摘要:
A method of making a game ball having a carcass comprising a foamed intermediate layer and a plurality of raised seams made from an outer layer is disclosed. The foamed intermediate layer may be formed from two sheets of foamed material. The sheets are shaped to have leaves that can be folded into the shape of a hemisphere with no gaps between adjacent leaves. The sheets are placed around a bladder, an outer layer is placed around the sheets, and the combination is heat molded. The seams are not made from strips of seam material placed on the outer layer of the carcass.
摘要:
Inflatable sportsballs such as volleyballs, soccer balls, basketballs, and footballs are disclosed having various volume/weight, surface area/weight, and or cover layer / carcass thickness ratios. Such sportsballs are particularly suitable for youth.

摘要:
An inflatable sport ball (10), such as a basketball, a football, a soccer ball, a volley ball or a playground ball, is provided with a self-contained inflation mechanism for inflating or more likely adding pressure to the ball. The mechanism is a self-contained, manually operable pumping chamber which is inside of the ball and which is operable from outside of the ball to compress the chamber and pump ambient air into the ball.
摘要:
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.
摘要:
Inflatable articles with self-contained mechanisms, such as sporting equipment, medical equipment, recreational devices and toys, preferably any inflatable article with at least one mechanism (30, 92, 124, 144, 172, 182, 200, 216, 224, 248, 272) for inflating or adding pressure to the article, or for deflating or removing pressure from the piece of equipment, such that the mechanism is located inside the article are disclosed.
摘要:
A method of manufacturing a sport ball (10) includes providing a fluid impervious bladder (12), providing apparatus for penetrating the bladder and including apparatus for receiving an object in sealing engagement, providing a plug (25) dimensioned and configured to engage in sealing relationship the apparatus for receiving in sealing engagement, inserting the plug into the apparatus for receiving, inflating the bladder, and forming additional layers (14, 16) of material on the bladder that is part of a complete sport ball. Thereafter, the method includes providing a self-contained inflation mechanism (82) dimensioned and configured to be disposed within the envelope of the sport ball and dimensioned and configured to engage the apparatus for receiving, removing the plug from the apparatus for receiving, and placing the inflation mechanism into the apparatus for receiving.
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 (5a, 5b, 5c) which is retained inside of the ball and which is operable from outside of the ball to pump ambient air into the ball. The pump additionally contains an integral pressure relief device to selectively relieve the pressure of the ball. Instead or in addition to the pressure relief device, the pump optionally contains a pressure-indicating device (72) to determine the relative pressure of the ball.

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.
