Abstract
A ski sled with adjustable boot blocks and a rider-operated weight-transfer device for rider-controlled steering. The boot blocks are provided with fixed and/or variable angle adjustment devices for changing the angle of the ski bottoms with respect to the snow surface, and the toe-in angle of the skis with respect to each other. Further, the boot blocks are provided with lengthwise adjustment mechanisms so that the boot blocks may be attached to any standard ski binding used on any ski without modification or any special attachments to the bindings or the skis.
Claims20
A ski sled comprising:
- two skis arranged side-by-side with inward edges of the skis being angled downwardly at least while the sled is turning;
- a seat supported by right and left legs, the legs being rotatably attached at respective pivot points at a rear end of right and left chair rails, rotation of the seat forward and backward enabling a transfer of a partial weight of a rider from tip to tail of the skis;
- adjustable blocks fitting into ski bindings on the skis, the blocks having angle adjustment devices mounted thereon for changing lateral pitches of the two skis, the chair rails being attached to the angle adjustment devices and the angle adjustment devices being attached to the blocks forward of the pivot points;
- and
- a weight transfer device operable by a rider for transferring the partial weight of the rider forward and backward and from one of the two skis to the other, thus enabling the ski sled to turn.

- and
- a weight transfer device operable by a rider for transferring a partial weight of the rider forward and backward and from one of the two skis to the other, thus enabling the ski sled to turn, the weight transfer device including:
- chair rail extensions extending forwardly from the chair rails;
- foot pedals rotatably attached to the chair rail extensions for actuating cables connected to the angle adjustment devices so that when the foot pedal on one side of the sled is pushed, the block on the same side of the sled is articulated,
- the foot pedals enabling a transfer of a partial weight of a rider from tip to tail of the skis,
- wherein an axis of rotation of each of the foot pedals is substantially vertical.
