SPORT BALL WITH SELF-CONTAINED DUAL ACTION INFLATION MECHANISM

摘要

An inflatable sport ball (10), 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 (240) 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 (240) is a dual action pump allowing air to be added to the ball on both a forward stroke and reverse stroke.
