Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a windshield lighting device attached to a motorcycle, such as a motorcycle, scooter, or motorized bicycle.

[Conventional technology]

Like bicycles, the driver of a motorcycle is directly exposed to the wind and rain, so a motorcycle is known in which a windshield 2 is attached to the front of the vehicle body 1 to protect the driver from the wind and rain, as shown in FIG.

[Problem that the invention attempts to solve]

However, because this type of two-wheeled vehicle is smaller than a general automobile and has fewer lighting devices due to its structure, it is less noticeable, especially when driving at night, and may be involved in an unexpected accident. Furthermore, traffic accidents involving two-wheeled vehicles are much more life-threatening than those involving automobiles, and extreme caution is required when driving. However, there is insufficient consideration given to the safety of the vehicle body itself, and there is a demand for a structure that is easy for drivers of other vehicles to notice from a distance, especially when driving at night.

Therefore, the present invention aims to solve the above-mentioned drawbacks and provide a windshield illumination device for two-wheeled vehicles that can be easily noticed from a distance by drivers of other vehicles when driving at night, and can prevent accidents. be.

[Means for solving problems]

In order to achieve the above object, the present invention arranges a pair of left and right light guides, each formed into a rod-shaped body, along each side edge of the windshield, and the lower end surface of each light guide is placed at the light entrance area. A light output portion is provided on the peripheral surface, and a light source is arranged corresponding to the light input portion of each light guide.

[Effect]

In the present invention, when driving at night, the light that enters each light guide body from the light input portion is emitted to the outside from the light output portion, thereby making the light output portion shine.

〔Example〕

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

Fig. 1 is a perspective view of an embodiment of the windshield lighting device according to the present invention as seen from the front of the vehicle, Fig. 2 is a perspective view of the same device as seen from the rear of the car, and Figs. FIG. In these figures, 4 and 5 are a pair of left and right light guides arranged along both edges of the surface of the windshield 2, and 6 and 7 are lights for illuminating the light guides 4 and 5 when driving at night, etc. A pair of left and right light sources 8 and 9 are lamp cases that house the light sources 6 and 7.
It constitutes 0.

The windshield 2 is formed into a plate shape from a transparent or appropriately colored translucent resin material such as polycarbonate or acrylic resin, and its lower end is installed on the handle of a two-wheeled vehicle (not shown). It is fixed to the windshield mounting plate 11. Among the peripheral edges of the windshield 2, especially the upper edge 2a and the left and right edges 2b, 2
c has a circular cross-sectional shape as shown in FIG. 4 to increase the strength and rigidity of the windshield 2, and the light guides are provided on the front side circumferential surface of the vehicle body on both left and right edges 2b and 2c. 4 and 5 are respectively disposed with spacers 13 interposed therebetween, and are each fixed by a plurality of set springs 14, at least two set springs 14.

Each of the light guides 4 and 5 is made of a resin material such as acrylic resin that is transparent and has excellent reflective properties, and is formed into a rod-shaped body with a circular cross section, and its lower ends 4A and 5A are located on both sides of the windshield mounting plate 11. It is guided to the back side of the mounting plate 11 through insertion holes 15 and 16 provided at the ends. Further, these lower end portions 4A, 5A are further inserted into the lamp cases 8, 9, which are respectively fixed to both sides of the back surface of the windshield mounting plate 11, and the end surfaces thereof face the light sources 6, 7. These form light entrance portions 18 and 19 (19 is not shown). When each of the light sources 6 and 7 is turned on, the light 20 enters into the light guides 4 and 5 from the light entrance portions 18 and 19, respectively.

In this case, if the circumferential surface of each light guide 4, 5 is mirror-finished, the light 20 incident on the light guide 4, 5 can be
progresses through repeated total reflection on its inner surface,
The light is emitted to the outside only from the upper end surface of each light guide 4,5. In other words, only the upper end surface is illuminated. Therefore,
In the present invention, a light emitting part 22 is formed on the circumferential surface of each of the light guides 4 and 5, and light 22 is emitted from the light emitting part 22.
By emitting 0 to the outside, each light guide 4,
5 is illuminated over almost its entire length.

The light emitting portion 22 is formed in the remaining portion of each light guide 4, 5 excluding the lower end portions 4A, 5A, that is, the portion located on the front side of the windshield 2, and various methods can be used for forming the light emitting portion 22. An example of this is shown in FIG. (in some cases, all around)
frosted or textured to create minute irregularities 2
5, the same figure b shows a tape 26 made of white or the like having excellent reflective properties attached to the circumferential surface of the light emitting part 22 on the side opposite to the direction in which the light 20 is to be emitted. In c, a reflective film layer 27 is formed by printing or painting on the circumferential surface of the light emitting portion 22 on the side opposite to the direction in which the light 20 is desired to be emitted. In this case, the part where the tape 26 is attached and the reflective film layer 2
The surface of the light guide at the portion where 7 is formed constitutes a very fine diffused reflection surface, similar to the unevenness 25 due to the texture processing, and diffusely reflects the light 20.

FIG. 5d shows an example in which a groove 28 is formed on the circumferential surface of the light emitting part 22 in the axial direction of the light guide 4, and the light 20 traveling inside the light guide 4 hits the wall of the groove 28 and is reflected. The wall is illuminated by emitting it to the outside. FIGS. 5e and 5f show an example in which the light emitting part 22 is formed discontinuously by stipples 30 and scratches 31, which are small V-shaped recesses formed on the circumferential surface of the light emitting part 22.
In this case, it goes without saying that the light emitting portion 22 may be discontinuously formed using the tape 26, the reflective film layer 27, and the like.

The spacer 13 is made of an elastic material such as rubber, and has semicircular fitting grooves 33 and 34 formed over its entire length on its front and rear surfaces as shown in FIG. The grooves 33 and 34 are provided with the side edges 2b and 2c of the windshield 2 and the light output portions 2 of the light guides 4 and 5.
2 and 23 are respectively fitted and fixed with adhesive or the like.

The set spring 14 that fixes the light guides 4 and 5 to the windshield 2 is usually formed in a C-shape from a metal plate. , an opening 35 may be provided as shown in FIG. 6, or the set spring 14 itself may be made of a transparent resin material.

In the windshield illumination device 10 having such a configuration, when each of the light sources 6 and 7 is turned on, the light 20 enters the light guide from the light entrance part 18 of each of the light guides 4 and 5, and is completely absorbed inside the light guide. The light propagates while being reflected and is emitted from the light emitting section 22 to the outside. As a result, the light output section 22
The light shines brightly, making it possible for drivers of other vehicles to clearly recognize the presence of your vehicle even from a distance when driving at night. Therefore, safety during night driving is improved and accidents are prevented. Furthermore, if the left and right end portions of the windshield 2 appear shiny, the design will be novel and the added value of the motorcycle will increase.

Although the above embodiment shows an example in which the light guides 4 and 5 have a circular cross-sectional shape, the present invention is not limited to this in any way, and the present invention may be used with an appropriate cross-sectional shape such as an ellipse. It is possible to fully achieve the purpose of the invention.

[Effect of idea]

As explained above, according to the windshield illumination device according to the present invention, both edges of the windshield can be seen shining, making it easy to see from a distance when driving at night, thereby improving safety. Also,
It has a simple structure, a good design and appearance, and has great practical effects such as improved fashionability.
