Definitions

  • the object of the present invention is an easily transported and assembled wall structure with or for sliding door.
  • the door slides between two extreme positions, a closed position and an open position, while maintaining its own lying plane constant (or parallel to itself), and is supported by a sliding rail whereupon at least two carriages are engaged, which are attached to a horizontal edge of the door.
  • the door slides along a sliding track, while at the same time it rotates its own lying plane about an axis of rotation which, generally speaking, is carried by the carriage supporting the door onto the sliding track.
  • the door is composed by a plurality of wings (or segments) hinged to one another at their vertical edges to define a series of rotation axes. Passing from the closed configuration to the open configuration, when the folding door is being folded to an accordion-like shape at a side of the wall structure, the various wings of the folding door rotate about said rotation axes. Each individual wing therefore undergoes a slide-swinging movement which is analogous to the movement of a single slide-swinging door; one of the two rotation axes of each wing is carried by a respective carriage which, in turn, is engaged with a sliding track supporting the door.
  • Various wall structures with sliding doors are known.
  • One of these for example, comprises a preformed element of parallelepiped shape to be associated with the perimetral elements of the wall structure and having a seat for receiving the sliding door during its movement.
  • the wall panels of the structure (for example of plasterboard) are fixed to said element by screws or equivalent members. Those regions in which said screws are inserted into the wall panels are then suitably plastered over.
  • This known arrangement has various drawbacks such as the large dimensions of the preformed element (at least equal to those of the sliding door), resulting in obvious problems in terms of transport, weight and handling during the assembly of the wall structure. Because of the dimensions of the preformed element, the method of its fixing to the wall panels and the transport difficulties, several persons (at least two) are required for assembling the wall structure, so negatively affecting the assembly cost. In addition, this known arrangement only enables wall structures of predetermined dimensions to be obtained, each requiring an appropriate preformed element of suitable dimensions. This means that a provider of such structures must necessarily stock elements of all possible dimensions, resulting in very high storage costs.
  • Another known arrangement is applicable in particular when the frame of the building into which the aforsaid structure is to be inserted is mainly of wooden beams.
  • elements also of wood
  • This arrangement also has various drawbacks, including the fact that it can be used only for particular sizes of wall structure and only in buildings having a wooden beam frame.
  • several persons are necessary to assemble the structure with the sliding door, so implying a considerable assembly cost.
  • Document US 4,561,210 illustrates a wall structure for sliding doors which can be used also when the walls are composed by pairs of mutually facing, parallel panels, in particular prefabricated and/or plasterboard panels. It comprises a perimetral frame where a pair of uprights connects a top longitudinal member having an inverted "U" shaped cross section, with a bottom lungitudinal member which has an inverted "U” shaped cross section and is interrupted in correspondence with a wall opening to be closed by the sliding door.
  • a door housing case is made by fixing a plurality of mutually facing vertical elements to both the top and bottom longitudinal element (and then covering the same plurality of elements by means of plasterboard panels or similar panels).
  • each vertical element is inserted in a correspondingly shaped hole of a given size which is made in the horizontal face of the top element.
  • the bottom end of each vertical element is suitably shaped into a structure featuring two arms, so as to be engaged in a "fork-like" manner with one of the vertical flanges of the bottom longitudinal element and fixed thereto by means of screws.
  • the sliding rail whereupon the sliding door support wheels (or carriages) are engaged, is fixed by screws onto the end of two further uprights which are fixed to the bottom longitudinal element and are fixed by screws onto the top longitudinal element.
  • the vertical elements must be located at positions which are rigidly imposed by the shaped holes where the top ends of the vertical elements must be inserted, said holes having to be previously made into the central face of the top longitudinal element when this latter is produced. Furthermore, for fixing the bottom ends of the vertical elements to the bottom longitudinal element, a complex and specific processing of the bottom end itself is required. In addition, support for the sliding rail is obtained in a laborious way.
  • Document EP 0 751 275 B1 discloses a wall structure of the type illustrated in US 4,561,210 , which is semplified and improved to eliminate some of the drawbacks of the latter.
  • the sliding door housing case is defined by pairs of vertical elements, whose bottom and top ends are identical to each other and have a shape enabling them to be engaged in a "fork-like" manner with the vertical flanges of the bottom longitudinal element: in such a way, during assembly, the vertical elements are symmetrical with respect to exchanging their top part with their bottom part.
  • the wall structure further comprises a set of guide means which is composed during assembly by cutting it at the required size.
  • Said set of guide means comprises a support element and a sliding rail. The latter is fixed to a face of the support element.
  • a pluralty of strip-like spring clips of omega shape To the face of the support element opposed to the one where the rail is fixed, there is also applied a pluralty of strip-like spring clips of omega shape, whose opposing lugs are bent towards the interior of the support element. Coupling the strip-like spring clips with the top longitudinal element allows a stable connection between the latter and the rail before finally fixing the position of the rail with related screws, thus simplifying the rail assembly step.
  • each vertical element does not reach the top longitudinal element, but abuts a respective side face of the rail support element.
  • the wall structure assembly operations are simplified and a certain freedom in applying the same system to sliding doors of different widths is allowed (in particular, thanks to the possibility of making the vertical elements freely slide along the bottom longitudinal element before definitely fixing them), also this solution is not free from drawbacks.
  • the wall structure is not directly applicable to sliding doors of different heights: the processing of the ends of the vertical elements which is necessary for their engagement with the bottom longitudinal element, in fact, makes the application of those same vertical elements to doors of different heights impossible, thus making it necessary to produce and stock vertical elements of different lengths.
  • a further drawback is that fitting the structure on walls of different thicknesses, in particular on perimetral frames having horizontal longitudinal elements of different widths, is difficult, if not impossible. Furthermore, the strip-like spring clips located onto the rail support element cannot be easlily fitted on longitudinal elements having different widths (where the term width is referred to the thickness of the wall the door is to be applied to). In fact, by exploiting the elasticity of the opposing lugs of the "omega" shape" of the strip-like spring, it is possible to only partially cope with small variations of the longitutinal element width (specifically, with small variations of the thickness of the related wall).
  • Document US 4 742 645 A illustrates a wall structure which may be inserted into a perimetral frame made by a top longitudinal wooden member and two vertical wooden uprights.
  • the wall structure comprises a sliding track which is located on top.
  • Two pairs of vertical elements are associated to the sliding track and define the sliding door housing case.
  • Each of said vertical elements is made by a metal profile having an "omega-like" transverse section inside which a related long lumber piece is axially inserted.
  • the lumber piece fills the whole transverse section of the profile along the whole length of the profile itself, exception made for two side spaces which develop along the whole length of the same profile.
  • Connection between each vertical element of the wall structure and the sliding track is obtained by using a corresponding shaped bracket which, in turn:
  • Document EP 2 299 043 A1 illustrates a wall structure which may be inserted in a perimetral frame made by a metallic top longitudinal element and by two metallic vertical uprights.
  • the sliding door housing case is defined by the wall structure by means of a single top longitudinal element having a reversed "U" cross section, and by two pairs of vertical elements.
  • snap-like fixing means are integrated into the top longitudinal element at predetermined positions, for fixing the vertical elements to the top longitudinal element. The position of any vertical element along the top longitudinal element is therefore fixed by the location of the corresponding snap-like fixing means.
  • a sliding track is slidingly inserted into the reversed "U" cross section of the top longitudinal element and fixed therein at a predetermined position by the interaction between reference notches provided on the sliding track and corresponding reference teeth provided into the top longitudinal element.
  • the so obtained whole set may then be fixed to the perimetral frame.
  • the sliding track is fixed to the vertical uprights of the perimetral frame by means of metal brackets mounted at the ends of the sliding track.
  • the sliding track may then be fixed also to the top longitudinal element of the perimetral frame by means of further metal brackets.
  • An object of the invention is to provide an easily transported and assembled wall structure with or for sliding door which obviates the above mentioned drawbacks.
  • a particular object of the invention is to provide a wall structure the components of which are easily transported, are of small dimensions allowing them to be packaged into a box, and possess a considerable applicational versatility, enabling wall structures of different dimensions to be obtained substantially from the same basic components without particular additional working operations.
  • a further object of the invention is to provide a wall structure which can be easily fitted into walls of different thicknesses, even if starting from the same basic components.
  • a wall structure with or for a door having a sliding movement in particular a sliding door, or a slide-swinging door, or a folding door (this latter being substantially equivalent to a group of slide-swinging doors for the aims of the present description, as already mentioned in the introduction of the present description itself), generally speaking comprises a first set of elongated constructional elements 21, destined to be operatively connected to a peripheral frame 1 to define guide means 12 (in particular, at least a rail section 21 to be connected to a horizontal part 3 of the peripheral frame 1) for guiding the door along its sliding movement.

  • Wall panels 14, 15 are destined to be fixed to opposing faces 7, 8 of said interconnected elongated elements.

  • Each of these latter has a "C" shaped cross section and comprises an intermediate part 6 from which flanges 7 and 8 project from its lateral edges (in particular, in a non-limiting embodiment, the related opposing faces 7, 8 of the interconnected elongated elements of the peripheral frame 1 are obtained on these flanges).
  • the width of the structure span may be changed in a known way by using a a second peripheral element 3 of different length and/or by fixing it in a different position with respect to the first 2 and third 4 peripheral element.
  • the second peripheral element 3 is located on top (specifically: in lintel position, as a top longitudinal element).
  • the height of the structure span may be changed in a known way, by using a first 2 and a second 4 peripheral element of different length.
  • an easily transported and assembled wall structure with or for sliding door comprises elongate constructional elements 21, 10, 10A, 11, 11A destined to be operatively connected to a peripheral frame 1.

  • a first set of said elongate constructional elements 21 defines guide means 12 for guiding the door 16 during its sliding movement.
  • the door 16 slides along the guide means 12 via wheels 17 fixed to the door by usual fixing elements 18.
  • At least a known brake 20 is provided to counter the free movement of the wheels along the guide means 12.
  • the guide means 12 comprise at least a rail section 21 to be connected to a horizontal part 3 (specifically, in particular, the second peripheral element 3) of the peripheral frame 1.
  • This is also fitted to several types of doors 16 and could even comprise only the first set of elongated constructional elements (indicated above by the reference numeral 21), which defines the guide means 12.
