Abstract

The present invention concerns a mechanism (1), comprising: one support (2) including a base (3), one pendulum (4), and connecting suspension rods (5) articulated on the base (3) and on the pendulum (4); two mobile cog wheels (12; 22) in rotation around their respective axis (A1; A2); two eccentric elements (14; 24) integral with the cog wheels (12; 22) in rotation and generating moments of gravity force around their axis (A1; A2); and one connecting link rod (60; 160) comprising a rotary head (62) and an eccentric head (63). The axis (A1; A2) are parallel within a horizontal or vertical reference plane (P0). The pendulum (4) supports the axis (A1; A2) of the cog wheels (12; 22) and of the eccentric elements (14; 24). The connecting rods (5) are slanting in accordance with an angle comprised between 45 degrees and 80 degrees in relation to a vertical plane. The cog wheels (12; 22) engage one with the other using a unitary transmission ratio and are mobile in rotation in opposing directions. When the mechanism (1) is in operation, the eccentric elements (14; 24) follow an elliptical movement, whereas the pendulum (4) follows a travel movement having a vertical component and a horizontal component. The moments of gravity force of the eccentric elements (14; 24) have a same value and a same direction, both being variable depending on their angular position around the axis (A1; A2). For each angular position of the cog wheels (12; 22) and of the eccentric elements (14; 24) around the axis (A1; A2), the mechanism (1) presents an equilibrium configuration at rest.
