Abstract

PURPOSE:To make a large picture enlargeable to the extent of twice as long as the maximum limitation of height provided in the Road Transport Vehicles Act, by loading the large picture on a car in a way of dividing it into two part, upper and lower parts, while locking the lower part on the car and placing the upper part on the top of the locked lower part in time of picture displaying. CONSTITUTION:After a car is held in horizontality, an internal cylinder 20 of a lift cylinder is extended long to some extent, lifting an upper display part 5 upward, and the lower end of the display part 5 is made so as to cause it to become somewhat higher than the upper end of a lower display part 6. Next, only when an internal cylinder 23 of a tilt cylinder is contracted, an external cylinder 21 of a vertical cylinder is tilted to the right with a bearing 26 as a fulcrum point, and contraction motion of the internal cylinder 23 of the tilt cylinder stops at a position where the upper display part 6 reaches just above the lower display part 6. Under this condition, only when length of the internal cylinder 20 of the lift cylinder is contracted, the upper display part 5 is placed on the lower display part 6 while being positioned by V-type uneven metal devices 28 and 29 so that setup formation for a solidified picture as one body is thus completed. With this constitution, a large picture can be enlarged twice as long as the mandatory loading limitation.

As shown in Fig. 4, after holding the vehicle horizontally on the ground with the outriggers 8, first flip up the roof cover 9 and then extend the inner cylinder 2o of the lift cylinder upward to open the upper display. Lift part 5 upward. At this time, the lower end of the upper display section 6 is made to be somewhat higher than the upper end of the lower display section 6. Next, when the inner cylinder 23 of the tilt cylinder is reduced, the outer cylinder 21 of the vertical cylinder is tilted to the right about the bearing 26, so that the upper display part 5 moves to the right in a suspended state. As shown in FIG. 5, the inner cylinder 23 of the tilt cylinder
Stop the reduction operation. If the length of the inner cylinder 20 of the lift cylinder is slightly reduced in this state, as shown in FIG. It is placed on the lower display part θ while being positioned by the shaped metal fittings 28 and 29, and the assembly of the integrated screen is completed. In order to return from the assembled state to the initial state where they are juxtaposed on the floor surface, the above-mentioned assembly operation is reversed. After assembly, the rear cover 11 is opened and the broadcasting operation is started while maintaining good heat radiation.

The screen is divided into upper and lower parts, and only the upper display part can be moved vertically and horizontally to form an integrated screen. Only one side of the large screen needs to be moved, and the other screen can be fixed. This method has the advantage that it requires less electrical wiring, and it is easier to obtain accuracy than when both screens move relative to each other, and there is less risk of damage due to contact between the screens or misalignment of the screens. For this reason, it is particularly suitable for applications where large display screens are installed at high locations outdoors for the convenience of spectators, and then mounted on vehicles at a low height after use, and have great industrial value. .
