Abstract

A step of an escalator or a pallet of a moving walk has a supporting body with a base and at least one tread-element with a tread-surface wherein, on an underside that faces away from the tread-surface, the at-least one tread-element has at least one fastening protrusion. In the assembled state, the at-least one fastening protrusion protrudes through an opening in the base. Arranged on the side of the base that faces away from the tread-element, at least partly between the base and the fastening protrusion, is at least one fixing element. The fixing element fixes the tread-element against the base in a pretensioned manner.

First claim

1 - 14 . (canceled)

15 . A step of an escalator or a pallet of a moving walk comprising:
a supporting body with a base; a fixing element; and a tread-element with a tread-surface, wherein the tread-element has a fastening protrusion on an underside facing away from the tread-surface and protruding through an opening in the base, the fastening protrusion having a slot that extends parallel to the tread-surface and into which slot the fixing element is at least partly inserted, wherein the fixing element is arranged at least partly between the base and the tread-element and the tread-element is fixed by the fixing element against the base with a pretension force.

16 . The step or the pallet according to claim 15 wherein the fastening protrusion extends perpendicular to the tread-surface.

17 . The step or the pallet according to claim 15 wherein the tread-element extends in a plane bounded by two parallel end-faces that extend in an intended direction of movement of the step or the pallet in use and by two side-edges arranged perpendicular to the end-faces.

18 . The step or the pallet according to claim 15 wherein the fixing element is displaceable parallel to the base.

19 . The step or the pallet according to claim 15 including another tread-element having another fastening protrusion protruding through another opening in the base and fixed by the fixing element against the base with another pretension force.

20 . The step or the pallet according to claim 15 wherein the fixing-element has a wedge-tongue for generating the pretension force.

21 . The step or the pallet according to claim 20 wherein the wedge-tongue is elastic.

22 . The step or the pallet according to claim 15 wherein the fixing element includes a catch engaging the base or the fastening protrusion.

23 . The step or the pallet according to claim 15 wherein the tread-element includes a positioning lug that protrudes into a positioning opening of the base.

24 . The step or the pallet according to claim 15 wherein the supporting body is tubular in cross-section.

25 . The step or the pallet according to claim 24 wherein the supporting body is triangular cross-section.

26 . A pallet-band of a moving walk comprising at least one traction means and with a plurality of the pallet according to claim 15 arranged on the at least one traction means.

27 . A moving walk with the pallet-band according to claim 26 arranged to circulate.

28 . A step-band of an escalator comprising at least one traction means and with a plurality of the step according to claim 15 arranged on the at least one traction means.

29 . An escalator with the step-band according to claim 28 arranged to circulate.

30 . A method for modernization of a moving walk comprising the steps of:
providing a new pallet-band having at least one traction means and with a plurality of pallets arranged thereon, each of the pallets including a supporting body with a base, a fixing element, and a tread-element with a tread-surface, wherein the tread-element has a fastening protrusion on an underside facing away from the tread-surface and protruding through an opening in the base, the fastening protrusion having a slot that extends parallel to the tread-surface and into which slot the fixing element is at least partly inserted, wherein the fixing element is arranged at least partly between the base and the tread-element and the tread-element is fixed by the fixing element against the base with a pretension force; and replacing an existing pallet-band of the moving walk with the new pallet-band.

31 . A method for modernization of an escalator comprising the steps of:
providing a new step-band having at least one traction means and with a plurality of steps arranged thereon, each of the steps including a supporting body with a base, a fixing element, and a tread-element with a tread-surface, wherein the tread-element has a fastening protrusion on an underside facing away from the tread-surface and protruding through an opening in the base, the fastening protrusion having a slot that extends parallel to the tread-surface and into which slot the fixing element is at least partly inserted, wherein the fixing element is arranged at least partly between the base and the tread-element and the tread-element is fixed by the fixing element against the base with a pretension force; and replacing an existing step-band of the escalator with the new step-band.
