Abstract
Abstract For both orthopedic and sports uses, a foamed plastic pad is integrally molded to a fabric. More particularly, a knitted sleeve is constructed having a terry loop on the interior surface of a hydrophobic yarn (e.g. acrylic) and an exterior surface of a hydrophilic yarn (e.g. cotton), whereby moisture is wicked away from the surface in a hydrokinetic fashion. A soft, hydrophilic polyurethane foam pad, which acts as a sponge, absorbs the moisture, is molded integrally with the sleeve, leaving the terry loops free for skin contact. For sports uses, knitted or woven fabrics may be employed, and stiffer, polyurethane foams are preferred.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
75 words
A body-protecting pad comprising: a hydrokinetic sleeve of a knit fabric having an internal hydrophobic yarn and an external surface at least partially comprised of a hydrophilic yarn; an integral, hydrophilic polyurethane pad molded and foamed in situ into said external surface of said sleeve so as to be bonded to and at least partially embedded in said sleeve; whereby moisture can be wicked away from the wearer, through the fabric, and into the pad.
Claim 2
Dependent Claim
75 words
A body-protecting pad comprising: a hydrokinetic sleeve of a knit fabric having an internal hydrophobic yarn and an external surface at least partially comprised of a hydrophilic yarn; an integral, hydrophilic polyurethane pad molded and foamed in situ into said external surface of said sleeve so as to be bonded to and at least partially embedded in said sleeve; whereby moisture can be wicked away from the wearer, through the fabric, and into the pad.
Claim 3
Dependent Claim
18 words
The pad as claimed in claim 1, wherein: said sleeve is a terry knit having internal terry loops.
Claim 4
Dependent Claim
27 words
The pad is claimed is claim 1, wherein: said sleeve is part of an athletic uniform; and said pad is an integral skin, medium density, semi-rigid polyurethane.
Claim 5
Dependent Claim
22 words
The pad as claimed in claim 2, wherein said hydrophobic yarn is an acrylic, and said external surface comprises cotton and nylon.
Claim 6
Dependent Claim
74 words
A hydrokinetic orthopedic pad comprising: a knit terry sleeve having interior hydrophobic terry loops and a hydrophilic exterior surface; an integral, skinned hydrophilic polyurethane pad molded and foamed in situ into an external surface of said sleeve so as to be bonded to and at least partially embedded in said sleeve but leaving said terry loops substantially free; whereby moisture can be wicked away from the wearer, through the sleeve, and into the pad.
Claim 7
Dependent Claim
74 words
A hydrokinetic orthopedic pad comprising: a knit terry sleeve having interior hydrophobic terry loops and a hydrophilic exterior surface; an integral, skinned hydrophilic polyurethane pad molded and foamed in situ into an external surface of said sleeve so as to be bonded to and at least partially embedded in said sleeve but leaving said terry loops substantially free; whereby moisture can be wicked away from the wearer, through the sleeve, and into the pad.
Claim 8
Dependent Claim
27 words
The pad as claimed in claim 5, wherein said terry loops are formed of acrylic yarn and said exterior surface is formed of cotton and texturalized nylon.
