Description

La présente invention vise, d'une manière générale, les appareils générateurs de chaleur fonctionnant au gaz, dits étanches, et à pour objet un dispositif pour raccorder ceux-ci à l' extérieur d'une construction.The present invention relates, in general, heat generating devices operating on gas, said to be waterproof, and for their object a device for connecting them to the outside of a construction.

Pour raccorder avec l'extérieur les appareils étanches du genre ci-dessus, qui sont, de manière usuelle, disposés à l'intérieur d'un local, on a déjà proposé d'équiper chaque appareil d'une ventouse.To connect with the waterproof devices of the above type, which are usually arranged inside a room, it has already been proposed to equip each device with a suction cup.

De telles ventouses comprennent deux éléments tubulaires, coaxiaux destinés à être engagés dans une ouverture pratiquée dans une paroi, par exemple un mur de façade ; à une de leurs extrémités, du côté extérieur à la paroi les éléments sont équipés d'un nez de ventouse, et à leurs autres extrémités, côté local, Ils sont raccordés à l'appareil étanche qui est lui-même porté par la paroi.Such suction cups comprise two tubular, coaxial elements intended to be engaged in an opening made in a wall, for example a front wall; at one of their ends, on the side outside the wall, the elements are fitted with a suction cup nose, and at their other ends, on the local side, they are connected to the waterproof device which is itself carried by the wall.

Actuellement, le montage de la ventouse d'une part, ainsi que le montage des appareils étanches d'autre part, demandent des temps d'intervention relativement longs, qui se répercutent sur le prix de revient. Il a été observé en outre que l' étanchéité de la ventouse entre l'extérieur et l'intérieur du local laissait à désirer, notamment en fonction de l'exposition.Currently, the mounting of the suction cup on the one hand, as well as the mounting of waterproof devices on the other hand, require relatively long intervention times, which have repercussions on the cost price. It was further observed that the tightness of the suction cup between the outside and the inside of the room left something to be desired, in particular depending on the exposure.

La présente Invention a pour objet un dispositif pour raccorder à l'extérieur d'une construction un appareil étahche fonctionnant au gaz dans lequel les inconvénients énoncés succinctement plus avant sont supprimés.The present invention relates to a device for connecting to the outside of a construction a gas-powered waterproof appliance in which the drawbacks described briefly above are eliminated.

A cet effet, un dispositif pour raccorder à l'extérieur d'une construction un appareil étanche fonctionnant au gaz, du genre comprenant une ventouse ayant deux éléments tubulaires disposés coaxialement pour ménager deux conduits, l'un étant un conduit pour l'admission d'air de combustion à l'appareil, et l'autre, un conduit pour l'évacuation des gaz de combustion, lesdits éléments tubulaires dits par commodité externe, et interne, étant adaptés à être raccordés à l'appareil par une de leurs extrémités, et à déboucher par leurs autres extrémités à l'extérieur au moyen d'un nez de ventouse, se caractérise par le fait que du côté opposé au nez de ventouse qui est monobloc, l'élément tubulaire externe reçoit par emboltement, sans Jeu, une plaque support qui comporte, à distance de la zone d'emboîtement, des moyens propres à sa fixation à une paroi, ainsi que des moyens aptes à coopérer avec des moyens complémentaires prévus sur l'appareil pour d'une part, immobiliser celui-ci par rapport à la ventouse et, d'autre part, assurer sa fixation à ladite paroi.To this end, a device for connecting outside a building a gas-tight device, of the type comprising a suction cup having two tubular elements arranged coaxially to provide two conduits, one being a conduit for the admission of combustion air to the appliance, and the other, a duct for the evacuation of combustion gases, said tubular elements known as external and internal convenience, being adapted to be connected to the appliance by one of their ends , and to lead out by their other ends to the outside by means of a suction cup nose, is characterized by the fact that on the side opposite to the suction cup nose which is in one piece, the external tubular element receives by embedding, without clearance, a support plate which comprises, at a distance from the interlocking zone, means suitable for fixing it to a wall, as well as means suitable for cooperate with additional means provided on the device to firstly immobilize it relative to the suction cup and, secondly, ensure its attachment to said wall.

La pose d'un appareil étanche avec un dispositif suivant l'invention, est notablement simplifiée comparativement à la technique antérieure, en particulier par le fait que la plaque de support de l'appareil est placée automatiquement par emboîtement sur l'élément externe de la ventouse, puis fixée à la paroi de manière usuelle; comme par ailleurs, la plaque en question est immobilisée axialement sur la ventouse par un collier à serrage rapide, on conçoit que la pose d'un appareil étanche avec un dispositif suivant l'invention est réduite à des opérations simples (perçages et assemblages) qui peuvent être rapidement exécutées sans précautions particulières.The installation of a waterproof device with a device according to the invention is considerably simplified compared to the prior art, in particular by the fact that the support plate of the device is placed automatically by interlocking on the external element of the suction cup, then fixed to the wall in the usual way; as, moreover, the plate in question is immobilized axially on the suction cup by a quick-clamping collar, it can be seen that the fitting of a sealed device with a device according to the invention is reduced to simple operations (drilling and assemblies) which can be quickly performed without special precautions.

Pour ce qui concerne l'étanchéité, la configuration du nez de ventouse monobloc, des éléments tubulaires, ainsi que le montage de l'appareil sur la ventouse, autorise la mise en place et l'aménagement de moyens d'étanchéité particulièrement efficaces.As regards sealing, the configuration of the one-piece suction cup nose, of the tubular elements, as well as the mounting of the device on the suction cup, allows the installation and arrangement of particularly effective sealing means.

D'autres caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui va suivre, donnée à titre d'exemple, en référence aux dessins annexés dans lesquels :

  • la figure 1 est une vue en élévation verticale, avec parties en coupe, d'une forme de réalisation du dispositif selon 1'invention ;
  • la figure 2 montre de face le nez de ventouse ;
  • la figure 3 est une vue en coupe de ce nez de ventouse suivant la ligne III-III de la figure 2 ;
  • la figure 4 montre en perspective la plaque support et, partiellement les moyens équipant chaque appareil pour son centrage automatique et sa fixation à ladite plaque support.
Other characteristics and advantages of the invention will also emerge from the description which follows, given by way of example, with reference to the appended drawings in which:
  • Figure 1 is a vertical elevational view, in section, of an embodiment of the device according to the invention;
  • Figure 2 shows a front view of the suction cup nose;
  • Figure 3 is a sectional view of the suction cup nose along line III-III of Figure 2;
  • Figure 4 shows in perspective the support plate and, partially the means equipping each device for its automatic centering and its attachment to said support plate.

Suivant la forme de réalisation choisie et représentée à la figure 1, un dispositif selon l'invention est montré en place dans une paroi P ; il comprend une ventouse constituée d'un nez de ventouse 12 et de deux éléments tubulaires coaxiaux appelés par commodité respectivement externe 10, et interne 11.Depending on the embodiment chosen and shown in Figure 1, a device according to the invention is shown in place in a wall P; it comprises a suction cup consisting of a suction cup nose 12 and two coaxial tubular elements called for convenience respectively external 10, and internal 11.

Le nez de ventouse 12 qui est monobloc, en matière moulée comprend une première jupe 13 extérieure, et une seconde jupe 14 intérieure qui sont réunies au moyen de barreaux radiaux 15 régulièrement espacés de manière à former une pluralité de passages 17.The suction cup nose 12 which is in one piece, of molded material comprises a first outer skirt 13, and a second inner skirt 14 which are joined by means of radial bars 15 regularly spaced so as to form a plurality of passages 17.

La jupe intérieure 14 présente une partie terminale dépassante par rapport à une extrémité de la jupe extérieure 13, et cette partie terminale saillante est fermée à son extrémité, par une cloison 18 ; périphériquement la jupe 14 comporte dans sa partie dépassante une pluralité de lumières longitudinales 19.The inner skirt 14 has an end portion projecting relative to one end of the outer skirt 13, and this projecting end portion is closed at its end, by a partition 18; peripherally the skirt 14 has in its projecting part a plurality of longitudinal slots 19.

Quant à la jupe extérieure 13, elle comporte une plage circulaire dans laquelle est ménagé un bossage 22 apte à former par son creux annulaire un logement pour un joint d'étanchéité 23 (figure 1), tandis que par sa face extérieure ce bossage empêche que les eaux de pluie ruisselante sur la façade pénètrent à l'intérieur de la ventouse.As for the outer skirt 13, it has a circular area in which is formed a boss 22 capable of forming by its annular recess a housing for a seal 23 (Figure 1), while by its outer face this boss prevents that the dripping rainwater on the facade enters the interior of the suction cup.

Par aillaurs, la structure de l'ensemble du nez de ventouse offre une résistance convenable aux chocs.In addition, the structure of the entire suction cup nose provides adequate impact resistance.

Enfin, les éventuels défauts périphériques du passage ménagé dans la paroi sont escamotés par la plage circulaire.Finally, any peripheral faults of the passage formed in the wall are retracted by the circular area.

Le dispositif suivant l'invention comprend aussi une plaque support 30 bien visible en particulier à la figure 4.The device according to the invention also includes a clearly visible support plate 30, in particular in FIG. 4.

Cette plaque support, avantageusement réalisée en tôle, comprend une embase 30A dans laquelle est ménagé un trou 30B. L'embase comporte aussi, à distance du trou 30B des moyens propres à la fixation de la plaque support sur la paroi P, en l'espèce un mur de façade, ces moyens étant constitués ici par deux lumières 36 en forme de haricot dont l'axe en secteur de cercle a un rayon dont le centre correspond à celui de l'ouverture 30B.This support plate, advantageously made of sheet metal, comprises a base 30A in which a hole 30B is formed. The base also includes, at a distance from the hole 30B, means suitable for fixing the support plate to the wall P, in this case a front wall, these means being constituted here by two bean-shaped slots 36, the l the axis in a circle sector has a radius whose center corresponds to that of the opening 30B.

Dans un plan perpendiculaire à son embase le support 30 est prolongé par deux retours latéraux 30C ; dans chacun de ces retours sont ménagées par découpes 30D des pattes 30E perpendiculaires au plan général du support, et des pattes 30F, ces dernières étant orientées parallèlement à l'embase et aménagées avec un passage 30G.In a plane perpendicular to its base, the support 30 is extended by two lateral returns 30C; in each of these returns are formed by cutouts 30D of the legs 30E perpendicular to the general plane of the support, and of the legs 30F, the latter being oriented parallel to the base and arranged with a passage 30G.

L'appareil étanche A -bien connu en soi- est représenté partiellement Ici par des traits discontinus ; un tel appareil comprend, sur sa face dorsale, et dans sa partie Inférieure deux fers latéraux 35 (un seul étant représenté) chacun ayant une aile 35A dans laquelle sont ménagés respectivement une lumière verticale allongée 35B et un trou 35C ; les lumières précitées 35B sont prévues de manière à s'emboîter pratiquement sans jeu sur les ailes 30E des retours, tandis que les trous 35C sont disposés de manière à se trouver devant les trous 30G des ailes 30E , 30F.The waterproof device A - well known in the art - is partially represented here by broken lines; such an apparatus comprises, on its dorsal face, and in its lower part two lateral irons 35 (only one being shown) each having a wing 35A in which an elongated vertical light 35B and a hole 35C are provided respectively; the aforementioned lights 35B are provided so as to fit practically without play on the wings 30E of the returns, while the holes 35C are arranged so as to be in front of the holes 30G of the wings 30E, 30F.

On observe que, du côté où Ils sont destinés à s'emboîter sur les jupes 13, 14, du nez de ventouse 12 les éléments tubulaires externe 10 et interne 11 comportent chacun une gorge périphérique rentrante 40, 41 ; les gorges précitées sont décalées axialement en sorte que la gorge 40 se trouve au-delà de l'autre gorge 41, en prenant pour référence la façade de la paroi P.It is observed that, on the side where they are intended to fit onto the skirts 13, 14, of the suction cup nose 12, the external 10 and internal 11 tubular elements each have a re-entrant peripheral groove 40, 41; the aforementioned grooves are offset axially so that the groove 40 is located beyond the other groove 41, taking as a reference the front of the wall P.

Le dispositif comprend en outre un collier 42 propre à l' immobilisation axiale de la ventouse en place dans la paroi, et un Joint 43 adapté à être engagé sur l'élément tubulaire externe entre la paroi et l'appareil A. On note que, tel que représenté, le Joint 43 est apte d'une part, à coopérer avec la surface extérieure de l'élément externe 10 de la ventouse et, d'autre part, à être engagé par une gorge 45 qu'il comporte sur le bord circulaire du trou 30B ménagé dans le support 30.The device further comprises a collar 42 suitable for the axial immobilization of the suction cup in place in the wall, and a seal 43 adapted to be engaged on the external tubular element between the wall and the device A. It is noted that, as shown, the Seal 43 is suitable on the one hand, for cooperating with the external surface of the external element 10 of the suction cup and, on the other hand, for being engaged by a groove 45 which it comprises on the edge circular of the hole 30B made in the support 30.

L'élément tubulaire externe 10 étant engagé et solidarisé avec la jupe correspondante du nez de ventouse 12, ces deux pièces sont engagées, par la façade de la paroi P, dans un passage ménagé à un endroit choisi après mise en place du joint d'étanchéité 23 inséré dans le logement en creux formé par le bossage 22.The external tubular element 10 being engaged and secured to the corresponding skirt of the suction cup nose 12, these two parts are engaged, by the facade of the wall P, in a passage formed at a chosen location after fitting the gasket. seal 23 inserted in the hollow housing formed by the boss 22.

Le Joint 43 est engagé dans le bord périphérique du trou 30B de la plaque support 30, puis la plaque ainsi équipée est engagée sur l'élément tubulaire externe 10, et l'ensemble élément tubulaire externe 10 et plaque support 30 est immobilisé au moyen du collier 42 serré sur l'élément externe; ledit élément externe peut alors être tronçonné au voisinage dudit joint 43. L'élément tubulaire interne 11 est alors em- boité sur la jupe intérieure puis sectionné à longueur convenable.The seal 43 is engaged in the peripheral edge of the hole 30B of the support plate 30, then the plate thus equipped is engaged on the external tubular element 10, and the assembly of external tubular element 10 and support plate 30 is immobilized by means of the collar 42 tightened on the external element; said external element can then be cut off in the vicinity of said joint 43. The internal tubular element 11 is then fitted to the internal skirt and then sectioned to a suitable length.

On remarque que l'étanchéité entre ventouse et paroi P est assurée en façade par le joint 23 et à l'arrière par le Joint 43.It is noted that the seal between the suction cup and the wall P is ensured on the front by the seal 23 and at the rear by the seal 43.

De même, les gorges rentrantes 40, 41, forment un barrage aux eaux de pluie et empêchent celles-ci de pénétrer plus en arrière dans la ventouse, donc à l'intérieur de l'appareil.Similarly, the re-entrant grooves 40, 41 form a barrier to rainwater and prevent it from penetrating further back into the suction cup, therefore inside the device.

La plaque support 30 qui est donc en attente est convenablement orientéepar balancement autour de l'élément externe 10 puis, elle est fixée de manière usuelle à la paroi P, à l' aide de vis V engagées dans les trous 36 après quoi l'appareil étanche A est engagé sur les éléments 10, 11, de la ventouse et fixé à la plaque support 30 par engagement des ferrures 35 qu'il comporte sur les pattes 30E prévues à cet effet dans les retours 30C de la plaque support.The support plate 30 which is therefore on standby is suitably oriented by rocking around the external element 10 then, it is fixed in the usual way to the wall P, using screws V engaged in the holes 36 after which the apparatus watertight A is engaged on the elements 10, 11, of the suction cup and fixed to the support plate 30 by engagement of the fittings 35 which it comprises on the lugs 30E provided for this purpose in the returns 30C of the support plate.

Des vis ou autres boulons 38 assurent la fixation de l' appareil étanche qui est donc emboîté dans sa partie supérieure sur les éléments tubulaires 10, 11, de la ventouse, et assemblé dans sa partie inférieure avec la plaque support.Screws or other bolts 38 secure the sealed device which is therefore fitted in its upper part on the tubular elements 10, 11, of the suction cup, and assembled in its lower part with the support plate.

On observera que le montage de la ventouse et de l'appareil étanche à gaz est particulièrement aisé sans risque possible d'erreur, notamment du fait que la pose de la plaque support 30 est obtenue à la suite d'un seul réglage de sa position (pivotement autour de l'élément externe 10), ce qui évite le recours à un traçage au gabarit, et à diverses opérations, avec les risques d'erreur qu'elles comportent.It will be observed that the mounting of the suction cup and of the gas-tight device is particularly easy without possible risk of error, in particular because the fitting of the support plate 30 is obtained after a single adjustment of its position. (pivoting around the external element 10), which avoids the use of a template tracing, and various operations, with the risks of error that they entail.

En d'autres termes,l'association de la plaque support 30 avec la ventouse définit de manière sûre la position de l'appareil étanche fonctionnant au gaz, ainsi que sa fixation dans une telle position.In other words, the association of the support plate 30 with the suction cup surely defines the position of the gas-tight sealed appliance, as well as its fixing in such a position.

Ainsi qu'on le voit, de manière usuelle, l'air nécessaire à la combustion est introduit dans l'appareil A par le conduit annulaire ménagé entre les deux éléments externe et interne, tandis que l'évacuation à l'extérieur des gaz de combustion est assuré par le conduit central formé par l'élément tubulaire Interne.As can be seen, in the usual way, the air necessary for combustion is introduced into the apparatus A by the con annular duit formed between the two external and internal elements, while the discharge to the outside of the combustion gases is ensured by the central duct formed by the internal tubular element.

Bien entendu l'invention n'est pas limitée à l'exemple de réalisation choisi et représenté, lequel est au contraire susceptible de diverses modifications, sans pour autant sortir du cadre de la présente invention.Of course, the invention is not limited to the embodiment chosen and shown, which is on the contrary subject to various modifications, without however departing from the scope of the present invention.
