SHOWER ASSEMBLIES, MOUNTING HARDWARE AND MULTI-PORT DIVERTING VALVES THEREFOR, AND METHODS OF INSTALLING
Shower assemblies, mounting hardware and multi-port diverting valves therefor, and methods of installing rain showerhead assemblies. The show assemblies include a bracket assembly that secures to the wall and/or to the ceiling and a rain showerhead assembly supported by the bracket assembly. The bracket assembly reduces off-axis forces against the shower wall and thereby minimizes damage to the shower wall. The bracket assembly may be used to mount a wall-mounted rain showerhead assembly or a ceiling-mounted rain showerhead assembly. A shower arm three-port diverting valve or a shower arm four-port diverting valve may be used with any one of the shower assemblies.
This application claims the benefit of U.S. Provisional Application Nos. 63/341,678 filed May 13, 2022, and 63/368,709 filed Jul. 18, 2022, the contents of which are incorporated herein by reference.
BACKGROUND OF THE INVENTIONThe invention generally relates to shower assemblies and components, such as showerhead assemblies having rain-type showerheads, mounting hardware and multi-port diverting valves therefor, and methods of installing the same.
Rain-type showerheads (or more simply, rain showerheads) are so called because the showerhead is disposed directly above the shower space so that the water streams from the showerhead to travel substantially vertically downward onto a person taking the shower, giving the person the sensation that they are being rained on. Typically, rain showerheads, when installed in a new home, are piped into a permanent position (for example, the center of a shower space) from above the shower stall or tub ceiling. Alternatively, retrofitting a ceiling type rain showerhead to an already existing tub or shower stall is commonly done, for example, by a homeowner when it is desired to change the original wall showerhead to a rain showerhead.
One way to retrofit a ceiling type rain showerhead to an already existing tub or shower stall is by changing out an existing showerhead arm from the water pipe stub (i.e., the water pipe to which the showerhead is attached) that extends out from a wall such as a valve and piping wall, with a much longer, rising arm. These longer, rising arms are designed to position a rain showerhead up closer to the ceiling and farther away from the valve wall to give the person taking the shower the feeling they are getting rained on as they would if they had a new home installation straight down from the ceiling. Retrofitting a rain showerhead in this manner with a long and rising arm relies significantly on the shower arm fitting behind the wall to carry the weight of the extended arm and a typically much larger and much heavier rain showerhead. However, this installation may not always be safe and secure. For example, simply installing a larger rain showerhead using a longer shower arm can be a problem with heavier showerheads because the shower arm and/or threads can break due to the added weight and/or moment forces caused by the longer arm. In addition, the plumbing pipes and fittings can break under the additional force. Such an arrangement may need additional support. Furthermore, unless the arm support had blocking installed prior to trim, the flange would be attached to drywall only, creating a situation in which the drywall is likely to fail over time.
Another way of retrofitting a rain showerhead into an already existing tub or shower stall is to extend a bar, like a curtain rod, for example, from one side wall of the shower to the opposite side wall and then to hang the rain showerhead from this bar. Like the previous example, this rain showerhead can also be fed water from the old showerhead location with a hose or piping. This support relies on the rod having a friction fit to the side walls or being screwed to the drywall or tiled walls. The addition of or retrofitting a rain showerhead to an existing shower stall may not always be safe or secure. Further, both of these installations for retrofitting a rain showerhead to an existing shower stall may limit possible positioning of the rain showerhead and/or be limited by the weight of the rain showerhead.
Various methods and installation arrangements for retrofitting a rain showerhead to an existing wall showerhead are known. U.S. Patent Application Publication No. 2006/0236451 and U.S. Patent Application Publication No. 2015/0089734 disclose showerheads that hang from a bar and are connected to the water pipe extending from the piping wall. U.S. Pat. No. 5,022,103 discloses a shower with a long rising arm extending from a piping wall of the shower. However, these arrangements may still be subject to one or more of the drawbacks identified above.
Therefore, it would be desirable if large, heavy ceiling-type rain showerheads could be installed into an already existing tub or shower stall in a safe and secure manner.
BRIEF SUMMARY OF THE INVENTIONThe intent of this section of the specification is to briefly indicate the nature and substance of the invention, as opposed to an exhaustive statement of all subject matter and aspects of the invention. Therefore, while this section identifies subject matter recited in the claims, additional subject matter and aspects relating to the invention are set forth in other sections of the specification, particularly the detailed description, as well as any drawings.

All such relative terms are useful to describe the illustrated embodiment(s) but should not be otherwise interpreted as limiting the scope of the invention.
Turning now to the nonlimiting embodiments represented in the drawings,
The swing-out rain showerhead assembly 38 includes two connected pipe segments that swing horizontally to allow the rain showerhead 32 to be pivoted substantially horizontally at a pre-selected height across a large area of the shower stall. The first pipe segment is connected at a first end to a vertical pipe with a pivot fitting so as to pivot substantially horizontally about the vertical pipe when the piping assembly 28 is installed vertically on the shower stall wall 34. The second pipe segment is connected at a first end to the second end of the first pipe segment with a second pivot fitting so as to pivot substantially horizontally about the second pivot fitting. In this manner, the two pipe segments form a swing-out piping assembly 28 that can swing the rain showerhead 32 horizontally about a large area of the shower stall. The showerhead assembly 38 may include one or more leveling rods 52 and leveling nuts 54 configured to support the cantilevered pipe segments. The leveling nuts 54 can be adjusted, for example by rotating, to adjust the length of the respective leveling rods 52. In this way, the swing-out piping assembly 28 can be adjusted so that the rain showerhead 32 pivots in a substantially horizontal plane above the floor (not shown) of the shower stall.
The bracket assembly 36 includes a bracket mounting plate 40 that engages against the shower wall 34. One or more posts 42 extend outwardly from one side of the bracket mounting plate 40, and the opposite side of the bracket mounting plate 40 is substantially flat to engage against the shower wall 34 (or any finishes, such as tile, on the wall 34). The bracket mounting plate 40 is mounted to the shower wall 34 with one or more flanged fasteners 44 (as nonlimiting examples, lag screws, lag bolts, or wood screws) and a threaded nut 46 (e.g., a lock nut) threaded onto the exposed end of each fastener 44 to clamp the bracket mounting plate 40 between the flange of the fastener 44 and the nut 46. The fasteners 44 each have a nose portion for threading into a support structure of the wall 34, illustrated in
A shower valve and suitable conduit connect the shower assembly 30 to a water supply pipe stub 56 (

When the shower assembly 30 (or any of the other shower assemblies disclosed herein) is implemented with either the shower arm three-port diverter valve 60 or the shower arm four-port diverter valve 62, a person in the shower stall is able to both shower in the standard showering area, for example under the rain showerhead 32 and/or the third showerhead 66, and also is able to use of the handheld showerhead 64, either simultaneously or alternatingly or in any of the various combinations allowed by the respective rotary valves 72 and 92. Further, because each of the diverter valves 60 and 62 has an additional outlet port, such as the top outlet port 76, each of the diverter valves 60 and 62 allows water to be fed to the rain showerhead hanging bracket portion of the shower assembly from a commonly installed water pipe stub 56 without requiring significant reconfiguration of the water supply piping in the piping wall 34.
