A modular innerspring and box spring assembly which can be put together by the end use customer from innerspring and box spring modules. An innerspring module consists of a plurality of coil springs joined together by helical wire fasteners in a generally rectangular configuration having dimensions which when assembled with other like modules in side-by-side and end-to-end relationship make up a completed modular innerspring assembly of the size and shape needed to make a twin, twin extra long, full, full extra long, queen and king size mattress. A top boundary wire assembly extends around the top peripheral edge of the completed modular innerspring assembly and a bottom boundary wire assembly extends around the bottom peripheral edge, in each case secured to adjacent coil springs by a double hook clip. A box spring module consists of a frame made up of end and side strips plus intermediate slats having a plurality of springs secured thereto and extending upwardly therefrom in a generally rectangular configuration having dimensions which when connected with other like box spring modules in side-by-side and end-to-end relationship make up a completed modular box spring assembly of whatever size and shape needed to support a twin, twin extra long, full, full extra long, queen and king size mattress. The box spring modules are secured together by L-shaped angle irons on each bolted to those of adjacent modules.
A modular innerspring assembly comprising a plurality of innerspring modules wherein each one of said plurality of innerspring modules is initially made as a separate and independent structure, each one of said innerspring modules in said plurality thereof comprising a plurality of springs in side-by-side relationship each terminating at one end in a first spring end piece and at the opposite end in a second spring end piece, a peripheral module boundary around each one of the said innerspring modules, said plurality of springs including a peripheral boundary plurality of springs in side-by-side relationship located in and extending around said peripheral module boundary of each one of said innerspring modules, first connecting means to connect adjacent ones of said first spring end pieces of adjacent ones of said springs to each other, second connecting means to connect adjacent ones of said second spring end pieces of adjacent ones of said springs to each other, said peripheral module boundary of each one of said innerspring modules includes a first laterally extending side, a first longitudinally extending side extending from one end of said first laterally extending side normal thereto and terminating at an opposite end, a second laterally extending side extending from said opposite end of said first longitudinally extending side normal thereto in the same direction as said first laterally extending side and terminating at an opposite end a second longitudinally extending side extending from said opposite end of said second laterally extending side normal thereto to said other end of said first laterally extending side, a first one of said innerspring modules being placed with said first longitudinally extending side adjacent to a second longitudinally extending side of a second one of said innerspring modules, including said second one of said innerspring modules having said second longitudinally extending side, a first boundary wire assembly extending completely around one peripheral edge of said modular innerspring assembly at the level of said first spring end pieces of said springs, a second boundary wire assembly extending completely around the other peripheral edge of said modular innerspring assembly at the level of said second spring end pieces of said springs, third connecting means to connect said first boundary wire assembly to adjacent ones of said first spring end pieces of said springs and fourth connecting means to connect said second boundary wire assembly to adjacent ones of said second spring end pieces of said springs, wherein each spring in each peripheral boundary plurality of springs around the periphery of said innerspring modules is the same as each other around all sides of such periphery, including their respective first and second end pieces, whereby any side of any one of said innerspring modules as desired may be placed interchangeably adjacent said first and second boundary wire assemblies and connected thereto by said third and fourth connecting means respectively.
A modular box spring assembly comprising a plurality of box spring modules wherein each one of said plurality of box spring modules is initially made as a separate and independent structure, each one of said box spring modules in said plurality thereof comprising a frame member having an upwardly facing surface lying in a first plane, a plurality of springs extending upwardly from said upwardly facing surface of said frame member and terminating in a plane which is substantially parallel to said first plane, said frame member having a first laterally extending end wall, a first longitudinally extending side wall extending from one end of said first laterally extending end wall normal thereto and terminating at an opposite end, a second laterally extending end wall extending from said opposite end of said first longitudinally extending side wall normal thereto in the same direction as said first laterally extending end wall and terminating at an opposite end, a second longitudinally extending side wall extending from said opposite end of said second laterally extending end wall normal thereto to the other end of said first laterally extending end wall, a first one of said box spring modules being placed with said first longitudinally extending side wall adjacent to a second longitudinally extending side wall of a second one of said box spring modules, including said second one of said box spring modules having said second longitudinally extending side walls, and adjacent wall connecting means to connect and hold adjacent walls of said box spring modules together, said adjacent wall connecting means including a first upwardly extending member secured to a side wall of a said first one of said box spring modules, a second upwardly extending member secured to a side wall of a second one of said box spring modules adjacent to and in facing relationship with said first upwardly extending member, and releasable securing means to releasably secure said first and second upwardly extending members together.
A modular box spring assembly comprising a plurality of box spring modules wherein each one of said plurality of box spring modules is initially made as a separate and independent structure, each one of said box spring modules in said plurality thereof comprising a frame member having an upwardly facing surface lying in a first plane, a plurality of springs extending upwardly from said upwardly facing surface of said frame member and terminating in a plane which is substantially parallel to said first plane, said frame member having a first laterally extending end wall, a first longitudinally extending side wall extending from one end of said first laterally extending end wall normal thereto and terminating at an opposite end, a second laterally extending end wall extending from said opposite end of said first longitudinally extending side wall normal thereto in the same direction as said first laterally extending end wall and terminating at an opposite end, a second longitudinally extending side wall extending from said opposite end of said second laterally extending end wall normal thereto to the other end of said first laterally extending end wall, a first one of said box spring modules being placed with said first longitudinally extending side wall adjacent to a second longitudinally extending side wall of a second one of said box spring modules, including said second one of said box spring modules having said second longitudinally extending side walls, and adjacent wall connecting means to connect and hold adjacent walls of said box spring modules together, wherein said adjacent wall connecting means comprises a first elongated L-shaped member having a vertically extending leg and a horizontally extending leg and a second elongated L-shaped member having a vertically extending leg and a horizontally extending leg, said horizontally extending leg of said first L-shaped member being secured to said first longitudinally extending side wall of said first one of said box spring modules, said horizontally extending leg of said second L-shaped member being secured to said second longitudinally extending side wall of said second one of said box spring modules at a location facing said first L-shaped member, said vertically extending legs of said first and second L-shaped members being in abutting relationship with each other, and releasable securing means to releasably secure said L-shaped members together.
