Combined Toilet and Urinal Device
A toilet accessory has splash guards that may be selectively opened or closed. When opened the splash guards provide lateral and frontal protection. A flush system can be employed to clean the splash guard after use. The assembly can be included as part of a conventional toilet or can be provided in portable, disposable versions.
The present invention relates generally to toilets and, more particularly, to devices that selectively combine the features of a urinal and a conventional toilet.
BACKGROUND OF THE INVENTIONConventional toilets accommodate those who choose to use them in both the sitting and standing positions. In contrast, a conventional urinal is intended for standing use only. Some of the advantages of a conventional urinal reside in the fact that the urinal is shaped to protect along a much more extensive vertical surface than is a conventional toilet.
This protection becomes important in a variety of situations. For example, splashes outside the toilet bowl can be expected when a young child is being toilet trained. Persons who are impaired or disabled may also find it difficult to use a conventional toilet in the standing position without causing undesired splashing. With a conventional toilet, the areas where the splashing can occur are often difficult to clean and sanitize such as the space between the toilet lid and the toilet tank.
The efforts of others to combine the functions of both the urinal and the standard toilet are well represented in the prior art. Some have incorporated splash guards to be used with conventional toilets to provide some of the lateral and frontal protection for which urinals are designed. Others have combined separate toilet and urinal facilities in a single device.

While certain of the above-discussed references illustrate attempts at incorporating urinal or urinal-like functionality into conventional toilet structures or providing additional structures to be used with conventional toilets, it is plain that these references illustrate a number of shortcomings.
Urinal-like functionality is provided by including a splash guard arrangement rather than a permanent structure separate from the conventional toilet bowl. In this manner the invention can be used with conventionally-manufactured toilets without requiring extensive modification.
The splash guard should provide adequate splash protection while minimizing the amount of surface area to be cleaned after each use. One way this is accomplished is to make sure that the splash guard opening communicating with the toilet bowl is relatively large.
Such splash guards should also be provided in forms which can be used with toilets temporarily and then removed and discarded. For example, single-use splash guards can be taken on trips and used in public bathrooms, then discarded. Such guards can also be used temporarily when users are ill or when ill for impaired visitors. Removable guards can also be taken off for cleaning and returned to service.
Such splash guards should also incorporate flushing systems that will cleanse the urinal-like structure without requiring costly or complex flushing systems separate from the system already present in the toilet.
Such splash guard flushing systems should be adaptable for use with both the permanent and temporary versions.
I have determined that these objectives can be met by providing a splash guard that can be either incorporated as part of a conventional toilet or can be provided in a form which can be added to an existing toilet as a permanent or temporary expedient.
The present invention includes a splash guard assembly placed on or attached to a conventional toilet between the toilet seat and lid and includes a pair of fan-folded side splash panels joined to a cover which, when raised, extends the panels and forms a back splash panel and which, when lowered, neatly collapses the panels. A splash guard base is also provided to which the lowermost edges of the splash guard panels are attached so that the entire splash guard assembly can be pivoted up and away from the toilet seat allowing the toilet seat to be used in a conventional manner. A down panel extends from the bottom of the back panel to add further splash protection for the toilet.
A flushing mechanism may also be incorporated into the splash guard, preferably receiving its supply of flushing liquid from the toilet flush valve mechanism wherein a portion of the flow from the flush valve mechanism to the toilet bowl is diverted to a series of flush nozzles positioned and angled to clean the surfaces of the splash guard panels and the back panel when the toilet is flushed.
As described herein, certain aspects of the present invention make it adaptable for use with structures that lack some of the elements of conventional flush toilets. For example, certain embodiments of the present invention can be used with chemical toilets, such as those used on airplanes, trains or in stand-alone booths where a seat cover is desirable but where there is no flush system with which to connect. Another example would be a pit-type toilet which may or may not have a seat but which has no associated plumbing. Another example is a stand-alone seat for which a user must provide a receptacle or collector.
It is, therefore, an object of the present invention to provide a urinal-type splash guard to be incorporated into an existing conventional toilet or which may be used as an added feature to an existing toilet.
It is a further object of the present invention to provide such splash guards in forms which are portable for one-time or temporary use.
It is yet another object of the present invention to provide the portable forms of the splash guard as manufactured from materials which are inexpensive and which may be disposed of after use.
It is yet another object of the present invention to provide such splash guard assemblies with a flush system in order to clean the surface of the urinal-type components each time the toilet is flushed.
It is yet another object of the present invention to provide such flush systems in forms which are easily added to or removed from the flush mechanism already installed in a conventional toilet without extensive modification.
These and further objects of the present invention will become more apparent upon consideration of the accompanying drawings which illustrate various aspects of the present invention in a manner which may or may not reflect actual proportions or dimensions.
While the following describes a preferred embodiment or embodiments of the present invention, it is to be understood that this description is made by way of example only and is not intended to limit the scope of the present invention. It is expected that alterations and further modifications, as well as other and further applications of the principles of the present invention will occur to others skilled in the art to which the invention relates and, while differing from the foregoing, remain within the spirit and scope of the invention as herein described and claimed. Where means-plus-function clauses are used in the claims such language is intended to cover the structures described herein as performing the recited functions and not only structural equivalents but equivalent structures as well. For the purposes of the present disclosure, two structures that perform the same function within an environment described above may be equivalent structures.

Thus, in its raised upmost position, splash guard 16 forms a urinal-like configuration with left side panel 22, rear panel 20, right side panel 24 and drop panel 50 acting as shields to any splashing of urine and with the large central opening in splash guard base 14 providing a large open area for liquid flow.
Referring now to
As seen in
Left flush line 58 may be a flexible thermoplastic tube or may even be formed as a channel within splash guard base 14. Left flush line 58 is attached to a water supply segment 62 which extends into flush tank 64 of the toilet to which seat 10 is attached. Tank 64 has a flush regulator 66 which, typically, allows tank 64 to refill after a flush and also allows a flow of flush water to stand pipe 68 to refill the bowl of the toilet while flush regulator 66 is simultaneously allowing tank 64 to be refilled. In the embodiment shown in
Thus, flush water will travel from Y connector 70 through left flush line segment 62 and left flush line 58 to left flush nozzle 54 during the time that flush regulator 66 is allowing water to refill tank 64. When the supply of flush water has reached a pre-selected level, flush regulator 66 will interrupt the flow of incoming water and thereby cease the flow of water through left flush nozzle 54.
In an alternative embodiment, as seen in
Referring now to
It should be understood from the foregoing descriptions and explanations that right flush nozzle 56 and right flush line 60 are similarly secured to flush base 14 in accordance with the embodiments described above. Preferably, right flush line 60 also attaches to flush line supply segment 62 such that the flow of water through left and right flush nozzles 54, 56 is substantially equal.
Preferably, left and right flush nozzles 54, 56 are angled and positioned such that a flow of flushing water will contact left and right side panels 22, 24, back panel 20 as well as drop panel 50. While two flush nozzles have been shown and described in the foregoing illustrations, it should be understood that additional flush nozzles can be added and positioned to achieve a desired flush flow pattern. Because of the large central opening in flush guard base 14 only the side and back panels must be flushed.
