Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lightning garment for outdoor activities for protecting the body from lightning strikes.

[0002]

2. Description of the Related Art As a conventional lightning protection garment, for example, the one disclosed in Japanese Utility Model Laid-Open No. 59-117616 is known. That is, the conductive wires are distributed in a mesh shape on the integrated conductive garment that covers the whole body, and the conductive wires are connected to one lumped wire. This bundled wire is attached to a grounding rod via a grounding wire and is buried in the ground.

[0003]

However, since the conventional lightning protection clothing has an integral structure that covers the whole body, there is a problem that the movement of the body is restricted and it is cramped. Also, since the clothes are connected to the ground via the ground wire and ground rod,
There was also a problem that the range of action of the wearer was limited to the length of the ground wire even at the maximum.

The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to provide a comfortable wearing feeling, easy movement of the body, and freedom of action without limiting the range of action. To provide lightning protection.

[0005]

In order to solve the above-mentioned problems, the lightning-resistant garment of the present invention is constructed by dividing it into a plurality of clothing pieces and footwear that cover different parts of the body, and each clothing piece and footwear are made conductive. It is characterized in that it is formed of a conductive material and that the clothing pieces are connected by a conductive connecting member.

[0006]

According to the above-mentioned solution means, since the lightning protection garment is divided into a plurality of garment pieces and footwear as in the case of normal garment, the movement of each part of the body is not restricted and the wearing feeling is improved. Moreover,
Since each clothing piece and the footwear are connected by the conductive connecting member, the lightning current is surely induced from the clothing piece to the other clothing piece and discharged to the ground to prevent the current from flowing into the body. Therefore, it is not necessary to provide a grounding rod, and the wearer's freedom of action is secured.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a lightning protection garment for climbing, and FIG. 2 shows a lightning protection garment for construction. The lightning protection suit 1 includes a plurality of clothes pieces 2 to 6 covering different parts of the body and shoes 7 as footwear.
It is divided into two parts. In the figure, 2 is an upper garment that covers the upper body, 3 is a lower garment that covers the lower body, 4 is a hat that covers the head,
Reference numeral 5 is gloves for covering hands, and 6 and 7 are socks and shoes for covering legs.

The clothing pieces 2 to 6 and the shoe 7 are made of a conductive material. As the conductive material, a conductive cloth, a conductive sheet, a conductive non-woven fabric or the like is used. As the conductive cloth, metal, cloth woven only with conductive fibers such as carbon, cloth mixed with conductive fibers and natural fibers or synthetic fibers, as conductive sheet, carbon fibers or carbon particles were kneaded Examples of the conductive sheet and the conductive non-woven fabric include non-woven fabric mixed with a conductive foil.

The clothing pieces 2 to 6 and the shoe 7 are connected by conductive connecting members 9 to 13. That is, upper 2 and lower 3
Is a connecting member 9, and the upper garment 2 and the hat 4 are connecting members 10
The upper garment 2 and the glove 5 are the connecting members 11, the lower garment 3 and the socks 6 are the connecting members 12, and the socks 6 and the shoes 7 are the connecting members 13.
Are connected respectively. In addition, as shown in FIG.
It is preferable to connect the upper garment 2 and the belt 8 and the belt 8 and the lower garment 3 by separate connecting members 9.

As the connecting members 9 to 13, ribbons made of conductive fibers having metal hook buttons at both ends, conductive fasteners, conductive surface fasteners (velcro tapes), metal snaps, binding made of conductive fibers. For example, a string can be used.

Here, from the tip of the lightning proof 1 to the other tip, for example, from the hat 4 to the shoe 7, from the hat 4 to the glove 5, from the glove 5 to the lower edge of the upper garment 2, from the glove 5 to the shoe 7. The resistance may be 50 mΩ or less and the inductance may be 1 μH or less. Generally, the lightning strike current is said to be several kA to several hundred kA, but if the current of 100 kA is set to 100 V or less, the electrical resistance of the lightning proof clothing 1 needs to be 1 mΩ. Since a lightning current exceeding 100 kA is rare, if the minimum value of the lightning current is 2 kA, the resistance is 50 m.
Ω or less, and the inductance is preferably 1 μH or less.

Further, when cloth is used as the conductive material of the lightning protection clothing 1, as shown in FIG. 5, the texture is such that the conductive paths b of the fibrils a are oblique to the overall current direction c. Should be formed in a diamond shape. By doing so, the local current directions are opposite to each other, so that it is possible to cancel the magnetic fields and reduce the inductance generated in the overall current direction c.

According to the climbing and working lightning protection garment 1 configured as described above, since the clothing pieces 2 to 6 and the shoe 7 are connected by the conductive connecting members 9 to 13, the lightning currents are different from each other. It is discharged to the ground through the clothing pieces 2 and the shoes 7, and the current flow to the body is suppressed. For example, in FIG.
If a lightning strike strikes the glove 5 as shown by the arrow.
Is discharged through the upper garment 2, the lower garment 3, the socks 6, and the shoes 7 to the ground. Therefore, even if the person is directly hit by a lightning strike, the damage to the body can be greatly reduced. Further, since the lightning-resistant clothing 1 is configured by being divided into a plurality of clothing pieces 2 to 6 and shoes 7 like normal clothing, the movement of each part of the body is not restricted,
Physical movement is easy and wearability is improved. Moreover, unlike the conventional case, since the grounding rod is not provided, the wearer's freedom of action can be secured.

FIG. 3 shows a piece of clothing for covering the face and the back of the head. Here, the net 17 which is made of a conductive material and whose visibility is secured has the hat 4 and the upper garment via the conductive connecting members 18 and 19. 2 is electrically connected. In this case, it is possible to prevent lightning from hitting the hearing aid, glasses, false teeth and the like. The net 17 may be integrated with the hat 4.

FIG. 4 shows a garment piece for covering the eyes, that is, spectacles 21. Here, a spectacle frame 21a made of metal is connected to the hat 4 by a conductive connecting member 22. In addition, the present invention is not limited to the above embodiment,
The configurations of the respective units may be appropriately modified and embodied as follows, for example, without departing from the spirit of the present invention. (A) Applying the lightning protection garment of the present invention to lightning protection garment for various outdoor activities such as agricultural work, golf, and fishing. (B) The clothing pieces 2 to 6 and the shoe 7 should be appropriately designed such as shape, pattern, and color according to the application. (C) Use sandals as footwear.

[0016]

As described in detail above, according to the present invention, since a plurality of clothes pieces made of a conductive material and footwear are connected by a conductive connecting member, the wearing feeling is good and the movement of the body is good. It has an excellent effect that it is easy and, moreover, it can act freely without restricting the range of action, and with this, the damage caused by lightning strike can be reduced.
