Toe iron for safety ski bindings

Claim 1

A toe iron for safety ski bindings, which toe iron comprises a four-bar linkage and a baseplate fixed to the ski, said baseplate having a vertical pivot pin fixedly mounted on the rearward central portion thereof, a carrier pivotally connected to the baseplate about said pivot pin, and said four-bar linkage including a pair of laterally spaced two-armed levers and a transversely extending soleholder member acting as a coupling link between said levers, each of said levers being pivotally Mounted to said carrier about respective pivot axes positioned forwardly of said pivot pin, each of said levers being further pivotally connected at its rearward end to said coupling link about respective coupling link pivot axes, and wherein the distance between the pivot axes of the levers exceeds the distance between the coupling link pivot axes, said toe iron further comprising a stop rigidly connected to said baseplate at a forward central portion thereof forwardly of said lever pivot axes, the forward end of each of said levers forming a locking member normally engaging said stop, said locking members locking the carrier against a pivotal movement to respective sides when the soleholder member is in its normal position, and the forward end of said carrier having a guide member rigidly connected thereto, a longitudinally adjustable bearing bracket carried in said guide member, the rearward end of each of said levers having a nose portion extending inwardly toward the longitudinal center line of said toe iron, a compression spring positioned with the forward end of said spring abutting against said bearing bracket and the rearward end of said spring abutting against said nose portions, and said spring opposing a pivotal movement of the four-bar linkage from its normal position.
