Description

CHARIOT MOBILE PORTE-CHARGE COMPORTANT UN DISPOSITIF DE VERROUILLAGE A L’INTERIEUR D’UN VEHICULE DE TRANSPORT MOBILE LOAD-CARRYING TROLLEY COMPRISING A LOCKING DEVICE INSIDE A TRANSPORT VEHICLE
[0001] La présente invention se rapporte aux chariots porte-charge qui sont mobiles à l’intérieur d’un véhicule de transport de manière à pouvoir embarquer une charge externe à l’intérieur du véhicule. L’invention concerne plus particulièrement un dispositif de sécurité apte à bloquer le chariot à l’intérieur du véhicule en position de transport tout en étant apte à informer l’utilisateur. The present invention relates to load carriers which are mobile inside a transport vehicle so as to be able to carry an external load inside the vehicle. The invention relates more particularly to a safety device capable of blocking the trolley inside the vehicle in the transport position while being capable of informing the user.
[0002] Dans le cadre des véhicules de transport, par exemple utilitaires, il est nécessaire de pouvoir passer d’un usage à un autre rapidement ou de rendre le véhicule polyvalent afin d’optimiser le taux d’utilisation d’un véhicule de transport. Ceci est d’autant plus utile dans le cadre d’une flotte de véhicules électriques, quand on souhaite utiliser un même véhicule dans différentes activités pour amortir son coût initial. Pour cela, l’utilisation d’un chariot mobile et extractible du véhicule dans le but d’embarquer une charge externe du type atelier, ou module de camping ou module de stockage de marchandises ou de type module frigorifique, etc. permet de dissocier le véhicule de son usage et d’aménager rapidement son équipement intérieur. Pour cela, il est nécessaire de pouvoir de retirer l’ensemble formé par le chariot mobile et la charge externe de la zone de chargement du véhicule, en un seul bloc, pour pouvoir ainsi vider le véhicule rapidement et ensuite pouvoir le recharger avec une charge différente tout aussi rapidement. Ainsi, en adaptant facilement le véhicule à son usage, un même véhicule peut servir différents métiers, ou avoir plusieurs utilisations. [0002] In the context of transport vehicles, for example utility vehicles, it is necessary to be able to switch from one use to another quickly or to make the vehicle versatile in order to optimize the rate of use of a transport vehicle. . This is all the more useful in the context of a fleet of electric vehicles, when you want to use the same vehicle in different activities to amortize its initial cost. For this, the use of a mobile and extractable trolley from the vehicle in order to embark an external load of the workshop type, or camping module or goods storage module or refrigeration module type, etc. makes it possible to dissociate the vehicle from its use and to quickly adapt its interior equipment. For this, it is necessary to be able to remove the assembly formed by the mobile carriage and the external load from the loading area of the vehicle, in a single block, in order thus to be able to empty the vehicle quickly and then to be able to recharge it with a load. different just as quickly. Thus, by easily adapting the vehicle to its use, the same vehicle can serve different trades, or have several uses.
[0003] On connaît différentes solutions permettant d’équiper un véhicule utilitaire d’un chariot mobile apte à porter une charge et à la déplacer à l’extérieur du véhicule. Une telle solution est décrite dans le document EPI 026063. Ce document décrit un chariot mobile pour un véhicule utilitaire comportant un plateau porte-charge équipé de quatre pieds munis chacun d’une roue à son extrémité libre, les deux pieds avant, respectivement arrière, étant rabattables et réglables en hauteur simultanément. Le chariot mobile selon ce document est muni de plusieurs butées avant et arrière qui viennent chacune au contact d’une butée en vis- à-vis prévue, elle, sur une surface de réception du véhicule afin d’assurer le blocage en position du chariot par rapport au véhicule. Pour ce faire, la venue en prise et le dégagement des butées du chariot mobile et du véhicule est possible uniquement en effectuant un ajustement en hauteur des pieds avant et arrière. Une telle opération nécessite de multiples manœuvres de réglage et de vérification successives des différentes positions des composants du chariot par rapport au véhicule de la part de l’opérateur, ce qui implique beaucoup de temps pour rentrer et sortir le chariot du véhicule. De surcroît, en cas de montage défectueux ou de disfonctionnement desdites butées, le chariot risque de ne plus être bien arrimé, sans pour autant que l’opérateur en ait connaissance. [0003] Various solutions are known which make it possible to equip a commercial vehicle with a mobile carriage able to carry a load and to move it outside the vehicle. Such a solution is described in the document EPI 026063. This document describes a mobile carriage for a utility vehicle comprising a load-carrying platform equipped with four feet each provided with a wheel at its free end, the two front feet, respectively rear, being foldable and height adjustable simultaneously. The mobile carriage according to this document is provided with several front and rear stops which each come into contact with a stop opposite provided, it, on a receiving surface of the vehicle in order to ensure the blocking in position of the carriage relative to the vehicle. To do this, the engagement and disengagement of the stops of the mobile carriage and of the vehicle is possible only by carrying out a height adjustment of the front and rear feet. Such an operation requires multiple successive maneuvers of adjustment and verification of the different positions of the components of the carriage relative to the vehicle on the part of the operator, which involves a lot of time to enter and exit the carriage from the vehicle. In addition, in the event of defective assembly or malfunction of said stops, the carriage risks no longer being well secured, without the operator being aware of this.
[0004] Un objectif de l’invention est de remédier aux inconvénients précités et d’apporter une solution originale pour un dispositif de sécurité pour un chariot mobile porte- charge permettant de bloquer rapidement le chariot à l’intérieur du véhicule en position de transport, tout en étant apte à en informer l’utilisateur. [0004] An object of the invention is to remedy the aforementioned drawbacks and to provide an original solution for a safety device for a mobile load-carrying trolley making it possible to quickly block the trolley inside the vehicle in the transport position. , while being able to inform the user thereof.
[0005] Cet objectif est atteint par l’invention qui propose un chariot mobile porte-charge comportant un plateau porte-charge et des moyens de déplacement aptes à assurer le déplacement du plateau à l’intérieur d’un véhicule de transport entre une position complètement rentrée dans un espace de réception à l’arrière du véhicule et une position sortie de celui-ci, ledit chariot comportant des moyens de blocage en position rentrée dans le véhicule dudit plateau porte-charge, caractérisé en ce que lesdits moyens de blocage comportent un levier d’actionnement de moyens de verrouillage du plateau entre une première position dans laquelle les moyens de verrouillage sont déverrouillés de façon à permettre un mouvement du plateau par rapport au véhicule et une deuxième position de blocage du plateau dans laquelle les moyens de verrouillage sont verrouillés de façon à empêcher un mouvement du plateau par rapport au véhicule et en ce que le levier est réalisé de manière à être protubérant par rapport à l’extrémité arrière du plateau en position de déverrouillage et à s’effacer par rapport à l’extrémité arrière du plateau lorsque ledit levier est en position de verrouillage du plateau. [0005] This objective is achieved by the invention which proposes a mobile load-carrying carriage comprising a load-carrying plate and displacement means capable of ensuring the displacement of the plate inside a transport vehicle between a position completely retracted into a reception space at the rear of the vehicle and an extended position therefrom, said carriage comprising means for locking said load-carrying platform in the retracted position in the vehicle, characterized in that said locking means comprise a lever for actuating means for locking the platform between a first position in which the locking means are unlocked so as to allow movement of the platform relative to the vehicle and a second position for locking the platform in which the locking means are locked so as to prevent movement of the tray relative to the vehicle and in that the lever is made so as to protrude relative to the rear end of the tray in the unlocked position and to disappear relative to the end rear of the tray when said lever is in the tray locking position.
[0006] Autrement dit, l’invention propose un dispositif de blocage en position de transport du chariot porte-charge, à l’intérieur d’un véhicule de transport, ledit dispositif comportant un levier protubérant par rapport à l’extrémité arrière du chariot en position de déblocage du chariot. Par extrémité arrière du chariot on comprend l’extrémité situé à l’arrière du véhicule de transport, par opposition à son extrémité avant, située plus proche de l’avant du véhicule. [0007] Plus particulièrement selon l’invention, le levier d’actionnement du dispositif de blocage passe d’une première position dans laquelle il est protubérant par rapport à l’extrémité arrière du chariot, lorsque ce dernier est débloqué ou déverrouillé et peut être déplacé, à une deuxième position dans laquelle il s’efface par rapport à l’extrémité arrière du chariot lorsque celui-ci est en position verrouillée, donc sans possibilité aucune de déplacement à l’intérieur du véhicule de transport. Ainsi, lorsque le levier s’efface, le chariot étant complètement rentré dans l’espace de réception à l’intérieur du véhicule de transport, l’opérateur peut fermer les portes du véhicule, ce qui n’est pas possible avec un levier protubérant, qui témoigne de la position débloquée du chariot. Le levier est bien entendu dimensionné de manière à ce que, en position déverrouillée du plateau, il soit protubérant par rapport à l’espace de réception du véhicule de manière à empêcher la fermeture des portes du véhicule. In other words, the invention provides a device for locking the load-carrying trolley in the transport position, inside a transport vehicle, said device comprising a lever projecting with respect to the rear end of the trolley in the carriage release position. The rear end of the carriage is understood to mean the end located at the rear of the transport vehicle, as opposed to its front end, located closer to the front of the vehicle. [0007] More particularly according to the invention, the actuating lever of the locking device passes from a first position in which it protrudes with respect to the rear end of the carriage, when the latter is unlocked or unlocked and can be moved, to a second position in which it disappears relative to the rear end of the carriage when the latter is in the locked position, therefore without any possibility of movement inside the transport vehicle. Thus, when the lever disappears, the truck being completely retracted in the reception space inside the transport vehicle, the operator can close the doors of the vehicle, which is not possible with a protruding lever , which testifies to the unlocked position of the carriage. The lever is of course dimensioned so that, in the unlocked position of the plate, it protrudes with respect to the reception space of the vehicle so as to prevent the doors of the vehicle from closing.
[0008] Ceci permet de s’assurer que le chariot porte-charge (qui est amené à porter des charges assez lourdes de l’ordre de quelques centaines de kg) est bien ancré dans le véhicule, en étant verrouillé ou bloqué en position de transport, sans aucune possibilité de déplacement. Ceci assure une sécurité accrue lors du déplacement du véhicule, tout en permettant d’en informer l’opérateur. [0008] This makes it possible to ensure that the load carrier (which is required to carry fairly heavy loads of the order of a few hundred kg) is well anchored in the vehicle, being locked or blocked in the position of transport, without any possibility of movement. This ensures increased safety when moving the vehicle, while allowing the operator to be informed.
[0009] Dans un mode préféré de réalisation de l’invention, les moyens de verrouillage peuvent comprendre une butée prévue pour coopérer avec une encoche fixée à l’intérieur dudit espace de réception du véhicule qui est mobile entre une première position de déverrouillage du plateau dans laquelle la butée ne coopère pas avec l’encoche et une deuxième position de verrouillage du plateau dans laquelle la butée est insérée à l’intérieur de l’encoche. Dans d’autres mode de réalisation de l’invention, les moyens de verrouillage peuvent comprendre un dispositif à loquet, du type comprenant un pêne et une gâche ou crochet rotatif ou encore un système magnétique du type à électroaimant, etc. In a preferred embodiment of the invention, the locking means may comprise a stop provided to cooperate with a notch fixed inside said reception space of the vehicle which is movable between a first unlocking position of the plate in which the stopper does not cooperate with the notch and a second locking position of the plate in which the stopper is inserted inside the notch. In other embodiments of the invention, the locking means may comprise a latch device, of the type comprising a bolt and a keeper or rotary hook or even a magnetic system of the electromagnet type, etc.
[0010] Ledit levier peut être relié à une bielle munie d’un pivot central et de deux articulations rotatives d’extrémité reliant la bielle à des bras d’actionnement de ladite butée mobile. [0011] L’axe longitudinal dudit levier peut passer par le centre de rotation dudit pivot et il est incliné par rapport à la direction longitudinale de ladite bielle. Ainsi, grâce à l’inclinaison du levier, celui-ci peut se loger dans un logement du cadre du plateau, en retrait par rapport à l’extrémité arrière du plateau du chariot. [0010] Said lever can be connected to a connecting rod provided with a central pivot and two rotary end joints connecting the connecting rod to actuating arms of said mobile stop. The longitudinal axis of said lever can pass through the center of rotation of said pivot and it is inclined with respect to the longitudinal direction of said connecting rod. Thus, thanks to the inclination of the lever, the latter can be housed in a recess in the frame of the tray, set back with respect to the rear end of the tray of the carriage.
[0012] Le plateau porte-charge peut être supporté par quatre pieds munis chacun d’une roue à son extrémité libre lui permettant de se déplacer et de prendre appui au sol lorsqu’il est en position sortie, lesdits pieds étant escamotables entre une position dépliée quand ils prennent appui au sol et une position repliée quand ils se trouvent au niveau du plateau ou au-dessus de celui-ci. [0012] The load-carrying platform can be supported by four feet each provided with a wheel at its free end allowing it to move and bear on the ground when it is in the extended position, said feet being retractable between a position unfolded when they rest on the ground and a folded position when they are at the level of the platform or above it.
[0013] Ledit levier peut être réalisé de manière à empêcher le passage en position dépliée des pieds du plateau porte-charge en position de verrouillage du plateau.

[0022] La figure 1 illustre de manière schématique la partie arrière d’un véhicule de transport 100 de type van et d’un chariot 1 porte-charge de l’invention apte à être introduit dans un espace de réception 110 du véhicule. Le chariot 1 comprend un plateau 2 porte- charge réalisé sous forme d’un cadre 3 métallique, plus particulièrement métallo-soudé à base de longerons et traverses métalliques lui conférant la rigidité nécessaire pour supporter une charge de quelques centaines de kg. Le plateau 2 présente une surface plane sur laquelle est fixé un plancher 4 supporté par le cadre 3. Le chariot 1 comporte une extrémité avant 5 a et une extrémité arrière 5b, tel que défini par rapport aux parties avant et arrière du véhicule 100, et il est supporté à chacune de ses extrémités par une paire de pieds avant 6a et une paire de pieds arrière 6b, comme visible sur la figure 2. [0022] Figure 1 schematically illustrates the rear part of a transport vehicle 100 of the van type and of a load-carrying trolley 1 of the invention capable of being introduced into a reception space 110 of the vehicle. The trolley 1 comprises a load-carrying plate 2 made in the form of a metal frame 3, more particularly metal-welded based on metal longitudinal members and crosspieces giving it the rigidity necessary to support a load of a few hundred kg. The plate 2 has a flat surface on which is fixed a floor 4 supported by the frame 3. The carriage 1 has a front end 5a and a rear end 5b, as defined with respect to the front and rear parts of the vehicle 100, and it is supported at each of its ends by a pair of front legs 6a and a pair of rear legs 6b, as shown in Figure 2.
[0023] Les pieds avant 6a et arrière 6b sont munis de roues 7a, respectivement 7b à leur extrémités libres destinées à prendre appui sur le sol. Les pieds avant 6a et arrière 6b son escamotables entre une première position de pliée dans laquelle ils sont rangés au sein du plateau et une deuxième position dépliée dans laquelle leurs roues respectives prennent appui au sol. Les deux pieds avant 6a sont télescopiques et reliés cinématiquement ensemble de manière à pouvoir être réglés en hauteur simultanément, notamment en actionnant une manivelle qui entraîne un mécanisme de type écrou/vis sans fin, ou à l’aide d’un vérin électrique. Il en est de même pour les pieds arrière 6b qui sont également reliés cinématiquement et réglables en hauteur simultanément. Les roues arrière 7b sont orientables et les roues avant 7a sont non orientables afin de rendre le chariot plus maniable. The front 6a and rear 6b legs are provided with wheels 7a, 7b respectively at their free ends intended to rest on the ground. The front 6a and rear 6b legs are retractable between a first folded position in which they are stored within the tray and a second unfolded position in which their respective wheels bear on the ground. The two front legs 6a are telescopic and kinematically connected together so that they can be adjusted in height simultaneously, in particular by actuating a crank which drives a mechanism of the nut/worm type, or using an electric jack. It is the same for the rear feet 6b which are also connected kinematically and adjustable in height simultaneously. The rear wheels 7b are steerable and the front wheels 7a are non-steerable in order to make the carriage more manageable.
[0024] Le chariot 1 comprend plusieurs supports 8 verticaux s’étendant vers le haut en étant perpendiculaires à la surface du plancher 4. Les supports 8 ont pour rôle de maintenir et/ou guider les aménagements nécessaires correspondant à la charge à transporter. Dans l’exemple illustré aux figures 2 à 4, le chariot 1 est prévu pour l’installation d’un atelier à plusieurs étagères (non illustrées sur les dessins) destinées à supporter les caisses à outils. Dans ce cas, les supports 8 ont une forme en T, dont la partie supérieure horizontale forme une traverse 8a qui sert de moyen de guidage en translation horizontale, dans une direction transverse au plateau, de différentes étagères. En effet, les étagères se faisant face selon la direction longitudinale du chariot 1 sont rapprochées transversalement lors de l’introduction du chariot 1 dans l’espace de réception 110 du véhicule et elles sont amenées à s’écarter transversalement l’une par rapport à l’autre afin d’occuper tout le volume de l’espace de réception 110, plus particulièrement l’espace au-dessus des roues. The carriage 1 comprises several vertical supports 8 extending upwards being perpendicular to the surface of the floor 4. The supports 8 have the role of maintaining and/or guiding the necessary arrangements corresponding to the load to be transported. In the example shown in Figures 2 to 4, the trolley 1 is provided for the installation of a workshop with several shelves (not shown in the drawings) intended to support the tool boxes. In this case, the supports 8 have a T-shape, the upper horizontal part of which forms a crosspiece 8a which serves as a means of guiding in horizontal translation, in a direction transverse to the plate, of the various shelves. Indeed, the shelves facing each other in the longitudinal direction of the carriage 1 are brought together transversely when the carriage 1 is introduced into the reception space 110 of the vehicle and they are caused to move apart transversely from one another. the other in order to occupy the entire volume of the reception space 110, more particularly the space above the wheels.
[0025] La partie gauche de la figure 2 illustre un équipement d’ancrage 50 qui est pourvu de moyens de fixation au plancher du véhicule, à l’intérieur de l’espace de réception 110, et forme ainsi une interface de guidage du chariot 1, illustré dans la partie droite de la figure 2, en position complètement sortie du véhicule. Plus particulièrement, l’équipement d’ancrage 50 comporte plusieurs éléments de guidage latéraux 51, 52, 53, 54 répartis sur la longueur de l’espace de réception 110 et une traverse 55 formant une butée avant pour le chariot 1. Les éléments de guidage latéraux 51, 53 font face aux éléments de guidage en vis- à-vis 52, 54 en étant espacés d’une distance sensiblement égale à la largeur du chariot 1. Ils sont munis chacun d’une ou plusieurs roulettes 57 libres en rotation autour d’un axe vertical (ou perpendiculaire au plancher du véhicule) qui viennent au contact des côtés longitudinaux 9 du cadre 3 du chariot 1 et assurent son guidage en coulissement lors de son déplacement dans l’espace de réception 110 du véhicule. Afin de permettre le déplacement du chariot 1, la surface inférieure (faisant face au plancher du véhicule) est munie de roulettes 10 (fïg. 3) à l’aide desquelles il se déplace sur le plancher de l’espace de réception 110. Les roulettes 10 forment les moyens de déplacement du chariot 1 à l’intérieur du véhicule. Le déplacement peut être effectué manuellement par l’opérateur ou à l’aide d’un vérin électrique qui est actionné pour pousser ou tirer le chariot. La traverse 55 comprend par ailleurs une batterie de connecteurs 59 comportant des moyens de connexion automatique avec les connecteurs 19 du chariot 1 et permettant d’assurer au chariot 1 l’arrivée de l’énergie électrique, de l’air comprimé, des fluides, etc. en provenance du véhicule 100. The left part of Figure 2 illustrates an anchoring device 50 which is provided with means for fixing to the floor of the vehicle, inside the reception space 110, and thus forms a carriage guide interface 1, illustrated in the right part of Figure 2, in the completely out of the vehicle position. More particularly, the anchoring equipment 50 comprises several lateral guide elements 51, 52, 53, 54 distributed over the length of the reception space 110 and a crosspiece 55 forming a front stop for the carriage 1. side guides 51, 53 face the guide elements facing each other 52, 54 being spaced apart by a distance substantially equal to the width of the carriage 1. They are each provided with one or more rollers 57 free to rotate around a vertical axis (or perpendicular to the floor of the vehicle) which come into contact with the longitudinal sides 9 of the frame 3 of the carriage 1 and ensure its sliding guidance during its movement in the reception space 110 of the vehicle. In order to allow the movement of the carriage 1, the lower surface (facing the floor of the vehicle) is provided with wheels 10 (fig. 3) by means of which it moves on the floor of the reception space 110. The rollers 10 form the means for moving the carriage 1 inside the vehicle. The movement can be carried out manually by the operator or using an electric cylinder which is actuated to push or pull the carriage. The crosspiece 55 also comprises a battery of connectors 59 comprising means of automatic connection with the connectors 19 of the carriage 1 and making it possible to ensure to the carriage 1 the arrival of electrical energy, compressed air, fluids, etc from vehicle 100.
[0026] La figure 3 illustre par une vue en perspective le chariot 1 en position rentrée dans l’espace de réception d’un véhicule, la partie avant 5a du plateau 2 du chariot étant en butée contre la traverse 55 de l’équipement d’ancrage dans le véhicule, le plateau étant guidé à l’intérieur de celui-ci par les éléments de guidage 51, 52, 53, 54. Les connecteurs automatiques 19 du plateau 2 sont également branchés aux connecteurs 59 de l’équipement d’ancrage pour alimenter le plateau 2 en énergie, etc. Les pieds avant 6a et arrière 6b sont escamotés dans une position de rangement au sein du chariot. Plus précisément, les pieds arrière 6b sont rabattus par une rotation de 180° autour d’un axe de pivotement horizontal situé au niveau du cadre 3 du plateau par rapport à leur position illustrée à la figure 2 dans laquelle ils prennent appui au sol. Ils se trouvent ainsi dans une position verticale et en retrait par rapport à un plan vertical P tangent à l’extrémité arrière 5b du plateau 2 et sont fixés dans cette position. De manière similaire, les pieds avant 6a sont escamotés en position de rangement, par rapport à leur position illustrée à la figure 2, par pivotement de 90° autour d’un axe horizontal porté par le cadre 3, ils se trouvent dans une position horizontale dans un logement prévu à cet effet au sein du plateau 2 et sont fixés dans cette position. Le retour à la position d’appui au sol des pieds avant 6a et arrière 6b, tel qu’illustré à la figure 2, se fait par déblocage des moyens de fixation dans leur position de rangement, pivotement autour les axes de pivotement respectifs et ensuite leur fixation dans la position d’appui au sol à l’aide des brides de fixation 11 (fïg. 2). [0026] Figure 3 illustrates in a perspective view the carriage 1 in the retracted position in the reception space of a vehicle, the front part 5a of the plate 2 of the carriage being in abutment against the crosspiece 55 of the equipment of anchoring in the vehicle, the plate being guided inside the latter by the guide elements 51, 52, 53, 54. The automatic connectors 19 of the plate 2 are also connected to the connectors 59 of the equipment of anchor to supply tray 2 with energy, etc. The front 6a and rear 6b legs are retracted into a storage position within the carriage. More precisely, the rear legs 6b are folded down by a rotation of 180° around a horizontal pivot axis located at the level of the frame 3 of the plate with respect to their position illustrated in FIG. 2 in which they rest on the ground. They are thus in a vertical position and set back with respect to a vertical plane P tangent to the rear end 5b of the plate 2 and are fixed in this position. Similarly, the front feet 6a are retracted into the storage position, relative to their position illustrated in Figure 2, by pivoting 90° about a horizontal axis carried by the frame 3, they are in a horizontal position in a housing provided for this purpose within the plate 2 and are fixed in this position. The return to the position of support on the ground of the front 6a and rear 6b feet, as illustrated in FIG. 2, is done by unlocking the fixing means in their storage position, pivoting around the respective pivot axes and their fixing in the position of support on the ground using the fixing flanges 11 (fig. 2).
[0027] Selon l’invention, et tel que mieux visible aux figures 4 à 6, le chariot 1 comporte des moyens de blocage 30 du chariot en position complètement rentrée dans l’espace de réception 110 du véhicule de transport 100. Plus particulièrement, les moyens de blocage comportent un levier 31 d’actionnement en mouvement d’une butée 40 prévue pour coopérer avec une encoche 41 fixée à l’intérieur dudit espace de réception du véhicule, entre une première position de déblocage du plateau 2 dans laquelle la butée 40 ne coopère pas avec l’encoche 41 et une deuxième position de verrouillage du plateau 2 dans laquelle la butée 40 est insérée à l’intérieur de l’encoche 41. Selon l’invention également, le levier 31 est réalisé de manière à être protubérant par rapport à l’extrémité arrière 5b du plateau 2 en position de déblocage et à s’effacer par rapport à l’extrémité arrière 5b du plateau 2 lorsque ledit levier est en position de verrouillage du plateau 2. According to the invention, and as best seen in Figures 4 to 6, the carriage 1 comprises means 30 for locking the carriage in the fully retracted position in the receiving space 110 of the transport vehicle 100. More particularly, the locking means comprise a lever 31 for actuating in movement a stop 40 provided to cooperate with a notch 41 fixed inside said space for receiving the vehicle, between a first position for unlocking the plate 2 in which the abutment 40 does not cooperate with the notch 41 and a second locking position of the plate 2 in which the abutment 40 is inserted inside the notch 41. According to the invention also, the lever 31 is made in such a way as to protrude with respect to the rear end 5b of the plate 2 in the unlocking position and to disappear with respect to the rear end 5b of the plate 2 when the said lever is in the unlocked position. tray lock 2.
[0028] Tel que mieux visible aux figures 5 et 6, l’encoche 41 est située dans un élément de guidage latéral 52, une encoche similaire étant prévue dans un même but dans l’élément de guidage latéral 51 en vis-à-vis. La butée 40 se situe à l’extrémité d’une tige 42 entraînée en un mouvement de coulissement horizontal par rapport à l’encoche 41 lors de l’actionnement du levier 31. Le levier 31 est relié à une bielle 32 munie d’un pivot central 33, dont Taxe de rotation est monté sur une traverse 38 du plateau 2, et de deux articulations rotatives d’extrémité 34 et 35 reliant chacune la bielle 32 à des bras 36 et 37 qui sont à leur tour articulés à la tige 42 portant la butée 40 mobile. Le bras 36 est plus long que le bras 37, il a une longueur d’environ trois fois supérieure à celle du bras 37. De ce fait, le pivot 33 central se trouve plus proche d’un bord 9 du cadre 3 du plateau que du bord 9 en vis-à-vis de celui-ci. Les articulations 34, 35 et le pivot 33 sont alignés selon Taxe longitudinal de la bielle 32 qui est, elle, alignée selon la direction transversale du plateau 2 en position de blocage (fïg. 5 et 6). As best seen in Figures 5 and 6, the notch 41 is located in a lateral guide element 52, a similar notch being provided for the same purpose in the lateral guide element 51 vis-à-vis . The stop 40 is located at the end of a rod 42 driven in a horizontal sliding movement relative to the notch 41 when the lever 31 is actuated. The lever 31 is connected to a connecting rod 32 provided with a central pivot 33, whose axis of rotation is mounted on a crosspiece 38 of the plate 2, and two rotary end joints 34 and 35 each connecting the connecting rod 32 to arms 36 and 37 which are in turn articulated to the rod 42 carrying the movable stop 40. The arm 36 is longer than the arm 37, it has a length of approximately three times greater than that of the arm 37. As a result, the central pivot 33 is closer to an edge 9 of the frame 3 of the plate than of the edge 9 opposite it. The joints 34, 35 and the pivot 33 are aligned along the longitudinal axis of the connecting rod 32 which is itself aligned along the transverse direction of the plate 2 in the locking position (Fig. 5 and 6).
[0029] L’axe longitudinal du levier 31 passe par le centre de rotation du pivot 33 central et il est incliné par rapport à la direction longitudinale de la bielle 32. Plus particulièrement, Taxe longitudinal du levier passant par le pivot 33 central fait un angle supérieur à 90° avec Taxe passant par les deux articulations 34 et 35 du côté correspondant au sens de déverrouillage du plateau (fïg. 5 et 6). Cette construction de levier incliné couplé à une bielle dont le point de pivotement central est situé plus proche d’un bord latéral que de l’autre, permet au levier 31, lorsqu’il est en position de verrouillage du plateau 2, de venir se positionner dans un logement 39 (fïg. 6) pratiqué dans la bordure du cadre 3 de l’extrémité arrière 5b, juste en dessous de Taxe de pivotement en position dépliée des pieds arrière 6b, ce qui empêche ainsi toute manipulation des pieds arrière 6b. Dans l’exemple illustré le levier 31 et la bielle 32 sont réalisés en une pièce, mais ils peuvent aussi être assemblés à partir de deux pièces différentes. [0030] On peut, bien entendu, dans une variante, que le levier 31 ne passe pas par le pivot 33 central de la bielle 32 tout en assurant la même finalité de sécurité et ceci dans un environnement différent. The longitudinal axis of the lever 31 passes through the center of rotation of the central pivot 33 and it is inclined with respect to the longitudinal direction of the connecting rod 32. More particularly, the longitudinal axis of the lever passing through the central pivot 33 makes a angle greater than 90° with the axis passing through the two joints 34 and 35 on the side corresponding to the direction of unlocking of the plate (fig. 5 and 6). This inclined lever construction coupled to a connecting rod whose central pivot point is located closer to one side edge than the other, allows the lever 31, when it is in the locking position of the plate 2, to come position in a housing 39 (fig. 6) made in the edge of the frame 3 of the rear end 5b, just below the pivot axis in the unfolded position of the rear legs 6b, which thus prevents any manipulation of the rear legs 6b. In the example illustrated the lever 31 and the connecting rod 32 are made in one piece, but they can also be assembled from two different parts. One can, of course, in a variant, that the lever 31 does not pass through the central pivot 33 of the connecting rod 32 while ensuring the same security purpose and this in a different environment.
[0031] On va expliquer dans ce qui suit le fonctionnement du chariot porte-charge mobile de l’invention. Le chariot 1 se trouve initialement à l’extérieur du véhicule de transport afin de pouvoir installer une charge utile, par exemple un atelier, sur son plateau porte-charge. Une fois la charge installée sur le chariot, ce dernier est amené à proximité de la partie arrière d’un véhicule en vue de son introduction dans un espace de réception 110 de celui-ci. L’équipement d’ancrage 50 a été au préalable installé dans l’espace de réception 110. On commence par engager la partie avant 5a du chariot 1 dans l’espace de réception 110, le chariot étant guidé par les éléments latéraux 51, 52 les plus proche de la porte arrière du véhicule. Le chariot est poussé par l’opérateur et roule sur le plancher du véhicule à l’aide des roulettes 10. Dans une variante, le chariot est tracté par un vérin électrique. Lorsque les pieds avant 6a sont proches de l’entrée dans le véhicule, on arrête le déplacement du chariot et on rabat les pieds avant 6a dans la position illustrée à la figure 3. On continue à pousser le chariot jusqu’à ce que les pieds arrière 6b se rapprochent de l’entrée du véhicule. On procède ensuite à l’escamotage des pieds arrière 6b jusqu’à ce qu’ils prennent la position illustrée à la figure 3 et on pousse le chariot jusqu’à ce que son extrémité avant 5a vienne en butée contre la traverse 55. Le chariot est en ce moment en position complètement rentrée dans le véhicule et on procède à son blocage en position à l’aide des moyens de blocage 30. Pour ceci, on actionne le levier 31 qui tire sur la bielle 32 et permet aux butées 40 de passer d’une position de déblocage du plateau 2 illustrée à la figure 4 à une position de blocage ou de verrouillage du plateau 2, illustré à la figure 5, en déplaçant les butées 40 dans des encoches 41 situées dans les éléments latéraux 51 et 52 fixées au plancher du véhicule. Le plateau est ainsi bloqué par rapport au véhicule et le transport de celui-ci peut se faire en toute sécurité. Lors de cette opération de verrouillage du plateau du chariot 1, le levier 31 qui est protubérant dans la position déverrouillée (fïg. 4) par rapport au plan vertical P tangent à l’extrémité arrière 5b du plateau et qui est suffisamment saillant pour empêcher la fermeture des portes du véhicule, se trouve dans une position de verrouillage dans laquelle son extrémité libre 31 ’ est dans un même plan P que l’extrémité arrière 5b du plateau, voire en retrait par rapport à ce plan. Ceci permet la fermeture des portes du véhicule et donc le transport de la charge portée par le chariot de 1’invention. On note par ailleurs, plus particulièrement en référence aux figures 5 et 6 que, lorsque le levier 31 est en position de verrouillage, il empêche le dépliage des pieds arrière 6b, pour encore plus de sécurité. We will explain in what follows the operation of the mobile load carrier of the invention. The carriage 1 is initially located outside the transport vehicle in order to be able to install a payload, for example a workshop, on its load-carrying platform. Once the load has been installed on the trolley, the latter is brought close to the rear part of a vehicle with a view to its introduction into a reception space 110 thereof. The anchoring equipment 50 has been previously installed in the reception space 110. One begins by engaging the front part 5a of the carriage 1 in the reception space 110, the carriage being guided by the side elements 51, 52 closest to the rear door of the vehicle. The carriage is pushed by the operator and rolls on the floor of the vehicle using the rollers 10. Alternatively, the carriage is pulled by an electric jack. When the front feet 6a are close to entering the vehicle, the movement of the carriage is stopped and the front feet 6a are folded down into the position illustrated in FIG. 3. The carriage continues to be pushed until the feet rear 6b approach the entrance to the vehicle. The rear feet 6b are then retracted until they assume the position illustrated in FIG. 3 and the carriage is pushed until its front end 5a comes into abutment against the crosspiece 55. The carriage is currently in the completely retracted position in the vehicle and it is locked in position using the locking means 30. For this, the lever 31 is actuated which pulls on the connecting rod 32 and allows the stops 40 to pass from an unlocking position of the plate 2 illustrated in figure 4 to a blocking or locking position of the plate 2, illustrated in figure 5, by moving the stops 40 in notches 41 located in the side elements 51 and 52 fixed on the floor of the vehicle. The tray is thus locked relative to the vehicle and the transport of the latter can be done in complete safety. During this locking operation of the plate of the carriage 1, the lever 31 which is protruding in the unlocked position (fig. 4) with respect to the vertical plane P tangent to the rear end 5b of the plate and which is sufficiently projecting to prevent the closing the doors of the vehicle, is in a locking position in which its free end 31' is in the same plane P as the rear end 5b of the plate, or even set back with respect to this plane. This allows the closing of the vehicle doors and therefore the transport of the load carried by the trolley of the invention. It is also noted, more particularly with reference to Figures 5 and 6 that, when the lever 31 is in the locking position, it prevents the unfolding of the rear legs 6b, for even more safety.
[0032] D’autres variantes et modes de réalisation de l’invention peuvent être envisagés dans le cadre de l’invention telle que revendiquée. Ainsi, une seule butée mobile peut être associée à un levier d’actionnement des moyens de blocage. [0032] Other variants and embodiments of the invention may be envisaged within the scope of the invention as claimed. Thus, a single movable stop can be associated with an actuation lever of the locking means.
[0033] Par ailleurs, on peut envisager un entraînement motorisé du levier d’actionnement de la butée mobile par rapport à l’encoche fixe. Bien entendu un tel chariot porte-charge peut être introduit dans tout véhicule de transport, à moteur thermique, hybride ou électrique, du moment qu’il est muni d’un espace de réception du chariot adéquat. Furthermore, one can consider a motorized drive of the actuating lever of the movable stop relative to the fixed notch. Of course, such a load-carrying trolley can be introduced into any transport vehicle, with combustion engine, hybrid or electric, as long as it is equipped with an adequate space for receiving the trolley.
