It is an object of the present invention to provide a windshield device for a motorcycle that can suppress rattling of the windshield plate even when the wind pressure increases.

[0005]

According to a first aspect of the present invention, a windshield installed in front of a driver is attached to a vehicle body via a stay member and an adjusting mechanism, and the height of the windshield or the windshield is adjusted by the adjusting mechanism. In the motorcycle windshield with an adjustable inclination angle, the stay member is provided with a horizontal side portion extending in a vehicle width direction at a lower edge portion of the windshield plate, and left and right sides extending vertically from both ends of the horizontal side portion. A vertical side portion is integrally formed, and the horizontal side portion and the left and right vertical side portions of the stay member are fixed to the windshield.

According to a second aspect of the present invention, in the first aspect, the adjusting mechanism supports a front portion of the windshield so as to be able to move forward and backward via a front support member, and a rear portion of the windshield at a rear side. The windshield is rotatably supported by a vehicle body via a support member, and the height position and the inclination angle of the windshield can be adjusted with the movement of the front support member. A front support member of the adjustment mechanism is characterized in that left and right rear support members of the adjustment mechanism are connected to left and right vertical sides of the stay member.

According to a third aspect of the present invention, in the first or second aspect, the stay member is disposed on a back surface of the windshield, and a washer member having substantially the same shape as the stay member is disposed on the surface of the windshield. A windshield is sandwiched and fixed between the washer member and the stay member.

According to a fourth aspect of the present invention, in the third aspect, a concave portion is formed at a lower edge of the windshield to form a traveling wind inlet with a vehicle body cover surrounding a headlight of the vehicle body. It is characterized in that the lateral sides of the member and the washer member are bent in a shape along the recess.

[0009]

According to the first aspect of the present invention, the stay member is formed integrally with a lateral side extending in the vehicle width direction and left and right vertical sides extending vertically from both ends of the lateral side. Since both the horizontal and vertical sides of the stay member are fixed to the windshield, the rigidity of the windshield can be increased by the rigidity of the stay member itself, and the rigidity of the windshield itself can be increased. Since there is no need to increase the thickness, it is possible to avoid problems such as distortion of visibility, cost increase, and weight increase due to thickening of the windshield.

According to the second aspect of the present invention, the adjusting mechanism is supported on the vehicle body via the front support member and the rear support member, and the height position of the windshield plate is increased with the movement of the front support member.

In the state where the inclination angle is maximum, h5 'is obtained. Therefore, the traveling wind introduction opening B has a minimum opening area when the inclination angle of the windshield plate 2 is minimum, and increases as the inclination angle increases, and becomes maximum when the inclination angle is maximum.

The drive mechanism 18 includes a motor unit 20
And a feed screw casing 23 is connected to the feed screw casing 23 via a speed reducer 21. The output gear 20a of the motor unit 20 meshes with the input gear 21a of the speed reducer 21, and the output gear 21b of the speed reducer 21
2a are engaged with each other, and the nut portion 19b of the nut member 19 is screwed onto the feed screw 22. The nut portion 19b of the nut member 19 is guided by a guide rod 23b disposed in the feed screw casing 23 in parallel with the feed screw 22. In addition, the arm portion 19a
Protrudes outward through the slit 23a of the feed screw casing 23.

The feed screw casing 23 of the drive mechanism 18 is bolted and fixed to a support bracket 6d formed at the front end of the center stay 6 so as to be inclined obliquely rearward and upward. Accordingly, the drive mechanism 18 is positioned such that the feed screw 22 and thus the feed screw casing 23 are located substantially on the vehicle center line in plan view, and the front end thereof is sandwiched between the left and right headlights 24, 24 in side view. Further, the feed screw casing 23 is disposed so as to be inclined rearward and obliquely upward. The transmission 21 is located at the rear end of the feed screw casing 23, and the motor unit 20 is disposed below the transmission 21 in the vehicle width direction. The motor unit 20 and the transmission 21 are arranged in the bow shape formed by the upper pipe 7 and the meter plate 9 and along the meter plate 9.

Next, the operation and operation and effect of the embodiment 1 will be described. When the windshield operation switch (not shown) is on the low inclination side, the connecting pin 16d of the front support member 16 of the windshield 2 is located at the forward end as shown by the solid line in FIGS. Is tilted forward, whereby the windshield plate 2 is urged by the urging spring 25 to the low inclination state having the gentlest inclination angle.

When the operation switch is pressed to the high inclination side, the feed screw 22 is rotationally driven via the motor unit 20 and the transmission 21 during this time, whereby the nut member 19 is connected to the lower end connecting pin 16 d of the front support member 16. Is moved obliquely rearward and upward, whereby the link member 17 rotates clockwise in FIG. 3, and the windbreak plate 2 changes to the high-inclination state side shown by the two-dot chain line in FIG. 3.

With the rotation, the front support member 16
A forward / backward moving straight line d connecting the low-incline position and the high-incline position of the connection pin 16d and the connection pin 17e, 1 of the link member 17
The angle formed by the member axis e connecting 7d increases from θ1 to θ2. Further, with the rotation, the front end 2c of the windbreak plate 2 rises by h1 and retreats by w1, and the rear end 2d rises by h2 and moves forward by w2.

In the apparatus 1 of the present embodiment, the support stay 4 has a structure in which a center stay 6 fixed to the head pipe 5a is provided with a center portion (lateral side portion) 7a extending in the vehicle width direction and an upper portion following both ends thereof. The upper pipe 7 is fixed to the upper pipe 7 and the supporting columns 8 fixed to the left and right inclined sections 7b of the upper pipe 7 are arranged in the vehicle width direction. Since the configuration of connection with the meter plate 9 is adopted, the upper pipe 7 and the meter plate 9 form an annular body that stands upright in the vertical direction, and the annular body supports the windshield 2. The windshield 2 can withstand this load even when a large load acts on the windshield 2 due to the traveling wind.
The rattling can be prevented.

The height position and the inclination angle of the windshield 2 are adjustable, and the rear part of the windshield 2 is located at the connecting portion between the upper pipe 7 and the meter plate 9 which form an annular body standing upright in the vertical direction. Since the support is provided by the support columns 8, even when the load increases due to an increase in the height position and the inclination angle of the windshield 2, the load can be withheld and the play of the windshield 2 can be prevented.

When the lower end of the front support member 16 fixed to the front portion of the windshield plate 2 is moved from the forward position to the retreat position, the forward / backward moving straight line d of the front support member 16 and the member axis e of the link member 17 are moved. The angle formed by the windshield 20 increases from θ1 to θ2.
The rear end 2d is moved forward by w2 and raised by h2, and
Can be greatly erected as α.

Further, since the urging spring 25 urges the link member 17 and thus the windshield plate 2 in the same direction as the rotational urging direction by the traveling wind, it is possible to avoid the problem that the windshield plate 2 rattles during traveling.

As a method of driving the lower end of the front support member 16 forward and backward, the rotation of the motor 20 is converted into the rotation of the feed screw 22, and the front support member 16 is moved forward and backward by the nut member 19 attached to the feed screw 22. A driving method can be adopted, and the structure of the driving mechanism 18 is simple.

Further, since the inclination angle of the windshield 2 is increased as the front support member 16 is moved to the retracted position, the windshield effect can be further enhanced.
That is, in order to increase the inclination angle to enhance the windshield effect, it is effective that the distance from the driver to the windshield plate 2 does not increase when the inclination angle is increased. For example, windshield 2
The front end portion of the windshield is rotatably supported, and the windshield 2 is rotated around the front end to increase the inclination angle. With the increase in the inclination angle, the windshield is moved forward. Move away from the driver. On the other hand, in the present embodiment, since the inclination angle of the windshield 2 is increased by retreating the front support member 16, the amount of movement of the windshield 2 to the front when the inclination angle is increased. And the windshield effect can be enhanced.

Further, when the inclination angle of the windshield 2 is increased, the front portion of the windshield 2 is retracted, so that it is possible to avoid an increase in the arrangement space including the rotation area of the windshield 2. .

Since the connecting pin (the other end shaft support portion) 17e of the link member 17 is disposed on the anti-windshield side with respect to the forward and backward moving straight line d, the support structure of the link member 17 to the vehicle body is simple and It is easy to secure necessary rigidity. That is, if the connecting pin 17e is arranged closer to the windshield than the forward-backward straight line d, the distance from the vehicle body becomes longer, and the support column 8 needs to be longer, which is disadvantageous in securing rigidity. Such problems can be avoided.

The connecting pin 17e of the link member 17
Is arranged closer to the windshield than the forward-rearward straight line d and the connecting pin (one-end shaft support) 17d is located closer to the windshield than the forward-rearward straight line d in the entire rotation area of the link member 17. Even when the windshield 2 is receiving wind pressure due to the traveling wind while the motorcycle is running, the operation of the windshield 2 can be performed smoothly.

That is, if both linking pins 1 of the link member are
In the case of a structure in which the state in which 7d and 17e are positioned on the forward / backward straight line d occurs, the rate at which the driving force accompanying the retreat of the lower end portion of the front support member 16 is converted to the rotational force of the link member 17 decreases. When the above-mentioned wind pressure is acting, the above-mentioned driving force (rotational force of the link member) cannot overcome the wind pressure, and the operation is not smooth.

Further, since the forward / backward moving straight line d is inclined obliquely rearward and upward, the front support member 16 and, consequently, the windshield 2 are raised with an increase in the angle of inclination of the windshield 2, so that the windshield is more reliably secured. The height of the board can be raised.

The lower edge of the windshield 2 and the cowling 1
2, the traveling wind introduction opening B is formed, and the area of the opening is increased as the inclination angle of the windshield plate 2 is increased. Is introduced between the windshield 2 and the driver, so that even when the vehicle travels at high speed, it is possible to prevent the traveling wind from generating a negative pressure between the windshield 2 and the driver.

Further, since the guide projection 12e for guiding the traveling wind to the traveling wind introducing opening B is formed in the cowling 12, the traveling wind can be more reliably introduced into the traveling wind introducing opening B.

Since the vehicle body-side portion of the front support member 16 is disposed by effectively utilizing the space formed on the back surface of the guide projection 12e, the provision of the adjusting mechanism 3 reduces the space for disposing other vehicle-mounted components. Narrowing can be suppressed.

Further, in the present embodiment, the driving mechanism 18
In the above arrangement, the feed screw 22 is positioned so as to be along the advance / retreat direction of the front support member 16, and the transmission 21 and the motor unit 20 are positioned so as to be located at the retreat position side of the front support member 16. When viewed from the side of the vehicle, most of the drive mechanism 18 is mounted on the front support member 16.
, The space required for the entire windshield device can be reduced, and the entire device can be made compact. By the way, in the conventional device described in the above-mentioned publication, the drive mechanism is disposed so as to extend forward of the shaft 12 at the front end, so that an arrangement space necessary for the entire windshield is increased.

The transmission 21 and the motor unit 2
0 is located in the bow-shaped space formed by the strip-shaped meter plate 9 and the upper pipe 7 arranged so as to extend in the vehicle width direction, and is arranged along the meter plate 9. The transmission 21 and the motor unit 20 can be arranged using the space below the plate 9, and the substantial arrangement space of the drive mechanism 18 can be further reduced.

Further, since the driving mechanism 18 is disposed such that the front end of the feed screw 22 is sandwiched between the left and right headlights 24, 24, the left and right headlights 2 are provided.
When the drive mechanism 18 is provided, the drive mechanism 18 can be arranged by utilizing the space generated between the headlights, and the substantial arrangement space can be further reduced.

The stay member 13 is formed by integrally forming a horizontal side portion 13a extending in the vehicle width direction and left and right vertical side portions 13b extending vertically from both ends of the horizontal side portion 13a.
The side portion 13a of the stay member 13 is attached to the windshield plate 2.
Since both the right and left vertical sides 13b are fixed, the rigidity of the windshield 2 can be increased by the rigidity of the stay member 13 itself, and there is no need to increase the rigidity of the windshield itself.
It is possible to avoid problems such as distortion of visibility, cost increase, and weight increase due to thickening of the windshield.

The side portion 13 of the stay member 13
a, since the front support member 16 and the left and right link members (rear support member) 17 are connected to the left and right vertical side portions 13b, an adjusting mechanism is provided for the high rigidity portion of the windshield plate 2 whose rigidity is increased by the stay member 13. 3, the necessary support rigidity can be ensured even when the wind pressure increases due to high-speed running, and the problem that the windshield plate rattles can be avoided.

Further, the windshield 2 is connected to the stay member 1.
3 and the washer member 14, and the side portions of the stay member 13 and the washer member 14 are bent and formed into a shape along the concave portion 2 a of the lower edge of the windshield plate 2 constituting the traveling wind introduction opening B. The rigidity of the windshield 2 can be further increased.
