Abstract A joint support apparatus for wrapping around a joint to protect and support the joint during sports-like or sports-related activities. The main body of the apparatus being made of at least one sheet of flexible resilient material and constructed to urge the knee-joint to maintain a partially flexed position. The apparatus may also include a specially positioned pad to account for natural curvature of the knee-joint to maintain a more balanced support to the joint particularly during extension. Further the apparatus may also include an inflatable bladder.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
161 words
A brace for supporting and restricting movement of a joint of a limb of a user, the brace comprising: a main body formed of at least one layer of flexible, resilient material for providing support to and restricted movement of a joint of a user; attachment means connected to the main body for releasably attaching the brace to the user's joint; an inflatable bladder attached to the main body, said bladder consisting essentially of only two parallel arms and an integrally formed generally annular portion positioned between said parallel arms; said parallel arms for engaging only each side of the joint parallel to the limb when said brace is in use and said parallel arms providing lateral support to the user's joint when the parallel arms are applied to opposing sides of the user's joint parallel to the limb; and said generally annular portion adapted to substantially encircle the user's joint for additional adjustment support and cushioning to the user's joint.
Claim 2
Dependent Claim
161 words
A brace for supporting and restricting movement of a joint of a limb of a user, the brace comprising: a main body formed of at least one layer of flexible, resilient material for providing support to and restricted movement of a joint of a user; attachment means connected to the main body for releasably attaching the brace to the user's joint; an inflatable bladder attached to the main body, said bladder consisting essentially of only two parallel arms and an integrally formed generally annular portion positioned between said parallel arms; said parallel arms for engaging only each side of the joint parallel to the limb when said brace is in use and said parallel arms providing lateral support to the user's joint when the parallel arms are applied to opposing sides of the user's joint parallel to the limb; and said generally annular portion adapted to substantially encircle the user's joint for additional adjustment support and cushioning to the user's joint.
Claim 3
Dependent Claim
33 words
The brace of claim 1 wherein the bladder includes a plurality of weld spots for providing flexibility to the bladder for allowing the bladder to conform to the shape of the user's joint.
Claim 4
Dependent Claim
19 words
The brace of claim 2 wherein the brace is shaped to conform to the user's knee or elbow joint.
Claim 5
Dependent Claim
39 words
The brace of claim 1, wherein the attachment means includes pairs of top and bottom flanges integral to the main body thereby forming a generally I-shaped brace wherein the flanges are adapted to be wrapped around the user's joint.
Claim 6
Dependent Claim
20 words
The brace of claim 4 wherein the pair of the top flanges is longer than the pair of bottom flanges.
Claim 7
Dependent Claim
29 words
The brace of claim 4 wherein the attachment means further includes mating portions of hook and pile fastening material attached to each of the top and bottom flange pairs.
Claim 8
Dependent Claim
57 words
The brace of claim 6 wherein the hook material of the top flange pair is attached to a flange on a side of the main body opposite from the hook material of the bottom flange pair for providing opposing forces between the top and bottom flange pairs for reducing rotation of the brace about the user's joint.
Claim 9
Dependent Claim
72 words
The brace of claim 4 further including: a pair of notches, formed on opposite sides of the main body between the top and bottom flanges for positioning on each side of the user's joint, each of said notches being a generally V-shaped notch and each of said notches is closed by connecting the two sides of each notch together such that the brace generally conforms to the shape of the user's joint.
Claim 10
Dependent Claim
48 words
The brace of claim 1 further including: structure defining a central aperture in the main body; a cap portion generally conforming to the shape of the main body aperture; and attachment means for releasably attaching the cap portion to the main body for covering the main body aperture.
Claim 11
Dependent Claim
16 words
The brace of claim 9 wherein the cap portion is formed of a resilient plastic material.
Claim 12
Dependent Claim
14 words
The brace of claim 1 wherein the attachment means includes hook and pile material.
