Definitions

  • the present invention relates to a device for controlling the discharge valve of a lavatory flush tank.
  • the invention relates to a discharge valve control device enabling the tank to be emptied completely or partially, for the purpose of reducing water consumption.
  • Document EP-A-426 224 describes a control device of the above type, wherein the discharge valve shutter is connected to a float to delay closing of the valve and so empty the tank completely; a rocker arm is connected to the shutter, and carries the pivots of two elements connected by a slot and pin to an oscillating plate; the oscillating plate may be set by the two elements to either of two positions, each for predisposing a respective element for operation; and the two elements are activated alternatively by a single button, first to open and then to close the discharge valve at any time, regardless of the action of the float.
  • the above device has several drawbacks.
  • the connection between the hinged elements and the oscillating plate is fairly complicated to produce and assemble; and the rigid connection of the device to the ceramic material of the tank makes it difficult to adjust and adapt the device to different tank sizes.
  • a device for controlling the discharge valve of a lavatory flush tank comprising a shutter for opening and closing said valve; a manual control member for activating said shutter; a float connected to said shutter and for delaying closure of said valve to fully discharge the tank; a rocker arm connected to said shutter; and a pair of elements hinged to said rocker arm and activated alternatively by said control member to so control said shutter as to open said valve and close the valve following partial discharge of the tank; and characterized in that said elements are pushed elastically into a position of engagement by said control member.
  • number 5 indicates as a whole a lavatory flush tank, which is preferably made of ceramic and, as usual, comprises a tap (not shown) for connection to the water supply pipe, and a float (not shown) for controlling the tap.
  • Tank 5 comprises a bottom wall 6 having a hole 7 in which is fitted a device for controlling discharge of the water and indicated as a whole by 8.
  • the components of device 8 are generally made of rigid plastic material, in the following description, the material of the components is only specified when other than plastic.
  • Device 8 comprises a discharge fitting 9 having a bottom portion 11, which defines the discharge valve and is threaded externally.
  • Fitting 9 also comprises a flat shoulder 12, and a top portion 13 having openings 14 for the passage of water to valve 11, which is inserted inside hole 7 in bottom wall 6 via the interposition of a seal 16, and is fixed to wall 6 by a threaded ring nut 17.
  • Device 8 also comprises an overflow pipe 18, which slides vertically inside a cylindrical casing 19; the bottom end of pipe 18 is provided with a shutter defined by an elastic ring 21, which cooperates with shoulder 12 to open and close discharge valve 11; and pipe 18 is fitted with a float 22 to delay closure of valve 11 and so fully discharge tank 5.
  • Casing 19 is fitted with an upside down U-shaped structure 23 ( Figures 2-4) defined by two parallel arms 24 connected by a crosspiece 26.
  • the two arms 24 are each provided with a vertical outer reinforcing rib 25, and may be so fitted to casing 19 ( Figure 1) as to be axially adjustable in any known manner.
  • Crosspiece 26 ( Figures 2-4) is in the form of a bottomless paralleleiped box, and comprises two transverse walls 27, each having a horizontal slot 28 at the bottom. Walls 27 and two walls 29, perpendicular to walls 27, terminate at the top in shoulders 30.
  • the compartment defined by walls 27 and 29 houses assembly means comprising a sleeve 31, the inner surface of which has a helical rib 32.
  • the outer surface of sleeve 31, comprises two shoes 33 sliding along walls 27 of crosspiece 26.
  • Each shoe 33 is guided at the top by shoulder 30 of the corresponding wall 27, and comprises a bottom tongue 34, which, at assembly, is forced inside slot 28 of corresponding wall 27.
  • Sleeve 31 is therefore permitted to slide along, but not to rotate inside, crosspiece 26.
  • Control device 8 also comprises a single control button 36 housed inside a cup-shaped support 37.
  • a compression spring 39 for normally keeping button 36 in the top position, is fitted between button 36 and an annular wall 38 of support 37; wall 38 is fitted with a sleeve 41, the outer surface of which has a thread which screws onto helical rib 32 of sleeve 31; and support 37 has a shoulder 42 for housing a spacer ring 43 ( Figure 1).
  • Cup-shaped support 37 is fitted to the usual cover 44, also made of ceramic, of tank 5; for which purpose, cover 44 comprises a hole 46 of a diameter corresponding to that of sleeve 41.
  • cover 44 comprises a hole 46 of a diameter corresponding to that of sleeve 41.
  • the diameter of hole 46 is larger than in Figure 2; and the support is inserted inside the hole so as to rest on cover 44 with no spacer required.
  • Control device 8 also comprises a rocker arm defined by a substantially rectangular frame 47.
  • Frame 47 comprises two opposite sides 48 having, at the respective mid points, two seats for two pins 49 integral with corresponding arms 24 of structure 23.
  • Frame 47 also comprises a further two sides 51, one of which comprises an appendix 52 connected by a tie 53 ( Figure 1) to a crosspiece 54 inserted inside two diametrically-opposite openings in overflow pipe 18.
  • Tie 53 is such as to enable the connection to crosspiece 54 to be adjusted in any known manner, to adapt the device to various types of tank 5.
  • each element 56, 57 is defined by a pair of arms 58 and 59 ( Figure 3) connected by an L-section crospiece 61; and sides 48 ( Figure 2) of frame 47 each have two pins 62 and 63 about which arms 58 and 59 of elements 56 and 57 pivot.
  • Arm 58 of each element 56, 57 has a cylindrical pin 64, which is arrested against a corresponding vertical inner rib 66 along the center line of the corresponding arm 24 of structure 23.
  • Arm 59 of each element 56, 57 has an oblong appendix 67, which is also arrested against a corresponding rib 66, but extending in the opposite direction to rib 66. Pin 64 and appendix 67 therefore define a counterstop cooperating with ribs 66, which define a relative stop member.
  • Frame 47 also supports two leaf springs, each defined by a tongue 68, 69 of elastic plastic material.
  • Each tongue 68, 69 has one end fixed to a respective pin of a respective pair 62, 63 on the same side 48 of frame 47.
  • the other end of tongue 68 acts on pin 64 of element 56, while the other end of tongue 69 acts on appendix 67 of element 57.
  • the pair of pins 62 of element 56 is located further away than the pair of pins 63 from the pivot of frame 47 defined by the axes of respective pins 49, so that control member 55 must travel further to activate frame 47 by means of element 56 than by means of element 57, thus defining a tactile distinction between the two activations.
  • Tongues 68 and 69 push elements 56 and 57 towards ribs 66 so as to keep element 56 or 57 (element 56 in Figure 1) resting against ribs 66 by means of respective pin 64 and respective appendix 67.
  • tongue 68 is deformed to a lesser degree than tongue 69, thus defining a further tactile distinction between the two activations.
  • Member 55 controlling elements 56 and 57 is fittable adjustably to button 36, and comprises an upside down truncated-cone-shaped engaging portion having an ample surface by which to act on each crosspiece 61 and for preventing crosspiece 61 from impeding or interfering with the upward return movement of button 36.
  • control member 55 is defined by a cylindrical bar 74, which is forced inside an axial hole of a sleeve 75 integral with button 36; bar 74 has a hollow cylindrical head 76 for engaging crosspieces 61; head 76 is connected to bar 74 by an upside down truncated-cone-shaped portion 77; and bar 74 may be cut to the required length at assembly.
  • control member 55 is defined by a threaded bar 71, which is screwed inside a threaded sleeve 72 integral with button 36; bar 71 has an upside down truncated-cone-shaped head 73 for engaging crosspieces 61; and, at assembly, bar 71 is screwed into the best position to act on crosspieces 61.
  • Control device 8 operates as follows.
  • tank 5 At rest (Figure 1), tank 5 is filled with water to the level defined by the float closing the supply tap; and frame 47 is positioned as shown in Figure 1, with element 56 in the top position and element 57 in the bottom position. More specifically, tongue 68 holds pin 64 and appendix 67 of element 56 against ribs 66, so that respective crosspiece 61 is engaged by control member 55; whereas tongue 69 is relaxed so that appendix 67 of element 57 is released and pin 64 and appendix 67 detached from ribs 66.
  • control member 55 acts on crosspiece 61 of element 56, which rotates frame 47 clockwise into the position shown by the dash line in Figure 2; frame 47, by means of tie 53 ( Figure 1), raises pipe 18 together with ring 21 to open discharge valve 11; and frame 47 also raises element 57, which is now pushed by tongue 69 to rest on ribs 66, while tongue 68 allows element 56 to rotate clockwise.
  • Button 36 may now be released, and is restored to the top position by spring 39.
  • spring 39 overcomes the action of tongue 69, so that crosspiece 61 of element 57 allows button 36 to return to the top position together with portion 73, 77.
  • Pipe 18, on the other hand, is kept in the raised position by the hydrostatic thrust acting on float 22 until tank 5 is emptied completely. As long as pipe 18 is raised, frame 47 is also kept in the rotated position, so that crosspiece 61 of element 57 is engaged by control member 55.
  • control member 55 acts on crosspiece 61 of element 57 to rotate frame 47 positively anticlockwise; frame 47, by means of tie 53, lowers pipe 18 to close discharge valve 11; and frame 47 raises element 56 and lowers element 57 to restore the control device to the Figure 1 position.
  • frame 47 and the two hinged elements 56 and 57 are easy to produce and assemble, and provide for a high degree of reliability; the adjustable connection of various components of the device provides for adapting the device to different tanks; and the truncated-cone-shaped portion 73, 77 of control member 55 prevents any interference between the return travel of the control member to the rest position and positioning of hinged element 56, 57 for subsequent operation.
  • tie 53 connecting frame 47 to pipe 18 may be hinged to an appendix integral with pipe 18; ribs 66 may be replaced by appropriate cam profiles; and tongues 68 and 69 may be replaced by one spring stretched between the two elements 56 and 57.
