Description

本発明は再帰反射装置に関する。   The present invention relates to a retroreflective device.

従来、車両用灯具には、再帰反射板が設けられている（例えば、特許文献１参照）。特許文献１に記載の技術では、車両用灯具のハウジング（３）に取付凹部（区画４６）が設けられており、再帰反射板（リフレックスリフレクタ６）がその取付凹部を塞ぐようにしてその取付凹部（４６）に取り付けられている。再帰反射板の裏側であって取付凹部の底面には窪みが形成され、その窪みによる段差（３１ｃａ）が形成されている。   Conventionally, a vehicular lamp is provided with a retroreflective plate (see, for example, Patent Document 1). In the technique described in Patent Document 1, a mounting recess (section 46) is provided in a housing (3) of a vehicular lamp, and the retroreflector (reflex reflector 6) is attached so as to block the mounting recess. It is attached to the recess (46). A recess is formed in the bottom surface of the mounting recess on the back side of the retroreflective plate, and a step (31ca) is formed by the recess.

特開２０１１−２３３２５０号公報JP 2011-233250 A

再帰反射板は光を再帰反射するものであるが、僅かな光が再帰反射板を通過する。そのため、再帰反射板の裏側にある窪みに陰が形成され、窪みの像が再帰反射板に映ることがある。
そこで、本発明が解決しようとする課題は、再帰反射板越しに取付凹部の底面を見た場合に、窪みとその周囲の底面とを視覚的に識別できないようにすることである。 The retroreflecting plate retroreflects light, but a small amount of light passes through the retroreflecting plate. Therefore, a shadow is formed in the depression on the back side of the retroreflective plate, and an image of the depression may be reflected on the retroreflective plate.
Therefore, the problem to be solved by the present invention is to make it impossible to visually identify the recess and the surrounding bottom surface when the bottom surface of the mounting recess is viewed through the retroreflective plate.

以上の課題を解決するために、請求項１に係る発明は、保持部材と、前記保持部材に形成された取付凹部と、前記取付凹部の底面に形成された窪みと、前記取付凹部に嵌め込まれた再帰反射板と、前記取付凹部の周壁部に形成された爪と、前記再帰反射板の裏側の面の縁寄りに設けられたフックと、を備え、前記取付凹部の前記底面及び前記窪みがシボ加工されており、前記窪みが前記取付凹部の前記底面のうち前記取付凹部の前記周壁部寄りに形成され、前記爪が前記取付凹部の前記周壁部のうち前記窪みに沿う部位に形成され、前記フックが前記爪に引っ掛かることを特徴とする再帰反射装置である。 In order to solve the above problems, the invention according to claim 1 is fitted into the holding member, the mounting recess formed in the holding member, the recess formed in the bottom surface of the mounting recess, and the mounting recess. A retroreflecting plate, a claw formed on the peripheral wall portion of the mounting recess, and a hook provided near the edge of the back surface of the retroreflecting plate, and the bottom surface and the recess of the mounting recess It is textured , the recess is formed near the peripheral wall portion of the mounting recess in the bottom surface of the mounting recess, and the claw is formed in a portion along the recess in the peripheral wall portion of the mounting recess, The retroreflective device is characterized in that the hook is caught on the claw .

本発明によれば、再帰反射板を通過した光がシボ加工によって乱反射されるから、取付凹部の底面に形成された窪みの像が再帰反射板の表面に非常にぼけて映る。よって、再帰反射板越しに取付凹部の底面を見た場合、窪みとその周囲の底面とを視覚的に識別することができない。   According to the present invention, since the light that has passed through the retroreflective plate is irregularly reflected by the embossing process, the image of the dent formed on the bottom surface of the mounting concave portion is reflected on the surface of the retroreflective plate very much. Therefore, when the bottom surface of the mounting recess is viewed through the retroreflecting plate, the depression and the surrounding bottom surface cannot be visually identified.

FIG. 2 is a cross-sectional view showing the surface along II-II shown in FIG. 1 as viewed in the direction of the arrow. FIG. 3 is an enlarged view of a region III shown in FIG.

この再帰反射装置（リフレックスリフレクタ）１は自動車に取り付けられるものであっって、自動車の後部又は側部を表示する表示器として利用される。より具体的には、この再帰反射装置１が車両用灯具（テールランプ、ストップランプ、ターンシグナルランプ、リアコンビネーションランプその他信号灯）に組み込まれており、この再帰反射装置１と車両用灯具がユニット化されて、その灯具ユニットが車両に取り付けられる。   The retroreflective device (reflex reflector) 1 is attached to an automobile and is used as a display for displaying the rear or side of the automobile. More specifically, the retroreflective device 1 is incorporated in a vehicle lamp (tail lamp, stop lamp, turn signal lamp, rear combination lamp or other signal lamp), and the retroreflective device 1 and the vehicle lamp are unitized. Then, the lamp unit is attached to the vehicle.

再帰反射装置１は保持部材１０及び再帰反射板２０等を備える。
この保持部材１０は車両用灯具のハウジング、エクステンション又はリフレクタ等の部品９９と一体に成型されたものである。保持部材１０には取付凹部１１及び囲い壁部１２が形成されおり、取付凹部１１が囲い壁部１２によって囲われており、囲い壁部１２が取付凹部１１の内周壁を構成する。なお、素通しのアウターレンズが保持部材１０の表側から部品９９に取り付けられ、アウターレンズと再帰反射板２０と保持部材１０の三重構造が前記灯具ユニットの側部に設けられてもよい。 The retroreflective device 1 includes a holding member 10 and a retroreflective plate 20.
This holding member 10 is formed integrally with a part 99 such as a housing, extension or reflector of a vehicle lamp. An attachment recess 11 and an enclosure wall 12 are formed in the holding member 10, the attachment recess 11 is surrounded by the enclosure wall 12, and the enclosure wall 12 constitutes an inner peripheral wall of the attachment recess 11. A transparent outer lens may be attached to the component 99 from the front side of the holding member 10, and a triple structure of the outer lens, the retroreflective plate 20, and the holding member 10 may be provided on the side of the lamp unit.

取付凹部１１の底面１１ａは平面であるか、曲率が小さくて緩やかに湾曲した曲面である。取付凹部１１の底面１１ａに窪み１３が形成されており、その窪み１３に爪１４が形成されている。より具体的には、窪み１３が取付凹部１１の底面１１ａうち取付凹部１１の内周壁（囲い壁部１２）寄りの部位に形成されており、爪１４が囲い壁部１２のうち窪み１３に沿う部位に形成されている。爪１４は囲い壁部１２から取付凹部１１の内側へ突出し、窪み１３の凹む方向に見て爪１４が窪み１３の一部に重なっている。取付凹部１１が浅く、取付凹部１１の底面１１ａを基準とした囲い壁部１２の高さが低い場合でも、窪み１３が形成されていることによって爪１４を囲い壁部１２に形成し、爪１４の裏側にスペースを確保することができる。   The bottom surface 11a of the mounting recess 11 is a flat surface or a curved surface that has a small curvature and is gently curved. A recess 13 is formed in the bottom surface 11 a of the mounting recess 11, and a claw 14 is formed in the recess 13. More specifically, the recess 13 is formed in a portion of the bottom surface 11 a of the attachment recess 11 near the inner peripheral wall (enclosure wall portion 12) of the attachment recess 11, and the claw 14 extends along the recess 13 of the enclosure wall portion 12. It is formed at the site. The claw 14 protrudes from the surrounding wall 12 to the inside of the mounting recess 11, and the claw 14 overlaps a part of the recess 13 when viewed in the direction in which the recess 13 is recessed. Even when the mounting recess 11 is shallow and the height of the surrounding wall portion 12 with respect to the bottom surface 11a of the mounting recess 11 is low, the claw 14 is formed in the surrounding wall portion 12 due to the formation of the recess 13, and the claw 14 Space can be secured on the back side of the.

取付凹部１１の底面１１ａ及び窪み１３にはシボ加工が施された上で、反射膜（アルミニウム等の金属蒸着膜）が成膜されている。囲い壁部１２にも反射膜が成膜されていてもよい。   The bottom surface 11a and the recess 13 of the mounting recess 11 are subjected to a textured process, and a reflective film (a metal deposition film such as aluminum) is formed. A reflective film may also be formed on the surrounding wall portion 12.

保持部材１０は再帰反射板２０を取付凹部１１内に保持するものである。再帰反射板２０が取付凹部１１の形状と同じ形状に形作られている。その再帰反射板２０が取付凹部１１の底面１１ａに対向するようにして取付凹部１１に嵌め込まれている。   The holding member 10 holds the retroreflective plate 20 in the mounting recess 11. The retroreflective plate 20 is formed in the same shape as the mounting recess 11. The retroreflective plate 20 is fitted into the mounting recess 11 so as to face the bottom surface 11 a of the mounting recess 11.

再帰反射板２０の裏側の面には、複数の再帰反射素子（例えば、コーナーキューブ）２１が形成されている。なお、再帰反射板２０の再帰反射原理はコーナーキューブを利用したものに限るものではない。例えば複数のガラスビーズが板状の基材の表側の面又は裏側の面に塗布されて付着されたものでもよいし、再帰反射シートが複数の板状の基材の表側の面又は裏側の面に貼り付けられたものでもよい。   A plurality of retroreflective elements (for example, corner cubes) 21 are formed on the back surface of the retroreflective plate 20. The retroreflective principle of the retroreflective plate 20 is not limited to that using a corner cube. For example, a plurality of glass beads may be applied and attached to the front side surface or the back side surface of the plate-like base material, or the retroreflective sheet may be a front side surface or a back side surface of the plurality of plate-like base materials. It may be pasted on.

再帰反射板２０の裏側の面のうち縁寄りの部位には、フック２２が形成されている。フック２２には、外方へ開口した嵌合凹部２３が形成されている。更に、フック２２のうち嵌合凹部２３よりも先端寄りの部位には、外方へ突出した突起２４が形成されている。   A hook 22 is formed at a portion near the edge of the back side surface of the retroreflective plate 20. The hook 22 is formed with a fitting recess 23 that opens outward. Further, a protrusion 24 protruding outward is formed in a portion of the hook 22 closer to the tip than the fitting recess 23.

フック２２が再帰反射板２０の裏側の面から後方へ突出し、フック２２の先端部位が窪み１３に入り込んで、そのフック２２が爪１４に引っ掛かっている。つまり、フック２２の嵌合凹部２３が爪１４に対応した形状に形成されており、爪１４が嵌合凹部２３に嵌め込まれ、突起２４が爪１４の裏側において爪１４に当接する。フック２２が爪１４に係止することによって再帰反射板２０が取付凹部１１に固定される。   The hook 22 protrudes rearward from the back surface of the retroreflective plate 20, the tip portion of the hook 22 enters the recess 13, and the hook 22 is hooked on the claw 14. That is, the fitting recess 23 of the hook 22 is formed in a shape corresponding to the claw 14, the claw 14 is fitted into the fitting recess 23, and the protrusion 24 abuts on the claw 14 on the back side of the claw 14. The retroreflective plate 20 is fixed to the mounting recess 11 by the hook 22 engaging with the claw 14.

再帰反射板２０の表側から再帰反射板２０に入射した光の殆どは再帰反射板２０によって再帰反射される。
再帰反射板２０の表側から再帰反射板２０に入射した光の一部が再帰反射板２０を透過する。取付凹部１１の底面１１ａ及び窪み１３がシボ加工されているので、再帰反射板２０を通過した光が取付凹部１１の底面１１ａ及び窪み１３によって乱反射される。その乱反射された光は再帰反射板２０を通過する。よって、窪み１３の像（窪み１３に形成された僅かな陰の像）が再帰反射板２０の表面に非常にぼけて映る。つまり、再帰反射板２０越しに取付凹部１１の底面１１ａを見ても、窪み１３やそれによる陰を視認しにくく、窪み１３と底面１１ａを識別しにくい。従って、再帰反射装置１の見栄えが向上する。 Most of the light incident on the retroreflective plate 20 from the front side of the retroreflective plate 20 is retroreflected by the retroreflective plate 20.
A part of the light incident on the retroreflective plate 20 from the front side of the retroreflective plate 20 is transmitted through the retroreflective plate 20. Since the bottom surface 11 a and the recess 13 of the mounting recess 11 are textured, the light that has passed through the retroreflective plate 20 is irregularly reflected by the bottom surface 11 a and the recess 13 of the mounting recess 11. The irregularly reflected light passes through the retroreflective plate 20. Therefore, the image of the depression 13 (a slight shadow image formed in the depression 13) appears very blurred on the surface of the retroreflective plate 20. That is, even when the bottom surface 11a of the mounting recess 11 is seen through the retroreflecting plate 20, it is difficult to visually recognize the recess 13 and the shade caused thereby, and it is difficult to identify the recess 13 and the bottom surface 11a. Therefore, the appearance of the retroreflective device 1 is improved.

保持部材１０が薄く、取付凹部１１が浅いと、爪１４を形成すべく、取付凹部１１の底面１１ａに窪み１３を形成せざるを得ない。そのような場合にも、底面１１ａ及び窪み１３のシボ加工は窪み１３を目立たせなくするのに有効である。窪み１３を目立たせなくしつつ、窪み１３の形成によって保持部材１０を薄くすることができるので、見栄えの良い再帰反射装置１の裏側にスペースを確保することができる。よって、再帰反射装置１を車両用灯具と組み合わせて用いる際に、車両用灯具の各種部品を再帰反射装置１の裏側に設置することができる。   If the holding member 10 is thin and the mounting recess 11 is shallow, the depression 13 must be formed on the bottom surface 11 a of the mounting recess 11 in order to form the claw 14. Even in such a case, the embossing of the bottom surface 11a and the depression 13 is effective to make the depression 13 inconspicuous. Since the holding member 10 can be thinned by forming the recess 13 while making the recess 13 inconspicuous, a space can be secured on the back side of the retroreflective device 1 having a good appearance. Therefore, when the retroreflective device 1 is used in combination with the vehicular lamp, various parts of the vehicular lamp can be installed on the back side of the retroreflective device 1.

なお、本発明を適用可能な実施形態は、上述した実施形態に限定されることなく、本発明の趣旨を逸脱しない範囲で上述した実施形態から変更可能である。
例えば、爪１４は反射膜によって被覆されていているか、シボ加工された上で反射膜によって被覆されていてもよい。 The embodiment to which the present invention is applicable is not limited to the above-described embodiment, and can be changed from the above-described embodiment without departing from the spirit of the present invention.
For example, the nail | claw 14 may be coat | covered with the reflecting film, or may be covered with the reflecting film after carrying out the embossing process.

また、再帰反射装置１が車両用灯具に組み込まれたものではなく、車両用灯具とは別に車両に取り付けられてもよい。つまり、保持部材１０が車両用灯具の部品９９と別に成型されたでもよい。   Further, the retroreflective device 1 is not incorporated in the vehicle lamp, and may be attached to the vehicle separately from the vehicle lamp. That is, the holding member 10 may be molded separately from the vehicle lamp component 99.

また、再帰反射装置１の用途は自動車に限るものではない。例えば、自転車の後部を表示する表示器、各種信号や警告を表示する表示器等に再帰反射装置１を利用することができる。   Moreover, the use of the retroreflection apparatus 1 is not limited to an automobile. For example, the retroreflective device 1 can be used for a display that displays the rear part of a bicycle, a display that displays various signals and warnings, and the like.
