Description

The invention relates to an escalator or a moving walkway with a step belt with steps or with a pallet band with pallets for the transport of persons and / or objects and held by means of a Balustradensockels balustrade with handrail, wherein arranged on the balustrade pedestal deflector device pinching body parts and / or objects between the existing of the individual stages step band and the balustrade base prevents. The deflector device is arranged on a vertical region of the balustrade base and comprises a base profile or deflector profile and a brush unit.

Driving devices in the sense of the invention, which can also be referred to as conveyors, are escalators and moving walks with a plurality of tread units or steps or moving floor pallets, which are connected to an endless conveyor. Users of the driving devices are standing on the steps of the steps or pallets or kiting units.

In the embodiment, there is a gap between the steps (or pallets) and a vertical portion of the base plates on both sides of the traveling device. In order to prevent pinching in this gap or air gap and / or the penetration of objects, so-called base brushes are usually used.

From the patent US 6,131,719 is a safety device has become known, which prevents the pinching between the existing of individual stages step band and the base plates. Designed as a deflector safety device consists of a large support profile and different brush elements. The arranged on Balustradensockel large carrier profile has a profiled opening on the stage side, in which opening the brush elements can be inserted. A brush element consists of a brush body that holds the brushes. The brush body is inserted at the front (from the step side) into the profiled opening of the large, robust carrier profile. After mounting the brush element, a wedge element is inserted from a carrier profile end forth between the upper wall of the large support profile and the brush body, wherein the wedge element holds the brush body with a rib.

Further driving devices with corresponding base brushes are from the writings EP 1 170 244 . EP 1 262 441 . EP 1 188 708 and DE 199 17 796 known, for example.

The following is from EP 1 262 441 assumed as the closest prior art. In this document a deflector device is described which is arranged on the or a vertical region of the balustrade base and comprises a deflector profile and a brush unit. During assembly, the brush unit is inserted laterally into the massive, robust, large-area deflector profile.

A disadvantage of said safety devices is that the assembly is complicated and time-consuming. Other solutions, in turn, are characterized by being easier to assemble. Here, however, is disadvantageous that the simplicity of the installation was bought by a not so robust and stable seat of the safety device.

From the Scriptures US 6,425,472 a deflection device arranged on the balustrade pedestal of an escalator has become known which consists of a brush carrier with deflector brushes and of a deflector pedestal arranged on the balustrade pedestal. The upper edge of the brush holder and the upper edge the Abweisersockels are formed so that the two edges together form a hinge, wherein the edge of the brush holder is hook-shaped in cross-section and the edge of the Abweisersockels in cross-section pear shape and the hook can slide on the bulb. To mount the deflector the Abweisersockel is fastened to the balustrade base and then the brush holder is inserted at the upper edge of the Abweisersockel and folded with a rotational movement about the hinge axis down.

Here is the invention to remedy the situation. The invention, as characterized in claim 1 solves the problem of avoiding the disadvantages of the prior art devices and to provide a safety device that is easily and quickly attachable to the base of the escalator and still guarantees outstanding stability and strength.

An escalator according to the invention or a moving walkway according to the invention comprises a step belt with steps or a pallet conveyor with pallets and a balustrade with handrail held by means of a balustrade pedestal. A deflector device is disposed on the balustrade pedestal to prevent trapping between the steps and the balustrade pedestal. The deflector device has a deflector profile and a brush unit arranged on the or a vertical region of the balustrade pedestal. The deflector profile comprises means for easy or quick vertical joining or joining of the brush unit with the deflector profile.

The advantages achieved by the invention are essentially to be seen in the fact that a little complicated assembly of the brush units is possible, while still a high strength or stability or robustness is achieved. If replacement of the brush units is necessary, the old brush units are removed or exchanged with simple means or tools and the new brush units can be mounted without tools on the existing deflector profile by snapping or snapping. With the inventive latching device or latching device, which is assembled by vertical joining or fastening, an endless deflector can be realized, which is independent of predetermined by the stepping or pallet run direction changes.

Preferred developments of the inventive deflecting device and the driving device are defined by the dependent claims.
