Description
本発明は、例えば、建築、土木、工場、医療、災害、消防、警備などの現場で用いられるヘルメット、及び例えばヘルメットの顎紐などに用いられる帯紐用バックルに関する。 The present invention relates to a helmet used on the site of, for example, construction, civil engineering, a factory, medical care, disaster, fire fighting, security, and a strap buckle used for, for example, a chin strap of a helmet.
従来の一般的なヘルメットを図１２に示す。
ヘルメット１１０には、帽体の内周面に両端を連結する一対の耳紐１２０と、一対の耳紐１２０を連結する顎紐１２３とを備え、顎紐１２３に着脱用のバックル１３０が設けられている。
なお、バックルの交換を目的としたヘルメット用顎紐について提案されたものがある（特許文献１）。ここで、特許文献１には、耳紐の折り返し箇所にバックルを設け、このバックルで耳紐をＶ字状に折り返す構成が示されている（特許文献１の図８に示される従来技術）。また、特許文献１には、耳紐の折り返し箇所に調整具を設け、この調整具によって耳紐が実質的に折り返されることで、ねじれが生じにくい構成となっている（特許文献１の図１から図７に示される実施例）。
A conventional general helmet is shown in FIG.
The helmet 110 includes a pair of ear straps 120 that connect both ends to the inner peripheral surface of the cap body, and a chin strap 123 that connects the pair of ear straps 120, and a detachable buckle 130 is provided on the chin strap 123. ing.
In addition, there exists what was proposed about the chin strap for helmets aiming at the exchange of a buckle (patent document 1). Here, Patent Document 1 discloses a configuration in which a buckle is provided at a folded portion of the ear strap, and the ear strap is folded back into a V shape with this buckle (the prior art shown in FIG. 8 of Patent Document 1). Further, in Patent Literature 1, an adjustment tool is provided at a folded portion of the ear strap, and the ear strap is substantially folded by the adjustment tool, so that the twist is hardly generated (FIG. 1 of Patent Literature 1). To the embodiment shown in FIG.
従来の一般的なヘルメット１１０では、図１２の丸枠に示すように耳紐１２０にねじれを生じてしまうことが多い。また顎下に位置するバックル１３０は装脱着がしにくく、肉ばさみを起こしやすいという問題があった。
一方、特許文献１では、耳紐の折り返し箇所にバックルを設ける構成の他に、耳紐の折り返し箇所に調整具を設ける構成が示され、図１２に示される構成と比較すると耳紐にねじれを生じにくい構成となっている。
しかし、特許文献１における耳紐の折り返し箇所にバックルを設ける構成では、スリット状の長孔によって耳紐を折り返しているにすぎないため、耳紐とバックルとが滑りやすく、この滑りによって耳紐にねじれを生じる場合がある。また、特許文献１における耳紐の折り返し箇所に調整具を設ける構成では、調整具に２つの長孔が形成され、この長孔によって一端側の耳紐と他端側の耳紐とを所定角度に維持している。従って、バックルによって折り返す構成よりもねじれは生じにくいと考えられるが、調整具の折り返し箇所に配置されるリング体との位置関係によっては、耳紐とバックルとが滑りやすく、この滑りによって調整具に対して耳紐が滑ることで耳紐にねじれを生じる場合がある。
In the conventional general helmet 110, the ear strap 120 is often twisted as shown by the round frame in FIG. Further, the buckle 130 located under the chin has a problem that it is difficult to put on and take off, and easily causes meat shears.
On the other hand, in Patent Document 1, in addition to the configuration in which a buckle is provided at the folded portion of the ear strap, a configuration in which an adjustment tool is provided at the folded portion of the ear strap is shown. Compared with the configuration shown in FIG. It is difficult to generate.
However, in the configuration in which the buckle is provided at the folded portion of the ear cord in Patent Document 1, the ear cord and the buckle are easily slipped because the ear cord is merely folded back by the slit-like long hole. Twist may occur. Moreover, in the structure which provides an adjustment tool in the folding | returning location of the ear strap in patent document 1, two long holes are formed in an adjustment tool, and the ear strap of one end side and the ear strap of the other end side are formed at a predetermined angle by this long hole. To maintain. Therefore, it is considered that twisting is less likely to occur than in the configuration where the buckle is folded back.However, depending on the positional relationship with the ring body arranged at the folding position of the adjustment tool, the ear strap and the buckle can slip easily. On the other hand, the ear strap may be twisted due to the sliding of the ear strap.
そこで本発明は、耳紐にねじれを生じにくいヘルメット、及びねじれを生じにくい帯紐用バックルを提供することを目的とする。 Then, an object of this invention is to provide the helmet which does not produce twist with an ear strap easily, and the buckle for a strap which does not produce twist easily.
