Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a device for protecting a human body from damage by a blade, and is worn by a person working in a field exposed to an unexpected attack such as a police officer or a guard man. Alternatively, it is used for a human body protective clothing worn by a worker who always uses a blade.

<Prior art> Adding a human body protection function to clothing worn by humans is
It has been practiced for a long time without waiting for the armor of the era when fighting with blades and spears as weapons.

Since the advent of the gun, various attempts have been made to deal with it with bulletproof clothing, especially after a pistol that can be carried in normal clothing has appeared in society, in normal clothing to protect against the danger of a pistol, a bulletproof vest. Has been developed.

Recently, for example, there is a proposal of bulletproof blade underwear disclosed in JP-A-58-19700. This invention is intended to provide underwear having a bulletproof and bladeproof function by combining a protective material having a bladeproof effect that stops blade blades to ice picks with a known bulletproof fiber sheet. The body has a structure in which the blades are unfolded in one layer, and the round blades are connected to each other by the connectors of two types of shapes, and a part of the connector and the blade has a two-layer structure. The blade protection function only works as a single layer structure of the blade.

<Problems to be solved by the invention> In the conventional ones, there are some that are sufficiently satisfied with the bulletproof function, but in those that try to achieve the blade-proof function, the wearability is extremely deteriorated or the wearability is reduced. In order to prevent lowering, it is necessary to construct the object with attention to the fit to the human body by dividing it into small pieces, so the gap between each small piece was powerless against the thin blade during blade protection. In addition, if the function of preventing blades against thin blades is fulfilled, it is necessary to impart uniform strength without gaps to the entire surface of the blade material,
After all, it became a connected body of small pieces and had to sacrifice the fit to the human body.

The present invention skillfully solves the trade-off between the requirement of the blade-preventing function and the wearability, that is, the requirement of fitting to the human body, which conventional products have.

That is, the present invention does not provide a protective garment that withstands the piercing of thin blades such as ice picks, can be worn in the same condition as the normal garment throughout the four seasons, and has both breathability and fit to the human body. It is what

<Means for Solving Problems> The present invention forms the blade material from a small piece group in order to impart flexibility, so that no gap is formed at the abutting edge of each small piece group, and
It is intended that there is no weak point for a thin blade anywhere, and two plate-like small pieces for blade protection having the same shape and a predetermined thickness are appropriately shifted and integrated, and two plate-like small pieces are provided in the central portion. A thickness is formed, and a protruding portion having a thickness corresponding to one plate-like small piece protruding by an amount shifted to the upper and lower surfaces of the peripheral edge is formed as a blade-proof plate small piece, and the blade-proof plate small piece has a connecting hole. A plurality of blade-preventing plate pieces, each of which has an upper surface protruding portion and a lower-face protruding portion overlapping each other, and has a total thickness of two plate-shaped small pieces, and has no empty surface. Forming a sheet-like first layer consisting of a group, the second layer formed in the same manner, the upper and lower permeation void points that appeared during the formation of each layer mutually covered with the surface of the blade plate small pieces, Slide and stack, and insert the headed stopper in the connecting hole of both layers that overlap at the shifted position of both layers. The two layers are interconnected in a state where there is play in both the thickness direction and the plane direction, and the blade plate pieces of each layer achieve the connection between the blade plate pieces of the other layer. A base cloth is interposed when the layer and the second layer are laminated.

<Operation> In the present invention, each small piece of the blade plate has a protruding portion, and the small pieces are abutted against each other to form a layer in a state where the protruding portions overlap each other. That is, even if each piece is slightly moved in the separating direction, no true gap is formed as long as the upper and lower protruding portions do not slide down. Also, the geometrical upper and lower transmission void points that appear when abutting small pieces to form a layer are shifted so that they do not overlap when the first layer and the second layer are laminated, so that the two layers are laminated. There are no geometrical void points in any part of the protective material. Further, since the connection of each layer is achieved by a headed stopper, even if a play is formed both in the axial direction of the stopper and in the direction orthogonal to the axis (plane direction), the stopper head is prevented from being pulled out and the head is removed. The part is a blade against thin blades,
That is, it prevents the generation of voids.

Furthermore, the base fabric interposed between the two layers serves as a cushioning function between the two layers, prevents the generation of unpleasant noise due to rattling of each small piece, and maintains a constant interval between each layer, so that when the blade is pierced Dissipation of penetration energy.

<Embodiment> (1) The blade plate small piece (1) shown as a plan view in FIG. 1B and as a front view in FIG. 1C has hexagonal shapes A, B, C, D, which are symmetrical vertically and horizontally. E, F and hexagon A ', B',
C ', D', E ', F'are congruent, Is formed by shifting the upper hexagon in the lateral direction to form an integrated shape and integrally forming plastic or bonding two members.

Hexagonal vertical center line ▲ ▼ and horizontal line ▲ ▼ and ▲
The intersections with ▼ are marked as O and O, respectively, and the same line ▲
The intersection of ▼ and the horizontal lines ▲ ▼ and ▲ ▼ is O ',
Let O ′ be the intersections of the sides of both hexagons on the vertical center line L of the blade plate, L ₁ and L _2, and the intersections with the lines ▲ ▼ and ▲ ▼ are O ₁ and O ₂ , respectively: ▲ ▼ = ▲ ▼ ＝ ▲ ▼ ＝ ▲ ▼: 2
0 mm, ▲ ▼ ＝ ▲ ▼ (＝ ▲ ▼ ＝ ▲
▼): 40 mm, ▲ ▼ ＝ ▲ ▼ (＝ ▲ ▼ ＝ ▲
▼): 20mm, ▲ ▼ ＝ ▲ ▼: 60mm ▲ ▼ ＝ ▲ ▼ ＝ ▲ ▼ ＝ ▲ ▼ ＝ ▲
▼: A 10 mm geometrical plane shape is formed, and connecting holes a, b, c, and d are formed on the small blade plate on the lines BF ′ and CE ′, respectively. (= 15mm) at each line ▲ ▼, ▲ ▼, ▲
A diameter of 4 mm was set at the midpoint of ▼ and ▲ ▼.

As the plate material, a 1.5-2 mm thick plate of polycarbonate or a 1.5-2 mm thick plate containing 43% of nylon 66 glass fiber is used as a unit hexagonal plate. It is shifted like 3 to 4 in the center.
A small piece of the blade plate having a thickness of 1.5 mm and the left and right protruding portions (1 ', 1 ") having a thickness of 1.5 to 2 mm was integrally formed or bonded by two pieces.

Next, as shown in FIG. 1A, the small pieces of the blade plate are placed in such a manner that the upper surface protruding portions (1 ′) are placed on the lower surface protruding portions (1 ″), and the entire desired area is spread and the first layer ( B ₁₎ was formed. void point X in the presence position of the point L _1, L ₂ of the respective small pieces because it is abutting the edges of each piece group in this state has appeared.

Further, the blade protection plate small piece group layer having the same structure as the first layer (B ₁ ) and represented by a wavy line is the second layer (B ₂ ), and the void point X of the first layer is the second layer as shown in FIG. So that the connecting holes of each layer are superposed, that is, the holes of the second layer and the holes of the first layer are respectively shifted as shown in FIG. 1A (a, c).
Both layers were laminated so as to polymerize with (b), (c), (c), (c), and (c) from the head (3) and the axis (4) as shown in the enlarged view of FIG. 3A. The hollow rivet was caulked to have a play of about 2 mm in the vertical direction (axial direction of the rivet) and about 1 mm in the plane direction (direction orthogonal to the rivet axis), and the two layers were connected by caulking.

The obtained laminated protective material is deformed in the vertical direction and the surface direction due to the fact that the connecting parts are scattered near the periphery of each small piece with respect to bending and are connected in a state with play, and the resulting flexible structure is flexible. Showed sex.

In addition, the presence of the respective protruding portions (1 ′, 1 ″) also prevented the generation of voids due to the surface direction movement deformation of each small piece.

(2) Using the same small piece of blade plate as used in Example 1, only the connecting hole group was modified. That is, as is apparent from FIGS. 2B and 2C, the connecting hole E is at the midpoint of the line ▲, the connecting hole is at the intersection O ′ of the line ▲ and the line ▲, and the line ▲ ▼. When the intersection of the line ▼▼ is O, the hole is the middle point of the line ▲ ▼ and the hole is the line ▲ ▼.
I set it at the middle point. That is, the connecting hole F in this embodiment corresponds to the hole B in the first embodiment, and the hole G corresponds to hole C.

Next, as in the first embodiment, each small piece group is spread and the first layer (B
₁ ) is formed, and the second layer forms each void point X on the first layer by reversing the top and bottom of each small group of the first layer, that is, by turning the surface over or rotating the surface by 180 °. As shown in FIG. 2A, for example, the connecting hole E of the second layer is used as the hole E of the first layer, and the hole F of the second layer is used as the hole E, and the hole F for the hole is similarly used as shown in FIG. 2A. The resin was polymerized into the holes and connected by rivets as in the first embodiment.

The protective material thus obtained had fewer supporting points than those of the first embodiment, and since it was supported at three points, the movement between the small pieces became smoother and the production was easier.

(3) In forming the human body protective material of Examples 1 and 2, an intermediate sheet having a cushioning function as shown in FIG. 3B, for example, a bulletproof chemical fiber sheet (F) is interposed between the first layer and the second layer. Then, the first layer and the second layer were rivet-connected with each other in a state where there was considerable play in the rivet axial direction and the axis orthogonal direction.

In the obtained protective material, as a result of the intermediate sheet functioning as a cushioning material, the rivet axial distance between the first layer (B ₁ ) and the second layer (B ₂ ) is considerably increased, and the rattling of the small pieces is increased. However, the unpleasant noise can be prevented and the flexibility of the entire protective material is increased because the distance between the two layers is increased. Also, since the intermediate sheet layer is interposed between the two layers, in the experiment of piercing a thin blade, the play connection between the small pieces of the plate and the play between the two layers are large,
Moreover, due to the three-layer structure of the different materials, a high blade-proof function was exhibited by the energy dissipation at the time of starting the insertion of the blade and at the time of reaching each interface rushing from the first layer to the base layer and the second layer.

In addition, the bulletproof chemical fiber sheet itself, which is an intermediate sheet,
The high-density sheet structure of fibers with a large Young's modulus absorbs the blade piercing energy as frictional energy considerably, and a mounting piece such as a belt is attached to the end of the sheet, which is convenient for mounting protective materials. Since the small pieces of the blade-preventing material are attached to the intermediate sheet, the protective sheet is inserted into a vest-shaped bag in terms of manufacturing and handling the human body-protecting material, which is convenient and convenient.

As described above in detail with reference to the three embodiments, for example, two small pieces of the blade plate as shown in FIG. 4 are vertically and laterally displaced to form the protruding portion (1,1 ″), which is connected to each other. The present invention can be practiced even if the holes a ', b', c ', and d'are provided, and the blade has a particularly excellent blade-preventing function for a specific portion of the protective material, for example, a portion for protecting the heart. It is within the scope of the present invention to apply a small piece, to increase the fit property to the human body by placing each piece of the blade plate slightly curved so as to follow the shape of the human body, and the like within the scope of the present invention. It will be obvious.

<Effects of the Invention> As described above, the present invention produces an advantageous effect which cannot be obtained by a conventional product due to its configuration, and when used as a human body protection garment, it is a trade-off between blade-proof function and clothing characteristics. We have provided products that can meet both of your needs.

That is, it has been achieved that the blade plate material is divided into small pieces to provide the fit property to the human body as a whole.

Since the small pieces are play-connected in such a manner that the protruding portions overlap each other, even if the small pieces move to a considerable extent, no gap is formed in the protective material surface due to the protruding portions, which allows the insertion of the cutting tool.

In order to form the thickness of the blade plate required for blade protection function with multiple sheets, for example, the required thickness of 4 mm is 2 more than when formed with a single plate.
When two sheets with a thickness of mm are formed in a relationship allowing rattling, the energy of the cutting tool is dissipated at the boundary where the cutting tool acts from the first layer to the second layer. The blade protection function has been improved.

Since the intermediate sheet is interposed between the first blade layer and the second blade layer, it is possible to prevent unpleasant noises from being generated due to the rattling of each small piece while at the same time, in terms of the blade preventing function, By forming a sufficient space between both layers when penetrating from the layer to the second layer, diffusion and disappearance of the working energy of the blade became remarkable.

Since the base cloth formed a constant interval between the first blade layer and the second blade layer, the breathability and the hygroscopicity were remarkably improved.
