Definitions

  • the present invention relates to a glass panel comprising a connecting flange which realises a fixing system between the panel and a support.
  • the glass panel according to the present invention enables obviating these drawbacks due to inner stresses in the material of the panel; these stresses arise due to the constraining action of the forces applied by the connecting means to which the action of fixing the glass panel to the support is devolved.
  • the invention is particularly useful in the sector of layered glass panels and even more in particular - but not exclusively - in the sector of manufactured products comprising the connection of glass panels on other supporting elements, also made of glass.
  • layered glass panel is used to denote a panel realised by joining two or more layers of glass, alternated with a sheet made of a plastic material.
  • the structure thus obtained is heated, pressed and subjected to treatment in an autoclave at variable temperatures and pressures so as to expel the air between the layers and enable adhesion and bonding of the entire panel.
  • fixing a glass panel 100 to a surface 3a of a vertical supporting element 3, which could also be made of glass is obtained by the use of a plate 400 - typically a metal plate - interposed between the layers 100a, 100b, 100c of the glass panel 100 to be fixed; generally, the plate is positioned in replacement of a portion of edge of the central glass pane 100c, that is, the one substantially in the middle of the panel 100. Therefore, the central layer 100c is, in the perpendicular direction to the surface 3a of the supporting element 3 to which the panel will fixed, shorter than the others.
  • the panel 100 is equipped with a lateral bordering surface 200 designed to abut against the surface 3a of the support 3, in such a way that the plate 400 can be constrained to the supporting element 3 by connecting means 5 such as screws or the like; in more detail, the connecting means 5 are inserted on the opposite side of the surface 3a of the support 3 on which the panel will go in abutment.
  • the plate is configured so as to receive them.
  • the plate is in turn joined to the panel, in particular to the layers of the panel in the case of a multi-layer panel, so that the panel remains in equilibrium.
  • the plate 400 exhibits a longitudinal portion 400c fixed to the panel and positioned parallel to base surfaces S', S" of the panel itself.
  • the above-mentioned plate 400 that replaces a portion of the edge of the panel - or a layer of the panel - is often not inserted snugly in the panel itself; in particular, owing to tolerances or manufacturing defects, the edge of the plate is not squared with the lateral bordering surface 200 of the panel, but is slightly recessed relative thereto.
  • the edge of the plate is not squared with the lateral bordering surface 200 of the panel, but is slightly recessed relative thereto.
  • this drawback may occur even if the edge of the plate is squared or projects relatively to the lateral bordering surface 200 of the panel.
  • this force determines a flexion of the support 3 which generates a pair of opposite forces, precisely traction and compression, acting respectively on the plate and on a part of the lateral bordering surface 200 of the panel (for example, on the lower layer 100b of the panel 100 of figure 1), depending on the straight line of application of the transversal force with respect to the plate.
  • the pair of forces disadvantageously determines a relative sliding between the plate and the layer of glass adjacent to it (above and/or below the plate itself, depending on the application line of the transversal force).
  • a membrane G made of a deformable material can further be placed between the lateral bordering surface 200 of the panel and the surface 3a of the support 3, which membrane G is necessary for preventing - or reducing - infiltration of dirt and moisture and suitable for damping the stresses between the panel and the support.
  • the seal is made of a deformable material, it can be subject to different crushing forces at the plate and of the layers adjacent to the plate, following the action exerted on the plate by of the connecting means.
  • the plate is squared with the lateral bordering surface 200 of the panel, it is very possible that the action exerted by the connecting means can cause relative sliding between the plate and the portion of panel (or the layer, in the case of multi-layer panels) just above and/or just below the plate itself; further, the action exerted by the connecting means may cause a distancing of the plate from the central layer at which the plate is located.
  • the presence of the membrane in deformable material may cause different movements of the layers of the panel and of the plate in the direction which is substantially perpendicular to the surface of the support to which the panel is to be fixed.
  • a non-squared alignment between the edge of the plate and the lateral bordering surface 200 of the panel or the load exerted by force transversal to the support or, the action of the connecting means can be the cause of relative sliding between the plate and the glass bordering it.
  • These relative sliding actions can disadvantageously easily lead to detachments between glass layers adjacent to and/or between the glass layers and the plate and/or between the plate and the panel in its entirety (in the case of panels that are not multi-layer panels), creating undesired air bubbles which, as well as generating aesthetic flaws, determine a deterioration of the adhesion between the glass and the plate, leading to significant problems of mechanical strength and of wear.
  • the aim of this invention is to disclose a glass panel integrated with a fixing system comprising a connecting flange which prevents, or reduces, infiltration of dirt and moisture, which simultaneously obstructs and possibly eliminates occurrence of detachment, adhesive failure and/or relative sliding between the layers of the panel and/or between the panels and the connecting flange and/or between the plate and the panel in its entirety (in the case of panels that are not multi-layer).
  • a further aim of the invention is to provide a glass panel integrated with a fixing system comprising a connecting flange able to obstruct - and possibly eliminate - the occurrence of detachment, failure of adhesion and/or relative sliding between the glass and the flange, even in the presence of loads exerted by transversal forces to the support and/or in the presence of glass panels that are not squared.

  • the dependent claims correspond to further embodiments of a method according to this invention.

Description

GLASS PANEL WITH CONNECTION TO A SUPPORTING ELEMENT
DESCRIPTION
Technical field
The present invention relates to a glass panel comprising a connecting flange which realises a fixing system between the panel and a support. The glass panel according to the present invention enables obviating these drawbacks due to inner stresses in the material of the panel; these stresses arise due to the constraining action of the forces applied by the connecting means to which the action of fixing the glass panel to the support is devolved.
The invention is particularly useful in the sector of layered glass panels and even more in particular - but not exclusively - in the sector of manufactured products comprising the connection of glass panels on other supporting elements, also made of glass.
The term "layered glass panel" is used to denote a panel realised by joining two or more layers of glass, alternated with a sheet made of a plastic material. The structure thus obtained is heated, pressed and subjected to treatment in an autoclave at variable temperatures and pressures so as to expel the air between the layers and enable adhesion and bonding of the entire panel.
Background art
According to the prior art and illustrated purely by way of example in figure 1 , fixing a glass panel 100 to a surface 3a of a vertical supporting element 3, which could also be made of glass, is obtained by the use of a plate 400 - typically a metal plate - interposed between the layers 100a, 100b, 100c of the glass panel 100 to be fixed; generally, the plate is positioned in replacement of a portion of edge of the central glass pane 100c, that is, the one substantially in the middle of the panel 100. Therefore, the central layer 100c is, in the perpendicular direction to the surface 3a of the supporting element 3 to which the panel will fixed, shorter than the others. The panel 100 is equipped with a lateral bordering surface 200 designed to abut against the surface 3a of the support 3, in such a way that the plate 400 can be constrained to the supporting element 3 by connecting means 5 such as screws or the like; in more detail, the connecting means 5 are inserted on the opposite side of the surface 3a of the support 3 on which the panel will go in abutment.
These connecting means are inserted in the plate, which is configured so as to receive them. The plate is in turn joined to the panel, in particular to the layers of the panel in the case of a multi-layer panel, so that the panel remains in equilibrium. In particular, the plate 400 exhibits a longitudinal portion 400c fixed to the panel and positioned parallel to base surfaces S', S" of the panel itself.
The above-mentioned plate 400 that replaces a portion of the edge of the panel - or a layer of the panel - is often not inserted snugly in the panel itself; in particular, owing to tolerances or manufacturing defects, the edge of the plate is not squared with the lateral bordering surface 200 of the panel, but is slightly recessed relative thereto. In this case, after it has been subjected to the action exerted on the plate by of the connecting means, there is a disadvantageous relative sliding between the plate and the portion of panel (or the layer, in the case of multi-layer panels) just above and/or just below the plate itself. Even more disadvantageously, this drawback may occur even if the edge of the plate is squared or projects relatively to the lateral bordering surface 200 of the panel. In effect, in the case where the support 3 is loaded with a transversal force substantially parallel to the base surfaces S, "S," this force determines a flexion of the support 3 which generates a pair of opposite forces, precisely traction and compression, acting respectively on the plate and on a part of the lateral bordering surface 200 of the panel (for example, on the lower layer 100b of the panel 100 of figure 1), depending on the straight line of application of the transversal force with respect to the plate. The pair of forces disadvantageously determines a relative sliding between the plate and the layer of glass adjacent to it (above and/or below the plate itself, depending on the application line of the transversal force). In the prior art, a membrane G made of a deformable material can further be placed between the lateral bordering surface 200 of the panel and the surface 3a of the support 3, which membrane G is necessary for preventing - or reducing - infiltration of dirt and moisture and suitable for damping the stresses between the panel and the support.
Since the seal is made of a deformable material, it can be subject to different crushing forces at the plate and of the layers adjacent to the plate, following the action exerted on the plate by of the connecting means. In this case, too, though the plate is squared with the lateral bordering surface 200 of the panel, it is very possible that the action exerted by the connecting means can cause relative sliding between the plate and the portion of panel (or the layer, in the case of multi-layer panels) just above and/or just below the plate itself; further, the action exerted by the connecting means may cause a distancing of the plate from the central layer at which the plate is located. In still other terms, the presence of the membrane in deformable material may cause different movements of the layers of the panel and of the plate in the direction which is substantially perpendicular to the surface of the support to which the panel is to be fixed.
To sum up, a non-squared alignment between the edge of the plate and the lateral bordering surface 200 of the panel or the load exerted by force transversal to the support or, the action of the connecting means can be the cause of relative sliding between the plate and the glass bordering it. These relative sliding actions can disadvantageously easily lead to detachments between glass layers adjacent to and/or between the glass layers and the plate and/or between the plate and the panel in its entirety (in the case of panels that are not multi-layer panels), creating undesired air bubbles which, as well as generating aesthetic flaws, determine a deterioration of the adhesion between the glass and the plate, leading to significant problems of mechanical strength and of wear. Aim of the invention
The aim of this invention is to disclose a glass panel integrated with a fixing system comprising a connecting flange which prevents, or reduces, infiltration of dirt and moisture, which simultaneously obstructs and possibly eliminates occurrence of detachment, adhesive failure and/or relative sliding between the layers of the panel and/or between the panels and the connecting flange and/or between the plate and the panel in its entirety (in the case of panels that are not multi-layer).
A further aim of the invention is to provide a glass panel integrated with a fixing system comprising a connecting flange able to obstruct - and possibly eliminate - the occurrence of detachment, failure of adhesion and/or relative sliding between the glass and the flange, even in the presence of loads exerted by transversal forces to the support and/or in the presence of glass panels that are not squared. Brief description of the drawings
The set technical purpose and the specified aims are substantially attained by a glass panel comprising the technical characteristics described in one or more of the appended claims. The dependent claims correspond to further embodiments of a method according to this invention.

The connecting flange comprises a transversal extension positioned transversally relative to the longitudinal portion so as to cover a part of the lateral bordering surface facing the support, so as to abut against a supporting surface of the supporting element. More in detail, the transversal extension opposes and adheres to the part of the lateral bordering surface facing the support, in such a way as to form an abutment designed to abut against the surface of the supporting element.
In this way the abutting zone between the connecting flange and the supporting element extends about the constraining point of the connecting means.

In this way, the extension of the contact zone between the connecting flange and the constraining element around the constraining point of the connecting means is optimised.
The first portion and the second portion of the transversal extension are preferably facing opposite sides with respect to the longitudinal portion. The longitudinal portion is preferably positioned in an intermediate position with respect to a thickness of the panel.
The panel preferably comprises a plurality of layers made of one or more vitreous materials.

Detailed description of preferred embodiments of the invention
With reference to figure 2, reference numeral 1 indicates a glass panel according to a first embodiment of the invention, which comprises a base surface S', for example larger, and, a base surface S", for example smaller, delimited by a lateral bordering surface 2.
The lateral bordering surface 2 is suitable for being constrained to a supporting element 3, in particular by abutting against a supporting surface 3a. In a possible variant, the supporting element 3 may also be made of glass.
The glass panel 1 comprises a connecting flange 4 suitable for receiving connecting means 5 to the supporting element 3. According to a possible embodiment, the connecting flange 4 comprises a first transversal extension 4a, a second transversal extension 4b and a longitudinal portion 4c. At least the longitudinal portion 4c is fixed to the panel and positioned transversally relative to the lateral bordering surface 2.
The first transversal extension 4a is positioned transversally with respect to the longitudinal portion 4c in such a way as to cover a first part, or first edge, 2a of the lateral bordering surface 2 of the panel 1 and abut against the supporting surface 3a. In more detail, the first transversal extension 4a of the connecting flange 4 contrasts and adheres to the first part, or first edge 2a, of the lateral bordering surface 2 of the panel 1.
The second transversal extension 4b is positioned transversally with respect to the longitudinal portion 4c in such a way as to cover a second part, or second edge, 2b of the lateral bordering surface 2 of the panel 1 , and abut against the supporting surface 3a. In more detail, the second transversal extension 4b of the connecting flange 4 contrasts and adheres to the second part, or second edge 2b, of the lateral bordering surface 2 of the panel 1.
The longitudinal portion 4c is at least partly inserted in a seat 6 made in the glass panel 1 , preferably positioned between the surface of the upper base S" and the surface of the lower base S". The inserting of the longitudinal portion 4c in the seat 6 of the panel 1 optimises the function of supporting the glass panel 1 by the connecting flange 4.
In the embodiment shown in figure 2, the first transversal extension 4a and the second transversal extension 4b face opposite sides in relation to the longitudinal portion 4c. The longitudinal portion 4c is preferably positioned in an intermediate position with respect to a thickness of the panel 1 , for example for convenience of the assembly operations.
According to a further aspect of the invention, the connecting flange 4 is fixed internally of the seat 6 by a bonding material, such as a plastic material, for example PVB (polyvinyl butyral), EVA (ethylene acetate) or an ionoplastic material. The bonding material is preferably also positioned "at the head", i.e. is interposed between the edges 2a, 2b of the lateral bordering surface 2 of the panel which edges 2a, 2b oppose respective transversal extensions 4a, 4b. This technical solution advantageously gives the panel a considerable tensile strength along a direction parallel to the base surfaces S', S". In addition, the technical solution reduces, almost eliminating, the formation of air bubbles in the joining zone between the connecting flange 4 and the panel, typically inside the seat 6.
In essence, the transversal extensions 4a, 4b cooperate to form an abutment able to adhere against the lateral edges 2a, 2b of the bordering surface 2 of the panel 1 , the abutment being simultaneously destined to contact against the supporting surface 3a of the supporting element 3. A situation in which the invention is very efficient is that the panel 1 comprises a plurality of glass layers, for example a first outer layer 1 a, a second outer layer 1 b and possibly an intermediate layer 1 c. In the case of a plurality of glass layers, the longitudinal portion 4c is at least partly inserted, for example, between the outer layers 1a and 1 b of the panel 1. More specifically, in the case of two outer layers 1 a, 1 b and an intermediate layer 1 c, the intermediate layer 1 c is shorter along a perpendicular direction to the lateral bordering surface 2, so as to define the seat 6 in which the longitudinal portion 4c is at least partly inserted. For reasons of structural symmetry, the longitudinal portion 4c is also substantially parallel to the layers 1a, 1 b and 1c of the panel 1 .
In the embodiment illustrated in figure 2, the first transversal extension 4a of the connecting flange 4 contrasts and adheres to a lateral edge 2a of the first outer layer 1 a of the panel .
In the embodiment illustrated in figure 2, the second transversal extension 4b of the connecting flange 4 contrasts a lateral edge 2b of the second outer layer 1 b of the panel 1 .
In essence, in the embodiment illustrated in figure 2, the transversal extensions 4a, 4b act in conjunction to form an abutment suitable for adhering against the lateral edges 2a, 2b of the outer layers 1 a, 1 b of the panel 1 , the abutment being simultaneously able to abut against the supporting surface 3a of the supporting element 3.
In accordance with the embodiment shown in figure 6, the panel 1 comprises two layers of glass 1 a, 1 b each having a recessed undercut such that when the layers of glass 1 a, 1 b have been coupled to one another a seat 6 is defined for insertion of the longitudinal portion 4c of the flange 4. For reasons of structural symmetry, the longitudinal portion 4c is substantially parallel to the layers 1a, 1b of the panel 1. Again with reference to figure 6, the first transversal extension 4a of the connecting flange 4 contrasts a lateral edge 2a of the first layer 1 a of the panel 1 , while, the second transversal extension 4b of the connecting flange 4 contrasts a lateral edge 2b of the second layer 1b of the panel 1. In this variant embodiment too, the transversal extensions 4a, 4b act in conjunction to form an abutment suitable for adhering against the lateral edges 2a, 2b of the outer layers 1a, 1b of the panel 1 , the abutment being simultaneously able to abut against the supporting surface 3a of the supporting element 3.
A connecting flange 4 according to the invention advantageously makes it possible to pack the glass layers of the panel and defines a single element with respect to which all the layers of the panel are solidly constrained to one another. In this way, the forces generated by the constraining action of the connecting means 5 are absorbed solely by the plate, thus preventing non-uniform distribution of the forces on the individual glass layers of the panel. Therefore, any relative sliding between the layers of glass is advantageously, eliminated. Note that the invention still more advantageously prevents relative sliding between the plate and the layers of glass just above and/or just below the plate itself, even in the presence of a transversal load exerted by a force transversal to the support 3 and substantially parallel to the base surfaces S', S".
Further, a connecting flange according to the invention makes it advantageously possible to radically obviate the problem of non-squared alignment between the lateral bordering surface of the panel and the flange; in effect, the transversal extensions in cooperation with the longitudinal portion define a contact surface that compensates for any misalignments between the individual layers of the panel.
In accordance with the embodiments illustrated by way of example, a seal G can be interposed between the connecting flange 4 and the supporting surface 3a. Advantageously, in a way clearly different to the prior art, the fastening of the connecting means 5 does not cause different deformations of the seal G; owing to the presence of the first transversal extension 4a and the second transversal extension 4b, there is no relative sliding between the connecting flange 4 and the layers of glass bordering the flange, thus obviating the drawbacks of the system of the prior art. It should be noted that the present invention is particularly and significantly useful even in the absence of the seal G, for example if the surface 3a of the mounting element 3 is not flat or presents an irregular geometric conformation, such as to determine - in a case of use of the panels according to the prior art - a different action of the connecting means on the various layers of the panel.
In the preferred embodiment of this invention, the layers of the panel t are made of one or more vitreous materials.
At least one bonding material is advantageously interposed between the layers of glass 1a-1c, such as a plastic material, for example PVB (polyvinyl butyral) or EVA (ethylene acetate) to obtain a panel made of layered glass. In a further variant embodiment, an ionoplastic material can advantageously be interposed between the layers of glass 1a to 1c. Use of the plastic material increases the resistance of the panel and improves acoustic insulation. It is further very useful for glass stairs and for parapets, since it considerably reduces the risk of a breakage of the panel by fragmentation of the glass into large pieces and/or potentially very hazardous sharp shards. The plastic material advantageously, also gives the glass anti-breakage characteristics. In accordance with a further variant embodiment, a finishing appearance material, such as, for example, wood, marble, etc., can advantageously be interposed between the layers of glass 1a to 1c.
The assembling of the glass layers is done using an in-line or vacuum method for type, or with a method of another type. According to a further aspect of the invention shown, for example, in figure 7, the bonding material is positioned also "at the head", that is to say, is interposed between the edges 2a, 2b of the layers of the panel 1 which contrast respective transversal extensions 4a, 4b of the connecting flange 4. In figure 7, the glue positioned "at the head" is denoted by reference numerals 44a, 44b. This technical solution - together with the presence of the adhesive 44c also in the seat 6 - advantageously gives the panel a considerable tensile strength along a direction parallel to the layers of glass. In addition, the technical solution reduces, up to almost eliminating, the formation of air bubbles in the joining zone between the connecting flange 4 and the layers of the panel, typically inside the seat 6.
In the case of presence of one or more materials interposed between the layers of glass, the thickness of any vitreous layer of the panel 1 may be, simply by way of example, approximately 10 mm, and the distance between two adjacent layers comprised between approximately 0.35 mm and approximately 5 mm.
To increase the supporting capacity of the connecting flange 4, especially if the support 3 is vertical, the flange 4 is made of a metal material, or a metal alloy or is made of composite materials or, possibly of polycarbonate or the like. Use of the polycarbonate advantageously makes the plate transparent and therefore not visible.
Figure 4 is a perspective view of the embodiment of this invention shown in figure 2, wherein the supporting element 3 is sectioned, so that the connecting means 5 are visible, for example embodied by a screw that inserts in the longitudinal portion 4c of the connecting flange 4. The latter, in this case, also comprises the transversal extensions 4a, 4b which are, in contrast, respectively, to the first outer layer 1 a and to the second outer layer 1 b of the glass panel 1 . The longitudinal portion 4c is aligned with the with the intermediate layer 1c of the panel 1 , also sectioned.
The first and second transversal extension 4a, 4b of the connecting flange 4 are in abutment with the supporting surface 3a of the supporting element 3, preferably via an interposed seal not shown in figure 4 for reasons of clarity.
The longitudinal portion 4c and at least one of the transversal extensions 4a and 4b are preferably made in a single piece. In figure 2 and figure 4, both the longitudinal portion 4c and the first and second transversal extension 4a and 4b are made in a single piece.
Alternatively, the longitudinal portion 4c and at least one of the transversal extensions 4a and 4b are structurally separate and are connected to form the connecting flange 4. The first and second transversal extension 4a and 4b are preferably made in a single body connected to the longitudinal portion 4c. In a possible embodiment, not illustrated, the first and second transversal extension 4a and 4b are connected by welding to the longitudinal portion 4c.
As a further alternative, in a second possible embodiment shown in figure 3, the longitudinal portion 4c' and at least one of the transversal extensions 4a', 4b' are designed to be connected by the connecting means 5 in the assembled configuration of the panel 1 ' and the supporting element 3. In this second embodiment, it can be observed that the longitudinal portion 4c', inserted in the cavity 6 of the panel 1', is now distinct with respect to the transversal extensions 4a', 4b' which abut against the supporting surface 3a, preferably by interposing of the interposed seal G.
The longitudinal portion 4c' is advantageously connected to a single body which comprises the first and the second transversal extension 4a', 4b' via a connecting means 5 also suitable for fixing the panel 1 to the supporting element 3. The first transversal extension 4a' contrasts an edge of the first external layer 1a' of the panel Γ, while, the second transversal extension 4b' contrasts a lateral edge 1b of the panel 1'. In this case, too, the longitudinal portion 4c' is preferably aligned with an intermediate layer 1c' of the panel 1'.
This second embodiment reduces storage costs, since it allows a better flexibility in the geometry of connecting flange 4'.
A further embodiment of the connecting flange 4" might have, as shown in figure 5, only a first transversal extension 4a". This further type of connecting flange 4" can therefore be used in a further possible realisation of the invention. In this case, too, the longitudinal portion 4c" and the first transversal extension 4a" can be made of a single body as illustrated in figure 5 or can be structurally separate and are connected to form the connecting flange. In a possible embodiment, not illustrated, the first transversal extension is connected by welding to the longitudinal portion. As a further alternative, the longitudinal portion and the first transversal extension are suitable for connecting by the connecting means in the assembled configuration of the panel and of the supporting element.
According to the invention, all the variant embodiments described include the possibility that the portions of the glass panel at which the connecting flange is positioned are treated with a non-transparent covering material, for example a film or a paint. The treatment advantageously hides the presence of air micro-bubbles which can be formed during the processing of the glass or following the mechanical stresses applied during the working life of the product. Any painting is preferably performed by silk screening or during the hardening operation of the glass using paints, for example of the ceramising type.
Variations and combinations of the described characteristics are possible, without thereby departing from the scope of protection of the claims.
