  • the apparatus of the present invention comprises a The present invention relates to an apparatus for reel 4 rotatably mOunted On a Central StaliOnary Shaft winding a water-ski rope used by a water skierbeing towed by a motor boat.
  • the present invention is concerned with an improved apparatus for winding a water-ski rope on a reel in a short period of time when the end of the rope is set free from the skil ers hands, thereby avoiding detrimental entanglement of the rope in the boats motor.
  • a water-ski rope used for pulling a water skier at high speed is fastened to the stern of the motorboat.
  • the rope can be reeled and unreeled in accordance with the skiers movement. While the skier is being pulled by the boat, the rope is under tension, raising no problem of possible entanglement of the rope in the propeller of the boats motor.
  • the problem arises when the rope becomes detached from the skiers hands, either'intentionally or accidentally. In such a situation, the free end of the rope is likely to sink in the water due to its weight, thereby creating a danger of becoming entangled in the propeller of the boats motor.
  • the water skier does not always start from the shoreline, but sometimes starts in the middle of the water away from the shore.
  • Another object of the present invention is to provide an apparatus capable of, winding up a water-ski rope onto a reel in a short period of time when the end of the rope is set free from the skiers hands.
  • FIG. 2 is a front view of the apparatus illustrated in FIG. 1, partially cut away;
  • FIG. 3 is a diagrammatic view showing the epicyclic gearing device incorporating the present invention.
  • 0 body has internal gear-like teeth 5 at its inside surface.
  • the internal teeth are meshed by planetary gears 7 which, in turn, are meshed with stationary gear 6 fixed to the stationary shaft 3.
  • the planetary gears 7 are caused .to travel around the stationary gear 6.
  • the ratio of reduction is controlled by providing an appropriate number of teeth in each gear.
  • three elements of planetary gears are employed.
  • the planetary gears 7 have their respective shafts 8 connected with the outside sidewall of a rotary drum 9, in which a coiled spring 10 is housed, thereby securing a cooperable connection between the planetary gears and the rotary drum.
  • the spring 10 has its inner terminating end attached to the stationary shaft by means of a pin 11 and has its outer terminating end attached to the inside circumferential wall 12 of the drum 9. The spring is attached in such a manner that it is placed under relaxation when the rope 15 is wound upon the reel 4 and is placed in compression when the rope unwinds from the reel 4.
  • the spring 10 returns from a compression condition to a normal non-stress or relaxed condition, thereby causing the rotary drum 9 to reverse its rotation.
  • the rotary drum 9 reverses its direction of rotation, the reel 4 is rotated in the winding up direction.
  • a rope support bar 13 extends from the legs 1 and guides the rope 15 with the aid of a ring 14 through which the rope is passed.
  • the length of rope 15 is dependent upon the particular spring 10 which is utilized.
  • the rope is long enough to leave a few meters of unwound portion at the end of the rope on the 'water surface. According to the present invention, the
  • An apparatus for unwinding and winding a waterski line comprising a stationary shaft, a reel adapted to contain a supply of line rotatably mounted on said shaft, a rotary drum mounted for rotation about said shaft, means for transferring the rotation of the reel to the drum, said transferring means comprising a stationary gear fixed to the stationary shaft, internal gear-like teeth provided on the reel, and planetary gears provid ing gear-meshing communication between said internal gear-like teeth and the stationary gear, said planetary gears being connected by shaft means to the rotary drum, a spring housed by said drum, said spring being attached to the stationary shaft and the drum such that upon unwinding the line from the reel, the spring is converted from a relaxed state to a compressed state and upon the winding of the line on the reel, the spring is returned to its relaxed state.
  • the spring is a coiled spring with its inner end being attached to the stationary shaft and its outer end attached to the rotary drum.
