Abstract
Abstract An arrangement for securing a braided rope to the ski tow rope handle by passing the rope through a transverse hole in the handle, passing the rope around the periphery of the handle and then inserting a portion of the end of the rope into the braided rope so that it passes back through the transverse hole in the handle. The braided rope acts in the manner of the well known Chinese finger, in that the higher the stress placed on the rope, the tighter it grasps the end of the rope that is inserted into it to prevent its detachment from the handle. To insure that the braided rope always retains some grip on the portion of rope inserted into it and to provide protection for the hands of the skier, a rubber sleeve is placed over the rope directly adjacent to the handle. In order to prevent the rubber sleeve from being displaced, a length of heat shrinkable tubing is applied to the rubber tubing and extends beyond the tubing to overlap onto the braided rope itself. The inner surface of this heat shrinkable tubing is provided with a heat sensitive adhesive to increase its hold on the rubber sleeve and the braided rope.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
143 words
In a water ski tow rope having a handle that is gripped by the skier and at least one tow line attached to the handle and extending therefrom for securement to the boat which is towing the skier, said tow line being formed of a braided material that is one continuous braided tubular wall having a central hollow core and one end of the tow line is passed into the hollow core of the braided two line to form a loop on the end of the tow line for attachment to said handle; an elastic sleeve gripping said line directly adjacent to said handle and extending therefrom a distance along said rope to protect the skiers hands from chafing and means overlapping said sleeve and said line to secure said elastic sleeve to said line against displacement by water pressures developed during skiing.
Claim 2
Dependent Claim
143 words
In a water ski tow rope having a handle that is gripped by the skier and at least one tow line attached to the handle and extending therefrom for securement to the boat which is towing the skier, said tow line being formed of a braided material that is one continuous braided tubular wall having a central hollow core and one end of the tow line is passed into the hollow core of the braided two line to form a loop on the end of the tow line for attachment to said handle; an elastic sleeve gripping said line directly adjacent to said handle and extending therefrom a distance along said rope to protect the skiers hands from chafing and means overlapping said sleeve and said line to secure said elastic sleeve to said line against displacement by water pressures developed during skiing.
Claim 3
Dependent Claim
33 words
A water ski tow rope according to claim 1 wherein said securing means is a length of heat shrinkable tubing that is shrunk onto said elastic sleeve and the rope in overlapping relationship.
Claim 4
Dependent Claim
64 words
A water ski tow rope according to claim 2 including a heat sensitive adhesive coated on the interior surface of said heat shrinkable tubing so that it is activated by the heat that is applied to said tubing to shrink it to thereby create a strong bond between said heat shrinkable tubing and the elastic sleeve and rope with which it is in contact.
Claim 5
Dependent Claim
78 words
A water ski rope according to claim 1 wherein said securing means is a plastic tubing that encompasses the end of said elastic sleeve and a portion of the tow line adjacent to it so that said plastic tubing overlaps said elastic sleeve and a portion of the tow line; and including an adhesive between said plastic tubing and the elastic sleeve and the tow line with which it is in contact to form a tight bond therebetween.
Claim 6
Dependent Claim
174 words
A water ski tow rope according to claim 1 wherein said tow line passes through a transverse hole in the handle and then about the periphery of the handle with an extending end of the tow line passing back through the transverse hole in the handle and through the hollow core of the braided tow line so that the braided wall of the tow line encompasses the extending end of the same tow line whereby as increasing longitudinal tension is applied to the tow line the braided wall of the tow line contracts diametrically to increasingly tighten about the extending end of the line within said braided wall to prevent the escape of the extending end; said elastic sleeve gripping said braided tow line directly adjacent to the handle to prevent excess relaxation of the braided tow line and thereby prevent inadvertent displacement of said extending end from the interior of the braided tow line, said elastic sleeve also protecting the hands of the skier from chafing due to contact with the tow line.
Claim 7
Dependent Claim
34 words
A water ski tow rope according to claim 5 wherein said securing means is a length of heat shrinkable tubing that is shrunk onto said elastic sleeve and onto the rope in overlapping relationship.
Claim 8
Dependent Claim
64 words
A water ski tow rope according to claim 6 including a heat sensitive adhesive coated on the interior surface of said heat shrinkable tubing so that it is activated by the heat that is applied to said tubing to shrink it and thereby creates a strong bond between said heat shrinkable tubing and the elastic sleeve and rope with which it is in contact.
Claim 9
Dependent Claim
78 words
A water ski rope according to claim 5 wherein said securing means is a plastic tubing that encompasses the end of said elastic sleeve and a portion of the line extending from said sleeve so that said plastic tubing overlaps said elastic sleeve and a portion of the tow line; and including an adhesive between said plastic tubing and the elastic sleeve and the tow line with which it is in contact to form a tight bond therebetween.
