Claims
- 1. In an exercise device having frame means, a drive cord capable of reciprocal motion during cycles of operation including a pulling segment in which the drive cord is unwound from a recoil mechanism in a first direction and a recovery segment in which the drive cord moves in the direction opposite said first direction and is rewound on said recoil mechanism said recoil mechanism being mounted on the frame means, the improvement comprising:
- a hollow container mounted on said frame;
- a supply of liquid held in said container,
- liquid rotating means rotatably mounted within said container at its center and spaced from the walls of said container to rotate said supply of liquid within said container in response to movement of said drive cord during said pulling segment, said container having an inner surface in contact with said liquid, said inner surface being shaped to allow free movement of the liquid thereby allowing said supply of liquid to continue to rotate within said container during said recovery segment to produce thereby a liquid flywheel moving within said container and thereby maintaining the rotation of the liquid rotating means during the recovery segment and
- translating means mounted on said frame means and operatively connected to said liquid rotating means for translating a reciprocating motion of said drive cord during each cycle of operation into a one-way rotation of said liquid rotating means in response to said pulling segment of said cycle of operation, said translating means being coupled to said drive cord and said recoil mechanism,
- said supply of liquid when rotating producing resistance to said pulling segments due principally to turbulence at the liquid-container interface, and
- said liquid rotating means being capable of rotating in unison with said rotating liquid during said pulling and recovery strokes.
- 2. The improved exercise device of claim 1 wherein said container is closed.
- 3. The improved exercise device of claim 1 wherein said supply of liquid fills less than half of the interior volume of said container.
