Aus der Anmeldeschrift EP 04004311.9 ist ein Aufzug mit einer 2:1 Seilführung bekannt geworden, bei dem die Umlenkrollen der Aufzugskabine im Kabinenboden bzw. im Gegengewicht integriert sind. Das Trag- und Treibmittel wird im Kabinenboden durch einen Bodenkanal geführt. Gegenüber einem herkömmlichen Kabinenboden mit unterhalb angeordneten Umlenkrollen (Unterflaschen) baut der Kabinenboden gesamthaft in der Höhe sehr gering, was sich direkt auf die Schachtgrubentiefe auswirkt. Die mit dem Kabinenboden gewonnene Höhe kann in der Schachtgrubentiefe eingespart werden.From the registration EP 04004311.9 an elevator with a 2: 1 cable guide has become known in which the pulleys of the elevator car are integrated in the cabin floor or in the counterweight. The carrying and blowing agent is guided in the cabin floor through a floor duct. Compared to a conventional cabin floor with pulleys arranged underneath (bottom bottles), the cabin floor as a whole builds very low in height, which has a direct effect on the shaft pit depth. The height gained with the cabin floor can be saved in the shaft pit depth.

Ein Nachteil der bekannten Einrichtung liegt darin, dass die in der Aufzugskabine bzw. im Gegengewicht integrierten Umlenkrollen zusammen mit dem einlaufenden Trag- und Treibmittel für das Unterhaltspersonal eine erhebliche Gefahr darstellen.A disadvantage of the known device is that the integrated in the elevator car or counterweight pulleys together with the incoming support and propellant for the maintenance personnel represent a significant risk.

Aus der JP 02295878 ist eine an einem Träger einer Aufzugskabine oder eines Gegengewichtes angeordnete Umlenkrolle bekannt geworden. Das an der Umlenkrolle 180° umgelenkte Tragseil trägt die Aufzugskabine bzw. das Gegengewicht, wobei eine 2:1 Seilführung vorgesehen ist. Der Seilumlenkbereich an der Umlenkrolle ist mit einer Abdeckung versehen.From the JP 02295878 is a arranged on a support of an elevator car or a counterweight deflection pulley has become known.

Die Enden der Seitenschilder 23.4 sind mit Nasen versehen, die in Ausnehmungen des Trägers 20.2 eintauchen. Die Abdeckungen 23 werden werkzeuglos montiert und mit dem Bügel 25 gesichert. Fig. 6 shows provided with hood-shaped covers 23 pulleys 20 of the counterweight 4, wherein the pulleys 20 are arranged on a yoke 4.1 of the counterweight 4. As carrying and blowing means double guided belt 11 are provided, which are guided over the pulleys 20. The roller axle 20.1 and a bracket 25 are supported by a carrier 20.2 arranged on the yoke 4.1. Each roller 20, a cover 23 is provided, the circular arc of the side plates 23.4 include the roller axis 20.1 by more than 180 °. The ends of the side plates 23.4 are provided with lugs which dip into recesses of the carrier 20.2. The covers 23 are mounted without tools and secured with the bracket 25.

Die Abdeckung 23 dient auch als Entgleisungsschutz. Ein um eine halbe Längsrippenteilung versetzter Riemen 11 streift an den Seitenschildern 23.4 und wird von diesen wieder in seine Ursprungslage gezwungen. Ein schlaff werdender Riemen 11 kann mit der erfindungsgemässen Abdeckung 23 die Rollenrillen 16.5 nicht verlassen.The cover 23 also serves as derailment protection. A staggered by a half longitudinal rib pitch belt 11 touches the side plates 23.4 and is forced by them back to its original position. A slacking belt 11 can not leave the roller grooves 16.5 with the cover 23 according to the invention.

Die bei der Montage in mechanische Spannung versetzte Abdeckung 23 kann keine Klappergeräusche erzeugen. Die Abdeckung 23 ist einfach auf der Rollenachse 16.1 zentrierbar. An der Rollenachse 16.1,20.1 können auch Nuten vorgesehen sein, in die die Seitenschilder 23 am Kreisbogen 23.31 passen.The offset during assembly in mechanical tension cover 23 can not generate rattling noises. The cover 23 is easily centered on the roller axle 16.1. On the roller axle 16.1,20.1 and grooves can be provided, in which the side plates 23 fit on the arc 23.31.
