Abstract

Disclosed herewith is a ball bladder orifice formed by a ball bladder orifice saddle, an orifice set, an inset tube and a strength washer. Since the saddle is welded to the bladder on the inside of the bladder, it will much more firmly adhere to each other than the conventional ones, wherein the saddle is attached to the bladder from the outside of the bladder. There is a hook at the bottom end of the orifice set. The hook possesses two functions: one is to hold all of the pieces stably and firmly; and, the other is to give more strength to seal the tube fissure at the lower end of the inset tube to keep the air from leaking as more air is pumped into the ball.

Claims

1. A ball bladder orifice comprising:

an orifice saddle having a hollow body portion and a fringe portion extending radially from the top end of said body portion, the hollow body portion having two inside diameters, the larger diameter being closer to the fringe portion, the upper surface of said fringe portion being adapted for adhering to the inner surface of the ball bladder;

an orifice set adapted for insertion into said orifice saddle, said orifice set having a head portion, a neck portion, and a rounded hook portion, said head portion having a diameter and height substantially the same as the larger diameter portion in said orifice saddle, the upper surface of said head portion adapted for adhering to the inner surface of the ball bladder, said neck portion having a diameter and height substantially the same as the smaller diameter portion in said orifice saddle, said hook portion having a diameter greater than said neck portion so that said hook portion protrudes out of the lower end of the orifice saddle, a hollow shaft extending longitudinally through the entire length of said orifice set, said shaft having an enlarged diameter in the head portion of said orifice set;

an inset tube adapted for insertion into said orifice set, said tube having a radially extending flange on the outer periphery thereof, said inset tube being provided with a needle hole along the longitudinal axis thereof, the hole having two diameters, a larger diameter for the top portion of the tube and a fissure in the bottom portion of the tube, the diameter of the radially extending flange of the inset tube being substantially the same as the enlarged diameter of the head portion of said orifice set, the diameter of said inset tube being substantially the same as the diameter of the hollow shaft in said orifice set, the lower end of said tube extending out of the lower end of said orifice saddle;

and a strength washer having a centrally located aperture through which the top portion of the inset tube extends, the bottom surface of said washer adapted for adhering to the outside surface of the ball bladder.
