Problems solved by technology

A disadvantage of such base plates according to the prior art is that they protrude relatively far upwards beyond the tread walking surface in the horizontal section of the escalator (ie the entry point and the exit point), or that they have a relatively complex configuration

Embodiment Construction

[0022] FIG. 1 shows an escalator 2 with an endless step belt 6 consisting of a number of interconnected treads 4 . The pedals 4 are each connected to a conveyor chain 8 arranged laterally thereto. The term "laterally" attached to the pedal 4 includes an embodiment in which the pedal chain 8 is arranged laterally adjacent to the pedal 4 if seen from a top view, and also includes an embodiment in which the pedal chain 8 is arranged laterally below the walking surface 16 of the pedal 4 if seen from a top view. Example. The conveyor chain 8 consists of a series of links 10 . The chain links 10 are connected to each other at a pivot 12 . Also arranged on these pivots 12 are pedal chain rollers 14 which guide the pedal chain 8 along a closed continuous path in a pedal chain guide rail (not shown).

[0023] The escalator 2 is driven by a linear drive (not shown) obtained by means of an endless revolving toothed belt. The teeth of the toothed belt mesh with the teeth 16 of the cha...

Abstract

The invention pertains to an escalator (2) with an endless stair band (6) that is composed of several interconnected steps (4), wherein a step (4) contains a walking surface (16) and a front side (18) and is connected to respective lateral step chains (8) that are driven around a lower and an upper reversing point (22) by means of a drive, and wherein a step (4) contains at least one step roller (34) that is guided by a step roller guide. The invention is characterized by the fact that the point (32) at which a step (4) is fastened to the step chain (8) is arranged in the vicinity of the front side (18) of the step (4).

Description

technical field [0001] The present invention relates to an escalator with an endless step band consisting of a number of interconnected treads, where the treads comprise a walking surface and a front side and are connected to respective chains of side treads which run around by means of drive means The lower and upper steering positions are driven, and here the pedals contain at least pedal rollers guided by a pedal roller guide. Background technique [0002] Many escalators of this type are in use. The steering position is generally achieved with a chain deflecting wheel or a pair of chain deflecting wheels, around which the two laterally arranged pedal chains of the stepped belt are guided and driven. There are also escalators in which the advancement of the tread chain does not take place near the turning position, but eg in the front or rear travel section. In this type of escalator, instead of its chain deflecting rollers, for example deflecting plates or substantiall...
