Spring base and method of forming same

Claim 1

A spring base comprising a plurality of spaced elongate longitudinally extending first rod-like members, a plurality of springs, one end of each of said springs being constituted as a closed loop of greater lateral extent than the spacing between associated members of said first rod-like members, upper portions of each closed loop being disposed against under surfaces of said associated members of said first rod-like members, a plurality of spaced elongate transversely extending second rod-like members, said closed loop of each of said springs being of greater lateral extent than the spacing between associated members of said second rod-like members, opposite lower portions of each closed loop being disposed against upper surfaces of said associated members of said second roD-like members, said first and second rod-like members defining an intersecting grid-like array with said springs being operatively associated with respective openings in said grid-like array, said respective openings each being defined by a respective pair of said associated members of said first rod-like members and a respective pair of said associated members of said second rod-like members, first portions of said under surfaces of said associated members of said first rod-like members being disposed against second portions of said upper surfaces of said associated members of said second rod-like members, and securing means for connecting each of said first and second portions to one another respectively at mutually intersecting positions for biasing said first rod-like members against said upper portions of each closed loop in one direction and for biasing said second rod-like members against said opposite lower portions of each closed loop in an opposite direction to monolithically wedge and restrain said closed loops of said springs against dislodgement.
