Description
BACKGROUND OF THE INVENTION
This invention relates generally to a water spraying device for use
as shower or bath fixture to provide vertical spray control.
In the past, the standard shower spray fixture allowed water to
spray from essentially one point mounted high up the shower wall.
Uniform and complete rinsing of the body is made difficult by such
mounting. Also the height of the spray fixture made showering for
short people and children difficult to adjust and unsatisfactory
for rinsing.
Applicant's invention eliminates these problems by providing a
vertically disposed spraying device to insure complete rinsing of
the entire human body from head to toe, the spraying action being
adjustable to accomodate people of all heights including small
children. It also allows a person to shower without getting his
hair wet. The device may also provide for controlling the quantity
of spray.
BRIEF DESCRIPTION OF THE INVENTION
A liquid spray control device for use as a shower or bath fixture
comprising a liquid spraying pipe closed at one end and coupled to
a liquid source, said pipe having a plurality of apertures disposed
along the axial direction of the pipe, a water-tight sleeve
coaxially disposed about the outside of the pipe, said sleeve
rotatable relative to said pipe and having cut out areas that are
circumferentially, angularly varied in size in increments along the
sleeve axial direction whereby all or only a selected portion of
the pipe apertures are exposed and uncovered by said sleeve. A
sealing flange is provided to reduce or eliminate leakage between
the pipe outer surface and the sleeve inner edges.
It is an object of this invention to provide an improved shower
spray fixture.
It is another object of this invention to provide a vertically
oriented shower spray that is variable in height.
And yet another object of this invention is to provide a variable
intensity and height spray device for liquid dispensing.
And still yet another object of this invention is to provide a
shower spray adaptable to persons of all heights that is a water
saver.
In accordance with these and other objects which will be apparent
hereinafter, the instant invention will now be described with
particular reference to the accompanying drawing.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of applicant's invention.
FIG. 2 shows applicant's invention installed in a shower unit.

invention.
PREFERRED EMBODIMENT OF THE INVENTION
FIG. 1 shows a shower device in accordance with applicant's
invention generally at 10 comprising a sleeve member 16
circumferentially disposed about a shower pipe 12 which is a tube
closed at the bottom and having a plurality of apertures 14 (not
all marked for clarity). The top portion of pipe 12 is connected to
a liquid source. The sleeve 16 has a plurality of cut out sections
18, 20, 22, and 24 cut along the circumferential and the axial
direction of the pipe, each section having a different area removed
in size such that section 18 is the smallest while section 24 is
the largest cut out area. The cut out portions 18 through 24 are
also staggered in size circumferentially about the pipe and
arranged so that end portions of the cut out sections do not lie
along a common axial line at one end. The sleeve fits snugly about
pipe 12 and is provided with a sealing flange 26 (dotted) to
prevent leakage from edges adjacent cut out portions caused from
water eminating from apertures 14 that are covered by portions of
sleeve 16. The sleeve 16 is rotateably coupled to pipe 12 about the
outside circumference of pipe 12 and is moveable circumferentially
in the directions shown by arrow A. In the position shown in FIG.
1, approximately half of the apertures 14 which provide the shower
spray are exposed through the cut out portions 22 and 24 of sleeve
16. The remaining apertures 14 are blocked by the inside surface of
sleeve 16. The appertures are disposed in rows along the axial pipe
direction. The number of rows may be of design choice dependent on
shower spray volume desired. Rotation of sleeve 16 from right to
left will expose the remaining apertures.
The device is positioned in a shower as shown in FIG. 2 to lie in a
vertical direction adjacent a shower wall surface. The length of
the shower device will be such to encompass the tallest of human
beings down to the very shortest. Thus the shower sleeve 16 in FIG.
3 may be rotated to provide a shower spray of a desired heighth
beginning from the bottom progressing all the way to the uppermost
portion of the shower spray pipe. The pipe 12 is coupled to a
normal household water supply under pressure and has a plurality of
water valves 28 for regulating temperature and turning the water on
and off. The shower is mounted by coupling pipe 12 to wall surface
31 by brackets 29 which may be bolted or made to adhere to surface
31 in a standard manner.
FIG. 3 shows flange portion 26 lying on the inside surface of
sleeve 16 which fits against exterior wall of pipe 12 to provide a
sealing joint between portions of the sleeve and the outer pipe
surface. The flange 26 is placed around the periphery of the cut
out areas. A grooved portion in the pipe 12 which could prevent
water leakage would also be effective by acting as a drain for
escaping water.
FIG. 4 shows an alternate sleeve arrangement in which the sleeve
has a plurality of individually rotatable sections 30 each having
an individual cut-out portion 31 and a grasping means 32. Each
sleeve section 30 moves independently of the others. Each may be
rotated to cover or expose apertures 14, thus providing total
vertical spray control in height. The spray volume may also be
controlled by varying the number of apertures covered with respect
to each sleeve section 30.
FIG. 5 shows an alternate sleeve configuration 34 in which the
staggered cut out areas are replaced by one large cut out area
which has parallel sides that gradually change in their
circumferential position. Again the sleeve 34 is rotatable relative
to the pipe 12. The vertical spray may be adjusted in small
increments in either direction to provide a top, total vertical, or
bottom spray.
FIG. 6 shows the sleeve 16 of FIG. 1 removed from the pipe to show
the circumferential cut out portions. Bottom portion 16A is a
circular band coupled completely about the pipe which helps attach
the sleeve 16 to pipe 12. Top portion 16B is likewise a complete
circular band.
The sleeve 16 may be of any suitable material for use as a shower
fixture such as metal, plastic or hard rubber, and would be a
matter of design preference.
Applicant's shower may be provided with a flexible coupling member
for installation to a standard single spray wall mounted shower
pipes having threaded end portions or mounted to a bath tub faucet.
The device may be permanently or portably mounted to the adjacent
wall surface.
The instant invention has been shown and described herein in what
is considered to be the most practical and preferred embodiment. It
is recognized, however, that departures may be made therefrom
within the scope of the invention and that obvious modifications
will occur to a person skilled in the art.
