Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap for preventing a human body from being affected when a mobile phone or the like is used.

[0002]

2. Description of the Related Art In recent years, electric equipment has become widespread based on technological advances. In everyday life, there are many devices such as OA devices at work and microwave ovens and mobile phones at home. Such a device emits an electromagnetic wave when it is used, and if this electromagnetic wave keeps bathing innocently,
It causes abnormalities in the body.

[0003]

Conventionally, televisions and OA have been used to prevent electromagnetic waves in daily life.
Shield screen to be attached to the device display,
There is a shield apron for magnetic shielding. For these, the shield screen is dedicated to the screen of a television or the like, and the shield apron is intended to protect the fetus against the body of the pregnant woman.

On the other hand, the mobile phone is considered to have the greatest effect on the human body. That is, since this type of device is used close to the mouth and ears, there is a problem in that it continues to receive electromagnetic waves in a place extremely close to the eyes and head. Cellular phones use microwaves of 800 to 900 megahertz, and the transmission output is weak at 0.6 to 1 watt, but it can be said that there is a certain biological effect in the vicinity of the site, centering on the thermal effect.
Similar problems have been pointed out for transceivers that respond at close range, and these have a high risk of cataracts, and research into their relationship with brain tumors has been started.

However, the trend of the times is toward the direction of cordless communication, and the types thereof are becoming more and more diversified.

[0006]

According to the present invention, a cap is formed of a conductive material or a member on which a conductive layer is formed so as not to be affected by electromagnetic waves existing in daily life. The shield cap is characterized in that it further has an ear pad and a brim formed as the shape of the cap.

The conductive material may be a metal steel material, and the conductive layer is a woven fabric in which a fibrous conductive material such as carbon fiber is woven, a resin material such as FRP containing copper foil, electroless plating after molding, A member that is electrolytically plated and a member that is coated with a conductive paint after molding may be used.

[0008]

By covering the head with a cap made of a conductive member, electromagnetic waves are absorbed by the member and the head can be protected. Also, by forming an ear pad,
When using a mobile phone or the like, the ear portion can be covered and protected, and by forming the collar, the eyes and the head can be protected from the upper side and the front side.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the shape of an embodiment of the present invention will be described with reference to the drawings.

1 to 3 show an embodiment of a shield cap utilizing the present invention. The cap 1 is formed of a hard material such as steel or resin molding, and a main body 2 that covers a human head is formed in a substantially hemispherical shape.

An ear pad 3 is formed on a part of the circumferential end of the main body 2 so as to extend the curved surface of the main body 2 substantially. The ear pad 3 is formed in a shape that covers the ears on the side of the human head when the body 2 is put on the human head. As a result, when the cap 1 is used when using a communication device such as a mobile phone, it is possible to effectively block electromagnetic waves from the communication device as shown in FIG. The earpiece 3 is provided with a small number of small holes 4 so that electromagnetic waves can be effectively shielded while using the communication device, while not hindering communication.

A collar 5 is formed on a part of the circumferential end of the main body 2 of the cap 1 so as to stand upright from the curved surface of the main body 2 in addition to the earpiece 3. The collar 5 is formed in such a shape that when the body 2 is put on a human head, the collar 5 projects above the eyes in front of the human head. That is, when the eyes are shielded like the ear pads 3, the eyes hardly function as human senses, do not interfere with the visual field, and have a shape effective for preventing electromagnetic waves in the environment. As a result, the collar 5 projects like an eaves on the eyes, so it is possible to block the electromagnetic waves from the upper side, and it is also possible to intentionally tilt the collar 5 to block the electromagnetic waves from the front. Is.

Regarding the shape that protects the eyes, a collar 5 is shown in the drawing.
Alternatively, a conductive mesh may be formed by using a thread-like member such as a wire or carbon fiber described later, and the shape may be formed so as to hang it in front of the eyes, although not shown. As a result of this mesh structure, it is possible to have a field of view while blocking electromagnetic waves.

Next, members that can be used in the shield cap utilizing the present invention will be described.

First, as a member forming the shield cap, a case where a conductive material having conductivity is used,
In some cases, a non-conductive member provided with a conductive layer is used.

As the conductive material, a metal steel material such as stainless steel, aluminum or titanium, or a conductive resin such as a polymer containing polypyrrole carbon can be used. By using a member that has direct conductivity, processing is simple and
Metallic steel such as stainless steel has excellent conductivity and strength, and does not require complicated surface treatment. Also, aluminum and titanium are lightweight even for metallic steel materials. Of course, the conductive resin is lighter in weight than the metal steel material, and weatherproof coating may be easily performed after the molding.

The conductive layer provided on the non-conductive member is a woven fabric in which a fibrous conductive material such as carbon fiber is woven, a resin material such as FRP containing copper foil, electroless plating or electrolytic plating after molding. It is possible to use a member that has been subjected to the above treatment, or a member that has been coated with a conductive paint after molding.

When a woven fabric in which a fibrous conductive material such as carbon fiber is woven is used, it does not have strength as a cap, but it can be woven into a flexible shape or cut and joined depending on the purpose. Therefore, the body shape of the cap may be a pointed hat depending on the preference. And in this case,
It is possible to fold the cap.

In the case of a resin material such as FRP containing copper foil, the cap can be made lighter and stronger than metal steel material, and if the copper foil is uniformly arranged and connected at the time of processing, the electromagnetic wave shielding performance is also improved. It is comparable to metal materials.

A member that has been electrolessly plated or electrolytically plated after molding or a member that has been coated with a conductive paint after molding can be made into a lightweight and durable cap by selecting a resin material. Is also comparable to metal materials.

Next, as an example of the use of the shield cap of the present invention, a case will be described in which the electromagnetic waves of a mobile phone are used so as to be blocked more effectively during use.

In FIG. 5, the conductor 7 is drawn out from the shield cap 1 and connected to the mobile phone 8. A pin 9 is formed at the tip of the conducting wire 7, and a jack 10 for holding the pin 9 is provided on the mobile phone 8. The jack 10 is connected to the ground of an internal circuit (not shown) in the mobile phone 8. That is, the shield cap 1 is connected to the ground in the mobile phone 8 through the conductor 7, and the induced current due to the absorbed electromagnetic wave can be flown to the ground, so that the electromagnetic wave is stronger than simply wearing the shield cap 1. It becomes possible to cut off.

The user of the mobile phone 8 wears the shield cap 1 immediately before making a call, inserts the pin 9 at the tip of the lead wire 7 into the jack 10 of the mobile phone 8, and starts the call. Even if the mobile phone 8 is brought close to the ear in that state, the electromagnetic waves to the head of the user are strongly blocked.

Of course, the grounding destination of the conductor 7 from the shield cap 1 is not limited to the mobile phone, but may be the grounding of other devices, or so-called grounding.

[0025]

As described above, in the present invention, by covering the head with the cap using the conductive member, the electromagnetic wave is absorbed by the member and the head can be protected. Further, by forming the ear pad, the ear portion can be covered and protected when the mobile phone or the like is used, and by forming the brim, the eyes and the head can be protected from the upper side and the front side.
