Description

L'invention a trait à l'arrimage d'un chariot élévateur à l'arrière d'un camion.The invention relates to the securing of a forklift to the rear of a truck.

On connaît déjà l'utilisation de deux poutrelles tubulaires qui sont fixées sous le plateau du camion en étant orientées longitudinalement. Ces poutrelles sont prévues pour que la fourche du chariot y soit engagée en positionnant le chariot coaxialement derrière le camion, en levant la fourche à la hauteur convenable, et en faisant avancer le chariot pour que chaque bras horizontal de la fourche s'insère à l'intérieur de l'une des poutrelles. Une fois cette manoeuvre réalisée, la fourche est entraînée à abaissement afin de lever le chariot qui se charge ainsi lui-même sur le camion. L'arrimage est ensuite terminé en utilisant des moyens complémentaires pour assujetir le chariot au camion. Le déchargement se fait de façon similaire, mais en sens inverse.We already know the use of two tubular beams which are fixed under the platform of the truck being oriented longitudinally. These beams are provided so that the fork of the carriage is engaged there by positioning the carriage coaxially behind the truck, lifting the fork to the appropriate height, and advancing the carriage so that each horizontal arm of the fork is inserted at the inside one of the beams. Once this maneuver has been carried out, the fork is driven to lowering in order to lift the carriage which thus loads itself on the truck. The stowage is then completed using additional means to secure the truck to the truck. Unloading is done similarly, but in reverse.

Les camions capables d'embarquer ainsi un chariot élévateur sont particulièrement appréciés, car ils permettent de livrer des marchandises de façon totalement autonome, le chauffeur du camion utilisant le chariot qu'il a transporté pour décharger les marchandises, et pour les amener jusqu'à leur lieu de stockage.The trucks capable of carrying a forklift in this way are particularly appreciated, because they make it possible to deliver goods completely independently, the driver of the truck using the trolley which he has transported to unload the goods, and to bring them to their place of storage.

L'invention vise à simplifier les mesures à prendre pour équiper un camion de moyens d'arrimage d'un chariot élévateur.The invention aims to simplify the measures to be taken to equip a truck with means of securing a forklift.

Elle propose à cet effet un support d'arrimage d'un chariot élévateur à l'arrière d'une plate-forme de camion, comportant deux poutrelles tubulaires orientées longitudinalement prévues pour que la fourche du chariot y soit engagée puis soit entraînée à abaissement afin de lever le chariot qui se charge ainsi lui-même sur le camion, et des moyens complémentaires de soutien du chariot dans une position de chargement, caractérisé en ce qu'il comporte des moyens de fixation sur la plate-forme agissant par pincement d'au moins une membrure en saillie sous la plate-forme, ledit support d'arrimage étant prévu pour être un ensemble amovible.To this end, it provides a support for securing a forklift to the rear of a truck platform, comprising two tubular beams oriented longitudinally so that the fork of the carriage is engaged therein and then is lowered in order to to lift the trolley which thus loads itself on the truck, and additional means for supporting the trolley in a loading position, characterized in that it comprises means for fixing to the platform acting by pinching at least one member projecting under the platform, said lashing support being designed to be a removable assembly.

L'invention propose ainsi que le support d'arrimage se présente sous la forme d'un ensemble préassemblé qui est fixé par simple pincement d'une ou plusieurs membrures en saillie sous la plate-forme.The invention thus proposes that the lashing support is in the form of a pre-assembled assembly which is fixed by simple pinching of one or more members projecting from the platform.

L'installation sur un camion du support d'arrimage selon l'invention est particulièrement aisée vis-à-vis des supports antérieurs qui étaient livrés sous forme de kit constitué par un ensemble de profilés métalliques qu'il fallait retailler en fonction des dimensions du camion à équiper, et assembler par soudure les uns aux autres en construisant le support directement sur le camion.The installation on a truck of the lashing support according to the invention is particularly easy with respect to the previous supports which were delivered in the form of a kit consisting of a set of metal profiles which had to be resized according to the dimensions of the truck to equip, and assemble by welding to each other by building the support directly on the truck.

La fixation par pincement du support selon l'invention lui permet, si on le désire, de rester fixé définitivement sur le camion, mais le caractère aisément démontable de cette fixation permet en fait de considérer le support comme étant amovible, ce qui permet par exemple de le démonter d'un camion qui n'a pas besoin d'embarquer un chariot élévateur, afin de le monter sur un autre camion qui en a besoin, de sorte qu'à l'échelle d'un parc de camions effectuant des types de livraisons diverses, on peut optimiser le nombre de supports d'arrimage nécessaires pour l'ensemble du parc.The clamping attachment of the support according to the invention allows it, if desired, to remain permanently fixed on the truck, but the easily removable nature of this fixing makes it possible in fact to consider the support as being removable, which allows for example to dismantle it from a truck which does not need to board a forklift, in order to mount it on another truck which needs it, so that on the scale of a fleet of trucks performing types of various deliveries, we can optimize the number of lashing supports required for the entire fleet.

Le caractère amovible du support d'arrimage est en outre particulièrement intéressant lorsque la plate-forme du camion est elle-même amovible, et spécialement dans le cas où la plate-forme est adaptée à être chargée ou déchargée d'un camion qui est muni d'un dispositif de manutention tel que décrit dans le brevet français 2.109.109 ou 2.185.520, c'est-à-dire comportant une potence articulée commandée hydrauliquement, munie à son sommet d'un crochet coopérant avec une anse de préhension de la face avant de la plate-forme, et de deux galets disposés à l'arrière du châssis sur lesquels roulent des longerons en saillie sous la plate-forme, lorsqu'elle est chargée ou déchargée. En effet, le support d'arrimage selon l'invention permet de combiner les avantages des plates-formes amovibles, et ceux du chariot élévateur embarqué, puisqu'après avoir chargé la plate-forme, on peut fixer à l'arrière de celle-ci le support d'arrimage selon l'invention, par pincement sur lesdits longerons, et qu'on peut démonter le support d'arrimage avant de décharger la plate-forme.The removable nature of the lashing support is also particularly advantageous when the truck platform is itself removable, and especially in the case where the platform is adapted to be loaded or unloaded from a truck which is provided a handling device as described in French patent 2,109,109 or 2,185,520, that is to say comprising an articulated bracket controlled hydraulically, provided at its top with a hook cooperating with a handle for gripping the front face of the platform, and two rollers arranged at the rear of the chassis on which roll beams projecting under the platform, when loaded or unloaded. Indeed, the lashing support according to the invention makes it possible to combine the advantages of the removable platforms, and those of the on-board forklift, since after having loaded the platform, it is possible to fix at the rear of it ci the lashing support according to the invention, by pinching on said rails, and that the lashing support can be removed before unloading the platform.

Selon des caractéristiques préférées, ladite membrure en saillie sous la plate-forme est un longeron comportant une aile horizontale, les moyens de fixation étant adaptés à serrer le support contre une surface inférieure du longeron en portant sur une surface supérieure de ladite aile horizontale.According to preferred characteristics, said frame projecting under the platform is a spar comprising a horizontal wing, the fixing means being adapted to clamp the support against a lower surface of the spar by bearing on an upper surface of said horizontal wing.

Ces caractéristiques sont en effet favorables à la pereNnité de la fixation par pincement, puisque ce sont essentiellement des efforts situés dans un plan horizontal auquel doit résister le serrage.These characteristics are indeed favorable to the pereNnity of fixing by pinching, since they are essentially forces located in a horizontal plane which the tightening must resist.

De préférence, les moyens de fixation agissent par pincement respectif de deux longerons en regard comportant chacun une aile inférieure horizontale à disposition mutuellement symétrique (c'est-à-dire que les ailes sont toutes deux en saillie du côté interne de leur longeron, ou toutes deux en saillie du côté externe), les moyens de fixation étant adaptés à serrer le support contre la surface inférieure de chaque longeron en portant sur une surface supérieure de chaque dite aile horizontale à disposition mutellement symétrique.Preferably, the fixing means act by respective pinching of two facing side members each comprising a horizontal lower wing with a mutually symmetrical arrangement (that is to say the wings are both projecting from the internal side of their side member, or both projecting from the outer side), the means of fixing being adapted to clamp the support against the lower surface of each spar by bearing on an upper surface of each said horizontal wing with mutually symmetrical arrangement.

Ainsi, au cas où le support se déplacerait transversalement, le bout d'au moins un des éléments par lesquels le support porte sur la surface supérieure de l'aile horizontale va rencontrer l'aile verticale du longeron, et le mouvement transversal sera donc arrêté. Par conséquent, même au cas où un léger desserrage se produirait, le support pourrait simplement coulisser le long du longeron. Dans la pratique, ce coulissement ne risque pas de provoquer la perte par le camion du support et du chariot, les moyens complémentaires d'arrimage prévus entre le chariot et la plate-forme du camion limitant l'amplitude du coulissement possible en cas de desserrage.Thus, in the event that the support moves transversely, the end of at least one of the elements by which the support bears on the upper surface of the horizontal wing will meet the vertical wing of the spar, and the transverse movement will therefore be stopped. . Therefore, even in the event of a slight loosening, the support could simply slide along the spar. In practice, this sliding does not risk causing the truck to lose the support and the carriage, the additional securing means provided between the carriage and the platform of the truck limiting the amplitude of the possible sliding in the event of loosening. .

De préférence, les moyens de fixation comportent deux paires de mécanismes de serrage, chaque paire comportant deux mécanismes opposés disposés respectivement d'un premier et d'un deuxième côté, ayant chacun une patte d'appui adaptée à porter sur ladite aile horizontale à disposition mutellement symétrique, respectivement d'un premier et d'un deuxième desdits longerons en regard.Preferably, the fixing means comprise two pairs of clamping mechanisms, each pair comprising two opposite mechanisms arranged respectively on a first and on a second side, each having a support tab adapted to be carried on said horizontal wing available mutually symmetrical, respectively of a first and a second of said facing beams.

Avec cette disposition des mécanismes de serrage, la répartition des contraintes sur les longerons se fait dans les meilleures conditions, et évite les risques de dépassement accidentel de la charge qu'ils sont capables de supporter, et notamment les efforts dynamiques qui peuvent se produire sur les mauvais chemins du fait des secousses auxquelles est soumis le camion.With this arrangement of the clamping mechanisms, the distribution of the stresses on the beams is done in the best conditions, and avoids the risks of accidental overshoot of the load that they are able to support, and in particular the dynamic forces that can occur bad roads due to the tremors to which the truck is subjected.

Selon d'autres caractéristiques préférées, le support est adapté à reposer sur le sol avec les poutrelles à peu près parallèles au sol de sorte que la fourche du chariot puisse s'y engager, et adapté à être alors mis en place sous la plate-forme du camion grâce au chariot élévateur.According to other preferred characteristics, the support is adapted to rest on the ground with the beams roughly parallel to the ground so that the fork of the carriage can engage there, and adapted to be then put in place under the truck platform thanks to the forklift.

On rend ainsi possible d'exécuter de façon autonome le montage du support d'arrimage sur le camion.This makes it possible to carry out independently the mounting of the lashing support on the truck.

De préférence, afin de faciliter les opérations, le support comporte des moyens de positionnement vis-à-vis de la plate-forme lors de sa mise en place sous celle-ci.Preferably, in order to facilitate the operations, the support includes positioning means with respect to the platform when it is placed under it.

  • the fixing means comprise at least one clamping mechanism comprising: a lug on said upper surface of the horizontal wing of the spar; and a jack comprising a body linked to the support, a rod linked to the support tab, a spring acting on the rod to apply the support tab to said upper surface with a predetermined force, and means for admitting fluid under pressure to apply a force opposite the said predetermined force on the rod in order to control an opening of the clamping mechanism,
  • the complementary means for supporting the carriage comprise, for each front wheel of the carriage, a lower support and a front stop,
  • the support comprises: a front cross member and a rear cross member between said beams; an upright on the outer side of each beam, at the foot of which is said lower support and to which said front stop is connected; and a front leg disposed in the center of the front cross member, having a length adapted so that the support can rest on the ground by the respective bases of said uprights and said leg with the beams roughly parallel to the ground, so that the fork carriage can engage.

Sous un deuxième aspect, l'invention vise un système d'arrimage d'un chariot élévateur à l'arrière d'une plate-forme de camion, caractérisé en ce qu'il comporte un support tel que précédemment exposé, et de chaque côté : un moyen d'ancrage sur la plate-forme, un moyen d'ancrage sur le chariot, et un lien entre lesdits moyens d'ancrage.In a second aspect, the invention relates to a system for securing a forklift to the rear of a truck platform, characterized in that it comprises a support as previously exposed, and on each side : an anchoring means on the platform, an anchoring means on the carriage, and a link between said anchoring means.

De préférence, chaque dit lien comporte un ridoir à vis.Preferably, each said link includes a turnbuckle.

Le lien est ainsi beaucoup plus rigide qui s'il était formé par un câble ou une chaîne, ce qui permet de limiter l'amplitude des soubresauts du chariot lorsque le camion roule sur mauvais chemin, et donc de limiter l'amplitude des contraintes dynamiques exercées par celui-ci.The link is thus much more rigid which, if formed by a cable or a chain, which makes it possible to limit the amplitude of the jolts of the carriage when the truck is traveling on the wrong path, and therefore to limit the amplitude of the dynamic stresses exercised by it.

Sous un troisième aspect, l'invention vise un camion caractérisé en ce qu'il comporte une plate-forme à l'arrière de laquelle est installé un système d'arrimage tel que précédemment exposé, ladite plate-forme étant adaptée à être chargée ou déchargée du camion qui est muni d'un dispositif de manutention comportant une potence articulée commandé hydrauliquement, munie à son sommet d'un crochet coopérant avec une anse de préhension de la plate-forme, et de deux galets disposés à l'arrière du châssis sur lesquels roulent des longerons en saillie sous la plate-forme, lorsqu'elle est chargée ou déchargée, ledit support d'arrimage étant fixé par pincement sur lesdits longerons.In a third aspect, the invention relates to a truck characterized in that it comprises a platform at the rear of which is installed a lashing system as previously exposed, said platform being adapted to be loaded or unloaded from the truck which is provided with a handling device comprising an articulated jib hydraulically controlled, provided at its top with a hook cooperating with a handle for gripping the platform, and with two rollers arranged at the rear of the chassis on which roll beams projecting under the platform, when loaded or unloaded, said lashing support being fixed by pinching on said beams.

De préférence, ladite plate-forme comporte des pièces de coin arrières, sur lesquelles sont fixés lesdits moyens d'ancrage.Preferably, said platform includes rear corner pieces, on which said anchoring means are fixed.

Ces pièces de coin (en anglais "corner fitting"), par exemple du type prévu par une norme ISO, sont en effet particulièrement commodes pour la fixation des moyens d'ancrage sur la plate-forme. En outre, comme on l'a vu, il est particulièrement intéressant sur le plan de la sécurité en cas de desserrage intempestif du support, que les points d'accrochage soient situés sur la plate-forme plutôt que sur le support.These corner pieces (in English "corner fitting"), for example of the type provided by an ISO standard, are in fact particularly convenient for fixing the anchoring means to the platform. In addition, as we have seen, it is particularly advantageous in terms of security in the event of untimely loosening of the support, that the attachment points are located on the platform rather than on the support.

A cet égard, il est avantageux que ledit support comporte des moyens de positionnement latéral vis-à-vis de la plate-forme adaptés à coopérer avec lesdits longerons et des moyens de positionnements longitudinaux adaptés à coopérer avec une surface arrière de la plate-forme.In this regard, it is advantageous that said support comprises means for lateral positioning with respect to the platform adapted to cooperate with said longitudinal members and longitudinal positioning means adapted to cooperate with a rear surface of the platform. .

The description of the invention will now be continued with the description of an exemplary embodiment, given below by way of illustration and not limitation, with reference to the appended drawings in which:
  • Figure 1 is a schematic elevational view, taken from the left, of a truck with a platform at the rear of which is stowed a forklift thanks to a system according to the invention installed on the platform , the latter being adapted to be loaded or unloaded from the truck by means of a hydraulically controlled articulated jib handling device, with which the truck is provided,

  • Figure 5 shows a variant of the clamping mechanism.

Le camion 1 montré sur la figure 1 comporte un dispositif de manutention 2 du type décrit dans le brevet français 2.185.520, comportant une potence 3 articulée à l'arrière autour d'un axe 4 sur un faux-châssis 5 lui-même articulé à l'arrière du châssis du camion autour d'un axe 6, la potence étant commandée hydrauliquement grâce à des vérins 7, et munie à son sommet d'un crochet 8 coopérant avec une anse de préhension (non représentée) située sur la face avant de la plate-forme 9, deux galets 10 étant disposés à l'arrière du châssis du camion pour coopérer chacun avec un longeron 11 en saillie sous la plate-forme 9.The truck 1 shown in FIG. 1 comprises a handling device 2 of the type described in French patent 2,185,520, comprising a bracket 3 articulated at the rear around an axis 4 on a subframe 5 itself articulated at the rear of the truck chassis around an axis 6, the bracket being hydraulically controlled by means of jacks 7, and provided at its top with a hook 8 cooperating with a grip handle (not shown) located on the face front of the platform 9, two rollers 10 being disposed at the rear of the chassis of the truck to cooperate each with a spar 11 projecting under the platform 9.

Pour décharger celle-ci du camion, après avoir déchargé le chariot 12 et démonté son système d'arrimage sur la plate-forme 9 (voir ci-après), le tronçon horizontal de la potence 3, qui est télescopique, est contracté grâce à un vérin non représenté, ce qui fait reculer la plate-forme 9 dont les longerons 11 roulent sur les galets 10, on fait ensuite sortir la tige des vérins 7, ce qui fait basculer la potence 3 en arrière autour de l'axe 4, le mouvement de pivotement de la potence 3 se poursuit jusqu'à ce qu'elle vienne en butée sur le faux-châssis 5, celui-ci et la potence 3 forment alors un ensemble rigide qui pivote autour de l'axe 6, le mouvement se continuant jusqu'à ce que la plate-forme 9 soit entièrement déposée au sol derrière le camion, des rouleaux 13 étant prévus à l'arrière de la plate-forme pour son contact avec le sol. Le chargement d'une plate-forme 9 se fait de manière similaire, mais en sens inverse.To unload it from the truck, after having unloaded the carriage 12 and dismantled its securing system on the platform 9 (see below), the horizontal section of the bracket 3, which is telescopic, is contracted thanks to a jack not shown, which causes the platform 9 to move back, the longitudinal members 11 of which roll on the rollers 10, the rod of the jacks 7 is then brought out, which causes the stem 3 to tilt back around the axis 4, the pivoting movement of the bracket 3 continues until it comes into abutment on the subframe 5, the latter and the bracket 3 then form a rigid assembly which pivots around the axis 6, the movement continuing until the platform 9 is fully deposited on the ground behind the truck, rollers 13 being provided at the rear of the platform for its contact with the ground. The loading of a platform 9 is done in a similar manner, but in reverse.

Le chariot élévateur 12, tout comme le dispositif de manutention 2 et la plate-forme 9, est d'un type bien connu. Il comporte une fourche élévatrice 14 avec deux bras horizontaux 15, montés à coulissement sur un mât vertical 16 en forme de cadre, des moyens d'entraînement de la fourche 14 le long du cadre 16 étant prévus, ainsi que des moyens pour incliner légèrement vers l'arrière le mât 16 en le faisant pivoter autour de l'axe 17. Le mât 16 est monté à coulissement sur des bras horizontaux 18 entre lesquels il est disposé, des moyens d'entraînement étant prévus pour permettre de positionner le mât 16, et donc la fourche 14, entre la position représentée (position reculée maximum) et une position où le mât 16 est situé au niveau de l'extrémité libre des bras 18 (position avancée maximum). Sur le côté extérieur de chaque bras 18, à l'avant, se trouve un roue 19, et au centre, à l'arrière, se trouve une troisième roue 20 qui est montée pivotante autour d'un axe vertical, et qui sert de roue directrice au chariot 12, cette roue 20 étant montrée orientée transversalement au chariot 12, c'est-à-dire dans une configuration où on la met lorsque le chariot est transporté, afin d'éviter qu'elle ne fasse saillie.The forklift 12, like the handling device 2 and the platform 9, is of a well known type. It comprises a lifting fork 14 with two horizontal arms 15, slidably mounted on a vertical mast 16 in the form of a frame, means for driving the fork 14 along the frame 16 being provided, as well as means for tilting the mast 16 slightly backwards by pivoting it around the axis 17. The mast 16 is slidably mounted on horizontal arms 18 between which it is disposed, drive means being provided to enable the mast 16, and therefore the fork 14, to be positioned between the position shown (maximum retracted position) and a position where the mast 16 is located at the free end of the arms 18 (maximum forward position). On the outer side of each arm 18, at the front, is a wheel 19, and in the center, at the rear, is a third wheel 20 which is pivotally mounted around a vertical axis, and which serves as steering wheel to the carriage 12, this wheel 20 being shown oriented transversely to the carriage 12, that is to say in a configuration where it is put when the carriage is transported, in order to prevent it from protruding.

En arrière du mât 16 dans la position reculée maximum, se trouve une cabine 21 où prend place le chauffeur pour piloter le chariot 12, un moteur thermique étant installé dans un compartiment 22 pour entraîner une centrale hydraulique qui alimente les diverses fonctions du chariot, et notamment l'entraînement à coulissement de la fourche 14 le long du mât 16, le pivotement de celui-ci autour de l'axe 17, le coulissement de celui-ci le long des bras 18, et l'entraînement des roues 19 et 20 qui sont chacunes motrices.Behind the mast 16 in the maximum retracted position, there is a cabin 21 where the driver takes place to drive the carriage 12, a heat engine being installed in a compartment 22 to drive a hydraulic unit which supplies the various functions of the carriage, and in particular the sliding drive of the fork 14 along the mast 16, the pivoting thereof around the axis 17, the sliding thereof along the arms 18, and the drive of the wheels 19 and 20 which are each driving force.

Le support d'arrimage du chariot 12 fixé à l'arrière de la plate-forme 9 comporte : deux poutrelles tubulaires 23 orientées longitudinalement dans lesquelles est engagée la fourche 14, chaque bras horizontal 15 étant plus précisément engagé dans une poutrelle 23 ; une traverse avant 24, ici double, et une traverse arrière 25 disposées entre les poutrelles 23 ; un montant 26 du côté extérieur de chaque poutrelle 23 ; un appui inférieur 27, sur lequel repose une roue 19, se trouvant au pied de chaque montant 26, auquel se raccorde également une butée avant 28 pour la roue 19, grâce à une cornière 29 ; et un pied avant 30 disposé au centre de la traverse avant 24 ; et des moyens de fixation sur la plate-forme 9 agissant par pincement des longerons 11.The lashing support of the carriage 12 fixed to the rear of the platform 9 comprises: two tubular beams 23 oriented longitudinally in which the fork 14 is engaged, each horizontal arm 15 being more precisely engaged in a beam 23; a front cross member 24, here double, and a rear cross member 25 disposed between the beams 23; an upright 26 on the outside of each beam 23; a lower support 27, on which rests a wheel 19, located at the foot of each upright 26, to which also connects a front stop 28 for the wheel 19, by means of an angle iron 29; and a front leg 30 disposed in the center of the front cross member 24; and means for fixing to the platform 9 acting by pinching the side members 11.

En outre du support qui vient d'être décrit, le système d'arrimage du chariot 12 à l'arrière de la plate-forme 9 comporte, de chaque côté, un moyen d'ancrage 31 sur la plate-forme 9, un moyen d'ancrage 32 sur le chariot 12 et un lien 33, ici un ridoir à vis.In addition to the support which has just been described, the system for securing the carriage 12 to the rear of the platform 9 comprises, on each side, an anchoring means 31 on the platform 9, a means anchor 32 on the carriage 12 and a link 33, here a turnbuckle.

La plate-forme 9 comporte des pièces de coin 34 conformes à la norme ISO, les moyens d'ancrage 31 y étant fixés d'une façon connue.The platform 9 comprises corner pieces 34 in accordance with the ISO standard, the anchoring means 31 being fixed to it in a known manner.

En position de chargement du chariot 12, les commandes hydrauliques de celui-ci sont relâchées, ce n'est donc pas par l'engagement des bras 15 dans les poutrelles 23 qu'il est maintenu sur le camion, mais parce qu'il est soutenu par ses roues avant grâce à l'appui 27 et à la butée 28, et qu'il est retenu à l'arrière grâce au lien 33.In the loading position of the carriage 12, the hydraulic controls of the latter are released, it is therefore not by the engagement of the arms 15 in the beams 23 that it is maintained on the truck, but because it is supported by its front wheels thanks to the support 27 and the stop 28, and that it is retained at the rear thanks to the link 33.

Pour décharger le chariot, le chauffeur s'installe dans la cabine 21, met en route le moteur, commande la fourche 14 légèrement à l'abaissement, ce qui détend le lien 33 qui peut alors être enlevée, éventuellement après extension, le chauffeur commande le coulissement du mât 16 le long des bras 18 pour l'amener à l'autre extrémité de ceux-ci, de sorte que le chariot, à l'exception de la fourche 14 et du mât 16, recule par rapport au camion, les roues 19 se trouvant en fin de mouvement dans une position où elles ne surplombent plus du tout l'appui inférieur 27, la fourche 14 est commandée à la montée de sorte que le chariot 12 descend jusqu'à ce que ses roues 19 et 20 rencontrent le sol, la roue 20 est orientée longitudinalement, le chariot recule, les bras 15 se dégagent des poutrelles 27 et le chariot finit par être entièrement libéré du système d'arrimage.To unload the carriage, the driver installs himself in the cabin 21, starts the engine, controls the fork 14 slightly downward, which relaxes the link 33 which can then be removed, possibly after extension, the driver controls sliding the mast 16 along the arms 18 to bring it to the other end of the latter, so that the carriage, with the exception of the fork 14 and the mast 16, moves back relative to the truck, the wheels 19 being at the end of movement in a position where they no longer overhang the lower support at all 27, the fork 14 is controlled on ascent so that the carriage 12 descends until its wheels 19 and 20 meet the ground, the wheel 20 is oriented longitudinally, the carriage moves back, the arms 15 are released from the beams 27 and the carriage ends up being entirely freed from the securing system.

Pour charger et arrimer le chariot 12, la procédure est similaire, mais s'effectue bien entendu en sens inverse.To load and stow the carriage 12, the procedure is similar, but is of course carried out in the direction reverse.

On va maintenant décrire plus en détail les moyens de fixation du support d'arrimage sur la plate-forme, qui agissent par pincement des longerons 11, ceux-ci étant formés par un profilé en cornière avec une aile verticale 36 et une aile horizontale 37 (voir figure 4), les deux longerons 11 étant disposés en regard, les ailes horizontales 37 étant toutes deux en saillie du côté interne du longeron.We will now describe in more detail the means for fixing the lashing support to the platform, which act by pinching the side members 11, these being formed by an angle section with a vertical wing 36 and a horizontal wing 37 (see Figure 4), the two side members 11 being arranged opposite, the horizontal wings 37 both projecting from the internal side of the side member.

Les moyens de fixation comportent deux paires de mécanismes de serrage 35, une à l'avant et l'autre à l'arrière, qui sont adaptées à serrer le support d'arrimage contre la surface inférieure 38 de chacun des longerons 11, en portant la surface supérieure 39 de chacune des ailes horizontales 37.The fixing means comprise two pairs of clamping mechanisms 35, one at the front and the other at the rear, which are adapted to clamp the lashing support against the lower surface 38 of each of the side members 11, by carrying the upper surface 39 of each of the horizontal wings 37.

Chaque paire de mécanismes de serrage 35 comporte deux mécanismes opposés disposés respectivement à droite et à gauche, ayant chacun une patte d'appui 40 adaptée à porter sur l'aile horizontale 37 respective du longeron de droite et du longeron de gauche.Each pair of clamping mechanisms 35 comprises two opposite mechanisms disposed respectively on the right and on the left, each having a support lug 40 adapted to bear on the respective horizontal flange 37 of the right side member and the left side member.

Les mécanismes de serrage 35 ont une constitution qui rappelle celle d'un serre-joint. En outre de la patte d'appui 40, ils comportent chacun : une tige verticale 41 fixée à la patte 40, ici par soudure, un guide tubulaire 43 fixé sur le support, ici sur un flanc latéral d'une poutrelle 23, la tige 41 étant engagée dans le guide 43 ; une contre-patte 44 fixée sur la tige 41 à l'opposé de la patte 40, présentant un alésage taraudé transversal 45 ; une vis verticale 46 engagée dans l'alésage 45 avec des trous transversaux 47 et 48 à une extrémité, servant de moyens de prise pour une tige de manoeuvre de la vis, tandis qu'à l'autre extrémité est prévue une semelle d'appui 49 sur un élément du support, ici sur la face inférieure d'une poutrelle 23 ; et un contre-écrou 50 engagé sur la vis 46 entre la contre-patte 44 et l'extrémité où sont pratiqués les trous 47 et 48.The clamping mechanisms 35 have a constitution which recalls that of a clamp. In addition to the support lug 40, they each comprise: a vertical rod 41 fixed to the lug 40, here by welding, a tubular guide 43 fixed to the support, here on a lateral flank of a beam 23, the rod 41 being engaged in the guide 43; a lug 44 fixed to the rod 41 opposite the lug 40, having a transverse threaded bore 45; a vertical screw 46 engaged in the bore 45 with transverse holes 47 and 48 at one end, serving as gripping means for a rod for operating the screw, while at the other end is provided a support sole 49 on an element of the support, here on the underside of a beam 23; and a lock nut 50 engaged on the screw 46 between the lug 44 and the end where the holes 47 and 48 are made.

Pour démonter le support installé sur la plate-forme 9, on engage la fourche 14 dans les poutrelles 23, on débloque les contre-écrous 50, on deserre les vis 46, ce qui a pour conséquence que le support est progressivement soutenu par la fourche 14 et non plus par la plate-forme 9, on fait pivoter le mécanisme 35 (sauf le guide 43) autour de l'axe du guide 43, et on peut alors abaisser la fourche du chariot 12, jusqu'à poser au sol le support, celui-ci y reposant par les bases respectives des montants 26 et du pied 30, celui-ci ayant une longueur adaptée à ce que les poutrelles 23 soient alors à peu près parallèles au sol, de sorte qu'on peut dégager la fourche 14 en faisant reculer le chariot 12.To dismantle the support installed on the platform 9, the fork 14 is engaged in the beams 23, the locknuts 50 are released, the screws 46 are loosened, which means that the support is gradually supported by the fork 14 and no longer by the platform 9, the mechanism 35 is pivoted (except the guide 43) around the axis of the guide 43, and the fork of the carriage 12 can then be lowered, until the ground is placed on the ground. support, the latter resting there by the respective bases of the uprights 26 and of the foot 30, the latter having a length adapted so that the beams 23 are then approximately parallel to the ground, so that the fork can be released 14 by reversing the carriage 12.

De même, lorsqu'on veut monter sur une plate-forme un support stocké au sol, on engage la fourche 14 dans les poutrelles 23, on transporte le support jusqu'à l'arrière du camion, on le met en place sous la plate-forme 9, on fait pivoter les mécanismes 35 de façon à disposer les pattes 40 en regard des ailes 37 et les semelles 49 en regard des poutrelles 23, on serre la vis 46, et on bloque le contre-écrou 50.Similarly, when you want to mount on a platform a support stored on the ground, you engage the fork 14 in the beams 23, you transport the support to the back of the truck, you put it under the platform -form 9, the mechanisms 35 are pivoted so as to arrange the legs 40 facing the wings 37 and the flanges 49 facing the beams 23, the screw 46 is tightened, and the lock nut 50 is blocked.

Afin de faciliter sa mise en place sous la plate-forme, le support comporte des moyens de positionnement, ici deux guides latéraux inclinés opposés 51 adaptés à coopérer respectivement avec le longeron droit et le longeron gauche, et des butées longitudinales arrière 52, adaptées à coopérer avec une surface arrière de la plate-forme 9.In order to facilitate its positioning under the platform, the support comprises positioning means, here two opposite inclined lateral guides 51 adapted to cooperate respectively with the right spar and the left spar, and rear longitudinal stops 52, adapted to cooperate with a rear surface of the platform 9.

On observera que grâce aux moyens de positionnement 52 et au lien 33, le support et le chariot ne pourraient coulisser que de façon modérée vis-à-vis de la plate-forme 9, de sorte que la sécurité de l'arrimage est assurée, même en cas de desserrage des mécanismes 35.It will be observed that thanks to the positioning means 52 and to the link 33, the support and the carriage could only slide moderately with respect to the platform 9, so that the security of the stowage is ensured, even if the mechanisms are loosened 35.

Dans la variante 35' de ces derniers montrée sur la figure 5, la patte d'appui 40' sur l'aile horizontale 37 est liée à la tige 55 d'un vérin 56 qui comporte en outre un corps 57 lié au support de la même manière que le guide 43, un ressort (non représenté) agissant sur la tige 55 pour appliquer avec une force suffisante la patte d'appui 40' sur la surface 39, et un raccord 58 d'admission de fluide sous pression pour appliquer sur la tige 55 une force opposée à celle qu'exerce le ressort afin de commander l'ouverture du mécanisme de serrage. Afin de permettre la mise en place et le démontage, la patte 40' est montée à rotation sur la tige 55.In the variant 35 'of the latter shown in FIG. 5, the support tab 40' on the horizontal wing 37 is linked to the rod 55 of a jack 56 which further comprises a body 57 linked to the support of the same as guide 43, a spring (not shown) acting on the rod 55 to apply with sufficient force the support tab 40 'on the surface 39, and a connector 58 for admission of pressurized fluid to apply on the rod 55 a force opposite to that exerted by the spring in order to control the opening of the clamping mechanism. In order to allow installation and dismantling, the tab 40 ′ is rotatably mounted on the rod 55.

Le support selon l'invention est susceptible d'être fixé sur toute sorte de plate-forme de camions, par exemple une plate-forme avec des longerons en cornière où les ailes horizontales sont toutes deux disposées du côté extérieur des longerons (et non du côté intérieur comme dans l'exemple qui vient d'être décrit), les longerons peuvent être faits dans un profilé autre qu'une cornière, par exemple un profilé en I, et plus généralement le support peut être fixé par pincement d'une ou plusieurs membrures en saillie sous la plate-forme.The support according to the invention is capable of being fixed on any kind of truck platform, for example a platform with angle beams where the horizontal wings are both arranged on the outside of the beams (and not of the inner side as in the example which has just been described), the side members can be made in a profile other than an angle, for example an I-profile, and more generally the support can be fixed by pinching one or several members projecting under the platform.

On notera que le support d'arrimage peut être fixé sur une plate-forme de camion qui n'est pas amovible, et que le support peut comporter en outre des poutrelles 23, des moyens complémentaires de soutien du chariot qui peuvent être différents de l'appui inférieur 27 et de la butée avant 28.It will be noted that the lashing support can be fixed on a truck platform which is not removable, and that the support can further comprise beams 23, complementary means for supporting the carriage which may be different from the lower support 27 and the front stop 28.

On rappelle que l'invention n'est pas limitée aux exemples décrits.It will be recalled that the invention is not limited to the examples described.
