Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a decorative device using a bead coated sheet formed by laminating a transparent bead layer on the surface of a transparent sheet. This decorative device is used, for example, in internally illuminated interior lighting and internally illuminated store signboards.

(Prior technology) Transparent sheets with various patterns printed on them (Colton,
(vinyl chloride film, PET, etc.).

It is already known that a bead-coated sheet made of laminated transparent bead layers has been devised, and that when light is shined from the back side of this bead-coated sheet, the pattern becomes visible and can exert a remarkable decorative effect. Yes (for example, Jitsugan Sho 6l-
80801).

(Problem to be solved by the invention) However, if the light is simply applied from the back side of the bead coated sheet, the incident light on the transparent bead layer will be in a fixed direction, and the light transmitted through the transparent bead layer will be diffused in the same direction. There was no change, and as a result, the raised pattern remained fixed, and there was no dynamic change in the pattern (in this respect, there was a problem that the decorative effect was lacking).

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to provide a decorative device that can dynamically change a pattern and exhibit even more decorative effects.

(Means for Solving the Problem) The technical means of the present invention for solving this technical problem consists of a bead coated sheet l formed by laminating a transparent bead layer 4 on the surface of a transparent sheet 2, In a decorative device equipped with a light 'rj, 15 that illuminates the sheet 1 from the back side, a diffuser 8 that transmits and diffuses light in a scattering manner is provided so as to overlap the back surface of the bead coated sheet 1, and the diffuser A drive means is provided for moving the bead-coated sheet 8 relative to the bead-coated sheet 1 in the direction of the surface of the sheet.

(Function) Light #15 passes through the diffuser 8 to the bead coated sheet 1.
When illuminated from the back side, the pattern on the bead coated sheet L appears to stand out. Furthermore, since the diffuser 8 moves relative to the bead-coated sheet 1 in the sheet surface direction, the direction of light passing through the transparent bead layer 4 of the bead-coated sheet 1 changes finely, causing the shine of the bead layer 4 to change. The pattern changes in minute units, creating a pattern full of dynamic changes.

(Example) Hereinafter, the present invention will be explained according to the illustrated example.
In the figure and FIG. 2, 1 is a bead coated sheet, and as shown in FIG. 3, a transparent bead layer 4 is integrally laminated and fixed on the surface of a flexible transparent sheet 2 via an adhesive layer 3. A transparent cover coat layer 5 is formed on the surface of the transparent bead layer 4. The bead-coated sheet 1 is wound into a cylindrical shape, and annular press members 6.7 are fitted onto both upper and lower ends of the bead-coated sheet 1, so that the bead-coated sheet 1 is maintained in a cylindrical shape.

Transparent sheet 2 of the bead coated sheet 1 has a thickness of 20 to 30
00 μm, preferably 100 to 2000 μm, and has properties such as water resistance, weather resistance, and corrosion resistance, and has a pattern printed or colored depending on the purpose.
In some cases, it is preferable to use adhesive-treated materials.

Plastic sheets such as polyvinyl chloride, polyethylene, polypropylene, polyester, acrylic, and polycarbonate are usually used as materials, but natural fibers such as cotton, linen, rayon, nylon, polyester, and acrylic, chemical fibers, or synthetic fibers are also used. As materials, Akebono cloth or non-woven fabric, leather, paper such as synthetic or natural paper, metal foil, etc. are selected and used depending on the purpose. In particular, polyvinyl chloride sheets are suitable because they are inexpensive, their flexibility can be easily adjusted by adjusting the content of plasticizer, and they can be easily printed and colored.

The adhesive for the adhesive layer 3 is flexible, such as urethane-based, acrylic-based, epoxy-based, fluorine-based, silicone-based, etc., and has properties such as transparency, water resistance, weather resistance, and corrosion resistance. It is preferable to use a low-temperature curing type that has low shrinkage properties. Especially non-shrinkable epoxy resin or vinyl acetate,
Aqueous emulsion type resins such as acrylic esters are preferred. When these resin adhesives are used, there is almost no shrinkage of the transparent sheet 2, so the adhesion of the transparent beads can be significantly improved, missing beads can be eliminated, and the quality of the finished surface can be improved. You can improve your performance. Furthermore, since these resin adhesives do not contain any organic solvent, even if an inexpensive and suitable vinyl chloride sheet is used as the transparent sheet 2, the organic solvent will not migrate to the plasticizer in the sheet. No sheet swelling occurs, and bead-coated sheets of good quality can be easily obtained at low cost.

The adhesive layer 3 is formed by uniformly applying the adhesive to the surface of the transparent sheet 2 by appropriate means, such as a roll coater or spray, depending on the bead size, to a thickness that does not bury the beads in the adhesive layer. Ru. At this time adhesive layer 3
If the beads are buried in the bead, the decorative and functional effects due to the size and transparency of the beads cannot be expected, so the thickness of the adhesive layer 3 is usually preferably less than the bead particle diameter A.

In addition, when forming an adhesive layer using a water-based emulsion type resin, the adhesive can be diluted with water, making the application process extremely easy, reducing manufacturing costs by reducing manufacturing loss and improving workability. can be achieved.

The cover coat agent of the cover coat layer 5 coated on the surface of the bead layer 4 is made of the same material as the adhesive of the adhesive layer 3 described above. The thickness of the cover coat layer 5 is set to an appropriate thickness of 17 mm (preferably 500 pts or less) so as not to erase the uneven surface of the bead layer 4.

Note that the adhesive and cover coat agent forming the adhesive layer 3 and the cover coat layer 5 may be based on ultraviolet curing reactive synthetic resin depending on the type of flexible sheet.

The beads forming the bead layer 4 have transparency, weather resistance, and water resistance, and are subjected to adhesive treatment (for example, silane coupling agent treatment).
It is preferable to use a material having abrasion resistance, and a material having wear resistance can also be used, and the material used may be glass, hard or soft plastic, etc. Examples of the camping agent used in the silane coupling agent treatment include aminosilane, glyoxide silane, and acrylic silane, among which acrylic silane treatment is preferred. In addition, beads with a diameter of about 30 to 5000 μl are used;
2500 μm is preferred.

The bead layer 4 is formed by uniformly scattering beads on the uncured adhesive layer applied to the transparent sheet 2, applying appropriate pressure to bring them into close contact, and then drying and curing the adhesive layer.

As a dry curing method, use low temperature or heating as necessary,
Alternatively, it is cured by projecting ultraviolet light (including electron beams). The heating method can use an infrared heater, an electric oven, or the like. Flexible sheet with high heat shrinkage,
For example, for a soft PVC sheet, the temperature may be adjusted as necessary by water cooling or air cooling, or the sheet may be dried at room temperature or cured at 80° C. or lower using a low temperature curing resin.

The cover coat layer 5 is formed by applying or spraying a cover coat agent onto the bead layer 4 by an appropriate means after the adhesive layer 3 is cured, and then drying and curing it in the same manner as described above.
