Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a decoration device used for indoor and outdoor decoration.

(Prior Art) In a conventional decoration device, as shown in FIG. 5, a large number of glass beads 2 are attached to the surface of a base sheet (for example, a polymer film such as polyester) 1 on which aluminum is vapor-deposited with an adhesive 3. There is a type in which a bead coat sheet 4 is formed by uniformly adhering it, and a decorative effect is exhibited by the reflection of the aluminum vapor deposition surface of the base sheet 1 and the light diffusion of the glass beads 2.

However, when such a decoration device is installed in a place where the light is weak or where the change in light is poor, the effect of its reflectivity is halved and the decorative property is poor.

As a decoration device capable of exhibiting decorativeness even in a place where the light is weak, Japanese Utility Model Laid-Open No. 60-162100 discloses an optical decoration in which an optical fiber is attached from the back side to the front side of a panel body equipped with a bead coat sheet. A device is disclosed.

(Problems to be solved by the invention) However, since the plurality of optical fibers are arranged in a scattered manner with respect to the panel surface and the light from the optical fibers is not diffused, the optical fibers are mounted by the spot light of the optical fibers. Only the part where there is light becomes bright, and uneven brightness occurs on the panel surface. Moreover, if a large light spot is obtained by bundling a large number of optical fibers or using a large-diameter fiber, the cost will increase.

The present invention has been made in view of the above-mentioned problems, and is intended to make it possible to exert a uniform and sufficient decorative effect over the entire panel surface even in a place where the light is weak or where the change in the light is small.

(Means for Solving the Problem) The technical means of the present invention for solving this technical problem comprises a bead coat sheet 9 in which a large number of beads 11 are mounted on the surface of a base sheet 10, and the bead coat sheet 9 is provided. In a decoration device including a bundle 17A of a plurality of optical fibers 17 inserted into the sheet 9 from the side of the base sheet 10, a plurality of light beams from the bundle of optical fibers 17A are arranged adjacent to the tip of the bundle 17A of the optical fibers 17 on the insertion side. The point is that a bead irradiation unit 18 for irradiating the beads 11 is provided.

(Operation) As shown in FIG. 1 or 3, part of the light from the insertion side tip of the optical fiber bundle 17A is directly emitted from the bead irradiating part 18 to the outside of the bead coat sheet 9, but part of the light is emitted. A plurality of adjacent beads 11 in contact with the bead irradiation unit 18 are irradiated. The light radiated on the beads 11 by the bead radiating unit 18 is diffused and reflected inside the beads 11 to bead-coated sheet 9
Released to the outside. Therefore, the light from the optical fiber bundle 17A is not a spot light according to the diameter of the optical fiber bundle 17A, but a spot light having a diameter larger than the diameter of the fiber bundle 17A as shown by the diagonal lines in FIGS. 2 and 4. And is discharged to the outside of the bead coat sheet 9.

This not only improves the decorativeness by providing the optical fiber, but when a plurality of optical fiber bundles are provided on the bead coat sheet in a scattered manner, the distance between the optical spots of the adjacent optical fiber bundles becomes small, and This leads to a reduction in uneven brightness on the decorative surface.

(Embodiment) Hereinafter, the present invention will be described with reference to the illustrated embodiment.
In FIG. 2 and FIG. 2, 8 is a fixing base plate, 9 is a bead coat sheet, and a large number of beads 11 are adhered to the surface of the base sheet 10. The base sheet 10 is formed by vapor-depositing aluminum on a polymer sheet (film) such as polyester, and the surface 10a of the base sheet 10 reflects light by vapor-depositing aluminum. The base sheet 10 is attached to the fixing base plate 8. Beads 11
Is preferably transparent, weather resistant, water resistant, and has been subjected to an adhesive treatment (for example, a silane coupling agent treatment). Also, a material having abrasion resistance can be used, and the material is glass or hard. Alternatively, soft plastic or the like is used to diffuse incident light and emit it. A large number of the beads 11 are evenly adhered to the surface 10a of the base sheet 10 by a permeable adhesive 12, and the beads 11 form a bead layer 13 on the surface 10a side of the base sheet 10.

Reference numeral 17 denotes an optical fiber, which is inserted into the fixing base plate 8 as an optical fiber bundle 17A in which a plurality of optical fibers 17 are bundled, and is also inserted into the bead coat sheet 9 from the side of the base sheet 10. The insertion end of the optical fiber 17 is the base sheet 10. It projects to the front surface 10a side and is located behind a plurality of beads 11. A bead irradiation unit 18 is provided at the insertion-side end of the optical fiber bundle 17A. The bead irradiating section 18 is formed by cutting the optical fiber bundle 17A into a tapered shape so that it can be inserted between a plurality of adjacent beads 11, and irradiates the beads 11 around the bead irradiating section 18.

3 and 4 show another embodiment in which an optical fiber bundle 17A obtained by bundling a plurality of optical fibers 17 is fixed to a base plate 8 for fixing.
By inserting the beads into the bead coat sheet 9 from the base sheet 10 side, projecting the insertion ends of the respective optical fibers 17 forward from between the beads 11, and fusing the insertion ends to integrally round them. The bead irradiation part 18 is formed. The bead irradiation unit 18 is an optical fiber 17
It is in contact with a plurality of adjacent beads 11 around A and irradiates these beads 11. Others are the same as the above-mentioned embodiment.

(Effect of the Invention) According to the present invention, since the bead irradiating part for irradiating the beads is formed at the tip of the optical fiber insertion part, the light of the bead irradiating part irradiates a plurality of adjacent beads and diffuses in the beads. It is reflected and becomes a large-diameter spot light, which is emitted to the outside. Therefore, the decorativeness can be effectively increased by the light from the optical fiber, as compared with the decorative device including the optical fiber without the bead irradiation unit.

Also, the bead irradiation unit processes the tip of the optical fiber bundle,
It can be easily formed by fusing.
