摘要： A method and apparatus for coupling tubular elements (12, 14, 16, 18, 20 and 22) of a frame (10) without welding or adhesive bonding. Connection elements (24, 26 and 28) are used with which mechanical connections may be accomplished by relatively deforming one of the connection elements and its respective tubular element. Preferably, the connection element (24, 26 and 28) is shaped to be inserted within a hollow end of a tubular element and includes radially inwardly directed recesses (46). The tubular element is deformed with respect to the recesses, preferably by electromagnetic pulse forming, to thereby lock the tubular element and connection element (24, 26 and 28) against relative movement. Such connection elements and method may be used in frames of mobile units such as bicycles (200), wheelchairs (110), and walkers. The forming process used in connecting the tubular frame elements may also be used to create ride compliance features in the frame by deforming at least one of the tubular elements to modify its spring constant. The ride compliance features preferably are radially inwardly or outwardly circumferential deformations.

摘要： A method of forming a tubular frame, e.g., a bicycle frame (10), from two substantially symmetrical frame-halves (12, 14) utilizes a plurality of interconnected half-tubular elements. Each half-tubular element has an exterior surface (18), an interior surface (16), and longitudinal edges (20) that extend between the exterior and interior surfaces in the direction of the longitudinal axis of the half-tubular element. The surfaces of the longitudinal edges are shaped such that corresponding edges of corresponding elements in the left and right half-frames may easily be interengaged, and adjusted along the respective longitudinal axes of the half-tubular elements that are being joined. The longitudinal edge of one of the elements may include a radial step or parallel steps (26, 46) extending in opposite directions to thereby form a groove into which a step of the corresponding longitudinal edge of the corresponding element on the half-frame may be inserted. Further reinforcement in the stay area of the bicycle frame may be provided, either in the form of a reinforcement arch (80) positioned within the tubular legs of the stays, or in the form of a one-piece, unitary inner stay element (110) positioned between the outer stay elements that are part of the frame-halves.
