Problems solved by technology

However there is also a certain risk that the bridge elements will come off due to sabotage
In this case there is a "hole" with running side guards around it which is very dangerous

Embodiment Construction

[0021] FIG. 1 shows a passenger conveyor in the form of an escalator 2 , which has an endless stepped belt 6 made up of a plurality of interconnected tread steps 4 . The step ladders 4 are respectively connected with the side conveyor chains 8 . The "sideways" connection to the step ladder 4 includes not only embodiments in which the conveyor belt or the step chain 8 is arranged laterally next to the step step 4 in plan view, but also embodiments in which the step chain 8 In plan view, it is arranged laterally below the tread surface 16 of a tread ladder. The conveyor chain 8 consists of a number of chain links 10 . Chain link 10 and pivot point 12 are connected to each other. Step chain rollers 14 are also arranged at these pivot points 12 , which guide the step chain 8 along a closed circumferential path into a guide (not shown) for the step chain.

[0022] The step chain 2 is driven by a (not shown) linear drive which is designed in the form of a linear drive formed by a...

Abstract

A people conveyor (2) comprising an endless tread belt (6) which is formed by several interconnected tread elements (4) and which is driven by a first drive about a first and second return element (22), and a side casing (24) which is displaced along with the tread belt (6), said casing (24) comprising flange elements (28) connected to the tread elements (4) and connected bridge elements (30) which can move in relation to the flange elements (28). The invention is characterized by a sensor (38) which is arranged in an adjacent position to the moving side casing (24). The sensor has a detection range which is defined at a right angle to the circulatory direction of movement of the side casing (24). Marking elements () are arranged on the side casing (24) in a line along the circulatory direction of movement, having a defined width at a right angle to the circulatory direction of movement.

Description

technical field [0001] The invention relates to a passenger conveyor having an endless stepped belt consisting of a plurality of interconnected tread elements which is driven by a drive around a first and a second reversing device , and has a side fence running together with the stepped belt, wherein the side fence has a flange element connected to the pedal element and a bridge element connected to the flange element for relative movement. Background technique [0002] Passenger conveyors of this type are known, for example, from DE 101 56 991 A1 and DE 101 56 992 A1. Escalators and moving conveyors are typical examples of passenger conveyors having a surrounding, endless tread belt. An escalator therefore typically has a number of connected step bodies, which together form a tread belt. The pedal bodies are driven by a drive motor around an upper reversing device and a lower reversing device—for example in the form of a reversing sprocket, a reversing guide rail, or a re...
