Abstract

The foot (1) consists of two hollow moulded blocks (3, 4) which are hinged together down one side by a tongue (3b) on one block engaging with a slot (4b) on the other. On the opposite side the two blocks are fastened together by an H-shaped key (20) inserted through notches (3d, 4d) into shaped holes (25). The two blocks have concave recesses (13, 14) in their facing surfaces which form a well for the post or mast (2) when they are joined together.

Description

L'invention a trait à un dispositif formant pied pour piquet ou mât, notamment pour pied de tonnelle ou de panneau, et à un procédé de fermeture d'un tel dispositif.The invention relates to a device forming a foot for stake or mast, in particular for arbor or panel base, and to a method for closing such a device.

Les pieds de tonnelle ou de panneau sont généralement constitués par des tubes métalliques ou des mâts en bois d'un diamètre compris entre 18 et 50 mm. Ces pieds peuvent être enfoncés dans le sol pour immobiliser la structure qu'ils supportent. Cependant, il n'est pas toujours possible d'enfoncer ces pieds dans le sol, par exemple, lorsque le sol en question est une terrasse, une route goudronnée ou un gazon qu'il convient de ne pas détériorer.The arbor or panel legs are generally formed by metal tubes or wooden masts of a diameter between 18 and 50 mm. These feet can be sunk into the ground to immobilize the structure they support. However, it is not always possible to press these feet in the ground, for example, when the ground in question is a terrace, a paved road or a lawn that it should not be damaged.

Pour des panneaux, on a parfois recours à des socles en béton qui sont destinés à recevoir l'extrémité inférieure des pieds du panneau. Cependant, de tels socles sont lourds, donc peu pratiques à déplacer, et ne permettent pas de recevoir des pieds ou mâts qui ne sont pas exactement verticaux. Or, il arrive, dans le cas de tonnelles, mais également pour des panneaux comprenant plusieurs pieds formant une structure en forme de pyramide, que des piquets à immobiliser soient inclinés par rapport à la verticale, de sorte qu'il n'existe pas de dispositif adapté pour en constituer le pied.For panels, we sometimes use plinths concrete which are intended to receive the lower end of panel feet. However, such bases are heavy, so impractical to move, and do not allow to receive feet or masts that are not exactly vertical. But he happens, in the case of arbors, but also for panels comprising several feet forming a structure in pyramid shape, that stakes to be immobilized are inclined to the vertical, so that there is no no device adapted to constitute the foot.

En outre, les piquets des dispositifs tels que les tonnelles ou les panneaux d'affichage ont des diamètres variables, voire des sections de formes variables, circulaires, ovales ou polygonales, ce qui peut empêcher l'utilisation de certains socles connus qui ne sont compatibles qu'avec des piquets à section circulaire d'un diamètre déterminé.In addition, the stakes of devices such as arbors or billboards have diameters variables, even sections of variable, circular shapes, oval or polygonal, which may prevent the use of certain known bases which are only compatible with stakes with circular section of a determined diameter.

Ainsi, EP-A-0 380 272 divulgue un dispositif formant pied pour un piquet qui comprend deux parties destinées à être assemblées par des tenons et mortaises disposés autour d'un orifice central prévu pour recevoir essentiellement un poteau vertical de petit diamètre. L'assemblage par tenons et mortaises nécessite la manipulation de pièces lourdes pour engager par en dessus un tenon dans la mortaise correspondante, de part et d'autre de l'orifice ainsi formé.Thus, EP-A-0 380 272 discloses a device forming a foot for a stake which comprises two parts intended to be assembled by tenons and mortises arranged around a central hole designed to receive essentially a pole vertical small diameter. Assembly by tenons and mortises requires the handling of heavy parts to engage from above a tenon in the corresponding mortise, by hand and other of the orifice thus formed.

C'est à ces problèmes qu'entend plus particulièrement remédier l'invention en proposant un dispositif susceptible de s'adapter à des pieds de sections variées, éventuellement inclinés, et ne nécessitant pas de manoeuvre pénible des éléments qui le constituent.It is to these problems that we hear more particularly remedy the invention by proposing a device capable of adapt to feet of various sections, possibly inclined, and not requiring painful operation of the constituent elements.

Dans cet esprit, l'invention concerne un dispositif formant pied pour piquet ou mât, notamment pour pied de tonnelle ou de panneau, comprenant deux cales, de formes complémentaires, destinées à être assemblées en définissant entre elles un puits de réception de ce piquet ou mât, caractérisé en ce que ces cales forment ensemble au moins une zone de réception d'une clé de verrouillage, cette clé étant apte à exercer sur ces cales un effort s'opposant à leur séparation, alors que chaque cale présente une entaille d'introduction de la clé jusqu'à la zone de réception précitée.In this spirit, the invention relates to a device forming foot for stake or mast, in particular for foot of arbor or panel, comprising two wedges, of shapes complementary, intended to be assembled by defining between them a receiving well for this stake or mast, characterized in that these wedges together form at least one zone of reception of a locking key, this key being able to exert on these wedges an effort opposing their separation, while each block has a notch for the introduction of the key to the aforementioned reception area.

Grâce à l'invention, les enveloppes peuvent être mises en place de part et d'autre d'un piquet ou mât en enserrant celui-ci dans le puits qu'elles forment, sans nécessiter de les soulever par rapport au sol sur lequel elles sont posées, puis verrouillées ensemble autour de ce piquet ou mât grâce à la clé qui est aisément mise en place grâce à l'entaille.Thanks to the invention, the envelopes can be put in place on either side of a stake or mast by enclosing it in the well that they form, without needing to lift from the ground on which they are placed, then locked together around this stake or mast using the key which is easily installed thanks to the notch.

Selon un premier aspect avantageux de l'invention, les cales sont des enveloppes creuses obtenues par soufflage, moulage par injection, roto-moulage ou thermoformage de matière plastique. De telles enveloppes sont aisées à manipuler quand elles sont vides et ont un poids suffisant pour remplir leur fonction quand elles sont lestées.According to a first advantageous aspect of the invention, the shims are hollow envelopes obtained by blowing, injection molding, rotational molding or thermoforming of material plastic. Such envelopes are easy to handle when they are empty and have sufficient weight to fill their function when ballasted.

Selon un autre aspect avantageux de l'invention, la clé a globalement une forme de H, chaque branche de la clé étant apte à venir en appui contre une surface de portée externe de l'une des cales. Cette conformation de la clé est particulièrement simple, de sorte que son fonctionnement peut être immédiatement assimilé, y compris par un utilisateur inexpérimenté.According to another advantageous aspect of the invention, the key a globally a form of H, each branch of the key being suitable coming to bear against an external bearing surface of one wedges. This conformation of the key is particularly simple, so that its operation can be immediately assimilated, including by an inexperienced user.

Selon un autre aspect avantageux de l'invention, les cales forment une charnière d'articulation autour d'un axe sensiblement orthogonal à la surface sur laquelle sont posées les cales. Cet aspect de l'invention permet d'emprisonner ou d'enchâsser le piquet au mât entre les cales par pivotement autour de l'axe de la charnière. Dans ce cas, l'une des cales comprend avantageusement au moins une languette apte à pénétrer dans une lumière de l'autre cale, de façon à former cette charnière.According to another advantageous aspect of the invention, the wedges form a hinge of articulation around an axis substantially orthogonal to the surface on which the wedges. This aspect of the invention makes it possible to imprison or to anchor the post to the mast between the wedges by pivoting around the axis of the hinge. In this case, one of the shims advantageously comprises at least one tab capable of penetrating in a light of the other wedge, so as to form this hinge.

Selon un autre aspect avantageux de l'invention, la distance séparant les bords de l'entaille est inférieure à la largeur d'une barre centrale de la clé, prise parallèlement à la direction des branches de cette clé, et supérieure à la largeur de cette barre, prise perpendiculairement à ces branches.According to another advantageous aspect of the invention, the distance between the edges of the cut is less than the width of a central bar of the key, taken parallel to the direction of the branches of this key, and greater than the width of this bar, taken perpendicular to these branches.

Selon un autre aspect avantageux de l'invention, chaque cale comprend, au niveau de la zone de réception, au moins une surface de portée apte à recevoir, en appui, la clé. Avantageusement, la clé est apte à exercer sur ces surfaces de portée un effort tendant à les rapprocher l'une de l'autre ou les unes des autres. On peut également prévoir que la surface de portée de chaque cale est en forme de tronc d'hélice centré sur un orifice prévu pour recevoir une partie de la clé. Ainsi, une rotation de la clé autour de sa partie logée dans l'orifice central permet de faire varier l'effort exercé par la clé sur la ou les surfaces de portée. Dans ce cas, cet orifice central est avantageusement accessible à travers l'entaille de chaque cale. Il est également possible de prévoir que la surface de portée de chaque cale est munie de moyens d'arrêt en rotation de la clé. Ceci garantit un maintien dans le temps du positionnement de la clé.According to another advantageous aspect of the invention, each wedge includes, at the reception area, at least one bearing surface capable of receiving, in support, the key. Advantageously, the key is suitable for exerting on these bearing surfaces a effort to bring them closer to each other or to each other others. It is also possible to provide that the bearing surface of each block is in the form of a propeller trunk centered on a hole designed to receive part of the key. So a rotation of the key around its part housed in the hole central allows you to vary the effort exerted by the key on the bearing surface (s). In this case, this central hole is advantageously accessible through the notch of each hold. It is also possible to provide that the surface of scope of each hold is provided with means of rotation stop of the key. This guarantees that the positioning is maintained over time of the key.

L'invention concerne également un procédé de fermeture d'un dispositif formant pied tel que précédemment décrit qui consiste à :

  • faire pivoter les cales autour d'un axe d'articulation sensiblement orthogonal à la surface sur laquelle elles sont posées et
  • verrouiller les cales par fermeture de l'articulation ainsi formée, en disposant une clé de verrouillage en appui sur des surfaces de portée définies sur chaque cale, de telle sorte que la clé exerce un effort de pincement sur ces surfaces.
The invention also relates to a method for closing a device forming a stand as described above, which consists in:
  • rotate the shims around a hinge axis substantially orthogonal to the surface on which they are placed and
  • locking the wedges by closing the articulation thus formed, by placing a locking key bearing on bearing surfaces defined on each wedge, so that the key exerts a gripping force on these surfaces.

Un tel procédé peut être facilement mis en oeuvre sans nécessiter de soulever les cales constituant le dispositif, c'est-à-dire sans effort trop important.Such a method can be easily implemented without require lifting the wedges constituting the device, that is to say without too much effort.

L'invention sera mieux comprise et d'autres avantages de celle-ci apparaítront plus clairement à la lumière de la description qui va suivre d'un mode de réalisation d'un dispositif formant pied conforme à son principe et de son procédé de fermeture, donnée uniquement à titre d'exemple et faite en référence aux dessins annexés dans lesquels :

  • la figure 1 est une vue en perspective éclatée d'un dispositif formant pied conforme à l'invention ;
  • la figure 2 est une vue en perspective du dispositif de la figure 1 en position montée ;
  • la figure 3 est une coupe selon la ligne III-III à la figure 2 ;
  • la figure 4 est une vue partielle, en élévation et à plus grande échelle, de la zone de réception de la clé de verrouillage du dispositif des figures 1 à 3 et
  • la figure 5 est une coupe selon la ligne V-V à la figure 4.
The invention will be better understood and other advantages of it will appear more clearly in the light of the following description of an embodiment of a device forming a foot conforming to its principle and of its closing process, given solely by way of example and made with reference to the appended drawings in which:
  • Figure 1 is an exploded perspective view of a foot device according to the invention;
  • Figure 2 is a perspective view of the device of Figure 1 in the mounted position;
  • Figure 3 is a section along line III-III in Figure 2;
  • FIG. 4 is a partial view, in elevation and on a larger scale, of the zone for receiving the locking key of the device of FIGS. 1 to 3 and
  • FIG. 5 is a section along the line VV in FIG. 4.

Le dispositif 1 est destiné à être monté à l'extrémité inférieure 2a d'un piquet 2 formé par un tube métallique, tel qu'un piquet du genre mât de tente, constituant le pied d'une tonnelle. Le dispositif 1 comprend deux enveloppes creuses 3 et 4 obtenues par soufflage d'une matière plastique telle que du polyéthylène ou du polypropylène.The device 1 is intended to be mounted at the lower end 2 a of a stake 2 formed by a metal tube, such as a stake of the tent mast type, constituting the foot of an arbor. The device 1 comprises two hollow envelopes 3 and 4 obtained by blowing a plastic material such as polyethylene or polypropylene.

Les enveloppes 3 et 4 peuvent également être réalisées par moulage par injection, roto-moulage, thermoformage ou toute autre méthode de mise en forme d'une matière thermoplastique comportant, éventuellement, une ligne de soudure par ultrasons.Envelopes 3 and 4 can also be produced by injection molding, rotational molding, thermoforming or any other method of shaping a thermoplastic material possibly including an ultrasonic welding line.

Ces enveloppes 3 et 4 sont chacune pourvues d'un orifice non représenté de remplissage, destiné à être obturé par un bouchon tel que le couvercle 30 visible sur l'enveloppe 3. Les enveloppes 3 et 4 peuvent ainsi être partiellement ou complètement remplies d'un matériau M de lestage, tel que du sable, de l'eau ou du ciment.These envelopes 3 and 4 are each provided with an orifice not shown filling, intended to be closed by a cap such as the cover 30 visible on the envelope 3. The envelopes 3 and 4 can thus be partially or completely filled with ballast material M, such as sand, water or cement.

Chaque enveloppe 3 ou 4 définit une zone 13 ou 14 de réception du piquet 2. Comme il ressort plus particulièrement de la figure 1, la zone 13 est formée d'une zone centrale 13a, d'une zone supérieure 13b et d'une zone inférieure 13c, les zones 13b et 13c étant évasées de façon à pouvoir recevoir le piquet 2 avec différentes orientations autour d'un axe X-X', passant par la zone 13a, par rapport à la verticale Z-Z'. La zone de réception 14 présente une géométrie analogue à celle de la zone de réception 13. Les zones 13 et 14 définissent ensemble, entre les enveloppes 3 et 4, un puits 15 de réception de l'extrémité 2a du piquet 2 sensiblement vertical, mais également de l'extrémité d'un piquet incliné, notamment du fait de la géométrie de l'ensemble auquel il appartient, tel qu'une tonnelle, dont les pieds sont généralement inclinés pour une meilleure stabilité. Les enveloppes 3 et 4 constituent donc des cales de blocage du piquet 2.Each envelope 3 or 4 defines a zone 13 or 14 for receiving the stake 2. As is more particularly apparent from FIG. 1, the zone 13 is formed by a central zone 13 a , by an upper zone 13 b and by a lower zone 13 c , the zones 13 b and 13 c being flared so as to be able to receive the stake 2 with different orientations around an axis XX ′, passing through the zone 13 a , with respect to the vertical Z- Z '. The reception area 14 has a geometry similar to that of the reception area 13. The areas 13 and 14 together define, between the envelopes 3 and 4, a well 15 for receiving the end 2 a of the post 2 substantially vertical, but also the end of an inclined stake, in particular due to the geometry of the assembly to which it belongs, such as an arbor, the feet of which are generally inclined for better stability. The envelopes 3 and 4 therefore constitute stakes for blocking the stake 2.

L'enveloppe 3 comprend un bord 3a globalement vertical lorsqu'elle est posée sur une surface horizontale S, telle qu'une terrasse. Ce bord vertical 3a porte une languette 3b destinée à s'engager dans une lumière oblongue 4b ménagée à proximité d'un bord vertical 4a de l'enveloppe 4. Du fait de l'engagement de la languette 3b dans la lumière 4b, il est formé une charnière d'articulation des enveloppes 3 et 4 autour d'un axe vertical Z1-Z'1 parallèle à l'axe Z-Z'. Les enveloppes 3 et 4 peuvent ainsi pivoter autour de l'axe Z1-Z'1 pour emprisonner le piquet 2 dans le puits 15 à la manière de mâchoires.The envelope 3 comprises an edge 3 which is generally vertical when it is placed on a horizontal surface S, such as a terrace. This vertical edge 3 a carries a tongue 3 b intended to engage in an oblong opening 4 b formed near a vertical edge 4 a of the casing 4. Due to the engagement of the tongue 3 b in the light 4 b , there is formed a hinge of articulation of the envelopes 3 and 4 around a vertical axis Z 1 -Z ' 1 parallel to the axis Z-Z'. The envelopes 3 and 4 can thus pivot around the axis Z 1 -Z ' 1 to trap the stake 2 in the well 15 in the manner of jaws.

On note 3c le bord de l'enveloppe 3 opposé au bord 3a et 4c le bord de l'enveloppe 4 opposé au bord 4a. L'emprisonnement du piquet 2 entre les enveloppes 3 et 4 a lieu en rapprochant les bords 3c et 4c alors que la languette 3b est insérée dans la lumière 4b. Ainsi, le diamètre du puits 15 est automatiquement adapté au diamètre du piquet dans la mesure où le rapprochement des bords 3c et 4c a lieu jusqu'à ce que les surfaces des zones 13 et 14 viennent au contact de la surface radiale du piquet 2.We note 3 c the edge of the envelope 3 opposite the edge 3 a and 4 c the edge of the envelope 4 opposite the edge 4 a . The staking of the stake 2 between the envelopes 3 and 4 takes place by bringing the edges 3 c and 4 c together while the tongue 3 b is inserted in the lumen 4 b . Thus, the diameter of the well 15 is automatically adapted to the diameter of the stake insofar as the bringing together of the edges 3 c and 4 c takes place until the surfaces of the zones 13 and 14 come into contact with the radial surface of the stake 2.

Une clé de verrouillage 20 en matière plastique est utilisée pour maintenir les enveloppes 3 et 4 en position serrée ou fermée autour du piquet 2. Cette clé peut également être réalisée en bois ou en métal. La clé 20 a globalement une forme de H et comprend une barre centrale 20a et deux branches 20b et 20c.A locking key 20 made of plastic is used to hold the envelopes 3 and 4 in a tight or closed position around the stake 2. This key can also be made of wood or metal. The key 20 generally has an H shape and comprises a central bar 20 a and two branches 20 b and 20 c .

Chaque enveloppe 3 ou 4 est pourvue d'une entaille 3d ou 4d dans laquelle peut être insérée la partie centrale 20a de la clé 20 selon la direction représentée par les flèches I à la figure 1.Each envelope 3 or 4 is provided with a notch 3 d or 4 d into which the central part 20 a of the key 20 can be inserted in the direction shown by the arrows I in FIG. 1.

L'enveloppe 4 comprend deux surfaces de portée 24 et 24', en forme de tronc d'hélice plane, centrée sur un axe X1-X'1 globalement parallèle à l'axe X-X'. Autour de l'axe X1-X'1, l'entaille 4d de l'enveloppe 4 s'élargit et forme un orifice 25 à section globalement circulaire.The casing 4 comprises two bearing surfaces 24 and 24 ′, in the form of a flat propeller trunk, centered on an axis X 1 -X ′ 1 generally parallel to the axis X-X ′. Around the axis X 1 -X ′ 1 , the notch 4 d of the envelope 4 widens and forms an orifice 25 with a generally circular section.

La barre centrale 20a de la clé 20 a une section globalement rectangulaire. On note L sa largeur parallèlement à la direction des branches 20b et 20c et l sa largeur perpendiculaire à ces branches. La largeur l est inférieure à la distance d séparant les bords des entailles 3d et 4d, cette distance étant inférieure à la largeur L. Ainsi, la clé 20 doit être insérée dans les entailles 3d et 4d avec les branches 20b et 20c orientées parallèlement aux bords des entailles 3d et 4d. Le diamètre de l'orifice 25 est supérieur à la largeur L de la barre 20a, de sorte que lorsque la clé parvient au niveau de cet orifice, celle-ci peut tourner autour de l'axe X1-X'1, comme représenté par la flèche R à la figure 1.The central bar 20 a of the key 20 has a generally rectangular section. We denote by L its width parallel to the direction of the branches 20 b and 20 c and l its width perpendicular to these branches. The width l is less than the distance d separating the edges of the notches 3 d and 4 d , this distance being less than the width L. Thus, the key 20 must be inserted in the notches 3 d and 4 d with the branches 20 b and 20 c oriented parallel to the edges of the notches 3 d and 4 d . The diameter of the orifice 25 is greater than the width L of the bar 20 a , so that when the key reaches the level of this orifice, the latter can turn around the axis X 1 -X ' 1 , as represented by the arrow R in Figure 1.

Du fait de sa rotation R, la clé 20 est tournée de telle sorte que la branche 20c vient en appui contre les surfaces 24 et 24' dans leurs parties 24a et 24'a les plus proches d'un espace interne E défini entre les enveloppes 3 et 4 et visible à la figure 5. La longueur de la barre centrale 20a de la clé 20 est suffisante pour qu'il soit possible de tourner la clé dans cette position quel que soit le diamètre du piquet 2 et la largeur e de l'espace E.Due to its rotation R, the key 20 is turned so that the branch 20 c comes to bear against the surfaces 24 and 24 'in their parts 24 a and 24' a closest to an internal space E defined between envelopes 3 and 4, visible in Figure 5. the length of the central bar 20 has the key 20 is sufficient for it to be possible to turn the key in this position regardless of the diameter of the peg 2 and the width e from space E.

L'enveloppe 3 est équipée de surfaces de portée analogues aux surfaces de portée 24 et 24', dont une seule est visible à la figure 5 avec la référence 23. Cette surface de portée 23 comprend une partie 23a relativement proche de l'espace E et une partie 23b relativement éloignée de l'espace E. Les surfaces 24 et 24' comprennent des parties 24b et 24'b relativement éloignées de l'espace E. Ainsi, une rotation de la clé 20 dans le sens des aiguilles d'une montre à la figure 4 induit un effort de pincement F ou effort de fermeture de la charnière formée par les enveloppes 3 et 4 autour du piquet 2, cet effort étant exercé par les branches 20b et 20c et allant croissant du fait de la géométrie en tronc d'hélice des surfaces 23 et équivalent d'une part, 24 et 24' d'autre part.The envelope 3 is equipped with bearing surfaces similar to the bearing surfaces 24 and 24 ', only one of which is visible in FIG. 5 with the reference 23. This bearing surface 23 comprises a part 23 a relatively close to the space E and a portion 23 b relatively distant from the space E. The surfaces 24 and 24 ′ comprise portions 24 b and 24 ′ b relatively distant from the space E. Thus, a rotation of the key 20 in a clockwise direction of a watch in FIG. 4 induces a pinching force F or closing force of the hinge formed by the envelopes 3 and 4 around the post 2, this force being exerted by the branches 20 b and 20 c and going increasing as a result of the helical trunk geometry of the surfaces 23 and the like on the one hand, 24 and 24 ′ on the other hand.

Dans la position des figures 2 et 3, l'effort de pincement F est exercé sur les surfaces 23 et équivalente, 24 et 24', de part et d'autre de l'orifice 25. Cet effort est un effort élastique du fait des matériaux constitutifs des éléments 3, 4 et 20. Il s'oppose à l'ouverture du puits 15 une fois celui-ci refermé autour du piquet 2 car il tend à rapprocher les surfaces 23 et 24 et les bords 3c et 4c.In the position of FIGS. 2 and 3, the pinching force F is exerted on the surfaces 23 and equivalent, 24 and 24 ', on either side of the orifice 25. This force is an elastic force due to the constituent materials of the elements 3, 4 and 20. It opposes the opening of the well 15 once it is closed around the stake 2 because it tends to bring the surfaces 23 and 24 and the edges 3 c and 4 c closer together.

On comprend qu'il est aisé d'adapter la largeur e de l'espace E au diamètre du piquet 2 en tournant la clé 20 tant que cela est possible, à partir d'une position dans laquelle elle repose contre les parties de surfaces 23a, 24a et équivalentes, vers une position dans laquelle elle repose contre les parties de surfaces 23b, 24b et équivalentes. Ceci permet d'adapter le diamètre du puits 15 et de recevoir des piquets ou mâts 2 dont le diamètre est compris entre 18 et 50 mm.We understand that it is easy to adapt the width e of the space E to the diameter of the stake 2 by turning the key 20 as far as possible, from a position in which it rests against the parts of surfaces 23 a , 24 a and the like, towards a position in which it rests against the parts of surfaces 23 b , 24 b and the like. This makes it possible to adapt the diameter of the well 15 and to receive stakes or masts 2 whose diameter is between 18 and 50 mm.

Les surfaces de portée 23 et équivalente, d'une part, 24 et 24', d'autre part, sont façonnées sur l'extérieur des enveloppes 3 et 4, de telle sorte qu'elles peuvent contribuer à l'aspect esthétique du pied ainsi formé. Ainsi, une zone de raccordement 4e est définie entre la surface externe de l'enveloppe 4 et les surfaces 24 et 24', cette surface pouvant être traitée différemment, en ce qui concerne son état de surface, afin de présenter un aspect particulier.The surfaces of range 23 and equivalent, on the one hand, 24 and 24 ', on the other hand, are shaped on the outside of the envelopes 3 and 4, so that they can contribute to the aesthetic appearance of the foot thus formed. Thus, a connection zone 4 e is defined between the external surface of the casing 4 and the surfaces 24 and 24 ′, this surface being able to be treated differently, with regard to its surface condition, in order to present a particular appearance.

Comme il ressort des figures 1 et 4, les surfaces 24 et 24' sont pourvues de tétons 24c, respectivement 24'c, destinés à constituer des points durs ou des points d'arrêt de la rotation R de la clé 20 autour de l'axe X1-X'1. Des tétons analogues sont prévus sur les surfaces 23 et équivalente. Les branches 20b et 20c peuvent ainsi être bloquées, ce qui évite une rotation de la clé 20 dans le sens inverse des aiguilles d'une montre à la figure 4. L'effort de fermeture F est donc maintenu dans le temps. Les branches 20b et 20c sont, de façon avantageuse mais non obligatoire, pourvues d'encoches 20d de réception des tétons 24c et analogues, ce qui améliore encore l'immobilisation de la clé 20 en rotation, car sa position autour de l'axe X1-X'1 est alors déterminée précisément. Selon une variante non représentée de l'invention, les surfaces 23, 24 et 24' peuvent être graduées pour indiquer l'angle de rotation optimal de la clé 20 en fonction du diamètre nominal du piquet 2.As can be seen in FIGS. 1 and 4, the surfaces 24 and 24 ′ are provided with pins 24 c , respectively 24 ′ c , intended to constitute hard points or stopping points for the rotation R of the key 20 around the 'axis X 1 -X' 1 . Similar studs are provided on surfaces 23 and the like. The branches 20 b and 20 c can thus be blocked, which avoids rotation of the key 20 anticlockwise in FIG. 4. The closing force F is therefore maintained over time. The branches 20 b and 20 c are advantageously but not compulsory, provided with notches 20 d for receiving the nipples 24 c and the like, which further improves the immobilization of the key 20 in rotation, because its position around the axis X 1 -X ' 1 is then determined precisely. According to a variant not shown of the invention, the surfaces 23, 24 and 24 ′ can be graduated to indicate the optimal angle of rotation of the key 20 as a function of the nominal diameter of the stake 2.

On note que les enveloppes 3 et 4 sont globalement symétriques par rapport à un plan passant par le milieu de l'espace E défini entre elles en position montée du dispositif 1 et qu'elles sont plus larges dans leurs parties inférieures que dans leurs parties supérieures, ce qui leur confère une très bonne stabilité, y compris lorsqu'elles sont partiellement remplies.We note that envelopes 3 and 4 are generally symmetrical about a plane passing through the middle of the space E defined between them in the mounted position of the device 1 and are wider in their lower parts than in their upper parts, which gives them a very good stability, even when partially fulfilled.

Dans le cas où le piquet 2 est solidaire d'une toile qui s'étend jusqu'au niveau de son extrémité inférieure, notamment dans le cas d'un pied de tonnelle, cette toile peut être reçue entre les enveloppes 3 et 4, y compris dans l'espace E à l'extérieur du puits 15. En effet, la toile peut facilement être prise "en sandwich" entre les surfaces en regard des enveloppes 3 et 4, sans risque de détérioration.In the case where the stake 2 is integral with a canvas which extends to the level of its lower end, in particular in the case of an arbor stand, this canvas can be received between envelopes 3 and 4, including in space E to outside the well 15. Indeed, the canvas can easily be sandwiched between the surfaces facing the envelopes 3 and 4, without risk of deterioration.

Dans le mode de réalisation décrit, les cales servant au blocage du piquet en position sont des enveloppes creuses. Il est bien entendu que les cales 3 ou 4 peuvent être des pièces pleines et plus généralement, toutes pièces de blocage présentant une géométrie conforme à l'invention. Cependant, l'utilistion d'enveloppes creuses permet d'obtenir des cales pouvant être lestées uniquement sur leur site d'utilisation, voire vidées après utilisation, ce qui présente un avantage considérable pour leur transport et leur manutention.In the embodiment described, the shims used for locking the stake in position are hollow envelopes. he it is understood that the shims 3 or 4 can be parts full and more generally, all blocking parts having a geometry according to the invention. However, the utilistion of hollow envelopes makes it possible to obtain shims which can be ballasted only on their site of use, or even emptied after use, which has a considerable advantage for their transport and handling.
