Abstract

A quick-connect system for a plumbing fixture includes an arm attachment, an intermediate fitting, and a collar. A first end of the arm attachment is mountable to a fluid conduit. At least a portion of the arm attachment at a second end of the arm attachment is sized to be received within the intermediate fitting and the collar. The collar is configured to slidably engage with the intermediate fitting and press against the intermediate fitting to deform the intermediate fitting over the second end of the arm attachment.

Claims (32)

1 . A quick-connect system for a plumbing fixture, comprising:

an arm attachment;

an intermediate fitting comprising a plurality of fingers, at least one finger of the plurality of fingers including a latch that extends radially outward from an outer surface of the at least one finger relative to a central axis of the intermediate fitting, at least one of the arm attachment and the intermediate fitting comprising a ball-joint configured to pivotably couple the plumbing fixture to a fluid conduit; and

a collar defining an inner protrusion that projects radially inwardly toward a central axis of the collar, the collar configured to press the intermediate fitting against an end portion of the arm attachment when engaging the inner protrusion with the latch.

2 . The quick-connect system of claim 1 , wherein engagement between the inner protrusion and the latch substantially prevents movement of the collar with respect to the intermediate fitting.

3 . The quick-connect system of claim 1 , wherein the inner protrusion defines a ledge disposed along an inner surface of the collar adjacent to a proximal end of the collar.

4 . The quick-connect system of claim 1 , wherein the intermediate fitting comprises a cylindrical protrusion that defines a central opening sized to at least partially receive the end portion of the arm attachment therein.

5 . The quick-connect system of claim 4 , wherein the cylindrical protrusion defines a step extending radially inwardly at a base of the plurality of fingers.

6 . The quick-connect system of claim 5 , wherein the end portion of the arm attachment is a ball-joint, and wherein the step is configured to slidably engage with the ball-joint to allow the intermediate fitting to pivot at the ball-joint.

7 . The quick-connect system of claim 5 , wherein an inner diameter of the intermediate fitting at the step is less than an inner diameter of the intermediate fitting at the base of the fingers above the step.

8 . The quick-connect system of claim 1 , wherein the arm attachment comprises a quick-connect subassembly, comprising:

a first portion;

a second portion; and

a retaining clip, the retaining clip engaged with the first portion and the second portion to detachably couple the first portion to the second portion.

9 . The quick-connect system of claim 8 , wherein the second portion includes an aperture extending radially therethrough, and wherein the retaining clip includes a locking tab extending through at least a portion of the aperture.

10 . The quick-connect system of claim 1 , wherein the arm attachment defines a fluid passage extending therethrough.

11 . A quick-connect system for a plumbing fixture, comprising:

an arm attachment;

an intermediate fitting comprising a plurality of fingers, at least one finger of the plurality of fingers including a latch that extends radially outward from an outer surface of the at least one finger relative to a central axis of the intermediate fitting;

a collar defining an inner protrusion that projects radially inwardly toward a central axis of the collar, the collar configured to press the intermediate fitting against an end portion of the arm attachment when engaging the inner protrusion with the latch; and

a T-junction fitting coupled to the intermediate fitting downstream of the arm attachment and the intermediate fitting, the T-junction fitting including a first passage and a second passage spaced apart from the first passage and oriented parallel to the first passage, the intermediate fitting extending radially away from the first passage and the second passage.

12 . The quick-connect system of claim 11 , further comprising a diverter insert disposed at least partially within the T-junction fitting, the diverter insert configured to direct fluid from the intermediate fitting in two opposing directions.

13 . A quick-connect system, comprising:

an arm attachment;

an intermediate fitting comprising:

a plurality of fingers, at least one finger of the plurality of fingers including a latch that extends radially outward from an outer surface of the at least one finger relative to a central axis of the intermediate fitting; and

a cylindrical protrusion defining a central opening sized to at least partially receive an end portion of the arm attachment therein, the cylindrical protrusion defining a step extending radially inwardly at a base of the plurality of fingers; and

a collar defining an inner protrusion that projects radially inwardly toward a central axis of the collar, the collar configured to press the intermediate fitting against the end portion of the arm attachment when engaging the inner protrusion with the latch, wherein each one of the plurality of fingers is curved so that an inner diameter of the plurality of fingers at an outer end of the fingers is less than an inner diameter of the plurality of fingers at the step.

14 . A quick-connect system for a plumbing fixture, comprising:

an arm attachment;

an intermediate fitting comprising a plurality of fingers, at least one finger of the plurality of fingers including a latch that extends radially outward from an outer surface of the at least one finger relative to a central axis of the intermediate fitting; and

a collar defining an inner protrusion that projects radially inwardly toward a central axis of the collar, the collar configured to press the intermediate fitting against an end portion of the arm attachment when engaging the inner protrusion with the latch, the arm attachment comprising a quick-connect subassembly configured to detachably couple a first portion of the arm attachment to a second portion of the arm attachment.
