Abstract
In a bicycle frame wherein a plurality of frame members are selectively joined together at the ends thereof, each of the joints which support the head tube, the seat and the crank housing is a lug joint consisting of a plurality of organic fiber layers partially wrapping the joined end portions of the frame members, the fibers composing each layer being oriented at different angles from the fibers in the adjacent layers, and all of these sheets being impregnated with resin which hardens to secure the sheets to the frame members. Web portions of these fiber layers also enclose a portion of the space between wrapped portions of the frame members, and each of these spaces is filled with a suspension of microballoons in hardened resin which cooperates with the web portions of the fiber layers to brace the joined frame members against movement toward each other during use of the bicycle. The production of bicycle frames in accordance with the invention is expedited by utilizing, as the resin component of each joint, a two-part resin which sets by exothermic reaction at room temperature and thus eliminates need for heat treatments such as are required in the case of thermosetting resins, brazing and other such manufacturing procedures.
