Adjustable pull-rope exercise device
First Claim
1. Exercise apparatus of the type that includes a housing with at least one rope guide, a rope that extends through said at least one rope guide and that has rope portions on opposite sides of said at least one rope guide, a pair of handles that are each coupled to a different one of said rope portions and that each has a grip that can be grasped by fingers of a hand to pull said different rope portions, and a mechanism that is manually operable to enable lengthening or shortening of said rope portions, comprising:
- at least one windup spool coupled to said rope, and a spring device that urges said spool to turn to windup rope thereon and that allows said spool to turn to unwind rope therefrom, to respectively shorten and lengthen at least one of said rope portions, but only when said spool is released to wind up rope;
a manually operable release mechanism that normally prevents rotation of said spool and that is operable by a person while that person grasps said grips of said handles, to release said spool to windup or unwind rope;
said release mechanism being capable of being not operated to not release said spool and being capable of being operated to release said spool, all while a person grasps said grips of said handles and pulls the handle away from said at least one rope guide to lengthen a rope portion or allows the handle to move toward said at least one rope guide to shorten a rope portion.

Abstract
A compact exercise device (10) of the type wherein a person grips handle devices (12, 30) lying at opposite ends of a rope that extends through a housing (22), the person pulling one end of the rope away from the housing while resisting movement of the other end of the rope towards the housing to exercise. A windup spool (114) lies in one of the handle devices and a spring (130) urges the spool to wind up rope by a spring, but the spool is normally prevented from turning in either direction by a release mechanism (110). A person who holds a handle grip (100) with most fingers of his/her hand, uses his/her thumb to depress a button (90) to operate the release mechanism. While the thumb continues to depress the button, the person moves a handle device away from the housing to lengthen the effective length of rope, or moves a handle device towards the housing to shorten the effective length of rope. In another device, windup spools (226, 228) lie in the housing, and a person depresses a button (202) on the housing to operate the release mechanism.
