[002] The present utility model refers to a constructive arrangement introduced into a projector for projection of images having ornamental purpose.
[003] O projetor de acordo com o presente modelo de utilidade se caracteriza por possuir fonte de luz interna distanciada do centro do projetor para melhor visualização da projeção das imagens. [003] The projector according to the present utility model is characterized by having an internal light source distanced from the center of the projector for better visualization of the projection of the images.
Estado da técnica State of the art
[004] São conhecidas do estado da técnica diversas configurações de projetores da natureza descrita acima. Various projector configurations of the nature described above are known from the state of the art.
[005] Um exemplo é a solução revelada pelo documento patentário US 8,462,079 que se refere a um "Aparato, sistema e método ornamentar. Dito documento patentário trata de um sistema, aparelho e método ornamental que é dinamicamente modificável. As modalidades do sistema ornamental compreendem um processador, pelo menos um membro ornamental e um controlador de dados. O processador é um computador ou dispositivo semelhante que armazena dados para transmissão. O membro ornamental é configurado para receber e exibir dados armazenados em um banco de dados. As modalidades da presente invenção podem ser acopladas a outros sistemas ornamentais através de uma rede de área alargada, em que os usuários podem compartilhar arquivos de dados para exibição (conforme contido no resumo do documento patentário). [005] An example is the solution disclosed by the patent document US 8,462,079 which refers to an "apparatus, system and method of ornamentation." The invention relates to an ornamental system, apparatus and method which is dynamically modifiable. a processor, at least one ornamental member, and a data controller The processor is a computer or similar device that stores data for transmission The ornamental member is configured to receive and display data stored in a database The embodiments of the present invention can be coupled to other ornamental systems over a wide area network, where users can share data files for display (as contained in the patent document summary).
[006] Como é possível deduzir a partir do documento patentário US 8,462,079, a disposição divulgada por ele exige uma grande sofisticação, uma vez que admite recebimento de informações externas por meio de rede de área alargada. Além disso, outra desvantagem é o uso das [006] As can be deduced from patent document US 8,462,079, the disclosure disclosed by it requires a great sophistication, since it admits receipt of external information through wide area network. In addition, another disadvantage is the use of
FOLHAS DE SUBSTITUIÇÃO (REGRA 26) projeções que fica extremamente limitado, uma vez que o aparato visa projetar imagens ao seu próprio corpo, ou, em uma modalidade alternativa, admite adição de partes como lentes e semelhantes para projeção em superfícies externas como paredes e teto de um cómodo. Consequentemente, o método e os aparatos providos por US 8,462,079 possuem custos mais elevados, tendo em mente limitações como as acima dispostas. REPLACEMENT SHEETS (RULE 26) projections that is extremely limited, since the apparatus aims to project images to its own body, or, in an alternative modality, admits addition of parts like lenses and the like for projection on external surfaces like walls and ceiling of a comfortable one. Accordingly, the method and apparatuses provided by US 8,462,079 have higher costs, bearing in mind limitations such as those set forth above.
[007] Outros dispositivos do estado da técnica são aqueles apresentados pelos documentos patentários US 2006/0291237, US 2014/0218926, US 6,439,723 e US 8,398,270. Contudo, ditas solução persistem exibindo como principais problemas ou a exigência de um aparato mais sofisticado, e, portanto, mais dispendioso, para conseguir projetar imagens com a devida clareza; ou a ineficiência de disposições mais simples, e consequentemente menos dispendiosas, em projetar imagens com clareza e tendo apenas as sombras necessárias para a boa visualização pretendida. Other prior art devices are those disclosed in patent documents US 2006/0291237, US 2014/0218926, US 6,439,723 and US 8,398,270. However, such a solution remains to be seen as the main problems or the requirement of a more sophisticated, and therefore more expensive, device to be able to project images with clarity; or the inefficiency of simpler, and consequently less costly, provisions in designing images clearly and having only the shadows necessary for proper viewing.
[008] Existe, portanto, espaço para uma disposição construtiva introduzida em projetor integrando as seguintes características: There is, therefore, space for a constructive arrangement introduced in a projector integrating the following characteristics:
a) construção fácil e de custo baixo; e a) easy and low cost construction; and
b) projeção nítida em uma superfície externa ao próprio objeto. b) clear projection on a surface external to the object itself.

Descrição detalhada do modelo de utilidade Detailed description of utility model
[01 1 ] O projetor (100) de acordo com o modelo de utilidade compreende parede frontal (1 10), duas paredes laterais (120, 130), base (140), teto (150) e parede posterior (160). No interior do projetor (100) estão dispostas uma plataforma (200) e uma fonte de luz (300) que se encontra na plataforma (200). The projector 100 according to the utility model comprises front wall 110, two side walls 120, 130, base 140, ceiling 150 and back wall 160. A platform (200) and a light source (300) located on the platform (200) are disposed inside the projector (100).
[012] A fim de melhor visualizar o interior do projetor (100), ele se encontra representado sem uma das paredes laterais (120) na figura 1 . [012] In order to better visualize the interior of the projector 100, it is shown without one of the side walls 120 in Figure 1.
[013] A parede frontal (1 10), as paredes laterais (120, 130), a base (140), o teto (150) e a parede posterior (160) do projetor (100) são fixados entre si formando um objeto tridimensional, sendo que as paredes laterais (120, The front wall 110, the sidewalls 120, 130, the base 140, the ceiling 150 and the back wall 160 of the projector 100 are secured together to form an object dimensional, the side walls (120,
FOLHAS DE SUBSTITUIÇÃO (REGRA 26) 130), o teto (150) e a parede posterior (160) podem ou não possuir mesma espessura que a parede frontal (1 10) e a base (140). REPLACEMENT SHEETS (RULE 26) 130, the ceiling 150 and the back wall 160 may or may not have the same thickness as the front wall 110 and the base 140.
[014] Pelo menos a parede frontal (1 10) e eventualmente uma ou mais das paredes laterais (120, 130), base (140), teto (150) e parede posterior (160) do projetor (100) dispõe de desenhos (1 15) compostos por orifícios formados por corte ou recorte ou estampagem ou similar (não ilustrados para melhor visualização do projetor (100)) com finalidade ornamental, através dos quais passa parte do feixe de luz (não mostrado) emitido pela fonte de luz (300). At least the front wall 110 and optionally one or more of the side walls 120, 130, the base 140, the ceiling 150 and the back wall 160 of the projector 100 are provided with drawings 15) composed of cut-or-cut holes or embossing or the like (not shown for better viewing of the projector 100) with ornamental purpose, through which part of the light beam (not shown) emitted by the light source ( 300).
[015] O presente modelo de utilidade prevê que o desenho (1 15), por exemplo, da parede frontal (1 10) possa estar espelhado para que a luz que passa através dele componha uma projeção não espelhada na superfície desejada. The utility model foresees that the design 115, for example, of the front wall 110 may be mirrored so that the light passing therethrough composes an unexposed projection on the desired surface.
[016] No presente modelo de utilidade (e diferente de diversas outras soluções do estado da técnica) a fim de prover uma iluminação que produza uma projeção de maior nitidez ao passar pelos orifícios da parede frontal (1 10), além de ser pontual, a fonte de luz (300) se encontra disposta na plataforma (200) para que dita fonte de luz (300) esteja recuada em relação ao centro do projetor (100) e elevada em relação à base (140). [016] In the present utility model (and different from several other solutions of the prior art) in order to provide an illumination which produces a more distinct projection as it passes through the orifices of the front wall (10), in addition to being punctual, the light source 300 is disposed on the platform 200 so that said light source 300 is recessed relative to the center of the projector 100 and raised relative to the base 140.
[017] Dita fonte de luz (300) pode ser uma dentre LED, OLED, LED em miniatura, LED bicolor, LED tricolor, LED de alto brilho, dentre outros e sem se restringir a uma dessas opções. [017] Said light source (300) may be one of LED, OLED, miniature LED, bi-color LED, tricolor LED, high-brightness LED, among others and without being restricted to one of these options.
[018] A distância (d) da fonte de luz (300) para a parede frontal (1 10) corresponde a entre 52% e 98% da distância total entre a parede frontal (1 10) e a parede posterior (160). Esses valores são os mesmos quando temos como referência a distância entre o teto (150) e a base (140) do projetor (100), em que a distância (d) da fonte de luz (300) para o teto (150) também é de 52% a 98% da distância total entre o teto (150) e a base (140). The distance d of the light source 300 to the front wall 110 corresponds to between 52% and 98% of the total distance between the front wall 110 and the back wall 160. These values are the same when referring to the distance between the ceiling 150 and the base 140 of the projector 100, wherein the distance d from the light source 300 to the ceiling 150 is from 52% to 98% of the total distance between the ceiling (150) and the base (140).
FOLHAS DE SUBSTITUIÇÃO (REGRA 26) [019] A plataforma (200) é construída de tal modo que a fonte de luz (300) possua uma inclinação em relação ao plano horizontal, de modo que o eixo longitudinal ascendente da fonte de luz (300) - perpendicular à rampa inclinada (210) da plataforma (200) - forma um ângulo (a) entre 30Q e 89Q, preferencialmente 60Q com o plano horizontal. REPLACEMENT SHEETS (RULE 26) The platform 200 is constructed in such a way that the light source 300 has an inclination relative to the horizontal plane, so that the upward longitudinal axis of the light source 300 - perpendicular to the inclined ramp 210 of the platform 200 forms an angle (a) between 30 Q and 89 Q , preferably 60 Q with the horizontal plane.
[020] É de se notar que a angulação permite que luz projetada pela fonte de luz (300) não esteja apontada diretamente para a região das mensagens, o que deformaria a imagem projetada. [020] It is to be noted that the angulation allows light projected by the light source 300 not to be pointed directly into the message region, which would deform the projected image.
[021 ] Da mesma maneira, a distância (d) acima disposta, em adição às possíveis angulações da fonte de luz (300) com as paredes do projetor (100) mitiga a difusão da luz e evita que as letras ou imagens projetadas sofram influência negativa da espessura das paredes do objeto, o que prejudicaria a nitidez e clareza do desenho (1 15) projetado. In the same way, the distance (d) above, in addition to the possible angles of the light source (300) with the walls of the projector (100) mitigates the diffusion of light and prevents the projected letters or images from being influenced negative effect of the thickness of the object walls, which would impair the sharpness and clarity of the designed design.
[022] O versado na técnica compreenderá que, para que a projeção dos desenhos (1 15) de qualquer uma das paredes do projetor (100), incluindo a parede frontal (1 10), as paredes laterais (120, 130), a base (140), o teto (150) e a parede posterior (160), se desse de maneira perfeita, seria preciso ter ou uma distância tendendo ao infinito ou uma espessura destas paredes tendendo a zero. Dado que estas duas situações são inviáveis, a luz, ao passar pelos desenhos (1 15), sofre interferência do ângulo entre a posição da fonte de luz (300) e a normal dos desenhos (1 15). Esta angulação gera uma nova secção por onde a luz passa, e que modifica a forma da secção dos desenhos (1 15), deformando a projeção e podendo descaracterizar os desenhos (1 15) das paredes do projetor (100). One skilled in the art will appreciate that, in order that the projection of the designs 115 from any one of the walls of the projector 100, including the front wall 110, the side walls 120, 130, (140), the ceiling (150) and the back wall (160), if provided in a perfect manner, it would be necessary to have either a distance tending to infinity or a thickness of these walls tending to zero. Since these two situations are infeasible, the light, upon passing through the drawings (15), undergoes interference from the angle between the position of the light source (300) and the normal one of the drawings (15). This angulation generates a new section through which the light passes, and which modifies the shape of the section of the drawings (1 15), deforming the projection and being able to de-characterize the designs (15) from the walls of the projector (100).
[023] A fim de amenizar este problema é que a fonte de luz (300) do projetor (100) de acordo com o presente modelo de utilidade é posicionada o mais distante possível dos lados que se pretende projetar, para que a projeção tenha a melhor qualidade de projeção possível dentro das dimensões do projetor (100). In order to alleviate this problem is that the light source 300 of the projector 100 according to the present utility model is positioned as far as possible from the sides to be projected so that the projection has the the best possible projection quality within the dimensions of the projector (100).
FOLHAS DE SUBSTITUIÇÃO (REGRA 26) [024] Além disso, o projetor (100) de acordo com o presente modelo de utilidade dispensa uso de acessórios adicionais, lentes, projetores, processadores e outros dispositivos de ampliação das imagens. Assim, reduz ainda mais o custo de fabricação e torna sua construção ainda mais simples. REPLACEMENT SHEETS (RULE 26) In addition, the projector 100 according to the present utility model dispenses with the use of additional accessories, lenses, projectors, processors and other image enlargement devices. This further reduces manufacturing cost and makes construction even simpler.
Considerações finais Final considerations
[025] É evidente que as medidas e relações entre medidas descritas para a presente disposição construtiva podem variar de acordo com o dimensionamento do projetor (100). [025] It is evident that the measures and relationships between measures described for the present constructive arrangement may vary according to the design of the projector (100).
[026] Exaustivos testes práticos, porém, demonstraram que as referidas dimensões e suas relações são altamente eficientes e eficazes na projeção e iluminação providas pelo projetor. [026] Exhaustive practical tests, however, have demonstrated that these dimensions and their relationships are highly efficient and effective in the projection and illumination provided by the projector.
[027] Além disso, a disposição construtiva do presente modelo de utilidade e as referidas medidas e suas relações, são altamente confiáveis e reproduzíveis. [027] In addition, the constructive disposition of the present utility model and the said measures and their relations, are highly reliable and reproducible.
Conclusão Conclusion
[028] Como pode ser inferido a partir da descrição acima, a disposição construtiva de acordo com o presente modelo de utilidade supera as soluções do estado da técnica, sendo um objeto de uso prático, perfeitamente suscetível de aplicação industrial, que apresenta nova disposição, envolvendo ato inventivo e resultando em melhoria funcional no seu uso. [028] As can be inferred from the above description, the constructive arrangement according to the present utility model overcomes the solutions of the state of the art, being an object of practical use, perfectly susceptible of industrial application, which presents a new arrangement, involving inventive act and resulting in functional improvement in its use.
