CONSTITUTION:The mechanism consists of a rotary plate 4 attached axially to a necessary frame 2, and a motor 6 provided so as to correspond to the rotary plate 4, and said motor 6 is provided so as to be freely oscillatable forward and backward by setting a necessary part as a turning supporting point A, and also, while working one end of the motor 6 as a point of force, a rotary shaft 8 of the other end thereof is pressed and brought into contact with the rotary plate 4, therefore, a transmission mechanism such as a gear mechanism, etc., is not required at all, and by only driving the motor 6, the rotary plate 4 can be operated to rotate directly by its rotary shaft 8 itself.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to an operating mechanism for a rotary plate in advertising devices, toys, and the like.

[Conventional technology and its problems]

Conventionally, as an operating mechanism for a rotary plate in, for example, an advertising device, the mechanism shown in FIG. 4 is known, and this will be explained based on the same figure.

That is, in the figure, 101 is a rectangular frame that can be freely erected, 102 is a circular rotary plate that is mounted inside the frame 101 in a flat U-shape and is pivoted via an arm 103, and 104 is the axis of the rotating plate 102, and 105 is the rotating plate 102.
The motor is attached to the arm 103 in accordance with
106 is the rotating shaft 107 of the motor 105 and the rotating plate 102
This is a gear mechanism that connects the shaft 104 of the

In the advertising device configured as described above, by driving the motor 105, the rotary plate 102 is rotated through the gear mechanism 106.
This allows the user to rotate the unit in a predetermined direction.

By the way, since the rotary plate 102 in the conventional advertising device is rotated by the motor 105 via the gear mechanism 10B, the rotary plate 102 can always be rotated reliably at a constant speed. It is complicated and very troublesome to manufacture, and not only does it lead to an increase in cost, but it also has the disadvantage of being relatively easy to increase in size. Further, since the gear mechanism 106 is used, necessary maintenance such as oiling is required, which is extremely troublesome.

This invention aims to solve the conventional problems at once and provide an actuation mechanism that allows a rotary plate to be directly rotated by a motor without using a transmission mechanism such as a gear mechanism. .

[Means for solving problems]

That is, this invention consists of rotating plates 4 and 24 that are pivoted to the required frames 2 and 22, and motors 6 that are disposed corresponding to the rotating plates 4 and 24. The motor 6 is provided so as to be swingable back and forth with the rotation fulcrum A, and one end of the motor 6 acts as a power point, while the rotating shaft 8 at the other end is brought into pressure contact with the rotating plates 4 and 24. .

[For production]

By driving the motor 6, the rotating shaft 8 can directly rotate the rotating plates 4 and 24.

〔Example〕

An embodiment of the present invention shown in the drawings will be explained below, excluding tax.

1 is a stand, 2 is a substantially isosceles triangular plate-shaped frame integrally provided with the stand l, 3 is a rectangular opening formed approximately in the middle of the frame 2; Opening 3
A circular rotary plate 5 is pivotally attached to the front surface of the frame 1 to cover the frame 1, and 5 is the axis of the rotary plate 4, and a required advertisement display is displayed on the front surface of the rotary plate 4. Reference numeral 6 denotes a motor disposed in the opening 3 of the frame 2 corresponding to the rotary plate 4, and the motor 6 has a pair of motors on both sides in order to swing back and forth with its 11j end serving as a rotational fulcrum A. The motor 6 is mounted on a shaft between the arms 7, and the rotary shaft 8 of the motor 6 is mounted on #i7 by using the weight of the rear end of the motor 6 as a point of force.
7 and is pressed into contact with the back surface of the rotary plate 4. 9
Reference numeral 1 denotes a substantially arc-shaped advertising attachment member provided above the back surface of the rotary plate 4 so as to be freely protrusive and retractable, IO a lift bar for moving the advertisement attachment member 9 into and out, and 11 a rotary plate for raising and lowering the A-lowering bar 10. A connecting rod 12 is connected to the shaft 5 of 4, and 12 is a guide member of the lifting bar 10. In addition, 13 indicates a storage box for dry batteries that has been replaced with stand l.

Next, the operation of the above embodiment will be explained.

First, the motor 6 is started and its rotating shaft 8 is rotated. Then, the forward-inclined rotary shaft 8 is brought into strong pressing contact with the back surface of the rotary plate 4 by swinging the free rear part of the motor 6 around the pivot point A and acting as a force point, so that the frictional force becomes f. #A, the rotary plate 4 is rotated in the direction shown by the arrow in FIG. At this time, even if there is some unevenness on the back surface of the 1-turn plate 4, since the rotating shaft 8 is brought into contact with it while swinging, there is no risk of hindering the rotation of the rotating plate 4. When the plate 4 starts rotating, the lifting bar 10 moves in conjunction with the rotation of the rotating plate 4.
moves up and down to cause the advertising attachment member 9 to appear and disappear above the back surface of the rotary plate 4.

FIG. 3 shows another embodiment, in which a small-diameter circular rotary plate 24 is pivotally attached to a plate-like frame 22 erected on the side of a dry battery storage box I3, and a motor 6 is attached to the lower end of the outer circumference of the rotary plate 24. This embodiment differs from the previous embodiment in that the rotary shaft 8 of the embodiment is brought into pressure contact with the other parts, and the other parts are the same, and the same reference numerals indicate the same parts.

In the above embodiment, the rotary plates 4 and 24 are formed in a circular shape, but it goes without saying that they may be formed in a known shape such as an ellipse, a square, or a polygon. Moreover, although the above-mentioned embodiment shows an example of application to an advertising device, the present invention is not limited thereto, and can also be suitably applied to the rotation operation of a rotary plate in a toy or the like.

〔Effect of the invention〕

According to this invention, the required frames 2.2
2, and a motor 6 disposed corresponding to the rotary plate 4, 24.
is provided as a rotation fulcrum A at a required location so as to be able to swing back and forth, and one end of the motor 6 acts as a point of effort while the rotation shaft 8 at the other end is brought into pressure contact with the rotation plates 4 and 24. Therefore, by simply driving the motor 6, the rotary plate 4φ24 can be directly rotated by the rotary shaft 8 itself, without requiring any transmission mechanism such as a float mechanism as in the past. It is. In addition, since the motor 6 is able to swing back and forth with a predetermined point as the rotation fulcrum A, even if there are some irregularities on the back surface or outer peripheral surface of the rotary plates 4 and 24, the rotary shaft 8
Because it is possible to make pressure contact while rocking the
There is no possibility that the rotational operation of the rotary plates 4 and 24 will be hindered. Further, since the present invention has an extremely compact structure without requiring a gear mechanism or the like, it is extremely easy to manufacture and can be provided at low cost.
