Description

[Detailed Description of the Invention] This invention relates to a handle attachment structure for vehicles such as motorcycles and tricycles.

Conventionally, a car body was equipped with a front cover (hereinafter referred to as leg shield) that covered the steering stem, and
A steering wheel mounting structure for a vehicle such as a motorcycle that is equipped with a handle cover that covers the handle adjacent to the upper end of the leg shield includes a steering stem that protrudes above the upper end of the leg shield, and a steering stem that is welded to the handle at this protrusion. There is one in which the bracket is tightened with a nut that is screwed into the threaded portion of the upper end of the steering stem via the bracket. However, since this nut is located inside the steering wheel cover, the steering wheel cover had to be attached after the steering wheel was attached to the steering stem. The above structure is disadvantageous in this respect, since it is easier to assemble the handle by attaching the handle to the steering stem while leaving the cover assembled on the handle (that is, with the handle side portion still fully assembled).

This idea was made in view of the above circumstances,
The object of the present invention is to obtain a handle mounting structure that allows the handle cover to be attached to the handle while being subassembled.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic diagram of the front part of the vehicle body of a motorcycle, showing a state in which a handle portion is attached to the vehicle body, and FIG. 2 shows the details thereof. In these figures, 1 is the head pipe, 2 is the body frame connected to the head pipe 1, 3 is the front wheel, 4 is the handle, 5 is the meter, 6 is the headlight, and 7 is the handlebar 4 while housing the meter 5, headlight 6, etc. A steering wheel cover 8 is a front cover of the vehicle body that covers the head pipe 1 and the steering stem 9, that is, a leg shield.

As shown in FIG. 2, the steering stem 9 is inserted into the head pipe 1 and has bearings 1 provided at the upper and lower ends of the head pipe 1.
0 (only the upper end is shown in the figure) and is rotatably supported by the head pipe 1. The length of the steering stem 9 is such that its upper end is located below the upper end of the leg shield 8 by a dimension L as shown in FIG.
It is arranged within the leg shield 8. The leg shield 8 is divided into two parts: a front leg shield 8a and a rear leg shield 8b. The leg shields 8a and 8b are detachably attached to attachment members 15 and 16 fixed to the head pipe 1 by screws 17 and 18, respectively.

On the other hand, a handle post (handle stay) 11 is welded to the center of the steering wheel 4, and includes a collar portion 12a that is fitted to the upper part of the steering stem 9 to prevent rotation, and a bracket that extends forward from the collar portion 12a. The lower part of the handle post 11 is welded to the bracket part 12b of the handle mounting member 12, which is made up of a part 12b. The collar portion 12a of the handle attachment member 12 is fixed to the steering stem 9 by being tightened by a nut 13 that is threaded into a threaded portion at the upper end of the steering stem 9. Note that 14 is a washer. In this embodiment, the handle post 11 is arranged to be parallel to the steering stem 9, but it does not necessarily have to be exactly parallel. Further, the handle cover 7 is attached to a mounting member 19 fixed to the handle 4 with screws 20.

In the steering wheel mounting structure described above, the length of the steering stem 9 is set to be lower than the upper end of the leg shield 8, and the length of the steering stem 9 is set to be lower than the upper end of the leg shield 8.
is not inside the handle cover 7 but in the leg shield 8.
Since the handle cover 7 is located inside the handle 4, the nut 13 can be tightened while the handle cover 7 is attached to the handle 4.

The steps for installing it are explained below.First,
After attaching the meter 5 and the head light 6 to the handlebar 4, attaching the handlebar cover 7 and putting the handlebar part into a subassembled state (that is, after the handlebar side part is in a completed state), attach this to the steering stem 9. . The dimension L in FIG. 2 is large enough to accommodate the tool for tightening the nut 13, and the handle 4 can be attached to the steering stem 9 after small assembly.
Good assembly workability. Next, the front and rear leg shields 8a, 8b are attached to the attachment members 15, 16 with screws 17, 18, respectively.

The installation is now complete. However, because the handle post 11 is positioned eccentrically forward relative to the steering stem 9, the nut 13 can be brought in from the rear side and tightened. Therefore, with the handle, meter, and other parts incorporated into the handle cover 7 and the handle portion sub-assembled, this handle portion can be attached to the vehicle body.

Moreover, the attachment of the handle 4 to the steering stem 9 is performed using the collar portion 12a of the handle attachment member 12.
This is done by the collar section 12.
Since the wall thickness of a can be made sufficiently thick, the handlebar 4 can be attached to the steering stem 9 with sufficiently high rigidity.

Further, although both the leg shields 8a and 8b are attached last, the front leg shield 8a may be attached first in advance because it does not interfere with the tightening work of the nut 13.

Although the handle post 11 in the embodiment uses a pipe, it does not necessarily have to be hollow.
Any member may be used as long as it extends upward and has a length sufficient to position the center portion of the handle 4 above the upper end of the leg shield 8.

As explained above, in the present invention, the steering stem is disposed within the leg shield, the handle stem is protruded from the handle cover, and is placed eccentrically to the steering stem, and the handle stem is attached to the end of the steering stem with a nut or the like. It is characterized by being removably attached using a tightening part.The mounting part is outside the handle cover, and the tightening parts such as nuts can be tightened from the side of the mounting part, so parts such as handles and meters can be tightened. The handle cover can be incorporated into the handle cover, and the assembled handle part can be attached to the vehicle body, which has the effect of improving assembly work efficiency.
