Abstract

La présente invention concerne un système d'arbre portatif avec des moyens pour attacher et faire fonctionner divers types d'équipement. Le système d'arbre portatif (100 ; 200 ; 300 ; 400), comprend une tige (110 ; 210 ; 310 ; 410) ayant une première extrémité longitudinale et une seconde extrémité longitudinale ; un premier raccord (120a ; 220a ; 320a ; 420a) et un second raccord (120b ; 220b ; 320b ; 420b), chaque raccord étant relié à une extrémité longitudinale respective de la tige et accouplé de façon mobile entre eux ; une unité de couplage (140 ; 240 ; 340 ; 440) reliée au second raccord (120b ; 220b ; 320b ; 420b) ; une poignée (130 ; 230 ; 330 ; 430) reliée au premier raccord (120a ; 220a ; 320a ; 420a), de sorte qu'un mouvement de la poignée (130 ; 230 ; 330 ; 430) par rapport au premier raccord (120a ; 220a ; 320a ; 420a) actionne un mouvement de l'unité de couplage (140 ; 240 ; 340 ; 440) par rapport au second raccord (120b ; 220b ; 320b ; 420b) ; un outil ou un équipement (150 ; 250 ; 350 ; 450), et l'unité de couplage (140 ; 240 ; 340 ; 440) comprenant des moyens de couplage conçus pour permettre à l'unité de couplage (140 ; 240 ; 340 ; 440) de se coupler de manière détachable audit outil ou audit équipement (150 ; 250 ; 350 ; 450).
