Abstract

An expandable and collapsible structure, used for example as a portable modular stall, comprises juxtaposed mobile cross members (2) arranged in horizontal and vertical planes, each consisting of two bars (3) linked by a pin (4). The cross members (2) are joined together by means of connectors (5, 5') which hingedly link the ends of said bars (3) together. The structure comprises means for varying the spacing between the pins (4) of the cross members (2) in at least one horizontal or vertical series of cross members, and at least one connector (5, 5') corresponding to one of the ends of said cross members. Spacing can be varied by means of links (20) at the ends of the bars (3) making said ends telescopic. The general shape of the structure can thus be modified while still retaining its collapsible nature.

Les documents EP-A-0 353 999 et US-A-4 809 471 concernent des systèmes constitués d'une juxtaposition de croisillons mobiles, disposés dans des plans horizontaux et verticaux. Chaque croisillon est forme de deux tiges reliées par un axe central ; les différents plans horizontaux, constitués d'une suite linéaire de croisillons, sont reliés les uns aux autres par des plans verticaux de croisillons, qui sont parallèles les uns aux autres et qui sont disposés transversalement par rapport auxdits plans horizontaux.The documents EP-A-0 353 999 and US-A-4 809 471 relate to systems consisting of a juxtaposition of movable cross-pieces, arranged in horizontal and vertical planes. Each cross is formed by two rods connected by a central axis; the different horizontal planes, consisting of a linear series of cross-pieces, are connected to each other by vertical planes of cross-pieces, which are parallel to each other and which are arranged transversely with respect to said horizontal planes.
Les croisillons sont assemblés les uns aux autres au moyen de noeuds de connexion qui relient de façon articulée l'extrémité des tiges ; les connecteurs comportent de 0 préférence des bras de verrouillage qui relient les faces avant et arrière en vis à vis de la structure.The braces are assembled to each other by means of connection nodes which articulate the end of the rods; the connectors preferably comprise 0 locking arms which connect the front and rear faces opposite the structure.
Ces structures peuvent être éventuellement habillées au moyen d'accessoires ou de panneaux, fixés par des systèmes simples, du type magnétiques, autoagrippants 5 , ou autres. Une fois déployées, elles se présentent, vues de dessus, soit rectilignes, soit concaves ; les noeuds de connexion se situent sur les faces avant et arrière, dans deux plans rectilignes ou courbes, parallèles.These structures can possibly be dressed by means of accessories or panels, fixed by simple systems, of the magnetic type, hook-and-loop fasteners 5, or others. Once deployed, they appear, seen from above, either straight or concave; the connection nodes are located on the front and rear faces, in two rectilinear or curved planes, parallel.
Ces systèmes présentent l'inconvénient de ne pouvoir 0 évoluer qu'en largeur ou en longueur, en fonction de la position respective des tiges des croisillons ; leur rigidité linéaire ne permet pas une évolution de leur forme générale, vue de dessus, c'est-à-dire dans le plan d ' exposition. *5 On connaît é.galement, par le documentThese systems have the drawback of being able to move only in width or in length, depending on the respective position of the cross rods; their linear rigidity does not allow an evolution of their general shape, seen from above, that is to say in the exhibition plan. * 5 One also knows, by the document
US-A-4 290 244, des structures autoporteuses repliables, constituées de croisillons articulés reliés les uns aux autres au moyen de connecteurs internes et externes. Ces structures sont de forme sphérique ou en forme d'arche ; la forme correspondante est obtenue par des longueurs de tiges appropriées.US-A-4 290 244, collapsible self-supporting structures, consisting of articulated cross-braces connected to each other by means of internal and external connectors. These structures are spherical or arched; the corresponding shape is obtained by suitable rod lengths.
Pour faciliter et mieux contrôler le pliage et le dépliage, il est proposé d'alterner des croisillons à axe fixe et des croisillons munis de tiges à mouvement coulissant limité, associées à des ressorts de rappel.To facilitate and better control folding and unfolding, it is proposed to alternate braces with a fixed axis and braces provided with rods with limited sliding movement, associated with return springs.
Ces moyens particuliers permettent simplement d'éviter les problèmes de torsion des tiges lors des opérations ponctuelles de déploiement et de repliage de la structure.These particular means simply make it possible to avoid the problems of torsion of the rods during specific operations of deployment and folding of the structure.
Ils ne sont efficaces et ne sont utilisés qu'au cours de ces opérations ponctuelles et ils agissent par interactions des éléments les uns par rapport aux autres.They are effective and are used only during these specific operations and they act by interactions of the elements with respect to each other.
Là encore, ce genre de structure a une forme non évolutive, figée et définie d'emblée par la longueur des tiges des croisillons.Again, this kind of structure has a non-evolving shape, fixed and defined immediately by the length of the rods of the braces.
Le but de la présente invention est de perfectionner ces structures en vue de permettre l'obtention d'une évolution de leur forme générale, tout en leur conservant une fonction pliable. La possibilité de faire évoluer cette forme, vue de dessus, permet une plus grande souplesse d'utilisation de ce type de matériel.The object of the present invention is to improve these structures in order to allow an evolution of their general shape to be obtained, while retaining a foldable function for them. The possibility of changing this shape, seen from above, allows greater flexibility in the use of this type of material.
Cette structure déployable et repliable, par exemple pour la réalisation d'un stand, est du type constituée d'une juxtaposition de croisillons mobiles, disposés dans des plans horizontaux et verticaux, et formés chacun de deux tiges reliées par un axe. Ces croisillons sont assemblés les uns aux autres au moyen de connecteurs qui relient de façon articulée les extrémités desdites tiges.This deployable and collapsible structure, for example for the production of a stand, is of the type consisting of a juxtaposition of movable braces, arranged in horizontal and vertical planes, and each formed of two rods connected by an axis. These braces are assembled to each other by means of connectors which articulate the ends of said rods.
Selon l'invention, la structure comporte des moyens qui permettent de faire varier la distance entre l'axe des croisillons d'au moins une série horizontale ou verticale de croisillons et au moins. un connecteur correspondant à l'une des extrémités desdits croisillons, de façon à permettre une modification stable de la forme et de la présentation de la structure.According to the invention, the structure comprises means which make it possible to vary the distance between the axis of the braces of at least one horizontal or vertical series of braces and at least. a connector corresponding to one of the ends of said crosspieces, so as to allow a stable modification of the shape and presentation of the structure.
Ces caractéristiques permettent à une même structure d'être positionnée de façon rectiligne ou courbe, à volonté, selon les caractéristiques structurelles dont on dispose.These characteristics allow the same structure to be positioned in a rectilinear or curved manner, at will, according to the structural characteristics available.
Les faces parallèles avant et arrière peuvent consister, vues de dessus, en des lignes continues courbes ou en une succession de plans sécants ; les lignes horizontales de noeuds de connexion sont alors brisées.The front and rear parallel faces may consist, seen from above, of curved continuous lines or of a succession of intersecting planes; the horizontal lines of connection nodes are then broken.
Après déploiement droit, l'orientation des séries horizontales ou verticales de croisillons peut être réalisée selon les désirs et il est ainsi notamment possible d'habiller des angles de pièces d'une façon plus commode et plus esthétique qu'avec les structures de l'état de la technique.After straight deployment, the orientation of the horizontal or vertical series of braces can be carried out as desired and it is thus in particular possible to dress the angles of the rooms in a more convenient and more aesthetic way than with the structures of the state of the art.
La variation de distance entre les axes de croisillons et les connecteurs d'extrémité peut être réalisée soit par déplacement de l'axe sur la longueur de tiges fixes, soit par une variation de la longueur des tiges entre l'axe et le connecteur.The variation in distance between the spider axes and the end connectors can be carried out either by displacement of the axis over the length of fixed rods, or by a variation of the length of the rods between the axis and the connector.
Selon un mode de réalisation préféré, la structure comporte au moins une série horizontale ou verticale de croisillons, dont au moins une des tiges comporte au moins une extrémité télescopique permettant la variation de distance entre l'axe des croisillons et le connecteur d'extrémité correspondant. La structure comporte alors de préférence au moins une tige en forme de coulisse, dont au moins une des extrémités est munie d'une biellette formant coulisseau, pour rendre ladite extrémité télescopique .According to a preferred embodiment, the structure comprises at least one horizontal or vertical series of crosspieces, at least one of the rods of which comprises at least one telescopic end allowing the variation of distance between the axis of the crosspieces and the corresponding end connector . The structure then preferably comprises at least one rod in the form of a slide, at least one of the ends of which is provided with a rod forming a slide, to make said end telescopic.
Selon une autre disposition de l'invention, l'une des extrémités de la biellette coopère avec une butée disposée dans la coulisse pour limiter la course en extension.According to another arrangement of the invention, one of the ends of the link cooperates with a stop disposed in the slide to limit the stroke in extension.
Selon un mode de réalisation préféré et en vue de rendre la structure aisément manipulable et portable, les tiges et les biellettes associées sont réalisées en matériau léger tel qu'en aluminium ou en fibre de carbone. Selon une forme de réalisation particulière, la structure comporte des moyens qui permettent de faire varier la distance entre l'axe de la série verticale de croisillons d'extrémité et le connecteur intérieur arrière correspondant. On dispose alors d'une structure dont les extrémités latérales peuvent être ramenées vers l'avant.According to a preferred embodiment and in order to make the structure easy to handle and portable, the rods and the associated rods are made of light material such as aluminum or carbon fiber. According to a particular embodiment, the structure comprises means which make it possible to vary the distance between the axis of the vertical series of end braces and the rear interior connector corresponding. We then have a structure whose lateral ends can be brought forward.
Selon une autre disposition, on dispose de moyens qui permettent de faire varier la distance entre l'axe de toutes les séries verticales de croisillons et tous les connecteurs arrière. Ce type de structure peut ainsi définir à volonté une forme concave, vue de dessus.According to another arrangement, there are means which make it possible to vary the distance between the axis of all the vertical series of spiders and all the rear connectors. This type of structure can thus define at will a concave shape, seen from above.
Une autre forme de réalisation consiste à prévoir des moyens qui permettent de faire varier la distance entre l'axe de toutes les séries verticales de croisillons et tous les connecteurs de la structure. A partir d'une structure linéaire dépliée, on peut alors obtenir des formes concaves ou convexes, selon les désirs. La structure dispose également ainsi de moyens permettant son extension notable en longueur.Another embodiment consists in providing means which make it possible to vary the distance between the axis of all the vertical series of braces and all the connectors of the structure. From an unfolded linear structure, we can then obtain concave or convex shapes, as desired. The structure also thus has means allowing its notable extension in length.
Toujours selon l'invention, la structure peut comporter des moyens qui permettent de faire varier la distance entre l'axe de l'ensemble des croisillons et de tous les connecteurs associés. Le dispositif obtenu peut alors, une fois déplié, être manipulé dans tous les sens, dans un plan horizontal ou vertical.Still according to the invention, the structure may include means which make it possible to vary the distance between the axis of all the cross-braces and of all the associated connectors. The device obtained can then, once unfolded, be manipulated in all directions, in a horizontal or vertical plane.
Mais l'invention sera encore illustrée, sans être aucunement limitée par la description suivante d'un mode de réalisation particulier, donné à titre d'exemple et représenté sur les dessins annexés, dans lesquels :However, the invention will be further illustrated, without being in any way limited by the following description of a particular embodiment, given by way of example and shown in the appended drawings, in which:

Telle qu'on l'a représentée sur la figure 1, la structure 1 consiste en une association de croisillonsAs shown in Figure 1, the structure 1 consists of a combination of braces
2 constitués chacun de deux tiges 3 croisées, reliées par un axe 4, par exemple en forme de rivet, qui permet leur articulation. Les croisillons 2 sont assemblés les uns aux autres au moyen de noeuds de connexion ou connecteurs 5, 5' dont la structure sera détaillée plus loin. Les connecteurs 5, 5' relient les extrémités des tiges 3, de façon articulée ; ils sont disposés dans deux plans avant et arrière parallèles et définissent des lignes de connexion horizontales et verticales. Pour mieux comprendre la représentation schématique de la figure 1, les croisillons 2 disposés horizontalement ont été représentés en traits forts ; les croisillons verticaux sont représentés en traits plus fins. Les connecteurs 5, 5' sont indiqués par un point.2 each consisting of two crossed rods 3, connected by an axis 4, for example in the form of a rivet, which allows their articulation. The cross-pieces 2 are assembled to each other by means of connection nodes or connectors 5, 5 ′, the structure of which will be detailed below. The connectors 5, 5 'connect the ends of the rods 3, in an articulated manner; they are arranged in two parallel front and rear planes and define horizontal and vertical connecting lines. To better understand the schematic representation of Figure 1, the braces 2 arranged horizontally have been shown in strong lines; the vertical braces are shown in finer lines. The connectors 5, 5 'are indicated by a point.
Le mode de réalisation représenté est déployé linéairement ; il comporte quatre séries verticales 6, 7, 8 et 9 de croisillons constituées chacune de quatre croisillons 2 superposés qui définissent, par groupes, des plans horizontaux ; la structure comporte également trois séries horizontales 10, 11 et 12 de croisillons disposés verticalement, qui relient les plans horizontaux précédemment définis. Les croisillons des séries horizontales 10, 11 et 12 définissent, par groupes, des plans verticaux qui sont parallèles les uns aux autres et qui sont disposés transversalement par rapport auxdits plans horizontaux.The embodiment shown is deployed linearly; it comprises four vertical series 6, 7, 8 and 9 of cross-pieces each consisting of four superimposed cross-pieces 2 which define, in groups, horizontal planes; the structure also includes three horizontal series 10, 11 and 12 of vertically arranged braces, which connect the previously defined horizontal planes. The cross-pieces of the horizontal series 10, 11 and 12 define, in groups, vertical planes which are parallel to each other and which are arranged transversely with respect to said horizontal planes.
La structure ainsi formée peut être repliée par pivotement des tiges 3 autour de leur axe 4 pour prendre un encombrement très réduit qui facilite le transport. Selon l'invention, cette structure comporte des moyens qui permettent à un utilisateur de faire varier la distance entre l'axe 4 des croisillons 2 d'au moins une série verticale 6, 7, 8, 9 ou horizontale 10, 11, 12 de croisillons et au moins un connecteur 5, 5' qui correspond à l'une des extrémités desdits croisillons 2.The structure thus formed can be folded by pivoting the rods 3 around their axis 4 to take up a very small footprint which facilitates transport. According to the invention, this structure comprises means which allow a user to vary the distance between the axis 4 of the cross-pieces 2 of at least one vertical series 6, 7, 8, 9 or horizontal 10, 11, 12 of cross-pieces and at least one connector 5, 5 'which corresponds to one of the ends of said cross-pieces 2.
Ces moyens permettent par exemple, à partir de la structure déployée linéairement, représentée figure 1, d'obtenir la structure de la figure 2, dans laquelle on a fait évoluer les positions respectives dans l'espace des différentes séries verticales 6, 7, 8 et 9 de croisillons 2.These means make it possible, for example, from the structure deployed linearly, shown in FIG. 1, to obtain the structure of FIG. 2, in which the respective positions in the space of the different vertical series 6, 7, 8 have been changed. and 9 cross bars 2.
Un exemple de réalisation d'un connecteur 5, 5' qui permet de relier les extrémités des tiges 3 est représenté en perspective figure 3, et, de façon isolée, figures 4 et 5. Ce connecteur est constitué d'une platine 13 de forme sensiblement carrée et munie, sur sa face avant, de quatre éléments 14 en forme de U servant de chape, destinés chacun à recevoir l'extrémité d'une tige 3. Chaque élément 14 forme un logement pour les extrémités desdites tiges 3 ; ils sont principalement constitués de deux flasques latéraux 15 qui supportent l'axe 16, lequel permet l'articulation des tiges. Les éléments 14 peuvent être réalisés de façon monobloc avec la platine 13, par moulage de matériau plastique.An exemplary embodiment of a connector 5, 5 ′ which makes it possible to connect the ends of the rods 3 is shown in perspective in FIG. 3, and, in isolation, FIGS. 4 and 5. This connector consists of a plate 13 of shape substantially square and provided, on its front face, with four U-shaped elements 14 serving as a yoke, each intended to receive the end of a rod 3. Each element 14 forms a housing for the ends of said rods 3; they mainly consist of two lateral flanges 15 which support the axis 16, which allows the articulation of the rods. The elements 14 can be produced in a single piece with the plate 13, by molding of plastic material.
Les quatre éléments 14 sont disposés en bordure de chacun des côtés de la platine 13. Les deux éléments 14 disposés latéralement sont destinés à recevoir les extrémités de tiges 3 qui s'étendent dans un plan sensiblement horizontal ; les éléments 14 haut et bas reçoivent, eux, les extrémités des tiges 3 qui s'étendent dans un plan vertical. Les éléments 14 en vis à vis sur chaque côté sont décalés l'un par rapport à l'autre de façon à ce que les tiges 3 associées soient décalée lors du repliement. Chaque couple de flasques 15 en vis à vis est disposé de telle sorte que l'un des côtés des tiges 3 soit disposé sur l'axe médian 17 de la platine 13, tout comme la face opposée de la tige 3 en vis à vis ; la face interne 15' des flasques 15 centraux est disposée sur ledit axe médian 17.The four elements 14 are arranged at the edge of each of the sides of the plate 13. The two elements 14 arranged laterally are intended to receive the ends of rods 3 which extend in a substantially horizontal plane; the top and bottom elements 14 receive the ends of the rods 3 which extend in a vertical plane. The elements 14 opposite on each side are offset with respect to each other so that the associated rods 3 are offset during folding. Each pair of flanges 15 facing each other is arranged so that one of the sides of the rods 3 is disposed on the median axis 17 of the plate 13, just like the opposite face of the rod 3 opposite; the internal face 15 ′ of the central flanges 15 is disposed on said median axis 17.
Les orifices 18 prévus dans les flasques 15 permettent la réception de tourillons ou de vis de fixation des extrémités des tiges 3, lesquels matérialisent l'axe de rotation 16.The orifices 18 provided in the flanges 15 allow the reception of pins or screws for fixing the ends of the rods 3, which materialize the axis of rotation 16.
La platine 13 est encore munie, en son centre, d'un orifice 19 destiné à la réception de bras de verrouillage 5 disposés judicieusement de place en place pour améliorer la tenue et la rigidité de l'ensemble.The plate 13 is also provided, in its center, with an orifice 19 intended for the reception of locking arms 5 judiciously arranged from place to place to improve the strength and the rigidity of the assembly.
Dans l'exemple de réalisation représenté, les tiges 3 consistent en des profilés de section carrée creuse obtenus en matériau léger du type aluminium ou fibres 0 de carbone .In the embodiment shown, the rods 3 consist of hollow square section profiles obtained from light material of the aluminum or carbon fiber 0 type.
Tel qu'on peut le voir sur la figure 3, les tiges 3 horizontales, en vis à vis, sont associées à des biellettes d'extrémité 20 qui forment coulisseau et qui permettent par prolongement, une variation de leur longueur. L'une des extrémités de ces biellettes 20 est fixée de façon rotative sur les flasques 15 des éléments 14 par un moyen quelconque du type rivet ou vis ; l'autre extrémité s'engage dans la tige 3 creuse et a la possibilité de coulisser pour rendre cette dernière υ télescopique.As can be seen in FIG. 3, the horizontal rods 3, facing each other, are associated with end links 20 which form a slide and which allow, by extension, a variation in their length. One of the ends of these links 20 is rotatably attached to the flanges 15 of the elements 14 by any means of the rivet or screw type; the other end engages in the hollow shaft 3 and has the ability to slide to make the latter telescopic υ.
Tel qu'on l'a représenté sur la figure 6, la bielletteAs shown in Figure 6, the link
20 consiste en un profilé aluminium de forme générale en U par exemple et muni, à son extrémité libre, de deux orifices 21 qui permettent son ancrage de façon rotative sur les flasques 15. Cette même extrémité comporte également un épaulement 22 qui forme arrêtoir pour l'extrémité de la tige 3 représentée en traits mixtes fins. L'autre extrémité de la biellette 20 comporte un retour en équerre 23 destiné à coopérer avec une butée20 consists of an aluminum profile of general U-shape for example and provided, at its free end, with two orifices 21 which allow it to be anchored in a rotary manner on the flanges 15. This same end also includes a shoulder 22 which forms a stop for the end of the rod 3 shown in thin broken lines. The other end of the rod 20 has a return square 23 intended to cooperate with a stop
24 prévue dans la tige 3, pour limiter la course du 0 coulisseau 20 dans la coulisse 3. La butée 24 peut notamment être obtenue au moyen d'un rivet fixé dans un orifice prévu sur l'une des faces de la tige 3 et qui pénètre dans ladite tige d'une longueur adaptée pour C coopérer avec le retour 23. Cette butée 24 est disposée sur la tige 3 en fonction de la longueur de la biellette 20 et selon la course télescopique désirée.24 provided in the rod 3, to limit the stroke of the slide 20 in the slide 3. The stop 24 can in particular be obtained by means of a rivet fixed in an orifice provided on one of the faces of the rod 3 and which penetrates into said rod of a length suitable for C to cooperate with the return 23. This stop 24 is disposed on the rod 3 as a function of the length of the rod 20 and according to the desired telescopic stroke.
La possibilité d'extension de la longueur des tiges 3 permet de faire varier la position de l'axe de rotationThe possibility of extending the length of the rods 3 allows the position of the axis of rotation to be varied
4 du croisillon correspondant, par rapport au connecteur4 of the corresponding spider, relative to the connector
5 associé .5 associated.
On comprend bien que si l'on dispose de telles caractéristiques sur toute une ligne horizontale ou verticale de connexion, on va pouvoir faire varier les positions respectives dans l'espace des séries correspondantes horizontales ou verticales de croisillons.It will be understood that if such characteristics are available over a whole horizontal or vertical connection line, it will be possible to vary the respective positions in the space of the corresponding horizontal or vertical series of braces.
Une telle réalisation est représentée vue de dessus sur la figure 7. Cette figure montre, à partir d'une rangée linéaire horizontale de quatre croisillons représentés en pointillés, une possibilité de modification de la forme d'ensemble par une extension des biellettes télescopiques 20.Such an embodiment is shown seen from above in FIG. 7. This figure shows, from a horizontal linear row of four braces represented in dotted lines, a possibility of modification of the overall shape by an extension of the telescopic links 20.
Dans cet exemple de réalisation, tous les connecteurs 5, 5' situés dans le plan arrière de la structure supportent des tiges horizontales 3 munies de biellettes 20. Il est alors possible d'orienter les séries de croisillons dans un sens, et en l'occurence vers l'avant, les unes par rapport aux autres, pour obtenir la forme représentée, en arc de cercle. On obtient une forme concave, stable, dans laquelle les différentes lignes horizontales de connecteurs 5, 5' sont courbes.In this exemplary embodiment, all of the connectors 5, 5 ′ located in the rear plane of the structure support horizontal rods 3 provided with rods 20. It is then possible to orient the series of cross-pieces in one direction, and in the occur forward, relative to each other, to obtain the shape shown, in an arc. A stable, concave shape is obtained, in which the different horizontal lines of connectors 5, 5 'are curved.
Le retour à la position linéaire de départ, pour le repliement de la structure par exemple, s'effectue très facilement en rentrant les séries de biellettes 20 à l'intérieur des tiges 3 correspondantes.The return to the starting linear position, for the folding of the structure for example, is carried out very easily by entering the series of rods 20 inside the corresponding rods 3.
On peut noter sur cette figure, la présence de deux bras de verrouillage 25, représentés en traits mixtes fins et positionnés au niveau des extrémités de la structure .It can be noted in this figure, the presence of two locking arms 25, shown in thin broken lines and positioned at the ends of the structure.
Dans un autre mode de réalisation, seules les séries verticales 6 et 9 de croisillons d'extrémité sont aptes à s'orienter par rapport au reste de la structure. Les tiges horizontales 3 peuvent alors comporter des biellettes 20 associées aux connecteurs intérieurs arrière 5'. Cette caractéristique permet d'habiller plus aisément les angles de pièces par exemple. Dans d'autres modes de réalisation, toutes les tigesIn another embodiment, only the vertical series 6 and 9 of end braces are able to orient themselves relative to the rest of the structure. The horizontal rods 3 can then comprise connecting rods 20 associated with the rear interior connectors 5 ′. This characteristic makes it easier to dress the corners of rooms, for example. In other embodiments, all of the rods
3 horizontales sont munies de moyens d'extension 20. On peut alors définir des formes concaves ou convexes selon les désirs ou les nécessités et contraintes spatiales. Pour augmenter encore les possibilités d'évolution, les tiges 3 qui s'étendent dans les plans verticaux peuvent aussi comporter des biellettes 20.3 horizontal ones are provided with extension means 20. It is then possible to define concave or convex shapes according to the desires or the needs and spatial constraints. To further increase the possibilities of evolution, the rods 3 which extend in the vertical planes can also include rods 20.
L'utilisation et le positionnement de ces caractéristiques sont choisis selon les modifications de structures que l'on veut obtenir.The use and positioning of these characteristics are chosen according to the structural modifications which it is desired to obtain.
Les signes de référence insérés après les caractéristiques techniques mentionnées dans les revendications ont pour seul but de faciliter la compréhension de ces dernières et n'en limitent aucunement la portée . The reference signs inserted after the technical characteristics mentioned in the claims are intended only to facilitate the understanding of the latter and in no way limit their scope.
