DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blade protection device for protecting a body from stab damage caused by an ice pick or a blade.

[0002]

2. Description of the Related Art There are many examples of using a synthetic resin panel for absorbing kinetic energy of a blade in a blade-proof tool. For example, in JP-A-7-243796, as specific examples of the synthetic resin, polyurethane, P-aramid, ionomer,
Polycarbonates, fluorinated hydrocarbons, polyetherimides, especially cross-linked ethylene-ethylene acrylic acid copolymers (ionomers) are described as being suitable. In the drawings of the examples, it is described that the honeycomb layer exhibits a blade-proof property in a multilayer structure. Japanese Patent Application Laid-Open No. 10-89898 discloses an example in which a plastic plate is inserted into at least the heart of the front body of a vest. Polycarbonate, nylon /
A glass-filled plastic plate is illustrated.

[0003] An example of co-use of a synthetic resin plate and aramid fiber in protective clothing is disclosed in JP-A-2-39474. In this case, a nylon-based resin is exemplified as the synthetic resin plate. Further, Japanese Patent Application Laid-Open No. 10-281697 describes that a fiber impregnated with a synthetic resin adhesive, for example, a linear saturated polyester resin, strongly adheres a bullet (the right column on page 2 at the bottom right). The resin impregnated with high-strength fiber is said to be able to completely protect against piercing and hitting by an ice pick or a blade. (Left column on page 3 of the gazette).

[0004]

As described above, the use of synthetic resins to protect themselves from piercing blades and the like has been often proposed and put to practical use. Conventional synthetic resin in these known examples is a single plate, laminated with fibers, multiple layers with honeycomb, or assembled with a large number of small pieces in an armor shape, and the cutting tool is held to pierce The kinetic energy present can cause the blade or the like to hit, break, or pierce the synthetic resin plate, fiber, honeycomb, or small synthetic resin piece, causing physical damage. Simply hitting a blade or the like with a synthetic resin plate or a small piece of synthetic resin cannot prevent an excited criminal from attacking again.

Japanese Patent Application Laid-Open No. 10-281697 discloses that a fiber impregnated with a synthetic resin adhesive, for example, a linear saturated polyester resin, strongly adheres to a bullet. The bullet is adhered to the bulletproof layer formed by the saturating polyester resin. A large number of fibers and a synthetic resin adhesive are laminated on this bulletproof layer. It is described that the linear saturated polyester resin has excellent heat resistance and will not be melted by heat, and it will tear in the direction of the woven fiber to cope with piercing and hitting with an ice pick or blade. The fact that the crack does not become large contributes. However, even though this is effective at flying at a high speed such as a bullet and having high kinetic energy, it is difficult to pierce with an ice pick or a blade, etc. There is a drawback in that even if the stab can be performed, the criminals can quickly remove the stab and can go to the stab again after the stab fails.
An object of the present invention is to provide not only a function of simply receiving and avoiding a blade or the like as in the related art, but also a blade preventive device that is not repeatedly attacked by a criminal.

[0006]

As a result of examining the above-mentioned problems, a room temperature solid resin in which the kinetic energy of a piercing blade is converted into heat energy and the stickiness increases is arranged on the blade receiving surface. In addition, the kinetic energy of the blade that pierces the body part of the garment to be protected is converted into thermal energy, and a normal temperature solid resin that increases the adhesiveness is provided.

In the present invention, the kinetic energy is converted into thermal energy. When the piercing blade enters the thickness direction of the room temperature solid resin, the portion where the blade and the room temperature solid resin come into contact with each other frictionally moves. The conversion of energy into heat energy. This thermal energy melts the room temperature solid resin or increases the adhesiveness of the room temperature solid resin, preventing the blade from penetrating deeply.Also, due to the adhesiveness (contact property) or adhesiveness of the resin, a criminal can pull out the blade. You will not be able to do it.

A room temperature solid resin exhibiting such properties is a resin excellent in low-temperature contact property or adhesiveness at a melting point of 200 ° C. or lower. Resins such as rosin esters, hydrogenated rosin esters, dibasic acid-modified rosin esters, polymerized rosin esters, terpene phenols, etc., alone or in other appropriately selected synthetic resins having good compatibility are used as such room temperature solid resins. And molded, but not limited thereto. In addition, rosin, polymerized rosin, hydrogenated rosin, diacid-modified rosin represented by maleic acid-modified rosin,
Natural materials such as terpene phenolic resin, styrene-maleic acid copolymer resin, maleic acid resin and acrylic resin also have a softening point of 100 ° C or less and have solid or tackiness at room temperature, and are more sticky when melted. This is suitable for the present invention because it becomes unnecessary.

The above-mentioned ordinary temperature solid resin is attached or placed in the form of a plate or a lump to the blade receiving surface of the blade-proof tool of the present invention or the body part to be protected of clothes. The blade protection device of the present invention referred to herein includes all parts of the body to be protected, that is, all the protection devices used from the head to the toes. In other words, the best shape, size and thickness for the well-known parts to protect the body such as helmets, vests, clothes, pants, shoes, etc. The resin is arranged or arranged. The kinetic energy of 25 to 35 J at the time of piercing the thickness by the blade becomes thermal energy, and is a thickness sufficient to be absorbed due to melting or increase in tackiness of the resin, and varies depending on the properties of the resin used. The lower the melting point and the softening point, the greater the thickness. The higher the melting point and the softening point, the smaller the thickness.

FIG. 1 is a development view of the blade-proof tool of the present invention in the form of a vest, FIG. 2 is a side view when worn, FIG. 3 is a front view of the blade-proof tool of the present invention formed on a shield, and FIG. It is a part enlarged sectional view. As is apparent from these figures, the blade-proofing device of the present invention can take any form as a device for protecting the body. 1 and 2 show a vest structure that also serves as a bulletproof vest. A shield structure shown in FIG. 3 or the like other than the one worn on the body can be used.

In the vest 1 shown in FIG. 1 and FIG.
A resin plate 4 is provided in which the kinetic energy of the blade piercing the body part of the rear body 3 to be protected is converted into heat energy to increase the adhesiveness. As a mode of arrangement, the vest is inserted into a storage bag provided at a key point of the waistcoat, or a mounting hole is provided in the resin plate 4 and fixed to the key point with a hook or a thread. In the case of being housed in a housing bag, it may be tacky at normal temperature.

As shown in FIG. 3, on the front surface of the shield 5, a resin plate 4 (dibasic acid-modified rosin, melting point of 200 ° C. or less, whose adhesiveness is increased by converting kinetic energy of a piercing blade 6 into heat energy. ) Provided on the blade receiving surface with one or a plurality of the blades with their edges overlapping each other is a particularly excellent blade-proof tool. That is, as shown in FIG. 4, when there is an attack by the knife 6 such as a kitchen knife or a pickle, the kinetic energy of piercing of the knife 6 is converted into heat energy, and the adhesive state increases due to the increase in tackiness or the contact property. Therefore, even if you apply force, you can not only pierce it anymore, you can not pull it out. This makes it easier to catch criminals immediately.

[0013]

The blade-proofing device of the present invention is not limited to the function of simply receiving and avoiding a blade or the like as in the prior art, but it is difficult to pull out once the blade has been pierced. You can avoid receiving them, and you can arrest criminals immediately after the raid. Therefore, it is possible to prevent crime and increase the arrest rate.
