Abstract:
A vehicle for gliding on snow or ice comprising:a footboard having a front end and a rear end; a handlebar; a steering column having a top end connected to said handlebar and extending downwardly therefrom; a front runner fastened to a bottom end of said steering column, said front runner having a guiding projection formed in a center of an underside thereof, said front runner having a pair of steering projections formed respectively on opposite sides of said guiding projection on said underside of said front runner, said pair of steering projections having respective planar surfaces spacing said pair of steering projections from said guiding projection, said pair of steering projections extending downwardly from said planar surfaces for a distance less than a distance that said guiding projection extends downwardly from said planar surfaces, said front runner having a braking tip extending upwardly and outwardly from each of said pair of steering projections, said guiding projection and the respective planar surface and the respective steering projection defining a snow guiding recess; a rear runner fastened to an underside of said rear end of said footboard, said rear runner having a guiding projection formed in a center of an underside thereof, said rear runner having a pair of steering projections formed respectively on opposite sides of said guiding projections on said underside of said rear runner, said pair of steering projections having respective planar surfaces spacing said pair of steering projections from said guiding projection on said rear runner, said pair of steering projections of said rear runner extending downwardly from said planar surfaces for a distance less than a distance that said guiding projection of said rear runner extends downwardly from said planar surfaces, said rear runner having a braking tip extending upwardly and outwardly from each of said pair of steering projections, said guiding projection and the respective planar surface and the respective steering projection defining a snow guiding recess on said rear runner, at least one of said planar surfaces of said rear runner having a through hole formed therein; and a braking mechanism fastened to said rear end of said footboard, said braking mechanism having a trigger plate fastened at one end to said rear end of said footboard, said braking mechanism having a guide tube fastened to said rear end of said footboard, said braking mechanism having a link rod held by said guide tube, said link rod having a stop piece affixed to a top end thereof, said stop piece being in contact with an underside of said trigger plate, said braking mechanism having a recovery spring fitted over said top end of said link rod such that one end of said recovery spring exerts a force upon said stop piece and such that an opposite end of said recovery spring exerts a force against a top end of said guide tube, said braking mechanism having a brake shoe fastened to a bottom end of said link rod and extended through said through hole, said brake shoe being movable downwardly when an external pressure is directed downwardly onto said trigger plate.
