An opening/closing device (1) is described in the form of an articulated pentalateral with two centres of rotation (17,18) connected to each other by means of gears, able to open/close a flap door (2) of an item of furniture (3) and comprising a support (4) to which are hinged at least a first and a second arm (5, 6) coupled to each other by means of two toothed areas (7, 8) formed on the outer surfaces of the ends of the first arm (5) and of the second arm (6), which are hinged to the support (4) by means of pivots which form the above centres of rotation (17, 18). One end of the element (9) which carries the flap door (2) is hinged to the other end of the second arm (6) by means of a pivot forming the axis of rotation (11) of the flap door (2): on opening of the flap door (2) the second arm (6) is made to rotate towards the outside of the item of furniture (3) by rotation of the first arm (5), shifting the axis of rotation (11) of the flap door (2) towards the outside of the item of furniture (3) and allowing opening thereof even if the flap door (2), when closed, is superimposed on the upper part of the frame of the item of furniture (3). |
