Title: Rough-in assembly for free-standing faucet

Description:
BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present invention relates to a rough-in assembly, especially to a rough-in assembly able to be mounted under a floor and used for mounting a free-standing faucet. 
     Description of Related Art 
     A typical free-standing faucet is disposed on a floor around a tub for filling water into the tab. Refer to U.S. Pat. No. 9,334,633, a tub filler faucet assembly for coupling to a floor is revealed. The tub filler faucet assembly includes a free-standing spout spaced apart from a tub wall; a valve assembly fluidly coupled to the spout; a free-standing mounting assembly spaced apart from the tub wall and coupled to the spout and a top surface of the floor; and a rough-in assembly positioned below the floor and coupled to the free-standing mounting assembly. The rough-in assembly includes at least one passageway fluidly coupled to the valve assembly. 
     The rough-in assembly further includes a cold-water inlet tube, a hot-water inlet tube, a base and a cover that conceals the inlet tubes and a portion of the base. At least a part of the rough-in assembly is positioned below the floor while other portions of the rough-in assembly are protruding from the floor. 
     After reviewing technical documents, the rough-in assembly generally includes a single base or two bases. The single base has two water supply ports connected to a cold-water supply pipe and a hot-water supply pipe correspondingly. If there are two bases in the rough-in assembly, each of the bases is provided with a water supply port while the water supply port of one of the bases is connected to the cold-water supply pipe and the water supply port of the other base is connected to the hot-water supply pipe. A first alignment plate and a second alignment plate are disposed between the two bases to keep a preset distance between the two bases. However, no matter single-base or double-base, the base is usually made from metals such as copper-based metals so that the bases produced have the shortcoming of too much weight. 
     Moreover, the water supply port is located at a specific position of the single base. Yet the water supply pipes for cold water and hot water can be arranged in a variety of ways. For example, the hot-water ad cold-water supply pipes are in line with or perpendicular to each other. Sometimes the water supply pipes for cold water and hot water may be disposed on weird positions with specific angles between them due to limitations caused by the surrounding environment or space. Now the base with the water supply port at the specific position doesn&#39;t meet the requirement of the pipe arrangement. As to the rough-in assembly with two bases, it is mainly adapted for use in the design with two trim members, not suitable for the design with single trim member. The respective trim members are designed to be disposed on certain positions and having certain distances therebetween so that trim tubes mounted therein for connection to a cold water inlet tube and a hot water inlet tube respectively also need to be arranged at certain positions with certain distances therebetween. Thereby the above rough-in assembly with two bases is only applied to one kind of water supply pipe arrangement, without being widely used in different water supply pipe arrangements. 
     Furthermore, the above base is connected to the bottom surface of the floor by fasteners. But such connection may cause irreparable damages to the floor. The above free-standing mounting assembly includes at least one trim member and a mounting plate connected to the trim member. The mounting plate is connected to cylindrical openings of the base by fasteners for clamping and positioning the floor firmly. That is to say, the floor is clamped and pressed by both the mounting plate and the base. At the same, the total weight of the filler faucet assembly composed of the base and the free-standing mounting assembly acts on the floor. The rough-in assembly with such design has at least two problems. The first one is that under certain conditions, installers are easy to over-tighten the fasteners in order to connect the base and free-standing mounting assembly firmly. A certain area of the floor being clamped is unable to take the load and thus getting damaged to have dents and deformation therearound. Or the structural strength of the floor is low and thus easy to have dents and deformation. The second problem is that the floor itself can&#39;t stand the weight of the filler faucet assembly even the fasteners are properly torqued. The dents and deformation still show. 
     Refer to Chinese Patent. Pub. No. CN110042886A, a mounting base for floor bathtub faucets is revealed. The mounting base has similar problems. For example, two water inlets arranged at a base of the mounting base are designed to have certain positions and directions. Thus the mounting base is only adapted for use in one kind of water supply pipe arrangement. A positioning member is formed by the bottom of an outer part and a positioning flange which allows the positioning member to insert in is formed on the base. There is only the positioning mechanism provided, without disclosing any fastening mechanism. Thereby whether the outer part is firmly secured on the base of the mounting base is uncertain. 
     SUMMARY OF THE INVENTION

Each of the first lugs  25  and each of the second lugs  35  are provided with a first insertion hole  251  and a second insertion hole  351  respectively. The base  10  is arranged with four connecting holes  12  which are divided into two sets. By two sets of two fasteners  26 ,  36  inserted through the first insertion holes  251  on the first lugs  25  and the second insertion holes  351  on the second lugs  35  and secured in the respective sets of the connecting holes  12  respectively, the first water-contact member  20  and the second water-contact member  30  are connected to and fixed on the base  10 . The fasteners  26 ,  36  can be common bolts and the connecting holes  12  are threaded holes. 
     In this embodiment, the rough-in assembly  100  further includes two air caps  70  used for being plugged into the first outlet end  42  of the first connection pipe  40  and the second outlet end  52  of the second connection pipe  50  correspondingly for sealing. 
     As shown in  FIG. 9 , in this embodiment, the rough-in assembly  100  further includes a protective cover  80  whose bottom is well mounted in the mounting hole a 3  of the floor a so as to cover and protect the first connection pipe  40 , the second connection pipe  50 , the first control valve set  24  of the first water-contact member  20  and the second control valve set  34  of the second water-contact member  30  arranged relative to the mounting hole a 3 . The arrangement of the protective cover  80  is the same as the conventional one, mainly used to prevent dust and other foreign matter generated during installation from entering the rough-in assembly  100  through the respective pipes, holes or gaps and further avoid the effects of the dust and other foreign matter on normal operation of the rough-in assembly  100 . It should be noted that the protective cover  80  is mounted to and fixed on an inner wall of the mounting hole a 3  by tight fit, instead of being fastened on one of the components. Or the protective cover  80  is directly abutting against and supported by certain positions of the first water-contact member  20  and the second water-contact member  30 . Thereby the protective cover  80  can be detached and removed quickly after the installation of the rough-in assembly  100  being completed, without using any removal tools. 
     The installation of the rough-in assembly  100  of the present invention has the following steps. 
     First, the base  10 , the first water-contact member  20 , the second water-contact member  30 , the first connection pipe  40 , the second connection pipe  50 , and the sleeve mounting seat  60  are assembled with one another. The assembly process can be done either at the site or before packaging of the product. 
     Then the base  10  is fastened on the support board b 1  of the connecting wall b prepared in advance. Meanwhile, the first water supply pipe d 1  is connected to the first water-contact member  20  and the second water supply pipe d 2  is connected to the second water-contact member  30 . Later perform water testing and air testing of the respective pipelines of the rough-in assembly  100  to ensure no leakage. 
     Next the floor a and the protective cover  80  are placed in turn and other construction work is carried on. 
     After other construction work being completed, the protective cover  80  and the air cap  70  are removed. The first outlet end  42  of the first connection pipe  40  and the second outlet end  52  of the second connection pipe  50  are mounted and positioned in the first flow pipe  4   a  and the second flow pipe  4   b  of the inlet tube set  4  of the free-standing faucet  1  respectively. Then the fixing baseplate  8  is fastened on the top plate portion  61  of the sleeve mounting seat  60  while the sealing plate  6  is abutting against and pressed on the top surface of the floor a around the mounting hole a 3  for covering the mounting hole a 3  by the second bolts  9   b  that fasten the sealing plate  6  on the fixing baseplate  8 . Later the decorative cover  7  is placed over the sealing plate  6 . Thereby the free-standing faucet  1  is installed and fixed on the floor a quickly by the rough-in assembly  100  and the installation of the free-standing faucet  1  is completed. 
     Refer to  FIG. 10 ,  FIG. 11 , and  FIG. 12 , another embodiment is revealed. The difference between this embodiment and the above one is in that an ange 1 θ 2  formed between the first central axis X 1  in the opening direction of the first water inlet  21  of the first water-contact member  20  and the second central axis X 2  in the opening direction of the second water inlet  31  of the second water-contact member  30  in this embodiment is in the range of 90 degrees to 270 degrees (as shown in  FIG. 13 ) while the angle θ 1  of the above embodiment is limited to 180 degrees. In other words, compared with the first embodiment, the angle θ 2  of this embodiment is adjustable in the range of 90 degrees to 270 degrees, not limited to 180 degrees. For example, the positions and the directions of both the first water-contact member  20  and the second water-contact member  30  can be adjusted at the same time. Or one of the first and the second water-contact members  20 ,  30  is fixed while the position and the direction of the other water-contact members  20 ,  30  are adjustable. 
     In this embodiment, the first water-contact member  20  whose direction and position are nonadjustable is fixed on the base  10   a  and the second water-contact member  30  whose direction and position are adjustable is connected to the base  10   a  so as to adjust and control the angle θ 2 . A feasible approach is that the angle θ 2  can be 90 degrees, 180 degrees or 270 degrees. To go a step further, generally water supply pipes that supply cold and hot water such as the first water supply pipe d 1  and the second water supply pipe d 2  have already been arranged before installation of the free-standing faucet  1 . Thereby the rough-in assembly  100  can be applied to the water supply pipes commonly arranged perpendicular to or in line with each other when the angle θ 2  is 90 degrees, 180 degrees, or 270 degrees as mentioned above. 
     In this embodiment, as shown in  FIG. 12 , two first connecting holes  13  and at least six second connecting holes  14  are disposed on the base  10   a . Two of the second connecting holes  14  form a set so that the second connecting holes  14  are divided into a first set  14   a  of the second connecting holes  14 , a second set  14   b  of the second connecting holes  14  and a third set  14   c  of the second connecting holes  14 . The first water-contact member  20  is fixed on the base  10   a  by two fasteners  26  being inserted through respective first insertion holes  251  on respective first lugs  25  and secured in the respective first connecting holes  13 . The second water-contact member  30  is connected to the base  10   a  by two fasteners  36  being inserted through respective second insertion holes  351  on respective second lugs  35  and selectively locked in one of the three sets  14   a ,  14   b , and  14   c  of the second connecting holes  14 . The angle θ 2  is 90 degrees, 180 degrees, and 270 degrees when the fasteners  36  are connected to the first set  14   a  of the second connecting holes  14 , the second set  14   b  of the second connecting holes  14  and the third set  14   c  of the second connecting holes  14  respectively. 
     It should be noted that the centers of the second connecting holes  14  are all located at a circumference of an imaginary circle while the center of the imaginary circle is located at the central axis of the second water outlet  32  of the second water-contact member  30 . Thereby the position of the second water outlet  32  remains the same no matter how the second water-contact member  30  is adjusted. The relative position of the first connection pipe  40  to the second connection pipe  50  is further ensured. That means the assembly of the second connection pipe  50  with the second flow pipe  4   b  will not be affected. 
     It should be understood easily that whether the second water-contact member  30  or the second water supply pipe d 2  connected to the second water-contact member  30  can be inserted through the sleeve mounting seat  60   a  smoothly should be considered in order to avoid interference with the second water-contact member  30  when the position and the direction of the second water-contact member  30  are adjustable. Thus a through hole  621  is disposed on each of the side plate portions  62   a  of the sleeve mounting seat  60   a . Thereby the second water supply pipe d 2  is connected to the second water inlet  31  of the second water-contact member  30  through one of the opposite openings  641  or one of the opposite through holes  621 . For example, the second water supply pipe d 2  is connected to the second water inlet  31  of the second water-contact member  30  through one of the opposite openings  641  while the second water-contact member  30  is disposed on the position where the angle θ 2  formed is 180 degrees. The second water supply pipe d 2  is connected to the second water inlet  31  of the second water-contact member  30  through one of the opposite through holes  621  when the angle θ 2  formed between the first water-contact member  20  and the second water-contact member  30  is 90 degrees or 270 degrees. 
     It should be noted that the second water inlet  31  of the second water-contact member  30  can be designed to be located at an inner side of the side plate portion  62 . At the moment, the second water supply pipe d 2  is inserted through the opening  641  or the through hole  621  to be connected to the second water inlet  31 . Or the second water inlet  31  can be designed to be protruding from the opening  641  or the through hole  621 , located at an outer side of the side plate portion  62 . This is beneficial to the assembly of the second water supply pipe d 2  with the second water inlet  31 . 
     Moreover, due to limitation caused by the side plate portion  62 , the second water inlet  31  or the second water supply pipe d 2  may have interference with the corresponding side plate portion  62  while the second water-contact member  30  is arranged at certain positions with specific angle θ 2 . Thus the present rough-in assembly  100  may be unable to be used at certain specific angles θ 2  between 90 degrees and 270 degrees. However, the rough-in assembly  100  can be applied as long as there is no interference. Thereby the rough-in assembly is much more applicable. 
     Furthermore, one of the first hollow-out holes  611  on the top plate portion  61  of the sleeve mounting seat  60  corresponding to the second control valve set  34  is designed into a curved slot. Thereby the second control valve set  34  is able to be kept within the curved slot or even allowed to be extending out above the curved slot, without affecting operation and control performed by installers during installation when the angle θ 2  is adjusted in the range of 90 degrees to 270 degrees. 
     The installation steps of this embodiment of the rough-in assembly  100  are similar to those of the above embodiment and the only difference between the two embodiments is in that: whether the position and the direction of the second water-contact member  30  being assembled need to be adjusted in advance according to positions and directions of the first water supply pipe d 1  and the second water supply pipe d 2  is checked firstly. Once it is confirmed that the adjustment is necessary, the installer needs to check whether the sleeve mounting seat  60   a  needs to be detached, depending on the actual conditions. If the sleeve mounting seat  60   a  needs to be detached in advance, put it back after the first water-contact member  20  and the second water-contact member  30  being assembled with the first water supply pipe d 1  and the second water supply pipe d 2  respectively and the base  10  being fastened on the support board b 1 . 
     In summary, the rough-in assembly  100  of the present invention has the following features and functions: firstly the rough-in assembly  100  includes two separate water-contact members, the second water-contact member  20  and the second water-contact member  30 . The position and the direction of at least one of the water-contact members are adjustable according to actual arrangement of the water supply pipes. For example, the rough-in assembly  100  can be used for installation of the water supply pipes usually arranged in line with each other (at an angle of 180 degrees), perpendicular to each other (at an angle of 90 or 270 degrees), or with a specific angle therebetween (an angle ranging from 90 to 270 degrees). Thereby the rough-in assembly  100  can be widely adapted for use in different water supply pipe arrangements. Therefore not only the cost for mold making and material preparation is reduced, the ease of installation is also enhanced. Secondly the free-standing faucet  1  can be installed and fixed directly by the arrangement of the sleeve mounting seat  60 . Compared with the conventional technique by which the free-standing faucet  1  is directly clamped and fastened on the floor, the problem of the floor that is easy to have dents or deformation can be solved. There are no worries about either damages to the floor caused by the dents and deformation or whether the structural strength of the floor made of specific material and thickness is able to bear the clamping force or the total weight of the free-standing faucet  1  and the rough-in assembly  100 . Thereby free-standing faucet  1  is securely firmly, without being wobbly while being touched or contacted. The dent and deformation problems of the floor a can be avoided to improve the aesthetic appearance.
