摘要： A positioning reel (10) for suspending a body (17), such as a lightweight tool, at any vertical position within the limits of the suspension cord (18) length is disclosed. An adjusting screw (38) which regulates a clutch-type tensioning brake (22, 30, 32) permits the supporting force of the positioning reel to be set to equalize the weight of the suspensed body such that little effort is required to lower the suspended body. With the downward external positioning force removed from the suspended body, it remains in its present position. The suspended body can be easily raised by applying an upward external force equal to slightly more than the weight of the suspended body. When raising the suspended body, a clock-type coil spring (24) actuates a spool (22) within the positioning reel for retracting the suspension cord. A spring-type override clutch (22A, 62) permits reeling in the suspension cord while bypassing the tensioning brake. With the upward external force removed from the suspended body, it will again remain in its present position.
