DESCRIPCIONDESCRIPTION

Una puerta flexibleA flexible door

La presente invencion se refiere a una puerta flexible, en particular, pero no exclusivamente, una puerta flexible que esta destinada a aislar zonas de acceso frecuente dentro de un edificio, tales como almacenes en frio, zonas de almacenamiento, etc., de otras zonas dentro o fuera del edificio.The present invention relates to a flexible door, in particular, but not exclusively, a flexible door that is intended to isolate areas of frequent access within a building, such as cold stores, storage areas, etc., from other areas. inside or outside the building.

El documento US 3 295 589 A describe una puerta flexible con todas las caracteristicas del preambulo de la reivindicacion 1.Document US 3 295 589 A describes a flexible door with all the features of the preamble of claim 1.

En muchos edificios es deseable poder aislar ciertas zonas del edificio de otras zonas. Los ejemplos de situaciones en donde es deseable tal aislamiento incluyen el aislamiento de zonas para separarlas del acceso publico o para impedir el flujo de aire de una zona a otra. Un ejemplo especifico de situacion en donde puede requerirse el aislamiento frente al flujo de aire lo constituye un supermercado o un almacen de distribucion en donde la zona de almacenamiento en frio debe estar cerrada con respecto a otras zonas del edificio a fin de mantener la temperatura y las condiciones atmosfericas del almacen frio dentro de ciertos parametros. Otros ejemplos en donde esto puede resultar beneficioso incluyen, pero sin limitacion, divisiones internas, zonas de temperatura controlada, zonas de lavado, zonas refrigeradas, zonas de elaboracion y preparation de alimentos, cocinas de restauracion y comerciales, supermercados y puntos de venta al por menor, hospitales y espacios sanitarios, etc.In many buildings it is desirable to be able to isolate certain areas of the building from other areas. Examples of situations where such isolation is desirable include isolation of zones to separate them from public access or to prevent air flow from one area to another. A specific example of a situation where insulation against air flow may be required is a supermarket or distribution warehouse where the cold storage area must be closed with respect to other areas of the building in order to maintain the temperature and the atmospheric conditions of the cold storage within certain parameters. Other examples where this may be beneficial include, but is not limited to, internal divisions, temperature controlled zones, washing zones, refrigerated areas, food processing and preparation areas, catering and commercial kitchens, supermarkets and retail outlets minor, hospitals and sanitary spaces, etc.

Tales divisiones se pueden lograr por medio de puertas rigidas estandar; sin embargo, dado que normalmente pasa por la puerta un alto volumen de trafico (y cargas voluminosas tales como personal con carros, etc.), en lugar de puertas rigidas, frecuentemente se realiza la separation colgando cortinas de plastico o material similar de un marco auxiliar de la puerta. Esto procura una barrera frente al flujo de aire entre un lado y otro de la puerta y tambien ayuda a proporcionar una separacion visual entre zonas publicas y privadas. Sin embargo, un problema de tales cortinas de plastico es que a menudo el usuario tiene que agacharse por debajo de las cortinas cuando pasa a traves de la puerta, lo que tiende a dificultar el paso a traves de las mismas. Ademas, cuando tales puertas comprenden marcos auxiliares rigidos y cortinas de plastico flexible, se requiere una cierta cantidad de espacio libre a ambos lados de la puerta para permitir que la puerta se abra y cierre sin impedimento.Such divisions can be achieved through standard rigid doors; however, since a high volume of traffic (and bulky loads such as personnel with cars, etc.) normally passes through the door, instead of rigid doors, separation is often performed by hanging plastic curtains or similar material from a frame auxiliary door. This provides a barrier against the flow of air between one side and the other of the door and also helps to provide a visual separation between public and private areas. However, a problem with such plastic curtains is that the user often has to duck under the curtains when passing through the door, which tends to hinder the passage through them. In addition, when such doors comprise rigid auxiliary frames and flexible plastic curtains, a certain amount of free space is required on both sides of the door to allow the door to open and close without hindrance.

Segun un primer aspecto de la presente invencion, se proporciona una puerta flexible que comprende una estructura principal de puerta, una disposition de fijacion para asegurar la estructura principal de puerta a un marco de puerta y una disposicion de bisagra adaptada para permitir el movimiento batiente articulado de la estructura principal de puerta sobre el marco de puerta, entre una configuration cerrada y una configuration al menos parcialmente abierta, y en donde la estructura principal de puerta comprende al menos un miembro elastico de soporte adaptado para permitir que la puerta se flexione con un radio de curvatura cuando se aplica sobre la puerta una fuerza de apertura, en donde la elasticidad proporcionada por el miembro elastico de soporte esta configurada de manera que, cuando se aplica sobre la puerta una fuerza de apertura que no llega a una fuerza de apertura umbral, el miembro elastico de soporte y por lo tanto la estructura principal de puerta se flexionaran bajo la action de dicha fuerza sustancialmente sin que se produzca ningun movimiento batiente articulado en la disposicion de bisagra y, cuando se aplica sobre la puerta una fuerza de apertura por encima de dicha fuerza de apertura umbral, ademas de que el miembro elastico de soporte y por lo tanto la estructura principal de puerta se flexionen bajo la accion de tal fuerza, se produzca movimiento batiente articulado de la puerta sobre la disposicion de bisagra.According to a first aspect of the present invention, a flexible door is provided comprising a main door structure, a fixing arrangement for securing the main door structure to a door frame and a hinge arrangement adapted to allow hinged swinging movement. of the main door structure on the door frame, between a closed configuration and an at least partially open configuration, and wherein the main door structure comprises at least one elastic support member adapted to allow the door to flex with a radius of curvature when an opening force is applied to the door, where the elasticity provided by the elastic support member is configured such that, when an opening force is applied to the door that does not reach a threshold opening force , the elastic support member and therefore the main door structure will flex under the action of said force substantially without any hinged movement articulated in the hinge arrangement and, when an opening force is applied over the door above said threshold opening force, in addition to the elastic support member and therefore both the main door structure flexes under the action of such force, articulated swinging movement of the door on the hinge arrangement occurs.

Otras caracteristicas y ventajas de la presente invencion resultaran evidentes a partir de las reivindicaciones y la description siguiente.Other features and advantages of the present invention will be apparent from the claims and the following description.

las Figuras 12 y 13 son diagramas esquematicos que ilustran realizaciones alternativas de la puerta flexible con distintos grados de rigidez a la flexion y por lo tanto distintos grados maximos de radios de curvatura.Figures 12 and 13 are schematic diagrams illustrating alternative embodiments of the flexible door with different degrees of flexural rigidity and therefore different maximum degrees of radii of curvature.

Haciendo referencia particular a las Figuras 1 y 2, un panel de puerta 10 de una estructura principal de puerta comprende un miembro elastico de soporte que, en la presente realization, comprende un brazo 12 de soporte, de policarbonato, y una hoja 14 de puerta, flexible y dotada de aislamiento, suspendida del mismo. Tambien se provee a lo largo del borde superior de la puerta 10 un cierre superior 16 frente al aire, flexible. El borde interno de la hoja 14 de puerta esta provisto de una disposicion de fijacion en forma de un perfil 18 de anclaje longitudinal que se corresponde con un perfil 20 de montaje longitudinal dispuesto sobre una bisagra 22 de dos sentidos, a fin de permitir que se fije el panel de la puerta 10 a un marco de puerta y pueda batir articuladamente en cualquier sentido. Como se muestra en la Figura 1, la bisagra 22 comprende tambien un protector flexible 24 de bisagra que tiene un par de solapas flexibles que cubren el intersticio entre la base del panel de puerta 10 y la bisagra 22, para evitar atrapamiento de dedos, etc. entre las mismas. Entre el perfil 18 de anclaje y el material de cada hoja 14 de puerta estan dispuestas tiras 21, 23 de cubierta intermedia. Los bordes longitudinales de las tiras 21, 23 de cubierta estan acoplados a la hoja 14 de puerta mediante medios de acoplamiento desprendibles que, en la presente realizacion, comprenden tiras verticales 26, 28 de material de tipo gancho y bucle (mejor ilustrado en la Figura 10). Cada hoja 14 de puerta tiene tambien una ventana visual 15 de plastico, dispuesta a su traves; esta puede comprender paneles transparentes rlgidos o flexibles.With particular reference to Figures 1 and 2, a door panel 10 of a main door structure comprises an elastic support member which, in the present embodiment, comprises a support arm 12, made of polycarbonate, and a door leaf 14 , flexible and insulated, suspended from it. A flexible upper closure 16 is also provided along the upper edge of the door 10 in front of the air. The inner edge of the door leaf 14 is provided with a fixing arrangement in the form of a longitudinal anchoring profile 18 corresponding to a longitudinal mounting profile 20 arranged on a two-way hinge 22, in order to allow it fix the door panel 10 to a door frame and you can beat articulately in any direction. As shown in Figure 1, the hinge 22 also comprises a flexible hinge guard 24 having a pair of flexible flaps covering the gap between the base of the door panel 10 and the hinge 22, to avoid finger entrapment, etc. . between them. Between the anchoring profile 18 and the material of each door leaf 14, intermediate cover strips 21, 23 are arranged. The longitudinal edges of the cover strips 21, 23 are coupled to the door leaf 14 by removable coupling means which, in the present embodiment, comprise vertical strips 26, 28 of hook and loop type material (better illustrated in Figure 10). Each door leaf 14 also has a visual window 15 of plastic, arranged therethrough; This may include rigid or flexible transparent panels.

Como se muestra en la Figura 3, tlpicamente se disponen uno junto a otro un par de paneles flexibles de puerta 10; sin embargo, como alternativa se podrla disponer un unico panel flexible de puerta 10 de forma aislada, o bien se podrlan disponer varios paneles de puerta flexibles 10 uno junto al otro o en serie (uno tras otro), dependiendo de la funcionalidad requerida. Hacia el borde externo de cada hoja 14 de puerta se dispone un borde 29 de cierre vertical con el fin de procurar un cierre frente al aire entre las dos hojas 14 de puerta de cada panel de puerta adyacente. Ademas, hacia la parte inferior de cada hoja 14 de puerta tambien se dispone una solapa 31 de cierre inferior de la puerta, para ayudar a procurar un cierre frente al aire entre el borde inferior de la hoja 14 de puerta y la superficie delAs shown in Figure 3, typically a pair of flexible door panels 10 are arranged next to each other; however, as an alternative a single flexible door panel 10 could be arranged in isolation, or several flexible door panels 10 could be arranged next to each other or in series (one after another), depending on the functionality required. Towards the outer edge of each door leaf 14 a vertical closing edge 29 is arranged in order to ensure an air-facing closure between the two door leaves 14 of each adjacent door panel. Also, towards the bottom of each door leaf 14, a lower door closure flap 31 is also provided, to help ensure an air-tight closure between the lower edge of the door leaf 14 and the surface of the door.

suelo situada debajo. Un marco 11 de puerta y la pared 13 circundan al par de puertas flexibles 10.ground below. A door frame 11 and the wall 13 surround the pair of flexible doors 10.

Durante el uso, cuando un usuario empuje un panel de puerta 10 (con la mano, mediante un carro o de cualquier otra manera) con una fuerza de apertura que no llega a un umbral predeterminado de fuerza de apertura, el brazo elastico 12 de soporte y por tanto la hoja 14 de puerta se flexionaran desde su configuracion neutra ilustrada en la Figura 6 a una configuracion curvada/flexionada ilustrada en la Figura 7, sin ningun movimiento de la bisagra 22.During use, when a user pushes a door panel 10 (by hand, by means of a car or in any other way) with an opening force that does not reach a predetermined threshold of opening force, the elastic support arm 12 and therefore the door leaf 14 will flex from its neutral configuration illustrated in Figure 6 to a curved / flexed configuration illustrated in Figure 7, without any movement of the hinge 22.

Si se continua empujando el panel de puerta 10 con una fuerza que es mayor que el umbral predeterminado de fuerza de apertura, en lugar de flexionar adicionalmente el panel de puerta 10 y la hoja 14 de puerta asociada, la fuerza de empuje continuada provoca que la bisagra 22 se abra como se ilustra en la Figura 8. Como se ilustra en la Figura 9, esto es particularmente util cuando la puerta 10 esta dispuesta en un pasillo estrecho 30 que tiene una pared proxima 32, ya que esto maximiza la accesibilidad para el usuario (y para carros, etc.) a este espacio confinado, no solo por permitir la apertura batiente articulada de la puerta, sino tambien por garantizar que la puerta abierta se repliega hacia la pared 13. En este ejemplo, las paredes del almacen frlo 13 estan provistas de una puerta corredera adicional 33, que permite que la abertura detras de las puertas 10 quede cerrada con mayor seguridad, por ejemplo por la noche o durante otros perlodos de poco trafico a traves de las puertas 10.If the door panel 10 is continued to be pushed with a force that is greater than the predetermined threshold of opening force, instead of additionally flexing the door panel 10 and the associated door leaf 14, the continuous pushing force causes the hinge 22 opens as illustrated in Figure 8. As illustrated in Figure 9, this is particularly useful when the door 10 is arranged in a narrow aisle 30 that has a proximal wall 32, as this maximizes accessibility for the user (and for cars, etc.) to this confined space, not only for allowing the hinged articulated opening of the door, but also for ensuring that the open door is retracted towards the wall 13. In this example, the walls of the cold storage 13 are provided with an additional sliding door 33, which allows the opening behind the doors 10 to be closed more securely, for example at night or during other periods of low traffic through the doors 10.

Como mejor se ilustra en la Figura 10, a medida que el panel 12 de puerta se flexiona, las tiras 28 de tipo gancho yAs best illustrated in Figure 10, as the door panel 12 flexes, the hook-type strips 28 and

bucle dispuestas en la tira 23 de cubierta intermedia en ambos lados del panel de puerta 10 se desenganchan para admitir el estiramiento relativo de la hoja de puerta 14 en una cara de la puerta y la compresion en la otra cara de la puerta.loop arranged in the intermediate cover strip 23 on both sides of the door panel 10 are disengaged to admit the relative stretching of the door leaf 14 on one side of the door and compression on the other side of the door.

La elasticidad del brazo 12 de soporte se puede modificar durante la fabrication para proporcionar una gama de puertas con distintos grados de flexibilidad. Esto determina la fuerza de apertura umbral predeterminada requerida para que comience a abrirse la bisagra, en lugar de que continue flexionandose el brazo 12 de soporte, y tambien determina el grado del radio de curvatura de la puerta para una fuerza de empuje dada. A este respecto, como se muestra en la Figura 11, un brazo 12 de soporte muy delgado puede flexionarse alejandose mucho de la position neutra (indicada por la llnea de trazos A) en cualquier sentido, por ejemplo con un radio de curvatura de 3.200 mm ilustrado como posicion B y un radio de curvatura de 100 mm ilustrado como posicion C. Por lo tanto, esto permiteThe elasticity of the support arm 12 can be modified during fabrication to provide a range of doors with varying degrees of flexibility. This determines the predetermined threshold opening force required for the hinge to begin to open, instead of continuing to flex the support arm 12, and also determines the degree of radius of curvature of the door for a given pushing force. In this regard, as shown in Figure 11, a very thin support arm 12 can be flexed away from the neutral position (indicated by the dashed line A) in any direction, for example with a radius of curvature of 3,200 mm illustrated as position B and a radius of curvature of 100 mm illustrated as position C. Therefore, this allows

que la puerta se flexione en aproximadamente 180 grados en cualquiera de los dos sentidos desde la posicion neutra A.the door flexes approximately 180 degrees in either direction from neutral position A.

En una realizacion alternativa como se muestra en la Figura 12, en donde se dispone un brazo 12 de soporte mas grueso y/o mas rlgido, el radio de curvatura puede estar restringido a, por ejemplo, 1.200 mm y, en otra realizacion, en donde se dispone un brazo 12 de soporte mas estrecho y/o menos rlgido, el radio de curvatura puede estar restringido a, por ejemplo, 300 mm.In an alternative embodiment as shown in Figure 12, where a thicker and / or stiffer support arm 12 is arranged, the radius of curvature may be restricted to, for example, 1,200 mm and, in another embodiment, in where a narrower and / or less rigid support arm 12 is provided, the radius of curvature may be restricted to, for example, 300 mm.

Por tanto, la puerta flexible descrita en lo que antecede tiene la ventaja de flexionarse con, o sin, movimiento batiente articulado cuando se desee. Una ventaja de esto es que permite al usuario pasar mas facilmente a traves de la puerta. Ademas, la capacidad de flexion, combinada con el movimiento batiente articulado de la puerta flexible da como resultado una puerta que requiere una cantidad minima de espacio libre cuando se acciona entre las configuraciones abierta y cerrada.Therefore, the flexible door described above has the advantage of flexing with, or without, articulated swing movement when desired. An advantage of this is that it allows the user to pass more easily through the door. In addition, the flexural capacity, combined with the articulated swinging movement of the flexible door results in a door that requires a minimum amount of free space when operated between the open and closed configurations.
