Claims
- 1. An all purpose nubbed cleat comprising:
- a cleat body having a top surface, a bottom surface and a periphery;
- a plurality of parallel first rib attached to the bottom surface each extending in both directions to the periphery of the body, a plurality of parallel, second ribs attached to the bottom surface at an angle differing from the angle of the first ribs and extending in both directions to the periphery of the body whereby the ribs intersect, said first and second ribs having an arcuate convex bottom surface, a plurality of polygonal nubs having a first end and a second traction end, the first end of the nubs being mounted on said bottom surface and over said ribs whereby the portion of said ribs uncovered by nubs being disposed between said nubs and between said nubs and said periphery of said cleat body.
- 2. A nubbed cleat according to claim 1 in which in the bottom surface of the ribs are in the same arcuate plane.
- 3. A nubbed cleat according of claim 2 wherein said nubs are a right circular cylinder having an upper end secured to the bottom surface of the cleat body.
- 4. A nubbed cleat according to claim 3 wherein said nubs have a lower end that is rounded.
- 5. A nubbed cleat according to claim 1 wherein said second reinforcing ribs are perpendicular to the first reinforcing ribs forming a rectangular grid within the periphery of said cleat body.
- 6. A nubbed cleat according to claim 5 in which the nubs are mounted at the intersections of the first and second ribs.
- 7. A nubbed cleat according to claim 5 wherein said reinforcing ribs have an essentially rectangular cross section.
- 8. A nubbed cleat according to claim 1 wherein said cleat body, said nubs and said reinforcing ribs are each formed from a low abrasion synthetic organic resin.
- 9. A nubbed cleat according to claim 8 wherein the resin is an elastomer.
- 10. A nubbed cleat according to claim 9 wherein said cleat body, said nubs and said reinforcing ribs are each formed from the same elastomer.
- 11. A nubbed cleat according to claim 8 wherein said cleat body, said nubs and said reinforcing ribs are separately formed elastomers having different strength properties.
- 12. A nubbed cleat according to claim 11 wherein said nubs are formed from a higher strength material as compared to said reinforcing ribs whereby traction with the ground surface in enhanced.
- 13. A nubbed cleat according to claim 1 wherein said cleat is mechanically attached to a shoe outsole.
- 14. A method of fabricating an all purpose nubbed cleat comprising the steps of:
- forming from a synthetic organic, elastomer resin a cleat body having a top surface, a bottom surface, a periphery, and a plurality of first parallel reinforcing ribs and a plurality of second, parallel reinforcing ribs both mounted on said bottom surface within said periphery the angle of the second ribs differing from the angle of the second ribs whereby the ribs intersect; and
- attaching a plurality of nubs to said ribs so as to downwardly depend from the bottom surface.
