In a windshield apparatus for a motorcycle in the related art, an air vent hole is formed on the portion of a front handle cover where the front surface is inclined upward.
Therefore, since the air vent hole is highly visible, the appearance of the front surface of the vehicle is impaired, and it is necessary to consider to prevent rainwater incoming through the air vent hole during travel in the rain from flushing upward inside a windscreen.
In view of such circumstances, an object of the present invention is to provide a windshield apparatus for a motorcycle in which the good appearance on the front surface of the vehicle is maintained by preventing the air vent hole from being highly visible, and rainwater is prevented from coming into the air vent hole.
SUMMARY OF THE INVENTION
In order to achieve the object described above, in a windshield apparatus for a motorcycle including: a front handle cover attached to a rod-shaped steering handle so as to cover the front surface thereof; and an air vent hole opening toward the front is formed on the front handle cover to allow wind blowing onto the motorcycle during travel to be supplied inside of a windscreen projecting upward from the front handle cover, a first aspect of the invention is characterized in that the front handle cover includes an upper half that is inclined so that the front surface faces upward and a lower half that is inclined so that the front surface faces downward connected with respect to each other so that a lateral ridgeline is formed therebetween, and the air vent hole is formed on the lower half.
According to the first aspect, since the air vent hole on the front handle cover is provided on the lower half, which faces downward, below the ridgeline, the lines of sight of general adults from the front are obstructed by the ridgeline, and thus the air vent hole can hardly be viewed. Therefore, the appearance of the motorcycle is prevented from being affected by the air vent hole. In addition, since the front surface of the front handle cover having the air vent hole faces downward, entering of rainwater into the air vent hole during travel in the rain may be prevented.
In addition to the first aspect, a second aspect of the invention is that an upper handle cover for covering the upper surface of the steering handle with the front edge abutted against, or placed in the vicinity of, the inner surface of the windscreen is attached to the steering handle, a number of air injection holes opening along the inner surface of the windscreen are formed on the front portion of the upper handle cover, and an air guide plate for guiding wind blowing onto the motorcycle during travel and taken through the air vent hole into the air injection holes is disposed between the front handle cover and the upper handle cover.
According to the second aspect, wind entering into the air vent hole of the front handle cover during travel is guided to the air injection holes on the upper handle cover by the air guide plate, and injected from the number of air injection holes. Therefore, generation of negative pressure inside the windscreen is prevented, and thus windshield effect may be improved. In addition, a large gap between the windscreen and the upper handle cover may be eliminated, and thus a good appearance is achieved.
In addition to the second aspect, a third aspect of the invention is that a meter unit is mounted to the upper handle cover, and a meter visor standing from between the meter unit and a group of air injection holes for preventing dizzy light beam from incoming onto the display surface of the meter unit is integrally formed with the upper handle cover.
According to the third aspect, the meter visor standing from behind the group of air injection holes faces the inner surface of the windscreen within a relatively short distance, and serves to define a passage for allowing air injected from the air injection holes to rise with respect to the windscreen, so that dispersion of injected air is prevented to effectively restrain generation of negative pressure inside the windscreen.

Reference numeral 35 in the figure is a back mirror mounted to the steering handle 4.
The operation of this embodiment will be described below.
When wind blowing onto the motorcycle S during travel enters into the left and the right air vent holes 30 on the front handle cover 15, it is guided upward by the air guide plate 16, and is injected from a number of air injection holes 31, 31... formed on the upper handle cover 13. Since the air injection holes 31, 31... are opened upward along the inner surface of the windscreen 12, air injected from the air injection holes 31, 31...
rises along the inner surface of the windscreen 12, whereby generation of negative pressure inside the windscreen 12 can be restrained. Consequently, air current of wind rising along the front surface of the windscreen 12 is prevented from turning into the inside of the windscreen 12, so that windshield effect of the windscreen 12 may be improved.
The meter visor 34 standing upright from behind the group of air injection holes 31, 31... faces the inner surface of the windscreen 12 within a relatively short distance, and thus serves to define a passage for allowing air injected from the air injection holes 31, 31... to rise with respect to the windscreen, so that dispersion of injected air is prevented to effectively restrain generation of negative pressure inside the windscreen 12.
Since the air vent holes 30, 30 of the front handle cover 15 are formed on the lower half 15b, which faces downward, of the front handle cover 15 below the ridgeline 15c, when general adults viewed the motorcycle S from the front, the lines of sight are obstructed by the ridgeline 15c, and thus the air vent holes 30, 30 can hardly be viewed. Therefore, the appearance of the motorcycle S is prevented from being affected by the air vent holes 30, 30. In addition, since the front surface of the front handle cover 15, on which the air vent holes 30, 30 are opened, faces downward, entering of rainwater into the air vent hole 30, 30 may be prevented.
On the other hand, on the inside of the windscreen 12, provision of a number of air injection holes 31, 31... at the front end portion of the upper handle cover 13 enables to eliminate generation of a large gap between the windscreen 12 and the upper handle cover 13 while securing an airflow for controlling negative pressure, so that a good appearance is achieved.
The present invention is not limited to the embodiment described above, and may be modified without departing from the scope of the invention.
As described thus far, in a windshield apparatus for a motorcycle including: the front handle cover attached to the rod-shaped steering handle so as to cover the front surface thereof; and the air vent hole opening toward the front is formed on the front handle cover to allow wind blowing onto the motorcycle during travel to be supplied inside of the windscreen projecting upward from the front handle cover, a first embodiment of the invention is characterized in that the front handle cover includes the upper half that is inclined so that the front surface faces upward and the lower half that is inclined so that the front surface faces downward connected with respect to each other so that the lateral ridgeline is formed therebetween, and the air vent hole is formed on the lower half. Therefore, since the air vent hole on the front handle cover is provided on the lower half, which faces downward, below the ridgeline, the lines of sight of general adults from the front are obstructed by the ridgeline, and thus the air vent hole can hardly be viewed. Therefore, the appearance of the motorcycle is prevented from being affected by the air vent hole. In addition, since the front surface of the front handle cover having the air vent hole faces downward, entering of rainwater into the air vent hole during travel in the rain may be prevented.
In addition to the first embodiment, a second embodiment of the invention is that the upper handle cover for covering the upper surface of the steering handle with the front edge abutted against, or placed in the vicinity of, the inner surface of the windscreen is attached to the steering handle, the number of air injection holes opening along the inner surface of the windscreen are formed on the front portion of the upper handle cover, and the air guide plate for guiding wind blowing onto the motorcycle during travel and taken through the air vent hole into the air injection holes is disposed between the front handle cover and the upper handle cover. Therefore, wind blowing onto the motorcycle during travel and taken through the air vent hole is guided into the air injection holes on the upper handle cover by the air guide plate and injected from a number of air injection holes, whereby generation of negative pressure inside the windscreen is prevented, and windshield effect may be improved. In addition, the large gap between the windscreen and the upper handle cover may be eliminated, and thus a good appearance is achieved.
In addition to the second embodiment, a third embodiment of the invention is that the meter unit is mounted to the upper handle cover, and the meter visor standing from between the meter unit and the group of air injection holes for preventing dizzy light beam from incoming onto the display surface of the meter unit is integrally formed with the upper handle cover.
Therefore, the meter visor standing from behind the group of air injection holes faces the inner surface of the windscreen within a relatively short distance, and serves to define the passage for allowing air injected from the air injection holes to rise with respect to the windscreen, so that dispersion of injected air is prevented to effectively restrain generation of negative pressure inside the windscreen.
Although various preferred embodiments of the present invention have been described herein in detail, it will be appreciated by those skilled in the art, that variations may be made thereto without departing from the spirit of the invention or the scope of the appended claims.
The operation of this embodiment will be described below.
When wind blowing onto the motorcycle S during travel enters into the left and the right air vent holes 30 on the front handle cover 15, it is guided upward by the air guide plate 16, and is injected from a number of air injection holes 31, 31... formed on the upper handle cover 13. Since the air injection holes 31, 31... are opened upward along the inner surface of the windscreen 12, air injected from the air injection holes 31, 31...
rises along the inner surface of the windscreen 12, whereby generation of negative pressure inside the windscreen 12 can be restrained. Consequently, air current of wind rising along the front surface of the windscreen 12 is prevented from turning into the inside of the windscreen 12, so that windshield effect of the windscreen 12 may be improved.
The meter visor 34 standing upright from behind the group of air injection holes 31, 31... faces the inner surface of the windscreen 12 within a relatively short distance, and thus serves to define a passage for allowing air injected from the air injection holes 31, 31... to rise with respect to the windscreen, so that dispersion of injected air is prevented to effectively restrain generation of negative pressure inside the windscreen 12.
Since the air vent holes 30, 30 of the front handle cover 15 are formed on the lower half 15b, which faces downward, of the front handle cover 15 below the ridgeline 15c, when general adults viewed the motorcycle S from the front, the lines of sight are obstructed by the ridgeline 15c, and thus the air vent holes 30, 30 can hardly be viewed. Therefore, the appearance of the motorcycle S is prevented from being affected by the air vent holes 30, 30. In addition, since the front surface of the front handle cover 15, on which the air vent holes 30, 30 are opened, faces downward, entering of rainwater into the air vent hole 30, 30 may be prevented.
On the other hand, on the inside of the windscreen 12, provision of a number of air injection holes 31, 31... at the front end portion of the upper handle cover 13 enables to eliminate generation of a large gap between the windscreen 12 and the upper handle cover 13 while securing an airflow for controlling negative pressure, so that a good appearance is achieved.
The present invention is not limited to the embodiment described above, and may be modified without departing from the scope of the invention.
As described thus far, in a windshield apparatus for a motorcycle including: the front handle cover attached to the rod-shaped steering handle so as to cover the front surface thereof; and the air vent hole opening toward the front is formed on the front handle cover to allow wind blowing onto the motorcycle during travel to be supplied inside of the windscreen projecting upward from the front handle cover, a first embodiment of the invention is characterized in that the front handle cover includes the upper half that is inclined so that the front surface faces upward and the lower half that is inclined so that the front surface faces downward connected with respect to each other so that the lateral ridgeline is formed therebetween, and the air vent hole is formed on the lower half. Therefore, since the air vent hole on the front handle cover is provided on the lower half, which faces downward, below the ridgeline, the lines of sight of general adults from the front are obstructed by the ridgeline, and thus the air vent hole can hardly be viewed. Therefore, the appearance of the motorcycle is prevented from being affected by the air vent hole. In addition, since the front surface of the front handle cover having the air vent hole faces downward, entering of rainwater into the air vent hole during travel in the rain may be prevented.
In addition to the first embodiment, a second embodiment of the invention is that the upper handle cover for covering the upper surface of the steering handle with the front edge abutted against, or placed in the vicinity of, the inner surface of the windscreen is attached to the steering handle, the number of air injection holes opening along the inner surface of the windscreen are formed on the front portion of the upper handle cover, and the air guide plate for guiding wind blowing onto the motorcycle during travel and taken through the air vent hole into the air injection holes is disposed between the front handle cover and the upper handle cover. Therefore, wind blowing onto the motorcycle during travel and taken through the air vent hole is guided into the air injection holes on the upper handle cover by the air guide plate and injected from a number of air injection holes, whereby generation of negative pressure inside the windscreen is prevented, and windshield effect may be improved. In addition, the large gap between the windscreen and the upper handle cover may be eliminated, and thus a good appearance is achieved.
In addition to the second embodiment, a third embodiment of the invention is that the meter unit is mounted to the upper handle cover, and the meter visor standing from between the meter unit and the group of air injection holes for preventing dizzy light beam from incoming onto the display surface of the meter unit is integrally formed with the upper handle cover.
Therefore, the meter visor standing from behind the group of air injection holes faces the inner surface of the windscreen within a relatively short distance, and serves to define the passage for allowing air injected from the air injection holes to rise with respect to the windscreen, so that dispersion of injected air is prevented to effectively restrain generation of negative pressure inside the windscreen.
Although various preferred embodiments of the present invention have been described herein in detail, it will be appreciated by those skilled in the art, that variations may be made thereto without departing from the spirit of the invention or the scope of the appended claims.
