Pipe joining construction of a bicycle frame
摘要:
A pipe joining construction includes a tube (10; 12; 14; 16), two or more extensions (210; 220) extended from the tube (10; 12; 14; 16), a tube member (10; 12; 14; 16) coupled to each of the extensions (210; 220) so as to form a joint portion, an insert (30) disposed in each of the tube members (10, 12, 14, 16) and the extensions ( 210; 220) and having an envelope (31) and a foamable material (32) disposed in the envelope (31), a covering having an outer layer (40) wrapped around the joint portion and a foamable material (41) disposed between the outer layer (40) and the joint portion. When foamed, the foamable materials (32, 41) apply forces against the tube members (10, 12, 14, 16) and the extensions (210, 220) so as to solidly couple them together.
