Definitions

  • the invention consists of some improvements in flushers of toilet tanks used for those flushers in which it is possible to select at will the volume of water, although the improvements are also applicable to other flushers, since one of the advantages lies on the adaptability and universality of the design of the basic parts of the flusher, which in practice results in the elimination of large stocks upon making it possible to use common parts in different models of flushers.
  • the invention proposes a new and effective system that ensures the immobilization of the overflow tube, be it during partial flushing or during total flushing.
  • the invention also deals with the correct vertical guiding of the overflow tube, as well as of some parts of the operating device of the flusher.
  • Two floats located in a diametrically opposite position and provided with means to retain the overflow tube at a certain moment, due to the floating of both of them, carry out their work in this cavity.
  • registrations include a third float assembled on the overflow tube and with the possibility of adjusting the height thereof, which determines the volume of water of the partial flushing.
  • the overflow tube moves upward less than during the pushing for total flushing, in such a way that this overflow tube is not blocked by the action of the wedges of the bottom floats that remain floating.
  • this overflow tube will drop closing the opening, until the water level drops below the location of the two bottom floats and the reversed hood is emptied in the necessary amount, at which moment, the wedges will release the overflow tube, dropping and obtaining total flushing.
  • the invention proposes some improvements in flushers of toilet tanks that are characterized by the features according to claim 1. They comprise a new base hood structure that will allow us to have the different parts that will later comprise the flusher in its different versions.
  • the base hood is characterized in that it includes anchoring means of the parts that form the body of the flusher.
  • the base hood is characterized in that it includes some grooves that make it possible to divert part of the liquid of the flushing towards the top surface of the sealing joint during partial flushing. This diversion of the liquid will exert pressure on the top surface of the joint enabling a rapid drop thereof as soon as the pre-established volume has been emptied.
  • the hood is also characterized in that it includes individual anchoring shafts of some bottom floats that jointedly couple to these shafts, in such a way that this individuality results in a better and gentler operation, and a less complicated assembly.
  • these shafts include float centering means.
  • these bottom floats will be able to be assembled on another pair of shafts identical to the preceding ones and also located on the neck of the base hood, a bit further up for the purpose of raising the location of the floats, getting them to actuate before and therefore, empty less water when totally flushing the toilet tank.
  • the overflow tube will have an additional anchoring groove in order to interact with the floats in this new position.
  • the base hood Another characteristic of the base hood is that its neck, aside from acting as a bottom guide of the overflow tube, includes some openings or windows that permit some projecting wedges of the bottom jointed floats to operate in order to retain the overflow tube while the flushing takes place.
  • At least one outlet is included.
  • This hole empties the type of glass that forms the base hood when the different complementary parts that form the flusher are assembled on it.
  • the discharge of the water can be regulated by using a simple movable sealing joint, comprised of a rotating ring that is assembled on the outside of the hood.
  • this bridge includes anchoring means where other top adjustable floats responsible for keeping the overflow tube at the designed height are located. This adjustment is done in terms of the volume that is desired or needed to drain when a double flushing system is used.
  • anchoring means are aligned vertically with the anchorings of the bottom floats in order to permit the use of similar or identical parts.
  • the improvements of the invention permit us to use a single type of float, in such a way that the two pairs of floats will be identical, and besides, unlike already known patents the top adjustable floats are not assembled on the overflow tube, but rather as we have seen they are jointedly anchored to the support bridge, in such a way that they are independent from the movements of said overflow tube. This circumstance makes its lighter, as it does not depend on extra weight that hampers the movements thereof.
  • the support bridge includes some stops in order to limit the tilting of said floats.
  • Said top floats will optionally be assembled on a complementary support part, in which case this complementary part is the one that is anchored at the desired height on the support and the floats are perfectly operative.
  • the flusher operating device can be comprised in principle by a classic wedge system that actuates a lever, such as in patent of invention no. 9701529 for example.
  • the operating device includes different new aspects that will be explained in detail hereinafter.
  • a duct that houses, a wedge that actuates the lever, as an angular part responsible for transmitting movement from the push mechanisms.
  • Another characteristic of the operating device of the flusher is that the jointing shaft of the lever is moved away from the center of the flusher, in a point closer to the actuation area of the wedge. In this way we gain a gentler operation, which the small slant towards the center that said wedge has when it actuates on the lever contributes to.
  • the above-cited angular part includes a recess in order not to limit the rise of the overflow tube, as well as some ribs to reduce the friction with the inside walls of the duct where the angular part is guided along one of its branches.
  • this duct acts as a top outside guide also of the overflow tube in its vertical movement.
  • the operation is similar to that of conventional flushers with the difference that a top float, assembled on the overflow tube, is not used, but rather two symmetric floats assembled on independent shafts identical to the bottom ones and whose purpose is to block the overflow tube at the desired height, in terms of the volume of water that is desired to be flushed.
  • the floats press with the projections or stubs on the surface of the overflow tube, since they tend towards being horizontal due to their floating.
  • the base hood also permits double flush flushers to be formed, but also complete flushing flushers, by the pull mechanism as well as by the push mechanism.
  • This hood will then have some radial stubs as means for assembling a bridge with a pull system with an eccentric. So that the pull mechanism is extendible in height an over-hood that will act as the reversed glass will be assembled on said base hood and by the over-hood the height adjustable overflow tube will move, that will be guided at the top by said over-hood.
  • the part to be assembled on the base hood will always act as a support of the parts that complement the flusher and in turn the reversed glass; as we have commented above.
  • the main double flush model may be manufactured with a single bottom float, using for the locking or blocking of the overflow tube some movable wedges that, when said float floats, touch the overflow tube managing to block it when the ring-shaped recess is located at the height of the ends in a total flushing phase.
  • a base hood (1) that has a structure prepared for placing upon it the different parts, which will later constitute the flusher in its different versions and embodiments.
  • the base hood (1) has in principle some radial stubs (2) used as anchoring means of the parts that form the body of the flusher.
  • the base hood (1) also includes some narrow grooves (5) additional to the conventional emptying openings (6), grooves (5) that serve to divert part of the liquid after the discharge to the upper surface of the sealing joint (7) which is also conventional, during partial flushing as it has already been commented on in the preceding sections, in such a way that in a partial flushing the sealing joint (7) takes on a lower position than during total flushing.
  • this small amount of water that passes through the grooves (5) of the base hood (1) will exert pressure on the top surface of said joint (7) enabling the rapid drop (sealing) thereof as soon as the pre-established volume of water has been emptied and the floats stop actuating.
  • the base hood (1) also includes individual anchoring shafts and jointing shafts (8) for the coupling of some bottom floats (9).
  • These shafts (8) include stops (10) to ensure the perfect centering of each float.
  • the base hood includes a guide neck (11) wherein the overflow tube (20) is conveyed and guided and this neck (11) includes some openings (12) that permit the actuation of some stubs or projections (13) on the overflow tube (20). This permits us to have longer guiding for the overflow tube (20).
  • the projections (13) form part of the bottom floats (9) and they fit in a ring-shaped recess (33) provided for in the overflow tube.
  • the base (16) could include at least a side hole (17) in order to empty the water from the inside of the reversed hood, in a similar way as the above-cited hole (14).
  • anchoring means defined by pairs of stubs (18) for the assembly of top floats (19) that are responsible for keeping the overflow tube (20) at the desired height, in terms of the volume that is desired to be flushed in the tank when a double flushing system is used.
  • top floats (19) will be assembled directly on a new support part (39), that will be the one that is anchored at the desired height of the support bridge (15').
  • said support part (30) will have pairs of stubs (18') similar in shape and function to the stubs (18).
  • the entire assembly will be located on the support bridge, but this time using some elastic projections (40) that will be introduced in some new holes (41) connected to each other by narrowings (42), in such a way that the position of said elastic projections may be varied, and therefore, the location of the floats without the need to remove them from the line that said holes (41) form.
  • the support part (39) includes some longitudinal protrusions (44) that will be introduced in the guiding grooves (45) of the support bridge (15'), in order to prevent the lateral movement of the assembly formed by the floats (19) and the cited support part (39).
  • One of the most important advantages of this invention is the possibility of using a single type of float, in other words, the four floats used in this flusher are identical, and besides, unlike the already known patents, the adjustable floats (19) are not assembled on the overflow tube (20), but rather as we have seen they are jointedly anchored on the support bridge (15), in such a way that they are independent from the movements of said overflow tube, which makes it lighter as no extra weights which hamper the movements thereof are depended on.
  • the support bridge includes some stops (21) in order to limit the tilting of the floats (19).
  • the operating device comprises a classical wedge system (patent of invention no. 9701529 ) that actuates on a lever (23), which also has certain new aspects, which are the following:
  • overflow tube (20) rises and drops in an absolute vertical manner in order to ensure correct operation.
  • Operation is similar to that of conventional flushers with the difference that a top float assembled on the overflow tube is not used, but rather two symmetric floats (19) assembled on independent shafts identical to the bottom ones and whose purpose is to block the overflow tube at the desired height, in terms of the volume of water that is to be flushed.
  • the volume of water to be emptied will logically be in terms of the position in which we have locked the floats (19).
  • the locking of the overflow tube is done by the bottom floats (9) in another ring-shaped recess (33). Later the latter is not released until the level of water in the tank has dropped below the floats and the reversed glass has been emptied.
  • the over-hood or semi-hood (4) will be assembled with the overflow tube (20') whose height can be adjusted, a semi-hood that includes at least a side opening (38) for emptying water.
  • This semi-hood (4) will have some radial stubs (34) in order to assemble a bridge (35) for a push system with an eccentric (36).
  • the base hood (1) makes it possible to form, not only double flush flushers, but also full flush flushers, by a pull mechanism as well as by a push mechanism.
  • the bottom floats (9) will be able to be mounted on another pair of shafts (8') ( Figures 9 , 10 ), just like the anterior ones (8) and also located on the neck (11) of the base hood (1) but somewhat higher, for the purpose of lifting the location of these floats (9), getting the floats to actuate before and therefore, less water is emptied as a total flushing of the tank is carried out.
  • the overflow tube (20) will have an additional anchoring groove (33) in order to interact with the floats in this new position.
  • the openings (12) will only be used in the event of placing the floats on the shafts located in the bottom part of the neck and not in this new location.
  • the main double flush flusher can be manufactured with a single bottom float (9'), using for the locking or blocking of the overflow tube (20) some movable wedges (37) that, when said float (9') floats, touch the overflow tube managing to block it when the recess (33) of the overflow tube is located at the height of the ends thereof in a total flushing phase.
  • said wedges (37) tilt, in other words, they open and stop touching the overflow tube in order to rest on the guiding neck (11), at which time the sealing and/or end of the total flushing of the tank would be produced.
