  • the present invention relates to a supporting device for sliding doors according to the characteristics of the pre-characterizing part of claim 1.
  • the present invention also relates to a door comprising the supporting device of the invention according to the characteristics of the pre-characterizing part of claim 24.
  • the present invention also relates to a piece of furniture comprising the supporting device of the invention according to the characteristics of the pre-characterizing part of claim 25.
  • the terms "front” and “at the front” refer to the opposite side of the piece of furniture with respect to the side of the piece of furniture that is usually placed next to the wall and the terms “back” and “at the back” refer to the side of the piece of furniture that is placed next to the wall, namely the opposite side with respect to the front side of the piece of furniture.
  • the term “lateral” refers to the parts of the piece of furniture commonly called sides of the piece of furniture.
  • door must be understood as referring to a generic panel for closing a corresponding space that is made concealed or accessible by opening the panel itself.
  • Solutions are known in which a piece of furniture is equipped with several guides in which different doors slide in such a way as to allow the overlap of a door with respect to the adjacent one because one of the doors always slides on a plane spaced at the front or at the back with respect to the adjacent door.
  • the patent application WO 2010/038127 A2 describes an opening mechanism that includes a longitudinal guide that is fastened to the frame of a piece of furniture and that, for each of the doors, further includes a first slide sliding along the longitudinal guide and a second slide that supports the door and that slides transversely on the first slide from a retracted position to an extracted position and vice-versa, and return means to bring the second slide in the retracted position.
  • the patent application WO 2012/049667 A1 describes a mechanism for moving the doors of a piece of furniture in a coplanar way that comprises at least one moving unit for moving at least one of the doors, this moving unit comprising a supporting element which is mobile in a longitudinal direction and a connection bracket supported by the supporting element and connectable to the door, the mechanism further comprising a guiding element for guiding the bracket between a first coplanar position and a second non-coplanar position.
  • the patent application US 2012/066978 A1 describes a device for moving doors which includes a straight guide that can be installed along the width of an opening closable by means of a door, a first carriage slidingly mobile along the straight guide and connected to a connection element fixable to the door, an auxiliary carriage connected to the connection element, wherein said auxiliary carriage is free to slide in a direction substantially perpendicular to the straight guide.
  • the patent application WO 2009/043701 A1 describes doors that are able to slide with respect to each other and that are intended to be placed on each other's side on a common vertical plane, such doors including laterally sliding means, a pair of lower or upper guides having different lengths, in which such guides are curvilinear and extend parallel to each other with different bending radii, the doors being equipped with connection elements and rotation pins with respect to a supporting plate.
  • the conditions in which the doors are left in a condition in which they are not closed correctly can, in some cases, also be an obstacle to the opening of other doors of the piece of furniture, which may be subject to a condition of interference with the door that was not closed correctly.
  • the aim of the present invention is to provide a supporting device for sliding doors that enables an effective closing of the space of the piece of furniture.
  • First of all the solution according to the present invention allows to obtain a piece of furniture in which the internal space is accessible by means of sliding doors that can close effectively the space itself preventing the presence of too many gaps that may let dust or dirt in.
  • the solution according to the present invention prevents the problem related to the fact that the door could be left in a partially open position, facilitating the return of the door itself to the correct closed position.
  • the present invention relates to a supporting device for sliding doors (2) for closing at least one space (38) of a piece of furniture (3) in which the door (2) is supported by a trolley (1) sliding on guiding means.
  • the trolley (1) includes a bracket that constitutes the support of the door and said bracket is mobile ( Fig. 1 ) according to a direction of extraction and/or insertion (40) at least partially inclined with respect to the sliding direction (37) of the door (2) that corresponds to the movement of opening of the space (38) concealed by the door (2).
  • the inclination according to which the movement of the door (2) occurs according to the direction of extraction and/or insertion (40) is an essentially transverse direction with respect to the sliding direction (37) so that before the sliding of the door in the sliding direction (37), the door (2) is moved away from the body of the piece of furniture (3) according to said direction of extraction and/or insertion (40) and orthogonally with respect to the sliding direction (37), separating the door (2) from the closing contour of the space.
  • the piece of furniture (3) is equipped with two doors (2) and, therefore, in the opening phase of one of the two doors, it slides laterally placing itself in a condition of overlap with the other door that remains closed.
  • there is a number of doors higher than those shown will also be possible.
  • the present invention relates to a supporting device (36) for at least one sliding door (2) for closing at least one space (38), in which the supporting device (36) includes guiding means (4) essentially parallel to the width extension of the body of the space.
  • the guiding means (4) are intended to guide the sliding of a trolley (1) that supports the door (2), the sliding occurring according to a sliding direction (37) essentially parallel to the width extension of the body of the space.
  • the trolley (1) includes a plate (14) equipped with wheels (15, 16, 17, 18) intended for the sliding in a condition of coupling with the guiding means (4).
  • the plate (14) supports a bracket (13) intended to support the door (2).
  • the bracket (13) is, as previously observed, a bracket mobile with respect to the plate (14) according to a direction of extraction and/or insertion (40) at least partially inclined with respect to the sliding direction (37).
  • the movement of the bracket (13) with respect to the plate (14) is driven ( Fig. 10 , Fig. 11 ) by means of coupling devices (25, 26, 27, 28) between at least two positions of which:
  • the coupling devices (25, 26, 27, 28) that guide the movement of the bracket (13) with respect to the plate (14) include ( Fig. 10 , Fig. 11 ) at least one slot (25, 26) and at least one pin (27, 28), in the case shown, that is to say, in the preferred embodiment of the present invention there being two slots and two corresponding pins.
  • the at least one slot (25, 26) constitutes a guiding profile within which the movement of the corresponding pin (27, 28) is guided.
  • the slot (25, 26) is of an oblong shape with a longitudinal extension essentially parallel with respect to the direction of extraction and/or insertion (40) as it is the slot that determines the direction of extraction and/or insertion (40) and its inclination with respect to the sliding direction (39).
  • the coupling devices (25, 26, 27, 28) that guide the movement of the bracket (13) with respect to the plate (14) include a first slot (25) and a second slot (26) respectively coupling with a first pin (27) and a second pin (28), in which the first slot (25) constitutes the guiding profile within which the movement of the first pin (27) is guided and in which the second slot (26) constitutes the guiding profile within which the movement of the second pin (28) is guided. Therefore, the first slot (25) and the second slot (26) form a pair of reciprocally parallel guiding profiles.
  • the pin (27, 28) is made ( Fig. 10 , Fig. 11 ) in the form of a bearing or roller whose perimeter is intended to slide with a rotation of the bearing itself along the inner edge of the corresponding slot (25, 26).
  • the slot or slots (25, 26) can be obtained in correspondence of the bracket (13), while the corresponding pin or pins (27, 28) will be fastened on the plate (14).
  • the slot or slots (25, 26) are obtained on the plate (14) and the pin or pins (27, 28) are fastened on the bracket (13).
  • the coupling devices that guide the movement of the bracket (13) with respect to the plate (14) further include ( Fig. 10 , Fig. 11 , Fig. 17, Fig. 18 ) two circular plates (19, 20).
  • Each circular plate (19, 20) is rotationally fastened to the plate (14) in a corresponding hinging point (21, 22) and the bracket (13) is fastened to and is integral with the circular plate (19, 20).
  • the slot (25, 26) is in the shape of an arc of a circle with the centre corresponding to the hinging point (21, 22) of the circular plate (19, 20).
  • the rotation of the circular plate (19, 20) involves the movement of the bracket (13) with respect to the plate (14) between the two described positions, that is to say, the first position in which the bracket (13) is in an essentially retracted condition and the second position in which the bracket (13) is in an essentially extracted condition.
  • the coupling devices that guide the movement of the bracket (13) with respect to the plate (14) include two circular plates (19, 20).
  • a first circular plate (19) is rotationally fastened to the plate (14) in a corresponding first hinging point (21).
  • a second circular plate (20) is rotationally fastened to the plate (14) in a corresponding second hinging point (22).
  • the bracket (13) is fastened on the circular plates (19, 20) in correspondence of the pins (27, 28), made in the form of bearings.

  • the movement of rotation of the circular plates is guided by the slots and the fastening of the bracket on the pins in the form of bearings allows to obtain an at least partial counter-rotation of the bracket therefore keeping the door essentially parallel to itself during the movement between the first position and the second position, or vice-versa during the movement between the second position and the first position.
  • the at least two circular plates (19, 20) are connected to each other by means of a rod (23) hinged on the circular plates (19, 20) themselves.
  • the rod (23) coordinating the rotation of the corresponding circular plates (19, 20) reciprocally restraining the rotation of the latter according to corresponding angles of rotation. In this way one prevents possible jamming due to a rotation also slightly different between the two circular plates.
  • at least one of the circular plates (19, 20) comprises a notch (51) in correspondence of at least one perimeter portion of the circular shape.
  • a lever (50), on which a first elastic means or first spring (52) acts, is rotationally fastened on the plate (14) by means of hinging.
  • the lever (50) includes an end shaped to interact and couple with the notch (51).
  • the first elastic means or first spring (52) exerts a force on the lever (50) intended to stop the rotation of the circular plate (19, 20) by means of the coupling between the end of the lever (50) and the notch (51).
  • the stopping of the rotation of the circular plate (19, 20) occurs in correspondence of the second position in which the bracket (13) is in an essentially extracted condition so that, when the bracket is in such position and the trolley slides in the guiding means, the return of the bracket is locked and it is firmly kept in the second extracted position.
  • an abutment element (49) constituting a disengagement means of the lever (50) intended to control the rotation of the lever (50) with the consequent disengagement of the coupling between the end of the lever (50) and the notch (51).
  • the abutment element (49) is fastened on the guiding means (4) in correspondence of the position of the trolley (1) along the sliding on the guiding means that is the position in which the bracket (13) passes from the second position in which the bracket (13) is in an essentially extracted condition to the first position in which the bracket (13) is in an essentially retracted condition.
  • the guiding means (4) include ( Fig. 4 , Fig. 5 , Fig. 6 , Fig. 9 , Fig. 16 ) at least one first guide (5) and at least one second guide (6) parallel to each other and extending essentially parallel to the width extension of the body of the piece of furniture (3).
  • the first guide (5) is intended to guide ( Fig. 6 , Fig. 13 ) corresponding first wheels (15) and/or second wheels (16) fastened on the trolley (1).
  • the second guide (6) is provided with a sliding seat (12) intended to guide ( Fig. 6 , Fig. 13 ) corresponding third wheels (17) and/or fourth wheels (18) fastened on the trolley (1).

  • the locking device (24) is integral with one of the coupling devices (27, 28) and the locking device (24) is mobile between the at least two previously described positions, that is to say, the first position in which the bracket (13) is in an essentially retracted condition and the second position in which the bracket (13) is in an essentially extracted condition.
  • the locking device (24) In the second position the locking device (24) enters a locking seat (11) obtained on the third guide (7) and the sliding of the trolley (1) on the guiding means (4) involves the sliding of the locking device (24) within said locking seat (11) with the corresponding locking of the bracket (13) in the second position in which the bracket (13) is in an essentially extracted condition preventing the movement of the bracket (13) towards the first position during the sliding of the trolley (1) on the guiding means (4).

  • the fifth wheel (24) is pivotally applied in correspondence of an end of one of the first pin (27) and second pin (28). In this way the movement of the corresponding pin will bring the fifth wheel in a condition of insertion within the third guide for locking the movement of return from the second position to the first position of the bracket.
  • the supporting device (36) includes an addressing lock (29) provided with an addressing channel (31).
  • the addressing lock (29) is placed in correspondence of the first position in which the bracket (13) is in an essentially retracted condition. In said position the addressing lock (29) is in a condition in which the locking device (24) is inserted within the addressing channel (31).
  • the addressing channel (31) guides ( Fig. 12 ) the movement of the locking device (24) between the two described positions.
  • the addressing channel (31) is open in correspondence of a surface of coupling with the third guide (7) so that the third guide (7) constitutes the extension of the addressing channel (31) itself and vice-versa the addressing channel (31) constitutes the extension of the third guide (7).

  • the supporting device (36) comprises ( Fig. 4 , Fig. 7 , Fig. 8 , Fig. 14 , Fig.
  • Said damping force (42) opposes the movement of the bracket (13) with respect to the plate (14) between the first position in which the bracket (13) is in an essentially retracted condition and the second position in which the bracket (13) is in an essentially extracted condition slowing down the return in the closed position that occurs ( Fig. 14 ) by means of a second elastic means or second return spring (47) that is wound in correspondence of the second hinging point (22) and acts between a point of fastening on the plate and the second pin (28) to perform the return action.
  • the shock-absorber (42) is a slowdown means in the phase of return of the door (2) upon closing of the latter.
  • the shock-absorber (42) is made up of an oblong pushing arm (33) that is hinged at a fulcrum point (34) arranged between the ends of the pushing arm (33) itself.
  • a pushing means (35) preferably in the form of a piston applying said pushing force (42) on the arm (33) which transmits it to the trolley (1) for the slowdown of the latter in the closing phase.
  • pushing means is made in the form of a piston
  • many other equivalent solutions are possible, for example based on the use of elastic means of any type and that are considered included within the present invention and appended claims, the application of a pushing means (35) in the form of a piston having to be considered illustrative.
  • the presence of the second return spring (47) facilitates the repositioning of the door in the correct closed position because, once the bracket is in the position corresponding to the return position, the second spring (47) withdraws the locking device (24) which thus enters the addressing channel (31) pulling the bracket towards the first closed position of the space (38), while the shock-absorber (42) slows down its effect obtaining a gentle movement of return of the door without sudden movements or impacts.
  • the door, in the closed position is well adherent to the frame of the piece of furniture effectively closing the internal space. If necessary, in order to improve closing, one can also provide gaskets on the abutment profile of the door against the frame of the piece of furniture.
  • the guiding means (4) are curvilinear according to a bending radius having a size much greater than the lengthwise extension of the guiding means (4), the sliding of the door (2) occurring along said curvilinear guiding means.
  • the guiding means (4) can also be rectilinear (solution not shown).
  • the guiding means (4) can be selected from the group consisting of:
  • the trolley (1) is supported by said guiding means (4) in a position ( Fig. 13 ) inclined by an angle (a) with respect to the sliding plane of said trolley (1).
  • said inclination is opposite with respect to that shown so that the weight of the door tends to keep the door itself in a closed position, that is to say, in the first position.
  • the angle (a) is between 0 degrees and 45 degrees, even more preferably between 0 degrees and 30 degrees, the preferred value being between 0 degrees and 20 degrees.
  • Possible greater or smaller inclinations may be preferable according to the weight of the door and to its assembly, in the sense that if the door is very heavy a smaller inclination will be sufficient to obtain the described effect of facilitation of the start of the opening movement, and vice-versa. Similar considerations also apply to the modes of installation of the door on the bracket because the weight force acting on the door will be transmitted to the trolley according to different values depending on said inclination. In the solution with the plate in an inclined position the first wheels, second wheels, third wheels, fourth wheels will be supported by correspondingly angled brackets in order to ensure the correct sliding of the wheels on the guides in a support condition.
  • the shock-absorber as well as the addressing lock are fastened on the support of the guides (8), thus favouring the obtainment of a precise coupling of the various components.
  • the present invention also relates to a sliding door (2) for closing at least one space (38) in which the door (2) is supported by a supporting device (36) made according to the present invention and as previously described.
  • the present invention also relates to a piece of furniture (3) provided with at least one sliding door (2) for closing at least one space (38) in which the door (2) is supported by a supporting device (36) made according to the present invention and as previously described.
