DUAL SHOWER HEAD ATTACHMENT DEVICE
Abstract
An attachment device for converting a single shower head
personal shower installation or to dual, opposed shower head
installation to provide for showering from each side of the shower
enclosure or recess, is described. A rigid conduit pipe, threaded
at one end for connection with a shower installation shower water
outlet fitting at one end of the shower recess or enclosure in
substitution for the usual single shower head arm, is provided
along its length with a pair of longitudinally-spaced shower heads
and, at its outer end, is provided with adjustable thrust abutment
means for frictional engagement with the opposite wall of the
shower recess or enclosure in securing the attachment device in
place. A control valve in the path of flow to the two shower heads
provides for selective control of shower water thereto for
independent or dual use in showering.

Description
This invention relates to personal showers and is directed
particularly to a dual shower head assembly for use in substitution
for the usual single shower head assembly in personal shower
enclosures.
A more particular object of the invention is to provide a dual
shower head attachment device which, upon installation, provides a
pair of elevated shower heads spraying inwardly from each side of a
personal shower enclosure, thereby enabling two persons to shower
independently at the same time or, alternatively, one person,
standing centrally in the shower enclosure, to be showered from
each side for more rapid and effective cleansing.
Yet another object is to provide a dual shower head attachment
device that is particularly well suited to installation and use in
association with a standard bathtub by simple substitution for the
usual shower head arm pipe installed within a tub wall of the
associated tub enclosure recess.
Still another object of the invention is to provide a dual shower
head attachement device of the above nature which, at one end,
threads into the shower water outlet fitting within the wall at one
end of a bathtub enclosure and which, at the other end, is provided
with adjustable means enabling abutting thrust securement to the
opposite tub enclosure wall.
Still another object of the invention is to provide a dual shower
head attachment device of the character described which will be
simple in construction, easy to install, attractive in appearance,
light in weight, and durable and effective in use.
Other objects, features and advantages of the invention will be
apparent from the following desccription when read with reference
to the single FIGURE of the accompanying drawing, indicating, in
elevation, an ordinary bathtub and portions of its enclosure recess
and illustrating a dual shower head attachment device embodying the
invention assembled thereto.
Referring now in detail to the drawing, reference numeral 10
designates, generally, a dual shower head attachment device
embodying the invention assembled for use between the head and foot
walls 11, 12, respectively, of a bathroom tub recess R partially
surrounding a standard built-in tub T. The attachment device 10
comprises a short, externally-threaded nipple 13 at one end fitted
to and extending outwardly of a two-way flow control valve 14. The
in-line outlet port of the control valve 14 communicates with a
first co-axial length of pipe 15, which connects, through a
coupling member 16, with a second co-axial length of pipe 17. The
second length of pipe 17 connects with a T-fitting 18, the co-axial
outlet port of which is connected with a short length of pipe 19,
co-axial with the first and second lengths of pipe 15 and 17. The
short length of pipe 19, as is hereinbelow more particularly
described, serves as part of the support mechanism for the
attachment device 10 and is therefore plugged, as by a plug member
20 screw-threaded into an interior thread provided at the outer end
of said pipe. Alternatively, a solid rod could be substituted for
the length of pipe 19, thereby dispensing with the plug member 20.
Exteriorly threaded to the outer end of the short length of pipe 19
is an internally-threaded coupling member 21 into the outer end of
which is adjustably threaded a headed abutment member 22, the outer
end of which is provided with a resilient friction pad 23, such as
of hard rubber. The overall length of the attachment device 10 from
just short of the outer end of the nipple 13 and the outer end of
the friction pad 23 is approximately 5 feet, corresponding to the
distance between the opposite end walls of the recess within which
a standard bathtub is installed. The length of the coupling member
21 and its associated abutment member 22 is such as to provide
about two inches of overall length adjustment of the attachment
device 10, allowing for sufficient length adjustment to accommodate
a wide range of variation in the spacing between the end walls of
an ordinary 5' tub recess.
The perpendicular outlet ports of the two-way flow control valve 14
and the T-fitting 18 extend in the same direction and are fitted
with curved mutually inwardly-directed shower head arms 24, 25 the
outer ends of which connect with adjustable shower heads 26, 27
controlled by adjustment levers 28, 29, respectively.
In use, the usual curved shower head arm (not illustrated) of an
ordinary tub shower installation will be removed from the
internally-threaded fitting F installed within the wall 12 at the
foot of the tub, after which the nipple 13 of the attachment device
10 will be threaded in place in substituion. In order to permit
such installation of the attachment device 10 it will ordinarily
first be necessary to adjust the abutment member 22 to its
innermost position within the coupling member 21. After the
attachment device 10 has thus been securely threaded in place with
the shower heads 26 and downwardly, extending donwardly, and with
the longitudinal axis of the device extending horizontally and
substantially in the perpendicular direction with respect to the
opposing tub recess walls 11 and 12, the abutment member 23 will be
unscrewed from the coupling member 22, to extend the overall length
of the attachment device to such an extent that the friction pad 24
abuts against the tub recess wall at the head of the tub, thereby
securely wedging the attachment device in its installed position,
ready for use.
In use, the tub shower controls, (not illustrated) will be operated
in the usual manner to supply shower water to the supply fitting F,
whereupon it will flow through either one or both, selectively, of
the shower heads 26 and 27, depending upon the setting of the
control valve 14. In this connection it is to be noted that the
control valve will adjustably control flow to the shower heads so
that shower strength can be varied from strong to weak,
selectively, as well as off. The shower head adjustment levers 28,
29 serve additionally to control the flow force of their associated
shower heads 26, 27. Thus, one person can either use the dual
shower head attachment device as an ordinary single shower head
shower or, by activating both shower heads upon adjustment of the
flow control valve 14, can be showered upon from each side for more
effecient and rapid showering. In instances when two people wish to
shower independently but at the same time, such as a mother and
small child, the device is particularly advantageous.
Although the attachment device 10 can conveniently and economically
be fabricated of ordinary metal piping and fittings, such as of
copper, brass or galvanized iron, it will preferably be fabricated
of synthetic plastic material, such as of PVC piping and fittings,
for economy and lightness in weight. For shipping purposes, the
coupling member 17 will be secured to only one of its associated
pipe lengths 15 and 17 with connection being made upon
installation. If fabricated of PVC plastic material, the dual
shower head attachment device 10 could be supplied as a kit with a
tube of cement for effecting the in-line connection of the pipe
lengths 15 and 17. It is also contemplated that such a kit could be
supplied with long enough pipe lengths 15 and 17 to permit cutting
to size to fit shower enclosures of various widths.
While I have illustrated and described herein only one form in
which my invention can conveniently be embodied in practice, it is
to be understood that this form is given by way of example only,
and not in a limiting sense. The invention, in brief, comprises all
the embodiments and modifications coming within the scope and
spirit of the following claims.
