Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a rotary decorative lamp whose shade is rotated by a motor.

Conventional structure and its problems Conventionally, in rotary decorative lights where the shade is rotated by a motor, there is a problem that if an impact is applied to the shade, the inside of the motor, especially the speed reduction mechanism, will be damaged, so it is not used in actual use.

Or there were some inconveniences in transportation.

OBJECTS OF THE INVENTION Accordingly, an object of the present invention is to provide a rotary decorative lamp in which the motor is extremely unlikely to be damaged even if a shock is applied to the shade.

``Structure of the Invention'' - In order to achieve the above-mentioned object, the present invention has a motor built into a main body, and a rotating shaft of the motor protrudes from a hole in an end surface of the main body formed with an inner diameter slightly larger than the outer diameter of the motor. In addition, the rotary decorative lamp is characterized in that it has a light source on the end face of the main body, and a shade is attached to the end of the rotating shaft.

Description of examples Next, embodiments of the present invention will be described with reference to the drawings.

1 to 3 show a first embodiment, in which a main body 1 has a built-in motor 2. FIG. The motor 2 is mounted by attaching an abbreviated mounting piece 3 to a substantially U-shaped yarn 4, and the top surface of the chassis 4 is a substantially cylindrical mounting piece 3 formed on the top of a substantially cylindrical cover 5. It is attached to the bottom of the recess 6 with screws or the like. The lower end of the approximately inverted V-shaped hanging tool 8 at the lower end of the chain 7 for hanging passes through the recess 6 and the chassis 4, respectively, and is hooked to the chassis 4. Power is supplied to the main body 1 by a cord 1o including an intermediate switch 9. 11 is a plug, and 12 is a heaton. A substantially circular end plate 1 is provided at the bottom end of the chassis 4.
3 is attached with screws etc., and the rotating shaft 14 of the motor 2
is an end plate 1 formed with an inner diameter slightly larger than its outer diameter.
3 protrudes from the hole 15. The rotating shaft 14 includes a shaft 16 protruding from the motor 2 and a screw 1 attached to this shaft 16.
The first joint 18 attached at 7, the second joint 19 attached by screwing to the end of this first joint 18, and the rod 21 attached to this second joint 19 with a 2° screw. , a nut 22 screwed near the end of this rod 21, washers 24 and 25 spaced apart via a cylindrical spacer 23, a spring washer 26, and the nut 2.
Consists of 7. An intervening body 28 made of a flexible material such as rubber is arranged on the end face of the washer 24, and the hole 30 at the lower end of the approximately spherical shade 29, which is divided into upper and lower parts, is fitted onto the outer periphery of the spacer 23. The hole edge of the hole 30 is the intervening body 2
8 and the washer 26, and the shade 29 is located between the rotary shaft 14 and the washer 26.
It is rotatably attached to the end of the rotating shaft 14. A decorative camp 31 made of a flexible material such as rubber is attached to the rotating shaft 1
It is attached to the outer end of 4 so as to be rotatable with respect to the rotating shaft 14.

The reason why the shade 29 is rotatably attached to the rotating shaft 14 is because it is loosely fastened between the washer 24 and the washer 25 through the interposition of the intervening body 28. and the washer 25, that is, the spacer 23
Of course, considering the length of the shade 29, the shade 29 can be rotatably attached. However, if the intervening body 28 is present, it is possible to effectively prevent the shade 29 from wobbling.

Since the decorative cap 31 has a screw thread at the end of the rotating shaft 14, it is pushed into the screw thread and is secured simply by friction, so that the decorative cap 31 is rotatably attached. light source 32
is provided on the end plate 13 of the main body 1 and is attached to the end plate 13 via a socket 33.

When the rotary decorative light according to this embodiment is powered,
When the light source 32 is turned on, the rotating shaft 14 is rotated by the motor 2. The light from the light source 32 is emitted to the outside from the star-shaped transparent part of the shade 29, and the star-shaped pattern projected on the wall surface etc. moves gently. axis 14
Since the displacement of the motor 2 is restricted by the hole 16 of the end plate 13, there is almost no risk of damaging the speed reduction mechanism or the like inside the motor 2. Reduction mechanisms usually use gears made of synthetic resin, which makes them susceptible to damage from impact, but as mentioned above, they are resistant to impact, so the risk of damage can be avoided. .

Next, even if rotational force is applied to the shade 29, the shade 2
9 is rotatable with respect to the rotating shaft 14, the shade 2
The motor 2 is protected because almost no rotational force acts on the rotating shaft 14 when the rotating shaft 9 simply rotates idly.

Furthermore, even if the decorative cap 31 is turned by hand, the motor 2 is protected because the decorative cap 31 is rotatable with respect to the rotating shaft 14 and almost no rotational force acts on the rotating shaft 14. will be accomplished.

Furthermore, the rotating shaft 14. That is, the first joint 1
8 and the second joint 19 are provided with flanges 18a and 19a formed with an outer diameter larger than the inner diameter of the hole 15 so as to be located above and below the hole 16, respectively, so that a vertical impact is applied to the shade 29. However, the motor 2 is still protected.

FIG. 4 and FIG. 5 show a second embodiment, in which a stand type rotary decorative light is constructed. In the figure, parts that are the same as those in the first embodiment are given the same reference numerals.

To explain the difference from the first embodiment, the chassis 4 is attached to a bottom plate 34 attached to the bottom of the cover 5 of the main body 1. A decorative ring 35 made of a flexible material such as rubber is attached to the bottom outer periphery of the cover 5. The end plate 13 and the cover 6 are fixed to each other by inserting a screw into a post 5a protruding from above the cover 5 and screwing it into the end plate 13. The rotating shaft 14 is provided with the spacer 23 of the first embodiment. Washer 2
5° spring washer 26. There is no nut 27, and the shade 29 is simply placed on the intervening body 28, whereby the shade 29 is rotatably attached to the rotating shaft 14. Regarding the protection of the motor 2, there is no difference from that in the first embodiment.

Effects of the Invention According to the rotary lighting lamp of the present invention detailed above, since the rotating shaft of the motor protrudes from the hole in the end face of the main body formed with an inner diameter slightly larger than the outer diameter, the rotating shaft Even if a lateral impact is applied to the shade attached to the motor, there will be almost no vibration of the rotating shaft, and therefore there is almost no risk of damage to the inside of the motor, especially the reduction mechanism, which will definitely prevent problems in actual use or transportation. It is something that can be resolved.
