Definitions

  • the following patent application for industrial invention relates to a closing system for door panels, in particular for folding doors, windows, cabinet door panels and the like.
  • Folding doors are largely known on the market, which comprise one or more door panels that are hinged mutually in order to open or close an opening obtained in a wall. When the door panels are in open position, they are stacked along an orthogonal plane relative to the wall. When the door panels are in close position, they are disposed on a parallel plane relative to the wall in order to close the opening.
  • the volume of the door panels stacked in open position partially reduces the width of the passage through the opening of the door. Otherwise said, the passage is not completely free.
  • the door panels project both in the front and in the back, or only in the front relative to the wall, with a cumbersome volume caused by the width of the door panel.
  • EP2839099 discloses a closure system that comprises two wings and one single mechanism composed of an articulated quadrilateral mechanism connected to the fixed structure, to the first wing and to the second wing.
  • such a closure system is not versatile; in fact, it must provide for a different right-hand mechanism or a different left-hand mechanism according to the position of the opening on the right-hand side or on the left-hand side.
  • Such a type of mechanism is designed for operating with a given measurement (the width of the door opening) and cannot be adapted to different measurements.
  • Such an articulated quadrilateral mechanism needs to be provided with a connective rod that is hinged on two plates that are respectively fixed to the second door panel and to an upper crosspiece of the fixed structure.
  • the hinging points of the connective rod are imposed by the dimensions of the articulated quadrilateral mechanism.
  • DE202015003214 discloses a hinge mechanism used to open and close two door panels.
  • the hinge mechanism comprises a first hinge that connects a first door panel to the fixed frame, a second hinge that connects a second door panel to the first door panel, and an articulated unit that connects the second door panel to the fixed frame.
  • the articulated unit comprises a shelf that projects from one side of the second door panel in such a way to face the opening defined by the fixed frame when the door panels are in open position.
  • the articulated unit comprises a lever that is hinged to the fixed frame and to the shelf.
  • the first hinge, the second hinge and the articulated unit are disconnected.
  • the door panels of the door disclosed in DE202015003214 are not completely closed one on top of the other.
  • Such a drawback is caused by the provision of the shelf that projects from one side of the second door panel in such a way as to face the opening defined by the fixed frame when the door panels are in open position.
  • the width of the second door panel is larger than the width of the first door panel to permit a connection between the shelf and the fixed frame. Therefore, when in open position, the second door panel partially closes the opening defined by the fixed frame.
  • FR2448615 discloses an articulated mechanism for moving a folding door, comprising a first hinge that connects a first door panel to a fixed frame, a second hinge that connects a second door panel to the first door panel, and an articulated unit that connects the second door panel to the fixed frame.
  • the first hinge, the second hinge and the articulated unit are not connected.
  • the articulated unit comprises a shelf that projects from one side of the second door panel in such a way to face the opening defined by the fixed frame when the door panels are in open position, a first lever connected to the fixed frame and a second lever hinged to the first lever and to the shelf.
  • the first lever and the second lever are disposed in such a way as to protrude from the opposite side relative to the door panels when the door panels are closed one on top of the other.
  • FR2448615 is impaired by the fact that the door panels do not close completely one on top of the other because of the provision of the shelf. Moreover, because of the fact that the levers project from the opposite side compared to the door panels when the door panels are closed one on top of the other, the mechanism is cumbersome and aesthetically unpleasant.
  • the purpose of the present invention is to eliminate the drawbacks of the prior art by disclosing a closing system for door panels that is characterized by a reduced volume when the door panels are closed, being at the same time reliable, versatile, easy to make and install.
  • the closing system for door panels according to the invention is defined by claim 1.
  • first hinge unit, the second hinge unit and the articulated unit are not connected.
  • Such a mechanism can operate also for different widths of the opening defined by the fixed frame.
  • the parts of the mechanism do not have a predefined direction and can be indifferently used for door panels that open towards the right-hand side or the left-hand side.
  • the closing system (100) comprises:
  • the fixed frame (1) is intended to be fixed to a wall wherein a rectangular opening is obtained.
  • the fixed frame (1) generally comprises a crosspiece (10) and an upright (11) and defines the perimeter of the opening of the wall.
  • the door panels (2, 3) are rectangular and identical, with an area that is equal to half of the area of the opening defined by the fixed frame (1).
  • a mechanism connects the first door panel (2) to the fixed frame and the second door panel (3) to the first door panel, in such a way that the door panels (2, 3) can go from an open position ( Fig. 2 ), wherein the door panels leave the opening defined by the fixed frame (1) open, to a close position ( Fig. 7 ), wherein the door panels close the opening defined by the fixed frame (1).
  • the mechanism comprises:
  • the first hinge unit (C1), the second hinge unit (C2) and the articulated unit (6) are not connected.
  • the first hinge unit (C1) comprises an upper hinge (4) disposed above an upper edge of the first door panel (2) and a lower hinge (7) disposed under a lower edge of the first door panel.
  • the upper hinge (4) of the first hinge unit comprises a first plate (40) and a second plate (41).
  • Each plate (40, 41) has an "L" shape and comprises a long arm and a short arm.
  • the short arms of the two plates (40, 41) are mutually hinged by means of a pin (P1).
  • the first plate (40) is fixed under the crosspiece (10) of the fixed frame near the upright (11).
  • the second plate (41) is fixed on an upper edge of the first door panel (2) near a lateral end of the first door panel (2) in such a way that the pin (P1) is disposed near the lateral end of the first door panel.
  • the upper hinge (4) permits the rotation of the first door panel (2) relative to the fixed frame (1) around the pin (P1).
  • the lower hinge (7) of the first hinge unit comprises a first plate (70) and a second plate (71).
  • the first plate (70) has an "L"-shaped section with a wing (72) disposed on an orthogonal plane relative to the first plate (70).
  • the second plate (71) has an "L"-shape in plan view and comprises a long arm and a short arm. The short arm of the second plate (71) is hinged to the wing (72) of the first plate by means of a pin (P5).
  • the first plate (70) is fixed to the upright (11) of the fixed frame near a lower end of the upright.
  • the second plate (71) is fixed under a lower edge of the first door panel (2) near a lateral end of the first door panel (2), in such a way that the pin (P5) of the lower hinge is disposed near the lateral end of the first door panel and is vertically aligned with the axis of the pin (P1) of the upper hinge of the first hinge unit.
  • the first door panel (2) can rotate in a balanced manner relative to the fixed frame (1) around the axis of the pins (P1 and P5) of the lower hinge and of the upper hinge.
  • the second hinge unit (C2) comprises an upper hinge (5) disposed above an upper edge of the first door panel (2) and of the second door panel (3), and a lower hinge (8) disposed under a lower edge of the first door panel and the second door panel.
  • the upper hinge (5) of the second hinge unit comprises a first plate (50) and a second plate (51).
  • Each plate (50, 51) has an "L" shape in plan view and comprises a long arm and a short arm.
  • the short arms of the two plates (50, 51) are rounded and mutually hinged by means of a pin (P2).
  • the first plate (50) of the upper hinge of the second hinge unit is fixed on the upper edge of the first door panel (2) near a lateral end of the first door panel (2) in distal position relative to the upper hinge (4) of the first hinge unit.
  • the upper hinge (5) of the second hinge unit permits a rotation of the second door panel (3) relative to the first door panel (2) around the pin (P2).
  • the lower hinge (8) of the second hinge unit is substantially identical to the upper hinge (5) of the second hinge unit.
  • the lower hinge (8) of the second hinge unit comprises a first plate (80) and a second plate (81).
  • Each plate (80, 81) has an "L" shape and comprises a long arm and a short arm.
  • the short arms of the two plates (80, 81) are rounded and mutually hinged by means of a pin (P6).
  • the first plate (80) of the lower hinge is fixed under the lower edge of the first door panel (2) near a lateral end of the first door panel (2) in distal position relative to the lower hinge (7) of the first hinge unit, in such a way that the axis of the pin (P6) of the lower hinge coincides with the axis of the pin (P2) of the upper hinge of the second hinge unit.
  • the second door panel (3) can rotate in a balanced manner relative to the first door panel (2) around the axis of the pins (P2 and P6) of the upper hinge and of the lower hinge of the second hinge unit.
  • the articulated unit (6) of the mechanism comprises:
  • the articulated unit (6) of the upper mechanism is provided with two hinges, in the first pin (P3) and in the second pin (P4), in such a way as to follow the movement of the second door panel (3) from the open position of the door panels ( Fig. 2 ) to the close position of the door panels ( Fig. 7 ).
  • the second plate (61) of the articulated unit is fixed on the upper edge of the second door panel (3) near a lateral end of the second door panel (3) in distal position relative to the upper hinge (5) of the second hinge unit, in such a way that the second door panel is stopped against the first door panel when the door panels are in open position.
  • the door panels (2, 3) when the door panels (2, 3) are in open position, the door panels (2, 3) are stacked one behind the other, and the two plates of the upper and lower hinges of the second hinge unit are in parallel position. In such a situation, the two door panels (2, 3) have a reduced volume and are substantially flush with the wall whereon the fixed frame (1) is mounted, without hindering the opening defined by the fixed frame (1).
  • the length of the connective rod (62) is chosen in such a way that the first plate (60) is fixed to the crosspiece (10) in an intermediate position of the crosspiece.
  • the design and the mounting of the mechanism is easy and fast because no complicated calculations are needed to design the first plate (60), with reference to the hinging point of said first plate (60) relative to the crosspiece (10).
