Description

La présente invention se rapporte à un dispositif de fixation destiné à fixer une têtière sur un montant de menuiserie métallique.The present invention relates to a fastening device for fixing a headrest on a metalworking jamb.

Les menuiseries métalliques présentent deux montants parallèles, l'un est destiné à être monté articulé tandis que l'autre présente des éléments de verrouillage. Ainsi, ce dernier présente un chant et deux ailes rigides étendues à distance l'une de l'autre en saillie dudit chant pour former un espace libre longitudinal entre lesdites deux ailes rigides. Cet espace longitudinal est destiné à recevoir les éléments de verrouillage et en particulier une serrure, des pênes et des tringles de commande de ces pênes. Les ailes rigides présentent chacune un bord libre et une nervure longitudinale qui s'étend sensiblement parallèlement audit bord libre. Les nervures longitudinales desdites ailes rigides s'étendent en regard l'une de l'autre à l'intérieur dudit espace libre longitudinal. La têtière est par exemple profilée en U et elle présente des perçages et des évidements de passage des pênes. Elle est installée sur lesdites ailes entre lesdits bords libres pour refermer ledit espace longitudinal et recouvrir notamment la serrure, les tringles et les pênes. Les dispositifs de fixation des têtières connus comprennent des vis insérées dans les perçages, et ces vis sont vissées dans des éléments d'ancrage montés dans le fond de l'espace longitudinal ou à travers le chant par exemple. Le serrage des vis permet de maintenir en position fixe la têtière contre les nervures et entre les ailes rigides du montant.The metal joinery have two parallel uprights, one is intended to be articulated while the other has locking elements. Thus, the latter has a song and two rigid wings extended at a distance from one another projecting from said edge to form a longitudinal free space between said two rigid wings. This longitudinal space is intended to receive the locking elements and in particular a lock, bolts and control rods of these bolts. The rigid wings each have a free edge and a longitudinal rib which extends substantially parallel to said free edge. The longitudinal ribs of said rigid wings extend facing one another within said longitudinal free space. The headrest is for example U-shaped and has holes and recesses passage bolts. It is installed on said wings between said free edges to close said longitudinal space and cover in particular the lock, the rods and bolts. Known headrest fixing devices comprise screws inserted in the holes, and these screws are screwed into anchoring elements mounted in the bottom of the longitudinal space or through the edge for example. The tightening of the screws makes it possible to maintain in fixed position the headrest against the ribs and between the rigid wings of the upright.

Le problème posé par ces menuiseries métalliques, réside dans leur conductivité thermique et dans leur difficulté de montage. En effet, les matériaux métalliques étant généralement conducteur de la chaleur, il est malaisé d'isoler thermiquement deux espaces l'un de l'autre avec de telle menuiserie. Aussi, il a notamment été imaginé d'engager les têtières, généralement en inox, dans un fourreau en matière plastique, ce qui permet d'isoler thermiquement et au moins partiellement les deux ailes rigides du montant. En outre, le montant est constitué de deux éléments métalliques profilés assemblés l'un avec l'autre au moyen de matériaux peu conducteurs de la chaleur. En revanche, les éléments de solidarisation et les éléments d'ancrage métalliques conduisent la chaleur, et nuisent par conséquent aux propriétés d'isolation globales de la menuiserie. De plus, l'ajustage de la têtière entre les deux ailes rigides est relativement malaisé et nécessite d'engager les vis directement à l'aveugle dans des taraudages.The problem posed by these metal joineries, lies in their thermal conductivity and in their difficulty of assembly. Indeed, metal materials being generally heat conductor, it is difficult to thermally isolate two spaces from each other with such carpentry. Also, it has in particular been imagined to engage the headrests, usually stainless steel in a plastic sleeve, which thermally isolates and at least partially the two rigid wings of the amount. In addition, the amount consists of two profiled metal elements assembled with each other by means of materials that conduct little heat. On the other hand, the fastening elements and the metal anchoring elements conduct the heat, and therefore harm the overall insulation properties of the joinery. In addition, the adjustment of the headrest between the two rigid wings is relatively difficult and requires to engage the screws directly to the blind in threads.

Aussi, un problème qui se pose et que vise à résoudre la présente invention est de fournir un dispositif de fixation pour fixer les têtières de manière aisée, et qui permette aussi d'isoler thermiquement les montants de menuiserie métallique.Also, a problem that arises and that aims to solve the present invention is to provide a fixing device for fixing the headrests easily, and which also allows thermal insulation of the amounts of metal joinery.

Dans le but de résoudre ce problème, et selon un premier objet, la présente invention propose un dispositif de fixation pour fixer une têtière sur un montant de menuiserie métallique, ledit montant de menuiserie métallique présentant un chant et deux ailes rigides étendues à distance l'une de l'autre en saillie dudit chant pour former un espace libre longitudinal entre lesdites deux ailes rigides, lesdites ailes rigides présentant chacune un bord libre et une nervure longitudinale s'étendant sensiblement parallèlement audit bord libre, les nervures longitudinales desdites ailes rigides s'étendant en regard l'une de l'autre à l'intérieur dudit espace libre longitudinal en formant respectivement un bord de retenue orienté à l'opposé dudit bord libre, ladite têtière étant destinée à être installée sur lesdites ailes entre lesdits bords libres pour refermer ledit espace longitudinal, ledit dispositif de fixation comprenant un élément d'ancrage destiné à être ancré entre lesdites ailes rigides et des moyens de solidarisation destinés à être engagés dans ledit élément d'ancrage en traversant ladite têtière pour maintenir ladite têtière contre lesdites ailes rigides. Selon l'invention, ledit élément d'ancrage comprend une pièce profilée en U réalisée dans un matériau thermiquement isolant et présentant deux ailes flexibles sensiblement parallèles entre elles, ladite pièce profilée en U présentant un épaulement formant deux portées d'appui sensiblement parallèles respectivement sur les faces opposées desdites ailes flexibles ; et lesdites ailes sont mobiles entre une position rapprochée l'une de l'autre dans laquelle ledit élément d'ancrage est apte à être engagé entre lesdites nervures et une position écartée l'une de l'autre dans laquelle lesdites portées d'appui viennent respectivement en prise sur lesdits bords de retenue desdites nervures.In order to solve this problem, and according to a first object, the present invention proposes a fastening device for fixing a headrest on a metal joinery post, said metal joinery post having a singing and two rigid wings extended at a distance. one of the other protruding from said edge to form a longitudinal free space between said two rigid wings, said rigid wings each having a free edge and a longitudinal rib extending substantially parallel to said free edge, the longitudinal ribs of said rigid wings s' extending facing each other within said longitudinal free space, respectively forming a retaining edge oriented away from said free edge, said headrest being intended to be installed on said wings between said free edges to close again said longitudinal space, said fixing device comprising an anchoring element intended to be anchored between said rigid wings and securing means intended to be engaged in said anchor element through said headrest to maintain said headrest against said rigid wings. According to the invention, said anchoring element comprises a profiled U-shaped piece made of a thermally insulating material and having two flexible wings substantially parallel to each other, said U-shaped piece having a shoulder forming two substantially parallel bearing surfaces respectively on the opposite faces of said flexible wings; and said wings are movable between a position close to one another in which said anchoring element is able to be engaged between said ribs and a position spaced apart from each other in which said bearing spans come from respectively engaged on said retaining edges of said ribs.

Ainsi, une caractéristique de l'invention réside dans la mise en oeuvre d'une pièce profilée en U isolante thermiquement, relativement aux matériaux métalliques, et qui vient en prise dans les nervures sans transmettre la chaleur d'une aile rigide vers l'autre. De la sorte, lorsque les deux profilés prolongés respectivement par leur aile rigide et qui forment le montant de menuiserie, sont isolés l'un de l'autre au niveau du chant, il n'y a alors aucun pont thermique ni entre les deux ailes ni entre les deux profilés. De la sorte, l'isolation thermique au niveau du montant est assurée.Thus, a feature of the invention lies in the implementation of a thermally insulating U shaped profile piece, relative to metallic materials, and which engages in the ribs without transmitting heat. from one rigid wing to the other. In this way, when the two sections extended respectively by their rigid wing and which form the amount of woodwork, are isolated from each other at the edge, there is then no thermal bridge or between the two wings neither between the two sections. In this way, the thermal insulation at the level of the amount is ensured.

Avantageusement, ladite pièce profilée en U présente un fond et une partie médiane de réception desdits moyens de solidarisation solidaire dudit fond et qui s'étend entre lesdites ailes flexibles. De la sorte, la pièce profilée en U est susceptible d'être engagée entre les deux ailes rigides, le fond de la pièce profilée en U en regard du chant du montant de la menuiserie, et la partie ouverte, vers l'extérieur de l'espace libre longitudinal à l'opposé du chant. En outre, ladite partie médiane de réception présente, de préférence, un orifice sensiblement perpendiculaire auxdites portées d'appui, ledit orifice étant destiné à recevoir lesdits moyens de solidarisation. Aussi, ces derniers sont destinés, d'un côté à être verrouillés à travers ledit orifice, à l'intérieur de la partie médiane, et de l'autre côté, à venir s'appliquer sur la têtière qu'ils traversent, pour maintenir cette dernière en appui à force contre les nervures par exemple.Advantageously, said U-shaped piece has a bottom and a median receiving portion of said securing means integral with said bottom and extending between said flexible wings. In this way, the U-shaped piece is likely to be engaged between the two rigid wings, the bottom of the U-shaped piece opposite the edge of the amount of the joinery, and the open part, outwardly of the longitudinal free space opposite the singing. In addition, said median receiving portion preferably has an orifice substantially perpendicular to said bearing surfaces, said orifice being intended to receive said securing means. Also, these are intended, on one side to be locked through said orifice, inside the middle part, and on the other side, to come to apply on the headrest they cross, to maintain the latter in force support against the ribs for example.

Selon un mode de réalisation avantageux, ladite pièce profilée en U présente deux chemins de passage respectivement entre lesdites ailes flexibles et ladite partie médiane, lesdits chemins de passage s'étendant sensiblement parallèlement auxdites portées d'appui, de manière à permettre de loger la ou les tringles de commande des pênes précisément, entre la têtière et la pièce profilée en U.According to an advantageous embodiment, said profiled U-shaped piece has two paths of passage respectively between said flexible wings and said middle part, said passageways extending substantially parallel to said bearing surfaces, so as to make it possible to house the or the control rods of the bolts precisely, between the headrest and the U-shaped piece.

Selon un mode de mise en oeuvre de l'invention particulièrement avantageux, ladite pièce profilée en U est moulée d'une seule pièce en matière plastique. Elle est par exemple obtenue par extrusion puis par découpe en section. Ainsi, elle est réalisée à un coût avantageux. En outre, grâce à la nature du matériau, la matière plastique, par exemple un polymère du type polyamide, les ailes sont élastiquement flexibles. De la sorte, lorsque la pièce profilée en U est engagée entre les nervures, les ailes flexibles sont alors rapprochées l'une de l'autre à force et dès que la pièce est en position et que les ailes flexibles sont relâchées, elles retrouvent leur position originelle, écartée l'une de l'autre de sorte que les portées d'appui viennent en prise contre les bords de retenue de ces nervures. Cette caractéristique permet un montage rapide et aisé de la pièce profilée en U, comme on l'expliquera plus en détail ci-après.According to a particularly advantageous embodiment of the invention, said U-shaped piece is molded in one piece of plastics material. It is for example obtained by extrusion and then by cutting in section. Thus, it is performed at an advantageous cost. In addition, thanks to the nature of the material, the plastic material, for example a polymer of the polyamide type, the wings are elastically flexible. In this way, when the U-shaped piece is engaged between the ribs, the flexible wings are then brought closer to one another by force and as soon as the piece is in position and the flexible wings are released, they return to their position. original position, separated from each other so that the bearing spans engage against the retaining edges of these ribs. This feature allows a quick and easy mounting of the U-shaped piece, as will be explained in more detail below.

En outre, ladite pièce profilée en U présente avantageusement une saignée s'étendant dans ledit fond sensiblement parallèlement auxdites ailes flexibles, ladite saignée débouchant à l'opposée de ladite partie médiane, de manière à diminuer la résistance au rapprochement des deux ailes flexibles l'une vers l'autre lors de l'engagement de la pièce profilée en U entre les nervures. De plus, lesdites ailes flexibles présentent respectivement une bordure libre, et lesdits moyens de solidarisation sont engagés dans ledit élément d'ancrage, entre lesdites bordures libres.In addition, said profiled U-shaped piece advantageously has a groove extending in said bottom substantially parallel to said flexible flanges, said groove opening at the opposite of said middle portion, so as to reduce the resistance to approaching the two flexible flanges. towards each other when the U-shaped piece is engaged between the ribs. In addition, said flexible wings respectively have a free edge, and said securing means are engaged in said anchoring element, between said free edges.

Par ailleurs, lesdites faces opposées desdites ailes flexibles présentent des parois inclinées formant rampes, à l'opposé desdites bordures libres par rapport auxdites portées d'appui, de manière à pouvoir engager la pièce profilée en U de manière à ce que les parois inclinées viennent s'appuyer entre les nervures et ensuite à enfoncer la pièce profilée en U vers le chant de façon que les parois inclinées soient entraînées en frottement contre les nervures, et tendent à rapprocher l'une de l'autre des ailes flexibles. Ainsi, lorsque le décrochement franchit entièrement les nervures, les ailes flexibles sont rappelées élastiquement et s'écartent l'une de l'autre de sorte que les portées d'appui viennent en regard des bords de retenue des nervures.Furthermore, said opposite faces of said flexible wings have inclined walls forming ramps, opposite said free edges with respect to said bearing surfaces, so as to engage the U-shaped piece so that the inclined walls come resting between the ribs and then pushing the U-shaped piece towards the edge so that the inclined walls are driven in friction against the ribs, and tend to move towards one another of the flexible wings. Thus, when the recess completely crosses the ribs, the flexible wings are resiliently biased and move away from each other so that the bearing surfaces are opposite the retaining edges of the ribs.

De la sorte, la pièce profilée en U est susceptible d'être pré-montée avec la têtière et les moyens de solidarisation, et ensuite d'être clipsée entre les ailes rigides, ce qui facilite grandement le montage de la têtière. Avantageusement, lesdits moyens de solidarisation comportent des éléments vissables aptes à être vissés dans ladite pièce profilée en U, il suffit alors après le clipsage, de visser les éléments vissables et alors, ces derniers prennent appui sur la têtière tandis que la pièce profilée en U vient en prise contre les bords de retenue des nervures. Ainsi, la têtière est prise en étau entre les moyens de solidarisation et les ailes rigides sur lesquelles elle s'appuie. Préférentiellement, la têtière est profilée en U, et les ailes de la têtière viennent en appui sur les bords des nervures opposées au bord de retenue.In this way, the profiled U-shaped piece is likely to be pre-assembled with the headrest and the securing means, and then to be clipped between the rigid wings, which greatly facilitates the mounting of the headrest. Advantageously, said securing means comprise screw elements capable of being screwed into said profiled U-shaped piece, it is sufficient then after clipping, to screw the screwable elements and then, the latter bear on the headrest while the U-shaped piece engages the retaining edges of the ribs. Thus, the headrest is gripped between the securing means and the rigid wings on which it is supported. Preferably, the headrest is U-shaped, and the wings of the headrest bear against the edges of the ribs opposite the retaining edge.

Selon un autre objet, la présente invention concerne un montant de menuiserie métallique équipé d'une têtière, ledit montant présentant un chant et deux ailes rigides étendues à distance l'une de l'autre en saillie dudit chant pour former un espace libre longitudinal entre lesdites deux ailes rigides, lesdites ailes rigides présentant chacune un bord libre et une nervure longitudinale s'étendant sensiblement parallèlement audit bord libre, les nervures longitudinales desdites ailes rigides s'étendant en regard l'une de l'autre à l'intérieur dudit espace libre longitudinal en formant respectivement un bord de retenue orienté à l'opposé dudit bord libre, ladite têtière étant destinée à être installée sur lesdites ailes entre lesdits bords libres pour refermer ledit espace longitudinal ; selon cet autre objet, le montant de menuiserie métallique comprend un dispositif de fixation telle que défini ci-dessus selon le premier objet.According to another object, the present invention relates to an amount of metal joinery equipped with a headrest, said amount having a singing and two rigid wings extended at a distance from one another projecting from said edge to form a longitudinal free space between said two rigid wings, said rigid wings each having a free edge and a longitudinal rib extending substantially parallel to said free edge, the longitudinal ribs of said rigid wings extending facing one another within said longitudinal free space, respectively forming a retaining edge oriented away from said free edge, said headrest being intended to be installed on said wings between said free edges to close said longitudinal space; according to this other object, the amount of metal joinery comprises a fixing device as defined above according to the first object.

D'autres particularités et avantages de l'invention ressortiront à la lecture de la description faite ci-après d'un mode de réalisation particulier de l'invention, donné à titre indicatif mais non limitatif, en référence aux dessins annexés sur lesquels :

  • la Figure 1 est une vue schématique de profil d'un mécanisme de serrure incluant le dispositif de fixation conforme à l'invention;
  • la Figure 2 est une vue schématique de détail en coupe droite selon le plan II-II illustré sur la Figure 1 du dispositif de fixation; et,
  • la Figure 3 est une vue schématique partielle en perspective du dispositif de fixation représentée sur la Figure 2.
Other features and advantages of the invention will emerge on reading the following description of a particular embodiment of the invention, given by way of indication but not limitation, with reference to the accompanying drawings in which:
  • the Figure 1 is a schematic side view of a lock mechanism including the fastening device according to the invention;
  • the Figure 2 is a schematic detail view in cross-section along plane II-II illustrated on the Figure 1 the fastening device; and,
  • the Figure 3 is a partial schematic perspective view of the fixing device shown in FIG. Figure 2 .

La Figure 1 illustre en vue de profil, un mécanisme de serrure incluant un boîtier 10, une têtière filante 12 appliquée sur la tranche du boîtier 10 et quatre pêne, un pêne demi-tour 14, un pêne dormant 16, un pêne bas 18 et un pêne haut 20. En outre, est représenté partiellement sur cette Figure 1, le montant de menuiserie métallique 22 à l'intérieur duquel sont installés tous les éléments précités.The Figure 1 illustrates in profile view, a lock mechanism including a housing 10, a shooting headrest 12 applied to the edge of the housing 10 and four bolts, a latch bolt 14, a dead bolt 16, a low bolt 18 and a high bolt 20. In addition, is partially represented on this Figure 1 , the amount of metal joinery 22 inside which are installed all the aforementioned elements.

On retrouve ainsi en coupe droite, sur la Figure 2, le montant de menuiserie métallique 22 constitué de deux profilés métalliques en regard, un profilé métallique externe 24 et un profilé métallique interne 26. Les deux profilés métalliques 24, 26 sont maintenus en position fixe l'un par rapport à l'autre au moyen de deux profils longitudinaux en matériau composite, l'un 28 formant avec les retours respectifs 30, 32 des profilés métalliques externe 24 et interne 26, un chant 34 du montant de menuiserie métallique 22, l'autre 36 à l'opposé, refermant le montant de menuiserie métallique 22. Ces deux profils longitudinaux 28, 36 en matériau composite, par exemple un matériau polymère chargé de fibre, permettent de rompre la conduction thermique entre les deux profilés métalliques externe 24 et interne 26.We thus find in straight section, on the Figure 2 , the amount of metal joinery 22 consists of two metal profiles facing each other, an external metal section 24 and an internal metal section 26. The two metal sections 24, 26 are held in a fixed position relative to each other by means of of two longitudinal profiles of composite material, one 28 forming with the respective returns 30, 32 external metal profiles 24 and inner 26, one edge 34 of the amount of metal joinery 22, the other 36 to the opposite, closing the amount of metal joinery 22. These two longitudinal profiles 28, 36 of composite material, for example a fiber-filled polymer material, can break the heat conduction between the two outer metal profiles 24 and inner 26.

En outre, le montant de menuiserie métallique 22 présente deux ailes rigides 38, 40 qui s'étendent à distance l'une de l'autre et parallèlement entre elles, en saillie du chant 34. Ces deux ailes rigides 38, 40 prolongent respectivement le profilé métallique externe 24 et le profilé métallique interne 26 et elles délimitent un espace libre longitudinal 42. Elles présentent également et respectivement un bord libre 44, 46 et une nervure 48, 50 qui s'étendent respectivement en saillie des ailes rigides 38, 40 et en regard l'une de l'autre à l'intérieur de l'espace libre longitudinal 42 et parallèlement aux bords libres 44, 46. Ces nervures 48, 50 présentent respectivement un bord de retenue 52, 54 orienté vers le chant 34 et à l'opposé un bord d'applique 56, 58 orienté vers l'extérieur de l'espace libre longitudinal 42.In addition, the amount of metal joinery 22 has two rigid wings 38, 40 which extend at a distance from each other and parallel to each other, projecting from the edge 34. These two rigid wings 38, 40 respectively extend the external metal section 24 and the internal metal section 26 and they define a longitudinal free space 42. They also have respectively a free edge 44, 46 and a rib 48, 50 which extend respectively projecting from the rigid wings 38, 40 and facing each other within the longitudinal free space 42 and parallel to the free edges 44, 46. These ribs 48, 50 respectively have a retaining edge 52, 54 oriented towards the edge 34 and the opposite an applied edge 56, 58 oriented towards the outside of the longitudinal free space 42.

Entre les ailes rigides est installé un dispositif de fixation 60 d'une têtière profilée en U 62, et entre la têtière profilée en U 62 et le dispositif de fixation 60, est montée à coulissement une tringle 63 que l'on décrira plus en détail en référence à la Figure 3. Cette tringle permet d'actionner les pênes haut 20 et bas 18 par l'intermédiaire de la serrure incluse dans le boîtier 10 représenté sur la Figure 1.Between the rigid wings is installed a fixing device 60 of a U-shaped headrest 62, and between the U-shaped headrest 62 and the fixing device 60, is slidably mounted a rod 63 which will be described in more detail with reference to the Figure 3 . This rod makes it possible to actuate the top and bottom bolts 18 by means of the lock included in the casing 10 shown in FIG. Figure 1 .

Ainsi, on va précisément décrire en référence à la Figure 3, le dispositif de fixation 60 conforme à l'invention. On retrouve sur cette Figure 3 la têtière profilée en U 62 et le dispositif de fixation comportant d'une part, un élément d'ancrage 64 et d'autre part, une vis de fixation 66.Thus, we will precisely describe with reference to the Figure 3 , the fixing device 60 according to the invention. We find on this Figure 3 the profiled U-shaped headrest 62 and the fixing device comprising, on the one hand, an anchoring element 64 and, on the other hand, a fixing screw 66.

L'élément d'ancrage 64 comprend une pièce profilée en U présentant un plan de symétrie axial P et un axe de symétrie A inclus dans ledit plan, ladite pièce étant réalisée à partir d'une section d'un profilé en matière plastique, par exemple en polyamide, et elle présente deux ailes flexibles 68, 70 opposées l'une de l'autre et parallèles entre elles. Ces deux ailes flexibles 68, 70 sont reliées entre elles par un fond 72 opposé à la partie ouverte de la pièce profilée en U. En outre, le fond 72 présente une partie médiane de réception 74 qui s'étend, à l'intérieur de la pièce profilée en U et en saillie dudit fond 72, entre les deux ailes flexibles 68, 70. Les deux ailes flexibles 68, 70 s'étendent parallèlement au plan de symétrie P, depuis le fond 72 jusqu'à une extrémité libre 80, 81.The anchoring element 64 comprises a U-shaped piece having an axial plane of symmetry P and an axis of symmetry A included in said plane, said part being made from a section of a plastic profile, by polyamide example, and it has two flexible wings 68, 70 opposite to each other and parallel to each other. These two flexible wings 68, 70 are interconnected by a bottom 72 opposite to the open part of the U-shaped piece. In addition, the bottom 72 has a median receiving portion 74 which extends inside the the profiled piece U and projecting from said bottom 72, between the two flexible wings 68, 70. The two flexible wings 68, 70 extend parallel to the plane of symmetry P, from the bottom 72 to a free end 80, 81.

Les ailes flexibles présentent deux faces opposées 76, 78, tandis que la pièce profilée en U présente, a mi-distance entre le fond 72 et les extrémités libres 80, 81, un épaulement ménageant deux portées d'appui opposées 82, 84. Ces deux portées d'appui 82, 84, orientées vers les extrémités libres 80, 81 et à l'opposé du fond 72, s'étendent parallèlement l'une par rapport à l'autre et selon la direction de l'axe de symétrie A. En outre, les deux faces opposées 76, 78 présentent respectivement une paroi inclinée 86, 88 par rapport au plan de symétrie axiale P, entre les portées d'appui respectives 82, 84 et le fonds 72. A l'opposé de ces parois inclinées 86, 88, par rapport aux portées d'appui respectives 82, 84, les deux faces opposées 76, 78 présentent des bordures libres opposées 87, 89 qui longent respectivement, les extrémités libres 80, 81. Les parois inclinées 86, 88 demeurent parallèles à l'axe de symétrie A de l'élément d'ancrage 64. Ainsi, cet élément d'ancrage 64 présente une faible largeur au niveau du fond 72, sensiblement inférieure à la distance qui sépare les deux nervures 48, 50 précitées, et il s'évase jusqu'aux portées d'appui 82, 84. On expliquera plus en détail dans la suite de la description, les avantages de ces caractéristiques. Par ailleurs, le fond 72 et la partie médiane de réception 64 présente une saignée axiale 90 coupée symétriquement par le plan de symétrie P et qui précisément débouche dans la partie de fond 72 et s'étend partiellement dans la partie médiane de réception 64. Cette dernière présente en outre un taraudage central 92 perpendiculaire à l'axe de symétrie A de l'élément d'ancrage 64 et qui présente, à l'une de ses extrémités, une intersection avec la saignée axiale 90, et à l'autre de ses extrémités, opposée au fond 72, une ouverture qui débouche au niveau des extrémités libres 80,81 des ailes flexibles 68, 70.The flexible wings have two opposite faces 76, 78, while the U shaped profile has, midway between the bottom 72 and the free ends 80, 81, a shoulder providing two opposite bearing surfaces 82, 84. These two bearing surfaces 82, 84, oriented towards the free ends 80, 81 and away from the bottom 72, extend parallel to one another and in the direction of the axis of symmetry A In addition, the two opposite faces 76, 78 respectively have an inclined wall 86, 88 with respect to the plane of axial symmetry P, between the respective bearing surfaces 82, 84 and the base 72. Opposite these walls inclined 86, 88, relative to the respective bearing surfaces 82, 84, the two opposite faces 76, 78 have opposite free edges 87, 89 which respectively follow the free ends 80, 81. The inclined walls 86, 88 remain parallel to the axis of symmetry A of the anchoring element 64. Ains i, this anchoring element 64 has a small width at the bottom 72, substantially less than the distance separating the two ribs 48, 50 mentioned above, and it flares up to the support bearing surfaces 82, 84. will explain in more detail in the rest of the description, the advantages of these characteristics. Furthermore, the bottom 72 and the median receiving portion 64 has an axial groove 90 cut symmetrically by the plane of symmetry P and which precisely opens into the bottom portion 72 and extends partially in the median receiving portion 64. the latter also has a central thread 92 perpendicular to the axis of symmetry A of the anchoring element 64 and which has, at one of its ends, an intersection with the axial groove 90, and the other of its ends, opposite the bottom 72, an opening which opens at the free ends 80, 81 of the flexible wings 68, 70.

De plus, la pièce profilée en U présente deux rainures parallèles axiales 94, 96 respectivement entre les ailes flexibles 68, 70 et la partie médiane de réception 74. Ces rainures parallèles axiales 94, 96 constituent deux chemins de passage parallèles de part et d'autre de la partie médiane de réception 74 et au niveau des bordures 87, 89.In addition, the profiled U-shaped piece has two axial parallel grooves 94, 96 respectively between the flexible wings 68, 70 and the median receiving portion 74. These axial parallel grooves 94, 96 constitute two parallel passage paths on both sides. other of the median receiving portion 74 and at the edges 87, 89.

La Figure 3 illustre en outre la tringle 63 dans laquelle est ménagé un évidement oblong 98 centrale qui s'étend longitudinalement en définissant alors deux parties de tringle opposées 100, 102 aptes à être montées à coulissement respectivement dans les rainures parallèles axiales 94, 96. Au surplus, on retrouve la têtière profilée en U 62 apte à venir coiffer les extrémités libres 80, 81 des ailes flexibles 68, 70 et dont les ailes de têtière sont destinées à venir respectivement en appui glissant sur les bordures libres opposées 87, 89. La têtière profilée en U 62 présente un orifice 104 apte à recevoir la vis de fixation 66 pour traverser ensuite l'évidement oblong 98 et être vissée à travers le taraudage central 92.The Figure 3 further illustrates the rod 63 in which is formed an oblong recess 98 central extending longitudinally defining then two opposite parts of the rod 100, 102 able to be slidably mounted respectively in the axial parallel grooves 94, 96. In addition, there is the profiled U-shaped headrest 62 capable of capping the free ends 80, 81 of the flexible wings 68, 70 and whose headrests are intended to come respectively in sliding abutment on the opposite free edges 87, 89. The U-shaped headrest 62 has an orifice 104 adapted to receive the fastening screw 66 to then pass through the oblong recess 98 and be screwed through the central thread 92.

Ainsi formé, l'ensemble constitué par la pièce profilée en U, la tringle 63, la têtière 62 et la vis de fixation 66 non totalement vissée à l'intérieur du taraudage central 92, est susceptible d'être clipsé entre les ailes rigides 38, 40 du montant de menuiserie métallique 22 tel que représenté sur la Figure 2. En effet, on vient tout d'abord appliquer l'ensemble précité entre les ailes rigides 38, 40 et plus précisément, les parois inclinées 86, 88 respectivement entre les nervures 50, 48 et sur lesquelles elles viennent prendre appui. En enfonçant encore à force l'ensemble précité vers le champ 34, les parois inclinées 86, 88 formes rampes et à mesure de l'enfoncement, les ailes flexibles 68, 70 se rapprochent l'une de l'autre. Elles y sont autorisées car d'une part, il existe un espace libre entre les ailes flexibles 68, 70 et la partie médiane de réception 74 et d'autre part il en existe un également délimitée par la saignée 90. Ainsi le rapprochement des ailes flexibles 68, 70 est-il facilité. Au fur et à mesure de l'enfoncement, les ailes flexibles 68, 70 se rapprochent l'une de l'autre en se déformant élastiquement, tandis que les espaces libres précités rétrécissent, et dès que l'épaulement arrive à un niveau situé en dessous des nervures 50, 48, vers le chant 34, les ailes flexibles 68, 70 s'écartent alors brusquement pour retrouver leur position initiale et partant, les portées d'appui 82, 84 viennent respectivement en regard des bords de retenue 52, 54 des nervures 48, 50.Thus formed, the assembly consisting of the U-shaped piece, the rod 63, the headrest 62 and the fixing screw 66 not completely screwed inside the central thread 92, can be clipped between the rigid flanges 38 , 40 of the amount of metal joinery 22 as shown on the Figure 2 . Indeed, it just first apply the aforementioned set between the rigid wings 38, 40 and more specifically, the inclined walls 86, 88 respectively between the ribs 50, 48 and on which they come to bear. By further forcing the aforementioned assembly towards the field 34, the inclined walls 86, 88 ramp forms and as the depression, the flexible wings 68, 70 are closer to each other. They are authorized because on the one hand, there is a free space between the flexible wings 68, 70 and the median receiving portion 74 and secondly there is one also delimited by the groove 90. Thus the approximation of the wings flexible 68, 70 is it easier. As and when depressed, the flexible wings 68, 70 come closer to each other by deforming elastically, while the aforementioned free spaces shrink, and as soon as the shoulder reaches a level located in below the ribs 50, 48, towards the edge 34, the flexible wings 68, 70 deviate then abruptly to find their initial position and thus, the bearing surfaces 82, 84 respectively come opposite the retaining edges 52, 54 ribs 48, 50.

De plus, les ailes de la têtière profilée en U 62 viennent en applique respectivement sur le bord d'applique 56, 58 des nervures 48, 50. Ensuite, la vis de fixation 66 qui est vissée plus complètement dans le taraudage central 92 provoque alors concomitamment, l'enfoncement de la pièce profilée en U dans la têtière profilée en U 62 et la mises en prise des portées d'appui 82, 84 contre le bord de retenue 52, 54, et tend à déformer sensiblement la partie médiane de réception 74 et le fond 72 et partant, à provoquer l'écartement plus encore des ailes flexibles 68, 70. Ainsi, cet effort latéral sensiblement perpendiculaire au plan de symétrie P, exercé sur les ailes flexibles 68, 70, les entraînent plus encore en appui à force contre les nervures 48, 50 et contribue à la solidarisation de l'élément d'ancrage entre les ailes rigides 38, 40. Au surplus, les bords des ailes de la têtière profilée en U 62 appliquées respectivement sur les bords d'applique 56, 58 sont entraînés à force contre ces bords d'applique. Ainsi, les ailes de la têtière profilée en U 62 et les portées d'appui 82, 84 forment respectivement étau et enserrent respectivement des nervures 48, 50. Le serrage à force de la vis de fixation 66 permet de la sorte de maintenir en position fixe, par l'intermédiaire des nervures 48, 50, la têtière profilée en U 62 et l'élément d'ancrage comprenant la pièce profilée en U.In addition, the wings of the U-shaped headrest 62 are respectively applied to the edge of the wall 56, 58 of the ribs 48, 50. Then, the fixing screw 66 which is screwed more completely into the central thread 92 then causes concomitantly, the depression of the U-shaped piece in the profiled U-shaped headrest 62 and the engagement of the bearing surfaces 82, 84 against the retaining edge 52, 54, and tends to substantially deform the middle receiving portion 74 and the bottom 72 and thus, to cause the separation even more flexible wings 68, 70. Thus, this lateral force substantially perpendicular to the plane of symmetry P, exerted on the flexible wings 68, 70, further drive them in force against the ribs 48, 50 and contributes to the joining of the anchoring element between the rigid wings 38, 40. In addition, the edges of the flanges of the U-shaped headrest 62 applied respectively to the edges of applied 56, 58 are forced against these edges of the applique. Thus, the wings of the profiled U-shaped headrest 62 and the bearing surfaces 82, 84 respectively form a vice and grip respectively ribs 48, 50. The force clamping of the fastening screw 66 allows in this way to maintain in position fixed, through the ribs 48, 50, the U-shaped headrest 62 and the anchoring element comprising the U-shaped piece.

On observera que la liaison entre les ailes rigides 38, 40 est réalisée par l'intermédiaire des nervures 48, 50 uniquement par la têtière profilée en U 62 qui est réalisé dans un matériau plastique isolant thermiquement, et par la pièce profilée en U 64, également réalisée dans un matériau plastique thermiquement isolant. Aussi, le transfert thermique par conduction entre le profilé métallique externe 24 le profilé métallique interne 26 est-il considérablement atténué.It will be observed that the connection between the rigid wings 38, 40 is achieved by means of the ribs 48, 50 only by the profiled U-shaped headrest 62 which is made of a thermally insulating plastic material, and by the U-profile piece 64, also made of a thermally insulating plastic material. Also, the heat transfer by conduction between the outer metal section 24 the inner metal section 26 is considerably attenuated.

Des dispositifs de fixation tels que définis ci-dessus, sont installés de proche en proche entre les ailes rigides 38, 40, par exemple au nombre de six, sur toute la longueur du montant de la menuiserie métallique 22.Fastening devices as defined above, are installed gradually between the rigid wings 38, 40, for example six in number, over the entire length of the amount of the metal joinery 22.

La présente invention concerne également un montant de menuiserie métallique équipé d'une têtière et d'un dispositif de fixation telle que défini ci-dessus selon le premier objet.The present invention also relates to an amount of metal joinery equipped with a headrest and a fixing device as defined above according to the first object.
