Abstract

The invention relates to a step ( 4 ) of an escalator or a plate ( 14 ) of a moving walkway. This comprises a tread element ( 40 ) and a support body ( 30 ) with a base ( 31 ), wherein the tread element ( 40 ) comprises at least two sub-elements ( 41, 42, 43 ) and each sub-element ( 41, 42, 43 ) is bounded in the areal extent thereof by two parallel end sides ( 45, 46 ) extending in the intended direction (X) of movement of the step ( 4, 304 ) or plate ( 14, 114 ) and two edge sides ( 47, 48, 147, 148 ) arranged orthogonally to the end sides ( 45, 46 ). The at least two sub-elements ( 41, 42, 43 ) are arranged in a predetermined sequence on the base ( 31 ) of the support body ( 30 ). Sub-elements ( 41, 42, 43 ) arranged adjacent to one another respectively bear against one another by one of the end sides ( 45, 46 ) thereof, wherein a sub-element ( 41, 42 ) previously arranged on the base ( 31 ) is secured to the support body ( 30 ) by the respective sub-element ( 42, 43 ) subsequently arranged on the base ( 31 ).

First claim

The invention claimed is:

1. A step/plate for an escalator or moving walkway, comprising a tread element and a support body with a base, wherein the tread element comprises at least two sub-elements, each sub-element being bounded in the areal extent thereof by two parallel end sides extending in an intended direction (X) of movement of the step/plate and two edge sides arranged orthogonally to the end sides, wherein the at least two sub-elements are arranged in a predetermined sequence on the base of the support body and wherein adjacently arranged sub-elements respectively bear against one another through contact between end sides thereof; a first sub-element on the base being secured to the support body by a second respective sub-element successively arranged on the base, wherein each sub-element has at least one projection in a region of at least one end side, the projections of adjacent end sides of two sub-elements bearing against one another are so arranged such that the at least one projection of the first sub-element previously placed on the base hooks under a subsequently placed second sub-element, and the at least one projection of the second sub-element subsequently placed on the base hooks under the base of the support body.

2. The step/plate according to claim 1 , wherein the base has at least one positioning passage and each sub-element has at least one protruding positioning element formed to precisely fit into one of the at least one positioning elements when the sub-element is positioned on the base.

3. The step/plate according to claim 1 , wherein a previously placed sub-element is biased by the successively placed sub-element against the base.

4. The step/plate according to claim 1 , wherein a resilient intermediate layer is arranged between the support body and the tread element.

5. The step/plate according to claim 1 , wherein one of the sub-elements is a start element, a first end side of which has a lateral edge section parallel to the one end side and a fastening region, a second end side of which having at least one projection.

6. The step/plate according to claim 5 , wherein at least one fastening projection is formed at the fastening region for hooking under the base of the support body.

7. The step/plate according to claim 1 , wherein one of the sub-elements is a middle element which has at least one left hand projection at a left hand end side and at least one right hand projection at a right hand end side.

8. The step/plate according to claim 1 , wherein one of the sub-elements is an end element, a left hand end side of which has at least one left hand projection and a right hand end side of which has a lateral edge section which is parallel to the right hand end side and has a fastening region.

9. The step/plate according to claim 8 , wherein when the end element is placed on the base the fastening region is fixedly connected with the base by at least one fastening element.

10. The step/plate according to claim 1 , wherein the base of the support body has at least one mounting passage and, when the sub-elements are sequentially placed on the base bearing against one another, in the region of the end sides bearing against one another a projection of a previously placed sub-element and a projection of a successively placed sub-element are arranged adjacent to one another and extend in the mounting passage.

11. The step/plate according to claim 1 , wherein the support body is of tubular construction and has a cross section chosen from the group consisting of triangular and trapezium shapes.

12. A plate belt of a moving walkway with at least one traction means and with a plurality of step/plates according to claim 1 arranged at the traction means.

13. A step belt of an escalator with at least one traction means and with a plurality of step/plates according to claim 1 arranged at the traction means.

14. A moving walkway with a step/plate belt according to claim 13 arranged to circulate.

15. An escalator with a step/plate belt according to claim 14 arranged to circulate.
