Device for stabilizing vehicles during extended parking, particularly for large vehicles

摘要

A device for stabilizing vehicles during extended parking, particularly for large vehicles such as campers, caravans, trucks, farming machines and vehicles, earth-moving machines, and the like, the device comprising a lifting jack (11), which is rotationally pivoted, by opposite ends, respectively to the chassis (12) of the vehicle to which it is applied and to a foot (13) for contact against a stabilization surface. The jack (11) comprises two identical and mutually opposite pairs of arms (16) that are mutually articulated by means of rotational hinges so as to form functionally an articulated quadrilateral (17). The articulated quadrilateral (17) comprises two first mutually opposite hinges (18), termed intermediate hinges, which are connected, by means of a translational actuator automated by means of a gearmotor (19), and two second hinges (20), which are respectively associated with the chassis (12) and with the contact foot (13). The device allows the vehicle to move, if it sets off accidentally without lifting the jack (11) from the contact surface; the jack (11) in fact rotates about its own hinge for coupling to the chassis (12), disengaging from the ground.
