Assembly for opening/closing of wings through synchronized motion

An assembly for opening and closing doors comprising at least a first door, a second door and a mechanism adapted to move said doors from a closing position, wherein said doors lie superimposed on a same substantially vertical plane, to an opening position wherein said doors are arranged facing each other and lying on two parallel and substantially horizontal planes, and vice versa, said doors being movable through a synchronized rotary-translating motion operated in the same direction when passing from said closing position to said opening position, and vice versa,

• wherein said mechanism comprises a first and a second kinematic device respectively adapted to move said first door and said second door, said first and second kinematic devices being separate and distinct, and wherein said assembly further comprises a mechanism for synchronizing the rotary-translating motion of the doors and changing a ratio of transmission of the rotary-translating motion of the doors, thereby imparting differential trajectories to the synchronized motion of said first door with respect to said second door in the rotary-translating motion between said closing position to said opening position and vice versa, kinematically connecting said first and said second kinematic device;
• wherein said first and second kinematic devices each comprise pairs of elements symetricall arranged adjacent opposite sides of said first and second doors said elements comprising respectively, on each side,
• a first and second transmission mechanism;
• a first and a second sliding member slidingly movable within a guide groove to pass from said closing position to said opening position, and vice versa, said guide groove being associable to a vertical side of a compartment closable with said first and second doors, said first and second doors being rotatably mounted on the respective sliding member, around a first and a second pin, respectively;
• a first plurality of transmission elements and a second plurality of transmission elements;
• a first and a second counterbalancing mechanism;
• and
• a first arm rotatably associable to said second side and to said first door at the respective ends, and a second arm rotatably associable to said second side and to said second door at the respective ends.
