Description
DESTORNILLADOR MULTIPLE MULTIPLE SCREWDRIVER
D E S C R I P C I O N OBJETO DE LA INVENCION D E S C R I P C I O N OBJECT OF THE INVENTION
La presente invención se refiere a un destornillador, concretamente a un destornillador múltiple, es decir, a un destornillador capacitado para actuar indistintamente sobre tornillos con diferentes cabezas, adecuándose en cualquier caso a las exigencias especificas y concretas del tornillo, y todo ello con una estructuración sumamente simple y consecuentemente económica. The present invention relates to a screwdriver, specifically to a multiple screwdriver, that is, to a screwdriver capable of acting interchangeably on screws with different heads, adapting in any case to the specific and specific requirements of the screw, and all with a structuring extremely simple and consequently economical.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Independientemente de que existen tornillos con diferente tipo de cabeza en lo que a sus medios de accionamiento se refiere, fundamentalmente tornillos provistos de una ranura diametral y tornillos provistos de un vaciado axial con prolongaciones radiales, comunmente denominados de "estrella", existen además diferencias dimensionales importantes en tales medios, tanto en lo que se refiere a su anchura como a su profundidad, en función del tamaño del tornillo y del esfuerzo que se haya previsto sea necesario realizar durante el apriete.
Esto trae consigo la necesidad de disponer, para cada tipo de tornillo, es decir, para los tornillos ranurados y para los tornillos de estrella, de sendos juegos de d e s t o r n i l l a d o r e s que, siendo básicamente idénticos, se diferencian exclusivamente en su tamaño, especialmente en el tamaño de su extremidad activa, al objeto de adecuarla a la ranura o la estrella del tornillo. Generalmente existe un destornillador especifico para cada tipo y tamaño de tornillo, a base de una varilla rematada por uno de sus extremos en un mango o empuñadura y con su extremidad libre conformada de acuerdo con las exigencias del tipo de tornillo a que se destina. Regardless of whether there are screws with a different type of head as far as their drive means are concerned, mainly screws provided with a diametral groove and screws provided with an axial recess with radial extensions, commonly referred to as "star", there are also dimensional differences important in such means, both as regards its width and its depth, depending on the size of the screw and the effort that has been foreseen, it is necessary to perform it during tightening. This brings with it the need to provide, for each type of screw, that is, for slotted screws and for star screws, of two sets of screwdrivers that, being basically identical, differ exclusively in their size, especially in size of its active limb, in order to adapt it to the groove or screw star. There is usually a specific screwdriver for each type and size of screw, based on a rod topped by one of its ends in a handle or handle and with its free end shaped according to the requirements of the type of screw to which it is intended.
Se deduce de lo anteriormente expuesto que dada la gran diversidad de tornillos existente en el mercado, existe también la necesidad de disponer de una gran diversidad de destornilladores. It follows from the foregoing that given the great diversity of screws in the market, there is also a need for a wide variety of screwdrivers.
Tratando de obviar este problema son conocidos también destornilladores múltiples en los que participa un mango único y un juego de varillas de diferentes tamaños y configuraciones, acoplables selectivamente al citado mango.
Sin embargo esta solución presenta una proble-. mática con una doble vertiente, por un lado el sistema resulta estructuralmente complejo y consecuentemente caro, y por otro lado la maniobra de sustitución del tipo de destornillador propiamente dicho resulta lenta y relativamente complicada. Trying to avoid this problem are also known multiple screwdrivers in which a single handle and a set of rods of different sizes and configurations, selectively attachable to the aforementioned handle. However, this solution presents a problem. With a double slope, on the one hand the system is structurally complex and consequently expensive, and on the other hand the replacement operation of the type of screwdriver itself is slow and relatively complicated.
DESCRIPCION DE LA INVENCION El destornillador que la invención propone ha sido concebido y estructurado en orden a resolver de forma plenamente satisfactoria la problemática anteriormente expuesta, constituyendo un instrumento estructuralmente muy simple, consecuentemente de bajo costo, que ofrece además una gran facilidad de manipulación o utilización. DESCRIPTION OF THE INVENTION The screwdriver proposed by the invention has been conceived and structured in order to solve in a fully satisfactory manner the above-mentioned problem, constituting a structurally very simple instrument, consequently of low cost, which also offers a great ease of handling or use. .
Para ello y de forma más concreta, el destornillador que se preconiza está constituido mediante un cuerpo monopieza, metálico, aplanado, con una configuración estrellada, provisto de una pluralidad de cortos brazos radiales, en número variable, mayor cuanto lo sea la capacidad operativa prevista para el destornillador, rematándose cada uno de estos brazos radiales en un cabezal operativo o destornillador propiamente dicho, de manera que todos los brazos emergentes del citado cuerpo son distintos entre si, en función de los diferentes tamaños de tornillo a que se destina,
y opcionalmente también en función de diferentes tipos de tornillo, ranurado o estrellado. To do this and more specifically, the screwdriver that is recommended is constituted by a single-piece body, metallic, flattened, with a starry configuration, provided with a plurality of short radial arms, in variable number, greater as the expected operational capacity is for the screwdriver, finishing each of these radial arms in an operating head or screwdriver itself, so that all the emerging arms of said body are different from each other, depending on the different screw sizes to which it is intended, and optionally also depending on different types of screw, grooved or crashed.
Se deduce de lo anteriormente expuesto que el citado cuerpo aplanado actúa como mango o asidero del destornillador, resultando operativo en cada caso aquel de sus brazos radiales que se adecúe más al tipo de tornillo a manipular. Como complemento de la estructura descrita y de acuerdo con otra de las carácteristicas de la invención, se ha previsto que el citado cuerpo plano esté dotado de un orificio central que permite el acoplamiento eventual al mismo de cualquier objeto alargado, en funciones de palanca, para potenciar el esfuerzo aplicado al destornillador durante la maniobra de atornillamiento o desatornillamiento. It follows from the foregoing that the aforementioned flattened body acts as a handle or handle of the screwdriver, being in each case operative that of its radial arms that best suits the type of screw to be handled. As a complement to the structure described and according to another of the characteristics of the invention, it is provided that said flat body is provided with a central hole that allows the eventual coupling thereto of any elongated object, in lever functions, for enhance the effort applied to the screwdriver during the screwing or unscrewing operation.

REALIZACION PREFERENTE DE LA INVENCION Figure 3.- Shows a view similar to that of Figure 1, but corresponding to a screwdriver provided for star screws. PREFERRED EMBODIMENT OF THE INVENTION
A la vista de estas figuras puede observarse cómo el destornillador múltiple que se preconiza está constituido por un cuerpo monopieza (1), aplanado, básicamente discoidal, pero provisto de una pluralidad de brazos radiales (2), de escasa longitud, que se rematan en cabezales operativos (3) que, de acuerdo con el ejemplo de realización práctico representado en la figura 1, se asemejan a la extremidad operativa de un destornillador clásico destinado a tornillos ranurados, correspondiendo los diferentes brazos radiales ( 2) a diferentes y respectivas medidas de tornillo, desde un brazo ( 2 ' ) de dimensiones minimas para tornillos
muy pequeños, hasta un brazo ( 2 " ) de dimensiones máximas, y destinado al mayor tamaño de tornillos para los que se ha previsto el destornillador. No obstante y tal como se ha representado en la figura 3, el cuerpo plano (1) puede presentar sus brazos ( 2 ) rematados en cabezales (3') estrellados, para actuación del destornillador sobre tornillos de estrella, existiendo igualmente diferentes medidas en los diversos brazos emergentes del cuerpo (1), exactamente igual que en el caso anterior como se desprende de la simple observación de las figuras 1 y 3, para adecuarse a diferentes tamaños de tornillos. Es evidente que mediante la adecuada modificación en el cabezal operativo (3) de los diferentes brazos (2) del destornillador, éste seria aplicable igualmente a tornillos tipo alien o de cualquier otro tipo. In view of these figures it can be seen how the multiple screwdriver that is recommended is constituted by a single-piece body (1), flattened, basically discoidal, but provided with a plurality of radial arms (2), of short length, which are finished in operating heads (3) which, according to the example of practical embodiment shown in Figure 1, resemble the operating end of a classic screwdriver intended for slotted screws, the different radial arms (2) corresponding to different and respective measures of screw, from an arm (2 ') of minimum dimensions for screws very small, up to an arm (2 ") of maximum dimensions, and intended for the larger size of screws for which the screwdriver is intended. However, and as shown in Figure 3, the flat body (1) can present their arms (2) topped in heads (3 ') crashed, for screwdriver action on star screws, there are also different measures in the various emerging arms of the body (1), exactly the same as in the previous case as it appears from the simple observation of figures 1 and 3., to adapt to different sizes of screws.It is evident that by proper modification in the operating head (3) of the different arms (2) of the screwdriver, this would also be applicable to alien type screws or of any other type.
De análoga manera existe también la posibilidad de mezclar diferentes prestaciones en cuanto al tipo de tornillos se refiere en el seno de un mismo cuerpo aplanado (1), de manera que dicho cuerpo esté dotado por ejemplo de nueve brazos, incorporando tres de ellos diferentes cabezales operativos sobre tornillos ranurados, otros tres sobre tornillos de estrella y otros tres sobre tornillos alien, y pudiéndose realizar
cualquier tipo de combinaciones al respecto, sin que ello afecte en absoluto a la esencia de la invención. Similarly, there is also the possibility of mixing different features in terms of the type of screws referred to within the same flattened body (1), so that said body is provided, for example, with nine arms, incorporating three of them different heads operating on slotted screws, another three on star screws and another three on alien screws, and being able to perform any type of combinations in this regard, without affecting the essence of the invention at all.
El número de brazos radiales (2) emergentes del cuerpo ( 1 ) será también variable en función del nivel de prestaciones previsto para el destornillador, sin que tampoco ello afecte en absoluto a la esencia de la invención. De análoga manera los citados brazos radialesThe number of radial arms (2) emerging from the body (1) will also vary depending on the level of performance provided for the screwdriver, without affecting the essence of the invention at all. Similarly, the aforementioned radial arms
(2) podrán emerger con carácter monopieza del cuerpo aplanado (1) o constituir elementos inicialmente independientes, convenientemente fijados al cuerpo (1), mediante soldadura o por cualquier otro medio, sin que tampoco ello afecte a la esencia de la invención. (2) they may emerge as a single piece from the flattened body (1) or constitute initially independent elements, conveniently fixed to the body (1), by welding or by any other means, without affecting the essence of the invention.
En cualquier caso, el cuerpo aplanado (1) estará dotado de un orificio central (4) de reducido diámetro, que permita el paso a través del mismo de cualquier objeto alargado, como por ejemplo una varilla, que pueda actuar como palanca para potenciar el esfuerzo mecánico transmitido al destornillador durante las maniobras de aflojamiento o apriete realizadas con el mismo. In any case, the flattened body (1) will be provided with a central hole (4) of small diameter, allowing the passage through it of any elongated object, such as a rod, which can act as a lever to enhance the mechanical effort transmitted to the screwdriver during loosening or tightening maneuvers performed with it.
No se considera .necesario hacer más extensa esta descripción para que cualquier experto en la materia comprenda el alcance de la invención y las
ventajas que de la misma se derivan. It is not considered necessary to make this description more extensive so that any person skilled in the art understands the scope of the invention and the advantages that derive from it.
Los materiales, forma, tamaño y disposición de los elementos serán susceptibles de variación, siempre y cuando ello no suponga una alteración a la esencialidad del invento. The materials, shape, size and arrangement of the elements will be susceptible to variation, as long as this does not imply an alteration to the essentiality of the invention.
Los términos en que se ha descrito esta memoria deberán ser tomados siempre en sentido aplio y no limitativo.
The terms in which this report has been described must always be taken in an aplius and non-limiting sense.
