Patent ID: 8746648

Claim:
A large load variable spring support, comprising: a base plate; a plurality of spring modules assembled into a spring module array disposed on said base plate; at least one fixed top bar fixedly connected to said base plate by vertical columns; a plurality of through-holes provided in said fixed top bar; a plurality of stop rods with top and bottom ends, said stop rods being slidably received in said through-holes of said fixed top bar; a floating bar slidably received on said plurality of stop rods at said bottom ends and supported by a plurality of floating bar nuts near said bottom ends of said plurality of stop rods, wherein rotation of said floating bar nuts in a first direction causes advancement of said floating bar nuts along said stop rods in a first vertical direction and rotation of said floating bar nuts in a second direction causes advancement of said floating bar nuts along said stop rods in a second direction and wherein said floating bar supported by said floating bar nuts will advance as said floating bar nuts advance; a plurality of cross beams supported at opposing distal ends by said vertical columns and having cantilever plates at said distal ends, wherein said plurality of cross beams are fixedly connected to said at least one fixed top bar at said cantilever plates; and a plurality of travel stop lock nuts threadably engaged with said stop rods such that said stop lock nuts engage a bottom surface of said fixed top bar to prevent vertical upward movement of said stop rods and maintain said spring modules in a compressed position.
