Abstract

An improved cleat design is provided for article of footwear. At least one cleat is arranged on a bottom surface of the outsole, such that the cleat is disposed partially within the outsole and extends substantially perpendicular from the bottom surface of the outsole. The cleat includes an aperture such that a portion of the outsole extends through the aperture in a direction substantially parallel to the bottom surface of the outsole to retain the at least one cleat in a desired position relative to the outsole.

First claim

What is claimed is:

1. An article of footwear, comprising:
an outsole; and
at least one nodule integrally formed with and extending outwardly from a bottom surface of the outsole;
at least one cleat encapsulated partially within the at least one nodule and protruding therefrom in a direction substantially perpendicular to the bottom surface of the outsole, wherein the cleat is formed from metal and the at least one nodule having arcuate side surfaces extending from the bottom surface of the outsole to a distal end from which the cleat protrudes,
wherein the at least one cleat is in form of a plate defined by a top surface, a bottom surface that is ground engaging, and a first elongated planar surface substantially parallel with a second elongated planar surface, where a distance between the first and second elongated planar surfaces is less than a width of the first and second elongated planar surfaces, and a longitudinal axis of the first and second elongated planar surfaces is oriented substantially perpendicular to the bottom surface of the outsole; and
an aperture is formed in the plate proximate the top surface of the plate and extending between the first and second elongated planar surfaces, such that a portion of the at least one nodule extends through the aperture in a direction substantially parallel to the bottom surface of the outsole to retain the at least one cleat in a desired position relative to the outsole.

2. The article of footwear of claim 1 wherein the aperture is further defined as an oval with a longitudinal axis of the oval oriented substantially parallel to the bottom surface of the outsole.

3. The article of footwear of claim 1 wherein the at least one cleat includes a retention portion and the retention portion of the at least one cleat having a flange extending therefrom in a direction substantially parallel to the bottom surface of the outsole.

4. The article of footwear of claim 1 further comprises a midsole having a substantially planar bottom surface, wherein the at least one cleat is disposed entirely below the bottom surface of the midsole.

5. The article of footwear of claim 1 wherein cross-sectional area between the side surfaces of the at least one nodule increases continually from the distal end to the bottom surface of the outsole.

6. The article of footwear of claim 1 wherein the outsole is formed from thermoplastic polyurethane and the thermoplastic polyurethane having a hardness in the range of 60 D to 1174 D in accordance with the ASTM D2240 standard.

7. An article of footwear, comprising:
an outsole; and
at least one nodule coupled to a bottom surface of the outsole and extending outwardly therefrom;
at least one cleat encapsulated partially within the at least one nodule and protruding therefrom in a direction substantially perpendicular to the bottom surface of the outsole, wherein the cleat is formed from metal and the at least one nodule having arcuate side surfaces extending from the bottom surface of the outsole to a distal end from which the cleat protrudes,
wherein the at least one cleat is formed only by a plate defined by a top surface, a bottom surface, and a first elongated planar surface substantially parallel with a second elongated planar surface, where a distance between the first and second elongated planar surfaces is less than a width of the first and second elongated planar surfaces, and a longitudinal axis of the first and second elongated planar surfaces is oriented substantially perpendicular to the bottom surface of the outsole; and
an aperture formed in the plate proximate the top surface of the plate and extending between the first and second elongated planar surfaces, such that a portion of the at least one nodule extends through the aperture in a direction substantially parallel to the bottom surface of the outsole to retain the at least one cleat in a desired position relative to the outsole.

8. The article of footwear of claim 7 wherein the aperture is further defined as an oval with a longitudinal axis of the oval oriented substantially parallel to the bottom surface of the outsole.

9. The article of footwear of claim 7 wherein the at least one cleat includes a retention portion and the retention portion of the at least one cleat having a flange extending therefrom in a direction substantially parallel to the bottom surface of the outsole.

10. The article of footwear of claim 7 further comprises a midsole having a substantially planar bottom surface, wherein the at least one cleat is disposed entirely below the bottom surface of the midsole.

11. The article of footwear of claim 7 wherein cross-sectional area between the side surfaces of the at least one nodule increases continually from the distal end to the bottom surface of the outsole.

12. The article of footwear of claim 7 wherein the outsole is formed from thermoplastic polyurethane.

13. The article of footwear of claim 12 wherein the outsole formed from a thermoplastic polyurethane and the thermoplastic polyurethane having a hardness in the range of 60 D to 1174 D in accordance with the ASTM D2240 standard.

14. An article of footwear, comprising:
an outsole; and
at least one nodule integrally formed with and extending outwardly from a bottom surface of the outsole, wherein the at least one nodule having one or more arcuate side surfaces extending from the bottom surface of the outsole to a distal end from which the cleat protrudes, where cross-sectional area between the side surface increases continually from the distal end to the bottom surface of the outsole;
at least one cleat encapsulated partially within the at least one nodule and protruding therefrom in a direction substantially perpendicular to the bottom surface of the outsole, wherein the cleat is formed from metal and the at least one nodule having arcuate side surfaces extending from the bottom surface of the outsole to a distal end from which the cleat protrudes,
wherein the at least one cleat is formed only by a plate defined by a top surface, a bottom surface that is ground engaging and a first elongated planar surface substantially parallel with a second elongated planar surface, where a distance between the first and second elongated planar surfaces is less than a width of the first and second elongated planar surfaces, and a longitudinal axis of the first and second elongated planar surfaces is oriented substantially perpendicular to the bottom surface of the outsole;
an aperture formed in the plate proximate the top surface of the plate and extending between the first and second elongated planar surfaces, such that a portion of the at least one nodule extends through the aperture in a direction substantially parallel to the bottom surface of the outsole to retain the at least one cleat in a desired position relative to the outsole; and
a midsole having a substantially planar bottom surface, wherein the at least one cleat is disposed entirely below the bottom surface of the midsole and the at least one cleat includes an aperture such that a portion of the outsole extends through the aperture in a direction substantially parallel to the bottom surface of the outsole to retain the at least one cleat in a desired position relative to the outsole.
