Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

La présente invention concerne une table élévatrice pour véhicules, et plus particulièrement une table du type comportant une plate-forme horizontale de support reposant sur un ensemble de levage, ladite plate-forme étant équipée d'organes positionnables d'ancrage destinés à coopérer avec une partie inférieure de véhicule afin de brider ledit véhicule sur la table élévatrice.The present invention relates to a lifting table for vehicles, and more particularly a table of the type comprising a horizontal support platform resting on a lifting assembly, said platform being equipped positionable anchors intended to cooperate with a lower part of the vehicle in order to clamp said vehicle on the lifting table.

ARRIERE PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION

On connaít déjà de nombreuses tables élévatrices pour véhicules du type précité, en particulier dans le cadre des bancs de redressement de véhicules accidentés. L'ensemble de levage utilisé est en général du type comportant des bielles en ciseaux permettant de conserver l'horizontalité de la plate-forme de support quelle que soit la hauteur de celle-ci, depuis la position la plus basse pour charger le véhicule, jusqu'à la position la plus haute de travail, en passant par les positions intermédiaires.We already know many lifting tables for vehicles of the aforementioned type, in particular in the frame of righting benches for damaged vehicles. The lifting assembly used is generally of the type comprising scissor rods for keeping the horizontality of the support platform whatever or the height thereof, from the most low to load the vehicle, to the lowest position working high, going through the positions intermediate.

Le document FR-A-2 581 634 de la demanderesse décrit par exemple une table élévatrice associée à un marbre de redressement, avec des plaques montées de façon amovible sur le cadre. Lorsque le véhicule a été mis en place, il est soulevé par rapport au marbre, ce qui permet de démonter les plaques et de fixer les pinces destinées à fixer le véhicule par le bas de caisse, après quoi le véhicule est abaissé pour venir en appui sur les pinces, lesquelles sont alors bloquées.Document FR-A-2 581 634 by the applicant describes for example a lifting table associated with a straightening marble, with plates mounted so removable on the frame. When the vehicle has been put in square, it is raised relative to the marble, allowing disassemble the plates and fix the clamps intended for fix the vehicle by the underbody, after which the vehicle is lowered to rest on the clamps, which are then blocked.

Le document US-A-2002/144623 décrit par ailleurs des supports servant à déplacer un véhicule reposant par des roues sur un élévateur. Chaque support est constitué par deux bras associés à des blocs respectifs qui peuvent être éloignés ou rapprochés l'un de l'autre par un système de vérin, chaque bras étant monté pour pivoter dans un plan horizontal entre une position active de support où ils sont parallèles, et une position escamotée où ils sont dans le prolongement l'un de l'autre. Un tel agencement est de structure compliquée et a priori insuffisamment robuste.Document US-A-2002/144623 also describes supports for moving a vehicle resting by wheels on an elevator. Each support is made up by two arms associated with respective blocks which can be distant or close to each other by a system cylinder, each arm being mounted to pivot in a plane horizontal between an active support position where they are parallel, and a retracted position where they are in the extension of each other. Such an arrangement is complicated structure and a priori insufficiently robust.

On pourra aussi se référer pour l'arrière-plan technologique aux documents US-A-5 967 494, US-A-4 916 933, US-A-4 862 727, FR-A-2 158 577, FR-A-2 752 538 et FR-A-2 687 335.We can also refer to the background technological documents US-A-5,967,494, US-A-4,916,933, US-A-4 862 727, FR-A-2 158 577, FR-A-2 752 538 and FR-A-2 687 335.

On connaít également des mécanismes de commande électroniques adaptés à la commande d'une plate-forme élévatrice à système de levage en ciseaux, comme enseigné dans le document US-A-5 695 173.We also know control mechanisms electronic devices suitable for controlling a platform scissor lift system, as taught in document US-A-5,695,173.

Dans le cas particulier des véhicules accidentés, on doit lever le véhicule mis en place sur la plate-forme horizontale de support afin d'effectuer certaines opérations de mesure et/ou de redressement sur les parties tordues ou accidentées, en général à l'aide de moyens mécaniques tel que potence de traction etc..., de façon bien connue. On parle alors en général de bancs de redressement ou marbres.In the particular case of damaged vehicles, we must lift the vehicle placed on the platform horizontal support in order to perform certain measurement and / or rectification operations on the parts twisted or damaged, usually by means mechanical, such as a pulling crane, etc. known. We generally speak of righting benches or marbles.

D'une façon générale, une fois que le véhicule est mis en place sur la plate-forme horizontale de support dans la position la plus basse de celle-ci, on met en place les organes positionnables d'ancrage, en général au nombre de quatre, afin que chacun d'eux enserre une partie inférieure du châssis du véhicule, en général une lèvre s'étendant dans un plan vertical. Une fois les organes d'ancrage mis en place aux quatre coins souhaités, lesquels coins sont situés au voisinage immédiat des points de levage du véhicule définis par le constructeur, on procède au bridage du véhicule, puis au levage de celui-ci par ses points d'ancrage.Generally speaking, once the vehicle is set up on the horizontal support platform in the lowest position of this one, we set up the positionable anchors, generally number of four, so that each of them encloses a lower part of the vehicle chassis, usually a lip extending in a vertical plane. Once the anchors are in place in place at the four desired corners, which corners are located in the immediate vicinity of the lifting points of the vehicle defined by the manufacturer, we proceed with the clamping of the vehicle, then lifting it by its points anchor.

Ainsi, conformément à une technique constante, on choisit des points d'ancrage voisins des points de levage imposés avant de lever le véhicule par lesdits points d'ancrage. Cette approche a toujours été conservée dans l'optique de disposer d'un accès optimal aux roues de la partie accidentée du véhicule, en général les roues avant. En effet, il est nécessaire en général de démonter une ou deux roues pour mieux accéder aux parties du châssis à redresser.So, according to a constant technique, we chooses anchor points close to lifting points imposed before lifting the vehicle by said points anchor. This approach has always been retained in the optics of having optimal access to the wheels of the damaged part of the vehicle, usually the front wheels. Indeed, it is generally necessary to disassemble one or two wheels for better access to parts of the chassis straighten.

Une telle technique est toutefois contraignante dans la mesure où l'on doit nécessairement utiliser des points d'ancrage voisins des points de levage qui sont définis par le constructeur du véhicule, ces derniers points étant bien entendu situés à des distances relatives différentes selon le type de véhicule, ce qui oblige à des réglages constants lorsque l'on passe d'un véhicule à l'autre.Such a technique is however binding insofar as one must necessarily use anchor points adjacent to the lifting points which are defined by the vehicle manufacturer, these points being of course located at relative distances different depending on the type of vehicle, which requires constant settings when moving from vehicle to the other.

De plus, la technique précitée présente l'inconvénient d'utiliser les points d'ancrage comme points de levage, de sorte que toute vibration de la table lors de son élévation ou de son abaissement est directement transmise au châssis du véhicule.In addition, the above technique presents the downside of using anchor points as points lifting, so that any vibration of the table when its raising or lowering is directly transmitted to the vehicle chassis.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

L'invention a pour objet de concevoir une table élévatrice pour véhicules plus performante que les tables existantes rappelées ci-dessus, et en particulier plus facilement adaptable à des types différents de véhicules sur lesquels des opérations de redressement et/ou de mesure doivent être effectuées.The object of the invention is to design a table vehicle lift more efficient than tables existing mentioned above, and in particular more easily adaptable to different types of vehicles on which recovery and / or measurement operations must be performed.

Ce sont ces deux bras indépendants qui assurent ainsi le support de la zone concernée du véhicule par l'intermédiaire de la roue de celui-ci.This problem is solved in accordance with the invention thanks to a lifting table with a platform horizontal support resting on a lifting assembly, said platform being equipped with positionable members anchor intended to cooperate with a lower part of the vehicle to restrain said vehicle on the table lift, said lift table being remarkable in that that the platform is further equipped with side supports on which the vehicle wheels can position to lift said vehicle by its wheels without use the anchors, at least one of these support elements being of variable geometry between a active support configuration in which the wheel concerned is based on its support element, and a passive release configuration in which the wheel concerned is released from its support element and can be dismantled or reassembled, said vehicle then being restrained by the anchoring members, said support element to variable geometry including a shoe connecting to the periphery of the platform, and two independent arms cantilevered on the shoe to pivot around of a respective essentially vertical axis while remaining in a common horizontal plane. These are the two arms independent who thus provide support for the area concerned of the vehicle through the wheel of this one.

Ainsi, la table élévatrice du type précité permet de lever le véhicule par ses roues, ce qui présente l'avantage considérable de libérer des zones constructives du châssis. De plus, le support par les roues du véhicule n'est pas incompatible avec le démontage d'une ou deux roues dans la mesure où l'on utilise justement à cet effet des éléments de support à géométrie variable, le bridage du véhicule étant effectué lorsque la hauteur désirée de la plate-forme horizontale de support est atteinte. D'ailleurs, ceci permet aux opérateurs de travailler plus confortablement dans la mesure où les organes positionnables d'ancrage sont mis en place lorsque le véhicule a été levé.Thus, the lifting table of the aforementioned type allows to lift the vehicle by its wheels, which presents the considerable advantage of freeing up constructive areas of the chassis. In addition, the support by the vehicle wheels is not incompatible with the dismantling of one or two wheels insofar as one uses precisely for this purpose support elements with variable geometry, the clamping of the vehicle being operated when the desired height of the horizontal support platform is reached. Besides, this allows operators to work more comfortably as far as the organs positionable anchors are put in place when the vehicle has been lifted.

De préférence, le sabot de l'élément de support à géométrie variable est agencé pour s'accrocher directement et de façon libérable sur une glissière latérale de la plate-forme, laquelle glissière sert également à l'accrochage des organes positionnables d'ancrage. Ainsi, il suffit de positionner préalablement les éléments de support sur les deux glissières latérales de la plate-forme en tenant compte du dimensionnement du véhicule. On est alors assuré d'un centrage correct de chaque roue sur la partie de support qui lui est associée.Preferably, the shoe of the support member to variable geometry is arranged to hang directly and releasably on a side slide of the platform, which slide also serves to the attachment of positionable anchoring members. So, it suffices to position the elements of support on the two side rails of the platform taking into account the sizing of the vehicle. We are then assured of correct centering of each wheel on the support part associated with it.

En particulier, on pourra prévoir que la glissière latérale est constituée par une lèvre continue, et que le sabot est équipé, comme les organes d'ancrage, de crochets passant sur cette lèvre continue, avec possibilité de coulisser sur ladite lèvre continue en l'absence de charge. Les éléments de support à géométrie variable ainsi que les organes d'ancrage sont alors positionnés comme des curseurs sur la lèvre continue de chaque côté de la plate-forme horizontale, la position choisie restant stable jusqu'à ce qu'une charge soit exercée.In particular, provision may be made for the slide lateral is formed by a continuous lip, and that the shoe is equipped, like the anchors, with hooks passing over this continuous lip, with the possibility of slide on said continuous lip in the absence of load. Support elements with variable geometry as well as anchors are then positioned as sliders on the continuous lip on each side of the platform horizontal, the chosen position remains stable until that a charge be exercised.

De préférence encore, les deux bras indépendants de l'élément de support à géométrie variable sont articulés sur le sabot entre une position rapprochée où ils sont sensiblement parallèles, correspondant à la configuration active de l'élément de support, et une position écartée où ils forment un angle ouvert, correspondant à la configuration passive dudit élément de support.More preferably, the two independent arms of the variable geometry support element are articulated on the hoof between a close position where they are substantially parallel, corresponding to the configuration support element, and a spaced position where they form an open angle, corresponding to the passive configuration of said support element.

En particulier, l'élément de support à géométrie variable est équipé d'un organe de verrouillage agencé pour verrouiller de façon libérable les deux bras indépendants lorsque ceux-ci sont en position rapprochée. Par exemple, l'organe de verrouillage sera agencé sous la forme d'un levier monté pour pivoter par une extrémité autour de l'un des deux bras indépendants, l'autre extrémité dudit levier présentant une encoche destinée à coopérer avec l'autre bras en position rapprochée desdits bras. Il est alors aisé pour l'opérateur de manipuler le levier afin de verrouiller ou de déverrouiller les deux bras concernés de l'élément de support à géométrie variable.In particular, the geometry support element variable is equipped with a locking member arranged to releasably lock the two independent arms when these are in the close position. For example, the locking member will be arranged in the form of a lever mounted to pivot at one end around one two independent arms, the other end of said lever having a notch intended to cooperate with the other arms in position close to said arms. It is then easy for the operator to manipulate the lever in order to lock or unlock the two arms concerned from the element of support with variable geometry.

De préférence encore, les deux bras indépendants de l'élément de support à géométrie variable sont de structure tubulaire, de préférence non tournante autour de leur axe central. En particulier, les deux bras indépendants sont équipés d'allonges télescopiques logées dans lesdits bras en position rentrée, lesdites allonges pouvant être tirées pour faciliter le rapprochement desdits bras en présence d'une roue remise en place. En effet, grâce à ces allonges, il est aisé de développer un couple important de fermeture de l'angle en agissant sur l'extrémité des allonges, afin de revenir dans la position de support dans laquelle le verrouillage peut être réalisé.More preferably, the two independent arms of the variable geometry support element are of structural tubular, preferably not rotating around their axis central. In particular, the two independent arms are fitted with telescopic extensions housed in said arms in the retracted position, said extensions being able to be pulled to facilitate the bringing together of said arms in the presence a wheel replaced. Indeed, thanks to these extensions, it is easy to develop a significant closing torque of the angle by acting on the end of the extensions, so to return to the support position in which the locking can be achieved.

De préférence enfin, la table élévatrice est équipée, à l'avant ou l'arrière de la plate-forme de support, et de chaque côté de ladite plate-forme, d'un élément de support à géométrie variable, les deux autres éléments de support étant de simples berceaux ou plans accrochés sur ladite plate-forme. En effet, on aura en général besoin de démonter une ou deux roues avant ou arrière du véhicule accidenté, auquel cas on peut se contenter d'un support de type traditionnel pour les deux autres roues.Preferably finally, the lifting table is equipped, at the front or rear of the platform support, and on each side of said platform, of a support element with variable geometry, the other two support elements being simple cradles or planes hung on said platform. Indeed, we will have general need to disassemble one or two front wheels or rear of the damaged vehicle, in which case it is possible content with a traditional type of support for both other wheels.

D'autres caractéristiques et avantages de l'invention apparaítront plus clairement à la lumière de la description qui va suivre, concernant un mode d'exécution particulier, en référence aux figures des dessins annexés.Other features and benefits of the invention will appear more clearly in the light of the description which follows, concerning an embodiment particular, with reference to the figures of the accompanying drawings.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

On va tout d'abord décrire la structure générale d'une table élévatrice conformément à l'invention en se référant aux figures 1 et 2.We will first describe the general structure of a lifting table according to the invention by referring to Figures 1 and 2.

On distingue sur ces figures une table élévatrice T pour véhicules, qui est du type comportant une plate-forme horizontale de support 10 reposant sur un ensemble de levage 20.We distinguish in these figures a lifting table T for vehicles, which is of the type comprising a platform horizontal support 10 resting on a set of lifting 20.

La plate-forme horizontale de support 10 est constituée de composants rigides permettant de garantir le caractère indéformable de son plan. On distingue en l'espèce deux longerons parallèles 11 réunis par des traverses 12, 13, 14. On a également illustré ici une potence de traction équipant la plate-forme horizontale de support 10: on distingue en effet une potence de type traditionnel 1, qui est montée par sa poutrelle 2 sur la traverse avant 13 de la plate-forme horizontale 10, avec une poutre 3 crantée qui permet l'accrochage de chaínes de traction, un vérin de manoeuvre d'inclinaison 4, et un ensemble de roulement 5 pour le déplacement de la potence sur le sol.The horizontal support platform 10 is made up of rigid components to guarantee the undeformable character of his plan. We distinguish in the species two parallel spars 11 joined by sleepers 12, 13, 14. Also illustrated here is a traction crane fitted to the horizontal platform support 10: there is indeed a type of gallows traditional 1, which is mounted by its beam 2 on the front cross member 13 of the horizontal platform 10, with a notched beam 3 which allows the attachment of chains of traction, a tilt actuator 4, and a bearing set 5 for moving the stem On the ground.

L'ensemble de levage 20 est également de type traditionnel. On distingue deux paires de bielles 21, 22 articulées en 24 pour former un ensemble en ciseaux. Les bielles 22 sont articulées inférieurement sur une platine de support 23 reposant sur le sol, tandis que leur extrémité supérieure se raccorde à une traverse articulée au niveau de galets en 26 sur une glissière 27 équipant chacun des longerons 11. Les autres bielles 21 sont de la même façon articulées en 25 sur la plate-forme de support 10, tandis que leurs extrémités inférieures passent dans des glissières horizontales associées. Le mécanisme en ciseaux garantit la parfaite horizontalité de la plate-forme de support 10, et ce quelle que soit la hauteur de celle-ci par rapport à la platine 23. Le levage est commandé par un ou deux vérins hydrauliques 28 qui sont articulés entre la platine de base 23 et une traverse reliant ici les bielles 21. On a également prévu un vérin pneumatique d'aide au démarrage 29 : en effet, lors du début de l'élévation de la plate-forme de support, après chargement sur celle-ci d'un véhicule, les vérins 28 ont des difficultés à exercer le couple nécessaire pour amorcer le levage de la table, de sorte que le vérin de démarrage 29 à faible course verticale permet d'apporter un effort d'appoint jusqu'à ce que les ciseaux fassent un angle suffisant, après quoi les seuls vérins 28 entrent en action pour terminer le levage de la table. Ce principe d'assistance au démarrage est bien connu, et l'on pourra se référer à ce titre au document US-A-2 931 519.The lifting assembly 20 is also of the type traditional. There are two pairs of connecting rods 21, 22 articulated at 24 to form a set of scissors. The connecting rods 22 are articulated lower on a plate support 23 resting on the ground, while their upper end connects to an articulated cross member at the level of rollers at 26 on a slide 27 fitted each of the side members 11. The other connecting rods 21 are of the same way articulated in 25 on the support platform 10, while their lower ends pass in associated horizontal slides. The mechanism in scissors guarantee the perfect horizontality of the platform support 10, regardless of the height of this with respect to the plate 23. The lifting is controlled by one or two hydraulic cylinders 28 which are articulated between base plate 23 and a crosspiece connecting here the connecting rods 21. A cylinder is also provided starting aid tire 29: in fact, when start of the elevation of the support platform, after loading onto it of a vehicle, the jacks 28 have difficulty exercising the torque necessary to initiate lifting the table, so that the starting cylinder 29 with a small vertical stroke makes it possible to bring an effort until the scissors make an angle sufficient, after which the only cylinders 28 come into action to finish lifting the table. This principle starting assistance is well known, and we can refer to this title in document US-A-2 931 519.

La plate-forme 10 est en outre équipée d'organes positonnables d'ancrage 30 et d'éléments de support latéraux 40, 50. Les figures 1 et 2 montrent un seul des quatre organes d'ancrage 30, et des éléments de support latéraux 40, 50 d'un seul côté de la plate-forme horizontale de support, étant entendu que l'on prévoira en général des éléments de support latéraux identiques de l'autre côté, pour respecter la symétrie.The platform 10 is further equipped with organs 30 anchorable and support elements side 40, 50. Figures 1 and 2 show only one of the four anchoring members 30, and support elements side 40, 50 on one side of the platform horizontal support, it being understood that in general identical side support elements of the other side, to respect the symmetry.

On retrouve ces éléments sur la vue de la figure 3, qui permet de distinguer un organe positionnable d'ancrage 30, un élément de support latéral 40 qui est du type à géométrie variable comme cela va être expliqué ci-après, et un élément de support latéral 50 qui est quant à lui de type traditionnel.We find these elements in the view of Figure 3, which makes it possible to distinguish a positionable anchoring member 30, a lateral support element 40 which is of the type variable geometry as will be explained below, and a lateral support element 50 which is in turn traditional type.

La structure des composants 40, 30, et 50 sera mieux comprise en se référant aux vues en perspective éclatée respectivement des figures 4, 5, et 6.The structure of components 40, 30, and 50 will be better understood by referring to perspective views exploded respectively in Figures 4, 5, and 6.

Comme cela est mieux visible sur la figure 4, l'élément de support à géométrie variable 40, sur lequel une roue du véhicule peut se positionner pour lever ledit véhicule par ses quatre roues sans utiliser les organes d'ancrage 30, comporte un sabot 41 de liaison à la périphérie de la plate-forme 10, et deux bras indépendants 43, 44 montés en porte-à-faux sur le sabot 41 pour pivoter autour d'un axe respectif essentiellement vertical noté Z tout en restant dans un plan horizontal commun. En l'espèce, le sabot 41 de l'élément de support à géométrie variable 40 présente deux crochets 42 permettant un accrochage direct sur la glissière latérale 15 de la plate-forme 10, laquelle glissière 15 sert également à l'accrochage des organes positionnables d'ancrage 30 et des autres éléments de support latéraux de type traditionnel 50. Comme cela est visible ici, la glissière latérale 15 est constituée par une lèvre rectiligne continue, s'étendant dans un plan vertical, et le sabot 41 est équipé, tout comme les organes d'ancrage 30, de crochets passant sur cette lèvre continue, avec possibilité de coulisser librement sur ladite lèvre en l'absence de charge. Le sabot 41 avec ses deux crochets 42 peut ainsi être positionné facilement et avec précision en n'importe quel emplacement de la glissière 15, avant de disposer le véhicule de telle façon que l'élément de support à géométrie variable 40 soit exactement à l'aplomb de l'essieu de la roue concernée.As is best seen in Figure 4, the variable geometry support element 40, on which a vehicle wheel can be positioned to lift said vehicle by its four wheels without using the organs anchor 30, comprises a shoe 41 for connection to the periphery of platform 10, and two independent arms 43, 44 mounted cantilever on the shoe 41 to pivot around a respective essentially vertical axis denoted Z while remaining in a common horizontal plane. In the case, the shoe 41 of the geometry support element variable 40 has two hooks 42 allowing a direct hooking on the side slide 15 of the platform 10, which slide 15 also serves to the attachment of positionable anchoring members 30 and other traditional side support elements 50. As can be seen here, the lateral slide 15 consists of a continuous rectilinear lip, extending in a vertical plane, and the shoe 41 is fitted, like the anchors 30, with hooks passing over this continuous lip, with the possibility of slide freely on said lip in the absence of charge. The shoe 41 with its two hooks 42 can thus be easily and precisely positioned anywhere which location of the slide 15, before placing the vehicle in such a way that the support member to variable geometry 40 be exactly in line with the axle of the wheel concerned.

Chaque bras indépendant 43, 44 présente un appendice arrière 43.1, 44.1 qui est reçu entre deux oreilles 43.2, 44.2 du sabot 41, l'axe Z étant matérialisé par des tourillons 43.3, 44.3 avec un blocage en place au moyen de goupilles 43.4, 44.4. Chaque bras 43, 44 peut ainsi librement pivoter autour de l'axe Z concerné. Les deux bras 43, 44 peuvent plus précisément pivoter entre une position rapprochée où ils sont sensiblement parallèles, correspondant à la configuration active de l'élément de support 40, et une position écartée où ils forment un angle ouvert, correspondant à la configuration passive dudit élément de support 40.Each independent arm 43, 44 has a rear appendage 43.1, 44.1 which is received between two ears 43.2, 44.2 of shoe 41, the Z axis being materialized by pins 43.3, 44.3 with a blocking in place at means of pins 43.4, 44.4. Each arm 43, 44 can thus freely rotate around the Z axis concerned. The two arms 43, 44 can more precisely pivot between a close position where they are substantially parallel, corresponding to the active configuration of the element support 40, and an open position where they form an angle open, corresponding to the passive configuration of said support element 40.

Ainsi, l'élément de support à géométrie variable 40 est déformable entre deux configurations, dont une première configuration qui est une configuration active de support, dans laquelle la roue concernée repose sur son élément de support, et une deuxième configuration, qui est une configuration passive de libération dans laquelle la roue concernée est libérée de son élément de support et peut alors être donc démontée ou remontée.Thus, the variable geometry support element 40 is deformable between two configurations, a first of which configuration which is an active support configuration, in which the wheel concerned rests on its support, and a second configuration, which is a passive release configuration in which the wheel concerned is released from its support element and can then be dismantled or reassembled.

Les deux bras indépendants 43, 44 de l'élément de support à géométrie variable 40 sont ici de structure tubulaire. De préférence, cette structure est prévue non tournante autour de leur axe central Y, afin d'éviter un patinage lors de la mise en place du véhicule au sol sur ses supports en position basse de la table. Les éléments tubulaires formant les bras indépendants 43, 44 logent en outre des allonges télescopiques 45, 46. Ces allonges 45, 46 comportent un manchon arrière 45.1, 46.1 coulissant télescopiquement dans les bras 43, 44, avec une goupille de sécurité qui empêche une extraction intempestive desdites allonges, et leur autre extrémité passe dans des embouts 43.5, 44.5 qui sont sertis en extrémité des bras 43, 44. Ces extrémités des allonges 45, 46 sont de préférence équipées de poignées 45.2, 46.2 facilitant la manoeuvre de resserrement des bras lorsque les allonges 45, 46 sont sorties. Ainsi, ces allonges télescopiques 45, 46 sont logées dans les bras en position rentrée, et peuvent être tirées pour faciliter le rapprochement des bras en présence d'une roue remise en place.The two independent arms 43, 44 of the element of support with variable geometry 40 are here of structure tubular. Preferably, this structure is provided not rotating around their central axis Y, in order to avoid a skating when placing the vehicle on the ground on its supports in the low position of the table. The elements tubular forming the independent arms 43, 44 are housed in in addition to telescopic extensions 45, 46. These extensions 45, 46 have a rear sleeve 45.1, 46.1 sliding telescopically in the arms 43, 44, with a pin security that prevents untimely extraction of said extensions, and their other end goes through end caps 43.5, 44.5 which are crimped at the end of the arms 43, 44. These ends of the extensions 45, 46 are preferably equipped with handles 45.2, 46.2 facilitating the operation of tightening of the arms when the extensions 45, 46 are exits. Thus, these telescopic extensions 45, 46 are housed in the arms in the retracted position, and can be drawn to facilitate the bringing together of the arms in the presence a wheel replaced.

Lorsqu'une roue repose sur les deux bras 43, 44, avec son essieu qui est sensiblement dans le plan vertical médian de l'ensemble à géométrie variable 40, la charge exercée tend à écarter l'un de l'autre les deux bras indépendants 43, 44. A cet effet, il est prévu un organe de verrouillage agencé pour verrouiller de façon libérable les deux bras indépendants 43, 44 lorsque ceux-ci sont en position rapprochée. En l'espèce, on a prévu un organe de verrouillage agencé sous la forme d'un levier 47 qui est monté pour pivoter par une extrémité en 48 sur l'embout 43.5 associé au bras 43, l'autre extrémité dudit levier présentant une encoche 49 qui est destinée à coopérer avec l'autre embout 44.5 associé à l'autre bras 44. Il suffit donc à l'opérateur de faire pivoter le levier 47 pour passer d'une position verrouillée à une position libérée, et inversement dans l'autre sens. Bien entendu, l'opérateur ne libérera le verrouillage qu'en l'absence de charge verticale exercée sur l'élément de support à géométrie variable 40. When a wheel rests on the two arms 43, 44, with its axle which is substantially in the vertical plane median of the variable geometry assembly 40, the load exercised tends to separate the two arms from each other 43, 44. For this purpose, a locking device arranged to releasably lock the two independent arms 43, 44 when these are in close position. In the present case, a lock arranged in the form of a lever 47 which is mounted to pivot at one end at 48 on the end piece 43.5 associated with arm 43, the other end of said lever having a notch 49 which is intended to cooperate with the other end piece 44.5 associated with the other arm 44. It suffices so the operator can rotate the lever 47 to move from a locked position to a released position, and vice versa in the other direction. Of course, the operator will only release the lock if there is no charge vertical exerted on the geometry support element variable 40.

Il sera en général prévu un autre élément de support à géométrie variable 40 symétrique de celui qui est représenté par rapport au plan vertical médian de la table élévatrice.In general, another element of support with variable geometry 40 symmetrical to that which is represented in relation to the median vertical plane of the table lift.

La figure 5 permet de mieux comprendre la structure des organes positionnables d'ancrage 30 qui sont destinés à coopérer avec une partie inférieure de véhicule, telle qu'une lèvre verticale, afin de brider ledit véhicule sur la table élévatrice.Figure 5 provides a better understanding of the structure positionable anchoring members 30 which are intended for cooperate with a lower part of the vehicle, such as a vertical lip, in order to clamp said vehicle on the lifting table.

L'organe d'ancrage 30 comprend une double membrure 31 se terminant par un sabot commun d'accrochage 32 qui permet un accrochage direct et libérable sur la lèvre continue 15 de la même façon que les crochets 42 pour l'ensemble de support latéral 40 précité. Lorsque l'organe 30 est en place sur la lèvre continue 15, un levier inférieur articulé 33 forme l'autre partie de la pince verrouillant l'organe d'ancrage 30 sur la plate-forme horizontale 10 pour éviter tout risque de dégagement intempestif par soulèvement. Le blocage dans la direction longitudinale des longerons est assuré par une clavette 35 passant dans une fente associée 34, et qui vient assurer un coincement d'ensemble dans la position longitudinale choisie.The anchoring member 30 comprises a double frame 31 ending with a common attachment shoe 32 which allows direct and releasable attachment to the lip continues 15 in the same way as hooks 42 for the aforementioned lateral support assembly 40. When the organ 30 is in place on the continuous lip 15, a lever articulated lower 33 forms the other part of the clamp locking the anchoring member 30 on the platform horizontal 10 to avoid any risk of release untimely lifting. Blocking in the direction longitudinal of the side members is provided by a key 35 passing through an associated slot 34, and which provides a overall jamming in the longitudinal position chosen.

Le réglage est bien entendu également prévu à la fois en hauteur et dans la direction transversale. Pour la hauteur, on utilise deux supports 36.1, 36.2 de part et d'autre de la double membrure 31, lesquels supports sont traversés par une tige filetée 36 qui est maintenue en place par des écrous 36.3, 36.4. La direction de la double membrure 31 assure un réglage dans une direction parallèle à la direction Y précitée, c'est-à-dire perpendiculaire à la direction longitudinale de la table. Le réglage en hauteur est assuré par les écrous associés à la tige filetée 36, laquelle tige filetée est surmontée de deux mors de serrage 37.1, 37.2 qui forment une pince 37. En l'espèce, on a prévu une pince de bridage 37 à deux mors 37.1, 37.2 qui viennent enserrer une lèvre inférieure L du châssis du véhicule comme cela est mieux visible sur le détail de la figure 8. Une garniture 37.4 est prévue sur la partie 37.1 de la pince, et un ressort intermédiaire 37.5 tend à écarter l'un de l'autre les deux mors de ladite pince. Les deux mors 37.1, 37.2 sont par ailleurs réunis par un ensemble de boulonnage 37.3 agencé dans une direction transversale. Ainsi, les deux mors de la pince 37 peuvent être amenés dans la position exactement désirée selon les trois axes de coordonnées orthogonaux.The adjustment is of course also provided for in the both in height and in the transverse direction. For the height, we use two supports 36.1, 36.2 on each side and other of the double frame 31, which supports are crossed by a threaded rod 36 which is held in place with nuts 36.3, 36.4. The direction of the double member 31 provides adjustment in a parallel direction to the aforementioned direction Y, that is to say perpendicular to the longitudinal direction of the table. The setting in height is ensured by the nuts associated with the rod threaded 36, which threaded rod is surmounted by two clamping jaws 37.1, 37.2 which form a clamp 37. In in this case, a two-jaw clamping clamp 37 is provided 37.1, 37.2 which enclose a lower lip L of the vehicle chassis as this is best seen on the detail of figure 8. A gasket 37.4 is provided on the part 37.1 of the clamp, and an intermediate spring 37.5 tends to separate the two jaws of said one from the other clamp. The two jaws 37.1, 37.2 are also joined together by a bolt assembly 37.3 arranged in a transverse direction. Thus, the two jaws of the clamp 37 can be brought to exactly the desired position along the three orthogonal coordinate axes.

La plate-forme de support 10 sera ainsi équipée de quatre organes d'ancrage 30 tels que précédemment décrit.The support platform 10 will thus be equipped with four anchoring members 30 as previously described.

La figure 6 permet de distinguer un élément de support 50 qui est de type traditionnel sous la forme d'un simple berceau ou plan. En l'espèce, l'organe de support 50 comporte un châssis 51 surmonté d'une plaque principale de support 54, ledit châssis étant relié à la plate-forme horizontale de support 10 d'une part par un tronçon de longeron 52 reçu de façon télescopique dans le longeron 11 de ladite plate-forme, et d'autre part au moyen d'un accrochage par un crochet 53 sur la lèvre continue 15 de la même façon que les équipements 30, 40 précédemment décrits. Un tel agencement permet de régler aisément la position longitudinale de l'ensemble de support 50 par rapport à la structure de la plate-forme de support 10. On a ici prévu un élément de support de type télescopique, comportant une deuxième partie avec une traverse 55 portant deux plates-formes de support 57, ladite traverse étant accrochée par un crochet 56 sur la même lèvre continue 15 de la plate-forme 10, l'ensemble passant en coulissant par des fentes associées 58 ménagées sous la plaque de support 54. Il est aisé de comprendre qu'il suffit de tirer la partie complémentaire à la façon d'un tiroir pour augmenter la surface horizontale de support. Figure 6 makes it possible to distinguish an element of support 50 which is of the traditional type in the form of a simple cradle or plane. In this case, the support member 50 comprises a frame 51 surmounted by a main plate of support 54, said chassis being connected to the platform horizontal support 10 on the one hand by a section of spar 52 received telescopically in the spar 11 of said platform, and on the other hand by means of a hooking by a hook 53 on the continuous lip 15 of the same as the equipment 30, 40 previously described. Such an arrangement allows the position to be easily adjusted longitudinal of the support assembly 50 relative to the support platform structure 10. We have here provided a telescopic type support element, comprising a second part with a cross member 55 carrying two platforms support 57, said cross member being hooked by a hook 56 on the same continuous lip 15 of the platform 10, the assembly passing by sliding through slots associated 58 formed under the support plate 54. It is easy to understand that it is enough to draw the part complementary to the way of a drawer to increase the horizontal support surface.

Le mode opératoire de la table élévatrice qui vient d'être décrite en détail sera mieux compris en se référant aux figures 7, 9, 10.The operating mode of the lifting table that comes to be described in detail will be better understood by referring in Figures 7, 9, 10.

Lorsque la table élévatrice est en position très basse, c'est-à-dire que la plate-forme horizontale de support 10 est voisine du sol, on positionne les éléments de supports latéraux 40, 50 sur leur glissière latérale 15 au niveau des positions désirées qui correspondent au dimensionnement du véhicule V concerné. Ensuite, le véhicule est amené sur la table élévatrice de telle façon que ses roues soient exactement centrées sur chacun des éléments de support latéraux 40, 50. On procède ensuite au levage de la table au moyen des vérins 28 aidés au départ par le vérin de démarrage 29. Le véhicule V est ainsi levé par ses quatre roues, contrairement aux procédures traditionnelles qui prévoient d'abord de brider le véhicule sur la plate-forme et ensuite de lever ledit véhicule par ses points d'ancrage. Au contraire ici, la table élévatrice de l'invention permet de positionner les organes d'ancrage 30 lorsque le véhicule a déjà été levé, ce qui procure un confort et une précision très supérieurs. Chacun des quatre organes d'ancrage est alors mis en place dans la bonne position, et les pinces 37 associées viennent enserrer une partie inférieure du véhicule, en l'espèce une lèvre L comme cela est mieux visible sur le détail de la figure 8.When the lifting table is in the very position low, that is to say that the horizontal platform of support 10 is close to the ground, we position the elements lateral supports 40, 50 on their lateral slide 15 at the desired positions which correspond to the dimensioning of the vehicle V concerned. Then the vehicle is brought to the lifting table in such a way its wheels are exactly centered on each of the lateral support elements 40, 50. Next, lifting the table by means of jacks 28 assisted at the start by the starting cylinder 29. The vehicle V is thus lifted by its four wheels, contrary to procedures traditional plans to first restrain the vehicle on the platform and then to lift said vehicle by its anchor points. On the contrary here, the lifting table of the invention makes it possible to position the anchoring members 30 when the vehicle has already been lifted, which provides a much higher comfort and precision. Each of the four anchors is then put in place in the correct position, and the associated clamps 37 enclose a lower part of the vehicle, in this case a lip L as is better visible in the detail in Figure 8.

La situation correspond alors à la position illustrée sur la figure 7, qui montre le véhicule V sur sa table T en position haute, porté par ses roues R au niveau des éléments de support latéraux 40, 50, en étant également bridé par les organes d'ancrage 30.The situation then corresponds to the position illustrated in Figure 7, which shows vehicle V on its table T in high position, carried by its wheels R at level lateral support elements 40, 50, also being clamped by the anchoring members 30.

Si l'on veut maintenant enlever une roue avant, il convient d'intervenir sur l'élément de support à géométrie variable 40 concerné. La procédure est illustrée schématiquement sur la figure 9 :

  • - a) le véhicule repose par ses quatre roues R sur les éléments de support latéraux 40, 50 et l'opérateur a bridé le véhicule V par les quatre organes d'ancrage 30 ;
  • - b) l'opérateur a agi sur le levier 47 pour déverrouiller les bras indépendants 43, 44 de l'élément de support à géométrie variable 40 concerné, comme cela est illustré par la flèche ;
  • - c) les deux bras 43, 44 peuvent alors être écartés l'un de l'autre en quittant leur position parallèle, comme illustré par les flèches, pour atteindre une position à angle ouvert qui sera dans la pratique un angle obtus proche de l'angle plat (en fait, la suspension de la roue du véhicule exercera déjà un effort tendant à écarter naturellement l'un de l'autre les deux bras 43, 44, de sorte qu'il suffit pour l'opérateur d'écarter les bras suffisamment pour avoir un accès complet à la roue R) ;
  • - d) la roue R a été enlevée, ce qui libère l'accès à la zone concernée du châssis du véhicule ;
  • - e) on peut si on le souhaite procéder à l'enlèvement de l'élément de support à géométrie variable 40 comme schématisé par la flèche afin d'éviter toute interférence des bras 43, 44, ou toute gêne pour l'opérateur devant intervenir devant cette zone du châssis.
    • If you now want to remove a front wheel, you should work on the variable geometry support element 40 concerned. The procedure is illustrated schematically in Figure 9:
  • - a) the vehicle rests by its four wheels R on the lateral support elements 40, 50 and the operator has clamped the vehicle V by the four anchoring members 30;
  • - b) the operator acted on the lever 47 to unlock the independent arms 43, 44 of the variable geometry support element 40 concerned, as illustrated by the arrow;
  • - c) the two arms 43, 44 can then be separated from each other by leaving their parallel position, as illustrated by the arrows, to reach an open angle position which will in practice be an obtuse angle close to l 'flat angle (in fact, the suspension of the vehicle wheel will already exert a force tending to naturally separate the two arms 43, 44 from each other, so that it suffices for the operator to separate the arm enough to have full access to the wheel R);
  • - d) the wheel R has been removed, which frees access to the area concerned from the chassis of the vehicle;
  • - e) it is possible, if desired, to remove the support element with variable geometry 40 as shown diagrammatically by the arrow in order to avoid any interference of the arms 43, 44, or any discomfort for the operator having to intervene in front of this area of the chassis.

    • Si on veut ensuite remettre en place la roue avant, on va procéder de façon inverse comme cela est illustré schématiquement sur la figure 10 :

  • - a) le véhicule repose sur ses trois roues mais aussi sur ses quatre points d'ancrage, la roue avant gauche étant manquante ;
  • - b) on remet en place l'élément de support à géométrie variable 40 en l'accrochant sur la lèvre 15 dans la position longitudinale désirée;
  • - c) on remet en place la roue avant R ;
  • - d) l'opérateur intervient sur les deux bras 43, 44, de préférence en utilisant les allonges 45, 46 associées qu'il aura préalablement tirées, de façon à rapprocher ces deux bras pour les ramener dans une position sensiblement parallèle l'un à l'autre comme cela est illustré par les flèches ;
  • - e) les deux bras 43, 44 ont été ramenés dans la position qui correspond à la configuration active de support, l'effort à vaincre étant un léger effort associé à l'action de la suspension de la roue concernée, et il suffit alors à l'opérateur de verrouiller à nouveau les deux bras en manipulant le levier 47. Ensuite, l'opérateur peut repousser les allonges télescopiques 45, 46 à l'intérieur des bras 43, 44, afin d'éviter la présence d'éléments saillant de façon intempestive ou gênante. On est alors revenu à la position initiale désirée.
    • If we then want to replace the front wheel, we will proceed in reverse as shown schematically in Figure 10:
  • - a) the vehicle rests on its three wheels but also on its four anchor points, the front left wheel being missing;
  • - b) the variable geometry support element 40 is replaced by hooking it onto the lip 15 in the desired longitudinal position;
  • - c) the front wheel R is replaced;
  • - d) the operator intervenes on the two arms 43, 44, preferably using the associated extensions 45, 46 which he has previously pulled, so as to bring these two arms together to bring them back into a substantially parallel position, one to the other as illustrated by the arrows;
  • - e) the two arms 43, 44 have been brought back to the position which corresponds to the active support configuration, the effort to be overcome being a slight effort associated with the action of the suspension of the wheel concerned, and it then suffices the operator to lock the two arms again by manipulating the lever 47. Then, the operator can push the telescopic extensions 45, 46 inside the arms 43, 44, in order to avoid the presence of projecting elements inadvertently or bothersome. We then returned to the desired initial position.

    • Dans certains cas, en particulier pour des véhicules à suspensions très raides et/ou ayant un grand débattement vertical, l'opérateur pourra rencontrer une résistance difficile à vaincre pour rapprocher les deux bras 43,44. On pourra alors utiliser un accessoire (non représenté ici) tel qu'un vérin pneumatique ou mécanique, disposé sous la roue concernée de façon à agir sur celle-ci pour comprimer la suspension associée en relevant légèrement la roue, de sorte que le rapprochement des deux bras 43,44 ne requiert qu'un effort minime. Après utilisation, l'accessoire est enlevé pour ne pas interférer avec les manoeuvres ultérieures.In some cases, especially for vehicles with very stiff suspensions and / or having a large clearance vertical, the operator may encounter resistance difficult to defeat to bring the two arms together 43,44. We can then use an accessory (not shown here) such as a pneumatic or mechanical cylinder, arranged under the wheel concerned so as to act on it to compress the associated suspension by slightly raising the wheel, so that the bringing together of the two arms 43,44 does not require that minimal effort. After use, the accessory is removed so as not to interfere with the maneuvers later.

    Les figures 9 et 10 permettent donc de bien comprendre comment chaque élément de support à géométrie variable 40 évolue entre sa configuration active de support dans laquelle la roue concernée repose sur son élément de support, et sa configuration passive de libération dans laquelle la roue concernée est libérée de son élément de support et peut être démontée ou remontée.Figures 9 and 10 therefore allow a good understanding how each support element with variable geometry 40 evolves between its active support configuration in which the wheel concerned rests on its support, and its passive release configuration in which the wheel concerned is released from its support and can be disassembled or reassembled.

    Avant de redescendre la table, l'opérateur peut desserrer les ancrages au niveau des quatre organes d'ancrage 30, et si nécessaire enlever ces ensembles d'ancrage. En effet, le véhicule V reste porté par ses quatre roues, et peut être redescendu ainsi jusqu'au niveau du sol.Before lowering the table, the operator can loosen the anchors at the level of the four organs anchor 30, and if necessary remove these assemblies anchor. Indeed, vehicle V remains carried by its four wheels, and can be lowered to the level of the ground.

    L'invention n'est pas limitée au mode de réalisation qui vient d'être décrit, mais englobe au contraire toute variante reprenant, avec des moyens équivalents, les caractéristiques essentielles énoncées plus haut.The invention is not limited to the embodiment which has just been described, but on the contrary includes all variant using, with equivalent means, the essential characteristics stated above.
