An elastic band includes an elongate elastic core, a sheath, and an elongate friction member. The elongate elastic core comprising a continuous loop and the sheath has an outer surface and surrounds the elongate elastic core. The elongate friction member is disposed in the sheath, such that at least a portion of the elongate friction member protrudes past the outer surface of the sheath.
1. An elastic band, comprising:
an elongate elastic core comprising a continuous loop;
a sheath wrapped around and enclosing the elongate elastic core, the sheath having an inner surface facing the elongate elastic core and an outer surface facing outwardly away from the elongate elastic core; and
an elongate friction member disposed in the sheath and fabricated from a material having a greater coefficient of friction than the material from which the sheath is fabricated, wherein at least a portion of the elongate friction member protrudes past the outer surface of the sheath.
2. The elastic band of claim 1 , wherein the sheath is constructed from a woven fabric.
3. The elastic band of claim 2 , wherein the woven fabric is constructed from at least one of cotton, silk, linen and metal material.
4. The elastic band of claim 1 , wherein the elongate friction member is woven into the sheath.
5. The elastic band of claim 1 , wherein the elongate friction is disposed around the core in a helical manner.
6. The elastic band of claim 1 , wherein the elastic core includes a first and a second end that are fixedly connected with at least one of an adhesive material and a metal connecting part.
7. The elastic band of claim 1 , wherein the core is constructed from at least one of a rubber, plastic, natural rubber, and silicone material.
8. The elastic band of claim 1 , wherein a majority of the elongate friction member protrudes past the outer surface of the sheath.
9. The elastic band of claim 1 , wherein a minority of the elongate friction member protrudes past the outer surface of the sheath.
10. The elastic band of claim 1 , wherein at least a portion of the elongate friction member is fixedly attached to the elongate elastic core.
11. An elastic band, comprising:
an inner elongate elastic member comprising a continuous loop;
an outer woven member wrapped around and enclosing the inner elongate elastic member, the outer woven member having an inner surface facing the elongate elastic member and an outer surface facing outwardly away from the elongate elastic member; and
an elongate protruding member attached to the outer woven member and fabricated from a material having a greater coefficient of friction than the material from which the outer woven member is fabricated, wherein at least a portion of the elongate protruding member protrudes past the outer surface of the outer woven member and wherein at least a portion of the outer woven member and at least a portion of the elongate protruding member are fixedly attached to the inner elongate elastic member.
12. The elastic band of claim 11 , wherein the outer woven member is constructed from at least one of cotton, silk, linen and metal material.
13. The elastic band of claim 11 , wherein the elongate protruding member is disposed around the inner elongate elastic member in a helical manner.
14. The elastic band of claim 11 , wherein the inner elongate elastic member includes a first and a second end that are fixedly connected with at least one of an adhesive material and a metal connecting part.
15. The elastic band of claim 11 , wherein a majority of the elongate friction member protrudes past the outer surface of the sheath.
16. The elastic band of claim 11 , wherein the inner elongate elastic member has a generally rectangular cross-sectional shape.
17. The elastic band of claim 11 , wherein at least a portion of the outer woven member is fixedly attached to the elongate protruding member.
18. The elastic band of claim 17 , wherein the outer woven member is fixedly attached to the elongate protruding member at a connection between a first and a second end of the inner elongate elastic member.
19. The elastic band of claim 11 , wherein the portion of the outer woven member and the portion of the elongate protruding member are fixedly attached to the inner elongate elastic member at a connection between a first and a second end of the inner elongate elastic member.
20. An elastic band, comprising:
an elongate elastic core having a first end fixedly connected to a second end, the core comprising a continuous loop;
a woven sheath wrapped around and enclosing the elongate elastic core, the sheath having an inner surface facing the elongate elastic core and an outer surface facing outwardly away from the elongate elastic core; and
an elongate friction member woven into the sheath and disposed around the core in a helical manner, wherein at least a portion of the elongate friction member protrudes past the outer surface of the sheath, and wherein the elongate friction member is fabricated from a material having a greater coefficient of friction than the material from which the woven sheath is fabricated.
