A vehicle comprising a support surface, a plurality of carriers on which said support surface is mounted, a castor like structure including a castoring axis and a castor element freely pivotable about said castoring axis for at least one of said carriers, steering pivot means for enabling tilting of said castoring axis relative to said support surface and steering means operable for tilting said castoring axis of said castor like structure about said steering pivot means to steer the vehicle.
A vehicle comprising a framework, two wheels supporting a rear of said framework, a steerable castored wheel supporting a front of said framework and including a castoring axis and a castor wheel freely pivotable about said castoring axis, a seat member mounted towards the rear of said framework, a foot support crossbar mounted towards the front of said framework, steering pivot means for enabling tilting of said castoring axis relative to said seat member and steering means operable by a person seated in said seat for tilting said castoring axis of said steerable castor wheel about said steering pivot means to thereby steer the vehicle.
A vehicle comprising an "L" shaped framework including a base part for carrying luggage or other articles and an upright rear part, two fixed wheels supporting the rear of said base part where it is connected said upright part, a castored wheel supporting the front of said base part and including a castoring axis and a castor wheel freely pivotable about said castoring axis, steering pivot means for enabling tilting of said castoring axis relative to said base part and steering means operable for tilting said castoring axis of said castored wheel about said steering pivot means to steer the vehicle.
A vehicle comprising a substantially "U" shaped frame including two horizontally extending parts spaced apart vertically and joined by a part extending between them, a pair of fixed wheels carrying one end of the lower of the said two horizontally extending parts, a castored wheel carrying the other end of said lower horizontally extending part and including a castoring axis and a castor wheel freely pivotable about said castoring axis, steering pivot means for enabling tilting of said castoring axis relative to said frame and steering means operable for tilting said castoring axis of said castored wheel about said steering pivot means to steer the vehicle.
