Abstract
Abstract A body limb support comprising a limb encircling member comprising knitted thread wherein the outer parts of the knitted thread in a relaxed state on a substantial portion of the inner surface of the limb encircling member have attached thereto a nonadhesive, noncontinuous, relatively soft, elastomeric polymeric material with a high coefficient of friction to skin so as to provide a nonocclusive slip resistant surface capable of maintaining the support in place on the limb of the body.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
77 words
A body limb support comprising a limb encircling member comprising knitted thread having a nonadhesive, non-continuous, relatively soft, elastomeric polymeric material with a high coefficient of friction to skin attached to the outer parts of the knitted thread in a relaxed state on a substantial portion of the inner surface of the limb encircling member, the polymeric material comprising a nonocclusive, slip resistant surface capable of maintaining the support in place on the limb of the body.
Claim 2
Dependent Claim
77 words
A body limb support comprising a limb encircling member comprising knitted thread having a nonadhesive, non-continuous, relatively soft, elastomeric polymeric material with a high coefficient of friction to skin attached to the outer parts of the knitted thread in a relaxed state on a substantial portion of the inner surface of the limb encircling member, the polymeric material comprising a nonocclusive, slip resistant surface capable of maintaining the support in place on the limb of the body.
Claim 3
Dependent Claim
14 words
The body limb support of claim 1 wherein said knitted thread comprises elastomeric thread.
Claim 4
Dependent Claim
37 words
The body limb support of claim 1 wherein at least 50 percent of the inner surface of the limb encircling member has polymeric material attached to the outer parts of the knitted thread in a relaxed state.
Claim 5
Dependent Claim
37 words
The body limb support of claim 1 wherein at least 90 percent of the inner surface of the limb encircling member has polymeric material attached to the outer parts of the knitted thread in a relaxed state.
Claim 6
Dependent Claim
14 words
The body limb support of claim 1 wherein the polymeric material is acrylic polymer.
Claim 7
Dependent Claim
79 words
A stocking comprising a foot portion and a leg portion comprising knitted thread having a nonadhesive, noncontinuous, relatively soft, elastomeric polymeric material with a high coefficient of friction to skin attached to the outer parts of the knitted thread in a relaxed state on a substantial portion of the inner surface of the leg portion of the stocking, the polymeric material comprising a non-occlusive, slip-resistant surface capable of maintaining the stocking in place on the leg of the body.
Claim 8
Dependent Claim
79 words
A stocking comprising a foot portion and a leg portion comprising knitted thread having a nonadhesive, noncontinuous, relatively soft, elastomeric polymeric material with a high coefficient of friction to skin attached to the outer parts of the knitted thread in a relaxed state on a substantial portion of the inner surface of the leg portion of the stocking, the polymeric material comprising a non-occlusive, slip-resistant surface capable of maintaining the stocking in place on the leg of the body.
Claim 9
Dependent Claim
12 words
The stocking of claim 6 wherein said knitted thread comprises elastomeric thread.
Claim 10
Dependent Claim
37 words
The stocking of claim 7 wherein at least 50 percent of the inner surface of the leg portion of the stocking has polymeric material attached to the outer parts of the knitted thread in a relaxed state.
Claim 11
Dependent Claim
19 words
The stocking of claim 8 wherein the leg portion of the stocking extends from the ankle to the knee.
Claim 12
Dependent Claim
37 words
The stocking of claim 9 wherein at least 90 percent of the inner surface of the leg portion of the stocking has polymeric material attached to the outer parts of the knitted thread in a relaxed state.
Claim 13
Dependent Claim
49 words
The stocking of claim 7 wherein the leg portion extends from the ankle through the thigh and wherein at least 50 percent of the inner surface of the leg portion of the stocking has polymeric material attached to the outer parts of the knitted threads in a relaxed state.
Claim 14
Dependent Claim
12 words
The stocking of claim 6 wherein the polymeric material is acrylic polymer.
Claim 15
Dependent Claim
72 words
A process for preparing a nonocclusive, slip-resistant body limb support comprising a limb encircling member comprising knitted thread comprising applying an elastomeric, polymeric material having a high coefficient of friction to skin capable of drying to a nonadhesive state onto the outer parts of the knitted thread in a relaxed state of a substantial portion of the inner surface of the limb encircling member and drying said polymeric material on said thread.
Claim 16
Dependent Claim
72 words
A process for preparing a nonocclusive, slip-resistant body limb support comprising a limb encircling member comprising knitted thread comprising applying an elastomeric, polymeric material having a high coefficient of friction to skin capable of drying to a nonadhesive state onto the outer parts of the knitted thread in a relaxed state of a substantial portion of the inner surface of the limb encircling member and drying said polymeric material on said thread.
Claim 17
Dependent Claim
20 words
The process of claim 13 wherein the polymeric material is applied by spraying the polymeric material onto said knitted thread.
Claim 18
Dependent Claim
33 words
The process of claim 14 wherein the polymeric material is sprayed in a fine mist and the particles of polymeric material in said mist are partially dry upon contact with said knitted thread.
