## Abstract

A plumbing valve cover is disclosed for use in conjunction with under-sink plumbing to avoid interference with the operation of a flexible spray nozzle hose used in conjunction with a spray nozzle. The plumbing valve cover may be coupled to the under-sink plumbing or cabinet wall. The plumbing valve cover may partially cover the under-sink plumbing and include clearances for multiple plumbing lines which may exit a supply valve via either the top, bottom, or sides. The preferred embodiment would be a single piece, injection molded plastic apparatus comprising a horizontal member which covers the top of the valve and two vertical members. The vertical members would be angled or curved to redirect the flexible hose away from getting caught on the valve. The horizontal member can include a pitch to redirect the hose away from the cover or valve when the hose is being retracted into the cabinet.

## Background
RELATED U.S. PATENT APPLICATIONS
The invention relates to U.S. Pat. No. 6,807,691 issued on Oct. 26, 2004, which is incorporated herein by reference.
FIELD OF THE INVENTION
This invention relates in general to the field of under-sink plumbing valve covers, and in particular to a plumbing valve cover which is placed about an under-sink supply valve or similar object wherein such object may interfere with the operation of a spray nozzle and associated flexible, movable hose, generally used in conjunction with a kitchen sink.
BACKGROUND OF THE INVENTION
Sinks or washbasins may include a spray nozzle or water dispenser which is attached to a flexible hose, where the flexible hose retracts into an opening and is stored freely under the sink. A weight or spring may be attached to the hose to assist in retracting the hose into the opening and improve storage control of the flexible hose under the sink. The hose generally is provided through an opening on the side/rear of the sink (Side Spray), or through an opening in the center of a faucet (Pullout faucet).
Water supply lines enter from the wall, pass through an opening in a cabinet and are coupled to a valve. A supply line exits the valve and connects to a faucet control such that the user can turn the water on and off. It is recognized that there may be hot and cold water lines, as well as multiple inlet lines exiting from each valve for other appliances such as refrigerators or dish washing machines.
The supply line is normally horizontal which may be the optimal orientation for installing the cabinets. The valve generally has an oval shaped handle. The handle is generally larger than the water supply line. The orientation of the plumbing and the handle on the valve creates a scenario that can interfere with the movement of the loose hose. It can be seen that a hose of sufficient length can loop below the horizontal water supply line or lines and become entrapped. This may preclude the spray nozzle from fully deploying and hindering operation or even render the nozzle useless.
Spray nozzle hoses normally comprise a weight to assist in drawing the hose back, below the sink, referred to as a retraction step herein. The hose can get caught on top of an object during the retraction step.
Hertz (U.S. Pat. No. 6,807,691)(Issued to the present Inventor) defines a design that is optimal to a valve that is parallel with a supply line. Plumbing installations can further comprise two valves positioned perpendicular to said supply line.
Thus, what is necessary is a low cost and efficient apparatus for avoiding the interference between the retractable hose and the plumbing and valves that provides for broad applications.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 illustrates an isometric view of a sink 10 mounted within a cabinet 12 to illustrate the need for the present invention. A faucet 14 and faucet handles 16 are generally mounted through holes located in either the sink 10 or the top of the cabinet 12. A spray nozzle 18 may be accessed through a flexible hose opening 22 located adjacent to the faucet 14 or through a flexible hose opening in the faucet 14 (not shown in that configuration). The spray nozzle 18 is coupled to an exit end of a flexible hose 20 with an inlet end of the flexible hose 20 coupled to the plumbing (not shown) to provide water (not shown) to the spray nozzle 18. There are many methods known to couple the hose to each fixture. The water is provided to the system through supply line plumbing 24, a supply line valve 26 and inlet line plumbing 30, normally one for cold water and a second for hot water. The supply line valve 26 may be designed in various configurations. The supply line valve 26 is illustrated in an angled configuration, where the supply valve handle 28 would be located in front of the plumbing. Alternatively, supply line valves 26 may be configured as a through valve where the supply valve handle 28 is located on the top of the valve. The supply line valve 26 may be configured to include one or more connections for outputs to provide for inlet lines 30 to the sink or other appliances. The water drains through a P-Trap 32 which has a first end of the P-Trap 32 is coupled to a drain (not shown) located at the bottom of the bowl of the sink 10 and a second end of the P-Trap 32 is coupled to a sewage line (not shown) generally located at the back of the cabinet.
It can be recognized from the illustration that the under-sink plumbing comprising supply line plumbing 24, supply line valve(s) 26, and supply line valve handle(s) 28 would interfere with the flexible hose 20 when the flexible hose 20 is pulled through the flexible hose opening 22 by the user.
The figure is provided to illustrate a general arrangement of plumbing located under a sink, where the plumbing includes a spray nozzle 18 coupled to the flexible hose 20.
FIG. 2 is an enlarged section of the isometric view of FIG. 1 including the present invention installed according to a preferred embodiment. In accordance with the preferred embodiment of the present invention, a plumbing valve cover 40 is mechanically coupled to a cabinet rear wall 38 via at least one plumbing valve cover mount 42. It can be recognized that there are many other methods of securing said plumbing valve cover 40 into position such as a pipe clamp around the supply valve 26, secured by a snap feature, screws, and the like. It should be recognized that the method of installation should not limit the present invention.
The function of the plumbing valve cover is exhibited by the illustration whereby the design of the plumbing valve cover 40 allows at least one of the flexible hose 20 and flexible hose weight 34 to ride against the plumbing valve cover 40 thus avoiding interference between the lower service loop of the flexible hose 20 and the supply valve 26, supply valve handle 28, and other such plumbing. This will be described in more detail below. In the present state, as the flexible hose 20 is pulled through the flexible hose opening 22, the plumbing would interfere with the lower service loop created by the geometry of the flexible hose 20. The inclusion of the present invention provides a hose deflector (lower member) whereby when the service loop created in the flexible hose 20 rides against the hose deflector of the plumbing valve cover 40; the flexible hose 20 would not be caught in the plumbing. The bottom of the plumbing valve cover 40 is designed such that when the flexible hose 20 is pulled upwards through the flexible hose opening 22, the lower service loop rides along the hose deflector of the plumbing valve cover 40 and moves in front of the supply valve 26, supply valve handle 28, and associated plumbing thus avoiding any interference. Further, by adding a pitch to the upper surface of the plumbing valve cover 40, the flexible hose 20 rides to the side of the plumbing valve cover 40 when the flexible hose 20 is retracted into the flexible hose opening 22.
FIG. 3 is a cross-sectional view of the plumbing valve cover 40 further illustrating the resulting motion of the flexible hose 20 respective to the plumbing valve cover 40 as the flexible hose 20 is lifted through the flexible hose opening 22. The supply valve assembly 26 includes a supply line connector 44 for coupling the supply valve 26 to the supply line plumbing 24, a valve to sink inlet line connector 46 for coupling the supply valve 26 to the inlet line plumbing 30 and the supply line valve handle 28. The shape of the supply valve 26 provides ample locations for mechanically coupling the plumbing valve cover 40, using any of known mechanical coupling methods such as a plumbing valve cover mount 42 which, in one embodiment, comprising a flange style mount as shown. The plumbing valve cover 40 would be shaped in a manner to provide for the flexible hose 20 to move along a flexible hose directing path 50 when being raised through the flexible hose opening 22 by the user. In accordance with the illustrated embodiment, said plumbing valve cover 40 comprising a generally horizontal member 78 which is designed to span across said supply valve 26 and at least one generally vertical member 82 protruding downward from said generally horizontal member. Although said generally horizontal member 78 is described as horizontal, it is recognized that by defining said generally horizontal member 78 as “generally”, any shape to span across the width of the valve would be considered within the spirit and intent of the present invention. Said generally vertical member is designed to direct the flexible hose 20 from catching on said supply valve 26. The plumbing valve cover 40 may further include a plumbing aperture section 52 whereby additional plumbing which may exit the sides (shown later herein) of the supply valve 26. The clearance may be included in the design as shown or of removable sections. Such removable sections may include scribe lines, precut sections, and the like to simplify the removal process.
FIG. 4 is a cross sectional view of the present invention as in FIG. 3 including a free body diagram illustrating the forces which move the flexible hose 20 to avoid interfering with the plumbing. When the user lifts the flexible hose 20 through the flexible hose opening 22, the hose introduces a user-applied force 60. The user-applied force 60 is composed of a normal force 62 and a tangential force 64. The tangential force 64 moves the flexible hose 20 in a manner to avoid interference with the plumbing. The illustration further introduces an accessory supply line(s) 48 shown exiting through said plumbing aperture section 52. The illustration presents a proposed flexible hose directing path 50 providing a detail where the flexible hose 20 would move around the supply line valve handle 28, should the design allow the supply line valve handle 28 to protrude slightly. Said plumbing valve cover 40 is installed by fastening said plumbing valve cover 40 to said cabinet rear wall 38.
