BACKGROUND OF THE INVENTION
Squatting toilet device is the only natural defecation posture for the human being and accordingly to recent research it prevents many medical problems. However the main hygienic problem of existing squatting devices is the soiling by the urine of the platform as well as user's feet and clothes. Recently was invented squatting device which includes an urinal (U.S. Pat. No. 7,962,973 B2) pan to resolve the above problem. The significant drawback of the citated Patent is connected with converting of the pan from nonfunctional to functional position and vice versa. In the above US Patent it is done by complex rotation movement by means of the cover of the pan. Such rotation movement is to complex and some person will be unable to perform it. Accordingly a new aquatting device was invented.
SUMMARY OF THE INVENTION
A combined toilet device for defecation in a natural squatting defecation posture and having a platform to support a user in the squatting defecation posture over its opening aligned with the toilet bowl, said device comprises an urinal pan to prevent urine dispersion, the frame of the said urinal pan is formed by a pipe arc having a long and short parts, said pipe arc, wherein the parts of pipe arc continues one into another, said pipe arc, wherein long and short parts are at different planes with 90 grade between them, short and long parts of the said pipe arc serves for converting of the urinal pan to functional or nonfunctional position, said pipe arc wherein a flexible material is attached continuously to the said pipe arc forming walls of urinal bag (namely of the urinal pan) opened in the direction of a squatting men, said flexible material is a silicone or rubber or similar materials permitting to prepare a urinal bag of desirable shape by appropriate mold, said pipe arc wherein its free ends of the rear part is attached pivotally to the platform at the area of front part of the opening, said long and short parts of the urinal pan are in different planes with 90 grade between them thus forming a depth in the urinal bag what prevent the urine stream rebounding on the user, said squatting device includes a cover of urinal pan formed from two plastic leafs which cover the urinal pan in a nonfunctional position, said plastic leaves are attached pivotally to the platform one at either side of the pan, said plastic leafs are attached to the platform by axles which contains springs.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG. 1-5 there is shown a combined toilet device for mounting over a toilet bowl (1). The device comprises a platform (2) having an opening (3) aligned with the opening of the toilet bowl. The platform constructed in a planner shape for supporting of a user in a squatting posture over said opening. The device includes an urinal pan, which is shown in a functional position in FIG. 2. As is well known the urinary sphincter is opened reflectory after defecation and urine is discharged. The urinal pan prevent dispersion of urine and soiling of the platform and legs and clothes of the user. The urinal pan when in a nonfuctional horizontal position occupy the middle part of the platform from the opening to the front edge of the platform. In FIG. 1 the urinal pan is in a nonfunctional horizontal position, the pan is not seen as it is hidden by the cover 4.
The aim of the cover is to prevent destruction of the urinal pan while the user rises on the squatting device for assuming of the squatting position. The cover is combined from two plastic leafs 5 as is shown in FIG. 1-3, which are cover the urinal pan in a nonfunctional position and are attached pivotally to the platform at either side of urinal pan by axles 6 as is illustrated FIG. 1-2. In the axles 6 are included springs 7. The leafs of the cover may be from firm plastic material strong enough to maintain the men's body.
The frame of the urinal pan is formed by a pipe arc as is shown in FIG. 2-4 which is combined from two continuous parts, short (8) and long (9) one. In partial view in FIG. 4 is illustrated the pipe arc in a nonfunctional position wherein the long part (9) of the pipe arc is in the horizontal plane and immediately beyond the front edge of the platform is bend by 90 grade downward thus forming the short part (8). The short part 8 of the pipe arc serves as a handle for pivoting the urinal pan from folded nonfunctional as is in FIG. 3-4 to functional position as in FIG. 2. The user can lift the short part 8 and pull it in its direction. Pushing down the long part 9 of the pipe arc pivot the urinal pan from functional position as illustrated in FIG. 2 to nonfunctional position as is illustrated in FIG. 3-4.
FIG. 4 is a partial view showing only the pipe arc in a nonfuctional horizontal position. The both ends, the free ends 10 of the rear part of the pipe arc are bent outside with one or both of them attached to water source (not shown). Just at this bending both ends of the pipe arc are attached pivotally by a ring 11 to the platform in vicinity of front part of the opening 3.
As is shown in FIG. 2 a flexible material (12) is attached to external surface of pipe arc continuously on all length of long and short parts of the pipe arc forming a front, side and bottom walls of urinal pan thus creating a urinal bag opened in the direction of a squatting man. As the long and short portions of the pipe arc are in different planes with 90 grades between them just attaching of any flexible material to pipe arc will create folds preventing effective washing of walls interior of the pan. To overcome this obstacle it may be used materials such as silicone, rubber or similar materials that may form any desirable shape of urine bag by means of appropriate mold.
As the long and short parts of the urinal pan are in different planes with 90 grade between them a depth is created in urinal bag as is illustrated in FIG. 2. That is, the front wall of urinary bag is faraway from the user thus preventing the urine stream rebounding on the user but at the same time permit to move the urinal pan as close as possible to the user's opening of the urethra. It is found in preliminary tests that dispersion of urine may be prevented only when the urinal pan is moved maximally close to urethral opening.
When the urinal pan is converted to functional position as is in FIG. 2 the leafs of the cover are pushed aside but the springs in the axles of leafs cause resistance by pressing on the pipe arc namely on the urinal pan and thus may fixate the pan at any desirable point, for example point 13 of specific user. The angle of the squatting posture of different persons is different and accordingly the necessary distance of urinal pan from body of specific user will be different. The user may move the pan to any desirable position while the pressure of cover leafs on urinal pan will ensure such position.
The pipe arc serves for leading water to wash the internal parts of the walls of the pan through nozzles 14 which are found continuously along short and long parts as illustrated in FIG. 2.
Thus the pipe arc fulfill several function: It is used as a frame to which attached flexible material for forming the urine walls, lead the water to wash the internal parts of walls from residual urine, pivot the urinal pan from nonfunctional to functional position and vice versa.
The cover as well fulfils several function. It prevent destruction of urinal pan when the squatting posture is assumed, the leafs of the cover can fixate the urinal pan at any desirable point, the cover is fulfill also esthetic role.
The platform mounted pivotally hinges 15 as is shown in FIG. 5 to the rear part of the toilet bowl. Two or more legs 16 are fixed or attached pivotally to underneath of the platform as is shown in FIG. 2,4,5 for supporting the platform and the user on it.
