Abstract
A connector system for mechanically connecting two structural elements to each other, consisting of a connector element and mating grooves in each structural element. The connector element is comprised of a base plate having a split-tongue element at each side or end of said base plate. Each joined element has a mating groove formed into its connector-receiving surface. The mating groove is designed to allow fabrication via four sequential circular saw cuts, without loss of saleable decorative surface, and at a rate consistent with economical commercial production of vinyl, laminate, or hardwood flooring. The connector element is readily extruded in a variety of polymers, including PVC. The connector and mating grooves interact so as to generate a force component acting to forcibly draw the connector into the mating grooves. The connector system operation is relatively insensitive to geometric deviations associated with normal manufacturing methods.
