Description
La présente invention a pour objet un chariot élévateur apte à être transporté par un véhicule de transport du type camion remorque ou semi-remorque en étant fixé au châssis de celui-ci.The present invention relates to a forklift capable of being transported by a trailer truck transport vehicle or semi-trailer by being fixed to the chassis thereof.
Dans le domaine du transport, les opérations de chargement et de déchargement d'un véhicule du type camion remorque ou semi-remorque sont réalisées aisément lorsque ledit véhicule est à quai au moyen d'un tire-palette, un chariot élévateur ou analogue. Il en va tout autrement en absence de quai, ce qui est très fréquent lorsque les destinataires des livraisons sont en ville par exemple.In the transport sector, loading and unloading of a trailer or semi-trailer vehicle are easily achieved when said vehicle is docked using of a pallet puller, a forklift or the like. It all goes away otherwise in the absence of a dock, which is very common when recipients of deliveries are in town for example.
Aussi, pour pallier cet inconvénient, il est fréquent d'équiper un véhicule de transport d'un tire-palette qui reste à demeure sur le plateau dudit véhicule pour uniquement déplacer la marchandise sur ledit plateau, et/ou d'un chariot élévateur permettant de descendre la marchandise dudit plateau et de la transférer.Also, to overcome this drawback, it is common to equip a transport vehicle of a pallet puller which remains permanently on the tray of said vehicle to only move the goods on said tray, and / or a forklift allowing to descend the goods from said tray and transfer it.
Cependant, peu de véhicules de transport sont équipés de rampes permettant de faire monter un chariot élévateur sur le plateau, aussi il a été proposé des dispositifs d'accrochage extérieurs permettant de fixer un chariot élévateur à l'arrière d'un véhicule.However, few transport vehicles are fitted with ramps allowing a forklift to be mounted on the platform, also external hanging devices have been proposed for attaching a forklift to the rear of a vehicle.
De tels dispositifs d'accrochage sont décrits dans les documents FR 2.298.454, US 429.357 et EP 0.643.009, ils comportent deux glissières parallèles solidarisées au châssis du véhicule, et destinées à loger la fourche du chariot élévateur, l'actionnement de la fourche dans le sens de la descente permettant de soulever ledit chariot élévateur du sol, tandis que des moyens de bridage permettent de solidariser ledit chariot élévateur au châssis dudit véhicule.Such attachment devices are described in the documents FR 2.298.454, US 429.357 and EP 0.643.009, they include two parallel runners secured to the chassis of the vehicle, and intended to accommodate the fork of the forklift, the actuation of the fork in the direction of descent for lifting said forklift from the ground, while clamping means used to secure said forklift to the chassis of said vehicle.
Si ces dispositifs sont d'une conception simple et d'un maniement aisé, ils n'en présentent pas moins un inconvénient majeur, celui de contrevenir au code de la route, puisqu'un véhicule ainsi équipé dépasse la longueur hors-tout autorisée. En fait, les utilisateurs qui ne souhaitent contrevenir à ce code de la route, n'ont, alors, d'autre solution que de recouper le châssis standard de leur véhicule, d'où découle, inévitablement, une perte de surface utile pour le chargement.If these devices are of simple design and handling easy, they nevertheless have a major drawback, that of traffic violation, since a vehicle so equipped exceeds the overall length allowed. In fact, users who do not wish to contravene this traffic code, do not, then, other solution than to cut the standard chassis of their vehicle, which inevitably results in a loss of useful area for loading.
On connaít également des chariots élévateurs susceptibles d'être repliés pour en permettre un transport aisé, c'est par exemple celui proposé par le document FR 2.628.087. Toutefois le chariot élévateur décrit dans ce document est avant tout conçu pour que la charge ne soit jamais en position de porte-à-faux, en sorte que, du fait de sa conception particulière, son encombrement lorsqu'il est replié est tel qu'il est difficilement manoeuvrable, il ne permet pas en tous cas une solidarisation aisée au châssis d'un véhicule de transport.We also know forklifts likely to be folded down for easy transport, for example proposed by document FR 2.628.087. However the forklift described in this document is primarily designed so that the load does not is never in a cantilever position, so that, due to its special design, its size when folded is as it is difficult to maneuver, it does not allow in all case easy attachment to the chassis of a transport vehicle.
Pour pallier cet inconvénient, il a été proposé dans les documents EP 0.250.018 et GB 2.014.946, des chariots élévateurs comportant un mât sur lequel peut se déplacer une fourche, et où ladite fourche est repliable sur ledit mât, lui-même repliable sur le châssis du chariot, en sorte que lesdits chariots élévateurs soient aptes à être transportés sous le châssis d'un véhicule de transport du type camion.To overcome this drawback, it has been proposed in the documents EP 0.250.018 and GB 2.014.946, forklifts comprising a mast on which a fork can move, and where said fork is foldable on said mast, itself foldable on the chassis of the carriage, so that said forklifts are suitable for be transported under the chassis of a transport vehicle of the type truck.
Cependant, le chariot élévateur proposé dans le document EP 0.250.018 présente également des inconvénients, du fait notamment de sa conception très rudimentaire. En effet, après repliement de la fourche et du mât sur le châssis, l'ensemble est placé transversalement sous le châssis du véhicule de transport, roulé sur deux rails suspendus sous ce dernier. Or la hauteur du chariot élévateur replié demeure importante, en sorte que la plupart des véhicules de transport ne sont pas aptes à être équipés d'un tel chariot élévateur.However, the forklift proposed in document EP 0.250.018 also has drawbacks, in particular due to its very rudimentary design. Indeed, after folding the fork and mast on the chassis, the assembly is placed transversely under the chassis of the transport vehicle, rolled on two rails suspended under the latter. Or the height of the carriage folded elevator remains important, so most transport vehicles are not suitable for being fitted with such a forklift.
Le chariot élévateur du document GB 2.014.946 permet de remédier partiellement à cet inconvénient, le mât est en effet solidarisé au châssis par l'intermédiaire d'un parallélogramme déformable, en sorte qu'après accrochage du mât horizontalement sous le véhicule transport, il est possible de positionner ledit châssis au même niveau que ledit mât, escamotant ainsi la roue directionnelle d'entraínement, les autres roues demeurant toutefois saillantes. Par ailleurs le chariot élévateur proposé dans ce document présente l'inconvénient d'une conception complexe qui est susceptible de nuire à sa robustesse, qui limite ainsi son emploi.The forklift of GB 2.014.946 allows to remedy partially to this drawback, the mast is indeed secured to the chassis via a deformable parallelogram, in so that after hanging the mast horizontally under the vehicle transport, it is possible to position said chassis at the same level as said mast, thus retracting the directional wheel drive, the other wheels however projecting. Through elsewhere the forklift proposed in this document presents the downside of a complex design that is likely to affect its robustness, which limits its use.
La présente invention a pour but de proposer un chariot élévateur apte à être transporté par un véhicule de transport du type camion remorque ou semi-remorque en étant fixé sous le châssis de celui-ci, et permettant de remédier aux divers inconvénients précités.The present invention aims to provide a forklift able to be transported by a transport vehicle of the truck type trailer or semi-trailer while being fixed under the chassis thereof, and making it possible to remedy the various aforementioned drawbacks.
Le chariot élévateur objet de la présente invention comporte un châssis présentant une base portée par des roues ou des petites chenilles, dont l'une au moins est directionnelle, un mât le long duquel peut se déplacer, sous l'action d'un ensemble de motorisation porté par ledit châssis, une fourche sensiblement perpendiculaire audit mât, ladite fourche étant repliable contre ledit mât, lequel est repliable contre ladite base pour pouvoir être logé sous le châssis d'un véhicule de transport, lequel est muni de moyens permettant d'y maintenir ledit châssis, et il se caractérise essentiellement en ce qu'il comporte des moyens permettant de déplacer verticalement lesdites roues ou les petites chenilles par rapport audit châssis, en sorte qu'elles puissent être escamotées au-dessus du plan inférieur de la base du châssis.The forklift object of the present invention comprises a chassis with a base carried by wheels or small tracks, at least one of which is directional, a mast along which can move, under the action of a motorization assembly carried by said chassis, a substantially perpendicular fork to said mast, said fork being foldable against said mast, which is foldable against said base so that it can be accommodated under the chassis of a transport vehicle, which is provided with means allowing to maintain said chassis there, and it is characterized essentially in that it includes means for vertically move said wheels or small tracks by report to said chassis, so that they can be retracted above the lower plane of the chassis base.
Selon une autre caractéristique additionnelle du chariot élévateur selon l'invention, le déplacement de chacune des roues est réalisé au moyen d'un vérin hydraulique indépendant.According to another additional characteristic of the forklift according to the invention, the displacement of each of the wheels is carried out by means of an independent hydraulic cylinder.
Selon une autre caractéristique additionnelle du chariot élévateur selon l'invention, les roues non directionnelles sont chacune montées dans une chape apte à pivoter, par l'intermédiaire d'un pivot transversal, sur la base du châssis et sous l'action d'un vérin reliant ladite chape audit châssis de manière excentrée par rapport audit pivot.According to another additional characteristic of the forklift according to the invention, the non-directional wheels are each mounted in a yoke suitable for pivoting, by means of a transverse pivot, on the base of the chassis and under the action of a cylinder connecting said yoke to said chassis eccentrically by report to said pivot.
Selon une autre caractéristique avantageuse du chariot élévateur selon l'invention, la fourche comprend un élément monté coulissant sur le mât, à la base duquel une articulation porte deux dents, ladite articulation permettant auxdites dents de décrire un angle de 90° pour prendre deux positions extrêmes, à savoir perpendiculaire audit élément, et parallèle à celui-ci.According to another advantageous characteristic of the forklift according to the invention, the fork comprises a sliding mounted element on the mast, at the base of which a joint carries two teeth, said articulation allowing said teeth to describe an angle of 90 ° to take two extreme positions, namely perpendicular said element, and parallel to it.
Selon une autre caractéristique avantageuse du chariot élévateur selon l'invention, son châssis comporte extérieurement et latéralement deux cornières destinées, après le repliement du mât, à prendre place sur des glissières parallèles que comporte inférieurement et transversalement le châssis du véhicule.According to another advantageous characteristic of the forklift according to the invention, its chassis comprises externally and laterally two angles intended, after the folding of the mast, to take place on parallel slides that includes below and transversely the chassis of the vehicle.
Selon un mode de réalisation préférentiel du chariot élévateur selon l'invention, la base du châssis est en forme de U, c'est-à-dire qu'elle présente deux bras parallèles reliés par une traverse, lesdits bras comportant chacun une roue, tandis que ladite traverse porte l'ensemble de motorisation et repose sur une roue orientable.According to a preferred embodiment of the forklift according to the invention, the base of the chassis is U-shaped, that is to say that it has two parallel arms connected by a cross member, said arms each comprising a wheel, while said cross member carries the power unit and rests on a steerable wheel.
Selon une caractéristique avantageuse du chariot élévateur selon l'invention, le mât est solidarisé à la traverse de la base du châssis par l'intermédiaire d'une articulation lui permettant de prendre deux positions extrêmes, à savoir parallèle aux bras de ladite base, et perpendiculaire au plan défini lesdits bras.According to an advantageous characteristic of the forklift according to the invention, the mast is secured to the cross member of the base of the chassis through a hinge allowing it to take two extreme positions, namely parallel to the arms of said base, and perpendicular to the plane defined said arms.
Une telle articulation permet encore à l'ensemble de levage de coulisser latéralement par rapport au châssis par l'intermédiaire, notamment, d'un vérin placé horizontalement, ceci en vue de faciliter le positionnement de palettes sur ledit véhicule de transport.Such a joint still allows the lifting assembly to slide laterally with respect to the chassis via, in particular, a jack placed horizontally, this for facilitate the positioning of pallets on said vehicle transport.
Selon une autre caractéristique additionnelle du chariot élévateur selon l'invention, la traverse de la base du châssis est constituée de deux profilés aptes à coulisser l'un dans l'autre, ou l'un contre l'autre.According to another additional characteristic of the forklift according to the invention, the cross member of the base of the chassis consists two profiles capable of sliding one inside the other, or one against the other.
Le chariot élévateur est ainsi de largeur variable, ce qui permet de lui réserver, sous le châssis du véhicule de transport, un emplacement très réduit, et lorsqu'il est déployé, d'accroítre sa largeur et donc sa stabilité.The forklift is thus of variable width, which allows reserve, under the chassis of the transport vehicle, a very small location, and when deployed, to increase its width and therefore its stability.
Selon une autre caractéristique additionnelle du chariot élévateur selon l'invention, le mât est monté coulissant le long de la traverse de la base du châssis.According to another additional characteristic of the forklift according to the invention, the mast is slidably mounted along the cross member from the base of the chassis.
De manière avantageuse, le châssis comporte des moyens permettant de bloquer le mât en position verticale après son redressement et son déplacement le long de la traverse de la base dudit châssis.Advantageously, the chassis comprises means making it possible to block the mast in an upright position after its straightening and displacement along the cross member of the base of said chassis.
Les avantages et les caractéristiques du chariot élévateur selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif.The advantages and characteristics of the forklift according to the invention will emerge more clearly from the description which follows and which relates to the attached drawing, which represents a mode of non-limiting realization.

En référence aux figures 1 et 2, on peut voir un chariot élévateur 1
selon l'invention. Il comporte un châssis 2 comprenant une base 20
en forme de U, c'est-à-dire comportant deux bras 21 reliés par une
traverse 22.Referring to Figures 1 and 2, we can see a
Sur une entretoise 23, préférentiellement de forme tubulaire ronde,
parallèle à la traverse 22 et s'entendant entre les bras 21,
s'articule par son extrémité inférieure un mât 24 susceptible de
prendre deux positions extrêmes, à savoir verticale,
perpendiculairement au plan défini par les bras 21, et, représentée
en traits discontinus sur la figure 1, horizontale, parallèlement
audit plan.On a spacer 23, preferably of round tubular shape,
parallel to the
Le manoeuvrement du mât 24 d'une position à une autre peut être
réalisé manuellement, il est toutefois prévu une assistance
hydraulique, qui en outre permet d'assurer un blocage en position,
cette assistance consiste en un vérin 25, visible sur la figure 1,
et reliant le mât 24 à une partie du châssis 2.Maneuvering the
D'autre part, une fourche 3 peut se déplacer le long du mât 24 par
l'intermédiaire d'un moyen classique connu en soi, non représenté,
du type chaíne mue hydrauliquement. La fourche 3 comporte ainsi un
élément 30 monté coulissant sur le mât 24 et à la base duquel deux
dents 31 sont montées pivotantes selon un angle limité à 90°, sur un
pivot 32, entre une position parallèle au mât 24, représentée en
traits discontinus sur la figure 1, et une position perpendiculaire
au mât 24.On the other hand, a
Le châssis 2 est porté par trois roues, une roue 25 à l'extrémité de
chacun des bras 21, et une roue 26 solidaire d'un bras 27 de
manoeuvrement orientable par pivotement sur le châssis 20 selon un
axe vertical. A noter qu'en lieu et place des roues peuvent être
prévues des petites chenilles. De plus, la roue 26 ou la chenille
pivotante peut, avantageusement, être manoeuvrée depuis un poste de
conduite comprenant un siège et un volant.The
Le chariot élévateur 1 tel que décrit précédemment est utilisable de
la même manière qu'un chariot élévateur classique, il permet ainsi
de saisir une charge par les dents 31 de la fourche 3, de soulever
et d'abaisser cette charge le long du mât 24, et de la transférer en
faisant rouler le chariot élévateur 1 sur ses roues 25 et 26 tout en
le dirigeant par le pivotement de la roue 26.The
Le déplacement de la fourche 3 le long du mât 24 et l'alimentation
du vérin 25 sont réalisés au moyen d'un ensemble de motorisation 10,
visible sur la figure 5, comprenant une pompe hydraulique mue par un
moteur thermique ou électrique, ou par air comprimé, visibles.The displacement of the
Dans une variante, non représentée, la traverse 22 est constituée de
deux profilés montés coulissants l'un dans l'autre, ou l'un contre
l'autre, en sorte que les deux bras 21 puissent être écartés ou
rapprochés l'un de l'autre. Lorsque les bras 21 sont rapprochés, le
chariot 1 est très étroit et il est possible de le loger dans un
espace réduit. Inversement, l'écartement des bras 21 et donc des
roues 25, augmente la stabilité du chariot élévateur 1. D'autre
part, de manière à pouvoir centrer le mât 24 en fonction de la
variation de la largeur du chariot élévateur, il peut être déplacé,
par coulissement le long de la traverse 22, par exemple. De plus, le
chariot élévateur 1, ou plus exactement la traverse 22 ou l'un des
deux profilés qui composent celle-ci, comporte des moyens de blocage
permettant, après écartement des bras 21 et redressement du mât 24,
le coulissement de ce dernier sur la traverse 22, puis son maintien
en position verticale, lesdits moyens de blocage pouvant consister
en des profilés parallèles à la traverse 22, entre lesquels peut
glisser le mât 24 dressé verticalement.In a variant, not shown, the
Si on se réfère maintenant aux figures 3 et 4, on peut voir que les
roues 25, qui sont non directionnelles et dont une seule est
visible, sont chacune montées dans une chape 4 apte à pivoter à
l'extrémité du bras 21 sur un pivot transversal 40, sous l'action
d'un vérin 41 reliant la chape 4 au bras 21, de manière à faire
varier la position de la roue 25 par rapport au plan défini par les
bras 21.If we now refer to Figures 3 and 4, we can see that the
Par ailleurs, la roue 26 est également reliée au châssis 2 par
l'intermédiaire d'un vérin 28 d'axe perpendiculaire au plan défini
par les bras 21, permettant également de faire varier la position de
la roue 26 par rapport audit plan.Furthermore, the
Aussi, comme on peut le voir sur la figure 4, lorsque le mât 24 est
replié, les vérins 41 et 28 permettent d'escamoter les roues 25 et
26 au-dessus du plan inférieur de la base 20 du châssis 2, de
manière à réduire la hauteur du chariot élévateur 1.Also, as can be seen in Figure 4, when the
On notera qu'en utilisation du chariot élévateur 1 pour charger ou
décharger, l'actionnement des vérins 41 et 28 permet de faire varier
sa garde au sol. Ainsi les figures 3 et 4 représentent les deux
positions extrêmes que peuvent prendre les roues 25 et 26, toutes
les positions intermédiaires étant réalisables.Note that when using the
En outre, les vérins 41 et 28 sont avantageusement indépendants, en
sorte que cela permet en jouant sur la rentrée de l'un par rapport à
la sortie de l'un ou des autres, et inversement, de déplacer le
chariot élévateur dans un dévers tout en maintenant la charge
