Abstract
Abstract A reusable knee support structure comprises an inner layer of a resilient material, such as neoprene rubber, and an outer layer of a relatively non-resilient but flexible material, such as Dacron® sail cloth, that is secured as a pair of mirror image sections to the outside surface of the inner layer. A pair of articulated linkages, each made of a material such as roller or bicycle chain, is disposed between the inner and outer layers on each side of the center line of the support structure. The resilient layer is snugly wrapped around the knee of a human with an aperture in the inner layer positioned over the kneecap. Hook and loop fastening panels may be secured to the structure to facilitate its application.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
148 words
A reusable support structure for application to the knee of a human comprising: A. an inner layer i. formed of a relatively resilient material, ii. having dimensions that enable said layer to be resiliently wrapped around the knee, and iii. having an inside surface for facing inwardly against the knee and an outside surface; B. an outer layer i. comprising first and second separate, essentially mirror image sections secured in spaced apart positions to the outside surface of said inner layer, and ii. each of said outer layer sections being formed of a relatively non-resilient flexible material; and C. articulated linking means i. positioned between said inner layer and one of said separate outer layers, and ii. being secured within said structure such that said means are relatively inflexible to twisting and lateral forces applied to it while providing for relatively free flexing and extension of the knee.
Claim 2
Dependent Claim
148 words
A reusable support structure for application to the knee of a human comprising: A. an inner layer i. formed of a relatively resilient material, ii. having dimensions that enable said layer to be resiliently wrapped around the knee, and iii. having an inside surface for facing inwardly against the knee and an outside surface; B. an outer layer i. comprising first and second separate, essentially mirror image sections secured in spaced apart positions to the outside surface of said inner layer, and ii. each of said outer layer sections being formed of a relatively non-resilient flexible material; and C. articulated linking means i. positioned between said inner layer and one of said separate outer layers, and ii. being secured within said structure such that said means are relatively inflexible to twisting and lateral forces applied to it while providing for relatively free flexing and extension of the knee.
Claim 3
Dependent Claim
22 words
A support structure as recited in claim 1, further comprising an aperture in said inner layer sized for positioning over the kneecap
Claim 4
Dependent Claim
101 words
A support structure as recited in claim 2, wherein said inner layer includes first and second opposed side members, in which said first side member extends outwardly from the center of said inner layer through a greater distance than said second side member, in which said first and second outer layers are secured over said first and second inner layers, respectively, such that a portion of said second outer layer extends beyond the end of said second inner layer, the extended portion of said second outer layer overlaps said first outer layer when said inner layer is wrapped around the knee.
Claim 5
Dependent Claim
25 words
A support structure as recited in claim 3, wherein said articulated linking means are two articulated linking means disposed on opposite sides of said knee.
Claim 6
Dependent Claim
31 words
A support structure as recited in claim 2 wherein said aritculated linking means are two roller chains having relatively small, uniformly sized links and positioned on opposite sides of the knee.
Claim 7
Dependent Claim
19 words
A support structure as recited in claim 5, wherein said chains are positioned between said layers in a V-shape.
Claim 8
Dependent Claim
53 words
A support structure as recited in claim 1, further comprising a resilient internal layer positioned between said articulated linking means and said inner layer; said articulated linking means being secured to said internal layer which is in turn secured to said inner layer, said internal layer thereby providing further padding for the knee.
Claim 9
Dependent Claim
50 words
A support structure as recited in claim 1 further comprising a fastening panel of a first type secured to said first separate outer layer section and a fastening panel of a second, cooperating type secured to said second separate outer layer section for removably securing said structure around said knee.
Claim 10
Dependent Claim
18 words
A support structure as recited in claim 1 in which said inner layer is formed from neoprene rubber.
Claim 11
Dependent Claim
19 words
A support structure as recited in claim 1 in which said outer layer sections are formed of Dacron® sailcloth.
Claim 12
Dependent Claim
24 words
A support structure as recited in claim 1 wherein said articulated linking means are two roller chains positioned on opposite sides of the kneecap.
Claim 13
Dependent Claim
39 words
A support structure as recited in claim 11 wherein said roller chains have two flat sides which are positioned so that one of their flat sides face the inner layer while their other flat sides face the outer layer.
Claim 14
Dependent Claim
101 words
A reusable support structure for application to a knee of a user comprising: an inner layer having dimensions that enable said layer to be wrapped around the knee of the user, said inner layer having an inside surface adapted to face inwardly against the knee and an outer surface, an outer layer centered about the kneecap secured to said inner layer, a roller chain and having a plurality of relatively small, uniformly sized linkages, said chain being disposed between said inner and outer layers and positioned on one side of the knee, and means for securing said structure around the knee.
Claim 15
Dependent Claim
101 words
A reusable support structure for application to a knee of a user comprising: an inner layer having dimensions that enable said layer to be wrapped around the knee of the user, said inner layer having an inside surface adapted to face inwardly against the knee and an outer surface, an outer layer centered about the kneecap secured to said inner layer, a roller chain and having a plurality of relatively small, uniformly sized linkages, said chain being disposed between said inner and outer layers and positioned on one side of the knee, and means for securing said structure around the knee.
Claim 16
Dependent Claim
21 words
A support structure as recited in claim 13, wherein said roller chain is positioned between said layers in a Z-shaped fashion.
Claim 17
Dependent Claim
20 words
A support structure as recited in claim 13, wherein said chain is positioned between said layers in a S-shaped fashion.
Claim 18
Dependent Claim
20 words
A support structure as recited in claim 13, wherein said chain is positioned between said layers in an oviod-shaped fashion.
Claim 19
Dependent Claim
48 words
A support structure as recited in claim 13, further comprising a second roller chain having a plurality of relatively small, uniformly sized linkages, said second roller chain being disposed between said inner and outer layers and positioned on the opposite side of the knee from said first-named chain.
Claim 20
Dependent Claim
19 words
A support structure as recited in claim 13, wherein said outer layer is formed of a non-resilient, flexible material.
Claim 21
Dependent Claim
18 words
A support structure as recited in claim 18, wherein said inner layer is formed of a resilient material.
Claim 22
Dependent Claim
28 words
A support structure as recited in claim 18, wherein said structure defines an aperture disposed such that it is adapted for positioning at the back of the knee.
