Abstract

The invention relates to a support which can hold filters intended to collect the dirt due to the suction of mechanical air extraction vents. This support consists of a rigid base (1) which is self-adhesive on its rear surface, the base being pierced with a round hole (2). On its front surface we will find, on its lateral edges and its bottom edge, guide rails (3) which are used to hold the filter in place, a filter which will have the shape of the rigid base. This support can be fitted on all the types of mechanical extraction vents existing on the international market.

Description

La présente invention concerne un support de filtre de protection contre les salissures dues à l'aspiration, qui s'applique sur les bouches d'extraction de ventillation mécanique des habitats collectifs.The present invention relates to a filter protection support against dirt due to suction, which is applied to the exhaust vents of mechanical ventilation of collective habitats.

Les filtres sont jusqu'a présent dépourvus de support et donc prévus pour être autocollants ou emboitable. Ce qui engendre des problèmes de fabrication et d'encollage, de plus, du fait de la nature absorbante du filtre, lten- collage est hazardeux au niveau du résultat car la colle est absorbé par le filtre, et donc lors de l'utilisation on se trouve face a des problèmes de non collage. Ces problèmes sont à ajouter au fait qu'il existe une multitude de forme de bouche d'extraction de ventillation mécanique, qui necessitent plusieur formes de filtres.The filters are so far devoid of support and therefore intended to be self-adhesive or nestable. This creates manufacturing and sizing problems, moreover, due to the absorbent nature of the filter, lint-bonding is hazardous in terms of the result because the glue is absorbed by the filter, and therefore during use, is faced with problems of non-sticking. These problems are added to the fact that there are a multitude of forms of mechanical ventilation extraction mouth, which require several forms of filters.

Le présent support selon l'invention permet de remédier à tous ces problèmes, il comporte en effet outre le fond rigide(1) autocollant sur sa face arrière, fond percé d'un trou rond(2). Sur sa face avant, nous trouvons sur ses cotés latéraux et son coté bas, des rails de guidage(3), qui servent à maintenir le filtre en place. Du fait de sa forme, le support peut être placé sur tous les types de bouches d'extraction disponibles sur le marché international et evite donc une multitude de forme de filtre par la standardisation de sa forme car en effet le filtre sera de la même dimention que le fond du support.The present support according to the invention makes it possible to remedy all these problems, it in fact comprises, in addition to the rigid bottom (1) which is self-adhesive on its rear face, the bottom pierced with a round hole (2). On its front side, we find on its lateral sides and its low side, guide rails (3), which serve to hold the filter in place. Due to its shape, the support can be placed on all types of extraction vents available on the international market and therefore avoids a multitude of filter forms by standardizing its form because indeed the filter will be of the same size than the bottom of the support.

On peut imaginer que le support puisse avoir, de plus, dans un soucis d'esthétique, toutes sortes de couleurs. One can imagine that the support could have, moreover, in an aesthetic concern, all kinds of colors.

En utilisation pratique, il suffira de retirer la protection sur la partieautocollante au dos du fond rigide(1) puis de présenter la support sur la bouche d'extraction de ventillation mécanique de façon à ce que le centre du trou(2) soit placé sur le centre de la bouche d'extraction puis de coller le support. Il suffira ensuite de glisser le filtre dans les rails de guidage(3) placés sur la face avant du fond rigide(1), et de changer le filtre dés le moment ou il sera sale, ce qui permettra a l'utilisateur d'avoir toujours une bouche d'extraction mécanique propre. In practical use, it will suffice to remove the protection on the adhesive part on the back of the rigid base (1) then present the support on the mechanical ventilation extraction mouth so that the center of the hole (2) is placed on the center of the extraction mouth then glue the support. It will then suffice to slide the filter into the guide rails (3) placed on the front face of the rigid bottom (1), and to change the filter as soon as it becomes dirty, which will allow the user to have always a clean mechanical extraction mouth.

Claims

10 Device for holding the filters intended to avoid soiling of the mechanical ventilation extraction vents of collective dwellings, characterized in that it comprises a rigid bottom (1) pierced with a round hole (2) and comprising on the lateral sides and the bottom side of the front face of the guide rails (3) serving to hold the filter in place, said filter having the shape of a rigid bottom.

20 Device according to claim 1, characterized in that the rigid base (1) is self-adhesive on its rear face.
