Patent ID: 7604576

Claim:
An exercise apparatus, comprising: (a) at least one frame; (b) at least one translating force transmitter movably connected to the frame; (c) at least one spooling force transmitter having a spool rim and rotational axis, the spooling force transmitter movably connected to the frame; (d) at least one resistance source; (e) a flexible connector, the flexible connector connected to the resistance source and to both the spooling force transmitter, and, the translating force transmitter; (f) at least one carriage mounted on the frame and supporting the spooling force transmitter such that the spooling force transmitter can pivot on its rotational axis, the carriage further supporting the spooling force transmitter to revolve around a positioning axis that is substantially coincident with the flexible connector's longitudinal axis as it passes through the carriage, the rotational axis being offset from the positioning axis such that the axes do not intersect; and (g) at least one rigid arm connected to at least one of the following elements of the apparatus: 1) the spooling force transmitter, and, 2) the translating force transmitter, the arm adapted to receive an exercise force generated by a user, the resistance force and the exercise force placing opposing forces on the force transmitter to which it is connected.
