Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a bicycle brake operating device.

(Prior Art) Generally, a brake operating device used for a bicycle is composed of a fixed member fixed to a handlebar and a brake lever pivoted to the fixed member, and a brake operating device used in conjunction with this brake operating device is Generally, a brake includes a pair of brake arms having brake shoes that come into contact with a wheel rim, and a support member that swingably supports these brake arms.
and a return spring that urges each brake arm toward the return position. Then, using an operating cable consisting of an operating wire and an outer tube that guides the wire, one end of the operating wire is supported on the brake lever, and the other end is supported on one of the brake arms,
One end of the outer cylinder is supported by the fixed member and the other end is supported by the other brake arm, and the return spring tensions the operating cable, so that during braking, the brake lever is moved between the brake shoe and the wheel. When operating the forward stroke amount corresponding to the shoe clearance between the rim and the
The brake arm swings against the return spring, presses the brake shoe against the wheel rim to perform braking, and when the brake is released, when the brake lever is operated to return,
The brake arm returns to its original position by the force of the return spring. That is, in this general brake operation device, when braking, the brake lever must be continuously operated against the return spring for an amount equivalent to the entire preset shoe clearance.

(Problem to be Solved by the Invention) However, when braking is performed using this general brake operating device, the brake lever must be continuously operated for an amount equivalent to the entire shoe clearance set in advance, which makes it difficult to brake especially on long slopes. When descending while descending, a continuous operating force is required to resist the return spring, which causes a problem in that the hand operating the brake lever becomes very easily fatigued.

Furthermore, as disclosed in Japanese Utility Model Application Publication No. 57-50495, an adjustment body that abuts the brake lever is screwed onto the fixing member, and the brake lever is returned to its original position by rotating the adjustment body. BACKGROUND ART A brake operating device is known in which the position, that is, the grip dimension between the brake lever and the handlebar is adjusted.

However, in the case of this conventional brake operating device, when going down a long slope while braking, by operating the adjustment body in advance to reduce the amount of return of the brake lever, the brake shoe can be brought into light contact with the wheel rim, making it slightly Therefore, continuous operation of the brake lever is unnecessary, and operation when going down a slope while braking can be performed easily. Since the clearance can be made smaller, when the brake lever is operated when stopping due to braking,
Although it is possible to stop the brake with a small stroke, this conventional brake operation device returns the brake to the return position by the force of a return spring in the brake by rotating the adjusting body screwed onto a fixed member. Since the return position of the brake lever is changed by forcibly swinging the brake shoe in the direction of the forward position against the return spring, the operation of the adjustment body is very difficult. Moreover, this made it difficult to operate the bicycle with one hand, making it impossible to operate the adjustment body while riding the bicycle, and making it impossible to perform the adjustment operation while descending a slope.

The purpose of the present invention is to adjust the return position of the brake lever.
The purpose is to allow light and easy operation, and also to allow easy operation while riding a bicycle.
