Slip resistant shoelace and cord
The present invention is for a slip resistant shoelace comprising a shoelace tube and one or more friction inducing features such as a plurality of bumps made of rubber or silicone disposed over at least a portion of the length of the shoelace tube. The bumps can also be disposed over a rope in any desired manner to make it a slippage resistant rope. The plurality of bumps, when come in contact with each other or with any other surfaces in a tied knot, offer higher co-efficient of friction and thus resist slipping of the knot. A knot tied with the slip-resistant shoelace or the slip-resistant rope prevents slipping and prevents from getting loosened and untied inadvertently.
1. A slip resistant shoelace, comprising:
a shoelace tube; and
a plurality of bumps integrated with said shoelace tube, said plurality of bumps having a coefficient of friction greater than said shoelace tube without bumps;
wherein said plurality of bumps are integrated with said shoelace tube by one of: (i) being woven through a surface of said shoelace tube; and (ii) being adhered to the surface of said shoelace tube;
wherein said plurality of bumps increase frictional resistance and resist loosening of a knot tied with said shoelace when said plurality of bumps interact with each other in said knot, or with any other surface;
wherein said shoelace tube has a flat cross section with two sides; and
wherein said plurality of bumps are disposed on at least one side of said shoelace tube.
2. The slip resistant shoelace as in claim 1 , wherein said plurality of bumps are disposed over said shoelace tube in a helical manner.
3. The slip resistant shoelace as in claim 1 , wherein said plurality of bumps are disposed transversely over said shoelace tube.
4. The slip resistant shoelace as in claim 1 , wherein said plurality of bumps are disposed in a non-contiguous manner.
5. The slip resistant shoelace as in claim 1 , wherein said plurality of bumps are disposed in a contiguous manner over said shoelace tube.
6. The slip resistant shoelace as in claim 1 , wherein said plurality of bumps are disposed on two sides of said shoelace tube.
7. The slip resistant shoelace as in claim 1 , wherein said plurality of bumps are formed by the shoelace tube being woven to have the plurality of bumps.
8. A slip resistant cord, comprising:
an outer surface of said cord; and
a plurality of bumps integrated with said cord, said plurality of bumps having coefficient of friction greater than said outer surface without bumps;
wherein said plurality of bumps are integrated with the outer surface of said cord by one of: (i) being woven through the outer surface of said cord; and (ii) being adhered to the outer surface of said cord;
wherein said plurality of bumps increase frictional resistance when said plurality of bumps come in contact or interact or interfere with each other or with any other surface;
wherein said cord has a flat cross section with two sides; and
wherein said plurality of bumps are disposed on at least one side of said cord.
9. The slip resistant cord as in claim 8 , wherein said plurality of bumps are disposed over at least a portion of said cord.
10. The slip resistant cord as in claim 8 , wherein said plurality of bumps are disposed transversely over said outer surface.
11. The slip resistant cord as in claim 8 , wherein said plurality of bumps are disposed in a non-contiguous manner.
12. The slip resistant cord as in claim 8 , wherein said plurality of bumps are disposed in a contiguous manner over said outer surface.
13. The slip resistant cord as in claim 8 , wherein said plurality of bumps are disposed on two sides of said cord.
14. The slip resistant cord as in claim 8 , wherein said plurality of bumps are formed by the cord being woven to have the plurality of bumps.
