Abstract
Abstract A circular knit therapeutic stocking in which bare elastomeric yarn is knit in selected courses and wales with a non-elastomeric yarn in other selected courses and wales in the welt, boot and foot portions of a stocking to provide a retractive or compressive force of graduating degrees as required with a circumferential heel-instep band of lesser retractive or compressive force, and a closed toe area in which stretchable fabric with minimal retractive forces is integrally knit to the foot portion of the stocking whereby the bare elastomeric yarns are buried or concealed by the knitted non-elastomeric yarns and in which a welt panel of flexible and relatively non-stretchable material is secured in the welt portion of the stocking to be positioned on the inner upper thigh of the leg of a wearer. The inner surface of the welt panel being lined with polyurethane foam or similar material which would have a high coefficient of friction against the skin in order to help maintain the stocking in position on the leg of a wearer.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
166 words
A circular knit therapeutic stocking having foot, leg and welt portions, said foot, leg and welt portions having alternate wales with stitches of non-elastomeric yarn and intermediate wales in which alternate stitches of non-elastomeric yarn connect with intermediate stitches of bare elastomeric yarn in each said intermediate wale, said bare elastomeric yarn stitches being substantially dominated by said non-elastomeric yarn stitches whereby said bare elastomeric yarn stitches are protected by said non-elastomeric yarn stitches from direct contact with the leg of a wearer while providing graduated compressive force on the leg of a wearer, said foot portion having a closed toe portion, said welt portion of said stocking having an upper terminal portion and a longitudinal slit providing opposed edges, a flexible relatively non-stretchable downwardly-converging panel secured to said slit opposed edges in the welt portion, said panel extending at the upper terminal portion for less than 180° and converging downwardly, said panel engaging the inside of the upper thigh of the leg of a wearer.
Claim 2
Dependent Claim
166 words
A circular knit therapeutic stocking having foot, leg and welt portions, said foot, leg and welt portions having alternate wales with stitches of non-elastomeric yarn and intermediate wales in which alternate stitches of non-elastomeric yarn connect with intermediate stitches of bare elastomeric yarn in each said intermediate wale, said bare elastomeric yarn stitches being substantially dominated by said non-elastomeric yarn stitches whereby said bare elastomeric yarn stitches are protected by said non-elastomeric yarn stitches from direct contact with the leg of a wearer while providing graduated compressive force on the leg of a wearer, said foot portion having a closed toe portion, said welt portion of said stocking having an upper terminal portion and a longitudinal slit providing opposed edges, a flexible relatively non-stretchable downwardly-converging panel secured to said slit opposed edges in the welt portion, said panel extending at the upper terminal portion for less than 180° and converging downwardly, said panel engaging the inside of the upper thigh of the leg of a wearer.
Claim 3
Dependent Claim
50 words
A circular knit therapeutic stocking as claimed in claim 1, said toe portion having an integrally knit circumferential band of knit stretchable non-elastomeric fabric, and said panel having at least one soft ply of polyurethane foam to engage the inside of the upper thigh of the leg of a wearer.
Claim 4
Dependent Claim
79 words
A circular knit therapeutic stocking as claimed in claim 1, said flexible panel having two plies, one of said plies being an inner ply layer of relatively thin and soft polyurethane foam, and an outer ply layer of fabric of untextured nylon yarns, said inner and outer plies being securely fastened to each other and to the opposed edges in the welt whereby the foam ply will engage the inside upper thigh area of the leg of a wearer.
Claim 5
Dependent Claim
118 words
A circular knit therapeutic stocking as claimed in claim 1, said intermediate bare elastomeric yarn stitches and alternate non-elastomeric yarn stitches form intermediate courses, said intermediate bare elastomeric yarn stitches being connected continuously by a floated stitch of the same bare elastomeric yarn extending across alternate non-elastomeric stitches, and said relatively non-stretchable panel in the welt portion having two plies, an inner ply layer of relatively thin and soft polyurethane foam, and an outer ply layer of warp knit fabric of untextured nylon yarns, said inner and outer plies being securely fastened to each other and to the opposed edges in the welt whereby the foam will engage the inside upper thigh of the leg of a wearer.
