Description
L'invention est relative à un dispositif de compensation du levage de porte frontale d'insert de cheminées. Elle trouvera tout particulièrement son application chez les fabricants de matériels de chauffage.The invention relates to a device for compensating the lifting of the front door of a chimney insert. It will particularly find its application in the manufacturers of heating equipment.
Le chauffage direct par combustion dans un âtre de cheminée à foyer ouvert qui était jadis largement utilisé est très agréable sur le plan du spectacle de la flamme mais présente toutefois quelques inconvénients.Direct combustion heating in an open hearth fireplace which was once widely used is very pleasant in terms of the spectacle of the flame but has however some drawbacks.
Tout d'abord, il n'y a aucun contrôle du régime de chauffe étant donné que l'admission d'air est libre. Ensuite, le rendement de combustion est médiocre car une partie importante des calories est évacuée avec les gaz de combustion. Quelques progrès ont été accomplis en plaçant des récupérateurs de chaleur dans la hotte, cependant le fonctionnement des échangeurs dépend essentiellement du tirage. Si ce dernier est important, seulement une faible partie des calories peut être récupérée.First of all, there is no control of the heating regime since the air intake is free. Then, the combustion efficiency is poor because a significant part of the calories is evacuated with the combustion gases. Some progress has been made by placing heat recuperators in the hood, however the operation of the exchangers depends essentially on the draft. If the latter is important, only a small part of the calories can be recovered.
En ce qui concerne la fabrication des cheminées, il est nécessaire de respecter certains principes pour obtenir un fonctionnement satisfaisant. En particulier, les dimensions de l'ouverture de l'âtre doivent être établies en fonction des dimensions de la cheminée, ceci pour obtenir un tirage satisfaisant.Regarding the manufacture of fireplaces, it is necessary to respect certain principles to obtain satisfactory operation. In particular, the dimensions of the hearth opening must be established according to the dimensions of the chimney, this to obtain a satisfactory draft.
Chaque cas doit être traité individuellement et ce type de fabrication relève de l'artisanat. Pour donner satisfaction en toutes circonstances et permettre une fabrication industrielle, les constructeurs de matériels de chauffage ont proposé à leur clientèle la mise en place d'insert de cheminée. Il s'agit de matériels spécialement étudiés pour être placés dans l'âtre d'une cheminée existante ou être intégrés dans une construction nouvelle de cheminée. L'insert comprend un foyer, un système d'évacuation des fumées et généralement un dispositif de récupération des cendres de combustion. En outre, et c'est là son point fort, l'insert comporte une porte étanche frontale qui lui permet de fonctionner à foyer ouvert ou fermé. En fonctionnement à foyer ouvert, la porte est escamotée dans la hotte de la cheminée.Each case must be treated individually and this type of manufacturing is a craft. To give satisfaction in all circumstances and allow industrial manufacturing, the manufacturers of heating equipment offered their customers the installation of a chimney insert. These are materials specially designed to be placed in the hearth of an existing fireplace or be integrated into a new chimney construction. The insert includes a fireplace, a smoke evacuation system and generally a device for recovering combustion ash. In addition, and this is its strong point, the insert has a sealed front door which allows it to operate in open or closed hearth. In open hearth operation, the door is retracted into the chimney hood.
Cette possibilité de fonctionner à double régime de chauffe permet de bénéficier des avantages de chacun. Avec le foyer ouvert, on profite du spectacle de la flamme ; par contre, avec le régime de chauffe à foyer fermé, il est possible de contrôler parfaitement la combustion et d'obtenir un rendement de chauffage élevé.This possibility of operating with a double heating regime makes it possible to benefit from the advantages of each. With the fireplace open, you can enjoy the spectacle of the flame; on the other hand, with the closed hearth heating regime, it is possible to perfectly control the combustion and obtain a high heating efficiency.
Les caractéristiques calorifiques de l'insert sont calculées pour qu'il fonctionne correctement dans les deux cas de régime de chauffe et le choix des matériaux est établi pour offrir un produit de qualité. La clientèle peut également choisir le modèle de cheminée à construire autour de l'insert en fonction de ses goûts, la maçonnerie de la cheminée n'ayant qu'un rôle ornemental.The calorific characteristics of the insert are calculated so that it functions correctly in both cases of heating regime and the choice of materials is established to offer a quality product. Customers can also choose the model of fireplace to build around the insert according to their tastes, the masonry of the fireplace having only an ornamental role.
Il se pose parfois des problèmes de compatibilité entre cheminée et insert, en particulier au niveau de l'escamotage de la porte frontale sous la hotte. En effet, certaines caractéristiques dimensionnelles doivent être respectées pour permettre le relevage de la porte frontale sous la hotte, en particulier il faut que la hotte soit suffisamment largement dimensionnée pour recevoir la porte frontale et que le fronton placé au-dessus de l'ouverture de l'âtre soit suffisamment dégagé pour permettre le passage de la porte. Si tel n'est pas le cas, il faut utiliser un insert à porte ouvrante classique mais dans ce cas, le fonctionnement à foyer ouvert est moins esthétique. Ces types d'insert ne jouissent pas des faveurs du public qui préfère une porte frontale escamotable sous la hotte.There are sometimes problems of compatibility between the chimney and the insert, in particular at the level of the retraction of the front door under the hood. Indeed, certain dimensional characteristics must be respected to allow the front door to be raised under the hood, in particular it is necessary that the hood is sufficiently large enough to receive the front door and that the pediment placed above the opening of the hearth is sufficiently clear to allow the passage of the door. If not, use a door insert standard opening but in this case, the open hearth operation is less aesthetic. These types of inserts do not enjoy the favor of the public who prefer a retractable front door under the hood.
Le relevage des portes frontales est assuré au moyen de leviers articulés qui sont équipés de contrepoids de compensation. Ainsi, le levage de la porte est aisé. Pour que ce dispositif fonctionne, il faut bien entendu disposer d'un dégagement intérieur suffisant pour permettre la rotation des bras de leviers dans la hotte. Malheureusement, de nombreuses cheminées sont équipées d'un bandeau frontal ornemental disposé à l'aplomb de l'ouverture de l'âtre qui gêne la manoeuvre du bras de levier. Avec ce type de cheminée, le relevage de la porte frontale sous la hotte ne peut être envisagé.The front doors are raised by means of articulated levers which are fitted with compensating counterweights. Thus, the lifting of the door is easy. For this device to work, it is of course necessary to have sufficient internal clearance to allow the rotation of the lever arms in the hood. Unfortunately, many chimneys are equipped with an ornamental frontal strip arranged in line with the opening of the hearth which hinders the operation of the lever arm. With this type of chimney, the raising of the front door under the hood cannot be envisaged.
Le but principal de la présente invention est de présenter un dispositif de compensation de levage de porte frontale d'insert de cheminée qui soit compatible précisément avec les cheminées dotées d'un bandeau supérieur placé à l'aplomb de l'ouverture de l'âtre. Ce type de cheminées est très fréquent et en outre, cela permet de ne pas devoir encastrer totalement l'insert dans le creux de la cheminée. Avec le dispositif de compensation de la présente invention, l'insert peut être disposé à ras de l'âtre, ce qui est particulièrement appréciable sur le plan esthétique avec le fonctionnement à foyer ouvert. En effet, dans ce cas, la combustion est dégagée et la flamme est largement visible.The main object of the present invention is to present a device for compensating the lifting of the front door with a chimney insert which is compatible precisely with chimneys equipped with an upper strip placed directly above the opening of the hearth. . This type of chimney is very frequent and in addition, it allows not to have to completely embed the insert in the hollow of the chimney. With the compensation device of the present invention, the insert can be placed flush with the hearth, which is particularly appreciable from an aesthetic point of view with open hearth operation. Indeed, in this case, combustion is released and the flame is widely visible.
De plus, avec le dispositif de compensation de la présente invention, il n'est plus nécessaire de devoir construire une hotte surdimensionnée par rapport à la taille de l'insert afin que la hotte recouvre largement l'insert et en particulier que le bandeau frontal soit saillant par rapport à l'aplomb de la porte de l'insert.In addition, with the compensation device of the present invention, it is no longer necessary to have to build an oversized hood relative to the size of the insert so that the hood largely covers the insert and particular that the front strip protrudes from the plumb line of the insert door.
D'autres buts et avantages de la présente invention apparaîtront au cours de la description qui va suivre qui n'est donnée qu'à titre indicatif et qui n'a pas pour but de la limiter.Other objects and advantages of the present invention will appear during the description which follows which is given for information only and which is not intended to limit it.
Le dispositif de compensation du levage de porte frontale d'insert de cheminée, destiné en particulier à permettre l'escamotage sans effort de la porte dans la hotte de la cheminée à âtre, qui présente un bandeau supérieur placé à l'aplomb de l'ouverture de l'âtre est caractérisé par le fait qu'il comprend des moyens de déport en retrait de la porte durant son relevage.The device for compensating the lifting of the front door with a chimney insert, intended in particular to allow the effortless retraction of the door in the hood of the hearth chimney, which has an upper strip placed directly above the the hearth opening is characterized by the fact that it includes offset means which are set back from the door during its lifting.

L'invention vise un dispositif de compensation du levage de porte frontale d'insert de cheminée. Elle trouvera tout particulièrement son application chez les fabricants de matériels de chauffage domestique.The invention relates to a device for compensating the lifting of the front door of a chimney insert. It will particularly find its application in the manufacturers of domestic heating equipment.
Les cheminées à âtre dans les habitations modernes jouent généralement un double rôle, d'une part elles ont un but d'amélioration d'esthétique et d'autre part elles assurent une fonction de chauffage auxiliaire. La création de l'insert a permis d'être performant dans les deux domaines. La cheminée à âtre est conçue comme un habillage construit autour d'un insert qui lui est étudié pour être performant sur le plan de la combustion. L'insert peut également être introduit dans un âtre de cheminée existante pour faciliter son fonctionnement.Chimneys with hearths in modern dwellings generally play a double role, on the one hand they have an aim of improvement of esthetics and on the other hand they ensure an auxiliary heating function. The creation of the insert made it possible to be efficient in both areas. The hearth fireplace is designed as a cladding built around an insert which has been designed to be efficient in terms of combustion. The insert can also be inserted into an existing fireplace hearth to facilitate its operation.
L'insert est généralement équipé des différents dispositifs qui le rendent fonctionnel : cendrier à tiroir, régulation d'admission d'air, échangeur thermique ...The insert is generally equipped with the various devices which make it functional: ashtray with drawer, regulation of air intake, heat exchanger ...
En outre, l'insert peut fonctionner selon deux régimes de chauffe qui sont à foyer ouvert ou fermé. A foyer ouvert, les utilisateurs bénéficient du spectacle direct de la flamme, par contre à foyer fermé, il est possible de contrôler l'allure de chauffe. Pour fermer le foyer, les inserts sont généralement pourvus de porte frontale et la clientèle apprécie tout particulièrement les portes vitrées relevables pour être escamotées dans la hotte.In addition, the insert can operate according to two heating regimes which are open or closed. With an open hearth, users benefit from the direct spectacle of the flame, on the other hand, with a closed hearth, it is possible to control the heating rate. To close the fireplace, the inserts are generally fitted with a front door and customers particularly appreciate the liftable glass doors to be retracted into the hood.
Cette construction est actuellement possible dans la mesure où la cheminée à âtre ne présente pas un bandeau frontal placé à l'aplomb de la porte à relever, ceci afin que le mécanisme de compensation du relevage puisse disposer d'un dégagement nécessaire. Malheureusement cette contrainte freine le développement commercial de ce type d'insert. La présente invention se propose de lever cet inconvénient.This construction is currently possible insofar as the hearth chimney does not have a frontal strip placed at the base of the door to be lifted, this so that the mechanism for compensating the lift can have a necessary clearance. Unfortunately this constraint slows the commercial development of this type of insert. The present invention proposes to overcome this drawback.
La figure 1 représente une cheminée (1) équipée d'un insert (2) placé dans son âtre. La cheminée (1) comporte une hotte (3) supérieure qui masque le conduit d'évacuation des fumées. L'insert comprend une porte frontale (4) susceptible d'être relevée et escamotée dans la hotte (3). Il s'agit d'une construction traditionnelle à la portée de l'Homme de l'Art. Toutefois, cette mise en oeuvre n'est actuellement possible que si la cheminée (1) comprend un bandeau supérieur (5) suffisamment dégagé de l'aplomb de la porte frontale (4) pour que celle-ci puisse être soulevée par un dispositif de compensation traditionnel tel qu'illustré à la figure 2.Figure 1 shows a fireplace (1) equipped with an insert (2) placed in its hearth. The chimney (1) includes an upper hood (3) which masks the smoke evacuation duct. The insert includes a front door (4) capable of being raised and retracted into the hood (3). It is a traditional construction within the reach of the skilled person. However, this implementation is currently only possible if the chimney (1) comprises an upper strip (5) sufficiently clear of the plumb of the front door (4) so that it can be lifted by a device for traditional compensation as illustrated in Figure 2.
En effet, la porte frontale (4) est épaisse et la manoeuvre de relevage doit être assistée par un dispositif de compensation formé d'un bras de levier (6) articulé à la partie supérieure de l'insert (2) autour d'un axe (7), un contrepoids (8) ou autre moyen de poussée agit sur l'extrémité du bras (6) pour contrebalancer le poids de la porte (4) articulée à l'autre extrémité du bras (6).Indeed, the front door (4) is thick and the lifting operation must be assisted by a compensation device formed by a lever arm (6) articulated at the upper part of the insert (2) around a axis (7), a counterweight (8) or other pushing means acts on the end of the arm (6) to counterbalance the weight of the door (4) articulated at the other end of the arm (6).
Ce dispositif traditionnel de compensation du levage de la porte (4) nécessite un dégagement suffisant dans la partie supérieure de l'insert pour autoriser la rotation du bras (6). Comme cela est visible à la figure 2, la présence du bandeau supérieur (5) constitue une gêne à la rotation du bras (6). Il est nécessaire de s'assurer de la compatibilité de l'esthétique de la cheminée (1) avec les caractéristiques dimensionnelles de l'insert (2) pour permettre la mise en place de celui-ci dans l'âtre de la cheminée. Or, bon nombre de cheminées présentent un bandeau supérieur (5) placé sensiblement à l'aplomb de la porte (4).This traditional device for compensating the lifting of the door (4) requires sufficient clearance in the upper part of the insert to allow rotation of the arm (6). As can be seen in FIG. 2, the presence of the upper strip (5) constitutes a hindrance to the rotation of the arm (6). It is necessary to ensure that the aesthetics of the chimney (1) are compatible with the dimensional characteristics of the insert (2) to allow it to be placed in the hearth of the chimney. However, many chimneys have an upper strip (5) placed substantially in line with the door (4).
Selon la caractéristique principale de la présente invention, le dispositif de compensation de levage proposé comprend des moyens de déport en retrait de la porte (4) durant son relevage.According to the main characteristic of the present invention, the proposed lifting compensation device comprises offset means set back from the door (4) during its lifting.
Cette manoeuvre en retrait de la porte permet de la disposer sous le bandeau supérieur de l'âtre de la cheminée sans que celui-ci constitue une gêne pour le relevage. La compatibilité est donc assurée.This maneuver behind the door allows it to be placed under the upper strip of the hearth of the fireplace without it being a hindrance for lifting. Compatibility is therefore ensured.
La figure 3 schématise l'insert (2) dont la porte frontale (4) est placée sous le bandeau supérieur (5) de l'âtre de cheminée.Figure 3 shows schematically the insert (2) whose front door (4) is placed under the upper strip (5) of the fireplace hearth.
Pour effectuer le relevage de la porte (4) dans le volume intérieur (9) placé sous la hotte, tel qu'illustré à la figure 4, on commence par incliner la porte (4) de telle sorte que celle-ci puisse pénétrer dans l'espace (10) laissé entre l'insert (2) et le bandeau supérieur (5) de la cheminée.To carry out the lifting of the door (4) in the interior volume (9) placed under the hood, as illustrated in Figure 4, we begin by tilting the door (4) so that it can penetrate into the space (10) left between the insert (2) and the upper strip (5) of the chimney.
Cette opération étant réalisée, on amorce le mouvement de remontée de la porte (4) tel qu'illustré à la figure 5, ce qui provoque un raccourcissement du bras de levier (6). Ceci permet à la porte (4) de glisser dans l'espace (10) grâce à un déport en retrait de la porte (4) par rapport au bandeau supérieur (5).This operation being carried out, the upward movement of the door (4) is started as illustrated in FIG. 5, which causes a shortening of the lever arm (6). This allows the door (4) to slide in the space (10) thanks to an offset retraction of the door (4) relative to the upper strip (5).
Il faut souligner que ce raccourcissement du bras de levier (6) favorise le relevage de la porte (4) étant donné que la compensation fournie par le contrepoids (8) est accentuée dans ce cas.It should be noted that this shortening of the lever arm (6) promotes the lifting of the door (4) since the compensation provided by the counterweight (8) is accentuated in this case.
La figure 6 schématise la dernière phase du relevage de la porte (4) selon laquelle la porte est entièrement escamotée sous la hotte. Le levier (6) présente une longueur artificiellement réduite ce qui a permis de réduire le rayon d'encombrement nécessaire au relevage de la porte (4).Figure 6 shows schematically the last phase of lifting the door (4) according to which the door is fully retracted under the hood. The lever (6) has a artificially reduced length which has made it possible to reduce the overall radius necessary for lifting the door (4).
Pour réabaisser la porte (4), l'ensemble des opérations est à nouveau effectué en sens contraire. Cela signifie que lorsque la porte (4) est abaissée et placée en face du foyer de l'insert (2), le levier (6) se voit artificiellement rallongé pour permettre à ladite porte (4) de s'appliquer contre la face avant de l'insert (2).To lower the door (4), all operations are again carried out in the opposite direction. This means that when the door (4) is lowered and placed opposite the focal point of the insert (2), the lever (6) is artificially extended to allow said door (4) to be pressed against the front face insert (2).
La réalisation des moyens de déport en retrait de la porte (4) durant son relevage peut prendre plusieurs formes. Il s'agit, bien que le levier (6) présente une géométrie fixe, de permettre la modification de la longueur du bras de levier correspondant afin de modifier la distance séparant l'axe de rotation (7) du levier (6) de la porte (4) au cours de la manoeuvre.The realization of the offset means behind the door (4) during its lifting can take several forms. This is, although the lever (6) has a fixed geometry, to allow the modification of the length of the corresponding lever arm in order to modify the distance separating the axis of rotation (7) of the lever (6) from the door (4) during the maneuver.
La figure 7 illustre un premier mode de réalisation des moyens de déport en retrait de la porte (4) au cours de son relevage. Il s'agit d'une chape (11) à double articulation, fixée d'une part à l'extrémité du levier (6) autour d'un axe (12) et d'autre part à la partie supérieure de la porte (4) autour d'un axe d'articulation (13). Lors du relevage de la porte (4), de par son propre poids la porte (4) a tendance à faire pivoter la chape (11) autour de l'axe (12) de telle sorte que la chape vienne se placer transversalement au levier (6). Le déplacement angulaire correspondant a tendance à rapprocher la porte (4) de l'axe de rotation (7) et par voie de conséquence provoque un déport en retrait de la porte.FIG. 7 illustrates a first embodiment of the offset means set back from the door (4) during its lifting. It is a yoke (11) with double articulation, fixed on the one hand to the end of the lever (6) around an axis (12) and on the other hand to the upper part of the door ( 4) around an axis of articulation (13). During the lifting of the door (4), by its own weight the door (4) tends to rotate the yoke (11) around the axis (12) so that the yoke comes to be placed transversely to the lever (6). The corresponding angular movement tends to bring the door (4) closer to the axis of rotation (7) and consequently causes a backward offset of the door.
L'axe d'articulation (13) permet d'incliner la porte (4) de telle sorte que celle-ci puisse être orientée durant son relevage.The hinge pin (13) allows the door (4) to be tilted so that it can be oriented during its lifting.
Une butée (14) est fixée à l'extrémité du levier (6) afin de limiter le débattement angulaire de la chape (11). Il faut en effet éviter que celle-ci ne puisse pivoter au-delà d'une certaine limite ce qui aurait pour conséquence de provoquer un coincement de la chape (11) durant l'abaissement de la porte (4). En aucun cas, la chape (11) ne doit avoir tendance à se replier pour se placer côte à côte avec le levier (6) mais au contraire, la chape (11) doit se replacer dans le prolongement du levier (6) en cas d'abaissement de la porte (4).A stop (14) is fixed to the end of the lever (6) in order to limit the angular movement of the yoke (11). It must in fact be avoided that the latter cannot pivot beyond a certain limit, which would have the consequence of causing jamming of the yoke (11) during the lowering of the door (4). In any case, the yoke (11) must not have a tendency to fold back to be placed side by side with the lever (6) but on the contrary, the yoke (11) must be replaced in the extension of the lever (6) in case lowering the door (4).
La figure 8 schématise un second mode de réalisation des moyens de déport en retrait de la porte (4) durant son relevage. Selon cette conception, les moyens se présentent sous la forme d'une pièce de liaison coudée (15) fixée à la partie supérieure de la porte (4) et articulée à l'extrémité du levier (6) autour d'un point de liaison (16) mobile en translation le long dudit levier (6). Cette mobilité en translation de l'axe de rotation (16) permet de rapprocher la porte (4) de l'axe de rotation (7) durant la manoeuvre de relevage de ladite porte (4).Figure 8 shows schematically a second embodiment of the offset means set back from the door (4) during its lifting. According to this design, the means are in the form of a bent connecting piece (15) fixed to the upper part of the door (4) and articulated at the end of the lever (6) around a connection point (16) movable in translation along said lever (6). This translational mobility of the axis of rotation (16) allows the door (4) to be brought closer to the axis of rotation (7) during the lifting operation of said door (4).
Le point de liaison (16) mobile peut être par exemple formé d'une axe solidaire de la pièce coudée (15) qui traverse le levier (6) dans un trou (17) oblong. De la sorte, l'axe (16) peut se déplacer transversalement le long de l'extrémité du levier (6).The movable connection point (16) can for example be formed by an axis integral with the bent piece (15) which passes through the lever (6) in an oblong hole (17). In this way, the axis (16) can move transversely along the end of the lever (6).
D'autres mises en oeuvre de la présente invention, à la portée de l'Homme de l'Art, pourraient également être envisagées sans pour autant sortir du cadre de celle-ci.Other implementations of the present invention, within the reach of ordinary skill in the art, could also be envisaged without departing from the scope thereof.
