Preparation for controlling the flushing valve of the flushing cistern

The present invention relates to a device for controlling the flushing valve of a toilet flushing kettle, and in particular to a control device for a flushing valve, which allows both full and partial emptying of the kettle to reduce water consumption.

Various arrangements for controlling the discharge valve are known, which also allow partial emptying of the kettle and in which the closing body of the valve is generally connected to the float to delay the closing of the valve to completely empty the kettle. In the known type of valve control device, the shut-off body is actuated by a pressure lever, which must be pressed a second time to completely drain to stop water leakage. Any reduction in water consumption depends entirely on the correct use of the device by the user and is therefore unreliable.

The second known type of valve feeder is normally equipped with two different floats: the first is defined by a normal overflow pipe and is used for full discharge and the second for partial discharge control. In a known preparation, the second float is generally held by the hook and must be released to prevent the first float from returning early.

The disadvantage of this type of control device is that the pipe must be equipped with a valve to overflow the pipe and to increase the price of the pipe. In addition, the retaining hook is complex and sensitive to operation.

It is an object of the present invention to provide a device for controlling a toilet flushing cistern of a flushing cistern, which is extremely simple and reliable and takes care to eliminate the aforementioned disadvantages, which are typically associated with known control devices.

According to the present invention, there is provided a device for controlling the toilet flush valve of a flushing cistern, comprising a closure body which is movable from the closed position in which the valve closes to the open position in which the valve opens, and a float for holding the return of said closure body. to the said closed position. It is characterized in that said float is integral with said closure body and is located in a container of small volume water; the first means is intended to initiate said container slowly to allow complete emptying of said kettle; and another means is intended to empty said container rapidly to cause partial emptying of said kettle.

According to a further feature of the invention, the second means comprises a container opening and a flap for closing said opening; the manual control is provided to control said flap so as to reduce the opening time of said valve. In the first embodiment according to the invention, the flap normally retains the opening of the container closed and the control body actuates the flap and the closing body simultaneously to cause partial emptying of the kettle. Conversely, according to a further variant of the invention, the flap normally holds the container opening open and the control body only triggers the shut-off valve of the discharge valve to cause the kettle to partially empty.

Embodiments of the preferred embodiment of the invention will be described by way of example, with reference to the accompanying drawings showing Figure 1 a side view, partly in cross-section along the center vertical plane of the flushing kettle emptying device according to the present invention; Figure 2 is a perspective view of the detail of the device of Figure 1;

Figure 8 is a partial cross-sectional view of the embodiment of Figure 1.

Mark 5 in Fig. 1 schematically shows a toilet flushing kettle comprising, as a conventional faucet - not shown - for connection to a water pipe and a float - not shown - for controlling the faucet. The kettle 5 also comprises a wall 6 of the bottom having a hole 7 into which a discharge control apparatus, which is denoted as a whole by 8, is adapted, and whose component parts are generally made of rigid plastic material.

Apparatus 8 comprises a connection piece 8 for a drainage pipe having a cylindrical outer threaded end 11 inserted into a hole 7 in the wall 6. The connection piece 9 for a drainage pipe also comprises a ring 12 that is integral with the bottom part 11 and fixed to wall 6 by means of a ring nut - not shown - and via an intermediate seal. The drainage pipe connection piece 9 also comprises a top portion 13 which is connected to a ring 12 by four radial sections 14 defining four large openings 16 (Figure 5) that allow water to flow from the boiler 5 into the compartment 11.

Apparatus 8 also comprises a tubular receptacle, which is denoted as a whole by 17 and comprises a compartment 18 of the bottom defined by a cylindrical side wall 19 having an arched shaped recess 20. The wall 19 comprises two radial studs 21 (only shown in FIG. 5). one) by which the container 17 is fixed in a bayonet manner to two annexes 22 with a slot at the top of the compartment 13 of the connection piece 9; and two sections 23 of the annular rib on which the upper edge of compartment 13 rests.

The container 17 also comprises an upper compartment 24 defined by a side wall 26 and closed at the top by a removable cover 27 comprising a top wall 28 and a side wall 29 having two slots 31 in which two adjacent wedge-shaped attachments attach. 32 (Figure 6) on the side wall 26.

The side walls 19 and 26 of the compartments 18 and 24 are connected by an annular step 33 which extends at a recess 20. The lateral wall 19 of the bottom region 18 is closed at the bottom by a wall 34 of the bottom having a central opening 36 defined by a ring 37 a predetermined diameter; and the top wall 28 of the lid 27 has a second center opening 38 defined by a similar ring 39 and of the same diameter as the opening 36.

The control device 8 also comprises a conventional overflow tube 41, which in turn comprises an upper funnel portion 40 and a cylindrical compartment 42 of the bottom of the same diameter as the rings 37 and 39, which therefore slides inside and is guided by the rings 37 and 39 with minimum clearance.

The control device 8 also comprises a first control means for slow emptying of the container 17, comprising a compartment 43 of a section 42 of the overflow pipe 41, which is located below the bottom wall 34 and is slightly smaller than the compartment 42 in diameter.

The compartment 43 ensures that water can flow between the container 17 and the kettle 5 in the slit between the ring 37 and the compartment 43 as the tube 41 rises to discharge water.

At the lower end, section 42 of the pipe 41 comprises a second section 44 of small diameter forming a step 46 and connected to the shut-off body 47 of the discharge valve and as a whole designated by 48 and defined by the body 47 and the shoulder 49 of the ring 12.

In more detail, the closure body 47 is defined by a ring made of an elastomeric material, preferably rubber, and positioned between two flanges 51 and 52. The flange 51 is integral with a sleeve 53 in which a portion 44 of the pipe 41 is inserted so that the step 46 gripping the edge of socket 53; and the flange 52 is integral with the sleeve 54 having a hook edge 56 to receive inside the step 46. The sleeve 54 also comprises at least two axial slots 57 that allow a certain degree of flexibility of the hook edge 56.

When the sleeve 53 and the rubber ring 47 are rotated outward relative to the compartment 44, the sleeve 54 is inserted into the compartment 44 so that the hook edge 56 is caught in the step 46. The ring 47 is movable together with the hose 41 from the position in Fig. 1 as it closes valve 48, to the open position which opens valve 48 and is shown by the dashed line in Figure 1. The end at the bottom of the overflow pipe 41 therefore has no closure device or valve so that the hose 41 does not perform float function and the overflow function is never restricted.

The overflow pipe 41 is integral with the float 58 located in the upper portion 24 of the container

17. In more detail, float 58 comprises a compartment 59 formed by a cylindrical compartment (Fig. 7) defining an angular slot 60 and comprising an outer wall 61 which slides along the side wall 26 of compartment 24 of the container 17. Float 58 also comprises an inner the socket 62, which is longer than the wall 61, and the casing 41.

The float 58 also comprises an intermediate wall 63 between the wall 61 and the socket 62 and the same length as the socket 62. The walls 61 and 63 extend into two L-shaped radial walls 64 and are connected to the radial walls 65; and further radial walls 66 are provided between wall 63 and sleeve 62.

Finally, the float 58 also comprises a C-shaped upper wall 67 connecting the sleeve 62 to the walls 61 and 63, such that the float 58 also captures the volume of air trapped between the upper wall 67, the radial walls 64, the sleeve 62 and the inner wall 63 and between the upper wall 67, the radial walls 64, the outer wall 61 and the intermediate wall 63.

The float 58 is connected to the overflow tube 41 in an axially adjustable manner. In more detail, the inner surface of the socket 62 has an axial filler piece 68 (FIG. 7) which acts frictionly on the outer surface of the pipe 41; and the sleeve 62 has an axial groove 69 that lies diametrically opposite the filler piece 68 and into which a rib 70 (Fig. 1) extends radially from the tube 41 to prevent the float 58 from rotating relative to the tube 41.

The control device 8 also comprises a second control means comprising an opening 71 (FIG. 4) formed in the step 33 of the container 17 at an arc-shaped recess 20 in the wall 19 and normally closed by an associated flap 72 which is actuated to rapidly empties container 17. Pipe 41 is positioned in such an angular position that two radial walls 68 of float 58 are mounted on opposite sides of opening 71. The flap 72 is essentially an inverted sponge with essentially a ball head and is guided by two studs supported by a step. 33.

The flap 72 is fixed in a known manner to the end of a substantially vertical bar 75 having a shoulder 76 which is supported by an annular step 77 having an inclined opposite surface 78. The arm 76 is held by a retaining body defined by the transverse body 79 of the frame 81. which has two arms 82 (FIG. 3) attached to a horizontal shaft 83 rotating on two attachments 84 at the top of the wall 28 of the cover 27.

The arms 82 comprise the corresponding attachments 86 extending substantially horizontally to each side of the tube 41. The two attachments 86 are held by a stepped means attached to the tube 41 and defined by two radial wings 87 (Fig. 2) integral with tube 41 and so arranged as to lower attachments 86 to follow the predetermined upward path of tube 41.

The opposite levers 88 and 89 collide on the base 90, which is integral with the container 17. The lever 89 is movably attached to the upper end of the bar 75, while the lever 88 is movably attached to the connecting member 91, which is connected to the slot and plug by the attachment. 92 (Fig. 2) of part 40 of pipe 41, such that connecting member 91 pulls pipe 41 upward after a certain idle.

The control device 8 also comprises manual actuators for selectively actuating the pipes 41 and the flaps 71 (Figures 1 and 5). In more detail, the manual actuator comprises two controls or pushers 93, 94 that coaxially and vertically slide on the support 90, and selectively actuates the levers 88 and 89. The pushers 93 and 94 are connected by two corresponding push buttons (no shown), which are located in a connection piece connected to the upper wall of the kettle 5, for example, as described in European patent application No. 97105696, filed by the present applicant.

The inner thrust body 93 only triggers the lever 88 to cause complete emptying of the kettle 5, while the outer thrust body 94 only triggers the two levers 88 and 89 to cause partial emptying of the kettle 5. Support 90 is supported by a U-shaped inverted structure 95 comprising two gears 96, each of which is removably supported by a bolt 97 carried by the corresponding cap attachment 98 27.

The gears 96 and the articulated connection of the levers 88 and 89 with the connecting member 91 and the bar 75 ensure the adjustment of the position of the structure 95 to the distance between the upper wall of the kettle 5 and the lower wall 6, as described in the aforementioned European patent application.

The discharge control apparatus described above operates as follows.

At rest, the kettle 5 is filled with water up to level H, which is defined by a conventional float that closes the power tap; the overflow tube 41 is shown in the reduced position in Figure 1, in which the annular tube 47 rests on the shoulder 49 to close the discharge valve 48; and the container 17 is therefore water-free, with a compartment 43 of the compartment 42 of the pipe 41 positioned below the ring 37.

The wings 87 (Figures 2 and 3) of the section 42 of the pipe 41 therefore hold the frame 81 in position in Figure 1 with the transverse body 79 separated from the annular step 77. If the feed tap is not closed, the water level rises steadily to and through the upper edge of the section 40 pipes 41 and the water is emptied directly through the socket 54 and the compartment 11 of the connection piece 9.

When released, the internal thrust body 93 rotates the lever 88 clockwise by lifting the connecting member 91 which, after a certain dead stroke, lifts the tube 41 together with the float 58 so that the rubber ring 47 is separated from the shoulder 49 to open the valve 48, and the water in the kettle 5 flows through the openings 16 and the compartment 11 of the connection piece 9.

As it moves up, the tube 41 brings the small diameter compartment 43 to the ring 37 of the wall 34 at the bottom of the container 17 so that the water in the kettle 5 flows into the container 17 until it reaches the same level as the water level in the kettle 5. Hydrostatic pressure water at the float at this point prevents the pipe 41 from moving downwards; and the wings 87 of the compartment 42 of the pipe 41 momentarily lower the attachments 86 of the lever 2 so that the transverse body 79 of the frame 81 is rotated, but without consequence, by its own weight by resting on the bar 75.

When the water from the kettle 5 is emptied, the water level in the kettle drops. However, the water level in the container 17 drops more slowly so that the hose 41 and the rubber ring 47 fall slowly along with the float 58 to ensure that the kettle 5 is completely emptied. As the tube 41 approaches the position when the bottom is closed, the wings 87 grasp attachments 86 again to return the frame 81 to the rest position; ring 47 now closes valve 48 so that the kettle 5 begins to fill; and the tube section 41 prevents water from flowing into the container 17 so that the float 58 remains in the lower position even when the water level in the kettle 5 rises.

In contrast, when released, the outer thrust body 94 rotates the lever 88 as before, so that the tube 41 rises and the wings 87 lower the attachments 86 so that the frame 81 rotates clockwise, and on the other hand, the lever 89 also rotates. which pulls up the pole 57 together with the flap 72 so that the annular step 77 of the pole 75 rises above the transverse body 79 which is trapped under the shoulder 76 to hold the pole 7 in a raised position.

The hatch 72 thus opens the opening 71 so that water in the kettle 5 quickly fills the container 17. When the amount of water corresponds to half of the discharge, it empties from the kettle 5 and the water in the kettle 5 and the container 17 drops to a level h slightly below the level of the opening 71 , so container 17 is quickly emptied.

In this case, the float 58 quickly returns to the standstill together with the hose 41, thus closing both valves 48 and the gap between the hose compartment 43 and the ring 37; the wings 87 of the compartment 42 of the tubes 41 are primed by annex 86 of the arms 82, thus rotating the frame 81 anticlockwise; the transverse body 79 of the frame 81 discharges the step 77 of the rod 75, which moves back down under its own weight, so that the flap 72 closes again the opening 71 and the water begins to flow into the kettle 5 to return to the H level.

Figure 8 shows an embodiment of the invention in which the container 17 is normally open and is closed only when it causes the kettle to be completely emptied. In Fig. 8, the marked parts which use the same reference marks as in Fig. 1 are identical and act in exactly the same way as the corresponding works in Fig. 1 and are therefore not described below.

In the embodiment of FIG. 8, the step area 33 of the container 17, which is located between the walls 64 (FIGS. 6 and 7), has an opening 171 which receives a socket 170 of a predetermined height; the rod 175 is inserted inside the sleeve 170 and connected to the lower end by a tapered flap 172 to close the opening 171, but this is normally positioned such that the opening 171 is open; and the rod 175 is connected at the top to a lever 89, which rotates a U-shaped structure 95, which is actuated by an external pressure body 194 to cause the kettle 5 to be completely emptied.

-1010

The rod 175 also has an axial rib 177 facing the tube 41 and having a lower arm 176 caught by the transverse body 179 of the frame 81, which is identical to the frame 81 of Figure 1. The lever 88 is connected to the connecting member 91 and is controlled with an external thrust body 194 to cause complete emptying, and with an internal thrust body 193 to cause partial emptying of the kettle 5.

The variant of Figure 8 operates as follows.

When released, the outer thrust member 194, on the one hand, rotates the lever 88 clockwise by lifting the connecting member 91, which, after a certain dead stroke, lifts the tube 41 together with the float 58 so that the rubber ring 47 is released from the shoulder 49, to open the valve 48, and the water in the kettle 5 flows through the openings 16 and the compartment 11 of the connection piece 9.

The outer thrust body 194 also rotates the lever 189 to position the shoulder 176 of the rib 177 of the bar 175 over the transverse body 179 and to move the flap 172 to a closed position, which closes the opening 171 in the container 17. When the tube 41 moves to a raised position, the wings 87 (Fig. 2) lower the annexes 86 so that the frame 81 rotates clockwise; the transverse body 179 of the shoulder 176 to lock the bar 175 in the raised position and keep the opening 171 closed; the small diameter section 43 of the tube 41 moves upwards to the ring 37 of the floor wall 34 of the container 17 so that water in the kettle 5 begins to slowly flow into the container 17 to cause complete emptying of the kettle 5, as in the case of triggering the internal thrust body 93 in Figure 1 .

Conversely, when lowered, the internal thrust body 193 merely rotates the lever 88 as before and leaves the flap 172 in the open position so that the tube 41 moves to a raised position; frame 81 can now rotate clockwise but cannot grasp the shoulder 176 due to the bar 175 being lowered; and pipe 41 opens valve 48 to begin draining water from the kettle 5.

-1111

The water in the kettle 5 quickly fills the container 17 and when the amount of water corresponding to half of the discharge is drained, it drops to a level h slightly below the level of the opening 171, so that the container 17 empties quickly, the float 58 quickly returns to a standstill and the water again flows into kettle 5 to restore H level.

The advantages of the device for controlling the discharge valve of the present invention in relation to known devices will be clear from the foregoing description. In particular, tube 41 does not require a float to act as a float; float 58 has no retention hook; and the flap 72, 172 is temporarily retained by the body 79, 179, which is controlled by the tube 41 only, so that the device is cheaper to manufacture and operates more easily.

Of course, modifications to the control device as described herein may be made without departing from the scope of the accompanying claims. Floater 58, for example, may be shaped differently from what has been described; the opening 71, 171 may be formed in the wall 34 of the bottom of the container 17; and step 33 may be omitted.
