Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a lighting door in which various pattern figures are formed on doors at various places and light is emitted from the inside of the door body to reveal a glitter pattern. It is a thing.

[Prior Art] Conventionally, as a device in which a pattern figure is formed on a door and light is emitted from the inside, for example, as seen in Japanese Utility Model Publication No. 50-23041, a transparent plate is stretched on the surface to form a back plate. There has been proposed an illumination door in which a space having a space is provided to form various graphic patterns, and an illumination lamp is attached to the interior.

[Problems to be solved by the device]

However, since this conventional lighting door is provided with an illuminating lamp inside each of the pattern figures and the like defined between the gaps between the front and back plates, it is necessary to separate it from other pattern figures. In addition, an illuminating lamp must be provided inside each of the defined pattern figures. And
Since each pattern figure is simply illuminated by this illuminating lamp, there is a drawback that only uniformized patterns can be revealed.

The present invention has been made for the purpose of eliminating the above-mentioned drawbacks of the related art by utilizing an optical fiber and displaying an arbitrary bright pattern.

[Means for Solving the Problems]

As a concrete means for achieving the above-mentioned object, the present invention forms an arbitrary pattern figure by a translucent member on at least one of the front and back plates of the door body, and an optical fiber according to the shape of the pattern figure is formed. Arrange each free end of the group,
A light receiving portion is formed by converging the base end side of the optical fiber group, and the light receiving portion is connected to a light source device built in the door body, and a light pattern is generated by emitting light from the free end portion of the optical fiber group. The present invention proposes a lighting door characterized by being configured as shown.

[Action]

By the above means, the free end portion of the optical fiber arranged according to the shape of the pattern figure formed on the door body emits light,
Appear a desired glitter pattern.

〔Example〕

 Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a front view of a lighting door according to the present invention, and FIG. 2 is a sectional view of the same.

The door frame 2 and the front plate 3 and the back plate 4 constitute a door body 1, and an arbitrary pattern 5 is formed on the front plate 3 by a translucent member. Then, the respective free ends of the optical fiber group 6 are closely arranged according to the shape of the pattern figure 5.
The optical fiber group 6 is divided into a required number of blocks 6a, 6b, 6c, 6d according to colors in the pattern 5, and each block is focused to form a light receiving portion 7 on the base end side. In, a light source device 9 such as a laser light emitter is connected via an optical fiber distributor 8. As shown in FIG. 3, a light emitting diode 9a which emits red light, green light, yellow light, etc. by a compound semiconductor is used as the laser light emitter, and the light receiving part 7 of the optical fiber group 6 is contacted with this. From the free end of the optical fiber group 6 to the blocks 6a, 6b,
6c and 6d have different bright patterns. The optical fiber distributor 8 connected to the light source device 9 is controlled by known means already applied in various fields so that the color of each block can be changed and blinked with time.

A conventional light source lamp may be used as the light source device 9. In this case, the color of each block of the optical fiber group 6 is such that the light source lamp is provided with a filter of an arbitrary combination of colors, and conversely, the light source lamp is set to white light and the light transmissive member of the front plate 3 of the door body 1 is used. This can be realized by coloring the patterned figure 5 itself.

In addition, in this example, the case where the arbitrary pattern figure 5 made of the translucent member is formed on the front plate 3 of the door body 1 is shown. It doesn't matter.

[Effect of device]

According to the lighting door of the present invention having the above-described structure, an arbitrary pattern figure is formed by a translucent member on at least one of the front and back plates of the door body, and each optical fiber group is formed according to the shape of the pattern figure. Since the free end of is arranged and the free end is made to emit light so as to reveal the glitter pattern,
It is remarkably beautiful as compared with the monotonous decorative effect of the prior art, and is suitable as a decorative door for indoors and outdoors, such as restaurants and restaurants.

Since the lighting door of the present invention has a structure in which the light source device for emitting light of the optical fiber group is built in the door body, no special work is required for the door frame and workability is good.

[Brief description of drawings]

Each of the drawings shows an embodiment of the present invention. FIG. 1 is a front view of a lighting door, FIG. 2 is a sectional view of the same, and FIG. 3 shows a contact state between a light source device and a light receiving portion of an optical fiber group. It is sectional drawing shown. 1 …… door body 2 …… door frame 3 …… front plate 4 …… back plate 5 …… pattern figure, 6 …… optical fiber group 6a, 6b, 6c, 6d …… pattern figure block 7 …… Light receiving part, 8 ...
