Referring first to FIG. 1, the kit of the invention is comprised of a fixture trim 20, an adaptor 30, a bushing 80, a washer 90, a handle 100, an interchangeable adaptor element 110, and a vapor barrier gasket 140. It is to be understood that the kit of the invention is used for mounting the fixture trim 20 via handle 100 with bushing 80, adaptor 30 with washer 90 and optionally vapor barrier gasket 140, and interchangeable adaptor element 110 to plumbing hardware H, H or H, such as a wall water valve. Examples of water valves which may be used in conjunction with the industrial plumbing fixture adaptor kit of the invention may be all brands, such as, for example, those manufactured by companies, such as, MOEN, PRICE-PFISTER, KOHLER, and DELTA. As is standard, the water valve has a stem and a water conduit for delivering water into a pipe (not shown) which is attached to the pipe connector 22 of fixture trim 20 (FIG. 1). It is to be understood that an adaptor 30 is illustrated in both FIG. 1 and FIG. 2; however adaptor 30 of FIG. 1 is structured slightly different from that of adaptor 30 of FIG. 2. Nevertheless the adaptors 30 of FIGS. 1 and 2 function in a similar manner, more of which is explained further herein below.

(7) With particular reference to FIGS. 2 and 4, adaptor 30 of the industrial plumbing fixture adaptor kit of the invention has an adaptor body 32 with a first end 34 and a second end 36. External threads 40 are provided on adaptor body 32 adjacent to the first end 34. A conical element 50 is mounted on adaptor body 32 adjacent to its second end 36 at a location spaced away from the first end 34 of adaptor body 32 of adaptor 30. A hollow tube 60, having a first end 62 and a second end 64, is fixedly attached to the second end 36 of adaptor 30 adjacent to conical element 50 of adaptor 30. Hollow tube 60 is preferably rectangular in cross-section, is linearly aligned with adaptor body 32 of adaptor 30, and has an opening 66 defined at its second end 64.

(8) The industrial plumbing fixture adaptor kit of the invention further comprises bushing 80 which is mountable on the adaptor body 31 of adaptor 30 adjacent to conical element 50. As shown in FIG. 1, bushing 80 is generally in the form of a circular member with external threads. Even though not shown, handle 100 has internal threads which engage with threads 40 of adaptor 30. That is, adaptor 30 receives bushing 80 between conical element 50 and the external threads 40 of adaptor 30. A first isolater washer 90 is mounted on adaptor body 31 and against conical element between conical element 50 and first end 34 of adaptor 30. Bushing 80 allows handle 100 fixedly attached to adaptor 30 to rotate freely within fixture trim 20, as will become apparent to one skilled in the art from the teaching of this disclosure. In assembling some of the components of the kit of the invention and with reference to FIGS. 1, 2 and 3, the steps comprise: 1) mounting a first isolater washer 90 onto adaptor body 32 of adaptor 30 and against conical element 50 on the side of adaptor 30 with threads 40; 2) mounting bushing 80 on adaptor body 32 of adaptor 30 in a manner to receive handle 100; 3) mounting vapor barrier gasket 140 onto adaptor 30 and against bushing 80; 4) mounting second isolater washer 90 on adaptor 30 and against vapor barrier gasket 140; and 5) screwing handle 100 onto threads 40 of adaptor 30 such as to construct the assemblage of components as shown in a lower portion of FIG. 1. It can be appreciated that this assemblage of handle 100 within bushing 80 allows handle 100 along with adaptor 30 to rotate freely with fixture trim 20 with hollow tube 60 extending outwardly from bushing 80.

(9) As stated herein above and with reference to FIG. 1, handle 100 has internal threads (not shown) for engaging with the external threads 40 of adaptor body 32 of adaptor 30 for controlling the wall water valve or plumbing hardware, such as that indicated by reference letters H, H, and H in FIG. 2.

(10) With particular reference to FIGS. 2 and 4, the interchangeable adaptor element 110 has a first end 112 which is received in opening 66 of hollow tube 60 of adaptor 30 and a second end 114 with a tip or head 116. Interchangeable adaptor element 110 has a rectangular cross-section corresponding to that of hollow tube 60 of adaptor 30. Head 116 is fixedly mounted to interchangeable adaptor element 110 and has an opening (not shown) for receiving and engaging the plumbing hardware H of FIG. 2. As can be seen, both head 116 and plumbing hardware H have a rectangular cross-section for engagement with each other for operation of the plumbing hardware H or water valve, more about which is discussed further herein below. Still referring to FIG. 2, the attachment of head 116 to plumbing hardware H is done via a set screw 115.

(11) The kit of the invention further comprises a plurality of interchangeable adaptor elements 110, 110 each having a predetermined length. That is, as shown in FIG. 3, an interchangeable adaptor element 110 is illustrated with a length L and a head 116. It is to be appreciated that several such interchangeable elements 110 will be provided in the kit of the invention with the length L of each interchangeable element 110 varying in accordance with its application and the depth of the wall in which the water valve is located. It is also to be appreciated that the configuration of each head 116 of each interchangeable adaptor element 110 will vary according to the configuration of the plumbing hardware or water valve. That is, head 116 may have an opening for connection with a valve stem or mixing valve having the configuration of the plumbing hardware H or H of FIG. 2.

(12) As stated in the preceding paragraph, while two interchangeable elements 110, 110 are shown in FIGS. 2 and 3, respectively, it is understood that the kit of the invention supplies several such interchangeable elements of varying lengths without departing from the scope of the disclosure or the claims associated therewith. Additionally, while heads 116, 116 are shown in FIGS. 2 and 3, respectively, it is to be understood that there may be provided several such different sized heads and/or heads with different opening having varying configurations without departing from the scope of the disclosure or the claims associated therewith. The shape of heads 116, 116 may be polygonal as shown in FIGS. 2 and 3, or they may be spherical or any other shape that coincides with the valve stem or mixing valve of the plumbing hardware in which the kit of the invention is used.

(13) Referring again to FIG. 1, fixture trim element 20 is structured to be connected to handle 100. That is, fixture trim element 20 has internal threads 22 and the bushing 80 on handle 100 has corresponding external threads 102 for engagement with the internal threads 22 of fixture trim element 20 for connection of the handle 100 and adaptor 30 to fixture trim element 20.

(14) It is to be appreciated that the adaptor 30 in FIG. 1 is slightly different in structure compared to adaptor 30 of FIGS. 2 and 4; however, either adaptor 30 of FIGS. 1, 2 and 3 may be provided and used in the invention. It is to be further appreciated that the upper portion 22 of fixture trim 20 of FIG. 1 is connected to a vertical pipe which, in turn, is connected to a horizontal pipe having an end with a shower head for delivering water downwardly into the shower stall or tub.

(15) As discussed herein above, in operation of adaptor 30 with interchangeable adaptor element 110, the following steps will occur: i) head 116 of interchangeable adaptor element 110 is fixedly connected via set screw 115 to the stem of water valve or plumbing hardware H; ii) fixture trim 20 via screws (not shown) is mounted against a wall surface in alignment with the water valve of plumbing hardware H such that the rectangular member of interchangeable adaptor element 110 protrudes out of fixture trim 20; iii) the handle assembly 100 with bushing 80, vapor barrier gasket 140 and second washer 90 as shown in a lower portion of FIG. 1 is screwed via the threads of bushing 80 into the internal threads 26 of fixture trim 20 with the rectangular hollow tube 60 receiving the rectangular member of interchangeable adaptor element 110 thereby allowing the stem of the water valve (H) to turn in a direction to open the water valve via the handle assembly of FIG. 1 or to turn in an opposite direction to close the water valve via the handle assembly of FIG. 1.
