\hbox{persiana.}

The invention relates to a static device for cleaning a sliding shutter installed in a window or door opening, said device comprising an oblong support provided with a cleaning element applicable against said

 \ hbox {blind.}

State of the art

La limpieza manual de una persiana corredera, típicamente una persiana enrollable, es engorrosa y en ocasiones puede ser peligrosa. En efecto, las partes superiores de la persiana suelen ser de difícil acceso y para alcanzar la cara exterior a menudo es necesario subirse a una escalera o a un andamio. Para evitar esta limpieza manual se han propuesto diversos dispositivos que aprovechan el movimiento ascendente y descendente de la persiana para realizar automáticamente una limpieza de la misma. A título de ejemplo, puede citarse la solicitud de modelo de utilidad español número U9103042 que describe una barra provista de un cepillo que se coloca transversalmente en la abertura de una ventana de manera que el cepillo queda en contacto con la persiana en toda su anchura. La barra se fija a las paredes de la abertura de ventana por medio de una placas intermedias. Semejante dispositivo resuelve adecuadamente la limpieza automática de la persiana, pero presenta el inconveniente de que su correcta instalación no es sencilla y es difícilmente adaptable a cualquier anchura de ventana. En esta misma línea, cabe citar la solicitud de modelo de utilidad español número U200002434 en la cual la barra provista de un cepillo se fija a presión en el borde inferior del cajón de la persiana. Este dispositivo, si bien es de fácil instalación, presenta el inconveniente de que no es aplicable a cualquier persiana y por otra parte no puede utilizarse para limpiar la cara interior de una persiana.Manual cleaning of a sliding shutter, typically a roller blind is cumbersome and sometimes It can be dangerous. Indeed, the upper parts of the blinds are usually difficult to reach and to reach the face outside it is often necessary to climb a ladder or a scaffold. To avoid this manual cleaning, several have been proposed devices that take advantage of upward and downward movement of the blind to automatically perform a cleaning of the same. As an example, you can cite the model request for Spanish utility number U9103042 describing a bar provided with a brush that is placed transversely in the opening of a window so that the brush is in contact with the blind in all its width. The bar is fixed to the opening walls of window by means of an intermediate plates. Similar device properly solves the automatic cleaning of the blind, but has the disadvantage that its correct installation is not simple and is hardly adaptable to any window width Along the same lines, the request for Spanish utility model number U200002434 in which the bar provided with a brush is fixed under pressure on the lower edge of the drawer of the blind. This device, although it is easy installation, has the disadvantage that it is not applicable to any blind and on the other hand cannot be used to clean The inside face of a blind.

Se aprecia pues la necesidad de disponer de un dispositivo del tipo indicado anteriormente que sea de fabricación sencilla, fácilmente instalable en todo tipo de aberturas de puerta o de ventana de diferentes anchuras y aplicable tanto a la cara exterior como a la cara interior de las persianas.The need to have a device of the type indicated above that is manufactured simple, easily installable in all types of door openings or window of different widths and applicable to both the face exterior as to the inner face of the blinds.
