Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a rotary display device for attracting people's attention for advertisements and the like.

<Prior Art> Conventionally, a rotary display device is constructed by attaching a display plate to a rotating arm fixed to the rotating shaft of a motor, and the display plate is rotated by the rotation of the rotating arm.
Because the motion was simple, rotating around the rotation axis of the motor, viewers quickly got bored with it, and the attracting effect was not necessarily satisfactory.

<Problems to be solved by the invention> The invention addresses the above-mentioned difficulties.The purpose of the invention is to rotate the display board around the axis of rotation of the motor, and to prevent irregularities during this rotation. The purpose is to provide a display device that rotates on its own axis and has a good effect on attracting general consumers.

<Means for solving the problem> The present invention forms a case in which a magnetically permeable plate with slipperiness is attached to the front, a motor is installed in this case, and a rotary plate is fixed to the rotating shaft of the motor. , An arbitrary number of magnets are attached to this rotary plate in correspondence with the magnetically transparent plate, and an arbitrary number of display plates are arranged on the outside of the case, and a magnet is attached to the rotating plate at a position offset from the center of gravity of this display plate. It has a magnet attached that attracts it.

<Function> In this display device having the above configuration, when the rotating plate rotates due to the rotation of the motor, the magnet of the display plate is attracted to the magnet of the rotating plate, so that the display plate is attached to the magnetically transparent plate on the outside of the case. Since the display board's magnet is offset from the center of gravity, centrifugal force and gravity act on the display board during the rotation, causing it to rotate irregularly.

<Example> Examples will be described in detail below.

Reference numeral 1 denotes a case, and a magnetically transparent plate 2 having smoothness is attached to the upper part of the front surface. As the magnetically transparent plate 2, a thin glass plate having slipperiness, a synthetic resin plate, a non-magnetic metal plate, etc. can be considered. 3 is a motor, which is fixed to the rear plate 4 inside the case 1. Reference numeral 5 denotes a circular rotating plate, and the rotating shaft 6 of the motor 3 is connected at the center so as to correspond to the magnetically transparent plate 2.
and is rotated by the rotation of the motor 3. A plurality of magnets 7, 7 are attached to the rotary plate 5 in correspondence with the magnetically transparent plate 2, and a small interval 8 is formed between the magnets 7, 7 and the magnetically transparent plate 2. Reference numerals 9 and 9 denote display plates arranged on the outside of the case 1, and a magnet 10 is attached to the back surface of each display plate at a position offset from the center of gravity. The two display plates 9, 9 are attracted by the magnetic force of the magnets 7, 7 of the rotary plate 5, which transmit the magnets 10 on the back surface of the display plates 2, and come into contact with the outside of the magnetically transparent plate 2. An advertising display board 11 to which advertising labels, advertising boards, etc. are attached is attached to the lower front part of the case 1. 12 is a cord that supplies current to the motor 3.

Therefore, when the motor 3 is rotated, the rotating plate 5
rotates, and the magnets 10, 10 of the display boards 9, 9 are attracted to the magnets 7, 7 of this rotary plate 5, so
The display plates 9, 9 rotate around the rotation axis of the motor 3 so as to slide on the magnetically transparent plate 2. Since the magnets 10, 10 of the display boards 9, 9 are installed at positions shifted from the centers of gravity of the display boards 9, 9, gravity and centrifugal force act on the display boards 9, 9 during the above-mentioned rotation, causing them to become unstable. It becomes stable and rotates irregularly as if sliding on the magnetically transparent plate 2. The rotation process of the display board 9 will be explained in detail with reference to the schematic diagram of FIG.

The magnet 10 of the display board 9 is attached at a position offset from the center of gravity, so when the rotary plate 5 is stopped, gravity acts and the magnet 10, which serves as a fulcrum, is positioned upward as shown in Figure A. It is in a drooping state. In this state, when the motor 3 is driven to rotate the rotating plate 5, the display plate 9 rotates around the rotating shaft 6 of the motor 3 as described above. In addition to the gravitational force that tries to keep the center of gravity at a low position, centrifugal force acts, creating an unstable state, so the display board 9 rotates while sliding on the slippery magnetically transparent board 2. do. During this rotation, if centrifugal force overcomes gravity, the state will change from diagram A to diagram B or diagram C, then inertia will be added to this, resulting in diagram D, then gravity will act, and the state will change to diagram A through diagram B or C. It rotates around the magnet 10 as a fulcrum in this state. If the rotation speed is high, the inertial force will be large, so it will rotate several times in succession. When it returns to the state shown in Figure A, it rotates around the rotating shaft 6 while rocking again, but on the way, it repeats its rotation in the same way as above. The display board 9 rotates many times during one rotation of the rotating shaft 6, and the direction,
The location, frequency and speed are not constant and are always irregular.

In the above embodiment, two magnets are attached to the rotary plate, and two display boards each having a magnet attracted to each magnet are arranged, but the present invention is not limited to this. By attaching one or more magnets to the rotating plate and arranging display boards in correspondence with the magnets, it is possible to increase the number of display boards to one or more. Further, the shapes of the rotating plate and the display plate are not limited to the above embodiments, and various shapes can be considered.

<Effects of the Invention> As is clear from the description of the embodiments above, in the present invention, the display board rotates on the magnetically transparent board around the rotating shaft of the motor, and during this rotation, the direction, location, Because it rotates irregularly, with an inconsistent number of times and speed, it attracts the attention of general consumers, and viewers watch the display for a long time as they look forward to seeing it rotate one after another with interest. Attracted by the movement of the board, the user's eyes will naturally be drawn to the advertising display board located below the magnetically transparent board, thereby improving the effectiveness of advertising.
