Abstract: A physical exercise device providing a stepper like motion for a user may include a pair of foot pedals and a pair of arms for engagement by the user while seated on the seat of the physical exercise device. The pair of foot pedals and the pair of arms may be connected to a drive train which provides contralateral motion between the pair of arms and the pair of foot pedals. A pedal and arm lock mechanism may also be provided which prevents the pedals and arms to be moved in a lock state, while allowing movement of the pedals and the arms when in the unlock state. The physical exercise device may also include computational and data acquisition units for receiving a position signal and pedal force signals and recording the signals.

Abstract: A walker for enabling ambulatory movement of disabled individuals. A frame assembly has front and rear legs with wheels. The legs are pivotably connected via a hinge and a support linkage. The support linkage permits folding together of the legs in a storage condition of the walker, and permits the legs to be being angularly separated for a use condition. A seat assembly includes a seat bottom foldable between up and down positions. A seat back and a toilet seat are affixed to the frame with the seat bottom being pivotable. The seat bottom overlays the toilet seat when in the down position and exposes the toilet seat for use when in the up position. The frame assembly enables the seat assembly and the toilet seat to be in a generally parallel orientation when the walker is in the folded-up storage condition.

Abstract: A recumbent stepper system has a tubular frame, a left leg assembly, a right leg assembly and a resistance mechanism. The leg assemblies are supported by the frame for pivoting movement about a central pivot axis. The leg assemblies each include an upwardly extending pedal arm terminating in a pedal. A left belt is coupled to the pedal arm of the left leg assembly and engages a left one way clutch and a left pulley. A right belt is coupled to the pedal arm of the right leg assembly and engages a right one way clutch and a right pulley. The resistance mechanism directly engages the left and right one way clutches via a resistance mechanism belt.
