Abstract
Description
この構成によれば、導風部が前面視で連通孔を覆うことで、車両前方に向けた開口を有しない。そのため、導風部により、走行中の風、水、泥、砂、木枝などからライダーのナックル部、腕部を保護することができる。したがって、走行中の防風・防泥・防砂利・防木枝効果が損なわれることを抑制することができる。加えて、車両のハンドルのグリップの前方に配置され、上下方向に開口する連通孔を有する導風部を備えることで、連通孔により、ナックルガードの後方の負圧を補正することができる。そのため、より小さい前面投影面積でより大きい防風効果を得ることができる。加えて、連通孔は前面視で見えないため、ナックルガードの一体感を創出し、意匠性に優れる。
この構成によれば、ナックルガードを分割構造とし、分割部品(第一保護部材および第二保護部材)の積層部で連通孔を形成するため、ナックルガードが複雑な構造となることを抑制し、かつ、ナックルガードの成形が容易となる。
この構成によれば、第二保護部材を車幅方向内側へ撓ませ、第一保護部材の取付孔の車幅方向内側で固定することにより、積層部の連通孔(隙間)を拡大することで、ナックルガードの後方へ向かう風量(ナックルガードの後方の負圧を補正するための風量)を調整することができる。そのため、走行速度、気温(手元雰囲気温度含む。)等の走行条件等を加味して、ライダーの好みに応じて、ナックルガードの後方の負圧を調整しやすい。
この構成によれば、第一保護部材と第二保護部材との相対位置を規定することができる。
この構成によれば、第二保護部材の初期状態および湾曲状態のそれぞれにおいて、第一保護部材と第二保護部材との相対位置を規定することができる。
この構成によれば、第二保護部材を第一保護部材から取り外すことにより、第一保護部材のみで使用することができる。例えば、長距離走行時、オフロード走行時には、第二保護部材を第一保護部材に取り付けて走行する。例えば、低速走行時、市街地などのオンロード走行時には、第一保護部材のみで走行する。例えば、気温の高低で、気温が低いときには、第二保護部材を第一保護部材に取り付けて走行する。例えば、気温が高いときには、第一保護部材のみで走行する。このように条件に応じて、ナックルガードの仕様を変更可能なので、仕様変更の自由度が向上する。加えて、ナックルガードの全部を別部品に交換することなく、一部のみ部品を追加することで仕様変更が可能なので、部品コストが低減する。加えて、第一保護部材が第二保護部材を取り付けるための取付孔を有する場合、取付孔を導風孔として機能させることができる。
図1は、鞍乗型車両の一例として、自動二輪車1を示す。図1を参照し、自動二輪車1は、車体前後方向略中央にエンジン2を搭載する。以下、自動二輪車を単に「車両」ということがある。
図5に示すように、ナックルガード30は、グリップ17とハンドル15とに跨るように、グリップ17の前方に配置されている。例えば、ナックルガード30は樹脂製である。ナックルガード30は、乗員がグリップ17を把持した際に乗員の手の前方を覆う。上面視で、ナックルガード30は、後方に開放するU字状を有する。
上面視で、第一保護部材31は、後方に開放するU字状を有する(図9参照)。図4に示すように、第一保護部材31は、グリップ17の前方に配置されたガード部材39と、ガード部材39とレバーホルダ20とを連結する連結部材50と、を備える。
第一延在部41の車幅方向外側部(第二延在部42との隣接部分)には、連結部材50の前壁部53の凹部53aに係合可能な係合凸部47が設けられている(図9参照)。係合凸部47は、第一延在部41の車幅方向外側部の後面から後方に突出している(図7参照)。
下壁部52は、クラッチレバー19の下方に配置されている。下壁部52は、前後方向に延在する板状を有する。
前壁部53は、クラッチレバー19の前方に配置されている。前壁部53は、上壁部51の前端と下壁部52の前端とを連結する。上面視で、前壁部53は、前方保護部40の第一延在部41に沿うように、前壁部53の車幅方向内端が後方に位置し、かつ、前壁部53の車幅方向外端が前方に位置するように傾斜している(図9参照)。前壁部53には、車幅方向外方に開放する凹部53aが設けられている。
図2に示すように、第二保護部材32は、第一保護部材31の前方保護部40よりも大きい外形を有する。第二保護部材32は、前方保護部40に沿うように車幅方向に延在している。第二保護部材32の上端は、第一保護部材31の上端よりも上方に位置する。第二保護部材32の上縁は、上方に凸の湾曲形状を有する。第二保護部材32の下端は、前方保護部40の下端よりも上方に位置する。第二保護部材32の下縁は、前方保護部40の前縁に沿う外形を有する。断面視で、第二保護部材32の前面は、第二保護部材32の上端が後方に位置し、かつ、第二保護部材32の下端が前方に位置するように傾斜している(図6参照)。
第二保護部材32の車幅方向内側部は、ボルト等の締結部材29により第一保護部材31の第一延在部41に取り付けられている。第二保護部材32は、第一保護部材31と共に、連結部材50から離脱可能に連結部材50に取り付けられている。
図7に示すように、第一保護部材31と第二保護部材32とは、保護部材同士が重なる積層部37を形成する。連通孔36は、積層部37を上下方向に開放している。積層部37は、前面視で第一保護部材31における前方保護部40と第二保護部材32の下部とが重なる部分である(図2参照)。連通孔36は、前方保護部40の前面と第二保護部材32の下部後面との間の隙間である。断面視で、連通孔36は、開口上端が後方に位置し、かつ、開口下端が前方に位置するように傾斜している。
図15を参照し、実施形態に係るナックルガード30の作用を比較例とともに説明する。
比較例は、実施形態に係る連通孔36を有しない。または、比較例は、連通孔36の開口下端が閉塞されている。図中矢印Wxは比較例の走行風の流れ、矢印W1,W2は実施形態の走行風の流れをそれぞれ示す。
図16、図17を参照し、実施形態に係る第二保護部材32の作用について説明する。
第二保護部材32は、第一保護部材31における取付孔44aに沿って車幅方向内側へ撓むことにより、連通孔36を拡大することが可能である。
本実施形態によれば、導風部35が前面視で連通孔36を覆うことで、車両前方に向けた開口を有しない。そのため、導風部35により、走行中の風、水、泥、砂、木枝などからライダーのナックル部、腕部を保護することができる。したがって、走行中の防風・防泥・防砂利・防木枝効果が損なわれることを抑制することができる。加えて、車両のハンドル15のグリップ17の前方に配置され、上下方向に開口する連通孔36を有する導風部35を備えることで、連通孔36により、ナックルガード30の後方の負圧を補正することができる。そのため、より小さい前面投影面積でより大きい防風効果を得ることができる。加えて、連通孔36は前面視で見えないため、ナックルガード30の一体感を創出し、意匠性に優れる。
この構成によれば、ナックルガード30を分割構造とし、分割部品(第一保護部材31および第二保護部材32)の積層部37で連通孔36を形成するため、ナックルガード30が複雑な構造となることを抑制し、かつ、ナックルガード30の成形が容易となる。
この構成によれば、第二保護部材32を車幅方向内側へ撓ませ、第一保護部材31の取付孔44aの車幅方向内側で固定することにより、積層部37の連通孔36(隙間)を拡大することで、ナックルガード30の後方へ向かう風量(ナックルガード30の後方の負圧を補正するための風量)を調整することができる。そのため、走行速度、気温(手元雰囲気温度を含む。)等の走行条件等を加味して、ライダーの好みに応じて、ナックルガード30の後方の負圧を調整しやすい。
この構成によれば、第一保護部材31と第二保護部材32との相対位置を規定することができる。
この構成によれば、第二保護部材32の初期状態および湾曲状態のそれぞれにおいて、第一保護部材31と第二保護部材32との相対位置を規定することができる。
この構成によれば、第二保護部材32を第一保護部材31から取り外すことにより、第一保護部材31のみで使用することができる。例えば、長距離走行時、オフロード走行時には、第二保護部材32を第一保護部材31に取り付けて走行する。例えば、低速走行時、市街地などのオンロード走行時には、第一保護部材31のみで走行する。例えば、気温の高低で、気温が低いときには、第二保護部材32を第一保護部材31に取り付けて走行する。例えば、気温が高いときには、第一保護部材31のみで走行する。このように条件に応じて、ナックルガード30の仕様を変更可能なので、仕様変更の自由度が向上する。加えて、ナックルガード30の全部を別部品に交換することなく、一部のみ部品を追加することで仕様変更が可能なので、部品コストが低減する。加えて、第一保護部材31が第二保護部材32を取り付けるための取付孔44aを有する場合、取付孔44aを導風孔として機能させることができる。
上記実施形態では、連通孔36は、前面視で第一保護部材31と第二保護部材32とが重なる積層部37の全部を上下方向に開放している例を挙げて説明したが、これに限らない。例えば、連通孔36は、積層部37の一部を上下方向に開放していてもよい。連通孔36は、積層部37の少なくとも一部を上下方向に開放していてもよい。
そして、上記実施形態における構成は本発明の一例であり、実施形態の構成要素を周知の構成要素に置き換える等、本発明の要旨を逸脱しない範囲で種々の変更が可能である。
