Abstract
A ski attachment attachable to a wheel defining a nadir section, the ski attachment comprising: an elongated ski defining a longitudinal axis, the ski having a deck and a base, the ski defining longitudinally opposed nose and tail ends; a wheel mount for mounting the wheel to the ski at a location intermediate the nose and tail ends, the wheel mount defining a nadir receiving portion for receiving the nadir section; and a wheel lock for locking the wheel to the wheel mount; wherein the base is configured so that a larger friction is exerted on the ski attachment rearward of the nadir receiving portion than frontward of the nadir receiving portion when the ski attachment is pushed on a surface at an angle relative to the longitudinal axis.

A ski attachment attachable to a wheel, the wheel defining a nadir section, the ski attachment comprising:
- an elongated ski defining a longitudinal axis, the ski having a deck and a base, the ski defining longitudinally opposed nose and tail ends;
- a wheel mount for mounting the wheel to the ski at a location intermediate the nose and tail ends, the wheel mount defining a nadir receiving portion for receiving the nadir section;
- and
- a wheel lock for locking the wheel to the wheel mount;
- wherein the base defines base front and rear portions extending from the nadir receiving portion respectively towards the nose and tail ends, the base rear portion being shorter than the base front portion, the base front and rear portions having respectively front and rear transversal profiles differing from each other with the front and rear transversal profiles configured so that more than half of the tangential cutting torque required to perform rotations of the ski about a rotation axis perpendicular to the base through snow is exerted on the base rear portion.
A ski attachment attachable to a wheel, the wheel defining a nadir section, the ski attachment comprising:
- an elongated ski defining a longitudinal axis, the ski having a deck and a base, the ski defining longitudinally opposed nose and tail ends;
- a wheel mount for mounting the wheel to the ski at a location intermediate the nose and tail ends, the wheel mount defining a nadir receiving portion for receiving the nadir section;
- and
- a wheel lock for locking the wheel to the wheel mount;
- wherein the base defines base front and rear portions extending from the nadir receiving portion respectively towards the nose and tail ends, the base rear portion being shorter than the base front portion, the base front and rear portions having respectively front and rear transversal profiles differing from each other with the front and rear transversal profiles configured so that a larger friction is exerted on the ski attachment rearward of the nadir receiving portion than frontward of the nadir receiving portion when the ski attachment is pushed on a surface at an angle relative to the longitudinal axis.
A ski attachment attachable to a swiveling wheel defining a nadir section, the ski attachment comprising:
- an elongated ski having a deck and a base, the ski defining longitudinally opposed nose and tail ends;
- a wheel mount for mounting the swiveling wheel to the deck at a location intermediate the nose and tail ends, the wheel mount defining a nadir receiving portion for receiving the nadir section;
- and
- a wheel lock for locking the wheel to the wheel mount;
- wherein the base defines base front and rear portions extending from the nadir receiving portion respectively towards the nose and tail ends, the base rear portion being shorter than the base front portion, the base front and rear portions having respectively front and rear transversal profiles differing from each other with the front and rear transversal profiles configured so that the ski attachment is self-orienting, such that, with the ski attachment operatively mounted to the swiveling wheel, the swiveling wheel is automatically oriented so that the nose end faces forwardly when the ski attachment is advanced.
