Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is directed to a novel manufacturing method for optical decorative bodies used for lighting windows, decorative windows, wall coverings, partitions, and various interior decoration items of buildings. This is related to.

<Prior art> Stained glass, a type of optical decoration that has been used for decorative windows and interior decoration of buildings since ancient times, is made by forming a number of pieces of glass (optical glass) colored with metal oxide into a predetermined pattern. and fit into the grooves of a frame called a lead frame with a U-shaped or H-shaped cross section as shown in FIG. 4, or surround the entire edge of each glass piece A with a tin foil tape B. Then, each of them is fixed and connected sequentially from the front and back as shown in Figure 4 by soldering C to form a single plate of a predetermined size.
It is used in stained glass windows in churches, and the beautiful and subtle decorative effects of transparent, colored glass, opaque, translucent, and colored glass that transmit light are respected.

<Problems to be Solved by the Invention> The production of conventional stained glass requires the aforementioned expensive copper tape or lead frame, which is a flexible material that can conform to the outer shape of each piece of glass.

Due to their material, they have a certain weight (1), a certain thickness,
Due to its width, it was not possible to configure the outer shape of the pattern into a thin line, or to freely mold it into the shape of a pond, so the pattern shape was limited.

In addition, skill is required for soldering techniques to secure and connect the copper tape and each piece of glass to which each piece of glass is fitted.
It is difficult to maintain the solder that makes up the joints uniformly and smoothly at a specified thickness, and the cost of soldering increases in addition to the raw material costs, and the finished product is heavy.1) Installation of windows etc. The labor costs were high, which was the cause of high product costs.As an industrial product, the raw materials are cheap, and many pieces of glass were sandwiched one by one in a frame, surrounded by copper tape, and soldered together, which was completely manual work. There has been a demand for the development of products and manufacturing methods that do not require much manufacturing effort.

<Means for Solving the Problems> The present invention uses a paper pattern of a predetermined shape, design, picture pattern, etc. and a photocurable resin, and the pattern is placed on top of the pattern of the paper pattern, etc., with the portions corresponding to the joints made transparent. A colored (glass) pattern cut into the same shape is placed, a photocurable resin is poured over the pattern, and a light beam having enough energy to cure the resin is irradiated, and the resulting product is obtained.

Effect> The photocuring resin poured onto the transparent joint portions between the colored glasses on the paper pattern by irradiation with the light rays hardens in a short time to form joints and connect the colored glasses.

<Example> The present invention will be explained in detail based on drawings of embodiments.

In Fig. 1, 1 is a light-transmitting glass plate called a light table, 2 is a paper pattern, which is made of a transparent film 3 with translucent properties, and as shown in Fig. 5, it transmits ultraviolet rays. Predetermined patterns 4a, 4b, . . . , 411 containing a non-transparent component or a dark-colored dye containing such a component are all provided through transparent joint portions 5. 3' is the peripheral joint part of the paper pattern 2. 6a, 6b.

... 6n is a predetermined single color or colored glass piece such as a shading pattern, and each pattern 4a is provided on the pattern paper in advance.
, 4b, . . . are cut slightly smaller than 4n. 7 is a tube for irradiating light such as ultraviolet light. In addition, the irradiation light is an electron beam,
It may also be radiation. In the production process using the above materials, the pattern 2 is placed on the upper surface of the transparent plate 1, and the corresponding glass pieces 6a, 6b, ... 6n are placed on top of it. , each of the patterns 4a has a predetermined thickness,
Spacers Sa', 8b...Sn made of a non-transparent material having the same shape as 4b...4n are attached to the respective patterns 4a, 4b...
4n, and furthermore, corresponding spacers S'a, S'b and S'b made of the same material as each spacer are placed on the upper surface of each glass piece.
...Place 8゛11, and then place the same pattern 2 as the pattern 2, facing each other, and place a transparent plate 1゛ as the weight of the whole 1.
That is, each piece of glass is sandwiched between the light-transmitting plates 1 and 1 by upper and lower spacers and paper patterns of the same shape. In the figure, reference numerals 9 and 9 are transparent thin sheets provided to prevent the resin liquid from adhering directly to each paper pattern. Pour the photocurable resin liquid 10 between the upper and lower sheets 9.9' which have been cured as described above. A leakage prevention frame is placed at a predetermined position outside the pattern to prevent the photocurable resin liquid from flowing out, and the photocurable resin liquid is poured into the frame. Thereafter, by irradiating ultraviolet rays from the lower surface of the light-transmitting plate 1 with a light irradiation tube 7, 7, etc., transparent joint parts 5, 3 can be created without hardening the resin in the colored parts of the paper pattern. hardens the resin in a few seconds. Incidentally, the perspiration of the photocurable resin liquid is caused by the upper spacer 8'a.
, S'b . . . may be immediately after S'11 is placed.

The photocurable resin liquid was required to be made of a material that quickly cures only the portion irradiated with light when irradiated with light, so an ultraviolet curable resin was used.

In addition, since the properties of the resin are as described above, each pattern 4 has the effect of blocking light with a light-shielding paint, and by making each colored glass slightly larger than the corresponding pattern, the pattern 4 can be The resin applied to the peripheral edge portion that protrudes from the joint hardens together with the resin at the joint, so that the cross section takes on an I-shaped, double-shaped, etc. shape.

The colored glass used may be transparent or translucent natural +1 fat (amber), natural stone (agate), ashes, or translucent colored plastic. Moreover, these opaque bodies may be used in combination.

A plurality of the paper patterns 2 are prepared based on one paper pattern, and the colored glass is cut in advance using one of the paper patterns.

Alternatively, the patterned paper pattern may be created by cutting the patterned portions of the paper pattern using a light-shielding silver iodide film, and pasting them onto a light-transmitting film with gaps between the joints. In addition, the outflow prevention frame is
When using a rectangular paper pattern, the paper is rectangular, but depending on the outline and external shape of the intended decorative object, a necessary shape such as a circle, an ellipse, an irregular shape, etc. can be created. The outer periphery of one decorative body regulated by the pattern is also formed into a sandwiched shape with a U-shaped cross section using a resin hardened edging formed by transparent joints in the outer periphery provided on the paper pattern 2. Alternatively, it may be edged with a conventional camel, copper film.

The above-mentioned photocurable resin cures within a few seconds of irradiation, and since the resin in the light-shielded area is in an uncured liquid state, it can be easily removed. There is no burn-in at all. The resin can also be freely colored in two colors in consideration of the decorative effect, and if the softness of the conventional lead cage is required, it may be possible to mix a resin with flexibility.

The products obtained by the above manufacturing method include each glass piece 6a,
6b, ... 6n are connected to each other by a connecting body 10a having an H-shaped cross section formed by curing the photocurable resin liquid 10,
The outer periphery of the optical decoration body 6 is composed of a peripheral joint portion 3 and an edge frame 10b having a U-shaped cross section which has been sweated and hardened. The optical decorative body 6 is lighter in weight than the conventional decorative body connected by lead cage or solder because the connecting body 10a and the frame 10b connecting the respective glass pieces are made of resin.

Also, since the manufacturing method is as described above, the joints 10a can have a free shape with the paper pattern compared to the conventional latch, so the finished connecting body 10a has wide parts, thin parts, and sharp points in terms of planar shape. The shapes and shapes are freely constructed, creating a variety of patterns. In addition, each plate-shaped decorative body can be three-dimensionally bonded with a photocurable resin using the same method as described above, and can be easily used for polygonal desk lamps, small cars, their pond folding screens, pillars, etc. It is a lightweight, easy-to-handle, safe, and workable decoration for interior decoration, walls, and window decorations.

As an embodiment of the pond according to the method of the present invention, the above manufacturing method may be carried out in two steps. That is, the transparent plate 1, paper pattern 2, irradiation tube 7, and spacer 8 are used as only the lower ones, and one side (lower side) of the glass piece is connected with a photocurable resin liquid, and then the glass piece is turned over so that the upper side is facing down. The pattern 2 may be turned over and produced in the same manner as described above (if the front and back sides are the same shape, it is left as is). Further, the glass piece (optical pattern piece) used may have a chamfered peripheral edge.

<Effects of the Invention> The optical decorative body of the present invention is lighter than conventional products, and can be easily attached to windows or walls even if it is a large one, making it easier to manufacture various three-dimensional decorative items. Further, according to the manufacturing method of the present invention, optical pattern pieces constituting the pattern are irradiated with light using a photosensitive film pattern, a light-transmitting plate, a light irradiation means, and a photocurable resin, thereby forming joints according to the pattern. All of these are constructed once, and at the same time, a board with interconnected edges of each pattern piece is constructed in a short time.

Therefore, since it does not require any skill, anyone can do it, it can be easily manufactured without any problems, and the workability is good. In addition, expensive lead cages and copper foil tapes are not required, and it is easy to create joints that cannot be constructed with such tapes. Can be molded with resin. Moreover, it is lightweight, and since the resin is cured on a smooth transparent plate, the joints are uniformly smooth on the surface and the finish is beautiful.

Furthermore, the connecting force of each pattern piece by the joints is completed at once by sweating the fat and irradiating the light, so the time required for the process is extremely shortened, and the product cost can be reduced.
