Abstract
Abstract A leg support specifically designed for application to the back of the lower portion of a skier''s leg. The leg support is fabricated of a rigid substance and is designed to be secured by a strap. The leg support overlaps the upper portion of the back of the ski boot whereby the stiffness of the back of the ski boot is transferred upwardly onto the skier''s calf, adding strength to the skier''s leg during ''''availment.'''' The term ''''availment'''' refers to the technique of leaning back on the skis for acceleration.

Claim 1
Independent Claim
199 words
A leg support for adding strength to the back of a skier''s leg when leaning back on the skis, comprising; an elongated rigid body member curved to fit the lower portion of the leg having a bulbous upper portion adapted to contact and terminate at approximately the bottom of the calf portion of the leg and a narrow lower portion adapted to contact the exterior of the skier''s boot adjacent the ankle area, and strap means secured to the rigid body member on the narrow lower portion but spaced from the bottom end thereof whereby the body member serves as a first class lever, said strap means adapted to be secured around the boOt upper at a substantially vertical portion of the boot, for securing the leg support in a position whereat it overlies the skier''s lower leg and the boot, extending the stiffness of the back of the boot and the leg support upwardly on the wearer''s leg limiting the rearward movement of the leg relative to the boot whereby the strap means serves as a fulcrum tending to pivot the foot about the ankle and to lift the front of the ski when the skier leans backwards.

A leg support for adding strength to the back of a skier''s leg when leaning back on the skis, comprising; an elongated rigid body member curved to fit the lower portion of the leg having a bulbous upper portion adapted to contact and terminate at approximately the bottom of the calf portion of the leg and a narrow lower portion adapted to contact the exterior of the skier''s boot adjacent the ankle area, and strap means secured to the rigid body member on the narrow lower portion but spaced from the bottom end thereof whereby the body member serves as a first class lever, said strap means adapted to be secured around the boOt upper at a substantially vertical portion of the boot, for securing the leg support in a position whereat it overlies the skier''s lower leg and the boot, extending the stiffness of the back of the boot and the leg support upwardly on the wearer''s leg limiting the rearward movement of the leg relative to the boot whereby the strap means serves as a fulcrum tending to pivot the foot about the ankle and to lift the front of the ski when the skier leans backwards.
Claim 3
Dependent Claim
41 words
A leg support as in claim 1 including inwardly extending means which comprise a pair of integral protrusions having substantially flat lower portions adapted to abut the upper edge of the boot and limit the downward movement of the leg support.
Claim 4
Dependent Claim
159 words
A leg support for use by a skier and adapted to be applied to the back of the lower leg and overlapping the ski boot comprising; an elongated main body portion having a relatively narrow first end and a generally bulbous second end, said main body portion being generally concave in configuration along its longitudinal axis when viewed from the side adapted to contact the back of the skier''s leg and being outwardly flared on the bulbous second end, an outwardly extending ridge paralleling the longitudinal axis and spaced from the ends of the body portion, means associated with the ridge adapted to receive a securing strap, a securing strap extending laterally on both sides of strap receiving means and positioned to overly the upper portion of the skier''s boot, and an inwardly protruding means on the inner surface of the body portion adapted to contact the upper edge of the ski boot and prevent relative downward movement thereof.
