Laces
A lace includes recesses, concave portions or cavities, effective for abutting against eyelets or hooks found in skates and effective to lock the laces at a given position when the lace is inserted into the eyelets or hooks.
1. A lace, comprising:
a structure of elastic material, the structure having at least two pairs of opposite sides;
a first pair of the opposite sides in which:
a first side of the first pair comprises alternating concave and convex portions;
a second side of the first pair comprises alternating concave and convex portions;
wherein the concave portions of the first side of the first pair match with the convex portions of the second side of the first pair along a longitudinal axis;
wherein the convex portions of the first side of the first pair match with the concave portions of the second side of the first pair along the longitudinal axis;
a second pair of the opposite sides in which:
a first side of the second pair comprises alternating concave and convex portions;
a second side of the second pair comprises alternating concave and convex portions;
wherein the concave portions of the first side of the second pair match with the concave portions of the second side of the second pair along the longitudinal axis; and
wherein the convex portions of the first side of the second pair match with the convex portions of the second side of the second pair along the longitudinal axis.
2. The lace of claim 1 , wherein each of the concave portions of each of the at least two pairs of opposite sides form cavities, the cavities being effective for abutting against eyelets or hooks found in skates and effective to lock the lace at a given position when the lace is inserted into the eyelets or hooks.
3. The lace of claim 1 , wherein the elastic material is braided.
4. The lace of claim 1 , wherein the at least two pairs of opposite sides are a single unitary continuous piece.
5. The lace of claim 1 , wherein the first pair of opposite sides is substantially orthogonal to the second pair of opposite sides.
6. The lace of claim 1 , wherein a distance between a peak of the convex portions and a trough of the concave portions of the first pair is greater than the distance between a peak point of the convex portions and a trough of the concave portions of the second pair.
7. The lace of claim 1 , wherein a distance between a peak of the convex portions and a trough of the concave portions of the first pair is at least two times greater than a distance between the peak of convex portions and a trough of the concave portions of the second pair.
8. The lace of claim 1 , wherein the lace has a thickness of about 3.5 mm to about 5 mm.
9. The lace of claim 8 , wherein a force in a range of about 5 to about 25 N is necessary to disengage the lace from an eyelet of a hockey skate and slide the lace therethrough.
10. The lace of claim 8 , wherein a force in a range of about 10 to about 25 N is necessary to disengage the lace from an eyelet of a hockey skate and slide the lace therethrough.
11. The lace of claim 8 , wherein a force in a range of about 200% to about 400% greater than a force to disengage a standard lace is necessary to disengage the lace from an eyelet of a hockey skate and slide the lace therethrough.
12. The lace of claim 1 , wherein the lace has a drape stiffness of about 5.8 cm to about 6.6 cm in accordance with FTMS 191A Method 5206.
13. The lace of claim 1 , wherein the lace has a tex yarn of about 7 000 tex to 14 000 tex in accordance with CAN/CGSB-4.2 No 5.2-M87 (2013) standard.
14. The lace of claim 1 , wherein the lace has a denier yarn of about 60 000 denier to about 130 000 denier in accordance with CAN/CGSB-4.2 No 5.2-M87 (2013) standard.
15. The lace of claim 1 , wherein a force of at least 5 N is necessary to disengage the lace from an eyelet of a hockey skate and slide the lace therethrough.
16. The lace of claim 1 , wherein a force in a range of about 2.5 to about 10 N is necessary to disengage the lace from an eyelet of an artistic skate and slide the lace therethrough.
17. The lace of claim 1 , wherein a force in a range of about 100% to about 300% greater than a force to disengage a standard lace is necessary to disengage the lace from an eyelet of an artistic skate and slide the lace therethrough.
18. The lace of claim 1 for use in combination with a skate having eyelets with a diameter of about 2.5 mm to about 3.5 mm.
19. The lace of claim 1 for use in combination with a skate having eyelets with a diameter of about 5.5 mm to about 6.5 mm.
20. The lace of claim 1 , wherein the lace width is measured between two most distant points on an axis that is orthogonal to an axis that is defined by the lace and extending along a length of the lace.
21. The lace of claim 1 , wherein the lace thickness is measured between two most distant points on an axis that is orthogonal to an axis that is defined by the lace and extending along a length of the lace.
