  • Patent number: 6125973
    Abstract: A brake pad holder designed for adjustably mounting a bicycle brake pad to a brake caliper arm. The brake pad holder is designed to maintain the mounting arm thereof in an orthogonal orientation with respect to the brake caliper arm, while the brake pad holder is adjustable in three degrees of motion. The brake pad is removable for repair and replacement thereof, independently from the brake pad mount or other components of the brake pad assembly. The brake pad mount defines a threaded opening for receiving a screw which, when installed, is received within a recess defined by the brake pad. A mounting arm receptor is defined in the bottom wall of the brake pad mount and defines a concave interior configuration which defines a cavity between the mounting arm receptor and the brake pad. A through opening is centrally defined for receiving the mounting arm. The mounting arm is a bolt having a head configured to be received within the cavity defined between the mounting arm receptor and the brake pad.

  • Patent number: 6079523
    Abstract: A bicycle hand brake assembly designed to include minimal parts in order to reduce risk of failure of the entire brake system as a result of failure of one of the parts. The assembly includes first and second brake arms disposed on either side of the bicycle frame. Each of the first and second brake arms defines a lower end which is pivotally mounted to the bicycle frame on either side of a wheel. A brake pad mount is mounted to each of the first and second brake arms for mounting a brake pad thereto via mounting screws such that it may be replaced in the event of failure, or may be reversed to improve clearance and/or generate a varied braking force. The first brake arm defines an upper end terminating above an upper end of the second brake arm, and at an approximate center line of the assembly. The second brake arm terminates at a point approximately above the lower end thereof. A first brake cable slot is defined by the upper end of the first brake arm for receiving a portion of the brake cable.

  • Patent number: 5499698
    Abstract: A small and portable gaping tool in a first embodiment generally comprising a pivotal or hinge connection between two elongated arm members allowing distal ends of the arms to be pivoted toward and away from one another. A connected spring member biases the distal ends of the arms toward one another. The distal end of each arm includes a pivotally supported shim plate extending perpendicular to the arm. With the arms manually pulled into an open or spread position, the shim plates are located one on each oppositely disposed side of a bicycle wheel, wherein the spring member drawing the arms inward secures the tool in place with clamping frictional pressure. The pivotal aspect of the pivotally attached shim plates allow the shims to adjust to varying slopes of different bike wheel sides so as to lay flat thereagainst. The shims are about three millimeters in thickness for example, and are used to shim out the rearward or toe end of bicycle caliper brake pads in adjusting the pads for proper toe-out.
