Abstract

A one-piece quick connector includes a tubular member and a collar. A pair of diametrically opposed actuating arms depend from the collar and lie in a first plane. A pair of diametrically opposed locking arms depend from the collar and lie in a second plane that is orthogonal to the first plane. The locking arms are disposed to engage a lip on the end of a conduit and are movable between a locking position and an unlocking position in response to movement of the actuating arms.

Claims

1. A quick connector comprising:

a tubular member; and

a collar coupled to the tubular member and disposed in spaced-apart relation therewith, wherein the tubular member engages a conduit as a male member and the collar engages the conduit as a female member;

a pair of locking arms depending from the collar and disposed in a first plane and configured to engage the conduit to retain the tubular member on the conduit; and

a pair of actuating arms depending from the collar and disposed in a second plane, the locking arms disengaging from the conduit in response to movement of the actuating arms.

2. The quick connector of claim 1 wherein the pair of locking arms are diametrically opposed and lie in the first plane and the pair of actuating arms are diametrically opposed and lie in the second plane, the first plane being orthogonal with the second plane.

3. The quick connector of claim 2 wherein the locking arms move in the first plane in response to movement of the actuating arms in the second plane.

4. The quick connector of claim 2 wherein the locking arms move in an unlocking direction in response to an actuating movement of the actuating arms.

5. The quick connector of claim 2 wherein the locking arms move between a locking position and an unlocking position in the first plane in response to movement of the actuating arms in the second plane.

6. The quick connector of claim 1 wherein the tubular member includes a flange extending radially outwardly therefrom and a pair of legs extending between the flange and the collar.

7. A quick connector comprising:

a tubular member; and

a collar coupled to the tubular member and disposed in spaced-apart relation therewith, wherein the tubular member engages a conduit as a male member and the collar engages the conduit as a female member and the collar includes an annular member having an outer surface and a bottom edge, a pair of actuating arms depending from the outer surface, and a pair of locking arms depending from the bottom edge, the actuating arms flaring outwardly away from the tubular member and the locking arms flaring inwardly towards the tubular member, the locking arms moving in a first direction in response to movement of the actuating arms in a second direction.

8. A quick connector comprising:

a tubular member; and

a collar coupled to the tubular member and disposed in spaced-apart relation therewith, wherein the tubular member engages a conduit as a male member and the collar engages the conduit as a female member and the collar includes an annular member having an outer surface and a bottom edge, a pair of actuating arms depending from the outer surface, and a pair of locking arms depending from the bottom edge, the actuating arms flaring outwardly away from the tubular member and the locking arms flaring inwardly towards the tubular member, wherein the actuating arms are diametrically opposed and lie in a first plane and the locking arms are diametrically opposed and lie in a second plane, the first plane being orthogonal with the second plane.

9. A quick connector comprising:

a tubular member including a flange and a conduit including a distal end having a lip, the locking arms cooperating with the tubular member and the flange to define an L-shaped channel for receiving the lip; and

a collar coupled to the tubular member and disposed in spaced-apart relation therewith, the collar including a pair of actuating arms depending therefrom and a pair of locking arms depending therefrom, the pair of locking arms moving in a first direction in response to movement of the actuating arms in a second direction.
