Furniture element de mobilier comprenant un plateau articule de surface variable

A furniture element forming a table (1) comprising:

• a base box (2) and several coplanar main plates (3), which are mobile in a circular translation in a common plane,
• a displacement mechanism (4) enabling synchronised displacement of the main plates in the common plane, wherein said plates (3) can assume, because of this mechanism (4), at least two relative configurations, one in which they combine to form a full plate, the other in which the plate they jointly define comprises a central space (51),
• a mobile central plate (5);
• a raising and lowering mechanism (6) which raises or lowers the central plate (5) synchronised relative to displacement of the main plates (3), the circular translation movement of the main plates (3) causing, because of raising and lowering mechanism (6), translation movement of the central plate (5) according to an axis perpendicular to the plane defined by the main plates (3), from a low position in which said central plate (5) is arranged below the main plates (3) and is retracted by the latter to a high position in which it is placed in the plane of said main plates (3) at the level of the central space (51), the central plate (5) now forming a full plate with the main plates (3).
