Abstract

A towrope retriever system for a watercraft for simplifying and improving the safety of the towrope handling, storage, reeling out, and reeling in of a towrope, in which the towrope retriever is connected to or integrated into a support unit such as a tower or pylon securely attached to the watercraft, substantially increasing the overall height of the watercraft, and allowing the performer to jump higher and perform more challenging aerial maneuvers, is disclosed. The towrope retriever may be rotatable to allow the performer a greater flexibility of movement and may be easily removed for storage.

Claims

1. A towrope retriever system for a watercraft, comprising:

(a) a support unit securely attached to the watercraft for substantially increasing overall height of the watercraft and for increasing acrobatic characteristics of water sport activities by a performer;

(b) a towrope retriever comprising;

i) a main housing unit connected to the support unit;

ii) an electronic control unit;

iii) a reel being axially mounted on said main unit and for reeling a towrope having an attachment end attached to said reel and a handle end, said reel being axially mounted in the main housing, and said towrope;

iv) a motor operatively connected to the reel and electrically controlled by the electronic control unit for providing rotational power to the reel; and

v) a rope holding device for securely holding the towrope at a selected length.

2. The towrope retriever system of claim 1, wherein the reel is concentrically mounted on the motor.

3. The towrope retriever system of claim 1, wherein the support unit is a pylon being rigidly attached to the watercraft.

4. The towrope retriever system of claim 1, wherein said watercraft further includes:

(a) a bow,

(b) a stern, and

(c) a starboard gunwale and a port side gunwale located between the bow and the stern,

wherein the support unit is a tower being rigidly attached to the starboard gunwale and the port side gunwale.

5. The towrope retriever system of claim 1, wherein the motor is powered by electrical power supplied from a power supply on the watercraft.

6. The towrope retriever of claim 1, wherein the motor is capable of forward and reverse operation.

7. The towrope retriever system of claim 1, wherein the motor is adapted to provide reverse torque to hold the towrope in position.

8. The towrope retriever system of claim 1, wherein the motor is capable of variable speed operation.

9. The towrope retriever system of claim 1, wherein the motor is capable of unidirectional operation.

10.he. The towrope retriever system of claim 1, wherein the motor is capable of fixed speed operation.

11.he. The towrope retriever system of claim 1 wherein the electronic control unit includes an electric speed switch to adjust rotational speed of the motor.

12.he. The towrope retriever system of claim 1 wherein the electronic control unit includes an electric direction switch to adjust rotational direction of the motor.

13.he. The towrope retriever system of claim 1, wherein the main housing unit further includes a split collar for rotatably connecting the towrope retriever to a knob on the watercraft.

15.he. The towrope retriever system of claim 1 further comprising one or more visual length indicators placed on the towrope.

17.he. The towrope retriever system of claim 1, wherein the electronic control unit is a wireless handheld device.

18.he. The towrope retriever of claim 1, wherein the electronic control unit is an integrated wired device.

19.he. The towrope retriever system of claim 2 further comprising:

(a) a safety clutch having an input side and an output side, said safety clutch being configured to be driven by the motor on said input side;

(b) a motor-to-spool drive housing being engageably connected to the safety clutch at the output side thereof and fixedly mounted onto the reel for transmitting torque from the motor to the reel; and

(c) a ratchet pawl assembly being configured to prevent motion of the reel in a reel-out direction.

27.he. The towrope retriever system of claim 1, wherein the towrope retriever is encased in a main housing.

14.he. The towrope retriever system of claim 13 further comprising a quick release mechanism allowing easy removal of the towrope retriever from the knob.

16. The towrope retriever system of claim 15 wherein the main housing further comprises a measurement reference point for measuring length of the towrope from said measurement reference point to the handle end.

20.he. The towrope retriever system of claim 19, wherein said ratchet pawl assembly comprises:

(a) a solenoid,

(b) a pawl catch,

(c) a ratchet pawl,

(d) a trip lever, and

(e) a pawl spring;

such that said ratchet pawl assembly prevents motion of the reel by engagement of said pawl with said ratchet wheel, whereupon the reel being driven by the motor in a reel-in direction, said ratchet moves said trip lever into engagement with said pawl catch and holds said ratchet pawl out of engagement with said ratchet wheel, thereby allowing free rotation of the reel.

21.he. The towrope retriever system of claim 20, wherein the safety clutch is adapted to slip when torque from the concentric motor or the concentric spool exceeds a predetermined torque setting.

22.he. The towrope retriever system of claim 21, wherein the electronic control unit includes an electric release switch to release the solenoid, thereby allowing the towrope to be reeled out when pull on said towrope exceeds a predetermined clutch setting.

23.he. The towrope retriever system of claim 21, wherein the electronic control unit includes an electric reel-in switch to activate the motor in a reel-in direction to disengage said ratchet pawl.

24.he. The towrope retriever system of claim 21, wherein the electronic control unit includes an electric lock switch to activate said solenoid to release said ratchet pawl, such that the ratchet pawl engages and locks the reel.

25.he. The towrope retriever system of claim 21, wherein the electronic control unit includes an automatic towrope length adjuster.

26.he. The towrope retriever system of claim 21 further comprising a towrope length measuring device for measuring a length of the towrope being reeled out.

28.he. The towrope retriever system of claim 27, wherein the main housing is integrated into the support unit.
