Abstract
Official abstract text for this publication.
A passenger conveyor includes a first stationary structure and a second stationary structure; a step positioned between the first stationary structure and the second stationary structure, the step has a tread with a tread surface; and a skirt secured to the step between the step and the first stationary structure, the skirt includes an upper tread edge; wherein the upper tread edge extends beyond the tread surface by at least about 10 mm.
First claim
Opening claim text (preview).
The invention claimed is: 1. A passenger conveyor comprising: a first stationary structure and a second stationary structure; a step positioned between the first stationary structure and the second stationary structure, the step having a tread with a tread surface; and a skirt secured to the step between the step and the first stationary structure, the skirt including an upper tread edge; wherein the upper tread edge extends beyond the tread surface by at least about 10 mm. 2. The passenger conveyor of claim 1 wherein: the upper tread edge extends beyond the tread surface by about 10 mm to about 30 mm. 3. The passenger conveyor of claim 2 wherein: the upper tread edge extends beyond the tread surface by about 15 mm. 4. The passenger conveyor of claim 1 wherein: the step includes a riser with a riser surface. 5. The passenger conveyor of claim 4 wherein: the skirt includes a front riser edge, the front riser edge extends beyond the riser surface by at least about 10 mm. 6. The passenger conveyor of claim 5 wherein: the front riser edge extends beyond the riser surface by about 10 mm to about 30 mm. 7. The passenger conveyor of claim 6 wherein: the front riser edge extends beyond the riser surface by about 25 mm. 8. The passenger conveyor of claim 5 wherein: upper tread edge extends beyond the tread surface by a first distance and the front riser edge extends beyond the riser surface by a second distance, the first distance and the second distance being unequal. 9. The passenger conveyor of claim 1 wherein: the skirt is integrally formed with the step. 10. The passenger conveyor of claim 1 wherein: the skirt is fastened to the step. 11. A passenger conveyor step comprising: a tread with a tread surface; and a skirt secured to the step, the skirt including an upper tread edge; wherein the upper tread edge extends beyond the tread surface by at least about 10 mm. 12. The passenger conveyor step of claim 11 wherein: the upper tread edge extends beyond the tread surface by about 10 mm to about 30 mm. 13. The passenger conveyor step of claim 12 wherein: the upper tread edge extends beyond the tread surface by about 15 mm. 14. The passenger conveyor step of claim 11 wherein: the step includes a riser with a riser surface. 15. The passenger conveyor step of claim 14 wherein: the skirt includes a front riser edge, the front riser edge extends beyond the riser surface by at least about 10 mm. 16. The passenger conveyor step of claim 15 wherein: the front riser edge extends beyond the riser surface by about 10 mm to about 30 mm. 17. The passenger conveyor step of claim 16 wherein: the front riser edge extends beyond the riser surface by about 25 mm. 18. The passenger conveyor of claim 15 wherein: the upper tread edge extends beyond the tread surface by a first distance and the front riser edge extends beyond the riser surface by a second distance, the first distance and the second distance being unequal. 19. The passenger conveyor step of claim 11 wherein: the skirt is integrally formed with the step. 20. The passenger conveyor step of claim 11 wherein: the skirt is fastened to the step. 21. A passenger conveyor comprising: a first stationary structure and a second stationary structure; a step positioned between the first stationary structure and the second stationary structure, the step having a tread with a tread surface and a riser with a riser surface; and a skirt secured to the step between the step and the first stationary structure, the skirt including a front riser edge; wherein the front riser edge extends beyond the riser surface by at least about 10 mm. 22. A passenger conveyor step comprising: a tread with a tread surface and a riser with a riser surface; and a skirt secured to the step, the skirt including a front riser edge; wherein the front riser edge extends beyond the riser surface by at least about 10 mm.
