Description

外れ難いフック構造及びこれを用いた車両用灯具Hard-to-disengage hook structure and vehicle lamp using the same
　本発明は外れ難いフック構造及びこれを用いた車両用灯具に関する。 The present invention relates to a hook structure that is difficult to come off and a vehicle lamp using the same.
　一般に、車両用灯具は、ハウジング、ブラケット、発光基板、リフレクタ、インナレンズ、エクステンション及びアウタレンズ等をねじ固定法、フック固定法及び熱板溶着法などによって組立てられている。 In general, vehicle lamps are assembled from housings, brackets, light-emitting substrates, reflectors, inner lenses, extensions, outer lenses, etc. by screw fixing, hook fixing, hot plate welding, and the like.
　例えば、特許文献１に記載の灯具は、一面が開口した箱形状をしたケースに光源が収容されており、このケースの開口を閉じるように板状の蓋部を有している。この灯具は、ケースの側方から突出した嵌合突部と、蓋部から板状に突出した垂下部とを有しており、垂下部の先端に設けられた開口が嵌合突部に引っ掛かかることで、ケースと蓋部とが上下方向で連結する。 For example, the lamp described in Patent Document 1 houses a light source in a box-shaped case with one side open, and has a plate-like lid to close the opening of the case. This lighting fixture has a fitting protrusion projecting from the side of the case and a hanging part projecting in a plate-like shape from the lid. By hooking, the case and the lid are connected in the vertical direction.
　また、比較例として図８に示すようなたとえば前後方向でも連結されるフック構造が車両用灯具に用いられている。 Further, as a comparative example, a hook structure that is connected also in the front-rear direction, for example, as shown in FIG. 8 is used for a vehicle lamp.
　図８の（Ａ）において、フック構造は、たとえばエクステンション側に設けられた第１の構造１００と、たとえばハウジング側に設けられた第２の構造２００とによって構成されている。第１の構造１００は板状であり、その先端部は傾斜面１００ａ、水平面１００ｂ及び垂直面１００ｃを有する。他方、第２の構造２００は、第１の構造１００の先端部を受ける溝部２０１ａを有する受け部２０１と、受け押え部２０２とを有する。さらに、受け部２０１は、溝部２０１ａの反対側の垂直面２０１ｂ、水平面２０１ｃ及び溝部２０１ａ側の垂直面２０１ｄを有する。 In FIG. 8A, the hook structure is composed of a first structure 100 provided on the extension side, for example, and a second structure 200 provided on the housing side, for example. The first structure 100 has a plate-like shape, and its tip portion has an inclined surface 100a, a horizontal surface 100b and a vertical surface 100c. On the other hand, the second structure 200 has a receiving portion 201 having a groove portion 201a for receiving the tip portion of the first structure 100 and a pressing portion 202 . Further, the receiving portion 201 has a vertical surface 201b opposite to the groove portion 201a, a horizontal surface 201c, and a vertical surface 201d on the side of the groove portion 201a.
　図８の（Ａ）のフック構造の組付け動作を図８の（Ｂ）～（Ｅ）を参照して説明する。 The assembly operation of the hook structure in FIG. 8(A) will be described with reference to FIGS. 8(B) to 8(E).
　始めに、図８の（Ｂ）の矢印ＡＲ１に示すごとく、エクステンションがハウジング側に近づくと、第１の構造１００が第２の構造２００に近づく。この結果、第１の構造１００の傾斜面１００ａが第２の構造２００の垂直面２０１ｂの下端を降下する。この結果、第１の構造１００は垂直方向に大きく撓む。 First, as the extension approaches the housing side, the first structure 100 approaches the second structure 200, as indicated by the arrow AR1 in FIG. 8B. As a result, the inclined surface 100a of the first structure 100 descends the lower end of the vertical surface 201b of the second structure 200. FIG. As a result, the first structure 100 flexes significantly in the vertical direction.
　さらに、図８の（Ｃ）の矢印ＡＲ２に示すごとく、エクステンションがハウジング側に近づくと、第２の構造２００の垂直面２０１ｂの下端において第１の構造１００の傾斜面１００ａの接触から第１の構造１００の水平面１００ｂの接触に切替わる。この場合、第１の構造１００を受け押え部２０２によって押えられる。 Further, as indicated by an arrow AR2 in FIG. 8C, when the extension approaches the housing side, the contact of the inclined surface 100a of the first structure 100 at the lower end of the vertical surface 201b of the second structure 200 causes the first extension to move. Switch to contacting the horizontal surface 100b of the structure 100 . In this case, the first structure 100 is held down by the holding portion 202 .
　さらに、図８の（Ｄ）の矢印ＡＲ３に示すごとく、エクステンションがハウジング側に近づくと、第１の構造１００の水平面１００ｂと第２の構造２００の水平面２０１ｃとが接触して摺動し、第１の構造１００は撓みながら摺動する。 Further, as indicated by an arrow AR3 in FIG. 8D, when the extension approaches the housing side, the horizontal surface 100b of the first structure 100 and the horizontal surface 201c of the second structure 200 come into contact with each other and slide. Structure 100 of 1 slides while bending.
　さらに、図８の（Ｅ）の矢印ＡＲ４に示すごとく、エクステンションがハウジング側に近づくと、第１の構造１００の撓みが解除され、第１の構造１００の垂直面１００ｃが第２の構造２００の垂直面２０１ｄと接触し、第１の構造１００と第２の構造２００との組付け動作は終了する。 Furthermore, as indicated by arrow AR4 in FIG.

　しかしながら、上述の比較例としてのフック構造においては、第１の構造１００の先端部が第２の構造２００の溝部２０１ａに引っ掛かっているだけであり、たとえば上下振動によってフック構造が外れてしまうという課題がある。すなわち、図９に示すごとく、図８に示した比較例のフック構造では、組付け動作の際には、第１の構造１００は撓んで変形し、その後、撓みを解除するが、第１の構造１００の先端部が第２の構造２００の溝部２０１ａ内に十分入り込めず、引っ掛かりの掛り代Ｋ２が不足することがある。また、垂直面（１００ｃ、２０１ｄ）しか引っ掛かっておらず、第１の構造１００の先端部は押えられていないので、上下振動などにより外れてしまうおそれもある。また、撓ませる為に弾性変形しやすい形状にしている為、振動などにより意図せず変形しフック構造が外れてしまうおそれがある。 However, in the hook structure as the comparative example described above, the tip portion of the first structure 100 is merely hooked on the groove portion 201a of the second structure 200, and the hook structure is disengaged due to, for example, vertical vibration. There is That is, as shown in FIG. 9, in the hook structure of the comparative example shown in FIG. The tip of the structure 100 may not be able to enter the groove 201a of the second structure 200 sufficiently, and the catching allowance K2 may be insufficient. Moreover, since only the vertical surfaces (100c, 201d) are hooked and the tip of the first structure 100 is not pressed, there is a possibility that it may come off due to vertical vibration or the like. In addition, since it is made to be elastically deformable in order to be bent, there is a risk that the hook structure will be unintentionally deformed due to vibration or the like and the hook structure will come off.
　上述の課題を解決するために、本発明に係るフック構造は、第１の構造を第２の構造に第１の方向に組付けて構成されるフック構造において、第１の構造は、第１の方向に沿って板状に設けられた台座と、台座の一面において、第１の方向と直交する第２の方向へ突出するように設けられた筒状部とを具備し、第２の構造は、筒状部が挿し込まれるための開口部、及び第１の方向において開口部と連続して設けられ筒状部が係合するための溝部を有する受け部を具備するものである。 In order to solve the above problems, a hook structure according to the present invention is a hook structure configured by assembling a first structure to a second structure in a first direction, wherein the first structure A second structure comprising a plate-shaped pedestal along the direction of and a tubular portion provided on one surface of the pedestal so as to protrude in a second direction orthogonal to the first direction is provided with an opening into which the tubular portion is inserted, and a receiving portion provided continuously with the opening in a first direction and having a groove for engaging the tubular portion.
　また、本発明に係る車両用灯具は、上述のフック構造を具備するものである。 Further, a vehicle lamp according to the present invention has the hook structure described above.
　本発明によれば、組込の際に、第１の構造の筒状部の側面を第２の構造の受け部が囲むように保持することができ、振動などの要因によって第１の構造と第２の構造との係合状態が解除されるのを抑制することができる。 According to the present invention, during assembly, the side surface of the cylindrical portion of the first structure can be held so as to be surrounded by the receiving portion of the second structure. Disengagement of the engagement state with the second structure can be suppressed.

The upward direction U, downward direction D, leftward direction L, rightward direction R, forward direction F, and rearward direction B in the drawings of the present application are directions viewed from the driver of the vehicle. Further, the vertical direction U/D is defined as a first direction, the front/rear direction F/B is defined as a second direction, and the horizontal direction L/R is defined as a third direction. In this case, the first direction, the second direction and the third direction are directions orthogonal to each other. Also, the description has been given using the left front lamp, but it is only an example, and the present invention can also be applied to the right front lamp with the left-right direction L/R as the target.
　図２は図１の車両用灯具の分解斜視図である。 FIG. 2 is an exploded perspective view of the vehicle lamp of FIG.
　図２に示すように、車両用灯具は、ハウジング１、ハウジング１上に設けられたブラケット／光源／リフレクタアッシ２、ブラケット／光源／リフレクタアッシ２を保護するエクステンション３及び灯室を規定するアウタレンズ４よりなる。ハウジング１は内側に収容空間を有し、ブラケット／光源／リフレクタアッシ２がこの収容空間に収容されるように取り付けられる。ブラケット／光源／リフレクタアッシ２は、ロービーム用プロジェクタ光源ＬＢＰ１、ＬＢＰ２、ロービーム用リフレクタ光源ＬＢＲ１、ＬＢＲ２及びハイビーム用プロジェクタ光源ＨＢＰの発光ダイオード（ＬＥＤ）素子基板及びリフレクタを有する。エクステンション３は、前方向Ｆから見た正面図においてＣ字形状に形成されており、ハウジング１およびブラケット／光源／リフレクタアッシ２の縁を覆うようにハウジング１に取り付けられている。 As shown in FIG. 2, the vehicle lamp includes a housing 1, a bracket/light source/reflector assembly 2 provided on the housing 1, an extension 3 protecting the bracket/light source/reflector assembly 2, and an outer lens 4 defining a lamp chamber. consists of The housing 1 has an accommodation space inside, and the bracket/light source/reflector assembly 2 is attached so as to be accommodated in this accommodation space. The bracket/light source/reflector assembly 2 includes light emitting diode (LED) element substrates and reflectors for low beam projector light sources LBP1 and LBP2, low beam reflector light sources LBR1 and LBR2, and high beam projector light source HBP. The extension 3 is formed in a C shape in a front view seen from the front direction F, and is attached to the housing 1 so as to cover edges of the housing 1 and the bracket/light source/reflector assembly 2 .
　図２の車両用灯具の組立方法は以下の通りである。始めに、ブラケット／光源／リフレクタアッシ２をハウジング１にねじ固定によって組立て、次いで、エクステンション３をハウジング１にねじ固定及びフック固定によって組立て、最後に、アウタレンズ４をハウジング１に嵌合して熱板溶着する。 The method of assembling the vehicle lamp in Fig. 2 is as follows. First, the bracket/light source/reflector assembly 2 is assembled to the housing 1 by screws and then the extension 3 is assembled to the housing 1 by screws and hooks. Weld.
　尚、本実施例においては、エクステンション３とハウジング１との固定は３ヶ所で行い、外観上見え易い左外側下部の１ヶ所をフック固定とし、他の２ヶ所をねじ固定とするが、これに限定されるものではない。但し、エクステンション３とハウジング１とを連結する左外側下部の右端部側をフック固定としたのは、エクステンション３とハウジング１との当該場所に隙間ができる箇所であり、この隙間を介してねじ頭などが外部から確認できてしまうのを抑制する為である。 In this embodiment, the extension 3 and the housing 1 are fixed at three points, one point on the lower left outer side, which is easily visible from the outside, is fixed with a hook, and the other two points are fixed with screws. It is not limited. However, the reason why the right end of the left outer lower portion connecting the extension 3 and the housing 1 is fixed by the hook is that there is a gap between the extension 3 and the housing 1, and the screw head is inserted through this gap. It is for suppressing that etc. can be confirmed from the outside.
　次に、本実施例のフック構造について説明をする。フック構造は、エクステンション３に設けられた第１の構造１０が、ハウジング１に設けられた第２の構造２０に、前側から後側に向かって挿し込まれて係合するものである。 Next, the hook structure of this embodiment will be explained. In the hook structure, a first structure 10 provided on the extension 3 is inserted into and engaged with a second structure 20 provided on the housing 1 from the front side to the rear side.
　図３はフック構造を構成する第１の構造１０を説明するための図であって、（Ａ）はエクステンション３の正面図、（Ｂ）は（Ａ）のエクステンション３の左外側下部に設けられた第１の構造１０の拡大下面図、（Ｃ）は第１の構造１０の拡大下面斜視図である。 3A and 3B are views for explaining the first structure 10 constituting the hook structure, FIG. 3A being a front view of the extension 3, and FIG. 2C is an enlarged bottom perspective view of the first structure 10. FIG.
　図３の（Ａ）に示すように、第１の構造１０はエクステンション３の左外側下部に設けられる。 As shown in (A) of FIG. 3 , the first structure 10 is provided on the lower left outer side of the extension 3 .
　第１の構造１０は、円形筒状部１１と、円形筒状部１１を支持しエクステンション３側の押面１２ａに設けられた台座１２と、台座１２の端部に位置する押面１２ａと円形筒状部１１とを繋げて台座１２に上下方向Ｕ／Ｄへの撓みに対する剛性を向上させる台座リブ１３ａ、１３ｂとを有する。台座１２はエクステンション３側の押面１２ａから突設している。尚、台座リブ１３ａ、１３ｂは１本又は３本以上でもよい。 The first structure 10 includes a circular cylindrical portion 11, a pedestal 12 supporting the circular cylindrical portion 11 and provided on a pressing surface 12a on the side of the extension 3, a pressing surface 12a located at the end of the pedestal 12, and a circular shape. The pedestal 12 has pedestal ribs 13a and 13b that connect the tubular portion 11 and improve rigidity against bending in the vertical direction U/D. The pedestal 12 protrudes from the pressing surface 12a on the extension 3 side. Incidentally, the number of the base ribs 13a and 13b may be one or three or more.
　円形筒状部１１は、円柱の内側が空間になっている筒状形状をなしており、台座１２から下方向Ｄへ突設するように設けられている。
　台座１２は板状に設けられており、前後方向Ｆ／Ｂに沿って延設するように設けられている。円形筒状部１１と押面１２ａとは、前後方向Ｆ／Ｂにおいて対向するように台座１２から突出して設けられている。
　台座リブ１３ａ、１３ｂは、円形筒状部１１と押面１２ａとを繋げるように台座１２から突出して設けられている。
　台座リブ１３ａ、１３ｂは、エクステンション３の本体からの前後方向Ｆ／Ｂの応力を円形筒状部１１に組付け圧力として伝達するものである。なお、台座リブ１３ａ、１３ｂを設けることで、台座１２の板厚を小さくしてもよい。 The circular cylindrical portion 11 has a cylindrical shape with a space inside the cylinder, and is provided so as to protrude downward D from the base 12 .
The pedestal 12 is provided in a plate shape and is provided so as to extend along the front-rear direction F/B. The circular tubular portion 11 and the pressing surface 12a are provided so as to protrude from the pedestal 12 so as to face each other in the front-rear direction F/B.
The pedestal ribs 13a and 13b are provided so as to protrude from the pedestal 12 so as to connect the circular tubular portion 11 and the pressing surface 12a.
The base ribs 13a and 13b transmit the stress in the longitudinal direction F/B from the main body of the extension 3 to the circular cylindrical portion 11 as assembly pressure. The plate thickness of the pedestal 12 may be reduced by providing the pedestal ribs 13a and 13b.
　円形筒状部１１の外周軸方向に突起リブ１１ａ、１１ｂを設ける。
　突起リブ１１ａ、１１ｂは、円形筒状部１１の側面から放射状に突設し、複数設けられている。突起リブ１１ａ、１１ｂはハウジング１の後述の第２の構造２０の受け部２１の円形溝２１ａに当接し、組付後に円形筒状部１１が円形溝２１ａの内側を意図せず動いてしまうのを抑えることができる。尚、突起リブ１１ａ、１１ｂの数は、前後方向Ｆ／Ｂおよび左右方向Ｌ／Ｒへの移動を抑制できる数であれば良く、１つ又は３つ以上とすることもできる。　 Protrusive ribs 11a and 11b are provided in the axial direction of the outer periphery of the circular cylindrical portion 11. As shown in FIG.
The projecting ribs 11a and 11b project radially from the side surface of the circular cylindrical portion 11 and are provided in plurality. The projecting ribs 11a and 11b abut on the circular groove 21a of the receiving portion 21 of the second structure 20 of the housing 1, which prevents the circular tubular portion 11 from unintentionally moving inside the circular groove 21a after assembly. can be suppressed. Incidentally, the number of projecting ribs 11a and 11b may be any number that can suppress movement in the front-back direction F/B and the left-right direction L/R, and may be one or three or more.
　突起リブ１１ａ、１１ｂを含めて円形筒状部１１は台座１２から離れる程小径となっている。つまり、突起リブ１１ａ、１１ｂは上下方向Ｕ／Ｄにおいて傾斜するように設けられている。これにより、上下方向Ｕ／Ｄにおいて突起リブ１１ａ、１１ｂが円形溝２１ａに引っ掛かり、円形筒状部１１が円形溝２１ａに対して下方向Ｄへ移動するのを抑制することができる。 The diameter of the circular tubular portion 11, including the projecting ribs 11a and 11b, becomes smaller as the distance from the base 12 increases. That is, the projecting ribs 11a and 11b are provided so as to be inclined in the vertical direction U/D. As a result, the projecting ribs 11a and 11b are caught in the circular groove 21a in the vertical direction U/D, and the circular tubular portion 11 can be prevented from moving in the downward direction D with respect to the circular groove 21a.
　次に、本実施例のフック構造の他方である第２の構造２０について説明をする。 Next, the second structure 20, which is the other hook structure of this embodiment, will be described.
　図４は第２の構造２０を説明するための図であって、（Ａ）はハウジング１の正面図、（Ｂ）は（Ａ）のハウジング１の左外側下部に設けられた第２の構造２０の拡大正面図、（Ｃ）は（Ｂ）の第２の構造２０の下面図、（Ｄ）は（Ｂ）の第２の構造２０の下面斜視図である。 4A and 4B are diagrams for explaining the second structure 20, in which (A) is a front view of the housing 1, and (B) is the second structure provided on the lower left outer side of the housing 1 in (A). 20 is an enlarged front view, (C) is a bottom view of the second structure 20 of (B), and (D) is a bottom perspective view of the second structure 20 of (B).
　図４の（Ａ）に示すように、第２の構造２０はハウジング１の左外側下部に設けられる。第２の構造２０は、前後方向Ｆ／Ｂにおいて第１の構造１０と対向する位置に設けられている。 As shown in FIG. 4(A), the second structure 20 is provided on the lower left outer side of the housing 1 . The second structure 20 is provided at a position facing the first structure 10 in the front-rear direction F/B.
　第２の構造２０は、板状の受け部２１と、受け部２１の上方向Ｕに受け部２１と対向するよう板状に設けられた受け押え部２２を有している。 The second structure 20 has a plate-shaped receiving portion 21 and a plate-like holding portion 22 facing the receiving portion 21 in the upward direction U of the receiving portion 21 .
　受け部２１は、前側が円形筒状部１１が挿し込まれるように開口部２１ｃが開口され、この開口部２１ｃと連続して設けられ第１の構造１０の円形筒状部１１を保持する円形溝２１ａを有している。この開口部２１ｃは、左右方向において前側が円形溝２１ａ側よりも大きく形成されており、円形筒状部１１が挿し込まれる際に誘導するように傾斜したガイド部２１ｂを有している。また、左右方向Ｌ／Ｒにおいて、円形溝２１ａの開口と連通
する箇所の大きさは円形筒状部１１の左右方向Ｌ／Ｒの大きさより小さく、円形溝２１ａの径方向の大きさは円形筒状部１１（突起リブ１１ａ、１１ｂを含まない箇所にて）の左右方向Ｌ／Ｒの大きさより大きく形成されている。受け部２１は、円形筒状部１１が開口部２１ｃに挿し込まれた際、開口部２１ｃが左右方向Ｌ／Ｒへ広がるように弾性し、円形筒状部１１が円形溝２１ａに収容される。
　また、受け部２１は、ハウジング１の本体と斜めに接続するように着地面リブ２３を有しており、受け部２１が上下方向Ｕ／Ｄへ変形もしくは破損するのを抑制されている。 The receiving portion 21 has an opening 21c on the front side so that the circular cylindrical portion 11 can be inserted therein. It has a groove 21a. The opening 21c has a front side that is larger than the circular groove 21a side in the left-right direction, and has a guide portion 21b that is inclined to guide the circular cylindrical portion 11 when it is inserted. In addition, in the left-right direction L/R, the size of the portion communicating with the opening of the circular groove 21a is smaller than the size of the left-right direction L/R of the circular tubular portion 11, and the radial size of the circular groove 21a is the size of the circular cylinder. It is formed to be larger than the lateral L/R size of the shaped portion 11 (at locations not including the projecting ribs 11a and 11b). When the circular tubular portion 11 is inserted into the opening 21c, the receiving portion 21 is elastic so that the opening 21c expands in the left-right direction L/R, and the circular tubular portion 11 is accommodated in the circular groove 21a. .
Further, the receiving portion 21 has a landing surface rib 23 so as to be obliquely connected to the main body of the housing 1, thereby suppressing deformation or breakage of the receiving portion 21 in the vertical direction U/D.
　受け押え部２２は、組付け後の第１の構造１０の上方向Ｕへの移動を抑制する為のものである下振動を抑止するためのものである。受け押え部２２は、下側の面に前後方向Ｆ／Ｂに亘って突設した摺動リブ２２ａを有する。摺動リブ２２ａの左右方向Ｌ／Ｒの大きさは受け押え部２２の左右方向Ｌ／Ｒの大きさよりも小さく形成されている。 The receiving and holding portion 22 is for suppressing downward vibration, which is for suppressing upward movement of the first structure 10 after assembly. The receiving and holding portion 22 has a sliding rib 22a projecting in the front-rear direction F/B on its lower surface. The size of the lateral L/R of the sliding rib 22a is formed smaller than the size of the lateral L/R of the receiving and pressing portion 22. As shown in FIG.
　第１の構造１０が第２の構造２０に組込み後、第１の構造１０の台座１２は第２の構造２０の受け部２１と受け押え部２２とによって挟持される。着地面リブ２３は組込み時の受け部２１の折れや変形を抑止する。 After the first structure 10 is incorporated into the second structure 20 , the pedestal 12 of the first structure 10 is sandwiched between the receiving portion 21 and the pressing portion 22 of the second structure 20 . The landing surface rib 23 prevents the receiving portion 21 from being bent or deformed during assembly.
　また、受け押え部２２の摺動リブ２２ａは、第１の構造１０が挿し込まれた際に台座１２が摺動する箇所である。摺動リブ２２ａは台座１２との抵抗を少なくして組付けを容易にすると共に、組付け後に第１の構造１０を下方向Ｄへ押圧へ押圧するものであり、第１の構造１０の上下方向Ｕ／Ｄへの意図しない移動を抑止するものである。 Further, the sliding rib 22a of the receiving and holding portion 22 is a portion where the base 12 slides when the first structure 10 is inserted. The sliding ribs 22a reduce the resistance with the base 12 to facilitate assembly, and also press the first structure 10 in the downward direction D after assembly. This prevents unintended movement in the U/D direction.
　図５は図３の第１の構造１０と図４の第２の構造２０との組付け動作を説明するための図であって、（Ａ）は組付け前の第１、第２の構造の状態を示す側面図、（Ｂ）は組付け後の第１、第２の構造の状態を示す側面図、（Ｃ）は組付け後の第１、第２の構造の状態を示す下面図、（Ｄ）は（Ｃ）のＤ－Ｄ線断面図、（Ｅ）は（Ｃ）のＥ－Ｅ線断面図である。尚、図５の（Ａ）、（Ｂ）においては、第２の構造２０について受け部２１及び受け押え部２２のみを簡易に示してある。 5A and 5B are diagrams for explaining the operation of assembling the first structure 10 of FIG. 3 and the second structure 20 of FIG. (B) is a side view showing the state of the first and second structures after assembly, (C) is a bottom view showing the state of the first and second structures after assembly , (D) is a sectional view taken along line DD of (C), and (E) is a sectional view taken along line EE of (C). 5A and 5B, only the receiving portion 21 and the receiving pressing portion 22 of the second structure 20 are simply shown.
　図５の（Ａ）の矢印ＡＲ、ＡＲ’に示すごとく、第１の構造１０を第２の構造２０に接近させると、図５の（Ｂ）、（Ｃ）に示すごとく、第１の構造１０の円形筒状部１１が第２の構造２０の円形溝２１ａに向って後方向撓み（応力）ＨＤの方向に進むので、第１の構造１０の上下方向撓み（応力）ＶＤは小さい。また、たとえ上下方向撓み（応力）ＶＤがあっても、図５の（Ｃ）に示す台座リブ１３ａ（１３ｂ）による挿し込み方向への補強によって上下方向撓み（応力）ＶＤが緩和されて台座１２が折れたり変形が抑制される。従って、第１の構造１０が上下方向Ｕ／Ｄへ変形することなく第２の構造２０に挿し込むことができ、組付することが容易となる。また、押面１２ａを介して後方向へ移動させる力を的確に伝えることができる。
　また、台座リブ１３ａにより台座１２の強度が向上することで、振動などの外的要因により第１の構造１０が上下方向Ｕ／Ｄへ意図せずに変形もしくは破損してしまうことを抑制することができる。 When the first structure 10 approaches the second structure 20 as indicated by arrows AR and AR' in FIG. Since the circular tubular portion 11 of 10 advances in the direction of the backward deflection (stress) HD toward the circular groove 21a of the second structure 20, the vertical deflection (stress) VD of the first structure 10 is small. Further, even if there is a vertical deflection (stress) VD, the vertical deflection (stress) VD is relieved by reinforcement in the insertion direction by the base ribs 13a (13b) shown in FIG. is suppressed from breaking and deformation. Therefore, the first structure 10 can be inserted into the second structure 20 without being deformed in the vertical direction U/D, facilitating assembly. In addition, the force for moving backward can be accurately transmitted via the pressing surface 12a.
In addition, since the strength of the base 12 is improved by the base ribs 13a, the first structure 10 can be prevented from being unintentionally deformed or damaged in the vertical direction U/D due to external factors such as vibration. can be done.
　また、組付け後も、第１の構造１０の円形筒状部１１と第２の構造２０の受け部２１の円形溝２１ａは、円形溝２１ａが円形筒部２１ａの周方向で覆うように保持しているので外れ難い。 Further, even after assembly, the circular tubular portion 11 of the first structure 10 and the circular groove 21a of the receiving portion 21 of the second structure 20 are held so that the circular groove 21a covers the circular tubular portion 21a in the circumferential direction. It is hard to come off because it is attached.
　また、突起リブ１１ａ、１１ｂによって、円形溝２１ａの内側に亘って接触しているので、振動などにより前後方向Ｆ／Ｂ、左右方向Ｌ／Ｒおよび上下方向Ｕ／Ｄへの意図しない移動を抑制することができる。 In addition, since the protruding ribs 11a and 11b are in contact with the inside of the circular groove 21a, unintended movement in the front-back direction F/B, left-right direction L/R, and up-down direction U/D due to vibration is suppressed. can do.
　また、図５の（Ｃ）、（Ｄ）、（Ｅ）に示すごとく、円形筒状部１１に突起リブ１１ａ、１１ｂを設けると共に、受け押え部２２に摺動リブ２２ａを設けているので、組付け後の第１の構造１０と第２の構造２０との透き詰めがさらに可能となり、さらにがたつきを抑えかつ振動性能を向上できる。 Further, as shown in FIGS. 5C, 5D, and 5E, projecting ribs 11a and 11b are provided on the circular cylindrical portion 11, and a sliding rib 22a is provided on the pressing portion 22. The first structure 10 and the second structure 20 can be more transparently assembled after being assembled, so that rattling can be suppressed and vibration performance can be improved.
　図６は、図３のエクステンション３を図４のハウジング１に取り付ける工程を説明するための下方向Ｄから視た斜視図であり、図６の（Ａ）は組付け前であり、図６の（Ｂ）は組付け後であり、図６の（Ａ）の状態からエクステンション３を後方向Ｂへ移動させたものである。エクステンション３の押面１２ａの内側（前方側）に操作窪み部３ａを設ける。すなわち、操作窪み部３ａは押面１２ａの台座１２の反対側に設けられる。第１の構造１０を第２の構造２０に挿し込む際は、この操作窪み部３ａに作業者の指や機器が挿し込まれ押面１２ａが後方向Ｂに押されて組付けされる。なお、操作窪み部３ａはエクステンション３の下側枠部に下方向Ｄから上方向Ｕに窪むように形成され、灯具を正面から視た際に外観上に現れ難くしている。 6A and 6B are perspective views of the extension 3 shown in FIG. 3 as viewed from the downward direction D for explaining the process of attaching the extension 3 shown in FIG. 3 to the housing 1 shown in FIG. (B) shows the state after assembly, in which the extension 3 is moved in the rearward direction B from the state shown in (A) of FIG. 6 . An operation recess portion 3a is provided inside (front side) of the pressing surface 12a of the extension 3. As shown in FIG. That is, the operation recessed portion 3a is provided on the opposite side of the pedestal 12 of the pressing surface 12a. When inserting the first structure 10 into the second structure 20, an operator's finger or a device is inserted into the operation recess 3a, and the push surface 12a is pushed backward B for assembly. The operation recess 3a is formed in the lower frame of the extension 3 so as to be recessed from the downward direction D to the upward direction U, so that it does not appear easily when the lamp is viewed from the front.
　図７は図３の円形筒状部１１の変更例を示す下面図である。 FIG. 7 is a bottom view showing a modified example of the circular tubular portion 11 of FIG.
　図７に示すように、図３の円形筒状部１１の代りに、多角形筒状部（たとえば菱形筒状部）１１’を設ける。この場合、多角形筒状部１１’のエッジ部が図３の突起リブ１１ａ、１１ｂの作用をするので、図３の突起リブ１１ａ、１１ｂは設ける必要がない。この多角形筒状部１１’は円形筒状部１１とほぼ同一の作用をし、フック構造を強固にする。 As shown in FIG. 7, instead of the circular tubular portion 11 in FIG. 3, a polygonal tubular portion (for example, rhombic tubular portion) 11' is provided. In this case, since the edges of the polygonal tubular portion 11' act as the protruding ribs 11a and 11b shown in FIG. 3, the protruding ribs 11a and 11b shown in FIG. 3 are not required. This polygonal tubular portion 11' performs substantially the same function as the circular tubular portion 11 and strengthens the hook structure.
　また、エクステンション３は、フック構造の係合が強くなることで、エクステンション３がハウジング１から外れ難くなるとともに、ハウジング１の補強としても作用する。フック構造が強化されることで、ハウジング１への負荷をフック構造がはずれることなくなくエクステンション３に伝えることができ、エクステンション３が負荷を吸収することができる。 In addition, the extension 3 has a stronger engagement with the hook structure, which makes it difficult for the extension 3 to come off the housing 1 and also acts as a reinforcement for the housing 1 . By strengthening the hook structure, the load on the housing 1 can be transmitted to the extension 3 without the hook structure coming off, and the extension 3 can absorb the load.
　尚、上述の実施例においては、第１の構造１０をエクステンション３側に設け、第２の構造２０をハウジング１側に設けているが、第１の構造１０をハウジング１側に設け、第２の構造２０をエクステンション３側に設けてもよい。また、本発明に係るフック構造は車両用灯具のエクステンション３及びハウジング１との間ではなく、他の部品間に設けてもよい。 In the above-described embodiment, the first structure 10 is provided on the extension 3 side and the second structure 20 is provided on the housing 1 side. structure 20 may be provided on the extension 3 side. Further, the hook structure according to the present invention may be provided not between the extension 3 and the housing 1 of the vehicle lamp, but between other parts.
　また、エクステンション３は、前側から視た際にＣ字形状として、ねじとフック構造の両方でハウジングで固定していたが、エクステンション３はＣ字形状でなく、直線形状でもよく、矩形形状であってもよい。
　また、ねじを用いずにすべてフック構造で組付けしてもよく、フック構造の数を増やしより外れ難くしてもよい。 Further, the extension 3 has a C shape when viewed from the front side and is fixed by the housing with both a screw and a hook structure, but the extension 3 may have a linear shape instead of a C shape, or may have a rectangular shape. may
Alternatively, the hook structure may be used for assembly without screws, or the number of hook structures may be increased to make it more difficult to remove.
　さらに、本発明は上述の実施例の自明の範囲でいかなる変更にも適用できる。 Furthermore, the present invention can be applied to any modification within the obvious scope of the above-described embodiments.
　本発明に係るフック構造は車両用灯具以外でも、２つの樹脂部品間の結合に利用できる。 The hook structure according to the present invention can be used for joining two resin parts other than vehicle lamps.
