Description
ADJUSTABLE SHOWER ARM ASSEMBLY
BACKGROUND OF THE INVENTION
Field of Invention The present invention relates to shower arm assemblies, and in particular, to shower arm assemblies that can be adjusted to the desired orientation independent of the connections between the shower arm assemblies and the water supply pipes.
BACKGROUND OF THE INVENTION
Field of Invention The present invention relates to shower arm assemblies, and in particular, to shower arm assemblies that can be adjusted to the desired orientation independent of the connections between the shower arm assemblies and the water supply pipes.
2. Description of Related Art Shower arms are well known bathroom fixtures that extend outward from a water supply pipe located in a wall to supply water from the water supply pipe to a shower head (not shown) attached to the free end of the shower arm. As shown in Figs. 5 and 6, a conventional shower arm 200 is a one-piece construction having an inlet end 202 that attaches to the water supply pipe, a body 204, an outlet end 206 and a bore 208. The bore 208 extends through the body 204 from the inlet end 202 to the outlet end 206.
The inlet end 202 typically includes a male threaded portion that threadedly engages a female fitting of the water supply pipe, within the wall. The body 204 is slightly bent to project water flowing through the bore 208 downward when the shower arm 200 is installed in its proper orientation. The outlet end 206 includes a male threaded portion to threadedly engage a shower head or other downstream fixture.
In a typical installation, a shoulder 210 of the shower arm 200 abuts the wall when the shower arm 200 is fixedly attached to the water supply pipe.
Specifically, during installation, an installer rotates the shower arm 200 to engage the male threaded portion of the inlet end 202 with the stationary fitting (in this case, a female fitting) within the wall. As stated, the outlet end 206 of the properly installed shower arm should be oriented to point directly downward when the installation is complete.
The installer may reach the desired tightness between the inlet end 202 of the shower arm 200 and the wall fitting while the outlet end is not pointed directly downward. If so, the installer may be forced to rotate the shower arm 200 clockwise (i.e., thereby overtightening the connection) or counterclockwise (i.e., thereby loosening the connection and causing it to be a loose connection until the shower arm 200 is in the desired orientation).
An overtightened connection between the shower arm and the wall fitting can lead to cracks in the wall material (e.g., tile). Also, the overtightened connection may be difficult to loosen in the future if the shower arm must be serviced, maintained or replaced, or the water supply pipe accessed.
A relatively loose connection between the shower arm and the water supply pipe may lead to water leaks. Also, there may be undesirable play and/or an undesirable gap between the shoulder 210 and the wall surface adjacent the shoulder 210. Such play may cause undesirable noise and/or wear due to contact between the shoulder 210 and the adjacent wall surface when water supplied through the shower arm 200 is initiated or terminated. Also, water may leak into the gap between the wall and the shoulder 210.
Accordingly, it is desirable to provide a shower arm construction that would allow an installer to achieve the optimum tightness between the inlet end of the shower arm and the water supply pipe, yet still permit the installer to adjust the 1 S orientation of the outlet end. Stated differently, it is desirable to have a shower arm assembly wherein the orientation of the shower arm assembly is independent of the shower arm assembly/water supply pipe connection.
SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
As shown in Figs. 1-4, certain embodiments of a shower arm assembly, shower-arm assembly 10, of the present invention include a fixed conduit 12 and an adjustable conduit 14. The fixed conduit 12 is attached to the water supply pipe to the proper tightness, and the adjustable conduit 14 is then attached to the fixed conduit 12 after being adjusted to the desired orientation, as discussed below.
The fixed conduit 12 includes an inlet end 16, a shaft 18, an outlet end 23 and a bore 24 extending between the inlet end 16 and the outlet end 23. The inlet end 16 is designed to be attached to a standard water supply pipe commonly used to supply water to shower assemblies.
In the illustrated embodiment, the inlet end 16 includes a male threaded portion for threadedly engaging a corresponding female fitting in the water supply pipe. Of course, the inlet end 16 could be configured differently (e.g., with a female
4 threaded portion) depending upon the corresponding wall fitting with which the inlet end 16 is designed to engage.
The shaft 18 bears at least one seal 20 disposed within a groove in the shaft to seal the connection between the fixed conduit 12 and the adjustable conduit when the fixed conduit 12 and the adjustable conduit 14 are secured together.
[Globe-Union - please confirm] In the illustrated embodiment, two seals 20 that are spaced from each other along the shaft 18 are used.
The outlet end 23 preferably includes one or more pairs of opposing flat surfaces 22. The installer can engage the flat surfaces 22 with a tool (e.g., pliers or a wrench) if the fixed conduit 12 must be rotated to properly engage the water supply pipe.
The adjustable conduit 14 includes a shoulder end 26, a body 34, an outlet end 32 and a bore 38 extending from the shoulder end 26 to the outlet end 32. In the illustrated embodiment, the body 34 includes a set screw bore 28 that can receive a set screw 30.
The adjustable conduit 14 is installed by fitting the adjustable conduit 14 over the installed fixed conduit 12, rotating the adjustable conduit 14 to its proper orientation relative to the fixed conduit 12, and tightening the set screw 30 to secure the adjustable conduit 14 to the fixed conduit 12. Of course, any other known means or mechanisms for fixedly attaching the adjustable conduit 14 to the fixed conduit 12 can be employed instead of the set screw 30.
The body 34 includes a bent portion 36. As stated, the bent portion is normally oriented 36 so that water flowing through the shower arm 10 exits in a directly downward direction. The outlet end 32 may include a threaded portion as illustrated to receive, e.g., a shower head or other fixture.
When the adjustable conduit 14 and the installed fixed conduit 12 are assembled, the bore 24 of the fixed conduit 12 and the bore 38 of the adjustable conduit 14 form a passage for water to be supplied from the water supply pipe to the outlet end 32. The seals 20 prevent water from traveling in a reverse direction toward the shoulder end 26 between the fixed conduit 12 and the adjustable conduit 14 (e.g., by capillary action). [Globe-Union - please confirm]
The adjustable conduit 14 is adjustable with respect to the fixed conduit 12 in two ways. First, the adjustable conduit 14 can be rotatably adjusted relative to the fixed conduit 12 as discussed above. Second, the adjustable conduit 14 can be longitudinally adjusted relative to the fixed conduit 12. Stated differently, the adjustable conduit 14 can slide longitudinally along fixed conduit 12 until the desired combined length is obtained and/or until shoulder end 26 abuts the wall e.g., to accommodate different wall fitting-to-outside wall surface distances, to accommodate additional conduits (e.g., a ring) between the wall surface and the shoulder end 26, etc.
The fixed conduit 12 and the adjustable conduit 14 are preferably made of metal, although other suitable materials such as plastics (e.g., PVC) may also be used.
Although the connection between the inlet end 16 of the fixed conduit 12 has been described above as a threaded connection, the present invention also pertains to applications with an inlet end that is attached to the wall fitting without threads (e.g., by brazing or bonding).
Although this invention is described in conjunction with its specific embodiments thereof, many alternatives, modifications and variations will be apparent 1 S to those skilled in the art. Accordingly, the preferred embodiments of the invention as set forth above are intended to be illustrative, not limited. Various changes to the invention may be made without departing from its true spirit and scope as defined in the following claims.
