[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rear display signal device, and more particularly to a signal device that is attached to a glass plate of a rear window of a vehicle and transmits a greeting signal to another vehicle behind the vehicle that has passed while traveling.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, a vehicle such as a passenger car is often overtaken by another vehicle traveling ahead while traveling on a highway or a highway. At this time, a lane change signal is used to notify a vehicle behind him of the lane change, and a lane change signal is used to notify the lane change even when the vehicle ahead of the vehicle is overtaken. At this time, it is common among young people to greet overtaking vehicles by flashing the rear lamps of their own vehicles.

[0003]

[Problems that the device is trying to solve]

 The above-mentioned conventional greetings to the rear vehicle after passing are not limited to simple blinking of the lamp, and a smarter, smarter, and smarter greeting method is required. Therefore, an object of the present invention is to provide a signaling device capable of displaying a nice, smart, and cool greeting signal to a vehicle behind after overtaking while traveling.

[0004]

[Means for solving problems]

 The above object is achieved by the present invention described below. That is, the present invention comprises a colored film that can be attached to the glass surface of the rear window of a vehicle and a light source that illuminates the colored film from the back side. The rear display signal device is characterized in that a non-colored region corresponding to the number is provided.

[0005]

[Action]

 A colored film was attached to the glass surface of the rear window of the vehicle, and the colored film was provided with a non-colored area corresponding to signals such as letters, symbols, and patterns, and it was overtaken by shining light from behind. You can greet the vehicle behind you with a signal such as letters.

【Example】

 Next, the present invention will be described more specifically with reference to examples. FIG. 1 is a diagram schematically illustrating an example of a rear display signal device of the present invention. As shown in FIG. 1, the present invention can be attached to the surface of a glass 2 of a rear window of a vehicle 1 such as a passenger car. The colored film 3 and the light source 4 that illuminates the colored film 3 from the back side. The colored film 3 corresponds to signals such as arbitrary characters, symbols, and patterns as shown in FIGS. 2 and 3. The non-colored area 5 is provided.

In the present invention, the vehicle 1 that can be equipped with the rear display signal device of the present invention is not limited to a general passenger car, but may be a truck, a bus, or any vehicle having a rear window glass. Is not limited at all. The colored film 3 used in the present invention is, for example, a transparent film (or sheet) such as a polyester film, which is colored so as to be thin and nearly translucent, and light from the outside easily enters ( That is, the outside can be seen well from the inside), but light is difficult to radiate from the inside to the outside (that is, the inside cannot be seen or cannot be seen from the outside), and it is the area around passenger cars used by many young people. It is widely used by being attached to the inner surface of the glass, and can be easily obtained from automobile accessory stores and used.

As shown in FIGS. 2 and 3, the colored film 3 is provided with a non-colored area 5 corresponding to a signal such as an arbitrary character, symbol, or pattern. The non-colored area 5 can be formed extremely easily by, for example, cutting out the film with a cutter knife or the like at a necessary portion. Further, a transparent film may be laminated on the cut-out colored film 3 for the purpose of reinforcement. Since the colored film 3 is attached to the rear window glass 2 which is inclined, the non-colored region 5 is preferably a vertically long character or the like so that it can be easily seen from the rear. The size of the colored film 3 is preferably laminated on the entire surface of the rear window glass 2, but may be partial instead of the entire surface. The sticking method may be a normal thin paste, or may be simply wet with a liquid. When the colored film 3 is a thick sheet and has a certain degree of rigidity, it may be attached to the rear window glass 2 with a suction cup or a double-sided adhesive tape.

The light source 4 provided behind the colored film 3 is an incandescent light bulb in the embodiment shown in FIGS. 1 and 2, and only one light bulb is shown in the drawings. May be in parallel. In addition, it is preferable to provide a reflector having an appropriate curvature behind the light bulb so that the light rays emitted from the light bulb are concentrated only in the direction of the colored film 3. The light source 4 is, of course, connected to the battery of the vehicle via a switch provided on the dashboard surface in front of the driver's seat, and is turned on or blinked for a few seconds by turning on the switch. .

The example shown in FIG. 3 is another embodiment of the present invention, and this rear display signal device has a coloring film provided with an uncolored region 5 corresponding to a signal, as shown in a cross section of FIG. 2b. This is an example in which a light emitting display element composed of an electroluminescence layer 7 sandwiched between a pair of transparent electrodes 6 and 6 ′ is used as a light source 4 on the back surface of the frame 3, and a voltage is applied to the element. As a result, the element emits light, light is emitted from the non-colored area 5 in the colored film 3, and a signal can be transmitted to another vehicle behind the vehicle that has passed. In this case, the electroluminescent layer may be formed in the same pattern as the non-colored region 5 of the colored film 3, which allows a clear signal to be emitted. Further, in place of the electroluminescence layer, a liquid crystal display element that is colored / decolored by turning on / off a voltage is provided, and the incandescent lamp shown in FIGS. 1 and 2 is used as a backlight at the rear side to display a color signal. It is possible.

Although the main part of the present invention has been described with reference to the embodiments shown in the drawings, it is preferable that the colored film used in the present invention is usually colored in dark purple or brown in order to make the signal clear. The non-colored area of the colored film described above is usually colorless and transparent, but may be colored in other light colors such as pale yellow, red, and blue. By doing so, it is also possible to transmit an optical signal, which is colored to some extent, to the vehicle behind which has passed. As the light source, an incandescent light bulb and an electroluminescence layer are mentioned, but it is needless to say that any light source such as a fluorescent lamp, a halogen lamp, a sodium lamp, a mercury lamp, and a laser beam may be used.

[0012]

【effect】

 According to the present invention as described above, a colored film is attached to the glass surface of the rear window of a vehicle, and the colored film is provided with a non-colored area corresponding to a signal such as an arbitrary character, symbol, or pattern, and a light is emitted from the rear. By illuminating, you can greet a passing vehicle behind you with a signal such as letters.
