Abstract
A maneuverable ski machine is provided having a seat frame supported by spaced skis and individual manual controls are provided for swinging the skis about vertical axes into "snow plow" stopping or turning positions. Banking devices automatically bank the skis in proportion to the amount of swinging movement. The controls are also effective to swing and bank the skis into "parallel" turning positions and to properly laterally locate the skier's center of gravity during execution of parallel turns.
Claims8
A ski machine comprising:
- a frame including a seat;
- a pair of spaced skis;
- means supporting said frame on said skis;
- individual manually controlled means for swinging respective ones of said skis from parallel running positions to forwardly converging positions;
- means responsive to said swinging of said skis toward said forwardly converging positions for banking said skis;
- and
- means responsive to movement of a first one only of said skis to said converging position to cause the other of said skis to swing to a position at least substantially parallel to said first ski.

A ski machine comprising:
- a frame including a seat;
- a pair of spaced skis;
- means supporting said frame on said skis;
- individual manually controlled means for swinging respective ones of said skis from parallel running positions to forwardly converging positions;
- and
- means responsive to said swinging of said skis toward said forwardly converging positions for banking said skis;
- said frame supporting means comprising;
- first means pivotally connecting said skis to said frame for swinging movement about first vertical axes;
- a pair of support devices;
- means mounting said support devices on said frame for lateral movement relative to said frame;
- second means pivotally connecting said skis to respective ones of said support devices for swinging movement about second vertical axes spaced along the length of said skis from said first axes;
- and
- means operable by said manually controlled means for independently moving said support devices relative to said frame whereby to swing said skis to different forwardly converging positions.

A ski machine comprising:
- a frame including a seat;
- a pair of spaced skis;
- means supporting said frame on said skis;
- brake pedals for respective ones of said skis;
- means pivotally supporting each of said pedals at the rear thereof on a respective one of said skis for movement about a horizontal axis;
- and
- a braking element at the forward end of each of said pedals;
- said pedals being operable by gravity to engage said braking elements with a ski supporting surface;
- and
- means for enabling a skiers feet to hold said pedals against gravity whereby to maintain said braking elements out of engagement with said ski supporting surface.
