Description
本発明は、例えば地震や火災の防災時や各種作業時に用いられる折り畳み安全帽に関する。 The present invention relates to a folding safety cap used, for example, at the time of disaster prevention of earthquakes and fires and various work.
従来から、折り畳み可能なヘルメットとしていくつかのタイプが提案されている。
例えば、第１のタイプとして、特許文献１では、頭頂部を分割中心として、ヘルメット本体を複数の部材に分割し、組み立て可能な構成が提案されている。
第１のタイプとしては、その他の構成として、頭頂部を分割中心としたそれぞれの部材を、頭頂部に設けた軸を中心に回動可能とすることで、それぞれの部材を重ね合わせて収納する構成が提案されている（例えば特許文献２、３、４）。
また、第２のタイプとしては、頭頂部の代わりに、両側頭部の位置を回動軸として、それぞれの部材を重ね合わせて収納する構成が提案されている（例えば特許文献５、６、７）。
また、第３のタイプとしては、頭頂部を中心として水平面でヘルメット本体をいくつかの部材に分割し、これらの部材を重ね合わせることで収納する構成が提案されている（例えば特許文献８、９、１０）。
また、第４のタイプとして、前側弾性平板と後側弾性平板の２つの部材で構成し、使用時である展開状態では、この２つの部材の弾性力を利用して湾曲状態を維持し、未使用時である折り畳んだ状態では扁平状態となる構成が提案されている（特許文献１１、１２）
For example, as a first type, Patent Document 1 proposes a structure that can be assembled by dividing the helmet body into a plurality of members with the top of the head as the division center.
As a 1st type, as another structure, each member centering on a parietal part can be rotated centering on the axis | shaft provided in the parietal part, and each member is piled up and stored. A configuration has been proposed (for example, Patent Documents 2, 3, and 4).
In addition, as a second type, a configuration in which the respective members are stacked and stored using the positions of the heads on both sides instead of the top of the head as rotation axes has been proposed (for example, Patent Documents 5, 6, and 7). ).
In addition, as a third type, a configuration in which the helmet body is divided into several members on a horizontal plane centering on the top of the head and the members are stored by overlapping these members is proposed (for example, Patent Documents 8 and 9). 10).
Further, as a fourth type, it is composed of two members, a front elastic plate and a rear elastic plate, and in a deployed state at the time of use, the curved state is maintained by utilizing the elastic force of these two members. The structure which becomes a flat state in the folded state which is the time of use is proposed (patent documents 11 and 12).
しかし、既に提案されている第１のタイプから第３のタイプの構成では、折り畳んだ状態でヘルメットとしての湾曲形状が残存しているために収納しにくく、または、湾曲形状が残らないほど分割しているものは保護機能が十分でないという問題がある。
また、第４のタイプでは、折り畳んだ状態で扁平となるとともに２つに分割しているだけなので保護機能にも優れていると考えられるが、折り畳んだ状態での面積が大きくなってしまうという問題がある。
However, in the configurations of the first type to the third type that have already been proposed, the curved shape as a helmet remains in a folded state, so that it is difficult to store or is divided so that the curved shape does not remain. The problem is that the protection function is not sufficient.
In the fourth type, it is flat when folded and it is only divided into two, so it is considered to be excellent in protection function, but the problem is that the area in the folded state increases. There is.
そこで本発明は、保護機能にも優れているとともに、収納時に扁平状態となり、更に折り畳んだ状態での面積も小さくなる折り畳み安全帽を提供することを目的とする。 SUMMARY OF THE INVENTION An object of the present invention is to provide a folded safety cap that has an excellent protective function, is flat when stored, and has a smaller area when folded.

In addition to the above, it may be connected by an elastic member.
The side plate bent portion 43 is formed by integrally forming the front side plate 41 and the rear side plate 42 with the same material, and between the front side plate 41 and the rear side plate 42. You may comprise so that it may have flexibility.
上記構成により、特に図３に示すように、第１の状態では、前面板部１０と、後面板部２０と、一対の側面板部４０とによって頭部を覆う空間６１が形成される。
空間６１には、図３に示すように着装体６２を備える。着装体６２は、前面板部１０と、後面板部２０と、一対の側面板部４０とによって構成される帽体とのバランスを維持するハンモックの機能を備えていることが好ましく、少なくともヘッドバンドや顎紐６３を有する。着装体６２は、衝撃吸収ライナーとしての機能を有するものであってもよい。顎紐６３の両端は、着装体６２に取り付けられ、一対の側面板部４０に対応する位置に配置される。
帽体を構成する、前面板部１０、後面板部２０、一対の側面板部４０の材質は、ポリカーボネート、ポリエチレン、アクリロニトリル・ブタン・スチレンなどの熱可塑性樹脂、ポリエステル樹脂をガラス繊維で強化した熱硬化性樹脂が適している。
With the above configuration, as shown particularly in FIG. 3, in the first state, a space 61 that covers the head is formed by the front plate portion 10, the rear plate portion 20, and the pair of side plate portions 40.
As shown in FIG. 3, the space 61 includes a wearing body 62. The wearing body 62 preferably has a hammock function for maintaining a balance with the cap body constituted by the front plate portion 10, the rear plate portion 20, and the pair of side plate portions 40, and at least a headband. And a chin strap 63. The wearing body 62 may have a function as an impact absorbing liner. Both ends of the chin strap 63 are attached to the wearing body 62 and arranged at positions corresponding to the pair of side surface plate portions 40.
The material of the front plate part 10, the rear plate part 20, and the pair of side plate parts 40 constituting the cap body is a thermoplastic resin such as polycarbonate, polyethylene, acrylonitrile / butane / styrene, or a heat reinforced polyester resin with glass fiber. A curable resin is suitable.
次に、図４から図７を用いて本実施例による折り畳み安全帽の第２の状態への動作について説明する。なお、図７が扁平状態となる第２の状態を示している。
側面板折曲部４３を空間６１側に移動させるように折曲させることで、前方折曲部５１及び後方折曲部５２も折曲し、前方側側面板部４１は前面板部１０に近接するように、後方側側面板部４２は後面板部２０に近接するように移動する。
このとき、一対の側面板折曲部４３は、それぞれが当接しない状態に配置されることが好ましい。一対の側面板折曲部４３を当接させないためには、一方の側面板折曲部４３を構成する前方側側面板部４１と、他方の側面板折曲部４３を構成する前方側側面板部４１との寸法を異ならせることによっても実現できるが、本実施例では、前面板部１０及び後面板部２０のねじれと前方折曲部５１及び後方折曲部５２の可撓性によって実現している。
上記動作に伴い、前方未補強部１３と後方未補強部２３によって生じていた湾曲状態は無くなり、第２の状態では、前面板部１０と後面板部２０とが扁平状態で近接対向する。なお、一対の側面板部４０は、前面板部１０と後面板部２０との間に配置させる。
Next, the operation | movement to the 2nd state of the folding safety hat by a present Example is demonstrated using FIGS. 4-7. FIG. 7 shows a second state where the flat state is reached.
By bending the side plate bent portion 43 so as to move to the space 61 side, the front bent portion 51 and the rear bent portion 52 are also bent, and the front side plate portion 41 is close to the front plate portion 10. As described above, the rear side plate portion 42 moves so as to approach the rear plate portion 20.
At this time, it is preferable that the pair of side plate bent portions 43 be arranged in a state where they do not contact each other. In order to prevent the pair of side plate bent portions 43 from coming into contact, the front side plate 41 constituting the one side plate bent portion 43 and the front side plate constituting the other side plate bent portion 43 are provided. This can be realized by making the dimensions different from those of the portion 41, but in this embodiment, it is realized by the torsion of the front plate portion 10 and the rear plate portion 20 and the flexibility of the front bent portion 51 and the rear bent portion 52. ing.
With the above operation, the curved state generated by the front unreinforced portion 13 and the rear unreinforced portion 23 disappears, and in the second state, the front plate portion 10 and the rear plate portion 20 are opposed to each other in a flat state. The pair of side surface plate portions 40 is disposed between the front surface plate portion 10 and the rear surface plate portion 20.
以上のように本実施例によれば、前面板部１０の一辺１０Ａと後面板部２０の一辺２０Ａとが頭頂折曲部３０によって連結され、前面板部１０の側辺１０Ｃと後面板部２０の側辺２０Ｃとが側面板部４０によって連結され、第１の状態では、前面板部１０と、後面板部２０と、一対の側面板部４０とによって空間６１が形成され、第２の状態では、前面板部１０と後面板部２０とを近接対向させ、一対の側面板部４０を前面板部１０と後面板部２０との間に配置させている。それにより、前面板部１０と後面板部２０と一対の側面板部４０とによって頭部を覆う空間６１を形成して安全帽として用いることができるとともに、前面板部１０と後面板部２０とを近接対向させ、一対の側面板部４０を前面板部１０と後面板部２０との間に配置させることによって扁平状態となるため収納性に優れている。
また本実施例によれば、一対の側面板部４０に顎紐６３の両端を配置することで、前面板部１０を前頭部に配置し、後面板部２０を後頭部に配置することになり、前頭部及び後頭部の保護性能を高めることができる。
また本実施例によれば、前面板部１０の他辺１０Ｂには前面他辺側補強部１１を、後面板部２０の他辺２０Ｂには後面他辺側補強部２１を形成することで、前面板部１０と後面板部２０の強度を高めることができる。
また本実施例によれば、前面板部１０及び後面板部２０が、第１の状態では湾曲状態となり、第２の状態では扁平状態となることで、使用時には頭部にあわせた状態とすることができるとともに、収納性にも優れている。
また本実施例によれば、側面板部４０の前方側辺４０Ａと前面板部１０の側辺１０Ｃとが前方折曲部５１によって連結され、側面板部４０の後方側辺４０Ｂと後面板部２０の側辺２０Ｃとが後方折曲部５２によって連結され、側面板部４０には、側面板折曲部４３が形成されているので、収納時となる第２の状態において、側面板部４０を前面板部１０と後面板部２０との間に配置しやすく、第１の状態と第２の状態との動作をスムーズに行わせることができる。
また本実施例によれば、前方折曲部５１を前面板部１０の他辺１０Ｃ側に形成して、前面板部１０の一辺１０Ａ側と側面板部４０とを連結せず、後方折曲部５２を後面板部２０の他辺２０Ｂ側に形成して、後面板部２０の一辺２０Ａ側と側面板部４０とを連結しないことで、前方折曲部５１及び後方折曲部５２を他辺１０Ｂ、２０Ｂ側だけに設けることで、第１の状態と第２の状態との動作を更にスムーズに行わせることができる。
また本実施例によれば、前面板部１０の側辺１０Ｃにおける一辺１０Ａ側には前面側辺側補強部１２を、後面板部２０の側辺２０Ｃにおける一辺２０Ａ側には後面側辺側補強部２２を形成し、前方折曲部５１と前面側辺側補強部１２との間に前方未補強部１３を、後方折曲部５２と後面側辺側補強部２２との間には後方未補強部２３を形成したことで、前面板部１０及び後面板部２０の強度を高めるとともに、前方未補強部１３と後方未補強部２３において、湾曲状態を形成しやすくなり、頭部へのフィット感を高めることができる。
