Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
201 words
Apparatus for coupling two bicycles, each having a frame including a seat tube, pedals and a handlebar stem for simultaneous operation in spaced side-by-side relation, comprising: at least one rigid longitudinally adjustable frame connector having clamp means at its respective ends adapted to extend between and be connected with a normally horizontal portion of the respective bicycle frame; a seat tube bracket adapted to be connected with the seat tube of each bicycle, said seat tube brackets each having a forwardly projecting normally horizontally disposed rod portion; a rigid longitudinally adjustable seat tube connector having a sleeve bearing transversely connected with its respective ends for surrounding the respective said horizontal rod portion; steering connector means adapted to interconnect the handlebar stems of said bicycles for simultaneously angular displacement of the front wheels whereby said bicycles are constrained to turn in unison; and, a longitudinally adjustable pedal connector having a U-shaped member connected with its respective ends adapted to receive a pedal of each said bicycle when the pedals are disposed in aligned opposition for maintaining the angular rotation of the bicycle wheels constant with respect to each other whereby said bicycles are restrained from advancing or receding relative to each other.
Claim 2
Dependent Claim
201 words
Apparatus for coupling two bicycles, each having a frame including a seat tube, pedals and a handlebar stem for simultaneous operation in spaced side-by-side relation, comprising: at least one rigid longitudinally adjustable frame connector having clamp means at its respective ends adapted to extend between and be connected with a normally horizontal portion of the respective bicycle frame; a seat tube bracket adapted to be connected with the seat tube of each bicycle, said seat tube brackets each having a forwardly projecting normally horizontally disposed rod portion; a rigid longitudinally adjustable seat tube connector having a sleeve bearing transversely connected with its respective ends for surrounding the respective said horizontal rod portion; steering connector means adapted to interconnect the handlebar stems of said bicycles for simultaneously angular displacement of the front wheels whereby said bicycles are constrained to turn in unison; and, a longitudinally adjustable pedal connector having a U-shaped member connected with its respective ends adapted to receive a pedal of each said bicycle when the pedals are disposed in aligned opposition for maintaining the angular rotation of the bicycle wheels constant with respect to each other whereby said bicycles are restrained from advancing or receding relative to each other.
Claim 3
Dependent Claim
56 words
The apparatus according to claim 1 in which said steering connector means includes: a split clamp surrounding the respective said handlebar stem; and, an L-shaped shaft pivotally connected, at one end portion, with one portion of said split clamp for vertical pivoting movement of the other end portion of said L-shaped shaft about a horizontal axis.
Claim 4
Dependent Claim
31 words
The apparatus according to claim 2 in which said connectors each include internally threaded tubular end portions, and a threaded shaft extending between and connected with the respective tubular enD portion.
Claim 5
Dependent Claim
28 words
The apparatus according to claim 3 in which the U-shaped members of said pedal connector are hingedly connected with the respective tubular end portion of said pedal connector.
