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. a
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.
Applicants 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 applicants invention.
FIG. 2 shows applicants invention installed in a shower unit.
FIG. 3 is across-sectional elevation of the sealing groove in Applicants'invention.
FIG. 4 is an alternatesleeve embodiment of applicants invention.
FIG. 5 is an alternate sleeve embodiment of applicantsinvention.
FIG. 6 shows an alternate sleeve in accordance with applicant's invention.
PREFERRED EMBODIMENT OF THE INVENTION FIG. 1 shows a shower device in accordance with applicants 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 out 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.
FlG. 6 shows the sleeve 16 of FIG. I 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 168 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.
Applicants 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.
What I claim is:
1. A shower fixture for controlling liquid spray length comprising:
a tube having an open end for receiving liquid and a closed end and a plurality of apertures aligned along the tube axis; and
a plurality of sleeve members, individually rotatable about said tube, disposed circumferentially about said tube, each sleeve member having an aperture portion, moveable to expose a portion of said tube apertures, for controlling the volume of spray.
2. A shower fixture mountable on a wall comprising:
an enclosed tube vertically mounted on said wall, said tubing having a plurality of relatively small apertures disposed in a relatively narrow column longitudinally along said tube, facing substantially away from said wall surface, said tube having a water inlet coupleable to a source of water under pressure;
a sleeve circumferentially disposed adjacent to said first tube outer surface, said sleeve rotatable circumferentially with respect to said first tube, said sleeve having a longitudinally elongated aperture, said sleeve aperture substantially equal in length to said tube aperture column and varying in width incrementally in the sleeve circumferential direction from a relatively narrow width adjacent one end of said sleeve to a relatively wide width adjacent the opposite end of said sleeve, the narrow sleeve aperture width being substantially the tube aperture column width with one side of said sleeve aperture being parallel to the longitudinal axis of said sleeve.
3. A shower fixture as in claim 2, wherein: said sleeve aperture width expands from the narrow width to the wide width in a helical pattern.
