Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame cover structure for a scooter type vehicle.

[0002]

2. Description of the Related Art A general scooter type vehicle is provided with a vehicle body frame made of a steel pipe, a steel plate or the like, and the vehicle body frame is entirely covered with a synthetic resin frame cover. The frame cover is of a split type composed of a plurality of parts, each of which is fixed to the vehicle body frame with screws or the like.

By the way, in many scooter type vehicles, a space between the handlebar and the seat is deeply inserted downward, and a step board on which the rider's feet are placed is provided at this portion. And on the front of this step board,
A leg cover that rises upward is attached, and this leg cover covers the front head of the body frame from the rear, and the front cover that covers the front head of the body frame from the front is attached to the leg cover. There is.

The step board, leg cover, and front cover described above are components of the frame cover.

[0005]

However, in the conventional frame cover structure, it is difficult to accurately position the leg cover when the leg cover and the step board, which are large parts, are fixed to the vehicle body frame. At the same time, it was difficult to align the leg cover and the step board, and sometimes a discrepancy (step) occurred, which necessitated re-installation, resulting in extremely poor assembly workability.

The present invention has been made to solve the above problems, and facilitates the positioning of the leg cover and the vehicle body frame, and the positioning of the leg cover and the step board, and the workability of assembling the frame cover. It is an object of the present invention to provide a frame cover structure for a scooter type vehicle that can improve the above.

[0007]

In order to achieve the above object, a frame cover structure for a scooter type vehicle according to the present invention has a low floor type step in which a space between a handlebar and a seat is deeply inserted downward. In a frame cover structure of a scooter type vehicle in which a board is provided and a leg cover rising from the front of the step board covers the front head of the vehicle body frame from the rear, the leg cover is positioned on the vehicle body frame by a positioning means. At the same time, the upper portion of the leg cover is fixed to the vehicle body frame by the upper portion fixing means, and the lower portion of the leg cover is fixed to the step board fixed to the vehicle body frame by using the fitting means and the lower portion fixing means in combination. It is characterized by.

[0008]

With this structure, the leg cover can be easily positioned on the vehicle body frame by the positioning means, and the upper portion of the leg cover can be quickly fixed to the vehicle body frame by the upper portion fixing means. Further, since the leg cover and the step board can be easily aligned with each other by the fitting means, the leg cover and the step board can be quickly fixed by using the lower fixing means, and these can be used for the frame cover. Assembly workability of is greatly improved.

The positioning pedestal 26 is integrally provided in the central portion of a step bracket 28 which is horizontally mounted on the frame pipe 5 to support the step beams 17, 17.

The second positioning means B includes positioning holes 31 and 31 formed at both ends of a support arm 30 fixed to the frame pipe 5, and a lower portion of the leg cover 20 as shown in FIG. And a pair of left and right positioning projections 32, 32 projecting forward toward the front, and the positioning projections 32, 32 are positioned respectively in the positioning holes 31, 31.
The front and rear positions and the left and right positions of the leg cover 20 are determined by fitting the leg cover 20 from the rear side.

The upper portion of the leg cover 20 is fixed to the vehicle body frame 2 by the upper fixing means C. As shown in FIG. 4, the upper fixing means C includes, for example, a fastening bracket 33 fixed to the rear surface of the head pipe 7, a fastening pedestal 34 provided on the upper portion of the leg cover 20, and the fastening bracket 33. And a nut 35 that is fastened to the first positioning means A and the second positioning means B described above.
By fitting the upper fastening table difference 34 of the leg cover 20 positioned by the vehicle body frame 2 into the fastening bracket 33 and fastening the nut 35, the leg cover 2
The upper part of 0 is fixed to the body frame 2.

On the other hand, the lower part of the leg cover 20 is fixed to the front part of the step board 16 by using the fitting means D and the lower fixing means E together (the fitting means D and the lower fixing means E are shown in FIG. In FIGS. 3, 5, and 6, (D),
It shows with (E). ).

As shown in FIGS. 2 and 5, the leg cover 2
A stepped flange 36 is formed on the lower edge of the step 0, and the flange 36 is superposed on the lower surface of the front part of the step board 16 cut in a U shape.

As shown in FIGS. 5 and 6, the fitting means D is, for example, 6 formed in the base portion of the flange 36.
It comprises one fitting hole 37 to 42 and six fitting claws 43 to 48 formed on the front part of the step board 16 so as to be fitted into the fitting holes 37 to 42, respectively. In addition,
The fitting claws 43 and 48 located at both ends are formed into a hook shape that is divided into two parts, and the fitting claw 45 located in the center part.
And 46 are key-shaped facing outward so that they are hard to come out when they are fitted into the fitting holes 37, 42 and 39, 40, respectively.

As shown in FIGS. 2, 3, 5, and 6, the lower fixing means E is, for example, a pair of left and right fixing recesses 50, 5 integrally formed with the flange 36 of the leg cover 20.
0 and the front lower surface of the step board 16 are integrally formed,
A pair of left and right fixed convex portions 51, 51 corresponding to the fixed concave portions 50, 50, a clip-shaped nut 52 mounted on the fixed convex portions 51, 51, and fixed concave portions 50, 50, respectively.
Are fixed to the fixed convex portions 51, 51, respectively.

Then, the step board 1 is inserted into the fitting holes 37 to 42 of the leg cover 20 which is previously fixed to the vehicle body frame 2.
By fitting the fitting claws 43 to 48 of No. 6, the fitting means D is fitted, and together with this, the fixing concave portions 50, 50 of the leg cover 20 are fixed to the fixing convex portions 51, 51 of the step board 16.
51 and the screw 53 is tightened from the front to fix the lower fixing means E.

After that, the step board 16 is attached to the step beam 1 of the vehicle body frame 2 by the four bolts 18.
The step board 16 is fixed by tightening it on top of Nos. 7 and 17.

By the way, as shown in FIGS. 2 and 4, the front cover 21 has, for example, three screws 56 on front stays 54 and 55 fixed to the head pipe 7.
It is fastened to the leg cover 20 by a plurality of engaging means such as tabs (not shown), and is further fixed to the front lower cover 22 by screws 57.

On the other hand, the front lower cover 22 has screws 5
Leg cover 20 with 8, 59 and plural tabs
And is fastened to the step bracket 28 of the vehicle body frame 2 with screws 60. The rack 23 is fastened to the leg cover 20 and the front lower cover 22 by using the screws 58 and 59, so that the number of screws used can be reduced.

In the frame cover structure as described above, the first positioning means A and the second positioning means B are used when fixing the leg cover 20 to the vehicle body frame 2.
Since the leg cover 20 can be easily positioned by the above, the leg cover 20 can be quickly fixed to the vehicle body frame 2 by the upper fixing means C.

Further, the leg cover 20 and the step board 16 can be easily aligned with each other by the fitting means D, so that the leg bar 20 and the step board 16 do not cross each other and a step is not generated. Using the lower fixing means E, the leg cover 20 and the step board 1
6 and 6 can be quickly fixed.

In this way, the leg cover 20 which is a large component and the step board 16 can be easily mounted, so that the workability of assembling the frame cover 15 is greatly improved.

The structures of the first positioning means A and the second positioning means B, the upper fixing means C and the lower fixing means E, and the fitting means D are not necessarily limited to those in this embodiment, and other structures are possible. It can also be a structure of.
