WebCPC CPC COOPERATIVE PATENT CLASSIFICATION

B62L　BRAKES SPECIALLY ADAPTED FOR CYCLES {(arrangements in cycles for adjusting wheel-braking force to meet varying vehicular or ground-surface conditions B60T 8/00)}

　　NOTE - This subclass covers only adaptations of brakes and their actuating mechanisms peculiar to their use on cycles.

　　This subclass does not cover brakes or actuating mechanisms of wider applicability, which are regarded as of general type, irrespective of whether described or claimed only for cycles, which are covered by subclass B60T or the relevant subclass of F16.

B62L 1/00 Brakes {(back-pedalling brakes B62L 5/00)}; Arrangements thereof

B62L 1/005 ・{constructional features of brake elements, e.g. fastening of brake blocks in their holders}

B62L 1/02 ・in which cycle wheels are engaged by brake elements

B62L 1/04 ・・the tyre surfaces being engaged

B62L 1/06 ・・the wheel rim being engaged

B62L 1/08 ・・・by the elements moving radially relative to the wheel

B62L 1/10 ・・・by the elements moving substantially parallel to the wheel axis

B62L 1/12 ・・・・the elements being mounted on levers pivotable about a common axis

B62L 1/14 ・・・・the elements being mounted on levers pivotable about different axes

B62L 1/16 ・・・・・the axes being located intermediate the ends of the levers

B62L 3/00 Brake-actuating mechanisms {(for back-pedalling brakes B62L 5/00)}; Arrangements thereof

B62L 3/02 ・for control by a hand lever (hand lever for control of cycles in general B62K 23/06)

B62L 3/023 ・・{acting on fluid pressure systems}

B62L 3/026 ・・{actuation by a turning handle or handlebar}

B62L 3/04 ・for control by a foot lever (foot levers for control of cycles in general B62K 23/08)

B62L 3/06 ・Means for locking the actuating mechanisms (locking a cycle braking device directly B62H 5/18)

B62L 3/08 ・Mechanisms specially adapted for braking more than one wheel

B62L 5/00 Brakes, or actuating mechanisms therefor, controlled by back-pedalling (free-wheel devices specially adapted for cycles F16D 41/00)

B62L 5/003 ・{the brakes being arranged apart from the rear wheel hub}

B62L 5/006 ・{Details}

B62L 5/02 ・the brakes being actuated through coacting coaxial cones {located in the rear wheel hub}

B62L 5/04 ・・the brakes being of expanding brake-bushing type

B62L 5/06 ・・the brakes being of disc type

B62L 5/08 ・・the brakes being of shoe type

B62L 5/10 ・the brakes being actuated through coacting cams and balls or rollers {located in the rear wheel hub}

B62L 5/12 ・・the brakes being of expanding brake-bushing type

B62L 5/14 ・・the brakes being of disc type

B62L 5/16 ・・the brakes being of shoe type

B62L 5/18 ・the brakes being additionally controlled by alternative means
