Definitions

  • the present invention relates to a window, of the openable or fixed type.
  • Document DE 203 13 884 U1 discloses a window according to the preamble of claim 1.
  • the aim of the present invention is to produce a window that allows to fulfil the above requirement in a simple and inexpensive way.
  • a window is provided, as defined in claim 1.
  • the sections that form the perimeter frame have foamed material provided with still air cells.
  • the sections of the new window systems, according to the present invention are produced with specific moulds, thanks to which reinforcement elements, hinges, outer finishing shells, etc. can be embedded in the foamed material.
  • These sections which are mounted as "glass enclosing" sections in the workshop, they perform not so much a function of structural elements (left to the double-glazed unit inside the perimeter frame), but an insulating function and a function of filling joints in the gaps between the double-glazed unit and the moving and closing hardware.
  • the stiffness of the double-glazed unit (and not that of the foamed sections) as a load-bearing element is advantageously used: in other words, it is as if the window moves without any perimeter frame, given the function of mere filling of the empty gaps assigned to the sections.
  • the reference number 1 denotes a window comprising an outer framework 2, connected in a fixed position to a building support structure, for example to a wall 3 ( Figure 2 ); and a leaf 4, which engages an opening 5 defined by the framework 2 and is coupled in a movable manner to the framework 2 to open and close said opening 5.
  • the leaf 4 is coupled to the framework 2 by means of hinges, not illustrated, so as to rotate around a vertical axis along an upright of the framework 2.
  • the present invention also applies to fixed, non-openable, windows and to windows in which the opening technique is different from the one mentioned above by way of example (e.g. bottomhinged windows).
  • the leaf 4 comprises a frame 10 formed by framework elements arranged in series and defined by two vertical uprights 11 and by two horizontal crosspieces 12.
  • the ends 13 of the crosspieces 12 are fixed to the ends 14 of the uprights 11 in a known manner, not described in detail, so as to form a quadrangular perimeter and define an opening 15 inside the frame 10.
  • the leaf 4 comprises, furthermore, a transparent (or semi-transparent) panel, denoted by the reference number 16, which permanently closes the opening 15 and comprises at least two sheets of glass.
  • a transparent (or semi-transparent) panel denoted by the reference number 16
  • the glass could be replaced by a different transparent material, for example by PMMA (sometimes also referred to as "acrylic glass").
  • the panel 16 comprises two sheets 17 and 18, which are defined for example by a multilayer glass, and are parallel and spaced so as to form an air space or gap 20 between one another, whereby the panel 16 defines a so-called "double-glazed unit” or "double-glass".
  • the air space 20 is isolated from the outer environment by means of a spacer element 21 arranged between the sheets 17 and 18 along a perimetral edge portion 22 of the panel 16. At the portion 22, the sheets 17 and 18 are delimited by:
  • the face 23 is facing, in use, towards the outside of the building in which the window 1 is mounted, while the face 24 is facing towards an internal environment of said building.
  • Figure 2 shows the cross-section of one of the crosspieces 12, but the same characteristics can also be applied to the other crosspiece 12 and/or to the uprights 11.
  • the crosspiece 12 comprises at least one section element 31, which extends along a direction 32, orthogonal to the plane of the section of Figure 2 , preferably along the entire length of the crosspiece 12, that is, from one end 13 to the other.
  • the crosspiece 12 has a seat 33, which is parallel to the direction 32, is engaged by the portion 22 of the panel 16 and is defined by:
  • the seat 33 has a U-shape, and the surfaces 38 and 39 form a jaw in which the portion 22 is held.
  • the section element 31 comprises a foamed polymer material, formed in one piece.
  • said material is defined by foamed polystyrene, also known by the abbreviation EPS.
  • EPS foamed polystyrene
  • Airpop registered trademark
  • the seat 33 is defined, at least in part, by the foamed material of the section element 31.
  • at least the bottom surface 36 is defined by said foamed material.
  • the surfaces 38 and 39 are also defined by the foamed material and are connected to the bottom surface 36.
  • the shape of the section element 31, in particular the shape of the seat 33 are obtained directly by moulding, and not by cutting starting from a block of foamed material.
  • the gap present between the bottom surface 36 and the portion 22 is filled with adhesive sealing material, which is preferably in the form of a continuous strip 42 and directly connects the faces 28, 29 and 30 to the bottom surface 36.
  • adhesive sealing material is preferably in the form of a continuous strip 42 and directly connects the faces 28, 29 and 30 to the bottom surface 36.
  • this material is a structural adhesive sealant (that is, the adhesive sealant is able to create an elastic but mechanically integral bond between the panel 16 and the foamed material of the section element 31).
  • said material must be chosen from those available that are suitable for gluing glass and foamed material.
  • the gap present between the bottom surface 36 and the faces 28, 29 and 30 is completely filled with the adhesive sealing material.
  • the adhesive sealant designed to form the strip 42
  • the adhesive sealant is injected into an empty gap between the bottom surface 36 and the portion 22 of the panel 16, after having positioned the portion 22 in the seat 33.
  • the adhesive sealant suitable to form the strip 42
  • the adhesive sealant is deposited or spread on the bottom surface 36, in a still melted condition, and subsequently the portion 22 of the panel 16 is inserted in the seat 33 so as to rest against said adhesive sealant.
  • the adhesive sealant polymerizes and, by consolidating, firmly attaches to the foamed material of the bottom surface 36, to the faces 28 and 29 of the sheets 17 and 18 and to the face 30 of the spacer element 21. Thanks to this fixing process, the adhesive sealant of the strip 42 allows the bearing and support characteristics of the door 4 to be transferred to the panel 16.
  • the section element 31 comprises at least one core or stiffening insert 43, at least a part of which is embedded in the foamed material.
  • the section element 31 is defined by foamed material and by one or more inserts or cores 43, embedded in the foamed material, without further additional elements.
  • the insert 43 is completely embedded in an end portion 44 of the section element 31, which defines the surface 38 and, therefore, in use, is arranged on the outer side of the building where the window 1 is mounted.
  • the insert 43 is defined by an elongated element, parallel to the direction 32, for example a tubular element, such as to define an inner cavity 45; the core 43 can comprise a plurality of holes 46, due to which the foamed material, during the moulding, at least partially fills the cavity 45.
  • the insert 43 is arranged in a fixed position in a mould, and the foamed material is over-moulded on said insert 43.
  • the insert 43 is a metallic material, but could be in different materials, however having a stiffness greater than that of the moulded foamed material.
  • section element 31 comprises:
  • the crosspiece 12 comprises, furthermore, a plurality of gaskets 50 and possibly one or more components 51 defined by mechanisms, sensors or metal closing elements.
  • the gaskets 50 and the components 51 are brought into fixed positions by the section element 31 and, in particular, are snap-fitted or pressure coupled to retaining seats and/or retaining teeth, defined by the foamed material.
  • the gaskets 50 and/or the components 51 are glued to the section element 31.
  • the components 51 are fixed by screws, screwed into threaded seats of inserts embedded in the foamed material.
  • the crosspieces and the uprights of the framework 2 comprise respective section elements 61 which have a structure and materials similar to those of the section elements 31.
  • the foamed material of the section elements 61 is carried by at least one bracket, for example by two brackets 62 and 63 defined by extruded aluminium elements and fixed to the wall 3 by means of screws or plugs.
  • the fixing between the extruded elements 62,63 and the section element 61 is obtained by means of a layer of glue 65 and/or by means of screws 66 (screwed into one or more inserts 67, embedded in the foamed material of the section element 61).
  • Even the section elements 61 can carry one or more components 68 (and/or gaskets not illustrated), in a similar way as described above for the components 51.
  • Figures 3 to 5 relate to other embodiments.
  • the parts that form the frame 10 and the framework 2 have been denoted, where possible, by the same reference numbers used for the corresponding parts shown in Figure 2 , but followed respectively by the reference letters "a", "b” and "c".
  • the end portion 44 of Figure 2 is absent, and is replaced by a pressing element 71 which is distinct from the section element 31a and defines the surface 38a, which is coupled to the face 23 by means of a gasket 72, preferably carried in a fixed position by the pressing element 71.
  • the pressing element 71 extends along the entire length of the section element 31a and of the panel 16 and, for example, is defined by an extruded aluminium element.
  • the pressing element 71 is fixed to the portion 47a by means of screws 73, screwed into threaded seats obtained in an insert 43a embedded in the foamed material of the portion 47a. By acting on the screws 73 it is possible to bring the pressing element 71 closer to the portion 47a parallel to the direction 25 and therefore compress the gasket 72 against the face 23.
  • the panel 16 comprises two air spaces 20; the portion 44b is externally covered with a half-shell 81, which is preferably defined by an extruded aluminium element; the portion 49b is also covered by a half-shell 83, preferably in aluminium, comprising an appendage 48b, which defines the surface 39b and carries, in a fixed position, a gasket 85 arranged resting against the face 24.
  • the gasket 85 is absent, and the appendage 48b is after on the face 24 or fixed by means of an adhesive sealant.
  • the half-shells 81 and 83 are fixed to the foamed material of the section element 31b, for example by gluing or, preferably, by over-moulding of said foamed material during the production of the crosspiece 12b.
  • the half-shells 81 and 83 essentially have an aesthetic function and can be produced with a metallic material other than aluminium or with a plastic material, for example in PVC. In the specific case, they also perform a support function for the gaskets 50b.
  • the foamed material of the section element 61b is also covered by an outer half-shell 87 and an inner half-shell 89, having functions and structure similar to the half-shells 81 and 83. Furthermore, in this example, the section element 61b is placed directly on the wall 3 and fixed by means of screws, without brackets.
  • half-shells 81c, 87c and 89c similar to the corresponding half-shells 81, 87 and 89 of Figure 4 are provided, even if they preferably have a boxshaped structure so as to delimit inner channels parallel to the direction 32.
  • the portion 49c is covered by a half-shell 83c which, unlike the half-shell 83 of Figure 4 , does not define the surface 39c of the seat 33c.
  • This surface 39c is defined by a pressing element 71c distinct from the section element 31c and coupled to the face 24 by means of a gasket 72c resting on a shoulder of the pressing element 71c.
  • the pressing element 71c is substantially L-shaped, it is fixed to the portion 49c by means of screws 73c, screwed into an insert 43c embedded in the foamed material of the portion 49c, and is covered by a wall 90 which is snap-fitted or pressure coupled to the pressing element 71c.
  • the frame 10 is integrated with the panel 16, i.e. with the double-glazed unit, with a belt gluing defined by the strip 42, made of structural adhesive.
  • the frame 10 no longer has to carry out a load-bearing function, so it is possible to reduce the width of the cross-section of the frame 10, with the advantage of a larger glass surface and a minimum visual impact regarding the frame 10 itself.
  • by expanding the dimensions of the double-glazed unit defined by the panel 16 full advantage of its performance is exploited from a thermal point of view.
  • the frame 10 is, in essence, only a "glass enclosing" element that surrounds and protects the perimeter of the panel 16 (i.e. the portion 22), but does not perform the primary structural function, which instead is delegated to the glass of the panel 16.
  • the frame 10 is limited to guaranteeing air and water seal and housing and/or carrying the closing and safety mechanisms and the gaskets.
  • the material chosen to form the seat 33, 33a, 33b and 33c is then extremely insulating (it has a thermal conductivity of about 0.032 W/(m ⁇ K)). In particular, during forming it expands 50 times compared to the original volume and traps still air, while remaining resistant and rigid. In other words, the chosen material combines strength and lightness, in addition to being recyclable.
  • the window 1 not only is highly performing from the point of view of thermal insulation, but is also very advantageous on an economic level.
  • the shape and dimensions of the cross-section of the section elements which form the frame 10 and/or the framework 2 could be different from what is illustrated by way of example.
  • foamed material could be different from the one described, for example defined by foamed polymers with fire resistant or flame-retardant properties.
