Abstract
Abstract An assembly of valve body and mounting flange connected and sealed together by a novel crimped joint which strongly resists turning of the valve body relative to the flange. The valve body, for example, may be adapted for mounting in an inflation manifold, and the flange may be adapted for being sealed to the wall of an inflatable article at an opening through such wall. The invention includes a novel method of and an apparatus for forming the crimped joint.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
116 words
An assembly comprising a sleeve-like outer valve body and a mounting flange connected and sealed to the valve body, an end portion of the valve body extending through and beyond an opening in the mounting flange, an abutment on the valve body extending thereabout axially inwardly of and in contact with the mounting flange, the portion of the valve body extending beyond the mounting flange being split into a plurality of prongs, said prongs being spread and bent to overlie an axially outer face of the mounting flange and to thrust the mounting flange into forcible sealing engagement with the abutment thereby providing a connection strongly resisting turning of the valve body relative to the flange.
Claim 2
Dependent Claim
116 words
An assembly comprising a sleeve-like outer valve body and a mounting flange connected and sealed to the valve body, an end portion of the valve body extending through and beyond an opening in the mounting flange, an abutment on the valve body extending thereabout axially inwardly of and in contact with the mounting flange, the portion of the valve body extending beyond the mounting flange being split into a plurality of prongs, said prongs being spread and bent to overlie an axially outer face of the mounting flange and to thrust the mounting flange into forcible sealing engagement with the abutment thereby providing a connection strongly resisting turning of the valve body relative to the flange.
Claim 3
Dependent Claim
50 words
An assembly according to claim 1, wherein the mounting flange has a recess in the axially outer face thereof, said recess surrounding the opening in the mounting flange, the crimped connection between the valve body and mounting flange lying wholly within and being shielded by the walls of said recess.
Claim 4
Dependent Claim
33 words
An assembly according to claim 1, wherein the mounting flange is made of resilient plastic material and is locally deformed by the prongs as they thrust the mounting flange against the annular abutment.
Claim 5
Dependent Claim
28 words
An assembly according to claim 3, wherein the valve body has an interference fit with the opening in the mounting flange when the latter is in relaxed condition.
Claim 6
Dependent Claim
35 words
An assembly according to claim 3, wherein the prongs have re-entrant hook-like ends, said ends of the prongs being embedded in depressions formed thereby in the end surface of the mounting flange which they overlie.
Claim 7
Dependent Claim
62 words
An assembly according to claim 5, wherein the axially outer surface of the mounting flange has an axially outwardly convex part-toroidal surface coaxial of and closely surrounding the opening in the mounting flange, the opening and the outer surface of the valve body being circular cylindrical, and the prongs being bent radially outwardly and over said part-toroidal surface on the mounting flange.
Claim 8
Dependent Claim
44 words
An assembly according to claim 5, wherein the ends of the prongs are disposed radially outwardly of the valve body in a circle coaxial of and of a diameter which is not greatly less than that of the annular abutment on the valve body.
Claim 9
Dependent Claim
43 words
An assembly according to claim 3, wherein the ends of the prongs are disposed radially outwardly of valve body in a circle coaxial of and of a diameter which is not greatly less than that of the annular abutment on the valve body.
Claim 10
Dependent Claim
21 words
An assembly according to claim 1, wherein said prongs decrease in wall thickness from an innermost portion to an outermost portion.
