Abstract
A spring loaded locking system for a box spring assembly having a generally rectangular frame, a plurality of spring modules and a grid type wire support deck disposed a predetermined distance above the frame. The locking system provides an interference fit which secures the spring modules to the support deck. Each spring has a pair of outwardly open V-shaped sections integrally formed with the upper portion of the spring. The vertices of the V-shaped sections commonly contact one wire of the support deck. A pair of legs extends from each vertex and straddle the common wire and either cross one of a pair of parallel brace wires of the support deck. The V-shaped sections are biased apart from each other by the shape of the upper portion of the spring module itself. The interaction between the vertices and the common wire, between the legs and the brace wires, and the outward bias of the upper portion of the spring module provides an interference lock fit which secures the support deck to the spring module.
