Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a rotary decorative lamp whose sissade is rotated by a motor.

Conventional structure and its problems Conventionally, in rotary decorative lamps in which the sisade is rotated by a motor, a decorative camp is sometimes attached to the outside of the shade, but when a rotational force is applied to the decorative cap from the outside, the inside of the motor In particular, the reduction mechanism was prone to damage, which was inconvenient in actual use and 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 rotational force is applied to the decorative cap from the outside. According to the present invention, a motor is built into the main body, a rotating shaft of the motor projects from the main body, a light source is provided on the end face of the main body, a shade is attached to the end of the rotating shaft, and an external This constitutes a rotary decorative lamp characterized in that a decorative cap is rotatably attached to the end of the lamp.

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 attached to a substantially U-shaped chassis 4 via an abbreviated mounting piece 3, and the top surface of the chassis 4 is formed in a substantially cylindrical recess formed at the top of a substantially cylindrical cover 5. It is attached to the bottom of 6 with screws, etc. 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. The main body 1 has a cord 1 including an intermediate switch 9.
Powered by 0. 11 is a plug, and 12 is a heaton. A substantially circular end plate 13 is attached to the lower end of the chassis 4 with screws or the like, and the rotating shaft 14 of the motor 20 protrudes from a hole 15 in the end plate 13, which is formed to have an inner diameter slightly larger than its outer diameter. The rotating shaft 14 includes a shaft 16 protruding from the motor 2, a first bolt 18 attached to the shaft 16 with a screw 17, and a second bolt 18 screwed to the end of the first bolt 18. a rod 21 attached to this second joint 19 with a screw 20, a nut 22 screwed into the vicinity of the end of this loft 21, and a washer 2 spaced apart via a cylindrical spacer 23.
4, a washer 25, a spring washer 26, and a nut 27. An intervening body 28 made of a flexible material such as rubber is disposed on the end face of the washer 24, and a hole 30 at the lower end of the approximately spherical shade 29, which is divided into upper and lower parts, is connected to the spacer 23.
The edge of the hole 30 is positioned between the intervening body 28 and the washer 26 so as to fit on the outer periphery of the shaft 14 , and the shade 29 is attached to the end of the rotating shaft 14 so as to be rotatable with respect to the rotating shaft 14 . A decorative cap 31 made of a flexible material such as rubber is attached to the outer end of the rotating shaft 14 so as to be rotatable relative to the rotating shaft 14. The reason why the shade 29 is rotatably attached to the rotating shaft 14 is that it is loosely fastened between the washer 24 and the washer 26 through the intervention of the intervening body 28, but even without the intervening body 28, the washer It goes without saying that the shade 29 is rotatably mounted, considering the distance between the washer 24 and the washer 25, that is, the length of the spacer 23. 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 thread at the end of the rotating shaft 14,
It is simply pressed into the thread and held in place by friction, so it is rotatably mounted. The 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,
As the light source 32 lights up, 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. If a lateral impact is applied to the shade 29, it rotates. axis 14
Since the displacement of the motor 2 is restricted by the hole 15 of the end plate 13, there is almost no risk of damaging the deceleration mechanism or the like inside the motor 2. Reduction mechanisms usually use a lot of gears made of synthetic resin, so they are susceptible to damage from impact. be.

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
Since almost no rotational force acts on the rotating shaft 14 when the motor 9 idles, the motor 2 is protected.

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

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

FIGS. 4 and 5 show a second embodiment, in which a stand-type rotary decorative light is constructed. In the figure, parts that are the same as or corresponding to those in the first embodiment are given the same reference numerals. is installed. 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 post 5aK screw 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 25° Spring washer 26. Natsuto 27 is missing and Sade 29
is simply placed on the intervening body 28, and thereby 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 decorative lamp of the present invention detailed above, since the decorative cap is attached to the end of the rotating shaft of the motor so as to be rotatable with respect to the rotating shaft, rotational force is applied to the decorative cap from the outside. . For example, even if you accidentally turn it by hand, there is almost no rotational force acting on the rotating shaft, so the inside of the motor.

In particular, there is almost no risk of damage to the speed reduction mechanism, and problems in actual use or transportation can be reliably solved.
