Description
LAMAS CON ABERTURAS REGULABLES PARA PERSIANAS Sector de la técnica LAMAS WITH REGULABLE OPENINGS FOR BLINDS Technical sector
la invención se encuadra en el sector de la construcción, concretamente en el campo de la fabricación de sistemas de oscurecimiento. Estado de la Técnica The invention falls within the construction sector, specifically in the field of dimming systems manufacturing. State of the Art
En la actualidad, se conocen distintos sistemas de persianas enrollables formadas por un conjunto de lamas horizontales separadas por unas guías más bajas y estrechas, realizadas en la parte superior de las mismas, que se alojan en una muesca inferior, y que permiten articularlas y enrollar todo el paño en el interior del capialzado. Estas lamas, por lo general de plástico o metálicas, son planas y opacas en la mayoría de los casos, discurriendo por unas guías vertica
les ubicadas habitualmente en los laterales. En algunos sistemas, las lamas principales son independientes y orienta bies, careciendo del sistema de conexión descrito anteriormente. Su precio de mercado es bastante más elevado que el convencional y requieren además de accionamiento mecánico con alimentación eléctrica. las lamas más pequeñas y estrechas, que enlazan y articulan las principales, no son opacas y normalmente están perforadas con pequeñas ranuras que, en teoría, permitirían el paso del aire y la luz. Sin embargo, sus reducidas dimensiones, no suelen alcanzar el centímetro cuadrado, provocan una gran pérdida de carga en el aire que circula a través de ellas. En consecuencia, su tamaño limita significativamente el caudal circulante y da lugar a lo que se conoce como quot;microventilaciónquot;, que no satisface la ventilación efectiva de las estancias. los usuarios se encuentran en numerosas ocasiones, sobre todo en temporada estival, con la necesidad simultánea de ventilar y oscurecer la estancia en las horas de sueño. Con los sistemas existentes de lamas, salvo el de lamas orienta bies, no se pueden satisfacer ambas necesidades al mismo tiempo. O bien se oscurece la estancia desplegando la persiana, o bien se ventila de forma efectiva recogiéndola en el capialzado. Por tanto, sería deseable poder satisfacer ambas necesidades simultáneamente mediante un sistema económico. Como concepto, cabe señalar que la ventilación en los edificios suministra la cantidad requerida de aire bajo unas condiciones climáticas y ambientales determinadas. El proceso impulsa aire limpio hacia el interior de las estancias a través de los cerramientos, favoreciendo en todo momento los procesos de ventilación de origen natural (en contraposición a los de origen mecánico). El movimiento del aire tiene su origen en un gradiente de presiones generado por procesos de convección natural o forzada. En los edificios residenciales, y en la mayoría de los públicos, este gradiente se traduce en una depresión en el interior de los espacios que provoca la entrada del aire exterior. Aparte de los beneficios que implica la entrada de aire fresco (menos contaminado) para la renovación y eliminación de posibles focos contaminantes, existe un beneficio añadido de regulación térmica en ciertas horas del verano, cuando la temperatura exterior es inferior a la existente en el interior de los espacios y, además, la presencia de corrientes controladas de aire (evitando altas velocidades que las conviertan en molestas) favorecen la evaporación humana y la prevención de zonas de estancamientos o quot;islas de calorquot; interiores. La cultura popular mediterránea ha interactuado con estos procesos físicos procediendo a abrir las ventanas por las noches y favoreciendo el oscurecimiento interior en las horas centrales del día. Sin embargo, la sociedad actual ha tendido al oscurecimiento total mediante persianas en las horas nocturnas, lo que dificulta enormemente el movimiento del aire y el enfriamiento natural. Bien es cierto que las actuales persianas disponen de pequeñas aberturas de ventilación entre las lamas que las componen, pero los estudios demuestran que la pérdida de carga que supone el tránsito del aire a través de ellas dificulta su paso y, dado el pequeño valor del gradiente de presiones interior/exterior, el aire no circula o bien tiende a penetrar por otras aberturas abiertas directamente al exterior (localizados en otras estancias de la vivienda). Esto se traduce en que en los dormitorios la temperatura interior no baja acorde al enfriamiento nocturno exterior, provocando una sensación de ausencia de confort o el uso de medios alternativos de control ambiental (de origen mecánico). El objeto de la presente invención es, por todo lo expuesto anteriormente, crear unas lamas que permitan satisfacer simultáneamente las necesidades de ventilación y de oscurecimiento con una repercusión económica reducida, y para las que se puedan utilizar el resto de elementos usuales de las persianas. At present, different systems of roller blinds are known formed by a set of horizontal slats separated by lower and narrow guides, made in the upper part of them, which are housed in a lower notch, and which allow them to be articulated and rolled up all the cloth inside the capialzado. These slats, usually plastic or metallic, are flat and opaque in most cases, running through vertical guides
usually located on the sides. In some systems, the main slats are independent and orientated, lacking the connection system described above. Its market price is much higher than the conventional one and also require a mechanical drive with power supply. the smaller and narrower slats, which link and articulate the main ones, are not opaque and are normally perforated with small grooves that, in theory, would allow the passage of air and light. However, its small dimensions, not usually reach the square centimeter, cause a great loss of load in the air that circulates through them. Consequently, its size significantly limits the flow rate and gives rise to what is known as "microventilation", which does not satisfy the effective ventilation of the rooms. Users find themselves on numerous occasions, especially in the summer season, with the simultaneous need to ventilate and obscure the stay during sleeping hours. With existing slat systems, except for the slat orientated slats, both needs cannot be met at the same time. Either the room is darkened by unfolding the blind, or it is effectively ventilated by picking it up in the capital. Therefore, it would be desirable to be able to satisfy both needs simultaneously through an economic system. As a concept, it should be noted that ventilation in buildings supplies the required amount of air under certain climatic and environmental conditions. The process drives clean air into the rooms through the enclosures, favoring ventilation processes of natural origin at all times (as opposed to those of mechanical origin). Air movement has its origin in a pressure gradient generated by natural or forced convection processes. In residential buildings, and in most public buildings, this gradient translates into a depression inside the spaces that causes outside air to enter. Apart from the benefits implied by the entry of fresh (less polluted) air for the renewal and elimination of possible polluting sources, there is an added benefit of thermal regulation at certain times of the summer, when the outside temperature is lower than the one inside of the spaces and, in addition, the presence of controlled air currents (avoiding high speeds that make them annoying) favor human evaporation and the prevention of areas of stagnation or "islands of heat"; interiors The popular Mediterranean culture has interacted with these physical processes by opening the windows at night and favoring the interior darkening in the central hours of the day. However, today's society has tended to total blackout through nighttime blinds, which greatly hinders air movement and natural cooling. It is true that the current blinds have small ventilation openings between the slats that compose them, but studies show that the loss of load caused by the transit of air through them hinders their passage and, given the small value of the gradient With internal / external pressures, the air does not circulate or tends to penetrate through other open openings directly to the outside (located in other rooms of the house). This translates into the fact that in the bedrooms the indoor temperature does not fall according to the outdoor night cooling, causing a feeling of absence of comfort or the use of alternative means of environmental control (of mechanical origin). The object of the present invention is, for all the foregoing, to create slats that simultaneously satisfy the needs of ventilation and darkening with a reduced economic impact, and for which the rest of the usual elements of the blinds can be used.

Figura 4: Secciones transversales de la lama por el hueco y el dispositivo móvil de apertura y cierre con los mismos elementos antes descritos. Descripción detallada de la realización preferente de la invención A continuación se describe una forma preferida de realizar la invención, no limitativa en cuanto su alcance. De acuerdo con la figura 1, las perforaciones se practican en las lamas enrollables 1 que actualmente se encuentran en el mercado. Estas lamas son horizontales y consisten en perfiles huecos, rellenos o no con aislamiento termoacústico, fabricados habitualmente con aluminio o PVC, y con unas dimensiones comerciales de 39.5, 44.0, 50.0 Y 55.0 mm de altura. Estas lamas se articulan por medio de unas guías en forma de gancho 2 que las prolongan por su canto superior, más estrechas y de menor altura, que se engarzan en una ranura 3 practicada en el canto inferior de la misma lama. Este sistema permite la articulación de las lamas para poder enrollarlas en el interior del capialzado. Por lo tanto, la presente invención no altera el funcionamiento convencional de las persianas actuales. Para su ejecución se conforma en principio un marco 5 para delimitar perimetralmente las perforaciones 4 que se practican en las lamas 1. La sección del marco 5 tendrá forma de l/Uquot; en uno de los laterales y en su parte superior e inferior. En estos últimos se encajará el dispositivo móvil 6 y marcarán la dirección del movimiento del mismo. En el lateral restante se deja una abertura con la altura del dispositivo móvil para permitir su desplazamiento lateral al interior Brief description of the drawings To complement the description of this invention and in order to facilitate the understanding of its characteristics, a series of figures are attached in which, for illustrative and non-limiting purposes, the following has been represented: Figure 1: Perspective from a blind with perforated slats, where (1) represents the slat, (2) the hook, (3) groove, (4) perforations, (5) frame, (6) sliding device, (7) pull. Figure 2: Perspective in detail of one of the perforations, with the same elements described above. Figure 3: Perspective of a form of execution of the practicable or sliding opening with the same elements described above. Figure 4: Cross sections of the slat through the hole and the mobile opening and closing device with the same elements described above. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION The following describes a preferred way of carrying out the invention, not limiting in scope. According to figure 1, the perforations are practiced in the rolling slats 1 that are currently on the market. These slats are horizontal and consist of hollow profiles, filled or not with thermoacoustic insulation, usually made of aluminum or PVC, and with commercial dimensions of 39.5, 44.0, 50.0 and 55.0 mm high. These slats are articulated by means of hook-shaped guides 2 that extend them by their upper edge, narrower and of lower height, which are engaged in a groove 3 practiced in the lower edge of the same slat. This system allows the articulation of the slats to be able to wind them inside the capialzado. Therefore, the present invention does not alter the conventional operation of current blinds. In order to execute it, a frame 5 is formed in principle to delimit the perforations 4 that are practiced in the slats 1. The section of the frame 5 will have the shape of a Uquot; on one of the sides and on its top and bottom. In the latter the mobile device 6 will be fitted and will mark the direction of movement thereof. On the remaining side, an opening is left with the height of the mobile device to allow its lateral movement inside
de la sección de la lama 1. El dispositivo móvil irá encajado en el interior del marco 5 entre las of the section of the plank 1. The mobile device will fit inside the frame 5 between the
guías superior e inferior, en su posición de cerrado. Las dimensiones del marco 5 dependerán de la altura comercial de la lama 1. Tendrán una altura 15 mm más pequeña que la de la lama 1, mientras que su longitud será de 5 veces la upper and lower guides, in their closed position. The dimensions of the frame 5 will depend on the commercial height of the blade 1. They will have a height 15 mm smaller than that of the blade 1, while its length will be 5 times the
5 altura. Se ha comprobado, experimental y numéricamente, que esta proporción opone escasa resistencia al paso del aire, permitiendo la ventilación incluso con pequeños gradientes de presión entre el interior y el exterior. En los casos más desfavorables se consiguen secciones libres de alrededor de 40 cm 2, hueco que posibilita el paso de un caudal de 10 l/s a una velocidad de 2,5 mis. La longitud de las perforaciones podrá estar entre 10 y 30 cm y la altura entre 5 height It has been proven, experimentally and numerically, that this proportion opposes low resistance to the passage of air, allowing ventilation even with small pressure gradients between inside and outside. In the most unfavorable cases, free sections of about 40 cm 2 are achieved, a gap that allows the flow of 10 l / s at a speed of 2.5 m. The length of the perforations may be between 10 and 30 cm and the height between
10 3 Y 12 cm. El marco 5 se fabrica con PVC, mientras que el dispositivo móvil 6 puede ser de PVC o aluminio. En uno de los extremos del dispositivo móvil se practica una pequeña entalladura a modo de tirador 7 para facilitar su manipulación. En la lama 1 se realiza una perforación rectangular con la misma proporción que los marcos 10 3 and 12 cm. The frame 5 is manufactured with PVC, while the mobile device 6 can be made of PVC or aluminum. At one end of the mobile device a small notch is practiced as a handle 7 to facilitate its handling. In lama 1 a rectangular perforation with the same proportion as the frames is made
