Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention relates to an advertising device for subway car passengers, and particularly to an advertising device that uses the walls of a subway station. Regarding video projection methods.

(Prior Art) Conventional advertising methods in subways include advertisements hung from the ceiling inside the train, advertisements posted on the walls inside the train, and illuminated advertisements installed on the walls inside the station premises.

None of these advertisements are videos, and the illuminated advertisements installed on the walls of station premises are fixed and will become obsolete with the passage of time. However, it would be a hassle to replace it, so I left it as is.

During the long journey between stations, passengers simply look out the dark windows. Recently, long tunnels are being constructed in various places, but there is still no advertising method that uses the walls inside the tunnels.

(Problems to be Solved by the Invention) However, since the above-mentioned conventional advertising medium in subway stations is not a video, it does not attract attention. Long tunnels are becoming more common these days, and passengers feel bored just by looking out the dark windows while passing through long tunnels.

Therefore, the present invention aims to solve the problems of the conventional advertising method described above.The purpose of the present invention is to utilize the wall beside a long subway track and project a video onto this wall using a projection device installed in a vehicle. To provide a video image method in a subway, which prevents passengers in a train from feeling bored while passing through a long tunnel, and which projects advertising media with high advertising effectiveness.

[Structure of the invention]

(Means for Solving the Problems) The present invention for solving the above-mentioned problems includes installing a projection device on the side of a subway car, and projecting a moving image onto the tunnel wall while the subway car is moving through the tunnel so that passengers inside the car can see it. This is what I did.

The ideal place to install the projection device is under the window on the side of the vehicle, from the perspective of wanting the projection angle to be as perpendicular to the wall as possible, but if it is difficult to install, it is recommended to install it above the window.
Or even on the roof.

Possible materials to be projected include a moving image using color film, or a color magic lantern film for advertising.

(Function) The subway video video method of the present invention has a great promotional effect because it can use the large area of unused side walls in long subway tunnels as an advertising medium. Such advertisements are highly effective for passengers in subway cars, who have traditionally been bored.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a subway car, where 1 is a projection device installed below a window on the side of the car, and 1' is a projection device installed above a window of the car. There is more space above the window to install it. The projection angle is also almost the same in both cases.

FIG. 2(A) is a front view of the vehicle, and it can be seen that the above-mentioned projection angle is approximately the same on the lower side of the window and the upper side of the window.

10 indicates the surface of the wall.

FIG. 2(B) shows the projection screen 11 when projected by the projection device 1 or 1' of FIG. 2(A). The dimensions are approximately 2 meters wide and 1 meter high, depending on the size of the window. The distance between the projection equipment and the wall is about 0.7 meters, and the average projection angle is about 40 degrees, but with recent advances in optical technology, it is possible to project distortion-free video onto the wall at this angle. .

Figure 3 (A) is a diagram when projecting using the projector 2 installed below the window on the side of the vehicle, where 3 is a box that stores the projector 2, and 4 is a control that summarizes the electrical system. It's a box. Structurally, when the box 3 is installed below the window, it is attached from the outside due to the position of the seats in the car. Figure 3 (B) shows the case of projecting using projector 2' when the projection device is installed above the window. It can be worn more easily.

Positioning it above the window has advantages in terms of location and operation. 5 indicates the window of the vehicle. When replacing the film, the boxes 3 and 3' are taken out and the film in the projectors 2 and 2' is replaced. The control box 4.4' is disconnected from the electrical system when the boxes 3, 3' are removed. The projector 2°2' is started and stopped by a switch from the driver's cab or conductor's cabin.

The above configuration is disclosed in FIG. That is, 2021 is a socket, which communicates with the power line 22 when the box 3 is attached to the side plate of the vehicle. The main parts of the projector 2 include a power light 23. It consists of a film winding motor 24, film reels 25 and 26, and a plurality of lenses (not numbered). The power line 22 leads to the driver's or conductor's cabin 30, and switches 31,32 control the operation of the projector.

As you can see in Figure 1, for a standard subway car,
- You can install 3 projectors on one side of the vehicle and 6 projectors on both sides. The walls of the subway station where the video will be projected will be painted white.

The present invention is not limited to the above-mentioned embodiments, but can be implemented in any appropriate manner by making appropriate design changes.

〔Effect of the invention〕

As explained above, according to the present invention, a projection device is installed near the window on the side of a subway car, and a moving image is projected onto the wall of the subway premises. However, the device of the present invention eliminates the feeling of boredom. The promotional effects of videos are extremely large, as they can take advantage of large unused areas such as walls within the premises. Changing the film is also easy because the box containing the projection device can be pulled out.
