Abstract:
1. A rowing machine comprising: a frame consisting of a first tubular member and a second tubular member wherein said first and second tubular member are disposed in parallel relationship and a first cross member attached to said first and said second tubular members and a second cross member attached to said first and second tubular members; a foot rest assembly including a third tubular member, a fourth tubular member and a third cross member attached near a distal end of said third and fourth tubular members, said third and fourth tubular members separated by a distance corresponding to the displacement between said first and second tubular members and wherein said third and fourth tubular members are slidably inserted within said first and second tubular members, respectively; a first swivel arm pivotally attached to said first cross member at a location near said first tubular member, said first swivel arm being pivotally positionable between a first angular position substantially parallel to said first tubular member and a second angular position substantially away from said first tubular member; a first resistance means having a first shaft and a second shaft, and wherein said first shaft is attached to the distal end of said first swivel arm, said first resistance means providing rotational resistance between said first shaft and said second shaft in only one rotational direction; a first oar arm attached to said second shaft of said first resistance means; a second swivel arm pivotally attached to said first cross member at a location near said second tubular member, said second swivel arm being pivotally positionable between a first angular position substantially parallel to said second tubular member and a second angular position substantially away from said second tubular member; a second resistance means having a third shaft and a fourth shaft, and wherein said third shaft is attached to the distal end of said second swivel arm, said second resistance means providing rotational resistance in only one rotational direction between said third shaft and said fourth shaft; a second oar arm attached to said fourth shaft of said first resistance means; and a seat including spaced apart rollers rotatably attached to the underside of said seat, and wherein said seat is situated over said first and second tubular members and said rollers engage said tubular members.
