Self-releasing ski-binding

Claim 1

The combination comprising a ski, a ski boot, and a binding for connecting said boot to said ski, said binding comprising a. a hollow cylindrical member in the sole of said boot, the opposite ends thereof being substantially coterminous with opposite edges of the sole, b. a piston slidable in said cylindrical member, c. stop means preventing said piston from sliding out one end of said cylindrical member, d. a pin having a frusto-conical surface normally extending from said one end of said cylindrical member, e. means adjustably mounting said pin on said piston such that the axial distance between said frusto-conical surface on said pin and said piston may be varied, f. a plug removably secured in the end of said cylinder member opposite said one end, said plug having a frusto-conical surface extending radially from said opposite end of said cylindrical member, g. a plurality of conical spring washers arranged within said cylindrical member and extending between said plug and said piston biasing said piston towards said stop means, and h. fitting means arranged on said ski including a pair of spaced conical recesses therein for receiving said conical surfaces of said pin and plug, i. whereby the axial distance between said frusto-conical surfaces of said pin and plug may be changed by adjusting said pin mounting means and the bias pressure applied to said piston may be changed by removing said plug and rearranging said spring washers relative to each other.
