FRAME JOINT CONSTRUCTION FOR BICYCLES AND THE LIKE

摘要

A frame joint for bicycles and the like includes a stub insert consisting of a base, a stub protruding from the base, and an annular shoulder at the junction between the base and the stub; a connecting member having a tubular end with an annular end face telescoping over the stubin a press fit; adhesive bonding the tubular end to the stub; and an annular collet positioned on the stub between the end face and the shoulder. The collet includes an inner end having a first lip portion which extends about and overlaps a periphery of the base adjacent to the shoulder and an outer end having a second lip portion which is beveled in a concave fashion to overlap and receive the end face of the connecting member. The first and second lip portions are joined by a continuous outer wall having a diameter greater than that of the tube end and the base, and an interior wall extending between the first and second lip portions having a diameter less than that of the tube end and base.
