When the mixer cartridge is sealingly connected to the tail, it is preferred that the hot water coupler, the cold water coupler and the outlet coupler are received into the hot water channel, the cold water channel and the outlet channel, respectively, in a push fit.
The hot water and cold water passages of the tail are configured to deliver hot water and cold water received via the respective hot water and cold water inlets to the hot water coupler and cold water coupler, respectively, of the mixer cartridge for mixing. The mixed water is then conveyed via the outlet of the mixer drum to the outlet channel of the tail. The outlet channel of the tail then delivers the mixed water to an outlet, which is preferably fluidly coupled to the outlet of the mixer tap.
Each of the one or more sealing means is preferably an O-ring. Each channel preferably exhibits a circular cross-section and includes an inner circumferential recess sized to receive an O-ring. In a preferred embodiment, each channel includes two inner circumferential recesses configured to receive a respective O-ring. The two circumferential recesses are preferably spaced apart along the length of the channel. Each of the couplers also preferably presents a circular cross-section along at least a portion of its length that is complementary to the cross-section of the channel so that the coupler can be received into the channel in a push-fit manner with a tight fit. Advantageously, the O-ring is configured to sealingly connect the mixer barrel to the tail portion when the coupler is received into the channel in a push-fit manner. Furthermore, the O-ring is configured to: the mixer cartridge is releasably retained to the tail portion when the coupler is received into the channel in a push-fit manner prior to the tail portion receiving water from the water supply. Thus, advantageously, the mixer drum may be releasably retained relative to the tail by an O-ring without the need for a separate fastener or fastening system. In addition, the mixer barrel is advantageously connected to the tail portion and releasably retained thereto in a single continuous motion comprising connecting the coupler in a push-fit manner within the channel of the tail portion.

Detailed Description
Referring to fig. 1, a conduit assembly 10 according to a first exemplary embodiment of the present invention is shown. The conduit assembly 10 includes a tail portion 12 that may be connected to a water supply (not shown) in a manner known to those skilled in the art. The tail 12 is configured to deliver hot and cold water provided by a water supply to the mixer cartridge 14. The mixer cartridge 14 is configured to mix hot and cold water and then deliver the mixed water to an outlet of a plumbing device, such as a shower mixer tap, wall mixer tap, bowl mixer tap, or the like.
During the "rough stage" of the building construction of the dwelling, the tail is typically connected to the water supply of the dwelling. During this construction phase, the architect will also typically require the owner or resident to select the plumbing to be connected to the tail. Once the selection is made, the plumbing fixture is transported to the residence and then specific components of the plumbing fixture are installed by a skilled installer during the rough phase. In particular, the mixer drum of the pipe arrangement is sealingly connected to the tail part. The mixer drum is typically housed in a chromed mixer drum housing that can be damaged if improperly handled. The mixer barrel is connected to the tail by twisting a lock nut around the mixer barrel (or mixer barrel housing) to a specific torque setting to ensure a sealed connection between the mixer barrel and the tail. As will be explained below, one of the advantages of the present invention is that the selection and installation of particular components of the plumbing fixture may be delayed or altered until after the rough stage of construction is completed.
Referring to fig. 2, the tail 12 of the present invention includes a brass housing 16 which, when in place, is generally inverted "T" when viewed from the front. The housing 16 includes a first conduit 18 having a generally circular cross-section, the conduit 18 including a first inlet 20 at a first end of the conduit 18. The inlet 20 is configured to receive hot water from the water supply when the tail 12 is connected to the water supply. The conduit 18 also includes a second inlet 22 at a second end of the conduit 18 opposite the first end of the conduit 18. The second inlet 22 is configured to receive cold water from the water supply when the tail 12 is connected to the water supply. The housing 16 further includes a second conduit 24 having a generally circular cross-section. The second conduit 24 extends from a longitudinal midpoint of the first conduit 18 generally perpendicular to the first conduit 18. The second conduit 24 includes an outlet 26, the outlet 26 being configured to deliver mixed water provided by the mixer cartridge 14 to an outlet of a shower mixer tap (not shown) in a manner described below. In this case, "mixed water" refers to hot and cold water received via the respective hot and cold water inlets 20, 22, and the hot and cold water is mixed by the mixer drum 14.
The tail 12 further includes a generally circular face 30, the face 30 being disposed in a direction transverse to the hot water inlet 20 and the cold water inlet 22 and the outlet 26. The face 30 is recessed relative to the front circular edge 32 of the housing 16 and defines three separate fluid passages 34, 36, 38, each having a generally circular cross-section, and fluidly connected to a respective one of the hot water inlet 20, the cold water inlet 22, and the outlet 26. Specifically, the first hot water channel 34 is fluidly connected to the hot water inlet 20 and is configured to deliver hot water received via the hot water inlet 20 to the mixer cartridge 14 in a manner described in detail below. The housing 16 also includes a second cold water channel 36, the second cold water channel 36 being fluidly connected to the cold water inlet 22 and configured to deliver cold water received via the cold water inlet 22 to the mixer cartridge 14. The housing 16 further includes a third outlet passage 38, the third outlet passage 38 being fluidly connected to the mixed water outlet 26 and configured to deliver mixed water from the mixer cartridge 14 to an outlet of a shower head (not shown) via the mixed water outlet 26. The front circular edge 32 of the housing 16 defines a threaded outer surface 33.
While the tail 12 is configured to deliver mixed water to the outlet of the showerhead, it should be understood that alternative forms of tail may be used to deliver mixed water to, for example, a wall mixer tap or a bowl mixer tap. For example, fig. 3 shows a tail portion 12' according to a second embodiment of the present invention. The tail 12' includes a housing 16', which housing 16' is generally elongated in overall form. The housing 16' includes a conduit 18' having a generally circular cross-section and includes (similar to the tail 12 shown in fig. 2) a hot water inlet 20', a cold water inlet 22' and a mixed water outlet 26' that is fluidly connected to the outlet of a wall mixer or bowl mixer (not shown). The housing 16 'also includes a hot water passage 34', a cold water passage 36', and an outlet passage 38'. The hot water channel 34 'and the cold water channel 36' are configured to deliver the respective hot and cold water received from the hot water inlet 20 'and the cold water inlet 22' to the mixer drum, and the outlet channel 38 'is configured to deliver the mixed water received from the mixer drum to the outlet of the wall bathtub mixer or wall basin mixer via the mixed water outlet 26'.
Returning to the first embodiment of the tail 12 shown in FIG. 2, it can be seen that each of the fluid passages 34, 36, 38 includes an inner circumferential recess, each of which is configured to receive a corresponding sealing device. The sealing means is configured to sealingly connect the tail 12 to the mixer barrel 14 in the following manner. Furthermore, the sealing device is configured to releasably retain the mixer cartridge 14 relative to the tail portion 12 when no water is supplied to the tail portion 12 by the water supply (such as during installation of the conduit assembly 10 during a "rough stage").
In the illustrated embodiment, the hot water channel 34 includes a first inner circumferential recess 34a and a second inner circumferential recess 34b configured to receive sealing means in the form of O-rings 40a, 40b, respectively (fig. 1). Similarly, the cold water passage 36 includes first and second inner circumferential recesses 36a, 36b configured to receive O-rings 42a, 42b (FIG. 1), respectively, and the mixed water passage 38 includes first and second inner circumferential recesses 38a, 38b configured to receive O-rings 44a, 44b, respectively. The recesses in each fluid channel 34, 36, 38 are spaced apart from each other and are sized to receive a corresponding O-ring in a push-fit manner. The use of two O-rings in each fluid passage 34, 36, 38 has been found to provide an enhanced seal between the mixer barrel 14 and the tail 12.
Referring to fig. 4A and 4B, the mixer cartridge 14 is shown. As described above, the mixer cartridge 14 is configured to mix the respective hot and cold water received via the hot and cold water inlets 20, 22 of the tail 12 and then deliver the mixed water via the mixed water outlet 26 to the outlet of a shower head (not shown). The manner in which the mixer drum 14 mixes the hot water with the cold water will be known to those skilled in the art. Briefly, the mixer cartridge 14 includes a series of internally movable ceramic discs, each of which has an opening for directing hot or cold water into the mixing chamber. The ceramic disc is selectively movable by a control element 46, which control element 46 is operatively connected to a stem handle of a shower mixer faucet, as will be described later. By selectively moving the lever handle, the ratio of hot water to cold water introduced into the mixing chamber can be selectively adjusted via the control element 46. Specifically, the control element 46 moves the ceramic discs relative to each other to adjust the size of the openings of the mixing chamber, thereby adjusting the ratio of hot water to cold water delivered to the mixing chamber for mixing.
The mixer cartridge 14 according to the illustrated embodiment of the invention includes a generally cylindrical housing 48 having an internal mixing chamber. The control element 46 is arranged at an outer end of the housing 48 and extends substantially along a central longitudinal axis of the housing 48. The control element 46 is in the form of a generally elongate member having a uniform square cross-section along at least a portion of the length of the member. The control element 46 is receivable into a complementary recess of the lever handle of the shower faucet and is selectively rotated in a conventional manner from a central closed position (as shown in fig. 4A and 4B) to the left and right to control the water temperature and about a lateral axis to control the water flow rate.
The mixer cartridge 14 also includes three couplers 50, 52, 54 at the inner end of the housing 48 that are sized to be received in a push-fit manner to a respective one of the fluid passages 34, 36, 38 of the tail 12. The couplers 50, 52, 54 exhibit a generally uniform circular cross-section and include inwardly converging end portions 50a, 52a, and 54a, respectively. The mixer cartridge 14 includes a first hot water interface 50, the first hot water coupler 50 being configured to fluidly connect to the hot water channel 34 when the coupler 50 is received into the hot water channel 34 in a push-fit manner, and the first hot water coupler 50 being configured to receive hot water from the hot water inlet 20 via the hot water channel 34. The mixer cartridge 14 also includes a second cold water coupler 52, the second cold water coupler 52 being configured to fluidly connect to the cold water channel 36 when the coupler 52 is received in the cold water channel 36 in a push-fit manner, and the second cold water coupler 52 being configured to receive cold water from the cold water inlet 22 via the cold water channel. The received hot and cold water are mixed in the mixing chamber according to the position of the control element 46 and then delivered to the third outlet coupling 54. The outlet coupler 54 is configured to deliver the mixed water to the outlet 26 of the tail 12 (and ultimately to the outlet of the showerhead) via the outlet passage 38.
Advantageously, the mixer cartridge 14 is fluidly and sealingly connected to the tail portion 12 when the couplers 50, 52, and 54 are received in a push-fit manner to the respective fluid passages 34, 36, and 38 containing the respective O-rings 40a, 40b, 42a, 42b, and 44a, 44 b. As used herein, "sealingly connected" means that the mixer cartridge 14 is connected to the tail portion 12 in the following manner: such that no or substantially no fluid is leaked or lost when transferred from the tail 12 to the mixer drum 14 or from the mixer drum 14 to the tail 12.
In addition to sealingly connecting the mixer drum 14 to the tail 12 during use, the O-rings 40a, 40b, 42a, 42b, 44a and 44b releasably retain the mixer drum 14 relative to the tail 12 during installation of the plumbing assembly 10 (i.e., when no water is being delivered to the tail 12 by the water supply). Thus, advantageously, the mixer drum 14 may be releasably retained relative to the tail portion 12 during installation of the duct assembly 10 without the need for a separate fastener or fastening system. In other words, the mixer cartridge 14 is releasably retained relative to the tail portion 12 by simply push fitting the couplers 50, 52, 54 of the mixer cartridge 14 into the respective fluid passages 34, 36, 38 of the mixer cartridge 12, whereby the O-rings 40a, 40b, 42a, 42b, 44a, and 44b engage the respective couplers 50, 52, 54 of the mixer cartridge 14.
After the couplings 50, 52, 54 of the mixer cartridge 14 are push-fitted to connect with the respective fluid passages 34, 36, 38 of the tail 12, the mixer cartridge 14 may be releasably secured to the tail 12 by threadably connecting a mixer cartridge housing 78 (fig. 1) to the tail 12 about the mixer cartridge 14. As described in more detail below, the mixer cartridge housing 78 is removably received at least partially over the mixer cartridge 14 and is configured to engage the mixer cartridge 14. The mixer cartridge housing 78 includes threads that threadably connect to the threads 33 on the tail portion 12 to releasably secure the mixer cartridge 14 to the tail portion 12. Advantageously, the mixer cartridge housing 78 may be threadably connected to the tail portion 12 by rotating the mixer cartridge housing 78 relative to the tail portion 12.
The disclosed combination of the tail 12 and the mixer barrel 14 is an advance over the prior art that generally requires a skilled installer to install a locking nut around the mixer barrel (or mixer barrel housing) and twist the locking nut to a particular torque value or setting to releasably secure and sealingly connect the mixer barrel to the tail. In practice, due to the general lack of a suitable high precision hand tool, skilled installers find it difficult to reproducibly lock the lock nut to the desired torque setting to ensure a fluid seal between the mixer barrel and the tail. Advantageously, as described above, the mixer cartridge 14 of the present invention need only be connected to the tail portion 12 via the couplers 50, 52 and 54 in a push-fit manner to connect the mixer cartridge 14 to the tail portion 12 and releasably retain to the tail portion 12. Further, the mixer drum 14 may then be secured in position relative to the tail 12 by threadably connecting the mixer drum housing 78 to the tail 12 about the mixer drum 14. Advantageously, since the O-rings 40a, 40b, 42a, 42b, 44a and 44b engage the respective couplings 50, 52, 54 of the mixer drum 14, there is no need to twist the mixer drum housing 78 to a predetermined torque value minimum in order to thereby sealingly connect the mixer drum 14 to the tail 12.
In addition, push fitting the couplers 50, 52, 54 of the mixer cartridge 14 into the respective fluid passages 34, 36, 38 of the tail 12 is a relatively simple and quick method of installation between the mixer cartridge 14 and the tail 12. Moreover, the disclosed combination of the tail 12 and the mixer barrel 14 is an advance over the prior art in that the mixer barrel 14 is advantageously connected to the tail 12 and releasably retained to the mixer barrel 14 in a single continuous motion that includes the coupling 50, 52, and 54 being connected into the respective fluid passages 34, 36, and 38 in a push-fit manner.
The manner in which a skilled installer may install the conduit assembly 10 of the present invention in a residence will now be described with reference to fig. 1, 5 and 6. As explained above, the tail 12 is typically connected to a residential water supply (not shown) during the rough stage of construction. As shown in fig. 6, the tail 12 is mounted in a cavity 60 defined between a wall post 62 and a gypsum board front wall 64 of the residence and is connected to a water supply such that hot and cold water can be delivered to the respective hot and cold water inlets 20, 22 of the tail 12 as desired. Tail 12 is secured to ledge 62 by two pairs of fasteners (not shown) that are received into corresponding pairs of apertures 17 (fig. 2) in a pair of flange extensions 19 of housing 16, respectively. As shown in fig. 2, each of the flange extensions 19 extends in the general direction of the second fluid conduit 24 and is located on the rear side of the first fluid conduit 18, adjacent to the end of the conduit 18. Returning to fig. 5 and 6, it can be seen that the front wall 64 includes a cavity 66 therein of a suitable size so that an installer can access the front face 30 of the tail 12 through the front face 68 of the front wall 64.
At this stage, the test tail 12 and the supply water may be leak tested. To this end, two generally circular plugs 70 (FIG. 1) of similar size to the couplings of the mixer cartridge 14 are used to plug the hot water channel 34 and the cold water channel 36 of the portion tail 12. Each of the plugs 70 is received in a push-fit manner into a respective fluid channel 34, 36 containing a respective pair of O-rings 40a, 40b and 42a, 42b. A generally circular cap portion 72 (fig. 1) is then threadably connected around the threaded outer surface 33 of the rim 32 of the shell 16 of the tail 12. A sleeve 74 (fig. 1) having a generally circular cross-section is then inserted into the cavity 66 such that the front face of the sleeve 74 abuts the housing 16 of the tail 12, as shown in fig. 5. The sleeve 74 is configured to act as a water barrier between the duct assembly 10 and the home, and in particular is configured to prevent damage to the front wall 64 from water leakage from the tail 12. The tail 12 and water supply are then leak tested by the installer in a manner known to those skilled in the art. At this stage, the water supply may also be flushed and cleaned of debris.
After leak testing of the tail 12 and the supply water, the circular cap 72 may remain threadably connected to the housing 16 of the tail 12 until the rough stage of construction has been completed. This is an advantageous development of the prior art method for installing such a pipe assembly. As explained above, in the prior art method, during the rough stage of construction, the mixer drum and its generally delicate chrome plated housing will be sealingly connected to the tail. This provides the opportunity to subject the chromed shell to damage caused by, for example, a merchant in order to complete the construction of the house.
In the assembly (fit-off) phase of the residential construction, i.e., when installing fixtures and fittings in the residence, a skilled installer may simply remove the circular cap portion 72 and plug portion 70 and complete the installation of the pipe assembly 10 as described. Once the cap 72 is removed, the mixer cartridge 14 is fluidly and sealingly connected to the tail portion 12 and releasably retained to the tail portion 12 by push fitting the couplings 50, 52, 54 of the mixer cartridge 14 into the respective fluid passages 34, 36, 38 of the tail portion 12. An O-ring 76 (fig. 1) is then inserted into cavity 66 so that it abuts the front surface of front circular edge 32 of tail 12, as shown in fig. 5. The mixer cartridge housing 78 (fig. 1) is then threadably connected about the threaded outer surface 33 of the tail portion 12, thereby securing the mixer cartridge 14 to the tail portion 12. As shown in fig. 5 and 6, the mixer cartridge housing 78 is in the form of a sleeve and is configured to receive the mixer cartridge 14 therein. As described above, the mixer cartridge housing 78 has a chromed outer surface and includes an opening at its outer end through which the control element 46 of the mixer cartridge 14 extends. Any remaining components of the shower mixer tap are now installed. For example, the control element 46 of the mixer cartridge 14 is inserted into a complementary recess in the lever handle 80 (fig. 5 and 6) of the shower mixer faucet such that selective movement of the lever handle likewise causes movement of the control element 46 to control water temperature and flow. A face plate 82 (fig. 5 and 6) also surrounds the mixer cartridge housing 78 such that the face plate abuts the front face 68 of the front wall 64 and covers the cavity 66 and the sleeve 74 from view.
As described herein, the present invention provides a conduit assembly comprising a combination of a tail 12 and a mixer drum 14, wherein the tail 12 and the mixer drum 14 are advantageously fluidly and sealingly connected to each other by a simple push-fit arrangement. This simple push-fit arrangement also ensures that the mixer drum is releasably retained relative to the tail without the need for a separate fastener or fastening system. Thus, finally, the present invention provides a relatively simple and quick method of installing a conduit assembly.
In addition, as described above, the cover portion 72 and plug portion 70 may simply be removed from the tail portion 12 during the assembly phase of construction, and the remaining components of the plumbing device may then be installed. Thus, advantageously, the risk of damaging the delicate chrome plated exterior of the mixer drum housing 78 is greatly reduced, as the chrome plated exterior is not exposed from the rough stage of construction to the assembly stage of construction. In addition, due to this new installation method, the selection of the type of plumbing connected to tail 12 may be deferred until the assembly phase of construction. In practice, this means that the transportation of the plumbing installation to the house can be postponed until this stage of construction, which greatly reduces the risk of theft of the plumbing installation.
It will be understood that the invention disclosed and defined in this specification extends to all alternative combinations of two or more of the individual features mentioned or evident from the text or drawings. All of these different combinations constitute various alternative aspects of the invention.
