Abstract
Abstract A spring deck and insulator for furniture consisting of a planar sheet having a continuous series of closely spaced parallel cross wires connected at their ends to flexible side strands and a series of flexible straps extending parallel to and spaced intermediate the side strands, each strap being secured to each of the cross wires at its point of intersection therewith, the sheet being adapted to be inserted with or without edge connections between a spring deck and padding layers of upholstered furniture for use as an insulator pad, or to be used as a spring deck by securing it in a rigid furniture frame by resilient fasteners extending from each of the side strands and from each end of each of the straps, to the frame.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
44 words
A device adapted to be used either as a spring deck or as an insulator pad, comprising a generally planar sheet inelastic in its own plane but possessing substantial resilient resistance to flexure transversely of its plane about any line thereof in any direction.
Claim 2
Independent Claim
44 words
A device adapted to be used either as a spring deck or as an insulator pad, comprising a generally planar sheet inelastic in its own plane but possessing substantial resilient resistance to flexure transversely of its plane about any line thereof in any direction.
Claim 3
Dependent Claim
65 words
A device as recited in claim 1 intended specifically for use as a spring deck, in which is additionally included a series of elongated, longitudinally extensible connectors connected to said sheet at spaced intervals around any desired portions of the periphery thereof and extending outwardly therefrom, said connectors being adapted to be resiliently extended and connected at their outer ends to a rigid furniture frame.
Claim 4
Dependent Claim
79 words
A device as recited in claim 1 wherein said sheet comprises: a. a pair of side strands disposed in generally parallel relation, b. a continuous series of resilient cross wires extending in parallel relation between and secured at their ends to said side strands, and c. resilient straps extending parallel to and intermediate said side strands, and intersecting said cross wires, each of said straps being attached to each of said cross wires at its point of intersection therewith.
Claim 5
Dependent Claim
69 words
A device as recited in claim 3 intended specifically for use as a spring deck, with the addition of a series of elongated, longitudinally extensible connectors connectable to said side strands in spaced relation therealong, and to each end of each of said straps, and extending outwardly from said sheet, said connectors being adapted to be resiliently extended and connected at their oUter ends to a rigid furniture frame.
Claim 6
Dependent Claim
35 words
A device as recited in claim 4, wherein said side strands are also resilient, whereby longitudinal stresses on a plurality of said cross wires are transmitted by said side strands to each of said connectors.
Claim 7
Dependent Claim
58 words
A device as recited in claim 5 wherein each of said side strands includes a resilient wire having an eye formed at each end thereof, and with the addition of connectors connectable to each end of each of said side strands and adapted to be resiliently extended for connection at their outer ends to said rigid furniture frame.
Claim 8
Dependent Claim
48 words
A device as recited in claim 3 wherein each of said side strands constitutes a spring wire core having a sheath of soft, indentable material applied thereto, each of said cross wires being twisted tightly about the sheath of each of said side strands and then about itself.
Claim 9
Dependent Claim
36 words
A device as recited in claim 3 wherein each of said cross wires is attached to each of said straps by means permitting a degree of relative pivotal movement therebetween, in the plane of said sheet.
Claim 10
Dependent Claim
59 words
A device as recited in claim 3 wherein a narrow longitudinal band of each said straps, intermediate the transverse edges thereof and transversely spanning each cross wire intersecting said strap, is offset transversely from the plane of said strap to form a loop in conjunction with the non-offset portion of said strap, said cross wire extending through said loop.
Claim 11
Dependent Claim
27 words
A device as recited in claim 9 wherein said loop is elastically contracted by the resilience of said strap, whereby said wire is gripped in said loop.
