Latest Patents

One of Ishibashi's latest patents is a caliper brake for bicycles. This innovative design features brake members formed as side-pull type caliper arms, which are pivotally supported on the bicycle frame. The brake members support brake shoes at their ends, and a pulley is rotatably provided on the free end of one of the brake members. The brake operating wire consists of an inner wire and an outer wire, with the inner wire extending about the pulley to create a brake operating force acting point. This design minimizes the operating radii between pivotal points of both brake members and the brake operating force acting points. Another patent involves a caliper type brake that includes brake members shaped like bell cranks, which are also pivotally supported by the bicycle frame. This design further optimizes the operating radius to enhance braking efficiency.
