Exercise device

Claim 2

An exercise device comprising: a driving sprocket having a first axis of rotation; means for rotating said sprocket about the first axis; means having a second axis of rotation for supporting said sprocket about said first axis in a first position where said sprocket is adapted to be rotated by foot, and for rotating said sprocket about said second axis to a second position where said sprocket is adapted to be rotated by hand; and a seat having an elevation level and operative to support an exercise device operator, wherein the elevation level of said first axis when said sprocket in said first position is lower than the elevation level of said seat, and said elevation level of said first axis when said sprocket is in said second position is higher than the elevation level of said seat, the seat and the sprocket being dimensioned so that the operator can reach the sprocket with the operator's feet in the first position and the operator's hands in the second position, both while on the seat.

Claim 3

The exercise device as recited in claim 2 further comprising means for resisting the rotation of said sprocket about said first axis.

Claim 4

The exercise device as recited in claim 1 further comprising: means for restricting the direction of rotation of said sprocket to a first direction; and means for changing the direction of rotation of said sprocket is restricted from the first direction to a second direction opposite from said direction.

Claim 5

An exercise device comprising: a longitudinally extending frame; a driving sprocket disposed adjacent one end of said frame having a first lateral axis exiting through the frame, said lateral axis being the axis of rotation of said sprocket; a driven wheel disposed adjacent the other end of said frame from said sprocket and having a second lateral axis extending through the frame, said driven wheel rotating about said axis; a pedal coupled to said sprocket operative to rotate said sprocket; a chain connected between said driving sprocket and said driven wheel for rotating said wheel when said sprocket is rotated; a support frame adapted to resting on a wall or floor surface, said support frame having pivot means connected to said longitudinal frame between said driving sprocket and said driven wheel for permitting said sprocket to rotate about said second longitudinal axis at least 180°; a seat coupled to said support frame adapted to support an operator in a sitting position; and means for permitting the horizontal level of said pedals to be adjusted where said operator can contact said pedals with the foot while sitting on said seat when said pedals are in a first position and where said operator can contact said pedals with the hand while sitting on the seat when said pedals are in a second position, said pedal first position having a horizontal level lower than the seat level and said pedal second position having a horizontal level higher than the seat level.

Claim 6

An exercise device comprising: a longitudinally extending frame; a driving sprocket disposed adjacent one end of said frame having a first lateral axis exiting through the frame, said lateral axis being the axis of rotation of said sprocket; a driven wheel disposed adjacent the other end of said frame from said sprocket and having a second lateral axis extending through the frame, said driven wheel rotating about said axis; a pedal coupled to said sprocket operative to rotate said sprocket; a chain connected between said driving sprocket and said driven wheel for rotating said wheel when said sprocket is rotated; a support frame adapted to resting on a wall or floor surface, said support frame having pivot means connected to said longitudinal frame between said driving sprocket and said driven wheel for permitting said sprocket to rotate about said second longitudinal axis at least 180°; a seat coupled to said support frame adapted to support an operator in a sitting position; and means for permitting the horizontal level of said pedals to be adjusted where said operator can contact said pedals with the foot while sitting on said seat when said pedals are in a first position and where said operator can contact said pedals with the hand while sitting on the seat when said pedals are in a second position, said pedal first position having a horizontal level lower than the seat level and said pedal second position having a horizontal level higher than the seat level.

Claim 7

The exercise device as recited in claim 4 further comprising a support arm connected between said support frame and said longitudinal frame for holding said longitudinal frame in a fixed position relative to said support frame when said sprocket is rotated.

Claim 8

The exercise device as recited in claim 5 wherein said support are further comprising means for adjusting the position of said longitudinally extending frame to said support frame.

Claim 9

The exercise device as recited in claim 4 further comprising means for resisting the rotation of said driven wheel about said first axis.

Claim 10

The exercise device as recited in claim 4 wherein said support frame has a generally U-shaped configuration.

Claim 11

The exercise assembly recited in claim 4 further comprising a reversible ratchet on the exercise unit for controlling resistance in either direction of rotation of the drive sprocket.
