Abstract
Description
La présente invention concerne un mécanisme de repliage automatique de roues destiné à équiper un chariot conçu pour le transport de marchandises, permettant d'introduire ce chariot directement avec sa marchandise dans un véhicule automobile sans recourir à son déchargement avant la phase d'introduction. The present invention relates to an automatic wheel folding mechanism intended to equip a trolley designed for the transport of goods, making it possible to introduce this trolley directly with its goods into a motor vehicle without having to unload it before the introduction phase.
L'invention est caractérisée par la conception du mécanisme de repliage des roues suivant des bras articulés en forme de parallélogramme. The invention is characterized by the design of the wheel folding mechanism according to articulated arms in the shape of a parallelogram.
Au préalable avant l'introduction du chariot (1) dans le véhicule automobile, il est nécessaire de dévérouiller manuellement les mécanismes en tirant sur le levier (2) afin de libérer la fonction repliage des roues. Before the introduction of the carriage (1) into the motor vehicle, it is necessary to manually unlock the mechanisms by pulling on the lever (2) in order to release the folding function of the wheels.
Les systèmes de dévérouillage et de vérouillage des mécanismes étant de conception courante, ils ne feront l'objet d'aucune originalité, ils ne sont pas traités ni décrits et ne font l'objet d'aucune revendication. The mechanisms for unlocking and locking the mechanisms being of current design, they will not be the subject of any originality, they will not be treated or described and will not be the subject of any claim.
L'utilisateur pousse le chariot (1) à l'aide de la poignée vers l'intérieur du véhicule, le galet (3) prend contact avec le véhicule mais ne commande pas directement la levée de la roue (8) ,celle ci se faisant grâce à la combinaison des bras articulés (5) (6) et (7) reliés entre eux par des axes formant un ensemble de bras du type à parallélogramme ceci dans le but exclusif d'offrir une cinématique appropriée. The user pushes the carriage (1) using the handle towards the interior of the vehicle, the roller (3) makes contact with the vehicle but does not directly control the lifting of the wheel (8), it by virtue of the combination of the articulated arms (5) (6) and (7) interconnected by axes forming a set of arms of the parallelogram type, this with the sole aim of providing suitable kinematics.
La figure 1 représente le chariot en butée contre le seuil du véhicule (4), la figure 2 montre le début de la mise en action des bras articulés assurant la levée des roues avant (8), la figure 3 illustre une autre étape de l'introduction du chariot dans le véhicule. FIG. 1 represents the carriage in abutment against the threshold of the vehicle (4), FIG. 2 shows the start of actuation of the articulated arms ensuring the lifting of the front wheels (8), FIG. 3 illustrates another step of the introduction of the carriage into the vehicle.
La même combinaison de bras articulés à parallélogramme est utilisée pour le repliage des roues arrières (10), le galet (11) en contact avec le véhicule commande la levée des bras articulés (12) (13) et (14), la figure 4 en est l'illustration. The same combination of articulated arms with parallelogram is used for folding the rear wheels (10), the roller (11) in contact with the vehicle controls the lifting of the articulated arms (12) (13) and (14), Figure 4 illustrates this.
Les bras du type à parallélogramme présentent l'avantage d'offrir le repliage des roues de façon automatique sans manipulation autre que de pousser manuellement sur la poignée du chariot après dévérouillage du système suivant le levier (2). The arms of the parallelogram type have the advantage of folding the wheels automatically without any manipulation other than pushing manually on the handle of the trolley after unlocking the system according to the lever (2).
L'emploi de bras du type à parallélogramme permet d'obtenir non seulement la cinématique appropriée de repliage des roues mais offre l'avantage de ranger les roues dans la même surface occupée du chariot en vue de face, la figure 5 en est l'illustration, toutes les roues sont contenues à l'intérieur du périmètre constitué par le chariot, aucune partie du mécanisme ne sort de ce périmètre. The use of arms of the parallelogram type makes it possible not only to obtain the appropriate kinematics for folding the wheels but offers the advantage of storing the wheels in the same occupied surface of the carriage in front view, FIG. 5 is the illustration, all the wheels are contained within the perimeter formed by the carriage, no part of the mechanism leaves this perimeter.
Il est à noter que la géométrie et la longueur des bras est différente suivant s'il s'agit des roues avant (8) ou des roues arrières (10) car elles sont en rapport avec la dimension des roues et leur position de repliage, et sont conçues de façon à accepter le montage de roues de grand diamètre à l'avant du chariot dans le but de garantir une bonne stabilité au roulage. It should be noted that the geometry and the length of the arms is different depending on whether it is the front wheels (8) or the rear wheels (10) because they are related to the size of the wheels and their folding position, and are designed to accept the mounting of large diameter wheels at the front of the truck in order to guarantee good rolling stability.
En position replié le chariot peut rouler à l'intérieur du véhicule par l'intermédiaire des roues (9) (8) et (10). In the folded position the trolley can roll inside the vehicle by means of the wheels (9) (8) and (10).
L'opération de déchargement du chariot du véhicule vers le sol s'effectue de la même manière à l'inverse de l'opération d'introduction, il suffit de tirer sur la poignée du chariot et vers l'arrière du véhicule. The operation of unloading the truck from the vehicle to the ground is carried out in the same way, unlike the insertion operation, it suffices to pull the handle of the truck and towards the rear of the vehicle.
Ce mécanisme à bras du type à parallélogramme offre la particularité de se replier sous un volume le plus réduit et compact possible, il présente l'avantage de ne pas pénaliser son rangement à l'interieur de la plus grande variété d'automobiles possible. This arm mechanism of the parallelogram type offers the particularity of folding up to the smallest and most compact volume possible, it has the advantage of not penalizing its storage inside the largest variety of cars possible.
