Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

La présente invention a trait généralement aux dispositifs de support et plus particulièrement à un dispositif de support ancrable dans le sol servant à maintenir un objet fixement au-dessus du sol.The present invention generally relates to support devices and more particularly to a support device anchorable in the ground for holding an object fixed above the ground.

ÉTAT DE LA TECHNIOUESTATE OF THE ART

Des dispositifs de support pouvant être ancrés dans le sol existent sous de nombreuses formes. Une inspection de l'art antérieur révèle l'existence de nombreux dispositifs pouvant être ancrés dans le sol, plus particulièrement dans un sol de composition granulaire quelconque, tel que dans la terre, du sable, de la neige, ou autre. Pour alléger le texte, on utilisera à l'occasion la terre comme composition exemplaire. Un grand nombre de dispositifs de support existent et diffèrent essentiellement par la géométrie de l'embout du support destiné à être enfoncé dans le sol.Support devices that can be anchored in the ground exist in many forms. An inspection of the prior art reveals the existence of numerous devices that can be anchored in the ground, more particularly in a soil of any granular composition, such as in the ground, sand, snow, or other. To lighten the text, the earth will occasionally be used as an exemplary composition. A large number of support devices exist and differ essentially by the geometry of the end of the support intended to be driven into the ground.

Parmi ces dispositifs, nous nous intéresserons aux dispositifs de support qui comprennent une tige tubulaire à section creuse qui s'érige verticalement un fois ancrée dans le sol. L'extrémité inférieure de la tige destinée à être ancrée dans le sol comprend une ouverture inférieure et un filet sous forme d'une lame ou une barre hélicoïdale pointue ayant la même forme qu'un ressort non contraint, constituant le moyen de vissage dans le sol. L'extrémité supérieure comprend une ouverture de fixation dans laquelle il est possible de fixer un objet quelconque tel que le poteau d'un parasol, par exemple. En enfonçant le dispositif de support dans le sol par l'ouverture inférieure, la terre peut pénétrer dans la tige tubulaire du support par son extrémité inférieure, ce qui permet à la tige de s'enfoncer plus facilement, la terre n'ayant pas à être tassée au fur et à mesure que le dispositif est vissé dans le sol, comme c'est le cas par exemple avec une tige à extrémité inférieure fermée de forme conique. Cependant, lorsque la terre pénètre et s'entasse dans le corps tubulaire de la tige, il peut être difficile de la déloger. Si le dispositif est utilisé une deuxième fois sans avoir évacué la colonne de terre précédemment formée, une nouvelle colonne de terre viendra se former et forcera la vieille colonne de terre vers le haut de la tige tubulaire; si le dispositif est utilisé de nombreuses fois de cette façon, la tige tubulaire peut se retrouver remplie de terre sur toute sa longueur jusqu'à ce que la terre obstrue l'ouverture de fixation à l'extrémité supérieure de la tige, empêchant la fixation de l'objet tel que le parasol.Among these devices, we will focus on support devices that include a tubular rod with hollow section that rises vertically once anchored in the ground. The lower end of the rod intended to be anchored in the ground comprises a lower opening and a net in the form of a blade or a pointed helical bar having the same shape as an unconstrained spring constituting the screwing means in the ground. The upper end comprises a fastening opening in which it is possible to fix any object such as the post of an umbrella, for example. By pushing the support device into the ground through the lower opening, the soil can penetrate the tubular shaft of the support by its lower end, which allows the rod to sink more easily, the earth not having to to be compacted as the device is screwed into the ground, as is the case for example with a closed bottom end rod conical. However, when the earth penetrates and piles up in the tubular body of the stem, it can be difficult to dislodge it. If the device is used a second time without having evacuated the previously formed column of soil, a new column of soil will form and force the old column of soil up the tubular shaft; if the device is used many times in this way, the tubular shaft may become filled with soil all the way through until the soil obstructs the attachment opening at the upper end of the stem, preventing fixation of the object such as the parasol.

Le brevet américain No. 6,202,368(ci-après le brevet « Wallace ») montre un dispositif ancrable au sol, comprenant un poteau tubulaire muni d'une extrémité supérieure ouverte et d'une extrémité inférieure ouverte, d'une lame de vissage fixement attachée à la portion inférieure de ce poteau, et muni au surplus de deux orifices intermédiaires. Les orifices selon le brevet Wallace sont destinés être engagés par un outil de vissage.U.S. Patent No. 6,202,368 (hereinafter the "Wallace" patent ) shows a ground anchoring device comprising a tubular pole having an open top end and an open bottom end, a fixed attachment screw blade. at the lower portion of this post, and provided in addition with two intermediate orifices. The orifices according to the Wallace patent are intended to be engaged by a screwing tool.

SOMMAIRE DE L'INVENTIONSUMMARY OF THE INVENTION

DESCRIPTION DÉTAILLÉE DES RÉALISATIONS DE L'INVENTIONDETAILED DESCRIPTION OF THE ACHIEVEMENTS OF THE INVENTION

Les Figures 1 à 4 montrent le dispositif de support 10 de l'invention, qui est destiné à être utilisé sur un sol S de composition granulaire, et qui a pour objectif de supporter un objet ne faisant pas partie de l'invention, comme un parasol par exemple, fixement au-dessus du sol.The Figures 1 to 4 show the support device 10 of the invention, which is intended to be used on a soil S of granular composition, and which aims to support an object not forming part of the invention, such as a parasol for example, fixedly above ground.

Le dispositif de support 10 comprend une tige à section tubulaire creuse 12 qui définit deux extrémités : une extrémité inférieure correspondant à l'extrémité qui peut être ancrée dans le sol S, et une extrémité supérieure, opposée à l'extrémité inférieure.The support device 10 comprises a hollow tubular section rod 12 which defines two ends: a lower end corresponding to the end which can be anchored in the ground S, and an upper end, opposite to the lower end.

Une ouverture inférieure 14 est présente à l'extrémité inférieure de la tige 12. Une ouverture supérieure 16 est présente à l'extrémité supérieure de la tige 12.A lower opening 14 is present at the lower end of the rod 12. An upper opening 16 is present at the upper end of the rod 12.

Une barre hélicoïdale pointue 22 est fixement attachée à la portion inférieure de la tige 12, tel qu'illustré sur la Figure 1. Cette barre hélicoïdale 22 représente un moyen de vissage du dispositif 10. La barre hélicoïdale 22 est destinée à aider l'utilisateur du dispositif 10 à ancrer le dispositif 10 dans le sol S. Le rôle de la barre hélicoïdale 22 s'apparente à celui des filets d'une vis. Une portion inférieure convergente 22a de la barre hélicoïdale 22 dépasse vers le bas l'extrémité inférieure de la tige 12 pour faciliter l'ancrage du dispositif 10 dans le sol S. Une fois que la portion inférieure 22a de la barre hélicoïdale 22 est enfoncée dans le sol S, la portion de la tige 12 entourée par la barre hélicoïdale 22 peut à son tour pénétrer dans le sol S plus aisément. Puisque le corps de la tige 12 elle-même est cylindrique et creux, la surface effective résistant à l'enfoncement est très faible.A pointed helical bar 22 is fixedly attached to the lower portion of the rod 12, as shown in FIG. Figure 1 . This helical bar 22 represents a means of screwing the device 10. The helical bar 22 is intended to help the user of the device 10 to anchor the device 10 in the ground S. The role of the helical bar 22 is similar to that of the threads of a screw. A convergent lower portion 22a of the helical bar 22 projects downwardly from the lower end of the rod 12 to facilitate the anchoring of the device 10 in the ground S. Once the lower portion 22a of the helical bar 22 is depressed in the soil S, the portion of the rod 12 surrounded by the helical bar 22 can in turn penetrate the soil S more easily. Since the body of the rod 12 itself is cylindrical and hollow, the effective surface resistant to depression is very small.

La tige 12 présente un orifice intermédiaire 18 sur son flanc, entre les ouvertures 14 et 16 et espacé de celles-ci.The rod 12 has an intermediate orifice 18 on its side, between the openings 14 and 16 and spaced therefrom.

De plus, la tige 12 est munie d'un déflecteur 24 sous forme d'une plaque métallique ovale, le déflecteur 24 étant fixé à l'intérieur du corps creux de la tige 12, et son rebord périphérique épousant la paroi intérieure de la tige 12. Le déflecteur 24 est disposé obliquement à l'intérieur de la tige 12 de façon à ce qu'il fasse face à l'orifice 18 de manière inclinée. La partie la plus haute du déflecteur 24 est alignée avec la partie supérieure du contour de l'orifice 18.In addition, the rod 12 is provided with a deflector 24 in the form of an oval metal plate, the deflector 24 being fixed inside the hollow body of the rod 12, and its peripheral rim conforming to the inner wall of the rod 12. The deflector 24 is disposed obliquely inside the rod 12 so that it faces the orifice 18 in an inclined manner. The highest part of the deflector 24 is aligned with the upper part of the contour of the orifice 18.

Un bras de vissage allongé 20 est attaché de façon pivotante sur la tige 12 par une de ses extrémités. Le point d'attache entre le bras 20 et la tige 12 est localisé entre l'orifice 18 et l'ouverture supérieure16, par exemple directement au-dessus de l'orifice 18 tel qu'illustré. Ce bras 20 peut pivoter entre deux positions limites : une position repliée, où le bras 20 est parallèle à la tige 12, et où l'extrémité libre du bras 20 est orienté vers le haut de la tige 12, comme le montre la Figure 1; et une position opérationnelle déployée, où le bras 20 est perpendiculaire à la tige 12, comme le montre la Figure 2. Ce bras 20 va faciliter la rotation du dispositif 10 autour de son axe de symétrie central. Le bras 20 est donc un bras de levier favorisant l'application d'un moment de rotation dans la tige 12, et donc le vissage du dispositif 10 dans le sol S.An elongated screw arm 20 is pivotally attached to the shaft 12 at one end thereof. The point of attachment between the arm 20 and the rod 12 is located between the orifice 18 and the upper opening 16, for example directly above the orifice 18 as illustrated. This arm 20 can pivot between two limit positions: a folded position, where the arm 20 is parallel to the rod 12, and where the free end of the arm 20 is oriented towards the top of the rod 12, as shown in FIG. Figure 1 ; and an extended operational position, where the arm 20 is perpendicular to the rod 12, as shown in FIG. Figure 2 . This arm 20 will facilitate the rotation of the device 10 around its central axis of symmetry. The arm 20 is therefore a lever arm favoring the application of a moment of rotation in the rod 12, and thus the screwing of the device 10 in the ground S.

Deux vis de serrage 26 et 27 sont présentes sur la tige 12. Ces deux vis 26 et 27 se trouvent face à face et à des positions diamétralement opposées sur la tige 12. Les vis 26 et 27 ont pour but de maintenir en place par serrage un objet inséré dans la section creuse de la tige 12 par l'ouverture 16, par exemple l'extrémité inférieure du poteau d'un parasol.Two clamping screws 26 and 27 are present on the rod 12. These two screws 26 and 27 are face to face and diametrically opposite positions on the rod 12. The screws 26 and 27 are intended to hold in place by clamping. an object inserted in the hollow section of the rod 12 through the opening 16, for example the lower end of the pole of an umbrella.

Le dispositif de support 10 fonctionne comme suit : le bras 20 est d'abord pivoté en position opérationnelle. Par la suite, la pointe inférieure de la barre hélicoïdale 22 est appuyée contre le sol S. Le dispositif 10 est ensuite tourné autour de son axe de symétrie central à répétition. Chaque tour effectué par le dispositif 10 contribue à l'enfoncement de la barre hélicoïdale 22 et de la tige 12 dans le sol S, la barre hélicoïdale agissant comme un filet. Le dispositif de support 10 peut être enfoncé à une profondeur désirée; néanmoins, l'orifice intermédiaire 18 doit demeurer au dessus du sol S en tout temps.The support device 10 operates as follows: the arm 20 is first rotated to the operative position. Subsequently, the lower tip of the helical bar 22 is pressed against the ground S. The device 10 is then rotated about its central axis of symmetry repetition. Each turn made by the device 10 contributes to the depression of the helical bar 22 and the rod 12 in the soil S, the helical bar acting as a net. The support device 10 can be depressed to a desired depth; nevertheless, the intermediate orifice 18 must remain above the ground S at all times.

Au fur et à mesure que le dispositif s'enfonce dans le sol S, la matière granulaire composant le sol S va pénétrer à l'intérieur de la tige 12 par l'ouverture inférieure 14. Une colonne de terre se formera ainsi graduellement à l'intérieur de la tige 12. Cette colonne peut être plus ou moins difficile à déloger, selon la composition de la matière composant le sol S. La matière composant le sol S ne se faisant pas écarter, mais pénétrant à l'intérieur de la tige 12, le centre de gravité du dispositif 10 se trouve plus rabaissé, ce qui contribue à améliorer la solidité de la fixation au sol S du dispositif 10.As the device sinks into the ground S, the granular material composing the soil S will penetrate inside the rod 12 through the opening 14. A column of soil will thus gradually form inside the rod 12. This column may be more or less difficult to dislodge, depending on the composition of the material composing the soil S. The material composing the soil S does not not moving apart, but penetrating inside the rod 12, the center of gravity of the device 10 is further lowered, which contributes to improving the strength of the ground fixing S of the device 10.

Une fois le dispositif 10 enfoncé dans le sol S à la profondeur désirée, le bras 20 est basculé vers sa position repliée. Un objet, ayant un poteau de fixation, comme un parasol par exemple, peut ensuite être fixé temporairement ou de façon permanente au support. On continuera les explications en prenant l'exemple du parasol comme objet qui est fixé au-dessus du sol, quoique qu'il est entendu que tout objet pouvant être fixé à la tige 12 pourrait être utilisé avec le dispositif 10.Once the device 10 is pressed into the ground S at the desired depth, the arm 20 is tilted to its folded position. An object, having a mounting post, such as a sunshade for example, can then be temporarily or permanently attached to the support. Explanations will be continued by taking the example of the umbrella as an object which is fixed above the ground, although it is understood that any object that can be attached to the rod 12 could be used with the device 10.

L'extrémité inférieure du poteau de fixation de l'objet est inséré dans la tige 12 par l'ouverture supérieure 16, et est maintenu en place à l'aide des vis de serrage 26 et 27, qui, une fois vissées, exercent une pression suffisante sur le poteau de fixation de l'objet pour le garder fermement en place.The lower end of the object fixing post is inserted into the rod 12 through the upper opening 16, and is held in place by means of the clamping screws 26 and 27, which, once screwed in, exert an sufficient pressure on the object's attachment post to keep it firmly in place.

Pour ranger le dispositif 10, il suffit de suivre les étapes précédemment décrites dans l'ordre inverse.To store the device 10, simply follow the previously described steps in the reverse order.

La colonne de terre formée lors d'une précédente utilisation du dispositif 10 peut être demeurée au moins partiellement à l'intérieur du corps creux de la tige 12. Si le dispositif 10 est retiré et vissé de nouveau ultérieurement dans le sol S, d'autre terre viendra s'insérer dans la tige 12 par son extrémité inférieure 14. La colonne de terre sera donc de plus en plus haute dans la tige 12 jusqu'à ce qu'elle rejoigne le niveau de l'orifice intermédiaire 18. Le déflecteur 24 empêche l'écoulement de matière granulaire ascendant provenant du sol S plus loin que l'orifice intermédiaire 18 et évite ainsi l'obstruction de l'ouverture supérieure 16, ce qui permet l'insertion d'un objet dans l'ouverture 16. La colonne de terre est en effet graduellement déviée par le déflecteur 24 vers l'orifice 18 et évacuée de la tige 12 par l'orifice 18 au fur et à mesure que la nouvelle terre s'insère par l'extrémité inférieure 14.The earth column formed during a previous use of the device 10 may have remained at least partially inside the hollow body of the rod 12. If the device 10 is removed and screwed again later in the ground S, the another earth will be inserted into the rod 12 by its lower end 14. The earth column will therefore be higher and higher in the rod 12 until it reaches the level of the intermediate orifice 18. The deflector 24 prevents the flow of granular material ascending from the ground S further than the intermediate orifice 18 and thus avoids the obstruction of the upper opening 16, which allows the insertion of an object in the opening 16. The earth column is in effect gradually deflected by the deflector 24 to the orifice 18 and discharged from the rod 12 through the orifice 18 as the new earth is inserted through the lower end 14.

La barre hélicoïdale 22 peut être remplacée par un moyen alternatif d'ancrage. Selon une réalisation de l'invention, la barre hélicoïdale 22 est soudée sur la tige 12. Néanmoins, on aurait pu alternativement décider de ne pas inclure de barre hélicoïdale 22, l'enfoncement du dispositif 10 dans le sol S étant alors accompli en appliquant des coups de marteau ou de maillet sur l'extrémité supérieure de la tige 12.The helical bar 22 may be replaced by an alternative anchoring means. According to one embodiment of the invention, the helical bar 22 is welded to the rod 12. Nevertheless, it could alternatively be decided not to include a helical bar 22, the depression of the device 10 in the soil S being then accomplished by applying hammer or mallet strikes on the upper end of the rod 12.

Selon une réalisation de l'invention, le bras 20 pourrait ne pas être inclus sous la forme précédemment décrite. Un bras amovible, dont une extrémité serait insérée dans une douille située sur le flanc de la tige 12 lorsqu'on désire visser le dispositif 10 dans le sol S, par exemple, aurait pu être prévu. Alternativement, on aurait aussi pu pourvoir un dispositif de support 10 sans bras de vissage 20.According to one embodiment of the invention, the arm 20 could not be included in the form previously described. A removable arm, one end of which would be inserted in a socket located on the side of the rod 12 when it is desired to screw the device 10 into the ground S, for example, could have been provided. Alternatively, it would also be possible to provide a support device 10 without a screwing arm 20.

Les vis de serrage 26 et 27 peuvent être remplacées par des moyens alternatifs de fixation. Par exemple, un bouton poussoir aurait pu être placé dans la partie supérieure de la tige 12. La tige tubulaire de l'objet à supporter comprendrait alors des trous sur sa portion inférieure, un d'entre eux pouvant accueillir le bouton poussoir situé sur la tige 12, maintenant ainsi l'objet en place.The clamping screws 26 and 27 may be replaced by alternative fixing means. For example, a push button could have been placed in the upper part of the rod 12. The tubular rod of the object to be supported would then comprise holes on its lower portion, one of which could accommodate the push button located on the rod 12, keeping the object in place.

Toute autre modification à la présente invention qui ne dévie pas de la portée générale des revendications ci-annexées y est considérée incluse.Any other modification to the present invention which does not deviate from the general scope of the appended claims is considered included.
