CAMPO DE LA INVENCIÓN. FIELD OF INVENTION.
La presente invención se refiere a un ensamble de placas con diferentes materiales (panel sándwich) que compone un panel balístico estructurado en combinación con un mecanismo amortiguador (a doble efecto) retractable que permite al panel anti esquirlas ( spall liner ) efectuar un movimiento limitado atrás, empujado por un proyectil que perforo la placa frontal en acero y/o aluminio. The present invention refers to an assembly of plates with different materials (sandwich panel) that makes up a ballistic panel structured in combination with a retractable (double-acting) shock-absorbing mechanism that allows the anti-splinter panel (spall liner) to carry out a limited movement backwards, pushed by a projectile that pierced the front plate in steel and/or aluminum.
Particularmente y en detalle, se refiere a un ensamble del panel que comprende un mecanismo miembro compresible (resorte) sujeto a un eje central de apoyo, el cual atraviesa completamente el panel balístico para transformar la energía cinética del proyectil en energía absorbida en primera parte por el movimiento de retroceso momentáneo del panel anti esquirlas y segundo lugar, por la capacidad de elongación/deformación con o sin perforación de algunas capas de telas del mismo panel anti esquirlas (spall liner). Lo que permite frenar, absorber y disipar mejor la energía residual del proyectil. Particularly and in detail, it refers to a panel assembly that comprises a compressible member mechanism (spring) attached to a central support axis, which completely crosses the ballistic panel to transform the kinetic energy of the projectile into energy absorbed in the first part by the momentary recoil movement of the anti-splinter panel and secondly, by the elongation/deformation capacity with or without perforation of some layers of fabrics of the same anti-splinter panel (spall liner).

Among other advantages, the present invention allows it to be used in a general way in the manufacture of composite plates with extended structural properties, comprehensively increasing safety for the use of protection against projectile impacts or fragments of mine and/or artillery explosions, especially in vehicles. military troop carriers, law enforcement and/or large civilian vehicles.
ANTECEDENTES DE LA INVENCIÓN. BACKGROUND OF THE INVENTION.
La problemática actual es la creación de sistemas de protección más liviano principalmente para los vehículos militares de transporte de personal, para protegerlos contra proyectiles perforantes y fragmentos de explosiones con una reducción sustancial del peso total del vehículo con el propósito aumentar su versatilidad y su autonomía y sobrevivencia en operación. La solución inicial fue la utilización de placas de acero de alta dureza generalmente 450/500 brinell). No obstante, esta solución es pesada limitando la buena movilidad del vehículo en operaciones. Los sistemas de resortes aplicados a panel balísticos son conocidos en la técnica. Un ejemplo de ello se referencia en la solicitud pct WO2014149087 de pepka, que describe un conjunto de blindaje que incluye un panel, una placa base y un resorte acoplado entre el panel de blindaje y la placa de base. Este desarrollo esta encaminado a absorber una explosión de impacto o proyectil que golpeará el conjunto de blindaje y desviará el panel de blindaje y el resorte. El resorte y el panel de blindaje absorben suficiente energía de la explosión de impacto o proyectil para evitar daños a las estructuras subyacentes. El resorte puede ser sólido que tenga un coeficiente deseado para proteger contra una determinada carga de impacto. Este desarrollo sólo define una configuración de disposición entre el panel de blindaje y la placa base. The current problem is the creation of lighter protection systems mainly for military personnel carriers, to protect them against armor-piercing projectiles and fragments of explosions with a substantial reduction in the total weight of the vehicle with the purpose of increasing its versatility and autonomy and survival in operation. The initial solution was the use of high hardness steel plates, generally 450/500 brinell). However, this solution is cumbersome, limiting the good mobility of the vehicle in operations. Ballistic panel applied spring systems are known in the art. An example of this is referenced in pepka pct application WO2014149087, which describes a shield assembly including a panel, a base plate and a spring coupled between the shield panel and the base plate. This development is aimed at absorbing an impact or projectile blast that will hit the armor assembly and deflect the armor panel and spring. The spring and armor panel absorb enough energy from the impact or projectile blast to prevent damage to underlying structures. The spring may be solid having a desired coefficient to protect against a given impact load. This development only defines a layout configuration between the shield panel and the base plate.
Otros desarrollos con sistemas de panel protector basado en sistemas de amortiguación sobre paneles balísticos se definen en la patente de estados unidos US4004493 de costanza, que presenta una lámina curvada a prueba de balas que consta de una capa blindada entre una capa interior de tela de nailon y una capa de material acolchado exterior, donde la capa blindada consta de un conjunto de pequeñas placas de metal dobladas en forma de u o en forma de n y sujetadas juntas por pequeños anillos para formar un panel flexible que permite al usuario mover cómodamente su cuerpo mientras las placas de metal resisten la penetración de una bala debido a un diseño novedoso en el que se utiliza la elasticidad de las mismas para resistir la bala. Este desarrollo no está encaminado a protección contra fragmentos metálicos de explosiones. Other developments with protective panel systems based on ballistic panel damping systems are defined in United States patent US4004493 de Costanza, which presents a curved bulletproof sheet consisting of an armored layer sandwiched between an inner layer of nylon fabric and an outer layer of padding material, where the armor layer consists of a set of small metal plates bent into a u-shape or an n-shape and held together by small rings to form a flexible panel that allows the wearer to comfortably move their body while wearing them. Metal plates resist penetration by a bullet due to a novel design that uses the elasticity of the plates to resist the bullet. This development is not aimed at protection against metal fragments from explosions.
Por tanto, la técnica actual aun cuando evidencia mecanismos amortiguadores fijados sobre los paneles balísticos compuesto de placas de acero y/o aluminio, no ha establecido una configuración eficaz que incluya la adjunción de un panel anti esquirlas (spall liner) estructurado con telas tejidas y no tejidas con fibras naturales, sintéticas, poliméricas y/o minerales, aumentando la resistencia gracias a la capacidad de movimiento de una parte de la superficie del panel anti esquirlas (spall liner) detrás de una placa de metal de muy alta dureza perforado por cualquier tipo de proyectil, fijado con un mecanismo retractable que conforma la carrocería, las puertas, bajo el chasis y techo de cualquier tipo de vehículo que aumenta la capacidad de resistir a los proyectiles, fragmentos metálicos de explosiones de minas terrestres y de bombas de artillería, perforando la placa metálica externa , aumentando la sobrevivencia del personal dentro de cualquier tipo de vehículo. Therefore, the current technique, even when it shows shock-absorbing mechanisms fixed on the ballistic panels composed of steel and/or aluminum plates, has not established an effective configuration that includes the addition of an anti-splinter panel (spall liner) structured with woven fabrics and non-woven with natural, synthetic, polymeric and/or mineral fibers, increasing resistance thanks to the movement capacity of a part of the surface of the anti-splinter panel (spall liner) behind a very high hardness metal plate perforated by any type of projectile, fixed with a retractable mechanism that forms the body, doors, under the chassis and roof of any type of vehicle that increases the ability to resist projectiles, metal fragments from landmine explosions and artillery bombs, perforating the external metal plate, increasing the survival of the personnel inside any type of vehicle.

Después que un proyectil perforo la parte metálica del panel sándwich fijado bajo el chasis. La presente invención ofrece una solución de protección balística con mayor resistencia a impactos de balas y fragmentos de explosiones, para el uso principalmente en vehículos militares, seguridad, policial, transporte de valores y vehículos vip. De acuerdo con ello, se proporciona una aumentación substancial de la capacidad de resistencia balística del panel anti esquirlas, compuesto de telas tejidas y no tejidas con fibras naturales, sintéticas, poliméricas y/o minerales; el cual está fijado con un mecanismo amortiguador retractable. Cuando un proyectil perfora la placa metálica (acero y/o aluminio), empujando el panel anti esquirlas (spall liner) hacia atrás, frenando así el proyectil, entonces acción complementaria a la elongación/deformación del panel anti esquirlas que permite absorber la energía del proyectil y/o de un fragmento de metal que se despegó de la placa frontal. La resistencia balística del panel anti esquirlas es aumentada por la capacidad de un movimiento limitado hacia atrás gracias al mecanismo amortiguador retractable, el cual panel o parte del panel regresa a su posición inicial después de la disipación de la energía y hasta la detención del proyectil dentro de las capas de telas del panel. The object of the present invention is a structured ballistic panel composite of reduced weight in combination with a retractable mechanism that can be fixed under the chassis and behind the ballistic steel/aluminum plates that form the structure of a body, increasing the capacity to resist to land mine explosions and increases the ballistic resistance of any type of vehicle. After a projectile pierced the metal part of the sandwich panel fixed under the chassis. The present invention offers a ballistic protection solution with greater resistance to bullet impacts and explosion fragments, for use mainly in military vehicles, security, police, value transport and VIP vehicles. Accordingly, a substantial increase in the ballistic resistance capacity of the anti-splinter panel, composed of woven and non-woven fabrics with natural, synthetic, polymeric and/or mineral fibers, is provided; which is fixed with a retractable damping mechanism.
