The mutual joining of the two sectional elements (1-2) constituting the node (F) of the external closing fixture is obtained for the mobile leaf (7) through a jointing means constituted by the self-tapping screws (6) normally used for constraining the rail or plate (3) of the perimetral hardware. The self-tapping screws (6) constrain said two sectional elements (1-2) through the protuberances (4-5) with which the sectional elements (1-2) themselves, respectively, are provided. The mutual joining of the two sectional elements (1-2) constituting the node (F) of the external closing fixture is obtained for the frame (8) through a jointing means constituted by the self-tapping screws (6) normally used for constraining the closing striker blocks (18) of the perimetral hardware. The jointing is obtained by following an innovative method for insertion of the multiglazing pane (48) by pressing together said sectional elements (1-2) constituting the mobile leaf (7). The internal hide-away hinges (10) are mounted within the node of the frame (F), thus enabling preferred lengthening of the thermally insulating profile.

Description

METHOD FOR JOINING AND COUPLING A COUPLE OF PROFILES OF DIFFERENT MATERIALS, CONSTITUTING THE LEAF AND THE
FRAME OF AN EXTERNAL FIXTURE
The present invention relates to an innovative method for jointing and coupling sectional elements to be used for the production of closing fixtures such as doors and windows in the residential, public, commercial and industrial building sector. The innovative method has been devised for solving the problem of jointing a pair of sectional elements made of different materials constituting an external closing fixture, for example coupling in an unremovable way a sectional element made of aluminium with a co-extruded sectional element formed externally by rigid PVC and internally by foamed PVC filled with wood flour, constituting the external part and internal part, respectively, of a closing fixture.
Currently, in the known art, the installation of the perimetral hardware is obtained, on the sectional element of the mobile leaf, using self-tapping screws for anchorage of the steel plate (16 mm wide, set bearing upon the sectional elements of the mobile leaf and usually made of just one material such as aluminium, PVC, wood, etc.) in order to enable movement of the leaf itself with respect to the frame of the closing fixture, while using, on the sectional element of the frame, self-tapping screws for anchorage of the closing striker blocks.
In the case where the mobile leaf or the frame of the closing fixture is/are constituted by the union of two mutually jointable sectional elements made of different materials (aluminium and foamed PVC) , said hardware can be used in an innovative way also for solving definitively the problem of anchorage of said two mutually jointable sectional elements that constitute the side node of the closing fixture, provided that said sectional elements are shaped in such a way as to enable' their mutual constraint by means of the plate and of the striker blocks of the hardware with said self-tapping screws.
The present method is altogether new in so far as up to the present day it has never been applied in the known art and constitutes an inventive step in so far as it solves the problem of mutual constraint of two sectional elements made of mixed materials coupled together by means of the hardware in order to produce the side node of an external closing fixture.
The main purpose of the present invention is precisely to provide a jointing method in order to solve the problem of jointing a pair of sectional elements made of different materials constituting the side node of an external closing fixture.
The purposes are achieved by providing an innovative method for coupling sectional elements to be used for the production of closing fixtures in the residential, public, commercial, and industrial building sector as characterized in the ensuing claims.
These purposes and the consequent advantages, as well as the characteristics of the invention according to the present disclosure will emerge more clearly from the ensuing detailed description of a preferred solution, provided by way of non-limiting example, with reference to the attached drawings, in which:
- Figure 1 is a cross-sectional portion of a preferred solution of a node F of the closing fixture constituted by a mobile leaf 7 and a frame 8, where the mobile leaf 7 and the frame 8 are constituted by a pair of sectional elements 1-2, which, in a preferred solution, are a sectional element made of aluminium 1 with a sectional element made of PVC 2 that is co- extruded with foamed PVC filled with wood flour or similar products, rigidly jointed together by means of a plurality of self-tapping screws 6 constrained in the protuberances 4-5, namely, the protuberances 4 belonging to the sectional elements made of aluminium 1 and the protuberances 5 belonging to the sectional element made of PVC 2, with the screws 6 screwed through the plate 3 or the steel striker block 18 of the perimetral hardware of the closing fixture? there may likewise be noted the presence of a central rebate fin 11, typical of an open joint, a hinge in view 9, an internal rebate gasket 12, a pair of gaskets 69, and a multiglazing pane 48;
- Figure 2 is a portion of the node F of Figure 1, where just the mobile leaf 7 is represented, constituted by said pair of sectional elements 1-2, with the variant that the plate 3 now rests only on the aluminium sectional element 1 and does not straddle both the aluminium sectional element 1 and the co- extruded PVC sectional element 2, unlike what is represented in Figure 1; - Figure 3 is a portion of the node F of Figure 1, where just the mobile leaf 7 is represented, with the variant that the plate 3 now rests only on the sectional element made of co-extruded PVC 2;
- Figure 4 is a cross-sectional portion of a preferred solution of a central node Fl of the closing fixture according to the invention, constituted by a pair of mobile leaves 7 and a reverse rebate 90, once again where the mobile leaf 7 and the reverse rebate 90 are constituted by a pair of sectional elements 1-2;
- Figure 5 is a cross-sectional portion of a leaf 7 of the closing fixture according to the invention, where there now appears a third sectional connection element 14, made of polyamide or fibre-glass, in order to increase the thermal insulation of the closing fixture, given that the screws 6 indirectly block the aluminium section 1 with the foamed-PVC section 2 via the constraint of said sectional element 14;
- Figure 6 is a cross-sectional portion of another innovative solution of a leaf 7 of the closing fixture according to the invention, this being a variant of the solution illustrated in Figure 4, where now said third sectional connection element 14 clearly separates the aluminium section 1 from the foamed-PVC section 2;
- Figure 7 is a cross-sectional portion of a second preferred solution of a node F of the closing fixture constituted by a mobile leaf 7 and a frame 8, which is different from the previous one illustrated in Figure 1 in that it is provided with an external rebate gasket 13, instead of the central fin 11, to obtain a double- rebate gasket solution, with internal rebate 12 and external rebate 13, in order to enable a reduction of up to 53 mm in width of the mobile leaf 7 ;
- Figure 8 is a view of just the cross section of the mobile leaf 7 illustrated in Figure 6, where now said third sectional connection element 14 clearly separates the aluminium section 1 from the co-extruded- PVC section 2;
- Figure 9 is another preferred solution of a node F as represented in Figure 1, where now instead of the hinge in view 9, there is present a concealed or hideaway hinge 10, which enables a considerable increase in the depth of the cross section of the sectional element made of co-extruded foamed PVC 2, thus enhancing the thermal insulation of the node F;
- Figure 10 is another preferred solution of a node
F as represented in Figure 8, where now a plurality of cleats 16 are present < for joining the corners of the two sectional elements made of co-extruded foamed PVC 2 (as regards the aluminium sections 1 of the previous figures, said cleats 16 are always inserted inside them, but it has been preferred to represent them only in this figure) , as well as a multi-glazing pane (here a triple-glazing pane) 15, further enhancing thermal insulation;
- Figure 11 is a cross-sectional portion of another innovative solution of a node F of the closing fixture according to the invention, with both the sectional element 2 of the leaf 7 and the sectional element 2 of the frame 8 that are completely made of foamed PVC and/or extruded foamed PVC filled with wood flour or similar filling means, both of which are co-extruded externally with an extremely thin laminate of rigid PVC with aesthetic function, said cross-sectional portion regarding the node F of the closing fixture itself with L-shaped frame and triple-glazing 10 being designed to be suitable for installation of accessories of the perimetral type with 16-mm groove and hide-away hinges.
From the attached figures a person skilled in the branch may readily appreciate that the inventive method of coupling sectional elements 1-2 to be used for the production of closing fixtures in the residential, public, commercial and industrial building sector is obtained precisely via installation with self-tapping screws 6 of the plate or rail 3 as likewise of the striker block 18 of the perimetral hardware, with the innovation that said hardware is installed after insertion of the multiglazing. The present method is new and inventive in so far as up to the present day nobody has ever thought of mounting first the multiglazing 15 and then the hardware 3 in so far as on current sectional elements made of aluminium, rigid PVC, wood, etc. there has always been mounted first the hardware and then the multiglazing using glazing beads. The inventive idea stems precisely from the fact that the hardware 3 thus installed after insertion of the multiglazing 15, using said screws 6, enables joining of the two sectional elements 1-2, coupling them so that they are rigidly constrained together, likewise preventing opening of the corners of the section of the more compliant material when the inner gasket of the multiglazing 15 is inserted by applying pressure. The sectional elements 1-2 constituting the mobile leaf 7 and the frame 8 of an external closing fixture may be made of various materials available on the market, such as for example, in the preferred solutions represented in the attached figures, those constituted by an aluminium sectional element 1 and a co-extruded sectional element of rigid PVC made internally of foamed PVC 2 filled with wood flour. The self-tapping screws 6 constrain said two sectional elements 1-2 through the protuberances 4-5 with which the sectional elements 1-2, respectively, are provided. The self- tapping screws 6 can constrain said sectional elements 1-2 also through just one of said protuberances 4-5, if a third sectional element 14 is inserted, positioned in an intermediate way between the sectional elements 1-2 themselves to be coupled in a rigidly constrained way.
In a preferred non-limiting embodiment, said third sectional element 14 is made of foamed PVC filled with wood flour and co-extruded with rigid PVC or recycled PVC (alternatively, it may be made of polyamide, fibre- glass or other similar materials), thus reducing the thermal transmittance of said node F.
The internal hide-away hinges 10 are mounted within the node of the frame F, likewise enabling a preferred lengthening of the thermally insulating profile for the purposes of enhancing thermal insulation. To render operational installation of the closing fixture more convenient, the latter may be already pre-assembled in the factory by preparing two sectional elements of the leaf and of the frame constituted, respectively, by said aluminium sectional elements 1, joined by cleats 16, and said PVC sectional elements 2 welded using machines for welding PVC or joined by cleats on the mobile leaf 7. The present method enables time saving, above all in the absence of welds, in so far as for installation of the closing fixture there only twelve cuts are now necessary on the coupled bars of said sectional elements 1-2, instead of the customary thirty-two cuts necessary for the rigid PVC sectional element and twenty for the sectional element made of aluminium or wood.
The method for jointing and coupling a pair of sectional elements 1-2 made of different materials that constitute both the mobile leaf 7 and the frame 8 is characterized precisely in that the mutual joining of said pair of sectional elements 1-2, each provided with at least one protuberance 4-5, respectively, is obtained through a jointing means constituted by the self-tapping screws 6, normally used for constraining the rail or plate 3 of any perimetral hardware, said self-tapping screws 6 rigidly constraining together said two sectional elements 1-2 through said protuberances 4-5, said mobile leaf 7, together with the frame 8, constituting the side node F of the closing fixture. Said self-tapping screws 6 can constrain the pair of sectional elements 1-2 of the leaf 7 through at least just one of said protuberances 4-5 and a third sectional element 14, the latter being inserted in an intermediate way between the pair of sectional elements 1-2. Said third sectional element 14 is constituted, in a preferred non-limiting solution, by polyamide or fibre-glass or other material with low thermal conductivity.
The node F, formed by the jointing of said mobile leaf 7 with said frame 8 via said screws 6 of the accessories of the perimetral type, is constituted by coupling a first, external, load-bearing aluminium sectional element 1 and a second, internal, sectional element 2 , which is also load-bearing, but is made of extruded foamed PVC or of extruded foamed PVC filled with wood flour or other similar filling means.
The second, internal, sectional element 2 made of extruded foamed PVC, may also be constituted by recycled PVC, which is, in turn, finely ground and possibly mixed with wood flour or other similar products .
The second, internal, sectional element 2 may also be of a co-extruded type made of rigid PVC 17, ranging in thickness from a minimum of 0.3 mm to a maximum of 2 mm on the external part of the sectional element made of foamed PVC.
The second sectional element 2 may also be obtained by co-extrusion with material constituted by recycled and finely ground rigid virgin PVC.
The second, internal, sectional element 2 made of recycled extruded foamed PVC, may likewise be coated with a laminate of a CPL (Continuous Pressure Laminate) type applied as film with a machine for coating sectional elements or rotogravure printed using purposely designed plane-parallel machinery.
The section of the leaf 7 and the section of the frame 8 may be obtained with a multiglazed conformation and accessories of the perimetral type in order to enhance insulation of the node F.
The reinforcement means 28-29 for the leaf 7 of the closing fixture are constituted by sectional elements made of fibre-glass or polyamide, with the first reinforcement means 28 set on the outside to bestow greater resistance of the closing fixture to the force of the wind and with the second reinforcement means 29 set on the inside for supporting the screws of the hinges.
The reinforcement means 28-29 for the frame 8 of the closing fixture are constituted by sectional elements made of fibre-glass or polyamide, with the first reinforcement means 28 set on the outside to bestow greater resistance of the closing fixture to the force of the wind and with the second reinforcement means 29 set on the inside for supporting the screws of the hinges, as well as with both of said reinforcement means 28-29 used also for anchorage to the jamb of the frame 8.
According to the present invention, the method for jointing and coupling said pair of sectional elements 1-2 made of different materials constituting the mobile leaf 7 of an external closing fixture for the residential, public, commercial, or industrial building sector is hence innovative and inventive in so far as it is characterized also in that the installation of the pane 48 during production of the closing fixture is performed by pressing said different materials of the closing fixture constituting the mobile leaf 7 together. With said pressure of the aluminium on the foamed PVC filled with wood flour or recycled PVC 2 between which the double- or triple-glazing pane is inserted there is achieved the dual advantage of obtaining in a fast way a perfect seal of the pane 48 itself - traditionally carried out manually or using a machine with high labour costs and defectiveness of installation - in so far as said pane 48, held in place by a pair of gaskets 69, previously inserted by sliding them between said elements 1-2, eliminates, with said modality of coupling under mutual pressure of said elements 1-2, any possible warping or misalignment of said sectional elements 1-2 that constitute the mobile leaf 7, thus optimizing respect of the dimensional tolerances of production in the extrusion of both of the sectional elements 1-2.
Figure 4 also represents a cross-sectional portion of a preferred solution of a central node Fl of the closing fixture according to the invention, constituted by a pair of mobile leaves 7 and a reverse rebate 90. In Figure 4 it emerges clearly how the mobile leaf 7 and the reverse rebate 90 are both constituted by a pair of sectional elements 1-2 joined by the plate 3 of the perimetral hardware both on the mobile leaf 7 and on the reverse rebate 90.
The advantages of the present method are likewise represented by the ease of manufacture, assembly in the factory, and installation of the end product thus obtained.
A further advantage of the present invention is represented by the fact that it reduces considerably the costs of production of said closing fixtures given the same coefficient of thermal transmittance . It is also evident that numerous minor alterations , adaptations, integrations, variations may be made to the embodiment previously described purely by way of illustrative and non-limiting example, as well as replacement of elements with other functionally equivalent ones, without thereby departing from the sphere of protection of the ensuing claims.
