Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a vehicle-mounted display device with a stage that serves both as a large screen display device and a stage.

Conventional configurations and their problems Conventionally, in order to carry a large display device onto a vehicle, transport it to the destination, and assemble it for use on-site, the dimensions during transportation must exceed those stipulated in accordance with the safety standards for road transportation vehicles. Since this was not possible, the screen had to be made smaller, which was inconvenient as a screen for large audiences. However, recently, attempts have been made to divide the screen to make it smaller during transport, and then enlarge it when in use to make it larger. However, when using such a large screen, it is required to have a structure that is easy to see as a screen, easy to use as a stage for greetings by the presenter, and convenient to accommodate in a transport vehicle. However, until now there was nothing suitable for this kind of use.

Purpose of the invention It is an object of the present invention to eliminate the inconveniences of the above-mentioned conventional examples and to provide a display device with a stage that is suitable for both a large screen and a stage.

Structure of the Invention In order to achieve the above object, the present invention includes a plurality of display devices that are stacked vertically at the back of the loading platform to form an integrated screen in front when broadcasting images, and a roof cover that covers the upper part of the integrated screen. A stage space is formed in front of the integrated screen by a pair of shielding plates that are attached to the roof cover or the ends of the display screen by a hinge or the like and surround the left and right sides of the integrated screen when opened, and a floor surface. It is configured as follows.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. In Figure 1, 1 is the driver's cab of the transport vehicle, 2
3 is an equipment storage room, 3 is an operation room for assembling images or screens, and 4 is a loading platform, in which a stage display device is housed, surrounded by a roof cover 6 and a tilt 6, as will be described later. Fig. 2 shows the display device in an assembled state, where 7 is an antenna, 8 is a lifting device using hydraulic pressure or the like to raise and lower the display device in the vertical direction as described later, and 9 is an upper display section (device ), 10 is a lower display section (device), 11 is an upper decorative board, 12 is a lower decorative board, 13 is an outrigger, and 14 is a floor surface of the loading platform. Figure 3 A and B and Figure 4 A and B are
Two embodiments of the screen assembly mechanism are shown, in which 15 is a hinge and 16 is a side cover.

Next, the operation will be explained using FIGS. 2 to 4. When the upper display section 9 and the lower display section 10 are transported (moved) as shown in FIG.
They are mounted inside the loading platform 4 so as to be juxtaposed on the floor surface 14. When the vehicle arrives at the destination, the roof cover 5 is flipped upward around the hinge 15, and the upper display section 9 is stacked above the lower display section 10 to form an integrated screen. As a method for loading,
In FIG. 3, the upper display section 9 is first moved upward and then to the right, and the items are loaded as shown in FIG. 3B. At this time, the lower display section 10 is fixed. On the other hand, in FIG. 4, the storage shown in FIG. 4A is similar to FIG. 3A, but as shown in FIG. to move the lower display part 10 horizontally to the right into the empty space, and if necessary,
Using means for smooth movement such as rails and rollers (not shown), the screen is inserted under the upper display section 9 that has been lifted upward, and the assembly (loading) of the screen is completed. Although the configurations shown in FIGS. 3 and 4 differ in the intermediate assembly process, their appearance after loading is basically the same. All have in common that, after loading, a space 16 is formed in front of the front surface of the display section (left side in FIGS. 3 and 4). When viewed from the front, the screens stacked in this manner are shown in Figure 2.

Next, each pair of upper decorative board 11 and lower decorative board 12
When opened forward about the hinges provided at the ends of the upper and lower display boards, the roof cover 5, upper and lower display sections 11 and 12, upper and lower display sections 9,
10. A front stage space surrounded by a floor surface 14 appears. In order to improve the effectiveness of the use of the stage,
As shown in FIG. 5, a part of the stage, for example, a lower display part, is installed to provide lighting equipment 17 and 18 that illuminate the stage from above or below, and to use a microphone 19 for greetings and performances on the stands. Electrical outlet (connector) for connecting a microphone etc. at the bottom of 10
20, or as shown in FIGS. 5 and 6, a curtain 22 may be provided that covers or opens and closes the middle or front of the stage via a curtain rail 21 provided under the roof cover 5. Note that 23 is an audio speaker. Also, upper and lower decorative boards 11,1
2, one end of which is the upper and lower display parts 9 and 10, respectively.
Although an example is shown in which it is fixed, the roof cover 5 may be used as the fixed location so that it can be accommodated during movement. According to the above configuration, by surrounding the upper and right sides of the floor surface 14 with the shield formed by the left and right upper and lower decorative panels 11 and 12 and the upper roof cover 5, the front stage space 16 partitioned off from the outside world is created. This makes it possible to concentrate the audience's attention on the upper and lower display sections 9 and 10, while hiding the lifting device 8 necessary for vertical movement of the display sections from the audience's line of sight. Furthermore, by shielding the front of the screen from external light, the display screen can be easily viewed. Furthermore, since all of the above-mentioned screens are stored inside the loading platform after use, they have the advantage that they do not interfere with transportation.

Effects of the invention As explained above, according to the invention, it is convenient to use not only as a large display screen for images, but also as a stage space, and is not easily affected by ambient light. Therefore, it can be used for both purposes, and has a synergistic effect of expanding its use as a vehicle-mounted large screen device.
