Description

DETAILED DESCRIPTION OF THE INVENTION OBJECT OF THE INVENTION (Industrial Field of Application) The present invention relates to a display device used for stone boards, guide boards, decorative boards inside and outside the university, lampshades, and the like.

(Prior Art) Among conventionally known display devices, one is known that provides illumination from behind the display. This type of device has the advantage that the display stands out clearly from its background, making it easier to see than other display devices that rely on external lighting. It is also being proposed that the display device of this scale may be designed to attract attention by blinking the internal lighting or changing the intensity of the light, or by using multiple light sources with different colors. .

Furthermore, like barber shop signboards, there are also known signs in which the display pattern can be changed by moving the display itself or by overlapping two display boards and avoiding moving one of them.

(Problem to be solved by the invention) However, conventional display devices that use a blinking light source have the disadvantage that the display is difficult to see because the change in light intensity is too large and the blinking interval cannot be shortened beyond a certain level. . on the other hand,
Conventional display devices that move the pattern, such as barber shop signboards, move and change the large pattern itself, making it unsuitable for situations where the same display needs to continue and attract attention. Rarely.

Furthermore, since all of the above-mentioned conventional types are now widely used and obsolete, there has been a demand for a new and interesting display device to replace these conventional types.

The purpose of the present invention is to extremely finely change the background color of the display or the brightness of the background without changing the shape and arrangement of the display itself. It is an object of the present invention to provide a display device that allows minute pattern changes in the display itself as described above without blinking the light source or changing the amount of light.

[Structure of the Invention] (Means for Solving the Problems) The display device of the present invention has grids, parallel lines, radial lines, or combinations thereof on the ground color or background color portion of the display formed on the display board. ! A fine mesh such as the above is formed, and the same or a different mesh is formed on the light shielding plate superimposed behind this display board according to the position of the mesh, and the display board and the light shielding plate are moved relative to each other. As a result, the meshes of the display plate and the light shielding plate are shifted in position.

In particular, the present invention provides that the display plate and the light shielding plate have a cylindrical shape, a prismatic shape,
It is characterized by being constructed from a cylindrical member such as a conical shape.

(Function) In the present invention having the above-mentioned configuration, as the meshes provided on the display board and the light shielding plate move relative to each other, a moiré phenomenon occurs in which the mesh portion of the display board moves. , it is possible to cause minute pattern changes such as flickering or blinking on the display board.

In particular, in the present invention, since the display board and the light-shielding board are composed of cylindrical members, the display changes sequentially and is displayed endlessly at the same time as the pattern of the display itself changes. You can also view the display from

(Example) Hereinafter, an actual pressure example of the present invention will be specifically described with reference to the drawings.

(1) First Embodiment As shown in the exploded perspective view of FIG. 1, in this embodiment, the display plate and the light shielding plate are constructed from cylindrical members arranged concentrically.

In this embodiment, the display plate 40 and the light shielding plate 41 are both made of a cylindrical transparent synthetic resin material, and are arranged concentrically inside and outside a support tube 42 which is also made of a cylindrical transparent member. That is, from the inside, the light shielding plate 41 and the support tube 42
, display board 40 are concentrically overlapped in this order. The support tube 42 sandwiched between the display panel 40 and the light shielding plate 4
1, and when this device is placed on the floor, only the bottom of the support tube 42 touches the floor, and the inner and outer display boards 40 and the light shielding plate 41 do not touch the floor.

A display 40a and a background 40b are drawn on the surface of the display board 40, and a mesh is formed on the transparent display 40a. On the other hand, a mesh 41a is also formed on the inner light shielding plate 41. These meshes may be the same over the entire surface of the display board 40 and the light shielding plate 41, but in this embodiment, the meshes are the same for each part of each board or for the display board 40 and the light shielding plate 41.
The roughness, spacing, and direction are different.

J3, in this embodiment, the display and background are made by pasting a transparent film with a display and a blue label printed on the back of the display board 40 and light shielding board 41 formed of transparent plates such as acrylic boards. However, it may be printed directly on the front or back surface of the transparent display plate 40 or light shielding plate 41, or may be handwritten directly. Further, the mesh of the light shielding plate 41 is desirably formed to be larger than that on the display plate 40, considering that the light shielding plate 41 and the display plate 40 move relative to each other.

A support member 43 of a drive device is fixed to the upper part of the support tube 42 in the diametrical direction thereof, and a drive device 44 incorporating a motor etc. is mounted on this support member 43. This drive device 44 incorporates two motors 45 and 46, one for the display plate 40 and one for the light shielding plate 41, which rotate in opposite directions. On the other hand, support members 47 and 48 are also provided at the upper ends of the display board 40 and the light shielding board 41 in the diametrical direction thereof, respectively. Among these, the support member 47 provided on the display board 40 is provided above the drive device 44, and the support member 47 provided on the light shielding plate 41 is provided above the drive device 44.
3 is provided below the drive device 44. Further, the output shaft of a display board motor 45 provided in the drive device 44 is fixed to the center of the display board support member 47, and the output shaft of the light shielding plate motor 46 is fixed to the center of the light shielding plate support member 48. ing.

As described above, in the device of this embodiment, the display plate and the light shielding plate have a cylindrical shape, so the light source 49 is arranged in the central space. As this light source 49, for example, a ring-shaped fluorescent lamp is used, and a stand 50 installed on the floor
installed on top.

Note that the power cord of the light source 49, the ballast for the fluorescent lamp, the power source of the drive device 44, etc. are omitted in the figure. Although the light source 49 is a plurality of fluorescent lights in this embodiment, the type and number of lights may be used as long as the light is irradiated to the outside through the gap between the mesh of the display board 40 and the light shielding board 41. There are no particular restrictions.

In this embodiment having such a configuration, the light source 49
When the light is turned on and the motors 45 and 46 of the drive device 44 are operated, the display board 40 and the light shielding board 41 are rotated in opposite directions via the support members 47 and 48 connected to the output shafts of the motors 45 and 46. do.

The speed of this rotation can be selected as appropriate, but if it is too fast, the striped pattern will move too quickly due to light interference, making it impossible to obtain a flickering or blink-like pattern change, so it should be set at an appropriate speed.

In this way, when the display board 40 and the light shielding board 41 rotate relative to each other, the meshes formed on both of them shift in position with respect to each other, and the lines of both meshes move toward or away from each other. That is, if you look closely, the transparent part between the meshes of the display and background part of the front panel 40 will be closed or opened by the lines of the mesh of the light shielding plate 41 behind, and as a result, the light from the light source 49 will be Intercepted at very small intervals. Therefore, the display and its background can flicker or blink to attract the viewer's attention.

■Second Embodiment Figures 2 and 3 show a second embodiment of the present invention.
In this embodiment, the present invention is applied to a lamp shade.

In this embodiment, the display plate 60 and the light-shielding plate 61 have a conical shape with a flat top, and they are coaxially stacked so that the display plate 60 is on the outside as shown in the cross-sectional view of FIG. It is matched. A stand 63 is provided in the space inside the display board 60 and the light shielding plate 61, and a motor 6 is installed in the second part of this stand 63.
4 is built-in. The output shaft of the motor 64 passes through the upper part of the stand 63 and the upper part of the light shielding plate 61 four times and is fixed to the center of the display board 60. Further, a bevel gear 65 is fixed to the output shaft of the motor 64, and this bevel gear 65 is connected to the base 63.
It meshes with a third bevel gear 67 fixed to the center of the light shielding plate 61 via a transmission bevel gear A766 rotatably supported by the shielding plate 61 . Further, a light source 68 consisting of a ring-shaped fluorescent lamp is provided on the 63rd outer periphery.

In this embodiment having such a configuration, when the motor 4 rotates, the display plate 60 directly fixed to the output shaft of the motor 4 rotates, and at the same time, the bevel gear 65 is connected to the output shaft of the motor 64.
The light shielding plate 61 interlocked with the display plate 60 through 67 rotates in the opposite direction to the display plate 60. As a result, the meshes 1 provided on both patterns or background parts are displaced from each other, and a flickering striped pattern can be drawn that moves to the pattern or background part.

■Other Examples Although the present invention includes the above-mentioned embodiments, it is not necessarily limited thereto, and also includes other embodiments as described below.

a. The number of light shielding plates is not limited to one, and a plurality of light shielding plates may be stacked and provided behind the display board. In that case, if the direction of rotation of each light-shielding plate is changed or the shape or arrangement of the meshes is made different, the pattern of change in the front set becomes complex and interesting.

Instead of shielding the entire back of the b1 display board from light with one light shielding plate, it is also possible to provide light shielding plates that move in different directions for each part of the display board. Conversely, it is also possible to arrange a plurality of display boards for one light shielding board.

C1 In the first embodiment, the light shielding plate can be fixed and only the display board can be moved as in the second embodiment, or conversely, the display board can be fixed and the light shielding plate can be moved without using the support tube. You can also do it.

d. As a light source, in addition to the fluorescent lamps shown in each embodiment, incandescent lamps and other known means can be used. It is also possible to use natural light or other external lighting without having a built-in light source.

e. Instead of rotating the cylindrical display plate and light shielding plate in the fourth embodiment, one can also be moved vertically relative to the other.

f. Instead of the cylindrical or conical display plates and light shielding plates of the first and second embodiments, polygonal cylindrical or polygonal pyramidal display plates and light shielding plates may be used.

9. Transparent members made of synthetic resin such as acrylic or glass can be used as display boards and light-shielding plates, but in addition to colorless transparent members, colored transparent members may be used, or mesh may be applied to the surface of colorless transparent members. You can also attach a colored film with your drawing. Further, each part of the display board or light shielding plate may be colored differently.

[Effects of the Invention] As described above, according to the display device of the present invention, it is possible to make the ground color or background of the display flicker or blink without blinking or changing the priority of the light source itself, which is different from the conventional display device. You can get unique display effects. In particular, according to the light interference phenomenon using a mesh, the pattern and background of the display board appear as if they are moving minutely.
Display effects such as the brilliance of the sun, the twinkling of stars, and the reflection of light from ripples are impossible to achieve with display boards that use conventional lighting.

In particular, in the present invention, since the display board and the light-shielding board are constructed from cylindrical members, it is possible to provide an endless display of patterns etc. around the display board, and at the same time the pattern itself changes due to the mesh. Since the display changes sequentially, an excellent display effect can be obtained. Another advantage is that the same display can be viewed from any position around the device.

Furthermore, if the shape, roughness, and direction of the mesh are changed for each part of the display board or light-shielding plate as in the illustrated embodiment, the interference patterns that occur will differ even for the same display, so it will appear as if the displays are different. The display effect is very good.
