Description

Procédé et dispositif mobile pour soulever et déplacer une charge posée sur une surface. Method and mobile device for lifting and moving a load placed on a surface.

La présente invention a pour objet un procédé et dispositif mobile pour soulever et déplacer une charge posée sur une surface.The present invention relates to a method and mobile device for lifting and moving a load placed on a surface.

Le secteur technique de l ' invention est le domaine de la fabrication et de l 'utilisation de dispositifs de levage mobiles pour déplacer des charges lourdes.The technical sector of the invention is the field of the manufacture and use of mobile lifting devices for moving heavy loads.

L' application principale de l ' invention est de soulever et déplacer un socle de type semelle en acier ou en béton posé sur le sol et à partir duquel un mât supportant lui-même à son autre extrémité tout type d' objet est maintenu ainsi verticalement sur le sol ; il peut s'agir par exemple de pieds de parasols, mais également de pieds de poteaux indicateurs, etc .. Dans de telles applications évoquées ci-dessus, lesdits socles ou plaques doivent être assez lourds pour d'une part, avec en plus des dimensions dans le plan du sol qui peuvent être assez importantes, offrir une bonne stabilité, d'autre part assurer une rigidité et une résistance à la flexion importante, et enfin pour toute application éviter que toute personne puisse les déplacer trop facilement ; de plus dans certaines utilisations où l ' on veut éviter que cela constitue un obstacle au déplacement sur le sol , que ce soit à pied ou avec des roues, l 'épai sseur de ces socles est assez faible et ne comporte aucune possibilité de prise latérale. II est donc très difficile de par le poids, les dimensions et l 'encombrement de telles charges, de les déplacer pour les amener d'un point de stockage à leur lieu d'utilisation ou simplement pour les écarter d' un lieu d'utilisation à un autre.The main application of the invention is to lift and move a plinth of steel or concrete sole type placed on the ground and from which a mast itself supporting at its other end any type of object is thus held vertically On the ground ; it may for example be the feet of umbrellas, but also the feet of sign posts, etc. In such applications mentioned above, said bases or plates must be heavy enough on the one hand, with in addition dimensions in the ground plane which can be quite large, offer good stability, on the other hand ensure rigidity and significant resistance to bending, and finally for any application avoid that any person can move them too easily; moreover in certain uses where one wishes to avoid that this constitutes an obstacle to movement on the ground, whether on foot or with wheels, the thickness of these bases is fairly low and does not include any possibility of lateral grip. . It is therefore very difficult, due to the weight, dimensions and size of such loads, to move them to bring them from a storage point to their place of use or simply to move them away from a place of use. to another.

Pour solutionner, en particulier le problème des parasols à socles en béton qui sont assez épais, on connaît un dispositif mobile à roues escamotables et non visibles, décrit dans la demande de brevet N ° FR 2.718.217 publiée le 6 octobre 1995, déposée sous le numéro 94/04269 par le même inventeur que la présente, soit Monsieur Jean- Pierre ANDREY, et délivrée au même titulaire que le présent déposant le 3 1 mai 1996.To solve, in particular the problem of umbrellas with concrete bases which are quite thick, there is known a mobile device with retractable wheels and not visible, described in patent application No. FR 2.718.217 published on October 6, 1995, filed under the number 94/04269 by the same inventor as the present one, namely Monsieur Jean- Pierre ANDREY, and issued to the same holder as the present applicant on May 31, 1996.

Un tel dispositif est en fait intégré à l 'intérieur du socle du parasol à déplacer et comprend un système mobile muni de roues escamotées en position repos et venant prendre appui sur le sol lorsque le système mobile est manoeuvré dans le but de déplacer ledit socle, grâce à un axe de pivotement solidaire de l 'armature de celui-ci ; ce système mobile comprend au moins deux roues dont chacune est en rotation libre autour d'un autre axe, un élément de levage situé à une extrémité de cette partie mobile et bloqué dans son déplacement vers le haut par un élément de retenue ou point d' appui de l ' armature du socle, et enfin un levier solidaire dudit système en un point situé à une position intermédiaire entre l 'axe de pivotement et l' extrémité de l 'élément de levage : ainsi , une fo rce exercée vers le bas sur le levier permet de soulever, par appui sous ledit élément de retenue, le socle et l a charge totale par rapport auxdites roues reposant su r le sol , de solidariser et de déplacer l 'ensemble vers un autre emplacement en faisant rouler les roues sur le sol .Such a device is in fact integrated inside the base of the parasol to be moved and comprises a mobile system provided with wheels retracted in the rest position and coming to bear on the ground when the mobile system is maneuvered in order to move said base, thanks to a pivot axis secured to the frame thereof; this mobile system comprises at least two wheels, each of which is in free rotation about another axis, a lifting element located at one end of this mobile part and blocked in its upward movement by a retaining element or point of support of the base frame, and finally a lever integral with said system at a point located at an intermediate position between the pivot axis and the end of the lifting element: thus, a force exerted downwards on the lever makes it possible to lift, by pressing under said retaining element, the base and the total load relative to said wheels resting on the ground, to secure and move the assembly to another location by rolling the wheels on the ground .

Un tel dispositif est ainsi assez bien adapté aux socles épais, tel qu 'en béton, de parasols, bien que la disposition des points d' appui et de rotation demandent un effort initial qui peut être assez important , et immobilisent dès son basculement la charge, qui est bloquée à la fois en appui directement sous son élément de retenue et par l ' axe de pivotement du dispositif mobile, ceci pouvant expliquer cela. Celui-ci est cependant très simple car il ne comporte pas de systèmes mécaniques complexes et articulés contrairement à d'autres brevets répondant au même obj ectif tels que celui N ° CH 682 975 qui comporte un mécanisme de type pignon crémaillère, difficile à diriger et assez encombrant. On connaît divers autres dispositifs permettant de soulever et de déplacer également des charges encombrantes ou lourdes grâce à des châssis disposant de bras basculants et de bras supports sur lesquels on pose en général la charge, tels que par exemple celui décrit à la demande N° FR 2.51 1.997 publiée le 4 mars 1983 pour la manutention de balles de paille. On connaît également pour soulever et déplacer les tampons d'égouts et autres grilles sans effort, d'une part la demande N ° FR 2.710.332 publiée le 31 mars 1995 qui décrit un châssis à quatre roues équipé d'un vérin avec une potence amovible ainsi qu'une chaîne réglable terminée par un crochet spécial sur lequel s'adapte une pièce de préhension et un timon ergonomique et démontable permetant de soulever ladite plaque ou tampon standard, et d' autre part la demande EP 254752 qui décrit deux éléments de levage situés chacun sur un bras solidaire d'un support de roue et relié à un levier apte à faire pivoter l 'ensemble autour de l 'axe des roues, les deux leviers étant solidarisés par une poignée commune, lesdits éléments de levage venant prendre la plaque d'égout à soulever par dessous grâce à des trous réalisés dans celle-ci. Ces dispositifs sont ainsi assez complexes comme dans le brevet suisse susmentionné.Such a device is thus fairly well suited to thick bases, such as concrete, of parasols, although the arrangement of the support and rotation points require an initial effort which can be quite significant, and immobilize the load as soon as it tips over. , which is blocked both by pressing directly under its retaining element and by the pivoting axis of the mobile device, this may explain this. This is however very simple because it does not include complex and articulated mechanical systems unlike other patents meeting the same objective such as that No. CH 682 975 which includes a rack and pinion type mechanism, difficult to steer and quite bulky. Various other devices are known which make it possible to also lift and move bulky or heavy loads thanks to chassis having tilting arms and support arms on which the load is generally placed, such as for example that described on request. N ° FR 2.51 1.997 published on March 4, 1983 for handling bales of straw. Also known for effortlessly lifting and moving sewer pads and other grids, on the one hand, application No. FR 2.710.332 published on March 31, 1995 which describes a four-wheel chassis equipped with a jack with a bracket removable as well as an adjustable chain terminated by a special hook on which a gripping piece and an ergonomic and dismountable drawbar are adapted, making it possible to lift said standard plate or buffer, and on the other hand application EP 254752 which describes two elements of lifting each located on an arm secured to a wheel support and connected to a lever capable of rotating the assembly around the axis of the wheels, the two levers being secured by a common handle, said lifting elements taking the manhole cover to be lifted from below thanks to holes made in it. These devices are thus quite complex as in the aforementioned Swiss patent.

Le problème posé est en effet de pouvoir soulever puis déplacer avec un seul dispositif une charge disposée sur le sol, qui peut être de toute épaisseur même faible, assez encombrante et lourde, sans moyens de manutention ni pièces mécaniques complexes, avec un minimum d'efforts et un basculement assurant une prise en charge progressive permettant à l ' opérateur un meilleur dosage de son effort, tout en contrôlant son levage et ledit basculement, et permettant d'assurer la stabilité de l 'ensemble une fois complètement soulevé du sol.The problem is to be able to lift and move with a single device a load placed on the ground, which can be of any thickness even small, quite bulky and heavy, without handling means or complex mechanical parts, with a minimum of efforts and a tilting ensuring a progressive assumption of responsibility allowing the operator a better dosage of his effort, while controlling its lifting and said tilting, and making it possible to ensure the stability of the whole once completely raised from the ground.

Le dispositif objet de la demande de brevet N ° WO 95/27169 précédemment déposée par Monsieur ANDREY, ne permet pas de résoudre entièrement ce problème puisque d'une part il prend appui sous une partie du socle pour le soulever (ceci n'est donc pas applicable pour une plaque en acier par exemple, posée sur le sol, même dans le cas d'une application à un pied de parasol) et d'autre part, comme indiqué précédemment, il immobilise directement en rotation le socle par rapport au dispositif mobile, augmentant alors en particulier les efforts de basculement. Une solution au problème posé est un procédé pour soulever et déplacer une charge dont la partie inférieure est posée sur une surface, à l ' aide d 'au moins un dispositif mobile, comprenant au moins un moyen d'appui pouvant se déplacer sur ladite surface et fixé à un châssis, au moins un bras support et au moins un levier de basculement faisant un angle α avec celui-ci, solidaires tous deux dudit châssis, lequel levier étant apte à faire pivoter l 'ensemble du dispositif autour d 'un axe par rapport audit moyen d' appui , afin de soulever ladite charge par le bras support ; suivant le procédé de l 'invention : - on dispose sur ladite charge au moins un point de levage pouvant coopérer avec au moins un élément de levage situé sur le bras suppo rt du dispositif mobile et situé au-dessus de la partie inférieure de la charge ,The device which is the subject of patent application No. WO 95/27169 previously filed by Mr. ANDREY, does not allow this problem to be entirely resolved since, on the one hand, it is supported under part of the base to lift it (this is therefore not not applicable for a steel plate for example, placed on the ground, even in the case of an application to a parasol base) and on the other hand, as indicated previously, it immobilizes the base directly in rotation relative to the device mobile, thus increasing in particular the tilting forces. A solution to the problem posed is a method for lifting and moving a load, the lower part of which is placed on a surface, using at least one mobile device, comprising at least one support means which can move on said surface. and fixed to a chassis, at least one support arm and at least one tilting lever making an angle α with the latter, both integral with said chassis, which lever being able to pivot the whole device around an axis relative to said support means, in order to lift said load by the support arm; according to the method of the invention: - there is on said load at least one lifting point capable of cooperating with at least one lifting element located on the suppo rt arm of the mobile device and located above the lower part of the load ,

- on positionne le ou les moyens d'appui du dispositif pour qu'ils soient en contact avec la surface quand on présente le dispositif manoeuvré par le levier pour que son élément de levage coopère avec le point de levage,- the support means or means of the device are positioned so that they are in contact with the surface when the device maneuvered by the lever is presented so that its lifting element cooperates with the lifting point,

- on abaisse alors ce levier, qui fait pivoter le dispositif autour de son axe, pour soulever au moins une partie de la charge par rapport à ladite surface, par son point de levage entraîné par l 'élément de levage,- this lever is then lowered, which rotates the device about its axis, to lift at least part of the load relative to said surface, by its lifting point driven by the lifting element,

- on continue à basculer le dispositif par ledit levier de telle sorte que ladite charge soit soulevée en pendule et articulée par rapport à cet élément de levage autour duquel elle peut pivoter.- We continue to tilt the device by said lever so that said load is raised in a pendulum and articulated relative to this lifting element around which it can pivot.

Dans un mode préférentiel de réalisation, quand ladite charge comporte un pied constitué par une plaque d'appui sur ladite surface, on réalise une découpe dans cette plaque suivant des dimensions au moins égales à celles de la projection, sur cette surface, de l'enveloppe externe de la partie inférieure du dispositif, comprenant au moins le ou les moyens d'appui, le ou les bras supports, la partie inférieure du châssis et l'extrémité du levier solidaire de celui-ci, et on dispose le au moins dit point de levage au bord de cette découpe ; on place le dispositif dans cette découpe et on relève la charge dont le pied entoure alors la partie inférieure du dispositif. Dans un autre mode de réalisation, quand il n 'est pas possible de découper ledit pied de la charge, on réalise un dispositif mobile comportant au moins deux points d 'appui disposés dans un plan passant par l 'axe de basculement, supportés par des bras latéraux et écartés d'une distance au moins égale à une des dimensions de la charge dans le plan de la surface et dont l'ensemble des autres éléments est situé à une hauteur par rapport à cette surface, au moins supérieure à celle de la partie inférieure de la charge au-dessus de laquelle on positionne le dispositif pour la soulever. Le dispositif permettant d' assurer le procédé de levage décrit ci- dessus, peut être amovible ou non par rapport à la charge à soulever, mais s 'articule dans tous les cas au-dessus de la partie inférieure de celle- ci quand il s'agit d 'un pied support d'une structure aérienne ou complètement au-dessus de la charge elle-même quand il s'agit de plaques seules.In a preferred embodiment, when said load comprises a foot constituted by a support plate on said surface, a cut is made in this plate according to dimensions at least equal to those of the projection, on this surface, of the outer casing of the lower part of the device, comprising at least the support means or means, the support arm (s), the lower part of the chassis and the end of the lever secured to it, and at least the following are available lifting point at the edge of this cut; the device is placed in this cutout and the load is raised, the foot of which then surrounds the lower part of the device. In another embodiment, when it is not possible to cut said foot from the load, a mobile device is produced comprising at least two support points arranged in a plane passing through the tilting axis, supported by lateral arms spaced apart by a distance at least equal to one of the dimensions of the load in the plane of the surface and the assembly of the other elements of which is situated at a height relative to this surface, at least greater than that of the lower part of the load above which the device is positioned to lift it. The device making it possible to carry out the lifting process described above, may or may not be removable with respect to the load to be lifted, but in any case is articulated above the lower part of the latter when it is 'acts of a support foot of an aerial structure or completely above the load itself when it is a question of plates alone.

Il y a deux possibilités de disposer le point de levage de la charge par rapport au centre de gravité de la partie inférieure de celle-ci ou de la charge elle-même, quand on utilise un seul dispositif mobile pour la soulever : - soit ledit point de levage est à la verticale de ce centre de gravité quand la charge est posée sur la surface et quand on soulève ladite charge, celle-ci est en pendule équilibrée sous le au moins élément de levage du dispositif suivant l ' invention ;There are two possibilities of placing the lifting point of the load in relation to the center of gravity of the lower part of the latter or of the load itself, when using a single mobile device to lift it: - either said lifting point is vertical to this center of gravity when the load is placed on the surface and when the said load is lifted, the latter is in a balanced pendulum under the at least lifting element of the device according to the invention;

- soit suivant un mode préférentiel de la présente invention, on dispose le au moins point de levage de la charge décalé latéralement en projection dans le plan de la surface par rapport au centre de gravité de la charge et on présente le dispositif du côté dit amont de celle-ci où est situé l 'élément de levage par rapport audit centre de gravité ; lorsqu 'on soulève alors ladite charge de la surface, son côté dit aval opposé au dispositif de levage s ' incline autour de son point de levage vers la surface et on continue le basculement du dispositif dans le sens de l' abaissement du levier provoquant l 'inclinaison de la charge dans l ' autre sens jusqu ' à ce qu 'au moins une butée du dispositif vienne en appui contre le côté amont de la charge et l'immobilise alors dans une position relative ; on peut basculer ensuite l'ensemble ainsi constitué jusqu 'à tout angle voulu par rapport à la surface sur laquelle on peut alors le déplacer. Suivant un mode particulier de réalisation, dans le cas où la charge à soulever est une plaque ou autre objet plat ayant un poids de l 'ordre de 150 à 240 kilos et/ou une surface trop importante pour être soulevé par un seul dispositif mobile, on peut disposer sur ladite charge au moins deux points de levage répartis à la périphérie de celle-ci et on présente au moins deux dispositifs suivant l'invention, chacun à un desdits points de levage et on soulève la charge en basculant les deux dispositifs par leur levier respectif.- Either according to a preferred embodiment of the present invention, there is at least the load lifting point offset laterally in projection in the plane of the surface relative to the center of gravity of the load and the device is presented on the so-called upstream side from this where the lifting element is located with respect to said center of gravity; when this load is then lifted from the surface, its so-called downstream side opposite the lifting device tilts around its lifting point towards the surface and the device continues to tilt in the direction of lowering of the lever causing the tilt the load in the other direction until at least one stop of the device comes in pressing against the upstream side of the load and then immobilizes it in a relative position; the assembly thus formed can then be tilted up to any desired angle with respect to the surface on which it can then be moved. According to a particular embodiment, in the case where the load to be lifted is a plate or other flat object having a weight of the order of 150 to 240 kilos and / or an area too large to be lifted by a single mobile device, at least two lifting points can be placed on said load distributed around the periphery thereof and at least two devices according to the invention are presented, each at one of said lifting points and the load is raised by tilting the two devices by their respective leverage.

On peut également utiliser le procédé et le dispositif de la présente invention suivant un mode de réalisation permettant de soulever le même type de socles que ceux décrits dans la demande de brevet précédente FR 2718217 du même inventeur : le dispositif peut alors être aussi intégré dans le socle assez épais tel qu'en béton, mais avec des dispositions de points d'appui et de rotation différentes qui lui donnent donc une meilleure mise en oeuvre grâce aux caractéristiques de la présente invention et tel que décrit dans les figures 10 à 12 ci- jointes.One can also use the method and the device of the present invention according to an embodiment making it possible to lift the same type of bases as those described in the previous patent application FR 2718217 by the same inventor: the device can then also be integrated into the fairly thick base such as concrete, but with different support and rotation points arrangements which therefore give it a better implementation thanks to the characteristics of the present invention and as described in FIGS. 10 to 12 below attached.

Le résultat est de nouveaux procédés et dispositifs de levage et de déplacement d'une charge posée sur une surface à l'aide d'un dispositif mobile répondant au problème posé et sans avoir les inconvénients des dispositifs connus à ce jour.The result is new methods and devices for lifting and moving a load placed on a surface using a mobile device responding to the problem posed and without having the drawbacks of the devices known to date.

En effet, le procédé de levage suivant l'invention est très simple puisqu'il utilise l'effet multiplicateur connu des bras de levier, grâce à un bras de levage plus court que celui de basculement sur lequel l' opérateur appuiera pour soulever la charge, même plus lourde que lui, suivant un principe donc parfaitement connu et un procédé ne nécessitant aucun dispositif complexe.Indeed, the lifting method according to the invention is very simple since it uses the known multiplier effect of the lever arms, thanks to a lifting arm shorter than that of tilting on which the operator will press to lift the load. , even heavier than it, according to a principle therefore perfectly known and a process requiring no complex device.

Pour assurer un levage dans de bonnes conditions, puis la stabilité de la charge qui, dans les applications principales de l'invention, est assez encombrante et lourde, on soulève d ' abord un côté de celle-ci en la basculant par appui de son autre côté maintenu contre le sol , puis la totalité de sa partie inférieure la plus lourde ; on la maintient alors suspendue en pendule assez proche du sol, en l 'immobilisant grâce à une butée du dispositif si nécessaire ; en particulier, cette butée est d 'autant plus nécessaire quand on utilise un seul dispositif et en fonction du décalage du point de levage par rapport au centre de gravité de la charge, ce qui bien sûr entraîne ledit basculement de l 'ensemble de celle-ci , mais qui est donc contrôlé comme indiqué précédemment et explicité ci-après.To ensure lifting under good conditions, then the stability of the load which, in the main applications of the invention, is quite bulky and heavy, first one side is lifted by tilting it by pressing its other side held against the ground, then all of its heaviest lower part; it is then kept suspended in a pendulum fairly close to the ground, immobilizing it by means of a stop of the device if necessary; in particular, this stop is all the more necessary when using a single device and depending on the offset of the lifting point relative to the center of gravity of the load, which of course causes said tilting of the whole of this below, but which is therefore checked as indicated above and explained below.

La simplicité extrême d'un tel dispositif permet une fabrication à coût réduit et le procédé de levage en lui-même permet même d ' adapter un dispositif suivant l'invention à toute charge existante qui dispose déjà d'un point de levage proche de leur centre de gravité ou sur laquelle il peut être facilement rajouté ; pour des applications particulières telles que les pieds de parasol en forme de plaque métallique, ceux-ci peuvent être adaptés en réalisant une découpe telle qu 'indiquée précédemment et décrite ci-après .The extreme simplicity of such a device allows manufacturing at reduced cost and the lifting process itself even allows a device according to the invention to be adapted to any existing load which already has a lifting point close to their center of gravity or on which it can be easily added; for particular applications such as the parasol feet in the form of a metal plate, these can be adapted by making a cut as indicated above and described below.

On pourrait citer d ' autres avantages de la présente invent ion, mais ceux cités ci-dessus en montrent déjà suffisamment pou r en prouver la nouveauté et l 'intérêt .One could cite other advantages of the present invention, but those mentioned above already show it sufficiently to prove its novelty and interest.

La description et les figures ci-après représentent des exemples de réalisation de l 'invention, mais n 'ont aucun caractère limitatif : d'autres réalisations sont possibles, dans le cadre de la portée et de l'étendue de cette invention, en particulier en changeant la disposition des roues par rapport au bras de levier et au bras de levage, ainsi qu'avec ou sans butée ; de même, il est possible de remplacer les roues par tout type de moyen d'appui, tel que par exemple des patins avec des spatules inclinées à l ' avant et à l'arrière pour des déplacements sur le sable ou la neige ou autre surface.The description and the figures below represent exemplary embodiments of the invention, but are in no way limiting: other embodiments are possible, within the scope and scope of this invention, in particular by changing the arrangement of the wheels with respect to the lever arm and the lifting arm, as well as with or without a stop; similarly, it is possible to replace the wheels with any type of support means, such as for example skates with spatulas inclined at the front and at the rear for movement on sand or snow or other surface .

In a known manner, as in the previous patent of

Monsieur ANDREY cité en introduction , le dispositif mobile 3 suivant l ' invention pour soulever et déplacer une charge 15 posée sur une surface 1 1 , comprend au moins un moyen d'appui 4 , qui est ici représenté par deux roues mais une seule pourrait suffi re ou sous forme d'un rouleau , sur ladite surface 1 1 et porté chacun par un bras supportMr. ANDREY cited in the introduction, the mobile device 3 according to the invention for lifting and moving a load 15 placed on a surface 11, comprises at least one support means 4, which is here represented by two wheels but only one could suffice re or in the form of a roll, on said surface 1 1 and each carried by a support arm

16 et un châssis 13 , au moins un bras support 6 fixé au châssis 13 , 16, au moins un levier de basculement 5 solidaire également du châssis 13 , 16 et dont l'extrémité inférieure au moins forme un angle α donné avec ledit bras 6 , lequel levier 5 permettant de faire pivoter le dispositif 3 autour d'un axe 9 par rapport audit moyen d' appui 4.16 and a chassis 13, at least one support arm 6 fixed to the chassis 13, 16, at least one tilting lever 5 also integral with the chassis 13, 16 and the lower end of which at least forms a given angle α with said arm 6 , which lever 5 making it possible to pivot the device 3 about an axis 9 relative to said support means 4.

Le dispositif mobile 3 comporte en outre au moins un élément de levage 7 situé sur le bras suppo rt 6 tel qu' à une de ses extrémités, comme représenté sur les figures j ointes, lequel élément de levage est un moyen de suspension de ladite charge 15, pendue à celui-ci par son point de levage 12 situé au-dessus de sa partie inférieure 1 ; surtout suivant le mode préférentiel de réalisation suivant l'invention, quand ledit élément de levage 7 devant coopérer avec ce point de levage 12 de la charge 15 n'est pas à la verticale du centre de gravité C de celle-ci mais décalé par rapport à celui-ci, et qu'on utilise qu'un seul dispositif suivant l'invention pour la même charge, le dispositif comporte au moins une butée 8 située en arrière dudit élément de levage 7 du même côté par rapport à celui-ci que l'axe 9 de pivotement du dispositif. Sur l'ensemble des figures 1 à 9 ci-jointes, il est représenté une charge 15 constituée essentiellement d'un pied support 1 constitué d'une tôle épaisse mais qui pourrait être toute armature ou cadre, posé sur un sol 1 1 horizontal et sur lequel est fixé verticalement un tube 2 pouvant être un support de mât tel que pour un parasol, mais également pour des panneaux de signalisation par exemple.The mobile device 3 further comprises at least one lifting element 7 located on the suppo rt arm 6 such that at one of its ends, as shown in the appended figures, which lifting element is a means for suspending said load 15, hanging from the latter by its lifting point 12 situated above its lower part 1; especially according to the preferred embodiment according to the invention, when said lifting element 7 having to cooperate with this lifting point 12 of the load 15 is not vertical to the center of gravity C thereof but offset from to it, and that only one device according to the invention is used for the same load, the device comprises at least one stop 8 situated behind said lifting element 7 on the same side with respect to it as the pivot axis 9 of the device. In all of Figures 1 to 9 attached, there is shown a load 15 consisting essentially of a support leg 1 consisting of a thick sheet but which could be any frame or frame, placed on a floor 1 1 horizontal and on which is fixed vertically a tube 2 which can be a mast support such as for a parasol, but also for traffic signs for example.

Si le centre de gravité G de la partie inférieure 1 ou pied de l 'ensemble est toujours situé sous le point de levage 12, le centre de gravité C de l'ensemble de la charge avec son parasol par exemple, peut être situé au-dessus de l 'élément de levage 12 mais dans tous les cas, durant l'opération de levage et de déplacement, l'ensemble de la charge sera en suspension et soulevé en pendule par son point de levage 12.If the center of gravity G of the lower part 1 or foot of the assembly is always located under the lifting point 12, the center of gravity C of the entire load with its parasol for example, can be located above above the lifting element 12 but in all cases, during the lifting and displacement operation, the entire load will be suspended and lifted in pendulum by its lifting point 12.

Dans les figures 1 à 6, ledit pied support 1 à soulever, comporte une découpe 10 dans laquelle le dispositif de levage est amené en le soulevant car il peut être assez léger comme sur la figure 1 ou par roulement depuis la surface du sol 1 1 sur ledit pied support dont l 'épaisseur est relativement faible, jusqu'à ce que les moyens d'appui 4 tels que les roues soient à nouveau en contact, à travers la découpe 10, avec la surface 1 1.In Figures 1 to 6, said support foot 1 to be lifted, comprises a cutout 10 in which the lifting device is brought up by lifting it because it can be quite light as in Figure 1 or by rolling from the ground surface 1 1 on said support leg whose thickness is relatively small, until the support means 4 such as the wheels are again in contact, through the cutout 10, with the surface 11.

Dans les exemples de représentation des figures 7 à 9 , ledit pied support 1 ne comporte pas de découpe et le dispositif mobile 3 a alors nécessairement deux points d'appui 4 disposés dans un plan passant par l' axe 9 de basculement supporté par des bras latéraux 16 et écartés d'une distance au moins égale à une des dimensions de la charge 15, de préférence la plus petite, telle que dans le sens de la largeur pour un rectangle, tel que représenté sur la figure 7, dans le plan de la surface 1 1 ; l 'ensemble des autres éléments du dispositif mobile est situé à une hauteur par rapport à cette surface au moi ns supérieure à celle de la partie inférieure 1 de ladite charge 15 au-dessus de laquelle on positionne le dispositif 3 pour la soulever.In the examples of representation of FIGS. 7 to 9, said support foot 1 does not include a cutout and the mobile device 3 then necessarily has two support points 4 arranged in a plane passing through the tilting axis 9 supported by arms side 16 and separated by a distance at least equal to one of the dimensions of the load 15, preferably the smallest, such as in the width direction for a rectangle, as shown in Figure 7, in the plane of the surface 1 1; all of the other elements of the mobile device are situated at a height relative to this surface at least greater than that of the lower part 1 of said load 15 above which the device 3 is positioned to lift it.

Dans les exemples de réalisation des figures 1 à 4, la butée 8 est située et reliée à l ' autre extrémité du ou des bras supports 6, par rapport à l'élément de levage 7, et qui sont aussi ceux 16 des moyens d 'appui 4, de telle sorte que ledit axe 9 de pivotement est situé à une position intermédiai re entre les plans de projection de l 'élément de levage 7 de la butée 8 suivant l 'angle α formé par lesdits bras supports 6, 16 avec ledit levier de basculement 5 , sur un axe dont la direction est celle desdits bras supports 6, 16. En fait, ladite butée 8 peut être portée directement par le levier de basculement 5. Celui-ci peut être constitué de deux parties, dont l 'une peut être un manchon femelle par exemple, et solidaire du châssis du dispositif et l ' autre un manche 5 t mâle am ovible dont une extrémité peut se loger dans ladite partie femelle 5 et l ' autre être coudée pour faciliter une prise manuelle. Le châssis 13 , 16 du dispositif est constitué dans tous les exemples ci-j oints par :In the exemplary embodiments of FIGS. 1 to 4, the stop 8 is located and connected to the other end of the support arm or arms 6, relative to the lifting element 7, which are also those 16 of the means of support 4, so that said pivot axis 9 is located at an intermediate position between the projection planes of the lifting element 7 of the stop 8 at the angle α formed by said support arms 6, 16 with said tilting lever 5, on an axis whose direction is that of said support arms 6, 16. In fact, said stopper 8 can be carried directly by the tilting lever 5. This can consist of two parts, the one may be a female sleeve for example, and integral with the chassis of the device and the other a 5 t male handle with a removable end, one end of which can be housed in said female part 5 and the other can be bent to facilitate manual gripping. The chassis 13, 16 of the device is constituted in all the examples attached by:

- les bras 16 supports des roues 4, qui , même si une seule peut suffire pour des charges relativement légères, sont préférentiellement deux montés libres suivant un axe de rotation XX ' au moins parallèle si ce n'est confondu avec l'axe 9 de basculement du dispositif,the arms 16 supporting the wheels 4, which, even if only one may suffice for relatively light loads, are preferably two free mounted along an axis of rotation XX 'at least parallel if not confused with the axis 9 of device tilting,

- une traverse de liaison 13 desdits bras supports 16 de roues,- a cross member 13 of said wheel support arms 16,

- des supports 14 éventuels de butées 8 tels que sur les figures 5, 6,- supports 14, if any, of stops 8 such as in FIGS. 5, 6,

- et un bras au moins de levage 6, tel que représenté sur les figures 7 à 9, ou éventuellement deux bras de levage si deux éléments de levage sont nécessaires, tels que sur les figures 1 à 4 et en ce cas, lesdits bras de levage 6 peuvent être les mêmes bras que les supports 16 de roues.- And at least one lifting arm 6, as shown in FIGS. 7 to 9, or possibly two lifting arms if two lifting elements are necessary, such as in FIGS. 1 to 4 and in this case, said lifting arms lifting 6 can be the same arms as the wheel supports 16.

Quand on veut en effet avoir une bonne stabilité latérale de la charge une fois soulevée et pendue par son point de levage 12, ledit dispositif peut comporter deux éléments de levage 7 écartés l 'un de l 'autre et situés suivant un même axe YY' parallèle à l ' axe 9 de pivotement, tel que représenté sur les figures 1 à 4.When it is indeed desired to have good lateral stability of the load once lifted and hung by its lifting point 12, said device may include two lifting elements 7 spaced from one another and situated along the same axis YY 'parallel to the pivot axis 9, as shown in FIGS. 1 to 4.

Si on ne met qu'un seul élément de levage 7, il est préférable alors que le dispositif comporte deux butées 8 écartées l 'une de l 'autre ou une seule mais de portée assez large et situées suivant un même axe ZZ ' parallèle à l ' axe 9 de pivotement tel que représenté sur les figures 5 à 6 ; dans ce cas, lesdites butées 8 j , 82 sont portées par des supports 14 placés à l 'autre extrémité des bras supports de roues 16, à l 'opposé de l 'extrémité supportant la traverse de liaison 13 portant elle-même en son milieu l 'élément de levage 7.If only one lifting element 7 is put, it is preferable then that the device comprises two stops 8 spaced from one another or only one but of fairly wide range and located along the same axis ZZ 'parallel to the pivot axis 9 as shown in Figures 5 to 6; in this case, said stops 8 d, 8 2 are carried by supports 14 placed at the other end of the wheel support arms 16, opposite the end supporting the cross member 13 carrying itself in its middle of lifting element 7.

Dans l ' ensemble des figures, il est représenté un seul levier de basculement 5 solidaire de la traverse 13 de liaison et situé en son milieu entre les bras supports 16 des roues 4 , mais il pourrait être double, par exemple dans le prolongement des bras supports 16 :In all of the figures, there is shown a single tilting lever 5 secured to the cross member 13 of connection and located in its middle between the support arms 16 of the wheels 4, but it could be double, for example in the extension of the arms supports 16:

- dans les figures 1 à 4, ledit levier et la traverse de liaison 13 sont situés vers l ' autre extrémité du ou des bras supports 6, 16 par rapport à celle où est situé l'élément de levage 7 et supporte di rectement la butée 8 ; - dans l 'exemple de réalisation des figures 5 et 6, ledit levier de basculement 5, la traverse 13 et l'élément de levage 7 sont situés du même côté que le ou les bras supports 6, 16 par rapport à l' axe de pivotement 9 , et même vers la même extrémité du ou des bras supports 6, 16 ; - dans l 'exemple des figures 7 à 9 , les bras supports de roues 16 étant situés latéralement bien entendu par rapport à la plaque à soulever 1 , sont indépendants du bras de levage 6 qui peut être unique et situé alors de préférence dans l 'axe du dispositif, peut donc être dans le prolongement du manche 5 de basculement ; c'est alors l 'ensemble de la traverse 13 et dudit bras de levage 6 qui font office directement de butée au pied support 1 à soulever situé en dessous.- In Figures 1 to 4, said lever and the cross member 13 are located towards the other end of the support arm (s) 6, 16 relative to that where the lifting element 7 is located and directly supports the stop 8; - In the embodiment of Figures 5 and 6, said tilting lever 5, the cross member 13 and the lifting element 7 are located on the same side as the support arm or arms 6, 16 relative to the axis of pivoting 9, and even towards the same end of the support arm or arms 6, 16; - In the example of FIGS. 7 to 9, the wheel support arms 16 being located laterally of course relative to the plate to be lifted 1, are independent of the lifting arm 6 which can be unique and then preferably located in the axis of the device, can therefore be in the extension of the tilting handle 5; it is then the assembly of the cross member 13 and of said lifting arm 6 which act directly as a stop for the support leg 1 to be lifted situated below.

L'élément de levage 7 du dispositif suivant l 'invention et le point de levage 12 solidaire de la charge 15 à soulever, doivent bien sûr coopérer entre eux pour assurer un bon accrochage, tels que respectivement un anneau ou un axe pour l 'un et une potence ou un crochet pour l'autre, comme représenté sur les figures 1 à 4, nécessitant alors de basculer le dispositif pour glisser l'élément de levage par dessous ledit point de levage 12 et l'y engager ; dans la représentation des figures 7 à 9 où le mouvement de basculement relatif entre le dispositif 3 et la plaque 1 est très limité, ils peuvent coopérer par engagement de l'élément de levage 7 que l 'on glisse horizontalement par exemple dans un anneau constituant le point de levage 12 ; d'autres combinaisons de moyens de levage peuvent être bien sûr utilisés.The lifting element 7 of the device according to the invention and the lifting point 12 secured to the load 15 to be lifted, must of course cooperate with each other to ensure good attachment, such as respectively a ring or an axis for one and a bracket or a hook for the other, as shown in Figures 1 to 4, then requiring to tilt the device to slide the lifting element from below said lifting point 12 and engaging it; in the representation of FIGS. 7 to 9 where the relative tilting movement between the device 3 and the plate 1 is very limited, they can cooperate by engagement of the lifting element 7 which is slid horizontally for example in a constituent ring the lifting point 12; other combinations of lifting means can of course be used.

De même, si de préférence, comme représenté dans lesdites figures, les deux moyens d'appui 4 sont des roues montées libres en rotation autour dudit axe XX' de pivotement 9, d'autres moyens d'appui 4 peuvent être utilisés tels que des patins. Suivant l 'ensemble des représentations des figures 1 à 9 ci-jointes, mais particulièrement représenté dans les différentes séquences suivant les figures 1 à 4 :Similarly, if preferably, as shown in said figures, the two support means 4 are wheels mounted free in rotation about said pivot axis XX '9, other support means 4 can be used such as skates. According to all the representations of Figures 1 to 9 attached, but particularly shown in the different sequences according to Figures 1 to 4:

- on dispose le au moins point de levage 12 de la charge 15 décalé latéralement en projection dans le plan de la surface 1 1 par rapport au centre de gravité C de la charge 15 et on présente le dispositif 3 du côté dit amont 152 de la charge 15 où est situé l 'élément de levage 12 par rapport audit centre de gravité C,- there is at least lifting point 12 of the load 15 laterally offset in projection in the plane of the surface 1 1 relative to the center of gravity C of the load 15 and the device 3 is presented on the so-called upstream side 15 2 of the load 15 where the lifting element 12 is located with respect to said center of gravity C,

- lorsqu'on commence à soulever ladite charge 15 de la surface 1 1 , son côté dit aval 15 j opposé au dispositif de levage 3 s'incline autour de son point de levage 12 vers la surface 1 1 contre laquelle son bord latéral l t correspondant reste en appui : le levier 5 étant alors assez vertical suivant un angle δ de plus de 45° par exemple par rapport au sol, son basculement ne nécessite qu'un effort réduit puisque le dispositif 3 ne soulève alors qu'une partie de la charge ; on peut ainsi continuer sans trop d' efforts le basculement du dispositif 3 dans le sens de l'abaissement du levier 5 provoquant l'inclinaison de la charge dans l'autre sens jusqu'à ce qu'au moins une butée 8 du dispositif 3 vienne en appui contre le côté amont 152 de la charge 15 : on peut alors soulever complètement celle-ci assez facilement car le levier 5 pouvant faire dans cette position un angle δ de moins de 45 ° avec la surface 1 1 , l ' opérateur peut y transférer plus facilement tout son poids sans avoir à fai re un effort musculaire trop important ; - on immobilise alors la charge sur le dispositif mobile 3 dans une position relative, et on peut basculer l 'ensemble ainsi constitué jusqu'à tout angle β voulu par rapport à la surface 1 1 sur laquelle on peut alors le déplacer.- when starting to lift said load 15 from the surface 1 1, its so-called downstream side 15 j opposite the lifting device 3 tilts around its lifting point 12 towards the surface 1 1 against which its lateral edge l t corresponding remains in support: the lever 5 then being fairly vertical at an angle δ of more than 45 ° for example relative to the ground, its tilting requires only a reduced effort since the device 3 then lifts only part of the charge ; one can thus continue without too much effort the tilting of the device 3 in the direction of lowering of the lever 5 causing the inclination of the load in the other direction until at least one stop 8 of the device 3 come to bear against the upstream side 15 2 of the load 15: we can then lift completely this one quite easily because the lever 5 being able to make in this position an angle δ of less than 45 ° with the surface 1 1, the operator can more easily transfer all its weight there without having to make too much muscular effort ; - The load is then immobilized on the mobile device 3 in a relative position, and the assembly thus formed can be tilted to any desired angle β relative to the surface 11 on which it can then be moved.

Dans la représentation des figures 10 à 12, un autre exemple de dispositif selon l ' invention est représenté schématiquement en position de repos sur la figure 10, et en position de déplacement sur la figure 1 1 .In the representation of FIGS. 10 to 12, another example of a device according to the invention is shown diagrammatically in the rest position in FIG. 10, and in the displacement position in FIG. 11.

La charge 15 à déplacer est ici un socle assez épais tel que celui d ' un mât de parasol 2 et qui peut être réalisé soit en béton soit en matière plastique rigide remplie ensuite de sable ou d' eau, sa surface inférieure 1 ou semelle reposant sur le sol 1 1. Le dispositif mobile 3 peut alors être incorporé dans l ' épaisseur dudit socle 15 : il s ' escamote dans un logement 17 prévu pour cela dans celui-ci, et s ' articule autour d 'un axe 7 , 12 qui le rend solidaire dudit socle 15 et qui constitue à la fois l ' élément 7 et le point de levage 12 suivant l ' invention. Tous les autres éléments du dispositif tel que représenté en perspective sur la figure 12 ont les mêmes caractéristiques et fonctions que ceux décrits précédemment dans les figures précédentes sur lesquels nous ne reviendrons donc pas. La particularité nouvelle de ce mode de réalisation est la disposition relative de ces divers éléments, en effet : le levier de basculement 5 est situé vers une extrémité du bras support 6, l ' axe 9 de pivotement qui est également celui du support de roue 4 est situé vers l ' autre extrémité du bras support 6, et l 'élément de levage 7 , qui est en même temps l' axe d ' articulation rendant solidaire le dispositif avec le socle 15 , est positionné entre les deux ; le levier de basculement 5, dont une partie 5 t fait un angle α avec le bras support 6 et une autre partie 52 forme la poignée, comporte dans sa partie pénétrant dans le socle 15 la butée 8 : après basculement réciproque dudit levier 5 vers le bas, et du socle 15 vers le haut, par rotation autour du bord 1 ] de son côté aval et simultanément par décollement du bord opposé 12 de son côté amont (comme dans les exemples de réalisation précédents, du fait du décalage obligatoire dans le mode de réalisation de ses figures 10 à 12 du centre de gravité du socle 15 par rapport à l ' axe 7 de levage) , ladite butée 8 vient ainsi prendre appui contre la surface 10 j d'un côté, de forme adaptée pour recevoir ladite butée 8, de l 'orifice au travers duquel passe l 'embase dudit levier 5. The load 15 to be moved here is a fairly thick base such as that of a parasol mast 2 and which can be made either of concrete or of rigid plastic then filled with sand or water, its lower surface 1 or sole resting on the ground 1 1. The mobile device 3 can then be incorporated into the thickness of said base 15: it retracts into a housing 17 provided for this in it, and is articulated around an axis 7, 12 which makes it integral with said base 15 and which constitutes both the element 7 and the lifting point 12 according to the invention. All the other elements of the device as shown in perspective in FIG. 12 have the same characteristics and functions as those described previously in the previous figures, to which we will therefore not return. The new feature of this embodiment is the relative arrangement of these various elements, in fact: the tilting lever 5 is located towards one end of the support arm 6, the pivot axis 9 which is also that of the wheel support 4 is located towards the other end of the support arm 6, and the lifting element 7, which is at the same time the hinge pin making the device integral with the base 15, is positioned between the two; the tilting lever 5, part 5 t of which forms an angle α with the support arm 6 and another part 5 2 forms the handle, comprises in its part penetrating into the base 15 the stop 8: after reciprocal tilting of said lever 5 towards bottom, and from base 15 upwards, by rotation around edge 1 ] on its downstream side and simultaneously by detaching from the opposite edge 1 2 on its upstream side (as in the previous embodiments, due to the compulsory offset in the embodiment of its figures 10 to 12 from the center of gravity of the base 15 relative to the lifting axis 7), said stop 8 thus comes to bear against the surface 10 j on one side, of a shape adapted to receive said stop 8, of the orifice through which the base of said lever 5.
