## Background
RELATED APPLICATIONS
This application is a continuation in part of International Patent Application Serial No. PCT/IL2006/000700, filed on Jun. 18, 2006, and a continuation in part of PCT application number PCT/IL2005/000653, filed Jun. 19, 2005.


BACKGROUND OF INVENTION
1. Field of Invention
The present invention relates to a toilet device, in particular a toilet device for use in conjunction with a conventional toilet to facilitate use in a natural squatting posture.
2. Discussion of Related Art
The use of the natural (relatively deep) squatting posture during defecation has been proposed as a healthier and more natural method for defecating. U.S. Pat. No. 4,819,277 (Sikirov) discloses a sanitary appliance useful for such squatting, mountable over a conventional (“western”) toilet; and provides evidence of the amelioration of hemorrhoid symptoms upon use of a squatting posture during defecation. Such a squatting posture may also be beneficial against constipation and other ailments.
WO 03/074799 (Sikirov) discloses a squatting toilet similar in concept to that of U.S. Pat. No. 4,819,277, however comprising an improved urinal pan.
It is well known that upon defecation, the urinary bladder also empties. For this reason, in U.S. Pat. No. 4,819,277 and WO 03/074799 the sanitary appliance and squatting toilet, respectively, each comprise a urinal pan to minimize splashing of urine. However, further improvements in such pan are warranted.
SUMMARY OF INVENTION
The present invention relates to a toilet device designed for use in combination with a conventional toilet (i.e. so-called “western style” or sit-down toilet) for facilitating defecation in a natural (relatively deep) squatting posture. The device is designed to be positioned over the conventional toilet, although it may be incorporated as part of the toilet, for example, as disclosed in U.S. Pat. No. 4,819,277, which is incorporated by reference; WO 03/074799 is also incorporated by reference.
It is a particular object of the present invention to provide such a toilet device comprising a urinal pan that is relatively easy to manufacture and use.
Accordingly, the toilet device of the present invention comprising: a platform adapted to support a user and having areas for a user's feet and an opening therethrough designed to be aligned with the toilet bowl; and a urinal pan to serve a user is in a squatting posture, said urinal pan comprising a front wall and side walls, one edge thereof mounted to said platform and adapted to be pivotably adjustable between an operative position and an inoperative position, characterized in that the urinal pan walls are comprised of flexible material attached to a rinse hose. The flexible material may be sheet material, such as cloth or plastic. The rinse hose is preferably attached to the outer edges of the front and side walls of the flexible sheet material, thus forming a frame around the urinal. The rinse hose has nozzles through which rinse water is sprayed unto the walls of the urinal and valves to control the flow of water. Preferably the device also has a cover over the folding urinal. The cover preferably has handles to facilitate lifting and lowering the urinal. The platform may have legs that fold when the platform is raised and extend when the platform is lowered to an operative position. The device of this invention can be mounted pivotally on top of a conventional toilet bowl.



BRIEF DESCRIPTION OF DRAWINGS
The accompanying drawings, are not intended to be drawn to scale. In the drawings, each identical or nearly identical component that is illustrated in various figures is represented by a like numeral. For purposes of clarity, not every component may be labeled in every drawing. In the drawings:
The invention may be more clearly understood upon reading of the following detailed description of non-limiting exemplary embodiments thereof, with reference to the following drawings, in which:
FIG. 1 is a perspective view of a further embodiment of the toilet device of the present invention comprising another modification of the urinal pan;
FIGS. 2 and 3 are perspective views of a still further embodiments of the toilet device of the present invention comprising modified urinal pans; and

DETAILED DESCRIPTION
This invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways. Also, the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of “including,” “comprising,” or “having,” “containing”, “involving”, and variations thereof herein, is meant to encompass the items listed thereafter and equivalents thereof as well as additional items.
Referring to FIGS. 1-3, these illustrate the toilet device of this invention having a modified urinal pans. In FIG. 1 the toilet device comprises a urinal pan 4c comprising sides formed by a sheet 22 (e.g. a urine-resistant cloth or plastic sheet) its bottom edge attached to the platform 2 and its upper edge attached to the rinse hose 16. The platform 2 has an opening 3, and the platform 2 is placed with the opening 3 over the toilet bowl 1. Legs 20 support the platform over the bowl 1. In FIG. 1, it is seen that the hose 16 includes the nozzles 24 to help rinse the urinal pan 4c, and one or more handles 26 for raising it so as to form the walls of thereof. In FIGS. 2-3, the rinse hose 16 supports the front and side walls to be pivotably adjustable between an operative position where the front and side walls are raised (FIG. 3) and an inoperative position where the front and side walls are not raised (FIG. 2). The device includes a water inlet pipe 17 and may include a main valve 28 and/or an automatic valve 30, or a pair thereof. Automatic valve 30 is detailed below with reference to FIG. 4.
Such a urinal pan may be held in its operative (upright) position by a variety of mechanisms; one such mechanism illustrated in FIGS. 2 and 3 wherein there is shown a urinal pan 4d that is similar to urinal pan 4c, however it comprises a cover 32. Not only is such a cover typically more aesthetic, the handles 26 can be attached thereto for raising the urinal pan 4d and further be used to fold the cover 32 backward (FIG. 3) whereby the cover's free edge can rest at a support bar 34, thus holding the pan 4d in an operative position.
FIG. 4 shows the platform mounted pivotally by hinge 19B and a view of the automatic valve 30 wherein it is seen that it comprises a member or valve handle 36 that interfaces with the underside of the platform 2. With such configuration, when the urinal pan 4c is lifted and put into its operative position, the valve handle 36 is automatically turned, typically about 30 to 45 degrees, and the automatic valve 30 is opened to supply water for rinsing the pan. Upon returning the pan to its inoperative position, the handle 36 is turned in reverse and the automatic valve 30 is closed.
It should be understood that there are various devices for facilitating defecation in a natural squatting posture that can be devised according to the present invention and that the above description is merely explanatory. Thus, the present toilet device can be embodied in a variety of aspects falling within the scope of the present invention, mutatis mutandis.
Having thus described several aspects of at least one embodiment of this invention, it is to be appreciated various alterations, modifications, and improvements will readily occur to those skilled in the art. Such alterations, modifications, and improvements are intended to be part of this disclosure, and are intended to be within the spirit and scope of the invention. Accordingly, the foregoing description and drawings are by way of example only.
