JPH0832278A - Head shield - Google Patents

Abstract

PURPOSE:To obtain a head shield with which even a person, other than an expert, can use a portable radio telephone in safety by setting the head shield between the head part and the transmission antenna of the portable radio telephone transmitting a radio wave within a specified distance from the head part. CONSTITUTION:The radio wave shield 200 made of aluminum foil is set between the head part and the transmission antenna of a portable radio wave telephone transmitting a radio wave within 50 cm from the head part. The shield 200 is bonded to the inside of a cap 201 and intensively protecting the upper part 201a of ear opposing the antenna directly. This structure protects the head part against direct attack of radio wave radiated within a point-blank range thus protecting the head part of a user against the danger of tumor, or the like.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is necessary for safely using a portable radio telephone.

[0002]

2. Description of the Related Art In the past, radio transmitters were handled only by professional engineers, so the danger of being exposed to radio waves at close range was well recognized. Dangerous acts such as standing for a short time have been voluntarily avoided, but due to the widespread use of wireless telephones, it has become possible for someone other than an expert to handle the transmitter. There is a risk of dangerous usage such as being in close contact with and being used for a long time.

[0003]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems and allows a person other than an expert to safely use a portable radio telephone.

[0004]

By installing a radio wave shield device between the transmitting antenna and the head of a portable radio telephone, the risk of damage to the head due to transmitted radio waves is prevented.

[0005]

Since the present invention is configured as described above, radio waves emitted from a close range of the head are prevented from directly hitting the head, and a tumor for the head of a user of a radio telephone is prevented. It is possible to reduce the risk of occurrence, etc., and effectively prevent it.

04 is glued. The wig is generally used when the self hair is insufficient, but it can also be used for hair pis whose main purpose is to save the labor of hair styling. In this case, security is the main purpose, and wearing is an expression of intelligence, so it is not necessary to make the structure inconspicuous.

Reference numeral 201 in FIG. 2 denotes a cap, to which the radio wave shield device 200 of the present invention made of aluminum foil is adhesively bonded. In particular, the upper part of the ear facing the antenna directly
It protects intensively like a.

In the cap 301 shown in FIG. 3, the radio wave shield device 300 of the present invention has a spherical portion 300a outside the cap 300b.
As described above, it is extended into the collar portion 302 and is also electrically joined to a metal eyelet 303 provided near the center of the collar portion. When transmitting from a mobile phone, rotate the hat about 90 degrees, project the antenna upward from the eyelet hole 303, and use the ground contact part of the transmitter (not shown) provided at the base of the antenna in contact with the eyelet. To do.

In the cap 401 having a brim all around in FIG. 4, since the eyelet 402 can be installed on the upper part of the ear, it is not necessary to rotate the cap.

FIG. 5 is a cross-sectional view showing an embodiment in which a part of the radiotelephone is incorporated in the middle folding cap, and the drawing is a rear view of the central part of the cap cut left and right. The radio wave shield device 500 of the present invention is connected to the inside of the cap 501 by a plurality of detachable vent eyelets 502. Therefore, the hat can be replaced. Reference numeral 503 denotes an antenna column provided on 500, and an antenna 504 that is long in the front-rear direction in the drawing is provided at the upper end of 503 along the ridge of the hat. Fifty
Reference numeral 5 denotes a power amplifier unit of a wireless telephone including a power supply battery, which is connected to a remaining portion of the telephone (not shown) such as an earphone, a microphone, a push button, and a preamplifier unit via a connector 506. Reference numeral 507 is a calling bell.

FIG. 6 is an example in which the radio wave shield device of the present invention is provided on the radio side, and the figure is a side view showing a state when not in use. The radio wave shield device 600 of the present invention comprises a plurality of fan-shaped plates, the main part 600a of which is rotated around the axis of the disc-shaped earphone between the telephone body 601 and the disc-shaped earphone 602 connected to the telephone body 601. It is supported freely. Reference numeral 603 is an antenna, 604 is a microphone, and 605 is a selection push button.

FIG. 7 is a front view showing a state in which the fan is opened upward because the telephone is used. Reference numerals 600b and 600c and below are divided fan-shaped members, and the fan-shaped members are connected by a mechanism (not shown) similar to the reflector of the photographic flash bulb. In addition, a fan made of metal bone covered with a conductive cloth may be used.

FIG. 8 is an example in which an umbrella type radio wave shield device is provided, and the figure is a side view showing a state in use. Reference numeral 701 denotes a main body of the wireless telephone, and the lower end of the column 702 is rotatably supported by the main body 701 by a pin 703 and is electrically grounded to the main body 701. An antenna 704 insulated from 702 is coupled to a portion of the upper end of the pillar 702 that corresponds to a ridge of the umbrella, and the antenna cable 405 is connected to the pillar 70.
2 through the hole 706 to the outside of the pillar to reach the main body. Reference numeral 700 denotes a radio wave shield device according to the present invention, which has a structure similar to that of an umbrella bone and is arranged around a support column 702.
A cloth woven of conductive fibers may be put on the upper part of 0 like the umbrella. The inner end of 700 is rotatably supported by the upper end of the column 702, the upper end of the inner bone 707 is rotatably supported by 700, and the lower end is rotatably supported by the sleeve 708, and the lower end of the sleeve 708 and the upper end of the claw 709 are rotatably supported. The vertical movement is restricted by the pin 710. When not in use, the claw 709 is pushed to close the umbrella, and then it is rotated 180 degrees clockwise around the pin 703 and stored at the position of 702a.

In a mobile phone, the antenna, the earphone and the microphone are generally on the same line as shown in FIGS. 6 and 7,
On the other hand, since the human mouth is located in front of the ears, the telephone is tilted backward and used, and therefore 201a in FIG. This relationship differs depending on the model of the phone, so it is desirable to enter the applicable model on the hat.

[0015]

Since the present invention is configured as described above, radio waves emitted from a close range of the head are prevented from hitting the head directly, and the head of the user of the wireless telephone is prevented. It is possible to prevent the risk of tumor development.
