Abstract

L'invention concerne un cardan portatif à deux axes (100) comprenant une poignée (10), un premier moteur (20), un support de liaison (30), un second moteur (40), une structure de support (50) et une structure de liaison (60). Le premier moteur (20) présente une surface supérieure (21) et une surface inférieure disposées à l'opposé l'une de l'autre, et une paroi latérale (22) située entre la surface supérieure (21) et la surface inférieure. La surface inférieure est reliée à la poignée (10). Le premier moteur (20) est utilisé pour entraîner une charge (200) en rotation autour d'un premier arbre de moteur. Une extrémité du support de liaison (30) est reliée au premier moteur (20). L'autre extrémité du second moteur (40) est reliée à l'autre extrémité du support de liaison (30) pour entraîner la charge (200) en rotation le long d'un second arbre de moteur. La structure de support (50) est reliée au second moteur (40) pour supporter la charge (200). La structure de liaison (60) est disposée sur la surface supérieure (21) du premier moteur (20). Le support de liaison (30) peut être relié de manière rotative au premier moteur (20) au moyen de la structure de liaison (60) et peut être tourné dans une direction perpendiculaire au premier arbre de moteur de telle sorte que le cardan portatif à deux axes (100) soit commuté entre un état d'utilisation et un état de pliage. Le cardan portatif à deux axes (100) occupe un petit espace après avoir été plié et est pratique à transporter et à stocker.
