Description

[Detailed Description of the Invention] The present invention relates to an improvement of a rear cowl device provided at the rear of a seat of a motorcycle.

On motorcycles, a rear cowl is attached to the rear of the seat for reasons such as rectifying flow and improving appearance. Conventionally, the rear cowl only extends to the rear of the seat, and the fuel tank and the sides below the seat are covered with separate side covers. , and the seat, including the seat bottom plate, was provided separately.

Therefore, a rear cowl and side covers on both sides are required, which increases the number of parts, and also requires mounting parts and installation work for each of the rear cowl and side covers, which is disadvantageous in that the number of parts and work hours also increase. There is.

Moreover, the structure of the seat becomes complicated, such as the need to attach a highly rigid low plate to the bottom of the seat cushion, and the production of the seat becomes troublesome and complicated.

The present inventor devised the present invention in order to solve the above-mentioned problems.The purpose of the present invention is to extend the mud wall of the rear cowl body forward to give shape to the seat bottom plate, and to Parts of the side covers are provided on both sides of the seat bottom plate, and these extend to both sides of the seat bottom plate and the rear lower part of the front fuel tank, and these are molded as a whole, reducing the number of parts and improving the structure and manufacturing of the seat. To provide a rear cowl device for a motorcycle that is simple, facilitates manufacturing including a rear cowl, reduces installation work, and improves the rigidity and strength of the rear cowl.

Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a side view of a motorcycle 1, in which a fork pipe 5 of a front fork 4 is pivotally connected to the front end of a frame 2 via a helad tube 3 by a bridge 6, and a front wheel is attached to the lower part of the front fork 4. 7 is supported and bridge 6
A handle 8 is attached to the top.

A fuel tank 9 is mounted on the front part of the frame 2, and an engine 10 is mounted below this, and a rear fork extends rearward at the lower rear part of the frame 2 to support the rear wheel 11. A carrier cushion unit 12 is interposed between the rear portions of the frame with its upper portion tilted forward.

In the embodiment, a fairing 13 is attached to the upper front portion to function as a windshield and to rectify air flow from the front.

A rear cowl 14 is attached to the rear of the motorcycle 1 for the purpose of rectifying the flow of air and improving the appearance.

The rear cowl 14 is as shown in FIGS. 2 to 4,
It is provided with a vaginal wall 14c that continues downward from the front end of the earthen wall part 14b of the main body 14a having a reverse concave cross section, and a seat bottom plate part 14d that is curved and continuous from the lower end of the vaginal wall 14c and extends forward in a substantially horizontal direction. .

A rearward concave portion 14e is formed in the front end of the seat bottom plate portion 14d, and a recess portion 14e is bent downward from both sides of the upper wall portion 14b of the main body 14a and on both left and right sides of the seat bottom plate portion 14d. The side cover parts 14f, 14f are provided so as to be continuous in the front and rear, and the side cover parts 14f, 14f are connected to the fuel tank 9 described above from both left and right sides of the seat bottom plate part 14d.
The extension pieces 14g and 14g are extended forward so as to cover the left and right sides of the lower part of the rear, and the tops of the extension pieces 14g and 14g are opened 14h as shown in the figure. At the front end of the extension pieces 14g and 14g and at the lower part of the front part of the side cover, there are mounting parts. 14i... are formed.

Further, outwardly protruding portions 14j, 14j facing obliquely rearward and downward are formed in a portion of the side cover portions 14f at the lower portions of both sides of the seat bottom plate portion 14d.

Furthermore, in the embodiment, the vaginal wall 14c at the rear end of the seat bottom plate portion 14d
An opening 14k is formed in the main body 1 as shown in FIG.
The inside of 4a can be used as a storage space of 14 m for tools and the like.

Each part of the cowl 14 described above is integrally molded from synthetic resin or the like.

The rear cowl 14 has a front extension portion 14g.

14g is attached to the rear of the fuel tank 9 so as to face the left and right sides of the lower part of the rear part 9a of the fuel tank 9, and the attachment is done at the attachment part 14i...
・The seat cushion locking portion 15 provided at the rear of the fuel tank on the frame side is connected to the space 14h and the recess 14.
Place the main body 16a of the seat cushion 16, which has a substantially inverted side surface, on the seat bottom plate 14d, and place the back 16b standing up from the rear of the main body 16a against the vaginal wall 14c, and then place the seat cushion 16 on the rear cowl seat bottom plate 14d. Fix it on top.

This is shown in FIG. Side cover part 14f, 14f
The lower left and right parts of the rear part 9a of the fuel tank 9 are connected to the front extension part 14.
g, and the rear of this is covered with side cover parts 14f, 14f to hide the lower left and right sides and rear of the tank, the rectification, frame, and attached equipment. Therefore, even if a part of the side cover is extended forward and backward to reach the fuel tank, interference with the catch cushion unit is prevented.

Therefore, while attaching the side cover to the rear cowl as described above, interference with the rear cushion unit and the like can be eliminated, and the rear cowl can be attached without changing the arrangement of the vehicle body components.

In Fig. 5, 17 is a band for fixing the tool 18 stored in a space of 14 m, and 19 is a hook 2 attached to the rear of the seat cushion.
This is a locking tool that locks through 0.

As is clear from the above (according to the present invention, the seat bottom plate is integrally provided with the rear cowl, and a part of the side cover is also integrally provided, so that these parts, which were conventionally molded as separate parts, can be made into one part. This makes it possible to reduce the number of parts and costs, minimize the number of mounting locations, and improve the mounting workability, which is preferable for mass production.

In addition, since the seat bottom plate is provided, the seat requires only a seat cushion, which simplifies the manufacture of the seat.A part of the side cover extends to the lower part of the rear of the fuel tank, so both sides of the lower part of the rear of the tank are completely covered, improving the appearance. In addition, the cross section is concave to improve strength and rigidity, and by providing a bulge on a part of the side cover, there is no interference with the rear cushion unit, etc., and it is possible to change the vehicle body components. It has many advantages, such as being able to achieve the above without causing any problems.
