Abstract

The projectile (1) comprises a body containing a front part (2) and a rear part (3), which is hollow. An axial pin (4) is embedded in the front part and secured under pressure. Said pin, which culminates in a hard point (6) located towards the front, is conical in shape and finished off in the shape of helmet (7). The aforementioned point (6) covers the front end of an air chamber (5) which is formed axially in part (2) of the projectile body (1), in such a way that, with the impact of the latter, the point (6) moves towards the inside of the chamber (5) creating a compression in the chamber and thereby converting the projectile (1) into a pellet. The projectile body (1) is cylindrical and the external helicoidal grooves, as with the body which they form, are made of lead having a high antimony content, and owing to the high degree of hardness thereof, they remain intact when fired, which, together with the rear hollow part (3), provides a high level of precision in the trajectory. The projectile, because of the way it is mounted on the weapon, is arranged on a container, wherein it is retained, and which, moreover, acts as a pressure dampening element and as a stopper for the gases that originate when the device is fired.

OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a un proyectil subcalibrado y previsto para ser montado en un contenedor en el qμe queda convenientemente retenido, todo ello en orden a conseguir una total inmovilización del proyectil en el interior del cartucho y posteriormente en el cañón del arma de disparo, sirviendo el contenedor de medio amortiguador de presión y de obturador de los gases del disparo. El proyectil subcalibrado está materializado en un cuerpo monopieza que se complementa con un vastago axial que queda embebido a presión en el interior del cuerpo del proyectil, y cuyo vastago se remata en una punta cónica, sobresaliendo ésta por el extremo anterior del proyectil, contando además con estrías helicoidales externas, según un plano notablemente inclinado, que le proporcionan una velocidad giroscópica elevada y una precisión excepcional en el giro.The present invention relates to a subcalibrated projectile and intended to be mounted in a container in which it is conveniently retained, all in order to achieve total immobilization of the projectile inside the cartridge and subsequently in the barrel of the firing weapon, serving the container of pressure damping medium and shutter of the flue gases. The subcalibrated projectile is materialized in a single piece body that is complemented by an axial rod that is embedded under pressure inside the projectile body, and whose rod is capped in a conical tip, protruding from the front end of the projectile, also counting with external helical grooves, according to a remarkably inclined plane, which provide a high gyroscopic speed and exceptional turning accuracy.
El proyectil de la invención está previsto para ser lanzado por armas de fuego, concretamente escopetas, utilizadas en caza mayor.The projectile of the invention is intended to be launched by firearms, specifically shotguns, used in big game.
Es objeto de la invención proporcionar al mundo de los cazadores un proyectil que además de ofrecer un gran alcance debido a sus características particulares, así como una gran velocidad y precisión en el disparo, se convierte al impactar en el animal en metralla, lo que determina una eficacia máxima en el uso del propio proyectil. ANTECEDENTES DE LA INVENCIÓNIt is the object of the invention to provide the world of hunters with a projectile that, in addition to offering great range due to its particular characteristics, as well as high speed and accuracy in firing, is converted by impacting the animal in shrapnel, which determines maximum efficiency in the use of the projectile itself. BACKGROUND OF THE INVENTION
Los proyectiles utilizados en escopetas de caza suelen ser de superficie externa lisa, lo que da lugar a una carencia de estabilización en el disparo y un alcance no muy elevado, aunque no es menos cierto que existen proyectiles constituidos mediante dos cuerpos fijados entre sí, con el complemento de un vastago que además de ser pasante por los cuerpos y que constituyen el medio de fijación para éstos, se remata en una punta de mayor dureza que la de los cuerpos anteriormente referidos, siendo esa punta de configuración cónica determinando el medio frontal que ha de impactar en primer lugar sobre el blanco, generalmente sobre un animal .The projectiles used in hunting shotguns are usually of smooth external surface, which results in a lack of stabilization in the shot and a not very high range, although it is no less true that there are projectiles constituted by two bodies fixed to each other, with the complement of a rod that, in addition to being an intern for the bodies and that constitute the fixing means for these, is finished off at a point of greater hardness than that of the aforementioned bodies, being that point of conical configuration determining the frontal means that It has to impact first on the target, usually on an animal.
En base a ese tipo de proyectil cabe citar el reivindicado en el Modelo de Utilidad español 9902957 del mismo solicitante, en el que el extremo de la punta frontal es truncado, formando un cuerpo tronco-cónico, de manera que los dos cuerpos básicos del proyectil cuentan con medios complementarios de acoplamiento axial, realizándose la sujeción mediante una tuerca que rosca en el extremo posterior del vastago correspondiente al cuerpo tronco-cónico o punta anteriormente referida, complementándose el cuerpo posterior con una tapa de cierre de ocultación de la tuerca de apriete y fijación, mientras que en el cuerpo anterior se establece una cámara de aire que queda cerrada por la base del cuerpo tronco-cónico o punta anteriormente referida, siendo la configuración del cuerpo determinado por los dos anteriormente referidos, ligeramente tronco-cónica y estando afectado de estrías longitudinales aunque con una leve inclinación, y dotado posteriormente de una banda lisa que ajusta en el correspondiente alma del arma de fuego para evitar la fuga de gases originados en la explosión, consiguiéndose con ello una mayor efectividad en el disparo. DESCRIPCIÓN DE LA INVENCIÓNBased on this type of projectile, it is worth mentioning the one claimed in the Spanish Utility Model 9902957 of the same applicant, in which the end of the frontal tip is truncated, forming a conical trunk body, so that the two basic bodies of the projectile they have complementary axial coupling means, the fastening being carried out by means of a nut that threads at the rear end of the rod corresponding to the trunk-conical body or tip referred to above, the rear body being complemented with a cover for hiding the clamping nut and fixation, while in the anterior body an air chamber is established that is closed by the base of the trunk-conical body or tip referred to above, the body configuration being determined by the two previously referred to, slightly trunk-conical and being affected by longitudinal stretch marks although with a slight inclination, and subsequently equipped with a smooth band that aju This is in the corresponding soul of the firearm to prevent the leakage of gases originated in the explosion, thereby achieving greater effectiveness in firing. DESCRIPTION OF THE INVENTION

Más concretamente, el proyectil de la invención presenta un cuerpo único y de configuración cilindrica, con una parte posterior totalmente hueca para aligeramiento del peso y una parte anterior, en la que está ubicado axialmente el correspondiente vastago rematado en la punta frontal y dura del proyectil, siendo ésta de configuración cónica pero con su base externa en forma de casquete esférico, lo que determina un ajuste perfecto de dicha punta dura del vastago del proyectil sobre la embocadura de la cámara establecida en la parte anterior del cuerpo, ajustando el resto del vastago en éste último a presión para quedar perfectamente solidarizado al mismo.More specifically, the projectile of the invention has a unique body with a cylindrical configuration, with a completely hollow rear part for lightening the weight and an anterior part, in which the corresponding rod is located axially located on the hard front end of the projectile. , this being of conical configuration but with its external base in the form of a spherical cap, which determines a perfect adjustment of said hard tip of the projectile rod on the mouth of the chamber established in the front part of the body, adjusting the rest of the rod in the latter under pressure to be perfectly sympathetic to it.
Así mismo, se ha previsto que el número de estrías con que está afectada la superficie lateral del cuerpo del proyectil, sea concretamente de varias y con una notable inclinación, lo que permite dotar al proyectil de una velocidad giroscópica prácticamente igual a la conseguida mediante un rifle.Likewise, it is envisaged that the number of stretch marks with which the lateral surface of the projectile body is affected, is specifically several and with a notable inclination, which allows the projectile to be provided with a gyroscopic speed practically equal to that achieved by means of a rifle.
La parte hueca posterior del cuerpo del proyectil, además de aligerar en peso al mismo, permite equilibrar en vuelo su trayectoria, evitando cabeceos o desvíos al ser su parte delantera mucho más pesada que su parte posterior o cola. La naturaleza o material del cuerpo del proyectil es preferentemente de plomo con un alto contenido en antimonio, evitando con ello posibles deformaciones dentro del cañón del arma de disparo, aún cuando la presión a que se ve sometido sea la máxima, aproximadamente de 900 Kg/cm2, de manera que al no sufrir deformaciones dentro del cañón la precisión se ve aumentada puesto que conservará sus estrías intactas .The hollow rear part of the body of the projectile, in addition to lightening in weight to the same, allows to balance its trajectory in flight, avoiding headings or deviations as its front part is much heavier than its back or tail. The nature or material of the projectile body is preferably of lead with a high antimony content, thereby avoiding possible deformations within the firing gun barrel, even when the pressure to which it is subjected is the maximum, approximately 900 Kg / cm 2 , so that not suffering deformations inside the barrel the precision is increased since it will keep its stretch marks intact.
Así mismo, el proyectil subcalibrado de la invención ofrece la gran ventaja de no dañar en absoluto los estrangulamientos del arma, siendo el diámetro de aquél dos milímetros menor que la del cañón del arma o escopeta mediante la que se dispara.Likewise, the subcalibrated projectile of the invention offers the great advantage of not damaging at all the strangulation of the weapon, the diameter of the latter being two millimeters smaller than that of the barrel of the weapon or shotgun by which it is fired.
El proyectil referido presenta también la ventaja de que en el impacto de la punta, en forma de casquete, contra el animal, aquella se hunde y penetra en la cámara de aire establecida en la parte anterior del cuerpo del proyectil, transformándose en metralla y provocando una onda explosiva dentro del animal .The referred projectile also has the advantage that in the impact of the tip, in the form of a cap, against the animal, it sinks and penetrates into the air chamber established in the front part of the projectile body, transforming into shrapnel and causing An explosive wave inside the animal.
Dicho proyectil, como ya se ha dicho, se complementa con un contenedor determinado por unas lengüetas rectangulares distantes equiangularmente y dotadas en su cara interna de una uña para fijar el proyectil, a través de un escalón anular de éste en el que precisamente se alojan estas uñas. Las lengüetas emergen de una parte posterior cerrada en funciones de base, que está unida a unos medios de amortiguación. Dicho contenedor actúa como inmovilizador del proyectil en el cartucho y en el cañón del arma, sirviendo además de amortiguador de presión y de obturador de los gases de disparo, y está fabricado preferentemente en polietileno de densidad.Said projectile, as already said, is complemented with a container determined by rectangular tabs that are equiangularly distant and provided with a fingernail to fix the projectile on its inner face, through an annular step of the latter in which these are precisely housed. nail. The tabs emerge from a closed back in base functions, which is attached to a damping means. Said container acts as an immobilizer of the projectile in the cartridge and in the barrel of the weapon, also serving as a pressure damper and a shutter for the firing gases, and is preferably made of density polyethylene.
En una variante de realización, la parte hueca y posterior del cuerpo del proyectil está rellena de un material, preferentemente polietileno de alta presión, el cual es atravesado por el propio vastago axial, al prolongarse éste hacia la parte posterior, hasta la propia base inferior del cuerpo del proyectil, donde se fija a presión con rosca especial.In a variant embodiment, the hollow and rear part of the projectile body is filled with a material, preferably high pressure polyethylene, which is crossed by the axial rod itself, as it extends towards the rear, to the lower base of the projectile body itself, where it is fixed under pressure with a special thread.
En otra variante de realización, la punta cónica prevista en el extremo anterior del vastago, en lugar de ser en forma de casquete, es de configuración perfectamente cónica, apoyando a través de su base en el extremo plano en que se remata la parte anterior del cuerpo del proyectil .In another variant embodiment, the conical tip provided at the front end of the rod, instead of being in the form of a cap, is of a perfectly conical configuration, resting through its base at the flat end where the front part of the rod is finished. projectile body
En otra variante de realización, las lengüetas del contenedor, en lugar de estar dotadas en su cara interna de uñas de enelavamiento, están dotadas de unos resaltes arqueados a partir de los cuales y hasta el extremo libre de las lengüetas se determinan tramos o superficies inclinadas que al tomar el aire a presión se ve favorecida la apertura de las lengüetas para dejar libre al proyectil, facilitando así la salida o abandono de éste respecto del contenedor.In another variant embodiment, the tabs of the container, instead of being provided with in its internal face of raking nails, are provided with arcuate projections from which and even inclined surfaces are determined sections or inclined surfaces that when taking the air under pressure, the opening of the tabs is favored to free the projectile, thus facilitating the exit or abandonment of the projectile with respect to the container.

De esta manera, el contenedor (9) es el que retiene el proyectil (1) dentro del cañón del arma de disparo, sirviendo de amortiguador de presión y de obturador de los gases originados en el propio disparo.In this way, the container (9) is the one that retains the projectile (1) inside the barrel of the firing weapon, serving as a pressure damper and shutter of the gases originated in the firing itself.
La parte posterior hueca (3) del proyectil (1) , además de aligerar en peso a éste último está destinada a equilibrar en vuelo su trayectoria, evitando cabeceos o desvíos al ser mucho más ligera que la parte delanteraThe hollow back (3) of the projectile (1), in addition to lightening the latter in weight, is intended to balance its trajectory in flight, avoiding headings or deviations as it is much lighter than the front
(2) del mismo proyectil.(2) of the same projectile.
En cuanto a la cámara de aire (5) que se establece en la parte delantera (2) del proyectil, cuando la misma es comprimida en el impacto por la puntaAs for the air chamber (5) that is established at the front (2) of the projectile, when it is compressed on impact by the tip
(6) del vastago (4) , convierte a dicho proyectil (1) en metralla, con lo que la eficacia es óptima.(6) of the rod (4), converts said projectile (1) into shrapnel, so that the efficiency is optimal.
También cabe decir que se trata de un proyectil subcalibrado dotado de estrías helicoidales (l1) que proporcionan una velocidad giroscópica al mismo como si el proyectil fuese disparado por un rifle, consiguiendo además una precisión excepcional.It can also be said that it is a subcalibrated projectile equipped with helical grooves ( 1 ) that provide a gyroscopic speed to it as if the projectile was fired by a rifle, also achieving exceptional precision.
En una variante de realización mostrada en la figura 5, el hueco (3') de la parte posterior (3) está relleno de un material (15) preferentemente polietileno de alta presión, siendo ese material (15) atravesado por el propio vastago (4) que se prolonga hacia atrás y se fija por su extremo posterior mediante una rosca especial a presión (16) . Así mismo, cabe decir que el vastago (4) en lugar de tener el extremo (6) de superficie externa redondeada o en forma de casquete, presenta una configuración cónica (61) apoyando a través de su base sobre el extremo que define un plano correspondiente a la parte anterior (2) del cuerpo (1) del proyectil.In a variant embodiment shown in Figure 5, the recess (3 ') of the back (3) is filled with a material (15) preferably high pressure polyethylene, that material (15) being crossed by the rod itself ( 4) which extends backwards and is fixed at its rear end by means of a special press thread (16). Likewise, it should be said that the rod (4) instead of having the end (6) of rounded or capped outer surface, has a conical configuration (6 1 ) supporting through its base on the end that defines a plane corresponding to the anterior part (2) of the body (1) of the projectile.
En otra variante de realización, las lengüetas (10) del contenedor (9) , en lugar de estar dotadas de las uñas (11) cuentan con unos resaltes redondeados e internos (11') desde los cuales y hasta el extremo libre de tales lengüetas (10) se determinan tramos de superficie inclinada (17) que favorecen la salida del proyectil (1) respecto del contenedor (9) , ya que esos planos inclinados (17) permiten una mejor abertura de las lengüetas (10) cuando se produce la toma del aire a presión.In another variant embodiment, the tabs (10) of the container (9), instead of being provided with the nails (11) have rounded and internal projections (11 ') from which and to the free end of such tabs (10) sections of inclined surface (17) are determined that favor the exit of the projectile (1) with respect to the container (9), since those inclined planes (17) allow a better opening of the tabs (10) when the pressurized air intake.
El cuerpo del proyectil (1) puede carecer de las estrías (11) , es decir, presentar lisa su superficie externa, lo que permitiría su utilización en escopetas de cañón rayado e indistintamente en escopetas de cañón liso. The body of the projectile (1) may lack the stretch marks (11), that is to say, have its outer surface smooth, which would allow its use in shotgun barrels and interchangeably in smooth barrel shotguns.
