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 is to create a dynamic light ring on the edges of both the front and back surfaces to create an interesting display, and to effectively integrate the two translucent base plates with mounting members such as a drive motor. It is something.

Structure of the Invention In order to achieve the above object, the present invention provides two transparent sheets that are stacked on top of each other, have a through hole in the center, and have an inclined reflective surface at the outer end that reflects light to the outer surface. A base plate, a driving motor disposed within the through hole, a light source lamp also disposed within the through hole, and a light source lamp configured to be rotated by the driving motor to change the transmitted light. A rotating body having a circumferential body with a pattern or the like placed between the light source lamp and the end face of the through hole, and a display panel disposed in front of the through hole of each of the light transmitting base plates, The motor and the light source lamp are attached to a holding plate, and the end of the holding plate is attached to the translucent base plate with screws, and the two translucent base plates are joined by the mounting screws. With this configuration, it is possible to illuminate both the front and rear display panels with a single light source, and it is also possible to make a dynamic light ring appear on the edge portions of both the front and rear surfaces for effective display. Furthermore, the two translucent base plates can be effectively integrated without requiring any special means for coupling them.

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, the annular wall 6;
Ribs 8, 8' are provided on the outer periphery of 6' to form concave grooves 7, 7' between the annular walls 6, 6'. The edge portions of the translucent base plates 4, 4' are formed as follows. That is, the through hole 5 is provided at the outer peripheral end.
Light reflecting surfaces 9, 9' are formed which are inclined with respect to the axis of light introduced from 5'.
Projected portions 10, 10' are provided on the outer surface portion corresponding to 9', and these portions serve as halo-ring-exposing 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 made up of members 12a and 12b that are divided into left and right halves in advance, each having a U-shaped cross section, and clamping the outer peripheral edges of the translucent base plates 4 and 4'. are connected by a connecting member 13 (see FIG. 6).

This connecting member 13 is adapted to fit within a gap 11 formed between the outer peripheral edges of the translucent base plates 4, 4'. Further, when a mounting member 14 such as a stand is coupled to the frame member 12 as shown in FIG. 2, the ends of the screws 15 and nuts 16 are also accommodated in 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 translucent 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 body portion 24 is provided with a suitable discontinuous pattern or coloring. Therefore, the light from the light source lamp 20 passes through the peripheral body 24 to the transparent base plates 4, 4'.
The light is applied to the end faces of the through holes 5, 5', and discontinuous light is applied by rotating the circumferential body 24. 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 its base end is inserted between the grooves 7, 7' formed between the annular walls 6, 6' and the ribs 8, 8'. ing. The base ends of the holding frames 27, 27' are provided with seal rings 29, 2 made of rubber or the like provided in the grooves 7, 7'.
9'. It is fixed to the annular walls 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 appears at the outer edge of the outer surface of each of the translucent base plates 4, 4', and since this is dynamic due to the rotation of the rotating body 21, it gives a strong visual impression. Also, auxiliary reflective surface 1
8 and 18', light is similarly reflected, and a discontinuous light ring with a small width appears on the surface of the translucent base plates 4 and 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 has a fixing function but also shields the light. Contributes to the appearance of the halo.

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 through 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, and the illumination light changes depending on the circumferential body of the rotating body. Since it is light, it has a great visual effect.

In particular, the drive motor, rotary body, and light source lamp are held by the holding plate and placed in the through hole of the translucent base plate, which reduces the thickness of the illuminated signboard and is advantageous as a double-sided illumination type. When the plate is attached to the light-transmitting base plate, the two light-transmitting base plates are joined together, and there is no need for special means for joining, which is advantageous in terms of assembly.
In an illuminated signboard in which two translucent base plates are stacked one on top of the other for display on the front and back, its practical effects are extremely large.
