Abstract
A modular shower arm mounting system includes a water conduit and a replaceable shower arm assembly in sealing engagement therewith. The water conduit has a generally uniform inner wall and an outer diameter wall having a hexagonally or polygonally shaped drive force receiving area adjacent a threaded area. The conduit has one end attached to a manifold behind a shower wall surface and an outlet end projecting from the wall surface of sufficient length therefrom so that the drive force receiving area and threaded area are spaced from the wall surface. The replaceable shower arm assembly has an inner wall with a threaded portion for engagement with the conduit and a substantially smooth portion of gradually decreasing inner diameter downstream of said threaded portion approaching an outwardly projecting end thereof. The seal ring is adjacent the outlet end of the conduit to form a seal with the assembly. The shower arm assembly is replaceable without disconnecting the conduit from the manifold thereby allowing the user to easily change the shape and/or color of the visible shower arm assembly.
Description
FIELD OF THE INVENTION
The present invention relates to a modular mounting system for plumbing fixtures such as shower arms. In prior art shower arm mounting systems, there may a shower arm which serves to support and position the shower head, but conventionally there may be an undesirable degree of difficulty in removing the shower arm when the user wants to change the style or color of bathroom fixtures. A principal problem with current shower arm assemblies is that there is no way for the user to replace the visible portion of the assembly without disconnecting a manifold attached to the shower riser inside a wall. Thus, people desiring to enhance the aesthetic style of their bathroom fixtures cannot remove the entire visible portion of the shower arm without great difficulty.
The present invention provides a modular shower arm mounting system which supports the shower arm assembly and allows for replacement of the visible portion of the shower arm assembly without requiring disconnection of the manifold or causing water to leak behind the wall. Thus, the user may remove the old assembly and replace it with a new assembly which has a more desirable style.
SUMMARY OF THE INVENTION
The present invention relates to a shower arm mounting system.
A primary purpose of the invention is to provide a modular shower arm mounting system a portion of which is replaceable without the difficulty associated with disconnecting parts from behind the wall so that the user may easily replace the shower arm assembly.
Another purpose of the invention is to provide a replaceable shower arm assembly which forms all or a substantial part of the visible portion of the modular shower arm mounting system.
Another purpose of the invention is to provide a replacement shower arm assembly which avoids potential water leakage from occurring behind the shower wall.
Another purpose of the invention is a modular shower arm mounting system as described which provides for a firm mounting of the replaceable shower arm assembly.
Other purposes will appear in the ensuing specification, drawings and claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The present invention relates to a modular shower arm mounting system which provides for the replacement of the visible portions of the shower assembly. The invention further provides for the replacement of the shower arm assembly without requiring any disconnections behind the shower wall to minimize water leakage.
In FIG.
1
and
FIG. 2
, the modular shower arm mounting system
10
includes a water conduit
12
, a replaceable shower arm assembly
14
and an O-ring
16
.
The water conduit
12
has a generally uniform inner diameter
18
and an outer diameter
20
with a hexagonally shaped portion
22
adjacent a threaded area
24
. The conduit
12
has one end
26
threadably attached to a manifold behind the shower wall
27
and an outlet end
28
projecting from the wall
27
a sufficient distance such that the hexagonally shaped portion
22
and threaded portion
24
are spaced away from the wall
27
. The conduit
12
is connected to the manifold and thus provides a firm support for the visible elements of the shower assembly.
FIG. 3
shows the hexagonally or polygonally shaped portion
22
which serves as a drive or tool engaging surface to allow the conduit
12
to be tightened to the manifold. The threaded area
24
provides for threaded engagement with the replaceable shower arm assembly
14
.
It is preferred that all or a substantial portion of the conduit
12
which projects from the wall be located within the replaceable shower arm assembly
14
so that only the replaceable elements are visible. It is also preferred that the threaded portion
24
of the conduit be located adjacent the wall with the hexagonally shaped portion
22
being located adjacent and downstream thereof so that in assembly the replaceable shower arm assembly
14
passes over the hexagonally shaped portion
22
and threadably engages the threaded portion
24
.
The replaceable shower arm assembly
14
has an inner wall
30
which has both a threaded portion
32
and a substantially smooth portion
34
. The outer diameter
36
of the assembly
14
gradually decreases from adjacent the wall
27
toward an outwardly projecting end
38
. The threaded portion
32
of the inner wall
30
is several times longer than the threaded portion
24
of the conduit
12
so that the shower arm assembly
14
may be continually tightened on the conduit
12
until the shower arm assembly is adjacent the wall with the shower arm assembly forming all or substantially all of the visible portion of the mounting system
10
. The substantially smooth portion
34
of the inner wall
30
gradually decreases downstream of the threaded portion
32
as the inner wall approaches the outwardly projecting threaded end
38
. A portion of the outwardly projecting end
38
may be angled down with respect to the rest of the shower arm assembly
14
so that projecting end is directed towards the user. As shown in
FIG. 1
, the projecting end
38
may threadably mount a shower head shown in phantom.
The O-ring
16
is adjacent the outlet end
28
of the conduit
12
and is positioned in an appropriately sized groove
40
to form a seal between the assembly
14
and the conduit
12
.
Because all or a substantial portion of the conduit
12
which projects beyond the wall is positioned within the replaceable shower arm assembly
14
, a user desiring to change the appearance of the fixture need only replace the shower arm assembly
14
. The assembly
14
is configured for easy and convenient removal so that the style and/or color of the shower arm may be conveniently changed by the user without the complication associated with behind the wall connections. The user merely threadably removes the old shower arm assembly without disconnecting the conduit from the manifold. Then the new shower arm assembly with the desired aesthetics and a similar threadable configuration to the old shower arm assembly is engaged with the conduit until the shower arm assembly is adjacent the wall. Thus, the visible portion of the modular shower arm mounting system may be replaced with any style that is desired by the user.
Whereas the preferred form of the invention has been shown and described herein, it should be realized that there may be many modifications, substitutions and alterations thereto.
