OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención, según lo expresa el enunciado de esta memoria descriptiva, se refiere a una bocacha para lanzamiento de proyectiles, perfeccionada, y como tal comporta notables características relevantes y ventajosas frente a las que se utilizan con el mismo fin y que son de su tipo.The present invention, as expressed in the statement of this specification, refers to a mouth for projectile launching, perfected, and as such entails significant relevant and advantageous characteristics compared to those used for the same purpose and which are of its kind.
Este tipo de bocachas se acoplan por roscado al cañón del arma para posibilitar el lanzamiento de pelotas de goma y botes de humo por parte de las fuerzas antidisturbios principalmente y para disolver manifestaciones, etc.These types of sandwiches are threaded to the barrel of the weapon to enable the launch of rubber balls and smoke boats by riot forces mainly and to dissolve demonstrations, etc.
ANTECEDNETES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
En el modelo de utilidad U 8901801 se contempla una bocacha para lanzamiento de proyectiles, que presenta una estructura que resuelve en parte los problemas inherentes a otras bocachas convencionales, pero no tan satisfactoriamente como era de desear.In the utility model U 8901801, a mouth for projectile launches is contemplated, which has a structure that partially resolves the problems inherent in other conventional mouths, but not as satisfactorily as was to be desired.
El cuerpo tubular de esta bocacha tenía orificios radiales de distinto diámetro para permitir variar la fuerza de lanzamiento al seleccionar uno y otro orificio de salida de los gases de expulsión, siendo obturado parcial o totalmente por un anillo de regulación dotado de unos medios de fijación en distintas posiciones angulares, materializados por una bola asistida por resorte en dirección radial, la cual se podía alojar en unas huellas o marcas longitudinales en la periferia del cuerpo.The tubular body of this mouth had radial holes of different diameter to allow varying the release force when selecting one or the other exit hole of the expulsion gases, being partially or totally sealed by a regulation ring provided with fixing means in different angular positions, materialized by a radial-assisted spring ball, which could be accommodated in longitudinal marks or marks on the periphery of the body.
El anillo se retenía axialmente por un circlip exterior calado en una garganta anular del cuerpo. El desplazamiento angular está limitado por un saliente radial del anillo que juega en una ranura de la pared anular del cuerpo .The ring was axially retained by an open outer circlip in an annular throat of the body. The angular displacement is limited by a radial projection of the ring that plays in a groove in the annular wall of the body.
El acoplamiento de la bocacha al cañón del arma se realiza directamente por roscado. DESCRIPCIÓN DE LA INVENCIÓNThe coupling of the mouth to the barrel of the weapon is done directly by threading. DESCRIPTION OF THE INVENTION
En líneas generales, la bocacha para lanzamiento de proyectiles, perfeccionada, objeto de la invención, está constituida análogamente por un cuerpo tubular escalonado.In general, the improved projectile launching mouth, object of the invention, is similarly constituted by a staggered tubular body.
En él se distingue un extremo de menor diámetro para acoplar al cañón del arma; otro extremo de mayor diámetro y con fondo troncocónico donde se recibe al proyectil; y una porción intermedia en la que se encuentra el anillo de regulación de los gases de salida.In it an end of smaller diameter is distinguished to fit the gun barrel; another end of greater diameter and with truncated cone where the projectile is received; and an intermediate portion in which the outlet gas regulation ring is located.
El acoplamiento de la bocacha al arma se realiza por intermedio de un casquillo que define un adaptador de la bocacha al cañón del arma, pudiéndose montar así la misma bocacha en diferentes armas sin más que retirar el casquillo y montar el correspondiente a ese cañón.The coupling of the bocacha to the weapon is carried out by means of a bushing that defines an adapter from the bocacha to the gun barrel, thus being able to mount the same bocacha in different weapons without removing the cap and mounting the corresponding one to that cannon.
La extremidad de mayor diámetro ofrece un borde redondeado para no presentar bordes que pudieran causar accidentes, y una pared interior totalmente lisa, libre de estrías, además de ofrecer un fondo cónico para asentamiento de la pelota de goma, en lugar del esférico habitual. La pelota sale lanzada recta y el alojamiento es fácil de limpiar.The limb of greater diameter offers a rounded edge so as not to present edges that could cause accidents, and a totally smooth interior wall, free of stretch marks, in addition to offering a conical bottom for settlement of the rubber ball, instead of the usual spherical. The ball is thrown straight and the housing is easy to clean.
El anillo de regulación es posicionado en la ubicación angular deseada mediante una disposición axial para la bola y su muelle en un punto del anillo, la cual puede confrontar con una de las huellas o entallas previstas en la superficie anular frontal del escalonamiento del cuerpo tubular. Esta disposición axial de conexión de la bola y entalla facilita el montaje y no hay peligro de roturas. Los límites de giro a uno y otro lado para este anillo se consiguen también con un espárrago fijado al anillo y que juega en una ranura del cuerpo, pero según una disposición axial para el espárrago roscado en el anillo, cuyo extremo juega en una ranura arqueada del frontal anular del cuerpo. El anillo queda inmovilizado axialmente mediante una tuerca de retención roscada en el cuerpo, en una zona adyacente al anillo, estando partida o abierta esta tuerca para ser bloqueada en la posición de montaje con un tornillo que aproxima sus dos planos de corte.The regulation ring is positioned in the desired angular location by means of an axial arrangement for the ball and its spring at a point in the ring, which can be confronted with one of the fingerprints or notches provided on the front annular surface of the staggered tubular body. This axial connection arrangement of the ball and notch facilitates assembly and there is no danger of breakage. The limits of rotation on either side for this ring are also achieved with a stud fixed to the ring and which plays in a groove of the body, but according to an axial arrangement for the threaded stud in the ring, whose end plays in an arcuate groove. of the annular frontal of the body. The ring is axially immobilized by means of a threaded retaining nut in the body, in an area adjacent to the ring, this nut being split or open to be locked in the mounting position with a screw that approximates its two cutting planes.

DESCRIPCIÓN DE LA FORMA DE REALIZACIÓN PREERIDA Haciendo referencia a la numeración adoptada en las figuras, podemos ver cómo la bocacha para lanzamiento de proyectiles, perfeccionada, que la invención propone, está referenciada en general con el número 1 y queda acoplada al extremo roscado del cañón 2 del arma por intermedio del casquillo adaptador 3 roscado a su cuerpo 4 como se ve en la figura 1.DESCRIPTION OF THE PREFERRED EMBODIMENT With reference to the numbering adopted in the figures, we can see how the perfected projectile launching mouth, which the invention proposes, is generally referenced with the number 1 and is coupled to the threaded end of the barrel 2 of the weapon through the adapter sleeve 3 threaded to its body 4 as seen in Figure 1.
En las figuras 4 a 7 se observa la geometría del cuerpo 4, y en las figuras 13 y 14 la del casquillo 3.In figures 4 to 7 the geometry of the body 4 is observed, and in figures 13 and 14 that of the sleeve 3.
El cuerpo 4 es tubular cilindrico y presenta exteriormente tres zonas bien diferenciadas: la referenciada con 5 que es la de menor diámetro y en ella rosca interiormente el casquillo adaptador 3; la de referencia 6 que es la de mayor diámetro y define la boca de carga del proyectil y de salida del mismo; y la zona central o intermedia 7 en la que va montado el anillo de regulación 8 y su tuerca de retención 9. En la figura 1 se ven estos elementos 8 y 9. El anillo de regulación 8 está montado en la parte lisa 10 y la tuerca de retención 9 en la zona roscada 11. La parte interior del cuerpo tubular 4 tiene un roscado 12 en su extremo 5 de menor diámetro para acoplamiento del casquillo 3 adaptador y en el extremo de mayor diámetro 6 ofrece una superficie lisa con un pequeño realce anular próximo al borde redondeado 13. Entre el realce anular y el reborde redondeado 13 se ha previsto una zona roscada para el acoplamiento de un tubo lanzador de botes de humo o de gases lacrimógenos, como el mostrado parcialmente en la figura 1. El fondo es troncocónico, está referenciado con 14 y sobre él asienta perfectamente la pelota de goma no mostrada en las figuras. Las referencias 15 y 16 designan los orificios radiales de distinto diámetro del cuerpo 4 en la zona central 10 cubierta por el anillo de regulación 8. En las figuras 5 y 6 se ve la distribución de estos orificios que serán parcial o totalmente cubiertos por el anillo 8 de regulación, provisto igualmente de los orificios diametrales 17 de salida de gases.The body 4 is cylindrical tubular and has three distinct zones externally: the one referenced with 5 which is the one with the smallest diameter and internally threaded the adapter sleeve 3; that of reference 6, which is the one with the greatest diameter and defines the loading port of the projectile and its exit; and the central or intermediate zone 7 in which the regulating ring 8 and its retaining nut 9 are mounted. Figure 1 shows these elements 8 and 9. The regulating ring 8 is mounted on the smooth part 10 and the retaining nut 9 in the threaded zone 11. The inner part of the tubular body 4 has a threaded 12 at its end 5 of smaller diameter for coupling of the adapter sleeve 3 and at the end of larger diameter 6 it offers a smooth surface with a small enhancement annular next to the rounded edge 13. Between the annular enhancement and the rounded edge 13 a threaded area for the coupling of a launching tube of smoke or tear gas canisters, such as partially shown in figure 1. The bottom is conical, is referenced with 14 and on it sits perfectly the rubber ball not shown in the figures . References 15 and 16 designate the radial holes of different diameter of the body 4 in the central area 10 covered by the regulating ring 8. In figures 5 and 6 the distribution of these holes is shown, which will be partially or totally covered by the ring 8 for regulation, also provided with the diametric orifices 17 for the gas outlet.
En las figuras 10 a 12 se ve la geometría del anillo de regulación 8, su estriado externo, los orificios 17 y también dos orificios axiales 18 y 19 para ubicar los medios de emplazamiento en distintas posiciones angulares, en colaboración con las muescas 20 y ranura arqueada 21Figures 10 to 12 show the geometry of the regulating ring 8, its outer groove, the holes 17 and also two axial holes 18 and 19 to locate the positioning means in different angular positions, in collaboration with the notches 20 and groove arched 21
(ver figura 6) previstas al efecto en la pared anular frontal del cuerpo. En la figura 3 se observa que el orificio 19 es liso y en él queda introducido el muelle 22 y la bola 23, posicionándose ésta establemente al encontrar cualquiera de dichas muescas o huellas 20.(see figure 6) provided for this purpose in the front annular wall of the body. In figure 3 it is observed that the hole 19 is smooth and in it the spring 22 and the ball 23 are introduced, this being stably positioned when finding any of said notches or tracks 20.
También en la figura 3 se ve referenciado con 24 el espárrago roscado montado en el segundo orificio 18 del anillo de regulación 8, roscado con este fin. El espárrago roscado 24 se remata en la prolongación lisa emergente 25 que juega en la ranura arqueada 21 (ver figura 6) referida, marcando los topes hacia uno y otro sentido.Also in Figure 3, the threaded stud mounted in the second hole 18 of the regulating ring 8, threaded for this purpose, is referenced with 24. The threaded stud 24 is finished off in the emergent smooth extension 25 which plays in the arcuate groove 21 (see figure 6) referred to, marking the stops in either direction.
En las figuras 8 y 9 se representa en planta y sección, la tuerca de retención 9 del anillo 8. Vemos que está abierta y sus extremos se pueden unir con un tornillo secante 26 (figura 2) . Está roscada interiormente para conectar con el roscado 11 del cuerpo 4 en el que se monta.In figures 8 and 9 the retaining nut 9 of the ring 8 is shown in plan and section. We see that it is open and its ends can be joined with a secant screw 26 (figure 2). It is internally threaded to connect with the threading 11 of the body 4 on which it is mounted.
Por último, en las figuras 13 y 14 se ve el casquillo 3 de adaptación al cañón 2 del arma, estando provisto de rosca exterior 27 e interior 28 adaptadas al cuello 5 del cuerpo 4 y al cañón 2, respectivamente. Finally, in figures 13 and 14, the sleeve 3 of adaptation to the barrel 2 of the weapon is seen, being provided with outer thread 27 and inner 28 adapted to neck 5 of body 4 and barrel 2, respectively.
