Description

"SISTEMA REGULADOR DE PRESSÃO DE DISPARO PARA ARMAS NÃO LETAIS"  "NON-LAWER WEAPON PRESSURE REGULATORY SYSTEM"

Trata a presente solicitação de Patente de Invenção de um inédito "SISTEMA REGULADOR DE PRESSÃO DE DISPARO PARA ARMAS NÃO LETAIS", especialmente de um sistema que calcula e ajusta a pressão de ar comprimido de armas não letais para controle de tumulto tomando como parâmetro a distância versus o alvo, desse modo liberando a pressão adequada para aquela situação. It addresses the present patent application for an unpublished "NON-LAYER WEAPONS", especially a system that calculates and adjusts the air pressure of non-lethal turmoil weapons by taking distance as a parameter. versus the target, thereby releasing the appropriate pressure for that situation.

Segundo Elias (1994), a necessidade de uma sociedade constituir instrumentos de controle para sua proteção conduz à construção de um monopólio de força, centrado na figura do Estado. Este, através de seus agentes, regula a conduta social de maneira uniforme e estável em espaços pacificados, que normalmente estão livres de violência. Ao mesmo tempo em que o Estado protege o indivíduo, força-o a reprimir em si qualquer impulso emocional para cometer violência contra outras pessoas.  According to Elias (1994), the need for a society to constitute control instruments for its protection leads to the construction of a monopoly of force, centered on the state figure. It, through its agents, regulates social conduct in a uniform and stable manner in pacified spaces, which are usually free from violence. At the same time that the state protects the individual, it forces him to suppress within himself any emotional impulse to commit violence against other people.

Nesse sentido, na prática, o Estado deve agir, entre tantas outras situações, em tumultos generalizados em locais públicos ou fechados como, por exemplo, em penitenciárias que por vezes tomam caminhos indesejáveis após a imposição da força e seus armamentos convencionais.  In this sense, in practice, the State must act, among many other situations, in widespread riots in public or closed places, such as in prisons that sometimes take undesirable paths after the imposition of force and its conventional armaments.

Mediante esta realidade, a sociedade em geral e as associações de direitos humanos requerem uma solução para evitar danos e/ ou óbitos às pessoas envolvidas. Por conseguinte, o desenvolvimento de tecnologias voltadas para armas não letais têm surgido como melhor meio de atenuar a gravidade da situação.  Given this reality, society at large and human rights associations require a solution to prevent harm and / or death to the people involved. Therefore, the development of non-lethal weapons technologies has emerged as the best means of mitigating the seriousness of the situation.

Atualmente, as armas não letais para controle de tumultos têm como princípio de funcionamento o ar comprimido ou cartuchos de pólvora com projeteis de borracha. Normalmente, estas armas são do tipo "single shot" ou por repetição. No entanto, apesar da denominação, as armas não letais supracitadas, mediante certos contextos, têm gerado vítimas entre cidadãos civis aí incluindo sérios ferimentos, inclusive óbitos. Tal fato é explicado pelo fato das armas de ar comprimido exercerem pressão de disparo única, de maneira que uma pessoas a cinco metros de distância recebe o mesmo impacto de outra pessoa a cinquenta metros, ou seja, com uma intensidade mui superior, portanto, mais propensa a ser ferida com maior gravidade. Conceitualmente, arma de fogo nada mais é do que um artefato para propulsão de projéteis, por meio de expansão de gases originados na queima controlada de um propelente, mais especificamente a pólvora contida em uma câmara fechada, exceto pelo cano que conduz o projétil. Today's non-lethal riot control weapons have as their working principle compressed air or rubber projectile gun cartridges. Typically, these weapons are of the single shot or repetition type. However, despite the denomination, the aforementioned nonlethal weapons, in certain contexts, have generated casualties among civilian citizens there including serious injuries, including deaths. This is explained by the fact that compressed air guns exert single firing pressure, so that one person at five meters distance receives the same impact from another person at fifty meters, that is, with a much higher intensity, therefore, higher. likely to be severely injured. Conceptually, a firearm is nothing more than an artifact for projectile propulsion, by expanding gases from the controlled burning of a propellant, more specifically the powder contained in a closed chamber, except for the barrel leading the projectile.

O estado da técnica apresenta alguns documentos voltados para dispositivos não letais para controle de tumultos, como o MU 6600494-2 compreende uma arma de defesa e ataque, para uso exclusivo de corporações policiais civis e militares, que trata-se de um bastão cilíndrico confeccionado em madeira de alta resistência dotado em uma extremidade.de uma primeira empunhadura ou ranhuras circulares simétricas e dotado em uma lateral, de uma base hexagonal plana com orifício ou cavidade cilíndrica, onde se acopla perpendicularmente, por introdução, colagem e aparafusamento, a extremidade cilíndrica de diâmetro menor ou pino talhado de um cabo cilíndrico ou segunda empunhadura, confeccionado em madeira de alta resistência e dotado de ranhuras circulares simétricas , constituindo-se dois ângulos retos entre o bastão e cabo, que são revestidos de borracha ou material plástico, ocorrendo o acoplamento descrito do cabo no bastão, na altura correspondente à um quarto do comprimento do bastão e sendo o bastão de defesa e ataque utilizado em tumultos de ruas, em defesa contra todo o tipo de arma branca, nuntchacos e armas de fogo, à curta distância, permitindo que o policial usuário promova impactos com o mesmo, sob alta velocidade, de 600 à 700 quilogramas-força, atuando o bastão em giros de 360°.  The state of the art features some documents aimed at non-lethal riot control devices, such as the MU 6600494-2 comprises a defense and attack weapon for the exclusive use of civil and military police corporations, which is a manufactured cylindrical rod. made of high-strength wood fitted with one end.of a first symmetrical circular grip or grooves and provided on one side with a flat hexagonal base with a bore or cylindrical cavity, where the cylindrical end is coupled perpendicularly by introduction, gluing and screwing smaller diameter or cut-out pin of a cylindrical handle or second handle, made of high-strength wood and fitted with symmetrical circular grooves, consisting of two right angles between the rod and handle, which are coated with rubber or plastic material, described coupling of the cable to the rod at a height corresponding to one quarter of the length the baton being the defensive and offensive baton used in street riots, in defense against all types of melee weapon, nuntchacos and firearms, at close range, allowing the user police officer to make impact with it, under high speed, from 600 to 700 kilograms of force, with the rod acting in 360 ° turns.

Segundo pesquisa realizada do atual estado da técnica, nenhum documento referente a aperfeiçoamentos ou melhoramentos das tecnologias de armas não letais que utilizam ar comprimido como meio propulsor foi localizado.  According to current state-of-the-art research, no document on improvements or improvements to non-lethal weapon technologies using compressed air as a propellant was found.

Ciente do estado da técnica, suas lacunas e inconvenientes, o inventor, pessoa conhecedora do segmento em apreço, após estudos e pesquisas, criou o "SISTEMA REGULADOR DE PRESSÃO DE DISPARO PARA ARMAS NÃO LETAIS" em questão, que por controle computacional calcula e ajusta a liberação da pressão do disparo de intensidade adequada e proporcional à distância do alvo, designada por um dispositivo de aquisição óptica, sonora, a laser ou termal, o que reduz substancialmente os riscos de maiores danos às vítimas.  Aware of the state of the art, its shortcomings and drawbacks, the inventor, who is knowledgeable of the particular segment, has, after studies and research, created the "NON-LEVEL WEAPON PRESSURE REGULATORY SYSTEM" in question, which computes and adjusts by computer control. releasing the firing pressure of appropriate intensity proportional to the target distance, designated by an optical, sound, laser or thermal acquisition device, which substantially reduces the risk of further injury to victims.

Tecnicamente, para operacionalização de determinada arma não letal a ar comprimido, o sistema pleiteado possui um software embarcado com um banco de dados composto pelas pressões de disparo adequadas levando em consideração a distância entre o alvo e a arma, dotada de designador de espaço, seja ele, como já comentado, óptico, sonoro, laser ou termal. De posse das informações, o software envia um sinal para a válvula responsável pela liberação de ar comprimido da arma na intensidade exata para que o projétil chegue até o alvo com a energia potencial suficiente para contê-lo sem maiores danos. Technically, for operation of a certain non-lethal compressed air weapon, the claimed system has software embedded with a data composed by the appropriate firing pressures taking into account the distance between the target and the weapon, provided with space designator, be it, as already commented, optical, sound, laser or thermal. In possession of the information, the software sends a signal to the valve responsible for releasing the gun's compressed air at the exact intensity so that the projectile reaches the target with sufficient potential energy to contain it without further damage.

O "SISTEMA REGULADOR DE PRESSÃO DE DISPARO PARA ARMAS NÃO LETAIS", objeto desta solicitação de Patente de Invenção, consiste essencialmente de um sistema (S) passível de aplicação em qualquer tipo ou modelo de arma (1) não letal a ar comprimido que possui um designador de distância (2) que mede a distância até o alvo (3) e alimenta o banco de dados do software (4) embarcado com a relação das distâncias dos alvos em relação à arma (1) e a pressão de disparo adequada para aquela situação.  The "NON-DETAILED GUN SHOOTING REGULATORY SYSTEM", the subject of this patent application, consists essentially of a system (s) which can be applied to any type or model of non-lethal compressed air weapon (1) having a distance designator (2) that measures the distance to the target (3) and feeds the embedded software database (4) to the ratio of the target distances to the weapon (1) and the appropriate trigger pressure for that situation.

Mais particularmente, o sistema (S) pleiteado a ser aplicado em armas (1) não letais a ar comprimido, se baseia no controle computacional da pressão de disparo graças a um software (4) embarcado dotado de um banco de dados parametrizado pela distância do alvo (3) em relação a arma (1) resultando numa pressão de disparo adequada para aquela situação. Para tanto, a arma (1) apresenta um designador de distância (2) que faz uma telemetria do alvo (3) por tecnologia óptica, sonora, laser ou termal, que conforme o banco de dados supracitado informa ao oscilador (5) a pressão a ser disponibilizada à válvula solenóide (6) que impulsionará o projétil com a intensidade suficiente para não causar maiores danos à vítima, sendo os componentes do referido sistema (S) alimentado por bateria (7) recarregável. More particularly, the system (S) claimed to be applied to non-lethal compressed air weapons (1) is based on the computational control of the firing pressure thanks to an embedded software (4) equipped with a distance parameterized database. target (3) relative to weapon (1) resulting in firing pressure appropriate for that situation. To this end, the weapon (1) has a distance designator (2) that telemetries the target (3) by optical, sound, laser or thermal technology, which according to the above database informs the oscillator (5) the pressure to be provided to the solenoid valve (6) which will propel the projectile with sufficient intensity not to cause further damage to the victim, the components of said system (S) being powered by rechargeable battery (7).

Na prática, operacionalmente, o usuário monta a arma em uma primeira etapa (E1), para numa segunda etapa (E2) ativar o designador de distância. Na terceira etapa (E3) o atirador aponta a arma para o alvo para que o referido designador depare com o alvo. Na quarta etapa (E4) o designador faz a leitura do alvo em relação a arma e envia essa informação para o software. Numa quinta etapa (E5) tal informação é avaliada, desde que não seja inferior a cinco metros ou superior a cem metros, capta no banco de dados a pressão requerida para aquela distância acionando o oscilador/ válvula solenóide.  In practice, operationally, the user assembles the weapon in a first step (E1), to in a second step (E2) activate the distance designator. In the third stage (E3) the shooter points the weapon at the target so that said designator encounters the target. In the fourth step (E4) the designator reads the target against the weapon and sends this information to the software. In a fifth step (E5) such information is evaluated, provided it is not less than five meters or more than one hundred meters, it captures in the database the pressure required for that distance by operating the oscillator / solenoid valve.

Portanto, o presente sistema (S) propõe recursos absolutamente novos para controle da pressão para armas não letais a ar comprimido via software, designador de distância e oscilador/ válvula solenóide, promovendo uma solução para os efeitos negativos e indesejados das armas convencionais já fartamente expostos, portanto sendo merecedor desse pedido de privilégio de patente de invenção.  Therefore, the present system (S) proposes absolutely new pressure control capabilities for non-lethal compressed air weapons via software, distance designator and solenoid valve / oscillator, providing a solution to the negative and unwanted effects of conventional weapons already heavily exposed. therefore meriting such patent application.
