Description

[Detailed description of the invention] Industrial applications The present invention relates to illuminated signboards.

Conventional configurations and their problems Generally, illuminated signboards have a light source placed inside the signboard body.
Many displays are displayed by illuminating the front and rear display panels, and because they lack a dynamic element, it is difficult to display effectively. From such a thing,
Devices equipped with a rotating plate inside the main body and displaying dynamic images on a display panel are now being used, but these devices are not very interesting because they display only the display panel.

On the other hand, there are some that arrange a large number of light emitters on the edge of the sign body and make them blink, but this requires a large number of lamps or light emitting diodes.
It also requires a control switch, which is economically undesirable.

Normally, in order to make the edges of the sign body shine brightly, the members of the sign body are made of a transparent material such as acrylic resin, and the light from the light emitting body provided inside the sign body is guided by the transparent material. In addition, emitting light at the edge portion is economical from a component standpoint, and is also practical as a simple means. However, in the case where the edges of the sign body are made to emit light, it is easy to make only the front part emit light, but it is difficult to make the edge parts on both sides emit light using a single light source.

Purpose of the Invention In view of the above problems, the present invention illuminates both the front and rear display panels with a single light source, and
The purpose of this is to create a dynamic light ring on the edges of both the front and rear surfaces to create an interesting display.

Structure of the Invention In order to achieve the above object, the present invention has an annular wall that is stacked on top of each other and has a circular through hole in the center and an annular wall surrounding the through hole on the outer surface, and further has an annular wall at the outer end. Two translucent base plates having inclined reflective surfaces, a driving motor placed in the through hole, an annular fluorescent lamp also placed in the through hole, and the driving motor. a rotary body which is arranged to be rotated and has a body portion having a pattern or the like attached thereto to change the transmitted light, and which is positioned between the end face of the annular fluorescent lamp and the through hole; and each of the light transmitting elements. two front and rear display panels whose outer ends are in contact with the annular wall of the base plate; a presser frame which is fitted onto the outer periphery of each of the annular walls and holds down both of the display panels; It is composed of a frame member made by sandwiching the outer ends of two translucent base plates. With this structure, it is possible to illuminate both the front and rear display panels with a single light source, and also A dynamic light ring appears on the edge portions of both sides, allowing effective display.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view showing an example of a signboard embodying the present invention, which consists of an illuminated signboard part 1 and a stand part 2. Since the illuminated signboard section 1 uses a fluorescent discharge tube as a light source, a ballast 3 is attached to the outside. The reason why the ballast 3 is mounted outside is due to the space inside the illuminated signboard section 1 and the ballast heat radiation.

The illuminated signboard section 1 is constructed as shown in FIG. That is, flat transparent base plates 4 and 4' made of acrylic resin, glass, etc. are stacked on top of each other, and these serve as the base. The translucent base plates 4, 4' have relatively large circular through holes 5, 5' in the center for arranging the light source section and the rotation drive section, and the edges of the through holes 5, 5' The surface is the light-receiving surface. Further, the translucent base plates 4, 4' are integrally provided with annular walls 6, 6' protruding from their outer surfaces to surround the through holes 5, 5' for holding the display panel, and further, Ribs 8, 8' are provided on the outer peripheries of the annular walls 6, 6' to form grooves 7, 7' between the annular walls 6, 6'. The edge portions of the translucent base plates 4, 4' are formed as follows. In other words, the light reflecting surfaces 9, 9' are provided at the outer peripheral end portions and are inclined with respect to the axis of the light introduced through the through holes 5, 5'.
Projections 10 and 10' are provided on the outer surface portions corresponding to the light reflecting surfaces 9 and 9', and these portions serve as light ring revealing portions. A gap 11 is formed between the outer peripheral ends of the light-transmitting base plates 4, 4' by the inclined light reflecting surfaces 9, 9'. Further, a frame member 12 made of aluminum or the like is attached to the outer peripheral edge of the translucent base plates 4, 4'. This frame member 12 is a member 12 that is divided into left and right halves in advance.
a and 12b, each having a U-shaped cross section, the outer peripheral edges of the translucent base plates 4 and 4' are clamped, and both ends are connected by a connecting member 13 (see Fig. 6). . This connecting member 13 is connected to a gap 11 formed between the outer peripheral edges of the translucent base plates 4 and 4'.
It is designed to fit inside. Further, as shown in FIG. 2, a mounting member 14 such as a stand is attached to the frame member 12.
The end of the screw 15 and the nut 16 also fit into the gap 11.

Incidentally, ribs 17, 17' are provided on the inner side of the frame member 12 to protrude from the inner side of the frame member 12 in order to more securely prevent the outer peripheral edges of the translucent base plates 4, 4' from being clamped. Also,
In order to effectively provide a plurality of light ring revealing parts on the translucent base plates 4, 4', the translucent base plates 4, 4'
Auxiliary reflecting surfaces 18, 18' are formed by V-shaped grooves on the back surface near the outer edge of the mirror 4'. The auxiliary reflecting surfaces 18, 18' also reflect the guided light and project it onto the outer surface. These structures are clearly visible in FIG.

A transparent hole 5 in the center of the transparent base plate 4, 4'
5' includes a drive motor 19 and a light source lamp 20.
and a rotating body 21 are arranged. The drive motor 1
9 has a speed reducer, and is attached to and held by the holding plate 22. The ends of the holding plate 22 are fixed to the translucent base plates 4, 4' by screws 23. At this time, the screw 23 is attached to the transparent base plate 4, 4'.
Make mutual connections. In this embodiment, the light source lamp 20 uses an annular fluorescent discharge lamp.
This light source lamp 20 is also fixed to the holding plate 22 by a suitable clamp member (not shown). Rotating body 2
1 is rotatably provided with its center connected to the output shaft of the drive motor 19, and its peripheral body 24 at the outer end is connected to a light source lamp 20, a translucent base plate 4,
4' is located between the end faces of the through holes 5, 5'. The circumferential trunk portion 24 is provided with a suitable discontinuous pattern or coloring. Therefore, the light from the light source lamp 20 is applied to the end faces of the through holes 5, 5' of the translucent base plates 4, 4' via the circumferential body 24, and discontinuous light is provided by the rotation of the circumferential body 24. It turns out. Incidentally, a glow lamp 25 serving as a starter for the fluorescent lamp is attached to a holding plate 22 (see FIG. 5).

The outer peripheral ends of thin flat display panels 26, 26' are placed on annular walls 6, 6' provided on the outer surfaces of the translucent base plates 4, 4' to surround the through holes 5, 5'. The inner drive motor 19 and the like are sealed. The display panels 26, 26' are held down by annular holding frames 27, 27'. The presser frames 27, 27' have presser edges 28, 2 at their leading edges.
8', and is fitted onto the outer periphery of the annular walls 6, 6', and the proximal end is connected to the annular walls 6, 6' and the ribs 8, 8'.
It is inserted between grooves 7 and 7' formed between grooves 8'. The base end portions of the holding frames 27, 27' are provided with grooves 7,
It is in pressure contact with seal rings 29, 29' made of rubber or the like provided at 7'. and an annular wall 6,
6' by screws 30, 30'.

The illuminated signboard of the present invention is constructed as described above, and when in use, the light source lamp 20 is lit and the drive motor 19 is driven to rotate the rotating body 21, but the light from the light source lamp 20 is directly emitted from both sides. display panel 2
6, 26' are illuminated to produce the desired display.
On the other hand, the light emitted from the side of the light source lamp 20 is first applied to the end surfaces of the two translucent base plates 4 and 4' via the translucent peripheral body 24 of the rotating body 21. At this time, since the circumferential body portion 24 has an intermittent pattern or a striped pattern so as to change the light, the light given to the translucent base plates 4, 4' becomes intermittent light. The light that has entered the translucent base plates 4, 4' travels linearly toward the outer peripheral edge, but is reflected by the reflective surfaces 9, 9' that are inclined near the edges, and the light enters the translucent base plates 4, 4. The outer surface of the end of ′ is emitted. That is,
An annular discontinuous light ring is made to appear at the outer edge of each outer surface of the translucent base plates 4 and 4', and since this is dynamic due to the rotation of the rotating body 21, it gives a strong visual impression. . The auxiliary reflecting surfaces 18, 18' also reflect light in a similar manner, and a discontinuous light ring with a small width appears on the surface of the transparent base plates 4, 4'. These discontinuous light rings are effective because they appear on both the front and rear sides of the illuminated signboard. In guiding the light through the translucent base plates 4, 4', the frame member that clamps the outer peripheral ends of the translucent base plates 4, 4' not only serves to fix the light but also to block the light and prevent the discontinuity. Contributes to the appearance of the halo. Note that protruding portions 10 and 1 are provided at the peripheral ends of the translucent base plates 4 and 4'.
If 0' is provided, it has the effect of clarifying the width of the light ring.

If the light source lamp 20 is an annular fluorescent lamp as shown in the figure, the driving motor can be placed in the center thereof, which is effective in terms of space. In addition, since the transparent holes 5, 5' of the transparent base plates 4, 4' are made larger, the end faces of the transparent base plates 4, 4', that is, the outer side of the transparent base plates 4, 4' are lower than the light receiving surface. Attenuation of light can be prevented by reducing the distance to the end.

Display panels 26, 26' and holding frames 27, 2
7' makes the illuminated signboard part look like a case and has a sealed structure to prevent rainwater from entering. in this case,
The sealing rings 29, 29' assist in the waterproofing function.
Therefore, it is effective for outdoor use. When using a fluorescent lamp as a light source, ballast 3
However, if this ballast 3 is installed inside the illuminated signboard 1, heat dissipation will be poor and a large capacity will be required, so it is preferable to mount the ballast outside as in this embodiment. .

Although the illuminated signboard part is polygonal in the above embodiment, it is not limited to this shape, and may be circular, for example. Further, the light-transmitting base plate may be a glass plate, but synthetic resin such as acrylic resin is preferable from the viewpoint of workability and light weight.

Effects of the Invention As explained above, the illuminated signboard of the present invention is capable of clearly displaying a desired display by illuminating both display panels with a single light source lamp.
Light is introduced from the hole edges of the two translucent base plates, and the outer surface of each translucent base plate is illuminated in an annular shape at the outer circumferential end of each translucent base plate, and the illumination light is changed by the circumferential body of the rotating body. Therefore, it has a great visual effect.

In particular, the drive motor, rotating body, and light source lamp are arranged within the hole in the translucent base plate, which reduces the thickness of the illuminated signboard, which is advantageous as a double-sided illumination type, and the light source lamp is also an annular fluorescent lamp. By doing so, it is possible to increase the size of the through-hole in the light-transmitting base plate, reduce the distance from the light receiving section to the end display section, and reduce light loss. In addition, the frame that sandwiches the outer edges of the two translucent base plates is
Since the end portion of the translucent base plate can act as a light shield, a special light shield is not required. Furthermore, since the display panel is held down by a holding frame to seal the inside, there is no problem with rainwater entering even when used outdoors, and the holding frame is placed on the outer surface of the transparent base plate. Since it is fitted and fixed to the protruding wall that is integrally provided, the waterproof property is further improved.
