Description

[Detailed Description of the Invention] The present invention provides an operating lever device, more specifically, a notch in the handlebar along the length direction of the handlebar, and the operating lever can be moved inside and outside the handlebar through the notch. The present invention relates to an operating lever device that is swingably supported between the operating levers.

Generally, when supporting an operating lever on a handlebar, a bracket is fixed to the handlebar, and the operating lever is supported on the bracket by a lever shaft. This requires a lever shaft to support the operating lever, which not only complicates the structure, but also makes it difficult to attach and detach the lever device to the handlebar.Furthermore, there is a problem in that the lever shaft supporting the operating lever is complicated. Therefore, the distance between the palm of the hand that grips the handlebar and the outer surface of the operating lever where the fingers are placed, that is, the grip width, becomes large, which reduces operability. There was also a problem that it was getting worse.

The present invention was devised in view of the above-mentioned problems, and is an operating lever device that eliminates the need for a lever shaft as well as a bracket, allows for easy attachment and detachment from the handlebar, and allows the grip width of the operating lever to be reduced. This is what we are trying to provide.

That is, the present invention provides a gap in the handlebar along the length direction of the handlebar, and supports the operating lever through the gap so as to be able to swing between the inside and outside of the handlebar. , a hook part is formed on the handlebar, and an engaging body having a recessed part that can be engaged with and detached from the hook part is provided at the base of the lever, so that the lever is centered around the hook part of the handlebar. It is characterized by being supported so that it swings.

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

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

What is shown in the drawing is an operating lever device for operating the brakes on a bicycle, and includes a handle system (
Separately from the handlebar 1 fixed to the handlebar (not shown), a bar member 2 constituting the grip portion of the handlebar 1 is formed, and an operating lever 3 is incorporated into the bar member 2. .

Although the present invention may be directly incorporated into the handlebar 1, the use of the bar member 2 is advantageous in that the construction described below can be easily processed.

Therefore, the lever member 2 is provided with a gap 21 along its length as shown in FIG. When the bar member 2 is formed of a pipe, this gap 21 is mainly formed by providing a notch, but it may also be formed by making four other cuts. When the bar member 2 is made of synthetic resin, it may be formed in advance to have a U-shaped cross section.

Then, the following is added to the rubber member 2 configured as above.
It supports the operating lever 3.

The ones shown in FIGS. 1 to 7 have the above-mentioned bar member 2,
The gap 21 is formed by a pipe, the gap 21 is formed by cutting, a through hole 22 is provided on the negative side in the length direction of the gap 21, and a hook portion 23 is provided between the through hole 22 and the gap 21.
At the same time, as shown in FIG. The through hole 22 is penetrated from the inside of the through hole 22, the end surface of the hook portion 23 on the side of the through hole 22 is arc-shaped, and the hook-shaped inner surface of the engaging body 31 is engaged with the arc-shaped end surface of the hook portion 23. , the lever 3 is supported so as to swing around the arc-shaped end surface of the hook portion 23.

Reference numeral 24 denotes a through hole provided on the side surface of the lever member 2 opposite to the side surface forming the gap 21, through which the tip of the base of the operating lever 3 escapes.

In the above configuration, the lever 3 supports the outer receiver 4 of the outer tube O that guides the operating wire W, and the lever 3 is provided at the longitudinal end of the lever member 2 with A wire receiver 5 extending integrally is provided, the wire receiver 5 supports a hook S fixed to the end of the operating wire W, and the end of the outer tube O is fitted into the outer receiver 4. We support them.

One end of the wire W is attached to the brake, and a predetermined tension force is applied by a return spring provided on the brake, so that the lever 3 is moved as shown in FIG. 1 by the tension force of the wire W. is biased clockwise, the front end surface of the lever 3 comes into contact with the front end surface of the gap 21, and the lever 3 is maintained at the position shown in FIG.

The above operating lever 3 is made up of a metal lever main body 33 having length and width 32 and a lever cover 34 made of synthetic resin such as ABS resin, and the lever cover 34 is integrated with the lever main body 33. The front end surface of the portion of the lever main body 33 forming the longitudinal groove 32 is curved in a concave shape, and the outer receiver 4 is supported on this curved portion.

Further, this outer receiver 4 has an insertion hole for the wire W in the center, and a support part 4 for supporting the outer tube 0 in the front part.
1, and a pair of fitting pieces 42, 42 that engage with the longitudinal groove 32 are provided at the rear, and the fitting pieces 42, 42 are fitted into the longitudinal groove 32 as shown in FIG. In the locked state, the lever body 33 is supported by being brought into contact with the curved portion of the lever body 33.

Further, in FIGS. 1 to 3, reference numeral 6 denotes a grip that is fitted onto the outer periphery of the bar member 2 and fixed therein.

Therefore, in the above configuration, the operating lever 3 is gripped with the finger of the hand that grips the grip 6, and the lever 3 is
When pulled toward the bar member 2 side, the lever 3 moves around the arc-shaped end surface of the hook portion 23 of the bar member 2.
It swings as shown by the two-dot chain line in FIG. 1, and this swing pushes the outer cylinder O, allowing the brake to be operated.

In this operation, the operating lever 3 is sent into the inside of the lever member 2, so the length between the side surface of the lever member 2 opposite to the gap 21 side and the outer surface of the lever 3 is In other words, the grip width can be made smaller, and when the lever 3 is attached to or detached from the bar member 2, it can be done by a simple operation of detaching the engaging body 31 of the lever 3 from the hook portion 23. It is.

As described above, in the present invention, a hook is formed on the handle par, and an engaging body having a recess that can be engaged with and detached from the hook is provided at the base of the lever.
Since the handlebar swings around the hook part of the handlebar, it is possible to eliminate the need for not only a bracket but also a lever shaft, simplifying the structure and providing it at low cost. The lever can also be easily attached and detached.

Moreover, since the bundle bar is supported so as to swing between the inside and outside of the bundle bar through the gap provided in the bundle bar, the grip width of the lever can be reduced and the operability can be improved.Furthermore, since no bracket is used, Since the number of members protruding outward from the bundle bar can be reduced, when applied to a bicycle, the air resistance experienced during riding can also be reduced.
