Abstract

It is made up of a relatively resilient and elastic material, and has a V-shaped profile of which the two arms (18, 19) are free and at rest form an angle slightly less than 90@, the apex (20) of the square (corner key) being tapered into a point, the said square being designed to house its arms in corresponding open grooves (12) provided in the two sections opposite rims (17) which are effectively parallel to the grooves, such that the square can be deformed by a force exerted on its apex substantially in the direction of the bisector of the angle formed by the two arms towards the centre of the frame, moving these arms into the grooves, separating them, until the moment when the apex can be slipped under the rims in the corner which they form at the junction of the two sections and against which it engages before the square is elastically relaxed by release of the force exerted. <IMAGE>

Description

La présente invention est relative à une pièce en équerre, permettant de réaliser la mise à niveau, c'est-à-dire l'affleurement dans un même plan contenant les faces correspondantes de deux profilés métalliques taillés en coupe d'onglet et assemblés pour former deux côtés d'un cadre ou châssis de fenêtre ou analogue.The present invention relates to a square piece, allowing the leveling, that is to say the outcropping in the same plane containing the corresponding faces of two metal profiles cut in miter section and assembled for forming two sides of a window frame or window frame or the like.

Dans les solutions classiques de réalisation de tels châssis en profilé métallique, utilisés en menuiserie d'aluminium notamment, ces profilés sont deux à deux coupés à leurs extrémités en onglet, avec une pente à 45°, de manière à permettre lors de leur aboutement, de former un des angles ou coins d'une structure de support recevant par exemple une paroi vitrée et des joints d'étanchéité.In the conventional solutions for producing such chassis in metal profile, used in aluminum carpentry in particular, these profiles are two by two cut at their ends in a miter, with a slope at 45 °, so as to allow when they abut, to form one of the angles or corners of a support structure receiving for example a glazed wall and seals.

Or, même avec des méthodes de fabrication très soigneuses et un processus de coupe des profilés effectué avec une grande précision, on constate que, lors de l'assemblage des deux profilés réunis l'un à l'autre selon leurs bords en biseau, se produit un certain désalignement, de telle sorte que l'un des profilés aeffleure en pratique légèrement en dessus ou en dessous de l'autre, en débordant du plan de celui-ci et en créant ainsi un décalage en épaisseur qui est la plupart du temps inacceptable.However, even with very careful manufacturing methods and a profile cutting process carried out with great precision, we note that, during the assembly of the two profiles joined to each other according to their bevelled edges, produces a certain misalignment, so that one of the profiles brushes in practice slightly above or below the other, projecting from the plane thereof and thus creating a thickness offset which is most of the time unacceptable.

Pour pallier cet inconvénient, la solution la plus usuelle consiste à prévoir dans les bords et selon les côtés des deux profilés, chacun s'assemblant avec l'autre dans la coupe à 45° de leurs extrémités, une rainure délimitée par des rebords parallèles et dans laquelle peut être introduite une petite équerre métallique en L, dont les branches sont parallèles à la direction longitudinale des deux profilés respectivement, cette équerre solidarisant ainsi les deux profilés et surtout maintenant les faces externes de ceux-ci rigoureusement dans le même plan.To overcome this drawback, the most usual solution consists in providing in the edges and along the sides of the two profiles, each joining with the other in the section at 45 ° from their ends, a groove delimited by parallel edges and into which can be introduced a small metal L-shaped square, the branches of which are parallel to the longitudinal direction of the two sections respectively, this square thus joining the two sections and above all maintaining the external faces thereof strictly in the same plane.

Mais cette solution présente divers inconvénients. En premier lieu, il est nécessaire que le monteur qui assemble les deux côtés d'un châssis quelconque n'oublie pas de mettre l'équerre en place, préalablement à cet assemblage. Par ailleurs, dans le cas de profilés peints ou laqués, l'insertion de l'équerre dans les rainures ad hoc des deux profilés est parfois difficile, voire impossible, du fait des surépaisseurs de peinture ou de laque qui risquent d'obstruer plus ou moins ces rainures.However, this solution has various drawbacks. First, it is necessary that the fitter who assembles the two sides of any chassis does not forget to put the square in place, prior to this assembly. In addition, in the case of painted or lacquered profiles, the insertion of the square in the ad hoc grooves of the two profiles is sometimes difficult, if not impossible, because of the extra thickness of paint or lacquer which may more or less obstruct these grooves.

De plus, pour que l'équerre donne un résultat satisfaisant et rigidifie de manière appropriée l'angle des deux profilés en maintenant ceux-ci dans le plan contenant les faces externes de ces profilés, il faut que l'équerre soit ajustée dans ses rainures avec de très faibles jeux. Or, les dimensions de ces rainures peuvent varier d'un profilé à l'autre, du fait des tolérances d'extrusion lors de la fabrication de ces profilés et de leur état de surface ou de finition qui n'est pas toujours très régulier.In addition, for the square to give a satisfactory result and to appropriately stiffen the angle of the two sections while keeping them in the plane containing the external faces of these sections, the square must be adjusted in its grooves. with very little play. However, the dimensions of these grooves can vary from one profile to another, due to the extrusion tolerances during the manufacture of these profiles and their surface finish or finish which is not always very regular.

Enfin, l'utilisation de la pièce en équerre anti-désaffleurement est rendue plus difficile du fait que, une fois que cette équerre est préalablement mise en place, les deux profilés doivent encore être réunis et assemblés de façon définitive au moyen d'une pièce de liaison qui s'insère également entre les deux profilés et qui peut être gênée lors de son engagement par les équerres déjà logées dans leurs rainures.Finally, the use of the anti-flush square piece is made more difficult because, once this square is previously put in place, the two sections must still be joined and assembled definitively by means of a piece connecting which also fits between the two profiles and which can be hindered during its engagement by the brackets already housed in their grooves.

La présente invention vise une pièce en équerre de conception différente qui évite ces inconvénients, notamment du fait qu'elle peut être mise en place sur les deux profilés après que ceux-ci aient été préalablement reliés ensemble, le cadre ou châssis étant complètement assemblé avant que la correction d'affleurement ne soit réalisée.The present invention relates to a square piece of different design which avoids these drawbacks, in particular because it can be put in place on the two profiles after they have been previously connected together, the frame or chassis being completely assembled before that the leveling correction is not carried out.

A cet effet, l'équerre d'affleurement considérée, destinée à être associée à deux profilés métalliques taillés à coupe d'onglet et formant ensemble une fois mutuellement assemblés l'angle ou le coin d'un châssis de fenêtre ou analogue, ladite équerre étant adaptée à loger ses branches dans des rainures homologues ouvertes prévues dans les deux profilés en regard de rebords respectivement parallèles aux rainures, se caractérise en ce qu'elle est constituée en un matériau relativement souple et élastique, et présente un profil en forme de V, dont les deux branches sont libres et forment au repos un angle légèrement inférieur à 90°, le sommet de l'équerre étant profilé en pointe, de telle sorte que l'équerre puisse être déformée par un effort exercé sur son sommet sensiblement dans la direction de la bissectrice de l'angle formé par les deux branches en direction du centre du châssis, déplaçant ces dernières dans les rainures en les écartant, jusqu'au moment où le sommet peut être glissé sous les rebords dans l'angle qu'ils forment à la jonction des deux profilés et contre lesquels il s'engage, avant détente élastique de l'équerre par relâchement de l'effort exercé.For this purpose, the outcrop angle considered, intended to be associated with two metal profiles cut to miter cut and forming together once mutually assembled the angle or the corner of a window frame or the like. being adapted to accommodate its branches in open homologous grooves provided in the two profiles opposite edges respectively parallel to the grooves, is characterized in that it is made of a relatively flexible and elastic material, and has a V-shaped profile , whose two branches are free and form at rest an angle slightly less than 90 °, the top of the bracket being shaped as a point, so that the bracket can be deformed by a force exerted on its vertex substantially in the direction of the bisector of the angle formed by the two branches in the direction of the center of the frame, moving the latter in the grooves by spreading them apart, until the summit can be slid under the edges in the angle that they form at the junction of the two sections and against which it engages, before elastic relaxation of the bracket by relaxation of the force exerted.

Dans un mode de réalisation préféré de réalisation, la pièce en équerre est réalisée en un matériau plastique présentant une certaine souplesse autorisant la déformation momentanée de son profil en V, notamment en polyéthylène, polyamide, polypropylène, ou encore en chlorure de polyvinyle semi-rigide.In a preferred embodiment, the square piece is made of a plastic material having a certain flexibility allowing the momentary deformation of its V-profile, in particular in polyethylene, polyamide, polypropylene, or in semi-rigid polyvinyl chloride .

Selon une autre caractéristique de l'invention, la face supérieure de la pièce en équerre au droit de son sommet à profil en V est légèrement amincie en biseau afin de permettre l'engagement du sommet sous les rebords jointifs des deux profilés.According to another characteristic of the invention, the upper face of the piece at right angles to its V-shaped top is slightly thinned at a bevel in order to allow engagement of the top under the contiguous edges of the two profiles.

Avantageusement et selon une autre caractéristique également, les branches latérales de la pièce en équerre comportent un décrochement dans leur épaisseur pour faciliter leur engagement dans les rainures des profilés où elles se déplacent consécutivement à l'effort exercé sur le sommet de la pièce.Advantageously and according to another characteristic also, the lateral branches of the square part have a recess in their thickness to facilitate their engagement in the grooves of the profiles where they move consecutively to the force exerted on the top of the part.

D'autres caractéristiques d'une pièce en équerre d'affleurement pour assurer la mise à niveau dans le même plan des faces externes de deux profilés constituant les côtés d'un châssis de fenêtre ou analogue, apparaîtront encore à travers la description qui suit d'un exemple de réalisation donné à titre indicatif et non limitatif, en référence aux dessins annexés sur lesquels :

  • La Figure 1 est une vue en perspective et en coupe partielle de deux profilés métalliques, taillés à coupe d'onglet et assemblés l'un à l'autre pour former, de façon banale dans la technique, un coin d'un châssis de fenêtre ou analogue, ces deux profilés faisant apparaître après assemblage un décalage ou désaffleurement de leurs faces externes.
  • La Figure 2 est une vue en perspective éclatée à plus faible échelle, montrant les profilés de la Figure 1, préalablement à leur assemblage et à la mise en place d'une équerre métallique permettant, de façon connue dans la technique, d'éviter en partie l'effet de désaffleurement des faces de ces profilés.
  • La Figure 3 est une vue en perspective à plus grande échelle de la pièce en équerre selon l'invention, représentée lors de sa mise en place dans le coin formé par les deux profilés.
  • La Figure 4 est une vue en coupe transversale à encore plus grande échelle du châssis formé par l'assemblage des deux profilés, selon un plan passant par la ligne de jonction de ces derniers et coupant la pièce en équerre selon sa bissectrice.
Other characteristics of a part at a right angle to ensure the leveling in the same plane of the external faces of two profiles constituting the sides of a window frame or the like, will become more apparent from the following description of '' an exemplary embodiment given by way of non-limiting example, with reference to the appended drawings in which:
  • Figure 1 is a perspective view in partial section of two metal profiles, cut to miter cut and joined to each other to form, in the ordinary way in the art, a corner of a window frame or the like, these two sections showing, after assembly, an offset or a mismatching of their external faces.
  • Figure 2 is an exploded perspective view further small scale, showing the profiles of Figure 1, prior to their assembly and the establishment of a metal bracket making it possible, in a manner known in the art, to partially avoid the effect of flushing of the faces of these profiles .
  • Figure 3 is a perspective view on a larger scale of the square piece according to the invention, shown when it is placed in the corner formed by the two sections.
  • Figure 4 is a cross-sectional view on an even larger scale of the chassis formed by the assembly of the two sections, according to a plane passing through the junction line of the latter and cutting the piece at right angles to its bisector.

Sur la Figure 1, la référence 1 désigne un châssis pour fenêtre ou analogue, formé de façon en elle-même bien connue dans la technique, notamment dans celle de la menuiserie métallique, au moyen de deux profilés, respectivement 2 et 3, de même section, ces profilés étant taillés ou coupés à leurs extrémités s'assemblant l'une à l'autre selon un plan matérialisant une ligne de jonction 4 s'étendant à 45° par rapport à la direction longitudinale de chacun des profilés.In Figure 1, the reference 1 designates a window frame or the like, formed in itself well known in the art, especially in that of metal carpentry, by means of two profiles, respectively 2 and 3, similarly section, these profiles being cut or cut at their ends joining together according to a plane embodying a junction line 4 extending at 45 ° relative to the longitudinal direction of each of the profiles.

D'une façon classique, en dépit du soin apporté à la fabrication des profilés 2 et 3, généralement réalisés par extrusion et à la coupe de leurs extrémités pour leur assemblage selon la ligne 4 en formant ensemble un des coins du châssis 1, on constate que ces profilés ne sont pas parfaitement jointifs et en particulier qu'ils font apparaître entre leurs faces successives au droit de la ligne 4 un léger décalage 5, la face externe notamment de l'un des profilés se situant en dessus ou en dessous du plan de la face de l'autre profilé, ce qui nuit à l'esthétique de l'ensemble et également peut être dangereux pour les monteurs et les utilisateurs du châssis en raison des angles vifs découverts au droit de ce décalage.In a conventional manner, despite the care taken in the manufacture of the sections 2 and 3, generally produced by extrusion and in cutting their ends for their assembly along the line 4, together forming one of the corners of the frame 1, it is found that these profiles are not perfectly contiguous and in particular that they show between their successive faces at the right of the line 4 a slight offset 5, the external face in particular of one of the profiles being located above or below the plane from the face of the other profile, which detracts from the aesthetics of the assembly and also can be dangerous for the fitters and users of the chassis because of the sharp angles discovered at the right of this offset.

La Figure 2 montre en perspective éclatée les deux profilés 2 et 3 avec leurs bords d'extrémité taillés à 45° pour définir leur ligne de jonction 4, l'assemblage des deux profilés étant réalisé au moyen d'une patte de liaison coudée 6 qui s'engage dans des logements tels que 7 prévus à l'intérieur des profilés, avant d'être solidarisée de ces derniers. Une telle solution est également usuelle et, pour éviter ou au moins limiter le décalage entre les deux profilés tels que rappelés plus haut, prévoit l'utilisation d'une pièce métallique en équerre 8, coudée à angle droit et dont les branches telles que 9 sont prévues pour venir s'engager dans une rainure complémentaire 10 ménagée dans la face interne des profilés au voisinage des côtés de ceux-ci qu'il convient de ramener dans le même plan pour éliminer dans la meilleure mesure possible le désaffleurement autrement constaté.Figure 2 shows in exploded perspective the two profiles 2 and 3 with their end edges cut at 45 ° to define their junction line 4, the assembly of the two profiles being carried out by means of a bent connecting tab 6 which engages in housings such as 7 provided inside the profiles, before being joined to the latter. Such a solution is also usual and, to avoid or at least limit the offset between the two profiles as mentioned above, provides for the use of a metal piece at an angle 8, bent at a right angle and whose branches such as 9 are provided to engage in a complementary groove 10 formed in the internal face of the profiles in the vicinity of the sides thereof which should be brought in the same plane to eliminate as best as possible the mismatch otherwise noted.

Mais, cette solution n'est pas facile à mettre en oeuvre, l'engagement des équerres 8 dans chaque coin du châssis devant être effectué préalablement à la mise en place des pattes de liaison qui réalisent l'assemblage proprement dit des profilés, ce qui induit des efforts sur ces équerres et risque de les fausser sans pouvoir réduire finalement de façon significative le décalage entre les faces externes des profilés. Inversement, si ces pattes sont d'abord mises en place et solidarisent les deux profilés l'un avec l'autre dans le coin correspondant, l'engagement des équerres dans leurs rainures est pratiquement impossible.However, this solution is not easy to implement, the engagement of the brackets 8 in each corner of the chassis having to be carried out prior to the installation of the connecting lugs which carry out the actual assembly of the profiles, which induces efforts on these brackets and risks distorting them without being able to ultimately significantly reduce the offset between the external faces of the profiles. Conversely, if these tabs are first put in place and secure the two sections with one another in the corresponding corner, the engagement of the brackets in their grooves is practically impossible.

Les Figures 3 et 4 illustrent une pièce d'équerre 11 réalisée conformément à l'invention et qui peut notamment être mise en place dans les deux profilés 2 et 3 après que ces derniers aient été assemblés entre eux, cette mise en place pouvant être réalisée sans être gênée par les pattes de liaison préalablement fixées. Sur ces Figures, ces pattes de liaison n'ont pas été figurées afin de simplifier les dessins.Figures 3 and 4 illustrate a square piece 11 produced in accordance with the invention and which can in particular be put in place in the two profiles 2 and 3 after the latter have been assembled together, this positioning being able to be carried out without being hindered by the previously attached connecting tabs. In these Figures, these connecting tabs have not been shown in order to simplify the drawings.

Chacun des deux profilés 2 ou 3 comporte une rainure 12, de préférence délimitée entre le fond plat 13 du profilé et une partie en saillie 14 ménagée dans un flan 15 perpendiculaire au fond 13. En outre, en regard de la rainure 12, chaque profilé comporte un retour vertical 16, parallèle au flan 15 et terminé par un rebord 17, lui-même parallèle au fond 13 et s'étendant à une certaine distance de celui-ci.Each of the two profiles 2 or 3 has a groove 12, preferably delimited between the flat bottom 13 of the profile and a protruding part 14 formed in a blank 15 perpendicular to the bottom 13. In addition, opposite the groove 12, each profile comprises a vertical return 16, parallel to the blank 15 and terminated by a flange 17, itself parallel to the bottom 13 and extending at a certain distance from the latter.

Selon l'invention, la pièce en équerre 11 est réalisée en une matière plastique appropriée présentant une relative rigidité mais en même temps la faculté de se déformer élastiquement sous un effort approprié, avant que, lorsque cet effort esr relâché, l'équerre ne reprenne sa forme initiale.According to the invention, the square piece 11 is made of a suitable plastic material having a relative rigidity but at the same time the faculty of being elastically deformed under an appropriate effort, before, when this effort is released, the square returns to its initial shape.

La pièce 11 présente un profil en forme de V, d'angle au sommet légèrement inférieur à 90°, les branches latérales 18 et 19 du V étant réunies par un élément de liaison 20, au sommet de l'équerre.The part 11 has a V-shaped profile, with an angle at the top slightly less than 90 °, the lateral branches 18 and 19 of the V being joined by a connecting element 20, at the top of the bracket.

A leurs extrémités opposées au sommet 20, les deux branches 18 et 19 de l'équerre 11 comportent un décrochement 21, épousant dans le cas de l'exemple représenté, la forme d'un pion dont la dimension en largeur correspond sensiblement à la hauteur de la rainure 12 de manière à permettre à ce pion de s'engager librement dans cette rainure, et ceci pour chacune des branches de la pièce en équerre selon les flans 15 des deux profilés 2 et 3 respectivement.At their ends opposite the vertex 20, the two branches 18 and 19 of the bracket 11 have a recess 21, taking in the case of the example shown, the shape of a pin whose width dimension corresponds substantially to the height of the groove 12 so as to allow this pin to freely engage in this groove, and this for each of the branches of the square piece according to the blanks 15 of the two sections 2 and 3 respectively.

Dans son sommet 20, la pièce en équerre présente une diminution d'épaisseur correspondant notamment à une partie 21 de la pièce taillée en biseau, le sommet comportant en outre à l'opposé de cette partie 20 une contre-dépouille 22 également à face légèrement inclinée sur la direction longitudinale des branches 18 et 19.In its top 20, the square part has a reduction in thickness corresponding in particular to a part 21 of the part cut in a bevel, the top further comprising opposite this part 20 an undercut 22 also with slightly face inclined to the longitudinal direction of the branches 18 and 19.

La mise en oeuvre de la pièce en équerre 11 se déduit aisément des explications qui précèdent : les profilés 2 et 3 étant assemblés entre eux et présentant au montage un certain décalage entre eux, chacun des coins formés par deux profilés consécutifs dans le châssis est associé à une pièce 11 du genre décrit, cette dernière étant présentée sensiblement selon la direction de la ligne de jonction 4 entre les profilés, de telle sorte que les décrochements ou pions 21, prévus en bout des branches 18 et 19, s'engagent dans les rainures 12 prévues sur chacun de ces profilés, la pièce étant présentée légèrement en biais comme représenté sur la Figure 3.The implementation of the square part 11 is easily deduced from the foregoing explanations: the sections 2 and 3 being assembled together and having a certain offset between them during assembly, each of the corners formed by two consecutive sections in the chassis is associated to a part 11 of the kind described, the latter being presented substantially in the direction of the junction line 4 between the profiles, so that the recesses or pins 21, provided at the end of the branches 18 and 19, engage in the grooves 12 provided on each of these profiles, the part being presented slightly at an angle as shown in FIG. 3.

Dans l'étape suivante, on exerce sur le sommet 20 un effort dirigé sensiblement selon la direction de la bissectrice du V formé par les branches 18 et 19 de la pièce 11, comme schématisé par la flèche 23, cet effort provoquant une déformation du V avec écartement des branches 18 et 19 qui se déplacent légèrement dans les rainures 12. Lorsque l'extrémité en biseau 21 du sommet 20 se trouve à l'aplomb du rebord 17 et à l'intérieur de celui-ci, il suffit alors d'appliquer l'équerre en direction du fond 13 des profilés pour amener l'extrémité 21 sous ce rebord avant que, l'effort d'enfoncement étant relâché, les branches 18 et 19 ne reviennent en position initiale, en immobilisant l'extrémité 21 par le dessus du rebord 17 comme illustré sur la Figure 4.In the next step, a force is exerted on the top 20 directed substantially in the direction of the bisector of the V formed by the branches 18 and 19 of the part 11, as shown diagrammatically by the arrow 23, this force causing a deformation of the V with spacing of the branches 18 and 19 which move slightly in the grooves 12. When the beveled end 21 of the apex 20 is plumb with the rim 17 and inside of it, it then suffices to apply the square in the direction of the bottom 13 of the profiles to bring the end 21 under this rim before, the driving force being released, the branches 18 and 19 return to the initial position, immobilizing the end 21 by the above the rim 17 as illustrated in Figure 4.

Grâce à sa rigidité propre, l'équerre 11 ainsi mise en place exerce sur les deux profilés un effort limité mais néanmoins suffisant pour s'opposer à la flexion créée par le décalage de ces profilés en ramenant ceux-ci dans le même plan où l'équerre ne subit plus elle-même d'effort de torsion.Thanks to its own rigidity, the square 11 thus put in place exerts on the two profiles a limited force but nevertheless sufficient to oppose the bending created by the offset of these profiles by bringing them back in the same plane where the The bracket itself no longer undergoes torsional stress.

On réalise ainsi une pièce en équerre de conception très simple, peu coûteuse, facile et rapide à mettre en place et qui tolère aisément les éventuelles variations dimensionnelles des rainures qui reçoivent ses branches, l'immobilisation de l'équerre sous le rebord des profilés prévu à cet effet s'effectuant à la manière d'un clip pratiquement indélogeable une fois fixé en position.This produces a square piece of very simple design, inexpensive, easy and quick to set up and which easily tolerates any dimensional variations of the grooves which receive its branches, the immobilization of the square under the edge of the profiles provided for this purpose taking place in the manner of a practically entrenched clip once fixed in position.

Bien entendu, il va de soi que l'invention ne se limite pas à l'exemple de réalisation plus spécialement décrit et représenté ci-dessus ; elle en embrasse au contraire toutes les variantes.Of course, it goes without saying that the invention is not limited to the embodiment more specifically described and shown above; on the contrary, it embraces all its variants.
