Description

La présente invention concerne un corps de coffre destiné à réceptionner une pièce de jonction entre un linteau et un dormant de menuiserie.The present invention relates to a trunk body for receiving a connecting piece between a lintel and a frame of a joiner.

Un corps de coffre est un accessoire destiné à être implanté dans une habitation au-dessus d'un ouvrant, tel qu'une fenêtre, une porte. Un occultant est monté dans le corps de coffre pour pourvoir être descendu devant l'ouvrant.A trunk body is an accessory intended to be implanted in a house above an opening, such as a window, a door. An occultant is mounted in the trunk body to be able to be lowered in front of the opening.

Un tel corps de coffre est formé d'un profilé, généralement de section en U retourné, considéré dans sa position de pose et dans lequel prend place l'occultant. Le corps de coffre est ainsi délimité par une paroi de voûte prolongée de ses deux bords longitudinaux par deux parois latérales tournées en vis-à-vis et qui délimitent entre elles l'évidement pour l'occultant.Such a trunk body is formed of a profile, generally U-shaped section returned, considered in its position of installation and in which takes place the occultant. The trunk body is thus delimited by an extended arch wall of its two longitudinal edges by two side walls turned vis-à-vis and which delimit between them the recess for the occultant.

Il est également connu par exemple de FR 2992017 A1 ou de EP 2985404 A1 d'utiliser au moins une pièce de jonction conjointement à un corps de coffre pour lier mécaniquement un linteau avec la traverse haute d'un dormant de menuiserie pour lier mécaniquement le linteau avec ladite traverse haute afin de la rigidifier. On connaît ainsi un corps de coffre dont une paroi latérale, destinée à être tournée vers l'intérieur de l'habitation, est creusée, depuis sa face externe, d'une rainure. La pièce de jonction, constituée d'une patte métallique peut prendre place dans ladite rainure pour relier un linteau coulé sur la paroi de voûte et la traverse haute du dormant d'une menuiserie et qui prend place sous ladite paroi latérale. La patte métallique présente, dans sa position de pose, une première branche verticale qui prend place dans la rainure, et qui est prolongée dans sa partie haute par une seconde branche qui s'étend horizontalement sur ou dans la paroi de voûte creusée alors d'une rainure horizontale, elle-même prolongée par une troisième branche qui s'étend vers le haut pour prendre ancrage dans le linteau. Le dormant peut ainsi être tenu fermement également dans sa partie haute.It is also known for example from FR 2992017 A1 or EP 2985404 A1 using at least one junction piece together with a trunk body to mechanically link a lintel with the top rail of a carpentry frame to mechanically link the lintel with said top rail to stiffen it. A trunk body is thus known, one side wall of which, intended to be turned towards the interior of the house, is hollowed out from its outer face by a groove. The joining piece, consisting of a metal lug can take place in said groove to connect a lintel sunk on the arch wall and the top rail of the frame of a carpentry and which takes place under said side wall. The metal tab has, in its position of installation, a first vertical branch which takes place in the groove, and which is extended in its upper part by a second branch which extends horizontally on or in the arch wall then dug out. a horizontal groove, itself extended by a third branch that extends upward to take anchor in the lintel. The frame can be held firmly also in its upper part.

Cette patte métallique est exposée à l'air ambiant de l'habitation et forme un pont thermique captant par temps froid des calories dans l'habitation pour les évacuer dans le mur.This metal leg is exposed to the ambient air of the house and forms a thermal bridge capturing in cold weather calories in the house to evacuate in the wall.

Considérant cet état de fait, le demandeur a cherché une solution pour relier au travers d'un corps de coffre un linteau avec le dormant d'une menuiserie et qui ne forme pas de pont thermique.Considering this state of affairs, the applicant sought a solution to connect through a trunk body a lintel with the frame of a carpentry and which does not form a thermal bridge.

A cet effet, est proposé un corps de coffre délimité par un profilé présentant en section une géométrie en U retourné comprenant, une paroi de voûte prolongée à ses deux bords longitudinaux respectivement par deux parois latérales, qui s'étendent dans la même direction et perpendiculairement ou de manière quasi perpendiculaire à la paroi de voûte, ces trois parois délimitant entre elles un évidement longitudinal pour réceptionner un occultant. Selon l'invention, une première rainure transversale traverse au moins localement la paroi de voûte et ladite première rainure transversale se raccorde avec une seconde rainure creusant transversalement une paroi latérale, depuis sa face interne.For this purpose, is proposed a trunk body delimited by a profile having in section a U-shaped geometry returned, including a vault wall extended at its two longitudinal edges respectively by two side walls, which extend in the same direction and perpendicularly or almost perpendicular to the arch wall, these three walls delimiting between them a longitudinal recess for receiving an occultant. According to the invention, a first transverse groove at least locally passes through the arch wall and said first transverse groove connects with a second groove transversely digging a side wall from its inner face.

Cette structure de corps de coffre est conçue pour réceptionner une pièce de jonction entre un linteau et un dormant de menuiserie qui peut ainsi prendre place dans la première rainure débouchante et dans la seconde rainure ouverte sur l'évidement, sans provoquer, à l'issue de l'implantation du corps de coffre dans une habitation, de pont thermique.This trunk body structure is designed to receive a connecting piece between a lintel and a carpentry frame which can thus take place in the first groove opening and in the second groove open on the recess, without causing, at the end the implantation of the body of chest in a house, thermal bridge.

Selon une caractéristique additionnelle de l'invention, le corps de coffre incorpore une pièce de jonction délimitée par une première branche, une seconde branche qui prolonge de manière quasi perpendiculaire et à son extrémité haute, dans la position de montage de la pièce de jonction, ladite première branche, la première branche prenant place dans la seconde rainure, la seconde branche prenant place dans la première rainure et la seconde branche étant pourvue d'un moyen d'ancrage dans un linteau.According to an additional feature of the invention, the trunk body incorporates a junction part defined by a first branch, a second branch which extends almost perpendicularly and at its upper end, in the mounting position of the connecting piece, said first branch, the first branch taking place in the second groove, the second branch taking place in the first groove and the second branch being provided with an anchoring means in a lintel.

La première branche de la pièce de jonction demeure masquée dans ladite paroi latérale, elle n'est ainsi pas exposée à l'air ambiant de l'habitation. Elle ne forme pas de pont thermique. La seconde branche demeure masquée sous le linteau.The first branch of the joining piece remains hidden in said side wall, it is thus not exposed to the ambient air of the house. It does not form a thermal bridge. The second branch remains hidden under the lintel.

Selon une caractéristique additionnelle de l'invention, la première branche est reliée à la seconde branche, par l'intermédiaire d'une paroi concave, tournée vers l'intérieur de ladite pièce de jonction.According to an additional feature of the invention, the first leg is connected to the second leg, via a concave wall, facing the inside of said connecting piece.

La pièce de jonction disposée dans le corps de coffre ne pénètre pas dans l'évidement du corps de coffre.The junction piece disposed in the trunk body does not penetrate the recess of the trunk body.

Selon une caractéristique additionnelle de l'invention, le moyen d'ancrage est formé d'au moins une patte d'ancrage qui se raccorde sur la seconde branche, dans une direction opposée à celle de la première branche, ladite patte d'ancrage faisant saillie à l'extérieur du corps de coffre au travers de sa paroi de voûte.According to an additional characteristic of the invention, the anchoring means is formed of at least one anchoring tab which is connected to the second branch, in a direction opposite to that of the first branch, said anchoring tab making protruding outside the trunk body through its arch wall.

Ainsi, en coulant un linteau sur la paroi de voûte du corps de coffre, on solidarise la pièce de jonction dans le linteau.Thus, by casting a lintel on the vault wall of the trunk body, the connecting piece is secured in the lintel.

Selon une caractéristique additionnelle de l'invention, le moyen d'ancrage est formé de deux pattes d'ancrage.According to an additional feature of the invention, the anchoring means is formed of two anchoring tabs.

Le corps de coffre pourvu de sa pièce de jonction offre une capacité de résistance accrue à un couple exercé sur l'extrémité libre de la première branche, autour des deux pattes d'ancrage.The trunk body provided with its junction piece provides increased resistance to a torque exerted on the free end of the first branch, around the two anchors.

Selon une caractéristique additionnelle de l'invention, les deux pattes d'ancrage forment entre elles un angle ouvert de quelques degrés.According to an additional characteristic of the invention, the two anchoring tabs form between them an open angle of a few degrees.

L'insert peut être utilisé pour servir de point d'ancrage à la traverse haute du dormant.The insert can be used to anchor the top cross member of the frame.

Selon une caractéristique additionnelle de l'invention, la pièce de jonction est constituée par un assemblage de plusieurs éléments.According to an additional feature of the invention, the joining piece is constituted by an assembly of several elements.

Il devient possible de monter la pièce de jonction au travers de l'évidement du corps de coffre, par un assemblage de ses éléments, pour poser une pièce de jonction oubliée, pour monter des pièces de jonction dans un corps de coffre de type rénovation.It becomes possible to mount the joining piece through the recess of the trunk body, by an assembly of its elements, to put a junction piece forgotten, to mount connecting parts in a trunk body renovation type.

Selon une caractéristique additionnelle de l'invention, la première branche est assemblée à la seconde branche au niveau de la paroi concave.According to an additional feature of the invention, the first branch is assembled to the second branch at the concave wall.

On peut monter la seconde branche dans le corps de coffre, puis assembler la première branche avec la seconde.The second branch can be mounted in the trunk body, and then the first branch assembled with the second branch.

Selon une caractéristique additionnelle de l'invention, ladite ou chaque patte d'ancrage est formée d'une embase solidaire de la seconde branche et d'un embout fixé à l'extrémité de ladite embase.According to an additional feature of the invention, said or each anchor tab is formed of a base integral with the second branch and a nozzle attached to the end of said base.

L'embout ou les embouts peuvent être démontés pendant le transport ou le stockage des corps de coffre.The end piece or the end pieces can be dismantled during transport or storage of the trunk bodies.

En variante de réalisation, ladite ou chaque patte d'ancrage est formée d'une embase solidaire de la seconde branche, ladite ou chaque patte d'ancrage étant traversée radialement par un trou de passage pour monter un tire-fond d'ancrage dans un linteau.In an alternative embodiment, said or each anchor tab is formed of a base integral with the second branch, said or each anchor tab being traversed radially by a through hole for mounting an anchor bolt in a lintel.

On peut alors monter le corps de coffre et sa ou ses pattes de jonction sur un linteau existant.It is then possible to assemble the trunk body and its junction lug (s) on an existing lintel.

Selon une caractéristique additionnelle de l'invention, l'assemblage des éléments est réalisé par une jonction de type queue d'aronde.According to an additional feature of the invention, the assembly of the elements is achieved by a dovetail type junction.

L'assemblage de deux éléments destinés à coopérer est réalisé par simple rapprochement latéral.The assembly of two elements intended to cooperate is achieved by simple lateral approach.

Selon une caractéristique additionnelle de l'invention, la largeur de la seconde rainure est plus grande que la largeur de la première rainure transversale ou l'inverse, permettant un assemblage des éléments de la pièce de jonction à l'intérieur du corps de coffre.According to an additional feature of the invention, the width of the second groove is greater than the width of the first transverse groove or vice versa, allowing an assembly of the elements of the connecting piece inside the trunk body.

On peut réaliser l'assemblage de la pièce de jonction depuis l'intérieur du corps de coffre, en plaçant les deux branches de la pièce de jonction dans leurs rainures respectives.It is possible to assemble the junction piece from inside the trunk body, by placing the two branches of the junction piece in their respective grooves.

Selon une caractéristique additionnelle de l'invention, la profondeur et la largeur de la première rainure transversale qui traverse la paroi de voûte sont limitées localement, du côté opposé à la seconde rainure, de sorte qu'un talon est formé dans ladite paroi de voûte pour supporter localement la branche horizontale afin de caler convenablement la pièce de jonction.According to an additional characteristic of the invention, the depth and the width of the first transverse groove which crosses the arch wall are limited locally, on the opposite side to the second groove, so that a heel is formed in said arch wall to locally support the horizontal branch to properly wedge the connecting piece.

Le corps de coffre 100 présenté sur la Fig. 1 est destiné à contenir un occultant pour une porte ou une fenêtre, tel qu'un volet roulant, un store, une moustiquaire. Le corps de coffre 100 présente en section une géométrie en U retourné dans sa position d'utilisation. Il est fabriqué de préférence dans un matériau isolant d'un point de vue thermique et suffisamment résistant d'un point de vue mécanique. Il est avantageusement fabriqué en polystyrène, dans un moule de fabrication.The chest body 100 presented on the Fig. 1 is intended to contain a blackout for a door or window, such as a shutter, a blind, a mosquito net. The trunk body 100 has in section a U-shaped geometry returned to its position of use. It is preferably manufactured in a thermally insulating material and sufficiently resistant from a mechanical point of view. It is advantageously made of polystyrene in a production mold.

En section transversale, le corps de coffre 100 est délimité par une paroi de voûte Pv prolongée à ses deux bords longitudinaux respectivement par deux parois latérales Pl2 et Pl2, communément appelées parois de jambage, qui s'étendent dans la même direction et perpendiculairement ou de manière quasi perpendiculaire à la paroi de voûte Pv. Ces trois parois délimitent entre elles un évidement longitudinal Ev pour réceptionner un occultant pour une porte, pour une fenêtre.In cross section, the trunk body 100 is delimited by a vault wall Pv extended at its two longitudinal edges respectively by two side walls P12 and P12, commonly called jamb walls, which extend in the same direction and perpendicularly or from almost perpendicular to the vault wall Pv. These three walls delimit between them a longitudinal recess Ev to receive an occultant for a door, for a window.

Deux joues de fermeture, non représentées, peuvent être apposées sur les deux faces latérales du corps de coffre pour tenir, lorsque l'occultant est un volet roulant, les deux extrémités de l'axe dudit volet roulant.Two closing cheeks, not shown, can be affixed to both side faces of the trunk body to hold, when the blackout is a shutter, the two ends of the axis of said shutter.

Un profilé de rigidification Pf est monté à chevauchement sur le bord longitudinal libre de chaque paroi latérale Pl. Il est fabriqué préférentiellement en métal, tel qu'un alliage d'aluminium. Il présente une géométrie en U qui recouvre le bord libre d'une paroi de jambage Pl.A stiffening profile Pf is mounted to overlap on the free longitudinal edge of each side wall P1. It is preferably made of metal, such as an aluminum alloy. It has a U-shaped geometry that covers the free edge of a jamb wall Pl.

Sur la Fig. 2, une première rainure transversale Rn1 traverse, au moins localement, l'épaisseur de la paroi de voûte Pv du corps de coffre. Elle s'étend depuis la paroi latérale Pl1 jusqu'à pratiquement l'autre paroi latérale Pl2.On the Fig. 2 , a first transverse groove Rn1 passes through, at least locally, the thickness of the vault wall Pv of the trunk body. It extends from the side wall P1 to virtually the other side wall P12.

Au-dessus du corps de coffre est présentée une pièce de jonction 200 destinée à relier un linteau avec le dormant d'une menuiserie. La pièce de jonction 200 est présentée dans une position d'introduction dans la première rainure transversale Rn1, suggérée par la flèche F.Above the chest body is presented a connecting piece 200 for connecting a lintel with the frame of a joinery. The joining piece 200 is presented in an insertion position in the first transverse groove Rn1, suggested by the arrow F.

Sur la Fig. 3, la première rainure transversale Rn1 qui traverse la paroi de voûte Pv se raccorde à une seconde rainure Rn2 qui creuse transversalement, c'est-à-dire verticalement dans la position de pose du corps de coffre 100, la paroi latérale Pl1, depuis sa face interne Fi. La seconde rainure Rn2 n'est, de préférence, pas débouchante du côté de la face externe de la paroi latérale Pl1.On the Fig. 3 , the first transverse groove Rn1 which passes through the arch wall Pv is connected to a second groove Rn2 which is transversely hollow, that is to say vertically in the laying position of the trunk body 100, the side wall P1, since its internal face Fi. The second groove Rn2 is preferably not open on the side of the outer face of the side wall P1.

La première rainure transversale Rn1 ainsi que la seconde rainure Rn2 forment une réservation pour loger la pièce de jonction.The first transverse groove Rn1 and the second groove Rn2 form a reservation for accommodating the joining piece.

Sur la Fig. 2, la pièce de jonction 200 est constituée d'un composant monolithique, c'est-à-dire fabriqué en un seul tenant. Elle est fabriquée dans un matériau relativement rigide, par exemple en métal. Son épaisseur est de préférence constante, par exemple voisine de 10 mm. Elle peut ainsi être fabriquée par découpage dans une plaque de tôle. Elle présente globalement en vue de face une géométrie en L, considérée dans sa position de pose, comprenant une première branche Bv verticale prolongée de son bord haut par une seconde branche Bh horizontale.On the Fig. 2 the joining piece 200 consists of a monolithic component, that is to say, made in one piece. It is made of a relatively rigid material, for example metal. Its thickness is preferably constant, for example close to 10 mm. It can thus be manufactured by cutting into a sheet metal plate. It generally presents in front view an L-shaped geometry, considered in its laying position, comprising a first vertical branch Bv extended from its top edge by a second horizontal branch Bh.

Un moyen d'ancrage, tel qu'au moins une patte d'ancrage Dc se raccorde cependant par le haut sur la seconde branche horizontale Bh, c'est-à-dire dans une direction opposée à la première branche Bv. Deux pattes d'ancrage Dc1 et Dc2 se raccordent, sur cette Fig. 2, sur la branche horizontale Bh. L'une se raccorde vers le milieu de ladite branche horizontale Bh et l'autre prolonge de manière quasi perpendiculaire son extrémité libre. On remarque cependant que les deux pattes d'ancrage forment entre elles un angle ouvert de quelques degrés, notamment compris entre 4 et 30 degrés et dont le plan médian est de préférence perpendiculaire à ladite branche horizontale.An anchoring means, such as at least one anchoring tab Dc, however, is connected from above to the second horizontal branch Bh, that is to say in a direction opposite to the first branch Bv. Two anchors Dc1 and Dc2 are connected on this Fig. 2 , on the horizontal branch Bh. One connects to the middle of said horizontal branch Bh and the other extends substantially perpendicular to its free end. Note however that the two anchors form between them an open angle of a few degrees, in particular between 4 and 30 degrees and whose median plane is preferably perpendicular to said horizontal branch.

Sur la Fig. 4, la pièce de jonction 200 est montée dans le corps de coffre 100. La branche verticale Bv prend place dans la seconde rainure verticale Rn2 alors que la branche horizontale Bh prend place dans la première rainure Rn1 qui traverse la paroi de voûte Pv. Les deux pattes Dc1 et Dc2 font saillie par le dessus de la paroi de voûte Pv. Le montage de la pièce de jonction 200 est réalisé par insertion de celle-ci au travers de la première rainure Rn1 et de l'extérieur vers l'intérieur du coffre.On the Fig. 4 , the connecting piece 200 is mounted in the trunk body 100. The vertical leg Bv takes place in the second vertical groove Rn2 while the horizontal leg Bh takes place in the first groove Rn1 through the arch wall Pv. The two legs Dc1 and Dc2 protrude from the top of the arch wall Pv. The junction piece 200 is mounted by inserting the latter through the first groove Rn1 and from the outside towards the inside of the box.

Lorsque l'occultant est un volet roulant dont le tablier est enroulé, déroulé autour d'un tambour d'enroulement, l'évidement Ev présente, sous la paroi de voûte, une géométrie semi-circulaire, comme cela est visible sur les Figs. 1, 2 et 3. Sur la Fig. 2, la branche verticale Bv est reliée à la branche horizontale Bh, par l'intermédiaire d'une paroi concave Pa, tournée vers l'intérieur de la pièce de jonction et qui reprend pratiquement le rayon de l'évidement Ev sous la paroi de voûte. Cela apparaît distinctement sur la Fig. 4, où l'on voit la paroi concave Pa, qui présente ici une géométrie arrondie, pour ne pas empiéter sur le volume d'enroulement du tablier. Dans la même logique, la largeur de la branche verticale Bv est pratiquement la même que la profondeur de la seconde rainure verticale Rn2. La pièce de jonction 200 n'empiète alors pas dans le volume de l'évidement destiné à réceptionner un occultant.When the blackout is a rolling shutter whose apron is wound, unrolled around a winding drum, the recess Ev presents, under the arch wall, a semicircular geometry, as is visible on the Figs. 1 , 2 and 3 . On the Fig. 2 the vertical branch Bv is connected to the horizontal branch Bh, via a concave wall Pa, facing the inside of the joining piece and which substantially takes up the radius of the recess Ev under the arch wall . This appears distinctly on the Fig. 4 , where we see the concave wall Pa, which here has a rounded geometry, not to encroach on the winding volume of the deck. In the same logic, the width of the vertical branch Bv is substantially the same as the depth of the second vertical groove Rn2. The junction piece 200 does not encroach into the volume of the recess for receiving an occultant.

Sur la Fig. 3, on remarque que la profondeur et la largeur de la première rainure Rn1 qui traverse la paroi de voûte Pv sont limitées localement, du côté opposé à la seconde rainure Rn2, si bien qu'un talon Tl est formé dans la paroi de voûte Pv pour supporter localement la branche horizontale de la pièce de jonction, permettant, conjointement avec la seconde rainure Rn2, un positionnement précis de ladite pièce de jonction dans le corps de coffre 100. Par ailleurs, la hauteur de ce talon Tl s'étend jusqu'au rayon de l'évidement Ev sous la paroi de voûte, ce qui permet d'éviter que la branche horizontale de la pièce de jonction ne pénètre dans l'évidement du corps de coffre. Cela apparaît distinctement sur la Fig. 4. En prévoyant un talon relativement peu large, il est envisageable de pouvoir monter la pièce de jonction depuis l'intérieur du corps de coffre, c'est-à-dire au travers de son évidement Ev.On the Fig. 3 it is noted that the depth and the width of the first groove Rn1 which passes through the vault wall Pv are limited locally, on the opposite side to the second groove Rn2, so that a heel T1 is formed in the vault wall Pv for locally support the horizontal leg of the connecting piece, allowing, together with the second groove Rn2, a precise positioning of said junction piece in the trunk body 100. Furthermore, the height of the heel Tl extends to radius of the recess Ev under the arch wall, which prevents the horizontal branch of the connecting piece does not enter the recess of the trunk body. This appears distinctly on the Fig. 4 . By providing a relatively small heel, it is conceivable to be able to mount the connecting piece from inside the trunk body, that is to say through its recess Ev.

Ainsi, et en référence à la Fig. 5, la pièce de jonction 200 qui est montée dans le corps de coffre 100, permet de relier un linteau Lt avec un dormant Dt. La pièce de jonction 200 qui demeure disposée à l'intérieur du corps de coffre 100 n'est pas en mesure de capter des calories dans l'habitation. Elle ne forme alors pas de pont thermique.So, and with reference to the Fig. 5 , the connecting piece 200 which is mounted in the trunk body 100, makes it possible to connect a lintel Lt with a frame Dt. The junction piece 200 which remains disposed inside the trunk body 100 is not able to to capture calories in the home. It does not form a thermal bridge.

Le linteau Lt est coulé consécutivement à l'implantation du corps de coffre 100 dans une habitation, au-dessus de l'embrasure d'une porte ou d'une fenêtre. Il est coulé sur la paroi de voûte Pv dans un coffrage délimité au-dessus du corps de coffre. La présence de deux pattes d'ancrage Dc1 et Dc2 offre un ancrage relativement résistant dans le linteau. En effet, le vent, le fonctionnement de la ventilation mécanique, conduisent à exposer en pression ou en dépression la porte, la fenêtre, tenue dans le dormant Dt. Dans ces conditions, et du fait que la contrainte exercée par le dormant Dt sur la pièce de jonction 200 au niveau du profilé Pf1, forme un couple mécanique autour des deux pattes d'ancrage Dc, l'une d'elles travaille en traction et l'autre travaille en compression ou inversement. Les deux pattes Dc ne sont pas de préférence disposées parallèlement l'une à l'autre, elles forment entre elles un angle aigu de quelques degrés pour encore renforcer leur efficacité d'ancrage.The lintel Lt is sunk following the implantation of the trunk body 100 in a dwelling, above the doorway of a door or window. It is cast on the Pv arch wall in a formwork delimited above the trunk body. The presence of two anchors Dc1 and Dc2 provides a relatively strong anchorage in the lintel. Indeed, the wind, the operation of mechanical ventilation, lead to expose in pressure or depression the door, the window, held in the frame Dt. In these conditions, and because the stress exerted by the frame Dt on the connecting piece 200 at the profile Pf1, forms a pair mechanical around the two anchors Dc, one of them works in tension and the other works in compression or vice versa. The two tabs Dc are preferably not arranged parallel to one another, they form between them an acute angle of a few degrees to further enhance their anchoring efficiency.

Le dormant Dt comprend une traverse haute Th et avec laquelle est liée directement ou indirectement l'extrémité inférieure de la branche verticale Bv de la pièce de jonction 200 et par l'intermédiaire d'un moyen de liaison.The frame Dt comprises a high cross Th and with which is directly or indirectly connected the lower end of the vertical branch Bv of the connecting piece 200 and via a connecting means.

Plus précisément et sur la Fig. 4, l'extrémité libre de la branche verticale Bv pénètre dans un insert St et qui est noyé dans l'extrémité de la paroi latérale Pl1, pendant la fabrication du corps de coffre 100. Sur la vue en détail présentée sur cette même Fig. 4, cet insert St présente en section une géométrie rectangulaire ou carrée, dont la largeur est pratiquement la même que celle de la paroi latérale Pl1 et il est traversé, au moins localement, d'un passage central Pc dans lequel se monte l'extrémité libre de la branche verticale Bv. L'insert St est retenu prisonnier dans le profilé de rigidification Pf1 à l'issue de la pose dudit profilé sur le bord libre de la paroi latérale Pl1. L'insert St est fabriqué dans un matériau qui présente un coefficient de conductivité thermique relativement faible, pour éviter que la pièce de jonction 200 ne capte des calories dans le profilé Pf1. Le passage central peut ne pas être débouchant pour éviter que l'extrémité libre de la branche verticale Bv ne vienne toucher le profilé Pf1, afin d'éviter que la pièce de jonction 200 ne forme un pont thermique. Dans le même but et avec un passage central débouchant, la longueur de la branche verticale Bv est calculée pour que son extrémité libre ne vienne pas toucher le profilé Pf1.More precisely and on the Fig. 4 the free end of the vertical branch Bv enters an insert St and which is embedded in the end of the side wall P1, during the manufacture of the trunk body 100. On the view in detail presented on this same Fig. 4 , this insert St has in section a rectangular or square geometry, whose width is substantially the same as that of the side wall P1 and is traversed, at least locally, a central passage Pc in which is mounted the free end of the vertical branch Bv. The insert St is held prisoner in the stiffening profile Pf1 at the end of the laying of said profile on the free edge of the side wall Pl1. The insert St is made of a material that has a relatively low coefficient of thermal conductivity, to prevent the junction piece 200 does not capture calories in the Pf1 profile. The central passage may not be opening to prevent the free end of the vertical branch Bv comes to touch the profile Pf1, to prevent the joining piece 200 does not form a thermal bridge. For the same purpose and with a central passage opening, the length of the vertical branch Bv is calculated so that its free end does not come touch the profile Pf1.

On remarquera que l'extrémité libre de la branche verticale Bv est décalée vers l'extérieur de la pièce de jonction 200, par l'intermédiaire d'une courte portion oblique afin de pouvoir être disposée globalement dans le milieu de la paroi latérale Pl1 et pouvoir pénétrer le passage central de l'insert St. La seconde rainure Rn2 est creusée en conséquence.It will be noted that the free end of the vertical leg Bv is shifted outwardly from the junction piece 200, via a short oblique portion so that it can be arranged generally in the middle of the side wall P1 and ability to penetrate the central passage of the insert St. The second groove Rn2 is hollowed out accordingly.

Sur la Fig. 5, cet insert St est relié mécaniquement au linteau Lt par l'intermédiaire de la pièce de jonction 200. Il est avantageusement utilisé pour servir de point d'ancrage à la traverse haute du dormant Dt. On peut ainsi utiliser dans ce but, une patte de fixation Pt de section en L, dont l'aile verticale vient prendre appui sur le profilé Pf1 et dont l'aile horizontale vient prendre appui sur la traverse haute Th ou sur une aile constitutive du profilé Pf1 mis en appui sur ladite traverse haute. La patte Pt est avantageusement fixée par vissage dans l'insert St et préférentiellement aussi dans la traverse haute Th. On utilise une telle patte de fixation pour des largeurs de tableau relativement importantes. On remarquera que cette patte de liaison n'est pas indispensable. On peut encore, en effet, fixer directement le profilé Pf1 sur la traverse haute Th, par exemple par l'intermédiaire d'une aile constitutive du profilé Pf1, comme cela apparaît sur la Fig. 8.On the Fig. 5 , this insert St is mechanically connected to the lintel Lt via the junction piece 200. It is advantageously used to serve as anchor point to the upper cross member of the frame Dt. One can thus use for this purpose, a tab Fixing Pt section L, whose vertical flange comes to bear on the profile Pf1 and whose horizontal flange bears on the high Th cross or on a constituent wing of the profile Pf1 placed in abutment on said high crossbar. The tab Pt is advantageously fixed by screwing in the insert St and preferably also in the high cross Th. Such a fastening tab is used for relatively large table widths. Note that this link is not essential. It is still possible, in fact, to directly fix the profile Pf1 on the high crossbar Th, for example by means of a constituent wing of the profile Pf1, as it appears on FIG. Fig. 8 .

Sur la Fig. 6, on constate que la pièce de jonction 200 est constituée d'un assemblage de plusieurs éléments. Sur cette Fig. 6, la branche verticale Bv est réunie à la branche horizontale Bh au niveau de la paroi concave Pa. Par ailleurs, chaque patte d'ancrage Dc est constituée d'une embase Em qui prend racine sur la branche horizontale Bh et d'un embout Bt qui prolonge ladite embase. Un autre embout peut prolonger l'embout Bt pour prendre ancrage dans un chaînage de section en U destiné à former un linteau et qui est relativement profond.On the Fig. 6 it is found that the joining piece 200 consists of an assembly of several elements. On this Fig. 6 , the vertical branch Bv is joined to the horizontal branch Bh at the concave wall Pa. Moreover, each anchoring tab Dc consists of a base Em which takes root on the horizontal branch Bh and a mouthpiece Bt. which extends said base. Another tip may extend the Bt end for anchoring in a U-section to form a lintel and which is relatively deep.

L'assemblage mutuel de ces éléments est réalisé, sur cette Fig. 6, par une jonction du type à queue d'aronde permettant un assemblage de deux éléments à abouter par rapprochement latéral comme le suggère la flèche F2.The mutual assembly of these elements is realized, on this Fig. 6 , by a junction of the dovetail type allowing an assembly of two elements to abut by lateral approach as suggested by the arrow F2.

Sur la Fig. 7, cette pièce de jonction 200 en plusieurs éléments est montée dans un corps de coffre 100. On remarque que la hauteur de la branche horizontale Bh est inférieure à la hauteur de la paroi de voûte Pv mesurée sous l'évidement Ev, si bien que les embases Em, relativement courtes, dépassent à peine de la face supérieure de la paroi de voûte Pv, comme cela apparaît sur cette Fig. 7. Ainsi, il est possible de superposer des corps de coffre pour minimiser leur volume de stockage en statique ou pendant leur transport. Les embouts Bt constitutifs des pattes d'ancrage sont assemblés avec les embases Em sur le site de pose du corps de coffre 100.On the Fig. 7 this connecting piece 200 in several elements is mounted in a trunk body 100. It is noted that the height of the horizontal leg Bh is less than the height of the arch wall Pv measured under the recess Ev, so that the Em bases, relatively short, barely exceed the upper face of the vault wall Pv, as it appears on this Fig. 7 . Thus, it is possible to superpose trunk bodies to minimize their static storage volume or during transport. The Bt bits constituting the anchoring lugs are assembled with the Em bases on the site of installation of the trunk body 100.

Par ailleurs, l'assemblage des éléments de la pièce de jonction 200 peut être réalisé par l'intérieur du corps de coffre 100, c'est-à-dire dans son évidement Ev. Cette situation peut exister lorsqu'on a oublié de monter une pièce de jonction dans le corps de coffre. La largeur de la seconde rainure Rn2 est, dans ce cas, plus grande que la largeur de la première rainure Rn1 ou l'inverse, permettant un assemblage des éléments de la pièce de jonction 200 à l'intérieur du corps de coffre.Furthermore, the assembly of the elements of the joining piece 200 can be achieved by the interior of the trunk body 100, that is to say in its recess Ev. This situation may exist when one has forgotten to assemble a connecting piece in the trunk body. The width of the second groove Rn2 is, in this case, greater than the width of the first groove Rn1 or vice versa, allowing an assembly of the elements of the junction piece 200 inside the trunk body.

Une autre situation où le montage de la pièce de jonction en plusieurs éléments par l'intérieur du corps de coffre peut présenter un intérêt est la suivante. Le corps de coffre de l'invention peut encore être posé en réhabilitation sur un linteau existant, comme cela est montré sur la Fig. 8. Dans cette variante de réalisation de la pièce de jonction 200, ses deux embases Em sont plus courtes pour ne pas faire saillie au-delà de la paroi de voûte. Elles sont traversées radialement et respectivement de deux trous de passage Tp, symbolisés par des traits d'axes, pour monter des tire-fonds destinés à prendre ancrage dans le linteau. En accroissant la hauteur de la branche horizontale Bh pour atteindre la hauteur de la paroi de voûte Pv mesurée sous l'évidement Ev, les embases Em peuvent disparaître. Les deux trous de passage Tp traversent alors la branche horizontale Bh.Another situation where the assembly of the junction piece into several elements by the inside of the trunk body may be of interest is as follows. The body of chest of the invention can still be placed in rehabilitation on an existing lintel, as shown on the Fig. 8 . In this embodiment of the joining piece 200, its two bases Em are shorter so as not to project beyond the arch wall. They are traversed radially and respectively two holes Tp passage, symbolized by lines of axes, to mount lag bolts for anchoring in the lintel. By increasing the height of the horizontal leg Bh to reach the height of the arch wall Pv measured under the recess Ev, Em bases can disappear. The two passage holes Tp then cross the horizontal branch Bh.

Par ailleurs le démontage du corps de coffre demeure possible en toutes circonstances.Moreover, the dismantling of the trunk body remains possible in all circumstances.

Le corps de coffre 100 de l'invention peut réceptionner en interne une pièce de jonction 200 destinée à relier un linteau avec le dormant d'une menuiserie. La pièce de jonction demeurant masquée dans le corps de coffre à l'issue de son implantation, elle ne génère pas de pont thermique.The trunk body 100 of the invention can internally receive a junction piece 200 for connecting a lintel with the frame of a joinery. The junction piece remains hidden in the trunk body after its implementation, it does not generate a thermal bridge.

Aucune sur épaisseur ne vient modifier la face externe de la paroi de jambage qui masque la pièce de jonction.None on thickness does change the outer face of the jamb wall that hides the joining piece.

L'insertion de la pièce de jonction 200 dans le corps de coffre 100 se fait, soit par le dessus du corps de coffre, en le faisant passer au travers de sa paroi voûte, soit par l'intérieur du corps de coffre au travers de son évidement.The insertion of the junction piece 200 in the trunk body 100 is done either by the top of the trunk body, by passing it through its arched wall, or by the inside of the trunk body through its recess.
