Description

La présente invention est relative à une structure spatiale en treillis constituée d'au moins une nappe plane ou un voile à simple ou double courbure.The present invention relates to a spatial lattice structure consisting of at least one flat sheet or a single or double curvature veil.

Dans une telle structure, la nappe ou le voile est formé par des éléments constitués chacun par une barre, un cadre ou une pyramide. Ces éléments préfabriqués sont assemblés entre eux aux extrémités de leurs membrures constitutives en des noeuds par boulonnage mutuel de ces extrémités.In such a structure, the sheet or veil is formed by elements each consisting of a bar, a frame or a pyramid. These prefabricated elements are assembled together at the ends of their constituent members in nodes by mutual bolting of these ends.

Il existe déjà plusieurs systèmes de réalisation des noeuds des membrures faisant partie d'une nappe plane ou d'un voile courbé. Parmi ces différents systèmes de réalisation connus, il en est un qui met en oeuvre des pièces d'about rapportées respectivement aux extrémités des membrures. A chaque noeud, les pièces d'about des membrures correspondantes prennent appui deux à deux l'une contre l'autre et sont solidarisées entre elles des deux côtés de la nappe ou du voile, par deux plaques de recouvrement qui y sont boulonnées. En fait, chaque pièce d'about comprend un bout de tube et plusieurs plaques. Le bout de tube est destiné à être emboité sans jeu appréciable et boulonné par rapport à l'extrémité de la membrure. Une plaque carrée est soudée à l'extrémité du bout de tube perpendiculairement à son axe. Du côté opposé au bout de tube, deux plaques polygonales identiques sont soudées le long des bords supérieur et inférieur de la plaque carrée parallèlement entre elles et à l'axe susdit. En outre, une plaque intermédiaire rectangulaire est soudée à la plaque carrée et aux plaques polygonales et assure l'entretoisement de ces dernières. Chaque plaque polygonale présente une pointe à bords isocèles du côté opposé au bout du tube.There are already several systems for making the nodes of the members forming part of a flat sheet or of a curved veil. Among these various known embodiments, there is one which implements end pieces attached respectively to the ends of the members. At each node, the end pieces of the corresponding members bear two by two against each other and are joined together on both sides of the sheet or web, by two cover plates which are bolted to it. In fact, each end piece includes a tube end and several plates. The end of the tube is intended to be fitted without appreciable play and bolted in relation to the end of the frame. A square plate is welded at the end of the end of the tube perpendicular to its axis. On the side opposite the end of the tube, two identical polygonal plates are welded along the upper and lower edges of the square plate parallel to each other and to the above axis. In addition, a rectangular intermediate plate is welded to the square plate and the polygonal plates and ensures the bracing of the latter. Each polygonal plate has a point with isosceles edges on the side opposite the end of the tube.

Lors de l'assemblage d'un noeud dans cette structure, les bords isocèles supérieur et inférieur des plaques polygonales de chaque pièce d'about prennent appui respectivement contre les bords adjacents des plaques similaires des deux pièces d'about voisines. Ensuite, les plaques de recouvrement sont posées contre les plaques polygonales supérieures et inférieures et y sont boulonnées par des boulons engagés à travers des trous correspondants de toutes ces plaques.When assembling a knot in this structure, the upper and lower isosceles edges of the polygonal plates of each end piece bear respectively against the adjacent edges of the similar plates of the two adjacent end pieces. Then, the cover plates are placed against the upper and lower polygonal plates and are bolted to them by bolts engaged through corresponding holes in all these plates.

Ainsi, dans ce système connu, les pièces d'about sont rapportées par des boulons sur les extrémités des membrures et sont assemblées entre elles par l'intermédiaire des plaques de recouvrement parallèles. Il y a donc à chaque noeud de ce système, une double liaison mécanique par boulons tous dirigés parallèlement entre eux et perpendiculairement aux axes des membrures. De plus, il n'y a aucune solidarisation mutuelle directe des pièces d'about entre elles. De ce fait, ce système ne peut réaliser que des noeuds nécessitant des pièces détachées,à savoir les plaques de recouvrement,et présentant des caractéristiques d'encastrement limitées.Thus, in this known system, the end pieces are attached by bolts to the ends of the members and are assembled together by means of the parallel cover plates. There is therefore at each node of this system, a mechanical double connection by bolts all directed parallel to each other and perpendicular to the axes of the members. In addition, there is no direct mutual joining of the end pieces together. Therefore, this system can only make nodes requiring spare parts, namely the cover plates, and having limited embedding characteristics.

L'objet de l'invention est une nouvelle structure spatiale dans laquelle les noeuds sont conçus et réalisés pour remédier aux inconvénients précités de la technique connue.The object of the invention is a new spatial structure in which the nodes are designed and produced to remedy the aforementioned drawbacks of the known technique.

A cet effet, dans la structure spatiale selon l'invention, chaque extrémité des membrures aboutissant à un noeud porte un tenon formé par une paroi qui y est soudée et par une cornière dont les ailes de même largeur sont soudées à la paroi et présentent chacune au moins un trou d'assemblage. De la sorte, chaque noeud est formé d'une part, par la superposition deux à deux des ailes des cornières des membrures correspondantes, avec les arêtes de ces cornières alignées pratiquement suivant une même droite normale à la nappe ou au voile , et d'autre part, par le boulonnage de ces ailes superposées au moyen de boulons traversant leurs trous d'assemblage coaxiaux.To this end, in the spatial structure according to the invention, each end of the frames leading to a knot carries a stud formed by a wall which is welded therein and by an angle iron whose wings of the same width are welded to the wall and each have at least one assembly hole. In this way, each knot is formed on the one hand, by the superimposition two by two of the angles of the angles of the corresponding members, with the edges of these angles aligned practically along the same straight line normal to the web or to the veil, and on the other hand, by the bolting of these superimposed wings by means of bolts passing through their coaxial assembly holes.

Dans la nouvelle structure spatiale, la fixation ferme des cornières par rapport aux membrures d'une part, et la superposition et le boulonnage directs de ces cornières d'autre part, assurent un degré très élevé d'encastrement de ces membrures aux noeuds. Un tel encastrement réduit non seulement la longueur de flambage des membrures en augmentant leur raideur et la stabilité au voilement de la nappe ou du voile, mais aussi les moments de flexion de ces membrures en augmentant la résistance à la flexion de cette nappe ou de ce voile. D'autre part, l'assemblage direct de ces cornières élimine toute pièce intermédiaire indépendante des membrures. En somme, la nappe ou le voile est réalisé uniquement à l'aide de membrures complètement préfabriquées et avantageusement normalisées, et au moyen de boulons. Une telle réalisation est particulièrement économique.In the new spatial structure, the firm fixing of the angles relative to the members on the one hand, and the direct superposition and bolting of these angles on the other hand, ensure a very high degree of embedding of these members to the nodes. Such embedding not only reduces the buckling length of the members by increasing their stiffness and the buckling stability of the web or web, but also the bending moments of these members by increasing the bending resistance of this web or of this sail. On the other hand, the direct assembly of these angles eliminates any independent intermediate piece of the members. In short, the web or the veil is produced only using completely prefabricated and advantageously standardized members, and by means of bolts. Such an achievement is particularly economical.

Généralement, dans la structure spatiale selon l'invention, le tenon précité comprend me paroi qui est par exemple formée par un plat carré ou rectangulaire, et une cornière dont l'arête est parallèle au plat.Generally, in the spatial structure according to the invention, the aforementioned tenon comprises the wall which is for example formed by a square or rectangular dish, and an angle iron whose edge is parallel to the dish.

Selon une particularité importante de cette nouvelle structure spatiale, un plan particulier passant par l'axe longitudinal d'une membrure dont les deux extrémités sont pourvues respectivement de deux tenons, coupe suivant des angles égaux, les arêtes des cornières de ces deux tenons et ainsi, après assemblage, les arêtes des cornières des tenons relatifs aux deux noeuds correspondants.According to an important feature of this new spatial structure, a particular plane passing through the longitudinal axis of a frame, the two ends of which are respectively provided with two studs, cut at equal angles, the edges angles of these two studs and thus, after assembly, the edges of the angles of the studs relating to the two corresponding nodes.

Dans le cas d'une structure spatiale comportant une nappe plane, les arêtes des cornières des deux tenons de la membrure sont parallèles entre elles dans le plan particulier susdit passant par l'axe longitudinal de cette membrure, en sorte que les angles de coupe de ces arêtes par ce plan soient nuls. Dans le cas d'une structure spatiale comportant un voile sous forme de sphère, les arêtes des cornières des deux tenons de la membrure sont convergentes au centre de la surface sphérique dans le plan particulier susdit. Dans le cas d'une structure spatiale comportant un voile sous forme de cylindre ou de parabololde hyperbolique, les arêtes des cornières des deux tenons de la membrure sont gauches entre elles et se trouvent hors du plan particulier susdit.In the case of a spatial structure comprising a flat sheet, the edges of the angles of the two studs of the frame are mutually parallel in the aforementioned particular plane passing through the longitudinal axis of this frame, so that the cutting angles of these edges by this plane are zero. In the case of a spatial structure comprising a veil in the form of a sphere, the edges of the angles of the two tenons of the member are convergent at the center of the spherical surface in the aforementioned particular plane. In the case of a spatial structure comprising a veil in the form of a cylinder or of a hyperbolic parabolold, the edges of the angles of the two tenons of the member are left between them and lie outside the above-mentioned particular plane.

Pour augmenter la résistance des noeuds de la structure spatiale selon l'invention, la cornière du tenon est renforcée. à mi-hauteur par un raidisseur triangulaire soudé à des ailes et à la paroi de ce tenon.To increase the resistance of the nodes of the spatial structure according to the invention, the angle of the post is reinforced. at mid-height by a triangular stiffener welded to the wings and to the wall of this post.

Dans le cas où la structure spatiale comprend deux nappes planes superposées entretoisées par des diagonales tubulaires, les extrémités de chaque diagonale sont aplaties et présentent chacune au moins un trou d'assemblage. En outre, chaque extrémité est insérée entre deux ailes superposées de deux cornières du noeud correspondant et est boulonnée à ces ailes par le ou les boulons d'assemblage de ces dernières.In the case where the spatial structure comprises two superimposed flat sheets braced by tubular diagonals, the ends of each diagonal are flattened and each have at least one assembly hole. In addition, each end is inserted between two superposed wings of two angles of the corresponding node and is bolted to these wings by the assembly bolt (s) of the latter.

La structure spatiale selon l'invention peut comprendre généralement une ou plusieurs nappes planes 1 superposées, un ou plusieurs voiles 2 superposés sous forme de cylindre ou de parabololde hyperbolique ou un ou plusieurs voiles 3 superposés sous forme de sphère. En substance, la structure spatiale est une construction en treillis formée par des éléments successifs assemblés entre eux en des noeuds 4. Dans les exemples représentés, les éléments constitutifs de la structure spatiale sont chaque fois des membrures formée chacune par une barre constituée par exemple d'un tube rond, cette barre pouvant être un autre profilé. Cependant, dans des variantes, les éléments constitutifs en question peuvent être des cadres ou des pyramides formés de plusieurs membrures.The spatial structure according to the invention may generally comprise one or more flat layers 1 superimposed, one or more veils 2 superimposed in the form of a cylinder or hyperbolic paraboloid or one or more veils 3 superimposed in the form of a sphere. In essence, the spatial structure is a lattice construction formed by successive elements assembled together in nodes 4. In the examples shown, the constituent elements of the spatial structure are each time members formed each by a bar constituted for example by 'a round tube, this bar can be another profile. However, in variants, the constituent elements in question may be frames or pyramids formed by several members.

Dans le cas d'une seule nappe plane 1 (figures 1 et 2) chaque noeud 4 assure par exemple l'assemblage des extrémités de quatre membrures 5 convergentes. Dans la nappe 1, les membrures 5 sont parallèles deux à deux et forment des rectangles ou des carrés réguliers. Chaque extrémité d'une membrure 5 quelconque porte un tenon comprenant une paroi plane 6 et une cornière 7. La paroi 6 pourrait être bombée. Dans le cas considéré, la paroi plane 6 présente sensiblement une configuration carrée ou rectangulaire. Le plat 6 est soudé à l'extrémité de la membrure 5 et est disposé pour présenter deux bords verticaux et deux bords horizontaux.In the case of a single flat sheet 1 (Figures 1 and 2) each node 4 ensures for example the assembly of the ends of four convergent members 5. In the ply 1, the members 5 are parallel in pairs and form regular rectangles or squares. Each end of any member 5 carries a tenon comprising a flat wall 6 and an angle 7. The wall 6 could be curved. In the case under consideration, the flat wall 6 has substantially a square or rectangular configuration. The plate 6 is welded to the end of the frame 5 and is arranged to have two vertical edges and two horizontal edges.

D'autre part, la cornière 7 comporte deux ailes identiques ou de même largeur faisant entre elles par exemple un angle droit. Entre ses ailes, la cornière 7 est légèrement chanfreinée. En fait, la cornière 7 est soudée par les bords de ses ailes, le long des bords verticaux du plat 6. Ainsi, la cornière 7 présente son arête fictive dirigée verticalement. Dans chaque membrure 5 pourvue de ses tenons d'extrémité, le plan vertical passant par l'axe longitudinal de la membrure 5 contient les arêtes fictives des cornières 7 et coupe donc celles-ci suivant des angles nuls, ces arêtes étant d'ailleurs parallèles entre elles dans ce plan vertical. Dans chaque noeud 4, les plans verticaux relatifs aux membrures 5 passent tous par la droite commune d'alignement des arêtes fictives des cornières 7 et font des angles nuls avec cette droite commune, laquelle est perpendiculaire à la surface plane de la nappe 1. Par ailleurs, les ailes des quatre cornières 7 sont superposées et boulonnées deux à deux, par des boulons 8 traversant des trous d'assemblage prévus dans ces ailes et alignés coaxialement.On the other hand, the angle iron 7 has two identical wings or the same width forming between them for example a right angle. Between its wings, the angle 7 is slightly chamfered. In fact, the angle iron 7 is welded by the edges of its wings, along the vertical edges of the plate 6. Thus, the angle iron 7 has its fictitious edge directed vertically. In each member 5 provided with its end tenons, the vertical plane passing through the longitudinal axis of the member 5 contains the fictitious edges of the angles 7 and therefore cuts these at zero angles, these edges being moreover parallel between them in this vertical plane. In each node 4, the vertical planes relative to the members 5 all pass through the common straight line of alignment of the fictitious edges of the angles 7 and make zero angles with this common straight line, which is perpendicular to the flat surface of the sheet 1. By moreover, the wings of the four angles 7 are superimposed and bolted two by two, by bolts 8 passing through assembly holes provided in these wings and aligned coaxially.

Dans le cas d'un seul voile 2 sous forme de cylindre ou de parabololde hyperbolique (figures 3 et 4), chaque noeud 4 assure par exemple l'assemblage des extrémités de quatre membrures 5 et de deux diagonales 9, toutes convergentes. Dans le voile 2, les diagonales 9 sont alignées respectivement suivant des droites équidistantes parallèles à la génératice de la surface cylindrique, tandis que les membrures 5 sont parallèles deux à deux chaque fois uniquement entre deux séries rectilignes de diagonales 9. Le voile 2 est ainsi constitué de triangles isocèles bien montrés à la figure 4 et ayant chacun comme base, une diagonale 9 et comme côtés égaux, deux membrures 5 voisines.In the case of a single web 2 in the form of a cylinder or a hyperbolic paraboloid (FIGS. 3 and 4), each node 4 ensures, for example, the assembly of the ends of four members 5 and two diagonals 9, all converging. In the veil 2, the diagonals 9 are aligned respectively along equidistant lines parallel to the generatice of the cylindrical surface, while the members 5 are parallel two by two each time only between two straight series of diagonals 9. The veil 2 is thus consisting of isosceles triangles well shown in Figure 4 and each having as a base, a diagonal 9 and as equal sides, two neighboring members 5.

A chaque extrémité d'une membrure 5 quelconque est encore soudé un tenon comportant un plat 6 auquel sont soudées les ailes d'une cornière 7 dont l'arête non chanfreinée est parallèle au plat 6. Il s'agit d'un tenon soudé semblable à celui de la première figure. Dans chaque membrure 5 pourvue de ses deux tenons d'extrémité, il existe un plan passant par l'axe longitudinal de la membrure 5 et coupant les arêtes des cornières 7 suivant des angles égaux différents de zéro. Dans le cas du voile 2, les deux arêtes en question sont deux segments de droite gauches disposés de part et d'autre du plan particulier précité.At each end of any member 5 is still welded a stud comprising a flat 6 to which are welded the wings of an angle iron 7 whose non-chamfered edge is parallel to the flat 6. It is a welded stud similar to that of the first figure. In each member 5 provided with its two end tenons, there is a plane passing through the longitudinal axis of the member 5 and cutting the edges of the angles 7 at equal angles other than zero. In the case of web 2, the two edges in question are two left straight segments arranged on either side of the aforementioned particular plane.

Dans chaque noeud 4, les plans particuliers relatifs aux membrures 5 coupent la droite commune d'alignement des arêtes des cornières 7 suivant des angles égaux non nuls, cette droite commune étant normale à la surface du voile 2.In each node 4, the particular planes relating to the members 5 intersect the common line of alignment of the edges of the angles 7 according to equal non-zero angles, this common line being normal to the surface of the web 2.

Par ailleurs, chaque extrémité 10 d'une diagonale 9 quelconque est simplement aplatie comme le montre la figure 3. Au montage des quatre membrures 5 et des deux diagonales 9, les extrémités aplaties 10 des deux diagonales 9 sont boulonnées par des boulons 11 sur un plat commun 12. Ce plat 12 s'étend à travers le noeud 4 entre les cornières 7 et est inséré entre ces dernières. En fait, le plat 12 et les ailes des cornières 7 des membrures 5 entre lesquelles se trouvent les diagonales 9 sont boulonnées ensemble par des boulons 8 introduits dans des trous corres- pondants coaxiaux de ces ailes et de ce plat 12.Furthermore, each end 10 of any diagonal 9 is simply flattened as shown in Figure 3. When mounting the four frames 5 and two diagonals 9, the flattened ends 10 of the two diagonals 9 are bolted by bolts 11 on a common dish 12. This dish 12 extends through the node 4 between the angles 7 and is inserted between the latter. In fact, the dish 12 and the wings of the brackets 7 of the flanges 5 between which the diagonals lie 9 are bolted together by bolts 8 inserted in holes corre - sponding coaxial of these wings 12 and of the dish.

Dans le cas d'un seul voile sphérique 3 (figures 5 et 6), chaque noeud 4 assure l'assemblage des extrémités de quatre membrures 5 convergentes par exemple. Dans le voile 3, deux membrures 5 voisines quelconques sont alignées différemment. Le voile 3 est constitué de parallélogrammes déformés s'étendant dans deux plans non parallèles. Chaque extrémité d'une membrure 5 quelconque est encore réalisée comme dans les deux cas précédents avec un tenon formé par un plat 6 et une cornière 7. Dans chaque membrure 5 pourvue de ses deux tenons d'extrémité, il existe un plan particulier passant par l'axe longitudinal de la membrure et par les arêtes des cornières 7 de ces tenons. Ce plan coupe donc suivant des angles nuls ces arêtes dont les prolongements se coupent au centre de la surface sphérique du voile 3. Dans chaque noeud 4, les plans particuliers relatifs aux membrures 5 passent tous par la droite commune d'alignement des arêtes des cornières 7, cette droite commune étant normale à la surface sphérique du voile 3.In the case of a single spherical veil 3 (FIGS. 5 and 6), each node 4 ensures the assembly of the ends of four convergent members 5 for example. In the web 3, any two neighboring members 5 are aligned differently. Veil 3 is made up deformed parallelograms extending in two non-parallel planes. Each end of any member 5 is also made as in the two previous cases with a tenon formed by a flat 6 and an angle 7. In each member 5 provided with its two end tenons, there is a particular plane passing through the longitudinal axis of the member and by the edges of the angles 7 of these studs. This plane therefore cuts at zero angles these edges whose extensions intersect at the center of the spherical surface of the web 3. In each node 4, the particular planes relating to the members 5 all pass through the common straight line of alignment of the angles of the angles 7, this common straight line being normal to the spherical surface of the web 3.

Lorsque la structure spatiale comprend deux nappes planes 1 superposées comme montré à la figure 8, les nappes 1 constituées et réalisées comme dans le premier cas sont reliées entre elles par des diagonales 13 dont les extrémités sont aplaties et perforées. Au montage, l'extrémité inférieure aplatie d'une diagonale 13 est insérée entre deux ailes adjacentes de deux cornières 7 d'un noeud 4 de la nappe inférieure 1 et est boulonnée avec ces ailes. En outre, l'extrémité supérieure aussi aplatie de la diagonale 13 est insérée entre les deux ailes contiguës de deux cornières 7 d'un noeud 4 de la nappe supérieure et est boulonnée avec ces ailes. Les nappes 1 étant parallèles, les diagonales 13 d'un noeud 4 sont toutes semblablement inclinées par rapport à la droite d'alignement des arêtes des cornières 7 relatives à ce noeud 4. La figure 7 illustre clairement l'assemblage des . extrémités des membrures 5 et des diagonales 13 à un noeud 4 quelconque de la nappe inférieure. Il en est de même pour la nappe supérieure.When the spatial structure comprises two flat layers 1 superimposed as shown in FIG. 8, the layers 1 formed and produced as in the first case are connected to each other by diagonals 13 the ends of which are flattened and perforated. During assembly, the flattened lower end of a diagonal 13 is inserted between two adjacent wings of two angles 7 of a node 4 of the lower ply 1 and is bolted with these wings. In addition, the also flattened upper end of the diagonal 13 is inserted between the two contiguous wings of two angles 7 of a node 4 of the upper ply and is bolted with these wings. The sheets 1 being parallel, the diagonals 13 of a node 4 are all similarly inclined with respect to the straight line of alignment of the edges of the angles 7 relative to this node 4. FIG. 7 clearly illustrates the assembly of. ends of the members 5 and of the diagonals 13 at any node 4 of the lower ply. It is the same for the upper layer.

La liaison de deux nappes planes 1 par des diagonales 13 peut se faire comme dans le cas de deux voiles 2 et 3 superposés.The connection of two flat layers 1 by diagonals 13 can be done as in the case of two superimposed webs 2 and 3.

Ainsi que le montre la figure 9, un même plat 6 peut être commun, en y étant soudé, à deux extrémités de deux membrures 5 ou éventuellement d'une membrure et d'une diagonale, au lieu de l'être à l'extrémité d'une seule membrure 5. En outre, l'angle des ailes de chaque cornière 7 vaut 120° au lieu de 90°. En théorie, chaque noeud 4 comporte des cornières 7 dont le nombre est égal à celui des plats 6 et dont les ailes délimitent entre elles des angles égaux à 360° divisés par ce nombre.Quoi qu'il en soit, l'assemblage par superposition des ailes des cornières 7 et par boulonnage de ces ailes est pareil aux cas précédents.As shown in Figure 9, the same plate 6 may be common, by being welded to it, at two ends of two members 5 or possibly of a member and a diagonal, instead of being at the end of a single member 5. In addition, the angle of the wings of each angle 7 is 120 ° instead of 90 °. In theory, each node 4 has angles 7 whose number is equal to that of the plates 6 and whose wings define between them angles equal to 360 ° divided by this number. Anyway, the assembly by superposition of the wings of the angles 7 and by bolting of these wings is similar to the previous cases.

Comme décrit ci-avant, chaque extrémité de chaque membrure 5 est équipée d'un tenon formé par un plat 6 et une cornière 7, ce tenon soudé formant un prisme creux et rigide, de section transversale triangulaire et isocèle. Cette façon de réaliser un tel prisme rigide à l'aide du plat 6 et de la cornière 7 est pratique, rapide et rationnelle, mais elle pourrait être différente. Dans cet ordre d'idées, le prisme rigide pourrait être obtenu par soudure de trois plats soudés le long de leurs bords disposés deux à deux l'un près de l'autre. Il est à noter que pour augmenter la résistance du prisme, la cornière est renforcée à mi-hauteur par un raidisseur triangulaire soudé à ses ailes et au plat.As described above, each end of each frame 5 is equipped with a tenon formed by a flat 6 and an angle 7, this welded tenon forming a hollow and rigid prism, of triangular and isosceles cross section. This way of making such a rigid prism using the plate 6 and the angle iron 7 is practical, rapid and rational, but it could be different. In this connection, the rigid prism could be obtained by welding three plates welded along their edges arranged two by two close to each other. It should be noted that to increase the resistance of the prism, the angle is reinforced at mid-height by a triangular stiffener welded to its wings and flat.

Il est évident aue l'invention n'est pas exclusivement limitée aux formes de réalisation représentées et que bien des modifications peuvent être apportées dans la forme, la disposition et la constitution de certains des éléments intervenant dans leur réalisation pourvu que ces modifications ne soient pas en contradiction avec l'objet des revendications.It is obvious that the invention is not exclusively limited to the embodiments shown and that many modifications can be made in the form, arrangement and constitution of some of the elements involved in their achievement provided that these modifications are not inconsistent with the subject of the claims.
