Description

Window or door profile and method for assembling such profile and device used therein. 9 3 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 LO 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 sen. hard thermal insulating material, in which the half-shells are provided with an undercut groove bounded by at least one deformable lip and in which the insulator with its longitudinal edges is clamped 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 over by rolling in or the like, resulting in permanent germination of the dovetail-shaped longitudinal edge.

The current isclators have extruded profiles 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.

> BE2021/5120 As a result, these insulators are not suitable for use in, for example, fire-resistant or fire-retardant windows and doors, S The method for rolling in the dovetail-shaped longitudinal edges is also rather complex and requires a relatively complex machine. require a separate extrusion mold.

The object of the present invention is to provide a solution to 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 are connected to each other by an insulator 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 insulator being clamped with its longitudinal edges in the undercut grooves of the half-shells, characterized in that the isciator is essentially in the form of a flat batten elastically clamped with its longitudinal edges in the grooves of the half-shells by elastic deformation of at least one deformable iiD without plastic deformation of the material of the half-shells around the grooves .

Because a mainly flat batten is used as an insulator, one does not necessarily have to rely on extrusion for its manufacture and the associated restrictions in the field of materials with a low S melting point. 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 half-shells.

This makes it possible to simply push the insulator with its longitudinal edges into the grooves of the half-shells, causing the deformable lip or the deformable lips of the grooves to be pushed slightly apart, just enough to elastically bend the lip or the lying pin without permanent damage. plastic deformation, yet sufficient to permanently develop a large elastic clamping force for a strong connection between the isclator 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 insulator. This thus implies a very simple method and device for assembling such window and door profiles according to the invention. .

Moreover, such insulators are also cheap to realize starting from a plate from which the insulators can simply be cut off to the desired width of the insulator,

If necessary, it is also possible to start from a thicker plate, whereby the longitudinal edges of the cut insulator are machined to give them the desired thickness Le for an elastic clamping in the grooves of the half-shells or to provide a chamfer or rounding for a better orientation of the insulator when introduced into a groove of a naif shell.

The choice of a thicker plate and thus of a thicker insulator makes it possible to adapt the strength of the composite profile 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 isciator 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 door, the insulator of a composite profile according to the invention can simply be shielded on one or both sides by attaching a strip to it that improves the fire-resistant properties. that foam and/or cool down as a result of a chemical reaction

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

3 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 of a metal such as aluminum or steel, which are connected to each other by an insulator in the form of a profile of a hard thermal insulating material, in which the half-shells are provided with an undercut groove delimited 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 a essentially 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: ZU - positioning the half-shells at a distance from each other and with the undercut grooves facing each other and with hin openings facing each other; - positioning the insulator with its longitudinal edges aligned with and facing the grooves of the half-shells; - pressing the half-shells laterally towards each other under pressure for elastic clamping of the longitudinal edges of the insulator in the grooves by permanent elastic deformation of the at least one elastically flexible lip; - supporting the insulator on both sides of the insulator while pressing the half-slides to prevent the insulator from buckling.

& BE2021/5120 In practice, the pressing of the half-shells over the longitudinal edges can be achieved by guiding the nalf-shells together with the insulator between them through a # S narrowing tunnei-shaped guide { whose side walls are symmetrically located with respect to a median plane and form a narrowing guide for the half shells.

It is then sufficient to pull the separate half-shells together with the separate insulator, for example through the tunnel or to push it 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 insulating material, the half-shells having 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: = alignment and support means for positioning and holding the half-shells with their grooves on top of each other, with the insulator in between with its longitudinal edges opposite the grooves; - pressing means for pressing the semi-slides towards each other Loe for clamping the longitudinal edges of the insulator in the grooves by permanent elastic deformation of the at least one elastically flexible lip.

In order to better demonstrate the features of the invention, some preferred embodiments of a composite window or door profile according to the invention and of a Love-appropriate method and device for assembling the profile are described below, by way of example without any limiting character. , with reference to the accompanying drawings, in which: figure 1 schematically represents a cross-section in 9 within the framework of a glazed window composed with profiles according to the invention: figure 2 shows the assembled profile according to the invention of figure 1 separately; figures 3 and 4 the separate parts of the profile of | Figure 2 shows before assembly and illustrates 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 11 show a section along lines X-X and XI-XI, respectively; figure 12 illustrates the use of molds for applying the method according to the invention:

& BE2021/5120 figure 13 the application tcont of the chainmail of figure iz in a device like that of figures 9 and 10 but in a fixed form; figure 14 shows a variant of the molds of figure

12. The window 1 of the cross-section of figure 1 comprises a substantially U-shaped window profile 2 according to the invention with two parallel legs, between which is received in a known manner a 19 glass or other panel 3 which has its edges between the edges by means of gaskets 4 the legs is clamped and rests on class supports 5. The window profile! 2 is shown separately in figure 2 and is composed of two half-shells 6 that form the legs of the diamond profile 2 and an insulator 7 that connects the half-shells 6 together. The half-shells 6 are made of aluminum or steel or other metal, while the Insulator 7 is made of a thermal, insulating, hard and rigid material. The half shells 6 are provided on their sides facing each other with an undercut groove 8, which in this case is delimited by two upright lips, respectively 2a and 9b, of which one lip Sa is provided with an inwardly directed vane 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-slides 6.

The thickness D of the insulator 7 is chosen to be slightly greater than the width E of the opening 11 of the grooves 8 of the half-shells in the unassembled state of rest as shown in Figure 3, where in the assembled LID state the insulator 7 clamps with its longitudinal edges 12 between the lips 9 of the grooves 8. The shape and dimensions of the insulator 7 and of the grooves 8 are chosen such that this clamping is elastic LS without permanent plastic deformation of the material of the halyards 6 around the grooves &. The shape and dimensions required for this can be calculated or determined experimentally. The method of assembling the window profile 2 is schematically shown in figure 3. The insulator 7 is for this purpose arranged between two supporting surfaces, the longitudinal edges to be clamped. 12 protrude on each side, and the half-shells & are positioned on each side of the insulator 7 with their grooves 8 aligned opposite the free longitudinal edges 12 of the insulator 7 as shown in Figure 3.

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

During the germination, the support surfaces 13 prevent the insulator 7 from buckling upwards or downwards. The method is thus very simple and does not require a complex shape of the insulator 7. For a better guiding of the longitudinal edges 12 in the opening. 11 of the grooves 8, the inwardly facing edges 10 on the tabs Za may be slightly angled to form a conical entrance and/or the longitudinal edges 12 of the insulator 7 may be slightly beveled or rounded as in Figure 5. example of figure 1 concerns a fire-resistant window 1, in which a fire-resistant or fire-retardant strip 14 is arranged on both sides of the insulator 7, above and below, as also shown in figure 5, which strips 14, as is known, have, for example, foaming and/or cooling properties. when exposed 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 better fire resistance than the current extruded insulators which by definition must be made of extrudable materials with a low melting temperature. 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 sheet material with a higher melting temperature, for example higher than 300°C.

An example of such material is a 3 mm thick polycdice plate.

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 in 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 with a higher load, for example in the case of a sash where a greater strength is required than in the case of a fixed frame .

in the case of Fig. 6, a groove 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 inwardly projecting edge 10 of the lips Sa can catch 38 as in Fig. 6.

Figures 7 and 8 show two other variants of a composite rasm profile 2 according to the invention, in which, in this case, one or both, respectively, half-shells 6 are constructed in two parts, with a detachable part 6a. Figures 9 and 10 show an example of a device 16 for applying the method as described above.

In this example, the device 16 comprises two parallel plates 17 one above the other and at a distance from each other, which respectively form the top wall 17a and bottom wall 17b of a tunnel-shaped guide 18 which can be brought together; 15 half-shells 6 and insulator 7 will be guided through them for implementation of the method according to the invention, and this in a feed direction A, which is indicated by an arrow A in figure 9, The side walls of the tunnel-shaped guide 18 are formed by two series of sanding wheels 19 , each on a different side and symmetrically from a median plane M-M' of the tunnel, the mutual distance W between the successive pressure wheels 19 decreasing 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 17b at a distance from each other such that the insulator 7 can be passed through between the support surfaces 13 with a minimum clearance. In the top wall 17a, guide grooves 20 are provided for guiding with a certain clearance the upper edge of the nalf shells & in a direction tangential to the pressure wheels 19 as shown in dashed line in figure 3, In the profiling of the lower supporting surface 13 of the isclator 7 recesses 21 are provided for supporting the half-shells 6 with the grooves 8 straight across the longitudinal edges 12 of the insulator 7. {15 In addition to the supporting surfaces 13, sufficient space is provided | for the elastic movement of the lips 93 when germinating the insulator 7.

The device 16 is furthermore provided with a sand drive, not shown in the figures, for pushing or pulling the half-shells 6 together with the insulator 7 in their longitudinal direction in the feed direction A through the tunnel, for example by means of a windable cable on a winch that runs downstream. of the tunnel has been established.

The use of the device is very simple and as follows.

The hall shells & together with insulator 7 are forced through the tunnel between them.

The outer sides of the half-shells 6 come into contact with the pressure wheels 19, which gradually force the half-shells 6 more and more in the direction of the median plane M-M and of the insulator 7. The pressure wheels 19 exert pressure force F 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 of the tunnel where the insulator 7 may be loose, while in figure 11 the same situation is shown at that 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 ready-to-use composite window profile 2 is obtained that only needs to be at the correct length or can undergo further finishing without it being necessary, however, to further deform the lips 9 of the grooves 8 of the half-shells 6, In Figures 12 and 13 show a slightly modified device having a flat top and bottom wall 17a and 17b, in which case chainmail is used to support and keep the half-shells 6 and the insulator 7 in line during their passage through them. the device 16. To this end, use is made of an outer mold 22 in the form of two U-profiles 23 which, with their openings directed towards each other, are extended between the pressure wheels 19 and which are laterally slidably supported between the top and bottom walls 17a and 175. from the tunnel.

These U-profiles 23 are slid over the half-shells 6 and 2 support the half-shells 6 in a vertical position over the length of the half-shells 6. The loose insulator 7 is supported in an analogous manner in the outer mold 22 by an inner mold 24 with an upper masonry 24a and a lower mold 24b with support surfaces 13 between which the insulator 7 is arranged and which are arranged laterally slidably between the legs of the outer mold 22. The whole of molds 22 and 24 with the half-shells 6 and insulator 7 received therein is then placed between the pressure wheels 19 of the device of figure 13, whereby the U-profiles 23 of the outer mold 22 together with the half-shells 6 are forced towards each other, with the insulator 7 clamped at the end between the half-shells 6 as in figure 13. A variant of a inner mold 24 is shown in figure 1e, in which case the upper mold 24a and the lower mold 24b consist of two parts, each of which can be moved separately laterally in the outside. mold 22 are provided. The drive around the half-shells 6, the insulator 7 and, if necessary, the molds 22 and 24 can be done in any way, for example by a pulling cable that is wound on a winch or because the pressure wheels 19 are designed as pulling wheels 19 with their own drive.

It is clear that instead of pressure wheels 19, voile straight tunnel walls can also be used in Teflon or in other material with a low shear resistance. this should not be regarded as an absolute indication but rather as an indication relative to the figures. The present invention is by no means limited to the exemplary 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,
