Abstract

The post (11) has a C-shaped straight sectioned profile (2) extending longitudinally, parallely and exteriorly to a round sectioned closed tubular profile (1), and including two wings (4) with free ends (3) welded by points (5) on a wall (12) of the tubular profile. The C-shaped profile has a core (6) that is provided with pawls (7) for anchoring and maintaining wires or wire meshes of a fence. The pawls are projected from one end to another end of the C-shaped profile. The pawls are formed by partial cutting and deformation of a sheet metal forming the C-shaped profile.

Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

La présente invention a trait à un perfectionnement apporté aux poteaux de clôture métalliques permettant l'accrochage et le maintien de fils ou de grillages de clôture, les poteaux concernés par ledit perfectionnement étant du type de ceux constitués de profilés tubulaires fermés, à section ronde, carrée ou rectangulaire.The present invention relates to an improvement made to the metal fence posts for attaching and holding fence wires or grids, the posts concerned by said improvement being of the type of those consisting of closed tubular sections, with round section, square or rectangular.

ARRIÈRE PLAN TECHNOLOGIQUE DE L'INVENTIONBACKGROUND OF THE INVENTION

Pour clôturer des emprises ferroviaires, routières ou autoroutières, aéroportuaires ou portuaires, et de même pour délimiter les entourages de propriétés privées, d'espaces verts, de terrains d'agriculture, de réserves de chasse, de parkings ou encore de golfs par exemple, il est connu de longue date d'utiliser des poteaux de clôture métalliques sur lesquels sont accrochés et maintenus des fils ou des grillages de clôture.To enclose railway, road or motorway, airport or port rights-of-way, and also to delimit the boundaries of private properties, green spaces, agricultural fields, hunting reserves, car parks or even golf courses, for example, it has long been known to use metal fence posts on which are hung and held wire or fence wire.

De tels poteaux de clôture métalliques sont en général des profilés dont les sections peuvent être variées. En effet, ces profilés métalliques peuvent être :

  1. a) soit ouverts, et alors leurs sections sont le plus souvent en forme de C ;
  2. b) soit tubulaires, donc fermés, et alors leurs sections sont rondes, carrées ou rectangulaires.
Such metal fence posts are generally profiles whose sections can be varied. Indeed, these metal profiles can be:
  1. a) open, and then their sections are most often C-shaped;
  2. b) tubular, thus closed, and then their sections are round, square or rectangular.

Les poteaux ouverts, notamment les poteaux profilés à section droite en C, sont généralement associés à une embase dont la section droite est complémentaire de celle du poteau, ladite embase étant alors destinée à être au moins partiellement enterrée et le poteau, destiné à surmonter ladite embase, étant soit inséré en partie supérieure de celle-ci, soit, à l'inverse, emmanché autour de la partie supérieure de celle-ci.The open columns, in particular the profiled posts with a straight section in C, are generally associated with a base whose cross-section is complementary to that of the post, said base then being intended to be at least partially buried and the post, intended to overcome said base, being inserted in the upper part of it, or, conversely, fitted around the upper part thereof.

L'accrochage et le maintien des fils ou des grillages de clôture sur de tels poteaux profilés à section droite en C est obtenu par la prévision, sur au moins l'une des parois de chaque profilé, en général la paroi dite « âme centrale » opposée à la paroi du profilé en C présentant une ouverture longitudinale, d'une succession de linguets disposés à intervalles réguliers, en saillie par rapport à ladite paroi, et dont l'extrémité libre est le plus couramment tournée vers le haut afin d'assurer l'accrochage du fil, ou de l'un des fils du grillage, avant d'être rabattue sur l'âme centrale, du moins pour ce qui est des linguets alors utilisés.The attachment and maintenance of the son or fencing grids on such profiled posts C section is obtained by predicting, on at least one of the walls of each profile, in general the wall called "central core" opposite to the wall of the C-section having a longitudinal opening, a succession of latches arranged at regular intervals, projecting from said wall, and whose free end is most commonly facing upwards to ensure the hooking of the wire, or one of the wires of the mesh, before being folded down on the central core, at least for the pawls then used.

Les linguets sont réalisés sur la ligne de profilage de la tôle constitutive des futurs profilés en C, au cours de l'opération de profilage, à l'aide d'outils de poinçonnage, et cela sans qu'il soit nécessaire de ralentir la cadence de la ligne de profilage, laquelle est de l'ordre de 20 mètres par minute.The latches are made on the profiling line of the sheet forming the future C-profiles, during the profiling operation, using punching tools, and this without the need to slow down the pace of the profiling line, which is of the order of 20 meters per minute.

Les poteaux tubulaires fermés sont pour leur part associés à des crochets ou à des agrafes spécifiquement adaptés à la réception des fils ou des grillages de la clôture à installer.The closed tubular poles are in turn associated with hooks or staples specifically adapted to receiving the son or fences of the fence to be installed.

Il est en effet déraisonnable d'un point de vue économique d'envisager le poinçonnage de la tôle constitutive des futurs poteaux tubulaires fermés en vue de la réalisation de linguets, car la cadence des lignes de profilage des produits tubulaires est de l'ordre de 120 mètres par minute, vitesse à laquelle il est impossible d'assurer la réalisation de linguets qui soient parfaitement formés et qui soient disposés à des intervalles parfaitement définis, imposés par la construction.It is indeed unreasonable from an economic point of view to consider the punching of the sheet constitutive future closed tubular poles for the realization of pawls, because the rate of profiling lines tubular products is of the order of 120 meters per minute, speed at which it is impossible to ensure the realization of pawls that are perfectly formed and are arranged at intervals perfectly defined, imposed by the construction.

Or, ralentir dans le rapport de 1 à 6 la cadence d'une ligne de profilage de produits tubulaires fermés s'avérerait extrêmement coûteux pour l'entreprise de profilage, et ce d'autant plus que la production de profilés tubulaires fermés exigeant la prévision de linguets est généralement effectuée par petites séries, et assurément selon des quantités qui sont infimes comparées à celles voulues pour la production de profilés tubulaires fermés qui n'exigent aucun poinçonnage.However, slowing in the ratio of 1 to 6 the rate of a profiling line of closed tubular products would be extremely expensive for the profiling company, especially since the production of closed tubular sections requiring the forecast of pawls is usually done in small series, and certainly in quantities that are compared to those required for the production of closed tubular sections that require no punching.

Cela étant, et mis à part le fait que certaines entreprises sont des inconditionnelles des poteaux de clôture ouverts ou, selon, fermés, il faut convenir que les uns et les autres ont des avantages.That being the case, and apart from the fact that some companies are unconditional open fence poles or, according to closed, it must be agreed that both have advantages.

Ainsi, quant à leur pose, les poteaux ouverts peuvent être associés à des embases, ainsi qu'il a été spécifié en préliminaire, embases qui sont alors battues dans le sol du terrain à clôturer, aux endroits voulus, et qui reçoivent ensuite chacune leur poteau complémentaire.Thus, as regards their installation, the open posts can be associated with bases, as it was specified in preliminary, bases which are then beaten in the soil of the ground to be fenced, in the desired places, and which then receive each their complementary post.

A l'inverse, les poteaux fermés ne peuvent pas être associés à des embases. Pour leur installation, il convient donc de creuser des trous dans le sol, aux endroits voulus, de placer un poteau tubulaire au centre de chaque trou et ensuite de remplir ce dernier d'un massif de béton qui assurera le scellement dudit poteau.Conversely, closed poles can not be associated with bases. For their installation, it is therefore necessary to dig holes in the ground, at the desired locations, to place a tubular pole in the center of each hole and then fill the latter with a concrete block that will seal the post.

La pose d'un poteau fermé est donc assurément plus longue, plus complexe et plus coûteuse que celle d'un poteau ouvert.The installation of a closed post is certainly longer, more complex and more expensive than that of an open post.

Quant à leur efficacité, les poteaux ouverts sont de très loin préférables aux poteaux fermés, du fait de l'utilisation de linguets qui à la fois sont, par construction, solidaires de leur poteau et qui emprisonnent définitivement les fils auxquels ils sont associés si, au moment de la pose de la clôture, ils sont chacun convenablement rabattus par l'installateur sur le fil à emprisonner.As for their effectiveness, open poles are far better than closed poles, because of the use of latches which are both by construction, integral with their post and which permanently imprison the son to which they are associated if, at the time of laying the fence, they are each suitably folded by the installer on the wire to imprison.

A l'inverse, les crochets ou les agrafes utilisés avec les poteaux fermés sont beaucoup moins résistants que les linguets et, à la suite de fortes poussées dues au vent ou aux plantations situées à proximité de la clôture, voire aux animaux sauvages qui veulent franchir ladite clôture, il est fréquent que les crochets/agrafes, et avec eux le grillage qui leur est attaché, se désolidarisent de ces poteaux, avec les graves conséquences que cela peut avoir.Conversely, hooks or staples used with closed poles are much less resistant than pawls and, following strong outbreaks due to wind or plantations near the fence, or even wild animals that want to cross said fence, it is common that the hooks / staples, and with them the mesh attached to them, are disassociated from these posts, with the serious consequences that it can have.

Quant aux caractéristiques mécaniques, les poteaux fermés s'avèrent en revanche meilleurs que les poteaux ouverts : à quantité de matière égale, c'est-à-dire à poids au mètre égal, ils présentent des moments d'inertie et des caractéristiques de résistance à la flexion et à la torsion beaucoup plus élevés.As for the mechanical characteristics, closed poles turn out to be better than open poles: equal amount of material, that is to say equal weight per meter, they have moments of inertia and characteristics of resistance to bending and torsion much higher.

Autrement dit, lorsque des exigences de résistance mécanique particulièrement élevées s'imposent, notamment à propos de l'inertie et à son corollaire, la résistance aux déformations, l'installateur s'oriente davantage vers l'utilisation de poteaux fermés, de préférence aux poteaux ouverts dont il faudrait pour cela augmenter l'épaisseur, solution qui conduirait à augmenter le prix de fabrication, voire, dans certains cas, conduirait à une impossibilité de fabrication puisque les outillages traditionnels ne permettraient alors pas leur profilage.In other words, when particularly high strength requirements are required, particularly with regard to inertia and its corollary, resistance to deformation, the installer is more oriented towards the use of closed poles, preferably open poles which would be necessary to increase the thickness, which would lead to increase the manufacturing price or, in some cases, lead to an impossibility of manufacture since the traditional tools would not then allow their profiling.

Quand bien même l'emploi de poteaux tubulaires nécessite la prévision de scellement par des massifs de béton, leur emploi est alors souhaitable, si ce n'est obligatoire, lorsque l'utilisateur exige que de tels poteaux présentent des caractéristiques mécaniques élevées.Even if the use of tubular posts requires the provision of sealing by concrete blocks, their use is then desirable, if not mandatory, when the user requires that such posts have high mechanical characteristics.

Il existe donc le besoin évident de proposer dans ces cas particuliers un poteau tubulaire idéal, c'est-à-dire d'une efficacité certaine quant au maintien du grillage de clôture, à savoir un poteau tubulaire doté de linguets dont la fabrication soit aisée et d'un coût raisonnable.There is therefore the obvious need to propose in these particular cases an ideal tubular post, that is to say, a certain efficiency in maintaining the fence fence, namely a tubular pole with latches whose manufacture is easy and a reasonable cost.

La présente invention propose un poteau tubulaire qui répond à ces divers critères.The present invention provides a tubular pole that meets these various criteria.

DESCRIPTION GÉNÉRALE DE L'INVENTIONGENERAL DESCRIPTION OF THE INVENTION

La présente invention a ainsi pour objet un poteau de clôture métallique, permettant l'accrochage et le maintien de fils ou de grillages de clôture, ledit poteau, qui est du type constitué d'un profilé tubulaire fermé, à section ronde, carrée ou rectangulaire, se caractérisant par le fait qu'il comprend en outre un profilé à section droite en C qui s'étend longitudinalement, parallèlement et extérieurement au profilé tubulaire fermé, les extrémités libres des deux ailes du profilé en C étant soudées sur la paroi du profilé tubulaire fermé et l'âme du profilé en C étant dotée de linguets adaptés pour l'accrochage et le maintien des fils ou des grillages de la clôture et disposés en saillie de place en place d'une extrémité à l'autre dudit profilé en C, lesdits linguets étant formés par découpage partiel et déformation de la tôle constitutive dudit profilé en C.The present invention thus relates to a metal fence post, allowing the attachment and maintenance of son or fencing grids, said post, which is of the type consisting of a closed tubular section, round, square or rectangular section , characterized in that it further comprises a C-section section that extends longitudinally, parallel and externally to the closed tubular section, the free ends of the two wings of the C-profile being welded to the wall of the closed tubular section and the core of the C-profile being provided with latches adapted for hooking and holding the wires or fences of the fence and arranged projecting from place to place one end to the other of said C-section, said latches being formed by partial cutting and deformation of the constituent plate of said profile C.

De préférence, les linguets sont disposés le long de l'axe longitudinal de symétrie du profilé en C, ou à proximité immédiate de cet axe longitudinal, et, de préférence encore, lesdits linguets sont disposés selon un intervalle régulier, d'une extrémité à l'autre du profilé en C.Preferably, the latches are arranged along the longitudinal axis of symmetry of the C-section, or in the immediate vicinity of this longitudinal axis, and, preferably, said latches are arranged at a regular interval, from one end to the other of the C profile.

Selon une forme de réalisation préférentielle, la face intérieure de l'âme du profilé en C est en contact avec la paroi du profilé tubulaire fermé, ou à proximité immédiate de cette paroi.According to a preferred embodiment, the inner face of the core of the C-profile is in contact with the wall of the closed tubular section, or in the immediate vicinity of this wall.

Très avantageusement, l'âme du profilé en C comporte un bossage dont la concavité est tournée dans la direction opposée à celle des deux ailes dudit profilé en C et c'est alors la face intérieure de ce bossage qui est en contact avec la paroi du profilé tubulaire fermé, ou à proximité immédiate de cette paroi.Very advantageously, the soul of the C-shaped profile comprises a boss whose concavity is turned in the direction opposite to that of the two wings of said C-section and it is then the inner face of this boss which is in contact with the wall of the closed tubular section, or in the immediate vicinity of this wall.

De préférence également, le profilé en C ne s'étend que sur une partie de la longueur du profilé tubulaire fermé et, dans ce cas, il ne recouvre pas la base dudit profilé tubulaire.Also preferably, the C-section extends only over a portion of the length of the closed tubular section and, in this case, it does not cover the base of said tubular section.

Dans le cas particulier où le profilé tubulaire fermé est de section ronde, le poteau de clôture selon l'invention est avantageusement tel que, en projection transversale, le profilé en C recouvre entre le quart et la moitié de la paroi extérieure du profilé tubulaire fermé et, de préférence encore, ledit profilé en C recouvre entre 28% et 40% de la paroi extérieure dudit profilé tubulaire fermé.In the particular case where the closed tubular section is of round section, the fence post according to the invention is advantageously such that, in transverse projection, the C-profile covers between the quarter and half of the outer wall of the closed tubular section and, more preferably, said C-profile covers between 28% and 40% of the outer wall of said closed tubular section.

Selon encore une autre forme de réalisation préférentielle, chacune des deux ailes du profilé en C est prolongée à son extrémité libre d'un retour qui épouse la forme de la paroi du profilé tubulaire fermé sur lequel il s'applique.According to yet another preferred embodiment, each of the two wings of the C-profile is extended at its free end with a return that matches the shape of the wall of the closed tubular section on which it is applied.

DESCRIPTION D'UN MODE DE RÉALISATION PRÉFÉRÉ DE L'INVENTIONDESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION

Le poteau de clôture métallique selon l'invention est donc constitué d'un profilé de base ou profilé principal, qui est tubulaire et fermé, et d'un profilé auxiliaire qui a une section en C.The metal fence post according to the invention therefore consists of a main section or main profile, which is tubular and closed, and an auxiliary section which has a section C.

Sur les dessins annexés, et dans la description qui va suivre, le profilé tubulaire a été choisi comme étant de section ronde.In the accompanying drawings, and in the following description, the tubular section was chosen to be of round section.

On comprend toutefois que l'invention s'applique également, sans modification autre que celle de leur section transversale, aux poteaux dans lesquels le profilé tubulaire principal est de section carrée ou rectangulaire.However, it is understood that the invention also applies, without modification other than that of their cross section, poles in which the main tubular section is square or rectangular section.

Le poteau 11 selon l'invention est notamment illustré en coupe transversale à la Figure 1 et en perspective à la Figure 2.The post 11 according to the invention is particularly illustrated in cross-section at the Figure 1 and in perspective at the Figure 2 .

Il se compose donc d'un profilé tubulaire fermé 1 et d'un profilé 2 à section droite en C qui s'étend longitudinalement, parallèlement et extérieurement au profilé tubulaire 1, les extrémités libres 3 des deux ailes 4 du profilé en C étant soudées en 5 sur la paroi du profilé tubulaire 1.It therefore consists of a closed tubular section 1 and a C-section section 2 that extends longitudinally, parallel and outwardly to the tubular section 1. free ends 3 of the two wings 4 of the C-profile being welded at 5 to the wall of the tubular section 1.

L'âme 6 du profilé 2 en C est dotée de linguets 7 adaptés pour l'accrochage et le maintien des fils ou des grillages de la clôture.The core 6 of the profile 2 in C is provided with latches 7 adapted for the attachment and maintenance of the son or fences of the fence.

Pour cela, et selon un procédé qui est parfaitement connu et maîtrisé, la tôle constitutive du futur profilé 2 en C est partiellement découpée et déformée à l'aide d'un poinçon, préalablement à l'opération de profilage du profilé 2 en C, ou au cours de cette opération de profilage, de telle sorte que les linguets 7 fassent saillie relativement à l'âme 6 dans la direction opposée à celle des deux ailes 4.For this, and according to a method that is perfectly known and controlled, the constituent sheet of the future profile 2 C is partially cut and deformed using a punch, prior to the profiling operation of the profile 2 in C, or during this profiling operation, so that the latches 7 protrude relative to the core 6 in the opposite direction to that of the two wings 4.

Avantageusement, les linguets sont prévus de place en place, de préférence selon un pas constant, c'est-à-dire selon un intervalle régulier, d'une extrémité 8 à l'autre 9 du profilé 2 en C.Advantageously, the latches are provided from place to place, preferably in a constant pitch, that is to say at a regular interval, from one end 8 to the other 9 of the section 2 C.

Les linguets 7 sont de préférence disposés le long de l'axe longitudinal de symétrie 10 du profilé 2 en C, axe 10 qui est aussi l'axe longitudinal de symétrie du poteau 11, ou à proximité immédiate de cet axe 10.The latches 7 are preferably arranged along the longitudinal axis of symmetry 10 of the profile 2 in C, axis 10 which is also the longitudinal axis of symmetry of the post 11, or in the immediate vicinity of this axis 10.

La face intérieure de l'âme 6 du profilé en C est de préférence en contact avec la paroi 12 du profilé tubulaire fermé 1, ou à proximité immédiate de cette paroi 12.The inner face of the core 6 of the C-profile is preferably in contact with the wall 12 of the closed tubular section 1, or in the immediate vicinity of this wall 12.

Dans une variante de construction, l'âme 6 du profilé 2 en C peut comporter un bossage 13 dont la concavité est tournée dans la direction opposée à celle des deux ailes 4 dudit profilé 2 en C, et c'est alors la face intérieure 14 de ce bossage qui est en contact avec la paroi 12 du profilé tubulaire fermé 1, ou à proximité immédiate de la paroi.In a variant of construction, the core 6 of the profile 2 in C may comprise a boss 13 whose concavity is turned in the opposite direction to that of the two wings 4 of said section 2 C, and it is then the inner face 14 this boss which is in contact with the wall 12 of the closed tubular section 1, or in the immediate vicinity of the wall.

Ainsi qu'il est visible sur les Figures 5 et 6, le profilé 2 en C est soudé de place en place par points 5 sur le profilé tubulaire fermé 1, lequel peut être un simple tube ordinaire du type de ceux que de multiples entreprises commercialisent.As it is visible on Figures 5 and 6 , the C-section 2 is welded from place to place by points 5 on the closed tubular section 1, which can be a simple ordinary tube of the type that multiple companies market.

Toutefois, le cas échéant, chaque soudure 5 du profilé 2 en C sur le profilé tubulaire fermé 1 peut être continue, d'une extrémité à l'autre du profilé 2 en C.However, where appropriate, each weld 5 of the C-section 2 on the closed tubular section 1 may be continuous, from one end to the other of the C-section 2.

Il a été exposé en préliminaire que les poteaux tubulaires sont scellés dans des massifs de béton.It has been exposed in preliminary that the tubular posts are sealed in concrete beds.

Il n'y a donc pas nécessité à prévoir que le profilé 2 en C s'étende d'une extrémité à l'autre du profilé tubulaire fermé 1 et, notamment, qu'il recouvre ledit profilé tubulaire à la base de celui-ci, et plus exactement pour sa partie qui est prise dans le massif de béton.There is therefore no need to provide that the profile 2 in C extends from one end to the other of the closed tubular section 1 and, in particular, that it covers said tubular section at the base thereof , and more exactly for its part which is taken in the solid mass of concrete.

Il a été représenté à titre d'exemple aux Figures 2, 3, 5 et 6 un poteau conforme à l'invention dans lequel le profilé 2 en C ne recouvre pas la partie 15 du profilé tubulaire fermé 1 qui formera la base enfouie de ce profilé.He was represented as an example to Figures 2 , 3, 5 and 6 a pole according to the invention wherein the C-section 2 does not cover the portion 15 of the closed tubular section 1 which will form the buried base of this section.

Selon encore une autre variante de construction, chacune des deux ailes 4 du profilé 2 en C peut être prolongée à son extrémité libre d'un retour 16 représenté en pointillés à la Figure 1, retour qui est orienté vers l'extérieur et qui épouse la forme de la paroi 12 du profilé tubulaire fermé 1 sur lequel il s'applique.According to yet another variant of construction, each of the two wings 4 of the C-section 2 may be extended at its free end with a return 16 shown in dashed line at the Figure 1 , return which is oriented outwardly and which matches the shape of the wall 12 of the closed tubular section 1 on which it applies.

Dans le cas où le profilé tubulaire fermé 1 est rond, chaque retour 16 est en conséquence de forme arrondie.In the case where the closed tubular section 1 is round, each return 16 is accordingly rounded.

Dans le cas où le profilé tubulaire fermé est carré ou rectangulaire, chaque retour 16 sera parallèle à l'âme 6 et le profilé 2 en C aura ainsi une section droite dite en Q (Oméga).In the case where the closed tubular section is square or rectangular, each return 16 will be parallel to the core 6 and the profile 2 in C will thus have a cross-section called Q (Omega).

Dans ces derniers exemples où chaque aile 4 est prolongée d'un retour 16, c'est alors bien évidemment l'extrémité libre dudit retour qui sera soudée à la paroi 12 du profilé tubulaire fermé 1.In these last examples where each wing 4 is extended by a return 16, it is then obviously the free end of said return which will be welded to the wall 12 of the closed tubular section 1.

Quelle que soit sa construction retenue pour le profilé 2 en C, ce dernier, en projection transversale, recouvrira en conséquence entre le quart et la moitié de la paroi extérieure 12 du profilé tubulaire fermé 1 et, de préférence, il recouvrira entre 28% et 40% de cette paroi 12.Whatever its construction retained for the profile 2 in C, the latter, in transverse projection, will cover accordingly between the quarter and half of the outer wall 12 of the closed tubular section 1 and, preferably, it will cover between 28% and 40% of this wall 12.

Le poteau selon l'invention ne fait pas que réunir les avantages des poteaux tubulaires fermés, et plus particulièrement le fait qu'ils présentent, à poids égal, de meilleures caractéristiques de résistance à la flexion et à la torsion que les poteaux ouverts, et celui des poteaux ouverts, à savoir que, au cours de leur fabrication, il est aisé de les doter de linguets.The pole according to the invention does not only bring together the advantages of closed tubular poles, and more particularly the fact that they have, at equal weight, better bending and torsion resistance characteristics than open poles, and open poles, that during their manufacture, it is easy to provide pawls.

En effet, en jouant sur une gamme de diamètres de tubes et sur une gamme d'épaisseurs, tant pour le profilé tubulaire fermé que pour le profilé ouvert, on peut aisément parvenir à un poteau présentant le moment d'inertie voulu par l'installateur.Indeed, by playing on a range of pipe diameters and a range of thicknesses, both for the closed tubular section and for the open section, it is easy to reach a pole having the moment of inertia desired by the installer. .

Il est au surplus à noter que le poteau selon l'invention est d'une inertie notablement améliorée, puisque celle-ci s'avère être supérieure à la somme de l'inertie du poteau tubulaire fermé et de l'inertie du poteau ouvert.It is moreover noteworthy that the pole according to the invention has a significantly improved inertia, since it turns out to be greater than the sum of the inertia of the closed tubular pole and the inertia of the open pole.

Un effet de synergie résulte donc de la solidarisation d'un profilé tubulaire fermé et d'un profilé ouvert.A synergistic effect therefore results from the joining of a closed tubular section and an open section.

Comme il va de soi, l'invention ne se limite pas aux seuls modes d'exécution préférentiels décrits ci-dessus.It goes without saying that the invention is not limited to the only preferred embodiments described above.

Elle embrasse au contraire toutes les variantes possibles de réalisation, pour autant que ces dernières ne sortent pas du cadre délimité par les revendications ci-jointes qui définissent la présente invention.On the contrary, it embraces all the possible variants of embodiment, provided that these do not go beyond the scope defined by the appended claims which define the present invention.
