Description

Dispositif amortisseur des éléments mobil d'un châssis à géométrie variable par triangulation, destiné à équiper tous chariots munis d'au moins un essieu, à fin de sécuriser le transport d'êtres vivants ou de marchandises. La présente invention entre dans le domaine particulier d'éléments mobil, mécaniques ou hydrauliques composant une partie du châssis à géométrie variable d'un chariot composé d'une triangulation déformable par coulissement de deux éléments composants cette triangulation, et destiné à amortir les variations de la déformation due à la conformation du terrain lors du transport de marchandises ou de personnes tout en conservant une assiette constante du panier, nacelle ou autre quelque soit la configuration du terrain sur lequel il évolue. Le secteur technique de l'invention est celui de la fabrication d'éléments mécaniques et, ou hydrauliques adaptables aux châssis de chariots munis d'au moins un essieu en vue d'en améliorer les performances et la souplesse de fonctionnement par une action d'amortisseur lors de déplacements sur des terrains accidentés. Lors d'évolutions d'un chariots doté d'un châssis articulé comportant des parties coulissantes, sur 15 des terrains accidentes tels que pentes, escaliers, trottoirs, et autres accidents du terrain, l'utilisateur se trouve confronté à des difficultés dont la brutalité engendrée par la mise en fonction de la variation de la triangulation du châssis induite par l'absence de retenue et de frein au coulissement des parties males et femelles (2,1 et 8) permettant la variation de la géométrie du châssis selon la configuration du terrain et en créant ainsi un danger pour la marchandise ou 20les être transportés. L'objet de la présente invention est de palier à ces dangers et inconvénients par l'adjonction d'amortisseurs intégrés (1) aux parties coulissantes du châssis en vue d'en atténuer la vivacité des mouvements en amortissant et freinant ce mouvement tout en préservant une assiette constante de la charge transportée grâce au système de variation de la géométrie du châssis du 2 S chariot. Ainsi l'inconvénient qui consiste à être confronté à de vives réactions induite au chariot, engendrées du fait que le coulissement des divers éléments composant la partie mobile à géométrie variable du châssis, ne sont pas amortis, donc freinées, lorsque celui-ci est confronté à un obstacle tel que trottoir, escalier mécanique, plans inclinés et autres accidents du terrain et 30 pouvant mettre en danger la cargaison, cet inconvénient disparait grâce à l'action modératrice des amortisseurs. La variation de la géométrie du chariot étant engendrée par la modification de la planimétrie du terrain sur lequel le chariot évolue, il est nécessaire de contenir l'amplitude et la vivacité de cette variation au moyen d'amortisseurs. 35 L'avantage de cette technique permet d'aborder en douceur les obstacles à franchir tout en garantissant une assiette constante au plateau ou autre nacelle de transport dévolue au chariot ainsi que la sauvegarde et préservation du chargement qui ne sera pas soumis à de brusques secousses.Device damping movable elements of a variable triangulation geometry chassis, intended to equip all trolleys equipped with at least one axle, to secure the transport of living beings or goods. The present invention falls within the particular field of mobile, mechanical or hydraulic elements constituting a part of the variable geometry chassis of a carriage composed of a triangulation that can be deformed by sliding of two component elements of this triangulation, and intended to dampen the variations of the deformation due to the conformation of the ground during the transport of goods or persons while maintaining a constant attitude of the basket, nacelle or other whatever the configuration of the terrain on which it evolves. The technical field of the invention is that of the manufacture of mechanical and / or hydraulic elements that can be adapted to the frame of trolleys equipped with at least one axle in order to improve the performance and the flexibility of operation by an action of shock absorber when traveling on rough terrain. When evolutions of a carriages with an articulated chassis having sliding parts, on 15 accident lands such as slopes, stairs, sidewalks, and other accidents of the ground, the user is confronted with difficulties whose brutality generated by the setting in function of the variation of the triangulation of the chassis induced by the absence of restraint and brake sliding of the male and female parts (2,1 and 8) allowing the variation of the geometry of the frame according to the configuration of the and thus creating a danger for the goods or being transported. The object of the present invention is to overcome these dangers and disadvantages by the addition of built-in dampers (1) to the sliding parts of the chassis in order to mitigate the vivacity of the movements by damping and braking this movement while preserving a constant trim of the load transported thanks to the system of variation of the geometry of the chassis of the 2 S trolley. Thus the disadvantage of being confronted with strong reactions induced to the carriage, caused by the fact that the sliding of the various elements making up the mobile part with variable geometry of the frame, are not damped, therefore braked, when it is confronted to an obstacle such as sidewalk, escalator, inclined planes and other accidents on the ground and 30 may endanger the cargo, this drawback disappears thanks to the moderating action of the dampers. The variation of the geometry of the carriage being generated by the modification of the planimetry of the terrain on which the carriage evolves, it is necessary to contain the amplitude and the vivacity of this variation by means of dampers. The advantage of this technique makes it possible to approach the obstacles to be crossed smoothly while guaranteeing a constant attitude to the platform or other transport pod assigned to the carriage as well as the safeguarding and preservation of the load which will not be subjected to sudden jolts. .

Il est connu que l'utilisation d'un chariot à châssis à géométrie variable nécessite de la part de la personne qui le conduit une attention permanente, ainsi si accidentellement l'utilisateur perd le contrôle du chariot, ce dernier, grâce à l'effet des amortisseurs intégrés au châssis gardera sa conformation initiale sans subir de mouvements désordonnés et hors de contrôle, donc la sécurité de la personne ou du lest transporté ne sera pas mise en péril le chariot restant dans la position initiale lors de sa perte de contrôle la souplesse et la résistance aux mouvements désordonnés suffisant à en assurer une assiette constante. Ainsi lorsque le chariot roule sur un sol plat, sans inclinaison ou obstacle l'ensemble triangulation et amortisseur reste passif ( Fig 1). I °Lors de l'accès à un obstacle comme une marche, ( Fig 2)Ia géométrie du châssis change sous l'effet de la poussée induite par les roues (7) sur le tube coulissant (2) articulé sur le châssis (10) en (11) comprimant l'amortisseur (1) lui-même intégré dans le tube support de nacelle (8) la jambe de force (3) repoussant le tube support de la nacelle (8) vers le haut et ainsi permettre le maintient d'une assiette constant à la nacelle ou panier (4).It is known that the use of a chassis trolley with variable geometry requires from the person who conducts permanent attention, so if accidentally the user loses control of the carriage, the latter, thanks to the effect shock absorbers integrated into the chassis will keep its initial conformation without undergoing disordered movements and out of control, so the safety of the person or ballast transported will not be endangered the carriage remaining in the initial position at the time of its loss of control flexibility and the resistance to disordered movements sufficient to ensure a constant trim. Thus when the carriage rolls on a flat ground, without inclination or obstacle the triangulation and damper assembly remains passive (Fig 1). I ° When accessing an obstacle such as a step, (Fig 2) Ia geometry of the chassis changes under the effect of the thrust induced by the wheels (7) on the sliding tube (2) articulated on the chassis (10). ) (11) compressing the damper (1) itself integrated in the nacelle support tube (8) the strut (3) pushing the support tube of the nacelle (8) upwards and thus allow the maintenance a constant attitude to the basket or basket (4).

15 Lors de l'accès à un plan incliné tel un tapis roulant comme il en existe dans les aéroports, grandes surfaces et autre, ou d'un escalier mécanique à la monté comme à la descente, ( Fig 1) les mouvements induits par la configuration du sol compriment ou détendent l'amortisseur ( Fig 2 et 3) freinant ainsi le coulissement de l'ensemble tube (2) amortisseur (1) et tube support de nacelle (8) ce qui évite le risque d'une variation brutale de l'assiette de la nacelle (4) et donc un risque 20 pour la marchandise ou l'être vivant transporté.When accessing an inclined plane such as a treadmill as it exists in airports, supermarkets and other, or a escalator to the mounted as the descent, (Fig 1) the movements induced by the configuration of the ground compresses or relaxes the damper (Fig 2 and 3) thereby slowing the assembly of the tube assembly (2) damper (1) and nacelle support tube (8) which avoids the risk of a sudden change in the plate of the basket (4) and therefore a risk 20 for the goods or the living being transported.
