Abstract

PROBLEM TO BE SOLVED: To provide a thrust-through type meter pointer emitting light over the entire length thereof even in the night. SOLUTION: A pointer main body 10 is attached to a pointer cap 2 so as to thrust through the cap in the diameter direction thereof and the base end part of a light pervious member 11 is bent downwardly along the peripheral surface of the pointer cap and subsequently folded back into the indicator cap 2 to be penetrated into the cap and further bent downwardly to form a stepwise light guide part 20 and a light cutting-off coating film 13 having the same color as the colored coating film on the rear surface of the light pervious member 11 is formed on the outside peripheral surface of the pointer cap 2 of the light guide part.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pointer cap driven on a dial in accordance with a measured amount, and a pointer body supported by the pointer cap and having a colored coating formed on the back surface of a transparent body. The present invention relates to a meter pointer having a main body that emits light by illuminating light received by a light guide portion in a pointer cap formed integrally with a light transmitting body.

[0002]

2. Description of the Related Art FIG. 4 shows a meter pointer of this kind. A pointer cap 2 driven on a dial 1 in accordance with a measured amount, and a light transmitting member 3a supported by the pointer cap.
Is provided with a pointer body 3 having a colored coating film 3b formed on the back surface thereof. In the pointer cap 2, a light guide 8 is formed integrally with the light transmitting body 3a. The dial 1 is provided with a light projecting section 7 for guiding the light emitted from the lamp 7a by a light transmitting body 7b, corresponding to the movement path of the lower end 8a serving as the light receiving section. The light transmitting body 3a is of a penetrating type in order to penetrate the pointer cap 2 in the diameter direction, but a portion penetrating is formed thin because it is not guided backward, so that the inside cannot be seen.
On the surface, a coating film 3c of the same color as the colored coating film 3b is formed. As a result, the light incident on the light transmitting body 3a is reflected by the colored coating film 3b and causes the pointer main body 3 to emit light.

[0003]

Therefore, in the daytime, a pointer having a long coating color penetrates the pointer cap, but at night, the portion of the coating 3c does not emit light and looks short.

SUMMARY OF THE INVENTION In view of the foregoing, it is an object of the present invention to provide a through-type meter pointer that emits light at full length even at night.

[0005]

In order to achieve this object, the present invention provides a pointer cap which is driven on a dial in accordance with a measured amount, and has a colored coating film on the back surface of a transparent body. The pointer main body is formed, and the light transmitting body is made to emit light by the light emitting part provided on the dial corresponding to the movement path of the light guide part formed integrally with the light transmitting body in the pointer cap. In the meter pointer, the pointer body is attached to the pointer cap so that it penetrates in the diameter direction, the base end portion of the light transmitting body is bent downward along the peripheral surface of the pointer cap, and then folded back into the pointer cap to enter. It is formed as a stepped light guide that is bent downward, and a light-shielding coating of the same color as the colored coating on the back surface of the light-transmitting body is formed on the outer surface of the light guide outside the pointer cap. I do.

At night, the illuminating light enters the light transmitting body via the light guide, and illuminates the entire length of the pointer main body across the pointer cap.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A meter pointer according to an embodiment of the present invention will be described with reference to FIGS. The same reference numerals as those in FIG. 4 indicate the same or equivalent parts. Meter pointer 19
The pointer main body 10 is formed by forming, for example, a green colored coating film 12 on the back surface of the light transmitting body 11, and is mounted on the pointer cap 2 so as to penetrate in the diameter direction thereof. The base end portion of the light transmitting body 11 is bent downward along the peripheral surface of the pointer cap 2, then folded back into the pointer cap 2 to be penetrated, and further bent downward, the vertical portion 21 outside the cap and the horizontal portion 22. And a stepped light guide section 20 composed of the vertical section 23 in the cap.

Each corner portion of the light guide portion is chamfered so as to form a reflection surface for guiding illumination light incident from below to the translucent member 11, and the peripheral surface outside the pointer cap 2 is colored green. The coating film 13 is formed. The reflective coating 14 is also formed on the corner portion in the cap.

The lower end portion 25 serving as a light receiving portion of the light guide portion 20 has
The illumination light of the light projecting unit 7 formed corresponding to the arc-shaped movement path is received. As a result, the illumination light is incident on the light transmitting body 11 while being reflected at each corner of the light guide section 20 at night, and the entire length of the pointer main body 10 emits green light. The colored coating film 13 prevents light leakage in a portion of the pointer main body 10 other than the needle shape.

[0010]

As described above, according to the present invention, the entire length of the pointer shines at night by protruding further from the top of the pointer cap, thereby improving the design of the penetration type. The flexibility of the length of the needle is also widened, and the glow in a long range improves night visibility.

Claims (1)

[Claims] 1. A pointer body supported by a pointer cap driven on a dial in accordance with a measured amount and having a colored coating formed on a back surface of the light transmitting body, and integrated with the light transmitting body in the pointer cap. In a meter pointer adapted to emit light through a light-transmitting member by a light-transmitting portion provided on a dial corresponding to a movement path of a light-guiding portion formed at a position, the pointer main body penetrates a pointer cap in a diameter direction thereof. The base end portion of the light transmitting member is bent downward along the peripheral surface of the pointer cap, and then is folded back into the pointer cap to form a stepped light guide portion bent further downward, A meter pointer, wherein a light-shielding coating of the same color as the colored coating on the rear surface of the light-transmitting member is formed on a peripheral surface of the light guide portion outside the pointer cap.
