Abstract
The present invention relates to an apparatus for adjusting biasing springs in a cantilever brake. A conventional apparatus for adjusting the biasing springs includes disks each engaging one leg of each spring, and adjusting screws each meshed with a proximal end of a brake caliper for contacting one of the disks. In the present invention, each biasing spring is engaged with a spring cover to which an adjusting screw is attached.
Claims25
A brake assembly for attachment to a bracket fixed to a bicycle comprising:
- a brake caliper for pivotally mounting to said bracket;
- a cover for pivotally mounting to said bracket between said brake caliper and said bracket, wherein said cover is movable relative to said brake caliper;
- a biasing spring having a first leg attached to said cover and a second leg for attachment to said bracket;
- a screw holder formed on said cover;
- an adjusting screw meshed with said screw holder;
- and
- a contact portion formed on said brake caliper for contacting said adjusting screw.
A brake assembly for attachment to a bracket fixed to a bicycle comprising:
- a brake caliper for pivotally mounting to said bracket, wherein said brake caliper pivots about an axis;
- a cover for pivotally mounting to said bracket with said brake caliper, wherein said cover is movable relative to said brake caliper;
- a biasing spring having a first leg received by said cover and a second leg, the biasing spring being attached so that, when said cover moves relative to said brake caliper, a biasing force of said biasing spring applied to said brake caliper is varied;
- and
- wherein said cover has a generally cylindrical shape and has a portion defining a bore for receiving said first leg of said spring.
