  • FIGS 1 to 5 there is shown an improved toilet cistern 10 comprising a housing 12 and a first tank 14, and a second tank 16.
  • An upper portion 18 of the housing 12 has provided thereon a removable lid or cover 20.
  • a lower portion 22 of the housing 12 is provided in the form of a funnel to direct flushing liquid, for example water, towards an outlet 24 which in use is connected to a down pipe (not shown), which is further in turn connected to a toilet pan (not shown).
  • the housing 12 is further provided with a front wall 26, side walls 28 and a rear wall 30. Both the front wall 26 and the rear wall 30 have provided therein an externally recessed portion 32, best seen in Figure 1. The recessed portion 32 of the rear wall 30 has provided therein an aperture 34.
  • a flow control means 36 is provided in association with the improved cistern 10 and comprises a flushing fluid inlet pipe 38, and inlet valve 40, a flushing fluid transfer pipe 42 and a flow directing member 44 located within the housing 12.
  • the inlet valve 40 is actuable directly or indirectly by an elongate actuation member 46 that is pivotally connected to an arm 48 of an oscillating member 50.
  • the elongate actuation member 46 extends between the oscillating member 50 and the inlet valve 40, projecting through the aperture 34 defined in the recessed portion 32 of the rear wall 30.
  • a mounting frame or member 52 is locatable within the housing 12, as is best seen in Figure 1.
  • the mounting member 52 comprises two substantially opposed end plates 54 and an intermediate plate 56.
  • the end plates 54 are each able to locate positively within the recessed portions 32 of the front wall 26 and rear wall 30 of the housing 12.
  • Each end plate 54 has provided therein a pair of locating slots 58.
  • the locating slots 58 are provided in a form whereby a stud member 60 provided on each tank 14 or 16 may be slidably and rotatably received therein. Further, the slots 58 are arranged such that the weight of the tanks 14 and 16 holds the stud members 60 within the slots. The removal of the stud member 60 from the slots requiring that the tanks 14 and 16 be lifted by a user (not shown) both upward and outwardly with respect to the mounting member 52.
  • the rearwardly located end plate 54 of the mounting member 52 further has provided thereon a tab member 62.
  • the tab member 62 has a pivotal mounting spigot 64 projecting therefrom and on which is located the oscillating member 50 in a pivotal manner.
  • the oscillating member 50 further comprises a float arm 66, the float arm 66 being arranged to project over the second tank 16 when assembled, as is best seen in Figures 2 to 5.
  • the intermediate plate 56 of the mounting member 52 has located on an upper edge 68 thereof a flushing liquid flow channel 70, oriented to facilitate flushing liquid flow transversely thereacross.
  • the cover 20 is proportioned so as to engage the open upper portion 18 of the housing 12.
  • a means for discharging the tanks 14 and 16 is mounted rotatably through the cover 20. This means is provided in part in the form of a rotatable knob 72 accessible by a user of the improved toilet cistern 10.
  • a shaft 74 depends from the knob 72 and projects through the cover 20.
  • a tank engaging member 76 is provided at the lowermost extremity of the shaft 74 and is arranged so as to be in use adjacent both the tanks 14 and 16 when such are in a filling or filled position. Further, the tank engaging member 76 is proportioned such that when the knob 72 and shaft 74 are rotated in one direction only tank 16 is engaged thereby and caused to discharge its contents.
  • Each tank 14 and 16 comprises an outer wall 78 and an internal wall 80.
  • the outer wall 78 defines generally the tank 14 or 16 and has an open top.
  • the intemal wall 80 extends from a base of the tank 14 or 16 upwardly but does not project fully to the open top thereof.
  • the internal wall 80 thereby divides each tank 14 and 16 into a first chamber 82 and a second chamber 84. Due to the height of the internal wall 80 liquid may flow from one chamber into the other within each tank 14 or 16, before flowing from that tank.
  • the first tank 14 has provided therein a flow chute 86 arranged to accept liquid flow from the flow directing member 44 into the first chamber 82.
  • a recess 88 is provided in the outer wall 78 of the tank 14 adjacent the first chamber 82 thereof.
  • the recess 88 is provided with a lip 90 arranged so as to engage the flow channel 70 of the intermediate plate 56 of the mounting member 52. In this manner, overflow from the first tank 14 is directed through the recess 88, over the lip 90 and across the flow channel 70 to the first chamber 82 of the second tank 16.
  • a float means 92 comprising a float housing 94 in which is movably received a float member 96.
  • the float housing 94 is affixed to the inner wall 80 of the second tank 16, as is best seen in Figures 2 to 5.
  • the float member 92 has provided thereon an upwardly projecting engaging arm 98.
  • the engaging arm 98 is arranged to engage the float engaging arm 66 of the oscillating member 50 as is again best seen in Figures 2 to 5.
  • the user (not shown) will chose between a half flush or a full flush from the improved toilet cistern 10. If the user selects a half flush then he or she will rotate the knob 72 in the direction indicated by arrow A in Figure 3.
  • the tank engaging member 76 rotates accordingly and impinges upon the outer wall 78 of the second tank 16.
  • This action causes the second tank 16 to rotate or pivot about the stud member 60 and the weight of the flushing liquid held within the second tank 16 causes an over-centre action resulting in the spilling of the flushing liquid from the second tank 16, as indicated by arrows B in Figure 3.
  • the discharged flushing liquid flows downwardly within the housing 12 and the funnel shaped lower portion 22 thereof directs the discharged flushing liquid towards the outlet 24.
  • the discharged flushing liquid in turn progresses to the down pipe (not shown) and toilet pan (not shown) to effect a flushing action therein.
  • the rotation of the second tank 16 as shown in Figure 3 causes the disengagement of the float member 92 and its engaging arm 98 from the float arm 66 of the oscillating member 50.
  • the inlet valve 40 has been opened through the action of the elongate actuation member and the arm 48 of the oscillating member 50.
  • the weight of the float arm 66 of the oscillating member 50 is such that it will cause the oscillating arm 50 to pivot about the pivotal mounting spigot 64 causing a raising of the arm 48.
  • This raising of the arm 48 is in turn transferred through the elongate gate actuation member 46 to the inlet valve 40 to actuate or open same.
  • flushing liquid is shown entering the housing 12 through the flow directing member 44. This flow is directed firstly into the first tank 14. As the first tank 14 had not been discharged the flushing fluid entering same is caused to overflow through the recess 88, over the lip 90 and across the flow channel 70 to the first chamber 82 of the second tank 16. As the first chamber 82 of the second tank 16 fills the flushing fluid will overflow into the second chamber 84, in turn filling the second tank 16. As the second tank 16 fills the float member 92 is raised within the float housing 94 and the upwardly projecting engaging arm 98 abuts the float arm 66.
  • the upward force exerted by the float member 92 is sufficient to overcome the weighted nature of the float arm 66 and causes the oscillating member 50 to pivot back about the pivotal mounting spigot 64 and in turn shutting off the inlet valve 40. As such, the flow or flushing fluid through the water transfer pipe 42 to the flow directing member 44 is shut-off.
  • the improved toilet cistern 10 subsequently adopts the appearance as shown in Figure 2, in which both tanks 14 and 16 are full of flushing liquid. If the user requires a full flush the knob 72 of the discharging means is rotated in the direction of arrow C shown in Figure 5. This action causes consequent rotation in the shaft 74 and the tank engaging member 76.
  • the tank engaging member 76 is proportioned such that upon rotation in the direction of arrow C it impinges upon both tanks 14 and 16, thereby causing both tanks 14 and 16 to rotate about their stud members 60 and consequently over-balance and discharge the flushing liquid therefrom.
  • the discharge of the second tank 16 has been described hereinabove.
  • the first tank 14 is caused to discharge after its outer wall 78 is abutted by the tank engaging member 76 causing its rotation and over-balancing about the stud members 60 held rotatably within the slots 58 of the mounting member 52.
  • the weight of the flushing liquid within the first tank 14 helps its continued rotation about the stud member 60 which in turn results in the discharge of the flushing liquid in accordance with arrows D shown in Figure 5.
  • the flushing liquid flows into the housing 12, downwardly through the funnel shaped lower portion 22 and in turn to the outlet 24.
  • the flushing liquid then in turn passes through the down pipe (not shown) to the toilet pan (not shown) where the flushing action is achieved.
  • the construction of the tanks 14 and 16 is such that upon discharge of the flushing liquid therefrom they rotate back under their own weight into a substantially upright position such that flushing liquid entering the housing 12 may be received, firstly within the first tank 14, and in turn in the second tank 16.
  • the inlet valve 40 is actuated through disengagement of the float member 92 from the float arm 66 of the oscillating member 50, as described hereinbefore. Flushing fluid flows into the housing 12 through the flow distribution member 44 and onto the flow chute
  • Flushing liquid flows along the flow chute 86 and into the first compartment
  • the improved toilet cistern 10 of the present invention consequently avoids the use of an underwater valve to produce the head of water required to cause a flush of flushing liquid for a typical prior art toilet cistern. Consequently, the problems of leakage of water and the consequent need to repair or replace valves is avoided. Additionally, the high noise levels associated with the refilling of siphonic toilet cisterns and underwater valve cisterns are also avoided.
  • the tanks 14 and 16 may be provided in either the same or different capacity.
  • one embodiment may have both tanks 14 and 16 provided with a three litre capacity, thereby providing a half flush of three litres and a full flush of six litres.
  • further embodiments may have differing capacities, such as one four litre tank and a second two litre tank such that a half flush of either two or four litres may be provided, with a full flush of six litres.
  • the tanks 14 and 16 are preferably mounted in the offset manner discussed in the above embodiment of the improved toilet cistern 10. However, it is to be understood that the tanks 14 and 16 may be provided at the same height relative to the housing 12. However, this will require the provision of multiple flushing liquid level sensing means, which means is achieved by way of the float member 92 in the above discussed embodiment.
  • the tanks 14 and 16 are mounted in the mounting member 52 such that when full of flushing liquid they tend to adopt the upright position disclosed in Figure 2.
  • the tanks 14 and 16 may be mounted and balanced in a "tend to tip" position such that when full they are inclined to rotate about their pivotal mounting.
  • a latching means will be required to hold the tanks 14 and 16 in an upright position. The release of the or each latch so provided will act to release the tanks 14 and 16, thereby discharging the flushing liquid contained therein.

  • the or each tank of the improved toilet cistern may be balanced in the inclined to tip position described above without any latching means.
  • the flow rate of flushing liquid entering the cistern housing may then be set to fill the or each tank at the desired time interval, thereby causing the or each tank to discharge its flushing liquid contents at the required time interval.
