Description

本発明は、ヘルメットの改良に関する。 The present invention relates to an improvement of a helmet.

近年、自転車レースや車椅子レースが盛んに開催される様になってきた。レーサー（レース参加者）は頭部保護のためにヘルメットを着用する。このためのヘルメットとして後部に整流部材を一体的に備えた物が知られている（例えば、特許文献１参照。）。
米国特許第４９０３３５０号明細書（図６） In recent years, bicycle races and wheelchair races have been actively held. Racers (race participants) wear helmets to protect their heads. As a helmet for this purpose, there is known a helmet integrally provided with a rectifying member at the rear part (for example, see Patent Document 1).
US Pat. No. 4,903,350 (FIG. 6)

特許文献１を次図に基づいて説明する。
図７は従来の技術の基本原理を説明する図である。
（ａ）に示すとおり、従来のレース用ヘルメット１００は、レーサーＭの頭に載せるヘルメット本体１０１から後方へ整流部材１０２を延出した流線形ヘルメットである。
自動二輪車用ヘルメットは整流部材１０２を備えていないため、ヘルメットの後方に渦が発生し、走行抵抗は大きい。人力（脚力又は腕力）のみを駆動源とする自転車又は車椅子では、走行抵抗の増加は、車速の低下に繋がり、レーサーの疲労の要因となるため、低減する必要がある。この低減策として整流部材１０２が考案された。 Patent document 1 is demonstrated based on the following figure.
FIG. 7 is a diagram for explaining the basic principle of the prior art.
As shown to (a), the conventional racing helmet 100 is a streamline helmet which extended the rectification | straightening member 102 back from the helmet main body 101 mounted on the racer's M head.
Since the motorcycle helmet does not include the rectifying member 102, a vortex is generated behind the helmet, and the running resistance is large. In a bicycle or wheelchair that uses only human power (leg strength or arm strength) as a driving source, an increase in running resistance leads to a decrease in vehicle speed and causes a racer's fatigue, so it needs to be reduced. A rectifying member 102 has been devised as a reduction measure.

（ｂ）は従来のヘルメットの問題点を説明する図であり、レーサーＭは加速や追い込みの際に頭を下げることがある。このときには、整流部材１０２が立ち上がり走行風をフルに受けることになる。 (B) is a figure explaining the problem of the conventional helmet, and the racer M may bow his head during acceleration or driving. At this time, the rectifying member 102 rises and fully receives the traveling wind.

加速を促すために頭を下げたのに、走行抵抗が増加することは好ましいことではない。 It is not preferable that the running resistance increases even though the head is lowered to promote acceleration.

本発明は、乗員の姿勢が変化しても走行抵抗の増加を抑えることができるヘルメットを提供することを課題とする。 This invention makes it a subject to provide the helmet which can suppress the increase in driving | running | working resistance, even if a passenger | crew's attitude | position changes.

請求項１に係る発明は、頭に被せる、ほぼ半球形状のヘルメット本体と、このヘルメット本体から後方へ延出すると共に上下スイング可能にヘルメット本体に係止した整流部材とから構成したことを特徴とする。 The invention according to claim 1 comprises a substantially hemispherical helmet body that covers the head, and a rectifying member that extends rearward from the helmet body and is locked to the helmet body so as to swing up and down.

請求項２に係る発明は、整流部材の後端から、ゴム紐などの弾性線部材を延ばし、この弾性線部材の先端にフックを設け、このフックを乗員のベルト又は衣服に引っかけることができるようにしたことを特徴とする。 According to the second aspect of the present invention, an elastic wire member such as a rubber string is extended from the rear end of the rectifying member, a hook is provided at the tip of the elastic wire member, and the hook can be hooked on the belt or clothes of the occupant. It is characterized by that.

請求項３に係る発明は、ヘルメット本体の後端と整流部材の裏面とを、ばね部材で連結し、整流部材に常に下向きの力を付与するようにしたことを特徴とする。 The invention according to claim 3 is characterized in that the rear end of the helmet body and the back surface of the rectifying member are connected by a spring member so that a downward force is always applied to the rectifying member.

請求項１に係る発明では、整流部材を上下スイング可能にしたので、整流部材を最も走行抵抗の少ない向きにすることができるという利点がある。 In the invention which concerns on Claim 1, since the baffle member was made to be able to swing up and down, there exists an advantage that a baffle member can be made the direction with the least running resistance.

請求項２に係る発明では、整流部材の後端をゴム紐などを介してベルトなどに引っかけることができるようにした。ゴム紐で引かれることで、整流部材は常に乗員の肩若しくは背中に載る。この結果、ヘルメット本体と整流部材と背中とが連続し、好ましい流線形状を創り出すことができる。 In the invention according to claim 2, the rear end of the flow regulating member can be hooked on a belt or the like via a rubber cord or the like. The straightening member is always placed on the shoulder or back of the occupant by being pulled by the rubber string. As a result, the helmet body, the rectifying member, and the back are continuous, and a preferable streamline shape can be created.

請求項３に係る発明は、ヘルメット本体の後端と整流部材の裏面とをばね部材で連結し、整流部材に常に下向きの力を付与するようにしたので、頭を上下させても、整流部材を常に好ましい姿勢に保持することができ、好適な整流効果を発揮させることができる。 In the invention according to claim 3, the rear end of the helmet body and the back surface of the rectifying member are connected by a spring member so that a downward force is always applied to the rectifying member.
