Description

La présente invention a trait à une grille d'aérage et, en particulier, à une grille d'aérage appliquée en combinaison avec des portes, fenêtres ou éléments similaires et cela surtout avec le bord supérieur de ces derniers.The present invention relates to a ventilation grille and, in particular, to a ventilation grille applied in combination with doors, windows or similar elements and this especially with the upper edge of the latter.

On connaît jusqu'à présent deux types de grilles d'aérage, à savoir un premier type, dont la grille peut coulisser longitudinalement et les passages de la partie coulissante peuvent être décalés par rapport à des passages correspondants d'une partie fixe de la grille pour fermer les ouvertures d'aérage ou les ouvrir partiellement ou totalement, et un deuxième type, dont les ouvertures d'aérage sont prévues dans un élément rotatif comportant essentiellement un tambour muni de fentes longitudinales, diamétralement opposées, dont la superposition verticale ou la juxtaposition horizontale permet ou empêche l'aérage par passage d'air entre les deux cô- tés de la grille d'aérage.Up to now, two types of ventilation grilles are known, namely a first type, the grid of which can slide longitudinally and the passages of the sliding part can be offset with respect to corresponding passages of a fixed part of the grid. to close the ventilation openings or to open them partially or completely, and a second type, the ventilation openings of which are provided in a rotary element essentially comprising a drum provided with diametrically opposed longitudinal slots, the vertical superposition or juxtaposition horizontal allows or prevents aeration by passing air between the two co - sides of the ventilation grid.

Tandis que le premier de ces deux types de grilles d'aérage connus laisse beaucoup à désirer au point de vue étanchéité, le deuxième type, bien que répondant à toutes les exigences d'efficacité, d'étanchéité, etc., présente l'inconvénient d'être relativement cher.While the first of these two types of known ventilation grilles leaves much to be desired from the point of view of sealing, the second type, although meeting all the requirements for efficiency, sealing, etc., has the drawback to be relatively expensive.

Or, la présente invention a pour objet la réalisation d'une grille d'aérage se distinguant des types de grilles d'aérage connus susmentionnés en ce qu'elle réunit tous les avantages des types connus jusqu'à présent, à savoir, d'une part, la simplicité et le prix avantageux du premier type et, d'autre part, l'efficacité et l'étanchéité du deuxième type, et présentant en outre l'avantage de se prêter à deux modes d'exécution, respectivement à isolation thermique et sans isolation thermique.However, the subject of the present invention is the production of a ventilation grille which differs from the types of known ventilation grilles mentioned above in that it combines all the advantages of the types known up to now, namely, on the one hand, the simplicity and the advantageous price of the first type and, on the other hand, the efficiency and tightness of the second type, and also having the advantage of being suitable for two embodiments, respectively with thermal insulation and without insulation thermal.

La grille d'aérage selon l'invention se compose essentiellement d'un profilé creux présentant de part et d'autre une fente ou une rangée de fentes, ainsi que d'au moins un élément coulissant monté dans le profilé creux à l'un de ses côtés muni d'une ou de plusieurs fentes, et susceptible d'être déplacé transversalement par rapport à son axe longitudinal pour fermer ou ouvrir ladite fente ou ouverture ou rangée de fentes ou d'ouvertures.The ventilation grille according to the invention essentially consists of a hollow profile having on either side a slot or a row of slots, as well as at least one sliding element mounted in the hollow profile at one its sides provided with one or more slots, and capable of being moved transversely relative to its longitudinal axis to close or open said slot or opening or row of slots or openings.

Les caractéristiques et avantages de l'invention ressortiront plus clairement de la description détaillée suivante de deux exemples d'exécution de la grille d'aérage concernée, donnée sans la moindre intention restrictive avec référence, au dessin annexé, où

  • la figure 1 représente de manière schématique une vue de face d'une grille d'aérage selon l'invention;
  • la figure 2 représente à plus grande échelle une coupe de la grille d'aérage selon la figure 1, pratiquée suivant la ligne II-II de cette dernière; et
  • la figure 3 représente une vue analogue à celle de la figure 1, mais d'une grille d'aérage à isolation thermique.
The characteristics and advantages of the invention will emerge more clearly from the following detailed description of two exemplary embodiments of the ventilation grille concerned, given without any restrictive intention with reference, to the attached drawing, where
  • Figure 1 schematically shows a front view of a ventilation grille according to the invention;
  • Figure 2 shows on a larger scale a section of the ventilation grid according to Figure 1, taken along line II-II thereof; and
  • FIG. 3 represents a view similar to that of FIG. 1, but of a thermally insulated ventilation grid.

Comme on le voit en se reportant aux figures 1 et 2, la grille d'aérage selon le présent mode d'exécution de l'invention se compose essentiellement de deux profilés longitudinaux 1 et 2, dont le premier profilé est appliqué par exemple au bord supérieur d'une baie de porte, d'une baie de fenêtre ou autre, et le deuxième profilé (profilé inférieur) sert de lisse supérieure du châssis de porte ou de fenêtre ou de tout autre élément concerné.As can be seen with reference to FIGS. 1 and 2, the ventilation grid according to the present embodiment of the invention essentially consists of two longitudinal sections 1 and 2, the first section of which is applied for example to the edge upper of a door opening, a window opening or the like, and the second profile (lower profile) serves as the top rail of the door or window frame or of any other element concerned.

Les susdits profilés 1 et 2 sont, selon le système de l'invention, conçus de manière que dans l'espace 3, formé par leurs creux, peut être logé un élément coulissant 4, se présentant, en l'ocurrence, sous forme d'un parallélipipède creux, dont chacune des deux extrémités est articulée, par exemple au moyen d'un axe de pivotement, respectivement 5 et 6, à un levier, respectivement 7 et 8, dont l'autre extrémité est connectée par un axe d'articulation, respectivement 9 et 10, au susdit profilé 1, un de ces leviers, en l'occurrence le levier 8, étant muni d'une poignée 11 située à l'extérieur du profilé 1 et susceptible d'être commandée pour mettre ledit élément coulissant 4 en une position supérieure ou inférieure.The above profiles 1 and 2 are, according to the system of the invention, designed so that in the space 3, formed by their recesses, can be accommodated a sliding element 4, being, in this case, in the form of 'a hollow parallelipiped, each of whose two ends is articulated, for example by means of a pivot axis, respectively 5 and 6, to a lever, respectively 7 and 8, the other end of which is connected by an axis of articulation, respectively 9 and 10, in the above profile 1, one of these levers, in this case the lever 8, being provided with a handle 11 located outside of the profile 1 and capable of being controlled to put said element sliding 4 in a higher or lower position.

Pendant ce déplacement, ledit élément coulissant 4 coopère avec des éléments d'étanchéité se présentant par exemple sous forme de brosses 12 et 13 servant à éviter, dans la position dessinée en trait continu dans la figure 2, tout passage d'air d'un côté de la construction vers l'autre et de ce fait la pénétration de poussière, d'insectes, etc.During this movement, said sliding element 4 cooperates with sealing elements appearing, for example, in the form of brushes 12 and 13 serving to avoid, in the position drawn in solid lines in FIG. 2, any passage of air from a side of the building towards the other and thereby the penetration of dust, insects, etc.

Pour éviter la pénétration d'insectes d'un côté de la construction vers l'autre lorsque ledit élément coulissant 4 se trouve en position ouverte, dessinée en pointillé dans la figure 2, est prévu entre les profilés 1 et 2 un élément de gaze 14 totalement soustrait à la vue.To prevent the penetration of insects from one side of the construction towards the other when said sliding element 4 is in the open position, drawn in dotted lines in FIG. 2, a gauze element 14 is provided between the profiles 1 and 2. completely hidden from view.

La figure 3 représente un mode d'exécution d'une grille d'aérage selon l'invention à isolation thermique, composée, en l'occurrence, de quatre profilés 15, 16, 17 et 18, séparés deux à deux par des éléments d'isolation, respectivement 19 et 20, de manière à former pour ainsi dire les profilés 1 et 2, l'élément coulissant étant ici également formé par deux profilés 20 et 21, reliés par une bande de matière isolante 22. Dans ce cas, l'élément d'aérage est, de manière non obligatoire, soutenu de manière étanche par quatre éléments appropriés, tels que des brosses, respectivement 23-24 et 25-26.FIG. 3 represents an embodiment of a ventilation grille according to the invention with thermal insulation, composed, in this case, of four sections 15, 16, 17 and 18, separated in pairs by elements d insulation, respectively 19 and 20, so as to form, so to speak, the profiles 1 and 2, the sliding element also being here formed by two profiles 20 and 21, connected by a strip of insulating material 22. In this case, the the ventilation element is, in a non-compulsory manner, supported in leaktight manner by four suitable elements, such as brushes, respectively 23-24 and 25-26.

La grille d'aérage 4 pourra, dans ce cas, également être déplacée vers le haut ou vers le bas au moyen d'un mécanisme 5-11.The ventilation grille 4 may, in this case, also be de placed up or down by a mechanism 5-11.

Il va sans dire que l'invention ne se limite pas aux modes d'exécution décrits dans les lignes précédentes et illustrés par les figures annexées, mais en prévoit toutes sortes de modifications, d'additions et d'adaptations concernant la forme et les dimensions des parties intégrantes de la grille d'aérage concernée, évidemment soumises à la condition de ne pas dépasser son cadre.It goes without saying that the invention is not limited to the embodiments described in the preceding lines and illustrated by the appended figures, but provides for all kinds of modifications, additions and adaptations thereof concerning the shape and the dimensions. integral parts of the ventilation grid concerned, obviously subject to the condition of not exceeding its frame.

C'est ainsi, par exemple, que les déplacements vers le haut et vers le bas de l'élément coulissant pourront être commandés de toute manière appropiée et que les brosses d'étanchéité pourront être montées sur l'élément coulissant 4 tout en garantissant le même résultat.Thus, for example, the upward and downward movements of the sliding element can be controlled in any suitable manner and that the sealing brushes can be mounted on the sliding element 4 while ensuring the same result.

Suivant un mode d'exécution spécial de l'invention, ledit élément coulissant de la grille d'aérage se compose d'une partie supérieure et d'une partie inférieure, qui, dans la position fermée de la grille, s'appliquent étroitement, de manière parfaitement étanche, l'une à l'autre et sont munies de moyens de commande appropriés pour les déplacer séparément ou ensemble, toujours en direction transversale en vue de l'ouverture ou de la fermeture de la grille.According to a special embodiment of the invention, said sliding element of the ventilation grille consists of an upper part and a lower part, which, in the closed position of the grille, are applied closely, perfectly sealed, to each other and are provided with suitable control means for moving them separately or together, always in a transverse direction with a view to opening or closing the grid.
