1. A sport ball having an integral pump, said ball comprising:
- a flexible ball body adapted to retain pressurized air, said body defining an aperture;
a pump disposed in said aperture and retained within said ball body, said pump including (i) a cylinder, (ii) a piston disposed in said cylinder, said piston movable between an extended position and an inserted position, and (iii) a valve assembly configured to introduce air into said ball body upon movement of said piston from said extended position to said inserted position, and to also introduce air into said ball body upon movement of said piston from said inserted position to said extended position.

Abstract
An inflatable sport ball, such as a basketball, a football, a soccer ball, a volleyball or a playground ball, is provided with a self-contained inflation mechanism, or multiple self-contained inflation mechanisms, for inflating or adding pressure to the ball. The mechanism is a pump which is positioned and retained inside of the ball and which is operable from outside of the ball to pump ambient air into the ball. The pump is a dual action pump allowing air to be added to the ball on both a forward stroke and a reverse stroke.

5. An inflatable ball having an integral dual action pump assembly for changing air pressure within said ball, said ball comprising:
-
a rubber bladder defining an interior region adapted for retaining pressurized air;
an outer layer disposed about said rubber bladder; and
a pump assembly disposed in said interior region of said rubber bladder, said pump assembly including a movable plunger sealingly disposed within a cylinder secured to said rubber bladder, said plunger movable in both a forward stroke and a reverse stroke, said pump assembly adapted to transfer air to said interior region of said rubber bladder by moving said plunger in either said forward stroke or said reverse stroke. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15)

16. An inflatable sport ball having an integral dual action pump assembly for changing air pressure within said ball, said ball comprising:
-
a ball carcass defining an interior region for retaining air at a pressure greater than atmospheric pressure, said carcass defining an aperture between said interior region and the exterior of said ball;
a pump assembly disposed within said aperture and extending into said interior region, said pump assembly comprising;
(i) a pump cylinder including an open end, a nozzle end, and a cylindrical sidewall extending between said open end and said nozzle end, said cylinder defining a generally hollow interior; and
(ii) a pump plunger having a cap end, a sealing end, and a tubular wall extending between said cap end and said sealing end, said plunger defining a generally hollow interior accessible from said sealing end, said plunger movably disposed within said hollow interior of said cylinder between a forward position at which said sealing end of said plunger is proximate said nozzle end of said cylinder and a reverse position at which said sealing end of said plunger is proximate said open end of said cylinder;
wherein air is transferred to said interior region of said ball carcass upon movement of said plunger (i) from said forward position to said reverse position, or (ii) from said reverse position to said forward position. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A dual action pump adapted for incorporation in an inflatable sport ball, said pump comprising:
-
a cylinder having a head end, a nozzle end, and a cylindrical sidewall extending therebetween, said sidewall having an exterior surface and an oppositely directed interior surface, said cylinder defining a generally hollow interior chamber accessible from said head end and said nozzle end;
a movable plunger disposed in said hollow interior chamber of said cylinder, said plunger having a cap end, a sealing end, and a tubular wall extending therebetween, said plunger defining a hollow interior region accessible from said sealing end;
an air transfer tube extending within both said hollow interior chamber of said cylinder and said hollow interior region of said plunger, said air transfer tube secured to said nozzle end of said cylinder;
wherein said sealing end of said plunger contacts and provides a seal with said air transfer tube and said interior surface of said sidewall of said cylinder. - View Dependent Claims (30)
