Detailed description of some preferred embodiments

With reference to the above figures, a false ceiling 1 is described installed in a space S, generally an open space, in correspondence of a ceiling C. In a preferred but not exclusive embodiment of the invention, such false ceiling 1 may be an integral part of a system 100 for varying the configuration of the space S.

Essentially, the false ceiling 1 may include a plurality of supporting bandrasters 10 connected in a per se known manner to the ceiling C, a plurality of ceiling panels P and a plurality of elements 20 for the mutual connection of the panels P and the supporting bandrasters 10.

The bandraster 10 may comprise a pair of side walls 11, 12 facing each other and an upper wall 13 to be faced towards the ceiling C.

Suitably, the side walls 11, 12 and the upper wall 13 can cooperate with each other to define a compartment 14, open at the bottom side to removably house one or more accessories that perform one or more functions in the space S, for example a cover element 30 fixable in the compartment by means of snap-fitting fastening elements 34', 34" placed at the outer surface 361', 361" of transverse elements 36', 36", or a lighting device 31, a system 32 for holding one or more partition walls or like accessories.

The false ceiling 1 is a multifunctional one, that is, it is able to house a plurality of accessories in a removable way to ensure the user the possibility to change the configuration of the space S according to need.

For example, in the case of space S of the open space type, the false ceiling 1 may provide a plurality of bandrasters 10 that include service accessories, such as lighting devices, fire alarms, cable duct and the like. The bandrasters 10 may be closed by cover elements 30.

In case of need, for example in the case it is necessary to divide the space S of the open space type in a plurality of compartments, it is sufficient to remove the cover element 30 from one or more of the bandrasters 10 and insert the system 32 to hold one or more partition walls, which may for example be made of glass or plasterboard. The other bandrasters 10, in which the system 32 is not inserted, are provided with the covering element 30, which may be transparent or not to allow the passage of the light rays of the lighting device 31. If necessary, data cables, telephone cables or like cables can be inserted within the cable ducts.

Each of the side walls 11, 12 of the bandraster 10 may include a first edge 1100', 1200' facing the ceiling C and a second edge 1100", 1200" opposite to it and facing downward.

The side walls 11, 12 can have any configuration.

For example, in a preferred but not exclusive embodiment, the side walls 11, 12 may be rectilinear and parallel each other, as for example taught by the documents WO2009/153673 and WO2013/050963.

On the other hand, in a preferred but not exclusive embodiment, the side walls 11,

12 may be divided into respective upper portions 1 , 12' and lower portions 11", 12" between facing each other, preferably substantially parallel to each other.

Each of the upper and lower portions 1 , 12'; 11", 12" may have respective inner surfaces 110', 120'; 110", 120" and the outer surfaces 111', 121'; 111", 121", the outer surfaces 111" and 121" being susceptible to remain facing to the panels P.

The distance d" between the lower portions 11", 12" may be greater than the distance d' between the upper portions 11', 12', so that the compartment 14 remains divided into a top narrow area 14' and an enlarged lower area 14".

Advantageously, the ratio between the distances d" : d' may be greater than or equal to 1,1 : 1, preferably greater than or equal to 1,25 : 1 and even more preferably greater than or equal to 1,4 : 1.

Preferably, this ratio d" : d' is about 1,45 : 1.

The distance d" between the lower portions 11", 12" of said lateral walls 11, 12 may be preferably close to 100 mm.

Suitably, the height of the narrow upper area 14' and of the lower enlarged one 14" is sufficient to house respective first and second accessories, for example, the lighting device 31 and the system 32 as shown in FIG. 2 or respectively the lighting device 31 and the cover element 30 as shown in FIG. 1.

It is understood that each area 14', 14" may include one or more accessories, depending on the configuration of the latter.

It also understood that one of the areas 14', 14" or both areas may be left empty for the passage of cables or ducts. If necessary, in this case the lower area houses a covering element 30 to hide the view of the cables or ducts.

Of course, the ratio between the heights of the two areas 14', 14"determines the type of accessories to be inserted.

In general, the relationship between the height H' of the upper narrow area 14' and the H" of the enlarged lower are 14" may be between 0,5 : 1 and 4 : 1, preferably between 0,75 : 1 and 3,5 : 1 and more preferably between 0,9 : 1 and 3 : 1.

In a first preferred but not exclusive embodiment of the bandraster 10, shown for example in FIG. 4, the two areas 14', 14" may have comparable heights.

Preferably, therefore, in this embodiment the ratio between the height H' of the narrow upper area 14' and the height H" of the enlarged lower area 14" may be between 0,5 : 1 and 1 : 0,5, preferably between 0,75 : 1 and 1 : 0,75 and even more preferably between 0,85 : 1 and 1 : 0,85.

On the other hand, In another preferred but not exclusive embodiment of the bandraster 10, shown for example in FIG. 5a, the narrow upper area 14' may have significantly greater height than that of the enlarged lower area 14". This allows to insert within the narrow area upper area if needed bulky accessories.

Preferably, therefore, in this embodiment, the ratio between the height H' of the narrow upper area 14' and the height H" of the enlarged lower area 14" may be between 4 : 1 and 2 : 1, preferably between 3,5 : 1 and 2,5 : 1 and even more preferably between 3,2 : 1 and 1 : 2,8.

In order to removably house the accessories, each of the areas 14', 14" may have respective first and second snap-fitting means, for example a respective first and second pair of male or female elements 15', 15" susceptible to snap-fittingly house respective accessories, for example the lighting device 31 and the cover element 30 as shown in FIG. 1. It is understood that the cover element 30 may be opaque or transparent to allow the passage of light rays of the lighting device 31.

Preferably, the inner surfaces 110'; 120' of the upper portion 11', 12' of the side walls 11, 12 may include first snap-fitting means, for example the couple of male or female elements 15', while the inner surfaces 110"; 120" of the lower portion 11", 12" of the side walls 11, 12 may include second snap-fitting means, for example the couple of male or female elements 15".

Conveniently, the first and second snap-fitting means may be defined by female snd elements 15', 15", as shown in the accompanying figures.

Preferably, the first and second snap-fitting means, for example the first and second pair of male or female elements 15', 15", may be configured so that accessories once inserted within the compartment 14 do not protrude from the same. Preferably, therefore, also the accessories present a configuration adapted to that function.

In a preferred but not exclusive embodiment, to facilitate the snap fit of the accessories within the compartment 14, the latter can be provided with female or male elements 15"', 15"" susceptible to cooperate with the male or female elements 15', 15".

Thanks to the above configuration, the bandraster 10 allow to concealably house a plurality of accessories, in particular partition walls of any kind and width.

By contrast, the bandrasters of the prior art, for example that of patent EP2313572, is too narrow for housing in an integrated manner all kinds of walls available on the market. With such a bandraster, for example, it is not possible to house in an integrated manner plasterboard walls, the thickness of which is equal to the distance between the support member of the ceiling panels.

Between the upper and lower portions 11', 12'; 11", 12" respective connection areas 16', 16" may be interposed, preferably substantially perpendicular to the former, each comprising a lower surface 160', 160" at the inner side of the compartment 14 and an upper surface 16 , 161" external to the same compartment 14 susceptible to remain facing the ceiling C to support the connecting element 20 of the panels P.

Externally to the bandraster 10 seats 17', 17" may be provided for the connection elements 20 of the panels P. These seats can be placed in correspondence of the outer surfaces 161', 161", as shown for example in FIGS. 5a and 5b, or in correspondence of the outer surfaces 111", 121", as shown for example in FIGS. 3a and 3b.

Advantageously, the outer surfaces 111', 121' of the upper portions 11', 12' of the side walls 11, 12 may include respective longitudinal rails 40', 40" for one or more elements of mutual connection of two or more bandrasters 10, for example metal brackets, not shown since known per se. By means of the rails 40', 40" is then possible to connect bandrasters 10 incident each other, for example at 90° relative to one another. Each of the longitudinal rails 40', 40" may be defined by upper guides 41', 41" and lower guides 42', 42", which face each other.

In a preferred but not exclusive embodiment, shown for example in FIGS. 5a and 5b, each of the lower guides 42', 42" may also include the seat 17', 17" for the connecting elements 20. Moreover, each of the upper guides 41', 41" may preferably include a respective shoulder 43', 43" which can cooperate with a corresponding support element 50', 50" to define a seat 44', 44" housing a sound-proofed wall PI, as shown in FIG. 2.

More particularly, the upper wall 13 includes a pair of projections 5 , 51" extending upwardly with respective inner surfaces 52', 52" mutually cooperating to define a seat 53 for one or more of the connecting elements 54 of the bandraster 10 to the ceiling C, which may be of a type per se known, and respective outer surfaces 50', 50" defining the support elements for sound-proofed walls PI.

Each of the lower guides 42', 42" may include a base member 420', 420" extending outwardly from the respective outer surface 111', 121' with a first appendix 421', 421" extending upwardly cooperating with the upper guide 4 , 41" to prevent the slippage of the element of mutual connection and a second appendix 170', 170" extending downwardly which cooperates with the outer surface 111', 121' to define the respective seat 17', 17".

On the other hand, each of the upper guides 41', 41" may include a base member 410', 410" extending outwardly from the respective outer surface 111', 121' with a first appendix 41 , 411" extending downwardly cooperating with the lower guide 42', 42" to prevent the slippage of the element of mutual connection and a second appendix extending upwardly defining the shoulder 43', 43".

The above configuration is particularly advantageous, since it allows to exploit to the maximum the outer surface of the bandraster 10. In fact, it is possible in a relatively limited space to stay the wall PI, the bracket for mutually connecting two or more bandrasters and the connecting element 20.

Conveniently, the connecting element 20 may include a support structure 20' with a first portion 21 substantially plane that includes a first end 22 connected or connectable to the panels P and a second portion 23 defining a substantially flat support zone susceptible of coming in contact with the outer surface 16 , 161" of the connection areas 16', 16". Suitably, the substantially flat portions 21, 23 may be substantially parallel. The support structure 20' may include a second end 24 opposite to the first one 21 defining a male element adapted to be inserted in the seats 17', 17", which define female elements.

The support structure 20' may further include a third substantially flat portion 26 interposed between the first two substantially flat portions 22, 23 for connecting the same. Such third substantially flat portion 26, which may be substantially perpendicular to the first two, is susceptible in use to remain facing to the surfaces 111", 121" of the side walls 11, 12 of the bandraster 10.

In a preferred but not exclusive embodiment, the bandraster 10 may externally include a further female element 18', 18" adapted to engage each other by a snap-fitting action a corresponding male element 25 placed on the connection element 20, in particular in correspondence of the third flat portion 26.

It is understood that the male and female elements referred to above may also be reversed without departing from the scope of the appended claims. For example, the connecting element may include the female member and the bandraster the male element, snap-fitting couplable each other.

It is also understood that two snap-fitting elements may be provided at both the upper and lower side without departing from the scope of the appended claims.

It is also understood that the elements referred to above may also be inverted in the position, that is, the male and female elements susceptible to be snap-fitting coupled may be placed above the other, without departing from the scope of the appended claims.

In this way, it is possible to connect the panels P and the bandraster 10 in a simple and fast manner, without the use of screws, bolts or similar fasteners.

In fact, to make the connection it is sufficient to first insert the male element 24 in the female seat 17', 17" and then rotate the connecting element 20 from the top to the down towards the bandraster 10, so that the male member 25 is snap-fitted into the female seat 18', 18".

It is however understood that the above movement depends on the configurations of the male and female elements. Any other movement may be provided without departing from the scope of the appended claims.

Preferably, the female seat 18', 18" may be formed in a protrusion located in correspondence of the female seat 15" inside the compartment 14.

In a further embodiment, the bandraster 10, in particular the connecting areas 16', 16" may externally include further appendices 191', 191", which may be substantially parallel to the portion 23 of the connecting element 20, cooperating with the base member 420', 420" to define the respective seat 17', 17".

The seats 17', 17" may also comprise retaining means 171', 171", for example a series of ribs or a toothed portion, so that the seat 17', 17" defines an engagement seat for the portion 24. In particular, the base member 420', 420" may have a lower portion 422', 422" facing the seat 17', 17" comprising such retaining means 171', 171".

The portion 24 may be deformable so that the same can be rotated around the end

192', 192" of the appendices 191', 191" to be snap-fittingly inserted in the seat 17', 17". In particular, upon the deformation of the end portion 24, the latter is able to interact with the lower portion 422', 422" and then with the coupling means 171', 171" so as to achieve an interlocking to connect the bandraster 10 and the connection element 20.

According to a further aspect of the invention, the bandraster 10 may have further appendices 193', 193" defining a male element, which may have a development substantially orthogonal to the portion 23 of the connecting element 20. On the other hand, the portion 23 may have an appendix 23 , 231" cooperating with the portion 26 to define a seat 232', 232" defining a female element.

To make the connection it is sufficient to first insert the male element 193', 193" in the female seat 232', 232" and then rotate the portion 24 towards the bandraster 10, so as to bring the same portion 24 to engage the lower portion 422', 422" in the seat 17', 17".

Thanks to these features, once connected the connecting element 20 and the bandraster 10, the mutual vertical sliding in both directions may be avoided. In particular, this is achieved in a first direction by the reciprocal interaction of the portion 24 and the portions 422', 422" and in a second direction opposite to the first one by the reciprocal interaction of the female seat 232', 232" and the male element 193', 193".

According to another aspect of the invention, the mutual interaction between the female seat 232', 232" and the male element 193', 193" may prevent the mutual removal between the bandraster 10 and the connecting element 20.

Conveniently, as shown for example in FIGs. 1 and 5b, the connecting element 20 and the supporting bandraster 10 may be configured so that the panel P once in the operating position lie below the edges 1100", 1200", flush with the cover element 30.

In a preferred but not exclusive embodiment, for aesthetic reasons each accessory may include a covering portion, for example the substantially horizontal formation 33 of the cover element 30, configured so that once the false ceiling 1 is in use the supporting bandrasters 10 are completely hidden from the view of a user placed in the space.

This creates a visual continuity for the user, with a unique aesthetic appeal. This configuration is more advantageous than the state of the art systems, and in particular the one of EP2313572. In fact, in the latter case the edges of the bandraster remain on sight, which adversely affects the aesthetic appeal of the assembly.

Moreover, the supporting bandrasters 10 may be rough, unfinished and / or unpainted, while accessories can be finished and / or painted.

This is another important advantage of the present system compared to those of the state of the art, and in particular the one of EP2313572, which allows a saving in terms of time, cost and maintenance. Only the accessories, which are exposed, can be finished and / or painted, while the bandraster may remain rough as it is not at sight.

To allow the complete coverage of the bandraster 10, the maximum width L of the covering portion of the accessories, for example that of the substantially horizontal formation 33 of the cover element 30, may be greater than or equal to the maximum distance D" between the outer surfaces 111", 121".

On the other hand, to cover the protrusion defining the seats 18', 18", the male element 25 may be provided, as shown in FIGs. 3b and 5b, or a lateral appendix 35 of the covering element 30.

In a preferred but not exclusive embodiment, shown for example in FIGs. 4 and 5b, the covering element 30 may include a pair of longitudinal rails 37', 37" for the insertion of one or more elements of connection of two or more covering elements 30. Each longitudinal rail 37', 37" may be defined by respective upper guides 38', 38" and lower guides 39', 39" facing to each other.

Conveniently, the rails 37', 37" can be placed in correspondence of the inner surface 360', 360" of the transverse elements 36', 36".

Thanks to the above configuration, it is possible to connect two or more covering elements 30 in a simple and rapid manner. Suitably, the cover elements 30 connected to each other are incident, for example placed at 90° relative to one another.

This results in an apparent advantage in terms of savings and installation cost.

In fact, where possible instead of joining together the bandrasters 10 by means of the rails 40', 40" it is advantageous to join the cover elements 30 by means of the rails 37', 37".

This may be done where it is not strictly necessary the presence of a supporting bandraster, for example along a corridor or where the bandraster is to be leaved empty and covered by the cover element 30.

Advantageously, in such case the latter may be supported, for example at the ends, by two short portion of a bandraster. The covering element 30, therefore, may have a length L' substantially greater than that L" of the bandraster 10 in which it is inserted.

In case of need, the two portions of the bandraster can then be replaced by a supporting bandraster.

It is clear that the above solution is a considerable saving in economic, maintenance and installation time terms compared to the prior art, for example as taught by the patent US3327438.

To ensure a substantial visual continuity for the user, the panels P and the substantially horizontal formation 33 of the cover element 30 may be configured so as to remain mutually flush and substantially contiguous.

In this way, the user does not perceive the absence of the support bandraster 10 where missing and / or the difference with the parts where the supporting bandraster 10 is present.

It is understood that the cover element 30 can also include only one rail without departing from the scope of the appended claims.

Each of the upper guides 38', 38" and lower guides 39', 39" may be defined by respective upper projections 380', 380" and lower projections 390', 390" extending from the inner surfaces 360', 360" of the transverse members 36', 36".

Suitably, each of the projections 380', 380"; 390', 390" may include a base member 3800', 3800"; 3900', 3900" having a first appendix 3810', 3810"; 3910', 3910" extending respectively downwards and upwards to respectively cooperate with the lower guide 39', 39" and upper guide 38', 38" to prevent the dismounting of the element of mutual connection of two or more covering elements.

FIGS. 8 to 13 show a false ceiling 1 which includes at least one lighting device 31 to light the space S. This embodiment of the false ceiling 1 is particularly suitable to be used in spaces that have to fulfill the known UNI EN 12464-1 such as offices, work stations, shops, warehouses or similar.

More particularly, in the preferred but not exclusive embodiment of the invention shown in the above figures, the narrow zone 14' may have a respective first and second pair of stop elements 150, 150' which can support screw elements 320, 320' of the lighting device 31, as shown in FIG. 1.

The lighting device 31 may include a plurality of LEDs 200 and reflecting means 201 for reflecting the light rays of the LEDs 200 and for leading them towards the space S so as to light the latter.

Suitably, the lighting device 31 may comprise at least one longitudinal support element 310 which may include the screw elements 320, 320'.

The LEDs 200 and/or the reflecting means 201 may be connected with the longitudinal support element 310 so that the lighting device 31 is snap-fitting coupled with the bandraster 10.

Conveniently, the false ceiling 1 may comprise means for feeding the LEDs 200, for example a battery or a cord for connection of the same with an electrical network, not shown in the figures because per se known.

According to a particular aspect of the invention, the reflective means 201 may include at least one reflector element 202 sized so as not to protrude with respect to the of plane π the false ceiling.

As particularly shown in FIG. 8, the latter coincides with the visible surface of the panels P. For example, the panels P may have an upper surface PI facing the ceiling and a lower surface P2 defining the visible surface.

Conveniently, as shown in FIG. 8, the panels P and the reflector element 202 may be flush with each other so as to confer to the assembly a visual continuity and to give the false ceiling 1 a high aesthetic appeal.

Furthermore, the compartment 14 may have a pair of end edges 1100", 1200" opposite with respect to the ceiling C and then facing the space S. Suitably, the reflector element 202 may be configured so as to protrude from the compartment 14 to completely cover the end edges 1100", 1200", so as to conceal the user's view of the bandraster 10.

Thanks to this feature, the bandraster 10 can remain rough and unpainted. This of course leads to reduced costs and working time with respect to the mounting of the false ceiling 1.

In particular, the reflector element 202 may have a generally trapezoidal shape with a central portion 203 located in correspondence with the LEDs 200 and a pair of end portions 204, 204' which are opposite and diverging towards the space S.

These end portions 204, 204' may also include the respective free edges 205, 205' in correspondence of the end edges 1100", 1200" of the compartment 14 to hide the latter, and then the bandraster 10, from the user's view.

According to another aspect of the invention, the LEDs 200 may define an axis X which may lie on a median plane πΜ of the bandraster 10 substantially perpendicular to the plane π. In other words, as particularly shown in FIG. 9, the reflector element 202 may have a longitudinal extension, whereas the LEDs 200 lay in the center thereof.

Conveniently, the latter may be composed of a plurality of reflecting units 210 each of which can be placed in correspondence of a LED 200. In particular, each reflective unit 210 may include a respective central portion 211 and a respective pair of end portions 212, 212'. The latter may be substantially divergent towards the space S.

It is clear that the assembly of individual central portions 211 and the diverging end portions 212, 212' respectively define the central portion 203 and the end portions 204, 204' of the reflecting element 202.

More in particular, the central portion 211 of each reflective unit 210 may include a plurality of step-shaped zones 213 concentric with respect to the corresponding LED 200 and having increasing width towards the space S. In other words, the central portion 211 may substantially diverge towards the space S.

Advantageously, the step zones 213 and the diverging end portions 212, 212' may be suitably dimensioned so as to impart to each reflective unit 210, and to the whole reflector element 202, a predetermined luminous intensity. In other words, by varying the geometry of the reflecting unit 210 it is possible to vary the luminous intensity of the reflector element 202. For practical reasons, the latter may be composed of a plurality of reflective modules 215, each comprising a predetermined number of reflective units 210.

In this way, the installation and any maintenance of the reflecting element 202 is greatly simplified.

Advantageously, the reflective modules 215 may be modular and selectively coupled to each other so as to allow an operator to vary the length of the reflector element 202 in accordance with the number of the same reflective modules 215.

Thanks to this feature, the false ceiling 1 is particularly versatile in that it can be adapted to satisfy the different needs of the space lighting S.

Furthermore, both the production of the reflecting element 202 and the maintenance operations can be fast and cost-effective.

For example, in case there is the need to replace the reflector element 202 for maintenance, thanks to the described above feature it is possible to replace only one or more reflective modules 60 thus facilitating and speeding up maintenance operations.

Furthermore, the mutual removable coupling of the device 31 and the bandraster 10 may allow an operator maintenance and/or replacing operations of the same lighting device 31 without the need to entirely replace the bandraster 10 or the risk of damaging the latter.

According to another aspect of the invention, each reflective unit 210 may include at least one anti-dazzling plate 216, which may be arranged substantially perpendicular to the axis X at the corresponding LED 200.

Furthermore, each reflective unit 210 may provide a pair of side walls 217, 218 disposed substantially parallel to the anti-dazzling plate 216 and cooperating with this to give the lighting device 31 a low dazzling.

Thanks to this particular configuration of the reflecting unit 210, the lighting device 31 may have a UGR dazzling index according to UNI EN 12464-1 lower than or equal to 19.

Furthermore, the anti-dazzling plate 216 may be interposed between the diverging portions 212, 212' of the reflective unit 210 so as to define with the same portions 212, 212' a unitary body, so as to structurally reinforce its reflective unit 210.

In this way, the risk of breaking of the reflecting unit 210 during the handling operations thereof can be avoided, for example upon mounting.

According to a further aspect of the invention, the lighting device 31 may be configured so that the plurality of LEDs 200 and the reflecting means 201 are visible from the outside by the user so as to give the false ceiling 1 an attractive design and an aesthetic appearance particularly pleasant.

In other words, the bandraster 10 may include a closure element for closing the compartment 14 which may be substantially transparent or, preferably, may be free of closure elements, so that between the LEDs 200 and the space S is not interposed any lens.

The use of LEDs in place of the classic neon lights allows to minimize the energy consumption of the lighting device 31, and therefore the spaceal impact thereof.

Referring to figures 14 to 25, a system 100 is described for partitioning a space S, which in a per se known may include a ceiling and a floor. As appropriate, a support wall B or a pair of support walls may be provided.

The system 100 may then allow to partition the space S by at least one partition wall W, preferably a plurality of partition walls W, which can have an upper horizontal edge Wl, a lower horizontal edge W2 and a pair of opposite vertical edges W3, W4.

In fact, these spaces S are partitioned in a different way depending on the needs, for example aesthetic and/or functional need, and often need to be reconfigured.

For this purpose, as better explained hereinafter, the system 100 may allow the removable mounting of the partition wall W. In this way, the operator can easily mount/dismount the partition wall W according to need to configure and/or vary the configuration of the space S.

The system 1 may comprise at least one bandraster 10 to be coupled to the ceiling. In particular, at least one panel P, preferably a plurality of panels P may be provided, coupled with the bandraster 10 so as to form a false ceiling 1. The panels P and the bandraster 10 may be substantially continuous so as to define a substantially horizontal plane nl of the false ceiling 1.

According to an aspect of the invention, the bandraster 10 may be the multifunction bandraster having one or more of the features described above and/or shown in the FIGs. 1 to 13. In particular, the bandraster 10 may have the upper wall 13 facing the ceiling and a lower portion 15 for coupling with the partition wall W, in correspondence of the compartment 14.

On the other hand, the bandraster 10 may be a classic bandraster of substantially quadrangular section, for example made according to the teachings of the documents WO2009/153673 and WO2013/050963.

Suitably, the system 100 may include an accessory 32, shown in particular in FIG. 21A, removably inserted into the compartment 14 for coupling with the partition wall W.

The system 100 may also comprise at least one jamb 220, preferably may be provided with at least one pair of facing jambs 220, 220' arranged on opposite sides with respect to the bandraster 10. In particular, each bandraster 10 may have a first end 101 in correspondence of the respective jamb 220 and a second end 102 opposite to the first one 101 in correspondence with the respective jamb 220'.

In particular, similarly to the bandraster 10, the jambs 220, 220' may include a portion 222 for coupling with the partition wall W in correspondence of the vertical edges W3, W4.

If necessary, the jambs 220, 220' may include a portion 221 comprising at least a compartment 223 for housing one or more accessories, such as cables or lighting devices. In other words, also the jambs 220, 220' may be multifunctional.

As schematically shown in FIG. 23, the jambs 220, 220' may be connected to the support wall B, and in particular may be an integral part thereof. Preferably, the jambs 220, 220' may be connected to the bandraster 10.

The wall B may be substantially continuous to define a plan π2 which can be substantially perpendicular to the plane nl of the false ceiling 1.

This wall B may be made of masonry or plasterboard, or can be a glass wall. In other words, the wall B may be an inner wall or an outer wall without departing from the scope of protection of the present invention.

Preferably, as schematically shown in FIG. 23, the system 100 may include a plurality of bandrasters 10 and a plurality of jambs 220, 220' which may be arranged in the space S so as to allow to partition and reconfigure the same space S according to needs.

Suitably, the bandrasters 10 and jambs 220 may be arranged two by two in correspondence with each other so as to define a support frame 225 for the partition wall W. In case jambs 220' are further provided, as schematically shown in FIG. 23, the support frame 225 may also comprise a jamb 220' faced to the jamb 220.

These frames 225 lie in respective planes π3 substantially perpendicular to the plane πΐ, preferably also perpendicular to the plane π2. In other words, the partition wall W lies in the plane π3 or in a plane substantially parallel to the latter.

Conveniently, each bandraster 10 may include at least one horizontal seat 228 to house the upper edge of the partition wall W while each of the posts 220, 220' may include at least one respective vertical housing 226, 226' for receiving a respective vertical edge of the partition wall W.

Preferably, the horizontal seat 228 may be positioned in correspondence of the lower portion 15 of the bandraster 10 while the vertical housing 226, 226' may be placed at the portion 222 of the jamb 220, 220'.

Suitably, the seats 228, 226, 226' and the corresponding edges Wl, W3, W4 of the wall W may be mutually configured such that the same wall W is removably inserted into the seats 228, 226, 226' to allow the assembly/disassembly of the partition wall W into/from each of the frames 225. Thus, it is possible to vary the configuration of the space S according to need.

In particular, each of the vertical seats 226, 226' may include a pair of first facing lateral walls 2261, 2262 connected by a first bottom wall 2263. Appropriately, a plurality of vertical seats 226, 226' may also be provided.

As particularly shown in FIG. 16B, the vertical seats 226, 226' may include a plurality of longitudinal compartments 224 placed side by side for selectively house the partition wall W. In particular, each of the longitudinal compartments 224 may include a pair of facing lateral walls 2241, 2242 connected by a bottom wall 2243.

Suitably, the side walls 2241, 2242 may be sufficiently spaced to concealably house one of the vertical edges of the partition wall W so that the same remains mutually facing during use with the bottom wall 2243.

In this way, the system 100 may allow the installation of different types of partition walls W. For example, the partition walls W may be of the single-glazed or double-glazed glass walls.

In this way, as shown in FIGs. 15 to 22, the partition walls W mounted on the frames 225 may comprise a single glass sheet (FIGs. 17, 18, 21 and 22) or more sheets of glass (FIGs. 16 and 20).

Possibly, although not shown in the attached figures, gaskets may be provided, preferably made of plastic or elastomeric material, which may be interposed between the side walls 2241, 2242 of the longitudinal compartments 224 and the glass plate of the partition wall W.

In case of partition walls W comprising a glass sheet, once mounted the wall W, the glass sheet can be concealably inserted in the jambs 220, 220' and in the bandraster 10, so as to have a high aesthetic appeal.

According to a particular aspect of the invention, to facilitate the mounting, the horizontal seat 228 of the bandraster 10 may be configured so as to allow a little sliding in the plane π3 of the glass plate of the partition wall W. In this way, the system 100 may also be used if the distances between the floor and the false ceiling 1 slightly vary within the same space S with no need to provide a new frame 225 or modify the same.

According to a further aspect of the invention, the system 100 may include a plurality of longitudinal sealing elements 230 each removably coupled with a respective jamb 220 to conceal from view the respective vertical seat 226, 226'.

In particular, the longitudinal closure element 230 may include a pair of facing lateral walls 2301, 2302 joined by a bottom wall 2303.

Conveniently, as shown in FIG. 14, the side walls 2261, 2262 of the vertical seats 226 may be coupled together with the side walls 2301, 2302 of the longitudinal closure elements 230 so that the respective bottom walls 2263, 2303 remain mutually facing.

In particular, the side walls 2301, 2302 and the sidewalls 2261, 2262 may be mutually snap-fit coupled. For example, in a per se known manner, male-female elements or deformable portions may be provided.

Conveniently, the jambs 220 may be equal to each other so that each of the longitudinal closure elements 230 is insertable in any of jambs 220.

A plurality of longitudinal closing elements 230' may further be provided which can be inserted in the jambs 220' in a manner similar to the closure elements 230. In particular, also the jambs 220' may be equal to each other so that each of the longitudinal closure elements 230' is insertable in any of jambs 220'.

Preferably, the jambs 220 and the posts 220' may be substantially equal to each other so that also the respective longitudinal closing elements 230, 230' are equal to each other. It is understood that in the case of multiple vertical seats 226, 226', the longitudinal closing elements 230, 230' may hide all the vertical seats 226, 226' from the user's view.

According to a further aspect of the invention, the system 100 may further comprise a finishing element 227 removably and selectively coupled with the jambs 220, 220'.

In particular, in case the vertical seats 226, 226' include a plurality of longitudinal compartments 224, the finishing element 227 may be configured such that when the partition wall W engages at least one longitudinal slot 224, the finishing element 227 hides from the user's view the longitudinal compartments 224 not engaged by the partition wall W itself.

In particular, any aspect of the finishing element 227 can include a pair of facing lateral walls 2271, 2272 joined by a bottom wall 2273.

Suitably, the side walls 2241, 2242 of the longitudinal compartments 224 not occupied can be mutually coupled with the side walls 2271, 2272 of the finishing element

227 so that the respective bottom walls 2243, 2273 remain mutually facing.

Possibly, the sidewalls 2271, 2272 of the finishing element 227 and the side walls

2241, 2242 of the longitudinal compartments 224 may be coupled together in a snap fitting manner.

The bandrasters 10 may be similar to the jambs 220, 220'.

In particular, the seats 228 of the horizontal bandrasters 10 may be similar to the seats 226, 226' of the jambs 220, 220' so that the upper edge of the partition wall W is inserted in the seat 228 in the same manner as the side edges of the same wall W are inserted into the respective vertical seats 226, 226'.

In particular, the accessories mentioned above may comprise the longitudinal closure elements or cover 30 substantially similar to the longitudinal closing elements 230, each of which may be removably coupled with a respective bandraster 10 to conceal from view and/or to protect from dirt the respective horizontal seat 228.

On the other hand, in one or more of the bandrasters 10 the lighting device 31 may be inserted.

Suitably, the longitudinal closure element 30 may be configured such that once coupled with the bandraster 10, the same remains substantially flush with the false ceiling 1 so as to define a substantially continuous surface with the latter. In this way, the system 100 and in general the space S can have a high aesthetic appeal.

Furthermore, in the case the horizontal seat 228 includes a plurality of compartments 229 similar to the compartments 224 of the seat 226, the respective longitudinal closing elements 30 may be suitably countershaped with respect to the horizontal seat 228 so as to hide all the rooms 229 to the user's view.

Conveniently, the horizontal seats 228 can removably house alternately and selectively the upper edge of the partition wall W or the longitudinal closure element 230.

In this way, when the partition wall W is not mounted, thanks to the presence of the longitudinal closure elements 230, the space S can have a pleasant appearance. In other words, it is possible to mount/dismount the partition wall W to/from one of the support frames 225 without compromising the structural integrity and preserving the aesthetic appearance of the space S.

Moreover, a finishing element 237 similar to the finishing element 227 may be advantageously provided configured to couple with one or more compartments 229 when the latter are not engaged by the partition wall W.

Preferably, also the finishing element 237 can be coupled in a snap-fitting manner.

For example, FIG. 15 shows a closure element 230 coupled with the jambs 220, 220', FIG. 19 shows a closure element 30 coupled with the bandraster 10, FIGs. 16 to 18 show the finishing elements 227 coupled with the jamb 220, 220', and FIGs. 20 to 22 show the finishing elements 237 coupled with the bandraster 10.

Thanks to these features, even when the partition wall W is mounted, the space S can have a high aesthetic impact.

In particular, FIGs. 24 and 25 show some details of a frame 225 comprising the jamb 220', on which are respectively mounted the longitudinal closure element 230' and the partition wall W.

Eventually, once mounted the longitudinal closure elements 30, 230, 230' or the finishing members 237, 227 respectively on the bandrasters 10 and on the jambs 220, 220', the continuity of the wall B and / or the false ceiling 1 may be interrupted only by the partition wall W.

According to a particular aspect of the invention, the system 100 may further include a guide rail 10', preferably a plurality of guide rails 10', configured and/or dimensioned to be recessed into the floor or coupled with special panels to form a substantially continuous floating floor in a manner similar to that described above for the false ceiling 1.

In particular, the guide rails 10' may be facing to the bandrasters 10, and similarly to the latter may have one end connected with the jamb 220 and an opposite end connected with the jamb 220'.

In other words, the frame 225 may include a pair of opposite jambs 220, 220', a bandraster 10 and a guide rail 10' opposite to the bandraster 10 which can cooperate with each other to house a respective edge of the partition wall W.

Thanks to the above features, the space S may have a pleasing appearance and may maintain its appearance even after the reconfiguration and/or partition of the same space S by mounting / dismounting of one or more partition walls W.

Operationally, at first a plurality of frames 225 may be installed in the space S, then one or more partition walls W may be mounted thereon and finally the longitudinal closure elements 230, 230', 30 may be placed to hide from view the horizontal seats 228 and the vertical ones 226, 226' not engaged by the partition walls W. If necessary, it is also possible to mount the finishing elements 227, 237 to hide from view compartments 229 and 224 not engaged by the edges of the partition walls W.

In case of need of reconfiguration of the space S, it is sufficient to remove the partition walls W, and, if present, the finishing elements 227, 237, and appropriately place the longitudinal closure elements 230, 230', 30 on the frames 225. Moreover, it is also possible to remove the longitudinal closure elements 230, 230', 30 and mount to the partition walls W on the frames 225. If necessary, it is also possible to mount the finishing elements 227, 237 to cover the compartments 229 and 224 not engaged by the edges of the partition walls W, to confer to the space S a high aesthetic appeal.

Referring to Figures 26 to 31, a glass door 300 is described which may be particularly suited to be inserted in a partition structure 304 for partitioning a space with high aesthetic impact.

In a non-limiting example, the partition structure may include the partition wall W shown in figures 14 to 25. More generally, the at least one partition wall W of the system 100 may include the glass door 300.

In particular, the partition structure 304 may include at least one panel or a glass wall 305 which may be substantially planar. On the other hand, the glass door 300 may have an outer surface 302 which is also substantially planar.

In this way, when the door 300 is closed, the outer surface 302 of the latter and the glass wall 305 may define an outer surface 306 substantially continuous in view of the partition structure 304.

In particular, the door 300 may include a support frame 311 and at least one glass plate 321 that may define a plane π substantially coincident with the plane of the outer surface 302. The frame 311 and the plate 321 may be coupled to each other, preferably glued.

In order to improve the aesthetic appearance of the door 300, the support frame 311 and the glass plate 321 may be coupled so that the former does not protrude with respect to the latter.

In particular, the support frame 311 may be disposed peripherally with respect to the glass plate 321 so that the peripheral edges 312 of the frame 311 and the peripheral edges 322 of the plate 321 remain substantially flush, as shown in FIG. 28.

Therefore, once the door 300 is closed, at least one end portion 303 thereof, namely the one comprising the peripheral edges 312, 322, is conveniently faced to a corresponding end 307 of the wall 305 and is flush therewith, as particularly shown in FIG. 29.

According to an aspect of the invention, the plate 321 may have two planar surfaces substantially opposite to each other. In particular, the latter may define the two opposite faces 324, 324' of the plate 321.

For example, once the door 300 is closed, the face 324' of the sheet 321 may define the outer exposed surface 302 of the door 1, while the other face 324 of the plate 321 may be coupled with the support frame 311.

The latter may be substantially tubular, and may preferably be an extruded metallic material, for example aluminum.

In addition, the support frame 311 may have a low predetermined width LA so that the overall dimensions and the visual impact of the same are minimized. For example, the support frame 311 may have a width LA less than 50 mm, and preferably less than 40 mm, for example about 35 mm.

Thanks to the above features, the visual impact of the tubular frame 311 on the door 300 will be minimal. In other words, the non-transparent surface of the door 300 will be minimal, so as to give the same door 300 an attractive design.

The door 300 may also include closing means 330 of a known type, which may include at least one movable closing element 331, for example a latch, susceptible to interact with a corresponding fixed closing element 335, for example, a seat of the latch, coupled with the wall 305.

On the other hand, the support frame 311 may include a portion 31 in correspondence with the seat 335 suitable for housing the movable closing element 331 so that the latter can remain hidden for the user's view.

In a per se known way, the movable closing element 331 may be movable between a working position in which the element interacts with the fixed closing element 335 to prevent opening of the door 300 and a rest position in which it does not interact with the fixed closing element 335 to allow opening of the door 300.

The door 300 may further include actuating means 340, which act on the movable cover 331 to promote the movement between the work and the rest positions.

In particular, the user can act on these actuator means 340 to promote the movement of the movable closing element 331 from the working position to the rest position, so that the user can open the door 300.

Conveniently, the actuator means 340 may further comprise a counteracting spring, not represented in the figures because per se known, acting on the movable cover 331 to push it back from the rest position to the working position.

The actuator means 340 may also include at least a portion 342 operable by a user, for example a handle or a portion thereof, to allow the user to operate to the same actuator means 340.

Furthermore, the actuator means 340 may include a spindle 341, which may be operatively coupled with the handle 342. In particular, the latter may include a coupling portion 343 that may be countershaped with respect to the spindle 341 and first fixing means, for example at least one first stop screw not shown in the figures as per se known, acting on the same spindle 341 so as to allow the integral coupling of the handle 342 and the spindle 341.

According to a particular aspect of the invention, the spindle 341 may pass through the frame 311 so as to interact with the movable closing element 331 to actuate the latter, for example by means of a cam and follower mechanism.

To do this, the support frame 311 may comprise a passing-through opening 313 defining an axis X substantially transversal with respect to the plane π for the insertion of the spindle 341.

According to an aspect of the invention, the handle 342 may be placed on the side of the door 300 in correspondence with the glass plate 321. In this case, also the plate 321 may suitably comprise a through opening 325 substantially coaxial with the through opening 313 of the frame 311 so as to allow the insertion of the spindle 341 through the plate 321 and the frame 319.

Suitably, the door 300 may include at least one first washer 350 susceptible to remain interposed between the handle 342 and the glass plate 321 so that the former does not come into contact with the latter. In particular, the washer 350 may have a first portion 351 susceptible to be facing to the handle 342 and an opposite portion 352 susceptible to remain facing to the glass sheet 321.

Thanks to this feature, it is possible to avoid that the actuator means 340, and in particular the spindle 341, come into contact with the glass sheet 321 while avoiding that the latter is damaged because of the movements of the handle 342.

Suitably, the door 300 may have at least one annular seat 326 for the washer 350 substantially coaxial to the passing-through opening 325 of the glass sheet 321, and in particular for the portion 352 of the same washer 350.

In particular, the annular seat 326 may have a bottom wall 327 susceptible to act as a stop for the washer 350 and a side wall 328 susceptible to contain the same washer 350 to prevent it from sliding along the plane π.

Therefore, the portion 352 of the washer 350 is substantially countershaped relative to the annular seat 326, so as to remain stably coupled therewith and ensure the centering of the handle 342.

More in detail, also the washer 350 may be substantially coaxial to the opening 313 of the frame 311 and/or to the opening 325 of the plate 321. In this way, the washer 350 itself may act as a guide for the handle 342 and/or for the spindle 341 so that the latter remain substantially coaxial to the openings 313, 325. According to a further aspect of the invention, the annular seat 326 can be manufactured within the thickness T of the glass sheet 321, for example by means of a drilling operation, in correspondence of the passing-through opening 325, which may be for example a substantially circular passing-through hole.

In particular, the distance Dl between the bottom wall 327 of the annular seat 326 and one of the outer surfaces 324, 324' opposite to the plate 321 may be less than the thickness T of the latter. For example, for a plate having thickness T of about 6 mm this distance Dl may be about 3 mm.

Furthermore, the annular seat 326 may have a diameter d2 substantially greater than the diameter dl of the passing-through hole 325.

For example, for a plate having thickness T of about 6 mm, the passing-through hole 325 may have a diameter dl of 12 mm to 25 mm, preferably about 15 mm, while the annular seat 326 may have a diameter d2 of 15 mm to 35 mm, preferably about 23 mm.

The passing-through hole 325 of the glass sheet 321 can be performed in the vicinity of the edge 322 of the glass sheet 321. In particular, the center of the passing-through hole 325 may have a distance D2 from edge 322 of the plate 321 less than the width LA of the frame 311, preferably a distance D2 less than 30mm, more preferably of about 16,5 mm.

According to a further aspect of the invention, the door 300 may include at least one first annular seal 360 which may be interposed between the bottom wall 327 of the annular seat 326 and the washer 350 to mutually lock the former and the latter. In this way, the seal 360 may remain completely hidden to the user's view.

In order to improve the aesthetic appearance of the door 300, the latter may include a rosette 370 coaxial to the passing-through opening 325 so as to hide the annular seat 326 to the user's view.

In particular, the rosette 370 may be configured so that once inserted in the annular seat 326, the rosette 370 come in abutment against the plate 321.

Suitably, the rosette 370 may have an outside diameter d3 substantially greater than the diameter d2 of the annular seat 326 and less than the width LA of the support frame 311.
