Abstract

The device has a set of tread rollers (3) around which a serrated or smooth belt (5) is rolled. A spring device i.e. tensioner, automatically stretches the belt. A motor reducer/ torque limiter (13) is inserted into a suitcase to transmit power to the belt through a drive cogwheel (9) and a drive shaft (7) and to a serrated roller-motor (8), where the torque limiter and the serrated roller-motor are isolated in a protection box (12). The motor is supplied with power from a rechargeable battery or a solar panel.

Description

DESCRIPTION Cf. Figures 1 à 5 en annexe. La présente invention concerne un dispositif (système mécanique) permettant de déplacer sans effort une valise (ou autre objet à fond plat) sur des marches d'escalier ou sur un plan incliné : montée ou descente. Les valises lourdes sont en effet traditionnellement portées et soulevées à 5 bout de bras dans les escaliers des aéroports ce qui est d'une grande incommodité. Ce dispositif novateur permet de remédier à cet inconvénient. En effet, l'utilisateur se contente de tenir la poignée de la valise (de masse l'ordre de 30 kg) et accompagne simplement son ascension ou sa descente le long des escaliers (dont la pente est d'environ 301.DESCRIPTION See Figures 1 to 5 in the appendix. The present invention relates to a device (mechanical system) for effortlessly moving a suitcase (or other flat-bottomed object) on steps or on an inclined plane: ascent or descent. Heavy suitcases are indeed traditionally worn and lifted at arm's length on the stairs of airports which is a great inconvenience. This innovative device overcomes this disadvantage. Indeed, the user is content to hold the handle of the bag (mass about 30 kg) and simply accompanies his ascent or descent along the stairs (whose slope is about 301.

10 Ainsi, l'ensemble comprend une valise dans laquelle, à sa base inférieure centrale, un coffret de protection {12} contient le système motoréducteur/limiteur de couple {13} qui transmet sa puissance au système galets {3} - courroies, suivant l'adhérence, crantées ou lisses {5} par l'intermédiaire des 2 galets - moteurs crantés {8}. En effet, le système motoréducteur délègue sa puissance à la roue dentée 15 d'entraînement {9} ainsi qu'à l'axe d'entraînement en acier {7}, aux galets-moteurs crantés {8} et, de ce fait, aux 2 courroies crantées ou lisses {5}. La présence d'un tendeur de courroie est indispensable pour le bon fonctionnement du système. Un moteur électrique de faible puissance de l'ordre de 120 à 200 watts alimenté par une batterie ou panneau solaire adapté, avec un réducteur, un limiteur 20 de couple, un système électronique à télécommande, fera monter (force motrice) ou descendre (frein-moteur) cette valise. Celle-ci, une fois posée sur un escalier, le limiteur de couple régularise la vitesse de son déplacement au gré du voyageur. En définitive, l'invention a été initialement conceptualisée pour une valise mais elle peut également s'appliquer à tout autre système dont l'utilité est similaire.Thus, the assembly comprises a case in which, at its central lower base, a protective box {12} contains the geared motor / torque limiter {13} which transmits its power to the system of rollers {3} - belts, following adhesion, notched or smooth {5} by means of the 2 rollers - toothed motors {8}. Indeed, the geared motor system delegates its power to the drive gear {9} as well as to the steel drive shaft {7}, toothed motor rollers {8} and, therefore, 2 toothed or smooth belts {5}. The presence of a belt tensioner is essential for the proper functioning of the system. A low power electric motor of the order of 120 to 200 watts powered by a battery or solar panel adapted, with a reducer, a torque limiter 20, a remote control electronic system, will raise (driving force) or go down (brake -motor) this suitcase. This one, when put on a staircase, the limiter of torque regulates the speed of its displacement at the option of the traveler. In the end, the invention was initially conceptualized for a suitcase but it can also be applied to any other system whose utility is similar.

La figure 5 fournit la nomenclature de ces éléments.The accompanying drawings illustrate the invention: FIGS. 1 and 2 provide a general view of the operation. Figures 3 and 4 show in detail the elements constituting the invention. Figure 5 provides the nomenclature of these elements.
