Description

La présente invention concerne un dispositif de fixation d'une lisse sur un poteau, ainsi qu'une barrière comprenant de tels dispositifs de fixation. L'invention trouve application dans le domaine des clôtures.The present invention relates to a device for attaching a rail to a pole, and a barrier comprising such fasteners. The invention finds application in the field of fences.

On connaît une clôture comprenant des poteaux verticaux et des panneaux barreaudés. Chaque panneau barreaudé s'étend entre deux poteaux consécutifs et est constitué d'au moins une lisse inférieure et d'au moins une lisse supérieure entre lesquelles sont disposés des barreaux qui s'étendent entre l'une des lisses inférieures et l'une des lisses supérieures. La mise en place des panneaux sur les poteaux s'effectue par fixation des lisses sur les poteaux. La fixation de chaque lisse est réalisée par leur soudage ou leur vissage sur les poteaux. Le soudage présente le désavantage d'être long et dangereux pour le technicien réalisant la soudure, et inesthétique du fait de la présence de bourrelets au niveau des soudures. Le vissage présente le désavantage d'être visible et parfois facilement démontable pour une personne désirant traverser la clôture.A fence is known comprising vertical posts and barred panels. Each barred panel extends between two consecutive posts and consists of at least one lower rail and at least one upper rail between which are arranged bars which extend between one of the lower rail and one of upper smooth. The placement of the panels on the posts is done by fixing the rails on the poles. The fixing of each rail is achieved by their welding or screwing on the posts. Welding has the disadvantage of being long and dangerous for the technician performing the welding, and unsightly due to the presence of beads at the welds. The screwing has the disadvantage of being visible and sometimes easily removable for a person wishing to cross the fence.

La Fig. 1 représente un dispositif de fixation 100 d'une lisse 136 sur un poteau 134. Le poteau 134 s'étend verticalement et est constitué d'une coque creuse dont la paroi est traversée par une pluralité de trous 138. La lisse 136 s'étend horizontalement et prend, ici, la forme d'un tube cylindrique creux.The Fig. 1 is a fastening device 100 of a smooth 136 on a pole 134. The pole 134 extends vertically and consists of a hollow shell whose wall is traversed by a plurality of holes 138. The smooth 136 extends horizontally and here takes the form of a hollow cylindrical tube.

Dans un mode de réalisation particulier, représenté à la Fig. 8, une lisse supérieure 136a est solidaire d'une lisse inférieure 136b et entre ces deux lisses 136a et 136b s'étendent des barreaux 804. Cet ensemble des deux lisses 136a et 136b et des barreaux 804 forme une grille barreaudée qui se fixe entre deux poteaux consécutifs 134a et 134b. Les poteaux 134a et 134b et les grilles barreaudées forment, alors, une barrière 802 destinée à limiter un espace.In a particular embodiment, represented at Fig. 8 , an upper rail 136a is secured to a lower rail 136b and between these two rails 136a and 136b extend bars 804. This set of two smooth 136a and 136b and 804 bars form a bar grid that is fixed between two poles consecutive 134a and 134b. The posts 134a and 134b and the barred grids then form a barrier 802 for limiting a space.

Le dispositif de fixation 100 comprend:

  • des moyens de maintien de la lisse qui sont explicités ci-après;
  • un premier moyen de serrage adapté à pénétrer dans l'un des trous 138 et à venir en contact avec l'intérieur de la paroi du poteau 134; et
  • un deuxième moyen de serrage adapté à venir en contact avec l'extérieur de la paroi du poteau 134.
The fixing device 100 comprises:
  • means for maintaining the beam which are explained below;
  • a first clamping means adapted to penetrate one of the holes 138 and to come into contact with the inside of the wall of the pole 134; and
  • a second clamping means adapted to come into contact with the outside of the wall of the pole 134.

Dans le mode de réalisation de l'invention représenté à la Fig. 1, le premier moyen de serrage comprend une tête 104 solidaire d'un axe 114 sur lequel est disposée une goupille de blocage 118. La tête 104 est prévue pour s'insérer dans l'un des trous 138 et l'axe 114 s'étend dans la direction du deuxième moyen de serrage.In the embodiment of the invention shown in Fig. 1 , the first clamping means comprises a head 104 integral with an axis 114 on which a locking pin 118 is arranged. The head 104 is designed to fit into one of the holes 138 and the axis 114 extends in the direction of the second clamping means.

Dans le mode de réalisation de l'invention représenté à la Fig. 1, le deuxième moyen de serrage comprend, entre autres, un moyen élastique 102 et un corps 106 dans lequel est réalisé un cylindre de rotation 112 (voir Figs. 3 à 7). L'axe 114 du premier moyen de serrage est logé dans le cylindre de rotation 112 sur lequel est réalisée une rainure de blocage 126. L'ajustement entre le cylindre de rotation 112 et l'axe 114 est, de préférence, du type glissant juste.In the embodiment of the invention shown in Fig. 1 the second clamping means comprises, inter alia, an elastic means 102 and a body 106 in which a rotation cylinder 112 is formed (see FIG. Figs. 3 to 7 ). The axis 114 of the first clamping means is housed in the rotation cylinder 112 on which is made a locking groove 126. The adjustment between the rotation cylinder 112 and the axis 114 is preferably of the sliding type just .

Le moyen élastique 102 prend, ici, la forme d'un tronc de cône muni d'un alésage central pour permettre le passage de l'axe 114. Le moyen élastique 102 peut être par exemple un tronc de cône en caoutchouc ou un ressort de compression à très fort coefficient de raideur. Le moyen élastique 102 et donc le deuxième moyen de serrage sont compressibles, c'est-à-dire qu'il est possible de les comprimer et toute compression induit la création d'une force de poussée opposée. Avantageusement, cette force de poussée est utilisée pour contraindre la goupille de blocage 118 dans le fond de la rainure 126, comme cela est représenté à la Fig. 5. La base du tronc de cône 102 vient s'emmancher dans le corps 106. Pour faciliter l'alignement du moyen élastique 102 et du corps 106, celui-ci comprend un alésage dans lequel pénètre une excroissance cylindrique du moyen élastique 102. Comme cela est mieux vu sur la Fig. 7, le sommet 128 du tronc de cône 102 vient en contact avec l'extérieur de la paroi du poteau 134.The elastic means 102 here takes the form of a truncated cone provided with a central bore to allow the passage of the axis 114. The elastic means 102 may be for example a truncated cone rubber or a spring of compression with a very high coefficient of stiffness. The elastic means 102 and thus the second clamping means are compressible, that is to say that it is possible to compress them and any compression induces the creation of an opposing thrust force. Advantageously, this thrust force is used to constrain the locking pin 118 in the bottom of the groove 126, as shown in FIG. Fig. 5 . The base of the truncated cone 102 is engaged in the body 106. To facilitate the alignment of the elastic means 102 and the body 106, it comprises a bore into which a cylindrical protrusion of the elastic means 102 penetrates. better seen on the Fig. 7 the vertex 128 of the truncated cone 102 comes into contact with the outside of the wall of the pole 134.

L'extrémité de l'axe 114 qui ne porte pas la tête 104, est percée radialement d'un alésage de montage destiné à recevoir la goupille de blocage 118. L'extrémité de l'axe 114 qui porte la tête 104, est percée radialement d'un alésage de manoeuvre 116 (Fig. 3).The end of the axis 114 which does not bear the head 104, is pierced radially by a mounting bore for receiving the locking pin 118. The end of the shaft 114 which carries the head 104 is pierced. radially of a maneuvering bore 116 ( Fig. 3 ).

L'assemblage du dispositif de fixation 100 est le suivant: l'extrémité dépourvue de tête de l'axe 114 est insérée dans le moyen élastique 102, puis dans le corps 106. La goupille de blocage 118 est alors insérée dans l'alésage de l'axe 114, de manière à éviter tout démontage du dispositif de fixation 100.The assembly of the fixing device 100 is as follows: the head-free end of the shaft 114 is inserted into the elastic means 102, then into the body 106. The locking pin 118 is then inserted into the bore of the axis 114, so as to avoid any disassembly of the fixing device 100.

Selon un autre mode de réalisation de l'invention, la tête 104 n'est pas solidaire de l'axe 114 mais la goupille de blocage 118 est solidaire de l'axe 114. L'assemblage du dispositif de fixation 100 est alors le suivant: l'extrémité dépourvue de tête de l'axe 114 est insérée dans le corps 106, puis dans le moyen élastique 102. La goupille de blocage 118 est alors positionnée contre le cylindre de rotation 112 et la tête 104 est alors fixée à l'extrémité de l'axe 114, de manière à éviter tout démontage du dispositif de fixation 100.According to another embodiment of the invention, the head 104 is not integral with the axis 114 but the locking pin 118 is integral with the axis 114. The assembly of the fixing device 100 is then the following the headless end of the shaft 114 is inserted into the body 106, then into the elastic means 102. The locking pin 118 is then positioned against the rotation cylinder 112 and the head 104 is then fixed to the end of the axis 114, so as to avoid any disassembly of the fixing device 100.

La Fig. 2 représente le dispositif de fixation 100 lorsqu'il est assemblé. Le corps 106 et le moyen élastique 102 sont alors placés entre la tête 104 et la goupille 118.The Fig. 2 represents the fixing device 100 when assembled. The body 106 and the elastic means 102 are then placed between the head 104 and the pin 118.

La Fig. 3 représente une vue écorchée du dispositif de fixation 100 lorsqu'il est en position libre, c'est-à-dire lorsqu'il peut être monté librement dans l'un des trous 138 du poteau 134. Le premier moyen de serrage et le deuxième moyen de serrage n'exercent alors aucune force de serrage sur la paroi du poteau 134.The Fig. 3 represents a cut-away view of the fixing device 100 when it is in the free position, that is to say when it can be mounted freely in one of the holes 138 of the post 134. The first clamping means and the second clamping means then exert no clamping force on the wall of the pole 134.

Le corps 106 comprend de l'extérieur vers l'intérieur, un cylindre extérieur 130, un cylindre d'alignement 132 et le cylindre de rotation 112. Ces trois cylindres forment un ensemble monobloc.The body 106 comprises from outside to inside, an outer cylinder 130, an alignment cylinder 132 and the rotation cylinder 112. These three cylinders form a one-piece assembly.

Le cylindre extérieur 130 et le cylindre d'alignement 132 sont distants l'un de l'autre de manière à laisser libre un espace 110 formant un cylindre dont les dimensions sont choisies de manière à permettre l'insertion de la lisse 136 et qui constitue les moyens de maintien de la lisse 136. Les dimensions extérieures du cylindre d'alignement 132 sont légèrement inférieures aux dimensions intérieures de la lisse 136 et les dimensions intérieures du cylindre extérieur 130 sont légèrement supérieures aux dimensions extérieures de la lisse 136.The outer cylinder 130 and the alignment cylinder 132 are spaced apart from each other so as to leave free a space 110 forming a cylinder whose dimensions are chosen so as to allow the insertion of the beam 136 and which constitutes the means for holding the stringer 136. The external dimensions of the alignment cylinder 132 are slightly smaller than the internal dimensions of the stringer 136 and the internal dimensions of the outer cylinder 130 are slightly greater than the external dimensions of the stringer 136.

Selon un mode de réalisation particulier, la courbe directrice du cylindre extérieur 130, la courbe directrice du cylindre d'alignement 132, la courbe directrice de l'espace 110, la courbe directrice de la lisse 136 et la courbe directrice de l'excroissance du moyen élastique 102 sont des ellipses, ce qui évite, d'une part, la rotation de la lisse 136 dans l'espace 110, et, d'autre part, la rotation du moyen élastique 102 dans le corps 106.According to a particular embodiment, the guide curve of the outer cylinder 130, the guide curve of the alignment cylinder 132, the directional curve of the space 110, the guide curve of the rail 136 and the guide curve of the protrusion of the elastic means 102 are ellipses, which avoids, on the one hand, the rotation of the smooth 136 in the space 110, and, on the other hand, the rotation of the elastic means 102 in the body 106.

Le cylindre de rotation 112 s'étend au-delà du cylindre extérieur 130 et du cylindre d'alignement 132. La paroi du cylindre de rotation 112 est usinée de manière à réaliser une rampe 124 qui s'étend, dans le mode de réalisation décrit, sur environ un quart de tour. A l'une des extrémités de la rampe est disposée une première zone de blocage constituée de la rampe 124 et de la paroi non usinée du cylindre de rotation 112, et à l'autre extrémité de la rampe 124 est disposée une deuxième zone de blocage qui est, ici, constituée d'une rainure 126. La rampe 124 est montante de la première zone de blocage vers la deuxième zone de blocage 126. Le fond de la rainure 126 est placé en deçà du sommet de la rampe 124. En d'autres termes, la rampe 124 s'étend d'en deçà du fond de la rainure 126 à au-delà du fond de la rainure de blocage 126.The rotation cylinder 112 extends beyond the outer cylinder 130 and the alignment cylinder 132. The wall of the rotation cylinder 112 is machined so as to produce a ramp 124 which extends, in the embodiment described , about a quarter of a turn. At one end of the ramp is disposed a first blocking zone consisting of the ramp 124 and the unmachined wall of the rotation cylinder 112, and at the other end of the ramp 124 is disposed a second blocking zone. which is here constituted by a groove 126. The ramp 124 is rising from the first blocking zone to the second blocking zone 126. The bottom of the groove 126 is placed below the top of the ramp 124. In In other words, the ramp 124 extends from below the bottom of the groove 126 to beyond the bottom of the locking groove 126.

L'espace libre 110 est disposé à l'extérieur par rapport au cylindre de rotation 112 et à la rainure de blocage 126 pour que la goupille de blocage 118 et la rainure de blocage 126 soient cachées à l'intérieur de la lisse 136 et éviter ainsi le déverrouillage du dispositif de fixation 100 par action sur la goupille de blocage 118.The free space 110 is disposed outside with respect to the rotation cylinder 112 and the locking groove 126 so that the locking pin 118 and the locking groove 126 are hidden inside the rail 136 and avoid thus unlocking the fixing device 100 by action on the locking pin 118.

La distance entre la tête 104 et l'alésage de montage est telle que celui-ci doit être apparent au niveau de la première zone de blocage. C'est-à-dire que lorsque le moyen élastique 102 et le corps 106 sont traversés par l'axe 114, celui-ci est suffisamment long pour que la goupille de blocage 118 puisse être insérée dans l'alésage de montage sans que le moyen élastique 102 soit mis en compression. La longueur de l'axe 114 doit être également suffisante pour qu'un espace existe entre la tête 104 et l'extrémité 128 du moyen élastique 102 qui lui fait face. Cet espace permet l'insertion de la paroi du poteau 134 lors de la mise en place du dispositif de fixation 100 sur le poteau 134.The distance between the head 104 and the mounting bore is such that it must be apparent at the level of the first blocking zone. That is to say, when the elastic means 102 and the body 106 are traversed by the axis 114, the latter is long enough for the locking pin 118 to be inserted into the mounting bore without the elastic means 102 is put in compression. The length of the axis 114 must also be sufficient for a space exists between the head 104 and the end 128 of the resilient means 102 facing it. This space allows the insertion of the wall of the pole 134 during the establishment of the fixing device 100 on the pole 134.

Le cylindre extérieur 130 est percé d'un orifice 122 de forme générale oblongue dont l'axe suit sensiblement la rampe 124. De la même manière, le cylindre de rotation 112 est percé d'un orifice de guidage 120 qui a la même forme générale. Lorsque le dispositif de fixation 100 est assemblé, l'alésage de manoeuvre 116 est accessible à travers l'orifice de guidage 122 du cylindre extérieur 130 et l'orifice 120 du cylindre de rotation 112. Dans le mode de réalisation décrit, le cylindre d'alignement 132 ne s'étend pas jusqu'au dessus de l'alésage de manoeuvre 116 et il n'a donc pas besoin d'être percé d'un orifice permettant d'accéder à l'alésage de manoeuvre 116. L'alésage de manoeuvre 116 et la fenêtre d'accès constituée, d'une part, de l'orifice 120 du cylindre de rotation 112 et, d'autre part, de l'orifice de guidage 122 du cylindre extérieur 130 constituent des moyens de manoeuvre adaptés à faire passer le premier moyen de serrage et le deuxième moyen de serrage de la position libre à la position fixée et verrouillée. La fenêtre d'accès 120, 122 est ainsi réalisée dans le deuxième moyen de serrage et permet l'accès au trou de manoeuvre 116 depuis l'extérieur du deuxième moyen de serrage. L'alésage de manoeuvre 116 est dimensionné pour permettre l'insertion d'un outil, par exemple un tournevis.The outer cylinder 130 is pierced with an oblong generally oblong orifice 122 whose axis substantially follows the ramp 124. In the same way, the rotation cylinder 112 is pierced with a guide orifice 120 which has the same general shape . When the fixing device 100 is assembled, the operating bore 116 is accessible through the guide orifice 122 of the outer cylinder 130 and the orifice 120 of the cylinder in the embodiment described, the alignment cylinder 132 does not extend to the top of the operating bore 116 and therefore does not need to be pierced with a hole allowing to access the operating bore 116. The operating bore 116 and the access window constituted, on the one hand, by the orifice 120 of the rotation cylinder 112 and, on the other hand, by the Guide orifice 122 of the outer cylinder 130 constitute operating means adapted to move the first clamping means and the second clamping means from the free position to the fixed and locked position. The access window 120, 122 is thus formed in the second clamping means and allows access to the operating hole 116 from outside the second clamping means. The operating bore 116 is dimensioned to allow the insertion of a tool, for example a screwdriver.

La Fig. 4 représente une vue écorchée du dispositif de fixation 100 lorsqu'il est en position fixée mais non verrouillée. Cette position représente une étape intermédiaire entre la position de la Fig. 3 et la position de la Fig. 5 qui représente une vue écorchée du dispositif de fixation 100 lorsqu'il est en position fixée et verrouillée, c'est-à-dire qu'il ne peut plus être désolidarisé du poteau 134, le premier moyen de serrage et le deuxième moyen de serrage exerçant alors une force de serrage sur la paroi du poteau 134.The Fig. 4 represents a cutaway view of the fixing device 100 when in the fixed position but not locked. This position represents an intermediate step between the position of the Fig. 3 and the position of the Fig. 5 which represents a cut-away view of the fixing device 100 when in the fixed and locked position, that is to say that it can no longer be detached from the pole 134, the first clamping means and the second clamping means then exerting a clamping force on the wall of the pole 134.

La Fig. 4 représente le dispositif de fixation 100 après qu'un outil a été inséré dans l'alésage de manoeuvre 116 et que cet outil a été manoeuvré de manière à faire pivoter l'axe 114 à l'intérieur du cylindre de rotation 112. Guidé par la goupille de blocage 118 qui suit la rampe 124 pour venir se positionner en vis-à-vis de la rainure de blocage 126, l'outil suit les orifices de guidage 122, 120. Au cours de la rotation, la tête 104 et le moyen élastique 102 se rapprochent de manière à venir prendre en sandwich la paroi du poteau 134. Comme cela est expliqué ci-après, la rotation de l'axe 114 entraîne la mise en compression du moyen élastique 102 sous l'effet de la goupille de blocage 118 qui vient appuyer sur la rampe 124 repoussant ainsi le corps 106 contre la paroi du poteau 134 tout en faisant pivoter la tête 104. Ainsi, lors du passage de la position libre à la position fixée et verrouillée, la goupille de blocage 118 coopère avec la rampe 124. La mise en place du dispositif de fixation 100 est rapide car elle est réalisée par la rotation de la tête 104 sur environ un quart de tour et au plus un tour.The Fig. 4 represents the fixing device 100 after a tool has been inserted in the operating bore 116 and that this tool has been operated so as to rotate the shaft 114 inside the rotation cylinder 112. Guided by the locking pin 118 which follows the ramp 124 to be positioned vis-à-vis the locking groove 126, the tool follows the guide holes 122, 120. During the rotation, the head 104 and the means elastic 102 approach so as to sandwich the wall of the pole 134. As explained below, the rotation of the axis 114 causes the compression of the elastic means 102 under the effect of the locking pin 118 which presses on the ramp 124 thus pushing the body 106 against the wall of the pole 134 while pivoting the head 104. Thus, during the transition from the free position to the fixed and locked position, the locking pin 118 cooperates with the ramp 124. Placing e of the fixing device 100 is fast because it is achieved by the rotation of the head 104 about a quarter turn and at most one turn.

La Fig. 4 représente une position intermédiaire dans laquelle la goupille de blocage 118 est en vis-à-vis de la rainure de blocage 126 mais avant que le moyen élastique 102 n'ait repoussé le corps 106.The Fig. 4 represents an intermediate position in which the locking pin 118 is opposite the locking groove 126 but before the elastic means 102 has pushed the body 106 back.

La Fig. 5 représente la position finale lorsque le moyen élastique 102 a repoussé le corps 106 et donc positionné la goupille de blocage 118 dans la rainure de blocage 126. Lors du passage de la position intermédiaire de la Fig. 4 à la position finale de la Fig. 5, l'outil reste dans l'alésage de manoeuvre 116 et suit le déplacement de celui-ci.The Fig. 5 represents the final position when the elastic means 102 has pushed the body 106 and thus positioned the locking pin 118 in the locking groove 126. When passing from the intermediate position of the Fig. 4 at the final position of the Fig. 5 , the tool remains in the operating bore 116 and follows the movement thereof.

Dans la position finale de la Fig. 5, le moyen élastique 102 repousse librement le corps 106, ce qui a pour effet de venir contraindre la goupille de blocage 118 dans le fond de la rainure de blocage 126. Ainsi, le passage de la position libre à la position fixée et verrouillée s'accompagne de la mise en contrainte de la goupille de blocage 118 dans le fond de la rainure de blocage 126. La mise en contrainte de la goupille de blocage 118 dans le fond de la rainure de blocage 126 est réalisée par des moyens prévus à cet effet. Dans le mode de réalisation décrit sur les Figs., ces moyens comprennent, entre autres, le moyen élastique 102. La mise en place du dispositif de fixation 100 est alors simple et rapide.In the final position of the Fig. 5 , the elastic means 102 freely pushes the body 106, which has the effect of constraining the locking pin 118 in the bottom of the locking groove 126. Thus, the passage of the free position to the fixed and locked position s' accompanied by the setting of the locking pin 118 in the bottom of the locking groove 126. The constraining of the locking pin 118 in the bottom of the locking groove 126 is carried out by means provided for this purpose . In the embodiment described in Figs., These means comprise, inter alia, the elastic means 102. The establishment of the fixing device 100 is then simple and fast.

Le moyen élastique 102 doit rester suffisamment comprimé pour garantir la mise en tension du dispositif de fixation 100, c'est-à-dire que la goupille de blocage 118 doit être contrainte dans le fond de la rainure de blocage 126. La force de serrage de la paroi du poteau 134 entre le moyen élastique 102 et la tête 104 doit être suffisante pour éviter que le dispositif de fixation 100 ne soit mis en rotation autour de son axe et ainsi libère la tête 104 du trou 138. La distance de la tête 104 à la goupille de blocage 118 ainsi que la profondeur de la rainure de blocage 126 doivent rester suffisamment petites pour garantir que le moyen élastique reste en compression à la fin de la mise en place du dispositif de fixation 100.The elastic means 102 must remain sufficiently compressed to ensure the tensioning of the fastening device 100, that is to say that the locking pin 118 must be constrained in the bottom of the locking groove 126. The clamping force the wall of the pole 134 between the elastic means 102 and the head 104 must be sufficient to prevent the fixing device 100 from being rotated about its axis and thus releases the head 104 from the hole 138. The distance from the head 104 to the locking pin 118 and the depth of the locking groove 126 must remain small enough to ensure that the elastic means remains in compression at the end of the establishment of the fastening device 100.

La Fig. 6 représente le dispositif de fixation 100 lorsque la tête 104 est insérée dans l'un des trous 138 du poteau 134 et qu'il se trouve alors dans la position représentée à la Fig. 3.The Fig. 6 represents the fixing device 100 when the head 104 is inserted in one of the holes 138 of the pole 134 and that it is then in the position shown in FIG. Fig. 3 .

La Fig. 7 représente le dispositif de fixation 100 lorsque la paroi du poteau 134 est serrée entre la tête 104 et le moyen élastique 102. Le dispositif de fixation 100 est alors dans la position représentée à la Fig. 5.The Fig. 7 represents the fixing device 100 when the wall of the pole 134 is clamped between the head 104 and the elastic means 102. The fixing device 100 is then in the position shown in FIG. Fig. 5 .

Comme cela est mieux vu sur la Fig. 3, la tête 104 s'étend radialement par rapport à l'axe 114 et la face de la tête 104 qui se trouve en vis-à-vis de la paroi du poteau 134 présente une forme convexe, ce qui facilite le passage de la tête 104 derrière la paroi du poteau 134 et le serrage de la paroi du poteau 134 par la tête 104 lors de la rotation de la tête 104.As is best seen on the Fig. 3 , the head 104 extends radially relative to the axis 114 and the face of the head 104 which is opposite the wall of the pole 134 has a convex shape, which facilitates the passage of the head 104 behind the wall of the pole 134 and the tightening of the wall of the pole 134 by the head 104 during the rotation of the head 104.

Le passage de la position libre (Fig. 6) à la position fixée et verrouillée (Fig. 7) s'effectue par rotation de la tête 104 à l'intérieur du poteau 134 de manière à ce que la paroi du poteau 134 se place entre la tête 104 et le moyen élastique 102. Lors de la rotation de l'axe 114, la tête 104 vient se plaquer à l'intérieur du poteau 134 et le corps 106 est poussé par la goupille de blocage 118 contre la paroi extérieure du poteau 134. Le déplacement du corps 106 entraîne le déplacement du moyen élastique 102 qui vient appuyer contre la paroi extérieure du poteau 134. Le moyen élastique 102 est ainsi comprimé et se déforme pour venir épouser la forme de la paroi extérieure du poteau 134, ce qui augmente la force de friction entre le poteau 134 et le moyen élastique 102 et évite ainsi tout démontage du dispositif de fixation 100 par glissement sur la paroi du poteau 134. Lorsque la goupille de blocage 118 se loge dans la rainure de blocage 126, la déformation du moyen élastique 102 se réduit mais elle reste suffisante pour que le moyen élastique 102 exerce une force de serrage sur la paroi du poteau 134 en coopération avec la tête 104.The passage of the free position ( Fig. 6 ) at the fixed and locked position ( Fig. 7 ) is made by rotation of the head 104 inside the pole 134 so that the wall of the pole 134 is placed between the head 104 and the elastic means 102. During the rotation of the axis 114, the head 104 is pressed inside the pole 134 and the body 106 is pushed by the locking pin 118 against the outer wall of the pole 134. The displacement of the body 106 causes the displacement of the elastic means 102 which presses against the wall The elastic means 102 is thus compressed and deformed to fit the shape of the outer wall of the pole 134, which increases the frictional force between the pole 134 and the elastic means 102 and thus avoids any disassembly of the pole. fixing device 100 by sliding on the wall of the pole 134. When the locking pin 118 is housed in the locking groove 126, the deformation of the elastic means 102 is reduced but it remains sufficient for the means 102 exerts a clamping force on the wall of the pole 134 in cooperation with the head 104.

La Fig. 8 représente la barrière 802 comportant une grille barreaudée et dont la réalisation peut, par exemple, consister en:

  • la pose d'un premier poteau 134a,
  • la fixation et le verrouillage de dispositifs de fixation d'un premier type 100a sur le premier poteau 134a,
  • l'insertion de la première extrémité de chaque lisse 136a, 136b dans l'espace 110 du dispositif de fixation du premier type 100a correspondant,
  • la mise en place de dispositif de fixation d'un deuxième type 100b au niveau de la deuxième extrémité de chaque lisse 136a, 136b,
  • la fixation et le verrouillage des dispositifs de fixation du deuxième type 100b sur un deuxième poteau 134b;
  • la mise en place du deuxième poteau 134b à une distance telle qu'elle permet l'insertion de la deuxième extrémité de chaque lisse 136a, 136b dans l'espace 110 du dispositif de fixation du deuxième type 100b correspondant.
The Fig. 8 represents the barrier 802 comprising a barred grid and the realization of which may, for example, consist of:
  • the laying of a first pole 134a,
  • fixing and locking fasteners of a first type 100a on the first pole 134a,
  • inserting the first end of each stringer 136a, 136b into the space 110 of the corresponding first type fixing device 100a,
  • placing a securing device of a second type 100b at the second end of each stringer 136a, 136b,
  • securing and locking securing devices of the second type 100b on a second pole 134b;
  • the establishment of the second pole 134b at a distance such that it allows the insertion of the second end of each smooth 136a, 136b in the space 110 of the fixing device of the corresponding second type 100b.

Selon un autre mode de réalisation, chaque extrémité de chaque lisse 136a, 136b est préalablement rendue solidaire d'un dispositif de fixation 100a, 100b. La réalisation de la barrière 802 peut alors consister en:

  • la pose d'un premier poteau 134a,
  • la fixation et le verrouillage des dispositifs de fixation d'un premier type 100a sur le premier poteau 134a,
  • la fixation et le verrouillage des dispositifs de fixation du deuxième type 100b sur un deuxième poteau 134b;
  • la pose du deuxième poteau 134b.
According to another embodiment, each end of each smooth 136a, 136b is previously secured to a fastener 100a, 100b. The construction of the barrier 802 can then consist of:
  • the laying of a first pole 134a,
  • fixing and locking fasteners of a first type 100a on the first pole 134a,
  • securing and locking securing devices of the second type 100b on a second pole 134b;
  • the laying of the second pole 134b.

Lorsque la barrière 802 comprend uniquement un ensemble de poteaux 134a et 134b et une lisse 136b, le procédé de réalisation précédent peut être utilisé en l'adaptant du fait qu'il n'y a qu'un dispositif de fixation du premier type 100a et qu'un dispositif de fixation du deuxième type 100b.When the barrier 802 comprises only a set of posts 134a and 134b and a stringer 136b, the preceding embodiment can be used by adapting it because there is only one fastener of the first type 100a and a fixing device of the second type 100b.

Pour éviter tout déplacement des lisses 136 par rapport aux dispositifs de fixation 100, la fixation des lisses 136 et des dispositifs de fixation 100 peut être réalisée par exemple par emmanchement sans jeu, par rivetage ou par tout autre procédé de fixation supprimant tout jeu entre les lisses 136 et les dispositifs de fixation 100.In order to prevent any movement of the heddles 136 with respect to the fixing devices 100, the hinges 136 and the fixing devices 100 may be fixed, for example by fitting without play, by riveting or by any other fixing method, eliminating any clearance between the hinges. smooth 136 and fasteners 100.

Bien entendu, la présente invention n'est pas limitée aux exemples et modes de réalisation décrits et représentés, mais elle est susceptible de nombreuses variantes accessibles à l'homme de l'art.Of course, the present invention is not limited to the examples and embodiments described and shown, but it is capable of numerous variants accessible to those skilled in the art.

Par exemple, dans la description, le cylindre extérieur 130, le cylindre d'alignement 132, l'espace 110, la lisse 136 et l'excroissance du moyen élastique 102 sont plus particulièrement décrits comme des cylindres de révolution ou des cylindres elliptiques, mais ils pourraient prendre, par exemple, la forme de prisme.For example, in the description, the outer cylinder 130, the alignment cylinder 132, the space 110, the beam 136 and the protrusion of the elastic means 102 are more particularly described as cylinders of revolution or elliptical cylinders, but they could take, for example, the shape of a prism.

L'invention a été plus particulièrement décrite dans le cas où la goupille de blocage est solidaire du premier moyen de serrage et la rainure de blocage réalisée dans le deuxième moyen de serrage, mais il est possible d'intervertir les positions respectives de la goupille de blocage et de la rainure de blocage.The invention has been more particularly described in the case where the locking pin is secured to the first clamping means and the locking groove formed in the second clamping means, but it is possible to switch the respective positions of the pin of blocking and locking groove.

Dans la description ci-dessus, seul le deuxième moyen de serrage a été choisi comme étant compressible, mais il est possible de choisir que le premier moyen de serrage est compressible ou que les deux le sont. Les moyens prévus pour mettre en contrainte la goupille de blocage dans le fond de la rainure peuvent alors être constitués du premier moyen de serrage et/ou du deuxième moyen de serrage.In the above description, only the second clamping means has been selected as being compressible, but it is possible to choose whether the first clamping means is compressible or both are compressible. The means provided for biasing the locking pin in the bottom of the groove may then consist of the first clamping means and / or the second clamping means.

Dans la description ci-dessus, une seule goupille de blocage a été prévue, mais il est possible d'en prévoir au moins deux réparties sur le pourtour du premier moyen de serrage. Il est alors préférable de prévoir au moins autant de rampes qu'il y a de goupilles de blocage.In the description above, only one locking pin has been provided, but it is possible to provide at least two distributed around the periphery of the first clamping means. It is then preferable to provide at least as many ramps as there are locking pins.

Dans la description ci-dessus, l'orientation de la rampe n'est pas précisée car la rampe peut être orientée dans le sens trigonométrique direct ou dans le sens trigonométrique indirect. Dans le cas où il y a plusieurs rampes, il est possible de prévoir que certaines soient orientées dans le sens trigonométrique direct et que d'autres soient orientées dans le sens trigonométrique indirect.In the description above, the orientation of the ramp is not specified because the ramp can be oriented in the direct trigonometric direction or in the indirect trigonometric direction. In the case where there are several ramps, it is possible to predict that some are oriented in the direct trigonometric direction and that others are oriented in the indirect trigonometric direction.
