  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • With reference now to the drawings, and particularly to FIG. 1, there is shown a perspective view of a football having tail fins with a [0030] straight length 1. With reference to FIGS. 2-4, the football having tail fins with a straight length 1 includes a football body 10 and at least two straight length tail fins 12 which extend outward from a rear of the football body 10. However, four straight length tail fins 12 are shown in the FIGS. 1-4. The straight length tail fins 12 are preferably spaced equidistance from each other around the outer diameter of the football body 10 at a rear thereof. A longitudinal axis 14 acts as the center of the football body 10. Each of the straight length tail fins 12 are located at an angle “A” relative to the longitudinal axis 14. A front of each straight length tail fins 12 are preferably disposed before the longitudinal axis 14 at a distance “B.”
  • A [0031] bevel 20 is preferably formed on a back edge of each straight length tail fin 12. A front perimeter 16 of each straight length tail fin 12 preferably has a convex curvature and a rear perimeter 18 preferably has a concave curvature to facilitate better air flow and less drag. The angled tail fins 12 cause the football having tail fins 1 to rotate when thrown with the unexpected result of loft. The following dimensions are given by way of example and not by way of limitation. Angle “A” is preferably between 0-14.9 degrees. Dimension “B” is preferably 0.06-0.25 inches for a football body 10 having a 3.5 inch outer diameter. Dimension B will increase or decrease depending upon the size of the football body 10.
  • The [0032] football body 10 and the straight length tail fins 12 may be molded as a single assembly or the straight length tail fins 12 may be separate pieces which are attached to the football body 10. If separate pieces, it is preferable that a slot 22 be formed in a rear of the football body 10 for each tail fin 12. Each slot 22 is sized to firmly receive a single tail fin 12. The tail fins 12 may also be additionally secured in the slots with some type of adhesive. Other methods of attaching the tail fins 12 to the football body 10 are also possible, such as gluing the tail fins 12 to the outer perimeter of the football body 10 (without the slots 22). With reference to FIG. 2a, the football having tail fins with a straight length 1 may be placed in a “standing” position by placing thereof on its tail fins 12. The “standing” position is convenient for kicking the football having tail fins 1.
  • FIGS. [0033] 5-8 show a football having tail fins with a curved length 2. The football having tail fins with a curved length 2 includes a football body 24 and at least two curved length tail fins 26 which extend outward from a rear of the football body 24. The curved length tail fin 26 is an improvement over the straight length tail fin 12. The curvature of the length decreases the amount of the fin's drag while traveling through the air. The rotation of the football having tail fins 2 is also improved compared with the straight length tail fins 12. Four curved length tail fins 26 are shown in the FIGS. 5-8. The curved length tail fins 26 are preferably spaced equidistance from each other around the outer diameter of the football body 10. A longitudinal axis 28 acts as the center of the football body 24. Each of the curved length tail fins 26 are located at an angle “C” relative to the longitudinal axis 28. A front of each curved length tail fin 26 is preferably disposed before the longitudinal axis 28 at a distance “D.”
  • A [0034] bevel 30 is preferably formed on a back edge of each curved length tail fin 26. A front perimeter 32 of each curved length tail fin 26 preferably has a convex curvature and a rear perimeter 18 thereof preferably has a concave curvature to facilitate better air flow and less drag. The curved length tail fins 26 cause the football having tail fins 2 to rotate when thrown with the unexpected result of loft. The following dimensions are given by way of example and not by way of limitation. Angle “C” is preferably between 0-14.9 degrees. Dimension D is preferably 0.50-1.00 inches for a football body having a 3.5 inch outer diameter.
  • The [0035] football body 24 and the curved length tail fins 26 may be molded as a single assembly or the curved length tail fins 26 may be separate pieces which are attached to the football body 24. If separate pieces, it is preferable that a curved slot 36 be formed in a rear of the football body 24 for each tail fin 26. Each slot 36 is sized to firmly receive a single tail fin 26. The tail fins 26 may also be additionally secured in the curved slots 36 with some type of adhesive. Other methods of attaching the tail fins 26 to the football body 24 are also possible, such as gluing the tail fins 26 to the outer perimeter surface of the football body 24 (without a slot 36). The football having tail fins with a curved length 2 may be placed in a “standing” position by placing thereof on its tail fins 26 similar to that shown in FIG. 2a for the football having tail fins 1.
  • FIGS. [0036] 9-12 show a second embodiment of a football having tail fins. A football having rear fins 3 includes a football body 38, a longitudinal pole member 40, and at least two rear fins 42. However, three straight length tail fins 12 are shown in the FIGS. 9-12. The longitudinal pole member 40 extends from a rear of the football body 38. The rear fins 42 are attached to the longitudinal pole member 40. The rear fins 12 are preferably spaced equidistance from each other around the outer diameter of the football body 38. A longitudinal axis 44 acts as the center of the football body 38 and the longitudinal pole member 40. Each of the rear fins 42 are not parallel relative to the longitudinal axis of the football body. Each of the rear fins 42 preferably spiral around the longitudinal pole member 40. Each of the rear fins 42 gradually increase in height from the football body 38 to an end of the longitudinal pole member 40.
  • The spiral orientation of the [0037] tail fins 12 cause the football having rear fins 3 to rotate when thrown. The longitudinal pole member 40 and the rear fins 42 may be molded as a single assembly or the straight length tail fins 42 may be separate pieces attached to the football body 38. If separate pieces, it is preferable that a spiral groove 46 be formed in the longitudinal pole member 40 for each rear fin 42. Each spiral groove 46 is sized to receive a single rear fin 42. The rear fins 42 may also be additionally secured in the spiral grooves 46 to the football body 10 with some type of adhesive. Other methods of attaching the rear fins 42 to the football body 38 are also possible, such as gluing the rear fins 42 to the an outer perimeter of the longitudinal pole member 40 (without a spiral groove 46).
  • FIG. 13 shows a football having tail fins with a [0038] straight length 4 and weighted rod with insertable weights 48. The football having tail fins 4 has an opening 56 formed in a rear thereof. The opening 56 continues through substantially the length of the football having tail fins with a straight length 4, but does not break through a front thereof. The weighted rod with insertable weights 48 includes a rod body 50 and a plurality of weights 52.
