Description

La présente invention concerne un ensemble pour une grille barreaudée, un outil pour l'assemblage d'un tel ensemble, ainsi qu'une grille barreaudée comprenant au moins un tel ensemble.The present invention relates to an assembly for a barred grid, a tool for assembling such an assembly, and a barred grid comprising at least one such assembly.

L'invention s'applique donc à la conception et à la fabrication d'une grille barreaudée, ceci indépendamment de sa destination, par exemple que cette grille constitue un élément de clôture ou un élément de portail, voire une grille de protection de fenêtre ou autre.The invention therefore applies to the design and manufacture of a grid bar, this regardless of its destination, for example that this grid is a fence element or a gate element, or a window protection grille or other.

Une grille barreaudée est généralement constituée de barreaux sensiblement verticaux et de barreaux sensiblement horizontaux également appelés "lisses". Les barreaux verticaux sont disposés à une certaine distance les uns des autres et les lisses sont disposées transversalement par rapport aux barreaux verticaux. Pour solidariser un barreau vertical et une lisse, ceux-ci sont généralement soudés. Cette ligne de soudure doit ensuite être peinte. Cette ligne de soudure qui forme un bourrelet génère un défaut d'esthétisme, ainsi qu'une zone de faiblesse mécanique. En particulier, après sa mise en place, une clôture constituée d'une telle grille barreaudée peut subir des efforts qui peuvent détériorer les lignes de soudure.A grid rod is generally constituted by substantially vertical bars and substantially horizontal bars also called "smooth". The vertical bars are arranged at a distance from each other and the rails are arranged transversely relative to the vertical bars. To secure a vertical bar and a bar, they are usually welded. This weld line must then be painted. This weld line that forms a bead generates a lack of aesthetics, as well as a zone of mechanical weakness. In particular, after its installation, a fence consisting of such a grid rod may suffer efforts that can deteriorate the weld lines.

On connaît également les techniques décrites par les documents WO-97/11241 , US-4 982 932 , US-4 846 600 et FR-626 176 qui concernent des modes d'assemblage d'un barreau horizontal sur un barreau vertical ou la technique décrite par le document US-3 861 274 qui concerne un outil pour le montage d'une clôture.The techniques described by the documents are also known WO-97/11241 , U.S. 4,982,932 , U.S. 4,846,600 and FR-626 176 which concern modes of assembly of a horizontal bar on a vertical bar or the technique described by the document U.S. 3,861,274 concerning a tool for mounting a fence.

Un objet de la présente invention est de proposer un ensemble pour une grille barreaudée qui ne présente pas les inconvénients de l'art antérieur.An object of the present invention is to provide an assembly for a bar grid which does not have the drawbacks of the prior art.

A cet effet, est proposé un ensemble pour une grille barreaudée conforme à la revendication 1.For this purpose, there is provided an assembly for a bar grating according to claim 1.

Avantageusement, lorsque le barreau horizontal ou la lisse est emboîté dans le barreau vertical, l'axe du trou est sensiblement parallèle à l'axe du barreau vertical.Advantageously, when the horizontal bar or the bar is fitted into the vertical bar, the axis of the hole is substantially parallel to the axis of the vertical bar.

Avantageusement, le moyen de solidarisation est un clou ou une vis ou une goupille ou tout dispositif comportant un axe.Advantageously, the securing means is a nail or a screw or a pin or any device having an axis.

Selon une solution avantageuse, lesdits moyens de blocage appartiennent au groupe suivant :

  • filetage ménagé sur ledit axe et destiné à venir en contact avec une surface intérieure dudit barreau vertical et/ou avec ledit barreau horizontal au niveau dudit trou;
  • au moins un cran destiné à venir en contact avec une surface intérieure dudit barreau vertical et/ou avec ledit barreau horizontal au niveau dudit trou.
According to an advantageous solution, said blocking means belong to the following group:
  • threading formed on said axis and intended to come into contact with an inner surface of said vertical bar and / or with said horizontal bar at said hole;
  • at least one notch intended to come into contact with an inner surface of said vertical bar and / or with said horizontal bar at said hole.

Une telle solution s'avère suffisamment efficace pour assurer le blocage en position de l'axe dans le trou du barreau horizontal, ceci en particulier lorsque la grille est destinée à constituer un élément de clôture.Such a solution is sufficiently effective to ensure the blocking position of the axis in the hole of the horizontal bar, this in particular when the grid is intended to constitute a fence element.

En effet, une fois la grille montée en tant qu'élément de clôture, celle-ci est fixe et n'est sujette qu'à des sollicitations rares et/ou de faible intensité. En conséquence, il est très peu probable que les chocs et/ou vibrations susceptibles de s'exercer sur la clôture soient suffisantes pour provoquer un retrait progressif de l'axe à partir du trou du barreau horizontal.Indeed, once the gate mounted as a closing element, it is fixed and is subject only to rare and / or weak solicitations. intensity. Consequently, it is very unlikely that the shocks and / or vibrations likely to be exerted on the fence are sufficient to cause a gradual withdrawal of the axis from the hole of the horizontal bar.

Cette analyse connaît un intérêt particulier dans la mesure où, comme cela va apparaître plus clairement par la suite, le montage d'une grille selon l'invention est réalisé en particulier en vue d'assembler deux barreaux horizontaux (ou lisses) sur une pluralité de barreaux verticaux. Dans ce cas, l'un des axes est introduit par l'une des extrémités du barreau vertical, tandis que l'autre axe est introduit par l'extrémité opposée du barreau vertical. On comprend alors que l'un des axes (celui introduit par le haut), sous l'effet de la gravité combinée à d'éventuelles vibrations, est peu enclin à se retirer du trou du barreau horizontal correspondant. En revanche, l'axe introduit par l'extrémité inférieure du barreau vertical tendrait à se retirer progressivement du trou du barreau horizontal correspondant sous l'effet de vibrations combinées à l'effet de la gravité.This analysis is of particular interest insofar as, as will become clearer later, the assembly of a grid according to the invention is made in particular to assemble two horizontal bars (or smooth) on a plurality of vertical bars. In this case, one of the axes is introduced by one of the ends of the vertical bar, while the other axis is introduced by the opposite end of the vertical bar. It is understood that one of the axes (the one introduced from above), under the effect of gravity combined with possible vibrations, is reluctant to withdraw from the hole of the corresponding horizontal bar. On the other hand, the axis introduced by the lower end of the vertical bar would tend to gradually withdraw from the hole of the corresponding horizontal bar under the effect of vibrations combined with the effect of gravity.

Les moyens de blocage listés précédemment sont donc suffisamment efficaces pour une grille destinée à constituer un élément de clôture.The blocking means listed above are therefore sufficiently effective for a grid intended to constitute a closing element.

En revanche, si la grille est destinée à constituer un élément d'un ensemble mobile, tel que c'est le cas lorsque la grille selon l'invention est un élément de portail par exemple, la mobilité de l'ensemble dans lequel est intégrée la grille peut engendrer des vibrations répétées, voire régulières.On the other hand, if the grid is intended to constitute an element of a mobile assembly, as is the case when the grid according to the invention is a portal element for example, the mobility of the assembly in which is integrated the grid can generate repeated vibrations, even regular.

Il peut alors être nécessaire de prévoir des moyens de blocage autres que ceux listés précédemment et/ou additionnels de ceux-ci.It may then be necessary to provide locking means other than those listed above and / or additional thereof.

Selon l'invention, lesdits moyens de blocage comprennent avantageusement un élément déformable destiné à être monté en force contre une surface intérieure du barreau vertical, de façon à s'opposer au retrait dudit axe à partir dudit trou.According to the invention, said locking means advantageously comprise a deformable element intended to be mounted in force against an inner surface of the vertical bar, so as to oppose the withdrawal of said axis from said hole.

Ainsi, la mise en place de l'axe dans le trou correspondant s'opère selon une direction d'introduction qui engendre le montage à force de l'élément déformable contre la surface intérieure du barreau vertical, et l'élément déformable une fois déformé exerce un effort sur l'axe qui s'oppose aux contraintes (et/ou absorbe ces contraintes) s'exerçant sur l'axe dirigées selon une direction opposée à la direction d'introduction.Thus, the establishment of the axis in the corresponding hole takes place in a direction of introduction which causes the force of the deformable element against the inner surface of the vertical bar, and the deformable element once deformed exerts a force on the axis which opposes the stresses (and / or absorbs these stresses) exerted on the axis directed in a direction opposite to the direction of introduction.

Selon l'invention, ledit élément déformable prend la forme d'une extension radiale dudit axe destiné à s'écraser contre ladite surface intérieure.According to the invention, said deformable element takes the form of a radial extension of said axis intended to crash against said inner surface.

Selon une variante avantageuse, ledit élément déformable prend la forme d'une rondelle rapportée contre une butée solidaire dudit axe, ladite rondelle étant préférentiellement réalisée en un matériau élastiquement déformable.According to an advantageous variant, said deformable element takes the form of a washer attached to an abutment integral with said axis, said washer being preferably made of an elastically deformable material.

Selon cette variante, l'introduction de l'axe entraîne une déformation de la rondelle au contact de la surface intérieure du barreau vertical, la matière de la rondelle venant s'étendre entre la butée et la surface intérieure du barreau vertical. A ce stade, la matière élastiquement déformable de la rondelle prenant place entre la butée et la surface intérieure du barreau vertical exerce deux fonctions :

  • une fonction de réaction tendant à retenir l'axe selon une direction opposée à la direction d'introduction de l'axe ;
  • une fonction d'amortissement des vibrations susceptibles de s'exercer sur l'axe par l'intermédiaire de la surface du barreau vertical.
According to this variant, the introduction of the axis causes a deformation of the washer in contact with the inner surface of the vertical bar, the material of the washer extending between the stop and the inner surface of the vertical bar. At this stage, the elastically deformable material of the washer taking place between the stop and the inner surface of the vertical bar has two functions:
  • a reaction function tending to retain the axis in a direction opposite to the direction of introduction of the axis;
  • a vibration damping function that can be exerted on the axis via the surface of the vertical bar.

L'invention propose également un outil pour l'assemblage d'un ensemble selon l'une des variantes précédentes, caractérisé en ce qu'il comprend une extrémité d'insertion et un corps extérieur, l'extrémité d'insertion étant prévue pour pénétrer dans le barreau vertical et étant percée d'un alésage de guidage qui vient sensiblement s'aligner avec le trou débouchant, le corps extérieur étant disposé dans le prolongement de l'extrémité d'insertion, percé d'un alésage de poussée coaxial avec l'alésage de guidage, et muni d'un piston.The invention also proposes a tool for assembling an assembly according to one of the preceding variants, characterized in that it comprises an insertion end and an external body, the insertion end being designed to penetrate in the vertical bar and being pierced a guide bore which substantially aligns with the through hole, the outer body being disposed in the extension of the insertion end, pierced with a thrust bore coaxial with the guide bore, and provided with of a piston.

Avantageusement, l'extrémité d'insertion comprend une butée qui vient en appui contre l'extrémité du barreau vertical.Advantageously, the insertion end comprises a stop that abuts against the end of the vertical bar.

Avantageusement, l'extrémité libre de l'extrémité d'insertion est munie d'un moyen de guidage mobile en rotation autour d'un axe sensiblement orthogonal à l'axe de l'alésage de guidage.Advantageously, the free end of the insertion end is provided with a guide means movable in rotation about an axis substantially orthogonal to the axis of the guide bore.

L'invention propose également une grille barreaudée comprenant au moins un ensemble selon l'une des variantes précédentes.The invention also proposes a bar grating comprising at least one assembly according to one of the preceding variants.

Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d'autres, apparaîtront plus clairement à la lecture de la description suivante d'un exemple de réalisation, ladite description étant faite en relation avec les dessins joints, parmi lesquels :

The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of an exemplary embodiment, said description being given in relation to the attached drawings, among which:

La figure 1 représente un ensemble 100 pour une grille barreaudée. La grille barreaudée est ici représentée en position verticale, c'est-à-dire dans la position dans laquelle elle est placée pour réaliser un élément de clôture ou de portail. La grille barreaudée comprend un ensemble de barreaux verticaux 102 et un ensemble de barreaux horizontaux ou de lisses 104 qui se croisent. Le barreau vertical 102 est représenté comme étant vertical mais il peut présenter un certain angle avec la direction verticale et de la même manière, le barreau horizontal ou la lisse 104 est représenté(e) comme étant horizontal(e) et perpendiculaire au barreau vertical 102, mais il/elle peut présenter un angle différent, les différentes positions sont liées à l'esthétisme de la grille barreaudée.The figure 1 represents a set 100 for a bar grid. The bar grid is here represented in a vertical position, that is to say in the position in which it is placed to produce a fence or gate element. The bar grid comprises a set of vertical bars 102 and a set of horizontal bars or smooth 104 which intersect. The vertical bar 102 is shown as being vertical but may have an angle with the vertical direction and in the same manner, the horizontal bar or the bar 104 is shown as being horizontal (e) and perpendicular to the vertical bar 102, but he / she may have a different angle, the different positions are related to the aesthetics of the grid bar.

L'ensemble pour une grille barreaudée 100 comprend un barreau vertical 102, un barreau horizontal ou une lisse barreau 104, qui croise le barreau vertical 102, et un moyen de solidarisation 106.The assembly for a bar grid 100 comprises a vertical bar 102, a horizontal bar or a bar bar 104, which crosses the vertical bar 102, and a securing means 106.

Le barreau vertical 102 est creux et comporte une encoche 116 réalisée dans sa paroi. Cette encoche 116 est prévue pour recevoir le barreau horizontal ou la lisse 104. Les dimensions et la forme de l'encoche 116 sont adaptées à la forme et aux dimensions du barreau horizontal ou de la lisse 104. Le barreau horizontal ou la lisse 104 peut donc ainsi s'emboîter dans le barreau vertical 102.The vertical bar 102 is hollow and has a notch 116 formed in its wall. This notch 116 is provided to receive the horizontal bar or the bar 104. The dimensions and shape of the notch 116 are adapted to the shape and dimensions of the horizontal bar or the bar 104. The horizontal bar or the bar 104 can and thus fit into the vertical bar 102.

Le barreau horizontal ou la lisse 104 comprend un trou débouchant 110. Ici, le barreau horizontal ou la lisse 104 est creux, mais il peut être plein. Le trou 110 est dimensionné de manière à ce que chaque extrémité se trouve au moins en partie à l'intérieur du barreau vertical 102 lorsque le barreau horizontal ou la lisse 104 est emboîté dans le barreau vertical 102. Le trou 110 est de préférence cylindrique mais il peut prendre d'autres formes.The horizontal bar or the bar 104 comprises a through hole 110. Here, the horizontal bar or the bar 104 is hollow, but it can be full. The hole 110 is dimensioned so that each end is at least partly inside the vertical bar 102 when the horizontal bar or the bar 104 is fitted into the vertical bar 102. The hole 110 is preferably cylindrical but it can take other forms.

Lorsque le barreau horizontal ou la lisse 104 est emboîté dans le barreau vertical 102, l'axe du trou 110 est sensiblement parallèle à l'axe du barreau vertical 102.When the horizontal bar or the bar 104 is fitted into the vertical bar 102, the axis of the hole 110 is substantially parallel to the axis of the vertical bar 102.

Le moyen de solidarisation comprend un axe 106 dont la section permet sa pénétration dans le trou 110, et dont le profil longitudinal est tel que lorsqu'il est inséré dans le trou 110, l'axe 106 exerce, sur le barreau horizontal ou la lisse 104, une force de maintien F orientée vers l'intérieur du barreau vertical 102. La force de maintien F tend ainsi à plaquer le barreau horizontal ou la lisse 104 dans le fond de l'encoche 116.The securing means comprises an axis 106 whose section allows its penetration into the hole 110, and whose longitudinal profile is such that when inserted into the hole 110, the axis 106 exerts, on the horizontal bar or the smooth 104, a holding force F oriented towards the inside of the vertical bar 102. The holding force F thus tends to press the horizontal bar or the bar 104 into the bottom of the notch 116.

Pour exercer cette force de maintien F , le moyen de solidarisation 106 prend appui sur la surface intérieure de la paroi du barreau vertical 102. Un premier appui s'effectue ainsi en aval du trou 110 et un deuxième appui s'effectue ainsi en amont du trou 110.To exercise this sustaining force F , the securing means 106 is supported on the inner surface of the wall of the vertical bar 102. A first support is thus made downstream of the hole 110 and a second support is thus upstream of the hole 110.

Le moyen de solidarisation 106 exerce ainsi une force de pression sur la surface intérieure de la paroi du barreau vertical 102 et cette force de pression génère la force de maintien F .The securing means 106 thus exerts a pressing force on the inner surface of the wall of the vertical bar 102 and this pressure force generates the holding force F .

Le moyen de solidarisation 106 est poussé à l'intérieur du barreau vertical 102 et est entré en force à l'intérieur du trou 110 jusqu'à venir en contact de part et d'autre du trou contre la surface intérieure de la paroi du barreau vertical 102.The securing means 106 is pushed inside the vertical bar 102 and forced into the hole 110 until it comes into contact on either side of the hole against the inner surface of the bar wall. vertical 102.

Selon un mode de réalisation particulier, le moyen de solidarisation 106 prend la forme d'une vis ou d'un clou ou d'une goupille ou tout dispositif comportant un axe. La tête 108 de la vis ou du clou vient alors en appui, en amont du trou 110, contre la surface intérieure de la paroi du barreau vertical 102, la pointe vient alors en appui, en aval du trou 110, contre la surface intérieure de la paroi du barreau vertical 102.According to a particular embodiment, the securing means 106 takes the form of a screw or a nail or a pin or any device comprising an axis. The head 108 of the screw or nail then bears, upstream of the hole 110, against the inner surface of the wall of the vertical bar 102, the tip then bears, downstream of the hole 110, against the inner surface of the the wall of the vertical bar 102.

Pour assurer son blocage, lorsqu'il est en place, le moyen de solidarisation 106 comprend des moyens de blocage 114 qui viennent en contact avec la surface intérieure de la paroi du barreau vertical 102. Dans le cas d'une vis, les moyens de blocage 114 sont réalisés par le filetage de la vis. Dans le cas d'un clou, un clou à tige cranté peut être utilisé, les moyens de blocage 114 étant alors réalisés par les crans.To ensure its locking, when in place, the securing means 106 comprises locking means 114 which come into contact with the inner surface of the wall of the vertical bar 102. In the case of a screw, the means of blocking 114 are made by the thread of the screw. In the case of a nail, a notched pin nail can be used, the locking means 114 then being made by the notches.

On note que les moyens de blocage peuvent en plus (ou alternativement) coopérer avec le barreau horizontal 104, au niveau du trou 110. En effet, le filetage ou le(s) cran(s) peuvent être disposés sur le moyen de solidarisation de façon à venir en butée contre la paroi du barreau horizontal, et plus précisément au niveau de la paroi délimitant le trou 110.It should be noted that the blocking means can additionally (or alternatively) cooperate with the horizontal bar 104, at the level of the hole 110. Indeed, the thread or the notch (s) can be arranged on the securing means of way to abut against the wall of the horizontal bar, and more precisely at the wall defining the hole 110.

On note de plus que les moyens de blocage illustrés sur la figure 1 s'étendent seulement en partie basse et jusqu'à l'extrémité inférieure du moyen de solidarisation 106. Toutefois, les moyens de blocage peuvent s'étendre selon d'autres dispositions envisageables, par exemple seulement à partir d'une certaine hauteur du moyen de solidarisation et/ou jusqu'à la tête 108.It is further noted that the locking means illustrated on the figure 1 extend only in the lower part and up to the lower end of the securing means 106. However, the locking means may extend according to other conceivable arrangements, for example only from a certain height of the means. fastening and / or up to the head 108.

L'assemblage du barreau vertical 102 et du barreau horizontal ou de la lisse 104 à l'aide du moyen de solidarisation 106 est aisé. Il n'est pas nécessaire de repeindre l'ensemble 100 après l'assemblage car il n'y a pas de soudure. L'absence de ligne soudure évite l'apparition d'une zone de faiblesse même lorsque l'élément de clôture ou de portail subit des efforts.The assembly of the vertical bar 102 and the horizontal bar or the bar 104 with the securing means 106 is easy. It is not necessary to repaint the assembly 100 after assembly because there is no welding. The lack of welding line prevents the appearance of a weak area even when the fence or gate element is under stress.

Les figures 4 et 5 illustrent chacune une variante de réalisation d'une grille barreaudée selon l'invention.The figures 4 and 5 each illustrate an alternative embodiment of a bar grid according to the invention.

Tel que cela apparaît sur ces figures, la configuration de l'assemblage du barreau vertical 102 avec le barreau horizontal (ou lisse) 104 est réalisée à l'aide d'un moyen de solidarisation introduit dans le barreau vertical 102 selon une direction d'introduction dirigée vers le haut, c'est-à-dire en passant par l'ouverture de l'extrémité inférieure 1020 du barreau vertical 102.As it appears in these figures, the configuration of the assembly of the vertical bar 102 with the horizontal (or smooth) bar 104 is achieved by means of a securing means introduced into the vertical bar 102 in a direction of introduction directed upwards, that is to say through the opening of the lower end 1020 of the vertical bar 102.

Cela étant, l'ensemble pour grille barreaudée 100 décrit par ces figures présente, selon le principe de l'invention, les caractéristiques suivantes :

  • le barreau vertical 102 est creux et comporte une encoche 116 prévue pour recevoir le barreau horizontal 104, les dimensions et la forme de l'encoche étant adaptées à la forme et aux dimensions du barreau 104 en vue d'un emboîtement de ce dernier dans le barreau vertical 102 ;
  • le barreau horizontal 104 comprend un trou débouchant 110 dimensionné de manière à ce que chaque extrémité se trouve en partie à l'intérieur du barreau vertical 102 lorsque le barreau horizontal étant monté dans le barreau vertical, et l'axe du trou 110 étant sensiblement parallèle à l'axe du barreau vertical 102 ;
  • les moyens de solidarisation comprennent un axe 106 dont la section permet sa pénétration dans le trou 110, et dont le profil longitudinal est tel que lorsqu'il est inséré dans le trou 110, l'axe 106 exerce sur le barreau horizontal 104 une force de maintien orientée vers l'intérieur du barreau vertical 102 en vue de plaquer le barreau horizontal dans le fond de l'encoche 116, ceci du fait que les moyens de solidarisation 106 font appui sur la surface intérieure de la paroi du barreau vertical en aval et en amont du trou 110.
That being so, the set for barred grid 100 described by these figures has, according to the principle of the invention, the following characteristics:
  • the vertical bar 102 is hollow and has a notch 116 provided for receiving the horizontal bar 104, the dimensions and the shape of the notch being adapted to the shape and dimensions of the bar 104 to a nesting of the latter in the vertical bar 102;
  • the horizontal bar 104 comprises a through hole 110 dimensioned so that each end is partly inside the vertical bar 102 when the horizontal bar is mounted in the vertical bar, and the axis of the hole 110 is substantially parallel to the axis of the vertical bar 102;
  • the securing means comprise an axis 106 whose section allows it to penetrate the hole 110, and whose longitudinal profile is such that when it is inserted into the hole 110, the axis 106 exerts on the horizontal bar 104 a force of maintaining oriented towards the inside of the vertical bar 102 in order to press the horizontal bar into the bottom of the notch 116, this being because the securing means 106 bear on the inner surface of the wall of the vertical bar downstream and upstream of the hole 110.

Tel qu'illustré par les figures 4 et 5, les moyens de solidarisation ont la forme d'un dispositif comprenant un axe présentant :

  • une première extrémité 1060 correspondant à l'extrémité d'introduction du moyen de solidarisation, c'est-à-dire l'extrémité engagée en premier au travers du trou 110, cette extrémité venant et étant maintenue en appui contre la surface intérieure 1021 du barreau vertical 102 ;
  • une deuxième extrémité 1061 opposée à l'extrémité 1060.
As illustrated by figures 4 and 5 the securing means are in the form of a device comprising an axis having:
  • a first end 1060 corresponding to the insertion end of the securing means, that is to say the end engaged first through the hole 110, this end coming and being held in abutment against the inner surface 1021 of the vertical bar 102;
  • a second end 1061 opposite the end 1060.

On note que, de façon similaire au mode de réalisation illustré par la figure 1, l'extrémité 1060 du moyen de solidarisation peut présenter des moyens de blocage 114 prenant la forme soit d'un filetage (dans le cas où le moyen de solidarisation 106 prend la forme d'une vis) soit de crans (dans le cas où le moyen de solidarisation 106 prend la forme d'un clou).It is noted that, similarly to the embodiment illustrated by the figure 1 , the end 1060 of the securing means may have locking means 114 in the form of a thread (in the case where the securing means 106 takes the form of a screw) or notches (in the case where the securing means 106 takes the form of a nail).

Comme indiqué en référence à la figure 1, les moyens de blocage peuvent coopérer avec la surface intérieure du barreau vertical et/ou coopérer avec le barreau horizontal 104, au niveau du trou 110. En effet, le filetage ou le(s) cran(s) peuvent être disposés sur le moyen de solidarisation de façon à venir en butée contre la paroi du barreau horizontal, et plus précisément au niveau de la paroi délimitant le trou 110.As indicated with reference to the figure 1 , the locking means can cooperate with the inner surface of the vertical bar and / or cooperate with the horizontal bar 104, at the hole 110. Indeed, the thread or the (s) notch (s) can be arranged on the means fastening so as to abut against the wall of the horizontal bar, and more precisely at the wall delimiting the hole 110.

De plus, les moyens de blocage illustrés sur les figures 4 et 5 s'étendent seulement en partie haute et jusqu'à l'extrémité 1060 du moyen de solidarisation 106. Toutefois, les moyens de blocage peuvent s'étendre selon d'autres dispositions envisageables, par exemple seulement à partir d'une certaine hauteur du moyen de solidarisation (à partir de la première extrémité 1060) et/ou jusqu'à la deuxième extrémité 1061.In addition, the locking means illustrated on the figures 4 and 5 extend only in the upper part and up to the end 1060 of the securing means 106. However, the locking means may extend according to other conceivable arrangements, for example only from a certain height of the means. securing (from the first end 1060) and / or to the second end 1061.

On note de plus que, selon les modes de réalisation illustrés par les figures 1, 4 et 5, le trou 110 peut être ménagé dans le barreau 104 de telle sorte que, une fois le barreau 104 emboîté complètement dans le barreau vertical 102, le trou 110 s'étende selon un axe non parallèle à l'axe du tube vertical 102 et orienté de telle sorte à préfigurer la position des moyens de solidarisation 106. Cette direction oblique des moyens de solidarisation assure que chacune des extrémités des moyens de solidarisation sont en appui, directement ou indirectement, contre la surface intérieure 1021 du barreau 102, y compris si le moyen de solidarisation présente une portion à son extrémité d'introduction 1021 d'un diamètre inférieur à celui d'une portion au voisinage de son extrémité opposée 1061.It is further noted that according to the embodiments illustrated by the figures 1 , 4 and 5 , the hole 110 can be formed in the bar 104 so that, once the bar 104 is fully engaged in the vertical bar 102, the hole 110 extends along an axis not parallel to the axis of the vertical tube 102 and oriented in such a way as to prefigure the position of the securing means 106. This oblique direction of the securing means ensures that each of the ends of the securing means bear, directly or indirectly, against the inner surface 1021 of the bar 102, including if the securing means has a portion at its insertion end 1021 of a diameter smaller than that of a portion in the vicinity of its opposite end 1061.

En référence à la figure 4, les moyens de blocage en position du moyen de solidarisation comprennent (en remplacement ou en complément du filetage ou des crans mentionnés précédemment) une extension radiale 1062 de l'axe du moyen de solidarisation 1060, cette extension pouvant prendre place à l'extrémité 1061 ou au voisinage de celle-ci.With reference to the figure 4 , the locking means in position of the securing means comprise (in replacement or in addition to the thread or notches mentioned above) a radial extension 1062 of the axis of the securing means 1060, this extension being able to take place at the end 1061 or in the vicinity thereof.

Cette extension radiale 1062 constitue un élément déformable destiné à être écrasé contre la surface intérieure 1021 du barreau vertical 102.This radial extension 1062 constitutes a deformable element intended to be crushed against the inner surface 1021 of the vertical bar 102.

Le diamètre extérieur de cette extension radiale 1062 est prévu de telle sorte que, lors de l'introduction du moyen de solidarisation 106 dans l'orifice 110, l'extension vienne en appui contre la paroi 1021. En poursuivant l'engagement du moyen de solidarisation 106 dans le trou 110, l'extension radiale se déforme (vers le bas lorsque le moyen de solidarisation est introduit par le bas du barreau 102, ou vers le haut lorsque le moyen de solidarisation est introduit par le haut du barreau 102). Cette déformation est engendrée du fait de l'orientation oblique du moyen de solidarisation 106 par rapport à la paroi 1021 du barreau vertical, cette orientation tendant à faire diminuer l'écartement entre l'extension radiale et la paroi 1021 au fur et à mesure de l'introduction du moyen de solidarisation dans le trou 110.The outer diameter of this radial extension 1062 is provided such that, during the introduction of the securing means 106 into the orifice 110, the extension bears against the wall 1021. By continuing the engagement of the fastening 106 in the hole 110, the radial extension is deformed (downwards when the securing means is introduced through the bottom of the bar 102, or upwards when the securing means is introduced through the top of the bar 102). This deformation is generated because of the oblique orientation of the securing means 106 relative to the wall 1021 of the vertical bar, this orientation tends to reduce the spacing between the radial extension and the wall 1021 as and when the introduction of the securing means in the hole 110.

Cette extension radiale est, selon le présent mode de réalisation, réalisée dans le même matériau que celui de l'axe du moyen de solidarisation , en l'occurrence dans un matériau métallique qui confère une rigidité suffisante à l'extension radiale 1062 une fois déformée et en appui contre la surface intérieure 1021, s'oppose au retrait du moyen de solidarisation à partir du trou 110.This radial extension is, according to the present embodiment, made of the same material as that of the axis of the securing means, in this case in a metallic material which gives sufficient rigidity to the radial extension 1062 once deformed and bearing against the inner surface 1021, opposes the removal of the securing means from the hole 110.

En référence à la figure 5, les moyens de blocage comprennent (en remplacement ou en complément du filetage ou des crans mentionnés précédemment) :

  • une rondelle 1063 ;
  • une tête 1062 formant butée et contre laquelle la rondelle 1063 prend appui.
With reference to the figure 5 , the locking means comprise (instead of or in addition to the threads or notches mentioned above):
  • a washer 1063;
  • a head 1062 forming a stop and against which the washer 1063 bears.

Préférentiellement, la rondelle 1063 est réalisée en un matériau élastiquement déformable.Preferably, the washer 1063 is made of an elastically deformable material.

Le diamètre extérieur de la rondelle 1063 est dimensionné de telle sorte que celle-ci vienne se déformer au contact de la surface intérieure 1021 du barreau vertical au fur et à mesure de l'introduction du moyen de solidarisation dans le trou 110. De façon similaire à ce qui a été indiqué ci-dessus, cette déformation est engendrée du fait de l'orientation oblique du moyen de solidarisation 106 par rapport à la surface intérieure 1021 qui tend à faire diminuer l'écartement entre l'extrémité 1061 et la surface intérieure 1021 au fur et à mesure de l'introduction du moyen de solidarisation dans le trou 110.The outer diameter of the washer 1063 is dimensioned such that it comes to deform in contact with the inner surface 1021 of the vertical bar as the insertion means into the hole 110. In a similar manner to what has been indicated above, this deformation is generated because of the oblique orientation of the securing means 106 relative to the inner surface 1021 which tends to reduce the spacing between the end 1061 and the inner surface 1021 as and when the fastening means is introduced into the hole 110.

Tel que cela apparaît sur la figure 5, une fois le moyen de solidarisation 106 mis en place, la déformation de la rondelle 1063 se traduit par l'apparition d'un bourrelet 1064 qui s'intercale entre la tête 1062 et la surface intérieure 1021 du barreau vertical.As it appears on the figure 5 once the securing means 106 is put in place, the deformation of the washer 1063 results in the appearance of a bead 1064 which is inserted between the head 1062 and the inner surface 1021 of the vertical bar.

La rondelle 1063 étant réalisée en un matériau élastiquement déformable, le bourrelet 1064 exerce une double fonction : une fonction selon laquelle le bourrelet 1064 agit (ou réagit) sur la tête 1062 de façon à s'opposer au retrait du moyen de solidarisation à partir du trou 110 et une fonction d'absorption des vibrations transmises par le barreau vertical.The washer 1063 being made of an elastically deformable material, the bead 1064 has a dual function: a function in which the bead 1064 acts (or reacts) on the head 1062 so as to oppose the removal of the securing means from the hole 110 and a vibration absorption function transmitted by the vertical bar.

On note que les moyens de blocage décrits en référence aux figures 4 et 5 peuvent être mis en oeuvre tant dans une disposition de l'axe selon laquelle celui-ci est introduit par l'extrémité inférieure du barreau vertical que dans une disposition selon laquelle l'axe est introduit par l'extrémité supérieure du barreau vertical.It is noted that the blocking means described with reference to figures 4 and 5 may be implemented both in a provision of the axis in which it is introduced by the lower end of the vertical bar in a provision according to which the axis is introduced by the upper end of the vertical bar.

Les figures 2 et 3 représentent un outil 200 pour assembler un ensemble 100 selon l'invention pour une grille barreaudée. Pour des raisons de mise en page, l'outil 200 est coupé en deux parties.The Figures 2 and 3 represent a tool 200 for assembling a set 100 according to the invention for a bar grid. For reasons of layout, the tool 200 is cut in two parts.

L'outil 200 comprend une extrémité d'insertion 202 et un corps extérieur 206.The tool 200 includes an insertion end 202 and an outer body 206.

L'extrémité d'insertion 202 est prévue pour pénétrer dans le barreau vertical 102 et, à cette fin, elle a un profil similaire au profil intérieur du barreau vertical 102. L'extrémité d'insertion 202 comprend une butée 204 qui vient en appui contre l'extrémité du barreau vertical 102 et la longueur de l'extrémité d'insertion 202 est telle que son extrémité libre avoisine le barreau horizontal ou la lisse 104. L'extrémité d'insertion 202 est percée d'un alésage de guidage 220 dont les dimensions permettent le passage du moyen de solidarisation et, en particulier, de son axe 106. L'alésage de guidage 220 est tel qu'il vient sensiblement s'aligner avec le trou débouchant 110. A cette fin, l'alésage de guidage 220 est disposé en biais et sa paroi 222 tend à disparaître en progressant vers l'extrémité libre de l'extrémité d'insertion 202.The insertion end 202 is provided to penetrate the vertical bar 102 and, for this purpose, it has a profile similar to the inner profile of the vertical bar 102. The insertion end 202 comprises a stop 204 which bears in abutment against the end of the vertical bar 102 and the length of the insertion end 202 is such that its free end is close to the horizontal bar or the bar 104. The insertion end 202 is pierced with a guide bore 220 whose dimensions allow passage of the securing means and, in particular, its axis 106. The guide bore 220 is such that it substantially aligns with the through hole 110. For this purpose, the bore of 220 is disposed at an angle and its wall 222 tends to disappear while progressing towards the free end of the insertion end 202.

Le corps extérieur 206 est disposé dans le prolongement de l'extrémité d'insertion 202 et il est percé d'un alésage de poussée 216 coaxial avec l'alésage de guidage 220. Le corps extérieur 206 est muni d'un piston 210.The outer body 206 is disposed in the extension of the insertion end 202 and is pierced with a thrust bore 216 coaxial with the guide bore 220. The outer body 206 is provided with a piston 210.

Le piston 210 comprend une poignée 212 prévue pour aider à la manipulation du piston 210, une tige 214 prévue pour s'insérer successivement dans l'alésage de poussée 216, puis dans l'alésage de guidage 220. L'extrémité 218 de la tige 214 est prévue pour pousser le moyen de solidarisation 106 au travers de l'alésage de poussée 216, de l'alésage de guidage 220, puis du trou débouchant 110.The piston 210 comprises a handle 212 provided to assist in the manipulation of the piston 210, a rod 214 provided to successively insert into the thrust bore 216, then into the guide bore 220. The end 218 of the rod 214 is provided to push the securing means 106 through the thrust bore 216, the guide bore 220, and the through hole 110.

Le fonctionnement de l'outil 200 est le suivant. L'extrémité d'insertion 202 est insérée et mise en butée dans le barreau vertical 102. Après retrait du piston 210, un moyen de solidarisation 106 est introduit dans l'alésage de poussée 216. Le piston 210 est introduit dans l'alésage de poussée 216 et il est déplacé de manière à ce que son extrémité 218 pousse le moyen de solidarisation 106. La poussée du piston 210 est poursuivie jusqu'à ce que le moyen de solidarisation traverse le trou débouchant 110 et soit disposé de part et d'autre du trou débouchant 110. L'extrémité d'insertion 202 peut être retirée et l'opération peut être recommencée sur un autre ensemble 100.The operation of the tool 200 is as follows. The insertion end 202 is inserted and abutted in the vertical bar 102. After removal of the piston 210, a securing means 106 is introduced into the thrust bore 216. The piston 210 is introduced into the bore of thrust 216 and it's moved so that its 218 end pushes the securing means 106. The thrust of the piston 210 is continued until the securing means passes through the through hole 110 and is disposed on either side of the through hole 110. The insertion end 202 may be removed and the operation can be restarted on another set 100.

Afin de guider au mieux le moyen de solidarisation 106, l'extrémité libre de l'extrémité d'insertion 202 est munie d'un moyen de guidage 224. Le moyen de guidage 224 est une rampe sur laquelle passe le moyen de solidarisation 106 et qui est mobile de manière à pouvoir être alignée avec le trou débouchant 110. Le moyen de guidage 224 est mobile en rotation autour d'un axe 226 sensiblement orthogonal à la direction de déplacement du moyen de solidarisation 106. Le réglage angulaire du moyen de guidage 224 est réalisé ici par une vis 228 qui appuie contre une partie de l'extrémité d'insertion 202.In order to best guide the securing means 106, the free end of the insertion end 202 is provided with a guiding means 224. The guiding means 224 is a ramp over which the securing means 106 and which is movable so as to be aligned with the through hole 110. The guide means 224 is rotatable about an axis 226 substantially orthogonal to the direction of movement of the securing means 106. The angular adjustment of the guide means 224 is made here by a screw 228 which bears against a part of the insertion end 202.
