En los orificios 7 y 9 es donde se instala el mecanismo de funcionamiento, cuyos componentes están fabricados normalmente con plástico rígido.The number 5 in Figure 1 indicates, schematically, a toilet cistern formed by a standard threaded hose (not shown) for connection to the water supply pipe, and a standard buoy (not shown) to control the entry of water. Normally cistern 5 is at air, that is, that is not embedded in the wall, can be made ceramic or plastic and is formed by a rear wall 6 with a hole 7 and a removable cover 8 that also has a hole 9. In holes 7 and 9, the installation mechanism is installed. operation, whose components are normally manufactured with rigid plastic

El mecanismo 10 está formado por una pieza de descarga 11 que tiene un elemento exterior roscado 12, un saliente plano 13 y un elemento superior de mayor diámetro 14. El elemento roscado 12 va dentro del orificio 7 mediante la interposición de un obturador 15, y va unido a la pared trasera 6 de la cisterna 5 por medio de un collar roscado 16; y el elemento 14 va conectado al saliente 13 por cuatro segmentos axiales 17 que forman cuatro aberturas 18 que permiten el paso del agua desde la cisterna 5 al elemento roscado 12.The mechanism 10 is formed by a piece of discharge 11 having a threaded outer element 12, a projection plane 13 and an upper element of larger diameter 14. The element threaded 12 goes inside hole 7 by interposing a shutter 15, and is attached to the rear wall 6 of the tank 5 by middle of a threaded collar 16; and element 14 is connected to projection 13 by four axial segments 17 forming four openings 18 that allow the passage of water from cistern 5 to threaded element 12.

El elemento 14 incluye una ranura en forma de L 19 (Figura 1), que se une a bayoneta a un cuerpo fijo 21 por medio de un pasador radial 20, formando la parte fija del mecanismo de funcionamiento 10. El cuerpo 21 tiene la forma de un cilindro hueco y alberga un tubo de descarga 22 de deslizamiento vertical que incorpora un anillo elástico 25 en el extremo inferior para el cierre de la válvula de descarga (que no se muestra).Element 14 includes an L-shaped groove 19 (Figure 1), which attaches bayonet to a fixed body 21 by means of a radial pin 20, forming the fixed part of the mechanism of operation 10. The body 21 has the shape of a hollow cylinder and houses a vertical slide 22 discharge tube that incorporates an elastic ring 25 at the lower end for the discharge valve closure (not shown).

Cuando sube solo, el tubo 22 produce la descarga parcial del agua de la cisterna 5, como se describe en la solicitud de patente presentada simultáneamente por el Solicitante de la presente y titulada "Mecanismo para el funcionamiento de la válvula de descarga de una cisterna de sanitario". Como también se describe en la solicitud referida, el cuerpo 21 aloja un manguito de deslizamiento vertical 23 para el accionamiento de la descarga total del agua de la cisterna 5, y que es concéntrico al tubo 22 y tira de él cuando se mueve hacia arriba.When it goes up alone, the tube 22 produces the discharge Partial water tank 5, as described in the application of patent filed simultaneously by the Applicant of the present and entitled "Mechanism for the operation of the discharge valve of a toilet cistern. "As well as described in the aforementioned application, the body 21 houses a sleeve vertical slide 23 for the discharge drive total water from cistern 5, and that is concentric to tube 22 and pull it when it moves up.

El mecanismo de funcionamiento comprende también un alojamiento 24 que alberga dos botones de accionamiento 26 y 27 que hacen funcionar respectivamente la descarga parcial y total del agua de la cisterna. El alojamiento 24 está formado por un elemento roscado exteriormente 28, un saliente 29 y un elemento superior 30 que guía los botones de accionamiento 26 y 27 y termina con un reborde 31. La parte roscada 28 del alojamiento 24 se une a una parte roscada 33 (Figuras 2 y 3) de un manguito 32, que está formado por una serie de nervios axiales 34 (Figura 4), dos acanaladuras tangenciales opuestas 36 y un elemento en forma de embudo 37 que se fija a la superficie de la base de la tapa 8. Insertando el alojamiento 24 en el orificio 9 (Figura 1) de la tapa 8, y roscando la parte roscada 28 dentro de la parte roscada 33 del manguito 32, la tapa 8 queda unida, pero fácilmente desmontable, entre el saliente 29 del alojamiento 24 y el borde del elemento con forma de embudo 37.The operating mechanism also includes a housing 24 housing two drive buttons 26 and 27 which operate the partial and total discharge of the cistern water. The housing 24 is formed by an element externally threaded 28, a projection 29 and an upper element 30 which guides the drive buttons 26 and 27 and ends with a flange 31. The threaded part 28 of the housing 24 joins a threaded part 33 (Figures 2 and 3) of a sleeve 32, which is formed by a series of axial nerves 34 (Figure 4), two grooves opposite tangentials 36 and a funnel-shaped element 37 that is fixed to the surface of the base of the lid 8. Inserting the housing 24 in hole 9 (Figure 1) of cover 8, and threading the threaded part 28 inside the threaded part 33 of the sleeve 32, the lid 8 is attached, but easily removable, between the protrusion 29 of the housing 24 and the edge of the shaped element funnel 37.

El mecanismo de funcionamiento 10 también contiene un soporte 38 que, como se verá más adelante, está conectado al cuerpo fijo 21 y está formado por un anillo superior o elemento anular 39 en el que se inserta el manguito 32 con una ligera fricción con los nervios 34; y la superficie interna del anillo 39 comprende dos nervios axiales opuestos 41 (Figura 5) que van unidos entre dos pares de nervios 34 en el manguito 32 para limitar la rotación del manguito 32 dentro de anillo 39.The operating mechanism 10 also it contains a support 38 which, as will be seen later, is connected to the fixed body 21 and is formed by an upper ring or annular element 39 in which the sleeve 32 is inserted with a slight friction with nerves 34; and the inner surface of the ring 39 comprises two opposite axial nerves 41 (Figure 5) that they are joined between two pairs of ribs 34 in sleeve 32 to limit the rotation of the sleeve 32 within ring 39.

El soporte 38 lleva una placa oblonga transversal 42 conectada al anillo 39 por dos segmentos curvos de sección horizontal 43 que se alternan con dos paredes planas opuestas entre sí 46. Cada pared 46 consta de una parte curva que forma una guía transversal 47 (Figura 3); las dos guías 47 son paralelas, especulares y de sección semicircular; y los dos nervios 41 están ligeramente compensados con respecto al eje longitudinal de las guías 47, y contribuyen a fijar la posición del manguito 32 (Figura 4) con las dos acanaladuras 36 que están frente a las dos guías 47.The support 38 carries a transverse oblong plate 42 connected to ring 39 by two curved section segments horizontal 43 that alternate with two opposite flat walls between yes 46. Each wall 46 consists of a curved part that forms a guide transversal 47 (Figure 3); the two guides 47 are parallel, specular and semicircular section; and the two nerves 41 are slightly compensated with respect to the longitudinal axis of the guides 47, and contribute to fix the position of the sleeve 32 (Figure 4) with the two grooves 36 facing the two guides 47

El mecanismo de funcionamiento 10 lleva unos elementos regulables que, a su vez, constan de una pieza de conexión 48 que tiene dos brazos paralelos 49, que van dentro de las dos guías 47 del soporte 38 y se deslizan transversalmente con respecto al soporte 38. La pieza 48 contiene también una pieza transversal 51 que conecta los dos brazos 49 y se manejan manualmente para mover la pieza 48 y, por tanto, se encuentran fuera del soporte 38.The operating mechanism 10 carries about adjustable elements that, in turn, consist of a connecting piece 48 which has two parallel arms 49, which go inside the two guides 47 of support 38 and slide transversely with respect to to support 38. Piece 48 also contains a cross piece 51 which connects the two arms 49 and are manually operated to move the piece 48 and, therefore, are outside the support 38.

Los brazos 49 son flexibles, reposan normalmente en posición radial a las guías 47 y cada uno tiene un elemento 52 de un grosor que encaja completamente en la guía correspondiente 47. Otra parte 53 de cada brazo 49, adyacente a la pieza transversal 51, tiene un grosor mayor y se proyecta hacia dentro del anillo 39; y la pieza 48 consta de dos pares de apéndices elásticos 54 y 56 en los extremos de los brazos 49 y en la pieza transversal 51, respectivamente.The arms 49 are flexible, they rest normally radially to guides 47 and each has an element 52 of a thickness that fits completely into the corresponding guide 47. Another part 53 of each arm 49, adjacent to the crosspiece 51, it is thicker and projects into ring 39; and the piece 48 consists of two pairs of elastic appendages 54 and 56 in the ends of the arms 49 and in the crosspiece 51, respectively.

Para liberar la tapa 8 (Figuras 1 y 2) de la cisterna 5, de un lado, el alojamiento 24 de los botones de accionamiento 26 y 27 se inserta en un orificio interior 9 de la tapa 8 y la parte roscada 28 se enrosca dentro de la parte roscada 33 del manguito 32, de forma que la tapa 8 queda fijada entre el reborde 31 del alojamiento 24 y el borde del elemento en forma de embudo 37.To release cover 8 (Figures 1 and 2) of the cistern 5, on one side, the housing 24 of the buttons drive 26 and 27 is inserted into an inner hole 9 of the cover 8 and the threaded part 28 is screwed into the threaded part 33 of the sleeve 32, so that the cover 8 is fixed between the flange 31 of the housing 24 and the edge of the shaped element funnel 37.

Del otro lado, la pieza 48 (Figura 4) va colocada, sin necesidad de herramientas, con las partes 52 de los brazos 49 dentro de las guías 47, de modo que los apéndices 54 de los brazos 49 conectan respectivamente con los extremos de las guías 47, como se muestra con las líneas de puntos de la Figura 4; y el manguito 32, conjuntamente con la tapa 8 y el alojamiento 24, se meten dentro del anillo 39 del soporte 38. Como las partes 52 de los brazos 49 no encajan con las acanaladuras 36, la tapa 8 descansa simplemente sobre la cisterna 5, junto con el manguito 32 y el alojamiento 24.On the other side, piece 48 (Figure 4) goes placed, without tools, with parts 52 of the arms 49 within guides 47, so that appendices 54 of the arms 49 connect respectively with the ends of the guides 47, as shown with the dotted lines of Figure 4; and the sleeve 32, together with cover 8 and housing 24, are they fit into ring 39 of bracket 38. As parts 52 of the arms 49 do not fit with grooves 36, cover 8 rests simply on tank 5, together with sleeve 32 and the accommodation 24.

A la inversa, para asegurar la tapa 8 a la cisterna 5, se mete el manguito 32 en el anillo 39 de modo que las acanaladuras 36 coincidan con las guías 47; por medio de la pieza transversal 51, la pieza 48 es desplazada transversalmente a la posición de la Figura 4 en la que los apéndices 56 se fijan a los extremos respectivos de las paredes 46; las partes 53 de los brazos 49 se encuentran ahora en las guías 47 para encajar en las acanaladuras 36 del manguito 32, que quede de esta forma asegurado al soporte 38; la tapa 8 queda unida a la cisterna 5 y el alojamiento 24 queda roscado dentro del manguito 32 para fijar la tapa 8 a la cisterna 5. En este caso, para acceder al interior de la cisterna 5, el alojamiento 24 debe ser, evidentemente, desenroscado y retirado.Conversely, to secure cover 8 to the cistern 5, the sleeve 32 is inserted into the ring 39 so that the grooves 36 coincide with guides 47; through the piece transverse 51, part 48 is displaced transversely to the position of Figure 4 in which the appendices 56 are fixed to the respective ends of the walls 46; the arm parts 53 49 are now in guides 47 to fit in grooves 36 of sleeve 32, which is thus secured to support 38; the lid 8 is attached to the tank 5 and the housing 24 is threaded into sleeve 32 to fix the cover 8 to cistern 5. In this case, to access the interior of the cistern 5, the housing 24 must obviously be unscrewed and retired.

El sistema de montaje también contempla la adaptación del mecanismo de funcionamiento 10 a cisternas 5 de diferentes alturas, para lo cual, el cuerpo fijo 21 se conecta al soporte 38 por medio de un ajuste que consta de dos apoyos opuestos entre sí integrados en el cuerpo 21, dos barras dentadas 58 integradas en el soporte 38 y dos pernos 59 para fijar las barras 58 a los apoyos 57.The mounting system also includes the adaptation of the operating mechanism 10 to tanks 5 of different heights, for which, the fixed body 21 is connected to the support 38 by means of an adjustment consisting of two opposite supports integrated into the body 21, two toothed bars 58 integrated in the support 38 and two bolts 59 to fix the bars 58 to supports 57.
