First Claim
Patent Images
1. An inflatable sport ball having an internal air pressure, said ball comprising:
- an internal pump attached to the ball, said pump including;
a cylinder having an air outlet into the ball,a valve attached to said air outlet regulating air flow from said cylinder into the ball,a hollow piston positioned in said cylinder, said piston operable to draw ambient air from outside the ball into said cylinder and to force the air within said cylinder through said valve into the ball;
an air pressure indicator positioned within said piston;
a needle extending from said piston toward said valve, said needle traversing said valve to connect said piston with the air pressure of the ball to position said air pressure indicator.

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 more likely adding pressure to the ball. The mechanism is a pump which is inside of the ball and which is operable from outside of the ball to pump ambient air into the ball. The pump contains an integral pressure-indicating device to readily determine the relative pressure of the ball.
