1. An apparatus for muscle and joint exercise, adapted to reeducation and/or physical conditioning of a body part of a user, said apparatus comprising:
a hollow body, open at one of the ends thereof and having a bottom at the end opposite the open end, said body being elongated along a main axis and said bottom of the body being removably mounted on a base slidingly mounted in a frame; a mobile member comprising an elongated arm slidingly mounted inside the body and translatable inside the body along said main axis and said arm going through the open end of said body, said arm being movable between a retracted position and a deployed position and being designed to be displaced by the body part of the user and also for displacing said body part; a motor-driven system comprising a motor arranged inside a case fastened to said bottom of the body, said motor being connected to the arm and adapted for driving in displacement the arm in both translatory directions, and also for decelerating displacement of the mobile member in both translatory directions; wherein the mobile member is not a telescopic arm and the arm has two opposite ends, a first free end on which a connecting member is arranged so that the user can both pull and push the arm and so that the user can both be pulled and pushed by the arm, and a second end connected to the motor, and wherein the body has a length comprised between 700 and 1500 mm and the arm has a maximum translatory stroke comprised between 500 and 1000 mm; a plurality of guiding elements arranged inside the body and fastened to said body, said guiding elements being configured for guiding said arm in the translator movement thereof and for sustaining the radial efforts perpendicular to the main axis;
wherein the guiding elements provide a substantially isostatic guiding of the arm by comprising several tie bars extending inside the body in parallel to the main axis, and at least one slide slidingly mounted on each of said tie bars and fixedly mounted on the arm, said tie bars respectively comprising a back end fastened to the case of the motor;at least one hinge configured for articulating the body on the frame, said hinge being arranged on the bottom of the body and providing at least one degree of rotational freedom for the body around an axis of rotation. |
