    [0001] HEIGHT ADJUSTMENT DEVICE FOR TOILET TANK DISCHARGERS
    [0003] The present invention relates to a device for adjusting the height of a toilet tank flusher that provides a quick and precise adjustment of the height of the flush inside the cistern.
    [0005] State of the art
    [0007] Most toilet tank flushers are made up of a casing, which is mounted inside the tank in a fixed way; and a discharge device comprising a sealing element for the water outlet hole of the tank, said discharge body being movable relative to the casing. The flushing device is mechanically linked to an actuating device which is in turn linked to a pushbutton arranged on the lid of the cistern, so that when the pushbutton is pressed the actuating element causes the movement of the flushing device and the opening of the water outlet hole of the cistern, thus allowing it to be emptied.
    [0009] The pushbutton can be connected to the actuating device, for example, by means of a threaded housing in a support base, or it can act directly on the support base by contact, without a connection between both elements.
    [0011] When an unloader is mounted on a cistern for which it is not specifically designed, it is necessary to adjust the height of the actuating device to arrange the housing or support base of the push button at the height of the lid of the cistern in which the pushbutton, so that said pushbutton acts on the actuating device.
    [0013] There are different mechanisms for regulating the height of the actuating device of a flusher for toilet tanks, such as the one shown in ES 2151374 B1, which supports the actuating device and is capable of being connected at different heights of the casing.
    [0015] One of the problems with this type of device is that the height adjustment has to be done by trial and error, that is, they have to be set at a certain height and then place the cistern lid to check if the height is correct. If it is not, the operation must be repeated.
    [0017] In some types of arresters, the actuating device is formed by a support base on which the button is pressed and a rod attached to said base, where said rod transmits a movement to the discharge device caused by pressing the button. To be able to adjust the height of the support base, the actuating device comprises a threaded housing in correspondence with a thread on the stem, so that the height at which the stem is fixed in the housing can be adjusted by screwing or unscrewing said stem.
    [0019] Some unloaders of the type described in the previous paragraph have the same problems as those mentioned above, since the height adjustment has to be done by trial and error, and the tank cover has to be mounted and removed after each adjustment to check if the position is correct. Furthermore, in some of the arresters described, during the adjustment of the position of the rod, the discharge device must be locked with the sealing element in the correct position, since, if the discharge device is not blocked, the variation of the position of the stem would in turn affect the position of the sealing element. For this, disposable bolts are normally used that block the movement of the discharge device, and once the position of the support base has been adjusted, they must be removed and are of no use, in addition to that if a readjustment is required, there is no the part because it is usually lost or thrown away after the first adjustment.
    [0021] Document ES 1149184U describes a mechanism for adjusting the height of the support base in which the stem moves axially through a through conduit, comprising a clamping piece that, once the height of the support base has been adjusted, is arranged so that it avoids the displacement of the stem. The problem with the described mechanism is that, in the adjustment position (in which the clamping piece does not block the movement of the stem along the through conduit), the stem can move freely along said conduit, therefore, it may move downwards due to the action of gravity, before completing the adjustment operation. Furthermore, it is not explained in said document how the discharge body is blocked during the operation of adjusting the height of the support base.
    [0022] For its part, document EP3382114 describes a cisterns flusher for toilets that comprises a first mechanism for adjusting the height of an element on which a button formed by a plate that slides horizontally and blocks / unblocks the vertical movement of the element on the one that acts the button. In addition, it includes another vertical locking mechanism for the movement of the unloading mechanism formed by a clip that is inserted horizontally at the base of the mouth of the unloading mechanism and blocks its movement, having to be removed once the height of the Downloader. This mechanism has the same problems as mentioned above. First of all, when the plate is not inserted, and therefore the height of the element on which the pushbutton acts can be adjusted, this element lacks any retention and therefore it may shift downwards due to the action of gravity, before completing the adjustment operation. In addition, as mentioned above, the clip that blocks the movement of the release mechanism can be pulled or lost after a first adjustment, since it is removed after use.
    [0024] The object of the present invention is a mechanism for adjusting the height of a toilet tank flusher comprising locking elements of the flushing device during the flushing height adjustment operation that do not have to be removed after adjusting the the height, and that allows a gradual, fast and precise adjustment of the height of said unloader by means of the pressure exerted with the lid of the cistern on the height adjustment mechanism, avoiding the adjustment by trial and the fall by gravity of the element of height adjustment during adjustment operation.
    [0026] Explanation of the invention
    [0028] The height adjustment device for toilet tank flushers object of the invention comprises a blocking element of the flushing device during height adjustment and a height adjustment element capable of being arranged in two angular positions in a housing guide, a first position in which a small elastic retention is exerted against the height adjustment element that prevents it from moving vertically downwards with respect to said guide housing due to the action of gravity, but that does not prevent its displacement if a thrust force is exerted on said element of height regulation; and a second locking position in which the movement of the regulating element is completely impeded and therefore fixed in said guide housing.
    [0030] According to one embodiment, the height adjustment element is formed by a support base for the button (the button can be attached to said support base by means of a threaded housing in a support base or it can act directly on the support base by contact, without a connection between the two elements) and a stem that extends from the bottom of said support base (in operating position). Said stem comprises two opposing grooves, and two intermediate portions between said grooves.
    [0032] The height adjustment device also comprises an adjustment support that defines a housing-guide through which the stem moves axially. The housing-guide defined by the adjustment support is a through hole, with two opposing first flanges and two opposing second flanges on its inner faces. The first tabs are smaller or farther apart than the second tabs. When said first flanges are inserted between two grooves of the stem, the stem is in the adjustment position, and said first flanges exert an elastic retention, due to the nature and dimensions of the plastic material that form the flanges of the housing and the grooves of the stem. , which prevents it from moving axially downwards due to the action of gravity, but this elastic retention can be easily overcome by applying a small pressure, for example, by pushing with the lid of the cistern (with the base of the button fixed in it) down the stem. In the state mentioned, the second flanges do not produce any effect, since they face the intermediate portions of the stem, and therefore are not in contact and do not exert any retention. When the second flanges are inserted between two grooves on the stem, the stem is in the locked position, and said second flanges completely prevent the stem from moving. In this state the first flanges do not produce any effect since they are facing the intermediate portions of the stem. A quarter turn of the stem changes between the set position and the locked position or vice versa.
    [0034] In the adjustment position, the height adjustment element moves relative to the adjustment support, which remains fixed, while in the locked position they move steadily. integral, causing its movement (axially downwards), actuated by the button, the movement of the discharge device and therefore the opening of the valve and the emptying of the tank.
    [0035] In order to fix the position of the adjustment support during the unloader height adjustment operation, and thus prevent it from activating the discharge device, it comprises a set of notches on its perimeter edge, in correspondence with a set of projections formed on the inside face of a locking element that is normally arranged on the upper edge of the discharger housing. According to one embodiment option, the locking element is a ring that is inserted in the upper edge of the unloader housing that comprises a set of projections on its inner face and that is capable of adopting different angular positions with respect to its axis. In this way, when the unloader height adjustment operation is being carried out, the ring will be arranged in such a way that the projections on its inner face do not coincide with the notches made on the perimeter edge of the adjustment piece, preventing its displacement, this position being the adjustment position, said retaining stop projections exerting said adjustment piece. When the height of the unloader has been adjusted, a certain angle will be rotated on the ring, so that the projections on its inner face coincide with the notches made in the perimeter edge of the adjustment support, this being position the operating position. In this operating position the projections do not impede the vertical movement of the adjustment bracket.
    [0037] In the operating position, when the pushbutton is pressed, it transmits the movement to the support base, which causes the set of adjustment element and adjustment support to move axially downwards, the adjustment device actuating said movement of the adjustment support. flush, which releases the clogging of the cistern's flush hole.

    [0083] Description of the preferred embodiments of the invention
    [0085] In view of the aforementioned figures, and in accordance with the numbering adopted, an example of embodiment of the invention can be seen in them, which comprises the parts and elements that are indicated and described in detail below.
    [0087] Thus, as can be seen in the figures, a possible preferred embodiment of the height adjustment device object of the present invention essentially comprises the following elements:
    [0089] • A height adjustment element (1) formed by a support base (10) for the pushbutton and a stem (11), with a substantially rectangular cross section, which extends from the lower part of said support base (10 ) (in operating position). Said stem (10) comprises two grooves (12) arranged on two of their faces in opposition, and two intermediate portions (13) corresponding to the faces that do not comprise grooves. In figure 2 the height adjustment element (1) according to an embodiment of the present invention is shown.
    [0090] • A regulation support (2) that defines a housing-guide (20) through which the stem (11) moves axially. The housing-guide (20) defined by the adjustment support (2) is a through hole, comprising on its inner faces two first flanges (21) in opposition and two second flanges (22) in opposition. The first flanges (21) are capable of exerting an elastic retention against the movement of the stem (11) when they are inserted between two grooves (12) of the stem (11), this being the adjustment position. Once the second flanges (22) are inserted between two grooves (12) of the stem (11), they prevent its axial movement, this being the locking position. Furthermore, said regulation support (2) comprises a set of notches (23) on its perimeter edge. The first flanges (21) also prevent the rotation of the stem in the locked position during the unloader operation, and to produce the rotation of the stem it is necessary to apply a small torque manually on it, since the first flanges (21) They have to be slightly deformed to fit between two grooves (12) when it is intended to change from the locking position to the adjustment position.
    [0091] • A blocking element, formed by a ring (3) that comprises a slot (30) in one of its two lateral faces into which the upper edge of the casing (4) of the arrester is inserted. Said ring (3) further comprises a set of projections (31), in accordance with the notches (23) of the adjustment support (2), on its inner face and is capable of rotating with respect to the casing (4).
    [0093] In figure 4 the locking position between the height adjustment element (1) and the adjustment support can be observed, in which the second tabs (22) are inserted between two grooves (12) of the stem (11) .
    [0095] In figure 5 the adjustment position between the height adjustment element (1) and the adjustment support can be observed, in which the first tabs (21) are inserted between two grooves (12) of the stem (11) .
    [0097] Figures 6 to 8 show different states of the height adjustment device for toilet cistern flushers object of the present invention.
    [0099] Thus, figure 6 shows how the height adjustment element (1) and the adjustment support (2) are in the adjustment position, that is, the first tabs (21) are inserted between two grooves (12) of the stem (11). The ring (3) is in the adjustment position, that is, the projections (31) do not coincide with the notches (23) of the adjustment support, this position being the adjustment position, said retaining stop projections (31) exerting the axial downward movement of said adjustment piece (2).
    [0101] In this way, when the unloader is mounted on the tank, the height adjustment element is placed in the highest position, and with the button mounted on the tank cover, the cover is positioned so that the button contacts the tank. support base (10), and is pressed down until the lid is mounted on the cistern, so that the height of the unloader is precisely regulated.
    [0103] Once the previous operation has been carried out, the tank lid is removed again, and the height adjustment element (1) is turned a quarter turn, so that the second tabs (22) are inserted between two grooves (12) of the stem (11), leaving the height adjustment element (1) in the locked position, so that when the pushbutton acts on the support base (10), the movement is transmitted to the stem and in turn is transmitted to the regulation support (2). In addition, a rotation is made on the ring (3) so that the projections (31) coincide with the notches (23) of the perimeter edge of the adjustment support (2), remaining in the operating position, so that the vertical movement of the adjustment bracket. Thus, when the adjustment support makes a vertical downward movement actuated by the pushbutton, this actuates the discharge device that allows the tank to be emptied.
    [0105] Figure 7 shows the operating position of the device, at rest. Figure 8 shows the operating position of the device when the unloader button has been operated. In this operating position, when the button is actuated, the movable discharge body comprising the sealing element rises and causes the water to escape from the cistern.
