Abstract

PURPOSE:To make a screen have a function sharing with the part of the constituting material of the wall surface of a building by exposing and fixing the end of an optical fiber in such a way that it almost aligns with the surface of a substrate part, and also suitable connecting the other end of the optical fiber to the light source. CONSTITUTION:In this screen, a substrate 1 is formed of a plate whose periphery is reinforced with a frame material 11, and the frame material 11 is made to constitute the part of the wall surface by assembling the frame material 11 inside the wall body 5 of the building or on this same wall body 5. The frame material 11 is made to constitute the part of the wall surface; therefore, it is desirable that the frame material is suitably ornamented in the frame state. And the opposite side surface to a surface where the substrate 1 of the frame material 11 is arranged especially does not need a surface plate, but in order that the optical fiber may not be damaged when the frame material 11 is treated as a product, it is closed by the sheet of the plywood 12, etc.,so that it is formed to be a drum-like plate, and the end where a connector 21 connected with a light source 3 is formed is made to project to either right and left or back from the plate, and the frame material 11 is made to be housed in a housing box 51, etc., formed at the part of a wall body 5 with the light source 3.

Description

Detailed Description of the Invention (Object of the Invention) The present invention relates to a flat surface for projecting an image from a screen, that is, a film projector, a video projector that magnifies and projects a video image, etc.
Particularly when not being used as a screen, g) the present invention aims to provide a screen having a novel structure in which the decorativeness of the face piece is improved.

(Prior Art) Japan, which has achieved economic development that is rare in the world, has benefited from advances in industrial technology and continues to be provided with various machines and appliances that are useful not only in production technology but also in daily life. Video equipment, which is at odds with each home, is one of the representative machines and appliances.More than 70% of homes are already equipped with video equipment, and many people are using it while at home. Now you can enjoy your video library.

Access to image culture in home life brought about by the spread of video equipment has become even more accessible, and as a result people have grown tired of the small images projected on 14-inch and 18-inch cathode ray tubes. Nowadays, the number of households enjoying images on large TV screens of 30 inches or more is increasing, and stores are crowded with large TVs from various manufacturers aiming to increase sales.

However, in the case of the current type of TV, the larger the TV, the larger the space it occupies.
It seems that the introduction of large TVs of about 50 inches is the limit.

Therefore, if we are to enjoy even more powerful images on a large screen in our country's housing situation, we will need a new means of imaging rather than the current type of television.

Video projectors are machines and devices that make this possible and are attracting attention as the next generation of video equipment, and are already on the market in some areas, showing signs of becoming popular products. According to this device, it is possible to project a fairly large image even in a relatively small space, as long as a screen is prepared, and it is possible to project a fairly large image even in a relatively small space. can be taken as a thing.

However, the projection of images by this video projector is not without its problems. In particular, in order to project a large-scale image, a correspondingly large screen is naturally necessary, and the screen must be a sharp vertical surface, usually white or gray, and is usually a wall of a building. This could be accomplished by attaching a separate screen to the wall or by forming the wall itself. In that case, it is of course impossible to place unnecessary accents or decorations within the area that will become the screen. In Tokyo, it is inevitable that the space will become extremely elongated and bland, and whether this happens in an ordinary house or a commercial building, it is certainly not a good thing. 9 This is expected to be the key to the extent to which video projectors will become contradictory as a means of enjoying large images.

In other words, we realized a new concept of a screen that is a space that fully functions as a part of the building even when it is not normally used as a screen, and that this does not interfere with its function as a screen at all. Unless this is done, it seems likely that video projectors will not become as popular as expected.

This invention was developed and completed based on the above viewpoint, and its configuration is as detailed below.

(Structure of the Invention) As clearly shown in the representative embodiments of the present invention shown in the drawings, the present invention basically has the following structure.

That is, the end of the optical fiber 2 is passed through the back surface of the substrate 1 made of a white or gray sheet or plate having a metallic painted surface or other high-luminance material surface a 1 according to a predetermined layout, and the end of the optical fiber 2 is The five optical fibers 2 are exposed and fixed so as to substantially coincide with the surface of the substrate 1, and the other ends of the five optical fibers 2 are appropriately connected to the light 'a3' to form a screen.

The material of the substrate 1 is not limited, and may be made of organic materials, inorganic materials, such as cloth, plastic, wood, wall covering, metal, stone, ceramics, or a laminated combination of these materials. It can be made of any material that has been produced, and must be finished in a white or gray color that does not interfere with the projection of images from video projectors (including film projectors and other devices). It is desirable that the surface be formed with a metallic painted surface or other high-brightness material finish to provide excellent projection effects.

Optical fiber 2 can be quartz optical fiber, but it is widely used as various display materials, sensors, communication materials, etc. because it has excellent mechanical properties, is relatively inexpensive, and is easy to connect with connectors. Plastic optical fibers (POF) are preferred. However, there is no particular restriction on the thickness, and it may be selected and used as appropriate depending on the content of the design to be expressed.

The optical fiber 2 has one end passed through the back surface of the substrate 1 and exposed to the front surface side, and the exposed end portion is formed so as to be in line with the surface of the substrate 1. 1 is fixed with Bond (trade name) or other suitable adhesive 4, as shown in the enlarged sectional view of the main part in FIG. 2, for example.

The light source 3 is an internal open part for sending out colored light for a desired display from one end of the so-called optical fiber 2 to the other end, and usually consists of a rotary color filter 31 and a light bulb arranged on the back side. However, it goes without saying that in addition to these known light sources, it is possible to employ any light source that suits the purpose.

Hereinafter, the configuration will be explained in more detail based on specific embodiments shown in the drawings.

(Example 1) The example shown in the perspective view of Figure 1 of the drawings is a screen that is incorporated into a part of the wall of a building (or can be adopted even when it is fixed to the surface of the wall). This is a typical example.

That is, the substrate 1 is surrounded by the frame material 11! ! The screen is formed from a board having a shape of i, and the frame material 11 is incorporated into or on the wall 5 of a building so as to constitute a part of the wall surface.

Since the frame material 11 constitutes a part of the wall surface, it is preferable that the frame material 11 be suitably decorated in the shape of a picture frame, as shown in the enlarged sectional view of the main part in FIG. Material 1
1 does not require a face plate on the opposite side to the side on which the substrate 1 is arranged, but when handling it as a product, the optical fiber 2
In order to prevent the light source from being damaged, the end of the connector 21 connected to the light source 3 is closed with a plywood plate 12 or the like as shown in the example shown in FIG. The parts protrude from the plate body either on the left or right side or on the back side.

As shown in FIG. 1, the light source 3 is housed together with the light source 3 in a storage box 51 formed on a part of the wall 5.

(Example 2) The following example is an example of a screen formed in a structure that has transportability, and as in a typical example shown in the enlarged cross-sectional view of the main part in FIG. 3, the substrate 1 is The back surface of the sheet, including the part where the optical fiber 2 is arranged, is covered and laminated with a spacing-maintaining backing material 13 such as a flocked sheet having a predetermined hair length, so that the entire part is flexible. The screen is formed into a certain mat-like material.

The spacing-maintaining lining material 13 is made of a material that is itself flexible, inside and outside of the flocked sheet having a predetermined nap length, and is designed to maintain the wiring spacing of the optical fibers 2 to the back of the substrate 1. Filling materials such as chemical lamination cod cotton, appropriate gel material, urethane foam powder, etc., are laminated or combined, or filled between the substrate 1 and the like are also included in the scope of filling.

(Operations and Effects) The screen of the present invention having the above-described configuration is provided on the surface of the substrate 1 that is to become the screen.

For example, the end of the optical fiber 2 may be fixed to the surface of the substrate 1 in an exposed manner in accordance with a layout aiming at a design effect such as a landscape painting shown schematically in FIG. Therefore, even if an image is projected onto the surface, the exposed end does not affect the projection of the image and can fulfill its original function as a so-called back screen. Moreover, there is no risk of dust etc. accumulating at the end of the optical fiber 2 during long-term use, and even when cleaning the surface of the substrate 1 periodically, cleaning is almost as smooth as cleaning a normal flat surface. It becomes possible.

When not using it as a screen, the light source 3
With the ON operation, the ends of the optical fibers 2 arranged in a predetermined layout on the smooth and bare board 1 will bloom with colorful flowers according to the layout, so it is suitable for use in large-scale images. An excellent feature is that even if a large area of white or gray space is permanently formed within or on the wall of a building, it will not give off a bland feeling as an equivalent space. There is a possibility that screens, which are indispensable for enjoying large-scale images, will be actively incorporated into buildings, and manufacturers are highly anticipating the future of video projectors. While this is expected to greatly contribute to the expansion of sales, it will also bring people closer to realizing the long-awaited home theater for people who enjoy video libraries in their homes. It is expected that this method will be advantageous in its adoption as an effective means of attracting customers by skillfully combining image expression and wall configuration in the spatial configuration of halls and other commercial buildings.

In particular, in the screen constructed as shown in Example 1, in which the frame material 11 is combined with the substrate l and the frame material 11 is recessed into a part of the wall 5 or attached on the wall 5, the color of the door, shoe cabinet, etc. Similar to building materials, pre-made screens of various sizes with several types of design patterns laid out in advance are used together with other construction materials during the building construction stage to achieve the design effect intended at the design stage. It has the feature that it can be incorporated and formed, and in the case of the example 2, it has good transportability and can be used as a wall construction material of buildings for various events, or as a display display for show windows, etc. It can exhibit excellent features such as being able to be adopted as a part of equipment.

As mentioned above, the screen invented by Kome changes the conventional concept of screens and is realized as a screen that has the function of being able to share a part of the wall structure of buildings. As architecture became more rigid, it became easier to introduce it into other commercial buildings, and screens were built in and formed in the required places in buildings in advance. In addition, in commercial buildings, it becomes possible to realize highly effective architectural projects in which the design effect of optical fibers and the design effect of images can be realized on the same wall surface.

It is expected that the screen of the present invention, which promotes sufficiency in terms of equipment, will greatly contribute to the expansion of sales of video projectors in the future.
