Cord lock and adjustable securing device

A cord lock comprising

• a) an elongated member having a peripheral wall substantially surrounding a longitudinal axis, a first end portion with first opening means therein, a second end portion opposite said first end portion, second opening means in said second end portion, said second opening means including a non-cylindrical cross-section which includes a v-shaped portion;
• b) a first cord portion engaging said elongated member including an end of a cord extending through said first opening means;
• c) 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;
• d) locking means including serrated edges which simultaneously engaging both said first and said second cord portions securing each against significant axial movement;
• whereby the second cord portion will slide freely through said second opening means when the cord is drawn axially there through but will be drawn laterally into said v-shaped portion of said second opening means thereby locking said second cord portion against axial movement when the ends of said second cord portion are subjected to non-axial forces.

An adjustable securing cord comprising

• a) a length of cord having a first end, a second end, a first cord portion and a second cord portion;
• b) first securing means attached to said second end;
• c) a cord lock secured to said first end, said cord lock having means to define an adjustable-length loop of said length of securing cord said cord lock comprising
• i) an elongated member having a peripheral wall substantially surrounding a longitudinal axis, a first end portion with first opening means therein, a second end portion opposite said first end portion, second opening means in said second end portion said second opening means including a non-cylindrical cross-section which includes a v-shaped portion;
• ii) said elongated member engaging said first cord portion, said first end of said cord extending through said first opening means;
• iii) said elongated member engaging said second cord portion, said second end extending through said second opening means to adjustably define a size of a cord loop between the first and second cord portions;
• such that the second cord portion will slide freely through said second opening means when the cord is drawn axially there through but will be drawn laterally into said v-shaped portion of said second opening means thereby locking said second cord portion against axial movement when the ends of said second cord portion are subjected to non-axial forces;
• d) second securing means slidably attached to said adjustable-length loop;
• whereby said first and second securing means can be attached to first and second elements and said cord lock used to adjust said adjustable-length loop to a desired size.
