Description

Carcasa perfeccionada para fuegos de artificio.Perfect housing for fires artifice.

La presente invención consiste en una carcasa perfeccionada para fuegos de artificio, cuya particular estructura permite ampliar y/o reducir el volumen de la cámara interna que conforma la carcasa para el alojamiento de la carga pirotécnica y por tanto queda facultada para aumentar y/o disminuir la capacidad de su carga pirotécnica, acorde con las necesidades de los efectos pirotécnicos que se pretendan crear en el disparo de fuegos artificiales, todo ello sin necesidad de utilizar carcasas de diferente tamaño, ni cañones de lanzamiento de las carcasas de distinto calibre, ya que aunque aumente la capacidad de carga la carcasa mantiene su mismo diámetro exterior y por tanto permite su lanzamiento por el mismo tubo o cañón lanzador de igual calibre.The present invention consists of a housing perfected for fireworks, whose particular structure allows to expand and / or reduce the volume of the internal chamber that forms the housing for the pyrotechnic load housing and therefore it is empowered to increase and / or decrease the capacity of its pyrotechnic load, according to the needs of the effects pyrotechnics who intend to create in the firing of fires artificial, all without using housings different size, or launch cannons of the carcasses of different caliber, since although the load capacity increases housing maintains its same outer diameter and therefore allows its launch by the same tube or cannon launcher of equal caliber.

La carcasa perfeccionada para fuegos de artificio, objeto de la presente invención, presenta la singularidad de estar conformada por varias piezas huecas obtenidas en cartón prensado con distintas figuras geométricas y por tanto de volúmenes diferentes, las cuales piezas quedan abiertas por una base y/o por las dos bases opuestas, cuyas embocaduras presentan el mismo diámetro para su acoplamiento por los bordes mediante armaduras circulares intermedias que unen el conjunto de piezas.The perfect housing for fires Artifice, object of the present invention, presents the uniqueness of being made up of several hollow pieces obtained in pressed cardboard with different geometric figures and therefore of  different volumes, which pieces are open by a base and / or by the two opposite bases, whose mouths have the same diameter for coupling along the edges by intermediate circular reinforcements that join the set of pieces.

Al menos una de las piezas que va a conformar los extremos de la carcasa, debe presentar moldeada la espoleta para la disposición de una mecha de barreno o pólvora compactada que canaliza el fuego a la cámara interna de la carcasa donde queda alojada la carga pirotécnica.At least one of the pieces that will conform the ends of the housing, must present molded fuze for the disposal of a wick made of bore or compacted powder that channel the fire to the inner chamber of the housing where it remains hosted the pyrotechnic charge.

Asimismo se ha previsto que las armaduras circulares de las distintas piezas de la carcasa, presenten su superficie lateral configurada de forma que ajuste en las embocaduras o bases abiertas de las piezas, estando provistas además dichas armaduras de un apoyo y/o tope exterior para los bordes de dichas piezas en su acoplamiento.It is also planned that the armor circular of the different parts of the housing, present your lateral surface configured to fit the openings or open bases of the pieces, being also provided said reinforcement of a support and / or outer stop for the edges of these pieces in their coupling.

Igualmente la invención ha dispuesto que las armaduras obtenidas en materia plástica, puedan quedar unidas directamente a una o varias piezas de la carcasa, de forma que la armadura pueda ser obtenida en una operación de moldeo sobre la embocadura de la pieza de cartón prensado, o bien una vez moldeadas queden unidas por termosoldadura u otros medios de fijación a dichas piezas para realizar más rápido el montaje de la carcasa.The invention has also provided that armor obtained in plastic, can be joined directly to one or several pieces of the housing, so that the armor can be obtained in a molding operation on the mouthpiece of the pressed cardboard piece, or once molded are joined by heat welding or other fixing means to said parts to perform the assembly of the Case.

En el estado actual de la técnica ya es conocido la obtención de una carcasa en cartón prensado formada por dos mitades semiesféricas que unidas por sus bordes conforman una cavidad o cámara interna donde se aloja la carga pirotécnica.In the current state of the art it is already known obtaining a pressed cardboard housing formed by two hemispherical halves that joined by their edges make up a cavity or internal chamber where the pyrotechnic charge is housed.

Asimismo también es conocido que una de esas dos mitades semiesféricas comporte en su zona polar una cavidad donde se conforma por moldeo una tubuladura o espoleta para la disposición de pólvora compactada o bien de una mecha de barreno de ignición lenta que transmite el fuego al interior de la carcasa para hacer explosionar la carga pirotécnica alojada en su cavidad interna.It is also known that one of those two  hemispherical halves behave in their polar zone a cavity where a pipe or fuze is formed by molding for arrangement of compacted powder or a wick of bore slow ignition that transmits fire inside the housing to explode the pyrotechnic charge lodged in its cavity internal

Las dimensiones de las carcasas, ya sean esféricas o cilíndricas, son las que determinan la capacidad de carga pirotécnica que puede alojarse en su interior, de tal forma que si se desea más carga pirotécnica para crear unos efectos de mayor potencia de fuego, se utilizan unas carcasas de mayor diámetro exterior y por lo tanto con mayor capacidad de carga pirotécnica.The dimensions of the housings, whether spherical or cylindrical, are those that determine the ability to pyrotechnic charge that can be housed inside, in such a way that if more pyrotechnic charge is desired to create effects of greater firepower, larger housings are used outer diameter and therefore with greater load capacity pyrotechnics.

Esta posibilidad de selección de los diámetros de una carcasa también exige la utilización de baterías de cañones lanzadores de distinto calibre para que en su interior se alojen las carcasas que van a ser lanzadas al aire por efecto de la detonación de una carga de disparo y puedan explotar a la altura requerida para producir los efectos pirotécnicos deseados sin crear accidentes entre los espectadores.This possibility of selecting diameters of a housing also requires the use of cannon batteries pitchers of different caliber so that they stay inside the housings that are going to be thrown into the air due to the detonation of a firing charge and may explode at height required to produce the desired pyrotechnic effects without creating accidents among the spectators.

Esta relación existente entre el diámetro exterior de las carcasas y el calibre de los cañones lanzadores exige que para organizar un disparo de fuegos artificiales, el pirotécnico deba disponer de una pluralidad de baterías de cañones lanzadores de distintos calibres para poder disparar todos los tamaños de carcasas seleccionados e impuestos para crear una potencia de fuego deseada, lo que obliga en ocasiones a realizar un transporte oneroso del material de disparo y una perdida de tiempo y energía en la carga de los mismos, que redunda en el coste final del disparo de los fuegos artificiales.This relationship between the diameter exterior of the housings and the caliber of the launching cannons demands that to organize a firework shot, the pyrotechnic must have a plurality of cannon batteries launchers of different calibers to be able to shoot all selected carcass sizes and taxes to create a desired firepower, which sometimes forces a burdensome transport of firing material and a waste of time and energy in their load, which results in the final cost Fireworks shot.

Para paliar este inconveniente la presente invención aporta al mercado la estructura de una carcasa pirotécnica que presenta una variación del volumen de su cámara interna para conseguir diferentes capacidades de carga pirotécnica manteniéndose el mismo diámetro exterior de la carcasa, con lo que se consigue que con una misma batería de cañones de un calibre determinado se disparen carcasas con mayor o menor capacidad de carga pirotécnica, acordes con las necesidades de potencia de fuego requeridas por los profesionales pirotécnicos.To alleviate this problem, the present invention brings to the market the structure of a housing pyrotechnic that presents a variation of the volume of its chamber internal to achieve different pyrotechnic load capacities maintaining the same outer diameter of the housing, which it is achieved that with the same battery of cannons of a caliber certain cases with greater or lesser capacity to shoot pyrotechnic load, according to the needs of firepower required by pyrotechnic professionals.

Para tal efecto, la carcasa perfeccionada para fuegos de artificio se caracteriza porque la carcasa está conformada por una combinación de piezas huecas obtenidas en cartón prensado de distinta configuración externa y dispar volumen, que están abiertas por al menos una base y presentan un diámetro igual en su embocadura de ajuste para quedar unidas en prolongación axial acopladas por sus bordes con la interposición de unos elementos circulares de armado de material plástico situados entre las diferentes partes componentes de la carcasa, con lo que se consigue variar el volumen de la cámara interna de la carcasa y por ende su capacidad de carga pirotécnica sin modificar el calibre de la carcasa ni el de su cañón
lanzador.
