Description
Lama reforzada para persianas y celosías.Reinforced slat for blinds and blinds.
La presente invención se refiere a una lama, de las fabricadas en material termoplástico, como por ejemplo el PVC, que ha sido reforzada mediante un alma metálica para incrementar su resistencia mecánica frente a los agentes medioambientales que ha de soportar.The present invention relates to a slat, of those made of thermoplastic material, such as PVC, which has been reinforced by a metallic soul to increase its mechanical resistance against environmental agents that has of enduring
El objeto de la invención es conseguir una lama altamente resistente, con una participación mínima de material.The object of the invention is to achieve a slat highly resistant, with minimal material participation.
Como es sabido, existen infinidad de perfiles de
lamas de persiana fabricadas en PVC, que adoptan una estructuración
tubular, con tabiques interiores, para conseguir una buena
resistencia mecánica con baja participación del citado material
termoplástico, pero el problema fundamental es que la resistencia a
la carga del viento de estos perfiles es muy reducida, lo que
limita la longitud máxima de los mis-
mos.As is known, there are countless profiles of blind slats made of PVC, which adopt a tubular structure, with internal partitions, to achieve a good mechanical resistance with low participation of said thermoplastic material, but the fundamental problem is that the resistance to wind load of these profiles is very small, which limits the maximum length of the same
mos.
Para lograr una resistencia mayor en estos perfiles de PVC, se hace necesaria la fabricación de los mismos con un espesor de pared notablemente mayor, o lo que es lo mismo, con un incremento considerable en el peso de las mismas, lo que en la práctica trae consigo, en su proceso de fabricación, un elevado consumo energético y una gran cantidad de materia prima, lo que repercute de forma considerable y negativa en los costos de producción.To achieve greater resistance in these PVC profiles, it is necessary to manufacture them with a noticeably greater wall thickness, or what is the same, with a considerable increase in their weight, which in the practice brings, in its manufacturing process, a high energy consumption and a large amount of raw material, which has a considerable and negative impact on the costs of production.
Tratando de obviar este problema es conocido el reforzamiento de perfiles de PVC con la introducción en su seno de hilos continuos termoestables, concretamente de fibra de vidrio, pero los resultados obtenidos resultan insuficientes.Trying to ignore this problem is known on Strengthening of PVC profiles with the introduction of continuous thermosetting wires, specifically fiberglass, but the results obtained are insufficient.
También es conocida la utilización de barras rigidizadoras de diferentes materiales, que se insertan a presión longitudinalmente en el seno de alojamientos operativamente establecidos en el interior de la lama, ya fabricada, pero estas barras complementarias suponen un notable incremento de costos de mano de obra para montaje de las mismas, y tampoco ofrecen las prestaciones mas idóneas debido a su independencia física con respecto al cuerpo de la lama.The use of bars is also known stiffeners of different materials, which are inserted under pressure longitudinally in the housing operationally established inside the slat, already manufactured, but these complementary bars suppose a remarkable increase of costs of labor to assemble them, nor do they offer the more suitable benefits due to their physical independence with regarding the body of the lama.
La lama que la invención propone constituye una solución definitiva al problema citado, de manera que con una participación mínima de material ofrece una máxima resistencia mecánica.The plank that the invention proposes constitutes a definitive solution to the problem cited, so that with a minimum material share offers maximum strength mechanics.
Para ello y de forma más concreta la lama que se preconiza presenta un cuerpo de PVC, con cualquier sección o configuración adecuado a la utilización prevista para la lama en cuestión, cuerpo en cuyo seno se define al menos un alojamiento aplanado para una lámina metálica, con la especial particularidad de que dicha lámina está íntimamente unida al material termoplástico constitutivo de la lama, constituyendo un complemento que se aporta en continuo durante el proceso de extrusión de la misma, es decir que la lámina metálica, preferentemente de aluminio, se aporta a la lama de PVC en el mismo momento en el que ésta se está extruyendo y de forma continua, es decir que dicha lámina de aluminio es de longitud indefinida.For this and in a more concrete way the plank that preconiza presents a PVC body, with any section or configuration appropriate to the intended use for the slat in question, body in which at least one housing is defined flattened for a metal sheet, with the special feature that said sheet is intimately attached to the material thermoplastic constituent of the slat, constituting a complement which is provided continuously during the extrusion process of the same, that is to say that the metallic sheet, preferably of aluminum, it is contributed to the PVC slat at the same time when it is is extruding and continuously, that is to say said sheet of Aluminum is of indefinite length.
Esta íntima unión con carácter monopieza entre
lama y lámina rigidizadora, se potencia mediante la conformación en
dicha lámina metálica de relieves, bajorrelieves y/u orificios, que
al quedar inundados por material termoplástico hacen que la unión
entre ambas piezas sea sólida e inamovible en el
tiempo.This intimate single-piece connection between the slat and stiffener sheet is enhanced by forming in said metallic sheet of reliefs, bas-reliefs and / or holes, which when flooded by thermoplastic material make the union between both pieces solid and immovable in the
weather.
Esta íntima unión entre el PVC y la lámina metálica permite utilizar láminas de espesor muy reducido, con unos óptimos resultados prácticos.This intimate union between the PVC and the sheet metallic allows to use sheets of very reduced thickness, with some Optimum practical results.
Para complementar la descripción que se está realizando y con objeto de ayudar a una mejor comprensión de las características del invento, de acuerdo con un ejemplo preferente de realización práctica del mismo, se acompaña como parte integrante de dicha descripción, un juego de dibujos en donde con carácter ilustrativo y no limitativo, se ha representado lo siguiente:To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:
La figura 1.- Muestra un detalle en sección transversal de una lama reforzada para persianas, celosías y similares, realizada de acuerdo con el objeto de la presente invención.Figure 1.- Shows a detail in section cross section of a reinforced slat for blinds, lattices and similar, carried out in accordance with the purpose of this invention.
La figura 2.- Muestra una vista en perspectiva de la lama de la figura anterior, en que la lama propiamente dicha y refuerzo metálico aparecen seccionados a distinto nivel, para mostrar con mayor claridad las características de éste último.Figure 2.- Shows a perspective view of the plank of the previous figure, in which the plank itself and metal reinforcement are sectioned at different levels, to show more clearly the characteristics of the latter.
En las figuras reseñadas se ha representado una lama de persiana (1), cuyo cuerpo de naturaleza termoplástica, es decir de PVC, se corresponde con la propia referencia (1) y adopta una configuración meramente ejemplaría, a base de una pared frontal y una pared posterior relacionadas mediante tabiques interiores (2), definiendo sobre uno de sus bordes un gancho (3) y en el borde opuesto un receptáculo (4) de embocadura estrangulada, para la unión articulada entre lamas.In the figures outlined, a blind slat (1), whose body of thermoplastic nature, is say of PVC, corresponds to the reference itself (1) and adopts a merely exemplary configuration, based on a front wall and a rear wall related by interior partitions (2), defining on one of its edges a hook (3) and on the edge opposite a receptacle (4) of strangulated mouth, for the articulated union between slats.
No obstante y como acaba de decirse, esta realización no es absoluto limitativa sino que la lama puede adoptar una configuración general semejante a cualquier lama convencional.However, as just said, this realization is not absolute limiting but the lama can adopt a general configuration similar to any plank conventional.
Pues bien, de acuerdo ya con la invención, al menos uno de los tabiques transversales interiores (2) define un alojamiento aplanado para una lámina (5), metálica, preferentemente de aluminio como anteriormente se ha dicho, que queda íntimamente adaptada y fijada al citado alojamiento por cuanto que, como también se ha dicho con anterioridad, la lámina metálica (5) se incorpora a la extrusora de obtención de lama (1) durante el propio proceso de obtención de ésta última, y de forma continua al igual que el material termoplástico constitutivo del cuerpo (1) de la lama.Well, according to the invention, at minus one of the interior transverse partitions (2) defines a flat housing for a sheet (5), metal, preferably of aluminum as previously stated, which remains intimately adapted and fixed to said accommodation because, as It has also been said before, the metal sheet (5) is incorporates the extruder for obtaining slats (1) during the same process of obtaining the latter, and continuously as well that the thermoplastic material constituting the body (1) of the the MA.
Aunque esta unión íntima por construcción podría
ser suficiente para estabilizar convenientemente ambos elementos,
el uno con el otro, se ha previsto que la lámina metálica (5)
incorpore orificios (6), que se observan especialmente en la figura
2 y que como anteriormente se ha dicho pueden ser sustituidos por
relieves, bajorrelieves, etc., de manera que estos orificios (6)
quedan inundados durante el proceso de extrusión con el material
plástico constitutivo del cuerpo (1), definiendo cuellos (7) o
puentes de unión entre los dos tabiques constitutivos del
alojamiento de la pieza metálica, que atraviesan a dicha pieza
metálica inmovilizándola de forma totalmente
defini-
tiva.Although this intimate connection by construction could be sufficient to conveniently stabilize both elements, one with the other, it is provided that the metal sheet (5) incorporates holes (6), which are especially observed in Figure 2 and as previously He has said they can be replaced by reliefs, bas-reliefs, etc., so that these holes (6) are flooded during the extrusion process with the plastic material constituting the body (1), defining necks (7) or connecting bridges between the two partitions constituting the housing of the metal part, which pass through said metal part immobilizing it in a completely defined way
tiva.
Como también se ha dicho con anterioridad, la íntima unión entre el material termoplástico (1) y la lámina metálica (5) permite, manteniendo un espesor de pared del cuerpo (1) de la lama, utilizar láminas de aluminio (5) de reducido espesor, con unos óptimos resultados desde el punto de vista mecánico del conjunto.As also stated previously, the intimate union between the thermoplastic material (1) and the sheet Metallic (5) allows, maintaining a wall thickness of the body (1) of the slat, use aluminum sheets (5) of reduced thickness, with optimal results from the point of view set mechanic.
