ABSTRACT:
A three-piece cleat assembly for use on athletic shoes which have, embedded in their soles, an interlocking receptacle, such as that used in the Q-LOK R system. Molded of plastic, the cleat assembly includes a connector, a traction-enhancing member and a T-shaped member. The latter includes a stem from one end of which arms project outwardly. Distal from these arms, the stem is bifurcated into two branches. During assembly, the stem of the T-shaped member is inserted through a center hole in the traction-enhancing member; and the branches are squeeze-fitted into et square bore within the connector. Upon being released, the branches spring apart, pressing against the connector. Simultaneously, the arms nest snugly within troughs formed in the base of the traction-enhancing member; and a barb on the tip of each branch is caught on a shoulder rimming the square bore. To affix the cleat assembly, one simply inserts a trifurcated element on one end of the connector into the embedded receptacle and then rotates the connector through about 60 degrees. When rotation is complete, leaf spring-type fingers on the trifurcated element re-extend themselves, fitting into pockets in the receptacle and locking the connector in position. The traction-enhancing member includes arcuate-shaped, tapered ridges arrayed generally concentrically about the center hole. In use, the traction-enhancing member is mounted so that the thickest part of each ridge is closest to the shoe. As the ridges flex, mud picked up by the cleats becomes dislodged.
