Public transport vehicle, including a device for displaying on a window

Abstract

A vehicle includes at least one side bay equipped with a window, and a device for displaying at least one item of information on the window. The display device includes an image projector fastened to a ceiling of the vehicle. The display device emits light rays. A system of at least one mirror is arranged to reflect light rays emitted by the image projector in the direction of the window.

Claims

1. A public transport vehicle comprising at least one side bay equipped with a window, and a display device for displaying at least one item of information on the window, wherein the display device comprises: an image projector, intended to emit light rays, a system of at least one mirror arranged to reflect light rays emitted by the image projector, in the direction of the window, wherein the system of at least one mirror comprises first and second mirrors, the first mirror being arranged to reflect the light rays emitted by the image projector toward the second mirror, and the second mirror being arranged to reflect the light rays reflected by the first mirror, toward the window, and wherein the second mirror is a pixelized mirror.

2. A public transport vehicle according to claim 1, wherein the image projector is fastened to a ceiling of the vehicle.

3. A public transport vehicle according to claim 1, wherein at least one of the mirrors is linked to a mount by movable linking means that enable an adjustment of the position of the mirror by translation and/or by tilting.

4. A public transport vehicle according to claim 1, wherein the first and second mirrors are connected to one another by means of a device enabling the mirrors to be tilted relative to one another.

5. A public transport vehicle according to claim 1, wherein the image projector is at least partially housed in a housing bounded by the ceiling.

6. A public transport vehicle according to claim 1, wherein the bay comprises a film covering the window or integrated into the window, the film forming the projection surface for the image.

7. A public transport vehicle according to claim 6, wherein the film is a holographic film.

8. A public transport vehicle according to claim 1, comprising a plurality of bays, each being equipped with a respective display device.

Description

BRIEF DESCRIPTION OF THE DRAWING

(1) The invention will be better understood upon reading the following description, which is given only as an example and with reference to [FIG. 1] the sole FIGURE attached, schematically depicting a rail vehicle according to one example embodiment of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(2) The FIGURE partially and schematically depicts a public transport vehicle 10, particularly a rail vehicle.

(3) The vehicle 10 comprises a structural body 30 comprising side walls and a ceiling, as well as an arched panel 28.

(4) At least one of the side walls, preferably each side wall, is equipped with at least one bay 14 comprising a window 16.

(5) The vehicle 10 comprises, for at least one of its bays, and preferably for each bay, a respective device for displaying images on the window 16.

(6) The display device comprises an image projector 20 capable of emitting light rays in order to form an image on a projection surface. The image projector 20 is preferably a video projector.

(7) The image may be of any foreseeable type, and for instance may comprise informative text.

(8) The projector 20 is at least partly housed in a housing built into the arched panel 28. The image projector 20 is fastened to the structural body 30 by means of a first mount 32, and first movable fastening means 34 connecting the image projector 20 to the first mount 32. The image projector 20 can be tilted using the first movable fastening means 34.

(9) The projector 20 is oriented to emit light rays opposite the window 16. As an example, a light ray R has been depicted in the FIGURE.

(10) The display device further comprises a system 22 of at least one mirror arranged to reflect light rays R emitted by the image projector 20, in the direction of the window 16.

(11) Advantageously, the system 22 comprises two mirrors, namely a first mirror 24 and a second mirror 26.

(12) The first mirror 24 is arranged to reflect the light rays R emitted by the image projector 20, onto the second mirror 26. The second mirror 26 is arranged to reflect the light rays R reflected by the first mirror 24, onto the window 16.

(13) At least one of the mirrors 24, 26 is linked to a second mount 36 fastened to the structural body 30, particularly to the ceiling, by second movable fastening means 38 that enable an adjustment of the position of the mirror by translation and/or by tilting.

(14) It is therefore possible to adjust the alignment of the mirrors to obtain a satisfactory image on the projection surface.

(15) Advantageously, the second mirror 26 is a pixelized mirror. Such a pixelized mirror makes it possible to enlarge the image and correct the keystone effect caused by the orientation of the projector 20.

(16) Optionally, the keystone effect is also corrected by means of suitable software, within the projector 20.

(17) Advantageously, the first 24 and second 26 mirrors are connected to one another, such as by means of a hinge enabling the mirrors 24, 26 to be tilted relative to one another.

(18) Preferably, the bay 14 comprises a film covering the window 16 or integrated (laminated) into the window 16, the film forming the projection surface for the image. This film is typically a holographic film.

(19) The film enables a better reflection of the image than the window itself, while remaining transparent or substantially transparent. The film therefore forms an effective contact surface.

(20) It will therefore be noted that the mirrors ensure maximum reflection of the luminous flux emitted by the projector 20. There is therefore no loss of luminosity between the projector 20 and the window 16.

(21) It should be noted that the invention is not limited to the previously described embodiment, but may exhibit various additional variants.
