Abstract:
1. A drive mechanism for effecting a rotary power output in a selected one of opposite first and second power output directions in response to a reciprocating power input resulting from essentially same-directed substantially linear forces applied to the drive mechanism, the drive mechanism comprising: a first input drive arrangement mounted for rotation in each one of opposite first and second input directions of rotation about a first input axis of rotation, the first input drive arrangement being rotatable in the first input direction of rotation in response to a first substantially linear force applied to the first input drive arrangement; a second input drive arrangement mounted for rotation in each one of opposite first and second input directions of rotation about a second input axis of rotation, the second input drive arrangement being rotatable in the first input direction of rotation in response to a second substantially linear force applied to the second input drive arrangement; a first output drive arrangement mounted for rotation about a first output axis of rotation, the first output drive arrangement being coupled with the first input drive arrangement for rotation of the first output drive arrangement in a first output direction of rotation in response to rotation of the first input drive arrangement in the first input direction of rotation, and being coupled with the second input drive arrangement for rotation of the first output drive arrangement about the first output axis of rotation in a second output direction of rotation, opposite to the first output direction of rotation, in response rotation of the second input drive arrangement in the first input direction of rotation; a second output drive arrangement mounted for rotation about a second output axis of rotation, the second output drive arrangement being coupled with the second input drive arrangement for rotation of the second output drive arrangement about the second output axis of rotation in the first output direction of rotation in response to rotation of the second input drive arrangement in the first input direction of rotation, and being coupled with the first input drive arrangement for rotation of the second output drive arrangement about the second output axis of rotation in the second output direction of rotation, opposite to the first output direction of rotation, in response to rotation of the first input drive arrangement in the first input direction of rotation; a power output shaft mounted for rotation in either one of the first and second power output directions about a power output axis of rotation; a clutch arrangement for actuation between a first condition wherein the first output drive arrangement is coupled with the power output shaft for effecting rotation of the power output shaft in the first power output direction in response to rotation of the first input drive arrangement in the first input direction of rotation, while enabling rotation of the first input drive arrangement in the second input direction of rotation independent of rotation of the power output shaft, and the second output drive arrangement is coupled with the power output shaft for effecting rotation of the power output shaft in the first power output direction in response to rotation of the second input drive arrangement in the first direction of rotation, while enabling rotation of the second input drive arrangement in the second input direction of rotation independent of rotation of the power output shaft, and a second condition wherein the second output drive arrangement is coupled with the power output shaft for effecting rotation of the power output shaft in the second power output direction in response to rotation of the first input drive arrangement in the first input direction of rotation, while enabling rotation of the first input drive arrangement in the second input direction of rotation independent of rotation of the power output shaft, and the first output drive arrangement is coupled with the power output shaft for effecting rotation of the power output shaft in the second power output direction in response to rotation of the second input drive arrangement in the first input direction of rotation, while enabling rotation of the second input drive arrangement in the second input direction of rotation independent of rotation of the power output shaft; and a selector mechanism coupled with the clutch arrangement for actuating the clutch arrangement selectively into one of the first and second conditions; whereby the first and second substantially linear forces applied to the drive mechanism in the same manner enable a rotary power output in either selected one of the first and second power output directions at the power output shaft.
