Abstract
Description
La présente invention concerne un chariot de manutention à roulettes,The present invention relates to a trolley with wheels,
lesté de sa charge, facilement embarqué ou débarqué de tout véhicule par son seul utilisateur. weighted with its load, easily shipped or unloaded from any vehicle by its sole user.
Le débarquement des charges et de leur chariot de manutention étant jusqu' alors fastidieuse du fait du poids et de l'encombrement de ces différents éléments;On avait donc l'habitude,soit de faire appel à une aide extérieùre;engin élévateur ou tierce personne; Soit de débarquer successivement le chariots puis ses différentes charges. Le cas extrême ou il y a absence de chariot obligeant l'utilisateur à porter lui-même les charges depuis son véhicule jusqu'à tout autre endroit. The unloading of the loads and of their handling trolley being until then tedious because of the weight and bulk of these various elements, it was therefore customary either to call upon an outside help, elevator or third person ; Either to disembark the carts successively then its different loads. The extreme case where there is no truck requiring the user to carry himself the loads from his vehicle to any other place.
Ce chariot selon l'invention permet de remédier à ces inconvénients. Une action 10 volontaire de l'utilisateur sur le mécanisme équipant son chariot, aura pour effet de définir trois états particuliers de celui-ci. Principe: FIGURE 4 Le premier état est le - mode utilisation FIGURE 1 En cet état le chariot comporte sa poignée de poussée/traction (1) équipée de deux bras de levier;Un à gauche (2s) et un à droite (2) . Deux plateaux de rangement superposés et de dimensions appropriées sont alors facile d'accès car leur distance relative tant verticale qu'horizontale permet la préhension de tout objet s'y trouvant. This carriage according to the invention overcomes these disadvantages. A voluntary action by the user on the mechanism equipping his carriage will have the effect of defining three particular states thereof. Principle: FIGURE 4 The first state is - use mode FIGURE 1 In this state the carriage has its push / pull handle (1) equipped with two lever arms, one on the left (2s) and one on the right (2). Two superimposed storage trays and appropriate dimensions are then easy to access because their relative distance both vertical and horizontal allows the gripping of any object therein.
Ces deux plateaux sont reliés entre eux par les axes de rotation de deux bielles à gauche et deux bielles à droite.Dans chacune des paires de bielles,une est formée par un des deux bras de levier de la poignée (2 et2s) .Les quatre axes respectifs des deux paires de bielles forment un parallélogramme L' ensemble plateau,bielles, poignée, est articulé par deux axes à gauche(B 1 s et B2s) et deux à droite (B1 et B2) autour de deux potences;une gauche (10s) et une droite(10) .Ces axes forment aussi un parallélogramme avec les axes (Al et A2) du plateau supérieur (4) .11 en est de même avec les axes du plateau inférieur (5) . Les deux potences (10 etl0s)sont réglées par coulissement puis verrouillage par vis dans le porte roulettes (7) , de sorte que la distance (Ll) sol / dessous du plateau(5) soit supérieure de quelques millimètres à la distance du sol au dessus du plancher du véhicule.Les roulettes (8) et (8s) pourront être fixes.Les roulettes (9) et(9s) pourront être folles. These two plates are interconnected by the axes of rotation of two rods on the left and two rods on the right. In each of the pairs of rods, one is formed by one of the two lever arms of the handle (2 and 2s). respective axes of the two pairs of rods form a parallelogram The whole plate, rods, handle, is articulated by two axes on the left (B 1 s and B2s) and two on the right (B1 and B2) around two brackets, a left ( 10s) and a straight line (10). These axes also form a parallelogram with the axes (A1 and A2) of the upper plate (4). It is the same with the axes of the lower plate (5). The two brackets (10 etl0s) are slidably adjusted and screw locked in the roller carrier (7), so that the distance (L1) from the ground to the bottom of the plate (5) is several millimeters greater than the distance from the ground to the ground. The wheels (8) and (8s) can be fixed. The wheels (9) and (9s) can be crazy.
L'aplomb du centre de gravité des deux plateaux chargés sera situé de telle façon qu'il engendrera une force de rotation liée au poids tendant à faire diminuer l'angle alpha vers zéro. Cependant une butée antagoniste sera présente entre les deux bielles (2) et (3)et leurs symétrique afin d'annuler cette chute. The center of gravity of the two loaded trays will be located in such a way that it will generate a rotation force related to the weight tending to decrease the angle alpha towards zero. However, an opposing abutment will be present between the two connecting rods (2) and (3) and their symmetrical in order to cancel this fall.
Le deuxième état est le mode embarquement FIGURE 2 En cet état l'utilisateur étant désireux d'embarquer son chariot avec sa charge devra, après avoir poussé celui-ci contre son véhicule (plateaux en avant) et ainsi amené en butée les potences (10 et 10s) ; Doit exercer une force vers le haut sur la poignée (1) , tendant à faire tourner les bras (2 et 2s) de la position horizontale vers la verticale;modifiant ainsi l'angle alpha 1 (Fig. l) vers l'angle alpha 2 (Fig.2).Ce mouvement rotatif a pour effet d'entraîner tous les éléments liés entre eux par les différents axes (cités auparavant) formant parallélogramme. C'est-à-dire les bras (2 et 3) , (2s et 3s), ainsi que les plateaux (4 et 5). La fin de ce mouvement est définie par le moment ou les bras (2 et 2s) viennent buter sur les bielles (3 et 3 s) . par cette action, la cote Ll (sol /dessous du plateau (5)) devient L2 (sol /dessous du plateau 5) ; cette nouvelle cote L2 est, d'après l'étude et les dimensions données à chaque élément, inférieure à la cote entre le dessus du plancher véhicule et le sol.Le résultat physique est que le plateau(5) se retrouve posé sur le plancher véhicule, et que les quatre roulettes du chariot sont décollées du sol de quelques millimètres.En cet état,la poignée,les bras,les bielles, les plateaux, et leur contenu sont posés dans le véhicule. The second state is the boarding mode FIGURE 2 In this state the user being eager to board his truck with his load must, after pushing it against his vehicle (trays forward) and thus brought to a stop the gallows (10 and 10s); Must exert an upward force on the handle (1), tending to rotate the arms (2 and 2s) from the horizontal position to the vertical, thus changing the angle alpha 1 (Fig. 1) to the angle alpha 2 (Fig.2) .This rotary movement has the effect of driving all the elements linked together by the different axes (previously mentioned) forming parallelogram. That is to say the arms (2 and 3), (2s and 3s), as well as the trays (4 and 5). The end of this movement is defined by the moment when the arms (2 and 2s) abut on the connecting rods (3 and 3 s). by this action, the dimension L1 (ground / bottom of the plateau (5)) becomes L2 (ground / bottom of the plateau 5); this new L2 rating is, according to the study and the dimensions given to each element, lower than the dimension between the top of the vehicle floor and the ground. The physical result is that the plate (5) is placed on the floor vehicle, and that the four wheels of the carriage are off the ground a few millimeters.In this state, the handle, arms, rods, trays, and their contents are placed in the vehicle.
Le troisième état est le mode Transport FIGURE 3 Afin d'envisager le transport du chariot; Il faut que la structure (7) ,ses roulettes, et les potences (10 et 10s) soient aussi à l'intérieur du véhicule. Cet ensemble étant lié mécaniquement,et à ce moment de façon rigide,aux plateaux,bras et bielles par le biais des deux axes Bl etB2; Il faut désaccoupler les bras (2 et 2s) ,des potences (10 et 10s) ,en retirant l'axe B1.pour ce faire on pourra utiliser un axe à dévisser actionné par un bouton cranté (rep.6 et son symétrique) ou tout autre moyen plus ou moins sophistiqué 25.L'ossature (7) et ses potences étant, selon l'étude décollées du sol d'une valeur suffisante; l'utilisateur peut alors les faire tourner de cent quatre vingt degrés autour de l'axe B2; vers l'intérieur du véhicule. La fin de cette rotation étant définie par une butée mécanique. Le chariot est alors chargé dans le véhicule. The third state is the transport mode FIGURE 3 In order to envisage the carriage transport; It is necessary that the structure (7), its wheels, and the brackets (10 and 10s) are also inside the vehicle. This assembly being mechanically linked, and at this moment rigidly, to the plates, arms and connecting rods via the two axes Bl and B2; The arms (2 and 2s), the brackets (10 and 10s) must be disconnected by removing the B1 axis. To do this we can use a pin to be unscrewed actuated by a notched knob (rep.6 and its symmetrical) or any other means more or less sophisticated 25.The structure (7) and its gallows being, according to the study taken off the ground of sufficient value; the user can then rotate them by one hundred and eighty degrees around the B2 axis; towards the inside of the vehicle. The end of this rotation being defined by a mechanical stop. The truck is then loaded into the vehicle.
Le débarquement et la mise en service du chariot suivent le même 30 processus, en appliquant rigoureusement la chronologie inverse. The disembarkation and commissioning of the trolley follow the same process, rigorously applying the reverse chronology.
Différentes options sont prévus à partir de ce modèle de base. En voici quelques exemples: -Possibilité d'équiper le plateau (5) de roulettes pour le déplacer dans le véhicule -Remplacer le plateau (4) par deux bielles permettant de transporter de grosses charges uniquement sur le plateau (5). Different options are provided from this basic model. Here are some examples: -Possibility to equip the platform (5) with wheels to move it in the vehicle -Replace the plate (4) by two connecting rods to transport large loads only on the plate (5).
-Installer des vérins ou des ressorts de compression dans le cas de lourdes charges afin de diminuer la force résultante sur la poignée lors de l'embarquement / débarquement. -Install cylinders or compression springs in the case of heavy loads in order to decrease the resulting force on the handle during the embarkation / disembarkation.
