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 and a pressure sensor and pressure indicator to indicate the internal pressure of the ball. The inflation 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 pressure indicator provides a numerical indication of the internal pressure of the ball as measured or determined by the pressure sensor.

Claims

1. A sport ball having an integral inflation mechanism assembly with an integral pressure sensor and indicator, the ball comprising:

a flexible ball body adapted to retain pressurized air, the body defining an aperture;

an inflation mechanism assembly disposed in the aperture, the inflation mechanism assembly adapted to admit air into the ball body upon actuation thereby increasing the internal pressure of the ball; and

a pressure sensor and pressure indicator incorporated in the inflation mechanism assembly and adapted to indicate the internal pressure of the ball.

2. The sport ball of claim 1, wherein the pressure indicator provides a numerical indication of the internal pressure of the ball.

3. The sport ball of claim 1, wherein the inflation mechanism includes a cylinder defining a hollow interior and a piston disposed in the hollow interior, the piston movable between an extended position and an inserted position, the indicator being disposed on the piston and movable therewith.

4. The sport ball of claim 3, wherein the indicator is only visible when the piston is in the extended position or a position between the extended position and the inserted position.

5. The sport ball of claim 1, wherein said sport ball is a basketball.

6. The sport ball of claim 1, wherein said sport ball is a football.

7. The ball of claim 1, wherein said ball further comprises a counterweight positioned on said ball and of a suitable mass such that the center of mass of said ball coincides with the geometric center of said ball.

8. 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;

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; and

a pressure sensor and pressure indicator assembly incorporated within the pump assembly, the pressure sensor adapted to sense and measure the pressure of the interior region, and provide a signal to the indicator assembly representative of such measured pressure, the pressure indicator adapted to indicate the measured pressure of the pressure of the internal region of the ball.

9. The ball of claim 8, wherein the indicator is secured to the plunger and movable therewith.

10. The ball of claim 8, wherein the indicator provides a numerical indicator of the internal pressure of the rubber bladder.

11. The ball of claim 8, wherein said ball is selected from the group consisting of a basketball, a football, a soccer ball, and a volleyball.

12. The ball of claim 8, wherein said ball is a basketball.

13. The ball of claim 8, wherein said ball is a football.

14. The ball of claim 8, wherein said ball further comprises a counterweight positioned on said ball and of a suitable mass such that the center of mass of said ball coincides with the geometric center of said ball.

15. The ball of claim 8, further comprising:

a secondary inflation valve.

16. The ball of claim 8, said ball further comprising a second integral pump.

17. An inflatable ball having an integral inflation assembly, pressure sensor, and pressure indicator, the ball comprising:

a flexible ball body adapted to retain pressurized air;

an inflation mechanism integrally disposed in the ball body, the inflation mechanism having an actuator serving to admit air to the ball body;

a pressure sensor integral with the inflation mechanism and adapted to measure air pressure within the ball body; and

a pressure indicator integral with the inflation mechanism and in communication with the pressure sensor, the indicator adapted to provide an indication of the pressure measured by the pressure sensor.

18. The inflatable ball of claim 17, wherein the pressure indicator provides a numerical indication of the air pressure within the ball body.

19. The inflatable ball of claim 17, wherein the ball is a basketball.

20. The inflatable ball of claim 17, wherein the ball is a football.

21. The inflatable ball of claim 17, further comprising:

at least one counterweight secured to the ball body adapted to offset the weight of the inflation mechanism, pressure sensor, and pressure indicator.

22. The inflatable ball of claim 17 wherein the pressure indicator provides an alpha-character indication of the air pressure within the ball body.

23. The inflatable ball of claim 17 wherein the pressure indicator provides a graphical indication of the air pressure within the ball body.
