Abstract

The invention relates to open hearths, closed hearths and heat-recovery hearths, and makes it possible to eliminate the disadvantages of thermal shocks giving rise to the breaking or cracking of the hearth cores and plates of fireplaces or to the separation of the bricks. It comprises a concealed steel reinforcement 1, to which metal profiles 3 have been fixed, into which grooved refractory bricks 2 slide, which are not integral with one another, which makes it possible to absorb the expansion and the stresses of the materials utilised. It comprises moreover a heat recuperator consisting of a steel box 7, inside which the passage of the air is carried out by natural or forced convection. This invention can be utilised with or without fire walls 2, it can be converted into a closed hearth by virtue of the element 4 equipped with a glazed door. The height of the hearth is variable by addition of the element 1. It also comprises an ash pan.

Description

La présente invention concerne les Foyers à feux ouverts, les foyers à feux fermés et les Foyers à récupération de chaleur,et permet de supprimer les inconvénients des chocs thermiques amenant à la cassure ou à la félure des coeurs et pla quels foyères de cheminées ou au décollement des briques. The present invention relates to Fireplaces with open fires, fireplaces with closed fires and Fireplaces with heat recovery, and makes it possible to eliminate the drawbacks of thermal shocks leading to breakage or felting of hearts and pla which fireplaces or peeling off the bricks.

Danses dispositifs de ce genre, les joints sont en ciment réfractaire ainsi que leur assemblage donc d'un bloc homogène,qui subit toutes les contraintes et les dilata-tions de tous les différents materiaux qui les composent.~
Ce qui amène les félures et les cassures ou décollements des éléments. Ils sont également d'un poids très important.Dances such devices, the joints are refractory cement and their assembly therefore a homogeneous block, which undergoes all the stresses and dilations-tions of all the different materials that compose them. ~
Which brings felines and breaks or detachments of the elements. They are also very important.

D'autres dispositifs sont connus et comportent une plaque métallique ou de fonte qui ne favorise pas l'esthétique de la cheminée, et a le désavantage de refroidir beaucoup plus vite que les briques réfractaires. Other devices are known and include a metal or cast iron plate which does not promote the aesthetics of the chimney, and has the disadvantage of cooling much faster than refractory bricks.

Le foyer selon l'invention permet d'éviter tous ces inconvénients.Il est en effet composé d'une armature acier non visible(1) sur laquelle sont fixés des profilés metalliques(3)dans lesquels viennent se glisser des briquss réfractaires rainurées(2) non solidaires les unes des autres.Le jeu tant en largeur qu'en profondeur des rainures des briques réfractaires,et leur non solidarité entres elles permet d'absorber la dilatation et les contraintes des matériaux et supprime les risques de félure et de cassure. The fireplace according to the invention makes it possible to avoid all these drawbacks. It is in fact composed of a non-visible steel frame (1) on which are fixed metal profiles (3) in which grooved refractory bricks (2 ) not integral with one another. The play both in width and in depth of the grooves of the refractory bricks, and their non-solidarity between them makes it possible to absorb the expansion and the stresses of the materials and eliminates the risks of tearing and breaking.

La présente invention ne comporte aucun liant tel que béton,sable ciment etc... The present invention does not include any binder such as concrete, sand cement, etc.

La présente invention comporte un dispositif de récupération de chaleur composé d'un caisson acier solidaire des éléments de la figure 3.Ce caisson est mentionné sous -référence 7.Le passage de l'air peut se faire par convection naturelle ou forcée. The present invention comprises a heat recovery device composed of a steel box integral with the elements of FIG. 3. This box is mentioned under sub-reference 7. The air can be passed by natural or forced convection.

Cette invention peut être utilisée sans contre coeurs. This invention can be used without heart.

(fig 3)
Dans une première variante l'invention peut etre utilisée avec un ou deux contre-coeurs(fig 2)de msme conception que l'élément de base.(fig 3). (fig 3)
In a first variant, the invention can be used with one or two cores (fig 2) of the same design as the basic element (fig 3).

Dans une deuxième variante 1 invention peut étre transformée en foyer fermé grâce à l1élément fig 4 muni d'une porte vitrée, qui vient se fixer sur les deux contre coeurs, fig 2. In a second variant, 1 invention can be transformed into a closed hearth thanks to the element fig 4 provided with a glass door, which is fixed on the two counter-hearts, fig 2.

Dans chacune des variantes la hauteur du foyer peut être modifiée par adjonction d'éléments de mêmes conception que l'élément de base(fig 3).Cst élément est représenté par la figure 1. In each variant, the height of the hearth can be modified by adding elements of the same design as the basic element (fig 3). This element is shown in Figure 1.

La présents invention dans chacune de ses variantes comporte un cendrier. The present invention in each of its variants comprises an ashtray.

La présente invention permet un assemblage facile des différents éléments de par leur conception et leur poids sans connaissances techniques spéciales. The present invention allows easy assembly of the different elements by design and weight without special technical knowledge.

Claims
