Cord lock and adjustable securing device
First Claim
1. A cord lock comprisinga) an elongated member having an outer peripheral wall substantially surrounding a longitudinal axis, a first end portion, a second end portion opposite said first end portion, first, second, and third openings in said elongated member, said second and third openings including a non-cylindrical cross-section which includes a v-shaped portion;
- b) said first opening comprising a slot extending laterally through said outer peripheral wall adjacent said first end portion;
c) an annular groove extending about said outer peripheral wall between said first end portion and said slot;
d) a first cord portion extending through said slot and being wrapped about said outer peripheral wall to lie in said annular groove such that a first pass of said first cord portion will impinge upon a second pass of said first cord portion lying in said annular groove to lock said first cord portion against movement;
e) a second cord portion engaging said elongated member, the second cord portion extending through said second and said third openings to adjustably define a size of a cord loop between the first and second cord portions;
whereby the second cord portion will slide freely through said second and third openings when the cord is drawn axially there through but will be drawn laterally into said v-shaped portion of said second and third openings thereby locking said second cord portion against axial movement when the ends of said second cord portion are subjected to non-axial forces.

Abstract
A frictional cord lock for use in locking one portion of a single length of cord relative to another. A first embodiment includes a cylindrical, barrel-shaped member having a cylindrical wall substantially surrounding a longitudinal axis, has a first cord end fixed in one opening in the cord lock. Second and third tear-drop shaped openings lie along a common axis that forms an angle with the longitudinal axis and receive a second portion of the cord, the first opening lying vertically between said the second and third openings. The cord slides freely in second and third openings when pulled along their common axis but locks when subjected to non-axial forces. The non-axial forces pull the cord into the v-shaped portion of the openings pinching the cord and securing them in place. A second embodiment employs a generally horizontal v-shaped channel to lock the cord in place. A third embodiment has an open side enabling the cord to be easily threaded into the lock and uses a serrated, slidable wedge lock to effect positive locking, while a fourth embodiment utilizes a rotational locking ring with serrated portions to engage the cord and provide non-slip adjusted locking.

7. A cord lock comprising
e) an elongated generally barrel shaped member having a peripheral wall substantially surrounding a longitudinal axis, a first end portion, a second end portion opposite said first end portion, first and second opening means in said elongated member, said first and second opening means each including a non-cylindrical cross-section which includes a v-shaped portion; -
f) a first cord portion engaging said elongated member and extending through said first opening means;
g) a second cord portion engaging said elongated member, the second cord portion extending through said second opening means to adjustably define a size of a cord loop between the first and second cord portions;
h) locking means including a first element with serrated edges for engaging said first cord portion and a second element with serrated edges for engaging said second cord portion, said first and second elements each comprising one of a pair of locking rings which each encircle said elongated member and are independently adjustable to secure each said first and second cord portion, respectively, against significant axial movement;
whereby said first and second cord portions will slide freely through said first and second opening means when the cord is drawn axially there through but will be drawn laterally into said v-shaped portion of said first and second opening means thereby locking said first and second cord portions, respectively, against axial movement when the ends of said first and second cord portions are subjected to non-axial forces. - View Dependent Claims (8, 9, 10, 11)
