Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to multi-vision configurations.

[0002]

2. Description of the Related Art The conventional multi-vision method used in leasing is a core unit-stacking multi-vision method in which a projection unit corresponding to a unit screen is housed together with a unit squiline in a single housing. Align the front of the screen with the core unit,
A large-screen multi-vision is configured by stacking multiple units on top and bottom. This large-screen multi-vision transports, stacks, and unloads in core units to disassemble and assemble, and can transport, stack, and unload in a relatively short time for a large screen. It has the characteristics that can be done.

As an example of this kind of multi-vision, there is a projection image device and an assembling device disclosed in Japanese Patent Laid-Open No. 4-113789.

[0004]

In the example of the prior application of the above-mentioned core unit stacking method, it suffices that the screen surfaces of the core units are aligned and piled up for installation, and the core units are piled up and down for removal. The feature is that assembly and disassembly can be completed in a short time.

However, the size of the core unit itself is about 88 cm in width, 67 cm in height, 130 cm in depth, and about 10 in weight.
Since it is 0 kg, it requires a machine such as a forklift to handle it, or multiple people are needed at one time, so disassembling and assembling time is relatively short, but a large number of people temporarily need to be input. Then, there was a problem that labor costs were required.

In addition, since the core unit stacking type multi-vision is formed in a cabinet for each set of one screen unit and one projection unit, the number of structural parts is large as a result. ing.

It is an object of the present invention to provide a multi-vision structure which is easy to disassemble and assemble and has a small number of constituent parts.

[0008]

In order to achieve the above object, in the present invention, a cabinet of two or three core units that are in contact with each other vertically is integrally formed, and the frame structure of the cabinet is aligned left and right and up and down. The projection unit corresponding to one core unit is mounted on each set of integers, and the screen unit corresponding to each projection unit is mounted.

[0009]

Since the cabinets of the plurality of core units are integrated, the stacking man-hours at the time of installation can be reduced by about half, and the manufacturing man-hours that account for most of the cabinet manufacturing cost can be reduced by about half.
