Description

La présente invention concerne le domaine du chauffage de locaux, en particulier de locaux d'habita­tion, au moyen d'appareils de chauffage à foyer visible fermé, et a pour objet un foyer à insérer dans une che­minée à feu ouvert existante muni d'un dispositif de raccordement étanche escamotable.The present invention relates to the field of heating of premises, in particular of residential premises, by means of closed visible hearth heating appliances, and has for its object a hearth to be inserted into an existing open fire chimney provided with a retractable waterproof connection device.

Actuellement, les dispositifs de chauffage à feu visible peuvent essentiellement être rangés en deux groupes, à savoir les cheminées à feu ouvert et les che­minées à foyer visible fermé. Les cheminées du premier groupe ne présentent cependant, généralement, qu'un très faible rendement calorifique par rapport à celles du se­cond groupe, qui fonctionnent pratiquement comme des poêles et peuvent présenter une esthétique très proche des premières.Currently, visible fire heaters can essentially be classified into two groups, namely open fireplaces and closed visible fireplaces. The chimneys of the first group, however, generally have only a very low calorific efficiency compared to those of the second group, which function practically like stoves and can have an aesthetic very close to the first.

Pour des raisons d'économie de combustible et d'amélioration du rendement, il existe actuellement une tendance à pourvoir les foyers des cheminées à feu ou­vert d'un foyer fermé à feu visible à insérer dans ledit foyer ouvert.For reasons of fuel economy and efficiency improvement, there is currently a tendency to provide the hearths of open fireplaces with a closed hearth with visible fire to be inserted in said open hearth.

Certains de ces foyers à insérer sont montés librement dans la cheminée existante sans habillage com­plémentaire, et branchés sur le conduit de fumée exis­tant au moyen d'un tuyau flexible. Cependant, dans un tel cas, le foyer doit impérativement présenter une sec­tion frontale beaucoup plus petite que celle du foyer existant afin de permettre un branchement correct du tuyau flexible. Un tel foyer est connu de DE-C-70340.Some of these insert fireplaces are freely mounted in the existing chimney without additional cladding, and connected to the existing flue by means of a flexible pipe. However, in such a case, the hearth must imperatively have a much smaller front section than that of the existing hearth in order to allow correct connection of the flexible pipe. Such an outbreak is known from DE-C-70340.

Il est également prévu de monter des foyers, dont la fumée est évacuée directement dans l'avaloir de la cheminée existante, soit dans un cadre préalablement maçonné aux dimensions extérieures du foyer, soit en utilisant le foyer comme support et gabarit pour la ma­çonnerie. Toutefois, ce mode d'insertion d'un foyer fer­ mé dans une cheminée à feu ouvert nécessite des travaux de préparation relativement longs et coûteux, une maçonnerie réalisée préalablement étant difficile à effectuer, notamment du fait de la nécessité d'obtenir des côtés parfaitement perpendiculaires le moindre écart pouvant avoir des conséquences néfastes lors de la mise en place du foyer et nécessitant des réglages supplémen­taires d'aplomb, de profondeur et de centrage. En outre, dans le cas d'utilisation du foyer à insérer comme support pour la maçonnerie, le démontage dudit foyer devient très difficile, voire impossible à réaliser. GB-A-2 096 309 décrit un tel foyer à insérer dans une cheminée à feu ouvert existante, comportant un dispositif de mise en place et d'étanchéité. Mais ce dispositif ne permet que très difficilement un retrait total du foyer hors de la cheminée existante, car il n'est muni d'aucun dispositif le rendant amovible par simple glissement. US-A-4 191 162 a pour objet un foyer destiné à être fixé dans une ouverture de mur, mais n'est pas non plus muni d'un dispositif le rendant amovible par simple glissement. En outre, ce dernier foyer présente un encombrement en hauteur important au-dessus de l'âtre, nécessitant une hauteur de passage importante en conséquence pour son introduction dans le foyer existant, ce qui réduit d'autant la hauteur de l'ouverture visible du foyer inséré, la bande ouverte subsitante devant être couverte par un habillage étanche.It is also planned to mount fireplaces, the smoke of which is evacuated directly into the gutter of the existing chimney, either in a frame previously masonry to the external dimensions of the hearth, or by using the hearth as support and template for masonry. However, this method of inserting an iron hearth mé in an open fire requires relatively long and costly preparation work, masonry previously made is difficult to perform, in particular due to the need to obtain perfectly perpendicular sides the slightest deviation can have harmful consequences during the setting up the fireplace and requiring additional plumb, depth and centering adjustments. In addition, when using the fireplace to be inserted as a support for masonry, dismantling said fireplace becomes very difficult, if not impossible. GB-A-2 096 309 describes such a fireplace to be inserted in an existing open fire chimney, comprising a fitting and sealing device. However, this device only makes it very difficult to completely remove the hearth from the existing chimney, since it is not provided with any device making it removable by simple sliding. US-A-4 191 162 relates to a fireplace intended to be fixed in a wall opening, but is also not provided with a device making it removable by simple sliding. In addition, this latter hearth has a considerable size in height above the hearth, requiring a significant passage height consequently for its introduction into the existing hearth, which correspondingly reduces the height of the visible opening of the fireplace inserted, the remaining open strip to be covered by a waterproof covering.

Selon d'autres variantes de réalisation, le foyer à insérer est simplement muni d'un habillage, qui l'entoure et ferme les espaces libres du foyer existant. Un raccordement étanche d'un tel habillage avec le foyer à insérer et le foyer existant entraîne cependant des difficultés de réalisation quasiment insurmontables, no­tamment pour assurer l'étanchéité et donc la sécurité de l'usager.According to other alternative embodiments, the fireplace to be inserted is simply provided with a covering, which surrounds it and closes the free spaces of the existing fireplace. A tight connection of such a covering with the fireplace to be inserted and the existing fireplace however gives rise to almost insurmountable difficulties in production, in particular to ensure the sealing and therefore the safety of the user.

En outre, dans tous les cas, un retrait total du foyer à insérer hors de la cheminée existante, en vue d'une réparation du foyer ou d'une utilisation éventuel­le de ladite cheminée, par exemple en demi-saison, n'est pas possible sans d'importants travaux de réaménagement de cette dernière.In addition, in all cases, a total removal of the fireplace to be inserted out of the existing chimney, in order a repair of the fireplace or a possible use of the said chimney, for example in the mid-season, is not possible without major refurbishment of the latter.

De plus, lors de l'utilisation de foyers à insérer, il existe également des problèmes de ramonage du conduit de fumée ainsi que de retombée de suies autour du foyer avec le risque inhérent de combustion de ces suies.In addition, when using insert fireplaces, there are also problems with sweeping the flue as well as the fallout of soot around the fireplace with the inherent risk of combustion of this soot.

Enfin, les foyers connus de ce type ne permet­tent pas un raccordement à un conduit de fumée au moyen d'un tuyau de manière simple et rapide et sans perte im­portante de surface utile de la partie visible du foyer.Finally, known fireplaces of this type do not allow connection to a flue by means of a pipe in a simple and rapid manner and without significant loss of useful surface of the visible part of the hearth.

La présente invention a pour but de pallier ces inconvénients.The present invention aims to overcome these drawbacks.

Elle a, en effet, pour objet un foyer à insé­rer dans une cheminée à feu ouvert existante, caractéri­sé en ce qu'il est muni d'un dispositif de raccordement étanche escamotable, qui est essentiellement constitué par un châssis de réception et de guidage du foyer à in­sérer, et par un élément de fermeture étanche du pour­tour de la partie supérieure de sortie de fumée du foyer à insérer et de raccordement à un tuyau de branchement à un conduit de fumée.It has, in fact, the object of a hearth to be inserted into an existing open fire, characterized in that it is provided with a retractable sealed connection device, which is essentially constituted by a frame for receiving and guiding the fireplace to be inserted, and by a sealing element around the perimeter of the upper smoke outlet of the fireplace to be inserted and connection to a pipe connecting to a smoke duct.

L'invention sera mieux comprise grâce à la description ci-après, qui se rapporte à un mode de réa­lisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques an­nexés, dans lesquels :

  • la figure 1 est une vue en élévation latérale et en coupe du foyer conforme à l'invention ;
  • la figure 2 est une demi-vue en coupe et en élévation frontale du dispositif de raccordement, et
  • la figure 3 est une vue en coupe et en détail d'un moyen de réglage de l'élément de fermeture étanche.
The invention will be better understood thanks to the description below, which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawings, in which:
  • Figure 1 is a side elevational view in section of the hearth according to the invention;
  • FIG. 2 is a half-view in section and in front elevation of the connection device, and
  • Figure 3 is a sectional and detailed view of an adjusting means of the sealed closure member.

Conformément à l'invention, et comme le mon­trent plus particulièrement, à titre d'exemple, les fi­gures 1 et 2 des dessins annexés, le foyer à insérer dans une cheminée à feu ouvert existante est muni d'un dispositif de raccordement étanche escamotable, qui est essentiellement constitué par un châssis 1 de réception et de guidage du foyer à insérer 2 et de raccordement, et par un élément 3 de fermeture étanche du pourtour de 1a partie supérieure de sortie de fumée 4 du foyer à in­sérer 2 et de raccordement à un tuyau de branchement à un conduit de fumée.According to the invention, and as shown more particularly, by way of example, Figures 1 and 2 of the accompanying drawings, the fireplace to be inserted in an existing open fireplace is provided with a retractable waterproof connection device, which essentially consists of a frame 1 for receiving and guiding the fireplace to be inserted 2 and for connection, and by an element 3 for sealing the perimeter 1a upper smoke outlet part 4 of the fireplace to insert 2 and connection to a pipe connecting to a smoke duct.

Le châssis 1 est avantageusement constitué par un assemblage de montants et de traverses profilés pou­vant être insérés dans l'ouverture de la cheminée exis­tante, dont deux profilés de l'embase sont sous forme de cornières 5 de guidage de la base du foyer à insérer 2, et dont les profilés formant la face avant du châssis 1 sont également sous forme de cornières et s'appliquent par leur aile contre le pourtour de l'ouverture de la cheminée existante. Ainsi, un guidage parfait du foyer 2 est assuré lors de sa mise en place, grâce aux cornières 5 et les cornières délimitant la place avant du châssis 1 permettent un recouvrement parfait du pourtour de l'ouverture de la cheminée existante.The frame 1 is advantageously constituted by an assembly of uprights and profiled crosspieces which can be inserted into the opening of the existing chimney, two profiles of the base of which are in the form of angles 5 for guiding the base of the hearth to be inserted 2 , and whose profiles forming the front face of the frame 1 are also in the form of angles and are applied by their wing against the periphery of the opening of the existing chimney. Thus, perfect guidance of the hearth 2 is ensured during its installation, thanks to the angles 5 and the angles delimiting the front place of the frame 1 allow perfect covering of the periphery of the opening of the existing chimney.

L'élément 3 de fermeture étanche du pourtour de la partie supérieure de sortie de fumée 4 du foyer à insérer 2 est avantageusement monté de manière pivotable sur la partie arrière du châssis 1 au moyen de pattes 6 et est essentiellement constitué par un cadre 7 d'appli­cation sur la sortie de fumée du foyer 2, muni d'un joint d'étanchéité périphérique 12, par un avaloir 8 so­lidaire du cadre 7 par soudure, par une buse 9 de rac­cordement à un tuyau de branchement, pourvu d'un clapet 10 de réglage de tirage, et par des moyens 11 de main­tien réglable de l'élément 3 par rapport au châssis 1 et au foyer à insérer 2.The element 3 for sealing around the periphery of the upper smoke outlet 4 of the insert 2 is advantageously pivotally mounted on the rear part of the frame 1 by means of lugs 6 and is essentially constituted by a frame 7 d 'application to the smoke outlet of the hearth 2, provided with a peripheral seal 12, by a drain 8 secured to the frame 7 by welding, by a nozzle 9 for connection to a connection pipe, provided with a valve 10 for draft adjustment, and by means 11 for holding the element 3 adjustable relative to the chassis 1 and to the insert 2.

Grâce à ce mode de réalisation, il est possi­ble d'insérer le dispositif de raccordement dans une cheminée à feu ouvert dont la hauteur de l'ouverture de foyer est inférieure à la hauteur du dispositif en po­sition de service.Thanks to this embodiment, it is possible to insert the connection device into an open fireplace whose height of the fireplace opening is less than the height of the device in the service position.

Chaque moyen 11 de maintien réglable de l'élément 3 est avantageusement constitué par un ensem­ble de biellettes de réglage 13 et de soutien 14, qui est articulé par une extrémité, par la biellette de ré­glage 13, à une patte 15 solidaire du cadre 7, et fixé par son autre extrémité, par la biellette de soutien 14, à une traverse du châssis 1 (figures 1 et 3), la biel­lette de réglage 13 présentant une longueur inférieure à celle de la biellette de soutien 14 et étant reliée à cette dernière, près de son extrémité opposée à la patte 15 au moyen d'un boulon 19 traversant la biellette 14 et un trou oblong 16 de ladite extrémité, la biellette 14 étant, en outre, pourvue, à son extrémité correspondant à l'articulation à la patte 15, d'une fente de guidage ouverte 17 entourant l'axe 18 d'articulation à la patte 15. Ainsi, la position d'application de l'élément 3 sur le foyer à insérer peut avantageusement être réglée, avant montage dans le foyer de cheminée 2, au moyen des ensembles de biellettes 13 et 14 par simple réglage de ces dernières entre elles, par coulissement, puis ser­rage au moyen du boulon 19, l'extrémité libre des biel­lettes 14 étant fixée à la traverse correspondante du châssis 1. Après ce réglage, il suffit de démonter l'extrémité des biellettes 14 fixée sur les traverses et d'escamoter l'élément 3 à l'intérieur du châssis l, par basculement, puis de monter le dispositif dans le foyer de la cheminée existante, de pivoter l'élément 3 dans sa position de service et de le fixer dans cette position grâce aux moyens 11, de pourvoir la buse 9, simultané­ment, d'un tuyau de raccordement à un conduit de fumée, puis de glisser le foyer 2, sur les cornières 5, dans le dispositif jusqu'à ce que sa partie supérieure 4 porte contre le joint d'étanchéité 12 de l'élément 3.Each adjustable means 11 for holding the element 3 advantageously consists of a set of adjustment rods 13 and of support 14, which is articulated at one end, by the adjustment rod 13, to a lug 15 integral with the frame 7, and fixed by its other end, by the support link 14, to a cross member of the chassis 1 (FIGS. 1 and 3), the adjustment link 13 having a length shorter than that of the support link 14 and being connected to the latter , near its end opposite the lug 15 by means of a bolt 19 passing through the link 14 and an oblong hole 16 from said end, the link 14 being, moreover, provided, at its end corresponding to the articulation at the lug 15, an open guide slot 17 surrounding the axis 18 of articulation to the lug 15. Thus, the position of application of the element 3 on the hearth to be inserted can advantageously be adjusted, before mounting in the fireplace hearth 2, by means of connecting rod assemblies ettes 13 and 14 by simple adjustment of the latter between them, by sliding, then tightening by means of the bolt 19, the free end of the rods 14 being fixed to the corresponding cross member of the chassis 1. After this adjustment, it suffices to disassemble the end of the rods 14 fixed on the crosspieces and to retract the element 3 inside the frame l, by tilting, then to mount the device in the hearth of the existing chimney, to pivot the element 3 in its position service and fix it in this position using the means 11, to provide the nozzle 9, simultaneously, with a pipe for connection to a smoke duct, then to slide the hearth 2, on the angles 5, into the device until 'that its upper part 4 bears against the seal 12 of the element 3.

Le montage du tuyau de fumée est particuliè­rement aisé du fait qu'on peut y accéder à travers la buse 9 et l'espace libre correspondant à celui du foyer à insérer proprement dit.The assembly of the smoke pipe is particularly easy because it can be accessed through the nozzle 9 and the free space corresponding to that of the fireplace to be inserted itself.

Afin d'assurer un maintien correct du foyer 2 dans le châssis 1 et contre l'élément 3, le foyer 2 est fixé à l'élément 3 par au moins une vis 20 (figure 1).To ensure proper maintenance of the fireplace 2 in the frame 1 and against the element 3, the hearth 2 is fixed to the element 3 by at least one screw 20 (FIG. 1).

Selon une autre variante de réalisation de l'invention, non représentée aux dessins annexés, les moyens 11 peuvent également être réalisés sous forme d'éléments télescopiques pouvant être bloqués en posi­tion entre eux.According to another alternative embodiment of the invention, not shown in the accompanying drawings, the means 11 can also be produced in the form of telescopic elements which can be locked in position with one another.

Grâce à l'invention, il est possible de réali­ser un foyer à insérer dans une cheminée à feu ouvert existante, muni d'un dispositif de raccordement étanche escamotable, permettant une utilisation maximale de la surface de foyer existante comme surface d'ouverture vi­sible du foyer inséré, tout en assurant un branchement simple et efficace dudit foyer à un conduit de fumée au moyen d'un tuyau. En outre, le mode de réalisation con­forme à l'invention permet un ramonage simplifié et ra­pide, par simple retrait du foyer 2 hors du châssis 1.Thanks to the invention, it is possible to produce a hearth to be inserted into an existing open fireplace, provided with a retractable waterproof connection device, allowing maximum use of the existing hearth surface as the visible opening surface of the fireplace inserted, while ensuring a simple and efficient connection of said fireplace to a flue by means of a pipe. In addition, the embodiment in accordance with the invention allows a simplified and rapid sweeping, by simple removal of the hearth 2 from the chassis 1.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins an­nexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments, ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements, or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
