Abstract

A truss section ( 2, 3, 4 ), which is configured to support at least one tread element in a passenger area ( 30 ) of a passenger conveyor ( 15 ) of the type conveying passengers by moving the at least one tread element in a longitudinal direction along the passenger area ( 30 ) between a first landing and a second landing, comprises at least two longitudinal elements ( 5 a, 5 b ) extending basically parallel to each other in the longitudinal direction; and at least one lateral connector ( 6 ) connecting the at least two longitudinal elements ( 5 a, 5 b ). Each of the at least two longitudinal elements ( 5 a, 5 b ) includes at least one load-bearing portion ( 51, 52, 53 ) having the configuration of a single wall profile.

First claim

The invention claimed is:

1. A truss section configured to support at least one tread element in a passenger area of a passenger conveyor of the type conveying passengers by moving the at least one tread element in a longitudinal direction along the passenger area between a first landing and a second landing;
the truss section comprising:
at least two longitudinal elements extending basically parallel to each other in the longitudinal direction;
at least one lateral connector connecting the at least two longitudinal elements, wherein each of the at least two longitudinal elements comprises at least one load-bearing portion having the configuration of a single wall profile; and
an inner skirt panel which is formed integrally with the at least one load-bearing portion.

2. The truss section according to claim 1 , wherein the load-bearing portion has a substantially vertically extending body portion and a substantially horizontally extending foot portion, a lower part of the body portion being connected to the foot portion, any of the body portion and/or the foot portion having the configuration of a single wall profile.

3. The truss section according to claim 2 , wherein the body portion faces towards the passenger area.

4. The truss section according to claim 2 , wherein the foot portion extends from the body portion towards a side facing the passenger area as well as towards an opposite side facing away from the passenger area.

5. The truss section according to claim 1 , wherein the at least one longitudinal element comprises receiving means and/or fixing means for mounting balustrade elements and/or the at least on outer cover element to the truss section.

6. The truss section according to claim 5 , comprising magnets for fixing the balustrade elements and/or the at least one cover element, and/or comprising slots formed in the at least one longitudinal element, the slots being configured for fixing balustrade elements and/or the at least one cover element by means of clipping.

7. The truss section according to claim 1 , wherein the load-bearing portion has a genus of zero.

8. The truss section according to claim 1 , comprising at least one roller track configured to support the at least one tread element while moving in the passenger line and/or while moving in a return line of the passenger conveyor, respectively, the at least one roller track being formed integrally with the load-bearing portion.

9. The truss section according to claim 1 , wherein the at least one load-bearing portion is formed by a profiled bar made of lightweight material, in particular aluminium.

10. The truss section according to claim 9 , wherein the at least one load-bearing portion is an extruded or roller molded element.

11. The truss section according to claim 1 , wherein the at least one lateral connector comprises at least two lateral elements extending basically parallel to each other.

12. The truss section according to claim 11 , wherein the at least two lateral elements are arranged in different vertical positions.

13. Truss module configured to be connected with a plurality of other truss modules arranged adjacent to each other in the longitudinal direction such as form a truss; the truss module comprising a truss section according to claim 1 .

14. Passenger conveyor of the type conveying passengers by moving at least one tread element in a longitudinal direction along a passenger area between a first landing and a second landing, the passenger conveyor comprising a truss made up with a plurality of truss modules arranged adjacent to each other in the longitudinal direction, each of the truss modules comprising at least two longitudinal elements extending basically parallel to each other in the longitudinal direction; and a least one lateral connector connecting between the at least two longitudinal elements, at least one of the truss modules having a configuration according to claim 13 .

15. Passenger conveyor of claim 14 , wherein the passenger conveyor is a moving walkway configured for transporting passengers basically horizontally and/or parallel to a basement of the passenger area.

16. A truss section configured to support at least one tread element in a passenger area of a passenger conveyor of the type conveying passengers by moving the at least one tread element in a longitudinal direction along the passenger area between a first landing and a second landing;
the truss section comprising:
at least two longitudinal elements extending basically parallel to each other in the longitudinal direction;
at least one lateral connector connecting the at least two longitudinal elements, wherein each of the at least two longitudinal elements comprises at least one load-bearing portion having the configuration of a single wall profile; and
at least one outer cover element attached to a load-bearing portion on a side facing away from the passenger area such that the load-bearing portion and the cover element define a compartment for the handrail return section of the passenger conveyor.

17. The truss section according to claim 16 , wherein the cover element is removable attached, in particularly clipped, to the load-bearing portion.
