Abstract
Abstract A combination twister and stepper device includes a stepper unit and a twister unit in combination with a common frame. The stepper unit has a pair of side by side steps, each of which is biased upwardly. The twister includes a turntable or disk on a pivotal mount. The stepper and twister are secured to a frame which includes a pair of pivotal poles. The stepper and twister may be used simultaneously while also using the poles or the stepper and twister may be selectively inactivated so that only one of the units is used.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
144 words
A combination exercise device comprising a twist exercise unit and a stepper unit; said twist exercise unit including a base member, and a disk rotatably mounted to and above said base member whereby a user may stand on said disk and perform a twisting exercise; said stepper unit including a support, a pair of steps mounted to said support, resistance means reacting against said steps to urge said steps upwardly whereby a user must overcome the force of said resistance means to sequentially move said steps downwardly in a stepping exercise; a pair of poles located at one end of said steps, each of said poles being pivotally mounted; and said twist exercise unit and said stepper unit and said poles being structurally united by being mounted to a common structural assembly; wherein said twist exercise unit is detachably mounted on said stepper unit.
Claim 2
Dependent Claim

Claim 6
Dependent Claim
38 words
The device of claim 4 wherein said inactivating means further comprises a lock member for being disposed under each of said steps to prevent downward movement of said steps and to maintain said steps in a horizontal orientation.
Claim 7
Dependent Claim
144 words
A combination exercise device comprising a twist exercise unit and a stepper unit; said twist exercise unit including a base member, and a disk rotatably mounted to and above said base member whereby a user may stand on said disk and perform a twisting exercise; said stepper unit including a support, a pair of steps mounted to said support, resistance means reacting against said steps to urge said steps upwardly whereby a user must overcome the force of said resistance means to sequentially move said steps downwardly in a stepping exercise; a pair of poles located at one end of said steps, each of said poles being pivotally mounted; and said twist exercise unit and said stepper unit and said poles being structurally united by being mounted to a common structural assembly; wherein said stepper unit is detachably mounted on said twist exercise device.
Claim 8
Dependent Claim
144 words
A combination exercise device comprising a twist exercise unit and a stepper unit; said twist exercise unit including a base member, and a disk rotatably mounted to and above said base member whereby a user may stand on said disk and perform a twisting exercise; said stepper unit including a support, a pair of steps mounted to said support, resistance means reacting against said steps to urge said steps upwardly whereby a user must overcome the force of said resistance means to sequentially move said steps downwardly in a stepping exercise; a pair of poles located at one end of said steps, each of said poles being pivotally mounted; and said twist exercise unit and said stepper unit and said poles being structurally united by being mounted to a common structural assembly; wherein said stepper unit is detachably mounted on said twist exercise device.
Claim 9
Dependent Claim
21 words
The device of claim 6 including inactivating means for selectively inactivating each of said twist exercise units and said stepper unit.
Claim 10
Dependent Claim
21 words
The device of claim 7 wherein said inactivating means includes said stepper unit being detachably mounted on said twist exercise unit.
Claim 11
Dependent Claim
20 words
The device of claim 8 wherein said inactivating means further includes a stop member for preventing rotation of said disk.
Claim 12
Dependent Claim
16 words
The device of claim 9 wherein said stepper unit includes a base mounted on said disk.
Claim 13
Dependent Claim
57 words
The device of claim 10 wherein said stop member comprises a movable post having a flat contact surface, said base of said stepper unit having a flat contact surface and said movable post being selectively movable so that its said flat contact surface contacts said contact surface of said base to prevent any rotation of said disk.
