Abstract
Abstract An elastic tie-down comprises as inelastic rope having enlargements thereon that are captured by an elastic sleeve. The elastic sleeve is shorter than the spacing between the rope enlargements. Pulling the rope ends causes the rope enlargements to bear against the sleeve ends and stretch the sleeve. The rope ends are provided with hooks. The length between the hooks is adjustable without affecting the elastic properties of the tie-down by a clip that slidably receives the standing end of one of the rope ends extending from the sleeve. The clip also secures the rope end, thereby creating an adjustable sized loop in the rope. A hook is slidably received over the rope in the loop. Sliding the clip along the rope standing end varies the size of the loop and thereby alters the length between the two hooks independently of the tension in the elastic sleeve.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
155 words
A tie-down comprising: a. a flexible rope having first and second ends and a pair of spaced abutment means on the rope between the two ends; and b. an elastic sleeve placed over the rope intermediate the rope ends, and encapsulating and concealing said abutment means enlargements, the sleeve length being less than the spacing between the rope abutment means to create a rope slack inside the sleeve, the sleeve being crimped tightly at the ends thereof over the rope to grip the rope and capture said abutment means and rope slack between the sleeve ends and to create rope first and second ends extending oppositely from the ends of the sleeve and having sufficient length to afford connection of said rope ends for rope usage, so that applying tension to the rope ends causes said abutment means to cause tension on said elastic sleeve to stretch and thereby impart elastic qualities to the tie-down.
Claim 2
Dependent Claim
155 words
A tie-down comprising: a. a flexible rope having first and second ends and a pair of spaced abutment means on the rope between the two ends; and b. an elastic sleeve placed over the rope intermediate the rope ends, and encapsulating and concealing said abutment means enlargements, the sleeve length being less than the spacing between the rope abutment means to create a rope slack inside the sleeve, the sleeve being crimped tightly at the ends thereof over the rope to grip the rope and capture said abutment means and rope slack between the sleeve ends and to create rope first and second ends extending oppositely from the ends of the sleeve and having sufficient length to afford connection of said rope ends for rope usage, so that applying tension to the rope ends causes said abutment means to cause tension on said elastic sleeve to stretch and thereby impart elastic qualities to the tie-down.
Claim 3
Dependent Claim
23 words
The tie-down of claim 1 wherein said abutment means is dimensioned to prevent said rope from being pulled through said sleeve crimped opening.
Claim 4
Dependent Claim
16 words
The tie-down of claim 2 wherein said abutment means are not fixedly connected to said sleeve.
Claim 5
Dependent Claim
100 words
The tie-down of claim 1 further comprising a clip having a longitudinally extending flat surface for adjusting the length between the two rope ends independently of the tension produced in the elastic sleeve, the clip having first and second holes with substantially parallel axes through the flat surface, the rope second end being fastened to the clip at the second clip hole, the first clip hole being adapted to slidably receive the rope intermediate the elastic sleeve and the second rope end, so that a loop is formed in the rope portion extending between the first and second clip holes.
Claim 6
Dependent Claim
74 words
The tie-down of claim 4 wherein: a. the first and second clip holes in the substantially flat surface are laterally and longitudinally offset; and b. the clip is fabricated with a tab bent laterally over the flat intermediate surface to loosely guide the rope intermediate the sleeve and the second rope end for permitting longitudinal sliding of the clip along the rope and for generally preventing rope lateral movement with respect to the clip.
Claim 7
Dependent Claim
14 words
The tie-down of claim 1 wherein the elastic sleeve is made of surgical tubing.
Claim 8
Dependent Claim
33 words
The tie-down of claim 6 wherein the surgical tubing has a length of approximately 3 to 4 inches, an outer diameter of approximately 0.68 inches and a wall thickness of approximately 0.09 inches.
Claim 9
Dependent Claim
12 words
The tie-down of claim 1 wherein said rope is a wire rope.
Claim 10
Dependent Claim
184 words
The tie-down of claim 1 further comprising: a. a first hook attached to the rope first end; b. a clip having first and second holes with substantially parallel axes through the flat surface, the rope second end being fastened to the clip at the second clip hole, the first clip hole being adapted to slidably receive the rope intermediate the elastic sleeve and the second rope end to thereby form a loop in the rope portion extending between the first and second clip holes; and c. a second hook slidably received over the loop in the rope portion extending between the first and second clip holes, the distance between the first and second hooks being adjustable by means of the clip independently of the tension in each sleeve to enable engaging the hooks with a load with the elastic sleeve in a relaxed condition and to enable stretching the sleeve and removing the rope slack therein to create a working length between the hooks equal to the length of the rope between the hooks, so that the load is retained only by the rope.
Claim 11
Dependent Claim
70 words
A rope adjustment device comprising a clip having a longitudinally extending flat plate portion with two longitudinally and laterally spaced holes through the plate portion and having parallel axes, the device having an upturned longitudinal flange and a spring finger joined to the longitudinal flange and projecting transversely over said plate portion to capture a rope therein and cooperating with said flange to confine said rope longitudinally on said plate.
Claim 12
Dependent Claim
