Further, the above Patent Document 2 is an invention related to a bulletproof vest, and has the merit of being able to provide a bulletproof vest that is lightweight and has high performance in protecting the body from projectiles. However, in the conventional stab-proof vests as shown in Patent Document 1 above, those having only stab-proof performance are common, and the development of those having bullet-proof performance as well has been desired. Similarly, in the conventional bullet-proof vests as shown in Patent Document 2 above, those having only bullet-proof performance are common, and the development of those having stab-proof performance as well has been desired. In particular, when it is assumed that unexpected accidents or incidents may occur within facilities such as schools, hospitals, companies, etc., or within means of transportation such as trains and buses, or during commuting or going to school, the development of protective equipment having both stab-proof and bullet-proof performance is expected.

[0005] Therefore, the present invention solves the above-mentioned conventional problems, has three protective performances of stab-proof, puncture-proof, and bullet-proof, has sound insulation, and has flexibility in both the vertical and horizontal directions, so that it can be used without hindering movement.

Further, the manufacturing method of the storage space forming body of the present invention is a manufacturing method of the storage space forming body that constitutes the first defense body in the anti-blade, anti-stab, and bulletproof tool according to claim 1. A rectangular single sheet-like member made of a polyamide-based resin is prepared, and the widths of a pair of adjacent fold lines alternate between large and small, and the width of the larger pair of adjacent fold lines is about 105% to 125% of the width of the plate, and the width of the smaller pair of adjacent fold lines is about 30% to 60% of the width of the plate. The sheet-like member is zigzag-folded along a plurality of fold lines arranged in parallel in the longitudinal direction of the sheet-like member. In the vicinity of the fold line arranged on the back surface side of the sheet-like member, the folded sheet-like member is sewn over the entire length of the fold line. In the vicinity of the fold line arranged on the front surface side of the sheet-like member, the folded sheet-like member and the sheet-like member overlapping therebelow are sewn over the entire length of the fold line, thereby forming a partition piece for partitioning a plurality of storage spaces on the back surface side of the sheet-like member. A partition piece forming step, and a predetermined region of the sheet-like member in which a plurality of partition pieces are formed by the partition piece forming step is folded back to the back surface side of the sheet-like member at a fold line orthogonal to the partition piece, and the folded sheet-like member in the vicinity of the fold line is sewn over the entire length of the fold line.

Effects of the Invention

[0007] According to the anti-blade, anti-stab, and bulletproof tool with the above first feature, by adopting a configuration including two types of protective bodies, namely, a first protective body for storing plates and a second protective body having a ultra-high molecular weight polyethylene layer formed by laminating a plurality of sheet-like fabrics made of ultra-high molecular weight polyethylene, an anti-blade, anti-stab, and bulletproof tool with three protective performances of anti-blade, anti-stab, and bulletproof can be obtained. Further, since the storage space forming body constituting the first protective body has a plurality of storage spaces capable of individually storing a plurality of plates, it is possible to surely prevent the plates from directly contacting each other, and an anti-blade, anti-stab, and bulletproof tool rich in sound insulation can be obtained. Also, when using a metal plate having spring properties as the plate, it has flexibility in both the vertical and horizontal directions and also has a restoring force, so that it can fit the body and be used without hindering movement. Moreover, it can be an anti-blade, anti-stab, and bulletproof tool with less metal deformation and high durability. In addition, as the configuration of the storage space for storing the plates, a plurality of storage spaces are arranged in parallel so that adjacent storage spaces have an overlapping portion with a predetermined width. Thus, the plurality of plates stored in the first protective body can be laminated at the overlapping portion, and an anti-blade, anti-stab, and bulletproof tool with even higher protective performance can be obtained. Furthermore, as the configuration of the second protective body, by providing a waterproof sheet layer covering the entire surface of the synthetic resin layer, it is possible to surely prevent the synthetic resin layer from being hydrolyzed and causing a strength reduction, and an anti-blade, anti-stab, and bulletproof tool with even higher durability can be obtained.

[0008] Also, according to the anti-blade, anti-stab, and bulletproof tool with the above second feature, in addition to the effects of the above first feature, by adopting a configuration in which a single sheet-like member folded in a bellows shape is used as the configuration of the storage space forming body, a storage space forming body that is easy to manufacture and in which the positioning of a plurality of plates is easy can be obtained. Therefore, an anti-blade, anti-stab, and bulletproof tool with good manufacturing efficiency can be obtained. Also, by adopting a configuration in which a sheet-like member made of a polyamide-based resin is used as the single sheet-like member, a storage space forming body with high strength and high durability can be obtained.

[0009] Moreover, according to the anti-blade, anti-stab, and bulletproof equipment with the above third feature, in addition to the effects of the above first or second feature, the protective area can be effectively expanded, and all the storage spaces of adjacent storage space formers have overlapping portions of a predetermined width, so that the anti-blade, anti-stab, and bulletproof equipment with even higher protective performance can be obtained.

[0010] Furthermore, according to the anti-blade, anti-stab, and bulletproof equipment with the above fourth feature, in addition to the effect of the above first feature, by adopting a configuration using a storage bag formed of a sheet-like member made of a polyamide-based resin, a storage bag with high strength and high durability can be obtained.

[0011] Also, according to the manufacturing method of the storage space former with the above fifth feature, in the partition piece forming step, by simply zigzag folding and sewing a single sheet-like member along a plurality of fold lines, partition pieces for partitioning a plurality of storage spaces can be formed on the back side of the single sheet-like member. Further, in the folding and sewing step, a bottom that can prevent the plate from falling when the plate is stored in each storage space can be formed. By adopting a configuration including these steps, a plurality of plates can be individually stored in each of the plurality of storage spaces, the positioning of the stored plates is easy, and a storage space former that can reliably hold the stored plates can be manufactured. Also, it can be a manufacturing method of a storage space former with good manufacturing efficiency.

[0012] Moreover, according to the manufacturing method of the first protective body with the above sixth feature, in the storage space temporary fixing step, the base and the storage space former can be integrated, and the storage operation of each plate into each storage space in the subsequent plate storage step can be performed easily and efficiently. Also, in the storage space former fixing step, the storage space former can be completely fixed to the base with each plate stored in each storage space. By adopting a configuration including these steps, it can be a manufacturing method of the first protective body with good manufacturing efficiency.

Embodiments for Carrying Out the Invention

[0014] Hereinafter, with reference to the respective drawings, an anti-blade, anti-stab, and bulletproof tool according to an embodiment of the present invention, a method for manufacturing a storage space forming body that constitutes a first defense body in the anti-blade, anti-stab, and bulletproof tool, and a method for manufacturing a first defense body that constitutes the anti-blade, anti-stab, and bulletproof tool will be described to aid in understanding the present invention. However, the following description does not limit the present invention described in the claims.

[0015] First, referring to FIGS. 1 to 6, an anti-blade, anti-stab, and bulletproof tool 1 according to an embodiment of the present invention is used to protect the body from attacks by knives such as a knife or an ice pick, attacks by a gun, or to protect the body under circumstances where it can receive impacts equivalent thereto. Note that this anti-blade, anti-stab, and bulletproof tool can be used, for example, not only by being incorporated into a so-called anti-blade vest or bulletproof vest, but also by being incorporated into a children's backpack or schoolbag, or by being incorporated into a women's shoulder bag or business bag, etc., and can be used according to various applications. In addition, the broken lines in FIGS. 1 to 4, 7, and 8 indicate sewing lines, and in FIGS. 2(b), 5, and 6(a), for the sake of convenience of explanation, the sewing lines are not shown.

[0016] As shown in FIG. 1, this anti-blade, anti-stab, and bulletproof tool 1 is composed of a first defense body 10, a buffer body 20, a second defense body 30, and a storage bag 40.

[0017] The first defense body 10 constitutes a so-called first defense layer in the anti-blade, anti-stab, and bulletproof tool 1 for protecting the body from attacks by knives, guns, etc. Specifically, from the viewpoints of anti-blade and anti-stab, it is for reducing the initial velocity of a knife such as a knife or an ice pick and stopping the force of the knife. Also, from the viewpoint of bulletproof, it is for reducing the initial velocity of a bullet and flattening the shape of the bullet to increase the area of the bullet. As shown in FIGS. 2 and 3, this first defense body 10 is composed of a base 11, a storage space forming body 12, and a plate 13.

[0018] The base 11 forms the framework of the first protector 10 and serves as a base for sewing the storage space former 12. Also, from the viewpoints of blade defense and stab defense, it plays an auxiliary role in reducing the initial velocity of a blade such as a knife or an ice pick and stopping the force of the blade. Also, from the viewpoint of bulletproofing, it plays an auxiliary role in increasing the area of a bullet by reducing the initial velocity of the bullet and deforming the shape of the bullet into a flat shape. In the present embodiment, the base 11 is configured to be formed of a hexagonal sheet-like member with the left and right ends of the upper rectangular side cut off. Also, as the sheet-like member, a configuration is adopted in which a single sheet-like member made of a polyamide-based resin with a thickness of about 5 mm is used. Furthermore, a resin coating capable of adding an anti-slip function is applied to the surface of the single sheet-like member made of a polyamide-based resin where the storage space former 12 is sewn. Note that the shape, size, and thickness of the base 11 are not limited to those of the present embodiment and can be changed as appropriate.

[0019] The storage space former 12 is a member that, by being sewn to the base 11, cooperates with the base 11 to form a space for storing and holding the plate 13. Also, from the viewpoints of blade defense and stab defense, it plays an auxiliary role in reducing the initial velocity of a blade such as a knife or an ice pick and stopping the force of the blade. Also, from the viewpoint of bulletproofing, it plays an auxiliary role in increasing the area of a bullet by reducing the initial velocity of the bullet and deforming the shape of the bullet into a flat shape.

[0020] In the present embodiment, as the storage space former 12, a sheet-like member is used which has a plurality of storage spaces capable of individually storing a plurality of plates 13, and the plurality of storage spaces are arranged in parallel in the horizontal direction such that adjacent storage spaces have overlapping portions of a predetermined width. Specifically, as shown in FIG. 4, there are six storage spaces including a first storage space 12a, a second storage space 12b, a third storage space 12c, a fourth storage space 12d, a fifth storage space 12e, and a sixth storage space 12f, each of which can individually store six plates 13 (a first plate 13a, a second plate 13b, a third plate 13c, a fourth plate 13d, a fifth plate 13e, and a sixth plate 13f). A plurality of storage spaces (12a to 12f) are arranged in parallel in the horizontal direction such that adjacent storage spaces have an overlapping portion C of a predetermined width indicated by hatching in FIG. 5(a). Also, in the present embodiment, the four storage spaces of the second storage space 12b to the fifth storage space 12e have the same size, and the two storage spaces of the first storage space 12a and the sixth storage space 12f are configured to have a slightly larger lateral width than the four storage spaces for the purpose of ensuring a sewing margin with the base 11. Note that the shape, size, and number of the storage spaces of the storage space forming body 12 are not limited to those of the present embodiment and can be appropriately changed.

[0021] Note that the overlapping portion C indicated by hatching in FIG. 5(a) indicates the overlapping portion in the area where the plate 13 can be stored except for the sewing portion. That is, the "storage space" in the present invention indicates the space where the plate 13 can be stored. Also, the above "predetermined width" is preferably about 15% to 50% of the lateral width of the plate 13 shown in FIG. 4(a). More specifically, when the lateral width of the plate 13 is about 6 cm, the predetermined width is preferably about 1 cm to 2.5 cm. Also, as shown in FIGS. 3 and 4, the storage space forming body 12 in the present embodiment includes a partition piece S for partitioning each storage space and a folding portion R for forming a bottom for preventing the plate 13 stored in the storage space from falling. Although not shown in detail, this folding portion R is formed by integrally folding the lower region of the storage space forming body 12 to the back side. Note that the "back side" means that in the storage space forming body 12, the side in contact with the plate 13 is the back side, and the side not in contact with the plate 13 is the front side.

[0022] Also, in the present embodiment, as shown in FIGS. 2, 3, 5(b), and 6(a), the first protector 10 includes a plurality of storage space formers 12, and the plurality of storage space formers 12 are arranged in parallel in the vertical direction such that all the storage spaces of adjacent storage space formers 12 have an overlapping portion of a predetermined width. Specifically, as shown in FIGS. 2(b) and 3, it includes four storage space formers: the first-stage storage space former 12g, the second-stage storage space former 12h, the third-stage storage space former 12i, and the fourth-stage storage space former 12j, and the plurality of storage space formers (12g to 12j) are arranged in parallel in the vertical direction such that all the storage spaces (12a to 12f) of adjacent storage space formers 12 have an overlapping portion D of a predetermined width shown by hatching in FIG. 5(b). Here, the "predetermined width" is desirably about 9% to 50% of the vertical width of the plate shown in FIG. 4(a). More specifically, when the vertical width of the plate is about 10.7 cm, the predetermined width is desirably about 1 cm to 3 cm.

[0023] Also, in the present embodiment, as shown in FIG. 3, the first-stage storage space former 12g and the second-stage storage space former 12h are storage space formers having the same shape and size. Further, the third-stage storage space former 12i and the fourth-stage storage space former 12j are shaped such that the upper parts at both left and right ends are cut off obliquely according to the shape of the base 12. Of course, the number, shape, size, and arrangement position of the storage space formers 12 are not limited to such a configuration and can be changed as appropriate. Furthermore, although not shown in detail, in the four storage space forming members (storage space forming members 12g to 12j), the first-stage storage space forming member 12g has its four peripheral sides sewn to the base 11. Also, for the second-stage storage space forming member 12h, three sides excluding the lower side that overlaps with the plate 13 stored in the first-stage storage space forming member 12g are sewn to the base 11. For the third-stage storage space forming member 12i, five sides excluding the lower side that overlaps with the plate 13 stored in the second-stage storage space forming member 12h are sewn to the base 11. And for the fourth-stage storage space forming member 12j, five sides excluding the lower side that overlaps with the plate 13 stored in the third-stage storage space forming member 12i are sewn to the base 11. With such a configuration, at the positions of the lower sides of the second-stage storage space forming member 12h, the third-stage storage space forming member 12i, and the fourth-stage storage space forming member 12j, the first protective body 10 is configured to be bendable to a certain extent toward the rear side. Here, "rear" means that in the first protective body 10 shown in FIG. 2, the side of the base 11 is the rear and the side of the storage space forming member 12 is the front.

[0024] As described above, it includes six storage spaces, namely the first storage space 12a, the second storage space 12b, the third storage space 12c, the fourth storage space 12d, the fifth storage space 12e, and the sixth storage space 12f, each capable of individually storing six plates 13. A plurality of storage spaces (12a to 12f) are arranged in parallel in the horizontal direction such that adjacent storage spaces have an overlapping portion C shown by hatching in FIG. 5(a). And it includes four storage space forming members, namely the first-stage storage space forming member 12g, the second-stage storage space forming member 12h, the third-stage storage space forming member 12i, and the fourth-stage storage space forming member 12j. A plurality of storage space forming members (12g to 12j) are arranged in parallel in the vertical direction such that all the storage spaces (12a to 12f) of adjacent storage space forming members 12 have an overlapping portion D shown by hatching in FIG. 5(b). With such a configuration, as shown in FIG. 6, in the first protective body 10 in this embodiment, there is no area where the plate 13 is not arranged, and it can be configured to have four areas, namely an area where only one plate 13 is arranged, an area where two plates are stacked, an area where three plates are stacked, and an area where four plates are stacked.

[0025] In this embodiment, the storage space forming body 12 described above is formed of a single sheet-like member made of a polyamide-based resin, which is pleated along a plurality of fold lines where the widths of a pair of adjacent fold lines alternately repeat between large and small, and the width of the larger pair of adjacent fold lines is about 105% to 125% of the width of the plate 13, and the width of the smaller pair of adjacent fold lines is about 30% to 60% of the width of the plate 13, and a predetermined position is sewn in a pleated state. In addition, a resin coating capable of adding an anti-slip function is applied to the back surface of the single sheet-like member made of a polyamide-based resin.

[0026] From the viewpoints of blade prevention and stab prevention, the plate 13 mainly serves to reduce the initial velocity of a blade such as a knife or an ice pick and stop the force of the blade. From the viewpoint of bulletproof, it mainly serves to increase the area of the bullet by reducing the initial velocity of the bullet and flattening the shape of the bullet. In this embodiment, as the plate 13, a vertically long substantially rectangular manganese steel having spring properties is used. Also, as shown in FIGS. 3 and 4(a), the plate 13 having curved and chamfered corners is used. More specifically, a configuration is adopted in which a manganese steel (a metal plate having spring properties) having spring properties with a vertical length of about 10.7 cm, a horizontal length of about 6 cm, and a thickness of about 0.5 mm is used. Of course, the material, shape, size, and thickness of the plate 13 are not limited to those of the present embodiment and can be appropriately changed. For example, the material of the plate 13 is not limited to manganese steel, and a configuration using other metal plates having spring properties may be adopted. Alternatively, instead of a metal plate, a synthetic resin plate (for example, a glass fiber reinforced plastic plate or a carbon fiber reinforced plastic plate) or a ceramic plate may be used, or a configuration in which at least any two of a metal plate, a synthetic resin plate, and a ceramic plate are combined may be adopted. However, when using a ceramic plate, it is necessary to consider that the flexibility of the plate 13 is reduced. Therefore, considering the protection performance, weight, and flexibility of the first protector 10, it is desirable to adopt a configuration in which the material is manganese steel and the thickness is about 0.5 mm. As shown in FIG. 3, the size and shape of the plurality of plates 13 are such that they can be stored in the respective storage spaces of the first-stage storage space forming body 12g, the second-stage storage space forming body 12h, the third-stage storage space forming body 12i, and the fourth-stage storage space forming body 12j with a gap of about 10 mm or less.

[0027] The buffer body 20 serves as a cushioning material in the anti-blade, anti-stab, and anti-ballistic tool 1 and is for reducing the rubbing noise between the first protector 10 and the second protector 30. In the present embodiment, a configuration is adopted in which a flame-retardant sponge having the same shape and size as the base 11 is used as the buffer body 20. It should be noted that the thickness of the buffer body 20 is preferably about 5 mm, but is not limited to such a configuration, and the thickness, shape, size, number, and material of the buffer body 20 can be appropriately changed.

[0028] The second protective body 30 is disposed on the rear side of the first protective body 10 and constitutes a so-called second protective layer for protecting the body from attacks by knives and guns in the knife-proof, stabbing-proof, and bullet-proof tool 1. As shown in FIG. 6(b), this second protective body 30 is composed of a synthetic resin layer 31 and a waterproof sheet layer 32.

[0029] From the viewpoints of knife-proof and stabbing-proof, the synthetic resin layer 31 is for preventing fragments scattered when a knife such as a knife or an ice pick chips or the plate 13 is damaged from penetrating the knife-proof, stabbing-proof, and bullet-proof tool 1. Also, from the viewpoint of bullet-proof, it is for wrapping the bullet whose area has increased with the first protective body 10 and preventing the bullet from penetrating the knife-proof, stabbing-proof, and bullet-proof tool 1. Furthermore, it serves as a cushioning material in the knife-proof, stabbing-proof, and bullet-proof tool 1. In the present embodiment, as shown in FIGS. 6(b) and 6(c), the synthetic resin layer 31 includes a ultra-high molecular weight polyethylene layer 31a formed by laminating a plurality of sheet-like woven fabrics made of ultra-high molecular weight polyethylene, and a urethane resin layer 31b made of a sheet formed of urethane resin. Note that the ultra-high molecular weight polyethylene layer 31a is configured by laminating 26 sheet-like woven fabrics made of ultra-high molecular weight polyethylene with a thickness of about 0.3 mm and woven in a single direction. The number of laminated sheet-like woven fabrics made of ultra-high molecular weight polyethylene is not limited to that of the present embodiment. However, when using a sheet-like woven fabric made of ultra-high molecular weight polyethylene with a thickness of about 0.3 mm and woven in a single direction, considering the protection performance, weight, price, etc., about 20 to 26 sheets are desirable, and more preferably 26 sheets. Also, as the urethane resin layer 31b, it is desirable to use a sheet formed of urethane resin with a thickness of about 3 mm. Of course, the thickness of the urethane resin layer 31b is not limited to such a configuration and can be appropriately changed.

[0030] The waterproof sheet layer 32 is for sealing the synthetic resin layer 31 to prevent hydrolysis from occurring in the synthetic resin layer 31. In this embodiment, a hot melt adhesive is used to coat the entire surface of the synthetic resin layer 31 with a waterproof sheet material of a predetermined thickness (about 0.5 mm in this embodiment) that is commonly used.

[0031] The storage bag 40 constitutes a so-called cover for storing the first protector 10, the buffer 20, and the second protector 30 in a stacked state. In this embodiment, a sheet-like member made of the same polyamide-based resin as the base 11 and the storage space former 12 is used to form a first part that constitutes the front surface of the storage bag 40, a second part that constitutes the back surface, a third part that connects the front surface and the back surface and constitutes the side surface and the upper surface, and a fourth part that constitutes the cover lid. By sewing these four parts together, a storage bag 40 is formed that is slightly larger in shape than the first protector 10, the buffer 20, and the second protector 30. Also, the width in the short direction of the third part that constitutes the side surface and the upper surface formed of an elongated strip-like member is set to be approximately the same as or slightly larger than the thickness obtained by stacking the three of the first protector 10, the buffer 20, and the second protector 30. As shown in FIG. 1, this storage bag 40 has an opening 41 on the lower surface. The first protector 10, the buffer 20, and the second protector 30 are inserted through this opening 41, and the cover lid is closed with a Magic Tape (registered trademark) M attached to each of the main body and the cover lid. Furthermore, the inner surface of the storage bag 40 is provided with a resin coating that can add an anti-slip function.

[0032] Next, a manufacturing method of the anti-blade, anti-stab, and anti-bullet tool 1 having such a configuration will be described.

[0033] First, a manufacturing method of the first protector 10 will be described. Referring to FIG. 3, a base 11 formed of a sheet-like member made of a polyamide-based resin having a predetermined shape and size is prepared. Next, in the partition piece forming step, a horizontally long rectangular single sheet-like member 120 made of a polyamide resin shown in Fig. 7(a) is prepared. At this time, as shown in Fig. 7(a), a first back surface folding line B is provided at an interval of about 105% to 125% of the lateral width of the plate 13 from the left end side in the longitudinal direction of the sheet-like member 120. From this first back surface folding line B toward the right end side of the sheet-like member 120, a pair of smaller adjacent folding lines having a length of about 30% to 60% of the lateral width of the plate 13 and a pair of larger adjacent folding lines having a length of about 105% to 125% of the lateral width of the plate 13 are provided alternately (in this embodiment, 5 front surface folding lines F and 4 back surface folding lines B are provided). It is necessary to prepare a single sheet-like member 120 capable of providing a right end side in the longitudinal direction of the sheet-like member 120 with an interval of about 105% to 125% of the lateral width of the plate 13 from the rightmost folding line (in this embodiment, the front surface folding line F arranged on the rightmost side). In this embodiment, as shown in Fig. 7(a), the width H from the left end side of the sheet-like member 120 to the first back surface folding line B is about 127% of the lateral width of the plate 13 (about 7.6 cm), the width E from the back surface folding line B, which is the width of a pair of smaller adjacent folding lines, to the front surface folding line F is about 60% of the lateral width of the plate 13 (about 3.6 cm), the width G from the front surface folding line F, which is the width of a pair of larger adjacent folding lines, to the back surface folding line B is about 118% of the lateral width of the plate 13 (about 7.1 cm), and the width I from the front surface folding line F arranged on the rightmost side to the right end side of the sheet-like member 120 is about 127% of the lateral width of the plate 13 (about 7.6 cm). A sheet-like member 120 is prepared.

[0034] Then, as shown in FIG. 7(a), on such a sheet-like member 120, a back surface fold line B and a front surface fold line F are drawn on the back surface and the front surface, respectively, such that the widths of a pair of adjacent fold lines alternate between large and small. More specifically, in the present embodiment, the back surface fold line B shown by the dashed line in FIG. 7(a) is drawn on the back surface of the sheet-like member 120, and the front surface fold line F shown by the two-dot chain line in FIG. 7(a) is drawn on the front surface of the sheet-like member 120. Of course, the present invention is not limited to such a configuration, and all the fold lines may be drawn on the back surface or the front surface. However, in this case, it is desirable to adopt a configuration that allows the distinction between the back surface fold line and the front surface fold line to be easily made visually.

[0035] Thereafter, as shown in FIG. 7, the sheet-like member 120 is pleated in the longitudinal direction along a plurality of fold lines from the left end to the right end in the longitudinal direction of the sheet-like member 120. Specifically, the sheet-like member 120 is mountain-folded along a plurality of fold lines so that each fold line comes to the outside of the sheet-like member 120, thereby pleating the sheet-like member 120 in the longitudinal direction. Thereafter, in the vicinity of the back surface fold line B of the sheet-like member 120, the folded sheet-like member 120 is sewn over the entire length of the back surface fold line B, and in the vicinity of the front surface fold line F of the sheet-like member 120, the folded sheet-like member 120 and the sheet-like member 120 overlapping therebelow are sewn over the entire length of the front surface fold line F, thereby forming partition pieces S for partitioning a plurality of storage spaces on the back surface side of the sheet-like member 120. Here and hereinafter, the "vicinity position" means a position about 2 mm away from each fold line. As a result, the sheet-like member 120 is in the state shown in FIG. 7(d).

[0036] Next, referring to FIG. 8(a), by the folding and sewing process, a predetermined region (a folding region T disposed below) of the sheet-like member 120 in which a plurality of partition pieces S are formed by the partition piece forming process is folded to the back surface side of the sheet-like member 120 along a folding line L shown by a two-dot chain line orthogonal to the partition piece S. Then, in that state, the sheet-like member 120 folded in the vicinity of the fold line L is sewn along the entire length of the fold line L. As a result, the sheet-like member 120 assumes the state shown in Fig. 8(b), and the first-stage storage space forming body 12g is formed. Note that since the second-stage storage space forming body 12h, the third-stage storage space forming body 12i, and the fourth-stage storage space forming body 12j can also be manufactured by the same manufacturing method as that of the first-stage storage space forming body 12g, the following detailed description will be omitted.

[0037] Thereafter, referring to Fig. 8(b), in the storage space temporary fixing step, in the sheet-like member (the first-stage storage space forming body 12g) in which the folding region T is folded, the vicinity position U of the tip shown by the thick line in Fig. 8(b) on the side opposite to the fold line L of the folding region T is sewn to the base 11 by a length substantially the same as that of the fold line L, and among both end sides orthogonal to the fold line L of the sheet-like member (the first-stage storage space forming body 12g) excluding the folding region T, the end side V disposed on the lower layer side of the sheet-like member (the first-stage storage space forming body 12g) in the state of being pleated is sewn to the base 11 along the entire length of the end side V, thereby temporarily fixing the storage space forming body 12 to the base 11. Note that here and hereinafter, "substantially the same length" means a length of about 98% to 100% of the reference length.

[0038] Thereafter, referring to Fig. 8(b) and Fig. 8(c), in the plate storage step, the plates 13 are sequentially stored in each storage space from the storage space 12a on the end side V sewn to the base 11, and the vicinity position X of the tip shown by the oblique line in Fig. 8(c) on the side parallel to the end side V of each partition piece S is sewn to the base 11 up to the vicinity position U of the tip on the side opposite to the fold line L of the folding region T, and among both end sides orthogonal to the fold line L of the sheet-like member (the first-stage storage space forming body 12g) excluding the folding region T, the end side Y disposed on the upper layer side of the sheet-like member (the first-stage storage space forming body 12g) in the state of being pleated is sewn to the base 11 along the entire length of the end side Y, thereby storing a plurality of plates 13 in each storage space.

[0039] Subsequently, in the step of fixing the storage space forming body, the tip vicinity position W shown by the thick line in FIG. 8(b) on the side facing the folding line L of the sheet-like member (the first-stage storage space forming body 12g) excluding the folding region T is sewn to the base 11 by substantially the same length as the folding line L, and the vicinity position Z of the folding line L of the sheet-like member (the first-stage storage space forming body 12g) excluding the folding region T is sewn to the base 11 over the entire length of the folding line L, thereby completely fixing the first-stage storage space forming body 12 to the base 11.

[0039]

[0040] Subsequently, the second-stage storage space forming body 12h, the third-stage storage space forming body 12i, and the fourth-stage storage space forming body 12j are fixed to the base 11 in a state where the plate 13 is housed in the same manner as the method of fixing the first-stage storage space forming body 12 to the base 11. At this time, it is fixed to the base 11 so that the overlapping portion D shown by the oblique lines in FIG. 5(b) is formed.

[0040] In the second-stage storage space forming body 12h, the third-stage storage space forming body 12i, and the fourth-stage storage space forming body 12j, since there is an overlapping portion with the plate 13 housed in the storage space forming body arranged below each storage space forming body, the vicinity position Z shown by the thick line in FIG. 8(b) of the folding line L of the sheet-like member excluding the folding region T cannot be sewn to the base 11, so the sewing process for this portion is omitted. The first protector 10 is manufactured by the above steps.

[0041] Next, with reference to FIGS. 6(b) and 6(c), a method for manufacturing the second protector 30 will be described.

[0041]

[0042] First, with reference to FIG. 6(c), 26 sheets of a sheet-like fabric made of ultra-high molecular weight polyethylene with a thickness of about 0.3 mm and having the same shape and size as the first protector 10 are laminated to form an ultra-high molecular weight polyethylene layer 31a. Then, prepare a sheet formed of a urethane resin having a predetermined shape, predetermined size, and predetermined thickness that constitutes the urethane resin layer 31b. In this embodiment, the shape and size of the sheet formed of the urethane resin are the same as those of the sheet-like fabric made of ultra-high molecular weight polyethylene, and a sheet having a thickness of about 3 mm is prepared. Thereafter, prepare a general-purpose waterproof sheet material with a thickness of about 0.5 mm and a size that can cover the entire surfaces of the ultra-high molecular weight polyethylene layer 31a and the urethane resin layer 31b. Then, with reference to FIG. 6(b), in a state where the ultra-high molecular weight polyethylene layer 31a is laminated on the urethane resin layer 31b, use a hot melt adhesive to coat the entire surface of the synthetic resin layer 31 with the waterproof sheet material. Thereby, the second protector 30 is manufactured.

[0043] Then, as the buffer body 20, prepare a flame-retardant sponge having the same shape and size as the first protector 10 and a thickness of about 5 mm. With the above first protector 10, buffer body 20, and second protector 30 prepared, arrange the first protector 10, buffer body 20, and second protector 30 in the arrangement order shown in FIG. 1(b), and store the first protector 10, buffer body 20, and second protector 30 into the storage bag 40 from the opening 41 of the previously prepared storage bag 40, and adhere the magic tapes (registered trademarks) respectively attached to the main body and the cover. Through the above steps, the anti-blade, anti-stab, and anti-bullet tool 1 according to the embodiment of the present invention is manufactured. Note that the packaging bag 40 is formed using a sheet-like member made of ultra-high molecular weight polyethylene to form four parts: a first part that constitutes the front surface of the storage bag 40, a second part that constitutes the back surface, a third part that connects the front surface and the back surface and constitutes the side surface and the upper surface, and a fourth part that constitutes the cover. Sew these four parts together, and attach magic tapes (registered trademarks) to predetermined positions of the main body formed by the first part to the third part and the cover formed by the fourth part respectively, thereby manufacturing the packaging bag 40 having the opening 41.

[0044] The anti-blade, anti-stab, and bulletproof tool 1 according to the embodiment of the present invention having the above configuration and the manufacturing method of the anti-blade, anti-stab, and bulletproof tool 1 have the following effects.

[0045] By configuring two types of protective bodies, namely, a first protective body 10 that houses plates in a sheet-like member made of a polyamide-based resin and a second protective body 30 that includes a ultra-high molecular weight polyethylene layer 31a formed by laminating a plurality of sheet-like woven fabrics made of ultra-high molecular weight polyethylene, in a packaging bag 40 formed of a sheet-like member made of a polyamide-based resin, from the viewpoints of anti-blade and anti-stab, the initial velocity of a blade such as a knife or an ice pick can be reduced and the force of the blade can be stopped by four layers, namely, the front surface of the packaging bag 40, the storage space forming body 12, the plate 13, and the base 11. At the same time, when a blade such as a knife or an ice pick chips or when the plate 13 is damaged, the ultra-high molecular weight polyethylene layer 31a can prevent the scattered fragments from penetrating the anti-blade, anti-stab, and bulletproof tool 1. Also, from the viewpoint of bulletproof, the initial velocity of a bullet can be reduced and the shape of the bullet can be flattened by four layers, namely, the front surface of the packaging bag 40, the storage space forming body 12, the plate 13, and the base 11, so that the area of the bullet can be increased. At the same time, the ultra-high molecular weight polyethylene layer 31a can wrap the bullet with an increased area and prevent the bullet from penetrating the anti-blade, anti-stab, and bulletproof tool 1. Therefore, it is possible to obtain an anti-blade, anti-stab, and bulletproof tool 1 having three protective performances of anti-blade, anti-stab, and bulletproof.

[0046] In addition, since the storage space forming body 12 constituting the first protective body 10 includes a plurality of storage spaces (the first storage space 12a to the sixth storage space 12f) capable of individually storing a plurality of plates 13, it is possible to surely prevent the plates 13 from directly contacting each other, and an anti-blade, anti-stab, and bulletproof tool 1 rich in sound insulation can be obtained. In addition, as a configuration of the storage space for storing the plate 13, a plurality of storage spaces (the first storage space 12a to the sixth storage space 12f) are arranged in parallel in the horizontal direction such that adjacent storage spaces have an overlapping portion C of a predetermined width. Thus, a plurality of plates 13 stored in the first protector 10 can be stacked at the position of the overlapping portion C, and a cutting-resistant, stabbing-resistant, and bulletproof tool 1 with even higher protection performance can be obtained. In addition, as a configuration of the storage space forming body 12, by adopting a configuration using a single sheet-like member 120 that is bellows-folded, a storage space forming body 12 that is easy to manufacture and allows easy positioning of a plurality of plates 13 can be obtained. Therefore, a cutting-resistant, stabbing-resistant, and bulletproof tool 1 with good manufacturing efficiency can be obtained. Further, as a single sheet-like member, by adopting a configuration using a sheet-like member 120 made of a polyamide-based resin, a storage space forming body 12 with high strength and high durability can be obtained.

[0047] In addition, the first protector 10 includes a plurality of storage space forming bodies 12 (the storage space forming body 12g in the first stage to the storage space forming body 12j in the fourth stage), and a plurality of storage space forming bodies (the storage space forming body 12g in the first stage to the storage space forming body 12j in the fourth stage) are arranged in parallel in the vertical direction such that all the storage spaces of adjacent storage space forming bodies have an overlapping portion D of a predetermined width. Thus, the protection area can be effectively expanded. Also, since all the storage spaces of adjacent storage space forming bodies 12 have an overlapping portion of a predetermined width, a plurality of plates 13 stored in the first protector 10 can be stacked at the position of the overlapping portion D, and a cutting-resistant, stabbing-resistant, and bulletproof tool 1 with even higher protection performance can be obtained. In addition, there are provided six storage spaces including a first storage space 12a, a second storage space 12b, a third storage space 12c, a fourth storage space 12d, a fifth storage space 12e, and a sixth storage space 12f capable of individually storing six plates 13. A plurality of storage spaces (12a to 12f) are arranged in parallel in the horizontal direction such that adjacent storage spaces have an overlapping portion C shown by hatching in FIG. 5(a). Moreover, there are provided four storage space forming bodies including a first-stage storage space forming body 12g, a second-stage storage space forming body 12h, a third-stage storage space forming body 12i, and a fourth-stage storage space forming body 12j. A plurality of storage space forming bodies (12g to 12j) are arranged in parallel in the vertical direction such that all the storage spaces (12a to 12f) of adjacent storage space forming bodies 12 have an overlapping portion D shown by hatching in FIG. 5(b). With this configuration, as shown in FIG. 6, in the first protector 10 in the present embodiment, the plate 13 includes four regions: a region with only one plate, a region where two plates are stacked, a region where three plates are stacked, and a region where four plates are stacked. Moreover, the area occupied by the region with only one plate can be effectively suppressed. Therefore, it is possible to provide a blade-proof, stab-proof, and bullet-proof tool 1 with even higher protection performance.

[0048] Further, a resin coating with an anti-slip function is applied to the surface of the storage space forming body 12 on the base 11 that comes into contact with the plate 13 and the back surface of the sheet-like member forming the storage space forming body 12. This can effectively prevent the plate 13 from shifting, and it is possible to provide a blade-proof, stab-proof, and bullet-proof tool 1 that is excellent in sound absorption and can continuously maintain its protection performance. Furthermore, the lower sides of the second-stage storage space forming body 12h, the third-stage storage space forming body 12i, and the fourth-stage storage space forming body 12j are not sewn to the base 11. With a configuration such that the first protector 10 can be bent to a certain extent toward the rear side at the positions of the lower sides of the second-stage storage space forming body 12h, the lower side of the third-stage storage space forming body 12i, and the lower side of the fourth-stage storage space forming body 12j, it is easy to fit to the body and can be used without hindering movement, and it is possible to provide a blade-proof, stab-proof, and bullet-proof tool 1 with high mobility.

[0049] In addition, by using a metal plate 13 having spring properties, the plate has flexibility in both the vertical and horizontal directions and also has a restoring force, making it easier to fit the body more closely and enabling it to be used without hindering movement. Moreover, it can be made into a blade-proof, stab-proof, and bullet-proof tool 1 with less metal deformation and high durability. Also, by adopting a configuration using a plate 13 with curved and chamfered corners, it is possible to effectively prevent damage such as tearing from occurring in the storage space forming body 12 made of a sheet-like member of a polyamide-based resin, and to make it into a blade-proof, stab-proof, and bullet-proof tool 1 with high durability. In addition, even if the plate 13 is exposed to the outside from the storage space forming body 12, it is difficult for the user to be injured, and it is also possible to effectively prevent the manufacturer from being injured during manufacturing. Furthermore, by making the plate 13 into a vertically long substantially rectangular shape and configuring to individually store a plurality of plates 13 in a plurality of storage spaces respectively, compared with the case of using a horizontally long plate, it is easier to bend and can be made into a blade-proof, stab-proof, and bullet-proof tool 1 with higher mobility. In addition, if a configuration is adopted that combines at least any two of a metal plate, a synthetic resin plate, and a ceramic plate, it can be made into a blade-proof, stab-proof, and bullet-proof tool with even higher strength.

[0050] Also, by adopting a configuration in which a buffer body 20 made of a flame-retardant sponge is provided between the first protective body 10 and the second protective body 30, it is possible to reduce the rubbing noise between the first protective body 10 and the second protective body 30 and improve the cushioning performance of the blade-proof, stab-proof, and bullet-proof tool 1.

[0051] Furthermore, as the configuration of the second protective body 30, by providing a waterproof sheet layer 32 that covers the entire surface of the synthetic resin layer 31, it is possible to surely prevent the synthetic resin layer 31 from being hydrolyzed and causing a strength reduction, and to make it into a blade-proof, stab-proof, and bullet-proof tool 1 with even higher durability.

[0052] Moreover, by adopting a configuration that uses a storage bag formed of a sheet-like member made of a polyamide resin, a storage bag 40 with high strength and durability can be obtained. In addition, by applying a resin coating with an anti-slip function to the inner surface of the storage bag 40, it is possible to effectively prevent the displacement of the first protector 10 and the second protector 30 to be stored. Furthermore, by adopting a configuration in which the first protector 10, the buffer 20, and the second protector 30 are inserted through the opening 41 and the cover is closed with a Magic Tape (registered trademark) M attached to each of the main body and the cover, not only can the first protector 10, the buffer 20, and the second protector 30 be prevented from falling, but also the user can easily recognize that the side with the Magic Tape (registered trademark) M of the main body is the front side. As a result, it is possible to effectively prevent mistakes in the order when inserting the first protector 10, the buffer 20, and the second protector 30 into the storage bag 40, and mistakes in using the front side and the back side of the storage bag 40 during use, and a stab-proof, cut-proof, and bullet-proof tool 1 with high convenience for the user can be obtained.

[0053] Also, by means of a partition piece forming process, a partition piece S for partitioning a plurality of storage spaces on the back surface side of a single sheet-like member can be formed by simply zigzag folding and sewing a single sheet-like member with a plurality of fold lines. Further, by means of a folding and sewing process, a bottom capable of preventing the plate 13 from falling when the plate 13 is stored in each storage space can be formed. By adopting a configuration including these processes, a plurality of plates 13 can be individually stored in each of a plurality of storage spaces, the positioning of the plates 13 to be stored is easy, and a storage space forming body 12 capable of reliably holding the stored plates 13 can be manufactured. Also, a manufacturing method of the storage space forming body 12 with good manufacturing efficiency and a manufacturing method of the stab-proof, cut-proof, and bullet-proof tool 1 can be obtained.

[0054] In addition, by the storage space temporary fixing step, the base 11 and the storage space forming body 12 can be integrated, and the storage operation of each plate 13 into each storage space in the subsequent plate storage step can be performed easily and efficiently. Further, by the storage space forming body fixing step, the storage space forming body 12 can be completely fixed to the base 11 in a state where each plate 13 is stored in each storage space. By adopting a configuration including these steps, a manufacturing method of the first protector 10 with good manufacturing efficiency and a manufacturing method of the blade-proof, stab-proof, and bullet-proof tool 1 can be obtained.

[0055] In the above-described embodiment of the present invention, the storage space forming body 12 having a plurality of storage spaces in the horizontal direction is used, and a plurality of storage space forming bodies 12 are stacked in the vertical direction. However, the present invention is not necessarily limited to such a configuration. Instead, a storage space forming body 12 having a plurality of storage spaces in the vertical direction may be used, and a plurality of storage space forming bodies 12 may be stacked in the horizontal direction. Such a configuration is also included in the scope of the present invention.
