Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a motorcycle handle in which a rubber handle grip is firmly fitted to a gripping portion of a handle pipe. In handles for motorcycles, it is required that the handle grips do not come off or shift during riding, and that the handle grips can be replaced when damaged. Conventional motorcycle handles have been constructed by simply press-fitting a rubber handle grip into a handle pipe, or by applying an adhesive to the handle pipe and press-fitting the handle grip. However, when such conventional motorcycle handles are used for special purposes such as motocross competitions, there is a risk that the handle grip may come off or become misaligned due to a tensile load exceeding a certain level. In order to solve this problem, it is possible to create a protrusion on the handle grip and an engagement hole on the handle pipe so that they fit together, or to attach the handle grip directly to the handle pipe by baking, but each method requires a lot of time and effort in manufacturing. is large. Furthermore, it has not been possible to satisfy the above-mentioned requirements due to the difficulty in replacing the handle grip.

The present invention satisfies the above-mentioned requirements and provides a handle for a motorcycle in which a rubber handle grip can be securely fitted and the handle grip can be replaced without requiring much effort during manufacture.

Embodiments of the present invention will be described below based on the drawings. In FIG. 1, reference numeral 11 denotes a motorcycle handle according to the present invention, and this motorcycle handle 11 has a handle pipe 13 with grip portions 15 formed at both ends thereof. The grip part 15 is a cylindrical body at the end of the metal handle pipe 13,
There is a thin rubber layer 1 all over the outer circumferential surface.
7 is attached by baking. An adhesive is applied to the entire outer peripheral surface of the rubber layer 17, and a bottomed cylindrical rubber handle grip 1 is attached to the handle pipe 13 with the rubber layer 17 interposed therebetween.
9 is press-fitted to fit and adhere.

Note that before the rubber layer 17 is in a vulcanized state,
In the case of adhesive properties, application of such an adhesive is not necessarily necessary.

The handlebar 11 for a motorcycle according to the present invention can be obtained by applying a rubber baking solvent to the gripping part 15 of an unplated metal handle pipe 13, adhering rubber grains thereon, and then heating it. The rubber layer 17 is formed by baking and bonding rubber to the outer circumferential surface of the grip portion 15 of the handle pipe 13. Note that the grip portion 15 of the handle pipe 13
Although the rubber layer 17 can be baked and bonded to the outer circumferential surface of the rubber layer 17 using a conventional mold, the method described above, that is, the method of attaching granular rubber and heating it, is extremely efficient.

FIG. 2 shows another embodiment of the present invention, in which an inner cylinder 27 is rotatably attached to the grip part 15 of the handle pipe 13.
is loosely fitted into the inner cylinder 27, and a locking strip 29 is provided at the front end of the inner cylinder 27.
is formed facing outward. Locking strip 29
A wire groove 31 is bored in a part of the protruding end surface, and an accelerator wire 33 is engaged with this wire groove 31. A thin rubber layer 17 is baked and bonded over the entire surface of the inner cylinder 27 as in the previous embodiment, and an adhesive is applied to the outer peripheral surface of the rubber layer 17 to form a rubber handle grip 19. It is fitted by being press-fitted.

As described above, in the present invention, the rubber handle grip is fitted and attached to the rubber layer baked onto the outer peripheral surface of the metal handle pipe, so the tensile strength of the rubber layer against the handle pipe is increased and the adhesive surface is made of rubber. Due to the close contact, the rubber handle grip is firmly fitted into the metal handle pipe. In addition, when fitting the handle grip onto the handle pipe, there is no need for any special processing on the handle grip or the handle pipe, and manufacturing is easy. Furthermore, since the handle grip is attached to the handle pipe by fitting and pasting the rubber layer, if it becomes necessary to replace it due to damage or the like, it can be replaced by cutting the handle grip. Therefore, the original purpose can be achieved.
