発明の分野
本発明は、バーハンドルを覆う合成樹脂製のハンドルカバーに、前照灯が光軸調節を可能として取付けられるとともに前照灯の左右に配置される一対の方向指示灯が取付けられる自動二輪車に関し、特に、前照灯の支持構造の改良に関する。
背景技術
バーハンドルを下方から覆う合成樹脂製の下部カバーと、バーハンドルを上方から覆う合成樹脂製の上部カバーとで構成されるハンドルカバーに、前照灯が光軸調節を可能として取付けられるとともに左右一対の方向指示灯が取付けられる構造が、日本特許第２７６７２４０号公報で開示されており、このものでは、下部カバーに一体に設けられた板状の支持部の上端に、前照灯が左右に備える支軸を下方から支持する軸受部が上方に開いた略Ｕ字状にして設けられ、前照灯の下部に突設された突起が前後位置を調節可能として下部カバーに締結されている。
ところで、ハンドルカバーが、バーハンドルを前方側から覆う合成樹脂製の前部カバーと、バーハンドルを後方側から覆う合成樹脂製の後部カバーとで構成され、前部カバーに、前照灯が光軸調節を可能として取付けられるとともに、左右一対の方向指示灯が取付けられる場合があり、この場合、上記従来のような前照灯の支持構造を採用すると、合成樹脂により型成形される前部および後部カバーの型割り方向と、前照灯が左右に備える支軸を下方から支持する軸受部を形成するための型の移動方向とが直交することになり、スライド型を用いざるを得ないのでハンドルカバーの製造コストが高くなる。そこでスライド型を用いずに、前照灯を支持する構造を実現することが要求されるが、その際、ハンドルカバーの形状が複雑化することは避けたい。
本発明は、かかる事情に鑑みてなされたものであり、前部および後部カバーでハンドルカバーを構成するようにした自動二輪車において、前部および後部カバーの成形時にスライド型を用いることを回避するとともに各カバーの形状を単純化することを可能とした上で、前照灯を揺動可能に支持し得るようにした前照灯支持構造を提供することを目的とする。
発明の開示
上記目的を達成するために、本発明は、バーハンドルを覆うハンドルカバーが、バーハンドルを前方側から覆う合成樹脂製の前部カバーと、バーハンドルを後方側から覆う合成樹脂製の後部カバーとで構成され、前部カバーに、前照灯が光軸調節を可能として取付けられるとともに、前照灯の左右に配置される一対の方向指示灯が取付けられる自動二輪車において、前部および後部カバーの一方に設けられた一対の第１軸受半部と、前記両方向指示灯に設けられた一対の第２軸受半部とで前後から挟まれて揺動可能に支持される一対の支軸が、前照灯の左右両側に同軸に突設されることを第１の特徴とする。
このような構成によれば、前照灯が左右両側に同軸に備える一対の支軸が、それぞれ一対ずつの第１軸受半部および第２軸受半部で前後から挟まれるようにして揺動可能に支持されることになり、前部および後部カバーの一方に設けられる第１軸受半部は、前部および後部カバーの型成形時の型割り方向と同方向で型成形されればよいのでスライド型が不要であり、ハンドルカバーの製造コストを低減することができ、しかも第１軸受半部は、前記型割り方向の一方に臨む単純な形状であればよいので、前部および後部カバーの形状も単純化することができる。
また本発明は、上記第１の特徴の構成に加えて、前記各方向指示灯の上部に、それらの方向指示灯を前部カバーに取付けるための取付け部と、該取付け部に隣接した前記第２軸受半部とが、相互に連なって突設されることを第２の特徴とし、かかる構成によれば、前照灯の支軸の半部を支持する第２軸受半部の近傍で方向指示灯が前部カバーに取付けられるので、第２軸受半部による支軸の支持剛性を高めることができる。

両リヤサイドカバー３１…の上部間には、収納ボックス２４および燃料タンク２３を上方から覆うタンデムシート３２が、収納ボックス２４への物品の収納および取出しを可能とすべく開閉可能に配置される。
図２および図３を併せて参照して、左右両端にグリップ３４，３５を備えるバーハンドル１５の右端部には、グリップ３５を握った手で操作可能なレバー３７が設けられており、このバーハンドル１５の中央部は、前記グリップ３４を左側から突出させるとともに前記グリップ３５およびレバー３７を右側から突出させるようにしてハンドルカバー３８で覆われる。
このハンドルカバー３８は、バーハンドル１５を前方側から覆う合成樹脂製の前部カバー３９と、バーハンドル１５を後方側から覆う合成樹脂製の後部カバー４０とが相互に締結されて成るものであり、後部カバー４０がバーハンドル１５に取付けられる。
ハンドルカバー３８における後部カバー４０の上部中央には、メータユニット４１が取付けられる。またバーハンドル１５には、前部カバー３９の左右両側を貫通する支持アーム４２，４２が取付けられており、タンデムシート３２上のドライバが後方を視認するためのバックミラー４３，４３が前記支持アーム４２，４２の上端に取付けられる。
前部カバー３９には、その前面中央部に配置される開口部４４と、該開口部４４の左右両側に配置される開口部４５，４５とが設けられており、開口部４４には配置される前照灯４６は、開口部４５，４５にそれじれ配置されて前部カバー３９に取付けられる方向指示灯４７，４７および前部カバー３９により、上下方向での照射方向の調節すなわち光軸調節を可能として支持される。
図４〜図６において、前照灯４６は、内面を反射鏡として前方を開いた椀状に形成される合成樹脂製の灯体４８と、灯体４８内の中央部に保持されるバルブ４９と、灯体４８の前端開口部を覆う前面レンズ５０とで構成される。しかも該前照灯４６における灯体４８の左右両側には、支軸５１…が同軸に突設される。
方向指示灯４７は、内面を反射鏡として前方を開いた椀状に形成される合成樹脂製の灯体５２と、灯体５２内の中央部に保持されるバルブ５３と、灯体５２の前端開口部を覆う前面レンズ５４とで構成される。この方向指示灯４７における灯体５２には、その周方向に間隔をあけた複数箇所たとえば３箇所に取付け部５５，５６，５７が突設されており、それらの取付け部５５，５６，５７が、ねじ部材５８…により前部カバー３９に締結される。
前記両支軸５１…は、該支軸５１…の前半部を支持するようにして前部カバー３９に一体に設けられた一対の第１軸受半部５９…と、各方向指示灯４７…の灯体５２に一体に設けられて前記支軸５１…の後半部を支持する一対の第２軸受半部６０…とで揺動可能に支持される。
しかも第２軸受半部６０は、方向指示灯４７を前部カバー３９に取付けるために該方向指示灯４７の灯体５２に設けられている取付け部５５，５６，５７のうち灯体５２の上部に設けられている取付け部５５に隣接した位置で、該取付け部５５と相互に連なるようにして前記灯体５２に突設されている。

而してねじ部材６４を緩めることで、ナット６２は長孔６３の長手方向任意の位置に移動可能であり、このボス６２の移動により、前照灯４６がその支軸５１…の軸線まわりに揺動し、前記ねじ部材６４を締付けることで前照灯４６の揺動姿勢すなわち前照灯４６の光軸を一定に保持することができる。しかもねじ部材６４の操作を可能とするために、前部カバー３９の下部外面には前記ねじ部材６４の頭部を臨ませる凹部６５が前方および下方に開くようにして形成される。
次にこの実施例の作用について説明すると、前照灯４６がその両側に同軸に備える一対の支軸５１…は、該支軸５１…の前半部を支持するようにして前部カバー３９に一体に設けられた一対の第１軸受半部５９…と、前部カバー３９に取付けられる各方向指示灯４７…の灯体５２に一体に設けられて前記支軸５１…の後半部を支持する一対の第２軸受半部６０…とで揺動可能に支持される。
すなわち、支軸５１…は、一対ずつの第１軸受半部５９…および第２軸受半部６０…で前後から挟まれるようにして揺動可能に支持されることになり、前部カバー３９に設けられる第１軸受半部５９…は、前部カバー３９の型成形時の型割り方向と同方向で型成形されればよいのでスライド型が不要であり、したがってハンドルカバー３８の製造コストを低減することができる。しかも第１軸受半部５９…は、前記型割り方向の一方に臨む単純な形状であればよいので、前部および後部カバー３９，４０の形状も単純化することができる。
また各方向指示灯４７…の上部には、それらの方向指示灯４７…を前部カバー３９に取付けるための取付け部５５…と、該取付け部５５…に隣接した第２軸受半部６０…とが、相互に連なって突設されるので、前照灯４６の支軸５１…の後ろ半部を支持する第２軸受半部６０…の近傍で方向指示灯４６…が前部カバー３９に取付けられることになり、第２軸受半部６０…による支軸５１…の支持剛性を高めることができる。
以上、本発明の実施例を説明したが、本発明は上記実施例に限定されるものではなく、特許請求の範囲に記載された本発明を逸脱することなく種々の設計変更を行うことが可能である。
たとえば上記実施例では、支軸５１の前半部を支持する第１軸受半部５９が前部カバー３９に設けられたが、支軸５１の後半部を支持する第１軸受半部が後部カバーに設けられ、前部カバーに取付けられる方向指示灯に、支軸５１の前半部を支持する第２軸受半部が設けられるようにしてもよい。FIELD OF THE INVENTION The present invention relates to an automatic steering system in which a headlight is mounted on a synthetic resin handle cover that covers a bar handle so that an optical axis can be adjusted, and a pair of direction indicators arranged on the left and right sides of the headlight are mounted. The present invention relates to a motorcycle, and more particularly to an improvement in a headlight support structure.
BACKGROUND ART A headlight is attached to a handle cover composed of a synthetic resin lower cover that covers a bar handle from below and a synthetic resin upper cover that covers a bar handle from above so that the optical axis can be adjusted. Japanese Patent No. 2767240 discloses a structure in which a pair of left and right direction indicators are mounted. In this structure, headlights are provided on the upper end of a plate-shaped support unit integrally provided on a lower cover. A bearing portion for supporting a support shaft provided from below is provided in a substantially U-shape which is opened upward, and a protrusion protruding from a lower portion of the headlight is fastened to a lower cover so that a front-rear position can be adjusted. .
By the way, the handle cover is composed of a synthetic resin front cover that covers the bar handle from the front side, and a synthetic resin rear cover that covers the bar handle from the rear side. Axial adjustment is possible, and a pair of left and right direction indicators may be installed.In this case, if a conventional headlamp support structure as described above is adopted, the front part and the front part which are molded from synthetic resin are used. Since the mold direction of the rear cover and the moving direction of the mold for forming the bearing for supporting the support shafts provided on the left and right of the headlight from below will be orthogonal to each other, the slide mold must be used. The manufacturing cost of the handle cover increases. Therefore, it is required to realize a structure for supporting the headlight without using a slide type. At this time, it is desired to avoid a complicated shape of the handle cover.
The present invention has been made in view of such circumstances, and in a motorcycle in which a front and rear cover constitutes a handle cover, it is possible to avoid using a slide mold when molding the front and rear covers. It is an object of the present invention to provide a headlight supporting structure capable of simplifying the shape of each cover and swingably supporting a headlight.
DISCLOSURE OF THE INVENTION To achieve the above object, the present invention provides a handle cover for covering a bar handle, a front cover made of synthetic resin for covering the bar handle from the front side, and a synthetic resin cover for covering the bar handle from the rear side. The motorcycle includes a rear cover, a headlight is mounted on the front cover so that the optical axis can be adjusted, and a pair of direction indicators arranged on the left and right of the headlight is mounted. A pair of pivots that are supported from the front and rear between a pair of first bearing halves provided on one side of the rear cover and a pair of second bearing halves provided on the two-way indicator lamp so as to be swingable. However, a first feature is that the headlights are provided coaxially on both left and right sides of the headlight.
According to such a configuration, a pair of support shafts coaxially provided on the left and right sides of the headlamp can swing so as to be sandwiched between the pair of first and second bearing halves from the front and rear. And the first bearing half provided on one of the front and rear covers only needs to be molded in the same direction as the mold split direction at the time of molding the front and rear covers. Since no mold is required, the manufacturing cost of the handle cover can be reduced, and the first bearing half has only to have a simple shape facing one of the mold split directions. Can also be simplified.
Further, in addition to the configuration of the first feature, the present invention further includes a mounting portion for mounting the directional indicators on the front cover, on the upper portion of each of the directional indicators, and a mounting portion adjacent to the mounting portion. The second feature is that the two bearing halves are projectingly connected to each other, and according to such a configuration, the direction near the second bearing half supporting the half of the support shaft of the headlight is provided. Since the indicator light is attached to the front cover, the support rigidity of the support shaft by the second bearing half can be increased.
