Description

Fenêtre à gueule de loup possédant un élément mobile de réglage etWolf mouth window having a movable adjusting member and

présentant une étanchéité optimale à l'air et à l'eau. with optimum air and water tightness.

Secteur technique de l'invention : La présente invention concerne le secteur technique des fenêtres et plus précisément celui des fenêtres à gueule de loup . TECHNICAL FIELD OF THE INVENTION The present invention relates to the technical sector of windows and more specifically to that of windows with a wolf's mouth.

Le vocable fenêtre à gueule de loup se dit d'une fenêtre qui se ferme par emboîtement d'un vantail ou ouvrant présentant une gorge ( gueule de loup ) qui reçoit la tranche arrondie du vantail ou ouvrant opposé (appelé mouton ). Les fenêtres à gueule de loup sont désignées également par les termes fermetures à la française . The term wolfmouth window is said to be a window that closes by interlocking a leaf or opening with a throat (mouth of a wolf) that receives the rounded edge of the leaf or opposite leaf (called sheep). Wolfmouth windows are also referred to as French closures.

Art antérieur : On connaît des fenêtres utilisant le système gueule de loup depuis le 18ème siècle. C'est un système d'ouverture et de fermeture traditionnel qui est généralement utilisé dans la plupart des bâtiments anciens. Ce système (et ses différentes variantes que l'on trouve en fonction des régions) fut de moins en moins utilisé dans les constructions récentes, car ce système possédait des inconvénients. PRIOR ART: Windows have been known to have been using the "hangover" system since the 18th century. It is a traditional opening and closing system that is generally used in most old buildings. This system (and its different variants found according to the regions) was less and less used in recent constructions, because this system had disadvantages.

En effet, les gueules de loup possèdent une bonne isolation à l'eau, mais l'étanchéité à l'air n'est pas optimale. Dans les fenêtres à gueule de loup classiques, l'étanchéité à l'air est assurée par simple contact entre les deux vantaux ou ouvrants. Afin de palier ce problème, l'une des solution est l'apport d'une pièce périphérique faisant office de joint. Le joint peut être soit métallique (fixé à la feuillure) soit adhésif en mousse élastomère ou en polypropylène. Mais cette solution ne fournit pas un confort total. En effet, les joints adhésifs sont faciles à poser mais sont peu durables et peu efficaces d'un point de vue acoustique ; les joints métalliques sont durables et efficaces mais exigent un savoir faire pour la pose. De plus, tous ces joints dégradent la qualité esthétique de la fenêtre, en rajoutant une pièce qui n'est pas naturelle à la fenêtre. De nos jours, pour rénover ces fenêtres anciennes, on préfère remplacer lesdites fenêtres à gueule de loup par des fenêtres modernes, afin d'éviter les inconvénients mentionnés précédemment, quitte à dénaturer l'ensemble. Un autre problème majeur est que l'ajustage de la fenêtre à gueule de loup est, certes, réalisé facilement à l'atelier, mais qu'une fois la fenêtre posée et en condition d'utilisation (en fonction par exemple de l'hygrométrie, des couches de peinture successives, etc Indeed, the mouths of wolf have a good insulation with water, but the airtightness is not optimal. In conventional wolf windows, the airtightness is ensured by simple contact between the two leaves or opening. In order to overcome this problem, one of the solutions is the provision of a peripheral piece acting as a seal. The seal may be either metal (attached to the rabbet) or adhesive elastomeric foam or polypropylene. But this solution does not provide total comfort. Indeed, the adhesive joints are easy to install but are unsustainable and acoustically inefficient; metal seals are durable and effective but require a know-how for laying. In addition, all these joints degrade the aesthetic quality of the window, adding a room that is not natural to the window. Nowadays, to renovate these old windows, it is preferred to replace the said window hangover by modern windows, to avoid the disadvantages mentioned above, even to denature the whole. Another major problem is that the adjustment of the window mouth wolf is certainly achieved easily in the workshop, but that once the window and placed in use condition (depending for example hygrometry , successive layers of paint, etc.

.) l'espace entre les deux ouvrants de la fenêtre peut être plus ou moins grand, entraînant soit un blocage de la fenêtre (c'est-à-dire difficulté de manoeuvre), soit un trop grand jeu entre les deux ouvrants, ne permettant pas de créer une étanchéité optimale...DTD: Problème technique posé :. Au regard de tous les inconvénients mentionnés précédemment, il est nécessaire de proposer une fenêtre possédant des caractéristiques esthétiques anciennes (notamment, pour les bâtiments anciens), mais présentant également des performances acoustiques et thermiques que l'on trouve dans les fenêtres modernes. .) the space between the two openings of the window may be larger or smaller, causing either a blockage of the window (that is to say, difficulty of maneuver), or too much clearance between the two openings, not not allowing to create an optimal waterproofness ... DTD: Technical problem posed:. In view of all the drawbacks mentioned above, it is necessary to provide a window with old aesthetic characteristics (especially for old buildings), but also having acoustic and thermal performance found in modern windows.

Résumé de l'invention : La présente invention repose sur une opération originale qui consiste en un réglage d'une fenêtre à gueule de loup présentant des performances acoustiques et thermiques modernes , et possédant des caractéristiques esthétiques anciennes. Celles-ci doivent être obtenues par un réglage de la fenêtre ne dégradant pas sa finition et ne nécessitant pas une intervention lourde. Ce réglage est destiné à l'amélioration de l'étanchéité thermique et acoustique. SUMMARY OF THE INVENTION: The present invention is based on an original operation which consists of an adjustment of a wolfmouth window having modern acoustic and thermal performances, and having old aesthetic characteristics. These must be obtained by adjusting the window does not degrade its finish and does not require heavy intervention. This adjustment is intended to improve the thermal and acoustic sealing.

Description détaillée de l'invention : La présente invention concerne donc une fenêtre (1) à gueule de loup présentant des performances acoustiques et thermiques modernes , et possédant des caractéristiques esthétiques anciennes . 3 La figure 1 représente une vue en coupe horizontale de la fenêtre à gueule de loup selon la présente invention. La figure 2 est une vue en perspective du troisième élément tel que fixé à son vantail ou ouvrant. DETAILED DESCRIPTION OF THE INVENTION The present invention thus relates to a wolf-faced window (1) having modern acoustic and thermal performances, and having old aesthetic characteristics. Fig. 1 shows a horizontal sectional view of the wolf-mouth window according to the present invention. Figure 2 is a perspective view of the third element as attached to its leaf or opening.

La figure 3 est une vue en perspective des deux vantaux ou ouvrants de la fenêtre selon la présente invention. La figure 4 est une représentation de la vis de réglage. La fenêtre à gueule de loup (1) selon la présente invention possède, en plus des deux éléments classiques de ce type de fenêtre, c'est-à-dire en plus des deux vantaux ou ouvrants (2, 3), un troisième élément (4) portant la gueule de loup proprement dite c'est-à-dire la gorge, et ledit élément (4) est mobile en translation latérale sur environ 4 - 5 millimètres par rapport à l'ouvrant (3) sur lequel ce troisième élément est fixé. Cette mobilité permet de faire varier l'espace existant entre lesdits deux vantaux ou ouvrants. Ledit troisième élément (4) est rendu mobile par au moins deux vis de réglage (5), de préférence deux, qui relient ledit troisième élément (4) audit ouvrant correspondant (3). Lesdites deux vis sont séparées l'une de l'autre au maximum de 500 mm et sont placées sur l'axe vertical de la gueule de loup , ceci afin d'apporter une rigidité suffisante de l'ensemble ouvrant (3) + troisième élément (4) . Ledit élément mobile (4) possède au moins une, de préférence deux, protubérances internes (9) et deux protubérances externes (9"). Lesdites protubérances (9) s'encastrent dans des formes ou logements correspondants (10) (fentes adaptées à la largeur desdites protubérances) ménagés dans la partie de l'ouvrant (3) sur laquelle sera fixée cet élément mobile (4) ; tandis que les protubérances (9") encadrent les faces latérales (A et B) de l'ouvrant 3. Figure 3 is a perspective view of the two leaves or openings of the window according to the present invention. Figure 4 is a representation of the adjusting screw. The wolf window (1) according to the present invention has, in addition to the two conventional elements of this type of window, that is to say in addition to the two leaves or opening (2, 3), a third element (4) bearing the mouth of the wolf itself that is to say the throat, and said element (4) is movable in lateral translation about 4 - 5 millimeters relative to the opening (3) on which this third element is fixed. This mobility makes it possible to vary the space existing between said two leaves or doors. Said third element (4) is made mobile by at least two adjusting screws (5), preferably two, which connect said third element (4) to said corresponding opening (3). Said two screws are separated from each other by a maximum of 500 mm and are placed on the vertical axis of the mouth of the wolf, in order to provide sufficient rigidity of the opening assembly (3) + third element (4). Said movable element (4) has at least one, preferably two, internal protuberances (9) and two external protuberances (9 "). Said protrusions (9) fit into corresponding shapes or housings (10) (slots adapted to the width of said protuberances) formed in the part of the opening (3) on which this movable element (4) will be fixed, while the protuberances (9 ") surround the lateral faces (A and B) of the opening 3.

Ledit élément mobile (4) possède, de préférence, les dimensions suivantes : 83 mm en largeur et 55 mm en longueur. Bien sûr, cette élément mobile peut comporter d'autres dimensions en fonction des utilisations souhaitées (par exemple des dimensions adaptées au portes- fenêtres, à des fenêtres très larges, etc ). Ladite vis ou de préférence les deux vis (5) (afin de posséder de bonnes caractéristiques de solidité) ne doivent pas excéder 70 mm en longueur. Cette vis possède deux filetages différents : un filetage proche de la tête (6) , qui est un filetage perpendiculaire à la vis, puis un second filetage (7) classique en forme hélicoïdale autour de la vis. Les deux filetages étant séparés par une zone lisse (8). Ce double filetage permet d'assurer que la vis, une fois rentrée dans le bois, ne puisse plus être retirée (filetage supérieur). Le filetage inférieur (7), permet de régler la position de l'élément mobile par rapport à l'ouvrant correspondant. Avant d'insérer la vis (5), on effectue un avant-trou à l'endroit où doit être placée ladite vis, afin d'éviter une éventuelle casse de ladite vis. Par ce mode d'insertion, on obtient une bonne prise de la vis dans le montant gueule de loup (3) et on évite que la vis ne s'arrache lors des réglages. En fonctionnement, pour faire bouger l'élément mobile, on vis ou on dévisse lesdites vis. La vis (5) est placée à fleur de surface de la gorge ou gueule de loup, et on a donc accès audites vis seulement lorsque la fenêtre est en position ouverte. Au moins un joint de type bande d'étanchéité (11) est placé dans un espace entre ledit élément mobile (4) et la partie correspondante de l'ouvrant (3), (c'est-à-dire espace entre le logement (10) et la protubérance 9). Ce joint (11) possède les qualités de pouvoir aussi bien se détendre25 que se comprimer en fonction des forces qui lui sont appliquées. Ce joint (11) permet donc de garantir une parfaite étanchéité entre l'élément mobile (4) et la partie correspondante (3), puisqu'il épousera le mouvement de l'élément mobile souhaité. De plus, ce joint possède un très bon effet mémoire qui garanti sa bonne utilisation dans le temps . Il est possible de remplacer ce joint d'étanchéité (11) par tout élément de type mousse de polyuréthane, ou élastomère, accessible à l'homme du métier, suffisamment extensible pour remplir les conditions d'étanchéité citées précédemment. D'autres joints (ou dispositifs similaires) (12) peuvent être placés au niveau de la gueule de loup , et/ou du mouton , ici encore afin d'assurer une étanchéité maximale. 15 L'élément mobile (4) afin d'assurer une étanchéité parfaite dépasse également de 4 - 5 mm (correspondant à la longueur de déplacement dudit troisième élément), de part et d'autre dudit ouvrant (3) portant ledit élément mobile. 20 Pour assurer le verrouillage de la fenêtre on utilisera, de préférence, une crémone, tige verticale actionnée par une poignée et qui pénètre en haut et en bas du dormant (cadre de la fenêtre) ; ce dispositif de fermeture est un procédé traditionnel bien connu de l'homme du métier. Said movable element (4) preferably has the following dimensions: 83 mm in width and 55 mm in length. Of course, this movable element may have other dimensions depending on the desired uses (for example dimensions adapted to the French windows, very wide windows, etc.). Said screw or preferably the two screws (5) (in order to have good characteristics of solidity) must not exceed 70 mm in length. This screw has two different threads: a thread near the head (6), which is a thread perpendicular to the screw, and a second thread (7) conventional helical shape around the screw. The two threads being separated by a smooth zone (8). This double thread ensures that the screw, once entered into the wood, can not be removed (upper thread). The lower thread (7) allows to adjust the position of the movable element relative to the corresponding opening. Before inserting the screw (5), a pilot hole is made at the place where said screw is to be placed, in order to avoid any breakage of said screw. By this mode of insertion, we obtain a good grip of the screw in the amount mouth of wolf (3) and we avoid that the screw does not tear during adjustments. In operation, to move the movable element, screws are screwed or unscrewed. The screw (5) is placed flush with the surface of the throat or the mouth of a wolf, and we therefore have access to the screws only when the window is in the open position. At least one seal-type seal (11) is placed in a space between said movable member (4) and the corresponding portion of the opening (3), (i.e. space between the housing ( 10) and the protuberance 9). This seal (11) possesses the qualities of being able to both relax and compress according to the forces applied to it. This seal (11) therefore ensures a perfect seal between the movable member (4) and the corresponding portion (3), since it will match the movement of the desired movable member. In addition, this seal has a very good memory effect that ensures its good use over time. It is possible to replace this seal (11) by any element of polyurethane foam type, or elastomer, accessible to those skilled in the art, sufficiently extensible to fulfill the sealing conditions mentioned above. Other seals (or similar devices) (12) can be placed at the mouth of the wolf, and / or the sheep, again to ensure a maximum seal. The movable element (4) to ensure perfect sealing also exceeds 4 - 5 mm (corresponding to the displacement length of said third element), on either side of said opening (3) carrying said movable element. To ensure the locking of the window is preferably used a cremone, vertical rod actuated by a handle and which penetrates up and down the frame (window frame); this closure device is a traditional method well known to those skilled in the art.

Procédé de réglage d'une fenêtre à gueule de loup selon la présente 25 invention, qui permet que lorsque ladite fenêtre est ouverte, on puisse régler l'écartement relatif entre l'ouvrant (3) et l'élément mobile (4) grâce audites vis spéciales (5) disposées de manière à relier lesdits deux éléments (3 et 4). La partie de la vis se trouvant dans l'élément mobile (4)10 comporte un filetage perpendiculaire (6), qui interdit tout mouvement relatif de la vis (5) par rapport audit élément mobile (4) et la partie de la vis (5) vissée dans l'ouvrant (3) comporte un filetage hélicoïdal classique (7), les deux filetages étant séparés par une zone lisse (8). Ainsi, la rotation de ladite vis (5) provoque un mouvement relatif de l'élément mobile (4) par rapport à l'ouvrant (3). Grâce à la fenêtre (1) selon la présente invention, il est possible de régler de manière adéquate l'ouvrant (3) portant la gueule de loup par rapport à la partie ou ouvrant portant le mouton (2) et ainsi éviter tout coincement, ou au contraire éviter l'apparition d'un jeu trop important entre ces deux parties, ceci créant un très bon confort d'utilisation, et de très bonnes qualités d'étanchéité. A method of adjusting a wolf mouth window according to the present invention, which allows that when said window is open, the relative spacing between the opening (3) and the movable member (4) can be adjusted by means of audites special screws (5) arranged to connect said two elements (3 and 4). The portion of the screw in the movable element (4) has a perpendicular thread (6), which prevents any relative movement of the screw (5) with respect to said movable element (4) and the part of the screw ( 5) screwed into the opening (3) comprises a conventional helical thread (7), the two threads being separated by a smooth zone (8). Thus, the rotation of said screw (5) causes a relative movement of the movable member (4) relative to the opening (3). Thanks to the window (1) according to the present invention, it is possible to adjust adequately the opening (3) carrying the mouth of the wolf relative to the part or opening bearing the sheep (2) and thus avoid any jamming, or on the contrary avoid the appearance of a game too important between these two parts, this creating a very good comfort of use, and very good sealing qualities.

L'invention couvre également tous les modes de réalisation et toutes les applications qui seront directement accessibles à l'homme de métier à la lecture de la présente demande, et de ses connaissances propres. The invention also covers all the embodiments and all the applications which will be directly accessible to the person skilled in the art upon reading the present application, and of his own knowledge.
