Description

FIELD OF TECHNOLOGY

It is an object of the present invention to provide an easily transportable and easily assembled wall structure with a sliding door or for a sliding door.

Some parts that are indicated in the following description can also be used separately as such with different types of wall structures, for example, with sliding hinged doors or with folding doors; otherwise, in general, these parts can be separately used as such for connecting the guide rails (or, generally speaking, the guide means of sliding) with the horizontal parts of the peripheral frames of the wall structures for the doors (in particular, with a jumper of the opening where the door should be located )

BACKGROUND OF THE INVENTION

Generally speaking, various situations are known in which a door opens or closes by a sliding movement. In particular, you can find three types of doors that correspond to these situations: sliding doors, sliding swing doors, folding doors.

A sliding door slides between two extreme positions, a closed position and an open position, while maintaining its own plane constant (or parallel to itself) and supported by a sliding rail, as a result of which at least two carriages that are attached to the horizontal edge of the door engage .

The sliding hinged door slides along the guide during the opening / closing movement, and at the same time, its own plane rotates around a pivot axis, which, generally speaking, is supported by the carriage holding the door on the guide.

A folding door consists of several sections (or segments) pivotally fastened to each other at their vertical edges with the formation of several rotary axes. In the transition from a closed configuration to an open configuration, when the folding door is folded into an accordion-like shape on the side of the wall structure, various sections of the folding door are rotated around said rotary axes. Thus, each individual section undergoes a sliding-pivoting movement, similar to the movement of one sliding swing door; one of the two rotary axes of each section is supported by a corresponding carriage, which, in turn, is engaged with a guide supporting the door.

All these situations are characterized by the problem of connecting the slide rails (or sliding guide means) with the horizontal parts of the peripheral frames of the wall structures for doors, in particular, with the jumper of the opening where the door should be placed.

Particularly with sliding doors (and, above all, when the door, when it is in the open position, must be hidden inside the corresponding case), the problem lies in constructing the frame structure, which is necessary to maintain and / or accommodate the door itself.

Various wall constructions with sliding doors are known. One of them, for example, contains a preformed parallelepiped-shaped element for communication with peripheral elements of the wall structure and having a seat for receiving the sliding door during its movement. Wall panels of the structure (for example, of drywall) are attached to the indicated element using screws or similar elements. The areas into which these screws are inserted into the wall panels are then coated accordingly.

This known construction has various disadvantages, such as the large dimensions of the preformed element (at least equal to the size of the sliding door), leading to obvious problems in terms of transportation, weight and handling during assembly of the wall structure. Due to the size of the preformed element, the method of attaching it to the wall panels and the difficulties of transportation, it takes several people (at least two) to assemble the wall structure, which negatively affects the cost of assembly. In addition, this known design allows to obtain wall structures only in predetermined sizes, each of which requires a corresponding pre-formed element of appropriate sizes. This means that the supplier of such structures must necessarily stock items of all possible sizes, which leads to a very high cost of storage.

And finally, due to the size limit of known wall structures, it is not possible to form structures of special non-standard sizes.

Another known structure is applicable, in particular, when the frame of the building into which the structure is to be inserted consists mainly of wooden beams. In this case, after choosing the position in which the structure with the sliding door will be located, the elements (also made of wood) are attached to the specified beam to obtain a compartment for the specified door, and then wall panels made of drywall are fixed to them. This design also has various disadvantages, including the fact that it can only be used for wall structures of certain sizes, and only in buildings that have a frame of wooden beams. In addition, several people are required to assemble a design with a sliding door, which implies significant assembly costs.

US Pat. No. 4,561,210 illustrates a wall structure for sliding doors, which can also be used when the walls are formed by pairs of parallel panels facing each other, in particular prefabricated and / or drywall panels. It contains a peripheral frame, where a pair of vertical struts connects the upper longitudinal element having a cross section in the form of an inverted letter “U”, with the lower longitudinal element having a cross section in the form of an inverted letter “U”, and is interrupted in accordance with the opening in the wall, which must be closed by a sliding door. To receive a sliding door, when it moves in the open position, the box is made by attaching several vertical elements facing each other to the upper and lower longitudinal elements (and then covering the same elements with plasterboard or similar panels). The upper end of each vertical element is inserted into the hole of the corresponding shape of a given size, which is made on the horizontal surface of the upper element. The lower end of each vertical element is given the corresponding shape of the structure with two shoulders in order to interact “in a forked way” with one of the vertical flanges of the lower longitudinal element and be attached to it with screws. The sliding rail, with which the supporting wheels (or carriages) of the sliding doors are engaged, is screwed to the end of two additional vertical posts that are attached to the lower longitudinal element and fixed with screws on the upper longitudinal element. Even if the problem of the overall dimensions of the preformed element is eliminated, this solution has several drawbacks, including the possibility of using certain sizes only in wall structures. In particular, the vertical elements must be located in positions that are strictly defined by the formed holes into which the upper ends of the vertical elements must be inserted, and these holes must be preformed in the central surface of the upper longitudinal element in the manufacture of this element. In addition, for attaching the lower ends of the vertical elements to the lower longitudinal element, complex and specific processing of the lower end itself is required. In addition, support for the slide rail is obtained in a laborious manner.

European patent No. 0751275 B1 discloses a wall structure of the type shown in US patent No. 4561210, which is simplified and improved to address some of the disadvantages of the latter. In particular, the box for a sliding door is limited by pairs of vertical elements, the lower and upper ends of which are identical to each other and have a shape that allows them to engage in a “forked way” with the vertical flanges of the lower longitudinal element: thus, during the assembly, the vertical elements are symmetrically relative to the permutation their upper part and their lower part.

The wall structure further comprises a set of guide means, which are made up during the assembly process by cutting them to the required size. Said set of guide means comprises a support member and a sliding rail. The latter is attached to the surface of the support element. On the front side of the support element opposite to the one where the rail is attached, several omega-shaped spring-shaped spring clips are also attached, in which the opposite protrusions are bent towards the inside of the support element. The connection of the band-shaped spring clips with the upper longitudinal element provides a stable connection between the latter and the rail, before finally fixing the position of the rail using the appropriate screws, which simplifies the step of assembling the rail.

The upper end of each vertical element does not reach the upper longitudinal element, but is adjacent to the corresponding side surface of the rail support element. Due to the use of a “fork” clutch between the lower end of the vertical element and the vertical flange of the lower longitudinal element (while manually holding the upper end abutting against the side surface of the rail support element) - and before fastening all this with screws, you can make vertical elements freely sliding along lower longitudinal element, thus changing, as desired, the size of the box, which corresponds to the width of the door. Once the correct arrangement of the vertical elements has been individualized, their stable position can be ensured by attaching their ends to the rail support element and to the vertical flanges of the lower longitudinal element, respectively, using the corresponding fixing screws. Despite the fact that the assembly of the wall structure is simplified and certain freedom is allowed in the application of the same system for sliding doors of different widths (in particular, due to the possibility of ensuring free sliding of vertical elements along the lower longitudinal element before fixing them), this solution also does not free from flaws. In particular, the wall structure is not directly applicable to sliding doors of various heights: processing the ends of vertical elements, which is necessary for their engagement with the lower longitudinal element, actually makes it impossible to apply the same vertical elements to doors of different heights, which makes production necessary and storage of vertical elements of various lengths. Moreover, when moving vertical elements along the lower longitudinal element before their final attachment, which sets their correct position, the upper end of the vertical elements is supported simply by abutting against the supporting element of the rail, which allows vibrations of the vertical element itself away from the supporting element of the rail, which are all the more annoying the higher the door.

Another disadvantage is that fitting the structure to walls of different thicknesses, in particular on peripheral frames having horizontal longitudinal elements of different widths, is difficult, if not impossible. In addition, strip-shaped spring clips located on the rail support member cannot be easily mounted on longitudinal members having different widths (where the term width refers to the wall thickness where the door should be installed). In fact, by using the elasticity of the opposite protrusions of the omega-shaped strip-shaped spring, one can only partially cope with small variations in the width of the longitudinal element (in particular, with small changes in the thickness of the corresponding wall).

The problem of installing the connecting system of the guide system on the walls and / or peripheral frames of various thicknesses exists for all wall structures, not only for sliding doors, but also for sliding swing doors or for folding doors, and, in general, for all those wall structures that suggest the use of a guide system that allows sliding movement of the door and which must be attached to the horizontal part of the peripheral frame. In general, in all these cases, the use of a rail support member having strip-shaped spring clips of the type described above does not completely solve the problem. In fact, in the band-shaped spring clips located on the rail support element, they cannot be easily adapted to the horizontal parts of the peripheral frame having different widths (width means the corresponding thickness of the wall where the door should be installed). In fact, the elasticity of the opposite protrusions of the omega-shaped strip-shaped spring helps to only partially cope with small variations in the width of the indicated horizontal part (in particular, with small variations in the thickness of the corresponding wall).

SUMMARY OF THE INVENTION

The aim of the present invention is to provide an easily transportable and easily assembled wall structure with or for sliding doors, which eliminates the aforementioned disadvantages. The specific objective of the present invention is to provide a wall structure, the elements of which are easily transported, have small dimensions, due to which they can be packaged in a box, and have significant versatility, which allows to obtain wall structures of various sizes, essentially from the same basic elements without special additional work operations.

Another objective of the present invention is to provide a wall structure that can be easily installed in walls of various thicknesses, even on the basis of the same basic elements.

These and other objectives, which will become more apparent in the following description, will be achieved, in accordance with the present invention, in an improved wall structure with a sliding door or with a sliding hinged door or for such doors having the structural and functional features described in the independent claims inventions, with additional embodiments described in the respective dependent claims.

MODES FOR CARRYING OUT THE INVENTION

As shown in the drawings, a wall structure with a door or for a door configured for sliding movement, in particular a sliding door or a sliding hinged door or a folding door (the latter is essentially equivalent to a group of sliding hinged doors for the purposes of the present description, as already mentioned in the introduction parts of the present description) generally comprises a first set of elongated structural elements 21 intended for functional connection with the peripheral frame 1 to form a guide it means 12 (in particular, at least the rail section 21 for connecting with the horizontal portion 3, a peripheral frame 1) for door sliding along its direction of motion.

In General, the frame 1 is of the type in which there are several interconnected elongated elements. Wall panels 14, 15 are designed for fastening to opposite surfaces 7, 8 of these interconnected elongated elements. In particular, said wall panels may be gypsum boards or panels made of the same material. A compartment 41 is made between the wall panels 14, 15. In the particular case of a sliding door, the door 16 can slide into the compartment 41 to be contained therein.

The elongated elements connected to each other and bounding the frame 1 comprise: a first peripheral element 2, a second peripheral element 3, a third peripheral element 4. Said first 2, second 3 and third 4 peripheral elements are fastened together in a conventional manner. Each of these latter has a “C” -shaped cross section and contains an intermediate part 6 from which flanges 7 and 8 protrude from its lateral edges (in particular, in a non-limiting embodiment, the respective opposing surfaces 7, 8 of the elongated peripheral frame elements connected to each other 1 obtained on these flanges).

The span of the structure can be changed in a known manner using the second peripheral element 3 of a different length and / or by fixing it in a different position relative to the first 2 and third 4 peripheral element. In General, the second peripheral element 3 is located on top (namely: in the jumper position, as the upper longitudinal element). In addition, the span of the structure can be changed in a known manner, using the first 2 and second 4 peripheral elements of different lengths.

In particular, an easily transportable and easily assembled wall structure with or for sliding doors, contains elongated structural elements 21, 10, 10A, 11, 11A, made with the possibility of functional connection with the peripheral frame 1.

The elongated structural elements 21, 10, 10A, 11, 11A are arranged to be located in close proximity to the peripheral elements 2, 3, 4.

The first set of elongated structural elements 21 limits the guide means 12 for guiding the door 16 during its sliding movement. The door 16 slides along the guide means 12 by means of wheels 17 attached to the door using conventional fasteners 18. At least a known brake 20 is arranged to counteract the free movement of the wheels along the guide means 12.

In one embodiment, suitable for several types of doors 16 (and not only for a sliding door, but also for a sliding hinged door and a folding door and, in general, to all cases in which a door needs a means to facilitate its sliding along horizontal direction), the guiding means 12 comprises at least a rail section 21 for connecting to the horizontal part 3 (in particular, to the second peripheral element 3) of the peripheral frame 1. This embodiment is suitable for several types of doors 16, may even contain only the first set of elongated structural elements (indicated by the number 21 above), which limits the guide means 12. In the embodiment shown in the drawings, the rail section 21 is limited to the corresponding support element 22. The support element 22 of the rail section 21 can be made of wood or other material (for example, plastic made under wood). Preferably, in the embodiment shown in the drawings (see, in particular, Figs. 6 and 7, among others), the supporting member 22 of the rail section 21 is integrally formed with the corresponding rail section 21. In particular, they can be manufactured in as one extruded profile.

Several spring clips 27 are also connected to the guiding means 12, which are adapted to interact with the horizontal part 3 of the peripheral frame 1 to connect the guiding means 12 with the horizontal part 3 of the peripheral frame 1 even before the final fixing of the guiding means 12 to the horizontal part 3 of the peripheral frame 1 s using screws or the like. In particular, in particular, when the peripheral frame 1 has elongated elements connected together, comprising the first 2, second 3 and third 4 peripheral elements, the horizontal part 3 of the peripheral frame 1 is the second peripheral element 3. Preferably, the second peripheral element 3 is an upper longitudinal frame element 1. In this case, therefore, several spring clips 27 support the guiding means 12 to the second peripheral element 3 even before the final fixing of the means 12 to the periphery iynomu element 3. As already mentioned, the final fastening can be performed by means of screws or the like.

The strip-shaped spring clips 27 can be conventional “omega” -shaped clips that include a central portion that can be attached to the guiding means 12 and two opposing protrusions that protrude from the indicated central portion far from the guiding means 12 and are curved toward the inner parts of the omega-shaped structure, in particular, above the central part. Preferably, the spring clips 27 have an innovative shape, more adapted to walls of various thicknesses (in particular, to the horizontal parts 3 of the peripheral frame 1 having different thicknesses). The following description of the spring clips 27 will be made with specific reference to FIG. 8-10. The spring clips 27 comprise a central part 27a connected to the guide means 12 on the elongated side 123 of the guide means 12, which is configured to face the horizontal part 3 of the peripheral frame 1. In particular, when the guide means 12 comprises at least one rail section 21 and the support member 22 of the rail section 21 (which is preferably integrally formed with the rail section 21 itself, as described above), the central portion 27a of the clamp 27 is connected to the surface of the support member and 22 of the rail section 21. In particular and specifically, the central portion 27a of the clamp 27 is located on the support member 22, on the other side of the latter, with respect to the corresponding rail section 21. The spring clip 27 also contains at least two protrusions 28, 29 located on opposite sides of the central part 27a with respect to the X axis of the clamp 27. The X axis of the clamp 27 coincides with the longitudinal axis of the guide means 12 when the clamp 27 is mounted on the guide means 12. Between its first end 270a, in accordance with which in 28 of the two protrusions 28, 29, and its second end 270b, in accordance with which the other 29 of the two protrusions 28, 29 is located, the central part 27a extends along the X axis of the spring clip 27 through several sections 271 that are consecutive with respect to each other to a friend, and transversely to the X axis of the spring clip 27, following a zigzag path along the same X axis of the spring clip 27. The accordion-like structure is formed by several successive sections 271 that are compressible or extendable along the X axis of the clip 27. Compressing the gar of the midge-shaped structure along the X axis of the clamp 27 determines the corresponding extension of this accordion-shaped structure perpendicular to the same X axis, after which the protrusions 28, 29 of the spring clip 27 are removed from each other perpendicular to the X-axis of the clip 27. The extension of the accordion-shaped structure along the X axis of the clip 27 determines the corresponding the shortening of this accordion-like structure is perpendicular to the same X axis, after which the protrusions 28, 29 of the spring clip 27 approach each other perpendicular to the X axis of the clip 27 itself. Zoom, the use of accordion-like construction allows the central portion 27a to fit the clips 27 to the horizontal peripheral portion 3 of the frame 1, having a different width corresponding to the different thickness of the walls.

The hooks 272 are connected to the common ends of successive sections 271 and are adapted to engage the guide means 12. In particular, the hooks 272 are adapted to engage with corresponding seats 273 provided on the elongated surface 123 of the guide means 12. Preferably, the seats 273 for the hooks 272 made in the form of longitudinal grooves on an elongated surface 123. When the seats 273 for hooks 272 are made in the form of longitudinal grooves of the guiding means 12, they can be obtained those with the guiding means 12 by performing one extrusion step, in particular together with the rail section 21 and the corresponding supporting element 22. A corresponding, additional hook 272 ', which is adapted to engage with the guiding means 12, is connected with the first end 270a of the central part 27a spring clips 27. A corresponding additional hook 272 ″, which is adapted to engage with the guide means 12, is connected to the second end 270b of the central portion 27a of the spring clips 27. Preferably, The individual hooks 272 ', 272' 'of the central portion 27a of the spring clips 27 engage with the same seats 273 designed to engage the hooks 272. In order to use the same guiding means 12 (in particular the same rail section 21) on the walls of various thicknesses, the elongated surface 123 of the guide means 12 may have different seats 273, 273 'for hooks 272, 272', 272 '', which correspond to different wall widths and / or different widths of the horizontal part 3 of the peripheral frame 1 .

The free end 280, 290 of the protrusions 28 and 29 of the spring clip 27 located distally from the central part 27a is itself bent in the direction of the X axis of the spring clip 27. Thus, if you look at the spring clip 27 at least along its X axis, then the “omega" -like spring clip 27 design itself is reproduced, which is used to connect to the horizontal portion 3 (in particular, specifically to the second peripheral element 3) of the peripheral frame 1. As shown, in particular, in FIG. 10, the spring clip 27 preferably comprises a metal wire of a predetermined length that is folded in accordance with a predetermined pattern to form at least both the accordion-like structure of the central part and the protrusions 28, 29. Preferably, the predetermined folding pattern also allows the formation of hooks 272. Preferably , a predetermined folding pattern also allows the formation of additional hooks 272 ', 272' '. Metal wire can be made of steel. Preferably, the steel used is a spring steel type. In a preferred embodiment of the present invention, shown in particular in FIG. 10, all elements of the spring clip 27 are obtained from a single metal wire folded in accordance with a predetermined folding pattern. The wire of a given length has a first end 274a, which corresponds to the first end 270a of the Central part 27a, and a second end 274b, which corresponds to the second end 270b of the Central part 27b.

In particular, starting from the first end 274b of a wire of a given length and passing to the second end 274b of a wire of a given length, the predetermined folding pattern forms a structure on the wire itself, which contains:

- profiled first section 275, which is an additional hook 272 'associated with the first end 270a of the Central part 27A;

- the second section 276, located sequentially after the first 275, representing the first side of one 28 of the two protrusions 28, 29;

- profiled (preferably “U” -shaped) third section 277, located sequentially after the second 276 and representing a bent free end 280 of one 28 of the two protrusions 28, 29;

- the fourth section 278, located sequentially after the third section 277, representing the second side of one 28 of the two protrusions 28, 29;

- the fifth section 279, located sequentially after the fourth section 278, which is the first of consecutive sections 271 of the Central part 27A;

- a profiled (preferably “U” -shaped) sixth section 281 located sequentially after the fifth section 279, which is a hook 272 located between the first of the successive sections 271 of the central part 27a and the second one of the consecutive sections 271 of the central part 27a;

- the seventh section 282, located sequentially after the sixth section 281, which is the second of consecutive sections 271 of the Central part 27A;

- a profiled (preferably “U” -shaped) eighth section 283 located sequentially after the seventh section 282, which is a hook 272 located between the second of the successive sections 271 of the central part 27a and the third of the successive sections 271 of the central part 27a;

- the ninth section 284, located sequentially after the eighth section 283, located sequentially after the third of consecutive sections 271 of the Central part 27A.

A predetermined folding scheme forms the design of the wire itself, which additionally contains:

- the tenth section 285, representing the first side of the other 29 of the protrusions 28, 29 of the spring clip 27;

- profiled (preferably "U" -shaped) eleventh section 286, located sequentially after the tenth section 285 and representing a bent free end 290 of another 29 of the protrusions 28, 29;

- the twelfth section 287, located sequentially after the eleventh section 286 and representing the second side of the other 29 of the protrusions 28, 29 of the spring clip 27;

- profiled thirteenth section 288, located sequentially after the twelfth section, which is an additional hook 272 "connected to the second end 270b of the Central part 27A.

Preferably, the accordion-like structure of the central part 27a consists of three consecutive sections 271. In this case, the spring clip 27 is designed in the most simple and functional way.

The part of the wire, which contains successive sections from tenth 285 to thirteenth 288, is preferably arranged sequentially after the ninth section 284. Thus, the central part 27a has three successive sections 271.

In addition to the three consecutive sections 271, the accordion-like structure of the central part 27a may contain one or more additional pairs of consecutive sections 271.

Between the part of the wire, which contains successive sections from the tenth 285 to the thirteenth 288, as well as the ninth section 284, may have an additional part of the wire. On the specified additional part of the wire, a predetermined folding scheme forms a structure containing one or more sequences of sections, each of which is located sequentially after another. Each sequence contains four consecutive sections, of which: the first section is the same with the sixth section 281, the second section is the same with the seventh section 282, the third section is the same with the eighth section 283, the fourth section is the same with the ninth section 284. Thus, the central parts 27a are obtained with one or more pairs of consecutive sections 271 added to three consecutive sections 271.

Before interacting with the horizontal part 3 of the peripheral frame 1, in particular with the second peripheral element 3, the spring clips 27 interact with the protective element 30, preferably (for reasons of lightness) of expandable (in volume) material, such as polystyrene, which protects the spring clips 27 during transportation of wall elements (for example, in one or more boxes).

When the supporting element 22 of the rail section 21 and the rail section 21 are not formed as a whole, but as two separate parts, the protective element 30 can also act as a supporting surface and gasket during subsequent mounting operations of the rail section 21 to its supporting element 22, which must be performed before attaching the guide means 12 to the horizontal part 3 of the peripheral frame 1, namely, in particular, to the second peripheral element 3.

After the wall elements have been removed from the packaging, the protective element 30 is detached from the spring clips 27. In particular, the disconnection occurs by sliding the protective element 30 out of the protrusions 28 and 29 of the spring clip 27. The set of guide means 12 is then placed in accordance with the horizontal part 3 of the peripheral frame 1, namely, in particular, in accordance with the second peripheral element 3. The guiding means 12 are then connected to this last horizontal part 3, inserting around the spring presses 27. In particular, when the horizontal part 3 comprises (or is) a second peripheral element 3, the guiding means 12 are connected to the second peripheral element 3 by inserting spring clips 27 around so that their protrusions 28 and 29 bent inward are gripped on top of the second peripheral element (Fig. 4). The guide means 12 can then be finally fixed to the second peripheral element 3 with screws using a suitable known tool.

Preferably, the rail section 21 or its corresponding support element 22, or both, or their assembly in any case (in particular, when they are made as a whole, as in the drawings) contains or contains on at least one of them opposite free ends metric scale 39, which allows to reduce the length of the guide means 12 in accordance with the requirements (for example, using a suitable known cutting tool). By virtue of this feature, starting from one rail section 21 (and / or the corresponding support element 22 and / or their assembly), several guide means 12 having different lengths can be obtained so that they can be used on doors 16 of different widths and / or holes of various lengths in the wall into which the wall structure is to be integrated.

In particular, in the case of the sliding door 16, the elongated structural elements 21, 10, 10A, 11, 11A, in addition to the fact that they contain a first set of elongated structural elements 21 forming the guiding means 12, contain a second set of these elongated structural elements, bounding the straight support means 10. 10A, 11, 11A to support the wall panels 14, 15.

The straight support means 10, 10A, 11, 11A comprise the first 10, second 10A, third 11 and fourth 11A straight support elements forming two pairs (see, in particular, Figs. 3, 4, 5, among others). In particular, as shown in the drawings, the first pair is formed by the first 10 and second 10A support elements, while the second pair is formed by the third 11 and fourth 11A rectilinear support elements.

In particular, as shown in FIG. 4 and 5, the first 10, the second 10A, the third 11 and the fourth 11A, the straight support elements can delimit the chamber 41 into which the door 16 (in particular, the sliding door 16) disappears when moving along the guide element 12. The first pair of straight support elements 10, 10A is in an intermediate position between the entrance 410 to the compartment 41 and the lower part 411 of the compartment 41. A second pair of rectilinear support elements 11, 11A is located at the entrance 410 to the compartment 41. In particular, the third 11 and fourth 11A rectilinear support elements should be located in positionlengthwise of the second peripheral element 3, which corresponds to entry 410 cover 41, 10 while the first and second rectilinear support elements 10A may be disposed in a suitable position along the second peripheral element 3 between input 410 and lower portion 411 compartment 41.

The wall structure further comprises, for the first 10, second 10A, third 11 and fourth 11 straight support elements, the corresponding first 100, second 100A, third 110 and fourth 110A end elements for engaging with the first end 101a of the corresponding rectilinear support element 10, 10A, 11 11A (see, in particular, Figs. 3, 4, 13, 15-17). The first end 101a of said corresponding rectilinear support element 10, 10A, 11, 11A is located on the opposite side with respect to the second end 101b of the corresponding rectilinear support element 10, 10A, 11, 11A (Figs. 3 and 4).

Each end element 100, 100A, 110, 110A, in turn, contains the main body 102 and the head 105 (see, in particular, Fig. 13, 15-17). The main body 102 has first axial connecting means 103. The first axial connecting means 103, by interacting along the direction from the first 101a to the second 101b end of the corresponding rectilinear support element 10, 10A, 11, 11A with the second axial connecting means 104 located at the first end 101a the corresponding rectilinear support element 10, 10A, 11, 11A, form a connection of the corresponding rectilinear support element 10, 10A, 11, 11A with the end element 100, 100A, 110, 110A (Fig. 13, 15-19). The direction from the first 101a to the second 101b end of the corresponding element 10, 10A, 11, 11A is the longitudinal direction of the most straight support element 10, 10A, 11, 11A (Fig. 3).

The head 105 comprises one or more engaging portions 106 for engagement with the corresponding elongated side 120 of the guide means 12.

Each elongated side 120 of the guiding means 12 extends along the longitudinal direction of the guiding means 12 themselves. The longitudinal direction of the guiding means 12 is the direction along which the door 16 slides when sliding along the guiding means 12 themselves. The guiding means 12 have a pair of elongated sides 120 parallel to each other and guide means located on opposite sides 12. A corresponding rectilinear support element 10, 10A, 11, 11A from each pair of rectilinear support elements 10, 10A, 11, 11A then engages with the elongated side 120 of the pair. In particular, this interaction uses the engaging portion 106 (or engaging portions 106) of the head 105, as well as the corresponding end members 100, 100A, 110, 110A. The elongated surface 123 of the guide means 12, on which the spring clips 27 are fixed, is preferably located between two opposite sides of the guide means 12, as a result of which there are places on the pair of elongated sides 120 that are parallel to each other (Fig. 9). Due to the connection between the guiding means 12 and the horizontal part 3 of the peripheral frame 1 (in particular, specifically, the second peripheral element 3), engagement between the engaging parts 106 of the heads 105 of the end elements 100, 100A, 110, 110A of the pairs of straight support elements 10, 10A, 11, 11A and corresponding elongated sides 120 of the guide means 12 becomes engaged between the pairs of straight support elements 10, 10A, 11, 11A and the horizontal part 3 of the peripheral frame 1 (in particular, the second peripheral element 3).

The connection of the rectilinear support element 10, 10A, 11, 11A with the corresponding end element 100, 100A, 110, 110A, by the interaction between the first 103 and second 104 axial connecting means, allows the elongation of the rectilinear support element 10, 10A, 11, 11A, which may have a length that is variable in direction from the first 101a to the second 101b end of the most straight support element 10, 10A, 11, 11A, and the straight support element 10, 10A, 11, 11A remains the same. This result can be obtained by simply combining a straight support element 10, 10A, 11, 11A with a corresponding end element 100, 100A, 110, 110A of various lengths. The accompanying Figs. 13, 15-17 illustrate various embodiments of the end element 100, 100A, 110, 110A, which, in particular embodiments, have different lengths. Thus, the wall structure has a degree of modularity with which the structures can be obtained, and can be adapted to doors of various heights using the same straight-line supporting elements 10, 10A, 11, 11A. The longitudinal dimensions of the end elements 100, 100A, 110, 110A are significantly smaller than the corresponding rectilinear support elements 10, 10A, 11, 11A and allow significant savings in storage space; in addition, they can be easily inserted as well as a “set” of end elements having different lengths into a box (or boxes) where various structural elements are stacked.

The wall structure also very much depends on the specific features of the peripheral elements 2, 3, 4 forming the frame 1, since the heads 105 of the end elements 100, 100A, 110, 110A are connected with the guiding means 12; therefore, one box can be sent that contains straight support elements 10, 10A, 11, 11A, corresponding end elements 100, 100A, 110, 110A, elements of the guide means 12, corresponding fastening means, and a little more. Frame 1 can be made in place in the usual way.

The second end 101b of each straight support element 10, 10A, 11, 11A may be operatively connected to another part of the wall structure. As best described below and as shown illustratively in FIG. 1, 2, 4, the specified other part of the wall structure may be another horizontal part 5 of the peripheral frame 1. In particular, specifically, another horizontal part 5 is located on the side peripheral frame 1 opposite the horizontal part 3. Said other horizontal part 5 may represent a horizontal surface conducive to the task of opening when the door 16 is actuated. Preferably, the other horizontal part 5 is a fourth peripheral element 5 of a large number Twa interconnected elongated elements. In particular, the fourth peripheral element 5 has a “C” -shaped cross section, and it also includes an intermediate part 6 from which flanges 7, 8 protrude from the side edges (these flanges also, in particular, belong to the corresponding opposite surfaces 7, 8 interconnected elongated frame elements 1). In particular, like the corresponding and opposite second peripheral element 3, the fourth peripheral element 5 may also have different lengths and / or be fixed in different positions with respect to the first 2 and fourth 4 peripheral elements to obtain peripheral frames 1 having different lengths. The fourth peripheral element 5 is so long that its free end 5A is separated from the second peripheral element 4 by a predetermined distance, preferably equal to the depth of the compartment 41 in which the door 16 should be placed. In particular, the specified distance may be greater than or equal to the width intended for the use of the sliding door 16. In general, the fourth peripheral element 5 is located in the lower part (namely, in accordance with the threshold, as a section of the lower longitudinal element).

The combination of the second end 101b of each rectilinear support element 10, 10A, 11, 11A with an additional part of the wall structure can be directly and / or indirectly obtained in various ways. In a preferred embodiment, it is prepared as follows. In addition, the wall structure further comprises, for the first 10, second 10A, third 11 and fourth 11A of straight support elements, the corresponding first 116, second 116A, third 117 and fourth 117A additional end element configured to interact with the second end 101b of the corresponding rectilinear supporting element 10, 10A, 11, 11A. In this regard, see, in particular, FIG. 3, 5 and 14. In particular, FIG. 14, even if illustrating a fragment of a second pair of straight support elements 11, 11A, which should be placed at the entrance 410 in the compartment 41, has corresponding additional end elements, indicated not only by the position numbers 117, 117A, characteristic of the additional end elements of the specified pair, but and (in brackets) the position numbers 116, 116A, which are characteristic of additional end elements that will be associated with the second end 101b of the straight support elements 10, 10A of the first pair, which should be placed between the input 410 and bo ttom portion 411 compartment 41; this indicates that in the embodiment shown in the drawings, the additional end elements of one of the two pairs of straight support elements may be identical to those of the other pair of straight support elements.

As shown in FIG. 14, each additional end member 116, 116A, 117, 117A, in turn, comprises an engaging portion 102 'and a mounting portion 105'. The engaging portion 102 'has an additional first axial connecting means 103'. The additional first axial connecting means 103 ', interacting in the direction from the first 101a to the second 101b end of the corresponding rectilinear supporting element 10, 10A, 11, 11A with the additional second axial connecting means 104' located on the second end 101b of the specified corresponding linear supporting element 10, 10A, 11, 11A, defines the connection of the specified corresponding element 10, 10A, 11, 11A with an additional end element 116, 116A, 117, 117A. Said compound is well isolated and can be seen, in particular, in FIG. 21. The mounting part 105 'is connected to the engaging part 102' (in particular, as a whole with it) and made with the possibility of engagement with the specified additional part of the wall structure, in particular, with the possibility of fastening to the latter, to fix the rectilinear support element 10 , 10A, 11, 11A, which is connected to the corresponding engaging portion 102 ', on said additional portion of the wall structure. Advantageously, the use of additional end elements 116, 116A, 117, 117A improves the modularity of the system, which ensures the maximum standardization of the production and sale of straight support elements 10, 10A, 11, 11A, which are no longer intended for any (independent: direct or indirect) connection with different parts of the peripheral frame 1, while this function is completely transferred to the end elements 100, 100A, 110, 110A and additional end elements 116, 116A, 117, 117A.

As shown illustratively in FIG. 14 and 21, in each pair of rectilinear support elements 10, 10A, 11, 11A facing each other, the fastening parts 105 ′ of the pair of corresponding additional end elements 116, 116 A, 117, 117A are preferably connected to each other to form “U” - shaped element. Thus made "U" -shaped element forms a type of spacing element associated with each pair of rectilinear support elements 10, 10A, 11, 11A so as to maintain the required distance between them, especially for the passage of the sliding door 16 between the same rectilinear support elements 10, 10A, 11, 11A. The so-called spacing element is also useful for keeping the same straight support elements 10, 10A, 11, 11A parallel to each other. The so-called spacer element can be used to correctly attach the straight support elements 10, 10A, 11, 11A to the floor or to any other horizontal surface, in particular when the horizontal part 5 of the peripheral frame 1 is not provided, or when it does not contain a fourth peripheral element 5 having a “C” -shaped cross section. When the peripheral frame 1 contains a horizontal portion 5, which, in turn, contains a fourth peripheral element 5 with a "C" -shaped cross-section, a spacing element that is formed by the fastening part 105 'of the pair of corresponding additional end elements 116, 116A, 117, 117A connected to each other with the formation of the "U" -shaped element, comes into contact with the Central part 6 of the fourth peripheral element 5 and is inserted between the flanges 7 and 8 of the fourth peripheral element 5. This also determines the insertion the respective parts of the straight support elements 10, 10A, 11, 11A between the same flanges 7 and 8 of the fourth peripheral element 5. Preferably, the lateral plane of the part of the straight support elements 10, 10A, 11, 11A is in contact with the flanges 7 and 8 of the fourth peripheral element 5. Recent conditions are shown schematically in FIG. 4, where the “U” -shaped spacing element is schematically represented by dashed lines in one of the pairs of straight support elements. The fastening parts 105 'have holes for inserting appropriate screws for fastening to the floor, or to any horizontal part of the peripheral frame 1.

The fastening parts 105 'of the pair of additional end elements 116, 116A, 117, 117A, corresponding to a pair of straight support elements 10, 10A, 11, 11A facing each other, can be made as a whole. However, it is preferable, as shown in particular in FIG. 3 and 13, the fastening parts 105 'of the pair of additional end elements 116, 116A, 117, 117A, corresponding to a pair of rectilinear support elements 10, 10A, 11, 11A facing each other, can be connected to each other so that the distance between the respective the engaging parts 102 'and, therefore, between the respective rectilinear support elements 10, 10A, 11, 11A can be changed (in particular, for installation in walls with different thicknesses). With specific reference to FIG. 14 and 21, each mounting portion 105 ′ comprises a first flange portion 160a and a second flange portion 160b located adjacent to the first and lying in a plane parallel to but different from the plane in which the first portion lies. The first flange portion 160a of one mounting portion 105 'is configured to overlap the second flange portion 160b of another mounting portion 105' to which it is to be connected, and vice versa. The mutual overlap of the flange parts 160a, 160b of the two fastening parts 105 ', which are to be joined together, can vary within certain, predetermined limits, in order to adjust the distance between the respective engaging parts 102'. In the embodiment shown in particular in FIG. 14 and 21, the degree of overlap can be selected from a variety of different values. In particular, mutually spaced seats 161 are located on the second flange portion 160b of each fastener portion 105 ', in each of which a protrusion 162 of the first flange portion 160a of each fastener portion 105' can be inserted (see detail I-I in FIG. 21). In particular, the protrusion 162 can be made on the tongue 163 of the first flange portion 160a. In this way, a temporary but strong connection is obtained between the two fastening parts 105 'before finally attaching them to the additional horizontal part of the peripheral frame 1.

In addition, the first axial connecting means 103, made on the main body 102 of the end element 100, 100A, 110, 110A, is made with the possibility of disconnecting from the second axial connecting means 104, made on the first end 101a of the corresponding rectilinear supporting element 10, 10A, 11, 11A. In addition, additional first axial connecting means 103 ', made on the engaging portion 102' of the additional end element 116, 116A, 117, 117A, are detachable from the additional second axial connecting means 104 'made on the second end 101b of the corresponding rectilinear support element 10, 10A, 11, 11A.

In a preferred embodiment of the present invention, shown in the accompanying drawings, on an end member 100, 100A, 110, 110A that engages with a first end 101a of a corresponding rectilinear support member 10, 10A, 11, 11A, the first axial connecting means 103 comprise at least one tooth 103. Accordingly, at the first end 101a of said corresponding rectilinear support element 10, 10A, 11, 11A, the corresponding second axial connecting means 104 comprise at least an elongated seating one hundred 104, which extends along the direction from the first 101 a to the second 101 b end of said corresponding element 10, 10A, 11, 11A. The tooth 103 is inserted into the corresponding elongated seat 104; said corresponding element 10, 10A, 11, 11A is thus connected to the end element 100, 100A, 110, 110A, in particular, at its first end 101a, according to the type of plug-socket (see, in particular, Fig. 19 )

Preferably (as shown, in particular in FIGS. 13, 15-18), the first axial connecting means 103 comprise several teeth 103, and the second axial connecting means 104 comprise several elongated seats 104 that extend along the first direction from the first 101a to the second 101b end of said corresponding element 10, 10A, 11, 11A. Each tooth 103 is inserted into a corresponding elongated seat 104; said corresponding rectilinear support element 10, 10A, 11, 11A is thus connected to the end element 100, 100A, 110, 110A, in particular, at its first end 101a, in the form of a plug-socket.

In particular, at the first 100, second 100A, third 110 and fourth 110A end elements, said at least one tooth 103 (or several teeth 103), being part of the first axial connecting means 103, protrudes from the main body 102 and, preferably, it is integral part. In the embodiment shown in FIG. 13 and 15 (which illustrate end elements 100, 100A, 110, 110A having a minimum length in the direction from the first 101a to the second 101b end of the corresponding rectilinear support element 10, 10A, 11, 11A) the teeth 103 (or tooth 103) essentially form (forms) the main body 102. In the cases shown in FIG. 16, 17 and 18, the main body 102 also comprises, in addition to the teeth 103, extending along the direction from the first 101a to the second 101b end of the corresponding rectilinear support element 10, 10A, 11, 11A. The specified continuation has a different length, in order to adapt the wall structure to the doors 16 of different heights, while maintaining, without changes, the straight support elements 10, 10A, 11, 11A.

Preferably, the elongated seats 104 of the second axial connecting means 104 extend along the entire length of the corresponding rectilinear support element 10, 10A, 11, 11A from the first end 101a to the second end 101b. Thus, the straight support elements 10, 10A, 11, 11A can be directly made in the form of simple sections without the need for any specific work operation at their ends. Secondly, in particular and preferably, the straight support elements 10, 10A, 11, 11A can be directly made in the form of stamped profiles. Alternatively, the straight support elements 10, 10A, 11, 11A can also be directly formed as sections obtained by folding and molding from one elongated sheet.

In a preferred embodiment of the present invention, shown in particular in the accompanying FIGS. 14 and 21, on an additional end member 116, 116A, 117, 117A that engages with the second end 101b of the corresponding rectilinear support element 10, 10A, 11, 11A, the additional first axial connecting means 103 'comprises at least one further tooth 103 '. Accordingly, at the second end 101b of said corresponding supporting element 10, 10A, 11, 11A, the respective second second axial connecting means 104 ′ comprise at least an additional elongated seat 104 ′ that extends along the direction from the first 101a to the second 101b of the end of said corresponding supporting element 10, 10A, 11, 11A. An additional tooth 103 'is inserted into the corresponding additional elongated seat 104' (Fig. 21); thus, the element 10, 10A, 11, 11A is connected to the additional end element 116, 116A, 117, 117A, in particular, at its second end 101b, the type of plug-socket.

Preferably, the additional first axial connecting means 103 'contains several additional teeth 103', and the additional second axial connecting means 104 'contain several corresponding additional elongated seats 104' that extend along the direction from the first 101a to the second 101b of the end of said corresponding element 10, 10A, 11, 11A. Each additional tooth 103 'is inserted into a corresponding additional elongated seat 104' (Fig. 21); said corresponding rectilinear support element 10, 10A, 11, 11A is thus connected to an additional end element 116, 116A, 117, 117A, in particular at its second end 101b, in the form of a plug-socket.

In particular, at first 116, second 116A, third 117 and fourth 117A additional end element, said at least one additional tooth 103 '(or several additional teeth 103'), which is part of the additional first axial connecting means 103 ', protrudes from the engaging part 102 'and, preferably, is an integral part thereof. The accompanying drawings illustrate the case where an additional tooth (or additional teeth) 103 ′ constitutes a large part of the engaging portion 102 ′. Additional end elements 116, 116A, 117, 117A of different lengths can be made in any case, in particular, having engaging portions 102 '(of which protruding additional tooth 103' or additional teeth 103 ') of different lengths, to add another degree of freedom for the possible adaptation of the wall structure to doors 16 of various heights.

Preferably, when the elongated seats 104 of the second axial connecting means 104 extend along the entire length of the corresponding support element 10, 10A, 11, 11A from the first end 101a to the second end 101b, the additional elongated seats 104 'of the additional second axial connecting means 104' coincide with elongated seats 104 of the second axial connecting means 104. Thus, in one production step, the straight support elements 10, 10A, 11, 11A (in the form of stamped profiles or in sections, obtained bending and molding from one elongated sheet) can be made with the possibility of inserting teeth 103, 103 'of the end elements of both types, without the need for any special working operation at the ends 101a, 101b.

In general, regardless of the type of end element, it is preferable:

- on the end element 100, 100A, 110, 110A, 116, 116A, 117, 117A, the corresponding first axial connecting means 103, 103 'comprise at least one tooth 103, 103', preferably several teeth 103, 103 ';

- at the end 101a, 101b of the corresponding rectilinear support element 10, 10A, 11, 11A associated with the end element 100, 100A, 110, 110A, 116, 116A, 117, 117A, the corresponding second axial connecting means 104, 104 'contain an elongated landing a location 104, 104 ', preferably several elongated seats 104, 104' that extend (preferably extend) along the direction from the first 101a to the second 101b end of the support member 10, 10A, 11, 11A.

Each tooth 103, 103 'is inserted into a corresponding elongated seat 104, 104', while the corresponding rectilinear support element 10, 10A, 11, 11A is thus connected to the end element 100, 100A, 110, 110A, 116, 116A, 117, 117A by type of plug-socket.

In general, the type of plug-to-socket connection between the end element and the corresponding end of the corresponding rectilinear support element makes the connection itself very simple and efficient.

Preferably, as shown in the drawings, there are two types of straight support elements 10, 10A, 11, 11A, in accordance with their position in use. In particular (and with reference, in particular, to FIGS. 5, 13 and 15), each straight support element 10, 10A, 11, 11A extends from its first 101a to its second 101b end, having a cross section containing a central part 43 with an inner side 44 and an outer side 45. Wall panels 14, 15 are adjacent to the outer sides 45. The elongated seats 104 and additional elongated seats 104 'extend between the inner 44 and outer 45 sides. Preferably, in a pair of rectilinear support elements 10, 10A, 11, 11A, which should be located at the entrance 410 in the compartment 41 for receiving the door 16, the Central section 43 of the cross-section of the rectilinear support elements 11, 11A extends along the side that should be oriented to the outer side of the compartment 41, in the supporting and orienting structure 46 for possible finishing of the entrance 410 of the compartment 41 itself. Passing along the entire corresponding rectilinear supporting element 11, 11A, this structure 46 contribute to the formation of the corresponding profile Rowan support and alignment ribs 46. As shown in particular in FIG. 16, 17 and 18, when end elements 100, 100A, 110, 110A are used having a length longer than standard, a continuation part of the main body 102 located between the first axial connecting means 103 (in particular, preferably between the tooth 103 or the teeth 103) and the corresponding head 105, passes below the guide means 12 and, thus, creates a gap between the straight support elements 11, 11A of the pair installed at the entrance 410 in the compartment 41, and the guide means 12 itself, where the wall structure cannot have any supporting and an orienting structure for possible finishing of the entrance 410 to the compartment 41. Preferably, in this case, the wall structure comprises segments 460 of an additional profiled element having the same cross section as the supporting and orienting structure 46 and, therefore, the same cross section as the corresponding supporting and orienting rib 46. These segments 460 can be slid into the guide rib 461 located on the continuation of the main body 102 of the end elements 100, 100A, 110, 110A (FIG. 18), thus completing the supporting and orienting rib 46 of the straight support elements 11, 11A in a pair, which is located at the entrance 410 to the compartment 41.

As already mentioned, the head 105 of each end element 100, 100A, 110, 110A contains one or more engaging portions 106 for engagement with the corresponding elongated side 120 of the guide means 12. In the preferred embodiment shown in the drawings, the engagement of the head 105 with the corresponding the elongated side 120 of the guide means 12 is obtained using the corresponding one or more engaging parts 106 as follows. With reference in particular to FIG. 13, 15, 19 and 21, on the engaging parts 106 and on the corresponding elongated side 120 of the guide means 12, interacting means 170 are arranged. These interacting means 170, when the engaging parts 106 are engaged with the corresponding elongated side 120 of the guiding means 12, slides with the end element 100, 100A, 110, 110A and connected to it, and the corresponding rectilinear support element 10, 10A, 11, 11A with the guiding means 12 before finally fixing, while preventing, at least as the movement of the end element 100, 100A, 110, 110A with the corresponding rectilinear support element 10, 10A, 11, 11A attached thereto in the direction from the first 101a to the second 101b end of said corresponding element 10, 10A, 11, 11A, so and rotating said corresponding element 10, 10A, 11, 11A around its second end 101b.

Thus, by allowing the end element 100, 100A, 110, 110A to slide along the corresponding elongated side 120 of the guide means 12, the position of the pair of straight support elements 10, 10A, 11, 11A along the guide means 12 can be changed, even before their position is fixed on this facility. Thus, changing the size of the compartment 41 for accommodating doors 16 of different widths is easy and does not require any additional element.

Preventing at least the movement of the end element 100, 100A, 110, 110A in 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, as soon as the engaging parts 106 are engaged with the elongated side 120 such Thus, in order to activate the action of the interacting means 170, it allows the sliding operation to be carried out without tearing off the straight support element 10, 10A, 11, 11A from the elongated side 120 of the guide means 12.

In FIG. 22 shows various parts of the elements on which the interacting means 170 is made. In FIG. 19 shows the obtained compound, and the action of the interacting means 170 can be seen.

When also the second end 101b of each rectilinear support element 10, 10A, 11, 11A is operatively connected with the additional horizontal part of the wall structure (in particular, with the additional horizontal part 5 of the peripheral frame 1; in particular, even more specifically, with the fourth peripheral element 5 ), so as to be able to slide along the indicated additional horizontal part of the wall structure (in particular, for example, by means of fastening parts 105 'supported by additional parts of the wall con but not yet attached to it), the restriction created by the mutual action of the interacting means 107 holds each rectilinear support element 10, 10A, 11, 11A in a predetermined position, while simultaneously allowing it to slide along the guide element 12, without the need to manually maintain him or support it manually adjacent to the guide means 12 itself.

As already noted, in a preferred embodiment, the fastening parts 105 'of the additional end elements 116, 116A, 117, 117A associated with each pair of rectilinear support elements 10, 10A, 11, 11A facing each other are connected to each other to form " U-shaped element, which, thus, forms a kind of spacing element associated with each pair of straight support elements 10, 10A, 11, 11A. In this case, each pair of rectilinear support elements 10, 10A, 11, 11A may be in equilibrium, supported by a “U” -shaped element formed by additional end elements 116, 116A, 117, 117A, even before the fastening parts 105 'are fixed on an additional part of the wall structure. Due to the action of the interacting means 107, the engagement of the heads 105 of the end elements 100, 100A, 110, 110A with the corresponding elongated sides 120 of the guide means 12 prevents the linear support elements 10, 10A, 11, 11A from tilting in a plane perpendicular to the direction of the continuation of the guide means 12. However, the sliding movement of a pair of straight support elements 10, 10A, 11, 11A along the elongated sides 120 of the guide means 12 is allowed in a substantially stable manner and without additional auxiliary media STV.

As shown in FIG. 13, 15, 19, and 22, the interacting means 107 comprise a first contact portion 108a of the engaging portions 106 located distally with respect to the main body 102 and to the longitudinal axis 121 of the guiding means 12 (indicated by dot-and-dot lines in FIGS. 6 and 13 and circled by a dot on Fig. 7, 19 and 22, where it is perpendicular to the plane of the sheet). The first contact portion 108a is in contact with the corresponding first contact surface 122a of the corresponding elongated side 120 located distally from the longitudinal axis 121 of the guide means 12. The interacting means 107 further comprise a second contact part 108b of the engaging parts 106 located proximal to the main the housing 102 and to the longitudinal axis 121 of the guide means 12. The second contact portion 108b is in contact with the corresponding second contact surface 122b of the corresponding the long side 120 located proximally with respect to the longitudinal axis 121 of the guide means 12. In particular, the first contact parts 108a and second 108b are disposed relative to one another at the extreme positions of the diagonal line that extends across the direction of travel of the guide means 12 (in particular preferably which lies in a plane perpendicular to the direction of passage of the guide means 12). The longitudinal axis 121 of the guide means 12 is parallel to the direction of passage of the guide means 12.

The second contact portion 108b extends into a portion 109 that has a “Corresponding cross-section in a plane perpendicular to the longitudinal axis 121 of the guide means 12. The corresponding portion of the corresponding elongated side 120 of the guide means 12 is inserted into the“ C ”-shaped portion 109.

In addition, in general, the interacting means 107 comprise an elastically deformable portion 111 of the head 105, which has one or more protrusions 112 configured to resiliently fit into respective seats 131 of the corresponding elongated side 120. Preferably, as illustrated in an illustrative and non-limiting manner only. in the accompanying drawings, which show a preferred embodiment of the invention, an elastically deformable part 111 of the head 105 is located on the first contact part 108a of the engaging pieces 106. Preferably, the elastically deformable portion 111 of the head 105 coincides with the first contact portion 108a of the engaging pieces 106.

As shown in the drawings, the head 105 may comprise several parts 114 spaced apart from each other along the corresponding elongated side 120 of the guide means 12.

Preferably, the wall structure in accordance with the present invention further comprises a lateral extension 115 of the head 105 inserted as a spacer between the head 105 and the corresponding elongated side 120 of the guide means 12 (Fig. 20, 23-25). The lateral extension 115 has an additional engaging portion 106 ′ adapted to engage with the corresponding elongated side 120 of the guide means 12 instead of the engaging portions 106 of the head 105 and serving the same purpose. In particular, advantageously, said additional engaging portion 106 ′ comprises parts that are identical to the engaging portions 106 of the head 105.

Thus, by making the wall structure with a lateral extension 115 for the head 105 of each end element 100, 100A, 110, 110A, it is possible to adapt the wall structure to walls of different thicknesses. In particular, by varying the thickness of the lateral extension 115, structures that are suitable for any desired thickness can be obtained without interfering with the basic elements of the structure itself. In particular, as shown in the drawings, the lateral extension 115 can be connected to the engaging portions 106 of the head 105 through its side 118 opposite to where the additional engaging portions 106 'are located (in particular, by moving as shown by the arrow in Fig. 24 and 25). Preferably, the extension 115 of the head 105 has latched engaging means 119 located on the side 118 opposite to where the additional engaging parts 106 are located and interacting with corresponding engaging means 119 'located on the head 105. In particular (Figs. 20 and 24 ), the snap engaging means 119 comprise two elastically deformable flanges 164 that have engaging teeth 165. The flanges 164 can be resiliently inserted into the through seats 166 provided in the head 105 to a depth sufficient to th to the ends 166 of the flanges out of the through seats 166 and expanded, resulting in snapping engagement and abutment teeth 165 in the holding surface 167 on the head 105 (FIG. 20).

With specific reference to FIG. 3, 4, 11, 26 and 27, the wall structure according to the invention further comprises at least two finishing lintels 24, 25 of a predetermined length, which with their side should be connected with the guiding means 12 in the area where the guiding means 12 can be seen to the user, for closing and protecting the guide means 12 themselves and for finishing purposes. In particular, in a wall structure with a sliding door 16 and a compartment 41 for accommodating the door 16, the finishing bridges 24, 25 are connected to the guiding means outside the compartment 41. The finishing bridges 24, 25 are connected to the elongated sides 120 of the guiding means 12. In particular, the guide bridges 24, 25 are located outside the chamber 41, immediately after the straight support elements 11, 11A of the pair, which limits the entrance 410 into the compartment 41. Being connected with the elongated sides 120 of the guide means 12, the finishing jumpers 24, 25 are located directly After the end elements 110, 110A connected to the first end 101 a of the straight support elements 11, 11A, there are pairs that limit the entrance 410 to the compartment 41. The finishing jumpers 24, 25 can be long enough to cover the entire part of the opening intended for closing door 16 (or door 16, as in the case of a double door, as shown in Fig. 2), which is in sight. Alternatively, the length of said part in view can be covered by several finishing bridges 24 on one side of the guide means 12 and corresponding finishing bridges 25 on the other side of the guide means 12. In addition, the finishing bridges 24, 25 are “1 _” -shaped a cross section 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 engaging means for engaging with the elongated sides 120 of the guide means 12. When the short side 240, 250 of the finishing jumpers 24, 25 is connected with the elongated sides 120 (Fig. 11, Fig. 26, part "(i)", Fig. 27 (a)), the finishing jumpers 24, 25 are in the first position of the minimum width . When the long side 241, 251 of the finishing bridges 24, 25 is connected to the elongated sides 120 (FIG. 26, part “(ii)”, FIG. 27 (b)), the finishing bridges 24, 25 are in a second maximum width position. Thus, the same finishing elements 24, 25 can be adapted to the wall structure of various thicknesses. In particular, mainly: the first position of the minimum width may correspond to the width of the heads 105 of the end elements 100, 100A, 110, 110A; the second position of the maximum width may correspond to the width of the heads 105 of the end elements 100, 100A, 110, 110A, increased by the width of the side extensions 115. The first position of the minimum width may correspond to the first increased position of the spring clips 27; the second position of the maximum width may correspond to the second enlarged position of the spring clips 27. In the embodiment shown in the drawings, the free end of the short side 240, 250 has a corresponding protrusion 242, 252, which, along the longitudinal direction of the finishing bridge 24, 25, becomes the corresponding rib 242 , 252, configured to be inserted into the first longitudinal seat 124 of the corresponding elongated side 120 of the guide means 12, and also passing along the guide means 12. the phenomenon may be a snap along a direction that is transverse to the longitudinal axis of the guide means 12. The insert may be a slip along the direction of the axis of the guide means 12, starting from the end of the guide means 12. When the rib 242, 252 of the short side 240, 250 is inserted into the first longitudinal landing place 124, the finishing jumper 24, 25 is in the first position of the minimum width. In the embodiment shown in the drawings, the free end of the long side 241, 251 has a corresponding protrusion 243, 253, which, along the longitudinal direction of the finishing bridge 24, 25, becomes the corresponding rib 243, 253, made with the possibility of inserting in an additional longitudinal seat elongated seat 120 of the guide means 12, as well as passing along the guide means 12. The insert can be a snap along a direction that is transverse to the longitudinal si of the guiding means 12. The insert may be sliding along the axis direction of the guiding means 12, starting from the end of the guiding means 12. When the rib 243, 253 of the long side 241, 251 is inserted into an additional longitudinal seat, the finishing bridge 24, 25 is in the second position maximum width. Preferably, the additional longitudinal seat coincides with the first elongated seat 124. Advantageously, each elongated side 120 of the guiding means 12 has a second longitudinal seat 125 parallel to the first longitudinal seat 124 and positioned relative to the latter such that when the finishing bridge 24, 25 is in the first position of the minimum width, inserting the ribs 242, 252 of the short side 240, 250 into the first longitudinal seat 124 of the corresponding elongated one These 120 correspond to the insertion of the ribs 243, 253 of the long side 241, 251 in the second longitudinal seat 125 of the corresponding elongated side 120. Preferably, the second longitudinal seat 125 is made corresponding to the seat 113, where one or more protrusions 112 of the elastically deformable part 111 of the head 105 of the end elements 100, 100A, 110, 110A are made with the possibility of insertion. Preferably, the first longitudinal seat 124 is provided in the portion of the elongated side 120 of the guide means 12, which can be inserted into the “C” -shaped portion 109, which extends the second contact portion 108b of the engaging portions 106 of the engaging portions 106 of the head 105 of the end elements 100, 100A, 110, 110A . In addition, both in the first position of the minimum width and in the second position of the maximum width, the finishing lintels 24, 25 located on two opposite elongated sides 120 of the guide means 12 are arranged symmetrically with respect to each other with respect to the middle plane of the guide means 12. Preferably , the cross section of the finishing lintels 24, 25 is the same and constant over their entire length. Thus, all the required finishing jumpers 24, 25 can be obtained with a single profiled element of a given section, simply cutting the profiled element in accordance with the requirement. Various segments can then be used at different positions shown in FIG. 26 and 27, simply rotating them accordingly. The profiled element can be obtained by extrusion. Preferably, the shaped element is made of plastic.

A variant of the wall construction, which is suitable for several types of doors 16 (not only for a sliding door, but also for sliding hinged doors and folding doors and, in general, for all those cases in which a door requires a means of facilitating its sliding movement in horizontal direction) can be particularly versatile, at least in terms of modularity, decoration and various combinations of use. In particular, this embodiment is a solution that can become extremely useful in all those cases in which the guide structure, which allows the sliding movement of the door 16, must be extended or adapted. The specific case when the wall structure should serve two doors, which, when they are closed, are adjacent to each other. In FIG. 2 shows a peripheral frame suitable for a wall structure for a double door 16. Although FIG. 2 illustrates the case of sliding doors in the strict sense of the word, the solution that we will describe, as a rule, applies to all those situations in which sliding movement should be notified to door 16, in particular, not only sliding doors in the strict sense of the word, but also sliding hinged doors and folding doors (the latter, for the purposes of the present invention, are essentially sliding hinged doors, in the sense that they are doors with several sections, each of which, in turn, is a etsya sliding swing section).

The following description will be made with reference to the accompanying drawings, and in particular to FIG. 1, 2, 11, 28-31, wherein the improved wall construction with a sliding door or for a sliding swing door comprises a rail section 21 (in particular, the rail section 21 discussed in the entire preceding description, in accordance with all possible embodiments) for connecting with the horizontal part 3 of the peripheral frame 1 (in particular, with the horizontal part 3 of the peripheral frame 1, as described above, in accordance with all possible embodiments). The rail section 21 allows the sliding or sliding swing or folding door 16 to slide in. The wall structure further comprises an end closure element 70 for the rail section 21, which must be connected to the first end 200 of the rail section 21. The rail section 21 is connected to the end closure element 70 using the first connecting system 90, which is located on the first end 200 of the rail section 21 and interacts with the second connecting system 91 located on the first side 71 of the end closure element 70. The wall structure further comprises an additional element 80, which, in turn, is connected to the end closure element 70 using the third connection system 92. The third connection system 92 is located on the second side 72 of the end closure element 70, distal from the first side 71, and interacts with the fourth connecting system 93, located on the second side 82 of the additional element 80, distally from the first side 81 of the most additional element 80. The additional element 80 may be a finishing plug, the first side 81 of which, in turn, is its finishing side. The additional element 80 may be a connecting part with the first side 81, having, in this case, the corresponding fifth connecting system 94 for connecting the additional element 80 with other parts of the wall structure.

Thus, simply by changing the additional element 80, either the rail section 21 can be finished at its first end 200, or a joint can be obtained between the rail section 21 and other parts of the wall structure, for example, another rail section, to obtain a wall structure with double door.

In addition, the second connecting system 91 comprises at least one tooth 95, preferably a plurality of teeth 95, protruding from the first side 71 of the end closure element 70 from the second side 72 of the end closure element 70. The first connection system 90 contains at least one elongated seat 96, preferably several elongated seats 96 located on the first end 200 of the rail section 21. The specified at least one elongated seat 96 (or several elongated seats m eat 96) the first end 200 of the rail section 21 extends in a direction from the first 200 to the second 201 of the end of the rail section 21 (see also Fig. 6). A tooth 95, or teeth 95, is inserted / inserted into an elongated seat 96 or elongated seats 96, and preferably, each tooth 95 is located in a corresponding elongated seat 96. Thus, the end cover member 70 can be attached to the rail section 21 according to the type of plug-in socket.

Preferably, the third connecting system 92 comprises at least one spike 97, or a groove 97 ', located on the second side 72 of the end closure member 70. The fourth connecting system 93, in turn, contains at least one groove 98, or the spike 98' located on the second side 82 of the additional element 80. A spike 97, or times 97 ', of the third connecting system 92 is connected, respectively, with a groove 98 or a spike 98' of the fourth connecting system 93.

As shown in particular in FIG. 11, preferably the third connecting system 92 comprises at least one spike 97 and at least one groove 97 'located on the second side 72 of the end closure element 70. In this case, the fourth connecting system 93, in turn, contains at least one groove 98 and at least one spike 98 'located on the second side 82 of the additional element 80. The spike 97 and the groove 97' of the third connecting system 92 are connected, respectively, with the groove 98 and with the spike 98 'of the fourth connecting system 93. Advantageously, as shown on h rtezhah (see in particular Figures 11, 29, 32.), the connection between tenon 97; 98 'and the corresponding groove 98; 97 'implements a dovetail type compound. Preferably, insertion of a spike 97; 98 'in the corresponding groove 98; 97 'is carried out by a movement comprising at least a final step in which the additional element 80 is moved relative to the end closure element 70 along a direction that is transverse, preferably perpendicular, to the direction from the first 71 to the second 72 side of the end closure element 70 and / or from the second 82 to the first 81 side of the additional member 80 (see arrow marked “Y” in FIG. 28 and FIG. 31). In particular, advantageously, the connection can be obtained by bringing an additional element 80 near the end closure element 70 in the direction from the second 72 to the first 71 side of the end closure element 70, while supporting both components with a slight offset from each other in the transverse direction Y After partial interpenetration of the end closure element 70 and the additional element 80 is obtained, which is sufficient to bring the spikes 97; 98 'in accordance with the corresponding grooves 97'; 98, the two components move in the transverse direction Y to finally engage the spikes 97; 98 'with corresponding grooves 97'; 98.

After engaging with each other, the end closure element 70 and the corresponding additional element 80 can be fastened together using appropriate fastening means, for example, one or more screws.

As shown in FIG. 11 (detail "(a)") and FIG. 28-30, the additional element 80 may have one or more mounting flanges 94 'for attaching to the peripheral element 2 of the peripheral frame 1 of the wall structure (in particular, with reference to the previous description, this may be the first peripheral element 2 of the peripheral frame 1). The fastening can be carried out using (not shown) screws that can be inserted into the holes of the mounting flanges 94 '.

Advantageously (as shown, in particular in Fig. 11, part "(b)", and Figs. 31-33), the additional element 80 has a corresponding fifth connecting system 94 located on the first side 81. The wall structure further comprises an additional rail section 21 ′ (shown schematically in dashed lines in FIG. 33) for connecting to the horizontal portion 3 of the peripheral frame 1 (see also the schematic representation in FIG. 34). The additional rail section 21 'is connected to the additional element 80 via a sixth connecting system 99, which is located at the second end 201' of the additional rail section 21 'distally from the first end 200' of the additional rail section 21 '. The sixth connecting system 99 cooperates with the fifth connecting system 94 located on the first side 81 of the additional element 80. The additional element 80, thus, is another end locking element for the additional rail section 21 '.

Additional rail section 21 'can be used to provide sliding movement of an additional sliding or sliding swing or folding door, which is located next to the first door. Thus, the wall structure with a double door can be easily obtained with the same peripheral frame 1.

As shown in the drawings, predominantly the fifth connecting system 94 is identical to the second connecting system 91, the fourth connecting system 93 is identical to the third connecting system 92. In this case, preferably, the end closure element 70 and the additional element 80 are identical to each other. Thus, a large number of identical elements can be used to connect the various rail sections 21, 21 ′ to each other. In addition, the sixth connecting system 99 is identical to the first connecting system 90.

When the first connecting system has elongated seats 96, the rail section 21 can be obtained by extrusion (in particular, it can be obtained together with the corresponding support element 22 when the latter is present) and may have a cross section in which an elongated landing is obtained place 96. Thus, either the end closure elements 70 or the corresponding additional elements 80 can be connected to both ends 200, 201 of the rail section 21. Thus, a large number of rail sections 21, 21 'can be easily obtained by cutting one profiled element in accordance with the requirements. In addition, the same elements can be used to connect several rail sections 21, 21 'to each other.

In addition, the wall structure contains:

- several rail sections 21, 21 ', intended for connection with the horizontal part 3 of the peripheral frame 1;
