Abstract

A scuba diving reel comprising a hand held frame rotatably mounting a line receiving spool on which a length of line is wound. A coupling member is provided on the terminal end of the line for attaching the line to an object such as a buoy so that when the scuba diver moves away from the buoy, the spool will rotate and pay out line. Anti-backlash mechanism is provided for preventing the freewheeling of the spool when tension force thereon is removed. Rotatable pinch mechanism is provided for maintaining taut the line portion between the pinch mechanism and the spool.

Claims

1. A hand held portable reel for scuba diving or the like comprising:

a frame;

a spool rotatably mounted on said frame;

a length of line wound about said spool and having a terminal end for attaching to an object, such as a floating buoy, so that as said reel and said object are relatively moved away from each other, the line will become taut to force said reel to rotate in one direction and allow line wound on the reel to be payed out;

anti-backlash means on said frame for preventing free wheeling of said spool when line is not being payed out;

means for driving said spool in a direction opposite said one direction for winding said line on said spool;

line tensioning means on said frame for yieldably receiving, pinching and passing said line to maintain the portion of said line between said tensioning means and said spool taut when said spool is driven in said opposite direction but yieldable so as to allow the line to be payed out; and

brake means on said frame for releasably locking said spool to inhibit rotation thereof when the reel is not in use;

said line tensioning means comprising

a pair of rollers rotatably mounted on said frame for squeezing opposite sides of said line and

endless resilient means bearing against and reacting between said rollers for restricting the free rotation of said rollers.

2. The reel set forth in claim 1 wherein brake means is provided on said frame for releasably locking said spool to inhibit rotation thereof when the reel is not in use.

3. The reel set forth in claim 1 wherein said frame includes an aperture through which said length of line passes;

said pair of rollers being disposed in said aperture.

4. The reel set forth in claim 1 including means mounting said rollers on said frame such that the distance between the confronting surfaces thereof is less than the diameter of said line.

5. A hand held portable reelf or scuba diving or the like comprising:

a frame;

a spool rotatably mounted on said frame;

a length of line of predetermined diameter wound about said spool and having a terminal end for attaching to an object, such as a floating buoy, so that as said reel and said object are relatively moved away from each other, the line will become taut to force said reel to rotate in one direction and allow line wound on the reel to be payed out;

anti-backlash means on said frame for preventing free wheeling of said spool when line is not being payed out;

means for driving said spool in a direction opposite said one direction for winding said line on said spool;

line tensioning means on said frame for yieldably receiving, pinching and passing said line to maintain the portion of said line between said tensioning means and said spool taut when said spool is driven in said opposite direction but yieldable so as to allow the line to be payed out;

said line tensioning means comprising

a pair of rollers rotatably mounted on said frame including annular surfaces for squeezing opposite sides of said line; and

yieldable means reacting between said rollers and bearing against said annular surfaces for restricting the free rotation of said rollers.

6. The reel set forth in claim 5 wherein said yieldable means comprises resilient means abutting said annular surfaces.

7. The reel set forth in claim 6 wherein at least a portion of said resilient means is disposed between said rollers.

8. The reel set forth in claim 6 wherein said frame includes an aperture and said rollers are disposed in said aperture.

9. The reel set forth in claim 8 further including clamp means for detachably clamping said spool to said frame including means reacting between the opposite end of said shaft and said frame.

10. The reel set forth in claim 9 wherein said clamp means comprises a screw threadedly received in said opposite end of said shaft and mount means mounting said screw for rotation about its axis between a locked position in which said mount means and said spool are tightly sandwiched against opposite side of a portion of said frame to preclude rotation of said spool and an unlocked position.

11. The reel set forth in claim 10 wherein said clamp means including means reacting between said shaft and said frame to inwardly deflect portions of said frame on opposite sides of said spool into clamping engagement with said spool.

12. The reel set forth in claim 9 wherein said frame includes opposing side portions;

said spool is journaled for rotation between said opposing side portions of said frame;

said clamp means comprises a screw threadedly received in said opposite end of said shaft and mount means mounting said screw for rotation about its axis between a locked position, in which said spool is tightly sandwiched between said opposing side portions of said frame, to preclude rotation of said spool, and an unlocked position.

13. The reel set forth in claim 12 wherein said clamp means includes means reacting between said shaft and portions of said frame on opposite sides of said spool to inwardly deflect said frame portions into clamping engagement with said spool.

14. The reel set forth in claim 5 wherein said frame comprises a U-shaped member having a pair of legs and a base member spanning said legs;

a hand grippable handle mounted on said base.

15. The reel set forth in claim 14 wherein said spool includes a shaft journaled on said pair of legs and a hub mounted on said shaft for rotation therewith;

and

including brake means for releasably locking said spool to inhibit rotation thereof when the reel is not is use comprising clamp means mounted on said frame for movement between an unclamping position and a clamping position in which said spool is clamped to said frame.

16. The reel set forth in claim 15 wherein said clamp means comprises screw means, threadedly received by an outer terminal end of said shaft, rotatable about its axis;

and mount means mounting said screw means for movement between an axially outer unlocked position removed from said frame and an axially inward locked position in which said mount means abuts and bears against said frame.

17. The reel set foth in claim 15 further including handle means fixed to the opposite end of said shaft for rotating said spool about its axis to wind said line on said spool.

18. The reel set forth in claim 17 wherein said frame includes a second U-shaped member mounted on said first mentioned U-shaped member and including a pair of legs, spanned by a second base member, coupled to said first mentioned pair of legs;

said aperture being provided in said second base member.
