Description

[Detailed Description of the Invention] The present invention relates to an assembly type wide screen that can be disassembled and assembled freely.

Recently, special screenings are often held on outdoor stages, halls, etc., and for this purpose, an ultra-wide screen, for example, 2.4 m in length (vertical length) and 10,772 m in width, is required. Sometimes.

When such an ultra-wide screen is required, conventionally, a large screen holding frame is assembled on-site using pipe materials etc. at the location where the wide screen will be installed.
A cloth screen made of a cloth of a size corresponding to the required screen size and coated with a vinyl chloride reflector is prepared separately, and this cloth screen is rolled up and transported to the site, and then used as described above. It was designed to be attached to a screen holding frame.

However, the above-mentioned conventional device has the following problems.

Namely, (1) It was very troublesome to install a large screen holding frame and to dismantle it after use.

■ Because the screen was made of cloth, the screen surface was flat after installation, but in this case, the brightness during projection differed greatly between the top and bottom edges of the screen and the center, making it extremely difficult to see. It had become.

■ When screens of different sizes, especially widths, were requested, a screen holding frame and cloth screen of the requested size had to be prepared each time.

■ Cloth screens are not durable, so
Currently, they are disposable after only one use.

The present invention relates to an assembly type wide screen that solves the above-mentioned problems at once, and is characterized in that the wide screen is provided as a unit.

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

Click on Figure 1, 1 is the completed wide screen,
For example, the vertical dimension t is 2.4 m, and the horizontal dimension is 10 yx.

Such a screen 1 is constructed by connecting ten screen units 2 to each other in the horizontal direction, and after use, it can be disassembled into each screen unit 2, that is, into ten pieces.

As shown in FIG. 2, each screen unit 2 is composed of a frame 3 and a screen plate 4 integrated with the frame 3.

The frame 3 is configured to be self-supporting by framing frame materials such as angle materials or pipe materials, and auxiliary legs 5 are retractably provided within the frame 3 in order to enhance the self-supporting effect.

Among the frame members constituting the frame 3, the pair of left and right vertical frame members 3a located at the front are as described below.
Since the screen plate 4 is curved in the vertical direction so as to be concave toward the rear, it is curved accordingly.

Of course, the horizontal length of the frame 4 is Li2O, and the vertical length is t.

On the other hand, the screen plate 4 includes, for example, an intermediate body layer 6, a screen surface layer 7 that is laminated and integrated on the front surface of the intermediate body layer 6, and a deformation prevention back layer 8 that is laminated and integrated on the rear surface of the intermediate body layer 6. It is constructed as a layered structure.

The intermediate main body layer 6 is intended to provide strength to the screen plate 4 itself, and is considerably thick, and is made of, for example, a board material.

The screen surface layer 7, which becomes the projection surface, is made of, for example, white vinyl chloride resin, and has a thickness of 500 μm.
It is considered to be a degree.

Further, the back layer 8 is made of, for example, black vinyl chloride resin.

The screen plate 4 has an arcuate shape with a radius of about 50 rn, and is curved in the vertical direction so as to be concave toward the rear.

In addition, it is preferable that the surface of the screen surface layer 7 is made into a matte finish, and is also processed with a large number of lines that extend in the vertical direction and are uneven in the horizontal direction, that is, lenticular processing (constituting a so-called Kamapoko lens). In fact, such a screen surface layer 7 can be obtained, for example, by rolling a vinyl chloride board.

The screen unit 2 as described above is constructed by applying the rear surface of the screen plate 4 to the front surface of the frame 3, and attaching screws 9, for example.
It can be obtained by fixing it at its upper and lower four corners using

In order to minimize the presence of the screws 9, it is preferable to attach black borders 4a to the upper and lower edges of the screen plate 4.

A wide screen 1 as shown in FIG. 1 can be obtained by connecting the screen units 2 as described above to each other in the horizontal direction.

To connect the screen units 2, as shown in FIGS. 3 and 4, the opposing frame members of a pair of adjacent screen units 2 are connected by bolts 10, for example.
This can be done by fixing using a fixing tool such as a nut 11 or the like.

Of course, after use, each screen unit 2 can be disassembled by releasing the bolts 10 and nuts 11.

At Tokoguchi, while the screen unit 2 is transported between its storage location and the installation location of the wide screen 1 by vehicle, it must be manually transported from the storage location to the vehicle and from the disassembled vehicle to the installation location. However, since the screen unit 2 is extremely small and lightweight, it can be carried around by only one person M, as shown in FIG.

At this time, when the screen unit 2 is carried so that it is positioned toward the human body, the screen unit 2 does not come into contact with the human body and is extremely easy to carry, since the central part of the screen plate 4 is concave.

Although the embodiments have been described above, the present invention is not limited thereto, and includes, for example, the following cases.

■ The frame 3 may be made of plate material, etc.
It may be equipped with a handle or casters for convenient portability.

(2) The vertical and horizontal dimensions of the screen unit 2 can be set as appropriate in consideration of ease of carrying.

■ Screen unit 2 can be used not only horizontally but also vertically.
You may also combine them.

In this case, as shown in FIG. 6, the screen surface (screen surface layer 7) composed of a plurality of screen units 2 stacked one above the other is arranged so that the upper and lower screen units 2 The shape of the screen surface is devised.

(2) The fixtures for joining the screen units 2 together are not limited to the bolts 10 and nuts 11, but other appropriate fixtures such as clamping means can be used.

Although the screen unit according to the present invention has been described as being flat and not curved in the lateral direction, it is of course possible to curve the screen unit in the lateral direction and to form a circular shape by continuously connecting these units.

As is clear from the above description, the present invention has the following various effects.

■ The wide screen can be easily assembled on site and easily disassembled and removed.

■ By changing the number of screen units to be combined, a wide screen of the desired size can be easily obtained.

■ Excellent durability and can be used over and over again.

■ Since the screen surface is curved in the vertical direction so as to be concave toward the rear, there is no uneven brightness on the screen surface.

■ The screen unit itself can be easily transported.
