Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a windshield device for motorcycles and other vehicles.

Conventionally, this type of device is known in which a windshield plate is bolted to the front of the vehicle body through a long hole formed in the windshield plate, and the windshield plate is adjusted and moved up and down along the long hole. Although the height of the windshield can be adjusted according to the physique of the occupant, the distance from the occupant to the windshield cannot be adjusted, and the windshield may be too close, giving the occupant a feeling of pressure, or too far away. In addition, if the height of the windshield plate is increased, air resistance increases.

An object of the present invention is to provide a device that eliminates such inconveniences, and in which a windshield plate is provided at the front of the main body so as to be adjustable and movable up and down, the windshield plate can be moved vertically. It is characterized in that it is supported on the vehicle body via a guide mechanism so that the angle of inclination in the longitudinal direction changes.

Embodiments of the present invention will be described below with reference to the drawings.

Referring to FIG. 1, reference numeral 1 denotes a vehicle body equipped with wheels 2 at the front and rear, an engine 3 in the middle of the vehicle body 1, a fuel tank 4 above the engine 3, and a passenger seat 5 behind the tank 4. were arranged to form a motorcycle as a whole. A windshield plate 6 is attached to the front part of the vehicle body 1 so as to be adjustable and movable up and down according to the physique of the occupant.

Although the above is not particularly different from the conventional one, according to the present invention, the windshield plate 6 is supported on the vehicle body 1 via the guide mechanism 7 so that the inclination angle in the front and rear direction changes as the windshield plate 6 moves up and down. The guide mechanism 7 will be described in detail with reference to the one shown in the figure. As shown in FIGS. The windshield plate consists of a pair of guide grooves 8a, 8a formed to have a large rearward inclination angle, and a pair of guide rollers 9, 9 that are slidable along each guide groove 8a. A pair of guide rollers 9, 9 are pivotally attached to both sides of the windshield plate 6, and these are fitted into the respective guide grooves 8a, and the windshield plate 6 is supported by the vehicle body 1 via the stay 8. When the windshield plate 6 is moved upward, the angle of inclination of the windshield plate 6 toward the rear increases.

The stay 8 may be attached to the vehicle body 1 using a separately prepared bracket, but in the illustrated example, the stay 8 is attached to the front fairing 10 of the vehicle body 1.
The mounting stay 11 is used to attach to the mounting stay 11 by welding or the like.

In the drawings, reference numeral 13 indicates a seal rubber attached to the windshield plate 6 at the end of the fairing 10.

Furthermore, in the illustrated example, in order to adjust and move the windshield plate 6 electrically, there is provided a drive source 14a such as a motor, and a bushing rod 14c that is slidable in the vertical direction and is interlocked with the drive source 14a via a gear in a gearbox 14b. A power unit 14 consisting of
is attached to the lower end of the windshield plate 6 via a ball joint 14d, so that the windshield plate 6 is given vertical movement by the drive source 14a.
In addition, since the occupant leans forward when driving at high speed, the height of the windshield plate 6 should be adjusted accordingly, but in this case, simply lowering the height would not be aerodynamically preferable.
Since it is desired to increase the rearward inclination angle of the windshield plate 6, the guide grooves 8a, 8a are
The lower part of the windshield plate 6 is formed to have a large rearward inclination angle, so that when the windshield plate 6 is moved downward, the rearward inclination angle of the windshield plate 6 increases as shown in FIG. 4c.

Next, its operation will be explained.

When the windshield plate 6 is moved upward from the position of the small-sized occupant shown in FIG. 4b to the position of the large-sized occupant shown in FIG. Since the position is relatively behind the seat 5, if the height of the windshield plate 6 were simply changed as in the conventional example, the position would be as shown by the dotted line in the figure, and the distance from the passenger to the windshield plate 6 would be large. It becomes easy to cause wind insertion.

In contrast, in the case of the present invention, as the windshield plate 6 moves upward, it is guided by each guide groove 8a of the guide mechanism 7, and the rearward inclination of the windshield plate 6 increases. This maintains an optimal distance to the vehicle, and also suppresses increases in aerodynamic drag.

As described above, according to the present invention, the windshield plate is supported on the vehicle body via the guide mechanism so that the angle of inclination in the front and back direction changes as the windshield moves up and down, and is optimally suited to the physique and riding position of the occupant. Not only can the windshield plate be easily set, but it also has effects such as being advantageous in terms of aerodynamics.
