Description

本発明は、作業用、運転用、スポーツ用、軍用、防災用などのヘルメットに関し、より詳しくは、不使用時にヘルメットの一部を旋回させることによって、ヘルメットの容積を減少することが可能なヘルメットに関する。   The present invention relates to helmets for working, driving, sports, military, disaster prevention, and the like, and more specifically, a helmet capable of reducing the volume of the helmet by turning a part of the helmet when not in use. About.

不使用時に、ヘルメットの容積を減少（減容）可能な機構を備えたヘルメットとして、分離式、反転式、折り畳み式など、種々の構造が開発されている。
例えば、特許文献１に記載のヘルメットは分離式のヘルメットであり、ヘルメット本体を上下方向に二分割して、上側のキャップを下側の透明防護体に係合することで一体化可能とし、不使用時には、キャップを上方から押圧することで透明防護体との係合状態を解除し、透明防護体の内部に設けた吊設体でもってキャップを吊設した状態で、透明防護体内へと収容する構造を呈している。
また、特許文献２の記載のヘルメットは反転式のヘルメットであり、ヘルメット本体を上下方向に二分割して、上側のドーム状殻部材を、下側の環状殻部材の左右方向に伸びる枢軸を介して反転可能に連結する構造を呈している。 Various structures such as a separation type, a reversing type, and a folding type have been developed as a helmet having a mechanism capable of reducing (reducing) the volume of the helmet when not in use.
For example, the helmet described in Patent Document 1 is a detachable helmet, and can be integrated by dividing the helmet body into two parts in the vertical direction and engaging the upper cap with the lower transparent protective body. When in use, press the cap from above to release the engagement with the transparent protective body, and the cap is suspended by the suspended body provided inside the transparent protective body, and then accommodated in the transparent protective body. It has a structure that
Further, the helmet described in Patent Document 2 is a reversing helmet, and the helmet body is divided into two in the vertical direction, and the upper dome-shaped shell member is connected to the lower annular shell member via a pivot that extends in the left-right direction. The structure is connected so that it can be reversed.

特開２００４−０８４１４５号公報JP 2004-084145 A 特許第５９０８９２９号公報Japanese Patent No. 5908929

しかし、特許文献１に係るヘルメットでは、以下に記載する問題のうち、少なくとも何れか１つの問題を有する。
（１）上方からの押圧力によってキャップと透明防護体との係合状態が解除されるため、落下物などの衝撃による防護機能に難がある。
（２）係合機構が甘くなると、キャップが落下するため、使用感が悪い。
（３）雨などの際に、キャップと透明防護体との係合箇所に雨が溜まりやすく、係合箇所の隙間を通ってヘルメット内部に水が漏れてしまう。
（４）吊設体によってキャップと透明防護体とを繋いでいるため、吊設体が破断して各部材が分かれてしまうと、部材の行方がわからなくなってしまう。 However, the helmet according to Patent Document 1 has at least one of the problems described below.
(1) Since the engagement state between the cap and the transparent protective body is released by the pressing force from above, there is a difficulty in a protective function due to an impact such as a falling object.
(2) When the engagement mechanism becomes sweet, the cap falls and the feeling of use is bad.
(3) In the case of rain or the like, rain easily collects at the engagement portion between the cap and the transparent protective body, and water leaks into the helmet through the gap between the engagement portions.
(4) Since the cap and the transparent protective body are connected by the suspended body, if the suspended body is broken and the members are separated, the whereabouts of the members cannot be understood.

また、特許文献２に係るヘルメットでは、以下に記載する問題のうち、少なくとも何れか１つの問題を有する。
（５）枢軸を長穴内でスライドさせてドーム状殻部材と環状殻部材との相対位置を偏移させることで、ドーム状殻部材の反転動作を実現しているため、落下物などの衝撃による上方からの押圧力によってドーム状殻部材がスライドして反転してしまう可能性があり、非反転状態で、ドーム状殻部材を位置決めするロック手段が必須となる。
（６）ドーム状殻部材と環状殻部材との相対位置を偏移させるためにドーム状殻部材と環状殻部材との接触面を平坦にする必要があり、雨などの際に、ドーム状殻部材と環状殻部材と間の隙間を通ってヘルメット内部に水が漏れやすくなる。
（７）ドーム状殻部材と環状殻部材との相対位置を偏移させることで、ドーム状殻部材の反転動作を実現しているため、非反転状態においてドーム状殻部材の前後揺動によって生じる隙間からの水漏れを回避するには、前記（５）に示すロック手段が必須となる。 Moreover, in the helmet which concerns on patent document 2, it has at least any one problem among the problems described below.
(5) The reversing operation of the dome-shaped shell member is realized by sliding the pivot in the elongated hole to shift the relative position between the dome-shaped shell member and the annular shell member. There is a possibility that the dome-shaped shell member slides and reverses due to the pressing force from above, and lock means for positioning the dome-shaped shell member in the non-inverted state is essential.
(6) In order to shift the relative position between the dome-shaped shell member and the annular shell member, it is necessary to flatten the contact surface between the dome-shaped shell member and the annular shell member. Water easily leaks into the helmet through the gap between the member and the annular shell member.
(7) Since the reversing operation of the dome-shaped shell member is realized by shifting the relative position between the dome-shaped shell member and the annular shell member, the dome-shaped shell member is caused to swing back and forth in the non-reversed state. In order to avoid water leakage from the gap, the locking means shown in (5) is essential.

以上の通り、本願発明は、容積を減少可能なヘルメットにおいて、より利便性・安全性の高いヘルメットを提供することを目的の一つとする。   As described above, an object of the present invention is to provide a helmet that can be reduced in volume and that is more convenient and safe.

上記課題を解決すべくなされた本願の第１発明は、旋回式ヘルメットであって、ヘルメット本体を上下に二分割してなる、基部および可動部と、水平方向を回転軸方向として、平行に第１の回転軸および第２の回転軸を配してなる、旋回部と、を少なくとも具備し、第１の回転軸は可動部に連結してあり、第２の回転軸は基部に連結してあり、旋回部でもって可動部を回転させて、可動部の一部または全部を非反転姿勢の状態で基部の下側から基部の内部に収容可能に構成したことを特徴とする。
また、本願の第２発明は、前記第１発明において、基部の上部に、外周側を凹部とする段差を設け、可動部の下縁を、前記凹部に嵌合して基部と可動部とを連結することを特徴とする。 The first invention of the present application to solve the above-mentioned problems is a swivel helmet, which is divided into two parts in parallel, with a base part and a movable part formed by dividing the helmet main body into two parts, and a horizontal direction as a rotation axis direction. At least a swivel portion including a first rotation shaft and a second rotation shaft, wherein the first rotation shaft is coupled to the movable portion, and the second rotation shaft is coupled to the base portion. In addition, the movable part is rotated by the turning part, and a part or all of the movable part can be accommodated in the base part from the lower side of the base part in a non-inverted posture.
Further, the second invention of the present application is the first invention, wherein a step having a concave portion on the outer peripheral side is provided at an upper portion of the base portion, and a lower edge of the movable portion is fitted into the concave portion to connect the base portion and the movable portion. It is characterized by connecting.

本願発明によれば、以下に記載する効果のうち、少なくとも何れか１つの効果を有する。
（１）ヘルメットの外表面に連続性を持たせることができる。
基部と可動部との間に介設する旋回部でもって、基部と可動部の上下関係を入れ換えることができる。
よって、基部と可動部とが完全に独立する分離式ヘルメットでなければ実現できなかったヘルメット外表面の連続性の確保を実現できる。
ヘルメット外表面の連続性を確保できると、使用状態において、基部と可動部の連結部分で外表面に段差や大きな隙間が生じることがなくなる。
（２）基部と可動部との間の隙間からの浸水がしにくい。
基部と可動部との間の隙間になる連結面が略水平面を含むため、ヘルメットの使用時に、水が隙間に侵入しにくい。
（３）ヘルメット内部にまで浸水する恐れを抑制できる。
基部に設けた段差面により、ヘルメット内部にまで浸水することがない。
（４）可動部の沈み込みを防止できる。
基部に設けた凸部を、可動部の下縁と張出部とで挟み込むため、上方からの押圧力に対して、可動部が開いて下方に沈み込むことがない。 According to this invention, it has at least any one effect among the effects described below.
(1) The outer surface of the helmet can have continuity.
With the swivel part interposed between the base part and the movable part, the vertical relationship between the base part and the movable part can be exchanged.
Therefore, it is possible to secure the continuity of the outer surface of the helmet that could not be realized unless the base and the movable part are completely separated from each other.
If the continuity of the outer surface of the helmet can be ensured, a step or a large gap is not generated on the outer surface at the connecting portion between the base and the movable part in the use state.
(2) It is difficult for water to enter from the gap between the base and the movable part.
Since the connection surface which becomes a clearance gap between a base and a movable part contains a substantially horizontal surface, at the time of use of a helmet, it is hard for water to penetrate | invade into a clearance gap.
(3) The risk of flooding into the helmet can be suppressed.
The stepped surface provided at the base does not flood the helmet.
(4) The moving part can be prevented from sinking.
Since the convex portion provided on the base portion is sandwiched between the lower edge of the movable portion and the protruding portion, the movable portion does not open and sink downward with respect to the pressing force from above.
