Description

L'invention concerne le domaine de la fixation d'un élément à fixer au sol, notamment une borne, un poteau ou équivalent. En particulier, il peut s'agir de la fixation d'une borne de recharge électrique, par exemple dédiée à la charge électrique d'un véhicule à traction électrique ou hybride.The invention relates to the field of fixing an element to be fixed to the ground, in particular a terminal, a post or the like. In particular, it may be the fixing of an electric charging station, for example dedicated to the electric charge of a vehicle with electric or hybrid traction.

L'invention a pour objet plus particulièrement un système de fixation d'un élément à fixer au sol, notamment une borne, un poteau ou équivalent, comprenant un mécanisme de réglage du positionnement de l'élément à fixer par rapport au sol, avant son blocage définitif pour l'immobiliser dans le positionnement ainsi réglé. Elle concerne aussi un agencement comprenant un tel système de fixation et un élément à fixer fixé au sol par l'intermédiaire du système de fixation.The subject of the invention is more particularly a system for fixing an element to be fixed to the ground, in particular a terminal, a post or the like, comprising a mechanism for adjusting the positioning of the element to be fixed relative to the ground, before its permanent blocking to immobilize it in the positioning thus adjusted. It also relates to an arrangement comprising such a fixing system and an element to be fixed fixed to the ground by means of the fixing system.

Il est connu une solution consistant à ménager dans le sol un trou de terrassement dans lequel du béton est coulé en laissant en saillie au-dessus du sol les extrémités filetées de canes d'ancrage prises dans le béton. Un socle de la borne, indépendant du reste de la borne notamment constitué par un coffret à fixer sur le socle et par une coiffe à rapporter au moins par-dessus le coffret, est fixé au sol par des boulons vissés sur les parties filetées des canes d'ancrage. Pour permettre un réglage de la position de la borne avant son immobilisation, notamment suivant sa verticalité ou son positionnement en rotation autour d'un axe vertical, des cales sont intercalées entre le sol et le socle avant son serrage. La hauteur des cales en différents endroits doit être ajustées de manière itérative avant d'arriver à un bon positionnement, suivant les conditions de planéité et/ou d'horizontalité du sol.A solution is known which consists in providing an earth hole in the ground into which concrete is poured, leaving the threaded ends of anchor rods caught in the concrete projecting above the ground. A base of the terminal, independent of the rest of the terminal, in particular consisting of a box to be fixed on the base and by a cap to be attached at least over the box, is fixed to the ground by bolts screwed onto the threaded parts of the canes anchor. To allow adjustment of the position of the terminal before it comes to a standstill, in particular according to its verticality or its position in rotation about a vertical axis, shims are inserted between the ground and the base before it is tightened. The height of the wedges in different places must be adjusted iteratively before arriving at a good positioning, according to the conditions of flatness and / or horizontality of the ground.

Cette solution présente les inconvénients suivants :

  • le montage est fastidieux et long,
  • le réglage du positionnement est délicat et peu précis,
  • la solution est peu conviviale et inconfortable pour l'utilisateur,
  • le nombre de pièces est important et difficile tant à gérer qu'à mettre en œuvre.
This solution has the following drawbacks:
  • the assembly is tedious and long,
  • positioning adjustment is delicate and imprecise,
  • the solution is not user-friendly and uncomfortable for the user,
  • the number of parts is large and difficult both to manage and to implement.

Le document FR-A1-2942813 décrit une solution de fixation au sol d'un poteau de signalisation qui comporte un piètement destiné à être fixé au sol et un mât, un corps intermédiaire raccordant le mât au piètement. Le corps intermédiaire comporte une embase solidarisée au piètement par des moyens de fixation, un élément de liaison solidarisé au mât par des moyens d'attache, des montants verticaux raccordant l'embase et l'élément de liaison, et un carter amovible de protection rapporté sur l'embase et l'élément de liaison.The document FR-A1-2942813 describes a solution for fixing to the ground a sign post which comprises a base intended to be fixed to the ground and a mast, an intermediate body connecting the mast to the base. The intermediate body comprises a base secured to the base by fixing means, a connecting element secured to the mast by attachment means, vertical uprights connecting the base and the connecting element, and a removable protective casing attached on the base and the connecting element.

Toutefois cette solution reste peu conviviale et difficile à mettre en œuvre, dans une position inconfortable, notamment en raison de l'accessibilité et de la conception des moyens de fixation. D'autre part, les possibilités de réglage du positionnement de l'ensemble restent limitées. Enfin, cette solution n'est pas applicable au montage d'une borne.However, this solution is not very user-friendly and difficult to implement, in an uncomfortable position, in particular because of the accessibility and the design of the fixing means. Furthermore, the possibilities for adjusting the positioning of the assembly remain limited. Finally, this solution is not applicable to the mounting of a terminal.

Le document WO97/35083A1 décrit un système de fixation d'un ouvrage à fixer au sol, cet ouvrage étant une cabine téléphonique, un poteau de signalisation, un pylône de lignes téléphoniques ou électriques. Il comporte un corps d'appui fixé au sol par l'intermédiaire d'une tige filetée serrée par un écrou. Le diamètre du passage central du corps est plus grand que le diamètre de la tige pour permettre un réglage latéral et angulaire du corps par rapport à la tige, donc par rapport au sol. Une plaque est disposée entre l'ouvrage et le corps, reliée au corps grâce à deux goujons à têtes sphériques vissés dans le corps et deux vis engagées dans le corps. Les deux goujons assurent d'une part le réglage en hauteur et d'autre part l'inclinaison autour d'une première direction horizontale. Les deux vis à tête ronde assurent un réglage d'inclinaison autour d'une deuxième direction horizontale ainsi que le verrouillage de la plaque dans la position voulue. Une possibilité de réglage angulaire du corps autour de la direction verticale est prévue, de même que la possibilité de réglage en translation du corps dans le plan des première et deuxième directions horizontales par rapport au sol.The document WO97 / 35083A1 describes a system for fixing a structure to be fixed to the ground, this structure being a telephone booth, a sign post, a pylon of telephone or electric lines. It comprises a support body fixed to the ground by means of a threaded rod tightened by a nut. The diameter of the central passage of the body is larger than the diameter of the rod to allow lateral and angular adjustment of the body relative to the rod, therefore relative to the ground. A plate is placed between the structure and the body, connected to the body by two studs with spherical heads screwed into the body and two screws engaged in the body. The two studs provide on the one hand the height adjustment and on the other hand the inclination around a first horizontal direction. The two round head screws provide tilt adjustment around a second horizontal direction as well as locking the plate in the desired position. A possibility of angular adjustment of the body around the vertical direction is provided, as is the possibility of adjustment in translation of the body in the plane of the first and second horizontal directions relative to the ground.

Toutefois, cette solution est difficile à mettre en oeuvre en raison du fait que le réglage est mis en œuvre antérieurement à l'assemblage de l'ouvrage sur la plaque. D'autre part, elle est complexe et onéreuse en raison du nombre élevés de pièces nécessaires.However, this solution is difficult to implement due to the fact that the adjustment is implemented prior to assembly of the structure on the plate. On the other hand, it is complex and expensive due to the large number of parts required.

Il reste donc un besoin de trouver une solution alternative qui répond à l'ensemble des problèmes évoqués ci-dessus.There therefore remains a need to find an alternative solution which addresses all of the problems mentioned above.

Le but de la présente invention est de proposer une solution de fixation d'un élément à fixer au sol, notamment une borne, un poteau ou équivalent, qui remédie aux inconvénients listés ci-dessus.The object of the present invention is to propose a solution for fixing an element to be fixed to the ground, in particular a terminal, a post or the like, which overcomes the drawbacks listed above.

Notamment, un objet de l'invention est de fournir une telle solution qui soit simple, facile et rapide à mettre en œuvre, conviviale et confortable, permettant un réglage du positionnement est aisé et précis, tout en étant facile à transporter et à organiser.In particular, an object of the invention is to provide such a solution which is simple, easy and quick to implement, user-friendly and comfortable, allowing positioning adjustment to be easy and precise, while being easy to transport and organize.

Ces objets peuvent être atteints par grâce à un système de fixation d'un élément à fixer au sol, notamment une borne, un poteau ou équivalent, comprenant un mécanisme de réglage du positionnement de l'élément à fixer par rapport au sol selon la revendication 1.These objects can be achieved by means of a system for fixing an element to be fixed to the ground, in particular a terminal, a post or the like, comprising a mechanism for adjusting the positioning of the element to be fixed relative to the ground according to claim 1.

Selon une première alternative, les éléments de fixation entre l'embase de liaison et le sol comprennent :

  • au moins deux éléments filetés mâles solidaires et en saillie du sol selon la première direction,
  • au moins deux lumières oblongues formées dans l'embase de liaison, notamment ayant chacune une forme d'arc de cercle délimitant un secteur angulaire correspondant à une course angulaire suivant laquelle le premier réglage est possible, et chacune traversée par l'un des éléments filetés mâles avec une possibilité de coulissement de sorte à pouvoir mettre en œuvre le premier réglage par coulissement des deux éléments filetés mâles dans les lumières oblongues,

Les éléments d'assemblage entre l'élément à fixer et l'embase de liaison comprennent selon une deuxième alternative :

  • two first sliding elements integral with the connection base, in particular each in the form of a slide, offset with respect to each other in a direction of offset forming an angle with the first direction,
  • two second sliding elements, in particular each in the form of a slide, intended to be integral with the element to be fixed and respectively guided by the first sliding elements in a sliding direction having a component in the first direction,

Selon un mode de réalisation particulier, les premiers et deuxièmes éléments de coulissement et ledit au moins un élément de déplacement sont configurés de sorte que les deux deuxièmes éléments de coulissement peuvent pivoter simultanément autour de la direction de décalage lorsque les éléments de blocage n'assurent pas leur immobilisation, permettant la mise en œuvre d'un réglage du positionnement en rotation de l'élément à fixer autour d'une deuxième direction sensiblement horizontale.According to a particular embodiment, the first and second sliding elements and said at least one displacement element are configured so that the two second sliding elements can pivot simultaneously around the offset direction when the locking elements do not provide not immobilizing them, allowing the implementation of a rotation positioning adjustment of the element to be fixed around a second substantially horizontal direction.

Selon un premier mode de réalisation, ledit au moins un élément de déplacement comporte une vis de pression montée hélicoïdalement sur l'embase de liaison selon une direction de vissage ayant une composante selon la première direction, la vis de pression ayant une extrémité libre, notamment de forme arrondie ou sphérique, en contact avec l'un des deuxième élément de coulissement, notamment au niveau d'une empreinte de centrage formée dans le deuxième élément de coulissement.According to a first embodiment, said at least one displacement element comprises a pressure screw mounted helically on the connection base in a screwing direction having a component in the first direction, the pressure screw having a free end, in particular of rounded or spherical shape, in contact with one of the second sliding element, in particular at the level of a centering imprint formed in the second sliding element.

Selon un autre mode particulier de réalisation, ledit au moins un élément de déplacement comporte au moins une surface de came solidaire d'au moins l'un des deuxièmes éléments de coulissement, configurée de sorte à être contact contre l'embase de liaison et qu'un actionnement en rotation de la surface de came génère un déplacement du deuxième élément de coulissement par rapport à l'embase de liaison en étant guidé par le premier élément de coulissement solidaire de l'embase de liaison.According to another particular embodiment, said at least one displacement element comprises at least one cam surface integral with at least one of the second sliding elements, configured so as to be in contact with the connection base and that '' a rotary actuation of the cam surface generates a displacement of the second sliding element relative to the connecting base being guided by the first sliding element integral with the connecting base.

  • une pièce intermédiaire destinée à former une interface entre l'élément à fixer et l'embase de liaison,
  • des éléments de montage de la pièce intermédiaire sur l'embase de liaison avec une possibilité de réglage du positionnement en rotation de la pièce intermédiaire autour de la deuxième direction et/ou autour de la troisième direction,
  • et des éléments d'accouplement de l'élément à fixer sur la pièce intermédiaire avec une possibilité de réglage du positionnement en translation de l'élément à fixer par rapport à la pièce intermédiaire selon la première direction.
According to a third alternative, the assembly elements between the element to be fixed and the connection base can include:

Selon un mode de réalisation, les éléments de montage sont configurés de sorte à créer une liaison sphérique de la pièce intermédiaire par rapport à l'embase de liaison autour des deuxième et troisième directions, notamment une liaison de type rotule à doigt inhibant la rotation de la pièce intermédiaire par rapport à l'embase de liaison autour de la première direction.According to one embodiment, the mounting elements are configured so as to create a spherical connection of the intermediate piece with respect to the connection base around the second and third directions, in particular a connection of the ball-and-socket type inhibiting the rotation of the intermediate piece with respect to the connection base around the first direction.

L'embase de liaison peut délimiter un passage traversant dirigé sensiblement dans la première direction et destiné à être traversé par des câbles, des gaines ou équivalents s'étendant entre le sol et l'élément à fixer, une ouverture étant formée dans l'embase de liaison dans le plan des deuxième et troisième directions permettant audit passage traversant de déboucher vers l'extérieur de l'embase de liaison dans ledit plan. Préférentiellement, un agencement pourra comprendre un tel système de fixation et une borne fixée au sol par l'intermédiaire du système de fixation, notamment une borne de recharge électrique, dans lequel la borne comprend un socle inférieur assemblé au système de fixation par l'intermédiaire des éléments d'assemblage du système de fixation, un coffret supérieur fixé au socle inférieur et des éléments d'attache notamment par pincement entre le coffret supérieur et le socle inférieur.The connecting base can delimit a through passage directed substantially in the first direction and intended to be crossed by cables, sheaths or the like extending between the ground and the element to be fixed, an opening being formed in the base connecting in the plane of the second and third directions allowing said through passage to lead outwardly of the connecting base in said plane. Preferably, an arrangement may include such a fixing system and a terminal fixed to the ground by means of the fixing system, in particular an electric charging terminal, in which the terminal comprises a lower base assembled to the fixing system by means of elements for assembling the fixing system, an upper box fixed to the lower base and fastening elements in particular by pinching between the upper box and the lower base.

La description suivante, en référence aux figures 1 à 7, concerne un système de fixation 10 d'un élément à fixer au sol (non représenté), notamment une borne, un poteau ou équivalent. Le terme « sensiblement » utilisé dans la suite en référence à une direction donnée correspond à une possibilité angulaire de plus ou moins 10 degrés par rapport à la direction mentionnée.The following description, with reference to Figures 1 to 7 , relates to a fastening system 10 of an element to be fixed to the ground (not shown), in particular a terminal, a post or the like. The term “substantially” used in the following with reference to a given direction corresponds to an angular possibility of plus or minus 10 degrees relative to the direction mentioned.

Pour faciliter la compréhension de la suite de la description, un repère orthonormé est associé au système de fixation 10, la direction longitudinale X du système étant la direction sensiblement horizontale orientée de l'arrière vers l'avant. Sa direction transversale Y correspond à la direction sensiblement horizontale perpendiculaire à la direction X et orientée de la droite vers la gauche. La direction sensiblement verticale Z est perpendiculaire au plan horizontal défini par les directions X et Y et est orientée vers le haut. Pour les deux modes de réalisation, les références numérales et/ou littérales sont conservées pour des éléments identiques d'un mode de réalisation à l'autre.To facilitate understanding of the rest of the description, an orthonormal reference is associated with the fixing system 10, the longitudinal direction X of the system being the substantially horizontal direction oriented from the rear towards the front. Its transverse direction Y corresponds to the substantially horizontal direction perpendicular to the direction X and oriented from right to left. The substantially vertical direction Z is perpendicular to the horizontal plane defined by the directions X and Y and is oriented upwards. For the two embodiments, the numerical and / or literal references are kept for identical elements from one embodiment to another.

Ainsi, le système de fixation 10 comprend un mécanisme de réglage du positionnement de l'élément à fixer par rapport au sol 11. Selon une caractéristique essentielle, le mécanisme de réglage comporte :

  • une embase de liaison 12 destinée à former une interface entre le sol 11 et l'élément à fixer,
  • des éléments de fixation 13 assurant la fixation au sol 11 de l'embase de liaison 12 et configurés de sorte à permettre un premier réglage du positionnement en rotation de l'embase de liaison 12 par rapport au sol 11 autour d'une première direction orientée selon la direction Z sensiblement verticale,
  • et des éléments d'assemblage 14 assurant l'assemblage de l'élément à fixer sur l'embase de liaison 12 et configurés de sorte à permettre un deuxième réglage du positionnement en translation par rapport au sol 11 de l'élément à fixer selon la première direction Z.
Thus, the fixing system 10 comprises a mechanism for adjusting the positioning of the element to be fixed relative to the ground 11. According to an essential characteristic, the adjustment mechanism comprises:
  • a connection base 12 intended to form an interface between the ground 11 and the element to be fixed,
  • fixing elements 13 ensuring the attachment to the ground 11 of the connection base 12 and configured so as to allow a first adjustment of the rotational positioning of the connection base 12 relative to the ground 11 around a first direction oriented in the substantially vertical direction Z,
  • and assembly elements 14 ensuring the assembly of the element to be fixed on the connection base 12 and configured so as to allow a second adjustment of the positioning in translation relative to the ground 11 of the element to be fixed according to the first direction Z.

Avantageusement, les éléments d'assemblage 14 entre l'élément à fixer et l'embase de liaison 12 peuvent être configurés de sorte à permettre en complément et indépendamment l'un de l'autre :

  • un troisième réglage du positionnement en rotation de l'élément à fixer autour d'une deuxième direction orientée selon la direction Y sensiblement horizontale,
  • et/ou un quatrième réglage du positionnement en rotation de l'élément à fixer autour d'une troisième direction orientée selon la direction X sensiblement horizontale, différente de la deuxième direction.
Advantageously, the assembly elements 14 between the element to be fixed and the connection base 12 can be configured so as to allow, in addition and independently of one another:
  • a third adjustment of the rotational positioning of the element to be fixed around a second direction oriented in the substantially horizontal direction Y,
  • and / or a fourth adjustment of the rotational positioning of the element to be fixed around a third direction oriented in the substantially horizontal direction X, different from the second direction.

En outre de possibilités multiples déjà évoquées de réglage en position par rapport au sol 11 de l'élément à fixer, les éléments de fixation 13 entre l'embase de liaison 12 et le sol 11 peuvent avantageusement être configurés de sorte à permettre en complément et indépendamment l'un de l'autre :

  • un cinquième réglage du positionnement en translation de l'embase de liaison 12 par rapport au sol 11 selon la deuxième direction Y,
  • et/ou un sixième réglage du positionnement en translation de l'embase de liaison 12 par rapport au sol selon la troisième direction X,
  • et/ou un septième réglage du positionnement en translation de l'embase de liaison 12 par rapport au sol 11 selon la première direction Z.
In addition to the multiple possibilities already mentioned for adjusting the position in relation to the ground 11 of the element to be fixed, the fixing elements 13 between the connecting base 12 and the ground 11 can advantageously be configured so as to allow, in addition and independently of each other:
  • a fifth adjustment of the positioning in translation of the connecting base 12 relative to the ground 11 in the second direction Y,
  • and / or a sixth adjustment of the positioning in translation of the connecting base 12 relative to the ground in the third direction X,
  • and / or a seventh adjustment of the positioning in translation of the connecting base 12 relative to the ground 11 in the first direction Z.

Grâce aux possibilités de réglage en position de l'embase de liaison 12 autour de Z et avantageusement aussi en translation le long des directions X et/ou Y, les éléments d'assemblage 14 entre l'élément à fixer et l'embase de liaison 12 sont configurés de sorte à inhiber :

  • tout mouvement relatif de l'élément à fixer par rapport à l'embase de liaison 12 en translation selon Y,
  • tout mouvement relatif de l'élément à fixer par rapport à l'embase de liaison en translation selon X,
  • et tout mouvement relatif de l'élément à fixer par rapport à l'embase de liaison en rotation autour de Z.
Thanks to the possibilities of adjusting the position of the connecting base 12 around Z and advantageously also in translation along the X and / or Y directions, the assembly elements 14 between the element to be fixed and the connection base 12 are configured so as to inhibit:
  • any relative movement of the element to be fixed relative to the connecting base 12 in translation along Y,
  • any relative movement of the element to be fixed relative to the connection base in translation along X,
  • and any relative movement of the element to be fixed with respect to the connecting base in rotation around Z.

La manipulation du système de fixation 10 au cours du réglage en position de l'élément à fixer se trouve facilitée, en supprimant les possibilités de réglage d'un même degré de liberté à la fois au niveau des éléments de fixation 13 et des éléments d'assemblage 14.The manipulation of the fixing system 10 during the adjustment in position of the element to be fixed is facilitated, by eliminating the possibilities of adjustment of the same degree of freedom both at the fixing elements 13 and the elements d assembly 14.

Il convient de préciser, dans les définitions générales précédentes de l'invention, que la valeur des angles formés entre les première, deuxième et troisième directions peuvent être différentes de 90 degrés, suivant la conception du système de fixation 10 et les besoins de l'application.It should be noted, in the preceding general definitions of the invention, that the value of the angles formed between the first, second and third directions may be different from 90 degrees, depending on the design of the fixing system 10 and the needs of the application.

La nature des éléments de fixation 13 et de l'embase de liaison 12 est identique pour les premier et deuxième modes de réalisation respectivement représentés sur les figures 1 à 6 et sur la figure 7. Par contre, la nature des éléments d'assemblage 14 entre l'embase de liaison 12 et l'élément à fixer (non représenté) diffèrent entre les premier et deuxième modes de réalisation.The nature of the fastening elements 13 and of the connecting base 12 is identical for the first and second embodiments shown respectively on the figures 1 to 6 and on the figure 7 . By cons, the nature of the connecting elements 14 between the connecting base 12 and the element to be fixed (not shown) differ between the first and second embodiments.

Ainsi dans les premier et deuxième modes de réalisation en référence aux figures 1 à 7, les éléments de fixation 13 entre l'embase de liaison 12 et le sol 11 comprennent au moins deux éléments filetés mâles (non représentés) solidaires et en saillie du sol 11 selon la première direction Z. Au moins deux lumières oblongues 15 sont formées dans l'embase de liaison 12. Chaque lumière oblongue 15 est traversée par l'un des éléments filetés mâles avec une possibilité de coulissement de sorte à pouvoir mettre en œuvre le premier réglage et éventuellement les cinquième, sixième et septième réglages par coulissement des deux éléments filetés mâles dans les lumières oblongues 15. Il s'agit notamment de lumières oblongues 15 ayant chacune une forme d'arc de cercle délimitant un secteur angulaire correspondant à une course angulaire suivant laquelle le premier réglage est possible. Au moins deux écrous de serrage 16 sont prévus, tels que chacun est engagé sur l'un des éléments filetés mâles du côté opposé au sol 11 par rapport à l'embase de liaison 12 : le vissage et le dévissage des écrous de serrage 16 permet respectivement d'assurer ou non une immobilisation de l'embase de liaison 12 par rapport au sol 11.Thus in the first and second embodiments with reference to Figures 1 to 7 , the fastening elements 13 between the connecting base 12 and the ground 11 comprise at least two male threaded elements (not shown) integral and projecting from the ground 11 in the first direction Z. At least two oblong slots 15 are formed in the connecting base 12. Each oblong lumen 15 is crossed by one of the male threaded elements with a sliding possibility so as to be able to implement the first adjustment and possibly the fifth, sixth and seventh adjustments by sliding the two male threaded elements in the oblong slots 15. These are in particular oblong slots 15 having each a form of arc of a circle delimiting an angular sector corresponding to an angular travel according to which the first adjustment is possible. At least two clamping nuts 16 are provided, such that each is engaged on one of the male threaded elements on the side opposite the ground 11 relative to the connection base 12: the screwing and unscrewing of the clamping nuts 16 allows respectively ensuring or not immobilizing the connection base 12 with respect to the ground 11.

Avantageusement, les éléments de fixation 13 entre l'embase de liaison 12 et le sol 11 comprennent en sus au moins deux contre-écrous (non représentés) chacun engagé sur l'un des éléments filetés mâles du côté opposé à l'écrou de serrage 16 par rapport à l'embase de liaison 12. Autrement dit, les contre-écrous sont disposés en dessous de l'embase de liaison 12, entre celle-ci et le sol, contrairement aux écrous de serrage 16 qui sont disposés pour leur part au-dessus de l'embase de liaison de manière à enserrer l'embase 12 en combinaison avec les contre-écrous. La position en hauteur des contre-écrous sur les éléments filetés mâles permet la mise en œuvre du septième réglage.Advantageously, the fastening elements 13 between the connecting base 12 and the ground 11 additionally comprise at least two lock nuts (not shown) each engaged on one of the male threaded elements on the side opposite to the tightening nut. 16 relative to the connection base 12. In other words, the locknuts are arranged below the connection base 12, between the latter and the ground, unlike the tightening nuts 16 which are arranged for their part above the connecting base so as to enclose the base 12 in combination with the locknuts. The height position of the locknuts on the male threaded elements allows the implementation of the seventh adjustment.

Dans un mode de réalisation particulièrement avantageux, l'embase de liaison 12 comprend des éléments de support 17 des écrous de serrage 16 afin de les rendre solidaires de l'embase de liaison 12 de manière réversible lorsqu'ils ne sont pas engagés sur les éléments filetés mâles. Cette caractéristique permet de rendre imperdables les écrous de serrage 16 durant le transport et le stockage du système de fixation 10, de manière générale tant qu'il n'est pas utilisé.In a particularly advantageous embodiment, the connection base 12 comprises support elements 17 of the clamping nuts 16 in order to make them integral with the connection base 12 in a reversible manner when they are not engaged on the elements male threads. This characteristic makes it possible to make the tightening nuts 16 captive during transport and storage of the fastening system 10, in general as long as it is not used.

Une fonction supplémentaire de l'embase de liaison 12 est de fournir un gabarit pour l'utilisateur lorsque ce dernier prévoit l'implantation ultérieure des éléments filetés mâles dans le sol, avant la mise en place du système de fixation 10 et de l'élément à fixer.An additional function of the connection base 12 is to provide a template for the user when the latter provides for the subsequent implantation of the male threaded elements in the ground, before the installation of the fixing system 10 and of the element to fix.

Dans le premier mode de réalisation en référence aux figures 1 à 6, les éléments d'assemblage 14 entre l'élément à fixer et l'embase de liaison 12 comprennent :

  • deux premiers éléments de coulissement 18 solidaires de l'embase de liaison 12, notamment chacun sous la forme d'une coulisse, décalés l'un par rapport à l'autre dans une direction de décalage D formant un angle avec la première direction Z, notamment un angle droit,
  • deux deuxièmes éléments de coulissement 19, notamment chacun sous la forme d'un coulisseau, destinés à être solidaires de l'élément à fixer et respectivement guidés par les premiers éléments de coulissement 18 selon une direction de coulissement C ayant une composante selon la première direction Z.
In the first embodiment with reference to figures 1 to 6 , the assembly elements 14 between the element to be fixed and the connection base 12 comprise:
  • two first sliding elements 18 integral with the connecting base 12, in particular each in the form of a slide, offset with respect to each other in an offset direction D forming an angle with the first direction Z, including a right angle,
  • two second sliding elements 19, in particular each in the form of a slide, intended to be integral with the element to be fixed and respectively guided by the first sliding elements 18 in a sliding direction C having a component in the first direction Z.

En particulier, il est possible de prévoir que les coulisses constitutives des premiers éléments de coulissement 18 soient orientées dans la direction Z de sorte à imposer une direction de coulissement C aux deuxièmes éléments de coulissement 19 selon la direction Z. La direction de décalage D est notamment orientée dans la direction Y.In particular, it is possible to provide for the slides constituting the first sliding elements 18 to be oriented in the direction Z so as to impose a sliding direction C on the second sliding elements 19 in the direction Z. The offset direction D is especially oriented in direction Y.

Toujours dans le premier mode de réalisation en référence aux figures 1 à 6, les éléments d'assemblage 14 entre l'élément à fixer et l'embase de liaison 12 comprennent également au moins un élément de déplacement 20 solidaire de l'embase de liaison 12 et/ou de l'élément à fixer. L'élément de déplacement 20 est configuré de sorte à ajuster la position relative des deuxièmes éléments de coulissement 19 par rapport aux premiers éléments de coulissement 18 dans la direction de coulissement C. Cet ajustement permet la mise en œuvre du deuxième réglage et éventuellement du quatrième réglage tels que définis ci-dessus. Des éléments de blocage 21, tels qu'un écrou de serrage vissé sur chacun des deuxièmes éléments de coulissement 19, permettent respectivement d'assurer ou non une immobilisation des deuxièmes éléments de coulissement 19 par rapport aux premiers éléments de coulissement 18 après réglage.Still in the first embodiment with reference to figures 1 to 6 , the connecting elements 14 between the element to be fixed and the connection base 12 also comprise at least one displacement element 20 integral with the connection base 12 and / or the element to be fixed. The displacement element 20 is configured so as to adjust the relative position of the second sliding elements 19 relative to the first sliding elements 18 in the sliding direction C. This adjustment allows the implementation of the second adjustment and possibly the fourth adjustment as defined above. Locking elements 21, such as a clamping nut screwed onto each of the second sliding elements 19, make it possible respectively to ensure or not to immobilize the second sliding elements 19 relative to the first sliding elements 18 after adjustment.

Avantageusement, les premiers et deuxièmes éléments de coulissement 18, 19 et l'élément de déplacement 20 sont configurés de sorte que les deux deuxièmes éléments de coulissement 19 peuvent pivoter simultanément autour de la direction de décalage D lorsque les éléments de blocage 21 n'assurent pas leur immobilisation, permettant la mise en œuvre du troisième réglage tel que défini préalablement. Dans la variante particulière du premier mode de réalisation en aucun cas limitative, l'élément de déplacement 20 comporte une vis de pression montée hélicoïdalement sur l'embase de liaison 12 selon une direction de vissage V correspondant à la direction de coulissement C et ayant de ce fait une composante selon la première direction Z. La vis de pression présente une extrémité libre 32 orientée vers le haut, notamment de forme arrondie ou sphérique, en contact avec l'un des deuxième éléments de coulissement 19, notamment au niveau d'une empreinte de centrage 22 formée dans le deuxième élément de coulissement 19. Chaque vis de pression est déplaçable selon sa direction de vissage V, parallèlement à la direction de coulissement C, par l'intermédiaire d'un écrou 24 dont l'actionnement en rotation peut être facilité par un orifice 25 adapté à la mise en place d'un outil tel qu'un tournevis. Les empreintes de centrage 22 agencées dans les deux éléments de coulissement 19 prennent chacune la forme d'une rainure, les deux rainures étant agencées selon une même direction correspondant à la direction de décalage D et finalement à la direction de réglage selon Y par coulissement rainure/vis. Autrement dit, la possibilité de coulissement des empreintes de centrage 22 sur les extrémités 32 des vis de pression dans la direction Y permet à l'élément à fixer de coulisser selon Y par rapport à l'embase de liaison 12 et donc par rapport au sol 11. Ceci correspond au cinquième réglage tel que défini précédemment. Ces dispositions sont représentées en particulier sur les figures 4 et 5. Pour permettre la mise en œuvre du troisième réglage tel que défini préalablement, chaque empreinte de centrage 22 pivote autour de la direction Y autour de l'extrémité libre 32 correspondante dans la limite des flancs de l'empreinte 22 de telle façon à pouvoir gagner un mouvement de liberté de l'élément à fixer selon une rotation autour de Y.Advantageously, the first and second sliding elements 18, 19 and the displacement element 20 are configured so that the two second sliding elements 19 can pivot simultaneously around the offset direction D when the locking elements 21 do not provide not immobilize them, allowing the implementation of the third adjustment as defined previously. In the particular variant of the first embodiment which is in no way limiting, the displacement element 20 comprises a pressure screw mounted helically on the connection base 12 in a screwing direction V corresponding to the sliding direction C and having this makes a component in the first direction Z. The pressure screw has a free end 32 oriented upwards, in particular of rounded or spherical shape, in contact with one of the second sliding elements 19, in particular at a centering imprint 22 formed in the second sliding element 19. Each pressure screw is movable in its screwing direction V, parallel to the sliding direction C, by means of a nut 24 whose actuation in rotation can be facilitated by an orifice 25 adapted to the installation of a tool such as a screwdriver. The centering impressions 22 arranged in the two sliding elements 19 each take the form of a groove, the two grooves being arranged in the same direction corresponding to the offset direction D and finally to the direction of adjustment according to Y by groove / screw sliding. In other words, the possibility of sliding the centering impressions 22 on the ends 32 of the pressure screws in the direction Y allows the element to be fixed to slide along Y relative to the connecting base 12 and therefore relative to the ground 11. This corresponds to the fifth setting as defined above. These provisions are represented in particular on the figures 4 and 5 . To allow the implementation of the third adjustment as defined previously, each centering imprint 22 pivots around the direction Y around the corresponding free end 32 within the flanks of the imprint 22 so as to be able to gain a freedom movement of the element to be fixed according to a rotation around Y.

Par ailleurs, la possibilité de coulissement selon Z de chacun des deuxièmes éléments de coulissement 19 indépendamment l'un de l'autre permet de réaliser un éventuel réglage du positionnement en rotation de l'élément à fixer autour de la direction X par rapport à l'embase de liaison 12, et donc par rapport au sol 11. Ceci correspond au quatrième réglage tel que défini précédemment.Furthermore, the possibility of sliding along Z of each of the second sliding elements 19 independently of one another makes it possible to carry out any adjustment of the positioning in rotation of the element to be fixed around the direction X relative to the 'connecting base 12, and therefore relative to the ground 11. This corresponds to the fourth adjustment as defined above.

En référence en particulier à la figure 6 maintenant, ledit au moins un élément de déplacement 20 peut alternativement comporter au moins une surface de came 23 solidaire d'au moins l'un des deuxièmes éléments de coulissement 19, voire des deux. Chaque surface de came 23 est configurée de sorte à être contact contre l'embase de liaison 12 et qu'un actionnement en rotation de la surface de came 23 génère un déplacement du deuxième élément de coulissement 19 par rapport à l'embase de liaison 12 en étant guidé par le premier élément de coulissement 18 lui-même solidaire de l'embase de liaison 12. Pour cela, la surface de came 23 peut être montée à pivotement par l'intermédiaire d'un axe 34 par rapport au deuxième élément de coulissement 19 correspondant. Ce montage à pivotement de la came peut ensuite être éventuellement supprimé en serrant l'écrou 21 solidaire de l'élément de coulissement 19.With particular reference to the figure 6 now, said at least one displacement element 20 may alternatively comprise at least one cam surface 23 integral with at least one of the second sliding elements 19, or even of the two. Each cam surface 23 is configured so as to be in contact with the connection base 12 and that actuation in rotation of the cam surface 23 generates a displacement of the second sliding element 19 relative to the connection base 12 being guided by the first sliding element 18 which is itself integral with the connecting base 12. For this, the cam surface 23 can be pivotally mounted by means of an axis 34 relative to the second element of slide 19 corresponding. This pivoting mounting of the cam can then be optionally eliminated by tightening the nut 21 secured to the sliding element 19.

Dans le deuxième mode de réalisation en référence à la figure 7, à la différence du premier mode, les éléments d'assemblage 14 entre l'élément à fixer et l'embase de liaison 12 comprennent :

  • une pièce intermédiaire 26 destinée à former une interface entre l'élément à fixer et l'embase de liaison 12,
  • des éléments de montage 27 de la pièce intermédiaire 26 sur l'embase de liaison 12 avec une possibilité de réglage du positionnement en rotation de la pièce intermédiaire 26 autour de la direction Y et/ou autour de la direction X,
  • et des éléments d'accouplement 28 de l'élément à fixer sur la pièce intermédiaire 26 avec une possibilité de réglage du positionnement en translation de l'élément à fixer par rapport à la pièce intermédiaire 26 selon la direction Z.
In the second embodiment with reference to the figure 7 , unlike the first mode, the assembly elements 14 between the element to be fixed and the connection base 12 comprise:
  • an intermediate part 26 intended to form an interface between the element to be fixed and the connection base 12,
  • mounting elements 27 of the intermediate piece 26 on the connecting base 12 with a possibility of adjusting the rotational positioning of the intermediate piece 26 around the direction Y and / or around the direction X,
  • and coupling elements 28 of the element to be fixed on the intermediate part 26 with a possibility of adjusting the positioning in translation of the element to be fixed relative to the intermediate part 26 in the direction Z.

Avantageusement, les éléments de montage 27 sont configurés de sorte à créer une liaison sphérique de la pièce intermédiaire 26 par rapport à l'embase de liaison 12 autour des deuxième et troisième directions Y, X. Il s'agit notamment d'une liaison de type rotule à doigt inhibant la rotation de la pièce intermédiaire 26 par rapport à l'embase de liaison 12 autour de la direction Z.Advantageously, the mounting elements 27 are configured so as to create a spherical connection of the intermediate piece 26 relative to the connection base 12 around the second and third directions Y, X. This is in particular a connection of type finger ball joint inhibiting the rotation of the intermediate part 26 relative to the connecting base 12 around the direction Z.

Dans les premiers et deuxième modes de réalisation, l'embase de liaison 12 délimite un passage traversant 29 dirigé sensiblement dans la première direction Z et destiné à être traversé par des câbles 30, des gaines ou équivalents s'étendant entre le sol 11 et l'élément à fixer. Une ouverture 31 peut être formée dans l'embase de liaison 12 dans le plan (X, Y) des deuxième et troisième directions permettant au passage traversant 29 de déboucher vers l'extérieur de l'embase de liaison 12 dans ce plan, ce qui facilite la mise en place des câbles 30 dans l'embase de liaison 12, ou réciproquement. Lorsque l'embase de liaison 12 adopte une forme générale annulaire, l'ouverture correspond à une discontinuité du périmètre de cet anneau sur un angle donné, par exemple de l'ordre de 80 degrés.In the first and second embodiments, the connection base 12 delimits a through passage 29 directed substantially in the first direction Z and intended to be crossed by cables 30, sheaths or the like extending between the ground 11 and l element to fix. An opening 31 can be formed in the connection base 12 in the plane (X, Y) of the second and third directions allowing passage crossing 29 to open outwardly from the connection base 12 in this plane, which facilitates the placement of cables 30 in the connection base 12, or vice versa. When the connecting base 12 adopts a generally annular shape, the opening corresponds to a discontinuity in the perimeter of this ring over a given angle, for example of the order of 80 degrees.

L'invention porte aussi sur un agencement comprenant un système de fixation 10 et un élément à fixer fixé au sol 11 par l'intermédiaire du système de fixation 10. L'élément à fixer est avantageusement une borne, notamment une borne de recharge électrique, car le système de fixation répond aux problématiques spécifiques de fixation liées au domaine des bornes. Toutefois, il pourrait être envisagé que le système de fixation 10 puisse être utilisé dans le cadre de la fixation au sol d'un poteau ou d'un potelet par exemple.The invention also relates to an arrangement comprising a fixing system 10 and an element to be fixed fixed to the ground 11 by means of the fixing system 10. The element to be fixed is advantageously a terminal, in particular an electric charging terminal, because the fastening system responds to specific fastening issues related to the field of terminals. However, it could be envisaged that the fixing system 10 could be used within the framework of the fixing to the ground of a pole or a post for example.

La borne peut notamment comprendre un socle inférieur 33 assemblé au système de fixation 10 par l'intermédiaire des éléments d'assemblage 14 du système de fixation 10, un coffret supérieur (non représenté) fixé au socle inférieur 33 et des éléments d'attache notamment par pincement entre le coffret supérieur et le socle inférieur 33.The terminal may in particular comprise a lower base 33 assembled to the fastening system 10 by means of the assembly elements 14 of the fastening system 10, an upper box (not shown) fixed to the lower base 33 and fastening elements in particular by pinching between the upper box and the lower base 33.

La fixation de l'élément à fixer au sol 10 peut se faire par la mise en œuvre des étapes suivantes :

  • fixer l'embase de liaison 12 au sol 11 en réalisant un premier réglage du positionnement en rotation de l'embase de liaison 12 par rapport au sol 11 autour de la première direction Z sensiblement verticale,
  • immobiliser l'embase de liaison 12 par rapport au sol 11 après la mise en œuvre du premier réglage, par exemple en actionnant les écrous de serrage 16,
  • assembler l'élément à fixer sur l'embase de liaison 12 en réalisant un deuxième réglage du positionnement en translation par rapport au sol 11 de l'élément à fixer selon la première direction Z,
  • immobiliser l'élément à fixer par rapport à l'embase de liaison 12 après la mise en œuvre de ce deuxième réglage.
The element to be fixed to the ground 10 can be fixed by implementing the following steps:
  • fix the connection base 12 to the ground 11 by making a first adjustment of the rotational positioning of the connection base 12 relative to the ground 11 around the first substantially vertical direction Z,
  • immobilize the connection base 12 with respect to the ground 11 after the implementation of the first adjustment, for example by actuating the tightening nuts 16,
  • assemble the element to be fixed on the connection base 12 by performing a second adjustment of the positioning in translation relative to the ground 11 of the element to be fixed in the first direction Z,
  • immobilize the element to be fixed relative to the connecting base 12 after the implementation of this second adjustment.

Ainsi, le deuxième réglage est avantageusement mis en œuvre dans le même temps que l'assemblage de l'élément à fixer sur l'embase de liaison par l'intermédiaire des éléments d'assemblage 14, contrairement à l'art antérieur où tous les réglages étaient réalisés avant l'assemblage de l'élément à fixer.Thus, the second adjustment is advantageously implemented at the same time as the assembly of the element to be fixed on the connection base via the assembly elements 14, unlike the prior art where all the adjustments were made before assembling the element to be fixed.

De manière générale, il pourra être réalisé les phases successives suivantes :

  • poser le socle 33 sur le sol 11 et sert de gabarit de perçage pour placer les trois tiges au sol : même si les câbles 30 sortent en biais et de manière erratique, l'ouverture 31 permet leur passage et leur mise en place à travers l'embase 12,
  • disposer des contre-écrous (ou des cales) sous l'embase de liaison 12, dont la hauteur par rapport au sol permet de faire un réglage en hauteur de l'embase 12,
  • mettre en place les écrous 16 et les pré-serrer sur les tiges,
  • mettre en place le socle 33 sur les éléments de coulissement de l'embase 12,
  • régler en rotation autour de Z grâce aux lumières 15 à travers lesquelles passent les tiges hors du sol,
  • serrer les écrous de serrage 16,
  • ajuster de manière plus fine le positionnement du socle en hauteur, sans la démonter, en faisant coulisser les premiers et deuxième éléments de coulissement les uns par rapport aux autres,
  • et ajuster de manière plus fine le positionnement du socle en rotation autour de Y et/ou autour de X grâce à la manipulation des écrous 21 sur les éléments de coulissement, éventuellement les surfaces de came 23.
In general, the following successive phases can be carried out:
  • place the base 33 on the ground 11 and serves as a drilling template to place the three rods on the ground: even if the cables 30 come out at an angle and erratically, the opening 31 allows their passage and their establishment through the '' base 12,
  • have locknuts (or shims) under the connecting base 12, the height of which relative to the ground makes it possible to adjust the height of the base 12,
  • place the nuts 16 and pre-tighten them on the rods,
  • put the base 33 on the sliding elements of the base 12,
  • adjust in rotation around Z thanks to the lights 15 through which the rods pass out of the ground,
  • tighten the clamping nuts 16,
  • fine-tune the positioning of the base in height, without dismantling it, by sliding the first and second sliding elements relative to each other,
  • and fine-tune the positioning of the rotating base around Y and / or around X by manipulating the nuts 21 on the sliding elements, possibly the cam surfaces 23.

Il en résulte que durant l'assemblage de la borne sur l'embase de liaison, les réglages du positionnement du socle de la borne en hauteur et en rotation autour de Y et/ou autour de Y sont très avantageusement mis en œuvre après la mise en place et le serrage du socle sur l'embase de liaison. Ceci facilite beaucoup la mise en œuvre de la solution.It follows that during the assembly of the terminal on the connection base, the adjustments of the positioning of the base of the terminal in height and in rotation around Y and / or around Y are very advantageously implemented after the setting in place and tightening the base on the connection base. This greatly facilitates the implementation of the solution.

De manière plus générale, quelle que soit la nature de l'élément à fixer, le système de fixation est configuré de sorte que l'assemblage de l'élément à fixer sur l'embase de liaison 12 est mis en œuvre tout en réalisant le deuxième réglage du positionnement en translation de l'élément à fixer selon la première direction Z. Plus précisément, les éléments d'assemblage de chacune des deux variantes décrites précédemment permettent chacun de s'assurer que l'assemblage de l'élément à fixer sur l'embase de liaison 12 est réalisé en même temps que la mise en œuvre du deuxième réglage du positionnement en translation de l'élément à fixer selon la première direction Z. L'élément à fixer étant en place en vue de sa fixation et au moment du réglage permet de faciliter considérablement la facilité et la qualité de réglage de la position en translation de l'élément à fixer selon la première direction Z.More generally, whatever the nature of the element to be fixed, the fixing system is configured so that the assembly of the element to be fixed on the connection base 12 is implemented while carrying out the second adjustment of the positioning in translation of the element to be fixed in the first direction Z. More specifically, the assembly elements of each of the two variants described above each make it possible to ensure that the assembly of the element to be fixed on the connecting base 12 is produced at the same time as the implementation of the second adjustment of the translation positioning of the element to be fixed in the first direction Z. The element to be fixed being in place for its fixing and at adjustment time greatly facilitates the ease and quality of adjustment of the translational position of the element to be fixed in the first direction Z.

Un avantage supplémentaire est que la solution est simple car le nombre de pièces utilisées est faible. Par ailleurs, les mêmes éléments sont utilisés pour mettre en œuvre l'assemblage de l'élément à fixer et le deuxième réglage, et éventuellement les troisième et quatrième réglages.An additional advantage is that the solution is simple because the number of parts used is small. Furthermore, the same elements are used to implement the assembly of the element to be fixed and the second adjustment, and possibly the third and fourth adjustments.
