The cup cover lid consists of a solid body similar to the mouth (circular or oblong) and the seat has an annular or elliptical shape that follows the contour of the mouth of the cup; Some seats are shaped like a horseshoe. Said seat is used for complaints people sit on it and avoid contact directly with the surface of the cup; in some cases the seat is cushioned for comfort; while the lid allows to cover the mouth of the cup.
Uno de los principales problemas que se suscitan en el uso de los retretes es la falta de buenos hábitos; pues generalmente los usuarios no bajan la tapa, ni el asiento del retrete, lo que provoca inconvenientes en el uso por parte de otros usuarios sea hombre o mujer y más cuando se trata de uso por parte de los hombres que por lo general no levantan el asiento cuando usan un retrete para orinar, lo que implica que al orinar salpiquen y mojen con orina el asiento, provocando disgusto en los demás usuarios del retrete y provocando contaminación de la tapa que pudiera ser un foco de infección para los otros usuarios. One of the main problems that arise in the use of toilets is the lack of good habits; as users generally do not lower the lid, nor the toilet seat, which causes inconvenience in the use by other users, whether male or female and more when it comes to use by men who usually do not lift the seat when they use a toilet to urinate, which means that when they urinate they splash and wet the seat with urine, causing disgust in the other users of the toilet and causing contamination of the lid that could be a source of infection for the other users.

In general, the hydraulic drive mechanism for automatically lowering the lid and the seat of a toilet, when the water is discharged from the toilet tank, in accordance with the present invention, consists of a hydraulic force driven actuator consisting of a cylindrical body in "T" defining a threaded lower end adapted to receive in a threaded form a coupling element of the end of a water supply duct from a water supply source, an intermediate lateral bypass with threaded end adapted to receive a coupling element from the end of a water pipeline to the toilet water tank; and a threaded upper end adapted to receive with a perimeter seal element between these, a hollow intermediate cylindrical body with internal cord and internal transverse wall with a central hole; which in turn receives at its upper end with a perimeter seal element, the threaded bottom pin of a cylindrical upper cover with a vertical central hole of threaded wall, adapted to receive the threaded bottom end of a fixing element in a threaded way hollow of the mechanism to the toilet.
El ensamble descrito internamente aloja una base inferior próximo al extremo inferior del cuerpo cilindrico en forma de "T" que comprende un borde anular inferior con un orificio vertical en comunicación con un orificio transversal y una proyección cilindrica vertical con una cavidad en su extremo superior adaptada para acoplar a presión o en forma roscada el extremo inferior de un vástago de empuje que pasa a través del orificio central de la pared transversal interna de dicho cuerpo cilindrica intermedio y por el extremo inferior de dicho elemento de fijación hueco del mecanismo al retrete, y en cuyo extremo superior comprende una cavidad adaptada para recibir a presión o en forma roscada el extremo inferior de una flecha vertical de accionamiento que pasa a través de dicho elemento de fijación hueco del mecanismo al retrete; el extremo superior de dicha flecha vertical de accionamiento sobresale más allá del extremo de dicho elemento de fijación hueco del mecanismo al retrete y está roscado para recibir en forma roscada una leva de accionamiento que hará contacto físico con el canto inferior y posterior de la tapa y asiento convencionales de un retrete para impulsarlos y con la fuerza ejercida provocar su caída para cubrir la boca del retrete. The internally described assembly houses a lower base close to the lower end of the "T" shaped cylindrical body comprising a lower annular edge with a vertical hole in communication with a transverse hole and a vertical cylindrical projection with a cavity at its adapted upper end for pressure or threaded coupling the lower end of a thrust rod that passes through the central hole of the internal transverse wall of said intermediate cylindrical body and through the lower end of said hollow fastener of the mechanism to the toilet, and at the upper end of which it comprises a cavity adapted to receive under pressure or in a threaded form the lower end of a vertical drive arrow that passes through said hollow fixing element of the mechanism to the toilet; the upper end of said vertical drive arrow protrudes beyond the end of said hollow fixing element of the mechanism to the toilet and is threaded to receive in a threaded way an actuating cam that will make physical contact with the bottom and rear edge of the lid and Conventional seat of a toilet to propel them and with the force exerted cause their fall to cover the mouth of the toilet.
Dicho elemento de fijación hueco del mecanismo al retrete, consiste en un perno cilindrico hueco con extremo inferior roscado para roscarse en el orificio central vertical de pared roscada de dicha tapa superior cilindrica y en el extremo superior comprendiendo una ceja como elemento de tope que queda alojada en la cavidad de un elemento de fijación de la tapa y asiento al retrete; dicho elemento de fijación hueco del mecanismo al retrete pasa a través de una de las cavidades de los elementos de fijación de la tapa y asiento y de uno de los orificios practicados en la parte posterior y superior del retrete para fijar el mecanismo al retrete y al mismo tiempo la tapa y asiento al retrete. Said hollow fixing element of the mechanism to the toilet, consists of a hollow cylindrical bolt with threaded lower end to be threaded into the vertical central threaded wall hole of said cylindrical upper cover and at the upper end comprising an eyebrow as a stopper element that is housed in the cavity of a fixing element of the lid and seat to the toilet; said hollow fixing element of the mechanism to the toilet passes through one of the cavities of the elements of fixing the cover and seat and one of the holes made in the back and top of the toilet to fix the mechanism to the toilet and at the same time the cover and seat to the toilet.
Dicho elemento de fijación hueco, además comprende una cuerda en una porción próxima al extremo superior, adaptada para recibir en forma roscada una tuerca que será la que presionará y fijará contra la superficie inferior del retrete, Said hollow fixing element also comprises a rope in a portion close to the upper end, adapted to receive a threaded nut which will be the one that will press and fix against the lower surface of the toilet,
Dicho vástago de empuje comprende un elemento de resorte envolvente que topa en la parte interna transversal de dicho cuerpo cilindrica intermedio, y funge como medio de retroceso para regresar en ensamble base inferior-vástago de empuje-flecha vertical de accionamiento-leva de accionamiento a su posición de reposo cuando no existe una fuerza por el flujo de agua a través del extremo inferior de dicho cuerpo en forma de "T". Said push rod comprises a wrap-around spring element that bumps into the transverse internal part of said intermediate cylindrical body, and serves as a means of recoil to return in lower base assembly-push rod-vertical drive shaft-drive cam to its resting position when there is no force for the flow of water through the lower end of said "T" shaped body.
El ensamble del mecanismo comprende un elemento sujetador indicador de presión que se acopla externamente entre cuerpo en forma de "T", el cuerpo cilindrico intermedio hueco y la tapa superior cilindrica. The assembly of the mechanism comprises a pressure indicating fastener that is externally coupled between a "T" shaped body, the hollow intermediate cylindrical body and the upper cylindrical cover.
Cuando existe una presión menor en el tanque de agua del retrete debido a la acción de desagüe del retrete, es decir cuando se acciona la palanca o botón de desagüe del tanque hacia el retrete para la descarga de los desechos, se crea un diferencial de presión en el interior del mecanismo permitiendo que el agua que viene del ducto de suministro de agua desde la fuente de suministro conectada en el extremo inferior del cuerpo cilindrico en "T", ofrezca mayor presión, haciendo que el agua desplace hacia arriba la base inferior la cual tiene acoplado el vástago de empuje y por ende es también desplazado hacia arriba y al estar conectado a la flecha vertical de accionamiento que comprende en su extremo superior la leva de accionamiento, también se desplaza hacia arriba empujando el borde posterior de la tapa y asiento para impulsarlos y bajarlos para cubrir la boca del retrete; el agua continúe su camino por la derivación lateral donde se conecta el ducto de alimentación de agua al tanque de agua del retrete para llenarlo; una vez que se llena el tanque del retrete, se iguala la presión dentro del actuador y el elemento de resorte regresa el ensamble base inferior-vástago de empuje-flecha vertical de accionamiento-leva de accionamiento a su posición inicial de reposo. When there is a lower pressure in the toilet water tank due to the drain action of the toilet, that is when the lever or drain button of the tank is operated towards the toilet for the discharge of waste, a pressure differential is created inside the mechanism allowing the water coming from the water supply pipeline from the supply source connected at the lower end of the "T" cylindrical body, to offer greater pressure, causing the water to move the lower base upwards. which has the push rod attached and therefore is also displaced upwards and being connected to the vertical drive arrow which comprises the drive cam at its upper end, also moves upwards by pushing the rear edge of the cover and seat to propel and lower them to cover the mouth of the toilet; the water continues its way through the side bypass where the water supply pipe is connected to the toilet water tank to fill it; once the toilet tank is filled, the pressure inside the actuator is equalized and the spring element returns the lower base assembly - push rod - vertical drive shaft - drive cam to its initial resting position.
Dicha base inferior donde se acopla el vástago de empuje comprende dicho elemento de sello perimetral que consiste preferiblemente en un "O'ring V de neopreno, que le ayuda a mantener el agua ejerciendo presión en la cara inferior de dicha base inferior del vástago. Cuando el tanque de agua del retrete se llena y cierra su compuerta de paso del agua, el diferencial de presión es cero dentro del ensamble del mecanismo; y el elemento de resorte que envuelve el vástago de empuje facilita el retorno y el reposicionamiento de dicho vástago a su posición de inicio; lo mimos que se genera en la flecha y en la leva de accionamiento que es regresada a su posición de inicio por efecto del elemento de resorte. Said lower base where the thrust rod is coupled comprises said perimeter seal element which preferably consists of a "O ' ring V of neoprene, which helps it maintain water by exerting pressure on the lower face of said lower stem base. When the toilet water tank fills and closes its water gate, the pressure differential is zero inside the mechanism assembly; and the spring element that envelops the push rod facilitates the return and repositioning of said rod to its starting position; the pampering that is generated on the arrow and on the drive cam that is returned to its starting position by the spring element.
Además para que se pueda desplazar el ensamble de la base inferior-flecha vertical de accionamiento-leva de accionamiento, a su posición de inicio y esto sea más rápido; el orificio vertical en comunicación con el orificio transversal, permiten el paso de un volumen de agua que le permite desplazase con mayor facilidad a la posición de inicio. Also so that the lower base-vertical drive-drive cam assembly can be moved to its starting position and this is faster; The vertical hole in communication with the transverse hole, allows the passage of a volume of water that allows it to move more easily to the starting position.
En otra de las modalidades de la invención, la base inferior, el vástago de empuje, la flecha vertical de accionamiento y la leva de accionamiento, conforman un cuerpo unitario, es decir una sola pieza. Por lo tanto, lo descrito anteriormente se resume en que el ensamble de la base inferior donde se acopla el vástago de empuje en el que se acopla a su vez la flecha de accionamiento y en ésta la leva de accionamiento, tiene un desplazamiento vertical, hacia arriba cuando el diferencial de presión es diferente de cero, y hacia abajo cuando hay un equilibrio de presión y el diferencial de presión es cero. In another embodiment of the invention, the lower base, the push rod, the vertical drive arrow and the drive cam, form a unitary body, that is to say a single piece. Therefore, what is described above is summarized in that the assembly of the lower base where the push rod in which the drive shaft is coupled is coupled and in this the drive cam, has a vertical displacement, towards up when the pressure differential is different from zero, and down when there is a pressure balance and the pressure differential is zero.
El mecanismo como descrito permite bajar la tapa y el asiento simultáneamente cuando ambos están en posición vertical o bajar solamente la tapa cuando ésta se encuentra en posición vertical y el asiento está en posición horizontal entorno a la boca del retrete. En otra de las modalidades de la invención, se incluye al menos un elemento para frenar y amortiguar la caída de la tapa y el asiento del retrete que se dispone por encima de la superficie de la boca del retrete para amortiguar la caída de la tapa y el asiento. The mechanism as described allows the lid and the seat to be lowered simultaneously when both are in an upright position or only to lower the cover when it is in an upright position and the seat is in a horizontal position around the mouth of the toilet. In another embodiment of the invention, at least one element is included to brake and dampen the fall of the lid and the toilet seat that is disposed above the surface of the mouth of the toilet to dampen the fall of the lid and the seat.
Una de las modalidades de dicho al menos un elemento para frenar y amortiguar la caída de la tapa y el asiento, consiste preferiblemente en un par de semiesferas neumáticas que alojan un volumen de aire, las cuales se fijan sobre el retrete en el borde de la parte posterior por la zona donde se fijan la tapa y el asiento. Dicho par de semiesferas neumáticas definen una pared en forma de domo y una base plana horizontal de mayor espesor y un poco más rígida, que puede comprender un adhesivo, una cinta de doble cara o algún otro medio de fijación o unión sobre el retrete; dicha base plana horizontal define una cavidad central y un orificio para entrada y salida de aire, donde se dispone una membrana que tiene un pequeño orificio que permite la salida lenta del aire contenido para frenar y amortiguar la caída del asiento y la tapa cuando estas caen sobre ellas; y una vez que se vacía ante la acción del peso de la tapa o el asiento; cuando dicha tapa y/o asiento se levantan, se vuelven a llenar con rapidez de aire por la configuración de la membrana que actúa como válvula tipo check, pues dicha membrana comprende un extremo sin fijación que permite mantenerse en posición cuando la semiesfera está llena de aire, dejándolo salir lentamente por el orificio central y cuando está vacía o semivacía permite que la fuerza de entrada de aire por efecto del vacío interior, levante el extremo sin unir de la membrana para generar un orifico de mayor dimensión que permite una mayor velocidad y flujo de aire entrante para un rápido llenado. One of the modalities of said at least one element for braking and damping the fall of the cover and the seat, preferably consists of a pair of pneumatic hemispheres that house a volume of air, which are fixed on the toilet at the edge of the back by the area where the cover and seat are fixed. Said pair of pneumatic hemispheres defines a dome-shaped wall and a horizontal flat base of greater thickness and a little more rigid, which may comprise an adhesive, a double-sided tape or some other means of fixing or joining on the toilet; said horizontal flat base defines a central cavity and an orifice for air inlet and outlet, where a membrane that has a small hole that allows the slow exit of the contained air to stop and cushion the fall of the seat and the cover when they fall on them; and once it is emptied by the action of the weight of the lid or the seat; when said cover and / or seat are lifted, they are quickly refilled with air by the configuration of the membrane that acts as a check valve, since said membrane comprises an end without fixation that allows it to remain in position when the hemisphere is full of air, letting it out slowly through the central hole and when it is empty or semi-empty allows the air inlet force due to the effect of the internal vacuum, lift the unbound end of the membrane to generate a larger hole that allows greater speed and Incoming air flow for rapid filling.
Una de dichas semiesferas se dispone por debajo del asiento, para frenar y amortiguar su caída y la segunda semiesfera se dispone detrás del asiento y detrás de la tapa, requiriendo de un brazo de palanca auxiliar para frenar y amortiguar la caída de la tapa. Dicho elemento de palanca consta de una placa de fijación con un orificio para recibir el mismo medio de fijación con que se fijan la tapa y el asiento al retrete, de modo que dicho elemento de palanca se fija sobre el retrete quedando detrás de la tapa y el asiento y un brazo de palanca fijo pivotalmente a dicha placa de fijación que se extiende hacia el frente; en donde la sección de la zona proximal a la unión pivotal se dispone sobre dicha segunda semiesfera y la sección extrema se extiende para disponerse sobre el asiento y debajo de la tapa; de modo que cuando la tapa esta levantada y se hace bajar por efecto del mecanismo de accionamiento hidráulico para bajarla automáticamente cuando se descarga el tanque de agua, el brazo de palanca recibe la cara inferior del asiento y al estar sobre dicha segunda semiesfera se frena y amortigua la caída, mientras va saliendo el aire del interior de dicha semiesfera. One of said hemispheres is disposed below the seat, to slow down and cushion its fall and the second hemisphere is disposed behind the seat and behind the lid, requiring an auxiliary lever arm to brake and dampen the fall of the lid. Said lever element consists of a fixing plate with a hole for receiving the same fixing means with which the lid and the seat are fixed to the toilet, so that said lever element is fixed on the toilet being behind the lid and the seat and a lever arm pivotally fixed to said fixing plate which extends towards the front; wherein the section of the area proximal to the pivotal joint is disposed on said second hemisphere and the end section extends to be disposed on the seat and under the cover; so that when the lid is lifted and lowered by the effect of the hydraulic drive mechanism to automatically lower it when the water tank is discharged, the lever arm receives the lower face of the seat and being on said second hemisphere brakes and it dampens the fall, while the air inside the said hemisphere comes out.
En otra de la modalidades de la invención, dicho al menos un elemento para frenar y amortiguar la caída de la tapa y el asiento consiste en un par de ensambles de freno uno para el asiento y otro para la tapa. Ambos tienen la misma configuración y constan de una placa base que presentan una ranura alargadas para recibir los medios de fijación que fijan a la tapa y el asiento y uno de ellos también al mecanismo de accionamiento hidráulico para bajar la tapa y el asiento; dichos ensambles de freno se fijan entonces con los mismos medios de fijación de la tapa y el asiento y quedan dispuestos detrás de éstos. In another of the embodiments of the invention, said at least one element for braking and damping the fall of the cover and the seat consists of a pair of brake assemblies one for the seat and one for the cover. Both have the same configuration and consist of a base plate that have an elongated groove to receive the fixing means that fix to the cover and the seat and one of them also to the hydraulic drive mechanism to lower the cover and the seat; said brake assemblies are then fixed with the same fixing means of the cover and the seat and are arranged behind them.
En el extremo de la placa se comprende fijamente una carcasa para alojar y fijar un freno hidráulico que comprende una oquedad centran adaptada para recibir el extremo de un perno, cuyo extremo opuesto se conecta a un brazo de palanca monolítico que define un cuerpo hueco que recibe dicho perno, una barra perpendicular a este cuerpo hueco y una segunda barra hueca perpendicular a al primera barra, de modo que se define un brazo angulado. Dicha carcasa comprende un par de oquedades inferiores adaptadas para recibir y fijar el extremo de un elemento de resorte que envuelve a dicho cuerpo hueco y cuyo extremo opuesto de dicho elemento de resorte se aloja en dicho segunda barra hueca del brazo angulado. Dicho elemento de resorte permite mantener el brazo de palanca en posición erguida. At the end of the plate there is a fixed housing for housing and fixing a hydraulic brake comprising a central recess adapted to receive the end of a bolt, the opposite end of which is connected to a monolithic lever arm that defines a hollow body that receives said bolt, a bar perpendicular to this hollow body and a second hollow bar perpendicular to the first bar, so that an angled arm is defined. Said housing comprises a pair of lower recesses adapted to receive and fix the end of a spring element that envelops said hollow body and whose opposite end of said spring element is housed in said second hollow bar of the angled arm. Said spring element allows to keep the lever arm in an upright position.
Uno de dichos brazos de palanca (específicamente la segunda barra hueca) de uno de dichos ensambles de freno se dispone debajo del asiento y el otro debajo de la tapa y sobre el asiento. Ambos se mantienen erguidos por efecto del elemento de resorte y cuando el asiento o la tapa o ambos caen cuando son empujados por la leva de accionamiento del mecanismo de accionamiento hidráulico para bajarlos, es decir cuando se acciona la palanca o botón de desagüe del tanque hacia el retrete para la descarga de los desechos; dichos brazos de palanca (específicamente la segunda barra hueca) detienen el asiento o la tapa o ambos frenando su caída y haciéndola lenta, venciendo la fuerza el freno hidráulico y del elemento de resorte. Cuando la tapa y/o el asiento se levantan, dicho elemento de resorte regresa a dichos brazos de palanca a una posición erguida. One of said lever arms (specifically the second hollow bar) of one of said brake assemblies is arranged under the seat and the other under the cover and on the seat. Both are held up by the effect of the spring element and when the seat or the cover or both fall when they are pushed by the drive cam of the hydraulic drive mechanism to lower them, that is to say when the tank drain lever or button is operated towards the toilet for the discharge of waste; said lever arms (specifically the second hollow bar) stop the seat or the cover or both slowing its fall and making it slow, the hydraulic brake and the spring element overcoming the force. When the cover and / or the seat are lifted, said spring element returns to said lever arms to an upright position.

Referring to Figures 1 to 4, the hydraulic drive mechanism for automatically lowering the lid and the seat of a toilet when the water is discharged from the tank, in accordance with the present invention, consists of an actuator driven by hydraulic force 1 consisting of of a "T" cylindrical body 2 defining a threaded lower end 3 adapted to receive in threaded form a coupling element 4 of the end of a water supply duct 5 from a water supply source; an intermediate lateral branch 6 with threaded end adapted to receive a coupling element 7 from the end of a water conduit duct 8 towards the water tank 9 of the toilet; and a threaded upper end 10 adapted to receive, with a perimeter seal element 11 between them, a hollow intermediate cylindrical body 12 with internal cord and internal transverse wall 13 with a central hole 14; which in turn receives at its upper end, with a perimeter seal element 15, the threaded lower pin 16 of a cylindrical upper cover 17 with a vertical central hole of threaded wall 18, adapted to receive the threaded surface 19 of a hollow fixing element 20 of the mechanism to the toilet.
El ensamble descrito aloja internamente una base inferior 21 próximo al extremo inferior del cuerpo cilindrico en forma de "T" 2 con un elemento de sello anular 21 a, que comprende un borde anular inferior 22 con un orificio vertical (no mostrado) en comunicación con un orificio transversal 23 y una proyección cilindrica vertical 24 con una cavidad en su extremo superior 25 adaptada para acoplar a presión o en forma roscada el extremo inferior de un vástago de empuje 26 que pasa a través del orificio central 14 de la pared transversal interna 13 de dicho cuerpo cilindrica intermedio 12 y por el extremo inferior de dicho elemento de fijación hueco 20 del mecanismo al retrete, y en cuyo extremo superior 27 comprende una cavidad adaptada para recibir a presión o en forma roscada el extremo inferior 28 de una flecha vertical de accionamiento 29 que pasa a través de dicho elemento de fijación hueco 20 del mecanismo al retrete; el extremo superior de dicha flecha vertical de accionamiento 29 sobresale más allá del extremo de dicho elemento de fijación hueco 20 del mecanismo al retrete y está roscado para recibir en forma roscada una tuerca 30 donde se acopla una leva de accionamiento 31 que hará contacto físico con el canto inferior y posterior de la tapa 32 y asiento 33 convencionales de un retrete 34 para impulsarlos y con la fuerza ejercida provocar su caída para cubrir la boca del retrete 34. The described assembly internally houses a lower base 21 near the lower end of the "T" shaped cylindrical body 2 with an annular seal element 21 a, comprising a lower annular edge 22 with a vertical hole (not shown) in communication with a transverse hole 23 and a vertical cylindrical projection 24 with a cavity at its upper end 25 adapted to engage press or threaded the lower end of a push rod 26 which passes through the central hole 14 of the internal transverse wall 13 of said intermediate cylindrical body 12 and through the lower end of said hollow fastener 20 of the toilet mechanism , and at whose upper end 27 it comprises a cavity adapted to receive under pressure or in threaded form the lower end 28 of a vertical drive arrow 29 that passes through said hollow fixing element 20 of the mechanism to the toilet; the upper end of said vertical drive arrow 29 protrudes beyond the end of said hollow fastener 20 of the mechanism to the toilet and is threaded to receive a threaded nut 30 where a drive cam 31 is coupled which will make physical contact with the lower and rear edge of the lid 32 and conventional seat 33 of a toilet 34 to propel them and with the force exerted cause it to fall to cover the mouth of the toilet 34.
Dicho elemento de fijación hueco 20 del mecanismo al retrete, consiste en un perno cilindrico hueco con extremo inferior roscado 19 para roscarse en el orificio central vertical de pared roscada 18 de dicha tapa superior cilindrica 17 y en el extremo superior comprendiendo una ceja 35 como elemento de tope que queda alojada en la cavidad 36 de un elemento de fijación 37 de la tapa 32 y asiento 33 al retrete 34; dicho elemento de fijación hueco 20 del mecanismo al retrete pasa a través de una de las cavidades 36 de los elementos de fijación 37 de la tapa 32 y asiento 33, y de uno de los orificios (no mostrados) practicados en la parte posterior y superior del retrete 34 para fijar el mecanismo al retrete y al mismo tiempo la tapa 32 y asiento 33 al retrete 34. Said hollow fixing element 20 of the mechanism to the toilet, consists of a hollow cylindrical bolt with threaded lower end 19 for threading into the vertical central threaded wall hole 18 of said upper cylindrical cover 17 and at the upper end comprising an eyebrow 35 as an element stop which is housed in the cavity 36 of a fastener 37 of the cover 32 and seat 33 to the toilet 34; said hollow fixing element 20 of the toilet mechanism passes through one of the cavities 36 of the fixing elements 37 of the cover 32 and seat 33, and of one of the holes (not shown) made in the rear and upper part of the toilet 34 to fix the mechanism to the toilet and at the same time the cover 32 and seat 33 to the toilet 34.
Dicho elemento de fijación hueco 20, además comprende una cuerda exterior 38, adaptada para recibir en forma roscada una tuerca de fijación 39 que será la que presionará y fijará contra la superficie inferior del retrete 34. Said hollow fixing element 20 also comprises an outer rope 38, adapted to receive a threaded nut 39 which will be the one that will press and fix against the bottom surface of the toilet 34.
Dicho vástago de empuje 26 comprende un elemento de resorte envolvente 40 como medio de retroceso para regresarlo a su posición de reposo cuando no existe una fuerza por el flujo de agua a través del extremo inferior 3 de dicho cuerpo en forma de "T" 2. Haciendo referencia a las figuras 6a hasta 6d muestran en vista lateral un retrete 34 con tapa 32 y asiento 33 convencionales, en el que se encuentra instalado el mecanismo de accionamiento hidráulico 1 para bajar automáticamente la tapa y el asiento, mostrando el accionamiento para bajar simultáneamente la tapa 32 y el asiento 33 de forma automática cuando se acciona el botón de descarga de agua 41 del tanque 9 del retrete 34 para la evacuación de los desechos. En donde cuando existe una presión menor en el tanque de agua 9 del retrete 34 debido a la acción de desagüe del retrete, es decir cuando se acciona el botón de desagüe 41 hacia el retrete para la descarga de los desechos, se crea un diferencial de presión en el interior del mecanismo 1 , permitiendo que el agua que viene del ducto de suministro de agua 5 desde la fuente de suministro conectada en el extremo inferior del cuerpo cilindrico en "T" 2, ofrezca mayor presión, haciendo que el agua desplace hacia arriba en ensamble de la base inferior 21 acoplada al vástago de empuje 26, que a su vez está conectado a la flecha vertical de accionamiento 29 que en su extremo superior comprende la leva de accionamiento 31 (ver figuras 1 y 4) que empujará el borde posterior de la tapa 32 y asiento 33 para impulsarlos y bajarlos para cubrir la boca del retrete 34; el agua continúa su camino por la derivación lateral donde se conecta el ducto de alimentación de agua 8 al tanque de agua 9 para llenarlo. Said push rod 26 comprises a wrapping spring element 40 as a means of recoil to return it to its resting position when there is no force by the flow of water through the lower end 3 of said "T" shaped body 2. Referring to Figures 6a to 6d, they show in side view a toilet 34 with a cover 32 and a conventional seat 33, in which the hydraulic drive mechanism 1 is installed to automatically lower the cover and the seat, showing the drive to lower simultaneously the cover 32 and the seat 33 automatically when the water discharge button 41 of the tank 9 of the toilet 34 is operated for the disposal of the waste. Where there is a lower pressure in the water tank 9 of the toilet 34 due to the drainage action of the toilet, that is to say when the drain button 41 is operated towards the toilet for the discharge of the waste, a pressure differential is created inside the mechanism 1, allowing the water coming from the water supply duct 5 from the supply source connected at the lower end of the "T" cylindrical body 2, offers greater pressure, causing the water to move upwards in assembly of the lower base 21 coupled to the push rod 26, which in turn is connected to the vertical drive arrow 29 which at its upper end comprises the drive cam 31 (see figures 1 and 4) that will push the rear edge of the cover 32 and seat 33 to push them and lower them to cover the mouth of the toilet 34; the water continues its way through the side bypass where the water supply pipe 8 is connected to the water tank 9 to fill it.
Una vez que se llena el tanque del retrete, se iguala la presión dentro del actuador 1 y el elemento de resorte 40 regresa el ensamble base inferior 21 -vástago de empuje 26-flecha vertical de accionamiento 29-leva de accionamiento 31 (ver figuras 1 a 4) a su posición inicial de reposo. Once the toilet tank is filled, the pressure inside the actuator 1 is equalized and the spring element 40 returns the lower base assembly 21 - push rod 26-vertical drive arrow 29-drive cam 31 (see figures 1 a 4) to its initial resting position.
Con referencia a las figuras 7 a 7d, los elementos para frenar y amortiguar la caída de la tapa y el asiento constan de un par de semiesferas neumáticas 43a y 43b que alojan un volumen de aire, las cuales se fijan sobre el retrete 34 en el borde de la parte posterior por la zona donde se fijan la tapaWith reference to Figures 7 to 7d, the elements for braking and cushioning the fall of the cover and the seat consist of a pair of pneumatic hemispheres 43a and 43b that house a volume of air, which are fixed on the toilet 34 in the edge of the back by the area where the lid is fixed
32 y el asiento 33. Dicho par de semiesferas neumáticas 43a y 43b definen una pared en forma de domo 44 y una base plana horizontal 45 de mayor espesor y un poco más rígida, que puede comprender un adhesivo, una cinta de doble cara o algún otro medio de fijación o unión (no mostrado) para fijarse sobre el retrete 34; dicha base plana horizontal 45 define una cavidad central 46 y un orificio para entrada y salida de aire 47, donde se dispone una membrana 48 que tiene un pequeño orificio 49 que permite la salida lenta del aire contenido para frenar y amortiguar la caída del asiento32 and the seat 33. Said pair of pneumatic hemispheres 43a and 43b define a dome-shaped wall 44 and a horizontal flat base 45 of greater thickness and a little more rigid, which may comprise an adhesive, a double-sided tape or some other means of attachment or attachment (not shown) to be fixed on the toilet 34; said horizontal flat base 45 defines a central cavity 46 and an orifice for air inlet and outlet 47, where a membrane 48 is provided that has a small hole 49 that allows the slow exit of the contained air to slow down and dampen the seat drop
33 y la tapa 32 cuando estas caen sobre ellas; y una vez que se vacía ante la acción del peso de la tapa o el asiento; cuando dicha tapa y/o asiento se levantan, se vuelven a llenar con rapidez de aire por la configuración de la membrana 48 que actúa como válvula tipo check, pues dicha membrana comprende un extremo 48a sin fijación que permite mantenerse en posición cuando la semiesfera está llena de aire, dejándolo salir lentamente por el orificio central y cuando está vacía o semivacía permite que la fuerza de entrada de aire por efecto del vacío interior, levante el extremo sin unir 48a de la membrana 48 para generar un orifico de mayor dimensión que permite una mayor velocidad y flujo de aire entrante para un rápido llenado. 33 and cover 32 when they fall on them; and once it is emptied by the action of the weight of the lid or the seat; when said cover and / or seat are lifted, they are quickly refilled with air by the configuration of the membrane 48 that acts as a check type valve, since said membrane comprises an end 48a without fixation that allows it to remain in position when the hemisphere is filled with air, letting it out slowly through the central hole and when it is empty or semi-empty it allows the air inlet force due to the effect of the internal vacuum, to lift the unbound end 48a of the membrane 48 to generate an orifice of greater dimension that allows Higher speed and incoming air flow for rapid filling.
La semiesfera 43a se dispone por debajo del asiento 33, para frenar y amortiguar su caída y la segunda semiesfera 43b se dispone detrás del asiento 33 y detrás de la tapa 32 (ver fig. 7a y 7d), requiriendo de un brazo de palanca auxiliar 50 para frenar y amortiguar la caída de la tapa 32. Dicho elemento de palanca 50 consta de una placa de fijación 51 con un orificio para recibir el mismo medio de fijación con que se fijan la tapa y el asiento al retrete 34, de modo que dicho elemento de palanca 50 se fija sobre el retrete quedando detrás de la tapa 32 y el asiento 33 y un brazo de palanca 52 fijo pivotalmente a dicha placa de fijación 51 que se extiende hacia el frente; en donde la sección de la zona proximal a la unión pivotal se dispone sobre dicha segunda semiesfera 43b y la sección extrema se extiende para disponerse sobre el asiento 33 y debajo de la tapa 32; de modo que cuando la tapa 32 esta levantada y se hace bajar por efecto del mecanismo de accionamiento hidráulico para bajarla automáticamente cuando se descarga el tanque de agua, el brazo de palanca 52 recibe la cara inferior del asiento 32 y al estar sobre dicha segunda semiesfera 43b se frena y amortigua la caída, mientras va saliendo el aire del interior de dicha semiesfera 43b. The hemisphere 43a is disposed below the seat 33, to stop and cushion its fall and the second hemisphere 43b is disposed behind the seat 33 and behind the cover 32 (see figs. 7a and 7d), requiring an auxiliary lever arm 50 to stop and dampen the fall of the lid 32. Said lever element 50 consists of a fixing plate 51 with a hole for receiving the same means. for fixing the cover and the seat to the toilet 34, so that said lever element 50 is fixed on the toilet being behind the lid 32 and the seat 33 and a lever arm 52 pivotally fixed to said plate of fixation 51 extending towards the front; wherein the section of the area proximal to the pivotal joint is disposed on said second hemisphere 43b and the end section extends to be disposed on the seat 33 and under the cover 32; so that when the cover 32 is lifted and lowered by the effect of the hydraulic drive mechanism to automatically lower it when the water tank is discharged, the lever arm 52 receives the lower face of the seat 32 and being on said second hemisphere 43b slows down and dampens the fall, while the air inside the said hemisphere 43b rises.
Haciendo referencia a las figura 8 a 9b, dicho al menos un elemento para frenar y amortiguar la caída de la tapa y el asiento consiste en un par de ensambles de freno 53a y 53b uno para el asiento 33 y otro para la tapa 32. Ambos tienen la misma configuración y constan de una placa base 54 que presentan una ranura alargadas 55 para recibir los medios de fijación que fijan a la tapa 32 y el asiento 33 y uno de ellos también al mecanismo de accionamiento hidráulico para bajar la tapa y el asiento; dichos ensambles de freno se fija entonces con los mismos medios de fijación huecos 20 de la tapa 32 y el asiento 33 y quedan dispuestos detrás de éstos. Referring to Figures 8 to 9b, said at least one element for braking and damping the fall of the cover and the seat consists of a pair of brake assemblies 53a and 53b one for the seat 33 and one for the cover 32. Both they have the same configuration and consist of a base plate 54 that have an elongated groove 55 to receive the fixing means that fix to the cover 32 and the seat 33 and one of them also to the hydraulic drive mechanism to lower the cover and the seat ; said brake assemblies are then fixed with the same hollow fixing means 20 of the cover 32 and the seat 33 and are arranged behind them.
En el extremo de la placa 54 se comprende fijamente una carcasa 56 para alojar y fijar un freno hidráulico 57 que comprende una oquedad centran 58 adaptada para recibir el extremo de un perno 59, cuyo extremo opuesto se conecta a un brazo de palanca 60 monolítico que define un cuerpo hueco 61 que recibe dicho perno 59, una barra perpendicular 62 a este cuerpo hueco 61 y una segunda barra hueca 63 perpendicular a al primera barra 62, de modo que se define un brazo angulado. Dicha carcasa 56 comprende un par de oquedades inferiores 64 adaptadas para recibir y fijar el extremo de un elemento de resorte 65 que envuelve a dicho cuerpo hueco 61 y cuyo extremo opuesto de dicho elemento de resorte se aloja en dicho segunda barra hueca 63 del brazo angulado. Dicho elemento de resorte 65 permite mantener el brazo de palanca en posición erguida. At the end of the plate 54 a housing 56 is fixedly fixed to accommodate and fix a hydraulic brake 57 comprising a central cavity 58 adapted to receive the end of a bolt 59, whose opposite end is connected to a monolithic lever arm 60 which it defines a hollow body 61 that receives said bolt 59, a perpendicular bar 62 to this hollow body 61 and a second hollow bar 63 perpendicular to the first bar 62, so that an angled arm is defined. Said housing 56 comprises a pair of lower recesses 64 adapted to receive and fix the end of a spring element 65 that surrounds said hollow body 61 and whose opposite end of said spring element is housed in said second hollow bar 63 of the angled arm . Said spring element 65 allows the lever arm to be held in an upright position.
Dicha segunda barra hueca 63 del ensamble de freno 53a se dispone debajo del asiento 33 y dicha segunda barra hueca 63 del segundo ensamble de freno 53b debajo de la tapa 32 y sobre el asiento. Ambos se mantienen erguidos por efecto del elemento de resorte 65 y cuando el asiento o la tapa o ambos caen cuando son empujados por la leva de accionamiento del mecanismo de accionamiento hidráulico (ver figuras 1 a 6) para bajarlos, es decir cuando se acciona la palanca o botón de desagüe del tanque hacia el retrete para la descarga de los desechos; dichas segundas barras huecas 63 detienen el asiento 33 o la tapa 32 o ambos, frenando su caída y haciéndola lenta, venciendo la fuerza el freno hidráulico 57 y del elemento de resorte 65. Cuando la tapa 32 y/o el asiento 33 se levantan, dicho elemento de resorte 65 regresa a dichos brazos de palanca a una posición erguida para recibir nuevamente la tapa y/o el asiento. Dichos elementos de freno 53a y 53b comprenden adicionalmente en una de sus modalidades un elemento de ajuste de la resistencia 66 de dicho elemento de resorte 65 y que consta de una perilla 67 con un husillo 68 que penetra en la oquedad de la carcasa 56 y se rosca hasta el brazo de palanca 60. En los casos donde la tapa 33 y asiento 32 son pesados, la perilla 67 se gira hacia la derecha y se aprieta el elemento de resorte 64, haciendo un ajuste de más presión para que éstos bajen más lento. Y en el caso donde la tapa 33 y asiento 32 son ligeros, la perilla 67 se gira a la izquierda reduciendo presión en el elemento de resorte 65dejando que caigan más rápido.
