Abstract
A slip resistant shoe lace and a method to make same. A slip resistant shoe lace is provided by weaving strands having a conventional frictional coefficient with at least one strand having a higher frictional coefficiency, where the high-friction strands do not extend beyond the outer perimeter of the lace. The high-friction strands can be made by impregnating conventional strands with friction-enhancing substances such as resin or rubber, by using a unitary strand made of material such as rubber or soft plastic, or by using strands with grooves or serrations formed on its outside surface.
Claims17
A slip resistant shoe lace having a plurality interwoven strands of material and characterized by:
- a plurality of untreated strands of material;
- and
- at least one strand treated to have a coefficient of friction higher than that of said untreated strands, said untreated strands and said at least one high-friction treated strand being interwoven resulting in a single ply slip resistant lace.
A method of manufacturing a slip resistant shoe lace comprising the steps of:
- preparing an plurality of untreated strands;
- preparing at least one strand having a higher frictional coefficient than said untreated strands;
- and
- interweaving said untreated strands and said at least one high-friction strand together in such a manner that said at least one high-friction strand does not extend beyond an outer perimeter of the slip resistant shoe lace.
