DESCRIPCIONDESCRIPTION
Dispositivo de accionamiento motorizado y de soporte para persianas enrollables.Motorized drive and support device for roller blinds.
La presente invencion hace referencia a un dispositivo de accionamiento motorizado y de soporte para persianas enrollables para puertas de garajes, tiendas y edificios industrials en general.The present invention refers to a motorized drive and support device for roller shutters for garage doors, shops and industrial buildings in general.
Las figuras 1 y 2 muestran respectivamente un dispositivo (100) segun la tecnica anterior utilizado para enrollar y desenrollar persianas enrollables, asf como una persiana enrollable (5) fijado al dispositivo (100). El dispositivo (100) comprende una barra (no giratoria) de soporte fija (101). Dos o mas cajas con muelle de retencion (102) con forma circular estan montadas sobre la barra de soporte (101), girando ociosamente. Cada caja con muelle de retencion (102) contiene un muelle de compensacion (103) que se consigue generalmente con correas de acero bobinadas en configuracion en espiral. Un primer extremo del muelle de compensacion (103) esta fijado a la barra de soporte (101). Un segundo extremo del muelle de compensacion (103) esta fijado a la carcasa de las cajas con muelle de retencion (102).Figures 1 and 2 respectively show a device (100) according to the prior art used to wind and unwind roller blinds, as well as a roller blind (5) fixed to the device (100). The device (100) comprises a fixed support (non-rotating) bar (101). Two or more boxes with a retention spring (102) with a circular shape are mounted on the support bar (101), rotating idle. Each box with retaining spring (102) contains a compensation spring (103) that is generally achieved with coil-wound steel belts in spiral configuration. A first end of the compensation spring (103) is fixed to the support bar (101). A second end of the compensation spring (103) is fixed to the housing of the boxes with retention spring (102).
Un motor de engranajes o motorreductor (104) esta instalado en la barra de soporte (101). El motor de engranajes (104) acciona en rotacion una polea (140) que gira alrededor de un eje que coincide con el eje longitudinal de la barra de soporte (101). La polea (140) tiene el mismo diametro que las cajas con muelle de retencion (102). La persiana enrollable (5) tiene un borde superior (5a) fijado tanto a la polea (140) como a la carcasa de las cajas de muelle de retencion (102). Por lo tanto, las cajas con muelle de retencion (102) giran alrededor de la barra de soporte (101) cuando se acciona el motor de engranajes (104) para enrollar o desenrollar la persiana enrollable (5).A gear motor or gearmotor (104) is installed in the support bar (101). The gear motor (104) rotates a pulley (140) that rotates about an axis that coincides with the longitudinal axis of the support bar (101). The pulley (140) has the same diameter as the boxes with retention spring (102). The roller blind (5) has an upper edge (5a) fixed to both the pulley (140) and the housing of the retention spring boxes (102). Therefore, the boxes with retaining spring (102) rotate around the support bar (101) when the gear motor (104) is driven to wind or unwind the roller blind (5).
Los muelles de compensacion (103) se descargan cuando la persiana (5) se levanta y se enrolla completamente alrededor de la barra de soporte (101), mientras que los muelles (103) se cargan con la carga maxima cuando la persiana (5) se desenrolla completamente, segun se muestra la figura 2.The compensation springs (103) are discharged when the blind (5) is lifted and completely wrapped around the support bar (101), while the springs (103) are loaded with the maximum load when the blind (5) It unwinds completely, as shown in Figure 2.
Durante el recorrido descendente de la persiana (5), los muelles de compensacion (103) se cargan progresivamente, aprovechando el peso la persiana (5), mientras que durante el desplazamiento ascendente de la persiana, los muelles de compensacion (103) se descargan, contribuyendo de forma significativa a la fuerza de elevacion de la persiana ejercida por el motor de engranajes (104).During the downward travel of the blind (5), the compensation springs (103) are progressively loaded, taking advantage of the weight of the blind (5), while during the upward movement of the blind, the compensation springs (103) are unloaded , contributing significantly to the lifting force of the blind exerted by the gear motor (104).
Estos tipos de sistemas utilizados para enrollar y desenrollar persianas tiene deficiencias debido a algunos inconvenientes.These types of systems used to wind and unwind blinds have deficiencies due to some inconveniences.
La longitud y el diametro de la barra de soporte (101), el numero y el diametro de las cajas con muelle de retencion (102), la longitud y el espesor de las correas de acero utilizadas para fabricar los muelles en espiral (103), la potencia del motor de engranajes (104) y el diametro de la polea (140) vanan segun la anchura y el peso de la persiana. En consecuencia, para satisfacer los diversos requerimientos de un cliente, el fabricante de persianas enrollables debe almacenar grandes existencias de los diferentes componentes en el almacen.The length and diameter of the support bar (101), the number and diameter of the boxes with retaining spring (102), the length and thickness of the steel belts used to make the spiral springs (103) , the power of the gear motor (104) and the diameter of the pulley (140) are according to the width and weight of the blind. Consequently, to satisfy a client's various requirements, the manufacturer of roller blinds must store large stocks of the different components in the warehouse.
Tambien el montaje de la persiana es bastante complicado. El ensamblaje preve el montaje de todas las cajas con muelle de retencion (102) a lo largo de la barra de soporte (101), el montaje del motor de engranajes (4) sobre la barra de soporte (101) y la fijacion del borde superior (5a) de la persiana (5) a la polea (140) y a la carcasa de todas las cajas con muelle de retencion (102).Also the assembly of the blind is quite complicated. The assembly provides for the assembly of all the boxes with retention spring (102) along the support bar (101), the assembly of the gear motor (4) on the support bar (101) and the fixing of the edge upper (5a) of the blind (5) to the pulley (140) and to the housing of all the boxes with retention spring (102).
Los inconvenientes adicionales se refieren a la seguridad de los operarios encargados de montar la persiana o de repararla y mantenerla despues de su instalacion. De hecho, las cajas de muelle de retencion (102) necesitan ser manejadas con gran cuidado y habilidad, especialmente cuando los muelles de compensacion (103) estan cargados con su carga maxima o parcial. De hecho, las correas de acero de los muelles de compensacion (103) se convierten en afiladas cuchillas que pueden ser extremadamente peligrosas si se desenrollan libre e incontrolablemente debido a una falla accidental o si sus extremos se liberan de los puntos de fijacion. Hay que senalar que los muelles en espiral tienden a salirse de su caja, convirtiendose en objetos punzantes extremadamente peligrosos.Additional inconveniences relate to the safety of the operators responsible for mounting the blind or for repairing and maintaining it after installation. In fact, the retention spring boxes (102) need to be handled with great care and skill, especially when the compensation springs (103) are loaded with their maximum or partial load. In fact, the steel belts of the compensation springs (103) become sharp blades that can be extremely dangerous if they are unrolled freely and uncontrollably due to an accidental failure or if their ends are released from the fixing points. It should be noted that spiral springs tend to get out of their box, becoming extremely dangerous sharp objects.
El documento CH688006 describe un dispositivo de accionamiento de persianas enrollables que comprende un tubo de enrollado dentro del cual estan montados un motor de engranajes y un muelle en espiral. La persiana se fija al tubo de enrollado que hace girar el motor electrico para enrollar la persiana enrollable en el tubo de enrollado. Tal dispositivo no es versatil. De hecho, la longitud del tubo de enrollado debe ser la misma que la anchura de la persiana enrollable. En vista de lo anterior, el operario debe almacenar una pluralidad de dispositivos en el almacen, con tubos de enrollado de diferente longitud de acuerdo con la anchura de las persianas enrollables.Document CH688006 describes a roller blind drive device comprising a winding tube into which a gear motor and a spiral spring are mounted. The blind is fixed to the winding tube that rotates the electric motor to wind the roller blind in the winding tube. Such a device is not versatile. In fact, the length of the winding tube must be the same as the width of the roller blind. In view of the above, the operator must store a plurality of devices in the warehouse, with winding tubes of different lengths according to the width of the roller blinds.

El documento DE4211940 describe un dispositivo de accionamiento para persianas enrollables similar al del documento CH688006 en el que un tubo de enrollado aloja tanto un motor de engranajes asf como un muelle en espiral. Sin embargo, el dispositivo del documento DE4211940 no esta provisto de un sistema para ajustarse a la anchura de la persiana enrollable o la anchura de la abertura de la ventana.Document DE4211940 describes a drive device for roller blinds similar to that of document CH688006 in which a winding tube houses both a gear motor as well as a spiral spring. However, the device of document DE4211940 is not provided with a system to adjust to the width of the roller shutter or the width of the window opening.
El documento CH206381 describe un dispositivo habitual de enrollado para persianas enrollables y un sistema de fijacion para ajustar el dispositivo a las pequenas variaciones dimensionales causadas por una fabricacion defectuosa. Tal sistema de fijacion proporciona soportes en forma de U que comprenden dos patas que estan acopladas con holgura en orificios realizados en la pared de mampostena. Los soportes estan fijados a una brida conectada al dispositivo de enrollado. Tal sistema de fijacion permite un ajuste vertical y horizontal de unos pocos milfmetros pero no es capaz de ajustarse a la anchura de las diferentes persianas enrollables que pueden diferir en uno pocos metros.Document CH206381 describes a usual winding device for roller blinds and a fixing system to adjust the device to small dimensional variations caused by a defective manufacturing. Such a fixing system provides U-shaped brackets comprising two legs that are loosely coupled in holes made in the masonry wall. The supports are fixed to a flange connected to the winding device. Such a fixing system allows a vertical and horizontal adjustment of a few millimeters but is not able to adjust to the width of the different roller blinds that can differ by a few meters.
El documento US2013/0333848 describe un conjunto de un tubo con motor que tiene una longitud inferior a la longitud de un tubo exterior de rodillo para dedicarlo a una sombra. El conjunto de un tubo con motor gira por medio de un motor de accionamiento. El conjunto de tubo con motor comprende muelles de contrapeso. El conjunto de tubo con motor comprende un eje de salida extendido conectado a una tapa de extremo y un eje de muelle extendido conectado a un cojinete de soporte en el extremo, con el fin de adaptar la longitud del tubo con motor a la longitud del tubo exterior de rodillo.Document US2013 / 0333848 describes an assembly of a motorized tube that is less than the length of an outer roller tube for dedication to a shadow. The assembly of a motor tube rotates by means of a drive motor. The engine tube assembly comprises counterweight springs. The motorized tube assembly comprises an extended output shaft connected to an end cap and an extended spring shaft connected to a support bearing at the end, in order to adapt the length of the motorized tube to the length of the tube roller exterior
El proposito de la presente invencion es remediar los inconvenientes de la tecnica anterior, proporcionando un dispositivo de accionamiento motorizado y de soporte para persianas enrollables, que sea versatil y utilizable con cualquier anchura de la persiana o de la abertura que se cubra con la persiana.The purpose of the present invention is to remedy the drawbacks of the prior art, by providing a motorized drive and support device for roller blinds, which is versatile and usable with any width of the blind or of the opening that is covered with the blind.
El primer proposito de la invencion es proporcionar un dispositivo de accionamiento motorizado y de soporte para persianas enrollables que permita a un fabricante de persianas enrollables cumplir con los requisitos mas diversos utilizando el mismo componente normalizado, con la consecuente simplificacion y ahorro en terminos de inventarios en su almacen.The first purpose of the invention is to provide a motorized drive and roller blind support device that allows a manufacturer of roller blinds to meet the most diverse requirements using the same standardized component, with the consequent simplification and savings in terms of inventories in your store
Un proposito adicional de la invencion es proporcionar un dispositivo que logre que la instalacion de la persiana sea mas facil y mas segura.An additional purpose of the invention is to provide a device that makes the installation of the blind easier and safer.
Estos propositos se consiguen mediante el dispositivo de la invencion, cuyas caractensticas se describen en las reivindicaciones adjuntas.These purposes are achieved by the device of the invention, the features of which are described in the appended claims.
Otro objetivo de la invencion es proporcionar un dispositivo en el que el tubo giratorio no este sometido a una gran tension de torsion. Dicho objetivo se consigue mediante el dispositivo segun la reivindicacion independiente 1.Another object of the invention is to provide a device in which the rotating tube is not subjected to great torsional stress. Said objective is achieved by the device according to independent claim 1.
El dispositivo de la invencion comprende un conjunto de enrollado, que esta provisto y pre ensamblado tanto con un motor de engranajes como con un conjunto de muelle de compensacion utilizado para equilibrar el peso de la persiana.The device of the invention comprises a winding assembly, which is provided and pre-assembled with both a gear motor and a compensation spring assembly used to balance the weight of the blind.
El conjunto de enrollado comprende una carcasa giratoria con eje horizontal y conectores de acoplamiento rapido colocados en el extremo del conjunto de enrollado para acoplar dos barras de soporte.The winding assembly comprises a rotating housing with a horizontal axis and quick coupling connectors placed at the end of the winding assembly to couple two support bars.
La carcasa giratoria aloja un bastidor de soporte utilizado para soportar un motor de engranajes adaptado para hacer una polea con eje horizontal, que esta fijada a la carcasa giratoria. El borde superior la persiana esta fijado a la carcasa giratoria y la persiana esta sostenida y accionada por la carcasa giratoria, que tambien actua como tambor enrollador para todo la persiana.The rotating housing houses a support frame used to support a gear motor adapted to make a pulley with a horizontal axis, which is fixed to the rotating housing. The upper edge of the blind is fixed to the rotating housing and the blind is supported and actuated by the rotating housing, which also acts as a roller drum for the entire blind.
La carcasa giratoria tambien aloja el conjunto de muelle de compensacion, compuesto por muelles de torsion helicoidales con extremos unidos a una parte fija y a una parte giratoria del conjunto de enrollado, respectivamente.The rotating housing also houses the compensation spring assembly, consisting of helical torsion springs with ends attached to a fixed part and a rotating part of the winding assembly, respectively.
El motor de engranajes comprende un eje de accionamiento conectado a la polea fijada a la carcasa giratoria. El conjunto de muelle de compensacion comprende un primer extremo fijado al bastidor fijo y un segundo extremo conectado a la polea. De esta manera, la caja giratoria no esta sometida a un alto esfuerzo de torsion.The gear motor comprises a drive shaft connected to the pulley fixed to the rotating housing. The compensation spring assembly comprises a first end fixed to the fixed frame and a second end connected to the pulley. In this way, the rotating box is not subjected to a high torque.
Durante la rotacion de la polea en la direccion que corresponde al desplazamiento descendente de la persiana, el conjunto de muelle de compensacion esta sometido a una tension de torsion y acumula energfa que, durante el desplazamiento ascendente de la persiana, contribuye a la fuerza de elevacion de la persiana ejercida por el motor de engranajes.During the rotation of the pulley in the direction corresponding to the downward displacement of the blind, the compensation spring assembly is subjected to a torsional tension and accumulates energy which, during the upward displacement of the blind, contributes to the lifting force of the blind exerted by the gear motor.
Despues de haber sido informado de las dimensiones la persiana que se va a instalar, el operario encargado de preparar y montar la persiana simplemente necesita cortar dos secciones identicas de barraAfter being informed of the dimensions of the blind to be installed, the operator in charge of preparing and assembling the blind simply needs to cut two identical sections of bar

para dimensionarlas e insertarlas desde lados opuestos en los conectores de acoplamiento rapido fijados al conjunto de enrollado .to size and insert them from opposite sides in the quick coupling connectors attached to the winding assembly.
Evidentemente, la longitud de las secciones de barra debe ser identica a la longitud total de la persiana, despues de restar la longitud del conjunto de enrollado que esta dispuesto entre las dos secciones de barra.Obviously, the length of the bar sections must be identical to the total length of the blind, after subtracting the length of the winding assembly that is arranged between the two bar sections.
A continuacion, el operario debe fijar el borde superior la persiana sobre la carcasa giratoria del conjunto de enrollado.Next, the operator must fix the upper edge of the blind on the rotating housing of the winding assembly.
En cuanto a la prevencion de accidentes, los muelles helicoidales del conjunto de muelle de compensacion son mucho mas seguros que los muelles en espiral contenidos en las cajas de muelle de retencion utilizadas en la tecnica anterior. De hecho, en el caso de una falla en un muelle, los muelles helicoidales estan contenidos y protegidos dentro de la carcasa giratoria y enrollados dentro de una camisa de sujecion del muelle que los soporta.As for accident prevention, the coil springs of the compensation spring assembly are much safer than the spiral springs contained in the retention spring boxes used in the prior art. In fact, in the case of a spring failure, the coil springs are contained and protected within the rotating housing and rolled into a spring support sleeve that supports them.

Las dos barras de soporte (1) se obtienen de vez en cuando cortando dos secciones de barra de identico tamano, partiendo de una barra larga con una longitud estandar. En vista de lo anterior, un fabricante de persianas enrollables puede almacenar una cantidad adecuada de barras largas con longitud estandar en el almacen. Debe tenerse en cuenta que la longitud del conjunto de enrollado (10) es considerablemente inferior con respecto a la anchura de la persiana (5) y consecuentemente a la anchura de la abertura que recibe la persiana (5). La diferencia entre la longitud del conjunto de enrollado (10) y la anchura la persiana (5) es compensada por la longitud de las barras de soporte (1).The two support bars (1) are obtained from time to time by cutting two sections of identical size bar, starting from a long bar with a standard length. In view of the above, a manufacturer of roller blinds can store an adequate amount of long bars with standard length in the warehouse. It should be noted that the length of the winding assembly (10) is considerably shorter with respect to the width of the blind (5) and consequently to the width of the opening received by the blind (5). The difference between the length of the winding assembly (10) and the width of the blind (5) is compensated by the length of the support bars (1).
Por lo tanto, el fabricante de persianas enrollables puede mantener un inventario de muestras solo para los dos siguientes componentes estandar:Therefore, the manufacturer of roller blinds can maintain an inventory of samples only for the following two standard components:
- para el conjunto de enrollado (10);- for the winding assembly (10);
- para la barra de longitud estandar utilizada para cortar las barras de soporte (1) que van a ser asociadas de vez en cuando con el conjunto de enrollado (10).- for the standard length bar used to cut the support bars (1) that will be associated from time to time with the winding assembly (10).
