Description

Cheminée équipée d'un foyer ouvert et fermable par une porte escamotable verticalement et relevable à l'horizontale. Fireplace equipped with an open fireplace that can be closed by a vertically retractable door that can be lifted horizontally.

L'invention a pour objet une cheminée équipée d'un foyer ouvert et fermable par 'une porte escamotable verticalement et relevable à l'horizontale, constituée autour d'un atre de jambages latéraux, portant un chambranle surmonté d'une hotte. The subject of the invention is a fireplace equipped with an open hearth which can be closed by 'a vertically retractable door which can be lifted horizontally, constituted around a space with side jambs, carrying a frame surmounted by a hood.

Il existe déjà de nombreuses cheminées équipées d'un foyer ouvert et fermable par une porte. Généralement cette porte montée sur des gongs verticaux s'ouvre dans un plan horizontal, voir la demande de brevet
BRISACH déposée en France le 8 Octobre 1982 sour le NO 82 17034. D'autres brevets décrivent des portes escamotables verticalement,voir la demande de brevet FR 81 17716/25 12932 , déposée le 14 Septembre 1981.There are already many fireplaces with an open hearth that can be closed by a door. Generally this door mounted on vertical gongs opens in a horizontal plane, see patent application
BRISACH filed in France on October 8, 1982 under NO 82 17034. Other patents describe vertically retractable doors, see patent application FR 81 17716/25 12932, filed on September 14, 1981.

Ces portes présentent quelques inconvénients. Les portes à ouverture dans un plan horizontal, nécessitent un grand espace de dégagement et gênent lorsque l'on veut utiliser la cheminée porte ouverte. These doors have some drawbacks. Doors opening in a horizontal plane, require a large clearance and interfere when you want to use the fireplace with the door open.

Les portes escamotables actuellement utilisées, doivent être souvent nettoyées, car les parois généralement vitrées et surtout la paroi interne s'obscurssissent en se recouvrant de suie, de particules de poussière, de goudron etc... The retractable doors currently used, must be often cleaned, because the generally glazed walls and especially the internal wall are obscured by being covered with soot, dust particles, tar etc ...

Les moyens pour escamoter les portes de cheminées ne permettent que partiellement de nettoyer la paroi interne vitrée. Les portes escamotables actuelles comme la porte décrite dans la demande de brevet FR. 81 17716/25 12932, ne peuvent être dégager suffisamment vers l'extérieure pour que la paroi interne soit complètement nettoyée et ce, même s'il existe des moyens plus ou moins efficaces pour éviter ou réduire le dépôt de suie sur ladite paroi. The means for retracting the fireplace doors only partially allow the internal glazed wall to be cleaned. Current retractable doors like the door described in the patent application FR. 81 17716/25 12932, cannot be released sufficiently to the outside so that the internal wall is completely cleaned, even if there are more or less effective means to avoid or reduce the deposit of soot on said wall.

Les portes escamotables actuelles sont d'un mécanisme complexe, bruyant et peu fiable par rapport à la durée de vie d'une cheminée. Current retractable doors are a complex mechanism, noisy and unreliable compared to the life of a fireplace.

L'invention évite tous ces inconvénients. The invention avoids all these drawbacks.

Elle permet d'obtenir une porte vitrée ou non, escamotable, qui peut être complètement dégagée de son axe de rotation qui fait charnière pour être relevée horizontalement et permettre ainsi le nettoyage complet de la paroi interne de ladite porte. It makes it possible to obtain a retractable glazed door or not, which can be completely disengaged from its axis of rotation which forms a hinge to be raised horizontally and thus allow complete cleaning of the internal wall of said door.

Le fonctionnement de la porte escamotable est très simple, fiable, et silencieux. The operation of the retractable door is very simple, reliable, and silent.

A cet effet, la porte selon l'invention est montée sur un cadre, et les moyens qui font office de glissières, sont disposés dans le prolongement supérieur des montants verticaux du dormant, où ils forment un châssis supérieur, la porte est suspendue à un moyen faisant office d'attache souple tels qu'une chaine ou un cabrez , s un contrepoids assure l'équilibre du mouvement de montée et de descente de la porte. L'attache est fixée à la partie supérieure du cadre de la porte, par des moyens qui font charnières, tels que des anneaux, de manière à permettre de pouvoir dégager la porte complètement et la positionner en position horizontale, pour permettre le nettoyage complet de la paroi interne. To this end, the door according to the invention is mounted on a frame, and the means which act as slides, are arranged in the upper extension of the vertical uprights of the frame, where they form an upper frame, the door is suspended from a means acting as a flexible attachment such as a chain or a ratchet, s a counterweight ensures the balance of the up and down movement of the door. The fastener is fixed to the upper part of the door frame, by means of hinges, such as rings, so as to be able to disengage the door completely and position it in a horizontal position, to allow complete cleaning of the inner wall.

Le ou les contrepoids reliés à l'attache sont disposés soit latéralement sur les cotés de la cheminée ou foyer, soit au-dessus le la hotte. Ils peuvent consister en de simples poids qui coulissent le long d'axes verticaux ou en un cylindre horizontal, ou par mouflage, les cables où les chalnes s'enroulent. The counterweight (s) connected to the fastener are arranged either laterally on the sides of the chimney or hearth, or above the hood. They can consist of simple weights which slide along vertical axes or in a horizontal cylinder, or by hauling, the cables where the chalnes are wound up.

Les figures ci-jointes données à titre d'exemple indicatif et non limitatif, permettront aisément de comprendre l'invention. The attached figures given by way of indicative and non-limiting example, will easily make it possible to understand the invention.

Elles représentent deux modes de réalisation préférés selon l'invention. They represent two preferred embodiments according to the invention.

La figure 1 est une vue en perspective de la cheminée avec sa porte escamotable, suspendue avec un moyen faisant office de contrepoids. Figure 1 is a perspective view of the fireplace with its retractable door, suspended with a means acting as a counterweight.

La figure 2 est une vue en perspective de la cheminée avec sa porte escamotable, en position escamotée, porte du foyer ouverte. Figure 2 is a perspective view of the fireplace with its retractable door, in the retracted position, door of the fireplace open.

La figure 3 est une vue en perspective de la cheminée avec sa porte escamotable, en position relevée horizontalement. Figure 3 is a perspective view of the chimney with its retractable door, in the horizontally raised position.

Dans la figure 1, la cheminée déposable ou foyer fermé 1 est composé de trois cotés 2, 3, 4 et d'une porte vitrée 5. Cette porte vitrée 5 est composée d'un cadre 6 qui entoure un verre 7. Le cadre 6 est monté sur un châssis 8, dont les montants verticaux 9 et 10 font office de glissières et se prolongent dans leur partie supérieure pour former un châssis supérieur 11 avec des glissières 9 A et 10 A, qui permettent à la porte vitrée 5 de s'escamoter en montant le long de ces glissières 9, 9A et 10, 10 A. In Figure 1, the removable fireplace or closed hearth 1 is composed of three sides 2, 3, 4 and a glass door 5. This glass door 5 is composed of a frame 6 which surrounds a glass 7. The frame 6 is mounted on a frame 8, whose vertical uprights 9 and 10 act as slides and extend in their upper part to form an upper frame 11 with slides 9 A and 10 A, which allow the glass door 5 to retract by climbing along these slides 9, 9A and 10, 10 A.

Ladite porte vitrée 5 est suspendue à une ou des attaches souples. Said glass door 5 is suspended from one or more flexible fasteners.

Les attaches souples peuvent être des câbles ou des chaînes 12, comme représentés dans la figure 1.The flexible fasteners can be cables or chains 12, as shown in FIG. 1.

Lesdites chaînes 12 sont reliées sur le cadre supérieur 13 de la porte vitrée 5, par des anneaux 14 et 15, et fixées à un point haut 16, 17 du châssis supérieur. Un contrepoids 18 , en forme de rouleau facilite les mouvements de montée et de descente de la porte vitrée 5, en réduisant l'effort à fournir, lesdites chaînes 12 étant mouflées sur ledit rouleau qui fait contrepoids 18. Said chains 12 are connected to the upper frame 13 of the glass door 5, by rings 14 and 15, and fixed to a high point 16, 17 of the upper frame. A counterweight 18, in the form of a roller, facilitates the upward and downward movements of the glass door 5, by reducing the effort to be provided, said chains 12 being mouflaged on said roller which forms a counterweight 18.

Les chaînes 12 auxquelles est suspendue la porte vitrée 5, font un demi- tour sur des poulies 19 et 20, montées sur un axe 21 dans la partie la plus haute du châssis supérieur 11, puis les chaînes 12 font un autre demi- tour sur le rouleau qui fait office de contrepoids 18, puis l'extrémité de chaque chaîne est arrimée à un point haut 16, 17 du châssis supérieur 11. The chains 12 to which the glass door 5 is suspended, make a U-turn on pulleys 19 and 20, mounted on an axis 21 in the highest part of the upper frame 11, then the chains 12 make another U-turn on the roller which acts as a counterweight 18, then the end of each chain is secured to a high point 16, 17 of the upper chassis 11.

Les figures 2 et 3 mettent en évidence un autre moyen pour réduire l'effort de manoeuvre de la porte vitrée 5. Ladite porte vitrée 5 est toujours suspendue à des chaînes 12, par des anneaux 14, 15, mais c'est l'extrémité desdites chaînes qui est directement reliée à des contrepoids 22, qui sont montés sur des axes verticaux 23 et 24, disposés sur les côtés 2 et 4 du foyer 1, comme on peut le voir aisément dans la figure 3, du fait de la rotation complète des chaînes 12, autour des anneaux 14 et 15, auxquels est suspendue la porte vitrée 5, et, celle-ci étant complètement dégagée de sa charnière il est possible de la relever horizontalement, pour nettoyer complètement la paroi interne en verre 7. Figures 2 and 3 highlight another way to reduce the operating force of the glass door 5. Said glass door 5 is still suspended from chains 12, by rings 14, 15, but it is the end said chains which is directly connected to counterweights 22, which are mounted on vertical axes 23 and 24, arranged on the sides 2 and 4 of the hearth 1, as can be easily seen in Figure 3, due to the complete rotation chains 12, around the rings 14 and 15, from which the glass door 5 is suspended, and, this being completely disengaged from its hinge, it is possible to raise it horizontally, to completely clean the internal glass wall 7.

La simplicité des moyens utilisés, assurent une grande fiabilité à l'ensemble du mécanisme et de plus, ce mécanisme peut être actionné sans bruit. The simplicity of the means used, ensure high reliability of the entire mechanism and moreover, this mechanism can be actuated without noise.
