Description
Die derzeit auf dem Weltmarkt erhältlichen Handläufe entsprechen nicht oder nur zum Teil den heutigen Anforderungen der Fahrtreppenhersteller.The handrails currently available on the world market do not meet, or only partially meet, the current requirements of escalator manufacturers.
Die aus vielen Einzelkomponenten (SBR, EPDM, Polyamid, Polyester, Baumwolle, Glasfaserkord, Stahl usw.) konfektionierten Handläufe zeigen immer wieder die Grenzen heutiger Kautschukverbundprodukte auf. Ausfallbilder wie Karkassenablösungen, Blasen, aufgeplatzte Trennebenen, Lippen - und Ozonrisse usw. sind bei allen Wettbewerbern an der Tagesordnung.The handrails, which are made from many individual components (SBR, EPDM, polyamide, polyester, cotton, glass fiber cord, steel, etc.), repeatedly demonstrate the limits of today's rubber composite products. Failure patterns such as carcass detachments, blisters, bursted parting lines, lip and ozone cracks, etc. are commonplace for all competitors.
Der Preisdruck und viele neue Umweltverordnungen zwingen die Handlaufhersteller dazu, immer wieder neue Ersatzstoffe einzusetzen, welche die Haltbarkeit ihres Produktes auf ein Bruchteil der ursprünglichen Standzeit sinken lassen.Price pressure and many new environmental regulations force handrail manufacturers to continually use new substitute materials, which reduce the durability of their product to a fraction of the original service life.
Die einvulkanisierten Stahlzugträger oxidieren nach kürzester Zeit und verkürzen sich, was zu erhöhtem Abrieb von Handlauf und Bailustrade bzw. zur Zerstörung der Handläufe führt.The vulcanized steel tension members oxidize after a very short time and shorten, which leads to increased abrasion of the handrail and balustrade or to the destruction of the handrails.
Endlosverbindungen verlangen vom Vulkaniseur höchstes handwerkliches Geschick und sind sehr zeitaufwendig.Endless connections require the vulcanizer to have the highest level of craftsmanship and are very time-consuming.
Die garantierte Zugfestigkeit der Handläufe wird durch stetige Biegewechselbeanspruchung der Stahlseile, Oxidation und zweifelhafte Verbindungstechnologien in den wenigsten Fällen dauerhaft eingehalten.The guaranteed tensile strength of the handrails is rarely maintained permanently due to constant alternating bending stresses on the steel cables, oxidation and dubious connection technologies.
Aber auch viele andere -in heutiger Zeit "normale"- Anforderungen der Fahrtreppenindustrie werden von den Handlaufproduzenten als irreal bzw. nicht machbar bezeichnet. Farbige Handläufe zum Preis von schwarzen, niedrigere Reibkoeffizienten zwischen Handlauf und Führung, schlupf loser Antrieb, flammfeste Qualitäten, Recyclebarkeit usw. stehen außer jeder Diskussion.But many other requirements of the escalator industry - which are "normal" today - are described by the handrail manufacturers as unrealistic or not feasible. Colored handrails for the price of black ones, lower friction coefficients between the handrail and the guide, slip-free drive, flame-resistant qualities, recyclability, etc. are beyond any discussion.
Gegenstand der Erfindung und des Schutzanspruches ist / sind : The subject matter of the invention and the claim is/are :
1. ein Handlauf für Fahrtreppen und Fahrsteige, der aus einem thermoplastischen Elastomer ( TPE, TPO, TPU ),vorzugsweise einem thermoplastischem Polyurethan-Elastomer gefertigt (extrudiert) wird.1. a handrail for escalators and moving walkways, which is made (extruded) from a thermoplastic elastomer (TPE, TPO, TPU), preferably a thermoplastic polyurethane elastomer.
2. ein Zugträger, der sich in der Mitte des Handlaufes belindet, augeführt als Rollenkette mit seitlichem Bolzenüberstand, der formschlüssig von unten in eine dafür vorgesehene Aussparung eingeklippt wird.2. a tension member located in the middle of the handrail, designed as a roller chain with a lateral bolt projection, which is clipped into a recess provided for this purpose from below.
3. im extrudierten Profil vorgesehene Hohlkanäle, die sowohl helfen, Material ( Gewicht) zu sparen, als die Biegesteifigkeit zu reduzieren.3. Hollow channels provided in the extruded profile, which help to save material (weight) and reduce the bending stiffness.
4. an der Unterseite des Handlaufes rechts und links neben der Zugträgeraussparung befindliche Kanäle, in denen die Ballustradenführung der Fahrtreppe läuft.4. Channels located on the underside of the handrail to the right and left of the tension member recess, in which the balustrade guide of the escalator runs.
(Jürgen Bluhm / 23.02.1999)(Jürgen Bluhm / 23.02.1999)
5. ein dünnwandiger Schlauch aus ultra-hochmolekularem Polyethylen (alternativ Polytetrafluorethylen),der in die unter Punkt 4 genannten Kanäle eingebracht und beim Aufknüpfen auf die Ballustradenfühning zusammengedrückt wird. Das sich nun an der Oberseite des Führungskanals befindliche dublierte PE-HD-UHMW bzw. PTFE Material minimiert den Reibungskoeffizienten zwischen Führung und Handlauf und reduziert den Abrieb auf ein Minimum.5. a thin-walled tube made of ultra-high molecular weight polyethylene (alternatively polytetrafluoroethylene), which is inserted into the channels mentioned under point 4 and is compressed when tied onto the balustrade guide. The doubled PE-HD-UHMW or PTFE material now on the top of the guide channel minimizes the coefficient of friction between the guide and the handrail and reduces abrasion to a minimum.
