Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
197 words
A novel exercise assembly upon which a human may assume a straddled position for improving leg flexibility, which comprises: an elongated base support assembly; a body support assembly including a center support member longitudinally disposed on said elongated base support assembly, and a first side platform having a first end portion thereof hinged to said center support member along a first longitudinal axis, said first side platform having a length sufficient to permit a second end portion of said first side platform to extend down and engage a foundation surface; and means for lowering and raising said body support assembly between a first vertical position and a second vertical position below said first vertical position, whereby upon lowering said body support assembly from said first vertical position to said second vertical position, said first longitudinal axis is lowered, said second end portion of said first platform moves transversely along said foundation surface, and said first side platform rotates about said lowered first longitudinal axis in an angular direction away from a vertical position, said means for lowering and raising said body support assembly being operable when a human has assumed a straddle position on said exercise assembly.
Claim 2
Dependent Claim
197 words
A novel exercise assembly upon which a human may assume a straddled position for improving leg flexibility, which comprises: an elongated base support assembly; a body support assembly including a center support member longitudinally disposed on said elongated base support assembly, and a first side platform having a first end portion thereof hinged to said center support member along a first longitudinal axis, said first side platform having a length sufficient to permit a second end portion of said first side platform to extend down and engage a foundation surface; and means for lowering and raising said body support assembly between a first vertical position and a second vertical position below said first vertical position, whereby upon lowering said body support assembly from said first vertical position to said second vertical position, said first longitudinal axis is lowered, said second end portion of said first platform moves transversely along said foundation surface, and said first side platform rotates about said lowered first longitudinal axis in an angular direction away from a vertical position, said means for lowering and raising said body support assembly being operable when a human has assumed a straddle position on said exercise assembly.
Claim 3
Dependent Claim
134 words
An exercise assembly as defined in claim 1 wherein said body support assembly includes a second side platform having one end portion thereof hinged to said center support member along a second longitudinal axis, said second side platform having a length sufficient to permit a second end portion of said second side platform to extend down and engage said foundation surface, whereby upon lowering said body support assembly from said first vertical position to said second vertical position, said second longitudinal axis is lowered, said second end portion of said second side platform moves transversely along said foundation surface, and said second side platform rotates about said lowered second longitudinal axis in an angular direction away from a vertical position, in a rotational direction opposite to the rotational movement of said first said platform.
Claim 4
Dependent Claim
56 words
The novel exercise assembly as defined in claim 1 wherein said base support assembly is comprised of a front side frame assembly and a back side frame assembly, and an upper mounting member disposed between said front and back side frame assemblies, and wherein said center support member is longitudinally disposed upon said upper mounting member.
Claim 5
Dependent Claim
117 words
The novel exercise assembly as defined in claim 3 wherein said means for lowering and raising said body support assembly includes vertically disposed elongated threaded rod members including sprocket members fixedly mounted on said front and rear side frame assemblies, a chain coursed between said sprocket members, one of said elongated threaded rod members being provided with a handle to rotate said one of said elongated rod members, and wherein said upper mounting member includes threaded elements for engaging said elongated threaded rod members, whereby rotation of said handle causes simultaneous rotation of said elongated threaded rod members to alter the relative vertical position of said upper mounting member and said central support member longitudinally positioned thereon.
Claim 6
Dependent Claim
59 words
The novel exercise assembly as defined in claim 1 wherein said first side platform is provided with roller means in the vicinity of said second end portion thereof, for riding on said foundation surface to facilitate transverse movement on said foundation surface as said body support assembly is lowered from said first vertical position to said second vertical position.
Claim 7
Dependent Claim
88 words
The novel exercise assembly in accordance with claim 2, wherein said first side platform is provided with first roller means in the vicinity of said second end portion thereof, and said second side platform is provided with second roller means in the vicinity of said second end portion thereof, said first and second roller means facilitating opposite direction, transverse movements of said first and second side platforms on said foundation surface as said body support assembly is lowered from said first vertical position to said second vertical position.
