Abstract

A sequential brake control device for a cycle has a sliding connector and a front delaying and anti-lock spring set to serve to sequentially actuate brake. A left lever cable and a right lever cable are commonly connected to the sliding connector. A front brake cable passes through the sliding connector and the front delaying and anti-lock spring set and is mounted in a front brake cable block abutting against the front delaying and anti-lock spring set. A rear brake cable may alternatively pass through the sliding connector and a rear suspension spring and is mounted in a rear brake cable block abutting against the rear suspension spring. When one or both brake levers are squeezed, a rear wheel is stopped before the front wheel does. The front and rear wheels are slowed down in speed first when a brake is applied and fully stopped at a lower speed of the cycle.

Dependent claims

A sequential brake control device for a cycle adapted to connect to a left brake lever and a right brake lever and adapted to be mounted between a front brake and a rear brake of the cycle, the sequential brake control device comprising:

a housing having:
a top and a bottom;
a chamber defined in the housing;
and
a top cover and a bottom cover respectively covering the top and the bottom of the housing;
a sliding connector movably mounted in the chamber of the housing, being movable in a top-down direction, and having:
a top board having a bottom;
a bottom board having a top;
and
a support frame mounted between the top board and the bottom board;
a front delaying and anti-lock spring set mounted in the sliding connector and having:
a front anti-lock spring having a top end and a bottom end;
and
a front suspension spring mounted in the front anti-lock spring and having a top end and a bottom end;
wherein when the front suspension spring and the front anti-lock spring are mounted in the sliding connector, the bottom ends of the front suspension spring and the front anti-lock spring abut against the top of the bottom board, and the top end of the front suspension spring protrudes beyond a top end of the front anti-lock spring;
a lever control cable set having a left lever cable and a right lever cable, wherein one end of each of the left lever cable and the right lever cable is connected to a corresponding one of the left lever and the right lever, the other end of each of the left lever cable and the right lever cable penetrates through the top cover of the housing, is connected to the top board of sliding connector, and is securely mounted in a corresponding one of the left lever block and the right lever block;
and
a brake control cable set having:
a front brake cable block movably mounted between the top end of the front suspension spring and the bottom of the top board of the sliding connector, abutting against the top end of the front suspension spring, and having a bottom;
a front brake cable, wherein one end of the front brake cable sequentially penetrates through the front suspension spring and the first anti-lock spring of the front delaying and anti-lock spring set, the bottom board of the sliding connector and the bottom cover of the housing to be adapted to connect with the front brake, and the other end of the front brake cable is securely mounted in the bottom of the front brake cable block;
a rear brake cable block mounted on the top of the bottom board and having a bottom;
and
a rear brake cable, wherein one end of the rear brake cable sequentially penetrates through the bottom board of the sliding connector and the bottom cover of the housing to be adapted to connect with the rear brake, and the other end of the rear brake cable is securely mounted in the bottom of the rear brake cable block.
