Abstract

The device has a frame (10) and an operation bar (4) and a set of spreadable slopes i.e. wings (1, 3, 31). A set of wheels (5) is retracted automatically when the operation bar is slackened. A set of loads is arranged such that the set of loads is able to be moved by the wheels. A lever (7) is arranged for opening and closing of the wings. A non-spreadable central slope is limited by the weight of the loads. A base (99) is arranged in a broad manner and is less long when adding weight under the central slope.

Description

Le nouveau dispositif de rampes antidérapantes décrit ci dessous permet de charger ou de décharger un container posé au sol par 1 'ensemble des opérateurs (trices) évitant ainsi le mal de dos. The new anti-slip ramp device described below makes it possible to load or unload a container placed on the ground by all the operators (trices) thus avoiding back pain.

Actuellement, pour charger ou décharger du matériel de 3 tonnes d'un container(exemple : nacelle Haulotte), le personnel utilise de simples plaques en tôle pesant souvent 40 kg ou alors des rampes difficiles à porter seul et qui ne supportent pas les charges lourdes. Currently, to load or unload 3 tons of material from a container (eg Haulotte aerial work platform), the staff uses simple sheet metal plates often weighing 40 kg, or ramps that are difficult to carry alone and do not support heavy loads. .

Description : La rampe est composée de trois parties et à deux fonctions : Les 3 parties sont: - Le châssis (10), - Le système roulant amovible (5, 15) avec sa barre de manoeuvre (4), - Les trois rampes antidérapantes appelées « ailes » (1, 2, 3) dont deux sont déployables (1, 3). La rampe centrale (2) étant déjà inclinée (mais pas obligatoirement) afin d'anticiper la pente. Description: The ramp consists of three parts and two functions: The 3 parts are: - The chassis (10), - The removable rolling system (5, 15) with its maneuvering bar (4), - The three anti-slip ramps called "wings" (1, 2, 3) of which two are deployable (1, 3). The central ramp (2) is already inclined (but not necessarily) to anticipate the slope.

Les 2 fonctions sont: -Le chargement ou le déchargement du matériel -Le déplacement du système. The 2 functions are: -The loading or the unloading of the material -The displacement of the system.

Le déplacement de cette rampe est assuré par des roues ou des roulettes (5) qui s'escamotent automatiquement quand l'opérateur relâche la barre de manoeuvre (4) lorsqu'il charge ou décharge le container. La rampe repose alors sur ses pieds fixes (9), le blocage au sol est ainsi parfaitement assuré. The movement of this ramp is provided by wheels or rollers (5) which retract automatically when the operator releases the maneuvering bar (4) when loading or unloading the container. The ramp then rests on its fixed feet (9), blocking the ground is thus perfectly assured.

Le système est ainsi stable alors que les roues (5) se trouvent sous la rampe (mais inopérantes). Pour déplacer le « chariot rampe » il faut replier les « ailes » (1, 3) (Fig. 2) puis, amener la poignée de la barre de manoeuvre (4) contre le guidon (6) afin que les roues soient opérantes. The system is thus stable while the wheels (5) are under the ramp (but inoperative). To move the "ramp truck" fold the "wings" (1, 3) (Fig. 2) and then move the handle of the control bar (4) against the handlebar (6) so that the wheels are working.

Applications envisagées : Pour toutes les industries, entreprises, commerces, hôtels, etc. ne disposant pas 40 de quai de déchargement ou désirant passer un obstacle (trottoir, marche, bac de rétention, etc.). En version plus légère et moins encombrante, ce système peut être utilisé par les accompagnateurs des personnes à mobilité réduite désirant monter ou descendre 45 une marche, un seuil de porte et ne désirant pas modifier la structure de leurs lieux de vie par des travaux.Applications envisaged: For all industries, businesses, shops, hotels, etc. not having 40 unloading dock or wishing to pass an obstacle (sidewalk, walk, retention tank, etc.). In a lighter and less bulky version, this system can be used by persons accompanying persons with reduced mobility wishing to go up or down a step, a door sill and not wishing to modify the structure of their living areas by work.

50 Optimisations et améliorations possibles : Pour que le système soit plus léger, l'ensemble des éléments (rampes, chariot, renforts, pieds) peut être réalisé en divers matériaux comme l'aluminium ou de la 5 résine ayant forcement une surface antidérapante sur les rampes. Pour que le système soit moins encombrant une fois rangée et repliée (Fig.2), la base (99) peut être beaucoup moins large, en ajoutant à la fabrication des contrepoids quelconques sous la rampe centrale (2) non déployable. (Ceci afin de ne pas renverser 10 le chariot rampes lors de son déplacement). Pour que le système soit plus solide, il est possible de jouer sur le nombre de renforts (8, 10), de pieds fixes (9) ou de pliages (50) ainsi que sur l'épaisseur et sur le choix des matériaux de la rampe. Ceci, en fonction des charges que l'on désire déplacer.50 Optimizations and possible improvements: In order for the system to be lighter, all the elements (ramps, trolley, reinforcements, feet) can be made of various materials such as aluminum or resin having a non-slip surface on them. ramps. For the system to be less bulky once folded and folded (Fig.2), the base (99) can be much narrower, adding to the manufacture of any counterweight under the central ramp (2) not deployable. (This is so as not to tip over the ramp truck when moving it). For the system to be stronger, it is possible to play on the number of reinforcements (8, 10), fixed feet (9) or bends (50) as well as on the thickness and choice of materials of the ramp. This, depending on the loads that you want to move.

15 Ce dispositif peut posséder sur chacune des « ailes » (1, 2, 3, 31) un rebord sur chaque coté, afin de rigidifier l'ensemble et que la charge a déplacer ne dévie pas de sa trajectoire.This device can have on each of the "wings" (1, 2, 3, 31) a flange on each side, to stiffen the assembly and that the load to move does not deviate from its path.

20 Possibilité de changer le pourcentage de la pente. Possibilité d'extension des « ailes » (31) (fig. 1) suivant l'obstacle que l'on désire passer et pour diminuer le pourcentage de la pente.20 Ability to change the percentage of the slope. Possibility of extension of the "wings" (31) (Fig. 1) according to the obstacle that one wishes to pass and to decrease the percentage of the slope.

25 Possibilité de mettre des leviers (7) d'aide à l'ouverture pour les deux rampes déployables (1, 3). Au choix de l'utilisateur, le guidon (6) et les commandes (4, 7) pourront se trouver à droite ou à gauche de ce chariot.Possibility of opening levers (7) for the two deployable ramps (1, 3). At the discretion of the user, the handlebars (6) and the controls (4, 7) may be on the right or left side of this truck.

30 Afin de ne pas abimer le revêtement de sol des patins de protection peuvent être mis en place à la fabrication sur le système. 35 40 45 50 In order not to damage the floor covering, the protective pads can be put in place during manufacture on the system. 35 40 45 50
