Abstract

Abstract A knot tying assistance contrivance that will aid in the knot tying of granny, reef, square, or similar knots, comprising parts that separate the loops of specified knots; that control the loop eye size between the inner and outer half knots; that release the loops; that attach loops to contrivance; and that position line with loop-separator structure, all parts assembled so that the outer ends of line such as string, cord, sash, ribbon or rope when tensioned in the knot tying process will not tangle, thereby the loops will be free running and not overcome by resisting forces, and when the contrivance is released, the granny, reef, square, or similar knot is secured holding a resultant tensioned inner half knot.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 197 words
A device that permits an inner half knot of a granny, reef, square or like knot to be brought to tension and secured with an outer half knot when the ends of the outer half knot are pulled, and is a knot tying assistance contrivance of original type consisting of curved and tapering surfaces comprising a loop-separator structure means keeping half knots of granny, square, reef or similar knots untied; with a means for transferring tension from the pulled line ends through an outer half knot, through the loop formed around the loop-separator, through the inner half knot to the line around the item, with said means being connected to the loop-separator structure; having a means for controlling the size of the loop eye between the outer and inner said half knots with said means connected to said loop-separator structure; and having a means for releasing the combination of the half knots and the loop-structure with said means connected to the loop-separator structure, thereby tying the line as tensioned with said knots; whereby the knot tying assistance contrivance functions as an assistant for tying of the specified knots leaving a secured knot and a tensioned tied line.
Claim 2
Independent Claim 197 words
A device that permits an inner half knot of a granny, reef, square or like knot to be brought to tension and secured with an outer half knot when the ends of the outer half knot are pulled, and is a knot tying assistance contrivance of original type consisting of curved and tapering surfaces comprising a loop-separator structure means keeping half knots of granny, square, reef or similar knots untied; with a means for transferring tension from the pulled line ends through an outer half knot, through the loop formed around the loop-separator, through the inner half knot to the line around the item, with said means being connected to the loop-separator structure; having a means for controlling the size of the loop eye between the outer and inner said half knots with said means connected to said loop-separator structure; and having a means for releasing the combination of the half knots and the loop-structure with said means connected to the loop-separator structure, thereby tying the line as tensioned with said knots; whereby the knot tying assistance contrivance functions as an assistant for tying of the specified knots leaving a secured knot and a tensioned tied line.
Claim 3
Dependent Claim 22 words
A device as defined in claim 1 having a means for holding the device to the line prior to tensioning the loops.
Claim 4
Dependent Claim 19 words
A device as defined in claim 1 having a means for retaining said knot tying contrivance to a fixture.
