【考案の詳細な説明】
本考案は、計器の指針照明装置に関するもので
ある。[Detailed Description of the Invention] The present invention relates to an instrument pointer illumination device.
最近、車両用などの計器は、夜間の視認性向上
のため、目盛板の照明だけではなく、指針自体を
透明なアクリル樹脂等で成型し、これに光を導
き、指針を光輝させる指針照明が行われるように
なつてきている。 Recently, in order to improve visibility at night, instruments such as those for vehicles are equipped not only with illumination on the scale plate, but also with pointer illumination, which is made of transparent acrylic resin, etc., and which guides light to make the pointer shine. This is becoming more common.
このような指針照明において、従来は、第1a
図および第1b図に示すように、文字板1の下を
光導板2とし、この光導板に直接光源(図示せ
ず)から光を照射し、指針3がこの光導板と相対
する中央受光部3aの全周において光を受け、こ
の受けた光を受光部に形成した複数の反射面4を
経て指針3の先端3bおよび後端3cに到達させ
るようにしている。 In such pointer illumination, conventionally, the 1st
As shown in the figure and FIG. 1b, a light guide plate 2 is provided below the dial 1, and light is directly irradiated onto the light guide plate from a light source (not shown), and the pointer 3 faces the light guide plate at the central light receiving part. Light is received around the entire circumference of the pointer 3a, and the received light is made to reach the tip 3b and rear end 3c of the pointer 3 via a plurality of reflective surfaces 4 formed in the light receiving section.
しかして、このような従来の指針照明において
は、指針軸5を隠しかつ光導板2からの光を受け
る指針受光部3aにおける光の漏れを防止するた
めに、指針キヤツプ6を指針受光部3aの上に冠
着しているため、指針3の先後端3b,3cのみ
しか光輝させることができず、したがつて指針全
体を光輝して視認性を高めることができない欠点
があつた。 However, in such conventional pointer illumination, in order to hide the pointer shaft 5 and prevent light leakage in the pointer light receiving section 3a that receives light from the light guide plate 2, the pointer cap 6 is placed above the pointer light receiving section 3a. Since it is crowned on top, only the front and rear ends 3b and 3c of the pointer 3 can be made to shine, and therefore the entire pointer cannot be made to shine to improve visibility.
また、従来の他の例として、第2図に示すよう
に、指針の先端のみを光輝させたものもあるが、
これも前述したと同様な欠点があつた。 In addition, as another conventional example, there is one in which only the tip of the pointer is made to shine, as shown in Figure 2.
This also had the same drawbacks as mentioned above.
本考案は、このような従来の欠点を除去し、指
針全体を光輝させることができるようにした指針
照明装置を提供するものである。 The present invention provides a pointer illumination device that eliminates these conventional drawbacks and allows the entire pointer to shine.
以下、第3a図および第3b図を参照して本考
案の一実施例について詳述する。 Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 3a and 3b.
第3a図および第3b図において、指針33は
指針主部33aと指針受光部33bとに分割さ
れ、周囲より導光部材である光導板32からの光
を受けるように指針軸35の先端に固着された指
針受光部33bは指針主部33aの中央部33c
の下面33eに嵌込まれている。そして、この指
針受光部33bは、その周囲より受けた光を順次
反射させて指針主部33aの先後端にまで導く反
射面33fを有する構造とされている。 In FIGS. 3a and 3b, the pointer 33 is divided into a pointer main part 33a and a pointer light receiving part 33b, and is fixed to the tip of a pointer shaft 35 so as to receive light from the light guide plate 32, which is a light guide member, from the surroundings. The pointer light-receiving section 33b is located at the central portion 33c of the pointer main section 33a.
It is fitted into the lower surface 33e of. The pointer light receiving section 33b has a structure having a reflecting surface 33f that sequentially reflects light received from its surroundings and guides it to the front and rear ends of the pointer main section 33a.
このような指針構造にすることにより、指針キ
ヤツプ36を図示するように指針受光部33bを
覆うようにして指針主部33aの嵌込部分33e
のまわりに取付けることができるので、指針軸3
5を隠しかつ光導板32からの光を受ける指針受
光部33bにおける光の漏れを防止しながら、指
針主部全体を光輝させることができ、したがつて
計器指針の視認性を一層高めることができる。 By adopting such a pointer structure, the fitted portion 33e of the pointer main portion 33a is arranged such that the pointer cap 36 covers the pointer light receiving portion 33b as shown in the figure.
Since it can be installed around the pointer shaft 3
5 and prevents light leakage in the pointer light receiving section 33b that receives light from the light guide plate 32, the entire main part of the pointer can be illuminated, and the visibility of the instrument pointer can therefore be further improved. .
また、第4図に示すように、指針主部33aと
指針受光部33bとの嵌込部を指針主部33aの
中央部33cの上面近くで曲面37にすることに
より、この曲面37で反射させた光の指針先端3
3d側への到達点を第3b図の場合よりも一層遠
くにすることができ、したがつて光の繰返し反射
による減衰をより少なくすることができる。 In addition, as shown in FIG. 4, by forming the fitting portion between the pointer main portion 33a and the pointer light receiving portion 33b into a curved surface 37 near the upper surface of the central portion 33c of the pointer main portion 33a, the light is reflected by this curved surface 37. Light pointer tip 3
The arrival point on the 3d side can be made further away than in the case of FIG. 3b, and therefore the attenuation due to repeated reflections of the light can be further reduced.
なお、上記の説明にあつては、指針に与えられ
る光を光導板32からとして説明したが、これは
光導板に限らず、文字板31が光導板を兼ねてい
るものであつても良いことは勿論である。 In addition, in the above explanation, the light given to the pointer was explained as being from the light guide plate 32, but this is not limited to the light guide plate, and the dial 31 may also serve as a light guide plate. Of course.
以上述べたように、本考案によれば、簡単な機
構でかつ何等特別の部品を使用することなく指針
全体を光輝させ、計器指針の視認性を一層向上さ
せることができるきわめて有益な指針照明装置が
提供される。 As described above, the present invention provides an extremely useful pointer illumination device that has a simple mechanism and can illuminate the entire pointer without using any special parts, further improving the visibility of the instrument pointer. is provided.
