P00/011 Regulation 3.2 AUSTRALIA Patents Act 1990 COMPLETE SPECIFICATION INNOVATION PATENT Invention Title: Wall-mounted valve having adjustable spout angle The following statement is a full description of this invention, Including the best method of performing it known to us: WALL-MOUNTED VALVE HAVING ADJUSTABLE SPOUT ANGLE BACKGROUND OF THE INVENTION 5 1. Field of the Invention The present invention relates to a wall-mounted valve with adjustable spout angle and particularly to a wall-mounted valve with fast adjustable spout angle to facilitate installation and use. 2. Description of the Prior Art 10 A conventional wall-mounted valve 1, referring to FIG. 1, mainly includes a body 10 with a wall-mounted section I1 at one end formed an internal thread section 111 and a spout 12 on a lateral side, and a handle 14 at another end of the body 10 to control opening and closing of a valve stem 13 to deliver water through the spout 12 or connecting to a pipe through the 15 spout. Such a structure has a big drawback, i.e. when the wall-mounted section 11 is mounted onto a wall W the final fastening position cannot guarantee the spout 12 be located in a desired direction (referring to FIG. 2). In the event that a deviation happens the entire set has to be disassembled and adjustment for the correct direction has to be made. Hence installation is 20 troublesome and time-consuming. Although a great deal of effort has been invested in the industry trying to fix this problem, there is still room for improvement. Reference to any prior art in the specification is not, and should not be taken as, an acknowledgment or any form of suggestion that this prior art 25 forms part of the common general knowledge in Australia or any other jurisdiction or that this prior art could reasonably be expected to be ascertained, understood and regarded as relevant by a person skilled in the art.
SUMMARY OF THE INVENTION Therefore it would be desirable to provide a wall-mounted valve with fast adjustable spout angle to facilitate installation and use. 5 In one aspect the present invention provides a wall-mounted valve having adjustable spout angle, comprising at least a wall-mounted member, a body and a fastening hub, wherein: the wall-mounted member includes a fastening portion at one side, a flange at another side and a bore inside formed in a multiple-step manner, the bore at the fastening portion having a 10 first internal thread section; the body includes a through hole which has a second internal thread section and a step bore at one side, the step bore being coupled with the flange of the wall-mounted member; the body further having a spout on a lateral side and a set screw hole on another side to receive a set screw to butt and anchor on the flange; and the fastening hub 15 includes an opening which has a head end at one end held in the bore of the wall-mounted member and another end formed an external thread section running through the bore of the wall-mounted member to fasten to the second internal thread section of the body. The fastening portion of the wall-mounted member may extend from an 20 outer side to form a hood. The external thread section of the fastening hub may be wedged by at least one stem washer. The body may have a third internal thread section to fasten a water control means. 25 Some embodiments of the invention include a wall-mounted member, a body and a fastening hub. The fastening hub has a head end held in a bore of the wall-mounted member and an external thread section fastened to an internal screw bore of the body. The fastening hub and the body can be turned at the same time to adjust the spout to a desired direction, then a set 2 screw can be fastened in a set screw hole formed on the body to butt and anchor on a flange of the wall-mounted member. Therefore when the wall-mounted member is installed onto a wall the spout of the body can be positioned in a desired direction. Installation and use are simpler. 5 The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 3 and 4, the present invention aims to provide a wall-mounted valve 3 which comprises at least a wall-mounted member 31, a body 32 and a fastening hub 33. 25 The wall-mounted member 31 has a fastening portion 311 at one side and a flange 312 at another side, and a bore 313 inside formed in a multiple step manner. The bore 313 at the fastening portion 311 also has a first 3 internal thread section 314. The body 32 includes a through hole 320 which has a second internal thread section 325 and a step bore 326 of a larger diameter at one side. The step bore 326 is coupled with the flange 312 of the wall-mounted member 31. 5 The body 32 further has a spout 321 on a lateral side and a set screw hole 322 at another side adjacent to the spout 321 to receive a set screw 323 to butt and anchor on the flange 312. The fastening hub 33 has an opening 332 which has a distal end formed a polygonal opening 331 and a head end 330 at one end formed at a greater 10 diameter to be held in the bore 313 of the wall-mounted member 31, and another end formed an external thread section 333 running through the bore 313 to fasten to the second internal thread section 325 of the body 32. The external thread section 333 also is wedged by at least one stem washer 334. The through hole 320 of the body 32 further has a third thread section 15 324 at another side to fasten a water control means 34. The water control means 34 includes a valve stem 341, a stem holder 342, a bonnet 343 and a handle 344. The stem holder 342 has a fastening thread 342a to fasten to the third thread section 324. Through the handle 344 a spindle 342b on the stem holder 342 can be driven to control opening and closing of the valve stem 20 341 to start or stop water supply (such a structure and technique are known in the art and form no part of the invention, thus details are omitted). By means of the elements set forth above (referring to FIG. 4), for assembly and installation, first, have the fastening hub 33 run through the bore 313 of the wall-mounted member 31 with the external thread section 25 333 fastened to the second internal thread section 325 of the body 32; next, for installation, have the first internal thread section 314 of the wall-mounted member 31 fastened to an external thread section 21 of a pipe 2 embedded in a wall W; regardless the final fastening position, the body 32 can be turned to adjust the spout 321 to a required direction (referring to FIG. 5); then fasten 30 the set screw 323 in the set screw hole 322 to butt and anchor on the wall-mounted member 31 to position the adjusted spout 321 as desired. 4 Refer to FIG. 6 for another embodiment of the invention. The body 32' does not contain water control means. Operation and control of water supply are performed through two handles 34' and 35' at two sides of a wall-mounted valve 3' (referring to FIG. 9). The wall-mounted valve 3' 5 comprises a wall-mounted member 31', a body 32' and a fastening hub 33'. Coupling of the fastening hub 33' and the wall-mounted member 31' and body 32' is substantially same as that shown in FIG. 4. The wall-mounted member 31' has a fastening portion 311' extended from an outer side to form a hood 315' to cover a construction hole formed on the wall W after the 10 wall-mounted valve 3' and the pipe 2 are coupled to serve ornamental purpose. For assembly and installation, first, have the fastening hub 33' has an external thread section 333' run through a bore 313' of the wall-mounted member 3 1' to fasten to a second internal thread section 325' formed on the body 32'; then a the flange 312' of the wall-mounted member 31' is held in a 15 step bore 326' of the body 32' to finish assembly of the wall-mounted valve 3'. For installing the wall-mounted valve 3' on the pipe 2 of the wall W, fasten the first internal thread section 314' of the wall-mounted member 31' to the external thread section 21 of the pipe 2. Thus regardless the final fastening position the body 32' can be turned to adjust the spout 321' to a 20 required direction (referring to FIG. 8); then fasten the set screw 323' in the set screw hole 322' to butt and anchor on the wall-mounted member 31' to position the adjusted spout 321' as desired. As a conclusion, the wall-mounted valve with adjustable spout angle of the invention allows the spout angle to be adjusted as desired. Assembly and 25 installation on the wall is easier. It provides a significant improvement over the conventional technique. 5
