A dual flush cistern mechanism for an internal cistern to be mounted within a frame wall comprising a front and a rear layer spaced apart by, and secured to, a plurality of substantially vertical studs, the cistern being mounted between an adjacent pair of studs, having a maximum side-to-side dimension less than, or equal to, the spacing between said pair of studs, and having a maximum front-to-rear dimension less than, or equal to, the interior spacing between said front and rear layers, said mechanism comprising a flush tube 20 with a flush valve at its lower end and being selectively liftable by either one of a pair of pivoted flush actuating levers 38, and a knock down float 23 slidably mounted on said flush tube and latchable into an upper position by a pivotally mounted latch arm 25, wherein said flush activating levers and latch arm are each pivotal within a substantially vertical plane which is substantially parallel to said front and rear layers and wherein the pivots 37 for said actuating levers and latch arm have a pivot axis which is substantially normal to said vertical plane. <IMAGE> |
