DESCRIPCIONDESCRIPTION
Dispositivo tensor para un toldo extensible desde un arbol de enrollamiento Campo tecnicoTensioning device for an extensible awning from a winding shaft Technical field
La invencion se refiere a un dispositivo tensor para un toldo extensible desde un arbol de enrollamiento con un cable tensor solicitado por al menos un resorte, en el que el resorte esta configurado como resorte de gas para tensar el almacenamiento de cable, que presenta dos conjuntos de rodillos tensores desplazables unos con respecto a otros con ayuda del resorte de gas para el cable tensor guiado en vaiven formando bucles entre los conjuntos de rodillos tensores.The invention relates to a tensioning device for an extensible awning from a winding shaft with a tensioning cable requested by at least one spring, in which the spring is configured as a gas spring to tension the cable storage, which has two sets of tension rollers movable with respect to each other with the help of the gas spring for the guided tension cable in vaiven forming loops between the sets of tension rollers.
Estado de la tecnicaState of the art
Para enrollar un toldo, que esta conectado a lo largo de una llnea de separacion con un arbol de enrollamiento y que puede extenderse desde el arbol de enrollamiento en sentidos contrarios tirando de los extremos dirigidos hacia fuera desde la llnea de separacion, de una manera facil sobre el arbol de enrollamiento y extenderlo a partir del mismo. Se conoce (documento EP 0 865 557 B1), dotar el arbol de enrollamiento de un accionamiento y guiar de vuelta los cables de traccion que se necesitan para la extension del toldo, que se enganchan en los extremos dirigidos hacia fuera desde la llnea de separacion del toldo, a lo largo de rodillos de desviacion hasta el arbol de enrollamiento y fijarlos sobre los rodillos de enrollamiento conectados de manera resistente al giro con el arbol de enrollamiento, de modo que en el caso de un giro del arbol de enrollamiento en el sentido del desenrollamiento el toldo se extiende con ayuda de los cables de traccion que se enrollan sobre los rodillos de enrollamiento a modo de almacenamiento de cable desde el arbol de enrollamiento, concretamente en la medida de su desenrollamiento desde el arbol de enrollamiento. Para compensar eventuales diferencias de longitud y para tensar el toldo, estan previstos dispositivos tensores, que presentan una pretension de resorte, entre los cables de traccion. Sin embargo, en esta clase de toldos que pueden enrollarse y desenrollarse, una desventaja consiste en los costes de construccion considerables generados por el guiado de vuelta adicional de los cables de traccion hasta el arbol de enrollamiento y los dispositivos tensores previstos entre los cables de traccion guiados de vuelta. Ademas no es suficiente el arriostramiento de resorte de los cables de traccion dado por el dispositivo tensor para proteger la construccion de carga y el toldo de una sobrecarga por ejemplo por rafagas de viento o precipitaciones. A esto se le anade que el arbol de enrollamiento con el accionamiento para enrollar y desenrollar el toldo debe configurarse suficientemente rlgido a la flexion, lo que en el caso de una limitacion correspondiente del diametro del arbol de enrollamiento conduce a una limitacion del tamano del toldo.To wind a canopy, which is connected along a separation line with a winding shaft and which can extend from the winding shaft in opposite directions by pulling the ends directed outward from the separation line, in an easy way on the winding tree and extend it from it. It is known (EP 0 865 557 B1), to provide the winding shaft of a drive and to guide back the traction cables that are needed for the extension of the awning, which are hooked at the ends directed outwards from the separation line from the awning, along deflection rollers to the winding shaft and fix them on the winding rollers connected in a resistant manner to the winding shaft, so that in the case of a rotation of the winding shaft in the direction From the unwind the awning is extended with the help of the traction cables that are wound on the winding rollers as a cable storage from the winding shaft, specifically to the extent of its unwinding from the winding tree. To compensate for possible differences in length and to tension the awning, tensioning devices are provided, which have a spring pretension, between the traction cables. However, in this class of awnings that can be rolled and unwound, a disadvantage consists in the considerable construction costs generated by the additional return guidance of the traction cables to the winding shaft and the tensioning devices provided between the traction cables guided back. In addition, the spring bracing of the traction cables given by the tensioning device is not sufficient to protect the load construction and the awning from an overload, for example by gusts of wind or precipitation. To this it is added that the winding shaft with the drive for winding and unwinding the awning must be sufficiently rigid to bending, which in the case of a corresponding limitation of the diameter of the winding shaft leads to a limitation of the awning size .
Para conseguir condiciones de construccion ventajosas en el caso de marquesinas para dar sombra a superficies de ventanas trapeciales o triangulares con un arbol de enrollamiento dotado de un accionamiento dispuesto a lo largo de un canto inferior para la lona de marquesina que puede desenrollarse hacia arriba con una punta adelantada sobre un cable de traccion, ya se conoce (documento DE 197 06 251 A1), esta previsto conectar a lo largo de los cantos laterales inclinados unos hacia otros resortes de gas dispuestos en carriles longitudinales, que se gulan por medio de cables de traccion, a modo de aparejos sobre rodillos de desviacion en el extremo fijo superior de los resortes de gas, con la punta de la lona de marquesina. Sin embargo, con ayuda de los resortes de gas no es posible un accionamiento del arbol de enrollamiento en el sentido del enrollamiento.To achieve advantageous construction conditions in the case of canopies to shade trapezoidal or triangular window surfaces with a winding shaft provided with a drive arranged along a lower edge for the canopy tarp that can be unwound upwards with a advanced tip on a traction cable, already known (document DE 197 06 251 A1), it is planned to connect along the side edges inclined towards other gas springs arranged in longitudinal rails, which are guided by means of cables traction, by way of rigging on deflection rollers at the upper fixed end of the gas springs, with the tip of the canopy tarp. However, with the help of gas springs, it is not possible to drive the winding shaft in the direction of winding.
Exposicion de la invencionExhibition of the invention
Por tanto, la invencion se basa en el objetivo de configurar un dispositivo tensor para un toldo del tipo descrito al inicio de manera que permite un buen arriostramiento del toldo a lo largo de la longitud de extraction completa y conlleva el requisito de hacerse eficaz en el sentido del enrollamiento.Therefore, the invention is based on the objective of configuring a tensioning device for a canopy of the type described at the beginning so as to allow a good bracing of the awning along the entire extraction length and entails the requirement of becoming effective in the winding direction
La invencion soluciona el objetivo planteado, de tal manera que el resorte de gas esta dispuesto con el almacenamiento de cable en un soporte tubular, que el cable tensor se engancha a un rodillo de enrollamiento para el cabo de cable tensor, conectado mediante accionamiento con el arbol de enrollamiento, dispuesto en el extremo superior del soporte tubular, cuyo arbol perpendicular al eje de soporte atraviesa el soporte tubular o un soporte de cojinete para el rodillo de enrollamiento y esta conectado mediante accionamiento con el arbol de enrollamiento.The invention solves the stated objective, in such a way that the gas spring is arranged with the cable storage in a tubular support, that the tensioning cable is hooked to a winding roller for the tensioning cable end, connected by actuation with the winding shaft, arranged at the upper end of the tubular support, whose shaft perpendicular to the support shaft crosses the tubular support or a bearing support for the winding roller and is connected by drive with the winding shaft.
Dado que se emplea un cable tensor guiado sobre un almacenamiento de cable y el almacenamiento de cable esta pretensado en resorte en el sentido de un alojamiento de cables, puede garantizarse una fuerza de retorno dependiente de la solicitation de resorte del almacenamiento de cable a lo largo de la longitud de extraccion completa del cable tensor desde el almacenamiento de cable, concretamente con una trayectoria de la fuerza, que a causa del empleo de un resorte de gas a lo largo de la longitud de extraccion solo se modifica ligeramente en comparacion. Por tanto, se deducen condiciones de arriostramiento ventajosas independientemente del tamano del toldo, porque el almacenamiento de cable puede ajustarse en virtud del guiado de cable tensor que forma bucles entre dos conjuntos de rodillos tensores a pesar de un recorrido de resorte limitado mediante la election de laSince a guided tensioning cable is used on a cable storage and the cable storage is spring pre-tensioned in the direction of a cable housing, a return force dependent on the spring request of the cable storage along the length can be guaranteed. of the complete extraction length of the tensioning cable from the cable storage, specifically with a force path, which due to the use of a gas spring along the extraction length is only slightly modified in comparison. Therefore, advantageous bracing conditions are deduced regardless of the size of the awning, because the cable storage can be adjusted by virtue of the tensioning cable guide that loops between two sets of tension rollers despite a limited spring travel by the choice of the

cantidad de bucles de cable entre los rodillos tensores de una manera facil al tamano respectivo del toldo que va a tensarse.number of cable loops between the tension rollers in an easy manner to the respective size of the awning to be tensioned.
Esto tambien es valido para el empleo del dispositivo tensor para enrollar el toldo. Para enrollar el toldo se fija el cable tensor en un rodillo de enrollamiento conectado mediante accionamiento con el arbol de enrollamiento, que por tanto se solicita con un momento de giro eficaz en el sentido del enrollamiento. Un accionamiento previsto para extender el toldo desde el arbol de enrollamiento, que debe conectarse a un cable de traccion que se engancha al toldo para extender el toldo, debe extender por tanto el toldo en contra del momento de retencion dependiente del almacenamiento de cable, lo que permite el arriostramiento de resorte requerido del toldo sobre el arbol de enrollamiento, concretamente incluso cuando se toma distancia con respecto a un arbol de enrollamiento rlgido y se emplea un arbol de enrollamiento en forma de un cable de traccion tensionado entre extremos de arbol, de modo que tambien pueden arriostrarse ventajosamente toldos con mayores superficies de lona.This is also valid for the use of the tensioning device for winding the awning. In order to wind the awning, the tensioning cable is fixed on a winding roller connected by actuation with the winding shaft, which is therefore requested with an effective turning moment in the direction of winding. A drive intended to extend the awning from the winding shaft, which must be connected to a traction cable that hooks to the awning to extend the awning, must therefore extend the awning against the retention time dependent on the cable storage, which allows the required spring bracing of the awning on the winding shaft, particularly even when a distance is taken from a rigid winding tree and a winding shaft is used in the form of a tensioned tension cable between tree ends, of so that awnings with larger canvas surfaces can also be advantageously braced.
Habitualmente, la construccion de carga para un toldo del tipo descrito comprende al menos dos soportes, en los que se arriostra el toldo. Si se dispone el resorte de gas con el almacenamiento de cable en uno de estos soportes tubulares, entonces se deducen condiciones de construccion especialmente sencillas, porque no tienen que alojarse de manera separada ni el resorte de gas ni el almacenamiento de cable. Dado que el cable tensor se engancha en el rodillo de enrollamiento, que debe conectarse con el arbol de enrollamiento de manera resistente al giro, puede alojar el soporte tubular, en su extremo superior, el rodillo de enrollamiento, cuyo arbol perpendicular al eje de soporte atraviesa el soporte tubular o un soporte de cojinete para el rodillo de enrollamiento y esta conectado mediante accionamiento con el arbol de enrollamiento.Usually, the load construction for a canopy of the type described comprises at least two supports, in which the awning is braced. If the gas spring with the cable storage is arranged in one of these tubular supports, then especially simple construction conditions are deduced, because neither the gas spring nor the cable storage have to be accommodated separately. Since the tensioning cable is hooked on the winding roller, which must be connected to the winding shaft in a rotatable manner, it can accommodate the tubular support, at its upper end, the winding roller, whose shaft perpendicular to the support axis it passes through the tubular support or a bearing support for the winding roller and is connected by drive with the winding shaft.

Modo de ejecucion de la presente invencionMode of execution of the present invention
El dispositivo tensor segun las figuras 1 y 2 presenta un almacenamiento 1 de cable, que comprende dos conjuntos 2, 3 de rodillos tensores. Mientras el conjunto 2 de rodillos tensores esta montado de manera fija en un soporte 4 tubular, el conjunto 3 de rodillos tensores esta dispuesto de manera desplazable axialmente sobre una placa 5 de cabeza en el soporte 4 tubular, concretamente sobre la biela 6 de embolo de un resorte 7 de gas, que esta articulada de manera fija en la zona del conjunto 2 de rodillos tensores. A este respecto, se alcanza la disposicion de modo que tanto el conjunto 2 de rodillos tensores como el eje 8 de articulacion del resorte 7 de gas estan retenidos en un inserto 9 de cojinete del soporte 4 tubular. El cable 10 tensor fijado a la placa 5 de cabeza se gula en vaiven formando bucles entre los dos conjuntos 2 y 3 de rodillos tensores, guiandose el cabo 11 de cable tensor que se desvla del almacenamiento 1 de cable hacia fuera a traves de un rodillo 12 de desviacion radialmente con respecto al soporte 4.The tensioning device according to figures 1 and 2 has a cable storage 1, comprising two sets 2, 3 of tension rollers. While the assembly 2 of tension rollers is fixedly mounted on a tubular support 4, the assembly 3 of tension rollers is arranged axially movable on a head plate 5 in the tubular support 4, specifically on the connecting rod connecting rod 6 a gas spring 7, which is fixedly articulated in the area of the tension roller assembly 2. In this regard, the arrangement is reached so that both the tensioning roller assembly 2 and the articulation axis 8 of the gas spring 7 are retained in a bearing insert 9 of the tubular support 4. The tensioning cable 10 fixed to the head plate 5 is guided in vaiven by forming loops between the two sets 2 and 3 of tension rollers, the tensioning cable end 11 being guided away from the cable storage 1 outwards through a roller 12 deflection radially with respect to the support 4.
En la figura 4 se representa esquematicamente un toldo 13 no segun la invencion, que se fija a lo largo de una llnea 14 de separacion o de plegado en un arbol 15 de enrollamiento, que esta retenido entre dos soportes 16, 17 y puede accionarse con ayuda de un motor previsto en el interior del arbol 15 de enrollamiento de una manera conocida por si misma en el sentido del enrollamiento del toldo 13. Los extremos 18 del toldo 13 dirigidos hacia fuera desde el arbol 15 de enrollamiento estan conectados con un cable 19 de traccion que por un lado esta soportado con transferencia de carga a traves de una gula 20 de desviacion en el cabo 11 de cable tensor y por otro lado esta soportado a traves de una gula 21 de desviacion en un soporte 22 opuesto al soporte 4 con respecto al arbol 15 de enrollamiento. Por tanto, si el arbol de enrollamiento se desbloquea mediante el motor de accionamiento asociado, el toldo 13 se extiende y se despliega mediante la fuerza del resorte 7 de gas desde el arbol 15 de enrollamiento, porque el cabo 11 de cable tensor se retrae mediante el movimiento de separacion de los dos conjuntos 2, 3 de rodillos tensores con ayuda del resorte 7 de gas pretensado de manera correspondiente al almacenamiento 1 de cable.In Fig. 4 a canopy 13 is shown schematically not according to the invention, which is fixed along a separation or folding line 14 in a winding shaft 15, which is held between two supports 16, 17 and can be operated with help of a motor provided inside the winding shaft 15 in a manner known per se in the direction of the awning winding 13. The ends 18 of the awning 13 directed outwardly from the winding shaft 15 are connected with a cable 19 of traction which on the one hand is supported with load transfer through a diverting guide 20 in the tension cable end 11 and on the other hand it is supported through a diverting guide 21 in a support 22 opposite the support 4 with with respect to the winding tree 15. Therefore, if the winding shaft is unlocked by the associated drive motor, the awning 13 is extended and deployed by the force of the gas spring 7 from the winding shaft 15, because the tension cable end 11 is retracted by the separation movement of the two sets 2, 3 of tension rollers with the help of the prestressed gas spring 7 corresponding to the cable storage 1.

El toldo 13 no segun la invencion se muestra en la figura 4 en la posicion desplegada. Para enrollar el toldo 13, se activa el motor del arbol 15 de enrollamiento, de modo que el toldo 13 se enrolla en contra de la fuerza tensora del almacenamiento 1 de cable sobre el arbol 14 de enrollamiento. Por tanto, el almacenamiento 1 de cable solicitado por el resorte 7 de gas retiene tensado el toldo 13 en cada posicion de enrollamiento. Si el toldo 13 desplegado por fuerzas externas, por ejemplo por fuerzas de viento o por fuerzas de peso condicionadas por precipitaciones, se carga en una magnitud que sobrepasa la fuerza tensora del almacenamiento 1 de cable, el cabo 11 de cable tensor se extiende de ese modo hacia fuera del almacenamiento 1 de cable, hasta que la carga externa queda por debajo de nuevo de la fuerza tensora del almacenamiento 1 de cable. Esto puede estar condicionado por una disminucion de las fuerzas de viento o por un drenaje del agua de precipitacion que se acumula sobre el toldo 13. Por tanto, con la disminucion de la carga externa, el toldo 13 vuelve a su posicion de salida, en la que la carga externa del toldo 13 y de la construccion con transferencia de carga se limita por la fuerza tensora maxima del almacenamiento 1 de cable.The awning 13 according to the invention is shown in Figure 4 in the deployed position. To wind the awning 13, the motor of the winding shaft 15 is activated, so that the awning 13 is wound against the tensioning force of the cable storage 1 on the winding shaft 14. Therefore, the cable storage 1 requested by the gas spring 7 retains the awning 13 in each winding position. If the awning 13 deployed by external forces, for example by wind forces or by weight forces conditioned by precipitation, is loaded in a magnitude that exceeds the tensile force of the cable storage 1, the tension cable end 11 extends from that mode out of the cable storage 1, until the external load is again below the tensile force of the cable storage 1. This may be conditioned by a decrease in wind forces or by a drainage of the precipitation water that accumulates on the awning 13. Therefore, with the decrease of the external load, the awning 13 returns to its starting position, in that the external load of the awning 13 and the construction with load transfer is limited by the maximum tensile force of the cable storage 1.
Segun la figura 5, segun la invencion, el arbol 15 de enrollamiento esta montado entre el soporte 4 que aloja el almacenamiento 1 de cable y el soporte 22 opuesto, mientras que los soportes 16 y 17 sirven para soportar el cable 19 de traccion que engancha los extremos 18 del toldo 13 a lo largo de las gulas 20, 21 de desviacion. Para la solicitacion del cable 19 de traccion sirve un cable 30 de accionamiento, que puede enrollarse mediante un motor o manualmente en un arbol 23 de enrollamiento y discurre a lo largo de un rodillo 24 de desviacion hacia la gula 20 de desviacion, con la que esta conectado de manera resistente a la traccion.According to Figure 5, according to the invention, the winding shaft 15 is mounted between the support 4 that houses the cable storage 1 and the opposite support 22, while the supports 16 and 17 serve to support the traction cable 19 that engages the ends 18 of the awning 13 along the deflection guides 20, 21. For the request of the traction cable 19, a drive cable 30 is used, which can be wound by a motor or manually in a winding shaft 23 and runs along a deflection roller 24 towards the deflection guide 20, with which It is connected in a tensile way.
El arbol 15 de enrollamiento esta conectado mediante accionamiento con un rodillo 25 de enrollamiento, que esta montado sobre el soporte 4 con el almacenamiento 1 de cable, tal como puede extraerse esto de la figura 3. En este rodillo 25 de enrollamiento se engancha el cabo 11 de cable tensor que discurre desde el almacenamiento 1 de cable, de modo que el rodillo 25 de enrollamiento se carga a traves del cabo 11 de cable tensor mediante el almacenamiento 1 de cable solicitado por resorte en el sentido del desenrollamiento mediante un momento de giro, que actua sin embargo sobre el arbol 15 de enrollamiento en el sentido del enrollamiento del toldo 13, de modo que el toldo 13 a traves de un arbol 15 de enrollamiento solicitado en el sentido del enrollamiento se retiene en la posicion de extension correspondiente, que se determina por el cable 30 de accionamiento enrollado sobre el arbol 23 de enrollamiento. Sin embargo, en este caso esta limitada la liberacion del toldo 13 en el caso de una carga externa por la longitud de extension del enrollamiento de toldo en cada caso que todavla permanece sobre el arbol 15 de enrollamiento.The winding shaft 15 is connected by drive with a winding roller 25, which is mounted on the support 4 with the cable storage 1, as this can be extracted from Figure 3. In this winding roller 25 the rope is engaged. 11 of tensioning cable that runs from the cable storage 1, so that the winding roller 25 is loaded through the tensioning cable end 11 by means of the cable storage 1 requested by the spring in the direction of the unwinding by a turning moment , which, however, acts on the winding shaft 15 in the direction of the winding of the awning 13, so that the awning 13 through a winding tree 15 requested in the direction of the winding is retained in the corresponding extension position, which it is determined by the drive cable 30 wound on the winding shaft 23. However, in this case the release of the awning 13 in the case of an external load is limited by the length of the awning winding extension in each case that still remains on the winding shaft 15.
Para conseguir condiciones de construccion sencillas, el soporte 26 de cojinete se apoya para el rodillo 25 de enrollamiento sobre el extremo superior del soporte 4, atravesando el arbol 27 del rodillo 25 de enrollamiento el soporte 26 de cojinete y estando conectado de manera resistente al giro con el arbol 15 de enrollamiento. Con este fin, el arbol 27 del rodillo 25 de enrollamiento forma una horquilla 28 de alojamiento para un vastago 29 de conexion del arbol 15 de enrollamiento. Sin embargo, el arbol 15 de enrollamiento no debe configurarse como arbol rlgido, sino que tambien puede estar compuesto por medios de traccion tensados entre extremos de arbol de conexion, en los que el toldo 13 esta fijado a lo largo de una llnea 14 de separacion o de plegado, porque se trata unicamente de de enrollar el toldo 13 alrededor de un nucleo, ya sea alrededor de un arbol rlgido o alrededor de medios de traccion tensados.To achieve simple construction conditions, the bearing support 26 is supported for the winding roller 25 on the upper end of the support 4, the shaft 27 of the winding roller 25 traversing the bearing support 26 and being connected in a rotatable manner with the winding tree 15. To this end, the shaft 27 of the winding roller 25 forms a housing fork 28 for a connecting rod 29 of the winding shaft 15. However, the winding shaft 15 should not be configured as a rigid shaft, but may also be made up of tensioned tensioning means between connecting shaft ends, in which the awning 13 is fixed along a separation line 14 or folding, because it is only about winding the awning 13 around a core, either around a rigid tree or around tensioned tensioning means.
