Abstract

A yarn needle assembly may include a first needle member, a second needle member and a cable. The cable may have a first end coupled to an end of the first needle member and a second end coupled to an end of the second needle member. The cable may include a metal cable formed from a plurality of braided metal strands with a nylon coating surrounding the metal cable. The relationship between an overall diameter (D1) of the metal cable, a diameter (D2) of each of the individual metal strands and a total number (N) of braided metal strands may be defined by: (N)(D2)/D1<0.5.

Claims

1. A yarn needle assembly comprising:

a first needle member;

a second needle member; and

a cable having a first end coupled to an end of the first needle member and a second end coupled to an end of the second needle member, the cable including;

a metal cable formed from a plurality of braided metal strands with the relationship between an overall diameter (D1) of the metal cable, a diameter (D2) of each of the individual metal strands and a total number (N) of braided metal strands defined by;

(N)(D2)/D1<

0.5; and

a nylon coating surrounding the metal cable.

2. The yarn needle assembly of claim 1, wherein a needle size of the first and second needle members defined by a diameter of a main body of each of the first and second needle members is less than 4.0 millimeters.

3. The yarn needle assembly of claim 2, wherein the nylon coating defines a wall thickness of at least 0.2 millimeters and no greater than 0.3 millimeters.

4. The yarn needle assembly of claim 3, wherein the overall diameter (D1) of the metal cable is at least 1.3 millimeters and no more than 1.4 millimeters.

5. The yarn needle assembly of claim 4, wherein the total number (N) of braided metal strands is at least 40 and no greater than 60.

6. The yarn needle assembly of claim 5, wherein the diameter (D2) of each of the individual braided metal strands is at least 0.01 millimeters and no greater than 0.015 millimeters.

7. The yarn needle assembly of claim 1, wherein a needle size of the first and second needle members defined by a diameter of a main body of each of the first and second needle members is at least 4.0 millimeters.

8. The yarn needle assembly of claim 7, wherein the nylon coating defines a wall thickness of at least 0.2 millimeters and no greater than 0.4 millimeters.

9. The yarn needle assembly of claim 8, wherein the overall diameter (D1) of the metal cable is at least 1.3 millimeters and no more than 2.0 millimeters.

10. The yarn needle assembly of claim 9, wherein the total number (N) of braided metal strands is at least 40 and no greater than 80.

11. The yarn needle assembly of claim 10, wherein the diameter (D2) of each of the individual braided metal strands is at least 0.01 millimeters and no greater than 0.015 millimeters.

12. The yarn needle assembly of claim 1, wherein the end of the first needle member defines a first bore and the end of the second needle member defines a second bore with the first end of the cable being secured within the first bore and the second end of the cable being secured within the second bore.

13. The yarn needle assembly of claim 12, wherein a crimped engagement secures the first end of the cable within the first bore and the second end of the cable within the second bore.

14. The yarn needle assembly of claim 1, wherein the first needle member is a first knitting needle and the second needle member is a second knitting needle.

15. The yarn needle assembly of claim 1, wherein the first needle member is a first crochet hook and the second needle member is a second crochet hook.
