Abstract
Abstract A vehicle having interchangeable and reversible parts with which it can be converted into a number of different types of vehicles. The parts of the vehicle include a frame, having a forked rear, a mounted fork at the front of the frame for rotational movement about a substantially vertical axis, to which is attached a front wheel, a handlebar attached to the fork, a seat attached to the frame, and an auxiliary seat assembly attached to the rear of the frame supported by a pair of rear wheels. The auxiliary seat assembly is reversible and removable.

Total Claims: 7
Claim 1
Independent Claim
254 words
A movable vehicle comprising a frame having a forked rear section, a front steering assembly having a wheel mounted thereon mounted on said frame, means for rotating said wheel mounted on said steering assembly, a seat mounted on said frame, an auxiliary seat assembly fastened to said frame being supported by a pair of wheels mounted on opposed ends of an axle which extends through said seat assembly, and a cross rod on said seat assembly parallel to said axle and being slidably mounted through said forked rear section, said auxiliary seat assembly including opposed lower horizontal tubular portions mounting said axle and cross rod, opposed backwardly curved tubular portions attached to the front ends of said lower horizontal tubular portions, opposed intermediate horizontal tubular portions attached to the top of the opposed curved portions, opposed frontwardly curving portions attached to the backs of the opposed intermediate portions, and opposed upper horizontal portions attached to the top of the frontwardly curved portions, said upper horizontal portions being attached to each other at the front thereof by a first tubular member and said lower horizontal portions being attached to each other at the rear thereof by a second tubular member, and a clamp secured to and projecting from the frame, terminating in a transverse sleeve, said first tubular member being slidably mounted through said sleeve, whereby said seat assembly may be offset laterally relative to said frame by movements of said cross rod and first tubular member relative to said frame and forked rear section.
Claim 2
Dependent Claim
254 words
A movable vehicle comprising a frame having a forked rear section, a front steering assembly having a wheel mounted thereon mounted on said frame, means for rotating said wheel mounted on said steering assembly, a seat mounted on said frame, an auxiliary seat assembly fastened to said frame being supported by a pair of wheels mounted on opposed ends of an axle which extends through said seat assembly, and a cross rod on said seat assembly parallel to said axle and being slidably mounted through said forked rear section, said auxiliary seat assembly including opposed lower horizontal tubular portions mounting said axle and cross rod, opposed backwardly curved tubular portions attached to the front ends of said lower horizontal tubular portions, opposed intermediate horizontal tubular portions attached to the top of the opposed curved portions, opposed frontwardly curving portions attached to the backs of the opposed intermediate portions, and opposed upper horizontal portions attached to the top of the frontwardly curved portions, said upper horizontal portions being attached to each other at the front thereof by a first tubular member and said lower horizontal portions being attached to each other at the rear thereof by a second tubular member, and a clamp secured to and projecting from the frame, terminating in a transverse sleeve, said first tubular member being slidably mounted through said sleeve, whereby said seat assembly may be offset laterally relative to said frame by movements of said cross rod and first tubular member relative to said frame and forked rear section.
Claim 3
Dependent Claim
60 words
In the vehicle of claim 1, said seat assembly on disconnection of said axle, cross rod and clamp, being reversible end to end in a horizontal plane relative to said frame, with said axle extended through said forked rear section and with the said frontwardly curved portions facing rearwardly, and one of said latter curved portions clamped to said frame.
Claim 4
Dependent Claim
17 words
In the vehicle of claim 2, said forked rear section being located outside of said seat assembly.
Claim 5
Dependent Claim
