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 mise en place et d'étanchéité le rendant parfaitement amovible.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 fitting and sealing device making it perfectly removable.

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 saving fuel and improving efficiency, there is currently a tendency to provide fireplaces in open fireplaces with a closed fireplace with visible fire to be inserted in said fireplace. open.

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.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.

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 fermé 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.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 a closed hearth into an open fireplace requires relatively long and costly preparation work, masonry previously made being difficult to perform, in particular due to the need to obtain perfectly perpendicular sides. , the slightest deviation could have harmful consequences during the installation of 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.

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.

Enfin, 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.Finally, in all cases, a total removal of the fireplace to be inserted outside the existing chimney, with a view to repairing the fireplace or possible use of the said chimney, for example in the mid-season, is not possible without major refurbishment of the latter.

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 mise en place et d'étanchéité le rendant parfaitement amovible.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 fitting and sealing device making it perfectly removable.

Conformément à une caractéristique de l'invention, le dispositif de mise en place et d'étanchéité est constitué par des glissières horizontales fixées sur la sole de la cheminée existante, par un cadre vertical lié aux glissières perpendiculairement à leur plan, par un aménagement avant dUr-foyer amovible coopérant avec le cadre vertical et destiné à assurer l'étanchéité par écrasement d'un joint, et par un dispositif favorisant le glissement de la partie inférieure du foyer amovible sur les glissières horizontales.According to a characteristic of the invention, the installation and sealing device is constituted by horizontal slides fixed to the floor of the existing chimney, by a vertical frame linked to the slides perpendicular to their plane, by a front arrangement. dUr-removable hearth cooperating with the vertical frame and intended to ensure sealing by crushing a seal, and by a device promoting the sliding of the lower part of the removable hearth on the horizontal slides.

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 perspective éclatée d'un foyer à insérer conforme à l'invention ;
  • la figure 2 est une vue partielle en coupe montrant la liaison étanche entre foyer et cadre au niveau d'un montant ;
  • la figure 3 représente une variante de réalisation de la liaison suivant la figure 2, et
  • la figure 4 est une vue partielle en coupe d'une partie de fond du foyer.

  • Figure 4 is a partial sectional view of a bottom portion of the hearth.

Conformément à l'invention, et comme le montre plus particulièrement, à titre d'exemple, la figure 1 des dessins annexés, le foyer 4 à insérer dans une cheminée à feu ouvert existante est muni d'un dispositif de mise en place et d'étanchéité, qui le rend parfaitement amovible.In accordance with the invention, and as shown more particularly, by way of example, FIG. 1 of the accompanying drawings, the hearth 4 to be inserted in a chemi Born on an existing open fire, it is fitted with a fitting and sealing device, which makes it perfectly removable.

Ce dispositif est avantageusement constitué par des glissières horizontales 1, qui sont fixées sur la sole de la cheminée existante au moyen de vis traversant des perçages 7 prévus à cet effet, par un cadre vertical 2 relié aux glissières 1 perpendiculairement à leur plan, et par un aménagement avant 3 du foyer amovible 4, qui coopère avec le cadre vertical 2. et qui est destiné à assurer l'étanchéité par écrasement d'un joint 5. La partie inférieure du foyer amovible 4 est pourvue, en outre, d'un dispositif 6 favorisant son glissement sur les glissières 1.This device is advantageously constituted by horizontal rails 1, which are fixed to the hearth of the existing chimney by means of screws passing through holes 7 provided for this purpose, by a vertical frame 2 connected to the rails 1 perpendicular to their plane, and by a front arrangement 3 of the removable hearth 4, which cooperates with the vertical frame 2. and which is intended to ensure the sealing by crushing of a seal 5. The lower part of the removable hearth 4 is further provided with a device 6 promoting its sliding on the slides 1.

Le cadre vertical 2 est avantageusement fixé aux glissières 1 de manière démontable au moyen d'éléments 8, en fer plat, ou autre, s'étendant obliquement d'une glissière 1 au montant correspondant du cadre 2, et fixés, de préférence, au moyen de vis, une liaison par vis pouvant également être prévue au niveau de la jonction de la base de chaque montant avec l'extrémité correspondante des glissières 1.The vertical frame 2 is advantageously fixed to the slides 1 in a removable manner by means of elements 8, of flat iron, or other, extending obliquely from a slide 1 to the corresponding amount of the frame 2, and preferably fixed to the screw means, a screw connection can also be provided at the junction of the base of each upright with the corresponding end of the slides 1.

Ces dernières sont reliées, à leur extrémité opposée au cadre vertical 2, à une traverse 9.The latter are connected, at their end opposite to the vertical frame 2, to a cross-member 9.

L'aménagement avant 3 du foyer amovible 4 est constitué par un cadre rapporté 10 s'appliquant sur les montants et sur la traverse supérieure du foyer amovible 4 et portant le joint 5, qui est écrasé sur le cadre vertical 2, lors de l'insertion complète du foyer amovible 4 (figure 2).The front arrangement 3 of the removable hearth 4 is constituted by an attached frame 10 applying to the uprights and to the upper cross member of the removable hearth 4 and carrying the seal 5, which is crushed on the vertical frame 2, during the complete insertion of the removable hearth 4 (Figure 2).

Conformément à une variante de réalisation de l'invention, et comme le montre la figure 3 des dessins annexés, l'aménagement avant 3 peut également être constitué par des parties repliées 11 des bords latéraux et de la traverse supérieure du foyer amovible 4, le joint 5 étant logé dans lesdites parties repliées 11.According to an alternative embodiment of the invention, and as shown in Figure 3 of the accompanying drawings, the front arrangement 3 may also consist of folded parts 11 of the side edges and of the upper cross member of the removable hearth 4, the seal 5 being housed in said folded parts 11.

Le dispositif 6, équipant la partie inférieure du foyer amovible 4 (figure 4), est avantageusement constitué par des rebords 12 des parois verticales latérales du foyer 4, qui sont rabattus sur le fond de ce dernier et forment chacun une surface parfaitement plane d'application sur les glissières 1.The device 6, fitted to the bottom of the removable hearth 4 (Figure 4), is advantageously constituted by the flanges 12 of the vertical side walls of the furnace 4, which are folded on the bottom of the latter and each form a perfectly plane surface application on runners 1.

Pour favoriser ce glissement, les rebords 12 sont, de préférence, munis d'un revêtement anti-adhérent, tel que du polytétrafluoréthylène, ou analogue.To promote this sliding, the edges 12 are preferably provided with a non-stick coating, such as polytetrafluoroethylene, or the like.

Il est également possible de réaliser le dispositif 6 par prévision de chemins de billes ou de galets (non représentés), le long des parties latérales de fond du foyer amovible 4 opposées aux glissières 1.It is also possible to produce the device 6 by providing paths for balls or rollers (not shown), along the side parts of the bottom of the removable hearth 4 opposite the slides 1.

Le cadre vertical 2, dont les montants sont reliés à leur base par une traverse en fer plat 13, présente avantageusement des dimensions identiques à celles du foyer amovible 4 en hauteur et en largeur avec un léger jeu de fonctionnement, et l'élément horizontal, formé par les glissières 1 et par leur traverse de liaison 9, présente des dimensions équivalentes à celles de la base du foyer amovible 4 à insérer, également avec un léger jeu de fonctionnement, et les glissières 1 sont, de préférence, en forme de cornière, et font office de rails de guidage.The vertical frame 2, the uprights of which are connected to their base by a flat iron cross-member 13, advantageously has dimensions identical to those of the removable hearth 4 in height and in width with a slight operating clearance, and the horizontal element, formed by the slides 1 and by their connecting crosspiece 9, has dimensions equivalent to those of the base of the removable hearth 4 to be inserted, also with a slight operating clearance, and the slides 1 are preferably in the form of an angle , and act as guide rails.

-Pour assurer un maintien parfait du cadre 2 et des glissières 1 sur la sole de cheminée existante, en particulier après positionnement, les glissières 1 ainsi que la traverse inférieure 13 du cadre 2 sont avantageusement munies d'un ou de plusieurs perçages 7 pour des vis de scellement (non représentées).-To ensure perfect retention of the frame 2 and the rails 1 on the existing chimney hearth, in particular after positioning, the rails 1 as well as the lower cross member 13 of the frame 2 are advantageously provided with one or more holes 7 for sealing screws (not shown).

En outre, pour garantir le scellement du cadre dans la maçonnerie de fermeture de l'ouverture de foyer existante, les montants du cadre vertical 2 sont avanta- . geusement pourvus, soit chacun d'une ou de plusieurs pattes de scellement 14, soit d'une ou de plusieurs pattes repliables 15 munies chacune d'un trou 16 de fixation par vis pour la fixation du cadre 2 sur l'intérieur des parois verticales de la cheminée existante.In addition, to guarantee the sealing of the frame in the masonry closing the existing fireplace opening, the uprights of the vertical frame 2 are advantageous. suitably provided, either each with one or more sealing tabs 14, or with one or more folding legs 15 each provided with a hole 16 for fixing by screws for fixing the frame 2 on the inside of the vertical walls of the existing chimney.

Sur sa face avant, le cadre vertical 2 est muni, éventuellement, à intervalles réguliers, de trous taraudés 17 permettant l'immobilisation et la fixation au moyen de vis du foyer amovible 4 à insérer, après sa mise en place, et évitant ainsi un déplacement accidentel dudit foyer.On its front face, the vertical frame 2 is possibly provided, at regular intervals, with tapped holes 17 allowing immobilization and fixing by means of screws of the removable hearth 4 to be inserted, after its installation, and thus avoiding a accidental displacement of said focus.

L'étanchéité entre le foyer amovible 4 à insérer et le cadre vertical 2 est assurée par un joint unique 5 rapporté sur le cadre vertical 2, ou encore équipant ledit foyer 4, tandis que l'étanchéité entre le cadre 2 et le foyer ouvert de la cheminée existante est assurée par la maçonnerie s'appuyant contre le cadre 2 (figuré 2), cette maçonnerie pouvant recevoir, le cas échéant, un habillage supplémentaire.The seal between the removable hearth 4 to be inserted and the vertical frame 2 is ensured by a single seal 5 attached to the vertical frame 2, or even fitted to said hearth 4, while the seal between the frame 2 and the open hearth of the existing chimney is ensured by the masonry pressing against the frame 2 (FIG. 2), this masonry being able to receive, if necessary, an additional covering.

Il est également possible de réaliser le jointoiement entre le cadre vertical 2 et le foyer ouvert de la cheminée existante au moyen de plaques thermiquement résistantes 18 (figure 3) s'appuyant, d'une part, contre les profilés formant le cadre 2, et d'autre part, contre un profilé 19 solidaire de la paroi verticale correspondante 20 de la cheminée existante, ces plaques 18 pouvant être en amiante-ciment, en fibro-ciment, en tôle, ou analogue.It is also possible to make the jointing between the vertical frame 2 and the open hearth of the existing chimney by means of thermally resistant plates 18 (FIG. 3) bearing, on the one hand, against the profiles forming the frame 2, and on the other hand, against a profile 19 integral with the corresponding vertical wall 20 of the existing chimney, these plates 18 may be asbestos-cement, fiber cement, sheet metal, or the like.

Conformément à une variante de réalisation de l'invention, non représentée aux dessins annexés, les glissières 1 peuvent être sous forme de rails de guidage en U coopérant avec des petits rouleaux effleurant légèrement sous la base du foyer amovible 4 à insérer. Un tel mode de réalisation permet de faciliter la manoeuvre du foyer amovible 4 lors de sa mise en place, ainsi que lors de son retrait, par exemple en vue d'un ramonage et d'un nettoyage, ou d'une autre visite d'entretien.According to an alternative embodiment of the invention, not shown in the accompanying drawings, the slides 1 may be in the form of U-shaped guide rails cooperating with small rollers lightly touching under the base of the removable hearth 4 to be inserted. Such an embodiment makes it easier to maneuver the removable hearth 4 when it is put in place, as well as when it is removed, for example for sweeping and cleaning, or for another visit. interview.

Il est également possible, suivant une autre variante de réalisation de l'invention, non représentée au dessin annexé, de munir le cadre 2 derrière chaque montant d'un double rail latéral, dont l'une des parties, est solidarisée avec le côté correspondant du foyer. Il est ainsi possible de dégager le foyer hors de son logement à la manière d'un tiroir, tout en assurant son maintien, par exemple dans le cas d'un foyer ouvert surélevé par rapport au sol environnant.It is also possible, according to another alternative embodiment of the invention, not shown in the accompanying drawing, to provide the frame 2 behind each upright a double side rail, one of the parts of which is secured to the corresponding side of the fireplace. It is thus possible to clear the hearth out of its housing in the manner of a drawer, while ensuring its maintenance, for example in the case of an open hearth raised relative to the surrounding ground.

Grâce à l'invention, il est possible de réaliser un foyer amovible à insérer dans une cheminée à feu ouvert existante pouvant, d'une part, être sorti facilement pour des visites périodiques de ramonage et de nettoyage et, d'autre part, être maintenu avec une étanchéité parfaite en position de service. En outre, aucun accessoire supplémentaire de finition, pour l'étanchéité ou le montage, n'est nécessaire.Thanks to the invention, it is possible to produce a removable hearth to be inserted into an existing open fire which can, on the one hand, be easily removed for periodic sweeping and cleaning visits and, on the other hand, be maintained with a perfect seal in the service position. In addition, no additional finishing accessories, for sealing or mounting, are required.

En outre, le foyer amovible conforme à l'inven- tion se présente sous forme d'un "insert sortant" pouvant être manoeuvré à la manière d'un tiroir, et est ainsi d'un accès facile, en particulier pour un remplacement de pièces défectueuses ou pour d'autres opérations d'entretien.In addition, the removable hearth according to the inven - tion is in the form of an "outgoing insert" operable in the manner of a drawer, and is thus easy access, particularly for a replacement defective parts or for other maintenance operations.

Du fait de cette facilité de démontage du foyer amovible 4, une utilisation du foyer existant peut facilement être envisagée avec maintien de l'habillage, par simple démontage des glissières 1 et des éléments obliques 8. Une telle utilisation de la cheminée existante peut notamment se concevoir pendant les périodes d'intersaison, où un chauffage à haut rendement n'est pas indispensable.Because of this ease of dismantling the removable hearth 4, use of the existing hearth can easily be envisaged with maintenance of the covering, by simple disassembly of the slides 1 and of the oblique elements 8. Such use of the existing chimney can in particular be design during off-season, when high-efficiency heating is not essential.

Enfin, du fait de la prévision d'un joint 5 écrasé entre le cadre vertical 2 et un agencement avant 3 du foyer amovible 4, le montage de ce dernier offre une sécurité parfaite du point de vue de l'étanchéité contre les fuites éventuelles de gaz.Finally, due to the provision of a seal 5 crushed between the vertical frame 2 and a front arrangement 3 of the removable hearth 4, the mounting of the latter offers perfect security from the point of view of sealing against possible leaks from gas.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté au dessin annexé. Des modifications restent possibles, notamment du point de vue de la constitution des différents 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 drawing. Modifications are still possible, especially from the point view of the constitution of the various elements, or by substitution of technical equivalents, without departing from the scope of protection of the invention.
