DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative fan which can enhance a decorative effect by emitting light effectively.

[0002]

2. Description of the Related Art Some fans have a decorative fan that is used for purposes other than practical use, for example, a fan that emits light to enhance the decorative effect.

[0003] Examples of this type of fan include those in which light emitting diodes are attached to the periphery of the fan at predetermined intervals, and those in which the surface of the fan is coated with a luminous paint.

[0004] However, in the case where the light emitting diode is attached to the outer periphery of the fan, the surface of the fan cannot be illuminated. For example, the pattern designed on the surface of the fan cannot be illuminated effectively. The decoration effect is small only by shining in a dot shape.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a plan view showing an example of a fan to which the present invention is applied, and FIG. 2 is an enlarged cross-sectional view taken along line AA of FIG. As shown in FIG. 1, the fan 1 is configured by pulling out a handle 50 from the outer periphery of a substantially disk-shaped fan main body 10. Hereinafter, each component will be described.

The fan body 10 is formed by integrally molding a transparent synthetic resin (for example, acrylic resin) as a whole. The specific shape of the fan body 10 is a substantially disk-shaped main light emitting portion 1 inside.
1 and a ring-shaped outer peripheral portion 21 and the main light emitting portion 1
1 are connected by a plurality of connecting portions 26.

The main light emitting section 11 has a display section 13 on one side and a reflection section 23 on the other side. The display unit 13 has a planar shape, and a decorative unit 15 made of a decorative film is attached to a surface of the display unit 13. The decorating section 15 is formed in the shape of a blank character by printing so that light passes only from a necessary portion of the transparent film, or is configured by simply printing a pattern. Alternatively, the film constituting the decorating portion 15 may be an opaque film, and only the portion that becomes a blank character or a blank pattern may be cut out. In short, any printing format may be used as long as it is printed so that the decoration is effectively raised on the front side by irradiating light from the back side. In the drawing, for the sake of illustration, the decorative portion 15 (the reflecting member 2 described below) is shown.
5 is the same).

The entire surface of the reflecting portion 23 is a tapered surface. FIG. 3A shows the taper state extremely large compared to the actual state in order to clearly show the taper state. However, as shown in FIG. 2 and FIG.
It has a tapered surface that reduces the thickness from the root portion to which the handle 50 is attached toward the tip portion. That is, the display section 13 is formed flat (parallel to the light traveling direction), and the reflecting section 23 is formed slightly tapered (slightly oblique to the light traveling direction). In other words, the light emitted from the light emitting element 70 installed at the base portion to which the handle 50 is attached is
Is tapered so that its thickness decreases in the direction in which it advances toward the tip. A reflection member 25 made of white paper for reflection is attached to the reflection portion 23. The reflection member 25 may be of any other color as long as it reflects light, and the material may be another material such as a resin film, and a paint may be directly applied to the reflection portion 23 or vapor deposited. The reflective member 25 may be provided with a blank character so that light leaks from a part thereof, so that the reflective member 25 can be used as a reflective portion and at the same time as a display portion.

Further, between the main light emitting portion 11 and the outer peripheral portion 21,
A large number of openings 27 are provided between the connecting portions 26 by being connected by a plurality of connecting portions 26 that are curved in a wave shape.

Next, the handle 50 is cylindrical and has three button batteries 51 and one slide switch 53 inside.
And the three light emitting elements 70 are housed in a circuit-coupled manner. And the slide button 55 of the slide switch 53
Is turned on to turn the light emitting element 70 on and off. Each of the three light emitting elements 70 is installed in the vicinity of the portion of the handle 50 connected to the main light emitting portion 11, with the central one oriented in the axial direction of the handle 50 and the left and right ones oriented in the axis of the handle 50. It is installed so as to be inclined left and right in the plane of the main light emitting unit 11 with respect to the direction. That is, by changing the direction of the plurality of light emitting elements 70, each part of the main light emitting unit 11 is made to emit light uniformly. In this embodiment, a light emitting diode is used as the light emitting element 70, but a light emitting element having another structure may be used. Further, the number of the light emitting elements 70 can be changed as needed, and it is sufficient that the number is one or more.

Next, the operation of the fan 1 will be described.
The fan 1 is used, for example, as a gift for sales promotion, used in place of a penlight at a concert hall, or used as a fan for a Bon dance or a night stall. That is, when the slide switch 53 is turned on by operating the slide button 55 in a dark place, the three light emitting elements 70 are turned on, and light travels in the plane of the main light emitting section 11. Although this light travels substantially parallel to the surface of the display unit 13, most of the light is reflected on this opposite surface because the reflection unit 23 has a tapered surface, and travels toward the display unit 13 side. Therefore, most of the light is radiated from the entire surface of the display unit 13 to the outside,
The decoration unit 15 is effectively illuminated.

A part of the light is introduced from the outer periphery of the main light emitting portion 11 to the outer peripheral portion 21 through the connecting portion 26,
And the outer peripheral portion 21 is also illuminated. However, since the amount of light introduced into them is not large, they cannot be illuminated as brightly as the main light emitting portion 11.

Since the light quantity of the light emitting element 70 is not so large, when the entire fan main body 10 is formed in a flat plate shape and the whole surface is illuminated brightly, a portion close to the light emitting element 70 can be illuminated brightly. The portion near the outer peripheral edge of the fan body 10 away from 70 becomes darker,
The unevenness of light becomes large and hinders the decorativeness.
0 may be used as long as it is small). Therefore, in the present embodiment, only the main light emitting portion 11 having a small area in the fan main body 10 is brightly illuminated, and the decoration made in that portion is effectively raised, and the other portions are relatively dark. However, it was designed to further enhance the decoration effect by emitting light.

In some cases, only the main light-emitting portion 11 of the fan body 10 is made of a light-transmitting material, and the other portions are made of a light-transmitting material, or a light-transmitting paint is used. May be applied so that only the main light emitting section 11 emits light.

Further, the main light emitting portion 11 is provided at a position closer to the handle 50 than the center of the fan main body 10 as in this embodiment because the light emitting element 70 is provided at the handle 50 portion. , The main light emitting portion 11 as much as possible
This is for positioning at a portion close to zero.

In the above embodiment, the main light emitting section 11
The outer portion 21 is connected to the outer peripheral portion 21 by the connecting portion 26 to form the opening 2.
7 is provided for the following three reasons. That is, one is for drafting. Since the fan 1 is for decoration, it is not so effective for sending wind. Since the fan body 10 is made of molded resin, it does not bend so much. When the fan body is turned upside down, there is a possibility that wind pressure may cause a problem such as cracking of the fan body 10 or the portion between the fan body 10 and the handle 50. is there. Therefore, an opening 27 for venting is provided. The second is opening 27
Is provided to reduce the weight of the fan 1. Third, the provision of the opening 27 allows the connecting portion 26 to have various shapes to enhance its decorativeness.

In the above embodiment, one surface of the main light emitting section 11 (display section 13) is mainly illuminated. However, the opposite reflecting section 23 may be illuminated as a display section. That is, as shown in FIG. 3B, both the display unit 13 and the reflection unit 23 are formed in a tapered shape, and the decoration and reflection members 15 and 25 are provided on both surfaces thereof. Light reflected from different surfaces enters the two surfaces 13 and 23, and both surfaces are evenly illuminated.

While the embodiments of the present invention have been described in detail, the present invention can be variously modified within the scope of the claims and the technical idea disclosed in the specification and the drawings. That is, for example, the following modifications are also possible. It goes without saying that the fan may have any shape and structure as long as the handle is pulled out from the outer periphery of the fan body.

The main body of the fan does not necessarily have to be transparent, but it is essential that it be formed of a light-transmitting material.

The position where the light-emitting element is mounted is not limited to the handle, but it is essential that the light-emitting element be mounted at a position where light is introduced into the fan body.

In the case where both sides are used as the display unit, various use methods are conceivable, such as displaying the singer's face on one side and the singer's name on the other side.

The case of the handle 50 may be made transparent so that the inside can be seen through.

A timer may be housed inside the fan 1 and turned on when the switch is turned on and turned off after a lapse of a predetermined time, or may be repeatedly turned on and off when the switch is turned on.

A sound may be generated together with light by incorporating a speaker.

Further, as shown in FIG. 4, by providing reflection portions 18 and 18 which are notched in a slit shape for reflecting the light emitted from the light emitting element 70 inside the main light emitting portion 11, the light is weakened. A configuration may be adopted in which light is forcibly guided to a part or the like.

In some cases, the entire fan main body 10 may be configured as the main light emitting section 11.

[0030]

As described in detail above, the present invention has the following excellent effects. The main body of the fan is made of a translucent material, and the light-emitting element that emits light by introducing light into the fan body is attached. Can provide a large fan for decoration.

When the main light emitting portion is provided in a part of the fan main body, the main light emitting portion can be effectively illuminated, and the decorative effect can be increased with a small amount of light.

Since at least one of the two surfaces of the main light emitting portion is a reflecting portion having a tapered surface, the light introduced into the main light emitting portion is reflected by the reflecting portion and effectively illuminates the opposite surface. Can be put out.

Since the opening is provided between the main light emitting portion and the peripheral portion around the main light emitting portion, air can be vented, the weight of the fan can be reduced, and its decorativeness can be enhanced.

Since the handle is attached to the outer periphery of the main light emitting section and the light emitting element is attached near the portion connected to the main light emitting section of the handle, the light emitting element can be easily installed near the outer periphery of the main light emitting section, and the waste can be effectively achieved. Light can be introduced into the main light-emitting portion.
In particular, it is preferable that the main light emitting portion is provided at a position closer to the handle than the center of the fan main body, since the connection between the handle and the main light emitting portion is facilitated.
