自動車用の前照灯は、上向き過ぎであると対向車に眩惑を与えるので危険であ る。そうかと言って下向き過ぎであると走行方向前方の路上が旨く照明されない ので運転し難い。そこで自動車用前照灯は、これを車体に装着した状態で、その 光軸を若干上向き・下向きに調節する装置を設ける必要が有る。 前照灯は一般にランプハウジング内に凹面反射鏡を設けるとともに、該凹面反 射鏡の焦点付近に光源バルブを位置せしめた構造であり、前照灯の光軸とは前記 凹面反射鏡の対称軸の意である。従って、光軸を調整するには、 （イ）ランプハウジングと凹面反射鏡との関係位置を一定に保った侭で、該ラン プハウジングを上下に傾動させるか、 （ロ）ランプハウジングを車体に取り付けた侭で動かさず、凹面反射鏡を上下に 傾動させるか、 二つの方法が有る。 図６はランプハウジングを傾動させる方式の光軸調整装置の従来例を示す。 図７は凹面反射鏡を上下に傾動せしめる方式の光軸調整装置の従来例を示す。 （図６参照）１はランプハウジングで、その内面１ａは凹面反射鏡になってい る。Ｚ−Ｚは光軸、Ｆは焦点である。該焦点Ｆの近傍に光源バルブ２が設けられ る。３は前面レンズである。 Headlights for automobiles are dangerous because they dazzle oncoming vehicles if they are facing upwards too much. On the other hand, if it is facing down too much, the road ahead in the direction of travel will not be illuminated well and it will be difficult to drive. Therefore, it is necessary to provide a vehicle headlamp with a device for adjusting the optical axis of the vehicle headlamp slightly upward and downward with the headlamp mounted on the vehicle body. A headlamp generally has a structure in which a concave reflecting mirror is provided in the lamp housing and a light source bulb is located near the focal point of the concave reflecting mirror. The optical axis of the headlamp is the symmetry axis of the concave reflecting mirror. It means Therefore, in order to adjust the optical axis, (a) tilt the lamp housing up and down while keeping the relative position of the lamp housing and the concave reflecting mirror constant, or (b) mount the lamp housing on the vehicle body. There are two methods of tilting the concave reflecting mirror up and down without moving it with the attached windshield. FIG. 6 shows a conventional example of an optical axis adjusting device in which the lamp housing is tilted. FIG. 7 shows a conventional example of an optical axis adjusting device of a type in which a concave reflecting mirror is tilted up and down. (See FIG. 6) Reference numeral 1 denotes a lamp housing, the inner surface 1a of which is a concave reflecting mirror. ZZ is the optical axis and F is the focus. A light source bulb 2 is provided near the focal point F. 3 is a front lens.
【０００３】 前記ランプハウジング１を球継手４によって傾動自在に支承するとともに、該 ランプハウジング１にナット部材５を取り付け、これに螺合した雄ネジ部材６に よって上記ナット部材を光軸Ｚ−Ｚと略平行にネジ送り出来るように構成される 。これにより、上記雄ネジ部材６を回すと光軸Ｚ−Ｚが、前上がり（図において 左上がり），前下がり（左下がり）に往復傾動せしめられる。 （図７参照）ランプハウジング１′は車体に固定される。 上記ランプハウジング１′に対して、球継手４′を介して凹面反射鏡７が傾動 自在に支承されている。上記凹面反射鏡７に球継手８を介して、駆動ユニットの 駆動杆９ａが取り付けられている。 上記駆動ユニット９がリモートコントロールされて駆動杆９ａが図の左右方向 に前後進すると、凹面反射鏡７は球継手４′の回りに傾動せしめられ、光軸が調 整される。The lamp housing 1 is tiltably supported by a ball joint 4, a nut member 5 is attached to the lamp housing 1, and a male screw member 6 screwed to the nut member 5 is used to attach the nut member to the optical axis ZZ. It is configured so that the screw can be fed substantially parallel to. Accordingly, when the male screw member 6 is rotated, the optical axis ZZ is reciprocally tilted forward (upward left in the drawing) and downward (downward left). The lamp housing 1'is fixed to the vehicle body (see FIG. 7). A concave reflecting mirror 7 is tiltably supported on the lamp housing 1'via a ball joint 4 '. A drive rod 9a of a drive unit is attached to the concave reflecting mirror 7 via a ball joint 8. When the drive unit 9 is remotely controlled and the drive rod 9a moves forward and backward in the left-right direction in the figure, the concave reflecting mirror 7 is tilted around the ball joint 4 ', and the optical axis is adjusted.

A spherical member 9a 1 is fixed to the tip of the drive rod 9a, and the member 10 having a spherical seat 10a is fitted into the spherical member 9a 1 to form a ball joint 8.

図７に示した従来例の場合、球面座１０ａを有する部材１０は、その球面座に 球状部材９ａ1を挟み込んだ形で凹面反射鏡７の孔に圧入されている。このため 駆動杆９ａが図の右方に動くとき、該球状部材９ａ1と球面座を有する部材１０ とが抜け出して外れてしまうおそれが有る。こうした問題点は、ランプハウジン グを傾動させる方式の光軸調整装置（ユニット可動形）においても、凹面反射鏡 を傾動させる方式の光軸調整装置（リフレクタ可動形）においても生じる。また 電動式の駆動ユニットを用いて光軸方向を調整する方式の装置においても、手動 操作によって光軸方向を調整する方式の装置においても発生し得る。 本考案は上述の事情に鑑みて為されたものであって、ユニット可動形であると リフレクタ可動形であるとを問わず、また電動操作式であるか手動操作式である かに拘らず、傾動操作力を受ける球面座を有する部材と、傾動操作力を与える駆 動杆に固着された球状部材とを嵌合せしめてなる球継手を有する光軸調整装置を 適用の対象とし、上記の球面座を有する部材と駆動杆に固着された球状部材との 嵌合が離脱するおそれの無いように改良した車両用灯具の光軸調整装置を提供す ることを目的とする。単に離脱するおそれの無い球継手を構成するだけであって 装置の大形・大重量化，コスト上昇および組立所要工数の増加を認容するのであ れば、従来技術によって離脱しない球継手を構成することは可能であるが、本考 案は車両用灯具の光軸調整装置に普遍的に適用可能で、構造が簡単で、小形・軽 量に構成することができ、組立所要工数が少なく、しかも離脱するおそれの無い 球継手を備えた車両用灯具の光軸調整装置を提供しようとするものである。The conventional example shown in FIG. 7, member 10 having a spherical seat 10a is press-fitted into the hole of the concave reflecting mirror 7 in sandwiched form spherical member 9a 1 in its spherical seat. Therefore, when the drive rod 9a moves to the right in the figure, there is a risk that the spherical member 9a 1 and the member 10 having a spherical seat will come out and come off. These problems occur both in the optical axis adjusting device that tilts the lamp housing (unit movable type) and in the optical axis adjusting device that tilts the concave reflecting mirror (movable reflector type). Further, it may occur in an apparatus that adjusts the optical axis direction by using an electric drive unit or in an apparatus that adjusts the optical axis direction by a manual operation. The present invention has been made in view of the above circumstances, regardless of whether it is a unit movable type or a reflector movable type, regardless of whether it is an electric operation type or a manual operation type, The optical axis adjusting device having a ball joint formed by fitting a member having a spherical seat that receives the tilting operation force and a spherical member that is fixed to the driving rod that gives the tilting operation force is applied to the above-mentioned spherical seat. An object of the present invention is to provide an optical axis adjusting device for a vehicular lamp which is improved so that there is no risk of the fitting between the member having the above and the spherical member fixed to the drive rod being separated. If only forming a ball joint that is not likely to come off and permitting larger and heavier equipment, higher costs, and increased man-hours required for assembly, a ball joint that does not come off is constructed by conventional technology. However, this idea is universally applicable to the optical axis adjustment device for vehicle lamps, has a simple structure, can be constructed in a compact and lightweight manner, and requires a small number of assembly steps. It is an object of the present invention to provide an optical axis adjusting device for a vehicular lamp including a ball joint that does not come off.

上記の目的を達成するために創作した本考案の基本的原理を略述すると、 球状部材を固着した駆動杆と、球面座を有する部材との抜け止め手段として 、プッシュナットを利用する。プッシュナットはメネジを有せず、バネ鋼板をプ レス加工して構成されたもので、中心孔に向けて切り起こされた複数の板バネ状 舌片を有していて、該中心孔に挿通された軸の表面に上記舌片の先端が食い込ん で抜け止めの作用をし、相手の軸がオネジであればナットに類似した作用もする 公知の部材である。上記のプッシュナットを予め球面座を有する部材の中に収納 しておけば、杆状の部材をワンタッチで挿通することができる。上記の杆状部材 に抜け止め用の段付部を設けておけば、抜け止め機能はいっそう確実となる。 上述の原理に基づく具体的構成として本考案は、ランプハウジング内に凹面反 射鏡を設けると共に、該反射鏡の焦点付近に光源バルブを位置せしめた車両用灯 具におけるランプハウジング及び反射鏡の少なくとも何れか一方を車両の固定部 材に対して傾動自在に支承すると共に、該何れか一方に球面座を有する部材を取 りつけ、かつ、駆動杆に固定した球状部材を上記球面座に嵌合した構造の光軸調 整装置において、 前記球状部材は前記駆動杆の先端近傍に、該先端から離間せしめて固定され、 上記駆動杆の、球状部材よりも先端の部分にプッシュナットが嵌め合わされ、 上記駆動杆の先端に、上記プッシュナットの抜け止め用の段付部が設けられ、 かつ、上記プッシュナットは、前記球面座を有する部材の中に収納されている ことを特徴とする。 The basic principle of the present invention, which was created to achieve the above object, will be briefly described. A push nut is used as a means for preventing the driving rod to which a spherical member is fixed and the member having a spherical seat from coming off. The push nut does not have a female screw and is made by pressing a spring steel plate.It has a plurality of leaf spring tongues cut and raised toward the center hole and is inserted into the center hole. It is a known member that the tip of the tongue piece bites into the surface of the formed shaft to prevent the shaft from coming off, and also has a function similar to that of a nut if the shaft of the other side is a male screw. If the push nut is stored in advance in a member having a spherical seat, a rod-shaped member can be inserted with one touch. If the rod-shaped member is provided with a stepped portion for retaining, the retaining function becomes more reliable. As a concrete configuration based on the above principle, the present invention provides at least a lamp housing and a reflecting mirror in a vehicle lamp in which a concave reflecting mirror is provided in the lamp housing and a light source bulb is positioned near the focal point of the reflecting mirror. One of the bearings is supported so that it can be tilted with respect to the fixed part of the vehicle, a member having a spherical seat is attached to one of the fixed parts, and a spherical member fixed to the drive rod is fitted to the spherical seat. In the optical axis adjusting device having the structure described above, the spherical member is fixed in the vicinity of the tip of the drive rod so as to be separated from the tip, and a push nut is fitted to a portion of the drive rod that is closer to the tip than the spherical member, A stepped portion for preventing the push nut from coming off is provided at the tip of the drive rod, and the push nut is housed in a member having the spherical seat. Characterize.

上記の構成によれば、駆動杆の最先端から若干後退した位置に球状部材が固着 されているので、該駆動杆の最先端付近は上記球状部材よりも若干突出している 。この突出部がプッシュナットに挿通されると、該プッシュナットが容易には抜 けなくなる。そして、このプッシュナットは球面座を有する部材の中に収納され ているので、上記球面座を有する部材と駆動杆とは離脱するおそれが無い。 According to the above configuration, since the spherical member is fixed at a position slightly retracted from the tip of the drive rod, the vicinity of the tip of the drive rod is slightly projected from the spherical member. When the protruding portion is inserted into the push nut, the push nut cannot be easily removed. Further, since the push nut is housed in the member having the spherical seat, there is no possibility that the member having the spherical seat and the driving rod are separated from each other.

図２は本考案に係る車両用灯具の光軸調整装置の１実施例を示す断面図である 。１′はランプハウジングであり、その中にリフレクタ７が傾動可能に支承され ている。該リフレクタ７の前面（図において左側面）は凹面反射鏡７ａになって おり、背面（図において左側面）にブラケット７ｂが一体成形されている。この ブラケット７ｂに対して、球面座１１ａを形成された合成樹脂製の球面座部材１ １が取り付けられている。上記球面座部材１１の取付構造については図１を参照 して後述する。９は駆動ユニット，９ａは駆動杆である。本例の駆動杆９ａは、 その先端（図において左端）に半球面状部を有する頭部９ａ2が一体成形されて おり、この頭部から若干離間して球状部材９ａ1が一体成形されている。 上記の球状部材９ａ1は前記球面座１１ａと回動自在に嵌合して球継手を構成 している。前記の駆動杆９ａの先端部付近は球状部材９ａ1よりも前方（図にお いて左方）に突出して、球状部材９ａ1と頭部９ａ2とを接続する突出杆状部９ａ 4 となっている。一方、前記球面状部材１１内には予めプッシュナット１２が収 納されており、前記の頭部９ａ2および突出杆状部９ａ4を突き通されて、駆動杆 ９ａが図の左側に抜け出さないよう、抜け止め機能を果たしている。 2 is a sectional view showing an embodiment of an optical axis adjusting device for a vehicle lamp according to the present invention. Reference numeral 1'denotes a lamp housing in which a reflector 7 is tiltably supported. A front surface (left side surface in the figure) of the reflector 7 is a concave reflecting mirror 7a, and a bracket 7b is integrally formed on a rear surface (left side surface in the figure). A synthetic resin spherical seat member 11 having a spherical seat 11a is attached to the bracket 7b. The mounting structure of the spherical seat member 11 will be described later with reference to FIG. Reference numeral 9 is a drive unit, and 9a is a drive rod. The drive rod 9a of this example has a head 9a having a hemispherical portion at its tip (left end in the figure).2Is integrally molded, and the spherical member 9a is slightly separated from the head.1Are integrally molded. Above spherical member 9a1Is rotatably fitted to the spherical seat 11a to form a ball joint. The vicinity of the tip of the drive rod 9a is a spherical member 9a.1To the front (left side in the figure) of the spherical member 9a1And head 9a2Projecting rod 9a for connecting with Four Has become. On the other hand, the push nut 12 is previously housed in the spherical member 11, and the head 9a.2And protruding rod-shaped portion 9aFourThe drive rod 9a functions to prevent the drive rod 9a from coming out to the left side in the drawing by being pushed through.
【０００９】 上記の図２は、駆動杆９ａの軸心を通る垂直面による断面図である。該駆動杆 ９ａの軸心を通る水平面による断面を模式的に描いて図１に示す。本図１は構成 の理解に便なるごとく模式化してあるので、ハッチングの付し方や部材の縦横寸 法比など、厳密にはＪＩＳの製図法に従っていない。 球面座部材１１の外側面には１対の取付用溝１１ｂが設けられている。これに 対応して、リフレクタのブラケット７ｂの内側には１対の突条７ｃが一体成形さ れていて、前記の溝１１ｂに嵌合し、球面座部材１１を固定的に保持している。 上記球面座部材１１の３面図を図３に示す。前記の取付用の溝１１ｂは（Ａ）図 では隠れ線で表わされ、（Ｂ）図では実線で表わされ、（Ｃ）図では輪郭に現わ れている。上記図３のＡ−Ａ断面を図４（Ａ）に、Ｂ−Ｂ断面を図４（Ｂ）に、 それぞれ示す。前記の溝１１ｂは本図４（Ｂ）の輪郭に現われている。 図３および図４に示した１１ｃは前述（図２）のプッシュナットを収納するた めに空隙である。本実施例においては、別体に構成されたプッシュナットを球面 座部材１１の空隙１１ｃ内へ容易に挿入できるよう、該空隙１１ｃをトンネル状 に構成してある。すなわち、図４（Ｂ）は該トンネル状の空隙１１ｃを縦断した 形の断面図であってプッシュナットは矢印ｉ方向に挿入される。また図４（Ａ） は該トンネル状の空隙１１ｃを横断した形の断面図であってプッシュナットは紙 面と交わる方向に挿入されることになる。 上記の球面座部材１１にプッシュナット１２を挿入して収納した状態の正面図 を図５（Ａ）に示すとともに、そのＢ−Ｂ断面図を同図（Ｂ）に示し、Ｃ−Ｃ断 面図を同図（Ｃ）に示す。次に、上記図５（Ｂ），（Ｃ）両図と図１とを参照し つつ前記プッシュナット１２の組付方法について説明する。図５（Ｂ），（Ｃ） に示したように、球面座部材１１の空隙１１ｃの中へプッシュナット１２を挿入 し、駆動杆９ａの頭部を矢印ｊのごとく上記プッシュナット１２に突き通し、図 １に示したように球状部材９ａ1を球面座１１ａに嵌合する。図５（Ｃ）に示し た切欠１１ｄは前記球状部材９ａ1を嵌入するため球面座部材１１を撓み易くす るように設けたものである。 図２において駆動杆９ａを図の左右方向に前，後進させると、ブラケット７ｂ はリフレクタ７と一緒に傾動する。このため球面座部材１１は駆動杆９ａに対し て相対的に、球状部材９ａ1を中心として往復円弧矢印Ｌ−Ｒのごとく回動する 。ただし、この往復円弧矢印Ｌ−Ｒは回動の方向を表わしたものであって回動角 を示しているものではない。上記の回動を円滑ならしめるよう、球面座部材１１ がプッシュナット１２の周囲に接している面を球面１１ｅに成形してある。本図 １は断面を描いてあるので上記の球面は円弧として表わされている。図３（Ｂ） には上記の球面１１ｅの一部が現われている。 図１のように組みつけられた状態でプッシュナット１２は駆動杆９ａの突出杆 状部９ａ4を挟みつけており、反矢印ｊ方向に抜け出すことを防止しているが、 もし何らかの事情でプッシュナット１２が突出杆状部９ａ4に対して滑っても、 頭部９ａ2の段付部９ａ3に引っ懸かるので抜け止め防止効果は確実である。駆動 杆９ａが球面座部材１１に対して抜け出し方向に移動しないので、球状部材９ａ 1 が球面座１１ａから離脱するおそれが無い。また、上記球面座部材１１は、そ の溝１１ｂが突条７ｃと嵌合しているのでリフレクタのブラケット７ｂから脱出 するおそれが無い。FIG. 2 described above is a sectional view taken along a vertical plane passing through the axis of the drive rod 9a. FIG. 1 schematically shows a cross section taken along a horizontal plane passing through the axis of the drive rod 9a. Since this FIG. 1 is schematically illustrated for the convenience of understanding the configuration, it does not strictly follow the JIS drafting method such as hatching and the aspect ratio of members. A pair of mounting grooves 11b is provided on the outer surface of the spherical seat member 11. Correspondingly, a pair of protrusions 7c are integrally formed inside the bracket 7b of the reflector, and fit into the groove 11b to hold the spherical seat member 11 fixedly. FIG. 3 shows three views of the spherical seat member 11. The mounting groove 11b is represented by a hidden line in FIG. (A), a solid line in FIG. (B), and a contour in FIG. FIG. 4A shows a cross section taken along the line AA of FIG. 3 and FIG. 4B shows a cross section taken along the line BB. The groove 11b is shown in the contour of FIG. 4 (B). Reference numeral 11c shown in FIGS. 3 and 4 is a space for accommodating the push nut described above (FIG. 2). In this embodiment, the gap 11c is formed in a tunnel shape so that the push nut formed separately can be easily inserted into the gap 11c of the spherical seat member 11. That is, FIG. 4 (B) is a cross-sectional view of the tunnel-shaped void 11c cut vertically, and the push nut is inserted in the direction of arrow i. Further, FIG. 4A is a cross-sectional view of a shape that crosses the tunnel-shaped void 11c, and the push nut will be inserted in a direction intersecting with the paper surface. A front view of the state where the push nut 12 is inserted into the spherical seat member 11 and housed is shown in FIG. The figure is shown in FIG. Next, a method for assembling the push nut 12 will be described with reference to FIGS. 5 (B) and 5 (C) and FIG. As shown in FIGS. 5B and 5C, the push nut 12 is inserted into the space 11c of the spherical seat member 11, and the head of the drive rod 9a is pierced through the push nut 12 as indicated by an arrow j. , The spherical member 9a as shown in FIG.1To the spherical seat 11a. The notch 11d shown in FIG. 5C is the spherical member 9a.1The spherical seat member 11 is provided so that the spherical seat member 11 can be easily bent. In FIG. 2, when the drive rod 9a is moved forward and backward in the left-right direction in the figure, the bracket 7b tilts together with the reflector 7. Therefore, the spherical seat member 11 moves relative to the drive rod 9a relative to the spherical member 9a.1Rotate around the center as indicated by a reciprocating arc arrow LR. However, the reciprocating arc arrow L-R represents the direction of rotation and does not indicate the rotation angle. In order to smooth the above-mentioned rotation, the surface of the spherical seat member 11 which contacts the periphery of the push nut 12 is formed into a spherical surface 11e. Since FIG. 1 shows a cross section, the spherical surface is represented as an arc. A part of the spherical surface 11e is shown in FIG. 3 (B). In the assembled state as shown in FIG. 1, the push nut 12 has the protruding rod portion 9a of the drive rod 9a.FourThe push nut 12 is inserted into the protruding rod-shaped portion 9a for some reason.FourEven if you slide against the head 9a2Stepped portion 9a3Since it is caught in the area, the effect of preventing it from coming off is certain. Since the drive rod 9a does not move in the slip-out direction with respect to the spherical seat member 11, the spherical member 9a 1 There is no possibility of being separated from the spherical seat 11a. Further, since the groove 11b of the spherical seat member 11 is fitted to the ridge 7c, there is no possibility that the spherical seat member 11 will come out of the bracket 7b of the reflector.

However, as an embodiment different from the above (not shown), the same operation and effect can be obtained by applying to a unit movable type optical axis adjusting device for tilting the lamp housing with respect to the vehicle body. Further, the above-mentioned embodiment is an example in which the present invention is applied to an electrically operated optical axis adjusting device using the drive unit 9, but even if it is a manually operated type, the tilting operation force is transmitted through the ball joint. The present invention can be applied to the optical axis adjusting device, and the same operation and effect as in the above-mentioned embodiment can be obtained.
