DESCRIPTION

Structure of wall or sliding door easy to transport and assemble.

Technique Field

The present invention relates to a wall structure of or for sliding door easy to transport and assemble.

Some elements, which will be detailed in the following description, can also be used as such separately in wall structures of a different type, for example, with rotary doors or with folding doors; or, in general, said details can be used as such separately to couple sliding rails (or, in general, sliding guide means) in horizontal parts of the perimetral frames of wall structures for doors (specifically, in a crossbar of the in vain where the door would stay).

State of the art

In general, several situations are known in which sliding movement is provided to a door. Specifically, there are three types of doors that respond to these situations: sliding doors, rotating doors, folding doors.

In the case of the sliding door, the door keeps its own inclination plane constant (or parallel to itself) while sliding between two positions at the ends (closed position and open position) and is supported by a sliding rail in the that at least two cars are hooked, which are fixed to a horizontal edge of the door.

In the case of the rototranslating door, during the opening / closing movement, the door slides along a sliding rail and, at the same time, rotates on its own inclination plane around a rotation axis which, in general, It is located in the car that holds the door in the sliding rail.

In the case of the folding door, the door is formed by a plurality of slats (or segments) hinged with one another at the vertical edges to define a series of rotation axes. When moving from the closed configuration to the open configuration, when the folding door is collected as an accordion on one side of the wall structure, the slats of the folding door revolve around said rotation axes. Each lama performs a rototranslation movement that is analogous to the movement of a single rototranslating door; one of the two axes of rotation of each blade is located in a corresponding carriage, which, in turn, engages in a sliding rail that supports the door.

In all these situations there is the problem of coupling sliding rails (or sliding guide means) in horizontal parts of the perimeter frames of wall structures for doors, specifically, in a crossbar of the opening where the door would be housed.

Specifically, for the sliding doors (and, especially, when the door, once opened, must be hidden inside a respective housing), there is the problem of how to make the structure of the frame necessary to hold and / or house the door itself .

Several wall structures with sliding doors are known. One of them, for example, consists of a preformed parallelepiped element that is associated with the perimetral elements of the wall structure and which has a seat where the sliding door is housed during its movement. The wall panels of the structure (for example, of plasterboard) are fixed to said element by screws or equivalent organs. Next, the areas in which said screws are inserted into the wall panels are properly revoked.

This known solution has several drawbacks, such as the large dimensions of the preformed element (equal, at least, to those of the sliding door), which leads to obvious problems of transport, weight and handling during the assembly of the wall structure. Because of the dimensions of the preformed element, the method of fixing to the wall panels and the difficulties of transport, several people (two as a minimum) are needed to assemble the wall structure, which negatively affects the assembly costs. In addition, this known solution only allows to obtain wall structures of predetermined dimensions, each of which needs a suitable preformed element, of suitable dimensions. This means that the supplier of these structures must necessarily have items of all possible dimensions in stock, which entails very high inventory costs.

Finally, because of the dimensional limits of known wall structures, it is not possible to make structures of special non-standard dimensions.

Another known solution is applicable in particular in cases where the framework of the building in which the above structure is to be installed is made mainly of wooden crossbars. In that case, once the position in which the structure is to be located with the sliding door is chosen, elements (also made of wood) that define the opening where said door will be placed and the cardboard wall panels are fixed on said crossbars Plaster are fixed to them. This solution also has several drawbacks, including the fact that it can only be used for wall structures of certain sizes and only in buildings equipped with wooden crossbars. In addition, it takes several people to mount the structure with sliding door, which entails a remarkable assembly cost.

In US 4,561,210 a wall structure for sliding door is illustrated that can also be used on walls formed by pairs of parallel panels, mutually facing each other, namely, prefabricated panels and / or plasterboard plates. It consists of a perimeter frame in which a pair of vertical uprights connects an upper longitudinal cross-sectional element in the form of an inverted "U" with a lower longitudinal cross-sectional element in the form of an inverted "U" and is interrupted in correspondence with a opening in the wall that must be closed by the sliding door. To receive the sliding door when it is placed in an open position, a housing box is made, fixing a plurality of vertical elements, mutually facing each other, in the upper and lower longitudinal elements (and then covering said plurality of elements with plasterboard or similar panels). The upper end of each vertical element is inserted into a hole correspondingly, with a given size, practiced on the horizontal face of the upper element. The lower end of each vertical element is suitably modeled to create a two-arm structure that engages as a "fork" in one of the vertical flanges of the lower longitudinal element and is fixed in it by screws. The sliding rail, in which the support wheels (or carriages) of the sliding door are engaged, is screwed on the end of two other vertical uprights fixed to the lower longitudinal element and screwed to the upper longitudinal element. Although it eliminates the problem of the overall dimensions of the preformed element, this solution has several drawbacks that include the fact that it can only be used in wall structures of certain dimensions. Specifically, the vertical elements must be placed in positions that are strictly imposed by the shaped holes in which the upper ends of said vertical elements are inserted, and said holes will have been previously made on the central face of the upper longitudinal element during the manufacture of the latter. In addition, to fix the lower ends of the vertical elements to the lower longitudinal element, a specific and complex machining of the lower end itself is required. In addition, the sliding rail support mode is very laborious.

EP 0 751 275 B1 shows a wall structure of the type illustrated in US 4,561,210, which has been simplified and improved to eliminate some of the inconveniences it presents. In particular, the housing of the sliding door is defined by two pairs of vertical elements whose lower and upper ends are identical to each other and whose shape allows them to be engaged as a "fork" in the vertical flanges of the lower longitudinal element; In this way, during assembly, the vertical elements are symmetrical in case of exchanging their upper and lower parts.

The wall structure also consists of a group of guiding means that is made during assembly, cutting it to size. Said guide means group consists of a support element and a sliding rail. The latter is fixed to one side of the support element. On the face of the support element opposite the face on which the rail is fixed, a plurality of laminar spring hooks in the form of omega are also applied, whose opposite fins are folded into the support element. By coupling the laminar spring hooks in the upper longitudinal element, a stable connection is formed between the latter and the rail, before fixing the rail in its final position by means of the corresponding screws, which simplifies the rail mounting phase.

The upper end of each vertical element does not reach the upper longitudinal element, but comes into contact with a respective side face of the rail support element. Taking advantage of the «fork» coupling between the lower end of the vertical element and the vertical flange of the lower longitudinal element (and holding the upper end manually on the side face of the rail support element) —before fixing everything with the screws— It is possible to slide the vertical elements freely along the lower longitudinal element, modifying the size of the housing box corresponding to the width of the door as preferred. Once the correct location of the vertical elements has been found, to guarantee the stability of the position, its ends are locked in the rail support element and in the vertical flanges of the lower longitudinal element respectively, using the corresponding fixing screws. Although the assembly operations of the wall structure are simplified and some freedom of application of the same system is offered on sliding doors of various widths (specifically, thanks to the possibility of sliding the vertical elements freely along the lower longitudinal element before fix them definitively), this solution is also not free of inconveniences. Specifically, the wall structure cannot be applied directly to sliding doors of different heights: in fact, the machining of the ends of the vertical elements, which is necessary for coupling in the lower longitudinal element, makes it impossible to apply such vertical elements in doors of different heights, so it is necessary to manufacture and have in stock vertical elements of different lengths. Furthermore, by moving the vertical elements along the lower longitudinal element before finally fixing them to determine their correct position, the upper end of the vertical elements will be

it simply keeps in contact with the rail support element, which allows the vertical element itself to oscillate, moving away from the rail support element, and these oscillations are all the more annoying the higher the door is.

Another drawback is the difficulty, or even impossibility, of adapting the structure to walls of different thicknesses, specifically to perimeter frames with horizontal longitudinal elements of different widths. In addition, the laminar spring hooks located on the rail support element do not easily adapt to the longitudinal elements of different widths (where "width" refers to the thickness of the wall on which the door is to be mounted). Indeed, the elasticity offered by the opposite fins of the "omega shape" of the leaf spring only allows partial adaptation to small variations in width of the longitudinal element (more specifically, to small variations in the thickness of the corresponding wall).

The problem of adapting the hooking device of the gufa system to walls and / or perimeter frames of different thicknesses exists in all wall structures, not only for sliding doors, but also for rotary doors and folding doors and, in In general, for all those wall structures that involve the use of a guiding system that allows the sliding movement of a door and must be fixed to a horizontal part of the perimeter frame. In general, in all these cases, the use of a rail support element, provided with laminar spring hooks such as those described above, does not solve the problem at all. In fact, the laminar spring hooks located on the rail support element do not easily adapt to the horizontal parts of the perimeter frame that have different widths (where "width" means the thickness of the wall on which the wall is to be mounted. door). In fact, the elasticity of the opposite fins of the "omega shape" of the laminar spring only partially adapts to small variations in the width of said horizontal parts (more specifically, to small variations in the thickness of the corresponding wall).

Document US 4 742 645 A illustrates a wall structure that can be introduced into a perimeter frame formed by a longitudinal upper wooden element and two vertical wooden uprights. The wall structure consists of a sliding rail located at the top. Two pairs of vertical elements are associated with the sliding rail and define the housing of the sliding door. Each of said vertical elements is made by a metal profile with a cross section in the form of an "omega", into which a long block of wood is axially inserted. The wooden block fills the entire cross section of the profile along the entire profile, except for two lateral spaces that extend along the entire profile. The connection between each vertical element of the wall structure and the slide rail is made using a corresponding clamp that, in turn:

- in the lower part it is provided with two lateral wings, each of which can be introduced in one of the lateral spaces formed between the wooden block and the profile that constitutes the vertical element;

- in the center it is provided with two slots where to introduce a lateral edge of the sliding rail;

- at the top it is provided with a flat flange that protrudes above the sliding rail. By means of said flat flange (using nails, screws or other similar means), the assembly that includes the slide rail and the vertical elements connected thereto is fixed to the lateral faces of the upper longitudinal wooden element of the perimeter frame.

Document US 4 742 645 A therefore shows all the features of the preamble of claim 1.

EP 2 299 043 A1 illustrates a wall structure that can be introduced into a perimeter frame formed by a metal upper longitudinal element and two metal vertical uprights. The housing of the sliding door is defined by the wall structure, using a single upper longitudinal element with an inverted U-shaped cross section, and two pairs of vertical elements. To fix the vertical elements to the upper longitudinal element, pressure fixing means are incorporated at the ends of the upper longitudinal element and at predetermined positions along said upper longitudinal element. Therefore, the position of any vertical element along the upper longitudinal element is fixed by the location of the pressure fixing means. A sliding rail is introduced by sliding it into the inverted "U" cross-section of the upper longitudinal element, where it is fixed in a predetermined position by interacting between reference notches present in the sliding rail and corresponding reference teeth present in the upper longitudinal element. The complete set obtained in this way can then be fixed in the perimeter frame. Specifically, the sliding rail is fixed on the vertical uprights of the perimeter frame by metal clamps mounted on the ends of the sliding rail. Then, the slide rail can also be fixed in the upper longitudinal element of the perimeter frame by other metal clamps.

Forms of realization of the invention

With reference to the drawings, a wall structure of or for a door provided with sliding movement, namely, a sliding door, or a rotational door or a folding door (the latter being, for the purposes of the present description, substantially equivalent to a group of rotary shutter doors, as already mentioned in the introduction of the present description), usually consists of a first group of elongated construction elements 21, intended to be operatively connected with a perimeter frame 1 to define the grinding means 12 (specifically, at least one rail section 21 that connects with a horizontal part 3 of the perimeter frame 1) to guide the door along its sliding motion.

Generally, the perimeter frame 1 is of the type that has a plurality of interconnected elongated elements,

joined together. The wall panels 14, 15 are intended to be fixed to opposite faces 7, 8 of said interconnected elongate elements. Specifically, said wall panels may be plasterboard or panels made of a similar material. A compartment 41 is defined between said wall panels 14, 15. In the specific case of a sliding door, a door 16 can slide inside said compartment 41 to be housed inside.

The interconnected elongated elements, joined together, which define the perimeter frame 1 consist of a first perimeter element 2, a second perimeter element 3 and a third perimeter element 4. Said first perimeter elements 2, second 3 and third 4 are fixed together. as usual. Each of them has a cross section in the form of "C" and consists of an intermediate part 6 whose lateral edges protrude fins 7 and 8 (in these fins are obtained, specifically, in a non-limiting embodiment, the corresponding opposite faces 7, 8 of the interconnected elongated elements of the perimeter frame 1).

The width of the structure opening can be modified in a known way, using a second perimeter element 3 of different length and / or fixing it in a different position with respect to the first 2 and third perimeter elements 4. Generally, the second perimeter element 3 is located in the upper part (more specifically, in the position of the lintel, as the upper longitudinal element). The height of the structure opening can also be modified in a known way, using a first 2 and second 4 perimeter element of different length.

Specifically, a wall structure of or for sliding door, easy to transport and assemble, consists of elongated construction elements 21, 10, 10A, 11, 11A intended to be operatively connected with a perimeter frame 1.

Said elongated construction elements 21, 10, 10A, 11, 11A are intended to be placed close to said perimeter elements 2, 3, 4.

A first group of said elongated construction elements 21 defines the guiding means 12 for guiding the door 16 during its sliding movement. The door 16 slides through the guiding means 12 thanks to the wheels 17 fixed to the door by means of usual fasteners 18. At least one known brake 20 is provided to counteract the free movement of the wheels along the guiding means 12.

According to the invention, the guide means 12 consist of at least one rail section 21 that is connected to a horizontal part 3 (specifically, specifically, the second perimeter element 3) of the perimeter frame 1. This also adapts to several types of doors 16 and could even consist only of the first group of elongated construction elements (indicated above with reference number 21), which defines the guide means 12. In an embodiment illustrated in the figures, the rail section 21 it is linked to a respective support element 22. The support element 22 of the rail section 21 can be made of wood or other material (for example, of wood-like plastic material). Preferably, in the embodiment illustrated in the figures (see, in particular, figures 6 and 7, among others), the support element 22 of the rail section 21 is made of a single piece with the corresponding rail section 21. Specifically, they can be made together as a single extruded profile.

A plurality of spring hooks 27 are also associated with the guide means 12 prepared to engage the horizontal part 3 of the perimeter frame 1, to couple the guide means 12 to the horizontal part 3 of the perimeter frame 1 before the possible fixing definitive of the guiding means 12 in said horizontal part 3 of the perimeter frame 1, by means of screws or similar means. Specifically, in particular, when the perimeter frame 1 is provided with the elongate elements joined together sf, which consist of the first 2, second 3 and third 4 perimeter element, the horizontal part 3 of the perimeter frame 1 is the second perimeter element 3. Preferably , the second perimeter element 3 is an upper longitudinal element of the perimeter frame 1. In this case, the plurality of spring hooks 27 holds the guiding means 12 in the second perimeter element 3 before the possible definitive fixing of the guiding means 12 in said perimeter element 3. As already stated, said definitive fixation can be made with screws or similar means.

The laminar spring hooks 27 may be the usual "omega" shaped hooks, which consist of a central portion, intended to be fixed in the guide means 12, and of two opposite fins protruding from said central portion away from the means of guide 12 and are folded into the structure in the form of "omega", specifically above the central portion. Preferably, the spring hooks 27 have an innovative shape, more adaptable to walls of different thicknesses (specifically to horizontal parts 3 of the perimeter frame 1 that have a different thickness). The following description of the spring hooks 27 will refer especially to Figures 8 and 10. The spring hooks 27 are of the type consisting of a central portion 27a, coupled to the guiding means 12 on an elongated face 123 of the means guide 12 which is intended to face the horizontal part 3 of the perimeter frame 1. Specifically, specifically, when the guide means 12 consist of at least one rail section 21 and the support element 22 of the rail section 21 (which is preferably made of a single piece with the rail section 21 itself, as mentioned above), the central portion 27a of the spring hitch 27 is coupled to a face of the support member 22 of the rail section 21. Specifically and specifically, the central portion 27a of the spring hitch 27 is placed on the support member 22 on the opposite side of the latter with respect to the corresponding rail section 21. The spring hitch 27 also

it consists of at least two fins 28, 29 located on opposite sides of the central portion 27a with respect to an X axis of the spring hitch 27. The X axis of the spring hitch 27 is intended to coincide with a longitudinal axis of the means of guide 12 when the spring hitch 27 is applied to the guiding means 12 itself. Between its first end 270a, in correspondence of which is one 28 of the two fins 28, 29, and its second end 270b, in correspondence of which the other 29 of the two fins 28, 29 is located, the central portion 27a extends along the X axis of the spring hitch 27 by a plurality of sections 271, which are consecutive to each other and transverse to the X axis of the hitch spring 27 following a zigzag path along the X axis itself of the spring hitch 27. The plurality of consecutive sections 271 performs an accordion structure that can be compressed or extended along the X axis of the spring hitch 27. By compressing the accordion structure along the X axis of the spring hitch 27, the respective extension of said accordion structure is determined perpendicular to the X axis itself, after which the fins 28, 29 of the spring hitch 27 they move away from one another perpendicularly with respect to the X axis itself of the spring hitch 27. By extending the accordion structure along the X axis of the spring hitch 27, the respective contraction of said accordion structure in perpendicular is determined with with respect to the X axis itself, after which the fins 28, 29 of the spring hitch 27 approach each other perpendicularly with respect to the X axis of the spring hitch 27. In this way, taking advantage of the accordion structure of the portion central 27a, it is possible to adapt the spring hooks 27 to the horizontal parts 3 of the perimeter frame 1 of different widths, corresponding to different wall thicknesses.

The hooks 272 are associated with the common ends of the consecutive sections 271 and are intended to be engaged in the guiding means 12. More specifically, the hooks 272 are intended to be engaged in the respective seats 273 present on the elongated face 123 of the means Guide 12. Preferably, the seats 273 for the hooks 272 are made in the form of longitudinal grooves on the elongated face 123. When the seats 273 for the hooks 272 are made in the form of longitudinal grooves in the guide means 12, they can be obtained by means of a single extrusion phase together with the guiding means 12, specifically, together with the rail section 21 and the corresponding support element 22. A respective additional hook 272 ', intended to engage in the guiding means 12, is associated to the first end 270a of the central portion 27a of the spring hooks 27. A respective additional hook 272 '', intended to be engaged in the guiding means 12, is associated with the second End 270b of the central portion 27a of the spring hooks 27. Preferably, the additional hooks 272 ', 272 "of the central portion 27a of the spring hooks 27 are engaged in the same seats 273 made to engage the hooks 272. To use the same guide means 12 (more specifically, the same rail section 21) on walls of different thickness, the elongated face 123 of the guide means 12 may have several seats 273, 273 'for the hooks 272, 272' , 272 "corresponding to different wall widths and / or different widths of the horizontal part 3 of the perimeter frame 1.

The free ends 280, 290 of the fins 28 and 29 of the spring hitch 27 are in a distal position with respect to the central portion 27a and are bent towards the X axis of the spring hitch 27 itself. In this way, at least when look at the spring hitch 27 along its X axis, the "omega" structure of the spring hitch 27 itself is reproduced, which is used to engage in the horizontal part 3 (specifically, specifically, in the second perimeter element 3) of the perimeter frame 1. As specifically illustrated in Figure 10, preferably the spring hitch 27 consists of a metal wire of predetermined length that is folded according to a predetermined scheme to realize at least both the structure of accordion of the central portion such as fins 28, 29. Preferably, the predetermined folding scheme also allows the hooks 272 to be obtained. Preferably, the predetermined folding scheme also allows or get the additional hooks 272 ', 272' '. The metal wire can be made of steel. Preferably, the steel used is of the elastic type. In a preferred embodiment of the invention, specifically illustrated in Figure 10, all the elements of the spring hitch 27 are made with a single folded metal wire according to the predetermined folding scheme. The wire of predetermined length has a first end 274a, which corresponds to the first end 270a of the central portion 27a, and a second end 274b, which corresponds to the second end 270b of the central portion 27b.

More specifically, starting at the first end 274a of the wire of predetermined length and moving towards the second end 274b of the wire of predetermined length, the predetermined folding scheme produces a structure in the wire itself consisting of:

- a first section 275 modeled making the additional hook 272 'associated with the first end 270a of the central portion 27a;

- a second section 276, consecutive to the first 275, which makes a first side of a 28 of the two fins 28, 29;

- a third section 277 modeled (preferably "U"), consecutive to the second 276, which makes the free end 280 folded from a 28 of the two fins 28, 29;

- a fourth section 278, consecutive to the third 277, which performs a second side of a 28 of the two fins 28, 29;

- a fifth section 279, consecutive to the fourth 278, which performs a first section of the consecutive sections 271 of the central portion 27a;

60

- a sixth section 281 modeled (preferably "U"), consecutive to the fifth 279, which makes a hook 272 located between the first of the consecutive sections 271 of the central portion 27a and a second of the consecutive sections 271 of the central portion 27a;

- a seventh section 282, consecutive to the sixth 281, which performs the second of the consecutive sections 271 of the central portion 27a;

- an eighth section 283 modeled (preferably "U"), consecutive to the seventh 282, which makes a hook 272 located between the second of the consecutive sections 271 of the central portion 27a and a third of the consecutive sections 271 of the central portion 27a;

- a ninth section 284, consecutive to the eighth 283, which performs the third of the consecutive sections 271 of the central portion 27a.

The default folding scheme produces a structure in the wire itself that also consists of:

- a tenth section 285 that makes a first side of another 29 of the fins 28, 29 of the spring hitch 27;

- a tenth section 286 modeled (preferably "U"), consecutive to the tenth 285, which makes the free end 290 folded from another 29 of the two fins 28, 29;

- a twelfth section 287, consecutive to the eleventh 286, which performs a second side of another 29 of the two fins 28, 29 of the spring hitch 27;

- a thirteenth section 288 modeled, consecutive to the twelfth, which makes the additional hook 272 '' associated with the second end 270b of the central portion 27a.

Preferably, the accordion structure of the central portion 27a consists of three consecutive sections 271. In this case, the spring hitch 27 is structured in the simplest and most functional way.

The wire portion that includes the consecutive sections from the tenth 285 to the thirteenth 288 is preferably consecutive to the ninth section 284. In this way, a central portion 27a is obtained with three consecutive sections 271.

In addition to the three consecutive sections 271, the accordion structure of the central portion 27a may include one or more additional pairs of consecutive sections 271.

Between the wire portion that includes the consecutive sections from the tenth 285 to the thirteenth 288 and the ninth section 284, an additional wire portion may be included. In said additional wire portion, the predetermined folding scheme produces a structure consisting of one or more sequence of sections, each of which is consecutive to the other. Each sequence consists of four consecutive sections, of which the first is equal to the sixth section 281, the second is equal to the seventh section 282, the third is equal to the eighth section 283 and the fourth is equal to the ninth section 284 In this way, central portions 27a are obtained with one or more pairs of consecutive sections 271 added to the three consecutive sections 271.

Before cooperating with the horizontal part 3 of the perimeter frame 1, specifically, with the second perimeter element 3, the spring hooks 27 cooperate with a protection element 30, preferably (for reasons of lightness) of expanded material, such as polystyrene , which protects said spring hooks 27 during transport of the components of the wall structure (for example, in one or more boxes).

If the support element 22 of the rail section 21 and the rail section 21 are not made in one piece, but are two separate pieces, said protection element 30 can also act as a support surface and as a spacer during the possible fixing operations of the rail section 21 in the support element 22 thereof, which must be performed before coupling the guiding means 12 in the horizontal part 3 of the perimeter frame 1, specifically, in particular, in the second element perimeter 3.

Once the components of the wall structure have been removed from their packaging, the protection element 30 is disengaged from the spring hooks 27. Specifically, specifically, the disengagement is carried out by sliding the protection element 30 until it is removed from the fins 28 and 29 of the spring hitch 27. The assembly of the guiding means 12 is placed in correspondence with the horizontal part 3 of the perimeter frame 1, specifically, in particular, in correspondence with the second perimeter element 3. Next, the guiding means 12 are coupled to the latter horizontal part 3, forcing the spring hooks 27 on it. Specifically, when the horizontal part 3 includes (or is) the second perimeter element 3, the guiding means 12 are coupled in the second perimeter element 3, forcing the spring hooks 27 on the one such that its fins 28 and 29 bent inwards, grasp the second perimeter element 3 itself (figure 4). Then, the guide means 12 may be fixed definitively on the second perimeter element 3 by means of screws, using a suitable and known tool.

Advantageously, the rail section 21 or the relative support element 22, or both, or in any case its

set (specifically when they are made of a single piece, as in the figures), includes or includes, at least one of its opposite free ends, a metric scale 39 that allows to reduce the length of the guiding means 12 according to the needs ( for example, using a suitable and known cutting tool). Thanks to this feature, starting with a single rail section 21 (and / or the corresponding support element 22 and / or its assembly), it is possible to obtain a plurality of guiding means 12 of different lengths, so that they can be used in 16 doors of different widths and / or openings of different lengths in the walls where the wall structure is to be integrated.

Specifically, in the case of a sliding door 16, the elongated construction elements 21, 10, 10A, 11, 11A, in addition to including the first group of elongated construction elements 21 defining the guiding means 12, include a second group of said elongated construction elements defining rectilinear support means 10, 10A, 11, 11A to support the wall panels 14, 15.

Said rectilinear support means 10, 10A, 11, 11A consist of a first 10, a second 10A, a third 11 and a fourth 11A rectilinear support element, which form two pairs (see, specifically, Figures 3, 4, 5, among others). Specifically, as shown in the figures, a first pair is formed by the first 10 and the second 10A rectilinear support element, while a second pair is formed by the third 11 and the fourth 11A rectilinear support element.

Specifically, as illustrated in Figures 4 and 5, the first 10, the second 10A, the third 11 and the fourth 11A rectilinear support element are capable of delimiting the compartment 41 in which the door 16 is hidden (more specifically, the sliding door 16) when moving along the guiding means 12. The first pair of rectilinear support elements 10, 10A is in an intermediate position between an inlet 410 of the compartment 41 and a bottom 411 of the compartment 41. The second pair of rectilinear support elements 11, 11A is located at the entrance 410 of the compartment 41. Specifically, the third 11 and the fourth 11A rectilinear support element must be placed in a position along the second perimeter element 3, which corresponds to the inlet 410 of the compartment 41, while the first 10 and the second 10A rectilinear support element can be placed in a suitable position along the second perimeter element 3 between the Trada 410 and bottom 411 of compartment 41.

The wall structure also includes, for the first 10, the second 10A, the third 11 and the fourth 11A rectilinear support element, a respective first 100, second 100A, third 110 and fourth 110A terminal element that fits into a first end 101a of the respective rectilinear support element 10, 10A, 11, 11A (see, in particular, Figures 3, 4, 13, 15-17). The first end 101a of said respective rectilinear support element 10, 10A, 11, 11A is located on the opposite side with respect to a second end 101b of said respective rectilinear support element 10, 10A, 11, 11A (Figures 3 and 4 ).

Each terminal element 100, 100A, 110, 110A, in turn, consists of a main body 102 and a head 105 (see, in particular, Figures 13, 15-17). The main body 102 has the first axial coupling means 103. The first axial coupling means 103, by interacting along a direction from the first 101a to the second end 101b of the respective rectilinear support element 10, 10A, 11, 11A with the second axial coupling means 104 provided at the first end 101a of said respective rectilinear support element 10, 10A, 11, 11A, determine the connection of said respective rectilinear support element 10, 10a, 11, 11A with the element terminal 100, 100A, 110, 110A (figures 13, 15-19). The address from the first 101a to the second end 101b of the respective rectilinear support element 10, 10A, 11, 11A is the longitudinal extension direction of the rectilinear support element 10, 10A, 11, 11A itself (Figure 3).

The head 105 consists of one or more engagement portions 106 for engaging with a respective elongated side 120 of the guiding means 12.

Each elongated side 120 of the guide means 12 extends along the longitudinal extension direction of the guide means 12 itself. The longitudinal extension direction of the guide means 12 is the direction along which the door 16 slides, when it slides along the guide means 12 themselves. The guide means 12 have a pair of elongated sides 120, parallel to each other and located on opposite sides of the guide means 12. Next, a respective rectilinear support element 10, 10A, 11, 11A of each pair of rectilinear support elements 10, 10A, 11, 11A is engaged on each elongated side 120 of the pair. Specifically, this hitch uses the hitch portion 106 (or the hitch portions 106) of the head 105, as well as the relative end elements 100, 100A, 110, 110A. The elongated face 123 of the guide means 12, in which the spring hooks 27 are fixed, is preferably interposed between the two opposite sides of the guide means 12 on which the pair of elongated sides 120 is located, which they are parallel to each other (fig. 9). Thanks to the coupling between the guide means 12 and the horizontal part 3 of the perimeter frame 1 (specifically, specifically, the second perimeter element 3), the engagement between the engagement portions 106 of the heads 105 of the terminal elements 100, 100A 110, 110A of the pairs of rectilinear support elements 10, 10A, 11, 11A and the respective elongated sides 120 of the guiding means 12 becomes a hitch between the pairs of rectilinear support elements 10, 10A, 11, 11A and the horizontal part 3 of the perimeter frame 1 (specifically, specifically, the second perimeter element 3).

The connection of a rectilinear support element 10, 10A, 11, 11A with the corresponding terminal element 100, 100A, 110, 110A, by the interaction between the first 103 and the second 104 axial coupling means, allows the support element to be prolonged rectilfneo 10, 10A, 11, 11A which, while the rectilinear support element 10, 10A, 11, 11A remains the same, can have a variable length along the direction from the first 101a to the second 101b end of the support element itself rectilfneo 10, 10A, 11, 11A. This result can be obtained simply by coupling the rectilinear support element 10, 10A, 11, 11A to a corresponding terminal element 100, 100A, 110, 110A of different length. The attached figures 13, 15-17 illustrate various embodiments of the terminal element 100, 100A, 110, 110A, specifically, embodiments corresponding to different lengths. In this way, the wall structure has a degree of modularity that allows to obtain structures adaptable to doors of different height using the same rectilinear support elements 10, 10A, 11, 11A. The longitudinal measurements of the terminal elements 100, 100A, 110, 110A are much smaller than those of the respective rectilinear support elements 10, 10A, 11, 11A and offer a significant saving of storage space; In addition, they are easy to introduce, even as a "group" of terminal elements of different lengths, into the box (or boxes) where the different components of the wall structure are stored.

The wall structure is also quite independent of the specific characteristics of the perimeter elements 2, 3, 4 that define the perimeter frame 1, because the heads 105 of the terminal elements 100, 100A, 110, 110A are associated with the guiding means 12; therefore, it is possible to send a single box containing the rectilinear support elements 10, 10A, 11, 11 A, the corresponding terminal elements 100, 100A, 110, 110A, the components of the guiding means 12, the corresponding means of fixing and little else. The perimeter frame 1 can be carried out in situ according to standard modalities.

The second end 101b of each rectilinear support member 10, 10A, 11, 11A can be operatively associated with an additional portion of the wall structure. As specified below and illustrated by way of example in Figures 1, 2, 4, said additional portion of the wall structure may be an additional horizontal part 5 of the perimeter frame 1. Specifically, specifically, the horizontal part 5 is located on the opposite side of the perimeter frame 1 with respect to the horizontal part 3. The additional horizontal part 5 can be a horizontal surface that helps define the opening in which the door 16 operates. Preferably, the additional horizontal part 5 it is a fourth perimeter element 5 of the plurality of interconnected elongate elements. Specifically, the fourth perimeter element 5 has a cross section in the form of "C" and also consists of an intermediate part 6 whose side edges protrude the fins 7, 8 (said fins, in particular, also form part of the corresponding opposite faces 7 , 8 of the interconnected elongated elements of the perimeter frame 1). Specifically, such as the corresponding - and opposite - second perimeter element 3, the fourth perimeter element 5 can also be used of various lengths and / or fixed in different positions with respect to the first 2 and the fourth perimeter element 4, in order to obtain frames 1 perimeters of different lengths. Given the length of the fourth perimeter element 5, its free end 5A is separated from the second perimeter element 4 by a predetermined distance, preferably equal to the depth of the compartment 41 where the door 16 should be housed. Specifically, said distance may be greater or equal. than the width of the sliding door 16 that is intended to be used. In general, the fourth perimeter element 5 is located at the bottom (specifically, in correspondence with the threshold, as a section of a lower longitudinal element).

The association between the second end 101b of each rectilinear support element 10, 10A, 11, 11A and the additional portion of the wall structure can be obtained directly and / or indirectly, in various ways. In a preferred embodiment of the invention, it is obtained as indicated below. Timely, the wall structure also includes, for the first 10, second 10A, third 11 and fourth 11A rectilinear support element, a respective first 116, second 116A, third 117 and fourth 117A additional terminal element that fits into the second end 101b of the respective rectilinear support element 10, 10A, 11, 11 A. In this regard, see, specifically, Figures 3, 5, 14. Specifically, in Figure 14, although it illustrates the detail of the second pair of elements of rectilinear support 11, 11A that must be located at the entrance 410 of the compartment 41, the respective additional terminal elements are indicated not only by reference numbers 117, 117A characteristic of the additional terminal elements of said pair, but also - between parentheses - by reference numbers 116, 116A typical of the additional terminal elements that must be associated with the second end 101b of the rectilinear support elements 10, 10A of the first p areja, which must be located between the entrance 410 and the bottom 411 of the compartment 41; this serves to indicate that, in the embodiment illustrated in the figures, the additional terminal elements of one of the two pairs of rectilinear support elements may be identical to those of the other pair of rectilinear support elements.

With particular reference to Figure 14, each additional terminal element 116, 116A, 117, 117A, in turn, consists of a coupling part 102 'and a fixing part 105'. The coupling part 102 'is provided with additional first axial coupling means 103'. The first additional axial coupling means 103 ', interacting along the direction from the first 101a to the second end 101b of the respective rectilinear support element 10, 10A, 11, 11A with the additional second axial coupling means 104' provided at the second end 101b of said respective rectilinear support element 10, 10A, 11, 11A, determine the connection of said respective rectilinear support element 10, 10A, 11, 11A with the element

additional terminal 116, 116A, 117, 117A. Said connection is well highlighted and visible, specifically, in Figure 21. The fixing part 105 'is connected with the coupling part 102' (specifically, in a single body with it) and can be hooked in said additional portion of the wall structure, specifically, can be fixed to the latter, to fix the rectilinear support element 10, 10A, 11, 11A, which is connected with the respective hooking part 102 ', to said additional portion of the wall structure. Advantageously, the use of the additional terminal elements 116, 116A, 117, 117A improves the modularity of the system, which allows the production and realization of the rectilinear support elements 10, 10a, 11, 11 A to be maximized. they are not responsible for any connection function (neither direct nor indirect) with the different parts of the perimeter frame 1, since this function is completely transferred to the terminal elements 100, 100a, 110, 110A and the additional terminal elements 116, 116A, 117, 117A.

As illustrated by way of example in Figures 14 and 21, in each pair of mutually facing rectilinear support elements 10, 10A, 11, 11A, the fixing portions 105 'of the pair of respective additional terminal elements 116, 116A, 117, 117A are preferably connected to each other to make a "U" shaped element. In this way, the "U" shaped element defines a kind of separating member, associated with each pair of rectilinear support elements 10, 10A, 11, 11A in order to maintain the desired distance between them, specifically, to the passage of the sliding door 16 between the rectilinear support elements 10, 10A, 11, 11 A. The separating member defined in this way is also useful for maintaining the parallelism between the rectilinear support elements 10, 10A, 11, 11A. The separating member defined in this way can be used to correctly fix the rectilinear support elements 10, 10A, 11, 11A on a floor or on any other horizontal surface, specifically when the horizontal part 5 of the perimeter frame 1 is not provided, or when does not include the fourth perimeter element 5 defined with a cross section in the form of "C". When the perimeter frame 1 consists of a horizontal part 5, which, in turn, includes the fourth perimeter element 5 with a "C" shaped cross-section, the separating member, which is defined by the fixing parts 105 'of the pair of the respective additional terminal elements 116, 116A, 117, 117A connected to each other to make a "U" shaped element, is placed in contact with the central part 6 of the fourth perimeter element 5 and is inserted between the fins 7 and 8 of the fourth perimeter element 5 itself. This determines that corresponding portions of the rectilinear support elements 10, 10A, 11, 11A are also introduced between the fins 7 and 8 of the fourth perimeter element 5. Preferably, a flat side portion of the rectilinear support elements 10, 10A, 11, 11A is in contact with said fins 7 and 8 of the fourth perimeter element 5. These last conditions are schematically illustrated in Figure 4, where the "U" shaped spacer member is schematically represented with broken lines in one of the pairs of elements. of rectilfneos support. The fixing parts 105 'are provided with holes for inserting the corresponding screws to fix them to the ground or to any horizontal part of the perimeter frame 1.

The fixing portions 105 'of a pair of additional terminal elements 116, 116A, 117, 117A, which correspond to a pair of rectilinear support elements 10, 10A, 11, 11A, mutually facing each other, can be made joined together in a single body. However, preferably, as specifically illustrated in Figures 3 and 13, the fixing portions 105 'of a pair of additional terminal elements 116, 116A, 117, 117A, which correspond to a pair of rectilinear support elements 10, 10A , 11, 11 A, mutually facing each other, can be connected to each other in such a way that it is possible to modify the distance between the respective engagement parts 102 'and, consequently, between the respective rectilinear support elements

10, 10A, 11, 11A (specifically, to adapt to walls of different thicknesses). With special reference to Figures 14 and 21, each fixing part 105 'consists of a first flanged portion 160a and a second flanged portion 160b which is located next to the first and which lies in a plane parallel to, but different from, the tilt plane of that. The first flanged portion 160a of a fixing part 105 'is intended to overlap the second flanged portion 160b of the other fixing part 105' with which it must be connected and vice versa. The mutual overlap of the flanged portions 160a, 160b of the two fixing parts 105 'that must be connected together may vary within certain predetermined limits, in order to adjust the distance between the respective engagement parts 102'. In the embodiment illustrated specifically in Figures 14 and 21, the amplitude of superposition can be selected from a plurality of different values. Specifically, seats 161 spaced apart from each other are provided in the second open portion 160b of each fixing part 105 ', in each of which a projection 162 of the first flanged portion 160a of each fixing part 105' can be introduced ( see detail II in figure 21). Specifically, the projection 162 can be made in a tongue 163 of the first flanged portion 160a. In this way, a provisional but firm connection is obtained between the two fixing parts 105 'before finally fixing them to the additional horizontal part of the perimeter frame 1.

In a preferred embodiment of the invention, illustrated in the accompanying figures, in the terminal element 100, 100A, 110, 110A which is hooked on the first end 101a of a respective straight support element 10, 10A, 11, 11 A , the first axial coupling means 103 consist of at least one tooth 103. Correspondingly, at the first end 101a of said respective straight support member 10, 10A, 11, 11A, the corresponding second axial coupling means 104 consist of at least an elongate seat 104, which extends along the direction from the first 101a to the second end 101b of said respective rectifying support element 10, 10A, 11, 11A. The tooth 103 is inserted into the corresponding elongated seat 104; said respective straight support element 10, 10A, 11, 11A is therefore connected to the terminal element 100, 100A, 110, 110A, specifically, at its first end 101a, by means of a plug-type mode ( see, specifically, figure 19).

Preferably (as illustrated concretely in Figures 13, 15-18), the first axial coupling means 103 consist of a plurality of teeth 103 and the second axial coupling means 104 consist of a plurality of elongate seats 104 extending to along the first direction from the first 101a to the second end 101b of said respective straight support member 10, 10A, 11, 11A. Each tooth 103 is inserted into a corresponding elongated seat 104; said respective straight support element 10, 10A, 11, 11A is therefore connected with the terminal element 100, 100A, 110, 110A, in a specific manner, at its first end 101a, by means of a plug-type mode.

Specifically, in the first 100, second 100A, third 110 and fourth 110A terminal element, the minimum one tooth 103 (or the plurality of teeth 103), which is part of the first axial coupling means 103, protrudes with respect to the main body 102 and, preferably, is an integral part of it. In the embodiment shown in Figures 13 and 15 (illustrating terminal elements 100, 100A, 110, 110A with a minimum length along the direction from the first 101a to the second end 101b of the respective support element rectilming 10, 10A, 11, 11A), the teeth 103 (or the tooth 103) substantially form (shape) the main body 102. In the cases shown in figures 16, 17, 18, the main body 102 also also includes of the teeth 103, of an extension along the direction that goes from the first 101a to the second 101b end of the respective straight support element 10, 10A, 11, 11A. Said extension is of a different length in order to adapt the wall structure to doors 16 of different heights, while keeping the straight support elements 10, 10A, 11, 11A unchanged.

Advantageously, the elongated seats 104 of the second axial coupling means 104 extend along the entire length of the respective straight support member 10, 10A, 11, 11A, from the first end 101a to the second end 101b. In this way, straight support elements 10, 10A, 11, 11A can be performed directly as simple sections without the need for specific processing operations at their ends. Secondly, concretely and preferably, the straight support elements 10, 10A, 11, 11A can be made directly as extruded sections. As an alternative, the straight support elements 10, 10A, 11, 11A can also be made directly as sections obtained by folding and modeling a single elongated plate.

In a preferred embodiment of the invention, illustrated concretely in the attached figures 14 and 21, in the additional terminal element 116, 116A, 117, 117A which is engaged in the second end 101b of a respective rectilinear support element 10, 10A , 11, 11A, the first additional axial coupling means 103 'consist of at least one additional tooth 103'. Correspondingly, at the second end 101b of said respective straight support member 10, 10A, 11, 11A, the corresponding additional second axial coupling means 104 'consist of at least one additional elongated seat 104', which extends along the address from the first 101a to the second end 101b of said respective straight support member 10, 10A, 11, 11A. The additional tooth 103 'is inserted into the corresponding additional elongated seat 104' (Figure 21); said respective straight support element 10, 10A, 11, 11A is therefore connected to the additional terminal element 116, 116A, 117, 117A, specifically at its second end 101b, by means of a plug-type mode.

Preferably, the first additional axial coupling means 103 'consists of a plurality of additional teeth 103' and the second additional axial coupling means 104 'consists of a plurality of corresponding additional elongated seats 104' extending along the direction from the first 101a to the second end 101b of said respective straight support member 10, 10A, 11, 11A. Each additional tooth 103 'is inserted into a corresponding additional elongated seat 104' (Figure 21); said respective straight support element 10, 10A, 11, 11A is therefore connected to the additional terminal element 116, 116A, 117, 117A, specifically at its second end 101b, by means of a plug-type mode.

Specifically, in the first 116, second 116A, third 117 and fourth 117A additional terminal element, the minimum an additional tooth 103 '(or the plurality of additional teeth 103'), which is part of the first axial coupling means 103 'additional, protrudes with respect to the engagement part 102' and, preferably, is an integral part thereof. In the attached figures, the case is illustrated in which the additional tooth (or additional teeth) 103 'makes the largest portion of the engagement part 102'. In any case, additional terminal elements 116, 116A, 117, 117A of different lengths can be realized, namely, provided with parts of

hook 102 '(of which the additional tooth 103' or the additional teeth 103 'protrudes of different lengths, to add an additional degree of freedom to the possibility of adapting the wall structure to doors 16 of different heights.

Advantageously, when the elongated seats 104 of the second axial coupling means 104 extend along the entire length of the respective rectilinear support member 10, 10A, 11, 11A, from the first end 101a to the second end 101b, the additional elongated seats 104 'of the second additional axial coupling means 104' coincide with the elongated seats 104 of the second axial coupling means 104. Thus, with a single production phase, it is possible to arrange the rectilinear support elements 10, 10A , 11, 11A (as extruded sections or as sections obtained by folding and modeling a single elongated plate) for the introduction of the teeth 103, 103 'of both types of terminal element, without the need for special processing operations at the ends 101a, 101b .

In general, whatever the terminal element in question, preferably:

- in the terminal element 100, 100A, 110, 110A, 116, 116A, 117, 117A, the corresponding first axial coupling means 103, 103 'consist of at least one tooth 103, 103', preferably a plurality of teeth 103, 103 ';

- at the end 101a, 101b of the respective rectilinear support element 10, 10A, 11, 11A, relative to the terminal element 100, 100A, 110, 110A, 116, 116A, 117, 117A, the corresponding second axial coupling means 104, 104 'consist of an elongated seat 104, 104', preferably a plurality of elongated seats 104, 104 ', which extends (preferably, extends) along a direction from the first 101a to the second 101b end of said respective rectilinear support element 10, 10A, 11, 11A.

Each tooth 103, 103 'is inserted into a corresponding elongated seat 104, 104'; said respective rectilinear support element 10, 10A, 11, 11A is therefore connected to the terminal element 100, 100A, 110, 110A, 116, 116A, 117, 117A by a plug-type mode.

In general, the plug-to-plug connection between a terminal element and the corresponding end of the respective rectilinear support element makes the connection itself very easy and efficient.

Preferably, as illustrated in the figures, there are two types of rectilinear support elements 10, 10A, 11, 11A, according to their position of use. Specifically (and with reference, specifically, to Figures 5, 13 and 15), each rectilinear support element 10, 10A, 11, 11A extends along the direction from its first 101a to its second end 101b with a cross section consisting of a central portion 43 with an inner side 44 and an outer side 45. The wall panels 14, 15 come into contact with the outer sides 45. Elongated seats 104 and additional elongated seats 104 'extend between the inner side 44 and the outer

45. Preferably, in the pair of rectilinear support elements 10, 10A, 11, 11A to be located at the entrance 410 of the housing compartment 41 of the door 16, the central portion 43 of the cross section of the rectilinear support elements 11, 11A extends, on the side that must be oriented towards the outside of the compartment 41, in a support and reference structure 46 for the possible finishing of the own entrance 410 of the compartment 41. As it extends along the entire corresponding element of rectilinear support 11, 11A, said support and reference structure 46 results in a corresponding modeled support and reference nerve

46. As shown, specifically, in Figures 16, 17 and 18, when terminal elements 100 are used,

100A, 110, 110A of a length greater than the standard, a part of the extension of the main body 102 that is between the first axial coupling means 103 (specifically, preferably, tooth 103 or teeth 103) and the corresponding head 105, extends below gufa means 12, creating a

space between the straight support elements 11, 11A of the couple located at the entrance 410 of the

compartment 41 and the gufa means 12 itself, where the wall structure would not be provided with any

support and reference structure for the possible finishing of the entrance 410 of the compartment 41.

Advantageously, in this case the wall structure consists of segments 460 of additional profiled element having the same cross section as the support and reference structure 46 and, therefore, the same cross section as the corresponding support and reference nerve 46. Said segments 460 can be introduced by sliding in a guide rib 461 present in the extension of the main body 102 of the terminal elements 100, 100A, 110, 110A (Figure 18), thus completing the support and reference nerve 46 of the elements of rectilfneos support 11, 11A of the couple that is located at the entrance 410 of the compartment 41.

As already stated, the head 105 of each terminal element 100, 100A, 110, 110A consists of one or more engagement portions 106 to engage with a respective elongated side 120 of the guiding means 12. In a preferred embodiment of the invention shown in the figures, the hooking of the head 105 with the respective elongated side 120 of the guiding means 12 is carried out by means of the corresponding one or more hook portions 106, as indicated below. With reference, in particular, to Figures 13, 15, 19, 21, mutual interference means 107 are provided in the engagement portions 106 and on the respective elongated side 120 of the guiding means 12. Said mutual interference means 107, after the hook of the

hook portions 106 on the respective elongated side 120 of the guiding means 12, slide the terminal element 100, 100A, 110, 110A and the respective rectilinear support element connected with the 10, 10A, 11, 11A into the means by sliding guide 12 before being permanently fixed and, at the same time, prevent at least both a movement of the terminal element 100, 100A, 110, 110A with the respective rectilinear support element connected to 10, 10A, 11, 11A along of the direction from the first 101a to the second 101b end of said rectilinear support element 10, 10A, 11, 11 A, as a rotation of said respective rectilinear support element 10, 10A, 11, 11A around its second end 101b.

In this way, by causing the terminal element 100, 100A, 110, 110A to slide along the respective elongated side 120 of the guiding means 12, the position of the pairs of rectilinear support elements 10, 10A can be changed, 11, 11A along the guiding means 12, before definitively fixing their position along them. Thus, it is possible to change the dimensions of the compartment 41 where doors 16 of different widths are accommodated, easily and without the need for any additional components.

By preventing at least the movements of the terminal element 100, 100A, 110, 110A along the direction from the first 101a to the second 101b end of the rectilinear support element 10, as well as the rotational movements around the second end 101b once the engagement portions 106 are engaged on the elongated side 120 so that the action of the mutual interference means 107 is activated, the operation of the sliding operation is possible without separating the rectilinear support element 10, 10A , 11, 11a of the elongated side 120 of the guiding means 12.

Figure 22 shows the different parts of the elements in which the mutual interference means 107 are obtained. In Figure 19, the coupling obtained is shown and the action of the mutual interference means 107 can be seen.

When also the second end 101b of each rectilinear support element 10, 10A, 11, 11A is operatively associated with the additional horizontal portion of the wall structure (specifically, the additional horizontal part 5 of the perimeter frame 1; specifically, even more specifically, to the fourth perimeter element 5), so that it can slide along said additional horizontal portion of the wall structure (specifically, for example, with the fixing parts 105 'supported by the portion additional to the wall structure, but not fixed in the latter), the link produced by the reciprocal action of the mutual interference means 107 keeps each rectilinear support element 10, 10A, 11, 11A in position, and at the same time It allows its sliding movement along the guiding means 12, without the need to hold it manually or keep it in contact with the gufa means 12.

As already stated, in a preferred embodiment, the fixing parts 105 'of the additional terminal elements 116, 116A, 117, 117A corresponding to each pair of rectilinear support elements 10, 10A, 11, 11A, mutually facing each other , are connected to each other to make a "U" shaped element that, in this way, defines a kind of separating member associated with each pair of rectilinear support elements 10, 10A, 11, 11 A. In this case, each a pair of rectilinear support elements 10, 10A, 11, 11A can be in equilibrium, supported by the "U" shaped element formed by the additional terminal elements 116, 116A, 117, 117A, even before fixing the parts of fixing 105 'in the additional portion of the wall structure; thanks to the action of the mutual interference means 107, the engagement of the heads 105 of the terminal elements 100, 100A, 110, 110A on the respective elongated sides 120 of the guide means 12 does not allow the rectilinear support elements 10 , 10A, 11, 11A are placed in a plane perpendicular to the direction in which the guide means 12 extend. However, sliding movement of the pair of rectilinear support elements 10, 10A, 11, 11A is allowed a along the elongated sides 120 of the guiding means 12, substantially stable and without the need for other aids.

With specific reference to FIGS. 13, 15, 19, 22, the mutual interference means 107 consist of a first contact portion 108a of the engagement portions 106, in a distal position with respect to the main body 102 and to a longitudinal axis 121 of guide means 12 (indicated by dashed lines in figures 6 and 13 and by a point within a circle in figures 7, 19 and 22, where it is perpendicular to the plane of the sheet). Said first contact portion 108a is in contact with a corresponding first contact surface 122a of the respective elongate side 120, in a distal position with respect to the longitudinal axis 121 of the guiding means 12. The mutual interference means 107 also consists of a second contact portion 108b of the engagement portions 106, in proximal position with respect to the main body 102 and longitudinal axis 121 of the guiding means 12. Said second contact portion 108b is in contact with a corresponding second contact surface 122b of the respective elongate side 120, in proximal position with respect to the longitudinal axis 121 of the guiding means 12. Specifically, said first 108a and second 108b contact portions are located, relative to each other, at the ends of a diagonal line which is transverse to the direction of extension of the guide means 12 (specifically, preferably, lying in a perpendicular plane to the extension address of the guiding means 12). The longitudinal axis 121 of the guide means 12 is parallel to the direction of extension of the guide means 12.

The second contact portion 108b extends in a portion 109 having a cross section in the form of

"C" in a plane perpendicular to the longitudinal axis 121 of the guide means 12. A corresponding part of the respective elongated side 120 of the guide means 12 is inserted into said part in the form of "C" 109.

Timely, generally, the mutual interference means 107 consist of an elastically deformable part 111 of the head 105, which is provided with one or more projections 112 which are elastically inserted into corresponding seats 113 of the respective elongate side 120. Advantageously, as illustrated only by way of example and not limitation in the attached figures, which show a preferred embodiment of the invention, the elastically deformable part 111 of the head 105 is located on the first contact portion 108a of the portions of coupling 106. Preferably, the elastically deformable part 111 of the head 105 coincides with the first contact portion 108a of the coupling portions 106.

As shown in the figures, the head 105 may consist of a plurality of portions 114 separated from each other along the respective elongated side 120 of the guiding means 12.

Advantageously, the wall structure according to the invention also consists of a lateral extension 115 of the head 105 introduced as a spacer between the head 105 and the respective elongated side 120 of the guiding means 12 (Figures 20, 23-25). The lateral extension 115 is provided with an additional engagement portion 106 'that engages on the respective elongated side 120 of the guiding means 12 instead of the engagement portions 106 of the head

105 and fulfills the same purpose. Specifically, advantageously, the additional hitch portion 106 'consists of parts that are identical to the hitch portions 106 of the head 105.

Thus, by providing the wall structure with a lateral extension 115 for the head 105 of each terminal element 100, 100A, 110, 110A, it is possible to adapt the wall structure to walls of different thicknesses. Specifically, by changing the thickness of the lateral extension 115, structures that adapt to any desired thickness can be obtained, without intervening in the main components of the structure itself. Specifically, as shown in the figures, the lateral extension 115 can be coupled to the engagement portions

106 of the head 105 by its side 118 opposite to the side where the additional hook portions 106 'are located (specifically, by a movement such as that indicated by the arrow in Figures 24 and 25). Preferably, the extension 115 of the head 105 is provided with snap hook means 119 located on the side 118 opposite the side where the additional hook portions 106 'meet and interact with corresponding snap hook means 119' located at head 105. Specifically (figures 20 and 24), the snap-on means 119 consist of two elastically deformable lips 164, provided with hook teeth 165. The lips 164 can be elastically inserted into through-seat seats 166 obtained in the head 105, with sufficient depth to allow the ends of the lips 164 to exit the through seats 166 and expand, causing the engagement teeth 165 to engage in contact with the retaining surfaces 167 obtained in the head 105 (figure twenty).

With concrete reference to Figures 3, 4, 11, 26, 27, the wall structure according to the invention also consists of at least two finished crossbars 24, 25 of predetermined length, which are laterally associated with guiding means 12 in an area in which said guide means 12 are visible to a user, to close and protect the guide means 12 themselves and as a finish. Specifically, in the wall structure with sliding door 16 and housing 41 for housing of the door 16, the finishing crossings 24, 25 are associated with the guiding means outside the compartment 41. The finishing crossings 24, 25 are they associate to the elongated sides 120 of the gufa means 12. Specifically, the gufa crossings 24, 25 are located outside the compartment 41, in a immediately consecutive position to the rectilinear support elements 11, 11A of the pair defining the inlet 410 of the compartment 41. Being associated with the elongated sides 120 of the guiding means 12, the finishing crosspieces 24, 25 are placed in a immediately consecutive position to the terminal elements 110, 110A associated with the first end 101a of the elements of rectilinear support 11, 11A of the couple defining the inlet 410 of the compartment 41. The finishing crosspieces 24, 25 may be of sufficient length to cover the entire visible portion of the opening d It is designed to be closed by door 16 (or doors 16, in the case of a double door, as in Figure 2). Alternatively, the length of said visible portion may be covered with a plurality of finishing cross members 24 on one side of the guide means 12 and the corresponding finishing cross members 25 on the other side of the guide means 12. Timely, the cross members finishing 24, 25 have a cross section in the form of "L", with a long side 240, 250 and a short side 241, 251. Both the short side 240, 250 and the long side 241, 251 have coupling means for hooking on the elongated sides 120 of the guiding means 12. When the finishing crosspieces 24, 25 have the short side 240, 250 associated with the elongated sides 120 (figure 11; figure 26, detail "(i)"; figure 27 (a)), they are in a first position of minimum width. When the finishing crosspieces 24, 25 have the long side 241, 251 associated with the elongated sides 120 (Figure 26, detail "(ii)"; Figure 27 (b)), they are in a second position of maximum width. In this way, the same finishing elements 24, 25 can be adapted to wall structures of different thicknesses. Specifically, advantageously: the first minimum width position can correspond to the width of the heads 105 of the terminal elements 100, 100A, 110, 110A; the second maximum width position may correspond to the width of the heads 105 of the terminal elements 100, 100A, 110, 110A increased by the width of the lateral extensions 115. The first minimum width position may correspond to a first increased position of the spring hooks 27; the second maximum width position may correspond to a second enlarged position of the spring hooks 27. In the embodiment shown in the figures, the free end of the short side 240, 250 is provided with a corresponding projection 242, 252 which, to what

along the longitudinal extension of the finishing crosspiece 24, 25, it becomes a corresponding rib 242, 252 which is introduced into a first longitudinal seat 124 of a corresponding elongated side 120 of the guiding means 12, and extends along of the guide means 12 themselves. The introduction can be carried out under pressure, along a direction that is transverse with respect to the longitudinal axis of extension of the guide means 12. The introduction can be carried out by sliding along the length of the direction of the extension axis of the guide means 12, starting at one end of said guide means 12. When the rib 242, 252 of the short side 240, 250 is introduced into the first longitudinal seat 124, the finishing cross member 24, 25 is in the first position of minimum width. In the embodiment shown in the figures, the free end of the long side 241, 251 is provided with a corresponding projection 243, 253 which, along the longitudinal extension of the finishing traverse 24, 25, becomes a corresponding rib 243, 253 which is introduced into an additional longitudinal seat of the corresponding elongated side 120 of the guiding means 12, and extends along the guiding means 12 itself. The introduction can be carried out under pressure, along a direction that is transverse with respect to the longitudinal axis of extension of the guide means 12. The introduction can be carried out by sliding, along the direction of the extension axis of the guide means 12, starting at one end of said guide means 12. When the rib 243, 253 of the long side 241, 251 is introduced into the additional longitudinal seat, the finishing cross member 24, 25 is in the second position of maximum width. Preferably, the additional longitudinal seat coincides with the first elongated seat 124. Advantageously, each elongated side 120 of the guiding means 12 is provided with a second longitudinal seat 125, parallel to the first longitudinal seat 124 and positioned with respect to that in such a way. that when the finishing cross member 24, 25 is in the first minimum width position, the introduction of the rib 242, 252 of the short side 240, 250 into the first longitudinal seat 124 of the corresponding elongated side 120 coincides with the introduction of the rib 243, 253 of the long side 241, 251 in the second longitudinal seat 125 of the corresponding elongated side 120.
