Abstract

The invention relates to a device allowing the end part of a tailgate platform made from two parts which can be folded onto one another to be folded automatically. It consists of a drum 1 wedged on the rotation shaft 2 of the foldable part 3 and secured to the latter. This drum is rotationally driven by a chain 4 fixed on one side to its periphery and on the other side to the periphery of a drum 5 fixed securely to the platform 7 support 6 and situated close to the rotation shaft 8 of this platform. A spring 9 deploys the foldable part 3 of the platform on opening.

Description

La présente invention concerne la fermeture automatique de la partie repliable d'une plateforme en deux parties. The present invention relates to the automatic closing of the foldable part of a platform in two parts.

Afin d'éviter de boucher la visibilité de la lunette arrière d'un véhicule, la plateforme du hayon est exécutée en deux parties repliables l'une sur l'autres
La première opération consiste å replier manuellement la partie extreAme de la plateforme sur la partie la plus proche du véhicule.In order to avoid obstructing the visibility of the rear window of a vehicle, the tailgate platform is made in two foldable parts, one on top of the other.
The first operation consists in manually folding the outer part of the platform onto the part closest to the vehicle.

La deuxième opération qui est la fermeture de l'ensemble des deux parties replies l'une sur l'autre s'effectue automatiquement. The second operation, which is the closure of all of the two parts folded over one another, is carried out automatically.

La première opération manuelle ne peut être effectuée par un handicapé en fauteuil roulant. The first manual operation cannot be carried out by a disabled person in a wheelchair.

Le dispositif objet de l'invention permet de remédier à cet in convéni ent.  The device which is the subject of the invention makes it possible to remedy this inconvenience.

Il comporte un tambour calé sur l'axe de rotation de la partie repliable de la plateforme et solidaire de celle-ci, ce tambour est entraîné en rotation par une chaîne fixée à sa périphérie qui s'enroule, lors de la fermeture de la plateforme, autour d'un autre tambour fixe solidaire du support de la plateforme et situé sur ou près de son axe d' articulation. It comprises a drum fixed on the axis of rotation of the foldable part of the platform and integral with the latter, this drum is driven in rotation by a chain fixed at its periphery which is wound, when the platform is closed , around another fixed drum secured to the support of the platform and located on or near its axis of articulation.

La liaison entre ces deux tambours est telle que leur mouvement relatif est de sens inverse. The connection between these two drums is such that their relative movement is in the opposite direction.

Le tambour fixé près de l'axe de rotation de la plateforme ayant un diamètre égal au double de celui du tambour d'entraînement de la partie repliable, cette dernière effectuera un demi tour et viendra plaquer sur la plateforme qui aura effectué un quart de tour. The drum fixed near the axis of rotation of the platform having a diameter equal to twice that of the drive drum of the folding part, the latter will make a half turn and will come to press on the platform which will have made a quarter turn .

Les rapports de diamètre seront légèrement différents suivants la position du tambour fixe solidaire du support de plateforme. The diameter ratios will be slightly different depending on the position of the fixed drum secured to the platform support.

Un ressort assure le déploiement de la partie repliable lors de l'ouverture.  A spring ensures the deployment of the folding part during opening.

En variante les deux tambours peuvent être remplacés soit par deux pignons, dans ce cas la commande est faite par une chaîne croisée, soit par un train d'engrenages, dans ce cas le ressort de déploiement est inutile. As a variant, the two drums can be replaced either by two pinions, in this case the control is made by a crossed chain, or by a gear train, in this case the deployment spring is useless.

La figure 1 représente un dispositif suivant l'invention. Figure 1 shows a device according to the invention.

Le dispositif représenté sur la figure 1 comporte un tambour (1) calé sur l'axe de rotation (2) de la partie repliable (3) et solidaire de celle-ci. The device shown in Figure 1 comprises a drum (1) wedged on the axis of rotation (2) of the foldable part (3) and secured thereto.

Un tambour (1) est entraîné par une chaîne (4) fixée d'un côté à la périphérie dudit tambour (1) et de l'autre à la périphérie d'un autre tambour (5) dont le diamètre est sensiblement double de celui du tambour (1). Le tambour (5) est fixé et solidaire du support (6) de plateforme et situé près de l'axe de rotation de cette dernière. A drum (1) is driven by a chain (4) fixed on one side to the periphery of said drum (1) and on the other to the periphery of another drum (5) whose diameter is substantially double that of of the drum (1). The drum (5) is fixed and integral with the platform support (6) and located near the axis of rotation of the latter.

Lors de la fermeture automatique de la plateforme (7), la chaîne (4) s'enroule autour du tambour (3) ce qui raccourcit et entrasse en rotation le tambour (7) ainsi que la partie repliable (3) de la plateforme. During the automatic closing of the platform (7), the chain (4) winds around the drum (3) which shortens and rotates the drum (7) as well as the foldable part (3) of the platform.

Le tambour (5) ayant un diamètre double de celui du deuxième tambour (1) après un quart de tour de l'ensemble de la plateforme la partie repliable (3) aura a exécuter un demi tour et sera repliée sur la plateforme (7). The drum (5) having a diameter twice that of the second drum (1) after a quarter turn of the entire platform the folding part (3) will have to perform a half turn and will be folded back on the platform (7) .

Un ressort (9) assure le déploiement de la partie repliable (3) de la plateforme lors de l'ouverture. A spring (9) deploys the foldable part (3) of the platform during opening.

Dans une variante les deux tambours (1) et (5) peuvent être remplacés par deux pignons reliés par une channe croisée ou deux poulies crantées reliées par une courroie croisée ou par un jeu de pignon tels que celui relié à la partie repliable tourne deux fois plus vite que celui solidaire de l'axe fixe et en sens inverse.  In a variant the two drums (1) and (5) can be replaced by two pinions connected by a crossed chain or two notched pulleys connected by a crossed belt or by a set of pinions such as that connected to the folding part rotates twice faster than that secured to the fixed axis and in the opposite direction.
