Description

The present invention is primarily flying to debris and bullets, more ice pick relates ballistic protection clothing with ballistic protection member to be used to protect the body from tool such knife. Specifically, workability and activities that use anti-ballistic protection members that can safely mitigate impacts on the human body, such as when the above-mentioned flying objects land, are less likely to be caught by surrounding projections, and have good follow-up to the body. It is related to the bulletproof defense clothing excellent in property.

  Police officers, guardmen, soldiers, etc. are tolerated as necessary to protect themselves against attacks by firearms from criminals, terrorists, enemy soldiers and suspicious individuals, and attacks by fragments and blades flying due to explosions of explosives. Engage in duties while wearing bulletproof clothing using bulletproof members. As a bulletproof defense member, there is a demand for a safer member that not only stops the flight of various bullets, fragments, etc., but can also reduce the impact on the human body when a projectile collides.

  Conventionally, as a bulletproof defense member having a high performance for stopping flying objects, high strength fibers such as para-aramid fibers, polyethylene fibers, polyparaphenylene benzobisoxazole fibers, etc., and these fabrics are coated with resin or resin. There are known impregnated materials and shield materials made using these fibers. The shield material here refers to an anti-ballistic material in which a laminate of a sheet in which high-strength fibers are orthogonally arranged at 0 degrees and 90 degrees and laminated and impregnated with a resin and a synthetic resin film are laminated. Say.

Recently, for example, Patent Document 1 discloses a flexible ballistic member having a surface density of ² to 10 kg / m ² and including a plurality of fabric layers. This is because at least two of the layers of fabric are coarsely woven, the coarsely woven fabric layer comprises a fabric woven with a fabric tightness factor of 0.3 to 0.6, and at least 200 dtex Made with continuous filament yarns having a linear density, a tenacity of at least 0.98 N per dtex, and a tensile modulus of at least 1.47 N per dtex. Further, adjacent coarse fabric layers are joined together by means for securing the layers so as to limit the relative movement of the coarse fabric layers. The fabric tightness factor refers to the ratio of the actual cover factor to the maximum possible cover factor of the woven structure. The cover factor represents the ratio of the yarn covered with the total surface area of the fabric.

  However, although this bulletproof defense member is able to stop the bullet when it receives a bullet of a handgun, it cannot sufficiently mitigate the impact on the body at the time of landing, and the internal organs are damaged by the impact at the time of landing. There was a risk of fracture or fracture.

  On the other hand, trauma plates have been used to reduce the impact on the body when landing. A trauma plate is used by being inserted between a body and a bulletproof defense member, and disperses impact energy when a bullet or the like lands, thereby reducing local damage to the body. The trauma plate is made of a material having high rigidity with respect to the bulletproof defense member, and is generally made of a foamed resin sheet, a resin plate, or a metal plate. In particular, the metal plate is preferably used because it has good impact relaxation performance and at the same time can provide sufficient blade resistance.

  However, when the trauma plate is made of a metal plate or a resin plate, there is a problem that the trauma plate becomes a fragment due to an impact at the time of landing and jumps out to the body side or an increase in weight.

  In recent years, bulletproof panels and bulletproof vests have been constructed with a layer of bulletproof material and a semi-rigid frame structure attached to the layer of bulletproof material in order to alleviate the impact on the body and reduce weight. It is disclosed that an opening is provided over the entire frame structure (Patent Document 2).

However, such a configuration reduces the impact compared to the case without a frame structure, but the material does not reduce the impact because the material is shaved. The blade resistance performance obtained with the trauma plate cannot be obtained.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings with specific examples. As shown in FIG. 1, the bulletproof defense member according to the present invention has a main bulletproof layer 1, a trauma plate layer 2, and a fracture-proof piece layer 3 laminated in this order from the protective surface 4 side. In the present invention, the protective surface 4 is the surface on the side where the bullet hits, and the back surface 5 is the back side of the protective surface 4, that is, the surface on the wearer's body side.

The main bulletproof layer 1 arranged on the side of the protective surface 4 is a layer arranged mainly for the purpose of stopping bullets, and passes the bulletproof defense test NIJ Standard0101.04 Type IIIA at an area density of 8 kg / m ² or less. Any bulletproof material can be applied. Among these, it is preferable that the fiber is made of a high-strength fiber woven fabric, a shielding material, a resin-impregnated high-strength fiber woven fabric, a resin-coated high-strength fiber woven fabric, or the like.

  The high-strength fiber here means a fiber having a tensile strength of generally 17 cN / dtex or more, more preferably 19 to 40 cN / dtex. Specifically, aromatic polyamide (para-aramid), aromatic polyether amide, wholly aromatic polyester, ultrahigh molecular weight polyethylene, polyvinyl alcohol, polyparaphenylene benzobisoxazole, polybenzimidazole, polyimide, polyether ether ketone , Polyetherimide, polyphenylene sulfide, novoloid, polypyridobisimidazole, polyarylate, polyketone, polytetrafluoroethylene, polyoxymethylene, polyacrylonitrile, polyamideimide, polyetherketone, etc. In view of productivity, price, etc., para-aramid fibers, ultrahigh molecular weight polyethylene, polyparaphenylene benzobisoxazole, and polypyridobisimidazole can be particularly preferably used.

What is necessary is just to design suitably the kind of material which comprises the main bullet-resistant layer 1, and the number of lamination | stacking according to the design of the target bullet, the trauma plate layer 2 mentioned later, etc.

The trauma plate layer 2 laminated on the back side of the main ballistic resistant layer 1 is disposed for the purpose of dispersing local impact at the time of landing and reducing damage to the human body due to the impact. . The trauma plate is not particularly limited as long as it is generally classified as a trauma plate. For example, a foamed resin sheet, a resin plate, a metal plate, or the like is used. In particular, the impact relaxation performance of the metal plate is good, and blade resistance can be imparted, which is preferable. When a trauma plate imparts not only impact mitigation but also blade resistance performance, a metal plate or a resin plate that passes the blade resistance test NIJ Standard 0115.000 Spike & Edged Blade class level 1 at an area density of 7 kg / m ² or less is preferable, among which duralumin Plates, titanium plates, titanium alloy plates, stainless steel plates, and polycarbonate plates are particularly excellent in terms of blade resistance, cost, productivity, and workability.

  As shown in FIG. 2, the fracture-resistant piece layer 3 disposed on the back side of the trauma plate layer 2, that is, the position closest to the body, greatly damages the main bullet-resistant layer 1 and the trauma plate layer 2 due to impact upon landing. Even if a broken piece 9 or a sharp broken end protrudes to the body side, it is arranged for the purpose of preventing the body from being injured. In the case where the break-proof piece layer 3 is not provided, as shown in FIG. 3, a very dangerous configuration in which fragments and the like may jump out to the body side is obtained.

Any material that can pass the ballistic resistance test NIJ Standard 0101.04 Type IIIA at an area density of 8 kg / m ² or less can be applied to the material of the fracture-proof piece layer 3 as in the case of the main ballistic layer 1. Among these, it is preferable that the fiber is made of a high-strength fiber woven fabric, a shielding material, a resin-impregnated high-strength fiber woven fabric, a resin-coated high-strength fiber woven fabric, or the like. Moreover, what is necessary is just to design suitably the kind of bulletproof material, the number of lamination | stacking, etc. according to the structure of the target bullet, the main bulletproof layer 1, and the trauma plate layer 2. FIG.

  By laminating the main bullet-resistant layer 1 and the trauma plate layer 2 in this way, the impact at the time of landing can be greatly reduced. Further, by laminating the anti-breaking piece layer 3, the main Safety can be maintained even when the layer 1 or the trauma plate layer is broken and fragments are produced.

  In the present invention, the impact at the time of landing can be further alleviated by laminating a resin foam sheet on the body side of the bulletproof defense member, that is, on the side opposite to the trauma plate layer 2 of the fracture prevention layer 3. A possible configuration. Moreover, a wear feeling also improves from the softness | flexibility.

  The above bulletproof defense member is used for bulletproof defense clothing as shown in FIGS. FIG. 4 is a diagram showing a configuration example of the surface (protective surface side) of the back body 10 of the bulletproof defense clothing of the present invention, and FIG. 5 shows the surface (protection) of the front body 50 of the bulletproof defense clothing of the present invention. It is a figure which shows the structural example of the (surface side). FIG. 6 is a diagram showing the back side of the front body of the bulletproof defense clothing of the present invention, and FIG. 7 is a development view of the front body of the bulletproof defense clothing of the present invention.

  In the present embodiment, the bulletproof defense clothing is provided with a back body 10, a front body 50, and a shoulder pad for protecting the shoulder from the back body 10 so as to be fixed to the front body 50 beyond the shoulder. It consists of a buckle 29 and the like.

  By appropriately selecting a protective plate to be provided on the shoulder pad 12, it is possible to impart blade resistance, cutting ability, impact resistance, and the like. In addition, since the front body 50 and the back body 10 are fixed by the buckle 13, when removing the protective clothing, the buckle 13 is fixed on both the left and right sides so as to be worn or worn, or the buckle 13 is removed and sandwiched. It is possible to detach and attach to the wearer, and it is possible to select a method that is easy for the wearer to wear. Moreover, if the size adjustment mechanism 11 is provided in the buckle 29 with a shoulder pad, it becomes a structure applicable also to people of more body types.

  Further, in the bulletproof defense clothing according to the present embodiment, the belt 14 with hook-and-loop fastener for fixing the front body 50 and the back body 10 on the flank is provided on the back body 10, and the belt 14 with hook-and-loop fastener is sized. An adjustment mechanism 16 is provided. Although this size adjustment mechanism 16 is configured to be applicable to a large number of people, the wearer can further adjust the size by fixing the hook-and-loop fastener at a preferred position. Further, if a stretchable material such as rubber is used for the belt 14 with the hook-and-loop fastener, the size can be easily adjusted.

  In the present embodiment, the size adjusting mechanism 16 is covered with a fabric such as the pocket 17. With such a configuration, it is possible to prevent the wearer from being caught by surrounding protrusions or the like during work. Note that the pocket 17 is a device in which the size adjusting mechanism 16 is covered with a cloth as shown in FIG. 4 and an opening is provided so that the size can be adjusted. By attaching a button or the like, it can be configured to be more difficult to catch.

  In the bulletproof defense clothing having such a configuration, the bulletproof defense member described above is used for at least the front body 50. At this time, as shown in FIG. 7, if the resin foam sheet (resin foam sheet body 24) is arranged further on the body side of the bulletproof defense member (ballistic defense member body 27), the impact at the time of landing is further reduced. In addition, it is preferable because flexibility at the time of wearing can be increased. In this embodiment, as shown in FIGS. 6 and 7, the resin foam sheet and the bulletproof protection member are placed in the pocket of the cloth sewn in the shape of the bulletproof defense clothing, The resin foam sheet body 24 and the bulletproof defense member body 27 are formed by being inserted from the bulletproof defense member insertion opening 28 respectively. Therefore, the resin foam sheet and the bulletproof protection member are not exposed directly.

  As shown in FIG. 7, it is preferable that the bulletproof defense member (ballistic defense member body 27) and the resin foam sheet (resin foam sheet body 24) are fixed to each other on the central vertical line when worn. When the fixed part of the bulletproof defense member (ballistic defense member body 27) and the resin foam sheet (resin foam sheet body 24) is substantially on the central vertical line when worn, the thick bulletproof defense member Even in the case of using, it becomes a bulletproof defense garment having good wearability. That is, by making the bulletproof defense member and the resin foam sheet free at the left and right side portions of the front body, the followability of the bulletproof defense clothing in the body circumferential direction is improved. More specifically, a bulletproof defense member (bulletproof defense member body 27) and a resin foam sheet (resin foam sheet body 24) are sewn, for example, at both shoulder openings 30 and with a hook-and-loop fastener 26 at the center of the lower abdomen. It is preferable to fix. Here, the center part of the lower abdomen refers to an area in the range of 10 cm on each side and 15 cm on the upper side from the middle point of the lowermost part of the front body of the protective clothing. If it deviates from this region, the protective clothing and the resin foam sheet are likely to be displaced, resulting in a configuration with poor wearability. The other parts are free without being fixed to the resin foam sheet (resin foam sheet body 24) and the bulletproof defense member (ballistic defense member body 27), so that it is easy to follow the movement of the body. It becomes bulletproof defense clothing with good wearability.

Hereinafter, the present invention will be described in detail by way of examples, but the bulletproof resistance was evaluated by a V0 test defined by NIJ-Standard0101.04. A 44 Magnum bullet (15.6 g, bullet velocity 436 m / s, manufactured by REMINGTON) was used as the bullet, and the presence or absence of the bullet penetration and the depth of the clay dent on the back of the sample were confirmed. Oil clay (Roma Plastina # 1) was laid on the back side of the bulletproof protection member as a sample, and the sample was fixed with a belt. The test was carried out at a room temperature of 25 ° C. and a humidity of 35%.
The blade resistance was evaluated by a blade resistance test defined by NIJ-Standard0115.00. The blade was tested at the energy level defined in level 1 using Spike, BladeP1, and BladeS1 defined in the Spike & Edged Blade class, and evaluated by measuring the penetration length of the blade to the back side of the sample.
