BREVE DESCRIPCIÓN DE LA INVENCIÓNBRIEF DESCRIPTION OF THE INVENTION
La presente invención es una mejora en el sector de las cortinas y estores.The present invention is an improvement in the sector of curtains and blinds.
En esta patente el inventor da un paso más en Ia idea de ofrecer un producto de máxima calidad, sin errores o fallos en el funcionamiento y con una fácil mecánica para su montaje.In this patent the inventor goes a step further in the idea of offering a product of the highest quality, without errors or failures in operation and with an easy mechanics for its assembly.
Así, ha desarrollado un mecanismo que comprende unas guías laterales y que al enrollarse impide que se creen abultamientos en el interior del cajetín. Hasta ahora al enrollarse una cortina, ésta se malformaba y se arrugaba, especialmente si pasaba algún tiempo en Ia
posición de enrollada. El problema venía al desenrollarla porque dichas malformaciones o arrugas no desaparecían y visualmente no quedaba perfecta Ia cortina.Thus, it has developed a mechanism that includes some lateral guides and that when rolled up prevents bulging inside the box. Until now, when a curtain was rolled, it was malformed and wrinkled, especially if I spent some time in Ia coiled position The problem came when unrolling it because these malformations or wrinkles did not disappear and visually the curtain was not perfect.
Habitualmente, los mecanismos que incorporan guías laterales disponen de un elemento guiador. Dicho elemento guiador es un problema cuando se enrolla Ia cortina o estor, tal y como se ha indicado en el párrafo anterior. Las soluciones pasan por dos modos de enrollado.Usually, the mechanisms incorporating lateral guides have a guiding element. Said guiding element is a problem when the curtain or blind is wound, as indicated in the previous paragraph. The solutions go through two winding modes.
Un primero en el que unas pletinas laterales se disponen al enrollarse unas encima de otras, Io que supone un trabajo de matemática para hacer coincidir entre sí dichas pletinas. Otro problema es que el cajetín debe ser muy grande debido a que las pletinas al superponerse y ser más gruesas que Ia propia cortina o estor, aumentan el espacio necesario en el interior del cajetín.A first one in which some lateral plates are arranged when being rolled up on top of each other, which is a work of mathematics to make said plates coincide with each other. Another problem is that the box must be very large because the plates when overlapping and being thicker than the curtain itself or blinds, increase the necessary space inside the box.
La segunda opción es eliminar las pletinas y no hacerlas coincidir, pero ello ocasiona que al contactar una pletina, de Ia capa enrollada superior con Ia tela de Ia capa enrollada inferior, Ia marca y arruga, afeándola a Ia vista cuando se desenrolla.The second option is to eliminate the plates and not make them coincide, but this causes that when contacting a plate, of the upper rolled layer with the fabric of the lower rolled layer, the mark and wrinkle, affecting the eye when it is unwound.
Así, el inventor ha tratado de solventar, con una misma invención, los dos problemas antes citados. La presente invención combina los dos efectos positivos de las soluciones anteriores, es decir, no arruga ni malforma el estor o Ia cortina, y por otro lado no precisa de aumentar el volumen del cajetín.Thus, the inventor has tried to solve, with the same invention, the two problems mentioned above. The present invention combines the two positive effects of the above solutions, that is, it does not wrinkle or malform the blind or the curtain, and on the other hand it does not need to increase the volume of the box.
Ello se consigue mediante el empleo de unos remaches o elementos seguidores, dispuestos de manera predeterminada longitudinalmente a Io largo del perímetro lateral, recortando Ia cortina o estor existente entre un remache o elemento seguidor y el siguiente, definiendo unas concavidades.This is achieved through the use of rivets or follower elements, arranged in a predetermined manner longitudinally along the lateral perimeter, by cutting the curtain or blind existing between a rivet or follower element and the next, defining concavities.
De este modo, al enrollarse, los remaches o elementos seguidores no coinciden, por Io que no se abulta, y por otro lado dichos remaches o elementos seguidores no arrugan ninguna parte de Ia cortina o estor, ya que al enrollarse siempre coinciden con una parte recortada, por Io que no afectan a Ia cortina o estor.
Es un objeto de Ia presente invención un mecanismo de guiado para cortinas y estores, del tipo que comprende un cajetín longitudinal, unas guías laterales, una cortina o estor dispuesta parcialmente en el interior de las guías laterales con unos estrechamientos, un tambor giratorio con sus medios de accionamiento, y una barra inferior unida al perímetro inferior de Ia cortina o estor, caracterizado porque comprende: unas lengüetas o extensiones de Ia cortina o estor, dispuestos a Io largo del perímetro lateral de Ia cortina o estor, definiendo unos espacios o concavidades entre una lengüeta o extensión y Ia inmediatamente siguiente, y unos remaches o elementos seguidores dispuestos en las lengüetas o extensiones, que se sitúan dichos remaches o elementos seguidores en el interior de las guías laterales sobre las que discurren, con un grosor superior al estrechamiento de las guías laterales.Thus, when winding, the rivets or follower elements do not coincide, so it does not bulge, and on the other hand said rivets or follower elements do not wrinkle any part of the curtain or blind, since when they are rolled they always coincide with a part cropped, so they do not affect the curtain or blind. It is an object of the present invention a guiding mechanism for curtains and blinds, of the type comprising a longitudinal box, lateral guides, a curtain or blind arranged partially inside the lateral guides with narrowings, a rotating drum with its actuation means, and a lower bar attached to the lower perimeter of the curtain or blind, characterized in that it comprises: tabs or extensions of the curtain or blind, arranged along the lateral perimeter of the curtain or blind, defining spaces or concavities between a tongue or extension and the immediately following, and some rivets or follower elements arranged in the tabs or extensions, which said rivets or follower elements are located inside the lateral guides on which they run, with a thickness greater than the narrowing of the side guides.

CONCRETA REALIZACIÓN DE LA PRESENTE INVENCIÓN
Así en Ia figura 1 se ilustra un cajetín longitudinal 1 , una cortina o estor 2 que define su perímetro lateral 8 y su perímetro inferior 7, unas guías laterales 4, y una barra inferior 5.CONCRETE REALIZATION OF THIS INVENTION Thus, in Figure 1 a longitudinal box 1, a curtain or blind 2 that defines its lateral perimeter 8 and its lower perimeter 7, lateral guides 4, and a lower bar 5 is illustrated.
En Ia figura 2 se ha representado Ia cortina o estor 2, Ia guía lateral 4 formada por un perfil 21 , un remache o elemento seguidor 6, una lengüeta o extensión 9, un embudo 14, un estrechamiento 12 y un felpudo 13.Figure 2 shows the curtain or blind 2, the lateral guide 4 formed by a profile 21, a rivet or follower element 6, a tongue or extension 9, a funnel 14, a narrowing 12 and a mat 13.
La figura 3 muestra el cajetín longitudinal 1 , Ia cortina o estor 2 con su perímetro lateral 8, un tambor giratorio 3 con sus medios de accionamiento 18, las lengüetas o extensiones 9 con su espacio o concavidad 10, los remaches o elementos seguidores 6 y un adaptadorFigure 3 shows the longitudinal box 1, the curtain or blind 2 with its lateral perimeter 8, a rotating drum 3 with its actuating means 18, the tabs or extensions 9 with its space or concavity 10, the rivets or follower elements 6 and an adapter
15.fifteen.
En Ia figura 4 se ha dibujado el adaptador 15 con las primeras rampas 16 y las segundas rampas 17. De este modo, en una concreta realización, en este caso se tratará de una cortina 2 con remaches 6 localizados en unas lengüetas 9 que forman unas concavidades 10.In Figure 4 the adapter 15 has been drawn with the first ramps 16 and the second ramps 17. Thus, in a specific embodiment, in this case it will be a curtain 2 with rivets 6 located on tabs 9 that form concavities 10.
Así el presente mecanismo, en posición inicial es tal y como se muestra en Ia Fig.1 , es decir con un cajetín longitudinal 1 , una cortina o estor 2 que define su perímetro lateral 8 y su perímetro inferior 7, unas guías laterales 4, y una barra inferior 5.Thus, the present mechanism, in the initial position, is as shown in Fig. 1, that is to say with a longitudinal box 1, a curtain or blind 2 defining its lateral perimeter 8 and its lower perimeter 7, lateral guides 4, and a bottom bar 5.
Cuando el usuario decide subir o enrollar Ia cortina 2, (Fig. 3) Io realizará de Ia siguiente manera. Pondrá en marcha los medios de accionamiento 18 del tambor (bien de manera manual o eléctrica) y éstos hacen girar el tambor giratorio 3 que va enrollando Ia cortina 2.When the user decides to raise or roll the curtain 2, (Fig. 3) I will do it as follows. It will start the drum drive means 18 (either manually or electrically) and they rotate the rotating drum 3 that winds the curtain 2.
La cortina dispone de unas lengüetas 9 dispuestas a Io largo del perímetro lateral 8 de Ia cortina 2. Dichas lengüetas definen unos espacios o concavidades 10 entre una lengüeta 9 y Ia inmediatamente siguiente. En cada una de dichas lengüetas 9 se dispone un remache 6.The curtain has tabs 9 arranged along the lateral perimeter 8 of the curtain 2. Said tabs define spaces or concavities 10 between a tongue 9 and the immediately following. A rivet 6 is provided on each of said tongues 9.
Estos remaches 6 quedan situados en el interior de las guías laterales 4 (Fig. 2) sobre las que discurren. Para evitar que puedan salir del interior
de las guías laterales 4, los remaches 6 disponen de un grosor superior al espacio que define el estrechamiento 12 de las guías laterales 4, de tal manera que no pueden salir los remaches 6 por el estrechamiento 12.These rivets 6 are located inside the lateral guides 4 (Fig. 2) on which they run. To prevent them from leaving inside of the lateral guides 4, the rivets 6 have a thickness greater than the space that defines the narrowing 12 of the lateral guides 4, such that the rivets 6 cannot exit through the narrowing 12.
Tal y como se muestra en Ia Fig. 3 al irse enrollando Ia cortina 2 en el tambor giratorio 3 dicha cortina 2 queda dispuesta en capas, de tal modo que las concavidades 10 de Ia capa superior coinciden con las lengüetas 9 y remaches 6 de Ia capa inferior.As shown in Fig. 3 as the curtain 2 is wound in the rotating drum 3, said curtain 2 is arranged in layers, such that the concavities 10 of the upper layer coincide with the tabs 9 and rivets 6 of the lower layer.
Así, de este modo, se evita que Ia cortina tenga malformaciones en el tejido de Ia misma y no hayan bultos y se formen arrugas, tal y como se ha detallado con mayor profusión en Ia BREVE DESCRIPCIÓN DE LA PRESENTE INVENCIÓN.Thus, in this way, the curtain is prevented from having malformations in the tissue thereof and there are no lumps and wrinkles are formed, as detailed in greater detail in the BRIEF DESCRIPTION OF THE PRESENT INVENTION.
Adicionalmente, tal y como se muestra en Ia Fig. 2 se puede disponer que las guías laterales 4 estén formadas por un perfil 21 , ya que dicho perfil favorece y permite una fabricación más sencilla de las guías laterales.Additionally, as shown in Fig. 2, it can be provided that the lateral guides 4 are formed by a profile 21, since said profile favors and allows a simpler manufacture of the lateral guides.
En dicho perfil 21 se podrán disponer en su interior unos felpudos 13, encarados a Ia cortina 2. Ello tiene dos ventajas:In said profile 21, some mats 13 can be arranged inside, facing the curtain 2. This has two advantages:
Una primera ventaja que consiste en que se aisla lumínicamente Ia parte que queda oculta de Ia cortina 2, ya que dichos felpudos 13 forman parte de unas medidas que impiden el paso de Ia luz hacia el interior del perfil 21. Así, para aislar lumínicamente, se dimensiona Ia cortina 2 de manera adecuada para que quede situada por su perímetro lateral 8 en el interior de las guías laterales 4. Además los remaches 6 impiden que se escape Ia cortina 2 del interior del perfil 21. Y por último, Ia incorporación de piezas de cierre como el felpudo 13 y el embudo 14 aislan completamente de Ia luz dicho perímetro lateral 8 de Ia cortina.A first advantage is that the hidden part of the curtain 2 is lightly isolated, since said mats 13 are part of measures that prevent the passage of light into the profile 21. Thus, to insulate lightly, the curtain 2 is sized appropriately so that it is located by its lateral perimeter 8 inside the lateral guides 4. In addition, the rivets 6 prevent the curtain 2 from escaping inside the profile 21. And finally, the incorporation of Closing pieces such as the door mat 13 and the funnel 14 completely isolate said lateral perimeter 8 from the curtain from the light.
Y una segunda ventaja que consiste en que se evita que se introduzca polvo dentro del perfil 21 hacia los remaches 6 y por ende al tambor giratorio 3. Una de las maneras de configurar el estrechamiento 12, para evitar que no se escapen los remaches 6 del interior de Ia guía lateral 4, consiste en que el perfil 21 comprenda una configuración en forma de
embudo 14 al final del cual se localiza el mencionado estrechamiento 12, de este modo adoptando dicha configuración en embudo 14 se asegura que aun cuando hubieran tirones en Ia cortina 2, los remaches 6 no puedan salir nunca del interior del perfil 21. Para conectar el cajetín longitudinal 1 y las guías laterales 4 se ha previsto Ia disposición de un adaptador 15 (Fig. 4), que comprende en su interior unas primeras rampas 16, enfrentadas entre sí, que guían Ia cortina 2 sobre los felpudos 13 y unas segundas rampas 17 que guían los remaches 6 hacia el estrechamiento 12 del embudo 14, tanto en las operaciones de enrollamiento o subida de Ia cortina 2 como de desenrollamiento o bajada de Ia cortina 2.And a second advantage is that it prevents dust from entering the profile 21 towards the rivets 6 and therefore the rotating drum 3. One of the ways to configure the narrowing 12, to prevent the rivets 6 from escaping from the inside the lateral guide 4, is that the profile 21 comprises a configuration in the form of funnel 14 at the end of which the aforementioned narrowing 12 is located, thus adopting said funnel configuration 14 ensures that even if there were pulls on the curtain 2, the rivets 6 can never leave the inside of the profile 21. To connect the longitudinal box 1 and the lateral guides 4 the arrangement of an adapter 15 (Fig. 4) is provided, which comprises first ramps 16, facing each other, that guide the curtain 2 on the mats 13 and second ramps 17 that guide the rivets 6 towards the narrowing 12 of the funnel 14, both in the winding or raising operations of the curtain 2 and of unrolling or lowering the curtain 2.
Este adaptador por un lado facilita que los remaches 6 queden debidamente dispuestos en el tambor giratorio 3, tal y como se ha explicado anteriormente, y que posteriormente cuando se baja Ia cortina 2, que dichos remaches queden alojados más allá del embudo 14, de tal manera que no puedan salir del interior del perfil 21.This adapter on the one hand facilitates that the rivets 6 are properly arranged in the rotating drum 3, as explained above, and that later when the curtain 2 is lowered, that said rivets are housed beyond the funnel 14, of such so that they cannot leave inside the profile 21.
Para facilitar el guiado de los remaches hacia el interior del perfil 21 las segundas rampas 17 están inclinadas con respecto a las primeras rampas 16, siendo dicha inclinación una prolongación del embudo 14. La presente patente de invención describe un nuevo mecanismo de guiado para cortinas y estores. Los ejemplos aquí mencionados no son limitativos de Ia presente invención, por ello podrá tener distintas aplicaciones y/o adaptaciones, todas ellas dentro del alcance de las siguientes reivindicaciones.
