Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a device for rotating a small signboard for advertising or promotion, or a case containing an air freshener or the like.

(Prior Art) The devices shown in FIGS. 6 and 7 have been considered as devices for rotating small strip-shaped billboards for advertising and publicity indoors using solar cells without using a commercial power source.

In this device, a support 101 having an insertion hole 101a is attached to a fluorescent lamp 100.
A motor 103 is suspended from the motor 103 via a wire 102, a small signboard 106 is suspended from the drive shaft 104 of the motor 103 via a chain 105, and a solar cell 107 is attached to the back side of the upper surface 101b of the support 101. The motor 103 is driven by the electromotive force generated in the solar cell 107 when the fluorescent lamp 100 is turned on, and the small signboard 106 is rotated.

(Problems to be solved by the invention) In the conventional rotating device described above, the support 1
By passing the fluorescent lamp 100 through the insertion hole 101a of 01, the structure is such that the fluorescent lamp 100 supports the support 101, the motor 103 connected to this, and the small signboard 106, thereby reducing the weight of the support 101, etc. There is a risk that the fluorescent lamp 100 will be damaged due to the direct effect on the fluorescent lamp, and it is not possible to connect a motor with a large capacity or a rotating body with a large weight to the motor.

Further, conventional rotating devices can only be applied to straight tube fluorescent lamps due to the structure of the support. Therefore, it is conceivable to attach the motor 103 to the ceiling or the like, but in this case, the problem arises as to where to place the solar cells.

That is, the shapes and positions of indoor lights differ from room to room, and even if these indoor lights of different shapes and positions are used as light sources, it is necessary to always ensure that the solar cells receive light in an optimal state.

(Means for Solving the Problems) In order to solve the above problems, the rotating device according to the present invention supports the motor that rotates the rotating body on a strong part such as the ceiling, and supports the motor at a distance from the motor. The base end of a flexible arm was attached to the position, and a solar cell was attached to the tip of this flexible arm so that the angle could be adjusted.

(Function) By extending and contracting the flexible arm, the solar cell can be brought closer to a light source such as an indoor light or a window, and by further adjusting the angle of the solar cell, light can be applied to the solar cell in an optimal state.

(Example) An example of the present invention will be described below based on the accompanying drawings.

FIG. 1 is an overall view of the rotating device according to the present invention. This rotating device has an incandescent lamp 2 as a light source and a motor 3 attached to the ceiling 1 of the room, and a rod 4 etc. is connected to the drive shaft of the motor 3. A rotating body 5 is suspended. The rotating body 5 may be used, for example, as a case for storing solid medicines such as aromatics, deodorizers, or air fresheners, a small signboard with advertising/promotional phrases, or even an indoor sign for emergencies.

Further, a flexible arm 6 is provided between the incandescent lamp 2 and the motor 3. This flexible arm 6 consists of two pipes 7, 8, and these pipes 7, 8 are connected to a second
As shown in the figure, they are rotatably connected via a joint 9, and the base end of the pipe 7 is fixed to the ceiling 1 via a joint 10, a metal fitting 11, and a screw 12.
Further, a solar cell 14 is attached to the tip of the pipe 8 via a joint 13 so that its angle can be adjusted. Further, the solar cell 14 and the motor 3 are electrically connected by a wiring 15 passing through the pipes 7 and 8.

In the above process, the solar cell 14 is brought closer to the incandescent lamp 2 by extending and contracting the flexible arm 6, and the incandescent lamp 2 is turned on while the angle of the solar cell 14 is further adjusted.
Then, the light from the incandescent lamp 2 generates an electromotive force in the solar cell 14, and this electromotive force drives the motor 3 and rotates the rotating body 5.

3 to 5 are views showing a rotating device according to another embodiment, and in the embodiment shown in FIG. 3, an incandescent lamp 2 and a flexible arm 6 are attached to a side wall 16 in the room. In the embodiment shown in FIG. 4, the light source is a fluorescent lamp 17 attached to the ceiling 1, and the base end of the flexible arm 6 is attached to the cover 18 of the light source lamp 17. In the embodiment shown in FIG. 5, the window portion 19 is used as a light source,
The base end portion of the flexible arm 6 is attached to the side wall 16 forming the window portion 19.

In either embodiment, an electromotive force is generated in the solar cell by the light from the light source, and the motor is rotated by this electromotive force.

(Effects of the invention) As explained above, according to the invention, the solar cell that supplies power to the motor that rotates the rotating body is attached to the tip of the flexible arm so that the angle can be adjusted. Regardless of the shape or location, the solar cells can be illuminated with light under optimal conditions, and the motor is supported on a strong member such as the ceiling. , even if the weight of the rotating body is large, there will be no problem, and many other effects will be exhibited.
