Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an illuminated advertising panel that illuminates advertising material printed on a transparent or translucent film from the back side to make the advertising material stand out, and is especially installed in train cars such as Shinkansen bullet trains It relates to a thin and vibration-resistant illuminated advertising panel that can be used.

[0002]

[Prior art]

 The illuminated advertising panel is one of the most effective and effective advertising media in street advertising, and is widely installed in department stores, showrooms, and station premises. Earlier illuminated advertising panels used the same hot cathode tubes as fluorescent lamps as light sources, and the entire panel was thick, at least 50 mm or more, and it was hardly protruding from the wall. It was often installed by making a hole in the wall and embedding it.

[0003]

[Problems to be solved by the invention]

 Railway officials came to think of the fact that many of the illuminated advertising panels installed at station yards could not be installed on trains. However, the wall of the vehicle was so thin that it could be used as a door pocket for the sliding door at the entrance, making it impossible to pierce the wall and bury the panel as before.

The present invention has been made in view of the above-described circumstances, and has as its object to provide an illuminated advertising panel for a vehicle that is thin and resistant to vibration.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the illuminated advertising panel for a vehicle according to the present invention includes an edge light type light guide plate and a light guide plate on a base of a thin panel body in which a front door having a window is opened and closed by a hinge. A cold-cathode tube that illuminates the end face is fixed so that it is pressed down by a mounting bracket with a cushioning material in between, and two transparent plates with an advertising object are set on the light guide plate in the mounting bracket. And a light reflecting member inside the mounting bracket, so that the total thickness of the panel body is 20 mm or less.

[0006]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the illuminated advertising panel of the present invention is configured based on a panel body 4 having a front door 2 with a window 1 attached to the upper edge of a base 5 via hinges 3 and 3. You. This illuminated advertising panel is designed under the concept of being made thinner and resistant to vibration, and installed in a Shinkansen vehicle. The panel body is only 16 mm thick. In addition, a surface light emitting device using a light guide plate 6 and a cold cathode tube 7 is incorporated.

[0007] The internal configuration of the panel body 4 will be described. A light guide plate 6 having a size almost full is mounted on a base 5, and both sides of the light guide plate 6 have a diameter of a light source. A thin cold cathode tube 7 is provided in close proximity. The light guide plate 6 is an edge light type, is made of a methacrylic resin plate having a thickness of 5 mm, has a dot pattern printed on the back side, and further has a light reflection sheet 15 adhered thereon. A light diffusing film 16 is adhered to the light emitting element. In the light guide plate 6, the light from the cold cathode tubes 7, 7 entering from the left and right end surfaces is transmitted and diffused in the plate, and the front surface emits light uniformly. The cold cathode tube 7 is made of a thin glass tube having a diameter of 3 mm, and is held at both ends by a block-shaped cushion material 8a made of hard rubber.

The light guide plate 6 and the cold cathode tubes 7 are pressed down from the surroundings by four mounting brackets 9 a, 9 b, 9 c, 9 d on the upper, lower, left and right sides, and are fixed to the base 5 by screws 18. The mounting bracket is made by bending a stainless steel plate, and the top and bottom two and the left and right two have slightly different shapes.

As shown in FIG. 2, the upper and lower mounting brackets 9 a and 9 b include a key-shaped holding portion 19 for holding the edge of the light guide plate 6 and a translucent advertisement 10 with two transparent acrylic plates 11. , 11 and a groove 12 for setting the one sandwiched between them are formed doubly. A soft cushion material 8b made of a polyethylene foam material is adhered to the surface of the light guide plate 6 on the inner side of the holding portion 19, which is in contact with the front surface. The cushion material 8c is stuck. A hard rubber cushion member 8c is also provided on the inner surface side of the lower groove portion 12. A reflection film 13 as a light reflecting member is attached to the upper and lower end surfaces of the light guide plate 6. Reference numeral 20 in the figure denotes a magnet catch for receiving the front door 2.

As shown in FIG. 3, the left and right mounting brackets 9 c and 9 d are displaced from each other by a key-shaped holding portion 19 that holds an edge of the light guide plate 6 and a transparent acrylic plate 11 that sandwiches the advertisement 10. It has a guide wall 21 for preventing movement. The cushion member 8 a holding both ends of the cold cathode tube 7 fits into the holding portion 19, and serves as a cushion for both the cold cathode tube 7 and the light guide plate 6. On the surface corresponding to the front surface of the light guide plate 6, a soft cushion material 8b made of a polyethylene foam material is provided. In addition, a reflection film 13 is attached to a surface of the holding portion 19 facing the inner surface of the light guide plate 6 so that the light from the cold-cathode tube 7 is incident on the light guide plate 6 without being reflected.

On the back side of the panel body 4, there are provided a converter 22 for converting an alternating current to a direct current and an inverter unit 23, which are wired from the inverter unit 23 to the electrodes of the cold cathode tubes 7. When the panel body 4 is mounted on the wall surface 24 in the vehicle, a hole is provided in the wall surface 24 so that the converter 22 and the inverter unit 23 can be completely fitted, and the panel body 4 is directly mounted on the wall surface 24. If the converter 22 and the inverter unit 23 are placed separately from the panel body 4, the panel body 4 can be mounted without making any holes in the wall surface 24.

[Effect of the invention]

 The vehicle's illuminated advertising panel of the present invention can achieve an unprecedented thickness of 20 mm or less by adopting a surface-emitting method using an edge light type light guide plate and cold cathode tubes. Was. In addition, since the light guide plate and the cold cathode tubes are held through the cushioning material, the light guide plate and the cold cathode tubes do not break down even when subjected to the vibration of the train. The mounting bracket has a light reflecting member inside, and also serves as a reflector. Also, the front door can be opened and closed to easily replace advertising material.
