Abstract
The present invention relates to a ski binding used in telemark skiing. An exemplary system maintains a toe of a ski boot in association with a ski while permitting a heel of the ski boot to elevate to a top surface of the ski. The binding system comprises several complex subsystems, such as a toe mating mechanism, a toe plate system, a base plate system, a heel fastening mechanism, a sliding plate system, and rail system.
Claims10
A telemark ski binding system comprising:
- a toe mating mechanism having a toe bail and a knuckle;
- a toe block mechanism, the toe bail of said toe mating mechanism is pivotably coupled to said toe block mechanism, the knuckle of said toe mating mechanism is pivotably coupled to said toe block mechanism, said toe bail and knuckle pivotal on the same axis;
- a base plate system having a base plate, said base plate adjustably and detachably engageable with said toe block mechanism;
- and
- a rear case, said rear case engageable to couple to said base plate system;
- a rail forming a part of said base plate system, wherein during operation of the telemark ski binding system, said rear case lowers onto the rail;
- a main tube coupled to said rear case;
- wherein the rear case translates along a longitudinal axis of the main tube and is constrained from translating laterally with respect to the main tube;
- and
- wherein the rear case comprises a precision bearing surface that mates with the main tube, the precision bearing surface delimits an interior cylindrical hollow, said hollow in a portion of the rear case and said precision bearing surface slides over the main tube when the rear case translates along the longitudinal axis.
