Abstract

The combination of an inflatable bladder and valve for inflating the bladder for use with a ball cover and selectively insertable through an opening therein wherein the dimensions of the valve are such as to substantially fill the opening in the ball cover and providing a continuous surface therefor and which valve is maintained in its position within the opening by an outwardly extending flange portion which is urged into contact with the inner surface of the cover by action of the bladder as the bladder is expanded.

Claims

1. In the combination of an inflatable bladder and valve for inflating the bladder for use with a ball cover in which the cover is of a predetermined thickness having inner and outer surfaces and an opening of a predetermined size through which the bladder and valve may be selectively inserted when said bladder is in a deflated condition, the improvement comprising said valve means including a valve body having an air passageway for communicating between a valve inlet at one end of the valve body and a valve outlet at the other innermost end of the valve body, said valve having a continuous single flange of flexible material surrounding and extending laterally of said body from a point spaced from the inlet end of said body by a distance substantially equal to the predetermined thickness of the ball cover, said flange being of a dimension to continuously contact the internal surface of the ball cover surrounding the opening therein, said inlet of said valve having lateral dimensions substantially equal to the dimension of the opening in the ball cover, elastic compression ring means surrounding said body of said valve in airtight relationship and extending along a portion of said body between said continuous flange and said outlet end of said valve, said bladder having an opening therein defined by an inverted neck portion, said inverted neck portion surrounding and being attached in airtight relationship along said compression ring means so as to extend between said flange and said outlet of said valve, whereby said continuous flange is urged against the inner surface of said ball cover when said bladder in inflated.
