Abstract

A squeeze-to-release quick connector for engaging a flanged male member includes a cylindrical body portion which is open at one end for receiving the male member and forms a conduit receiving adapter at its opposite end. An annular retainer ring is axially spaced from the open end and is attached to the body portion by two circumferentially opposed, generally parallel axially elongated beam members. Each beam member is affixed at one end to the retaining ring and at an opposed end to a mount located on the body portion axially spaced from the open end. Two circumferentially spaced detents extend inwardly from a retaining ring to capture the male abutment surface to effect positive engagement therebetween.

Claims

1. A squeeze-to-release quick connector adapted for selective locking engagement with a male member defining an outwardly extending abutment surface, said quick connector comprising:

a generally cylindrical, elongated body portion open at one end for receiving said male member and forming a conduit receiving adapter at an opposite end;

an annular retaining ring disposed concentrically with said body portion axially spaced from said open end;

two circumferentially opposed, generally parallel, axially elongated beam members interconnecting said retaining ring and body portion, each said beam member affixed at one end thereof to said retaining ring and at an opposed end thereof to a mount located on said body portion axially spaced from said open end such that said beam members are radially spaced from said body portion; and

at least two circumferentially spaced detents extending inwardly from said retaining ring to capture said abutment surface to effect positive engagement of said quick connector and male member, said retaining ring being adapted to be squeezed at angularly offset locations from said beam members to release said abutment surface from said detents for removal of said male member.

2. The quick connector of claim 1, wherein said mounts extend radially outwardly from the outside surface of said body portion.

3. The quick connector of claim 1, wherein said mounts are disposed approximately axially midway between the ends said body portion.

4. The quick connector of claim 1, wherein said mounts are axially disposed from said open end by a dimension that is approximately equal to one half the inner diameter of said body portion.

5. The quick connector of claim 1, wherein said beam members extend axially a distance approximately equal to the inner diameter of said body portion.

6. The quick connector of claim 1, wherein body portion, conduit receiving adapter, retaining ring and beam members are integrally formed.

7. The quick connector of claim 6, wherein said female part is formed of injection molded plastic.

8. The quick connector of claim 1, wherein said retaining ring defines two circumferentially opposed gripping surfaces adapted to be squeezed to effect said release on an outer surface thereof angularly offset from said beam members by approximately 90 degrees.

9. The quick connector of claim 1, wherein said retaining ring and beam members are constructed of resilient material.

10. The quick connector of claim 1, wherein said detents are substantially angularly aligned with said beam members.

11. The quick connector of claim 1, wherein each said detent comprises a radially tapered ramp surface facing away from said body portion and an abutment surface facing toward said body portion.

12. The quick connector of claim 11, wherein said retaining ring includes a skirt portion axially extending away from body portion.

13. The quick connector of claim 1, wherein said beam members extend generally parallel to the outside surface of said body portion.

14. The quick connector of claim 1, wherein said male member abutment surface comprises an annular upset flange formed near one end of said male member.

15. The quick connector of claim 1, wherein said retaining ring has a cross-sectional area which varies from a maximum positionally coinciding with said beam members to a minimum offset approximately 90 degrees therefrom.

16. The quick connector of claim 1, wherein said retaining ring comprises two opposed crescent shaped sectors joined at areas of minimum cross-section.

17. A squeeze-to-release quick connector assembly comprising:

a generally tubular male part defining an outwardly extending abutment surface; and

a female part including a generally cylindrical elongated body portion open at one end for receiving said male part and forming a conduit receiving adapter at an opposite end, said female part further including an annular retaining ring disposed concentrically with said body portion axially spaced from said open end, said retaining ring joined to said body portion by two circumferentially opposed parallel, axially elongated beam members, each member affixed at one end thereof to said retaining ring and at an opposed end thereof to a mount located on said body portion axially spaced from said open end such that said beam members are radially spaced from said body portion, said ring defining two circumferentially spaced inwardly extending detents operative to engage said abutment surface to effect interlocking of said male and female parts, said retaining ring being adapted to be squeezed at angularly offset locations from said beam members to release said abutment surface from said detents for removal of said male part.

18. A squeeze-to-release quick connector comprising:

a generally cylindrical body portion open at one end for receiving a male member;

a substantially annular retaining ring disposed concentrically with said body portion axially spaced from said open end;

at least one beam member interconnecting said retaining ring and a mount carried by said body portion axially spaced from said open end such that said beam members are radially spaced from said body portion; and

detent means carried by said retaining ring operative to capture an engagement surface on said male member in a relaxed condition and displaceable upon elastic distention of said retaining ring to release said male member, said retaining ring being adapted to be squeezed at angularly offset locations from said beam members to release said abutment surface from said detents for removal of said male member.
