<p>A water closet (WC) or toilet bowl usable in either in the: 1 ) sitting, 2) front facing squatting, or 3) rear facing squatting postures. The WC consists of an elongated receptacle (10) similar in ratio of length to width to an eastern squatting-type WC, with shrouds (11 ) at each end to contain urine spray and footrests on each side, at a slightly lower level than the receptacle, but at such a height above the floor that mounting the footrests is not uncomfortably precarious. The volume below the receptacle and footrests is used for a cistern, fed from a normal pressurised water supply, so that the flush water source is near the siphon jet entrance at the front part of the S-bend. A hinged seat, of suitable thickness / height so that when folded down and resting on the receptacle, forms a suitably high ring-shaped sitting surface.</p> |
