ABSTRACT:
A ski binding of the cross-country type in which a ski boot's heel may be elevated with respect to the ski's top surface while in the act of skiing. The binding includes a toe piece associated with a heel retainer through a spring-biased linkage. A linkage typically includes a pre-loaded compression spring mounted external to a core element. A preferred linkage includes a plurality of rigid link elements defining plurality of intermediate pivot axes between an anchor and the heel retainer. Certain preferred linkage systems permit unfettered boot flexion, but transversely maintain the heel retainer in a zone over the ski to facilitate step-in engagement. Desirably, the core is adjustable along the linkage, to change a spacing between the toe piece and heel retainer independent of spring pre-load. Preferred embodiments of the binding a rear frame adapted to permit step-in engagement of a ski boot. Certain frames may carry a televator. A frame may function as a rear shim to permit adjusting a binding to fit boots of different sizes without necessitating adjustment of the position of a rear shim installed on a ski.
