Abstract

Lace designs for footballs are provided. The laces have geometries that improve the aerodynamic characteristics of the football during flight. Additionally, the placement of the laces on the football is selected to maximize aerodynamic performance of the football during flight.

Claims

1. A football comprising:

a body; and

a molded lace element associated with the body, the molded lace element having a length associated with a longitudinal axis of the body and a width, the length being longer than the width,

wherein the molded lace element is substantially linear and the length of the molded lace element is positioned on the body at a first angle with respect to the longitudinal axis of the body, the first angle ranging from about 10 to about 25 degrees;

wherein the molded lace element has a center and two ends, and wherein the width of the molded lace element is wider in the center and tapered from the center to the two ends; and

wherein the molded lace element is configured to enhance an aerodynamic performance of the football.

2. The football according to claim 1, wherein the molded lace element protrudes from an exterior surface of the body.

3. The football according to claim 1, wherein the molded lace element is linear.

4. The football according to claim 2, wherein the molded lace element has a height that varies above a surface of the football along a length of the molded lace element.

5. The football according to claim 1, wherein the first angle ranges from about 12 degrees to about 17 degrees.

6. The football according to claim 1, wherein the first angle is about 12 degrees.

7. The football according to claim 4, wherein the molded lace element has a center and two ends, and wherein the element is higher above the surface of the football in the center of the element than on the two ends of the element.

8. The football according to claim 1, wherein the molded lace element is co-molded with the football.

9. The football according to claim 1, wherein the molded lace element is affixed to an interior surface of the football and configured to protrude through an exterior surface of the football.

10. A football comprising:

a body; and

a substantially linear molded lace element associated with the body, the molded lace element having a length associated with a longitudinal axis of the body and a width, the length being longer than the width;

wherein the length of the molded lace element is positioned on the body at a first angle with respect to the longitudinal axis of the body such that the length of the molded lace element crosses the longitudinal axis of the body;

wherein the molded lace element has a center and two ends, and wherein the width of the element tapers from the center to the two ends; and

wherein the molded lace element is configured to enhance an aerodynamic performance of the football.

11. The football according to claim 10, wherein the molded lace element is a projection that protrudes from an exterior surface of the body.

12. The football according to claim 10, wherein the first angle ranges from about 10 degrees to about 25 degrees.

13. The football according to claim 10, wherein the first angle ranges from about 12 degrees to about 17 degrees.

14. The football according to claim 10, wherein the first angle is about 12 degrees.

15. The football according to claim 11, wherein the substantially linear projection has a height that varies above a surface of the football along a length of the substantially linear projection.

16. The football according to claim 10, wherein the molded lace element is affixed to an interior surface of the football and configured to protrude through an exterior surface of the football.

17. A football comprising:

a body;

a molded lace element associated with the body the molded lace element having a length associated with a longitudinal axis of the body and a width, the length being longer than the width;

wherein the length of the molded lace element has a center and two ends, and wherein the width of the element varies along the length of the element, from a widest point proximate the center to a narrowest point proximate each of the two ends;

wherein the molded lace element is substantially linear and the length of the molded lace element is positioned on the body at an angle ranging from about 10 degrees to about 25 degrees with respect to a longitudinal axis of the body; and

wherein the molded lace element is configured to enhance an aerodynamic performance of the football.

18. The football according to claim 17, wherein the first angle ranges from about 12 degrees to about 17 degrees.

19. The football according to claim 17, wherein the first angle is about 17 degrees.

20. The football according to claim 17, wherein the first angle is about 12 degrees.
