Abstract
The present invention relates to the field of pull/push exercise with an exercise machine that exercises the abdominal, back and arm muscles with the operator recumbent in the face upwards position. Foot contacts follow a closed elongate curve positioned above the recumbent operator. A linkage is provided for each foot contact in conjunction with a crank to drive a flywheel. Arm exercise is coordinated with the linkage.
Claims27
An exercise machine for allowing a recumbent operator to move the feet through a closed elongate curve comprising;
- a framework, said framework configured to be supported by a generally horizontal surface;
- a crank rotatably connected to said framework at a crank bearing housing, said crank projecting outwardly therefrom on both sides thereof;
- a pair of foot engaging members, each said foot engaging member pivotally connected to said crank;
- a pair of guides, each said guide connected to corresponding said foot engaging member at a guide pivot, wherein said guide pivot has back and forth movement;
- a pair of foot contacts, each said foot contact pivotally connected to corresponding said foot engaging member proximate one end of said foot engaging member;
- said foot contact configured to move relative to said framework when the foot of said recumbent operator is rotating said crank whereby said foot contact follows said closed elongate curve with the hip of said recumbent operator positioned below said crank bearing housing.
An exercise machine for allowing a recumbent operator to move the feet through a closed elongate curve comprising;
- a framework, said framework configured to be supported by a generally horizontal surface;
- a crank rotatably connected to said framework, said crank projecting outwardly therefrom on both sides thereof;
- a pair of foot engaging members, each said foot engaging member pivotally connected to said crank intermediate the ends of said foot engaging member;
- a pair of guides, each said guide connected to corresponding said foot engaging member at a guide pivot positioned at one end of said foot engaging member, wherein said guide pivot has back and forth movement;
- a pair of foot contacts, each said foot contact pivotally connected to corresponding said foot engaging member proximate the other end of said foot engaging member;
- said foot contact configured to move relative to said framework when the foot of said recumbent operator is rotating said crank whereby said foot contact follows said closed elongate curve with the hip of said recumbent operator positioned below complete path of said closed elongate curve.
An exercise machine for allowing a recumbent operator to move the feet through a closed elongate curve comprising;
- a framework, said framework configured to be supported by a generally horizontal surface;
- a crank rotatably connected to said framework, said crank projecting outwardly therefrom on both sides thereof;
- a pair of foot engaging members, each said foot engaging member pivotally connected to said crank intermediate the ends of said foot engaging member;
- a pair of guides, each said guide connected to corresponding said foot engaging member at a guide pivot positioned at one end of said foot engaging member, wherein said guide pivot has back and forth movement;
- a pair of foot contacts, each said foot contact pivotally connected to corresponding said foot engaging member proximate the other end of said foot engaging member and said foot contact configured to receive force from the upper portion of the foot of the operator;
- said foot contact configured to move relative to said framework when the foot of said recumbent operator is rotating said crank whereby said foot contact follows said closed elongate curve with the hip of said recumbent operator position below the complete path of said closed elongated curve with the hip of saiid recumbent operator positioned below the complete path of said closed elontgate curve.
