Description

DOMAINE TECHNIQUE DE L'INVENTONTECHNICAL FIELD OF THE INVENTON

La présente invention concerne de manière générale le doublage de parois à des fins d'isolation ou d'esthétique. Elle a plus particulièrement trait à un accessoire d'entretoisement placé transversalement entre la paroi à doubler et une cloison de doublage pour maintenir cette dernière à distance de la paroi à doubler.The present invention relates generally to the lining of walls for insulation or aesthetic purposes. It relates more particularly to a spacer accessory placed transversely between the wall to be lined and a lining partition to keep the latter at a distance from the wall to be lined.

ARRIERE PLAN TECHNOLOGIQUETECHNOLOGICAL BACKGROUND

Le doublage d'une paroi telle qu'un mur, un plafond ou un toit d'un bâtiment est fréquemment pratiqué, en rénovation ou en construction neuve, pour obtenir ou améliorer l'isolation acoustique ou thermique du bâtiment ou d'une pièce spécifique. A cet effet, une cloison de doublage (contre-cloison ou faux-plafond) est rapportée sur une ossature de doublage qui est elle-même fixée à des éléments de structure de la paroi à doubler, à distance donnée de celle-ci. Une garniture d'isolation thermique et/ou acoustique (souvent appelée complexe d'isolation) est insérée entre la paroi à doubler et la cloison de doublage.The lining of a wall such as a wall, a ceiling or a roof of a building is frequently practiced, in renovation or in new construction, to obtain or improve the acoustic or thermal insulation of the building or of a specific room. . For this purpose, a lining partition (counter-partition or false ceiling) is attached to a lining framework which is itself fixed to structural elements of the wall to be doubled, at a given distance from the latter. A thermal and / or acoustic insulation lining (often called an insulation complex) is inserted between the wall to be lined and the lining partition.

La garniture d'isolation inclut typiquement, d'une part, une ou plusieurs couches de matériau isolant fibreux tel que de la laine minérale et, d'autre part, au moins une membrane pare-vent ou pare-vapeur. Cette membrane est le plus souvent intercalée entre la couche de matériau fibreux et la cloison de doublage, typiquement accolée à la cloison, éventuellement intercalée entre deux couches de matériau fibreux.The insulation lining typically includes, on the one hand, one or more layers of fibrous insulating material such as mineral wool and, on the other hand, at least one wind barrier or vapor barrier. This membrane is most often interposed between the layer of fibrous material and the lining partition, typically attached to the partition, optionally interposed between two layers of fibrous material.

La fixation de l'ossature de doublage aux éléments de structure de la paroi à doubler est réalisée au moyen d'accessoires d'entretoisement régulièrement espacés. Chaque accessoire d'entretoisement comporte un corps principal en forme de tige s'étendant transversalement à la paroi à doubler et à la cloison de doublage, dont une extrémité est pourvue de moyens de sa fixation en porte-à-faux à un élément de structure de la paroi à doubler et dont l'autre extrémité est pourvue de moyens de son assemblage avec l'ossature de doublage. Un tel accessoire d'entretoisement est par exemple connu du document WO2006/061538 .The fixing of the lining frame to the structural elements of the wall to be doubled is carried out by means of regularly spaced bracing accessories. Each bracing accessory comprises a main body in the form of a rod extending transversely to the wall to be lined and to the lining partition, one end of which is provided with means for its cantilever attachment to a structural element. of the wall to be doubled and the other end of which is provided with means for its assembly with the doubling framework. Such a spacer accessory is for example known from the document WO2006 / 061538 .

Lors de l'installation, la garniture d'isolation est généralement embrochée sur les tiges des accessoires d'entretoisement, ce qui provoque un percement multiple des couches de matériau fibreux et le cas échéant de la membrane. Ce percement est particulièrement préjudiciable en ce qui concerne les membranes, car leur fonction d'étanchéité, permanente ou sélective, est alors altérée. Le percement de la membrane peut en outre constituer une amorce de déchirure de nature à se propager si une tension est exercée sur la membrane.During installation, the insulation trim is generally plugged into the rods of the spacer accessories, which causes multiple holes in the layers of fibrous material and possibly the membrane. This piercing is particularly detrimental as regards the membranes, because their sealing function, permanent or selective, is then impaired. The piercing of the membrane can also constitute a tear initiation capable of propagating if a tension is exerted on the membrane.

Pour éviter en partie ce problème, il est connu de disposer la membrane du côté intérieur de l'ossature de doublage, entre cette dernière et la cloison de doublage. La membrane n'est ainsi pas traversée par l'accessoire d'entretoisement et peut ainsi rester intègre, du moins dans un premier temps.To partially avoid this problem, it is known practice to place the membrane on the inside of the lining framework, between the latter and the lining partition. The membrane is thus not crossed by the spacer accessory and can thus remain intact, at least initially.

Cette solution n'est cependant que partielle. La fixation de la cloison de doublage sur l'ossature de doublage implique le percement de la membrane par les éléments de fixation (agrafes, vis, clous, etc.), ce qui nuit, bien que dans une moindre mesure, à l'étanchéité de la membrane.This solution is however only partial. Fixing the lining partition to the lining framework involves piercing the membrane by the fastening elements (staples, screws, nails, etc.), which, although to a lesser extent, affects the waterproofing. of the membrane.

Le positionnement de la membrane devant l'ossature de doublage soulève un autre problème technique : il ne laisse subsister aucun espace interstitiel entre la membrane et la cloison de doublage. Or, il s'avère souvent nécessaire d'insérer, derrière la cloison de doublage, différents câbles ou tuyaux notamment de réseau d'eau, de ventilation, d'électricité ou de communication. Il est alors difficilement envisageable de placer les câbles et accessoires de câblage entre la membrane et la cloison de doublage. Les câbles ne pourraient en effet être convenablement fixés qu'à la faveur d'ouvertures ménagées dans la membrane. La membrane risquerait en outre d'être blessée ou distendue par les câbles ou des accessoires de gainage, fixation ou raccordement.The positioning of the membrane in front of the lining framework raises another technical problem: it does not leave any interstitial space between the membrane and the lining partition. However, it is often necessary to insert, behind the lining partition, various cables or pipes, in particular for the water, ventilation, electricity or communication network. It is then difficult to envisage placing the cables and cabling accessories between the membrane and the lining partition. The cables could in fact be properly fixed only by means of openings made in the membrane. The membrane could also be injured or stretched by cables or sheathing, fixing or connection accessories.

Ces câbles peuvent certes être disposés derrière la membrane. Mais il n'est alors plus possible d'y accéder pour la maintenance ou l'évolution de l'installation de câblage sans retirer la membrane ou y pratiquer une ouverture. En outre, les opérations de câblage peuvent, pour des raisons de logistique ou d'évolution des besoins ou des technologies, intervenir postérieurement au doublage de la paroi, ce qui nécessite également la dépose ou l'ouverture de la membrane par des intervenants qui ne sont généralement pas spécialisés dans le doublage de parois et l'isolation.These cables can certainly be placed behind the membrane. However, it is then no longer possible to access it for maintenance or upgrading the cabling installation without removing the membrane or making an opening in it. In addition, the cabling operations may, for reasons of logistics or changing needs or technologies, occur after the lining of the wall, which also requires the removal or opening of the membrane by workers who do not. are generally not specialized in wall lining and insulation.

DESCRIPTION DETAILLEEDETAILED DESCRIPTION

Dans l'exemple illustré par la figure 1, il s'agit plus spécifiquement d'isoler les combles d'un bâtiment et, à cet effet, de doubler un mur extérieur 1 et une toiture 2 de ce bâtiment.In the example illustrated by figure 1 , it is more specifically a matter of insulating the attic of a building and, for this purpose, of lining an exterior wall 1 and a roof 2 of this building.

La toiture 2 comporte ici, classiquement, une charpente en bois constituée de pannes 3 portant des chevrons 4 sur lesquels reposent des éléments de couverture 5.The roof 2 comprises here, conventionally, a wooden frame made up of purlins 3 carrying rafters 4 on which the roofing elements 5 rest.

Un dispositif de doublage, conforme à l'invention, est rapporté sur la charpente de toit et sur le mur extérieur. Ce dispositif de doublage comporte une ossature de doublage, composée d'une part de lattes horizontales 6 pour le doublage de la toiture et d'autre part de lattes verticales 7 pour le doublage du mur 1. Ces lattes sont communément appelées fourrures dans le cas des murs ou chevrons /ou poutres dans le cas d'une toiture.A doubling device, according to the invention, is attached to the roof frame and to the exterior wall. This doubling device comprises a doubling framework, made up on the one hand of horizontal slats 6 for lining the roof. and on the other hand vertical slats 7 for lining the wall 1. These slats are commonly called furring in the case of walls or rafters / or beams in the case of a roof.

Les lattes de doublage 6 et 7 sont respectivement fixées à des éléments de structure de la toiture 2 et du mur 1 à doubler au moyen d'une pluralité d'accessoires d'entretoisement 10.The lining slats 6 and 7 are respectively fixed to structural elements of the roof 2 and of the wall 1 to be doubled by means of a plurality of bracing accessories 10.

Chaque accessoire d'entretoisement 10, visible aux figures 2a et 2b, comporte une portion centrale 11, s'étendant selon un axe X1, se présentant, dans un premier mode de réalisation, sous la forme d'une tige 12 pourvue de moyens de sa fixation 14 à une paroi qui peut être une toiture 2 ou un mur 1 et dont l'autre extrémité, dite avant, est pourvue d'une pièce de raccord pourvu de moyens de son assemblage 30 avec la latte 6, 7 dont l'accessoire assure le maintien. Au montage, la tige 12 est disposée pour s'étendre suivant une direction sensiblement perpendiculaire au mur 1. Dans le cas d'une toiture, la tige 12 est disposée pour s'étendre suivant une direction sensiblement verticale par rapport au sol afin de faire un faux plafond horizontal par rapport au sol. Des panneaux de matériaux isolants sont agencés entre la toiture 2 ou le mur 1 et les lattes 6, 7 utilisées pour porter une paroi de doublage.Each bracing accessory 10, visible at figures 2a and 2b , comprises a central portion 11, extending along an axis X1, being, in a first embodiment, in the form of a rod 12 provided with means for its attachment 14 to a wall which may be a roof 2 or a wall 1 and the other end of which, called the front end, is provided with a connecting piece provided with means for its assembly 30 with the slat 6, 7, the accessory of which ensures the maintenance. During assembly, the rod 12 is arranged to extend in a direction substantially perpendicular to the wall 1. In the case of a roof, the rod 12 is arranged to extend in a direction substantially vertical relative to the ground in order to a false ceiling horizontal to the ground. Insulating material panels are arranged between the roof 2 or the wall 1 and the slats 6, 7 used to support a lining wall.

Les accessoires d'entretoisement 10 qui servent au doublage de la toiture sont fixés aux chevrons 4. Ils comportent à cet effet chacun, comme moyens de fixation 14, une platine ou base longitudinale de fixation 141 vissée sur le flanc du chevron 4 concerné. Les accessoires d'entretoisement 10 qui sont fixés au mur 1 comportent à cet effet chacun, comme moyens de fixation 14, au moyen d'une platine transversale de fixation 142 vissée sur le mur 1.The bracing accessories 10 which are used for lining the roof are fixed to the rafters 4. For this purpose, they each comprise, as fixing means 14, a longitudinal fixing plate or base 141 screwed onto the side of the rafter 4 concerned. The bracing accessories 10 which are fixed to the wall 1 each comprise for this purpose, as fixing means 14, by means of a transverse fixing plate 142 screwed on the wall 1.

Les platines 141, 142 peuvent être faites de matière avec la tige 12 ou être des pièces rapportées à la tige 12 par l'intermédiaire de moyens divers.The plates 141, 142 can be made of material with the rod 12 or be parts attached to the rod 12 by means of various means.

Selon une caractéristique avantageuse visible à la figure 3, la tige 12 est conçue pour permettre un réglage de sa longueur. La tige 12 comporte une première partie 121 et une seconde partie 123. Les moyens de fixation 14 de la tige sont agencés sur la première partie 121 alors que les moyens d'assemblage 30 avec la latte 6, 7 dont l'accessoire assure le maintien sont agencés sur la seconde partie 123 et inversement. Des moyens de réglage 125 sont prévus pour permettre d'ajuster la position de la seconde partie 123 par rapport à la première partie 121 pour ainsi ajuster la longueur de la tige 12. Ces moyens de réglage 125 permettent, par exemple, à la première partie 121 et à la seconde partie 123 de coulisser l'une par rapport à l'autre. Ce mouvement de coulissage est opéré par l'intermédiaire par exemple, d'un système de rails ou d'un système utilisant un tube dans lequel une tige coulissante coulisse. Mais d'autres systèmes comme un système dans lequel les deux parties se fixent par cran sont utilisables.According to an advantageous characteristic visible at the figure 3 , the rod 12 is designed to allow adjustment of its length. The rod 12 comprises a first part 121 and a second part 123. The fixing means 14 of the rod are arranged on the first part 121 while the assembly means 30 with the slat 6, 7, the accessory of which ensures the maintenance. are arranged on the second part 123 and vice versa. Adjustment means 125 are provided to make it possible to adjust the position of the second part 123 relative to the first part 121 to thus adjust the length of the rod 12. These adjustment means 125 allow, for example, the first part 121 and the second part 123 to slide relative to each other. This sliding movement is effected by means of, for example, a rail system or a system using a tube in which a sliding rod slides. But other systems such as a system in which the two parts are fixed by notch can be used.

Chaque accessoire d'entretoisement présente ainsi une longueur hors tout (correspondant à la distance entre ses points extrêmes suivant sa direction longitudinale) typiquement comprise entre 200 et 350 millimètres lorsqu'il est pourvu de toutes ses platines de fixation.Each spacer accessory thus has an overall length (corresponding to the distance between its end points in its longitudinal direction) typically between 200 and 350 millimeters when it is provided with all its fixing plates.

La tige 12 comprend, à une extrémité, à l'opposé des moyens de fixation 14, des moyens d'installation 13 d'une membrane. Ces moyens d'installation 13 comprennent une première mâchoire 15 et une seconde mâchoire 17. La première mâchoire 15 est fixée à la portion centrale 11 ou est faite de matière avec ladite portion centrale 11 comme visible à la figure 4.The rod 12 comprises, at one end, opposite the fixing means 14, means 13 for installing a membrane. These installation means 13 comprise a first jaw 15 and a second jaw 17. The first jaw 15 is fixed to the central portion 11 or is made of material with said central portion 11 as visible at the bottom. figure 4 .

La première mâchoire 15 coopère avec la seconde mâchoire 17 par l'intermédiaire de moyens d'accouplage 19. Ces moyens d'accouplage 19 sont portés par la première mâchoire 15 et la seconde mâchoire 17.The first jaw 15 cooperates with the second jaw 17 by means of coupling means 19. These coupling means 19 are carried by the first jaw 15 and the second jaw 17.

Selon l'invention, les moyens d'accouplage 19 sont agencés pour permettre le serrage axial de la seconde mâchoire 17 avec la première mâchoire 15 tout en permettant le pincement entre elles, après accouplage, de la membrane M. Encore plus précisément, ce pincement de la membrane M par la première mâchoire 15 et la seconde mâchoire 17 permet d'éviter d'embrocher, de percer ladite membrane et ainsi ne pas le fragiliser ou créer des pertes localisées de performances.According to the invention, the coupling means 19 are arranged to allow the axial clamping of the second jaw 17 with the first jaw 15 while allowing the clamping between them, after coupling, of the membrane M. Even more precisely, this clamping of the membrane M by the first jaw 15 and the second jaw 17 makes it possible to avoid plugging in, piercing said membrane and thus not weakening it or creating localized losses of performance.

Selon l'invention, la seconde mâchoire 17 comprend deux demi-mâchoires 170. Ces demi-mâchoires 170 sont agencées pour coopérer l'une l'autre et s'assembler afin de former la seconde mâchoire 17.According to the invention, the second jaw 17 comprises two half-jaws 170. These half-jaws 170 are arranged to cooperate with each other and to assemble in order to form the second jaw 17.

La fixation des demi-mâchoires 170 se fait par l'intermédiaire de moyens d'assemblage 18 comme visibles à la figure 5. Ces moyens d'assemblage 18 peuvent prendre différentes formes pour permettre aux demi-mâchoires 170 de s'assembler.The fixing of the half-jaws 170 is done by means of assembly means 18 as visible at the figure 5 . These assembly means 18 can take different forms to allow the half-jaws 170 to assemble.

Selon un premier exemple, les deux demi-mâchoires 170 sont assemblées l'une à l'autre par vissage. Les demi-mâchoires sont agencées pour permettre à une vis d'assembler les deux demi-mâchoires.According to a first example, the two half-jaws 170 are assembled together by screwing. The half-jaws are arranged to allow a screw to assemble the two half-jaws.

Selon un second exemple visible à la figure 6, les deux demi-mâchoires 170 sont assemblées l'une à l'autre par un système à encliquetage.According to a second example visible at figure 6 , the two half-jaws 170 are assembled to one another by a snap-fit system.

Ce système à encliquetage comprend au moins une lame déformable 181 munie d'un cran et agencée sur une demi-mâchoire alors que l'autre demi-mâchoire comprend au moins un logement 182. La lame déformable est apte à se déformer pour entrer ou sortir du logement, ce dernier comprenant une encoche dans laquelle le cran s'insère.This snap-in system comprises at least one deformable blade 181 provided with a notch and arranged on a half-jaw while the other half-jaw comprises at least one housing 182. The deformable blade is able to deform to enter or leave the housing, the latter comprising a notch in which the notch is inserted.

Selon une alternative visible aux figures 7 et 8, le système à encliquetage est tel que chaque demi-mâchoire est munie d'une lame 183 et d'un logement 184, ledit logement 184 étant agencé pour être en regard de la lame 183 de l'autre mâchoire. La lame 183 comprend, optionnellement, un relief ou crantage 183' permettant un meilleur assemblage des demi-mâchoires 170.According to a visible alternative to figures 7 and 8 , the snap-in system is such that each half-jaw is provided with a blade 183 and a housing 184, said housing 184 being arranged to be facing the blade 183 of the other jaw. The blade 183 optionally comprises a relief or notch 183 'allowing better assembly of the half-jaws 170.

Dans une variante des exemples visible aux figures 8 et 9, les deux demi-mâchoires 170 sont solidaires par un système de charnière 185. Ce système de charnière 185 peut être une bande de matière déformable ou un système de gond et penture ou utiliser une lame 183 et un logement 184. Cette charnière permet aux demi-mâchoires 170 de pivoter selon un axe parallèle ou orthogonal à l'axe central de la portion centrale.In a variant of the examples visible in figures 8 and 9 , the two half-jaws 170 are secured by a hinge system 185. This hinge system 185 can be a strip of deformable material or a hinge and hinge system or use a blade 183 and a housing 184. This hinge allows the half -jaws 170 to pivot along an axis parallel or orthogonal to the central axis of the central portion.

Selon un autre exemple, les deux demi-mâchoires 170 sont assemblées l'une à l'autre par insertion d'au moins une lame s'étendant depuis l'une des demi-mâchoires vers un logement agencé sur l'autre demi-mâchoire.According to another example, the two half-jaws 170 are assembled to one another by inserting at least one blade extending from one of the half-jaws towards a housing arranged on the other half-jaw .

Astucieusement selon l'invention, les deux demi-mâchoires 170 sont conçues pour, lors de leur verrouillage, coopérer avec la première mâchoire 15 pour emprisonner, pincer la membrane. Pour cela, les moyens d'accouplage 19 sont utilisés.Cleverly according to the invention, the two half-jaws 170 are designed to, during their locking, cooperate with the first jaw 15 to trap and pinch the membrane. For this, the coupling means 19 are used.

Ces moyens d'accouplage 19 fonctionnent sur le principe de surfaces complémentaires primaires 191 et secondaires 192 coopérant ensemble pour assembler le tout. Ces surfaces complémentaires primaires 191 et secondaires 192 permettent ainsi de pincer la membrane sans l'endommager.These coupling means 19 operate on the principle of complementary primary 191 and secondary 192 surfaces cooperating together to assemble the whole. These complementary primary 191 and secondary 192 surfaces thus make it possible to pinch the membrane without damaging it.

Pour se faire, la figure 10 représente la première mâchoire 15 qui se présente sous la forme d'une pièce de forme quelconque 150 ayant une paroi latérale 151 c'est-à-dire une paroi sensiblement parallèle à l'axe de la portion centrale 11.

Cette paroi latérale 151 comprend au moins une zone formant une surface complémentaire primaire 191.To do so, the figure 10 shows the first jaw 15 which is in the form of a piece of any shape 150 having a side wall 151 that is to say a wall substantially parallel to the axis of the central portion 11. The piece forming the first jaw 15 comprises an upper surface 152 and a lower surface 153. This side wall 151 comprises at least one zone forming a primary complementary surface 191.

Chaque demi-mâchoire 170 formant la seconde mâchoire 17 se présente sous la forme d'un bloc 171 muni d'une partie saillante 172 comme visible à la figure 10. Le bloc 171 formant la demi-mâchoire 170 présente une forme de profilé ou de quart de sphère ou toutes formes quelconques aptes à être utilisées. Cette partie saillante 172 forme une paroi latérale 173 s'étendant sensiblement parallèle à l'axe de la portion centrale 11. La paroi latérale 173 de la partie saillante de chaque demi-mâchoire 170 est configurée pour former la surface complémentaire secondaire 192. Chaque demi-mâchoire 170 comprend une face supérieure et une face inférieure, la face inférieure est la face en regard de la première mâchoire 15.Each half-jaw 170 forming the second jaw 17 is in the form of a block 171 provided with a protruding part 172 as visible at the bottom. figure 10 . the block 171 forming the half-jaw 170 has the shape of a section or quarter-sphere or any shape that can be used. This protruding part 172 forms a side wall 173 extending substantially parallel to the axis of the central portion 11. The side wall 173 of the protruding part of each half-jaw 170 is configured to form the secondary complementary surface 192. Each half -jaw 170 comprises an upper face and a lower face, the lower face is the face opposite the first jaw 15.

Idéalement, la paroi latérale 173 de la partie saillante 172 de chacune des demi-mâchoires 170 est configurée pour former une surface complémentaire secondaire 192 par demi-mâchoire 170. Dans ce cas, la paroi latérale 151 de la première mâchoire 15 comprend au moins une zone formant la surface complémentaire primaire 191, cette zone s'étendant de façon à coopérer avec la surface complémentaire secondaire 192 de chaque demi-mâchoire 170. Alternativement, la paroi latérale 151 de la première mâchoire 15 comprend une pluralité de zones formant la surface complémentaire primaire 191, idéalement, un nombre identique au nombre de surfaces complémentaires secondaires 192.Ideally, the side wall 173 of the protrusion 172 of each of the half-jaws 170 is configured to form a secondary complementary surface 192 per half-jaw 170. In this case, the side wall 151 of the first jaw 15 comprises at least one. zone forming the primary complementary surface 191, this zone extending so as to cooperate with the secondary complementary surface 192 of each half-jaw 170. Alternatively, the side wall 151 of the first jaw 15 comprises a plurality of zones forming the complementary surface primary 191, ideally a number identical to the number of secondary complementary surfaces 192.

Selon un premier exemple visible aux figures 11a et 11b, la première mâchoire 15 se présente sous la forme d'une plaque 150 d'épaisseur constante et de forme régulière. Cette forme peut être circulaire, carrée, rectangulaire ou toute autre forme régulière. Cette plaque 150 présente une paroi latérale 151 périphérique, ladite paroi 151 étant sensiblement parallèle à l'axe de la portion centrale 11.According to a first example visible to figures 11a and 11b , the first jaw 15 is in the form of a plate 150 of constant thickness and regular shape. This shape can be circular, square, rectangular or any other regular shape. This plate 150 has a peripheral side wall 151, said wall 151 being substantially parallel to the axis of the central portion 11.

Dans ce premier exemple, les parties saillantes 172 d'une demi-mâchoire 170 configurées pour former la surface complémentaire secondaire 192 comprennent un crochet 174. Ce crochet 174 est du type en L et comprend une portion 174a s'étendant sensiblement parallèlement à l'axe de la portion centrale et une portion 174b s'étendant orthogonalement à l'axe de la portion centrale. Ce crochet 174 est dimensionné pour que l'espace E entre la portion s'étendant orthogonalement 174b à l'axe de la portion centrale et la surface 171a de la demi mâchoire 170 soit tel que la première mâchoire 15 puisse s'y insérer. Dans ce cas, la portion s'étendant orthogonalement 174b à l'axe de la portion centrale est au contact de la surface inférieure de la première mâchoire 15.In this first example, the protrusions 172 of a half-jaw 170 configured to form the secondary complementary surface 192 comprise a hook 174. This hook 174 is of the L-type and comprises a portion 174a extending substantially parallel to the hook. axis of the central portion and a portion 174b extending orthogonally to the axis of the central portion. This hook 174 is dimensioned so that the space E between the portion extending orthogonally 174b to the axis of the central portion and the surface 171a of the half jaw 170 is such that the first jaw 15 can be inserted therein. In this case, the portion extending orthogonally 174b to the axis of the central portion is in contact with the lower surface of the first jaw 15.

Dans une variante de ce premier exemple, la plaque 150 est constituée de deux tronçons faisant saillie de l'extrémité de la tige 12. Ces deux tronçons sont réalisés de sorte à pouvoir s'insérer dans l'espace E. Préférentiellement, les deux tronçons s'étendent sur une longueur d'au plus 5mm, de préférence d'au plus 3mm.In a variant of this first example, the plate 150 consists of two sections projecting from the end of the rod 12. These two sections are made so as to be able to fit into the space E. Preferably, the two sections extend over a length of at most 5mm, preferably at most 3mm.

Ainsi, lors du montage des deux demi-mâchoires, la plaque 150 formant la première mâchoire 15 s'insère dans l'espace E de chaque demi-mâchoire 170.Thus, during the assembly of the two half-jaws, the plate 150 forming the first jaw 15 is inserted into the space E of each half-jaw 170.

Dans un second exemple visible aux figures 12a et 12b, la première mâchoire 15 se présente sous la forme d'un bloc 150' comprenant une face inférieure 153', une face supérieure 152' et une paroi latérale 151'. Ce bloc peut présenter un décrochement sur deux faces latérales opposées afin d'avoir un profil en escalier. Dans le cas d'un tel décrochement, la paroi latérale est en deux parties : une partie haute 151a' et une partie basse 151b'. Cette première mâchoire 15 comprend au moins une gorge 193 s'étendant dans le plan de la première mâchoire 15, orthogonalement à l'axe de la portion centrale. Cette gorge 193 forme une surface complémentaire primaire 191. Cette gorge 193 est agencée sur la paroi latérale 151' en partie basse ou partie haute. Cette gorge 193 peut également être agencée au niveau de la jointure entre la partie haute 151a' et la partie basse 151b'. Idéalement, la première mâchoire 15 comprend deux gorges 193, une pour chaque demi-mâchoire 170', ces gorges 193 étant agencées pour être diamétralement opposées.In a second example visible to figures 12a and 12b , the first jaw 15 is in the form of a block 150 'comprising a lower face 153', an upper face 152 'and a side wall 151'. This block may have a recess on two opposite side faces in order to have a stepped profile. In the case of such a step, the side wall is in two parts: an upper part 151a 'and a lower part 151b'. This first jaw 15 comprises at least one groove 193 extending in the plane of the first jaw 15, orthogonally to the axis of the central portion. This groove 193 forms a primary complementary surface 191. This groove 193 is arranged on the side wall 151 'in the lower part or the upper part. This groove 193 can also be arranged at the joint between the upper part 151a 'and the lower part 151b'. Ideally, the first jaw 15 comprises two grooves 193, one for each half-jaw 170 ', these grooves 193 being arranged to be diametrically opposed.

Cette gorge 193 est apte à coopérer avec la surface complémentaire secondaire 192 d'une demi-mâchoire 170.This groove 193 is able to cooperate with the secondary complementary surface 192 of a half-jaw 170.

Dans ce second exemple, la partie saillante 172 de chaque demi-mâchoire 170' se présente sous la forme d'une portion s'étendant sensiblement parallèlement à l'axe de la portion centrale. Cette portion 172 comprend un relief 194, formant la surface complémentaire secondaire 192, sous la forme d'une ligne dont la forme et les dimensions permettent audit relief 194 de s'insérer dans la gorge 193 de la première mâchoire.In this second example, the projecting part 172 of each half-jaw 170 'is in the form of a portion extending substantially parallel to the axis of the central portion. This portion 172 comprises a relief 194, forming the secondary complementary surface 192, in the form of a line whose shape and dimensions allow said relief 194 to fit into the groove 193 of the first jaw.

Alternativement, la surface complémentaire primaire 191 de la première mâchoire 15 peut présenter un relief 194 et la surface complémentaire secondaire 192 de chaque demi- mâchoire 170 peut présenter une gorge 193.Alternatively, the primary complementary surface 191 of the first jaw 15 can have a relief 194 and the secondary complementary surface 192 of each half-jaw 170 can have a groove 193.

Ainsi, lors du montage des demi-mâchoires 170, les reliefs 194 s'insèrent dans les gorges 193 pour permettre l'accouplage de la seconde mâchoire 17 avec la première mâchoire 15.Thus, during the assembly of the half-jaws 170, the reliefs 194 are inserted into the grooves 193 to allow the coupling of the second jaw 17 with the first jaw 15.

Dans un troisième exemple visible aux figures 13a, 13b, 13c, la première mâchoire 15 se présente sous la forme d'une plaque d'épaisseur 150" constante et de forme régulière. Cette forme peut être circulaire, carrée, rectangulaire ou toute autre forme régulière. Cette plaque présente une paroi latérale périphérique 151", une face supérieure 152" et une face inférieure 153" par laquelle elle est attachée à la portion centrale 11. Cette plaque 150" peut présenter un décrochement sur deux faces latérales opposées afin d'avoir un profil en escalier. Dans le cas d'un tel décrochement, la paroi latérale est en deux parties : une partie haute et une partie basse.In a third example visible to figures 13a, 13b, 13c , the first jaw 15 is in the form of a plate of constant thickness 150 "and of regular shape. This shape may be circular, square, rectangular or any other regular shape. This plate has a peripheral side wall 151", a face upper 152 "and a lower face 153" by which it is attached to the central portion 11. This plate 150 "can have a step on two opposite side faces in order to have a stepped profile. In the case of such a step. , the side wall is in two parts: an upper part and a lower part.

Cette paroi 151" est telle agencée pour présente au moins une portion inclinée 151c" formant la surface complémentaire primaire 191". Cette portion inclinée 151c" peut s'étendre sur toute la paroi latérale 151" de la partie haute ou de la partie basse. Cette portion inclinée 151c" peut aussi s'étendre de sorte à permettre à la surface complémentaire secondaire 192" de chaque demi-mâchoire 170 de coopérer avec ladite portion inclinée. Alternativement, la première mâchoire 15 comprend deux portions inclinées 151c". L'inclinaison de la ou des portions inclinées 151c" est telle que la surface de la face supérieure soit plus important que celle de la face inférieure. La première mâchoire 15 présente un profil sensiblement en forme de trapèze.This wall 151 "is such arranged to present at least one inclined portion 151c" forming the primary complementary surface 191 ". This inclined portion 151c" can extend over the entire side wall 151 "of the upper part or of the lower part. This inclined portion 151c "can also extend so as to allow the secondary complementary surface 192" of each half-jaw 170 to cooperate with said inclined portion. Alternatively, the first jaw 15 comprises two inclined portions 151c ". The inclination of the inclined portion (s) 151c "is such that the surface of the upper face is greater than that of the lower face. The first jaw 15 has a profile substantially in the shape of a trapezoid.

Dans ce troisième exemple, la partie saillante 172 de chaque demi-mâchoire 170 peut présenter différentes formes.In this third example, the projecting part 172 of each half-jaw 170 can have different shapes.

Une première forme consiste en une lame 1720 ou plaque s'étendant de façon inclinée depuis ladite demi-mâchoire. Une seconde forme de la partie saillante consiste en un profilé 1721, plein ou creux, présentant en forme munie d'une surface inclinée telle une forme triangulaire rectangle, trapézoïdale rectangle ou autres. La surface inclinée de la partie saillante 172 forme ainsi, avec la surface de la demi-mâchoire 170 à partir de laquelle elle s'étend, un logement.A first form consists of a blade 1720 or plate extending inclined from said half jaw. A second form of the projecting part consists of a section 1721, solid or hollow, having a shape provided with an inclined surface such as a triangular rectangle, trapezoidal rectangle or the like. The inclined surface of the protrusion 172 thus forms, together with the surface of the half-jaw 170 from which it extends, a housing.

La surface inclinée de la partie saillante 172 est agencée pour coopérer avec la surface inclinée de la première mâchoire afin que la partie saillante s'emboite parfaitement avec la surface inclinée de la première mâchoire 15. La surface inclinée de la première mâchoire 15 entre ainsi dans le logement formé par la surface inclinée de la partie saillante 172 et la surface de la demi-mâchoire 170 à partir de laquelle ladite partie saillante s'étend.The inclined surface of the protrusion 172 is arranged to cooperate with the inclined surface of the first jaw so that the protrusion fits perfectly with the inclined surface of the first jaw 15. The inclined surface of the first jaw 15 thus enters into. the housing formed by the inclined surface of the protrusion 172 and the surface of the half-jaw 170 from which said protrusion extends.

Dans le cas d'une première mâchoire 15 ayant un décrochement et un profil en escalier, la partie haute et/ou la partie basse peuvent présenter une surface inclinée. Les demi-mâchoires 170 sont agencées pour avoir une ou deux surfaces inclinées pour coopérer avec la ou les surfaces inclinées de la première mâchoire 15.In the case of a first jaw 15 having a step and a stepped profile, the upper part and / or the lower part may have an inclined surface. The half-jaws 170 are arranged to have one or two inclined surfaces to cooperate with the one or more inclined surfaces of the first jaw 15.

Cette mâchoire 15 est une pièce qui est faite de matière, monobloc avec la tige 12 ou une pièce rapportée qui se fixe à la tige 12. Dans le cas d'une pièce rapportée, la plaque 150, 150', 150" comprend un trou traversant ou non agencé directement dans la plaque ou dans une excroissance s'étendant depuis la plaque. Cela permet à la première mâchoire 15 d'être vissée ou encliquetée ou chassée sur la tige 12. Le procédé de mise en place comprend une étape de fixation de la portion centrale sur la paroi P à doubler via les moyens de fixation 14 visible à la figure 14a. Cette fixation utilise des vis ou clou ou colle pour fixer la portion centrale 11 orthogonalement à la paroi à doubler.This jaw 15 is a part which is made of material, integral with the rod 12 or an insert which attaches to the rod 12. In the case of an insert, the plate 150, 150 ', 150 "includes a hole crossing or not directly arranged in the plaque or in a growth extending from the plaque. This allows the first jaw 15 to be screwed or snapped or driven on the rod 12. The installation method comprises a step of fixing the central portion on the wall P to be doubled via the fixing means 14 visible at the bottom. figure 14a . This fixing uses screws or nails or glue to fix the central portion 11 orthogonally to the wall to be lined.

Ensuite, une étape de réglage de la longueur de la portion centrale est réalisée si ladite portion centrale 11 est réglable, visible à la figure 14b. Cette étape consiste à manipuler les moyens de réglage 125 pour permettre d'ajuster la longueur de la portion centrale, celle-ci comportant une première partie et une seconde partie qui coulissent l'une par rapport à l'autre.Then, a step of adjusting the length of the central portion is carried out if said central portion 11 is adjustable, visible at the bottom. figure 14b . This step consists in manipulating the adjustment means 125 to allow the length of the central portion to be adjusted, the latter comprising a first part and a second part which slide relative to one another.

Après cette étape de réglage, une étape consistant à mettre en place l'isolant avec l'aide dudit accessoire d'entretoisement est réalisée. Cet isolant est placé entre la paroi à isoler et la première mâchoire. Cette mise en place diffère selon la configuration du dispositif d'entretoisement.After this adjustment step, a step consisting in fitting the insulation with the help of said spacer accessory is carried out. This insulator is placed between the wall to be insulated and the first jaw. This placement differs depending on the configuration of the spacer device.

Une première manière de poser l'isolant est de l'embrocher sur la tige 12. Cette manière de poser l'isolant est possible si la première mâchoire est une pièce rapportée sur la tige 12. Cet embrochement est réalisé avant la mise en place de la première mâchoire 15.A first way of fitting the insulator is to plug it in on the rod 12. This way of fitting the insulator is possible if the first jaw is a part attached to the rod 12. This plug-in is made before the installation of the the first jaw 15.

Une seconde manière de poser l'isolant consiste à l'agencer afin qu'il prenne appui sur la surface inférieure 153, 153', 153".A second way of installing the insulation consists in arranging it so that it bears on the lower surface 153, 153 ', 153 ".

Cette surface inférieure 153, 153', 153" comprend, dans une première option, des dents. Ces dents s'étendent orthogonalement à la surface inférieure 153, 153', 153". Ces dents permettent d'embrocher l'isolant pour le maintenir.This lower surface 153, 153 ', 153 "comprises, in a first option, teeth. These teeth extend orthogonally to the lower surface 153, 153', 153". These teeth allow the insulation to be plugged in to hold it.

Selon une seconde option, le dispositif d'entretoisement comprend une platine supplémentaire fixée à la tige 12. Cette platine comprend une surface sur laquelle l'isolant prend appui.According to a second option, the spacer device comprises an additional plate fixed to the rod 12. This plate comprises a surface on which the insulation rests.

Cette seconde manière est possible pour une première mâchoire 15 de matière avec la tige 12 ou rapportée à celle-ci.This second way is possible for a first jaw 15 made of material with the rod 12 or attached thereto.

Dans le cas d'une première mâchoire 15 qui n'est pas faite de matière avec la tige, une étape optionnelle (visible à la figure 14c) consiste en la fixation de la première mâchoire à la portion principale est réalisée. En effet, dans ce cas, le kit du dispositif d'entretoisement comprend une portion centrale, une première mâchoire 15 et une seconde mâchoire 17, ladite première mâchoire 15 n'étant pas forcement montée avec la portion centrale. Il est donc nécessaire d'avoir une étape de fixation de la première mâchoire 15 à la portion principale.In the case of a first jaw 15 which is not made of material with the rod, an optional step (visible at figure 14c ) consists of the attachment of the first jaw to the main portion is achieved. In fact, in this case, the spacer device kit comprises a central portion, a first jaw 15 and a second jaw 17, said first jaw 15 not necessarily being mounted with the central portion. It is therefore necessary to have a step of fixing the first jaw 15 to the main portion.

Une autre étape optionnelle (non représentée) pour les deux manières de pose d'un isolant consiste à désassembler la seconde mâchoire 17 de la première mâchoire 15. En effet, le kit du dispositif d'entretoisement comprend une portion centrale, une première mâchoire 15 et une seconde mâchoire 17, ladite seconde mâchoire 17 pouvant être préfixée à la première mâchoire 15.Another optional step (not shown) for the two ways of installing an insulation consists in disassembling the second jaw 17 from the first jaw 15. In fact, the spacer device kit comprises a central portion, a first jaw 15. and a second jaw 17, said second jaw 17 being able to be prefixed to the first jaw 15.

Le procédé de fonctionnement c'est-à-dire d'accouplement des deux mâchoires 15, 17 et des moyens d'accouplage 19 est le suivant.The method of operation, that is to say of coupling the two jaws 15, 17 and the coupling means 19 is as follows.

Ainsi, une première étape, visible aux figures 14d, 14e et 14f, consiste à se munir de la membrane M et à la placer sur la première mâchoire 15. La membrane M est avantageusement une membrane d'étanchéité à l'air et/ou de gestion de la vapeur d'eau, de préférence une membrane M assurant à la fois ces deux fonctions. La membrane de gestion de la vapeur d'eau est avantageusement une membrane pare-vapeur ou une membrane hygrorégulante, c'est-à-dire dont la perméance à la vapeur d'eau varie en fonction de l'humidité relative ambiante. La membrane M est constituée d'une feuille ou d'une pluralité de feuilles assemblées ensemble. Ce placement de la membrane M sur la première mâchoire 15 est tel que la membrane M est posée sur la face de la première mâchoire 15 opposée à la face par laquelle ladite première mâchoire 15 est attachée à la portion centrale.Thus, a first step, visible to figures 14d, 14e and 14f , consists in taking the membrane M and placing it on the first jaw 15. The membrane M is advantageously an airtight membrane and / or water vapor management, preferably a membrane M ensuring both these functions. The water vapor management membrane is advantageously a vapor barrier or a hygroregulating membrane, that is to say the permeance of water vapor varies as a function of the ambient relative humidity. The membrane M consists of a sheet or a plurality of sheets assembled together. This placement of the membrane M on the first jaw 15 is such that the membrane M is placed on the face of the first jaw 15 opposite to the face by which said first jaw 15 is attached to the central portion.

Dans une seconde étape visible aux figures 14g, 14h et 14i, les deux demi-mâchoires 170 sont assemblées entre elles pour former la seconde mâchoire 17 et sont accouplées à la première mâchoire 15.In a second step visible to figures 14g , 2 p.m. and 2 p.m. , the two half-jaws 170 are assembled together to form the second jaw 17 and are coupled to the first jaw 15.

Selon une première façon, les deux demi-mâchoires 170 sont assemblées entre elles avant d'être accouplées à la première mâchoire 15 et verrouillée. Cette première façon est très pratique dans le cas de demi-machoires 170 munies d'un système de charnière 185. En effet, dans cette première façon, les demi-mâchoires 170 sont solidaires l'une de l'autre avant d'être accouplées à la première mâchoire 15. Cet accouplement est, lui, réalisé simultanément au verrouillage des deux demi-mâchoires 170 entre elles.According to a first way, the two half-jaws 170 are assembled together before being coupled to the first jaw 15 and locked. This first way is very practical in the case of half-jaws 170 provided with a hinge system 185. In fact, in this first way, the half-jaws 170 are integral with one another before being coupled. to the first jaw 15. This coupling is itself carried out simultaneously with the locking of the two half-jaws 170 between them.

Selon une seconde façon, cette seconde étape est opérée pour que l'assemblage des demi-mâchoires 170 en une seconde mâchoire 17, leur verrouillage et l'accouplage de cette seconde mâchoire avec la première mâchoire soient simultanées. On comprend ainsi que l'opérateur ne fait qu'une opération pour assembler les deux demi-mâchoires 170 entre elles, les verrouiller et pour accoupler ces demi-mâchoires 170 à la première mâchoire 15.According to a second way, this second step is carried out so that the assembly of the half-jaws 170 into a second jaw 17, their locking and the coupling of this second jaw with the first jaw are simultaneous. It is thus understood that the operator only performs one operation for assemble the two half-jaws 170 together, lock them and to couple these half-jaws 170 to the first jaw 15.

En effet, cette seconde étape consiste à se munir des deux demi-mâchoires 170. Puis, les demi-mâchoires 170 sont manipulées pour former la seconde mâchoire 17 en faisant en sorte que les parties saillantes des demi-machoires présentant une surface complémentaire secondaire 192 puisse coopérer avec la surface complémentaire primaire 191.Indeed, this second step consists in providing the two half-jaws 170. Then, the half-jaws 170 are manipulated to form the second jaw 17 by ensuring that the projecting parts of the half-jaws having a secondary complementary surface 192 can cooperate with the primary complementary surface 191.

Dans le cas du premier exemple, la seconde étape consiste à assembler les deux demi-mâchoires 170 tout en insérant la première mâchoire 15 dans l'espace E, de chaque demi-mâchoire 170, entre la portion inclinée 174b s'étendant orthogonalement à l'axe de la portion centrale et la surface de la demi mâchoire 170.In the case of the first example, the second step consists in assembling the two half-jaws 170 while inserting the first jaw 15 in the space E, of each half-jaw 170, between the inclined portion 174b extending orthogonally to the 'axis of the central portion and the surface of the half jaw 170.

Dans le cas du second exemple, la seconde étape consiste à assembler les deux demi-mâchoires 170 tout en insérant le relief 194 de la partie saillante de chaque demi-mâchoire 170 dans la gorge 193 agencée sur la paroi latérale de la première mâchoire 15.In the case of the second example, the second step consists in assembling the two half-jaws 170 while inserting the relief 194 of the projecting part of each half-jaw 170 in the groove 193 arranged on the side wall of the first jaw 15.

Dans le cas du troisième exemple, la seconde étape consiste à assembler les deux demi-mâchoires 170 tout en insérant la première mâchoire 15 dans le logement formé par la partie saillante 1720, 1721 munie de la surface inclinée et la surface de la demi-mâchoire 170 à partir de laquelle cette partie saillante s'étend.In the case of the third example, the second step consists in assembling the two half-jaws 170 while inserting the first jaw 15 in the housing formed by the projecting part 1720, 1721 provided with the inclined surface and the surface of the half-jaw. 170 from which this protruding part extends.

Dans ce cas, la membrane, précédemment posée sur la première mâchoire 15, vient s'intercaler entre la surface complémentaire primaire 191 de la première mâchoire et la surface complémentaire secondaire 192 de la seconde mâchoire. Ce calage de la membrane entre la première mâchoire 15 et la seconde mâchoire 17 a pour conséquence de permettre la fixation et le maintien de ladite membrane.In this case, the membrane, previously placed on the first jaw 15, is inserted between the primary complementary surface 191 of the first jaw and the secondary complementary surface 192 of the second jaw. This wedging of the membrane between the first jaw 15 and the second jaw 17 has the consequence of allowing said membrane to be fixed and held in place.

Astucieusement, cette configuration des mâchoires 15, 17 permet de maintenir la membrane sans causer de rupture d'intégrité. En effet, la membrane est ici coincée entre les deux mâchoires dans que les surfaces complémentaires ne percent ladite membrane.Cleverly, this configuration of the jaws 15, 17 makes it possible to maintain the membrane without causing any rupture of integrity. Indeed, the membrane is here wedged between the two jaws in that the complementary surfaces do not pierce said membrane.

Dans une première variante, la première mâchoire 15 et la seconde mâchoire 17 sont telles qu'elles présentent une géométrie circulaire. Cette géométrique circulaire s'applique prioritairement à la première mâchoire. En particulier, cette géométrie circulaire s'applique à la forme de la paroi latérale 151 de la première mâchoire 15 sur laquelle les demi-mâchoires 170 viennent s'agencer et à la (aux) zone(s) formant la surface complémentaire.In a first variant, the first jaw 15 and the second jaw 17 are such that they have a circular geometry. This circular geometry applies primarily to the first jaw. In particular, this circular geometry applies to the shape of the side wall 151 of the first jaw 15 on which the half-jaws 170 come to fit and to the zone (s) forming the complementary surface.

Dans le cas du premier et du troisième exemple de réalisation, la forme, sensiblement, circulaire de la paroi latérale permet à elle seule une liberté angulaire pour l'assemblage des deux mâchoires. En effet, la forme circulaire permet à l'opérateur d'installer les deux demi-mâchoires 170 sans contrainte de position angulaire comme visible à la figure 15. La figure 16 représente une première mâchoire 15 dont la forme est, sensiblement circulaire, ou octogonale.In the case of the first and third exemplary embodiments, the substantially circular shape of the side wall alone allows angular freedom for the assembly of the two jaws. Indeed, the circular shape allows the operator to install the two half-jaws 170 without constraint of angular position as visible at the figure 15 . The figure 16 shows a first jaw 15, the shape of which is substantially circular or octagonal.

Dans le cas d'une première mâchoire munie d'un décrochement, si la partie haute sert pour l'assemblage des deux mâchoires alors la partie haute et/ou la partie basse sont circulaires.In the case of a first jaw provided with a recess, if the upper part is used for the assembly of the two jaws then the upper part and / or the lower part are circular.

Dans le cas du second exemple, la gorge 193 dans laquelle le relief 194 de la surface complémentaire secondaire 192 s'insère s'étend sur la périphérie de la paroi latérale 151', cette paroi latérale est circulaire.In the case of the second example, the groove 193 in which the relief 194 of the secondary complementary surface 192 is inserted extends over the periphery of the side wall 151 ', this side wall is circular.

Dans le cas d'un décrochement sur la première mâchoire, si la partie porte ladite gorge alors au moins la partie haute est circulaire. Si la gorge est agencée sur la partie basse alors la partie haute et la partie basse sont circulaires.In the case of a recess on the first jaw, if the part bears said groove then at least the upper part is circular. If the groove is arranged on the lower part then the upper part and the lower part are circular.

Dans une seconde variante visible à la figure 17, les demi-mâchoires 170 sont agencées pour que la partie saillante 172 de chaque demi-mâchoire 170 épouse la forme de la paroi latérale formant la surface complémentaire primaire. En effet, avoir une partie saillante 172 qui s'étend de façon rectiligne sur la largeur de la demi-mâchoire 170 permet de maintenir la membrane M. Toutefois, si la paroi latérale 151 formant la surface complémentaire primaire est circulaire, alors la partie saillante ne permet pas un maintien optimal. Astucieusement selon la seconde variante, la partie saillante 172 est agencée pour s'étendre selon une forme telle que la surface complémentaire secondaire et la surface complémentaire primaire s'emboitent parfaitement. Cette variante permet avantageusement d'avoir la totalité de la surface complémentaire secondaire qui est utile pour le maintien de la membrane et pour l'accouplage de la seconde mâchoire à la première mâchoire.In a second variant visible at figure 17 , the half-jaws 170 are arranged so that the projecting part 172 of each half-jaw 170 matches the shape of the side wall forming the primary complementary surface. Indeed, having a protruding part 172 which extends rectilinearly over the width of the half-jaw 170 makes it possible to maintain the membrane M. However, if the side wall 151 forming the primary complementary surface is circular, then the protruding part does not provide optimal support. Cleverly according to the second variant, the projecting part 172 is arranged to extend in a shape such that the secondary complementary surface and the primary complementary surface fit together perfectly. This variant advantageously makes it possible to have all of the secondary complementary surface which is useful for maintaining the membrane and for coupling the second jaw to the first jaw.

Dans une troisième variante non représentée, la première mâchoire 15 comprend deux demi-mâchoires. Cette variante est appliquée dans le cas d'une mâchoire qui vient se fixer à la portion centrale.In a third variant not shown, the first jaw 15 comprises two half-jaws. This variant is applied in the case of a jaw which is fixed to the central portion.

Ces deux demi-mâchoires de la première mâchoire 15 coopèrent l'une avec l'autre pour former ladite première mâchoire 15. La fixation se fait par l'intermédiaire de moyens d'assemblage. Ces moyens d'assemblage peuvent prendre différentes formes pour permettre aux demi-mâchoires de la première mâchoire 15 de s'assembler.These two half-jaws of the first jaw 15 cooperate with one another to form said first jaw 15. The fixing is effected by means of assembly means. These assembly means can take different forms to allow the half-jaws of the first jaw 15 to come together.

Selon un premier exemple, les deux demi-mâchoires sont assemblées l'une à l'autre par vissage. Les demi-mâchoires sont agencées pour permettre à une vis d'assembler les deux demi-mâchoires.According to a first example, the two half-jaws are assembled together by screwing. The half-jaws are arranged to allow a screw to assemble the two half-jaws.

Selon un second exemple, les deux demi-mâchoires sont assemblées l'une à l'autre par encliquetage. Pour cela, une des demi-mâchoires comprend au moins une lame déformable munie d'un cran alors que l'autre mâchoire comprend un logement. La lame déformable est apte à se déformer pour entrer ou sortir du logement, ce dernier comprenant une encoche dans laquelle le cran s'insère.According to a second example, the two half-jaws are assembled together by snap-fastening. For this, one of the half-jaws comprises at least one deformable blade provided with a notch while the other jaw comprises a housing. The deformable blade is able to deform to enter or leave the housing, the latter comprising a notch into which the notch fits.

Dans une alternative des deux exemples, les deux les deux demi-mâchoires sont solidaires par une charnière. Cette charnière peut être une bande de matière déformable ou un système de gond et penture.In an alternative of the two examples, the two of the two half-jaws are secured by a hinge. This hinge can be a strip of deformable material or a hinge and hinge system.

Dans une autre variante visible aux figures 18 et 19, les deux demi-mâchoires 170 formant la seconde mâchoire 17 sont agencés pour permettre la fixation d'une ossature. Pour cela, des moyens de fixation d'une ossature 30 sont agencés Ces moyens de fixation 30 sur agencés sur la face supérieure d'au moins une demi-mâchoire 170. Ces moyens 30 consistent, par exemple, en une rainure 31 pouvant être périphérique ou en deux portions parallèles agencés sur la seconde mâchoire permettant la fixation d'un profilé P en U. en effet, un tel profilé consiste en une feuille métallique ou plastique ou polymère pliée pour avoir deux bras parallèles permettant d'obtenir une forme en U ou C selon l'orientation dudit profilé. L'extrémité de chaque bras du profilé présente une surépaisseur. Cette surépaisseur est telle qu'elle peut s'insérer dans la rainure pour permettre la fixation dudit profilé.In another variant visible to figures 18 and 19 , the two half-jaws 170 forming the second jaw 17 are arranged to allow the fixing of a framework. For this, means for fixing a frame 30 are arranged These fixing means 30 on arranged on the upper face of at least one half-jaw 170. These means 30 consist, for example, of a groove 31 which may be peripheral. or in two parallel portions arranged on the second jaw allowing the fixing of a U-shaped P-section. in fact, such a section consists of a metal or plastic or polymer sheet folded to have two parallel arms making it possible to obtain a U-shape or C depending on the orientation of said section. The end of each arm of the profile has an extra thickness. This extra thickness is such that it can be inserted into the groove to allow the fixing of said profile.

Alternativement, les moyens de fixation d'une ossature comprennent deux bras parallèles 33. Ces bras s'étendent depuis la seconde mâchoire 17 dans une direction parallèle à l'axe de la portion centrale. Ces bras ont un écartement tel qu'ils peuvent s'insérer dans l'espace présente entre les deux bras d'un profilé en U ou C.Alternatively, the means for fixing a frame comprise two parallel arms 33. These arms extend from the second jaw 17 in a direction parallel to the axis of the central portion. These arms have a spacing such that they can fit into the space between the two arms of a U or C section.

Bien entendu, la présente invention ne se limite pas à l'exemple illustré mais est susceptible de diverses variantes et modifications qui apparaîtront à l'homme de l'art.Of course, the present invention is not limited to the example illustrated but is susceptible of various variants and modifications which will appear to those skilled in the art.

En effet, si les moyens d'accouplage 19 selon l'invention permettent d'assembler la première mâchoire 15 et la seconde mâchoire 17 pour le maintien une membrane à un dispositif d'entretoisement sans risque de rupture d'intégrité de la membrane, il apparait que ces moyens d'accouplage 19 utilisant surfaces complémentaires primaires 191 et secondaires 192 sont utilisables pour un dispositif d'entretoisement dans lequel la tige 12 perce la membrane.Indeed, if the coupling means 19 according to the invention make it possible to assemble the first jaw 15 and the second jaw 17 for maintaining a membrane to a spacer device without risk of breaking the integrity of the membrane, it appears that these coupling means 19 using complementary primary surfaces 191 and secondary 192 can be used for a device spacer in which the rod 12 pierces the membrane.
