Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotating lantern mainly used as a sacred lantern and a lantern.

[0002]

2. Description of the Related Art FIG. 7 shows the structure of the main part of a commonly used lantern. As shown in the figure, the frame 1 has a structure in which a semi-transparent sheet 3 made of Japanese paper or the like is stretched over a cage-shaped frame 2. The frame 1 may be a lantern without the frame 2. A light-emitting body 4 is provided inside the frame body 1. As the light-emitting body 4, an incandescent light bulb in which a filament is contained in a glass bulb 5 is usually used.

Between the light emitting body 4 and the frame body 1, a pattern is formed on a peripheral wall 6 having a light transmitting property, and a rotary cylinder 8 having a windmill 7 attached to an upper end surface thereof is provided. The rotary cylinder 8 is rotatably supported by a support tool 50 provided on the light-emitting body 4. The support tool 50 is provided with a shaft 52 that has a tip end engaged with a recess 9 formed in the center of the wind turbine 7 at the upper part of a holding ring 51 that holds the glass ball 5.

In the rotating lantern as described above, the rotating cylinder 8 is rotated by the ascending air current generated by the heat generation of the light emitting body 4 colliding with the wind turbine 7, and the pattern of the rotating cylinder 8 is rotated and the frame 1 of the frame 1 is rotated. It is projected on the sheet 3. At this time, in order to rotate the rotary cylinder 8 smoothly, the shaft 52 must be set vertically.

[0005]

However, in the rotating lantern as described above, since the position of the support tool 50 with respect to the light-emitting body 4 is not fixed, it is difficult to set the shaft 52 vertically, and the rotation tube 8 of the rotary cylinder 8 is difficult to set. The balance may be lost and the rotary cylinder 8 may not rotate smoothly.

Further, the holding ring 51 of the supporting member 50 is attached to the light emitting member 4
When the glass ball 5 was fitted, a large force was applied to the glass ball 5, and there was a risk that the glass ball 5 would be damaged.

Further, when the frame body 1 falls, the peripheral wall 6 of the rotary cylinder 8 comes into contact with the light emitting body 4 which continues to light up, and the peripheral wall 6 and the sheet 3 of the frame body 1 are scorched, which may cause a fire. .

[0008] Therefore, an object of the present invention is to provide a rotating lantern in which the rotary cylinder rotates smoothly and which is excellent in safety during assembly and overturning.

[0009]

In order to solve the above-mentioned problems, the present invention provides a light-emitting body inside a frame body having a semitransparent sheet stretched on the outer periphery thereof, and between the light-emitting body and the frame body. , A pattern is formed on a light-transmitting peripheral wall, and a rotating cylinder having a windmill attached to its upper end surface is rotatably provided, and an ascending air current generated by heat generation of a light emitter collides with the windmill to rotate the rotating cylinder. In a rotating lantern projecting a pattern of a rotating cylinder onto a sheet of a frame while rotating, a bracket whose upper end is located above the center of the light emitter is erected on the bottom of the frame, and the upper end of the bracket is A shaft extending in the vertical direction is provided in either one of the portion and the center of the wind turbine, and a recess is formed in the other, and the shaft is engaged with the recess to support the rotary cylinder.

Further, a structure is adopted in which a sensor switch for turning off the light-emitting body is provided when the frame body falls.

[0011]

In the rotating lantern constructed as described above, the rotating cylinder is supported in a well-balanced manner by the bracket erected on the bottom of the frame.

Further, it is not necessary to fit a support to the luminous body, and there is no risk of damaging the luminous body during assembly.

Further, since the light-emitting body is turned off when it falls,
The peripheral wall of the rotating cylinder and the sheet of the frame will not burn.

[0014]

Embodiments of the present invention will be described below with reference to the accompanying drawings. It should be noted that the same parts as those of the conventional example shown in FIG.

As shown in FIGS. 1 to 3, a bottom cover 10 is fitted in the bottom opening of the frame body 1, and the frame body 1 is supported by the legs 11 via the bottom cover 10. A cylindrical collar 12 is provided on the upper surface of the bottom lid 10.

On the other hand, the rotary cylinder 8 is supported by a bracket 20 which is detachably attached to the bottom cover 10. In this bracket 20, a vertical rod 22 is vertically provided on a bottom ring 21, and the bottom ring 21 is provided on an upper end of the vertical rod 22 via a bent portion 23.
The horizontal rods 24 extending in the direction of the center of the
4, a shaft 27 parallel to the vertical rod 22 is continuously provided via a bent portion 25 and a spring 26, the bottom ring 21 is fitted inside the collar 12, and the upper end of the shaft 27 is a windmill. It engages with the recess 9 of 7.

A sensor switch 30 is attached to the lower surface of the bottom cover 10. This sensor switch 30 is shown in FIG.
As shown in FIG. 3, a case 3 having a pair of electrodes 31, 31
2 is provided with a container 34 made of a conductor in which a small amount of mercury 33 is sealed, a pin 35 connected to one end of one electrode 31 is projected into the container 34, and the other electrode 31 is connected to the container 3
4, the pin 35 is immersed in the mercury 33 in a horizontal state so that both electrodes 31 are electrically connected and tilted by a predetermined angle or more, the pin 35 is exposed from the mercury 33 as shown in FIG. Thus, the power supply between the electrodes 31 is cut off.

In the rotating lantern as described above, the bracket 2
By simply fitting the bottom ring 21 of 0 inside the collar 12,
7 can be easily set vertically. Further, since it is not necessary to fit a support tool to the glass ball 5 during assembly, there is no risk of damaging the glass ball 5.

Further, since the light-emitting body 4 is turned off when it falls, the heat generation of the light-emitting body 4 is stopped and the peripheral wall 6 of the rotary cylinder 8 and the sheet 3 of the frame 1 are not burnt.

In addition, when an impact force is applied to the frame 1, the shock transmitted to the rotary cylinder 8 is mitigated by the spring 26, so that the vibration of the rotary cylinder 8 is suppressed.

As shown in FIG. 6, the bracket 20
A recess 40 is provided at the upper end of the rotary cylinder 8 by receiving a shaft 41 hanging from the center of the wind turbine 7 at the recess 40.
May be supported.

[0022]

As described above, according to the present invention, since the rotary cylinder is supported in a balanced manner by the bracket erected on the bottom of the frame body, the rotary cylinder rotates smoothly.

Further, it is not necessary to fit a support to the luminous body, and there is no risk of damaging the luminous body during assembly.

Furthermore, since the light-emitting body is turned off when the frame falls, the peripheral wall of the rotary cylinder and the sheet of the frame are not burnt, and a fire is prevented.
