Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 222 words
An inflatable foot support device comprising: a. a plurality of walls joined together to form a closed chamber having one generally upright wall thereof engageable by feet of a supine person; b. said chamber has laterally spaced side walls and vertically spaced top and bottom walls each having opposite ends and spaced end walls extending between said side walls and respective ends of said top and bottom walls; c. means on one of said chamber walls to permit communication of air into said chamber to inflate same; d. means connected to and extending from said chamber walls for removably securing said chamber in a selected position on a bed; e. said means for securing said chamber in a selected position on a bed comprises a strap for each end of said bottom wall and extending outwardly therefrom with each of said straps having a fastening member thereon; f. said bottom wall and said straps are a one piece member; g. said top wall and said end walls are a one piece member; h. said end walls each have an end portion secured to said bottom wall; and i. said side walls each have a peripheral edge flange having respective portions thereof secured to said bottom wall and to said top wall and to said end walls to thereby define the closed chamber.
Claim 2
Dependent Claim 222 words
An inflatable foot support device comprising: a. a plurality of walls joined together to form a closed chamber having one generally upright wall thereof engageable by feet of a supine person; b. said chamber has laterally spaced side walls and vertically spaced top and bottom walls each having opposite ends and spaced end walls extending between said side walls and respective ends of said top and bottom walls; c. means on one of said chamber walls to permit communication of air into said chamber to inflate same; d. means connected to and extending from said chamber walls for removably securing said chamber in a selected position on a bed; e. said means for securing said chamber in a selected position on a bed comprises a strap for each end of said bottom wall and extending outwardly therefrom with each of said straps having a fastening member thereon; f. said bottom wall and said straps are a one piece member; g. said top wall and said end walls are a one piece member; h. said end walls each have an end portion secured to said bottom wall; and i. said side walls each have a peripheral edge flange having respective portions thereof secured to said bottom wall and to said top wall and to said end walls to thereby define the closed chamber.
Claim 3
Dependent Claim 380 words
An inflatable foot support device comprising: a. a plurality of flexible walls joined together to form a closed chamber having one wall thereof engageable by feet of a supine person, said chamber being inflatable and substantially air tight; b. valve means on one of said chamber walls to permit communication of air into said chamber to inflate same; c. a pair of opposed straps extending from said chamber, said straps each being engageabLe with a respective portion of a bed frame; d. means on each of said straps for removably securing same in engagement with the respective portion of the bed frame; e. said chamber has laterally spaced side walls and vertically spaced top and bottom walls each having opposite ends and spaced end walls extending between said side walls and respective ends of said top and bottom walls; f. said pair of straps are arranged with a respective one of said straps extending from each of the opposite ends of said bottom wall; g. each of said straps has a plurality of longitudinally spaced apertures therein and a fastening member thereon to be received in a selected one of said respective apertures; h. said bottom wall has a length substantially greater than a length of said top wall; i. said top and bottom walls and said end walls each have a length substantially greater than a width thereof; j. said end walls are each arranged to define an acute angle between each of said respective end walls and said bottom wall and an acute angle between each of said respective end walls and said top wall; k. said bottom wall and said pair of straps are a one piece member; l. said bottom wall and said pair of straps have a thickness greater than a thickness of the other walls of the plurality of walls of said chamber; m. said top wall and said end walls are a one piece member; n. said end walls each have an end portion extending therefrom and secured to said bottom wall at respective opposite ends of said bottom wall; and o. said side walls each have peripheral edge flange portions secured to said bottom wall and to said top wall and to said end walls respectively to thereby define the closed chamber.
Claim 4
Dependent Claim 380 words
An inflatable foot support device comprising: a. a plurality of flexible walls joined together to form a closed chamber having one wall thereof engageable by feet of a supine person, said chamber being inflatable and substantially air tight; b. valve means on one of said chamber walls to permit communication of air into said chamber to inflate same; c. a pair of opposed straps extending from said chamber, said straps each being engageabLe with a respective portion of a bed frame; d. means on each of said straps for removably securing same in engagement with the respective portion of the bed frame; e. said chamber has laterally spaced side walls and vertically spaced top and bottom walls each having opposite ends and spaced end walls extending between said side walls and respective ends of said top and bottom walls; f. said pair of straps are arranged with a respective one of said straps extending from each of the opposite ends of said bottom wall; g. each of said straps has a plurality of longitudinally spaced apertures therein and a fastening member thereon to be received in a selected one of said respective apertures; h. said bottom wall has a length substantially greater than a length of said top wall; i. said top and bottom walls and said end walls each have a length substantially greater than a width thereof; j. said end walls are each arranged to define an acute angle between each of said respective end walls and said bottom wall and an acute angle between each of said respective end walls and said top wall; k. said bottom wall and said pair of straps are a one piece member; l. said bottom wall and said pair of straps have a thickness greater than a thickness of the other walls of the plurality of walls of said chamber; m. said top wall and said end walls are a one piece member; n. said end walls each have an end portion extending therefrom and secured to said bottom wall at respective opposite ends of said bottom wall; and o. said side walls each have peripheral edge flange portions secured to said bottom wall and to said top wall and to said end walls respectively to thereby define the closed chamber.
