Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a display device used for signboards, guide boards, indoor and outdoor decorative boards, 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. Furthermore, in this type of display device, one has been proposed in which the internal lighting is blinked or the amount of light is changed, or a plurality of light sources of different colors are used to make the display more eye-catching.

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

(Problems 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 when the same display needs to continue and attract attention. It was hot.

Moreover, at present, each conventional type as mentioned above is
Since all of them are widely used and obsolete, there is a need for new and interesting display devices 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, combinations thereof, etc. in the base color or background color of the display formed on the display board. By forming fine meshes, forming the same or different meshes on the light-shielding plate superimposed behind the display board according to the position of the mesh, and moving these display boards and the light-shielding plate relatively, The mesh of the display board and the light shielding board are shifted in position.

(Function) In the present invention having the above 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 example of the present invention will be described in detail with reference to the drawings.

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

In this embodiment, the display plate 40 and the light shielding plate 41
Both are made of a cylindrical transparent synthetic resin material, and are arranged concentrically inside and outside of a support tube 42, which is also made of a cylindrical transparent member. This support cylinder 42 corresponds to one of the support members described in the claims of the present invention. That is, from the inside,
The light shielding plate 41, the support tube 42, and the display plate 40 are concentrically overlapped in this order. The support tube 42 sandwiched between them is taller than the display board 40 and the light shielding plate 41, so that when this device is placed on the floor, only the bottom of the support tube 42 will touch the floor. The inner and outer display boards 40 and the light shielding plates 41 do not touch the floor.

A display 40a and a background 40 are provided on the surface of the display board 40.
b is drawn, and a mesh is formed in the transparent display 40a portion. On the other hand, the inner light shielding plate 4
1 is also formed with a mesh 41a. 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 roughness of each part of each board or between the display board 40 and the light shielding plate 41 is different. , the spacing, and direction are different.

In this embodiment, the display and background are created by pasting a transparent film on which the display and background are printed on the back of the display board 40 and light shielding board 41, which are made 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 the light shielding plate 41, or may be written by hand. In addition, the light shielding plate 41
The mesh is preferably formed larger than that on the display board 40, considering that the light shielding plate 41 and the display board 40 move relative to each other.

A second support member 43 for supporting a drive device in the diametrical direction is fixed to the upper part of the support tube 42, and a drive device 44 incorporating a motor or the like is provided on this support member 43. This drive device 44 includes a display plate 40 that rotates in the opposite direction.
Two motors 45 and 46 are incorporated, one for the light shielding plate 41 and the other for the light shielding plate 41. On the other hand, third and fourth 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 43 provided on the light shielding plate 41 is provided below the drive device 44. Further, the output shaft of the display board motor 45 provided in the drive device 44 is fixed at the center of the display board support member 47, and the output shaft of the light shielding plate motor 46 is fixed at 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, a ring-shaped fluorescent light is used, for example, and is mounted on a stand 50 installed on the floor. This stand 50 corresponds to a support member that supports a light source in the claims of the present invention.

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

In this embodiment having such a configuration, when the light source 49 is turned on and the motors 45 and 46 of the drive device 44 are operated, the motors 45 and 46 are activated.
Support members 47, 48 connected to the output shaft of
The display panel 40 and the light shielding plate 41 are rotated in opposite directions through the display panel 40 and the light shielding plate 41. 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 manner, when the display plate 40 and the light shielding plate 41 rotate relative to each other, the meshes formed on both of them are displaced from each other, and the lines of both meshes overlap or separate. That is,
If you look closely, the display on the front panel 40 and the transparent area between the meshes in the background part will be closed or opened by the lines of the mesh on 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 FIGS. 2 and 3 show a second embodiment of the present invention, in which the present invention is applied to a lampshade.

In this embodiment, the display plate 60 and the light shielding plate 6
1 has a conical shape with a flattened top, and both are coaxially overlapped with each other so that the display plate 60 is on the outside as shown in the sectional view of FIG. A stand 63, which is a supporting member of the present invention, is provided in the space inside the display board 60 and the light shielding plate 61.
A motor 64 is built in the upper part of 3. 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 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.
5 meshes with a third bevel gear 67 fixed to the center of the light shielding plate 61 via a transmission bevel gear 66 rotatably supported on a stand 63. Further, a light source 68 made of a ring-shaped fluorescent lamp is provided on the outer periphery of the stand 63.

In this embodiment with such a configuration, when the motor 4 rotates, the display plate 60 directly fixed to its output shaft rotates, and at the same time, the motor 6
A light shielding plate 61 interlocked with the output shaft of No. 4 via bevel gears 65 to 67 rotates in the opposite direction to the display plate 60. As a result, the meshes provided on both patterns or background portions are displaced from each other, and a flickering striped pattern can be drawn that moves to the pattern or background portion.

Other Embodiments Although the present invention includes the embodiments described above, 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 you change the rotation direction of each light shielding plate or change the shape and arrangement of the mesh,
The pattern of light intensity changes becomes complex and interesting.

b. Instead of shielding the entire back of the 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. vice versa,
It is also possible to arrange a plurality of display boards for one light shielding board.

c In the first embodiment, the light-shielding plate can be fixed and only the display plate can be moved as in the second embodiment, or conversely, the display plate can be fixed and the light-shielding plate can be moved without using the support cylinder as a support member. It can also be moved. In this case, the fixed member also serves as a support member for another member.

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

e Transparent materials such as synthetic resins such as acrylic and glass can be used as display boards and light shielding plates, but in addition to colorless transparent materials, colored transparent materials or meshes drawn on the surface of colorless transparent materials may be used. A colored film may also be attached. 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 light intensity of the light source itself, which is unprecedented. Unique display effects can be obtained. In particular, the interference phenomenon of light using mesh allows the patterns and backgrounds on display boards to appear as if they are moving minutely. There are display effects that cannot be achieved with the display boards used.

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.

In addition, 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.

Furthermore, according to the present invention, the following remarkable effects can be expected.

By illuminating the inside of the display board and the light shielding plate with a light source, the moiré effect is excellent.

The support member integrally supports the display board, the light shielding plate, and the drive motor. Therefore, the display device can be easily moved by lifting the support member, and can be used for purposes such as interior decoration items or light stands that are intended to be carried.

Since the drive motor and light source are provided on the support member inside the cylindrical display plate and the light-shielding plate, they are not exposed to the outside and look good when used as indoor equipment or advertising equipment.
