<p>The invention refers to a mechanism that maintains the horizontal position of a carrier independently of the inclination of its base. The mechanism is consisted of the carrier system (1, 2, 3), the cavity system (4, 5) which is lean on a stationary base (10, 11) and the equalizer system (7, 8, 9). The plane surface (1) sits on the carrier (2) and it is connected to the equalizer through the rod (8). The carrier can slide on the outside semi-spherical surface of the cavity (4). The sphere (7) of the equalizer can slide on the inner semi-spherical surface of the cavity and the equalizer through its counterweight (9) tends to keep its vertical position. Therefore, the plane surface (1), which is at 90° with respect to the rod (8), tends to maintain its horizontal position.</p> |
