Description

[Detailed description of the invention] This invention consists of a pair of handle holders protruding from a top bridge that connects the upper ends of a pair of front forks of a motorcycle, and an upper holder that is screwed onto the upper end surface of the handle holders. The present invention relates to an attachment structure for a handle cover that covers a portion of the handle pipe located between both handle holders in a motorcycle having a fixed handle pipe.

The above-mentioned steering wheel cover is attached between the steering wheel holders with the main purpose of improving the appearance of the steering wheel mounting part, but it can be used as a set with the key inserted into the combination switch located in front of the steering wheel pipe, and can be used as a spare key. It also prevents the handle pipe from being damaged by key chains, etc.

1 to 3 show an example of a conventional motorcycle equipped with such a handle cover.

Figure 1 is a side view of a motorcycle, where 1 is a headlamp;
2 is the meter panel, 3 is the combination switch, 4
5a is a front fork, 5a is a head pipe of the vehicle body frame 5, 6 is a top bridge that connects the upper ends of the left and right front forks 4, and 7 is a handle pipe, and this handle pipe 7 is formed to protrude from the top bridge 6. It is fixed between a pair of left and right handle holders 8 and an upper holder 9 bolted to the upper part of the handle holders 8.

A handle cover 10 that covers the upper part of the handle pipe 7 located between the pair of handle holders 8 is attached to a boss portion 6a that is integrally attached to the top bridge 6 via a bolt 11 as shown in FIGS. 2 and 3. It is screwed on.

However, with such a mounting structure □, it is necessary to form a boss portion 6a on the top bridge 6 and provide bolt holes in the boss portion 6a, so the top bridge 6
There is a problem that not only does the number of man-hours for manufacturing the handle cover 10 increase, but also that the efficiency of assembling the handle cover 10 is poor due to the troublesome installation work of bolting.

Therefore, handle covers as shown in FIGS. 4 and 5 have been proposed.

The handle cover 12 shown in FIG. 4 is integrally molded from synthetic resin, and a cover portion 12a and a portion of the flange portion 12b that sandwich the handle pipe 7 from the front and back are integrated.

In the one shown in FIG. 5, a groove 13a into which the handle pipe 7 fits is formed in the lower part of a block 13 made of rubber or the like.

The components shown in FIGS. 4 and 5 can be easily installed by simply inserting them into the handle pipe 7 from above, so the efficiency of the assembly work can be improved.
On the other hand, since it is easy to remove, there is a problem in that it is sometimes stolen by mischief.

This idea was created in consideration of the above circumstances, and requires minimal processing on the top bridge of a motorcycle, and provides a structure for attaching a handle cover that can be easily installed but cannot be easily removed. The purpose is to

Hereinafter, one embodiment of the present invention will be described based on FIGS. 6 to 8.

In these figures, parts that function in the same way as those shown in FIG. 2 are given the same numbers to simplify the explanation.

In this embodiment as well, the handle pipe 7 includes a pair of handle holders 8 formed to protrude upward from the top bridge 6 as in the conventional case, and an upper holder 9 fixed to the upper part of the handle holders 8 via bolts 14. However, at the front and back (top and bottom in FIG. 6) of the upper end surface 8a of the handle holder 8, there is a stepped part 8b that is recessed from the surroundings and faces the side where both the handle holders 8, 8 face each other. This stepped portion 8b forms a groove portion 15 between the handle holder 8 and the upper holder 9 that opens on the side where both the handle holders 8, 8 face each other.

The handle cover 16 that covers the upper part of the handle pipe 7 located between both handle holders 8, 8 includes a ceiling part 16a that covers the upper part of the handle pipe 7, and front and rear walls that extend downward from the front and rear ends of this ceiling part 16a. a portion 16b, a side wall portion 16c extending downward from both ends (left and right ends in FIG. 6) of the ceiling portion 16a, and a side wall portion 16c extending downward from approximately the center of the ceiling portion 16a and sandwiching the handle pipe 7 in the front-rear direction. A pair of flange portions 16d for positioning are integrally molded from an elastic material such as synthetic resin, and the side wall portion 16c is formed with a notch 16e opening downward through which the handle pipe 7 is inserted. Locking pieces 16f that protrude into the groove 15 are formed at front and back positions sandwiching the notch 16e.

This locking piece 16f is selected so that the length dimension protruding into the groove 15 is larger than the gap C between the handle holder 8 and the handle cover 16, and the upper surface A is horizontal and the lower surface B is It is formed to be inclined upward from the base end to the distal end.

Further, the gap between the pair of flange portions 16d becomes narrower as it goes upward, and the locking piece 16f is connected to the groove portion 15.
The dimensions are set so that a slight biasing force acts upward in the fitted position.

After bolting the handle pipe 7 through the upper holder 9, the handle cover 16 formed as described above is pushed into the handle pipe 7 side from above as shown by arrow A in FIGS. 7 and 8. .

When the inclined lower surface B of the locking piece 16f comes into contact with the upper end of the upper holder 9, part of the force pushing the handle cover 16 downward acts as a force pushing the both side walls 16c from both sides, and the side walls The portion 16c is elastically deformed inward,
The locking pieces 16f on both sides fit between both handle holders 8,8.

Furthermore, push down the handle cover 16 and lock the locking piece 1.
When the handle 6f reaches the groove 15, the locking piece 16f protrudes into the groove 15 due to the elasticity of the side wall 16c, and the handle cover 16 is fixed between the handle holders 8, 8.

In this way, the handle cover 16 is attached to both handle holders 8
, 8, the handle cover 16
Even if an upward force is applied to the locking piece 16f, the engagement between the locking piece 16f and the groove portion 15 will not come off because the upper surface A of the locking piece 16f is horizontal.

When removing the handle cover 16, remove the bolt 1.
4 and remove the upper holder 9 fixed to one handle holder 8, or use a tool that can be inserted into the gap C to elastically deform the side wall portion 16c and remove the upper holder 9 from the groove portion 1.
5, the locking piece 16f may be released.

Normally, the top bridge 6 is often formed by casting or the like using a mold that is divided into upper and lower parts, but as mentioned above, a step part 8b is formed on the upper end surface of the handle holders 8, 8.
If the groove 15 into which the locking piece 164 fits is formed between the upper holder 9 and the handle holder 8 by the stepped portion 8b, the stepped portion 8b can be obtained at the same time when the top bridge 6 is molded. Especially the groove part 15
There is no need for additional labor-intensive processing to obtain the desired results.

Therefore, the processing performed on the top bridge can be done in the same way as conventional methods, and there will be no inconvenience in terms of reducing processing costs.

Furthermore, as described above, if the lower surface B of the locking piece 16f is inclined, part of the force pushing the handle cover 16 downward when the handle cover 16 is attached is absorbed by the cover 1,
Since the force is converted into a force that deforms the side wall portion 16c of No. 6 inward, the cover 16 can be assembled with a small amount of force.

In the above-described embodiment, the handle cover 16 is a simple box-shaped one that is open at the bottom, but it may be shaped to accommodate small items such as fuses.

As explained above, the handle cover mounting structure of the present invention is provided with locking pieces that protrude toward the handle holder on both sides of the handle cover, and these locking pieces are screwed to the handle holder and the handle holder. The handle cover is fitted into a groove formed in the mating part with the upper holder, and the lower surface of the locking piece is sloped upward from the base end to the distal end, so that the handle cover fits into the pair of handle holders. It can be easily and firmly attached between a pair of handle holders by simply pushing it lightly between them.

Further, the groove formed at the joint between the handle holder and the upper holder utilizes a step formed on the upper end surface of the handle holder, and the step can be obtained at the same time as casting the top bridge.

Therefore, no special labor-intensive machining is required to obtain the grooves, and no inconvenience occurs in terms of reducing machining costs.

Furthermore, if the upper holder is provided with a stepped portion, there is a risk that the upper holder may be installed with the stepped portion facing the opposite side when the upper holder is assembled to the handle holder. If this is provided, there is no such risk, and good results can be obtained in terms of assembly workability.

Furthermore, removing the handle cover requires work such as removing the screws fixing the upper holder, and it cannot be removed simply by pulling.

Therefore, the effect of preventing theft due to mischief is also increased.
