Abstract

A cleat provides traction in golf shoes (and shoes for other turf sports) without adversely affecting turf, while providing a desired level of traction under as many different conditions as possible, is resistant to being worn down on hard surfaces. The cleat has a hub with an attachment stud for attaching to a receptacle in a shoe sole, and at least one traction element extending substantially laterally from the flange to engage grass blades to provide traction without damaging turf. The traction element is deflectably attached to the hub, preferably by a resilient arm having a turf-engaging portion at the end thereof. The traction element is preferably cantilevered out of the plane of the hub, and in any event preferably deflects when a hard surface is encountered, to protect the turf-engaging portion from abrasion.

Claims

1. A removable cleat for use with an athletic shoe for providing to a user traction on a turf surface, said athletic shoe having a sole, said sole having a plurality of sole attachment means for attachment of removable cleats, said removable cleat having a relaxed configuration in absence of outside force on said cleat and being deflectable out of said relaxed configuration under action by outside force on said cleat, said cleat comprising:

a hub having a perimeter, a first side facing said sole and a second side facing away from said sole;

hub attachment means extending from said first side for attaching said hub to one of said sole attachment means;

an arm extending when in said relaxed configuration substantially laterally substantially from said perimeter of said hub; and

a turf-engaging portion attached to said arm and projecting when in said relaxed configuration away from, and substantially perpendicularly to, said second side of said hub for engagement with turf blades to provide traction without puncturing turf;

wherein;

said arm is deflectably attached substantially to said perimeter of said hub so that said arm deflects when said turf-engaging portion encounters a hard surface, to minimize wear of said turf-engaging portion by said hard surface.

2. The removable cleat of claim 1 wherein said at least one arm comprises a plurality of arms.

3. The removable cleat of claim 1 wherein said arm is resilient, said turf-engaging portion being deflectably attached substantially to said perimeter of said hub by virtue of said arm being resilient.

4. The removable cleat of claim 1 wherein said arm extends away from said second side of said hub, such that when said removable cleat is attached to a shoe sole, said arm is cantilevered away from said shoe sole.

5. The removable cleat of claim 4 wherein said arm is substantially resilient, whereby when said removable cleat is used on a hard surface, said arm deflects toward said shoe sole.

6. The removable cleat of claim 1 further comprising a gusset extending between said turf-engaging portion and said arm.

7. The removable cleat of claim 6 wherein said gusset extends between said turf-engaging portion and said arm in a direction toward said hub.

8. The removable cleat of claim 7 wherein said gusset is resilient.

9. The removable cleat of claim 1 wherein said hub, said arm and said turf-engaging portion are made from a single material.

10. The removable cleat of claim 9 wherein said single material is substantially resilient.

11. The removable cleat of claim 1 wherein said hub and said arm are made from a first material and at least a portion of said turf-engaging portion is made from a second material more resistant to abrasion than said first material.

12. The removable cleat of claim 11 wherein said turf-engaging portion has a tip for engaging said turf blades and said tip is made from said second material.

13. The removable cleat of claim 12 wherein said turf-engaging portion is made substantially entirely from said second material.

14. An athletic shoe comprising:

a sole;

a plurality of sole attachment means on said sole for attachment of removable cleats; and

a plurality of removable cleats for use with said athletic shoe for providing to a user traction on a turf surface, said removable cleat having a relaxed configuration in absence of outside force on said cleat and being deflectable out of said relaxed configuration under action by outside force on said cleat, said cleat comprising;

a hub having a perimeter, a first side facing said sole and a second side facing away from said sole;

hub attachment means extending from said first side for attaching said hub to one of said sole attachment means;

an arm extending when in said relaxed configuration substantially laterally substantially from said perimeter of said hub; and

a turf-engaging portion attached to said arm and projecting when in said relaxed configuration away from, and substantially perpendicularly to, said second side of said hub for engagement with turf blades to provide traction without puncturing turf;

wherein;

said arm is deflectably attached substantially to said perimeter of said hub so that said arm deflects when said turf-engaging portion encounters a hard surface, to minimize wear of said turf-engaging portion by said hard surface.

15. The athletic shoe of claim 14 wherein said at least one arm comprises a plurality of arms.

16. The athletic shoe of claim 14 wherein said arm is resilient, said turf-engaging portion being deflectably attached substantially to said perimeter of said hub by virtue of said arm being resilient.

17. The athletic shoe of claim 14 wherein said arm extends away from said second side of said hub, such that when said removable cleat is attached to said shoe sole, said arm is cantilevered away from said shoe sole.

18. The athletic shoe of claim 17 wherein said arm is substantially resilient, whereby when said removable cleat is used on a hard surface, said arm deflects toward said shoe sole.

19. The athletic shoe of claim 14 further comprising a gusset extending between said turf-engaging portion and said arm.

20. The athletic shoe of claim 19 wherein said gusset extends between said turf-engaging portion and said arm in a direction toward said hub.

21. The athletic shoe of claim 19 wherein said gusset is resilient.

22. The athletic shoe of claim 14 wherein said hub, said arm and said turf-engaging portion are made from a single material.

23. The athletic shoe of claim 22 wherein said single material is substantially resilient.

24. The athletic shoe of claim 14 wherein said hub and said arm are made from a first material and at least a portion of said turf-engaging portion is made from a second material more resistant to abrasion than said first material.

25. The athletic shoe of claim 24 wherein said turf-engaging portion has a tip for engaging said turf blades and said tip is made from said second material.

26. The athletic shoe of claim 25 wherein said turf-engaging portion is made substantially entirely from said second material.
