Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a separate type handle for a motorcycle, a motorcycle, or a three-wheeled vehicle (hereinafter referred to as a motorcycle).

(Prior Art) A conventional separate type handle of this type has, for example, a left and right bar holders 13 as shown in FIG.
It is cast and molded separately from, and the insertion hole at the base end of the handlebar 1
The holder 13 is provided with 13a. And handlebar 1
Insert the base end of the into the insertion hole 13a of the holder 13
There is one that welds X around the base end of the handlebar 1 in 3a and fixes it.

As another type, as shown in FIGS. 4 and 5, the sleeve 24 constituting the handlebar 1 insertion hole of the holder 23 is provided with a slit 24a so as to be divided into two, and the upper end of the divided sleeve 24 is stopped. Support piece 25 having an insertion hole 25a for the tool 26
To project. Then, there is one in which the handle bar 1 is fixed by inserting the stopper 26 into the insertion hole 25a and tightening it while the base end portion of the handle bar 1 is inserted into the sleeve 24.

(Problems to be solved by the invention) By the way, each of the conventional handles described above requires a process such as a piercing process for inserting a handle bar, and the manufacturing process is complicated and the cost is high.

The present invention has been made in view of the above-mentioned points, and the handlebar is firmly fixed to the bar holder and does not rotate or come out. An object of the present invention is to provide a separate type handle having no thin portion and no torsion moment acting on the fixed portion of the handlebar.

(Means for Solving the Problem) The gist of the present invention for achieving the above-mentioned object is to separate a motorcycle into which a base end portion of a handlebar is fixed to an insertion hole portion of a bar holder to be integrated. In the mold handle, the handlebar is composed of a straight pipe, and a non-penetrating and circumferentially discontinuous engagement groove is formed on the outer peripheral surface of the base end portion of the handlebar, and a front fork is provided at the bottom. The base end portion of the handlebar and the bar holder are integrated by casting a bar holder having a mounting seat for the.

(Operation) According to the separate type handle of this invention, when the bar holder is cast in the mold, the handle bar can be integrally fixed to the bar holder, and the engaging groove is formed at the base end portion. Since the handlebar is firmly fixed to the bar holder and does not rotate or come off, the engagement groove is not penetrating the outer peripheral surface of the base end portion and is discontinuous in the circumferential direction. Since it is formed on the handlebar, the bending rigidity of the handlebar itself is hardly reduced, and there is no thinned part in the metal thickness around the handlebar after being cast and molded. It is possible to use it for a handle with a strong force, and because there is no thinned portion, it is not necessary to make the cast portion around the base end portion thicker than necessary, which reduces the weight of the vehicle. Near Give.

Further, since the handlebar is linear, even if a force is applied to the handlebar in the circumferential direction, the torsion moment does not act on the fixed portion of the handlebar.

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

FIG. 1 is a front view showing a part of one (left) separate type handle in cross section, and FIG. 2 is a partial perspective view of a handle bar.

In the figure, reference numeral 1 is a pipe-made handlebar, and this handlebar 1 is formed in a linear shape, and the handlebar 1 has a proximal end portion for preventing the handlebar 1 from coming off and preventing rotation. Non-penetrating and circumferentially discontinuous locking grooves 2 are formed in one or several places on the outer peripheral surface.

3 is a bar holder that is cast and molded from an aluminum material or the like. The tool insertion groove 3b is usually formed after casting. The upper end of the holder 3 is formed in the insertion hole 3c at the base end of the bar 1, and the insertion hole 3c and the mounting seat 3a are integrally connected by a support member 3d.

When casting the bar holder 3, the base end of the handlebar 1 is inserted into the mold (not shown) at the molding position of the insertion hole 3c of the bar holder. In this way, by casting the bar holder 3,
The handlebar 1 is integrally connected to the insertion hole 3c of the bar holder 3.

When closing the side of the insertion hole 3c opposite to the side where the handlebar 3 is inserted, another closing member 4 may be fitted after casting as shown in FIG. You can also do it.

(Effect) As described above, since the separate type handle of the present invention has the above-mentioned structure, the handle bar can be integrally fixed to the bar holder when the bar holder is cast in the mold. In this fixing, since the engaging groove is formed at the base end portion, the handle bar is firmly fixed to the bar holder so that it does not rotate or come off, and the engaging groove is not formed on the outer peripheral surface of the base end portion. Since it is a penetrating and discontinuous engagement groove in the circumferential direction, the bending rigidity of the handlebar itself is hardly reduced, and the thickness of the metal around the handlebar after casting is thin. Since there is no part that becomes, it becomes possible to use it for a handle with a considerable force like a motorcycle. Since there is no need to make the cast portion around the base end portion of the handlebar thicker than necessary due to the absence of the thinned portion, the weight of the vehicle can be reduced. Further, since the handlebar is linear, even if a force is applied to the handlebar in the circumferential direction, no torsion moment acts on the fixed portion of the handlebar.

Further, when the bar holder is cast, the handlebar is integrated by casting, so that the work of fixing the handlebar by welding as in the past is unnecessary, and the manufacturing process is simplified.
It is suitable for mass production and can reduce costs.

Moreover, since the handlebar is cast on the bar holder with the engagement groove formed as described above, the handlebar can be used for a motorcycle with a separate handle.
