Field of Invention
[0001] 1. Short Description
[0002] A lightweight, less then 10 Lbs. non ceramic urinal, which hangs on two wall brackets. It comes with a water supply line connected to a push type flush valve with auto shutoff, delivering 15 ounces of flushing water or 5 times the amount of drain pipe trap liquid of 3 ounces. This urinal develops no urinating sounds, splash or splatter from any of it's parts. The urinal receiving bowl has an elongated drain pipe connecting to a soil pipe trap and drain line which connects to a fitting set into a drilled hole in the side of the toilet giving access to the toilets internal drain pipe system or the drain line can be connected directly into any soil pipe.
[0003] 2. Applies to Previous Inventions
[0004] Although this inventions function is related to those before it, that is where this it's invention improvements begin. It is in the most simple, familiar design and uncomplicated construction containing significant and unique elements of improvements that make it capable of outperforming all previous urinals and financially accessible to the mass population throughout the world, even in our struggling economies. This invention addresses all of the known problems that has existed since the first urinal was made, some one hundred and fifty years ago. Listed here are the ten known problems and complaints that this invention addresses and ultimately corrects. #1. The waste of fresh water. #2. High cost of present urinals and flush valves. #3. Expensive installation. #4. Maintenance. #5. Urine contamination around urinals, allowing bacteria to develop and putting health at risk. #6. Splattering and splashing or urine on those urinating #7. Odors that permeates the surrounding air. #8. Cost on average, the use of many light bulbs used to illuminate a bathroom and many are to often left on. #9. The sound of someone urinating followed by the loud flushing of many gallons of fresh water for only a few ounces of urine. #10. Many a woman has screamed out over the years “WHO LEFT THE SEAT UP”?, even this most beloved question can now be put to rest.
Field of Invention
[0005] This invention is better understood by reference to the drawing. The principal of splash elimination by the use of concave and receding surfaces has been proven effective and useful in other plumbing fixtures that receive a liquid stream such as sinks, drinking fountains and to some degree urinals and toilets. Urinals and toilets have always been the exception; do to splashing, as proven by the many patents that have been filled over the years in an effort to avoid the “splash”. These two fixtures have always had a receptor cavity which used a “liquid receiving surface”; however, it is not only required in a toilet but understood due to the solid human waste that is deposited into the toilet. In the urinal, that “liquid receiving surface”; however, is not required and is the main or primary cause of splash onto the walls of the urinal itself, the floor and surrounding area of the fixture and many times back onto the person using the urinal. Thus by removing the “liquid receiving surface” by lowering the water trap well below the bowl and out of reach of any urine stream, removes the mail cause while maintaining the soil pipe water seal in the trap that is still visible to the user as required by many plumbing codes. The hydraulic vacuum suction of the draining fluids from the trap will be thus mitigated due to the urinal drain pipe connection with the soil pipe through the toilet base and use of it's vent pipe. After the initial flush, the residual water sheet will replenish the water seal in the trap.
Background
[0006] The human body must rid itself of body fluids in the form of urine. This urine is accumulated in the bladder where it is stored, stretching it's elastic like walls until the bladder sends a signal to the brain that it has attained “full” status. While the bladder has been receiving this urine it has been expanding and forcing the walls to stretch. This stretching in turn continues to create an increased pressure on the urine which is being held in check by the squeezing of the urinary tube which is surrounded by the stronger muscle of the prostate gland. When the brain receives the signal from the bladder that it is “full” it in turn sends a signal to the prostate gland to release or relax the pressure on the urinary tube allowing the urine; under pressure, to pass through the urinary tube located in the male penis. The wall of urinary tube in the penis expands as the pressurized urine enters it and flows toward the outlet or head of the penis where it is expelled by the bladder pressure. As the bladder pressure is reduced and the urine flow is diminished, the prostate again increases it's pressure on the urinary tube as that bladder empties itself. The bladder is again ready to accept urine which will again be kept in check as the prostate muscle again squeezes the urinary tube and the process starts all over again. Due to the released amount of urine and the reduction in bladder pressure to expel the last of the urine, the walls of the urinary tube and the muscles of the penis puts the squeeze on any remaining urine and empties the urinary tube. The urine; having been expelled from the end of the urinary tube, which has now lost it's bladder pressure is pushed from the head of the penis and into space where it is immediately effected by atmospheric pressure and forcing it to create an arc from the end of the penis down to the urinal surface below. This stream of urine, upon leaving the end of the penis is in many instances fractured due to the unevenness of the penis opening and may create several fractures due to the solid stream along with many droplets breaking away from the perimeter of those fractured streams and are known as “splatter”. These streams and droplets under atmospheric pressure are being forced down into a resistance such as a flat bottom of the urinal bowl, a flat metal strainer, a somewhat flat rubber or plastic screen or an accumulated amount of water whose purpose is to create a soil pipe gas liquid seal in the urinal trap. many of these conditions have been occurring for the last 150 years plus and has been the reason for the noisy sound of one urinating with splash and splatter of urine toilet seats, rims and floors. These basic same basic problems still occur today today. In order to control the flow of these fractured and splatter streams of urine, one must make the receiving surface compatible rather then harsh. The Home Urinal accomplishes to an acceptable degree that has never been reached before due to it's special designs. 12 FIG. 1 Using a receding and deep and descending surface from under and inside the top lip of the urinal bowl 13 FIG. 1 down towards the deep oversized elliptical cone whose inside vertical sides 15 FIG. 1 leads into the drain line 19 FIG. 1 where the drain line converges with the soil pipe 41 FIG. 4 into and through the toilet drain pip connections. 38 FIG. 4 This is where there are two drain pipe type connections available 39 FIGS. 4 and 43 FIG. 5 the first one is where a hole is wet drilled in the toilet base wall on either side or the rear just above the base plate and and a fluid type coupling means is installed 39 FIG. 4 for joining the urinal drain lines to the toilets internal sewage pipe.38 FIG. 4 The second method is to have the drain line connected directly into the toilet threaded drain pipe adapter fitting. 43 FIG. 5 Others would be to connect directly into a septic tank or other type of drain field application. This invention deals with those previous indicated problems by making these following improvements. Some of which are, #1 The least amount of fresh water required per flush in the industry of 15 ounces whose flush valve is quiet and takes only 4 seconds to operate. 25 FIG. 2 #2 A no splash, no splatter quiet urinal. 1 FIG. 1 #3 Newly designed angular surface of the receptacle bowl combining to develop an elongated drain pipe. 16 FIG. 1 Although this urinal drain pipe is elongated, it does not negate the person from seeing the liquid in the trap at it's base which is required by some plumbing codes. 17 FIG. 1 Within the same elongated drain pipe 16 FIG. 1 the urine stream angle which is much lower then the visual angle, will not allow the urine stream to directly impinge on the liquid in the trap 17 FIG. 1 therefor no splash or splatter can transpire. #4 The relocation of the drain pipe trap 17 FIG. 1 along with joining the drain line with the toilet internal sewage pipe 34 FIG. 4 and 42 FIG. 5 Along with Along with these improvements the Home Urinal comes with all the hardware required to install it within most bathrooms. This includes the fresh water line 7 FIG. 1 and compression fittings, the “T” fittings and internal flush lines 23 and 27 FIG. 2 secured by the “U” bolt and mounted flush valve, battery operated Motion Detector 36 FIG. 3 and two LED light bulbs and batteries, 37 FIG. 3 inc. batteries, two wall fasteners, 10 FIG. 1 drain pipes 19 FIG. 1 Ells and couplings along with chemicals and instructions. There is a lightweight cover or lid on the urinal 32 FIG. 3 much like any toilet tank lid. The flush valve 25 FIG. 2 protrudes up through the center of the lid 34 FIG. 3 for easy access along with a decal 35 FIG. 3 on the front of the lid indicating “FAUCET SHUTS OFF AUTOMATICALLY”. There is also a hole in the front center 33 FIG. 3 where the Motion Detector sensor “eye” 36 FIG. 3 fits flush with the front lip of the lid. The sensor will activate when someone enters a darkened bathroom or at night. The sensor illumination is from two small LED lifetime light bulbs 37 FIG. 3 battery powered and bright enough to do almost anything in the bathroom, it will remain on for two minutes after one leaves the bathroom giving a soft glow back to their room. This is a safety factor for the young, old and everyone in between because when one leaves a illuminated room into a dark hallway or bedroom, one must wait until our vision adjust to the darkness. The urinal top 32 FIG. 3 is very lightweight and also removable to make any service adjustments which may become necessary, such as battery changes every two years. The entire urinal weighs less then ten pounds and hangs on the wall using two supplied wall hangers 10 FIG. 1 The Home Urinal is easy to install and operate, easy to clean with brush supplied and service if necessary. It also eliminates that female question “WHO LEFT THE SEAT UP” once and for all as males will no longer be required to lift the seat on a toilet to urinate. It is “Whisper Quiet” in operation both for urinating and for flushing. The total cost of the total cost of the complete kit will be less then one third of those on the market today. It should have a return on investment of only 2 years, saving you money and a 1,000 gallons of fresh water per month per male person for many years to come. Installation can be done by a Do-It-Yourself person or by a plumber in less then 4 hours. The walls and floor need not be disturbed and the inch and a quarter drain pipe meets plumbing code with no electric required.

Claims
1. Claim we make:
A non-ceramic male urinal fabricated of Polymeric material having a modern designed receptical bowl. This bowl comprising of three characteristic unique areas. The transition from a receptacle bowl with internal peripheral surface angles converging into a cone with an oblong circumference narrowing vertically into a drain pipe rendering and the absence of any liquids. A water supply line connected to a four second operating flush valve whose outlet flushing lines supply water to a upper section of the rear wall. There are two flushing lines located within the side walls terminating into holes just below the horizontal water control rim of the receptacle bowl. These flushing lines supply water which is directed around the underside of the water control rim where gravity forces it downward along the internal surface of the urinal bow. This water and urine will confluent downward through the outlet drain region of the receptacle bowl. This drain region was formed into the lower section of the receptacle bowl by the convergence of all it's internal peripheral surface angles and converging into a continuous outlet drain pipe. This outlet drain pipe connects into a trap which maintains a liquid seal. The purpose of the liquid seal is to seal off the soil pipe gases from entering the receptacle bowl drain pipe. The water and urine confluent as gravity transfers these fluids from the drain pipe through the trap and out of it's discharge end into the drain pipe which converges with the soil pipe. The connection to the soil pipe can be completed through many difference ways. One is to connect the the drain line into a fitting which has been placed into a wet drilled hole in a standard toilet wall base leading into the internal drain pipe of the toilet. The second way is to use a special toilet with a threaded external drain pipe connection, whereby a threaded fitting would be inserted. A third way is to connect directly into the soil pipe using a saddle type connector. There are many other ways to make a soil pipe connection by using any any water appliance drain pipe or to any septic system. This Home Urinal is a non-ceramic urinal made of Polymeric material, is light weight and hangs on two wall hangers, much like a picture frame. It uses only 15 ounces of water, which is less then the E.P.A. requirements and does it through a 4 second flush valve quietly while a dark bathroom is illuminated via motion sensor for safety with a 2 minute delay, allowing one time to return to their room with a soft light glow. The light weight urinal lid is removable; much like a toilet tank lid, for any type of servicing.
2. A urinal unit as claimed in claim 1 comprising of a removable top for servicing.
3. A urinal unit as claimed in claim 2 whereas the removable top has an offset hole in the top surface allowing the flush valve activator to protrude up through the lid.
4. A urinal unit as claimed in claim 1 whereas the removable top has an offset hole in the front center surface of the lid for the motion detector “eye”.
5. A urinal unit as claimed in claim 1 wherein the flush valve is an automatic shut-off type valve.
6. A urinal unit as claimed in claim 5 whereas the flush valve is set to deliver only 15 ounces of fresh water for flushing.
7. A urinal unit as claimed in claim 4 whereas the Motion Detector has two LED lifetime blubs which operate on a battery.
8. A urinal unit as claimed in claim 1 whereas the urinal is fabricated of Polymeric material.
9. A urinal unit as claimed in claim 1 whereas the urinal hangs flush against the wall via two integral hangers on the rear of the unit.
10. A urinal unit as claimed in claim 1 wherein the only liquid maintained in the unit drain system is in the trap while no liquids are maintained in the urinal bowl.
11. A urinal unit as claimed in claim 4 wherein the only electric requirement is found in the Motion Detector battery case which is expected to last a year or more.
12. A urinal unit as claimed in claim 1 whereby the urinal trap is located well below the receptacle bowls vertical drain pipe out of the evaporation air currents, thus limiting evaporation while reducing urine odors.
We also claim
2nd. Independent claim
13. A urinal unit as claimed in claim 1 whereas a hole is wet drilled in the wall of a toilet; just above the base plate, on either side or behind the toilet and a plumbing fitting is inserted using an adhesive, whereby a drain pipe can be connected to the soil pipe via the toilets internal drain pipe.
We also claim
3nd. Independent claim
14. A urinal unit as claimed in claim 1 whereas during manufacturing of the toilet, a threaded hole is made part of the toilet base for the purpose of connecting a drain pipe threaded coupling; after removal of threaded plug, giving access through the toilets internal drain pipe to the soil pipe.
