Description

DESCRIÇÃODESCRIPTION

"DISPOSITIVO DO TIPO GUARDA-SOL, COM PELÍCULA TRANSPARENTE OU TRANSLÚCIDA AOS RAIOS SOLARES COM FILTRAGEM DOS RAIOS ULTRAVIOLETAS"" SUNSHINE TYPE DEVICE WITH TRANSPARENT OR TRANSLUCENT FILM TO SOLAR RAYS WITH ULTRAVIOLET RAYS FILTERING "

Trata-se de um dispositivo do tipo guarda-sol que tem a particularidade de deixar passar praticamente toda a luz solar e reter a maior parte dos raios ultravioleta.It is an umbrella-type device that has the peculiarity of letting up virtually all sunlight and retaining most of the ultraviolet rays.

De forma quase paradoxal, não se trata de um guarda-sol no sentido técnico. De facto, o invento não tapa o sol, na aceção de produzir sombra. A utilidade prática do invento radica no facto de o seu utilizador poder estar na praia, apanhar os chamados "banhos de sol", sentir o seu calor e, no entanto, não estar sujeito aos nocivos raios ultravioleta. 0 invento recorre a um filme de pelicula - que vai tomar o lugar do habitual tecido presente nos convencionais guarda-sóis - composto por várias camadas que vão acomodar substâncias já conhecidas por filtrarem ou absorverem os raios solares ultravioletas. 1/5Almost paradoxically, it is not an umbrella in the technical sense. In fact, the invention does not cover the sun, in the sense of producing shade. The practical usefulness of the invention lies in the fact that its user can be on the beach, catch the so-called "sunbathing", feel its heat and yet not be subject to harmful ultraviolet rays. The invention relates to a film film which will take the place of the usual fabric present in conventional umbrellas comprising of several layers which will accommodate substances already known to filter or absorb ultraviolet solar rays. 1/5

Trata-se, no essencial, de aplicar à estrutura convencional de um guarda-sol de praia, na fase de fabrico, em lugar do tecido, um filme de película transparente ou translúcida capaz de absorver os raios ultravioletas e os impedir de chegar a quem se colocar sob a sua proteção permitindo, no entanto, que o seu utente goze do calor do sol.In essence, it is a question of applying to the conventional structure of a beach umbrella, at the stage of manufacture, instead of the fabric, a film of transparent or translucent film capable of absorbing the ultraviolet rays and preventing them from reaching those who if it is placed under its protection allowing, however, that its user enjoys the heat of the sun.

Estado da técnicaState of the art

As películas de filtragem de radiação, ultravioleta e outra, são já conhecidas. 0 inventor desconhece, em absoluto, que alguma espécie de película transparente ou translúcida com caraterísticas de filtro ou de absorção de radiação alguma vez tenha sido aplicada num convencional guarda-sol, em substituição do tecido, permitindo passar a luz solar e o calor mas impedindo a passagem de radiação nociva.Filtrations of radiation, ultraviolet and other, are known. The inventor is not aware at all that some kind of transparent or translucent film with filter or radiation absorption characteristics has ever been applied to a conventional sunshade, replacing the fabric, allowing sunlight to pass through and heat but preventing the passage of harmful radiation.

Naturalmente, a técnica conhece a existência de dispositivos semelhantes com película em plástico. Apresentam, portanto, a mesma caraterística de transparência. Trata-se de vulgares guarda-chuvas. Não têm, naturalmente, nenhuma das caraterísticas no âmbito da proteção contra qualquer espécie de radiação solar. 2/5Of course, the art knows of the existence of similar devices with plastic film. They therefore have the same transparency characteristic. These are vulgar umbrellas. They have, of course, none of the characteristics in the scope of protection against any kind of solar radiation. 2/5

Descrição sumária das figuras A Fig.l representa a película (1) transparente a aplicar na estrutura do guarda-sol; A Fig.2 representa a estrutura de um guarda-sol convencional, já com a película (1) colocada; A Fig. 3 mostra, em pormenor, o corte em alçado do filme (1) apresentando as três camadas que o compõem: as camadas exteriores (1-a) e (1-c) são constituídas por um polietileno e a camada central (1-b) por um co polímero (Etileno Acetato de Vinila), vulgarmente conhecido por EVA.Fig. 1 shows the transparent film (1) to be applied to the umbrella structure; 2 represents the structure of a conventional parasol, already with the film (1) placed; 3 shows in detail the cross-section of the film 1 having the three layers comprising it: the outer layers 1-a and 1-c are composed of a polyethylene and the central layer 1-b) by a copolymer (Ethylene Vinyl Acetate), commonly known as EVA.

Descrição do melhor modo de realização do invento. 0 invento parte de uma estrutura convencional de um guarda-sol (Fig.2). Todavia, em lugar de lhe colocar tecido na fase de fabrico para desempenhar a sua função tradicional -proporcionar sombra - a cobertura é constituída por uma película (1) transparente ou translúcida.Description of the best embodiment of the invention. The invention is part of a conventional structure of an umbrella (Fig. 2). However, instead of placing fabric at the manufacturing stage to perform its traditional function - providing shade - the cover is comprised of a transparent or translucent film (1).

Como representado na Fig.l, a referida película é costurada em gomos, como se de tecido convencional para guarda-sol se tratasse. 3/5As shown in Fig. 1, said film is sewn into buds, as if conventional umbrella fabric was treated. 3/5

Sendo que o objetivo do invento é proporcionar ao utilizador a proteção contra os efeitos nefastos do sol -em sede de radiação ultravioleta - proporcionando, no entanto, que aquele disfrute do sol e respetivo calor, foi necessário substituir o tradicional tecido por um material que tivesse como caraterísticas o facto de filtrar ou absorver os raios solares ultravioletas.The object of the invention is to provide the user with protection against the harmful effects of the sun - in the presence of ultraviolet radiation - while providing that the enjoyment of the sun and its heat, it was necessary to replace the traditional fabric with a material that had as characteristics to filter or absorb the ultraviolet rays.

Existem no mercado vários produtos e substâncias capazes de reduzir significativamente, quer através da filtragem, quer através da absorção, a incidência dos raios solares ultravioleta. A solução foi a utilização de uma película composta por três camadas de polímeros (Fig.3). A dita película é obtida através do processo de co extrusão que combina três camadas de diferentes polímeros num único filme.There are a number of products and substances on the market capable of significantly reducing both the filtration and the absorption of ultraviolet rays. The solution was the use of a film composed of three layers of polymers (Fig. 3). Said film is obtained by the co-extrusion process which combines three layers of different polymers into a single film.

As camadas exteriores (1-a) e (1-c) da película são de polietileno. Este é responsável por evitar a viscosidade da película. A camada central (1 —b) é um co polímero (Etileno Acetato de Vinila), vulgarmente conhecido por EVA e é responsável pela elasticidade e absorção da radiação infravermelha da película. Trata-se de um co polímero há muito conhecido, permitindo uma enorme variedade de aplicações, sendo leve e com elevada conformação (com "efeito memória").The outer layers (1-a) and (1-c) of the film are polyethylene. This is responsible for avoiding the viscosity of the film. The central layer (1-b) is a copolymer (Ethylene Vinyl Acetate), commonly known as EVA and is responsible for the elasticity and absorption of the infrared radiation from the film. It is a well-known co-polymer, allowing a wide variety of applications, being lightweight and highly shaped (with " memory effect ").

Em todas as camadas da película são adicionados aditivos do tipo HALS (Aminas Estericamente Bloqueadas), que são usados como estabilizadores contra a radiação ultravioleta e a absorvem e benzofenona, um dos filtros solares mais utilizados atualmente. A maior ou menor quantidade de aditivos vai determinar a maior ou menor proteção contra a radiação ultravioleta (os chamados "fatores de proteção" já conhecidos dos protetores solares).In all layers of the film are added HALS (Sterically Blocked Amines) type additives, which are used as stabilizers against ultraviolet radiation and absorb it and benzophenone, one of the most commonly used sunscreens today. The greater or lesser amount of additives will determine the greater or lesser protection against ultraviolet radiation (so-called " protection factors " known from the sunscreens).

Tal solução permite que seja possível - na praia e não só -utilizar dispositivos do tipo guarda-sol com diferentes graus ou tipos de proteção, sendo possível, por exemplo, a escolha de um dispositivo com fator de proteção X ou fator Y.Such a solution allows it to be possible - on the beach and not only - to use umbrella-type devices with different degrees or types of protection, for example, being possible to choose a device with protection factor X or factor Y.

Em resultado da aplicação das referidas três camadas na película (1) esta vai apresentar, sumariamente, as seguintes caraterísticas: - Transparência (ou translucidez) que permite a passagem da luz solar e respetivo calor; - Flexibilidade (que favorece a sua confeção e colocação na estrutura do guarda-sol);As a result of the application of said three layers in the film (1) this will summarily present the following characteristics: - Transparency (or translucency) allowing the passage of sunlight and its heat; - Flexibility (which favors its confection and placement in the structure of the umbrella);

Proteção contra a radiação ultravioleta, podendo esta proteção ser mais ou menos intensa.Protection against ultraviolet radiation, this protection may be more or less intense.
