## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
The present invention claims priority under 35 USC 119 based on Japanese patent application No. 2003-354253, filed Oct. 14, 2003.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a headlamp for a two-wheeled vehicle. More particularly, the present invention relates to headlamp for a motorcycle or similar vehicle.
2. Description of the Background Art
A headlamp for a two-wheeled vehicle is known which is provided on a front cowl. A headlamp for a two-wheeled vehicle of this type is disclosed, for example, in Japanese Patent No. 3343698.
FIG. 17, which corresponds to FIG. 6 of Japanese Patent No. 3343698 except the parts have been renumbered, is a front view showing a headlamp 302 for a two-wheeled vehicle in the related art. There is shown a two-wheeled vehicle in which a front portion of a vehicle body is covered by a front cowl 301 from the front of the vehicle body to the side of the vehicle body, and a headlamp 302 having an inverted trapezoidal shape is provided at the face of the front cowl 301. Further, an outside air introducing port 304 is also located at the face of the front cowl 301 and underneath the headlamp 302. A front wheel 303 is located underneath the outside air introducing port 304, such that the outside air introducing port 304 extends across a front wheel 303.
When operating the two-wheeled vehicle, the headlamp 302 is turned on for drawing the attention of other vehicles or pedestrians when travelling during the daytime as well as during the night time. Therefore, by improving the visibility of the headlamp 302, the efficiency of the headlamp 302 to draw other people's attention would also be improved.
In order to improve cooling performance, it is better to provide the outside air introducing port 304 below the front cowl 301, which allows traveling wind to blow onto an engine, a radiator, or the like. Further, it is better to arrange the headlamp 302 above the front cowl 301 in order to illuminate the front side of the vehicle. In this manner, the shape of the front cowl 301 is limited due to the aforementioned headlamp 302, the outside air introducing port 304, and the like.
In addition, the headlamp 302 is an important element for determining a design of the front portion of the two-wheeled vehicle, and hence it is desired to have a shape which gives a novel impression.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a headlamp for a two-wheeled vehicle which increases flexibility in the design of a vehicle body cover provided on the front portion of the vehicle while increasing visibility of the headlamp. The flexibility in the design is achieved through the shape of the headlamp, thus also giving a novel impression.
According to a first aspect of the present invention a two-wheeled vehicle is provided with a vehicle body cover at the front of the vehicle and a headlamp mounted to the vehicle body cover, wherein the headlamp includes and elongated portion extending in the lateral direction of the vehicle and portions extending downwardly from both ends of the laterally extending portion.
In the related art, a vehicle body cover is shaped in such a manner that will support a round or a rectangle headlamp. However, according to the first aspect of the present invention, the shape of the vehicle body cover employed is such that a headlamp is provided with a laterally extending segment which has segments extending vertically in a downward direction from each end of the laterally extending segment. Using this design for a headlamp will improve visibility of the headlamp by another vehicle or a pedestrian. In addition, the laterally extending portion and the downwardly extending portions give a novel impression as a headlamp. A shape for a vehicle body cover which may incorporate such a headlamp may include, for example, a vehicle body cover having an air intake port between the left and right downwardly extending portions of a headlamp.
Further, according to a second aspect of the present invention, a headlamp may be formed substantially into the shape of a letter H by extending portions in both an upward and a downward direction from both the ends of the laterally extending portion. This design will also improve the visibility of a headlamp by another vehicle or a pedestrian. The headlamp formed into the substantially H-shape also gives a favorable and novel impression.
According to a third aspect of the present invention, a headlamp may be formed such that the vehicle body cover is formed into an angular C-shape. With such vehicle body cover, the front surface of the vehicle body cover, above the bent portion of the angular C-shape, may be formed by an upper inclined section, the laterally elongated portion of the headlamp may be arranged on the upper inclined section of the angular C-shape and be allocated to be a portion for emitting a low beam, and the upward and downward vertically extending portions of the headlamp may be allocated to be portions for emitting high beams. By arranging the laterally extending portion in such a manner, the irradiating property from the laterally extending portion is improved.
According to a fourth aspect of the present invention, a headlamp may further include a vehicle body cover where the front surface below the bent section of the angular C-shape is formed by a lower inclined section, and the downward vertically extending portions of the headlamp may be extended from the upper inclined section to the lower inclined section.
The downward vertically extending portions of the headlamp may be extended from the upper inclined section to the lower inclined section of the cover so that the irradiating property from the vertically elongated lower extending portion is improved.
According to a fifth aspect of the present invention, a headlamp may be disposed along the edge of an opening provided on the front portion of the vehicle body cover having the same shape and size as the headlamp. Since the headlamp is formed along the edge of the opening provided at the front of the vehicle body cover, the shape and the size of the opening can hardly be limited in comparison with the case in which a round or square headlamp is disposed at the front of the vehicle, whereby the area of the opening can be increased, thereby improving cooling capability of the engine.
According to a sixth aspect of the present invention, a headlamp may comprise one or more LEDs as the main light emitting source, and may be formed into an M-shape or into an H-shape in front view of the two wheeled vehicle. The headlamp formed using an LED(s) desirably reduces the power consumption of the headlamp. Also, the headlamp formed into the M-shape or into the H-shape, again, gives a novel impression in appearance.
With the first aspect of the present invention, since the headlamp includes an elongated segment extending in a lateral direction and segments extending in a downward direction from both ends of the portion extending in a lateral direction, visibility of the headlamp especially during the daytime can be improved so as to more efficiently draw attention of other vehicles and pedestrians.
Moreover, since the shape of the vehicle body cover is different from the case in which a round or rectangular headlamp is used, because of the unique shape of the headlamp of the present invention, a vehicle body cover having an air intake port between the left and right segments of the headlamp which extend in a downward direction may be formed, reflecting that flexibility in design of the vehicle body cover is improved. In addition, since the headlamp includes segments extending both laterally and vertically, it can give a novel impression as a headlamp, whereby the commercial property of the two-wheeled vehicle can be improved.
With the second aspect of the present invention, the headlamp is formed into an H-shape by being vertically extended at opposite ends of the lateral portion both upwardly and downwardly. This design also gives a novel impression as the headlamp, whereby the commercial property of the two-wheeled vehicle can be improved.
With the third aspect of the present invention, the vehicle body cover is formed into an angular C-shape and positioned in such a way that the C-shape is apparent from the side view, the front surface of the vehicle body cover above the bent section of the angular C-shape is formed by an upper inclined section, the laterally extending portion of the headlamp is arranged on the upper inclined section, the portion extending in a lateral direction is allocated to be a portion for emitting a low beam and the headlamp portions extending in a vertical direction are allocated to be portions for emitting high beams. Therefore, the irradiating property from the portion extending in a lateral direction is improved, and hence the road surface can be illuminated more brightly.
With the fourth aspect of the present invention, the front surface of the vehicle body cover below the bent section of the angular C-shape is formed by the lower inclined section, and the headlamp portions extending vertically in a downward direction are extended from the upper inclined section to the lower inclined section. Further, a light beam is emitted from the vertically elongated portions which are extended upward and downward, thereby improving the irradiating property of the headlamp.
With the fifth aspect of the present invention, since the headlamp is formed along the edge of the opening provided at the front of the vehicle body cover, the shape and the size of the opening is hardly limited in comparison with the case in which a round or square headlamp is disposed at the front of the vehicle, whereby the area of the opening can be increased, thereby improving cooling capability of the engine.
Also, since the shape or the size of the opening needed for a headlamp according to the present invention is not limited as much as is case in which a round or square headlamp is disposed at the front of the vehicle as in the background art, the area of the opening in which the headlamp is disposed in the vehicle cover can be increased, thereby improving the cooling capability of the engine.
With the sixth aspect of the present invention, the headlamp comprises one or more LEDs as the main light emitting source, and is formed into an M-shape or into an H-shape when looking at the front view of the two wheeled vehicle.
Since the headlamp is formed using LED(s) the power consumption of the headlamp is desirably reduced in comparison to conventional headlamps. Further, the headlamp formed into the M-shape or the H-shape gives a favorable novel impression in appearance.
Although the following disclosure offered for public dissemination is detailed to ensure adequacy and aid in understanding the invention, this is not intended to prejudice that purpose of a patent which is to cover each new inventive concept disclosed therein no matter how it may later be disguised by variations in form or additions of further improvements. The claims appended hereto are intended as the chief aid towards this purpose, as it is the claims which meet the requirement of pointing out the improvements and combinations in which the inventive concepts are found.

Since the headlamp 73 includes a lateral portion 73a and vertical portions 73b elongated in a downward direction from the both ends of the lateral portion 73a, light may be emitted from the lateral portion 73a and the two portions 73b, hence improving the visibility of the headlamp 73 to other vehicles and to pedestrians, especially during the daytime.
Further, as shown in FIG. 16(b), the headlamp 73 of the present invention may be formed into an H-shape by extending the vertical portions 212 in both an upward and a downward direction from both ends of the lateral portion 73a. This H-shape design for the headlamp 73 can give a novel impression to the two-wheeled vehicle 10, whereby the commercial property of the two-wheeled vehicle 10 (see FIG. 1) can be improved.
Additionally, in the present invention the leg shield 27 may be formed into an angular C-shape in side view, wherein the front surface above the angular C-shaped bent section 27a of the leg shield 27 is formed by an upper inclined section 27b, with the laterally extending portion 73a of the headlamp disposed on the upper inclined section 27b, the lateral portion 73a being allocated for emitting a low beam, and the vertical portions 73b being allocated for emitting high beams.
Since the leg shield 27 is formed into an angular C-shape in side view, the lateral portion 73b is disposed on the upper inclined section 27b which constitutes the leg shield 27 which is of angular C-shape. Since the lateral portion 73a is allocated for emitting a low beam, and the vertical portions 73b are allocated for emitting high beams, the irradiating property from the lateral portion 73a located on top of the leg shield 27 can be improved, whereby the road surface can be illuminated more brightly.
In the present invention, the front surface of the leg shield 27 below the angular C-shaped bent section 27a may be formed by the lower inclined section 27c, and the vertical portions 73b may be extended from the upper inclined section 27b to the lower inclined section 27c. 
Since the vertical portions 73b are elongated from the upper inclined section 27b above the angular C-shaped bent section 27a to the lower inclined section 27c below the bent section 27a, light beam(s) can be irradiated in different directions, such as from the vertical portions 73b extending upward and downward, whereby the irradiating property of the headlamp 73 is improved.
Further, in the present invention the headlamp 73 may be formed along the edge of the air intake port 71 provided at the front of the leg shield 27.
Since the head lamp 73 is formed along the edge of the air intake port 71 provided at the front of the leg shield 27, the shape or the size of the air intake port 71 is hardly limited when compared to the case in which a round or rectangular headlamp, as in the background art, is disposed at the front of the vehicle. The design of the present invention allows for the area of the air intake port 71 to be increased, and hence cooling capability of the engine 16 is improved.
Also, in the present invention the headlamp 73 may be formed of one or more LEDs, and may be formed into an M-shape, U-shape or H-shape in front view.
Since the headlamp 73 is formed of the LED(s), the power consumption of the headlamp 73 can be reduced. In addition, by employing the M-shaped, U-shaped or H-shaped headlamp 73, it can give a novel impression to the appearance of the two-wheeled vehicle, whereby the commercial property of the two-wheeled vehicle 10 can be improved.
Although there have been described what are the present embodiments of the invention, it will be understood that variations and modifications may be made thereto without departing from the spirit or essence of the invention, and it is intended that all such variations and modifications are encompassed by the scope of the appended claims. For example, in the embodiments described above, the headlamp includes a portion elongated in a lateral direction and portions elongated in a vertical direction from the ends of the lateral portion, but the invention is not limited thereto, e.g., the headlamp may be configured only of the lateral portion or only of the vertical portion(s). Also, the lateral portion in the present embodiment may be formed into a V-shape but, a linear shape, an inverted V-shape, or an arcuate as well.
