Safety toe units for ski bindings

摘要

A safety toe unit for a ski binding in which a spring is used to urge together two pairs of complementary abutment surfaces defined between a toe clamp and a base portion to either side of the longitudinal axis of the unit. Sideways release is achieved by angular displacement of the toe clamp about either of the pairs of complementary abutment surfaces against the force of the spring. The present toe unit allows the toe clamp to be vertically adjusted while preserving the alignment between the line of action of the spring force and the toe clamp thus avoiding undesirable tilting moments which could affect the sideways release characteristics. The spring, which may be either in compression or tension, is adjustably located in an extension of the toe clamp between two spring abutments associated respectively with the toe clamp and base portion. Both spring abutments are arranged to move vertically with the toe clamp on adjustment of a vertical adjustment screw. Several embodiments are described.
