Claims
- 1. A snowshoe, comprising:
- a snowshoe frame having front and back ends,
- a membrane covering at least a part of said frame so as to form with the frame a snow-engaging snowshoe body,
- a front claw including terrain gripping means extending generally downwardly,
- boot securing means for securing the front claw of the snowshoe to a user's shoe or boot such that a front portion of the user's foot is positioned over the front claw and is generally fixed relative to the front claw,
- resilient strap means secured to the snowshoe frame and to the front claw for connecting the front claw to the snowshoe frame while permitting pivoting motion of the front claw about a horizontal axis relative to the frame when the user's foot is tilted forward with the snowshoe attached, said resilient strap means comprising at least one resilient strap and including preloading means for biasing the front claw angularly relative to the snowshoe body, about a horizontal tilt axis, such that the front claw is biased toward an angularly offset unloaded position, obliquely angled relative to the snowshoe body, at which the rear of the snowshoe frame tilts downwardly relative to the front claw and to the user's foot such that the preloading means urges the back end of the snowshoe frame to pivot down and away from the user's shoe or boot.
- 2. A snowshoe according to claim 1, wherein said angularly offset position of the front claw is at an angle of about 10.degree. to 45.degree. relative to the snowshoe body.
- 3. A snowshoe according to claim 1, wherein the means for preloading comprises said resilient strap means including a pair of front and rear resilient straps, each extending generally laterally across the snowshoe and secured to the snowshoe frame to left and right of the front claw, the front and rear resilient straps being fixed to the front claw at longitudinally spaced apart locations and positioned such that the front claw is biased toward said angularly offset position.
- 4. A snowshoe according to claim 3, wherein the front resilient strap is secured to the snowshoe frame by passing under the frame and the rear resilient strap is secured to the snowshoe frame by passing over the snowshoe frame, thereby establishing the rear resilient strap at a higher position than the front resilient strap and providing said angularly offset position of the front claw.
- 5. A snowshoe according to claim 3, wherein the front and rear resilient straps are formed of a single, continuous length of strap, wound around the snowshoe frame.
- 6. A snowshoe according to claim 1, further including rear cleat means on the snowshoe, secured to the snowshoe body in position to be below a heel of the user's show or boot, for preventing both forward and rearward sliding of the snowshoe on terrain below the snowshoe when some of the user's weight is against the rear cleat.
