1. An adjustable resistance exercise device comprisinga support frame;
- at least one cable receiving spool rotatably coupled to the support frame;
at least one cable coupled to the cable receiving spool, wherein a length of the cable is coiled around the cable receiving spool in a retracted position and wherein the length of the cable extends from the cable receiving spool in an extended position, wherein the cable receiving spool is rotatable in a winding direction when the cable is being retracted toward the retracted position, and wherein the cable receiving spool is rotatable in an unwinding direction when the cable is being extended toward the extended position;
at least one adjustable resistance and retraction mechanism operably coupled to the cable receiving spool to apply an adjustable resistance force to the cable receiving spool and to apply a retraction force to the cable receiving spool independent of the adjustable resistance force, wherein the resistance force resists rotation of the cable receiving spool in the unwinding direction to resist extension of the cable toward the extended position when the cable receiving spool is rotating in the unwinding direction, wherein the resistance force is applied only when the cable receiving spool is rotating in the unwinding direction, and wherein the retraction force causes the cable receiving spool to rotate in the winding direction to retract the cable toward the retracted position when the cable receiving spool is rotating in the winding direction; and
a housing including a top surface for receiving part of a user, wherein the housing houses the frame, the cable receiving spool, and the adjustable resistance and retraction mechanism, wherein the housing includes an aperture that receives the cable and allows the cable to extend and retract, and wherein the at least one cable receiving spool lies substantially parallel to the top surface of the housing such that an axis of rotation of the cable receiving spool is substantially perpendicular to the top surface of the housing.

Abstract
A resistance exercise device enables resistance training by using one or more retractable cables that provide resistance to the user when the user pulls on the cable(s). The resistance exercise device provides a retraction force to retract the cable(s), which is independent of a resistance force applied to the cable(s). The resistance exercise device may thus allow adjustment of the resistance force without affecting the retraction force.

10. A resistance exercise device comprising
a support frame; -
at least one resistance wheel rotatably coupled to the support frame; at least one cable receiving spool rotatably coupled to the support frame and selectively engaged with the resistance wheel such that rotation of the cable receiving spool in an unwinding direction causes the resistance wheel to rotate and rotation of the cable receiving spool in a winding direction is independent of the resistance wheel; at least one cable coupled to the cable receiving spool, wherein a length of the cable is coiled around the cable receiving spool in a retracted position and wherein the length of the cable extends from the cable receiving spool in an extended position; at least one resistance member engaging the resistance wheel to resist rotation of the resistance wheel in the unwinding direction such that the cable resists extension toward the extended position; and at least one retraction spring engaging the cable receiving spool to cause the cable receiving spool to rotate in the winding direction such that the cable retracts toward the retracted position; and a housing including a top surface for receiving part of a user, wherein the housing houses the frame, the resistance wheel, the cable receiving spool, the resistance member, and the retraction spring, wherein the housing includes an aperture that receives the cable and allows the cable to extend and retract, and wherein the at least one cable receiving spool substantially parallel to the top surface of the housing such that an axis of rotation of the cable receiving spool is substantially perpendicular to the top surface of the housing. - View Dependent Claims (11, 12, 13, 14)
