Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a lighting device for a handlebar grip box of a motorcycle.

(Conventional technology) A motorcycle provided with a character part in a box provided near the handle grip and equipped with an operation switch
No. 64-55191 is known.

In addition, as a vehicle indicator light, there is known in Japanese Utility Model Application Laid-Open Publication No. 52-74777, a light guide using a fiberscope to irradiate light in different directions by one bulb.

(Problems to be Solved by the Invention) In a motorcycle, it is sometimes difficult to operate the operation switch of the handle grip box during driving at night, so it is desirable to provide a lighting device in the handle grip box. .

However, the conventional lighting device for a vehicle has a structure in which a reflecting plate and a light shielding plate are provided around a bulb, so that there is a problem that the size of the device is increased and the cost is increased.

The present invention has been made to solve the above-described problem, and an object of the present invention is to provide a handlebar box lighting device for a motorcycle which can effectively guide light to a character portion by a simple device. It is assumed that.

(Means for Solving the Problems) The present invention has been made to achieve the above-mentioned object, and the means is provided in a handle grip box of a motorcycle having a character portion and having a plurality of operation switches. A hole for an operation switch and a hole for a light guide member are provided in the box, and a hole for each operation switch and a plurality of types of translucent characters corresponding to each operation switch are provided on the front surface of the handle grip box. A transparent or translucent light guide member having a built-in light source and having a shape corresponding to the character portion is adhered behind the display plate. The light guide member is inserted into the hole of the handle grip box and attached, and the light guide member is made thicker as the light source section becomes thinner as the distance from the light source section increases, and the light guide section is subjected to surface treatment except for the light transmitting surface. It is characterized by being more opaque.

(Operation) With the above configuration, the light guide member is securely held in the hole of the handle grip box, and the light from the light source incorporated in the transparent or translucent light guide member is transmitted to the light guide member. Is transmitted to the light-transmitting surface on the average, and the entire light-transmitting surface has substantially uniform brightness, and the entire characters on the display panel provided with a plurality of types of character portions are proved to be bright.

Hereinafter, the present invention will be described in detail with reference to the drawings.

Is provided.

In order to form the light transmitting surface 4a, masking is applied to the front T-shaped surface, and the other than the light transmitting surface is made opaque by black coating or surface treatment such as vapor deposition. The masking is then removed.

The display plate 6 is made of an opaque thin plate, and corresponds to the hole 3a of the handle grip box 3, and has holes for a plurality of types of characters such as a tuning switch, a tape, and a mute switch.
6a are continuously provided, and further, a knob square hole 6b of the tuning switch 7 and a knob square hole 6c of the mute switch 8 are provided corresponding to the square holes 3b and 3c.

The handle grip box 3 is mounted by fitting the mounting projection 3d into the hole 2a on the switch unit 2.
The light guide member 4 has a light transmitting surface in the handle grip box 3.
4a is fitted into the hole 3a by the front of the mounting hole 4d.
Then, the transparent or translucent member 4 is provided on the switch unit 2 by the mounting screw 9. The valve 5 is housed in the hole 4c.

The thin display plate 6 is adhered to the front surface of the handle grip box 3 so as to be a light transmitting surface 4a corresponding to the hole 6a of the character portion.

The tuning switch 7 and the mute switch 8 are provided in the knob square holes 3b and 6b and the knob square holes 3c and 6c, respectively, to perform tuning and mute adjustment of the radio.

In the handlebar box lighting device for a motorcycle according to the present invention, when the bulb 5 serving as the light source emits light, the light from the bulb 5 is blackened or vapor-deposited on the outside together with the direct light transmission through the light-transmitting surface 4a. Due to the reflection and transmission of light from the concave surfaces 4b, the guide holes 6a of the character portion of the display panel 6 are evenly dispersed and guided to the hole 6a of the character portion of the display panel 6, whereby the hole 6a of the character portion of the display panel 6 is uniformly brightly illuminated.

In this way, the hole 21a in the character portion of the display panel 21 is proved to be bright.

Note that the present invention is not limited to each embodiment, and it goes without saying that the present invention can be applied to any box provided with a plurality of types of character portions provided near the handle.

(Effect of the Invention) The present invention has an advantage that the light guide member and the handle grip box are fixed after the light guide member is accommodated in the hole provided in the front surface of the handle grip box, so that the fixation is securely performed. is there. In addition, since the front surface of the light guide member is in close contact with the back surface of the opaque display panel except for the character portion, the characters are displayed brightly without light leakage. Furthermore, the light guide member is made thicker as the light source section becomes thicker and more distant from the light source section, and opaque except for the light transmitting surface, so that light is transmitted evenly and the entire light transmitting surface has substantially uniform brightness. Although the character portion of the display panel is of a wide range in which a plurality of types are continuously arranged corresponding to the number of switches, the whole character portion is illuminated brightly. Therefore, it is possible to provide a handlebar box lighting device for a motorcycle that can effectively guide light to a character portion by a simple device.
