Abstract A bedspring includes a plurality of spaced parallel longitudinal cross wires and a plurality of spaced parallel transverse cross wires connected to each other at respective cross points and having the ends thereof connected to a frame. The cross wires together form an intersecting grid-like array. Coil springs each have a coil turn at one end thereof which is positioned in a space in the grid-like array of cross wires. Each coil turn is interposed between one pair of transversely extending cross wires and one pair of longitudinally extending cross wires which together form the respective space. The longitudinal extending cross wires include offset portions or indentations which receive or accommodate opposite peripheral portions of a respective coil turn while the latter abuts against the transverse cross wires. The offset portions in the longitudinal cross wires maintain the coil turns in abutment with the transverse cross wires without the application of excessive compressive forces on the coil turns and without the generation of excessive internal stresses in the bedspring after the latter is assembled. A method of forming the bedspring in accordance with the present invention is also described.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
191 words
A bedspring comprising a series of spaced elongate transversely extending members arranged substantially in a common plane; a series of spaced elongate longitudinally extending members disposed on one side of said plane and fixedly connected to said transversely extending members to form an intersecting grid-like array defining a plurality of spaces; at least one of said series of members being provided with indentations recessed in a direction away from the other of said series of members; a frame extending around said grid-like array, the free ends of said elongate members being connected to said frame and being supported by the latter; a plurality of coil springs each having a coil turn at one end thereof positioned coextensively with a space of said grid-like array of members, each end coil turn having dimensions greater than the spacing between adjacent longitudinal members and being interposed between one pair of transversely extending members and one pair of longitudinally extending members to position opposite peripheral portions of each end coil turn within respective indentations, whereby each coil spring is fixed in position in said grid-like array and is prevented from separating from the bedspring members.
Claim 2
Dependent Claim
191 words
A bedspring comprising a series of spaced elongate transversely extending members arranged substantially in a common plane; a series of spaced elongate longitudinally extending members disposed on one side of said plane and fixedly connected to said transversely extending members to form an intersecting grid-like array defining a plurality of spaces; at least one of said series of members being provided with indentations recessed in a direction away from the other of said series of members; a frame extending around said grid-like array, the free ends of said elongate members being connected to said frame and being supported by the latter; a plurality of coil springs each having a coil turn at one end thereof positioned coextensively with a space of said grid-like array of members, each end coil turn having dimensions greater than the spacing between adjacent longitudinal members and being interposed between one pair of transversely extending members and one pair of longitudinally extending members to position opposite peripheral portions of each end coil turn within respective indentations, whereby each coil spring is fixed in position in said grid-like array and is prevented from separating from the bedspring members.
Claim 3
Dependent Claim
36 words
A bedspring as defined in claim 1, wherein said indentations comprises offset portions in said one pair of members substantially parallel to the latter and offset from the longitudinal extent of the latter a predetermined distance.
Claim 4
Dependent Claim
21 words
A bedspring as defined in claim 2, wherein said predetermined distance substantially equals the cross sectional diameter of said coil turn.
Claim 5
Dependent Claim
33 words
A bedspring as defined in claim 2, wherein said predetermined distance is slightly smaller than the cross sectional diameter of said coil turn, whereby said coil turn abuts against said members without clearance.
Claim 6
Dependent Claim
40 words
A bedspring as defined in claim 1, wherein each member in said one pair of members has a length portion coextensive with said coil turn, each indentations comprising an offset portion which includes at least a respective coextensive length portion.
Claim 7
Dependent Claim
24 words
A bedspring as defined in claim 5, wherein each offset portion extends substantially between two adjacent elongAte members of said other pair of members.
Claim 8
Dependent Claim
48 words
A bedspring as defined in claim 1, wherein said frame comprises an open rectangular frame having corner portions, and wherein respective ones of said longitudinally and transversely extending cross members adjacent to said frame meet and overlap adjacent to respective corner portions and are connected to the latter.
