DETAILED DESCRIPTION OF THE INVENTION

(18) Referring to the accompany drawings wherein the same reference numbers refer to the same or similar elements, FIG. 1 shows a combination toilet and sink assembly in accordance with the invention, also referred to as a combined toilet and sink unit, and is designated generally as 10. By providing the toilet and sink as a common unit, it is meant that they share a common base, i.e., the base of the toilet or what is commonly known as the toilet bowl, and the sink does not have a conventional support structure such as a vanity or legs. Rather, the sink is supported by and on the toilet base and the water connections for the sink are at least partly integrated into the toilet base. Thus, when installing the toilet and sink unit, the installer has only to handle a single unit, place the single unit on the structure built to accommodate the toilet (which may be a conventional drain and securing bolts) and then make flow connections for the toilet and additional flow connections for the sink, namely, only an intake water supply for the sink. The outlet from the sink is the same as the outlet from the toilet and therefore a separate outlet connection from the unit for the sink is not necessary.

(19) The assembly 10 includes a toilet portion 12 which is used in the conventional manner in which a toilet is used. Components of the toilet portion 12 that are not essential to the invention are not shown, it being understood that such components are present in some form to enable use of the toilet in the conventional manner. Such components include a seat, and one or more of bearings, bushings, fasteners, washers, seals, an actuating/flushing mechanism, conduits and their connections, floats and valves. Also, it should be understood that the toilet portion 12 is connected to an external source of water to provide water to enable use of the toilet. The toilet portion 12 thus includes the features disclosed below that are needed to enable a person to urinate or defecate into the toilet bowl (or waste receptacle) and enable removal or flushing of the waste in the bowl, and repeating of this process.

(20) In a similar manner, the assembly 10 includes a sink portion 14 which is used in the conventional manner in which a sink or wash basin is used. Components of the sink portion 14 that are not essential to the invention are not shown, it being understood that such components are present in some form to enable use of the sink in the conventional manner. Such components include one or more of bearings, bushings, fasteners, washers, seals, and conduits and their connections. Also, it should be understood that the sink portion 14 is connected to a source of water, typically an external source of water, to provide clean water to enable use of the sink, and this external source of water may be the same as or different from the external source of water being used to provide water for the toilet portion 12. The sink portion 14 thus includes the features disclosed below that are needed to enable a person to activate a stream of water to, for example, wash their hands, and drainage of this water, and repeating of this process.

(21) The assembly 10 includes a toilet base 16 having a front and rear, and which is formed in any form as a toilet, the illustrated form being for purposes of explaining the invention but is not meant to limit the invention in any manner whatsoever. As with a typical toilet base, the base 16 includes a toilet bowl portion or waste receptacle 18 having an outlet 20 in a bottom region and a channel 22 rearward of and leading into the waste receptacle 18 to enable a flow of water to be used for the flushing to enter into the waste receptacle 18 (see FIG. 10).

(22) A reservoir tank 24 is coupled to a rear portion of the base 16, usually placed onto a rear projecting portion of the base 16 and secured thereto by appropriate securing hardware (not shown). The reservoir tank 24 includes an interior water receptacle 26, a water inlet (not shown) to the water receptacle 26 which is adapted to be coupled to an external source of water (not shown) and a water outlet 28 from the water receptacle 26 at a vertical height above at least part of the waste receptacle 18 (and the flushing hardware (not shown)). The water outlet 28 is preferably in or at a bottom region of the reservoir tank 24. Reservoir tank 24 should be considered an optional feature since there are toilets that do not include such a stabilizer-type tank and instead receive water from a wall-mounted system or are tankless. These alternative toilet portions are within the scope and spirit of the invention.

(23) The reservoir tank 24 has a removable lid 30 to enable access to the interior water receptacle 26 in which typical flushing hardware (not shown) is situated. The reservoir tank 24 and lid 30 are shown in a generally circular cross-section shape but the shape of these elements in the illustrated embodiment is not intended to limit the scope of the invention, and other shapes are contemplated and within the scope of the invention.

(24) The base 16 includes a first conduit 32 extending from a water inlet 8 of the base 16 aligning with the water outlet 28 of the reservoir tank 24 to the waste receptacle 18, preferably to an upper region thereof, to enable inflow of water from the water receptacle 26 through the water outlet 28 thereof and through the water inlet 8 of the base 16 into the waste receptacle 18. This water inflow is operatively controlled, i.e., upon flushing of the toilet by for example depressing a toilet lever or triggering of a sensor, and operates by the effect of gravity (as in conventional toilets). The first conduit 32 is preferably formed in an upper region of the base 16 and extends from a rearward location at which water first enters the first conduit 32 from the water receptacle 26 in the reservoir tank 24 and includes an annular portion around the upper region of the waste receptacle 18 to potentially reach the front end region of the base 16 (see, e.g., FIG. 8).

(25) After flushing of the toilet, the waste water in the waste receptacle 18 flows out of the waste receptacle 18 and out of the toilet base 16 through a second conduit 34 in the toilet base 16 extending from the outlet 20 of the waste receptacle 18 to an opening 36 in a lower surface of the toilet base 16 at a vertical height below the outlet 20 of the waste receptacle 18, and which is at the rear of the base 16. This vertical difference in height enables outflow of waste water from the waste receptacle 18 to an exterior of the base 16, as in conventional toilets. The location of the outlet 20 of the waste receptacle 18, the location of the opening 36 in the base 16 and the shape of the second conduit 34 therebetween can vary, as is known to those skilled in the art to which this invention pertains.

(26) The sink portion 14 of the assembly 10 includes a sink 38 having a drain 40 in a lower region thereof, and a conduit member 42 connected at one end region to the drain 40 of the sink 38. The conduit member 42 extends from the drain 40 of the sink 38 to the channel 22 of the base 16. The conduit member 42 defines part of a third conduit from the drain 40 to the waste receptacle 18 since it is desirable to use the water draining from the sink 38 for the toilet or at least to avoid the need for an additional drain out from the base 16. The sink drain 40 is what is referred to as a trapless sink drain and discharges directly into the toilet bowl or waste receptacle 18 via the channel 22. The channel 22 includes a small chamber with rolled edge to prevent splashing of the water being discharged through the outlet of the conduit member 42 (see FIG. 9).

(27) Importantly, the conduit member 42 is pivotable about a vertical axis VA such that as the conduit member 42 pivots, the sink 38 connected thereto also pivots (see FIG. 10). More specifically, the conduit member 42 is configured to be pivotable between a first position in which the sink 38 is in a position directly (vertically) above at least part of the waste receptacle 18 (see FIGS. 1, 2, 4, 11 and 14) and a second position in which the sink 38 is in a position completely not (vertically) above the waste receptacle 18 (see FIGS. 5, 12 and 13) to enable use of the waste receptacle 18, i.e., the toilet. The vertical axis VA is preferably perpendicular to the horizontal plane, i.e., the plane onto which the assembly 10 is installed. However, the invention is equally usable if this vertical axis VA is not exactly perpendicular to the horizontal plane and a slight variation from the vertical is possible. The extent of this slight deviation from the vertical would be determined through construction of the assembly 10. An exact vertical axis VA would obviously prevent outflow from the sink 38 of any residual water in the sink 38 after use, but the same effect could be achieved with a slight variation from the vertical and by suitable design of the sink 38. As such, the substantially vertical axis should be considered to 90 degrees to the horizontal plane plus or minus about 10 degrees, i.e., 80 to 100 degrees from the horizontal plane.

(28) In a preferred embodiment, the second position is about 90 degrees about the vertical axis VA from the first position, and in fact, a little more than 90 degrees as shown in FIG. 5. This allows the person unblocked use of the toilet portion of the assembly 10 since the sink 38 is entirely to the side and not over any portion of the waste receptacle 18. Compare also FIGS. 13 and 16 showing the position in which the sink is swung away from a position directly above the waste receptacle 18 to enable use of the waste receptacle 18 (toilet) to FIGS. 14 and 15 in which the sink 38 is directly over the waste receptacle 18 and does not allow for use thereof.

(29) The base 16 includes features to enable the sink portion 14 to function. Specifically, the base 16 includes a projection 44 extending upward from the upper surface of the base 16 alongside the waste receptacle 18. As shown, the projection 44 is rearward of the waste receptacle 18 and forward of the reservoir tank 24, i.e., between these two elements, and in a central region of the base 16. The projection 44 may be alongside and in contact with the front surface of the reservoir tank 24, as seen in FIG. 10. The projection 44 includes an elongate, vertically oriented channel 46.

(30) The conduit member 42 includes a vertical portion 48 rotatable in the channel 46 and a horizontal portion 50 above the vertical portion 48, thereby forming an elbow 52. Channel 22 in the base 16 is under the channel 46 in the projection 44 and in flow communication therewith and thus also in flow communication with the vertical portion 48 of the conduit member 42 in the channel 46 (see FIG. 10). The horizontal portion 50 is partly under the sink 38. A casing 54 encloses a portion of the horizontal portion 50 of the conduit member 42 between the drain 40 and the reservoir tank 24. The casing 54 is shown as a two-part casing 56, 58 with each part including a channel adapted to the shape of the horizontal portion 50 of the conduit member 42 (see FIG. 3).

(31) The sink portion 14 also includes a pivotable faucet 60 having a spout or conduit member 62 defining a water channel with a water inlet 64 and a water outlet 66 that is at a vertical height above the sink 38. The faucet 60 may be coupled to the conduit member 42 such that it also pivots upon pivotal movement of the conduit member 42. As such, when a person takes hold of the sink 38 to pivot it about the vertical axis VA, the person is able to cause pivotal movement of the sink 38, the conduit member 42 and the faucet 60. In a similar manner, by taking hold of the faucet 60 and pivoting it about the vertical axis VA, the person is able to cause pivotal movement of the sink 38, the conduit member 42 and the faucet 60 as a unit. By aligning the pivot points of the sink drain 40 and faucet 60, both parts can remain aligned in any position. The reservoir tank 24 acts as a stabilizer and clamp.

(32) In one embodiment, the faucet 60 may be coupled to the casing 54 to provide for linked pivotal movement of the conduit member 42, the casing 54 and the faucet 60. In such an embodiment, the sink 38, the conduit member 42 inside the casing 54 and the faucet 60 all pivot about the same vertical axis VA. Such linked pivotal movement though is not required in all embodiments of the invention. In this case, it is possible that the sink 38 and conduit member 42 inside the casing 54 could pivot about a different axis than the faucet 60, e.g., a different vertical axis.

(33) An alignment member, such as an alignment pin 68, may be provided and arranged partly in an aperture in the casing 54 and partly in an aperture in the reservoir tank 24 above the casing 54, see FIG. 10, to facilitate the pivotal movement of the casing 54 and thus the conduit member 42 partly enclosed thereby and the sink 38. Also, the alignment pin 68 aids in supporting the swing arm cantilever provided by the conduit member 42 and casing 54.

(34) To provide water for the faucet 60, the assembly 10 includes a fourth conduit 70 partly in the projection 44 in the base 16 and partly in the reservoir tank 24 (see FIG. 10). Fourth conduit 70 has a water inlet 72 at the bottom of the part 70A in the base 16 adapted to be coupled to an external source of water in a conventional manner, and a water outlet 74 at the top of the part 70B in the reservoir tank 24 communicating with the water inlet 64 of the faucet 60. The faucet 60 includes a handle 76 or other flow control device to enable the inflow of water from the water outlet 74 of the fourth conduit 70 to the faucet 60, and thus through the faucet 60 to the water outlet 66 thereof, to be controlled as desired.

(35) As shown in FIG. 3, and as also can be seen from FIG. 10, the part 70A of the fourth conduit 70 that is in the projection 44 in the base 16 is behind the channel 46 in the projection 44, i.e., in line therewith but closer to the water receptacle 26 in the reservoir tank 24. In this manner, it is possible for the sink 38 and connected structure, i.e., the conduit member 42, the casing 54 and the faucet 60, to pivot in both directions about the vertical axis VA, i.e., to the left and to the right of the waste receptacle 18. This is very useful since the assembly 10 could be assembled and allow for both leftward pivotal movement of the sink 38 and associated structure and also rightward movement of the sink 38 and associated structure. There is no need to construct separate assemblies with a left pivoting sink and another one with a right pivoting sink. Rather, a single assembly addresses both installation.

(36) Although it is possible to position the part of the fourth conduit 70 that is in the projection 44 in the base 16 and the channel 46 in the projection 44 in a side-by-side arrangement, this would substantially limit the design to allow for pivotal movement of the sink 38 and associated structure in essentially only one direction from the position above the waste receptacle 18, i.e., toward the side away from the part of the fourth conduit 70. As such, it would be necessary to construct an assembly with a left-handed swinging sink 38 and another assembly with a right-handed swinging sink 38, the relative position of the part of the fourth conduit 70 that is in the projection 44 in the base 16 and the channel 46 in the projection 44 being switched between these embodiments. Nevertheless, such right-hand only or left-hand only sink swinging embodiments are within the scope of the invention. As such, the projection 44 is constructed to provide the position of the part of the fourth conduit 70 and the channel 46 preferably as shown, but this positioning is not intended to limit the invention.

(37) To provide a support for the faucet 60, the reservoir tank 24 includes a protrusion 78 on a front side, i.e., the side facing the waste receptacle 18. This protrusion 78 has an upper portion 80 projecting more forward than a lower portion 82. A portion of the fourth conduit 70 passes through the protrusion 78 (see FIG. 10). The upper portion 80 of the protrusion 78 supports the faucet 60 and has an opening through which water operatively flows from the fourth conduit 70 into the faucet 60. Sealing structure for this flow connection is present, but not shown. The aperture into which the alignment pin 68 is received is formed on a lower surface of the upper portion 80 of the protrusion 78. The lower portion 82 of the protrusion 78 is adjacent a rear end region of the casing 54.

(38) An elongate movement synchronizing bar 84 is also optionally provided, connected at one end to the faucet 60, e.g., the spout 62 thereof, and rests on the casing 54. The bar 84 prevents user error and hassle since it enables synchronized or linked movement of the sink 38 and faucet 60 (in the embodiment wherein the sink 38 and faucet 60 rotate about the same vertical axis VA), but has no bearing on functionality otherwise since such synchronized or linked pivotal movement is not required. In an embodiment wherein the synchronizing bar 84 is not provided, the user would have to independently swing the sink 38 and the conduit member 42 and casing 54 unit, and then also swing the faucet 60, which could swing about the same vertical axis VA or different axes, and not even different vertical axes since one or more of the axes could be other than vertical.

(39) Although the assembly 10 is described above as a combination of a toilet portion 12 and a sink portion 14, each of these portions could be used independently, e.g., the toilet portion 12 could be used with a different sink portion and the sink portion could be used with a different toilet portion, provided the other portion has the necessary fluid connections. Thus, the toilet portion and the sink portion should also be considered separate and independent inventions. Preferably though, they are used together connected in the manner disclosed above.

(40) Another variant of the invention is an assembly wherein the reservoir tank 24 is not a stabilizer tank per se. Rather, the water receptacle to enable flushing of the toilet is provided by a wall-mounted reservoir or a tankless commercial toilet setup. In such embodiments, both the swing arm (the conduit member 42 and its casing 54), and the faucet 60 will be supported only by the upright projection 44 of the base 16, without a reservoir tank behind the projection 44.

(41) Another embodiment of the invention includes a wall-mounted bowl, instead of mounting the toilet portion 12 onto a horizontal surface. In this case, the toilet base 16 may be configured to provide for a waste outlet into a vertical wall instead of a horizontal floor, i.e., from a rear surface on a side of the toilet base 16. In such an embodiment, the second conduit 34 in the toilet base 16 would extends from the outlet 20 of the waste receptacle 18 to an opening in the rear surface of the toilet base 16 at a vertical height below the outlet 20 of the waste receptacle 18. Suitable mounting connections are provided in the vertical wall, and in the rear, wall-facing surfaces of the toilet base 16.

(42) Dimensions for the components of the assembly 10 are not provided herein. Such dimensions are determined by building code clearances. In one embodiment, the assembly 10 can be constructed so that, when applied to residential spaces, the assembly 10 yields a minimum usable area that is about 40% smaller than the area of a typical sink-toilet setup. As such, even the tapered shapes are intentional to allow for use of a standard sized sink and toilet.

(43) Many changes, modifications, variations and other uses and applications of the subject invention will, however, become apparent to those skilled in the art after considering this specification and the accompanying drawings which disclose the preferred embodiments thereof. All such changes, modifications, variations and other uses and applications which do not depart from the spirit and scope of the invention are deemed to be covered by the invention which is limited only by the following claims. Among other modifications, features of the U.S. and foreign patent documents mentioned above, all of which are incorporated by reference herein, can be used in the combination toilet and sink assembly in accordance with the invention to the extent possible, and all such modifications are considered by the inventor to be part of the invention.

(44) The foregoing detailed description provides an explanation of various aspects of the disclosed technique for combining toilet functions and sink functions in a common unit or assembly. The purpose of this explanation is to provide a thorough understanding of the different aspects of the disclosed assembly.
