Description

Tornillo.Screw.

Objeto de la invenciónObject of the invention

La presente invención se refiere a un tornillo o tirafondos, del tipo de los destinados a ser accionados mediante un destornillador, pudiendo indistintamente roscar sobre una pieza de madera, sobre una chapa, o hacerlo sobre una tuerca, sin que el tipo de tornillo en sí mismo afecte a la esencia de la invención.The present invention relates to a screw or screws, of the type intended to be operated by a screwdriver, being able to interchangeably thread on a piece of wood, on a sheet, or on a nut, without the screw type itself affect the essence of the invention.

El objeto de la invención es dotar a dicho tornillo de una cabeza que asegure unas óptimas condiciones de manipulación sobre la misma, con el correspondiente destornillador, tanto durante las operaciones de implantación como de posible extracción del tornillo.The object of the invention is to provide said one head screw that ensures optimum conditions of handling on it, with the corresponding screwdriver, both during the implementation operations and as possible screw removal.

Antecedentes de la invenciónBackground of the invention

Existen fundamentalmente dos tipos de tornillos o tirafondos, los destinados a ser accionados mediante una llave de tuercas o una llave allen, y aquellos otros que están destinados a ser accionados mediante un destornillador.There are essentially two types of screws or screws, those intended to be operated by means of a key nuts or an allen wrench, and those others that are intended for Be operated by a screwdriver.

Dentro de este segundo grupo de tornillos o tirafondos existen a su vez dos variantes, una la clásica, en la que la cabeza del tornillo cuenta con una ranura diametral, y otra la denominada "Philips" en la que la cabeza del tornillo presenta un rehundido piramidal de sección estrellada.Within this second group of screws or There are also two variants, one classic, in the that the screw head has a diametral groove, and another the so-called "Philips" in which the screw head presents a pyramidal recess of starry section.

Los tornillos de cabeza diametralmente ranurada presentan una problemática que se centra fundamentalmente en dos aspectos, por un lado existe una tendencia importante a que la pala del destornillador se desacople de dicha ranura, lo que hace incómodo y molesto el atornillamiento, y por otro lado en pocas ocasiones la sección de la pala del destornillador coincide con la anchura de la ranura del tornillo, de manera que existe una holgura que hace que el esfuerzo se aplique de forma prácticamente puntual, lo que produce el deterioro y en muchos casos inutilización del tornillo por deformación de su cabeza.Diametrically slotted head screws present a problem that focuses primarily on two aspects, on the one hand there is an important tendency for the blade of the screwdriver is disengaged from said slot, which makes uncomfortable and annoying screwing, and on the other hand in a few Sometimes the section of the screwdriver blade matches the screw groove width, so there is a slack which makes the effort be applied practically on time, what causes the deterioration and in many cases uselessness of the head deformation screw.

Esta problemática se ve resuelta, en los dos aspectos comentados, mediante los tornillos tipo "Philips", donde la punta del destornillador actúa sobre la cabeza del tornillo en cuatro zonas o caras angularmente distribuidas, que además convergen sobre el vértice de la pirámide, de manera que el destornillador tiende automáticamente al auto-centrado y además potencia su superficie de contacto con la cabeza del tornillo. Sin embargo estos tornillos "Philips" presentan a su vez un problema y es que por su propia configuración tendente al cono actúan a modo de leva que tiende a desplazar el destornillador hacia fuera, requiriéndose de un considerable esfuerzo axial sobre el mismo, hasta el punto de que cuando se utilizan atornilladores eléctricos en muchas ocasiones la punta-destornillador salta sobre los facetados del alojamiento de la cabeza del tornillo, produciendo un rápido deterioro de la misma, deterioro que a mayor plazo se hace extensivo también al propio destornillador.This problem is solved, in both commented aspects, using the "Philips" type screws, where the tip of the screwdriver acts on the head of the screw in four zones or angularly distributed faces, which they also converge on the apex of the pyramid, so that the screwdriver automatically tends to self-centered and also enhances its surface of Screw head contact. However these screws "Philips" in turn present a problem and that is because of its own configuration tending to the cone act as a cam that tends to move the screwdriver out, requiring considerable axial effort on it, to the point of that when electric screwdrivers are used in many Sometimes the screwdriver tip jumps over the faceted screw head housing, producing a rapid deterioration of the same, deterioration that is made in the longer term Extensive also to the screwdriver itself.

Descripción de la invenciónDescription of the invention

El tornillo que la invención propone reúne las ventajas de los dos tipos de tornillo anteriormente citados, sin ninguno de sus inconvenientes.The screw proposed by the invention brings together the advantages of the two screw types mentioned above, without None of its drawbacks.

Para ello y de forma mas concreta dicho tornillo presenta sobre la cara externa de su cabeza dos ranuras cruzadas en forma de cruz, cada una de las cuales es similar a la ranura diametral y única de los tornillos o tirafondos convencionales, de manera que utilizando un destornillador con una forma también en forma de cruz, formal y dimensionalmente adecuada a la cabeza del tornillo, se consigue mantener estable el acoplamiento del destornillador sobre el tornillo, al quedar dicho destornillador inmovilizado tanto en sentido de una de las ranuras como en sentido de la otra, es decir aportando las prestaciones de estabilización al conjunto del destornillador- tornillo de un tornillo convencional tipo "Philips", pero al tratarse de ranuras de sección constante y con frentes rectos, evitando el problema de dichos tornillos "Philips" que tienden a la auto-salida de la punta del destornillador, punta que en este caso no se ve sometida a ningún esfuerzo axial por lo que se mantiene también estable en el alojamiento de la cabeza del tornillo, no sólo en el sentido angular sino también en el sentido
axial.
To do this, and more specifically, said screw has two cross-shaped cross grooves on the outer face of its head, each of which is similar to the diametral groove and unique to conventional screws or screws, so that using a screwdriver with a shape also in the form of a cross, formally and dimensionally appropriate to the head of the screw, it is possible to maintain stable the screwdriver coupling on the screw, when said screwdriver is immobilized both in the direction of one of the grooves and in the direction of the another, that is to say by providing the stabilization benefits to the screwdriver-screw assembly of a conventional "Philips" type screw, but since they are grooves of constant section and with straight fronts, avoiding the problem of said "Philips" screws that tend to self-exit of the tip of the screwdriver, tip that in this case is not subjected to any axial effort so it is also maintained Stable in the screw head housing, not only in the angular direction but also in the direction
axial.

Realización preferente de la invenciónPreferred Embodiment of the Invention

A la vista de las figuras reseñadas puede observarse como el tornillo que se preconiza, como cualquier tornillo convencional, está constituido mediante un vástago roscado (1), rematado por uno de sus extremos en la clásica cabeza (2), constitutiva del medio de accionamiento de dicho tornillo, así como de tope limitador de penetración en la pieza de que se trate, mientras que su otro extremo se remata en una punta cónica (3), preferentemente provista de rebordes afilados (4), a modo de cuchillas, que confieren al tornillo un carácter auto-perforante. No obstante y como ya se ha apuntado con anterioridad, el tornillo puede tener cualquier otro tipo de configuración en su extremidad libre, incluida la interrupción brusca del vástago roscado (1), para recepción de una tuerca complementaria.In view of the figures outlined you can be observed as the recommended screw, like any conventional screw, is constituted by a threaded rod (1), topped by one of its ends in the classic head (2), constituting the driving means of said screw, as well as of penetration limit stop in the part in question, while its other end is finished off in a conical tip (3), preferably provided with sharp edges (4), by way of blades, which give the screw a character self-piercing However, as has already been done noted above, the screw can have any other type of configuration at its free end, including the abrupt interruption of the threaded rod (1), to receive a complementary nut

Pues bien, de acuerdo ya con la invención y tal como se observa especialmente en las figuras 2 y 3, el tornillo incorpora en su cabeza (2) una doble ranura (5), concretamente una ranura en cruz de brazos equiangularmente distribuidos e idénticos entre sí, ranura con una sección rectangular a su vez muestra la figura 1.Well, according to the invention and such as seen especially in figures 2 and 3, the screw incorporates in its head (2) a double groove (5), specifically a cross groove of equiangularly distributed and identical arms each other, slot with a rectangular section in turn shows the Figure 1.

Los brazos de la citada ranura en cruz (5) pueden estar abiertos por sus extremos, como el ejemplo de la realización práctica de las figuras 1 y 3, o estar cerrados como en la representación de la figura 2, sin que ello afecte a la esencia de la invención.The arms of the aforementioned cross slot (5) they can be open at their ends, as the example of the practical embodiment of figures 1 and 3, or be closed as in the representation of figure 2, without affecting the essence of the invention.

En cualquier caso el tornillo estará destinado a ser accionado con un nuevo destornillador, que con cualquier configuración o diseño convencional incorporará como punta de ataque una cruz formal y dimensionalmente coincidente con la ranura (5) y enchufable en el seno de la misma, preferentemente con un considerable ajuste.In any case the screw will be destined to be operated with a new screwdriver, which with any conventional configuration or design will incorporate as a tip of attack a cross formally and dimensionally coincident with the groove (5) and pluggable therein, preferably with a considerable adjustment.

Se consigue de esta manera que el arrastre del tornillo se realice actuando el destornillador sobre los cuatro brazos de la ranura (5), es decir con unas óptimas condiciones en cuanto al reparto de esfuerzos, y sin que exista tendencia al desacoplamiento del destornillador, ni en sentido angular ni en sentido axial, por la disposición paralela al eje del tornillo de los planos (6) de apoyo para el destornillador definidos por las paredes laterales de la ranura en cruz (5).It is achieved in this way that the drag of the screw is made by operating the screwdriver on the four groove arms (5), that is to say with optimal conditions in as for the distribution of efforts, and without any tendency to screwdriver decoupling, neither angularly nor in axial direction, by the arrangement parallel to the axis of the screw the screwdriver support planes (6) defined by the side walls of the cross groove (5).
