Definitions

  • the present invention relates to a flush tank or cistern structure particularly for the controlled and differentiated washing of toilet bowls in sanitary fittings and the like.
  • flush cisterns or tanks for cleaning toilet bowls are currently known and used, and are usually constituted by a water container which is connected to the water mains, has automatic means for controlling the supply from the mains to the container and is provided with a duct, defined on the bottom of the container, for discharging the water toward toilet bowls.
  • the duct is connected to a bowl by means of a pipe, and the discharge of water is controlled by means of a plug which can be disengaged by means of lever systems which are actuated manually from the outside every time the toilet bowl is washed.
  • Cisterns which perform the differentiated washing of toilet bowls are also known; said cisterns have differentiated controls for the discharge of preset amounts of water as a consequence of the use of one or more external controls. Said cisterns constitute a considerable improvement with respect to the preceding ones, said improvement being essentially related to the water saving achieved by rationing the discharge of the water. Also known from DE-A-2,601,282 is a flush tank structure as defined in the precharacterizing part of claim 1.
  • Known devices usually have a discharge control structure which has an overflow pipe which is connected directly to the duct of the cistern, and on which two ports are defined at differentiated heights; said ports are opened and closed by means of respective plugs, each of which is actuated by lever systems connected to external manual actuation means.
  • the aim of the present invention is to eliminate or substantially reduce the disadvantages described above in known types of cisterns.
  • This aim is according to the invention achieved by providing a flush tank structure as defined in claim 1, preferred embodiments of the invention are defined in the appended dependent claims.
  • an object of the present invention is to provide a flush tank structure which is highly reliable in operation and is much quieter and more precise in discharge control than currently installed and mounted cisterns.
  • Not least object of the present invention is to provide a flush tank structure which is relatively easy to manufacture and at competitive costs.
  • a traction element 5 is inserted in the port 3 and supports the sealing plug 4; the traction element 5 extends upward, passing through a compensation chamber 6, and has, on its free terminal end 7, lifting means which are connected to external actuation means by means of lever systems.
  • the lifting means comprise adjustment means for the complete or partial discharge of the water from the cistern, so as to allow controlled emissions of washing water according to the different requirements.
  • the compensation chamber 6 has, at its base, a plurality of pathways 40 for the unobstructed free flow of water toward the port 3.
  • the lifting means for partial discharge are constituted by an annular body 8 which is inserted and fixed on the traction element 5, which has means for detachable engagement with the adjustment means.
  • the annular body 8 is connected to a first lever system by means of a first bracket 9.
  • the first lever system is composed of a support 10 which is fixed on an inner wall of the flush tank 1 and has a plurality of supporting seats 11.
  • a first lever 12 is pivoted on one of the supporting seats 11 and is directly connected to the external actuation means, for example an actuation pushbutton 13 which protrudes from the flush tank 1.
  • the first lever 12 bears a removable engagement means for a second lever 14 which is pivoted, at an end portion, in another one of the supporting seats 11, which is inserted within the first bracket 9 with its other terminal portion, and which bears guiding means for the removable engagement means.
  • the removable engagement means is constituted by a hook 15 which is mounted so as to rotate angularly on the free end portion of the first lever 12 and is kept in position by means of a snap ring 16.
  • the guiding means of the second lever 14 are constituted by an inclined segment 17 which rises from the second lever 14 at the hook 15 which is mounted on the first lever 12, so as to facilitate the engagement of said hook 15 with the second lever 14.
  • the lifting means for complete discharge are constituted by a sliding ring 18 which is inserted on the traction element 5.
  • the ring 18 is connected to a respective second lever system by means of a second bracket 20, and such ring has a bracket-shaped base perimeter within which grip seats 25 for the tabs 19 are defined.
  • the second lever system is composed of a support 21 which is fixed on an internal wall of the flush tank 1 and which has a plurality of supporting seats 22.
  • a third lever 23 is pivoted on one of said supporting seats 22 and is connected directly to external actuation means, for example an actuation pushbutton 24 which protrudes from the flush tank 1.
  • the free end portion of said third lever 23 is inserted within the second bracket 20.
  • the adjustment means for partial or complete discharge are constituted by an annular weight 26 which is slidingly inserted on the traction element 5 and rests on the chamber 6.
  • the weight 26 has raised engagement portions 27 for detachable engagement means which will be described hereinafter, and an annular containment compartment 28 for water in order to increase its own weight.
  • a plurality of water discharge holes 29 is defined in the lower surface of the annular compartment 28 so as to avoid creating water stagnation regions in the flush tank 1.
  • the detachable engagement means are constituted by levers 30, each of which has, on a terminal portion, an abutment 31 for engaging the annular weight 26 and, on its other terminal portion, an opposite tab 19 engaged by the sliding ring 18 upon its upward movement thereof.
  • the levers 30 are pivoted within the annular body 8 and can perform an angular rotation.
  • the traction element 5 is constituted by an overflow pipe which, if the water exceeds the overflow level of the flush tank 1, discharges the excess water into the port 3.
  • the first lever 12 is actuated and, by means of the hook 15, raises the second lever 14.
  • the lifting of the second lever 14 entails the lifting of the traction element 5 by means of the first bracket 9, thus lifting the plug 4 and opening the port 3.
  • the duration of the partial discharge i.e. the amount of water discharged, is adjusted by the release of the hook 15 from the second lever 14.
  • the hook 15 unhooks from the second lever 14, since by rotating about the lever 12 it disengages from the lever 14. Once unhooking has occurred, the second lever 14 is free, and the weight 26 causes the immediate closure of the port 3 by means of the plug 4, pushing the traction element 5 downward, due to the greater weight of the weight 26, which can be made of a much heavier material than the traction element, and also due to the water stored in the annular compartment 28.
  • the holes 29 are required in order to avoid prolonged storing of water within the annular compartment 28.
