Description

Refinements in tank dischargers of toilets.

Object of the invention

The invention consists of improvements in toilet tank dischargers intended for those arresters in which it is possible to select at will the volume of water, although improvements are applicable also to other arresters, as one of the advantages lies in the adaptability and universality of the design of basic parts of the downloader, which in practice will result in removal of large stock by enabling the use of common parts in Different models of arresters.

They are applicable to both simple downloads and also to double download.

In all cases, the invention advocates a new and effective system that ensures the immobilization of the overflow, either during a partial discharge or during a total discharge

The invention also deals with the correct guidance  vertical overflow, as well as some parts of the actuator of the arrester.

Background of the invention

Currently, there are devices for discharge, such as the European invention patent number E-96200356 and utility model number 9701307.

Both refer to double downloaders download of the so-called inverted bell, as they support its operation in the action of some floats located in the inside of a cavity open at the top as a glass.

In that cavity two buoys or their work perform floats located in diametrically opposite position and equipped with means to retain the tube or overflow at a certain time, by the flotation action of both.

These records include a third mounted buoy  over the overflow tube and with the possibility of regulation in height, which determines the volume of discharge water partial.

The operation of these two arresters is the next.

First there are two push buttons that make raise the overflow to different heights.

When we press for partial download, the overflow moves up less than in the press of total discharge, so that this overflow is not blocked by the action of the wedges of the lower buoys that remain floating

When the water stops floating the buoy superior, there being no element that keeps it floating, it and the overflow tube fall and block the outlet.

If the (wider) push makes the wedges on a retention area of the overflow tube, it does not it will fall shutting the outlet, until the water level drops by below the location of the two lower buoys and empty it necessary, the inverted bell, at which time the wedges they will release the overflow tube, falling and obtaining a discharge total.

In both documents two types are used different from floats and the inverted bell where the inferior, it is solidary of the main body. In addition, in both referred records complicated mechanisms are used to discriminate the type of pulsations. This is because at arrange a buoy mounted directly on the overflow, they need to limit the movement of it, as it tends to float and It will always produce a total download.

This on the one hand forces to have more stock of pieces, and on the other, limits the use of the body or hood of the downloader or other parts, for exclusive use in this type of operation, when the market demands different types, One-touch download, with shooter, single downloads etc.

All this implies an extreme increase in this type of downloader, which makes it difficult to enter in the market despite the undeniable ecological advantages.

Description of the invention

To achieve the objectives and avoid drawbacks mentioned in the previous sections, the invention proposes improvements in downloaders of toilet tanks that are characterized in principle because they comprise a new base bell structure that will allow us arrange the different elements that will then constitute the downloader in its different versions.

The base bell is characterized in that it includes anchoring means of the pieces that form the body of the Downloader.

In turn, the base bell is characterized because incorporates slots that allow to derive part of the liquid from the discharge towards the top face of the seal during a partial discharge That derivation of the liquid will exert a pressure on the upper face of that joint favoring a rapid lowering it as soon as the volume has been evacuated prefixed.

The bell is also characterized because incorporates individual axes of anchorage of lower buoys that  they are articulated in these axes, so that this individuality results in better and smooth operation, and a less complicated assembly, also including such middle shafts of centered of the buoys.

Optionally these lower buoys may mounted on another pair of axes equal to the previous ones and located  also on the neck of the base bell, somewhat higher, at in order to raise the location of these, getting them to act before and therefore evacuate less water when making a total discharge of the cistern.

In this case the overflow pipe will have a additional anchor slot to interact with the buoys in this new position.

Another feature of the base bell is that its neck, which also serves as a lower guide to the overflow, incorporates some openings or windows that allow the performance of wedges protrusions of the articulated lower buoys to retain the tube or overflow for the duration of the download.

These windows will only be used in the case of locate the buoys on the shafts located at the bottom of the neck.

With this alternative in the location of the buoys  lower, the filling of the cistern occurs before if the buoys would have been mounted on the lower shafts, not producing the complete emptying of the liquid, this is achieved a complete and efficient enough download but saving a considerable volume of water.

To evacuate the water that makes buoys float At least one exit hole is included.

This hole empties the kind of glass that forms the base bell when the different pieces are mounted on it complementary that form the downloader.

It is also planned, in the event that the mentioned outlet hole is located on the side of said  glass, to regulate the water outlet, using a simple mobile shutter, consisting of a rotating ring that is mounted on The outside of the bell

Entering the different types of mechanisms  implementable, we have to when the downloader acts by pressing, either through a double download mechanism or by means of a total discharge mechanism, a bridge is planned support, whose lower base forms together with the base bell already mentioned inverted bell where the floats are located or articulated buoys.

In this case of the support bridge, the same incorporates anchoring means where other buoys are attached or adjustable top floats that are responsible for retaining the overflow at the desired height, depending on the desired volume or need to drain when a double discharge system is used. These anchoring means are aligned vertically with the lower float anchors to allow the use of similar or identical pieces.

When double discharge is used, the improvements of the invention allow us the possibility of use a single type of buoy, so that the two pairs of floats will be identical, and also, unlike patents already known the adjustable upper buoys are not mounted on the overflow tube, but as we have seen are articulated anchored on the support bridge, so that they are independent of displacements of said overflow tube, circumstance that does lighter by not relying on extra weights that hinder your movements.

The support bridge includes stops to limit the tilting of such floats.

Optionally said upper floats will go mounted on a complementary support piece, in which case it will be this is the one that is anchored to the desired height on the support bridge, being perfectly operational.

This alternative ensures that during assembly of the floats do not make mistakes when placing them at different heights on the support bridge, which would render the partial discharge system.

On the other hand, the drive device of the arrester may be constituted in principle by a classic wedge system that acts on a rocker, as per example the invention patent no. 9701529.

However, the drive device incorporates several new aspects that are detailed to continuation.

So, first, in the part of the bridge support there is a conduit that houses both a wedge that acts on the rocker, like an angular piece in charge of transmitting the movement from the push buttons.

Another feature of the device actuator of the arrester is that the articulation axis of the Rocker is displaced from the center of the unloader, in a Point next to the wedge area. In this way we gain smooth functioning, to which the small inclination towards the center that the wedge adopts when It acts on the rocker.

Another feature of the device actuator of the arrester is that the angular part referred to previously includes a recess to not limit the rise of the overflow, as well as nerves to reduce friction with the internal walls of the duct where the angular piece is guided by One of its branches. In turn, this conduit acts as an external guide superior also of the overflow in its vertical displacement.

The operation is similar to that of conventional arresters with the difference that it is not used a top buoy, mounted on the overflow, but two floats symmetrical mounted on independent axes identical to those lower and whose mission is to block the overflow at the height that desired, depending on the volume of water that is intended or desired to download.

So, once the cistern has been filled, the floats press with the projections or lugs on the overflow tube surface, as they tend to horizontality Due to its flotation.

When we act on the device drive, a certain distance (partial discharge) we raise the overflow tube until the buoys protrusions superiors are inserted into an annular recess of said overflow forcing him to maintain that position while the water goes descending until it releases the buoyancy of the buoys that tilt and release the overflow tube, which will fall producing the obturation. All this helped by the fraction of water that enter by the bypass slots that we have planned in the base bell

To make the total unloading the interlocking from the overflow then the lower buoys are made in another recessed from the overflow, so that it is not released until the water level of the tank has dropped below these and the inverted vessel, formed by the bridge junction, has been evacuated and the base bell.

The base bell also allows you to configure not only  double download downloaders, but full download downloaders, both by shooter and by push button.

This bell will then have a few lugs radial as means to mount a bridge with a system of shooter with eccentric. For the shooter mechanism to be extendable in height will be mounted on said base bell a over-bell that will perform the glass function inverted and through which the adjustable overflow will move in height, which will be guided superiorly by said over-bell

Always the element to mount on the hood base will support the elements that complement the downloader and in turn inverted glass; as we have commented previously.

Finally and as a manufacturing option and example  of the versatility of the base bell, the model is expected main double discharge can be manufactured with a single buoy bottom, using for interlocking or blocking the tube overflowing mobile wedges that, when said buoy floats, rub with the overflow reaching to block it when the ring recess is at the height of the ends in a phase of discharge total.

Finally, when the buoy stops floating, these wedges tilt, that is, open and stop rubbing on the overflow to lean on the guide neck, then at that time the shutter and / or end of the total discharge of the tank.

Next to facilitate a better understanding of this descriptive report and being an integral part of the same accompany some figures in which with character illustrative and not limiting the object of the invention.

Description of the preferred embodiment

An example of the invention according to the numbering adopted in the figures.

It comprises in principle a base bell 1 that it has a structure prepared to arrange on it the different elements, which will then constitute the downloader in their Different versions and realizations.

The base bell 1 has in principle some radial lugs 2 used as means of anchoring the pieces that form the body of the arrester.

The base bell 1 also includes narrow 5 slots additional to conventional evacuation windows 6, slots 5 that serve to derive part of the liquid after the discharge towards the upper face of the also conventional gasket shutter 7, during a partial discharge as already mentioned in the background section, so that in a download partial seal 7 assumes a lower position than during total download.

So, this small amount of water that passes through the slots 5 of the base bell 1, it will exert a pressure on the upper face of said joint 7 favoring its rapid descent (shutter) as soon as the volume of preset water and floats stop working.

The base bell 1 also incorporates shafts individual anchor and articulation 8 for the coupling of lower buoys 9.

It is important to facilitate the assembly of these buoys that the axes are individual and thus reduce also possible friction that could impair your mobility. These axes 8 include stops 10 to ensure perfect centering of each buoy.

The base bell includes a guide collar 11 where the overflow tube 20 is conducted and guided, incorporating that neck 11 openings 12 that allow the actuation of some lugs or projections 13 on the overflow tube 20. This allows us to arrange longer guiding length for overflow tube 20. The projections 13 are part of the lower buoys 9 and fit into an annular groove 33 provided for this purpose in the tube overflow.

On the other hand, to evacuate water from a inverted hood 3, which is part of the body of the arrester, is  has incorporated at least one outlet hole 14, which already they incorporated other conventional arresters.

When it comes to systems powered by pulsation (double discharge mechanism and discharge mechanism total) there is a new support bridge 15, whose lower base 16 forms next to the base bell 1, the aforementioned bell inverted 3 in which we will place the floats 9.

Optionally, base 16 could incorporate minus a side hole 17 to drain the water inside the inverted bell, of similar function as the mentioned hole 14 previously.

In the vertical sections of said support bridge 15 we have anchoring means determined by pairs of lugs 18 for mounting the top floats or buoys 19 that are they retain the overflow 20 at the desired height, in depending on the volume you want to discharge the tank when employs a double discharge system.

These anchoring means determined in pairs of studs 18 are aligned vertically with the anchors of bottom floats 9 to allow the use of parts identical.

In an optional embodiment (Figures 8 and 9), the upper floats 19 will be mounted directly on a new support piece 39, which will be anchored at the desired height above the support bridge 15 '.

For this, said support piece 39 will have 18 'pairs of lugs similar in shape and function to the lugs 18.

The whole set will be located on the support bridge, but this time using elastic projections 40 that will introduce in a new holes 41 communicated with each other by narrowings 42, so that the position of said elastic projections, and therefore, the location of the floats without the need to remove them from the line formed by said holes 41.

A gentle pressure towards the center of the arrester to align the mentioned holes 41 with the narrowing 43 of the elastic projections 40 so that these They can go up and down.

The support piece 39 incorporates reliefs lengths 44 that are inserted into guide grooves 45 of the bridge 15 'support, to avoid pitching of the assembly formed by the floats 19 and said support piece 39.

One of the most important advantages of this invention is the possibility of using a single type of buoy, it is that is to say, the four floats used in this arrester are identical, and also, unlike the already known patents, the adjustable buoys 19 are not mounted on the overflow tube 20, but as we have seen, they are articulated anchored in the support bridge 15, so that they are independent of the displacements of said overflow tube, which makes it lighter by not depending on extra weights that hinder your movements.

The support bridge includes stops 21 for limit float tilt 19.

Moreover, the drive device it is a classic wedge system 22 (invention patent nº 9701529) that acts on a rocker 23, which also presents certain new aspects, which are the following:

- It is arranged at the top of the bridge support 15 a conduit 24 housing both wedge 22 and the angular piece 25 responsible for transmitting the movement of the push buttons (located above plate 26 not shown).

- The articulation shaft 27 where the rocker 23 moves said axis from the center of the unloader bringing it closer to the wedge area 22. This allows gain displacement at the opposite end of rocker 23, winning so also in softness, to which the small inclination contributes towards the center that adopts said wedge 22 when acting on the rocker.

- The angular piece 25 includes a recess 28 for not limit the rise of overflow 20 and a few ribs 29 to reduce friction with the internal walls of the duct 24, which to  in turn it acts as a vertical guide for the movement of said tube overflow 20, which as we see, presents a small flange 30 that it glides smoothly on the outer face 31 of the mentioned duct 24.

It is important that overflow 20 goes up and down with absolute verticality to ensure operation Right.

The operation is similar to that of conventional arresters with the difference that it is not used a top buoy mounted on the overflow, but two floats symmetrical 19 mounted on independent shafts identical to the lower and whose mission is to block the overflow at the height that desired, depending on the volume of water desired to download.

In this sense, and once filled the cistern, the  floats 19 press with the protrusions 32 on the surface of the overflow tube 20, since they tend to horizontality due to its flotation

When we act on the device drive (disk or plate 26), a certain distance (partial discharge) we raise the overflow tube until the projections 32 of the lower buoys are inserted into a recess annul 33 of said overflow 20 forcing it to maintain that position meanwhile the water goes down until it releases buoyancy to buoys 19 that tilt and release the tube overflow 20, which falls causing the shutter. All helped by the fraction of water that is introduced through the slots of branch 5 provided in the base bell 1.

The volume of water evacuated, of course, will be based on the position in which we have located the buoys 19.

To perform the total discharge, the interlocking from the overflow the lower buoys 9 are made in another recessed annular 33, then it is not released until the level of water from the cistern has dropped below these and has Evacuated the inverted glass.

To turn this downloader into a system of total discharge, it is only necessary to disassemble the upper buoys 19.

To be an extensible shooter, the over-bell or semi-bell 4 with overflow tube 20 'height-adjustable, semi-bell that includes at least one side opening 38 for water evacuation.

This semi-bell 4 will have some lugs radial 34 for mounting a bridge 35 for a puller system with  eccentric 36.

As we see, the base bell 1 allows you to configure, not only double download downloaders, but download ones complete, both by shooter and by push button.

Optionally lower buoys 9 may be mounted on another pair of axes 8 '(Figures 9, 10) equal to those previous 8 and also located in neck 11 of the base bell 1 but somewhat higher, in order to raise the location of these buoys 9, getting them to act before and therefore evacuate less water when making a total discharge of the tank.

In this case the overflow tube 20 will have an additional anchor groove 33 for interacting with the buoys In this new position.

The windows 12 will only be used in the case of locate the buoys on the shafts located at the bottom of the neck and not in this new location.

With this alternative in the location of the buoys  lower 9, the filling of the cistern occurs before if said buoys 9 would have been mounted on the lower shafts 8, at the complete emptying of the liquid contained in the cistern, with this a complete and sufficient discharge is achieved effective but saving a considerable volume of water.

For the emptying of the water that makes these float lower buoys inside inverted hood 3, it is planned at least one outlet hole 14, 17, as we have already pointed out previously.

This hole completely empties this glass formed by the base bell when mounted on it different complementary pieces that form the unloader.

In this sense, it is planned to regulate the water outlet when done through hole 17, using a simple mobile shutter 46, consisting of a rotating ring that It is mounted on the outside of the inverted hood 3 or lower base 16, so that in both cases an interior space is created 47 limited laterally by a perimeter wall.

Finally and as a manufacturing option and example of the versatility of the base bell 1, the model is expected main double discharge can be manufactured with a single buoy lower 9 ', using for interlocking or blocking the tube overflow 20 moving wedges 37 which, when said buoy 9 'floats, rub over the overflow tube, blocking it when the recess 33 of the overflow is located at the height of its ends in A phase of total discharge.

When the buoy 9 'stops floating, said wedges 37 tilt, that is, open and stop rubbing over the overflow to lean on the guide neck 11, at that time the shutter and / or end of the total discharge of the cistern.
