Definitions

  • the present invention concerns an improved device for opening and closing folding doors of a furniture cabinet.
  • the invention also relates to the furniture cabinet provided with these folding doors.
  • the field of the invention relates to systems used to open and close doors with a folding movement, for wardrobes, kitchen cabinets and other cabinets for furnishing in general.
  • Conventional doors with a folding movement have a first door hinged to a shoulder of the cabinet, provided with upper trolleys and lower runners that engage in respective sliding tracks positioned inside said cabinet.
  • a second door is hinged to this first door, which is also provided with upper trolleys and lower parts sliding on the same tracks used for the trolleys and runners of the first door.
  • Prior art folding doors as described above, have the drawback that, even in their completely open position, they are arranged at around 90° with respect to the inner compartment of the cabinet, causing the formation of an obstruction that prevents the compartment of the cabinet to be fully used.
  • German patent application DE19646199A1 describes a folding door consisting of two panels that can rotate relative to each other.
  • a drive motor is connected to the first panel that has a fixed pin support.
  • the motor is arranged in an external guide close to the upper edge of the first panel, so that it can translate between two limit stops.
  • It is connected to at least one flexible driving element, through an element that slides by means of at least one of its vertical shafts.
  • the driving element is arranged in a horizontal curved guide, fixed to a fixed structure above the upper edge of the first panel, at a level such that it does not limit the movement of the door.
  • the Japanese utility model JPS5982186U describes a folding door formed by two panels connected so that they can be folded freely at the adjacent edges on the room side; a panel of the door has its free end fixed in a rotating manner to the upper and lower frames and the end of the other panel is free.
  • the panels are movable along the guide tracks of the upper and lower frames.
  • the guide track of the lower frame is located in the end part of the track in the position of the end part of the pin of the door spring housing.
  • the panel is rotatable towards the outside of the room and the hinged end of the panel is rotated by a drive motor.
  • the main object of the present invention is to provide a new device suitable to allow doors with a folding movement to be able to rotate up to an angle of above 90° on the related shoulder of the cabinet, so as to avoid the formation of obstructions in the inner space of the compartment thereof.
  • a further object of the present invention is to provide a device that is reliable and long lasting.
  • the device of the invention makes it possible to overcome the conventional need to provide tracks inside the cabinet, so as to allow folding doors to slide until the compartment for access to the inside of the cabinet is completely free.
  • the device of the invention is used to guide the opening and closing movements of two folding doors, a first door 2 and a second door 3 respectively, used to close the compartment 4 of a cabinet 5.
  • the first door 2 is hinged, on its side 2a, to the shoulder 6 of the cabinet 5 by means of hinges 7, of the type designed to allow the door to open up to 180° with respect to the initial position closing the compartment 4 of the cabinet 5 ( Fig. 8 ).
  • hinges 7 are of the type described and illustrated in the patent application IT102016000012259, filed on 5 February 2016 by the same Applicant.
  • the side 2b of the door 2, opposite its hinging side 2a, is instead hinged to the corresponding side 3b of the second door 3 by means of central hinges 31, preferably of spring loaded thrust type, suitable to facilitate the folding opening and closing movements of the door 3 on the door 2.
  • the side 3a of the door 3, opposite its side 3b, is instead provided, at its upper end 8, with the guide arm 9 of the device 1 illustrated in Figs. 2 and 3 .
  • the device 1 of the invention is mounted fixed above and on the outside of the top 13 of the cabinet 1 and comprises a central guide 10 extending rectilinearly, at the opposite ends of which respective curvilinear or arched guide sections, 11 and 12 respectively, are mounted.
  • the device 1 has a separable structure, in which the guides 10, 11 and 12 are not in a single piece but are separate from one another.
  • the guide arm 9 of the device of the invention has an L-shaped bracket 14 that, on the vertical side, is fixed to the upper end 8 of the door 3, while on the horizontal side it is hinged, by means of a pin 15 engaged in a respective hole 17a, on a first metal tab 16, bearing the hole 17b for passage of the pin 15. This allows rotation of the door 3 with respect to the door 2 in the direction of the arrows F1 in Fig. 5 .
  • the same tab 16 is also provided with holes 18, 19 and a slot 20 oriented crosswise with respect to the same axis.
  • the guide arm 9 further comprises a second metal tab 21 fixed superimposed on the first tab 16 by means of pins 22, 23 suitable to be inserted sliding in the corresponding slotted holes 24, 25 of the tab 21.
  • the same tab 21 also has a hole 26 suitable to receive the stud 27 of an eccentric 28, inserted in the slot 20 of the tab 16.
  • the arrangement described allows the tab 21 to translate longitudinally with respect to the tab 16 in the direction of the arrows F2 in Fig. 4 .
  • the end of the guide arm 9 facing the guides 10, 11, 12 of the device of the invention is provided with sliding means, which, in the example illustrated in Figs. 4 and 5 , consist of bearings 29 and 30 that engage sliding inside the aforesaid guides 10, 11 and 12.
  • both the doors 2 and 3 move away from the cabinet 5 by sliding of the bearings 29, 30 of the guide arm 9, first in the direction of the arrow F4 in Fig. 6 , inside the curvilinear guide section 12, and subsequently in the direction of the arrow F5 in Fig. 7 , inside the rectilinear central guide section 10.
  • the guides 10, 11, 12 and the arm 9 of the device of the invention could also be underneath or on the outside of the base 32 of the cabinet 5, as illustrated in Fig. 10 .
  • the objects of the invention are achieved also arranging the device 1 on the surfaces of the top 13 and of the base 32 facing the inside of the compartment 4 of the cabinet 5, thanks to the presence of the described composition with arched or curvilinear ends of the sliding guide of the bearings 29, 30, at the sides of the rectilinear section of the device 1.
