Description

Window or door profile and method for assembling such profile and device used therewith. The present invention relates to a window or door profile. More specifically, the invention is intended for an insulated composite window or door profile composed of two half-shells in the form of profiles of a metal such as aluminum or steel joined together by an insulator in the form of a profile of a hard thermal insulating material, wherein the half-shells are provided with an undercut groove delimited by at least one deformable lip and wherein the insulator is germinated with its longitudinal edges in the undercut grooves (8) of the half-shells. To this end, the insulator is classically provided with longitudinal edges with a dovetail-shaped cross-section and the longitudinal edges are clamped in the grooves (8) of the half-shells by plastically deforming the deformable lip by bending this lip by rolling in or the like with permanent clamping of the dovetail-shaped longitudinal edge. result.

Current insulators have extruded crophils with a relatively complex spatial shape, which means that extrusion is required, which limits the choice of materials to materials with a low melting point,

As a result, these insulators are, for example, not suitable for use in fire-resistant or fire-retardant windows and doors. The method for rolling in the dovetail-shaped longitudinal edges is also rather complex and requires a relatively complex machine.

In addition, a separate extrusion mold is required for each width of insulator.

The object of the present invention is to provide a solution for one or more of the aforementioned and other drawbacks. To this end, the invention relates to a window or door profile composed of two half-shells in the form of profiles made of a metal such as aluminum or steel connected to each other by an isciator in the form of a profile of a hard thermal insulating material, the half-shells having an undercut groove delimited by at least one deformable lip and the half-shells being opposite each other with their undercut grooves and with their openings facing each other, the insulator with its longitudinal edges in line with the undercut grooves clampingly case in the undercut grooves of the half-shells, characterized in that the insulator is mainly in the form of a flat lath which with its longitudinal edges is elastically clamped in the grooves of the half-shells by elastic deformation of the at least one deformable lip without pl astic deformation of the material of the half-shells around the grooves,

Because a substantially flat lath is used as an insulator, its manufacture does not necessarily require extrusion and the associated limitations on low melting point materials. For example, the insulators can simply be cut from a flat plate with a thickness slightly greater than the opening of the grooves in the nalf shells. This makes it possible to simply push the insulator with its edging into the grooves of the half-shells, allowing the deformable lip or the deformable Lips of the grooves are slightly pushed apart, just enough to elastically bend the lip or lips without permanent plastic deformation, yet sufficient to permanently develop a high elastic clamping force for a strong connection between the insulator and the half-shells.

The connection can thus be established in a very simple manner by simply pushing the half-shells with their grooves transversely over the longitudinal edges of the isciator. This thus implies a very simple method and device for assembling such window and door profiles according to the invention. Moreover, such insulators can also be realized inexpensively, starting from a plate from which the insulators can simply be cut off to the desired width of the insulator.

A BE2021/5120 If applicable, a thicker plate can also be used, whereby the longitudinal edges of the cut insulator are machined to give them the desired thickness Le for elastic clamping in the grooves of the half-shells or to provide a chamfer or rounding for a better conductivity of the insulator when introduced into a half-slide groove.

The choice of a thicker plate and thus a thicker insulator Allows the strength of the composite profile to be adjusted according to the application, where, for example, in the case of a sash of a window or door, stronger profiles are required than for a fixed frame.

The undercut grooves of the half-shells may be provided with an inwardly projecting edge on the elastic lip and the longitudinal edges of the insulator may be provided with a groove into which the half-shells can hook with their inwardly projecting edge. in the case of a profile for a fire-resistant window or fire-resistant fragrance, the isclator of a composite profile according to the invention can simply be screened on one or both sides by attaching a strip to it which improves the fire-resistant properties. Consider, for example, materials that foam and/or cool down as a result of a chemical reaction,

Because the insulator is flat, use can also be made for this of flat strips of this material that are easy to apply by gluing or the like,

The invention also relates to a simple method for assembling a window or door profile starting from two half-shells in the form of profiles made of metal such as aluminum or steel, which are connected to each other by an insulator in the form of a profile made of metal. a

19 hard thermal insulating material, in which the half-shells are provided with an undercut groove bounded by at least one elastically flexible lip and in which the insulator is clamped with its longitudinal edges in the undercut grooves of the half-shells, characterized in that the method is based on an substantially flat lath-shaped insulator with longitudinal edges, the thickness of which is slightly greater than the width of the opening of undercut grooves, the method comprising the following steps:

- positioning the half-shells at a distance from each other and with the undercut grooves facing each other and with their openings facing each other;

- positioning the insulator with its longitudinal edges aligned with and directed towards the grooves of the half-shells: - pressing the half-shells laterally towards each other under pressure to elastically clamp the longitudinal edges of the insulator in the grooves by permanent elastic deformation of the the at least one elastically flexible lip;

- supporting the insulator on both sides of the insulator during the compression of the semi-acrals to prevent the insulator from buckling,

In practice, sanding of the half-shells over the longitudinal edges can be achieved by guiding the half-shells together with the insulator between them through a narrowing tapered tunnel-shaped guide, the 3 side walls of which are symmetrically located with respect to a median plane and form a narrowing guide for the half scales.

It then suffices to pull the loose half-shells together with the lcsse isclator through the tunnel, for example, or to push them through by means of driven pressure wheels. The invention also relates to a device for manufacturing a window or door profile which is composed of two half-shells in the form of profiles of a metal such as aluminum or steel joined together by an insulator in the form of a profile of a hard thermal material, the shells being provided with an undercut groove delimited by at least one elastically flexible lip and wherein the insulator is clamped with its longitudinal edges in the undercut grooves of the half-shells, the device comprising the following: - aligning means for positioning and holding the half-shells with their grooves opposite each other, with in between the insulator with its longitudinal edges opposite the grooves and supports on both sides of the insulator to maintain net k to prevent the isciator from nicking; - pressing means for pressing the half-shells towards each other for clamping the longitudinal edges of the insulator in the grooves by a suspensive elastic deformation of the at least one elastically flexible lip.

In order to better appreciate the features of the invention, some preferred embodiments of a composite window or door profile according to the invention and of a method and device used therein for assembling the profile, with reference to the accompanying drawings, in which: figure 1 schematically shows a cross-section within the framework of a glazed frame composed with profiles according to the invention: figure 2 shows the composite profile according to the invention of figure 1 separately; figures 3 and a show the separate parts of the profile of figure 2 for assembly and illustrate the method for assembling the profile; figures 5 to 8 respectively show different variants of a composite profile according to the invention; figure 9 schematically represents a device according to the invention for assembling the profile of figure 2; Figures 10 and 1 are cross-sectional views, respectively along lines X-X and XI-XI: Figure 12 illustrates the use of molds for applying the method according to the invention;

R BE2021/5120 Figure 13 Demonstrates the application of the molds of figure 12 in a device like that of figures 3 and 10 but in a modified form; figure là shows a variant of the molds of figure

12. The window 1 of the cross-section of figure 1 contains a necessary U-shaped window profile 2 according to the invention with two parallel legs, between which is received in known manner a glass or other panel 3 which has its edges between the legs by means of gaskets 4 is clamped and rests on glass supports S. The window profile 2 is shown separately in figure 2 and is composed of two half-shells 6 that form the legs of the window profile Z and an insulator 7 that connects the half-shells & together. The half-shells & are made of aluminum or steel or another metal, while the insulator 7 is made of a thermal, insulating, hard and rigid material. lips, Ga and 9b, respectively, one lip 9a of which is provided with an inwardly directed edge 10 to form an undercut. The grooves 8 face each other with their opening 11,

The insulator 7 is in this case designed as a flat slat cut, for example, from a plate and elastically clamped with its longitudinal edges 12 in the grooves 8 of the half-shells 6. The thickness D of the isclator 7 is chosen to be slightly greater than the width E of the opening 11 of the grooves 8 of the half-shells 6 in the unassembled state of rest as shown in Fig. 3, whereby in the assembled state the insulator 7 is clamped with its longitudinal edges 12 between the lips 9 of the grooves 8. The shape and the dimensions of the insulator 7 and of the grooves B are chosen so that this clamping is elastic without permanent plastic deformation of the material of the half-shells 6 around the grooves &. The shape and dimensions required for this can be calculated or determined experimentally,

The method for assembling the window profile Z is schematically shown in figure 3. The insulator 7 is for this purpose placed between two supporting surfaces, the longitudinal edges 17 to be germinated protruding on both sides, and the half-shells & are positioned on both sides of the insulator 7 with their grooves 8 aligned opposite the free longitudinal edges 12 of the isciator 7 as shown in Figure 3.

Subsequently, the half-shells 6 at the level of the insulator 7 are pressed towards each other with a force F until the longitudinal edges 12 are clamped in the grooves 8, preferably to the end in the grooves 8 as shown in figure 4.

When clamped together, the support surfaces 13 prevent the insulator 7 from buckling upwards or downwards.

Thus, the method 15 is very simple and does not require a complex shape of the insulator 7. For better guiding of the longitudinal edges 12 in the opening 11 of the grooves 8, the inwardly turned edges 10 on the Lips Sa can be slightly inclined to form a conical entrance and/or the longitudinal edges 12 of the insulator 7 may be slightly chamfered or rounded as in Figure 5.

The example of figure 1 concerns a fire-resistant window 1, in which on both sides of the insulator 7, above and below, a fire-resistant or fire-retardant strip 14 is arranged, as also shown in figure 5, which strips 14, as is known, are for instance foaming and/or cooling. properties due to exposure to high temperatures such as may be the case in the event of a fire.

In that case, it is recommended that the insulator 7 also has a better fire resistance than the actual extruded insulators, which by definition must be made of extrudable materials with a low melting temperature.

4 à BE2021/5120 Owing to the simple planar shape of the insulator 7 in the case of the invention, one does not necessarily have to resort to extrusion of the insulator 7, but one can start from a plate material with a higher melting temperature, which is, for example, higher than 300°C. An example of such material is a 3 mm thick polyodice sheet.

Figure 6 shows a window profile 2 according to the invention with, in this case, a thicker insulator 7, whose longitudinal edges 12 to be clamped have been brought to the correct thickness D by milling or the like in order to obtain the desired elastic clamping force in the half-shells 6 when clamped. The greater thickness of the insulator 7 between the half-shells 6 makes it possible to use this composite window profile 2 on windows 1 with a greater load, for example in the case of a sill where a greater strength is required than in the case of a fixed frame. In the case of FIG. 6, a slot 15 is also worked out in the longitudinal direction in the longitudinal edges 12 to be clamped in the insulator 7, in which the aforementioned but inner projecting edge 10 of the lips Ja can hook itself as in FIG. Figures 7 and & show two other variants of a composite window profile 2 according to the invention, in which, in this case, one or both, respectively,

half shells 6 are made in two parts, with a dismountable part Sa. Figures 3 and 10 show an example of device 3 and device 16 for applying the method as described above.

The device 16 in this example comprises two parallel plates 17 above each other and at a distance from each other, which 18 respectively form the top wall 17a and bottom wall 17b of a tunnel-shaped guide 18 through which the half-shells 5 and insulator 7 to be brought together will be guided for use. of the method according to the invention, and this in a feed direction À which is indicated by an arrow A in figure 3. The side walls of the tunnel-shaped guide 18 are formed by two series of compression wheels 19, each on a different side and symmetrical of a median plane M. -M' of the tunnel, the mutual distance W between the successive pressure wheels 19 becoming smaller and smaller in a linear manner in the aforesaid direction of passage from the entrance of the tunnel to the exit.

The support surfaces 13 for the insulator 7 are formed by fixed profiles of the top wall 17a and of the bottom wall 175 at a distance from each other such that the insulator 7 can be passed through with a minimum clearance between the support surfaces 13, 36 in the top wall 17a are guide grooves. 20 provided for guiding with a certain play the upper edge of the nalf shells 6° in one direction tangential to the sanding wheels 19 as shown in dashed line in figure

8.

In the profile of the lower supporting surface 13 of the insulator 7, recesses 21 are provided for supporting the half-shells 6 with the grooves 8 directly opposite the longitudinal edges 12 of the insulator 7. In addition to the supporting surfaces 13, sufficient space is provided for the elastic movement of the lips 9 when clamping the insulator 7. The device 16 is further provided with a drive (not shown in the figures) for pushing or pushing the half-shells 6 together with the insulator 7 in their longitudinal direction in the feed direction A through the tunnel. pulling, for example by means of a windable cable on a winch arranged downstream of the tunnel.

The use of the device is very simple and as follows. The half shells 6 are forced through the tunnel together with insulator 7 between them.

The outer sides of the half-shells 6 come into contact with the pressure wheels 19, which gradually force the half-shells © more and more in the direction of the median plane M-M and of the insulator 7.

“A BE2021/5120 exert pressure force PF whereby they are pushed with their grooves 8 over the longitudinal edges 12 of the insulator 7.

Figure 10 shows the situation at the location of the first pressure wheels 19 at the entrance to the tunnel where the isciator 7 is still loose, while figure 11 shows the same situation at the location of the last pressure wheels 19 at the exit of the tunnel. where the longitudinal edges 12 of the insulator 7 are pushed completely into the grooves 8 of the half-shells 6 and in this way a user-friendly composite window profile 2 is obtained that only needs to be brought to the correct length or can undergo further finishing without the however, it is necessary to deform the lips 9 of the grooves 8 of the half-shells 6 even further. Figures 12 and 13 show a slightly modified device with flat top and bottom walls 17a and 175, in which case chainmail is used to support the half-shells 6 and the isclator 7 and align them during their trajectory. throughout the device 16, Vaartoe use is made of an outer mold 22 in the form of two U-profiles 23 which are extended with their openings directed towards each other between the pressure wheels 19 and which are laterally slidably supported between the top and bottom walls 17a and 17b of the Lunel.

These U-profiles 23 are slid over the half-shells 6 and support the half-shells 6 in a vertical position along the length of the half-shells 6.

3 The separate insulator 7 is supported in an analogous manner in the outer mold 22 by an inner mold 24 with an upper mold Z4a and a lower mold 240 with support surfaces 13 between which the insulator 7 is arranged and which are arranged laterally slidably between the legs of the folding mold 22. a set of molds 22 and 24 including the half-slides 5 and insulator 7 is then guided between the pressure wheels 19 of the device of figure 13, whereby the U-profiles 23 of the outer mold 22 are forced together with the half-shales & towards each other, with the insulator 7 clamped at the end between the half-shells 6 as in figure 13. A variant of an inner mold 24 is shown in [figure 14, in which case the upper mold 24a and the lower mold 24b consist of two loose parts, each of which is separate can be moved laterally in the outer mold 22. The drive for the half-shells &, the insulator 7 and, if necessary, the mails 22 and 24 can be arranged in any way run, for instance by means of a pulling cable which is wound on a winch or because the pressure wheels 19 are designed as pulling wheels 19 with their own drive.

; BE2021/5120 16 It is clear that instead of pressure wheels 19, full straight tunnel walls can also be fitted in Teflon or in other material with a low shear resistance. 3 When in the foregoing a direction or position is indicated such as above/below, sideways, front/back and | such is not to be considered a ; absolute asandulding but rather as an indication to the figures,

The present invention is by no means limited to the embodiments described by way of example and embodiments shown in the figures, but a window or door profile according to the invention and thereby a method and device for assembling such a profile can be realized in all kinds of shapes and dimensions without going beyond the scope of the invention. within the scope of the invention.
