Abstract
Abstract Disclosed herein is an edge stiffener for mattresses. The stiffener is of single piece construction and includes a pair of oppositely projecting lateral mounting arms which are adapted to be carried by the upper and lower border wires of the mattress and which bend at their inner ends to define a corresponding pair of angularly disposed cantilever spring portions joined in a centrally disposed anchor loop.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
85 words
A single piece edge stiffener for mattresses having means at the extended ends thereof for securing said stiffener to the edge of a mattress, a pair of coplanar cantelever spring portions extending inwardly of said extended ends from each of said securing means and being integrally joined at the inner ends thereof in a substantially semi-circular anchor loop, said anchor loop being open at its inner end and coplanar with said cantelever spring portions and adapted to be disposed about a portion of said mattress.
Claim 2
Dependent Claim
85 words
A single piece edge stiffener for mattresses having means at the extended ends thereof for securing said stiffener to the edge of a mattress, a pair of coplanar cantelever spring portions extending inwardly of said extended ends from each of said securing means and being integrally joined at the inner ends thereof in a substantially semi-circular anchor loop, said anchor loop being open at its inner end and coplanar with said cantelever spring portions and adapted to be disposed about a portion of said mattress.
Claim 3
Dependent Claim
33 words
The combination of claim 1 wherein said securing means comprises a pair of oppositely projecting lateral mounting arms, said spring portions extending from and being angularly disposed with respect to said mounting arms.
Claim 4
Dependent Claim
26 words
The combination of claim 1 including bends in the inwardly extended portions of said spring portions to define substantially parallel extensions terminating in said anchor loop.
Claim 5
Dependent Claim
121 words
A single piece edge stiffener for mattresses of the type having upper, lower and intermediate border wires wherein the intermediate wire is inwardly disposed of the mattress from the upper and lower wires, said stiffener comprising: a pair of oppositely projecting mounting arms at the entended ends thereof, adapted to be carried by the upper and lower border wires of the mattress, respectively; and a corresponding pair of coplanar cantelever spring portions integrally formed with and extending inwardly at corresponding angles from said mounting arms and being integrally joined at the inner ends thereof in a substantially semi-circular anchor loop, said loop being open at its inner end and adapted to be disposed about the intermediate border wire of said mattress.
Claim 6
Dependent Claim
121 words
A single piece edge stiffener for mattresses of the type having upper, lower and intermediate border wires wherein the intermediate wire is inwardly disposed of the mattress from the upper and lower wires, said stiffener comprising: a pair of oppositely projecting mounting arms at the entended ends thereof, adapted to be carried by the upper and lower border wires of the mattress, respectively; and a corresponding pair of coplanar cantelever spring portions integrally formed with and extending inwardly at corresponding angles from said mounting arms and being integrally joined at the inner ends thereof in a substantially semi-circular anchor loop, said loop being open at its inner end and adapted to be disposed about the intermediate border wire of said mattress.
Claim 7
Dependent Claim
28 words
The combination of claim 4 including bends in the inwardly extending portions of said spring portions to define substantially parallel extensions, said extensions terminating in said anchor loop.
Claim 8
Dependent Claim
140 words
A single piece edge stiffener for mattresses of the type having upper, lower and intermediate border wires wherein the intermediate wire is inwardly disposed of the mattresses from the upper and lower wires, said stiffener comprising: a pair of oppositely projecting mounting arms at the extended ends thereof adapted to be carried by the upper and lower border wires of the mattress respectively, each of said arms bending at the inner ends thereof, at substantially right angles, to define a pair of coplanar cantelever spring portions, said spring portions extending inwardly of said arms and bending at the inwardly extending ends thereof to define a pair of substantially parallel extensions, said extensions terminating in a semi-circular anchor loop, said anchor loop being open at its inner end and adapted to be disposed about said intermediate border wire of said mattress.
