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.

1. An adjustable resistance exercise device comprising

a 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;

2. The adjustable resistance exercise device of claim 1 wherein the housing includes a handle engaging region.

3. The adjustable resistance exercise device of claim 1 further including at least one pulley rotatably mounted to the frame and receiving the cable from the cable receiving spool, wherein an axis of rotation of the pulley is generally orthogonal to an axis of rotation of the cable receiving spool.

at least one resistance wheel rotatably coupled to the support frame and selectively engaged with the cable receiving spool such that the cable receiving spool and the resistance wheel are engaged when the cable receiving spool rotates in the unwinding direction and the cable receiving spool and the resistance wheel are disengaged when the cable receiving spool rotates in the winding direction; and

at least one rotation resistance member engaging the resistance wheel to resist rotation of the resistance wheel.

5. The adjustable resistance exercise device of claim 4 wherein the adjustable resistance and retraction mechanism further comprises:

a locking cam gear mechanism coupled between the resistance wheel and the cable receiving spool such that the cable receiving spool and the resistance wheel are engaged when the cable receiving spool rotates in the unwinding direction and the cable receiving spool and the resistance wheel are disengaged when the cable receiving spool rotates in the winding direction.

6. The adjustable resistance exercise device of claim 4 wherein the rotation resistance member includes a rotation resistance belt wrapped around at least a portion of the resistance wheel.

7. The adjustable resistance exercise device of claim 6 wherein the adjustable resistance and retraction mechanism further includes a tension adjustment member coupled to the rotation resistance belt for adjusting tension of the rotation resistance belt to adjust the resistance applied to the resistance wheel and the tension on the cable.

8. The adjustable resistance exercise device of claim 1 wherein the adjustable resistance and retraction mechanism includes a spring engaging the cable receiving spool to apply the retraction force, wherein the spring is loaded when the cable receiving spool is rotated in the unwinding direction by the cable moving toward the extended position.

9. The adjustable resistance exercise device of claim 1 further comprising at least one handle coupled to the cable.

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;
