Patent ID: 8257123

Claim:
An improvement to direct quadrimanual forward-rowing devices which constrain one's arms and legs to move in tandem throughout the rowing motion in which the improvement facilitates semi-independent use of one's arms in rowing a direct quadrimanual forward-rowing device, wherein the improvement comprises: (a) a starboard side of device comprised of (b) a starboard side off-set pedal bar aligned inboard of (c) a starboard side pivotable vertical axis by means of which the starboard side off-set pedal bar pivots fore and aft in a substantially horizontal dimension, said starboard side off-set pedal bar being connected to (d) a starboard side yoke holding (e) a starboard side pivotable horizontal axis by means of which (f) a starboard side off-set oar pivots up and down in a substantially vertical dimension, and (g) a port side of device comprised of a mirror image alignment of the components just described as comprising the starboard side of device and in conjunction with the starboard side of device components the port side of device comprises the improvement claimed herein, whereby one can row from a recumbent position using direct arm-and-leg tandem production of the alternating power and recovery strokes in the fore and aft dimension but using one's arms independently of one's legs to move the oars up and down into appropriate positions for the alternating power and recovery strokes.
