Escalator or moving walkway

Abstract

The present invention relates to an escalator or moving walkway having a circulating escalator step belt or panel belt, each escalator step or panel having, on each side, a respective supporting roller and a chain roller, which are guided on supporting-roller rails and chain-roller rails in the forward strand and in the return strand. The supporting-roller return rails (26) support only part of the supporting roller (14).

Description

technical field

[0001] The present invention relates to an escalator or moving walk. Background technique

[0002] The support of the escalator steps and the floor of the moving walk is usually achieved by means of sprockets and support wheels, which run on respective associated rails. The steps or base plates must be conveyed upside down during the return trip and a deflection must be performed at the end of the moving walk or escalator. This results in a regular lateral offset of the rollers and thus the respective associated rails relative to one another. The sprocket and the sprocket track thus usually extend considerably further outwards in one side plane, while the support wheels run on the other side plane, usually offset inwards. On the other hand, this lateral offset also results in an increased lateral structural width of the escalator or moving walk.

[0003] In order to avoid this, it has long been known that the rollers and the associated rails can extend at ...

Embodiment Construction

[0017] The escalator 10 according to the invention has escalator steps, in figure 1 One of the escalator steps 12 is shown in . Each step has a support wheel 14 and a sprocket 16 on each side, which are each mounted on a journal. The journal 18 of the sprocket 16 can be obtained from figure 1 As can be seen in FIG. 1 , the relevant journal of the bearing wheel 14 is covered by the view of the step 12 and is represented only by the schematically indicated axis 20 of the bearing wheel 14 .

[0018] The sprocket 16 is supported via a sprocket rail 22 in a known manner. The sprocket track 22 extends laterally far enough outside and has a desired width and is significantly wider than the sprocket 16 . sprocket 16 in accordance with figure 1 The case is supported on the inner half of the rail 22 , that is, the half facing the step 12 .

[0019] Support wheel 14, in accordance with figure 1 In a suspended view of the escalator step 12 protrudes slightly, for example by about on...
