Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a frame grip that is attached to the rear body frame of a motorcycle and is used as a grip when lifting the rear body of a motorcycle, for example, when standing up. It is something.

(Prior Art) This type of grip is generally called a so-called side grip, which is attached to the rear body frame so as to protrude laterally.

Therefore, when installing a cowling, which is a recent trend, especially a rear cowling, to cover the rear body frame, the side grips get in the way, so it is necessary to provide an opening in the rear cowling for the grips to protrude, or to install a lower part in the rear body frame. The side grips are attached via brackets or the like that extend toward the cowling, and are made to protrude laterally from below the cowling.

Furthermore, when the side grips are attached, a load is applied to the attachment portion, so it is necessary to improve the rigidity of the frame by increasing the strength of the reinforcing members and the frame itself. One way to improve this rigidity is to
A structure in which the rear frame is reinforced by the latter bracket (Japanese Patent Application Laid-open No. 59-50884)
is proposed.

(Problem to be solved by the invention) By the way, in the former case, the shape of the rear cowling was restricted, and moreover, it was not very aesthetically pleasing from a design standpoint.

Furthermore, in the latter case, the number of parts increases, making the structure more complicated, and since the side grips protrude laterally, a moment acts on the frame structure when lifting the vehicle body, which is disadvantageous in terms of strength.

This idea was created in view of the above points, and when the rear cowling is installed, it hides inside the cowling and looks good, and is especially suitable for this type of motorcycle.Moreover, the grip itself can be used as a reinforcing member of the frame. The object of the present invention is to provide a frame grip for a motorcycle whose rigidity can be improved.

(Means for solving the problem) The frame grip of this invention includes a pair of upper frames that are parallel to each other and spaced apart by a certain distance,
A motorcycle comprising a rear body frame comprising a pair of sub-frames that are welded to the rear lower surface of the upper frame and tilt downward forward, the lower surface of the rear end of at least one of the upper frames, and the upper frame. Both front and rear ends of a substantially arcuate frame grip are integrally welded to the lower surface of the subframe in front of the joint with the subframe so as to protrude downward, and the frame grip is covered with a rear cowling. The gist of this invention is a frame grip for a motorcycle, characterized in that the lower surface of the frame grip can be supported by inserting a hand from below.

(Function) According to the frame grip of this invention, in addition to functioning as a support when lifting the rear vehicle body,
The grip itself is integrated with the upper frame and the subframe, and has the function of increasing the supporting force against loads acting on both frames, particularly in the vertical direction, and reinforcing the joint between the two frames.

(Example) Hereinafter, an example of this invention will be described based on the drawings. Figure 1 is a side view of a motorcycle equipped with the frame grip of this invention, and Figure 2 is a side view of a motorcycle equipped with the frame grip of this invention.
In these figures, 1 is a motorcycle, and the front end head pipe 2 of this motorcycle 1 is a cross-sectional view.
A main frame 3 having a substantially U-shape when viewed from above and an under frame 4 having a double cradle shape extend rearward, and both frames are joined at the rear end to form a front body frame A. Further, a pair of parallel upper frames 5 extend rearward from the rear of the main frame 3, and a pair of subframes 6 bent in a dogleg shape extend rearward and upward from the rear end of the main frame 3. , the rear end of each subframe 6 is welded to the rear lower surface of the upper frame 5. Both front and rear ends of a substantially arcuate frame grip 7 are integrally welded to the lower surface of the rear end of the upper frame 5 on the left side and the lower surface of the sub-frame 6 in front of the joint with the upper frame 5, and are attached downward. make it stand out. In this way, the rear body frame B is constructed.

8 is an engine mounted in the front body frame A, 9 is a fuel tank mounted from the front end of the main frame A to the front part of the upper frame 5, and 10 is the upper frame 5 behind the fuel tank 9. It is a tandem type seat mounted on top.

11 is an upper cowling attached to the front body frame A, and 12 is an under cowling. Reference numeral 13 denotes a rear cowling, which is attached to the frame B so as to cover the rear body frame B under the seat 10.
will be installed on the Note that the lower surface of the rear cowling 13 portion corresponding to the frame grip 7 is
As shown in the figure, match the bottom surface of the grip 7.
Reference numeral 14 denotes a rear fender, and this fender 14 is attached to the lower surface of a cross member 15 that connects the upper surfaces of the rear ends of the upper frames 5. 16 is a muffler.

17 is a front wheel, 18 is a rear wheel, and 19 is a handle. Next, FIG. 3 is an enlarged side view of the rear body frame, and FIG. 4 is a plan view thereof.

In these figures, the rear body frame B will be described in more detail. The front ends of the upper frames 5 are each connected to the main frame 3 via brackets 20, and the lower front ends of the sub-frames 6 on both sides are connected by a semi-circular cross member 21, The rear parts of the upper frame 5 in front of the member 15 are connected by a cross member 22.

23 is a reinforcing bracket, and this bracket 23
The bent portions of the sub-frames 6 on both sides and the upper frame 5 are respectively coupled.

24 is a reinforcing frame, and this reinforcing frame 24
is the lower surface of the rear end of the right subframe 5 and the subframe 6 in front of the joint with this upper frame 5.
are integrally welded to.

By the way, the motorcycle 1 (first
In Figure 1, a reinforcing frame 24 is provided in place of the frame grip 7 because the muffler 16 (Figure 2) is placed on the right side under the seat 10 (Figure 1) as described above. Yes, but muffler 16
In a type of motorcycle in which the gripper (FIG. 2) is not arranged on the upper part of the rear body frame B, the frame grips 7 may be provided on the upper frames 5 on both sides.

In the motorcycle of this embodiment configured in this manner, when lifting the rear part of the vehicle body such as when standing up, the hand 30 is inserted from under the left rear cowling 13 and the frame grip 7 is lifted up, as shown in FIG. This is done while supporting the bottom surface.

(Effects) As explained above, since the frame grip of this invention has the above-described structure, it can be used in the same way as a conventional sub-grip as a support or grip when lifting the rear vehicle body, and the grip itself can be Since it is integrally welded downward to the lower surface of the upper frame and the lower surface of the sub-frame in front of the joint with this, it greatly increases the supporting capacity of both frames, especially against loads that act in the vertical direction, and also It is possible to strengthen the joint between the parts.

In addition, since the grip is provided on the lower surface of the frame so as to protrude downward, even when the rear cowling is attached, the grip does not get in the way, and the grip can be covered with the rear cowling, which improves the design. It has the effect of being excellent.
