Abstract

PURPOSE:To prevent breakage of an operational lever in the event of falldown by interposing a spring-energized bearing between an accommodation part, which is formed at a seat ring part in the necessary part of a handle bar, and a supporting part formed at a bracket of the operational lever. CONSTITUTION:At a handle bar 4, a seat ring part 1 having a width the same as a bracket 2 for operational lever and an outside dia. greater than the handle bar 4 is formed at the mounting position for the bracket, and circumferential ridges 3 are provided at the two circumferential edges of this seat ring part. A number of bearing accommodation parts 5 are provided at a constant spacing at the periphery of the seat ring 1. In each accommodation part 5, a spring 9 is interposed between an upper tapered portion 5a and a bottom wall 5b. At the inside surface of the bracket 2, a bearing supporting recess 7 is formed as mating with each accommodation part 5. A bearing 6 is accommodated between these accommodation part 5 and supporting recess 7, supported, and energized outward.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a device for supporting a bracket of a clutch lever or a front brake lever in a two-wheeled vehicle to a handlebar.

(Prior Art) Conventionally, as shown in Fig. 5, a clutch lever or a front brake lever in a two-wheeled vehicle is made by dividing an annular bracket into two half-arc shapes, and holding a handlebar between each bracket piece. The bracket pieces were held in place and fixed by screwing male screws into female screw portions protruding from both ends of these bracket pieces.

Furthermore, in two-wheeled vehicles, riding posture changes depending on individual differences such as height, so when adjusting the clutch lever and front brake lever to angles suitable for each individual's operation, it is necessary to adjust the outer circumference of the handlebar. (Problem to be Solved by the Invention) However, according to the above conventional mounting method, the inner circumferential surface of the bracket is aligned with the outer circumferential surface of the handlebar by screwing. Since the lever is fixed by being pressed against the lever, in the event of a two-wheeled vehicle falling over, the lever may be hit hard against the road surface, causing it to break or become bent. Furthermore, when a single two-wheeled vehicle is used by multiple drivers, the position of the female thread on the outer circumferential surface of the handlebar must be determined each time the bracket is adjusted to an angle suitable for each individual's lever operation. It was rather troublesome.

In view of such difficulties, the present invention can prevent breakage or bending of the lever due to accidents such as overturning of two-wheeled vehicles, and
It is an object of the present invention to provide a support device for a handle and a bracket that allows the angle of a lever to be easily adjusted.

[Structure of the Invention] (Embodiment) To explain the following based on the embodiment of the drawings, as shown in FIG. A seat ring portion 1 is formed which is larger than that of the handlebar 4, and ridge rings 3 are provided protruding from both peripheral edges of this seat ring portion 1 to serve as a stopper.

As shown in FIG. 2, perpendicular to the central axis of the handlebar 4, a plane dividing the seat ring part 1 into equal parts intersects with the outer circumferential surface of the seat ring part 1 by 60 degrees. Cylindrical bearing housing portions 5 are provided in grooves at intervals of . As shown in FIG. 3, each of the bearing housing parts 5 has an upwardly tapered part 5a at the top edge thereof, and a tapered part 5a which is tapered upward is provided between the bottom wall 5C and the stored bearing 6. A spring 9 energized is interposed therebetween, so that the bearing 6 protrudes from the top opening of the bearing storage portion 5 with a sub-arc curved surface that is pressed outward.

As shown in FIGS. 2 and 3, bearing support concave portions 7 corresponding to the top openings of the bearing storage portions 5 are provided on the inner peripheral surface of the bracket 2 at intervals of 30 degrees. Install grooves.

As described above, the handle and bracket support device for a two-wheeled vehicle according to the present invention is constructed.

In the above embodiment, the bearing storage portion 5 is provided in the seat ring portion.
B in which the bearing support concave portion 7 is grooved on the other bracket.
However, in the reverse embodiment, the bearing support concave portion 7 is provided in the seat ring portion, and the bearing storage portion 5 is provided in the other bracket.
Aa with a groove! can also be considered.

(Function) As shown in FIG. 4, the annular bracket 2 is divided into half arcs, and the seat ring portion 1 is held between each bracket piece 2a, 2b. The male threads are screwed onto the female threads at both ends of the bracket 2, and the bearing 6 is recessed into the bearing storage part 5 against the urging force of the spring 9. Place it in place in a pressed state. At this time, the lever 80
The angle can be adjusted as in the conventional case by using the bracket pieces 2a,
The bracket 2 is slid and rotated with respect to the seat ring l without depending on the positioning of the female threads at both ends of the bracket 2b, and the six bearings 6 are adjusted to an angle suitable for each individual's operation. The bracket 2 is supported by fitting into six of the twelve bearing support concave curves 7 provided on the inner circumferential surface of the bracket 2.

If the lever 8 is hit hard against the road surface during a fall accident of a two-wheeled vehicle, even if a force is applied to the lever 8 to rotate it around the handlebar 4, it may break or break due to the following reasons. can be avoided. That is, the bracket 2 is supported by the bearing 6 on the seat ring portion 1 of the handlebar 4, and the pressing force of the six bearings 6 is greater than the force that would break or bend the lever 8. Since the brackets 2 are small, the bracket 2 slides and rotates around the outer periphery of the seat ring portion 1 while recessing them into the bearing housing portion 5. At this time, since ridge rings (stoppers) 3 are provided on both peripheral edges of the seat ring portion 1, the bracket 2
does not come off from the seat ring l. Therefore, although the angle setting of the lever 8 may be incorrect, the lever 8 itself will not break or become bent. This deviation in angle setting can be immediately corrected by manually sliding and rotating the bracket 2 and readjusting it.

[Effects of the Invention] According to the handlebar and bracket support device for a two-wheeled vehicle of the present invention, it is possible to prevent breakage or bending of the lever due to a fall accident of the two-wheeled vehicle, etc.
The angle of the lever can be easily adjusted.
