Description

Screen to resize screen {.}

The present invention relates to a screen that can be adjusted in size, and more particularly, to a screen that can be easily assembled and disassembled and resized to move and install a fixed one-piece-shaped screen.

There is a growing demand for homes and offices that require high-resolution resolutions and large screens, and the conventional roll screens have problems such as low reflection angles and image quality.

In addition, a conventional screen manufacturing method (Patent Registration No. 1996-0003039) first uses a sheet of 10-200 ° in which a surface sheet or surface of a reflective material is coated or deposited on aluminum or wheel with high elongation. Compression roller processes and surface coating processes known as thin films enable mass production in the form of foils or films in which the reflective material and surface state of the surface and the protective film 16 are uniformly formed. However, the thickness of the surface material is 10-200 ?? The reason is that 10 ?? or less is too thin, and if it does not extend to the spherical surface, the elongation is lost because the thickness is more than 200 ??.

The screen surface material produced in a uniform mass by the above process is pressurized by a spherical mold having the correct curvature and surface state to be described below, and the resin is laminated or foamed on the back surface to maintain the accuracy of the screen spherical curvature and the surface reflecting surface. As well as the uniformity as well as to maintain the screen spherical mass production is to be described in detail by the drawings.

First of all, in order to spherically screen the screen material mass produced by the above-described process, a spherical frame having a uniform spherical curvature and surface state is required.

A method of manufacturing a spherical frame, such as a line, and forming a hard plate such as a metal or plastic FRP having a thickness of 1-20 M / M to an approximation of a curvature to be obtained by partial partial pressing or forming by means of a press and a lower frame. do.

Since the molded hard plate has a rough surface, a non-uniform spherical surface, and a lot of pressure marks, as shown in FIG. To form a polishing surface.

After the polishing surface is completely cured as described above, as shown in FIG. 3C, the surface of the spherical mold is placed on the surface of the spherical mold in conjunction with the polishing plate with the curvature desired to be obtained.

In this case, when the hard plate is rotated by the rotating shaft, the surface of the polishing surface is polished by the abrasive, since the polishing plate placed on the polishing surface is also repeatedly moved left and right by the hard plate and the co-rotating rotating rod. Depending on the material of the polished surface, the inventors laminated it with Homica and used the Geumgangsa between 40-100 necks (目 = mesh) in 2-3 steps to obtain about 800 fine polished surfaces in 1 hour.

Therefore, when the surface of the polishing surface is roughly polished with the abrasive material between 40-100 necks, and then polished with a high abrasive material of 200 or more and 400 necks again, a polishing surface having a fine polishing surface having an accurate curvature is obtained within a short time. However, the polished surface is polished from 40 to 4000 necks. For 40 necks or less, the surface particle is very rough, so the surface of the screen surface material becomes rough. Because it is not hard. The hard plate of the polished surface thus completed is attached to the lower end of the spherical frame as shown in FIG. The reason for spherical polishing of the surface of the spherical mold as described above is that the surface state and the accuracy of the spherical surface of the screen surface material formed into the pressurized spherical surface are immediately determined by the spherical mold.

Next, an apparatus for manufacturing and pressing the screen using the spherical mold thus formed is required. In other words, the support frame is placed outside the spherical frame, and each press spring is extended, and the support frame moves upward and downward on the outward spherical frame polishing surface.

In addition, the upper side of the pressing frame is configured to be detachable from the press contact with the pressing stand, but the portion of the pressing frame and the supporting frame is formed in a mutually X shape, the stronger the screen surface material is pressed between the pressing frame and the supporting frame.

When the screen manufacturing pressurizing device inserts a flexible screen surface material in a foil state between the pressing frame and the supporting frame to an area larger than the required screen size and presses the pressing frame, the pressing frame pushes down the screen surface material and the supporting frame is a spring force of the support. Since it is moved downward while receiving elasticity, it is pressed into the spherical curvature of the screen surface material and the abrasive surface in the fixed state so that it is molded into a spherical shape and adheres to the polished surface.

In this way, the material is stretched by pressing, and the Homica mat or urethane resin is laminated and foamed onto the back surface of the screen surface material formed by the polishing surface to form a spherical support surface of the screen and then harden.

At this time, since the pressing frame and the spherical frame can be separated from the press by tying the clamping frame at each position, mass production of a uniform screen can be achieved if the spherical frame is provided in the pressure device as described above.

When the spherical holding surface of the screen is hardened by the above process, slowly loosening the fastening frame, the pressing frame and the supporting frame are separated by the spring elasticity of the support, and the screen front plate is completed. In combination with the aid, the screen is completed.

In the above case, the pressing frame, the supporting frame, and the spring structure associated with it have a purpose to strongly tighten the surface material so that the spherical frame itself moves up and down while the surface material is fixed. Do.

As described above, the screen quality has been improved and the reflection angle or better screen has been developed, but there are problems due to the storage location such as installation problems and the like due to the large size.

In order to solve the above problems, the present invention is to provide a screen that can be adjusted to the screen size to facilitate the assembly or disassembly installation by configuring the screen in each unit.

Another object of the present invention is to provide a screen that can be adjusted to one screen size so that the joint portion of each unit does not appear.

In order to achieve the above object, the present invention achieves the screen by combining the screen with each unit.

Hereinafter, a screen capable of adjusting the screen size of the present invention will be described in detail with reference to the accompanying drawings.
