Definitions

  • the present invention relates to an economising device for toilet cisterns.
  • the present invention relates to a device for toilet cisterns provided with means suitable to limit - if needed - the water flow from the cistern into the underlying toilet bowl to which it is connected.
  • the traditional toilet groups installed in bath-rooms or service rooms comprise a toilet bowl to which an overlying cistern is associated, which cistern is the water collection tank, fed by the mains.
  • Cisterns either or sight on fitted into the wall, comprise a waste valve, controlled through lever-systems activated generally by a push-button protruding from said cisterns; the latter contains also a float ball with a faucet suitable to stop the water flow in the cisterns once the prefixed liquid level has been reached.
  • the cisterns of the known art which provide for the possibility of a differentiated water waste generally include mechanisms that are very complex from the point of view of construction, and whose activation is awkward, which involves high costs for their realisation and difficulties in regulation and maintenance.
  • Object of this invention is to obviate the above drawbacks.
  • AU-A-580 783 discloses an economising device for toilet cisterns as defined in the preamble of claim 1.
  • object of the invention is to provide an economising device for toilet cisterns such as to allow a water flow in alternative and calibrated amounts, without the need of complex or awkward interventions by users.
  • a further object of the invention is to provide an economising device as defined above, wherein the supply of a partial amount of water in the bowl is obtained directly and following one only intervention by users.
  • a further object of the invention is to provide an economising device for toilet cisterns that can always ensure a high level of resistance and reliability in the time.
  • the economising device of the present invention basically comprises a primary lever-system 10, associated to a push-button 12, a secondary lever-system 14 associated to a second push-button 16, and a waste valve 18 of a known type, located in correspondence of the lower opening of the toilet cistern, axially sliding in the same.
  • the primary lever-system 10 is constituted, according to a preferred non critical embodiment, by a plurality of arms connected and articulated with one another, moved through push-button 12.
  • said lever-system 10 comprises a first arm 20, connected on the one side with push-button 12, and on the opposite side, with a second arm 22; the connection between said arms is of the articulated type, to allow the angle orientation of the same, progressively variable, under the effect of the pressure exercised from up downwards on said push-button 12.
  • a fulcrum element is formed, while an extension 26, having the form of a cylindrical pawl or other suitable form, protruding for a limited extent on at least one side, is integral with arm 22.
  • a further arm or tierod 20 articulatably connected to a horizontal branch 30 of lever-system 10; said branch 30 is connected with its free end to valve 18 of the toilet cistern (not represented).
  • the whole of arms 20, 22, 28 and branch 30, which form altogether the primary lever-system 10 of the economising device of the present invention is incorporated in an envelope from plastic material which is installed in the toilet cistern; there protrudes from it the free end of arm 20, which is connected, through means known in themselves, for instance quick hooks, to the lower end 12' of push-button 12, and branch 30, entirely or partly, which is connected to valve 18.
  • Figure 1 which represents schematically the economising device, shows the exemplifying orientation of said arms 20, 22, 28 and branch 30, which in the resting position, i.e.
  • arm 20 is connected to push-button 20 and is orthogonally arranged with respect to said branch 30 and arm 20, while the intermediate arm 22 is diagonally oriented, at an angle comprised, by way of example, between 30 and 60°.
  • the fulcrum element 24 is constituted by an extension obtained integrally with one of the inner walls of an envelope (not represented) containing the whole device.
  • the secondary lever-system 14 is constituted by a lever-system or stiff arm formed by sectors angularly oriented relatively to one another, and is placed on a lower plane with respect to the primary lever-system 10.
  • lever-system or arm 14 comprises a first portion or branch 32 connected with the lower end 16' of push-button 16, near push-button 12, an intermediate branch 34 and an end portion or branch 36, whose end is partly bent on itself upwards to define a hook or small spike 38.
  • the lever-system 14 defines a tendentially sinusoid orientation.
  • lever-system has the first branch 32 substantially parallel to arm 20 of the primary lever-system 10, the intermediate branch 14 inclined downwards at an angle comprised, by way of example, between 300 and 330° with respect to branch 32, and the end branch 36 angularly oriented upwards, to a reduced extent with respect to the angle of the preceding one.
  • Branch 36 is anyhow so oriented as to touch or to approach extension 26 of arm 22 also in conditions of non utilisation of the economising device.
  • Said configuration of lever-system 14 is, in any case, only an example, as it can have a mixed-linear development or a continuous concave-convex development.
  • a fulcrum element 40 is formed on which the same lever rests and tilts following the pressure exercised on push-button 16; said fulcrum 40 is advantageously constituted by an extension or pawl integral with at least one of the inner walls of the container which incorporates, just as the primary lever-system 10, also the secondary lever-system or lever 14.
  • a protrusion 42 constituted by an eyelet or the like, for hooking an end of an elastic means 44, such as for instance a helical spring; the opposite end of said elastic means 44 is anchored to a stable support 46, formed for instance by a hook or extension integral with one of the inner wall of the envelope wherein both lever-systems 10 and 14 are housed.
  • All the elements that constitute said lever-systems, i.e. arms 20, 22, 28, branch 30 and lever 14 are preferably from plastic material, for instance, PVC or other suitable materials, like the envelope (not represented) that incorporates them.
  • push-buttons 12, 16 causes the flow into the underlying bowl of different amounts of liquid, as specified hereafter. If all of the water contained in the toilet cistern should be discharged, in order to perform an accurate cleaning of the bowl, there is activated push-button 12 connected to the primary lever-system 10; the compression of said push-button, whose end of stroke is determined by the maximum possible lifting of the conventional waste valve 18, causes the articulated movement of the various arms 20, 22 and 28 and branch 30 of the primary lever-system 10, which takes up the configuration represented schematically in Figure 2.
  • arm 20 orientates angularly downwards, drawing upwards arm 22 to which it is articulated thanks to the support defined by fulcrum 24; consequently, also arm 28 lifts taking up an angular position outsidewards in the direction indicated by arrow A, and draws upwards branch 30 connected at one end with the waste valve 18.
  • the latter disengages then from the retaining seat and allows water to flow from the toilet cistern into the underlying bowl. In this case, these is a complete water flow, as said waste valve returns to its seat by gravity according to the conventional system.
  • the activation of push-button 12 does not affect in the least the secondary lever-system 14.
  • push-button 16 is activated, which is directly connected to the secondary lever-system 14 and indirectly to the primary lever-system 10.
  • the pressure exercised on push-button 16 causes first of all the tilting of lever 14, as shown in Figure 3; said lever, which meets fulcrum 40 in the connection portion between the first branch 32 and the intermediate branch 34 and meets systematically extension 26 of arm 22 with the end arm 36, lifts progressively and draws upwards also the lever-system 10, as schematised by arrow B of Figure 2 and, as a whole, in Figure 3.
  • the lifting action is exercised starting from pawl or protrusion 26, which is captured by the hook or small spike 38.
  • This movement causes the elements that form the lever-system 10 to take up the same configuration previously described and referred to the complete water discharge, but involves also the tensioning of the elastic member or spring 44, connected on the one side to lever 14 and, on the other side, to support 46, while the hooking of the extension or pawl 26, formed on arm 22 by hook 38 causes the end of stroke of the secondary lever-system or arm 14.
  • spring 44 contracts and draws downwards branch 22 of the primary lever-system 10 with what is connected to it, determining the closing of waste valve 18 and the ensuing interruption of the water flow, as also branch 30 lowers.
  • the secondary lever-system 14 that controls push-button 16 is advantageously provided with an arm 50 from plastic material, metal or other suitable materials on which a movable balance weight 52 is applied, by means of a threading or by a friction system or the like.
  • said arm 50 is constituted by a stem from plastic material having a continuous thread
  • the balance weight 52 is formed, according to a non critical embodiment, by a metal body, for instance from brass, for the calibrated and adjustable screwing on said stem.
  • Arm 50 carrying the balance weight 52 is brought to or integrally obtained with the front end of lever 36 and is located near hook 38 or in the vicinity of the same, not to interfere with the articulated means that form the primary lever-system 10.
  • said arm 50 and said balance weight 52 determine the variable supply of water from the toiler cistern according to the position of said balance weight 52.
  • the supply time reduces as the position of the balance weight 52 approaches the upper part of arm 50, and vice-versa; such adjustment may be advantageously obtained in a calibrated way either on the installation or afterwards.
  • the economising device for toilet cisterns of the present invention allows to alternately discharge variable amounts of water according to the specific needs.
  • Particularly advantageous is the possibility of causing the flow from the toilet cistern of a reduced and prefixed amount of water by simply acting on a push-button and activating it until the end of stroke point is reached, without the need of evaluating the time necessary for the operation.
