WATER CLOSET Filed March 7, 1956 I 5 Sheets-Sheet 5 IN V EN TOR.

United States PatentC The present invention relates to a toiletor water closet;

While many featuresof the" present residential toilet have been improved: and modernized, the apparatusis still distinguishable by its customary design and mode of operation. For instance, even .the most modern vwater closet; of the type presently in use utilizesa flush tank which. is positioned to the rear of the bowl and conven: tional flush mechanism operated by-a handlegfor releasingwthe. water in the flush tank for-flushing the bowl. Therbowl is in almost every instance in; the form of a, pedestal which encloses and, incorporates a water trap. While much eifortand energy. has been directed. toward modernizing and improvingother appliances, found in thehome, such asfor example, kitchen appliances, not onlytto improve, their operation and utility but to make these devices more pleasing in appearance, nothing has been accomplished" toward improving the operation or utility of a watercloset nor toward making a water closet more pleasing in design. The commercial water closet oi: the. type generally in usediffers from the residential water closer only in that, it does not have a fiushbox andassociated flush mechanism but instead incorporates ar -suitable metering valve which is manually activated. A closet of this typehowever is dependent upon a one inch water inlet which=in most instances is larger than the inlet used for residential buildings.

The 1 present invention. contemplates a water closet which is'a great departure in design and operation'frorn the conventional type presently in use. The water closet of the'present invention eliminates, the flush tank and the manually operated mechanism for elfecting operation of the water closet. Thewater closet of thepresent invention further is completely enclosed when not in use, and thebowl' is swingable from an upwardly inclined position, to'a horizontal operative positionand the flushing mechanism of the closet is automatically responsive to the position of the bowl. When the closetof the present invention is in its. closed non-use position, the overall area of the closet is roughly /3 to /2 that of the conventional water closet, or in. other words, the. closet of the present invention when in its non-use position will takeup roughly /3 to 1/2 the space requiredfor the conventional closet. Also, when the closet is in its non-use position, it has the appearance of a cabinet so, that the bathroom can be made tolook as inviting and pleasing as any other room of the house. Th'e closet of the present invention further incorporates a .fHis and Her position, and in each instance the mechanism is automatically self-flushing when the closet is returned to its non-use position; The bowl itself incorporates self-cleaning mechanism which is also automatically operative in a predetermined cycle. It will be appreciated, therefore, that the closet of the present invention is a radical departure from the water closet of the type presently in use in that among other things the flush tank and associated flush mechanism is eliminated, the bowl is self-cleaning, the bowl is swingable from its enclosed upwardlyextending discharge position to its horizontal use position, the bowl incorporates Her features and His features which are independent of .each other, the. apparatus ,is automatically self-flushing and the bowl is automaticallyselfcleaned, the bowl isdry when in its non-,useposition, and the closet when in its non-use position is completely ice enclosed in a cabinet which comprises roughly /3 19.- 151' the space. of the conventional water closet.

It is a principal object of the present invention there-1 fore, to improve the operation and construction of-dee. vices; of this type.

A- further object of the present invention is to PIG!) vide a water closet which is completely enclosed when in its non-use discharge position.

Another object of the present inventionis to provide a -water closet having His or Her characteristics..-

Aastill, further object of the present invention is to provide a toilet bowl having an enclosed spray system,

which is automatically operative for spraying the bowl- A still further object of the present invention is to provide a toilet-bowl having an automatic spray system in combination with a detergent system for automatically sanitizing the bowl when in non-use.

Yet another object of the present invention is to. provide means for automatically filling the trap upon com: pletion of the flushing operation and for automatically directing a predetermined amount of water into the bowl while at the. same time wetting the sides of the bowl just prior to use.

A still further object of the present invention is to provide a water closet which is pleasing in design, which is, simple in operation, which can be easily manufactured and which can be easily installed either as a replacement item or as original equipment.

To the'accornplishment .of the foregoing and related ends, said invention then comprises the features herein: after fully described and particularly pointed out in the claims, the following description and the annexed drawing s setting forth in detail certain illustrative embodi: ments ofthe invention, these being indicative, however, of but a 'few of the various ways in which the principles of the, invention may be employed.

Fig. 10 is a diagrammatic plan view of the wiring cit? cuit for interconnecting the closet of the present invention with a source of electrical energy.

Referring to Figs. ,1 through 6 of the drawings thewater closet of the present invention when in i ts.non-use :posi.- tion is in the form of a cabinet generally .designatedby the number 10 and which. preferably extendsfrom a room wall 11, cabinet 10 having side walls 12, a front wall 13,.and a top wall 14, each of the sidewalls 12 and;front wall 13 having a flange 14a for sealing the .cabinetto the view similar to Fig. 3 showing the Herf floora In a typicalinstance, cabinet lo measures 24-inches in width, 27 inches in height and 14% inches in depth,

assuming-that the plumbing outlet or bell is at a '4 inch center from the wall 11. If the plumbing outlet or hell is at a 12 or 14 inch center from the wall 11, the depth of the cabinet will measure 16% inches or 18% respectively. It will be appreciated, therefore, that closet 10 is very compact and decorative when in its non-use position and does not have the appearance of the conventional water closet.

The functional mechanism of closet 10 comprises a base 15 which is preferably formed of cast iron porcelainized and which is in the form or nature of a trap or siphon. The base 15 is suitably fixed to the floor 16 by bolts or screws 17 or any other suitable means so as to enclose the inlet of a plumbing outlet or bell 18. To suitably seal the base or trap 15 with the plumbing outlet or bell 18, a sealing ring 19 of any suitable construction can be employed which encloses a sealing gasket 20 in a manner well known in the art.

The base 15 acts as a pedestal for swingably supporting a bowl 21, and a pair of standards 22, see also Fig; 7, extend from opposite sides of base 15 adjacent the inlet thereof to which are suitably fixed a pair of brackets 23.

Each of these brackets 23 has an upwardly open saddle I '2,879,519 j T 7 Cabinet 10, as previously suggested, consists of two side walls 12, preferably formed of any suitable rigid material such as stainless steel, which are suitably secured adjacent their lower ends to opposite sides of the pedestal and are tied together adjacent their upper end by a rigid cross member 31. The side walls are also preferably sealed to the floor, as previously suggested, to facilitate cleaning around the closet. The front wall 13 consists of three panels, a bottom panel 32, a middle panel 33 and a top portion 24, and the bowl 21 has a seat 25, as will be more fully explained hereinafter, which has a pair of downwardly depending spaced arms a on the opposite sides thereof which carry adjacent their lower ends a suitable pin 26. The pin 26 of each pair of depending arms 25a is received in the saddle portion 24 of its supporting bracket 23 so that the bowl is carried by the brackets for up-and-down swinging movement. It will be appreciated, therefore, that the bowl is swingably supported by the base or trap 15 to move from an upwardly inclined discharge position relative to the inlet of base 15 to a substantially horizontal use position, and, as will be more fully appreciated hereinafter, the bowl can be easily removed from the pedestal by merely slipping out the pins 26 from their location in the saddle portions 24 of the brackets 23.

The bowl can be formed of any suitable material such as, for instance, vitreous china, enamelware, plastic or stainless steel, and a discharge opening 27, in the form of a pipe section 28, is provided in the rear of the bowl in discharge alignment with the inlet of the trap when the bowl is moved into its upwardly inclined non-use position. The seat 25 which is preferably contoured in configuration and formed of plastic is suitably fixed to the upper rim of the bowl so as to constitute an integral part therewith, and this seat has incorporated in its rearward portion a suitable water reservoir 28a which leads into a duct 29 which extends around the inner edge of the bowl and a plurality of distributing openings or slits 30 connecting the duct 29 with the inside of the bowl so that liquid in the reservoir can be directed through the cross-section and its interconnection with duct 29 so located that when the bowl 21 is in its upstanding nonuse position, and assuming that thereservoir is full of water, substantially the upper half or level of the water in the reservoir 28a will empty by gravity into duct 29 and through distributing openings30 into the bowl'21 wherein it willflow through discharge opening 27 into trap 15. And aswill be more fully appreciated hereinafter, the reservoir is so shaped that the amount of water flowing into trap 15 when the bowl is in its non-use position is sufiicient to fill the trap upon completion of the flushing operation. When the bowl 21 is in its substantially horizontal or use position, the remaining water in the reservoir 28a will flow by gravity through duct 29 and openings 30 into the bowl 21 so as to fill the bowl 'with a predetermined amount of water while at the same time wetting the sides of the bowl immediately prior to use. I

panel 34. The bottom panel 32 is suitably fixed to the pedestal 15 and to the side edges of each of the side walls 12 and preferably sealed to the floor as previously suggested. The middle panel 33 has a pair of pins 35, see Fig. 8, only one of which is shown, extending from the opposite sides thereof which are received in suitable bearings 36 fixed with the side walls 12 so as to be carried thereby for up-and-down swinging movement. Each of the pins 35 receives a coiled spring 37 which is fixed at its one end to its associated pin 35 and at its other end to its associated bearing 36 so that the middle panel is resiliently urged to move into a normal upstanding position. The top panel 34 is an extension of the front edge of the seat 25 in the form of a skirt or front face 38 which is fixed to the outer surface of the bowl 21. The skirt 38 also has side walls 39 which extend from the side edges of the front face 38 to the bowl 21 and to the seat 25 so that when the bowl 21 is in its horizontal or use position that portion of the bowl 21 which extends outwardly beyond the front edges of the sides wall 12 is completely enclosed by the skirt 38 and its side walls 39. When the closet is in its non-use closed position, the lower edge 40 of the skirt 38 overlaps the upper edge 41 of the middle panel 33 so that when the bowl 21 is moved into its use position, the middle panel 33 is urged to swing against the force exerted by the coil springs 37 outwardly and downwardly a distance sufficient to permit the lower edge 40 of the top panel to move into abutment with a stop 42 formed as a part of the base or pedestal 15. It

' 1 will be appreciated, therefore, that the top panel 34 defines the horizontal use position of the bowl and in so doing urgs the middle panel 33 to swing into its out-of-the-way position by reason of its overlapping relationship with respect to skirt 38. The top wall 14 of the cabinet is in the form of a lid 42a which carries a pair of pins 43 which extend from its opposite sides, only one of which is shown. Each of pins 43 is rotatably received by a hearing 44 formed in the cross member 31 adjacent the opposite side walls 12 so that the lid 42a is swingably sup ported for up-and-down swinging movement. As will be more fully appreciated and explained hereinafter, the lid 42a is preferably formed of plastic and is of hollow construction and serves as a reservoir for a detergent solution. The inner wall 45 of the lid 42a is suitably contoured so that when the lid is in its raised position it will provide a comfortable back rest in combination with the contoured seat 25. The lid is link connected with the seat 25 of bowl 21 by a suitable rigid member 45a, and the bowl and the lid are suitably counterbalanced by a spring 45b so that the bowl will be urged to move into its horizontal use position upon the lid being swung upwardly into its back rest position. When the lid 42a is swung downwardly into its closed position, the bowl 21 will be urged to move into its upstanding non-use posiits normal upstanding position upon face 38 of the top panel 34 being moved into its vertically disposed position. To retain the lid 42a in its closed position a magnetic latch 46 is provided which consists of a magnetic element 47 carried by the lid and a magnetically responsive ele' ment 48 carried by one of the side walls 12. It will also be appreciated, that when the bowl is in its horizontal use position, the top edge 49 of each of the side walls is at a height which provides convenient arm supports.

As previously suggested, the water closet of the present invention incorporates His characteristics as well as Her characteristics. More specifically; the fieend of the bowl is' in the form of a urinal lid or trough 50 which is swingably' connected by suitable pins"51; This lid has a front face 52 which when in it's'closed position is substantially co-planar with the face 38'of the top panel 34 of the front wall 13 so that when the lid is closed, and when the closet is in its non-use closed position, the urinal lid does not present an obstructiodto otherwise break up the front wall panel design except for a'suitable handle 53. The lid 50 also has a pair of side walls 54 so that the lid is in the form of a trough when moved into its open position. The under surface of the forward end of the seat 25 has formed therewith or affixed theretoa liner 55, preferably formed of stainless steel or plastic, which has a downwardly and backwardly curved deflector 56 extending therefrom, and suitable distributing openings 57 are formed in the deflector 56 in align inent with the distributed openings 30 interconnected with the adjacent port 29 so that upon actuation of the spray; ing system, as willbe fully explained hereinafter, the lid 50 will be washed and cleaned. For retaining thelid in it's closed position, a suitable magnetic latch 58 is provided which includes a magnetic element 59 carried by, the seat and a magnetically responsive elem-enter) carried by the lid.

v Referring to Fig. 9, the water supply is directed into the closet by means of an inlet pipe 61. The inlet pipe is connected to a suitable manually operative valve 62 which in turn is connected by a union 63 to one end of a" solenoid operated normally closed valve 64-. The oith'erend of the normally closed solenoid operated'valve 64" isconnected to the inlet of a right-angle anti-bacli siphon 65by means of suitable piping 66, the anti-back siphon 65 being located well above the bowl 21 and its seat 25 when the bowl is in its horizontal use position. The outlet end of the right-angle anti-back siphon 65- is connected to the inlet end of a straight-through anti-back siphon 67 by means of suitable piping 68, this straightthrou'gh anti-back siphon 67 being locatedbelow the rightangle anti-back siphon 65. It will be noted that piping 68"prior to its entry into the straight-through anti-back siphon 67 incorporates a T-section 69 so that only approximately /3 of the volume of water being directed through the piping 68 goes through the straight-through anti-back siphon 67 while approximately the other /a' of the volume of water is directed downwardlyinto thebottom of the trap 15 so as to act as a jet during flushing operations This water is carried inpiping 70 which is fixed in the trap by means of a suitabl'e lockmeans 71. The outlet end of the straight-through anti-back siphon 67' is connected-by a flexible piping 72 with the reservoir 28a in the seat so that water will be directed through the duct 29 and openings 30 against the inner surface of -the bowl 21 simultaneously with the trap flushing operation. It will be appreciated that the volume of water during the operation of the spray cycle directed into reservoir 28a is greater than the volume of water being directed out of the reservoir into duct 29 and through openings 30 so that the reservoir is filled during the spraying opera-tidn and the water is directed into duct 29 and through openings 30 under pressure.

Each of the side walls 12 has an inside panel'72a' and a portion of piping 66, anti-back siphon 65, piping 68, anti-back siphon 67, and a portion of piping 70 and flexible piping 72 is located adjacent the inner face of one of the side walls and enclosed by its associated p'a'nel 72a so as not tobe visible when the closet is moved into its Her position.

As previously suggested, the lid 42a is in the formof a reservoir for carrying a detergent solution. More specifically, a metering tube 73 is positioned in the reservoir with its open end 74 adjacent thelowest point. The outlet end, of the tube 73 is connected with one of the pivot pins 43 which is tubular and which in turn, is connested adjacent its other end by means of a suitable pipe 7'4 to the top of the" anti-back siphon 67 :0 that when the top lid 42a is swung into its raised'backrest position, the tube 73 will be filled with a predetermined amount of detergent solution which in turn will be directed into piping 74a and consequently into the anti-back siphon 67. The level of the detergent solution in' thetop lid is maintained below the inlet 74 of the metering tube 73 when the lid is in its raised position so that only a pre-' determined amount of 'this solution can be directed into the anti-back siphon 67.

As prew'ously suggested, the spraying and flushing operations are automatically responsive to the position of the bowl 21 or to the position of the urinal lid 50. More specifically, a microswitch 75 is associated with the urinal lid 50 so as to be in'its open position upon the urinal lid being in its closed position, and a microswitch 76 is located on the stop 42 and is in its open position when the bowl 21 is in its non-use upstanding position; The microswitch 76 is connected to a source of electrical energy 77 in series with a timing relay78 and a solenoid 79 of valve 64, and the timing relay is such that on being actuated or regenerated it will energize the solenoid for a predetermined length of time, say for instance, 30 seconds; The switch 75 is connected to switch 76 in series so that switch 75 is a slave to master switch 76.

v In the operation of this device and assuming the closet to be in its closed position, the urinal lid 50 can'be swung into its open trough-like position upon the operator pulling downwardly upon handle 53. When the lid 50 is moved into its closed position, the switch 75 is moved into its open position and energizes the timer relay 78, switch 76 being in its normally openpo'sition,

which in turn energizes the solenoid 79, and solenoid valve 64 is moved into it's open position. The water is then directed through anti-back siphon 67 into the reservoir 28a of the seat 25 and tends to fill the reservoir which, as previously suggested, is substantially halfful'l when the bowl is in its discharge positiom After the reservoir has become completely full, the water is 'directed under pressure into the distributing duct 29 and through the outlet openings 30 against the inside surface of the bowl 21 and lid 50. Simultaneously, water is being directed downwardly in piping 70 and into the trap in the form of a jet for flushing the trap. After a predetermined length oftime, the timer rela'y 78 cuts off, the solenoid 79 is deenergized and the valve 64 returns to its normally closed position. The reservoir 28a in the seat 25 at this time is completely filled, and. the antiback stop 67 prevents any of the water from flowing backwardlythrough the piping 72. Substantially half of the water in the reservoir, therefore, flows into the bowl 21 and consequently into the trap so as to fill the trap with a predetermined level of Water in the manner as previously suggested 'so that in no instance is the trap *ever left completely dry after the flushing operation.

When the bowl 21 is next moved into its horizontal use position, the remaining water in the reservoir 28a flows into the bowl 'so as to fill the bowl to a predetermined level. With the bowl 21 in its horizontal use position, the microswitch 76 is in its closed position, and in'i- 'mediately upon the bowl being raised from its use position, the microswitch 76 resumes its normally open position and again reactivat'es the timer relay 78 for a pre determined interval. Upon the bowl 21 assuming its discharge position, the contents of the bowl'are'dischar'ge'd into the trap and the trap is flushed and the bowl: is sprayed with a jet of water in the same manner as described with reference to the operation or the urinal lid 50 for 'a predetermined length of time; Upon comple-' tion of the spraying and flushing operation, or in'oth'er words, upon the solenoid 79 being dc-energized, the upper level of the water in'theseat reservoir 28a flows into the bowl and 'eons'eque'ntly into-"the trap so 'as't'o again fillthe trap with a predetermined amount of water. It will be appreciated that when the bowl is in its use position, that movement of the urinal lid from its open to its closed position cannot actuate the flushing and spray cycle inasmuch as the bowl microswitch 76 is in its closed position. It will also be appreciated that when the bowl is moved from its use to its discharge position, a metered amount of detergent solution will be directed into the anti-back siphon 67 which in turn will be mixed with the water being directed into the reservoir 28a so as to sanitize and clean the bowl during the spraying operation.

As previously stated, the middle panel 33 is swingable forwardly and downwardly. It will be appreciated, therefore, that access to the inside of the closet when the closet is in its closed position can be had upon swinging middle panel 33 into its open position.
