Description

[Technical Field]

[0001] The present disclosure relates to body protective equipment, body protective structures of clothing, and body protective clothing that have a protective function to protect the wearer from external attacks and harm, such as a bulletproof vest or stab-proof vest, and a temperature regulating function to regulate the wearer's body temperature. [Background technology]

[0002] In recent years, there have been many days of extreme heat throughout the year, and as a measure to prevent heatstroke caused by extreme heat, people are encouraged to drink fluids frequently and use air conditioners in moderation. On the other hand, there are many people who work in jobs that require them to wear protective clothing with heavy safety equipment, such as bulletproof vests and stab-proof vests, in order to perform their current duties.

[0003] There are cases where protective clothing wearers have to perform their duties for long periods of time in hot and humid environments or in scorching heat that creates a heat island effect. In such cases, it is difficult for protective clothing wearers to avoid the heat while performing their duties at the site.

[0004] Therefore, Patent Document 1 discloses an example of body temperature regulating clothing that not only regulates the user's body temperature but also adds a protective function to protect the user from external attacks and harm.

[0005] Patent Document 1 describes an air-cooled suit in which a planar heat transfer body is placed between an outer material and an inner material, a protective member is provided on the outer surface of the planar heat transfer body, and the heat absorbed by the inner surface of the planar heat transfer body is dissipated to the outside by air blown from a fan. According to Patent Document 1, the air-cooled suit not only improves the cooling effect on the wearer, but also improves bulletproof and stab-proof functions against external hazards by the protective member. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-097106 Summary of the Invention [Problem to be solved by the invention]

[0007] However, in Patent Document 1, heat from the body is conducted to a planar heat transfer element, and the heat conducted to the planar heat transfer element is dissipated to the outside by a fan device. Therefore, unless the planar heat transfer element is in close contact with the wearer's body via the inner material, the heat from the body is not sufficiently conducted to the planar heat transfer element, and the body heat cannot be dissipated efficiently. Furthermore, for example, on an extremely hot day when the outside temperature exceeds 35°C, if the wearer's body is wet with sweat and in close contact with the inner material layered on the planar heat transfer element, the wearer will feel extremely uncomfortable.

[0008] In addition, when a wearer of air-cooled clothing performs duties at a site exposed to the scorching sun on a particularly hot day, such as when the outside temperature exceeds 35°C, the wearer cannot quickly cool their body by directly contacting the cool air or cold air that is significantly different from the outside temperature. Therefore, on extremely hot days, the technology of Patent Document 1 cannot be an effective measure to prevent heatstroke for workers who work in jobs that require the wearing of protective clothing.

[0009] In particular, given the current situation, when workers are performing their duties wearing protective clothing equipped with heavy safety equipment, many users of protective clothing are seeking effective heatstroke prevention measures that will ensure their bodies are comfortable even on extremely hot days.

[0010] The present disclosure has been made to solve the above-mentioned problems, and aims to provide body protective equipment, a body protective structure for clothing, and body protective clothing that, when worn by a user, can protect the user from external attacks and harm, like a bulletproof vest or stab-proof vest, and that can regulate the user's body temperature to an appropriate level when worn, even if the environment surrounding the user is hot, thereby improving comfort. [Means for solving the problem]

[0011] (1) A body protective equipment according to one aspect of the present disclosure, which has been made to solve the above problems, includes a main body formed by overlapping an inner fabric having an air outlet formed therein and an outer fabric so as to be able to cover a protective area of ​​a user's body including at least the back, a protective part configured to have at least one of a bulletproof function and a stab-proof function, a blower fan unit for blowing air, an air circulation part having an air circulation path formed therein, and a control means for electrically controlling the main body, and the protective part is disposed between the inner fabric and the outer fabric so as to face the outer fabric. the air circulation section is arranged between the inner fabric and the outer fabric on the opposite side of the protective section, the air blower fan unit is detachably attached to a fan attachment section of the main body that avoids the position where the protective section is arranged, and the air blower fan unit allows the air that has flowed in between the inner fabric and the protective section to flow out of the inner fabric through the air circulation section and the air outlet; and the clothing worn by the user and the main body can be detachably attached at a position corresponding to the protective area.

[0012] According to this aspect, even when a user wearing the body protective equipment performs work, etc., in an environment exposed to the scorching sun, such as on a work site on an extremely hot day when the outside temperature exceeds 35°C, the blower fan unit can blow air to the user's protected area. This allows the user to be freed from discomfort caused by the heat and to perform work, etc., activities comfortably. Therefore, the body protective equipment can be one of the measures to prevent heatstroke caused by extreme heat for the user.

[0013] In addition, in the body protective equipment which is one aspect of the present disclosure and the body protective structure of clothing which is another aspect of the present disclosure described below, the concept of clothing is broadly divided into (a) outerwear such as jackets, jumpers, suits, vests, etc., (b) underwear such as pants, trousers, etc., and (c) socks worn on the feet or legs such as socks, foot warmers, etc., and this is a general term that includes each of the concepts (a), (b), and (c).

[0014] However, outerwear, which is one of the objects of clothing, is essential for the body protective equipment of one embodiment of the present disclosure and the body protective structure of clothing of another embodiment of the present disclosure.

[0015] (2) In the aspect described in (1) above, when the user's back is covered by the main body, the direction corresponding to the neck side relative to the length of the user is defined as the upper side of the main body and the direction corresponding to the waist side is defined as the lower side of the main body. It is preferable that the fan mounting part has a plate-shaped member and is arranged between the lower end of the inner fabric, which is located on the lower side, and the lower end of the outer fabric, and that the fan mounting part can be reversibly folded down within a rotation range toward the outside of the outer fabric relative to the inner fabric at the connection part with the lower end of the inner fabric.

[0016] According to this aspect, when a user wearing the body protection equipment assumes a seated position, the fan mounting section can be rotated and folded at the connection point, preventing the user from being crushed by the air blower fan unit as the user assumes a seated position and preventing damage to the air blower fan unit.

[0017] (3) In the aspect described in (1) or (2) above, it is preferable that the air circulation section is made of double Russell fabric having countless voids geometrically arranged in a three-dimensional structure by Russell knitting of fibers.

[0018] According to this aspect, when the ventilation section has a ventilation member made of double Russell fabric, the air supplied by the blower fan unit can pass through the air circulation section smoothly with minimal pressure loss when passing through the air circulation section.

[0019] (4) In the aspect described in any one of (1) to (3) above, it is preferable that the device is provided with a Peltier element unit having a Peltier element, heat dissipation fins formed on one side of the Peltier element and the other side opposite the one side, and a heat dissipation fan for blowing air to the heat dissipation fins, and that the Peltier element unit is detachably attached to the inner fabric in an element mounting portion formed on the inner fabric such that the other side is positioned between the inner fabric and the protective portion and the one side is positioned outside the inner fabric by inserting it through a through hole formed in the element mounting portion.

[0020] According to this aspect, the user can efficiently cool his / her back or other parts that are wet with sweat due to excessive sweating by transferring cold heat from the Peltier element unit.

[0021] (5) In any one of the aspects (1) to (4) above, it is preferable that the air circulation section is arranged in an internal space of the main body section formed by communication between the blowing side area of ​​the blower fan unit and the intake side area of ​​the heat dissipation fan.

[0022] According to this aspect, the exhaust air that has exchanged heat with the heat dissipation fins can flow out of the inner fabric through the air outlet of the inner fabric together with the air supplied by the blower fan unit through the ventilation section. At this time, the exhaust air is mixed with the air supplied by the blower fan unit and is temperature-adjusted before flowing out of the air outlet. Therefore, even if the exhaust air mixed with the air comes into contact with the user when it flows out, the exhaust heat has almost no effect on the user's body.

[0023] (6) In any one of the modes (1) to (5) above, it is preferable that the air outlet is arranged at the upper end of the inner fabric covering the upper part of the shoulder blades within the protective area.

[0024] According to this aspect, by supplying air from the air outlet to the upper shoulder blades of the user, which are particularly sensitive to heat, for example, near the user's cervical vertebrae and are prone to becoming humid due to sweat, the discomfort felt by the user can be relieved, allowing the user to be active in comfort.

[0025] (7) In any one of the modes (1) to (6) above, it is preferable that a portion of the inner fabric is made of mesh fabric, and the air outlet is an opening within the mesh of the mesh fabric.

[0026] According to this aspect, the mesh fabric has air outlets widely distributed across the entire fabric, so that the air flowing out from the air outlets reaches a wider area of ​​the user's protected area.

[0027] (8) In the aspect described in any one of (1) to (7) above, it is preferable that the main body portion is provided with a fastening means for fastening it to the clothing to be worn.

[0028] According to this aspect, for example, body armor can be attached to a wider variety of clothing, even clothing that does not originally have bulletproof or stab-proof functions.

[0029] (9) In order to solve the above problems, a body protection structure for clothing according to another aspect of the present disclosure is provided, in clothing worn by a user, with a main body formed by overlapping an inner fabric having an air outlet and an outer fabric so as to be able to cover a protective area of ​​the user's body including at least the back, a protective part configured to have at least one of bulletproof and stab-proof functions, a ventilation fan unit for blowing air, an air circulation part having an air circulation path, and a control means for electrically controlling the main body. The protective part is arranged between the inner fabric and the outer fabric, facing the outer fabric, and the air circulation part is arranged between the inner fabric and the outer fabric on the opposite side of the outer fabric sandwiching the protective part; the air blower fan unit is detachably attached to a fan mounting part of the main body that avoids the position where the protective part is arranged, and the air blower fan unit allows the air that flows in between the inner fabric and the protective part to flow out of the inner fabric through the air circulation part and the air outlet.

[0030] (10) Furthermore, in another aspect of the present disclosure, body protective clothing, which has been made to solve the above problems, is characterized in that a body protective part having a protective member that performs at least one of the following functions: a bulletproof function that can protect the body from flying bullets from the outside, or a blade-proof function that can protect the body from external harm caused by a blade, is provided on the body protective clothing, and the body protective part is configured with the body protective structure of the clothing described above in (9).

[0031] According to this embodiment, even when a user performs work, etc., in a work site exposed to the scorching sun on a scorching hot day when the outside temperature exceeds 35°C, the blower fan unit can blow air to the user's protected area. This allows the user to be freed from discomfort caused by the heat and to perform work, etc., activities comfortably. Therefore, personal protective equipment can be one of the measures to prevent heatstroke caused by extreme heat for the user. [Effects of the Invention]

[0032] Therefore, the body protective equipment, body protective structure of clothing, and body protective clothing disclosed herein have the excellent effect of allowing a user to protect themselves from external attacks and harm, like a bulletproof vest or stab-proof vest, by wearing them, and also allowing the user's body to adjust to an appropriate temperature when worn, even if the environment surrounding the user is hot, thereby improving comfort.

DETAILED DESCRIPTION OF THE INVENTION

[0034] Hereinafter, the body protective equipment, the body protective structure of clothing, and the body protective clothing according to the present disclosure will be described in detail with reference to embodiments.

[0035] The body protective equipment according to the present disclosure is protective equipment attached to clothing worn by a user. The body protective structure of the clothing according to the present disclosure relates to a technology that adds a protective function for the wearer and a temperature regulating function for the wearer to the clothing by applying the key technology of the body protective equipment according to the present disclosure. Furthermore, the body protective clothing according to the present disclosure is, for example, like a bulletproof vest or a stab-proof vest, in which a body protective part having a body protective function is added to the main body of the clothing, and this body protective part is configured with the body protective structure of the clothing according to the present disclosure.

[0036] The following mainly describes in detail the body protective equipment according to the embodiment, and briefly describes the body protective structure of the clothing according to the embodiment and the body protective clothing according to the embodiment.

[0037] The body protective equipment of the embodiment is attached to the clothing of people who are required to wear protective equipment with heavy safety equipment as part of their job, such as police officers, riot police officers, security guards, and security officers who perform security duties at public facilities such as ports, airports, and stations, and who are engaged in the performance of their current duties.

[0038] The clothing to be fitted includes uniforms, work clothes, etc. Specifically, when the clothing is an outer garment worn on the outside of the body, such as a jacket, blouson, or in some cases a vest, the body protective equipment according to the embodiments is attached to, for example, the lining of the outer garment or the outer surface of the inner garment. When the clothing is an inner garment such as a shirt or vest, which is worn on the inside of the body rather than an outer garment such as a jacket, the body protective equipment according to the embodiments is attached to, for example, the outer surface of the inner garment or the lining of the outer garment.

[0039] Alternatively, the body protection equipment according to the embodiment may be worn in a state where it is fixed to the upper body of the wearer by being hung from the shoulder or by a belt wrapped around the torso.

[0040] <Overview of Body Protective Equipment 1> First, a brief overview of a body protective equipment 1 according to this embodiment will be described with reference to FIGS. 1 to 5. FIG.

[0041] Fig. 1 is a perspective view showing a body protective equipment according to an embodiment, and Fig. 2 is a perspective view of the body protective equipment shown in Fig. 1 viewed from below. Fig. 3 is a front view of the body protective equipment shown in Fig. 1, and Fig. 4 is a rear view of the body protective equipment. Fig. 5 is an explanatory view showing a view seen in the direction of arrow AA in Fig. 1, partially in cross section.

[0042] In the body protective equipment shown in Fig. 1, the direction from upper left to lower right is defined as the width direction W, the direction from lower left to upper right is defined as the depth direction D, and the up-down direction is defined as the height direction H, and the directions defined in Fig. 1 are also used in Fig. 2 and subsequent figures. Furthermore, the electrical wiring of the blower fan unit and Peltier element unit, power supplies, etc. are not shown in the figures.

[0043] 1 to 5, the body protective equipment 1 includes a main body 2, a protective part 3, a blower fan unit 5 that blows air, an air circulation part 4 in which an air circulation path FP is formed, and a control part 7. The control part 7 corresponds to the control means according to the present disclosure.

[0044] <About main body 2> 26 is a schematic diagram illustrating the movement of the fan mounting portion of the body protective equipment according to the embodiment, showing the state in which the fan mounting portion is folded due to the user's seated posture. As shown in FIGS. 1 to 5, the main body 2 has an inner fabric 10 and an outer fabric 20. In the main body 2, the inner fabric 10 and the outer fabric 20 are overlapped with each other, and the outer edges of the inner fabric 10 and the outer edges of the outer fabric 20 are fixed to each other.

[0045] The main body 2 is formed in a shape capable of covering a protection region BP of the body of the wearer HM, including at least the back BK, as shown in Fig. 26. Specifically, the main body 2 is in the form of a vest similar to the contour shape of the back of a vest, and is formed of an upper back 2A capable of covering mainly the areas of the scapular regions, upper scapular regions, and spine, and a lower back 2B capable of covering the areas of the spine, lower scapular regions, lumbar region, and abdominal region, as shown in Figs.

[0046] An air outlet 14 is formed in the inner fabric 10. The air outlet 14 is open and communicates between the inside and outside of the main body 2. In this embodiment, the inner fabric 10 is made up of a windproof fabric part 11 and a mesh fabric part 12.

[0047] The windproof fabric portion 11 of the inner fabric 10 and the outer fabric 20 are both windproof fabrics, and are made of synthetic resin fibers such as nylon and polyester, which have excellent heat resistance, strength resistance, and transpiration properties.

[0048] The mesh fabric portion 12 is formed of a mesh fabric having a mesh structure made of synthetic resin fibers that have excellent heat resistance, strength resistance, and transpiration properties, such as nylon, polyester, etc. The air outlet 14 is an opening in the mesh of the mesh fabric used in the mesh fabric portion 12.

[0049] 1, 3, and 5, in the body protective equipment 1, the mesh fabric portion 12 of the inner fabric 10 is provided over the entire upper back 2A side and over the lower back 2B portion that mainly covers the spine, lower scapular region, and lumbar region. The windproof fabric portion 11 is provided over the ventral side of the lower back 2B and other portions. That is, an air outlet 14 is also provided at the upper end of the inner fabric 10 of the upper back 2A that covers the upper scapular region BK1 within the protection region BP of the body of the wearer HM.

[0050] The air outlets provided in the inner fabric 10 are not limited to the air outlets 14 provided within the mesh of the mesh fabric used in the mesh fabric portion 12, but may be formed as air outlets 14X perforated to a predetermined size in the windproof fabric portion 11, as shown in Fig. 8. Fig. 8 is an explanatory diagram showing the body protective equipment shown in Fig. 1 configured with an inner fabric having air outlets according to a modified example.

[0051] As shown in FIGS. 1 to 5 , in the body protective equipment 1, a blower fan unit 5 (described later) is detachably attached to a fan attachment section 21 of the main body 2, which is positioned away from the position of the protective section 3. Specifically, the main body 2 has gussets 23 on both sides in the width direction W, which are interposed between the inner fabric 10 and the outer fabric 20, and has the fan attachment section 21 on the lower side in the height direction H. The fan attachment section 21 has a plate-shaped core material 22. The fan attachment section 21 is disposed in the main body 2 between the lower end of the inner fabric 10, which is positioned on the lower side in the height direction H, and the lower end of the outer fabric 20, and is disposed in a manner that connects the inner fabric 10 and the outer fabric 20 together with a windproof connecting fabric, similar to the windproof fabric section 11.

[0052] As shown in Figures 2, 4, and 5, in the fan mounting section 21, two blower fan units 5 are mounted on a core material 22 in this embodiment. The core material 22 is a plate material made of resin, such as foamed polyethylene, and is several millimeters thick. The fan mounting section 21 is formed by overlapping the core material 22 arranged inside the main body 2 with the connecting fabric. This provides the fan mounting section 21 with a degree of rigidity that prevents it from losing its shape.

[0053] 6 is a schematic diagram illustrating the range of motion of the fan mounting part of the body protective equipment according to the embodiment. As shown in Fig. 6, the fan mounting part 21 can be reversibly tilted at the connection part 24 with the lower end of the inner fabric 10 within a rotation range toward the outside of the outer fabric 20 relative to the inner fabric 10.

[0054] A more detailed explanation follows. In this embodiment, the fan mounting section 21 is normally held in a natural state in a position where the outer fabric 20 side is tilted at a higher angle θ1 than the inner fabric 10 side, with respect to a horizontal line along the depth direction D, as shown in Fig. 6, due to the weight of the two blower fan units 5, etc. The fan mounting section 21 is folded at an angle θ2 (θ1<θ2) with respect to the horizontal line, at which the blower fan unit 5 comes into contact with the inner fabric 10. The range of motion of the foldable fan mounting section 21 is angle θ3 (θ3<θ2), as shown in Fig. 7.

[0055] As an example, the angle θ1 is approximately 10≦θ1≦60°, and the angle θ2 is approximately 10<θ2<70°.

[0056] Note that due to the weight of the blower fan unit 5 and the like, the orientation of the fan mounting part 21 may normally be maintained in a horizontal orientation along the depth direction D, as illustrated in FIG. 7, as a natural state. In this case, the angle θ2 is approximately 0≦θ2<70°. Note that FIG. 7 is a schematic diagram illustrating the range of motion of a fan mounting part according to a modified example of the body protective equipment according to the embodiment. Furthermore, when the fan mounting part 21 is in a natural orientation, the angle of the fan mounting part 21 is not limited to 10≦θ1≦60° and can be changed in various ways.

[0057] <About protective part 3> Next, the protective part 3 will be described with reference to Figs. 5 and 9. As shown in Fig. 5, the protective part 3 is disposed inside the main body 2 so as to face the outer fabric 20. The protective part 3 has at least one of bulletproof and stab-proof functions and is a type of plate-shaped protective gear made from materials according to well-known technology. The protective functions of protective gear made from materials according to well-known technology are broadly divided into three types: first protective gear specifications, second protective gear specifications, and third protective gear specifications.

[0058] The first protective gear specification is protective gear configured to have both bulletproof and stab-resistant functions. The second protective gear specification is protective gear configured with bulletproof functions. The third protective gear specification is protective gear configured with stab-resistant functions.

[0059] In the body protective equipment, body protective structure of clothing, and body protective clothing disclosed herein, the protective part is a protective equipment configured to be used in any of the cases of the first protective equipment specification, the second protective equipment specification, and the third protective equipment specification.

[0060] In this embodiment, for convenience of explanation, a protective part having a protective function according to the first protective equipment specification will be described. Fig. 9 is a plan view showing a protective part configured in a body protective equipment according to the embodiment. In the protective part 3 shown in Fig. 9, the left-right direction is defined as a width direction W1, the direction perpendicular to the paper surface is defined as a depth direction D1, and the up-down direction is defined as a height direction H1.

[0061] As shown in Fig. 9, the protective part 3 is a pad-like protective gear formed by storing protective members 41, which have bulletproof and blade-proof functions, in a densely integrated plate-like form inside a storage member 42 formed in a bag shape from a resin sheet material, and sealing the storage member 42. As shown in Figs. 4, 5, and 26, the protective part 3 is formed in a form that can cover the protection area BP within the upper body of the user HM.

[0062] Specifically, when the protection area BP is the entire back BK of the user HM as well as the area of ​​the sides of the upper body between the armpits and flanks, the protective member 41 is formed, for example, in a substantially inverted T-shape with a thickness of about 10 to 10 mm, with a substantially rectangular first portion that contacts the entire back BK and a substantially rectangular second portion that contacts the areas of the sides of the upper body added to both the left and right sides of the first portion, as shown in Fig. 9. In the protective unit 3, the protective member 41 is housed inside a housing member 42 that is molded to fit the shape of the protective member 41.

[0063] The shape of the integrated protection member 41 is not limited to the illustrated shape, but can be modified in various ways.

[0064] Common materials used for the protective member 41 include metals such as stainless steel, titanium, duralumin, magnesium, and magnesium alloys. Examples of high-strength fibers include synthetic fibers made from aromatic polyamide, such as Kevlar (registered trademark). Other examples include fibers made from ultra-high molecular weight polyethylene (UHMWPE), such as Dyneema (registered trademark). Other examples include ceramics.

[0065] The blade-protecting member may be, for example, a composite material made by sewing together Kevlar fiber (registered trademark) or a metal plate and polycarbonate.

[0066] <About Ventilation Section 4> Next, the air circulation section 4 will be described with reference to Figs. 10 to 12. Fig. 10 is a schematic diagram showing, in plan view, the structure of the double raschel fabric that constitutes the air circulation section according to the embodiment. Fig. 11 is a schematic diagram showing, on an enlarged scale, the structure of the double raschel fabric that constitutes the air circulation section according to the embodiment. Fig. 12 is a schematic diagram of the structure of the double raschel fabric shown in Fig. 10, as seen from the direction of arrow BB in Fig. 11. In the double raschel fabric (ventilation member 51) shown in Fig. 10, the left-right direction is defined as the width direction W2, the direction perpendicular to the paper surface is defined as the thickness direction D2, and the up-down direction is defined as the height direction H2.

[0067] As shown in Fig. 10, the air circulation section 4 has a shape corresponding to the shape and arrangement position of the protective section 3, and is arranged between the inner fabric 10 on the opposite side of the outer fabric 20 sandwiching the protective section 3, as shown in Fig. 4 and Fig. 5. Specifically, the air circulation section 4 is arranged in the internal space 2S of the main body 2 formed by communication between the air-outlet side area Q1 of the blower fan unit 5 and the air-inlet side area Q2 of the heat dissipation fan 98 (see Fig. 5).

[0068] The air circulation section 4 is made of a ventilation member 51, which in this embodiment is made of a double raschel fabric that has a regular three-dimensional structure and numerous geometrically arranged voids, as shown in Figures 11 and 12, produced by raschel knitting of fibers. Specifically, in this embodiment, the double raschel fabric is made of synthetic fibers such as polyester or nylon.

[0069] 11 and 12, the double raschel fabric (ventilation member 51) has countless regular hexagonal voids 55 present in all directions, and adjacent voids 55 communicate with each other through gaps between the vertical stitches 54. As a result, the double raschel fabric is relatively lightweight and has extremely high breathability. Therefore, in the ventilation section 4, when air AR is sent by the blower fan unit 5 toward the double raschel fabric in the direction of arrow B in FIG. 5, the air AR can pass smoothly through the countless voids 55 present in all directions, forming a circulation path FP for the air AR.

[0070] The double raschel fabric (ventilation member 51) is raschel knitted in which stitches 54 are connected in the vertical direction (height direction H2), and by knitting the outer fabric 52 and lining fabric 53 simultaneously, it is a fabric that is resistant to deformation and exhibits elasticity with greater recovery force. The double raschel fabric has a shape that bulges in the thickness direction D2 as the outer fabric 52 and lining fabric 53 move away from each other. The double raschel fabric maintains a constant thickness, for example, with a distance of around 10 mm to several tens of mm between the outer fabric 52 and lining fabric 53 (the distance in the thickness direction D2 in Figure 12).

[0071] Additionally, in this embodiment, the double raschel fabric used in the ventilation section 4 has characteristics that satisfy the following condition in terms of the relationship between thickness and strength. That is, in a test in which the protective section 3 is placed on the outer surface 52 of the double raschel fabric under the condition that the double raschel fabric is placed on a table with a horizontal surface, with the lining 53 abutting on this horizontal surface, the double raschel fabric is elastically deformed and compressed by the weight of the protective section 3.

[0072] At this time, even if the double russell fabric is subjected to a load from the protective part 3, it is important that the double russell fabric in a compressed state is guaranteed to have a thickness of at least several mm, and that uncrushed voids 55 remain throughout the entire fabric.

[0073] If the ventilation section 4 is made of double raschel fabric with properties that satisfy these conditions, the ventilation section 4 will not be completely crushed by the load applied by the protective section 3 due to the movements of the user HM while the user HM is active while wearing the body protective equipment 1, body protective clothing 100, etc. according to this embodiment. Therefore, it is possible to prevent the air AR sent from the blower fan unit 5 from being unable to circulate through the ventilation section 4.

[0074] In the embodiment, a double raschel fabric is used for the ventilation member 51 forming the air circulation section 4, but the ventilation member 51 is not limited to a double raschel fabric and can be, for example, a hollow member having a honeycomb structure inside, or a member having a structure according to modified examples 1 and 2 as described below, and various other modifications are possible.

[0075] (Structure of ventilation member according to modified example 1) Fig. 13 is an explanatory diagram showing a ventilation member used in an air circulation section according to the embodiment configured with a structure according to Modification 1. As shown in Fig. 13, ventilation member 51X according to Modification 1 is a member made of resin or the like formed by intermittently providing a plurality of protrusions 57X upright on a flat plate portion 56X, and gaps 55X between adjacent protrusions 57X form air circulation paths FP.

[0076] (Structure of ventilation member according to modified example 2) Fig. 14 is an explanatory diagram showing a ventilation member used in an air circulation section according to an embodiment configured with a structure according to Modification 2. As shown in Fig. 14, ventilation member 51Y according to Modification 2 is a member made of resin or the like having corrugated plate portion 56Y formed by periodically oscillating up and down like a sine wave. In corrugated plate portion 56Y, gaps 55Y between adjacent semicircular curved portions form air circulation paths FP.

[0077] <About Blower Fan Unit 5> Next, the blower fan unit will be described with reference to Figs. 15 to 18. Fig. 15 is a perspective view of an example of a blower fan unit attached to body protective equipment according to an embodiment, viewed from the air blowing side, and Fig. 16 is an exploded perspective view of the blower fan unit shown in Fig. 15. Fig. 17 is a cross-sectional view taken along arrow CC in Fig. 15, showing a portion of the blower fan unit shown in Fig. 15 as seen from the side. Fig. 18 is an explanatory diagram showing a blower fan unit according to a modified example attached to body protective equipment according to an embodiment.

[0078] In the blower fan unit 5 according to this embodiment, the upper left-to-lower right direction in FIG. 15 is defined as the axial direction AX1, and in FIG. 17, the direction perpendicular to the axial direction AX1 is defined as the radial direction RD1, and the circumferential direction centered on the axis L1 along the axial direction AX1 is defined as the circumferential direction CR1.

[0079] 15 to 17, the blower fan unit 5 is an axial flow fan (propeller fan) configured so that a plurality of blades 77 can be rotated about an axis L1 by a drive unit (not shown) equipped with an electric motor or the like. The blower fan unit 5 is broadly divided into a case main body 60 and the blades 77.

[0080] The case body 60 is made up of an intake side case portion 61 and a blower side case portion 71. The intake side case portion 61 has an intake side flange 62, an intake side peripheral wall portion 63, an intake portion 65, etc. The intake side flange 62 is formed in an annular shape, and the inside of this intake side flange 62 forms the intake portion 65. The intake portion 65 has an intake port 66 that takes in air AR into the case body 60.

[0081] A plurality of airflow direction adjustment members 75 are formed in the blower-side case 71. As an example, the airflow direction adjustment member 75 is composed of a laminar flow introduction section 75A and an airflow direction changer 75B. The laminar flow introduction section 75A is a plate-shaped section arranged parallel to the axis of the blade 77, i.e., along the axial direction AX1. The airflow direction changer 75B is a plate-shaped section bent outward in the radial direction RD1 centered on the axis L1. The laminar flow introduction section 75A and the airflow direction changer 75B are connected and integrated.

[0082] The airflow direction adjustment members 75 are arranged concentrically about the axis L1 and intermittently overlap with gaps 76 sandwiched between them in the radial direction RD1. As shown in Fig. 17, in each of the airflow direction adjustment members 75, the bending angle, which is the angle of the airflow direction varying portion 75B relative to the laminar flow introduction portion 75A, increases sequentially from the inside in the radial direction RD1 to the outside in the radial direction RD1 for each airflow direction adjustment member 75. As a result, in all of the airflow direction adjustment members 75, the airflow direction varying portion 75B spreads outward in the radial direction RD1.

[0083] The wind direction adjustment member is not limited to the wind direction adjustment member 75 having a structure with a wind direction variable section 75B bent at a bending angle as illustrated, but may be formed of a wind direction adjustment member 75X having a straight shape along the axial direction AX1 as shown in FIG. 18.

[0084] In the case main body 60 shown as an example, the intake-side peripheral wall portion 63 of the intake-side case portion 61 is inserted into the case internal space of the blower-side case portion 71. Thereafter, the intake-side case portion 61 and the blower-side case portion 71 rotate relatively about the axis L1, and the protrusion 64 of the intake-side case portion 61 and the fixed guide 74 of the blower-side case portion 71 are engaged and positioned. In this way, the intake-side case portion 61 and the blower-side case portion 71 are assembled to match the thickness of the core material 22 to be sandwiched by adjusting the distance between them.

[0085] The engagement between the protrusion 64 and the fixed guide 74 is the same as in the Peltier element unit 6, and therefore the engagement structure between the protrusion 64 and the fixed guide 74 will be described in detail later in connection with the Peltier element unit 6.

[0086] Furthermore, the assembly structure between the intake side case portion 61 and the blower side case portion 71 is not limited to the engagement structure between the protrusion piece 64 and the fixed guide 74 as illustrated, but may be any structure that allows the blower fan unit to be attached to the core material 22.

[0087] <About Peltier element unit 6> Next, the Peltier element unit 6 will be described with reference to Fig. 1 and Figs. 19 to 24. Fig. 19 is a front view showing an example of a Peltier element unit attached to a body protective equipment according to an embodiment. Fig. 20 is a side view of the Peltier element unit shown in Fig. 19 as seen from the heat transfer surface side, and Fig. 21 shows a side view as seen from the exhaust section side. Fig. 22 is an exploded perspective view of the Peltier element unit shown in Fig. 19.

[0088] In the air-blowing Peltier element unit 6 according to this embodiment, in FIG. 19, the vertical direction is defined as the axial direction AX2, the direction perpendicular to the axial direction AX2 is defined as the radial direction RD2, and the circumferential direction centered on the axis L2 along the axial direction AX2 is defined as the circumferential direction CR2.

[0089] A more detailed description will be given below. As shown in Fig. 22, the Peltier element unit 6 is made up of a Peltier element 93, a heat sink 94, a heat dissipation fan 98, a housing main body 80A, a lid portion 80B, a fixture 89, etc. The heat sink 94 corresponds to the heat dissipation fin according to the present disclosure. The Peltier element 93, the heat sink 94, and the heat dissipation fan 98 are housed inside the housing 80, which is made up of the housing main body 80A and the lid portion 80B.

[0090] (Peltier element 93) 22, the Peltier element 93 is a type of plate-shaped semiconductor thermoelectric element having one surface 93a and an opposite surface 93b. The Peltier element 93 is electrically connected to the control unit 7 (see FIG. 1) and a power source (not shown).

[0091] When a direct current is supplied from a power source to the Peltier element 93, one surface 93a absorbs heat and enters an endothermic state (cooling surface) due to the Peltier effect, while the other surface 93b generates heat and enters a heat-generating state (heating surface). When the direction of the supplied direct current is reversed by the control unit 7, in the Peltier element 93, the other surface 93b absorbs heat and enters an endothermic state (cooling surface), while the one surface 93a generates heat and enters a heat-generating state (heating surface).

[0092] That is, when the control unit 7 reverses the direction of the direct current supplied to the Peltier element 93, the cooling surface and the heating surface are switched between the one surface 93a and the other surface 93b.

[0093] Peltier element 93 has the property of simultaneously absorbing and generating heat at temperatures that are relatively different from the outside air temperature, for example, in a temperature range of about 20 to 50°C. That is, for example, when Peltier element 93 absorbs and generates heat in the summer when the outside air temperature is 35°C, the cooling surface generates heat of 15 to -15°C, which becomes cold heat that cools the body. At the same time, the heating surface generates heat of 55 to 85°C, which becomes exhaust heat.

[0094] In this embodiment, one surface 93a of the Peltier element 93 is the cooling surface, and is attached in close contact with the body side of the user HM wearing the body protective equipment 1 via a heat transfer plate 92 that transfers cold and heat, and a grease layer similar to the grease layer 97 described below. The control unit 7 can control the temperature of the heat absorbed by the one surface 93a as cold in multiple stages. The heat absorption temperature of the Peltier elements 93 for the two Peltier element units 6 attached to the body protective equipment 1 can be varied by the control unit 7.

[0095] Specifically, the control unit 7 controls the heat absorption in the Peltier element 93 by, for example, controlling the current when electricity is passed through the Peltier element 93, controlling the voltage applied to the Peltier element 93, controlling the duty, etc., thereby adjusting and varying the temperature of the cold heat transferred to the heat transfer plate 92.

[0096] On the other hand, when the Peltier element 93 absorbs and generates heat in winter when the outside temperature is 5°C, the cooling surface exhibits heat of -15 to -45°C, which becomes exhaust heat. At the same time, the heating surface exhibits heat of 25 to 55°C, which becomes warmth for warming the body.

[0097] In this embodiment, the Peltier element 93 has temperature characteristics of absorbing heat and generating heat at the same time in a temperature range of about 20 to 50° C. relative to the outside air temperature.

[0098] However, the temperature characteristics of the Peltier element 93 are not limited to those described in this embodiment, and may be modified as appropriate as long as the temperature characteristics are such that the heat from one surface 93a of the Peltier element 93 can cool the body to a degree that does not cause frostbite and warm the body to a degree that does not cause burns. As an example, the temperature characteristics of the Peltier element 93 are a temperature range of about 10 to 40°C or about 10 to 20°C relative to the outside air temperature.

[0099] (heat sink 94) Fig. 24 is a half cross-sectional view showing the Peltier element unit shown in Fig. 19 attached to the element mounting portion of the inner fabric. As shown in Figs. 22 and 24, the heat sink 94 is formed by vertically erecting countless fins 96 formed over almost the entire area of ​​the other surface 93b of the Peltier element 93 from a flat plate portion 95 with gaps between adjacent fins 96.

[0100] As shown in FIG. 24, in the Peltier element unit 6, a surface 95a of a flat plate portion 95 of a heat sink 94 and a second surface 93b of a Peltier element 93 are disposed opposite each other so as to be in surface contact with each other.

[0101] However, strictly speaking, due to a difference in accuracy between the surface shape of the surface 95a of the flat plate portion 95 of the heat sink 94 and the surface shape of the other surface 93b of the Peltier element 93, there is a small gap (air gap) between the surface 95a and the other surface 93b of the flat plate portion 95. Therefore, a grease layer 97, which fills this air gap with grease, is interposed between the Peltier element 93 and the heat sink 94. The grease has relatively high thermal conductivity, for example, a thermal conductivity of at least 5 W / m·K, and maintains a relatively high viscosity within a temperature range of approximately 0 to 100°C.

[0102] In the Peltier element unit 6, the grease layer 97 is provided so that the heat generated in the Peltier element 93 is transferred to the heat sink 94 on the one surface 93a and the other surface 93b while reducing heat transfer loss.

[0103] 1, in this embodiment, two Peltier element units 6 are attached to the body protective equipment 1. Specifically, the Peltier element unit 6 is detachably attached to the inner fabric 10 in a state where the other surface 93b side is arranged between the inner fabric 10 and the protective part 3 in the element attachment part 15 formed on the inner fabric 10, and the one surface 93a side is inserted through a through-hole 15H formed in the element attachment part 15 and arranged outside the inner fabric 10.

[0104] In this embodiment, the body protective equipment 1 is configured to have two Peltier element units 6 attached thereto. However, the number of Peltier element units 6 attached to the body protective equipment 1 is not limited to two, and can be variously changed, for example, to one, three or more, etc.

[0105] (heat dissipation fan 98) 22, the heat dissipation fan 98 is a blower unit that sends air AR to the heat sink 94. The heat dissipation fan 98 is a fan that, by rotating blades 99, draws in outside air AR through an intake port of an intake section 88A in the housing main body 80A, introduces it from the adjacent heat sink 94 side, and sends the air toward an exhaust port of an exhaust section 88B in the lid section 80B. In this embodiment, the heat dissipation fan 98 is a multi-blade blower (sirocco fan), which is a type of centrifugal blower.

[0106] A sirocco fan is a roughly cylindrical blower with multiple blades arranged in a ring shape around a central axis of rotation, and blows air drawn in along the central axis outward from between the rotating blades.

[0107] In the Peltier element unit 6, one surface 93a of the Peltier element 93 is a cooling surface that provides cold heat to cool the body, and the heat sink 94, which has become hot due to the heat exhausted from the other surface 93b of the Peltier element 93, is air-cooled by exchanging heat with the air AR drawn in by the heat dissipation fan 98.

[0108] The exhaust air HL (see FIGS. 27 and 28), which is air heated by heat exchange with the heat sink 94, is at a temperature that is significantly lower than the heat generation temperature on the other surface 93b of the Peltier element 93 and is closer to the temperature of the intake air. Therefore, the exhaust air HL after heat exchange is discharged outside the Peltier element unit 6 through the exhaust port of the exhaust section 88B by the heat dissipation fan 98, as shown in FIGS. 21 and 22, in a state that does not cause discomfort even if the user HM touches it.

[0109] At this time, the heat dissipation fan 98 draws in low-temperature outside air (air AR) from the outside through the intake section 88A described below, with a large air volume that does not cause air to stagnate inside the housing 80, and forcibly expels the exhaust air HL that has heated up inside the housing 80 out of the housing 80 through the exhaust section 88B.

[0110] (Housing body 80A) 19 and 22, the housing main body 80A has an intake section 88A formed along the outer periphery of a heat transfer plate 92 attached to one surface 93a of the Peltier element that is exposed to the outside, an intake-side flange 81, and an intake-side peripheral wall section 82. The intake-side flange 81 is formed in an annular shape along the outer periphery of the intake section 88A, inclined in a direction away from one surface 93a of the Peltier element 93 with respect to a horizontal direction parallel to the one surface 93a of the Peltier element 93. The intake-side peripheral wall section 82 is integral with the intake-side flange 81 and stands cylindrically from the inside of the intake-side flange 81.

[0111] (fixture 89) 19 and 22, fixture 89 is a fastener formed in the shape of a generally polygonal ring with the outer periphery of the ring intermittently chamfered. Fixture 89 has protrusions 91 formed in multiple locations on inner circumferential surface 89b toward axis L2. Fixture 89 has protrusions 89a provided on one end face in the axial direction AX2 (the right side in FIG. 22) and formed in a manner inclined toward the end face on the opposite side.

[0112] (Assembling the Fixture 89 and Housing 80) FIG. 23 is a perspective view showing how to attach the Peltier element unit shown in FIG. 19 to the element attachment portion of the inner fabric.

[0113] 23 and 24, a plurality of fixed guides 83 are arranged on the outer peripheral surface 82a of the intake-side peripheral wall portion 82. The diameter of the outer peripheral surface 82a of the intake-side peripheral wall portion 82 is slightly smaller than the diameter of the protrusions 91 provided on the inner peripheral surface 89b of the fixing device 89, and is sized so that the protrusions 91 and the fixed guides 83 can engage with each other.

[0114] 19, when viewed from the axial direction AX2, the fixed guide 83 extends in an arc shape between one end and the other end along the outer peripheral surface 82a of the intake-side peripheral wall portion 82, and when viewed from the radial direction RD2, the fixed guide 83 is formed in an inclined manner with respect to the horizontal. The one end and the other end of the fixed guide 83 have a difference in height in the axial direction AX2. The multiple fixed guides 83 are spaced apart at a predetermined pitch in accordance with the dimensions of the protrusion pieces 91 and are disposed in an intermittent arrangement in the axial direction AX2.

[0115] The fixed guide 83 has, on the sliding side of the protrusion piece 91 formed on the outer peripheral surface 82a of the intake-side peripheral wall portion 82, in the lead direction Le, an introduction surface 84, a first restriction surface 86a, a first holding surface 85a, a second restriction surface 86b, a second holding surface 85b, a third restriction surface 86c, and a third holding surface 85c, in this order from one end side (left side in FIG. 19). Note that in this embodiment, the fixed guide 83 is provided with three restriction surfaces 86 and three holding surfaces 85, but the number of restriction surfaces and holding surfaces is not limited to three and can be changed as appropriate.

[0116] The first holding surface 85a, the second holding surface 85b, and the third holding surface 85c are formed in a smooth surface shape to hold the protruding pieces. The first restricting surface 86a, the second restricting surface 86b, and the third restricting surface 86c are formed in a mountain shape protruding from the first holding surface 85a, the second holding surface 85b, and the third holding surface 85c.

[0117] The first restricting surface 86a, the second restricting surface 86b, the third restricting surface 86c and the stopper 87 restrict the movement of the protruding piece 91 arranged on the holding surface such as the first holding surface 85a in the lead direction Le from both sides of the protruding piece 91. In addition, the movement of the protruding piece 91 arranged on the holding surface such as the first holding surface 85a is restricted in the axial direction AX2 by contact with the adjacent fixed guide 83.

[0118] In the Peltier element unit 6, the fixing device 89 rotates about the axis L2 relative to the intake side peripheral wall portion 82 of the housing main body 80A, whereby the protruding piece 91 of the fixing device 89 engages with and is positioned in the fixing guide 83 of the intake side peripheral wall portion 82. In this way, the housing main body 80A and the fixing device 89 are assembled.

[0119] At this time, the distance in the axial direction AX2 between the fixing device 89 and the intake side flange 81 of the housing main body 80A changes depending on the position of the holding surface 85 that holds the protrusion piece 91, among the first holding surface 85a, the second holding surface 85b, and the third holding surface 85c on the fixed guide 83.

[0120] Therefore, in the body protective equipment 1, as shown in Figure 24, when the Peltier element unit 6 is attached by sandwiching the element mounting portion 15 of the inner fabric 10 between the fixing device 89 and the intake side flange 81 of the housing main body 80A, the thickness of the element mounting portion 15 that can be sandwiched can accommodate a wide range of thicknesses.

[0121] In the Peltier element unit 6, the assembly structure between the housing 80 and the fixture 89 is not limited to the engagement structure between the protrusion 91 and the fixed guide 83, as shown in the example. As long as the Peltier element unit is attached with the element mounting portion 15 of the inner fabric 10 sandwiched between them, the assembly structure between the housing and the fixture is not particularly limited and may be any.

[0122] <Regarding the fixing portion 8> 25 is a diagram showing body protective clothing constructed with the body protective structure of clothing according to an embodiment with the front body part open. As shown in Fig. 25 and Fig. 26, body protective equipment 1 can be attached and detached to clothing 102 worn by a user HM at a position corresponding to the protection area BP.

[0123] 2, the body protective equipment 1 has fastening parts 8, which are provided on the outer surface 20a of the outer fabric 20 of the main body 2, for fastening to the clothing 102 to be worn. The fastening parts 8 correspond to the fastening means according to the present disclosure. In this embodiment, the fastening parts 8 fasten the body protective equipment 1 to at least one of the inner lining and outer fabric of the clothing 102 by, for example, engaging with a hook-and-loop fastener, connecting with a snap button, or engaging a hook with a hook hole.

[0124] <Regarding Body Protective Clothing 100> Next, the body protective clothing 100 will be described with reference to Figs. 26 and 29. As shown in Fig. 26, the body protective clothing 100 is configured by adding a body protective section having a body protective function to a clothing main body 101, such as a bulletproof vest or a stab-proof vest. In the body protective clothing 100, the body protective section includes a protective member that provides at least one of a bulletproof function that can protect the wearer from flying bullets from the outside, and a stab-proof function that can protect the wearer from external harm caused by a bladed object. The protective member is made of a material according to well-known technology.

[0125] The body protection clothing 100 is configured by integrating the body protection equipment 1 as a body protection part with the clothing main body 101.

[0126] The body protective clothing is not limited to body protective clothing 100 using body protective equipment 1 as shown in Fig. 3, but may be body protective clothing 100X using body protective equipment 1X having a plurality of air outlets 14X provided in windproof fabric portion 11 as exemplified in Fig. 8 and Fig. 29. Fig. 29 is a diagram showing body protective clothing configured with the body protective structure of clothing according to an embodiment, configured with an inner fabric having air outlets according to a modified example, and shows the front of the body protective clothing in an open state.

[0127] Next, the air conditioning function of the body protective equipment 1 and the body protective clothing 100 will be described with reference to Fig. 27 and Fig. 28. Fig. 27 is a schematic diagram showing the flow of air supply and exhaust in the body protective equipment according to the embodiment, and Fig. 28 is an explanatory view taken along the arrow AA in Fig. 1, and is the same as Fig. 27, showing the flow of air supply and exhaust in the body protective equipment.

[0128] In the body protective equipment 1 and the body protective clothing 100, the air AR that flows in between the inner fabric 10 and the protective part 3 by the air blower fan unit 5 can flow out of the inner fabric 10 through the air circulation part 4 and the air outlet 14.

[0129] 27 and 28, air AR is introduced into the main body 2 by the blower fan unit 5 and sent from the air outlet area Q1 to the air intake area Q2 through the air circulation section 4. When the air AR passes through the air circulation section 4, it also flows through the air outlet 14 of the inner fabric 10 and flows out of the inner fabric 10 from the air outlet 14 as air FL. This allows the user HM to be indirectly exposed to the air FL on their back BK via their clothing.

[0130] Furthermore, within the clothing body 101 and clothing 102 of the body protective clothing 100, the cold heat exerted on the heat transfer plate 92 of the Peltier element unit 6 is transferred to the back BK of the user HM, thereby cooling the body of the user HM. Meanwhile, air AR is supplied from the outside into the Peltier element unit 6 through the intake section 88A by the heat dissipation fan 98, and exhaust air HL is discharged from the exhaust section 88B through the ventilation section 4 to the outside of the inner fabric 10 through the air outlet 14 of the inner fabric 10.

[0131] Next, the actions and effects of the body protective equipment 1, the body protective structure of the clothing, and the body protective clothing 100 according to the embodiment will be described.

[0132] The body protective equipment 1 according to this embodiment includes a main body part 2 formed by overlapping an inner fabric 10 having an air outlet 14 formed therein and an outer fabric 20 so as to be able to cover a protective area BP of the body of a user HM, including at least the back BK; a protective part 3 configured to have at least one of a bulletproof and stab-proof function; a blower fan unit 5 that sends air AR; an air circulation part 4 having a circulation path FP for the air AR; and a control part 7 that performs electrical control. In the main body part 2, the protective part 3 is disposed between the inner fabric 10 and the outer fabric 20 so as to face each other. The air circulation section 4 is arranged between the inner fabric 10 and the outer fabric 20 on the opposite side of the protective section 3, and the air supply fan unit 5 is detachably attached to the fan attachment section 21 of the main body 2, which is away from the position where the protective section 3 is arranged, and the air supply fan unit 5 allows air AR that has flowed between the inner fabric 10 and the protective section 3 to flow out of the inner fabric 10 from the air outlet 14 through the air circulation section 4, and the clothing 102 worn by the user HM and the main body 2 can be detachably attached at a position corresponding to the protective area BP.

[0133] Furthermore, the body protection structure of the clothing according to this embodiment is clothing 102 worn by a user HM, and includes a main body part 2 formed by overlapping an inner fabric 10 having an air outlet 14 formed therein and an outer fabric 20 so as to be able to cover a protection area BP of the body of the user HM, including at least the back BK, a protective part 3 configured to have at least one of a bulletproof and stab-proof function, a blower fan unit 5 that sends air AR, an air circulation part 4 having a circulation path FP for the air AR formed therein, and a control part 7 that performs electrical control, In the section 2, the protective section 3 is arranged between the inner fabric 10 and facing the outer fabric 20, and the air circulation section 4 is arranged between the inner fabric 10 on the opposite side of the outer fabric 20 sandwiching the protective section 3, and the air blower fan unit 5 is detachably attached to a fan mounting section 21 of the main body section 2 that avoids the position where the protective section 3 is arranged, and the air blower fan unit 5 allows air AR that has flowed between the inner fabric 10 and the protective section 3 to flow out of the inner fabric 10 from the air outlet 14 through the air circulation section 4.

[0134] Furthermore, the body protective clothing 100 of this embodiment is characterized in that it is a body protective clothing in which a body protective part having at least one of a bulletproof function that can protect the body from flying bullets from the outside or a blade-proof function that can protect the body from external harm caused by a bladed weapon is provided in the protective member 41, and the body protective part is body protective equipment 1 that is configured with the body protective structure of the clothing of this embodiment as described above.

[0135] Due to these features, the body protective equipment 1 and body protective clothing 100 can cover the protective area BP of the user HM, primarily targeted at people who work in jobs that require them to wear protective clothing with heavy safety equipment, such as bulletproof vests or stab-proof vests, to perform their current duties.

[0136] For example, even when a user HM is performing duties at a site exposed to the scorching sun on a scorching hot day when the outside temperature exceeds 35°C, if the user HM is wearing the body protective equipment 1 or the body protective clothing 100, the user HM can cool his / her back BK moderately by the air FL blown by the blower fan unit 5 and the cold heat received from the heat transfer plate 92 of the Peltier element unit 6.

[0137] Furthermore, in the body protective equipment 1 and the body protective clothing 100, the heat transfer plate 92 of the Peltier element unit 6 can be positioned near the nape of the neck and cervical vertebrae, which are particularly sensitive to heat, so the user HM can perform their duties without feeling uncomfortable due to the heat. Therefore, the body protective equipment 1 and the body protective clothing 100 are one of the measures to prevent heatstroke caused by extreme heat for the user HM.

[0138] Therefore, according to the body protective equipment 1, the body protective structure of the clothing, and the body protective clothing 100 of the embodiment, when worn by a user HM, they can protect themselves from external attacks and harm, like a bulletproof vest or a stab-proof vest, and even if the environment surrounding the user HM is hot, the user HM's body can be adjusted to an appropriate temperature when worn, thereby achieving the excellent effect of improving comfort.

[0139] Furthermore, in the body protective equipment 1 according to the embodiment, when the back BK of the user HM is covered by the main body part 2, and the direction corresponding to the neck side is the upper side of the main body part 2 in the back height direction HT of the user HM, and the direction corresponding to the waist side is the lower side of the main body part 2, the fan mounting part 21 has a plate-shaped core material 22 and is arranged between the lower end of the inner fabric 10 located on the lower side and the lower end of the outer fabric 20, and is characterized in that the fan mounting part 21 can be reversibly folded at the connection part 24 with the lower end of the inner fabric 10 within a rotation range toward the outside of the outer fabric 20 relative to the inner fabric 10.

[0140] 26, when a user HM wearing the body protective equipment 1 assumes a sitting position, the fan mounting part 21 can be rotated and folded at the connection part 24. This prevents the blower fan unit 5 from being crushed by the user HM as the user assumes a sitting position, and prevents damage to the blower fan unit 5.

[0141] Furthermore, in the body protective equipment according to the embodiment, the ventilation section 4 is characterized in that it is made of double Russell fabric having countless voids 55 geometrically arranged in a three-dimensional structure by Russell knitting of the fibers.

[0142] Due to this feature, when the ventilation member 51 of the air circulation section 4 is made of double raschel fabric, the air AR supplied by the blower fan unit 5 can smoothly pass through the air circulation section 4 while minimizing pressure loss when passing through the air circulation section 4. Therefore, the blown air FL can flow out from the air outlet 14 while suppressing a decrease in flow velocity and volume in the air circulation section 4.

[0143] Furthermore, the body protective equipment 1 according to the embodiment is equipped with a Peltier element unit 6 having a Peltier element 93, a heat sink 94 formed on one surface 93a of the Peltier element 93 and the other surface 93b opposite the one surface 93a, and a heat dissipation fan 98 that blows air to the heat sink 94, and is characterized in that the Peltier element unit 6 is detachably attached to the inner fabric 10 in an element mounting portion 15 formed on the inner fabric 10, with the other surface 93b side positioned between the inner fabric 10 and the protective portion 3 and the one surface 93a side positioned outside the inner fabric 10 by passing through a through hole 15H formed in the element mounting portion 15.

[0144] Due to this feature, the user HM can receive the cold heat from the heat transfer plate 92 on the back BK etc. in the Peltier element unit 6, and the cold heat from the Peltier element unit 6 can effectively cool parts of the back BK etc. that become wet with sweat and become uncomfortable due to excessive sweating.

[0145] Furthermore, the body protective equipment 1 according to the embodiment is characterized in that the air circulation section 4 is arranged in the internal space 2S of the main body section 2, which is formed by communication between the blower side area Q1 of the blower fan unit 5 and the intake side area Q2 of the heat dissipation fan 98.

[0146] Due to this feature, the exhaust air HL that has completed heat exchange with the heat sink 94 can flow out of the inner fabric 10 from the air outlet 14 of the inner fabric 10 together with the air AR supplied by the blower fan unit 5 through the ventilation section 4, in contrast to the air AR blown by the heat dissipation fan 98. At this time, the exhaust air HL is mixed with the air AR supplied from the blower fan unit 5 and flows out of the air outlet 14 in a temperature-adjusted state. Therefore, even if the exhaust air HL mixed with the air AR comes into contact with the user HM when it flows out, the exhaust heat has almost no effect on the body.

[0147] Furthermore, the body protective equipment 1 according to the embodiment is characterized in that the air outlet 14 is arranged at the upper end of the inner fabric 10 that covers the upper part of the shoulder blade BK1 within the protection area BP.

[0148] With this feature, by supplying air FL from the air outlet 14 to the upper shoulder area BK1 of the user HM, which is a body part that is particularly sensitive to heat, such as the vicinity of the cervical vertebrae of the user HM and which is prone to becoming humid due to sweat, the discomfort felt on the back BK of the user HM can be relieved, allowing the user HM to be active in comfort.

[0149] Furthermore, the body protective equipment 1 according to the embodiment is characterized in that the inner fabric 10 is composed of a mesh fabric portion 12, part of which is made of mesh fabric, and the air outlet 14 is an opening within the mesh of the mesh fabric.

[0150] Due to this feature, in the mesh fabric, the air outlets 14 are widely present across the entire fabric, so that the air FL flowing out from the air outlets 14 can reach a wider area of ​​the protected area BP of the user HM.

[0151] Furthermore, the body protective equipment 1 according to the embodiment is characterized in that the main body 2 is provided with a fastening part 8 for fastening to clothing 102 to be worn.

[0152] This feature allows the body protector 1 to be attached to a wider variety of clothing 102, even clothing 102 that does not originally have bulletproof or stab-proof functions.

[0153] Although the present disclosure has been described above based on the embodiments, the present disclosure is not limited to the above embodiments and can be appropriately modified and applied within the scope that does not deviate from the gist of the present disclosure.

[0154] For example, in the embodiment, the Peltier element unit 6 to be worn may be provided at a position other than near the upper part of the shoulder blade BK1 shown in FIG.

[0155] Furthermore, for example, in the embodiment, the protective area BP of the user HM is described as a body protective device 1 that can cover the entire back BK and the abdominal area, but the protective area of ​​the human body covered by the body protective device of the present disclosure may also be the entire back and abdominal area, plus the chest and abdomen.

[0156] That is, in order to prevent a fatal situation due to an external dangerous act, the area of ​​the human body covered by the body protective equipment according to the present disclosure must be the upper body in particular. The lower body may also be included in the protected area of ​​the human body, in which case the body protective equipment according to the present disclosure is attached to pants.
