Description

[Detailed Description of the Invention] The present invention provides an operating lever device, more specifically, a grip portion of a handlebar, which is provided with a gap from the outer surface of the grip portion along the length direction of the handlebar, and a lever shaft, The present invention relates to an operating lever device in which an operating portion of the operating lever is supported via the gap so as to swing between the inner and outer sides of the outer surface of the grip portion.

Generally, when an operating lever is supported on a handlebar, a bracket is fixed to the handlebar with a tightening band, and the operating lever is supported on the bracket by a lever shaft. A tightening band is required to fix the bracket to the handlebar, which not only complicates the structure, but also makes it difficult to attach and detach the lever device to the handlebar. Therefore, the length from the palm of the hand that grips the handlebar to the outer surface of the operating lever on which the finger is placed, that is, the grip width is large. As a result, there was a problem of poor operability.

By the way, when supporting the operating lever on the handlebar, it is conceivable to attach the lever shaft directly to the handlebar without using the tightening band and the bracket, but if configured in this way, the lever shaft is attached to the handlebar. Not only does it have to machine a shaft hole to receive the lever shaft, but it also has to be machined to prevent the lever shaft from being accidentally pulled out of the shaft hole, so the structure is still complicated, and the handle of the lever device is There is also the problem that attaching and detaching the bar to the bar is complicated.

The present invention was devised in view of the above-mentioned problems; it eliminates the need for a tightening band, does not require drilling a shaft hole in the handlebar, and can be easily attached to and detached from the handlebar. The present invention aims to provide an operating lever device in which the gripping width of the operating lever can be made small.

That is, the present invention provides a gripping portion of a handlebar with a gap from the outer surface of the gripping portion along the length direction of the handlebar, and also attaches a mounting body having a lever shaft to the gripping portion of the handlebar. a locking portion that is located at an inner portion in the length direction and is fixed inside the handlebar in contact with an inner wall of the handlebar, and that supports a locking body that is fixed to one end of the operating wire on the lever shaft; The operating portion of the operating lever supports an operating lever having a handle bar through the gap so that it swings between the inner and outer surfaces of the grip portion, and the locking portion is connected to the handlebar. It is characterized by being located outward.

Note that the handlebar in the present invention includes not only a handlebar in a narrow sense that is fixed to a handle stem, but also a bar member that is attached to the tip of the handlebar and forms a part of the handle.

Embodiments of the operating lever device of the present invention will be described below based on the drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS What is shown in the drawings is an operating lever device for operating a brake on a bicycle, and is formed by incorporating an operating lever 2 into a handlebar 1 fixed to a handlebar stem (not shown).

The handlebar 1 is formed of a metal pipe, and has a grip section with a gap 1 between the grip section and the outer surface along the length direction as shown in FIG.
1 is formed by a notch, and the operation part of the operation lever 2 is connected to the handlebar 1 through this gap 11.
It is constructed in such a way that it can penetrate into the inside of the body. Incidentally, the gap 11 may be formed not only by providing a notch but also by being recessed.

Further, an operating lever 2 incorporated into the handlebar 1
is supported on the handlebar 1 via a mounting body 4 having a lever shaft 3 that pivotally supports the lever 2. Therefore, the mounting body 4 has two parts facing each other.
A pair of mounting pieces 41, 42 and these mounting pieces 41, 4
2, and the mounting pieces 41 and 42 of the mounting body 4 are provided with shaft holes 44 and 45 for receiving the lever shaft 3,
The lever shaft 3 is supported in these shaft holes 44, 45, and the lever shaft 3 supports the operating lever 2 in a swingable manner on the mounting body 4. Curved lips 41a, 42a protruding from the sides are provided, and these lips 41a,
The distance between the outer surfaces of the connecting piece 42a and the connecting piece 43 is formed to be slightly larger than the inner diameter of the handlebar 1,
The mounting body 4 is fitted into the inside of the handlebar 1 in the longitudinal direction of the handlebar 1 in the grip portion, in contact with the inner wall of the handlebar 1, and the mounting body 4 is fitted into the handlebar 1 in the longitudinal direction. It prevents the operating lever 2 from moving in the swinging direction, and also prevents the mounting body 4 from moving in the swing direction.
Abutments 46 and 47 extending outward from one end of the connecting piece 43 are integrally formed, and when the mounting body 4 is fitted into the handlebar 1, the abutments 46 and 47 are formed integrally with each other.
47 is brought into contact with one end surface in the length direction of the gap 11 to prevent the mounting body 4 from moving to one side in the length direction of the handlebar 1.
The tips of 6 and 47 are extended outward to form a U-shaped support piece 48, and this support piece 48 supports an outer holder to be described later. Furthermore, a mounting hole 1 is provided at one end in the length direction of the gap 11 in the handlebar 1 and in the connecting piece 43 in the mounting body 4.
2 and 49 are provided, and setscrews 5 are screwed into these mounting holes 12 and 49 to fix the mounting body 4 to the handlebar 1. Although the set screw 5 is not necessarily required, the use of the set screw 5 has the advantage that the mounting body 4 can be fixed more reliably.

Further, the operating lever 2 has a locking portion 2 that receives a locking body s fixed to the end of the operating wire W.
1 and a guide groove 22 for guiding the wire W so that the locking body s is supported by the locking part 21 and the operating wire W is guided by the support piece 48 of the mounting body 4. An outer receiver 6 of the outer tube o is supported, and an end portion of the outer tube o is fitted into the outer receiver 6 to support the outer tube o. Then, the locking portion 21 is disposed outside the handlebar 1.

Therefore, in the above configuration, the finger of the hand gripping the grip portion of the handlebar 1 can be used to control the operation lever 2.
When you grasp the operating part of the lever 2 and pull the operating part of the lever 2 toward the gripping part of the handlebar 1, the lever 2
The operating section is centered around the lever shaft 3 as shown in FIG.
As shown by the dotted chain line, through the gap 11,
It swings between the inside and outside of the outer surface of the grip portion, and this swing pulls the operating wire W, allowing the brake to be operated. In the case of FIG. 4, the outer cylinder o is pushed by the swinging of the lever 2, and the brake can be operated.

In this operation, the operating part of the operating lever 2 enters the inside of the grip part of the handlebar 1, so the operating part of the operating lever 2 is inserted between the side surface of the handlebar 1 opposite to the gap 11 side and the lever 2. The length from the outside surface, that is, the grip width can be reduced,
Further, when the lever 2 is attached to or detached from the handlebar 1, it can be done simply by inserting and removing the mounting body 4 that supports the lever 2 from the handlebar 1.

In the above embodiments, the grip is assembled into the handlebar 1, but in addition, a bar member constituting the grip portion of the handlebar 1 is formed separately from the handlebar 1, and the bar member is assembled into the handlebar 1. You can.

As described above, the present invention provides an operation lever on a lever shaft, and an operation part of the operation lever is connected to a grip part of the handlebar through a gap between the grip part and the outer surface of the grip part provided along the length direction of the handlebar. Since it is supported on the outer surface of the grip portion so as to swing between the inner and outer sides thereof, the grip width of the operation portion of the operation lever can be reduced, and the operation lever can be easily operated.
Moreover, the operability can be improved.

Furthermore, since the mounting body having the lever shaft is fixed at the inside portion of the handlebar in the length direction of the grip portion and inside the handlebar in contact with the inner wall of the handlebar, the handle Eliminates the need for a tightening band to secure the bracket to the handlebar, which is required to support the operating lever on the bar.
In addition, there is no need to provide a shaft hole in the handlebar and to irremovably support the lever shaft in the shaft hole, so the structure can be simplified and costs can be reduced. Moreover, since the operating lever can be attached and detached by simply inserting and removing the mounting body from the handlebar, the operating lever can be easily and easily attached to and removed from the handlebar.

Furthermore, since the locking part that supports the locking body fixed to one end of the operating wire is located outside the handlebar, even if the operating wire breaks, it can be easily attached from the outside.

In addition, since the mounting body is fitted and fixed inside the handlebar, the number of parts protruding outward from the handlebar can be reduced, so when applied to a bicycle, the air resistance experienced when riding can be reduced. .
