Abstract

When the fire (17) is in its raised position, the grate (1) is raised on its scissors linkage (10) and the lid (4) is pivoted about its rear edge by a linkage (12), so that it stands up vertically against a wide flat flue, which forms the back of the fire. A hood (7) with a damper (8) catches the smoke from the fire. When the fire is lowered the grate sinks to the bottom of a space (2) surrounded by walls (13) and the lid shuts. Down over the aperture at the top of the space. The smoke from the fire rises up through the flue and the fire is hidden from view.

Description

La présente invention concerne une cheminée à foyer ouvert dont la plaque foyère descend dans un bac fermé simultanément , ou non, automatisé, ou non, par plaque décorative de fond de foyer. The present invention relates to an open hearth fireplace whose hearth plate descends into a closed container simultaneously, or not, automated or not, by decorative plate at the bottom of the hearth.

Les cheminées à foyer ouvert sont connues pour être dangereuses sans une surveillance accrue. Des bûches en combustion peuvent tomber de la plaque foyère provoquant des incendies. Leur fonction d'appareil de chauffage est souvent diminuée par ce risque important . Pour remédier à cet inconvénient, certains constructeurs réalisent des foyers fermés par des vitres réfractaires amovibles au dessus foyer. Ces ensembles peu esthétiques sont habillés par des briques, de la pierre tout autres matériaux. Open fireplaces are known to be dangerous without increased supervision. Burning logs may fall from the fire top causing fires. Their function as a heater is often diminished by this significant risk. To overcome this drawback, some manufacturers produce fireplaces closed by removable refractory panes above the firebox. These unattractive sets are dressed in bricks, stone and all other materials.

Les sensations du feu sont occultées par cette barrière de verre, et de matériaux opaques. The sensations of fire are obscured by this barrier of glass and opaque materials.

Le rendement et la sécurité d'utilisation sont par ailleurs augmentés. The efficiency and safety of use are also increased.

On connaît notamment par le FRA 2 597 197 un récipient de combustion du type cheminée qui comporte deux niveaux de foyers : un foyer inférieur fermé, obturé à sa partie supérieure par deux volets susceptibles de se déplacer l'un par rapport à l'autre, et un foyer supérieur ouvert dont le fond est constitué par ces volets qui forment la base de ce foyer supérieur. FRA 2 597 197 discloses in particular a chimney type combustion container which has two levels of hearths: a closed lower hearth, closed at its upper part by two flaps capable of moving relative to each other, and an open upper hearth, the bottom of which is formed by these shutters which form the base of this upper hearth.

Dans ce type d'appareils, l'utilisateur est dans l'obligation de déplacer les bûches en combustion afin d'attraper à l'aide d'un outil la clef d'ouverture de ces volets. La translation du volet risque d'entraîner les bûches en dehors de la cheminée au risque de provoquer de graves brûlures et de générer un incendie à l'habitation. In this type of appliance, the user is obliged to move the burning logs in order to catch the opening key of these shutters using a tool. The translation of the shutter may entail the logs outside the chimney at the risk of causing serious burns and generating a fire in the home.

La chute du combustible dans le récipient de combustion après l'ouverture volets provoque un nuage de cendres dans l'habitation. The fall of the fuel in the combustion vessel after opening the shutters causes an ash cloud in the dwelling.

La présente invention a pour but d'éviter les inconvénients d'insécurité lors de la manipulation et lors du fonctionnement en cas d'absence, tout en conservant la sensation réelle d'une "flambée d'hiver"et le rendement d'un chauffage à foyer fermé. A cet effet, l'invention a donc pour objet principal un dispositif de montee et de descente de la plaque foyère à l'intérieur d'un bac en acier réfractaire refermé simultanément ou non par la plaque décorative de fond de foyer. The object of the present invention is to avoid the drawbacks of insecurity during handling and during operation in the event of absence, while retaining the real feeling of a "winter outbreak" and the efficiency of heating. with closed hearth. To this end, the main object of the invention is therefore a device for raising and lowering the hearth plate inside a refractory steel tank closed simultaneously or not by the decorative plate at the bottom of the hearth.

On obtient donc un foyer ouvert lorsque la plaque foyère est en position haute et la plaque décorative de fond de foyer en position verticale ouverte et un foyer fermé équipé de son conduit d'évacuation des fumées indépendant lorsque la plaque foyère est en position basse et la plaque décorative de fond de foyer en position horizontale fermée. Selon une autre caractéristique, la montée et la descente de la plaque foyère est commandée ou télécommandée par un mécanisme de tringlerie de ressorts, motorisé manuel, entraînant simultanément ou non la fermeture, l'ouverture partielle, l'ouverture total de son capot constitué par la plaque fond de foyer décorative permettant entre autre de régler l'apport d'air nécessaire à combustion. En particulier, le mécanisme de tringlerie peut être motorisé à l'aide d'un vérin électrique commandé manuellement ou par télécommande ou par vis et une manivelle entraînée par futilisteur. An open hearth is therefore obtained when the hearth plate is in the high position and the decorative bottom plate of the hearth in the open vertical position and a closed hearth equipped with its independent smoke evacuation duct when the hearth plate is in the low position and the decorative bottom plate in closed horizontal position. According to another characteristic, the ascent and descent of the hearth plate is controlled or remote controlled by a spring linkage mechanism, manual motorized, causing simultaneous or not the closing, the partial opening, the total opening of its cover constituted by the decorative bottom plate allowing, among other things, to regulate the air supply necessary for combustion. In particular, the linkage mechanism can be motorized using an electric actuator controlled manually or by remote control or by screw and a crank driven by a futilist.

En outre, tringlerie entraîne, par son déplacement nécessaire à montée de la plaque foyere, l'ouverture ou non, du capot supérieur constitué de la plaque décorative de fond de foyer dont le poids est en partie compensé par un ressort de rappel. In addition, linkage causes, by its movement necessary for mounting the hearth plate, the opening or not, of the upper cover consisting of the decorative plate at the bottom of the hearth, the weight of which is partly offset by a return spring.

Selon autre caractéristique, la tringlerie extérieure entraîne une tringlerie dite en "ciseau"disposé dans le bac, sous la plaque foyère, démultipliant le déplacement nécessaire ' sa montée. According to another characteristic, the external linkage causes a so-called "chisel" linkage arranged in the tank, under the hearth plate, increasing the displacement necessary for its rise.

Selon encore d'autres caractéristiques en position basse le foyer fermé dispose de son propre moyen d'évacuation des fumées par un conduit indépendant disposant de son propre reglage et en position haute, en foyer ouvert, une autre évacuation réglable indépendamment. Les deux sorties convergent vers un même conduit en toiture. According to still other characteristics in the low position, the closed hearth has its own means of evacuating the fumes by an independent duct having its own adjustment and in the high position, in the open hearth, another evacuation which is independently adjustable. The two outlets converge on the same roof duct.

Selon une dernière caractéristique, un vide d'air nécessaire à une convection naturelle ou forcée aménagé autour du bac et du conduit d'évacuation des fumées par une enveloppe métallique soudée hermétiquement autour de celui-ci et équipé de trous d'introduction d'air neuf et de soufflage d'air chaud en position supérieure. According to a last characteristic, an air vacuum necessary for natural or forced convection arranged around the tank and the smoke evacuation duct by a metal envelope welded hermetically around it and equipped with air introduction holes new and hot air blower in the upper position.
