugträger beinhaltenden Lage 4 je eine erfindungsgemäße Verstärkungslage 5 mit Kurzfasern 6 vorgesehen. Die Anzahl an bzw. die Gesamtdicke der Verstärkungslagen 5 werden einerseits von der Steifigkeit einer einzelnen Lage 5 und andererseits von der zu erreichenden Quersteifigkeit bestimmt.In the embodiment according to the drawing figures, top and below the layer 4 containing the tension member, one according to the invention Reinforcement layer 5 provided with short fibers 6. The number of or the The total thickness of the reinforcement layers 5 is determined by the rigidity of one individual layer 5 and on the other hand determined by the transverse rigidity to be achieved.

Wird nun, wie dargestellt, jeweils eine Lage 5 ober- und unterhalb der den Zugträger aufweisenden Lage 4 eingesetzt, erfolgt deren Anordnung bevorzugt derart, dass die Kurzfasern 6 unter einem rechten Winkel zur Längsrichtung des Handlaufs 1 bzw. des Zugträgers verlaufen. In jedem Fall wird die Ausrichtung der Kurzfasern 6 so gewählt, dass sie einen von 0° abweichenden Winkel mit der Längsrichtung des Handlaufs 1 einschließen. Von besonderem Vorteil ist es dabei, wenn der Winkel um mindestens 30°, insbesondere mindestens 45°, von der Längsrichtung abweicht.Now, as shown, a layer 5 above and below the tension member having layer 4 used, their arrangement is preferably such that the Short fibers 6 at a right angle to the longitudinal direction of the handrail 1 and the Tension member run. In any case, the orientation of the short fibers 6 is chosen so that it is at an angle other than 0 ° with the longitudinal direction of the handrail 1 lock in. It is particularly advantageous if the angle is at least 30 °, in particular at least 45 °, deviates from the longitudinal direction.

Werden beispielsweise jeweils zwei Lagen 5 ober- und unterhalb der Lage 4 vorgesehen, ist es von Vorteil, wenn jeweils die beiden oberhalb oder unterhalb der Lage 4 vorgesehenen Verstärkungslagen 5 so im Handlauf 1 positioniert werden, dass die Kurzfasern 6 der einen Lage 5 unter einem spitzen Winkel zur Längsrichtung des Handlaufs 1 orientiert sind und die zweite Verstärkungslage 5 derart eingesetzt wird, dass ihre Kurzfasern 6 unter einem vorzugsweise gleich großem, bezüglich der Längsrichtung jedoch in die andere Richtung weisenden Winkel verlaufen. Dies ergibt eine kreuzende Anordnung der Kurzfasern 6 in diesen beiden benachbarten Lagen 5. Bezüglich der beiden weiteren Lagen 5 kann die Orientierung der Kurzfasern 6 so fortgesetzt werden, dass in den Lippenbereichen 1b, wo Lagen 5 aneinander anschließen, wieder eine kreuzende Anordnung gegeben ist. Es kann jedoch die Positionierung sämtlicher Lagen 5 oder nur von einigen Lagen 5 so erfolgen, dass ihre Kurzfasern 6 quer zur Längsrichtung des Handlaufs 1 verlaufen.For example, if there are two layers 5 above and below the layer 4 provided, it is advantageous if the two above or below the Layer 4 provided reinforcement layers 5 are positioned in the handrail 1 that the short fibers 6 of one layer 5 at an acute angle to the longitudinal direction of the Handrail 1 are oriented and the second reinforcement layer 5 is used in such a way that their short fibers 6 under a preferably the same size, in terms of However, the longitudinal direction is in the opposite direction. This results in a crossing arrangement of the short fibers 6 in these two adjacent layers 5. With regard to the two further layers 5, the orientation of the short fibers 6 can be like this continue that in the lip areas 1b, where layers 5 meet connect, there is again a crossing arrangement. However, it can Position all layers 5 or only a few layers 5 so that their Short fibers 6 run transversely to the longitudinal direction of the handrail 1.

Erfindungsgemäße Verstärkungslagen 5 bilden homogen aufgebaute Verstärkungslagen, die dem Handlauf 1 eine ausgezeichnete Elastizität in Längsrichtung bei gleichzeitig hoher Quersteifigkeit verleihen. Dieses homogene Verstärkungsmaterial oberhalb und unterhalb des Zugträgers verhindert das Auftreten von unterschiedlichen Spannungen, wie es beispielsweise bei konventionellen Handläufen durch die Übergänge von Textil zu Gummi während der Beanspruchung der Fall sein kann, wodurch bei erfindungsgemäßen Handläufen eine größere Lebensdauer erreicht wird. Lippenweitenänderungen sowohl bei Positivbiegung als auch bei Biegung über den Handlaufrücken (Negativbiegung) sind durch das Fehlen von Einlagen-Kettfäden auf ein Minimum beschränkt. Es ist ferner ein Stauchen der Lagen, wie es ebenfalls bei herkömmlich aufgebauten Handläufen eintreten kann, durch die neue Konstruktion ausgeschlossen. Auch das Austreten der Gewebeeinlagen an die Gummioberfläche, wie es bei konventionellen Konstruktionen auftreten kann, kann bei erfindungsgemäß ausgeführten Handläufen nicht mehr stattfinden.Reinforcement layers 5 according to the invention form homogeneously constructed Reinforcement layers that give the handrail 1 excellent elasticity Longitudinal direction with high transverse rigidity. This homogeneous Reinforcement material above and below the tension member prevents the occurrence of different voltages, as is the case with conventional Handrails through the transitions from textile to rubber during use may be the case, which means a larger one in the handrails according to the invention Lifetime is reached. Lip width changes both with positive bend and even when bending over the back of the handrail (negative bend) are due to the lack of interlining warp threads to a minimum. It is also an upsetting of the Positions, as can also occur with conventionally constructed handrails, excluded by the new construction. The leakage of the Fabric inlays on the rubber surface, as is the case with conventional constructions can no longer occur in handrails designed according to the invention occur.

Ein weiterer, bedeutender Vorteil der neuen Konstruktion ist beim Aufbau des Stoßes gegeben. Gewebeüberlappungen, die bei herkömmlich aufgebauten Handläufen eine Inhomogenität und Schwachstelle des Handlaufs darstellen, fehlen bei der erfindungsgemäßen Konstruktion. Die Stoßstellen werden so ausgeführt, dass die erfindungsgemäßen Verstärkungslagen 5 in einem Winkel von 30 bis 90° nur Längsrichtung stumpf oder überlappend gestoßen werden, wobei während der Vulkanisation die Stoßstelle verfließt und keine inhomogene Stelle im Handlauf bilden kann. Auch die bei herkömmlichen Konstruktionen mit Textileinlagen oft auftretenden Probleme mit der Feuchtigkeitsaufnahme entfallen bei der erfindungsgemäßen Konstruktion. Another important advantage of the new construction is the construction of the joint given. Tissue overlaps, which is a common handrail The inhomogeneity and weak point of the handrail are missing in the construction according to the invention. The joints are designed so that the Reinforcement layers 5 according to the invention only at an angle of 30 to 90 ° Longitudinally butt or overlapping, while during the Vulcanization fuses the joint and does not form an inhomogeneous point in the handrail can. Even those that often occur with conventional constructions with textile inserts Problems with moisture absorption are eliminated in the invention Construction.

Die besonders hohe Härte des faserverstärkten Gummimaterials verleiht dem Handlauf eine hohe Quersteifigkeit, die sehr hohe Gummimischungsviskosität verhindert ein Durchdringen des Gummimaterials durch die Gleitlage, was bei konventionellen Handläufen zu einer Erhöhung der Reibung der Gleitlage an der Führungsschiene führen kann.The particularly high hardness of the fiber-reinforced rubber material gives this Handrail a high transverse rigidity, the very high rubber compound viscosity prevents penetration of the rubber material through the sliding layer, which at conventional handrails to increase the friction of the sliding position on the Can guide rail.
