Abstract

An escalator, a moving walkway or an elevator cage includes at least one illuminable transparent panel. The illuminable transparent panel has a construction containing a plurality of layers. The two side surfaces of each layer are bounded in the area dimension thereof by an edge region. The layers of the construction are arranged with the side surfaces against one another. The layer sequence of the construction is defined, wherein a first layer is a first glass pane, a second layer is a first transparent polymer layer, a third layer is a second glass pane, a fourth layer is a transparent polymer material plate containing light-dispersing particles, a fifth layer is a third glass pane, a sixth layer is a second transparent polymer layer and a seventh layer is a fourth glass pane.

First claim

We claim:

1. An illuminable transparent panel for illumination by at least one light source arranged at an edge region of the panel, comprising a plurality of layers each having opposed side surfaces with the side surfaces of adjacent layers being in contact with each other and an edge region, the layer edge regions forming said panel edge region, the layers comprising:
a first layer comprising a first glass pane;
a second layer adjacent to the first layer, the second layer comprising a first transparent polymer layer;
a third layer adjacent to the second layer, the third layer comprising a second glass pane;
a fourth layer adjacent to the third layer, the fourth layer comprising a transparent edge-illuminable polymer material plate;
a fifth layer adjacent to the fourth layer, the fifth layer comprising a third glass pane;
a sixth layer adjacent to the fifth layer, the sixth layer comprising a second transparent polymer layer; and
a seventh layer adjacent to the sixth layer, the seventh layer comprising a fourth glass pane.

2. The illuminable transparent panel of claim 1 , the first glass pane, the transparent polymer layer, and the second glass pane forming a composite glass pane.

3. The illuminable transparent panel of claim 1 , the third glass pane, the second transparent polymer layer, and the fourth glass pane forming a composite glass pane.

4. The illuminable transparent panel of claim 1 , the second glass pane or the third glass pane comprising a hardened safety glass pane.

5. The illuminable transparent panel of claim 1 , further comprising a frame profile member, at least one of the edge regions of the first, second, third, fourth, fifth, sixth or seventh layers being arranged against the frame profile member.

6. The illuminable transparent panel of claim 1 , further comprising a frame profile member, the frame profile member encircling the edge regions of the first through seventh layers.

7. The illuminable transparent panel of claim 6 , the frame profile member comprising a light source passage.

8. The illuminable transparent panel of claim 1 , the illuminable transparent panel being positioned adjacent to an additional illuminable transparent panel.

9. The illuminable transparent panel of claim 1 , further comprising a seal for an inter-layer gap, the gap seal having a joint depth between 0.2 millimeters and 20 millimeters.

10. The illuminable transparent panel of claim 9 , the gap seal having a joint depth between 8 millimeters and 12 millimeters.

11. The illuminable transparent panel of claim 9 , the seal comprising a cut-out for a light source and for the fourth layer.

12. The illuminable transparent panel of claim 1 , further comprising a light source, the light source having a settable light intensity, a settable color tone, or a settable color saturation.

13. The illuminable transparent panel of claim 12 , further comprising a sensor, the sensor being configured to detect a light intensity, a color tone, or a color saturation of the panel and to send a sensor signal to a control unit.

14. The illuminable transparent panel of claim 13 , the panel being adjacent to an additional panel, the panel being a master panel and the additional panel being a servant panel, a light setting of the servant panel being based by the control unit on a light setting of the master panel.

15. The illuminable transparent panel of claim 1 , further comprising a motif film or printing on the first layer or the seventh layer, the motif film or the printing being backlit when the panel is illuminated.

16. An escalator or moving walkway, comprising:
a support structure;
a step belt or plate belt arranged in the support structure;
an illuminable transparent panel arranged at the support structure and extending along a longitudinal side of the step belt or of the plate belt, the illuminable transparent panel comprising

a first layer, the first layer having a first set of opposing sides and being bounded by a first edge region, the first layer comprising a first glass pane, a second layer, the second layer having a second set of opposing sides and being bounded by a second edge region, the second layer being adjacent to the first layer, the second layer comprising a first transparent polymer layer,
a third layer, the third layer having a third set of opposing sides and being bounded by a third edge region, the third layer being adjacent to the second layer, the third layer comprising a second glass pane, a fourth layer, the fourth layer having a fourth set of opposing sides and being bounded by a fourth edge region, the fourth layer being adjacent to the third layer, the fourth layer comprising a transparent edge-illuminable polymer material plate, a fifth layer, the fifth layer having a fifth set of opposing sides and being bounded by a fifth edge region, the fifth layer being adjacent to the fourth layer, the fifth layer comprising a third glass pane, a sixth layer, the sixth layer having a sixth set of opposing sides and being bounded by a sixth edge region, the sixth layer being adjacent to the fifth layer, the sixth layer comprising a second transparent polymer layer, and a seventh layer, the seventh layer having a seventh set of opposing sides and being bounded by a seventh edge region, the seventh layer being adjacent to the sixth layer, the seventh layer comprising a fourth glass pane; and
a light source arranged at an edge of the illuminable transparent panel.

17. An elevator cage, comprising:
a cage frame;
a cage floor connected to the cage frame;
an illuminable transparent panel connected to the cage frame, the illuminable transparent panel comprising, a first layer, the first layer having a first set of opposing sides and being bounded by a first edge region, the first layer comprising a first glass pane, a second layer, the second layer having a second set of opposing sides and being bounded by a second edge region, the second layer being adjacent to the first layer, the second layer comprising a first transparent polymer layer, a third layer, the third layer having a third set of opposing sides and being bounded by a third edge region, the third layer being adjacent to the second layer, the third layer comprising a second glass pane, a fourth layer, the fourth layer having a fourth set of opposing sides and being bounded by a fourth edge region, the fourth layer being adjacent to the third layer, the fourth layer comprising a transparent edge-illuminable polymer material plate,
