Abstract

An extruded section for forming heat-insulated door frames, window frames and the like is composed of a hollow aluminium profile (2, 2') which forms the facade side and constitutes the carrier for all the mechanically loaded fittings, anchorings and the like, and of an essentially non-load-bearing plastic profile (3, 3') which forms the room side and is connected to the hollow aluminium profile (2, 2') by parts, such as grooves and strips, which engage one in the other or one behind the other. In order to achieve, with the same measures, a good heat insulation and a good grip of the profiles on one another, the plastic profile (3, 3') forms, with the hollow aluminium profile, a hollow chamber which is filled with a foamed plastic (12). The foamed-plastic filling, being supported on the two profiles (3, 3' and 2, 2'), fixes and clamps (or braces), and adhesively bonds, said profiles with respect to one another and, furthermore, the foamed-plastic filling engages between or behind the connecting parts of the two profiles (3, 3' and 2, 2') and likewise fixes these with respect to one another and bonds them adhesively. <IMAGE>

Description

"Process for the production of

Profiles and associated composite profile The invention relates to a profile strand according to the preamble of claim 1.

This has certain advantages over such profile strands reached, which either consist of aluminum or just plastic.

The disadvantage here is the still unsatisfactory thermal insulation and in particular the fact that the mechanical hold between aluminum hollow profile and the plastic profile is insufficient. The connection can be justifiable in practice Measures are not made so tight that sliding lengthways between Plastic profile and aluminum hollow profile is definitely avoided, unless one would provide complex screw connections.

The task of the end is seen in a profile strand according to the preamble of claim 1 with one and the same license for both better thermal insulation as well as a perfect, secure hold of both Profiles to care for each other.

The solution to the above problem is initially served by the features of the Characteristic of claim 10 With the same depth of the plastic profile a significantly higher thermal insulation is achieved compared to known arrangements, respectively while maintaining the thermal insulation according to the known prior art the depth of the plastic part is correspondingly smaller. At the same time, with the plastic foam a tensioning of the strips in the grooves or the like and thus an absolutely safe one and a firm hold of the plastic profile on the aluminum hollow profile is achieved.

Both profiles are so tightly clamped together that they are also Do not let them move towards each other when applying force. A profile strand after the invention can therefore without the risk of shifting the profiles to each other as So-called yard goods are bought and processed, e.g. by cutting or at Acklinks for sprout connections of the later joints on a miter6 Finally the plastic foam gives an additional stiffening or stabilizing effect, which is particularly important in the manufacture of window or door frames Meaning can be.

The features of claim 2 include an advantageous design of the cross-section of the plastic profile approximately in the form of a '2U11, which is connected to the essentially smooth surface of the aluminum hollow profile for the purpose of Forming the hollow chamber cooperates.

The features of claim 3 cause an even better hold of the Profiles to each other through the foam.

The features of claim 4 allow a stop between the abutting corners of the plastic profile parts due to the solid Jamming between the plastic profile and the aluminum hollow profile also on its Halt affects. In addition, the aluminum hollow profile parts can also be used in a known manner be held by such corner connections.

The features of claim 5 provide an additional Wärmedåmag in the area of the joint surfaces between the frame and sash frame.

With the features of claim 6, the heat is cross-section very reduced.

With the features of claim 7, the mechanical strength increased at this point without thereby increasing the heat flow.

The features of claim 8 further serve the o.g.

The aim of the invention to achieve the greatest possible thermal insulation when used externally located aluminum hollow profiles.

The invention is also based on the object of the To further improve claims 1 to 8, in particular in its manufacture, its thermal insulation and the cohesion of the parts of the composite profile.

Accordingly, the invention relates to a method according to the preamble of claim 9. For the state of the art, reference is also made to DE-PS 20 27 937 referenced.

When pushing the plastic profile and the aluminum hollow profile together can cause unwanted and pushing together at the interlocking grooves and webs hindering or at least aggravating friction arise. The pushing together of the two profiles respectively. Profile part body is preferably made for their connection will.

But they could also be plugged into one another in the manner of a latching connection. Here, too, the grooves and ridges can be in the way. It should therefore According to the task, first the procedure according to the generic term of the claim 1 to the effect that the two profiles are as light as possible, in particular can be brought into the final operating position without hindering friction, but after joining the desired firm hold between them ensured should be.

Based on the preamble of process claim 9 therefore sees the Invention first the Verfshrenslösungen according to the characterizing features of Claim 9 before. This solves the problem outlined.

With the features of process claim 10 it is achieved that the Do not press the grooves and ridges into one another until as late as possible, i.e.

takes place when the insertion or locking process has already been completed This is particularly recommended when joining profile part bodies with the Features of claim 13 (see below) 9 as in this embodiment of the invention there is a very good press fit of the plastic profile in the aluminum profile, so that in spite of the Dunnflüßsigkeit the plastic compound there is no risk of an unintentional There is exit of the foam approach of this plastic mass at leaks.

However, there are cases conceivable in which the aforementioned risk exists, that the foam build-up emerges through leaks. The Features of process claim 11.

According to this method claim 11 is therefore preferred for profile part body a proceed according to the features of claim 14 (see below).

A preferred embodiment of the invention is characterized by the features of entitlement 12 given. Their effect is reinforced by that the profiles are designed in accordance with the subject claim 13 already mentioned above are.

As mentioned, the invention is also defined by the method claims, in particular claim 11 in conjunction with the features of the counterstana claim 14 executable. In this case, no special mechanical measures are required for compressing the walls or legs of the plastic profile.

On the other hand, the pressing force between the grooves and webs is here not be as large as in the previously explained preferred embodiment of Invention To further solve the problem according to the invention, namely To create a composite profile with excellent thermal insulation are in further training the features of claim 15 proposed.

This ensures that that part of the aluminum hollow profile which was previously completely free in the space formed by the plastic profiles and the sealing lip is no longer used as a discharge surface for undesired transmission into this room has an effect. The plastic web completely covers this aluminum surface, with only a very small aluminum part remaining as the active surface. Furthermore, only a single sealing lip acting as a center seal is required to seal the profiles at the point of separation. With the preferred embodiment of the claim it is achieved that, because of the closing radius of the sash pivot axis when the sash frame is closed, the stop web with the roll-off lug e with prestressed sealing lip rises perfectly into its end position. The feature of claim 16 also serves as a further development Although the radiating surface of the remaining aluminum bar is somewhat enlarged, this stabilizes the plastic cover bar.

Another advantageous embodiment of the invention is claimed 17 suggested. The double support of the plastic bar achieved in this way is especially advantageous because the cover web serves as an attachment point for Fitting parts are used, which are particularly solid and due to the inventive design are held in a stable manner.

A particularly inventive development of the composite profile is characterized in claim 18. This training enables even those between The cavity formed by the cover web and the aluminum profile is filled with foam. This will on the one hand a further stabilization and on the other hand an even better thermal insulation achieved.

To ensure a particularly stable arrangement of fittings on the plastic profile to enable the development according to claim 21 is proposed.

The level arrangement of the separating web and the cover web enables the exact fitting of a fitting part at this level, so that a flush Connection and a stable introduction of force is possible.

To prevent water ingress, especially in windows and the like in to prevent the gap between the frame and sash profile, respectively. that by wind pressure Being able to drain water that has penetrated there becomes the combination of features proposed according to claim 22.

In order to further create greater security against creeping water, the development according to claim 25 is proposed.

The embodiment according to claim 24 is preferred.

Thus a window created with the composite profiles according to the invention can be properly opened and closed while keeping the space between If the frame and sash profile can be made as narrow as possible, it is necessary to to keep the outer drip nose as short as possible, as this occurs when the window is pivoted otherwise it would bump against the fittings of the frame profiles, the short drip nose however, it is only suitable to a limited extent9 to divert water entering through wind pressure A second drip nose, which is considerably more secure, is achieved longer than the first one can and should be without this when pivoting the window with the hardware components mentioned above of the frame part collides. If all the protruding parts of the casement frame on one around the sash pivot axis drawn imaginary circle, there is a collision with the sealing lip and the Besehlagteile of the frame profile excluded if this circle is slightly smaller than the distance of the wing pivot axis from the opposite frame part is.

In order to provide stable support for fittings that are otherwise not load-bearing To enable the EunststofSprofil, is the combination of features according to claim 25 advantageous.

The longitudinal groove also serves as a centering groove for the holes the corresponding fastening screws.

The feature also serves to hold the fittings in a stable manner of claim 26.

To avoid unwanted radiation in the aluminum frame or To largely exclude the wing profile, the feature of claim 27 is provided.

Furthermore, to improve the insulation in this area Combination of features according to Claim 28 intended. In the lower and In the upper area of a window, the gutter is advantageously perforated to prevent condensation can drain and an effective glass rebate ventilation prescribed by the glass industry to evaporate the condensation water is possible.

In order to achieve the greatest possible coverage of the To achieve aluminum profile, the feature according to claim 29 is proposed.

Embodiments of the invention are based on profiles for window or door frame explained below and shown in the drawing.

However, it can also be used in other cases in which a Profile strand composed of an aluminum hollow profile and a plastic profile is used, e.g. on cold stores or facades, in the drawing shows: Fig. 1 shows a strand-shaped profile according to the invention in cross section, FIG. 2 the two Profile part body of an embodiment according to the invention without plastic foam and also in cross section, FIG. 3 shows a further exemplary embodiment of two profile part bodies according to the invention in cross section and without an elastomer foam D, FIG. 4 a Combination of a casement and a window frame in section 9 Fig. 5 a Variant as seen in FIG. 4, FIG. 6 shows a window construction made of thermally insulated Composite profiles in view, 7 shows a detail of FIG. 6 in the Section Vil-Vil of this figure, FIG. 8 a further detail in section VIII-VIII 6, 9 shows a further detail in section IX-IX of FIGS. 6, 10 the corner mounting of a window with fittings in section, FIG. 11 is a cross section frame through frame and sash on the handle side and Fig. 12 a corresponding Section through the anchoring side in a modified cross-sectional shape.

Profile 1 consists of Big. 1 to 10 from one made of aluminum, in cross section box-shaped profile part body 2 and one made of plastic Profile part body 3, which is approximately U-shaped in cross section. In grooves 4 of the profile part body 2, webs 5 of the profile part body 3 engage.

There is between the webs 5 and the surface facing them 6 of the profile part body 2 a gap 7. On the other hand, the webs 5 lie on the groove walls 4 does 2. The cohesion of the two profile part bodies 2, 3 is ensured by a plastic foam 8 causes, which is located in the hollow chamber 12, on the one hand by the two Legs or side walls 9 of the plastic profile part body 3 and its base wall 10 and on the other hand from the wall 11 of the aluminum existing Profile part body 2 is formed.

With the expansion of the foam 8, the two profile part bodies 2, 3 not only glued together but also clamped, with the help of Grooves 4, 4 "'and the webs 5. This is further supported by the fact that the plastic foam 8 enters the gaps 7 between the webs 5 and the surface 6 of the wall 11. This arises at the abutment surface between the webs 5 and the groove walls 4 '' ' a dry and very high friction, which in connection with the expansion force of the Foam 8 ensures the secure hold of the two profile part bodies on each other. The grooves and webs can also be designed differently. The webs can also be on the aluminum profile part body 2 and the grooves on the plastic profile part body 3 are located.

In the two exemplary embodiments according to FIGS. 2 and 3, it is ensured that the legs or walls 9 of the plastic profile part body having the webs 5 3 for the respectively. during the insertion of the plastic profile part body 3 in the Aluminum profile part body 2, or during the latching of the two profile part bodies 2 and 3 with each other a movement or displacement inward to the hollow chamber 12 or that they assume this position by themselves. For locking measure up the legs of the plastic professional body are compressed so far be or converge, e.g. as described below, that the plastic profile part body into the aluminum profile body from below (based on the illustration in the associated drawing) can be used, with) # possibly snapping the Stege in the SOUTH takes place. Then the legs of the plastic profile part body relieved (if pressure was previously exerted) and the plastic insulating compound made to expand.

As a result, the legs separate and snap with their webs into the grooves of the aluminum profile part body.

In the embodiment of FIG. 2, this movement takes place respectively. Swivel of the side walls 9 by an externally applied force according to the arrows 13. In the case of connecting both profile part bodies by means of insertion, e.g. not shown in the drawing and under a corresponding compressive force standing roller sets can be provided, which are located shortly before the entry point of the plastic profile part body3 are located in the aluminum profile part body 2.

The side walls 9 here take the one shown in dash-dotted lines Position 9 'a. It can be seen that herewith the friction between the webs 5 and the grooves 4 is reduced to an insignificant level. Since the Kunststoffprofii is compressed at the point of entry into the aluminum profile, but afterwards jumps apart again and then again causes friction, becomes friction The further you have pushed the two profiles together, the greater the distance. this can prevent them from being pushed together under unfavorable circumstances. Therefore appears it is recommended, respectively. it may even be necessary to use the role sets via the provide the entire length of the aluminum profile, so that they protrude from this Also press together parts of the walls of the plastic profile that have already been inserted can. Another way to solve this problem is to use the plastic profile to grasp along its entire length with pliers on the wall parts, which ones too protrude from the aluminum profile when pushed in, these walls with means to squeeze the pliers together and only after the two have been pushed together completely Profiles freely to give. The elasticity of the plastic of the profile part body 3 and the cross-section point 14 at the foot of the side walls 9 are dimensioned and dimensioned so that on the one hand the explained Schwenkm movement of the side walls 9 around their base 14 B; is possible, including a backswing after Elimination of the force 13 in the previously assumed position, but that on the other hand the Cross section 14 is not damaged.

This also applies mutatis mutandis to the execution example according to FIG. 3.

During the joining of the two profile part bodies 2, 3, plastic compound is formed poured into the hollow chamber 12. This expandable plastic mass falls in the At the time of their introduction, the cavity available in the chamber only at one point small part, e.g. a quarter or less. Only after their introduction it begins to expand until it finally forms the hollow chamber and also the column completely fills out. A thin, expandable insulating compound can be used which are initially achievable in all of their volume enlargement without pressure Rooms and niches, i.e. also runs into column 7 and only at the end of the Reaction phase builds up a pressure.

This is particularly recommended in an embodiment according to FIG. 2, in which the legs 9 diverge outwards in the unloaded state (see above).

But you could also use an expandable plastic insulating compound, which already existed before the Expansion is or becomes thick, i.e. either is introduced already viscous or by the reaction before expansion assumes this state and therefore only in this viscous consistency the existing one Fills the cavity.

Because the plastic mass is only bad because of its thickness flows, fine slits etc. are no longer or only partially filled will. This avoids the risk that the expanding foam plastic exits through small gaps etc. The plastic profile part body can thus initially sit loosely in the aluminum profile part body, so that the use of such, even before the expansion of viscous plastic, especially for the connection of profile part bodies according to the embodiment to be explained in more detail below 3 recommends in which the legs 9 of the plastic profile part body z '; # grows converge inwards.

The interlocking of the webs 5 and the grooves 4 indicated in FIG. 3 is sufficient already as a seal for the already viscous expanding foam, which then, with further increasing pressure, the legs 9 of the plastic profile part body in the final shape of FIG. 1 expresses.

As an example of plastic insulation compounds that here can be used, may be mentioned: a polyurethane foam, a polyisocyanurate foam, and foamed, unsaturated polyester resins.

A polyurethane foam and polyisocyanurate foam are by appropriate Additives can be set to be both thin and thick. The polyester resins mentioned are naturally thicker.

As already mentioned, the pressure of the expanding mass 8 pushes the converging inwardly during the pushing together due to the force 13 (see FIG. 2) Walls 9 'outwards into the position according to FIG. 1.

This pressure force is in the preferred embodiment of Fig. 2 still supported by the fact that the walls 9 of the profile part body 3 in the unloaded position, as already mentioned, an outward divergence # de Location is such that the outer edges 5 'of the webs 5 from each other a larger Have a distance than the inner edges 4 'of the grooves 4 ~ of the profile part body 2.

This is shown in Fig. 2 with solid lines. As soon as on the walls 9 respectively. 9 'no more force is exerted in accordance with arrow 13, pushes the due the aforementioned shaping resulting outwardly directed prestress the webs 5 with a corresponding force in the grooves 4, which is the contact pressure superimposed due to the expanding plastic.

In the embodiment of Fig. 3 is made of plastic Profile part body 3 shaped so that the distance between the web outer edges 5 '' is smaller than the distance between the r. # inside edges 4 ". In the present example, in which the walls 9 run parallel to each other in the normal position (see Fig. 1), this means that the walls 9 converge towards the hollow chamber 12. If required, can also here - another inwardly directed compressive force according to arrow 13 in Fig. 2 are applied. The aim here is also to reduce friction when pushing them together or locking of the profile part body 2, 3 is achieved.

The expanding foam mass 8 then presses the walls 9 into the Position according to FIG. 1, in which they firmly engage with their webs 5 in the grooves 4 and are braced by the foaming jerk.

The window constructions made of thermally insulated composite profiles according to the exemplary embodiments of FIGS. 4 to 10 described below exist in essential from the profile strand 21, respectively the fixed frame part. profile forms and a profile strand 24 in the form of the sash 9 bezvO profile that is pivotally attached to the fixed frame part. The profile strand 21 is from a box-shaped aluminum hollow profile 22 and an approximately U-shaped profiled Plastic profile 23 composed, with the legs and the base of the U-shaped plastic profile 23 and from one side of the aluminum hollow profile 22 bounded chamber for the purpose = composite formation is foamed. The profile strand 24 of the sash is designed in an equivalent manner.

The aluminum profile is there with 25, the plastic profile with the Reference numeral 26 denotes. It is in comparison with the exemplary embodiments 1 to 3 it can be seen that the profile strands 21 and 24 correspond to the profile 1, the aluminum hollow profiles 22, 25 the aluminum profile part body 2 and the plastic profiles 23, 26 correspond to the plastic profile part body 3, and, if desired, also so can be designed and assembled.

On the side of the plastic profile facing the profile strand 21 26, a cover web 61 is formed on this plastic profile 26, which the aluminum hollow profile 25 overlaps up to a stop web 51 formed thereon.

Against this stop web 51 lies when the window is closed Sealing lip 201 attached to the aluminum hollow profile 22 of the frame profile.

The stop web 51 strives approximately at right angles from the aluminum hollow profile 25 and is angled slightly towards the plastic profile 26 at the end, see above that a flat contact of the sealing lip 201 reached will. On his At its outermost end, the Äxisch Lxgsteg 51 has a roll-off nose 52.

In the variant according to FIG. 4, the web part 53 is provided with a further molded at right angles to the profile side wall strutting Ai ## änklung 55 provided, one groove as a receptacle for a corresponding approximately T-shaped insertion web 63 of the plastic profile 26 forms.

Dcr insertion web is an extension of a support web 62. For The purpose of the composite formation is the plastic profile 26 only by means of the Slide-in web 63 and the strip 27 located on the other profile leg on the aluminum hollow profile 25 held. The chamber to be foamed extends from one strip 27 to to slide-in web 63.

In the embodiments of FIGS. 5 to 10, starting from Abrol1nase 52 formed on the stop web 51 a short web part 53, which opposite the rolling nose 52 is set back and runs parallel to the profile side wall.

The cover web 61 is arranged in one plane with the web part 53 and engages under the web part 53 with a bend and with a right-angled bend to the profile side wall and while forming the support web 62, the web part 51.

The support web 62 is supported on the one hand on the web part 53 and on the other hand on the profile side wall.

Preferably in the lower area of the casement 24 has a variant According to FIG. 5, the cover web 61 has condensation drainage holes 64 (see FIG. 8).

The base of the plastic profile 26 on the room side is the same like the base of the plastic profile 23 covered by a hollow chamber 29.

The hollow chamber 29 of the plastic profile comprises two chambers 91, 92, one of which (91) covers the front side of the profile space to be foamed and runs up to the alignment with the cover web 61.

The second chamber 92 has an uninterrupted one with the first chamber 91 Front face, but is through a separating web 65, the level of the cover web 61 is arranged, separated from the first chamber 91.

The web of the hollow chamber 92 forming the inner surface is about the thickness a sealing strip 66 set back with respect to the separating web 67. So that runs facing the room side face of the profile 23 in a plane to the inner one End face of the hollow chamber ~ 91. The hollow chambers can be designed in this way be, that they bulge the respective plastic profile to the room side, which under certain circumstances could be caused by the foaming pressure.

On the facade side of the window formed from the composite profiles the frame profile cl forms a labyrinth-like manner with the sash profile 24 at the parting line Sealing point 41.

On the sash profile 24 is immediately next to the sealing point 41 a drip nose 54 is integrally formed.

At a distance from this drip nose, a second drip nose 56 is profiled between the drip nose 54 and the stop web 51. This drip nose 56 has a greater web height than the drip nose 54. The two drip noses and the lie at the pivotable sash frame 24 with their end points on a circle drawn around the sash pivot axis as the central axis, which is slightly smaller than the distance circle from the fitting parts of the profile strand 21 necessary for pivoting 0 As can be seen from Fig. 8, is between the drip noses 54 and 56 in A condensation water passage 64 is formed in the lower window area. The backwater is finally led to the outside through a further condensate outlet opening in an aluminum strip pushed over (Fig. 8).

According to FIG. 10, a leg 68 of the plastic hollow profile 29 has a reinforcement 69 in the center, dle containing a longitudinal groove 70 on its outside. (Fig. 5) This reinforcement is used to screw in fastening screws for Fitting parts and the longitudinal groove serves as a centering groove for the holes in the Fastening screws.

At right angles, webs 71, 72 strive from the leg 68, the stops 73, 74 form a fitting part, as can also be seen from FIG.

In the glass rebate of the profile is a profile strip 80 made of plastic arranged that the side wall of the aluminum profile 25 against the edge of the glass pane shields (see in particular Fig. 5). The profile strip 80 has support webs 81, which are supported on the aluminum hollow profile 25. Above that as a Gauwasser runoff perforated aluminum hollow profile area 57 between the drip noses 54 and 56 is the profile strip 80 is lowered to form a channel 82 towards the aluminum hollow profile 25.

The channel 82 is BEZW as a condensate outlet.

Glass rebate ventilation perforated in the lower and upper window area. This can again be seen from FIGS. 8 and 9.

Finally, the sealing lip 201 is designed in its foot area so that that the area of the aluminum hollow profile 22 is covered, which is within the the plastic profiles 23 and 26 and the sealing lip 201 is surrounding space.

As far as in the Äusfüurungsbeispielen FIGS. 11 and 12 the same or the same components are provided as in the previous exemplary embodiments, the same reference numbers have been used for this. In the embodiment of Fig. 11 and 12 are window frames and casement frames also each made of profile strands formed, the profile strand 1 of the Ra Dndrahmenq made of an aluminum hollow profile 2 and a plastic profile 3, as well as the casement 1 'also made of an aluminum hollow profile 2 'and a plastic profile 3'.

Here, too, from the plastic profile, which is approximately U-shaped in cross-section and the facing surface of the aluminum hollow profile is formed hollow chamber 12 with a plastic foam, preferably a closed-cell polyurethane rigid foam foamed, which at the same time in the longitudinal direction of the plastic profile extending strips 5 (see Figure 11) of the plastic profile engages behind. the Bars 5 are inserted into grooves 4 of the aluminum hollow profile or with a snap action depressed.

The strips are made by the pressure of the expanding plastic foam pressed against the stop surface 4 '' 'from which the strips 5 engaging behind Web 2 'of the aluminum profile is formed. This corresponds to the plastic filled gap 4 a corresponding air gap 7 on the other side of the aluminum web 2 '. By pressing the plastic strip 5 against the aluminum strips or webs 2 'there is a secure jamming of the intervening plastic profile # with the Aluminum hollow profile, This is done in the same way for profiles 2 'and 3 '. It can be seen that the jamming of the two profiles together by the Rigid plastic foam does not affect the profile cross-sectional shapes of the present exemplary embodiment is limited (see also Figs. 1 to 10).

A separate hollow chamber 18 can be provided in the plastic profile which turns it into a plastic hollow profile.

After cutting the profile strand is mitred in the chambers 18 butting against one another along the miter surface inserted a corner bracket, which connects the plastic profiles to one another at the miter surface and is straight the sensitive plastic profiles at this corner connection the necessary mechanical Stop there.

Similar corner angles could be provided and inserted into the cavities of the aluminum hollow profiles be plugged in.

The corner angles are dimensioned so that they have a clamping or spreading effect BEZW into the chambers 18 of the plastic profiles. Cavities in the aluminum profiles fuel gas are. In this context it should be mentioned that the aluminum hollow profile BEZW. the frame formed from this is statically uninterrupted and over its entire 4cross section wears.

All mechanically stressed parts or brackets, like handles. Tapes, wall anchors, etc. must be attached, while the #plastic hollow profile respectively the frame formed from this with plastic foam essentially only has the heat insulation effect. The plastic profile of the window frame only bears the pressure the seal. The plastic profile of the casement carries this sealing pressure and as the tensile force, the wind pressure on the pane, which is transmitted from the glazing bead will. The plastic profiles are therefore not load-bearing, with the exception of the aforementioned Forces the but compared to those to be recorded by the aluminum hollow profile Forces (weight and wind suction) are of secondary importance.

Fig. 11 shows that between the profile strand 1 for the frame and the profile strand 1 'for the casement each cooperating and circumferential Dichtle'sen 201 on the mutually facing sides of both the plastic profiles 3 and 3 ', as well as the aluminum profiles 2 and 2' can be provided.

This also provides thermal insulation for the profile in this area strands approximated thermal insulation achieved.

If metallic connecting parts, such as screws or the like are provided, the heat transfer will be reduced as much as possible there. For example, FIG. 12 shows the articulation of the flying frame 1 'on the frame 1 by means of bands 83, these bands being fastened to the aluminum profile 2 'by screws 85 of the sash 1 'are attached.

For this purpose, the screw shafts are from a heat-insulating spacer, here in the form of a plastic jacket 84, which is located between the aluminum hollow profile and the part 83 to be fastened is supported. So it is only the relatively small ones Cross-section of the screw shafts a thermal bridge. The thermally insulating spacer can also be designed differently, e.g. located on the side of the screws.

In a similar way, according to FIG. 11, it is gripseitiq in the aluminum hollow profile 2 'of the casement 1', a fastening rod 15 for a handle 16 is provided and surrounded by a plastic jacket 17 which extends between the corresponding Wall 11 of the aluminum hollow profile and the opposite side of the handle and at the same time surrounds the rod 15.

This increases the mechanical strength of this breakthrough and at the same time the heat transferring cross-section is kept very small.

(Fig. 12) Also the space 2U in the glass rebate and the space 79 / behind the Glazing beads can be filled with heat-insulating material (e.g. plastic foam) be.

All new items disclosed in the description and / or drawing and combination features are considered essential to the invention.
