ABSTRACT:
A skate primarily intended for speed skating. The skate is of the clap type wherein the blade is pivotally movable with respect to the boot. A coupling assembly includes top and bottom linkages pivotally attached to one another and is disposed to permit pivotal movement between the blade and the boot. The upper linkage is attached to the boot and the lower linkage is attached to the blade. A biasing arrangement moves the linkages into a closed position. The biasing arrangement includes a spring, a pulley, and a roller. The spring attached at its fore end to the bottom linkage. The cable is attached to the aft end of the spring, is guided around the pulley, and is attached to the top linkage. A significant portion of the biasing arrangement is shielded within the bottom linkage for protection and to provide a compact and effective design. The orientation and features of the biasing arrangement and guide surfaces of the linkages minimizes torsional forces on the coupling assembly, minimizes wear, and increases spring tension forces.
