A pair of front and rear abutment members are supported in longitudinally spaced position upon the mid-portion of a ski for vertical and lateral shifting relative to the ski and the abutment members include downwardly facing partial spherical seating surfaces abutted against upwardly facing seating surfaces on the ski. Coiled spring structure is enclosed within each abutment member and connected between the latter and the ski for yieldingly biasing the abutment members into tight seated engagement with the upwardly facing seating surfaces carried by the ski. A ski boot is provided and includes extending opposite heel and toe sole portions having upwardly and outwardly opening V-shaped notches formed therein and the ski boot is snugly received between the abutment members with the adjacent portions of the partial spherical surfaces of the abutment members seated in the upwardly and outwardly opening V-shaped notches in the extended toe and heel portions of the ski boot sole. In this manner the ski boot is clamped in position on the ski and yet may be disengaged from the latter as a result of sufficient pressure being exerted on one or both of the abutment members by the boot to cause displacement of either one or both of the abutment members from its seated position.
In combination, a horizontal ski defining a ski boot sole receiving area, a ski boot disposed on said ski in said area, and first and second coacting means on said ski and boot releasably retaining said boot on said ski, said boot including toe and heel portions defining upwardly and outwardly opening oppositely inclined V-shaped notches defining said second means, said first means including a pair of abutment members having adjacent portions defining downwardly facing partial spherical abutment surfaces opposing and seated in said notches, support means supporting said abutment members in predetermined positions on said ski and for limited shifting of each abutment member upwardly away from said ski in all directions within an inverted conical zone thereabove, said support means including shifting resisting means yieldingly resisting shifting of said abutment members from said predetermined positions.
In combination, a ski defining a ski boot sole receiving area, a ski boot disposed on said ski in said area, and first and second co-acting means on said ski and boot releasably retaining said boot on said ski, said boot including toe and heel portions defining upwardly and outwardly opening notches defining said second means, said first means including a pair of abutment members having adjacent portions defining downwardly facing abutment surfaces seated in said notches, support means supporting said abutment members in predetermined positions on said ski and for limited shifting of each abutment member away from the other, said support means including shifting resisting means yieldingly resisting shifting of said abutment members from said predetermined positions, said support means including a pair of base portions supported from said ski each defining a first upwardly facing seating surface and each of said abutment members defining a second downwardly facing seating surface seatingly engaged with the corresponding first seating surface, said shifting resisting means including adjustable spring means yieldingly resisting displacement of said abutment members relative to said base portions.
In combination, a horizontal ski defining a ski boot sole receiving area, a ski boot disposed on said ski in said area, and first and second coacting means on said ski and boot releasably retaining said boot on said ski, said boot including toe and heel portions defining upwardly and outwardly opening notches defining said second means, said first means including a pair of abutment members spaced longitudinally of said ski and having adjacent portions defining downwardly facing abutment surfaces seated in said notches, support means supporting said abutment members in predetermined positions on said ski and for limited upward displacement of each abutment member from said ski in all directions within an inverted conical zone thereabove as well as limited shifting in all horizontal directions relative to said ski, said support means including shifting resisting means yieldingly resisting shifting of said abutment members from said predetermined positions.
