Abstract

The disclosure relates to a passenger transport system in the form of an escalator or a moving walkway. The system can include a stationary access region, a transport belt made up of a plurality of tread units, a transition region in which combing structures of the transport belt adjoin static comb structures of the access region, and an illuminating device having at least one light source for emitting light in the visible spectrum. The illuminating device can be configured such that at least a first portion of the light emitted is focused to predominantly illuminate an elongate transition surface which includes the transition region.

First claim

The invention claimed is:

1. A passenger transport system configured as an escalator or a moving walkway, the passenger transport system comprising:
a stationary access region;
a transport belt comprising a plurality of tread units arranged along a direction of motion, the transport belt configured to be displaced in a circumferential manner relative to the stationary access region;
a transition region in which combing structures of the transport belt adjoin static comb structures of the access region;
an illuminating device having at least one light source for emitting light in the visible spectrum,
wherein the illuminating device is configured such that at least a first portion of the light emitted by the at least one light source is focused such that it predominantly illuminates an elongate transition surface which includes the transition region including the comb structures and the combing structures of the transport belt which mesh therewith in the region of the comb structures,
wherein the transition surface extends transversely to a direction of longitudinal extension of the passenger transport system along an entire exposed width of the transport belt, and
wherein the illuminating device further comprises a projection device, the projection configured to project a second portion of the light emitted by the at least one light source onto a projection surface such that at least one symbol selected from a plurality of possible symbols is selectively displayed.

2. The passenger transport system of claim 1 , wherein the illuminating device is configured such that the first portion of the light emitted by the at least one light source illuminates at least 80% of the elongate transition surface by.

3. The passenger transport system of claim 1 , wherein the elongate transition surface is substantially rectangular.

4. The passenger transport system of claim 1 , wherein the elongate transition surface has a length dimension which extends along the entire exposed width of the transport belt and a width dimension which extends perpendicularly to the length dimension, wherein the width dimension is less than 20% of the length dimension.

5. The passenger transport system of claim 4 , wherein the width dimension is less than 20 cm.

6. The passenger transport system of claim 1 , wherein the illuminating device is configured such that the first portion of the light emitted by the at least one light source illuminates the elongate transition surface with a homogeneity of more than 50%.

7. The passenger transport system of claim 1 , wherein the illuminating device is configured to emit light selectively with different light spectra.

8. The passenger transport system of claim 1 , wherein the at least one light source is a light-emitting diode.

9. The passenger transport system of claim 1 , wherein the illuminating device is arranged on a balustrade to the side next to the transition region.

10. The passenger transport system of claim 1 , wherein the projection surface is a partial region on a balustrade.

11. The passenger transport system of claim 1 , wherein the projection surface is a partial region on the transport belt.

12. The passenger transport system of claim 1 , wherein the projection surface is a partial region on the stationary access region.

13. The passenger transport system of claim 1 , wherein the projection device comprises a plurality of masks which are configured to be selectively arranged between the at least one light source and the projection surface, wherein each of the masks is configured to project light passing through as one or more symbols selected from the plurality of possible symbols onto the projection surface.

14. The passenger transport system of claim 1 , wherein the projection device comprises a variable mask which is arranged between the at least one light source and the projection surface, wherein the variable mask is configured to variably project light passing through as one or more symbols selected from the plurality of possible symbols onto the projection surface.

15. The passenger transport system of claim 1 , wherein the projection device has a displacement mechanism which is configured to displace the projection surface.

16. The passenger transport system of claim 1 , wherein the projection device has a focusing device which is configured to selectively project the at least one symbol to be displayed onto projection surfaces that are spaced apart at different distances.
