Abstract
The article disclosed, with method for its manufacture, is a pocketed-spring construction made by joining juxtaposed subassemblies or modules formed by the interconnection of two rows of pocketed springs at intervals of two springs or more according to the resistance to compression desired. Various module joinder techniques are shown and described.
Claims16
An innerspring construction comprising:
- a continuous double row of pocketed springs comprising two connected strings of pocketed springs wherein each string includes a plurality of compartments defined between layers of a fabric strip by spaced transverse seams which also define a connecting web of fabric between successive compartments;
- each of said compartments having therein a spring which is axially transverse to said strip and axially parallel to and coextensive with the other springs of said double row;
- said two strings being joined together at intervals therealong;
- said double row of springs having therein a connected series of modules of equal numbers of springs defined by the regular occurrence therealong of two four-spring clusters centered upon successive interstring connections having a two-spring interval between said successive connections;
- the two strings of said modules having a plurality of interstring connections of their connecting webs at regular intervals of a plurality of springs between said successive interstring connections;
- said modules being separable from said connected series by the severance of one connecting web between said two four-spring clusters at each occurrence thereof along said connected series, alternating between the webs of the two strings at successive such occurrences;
- said construction being formed by the folding of consecutive modules upon each other in opposite directions about the non-severed web between modules as hinges;
- successive juxtaposed modules being connected together remotely from said hinges, with the corresponding ends of said springs in common planes, and the ends of the connected modules aligned along opposite edges of the construction.

A modular subassembly of pocketed springs for mattress constructions comprising a double row of pocketed springs of finite length;
- said double row of pocketed springs comprising two connected strings of pocketed springs wherein each string includes a plurality of compartments defined between layers of a fabric strip by spaced transverse seams which also define a connecting web of fabric between successive compartments;
- each of said compartments having therein a spring which is axially transverse to said strip and axially parallel to and coextensive with the other springs of said double row;
- said two strings being joined together by interstring connections of the webs of the two strings between the two terminal springs of each string and at regular intervals of at least three springs therebetween.
A method of fabricating a pocketed spring construction from a continuous two-row strip of pocketed springs comprising two strings of said springs joined together side by side, wherein each string includes a plurality of compartments defined between layers of a fabric strip by spaced transverse seams which also define a connecting web of fabric between successive compartments;
- each of said compartments having therein a spring which is axially transverse to said strip and axially parallel to and coextensive with the other springs of said double row;
- said two strings being joined together by regular periodic interstring connections of the webs of the two strings at consecutive intervals of two springs therealong;
- severing the connecting webs of each string between said consecutive interstring web connections, alternating between strings at successive periodic interstring connections along said double row of springs to form connected modules of equal numbers of springs;
- folding consecutive said modules in opposite directions about the residual connecting web of the string opposite a severed web, as a hinge for folding adjacent ones of said modules in spring-to-spring contact along said modules;
- and
- connecting adjacent modules together remotely from said hinges to secure said modules together in assembled relation with the corresponding ends of their springs in common planes.
