Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a large screen mobile vehicle.

(Prior art) As a conventional large screen moving vehicle,
What is described in Publication No. 190035 (Figure 18)
The configuration is such that a roof-like wing 51 that covers the upper part from one side of the loading platform 50 is swingable to open and close, and the loading platform 50 has a lower display section 52 on the other side and a screen on one side. The upper display section 53 and the lower display section 52 and their adjacent upper ends are connected to each other via a hinge 54 and arranged on one side, and a push-up element 55 is arranged so as to be erected so as to face the same direction. The upper display section 53 is connected to the upper display section 53 so that the upper display section 53 is inverted and placed on the upper surface of the lower display section 52.

When assembling a large screen, after swinging the wings 51 open, the upper display section 53 is inverted and placed on the upper surface of the lower display section 52, and the upper and lower display sections 52,
53 can be combined to assemble a large screen.

Furthermore, during storage, the upper and lower display sections are stored and protected by the wings after the above-mentioned assembly procedure is reversed.

However, in the above-mentioned large screen moving vehicle, the large screen hangs down from one side of the loading platform and is located on the other side, so the large screen is located deep from the side of the vehicle body. In particular, there is a problem in that the visible range of the large screen is narrowed by the front and rear wall panels.

In order to solve this problem, a lower display section 52 is installed on one side of the loading platform 50 with the screen facing in the same direction, and an upper display section 53 on the other side is placed on top of this lower display section 52. Although it is conceivable that the upper display section 53 can be configured so that it can be mounted upside down, the wing 51 and the cover on the back side become an obstacle when the upper display section 53 is turned over.
Impracticable.

On the other hand, if the large screen protrudes to the side of the cargo bed, there will be no problem with the visible range of the screen, but on the other hand, there will be problems with only the large screen protruding from the side of the vehicle body, and problems with weight balance. There are problems with stability and uneven appearance. (Refer to Japanese Unexamined Patent Publication No. 57-111580.) Therefore, an upper display section is provided on the loading platform so as to be movable up and down, and a deck is provided so as to be slidable laterally with a slide element, and the lower display section is attached to the deck above the upper display section. It is considered to be able to move freely under the display,
The large screen formed by both display sections can be brought closer to the side of the vehicle body. However, the presence of a deck and sliding element to make both the upper and lower display parts slidable limits the height of both display parts to a low level, and as a result, this is especially true for large screens where the top and bottom parts are slightly smaller. There is a problem that it can only be loaded. (Tokukai Akira
(Refer to Publication No. 62-262085) (Problem to be solved by the invention) The problem to be solved is that in an all-weather wing opening/closing type, the video display on the large screen consisting of the upper and lower display sections is not displayed on the side of the vehicle body. The size and especially the vertical height of the upper and lower display parts, that is, the large screen, can be configured to be the maximum height between the ceiling of the wing and the loading platform. The aim is to provide a large screen moving vehicle.

(Means for Solving the Problems) In the large screen moving vehicle of the present invention, the lower display part is erected on one side of the loading platform with the screen facing one side, and the upper display is placed on the other side. The display parts are arranged with the screen facing to the other side, with both the lower display part and its adjacent upper end being pivoted and connected by a rotating shaft, and the upper display part is pushed up by a push-up element. By the operation of the push-up element, the upper display part is reversed about the rotation axis as a fulcrum and is formed so as to be able to be mounted on the upper surface of the lower display part, and the front and rear walls of the loading platform are moved by slide elements relative to the loading platform, A wing opening/closing element is formed so that it can be freely extended to an extended position on the other side without interfering with the reversing operation of the display unit, and covers the upper side of the loading platform between the front and rear walls. It is characterized by being swingable and openable to an open state that does not hinder the feeding operation.

In addition, the device of the present invention has a storage room for power reels, etc., and an operation room for video, etc., in front and behind the upper and lower display sections of the loading platform, and the upper and lower display sections are located on the front and rear walls of the loading platform. It may also be of elongated configuration spanning between sections.

(Function) When assembling a large screen, the wing swings under the driving force of the opening/closing element and opens to an open state that does not prevent the front and rear walls from sliding to the other side.

Then, the front and rear walls receive the driving force of the slide element, and slide together with the wings to the extended position on the other side of the loading platform, and are extended to the extended state that does not interfere with the reversing operation of the upper display section.

In the extended state, the upper display body is reversed and pushed up by the push-up element, and is placed on the upper surface of the lower display body to join together.

Next, the front and rear walls and wings are moved back by the sliding element, and the large screen consisting of the upper and lower display sections in the combined state is surrounded by the front and rear walls and wings at the front, rear, and upper sides, and is connected to the side of the vehicle. It is assembled flush and ready for video display and transmission.

Moreover, when storing, the assembly is performed in the reverse order.
