Abstract
The disclosure provides for torsionally resilient interconnection structure of two existing bicycles into side-by-side or parallel cooperative relationship, by employing plurality of torsionally resilient connecting members which are bent to form a longer mid-portion and two shorter end portions, with their longer mid-portions positioned substantially horizontally and transversely between the main frame tubes of the two bicycles, and their shorter end portions aligning longitudinally with the correspondingly positioned frame tubes of the two bicycles and operatively attached to them at two spaced-apart points, including novel steering linkage and front wheels tie-rod system allowing the two coupled bicycles to be operated as one four-wheel vehicle and enabling it to carry additional people and cargo.
Claims71
A torsionally resilient interconnecting structure for coupling two compatibly configured bicycles into side-by-side parallel relationship for simultaneous operation as a single four-wheel vehicle comprising:
- (1) a plurality of specifically configured cross members each bent to form a longer mid-portion and two shorter end-portions;
- said longer mid-portions positioned substantially horizontally and transversely between the coupled bicycles with said shorter end-portions being aligned with correspondingly positioned frame tubes of said bicycles and being attached to said frame tubes at two spaced apart points along each aligned section;
- and (2) a modified trapezium steering linkage operatively interconnecting conventional steerable front wheels of said bicycles enabling the vehicle to be efficiently steered from either one of said bicycles.
