Description

[Detailed Description of the Invention] The present invention provides an advertisement in which a large number of colored strips are danced around in a display space, and at the same time these strips can form a display of desired characters, symbols, figures, etc. The present invention relates to a display device for use with computers.

This type of device includes, for example, a double wall or a square column with a display space inside, or a cylindrical structure with a transparent wall on one side or the entire circumference, and an air inlet and a suction port at an appropriate position in the inner display space. A device is provided with an opening or a delivery port to cause powder or powder pieces to dance wildly within the display space through air circulation, or a wall that defines the dancing space at the same time as the powder or powder pieces dance wildly in the display space. A display screen in the shape of desired characters, symbols, or designs is provided in a part of the display screen, which is made up of many small holes, and each of the small holes in the display screen is connected to an air suction port or an air output port, and powder or powder is scattered around. There are known devices in which pieces can be attached to a display screen to form a desired display. In addition to the decorative and display effects provided by such known devices, devices have already been proposed that allow, for example, product samples and products themselves to be directly displayed together.

However, in such prior art devices,
Powder pieces and pieces adsorbed to the display screen are difficult to fall off the display screen when the device is stopped, and some of them remain as they are, making them unsightly and reducing the decorative effect by half. In addition, some of the powder particles and pieces may remain attached to the transparent walls that define the display space. The main causes of this condition are static electricity and moisture.
That is, during the relatively dry winter season, static electricity makes it difficult for adhering powder particles and debris to fall off, while during the rainy season, humidity is the cause. By the way, if the random pieces are made of metal, the problem of static electricity can be solved to some extent, but it is difficult to color them in the desired color to enhance the decorative effect, and there is also the problem of rust due to long-term use.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an advertising display device of the above type, which is equipped with a device for removing adhering stray pieces.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows an embodiment of the present invention, in which numeral 1 denotes an outer cylinder whose base is fixed to a support frame 2. As shown in FIG. Reference numeral 3 denotes an inner cylinder constituting a display panel, which is attached to the outer cylinder 1 so that it can rotate concentrically. A disk 5 forming the floor of a display room 4 for products, etc. is attached to the upper end of the rotating inner cylinder 3. A motor device 6 for rotationally driving the inner tube 3 is attached to the top of the outer tube 1 along with a control device thereof, and is closed with a detachable cap 7. This cap 7 is provided with a required number of heat radiation holes 7a. Further, 8 is a lamp for illuminating the display room 4.

Between the outer cylinder 1 and the inner cylinder 3, a display chamber 9 covering approximately 1/3 of the circumference is defined by partition walls 10, as shown in FIG. 2, and the surface of each partition wall 10 is made of aluminum. A mirror 10a is formed. In addition, each partition wall 10
A felt, a brush, a rubber band, or the like 11 is disposed between the inner cylinder 3 and the surface of the inner cylinder 3. The upper end of the display chamber 9 is sealed, and a blow-out portion 12 having a V-shaped cross section for accommodating the display forming strip is attached to the lower end. An air outlet 12a consisting of a large number of pores is provided at the lower end of this air outlet part 12,
A fan 13 attached to the lower end of the inner cylinder 3 causes the display forming strips in the blowout part 12 to fly upwards in the display chamber 9. The air blown up from the display chamber 9 is passed through a display screen 14 (for example, a screen or inner (which may be formed by etching a part of the cylinder 3) and flows down the inside of the inner cylinder 3 through the air outlet 12a again by the fan 13.
forced towards. The air circulation path thus formed is a closed path, but as the case may be, an appropriate number of air inlets or air outlets may be provided at appropriate positions in this path to control the scattering of the particles. A portion 12b of the balloon portion 12 is made of a transparent plate, and is configured such that the display chamber 9 can be illuminated by a lamp 15 mounted within the support frame 2. lamp 8,
15 can consist of different colored lamps if desired, or the color of the strips can be varied from time to time by rotating different colored filters around a regular lamp, thereby producing a decorative effect. can be increased.

Further, brushes 16 are installed in the inner cylinder 3 as shown, and the brushes 16 can be arranged in two or more rows. Yet another brush 1
6 may also be provided with a vibration device or a reverse injection device if necessary as a scraping device. Furthermore, anti-static brushes can be incorporated.

The portion of the outer tube 1 that defines the display chamber 9 is transparent, and its inner wall can also be made into an antistatic wall. Further, the portion of the outer cylinder 1 defining the display chamber 4 is preferably transparent over its entire circumference.

In the illustrated embodiment, the display chamber 9 is formed over about 1/3 of the entire circumference, but if necessary, a plurality of display chambers (for example, three at 120 degrees each) may be provided over the entire circumference. .

The outer cylinder 1 or the inner cylinder 3 may be configured to be easily removable to facilitate cleaning or repair of the device.

During operation, when the fan 13 is activated, that is, during a display operation in which a desired display is performed on the display screen 14 by scattering the pieces, the inner cylinder 3 is stationary;
Lamp 15 is turned on. After a certain period of time set by the timer, the fan 13 is stopped, the lamp 15 is turned off, and at the same time the inner cylinder 3 is rotated, and as a result, the felt or the brush 11 and the brush 16 that are in contact with the inner cylinder 3 are displayed. screen 14
The fine particles adhering to the area and its vicinity are scraped off. On the other hand, the lamp 8 is turned on, the interior of the display room 4 is illuminated, and people's eyes are drawn to the interior of the display room 4. In this case, if necessary, the interior of the display room 4 may be illuminated at all times. Also lamp 8 and lamp 15
can also be flashed at the same time.

Further, in a modified embodiment of the present invention, the inner cylinder 3 may be fixed and the brush 16 may be rotated, and instead of being provided along the vertical direction of the display screen 14, the brush 16 extends over the entire width of the display screen 14. It is also possible to provide an arc shape in contact with and move it up and down.

Furthermore, instead of the vertical device shown in the figure, it may be configured horizontally, in which case the outer cylinder may be made into a box shape, for example.
A display window is provided in at least a portion of the display window, and the inner cylinder is placed horizontally within the display window, so that characters, figures, etc. can be displayed in the same manner as in the previous embodiment. In this case as well, a device for scraping off fine particles can be provided, for example, around the display window or inside the inner cylinder, as in the previous embodiment. Further, a display room for products, etc. can be provided above the inner tube, at one end, or at both ends.

As explained above, according to the present invention, it is possible to reliably remove loose particles that adhere to the display screen due to static electricity or moisture and are difficult to remove.
There is provided an advertising display device which can further enhance decorative effects and display effects as compared to conventional devices and is low cost.
