Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blade-proof material which is excellent in flexibility while maintaining blade-proofness, and a comfortable blade-proof garment which emphasizes wearability and mobility.

[0002]

2. Description of the Related Art Conventionally, there are blade-proof vests in which the whole body is made of one plate, and those in which a plurality of metal plates or plastic plates are used as they are, but they are hard and inferior in mobility and wearable. It was like a police officer hesitant to wear it at all times because it was bad. In addition to these,
No. 5-24090, a protector for blades, in which a plurality of metal plates are stacked on one piece of fabric and fastened with a screw, and bulletproof, as proposed in Japanese Utility Model Laid-Open No. 59-144399. It has been proposed to sew a bag in which the material for use is inserted into another cloth and sew it at the upper end so as to hang it on top of each other so that the bag is armored.

[0003]

However, in the prior art, the former one is fixed with screws and cannot be bent, and thus lacks in wearability.
The latter is simply hung and made into an armor, so you can easily pierce it with a knife from the bottom,
And it was something that could easily be penetrated.

In any case, while maintaining the blade-proof property,
There is no technology that focuses on flexibility and mobility, especially wearability and comfort.

In view of the drawbacks of the prior art, the present invention is to provide a blade-proof material and blade-proof garment which are excellent in motility, are comfortable to wear, and have excellent blade-proof property.

[0006]

The present invention employs the following means to achieve the above object. That is, the blade of the present invention is characterized in that the blade of at least one selected from a metal plate and a plastic plate is covered with a cloth. The garment is characterized in that at least the waistline is composed of such a blade member.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention focuses on the actual situation in which conventional blade-proof clothes, particularly blade-jackets, are stiff and hard to move when running or crouching, and are unable to move freely. It was done. That is, the present invention has been earnestly studied to provide a comfortable and excellent motility and wearability, and also excellent in blade-proof property. As a result, the blade plate is covered with a cloth, and this cloth is sewn. It has been clarified that a blade-proof material excellent in blade-proof property and flexibility, that is, movability can be provided by constructing clothes and a vest and combining the blade-proof plates.

That is, the blade of the present invention adopts a structure in which a plurality of blades made of at least one selected from a metal plate and a plastic plate are covered with a cloth. As a structure of such a coating, for example, in a plan view, adjacent blade-proof plates overlap each other, three blade-proof plates are arranged in a convex or concave shape, and the blade-proof plates are roof tiles. It is possible to employ a structure in which the elements are arranged in a shape. The term “overlapping structure” as used herein means that the blade-preventing plates are arranged so as to be displaced by the overlapping width.

In such a covering structure, each of the blade plates is independently covered with the cloth, which is further covered with another cloth. That is, in the present invention, the blade plates are overlapped in the coated fabric without a gap, that is, it is necessary to avoid forming a gap such that a cutting tool can penetrate, which is satisfied. It is important that it is a coating. Therefore,
Furthermore, a structure in which a plurality of the blade plates are arranged one by one such that the end portions thereof are superposed, and at least one end of the blade plate, for example, at least each upper end portion is joined to the cloth Alternatively, the blade-preventing plate may be sandwiched between two cloths.

In the case of connecting with the above-mentioned overlapping structure, the blade plate to be inserted into the blade material to increase flexibility is
It is preferable to match the height in the horizontal direction, and in order to prevent the thickness of the overlapped portion from increasing in the vertical direction, the width of the overlapped portion is preferably shifted by 1 cm for mounting. It is good to change the size of the blade. In addition, if you keep overlapping vertically and horizontally without overlapping, the thickness of the overlapping part will be 4 times the thickness of the blade material, but if you overlap it by shifting, it will be 3 times and 25% thinner You can Furthermore, in order to further control the thickness of the overlapping portion, it is preferable that the shape of the blade plate to be used is substantially square.
That is, generally, a shape in which at least one of the four corners is missing, a quadrangular plate with rounded end faces, and a quadrangle shape with a curved part close to the base of the arm only in the side part are The bulkiness can be controlled, and a thin product with excellent mobility can be provided. The width of the overlapping portion of the blade plate is 1 to 1.5 cm, preferably 1 to 1.2 cm. That is, if it is less than 1 cm, it is dangerous for a knife to enter from between the plates, and if it exceeds 1.5 cm, it tends to be heavy and hard and the motility tends to be impaired. Further, in order to prevent the blade from entering through the gap between the overlapping portions of the blade plate, it is also preferable to take measures to prevent slipping, such as making a hole in the blade plate to make it uneven.

The cloth of the present invention and the blade plate may be joined by adhesion, but preferably by sewing. By adjusting the length of the sewing thread, the motility can be freely changed from a considerably large degree to a delicate range. Because it can be adjusted to.

The material forming the blade plate is selected from a metal plate and a plastic plate. Examples of the metal plate include stainless steel plate, aluminum alloy, pure titanium,
At least one selected from titanium alloys is used, but stainless steel plates and aluminum alloys are preferably used in view of performance, raw materials, and processing cost. These are examples of suitable metals, but any metal that is rigid and tough may be used.

The plastic plate is preferably a single plate such as a polycarbonate plate, a nylon 6 / glass mixed plate, a polyamide-imide plate or a laminated plate of these, and a light and strong polyamide-imide plate is the most excellent. Of course, a laminated plate of a metal plate and a plastic plate is also preferably used. These are only examples, and other materials may be used, and a plate provided with a vent hole and a non-slip member for stopping a blade can also be used. Further, as the cloth, at least one selected from woven fabric, knitted fabric and non-woven fabric can be used. These fabrics may be used alone or in combination with each other. In particular, a cloth having a mesh structure is preferable in terms of breathability and stretchability. As the cloth of the present invention,
As described above, a material having elasticity, preferably elasticity of 5 to 20% is preferable from the viewpoint of providing a blade-preventing material having excellent flexibility and motility. Specifically, the fabric that wraps the blade plate, the front and back fabric to be sewn may be polyester fabric, cotton cloth, etc., but the edge face of the blade plate has excellent friction and cut resistance and high strength. It is preferably a textile fabric. For example, fibers having a single yarn strength of at least 9 g / d, preferably para-aramid fiber fabrics are most suitable. However, other materials may be used as long as they are firm. Further, the bag material is made of a cloth having a mesh structure, such as a knitted fabric, which is breathable and lightweight, and is suitable for summer and the like.

The blade-preventing garment of the present invention comprises the blade-preventing material described above, and at least the waistline is constituted. The blade-proof material constituting the blade-proof garment preferably has a size such that the front body or the back body can be composed of 6 to 20 blade-proof materials. That is, the motility increases as the size of the blade plate, that is, the blade material, decreases and the number of blades increases, but there is an optimum number in view of processing cost and kinetic performance. The number of blade plates is most preferably around the waist, that is, 10 to 14 for the front body and 8 to 11 for the back body, respectively.

In the blade-preventing garment of the present invention, the blade-preventing material 1
It is preferable to change the size of the sheet, which has different motility depending on the site. That is, it is preferable that the blade protection member is made of different sizes depending on the body part. For example, it is preferable to have a structure in which the blade-proofing material that constitutes a portion having a relatively large bending angle and a large bending angle includes one that is smaller than the size of the blade-preventing material that constitutes the other portion. That is, on the flank or abdomen where the movement is large, a small blade is preferable, whereas the back and chest may be slightly larger. However, it is preferable that the sizes of the adjacent blades are made uniform to some extent in consideration of the overall movement. As a blade material that constitutes such a part,
It is not necessary to use only a small blade material, and it is preferable to combine various sizes and numbers depending on the degree of bending operation and the size of the bending angle. Here, as the region having the relatively large bending motion and the large bending angle, the largest region is the abdomen, followed by the lumbar region and the flank.

There are no restrictions on the type of clothes, but the vest is particularly convenient because it is lightweight and removes fatal wounds.

For example, the garment will be described in detail. That is, when the blade-proof material constitutes at least the waistline of the garment, the blade-proof material is sewn on the cloth portion at its four sides. The blade-preventing plate of the blade-preventing material has a structure in which the blades are connected, and the blade-preventing plates overlap in at least one of the vertical and horizontal directions. In that case, it is preferable that the blade-preventing plates of the blade-preventing material overlap in both the vertical and horizontal directions from the viewpoint of the blade-preventing property. In this case, the blade-preventing plates of the blade-preventing material are overlapped and connected in both the vertical and horizontal directions. As a constitution, between the two fabrics, the upper end of the blade-preventing material A is the front cloth and the lower end is Sew on the back fabric and attach the upper edge of the next blade protection material B to the front fabric at a position higher than the lower edge of the blade protection material A, and attach the lower part of the connecting plate B to the back fabric so that they overlap vertically. By configuring at least the girth with this structure, each blade plate expands and contracts due to the looseness of the fabric,
Therefore, blade-proof clothes (including waistcoat) that can be bent and have excellent mobility can be obtained.

Here, a method of evaluating the blade-proof property will be described. The blade resistance is evaluated by comparing the maximum strength of the blade material when it is pushed with a commercial knife and an ice pick at a speed of 1 cm / min. As for the metal plate, a stainless steel plate with a thickness of 0.8 mm and an aluminum alloy with a thickness of 2 mm can obtain a strength of 200 kg or more.

The motility is calculated by the following formula by measuring the shrinkage ratio in each of the vertical and horizontal directions with a blade plate connected by a cloth.

Motility = [(AB) / A] × 100 (%) Length of blade plate when pulled by 1 kg load (cm) Length of blade plate when compressed by 1 kg load ( cm) The present invention will be described below with reference to the drawings.

EXAMPLES The present invention will now be described specifically with reference to examples, but the present invention is not limited to these examples.

Example 1 As a blade plate, a stainless steel S-4 steel plate was made with a laser to form holes having a diameter of 1.5 mm and an aperture ratio of 15% at regular intervals to form a blade plate, and as shown in FIG. It was made into a small piece and bent to have a curvature of 300R so as to fit the human body. The length x width of each blade is 65 x 140 for a and 65 x 15 for b
0, c and e are 95 × 160, d is 95 × 180, f and h
Is 95 × 170, g is 95 × 160, i and h are 75 × 1
80 and j were 75 × 140, and k was 75 × 180. c
And e hit the sides and have a curved shape.

A flat woven fabric of polyester 200 denier was folded on the blade plate and cut into 10 mm larger pieces than the blade plate pieces to wrap the blade plate k, and the edge and the material of the next inner bag were folded. Sewn within 10 mm from the position and the blade plate j is k
Then, the blade-preventing plate i was sewn so that the blade-preventing plate i was placed under the j, and the lateral blade-preventing plates were connected. At this time, the movement of the blade plate in one inner bag was 8 mm. This connected blade plate is sewn on the outer cloth 3 with the upper part of the inner bag containing the blade plate with two cloths of the outer material 3 and the lining material 3 ', and the lower part is sewn on the inner material 3'. Next, slide the blade plates f, g, and h that are connected in the horizontal direction so that the overlap margin is 10 mm from the first blade plate, and sew the upper part of the inner bag to the outer material and the lower part to the lining material. Blades c, d, e and ab connected in the direction
Was stacked in four steps to prepare a blade-proof waistcoat having a shape as shown in FIG. To this waistcoat with a blade plate attached to the front body, a polyester yarn woven fabric was attached to the back side, and a polyester yarn mesh knitted fabric was attached to the front side, and sewn to finish. The motility of this blade vest was measured by measuring the dimensions when a load of 1 kg was applied and when it was pulled and calculated by the above formula. The overall mobility in the lateral direction is 15%. Was enough to be able to. The longitudinal motility was 25%.
In addition, the thickness is 2.8 including the overlapping parts of the blade plate.
mm, and the plate central portion was 0.9 mm. When this was compared with the one in which the weight portion in the vertical direction was not displaced, it was made 25% thinner.

As a result of wearing a Y-shirt and a suit on the blade-proof waistcoat and walking, and a wearing test by simple work,
The abdomen was bent during work, especially when bent, and the blade vest was fitted to the body for excellent motility, and there was no hindrance during normal simple work, and wearability was good.

Next, the blade resistance is 250 kg with an ice pick,
With a cutting knife, a penetrating strength of 210 kg was obtained. This was a tough one that could not be penetrated by normal force. Also, in the test near the connection of the blade plate, the blade edge did not enter through the blind plate through the hole of the plate and the blade edge did not slip.

Example 2 Nylon 6 was mixed with 45% of glass and injection molding was performed to obtain a length of 10
A plate having a size of cm × width 15 cm and thickness 3 mm and a curvature of 300 mm was prepared, and a 2 mm hole was punched in the plate with a punching machine to prepare a blade-proof vest in the same manner as in Example 1. As a result, the blade resistance was 130 kg with an ice pick and 150 kg with a cutting blade knife, and a product with a weight of 100 kg which was difficult to penetrate even when cut was obtained. This plastic plate is lighter in weight than the stainless steel plate, and a product excellent in motility is obtained.

Example 3 In the same manner as in Example 1, the perforated stainless steel blade plate was 11 pieces as shown in FIG. 3 in the front body, and the back body was separately assembled with 9 plates to form a blade vest. It became heavier due to the front and rear blade plates attached, but the weight was small due to the fitting, and the movement was similar to that of Example 1 despite the small number of plates on the back body.

Example 4 In the same manner as in Example 3, a perforated stainless steel blade plate was assembled with 8 pieces on the front body and 6 pieces on the back body to form a bladed vest. As a result, the mobility is 18 in the front body in the longitudinal direction.
%, The back body becomes 11%, and each side is 1
It fell to 0.7% and became slightly difficult to move.

Similarly, when 25 pieces of perforated stainless steel blade plates were combined together in the front and rear bodies, the small movement was improved, and the motility was 33% in the vertical direction and 19% in the horizontal direction. , The weight was increased due to the overlap margin, and it took time to sew.

Example 5 A blade-proof vest was prepared in the same manner as in Example 1 except that a plain woven fabric of 200 denier Kevlar yarn, which was a para-aramid fiber, was used for the inner bag that wrapped the blade-proof plate. It was hard to tear even when pierced, and the gap between the blade plates did not widen, so the blade did not enter through the gap.
