Central binding for holding boot on ski - having two vertical discs on plate of binding and engaging in transversal groove in boot's sole

摘要

The boot (3) is fixed on the ski (2) by two vertical discs (6), mounted transversely on axles (7) in the front plate (5) of the central binding. When the boot is being put in the binding the upper part of the discs' lateral surfaces engages with the lateral surface (8'') of a transversal groove (8) in the boot's sole. When the boot is in place the discs' horizontal upper surfaces rest against the horizontal base (8') of the groove. The discs are double trapeziums and the sides of the groove are at the same angle as their lateral surfaces. USE - For fixing a boot on the central binding of a ski.
