Abstract
A quick connect/disconnect faucet water conduit assembly includes at least one valve body and a spout nipple. There is a water tube extending from the valve body and a water tube extending from the spout nipple. A conduit has first and second terminations and there is a quick connect adapter attached to each of the first and second terminations. There are cooperating elements on each of the tubes and the quick connect adapters for locking the tubes to the adapters to thereby attach the valve body to the spout nipple.
Description
THE FIELD OF THE INVENTION
The present invention relates to a quick connect/disconnect faucet water conduit assembly which facilitates the connection between a spout nipple and the valve bodies which control the flow of water to the spout nipple. Present practice in the installation of faucets, particularly kitchen faucets, which require a below deck water connection between the valve bodies and the spout nipple, necessitates a mechanical connection at each end of a water conduit. These may be soldered connections, or they may use a nut and a threaded end on the valve body. Either type of connection is time consuming and requires the installer to spend a considerable period beneath the sink deck.
The present invention provides a hose assembly which has a quick connect/disconnect adapter at each end thereof. The adapters are sealingly attached to the hose, which may be flexible, and cooperate and interlock with a tube which extends down from the valve body and the spout nipple. The installer need only snap the quick connect adapter onto the end of the water tube from the valve body and the water tube from spout nipple and the installation is complete. The hose may be disconnected by manipulating the clip on the adapter if there is a necessity to change out the valve body or the spout nipple.
SUMMARY OF THE INVENTION
The present invention relates to a faucet water conduit assembly which may be quickly connected and disconnected to a valve body and a spout nipple.
A primary purpose of the invention is to provide a water conduit assembly which utilizes quick connect adapters to form a watertight connection between one or more valve bodies and a spout nipple.
Another purpose of the invention is to provide a water conduit assembly for the use described utilizing quick connect adapters which cooperate and interlock with a tube which extends outwardly from a faucet spout nipple and a faucet valve body.
Other purposes will appear in the ensuing specification, drawings and claims.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention is illustrated diagrammatically in the following drawings wherein:
FIG. 1
is a diagrammatic illustration of a kitchen faucet assembly and the water conduit connections therebetween;
FIG. 2
is an exploded view of the hose connection between any one of the faucet fixtures shown in
FIG. 1
;
FIG. 3
is a top plan view of the quick connect adapter; and
FIG. 4
is an enlarged view illustrating the connection between the adapter and the water tube from a valve body or spout nipple.
DESCRIPTION OF THE PREFERRED EMBODIMENT
FIG. 1
illustrates a typical kitchen faucet installation. There are control handles
10
and
12
on each side of a faucet spout
14
. Each of the handles
10
and
12
has a valve body indicated at
16
and
18
, respectively, and the spout
14
has a spout nipple
20
. Suitable valve cartridges, such as the MOEN 1224, may be positioned within the valve bodies. As is well known in the art, the handles control the flow of water from hot and cold water supplies to the spout nipple from which the water is discharged through the spout. The present invention is specifically concerned with the water connections between the valve bodies and the spout nipple.
Each of the valve bodies
16
and
18
has an inlet water conduit
22
and
24
extending downwardly therefrom, with each terminating in a connector
26
and
28
, respectively. The valve bodies in turn each have a water outlet tube
30
and
32
at the end thereof. Similarly, the spout nipple body
20
has a tube
34
extending downwardly therefrom. The tubes
30
,
32
and
34
and their connection to the hose assembly is illustrated in more detail in
FIGS. 2-4
.
Also illustrated in
FIG. 1
are a pair of water conduits or hoses
36
and
38
. The hose
36
is connected between a pout nipple fitting
40
and a valve body fitting
42
and the hose
38
is connected between the spout nipple fitting
40
and the valve body fitting
44
.
FIGS. 2-4
represent and illustrate the connection between a water tube, whether it be any one of tubes
30
,
32
and
34
, and the valve body fittings
40
,
42
and
44
.
Focusing first on the connection between the hose and the valve body fitting, indicated at
42
in
FIG. 2
, the fitting may be made of a suitable plastic and has a cylindrical portion
46
having an outwardly extending barbed projection
48
. The barbed projection
48
extends within a flexible portion
50
of the hose
36
. There is a seal ring
52
on the barbed projection, and as shown, this will cause an expansion area
54
in the flexible hose portion
50
. This provides a seal between the fitting and the hose. The barbs
56
function to secure the fitting to the hose. The combination of the barbed projection and seal provides a sealed secured connection between the hose and the fitting.
The tube
30
carries a shoulder
58
which will interlock with the quick connector indicated generally at
60
. The fitting
42
has a chamber
62
which will receive the tube
30
, as indicated in FIG.
4
. The chamber has a recess
64
which receives the seal
66
which forms a seal between the tube and the fitting. The shoulder
58
will be received in a second recess
68
adjacent the upper end of the chamber
62
when the tube is fully inserted into the fitting.
The fitting
42
includes a second chamber
70
within which is positioned a clip
72
which locks the tube within the fitting. The spring clip is movable back and forth within the chamber
70
to effect an interlock with the tube
30
and the shoulder
58
. The spring clip
72
has a pair of arms
74
connected together by a body portion
76
, with the spring clip including a further portion
78
which bears directly against the tube
30
in the fully connected position of FIG.
4
.
The clip
72
is movable within the chamber
70
and to effect a connection between the tube and the fitting, the clip will be in the extended position of FIG.
2
. The tube
30
will be inserted until the shoulder
58
bottoms and is positioned within the recess
68
. The clip
72
is then moved inwardly from the
FIG. 2
position to the
FIG. 4
position, in which case the clip overlies the upper end of the shoulder
58
, as illustrated in the drawings, to firmly hold the tube
30
within the fitting. If it is desired to disconnect the hose from either the valve body or the spout nipple, the arms
74
will be squeezed together, allowing the clip to be moved from the
FIG. 4
position to the
FIG. 2
position, which permits removal of the tube
30
.
Of importance in the invention is the ability to quickly connect the water conduits between valve bodies and the spout nipple without the installer requiring an excessive amount of time beneath the sink deck. The valve bodies and the spout nipple may be installed from above the sink deck and easily fastened in such position. The only installation which then must be made from beneath the deck is to attach the hose assembly between the valve body tubes and the tube connecting to the spout nipple. Although the invention is shown herein as having a single water conduit assembly which affects all connections, in some applications it may be desirable to have separate hose connections between the hot water supply valve body and the spout nipple, and a second hose which extends between the spout nipple and the cold water valve body. What is important is the quick disconnect assembly which permits a rapid seal-tight and secure connection with an audible snap between the various fixtures of the plumbing installation.
Whereas the preferred form of the invention has been shown and described herein, it should be realized that there may be many modifications, substitutions and alterations thereto.
