ABSTRACT:
A manifold of the type used in connection with inflatable articles and an integral flange that holds the manifold against rotation and retraction in relation to an inflatable article. The flange extends radially from a first end of the manifold and completely circumscribes it. The first end of the manifold is embedded in a thickened part of the inflatable article. The embedding is accomplished by introducing flowable elastomeric material into a mold within which the first end of the manifold is pre-positioned. Plural apertures are formed about the circumferential extent of the flange, and the flowable elastomeric material flows into the apertures so that the flange is an integral part of the inflatable article when the elastomeric material solidifies. The manifold further includes a longitudinally extending groove, a transverse groove and a radial bore. Gas is channeled by the transverse groove to the longitudinal groove and by the latter groove to the radial bore, and the radial bore is confluent with a central passageway of the manifold that communicates with the interior of the inflatable article. The transverse groove compensates for rotational and axial misalignment between the radial bore and a bore formed in an inflator member that slidably receives the manifold.
