Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a comfortable blade-proof garment excellent in motility, breathability and wearability as well as blade-proofness.

[0002]

2. Description of the Related Art As a conventional protective clothing, the whole body is 1
A single plate, a combination of multiple metal plates and plastic plates were used, but they are hard and inferior in mobility, and they do not have breathability and have a stuffy feeling in summer,
Stickiness due to sweat was severe and wearability and comfort were extremely poor, and wearers, especially police officers, did not like to wear them all the time. For example, Japanese Patent Application Laid-Open No. 48-63598 proposes a protective suit in which a vine winding strip structure in which a large number of vine winding strips are alternately intertwined is used as a protective wall and covered with a cotton-like substance. However, there is no technique that considers motility and wearing comfort while maintaining protection, particularly blade protection.

[0003]

That is, such a conventional protective material focuses on protecting the body from bullets, bursts and blades by the elastic restoring force of the protective wall, and is a cotton-like substance. It is not breathable because it is covered with, and it is not something that pursues wear comfort that is difficult to get damp, and the coiled one such as the vine winding strip structure is bulky and thick, and the blade, especially ice It has the property of opening its mouth when entering a pick or the like, and therefore, the blade-proof property is significantly reduced.

The present invention has been made in view of the above problems of the prior art.
First, it is an object of the present invention to provide a blade-proof garment which is excellent in motility and has excellent blade-proofness and comfortable wearability.

[0005]

The present invention employs the following means to achieve the above object. That is, in the blade-proof clothing of the present invention, at least the front body is composed of a stainless wire wire mesh having a mesh structure connected in a corrugated shape, and the wire diameter of the stainless wire is 0.1.
~ 1 mm, the corrugated pitch (P) and the wire diameter (D)
Ratio (P / D) of 3 to 6 and the wire mesh thickness of 0.5 to 5 m
m.

BEST MODE FOR CARRYING OUT THE INVENTION Conventional protective materials and protective vests made of such materials are hard and lacking in mobility, and in the summer they are extremely stuffy, and when they sweat, they are extremely sticky and not very uncomfortable. It was something I dislike doing.

[0007] Among such protective materials, the present invention has a blade that protects the body, is flexible and has excellent motility, and is comfortable to wear with little sweating or stickiness even in the summer or during exercise. As a result of diligent studies to provide a blade-proof garment that exhibits a feeling, it was discovered that a metal wire net rolled into a flat shape has unexpectedly excellent blade-proof properties.
That is, the present invention is a wire mesh sheet that prevents misalignment by rolling a wire mesh made by intertwining spiral metal wires for each node and flattening it, and exhibits a bending function that cannot be obtained by conventional protective materials. However, it is light, flexible, and has mobility.

The metal wire referred to in the present invention may be iron or copper, but is preferably made of a metal such as stainless steel plate, aluminum alloy, pure titanium or titanium alloy, which is light and has excellent toughness. Stainless steel that is thin and strong and is inexpensive is more preferably used. The metal wire having a wire diameter of 0.1 to 1 mm, preferably 0.3 to 0.8 mm is used from the viewpoint of mobility, blade resistance, and comfortable wearability.

In order to form a metal mesh connected in a corrugated shape from such metal wires, a plurality of spirals can be obtained by winding the metal wires around a rod-shaped object to form a spiral shape and then engaging them by rotating them one by one. The metal wire may be in the form of a wire mesh in which the metal wires are intertwined and engaged with each other at each node of the spiral. This is pressed or rolled by a metal roller, a press or the like to crush the entire wire mesh into a sheet having a thickness of 0.5 to 5 mm, preferably 1 to 3 mm. By this flattening and flattening of the metal wire mesh, a metal wire metal wire mesh is formed in which the sealing is achieved but the bendability of the engaging portion between the metal wires is maintained.

The corrugated metal wire has an outer total length (H) including the lengths of peaks and valleys of the corrugated metal wire, that is, the diameter of the metal wire.
And the total thickness (T) on the outer side in the thickness direction of the wire mesh (H /
When represented by T), it is preferably used in the range of 1.2 to 2.5, and more preferably 1.3 to 2 from the viewpoint of blade resistance and comfortable wearing feeling.

The above-mentioned wave-shaped pitch (P) is measured at a pitch from peak to peak, and the length is not particularly limited, but is preferably 0.7 to 4 mm, more preferably 1 to 4. A range of 3 mm is adopted from the viewpoint of sealing property and blade prevention property. In the wire mesh of the present invention, the ratio (P / D) of the pitch (P) and the wire diameter (D) is 3 to.
In the case of 6, preferably 4 to 5, it is possible to provide a wire net having excellent effects of the present invention.

Further, the wire mesh of the present invention has a characteristic porosity such that the aperture ratio is preferably 30% or more, more preferably 35 to 45%. Such a porosity has an effect of well balancing the air permeability and the blade prevention property.

In such a wire mesh, depending on the diameter of the metal wire, if pressed or rolled too much and crushed to a thickness of less than 1 mm, the movement and bendability of the metal wire deteriorate and the flexibility is impaired. However, if it exceeds 3 mm and is not crushed too much, the blade-proof property is impaired. The metal wire wire mesh of the present invention,
It has a feature that it is slightly hard in the lateral direction, that is, in the orientation and arrangement direction of the corrugated metal wires, but is sufficiently flexible in the vertical direction, that is, in the metal wire connection and engagement directions. Therefore, in order to utilize such a wire mesh as clothes by making the best use of its characteristics, it is necessary to pay attention to the design such as arrangement and arrangement in which the bending direction of the wire mesh is sufficiently considered.

For example, the degree of bending of each part of the body is greatly different, and if this is made up of a single wire net, the motility is greatly impaired. For example, in the front body of clothes, there is a considerable difference in movement between the chest and abdomen, and greater flexibility is required near the abdomen compared to the chest, so by dividing the chest and abdomen in two, The flexibility can be covered and absorbed by the divided portions.
That is, it is preferable that the parts and portions that are particularly required to have flexibility and flexibility are arranged by dividing, that is, by providing a cut. In such a cut portion, it is preferable to use two wire nets in a stacked manner in order to prevent generation of a gap. The length of the overlapping portion is preferably 5 to 15 mm,
More preferably, it is about 8 to 12 mm.

The blade-proof garment of the present invention achieves sufficient blade-proofness even if it is made up of only wire mesh, but when further protective properties are desired, for example, to protect the heart, a plastic plate or a metal plate is used. A composite material with a protective plate such as is preferably used. That is, even with the metal wire mesh of the present invention described above, the blade-proof property for something like an ice pick whose tip is extremely sharp among blades is slightly inferior to that of the protective plate. It is preferred to reinforce the plate. As such a portion or portion, there is a heart portion in particular, and a metal laminated wire mesh is used in the vicinity thereof. As such a protective plate, one having an area suitable for the size of the site is used. Specifically, it is preferably about 100 to 20.
A protective plate having an area of 0 cm ² , more preferably about 150 cm ² is laminated and reinforced. As the protective plate, for the metal plate, the above-mentioned raw material of the metal wire can be used, but like the metal wire, stainless steel is preferable because it has particularly excellent protection properties. If the area is wide, the area becomes harder and the weight increases, and if the area is small, the area is inferior in the defense ability against a side impact. Therefore, it is necessary for the person to be protected to appropriately design the area. For the plastic plate, a plastic that is resistant to impacts and blades, such as polycarbonate, polyamide imide, and a laminated plate of nylon 6 / glass or the like can be used. Such a plastic plate has the advantage of being light and excellent in movability, but is inferior in impact resistance and blade resistance to a metal plate.

The front body constituting the garment of the present invention is as described above. In this case, the back body, that is, the back, may be made of only mesh cloth, but if necessary, it may be laminated with the protective plate in the same manner as the front body. Materials may be used. However, in that case, the increase in weight reduces mobility and breathability. In the blade protective clothing of the present invention, the protective plate laminated material is preferably used only in the front body, and also only in the region of the heart region. With such a configuration, it is lightweight, has high mobility, and is excellent in breathability and comfort. The effect is that there is no resistance even if it is worn all the time.

The lamination of the protective plate and the metal wire wire mesh is
The protective plate may be provided with a hole through which a needle penetrates, and a thin wire or sewing thread may be engaged and connected through this hole. Also, a bolt-nut connection, and in the case of a metal plate, solder or solder may be used. A method of joining with a metal rod such as welding, or a method of joining with an adhesive in the case of a plastic plate may be used, but since the protective plate is a small piece and flexibility etc., it is easy and easy to join with a sewing thread. preferable.

The blade-proof clothing of the present invention has been described above. In order to exhibit the characteristics of these blade-proof clothing which is flexible, has a large breathability, and is excellent in comfort, a dress material,
It is desirable to have a laminated structure with a cloth such as a cover material and a lining material. As such a cloth, one having high air permeability is preferably used. For example, it is preferable to use a nylon or polyester mesh fabric for the outer material and a polyester fabric, a Kevlar fabric, or another fabric having high abrasion resistance to metal for the cover material. Also, the lining has a vertical length of 5
Sweat is used on the surface by designing it with a double woven fabric with 0 denier and 75 or 150 denier polyester yarn, and with a double density structure in which the surface density of the surface is higher than that of the back. It is possible to provide a comfortable blade-proof garment that can be diffused and is not sticky.

In the present invention, the blade-proof property is evaluated by comparing the maximum strength of the blade-cutting knife and the ice pick when it is pushed at a speed of 1 cm / min to measure the maximum strength.

According to the metal wire metal net of the present invention, for example, a stainless wire metal mesh has a wire diameter of 0.6 mm, a cutting knife of 120 kg, an ice pick of 60 kg, and a wire diameter of 1.0 m.
With a m, a strength of 180 kg for the Deba knife and 90 kg for the ice pick was obtained. For metal plates, the stainless steel plate thickness is 0.
With a thickness of 8 mm, an aluminum alloy having a thickness of 2 mm was able to obtain a strength of 200 kg or more, and a heart portion in which a metal plate was laminated on a stainless wire mesh obtained a strength of 300 kg or more.

The present invention will be described below with reference to the drawings.

FIG. 1 shows one spiral stainless wire of the blade vest of the present invention, where a is a spiral state and b is an enlarged sectional view surface. As can be seen from the figure, the thickness is reduced by pressing. FIG. 2 is a plan view in which spiral stainless wires are entangled at each node and assembled into a metal net, and the gap is small and it is difficult for a knife to enter and the mesh is difficult to open. FIG. 3 is a comparative diagram. a is a vine winding strip that is not pressed, and b is a cross-sectional view showing an example in which the thickness is large and the mobility is lowered due to being bulky.

There was 0 cc / sec · cm ^2, and the air permeability was great.

Wearing a protective vest on a cotton shirt, and wearing a Y-shirt on it, the wearability was evaluated. As a result, it was found that there was little stuffiness, and that sweat diffused to the surface of the lining even after sweating after exercise. There was no stickiness, and there was no feeling of coldness even when the body became cold after sweating, and the wearability was good. Moreover, it was flexible and had good motility in normal work. Blade resistance is 6 with an ice pick
A strong product of 0 kg and a cutting knife of 120 kg was obtained, and blades were prevented from the front and back, and a highly safe product was obtained.

Example 2 A protective plate processed in the same manner as in Example 1 was cut as shown in FIG. 5, and the respective dimensions were 45 cm in width × 11 cm in length and 45 c in width.
Two boards measuring m × 20 cm in length were covered with a polyester denier fabric of 150 denier, and the boards were sewn with a 10 mm overlap margin. Then, a mesh knitted fabric of 150 denier polyester was sewn as a front side fabric, and a double weft fabric of 50 denier in the length direction and 75 denier in the width direction was used as a back side fabric. A mesh fabric was attached to the back of this, and a blazer outer material was sewn on these wire mesh waistcoats to prepare a blade-proof blazer.

As a result of wearing the blade blazer on the Y-shirt and evaluating the wearability, there was little stuffiness, sweat did not spread to the surface of the lining even after sweating after exercise, and there was no stickiness. The wearability was good without feeling cold when cold. In addition, the protection plate is flexible in the lateral direction and flexible, and the vertical movement has little bending in the chest, but there is bending in the abdomen, which does not hinder the mobility due to flexion and extension, and the mobility is good. It was This blazer showed a blade-proof property of 120 kg for a cutting knife and 60 kg for an ice pick.

Example 3 A protective blade made of the wire mesh of Example 1 was further laminated on the left chest of the heart with an area of 150 cm ² of a 0.8 mm stainless steel plate from above to prepare a bladed vest, and a wearing test was conducted. did. There is a danger that the protective plate made of stainless wire mesh penetrates for a few millimeters if it is strongly struck with an ice pick, but the heart of this waistcoat is 320 kg against the blade knife and 270 kg against the ice pick. It was In addition, the area of the metal plate was small and did not get stuffy, and the chest had a small movement, so there was no particular inconvenience in motility.

Example 4 A spiral stainless steel wire having a wire diameter of 1.0 mm and 3 wires / cm was combined to form a wire net having a density of 4 wires / cm, which was pressed to form a protective plate having a thickness of 2.5 mm. . In the same manner as in Example 1, a blade vest was created and a wearing test was conducted. It was slightly heavier than Example 1, but had good motility, no stuffiness and stickiness, and a good wearing feeling. The blade-proof performance is higher than that of Example 1, 180 kg for the cutting knife and 90 kg for the ice pick.
It showed a blade resistance of kg.

Comparative Example 1 As the protective plate, the wire net made of the spiral stainless wire of Example 1 was used as it was without rolling. The thickness is 3.
The size was 2 mm, and a more flexible product was obtained with a gap formed, but the ice pick showed a blade-preventing property of 40 kg and the blade knife 100 kg.

It became stronger and slightly lower than the rolled one.

Further, the protective plate had a higher density than that when rolled to 1 mm and showed a blade-proof property of 70 kg with an ice pick and 130 kg with a cutting knife. Met.

COMPARATIVE EXAMPLE 2 A protective plate made of the wire mesh of Example 1 was further used, and a 0.8 mm stainless steel plate having an area of 80 and 250 cm ² was formed on the left chest of the heart.
Was laminated from above to prepare a blade-proof waistcoat, and a wearing test was conducted. There was a risk of penetrating for a few millimeters when struck with a strong ice pick, and when the area of the stainless steel plate was 80 cm ² , there was a risk of piercing for a few millimeters when it was struck from the side with an ice pick. When the area is 250 cm ² , reinforcement of the heart portion is sufficient, but the weight becomes large, and the flexibility of the wire mesh is impaired, which is not good. The heart of this vest showed a blade-proof property of 320 kg against a cutting knife and 270 kg against an ice pick.
