Definitions

  • the present invention relates to a set of cold metal section bars which are convertible into thermally-broken section bars suitable for cold door and window frames and for thermally-broken (insulated) door and window frames.
  • Thermally-broken section bars in turn, can be of different type.
  • thermally-broken section bar is obtained from two metal section bars, one internal and the other external, extruded separately, that are joined together by means of hars of insulating material inserted in specially-provided seats and then clamped through a rolling process.
  • the two internal and external elements can have a non-uniform anodization and their aging can also be non-uniform.
  • thermally-broken section bar is obtained from a whole metal section bar provided with a tubular casing that connects the elements of the internal and external metal section bars, extruded in one single piece.
  • polyurethane foam is injected into the tubular casing and the metal walls of the tubular casing connecting the elements of internal and external metal section bars are then removed, by means of a cutting operation, so that the two internal and external elements remain connected together only through the injected polyurethane foam.
  • This thermally-broken section bar does not have the drawbacks of the section bar with separate internal and external elements, but it does require a laborious and expensive manufacturing process, that cannot be executed by an assembler of door and window frames, due to the complexity of the operations of injecting foam into the tubular casing and of subsequently cutting the walls connecting the internal and external section bar elements.
  • the object of the present invention is a set of flexible section bars constituted by whole metal section bars, extruded in one single piece, that can be used as cold section bars and can be converted into thermally-broken section bars with simple operations, that may also be executed outside the production line of the section bars, thus that can also be executed by an assembler of door and window frames when it becomes necessary to manufacture a thermally-broken section bar, rather than a cold section bar.
  • Another object of the present invention is a set of section bars that have an optimum conformation both as cold metal section bars and as thermally-broken section bars, obtained by the transformation of the cold metal section bars.
  • a set of cold metal section bars which are convertible into thermally-broken section bars, particularly for door and window frames, each comprising an element of internal metal section bar and an element of external metal section bar connected together by means of connecting walls, characterized in that said connecting walls are made of metal and comprise teeth linked to said elements of internal and external section bars by means of weakening lines suitable for making them deformable, and strips connected to said deformable teeth by means of further weakening lines suitable for making them removable, the thickness of said strips being less than the thickness of said teeth, said elements of internal and external section bar are provided with longitudinal recesses each formed by one of said deformable teeth, by at least one rigid ridge substantially parallel to said teeth and by a back wall connecting one tooth and one ridge, and said element of external section bar comprises at least one abutment fin connected to at least one of said back walls by means of a connecting tang protruding outward, so as to form a chamber for aeration and for collection of water in
  • said element of internal section bar is provided with at least two longitudinal recesses arranged at a distance greater than that at which two corresponding longitudinal recesses of the element of external section bar are arranged and said removable strips are inclined with respect to said back wall, converging toward said element of external section bar, so as to carry any water and condensate toward said collection chamber.
  • said abutment fin has a substantially convex wall, so that deformations of said teeth involve only variations in the curvature of the fin.
  • a set of thermally-broken section bars each comprising an element of internal metal section bar and an element of external metal section bar connected together by means of insulating bars housed in matching longitudinal recesses of an element of internal section bar and of an element of external section bar, characterized in that said longitudinal recesses are each formed by a deformable tooth, by at least one rigid ridge substantially parallel to said tooth and by a back wall connecting one tooth and one ridge, said tooth being connected to the respective element of internal and external metal section bar by means of a weakening line suitable for making it easier to fold them over extremities of said insulating bars, so as to clamp them in said recesses leaving an air space between them, and said element of external section bar comprises at least one abutment fin connected to at least one of said back walls by means of a connecting tang protruding outward, so as to form a chamber for aeration and for collection of water in the proximity of said fin and to minimize the transmission
  • said insulating bars are arranged inclined with respect to said back wall, converging towards said element of external section bar, so as to carry any water and condensate toward said collection chamber.
  • section bars according to the invention there is the great advantage of being able to produce unified section bars, that have an optimized conformation as regards weight, strength and performance, both when they are utilized as cold section bars and when they are utilized, after an easy and simple conversion, as thermally-broken section bars.
  • the transversal resistant cross-section of the cold section bars is dimensioned so that a reduced resistant cross-section of the removable strips, due to a lesser thickness than that of the teeth, is substantially compensated by that of the rigid ridges.
  • the weight of the material that is removed and discarded in the case of transformation into thermally-broken section bars is thus reduced to a minimum.
  • the ridges, together with the teeth form longitudinal recesses suitable for housing insulating bars, keeping them at a distance from one another, so that they remain separated by an air space and an effective thermal insulation is obtained.
  • the operations of conversion can also be executed outside the plant that manufactures the section bars, by an assembler of door and window frames when it becomes necessary to install a thermally-broken door and window frame.
  • the conversion requires very simple interventions, that consist in the insertion of insulating bars in the matching longitudinal recesses of the elements of internal and external section bar, in the removal of the strips cutting them along their respective weakening lines and in folding the teeth with respect to the respective weakening lines, so as to firmly fasten ends of the insulating bars in the corresponding longitudinal recesses.
  • Another advantage of the set of unified section bars, made according to the invention, is represented by the possibility of carrying toward draining holes water and condensate that may infiltrate inside the door and window frames both in the case of cold door and window frames and in the case of thermally-broken door and window frames. Carrying is executed through the inclined arrangement of the removable strips, converging toward the element of external section bar in cold section bars, and through the inclined arrangement of the insulating bars, that also converge toward the element of external section bar in thermally-broken section bars.
  • the substantially convex shape of the abutment fin introduces a good margin of tolerance against possible deformations caused by the bending of the teeth, because the deformations involve only variations in the curvature of the fin, that can be discerned by the naked eye only with difficulty.
  • the convex shape is also favourable from an aesthetic viewpoint.
  • a cold metal section bar having a transversal cross-section substantially in the shape of a "Z", made by extrusion, preferably in an aluminium alloy.
  • the section bar 1 comprises an element of internal section bar 7 and an element of external section bar 8 connected by means of connecting walls 9.
  • the connecting walls 9 are formed by deformable longitudinal teeth 11 and by removable longitudinal strips 12 having a thickness that is less than the thickness of the teeth 11.
  • the strips 12 are connected to the teeth 11 by means of longitudinal weakening lines 13 suitable for making it easier to cut them; the teeth 11 are connected to the elements of internal section bar 7 and of external section bar 8 by means of weakening lines 14 suitable for making it easier to bend them, as also shown in Fig. 13.
  • the elements of internal section bar 7 and of external section bar 8 are provided with rigid ridges 15 substantially parallel to the teeth 11, that with back walls 16 and with the teeth 11 form longitudinal recesses 18.
  • the recesses 18 belonging to the element of internal section bar 7 are arranged at a distance greater than that at which the recesses 18 belonging to the correspondng element of external metal section bar 8 are arranged and, thus, the strips 12 are inclined with respect to the back walls 16 and converge toward the element of external section bar 8, so as to carry water and condensate toward a chamber 19 for aeration and collection of water and condensate.
  • the element of external section bar 8 comprises an abutment fin 21 formed by a substantially convex wall, so that deformations of the teeth 11 involve only variations in the curvature of the fin.
  • the fin 21 is provided with a "C"-shaped seat 22 suitable for housing a seal and an alignment bracket, not shown.
  • the fin 21 is linked to the back walls 16 by means of a connecting tang 23 protruding outward, with which it forms the abovementioned chamber 19, so as to minimize the transmission of deformations from the teeth 11 to the fin 21. With the fin 21 there is integral a resting tang 31.
  • the element of internal section bar 7 is formed by a tubular casing 24, having a substantially rectangular transversal cross-section, with which there is integral an abutment fin 25, provided with a C-shaped seat 26 for a seal.
  • a tubular casing 24 In the tubular casing 24 there is a C-shaped seat 27 suitable for housing a hinged element or a glass-holding section bar, a U-shaped seat 28, suitable for housing a seal or a self-tapping screw, as shown in Fig. 19.
  • section bar 1 From the section bar 1 it is possible to obtain a thermally-broken section bar, similar to that indicated in Fig. 2 as a whole with 10, wherein the parts like to those of section bar 1 are indicated with the same reference numbers.
  • a pair of insulating bars 29 is inserted into the matching recesses 18 of the section bar elements 7 and 8, as shown in Fig. 13, and the strips 12 are then cut from the teeth 11, so as to divide the element of internal section bar 7 from the element of external section bar 8. Moreover, the deformable teeth 11 are folded with respect to the weakening lines 14, so as to clamp the extremities of the insulating bars 29 in the recesses 18, as shown in Fig. 2, leaving an air space 17 between the bars.
  • the bars 29 are inclined like the strips 12, converging toward the element of external section bar 8 and their extremities 29a have a trapeze-like shape, on which the teeth 11 are folded.
  • the insulating bars 29 are preferably made of polyamide reinforced with glass fibres.
  • the section bars 1 and 10 have an optimized conformation both as cold section bars, and as thermally-broken section bars, as regards weight, resistance, performance.
  • the transversal cross-section of the cold section bars resistant to operational stresses is obtained by reducing the resistant cross-section of the removable strips, as their thickness is less than that of the teeth, and substantially compensating it with that of the rigid ridges.
  • the weight of the material that is removed and discarded in the case of the conversion in thermally-broken section bars is thus very small.
  • the thermally-broken section bar 10 the pair of insulating bars 29, separated by an air space 17, allows an effective thermal insulation to be obtained.
  • an assembler of door and window frames can convert the cold section bar 1 into the thermally-broken section bar 10 with few and simple operations, thus outside the production line of the section bars.
  • a cold metal section bar 2 having a substantially Z-shaped transversal cross-section, wherein the parts like or corresponding to those of the section bar 1 of Fig. 1 are indicated with the same reference numbers.
  • the abutment fin 21 of the section bar 2 is provided with the resting tang 31 and with a bent extremity 32.
  • the tubular casing 24 has a C-shaped seat 33 suitable for housing a hinge element or for joining up with another section bar, and a resting tang 34.
  • FIG. 4 a thermally-broken section bar 20 obtained from the section bar 2 with the same operations described earlier with reference to the conversion of the cold section bar 1 into the thermally-broken section bar 10.
  • the parts like to those of the section bars 2 and 10 are indicated with the same reference numbers.
  • Figs. 5 and 6 There are shown in Figs. 5 and 6 a cold metal section bar 3 and a thermally-broken section bar 30 obtained from the section bar 3 having a substantially Z-shaped transversal cross-section.
  • the element of external section bar 8 has a tubular casing 35 to which there are integral the tang 23 and two rigid ridges 15 that, with the back walls 16 and the deformable teeth 11, form the recesses 18.
  • the parts like or corresponding to those of the section bars 1, 10 and 3, 30 are indicated with the same reference numbers.
  • the tubular casing 24 there are integral resting tangs 36 suitable for engaging with another section bar and a double-C seat 37 for a hinge element, for a clamping rod (bolt) of a movable part and for a supplementary lock match.
  • a resting seat 38 suitable for engaging with another section bar.
  • the parts like or corresponding to those of the section bars 7 and 8 are indicated with the same reference numbers.
  • Figs. 11 and 12 There are shown in Figs. 11 and 12 a cold metal section bar 6 and a thermally-broken section bar 60 obtained from the section bar 6 having a substantially T-shaped transversal cross-section.
  • the parts like or corresponding to those of the section bars 1 and 10 are indicated with the same reference numbers.
  • Fig. 14 there is represented diagrammatically a cold door and window frame with a side hung pane comprising a fixed frame 41 made with section bars 1 and a movable frame 42 made with section bars 2. There is indicated with 43 a sealing gasket housed in the seat 28, that makes abutment against the tang 34 of the section bar 2.
  • Fig. 15 there is represented diagrammatically a thermally-broken door and window frame with a side hung pane comprising a fixed frame 44 made with section bars 10 and a movable frame 45 made with section bars 20.
