Abstract

A child'"'"'s play ball constituted by an outer casing and an inner inflatable bladder. The outer casing is formed by contoured segments of high strength, non-stretchable fabric material stitched together to define, when the casing is fully expanded, a play ball of the desired shape and size, such as a football or soccer ball. The inner bladder is a conventional rubber balloon whose stem initially projects through an opening in the casing which is provided with a closure. The stem, after the balloon is inflated with air so that it conforms to the casing, is then tied to retain the air, the tied stem being concealed within the casing by the closure. The maximum safe diameter of the inflated balloon which is well below the diameter at which the balloon is close to its bursting point, is approximately equal to the maximum dimension of the expanded casing whereby the encased balloon has exceptional strength and the play ball may be subjected to rough handling.

Claims

1. A pneumatic play ball comprising:

(A) an outer case formed of non-stretchable, flexible fabric material which when the casing is fully expanded assumes a desired play ball configuration, said casing having a small opening therein to permit insertion into the casing of an inflatable bladder in its uninflated state, said casing opening being provided with a closure; and

(B) a mouth-inflatable bladder in the form of a balloon formed of a thin rubber skin having an air-passage stem which initially projects through said opening and is then outside the casing to permit mouth inflation of the balloon within the casing to an extent causing it to engage and conform to the inner surface of the casing and to provide internal air pressure imparting high bounce characteristics to the ball, after which the stem is tied and pushed within the casing and the opening is then sealed by the closure whereby the inflated balloon is fully encased by the outer casing and no portion thereof can be extruded therefrom when the ball bounces.

2. A play ball as set forth in claim 1, wherein said casing has the shape of a standard athletic play ball and is formed of contoured pieces of said fabric material which are joined together.

3. A play object as set forth in claim 2, wherein said ball is a football.

4. A play object as set forth in claim 2, wherein said ball is a soccer ball.

5. A play object as set forth in claim 2, wherein said closure is a zipper.

6. A play ball as set forth in claim 2, wherein said balloon has a maximum safe diameter that is well below the diameter at which the balloon is close to its bursting point and is approximately equal to the maximum dimension of the expanded casing, whereby the encased balloon has exceptional strength and the play ball may be subjected to rough handling.

7. A play ball as set forth in claim 1, wherein said fabric is closely-woven parachute cloth formed of synthetic plastic fibers.
