Description

EJE DE ENROLLAMIENTO CON TUBO DE ACCIONAMIENTO WINDING AXLE WITH DRIVE TUBE
La presente invención se refiere a un sistema para el enrollado de elementos laminares, que comprende un tubo en cuyo interior se aloja un elemento de accionamiento del movimiento de enrollado del elemento laminar.The present invention relates to a system for winding laminar elements, which comprises a tube inside which houses an element for driving the winding movement of the laminar element.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
En la actualidad es conocida la utilización de sistemas para el enrollado de elementos laminares que comprenden un motor, de manera que el elemento laminar se enrolla y se desenrolla simplemente accionando un pulsador.At present, the use of systems for winding laminar elements comprising a motor is known, so that the laminar element is wound and unwound simply by pressing a button.
Para ello, los sistemas conocidos actualmente comprenden un motor cilindrico que se aloja en el interior de un tubo, alrededor del cual se enrolla el elemento laminar .For this, the currently known systems comprise a cylindrical motor that is housed inside a tube, around which the laminar element is wound.
Ejemplos de estos sistemas se describen en los documentos WO 2008/110334 y DE 20219780 Ul. El inconveniente principal de estos sistemas es que es necesario dejar un espacio entre el extremo del tubo y la superficie donde se fija, por ejemplo una pared. De esta manera, si se colocan dos elementos laminares una junto a la otra siempre existirá una separación entre las mismas. Este espacio es debido a que los medios de transmisión del movimiento entre el motor y el tubo están formados en un cabezal colocado en el exterior del tubo.Examples of these systems are described in WO 2008/110334 and DE 20219780 Ul. The main drawback of these systems is that it is necessary to leave a space between the end of the tube and the surface where it is fixed, for example a wall. In this way, if two laminar elements are placed next to each other there will always be a separation between them. This space is due to the fact that the means of transmission of the movement between the engine and the tube are formed in a head placed outside the tube.
Además, en el hecho de la presencia de este cabezal para transmitir el movimiento obliga a colocar necesariamente el motor próximo a uno de los extremos del tubo, lo que dificulta el equilibrado del conjunto del tubo y el motor.In addition, due to the presence of this head to transmit the movement, it is necessary to place the motor near one of the ends of the tube, which makes it difficult to balance the tube and motor assembly.
Por lo tanto, resulta evidente la necesidad de un sistema para el enrollado de elementos laminares que permita que todos sus componentes estén alojados en el interior del tubo, no dejando ningún espacio o separación cuando se colocan dos elementos laminares una junto a la otra o cuando se fijan a una superficie tal como una pared. Además, otro objetivo del sistema de la presente invención es permitir que el motor se coloque en cualquier posición en el interior del tubo, por ejemplo en una posición centrada, que facilite el equilibrado del conjunto del tubo y el motor.Therefore, it is evident the need for a system for winding laminar elements that allows all its components to be housed in the inside the tube, leaving no space or separation when two laminar elements are placed next to each other or when they are fixed to a surface such as a wall. In addition, another objective of the system of the present invention is to allow the motor to be placed in any position inside the tube, for example in a centered position, which facilitates the balancing of the tube and motor assembly.

DESCRIPCIÓN DE UNA REALIZACIÓN PREFERIDADESCRIPTION OF A PREFERRED EMBODIMENT
Tal como se puede apreciar en las figuras, el sistema para el enrollado de elementos laminares de la presente invención comprende un tubo 1 en el interior del cual se aloja un motor 2. Dicho motor 2 es un motor convencional del tipo actualmente conocido para su uso en el accionamiento del enrollado y desenrollado de elementos laminares. Debe indicarse que aunque en la realización representada el accionamiento de la rotación se realiza mediante un motor, este movimiento de rotación se podria accionar mediante un elemento de accionamiento no motorizado .As can be seen in the figures, the system for winding laminar elements of the present invention comprises a tube 1 inside which a motor 2 is housed. Said motor 2 is a motor conventional of the type currently known for use in the drive of winding and unwinding of laminar elements. It should be noted that although in the embodiment shown the rotation drive is performed by a motor, this rotation movement could be driven by a non-motorized drive element.
Sobre dicho tubo 1 se enrolla el elemento laminar (no representado) cuando se acciona dicho motor 2 cuando el elemento laminar está en la posición desplegada.On said tube 1 the laminar element (not shown) is wound when said motor 2 is driven when the laminar element is in the deployed position.
En la presente invención descripción se entiende como "elemento laminar" cuando elemento susceptible de enrollarse sobre un tubo, por ejemplo una cortina, un tejido, un tejido no tejido, una persiana u otros. El movimiento entre el eje de salida del motor 2 y el tubo 1 se transmite mediante una corona interna 3 solidaria en rotación con el eje de salida del motor 2, la cual también es solidaria en rotación con una corona externa 4. A su vez, esta corona externa 4 es solidaria en rotación con el tubo 1. Para ello, el tubo 1 comprende en su interior una pluralidad de ranuras longitudinales, en cuyo interior se alojan los dientes de dicha corona externa 4. En la realización representada, el tubo 1 también comprende en sus extremos unos soportes 5 en forma de placas que también están alojados en el interior del tubo 1. Estos soportes 5 se fijan a una superficie, tal como una pared, mediante cualquier medio de fijación adecuado, por ejemplo tornillos. A través de uno de dichos soportes 5 pasa el cable de alimentación del motor 2.In the present invention description is understood as "laminar element" when element capable of being wound on a tube, for example a curtain, a fabric, a non-woven fabric, a blind or others. The movement between the output shaft of the motor 2 and the tube 1 is transmitted by means of an internal crown 3 in rotation with the output shaft of the motor 2, which is also integral in rotation with an external crown 4. In turn, this external crown 4 is integral with rotation with the tube 1. For this, the tube 1 comprises in its interior a plurality of longitudinal grooves, in which the teeth of said external crown 4 are housed. In the embodiment shown, the tube 1 It also comprises at its ends some supports 5 in the form of plates that are also housed inside the tube 1. These supports 5 are fixed to a surface, such as a wall, by any suitable fixing means, for example screws. The power cable of motor 2 passes through one of said supports 5.
Debe indicarse, sin embargo, que no es necesario que estén presentes dos soportes 5 en el tubo 1, sino que podria haber únicamente un soporte 5, cerrando el otro extremo del tubo mediante cualquier elemento adecuado. Para permitir el equilibrado de todo el conjunto, el sistema de la presente invención también comprende una o dos varillas 6, dos en el caso de la realización representada, que se extienden desde los extremos del motor 2 hasta los soportes 5. El equilibrado del conjunto se consigue mediante una pluralidad de discos de compensación 7, que se pueden colocar sobre dichas varillas 1 y/o sobre dicho motor 2.It should be noted, however, that it is not necessary that two supports 5 be present in the tube 1, but that there could be only one support 5, closing the other end of the tube by any suitable element. To allow balancing of the entire assembly, the system of the present invention also comprises one or two rods 6, two in the case of the embodiment shown, extending from the ends of the motor 2 to the supports 5. The balancing of the assembly it is achieved by a plurality of compensation discs 7, which can be placed on said rods 1 and / or on said motor 2.
Cuando el elemento laminar está colocado en la posición desplegada, para enrollarla sobre el tubo 1 simplemente es necesario accionar el motor 2 mediante un pulsador o mando a distancia externo (no representado) , de manera que se acciona la rotación del eje de salida del motor 2 en un sentido. La rotación del eje de salida del motor 2 se transmite al tubo 1, tal como se ha indicado anteriormente, mediante la corona interna 3 y la corona externa 4, de manera que la rotación del tubo 1 alrededor de su eje longitudinal en un sentido provoca el enrollado del elemento laminar sobre el mismo.When the laminar element is placed in the unfolded position, to wind it over the tube 1 it is simply necessary to operate the motor 2 by means of an external push button or remote control (not shown), so that the rotation of the motor output shaft is actuated 2 in a sense. The rotation of the output shaft of the motor 2 is transmitted to the tube 1, as indicated above, by the internal crown 3 and the external crown 4, so that the rotation of the tube 1 around its longitudinal axis in one direction causes the winding of the laminar element on it.
Para desenrollar el elemento laminar simplemente es debe accionar la rotación del eje de salida del motor 2 en el sentido contrario, lo que provocará la rotación en el sentido contrario del tubo 1 mediante dichas coronas interna 3 y externa 4.To unwind the laminar element, simply rotate the output shaft of the motor 2 in the opposite direction, which will cause the rotation in the opposite direction of the tube 1 by means of said internal 3 and external 4 crowns.
Tal como se ha indicado anteriormente, como todos los componentes del sistema de la presente invención están alojados en el interior del tubo 1, no se deja ninguna separación entre el tubo 1 y cualquier elemento adyacente, sea el tubo 1 de un elemento laminar o una pared.As indicated above, since all the components of the system of the present invention are housed inside the tube 1, no separation is left between the tube 1 and any adjacent element, be it the tube 1 of a laminar element or a wall.
A pesar de que se ha hecho referencia a una realización concreta de la invención, es evidente para un experto en la materia que el sistema de enrollado descrito es susceptible de numerosas variaciones y modificaciones, y que todos los detalles mencionados pueden ser substituidos por otros técnicamente equivalentes, sin apartarse del ámbito de protección definido por las reivindicaciones adjuntas . Although reference has been made to a specific embodiment of the invention, it is apparent to one skilled in the art that the described winding system is susceptible to numerous variations and modifications, and that all the mentioned details can be replaced by other technically equivalent ones, without departing from the scope of protection defined by the appended claims.
