本発明のスイッチの照明機構を適用したスイッチ装置の実施形態を添付図面を参照して説明する。図１はスイッチ装置１の正面図、図２は図１に於けるＡ−Ａ線断面図である。スイッチ装置１のコントロールパネル２には、ハザードスイッチ３及びデフロスタスイッチ４及びエアコンスイッチ５が組み込まれている。また、吹出しモード切替用のロータリノブ６、ブロアスイッチのロータリノブ７及び温度調節用のロータリノブ８が横一列に設けられている。そして、各ロータリノブ６、７及び８の外周部に、円弧状のライトガイド９、１０、１１が配設され、コントロールパネル２の表面に現れている。 An embodiment of a switch device to which a switch illumination mechanism of the present invention is applied will be described with reference to the accompanying drawings. 1 is a front view of the switch device 1, and FIG. 2 is a cross-sectional view taken along line AA in FIG. The control panel 2 of the switch device 1, a hazard switch 3 and defroster switch 4 and the air conditioner switch 5 is incorporated. Further, a rotary knob 6 for switching the blowing mode, a rotary knob 7 for a blower switch, and a rotary knob 8 for temperature adjustment are provided in a horizontal row. Arc-shaped light guides 9, 10, 11 are arranged on the outer peripheral portions of the rotary knobs 6, 7, and 8 and appear on the surface of the control panel 2.

上記スイッチの照明機構は、円弧状のライトガイド９、１０、１１、照明ランプ１２を取り囲む半球形状部１３、該半球形状部１３から放射状に突成した直線状のライトガイド部１４等から構成されている。各円弧状のライトガイド９、１０、１１は、コントロールパネル２の裏面に於いて、照明ランプ１２を取り囲む半球形状部１３から放射状に突成した直線状のライトガイド部１４と連結されている。半球形状部１３は、吹出しモード切替用のロータリノブ６とブロアスイッチのロータリノブ７の間及びブロアスイッチのロータリノブ７と温度調節用のロータリノブ８の間に配置されている。ハザードスイッチ３の下面に位置する半球形状部１３は、上部に導光壁１３ａを設けた開口１３ｂが形成されている。また、デフロスタスイッチ４の下面には、該半球形状部１３から放射状に突成した直線状のライトガイド部１４の端部１４ａが対応している。 The illumination mechanism of the switch is composed of arc-shaped light guides 9, 10, 11, a hemispherical portion 13 surrounding the illumination lamp 12, a linear light guide portion 14 projecting radially from the hemispherical portion 13, and the like. ing. Each arc-shaped light guide 9, 10, 11 is connected to a linear light guide portion 14 projecting radially from a hemispherical portion 13 surrounding the illumination lamp 12 on the back surface of the control panel 2. The hemispherical portion 13 is disposed between the rotary knob 6 for switching the blowing mode and the rotary knob 7 for the blower switch, and between the rotary knob 7 for the blower switch and the rotary knob 8 for temperature adjustment. The hemispherical portion 13 located on the lower surface of the hazard switch 3 has an opening 13b provided with a light guide wall 13a in the upper portion. Further, the lower surface of the defroster switch 4 corresponds to an end portion 14 a of a linear light guide portion 14 projecting radially from the hemispherical portion 13.

ハザードスイッチ３及びデフロスタスイッチ４は、共に同一の構造の押圧スイッチである。従って、ハザードスイッチ３についてその構造を説明する。スイッチ筺体３１内には、押圧操作ノブ３２の押圧操作によりスイッチングされるスイッチ構成部３３が配設されている。押圧操作ノブ３２は、筒状部３４をスイッチ筺体３１に挿入するとともに、スイッチ構成部３３の外周に嵌挿されて摺動可能となっている。また、押圧操作ノブ３２の前面の押圧操作面３２ａには、有色透光性のマーク表示３５が形成されている。 The hazard switch 3 and the defroster switch 4 are both pressing switches having the same structure. Therefore, the structure of the hazard switch 3 will be described. A switch component 33 that is switched by a pressing operation of the pressing operation knob 32 is disposed in the switch housing 31. The pressing operation knob 32 is slidable by inserting the cylindrical portion 34 into the switch housing 31 and being inserted into the outer periphery of the switch constituting portion 33. A colored translucent mark display 35 is formed on the pressing operation surface 32 a on the front surface of the pressing operation knob 32.

さらに、スイッチ筺体３１の下面には、ライトガイドの半球形状部１３の開口１３ｂに対応する照明ランプ光の導入口３６が形成されている。該導入口３６に対応して押圧操作ノブ３２の筒状部３４にも、開口３４ａが形成されている。そして、導入口３５及び開口３４ａから導入された照明ランプ光を反射させて、押圧操作ノブ３２のマーク表示３５を照明する反射面３７が、図２に示すように該導入口３５及び開口３４ａに対応させてスイッチ構成部３３に配設されている。 Furthermore, an introduction port 36 for illumination lamp light corresponding to the opening 13 b of the hemispherical portion 13 of the light guide is formed on the lower surface of the switch housing 31. An opening 34 a is also formed in the cylindrical portion 34 of the pressing operation knob 32 corresponding to the introduction port 36. A reflecting surface 37 that reflects the illumination lamp light introduced from the introduction port 35 and the opening 34a to illuminate the mark display 35 of the pressing operation knob 32 is formed on the introduction port 35 and the opening 34a as shown in FIG. Correspondingly, they are arranged in the switch component 33.

上記スイッチの照明機構を適用したスイッチ装置１は、照明ランプ１２が点灯すると半球形状部１３及び直線状のライトガイド部１４により照明ランプ光がカイドされ、該ライトガイド部１４及び円弧状のライトガイド９〜１１が照明される。また、ハザードスイッチ３は、半球形状部１３の開口１３ｂからの照明ランプ光が、導入口３６及び開口３４ａから導入されて反射面３７で反射し、マーク表示３５を照明する。マーク表示３５は有色透光性であるから、該マーク表示３５に導かれた照明ランプ光を所定の色彩で視認することができる。同様に、デフロスタスイッチ４も、ライトガイド部１４の端部１４ａからの照明ランプ光がマーク表示４５に導かれて、所定の色彩で視認することができる。従って、ハザードスイッチ３及びデフロスタスイッチ４にそれぞれ照明ランプ１２を配設する必要がない。また、ライトガイドは、半球形状部１３から直線状のライトガイド部１４が突成されているから、該照明ランプ光を他のマーク表示等の照明光として利用できる。 In the switch device 1 to which the illumination mechanism of the switch is applied , the illumination lamp light is guided by the hemispherical portion 13 and the linear light guide portion 14 when the illumination lamp 12 is lit, and the light guide portion 14 and the arc-shaped light guide are guided. 9-11 are illuminated. Further, the hazard switch 3 illuminates the mark display 35 by illuminating lamp light from the opening 13 b of the hemispherical portion 13 being introduced from the introduction port 36 and the opening 34 a and reflected by the reflecting surface 37. Since the mark display 35 is colored and translucent, the illumination lamp light guided to the mark display 35 can be visually recognized with a predetermined color. Similarly, the defroster switch 4 can also visually recognize the illumination lamp light from the end portion 14a of the light guide portion 14 to the mark display 45 in a predetermined color. Therefore, it is not necessary to provide the illumination lamp 12 in each of the hazard switch 3 and the defroster switch 4. Further, since the light guide has a linear light guide portion 14 protruding from the hemispherical portion 13, the illumination lamp light can be used as illumination light for other mark display or the like.

上記説明により明らかなように、照明ランプ１２を取り囲む半球形状部１３と、該半球形状部１３から直線状のライトガイド部１４を突成してなるライトガイドを配置し、半球形状部１３の一部を切り欠いて照明ランプ光を直接ハザードスイッチ３に形成した導入口３６及び押圧操作ノブ３２の開口３４ａからスイッチ筺体３１内に導入する。そして、直線状のライトガイド部１４により照明ランプ光をデフロスタスイッチ４に導いて、導入口３６からスイッチ筺体３１内に導入し、導入口３６に配設した反射面により反射させて、押圧操作ノブ３２の裏面を照射し、各押圧操作ノブ３２の前面に導いて視認できるもので、半球形状部１３と該半球形状部１３から突成した直線状のライトガイド部１４を用いて、一個の照明ランプ光を複数のスイッチにおいて共用することができる。 As is clear from the above description, a hemispherical portion 13 surrounding the illumination lamp 12 and a light guide formed by projecting a linear light guide portion 14 from the hemispherical portion 13 are arranged. The illumination lamp light is directly introduced into the switch housing 31 through the introduction port 36 formed in the hazard switch 3 and the opening 34a of the pressing operation knob 32 by cutting out the portion. Then, the illumination lamp light is guided to the defroster switch 4 by the linear light guide portion 14, introduced into the switch housing 31 from the introduction port 36 , reflected by the reflecting surface disposed in the introduction port 36 , and the pressing operation knob. The back surface of 32 is irradiated and led to the front surface of each pressing operation knob 32 so that it can be visually recognized. One illumination is made using the hemispherical portion 13 and the linear light guide portion 14 projecting from the hemispherical portion 13. The lamp light can be shared by a plurality of switches .
