A folding closure device is fit to be associated to the edges of an opening or passage and comprises at least a plurality of elongated elements (2).
Each elongated element (2) has at least a longitudinal side (5, 7) rotatingly connected by hinge means (3, 4) to a longitudinal side (5, 7) of an adjacent elongated element (2).
Said elongated elements (2) are movable between an opening condition of the passage, in which said elements (2) are, or are almost, mutual faced and a closing condition of said passage in which the elements (2) are coplanar or almost coplanar.
A longitudinal sliding side (5) of each elongated element (2) is associated in sliding manner to at least a guiding means (6).
The rotation axes of the hinge means (3) of the longitudinal sliding sides (5) of the elongated elements (2) define a respective fixed geometric plane and the rotation axes of the hinge means (4) of opposite longitudinal sides (7) of said elements (2) define a movable geometric plane more distanced from the at least a guiding means (6) in respect to the fixed geometric plane in any condition, also in closing condition, of the device (1).

  • A drawback of said known devices consists in that when they are in the closing condition of a space or room, it becomes difficult to open the devices and often it needs to use two hands or it needs to apply manually a rotation torque of the first element which renders their opening difficult and disadvantageous.
  • Other drawbacks of the known folding devices consist in that they let the air and light pass through, that, generally, they are not sufficiently robust and safe.
  • An object of the present invention is to propose a folding closure which can be opened in an easy manner without excessive efforts and that it is simple and reliable.
  • Other object is to propose a device that, in the closing condition, it blocks light and dust.
  • Further object is to propose a safe and robust device which is suitable to carry out either lockings or elements for furniture.
  • The characteristics of the invention are evident in the following with detailed reference to the attached drawings, in which:
    • figure 1 shows a frontal view of the folding closure device, object of the present invention, in a closing condition;
    • figure 2 shows a sectioned view at the plane II - II of figure 1;
    • figure 2b shows a partial and enlarged view of figure 2;
    • figure 3 shows a partial and sectioned view at the plane III - III of figure 1;
