Football lacing system
A football lacing system having a molded backbone with a series of spaced finger grooves separated by resilient ridges to insure proper hand placement for throwing a spiral pass. The backbone is preferably molded of thermal plastic rubber and is secured over the bladder seam of the exterior football covering by lacing that extends between paired lace holes along the length of the bladder seam.
1. A football lacing system for a football having a bladder, a cover with a bladder seam, and a plurality of paired lacing holes spaced along opposite sides of said seam, said lacing system comprising:
a backbone member to overlie said football bladder seam, said backbone member having finger grooves spaced along the length thereof in registry with said paired lacing holes and also having ridges spaced along the length thereof between said finger grooves and projecting in height above said finger grooves; and
closure laces extending between said paired lacing holes to overlie said finger grooves of said backbone member;
whereby said laces secure said backbone member to the football and close said bladder seam while said ridges provide finger separation along said backbone to improve gripping of the football.
2. The football lacing system as in claim 1 , said closure laces having a width less than the diameter of said lacing holes in order to pass therethrough and having a thickness T.
3. The football lacing system as in claim 2 , said finger grooves of said backbone member having a maximum height of at least the thickness T of said closure laces.
4. The football lacing system as in claim 3 , said ridges of said backbone member having a maximum height of at least six times the thickness T of said closure laces.
5. The football lacing system as in claim 3 , said finger grooves of said backbone member being uniformly arcuate along the longitudinal length thereof and being sized such that the side contours of said ridges provide contact with the user's fingers when gripping the football.
6. The football lacing system as in claim 1 , said finger grooves of said backbone member having a minimum lateral width less than the lateral distance between said paired lacing holes.
7. The football lacing system as in claim 6 , said ridges of said backbone member having a maximum lateral width greater than the lateral width of said finger grooves.
8. The football lacing system as in claim 7 , said ridges of said backbone member having a maximum lateral width equal to or greater than the lateral distance between said paired lacing holes.
9. The football lacing system as in claim 1 , said backbone member being molded of thermal plastic rubber to facilitate tactile contact with the user's fingers.
10. A football lacing system for a football having a bladder, a cover with a bladder seam, and a plurality of N pairs of lacing holes uniformly spaced apart and uniformly spaced along opposite sides of said seam, said lacing system comprising:
a backbone member to overlie said football bladder seam, said backbone member having N finger grooves spaced along the length thereof in registry with said N pairs of lacing holes and also having N−1 ridges spaced along the length thereof between said N finger grooves and projecting in height above said finger grooves; and
closure laces extending between said pairs of lacing holes to overlie said finger grooves of said backbone member;
whereby said laces secure said backbone member to the football and close said bladder seam while said ridges provide finger separation along said backbone to improve gripping of the football.
11. The football lacing system as in claim 10 , said closure laces having a width less than the diameter of said lacing holes in order to pass therethrough and having a thickness T.
12. The football lacing system as in claim 11 , said finger grooves of said backbone member having a maximum height of at least the thickness T of said closure laces.
13. The football lacing system as in claim 12 , said ridges of said backbone member having a maximum height of at least six times the thickness T of said closure laces.
14. The football lacing system as in claim 12 , said finger grooves of said backbone member being uniformly arcuate along the longitudinal length thereof and being sized such that the side contours of said ridges provide contact with the user's fingers when gripping the football.
15. The football lacing system as in claim 10 , said finger grooves of said backbone member having a minimum lateral width less than the uniform lateral distance between any said pair of lacing holes.
16. The football lacing system as in claim 15 , said ridges of said backbone member having a maximum lateral width greater than the lateral width of said finger grooves.
17. The football lacing system as in claim 16 , said ridges of said backbone member having a maximum lateral width equal to or greater than the uniform lateral distance between any said pair of lacing holes.
18. The football lacing system as in claim 10 , said backbone member being molded of thermal plastic rubber to facilitate tactile contact with the user's fingers.
