JPS5812681B2 - Decorative display device made of optical fiber - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a decorative display device made of a novel optical fiber, and its purpose is to display jewelry, accessories, etc.
The object of this invention is to beautifully illuminate watches, cameras, and other large and small objects, thereby increasing the display effect, and is particularly effective as a display device for shop windows, showcases, exhibition items, etc.

Although many decorative devices using optical fibers have been proposed and put into practical use, the use of optical fibers in devices for lighting displays of other articles has never been done.

The present invention is a basket made by knitting, weaving or bonding optical fibers.
Formed into a dish, plate, or box-like object, all or part of one end surface of the optical fibers constituting these is fixed toward the center for illumination, and the other end surface is focused into a bundle to introduce light rays. The gist of this article is a decorative display device made of optical fiber, which is characterized by the following features:

The optical fiber mentioned above is made of an organic polymer or an inorganic glass, and a total reflection type fiber having a so-called core and sheath structure can be used.

Additionally, additional decorative effects can be achieved by coloring the optical fiber and damaging or removing part or all of the sheath.

For the purpose of increasing the decorative or reinforcing effect of the optical fiber, it is also possible to form an exhibition device using metal wires, resin rods, wood and bamboo, etc.

Optical fibers can be knitted, woven or bonded to create display devices of various shapes, such as baskets, shelves, etc. using bamboo crafts.
You can make bongs, prickly pears, boxes, etc. using the same method.

It can also be made manually using adhesive.

All or part of one end surface of the optical fibers forming these display devices is fixed to suitably face the display article placed in the center of the display device so as to produce the most decorative illumination effect.

This fixing can be done using heat, adhesive, etc., or physically by adjusting the structure of the display device.

In order to further improve the illumination effect of the exhibit, it is also effective to change the cutting direction of the end face of the optical fiber or to remove or damage the sheath of the optical fiber.

The light beam introduced to the bundle at the other end of the optical fiber is white light,
Colored light or a mixture thereof can be used, and the coloring of the light can also be changed using a rotating colored filter or the like.

EXAMPLES The present invention will be explained in more detail below with reference to Examples, but these are not intended to limit the scope of the present invention.

Example 1 A spherical basket as shown in FIG. 1 was made by weaving plastic optical fibers with a diameter of 1 mm using polymethyl methacrylate as the core and fluorine-containing polymer as the sheath in the same manner as bamboo crafts.

As shown in the partial vertical cross-sectional view of this cage in Figure 2, the number of optical fibers that make up the lower half of the cage is 2 times the total length.
It was cut to 1/2 the length and each end face 1 was bent horizontally and fixed to illuminate the center of the basket.

The remaining one-half of the fibers were used up to the top of the basket, cut at the top, bent each end face 2 downward and heat-set, and similarly illuminated the center of the basket.

The arrows in FIG. 2 indicate the passing direction of the light rays.

The other end surface 3 of the optical fiber was converged at the bottom, and the light was guided by a light source 4 through a rotating color filter 5.

Reference numeral 6 is an exhibition stand made of transparent acrylic resin square timber.

Example 2 A 0.5 mm diameter optical fiber with the same composition as in Example 1 was used, and a metal wire partially plated with silver was used for reinforcement to create a birdcage shape as shown in Figure 3. An exhibition device was created using the adhesive method.

This basket is made by cutting a small number of optical fiber bundles as they go up from the bottom to the top, as shown in the partial vertical front view of FIG. It was set by bending it towards the center.

The other end face 3 of the optical fiber bundle was aligned to form a bundle as shown in FIG. 3, and light was supplied from a light source 3.

The article suspended from the center of the birdcage by the hook 12 was beautifully illuminated by each end face.

Example 3 The same optical fibers used in Example 1 were knitted in the same manner as bamboo crafts to produce a dish-shaped display device as shown in FIG.

As shown in Fig. 6, which is a partial front view of this dish, some of the optical fibers are cut in the middle and fixed by bending the end face 13 toward the center while the optical fibers advance from the lower center of the dish to the periphery. The remaining optical fibers were set with the end faces 14 facing the center at the periphery.

The other end 3 of the fiber was focused to provide light from a light source 4.

It was found that the items placed on the stand 15 made of a black acrylic board were irradiated with light from the end faces of a large number of optical fibers, and had a remarkable display effect.
