BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention is in the field of floor protection and cleaning in male toilets.
A common problem in male toilets the world over is that of soiled floors, especially in the area around urinal stalls. Frequent cleaning is required to prevent the floors from becoming unhygienic, unsightly and unaesthetic. Such cleaning is expensive in labour costs and does not totally solve the problem. The action of uric acid on many of the more commonly used floor finishes results in unsightly discolouration within a short period of time and the eventual breaking down of the flooring materials necessitating their replacement at fairly frequent intervals. This is both expensive and disruptive.
PRIOR ART--GB-A-1,353,504
GB-A-1,353,504 in the name Regency Stainless Limited relates to urinals of the kind comprising a back wall which merges at the bottom into a trough fitted with a waste outlet, a sparge arrangement being provided at or near the top of the back wall to enable flushing water to be supplied to the front face of this wall and thence to the trough.
The patent teaches that in earlier constructions of urinals of this type, the trough is relatively narrow and a solid platform, on which users stand, is arranged immediately in front of it.
The patent teaches that such earlier constructions suffer from the drawback that the platform frequently becomes wet with spillage which can then be carried by the shoes of the users on to the floor area of the room in which the urinal is installed, thus giving rise to the creation of unhygienic conditions as well as to possible damage to floor coverings.
The patent teaches that a further drawback that arises with the known constructions is that the presence of the projecting platform, especially when this is made in one piece with the trough as is usually the case, frequently gives rise to difficulties in reaching the waste outlet for the purpose of coupling a waste pipe to it during installation of the urinal.
The patent then discloses a urinal which comprises a back wall, two side walls projecting forwardly from the ends of the back wall, a trough extending between the bottom parts of the side walls and projecting forwardly from the bottom part of the back wall, the trough having a base and an upwardly projecting front wall portion, a waste outlet formed in the base of the trough and positioned adjacent to the front wall portion thereof, a sparge device arranged at or near the top of the back wall and through which flushing water may be supplied to the front face of the back wall and thence to the interior of the trough, and an openwork, grating to enable a user of the urinal to freely stand thereon and which extends over the front part of the trough and is spaced above the base thereof, the grating being of such width when measured between its front and rear edges, compared with the width of the trough when measured in the same direction, that an uninterrupted opening is left between the rear edge of the grating and the front face of the back wall of the urinal.
The patent then describes and illustrates two embodiments which are substantially similar, differing only in the manner in which the grating is mounted over the trough. In both embodiments the floor of the trough is inclined downwardly in the direction away from the back wall and the flushing system consists of water flowing down the front face of the back wall and continuing down the inclined trough and draining out through a drain hole located at the front of and to one side of the trough beneath the grating. In both embodiments the floor of the trough is also inclined from side to side, sloping downwardly towards that side where the drain hole is located.
The arrangement described above suffers from a significant disadvantage. All of the urine, including that which has been correctly directed at the urinal back wall, is swept along the floor of the trough beneath the person standing on the grating. It will be apparent that this may give rise to strong odours.
A further disadvantage is t
