The invention relates to U.S. Pat. No. 6,807,691 issued on Oct. 26, 2004, which is incorporated herein by reference.
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.
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.
One aspect of the present invention is to provide a low cost apparatus for at least partially shielding under-sink plumbing.
A second aspect of the present invention is the design of the low cost apparatus such that the apparatus will preclude interference from the under-sink plumbing with the retractable hose.
A third aspect of the present invention is the design of the apparatus for easy installation and removal.
A fourth aspect of the present invention is the design of the apparatus such that the apparatus snaps onto a feature of the plumbing.
A fifth aspect of the present invention is a design that includes a two-piece system which can snap, be screwed together, and the like to fasten around a feature of the plumbing.
A sixth aspect of the present invention is a design such that the knob for the respective valve remains exposed to allow operation without removal of the present invention.
A seventh aspect of the present invention is the inclusion of reference markings, notch, removable feature, and the like to provide for clearances for various supply and inlet lines as well as fitting between the cabinet and the plumbing valves.
A seventh aspect of the present invention is the inclusion of a label or printed identifier used for advertisement or promotional means, such as including the contact information for a respective plumber.
An eighth aspect of the present invention is the ability to manufacture the apparatus using injection molding.
A ninth aspect of the present invention is the inclusion of a slot(s), the slots providing for cable ties as a means to couple the present invention to the under-sink plumbing.
A tenth aspect of the present invention is the inclusion of a means to secure the present invention to at least one of the cabinet or a wall.
An eleventh aspect of the present invention is to fabricate the present invention of a semi-rigid or rigid material.
A twelfth aspect of the present invention is an application or design such to reinforce or increase the rigidity of the present invention along a line of contact of the hose.
A thirteenth aspect of the present invention is a cover positioned above said valve.
A fourteenth aspect of the present invention is a cover positioned above said valve, wherein said cover is at least one of as broad as said valve and wider than said valve.
A fifteenth aspect of the present invention is a cover positioned above said valve, wherein said cover is at least one of as broad as said valve and wider than said valve, wherein said cover is tapered as follows: an edge proximate the wall is wider than an edge farthest from the wall.
A sixteenth aspect of the present invention is a cover positioned above said valve, wherein said cover comprising at least one member which protrudes below said valve for guiding said spray nozzle hose around said valve, thus avoiding any interference.
A seventeenth aspect of the present invention is a cover positioned above said valve, wherein said cover comprising at least one hose guide member which protrudes below said valve for guiding said spray nozzle hose around said valve, thus avoiding any interference, said hose guide member further comprising an aperture for routing any additional plumbing.
An eighteenth aspect of the present invention is a cover positioned above said valve, wherein said cover further comprising at least one pitch for avoiding interference with said hose during the retraction process.
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.
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.
It can be recognized that the variations of design or features for achieving the aspects of the present invention should not limit the spirit, scope or intentions of the present invention. It can be recognized that advertisements may be applied via labels, printed onto the surface, embossed on the surface, molded into the material, and the like.
The plumbing valve cover can be manufactured using injection molding processes, metal forming processes, machining processes (although they are normally cost prohibitive), and the like. The materials can be of rubber, plastic, resins, metal, or any other (preferably cost effective) material.
