En las manecillas de control de funcionamiento para pulverizadores que se conocen en la actualidad, se dispone de una válvula interna cerrada mediante un elemento desplazable cuyas posiciones quedan determinadas, respectivamente, por la acción manual de desplazamiento de dicho vástago y por un resorte antagonista que permite la recuperación de la posición de cierre.In operation control hands for sprayers that are known today, an internal valve closed by a movable element whose positions are determined, respectively, by the action manual displacement of said rod and by a spring antagonist that allows the recovery of the position of closing.

Dadas sus características funcionales, las manecillas de control actualmente conocidas tienen una complicación sensiblemente elevada, puesto que requieren, aparte de los elementos estructurales y de cierre del paso interno para el líquido, de un resorte de recuperación de la posición. Ello complica relativamente tanto la construcción como el montaje y el mantenimiento de la manecilla.Given their functional characteristics, the currently known control hands have a complication noticeably high, since they require, apart from structural and closing elements of the internal passage for the liquid, from a position recovery spring. It relatively complicates both construction and assembly and the hand maintenance.

El objetivo de la presente invención es el de conseguir una manecilla de gran eficacia funcional, larga vida útil sin necesidad de mantenimiento y de construcción simplificada y, por lo tanto, económica. Las pruebas y experimentaciones realizadas por los inventores han conducido a la realización de una manecilla de control para pulverizadores de líquido que permite reducir sensiblemente el número de piezas de que consiste la manecilla eliminando el resorte antagonista tradicionalmente utilizado y haciendo muy sencilla, tanto la fabricación de los elementos de la manecilla como su montaje, lo que redunda en una sensible ventaja económica. Además, dada su realización constructiva, la manecilla objeto de la presente invención aporta una larga vida útil.The objective of the present invention is to get a hand of great functional efficiency, long service life maintenance free and simplified construction and, Therefore, economical. The tests and experiments performed by the inventors have led to the realization of a hand of control for liquid sprayers that allows to reduce noticeably the number of pieces that the hand consists of eliminating the traditionally used antagonist spring and making very simple, both manufacturing the elements of the hand as its assembly, which results in a sensible advantage economical In addition, given its constructive realization, the hand object of the present invention provides a long service life.

De modo esencial, de acuerdo con la presente invención, la manecilla de control para pulverizadores de líquidos está realizada básicamente mediante tres piezas, una de ellas comporta el cuerpo y palanca o manecilla propiamente dicha, la segunda es un filtro y la tercera un vástago o eje de salida del líquido que se incorporan a dicho cuerpo, con la característica de que la palanca o manecilla propiamente dicha y el cuerpo de la misma están constituidos por inyección en un material sintético, preferentemente el mismo material si bien, se podría proceder también a la realización en dos materiales distintos, de manera que la parte de la manecilla propiamente dicha tiene una sensible elasticidad que le permite recuperar su posición después de su accionamiento manual.

Using this feature, the hand of  control can work without the need for antagonist springs and, In addition, the assembly of the hand assembly is extraordinarily simple, since it simply involves the threaded coupling of the output shaft or front axle and the pressure coupling of the filter carrier part.

Para su mejor comprensión se adjuntan, a título de ejemplo no limitativo, unos dibujos explicativos de una realización preferente de la presente invención.For your better understanding they are attached, by title non-limiting example, some explanatory drawings of a preferred embodiment of the present invention.

La figura 1 muestra una vista en perspectiva de una manecilla de accionamiento de pulverizadores de acuerdo con la presente invención con el tubo de salida y tobera de pulverización.Figure 1 shows a perspective view of a spray actuator hand according to the present invention with the outlet tube and nozzle of spray.

La figura 2 muestra una vista en alzado lateral de la manecilla objeto de la invención.Figure 2 shows a side elevation view of the hand object of the invention.

Las figuras 3 y 4 muestran sendas secciones de la manecilla en reposo y en situación de accionamiento para la pulverización.Figures 3 and 4 show sections of the hand at rest and in driving situation for the spray.

La figura 5 muestra una vista en perspectiva con las piezas de la manecilla desmontadas.Figure 5 shows a perspective view with  disassembled hand parts.

Tal como se aprecia en las figuras, la manecilla objeto de la presente invención comprende un conjunto (1) de control de paso del líquido a presión y de sujeción que comporta esencialmente un mango (2) y una palanca o manecilla articulada propiamente dicha (3), conectándose dicha manecilla por un extremo al conducto flexible (4) que comunica con el depósito de líquido a presión y por el otro con el tubo rígido (5) que presenta en su extremo la tobera de pulverización (6).As seen in the figures, the hand  object of the present invention comprises a set (1) of control of passage of the pressurized and clamping liquid that involves essentially a handle (2) and a lever or articulated hand proper (3), said hand connecting at one end to the flexible conduit (4) that communicates with the liquid reservoir a pressure and on the other with the rigid tube (5) that presents in its end the spray nozzle (6).

Tal como se aprecia en la figura 5, el conjunto (1) recibe un vástago o eje frontal (7) de conexión al tubo (5) y al cuerpo (2) y un filtro (8) que se incorpora a presión por el otro extremo.As seen in Figure 5, the set (1) receives a rod or front axle (7) connecting to the tube (5) and to the body (2) and a filter (8) that is incorporated under pressure by the other extreme

El cuerpo (1) de la manecilla presenta el mango de sujeción (2) y un elemento tubular (9) en cuyo interior queda alojado por un lado el filtro (8) acoplado al racor de conexión con el tubo (4) y por el otro, el extremo del elemento tubular o vástago (7) que controla el paso de líquido. Para efectuar dicho control, el vástago (7) está encajado en una zona cilíndrica (10) del cuerpo tubular (9) con diámetro más reducido y presenta dos juntas tóricas (11) y (12). En la posición de reposo que se muestra en la figura 3, el anillo tórico (12) cierra el paso del líquido, mientras que en la posición activa representada en la figura 4, al salir el anillo tórico (12) de su coincidencia con la zona cilíndrica (10) permite el paso del líquido hacia el tubo (5) y boquilla (6).The body (1) of the hand has the handle clamping (2) and a tubular element (9) whose interior is housed on one side the filter (8) coupled to the connection fitting with the tube (4) and on the other, the end of the tubular element or stem (7) that controls the passage of liquid. To effect said control, the rod (7) is embedded in a cylindrical zone (10) of the tubular body (9) with smaller diameter and has two O-rings (11) and (12). In the resting position that shown in figure 3, the O-ring (12) closes the passage of the liquid, while in the active position represented in the Figure 4, when leaving the O-ring (12) of its coincidence with the cylindrical zone (10) allows the passage of liquid into the tube (5) and nozzle (6).

Dicho vástago (7), en la parte que queda dispuesta en el interior del elemento tubular (9), presenta un alojamiento en el que queda dispuesto un terminal del filtro (8), en forma de varilla (13) con cabeza de retención, permitiendo su acoplamiento a presión desde el extremo posterior del cuerpo (1).Said rod (7), in the remaining part arranged inside the tubular element (9), it has a housing in which a filter terminal (8) is arranged, in the form of a rod (13) with retention head, allowing its snap coupling from the rear end of the body (one).

Una característica esencial de la manecilla objeto de la presente invención, consiste en que la posición de cierre representada en la figura 3 queda determinada por la posición estable del conjunto formado por la manecilla (3), cuerpo (1) y zona curvada de conexión (14), de manera que la posición activa representada en la figura 4 se consigue venciendo manualmente la elasticidad de dicha parte curvada (14) permitiendo el paso del líquido. Al liberar manualmente el elemento de manecilla (3), la elasticidad de la parte de conexión (14) devolverá la manecilla a la posición de reposo representada en la figura 3 en la que se produce el cierre del paso del líquido. Para facilitar dicha vuelta, la parte curvada (14) presenta una zona de contacto (en este caso, un saliente) con una zona específica del vástago (7) tal como se observa en la figura 3.An essential feature of the hand object of the present invention, is that the position of closure represented in figure 3 is determined by the stable position of the assembly formed by the hand (3), body (1) and curved connection area (14), so that the position active represented in figure 4 is achieved by winning manually the elasticity of said curved part (14) allowing the passage of the liquid. By manually releasing the item from hand (3), the elasticity of the connecting part (14) return the hand to the resting position represented in the Figure 3 in which the closing of the liquid passage occurs. For facilitating said turn, the curved part (14) has an area of contact (in this case, a projection) with a specific area of the stem (7) as seen in figure 3.

El desplazamiento del eje o vástago (7) es producido, por lo tanto, por la acción del puente transversal (15) de la parte de conexión curvada (14) mediante alojamientos (16) que actúan sobre topes (17) de dicho vástago o eje (7). La posición relativa de dichos alojamientos (16) y topes (17) se puede apreciar observando las figuras 3 y 4.The displacement of the shaft or rod (7) is produced, therefore, by the action of the transverse bridge (15) of the curved connection part (14) by housings (16) that they act on stops (17) of said rod or shaft (7). The position relative of said housings (16) and stops (17) can be seen  looking at figures 3 and 4.

Si bien la presente invención ha sido representada a título de ejemplo en los dibujos adjuntos y explicada en la correspondiente descripción, se comprenderá que se pueden introducir múltiples modificaciones en aspectos de la misma sin salir del ámbito de la presente invención, tal como se define en las reivindicaciones adjuntas.While the present invention has been represented by way of example in the attached drawings and explained in the corresponding description, it will be understood that they can introduce multiple modifications in aspects of it without leaving the scope of the present invention, as defined in the appended claims.
