Abstract

The lifting platform 11 is carried so that it can tilt by the movable framework 8 associated with the lifting mechanism 15-16-17-18 so as to tip its charge out when the spring bolt 13 is manipulated, the tilting movement being braked by the gas thruster 12 which furthermore provides the elastic return of the platform to the horizontal position.

Description

La présente invention a trait aux chariots de manutention dans les quels Le chassis, suoDorté par des roues aporopriées, est agencé pour former guide pour un plateau mobile associé à un mécanisme d'élévation, par exemple du type à chaine et à manivelle. The present invention relates to handling carts in which the chassis, supported by aporopriated wheels, is arranged to form a guide for a movable plate associated with an elevation mechanism, for example of the chain and crank type.

Les perfectionnements qui font L'objet de la présente invention ont plus spécialement pour but de simDlifier la manoeuvre de l'engin, tout particulièrement en vue du chargement de colis ou autres à L'intérieur des coffres des véhicules automobiles. The improvements which are the object of the present invention more specifically aim to simplify the maneuvering of the machine, especially with a view to loading packages or the like inside the trunks of motor vehicles.

L'invention consiste essentiellement à monter le plateau élévateur à basculement sur un bâti mobile lié au mécanisme d'élévation et à lui associer d'une part des moyens de verrouillage proDres à le retenir à La position horizontale, d'autre part des moyens de récuoération aptes à freiner le basculement du plateau et à ramener élastiquement celui-ci a
La position verrouillée.The invention essentially consists in mounting the tilting lifting platform on a movable frame linked to the lifting mechanism and in associating therewith on the one hand locking means suitable for retaining it in the horizontal position, on the other hand means for recuperation capable of slowing the tilting of the plate and of resiliently bringing it back to
The locked position.

Le dessin annexé, donné à titre d'exemple, permettra ae mieux comprendre L'invention, Les caractéristiques au'elle présente et les avantages qu'elle est susceptible de procurer
Fig. 1 est une vue en Derspective montrant un chariot de manutention établi conformement à la présente invention.The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is likely to provide.
Fig. 1 is a perspective view showing a handling trolley established in accordance with the present invention.

Fig. 2 représente de la même manière le bâti mobile et le plateau basculant à L'état démonté. Fig. 2 shows in the same way the mobile frame and the tilting plate in the disassembled state.

En fig. 1, la référence 1 désigne Le chassie du chariot, équipe de deux trains de roues avant 2 et de deux roues carrière orientables 3, ces dernières étant supportées par des goussets 4. Ces goussets 4 sont fixés à la base de deux montants 5 solidaires du cassis 1 et pourvus de ooignées de manoeuvre 6 tournées vers l'arriere. Les montants 5 sont réunis L'un à L'autre vers le bas par une traverse du châssis 1, vers le haut par un fer horizontal 7. In fig. 1, the reference 1 designates the carriage carriage, equipped with two sets of front wheels 2 and two steerable career wheels 3, the latter being supported by gussets 4. These gussets 4 are fixed to the base of two uprights 5 integral with the blackcurrant 1 and provided with maneuvering handles 6 facing backwards. The uprights 5 are joined one to the other down by a cross member of the chassis 1, upwards by a horizontal iron 7.

Chacun des montants 5 est formé par un profilé à section en forme de C, les deux profiles s'ouvrant en vis-à-vis afin de constituer guides pour le déplacement d'un bati mobile 8 représenté à la position démontée en fig. 2. Each of the uprights 5 is formed by a section with a C-shaped section, the two profiles opening opposite so as to constitute guides for the movement of a movable frame 8 shown in the disassembled position in FIG. 2.

Ce bâti 8 se présente sous la forme d'un quadrilatère orienté verticalement, les extrémités des barres horizontales étant pourvues de galets 9 agencés pour rouler à jeu réduit à L'intérieur des montants 5. This frame 8 is in the form of a vertically oriented quadrilateral, the ends of the horizontal bars being provided with rollers 9 arranged to roll with reduced clearance inside the uprights 5.

Vers le bas, Le bâti 8 comporte deux prolongements horizontaux ou consoles 8a qui s'étendent vers L'avant du chariot pour porter en bout deux chapes oscillantes 10 fixées contre La face inférieure d'un plateau 11 à profil en forme d'équerre, qui est ainsi apte à basculer par rapport audit bâti 8.Downwards, the frame 8 comprises two horizontal extensions or consoles 8a which extend towards the front of the carriage to carry at the end two oscillating yokes 10 fixed against the underside of a plate 11 with a profile in the form of a square, which is thus able to tilt relative to said frame 8.

Ce plateau 11 est par ailleurs relié au bâti 8 par un vérin à gaz 12 dont un élément est articulé au fond dudit plateau tandis que L'autre est attelé à la barré supérieure du bati. Le blocage du plateau basculant 11 à la position pour Laquelle son aile inférieure est orientée horizontalement est assuré à L'aide d'un verrou à ressort 13 coopérant avec une patte perforée 14 fixée au fond du plateau. This plate 11 is also connected to the frame 8 by a gas spring 12, one element of which is articulated at the bottom of said plate while the other is coupled to the upper crossbar of the frame. The locking of the tilting plate 11 in the position for which its lower wing is oriented horizontally is ensured by means of a spring lock 13 cooperating with a perforated tab 14 fixed to the bottom of the plate.

Le déplacement vertical du bâti 8 et du plateau 11 qu'il supporte à basculement est opéré à l'aide d'une manivelle supérieure 15 (fig. 1) calée sur un petit arbre sur lequel est fixée une roue dentée 16 reliée par une chaine verticale 17 à une roue dentée inférieure 18 portée par la traverse arrière du châssis 1. Les extrémités de cette chaine 17 sont réunies L'une à L'autre par une attache 19 rendue solidaire de la barre inférieure du bâti 8. On observera qu'un mécanisme de cliquet 20 associé à La roue supérieure 16 permet d'éviter toute descente accidentelle du bati 8 sous l'effet du poids de la charge posée sur le plateau 11, tout en autorisant, moyennant intervention manuelle, le déplacement vers le bas dudit bâti sous l'effet de la manivelle 15, lorsque désiré. The vertical displacement of the frame 8 and of the plate 11 that it supports tilting is effected by means of an upper crank 15 (fig. 1) wedged on a small shaft on which is fixed a toothed wheel 16 connected by a chain vertical 17 to a lower toothed wheel 18 carried by the rear cross member of the chassis 1. The ends of this chain 17 are joined to each other by a fastener 19 made integral with the lower bar of the frame 8. It will be observed that a ratchet mechanism 20 associated with the upper wheel 16 makes it possible to avoid any accidental descent of the frame 8 under the effect of the weight of the load placed on the plate 11, while allowing, by manual intervention, the downward movement of said built under the effect of the crank 15, when desired.

Le fonctionnement et Le mode d'utilisation du chariot ci-dessus décrit découlent des explications qui précèdent et se comprennent aisément. The operation and mode of use of the above-described carriage follow from the foregoing explanations and are easily understood.

Le bati 8 étant supposé à la position basse pour laquelLe son plateau 11, immobilisé angulairement par le verrou 13, est situé immediatement au-dessus du châssis 1, l'utilisateur peut déposer sur ledit plateau la charge à manutentionner. Le chariot peut alors être amené jusqu'au point de déchargement. L'actionnement de la manivelle 15 assure
L'élévation de la charge jusqu'à la hauteur désirée. IL suffit de manoeuvrer le verrou 13 au retrait pour libérer le plateau 11 qui bascule sous l'effet du poids en porte-å-faux de La charge. Celle-ci est ainsi susceptible d'être déchargée dans le coffre d'une voiture ou en tout autre emolacement désisté. The frame 8 being assumed to be in the low position for which the tray 11, angularly immobilized by the bolt 13, is located immediately above the chassis 1, the user can deposit the load to be handled on said tray. The trolley can then be brought to the point of unloading. The actuation of the crank 15 ensures
The lifting of the load to the desired height. It suffices to maneuver the latch 13 when withdrawing to release the plate 11 which swings under the effect of the cantilever weight of the load. It is thus likely to be unloaded in the trunk of a car or in any other emolement discontinued.

On conçoit que le basculement du plateau 11 a provoqué l'extension des deux éléments du vérin 12 et la compression du gaz renfermé par ce dernier, en opérant de La sorte Le freinage du mouvement de basculement. It will be understood that the tilting of the plate 11 has caused the extension of the two elements of the jack 12 and the compression of the gas enclosed by the latter, thereby operating The braking of the tilting movement.

Dès que La charge a été déversée, Le vérin ramène élastiquement le plateau 11 à la position normale et en fin de course de retour le verrou 13 s'encliquéte automatiquement en position bloquée, sans aucune intervention manuelle.As soon as the load has been discharged, the jack resiliently returns the plate 11 to the normal position and at the end of the return stroke the latch 13 automatically engages in the locked position, without any manual intervention.

IL va de soi que le vérin à gaz 12 est susceptible d'être remplacé par tout autre systéme de compression élastique. En certains cas, il peut être avantageux de substituer à La manivelle 15 un petit moteur électrique associé à l'une ou L'autre des deux roues dentees 16 et 18 et alimenté par une batterie d'accumulateurs, supportée par exemple par les goussets 4 destinés au montage des roues orientables 3. It goes without saying that the gas spring 12 is capable of being replaced by any other elastic compression system. In some cases, it may be advantageous to replace the crank 15 with a small electric motor associated with one or the other of the two toothed wheels 16 and 18 and powered by a storage battery, supported for example by the gussets 4 for mounting steerable wheels 3.

IL doit d'ailleurs etre entendu que La description qui précède n'a été donnée qu'à titre d'exemple et qu'elle ne Limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents.  It should moreover be understood that the above description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents.
