Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
140 words
An adjustable foot support comprising a unitary supporting platform, and a unitary base with a plurality of stepped adjustment brackets at one end thereof, said brackets extending upwardly from said base and each of said brackets having a plurality of stepped horizontal channels, means extending downwardly from said platform to selectively cooperate with said stepped channels so that said platform is selectively inclined with respect to said base, and hinge means connecting said supporting platform with said base so that said platform is movably attached to said base, said hinge means including a plurality of overhangs carried by a plurality of walls extending upwardly from said base, said overhang and walls forming a partially enclosed socket, and hinge pin means depending from said platform and located within said socket, said pin means freely movable within said socket and retained therein.
Claim 2
Dependent Claim
140 words
An adjustable foot support comprising a unitary supporting platform, and a unitary base with a plurality of stepped adjustment brackets at one end thereof, said brackets extending upwardly from said base and each of said brackets having a plurality of stepped horizontal channels, means extending downwardly from said platform to selectively cooperate with said stepped channels so that said platform is selectively inclined with respect to said base, and hinge means connecting said supporting platform with said base so that said platform is movably attached to said base, said hinge means including a plurality of overhangs carried by a plurality of walls extending upwardly from said base, said overhang and walls forming a partially enclosed socket, and hinge pin means depending from said platform and located within said socket, said pin means freely movable within said socket and retained therein.
Claim 3
Dependent Claim
76 words
An adjustable foot support comprising a unitary supporting platform, and a unitary base with a plurality of stepped adjustment brackets at one end thereof, said brackets including a plurality of supports extending upwardly from said base and joined by a plurality of arcuate links defining a plurality of stepped horizontal channels, means extending downwardly from said platform to selectively cooperate with said arcuate links so that said platform is selectively inclined with respect to said base.
Claim 4
Dependent Claim
76 words
An adjustable foot support comprising a unitary supporting platform, and a unitary base with a plurality of stepped adjustment brackets at one end thereof, said brackets including a plurality of supports extending upwardly from said base and joined by a plurality of arcuate links defining a plurality of stepped horizontal channels, means extending downwardly from said platform to selectively cooperate with said arcuate links so that said platform is selectively inclined with respect to said base.
Claim 5
Dependent Claim
17 words
A device according to claim 2 wherein said means extending downwardly from said platform is a leg.
Claim 6
Dependent Claim
40 words
A device according to claim 2 further comprising hinge means connecting said supporting platform with said base so that said platform is movably attached to said base when said means extending downwardly from said platform selectively engages said stepped channels.
Claim 7
Dependent Claim
47 words
A device according to claim 2 further comprising rail means extending upwardly from said base and bar means depending from said support platform, said bar means and said rail means cooperatively defining the maximum elevation and angle of inclination of said platform with respect to said base.
Claim 8
Dependent Claim
56 words
A device according to claim 5 wherein said rail means includes an eave carried by a post, said eave outwardly extending from the perimeter of said base, further wherein said bar means includes an inwardly extending lip, said eave and lip positioned so as to engage when said platform is selectively inclined beyond said predetermined angle.
