Abstract
Abstract A bed includes a support structure having longitudinally extending bearing beams on which a spring member rests. The spring member includes a plurality of side-by-side modules, each having upper and lower resilient, flexible strips held apart by a plurality of spacers. The spacers are offset from the bearing members so that the upper strip of each module hold the modules together to allow limited independent movement. A pad and a removable fabric cover is provided.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
164 words
A bed or the like including a support structure for resiliently supporting a pad or the like on which a person can sit or lie, said support structure comprising first and second substantially parallel, elongated, spaced-apart bearing members; a plurality of substantially identical elongated modules lying side-by-side on and generally perpendicular to said bearing members, each of said modules including first and second elongated, resilient strips extending substantially the entire length of said module, and a plurality of spacers positioned between said first and second strips to maintain said strips in generally parallel, spaced relationship with respect to each other, with said first strip above said second strip, said spacers being offset from said bearing members; fabric means for loosely holding said modules together in generally parallel relationship while allowing substantially independent limited relative movement, said fabric means including pockets for receiving the ends of said strips, tubular portions for receiving said spacers and a sheet-like portion extending between said strips of said modules.
Claim 2
Dependent Claim
164 words
A bed or the like including a support structure for resiliently supporting a pad or the like on which a person can sit or lie, said support structure comprising first and second substantially parallel, elongated, spaced-apart bearing members; a plurality of substantially identical elongated modules lying side-by-side on and generally perpendicular to said bearing members, each of said modules including first and second elongated, resilient strips extending substantially the entire length of said module, and a plurality of spacers positioned between said first and second strips to maintain said strips in generally parallel, spaced relationship with respect to each other, with said first strip above said second strip, said spacers being offset from said bearing members; fabric means for loosely holding said modules together in generally parallel relationship while allowing substantially independent limited relative movement, said fabric means including pockets for receiving the ends of said strips, tubular portions for receiving said spacers and a sheet-like portion extending between said strips of said modules.
Claim 3
Dependent Claim
100 words
A structure according to claim 1 which includes a plurality of horizontally disposed, parallel bearing members of substantially equal length, the length of said members defining the length of a bed; at least ten modules each including first and second flexible strips each having a width of between about 6 and about 15 cm and a plurality of spacers between said strips, the number of spacers in each module being one greater than the number of bearing members, each spacer having a length substantially equal to the width of its associated strips, said strips being removably positioned in said pockets.
Claim 4
Dependent Claim
52 words
A structure according to claim 2 and further including a soft pad of breathable material lying on said modules, said pad having a thickness of between about 5 and 7 cm, and a removable fabric cover enclosing said pad, said modules and said fabric means for holding said modules and pad together.
Claim 5
Dependent Claim
16 words
A structure according to claim 3 wherein said fabric cover is reinforced along its lateral edges.
Claim 6
Dependent Claim
71 words
A structure according to claim 3 and further including a second support structure having bearing members, a second plurality of modules and fabric means for holding said modules together, said second support structure being adjacent the first said support structure with the upper surfaces thereof generally coplanar, and wherein said pad covers both of said support structures and said removable fabric cover encloses said pad and both of said support structures.
Claim 7
Dependent Claim
22 words
A structure according to claim 2 wherein each of said strips has a width of between about 7.5 and about 9 cm.
Claim 8
Dependent Claim
22 words
A structure according to claim 2 wherein each of said spacers has a length of between about 8 and about 10 cm.
Claim 9
Dependent Claim
18 words
A structure according to claim 2 wherein each of said spacers is made from a substantially incompressible material.
Claim 10
Dependent Claim
28 words
A structure according to claim 2 wherein each of said spacers has a generally circular cross section and a diameter of between about 4 and about 6 cm.
Claim 11
Dependent Claim
22 words
A structure according to claim 2 wherein said sheet-like portion of said fabric means is formed with two layers between said strips.
Claim 12
Dependent Claim
16 words
A structure according to claim 2 including two bearing members and three spacers in each module.
Claim 13
Dependent Claim
28 words
A structure according to claim 2 and including means insertable between said bearing members and selected ones of said modules to vary the surface configuration of said bed.
