Contera perfeccionada para ejes de persianas motorizadas.Contera perfected for blind shafts motorized

Object of the invention

La presente invención, según lo expresa el enunciado de esta memoria descriptiva, se refiere a una contera perfeccionada para ejes de persianas motorizadas, la cual presenta notables características relevantes y ventajas técnicas frente a las conteras convencionales que están destinadas a ser incorporadas a los tubos de sección poligonal y preferentemente octogonal, en los que se enrolla la persiana y tanto si su accionamiento es manual como motorizado.The present invention, as expressed by the set forth in this specification, refers to a count perfected for motorized blind shafts, which features notable relevant characteristics and technical advantages over conventional beams that are intended to be incorporated to the pipes of polygonal section and preferably octagonal, in those who roll up the blind and whether its operation is Manual as motorized.

Es un objeto de la invención el presentar una contera notablemente reforzada para su uso en persianas motorizadas que son más pesadas, solucionando así las constantes averías que a causa de una mala contera se producen convencionalmente.It is an object of the invention to present a Contains remarkably reinforced for use in motorized blinds which are heavier, thus solving the constant breakdowns that Cause of a bad count occur conventionally.

Naturalmente que en el caso de utilizar persianas motorizadas, es decir, cuando el accionamiento se consigue a través de un motor eléctrico incorporado en uno de los extremos del eje de arrollamiento de la persiana, el motor ofrece una espiga de sección cuadrada o de cualquier otra sección, destinada a fijarse en el testero correspondiente de la caja de persiana, lo que tiene lugar a través de diferentes sistemas. La contera que la invención propone está destinada especialmente para su montaje en el extremo del eje tubular de la persiana, opuesto al portador del motor de accionamiento.Of course, in the case of using motorized blinds, that is, when the drive is get through an electric motor built into one of the Shaft winding shaft ends, the motor offers a square section spike or any other section, intended to be fixed in the corresponding tester of the box of shutter, which takes place through different systems. The note that the invention proposed is especially intended for its mounting on the end of the tubular axis of the blind, opposite the drive motor carrier.

Background of the invention

Actualmente las conteras que se montan en los ejes de persianas motorizadas, disponen de una porción tubular prismática de sección normalmente octogonal con una valona extrema de tope de introducción en la correspondiente embocadura del tramo tubular que define el eje de arrollamiento de la persiana. Una vez insertada la contera, la misma presenta una espiga coaxial emergente que ha de introducirse en un alojamiento correspondiente previsto en el testero de la caja de la persiana, en el que previamente se ha dispuesto un rodamiento adecuado al diámetro de la espiga. En lugar de existir en la contera una espiga cilíndrica, la misma puede presentar un alojamiento coaxial receptor de un rodamiento en el que se introducirá la espiga que emerge en este caso del testero, siendo indistinto el montaje de uno u otro tipo.Currently you count them that are mounted on the motorized blind shafts, have a tubular portion prismatic section normally octagonal with an extreme wall of stop of introduction in the corresponding mouth of the section tubular defining the winding axis of the blind. One time inserted the container, it has a coaxial spike pop-up to be introduced in a corresponding accommodation provided in the front of the blind box, in which previously a bearing adapted to the diameter of the spike. Instead of having a spike in it cylindrical, it can have a coaxial housing receiver of a bearing in which the pin will be inserted that in this case the tester emerges, the assembly of One or another type.

Estas conteras convencionales tienen una pared tubular de poco espesor y con pocos refuerzos, por lo que se desgastan fácilmente al no resistir el propio peso del eje de la persiana y el peso de ésta, ante los constantes esfuerzos de rotación en uno y otro sentidos, a los que se ve sometida.These conventional tips have a wall tubular of little thickness and with few reinforcements, so wear easily by not resisting the axle's own weight shutter and the weight of it, given the constant efforts of rotation in both directions, to which it is subjected.

Description of the invention

En líneas generales, la contera perfeccionada para ejes de persianas motorizadas, objeto de la presente invención, aún siendo del tipo convencional puesto que ha de tener una configuración tubular poligonal adaptada al interior del tubo que materializa el eje de la persiana y contar con la espiga o el alojamiento para el rodamiento de anclaje al testero de la caja de persiana, presenta una estructura muy reforzada en toda la longitud de la contera.In general, the perfected count for motorized roller shafts, object of the present invention, still being of the conventional type since it has to have a polygonal tubular configuration adapted to the inside of the tube that materialize the axis of the blind and have the spike or the housing for the anchor bearing to the end of the box blind, has a very reinforced structure throughout the length of the count.

En proximidad a la valona o resalte perimetral de tope de introducción en la embocadura del tubo de la persiana, presenta un tabique transversal a cuyos costados existen sendos tramos tubulares coaxiales que se unen a las paredes de la porción tubular prismática de sección octogonal, u otra, mediante una serie de tabiques radiales uniformemente distribuidos en sentido angular, lo que otorga una gran robustez a la contera. Existen además unos nervios longitudinales adosados a las paredes internas de la porción tubular prismática y concretamente en las líneas medias de sus caras, precisamente donde roscan los tornillos de amarre que atraviesan el tubo y roscan en la contera para fijar e inmovilizar la longitud del eje de arrollamiento. Gracias a estos nervios que no es necesario que tengan toda la longitud de la contera ya que en la zona inicial de introducción las paredes normalmente se ahusan para facilitar la entrada en el tubo, nunca se reciben los tornillos de sujeción.In proximity to the wall or perimeter projection of stopper of introduction in the mouth of the shutter tube, It presents a transverse septum at whose sides there are two coaxial tubular sections that join the portion walls Prismatic tubular octagonal section, or other, by a series of radial partitions evenly distributed angularly, which gives great strength to the count. There are also some longitudinal nerves attached to the inner walls of the portion tubular prismatic and specifically in the midlines of their faces, precisely where the tie screws screw cross the tube and thread on the end to fix and immobilize the length of the winding shaft. Thanks to these nerves that it is not necessary that they have the entire length of the bead since in the initial introduction zone the walls normally taper to facilitate entry into the tube, you never receive clamping screws

En la parte más externa de la contera, es decir, al otro lado del tabique transversal comentado, el tramo tubular coaxial que también está reforzado con tabiques radiales, lo está pero con mayor número de ellos para optimizar el refuerzo.In the outermost part of the count, that is, on the other side of the commented transverse septum, the tubular section coaxial that is also reinforced with radial partitions, it is but with more number of them to optimize the reinforcement.

Para conseguir el tipo de contera provisto de una espiga cilíndrica, el tramo tubular coaxial exterior se prolonga en la espiga de inserción en el soporte correspondiente del testero.To get the type of account provided with a cylindrical pin, the outer coaxial tubular section is prolongs the insertion pin in the corresponding support of the testero.

Si la contera está destinada a recibir el rodamiento en el que ha de insertarse la espiga que emerge del testero de la caja de persiana, el aludido tramo tubular de este lado respecto al tabique transversal, se construye con un diámetro ajustado al diámetro exterior del rodamiento que ha de montarse en él, habiéndose previsto además que como tope de introducción de este rodamiento exista un corto cuello coaxial interior a dicho tramo tubular y que a su vez está reforzado con otros tabiquillos radiales tendidos entre sus paredes cilíndricas.If the account is intended to receive the bearing in which the pin emerging from the front of the blind box, the aforementioned tubular section of this side with respect to the transverse septum, it is constructed with a diameter adjusted to the outer diameter of the bearing to be mounted on he, having also foreseen that as an introduction cap for this bearing exists a short inner coaxial neck to said tubular section and which in turn is reinforced with other partitions radial lying between its cylindrical walls.

La invención prevé también una misma contera que puede ser utilizada para ambos tipos de montaje, es decir que esté provista de la espiga o que incluya el rodamiento, sin más que prever axialmente unos medios de soporte para un eje que pueda montarse y desmontarse por constituir una pieza adicional, pero de forma que dicho eje esté privado de rotación en su alojamiento. Para ello y como elemento de refuerzo en su estructura, el conducto tubular coaxial del lado interior de la contera respecto del tabique diametral, tiene sección poligonal y preferentemente cuadrada para recibir por deslizamiento un eje de idéntica sección, preferentemente cuadrada por ser la más convencional, aunque también puede emplearse cualquier otra sección que no sea circular para evitar el giro relativo entre estos elementos. El extremo del eje se remata en la espiga cilíndrica que emerge al exterior, estando asistido este eje por un resorte previamente introducido, el cual le impulsa hacia la posición de emergencia al establecer apoyo dicho resorte en una tapa o pestaña interna del conducto tubular que cierra su embocadura.The invention also provides the same account as It can be used for both types of mounting, that is provided with the spike or including the bearing, without more than axially provide support means for an axis that can assemble and disassemble by constituting an additional piece, but of so that said axis is deprived of rotation in its housing. For this and as a reinforcing element in its structure, the conduit coaxial tubular of the inner side of the end with respect to the diametral septum, has polygonal section and preferably square to receive by sliding an axis of identical section, preferably square for being the most conventional, although any other section that is not circular can also be used to avoid the relative rotation between these elements. The end of shaft is topped on the cylindrical spike that emerges to the outside, this axis being assisted by a spring previously introduced, which drives you to the emergency position when setting support said spring in a cover or inner flange of the duct tubular that closes its mouth.

Ventajosamente y como aumento de resistencia como es el objetivo principal de la invención, a partir del tabique transversal, en lugar de formarse el conducto tubular correspondiente al diámetro del exterior del rodamiento, en el mismo proceso de inyección de la contera se sitúa en esta zona un inserto metálico con un orificio poligonal de idéntica sección que el eje cuadrado que le atraviesa.Advantageously and as resistance increase as is the main objective of the invention, from the partition transverse, instead of forming the tubular duct corresponding to the diameter of the outside of the bearing, in the same injection process is located in this area a metallic insert with a polygonal hole of identical section that the square axis that crosses it.

El eje de sección poligonal deslizante en la contera ha de ser fijado en su alojamiento para evitar que pueda perderse durante su almacenamiento y transporte, lo cual se consigue preferentemente al incorporar un tornillo de tipo allen en disposición radial al inserto de forma que su extremo llegue a contactar con la periferia del eje poligonal.The axis of polygonal section sliding in the It has to be fixed in your accommodation to prevent get lost during storage and transportation, which is preferably achieved by incorporating an Allen screw in radial arrangement to the insert so that its end reaches contact the periphery of the polygonal axis.

También se consigue el mismo fin si el eje poligonal dispone en el extremo interno de una espiga cilíndrica en la que se sujeta el resorte y estando éste introducido ajustadamente en su otro extremo al ser las paredes ligeramente troncopiramidades en esta zona del extremo interno de la contera.The same end is also achieved if the axis polygonal disposes at the inner end of a cylindrical pin in the one that holds the spring and being inserted tightly at its other end being the walls slightly trunks in this area of the inner end of the tip.

Description of the preferred embodiments

Haciendo referencia a la numeración adoptada en las figuras, podemos ver cómo la contera perfeccionada para ejes de persianas motorizadas que la invención propone, tal como se muestra en las figuras 1 a 4 cuenta como otras de su tipo con una porción tubular 1 de sección octogonal para acoplarse en la embocadura correspondiente del eje tubular de igual sección sobre el que se enrollará la persiana, dotado de una valona 2 o regruesado perimetral como tope de introducción.Referring to the numbering adopted in the figures, we can see how the perfected count for axes of motorized blinds that the invention proposes, as shown in figures 1 to 4 counts as others of its kind with a tubular portion 1 of octagonal section to engage in the corresponding mouthpiece of the tubular shaft of the same section on who will roll up the blind, equipped with a wall 2 or perimeter return as an introduction stop.

Una de las características mejoradas de la invención la determina el hecho de que en proximidad al extremo provisto de la valona 2 de tope, existe un tabique transversal 3 del que parten coaxialmente a uno y otro lado del mismo sendos tramos tubulares 4 y 5 que pueden ser del mismo diámetro o diferente y carecer o no de la zona discoidal que obture el ánima, y que en este caso son del mismo diámetro y no existe dicha zona discoidal. Ambas porciones se soportan respectivamente en tabiques radiales 6 y 7 de refuerzo y preferentemente en mayor número los de la zona exterior o pertenecientes al tramo tubular 5, ubicados todos en este ejemplo en correspondencia con las líneas centrales de las caras del contorno poligonal.One of the improved features of the invention is determined by the fact that in proximity to the end provided with the stop wall 2, there is a transversal partition 3 from which they leave coaxially on both sides of the same two tubular sections 4 and 5 that can be of the same diameter or different and lack or not of the discoidal zone that clears the soul, and that in This case is of the same diameter and there is no such discoidal zone. Both portions are supported respectively on radial partitions 6 and 7 reinforcement and preferably in greater numbers those in the area outside or belonging to tubular section 5, all located in this example in correspondence with the central lines of the polygonal contour faces.

Además, para reforzar la pared de la porción tubular 1 en las zonas de posible ubicación de los tornillos de fijación del eje de la persiana a la contera como es habitual, se han previsto unos nervios longitudinales 8 con los que se incrementa el espesor de la contera para recibir mayor número de hilos de rosca del tornillo y aumentar con ello la sujeción de la contera al tubo, ya que como hemos dicho anteriormente los ejes de persianas motorizados son notablemente más pesados que los utilizados cuando el accionamiento es manual mediante cinta y polea de enrollamiento.In addition, to reinforce the portion wall tubular 1 in the areas of possible location of the screws fixing the axis of the blind to the counting as usual, it have provided longitudinal ribs 8 with which Increase the thickness of the container to receive a greater number of screw threads and thereby increase the clamping of the count the tube, since as we have said previously the axes of Motorized blinds are noticeably heavier than those used when the drive is manual by belt and pulley of curl

En las figuras 1 y 4 a las que estamos haciendo referencia, la contera está provista de la espiga 9 coaxial al tramo tubular 5 y tiene menor diámetro que éste. Esta contera con espiga 9 está referenciada en general con el número 10 en estas figuras 1 a 4.In figures 1 and 4 we are doing reference, the end piece is provided with pin 9 coaxial to tubular section 5 and has a smaller diameter than this. This one with pin 9 is generally referenced with the number 10 in these Figures 1 to 4.

En las figuras 5 a 8 se representa una contera 11 que a diferencia de la anterior contera 10 está provista de un alojamiento 12 para recibir un rodamiento 13 (figura 5) que hace tope en el cuello tubular 14 coaxial interior que además está reforzado con otros pequeños tabiques radiales 15. Este alojamiento 12 lo forma el tramo tubular 5' que es de mayor diámetro que el tramo tubular 5 referido.In figures 5 to 8 a piece is shown 11 which, unlike the previous one, counts 10 is provided with a housing 12 to receive a bearing 13 (figure 5) which makes stop on the inner coaxial tubular neck 14 which is also reinforced with other small radial partitions 15. This accommodation 12 is formed by the 5 'tubular section that is larger in diameter than the tubular section 5 referred.

Por último, en las figuras 9 a 12 se representa una contera mixta 16 que puede por tanto ser utilizada como contera con espiga 9 o como contera con alojamiento 1 para recibir un rodamiento 13 (ver figura 5). Para ello, la porción tubular 4' es de sección cuadrada para recibir un eje 17 de idéntica sección cuadrada que puede desplazarse linealmente pero no rotacionalmente, estando asistido por un resorte interno 18. El eje 17 recorre axialmente la contera 16, atraviesa el tabique transversal 3 y pasa también por un inserto metálico 19 montado en el mismo proceso de inyección del material plástico de la contera 16, ubicado en un regruesado interno del tramo tubular 5', siendo dicho inserto metálico 19 un perfecto elemento de refuerzo.Finally, in figures 9 to 12 it is represented a mixed count 16 that can therefore be used as count with pin 9 or as count with accommodation 1 to receive a bearing 13 (see figure 5). For this, the tubular portion 4 'is square section to receive an axis 17 of identical section square that can move linearly but not rotationally, being assisted by an internal spring 18. The axis 17 runs axially the bottom 16, crosses the transverse partition 3 and passes also by a metal insert 19 mounted in the same process of injection of the plastic material of the container 16, located in a internal return of the tubular section 5 ', said insert being Metallic 19 a perfect reinforcing element.

El eje cuadrado 17 emerge al exterior en un amplio tramo y en su extremo está conformada la espiga 9 cilíndrica, teniendo una longitud emergente que posibilita que el eje de arrollamiento de la persiana pueda desplazarse linealmente en contra del resorte 18, introduciéndose la porción emergente del eje cuadrado en el interior de su contera y quedando libre el extremo del eje de arrollamiento de la persiana donde está el motor y por tanto su espiga se sale del alojamiento del testero. Así se desmonta fácilmente el eje de la persiana y puede repararse el motor o cualquier otro elemento.The square axis 17 emerges to the outside in a wide section and at its end the pin 9 is shaped cylindrical, having an emerging length that allows the roller winding axis can move linearly against spring 18, the emerging portion of the square axis inside its counting and leaving the end of the roller winding shaft where the motor is and therefore his spike leaves the housing of the testero. Thus Easily disassemble the shaft of the blind and can repair the Engine or any other item.

Para sujetar el eje 17 y que no se salga durante el tiempo de almacenamiento, transporte y suministro de estas piezas, se prevé un tornillo radial 20 tipo allen roscado en el inserto 19 y en el tramo tubular 5', siendo accesible desde el exterior (figura 11). Su extremo activo presiona el eje 17 cuadrado, o invade frontalmente el escalonamiento que define el nacimiento de la espiga cilíndrica 9, quedando perfectamente retenido.To hold shaft 17 and not to go out during the storage, transport and supply time of these pieces, a radial screw 20 type Allen threaded in the insert 19 and in the tubular section 5 ', being accessible from the exterior (figure 11). Its active end presses axis 17 square, or frontally invades the staggering that defines the birth of the cylindrical pin 9, being perfectly detained.

También está previsto con este mismo fin de retención del eje 17 evitando que se pierda o se salga de su alojamiento, que el propio resorte 18 quede fijado en una espiga interna 21 de este eje 17 bloqueándose en las paredes ahusadas de la zona extrema de la porción tubular 4' en la zona contigua a la pestaña que retiene el resorte.It is also planned for the same purpose of axis 17 retention preventing it from getting lost or out of its housing, that the spring 18 itself is fixed on a pin internal 21 of this axis 17 blocking in the tapered walls of the end zone of the tubular portion 4 'in the area adjacent to the tab that retains the spring.
