Abstract
An improved radial braking system uses the power of the cyclist's back pedaling to bring the braking member into contact with the rim of the wheel. The system allows for the direct contact of the braking member with the middle portion of the outer surface of the rim rather than to the side of the rim, as is common with the caliper type brakes. A rim having a laterally disposed lip for mounting of the spoke allows for an unobstructed middle portion for contact with the braking member.
Claims9
For use with a bicycle, including a frame, wheel forks, wheels having rim and hub members and being rotably mounted in said wheel forks, sprocket and chain means for imparting rotation to at least one of said wheels, pedal means rotably mounted to said frame in operative relation with said sprocket and chain means to impart forward rotation to said sprocket upon forward pedaling of the cyclist:
- A. an improved radial braking system which comprises:
- 1. a brake member mounted near the outer surface of one of said rim members, but normally out of contact therewith;
- 2. motion translation means, in operative relation with said brake member, for moving said brake member into braking engagement with the rim member;
- 3. power means in operative relation with said motion translation means to impart motion to said motion translation means;
- 4. said rim member comprising:
- a. an unobstructed middle portion for the provision of maximum braking surface;
- b. two wall portions;
- and
- c. a laterally-disposed lip portion, said lip portion extending laterally of one of said wall portions, and
- d. spoke members radiating from said laterally-disposed lip portion.
For use with a radial braking system, an improved rim and spoke combination comprising a rim having:
- A. an unobstructed middle portion for the provision of maximum braking surface;
- B. two wall portions;
- and
- C. a laterally-disposed lip portion, said lip portion extending laterally of one of said wall portions;
- and
- D. spoke members radiating from said laterally-disposed lip portion.
