Description

The present invention relates to a flasher lamp device for a motorcycle.

[Prior Art] Conventionally, a flasher lamp for a motorcycle has been conventionally attached to a tip end portion of an arm protruding left and right from a frame. As disclosed in Japanese Patent Laid-Open No. 58-56978, the flasher lamps tend to be a so-called built-on type in which the flasher lamps are integrally embedded in the left and right side surfaces of the cowling.

[Problems to be Solved by the Invention] By the way, the cowling is installed mainly for the purpose of reducing the air resistance by rectifying the flow of air flowing around the vehicle body while the motorcycle is traveling. Therefore, the flasher lamps attached to the left and right sides of the cowling are
If the cowling is greatly projected to the left and right sides, air resistance increases due to the presence of the flasher lamp, and the sense of unity between the flasher lamp and the cowling is impaired, which is not preferable in terms of appearance.

On the other hand, the flasher lamp has a function of showing the intention of the driver and the presence of the motorcycle to a third party, and displaying the running state of the motorcycle, and therefore it is necessary to provide the flasher lamp at a position where it is easy to confirm the lighting. is there.

Therefore, if the function of the cowling is prioritized, the flasher lamp becomes difficult to see, and conversely, if the presence of the flasher lamp is emphasized, conflicting problems such as increased air resistance and deterioration of appearance will occur. There is a need for measures to

The present invention has been made based on such a situation, and the light from the bulb is directed to the front and side of the cowling without waste while efficiently suppressing the amount of protrusion of the lamp body and the lens to the left and right sides. An object of the present invention is to provide a flasher lamp device for a motorcycle that can be guided well and that can reduce air resistance while maintaining good visibility when the bulb is lit.

[Means for Solving the Problems] In order to achieve the above object, a flasher lamp device of the present invention is provided with a cowling having substantially flat left and right side surfaces covering a front part of a vehicle body and attached to both left and right side surfaces of the cowling. The lamp body and the lamp body, which is provided by being recessed inside the cowling rather than the mounting portion to the cowling, the socket mounting portion to which the socket for supporting the bulb is mounted, and the socket mounting portion, While covering the valve from the rear,
An end portion of the vehicle body located on the outer side in the width direction is extended toward the outer side in the width direction of the vehicle body with respect to the bulb, and a reflection plate for reflecting the light from the bulb toward the front, and above and below the bulb. An auxiliary reflection plate that is arranged to reflect light traveling upward and downward of the bulb toward the reflection plate, and that covers the reflection plate, the auxiliary reflection plate, and the bulb continuously to the lamp body, and is positioned in front of the bulb. A front lens part, a lens having a side lens part located laterally of the bulb, and an outer edge shape that follows the outer shape of the lens when the cowling is viewed from the front, The lens is provided with a cover portion that extends rearward continuously from the lens, and a side surface of the cowling that is inclined so as to be continuous with both left and right side surfaces of the cowling as it extends rearward. It is characterized.

[Operation] With such a configuration, the socket mounting portion is provided at a position recessed inward of the cowling with respect to the lamp body, so that the amount of protrusion of the bulb and the reflector to the side of the cowling is reduced. . For this reason, it is possible to prevent the lens that covers the bulb and the reflector, including the lamp body, from greatly protruding to the side of the vehicle body, and the sense of unity between the flasher lamp and the cowling is improved.

Since the end of the reflector is extended outward of the bulb in the vehicle width direction, this reflector is extended from the socket mounting part that is recessed inward of the cowling. Becomes longer. Therefore, the reflector itself can be increased in size, and the area of the reflector can be sufficiently secured. Moreover, since the light directed to both the upper and lower sides of the bulb is guided to the reflector through the auxiliary reflector, the light from the bulb can be reflected forward without waste. Therefore, a large amount of light is directed to the front lens portion of the lens, and this light is guided to the outside through the front lens portion. Further, since this lens has not only the front lens portion but also the side lens portion, the light directed to the side of the bulb is guided to the side of the vehicle body through the side lens portion as it is.

Therefore, although the amount of protrusion of the bulb itself to the side of the cowling is reduced, the light from the bulb can be efficiently guided to the front and side of the vehicle body, and the visibility is improved accordingly.

Also, since the rear end of the lens is smoothly connected to the side surface of the cowling due to the presence of the cover, a large step is not formed between the rear end of the lens and the side surface of the cowling. As a result, the amount of protrusion of the lens toward the side of the vehicle body is reduced, and in addition, while the motorcycle is traveling, it is possible to prevent a large disturbance in the flow of the traveling wind from the side surface of the cowling to around the lens, and to improve the air resistance. Can be reduced.

[Embodiment] The present invention will be described below based on an embodiment shown in the drawings.

5 and 6 show a motorcycle, and a cowling 3 is fixed to the upper front end of the vehicle body 1 to cover the front fork 2 from the upper front to the left and right sides.

As shown in FIG. 6, the cowling 3 has left and right side surfaces 3a, 3b that are substantially flat.
The tank cover 5 is extended toward the side and forms a fuel tank. The tank cover 5 integrally covers the periphery of the air cleaner 7 and the fuel tank 8 installed above the engine 6.

From the both sides of the lower part of the seat 4 to the rear, a side cover 9 which also serves as a seat cowl is covered. The front end of the side cover 9 is integrally connected to the tank cover 5, and the rear end side is inclined upward as it goes rearward.

By the way, flasher lamps 10 according to the present invention are installed at four locations on the left and right side surfaces 3a, 3b of the cowling 3 and the rear end side surfaces 9a of the side cover 9, respectively. Since the flasher lamp 10 is common to the front, rear, left and right, the flasher lamp 10 on the left side surface 3a of the cowling 3 will be described with reference to FIGS. 1 and 3.

That is, reference numeral 11 in the figure is a lamp body made of synthetic resin and has a box shape elongated in the front-rear direction. The front half of the lamp body 11 is continuously opened in four directions of front, upper, lower and left sides, and a lens 13 is detachably fitted in the opening 12. Lens 13
The front lens portion 13a facing the front of the vehicle body 1 and the side lens portion 13b facing the side of the vehicle body 1 continuously from the front lens portion 13a are provided. A light emitting chamber 14 is formed in the front half of the.

A socket mounting portion 15 is formed on the bottom surface 14a of the light emitting chamber 14 so as to be recessed so as to enter the cowling 3 more than the left side surface 3a of the cowling 3. A socket 17 is attached to the bottom of the socket mounting portion 15. The socket 17 projects from the socket mounting portion 15 toward the inside of the cowling 3. This socket 17 has a valve 16
The bulb 16 is opposed to the front lens portion 13a and the side lens portion 13b in the light emitting chamber 14, respectively.

The lamp body 11 is fitted from the outside into a lower recess 18 formed on the left side surface 3a of the cowling 3. At this time, the lamp body 11 has a bolt 19 embedded at its rear end.
Through the bottom surface 18a of the recess 18 and tightened with the nut 20 from the inside of the cowling 3, and the front end of the lens 13
Cowling 3 by tightening together with screws 21
It is embedded and fixed in one piece.

The lamp body 11 is fixed to a horizontal line X1-X1 extending in the front-rear direction of the vehicle body 1 such that the lamp body 11 is inclined forward by a predetermined angle so as to be positioned downward as it advances forward, and the front surface of the lens 13 is inclined. It is pointing downwards.

Further, the rear half of the lamp body 11 is provided with a cover portion 11a continuously extending rearward from the rear end of the lens 13. As shown in FIG. 2, the cover portion 11a has an outer edge shape that follows the outer shape of the lens 13 when the flasher lamp 10 is viewed from the front, and the cover portion 11a has a surface on the left side of the vehicle body 1. The side surface 11b is inclined toward the left side surface 3a of the cowling 3 as it goes backward. Therefore, the cover portion 11a of the lamp body 11 smoothly connects the rear end of the lens 13 and the left side surface 3a of the cowling 3.

Inside the light emitting chamber 14 of the lamp body 11, there is arranged a reflection plate 22 for mainly reflecting the light emitted from the bulb 16 forward. The reflector 22 is a tongue piece 22a for mounting.
And a reflecting mirror portion 22b connected to the tongue piece 22a, and the tongue piece 22a is supported by the bottom portion of the socket mounting portion 15. The reflecting mirror portion 22b is located behind the bulb 16 without covering the bulb 16 from the side, and the end portion of the reflecting mirror portion 22b located outside in the vehicle width direction is the first
As shown in the figure, the valve 16 is extended outward in the vehicle width direction.

As shown in FIG. 3, the reflecting mirror portion 22b is curved in a substantially arcuate shape and is tilted upward by a certain angle with respect to the center line O1-O1 of the lamp body 11 which is tilted forward. The light emitted from the bulb 16 is reflected substantially horizontally toward the front front lens portion 13a by this inclination.

In such a reflector 22, the reflectors 22b are inclined in opposite directions on the left side and the right side of the vehicle body 1, that is, on the right side, they are inclined downward by a certain angle with respect to the center line O1-O1. Therefore, two types of reflectors 22 are prepared, one for the left side and one for the right side, and are selectively attached to the socket attachment portion 15 according to the left and right installation positions of the lamp body 11.

A pair of auxiliary reflectors 23, 23 are installed in the light emitting chamber 14. These auxiliary reflectors 23, 23 reflect light directed upward and downward of the bulb 16 toward the reflection mirror portion 22b side and efficiently guide the light forward and sideward.

According to this structure, the socket mounting portion 15 of the lamp body 11 is located inside the cowling 3 more than the mounting portion of the lamp body 11 to the cowling 3, and therefore is supported by the socket 17 of the socket mounting portion 15. Also, the bulb 16 and the reflector 22 are also displaced inward in the vehicle width direction, and the amount of protrusion of the bulb 16 and the reflector 22 to the left and right sides of the cowling 3 is reduced.

Therefore, it is possible to prevent the lamp body 11 and the lens 13 from largely protruding to the side of the cowling 3, and the flasher lamp
The sense of unity between 10 and cowling 3 is improved.

In addition, the light from the bulb 16 is mainly transmitted to the front front lens part 13a.
Since the reflecting plate 22 that reflects toward the vehicle is extended outward of the bulb 16 in the vehicle width direction, the reflecting plate 22 extends from the socket mounting portion 15 that is recessed inward of the cowling 3, The reflecting mirror portion 22b can be formed long in the left-right direction. Therefore, the reflecting mirror portion 22b itself becomes large, and the area of the reflecting mirror portion 22b can be sufficiently secured.

At the same time, the auxiliary reflector 2
3, 23 are arranged, and the light directed to the upper and lower sides of the bulb 16 is reflected by the auxiliary reflectors 23, 23 toward the reflector 22. This front lens part 13a can be guided towards
The amount of light toward

The reflector 22 is located behind the bulb 16, and the side surface lens portion 13 of the lens 13 is located on the side of the bulb 16.
Since b is positioned, the light directed to the side of the bulb 16 is guided to the side of the vehicle body as it is through the side lens part 13b.

Therefore, although the amount of protrusion of the lamp body 11 and the lens 13 to the outer side in the vehicle width direction is small, the amount of light directed to the front and side of the cowling 3 is large and the flasher lamp
The visibility of 10 can be improved.

Moreover, the lamp body 11 includes the cover portion 11a extending rearward from the rear end of the lens 13, and the side surface 11b of the cover portion 11a.
Is the left and right side surfaces 3a, 3b of the cowling 3 as it goes backward.
Since it is inclined in the direction close to
By a, the lens 13 and the left and right side surfaces 3a, 3b of the cowling 3 can be smoothly continuous.

From this, the left and right side surfaces 3 of the lens 13 and cowling 3
Since there is no big step between a and 3b,
While the motorcycle is traveling, it is possible to prevent a large disturbance in the flow of traveling wind along the left and right side surfaces 3a, 3b of the cowling 3,
To that extent, there is an advantage that the air resistance can be reduced.

[Effect of the Invention] According to the present invention described in detail above, the positions of the bulb and the reflector supported by the socket are displaced to the inner side in the vehicle width direction, so that the amount of protrusion of the lamp body and the lens to the side of the vehicle body can be reduced. Therefore, the sense of unity between the flasher lamp and the cowling is improved. Also, since the reflector is extended to the outside of the bulb in the vehicle width direction, this reflector extends from the socket mounting part that is recessed inward of the cowling, so that the reflector becomes longer in the left-right direction. The size of the reflector itself can be increased. Therefore, the area of the reflector can be sufficiently secured, and most of the light from the bulb can be guided to the front lens portion.

Moreover, since the light directed to both the upper and lower sides of the bulb is guided to the reflector through the auxiliary reflector, it is possible to reflect the light from the bulb forward without waste, and the amount of light directed to the front lens portion of the lens is reduced. Will increase. Also, since this lens has not only the front lens part but also the side lens part,
Light that goes to the side from the bulb is guided as it is to the side of the vehicle body through the side lens portion.

Therefore, although the amount of protrusion of the bulb itself to the side of the cowling is small, the light from the bulb can be efficiently guided to the front and side of the vehicle body, and the visibility of the flasher lamp can be improved.

Moreover, since the cover allows the lens and the left and right side surfaces of the cowling to be smoothly connected to each other, a large step is not generated between the lens and the cowling, and the left and right side surfaces of the cowling are provided while the motorcycle is traveling. There is an advantage that a large turbulence is prevented from occurring in the flow of the traveling wind along and the air resistance can be reduced accordingly.
