Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a windscreen for a motorcycle, and more particularly to the structure of a windscreen support including the windscreen.

Conventional technology and its problems Conventionally, a motorcycle is provided with a windscreen made of a transparent resin material or the like on the front surface of the upper part of the vehicle body, thereby ensuring the visibility of the occupant and preventing the wind from hitting the occupant. There is. This windscreen is usually connected to a fairing that covers the upper part of the vehicle from its front side to both sides, and stands upright from the upper edge of the fairing. Then, the pressure receiving area with respect to the wind pressure becomes large, so that the windscreen is easily warped or fluttered.

Means and Actions for Solving Problems In order to solve the above problems, according to the present invention, the lower edge portion is located outside the left and right ends of a windscreen that can be received from the inside by a vehicle body member via step portions. An overhanging portion that extends to a position above the lower edge portion, and a receiving plate that protrudes upward at both left and right end portions of the vehicle body member and that faces the overhanging portion. The projecting portion is received by the receiving plate via the cushioning member.

Since the windscreen according to the present invention has the bulged portions which are bulged outward at the lower portions of both left and right sides through the stepped portions, respectively, the cross-section coefficient is large, and the both ends, which are more prone to flutter, are projected upward from the vehicle body member. Since it is received by the receiving plate, it is possible to effectively prevent warping and fluttering from both sides of the shape and the mounting structure.

Embodiment FIG. 1 is a side view of a motorcycle to which the present invention is applied, in which 1 is a front wheel, 2 is a rear wheel, and 3 is an exhaust pipe. As shown in the drawing, the motorcycle is covered with a cover member over the front surface of the vehicle body. That is, the front part of the vehicle body is covered with the fairing 4 from the front to both sides, the both rear parts thereof are covered with the side shelters 5, and the both sides of the rear wheel 2 behind that are covered with the saddle bags 6. . A seat 7 for two persons is provided near the rear of the upper part of the vehicle body, and a storage compartment 8 is provided at the rear of the seat 7. A handle 9 is arranged in front of the seat 7, and a wind screen 10 made of a transparent resin plate is connected to the upper edge of the fairing 4 and stands up in front of the handle 9.

The fairing 4 is a fairing stay 11 on the body frame.
Is fixed through. A meter panel 12 is provided inside the fairing 4 as shown in FIG. 2, and a speedometer 14 is provided in a meter box 13 on the panel.
Various instruments are installed. As shown in FIG. 9, the meter cable 15 connected to the speedometer 14 is passed through the cylindrical portion 16 welded to the fairing stay 11, and when the steering wheel 9 is operated, the steering wheel and the steering responsive thereto are operated. It is held so that it does not interfere with the system. The cylindrical piece 16 also serves to reinforce the fairing stay 11.

The handle 9 has a handle pipe 17 as shown in FIG.
Both left and right arm parts are covered with a resin handle cover 18, and a wire harness 19 is passed between the handle cover 18 and the handle pipe 17. A control box 20 is attached to an end portion of the right handle cover 18, and a throttle control cable 22 interlocking with a throttle grip 21 extends from the control box 20. As shown in FIG. 11, the control cable 22 is held by a stopper fitting 23 fixed to the handle pipe 17 and protruding from the handle cover 18 to the outside so that the control cable 22 does not loosely move from a position along the handle cover 18. There is. This stopper 23 is also provided inside the handle cover 18 for the wire harness 19
Holding

As is well known, the control cable 22 passes a core wire in an outer tube whose tip is fixed to the vehicle body, and this core wire interlocks with the throttle grip 21 to move in and out from the tip of the outer tube, so that the throttle connected to the core wire is connected. The valve is designed to operate, but an adjusting device 24 for adjusting the protruding length of the core wire from the tip of the outer tube by expanding and contracting the length of the outer tube is provided in the portion of the control cable 22 on the control box 20 side. Has been. FIG. 12 shows the detailed structure of the adjusting device 24. The outer tube is divided in the adjusting device 24 into a front portion 25a and a rear portion 25b, and male threads 26a and 26b are respectively threaded on the ends of both portions.
However, the male screw 26a and the male screw 26b are screws (right-hand screw and left-hand screw) in opposite directions. A common adjusting nut 27 is screwed on the male screws 26a and 26b.
Therefore, when the adjusting nut 27 is turned, the front portion 25a and the rear portion 25b of the outer tube are separated or close to each other, whereby the entire length of the outer tube expands and contracts, and the protruding length of the core wire 28 from the tip of the outer tube is adjusted. . Reference numerals 29 and 29 are lock nuts for fixing the adjusting nut 27 at the adjusting position.

As can be seen from FIG. 1, a side cover 30 is provided at the lower rear portion of the side shelter 5. This part is shown in more detail in FIG. 13, but as can be seen from the figure, an electric component such as a fuse box 31 is housed inside the side cover 30, and the fuse can be removed by removing the side cover 30. It is possible to perform maintenance work and the like by approaching the box 31. The side cover 30 is a side cover.
The three protrusions 32 provided on the 30 side are attached to the 3
It is mounted by inserting it into each of the grommet holes 33 and by inserting the protrusion 34 provided on the vehicle body side into the grommet hole 35 provided on the side cover 30 side. Stud 34 is the 14th
As shown in the drawing, the head of a bolt 36 for fixing the side shelter 5 to the vehicle body frame is integrally formed with the head 36, and one bolt 36 is used to attach the side shelter 5 and the side cover 30. It is used for two purposes.

Now, referring to FIG. 2 to FIG.
10 will be described. As shown in FIG. 6, the windscreen 10 has a long hole 37 provided at a lower edge portion thereof fitted to a protrusion 38 projecting from an upper edge portion piece 4a of the fairing 4 to form an upper edge portion thereof. It is vertically slidably attached to the piece 4a, and is fixed by being pressed from the front by a pressing piece (garnish) 39 (FIG. 7) also serving as a decoration. The eighth
As shown in the figure, the upper edge piece 4a and the windscreen
Cushion rubbers 40 and 41 are inserted between the pressing piece 39 and the windscreen 10, respectively, and a seal rubber 42 is attached to the edge of the pressing piece 39 that engages with the windscreen 10. Has been done.

As shown in FIGS. 7 and 8, the presser piece 39 is loosely attached to the bolt portion piece 43 planted in the upper edge portion piece 4a at the lower front surface thereof, and the side portion rear end portion is connected to the connecting piece piece 44. It is connected to the lever 45 via. The lever 45 is a support plate 46 integrated with the fairing 4.
When the lever 45 is in the position shown by the solid line in FIGS. 7 and 8, the holding piece 39 pushes the windscreen 10 toward the upper edge piece 4a as shown in the drawing. When the lever 45 is rotated as shown by the arrow a, the pressing piece 39 swings around the bolt piece 43 as a fulcrum as shown by the chain double-dashed line and separates from the windscreen 10. Therefore, after such a state, the height can be adjusted by sliding the wind screen 10 up and down.

FIG. 7A is an exploded view of the parts of FIG. 7 in more detail. 49 and 50 are louvers, 51 is a headlight, 52 is a winker lamp, 53 is a rearview mirror, and these are fairings 4. It is assembled in one.

By the way, the lower portions of the left and right end portions of the windscreen 10 are bulged portions 10a that bulge outwards through the stepped portion 47, and behind this bulged portion 10a, the cushion rubber 40 has a thick portion 40a. (See Figure 5). This thick portion 40a is also a bulge, as can be seen in FIG.
It projects further upward from the upper end of the upper edge piece 4a along the inner surface of 10a. This projecting portion is, as described above, a receiving plate 48 projecting at both ends of the meter panel 12 disposed inside the upper edge piece 4a so as to face the projecting portion 10a.
Received from behind by.

In this way, the windscreen 10 in this embodiment is
The lower edge is not only clamped and fixed between the upper edge piece 4a and the pressing piece 39, but also the protruding piece 10a at both ends receives the pressing piece 39 and the receiving piece 39 to a position higher than other parts. It is sandwiched between the plate 48 and is firmly fixed. However, since both ends of the lever are places where fluttering is most likely to occur due to wind pressure, fluttering of the windscreen 10 can be effectively suppressed by this. Also, windscreen 10
Since the rigidity is increased by the stepped portion 47, fluttering is prevented by this and warp of the windscreen 10 due to wind pressure is prevented. Thus, the windscreen 10 is light in weight because it does not have to be locally thickened in order to strengthen its attachment or increase its rigidity. Moreover, the step portion 47 is the wind screen 10
Since it is provided at the lower end of both ends of the passenger compartment, it hardly affects the visibility of passengers.

EFFECTS OF THE INVENTION As described above, in the present invention, the lower edge portion is protruded outward through the step portions at the lower left and right ends of the windscreen that can be received from the inside by the vehicle body member, and more than the lower edge portion. An overhanging portion extending to an upper position is provided, and a receiving plate projecting upward and facing each of the overhanging portions is provided at both left and right end portions of the vehicle body member, and the overhanging portion is supported by the cushion member. I decided to receive it with a board,
The shape and mounting of the windscreen can be made strong with almost no influence on the occupant's field of view and without increasing the weight, and thus the warpage and fluttering due to the wind pressure of the windscreen can be effectively prevented.
