Description

Handlauf für Fahrsteige, Fahrtreppen und dergleichen Handrail for moving walks, escalators and the like
Die Erfindung betrifft einen auf ein Führungselement montierbaren Handlauf für Fahrsteige, Fahrtreppen oder dergleichen der im Oberbegriff des Anspruchs 1 ge- nannten Gattung.The invention relates to a mountable on a guide element handrail for moving walks, escalators or the like called in the preamble of claim 1 genus.
Derartige Handläufe sind bereits bekannt (EP 0530944A1 , DE 1756354A, DE 1939241 A und DE 2129582A). Dabei hat sich gezeigt, dass sich die Quer- schnittsmaße der Handläufe über die Lebensdauer im Betrieb an den Fahrtrep- pen, Fahrsteigen und dergleichen durch dynamische Belastungen infolge abwechselnder positiver und negativer Biegungen des Handlaufs während des Durchlaufs durch Fahrtreppen, Fahrsteige oder dergleichen aufgrund von insbesondere Schrumpf- und Verzugserscheinungen ändern. Um diese Probleme zu vermeiden, ist es bekannt, solche Materialien und Einlagen einzubauen, die das Schwundmaß innerhalb kleiner Grenzen halten. Derartige Handläufe verlangen jedoch ein ausreichendes Spiel in Bezug zu den Flächen der Führungselemente und dessen Führungssockels, damit die Reibung und somit die Antriebskräfte für das Fortbewegen der Handläufe auf dem Führungselement nicht zu groß werden. Darüber hinaus ist auch darauf zu achten, dass Spalte, in welche Personen beim Benutzen von Fahrtreppen am Handlauf eingreifen könnten, nicht zu Verletzungen führen.Such handrails are already known (EP 0530944A1, DE 1756354A, DE 1939241 A and DE 2129582A). It has been shown that the cross-sectional dimensions of the handrails over the life in operation on the escalators, moving walkways and the like due to dynamic loads due to alternating positive and negative bends of the handrail during the passage through escalators, moving walks or the like due in particular Change shrinkage and distortion symptoms. To avoid these problems, it is known to incorporate such materials and inserts that keep the shrinkage within small limits. However, such handrails require sufficient clearance relative to the surfaces of the guide elements and its guide base so that the friction and thus the driving forces for moving the handrails on the guide element are not too large. In addition, care must be taken to ensure that gaps in which people could interfere when using escalators on the handrail, do not lead to injury.
Der Erfindung liegt die Aufgabe zugrunde, den Handlauf dahingehend zu verbessern, dass über die gesamte Lebensdauer ein sicherer und normgerechter Betrieb unter Beachtung von Sicherheitsbestimmungen möglich ist, ohne dass zu hohe Antriebskräfte zum Antrieb des Handlaufs aufgewendet werden müssen. Diese Aufgabe soll möglichst auch mit geringem Materialaufwand gelöst werden können. Die Erfindung ist im Anspruch 1 gekennzeichnet und in den Unteransprüchen sind weitere Ausbildungen der Erfindung beansprucht.The invention has for its object to improve the handrail to the effect that over the entire life of a safe and standard-compliant operation in compliance with safety regulations is possible without too high driving forces must be expended to drive the handrail. This task should be possible solved with low material costs. The invention is characterized in claim 1 and in the dependent claims further embodiments of the invention are claimed.
In der Zeichnung ist eine bevorzugte Ausbildungsform der Erfindung schematisch dargestellt.In the drawing, a preferred embodiment of the invention is shown schematically.
Bei der Erfindung wird der lichte Abstand C der Enden der gebogenen Ränder des Handlaufs, der aus dem gesamten Spaltmaß C1 + C2 zuzüglich der Breite X des Führungssockels an der betreffenden Stelle besteht, derart gewählt, dass das ge- samte Spaltmaß C1 + C2 unter Berücksichtigung der Toleranzen der Breite X des Führungssockels und der sich im Betrieb des Handlaufs ergebenden Schrumpfund Verzugserscheinungen 8 mm nicht überschreitet. Die lichte Weite A der gebogenen Ränder 4 soll derart um ein gesamtes Spaltmaß A1 + A2 größer gewählt sein als die Breite Y des Führungselements an dessen seitlichen Rippen, dass das gesamte Spaltmaß A1 + A2 unter Berücksichtigung der Toleranzen der Breite Y des Führungselements an den Enden der Rippen und der sich im Betrieb des Handlaufs ergebenden Schrumpf- und Verzugserscheinungen 8 mm nicht überschreitet.In the invention, the clear distance C of the ends of the curved edges of the handrail, which consists of the total gap dimension C1 + C2 plus the width X of the guide base at the relevant location, is selected such that the total gap dimension C1 + C2 is taken into account the tolerances of the width X of the guide base and the resulting in operation of the handrail shrinkage and distortion phenomena does not exceed 8 mm. The clear width A of the curved edges 4 should be selected to be greater than the width Y of the guide element on the lateral ribs by an overall gap dimension A1 + A2, such that the total gap dimension A1 + A2 takes into account the tolerances of the width Y of the guide element at the ends the ribs and the shrinkage and distortion occurring during operation of the handrail does not exceed 8 mm.
Bei der erfindungsgemäßen Bemessung des Handlaufs wird zunächst vomIn the inventive design of the handrail is first of
Querschnitt des Führungselements und dessen Führungssockels ausgegangen. Die Anpassung des Handlaufs an das Führungselement bedingt in der Produktion die Beherrschung und Reproduzierbarkeit aller den Querschnitt des Handlaufs beeinflussenden Schrumpf- und Verzugsvorgänge. Der betreffende Handlauf wird daher an die jeweilige Konfiguration des Führungselements und dessen Führungssockels angepasst. Die Querschnitte der Produktionswerkzeuge sowie die Halbzeuge werden derart abgestimmt, dass eine reproduzierbare Formgebung mit engen Toleranzen sichergestellt wird. Dies gilt insbesondere für Press-, insbesondere Strangpress- und Extrudierverfahren.Cross-section of the guide element and its guide base assumed. The adaptation of the handrail to the guide element requires in production the control and reproducibility of all the cross-section of the handrail influencing shrinkage and distortion processes. The handrail in question is therefore adapted to the respective configuration of the guide element and its guide base. The cross-sections of the production tools and the semi-finished products are tuned so that a reproducible shaping with tight tolerances is ensured. This applies in particular to pressing, in particular extrusion and extrusion.
Dabei sind auch die Konturen des Handlaufs sowie die Änderung der Konturen des Handlaufs im Betrieb im Rahmen von Prüfstandsversuchen und/oder - Berechnungen zu berücksichtigen; desgleichen spielen die Materialeigenschaft und die Art der Beanspruchung im Betrieb eine Rolle, was durch Vorversuche optimiert werden kann.The contours of the handrail as well as the change of the contours of the handrail during operation must also be taken into account in test stands and / or calculations; likewise the material property plays and the type of stress in operation a role, which can be optimized by preliminary tests.
Im Falle konstanter oder zunehmender Spaltmaße während des Betriebs wird der vom Handlauf umschlossene Querschnitt von der Außenkontur des Führungselements und dessen Führungssockels vorgegeben. Die obere Toleranzgrenze des Führungselements gibt die untere Toleranzgrenze der Innenkontur des Handlaufs vor. Damit wird sichergestellt, dass der Handlauf nicht auf dem Führungselement festsitzt, sondern leicht bewegt werden kann. Der Handlauf ist dann so ausgelegt, dass die Änderung des Spaltmaßes im Laufe des Betriebs, das heißt während der Lebensdauer des Handlaufs, durch das gesamte Spaltmaß C1 + C2 begrenzt ist.In the case of constant or increasing gaps during operation of the enclosed by the handrail cross section of the outer contour of the guide element and its guide base is specified. The upper tolerance limit of the guide element specifies the lower tolerance limit of the inner contour of the handrail. This ensures that the handrail is not stuck on the guide element, but can be easily moved. The handrail is then designed so that the change in the gap dimension during operation, that is, during the life of the handrail, by the total gap C1 + C2 is limited.
Falls sich das Spaltmaß während des Betriebs verringert, definiert sich die Innenkontur des Handlaufs durch die obere Toleranzgrenze des lichten Abstands C in Verbindung mit der unteren Toleranzgrenze des Führungselements und dessen Führungssockels. Das gesamte Spaltmaß C1 + C2 soll dabei einen Wert von 8 mm nicht überschreiten.If the gap decreases during operation, the inner contour of the handrail is defined by the upper tolerance limit of the clear distance C in conjunction with the lower tolerance limit of the guide element and its guide base. The total gap dimension C1 + C2 should not exceed a value of 8 mm.
Der Handlaufquerschnitt ist dabei so aufzubauen, dass über die gesamte Lebens- dauer der Handlauf nicht am Führungselement festsitzen, sondern leicht ohne übermäßig großen Kraftaufwand bewegt werden kann.The handrail cross-section should be constructed so that the handrail does not stick to the guide element over the entire service life, but can easily be moved without excessive force.
In beiden Fällen ist für ausreichende Sicherheit im Betrieb und insbesondere bei der Benutzung durch Personen Sorge getragen.In both cases, sufficient safety during operation and especially when used by persons is ensured.
Gemäß der Erfindung kann daher der Handlauf gezielt an kundenspezifische Führungselemente angepasst werden, ohne dass besonders massive Handläufe verwendet werden müssen. Eine Preisreduzierung bei der Herstellung ist daher gleichfalls ein positives Ergebnis der Erfindung.According to the invention, therefore, the handrail can be adapted specifically to customer-specific guide elements without having to use particularly massive handrails. A price reduction in the production is therefore also a positive result of the invention.
Nach einer Weiterbildung der Erfindung können die seitlichen Rippen des Führungselements unter einem Winkel α gegenüber der Ebene der Gleitfläche des Handlaufs geneigt oder hoch gebogen sein; die gebogenen Ränder des Handlaufs sind gleichfalls um etwa einen solchen Winkel nach innen in Richtung zur Gleitfläche gebogen. Hierdurch ergibt sich eine zusätzliche Abstützfunktion gegenüber einem seitlichen Abrutschen des Handlaufs vom Führungselement. Die seitlich vorstehenden Rippen des Führungselements können dann etwas kürzer als bei nicht abgewinkelter Anordnung ausgebildet sein. Das Spaltmaß B1 zwischen der Unterseite der Rippen und der nach innen eingebogenen Endteile der seitlichen Ränder sollte geringer als 6 mm sein.According to a development of the invention, the lateral ribs of the guide element can be inclined or bent at an angle α relative to the plane of the sliding surface of the handrail; the curved edges of the handrail are also bent inwardly at approximately such an angle in the direction of the sliding surface. This results in an additional support function against lateral slippage of the handrail from the guide element. The laterally projecting ribs of the guide element can then be formed slightly shorter than in the non-angled arrangement. The gap B1 between the underside of the ribs and the inwardly bent end portions of the lateral edges should be less than 6 mm.
Natürlich ist auch bei der Erfindung die Verwendung innerer Verstärkungsmittel im Handlauf möglich, um eine gewisse Quersteif ig keit sicherzustellen.Of course, in the invention, the use of internal reinforcing means in the handrail is possible to ensure a certain Quersteif ig speed.
In der Zeichnung ist ein schematischer Querschnitt einer erfindungsgemäßen Ausbildung gezeigt.In the drawing, a schematic cross section of an embodiment of the invention is shown.
Der den äußeren Konturen nach gewölbte Handlauf 1 aus elastomerem bzw. gummielastischem Material, z.B. vernetzte Elastomere, wie SBR, CSM, EPDM, CR, NR, sowie thermoplastische Elastomere, wie TPE und TPU, sitzt an seiner Unterseite in diesem Fall im wesentlichen flächig auf der Gleitfläche 2 des Führungselements 3 derart auf, dass der Handlauf 1 in Längsrichtung, das heißt senkrecht auf die Querschnittsdarstellung gleitend oder, im Falle der Verwendung von Rollen, auch rollbar entlang bewegt werden kann. Das Führungselement 3 weist seitliche, das heißt sich auch in Längsrichtung hinziehende Rippen 5 auf, die unter einem Winkel α in Richtung nach unten, das heißt zum Führungssockel 7, abgewinkelt sein können. Die Breite Y des Führungselements 3 an den äußeren Rän- dem 8 der seitlichen Rippen 5 ist etwas geringer als die lichte Weite A des Handlaufs 1 an derjenigen Stelle, an der die Ränder 4 um die Rippen 5 bis zu den Endteilen 10 herumgebogen sind. Dabei ergeben sich an den Seiten die Spaltmaße A1 und A2.The outer contour arched handrail 1 of elastomeric or rubber-elastic material, e.g. crosslinked elastomers, such as SBR, CSM, EPDM, CR, NR, and thermoplastic elastomers, such as TPE and TPU, sits on its underside in this case substantially flat on the sliding surface 2 of the guide member 3 such that the handrail 1 in the longitudinal direction, that is, sliding perpendicular to the cross-sectional view or, in the case of the use of rollers, can also be moved along rollable. The guide element 3 has lateral, that is, also in the longitudinal direction rending ribs 5, which at an angle α in the downward direction, that is to the guide base 7, can be angled. The width Y of the guide element 3 at the outer edges 8 of the lateral ribs 5 is slightly smaller than the clear width A of the handrail 1 at the point where the edges 4 are bent around the ribs 5 to the end parts 10. This results in the gaps A1 and A2 on the sides.
Die lichte Weite C der inneren Enden 6 des Handlaufs 1 ist um das gesamteThe inside width C of the inner ends 6 of the handrail 1 is around the entire
Spaltmaß C1 + C2 größer als die Breite X des Führungssockels 7. Hierdurch entstehen zwischen den inneren Enden 6 des Handlaufs 1 und dem Führungssockel 7 jeweils ein Spalt gemäß der Spaltmaße C1 und C2. Der Abstand der am weitesten nach unten gezogenen Teile der Rippen 5 von der oberen Gleitfläche 2 des Führungselements 1 ist mit Z bezeichnet, so dass sich das Spaltmaß B1 aus dem Abstand der inneren Endteile 10 des Handlaufs 1 von den um den Winkel α schräg gestellten und nach unten weisenden Seiten 9 der Rippen 5 ergibt.Gap C1 + C2 greater than the width X of the guide socket 7. This creates between the inner ends 6 of the handrail 1 and the guide base 7 each have a gap according to the gap dimensions C1 and C2. The distance of the furthest downwardly drawn parts of the ribs 5 from the upper sliding surface 2 of the guide member 1 is denoted by Z, so that the gap B1 from the distance of the inner end portions 10 of the handrail 1 of the inclined by the angle α and down facing sides 9 of the ribs 5 results.
Der Handlauf 1 weist die Gesamtbreite B auf. Diese beträgt beispielsweise 70 mm.The handrail 1 has the total width B on. This is for example 70 mm.
Der Handlauf kann insbesondere in seinem Mittelteil mit inneren Verstärkungsmitteln 11 versehen sein, um die Quersteif ig keit und Zugfestigkeit zu verbessern, ohne die Bewegbarkeit in Transportrichtung über das Führungselement 3 hinweg zu beeinträchtigen.The handrail may in particular be provided in its middle part with internal reinforcing means 11 in order to improve the transverse stiffness and tensile strength without impairing the mobility in the transport direction over the guide element 3.
