Definitions

  • the invention relates to a double-action flushing device for a water closet, provided with a valve which is moveable between a closing position in which it closes a discharge opening of a cistern, a full flushing position in which it leaves the discharge opening completely open and at least one intermediate flushing position, operating means connected to the valve, a main float co-acting with the valve for holding thereof in the intermediate flushing position and at least one auxiliary float co-acting with and holding the valve in the full flushing position.
  • a flushing device is known, for instance from the European patent specification EP-A-0 578 892 or the British patent specification GB-A-2 047 301.
  • Double-action flushing devices with which water consumption can be reduced have been applied increasingly in water closets in recent years. This is important in view of the increasing cost of the water supply.
  • a relatively small or a larger quantity of water can be supplied to the toilet bowl during a flushing by using such a double-action flushing device.
  • a relatively commonly applied flushing device makes use of a flush interrupting mechanism, with which a user can interrupt an already commenced flushing as he desires when in his opinion sufficient water has flushed through the toilet bowl to clean it adequately.
  • this flush interrupting mechanism requires a conscious effort on the part of the user, which is often overlooked, whereby a full flushing is still carried out and thus an unnecessarily large quantity of water is used and drained to the sewer.
  • the valve By moving an operating member to a first position the valve is raised over a first relatively small distance, whereby the protrusion is moved past the ratchet-like outer end of the first lever but not yet past the second lever.
  • This first lever is connected to the float which floats higher in the cistern. Because the valve is raised, water will flow out of the cistern through the thus cleared discharge opening, whereby the upper float will descend with the water level and cause the lever to pivot. At a determined height of water in the cistern the float will have descended so far and the lever pivoted so far that the ratchet-like outer end thereof moves out of engagement with the protrusion of the valve, whereby the valve drops back to its position closing the discharges opening. A partial flushing is thus effected.
  • the flushing will then only be ended when the second float arranged lower in the cistern has descended sufficiently, whereby a larger quantity of flushing water can flow out of the cistern and a full flushing is performed.
  • the invention therefore has for its object to provide a double-action flushing device of the above described type wherein these drawbacks do not occur.
  • the valve is in this way held open in that it is suspended from the float directly connected thereto instead of by a protrusion and ratchet mechanism.
  • At least one of the lever mechanisms can hereby be omitted, thus reducing the danger of malfunction as well as manufacturing costs.
  • a double-action flushing device 1 for a water closet is provided with a valve 2 which is moveable between a closing position (fig. 1) in which it closes a discharge opening 3 of a cistern 4, a full flushing position (fig. 3,4) in which it leaves the discharge opening 3 completely open and an intermediate flushing position (fig. 2).
  • the discharge opening 3 which is closed by valve 2 is arranged in the bottom 5 of the cistern 4 and communicates via a coupling piece 7 with a flush tube (not shown) leading to a toilet bowl.
  • the flushing device 1 further has operating means 10, which are connected to valve 2, in addition to a main float 8 which is connected to valve 2 and holds valve 2 in its intermediate flushing position, and an auxiliary float 9 which holds the valve 2 in its full flushing position.
  • the main float 8 is therein fixed to valve 2, while the auxiliary float 9 can be coupled directly to valve 2 by means of the operating means 10.
  • the operating means 10 comprise a push button 11 consisting of two parts 11A,11B which are moveable jointly as well as independently of each other.
  • Push button 11 is received in a housing 12 which is connected in turn to the cover 6 of cistern 4.
  • the lower end of push button 11 engages on a plunger rod 13 which is slidably received in housing 12 and provided on its bottom end with a protrusion 39 which co-acts with a lever 15.
  • the latter is arranged in a yoke 14 for pivoting round a shaft 16, which yoke 14 rests on legs 17 which are received in a base 18 arranged on the bottom 5 of cistern 4.
  • the lower end parts of legs 17 are enclosed by a sleeve 19 manufactured from a bearing material, the purpose of which will be elucidated hereinbelow.
  • the lever 15 is connected to a pull wire or chain 20 which has a plurality of steps 21 arranged with interspacing. Clamped between two adjacent steps 21 of pull wire 20 is a lip 22 which is fixed to the top edge of an overflow tube 23.
  • the overflow tube 23 has the purpose of preventing the level of the water 25 in cistern 4 reaching the upper edge of cistern 4 in the unforeseen case that a valve in the water supply were not to function properly. Should this be the case, the water 25 will rise in the cistern to the upper edge of overflow tube 23, whereafter the water will flow over this edge into the tube 23 and will flow therefrom into the discharge tube leading to the toilet bowl.
  • overflow tube 23 is provided with a connecting piece 28 with internal screw thread into which is screwed a lower tube 29 which has on its underside a double flange 24 in which the actual annular valve 2 is arranged.
  • the overflow tube 23 is further provided with an outer screw thread 26 onto which is screwed an O-ring 27 which fixes the main float 8, which will want to move to the surface of the water as a result of the upward force exerted thereon by the water 25.
  • the auxiliary float 9 is received in a holder 31 which is fixed onto the base 18 and is provided with two openings 32 through which protrude the bearing sleeves 19 of the legs 17.
  • the holder 31 has a central opening 40 through which is placed the lower tube 29 bearing the valve 2.
  • two float bodies 33 which together form the auxiliary float 9 and which each carry a snap connecting element 36 and which are displaceable in holder 31 along guide arms 41 of a guide block 35.
  • the guide arms 41 run at an incline relative to the direction of displacement of valve 2, whereby the snap connecting elements 36 can be placed in and out of engagement with an annular rib 37 arranged on lower tube 29 and an annular groove 38 recessed into lower tube 29.
  • Both float bodies 33 are substantially semi-cylindrical in shape and open on their underside (fig. 7).
  • the float bodies 33 each have a semi-cylindrical recess 48 with which they close round the central standing edge 40 of holder 31 and the lower tube 29 protruding therethrough.
  • the snap connecting elements 36 are arranged on the side of the recesses 48 facing toward the tube 29.
  • the holder 31 has an inner diameter 43 which is slightly larger than the external dimensions of the float bodies 33, so that they are movable to and from the lower tube 29 in the interior 43 of the holder.
  • the float bodies 33 further have guide grooves 42 on either side which co-act with the guide arms 41 of guide block 35.
  • Both guide arms 41 and guide grooves 42 are embodied at an incline relative to the longitudinal axis of the overflow tube 23 and lower tube 29 which determine the direction of displacement of valve 2.
  • the guide block 35 is formed by a bridge piece 46 which has on its outer ends protruding parts 44 which are received in openings 45 in the wall of holder 31.
  • the bridge piece 46 further has a central aperture 49 through which the lower tube 29 protrudes.
  • Fixed onto bridge piece 46 are caps 47 which carry the actual guide arms 41.
  • auxiliary float 9 When the auxiliary float 9 is under water a determined quantity of air will always be confined in the float bodies 33, whereby they will be subjected to an upward force.
  • the float bodies 33 will hereby move upward, in as far as this is allowed by guide block 35.
  • the float bodies 33 will herein be urged towards each other and towards lower tube 29 as a result of the sloping position of guide arms 41 and guide grooves 42.
  • the snap connecting elements 36 always lie against the wall of lower tube 29 under a bias produced by the upward force.
  • the push button 11 is depressed from the position shown in fig. 1 past the position shown in fig. 2 to the position shown in fig. 3.
  • the push button half 11A is herein depressed further than the half 11B, whereby the plunger rod 13 is displaced further than in the preceding case and the overflow tube 23 with lower tube 29 and a valve 2 connected thereto are also carried further upward.
  • the discharge opening 3 is now left clear again, whereby water 25 will flow from cistern 4 to the toilet bowl.
  • the float bodies 33 will, when the peripheral rib 37 of the lower tube 29 reaches the snap connecting elements 36, be pushed apart counter to the bias exerted by the upward force on float bodies 33, whereby rib 37 is pulled past the snap connection means 36.
  • the snap connecting elements 36 will then fall into the peripheral groove 38 of lower tube 29.
  • a flushing device is thus obtained with which the cistern 4 can be wholly or partly emptied as the user desires, depending on the waste in the toilet bowl.
  • the flushing water volume can be adjusted by moving the main float 8 along the screw thread 26 of overflow tube 23.
  • a delay in closing can be obtained such that in a full flushing the entire cistern 4 is really emptied.
  • the above described flushing device can otherwise also be used in combination with a flush interruption device, for instance of the type as described in applicant's earlier Netherlands patent application 9100986.
  • a flush interruption device for instance of the type as described in applicant's earlier Netherlands patent application 9100986.
  • FIG. 8 An alternative embodiment of a flush interruption device is shown in figure 8.
  • the push button 52 is formed integrally in this case. Flush interruption takes place by depressing the button 52 twice.
  • the valve (not shown) is closed. Depressing of the button 52 results in a tongue 54 of a bell-shaped member 57 which is pivotally suspended on a pressure pin 56 by means of a shaft 55 engaging in a recess 58 in lever 53. Due to the engagement the lever 53 tilts to the second rest position (Fig. 8C), wherein the valve is opened.
  • Fig. 9 shows in perspective a number of structural details which enable optimum functioning of the mechanism outlined above. It shows the bell-shaped member 57 which is provided on its underside with a tongue 54 interrupted by a recess 65. The tongue parts engage in cup-shaped recesses 58 in the lever 53. The cup-shaped recesses 58 are mutually separated by a rib 66 which prevents the bell-shaped member 57 becoming jammed with its two flanges 60' and 60" between respectively the edge 67 of the pressure pin housing 68 (Fig. 8E) and the recess 58 during the tilting to its first rest position.
  • the fin further has local thickened portions 69 which bound the tilting of the bell-shaped member.
  • Both chamfered sides 70 of the bell-shaped member 57 co-act with butting faces in the pressure pin housing 68 (not shown).
  • the bell-shaped member further has two flat stop sides 71. Both steps ensure that in the rest position the bell-shaped member 57 is always positioned at right angles to and straight under the pressure pin 56.
