Abstract
Abstract A foot operated rotational assembly is provided which a user operates while in a standing position. The apparatus includes a rotational assembly mounted on a frame structure. The rotational assembly includes a plurality of rotatable members connected together by an intermediate rotatable member. Cranks are attached to and extend from each side of the rotatable members. A pedal is located on each side which bridges the cranks on that side. The cranks are arranged so that the pedals are opposingly positioned and travel their path of rotation while remaining in a horizontal position.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
159 words
A foot engageable rotational assembly comprising: a frame structure; a rotation assembly mounted on said frame structure, wherein said rotation assembly includes at least two rotatable members, said rotatable members being operatively connected together by an intermediate rotatable member, said intermediate rotatable member being in rolling contact with said rotatable members, thereby causing said rotatable members to rotate at the same angular velocity and acceleration; and foot engagement means connected to said rotational assembly, wherein said foot engagement means includes connection members and two foot engaging members, each of said foot engaging members being connected to one side of each of said rotatable members through said connection members such that both foot engaging members remain in a substantially horizontal position as the rotatable members rotate, said foot engaging members and said connection members being attaches along horizontal axes restricting relative movement to rotation about said axes; whereby a user may perform a cycling routine while in a standing position.
Claim 2
Dependent Claim
159 words
A foot engageable rotational assembly comprising: a frame structure; a rotation assembly mounted on said frame structure, wherein said rotation assembly includes at least two rotatable members, said rotatable members being operatively connected together by an intermediate rotatable member, said intermediate rotatable member being in rolling contact with said rotatable members, thereby causing said rotatable members to rotate at the same angular velocity and acceleration; and foot engagement means connected to said rotational assembly, wherein said foot engagement means includes connection members and two foot engaging members, each of said foot engaging members being connected to one side of each of said rotatable members through said connection members such that both foot engaging members remain in a substantially horizontal position as the rotatable members rotate, said foot engaging members and said connection members being attaches along horizontal axes restricting relative movement to rotation about said axes; whereby a user may perform a cycling routine while in a standing position.
Claim 3
Dependent Claim
23 words
A foot engageable rotational assembly according to claim 1, wherein said rotatable members and said intermediate rotatable member together comprise a gear assembly.
Claim 4
Dependent Claim
85 words
A foot engageable rotational assembly according to claim 2, wherein each of said foot engaging members comprises a substantially flat top surface and sleeve openings spaced along a side surface to receive said connection members, and each of said connection members is a substantially L-shaped rod having a first and second leg, said first leg including means for rigid attachment to one of said rotatable members, and second leg including means for attachment with one degree of freedom to one of said foot engaging members.
