Elastic shoelace
View Patent ↗An elastic shoelace includes a first end and a second end, an elongate elastic core, a sheath, and an elongate friction member. The elongate elastic core extends between the first and second ends of the elastic shoelace, and the sheath includes an outer surface and surrounds the elongate elastic core. The elongate friction member is disposed in the sheath, and at least a portion of the elongate friction member protrudes past the outer surface of the sheath.
1. An elastic shoelace for a shoe, comprising:
a first end and a second end;
an elongate elastic core extending between the first and second ends;
a sheath surrounding the elongate elastic core, the sheath having an outer surface; and
an elongate friction member disposed in the sheath, wherein at least a portion of the elongate friction member protrudes past the outer surface of the sheath, wherein the elongate friction member is fabricated from a material having a greater coefficient of friction than the material from which the sheath is fabricated, wherein the elongate friction member is disposed around the core in a helical manner, and wherein a helical groove is defined between adjacent segments of the elongate friction member such that when two portions of the shoelace are laced through the shoe and overlap, a segment of the groove of the first portion retains a segment of the elongate friction member of the second, overlapping portion of the friction member.
2. The elastic shoelace of claim 1 , wherein the sheath is constructed from a woven fabric.
3. The elastic shoelace of claim 1 , wherein the elongate friction member is woven into the sheath.
4. The elastic shoelace of claim 1 , further including a first aglet disposed at the first end of the shoelace and a second aglet disposed at a second end of the shoelace.
5. The elastic shoelace of claim 1 , wherein the core is constructed from at least one of a rubber, plastic, natural rubber, and silicone material.
6. The elastic shoelace of claim 1 , wherein the elongate friction member extends from the first to the second end of the shoelace.
7. The elastic shoelace of claim 4 , further including a third aglet disposed near a center of the shoelace.
8. The elastic shoelace of claim 7 , wherein the third aglet is adapted to receive a branding or a logo.
9. The elastic shoelace of claim 1 , wherein the elongate friction member is elastic.
10. A shoelace comprising:
a first end and a second end;
an elastic core extending between the first and second ends;
a sheath surrounding the core, the sheath having an outer surface;
a friction member, the friction member being disposed helically in the sheath, wherein at least a portion of the friction member protrudes past the outer surface of the sheath and wherein the friction member is fabricated from a material having a greater coefficient of friction than the material from which the sheath is fabricated; and
a groove defined between adjacent segments of the friction member, wherein the groove is adapted to receive and retain an overlapping portion of the shoelace.
11. The shoelace of claim 10 , further including a first aglet disposed at the first end of the shoelace and a second aglet disposed at the second end of the shoelace.
12. The elastic shoelace of claim 11 , further including a third aglet disposed near a center of the shoelace.
