Abstract

1. Chimney cowl, formed of an assembly of sheet-metal elements, comprising an annular, vertical-axis fitting (8; 26) which, with one or more top elements (9; 28) and one or more bottom elements (10, 11; 23), delimits passages situated at two different levels, characterized in that the fitting (8; 26) is an element in the shape of a frustum of pyramid which is connected to several bottom elements, in that the latter (10, 11; 23) are tubular-shaped, having parallel axes, and in that the said frustum of pyramid (8; 26) is divided into separate sections by one or more partition elements (12, 13; 24), each section corresponding to a bottom element, and each partition element (12, 13; 26) meeting two opposite walls of the fitting (8; 26) over the entire height between the said levels of the passages so as to prevent any communication between two tubular bottom elements over the height situated between the said levels.

Description

La présente invention a pour objet une cape de cheminée, formée d'un ensemble d'éléments en tôle métallique, comportant une garniture de forme annulaire d'axe vertical qui délimite avec un ou plusieurs éléments supérieurs et un ou plusieurs éléments inférieurs des passages situés à deux niveaux différents.The subject of the present invention is a chimney cap, formed of a set of sheet metal elements, comprising an annular lining of vertical axis which delimits, with one or more upper elements and one or more lower elements, from the passages located at two different levels.

On sait qu'il est avantageux de garnir les cheminées de capes de ce genre capables de prévenir la pénétration de la pluie dans la cheminée et assurant le tirage indépendamment de la direction du vent. Ainsi par exemple, l'exposé de brevet suisse CH-492 933 décrit une cape qui comporte plusieurs garnitures extérieures de forme fuselée qui s'engagent l'une dans l'autre de manière à délimiter avec un obturateur supérieur et un élément inférieur qui prolonge le conduit de fumée des paires de passages annulaires superposés.We know that it is advantageous to line chimneys with capes of this kind capable of preventing the penetration of rain into the chimney and ensuring draft regardless of the wind direction. Thus for example, the Swiss patent disclosure CH-492 933 describes a cape which comprises several tapered external linings which engage one in the other so as to delimit with an upper shutter and a lower element which extends the smoke duct of the pairs of superimposed annular passages.

Dans certaines constructions, notamment dans les villas individuelles, on prévoit souvent, à l'heure actuelle, une cheminée qui comporte deux ou plusieurs conduits de fumée parallèles, reliés par exemple l'un à une cheminée de salon et l'autre à un four à pain ou à un gril se trouvant dans une autre pièce. Or, les capes connues, adaptées à de telles cheminées, présentent l'inconvénient que l'effet de tirage obtenu par la garniture peut provoquer un refoulement de la fumée d'un conduit dans l'autre.In some constructions, in particular in individual villas, a chimney is often provided at present, which comprises two or more parallel smoke pipes, connected for example one to a living room fireplace and the other to an oven bread or grill in another room. However, the known capes, suitable for such chimneys, have the drawback that the draft effect obtained by the lining can cause a backflow of smoke from one duct into the other.

La présente invention a donc pour but de réaliser une cape efficace, dont la construction et le montage soient simples, et qui soit adaptée à des cheminées à plusieurs conduits de fumée, cette cape évitant l'inconvénient mentionné plus haut.The present invention therefore aims to achieve an efficient cape, whose construction and assembly are simple, and which is suitable for chimneys with several smoke ducts, this cape avoiding the drawback mentioned above.

Dans ce but, la cape de cheminée selon l'invention est caractérisée en ce qu'elle est agencée pour garnir une cheminée qui comporte au moins deux conduits de fumée parallèles, en ce que la garniture est un élément en forme de tronc de pyramide qui est relié à plusieurs éléments inférieurs adaptés chacun à un des conduits de fumée et qui est divisé en tronçons distincts par un ou plusieurs éléments de séparation jointifs chacun avec deux parois opposées de la garniture et avec une surface supérieure d'une paroi de séparation entre deux conduits de fumée.For this purpose, the chimney cap according to the invention is characterized in that it is arranged to garnish a chimney which comprises at least two parallel smoke ducts, in that the lining is an element in the form of a trunk of pyramid which is connected to several lower elements each adapted to one of the flues and which is divided into separate sections by one or more separating separating elements each with two opposite walls of the lining and with an upper surface of a partition wall between two smoke pipes.

On va décrire ci-après, à titre d'exemple, différentes formes d'exécution de l'objet de l'invention en se référant au dessin annexé dont

  • la fig. 1 est une vue en coupe selon la ligne I-I de la fig. 2 montrant une première forme d'exécution de la cape de cheminée,
  • la fig. 2 est une vue en coupe selon la ligne II-II de la fig. 1,
  • la fig. 3 est une vue en perspective de la première forme d'exécution et
  • la fig. 4 est une vue en perspective partiellement arrachée montrant une deuxième forme d'exécution de l'objet de l'invention.
Various embodiments of the subject of the invention will be described below, by way of example, with reference to the accompanying drawing,
  • fig. 1 is a sectional view along line II of FIG. 2 showing a first embodiment of the chimney cap,
  • fig. 2 is a sectional view along line II-II of FIG. 1,
  • fig. 3 is a perspective view of the first embodiment and
  • fig. 4 is a partially cutaway perspective view showing a second embodiment of the object of the invention.

De façon générale, la cape de cheminée est réalisée au moyen de segments de tôle métallique plane. De préférence, elle sera réalisée en cuivre. Tous les éléments de la cape sont reliés les uns aux autres, en principe par soudage et le bloc rigide d'un seul tenant que forme la cape, est fixé à un cadre par l'intermédiaire de charnières, de sorte qu'il peut être renversé pour libérer les conduits de fumée qui sont construits eux en maçonnerie.In general, the chimney breast is made by means of flat sheet metal segments. Preferably, it will be made of copper. All the elements of the cape are connected to each other, in principle by welding and the rigid block in one piece that forms the cape, is fixed to a frame by means of hinges, so that it can be overturned to free the smoke pipes which are built in masonry.

A la fig. 1, on voit l'extrémité supérieure d'une cheminée 1 en maçonnerie qui comporte deux conduits de fumée de section carrée 2 et 3. Entre ces deux conduits de fumée s'étend une paroi 4 dont la face supérieure 5 s'étend au même niveau que la face supérieure 6 du mur principal de la cheminée 1.In fig. 1, we can see the upper end of a masonry chimney 1 which includes two square section smoke ducts 2 and 3. Between these two smoke ducts extends a wall 4 whose upper face 5 extends at the same level than the upper face 6 of the main wall of the chimney 1.

La cape de cheminée proprement dit 7 se compose d'une garniture extérieure 8 en forme de tronc de pyramide, d'un élément supérieur 9, de deux éléments inférieurs 10 et 11, de forme tubulaire, adaptés chacun à un des conduits 2 et 3 et de deux éléments de séparation 12 et 13 qui, dans cette forme d'exécution, sont d'ailleurs confondus avec une des parois de chacun des éléments inférieurs 10 et 11. Ces différents éléments sont reliés les uns aux autres par des brides planes, de forme triangulaire, 14, par la jonction entre les plaques de séparation 12 et 13 et les pans de la garniture extérieure 8, et par des montants 15, situés aux quatre angles de la plaque rectangulaire supérieure 9. Les montants relient l'élément 9 avec le bord supérieur de la garniture extérieure 8. A la fig. 2, on voit la forme en plan de l'élément 12 dont le bord supérieur rectiligne et horizontal est soudé transversalement sous la plaque supérieure 9. Dans l'axe de chacun des conduits de fumée 2 et 3, on prévoit, sous la plaque supérieure 9, un bossage de forme pyramidale 18, formé de quatre segments de tôle découpés en triangle et soudés les uns aux autres. Les bossages 18 évitent des tourbillons sous la plaque 9. A la fig. 2, on voit également les pans longitudinaux de la garniture extérieure 8 et l'on voit que cette garniture délimite, par ses bords supérieur et inférieur, avec les éléments inférieurs 10 ou 11 et l'élément supérieur 9, des passages par où les mélanges d'air, de gaz et de fumée qui montent dans les conduits 2 ou 3 peuvent s'échapper selon les flèches montrées à la fig. 2.The chimney cap proper 7 consists of an outer lining 8 in the form of a pyramid trunk, an upper element 9, two lower elements 10 and 11, of tubular shape, each adapted to one of the conduits 2 and 3 and two separation elements 12 and 13 which, in this embodiment, are moreover confused with one of the walls of each of the lower elements 10 and 11. These different elements are connected to each other by plane flanges, of triangular shape, 14, by the junction between the separation plates 12 and 13 and the sides of the outer trim 8, and by uprights 15, located at the four corners of the upper rectangular plate 9. The uprights connect the element 9 with the upper edge of the outer trim 8. In fig. 2, we see the plan shape of the element 12, the rectilinear and horizontal upper edge of which is welded transversely under the upper plate 9. In the axis of each of the smoke ducts 2 and 3, provision is made under the upper plate 9, a pyramid-shaped boss 18, formed of four sheet metal segments cut into a triangle and welded to each other. The bosses 18 avoid swirls under the plate 9. In FIG. 2, we can also see the longitudinal sections of the outer lining 8 and we see that this lining defines, by its upper and lower edges, with the lower elements 10 or 11 and the upper element 9, passages through which the mixtures air, gas and smoke which rise in the conduits 2 or 3 can escape according to the arrows shown in fig. 2.

Un cadre 16 est fixé sur la face supérieure de la cheminée 1. Il est équipé de charnières 17 qui permettent de renverser la garniture d'un seul bloc le long d'un des grands côtés de la cheminée 1 lors des opérations de ramonage.A frame 16 is fixed on the upper face of the chimney 1. It is fitted with hinges 17 which make it possible to reverse the lining in one piece along one of the long sides of the chimney 1 during the sweeping operations.

La cape de cheminée 20 représentée à la fig. 4 est agencée pour équiper une cheminée 21 qui comporte quatre conduits de fumée 22. La cape 20 comporte, pour chaque conduit 22, un élément inférieur 23, de forme tubulaire et de section carrée, adapté au conduit. Ces éléments inférieurs sont distincts des éléments de séparation qui, dans ce cas, sont au nombre de trois et désignés par 24. Les éléments de séparation 24 sont des plaques de tôle dont la forme en plan correspond à celle des éléments 12 et 13 de la première forme d'exécution mais qui sont disposés de façon que leur bord inférieur repose au milieu de la face supérieure de chacune des trois cloisons de séparation 25 séparant les conduits de fumée 22. La cape 20 comporte une garniture extérieure 26 formée de deux segments de tôle longitudinaux et de deux segments de tôle transversaux, tous ces segments étant plans et étant découpés et soudés de façon à donner à la garniture la forme d'un tronc de pyramide. Des brides 27 et les bords des éléments de séparation 24 relient la garniture extérieure aux différents éléments inférieurs. La cape comporte en outre un élément supérieur 28 formé d'une plaque de couverture plane disposée au-dessus du bord supérieur de la garniture 26 et reliée à cette dernière par des montants intermédiaires 29 de même que par les bords des éléments de séparation 24.The chimney cap 20 shown in FIG. 4 is arranged to equip a chimney 21 which comprises four smoke ducts 22. The cap 20 comprises, for each duct 22, a lower element 23, of tubular shape and of square section, adapted to the duct. These lower elements are distinct from the separation elements which, in this case, are three in number and designated by 24. The separation elements 24 are sheet metal plates whose shape in plan corresponds to that of elements 12 and 13 of the first embodiment but which are arranged so that their lower edge rests in the middle of the upper face of each of the three partition walls 25 separating the smoke ducts 22. The cap 20 comprises an outer lining 26 formed of two segments of longitudinal sheet and two transverse sheet segments, all these segments being planar and being cut and welded so as to give the lining the shape of a pyramid trunk. Flanges 27 and the edges of the separating elements 24 connect the external lining to the various lower elements. The cape further comprises an upper element 28 formed by a flat cover plate disposed above the upper edge of the lining 26 and connected to the latter by intermediate uprights 29 as well as by the edges of the separation elements 24.

La cape d'un seul tenant, représentée à la fig. 4, est également reliée au cadre 30, qui est fixé sur la paroi supérieure de la cheminée 21, par des charnières (non représentées). On notera que dans ce cas, la plaque supérieure 28 n'est pas pourvue de bossages faisant saillie vers le bas mais, le cas échéant, de tels bossages pourraient également être prévus comme dans la première forme d'exécution. On notera également qu'au lieu d'être d'un seul tenant, la cape 20 pourrait être divisée en deux pièces séparées, l'élément de séparation 24 étant alors dédoublé et constituant une cloison extrême de chacune des deux parties de la cape 20.The cape in one piece, shown in fig. 4, is also connected to the frame 30, which is fixed to the upper wall of the chimney 21, by hinges (not shown). Note that in this case, the upper plate 28 is not provided with bosses projecting downwards, but, if necessary, such bosses could also be provided as in the first embodiment. It will also be noted that instead of being in one piece, the cap 20 could be divided into two separate parts, the separating element 24 then being split and constituting an extreme partition of each of the two parts of the cap 20 .

L'agencement décrit présente l'avantage d'être de construction simple tout en étant efficace. L'extrémité supérieure de chaque élément 23 débouche dans un espace qui est ouvert, selon les cas, sur deux, trois ou les quatre côtés et qui communique avec les passages ménagés de part et d'autre de la garniture extérieure. De plus, les éléments de séparation 12, 13 ou 24 empêchent, quelle que soit la direction du vent, que la fumée et les gaz sortant de l'un des conduits puissent pénétrer dans un autre.The arrangement described has the advantage of being simple in construction while being effective. The upper end of each element 23 opens into a space which is open, depending on the case, on two, three or all four sides and which communicates with the passages provided on either side of the external lining. In addition, the separating elements 12, 13 or 24 prevent, whatever the direction of the wind, that the smoke and the gases leaving one of the conduits can penetrate into another.

Finalement, le montage et l'entretien de la cape de cheminée et de la cheminée sur laquelle elle est montée sont également simplifiés.Finally, the assembly and maintenance of the chimney breast and the chimney on which it is mounted are also simplified.
