OBJETIVO DE LA INVENCIÓN OBJECTIVE OF THE INVENTION

El principal objetivo de la presente invención es el de poder aumentar varias veces la The main objective of the present invention is to be able to increase the

fuerza que aplica el usuario sobre un Destornillador, bien para apretar los Tomillos con force that the user applies on a screwdriver, either to tighten the Thyme with

mucha más fuerza que la que puede ejercer habitualmente, o bien, para desenroscarlos, también con mucha más fuerza que la habitual, lo que es muy práctico en aquellas ocasiones en las que el Tomillo no se deja extraer con facilidad. Al mismo tiempo, este Destornillador-Cono, cuando se hacen Dentadas las Ruedas que lo forman, puede servir, al mismo tiempo, como Engranajes-Cono en serie, que se podrían acoplar a una máquina much more force than you can usually exert, or, to unscrew them, also with much more force than usual, which is very practical on those occasions when Thyme is not easily removed. At the same time, this Screwdriver-Cone, when the Wheels are formed that form it, can serve, at the same time, as Gears-Cone in series, which could be coupled to a machine

Para esto, sólo habría que desenroscar el Soporte ( 1) del Engranaje-Cono que hace las funciones de Mango (2, 3), y, la punta (5) de acoplamiento al Tornillo. De esta manera, quedarían dos Ejes en cada extremo, que se podrían poner en los rodamientos adecuados de la máquina. ANTECEDENTES DE LA INVENCIÓN anyone to increase and maintain strength in any of its pieces. For this, it would only be necessary to unscrew the Support (1) of the Gear-Cone that performs the functions of Handle (2, 3), and, the tip (5) of coupling to the Screw. In this way, there would be two Axes at each end, which could be put in the proper bearings of the machine. BACKGROUND OF THE INVENTION

El principal antecedente de la presente invención se halla en mi Patente n° P200900489, titulada: Coche de vaivén con espirales, en la que se presenta un Engranaje-Cono que es la The main antecedent of the present invention is in my Patent No. P200900489, entitled: Swing car with spirals, in which a Gear-Cone is presented which is the

En la invención de hoy, esta pieza no funciona exactamente igual como cuando la aplicamos en una máquina, aunque, también tiene la misma función que tiene en ella, en el sentido de que el brazo del usuario puede ser la máquina que la utiliza.

The force flows from the Wheel of smaller diameter (15), towards the Wheel of greater diameter (3). In today's invention, this piece does not work exactly the same as when we apply it to a machine, although it also has the same function it has in it, in the sense that the user's arm may be the machine that uses it. Therefore, its main function is to increase the strength in the

DESCRIPCIÓN DE LA INVENCIÓN DESCRIPTION OF THE INVENTION

El Destornillador-Cono con nodos, es una herramienta de presión para apretar y desenroscar tomillos, especialmente útil cuando éstos tornillos se han puesto hace mucho tiempo y se han oxidado, o, se les ha puesto una capa de pintura encima, etc ... de manera que no hay forma de sacarlos de su lugar cuando se los intenta extraer con un Destornillador de los conocidos. El principio de fuerza en el que se apoya esta invención es el' que se obtiene del Engranaje-Cono, que es la pieza descrita en los apartados anteriores, cuya característica principal es la de poder mantener la fuerza que se ha aumentado previamente en la Rueda de menor diámetro de una pieza de Engranaje, cuando se la transmite hacia una Rueda Dentada de mayor diámetro que se haya a distancia de ella, y, unida con ella mediante unas Varillas (13, 14), -figura no 5.. Apoyado en este hecho físico, el Destornillador-Cono no hace otra cosa que aumentar la fuerza que aplica el usuario sobre el Mango en tanto que, en él, se forman Engranajes (3, 15), con una Rueda de mayor diámetro The Screwdriver-Cone with nodes, is a tool of pressure to tighten and unscrew thyme, especially useful when these screws have been put on a long time and have oxidized, or, they have put a layer of paint on top, etc ... so that there is no way to remove them from their place when trying to extract them with a screwdriver known. The principle of force on which this invention is based is that obtained from the Gear-Cone, which is the piece described in the previous sections, whose main characteristic is that of maintaining the force that has been previously increased in the Wheel of smaller diameter of a piece of Gear, when it is transmitted to a Cogwheel of larger diameter that is at a distance from it, and, joined with it by means of Rods (13, 14), -figure no 5. Based on this physical fact, the Screwdriver-Cone does nothing but increase the force that the user applies to the Handle while, in it, Gears (3, 15) are formed, with a larger diameter Wheel

(3), y, otra de menor diámetro (15). A su vez, la Rueda de menor diámetro (15), -que, en este Destornillador-Cono, no es necesariamente una Rueda Dentada, sino, tan sólo un eje, o, una Rueda simple de reducido diámetro-, aumentará la fuerza que ha llegado a la Rueda de mayor diámetro (3) anterior, en tanto que la Rueda (15) está situada en el justo centro del Engranaje que forma con ella.  (3), and, another of smaller diameter (15). In turn, the Wheel of smaller diameter (15), -which, in this Screwdriver-Cone, is not necessarily a Cogwheel, but, just an axle, or, a simple Wheel of reduced diameter-, will increase the force that It has reached the wheel of greater diameter (3) above, while the Wheel (15) is located in the right center of the Gear that forms with it.


El Engranaje-Cono que se forma a continuación con la Rueda (15), unas Varillas (2) que forman el Cono propiamente dicho, y, la Rueda siguiente (3) de mayor diámetro, -figuras no 1-4-, se encargará de mantener esa fuerza aumentada, y, de transmitirla hacia la siguiente Rueda (3), con lo cual, en el segundo Engranaje-Cono puesto en serie, esa fuerza aumentada que ha llegado allí, se volverá a aumentar cuando pase desde la Rueda (3), hasta la si-guiente Rueda {i5) de menor diámetro que se halla situada en su centro. En ésta, si la proporción de sus diámetros es la misma que la del Engranaje anterior, la fuerza aumentará tres veces si es que el diámetro de la Rueda mayor (3) es tres veces el de su Rueda menor ( 15), con lo cual, si antes había aumentado tres veces, ahora, volverá a aumentar otras tres veces más, con lo que tendríamos una fuerza del brazo del usuario que habrá aumentado seis veces cuando sólo hemos puesto dos Engranajes-Cono. Si ponemos un tercero, y, un cuarto Engranaje-Cono, -tal como sucede como cuando le añadimos el Alargador que se observa en la figura n° 2, que se acopla al Destornillador-Cono que acabo de describir, entonces, la fuerza podrá aumentar otras seis veces más, lo que hace un total de doce veces. (Con esta fuerza es más que probable que se pueda abordar con esperanzas de éxito la extracción del Tornillo que se ponía muy difícil). Obviamente, esto formaría un

The Gear-Cone that is then formed with the Wheel (15), Rods (2) that form the Cone itself, and, the next Wheel (3) of greater diameter, -figures no 1-4-, will be in charge of maintaining that increased force, and, of transmitting it to the next Wheel (3), whereby, in the second Gear-Cone put in series, that increased force that has arrived there, will be increased again when it passes from the Wheel ( 3), to the next Wheel {i5) of smaller diameter that is located in its center. In this, if the proportion of its diameters is the same as that of the previous Gear, the force will increase three times if the diameter of the larger Wheel (3) is three times that of its smaller Wheel (15), whereby , if before it had increased three times, now, it will increase again three more times, with which we would have a force of the user's arm that will have increased six times when we have only put two Gear-Cone. If we put a third, and, a fourth Gear-Cone, -as it happens as when we add the Extender that is observed in figure 2, which is attached to the Screwdriver-Cone that I have just described, then, the force can increase another six times more, which makes a total of twelve times. (With this force it is more than likely that the extraction of the Screw that was very difficult can be approached with hopes of success). Obviously, this would form a

Destornillador-Cono demasiado largo, pero, como es desmontable, esto no presentaría grandes problemas. Por otro lado, la posibilidad de añadir Nodos Discontinuos (1'3) a las Varillas (14) de los Conos, permite aumentar aún más la fuerza de origen, en tanto que la fuerza fluye como una Corriente Eléctrica a través del material del Destornillador-Cono, -lo Screwdriver-Cone too long, but, as it is removable, this would not present major problems. On the other hand, the possibility of adding Discontinuous Nodes (1'3) to the Rods (14) of the Cones, allows to increase even more the force of origin, while the force flows like an Electric Current through the material of the Screwdriver -Cono, -lo

cual es lo que permite que suceda lo que acabo de explicar cuando aumenta la fuerza en los Engranajes-Cono-, y, en tanto que fluye de esa manera, cuanto más masivo sea el material que lo forma, esa fuerza va a aumentar en consecuencia o en proporción. De ahí que este sea el sentido principal de la existencia de los Nodos Discontinuos (13) que se ponen en las Varillas (14) del Destornillador-Cono con nodos de la figura n° 5. which is what allows what I just explained to happen when the force in the Gears-Cone increases, and, as it flows that way, the more massive the material that forms it, that force will increase accordingly or in proportion. Hence, this is the main meaning of the existence of the Discontinuous Nodes (13) that are placed on the Rods (14) of the Screwdriver-Cone with nodes of Figure 5.
