Description

The present invention relates to a storage structure for an auxiliary step mounted on a frame of a motorcycle.

[Prior art]

FIG. 7 is a fragmentary perspective view showing the frame 1 of the motorcycle, and particularly shows the main part of the seat rail 3 which supports the passenger seat 2.

Conventionally, a step for passengers, that is, an auxiliary step 4, is a frame that is located above a rear wheel of a motorcycle, a bracket 6 fixed to a seat rail 3 and a sub rail 5 that reinforces the seat rail 3, and the bracket. It is constituted by a so-called retractable foot-riding portion 7, which is rotatably supported by the tip 6a of the rod 6.

In this assisting step 4, the foot riding portion 7 is folded to accommodate the frame 1 side when traveling alone, and is folded to the position indicated by the alternate long and short dash line so that the passenger can use the vehicle during tandem traveling (two-seater traveling). To use.

Incidentally, in the conventional auxiliary step 4, there is also one in which the footrest 7 is supported by a muffler bracket or the like (not shown) so as to be bendable in addition to the above-described configuration. In FIG. 7, reference numeral 8 is a frame cover that extends below the lower edge of the seat rail 3 that covers the lower left and right sides of the passenger seat 2. The frame cover 8 covers the side of the seat rail 3. It is a thing.

By the way, according to the conventional auxiliary step 4 described above, the footrest portion 7 may be used or not used,
Since it is exposed to the side of the vehicle, it is a factor that increases air resistance when traveling alone on a highway or the like. Further, in the conventional example shown in FIG. 7, since the bracket 6 and the foot riding portion 7 are fixed to the side of the seat rail 3, it is difficult to check and maintain the rear wheels (not shown) and the like. There were also points.

[Object of the Invention]

In view of the above-mentioned problems, an object of the present invention is to provide an auxiliary step storage structure for a motorcycle that reduces air resistance and improves workability of maintenance and inspection.

[Structure of Invention]

According to the present invention, the frame is located above the rear wheel of the motorcycle, the passenger seat is disposed on the frame, and the frame is provided below the lower edge of the frame that covers the lower left and right sides of the passenger seat. In a motorcycle including a frame cover and an auxiliary step in which one end of an arm portion is attached to the frame and a foot riding portion is provided at the other end, the frame side attachment portion of the arm portion of the auxiliary step is inside the frame cover. Further, it is provided at a position above the lower edge of the frame cover, and the foot riding portion projects outside the frame cover in a direction substantially perpendicular to the outer surface of the frame cover. The frame is rotatably pivoted to the storage position above the lower edge of the cover, and the arm part is rotated to one side when the foot riding part is used. Foot multiplication portion protruding outside of the frame cover, also by rotating the arm to the other when not in use the foot multiplication portion, so as to house the foot multiplication section to the frame cover.

〔Example〕

Hereinafter, one embodiment of the auxiliary step according to the present invention will be described in detail.

FIG. 1 is a fragmentary perspective view of a main part of a frame 1 showing a storage structure for an auxiliary step according to the present invention, and the same parts as those in FIG.

The auxiliary step 10 according to the present invention is composed of an arm portion 12 and a foot riding portion 11 which is vertically arranged at a tip 12a of the arm portion 12.

On the other hand, one end of the arm portion 12 constituting the auxiliary step 10 is attached to the frame 1 in a manner described later.

As shown in FIG. 2, the auxiliary step 10 has a shaft 12c at one end of the arm portion 12, that is, at the frame side mounting portion 12b. In addition, the shaft 12c is inclined approximately 20 ° obliquely upward with respect to the foot riding portion 11 and approximately 45 ° forward.

On the other hand, the bearing portion 5a for pivotally mounting the above-mentioned shaft 12c on the frame 1
The hole 5b is attached such that its axis is inclined obliquely downward by approximately 20 ° and rearward by approximately 45 ° with respect to the sub-frame 5 (vehicle body) constituting the frame 1.

As described above, the auxiliary step 10 axially attached to the sub-frame 5 constituting the frame 1 has its shaft 12c inserted into the bearing hole 5b as shown in FIG. 3 which is a sectional view taken along the line AA of FIG. And, the pin 5c is planted at the tip.

The pin 5c prevents the shaft 12c from slipping out of the bearing hole 5b, and also serves as a stopper for positioning the foot riding portion 11 at the use position.

Next, the operation of the above-described auxiliary step 10 will be described, and the configuration will be described in more detail.

The position of the auxiliary step 10 shown by the solid line in FIGS. 1 to 4 is the use position of the foot riding portion 11, and the foot riding portion 11 is outside the frame cover 8 and is substantially perpendicular to the outer surface of the frame cover 8. Protruding in the direction.

is there.

On the other hand, when the foot riding portion 11 is not used, the force may be applied in the direction of the arrow 8 by directing the foot riding portion 11 or the arm portion 12 toward the rear of the vehicle body.

Then, the arm portion 12 and the footrest portion 11 move to the lower portion of the subframe 5 covered by the frame cover 8 while changing the postures with respect to the frame cover 8, and the same portions as those in FIG. As shown by the solid lines in FIG. 5 and the top view of FIG.
Along the path, and stop at the position where the tip of the foot riding portion 11 is directed downward.

Therefore, when the foot riding portion 11 is not used, the foot riding portion 11 and the arm portion 12 supporting the foot riding portion 11 are stored in the frame cover 8.

When it is desired to hold the auxiliary step 10 in its retracted position reliably, a locking mechanism may be interposed between the shaft 12c and the bearing portion 5a.

In the above embodiment, the shaft 12c and the hole 5b of the bearing portion 5a.
Are formed so as to be inclined with respect to the vehicle body, and
Is fixed to the tip 12a of the arm portion 12, of course, the present invention is not limited to the above embodiment, the shaft 12c out of the hole 5b of the shaft 12c and the bearing portion 5a parallel to the foot riding portion 11. Place and
The holes 5b of the bearing portion 5a are arranged in a direction perpendicular to the sublay 5 (parallel to the ground contact surface of the vehicle body and perpendicular to the traveling direction of the vehicle), and the footrest portion 11 can be attached to the arm portion 12 as in the conventional case. It is arranged so that it can be folded down, and when the footrest 11 is not in use, the footrest 11 is bent toward the arm 12 side, and then the arm 12 is rotated along the side of the frame 1 so that the inside of the frame cover 8 is closed. In other words, the frame-side mounting portion 12b of the arm portion 12 of the auxiliary step 10 may protrude in a direction substantially perpendicular to the outer surface of the frame cover 8 when in use, and may also be stored in the frame. The frame 1 may be pivotally mounted so that it is stored at a position above the lower edge of the cover 8.

〔The invention's effect〕

In the auxiliary step storage structure according to the present invention, the arm portion is rotated to one side when used to project the foot step portion of the auxiliary step to the outside of the frame cover, and the arm portion is rotated to the other side when not used to rotate the auxiliary step. Since the foot riding portion of the motorcycle is housed in the frame cover, the air resistance of the motorcycle can be reduced while traveling alone, and the maintenance and inspection work of the rear wheels and the like can be facilitated.
