Abstract
Abstract A two wheeled, electrically powered vehicle having an outer contour resembling a piece of luggage and including a handlebar controlled steering column which is retractable into the luggage shaped vehicle to facilitate the carrying of the vehicle. The steering column is connected to one of the wheels and is movable to facilitate the steering of the vehicle while, at the same time, an electrically powered motor mounted to the steering column provides the motive force for driving the steered wheel to propel the vehicle.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
349 words
A powered vehicle comprising: an integrally formed body frame, resembling a suitcase, bounded by a top wall, a front wall, a rear wall, and side walls; a pair of wheels supporting said frame; a steering column having a lower portion rotatably carried by said frame, said lower portion of said steering column being coupled to one of said wheels to facilitate the steering of said vehicle when said steering column is rotated with respect to said frame; an upper portion of said steering column being longitudinally slidably received in said lower portion and movable between a raised position and a lowered position; means for releasably securing said upper portion to said lower portion when in either said raised or lowered positions, such that said upper portion of said steering column is rotatable with said lower portion when said upper portion is in said raised position and releasably secured with said lower portion, and said upper portion is movable with respect to said lower portion when not secured to said lower portion; handlebar means carried by said upper portion and movable with said upper portion to a front to rear position with respect to said vehicle such that one end of said handlebar means is in close proximity to said top wall of said frame when said upper portion of said steering column is in said lowered position; and the other end of said handlebar means projecting outwardly from said front wall of said vehicle, whereby, when said handlebar means is in said front to rear position, said one end of said handlebar means serving as a means for lifting and carrying said vehicle, the other end of said handlebar means serving to facilitate the manual propelling of said vehicle on at least one of said wheels; said handlebar means are coupled with said steering column by a non-circular arrangement for positioning said handlebar in 90° increments for fail-safe torsional coupling for steering said vehicle in said operative mobile condition and for acurate positioning of said handlebar means with respect to said steering column in said front to rear position.

Claim 3
Dependent Claim
206 words
An electrically powered vehicle comprising: an integrally formed body frame; a plurality of wheels supporting said frame including a front driven wheel; a steering column carried by said frame having an upper and a lower portion; an electric motor carried by said steering column; an angled member having a base and means for mounting an axle on which said driven wheel is rotatably mounted and supported, said base of said member mounting said electric motor; means connecting the mechanical output of said electric motor to said wheel to drive the same; and means fixedly attaching one end of said lower portion of said steering column to said electric motor such that said front driven wheel, said angled member, said electric motor, and said lower portion of said steering column unitedly form one member adapted to facilitate the steering of said electrically driven wheel; bearing means carried by said frame and rotatable with respect to said frame, said bearing means having a splined bore, the opposite end of said lower portion of said steering column having a splined portion slidably received within said splined bore; and shock absorbing spring means carried by said lower portion of said steering column and engaging with a portion of said frame.
