Abstract
Abstract Interconnecting bars are employed to connect two standard bicycles in a side-by-side relationship. The bicycles are interconnected adjacent the respective rear axles thereof, adjacent their respective seats and adjacent the front of the frames thereof, for stabilizing the bicycles and are also interconnected at their respective steering mechanisms with a tie rod that is adjustable to allow setting of wheel toe-in for proper steering and handling characteristics.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
234 words
An apparatus for interconnecting a pair of bicycles comprising: a) a pair of bicycles positioned in a side-by-side relationship, each of said pair of bicycles having a frame, a rear wheel axle, a seat and a steering mechanism; b) a first interconnecting bar extending between said pair of bicycles and coupled on the opposite ends thereof to the frames of said bicycles adjacent the rear wheel axles thereof; c) a second interconnecting bar extending between said pair of bicycles and coupled on the opposite ends thereof to said pair of bicycles adjacent the seats thereof, said second interconnecting bar comprising, a V-shaped hollow tubular member a portion intermediate the opposite ends of which is connected to said first interconnecting bar, a rod axially slidably mounted in each of the opposite ends of said V-shaped hollow tubular member for adjusting the length of said second interconnecting bar, each of said rods coupled to a different one of said pair of bicycles, and means on said V-shaped tubular member for optionally allowing axial sliding movement of said rods relative to said V-shaped tubular member; and means extending between the steering mechanisms of said pair of bicycles and connected thereto for causing the steering mechanisms to turn in unison, said means for interconnecting the steering mechanisms of said pair of bicycles being adjustable for setting the toe-in relationship of the steering mechanisms of said pair of bicycles.
Claim 2
Independent Claim
234 words
An apparatus for interconnecting a pair of bicycles comprising: a) a pair of bicycles positioned in a side-by-side relationship, each of said pair of bicycles having a frame, a rear wheel axle, a seat and a steering mechanism; b) a first interconnecting bar extending between said pair of bicycles and coupled on the opposite ends thereof to the frames of said bicycles adjacent the rear wheel axles thereof; c) a second interconnecting bar extending between said pair of bicycles and coupled on the opposite ends thereof to said pair of bicycles adjacent the seats thereof, said second interconnecting bar comprising, a V-shaped hollow tubular member a portion intermediate the opposite ends of which is connected to said first interconnecting bar, a rod axially slidably mounted in each of the opposite ends of said V-shaped hollow tubular member for adjusting the length of said second interconnecting bar, each of said rods coupled to a different one of said pair of bicycles, and means on said V-shaped tubular member for optionally allowing axial sliding movement of said rods relative to said V-shaped tubular member; and means extending between the steering mechanisms of said pair of bicycles and connected thereto for causing the steering mechanisms to turn in unison, said means for interconnecting the steering mechanisms of said pair of bicycles being adjustable for setting the toe-in relationship of the steering mechanisms of said pair of bicycles.
Claim 3
Dependent Claim
39 words
An apparatus as claimed in claim 1 further comprising a third interconnecting bar extending between said pair of bicycles and coupled on the opposite ends thereof to the frames of said pair of bicycles adjacent the forward ends thereof.
Claim 4
Dependent Claim
19 words
An apparatus as claimed in claim 1 further comprising an article carrying basket supported on said first interconnecting bar.
Claim 5
Dependent Claim
62 words
An apparatus as claimed in claim 1 wherein said first interconnecting bar comprises: a. an elongated tubular member of fixed length the opposite ends of which are demountably coupled to said pair of bicycles; and b. a plate affixed to the upper surface of said elongated tubular member substantially intermediate the opposite ends thereof upon which an article carrying basket is mountable.
Claim 6
Dependent Claim
90 words
An apparatus as claimed in claim 1 wherein said means for interconnecting the steering mechanisms of said pair of bicycles comprises: a. a pair of cranks each of which is attached to a different one of the steering mechanisms of said pair of bicycles, each of said cranks having an extending end; and b. a tie rod of adjustable length pivotably connected on each of its opposite ends to the extending of said pair of cranks so that the steering mechanisms of said pair of bicycles will turn in unison.
Claim 7
Dependent Claim
60 words
An apparatus as claimed in claim 5 wherein said tie rod comprises: a. a hollow tubular member; b. a rod axially slidably mounted in said hollow tubular member for adjusting the length of said tie rod; and c. means on said hollow tubular member for optionally allowing the axial sliding movement of said rod relative to said hollow tubular member.
