Various forms of entertainment displacement are known in the art, the simplest being skateboarding, as already mentioned, and the most sophisticated are levitation systems on a specially prepared surface.
[0003]Estes sistemas de levitação em uma superfície preparada para este fim compreende uma prancha capaz de se elevar por meio de um campo magnético e se deslocar linearmente através de uma fonte propulsora externa. No entanto, essa construção apresenta uma série de inconvenientes e desvantagens, sendo o maior dele o fato de demandar um terreno previamente preparado com ligas que geram campos magnéticos, como por exemplo, imãs. Em outras formas construtivas, há necessidade que a prancha que se elevará contenha materiais semicondutores que dependem de sistemas de refrigeração para que em combinação com a superfície previamente preparada seja elevado.  These levitation systems on a surface prepared for this purpose comprise a board capable of elevating by means of a magnetic field and moving linearly through an external propelling source. However, this construction has a number of drawbacks and drawbacks, the biggest one being that it requires previously prepared terrain with alloys that generate magnetic fields, such as magnets. In other constructive forms, the rising board needs to contain semiconductor materials that depend on cooling systems so that in combination with the previously prepared surface it is raised.
[0004]Nesta última forma de construção mencionada, os semicondutores empregados são muito caros e seus recipientes devem ser blindados, o que gera um alto custo e complexibilidade tanto para a construção como na manutenção do referido dispositivo.  In the latter mentioned construction, the semiconductors employed are very expensive and their containers must be shielded, which generates a high cost and complexity for both the construction and maintenance of said device.

[0008]Estas e outras vantagens e benefícios acima citados são alcançados pela provisão de um dispositivo de deslocamento aéreo, composto por um corpo, maciço ou não, o qual tem formato de uma prancha ou outra geometria conhecida e adequada, sendo que dita prancha comporta próximo as suas porções marginal dois orifícios que recebem um meio de elevação e propulsão através de um sistema de hélices ou turbinas, que em um primeiro ciclo de trabalho elevam o dispositivo em relação ao solo a uma distância preestabelecida, em ato contínuo para obter o deslocamento em trajetória linear, provendo a flutuação da prancha e consequentemente de seu usuário. These and other advantages and benefits mentioned above are attained by the provision of an air displacement device consisting of a body, solid or not, which has the shape of a board or other known and suitable geometry, said board having near its marginal portions two holes that receive a means of lifting and propulsion through a system of propellers or turbines, which in a first cycle of work raise the device from the ground to a predetermined distance, continuously to obtain displacement. in linear trajectory, providing the fluctuation of the board and consequently of its user.
[0009]De acordo com a invenção ora proposta, as turbinas ou hélices recebem transmissão mecânica de uma árvore de transmissão de força. Dita árvore obtém um fluxo de transmissão através de uma fonte motora, que pode ser um ou mais motores a bateria ou a combustão, ramificando dito fluxo de força de modo a imprimir movimento nas hélices ou turbinas e prover o empuxo e a propulsão do dispositivo.  According to the proposed invention, turbines or propellers receive mechanical transmission from a power transmission tree. Said tree obtains a transmission flow through a motor source, which may be one or more battery or combustion engines, branching said force flow so as to imprint movement on the propellers or turbines and provide thrust and propulsion of the device.

Uma vez ramificado o fluxo de transmissão de força mecânica, os eixos se acoplam as hélices ou turbinas (04) instaladas no perímetro dos orifícios (02A-02B). Os eixos movidos (03B-03C) operativamente associados às hélices ou turbinas (04), em estágio de trabalho passam a imprimir movimento às mesmas, de forma que em um primeiro ciclo de trabalho as hélices ou turbinas (04) elevam o dispositivo sobre o solo em uma distância pré-determinada pelo usuário. Em ato contínuo passa a ocorrer o deslocamento através do posicionamento das pás das hélices ou turbinas (04) em ângulo relativo a direção que o usuário quer se deslocar. Joining shafts to receive the flow of mechanical force can be by means of crown and pinion or other form known and suitable for this purpose, such as contact gears or couplings. Once the mechanical force transmission flow is branched, the shafts engage the propellers or turbines (04) installed at the perimeter of the holes (02A-02B). The driven shafts (03B-03C) operatively associated with the propellers or turbines (04), in working stage, start to move them, so that in a first working cycle the propellers or turbines (04) lift the device over the ground at a distance predetermined by the user. In a continuous act, the displacement by positioning the propeller or turbine blades (04) at an angle relative to the direction the user wants to travel.

Ditos impelidores em estágio de trabalho admitem o ar da atmosfera através dos orifícios (02A-02B) e provê a elevação e o deslocamento do dispositivo, sendo que a elevação se dá pelo deslocamento de ar gerado pelas hélices ou turbinas (04). A posição das hélices ou turbinas (04) é ajustada através de um motor de passo (não representado), dito motor de passo ou servos motores está associado a controles eletronicos que permitem o ajuste fino da posição do eixo das hélices ou turbinas no plano angular.  [0015] Elevation and displacement take place through the constant impellers of the propellers or turbines (4). Said impellers at work stage admit the air of the atmosphere through the holes (02A-02B) and provide the elevation and displacement of the device, and the elevation occurs by the displacement of air generated by the propellers or turbines (04). The position of the propellers or turbines (04) is adjusted by a stepper motor (not shown), said stepper motor or servo motors is associated with electronic controls that allow fine adjustment of the position of the propeller or turbine shaft in the angular plane. .
[0016]O controle da rotação dos motores de passo ou servo motores se dá através de um algoritmo associado a uma interface de controle que pode ser um botão, pedal ou qualquer forma de controle remoto com ou sem fios, inclusive joysticks, de forma que ao acioná-lo a direção de curso do dispositivo é alterada pela forma de admissão do ar nas pás das hélices ou turbinas (04).  Stepper or servo motor rotation is controlled by an algorithm associated with a control interface that can be a button, pedal or any form of wired or wireless remote control, including joysticks, so that When it is activated, the direction of travel of the device is altered by the air intake to the propeller or turbine blades (04).
[0017]O algoritmo acima descrito conta ainda com informações obtidas através de sensores ou transdutores eletronicos de modo à sensorizar parâmetros como: altura do dispositivo em relação ao solo, velocidade de cruzeiro, deslocamento do corpo do usuário, autonomia entre outras que provêm ao usuário melhor dirigibilidade ao dispositivo e respostas mais rápidas aos comandos.  The algorithm described above also has information obtained through sensors or electronic transducers in order to sensing parameters such as: height of the device in relation to the ground, cruising speed, displacement of the user's body, autonomy among others that provide the user. better device handling and faster response to commands.
[0018]Estas informações são obtidas pelos sensores, enviadas a um processador de dados ou microcontrolador, que provê sua gestão. Sendo que em alguns casos o algoritmo pode gerencia-las de maneira automatizadas, como por exemplo, informações obtidas por meio sensores de distância podem ser geridas pelo processador de dados, de modo a que se reduza a velocidade de cruzeiro do dispositivo na eminência de choque com algum obstáculo.  This information is obtained by the sensors, sent to a data processor or microcontroller, which provides its management. Since in some cases the algorithm can manage them in an automated manner, for example, information obtained by means of distance sensors can be managed by the data processor, so that the device's cruising speed at shock imminence is reduced. with some obstacle.
[0019]Tendo descrita a configuração preferencial, fica claro que eventuais mudanças podem ocorrer como, por exemplo, nos componentes empregados em sua construção e nas formas de interface com o usuário sem que, contudo fuja do escopo das reivindicações que acompanham o presente relatório descritivo.  Having described the preferred embodiment, it is clear that any changes may occur such as, for example, the components employed in its construction and user interface forms without, however, departing from the scope of the claims accompanying this specification. .
