Abstract

The application discloses an end cover (30,40) of an anti-clamping device for an apron board, which includes a body (32,42) made of a transparent material or a translucent material; one or multiple LED lighting lamp(s) (36) is(are) provided in the interior of the body; and a coupling member formed on at least a part of the body (32,42), which cooperates with at least a part of the anti-clamping device to form a detachable connection between the body and the anti-clamping device, and the size from a first end of the body (32,42) to a second end thereof is gradually reduced so as to form a smooth transition between the apron board and the anti-clamping device. Providing the end cover reduces the clearance between a step and the apron board, provides enhanced lighting effect in the vicinity of a boundary from a comb to the step, reduces the cost of installation and maintenance, and does not reduce the strength of the apron board.

First claim

The invention claimed is:

1. An end cover of an anti-clamping device for an apron board, comprising:
a body made entirely of a transparent material or a translucent material, one or multiple LED lighting lamp(s) provided in the interior of the body; and
a coupling member formed on at least a part of the transparent or translucent body, which cooperates with at least a part of the anti-clamping device to form a detachable connection between the body and the anti-clamping device,
wherein, the size from a first end of the transparent or translucent body to a second end of the transparent or translucent body is gradually reduced so as to form a smooth transition between the apron board and the anti-clamping device.

2. The end cover according to claim 1 , wherein the coupling member is connected to the at least a part of the anti-clamping device through one of a plug-in connection, a buckling connection, an interference fit connection, and a bonding connection.

3. The end cover according to claim 2 , wherein the one or multiple LED lighting lamps are placed on at least one of a support in the interior of the body or an inner surface of the body.

4. The end cover according to claim 3 , wherein the multiple LED lighting lamps are of different colors.

5. The end cover according to claim 4 , wherein the multiple LED lighting lamps are placed in a certain interval, and the multiple LED lighting lamps flash alternately during operation.

6. The end cover according to claim 1 , further comprising a through hole or a half through hole located in the central part of the body, for accommodating a fastener for further fixing the end cover and the anti-clamping device.

7. The end cover according to claim 1 , wherein a distance between the end cover and a corresponding step-comb intersection line is between 50-150 mm.

8. The end cover according to claim 1 , wherein the anti-clamping device comprises any one of a single-row anti-clamping device and a double-row anti-clamping device.

9. An escalator system, comprising the end cover of an anti-clamping device for an apron board according to claim 1 .

10. A travelator system, comprising the end cover of an anti-clamping device for an apron board according to claim 1 .

11. An end cover of an anti-clamping device for an apron board, comprising:
a body made entirely of a transparent material or a translucent material, one or multiple LED lighting lamp(s) provided in the interior of the body; and
a coupling member formed on at least a part of the transparent or translucent body, which cooperates with at least a part of the anti-clamping device to form a detachable connection between the body and the anti-clamping device;
a through hole or a half through hole located in the central part of the body, for accommodating a fastener for further fixing the end cover and the anti-clamping device;
wherein, the size from a first end of the transparent or translucent body to a second end of the transparent or translucent body is gradually reduced so as to form a smooth transition between the apron board and the anti-clamping device;
wherein the coupling member is connected to the at least a part of the anti-clamping device by at least one of a plug-in connection, a buckling connection, an interference fit connection, and a bonding connection;
wherein the one or multiple LED lighting lamps are placed on at least one of a support in the interior of the body or an inner surface of the body;
wherein the one or multiple LED lighting lamps are of different colors;
wherein the one or multiple LED lighting lamps are placed in a certain interval, and the one or multiple LED lighting lamps flash alternately during operation;
wherein a distance between the end cover and a corresponding step-comb intersection line is between 50-150 mm;
wherein the anti-clamping device comprises one of a single-row anti-clamping device and a double-row anti-clamping device.
