Abstract

A kick-strengthening practice soccer ball is given a little extra weight but preferably softened also for enhance shock absorption when kicked. The practice ball has an inflatable bladder, a carcass of tough durable material, and an intermediary sheath of substantially non-stretchable, flexible material for restraining expansion of the bladder when inflated to pressure. Thus the sheath thereby reduces the outward pressure on the carcass while also increasing the dimensional stability of the ball. A shock-absorbing weighting material interposed between either the bladder and sheath or sheath and carcass. The weighting material accounts for between about 4% and 40% of the total weight of the practice ball when inflated to pressure. If a nominal average weight for a standard matchball is taken to be between 14 to 16 ounces, the weighting material adds an additional increment from anywhere between about 1 and 10 ounces. Given the foregoing, the weighting material cooperatively weights the ball for kick-strengthening purposes as well as is shock-absorbing to soften the impact when kicked.

Claims

1. A progressive series of kick-strengthening practice soccer balls each of which at an intended inflation pressure of about one (1) atmosphere at sea level has a progressively different weight, wherein each practice soccer ball comprises:

an inflatable bladder; and

an outer casing, covering the bladder, formed of composite panels;

wherein all of the composite panels comprise an outer ply of tough durable carcass material and a subjacent ply of substantially non-stretchable, flexible sheath material for restraining expansion of the bladder when inflated to pressure and therefore reduce the outward pressure on the carcass material in combination with increasing the dimensional stability of each ball such that each ball of the series is approximately spherical and measures about the same in respect of outside diameter; and

,

wherein at least some panels furthermore include foam patches subjacent the sheath material, said foam patches being provided both to weight each ball for kick-strengthening purposes as well as to soften the impact when kicked, each ball of the series having a different number of patches such that ball weight increases in accordance with the increase in number of said patches.

2. The progressive series of kick-strengthening practice soccer balls of claim 1 wherein the weight of each inflated ball measures, excluding the foam, a baseline weight of about 14 to 16 ounces at sea level, plus an incremental amount more chosen from between about 1 and 10 ounces, the weight of the foam corresponding to the incremental amount.

3. The progressive series of kick-strengthening practice soccer balls of claim 1 wherein the weight of each inflated ball measures, excluding the foam, a baseline weight of about 14 to 16 ounces at sea level, plus an incremental amount more of about “

n”

ounce(s) such that “

n”

is an integer chosen from 1 to 10, the weight of the foam corresponding to the incremental amount.

4. The progressive series of kick-strengthening practice soccer balls of claim 1 wherein the panels are mated by sewn, seamed edges turned inward.

5. The progressive series of kick-strengthening practice soccer balls of claim 1 wherein:

each ball, excluding the foam, is substantially a FIFA International Matchball Standards ball that, when before use and inflated to between 0.6 and 1.1 atmospheres (600 and 1,100 millibar) at sea level;

is spherical,

has a circumference measuring not more than 28 inches (71 cm) and not less than 27 inches (68-½

cm), and

weighs not more than 16 ounces (396 grams) or less than 14 ounces (453 grams).

6. The progressive series of kick-strengthening practice soccer balls of claim 1 wherein:

for each ball the panels are provided in arrangements which utilize any of 32 in number, 18 in number, or 8 in number.

7. The progressive series of kick-strengthening practice soccer balls of claim 1 wherein:

for each ball the panels are provided in an arrangement of 32 in number, of which 12 are pentagonal and 20 are hexagonal, and, the foam is applied to one or the other of the pentagonal of hexagonal or panels only.

8. The progressive series of kick-strengthening practice soccer balls of claim 1 wherein:

the foam patches comprise one of synthetic, natural, or admixture of synthetic and natural foam or sponge rubber.

9. A progressive series of kick-strengthening practice soccer balls each of which at an intended inflation pressure of about one (1) atmosphere at sea level has a progressively different weight, wherein each practice soccer ball comprises:

an inflatable bladder;

a carcass of tough durable material;

an intermediary sheath of substantially non-stretchable, flexible material for restraining expansion of the bladder when inflated to pressure and therefore reduce the outward pressure on the carcass material in combination with increasing the dimensional stability of each ball such that each ball of the series is approximately spherical and measures about the same in respect of outside diameter; and

,

a shock-absorbing weighting material interposed between either the bladder and sheath or sheath and carcass, said weighting material being provided both to weight each ball for kick-strengthening purposes as well as is shock-absorbing to soften the impact when kicked, each ball of the series having a different amount of weighting material included such that ball weight increases in accordance with the increase in amount of weighting material.

10. The progressive series of kick-strengthening practice soccer balls of claim 9, wherein the weighting material comprises one of synthetic, natural, or admixture of synthetic and natural foam or sponge rubber.

11. The progressive series of kick-strengthening practice soccer balls of claim 9, wherein the weighting material comprises substantially a continuous layer.

12. The progressive series of kick-strengthening practice soccer balls of claim 9, wherein the weighting material is distributed in patches, substantially in a symmetric distribution in a spherical geometry, for lessening imbalance.

13. The progressive series of kick-strengthening practice soccer balls of claim 12, wherein the sheath is a woven material immediately subjacent and bonded directly to the carcass, the patches of weighting material being disposed between the sheath and bladder and being nominally fixed in place to the sheath during production by adhesive.

14. The progressive series of kick-strengthening practice soccer balls of claim 9 wherein the weight of the inflated ball, excluding the weighting material, measures a nominal baseline weight of about 15 ounces at sea level, plus an incremental amount more chosen from between about 1 and 10 ounces, the weight of the weighting material corresponding to the incremental amount.

15. The progressive series of kick-strengthening practice soccer balls of claim 9 wherein the weight of the inflated ball, excluding the weighting material, measures a nominal baseline weight of about 15 ounces at sea level, plus an incremental amount more of about “

n”

ounce(s) where “

16. The progressive series of kick-strengthening practice soccer balls of claim 9 wherein:

the ball, excluding the weighting material, is substantially a FIFA International Matchball Standards ball that, when before use and inflated to between 0.6 and 1.1 atmospheres (600 and 1,100 millibar) at sea level;

is spherical,

cm), and
