Abstract

The vehicle lift consists of a support (2) and a lifting system, with the support made from two separate structures (4,5), one of which enables a vehicle to be lifted by its chassis or the underside of its body, while the other enables it to be raised by its wheels. The two structures can be joined together and/or with the lifting system (1) in a detachable arrangement. The support consists of two lengthwise plates or bars (8), attached to the upper end of the lifting system and extending at least partially beneath the lower sides of the vehicle body or chassis between the front and rear wheels, plus two or four panels (9) situated beneath the vehicle's wheels. These are capable of assembly with the lengthwise plates or bars or with the upper ends of the lifting system by means of sliding connectors (10).

Description

La présente invention concerne les dispositifs de manutention, notamment les systèmes élévateurs de charge, et a pour objet un pont élévateur pour véhicules, plus particulièrement pour automobiles, à prise sous roues ou sous caisse.The present invention relates to handling devices, in particular load lifting systems, and relates to a lifting platform for vehicles, more particularly for automobiles, with wheeled or under body socket.

Actuellement, les ponts élévateurs pour véhicules existants font généralement partie de l'un des deux groupes suivants: à prise sous roues ou à prise sous caisse ou châssis.Currently, vehicle lifts for existing vehicles generally belong to one of the following two groups: under-wheel drive or under-body or chassis drive.

Toutefois, de nombreuses opérations de réparations ou de maintenance de véhicules nécessitent successivement l'élévation et le support du véhicule selon les deux modes précités, notamment lorsque le garagiste doit intervenir simultanément ou successivement au niveau de la caisse du véhicule et au niveau des roues ou de leurs accessoires de montage.However, many vehicle repair or maintenance operations successively require the elevation and support of the vehicle according to the two aforementioned modes, in particular when the mechanic must intervene simultaneously or successively at the level of the vehicle body and at the level of the wheels or of their mounting accessories.

Ainsi, le garagiste doit, d'une part, posséder deux ponts élévateurs différents, un de chacun des deux groupes précités, et, d'autre part, déplacer le véhicule d'un pont à l'autre en fonction du type d'opérations de réparations ou de maintenance envisagés.Thus, the garage owner must, on the one hand, have two different lifting lifts, one from each of the two aforementioned groups, and, on the other hand, move the vehicle from one bridge to the other depending on the type of operations. planned repairs or maintenance.

Afin de tenter de remédier à cette situation, il a été proposé des ponts élévateurs intégrant deux dispositifs de soulèvement dont chacun est surmonté d'un support d'appui spécifique réalisant, chacun, l'un des deux modes de soulèvement précités. Il existe notamment de tels ponts élévateurs à prises mixtes constitués par un premier ensemble dispositif de soulèvement/support d'appui sous roues, dans lequel est monté un second ensemble dispositif de soulèvement/support d'appui sous caisse, qui peut en émerger de manière télescopique.In an attempt to remedy this situation, lift lifts have been proposed which integrate two lifting devices, each of which is surmounted by a specific support support, each carrying out one of the two aforementioned lifting modes. There are in particular such lifts with mixed grips constituted by a first lifting device / support support under wheels assembly, in which is mounted a second lifting device / support support under body, which can emerge therefrom telescopic.

Toutefois, la constitution et la structure de tels ponts mixtes existants sont complexes, du fait notamment de la présence de deux dispositifs de soulèvement indépendants et de leurs accessoires de commande, ce qui entraîne en particulier un prix de revient élevé et une maintenance fastidieuse.However, the constitution and structure of such existing composite bridges are complex, due in particular to the presence of two independent lifting devices and their control accessories, which in particular results in a high cost price and tedious maintenance.

La présente invention a notamment pour but de pallier l'ensemble des inconvénients précités, en proposant un pont élévateur ne possédant qu'un seul dispositif de soulèvement mais autorisant les deux modes de soulèvement.The object of the present invention is in particular to overcome all of the aforementioned drawbacks, by proposing a lift having only one lifting device but allowing the two lifting modes.

A cet effet, elle a pour objet un pont élévateur pour véhicules, comprenant essentiellement un dispositif de soulèvement et un support d'appui, monté sur ledit dispositif de soulèvement et destiné à soutenir le véhicule à soulever, caractérisé en ce que le support d'appui est composé de deux ensembles structurels d'appui distincts, dont l'un permet le soulèvement du véhicule avec appui au niveau de la caisse ou du châssis et dont l'autre permet le soulèvement du véhicule avec appui au niveau des roues, les deux ensembles structurels d'appui pouvant être solidarisés entre eux et/ou avec le dispositif de soulèvement de manière amovible.For this purpose, it relates to a vehicle lift, essentially comprising a lifting device and a support support, mounted on said lifting device and intended to support the vehicle to be lifted, characterized in that the support support is composed of two separate structural support sets, one of which allows the vehicle to be raised with support at the body or chassis and the other which allows the vehicle to be raised with support at the wheels, both structural support assemblies which can be secured together and / or with the lifting device in a removable manner.

Comme le montrent les figures 1, 5 et 6 des dessins annexés, le pont élévateur pour véhicules comprend essentiellement un dispositif de soulèvement 1 et un support d'appui 2, monté sur ledit dispositif de soulèvement 1 et destiné à soutenir le véhicule 3.As shown in FIGS. 1, 5 and 6 of the appended drawings, the vehicle lift essentially comprises a lifting device 1 and a support support 2, mounted on said lifting device 1 and intended to support the vehicle 3.

Conformément à l'invention, le support d'appui est composé de deux ensembles structurels d'appui distincts 4 et 5, dont l'un 4 permet le soulèvement du véhicule 3 avec appui au niveau de la caisse 6 ou du châssis et dont l'autre 5 permet le soulèvement du véhicule 3 avec appui au niveau des roues 7, les deux ensembles structurels d'appui 4 et 5 pouvant être solidarisés entre eux et/ou avec le dispositif de soulèvement 1 de manière amovible.According to the invention, the support support is composed of two separate structural support assemblies 4 and 5, one of which 4 allows the lifting of the vehicle 3 with support at the level of the body 6 or the chassis and of which the another 5 allows the lifting of the vehicle 3 with support at the level of the wheels 7, the two structural support assemblies 4 and 5 being able to be joined together and / or with the lifting device 1 in a removable manner.

Selon une première caractéristique de l'invention, représentée notamment aux figures 1, 2 et 3 des dessins annexés, le support d'appui 2 est avantageusement constitué, d'une part, par deux plaques allongées 8 ou deux barres, fixées sur les extrémités supérieures du dispositif de soulèvement 1 et s'étendant au moins partiellement sous les bords latéraux inférieurs de la caisse 6 ou du châssis, situés entre les roues 7 avant et arrière, d'un véhicule 3 disposé sur ledit pont élévateur et, d'autre part, par deux ou quatre portions de plaque 9 situées aux emplacements des roues 7 avant et arrière du véhicule 3 disposé sur ledit pont élévateur et pouvant être assemblées, de manière amovible, avec lesdites plaques allongées 8 ou barres ou avec les extrémités supérieures du dispositif de soulèvement par l'intermédiaire de segments de solidarisation 10 coulissants.According to a first characteristic of the invention, shown in particular in Figures 1, 2 and 3 of the accompanying drawings, the support support 2 is advantageously constituted, on the one hand, by two elongated plates 8 or two bars, fixed on the ends upper parts of the lifting device 1 and extending at least partially under the lower lateral edges of the body 6 or of the chassis, located between the front and rear wheels 7, of a vehicle 3 disposed on said lift and, on the other part, by two or four plate portions 9 located at the locations of the front and rear wheels 7 of the vehicle 3 disposed on said lift and which can be assembled, in a removable manner, with said elongated plates 8 or bars or with the upper ends of the device of lifting by means of sliding securing segments 10.

Par le terme "plaque", on entend dans la présente invention des supports plan et rigide, à savoir, aussi bien des supports ou plateaux pleins, que des supports ajourés ou en forme de caillebotis.By the term "plate" is meant in the present invention flat and rigid supports, namely, both solid supports or trays, as openwork supports or in the form of gratings.

Bien que le premier ensemble structurel d'appui 4 puisse se présenter sous la forme de barres ou rails, pouvant être positionnés par réglage directement sous les longerons du bas de caisse du véhicule 3 à soulever, ou encore sous la forme d'un unique plateau s'étendant sensiblement sur toute la surface du bas de caisse des véhicules 3, il est préféré que ledit premier ensemble structurel 4 consiste en deux plaques allongées 8 présentant une grande surface d'appui (adaptation à des véhicules de largeurs différentes sans réglage), tout en ménageant une ouverture centrale permettant d'accéder au dessous de caisse lorsque le véhicule 3 est soulevé (Figure 7).Although the first structural support assembly 4 may be in the form of bars or rails, which can be positioned by adjustment directly under the side rails of the underbody of the vehicle 3 to be lifted, or even in the form of a single plate extending substantially over the entire surface of the underbody of vehicles 3, it is preferred that said first structural assembly 4 consists of two elongated plates 8 having a large bearing surface (adaptation to vehicles of different widths without adjustment), while providing a central opening allowing access to the underbody when the vehicle 3 is raised (Figure 7).

De même, le second ensemble structurel d'appui 5 peut consister en deux portions de plaques, une pour chaque paire de roues 7 (avant et arrière), ou en quatre portions de plaque 9, une pour chaque roue 7, cette dernière disposition permettant de ménager une ouverture pour accéder aux parties du véhicule 3 situées entre lesdites roues (Figure 7).Similarly, the second structural support assembly 5 can consist of two plate portions, one for each pair of wheels 7 (front and rear), or four plate portions 9, one for each wheel 7, the latter arrangement allowing to provide an opening to access the parts of the vehicle 3 located between said wheels (Figure 7).

Afin d'unifier le second ensemble structurel d'appui 5, les quatre portions de plaque présentes sont avantageusement reliées rigidement entre elles, deux à deux, d'une part, longitudinalement au moyen de longerons 11 s'étendant sous les plaques allongées 8 ou barres formant le premier ensemble structurel 4 du support d'appui 2 et, d'autre part, transversalement, deux à deux, par une ou plusieurs traverses 12, de manière à constituer un second ensemble structurel 5, du support d'appui 2, d'un seul tenant.In order to unify the second structural support assembly 5, the four plate portions present are advantageously rigidly connected together, two by two, on the one hand, longitudinally by means of longitudinal members 11 extending under the elongated plates 8 or bars forming the first structural assembly 4 of the support support 2 and, on the other hand, transversely, two by two, by one or more crosspieces 12, so as to constitute a second structural assembly 5, of the support support 2, in one piece.

Comme le montrent plus particulièrement les figures 2 et 3 des dessins annexés, les segments de solidarisation 10 coulissants, préférentiellement au moins un pour chaque portion de plaque 9, sont guidés dans des glissières 13 fixées sous les portions de plaques 9 destinées à l'appui des roues 7 ou sur les longerons 11 reliant lesdites portions de plaque 9 entre elles, deux à deux, et peuvent être déplacées, de manière alternative, d'une position escamotée, correspondant à une non utilisation du second ensemble structurel d'appui 5, vers une position déployée dans laquelle ils s'engagent partiellement dans des glissières ou par dessus des appuis 14 monté(e)s sous les plaques allongées 8 ou sur les barres du premier ensemble structurel d'appui 4.As shown more particularly in FIGS. 2 and 3 of the appended drawings, the sliding securing segments 10, preferably at least one for each plate portion 9, are guided in slides 13 fixed under the plate portions 9 intended to support the wheels 7 or on the side members 11 connecting said plate portions 9 together, in pairs, and can be moved, alternatively, from a retracted position, corresponding to a non-use of the second structural support assembly 5, towards a deployed position in which they partially engage in slides or over supports 14 mounted under the elongated plates 8 or on the bars of the first structural support assembly 4.

En vue d'éviter en particulier toute désolidarisation intempestive ou involontaire du second ensemble structurel d'appui 5 d'avec le premier ensemble structurel d'appui 4, en position déployée ou au cours d'un déplacement du pont élévateur, il est avantageusement prévu que le déplacement des segments de solidarisation 10 coulissants ne peut être effectué qu'en position basse ou totalement repliée dudit pont élévateur, le ou les moyens d'actionnement 15 prévus à cet effet étant mécaniquement désolidarisés et séparés des organes d'entraînement 16 desdits segments de solidarisation 10 lors du déploiement du dispositif de soulèvement 1 et du soulèvement du support d'appui 2, c'est-à-dire du premier ensemble structurel d'appui 4 seul ou des premier et second ensembles structurels d'appui 4 et 5 simultanément (Figures 1 et 5 des dessins annexés).In order to avoid in particular any untimely or involuntary separation of the second structural support assembly 5 from the first structural support assembly 4, in the deployed position or during a movement of the lift, it is advantageously provided that the displacement of the sliding fastening segments 10 can only be carried out in the low or fully folded position of said lift, the actuating means or means 15 provided for this purpose being mechanically separated and separated from the drive members 16 of said segments joining 10 during deployment of the lifting device 1 and the lifting of the support support 2, that is to say of the first structural support assembly 4 alone or of the first and second structural support assemblies 4 and 5 simultaneously (Figures 1 and 5 of the accompanying drawings).

Ainsi, le choix du mode de soulèvement s'effectue lorsque le pont élévateur est en position basse, l'assemblage entre premier et second ensembles structurels d'appui 4 et 5 étant verrouillé et bloqué, lorsqu'il est effectif, du fait de l'action du poids dudit second ensemble structurel 5 et, le cas échéant, du véhicule 3 soulevé sur les liaisons glissières 13/segments de solidarisation 10/appuis 14.Thus, the choice of lifting mode is made when the lift is in the low position, the assembly between first and second structural support assemblies 4 and 5 being locked and blocked, when it is effective, due to the action of the weight of said second structural assembly 5 and, if necessary, of the vehicle 3 raised on the slide links 13 / securing segments 10 / supports 14.

Selon une caractéristique de l'invention, les moyens d'actionnement consistent en au moins un vérin 15 monté sur la partie basse ou sur l'embase du dispositif de soulèvement 1 et dont la tige 15' porte un embout connecteur 17 et, comme le montrent les figures 1 et 5 des dessins annexés, les organes d'entraînement 16 comportent au moins un organe d'accrochage 18 pouvant venir en prise, chacun, avec au moins un embout connecteur 17 pour la transmission du mouvement de translation de la tige 15' du vérin 15 correspondant, au(x) segment(s) de solidarisation 10 relié(s) auxdits organes d'entraînement 16, l'engagement et le désengagement de chaque organe d'accrochage 18 avec l'embout connecteur 17 correspondant s'effectuant par simple déplacement vertical, généré lors du soulèvement ou de l'abaissement du pont élévateur.According to a characteristic of the invention, the actuation means consist of at least one jack 15 mounted on the lower part or on the base of the lifting device 1 and of which the rod 15 ′ carries a connector end piece 17 and, as shown in FIGS. 1 and 5 of the appended drawings, the drive members 16 comprise at least one attachment member 18 which can come into engagement, each with at least one end piece connector 17 for the transmission of the translational movement of the rod 15 ′ of the jack 15 corresponding to the securing segment (s) 10 connected to said drive members 16, the engagement and disengagement of each member hooking 18 with the corresponding connector end piece 17 being effected by simple vertical displacement, generated during raising or lowering of the lift.

Les segments de solidarisation 10, préférentiellement sous la forme de portions de barres à section rectangulaire pourvues d'un rebord frontal inférieur en biseau, peuvent être actionnés chacun par des moyens d'actionnement propres par l'intermédiaire d'autant d'organes d'entraînement adaptés ou éventuellement par paire, notamment par paires opposées dont chacune peut être reliée à un vérin en vue d'un déplacement desdits segments de solidarisation, des portions de plaque considérées vers les plaques allongées ou réciproquement.The securing segments 10, preferably in the form of portions of bars of rectangular section provided with a lower beveled front edge, can each be actuated by own actuation means by means of as many organs suitable drive or optionally in pairs, in particular in opposite pairs, each of which can be connected to a jack for the purpose of moving said fastening segments, from the plate portions considered towards the elongated plates or vice versa.

Conformément à un mode de réalisation préféré de l'invention, représenté aux figures 1, 2, 3 et notamment 4 des dessins annexés, les segments de solidarisation 10 sont logés dans des glissières 13 fixés sur les longerons 11 reliant les portions de plaque 9 entre elles, deux à deux, et peuvent s'étendre, en position d'assemblage des deux ensembles structurels 4 et 5 du support d'appui 3, par dessus des appuis 14 prévus sur la face inférieure des plaques allongées 8 du premier ensemble structurel d'appui 4, lesdits segments de solidarisation 10 étant reliés entre eux longitudinalement, deux à deux, par des tringles 19. En outre, il peut être prévu, d'une part, un unique organe d'entraînement 16, reliant transversalement deux des segments de solidarisation 10 et pourvu d'un organe d'accrochage 18 consistant en une plaquette verticale munie d'une découpe en forme d'encoche 18' et, d'autre part, un unique moyen d'actionnement, pour le déplacement desdits segments de solidarisation 10, sous la forme d'un vérin 15 monté sur la partie basse ou sur l'embase du dispositif de soulèvement 1, ne pouvant être actionné qu'en position basse du pont élévateur et comportant un embout connecteur 17 à deux butées 17' sur sa tige 15' de telle manière que la plaquette verticale 18 formant organe d'accrochage peut s'engager entre les deux butées 17' et la partie médiane 17'' de l'embout 17 s'insérer dans l'encoche 18' de ladite plaquette verticale 18 lorsque ledit pont élévateur arrive en position basse.In accordance with a preferred embodiment of the invention, shown in Figures 1, 2, 3 and in particular 4 of the accompanying drawings, the securing segments 10 are housed in slides 13 fixed on the side members 11 connecting the plate portions 9 between they, two by two, and can extend, in the assembly position of the two structural assemblies 4 and 5 of the support support 3, over the supports 14 provided on the underside of the elongated plates 8 of the first structural assembly d 'support 4, said securing segments 10 being interconnected longitudinally, two by two, by rods 19. In addition, there may be provided, on the one hand, a single drive member 16, transversely connecting two of the segments of attachment 10 and provided with a fastening member 18 consisting of a vertical plate provided with a notch-shaped cutout 18 'and, on the other part, a single actuating means, for the displacement of said securing segments 10, in the form of a jack 15 mounted on the lower part or on the base of the lifting device 1, can only be actuated in position bottom of the lift and comprising a connector end piece 17 with two stops 17 'on its rod 15' so that the vertical plate 18 forming a hooking member can engage between the two stops 17 'and the middle part 17'' of the nozzle 17 insert into the notch 18 'of said vertical plate 18 when said lift reaches the low position.

Selon une première variante de réalisation de l'invention représentée aux figures 6A et 6B des dessins annexés, le dispositif de soulèvement 1 peut consister en un ensemble de deux colonnes latérales 20 dont les paliers supports coulissants 20' sont solidaires des plaques allongées 8 ou barres du premier ensemble structurel d'appui 4.According to a first embodiment of the invention shown in Figures 6A and 6B of the accompanying drawings, the lifting device 1 may consist of a set of two lateral columns 20 whose sliding support bearings 20 'are integral with the elongated plates 8 or bars of the first structural support unit 4.

Selon une seconde variante de réalisation préférentielle de l'invention, et comme le montrent les figures 1 et 5 des dessins annexés, le dispositif de soulèvement 1 est constitué par une structure articulée déformable en double ciseaux ou en double pantographes, pouvant être déployé chacun sous l'action d'un vérin de puissance 21 correspondant, actionnés ensemble de manière complémentaire, de manière à obtenir un déploiement symétrique et équilibré des deux ciseaux ou pantographes.According to a second preferred embodiment of the invention, and as shown in Figures 1 and 5 of the accompanying drawings, the lifting device 1 is constituted by an articulated structure deformable in double scissors or in double pantographs, which can each be deployed under the action of a corresponding power jack 21, actuated together in a complementary manner, so as to obtain a symmetrical and balanced deployment of the two scissors or pantographs.

La structure et le fonctionnement de ces derniers sont connus en tant que tels de l'homme du métier et ressortent de manière évidente des figures 1 et 5 des dessins annexés, aucune explication supplémentaire n'étant de ce fait nécessaire pour leur compréhension.The structure and operation of these are known as such to those skilled in the art and are evident from Figures 1 and 5 of the accompanying drawings, no further explanation is therefore necessary for their understanding.

On peut toutefois noter que dans le cas du pont à ciseaux représenté sur lesdites figures 1 et 5, les liaisons entre le dispositif de soulèvement et le sol, d'une part, ou le support d'appui, d'autre part, se fait par l'intermédiaire d'une liaison pivot et d'une liaison chemin de roulement/galet, coopérant entre elles.It may however be noted that in the case of the scissor bridge shown in said Figures 1 and 5, the connections between the lifting device and the ground, on the one hand, or the support support, on the other part, is done via a pivot link and a raceway / roller link, cooperating with each other.

Conformément à une autre caractéristique de l'invention, représentée notamment aux figures 1 et 5 des dessins annexés, le second ensemble structurel d'appui 5 est, en cas de non solidarisation avec le premier ensemble structurel d'appui 4, et lors du déploiement dudit pont élévateur, soulevé jusqu'à et maintenu dans une position intermédiaire au moyen de points supports 22, 23 montés sur les parties inférieures des bras 1' des ciseaux ou des pantographes formant le dispositif de soulèvement 1.In accordance with another characteristic of the invention, shown in particular in FIGS. 1 and 5 of the accompanying drawings, the second structural support assembly 5 is, in the event of non-attachment to the first structural support assembly 4, and during deployment of said lift, raised up to and maintained in an intermediate position by means of support points 22, 23 mounted on the lower parts of the arms 1 'of the scissors or pantographs forming the lifting device 1.

Cette disposition permet de procéder, dans le cas d'une configuration du support d'appui 2 pour un soulèvement avec prise ou appui sous la caisse ou coque du véhicule 3, d'entamer le soulèvement avec appui des roues 7 sur les portions de plaque 9 (figure 5A), puis, lorsque les plaques allongées 8 ou les cales en caoutchouc posées sur ces dernières entrent en contact avec le bas de la caisse du véhicule 3, de décoller progressivement ledit véhicule de son appui sur les portions de plaque 9 et de l'amener en position de soulèvement maximal, en reposant entièrement sur le premier ensemble structurel d'appui 4.This arrangement makes it possible to proceed, in the case of a configuration of the support support 2 for a lifting with grip or support under the body or shell of the vehicle 3, to initiate the lifting with support of the wheels 7 on the plate portions 9 (FIG. 5A), then, when the elongated plates 8 or the rubber wedges placed on the latter come into contact with the bottom of the body of the vehicle 3, gradually take off said vehicle from its support on the plate portions 9 and bring it to the maximum lifting position, resting entirely on the first structural support assembly 4.

Ainsi, le soulèvement du véhicule 3 avec prise ou appui sous la caisse ou le châssis de ce dernier, se fait de manière progressive au cours du mouvement de soulèvement, du fait du différentiel de vitesse de montée entre le premier 4 et le second 5 ensemble structurel d'appui et non pas en début de soulèvement et par à-coup ou de manière brutale.Thus, the lifting of the vehicle 3 with grip or support under the body or the chassis of the latter, is done gradually during the lifting movement, due to the differential speed of climb between the first 4 and the second 5 together structural support and not at the start of lifting and suddenly or suddenly.

En outre, les portions de plaque 9 constituent, dans leur position de soulèvement intermédiaire, des tables ou des plans de travail à mi-hauteur permettant le dépôt d'outils, d'appareils, de parties démontées du véhicule, de pièces de rechange ou analogues (Fig. 1 et 5C).In addition, the plate portions 9 constitute, in their intermediate lifting position, tables or worktops at mid-height allowing the deposition of tools, devices, dismantled parts of the vehicle, spare parts or analogues (Fig. 1 and 5C).

Comme le montrent les figures 1 et 3B des dessins annexés, les points supports 22, 23 peuvent avantageusement consister, d'une part, en deux paliers ouverts concaves 22 recevant un axe transversal ou deux ergots 24, solidaires des longerons 11 ou des portions de plaque 9 pour une liaison pivot amovible par soulèvement, et, d'autre part, en deux galets 23 sur lesquels prennent appui des chemins de roulement correspondants 25 solidaires des longerons 11 reliant les portions de plaque 9 entre elles, lesdits paliers 22 et galets 23 étant installés à des emplacements similaires sur des bras opposés 1' d'un même ciseau 1 ou pantographe.As shown in Figures 1 and 3B of the accompanying drawings, the support points 22, 23 may advantageously consist of a on the one hand, in two concave open bearings 22 receiving a transverse axis or two lugs 24, integral with the side members 11 or plate portions 9 for a removable pivot connection by lifting, and, on the other hand, in two rollers 23 on which are supported corresponding raceways 25 integral with the side members 11 connecting the plate portions 9 to each other, said bearings 22 and rollers 23 being installed at similar locations on opposite arms 1 ′ of the same chisel 1 or pantograph.

Cette liaison, amovible par soulèvement, entre le second ensemble structurel d'appui 5 et le dispositif de soulèvement 1 permet audit ensemble structurel 5 d'être soulevé et soutenu par ce dernier, sans que toutefois cet accrochage articulé n'interfère avec le repliement ou l'écartement des bras 1' des ciseaux ou des pantographes.This link, removable by lifting, between the second structural support assembly 5 and the lifting device 1 allows said structural assembly 5 to be lifted and supported by the latter, without however this articulated attachment interfering with the folding or the spacing of the arms 1 'of scissors or pantographs.

En outre et de manière avantageuse, il peut être prévu que, en position basse dudit pont élévateur, le premier et le second ensembles structurels d'appui 4 et 5 reposent sur des appuis au sol 26 ou sur l'embase du dispositif de soulèvement 1 et les glissières 13 guidant les segments de solidarisation 10 sont alignées avec les glissières ou les appuis 14 correspondant du premier ensemble structurel 4 de telle manière que lesdits segments de solidarisation 10 puissent être engagés ou désengagés par rapport auxdites glissières ou auxdits appuis 14 par l'intermédiaire des organes d'entraînement 16 commandés par les moyens d'actionnement 15, ce même en cas de présence d'un véhicule 3 sur ledit pont élévateur, lesdits moyens d'actionnement 15 étant bloqués lorsque ce dernier quitte ladite position basse (Fig. 1 et 5A).In addition and advantageously, it can be provided that, in the lower position of said lift, the first and second structural support assemblies 4 and 5 rest on ground supports 26 or on the base of the lifting device 1 and the slides 13 guiding the securing segments 10 are aligned with the corresponding slides or supports 14 of the first structural assembly 4 so that said securing segments 10 can be engaged or disengaged relative to said slides or said supports 14 by the intermediate the drive members 16 controlled by the actuating means 15, even in the presence of a vehicle 3 on said lift, said actuating means 15 being blocked when the latter leaves said low position (FIG. 1 and 5A).

Conformément à une caractéristique supplémentaire de l'invention, non représentée aux dessins annexés, le pont élévateur peut également comporter, d'une part, un ou plusieurs détecteurs de position ou fins de course 11 n'autorisant la manoeuvre des moyens d'actionnement 15 en vue du déplacement des segments de solidarisation 10 qu'en position basse ou repliée du pont élévateur, et, d'autre part, un ou plusieurs détecteurs de position ou fins de course empêchant tout mouvement du dispositif de soulèvement 1 lorsque les segments de solidarisation 10 ne sont pas disposés dans une position d'engagement ou de dégagement total par rapport aux glissières ou aux appuis 14 correspondant faisant partie du premier ensemble structurel d'appui 4.In accordance with an additional characteristic of the invention, not shown in the accompanying drawings, the lift can also comprise, on the one hand, one or more position detectors or limit switches 11 not authorizing the operation of the actuating means 15 with a view to moving the securing segments 10 only in the low or folded position of the lift, and, on the other hand, one or more position detectors or limit switches preventing any movement of the lifting device 1 when the securing segments 10 are not disposed in a position of engagement or total clearance relative to the slides or to the corresponding supports 14 forming part of the first structural support assembly 4.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments, ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiments described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements, or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
