Definitions

  • This invention relates to a lavatory unit, more particularly to such a unit in the form of a female urinal.
  • Standard w.c. units require a good deal of space when compared with the space required by male urinals.
  • Standard w.c. units require a cistern which takes up space and which generally expends a large amount more water for a single flush than a male urinal. Accordingly it would be advantageous to have a female urinal which is more economical, uses less water and occupies less space than a w.c unit.
  • a female urinal comprising an open-topped receptacle for receiving urine, a water supply pipe including a timer valve, an overflow container into which water from the supply pipe is discharged when the valve is open, and means for directing water overflowing from said container under gravity to the interior rim of the receptacle to flush it.
  • a timer valve is a type of valve which is opened by operation of a manual actuator, such as a push-button or lever, and, when released, automatically closes after a certain period of time. They are commonly used in public washrooms instead of conventional taps to avoid water wastage by users forgetting to turn off the tap.
  • a manual actuator such as a push-button or lever
  • One type of timer valve is known as a non-concussive self-closing valve.
  • a female urinal comprises an open-topped receptacle 10, hereinafter referred to as a bowl, for receiving urine.
  • the bowl 10 is mounted in a cabinet or housing 12 and has a conventional liquid waste system 13 (shown in dotted outline). Access to the waste system is via a removable panel 14 in the side of the cabinet. The remainder of the plumbing is hidden by front and top panels 12a,12b.
  • FIG. 2 the urinal can be seen with panels 12a,12b removed.
  • An outer container or tank 16 is mounted above and to the rear of the bowl 10, and contains a relatively small inner overflow container 18.
  • a plurality of pipes 20 lead from the base of the outer container 16 to locations spaced around the interior rim of the bowl 10.
  • a water supply pipe 22 includes a non-concussive push-button valve 24 and, when the valve 24 is open, water from the supply pipe 22 is discharged into the overflow container 18.
  • the water supply pipe 22 is connected to any convenient source of water, for example a header tank for a bank of such urinals or the general water supply for the building.
  • the urinal is independent of any particular type of water supply.
  • the push-button on the valve 24 is pressed in. This releases a certain volume of water, determined by the "on" period of the valve 24, the water supply pressure and the diameter of the pipe 22, into the overflow container 18. Typically the valve 24 would be set to supply 2 litres of water. Water overflowing from the latter flows into the outer container 16 and then down through the pipes 20 to the interior rim of the bowl 10 where the water exits from the pipes 20 to flush the bowl.
  • the cabinet 12 is shown mounted on a pedestal 26, the height of which may be varied to suit different groups of users. For example, in a school environment, a lower pedestal or no pedestal may be used, for accessibility by children.
  • the urinal may alternatively be mounted against a wall such as on cantilever brackets. Alternatively, the urinal may be provided as a portable unit for temporary connection to a water supply and waste outlet.
  • Fig. 3 shows the plumbing detail of a second embodiment of the invention, i.e. the cabinet and bowl are omitted and the components shown are equivalent to the tank 16, overflow container 18, pipes 20, supply pipe 22 and valve 24 of the embodiments of Figs. 1 and 2.
  • the embodiment of Fig. 3 has a supply pipe 122 and non-concussive valve 124 as in the first embodiment.
  • a tank 116 again receives a fixed volume of water from the supply pipe 122.
  • a perforated sidewall 130 divides the tank 116 into two containers, namely an overflow container 132 and a secondary container 134.
  • a pair of pipes 136 run from the bottom of secondary container 134 to a ring 138 formed of perforated pipe.
  • valve 124 is actuated by the user causing 2 litres of water to flow into overflow container 132.
  • the water immediately begins to drain through the perforations 140 in sidewall 130 into the secondary container 134. From there the water drains through the pipes 136 into the ring 138. Drainage holes 142 in the ring 138 cause the water to run down the sides of the bowl (not shown in Fig. 3).
  • Figs. 4 and 6 show the ring 138 in place in a bowl 110.
  • the drainage holes 142 are disposed on the outer side of the ring, below the centreline, such that when in place in a bowl, the water is directed onto the surface of the bowl near the internal rim 144. From there the water drains to a central waste pipe 113.
  • a cover 146 fits over the internal rim 144 to hide the ring 138 from view.
  • the cover comprises an outer frame 148 defining a central aperture. The user sits on the frame 148 when urinating. Because the urinal is not designed to receive solid waste a convex cut-out 150 at the rear of the frame is intended to inhibit defecation and a concave cut-out 152 at the front provides greater access for urination.
