Description

DETAILED DESCRIPTION OF THE INVENTION The present invention mainly relates to a rotary illumination display device that can be suitably used as an advertising medium.

At present, all kinds of media are used for advertisements, letters, figures, etc.
It is most desirable to use symbols or other displays dynamically to appeal to viewers effectively and economically. One commonly seen device is a rotating illumination display device that can be used as a signboard for barber shops. This is a structure in which a shaft is provided at the center of an internal rotating drum to rotate it, and a plurality of fluorescent lamps are provided inside the rotating drum to illuminate it. Therefore, since a rotating drum requires a rotation radius from the shaft to the fluorescent lamp, there is a limit to miniaturization, and there is also a limit to weight reduction due to the shaft and bearing structure, and it is not economical. had no choice but to become expensive. Other rotary display devices have similar drawbacks, and none have been able to satisfy both economic efficiency and advertising effectiveness.

As shown in Japanese Utility Model Publications No. 3-10983 and No. 13-10132, the disadvantages of the above-mentioned shaft and bearing structure have been solved by providing a bearing hole in the colored drum and inserting a fluorescent lamp into the drum. There is a rotary illumination display device that rotates a colored drum around a light lamp. According to these methods, it is necessary to attach a rotational drive gear to the coloring drum via a mounting shaft, which requires extra space in the direction of the drum axis for the mounting shaft and increases the number of parts. However, there were still limits to the miniaturization and weight reduction of devices.

Furthermore, as shown in Japanese Utility Model Publication No. 29-14126, there is a device in which a driven gear that is rotationally driven is provided on a support disk. According to this, although the driven gear itself constitutes the support disk, since it is not structured around the fluorescent lamp, it is necessary to reduce the weight of the support disk itself, the bearing structure with the fluorescent lamp, and the load on the fluorescent lamp. etc. are not considered at all.

The present invention was developed in view of the above-mentioned circumstances, and is a system in which a colored drum with bearing holes is rotated around a rod-shaped fluorescent lamp or the like serving as a light source. The main purpose is to reduce the weight of the support disk itself and to make the bearing hole structure a light-load structure. DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a rotary illumination display device according to the present invention will be described below with reference to the drawings.

Figures 1 to 3 of the drawings show a horizontal type implementation under the name of rotary light box. Figure 1 is an exploded perspective view of the rotary light box, Figure 2 is a partially cutaway plan view of the rotary light box, and The figure is a sectional view taken along the - line in FIG. 2.

The substrate 1 has leg portions 1a at its lower portion, and a lid 2 is removably placed on its upper portion. This lid body 2 is formed into a box shape from a light-shielding material and is screwed with a mounting screw 4 inserted into a long hole 3 bored in the substrate 1. Supports 5a and 5b are erected facing each other on the substrate 1 located inside the lid 2, and a pair of sockets 6a and 6b are provided with mounting screws at the tops of the opposing surfaces of these supports 5a and 5b. 7, respectively. These sockets 6a, 6b have caps 8a, 8 at both ends of a fluorescent lamp 8 as a rod-shaped light source.
By fitting b, the fluorescent lamp 8 is attached to the substrate 1.
It is installed horizontally at a distance from the

A cylindrical colored drum 9 slightly shorter than the length of the fluorescent lamp 8 is arranged around the rod-shaped outer periphery of the fluorescent lamp 8. The coloring drum 9 includes a cylindrical drum body 10 and support disks 11a and 11b fixed to both ends of the drum body 10. This drum body 10 is made by applying translucent colors, for example, red R, blue B, and lateral Y, to a transparent synthetic resin thin plate by silk screen printing, and the circumferential grooves 11a' of the support disks 11a, 11b, 11b' to form parallel belt-shaped colored regions in the circumferential direction. The support disks 11a and 11b are heat-resistant synthetic resin molded products, and bearing holes 12a and 12b having a diameter slightly larger than the tube diameter of the fluorescent lamp 8 are provided in the center thereof. The bearing holes 12a, 12b are molded inside wide bearing portions 12c, 12c that protrude toward the inside of the cylinder. By inserting the fluorescent lamp 8 from one of these bearing holes 12a, 12b to the other, the coloring drum 9 is rotatably supported around the fluorescent lamp 8. A plurality of air vent holes 13 are bored around the bearing holes 12a, 12b.
Further, a large-diameter driven gear 21 is carved on the outer peripheral surface of the support disks 11a and 11b.

Further, a drive motor 14, a glow lamp 15, and a transformer 16 are fixed to the substrate 1, and a connection between the drive motor 14, the glow lamp 15, the transformer 16, and the sockets 6a and 6b is provided from the outside via a bushing 17. Electricity is supplied by a power cord 18 introduced onto the board 1. A small-diameter drive gear 20 is fixed to the output shaft 19 of the drive motor 14, and this drive gear 20 is engaged with a driven gear 21 of the coloring drum 9. Both gears 20, 2
1 is positioned by inserting a ring-shaped positioning spacer 23 into the other end of the fluorescent lamp 8. Furthermore, a display section 22 such as translucent characters is formed on the front surface of the lid body 2, and the display section 22 includes a fluorescent lamp 8 that has passed through the circumferential surface of the colored drum 9.
irradiated light is transmitted. The outer surface 2 of this display section 22
2a is formed into a wavy curved surface that makes the refractive index of transmitted light different. This wavy curved surface is provided so as to be parallel to the band shape of the colored area, and is roughly divided into upward, forward, and downward irradiation light beams and color changes.

To explain the operation of the above embodiment, if the fluorescent lamp 8 and the drive motor 14 are turned on after inserting a power plug (not shown) into an outlet, the fluorescent lamp 8 lights up and at the same time the drive motor 14 starts driving. The rotation of the coloring drum 9 is transmitted via the driving gear 20 and the driven gear 21. colored drum 9
is the bearing hole 1 with the rod-shaped part of the fluorescent lamp 8 as the supporting shaft.
It will rotate from 2a and 12b. In this case, the irradiation light from the fluorescent lamp 8 passes through the circumferential surface of the coloring drum 9 and irradiates the outside from the display section 22 of the lid body 2. To explain in detail, the display section 22 displays the coloring drum 9.
Among the colored areas of red R, blue B, and yellow Y, the colored area is colored in a straight line, and the coloring changes according to the rotation of the colored area as the coloring drum 9 rotates. Moreover, depending on the refractive index of the wavy curved surface, the irradiation angle will change with color change. Further, the display portion can be formed on a curved surface other than a wavy curved surface. Characters, figures, symbols, etc. can be formed on the display section as desired.

According to this embodiment, since the display part such as characters can be irradiated in a colored state that changes sequentially, it can arouse surprise in the viewer and has high practical value as a media product for advertising. .

FIG. 4 is a front view showing another embodiment of the rotary irradiation device. In the figure, the same reference numerals indicate equivalent parts, and 24 is a spacer that supports the vertically arranged coloring drum 9. In this embodiment, a fluorescent lamp 8 is arranged vertically through upper and lower sockets 6a and 6b, and a coloring drum 9 is inserted vertically with this vertical fluorescent lamp 8 as the axis. Driven gear 2
1 is driven by a drive gear 20 of a drive motor 14. In this case, since the coloring drum 9 is lightweight and its load is supported by the spacer 24, good rotational driving is possible. Although not shown, a thrust bearing may be interposed between the spacer 24 and the lower end of the coloring drum 9, or a thrust bearing may be interposed instead of the spacer 24. According to this embodiment, a vertical rotary irradiation display device can be configured, and for example, the coloring area can be formed in a diagonal striped pattern of red R, white W, and blue B by covering the outside of the coloring drum 9 with a translucent container. For example, it can be implemented as a signboard for a barber shop.

As explained above, according to the present invention, the following effects could be obtained.

Since the bearing hole of the support disk is made to protrude toward the inside of the cylinder to form a wide bearing part, a large contact area with the rod-shaped light source can be ensured, and concentrated stress on the rod-shaped light source when the coloring drum rotates can be dispersed. was completed.

For this reason, the support disk can be made thin, and when combined with the provision of multiple air vent holes around the bearing hole and the use of synthetic resin as material, the coloring drum can be made the most lightweight. was completed.

By reducing the weight of the coloring drum and the bearing structure of the wide bearing part, it is possible to relieve the load on the rod-shaped light source when the coloring drum rotates, and the shaft can be moved without damaging the rod-shaped light source as in the conventional case. It was possible to put it into practical use as
