Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
206 words
An elasticized knit-fabric seamless garment adapted to substantially fit an anatomic form such as a human limb and exhibiting throughout the length of some predetermined portion of such garment when fitted to said form at each of plural reference locations, such as at the ankle, calf, knee, lower and upper thigh locations on the leg, spaced apart by some plural number of uniform predetermined increments of lengthwise measurement which number may vary between selected successive reference locations, a predetermined amount of compression representing a known percentage of the compression at one of the reference locations and at locations between each pair of such reference locations predetermined amounts of compression graduated in a controlled amount such that in said predetermined portion a plurality of said reference locations are included and starting at a beginning reference location, e.g. the ankle, and ending at an end reference location, e.g. the upper thigh, the compression from each reference location to the next successive reference location throughout said predetermined portion changes in a substantially linear relation and providing an overall non-linear change between said beginning and end reference locations and exclusively linear changes between each pair of said reference locations and exclusively linear changes between each pair of said reference locations.
Claim 2
Dependent Claim
206 words
An elasticized knit-fabric seamless garment adapted to substantially fit an anatomic form such as a human limb and exhibiting throughout the length of some predetermined portion of such garment when fitted to said form at each of plural reference locations, such as at the ankle, calf, knee, lower and upper thigh locations on the leg, spaced apart by some plural number of uniform predetermined increments of lengthwise measurement which number may vary between selected successive reference locations, a predetermined amount of compression representing a known percentage of the compression at one of the reference locations and at locations between each pair of such reference locations predetermined amounts of compression graduated in a controlled amount such that in said predetermined portion a plurality of said reference locations are included and starting at a beginning reference location, e.g. the ankle, and ending at an end reference location, e.g. the upper thigh, the compression from each reference location to the next successive reference location throughout said predetermined portion changes in a substantially linear relation and providing an overall non-linear change between said beginning and end reference locations and exclusively linear changes between each pair of said reference locations and exclusively linear changes between each pair of said reference locations.
Claim 3
Dependent Claim
20 words
An elasticized knit-fabric garment as set forth in claim 1 wherein said garment comprises a tubular circular knit elasticized garment.
Claim 4
Dependent Claim
91 words
An elasticized knit fabric garment as set forth in claim 2 wherein said garment comprises a compressive stocking adapted to fit a leg upwardly from the ankle and the amount of compression asserted at each said reference location in the finished compressive stocking is substantially equal to some known percentage of the compression asserted at the ankle location thereof and said linear relation corresponds to each change from one said known percentage of compression at one reference location to the said known percentage of compression at the next said reference location.
Claim 5
Dependent Claim
41 words
An elasticized knit fabric garment as set forth in claim 2 including a panel insert joined so as to form a portion of said tubular fabric and having compression characteristics consistent with the compression characteristics of the remainder of said fabric.
