Abstract

A cord lock comprises a basic portion, and a first hook portion and a second hook portion integrated with the basic portion. The first hook portion and the second hook portion are formed at a first side of the basic portion. The first hook portion has a first concave portion for securing a cord. The second hook portion has a second concave portion for securing the cord. The opening direction of the first concave portion is different from that of the second concave portion. The first concave portion and the second concave portion bend the cord between the first hook portion and the second hook portion so as to secure the cord. The cord lock can be assembled on a cord at any time without having to be assembled on a product in advance and can be removed at any time, thereby making the production arrangement more flexible.

Claims

1. A cord lock comprising:

a foundation element;

two first cord hook elements integrally formed with the foundation element and each first cord hook element having a first concave element for securing a cord;

a second cord hook element integrally formed with the foundation element, the second cord hook element being disposed on a first side of said foundation element between the two first cord hook elements, the second cord hook element having a second concave element for securing the cord, wherein an opening direction of the first concave elements is different from an opening direction of the second concave element; and

a cord secured to the cord lock by pressing the cord into a gap between the first cord hook element and second cord hook element and stretching the cord, so that the cord enters the first and second concave elements, wherein releasing the cord after the cord enters the first and second concave elements causes the cord to rest in the first and second concave elements in a bent state to secure the cord to the cord lock,

wherein a gap between each of the first cord hook elements and the second cord hook element is smaller than a diameter of the cord, and a difference in height between a position of a trough of the first concave elements and a position of the trough of the second concave element is smaller than the diameter of the cord.

2. The cord lock according to claim 1, wherein the second cord hook element has an end segment in the shape of a triangle or semicircle.

3. The cord lock according to claim 1, wherein each of the first concave elements is in the shape of an inverted U.

4. The cord lock according to claim 1, wherein a second side of the foundation element has a hole for receiving a woven belt.

5. The cord lock according to claim 1, wherein a second side of the foundation element has a plate-shaped sewing tablet extending out of the foundation element.

6. The cord lock according to claim 1, wherein a second side of the foundation element has an additional pair of first cord hook elements and an additional second cord hook element for securing a second cord to the cord lock.

7. The cord lock according to claim 6, wherein the foundation element is equipped with holes for accommodating a woven belt.

8. The cord lock according to claim 1, wherein the cord lock is in the shape of a cylinder having rounded ends.
