Abstract
A rotatable spool includes a frame with a central rod and a hollow cylinder that is rotatable about the central rod. The cylinder includes an inscribed helical thread that is formed along the length of the cylinder and a central axis parallel with the central rod. The operator is disposed around a portion of the cylinder and includes a projection engaged with the helical thread such that linear movement of the operator causes the cylinder to rotate about its central axis. A reel is rotatably mounted on the frame and a clutch selectively couples the cylinder and the reel when the operator is depressed toward the frame.
Claims25
A rotatable spool comprising:
- (a) a frame with a central rod;
- (b) a hollow cylinder rotatable about the central rod, comprising a helical thread formed along the cylinder and a central axis parallel with the central rod;
- (c) an operator disposed around a portion of the cylinder, comprising a projection that is engaged with the helical thread such that linear movement of the operator causes the cylinder to rotate about its central axis;
- (d) a reel rotatably mounted on the frame;
- and
- (e) a clutch selectively coupling the cylinder and the reel when the operator is depressed.
A rotatable spool comprising:
- (a) a rotatable cylinder comprising a helical groove inscribed on an outer surface of the cylinder;
- (b) an operator at least partially surrounding the cylinder, the operator comprising a projection that engages the helical groove;
- (c) a bracket surrounding a portion of the operator and the cylinder;
- (d) a clutch selectively engaging the cylinder and the bracket;
- and
- (d) a reel removeably engageable with the bracket for rotation with the bracket.
A rotatable spool comprising:
- (a) a rotatable cylinder comprising a helical thread inscribed on an outer surface of the cylinder;
- (b) an operator disposed concentrically and at least partially surrounding the cylinder, the cylinder comprising a top end, a bottom end, and a projection radially extending toward the rotational axis provided in the vicinity of the bottom end of the operator;
- (c) a reel rotatably mounted at least partially surrounding the cylinder and the operator and engageable with the cylinder to rotate therewith.
