SECTOR DE LA TÉCNICA SECTOR OF THE TECHNIQUE
El principal campo de aplicación de éste sistema es el de las herramientas manuales. The main field of application of this system is that of hand tools.
El objeto de esta patente de invención es el tíe conseguir un sistema de sujeción para tomillos y tuercas utilizadle por las llaves tijas o combinadas, que sea reversible y que además no suponga un incremento económico sustancial en el precio de las llaves combinada The object of this invention patent is to obtain a fastening system for thyme and nuts used by the scissor or combination wrenches, which is reversible and also does not imply a substantial economic increase in the price of the combined keys
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Las llaves combinadas con carraca son herramientas que tienen un mango con dos extremos uno de ellos, tiene una llave fija con una medida determinada de apriete para tornillos y tuercas, y el otro extremo, tiene un sistema de ilave de carraca que pueda ser articulado y tiene un hueco abierto interior o aro de apriete, por el que se introduce la cabeza de un tornillo o tuerca, además según sea el iado por el que se introduce la cabeza del tornillo éste extremo sirve para apretar o para aflojar, tornillos y tuercas de la misma medida que el extremo de llave fija, siendo asi reversible. The keys combined with ratchet are tools that have a handle with two ends one of them, has a fixed wrench with a certain tightening measure for screws and nuts, and the other end, has a ratchet ilave system that can be articulated and It has an internal open hole or tightening ring, through which the head of a screw or nut is introduced, also depending on the connection by which the screw head is introduced, this end is used to tighten or loosen, screws and nuts the same measure as the fixed key end, thus being reversible.
Este sistema de llave de carraca, para llaves combinadas, presenta un pequeño inconveniente, y es que, cuando queremos apretar un tornillo, por ejemplo de llave hexagonal, dicho tomillo tiene un tamaño de cabeza o profundidad de cabeza pequeño, por lo que cuando utilizamos el extremo con carraca de la llave combinada, para no pasamos la cabeza de largo y poder apretar el tornillo, tenemos que sujetar el mango de la llave lo más cerca posible de dicho extrema y ayudamos con el dedo para poder apretar, sin pasarnos de largo, la cabeza del tomillo que pretendemos apretar Además, hay determinados casos en los que el hueco en donde se encuentra el tomillo es de difícil acceso y no cabe la mano  This ratchet wrench system, for combination wrenches, has a small drawback, and when we want to tighten a screw, for example a hexagonal wrench, said thyme has a small head size or depth of head, so when we use the combined ratchet end of the key, so as not to pass the head long and to be able to tighten the screw, we have to hold the handle of the key as close as possible to said end and help with the finger to be able to tighten, without passing by , the head of the thyme that we intend to tighten In addition, there are certain cases in which the hole where the thyme is located is difficult to access and does not fit the hand
Una de las soluciones existentes para este problema es fabricar los tornillos con una arandela fija en la base de la cabeza de ios tornillos, tíe manera que cuando introducimos el aro de apriete con carraca de la llave combinada, éste se encuentra con la arandela y no permite introducirse más abajo de la cabeza o parte de apriete dei tornillo ésta solución, nos limita a la utilización de este tipo de tomillos o tuercas Existe otra solución que se utiliza en el extremo de llave fija que es el utilizado en las llaves Fórrc éste sistema consiste en colocar una chapa metálica en una de les cares del extremo de llave fija de la llave combinada con carraca, de manera que haga de tope en la cara superior de la cabeza de un tornillo e impida que el tomillo se pase de largo de la zona de apriete Este sistema sólo es válida para colocado en el extremo de llave fija, pera no es útil, en eí extremo con carraca de le llave combinada One of the existing solutions for this problem is to manufacture the screws with a fixed washer at the base of the head of the screws, so that when we introduce the tightening ring with ratchet of the combined wrench, it meets the washer and not this solution can be introduced below the head or tightening part of the screw, it limits us to the use of this type of thyme or nut There is another solution that is used at the end of the fixed key that is used in the Fórrc keys. This system consists of placing a metal plate in one of the sides of the fixed key end of the key combined with ratchet, so that it acts as a stop on the upper face of the head of a screw and prevent the thyme from running past the tightening zone This system is only valid for placement at the end of the fixed key, but it is not useful, at the end with a ratchet the combined key
EXPLICACIÓN DE LA INVENCIÓN EXPLANATION OF THE INVENTION
Para solucionar este problema, se ha ideado por parte del inventor un sistema que consiste en un gorro reversible, que cuando se introducela cabeza de un tomillo o una tuerca por el hueco interior abierto del extremo con carraca y/o de llave fija de la llave combinada, éste gorro hace de tope o arandela, e impide que se pase de largo dicha cabeza y quede colocada dentro del hueco de apriete, sin necesidad de utilizar tomillos con arandelas o un dedo. To solve this problem, a system consisting of a reversible cap has been devised by the inventor, which when a thyme head or a nut is introduced through the open inner hole of the ratchet end and / or fixed key wrench combined, this cap acts as a stopper or washer, and prevents the head from being passed over and placed inside the tightening hole, without the need to use thymes with washers or a finger.
Este sistema, además, es útil utilizándolo con otra tipo de llaves, por ejemplo, llaves combinadas sin carraca, y en llaves fijas y similares  This system is also useful when used with other types of keys, for example, combination keys without ratchet, and fixed and similar keys
Explicando con mayor detenimiento, el sistema consiste en la utilización de un gorro extraíble y reversible (apretar y aflojar) de manera que abrace o cubra el extremo con carraca de una llave fija combinada, de forma que, cuando introducimos un tornillo por el hueco interior del aro de apriete de extremo con carraca de una llave fija combinada, la cabeza del tornillo pasa por el hueco y no continúa sobrepasando axíaímente dicho hueco, porque se encuentra con el tope proporcionado por el gorra extraíble esto es debido a que, una de las caras del laterales del gorro tiene un hueco interior abierto con medidas menores que el hueco interior abierta del aro de apriete de la carraca, e invade el hueco libre que se queda interiormente dentro del aro de apriete de la llave de carraca, y es ésta cara, la que está en contacto, con la cara superior dela cabeza del tornillo o tuerca. Estas medidas también coinciden generalmente conla zona de apriete del extremo de llave fija de la llave combinada  Explaining in greater detail, the system consists in the use of a removable and reversible cap (tighten and loosen) so that it embraces or covers the ratchet end of a combined fixed wrench, so that, when we introduce a screw through the inner hole of the end clamping ring with ratchet of a combined fixed wrench, the head of the screw passes through the hole and does not continue to exceed said hole axially, because it meets the stop provided by the removable cap this is because, one of the The sides of the hat have an open inner hollow with smaller measures than the open inner hollow of the ratchet, and it invades the free hole that stays inside inside the ratchet of the ratchet, and is this face , the one in contact, with the upper face of the screw or nut head. These measures also generally coincide with the tightening zone of the fixed key end of the combined key
BREVE DESCRIPCIÓN DE LOS DIBUJOS BRIEF DESCRIPTION OF THE DRAWINGS

En su conjunta, ésta tapa ofrece cierta solidez y a la vez cierta flexibilidad además ésta material irá en fundón del medio en el que se utilice por ejemplo, el NBR para entornos de trabajo en talleres. In Figures 1A and 1 B we can see a cap with a rounded shape (3), which covers the end with ratchet of the combined wrench, or has a similar shape to the outside of this end (sometimes it has a semi-elliptical shape) which , it is made of hard material but flexible as a whole or in parts, metallic (sheet metal or steel, stainless), hard or plastic silicas, plastic filaments with combinations of rubber material flexiprín! of 3D printers, rubber, for example. Similar to the hard plastic of a milk or soft drink lid, this lid, on the narrower side, is more flexible than on the top face of the lid, which is more rigid or dense. As a whole, this cover offers some solidity and at the same time some flexibility in addition this material will go in the middle of the medium in which it is used, for example, the NBR for work environments in workshops.
Este gorro, tiene una abertura por la que normalmente se introduce dicho extremo de la llave combinada se puede identificar como el hueco o espacio entre los extremos 4 1 y 4.2 del gorro), generalmente, éste podrá tener unos pequeños cortes en sus laterales para facilitar su inserción  This cap has an opening through which said end of the combined wrench is normally inserted, which can be identified as the hole or space between the ends 4 1 and 4.2 of the cap), generally, it may have small cuts on its sides to facilitate its insertion
Este gorro, cubre preferiblemente hasta donde comienza el mango del extremo con carraca de la llave fija combinada (véase figura 2A. y 2B extremos del gorro 4.1 y 4.2)This cap preferably covers as far as the handle of the end with ratchet of the combined fixed wrench begins (see figure 2A. And 2B ends of the cap 4.1 and 4.2)
Ei material y flexibilidad del gorro permite expandirse y/o abrirse para introducir la parte más gruesa del extremo con carraca de la llave combinada, y recuperar su forma una vez colocado en su sitio para impedir en la medida de lo posible la extracción axial (si se introduce por el hueco entre los extremos del gorro 4.1 y 4.2, pues impedir que se vuelva a salir por dicho lugar) del gorro con respecto a la llave combinada The material and flexibility of the hat allows it to expand and / or open to introduce the thickest part of the ratchet end of the combined wrench, and recover its shape once placed in place to prevent axial extraction as far as possible (if it is introduced through the gap between the ends of the hat 4.1 and 4.2, as it prevents it from coming out again through that place) of the hat with respect to the combined wrench
En ios extremos del gorro (4.1 y 4.2) se le puede colocar una pequeña aleta rígida (5) (figura 1 A y 5 A), para poder abrir o extraer fácilmente el gorro cuando el gorro sea de material más rígido, por ejemplo, metálico, éstas aletas puedan estar colocadas hada el lado contrario donde hace contacto los extremos del gorro con la llave At the ends of the hat (4.1 and 4.2) you can place a small rigid flap (5) (Figure 1 A and 5 A), so that you can easily open or remove the hat when the hat is made of more rigid material, for example, metallic, these fins can be placed on the opposite side where the ends of the hat make contact with the key
Este gorro, consta de dos superficies laterales principales, a las que vamos a llamar cara A y cara 8 o lados (1 y 2), la cara A (2) (figura 1 A) tiene un hueco Interior abierto circular o semi-circuiar (aunque ésta es la forma preferida, puede tener otras, por ejemplo triangular o hexagonal, véase figura (5 A), de diámetro menor que el hueco interior circular abierto de la cara B ( 1 )(figura I B), éste hueco interior abierto además es más pequeño que el hueco interior abierto del anillo de apriete (7)(figuras 2A y 2B) del extreme con carraca, siendo éste hueco interior abierto del aro de apriete (7) de la llave combinada, el hueco por donde se introduce la parte superior de un tornillo, de manera que, la parte intema (2.1) de la superficie útil que queda en esta cara A (2), cubre parte del hueco abierto del aro de apriete (7) y hace de tope, en la parte superior de la cabeza de un tornillo, cuando se introduce éste a través del hueco del aro de apriete (7) del extremo con carraca, por el lado de la cara B (1}(figura 2B)de l gorro, a modo de ejemplo, si el hueco interior abierto o anillo de apriete (7) de la parte con carraca de una llave combinada está preparada para apretar tomillos con cabeza hexagonal de 10 mm, ésta cara A (2) tiene un diámetro de hueco interior abierto para apretar tornillos de cabeza hexagonal de 8 mm de diámetro. This cap consists of two main lateral surfaces, which we are going to call face A and face 8 or sides (1 and 2), face A (2) (figure 1 A) has a circular or semi-circular open interior (Although this is the preferred form, it may have others, for example triangular or hexagonal, see figure (5 A), smaller in diameter than the open circular inner hollow of face B (1) (Figure IB), this open inner hollow it is also smaller than the open inner hole of the clamping ring (7) (figures 2A and 2B) of the ratchet end, this inner hollow being open of the clamping ring (7) of the combined wrench, the hole through which the part is introduced top of a screw, so that the internal part (2.1) of the useful surface that remains on this face A (2), covers part of the open hole of the clamping ring (7) and stops, in the upper part of the head of a screw, when it is introduced through the hole of the clamping ring (7) of the end with ratchet, by the side of the face B (1} (figure 2B) of the cap, by way of example, if the open inner hole or clamping ring (7) of the ratchet portion of a combination wrench is prepared to tighten 10 mm hexagonal head screws, this side A (2) has an open inner hole diameter for tightening screws 8mm diameter hexagonal head.
En otra forma de realización, el gorro (3) tiene una cara A2 (2 2) que no tiene hueco interior abierto (figuras 3A y 38) puesto que está cerrado Este cierre o hueco cerrado no liega hasta ios extremos (4 1 y 4 2) o base del gorro, ver punto 8 en la figura 38, para tener más flexibilidad y poder introducir o extraer el gorro fácilmente, esto también permite que, si la llave fija combinada tiene selector de inversión de giro éste no quede cubierto  In another embodiment, the cap (3) has an A2 face (2 2) that has no open inner hole (Figures 3A and 38) since it is closed. This closed closure or gap does not reach the ends (4 1 and 4). 2) or base of the hat, see point 8 in figure 38, to have more flexibility and to be able to easily insert or remove the hat, this also allows that, if the combined fixed wrench has a reversing selector, it is not covered
La funcionalidad de que el gorro (3), tenga dicho agujero interior (ejemplos figuras 7 A y 7B) es la de permitir apretar tuercas ya que estas giran sobre un esparrago Interior o una varilla roscada que atravesara dicho hueco interior La parte útil interior de la cara A (2 1) puede tener colocado una pieza metálica que puede engrasarse y estar magnetizada, de manera que, cuando se gire un tornillo se reduzca el deterioro del gorro según material y se facilite el rozamiento o fricción entre la superficie de contacto de dicha cara interior (2.1 ) y la cabeza del tomillo permitiendo un desplazamiento entre ios mismos.  The functionality of the cap (3) having said inner hole (examples Figures 7 A and 7B) is to allow tightening nuts as they rotate on an inner stud or a threaded rod that crosses said inner hole The inner useful part of face A (2 1) may have a metal part in place that can be greased and magnetized, so that, when a screw is turned, the deterioration of the cap according to material is reduced and friction or friction between the contact surface of said inner face (2.1) and the head of the thyme allowing a movement between them.
La otra da las caras del gorro que es la cara B (1 ) (figura 18), tiene un hueco circular o semicircular interior abierto de diámetro mayor que el de la cara A (1 ), y a su vez, también es menor que el hueco interior abierto del anillo o aro de apriete (7) de la parte con carraca de la llave combinada, de manera que sujete o abrace ese lateral de la parle con carraca impidiendo que se saiga el gorro, cuando se hace presión con la cabeza del tornillo en la parte inferior de la cara A (2) del gorro, pero sin disminuir o tapar el agujero interior abierto o aro de apriete (7) en la parte con carraca de una liave combinada y poder así introducir la cabeza de un tornillo  The other gives the faces of the cap that is face B (1) (figure 18), has an open circular or semicircular hollow with a diameter greater than that of face A (1), and in turn, is also smaller than the open inner hollow of the ring or clamping ring (7) of the part with ratchet of the combined wrench, so that it holds or hugs that side of the parle with ratchet preventing the hat from being removed, when pressure is made with the head of the screw in the lower part of face A (2) of the cap, but without diminishing or covering the open inner hole or clamping ring (7) in the ratchet part of a combined liave and thus being able to introduce the head of a screw
Puesto que hablamos de la reversibilidad del gorro, y conociendo que la llave combinada es reversible por el extremo con carraca de la liave combinada, éste gorro también as reversible de manera que, según sea para apretar o aflojar la cabera de un tornillo, la cara interior (2.1) de éste gorro irá colocada, de manera que haga tope en el lado contrario por el que se introduce la cabeza del tornillo o tuerca Since we are talking about the reversibility of the hat, and knowing that the combined wrench is reversible by the ratchet end of the combined hatch, this hat is also reversible so that, depending on whether to tighten or loosen the head of a screw, the inner face (2.1) of this cap will be placed, so that it stops on the opposite side through which the screw or nut head is inserted
Las medidas da los huecos interiores abiertos de las dos caras del gorro, irán proporcionalmente. en fundón del diámetro de apriete de la parte con carraca de la llave combinada de manera que, una de ias caras (2) hace de tope para la cabeza el tornillo o tuerca, y la otra de las caras (1 ), hace de sujeción en el lado contrario de la cara A (1 ) para impedir que se salga del sitio el gorro, cuando la cabeza del tornillo haga presión enla cara interior (2.1) de la cara A (2) del gorro.  The measurements give the open interior holes of the two faces of the hat, will go proportionally. in cast iron of the tightening diameter of the ratchet part of the combined wrench so that one of the faces (2) makes the screw or nut stop for the head, and the other of the faces (1), holds on the opposite side of face A (1) to prevent the hat from leaving the site, when the screw head presses on the inside face (2.1) of face A (2) of the hat.
Las medidas del gorro, serán las medidas adecuadas para abrazar la parte exterior del extremo con carraca de la llave fija combinada, o un poco más grande si es para utilizarlo en el extremo de llave fija También se puede utilizar una medida Intermedia entre ios dos extremos (gorro 3.1). The measures of the hat, will be the appropriate measures to embrace the outer part of the end with ratchet of the combined fixed key, or a little larger if it is to use it in the end of fixed key. An Intermediate measurement can also be used between the two ends (cap 3.1).
En otra forma de realización los laterales de los extremos del gorro están alargados a modo de patas con uno de los extremes más curvo. (Figure 5 A y 5 B).  In another embodiment the sides of the ends of the cap are elongated by way of legs with one of the most curved ends. (Figure 5 A and 5 B).
Puesto que las llaves fijas o el extremo de llave fija de las llaves combinadas tienen uno de los laterales de la zona de apriete más largo y cóncavo, en esta forma de realización del gorro (3.2, figura 5A) haremos un gorro, que tenga la medida exterior del extremo con carraca de una llave fija combinada de forma que uno de los laterales de los extremos del gorro (3.2), (por ejemplo el lateral (10.2) correspondiente ai extremo (4.2) tenga una forma exterior más cóncava y/o más larga adaptada a ese lateral exterior más cóncavo de una llave fija.  Since the fixed keys or the fixed key end of the combined keys have one of the sides of the longest and most concave tightening zone, in this embodiment of the cap (3.2, figure 5A) we will make a cap, which has the outer measure of the ratchet end of a fixed wrench combined so that one of the sides of the cap ends (3.2), (for example the side (10.2) corresponding to the end (4.2) has a more concave and / or outer shape longer adapted to that more concave outer side of a fixed key.
Como se pueden ver en ias figuras los huecos interiores abiertos de los laterales o caras del garro tienen una parte que es circular, similar al del aro de apriete de las llaves combinadas pero sus dimensiones tendrán las características descritas anteriormente y además pueden tener una parte alargada en los extremos del gorra (3.3) para que se amolde a la forma del extremo con carraca de la llave combinada (en el caso de tener otra forma dicho extremo con carraca, por ejemplo, semi-eliptica. ver figura 56) As can be seen in the figures, the open interior gaps of the sides or sides of the claw have a part that is circular, similar to the tightening ring of the combined wrenches but their dimensions will have the characteristics described above and can also have an elongated part at the ends of the cap (3.3) so that it fits into the shape of the ratchet end of the combined wrench (in the case of having another shape said end with ratchet, for example, semi-elliptic. see figure 56)
Las superficies útiles de las dos caras principales del gorro (A y B), tienen forma circular o semi circular pero principalmente la cara A (2) puede tener otras formas que presenten mejores características según queramos tapar más superficie abierta del hueco inferior del aro de apriete (7) de la carraca por ejemplo, forma triangular(figura 5 A Y 6 A), forma semi elíptica dejando un hueco interior abierto de un diámetro determinado para que lo atraviese el esparrago estriado en el que gira una tuercaThe useful surfaces of the two main faces of the hat (A and B), have a circular or semi-circular shape but mainly the face A (2) can have other shapes that have better characteristics as we want to cover more open surface of the lower hole of the hoop of tighten (7) of the ratchet for example, triangular shape (figure 5 A and 6 A), semi-elliptical shape leaving an open inner hole of a certain diameter to pass through the striated stud in which a nut rotates
En las figuras 4 A y 4B. se puede ver un gorro (3.1) colocado en el extremo de llave fija de la lave combinada con carraca en el cual se distingue, que la forma del hueco interior de la cara A del gorro es cuadrada, aunque puede ser hexagonal u otras más adecuadas. In figures 4 A and 4B. you can see a cap (3.1) placed on the end of the fixed wrench of the wash combined with ratchet in which it is distinguished, that the shape of the inner hollow of the face A of the cap is square, although it may be hexagonal or other more suitable.
