Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
533 words
A knee support comprising, a panel of soft, relatively thick pad material having a main interior and exterior surface and a top, bottom and side edges, said top edge being sized to extend substantially, but not completely, around the girth of the thigh of a wearer above the knee cap, said bottom edge being sized to extend substantially, but not completely, around the girth of the leg of a wearer below the knee cap, said side edges converging from the top edge to the bottom edge and having a cutout in the central portion defining a knee cap opening between the side edges when the panel is arranged about the knee of a wearer; first pocket means on the exterior surface of the panel extending substantially between the top and bottom edge in the central zone of the panel between the side edges to overlay the rear of the leg of a wearer, first stay means comprising an elongate length of flexible material of predetermined flex characteristic in said first pocket means and extending substantially between the top and bottom edges; a pair of second pocket means, one of said pairs adjacent each of the side edges and extending upwardly and downwardly from the lateral center line of the panel about one-half the distance between said lateral center line and the top and bottom edges respectively; a plurality of elongate second stay means nested within the second pocket means to provide lateral and medial support to the knee of a wearer; attachmeNt means to hold the support about the knee of a wearer comprising, an upper elastic strip laterally extending from the upper portion of one of the side edges adjacent the top edge and of a length to span the gap between the side edges when the support is placed about the thigh of a wearer; a lower elastic strip laterally extending from the lower portion of one of said side edges and adjacent the bottom edge and of a length to span the gap between the side edges of the panel when the support is placed about the leg of a wearer below the knee cap; first mutually intercooperating connector means on the terminal end of the upper and lower elastic strips and on the exterior surface of the panel adjacent the side edge opposite to said one of the side edges; a central laterally extending elastic strip connected at one end to the central zone of the panel of a height extending above and below the lateral center line of the panel about three inches and of a lateral length extending (about 5 inches) from the intersection of the lateral center line and the side edge opposite to said one of said side edges sufficient to overlap the exterior surface of the panel when the support is placed about the leg of a wearer with the strip overlaying the knee cap and in a stretched condition; second connector means on the terminal end of the central laterally extending strip and on the exterior of said panel to connect the terminal end zone of the central elastic strip to said panel with said central elastic strip overlaying said knee cap opening.
Claim 2
Dependent Claim
533 words
A knee support comprising, a panel of soft, relatively thick pad material having a main interior and exterior surface and a top, bottom and side edges, said top edge being sized to extend substantially, but not completely, around the girth of the thigh of a wearer above the knee cap, said bottom edge being sized to extend substantially, but not completely, around the girth of the leg of a wearer below the knee cap, said side edges converging from the top edge to the bottom edge and having a cutout in the central portion defining a knee cap opening between the side edges when the panel is arranged about the knee of a wearer; first pocket means on the exterior surface of the panel extending substantially between the top and bottom edge in the central zone of the panel between the side edges to overlay the rear of the leg of a wearer, first stay means comprising an elongate length of flexible material of predetermined flex characteristic in said first pocket means and extending substantially between the top and bottom edges; a pair of second pocket means, one of said pairs adjacent each of the side edges and extending upwardly and downwardly from the lateral center line of the panel about one-half the distance between said lateral center line and the top and bottom edges respectively; a plurality of elongate second stay means nested within the second pocket means to provide lateral and medial support to the knee of a wearer; attachmeNt means to hold the support about the knee of a wearer comprising, an upper elastic strip laterally extending from the upper portion of one of the side edges adjacent the top edge and of a length to span the gap between the side edges when the support is placed about the thigh of a wearer; a lower elastic strip laterally extending from the lower portion of one of said side edges and adjacent the bottom edge and of a length to span the gap between the side edges of the panel when the support is placed about the leg of a wearer below the knee cap; first mutually intercooperating connector means on the terminal end of the upper and lower elastic strips and on the exterior surface of the panel adjacent the side edge opposite to said one of the side edges; a central laterally extending elastic strip connected at one end to the central zone of the panel of a height extending above and below the lateral center line of the panel about three inches and of a lateral length extending (about 5 inches) from the intersection of the lateral center line and the side edge opposite to said one of said side edges sufficient to overlap the exterior surface of the panel when the support is placed about the leg of a wearer with the strip overlaying the knee cap and in a stretched condition; second connector means on the terminal end of the central laterally extending strip and on the exterior of said panel to connect the terminal end zone of the central elastic strip to said panel with said central elastic strip overlaying said knee cap opening.
Claim 3
Dependent Claim
17 words
The device as set forth in claim 1 wherein the material of said panel is of felt.
Claim 4
Dependent Claim
162 words
The device as set forth in claim 1 wherein said first and second mutually intercooperating means comprise a pair of soft nap loops constituting keeper means arranged medially on the face of the strips facing the panel and a companionate array of hook means on the exterior surface of the panel which confronts the strips when the strips are in overlaying relation of the knee zone of a wearer, said hook means comprising a pattern of outwardly projecting, commonly oriented, hook members in upstanding relation adapted in response to pressure against said nap loops to inter-mesh with said loops and releasably cling to the nap of said pads to be separated therefrom in response to a peeling or quick yanking force, whereby, when the elastic strips are stretched longitudinally from their respective zones of attachment to the panel and wrapped inwardly and forwardly about the knee zone of a wearer, said hook means are adapted for hooked-up engagement with said nap loops.
Claim 5
Dependent Claim
30 words
The device as set forth in claim 1 wherein flexible reinforcing means in sheet form are provided and connected to the exterior surface of the panel to strengthen the same.
Claim 6
Dependent Claim
51 words
The device as set forth in claim 1 wherein the convergence of the side edges traces a curve from the bottom edges toward but not to the top edges and the curve traced by said side edges is generally vertical between the top edge and the intersection with the curved portion.
Claim 7
Dependent Claim
36 words
The device as set forth in claim 1 wherein said first pocket means are open adjacent the upper edge to facilitate removal of the first stay means and replacement with stay means of different flex characteristics.
Claim 8
Dependent Claim
39 words
The device as set forth in claim 1 wherein the pair of second pocket means are open at their upper end zones to remove said second stay means and replace the same with stay means of different flex characteristics.
