Abstract
A skishoe having a central, downwardly concave arch portion, an upwardly concave toe portion, an upwardly concave heel portion, and a snow gripping blade. The snow gripping blade is pivotable about an axis lying within the camber of the arch portion and extending transversely of the skishoe. A first adjustable blade stop is provided for limiting the angular deflection of the gripper blade from its fully retracted position in the camber. A second adjustable blade stop is provided for limiting the retraction of the blade into the camber, and a spring is provided for resiliently biasing the blade toward the first adjustable blade stop.
Claims7
A skishoe, comprising:
- a body member having an upper face and a lower, snow-contacting face opposed thereto, and having a central arch portion, an upwardly curved toe portion, and an upwardly curved heel portion;
- said arch portion defining a downwardly concave camber;
- snow-engaging brake blade means pivotably mounted for pivoting about a pivot axis which passes through said camber and extends transversely of said body member;
- resilient biasing means for pivotally biasing said brake means about said pivot axis to extend an outer portion of said brake blade means remote from said pivot axis outwardly from said camber;
- adjustable extension limit stop means for adjustably limiting the extension of said outer portion of said brake blade means from said camber;
- and
- adjustable retraction limit stop means for adjustable limiting the retraction of said outer portion of said brake blade means into said camber;
- said retraction limit stop means being adjustable by a user standing on said skishoe and a skishoe paired therewith to vary the maximum retraction of said outer portion of said brake blade means into said camber.
