Abstract

A method of fastening a line to an object to form a continually adjustable nonreturn knot to adjust the length and tension of the line. The line is passed from one side of an object to another through one or more holes in the object and one portion is tucked under another portion of itself, creating a nip, to pinch the one portion against a surface of the object. The friction added by the nip is sufficient to prevent the line from being pulled through the knot in one direction but is insufficient to prevent it from being pulled through in the opposite direction. In variations of the embodiments of the knot, a release line is also attached to the line proximate the nip to relieve the friction added by the nip sufficiently to allow the line to be pulled through the knot in either direction.

Dependent claims

A method of fastening at least one line to an object to form a continually adjustable nonreturn knot, the at least one line having a working end, a working part, a standing end and a standing part, the object having a front surface portion and a rear surface portion and having at least three separate passages extending therebetween, the method comprising the steps of:

(a) threading the working end of the at least one line through a first passage in the object, from the rear surface portion to the front surface portion of the object;
(b) passing the working end of the at least one line from the front surface portion of the object to the rear surface portion thereof along a second passage spaced apart from the first passage;
(c) passing the working end of the at least one line from the rear surface portion of the object to the front surface portion thereof along a third passage, the first passage, the second passage, and the third passage being spaced apart from each other;
(d) passing the working end of the at least one line along the front surface portion of the object and threading the working end between the working part of the at least one line along the second passage and the front surface portion of the object to create a nip where the at least one line is pinched therebetween, the nip adding a sufficient amount of friction to that produced at other areas of contact between the working part of the at least one line and the object to prevent the at least one line from being pulled through the knot from the direction of the standing end but adding an insufficient amount of friction to prevent the at least one line from being pulled through the knot from the direction of the working end, thereby allowing the length and tension of the standing part of the line at least one to be continually adjusted by pulling on the working end of the at least one line;
and
(e) attaching a release line, proximate the nip, to the working part of the at least one line along the second passage, thereby providing a means for relieving the friction introduced at the nip sufficiently to allow the at least one line to be pulled through the knot from the direction of the standing end of the at least one line when the release line is pulled.

(a) threading the working end of the at least one line through a first passage in the object, from the rear surface portion to the front surface portion of the object;
(b) passing the working end of the at least one line from the front surface portion of the object to the rear surface portion thereof along a second passage spaced apart from the first passage, wherein passing the working end of the at least one line from the front surface portion of the object to the rear surface portion thereof along a second passage spaced apart from the first passage further includes threading the working end of the at least one line through the second passage in the object from the front surface portion to the rear surface portion of the object;
(c) passing the working end of the at least one line from the rear surface portion of the object to the front surface portion thereof along a third passage, the first passage, the second passage, and the third passage being spaced apart from each other;
and
(d) passing the working end of the at least one line along the front surface portion of the object and threading the working end between the working part of the at least one line along the second passage and the front surface portion of the object to create a nip where the at least one line is pinched therebetween, the nip adding a sufficient amount of friction to that produced at other areas of contact between the working part of the at least one line and the object to prevent the at least one line from being pulled through the knot from the direction of the standing end but adding an insufficient amount of friction to prevent the at least one line from being pulled through the knot from the direction of the working end, thereby allowing the length and tension of the standing part of the line at least one to be continually adjusted by pulling on the working end of the at least one line, the nip being disposed between the first passage and the second passage.

2 more elements

A method of fastening at least one line to an object to form a continually adjustable nonreturn knot, the at least one line having a working end, a working part a standing end and a standing part, the object having a front surface portion and a rear surface portion and having at least three separate passages extending therebetween, wherein the front surface portion and the rear surface portion of the object are convexly curved, the method comprising the steps of:

(a) threading the working end of the at least one line through a first passage in the object, from the rear surface portion to the front surface portion of the object;
(b) passing the working end of the at least one line from the front surface portion of the object to the rear surface portion thereof along a second passage spaced apart from the first passage;
(c) passing the working end of the at least one line from the rear surface portion of the object to the front surface portion thereof along a third passage, the first passage, the second passage, and the third passage being spaced apart from each other, wherein passing the working end of the at least one line from the rear surface portion of the object to the front surface portion thereof along a third passage spaced apart from the first passage further includes threading the working end of the at least one line through the third passage in the object from the rear surface portion to the front surface portion of the object;
(d) passing the working end of the at least one line along the front surface portion of the object and threading the working end between the working part of the at least one line along the second passage and the front surface portion of the object to create a nip where the at least one line is pinched therebetween, the nip adding a sufficient amount of friction to that produced at other areas of contact between the working part of the at least one line and the object to prevent the at least one line from being pulled through the knot from the direction of the standing end but adding an insufficient amount of friction to prevent the at least one line from being pulled through the knot from the direction of the working end, thereby allowing the length and tension of the standing part of the line at least one to be continually adjusted by pulling on the working end of the at least one line, the nip being disposed between the first passage and the second passage, the first passage, the second passage and the third passage being spaced apart from each other, whereby at least one of the curved surface portions increases the pinching force at the nip and controls the bend radius of the at least one line as it passes through the knot.
