<p>The rack comprises a flat fixed frame (2) associable to a bearing structure and having a front portion (2a) and a rear portion (2b); a flat mobile frame (3), slidable and rotatable with respect to the fixed frame (2); a main arm (4), which has a first end (4a) which is rotatingly constrained to the fixed frame (2) about a main rotation axis (y), and a second end (4b), slidably constrained to the mobile frame (3) in a sliding direction (x) and a rotating direction about a parallel axis to the main rotation axis (y); means for compensating operatively interpositioned between the fixed frame (2) and the main arm (4) and predisposed to act in opposition, with a predetermined force, to rotation of the main arm (4).</p> |
