Claim One:
1. A stand-on land vehicle made capable of simulating snow-skiing for purposes of dry-land practice, training and instruction relating to recreational, competitive and professional snow-skiing, comprising: a pair of elongate platforms, designated left hand and right hand, held parallel and spaced apart, side-by-side, each providing a substantially flat topside region including an upwardly-facing anti-skid surface for user footing; a dual-mount axle assembly located under rear regions of said platforms and extending laterally to opposite ends configured as wheel axle portions; a pair of rear wheels installed on the wheel axle portions; said dual-mount axle assembly including a pair of angled-pivot swivel tilt-steer rear truck-mounts each having an upper end attached centrally underside a rear region of a corresponding one of said platforms and a lower end adjacent to a corresponding one of said wheels, thus supporting a rear portion of said vehicle at two rear support locations at corner angles between said axle and central axes of said platforms, said angled-pivot swivel tilt-steer rear truck-mounts being oriented to be angled such that (a) whenever the user holds said platforms level and thus untilted laterally, a neutral steering condition is maintained for linear travel, the two corner angles being held rectangular and thus holding said platforms parallel and unskewed, and holding said axle assembly and thus said rear wheels aimed at a zero azimuth angle for linear travel; (b) the user initiates a right hand turn by radially tilting said platforms down at the right, forcing the mounts to re-aim said axle assembly and thus said rear wheels to a negative azimuth angle, thus skewing the right hand platform forward, and (c) conversely, the user initiates a left hand turn by radially tilting said platforms down at the left, forcing the mounts to re-aim said axle assembly and thus said rear wheels to a positive azimuth angle, thus skewing the left hand platform forward, thus forming a primary parallelogram; a primary front spacer, extending horizontally between front center locations of said platforms, is (1) dimensioned in length to match the two rear support locations and thus co-operate therewith to hold said platforms always parallel under all steering conditions, (2) end-fastened to said platforms in a swivel-hinge manner that allows lateral platform tilting by the user, and (b) fastened to at least one front mount with a swivel mechanism angled in mirror image of said rear mounts, made and arranged to aim at least one front wheel to zero azimuth angle for the neutral steering condition, to a positive azimuth angle for a right hand turn and to a negative azimuth angle for a left hand turn; a front wheel structure comprising at least one front wheel supporting a front portion of said vehicle via at least one angled-pivot tilt-steer swivel front mount oriented to be angled in mirror image of said rear mounts, thus aiming said front wheel structure to a positive azimuth angle for a right hand turn and to a negative azimuth angle for a left hand turn.
