  The present invention relates to a protective cap that is attached to a wearer's head inside a face protector, and a face protector with a protective cap.

  Conventionally, a face protector for protecting the occipital region is used for the purpose of preventing an injury such as a concussion caused by a player hitting the occipital region during a martial arts match or practice such as arrest or karate. Patent Document 1 discloses a protective structural member provided so as to cover the face of the athlete, a occipital protective cushion material extending from the protective structural member so as to cover the occipital back of the athlete, a protective structural member, and a occipital protective cushion There is described a face protector that includes a band member that is connected to a material and that has the protection structure member and a occipital region protection cushion material fixed to a player's head. In this face protector, the occipital cushion material is attached to the protective structure member itself, and the occipital cushion member absorbs an impact on the occipital back of the athlete, thereby preventing injury such as concussion in the athlete.

JP 2008-12178 A

  In the face protector described in Patent Document 1, since the occipital protective cushion material as the occipital shock absorbing material is attached to the protective structural member itself, the protective structural member is displaced during a game or practice related to the above martial arts. There is a possibility that the occipital shock absorbing material located so as to cover the occipital region is displaced from an appropriate position, and thus the occipital region cannot be effectively protected.

  The present invention has been made from the above viewpoint, and an object of the present invention is to provide a protective cap and a surface protector with a protective cap capable of suppressing displacement of the occipital shock absorber.

  As a means for solving the above problems, the present inventor attaches a protective cap to the head of the player inside the face protector, and the protective cap has a occipital shock absorber. It came to conceive the position shift of the occipital shock absorber. Specifically, the athlete wears a protective cap separate from the face protector inside the face protector, and the occipital shock absorbing material of the protective cap is arranged so as to cover the athlete's back head. Even if the face protector is displaced during the martial arts match or practice, the displacement of the protective cap separate from the face protector can be kept relatively small. The amount can be kept small.

  However, although the above-mentioned protective cap can suppress the amount of displacement of the occipital shock absorbing material during a martial arts game or practice as compared with the case where the occipital shock absorbing material is attached to the face protector, the protective cap does not compete. Since there is a occipital shock absorber located on the occipital side of the person, there is a possibility that the protective cap may be displaced in the face protector during a game or practice related to the above martial arts, and the positional displacement of the occipital shock absorber accompanying this is Unavoidable.

  Therefore, the present invention is a protective cap that is mounted on the wearer's head inside the face protector, and is attached to the cap body that covers the wearer's head and the back of the cap body in the front-rear direction. In addition, it is located so as to cover the occipital region of the wearer, and connects the occipital region shock absorbing material that absorbs the impact to the occipital region and the left and right sides of the cap body, and is hooked on the jaw portion of the wearer. And a holding part for restricting displacement of the cap main body and the occipital shock absorber.

  In the protective cap described above, the holding portion that connects the left and right sides of the cap body and is hooked to the wearer's jaw while protecting the wearer's back of the head with a back head shock absorber attached to the back of the cap body in the front-rear direction. Thus, the displacement of the cap body and the occipital shock absorber can be regulated. Thereby, it is possible to prevent the occipital shock absorber from shifting from an appropriate position during a game or practice related to the above martial arts, and it is possible to appropriately protect the wearer's head.

  It is preferable that a jaw impact absorbing material that absorbs an impact on the jaw is attached to a portion of the holding portion that contacts the jaw of the wearer.

  In the protective cap described above, the martial arts described above have a rational configuration in which the jaw impact absorbing material is attached to the holding portion that is hooked to the wearer's jaw portion in order to regulate the displacement of the cap body and the occipital impact absorbing material. The impact on the jaw during a game or practice is absorbed, thereby preventing injuries such as chronic traumatic encephalopathy.

  The cap main body has a bag-shaped accommodation portion that is provided so as to hang downward from the back in the front-rear direction of the cap main body and that is open on a surface in contact with the head of the wearer. It is preferable that the storage unit is detachably accommodated.

  In the above-described protective cap, the cap body has a bag-shaped housing portion that is open on the surface of the cap body that contacts the wearer's head, so that the wearer can accommodate the occipital shock absorber in the housing portion. By mounting the cap main body, the housing portion is blocked by the wearer's head, thereby preventing the occipital shock absorbing material from coming out of the housing portion without fixing the occipital shock absorbing material to the cap body. . Further, in the above-described protective cap, the occipital shock absorbing material is detachably accommodated with respect to the accommodating portion, so that the cap body and the occipital impact absorbing material can be separated and washed.

  The occipital shock absorber includes a first shock absorber, a second shock absorber, and a third shock absorber that overlap in the front-rear direction of the cap body, and the first shock absorber and the second shock absorber. The third shock absorbers are arranged in this order from the side near the back of the wearer, the first shock absorbers are made of foamed resin, and the second shock absorbers are synthetic resin and rubber. It is preferable that the third shock absorber is made of a synthetic resin.

  A face protector with a protective cap according to the present invention is attached to the wearer's head so as to cover the protective cap according to the present invention and the back head impact at the rear of the cap body in the front-rear direction. A surface protector from which an absorbent material is exposed, and a fixing member that is provided so as to surround the surface protective device and the occipital shock absorber, and that fixes the surface protector to the head of the wearer. The occipital shock absorber is deformed so as to contact the occipital region of the wearer.

  In the above-mentioned face protector with a protective cap, a game relating to the above martial arts is performed by using a fixing member that fixes the face protector to the wearer's head and deforming the occipital shock absorber so as to contact the wearer's occipital area. Alternatively, during practice, the occipital shock absorber can be more effectively prevented from shifting from an appropriate position, and the impact on the wearer's occipital region can be more effectively absorbed.

  As described above, according to the present invention, it is possible to provide a protective cap and a face protector with a protective cap that can effectively suppress the displacement of the occipital shock absorber.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. However, for convenience of explanation, the drawings referred to below show simplified main components necessary for explaining the present invention among the constituent members of one embodiment of the present invention. Therefore, the protective cap according to the present invention and the surface protector with the protective cap may include arbitrary components not shown in the drawings referred to in this specification.

  The face protective equipment X1 with a protective cap according to the present embodiment is a kind of protective equipment worn by a player during a game or practice related to martial arts such as arrest or karate.

  As shown in FIGS. 1 to 4, the face protector with protective cap X <b> 1 includes a protective cap 1, a face protector 3, and a fixing member 5. The wearer of the face protector X1 with the protective cap attaches the protective cap 1 to the head 100, attaches the face protector 3 to the head 100 from above the protective cap 1, and attaches the face protector 3 to the head by the fixing member 5. By fixing to the part 100, the game or practice regarding said martial arts can be performed, protecting the said head 100. FIG.

  First, the protective cap 1 will be described in detail with reference to FIGS. 3 and 4. The protective cap 1 includes a cap body 11, a occipital shock absorber 12, a holding portion 13, and a jaw impact absorber 14.

  The cap body 11 is a part that covers the wearer's head 100 from above the wearer. Specifically, the cap body 11 is covered so as to cover a portion near the top of the head 100 of the wearer, and the face 300 of the wearer is exposed from the cap body 11. In the present embodiment, a part of each of the wearer's ears is exposed from the cap body 11.

  In addition, about the shape of the cap main body 11, it does not specifically limit, For example, the said cap main body 11 may completely cover a wearer's both ears.

  The cap main body 11 has an accommodating portion 11a for accommodating a occipital shock absorber 12 described later. The accommodating part 11a is a bag-shaped part provided so that a part of surface which touches a wearer's head 100 among the cap main bodies 11 may open. The accommodating portion 11a hangs downward from the back of the cap body 11 in the front-rear direction, that is, from the wearer's back head 500 side.

  The occipital shock absorber 12 is a member that absorbs an impact on the wearer's occipital head 500. The occipital shock absorber 12 is detachably accommodated in the accommodating portion 11a of the cap main body 11 from the side of the cap main body 11 in contact with the wearer's head 100. And when a wearer covers the said cap main body 11 in the state in which the back head shock absorber 12 was accommodated in the accommodating part 11a of the cap main body 11, the accommodating part 11a was obstruct | occluded by the wearer's head 100, thereby. The occipital shock absorber 12 is surrounded by the accommodating portion 11a and the wearer's head 100.

  The occipital shock absorber 12 may be entirely accommodated in the accommodating portion 11a, or only a part of the occipital impact absorbing material 12 may be accommodated in the accommodating portion 11a. In other words, at least a part of the occipital shock absorber 12 may be held in the cap body 11 by being accommodated in the accommodating portion 11a.

  The occipital shock absorber 12 is positioned along the occipital region 500 of the wearer. In the present embodiment, the occipital shock absorber 12 is provided in a region extending from the top of the wearer to the neck, and is positioned so as to cover the occipital region 500 in the region. For this reason, even when the wearer hits the back of the head 500 by falling backward, for example, during a game or practice related to the martial arts described above, the back of the head shock absorber 12 absorbs the impact caused by the hit, and the back of the head 500 Can be prevented from being subjected to a large impact.

  As shown in FIG. 5, the occipital shock absorber 12 includes a first shock absorber 12A, a second shock absorber 12B, and a third shock absorber 12C. The first shock absorber 12A, the second shock absorber 12B, and the third shock absorber 12C overlap each other in the front-rear direction of the cap body 11, that is, in the front-rear direction of the wearer.

  12A of 1st shock absorbers are located in the side nearest the wearer's back head 500 among the 1st-3rd shock absorbers 12A-12C. The first shock absorber 12A has a rectangular shape extending along the vertical direction. In the present embodiment, the material of the first shock absorber 12A is a foamed resin, more preferably urethane foam (urethane foam).

  The second shock absorber 12B is located between the first shock absorber 12A and the third shock absorber 12C. The second shock absorber 12B has a rectangular shape extending along the vertical direction. The lower end portion of the second shock absorber 12B is positioned above the vertical direction as compared to the lower end portion of the first shock absorber 12A. In the present embodiment, the material of the second shock absorber 12B is a composite of synthetic resin and rubber, and more preferably a composite of acrylic resin, urethane resin, and rubber.

  12C of 3rd shock absorbers are located in the furthest side from the wearer's back head 500 among the 1st-3rd shock absorbers 12A-12C. The third shock absorber 12C has a rectangular shape extending in the vertical direction, and has substantially the same shape as the second shock absorber 12B. The lower end portion of the third shock absorber 12C is located above the lower end portion of the first shock absorber 12A in the vertical direction, similarly to the lower end portion of the second shock absorber 12B. In the present embodiment, the material of the third shock absorber 12C is a synthetic resin, preferably ethylene vinyl acetate (EVA).

  Here, in the present embodiment, as described above, the lower end portion of the second shock absorber 12B and the lower end portion of the third shock absorber 12C are positioned above the vertical direction as compared to the lower end portion of the first shock absorber 12A. Therefore, the lower end portion of the occipital shock absorbing material 12 becomes a concave step portion 12a that is thinner than the portion other than the lower end portion of the occipital shock absorbing material 12.

  In addition, each shape, thickness, etc. of 1st-3rd impact-absorbing material 12A-12C are arbitrary, According to the usage condition of the protective cap 1, it can change suitably. Further, the occipital shock absorber 12 does not have to have a three-layer structure including the first to third shock absorbers 12A to 12C, and may be constituted by, for example, a single shock absorber.

  The holding part 13 is a part that regulates displacement of the cap main body 11 and the occipital shock absorber 12. In the present embodiment, the holding portion 13 is integral with the cap body 11. The holding part 13 connects the left and right side parts of the cap body 11. Specifically, the holding | maintenance part 13 has connected some parts of the cap main body 11 located ahead of a wearer's both ears. The holding portion 13 extends along both cheeks of the wearer and is hooked on the jaw portion 700 of the wearer. Thus, even when the wearer's head 100 moves violently during a game or practice related to the above martial arts, the cap body 11 and the occipital shock absorber 12 attached to the cap body 11 are displaced. Can be suppressed.

  Note that the holding unit 13 may not be integral with the cap body 11, and may be a separate body from the cap body 11. For example, the rubber member may be used as the holding portion 13 by connecting one end and the other end of the string-like rubber member to the left and right side portions of the cap body 11.

  The jaw impact absorbing material 14 is a member that absorbs an impact on the wearer's jaw 700. The jaw impact absorbing material 14 is attached to a portion of the holding portion 13 that contacts the wearer's jaw 700. In the present embodiment, the jaw impact absorbing member 14 has a crescent shape, and the holding portion 13 corresponding to the jaw 700 in a state where the inner arc of the crescent shape faces upward in the vertical direction of the wearer. Installed. Thereby, it is possible to absorb an impact such as a blow on the jaw 700 of the wearer during the martial arts game or practice. In the present embodiment, the material of the jaw shock absorber 14 is the same as that of the second layer of the occipital shock absorber 12, that is, the second shock absorber 12B. That is, as the jaw impact absorbing material 14, a composite of synthetic resin and rubber, more preferably a composite of acrylic resin, urethane resin, and rubber is used.

  The shape or thickness of the jaw impact absorbing material 14 is arbitrary, and can be appropriately changed according to the usage mode of the protective cap 1.

  Next, the face protector 3 and the fixing member 5 will be described in detail with reference to FIGS. 1 and 2.

  The face protector 3 is a protector that protects the wearer's head 100 or throat during a game or practice related to the above martial arts. The face protector 3 includes an armor body that is mounted on the wearer's head 100 so as to cover the protective cap 1, and a lattice portion 31 that is attached to one surface of the armor body.

  The lattice portion 31 is a portion facing the wearer's face 300, and is formed of, for example, a metallic lattice. A wearer of the protective cap-equipped face protector X1 can perform a game or practice related to the above martial arts while facing the front from the gap in the lattice portion 31 of the face protector 3.

  Here, the armor body has an open portion 32 on the side opposite to the lattice portion 31. The opening part 32 is located on the wearer's back head 500 side, and is a part that communicates the inside and the outside of the face protector 3. In a state where the wearer wears the face protector 3, the accommodating portion 11 a in which the occipital shock absorbing material 12 is accommodated is exposed to the outside of the face protector 3 through the opening portion 32.

  The fixing member 5 is a member that fixes the face protector 3 to the wearer's head 100. In the present embodiment, the string-like fixing member 5 is wound so as to surround the face protector 3 in the circumferential direction of the wearer's head 100, and one end of the fixing member 5 on the occipital region 500 side of the wearer. The other end is tied. Thereby, the face protector 3 is fixed to the wearer's head 100, and the head 100 can be prevented from slipping out of the face protector 3 through the opening portion 32. Here, the recessed step 12a of the occipital shock absorber 12 is positioned between the occipital region 500 of the wearer and the fixing member 5 positioned on the occipital region 500 side. The occipital shock absorber 12 is deformed so as to be in contact with the occipital region 500 when the concave step portion 12 a of the occipital region shock absorber 12 is pressed against the occipital region 500 by the fixing member 5.

  In addition, the fixing member 5 does not need to be a string shape, and may be configured by, for example, an annular band member.

  As described above, in the protective cap 1, the protective cap 1 is configured separately from the face protector 3, and the cap body 11 is protected by the holding portion 13 while protecting the wearer's occipital region 500 with the occipital region shock absorber 12. Since the displacement of the occipital shock absorber 12 can be restricted, the positional deviation of the occipital shock absorber 12 can be effectively suppressed. Specifically, the wearer of the protective cap-equipped surface protector X1 wears a protective cap 1 separate from the protective surface protector 3 inside the protective surface protector 3, and the protective cap 1 is attached to the occipital shock absorber 12. Therefore, even if the face protector 3 is displaced during the martial arts game or practice, the amount of displacement of the protective cap 1 separate from the face protector 3 can be kept relatively small. The amount of displacement of the occipital shock absorber 12 provided in the cap 1 can also be kept relatively small. Furthermore, in the protective cap 1, since the holding portion 13 that connects the left and right side portions of the cap body 11 is hooked on the wearer's jaw 700, the displacement of the cap body 11 and the occipital shock absorber 12 is restricted. It can suppress that absorber 12 shifts from an appropriate position. For this reason, according to the protective cap 1, the wearer's occipital region 500 can be appropriately protected.

  Further, the protective cap 1 has a simple configuration in which the jaw impact absorbing member 14 is attached to a portion of the holding portion 13 corresponding to the wearer's jaw 700, and the cap body 11 and While restricting the displacement of the occipital shock absorbing material 12, it is possible to absorb the impact on the jaw 700, thereby suppressing injuries such as chronic traumatic encephalopathy.

  Furthermore, in the protective cap 1, since the wearer wears the cap body 11 while the occipital shock absorber 12 is accommodated in the accommodating portion 11a, the accommodating portion 11a is blocked by the wearer's head 100. Even if the shock absorber 12 is not fixed to the cap main body 11, the occipital shock absorber 12 can be prevented from coming out of the housing portion 11a. Further, in the protective cap 1, the occipital shock absorbing material 12 is detachably accommodated in the accommodating portion 11a, so that the cap body 11 and the occipital impact absorbing material 12 can be separated and washed.

  Further, the protective cap 1 includes a first shock absorber 12A made of foamed resin (for example, urethane foam) and a composite of synthetic resin and rubber (for example, a composite of acrylic resin, urethane resin, and rubber). Since the occipital shock absorber 12 has a three-layer structure in which a second shock absorber 12B and a third shock absorber 12C made of a synthetic resin (for example, ethylene vinyl acetate) are laminated, The impact on the back head 500 can be effectively absorbed, and the protection performance of the back head 500 can be improved.

  Furthermore, in the face protection device X1 with the protection cap 1 provided with the protection cap 1, the occipital shock absorber 12 is attached to the wearer's occipital region 500 using the fixing member 5 for fixing the surface protection device 3 to the wearer's head 100. Therefore, it is possible to more effectively prevent the occipital shock absorber 12 from shifting from an appropriate position during a martial arts game or practice, and to reduce the impact on the wearer's occipital region 500. It can be absorbed more effectively.

  In the above description, the protective cap 1 and the surface protector with protective cap X1 according to the present embodiment have been described in detail. However, the protective cap and the surface protector with protective cap according to the present invention are not limited thereto, and various Can be modified.

  In the protective cap 1 according to the above-described embodiment, the cap main body 11 includes the accommodating portion 11a, and the occipital shock absorbing material 12 is accommodated in the accommodating portion 11a. It is only necessary that 12 is attached to the cap body 11.

  For example, as shown in FIG. 6, the protective cap 1 may include a cap body 15 and a occipital shock absorber 16 instead of the cap body 11 and the occipital shock absorber 12 in the above embodiment. Specifically, in the protective cap 1 shown in FIG. 6, the cap body 15 does not have a housing portion, and the cap body 15 and the occipital shock absorber 16 are provided separately. On the outer surface of the cap body 15, for example, an attachment portion 15 a made of a loop of a hook-and-loop fastener is provided. The occipital shock absorbing material 16 separate from the cap body 15 has a mounting portion 16a made of hooks of, for example, hook-and-loop fasteners, and the mounting portion 16a is affixed to the mounting portion 15a. An absorbent material 16 is attached to the cap body 15. Further, the occipital shock absorber 16 has a winding fixing portion 16b that extends downward in the vertical direction at the lower end thereof. As shown in FIG. 7, the winding fixing portion 16 a is wound around the fixing member 5 positioned on the back head 500 side in the face protection device X1 with the protection cap 1 shown in FIG. 6. The shock absorber 16 is held by the cap body 15 and the fixing member 5.

  A test for confirming the impact absorbing performance of the protective cap 1 according to the present embodiment was performed. Specifically, first, a test body having the same structure as the protective cap 1 according to the present embodiment was prepared. Of the occipital shock absorber 12 in the test body, the first shock absorber 12A is made of foamed urethane (urethane foam), and the second shock absorber 12B is made of a composite of acrylic resin, urethane resin, and rubber. The third shock absorber 12C is made of ethylene vinyl acetate (EVA). Next, the occipital shock absorber 12 was placed along the occipital region of the humanoid model by mounting the test body on the humanoid model's head. Then, a plane striker having a weight of 5 kg from a height of 300 mm was freely dropped with respect to the occipital region of the humanoid model, and an impact force waveform at the occipital region was measured.

  FIG. 8 is a graph showing the measurement result of the impact force waveform. In FIG. 8, the impact force waveform is shown by a vertical axis of 3 kN / div and a horizontal axis of 2 ms / div. In addition, in FIG. 8, the measurement result at the time of performing the test similar to the above with respect to the human body model which does not wear the test body of the protective cap 1 which concerns on this embodiment as a comparative example of a present Example is also shown. .

  As shown in FIG. 8, the maximum value of the impact force at the back of the human body model when the test body of the protective cap 1 according to the present embodiment is mounted is 2.84 kN, which is the maximum value in the comparative example. It was significantly smaller than 73 kN. From this result, according to the protective cap 1 according to the present embodiment, it was confirmed that the impact on the wearer's occipital region 500 can be effectively absorbed, and thus the occipital region 500 can be effectively protected.
