Description

The invention relates to an extruded window or door hollow chamber profile according to the preamble of claim 1. Such a hollow chamber profile can preferably already have an integrated reinforcement ex works and comprises at least one fastening area for fastening the hollow chamber profile to or for connecting the hollow chamber profile to an external component , which fastening area is designed and provided for receiving a fastening means profiled at the edge. In the fastening area, the hollow chamber profile has at least one fastening channel, which is oriented perpendicular to a longitudinal direction of extrusion of the hollow chamber profile. The fastening channel has a channel longitudinal axis, is closed at its ends perpendicular to the channel longitudinal axis by an outer wall of the hollow chamber profile and is laterally delimited parallel to the channel longitudinal axis by channel side walls.

The invention also relates with claim 9 to a system made up of an extruded window or door hollow chamber profile according to the invention and at least one additional, separate profile element.

With claim 14, the invention also relates to a system consisting of an extruded window or door hollow chamber profile according to the invention, optionally at least one additional, separate profile element, and at least one fastening means profiled on the edge, preferably a screw.

With claim 15, the invention further relates to a frame for a door or a window, which is formed from several sections of hollow chamber profiles according to the invention that are connected to one another in connection areas, preferably welded.

A generic hollow profile is, for example, from DE 10 2020 108 412.9 , the EP 2 079 895 B1 or the DE 43 38 181 C1 known.

Such hollow chamber profiles can be used in particular for the production of blind frames. A window frame is that part of a window or door that is immovably fixed to the structure or generally to an "external component" (in contrast to the regularly movable sash (frame)).

The hollow chamber profiles are usually connected to the masonry (reveal) of the building or to any other external components at defined intervals using assembly or fastening means, such as spacer assembly screws.

Known on the market are special, high blind frames in so-called closed or open designs (see figures 1 and 2 ). These are designed as separate items (manufactured on different tools), so that a window manufacturer must decide in advance on one of the two designs and/or ensure double stocks.

Each of these previously known solutions has specific advantages and disadvantages. This is the case with closed, high blind frames figure 1 , which regularly have two reinforcement chambers arranged one above the other, the screw connection in the upper reinforcement chamber is only possible with corresponding additional effort (e.g. milling out the window frame foot area). With the open window frame according to figure 2 this additional effort is omitted; However, a deep undercut occurs when the window is installed, which requires special installation and results in a large free distance between the installation screw and the structure, which has a negative effect on the stability that can be achieved.

There is a need for a hollow chamber profile of the type mentioned that enables both processing and assembly options in one component and thereby reduces the variety of profiles for the window manufacturer without having to make the additional effort mentioned or make compromises in stability. The invention is therefore based on the object of further developing a hollow chamber profile of the type mentioned at the outset in such a way that both processing and assembly options are made possible with the same profile and the profile variety of the window manufacturer is thereby reduced without having to make the additional effort mentioned or make compromises in terms of stability got to.

The object is achieved according to the invention by an extruded window or door hollow chamber profile with the features of claim 1, by a system with the features of claim 9 or 14 and by a frame with the features of claim 15.

Advantageous developments of the subject of the invention are defined in the dependent claims.

According to the invention, an extruded window or door hollow chamber profile, preferably with reinforcement integrated ex works, with at least one fastening area for fastening the hollow chamber profile to or for connecting the hollow chamber profile to an external component, in particular to masonry (structure), which fastening area is to be accommodated a fastening means profiled on the edge is formed and provided, which hollow chamber profile has at least one fastening channel in the fastening area, which is oriented perpendicularly to a longitudinal direction of extrusion of the hollow chamber profile, which fastening channel has a longitudinal channel axis, at its ends perpendicular to the longitudinal channel axis through an outer wall in each case of the hollow chamber profile is closed and parallel to the longitudinal axis of the channel is laterally delimited by channel side walls, characterized in that the hollow chamber profile in the area of the assembled state of the hollow chamber profile The outer wall facing or to be faced to the external component has at least two projections, which extend at a distance from and parallel to the longitudinal channel axis and which define between them an outwardly opening, clear free space which extends parallel to the longitudinal channel axis over the fastening channel extends beyond. The hollow chamber profile thus enables the simple production of an open window frame, which makes it possible to introduce reinforcement (eg for a post connection) in the area of the free space without further milling or the like.

In a system according to the invention consisting of an extruded window or door hollow chamber profile according to the invention and at least one additional, separate profile element, which profile element has dimensions in relation to its cross section that correspond to the corresponding dimensions of the free space, so that the profile element can be accommodated in the free space in its assembled state or is recorded. The profile element is also referred to below as a "sole bench". It can be made of a plastic such as PVC. A special design of the opening (the free space) can be achieved within the scope of configurations described below that the opening (the free space) can be closed by the sill, in order to enable the advantages of a closed window frame.

In a system according to the invention consisting of a hollow chamber profile according to the invention, preferably an additional, separate profile element and at least one fastening means profiled at the edge, preferably a screw, it is provided that the fastening means along the longitudinal channel axis into the fastening channel or, in the case of a corresponding further development, into several partial fastening channels is introduced, wherein the external component is arranged or is to be arranged in an extension of the longitudinal axis of the channel; and/or that the fastening means is introduced transversely to the longitudinal axis of the channel in the fastening channel or, in the case of a corresponding development, in at least one of the partial fastening channels, with the external component being laterally spaced from the longitudinal axis of the channel in the area of one of the two outer walls that are different Front side of the hollow chamber profile is arranged or is to be arranged; wherein an outer diameter of the fastening means is preferably larger than a clear cross section of the partial fastening channels or of the at least one of the partial fastening channels; optionally wherein the fastener penetrates the profile element.

In a frame according to the invention for a door or a window, which is formed from several sections of hollow chamber profiles according to the invention that are connected, preferably welded, to one another in connection areas, it is provided that in at least one of the connection areas a preferably metal connection element, preferably a connection bracket, is split into two with each other connected hollow chamber profile sections in the area of the respective fastening channel is introduced; and/or that a preferably metallic reinforcement element is inserted in at least one hollow chamber profile section, with a corresponding further development preferably in the at least one intermediate region or in at least one of the intermediate regions; and/or in which an additional, separate profile element is inserted into the free space of at least one hollow chamber profile section.

Window profiles known on the market or generally hollow chamber profiles of the type mentioned have to be reinforced accordingly, depending on the requirements at hand and the loads to be expected. Conventional window profiles have specially dimensioned hollow chambers. Metal profiles are inserted and screwed into these chambers to increase the stability of the window or door. Such chambers are referred to as reinforcement chambers. Although only windows were mentioned above, the same problem also applies to door profiles, which is why the following is simply referred to as “hollow chamber profiles” or “profiles” for short.

Alternatively, fiber-reinforced materials or thermally separated metal reinforcements are increasingly being used, which can already be integrated into the profile at the factory.

Metals have high thermal conductivity. The reinforcements therefore lead to a deterioration in the thermal insulation within the structure. New constructions with fiber-reinforced components or with thermally separated stiffeners can improve the thermal insulation considerably. Due to the strongly varying loads depending on the installation location and application, a precise dimensioning of the reinforcements integrated in the profile ex works is very imprecise. The stiffening is therefore often oversized or undersized depending on the application. In some applications, additional metal reinforcement is therefore advantageous or even necessary.

With conventional solutions, the screw penetrates the reinforcement chamber so that the profile is attached to the masonry via the reinforcement. In the case of fiber-reinforced profiles, the required screw retention in the profile is achieved with the help of screw channels, for example.

However, the provision of a continuous screw channel, in particular according to the prior art mentioned above, has the fundamental disadvantage that no additional reinforcement can be used in this area. As a result, the area of application of correspondingly designed window frame profiles is severely limited.

In some constructions, neighboring hollow chambers of the profile can then be reinforced. However, with such a stiffening of adjacent hollow chambers, the drilling and screwing positions have to be offset in order to connect the stiffening to the masonry. This is difficult to implement in terms of control and production technology.

In summary, it can be said that conventional window profiles with subsequent metal reinforcement have the disadvantages of poor thermal insulation and high weight. Window profiles with factory-integrated reinforcement are difficult to dimension; additional reinforcement is only possible with difficulty, in particular there is no uniform screw position with additional reinforcement. Depending on the application and load, window or door constructions have to be dimensioned differently today. When using steel reinforcements, an offset mounting axis is therefore disadvantageously necessary.

A particularly advantageous development of the hollow chamber profile according to the invention therefore provides that the fastening channel is divided into at least two partial fastening channels, which partial fastening channels are spaced apart from one another in the direction of the longitudinal channel axis by at least one intermediate region, with the channel side walls preferably being in the intermediate region have a greater distance from one another than in a region of the partial fastening channels.

The fastening channel can de facto be reduced to a single partial fastening channel or a single screw chamber. Ultimately, all that matters is that there is at least one section along the fastening channel in which a fastening screw or the like with the lateral channel walls in Interaction can occur in order to achieve a sufficient fastening effect. In the way in which the term "attachment channel" is used here, it is not necessary for it to be continuous over its entire length for the interaction mentioned.

The proposed construction is designed in such a way that the screw retention in the profile is sufficiently dimensioned for standard loads even without additional reinforcement due to the partial fastening channels or screw chambers provided according to the invention. A comparable level of rigidity to solutions with a continuous screw channel could be determined, particularly in the case of assembly means (fastening screws) subjected to transverse forces. Lateral forces result, for example, from loads that typically occur on the window due to wind loads.

For special loads, such as when using fall protection or a French balcony, a (metallic) reinforcement can also be pushed into the profile in the intermediate area mentioned. In this case, the mounting holes advantageously remain on the same axis and position.

The screw connection then penetrates the accumulations of material in the profile, which are preferably present in the area of the partial attachment channels or screw chambers (or formed by the screw chambers themselves), and the stiffening in the same way. In areas of application where metal reinforcement is required, the profile can be selectively and partially stiffened without having to change the production process for drilling and screwing. The reinforcement effect can thus be dimensioned particularly efficiently.

The term “screw chamber” preferably means that the relevant chambers (in the case of a cross section through the profile) are surrounded or enclosed on all sides by profile material (webs). The screw chambers therefore already represent accumulations of material in the profile, which increases stability.

A special development, which has already been mentioned above, of the hollow chamber profile according to the invention provides that the channel side walls in have a greater distance from one another in the intermediate region than in a region of the partial fastening channels. In this way, sufficient space can be created in the intermediate area for introducing a suitably dimensioned reinforcement profile. In particular, the channel side walls in the intermediate area recede at least to such an extent that there is no longer any interaction with the assembly/fastening means.

In this context, a special further development of the hollow chamber profile according to the invention provides that the intermediate region is designed as a reinforcement chamber for receiving a preferably metallic reinforcement.

A particularly advantageous further development of the hollow chamber profile according to the invention provides that at least one of the partial fastening channels forms a channel projection that is locally limited in cross section in the region of the outer outer wall. This channel projection, which serves as a screw chamber, can thus be arranged outside of the aforesaid reinforcement chamber in the free space, so that it does not impede the introduction of the aforesaid reinforcement.

Another development of the hollow chamber profile according to the invention provides that an accumulation of material or a thickening, in particular of the relevant outer wall, is provided within the partial fastening channels, preferably on at least one of the two outer walls. As a result, the holding effect already mentioned can be further improved. However, the partial fastening channels mentioned also represent certain accumulations of material, as has already been pointed out. This effect can be further improved by the additional material accumulations or thickenings mentioned

In yet another further development of the hollow chamber profile according to the invention, it is provided that the channel side walls have projections on their inner side, which delimits at least one of the partial fastening channels. Such projections can mechanically interact with a fastener introduced into the channel to improve the fastening effect.

In order to further increase this effect, with a corresponding further development of the hollow chamber profile according to the invention, it can be provided that a maximum clear distance is provided between projections that emanate from different channel side walls in a transverse direction transverse to the longitudinal channel axis, which maximum clear distance is preferably 2 mm does not exceed; and/or that a maximum distance is provided between two adjacent projections in a longitudinal direction along the longitudinal axis of the channel, which maximum distance is preferably 2 mm or less; and/or that a maximum distance of preferably 2 mm or less is provided between a projection and a channel side wall opposite the projection. In this way it can be ensured, in particular, that a fastening means introduced into the channel interacts with the projections mentioned. From the applicant's point of view, the specified values have proven to be particularly suitable.

In this context, it can also be provided that projections originating from different channel side walls are offset in the longitudinal direction along the channel longitudinal axis or are arranged at the same height. This allows the fastening effect to be adapted to different requirements.

In yet another development of the hollow chamber profile according to the invention, it can be provided that at least some of the projections extend at an angle with respect to the relevant channel side walls, which angle is preferably either 90° or deviates from 90° and is preferably between 30° and 60° , most preferably 45°, with projections preferably arranged at the same height having the same angle. This too can contribute to an improved fastening effect.

In an extremely advantageous development of the hollow chamber profile according to the invention, it is provided that the intermediate area is designed as a reinforcement chamber for receiving a preferably metallic reinforcement. The particular advantages of such an embodiment have already been pointed out in detail above. In particular, this can mean that the intermediate area is dimensioned to be sufficiently large in order to be able to accommodate a statically effective reinforcement therein. This may imply that in In the direction of the longitudinal axis of the channel, there is a clear distance between the part-fastening channels or screw chambers, or that the channel side walls in the intermediate area are set back significantly compared to the part-fastening channels.

In practice, the armor chamber can have typical dimensions of between 20 and 40 mm in height and width. The screw chambers can have a width of preferably 6 to 8 mm (chamber clearance) and a height of 3 to 10 mm.

In yet another development of the hollow chamber profile according to the invention, it can be provided that the channel side walls in the area of at least one partial fastening channel are laterally supported at least on one side, preferably on both sides, transverse to the longitudinal direction of extrusion. This improves the stability of the partial fastening channels when introducing a fastening means and thus increases the holding effect.

In yet another development of the hollow chamber profile according to the invention, it can be provided that at least one channel side wall is supported at an angle of 90 degrees with respect to the channel longitudinal axis. In practice, this results in a particularly good stabilization effect.

Additionally or alternatively, in another development of the hollow chamber profile according to the invention, it can also be provided that at least one side wall of the duct is supported at an angle deviating from 90 degrees with respect to the longitudinal axis of the duct. In particular, this can have advantages with regard to the required use of material in the production of the hollow chamber profile.

Another advantageous development of the hollow chamber profile according to the invention provides that at least one partial fastening channel is designed as an attachment to a continuous crosspiece of the hollow chamber profile, preferably below or outside the relevant crosspiece in the assembly direction. Such a configuration has proven to be particularly robust in practice. In addition, through the crossbar in question thermally effective additional insulating chamber can be created within the profile, which brings corresponding energetic advantages.

In a development of the hollow chamber profile according to the invention, it can also be provided that the fastening channel is at least partially filled with a solid or pasty material, preferably with a thermally active insulating material and/or a fastening material, in particular an insulating foam or injection mortar. As a result, both the thermal insulating properties and the holding effect can be further improved.

In another development of the hollow chamber profile according to the invention, it is provided that at least one of the projections has at least one hollow chamber. As a result, the stability of longer projections in particular can also be increased.

In yet another further development of the hollow chamber profile according to the invention, it is provided that at least one terminal web is arranged on at least one of the projections, preferably at least two terminal webs. Such webs can form an advantageous form-fitting connection with insulating or fastening material at the interface to the structure.

In yet another further development of the hollow chamber profile according to the invention, it is provided that at least one of the projections has at least one further projection on its inner side facing the free space, preferably a projection with a triangular cross section. This projection can serve as a stiffener for the first-mentioned projections, as a protection against loss and/or as a spacer for the profile element used (sole bench). The projection preferably serves to prevent loss of an optionally (eg as part of a development of a system according to the invention or alternatively) in the back of the frame, ie on the side facing the structure arranged or to be arranged insulation element, eg made of Styrofoam. The insulating element can in particular be provided instead of the profile element. However, said projection can also serve as a latching projection for latching a correspondingly designed separate profile element in a system according to the invention. Of course, both types of projections can also be provided at the same time, then preferably at different positions on the inside mentioned.

A particularly advantageous further development of the hollow chamber profile according to the invention provides that there is another such (locking) projection in the area of the free space in relation to the mentioned (locking) projection in order to improve the holding effect. This further (locking) projection is preferably arranged on that partial fastening channel which is designed as a shoulder on a continuous crossbar of the hollow chamber profile. However, the invention is in no way restricted to such a special arrangement of the further (locking) projection.

In an advantageous development of the hollow chamber profile according to the invention, it is provided that at least one of the projections has a section on its inner side facing the free space that is oriented obliquely with respect to the longitudinal axis of the channel, so that the free space widens in a direction away from the external component when the hollow chamber profile is in the assembled state and forms an undercut. This undercut can be used to first insert the profile element at an angle into the free space and then bring it into its (straight) assembly position, which can be accompanied by a deformation of a part of the profile element, which ensures a frictional connection (see below).

In a particularly advantageous development of the hollow chamber profile according to the invention, it is provided that the profile element terminates flush with the projections when it rests against the outer outer wall within the free space in its assembled state. The profile element thus just fills the open hollow chamber profile without requiring additional installation space.

In another advantageous development of the hollow chamber profile according to the invention, it is provided that the profile element is designed as a hollow chamber profile element, preferably with at least two hollow chambers, with most preferably and with a corresponding configuration, the profile element Has recess for receiving the channel projection in its assembled state. The profile element is correspondingly lightweight with a relatively high mechanical load capacity. It can encompass the channel projection without this having an adverse effect on the installation space requirement.

1. a) wenigstens einen ersten Steg, der in dem Montagezustand bündig mit den Vorsprüngen abschließt; und/oder
2. b) wenigstens einen zweiten Steg, der in dem Montagezustand die Außenwandung berührt und dabei im Bereich des genannten Hinterschnitts angeordnet ist; und/oder
3. c) wenigstens einen dritten Steg, der in dem Montagezustand an einer seitlichen Begrenzung des Freiraums anliegt und zum Erzeugen eines Kraftschlusses verformt oder verformbar ist vorzugsweise zum Verrasten an dem erwähnten weiteren Vorsprung des Hohlkammerprofils.

In yet another advantageous development of the hollow chamber profile according to the invention, it is provided that the profile element has a number of outwardly protruding webs, namely:

1. a) at least one first web which terminates flush with the projections in the assembled state; and or
2. b) at least one second web which touches the outer wall in the assembled state and is arranged in the area of said undercut; and or
3. c) at least one third web, which rests against a lateral boundary of the free space in the mounted state and is deformed or deformable to produce a non-positive connection, preferably for latching on the mentioned further projection of the hollow chamber profile.

The web according to a) ensures the flush finish with the hollow chamber profile. The web according to b) ensures the support on the hollow chamber profile and can specifically enable the mentioned oblique insertion (pivoting). The web according to c) can preferably be angled laterally in relation to the rest of the profile element and have at least one predetermined buckling point or the like. In this area, the profile element is preferably wider than the clear width of the free space, so that it is deformed when it is inserted and thereby ensures a non-positive connection for fixing the profile element to the hollow chamber profile.

Two webs according to a) are preferably provided, which have projections facing one another, in particular at their free ends, so that an undercut is formed in which an optional stiffening element, e.g. made of flat steel, is held captive. This provides additional stability.

The profile element can also have a (lateral) projection, preferably opposite the third web, ie on a side facing away from the third web, which projection with the other such mentioned (Locking) projection in the area of the free space interacts in a locking manner in order to improve the holding effect.

Finally, another development of the hollow chamber profile according to the invention also provides that the lateral outer walls of the projections represent a smooth, level continuation of the lateral outer walls of the remaining hollow chamber profile. In other words: the protrusions represent an increase in the profile cross-section, which is not structurally visible from the profile when viewed from the side.

figure 1 shows a cross section through a conventional window profile or hollow chamber profile 1 according to the prior art with two steel reinforcements 2, 2 'and with a mounting means 3 (fastening screw) for fastening the window profile 1 to a structure or structure 4. The results are as described in detail in the introduction Disadvantages, in particular, the upper armouring chamber in the picture is only accessible from the outside (from the side of structure 4) via the other (lower) armouring chamber.

figure 2 shows a cross section through another conventional, open window profile or hollow chamber profile 1 according to the prior art with steel reinforcement 2 and with a mounting means 3 (fastening screw) for fastening the window profile 1 to a structure or structure 4. The disadvantages described in detail at the beginning arise , especially due to the large free screw length X.

The window builder must position himself between the two profiles 1 according to figure 1 and figure 2 decide or provide for double storage.

figure 3 shows a cross section through a hollow chamber profile 1 according to the invention. The hollow chamber profile 1 has a reinforcement integrated ex works, in particular made of a fiber composite material, at reference number 5 . Furthermore, the hollow chamber profile 1 has a fastening area at reference number 6, which is used to fasten the hollow chamber profile 1 to an external component or to connect the hollow chamber profile 1 to an external component, in the present case to a building (cf. figures 1 , 2 or 4 ), which is arranged below or outside of the hollow chamber profile 1 in the assembly direction (screwing direction). The fastening area 6 is designed to accommodate a fastening means profiled on the edge, namely the fastening screw (cf. figures 1 , 2 or 4 ), designed and provided, as can be seen, for example, from the figure 4 easy to see. The hollow chamber profile 1 has in the fastening area 6 a fastening channel 7 which is oriented perpendicular to a longitudinal extrusion direction 8 of the hollow chamber profile 1, which longitudinal extrusion direction 8 extends into the plane of the drawing. The fastening channel 7 has a channel longitudinal axis 9 which figure 3 is drawn as a dashed line. Furthermore, the mounting channel 7 closed at its ends perpendicular to the channel longitudinal axis 9 by an outer wall of the hollow chamber profile 1. These outer walls are in figure 3 provided with the reference numeral 1a (for the inner outer wall in the so-called fold area) or 1b (for the outer outer wall, which is to face the structure). Parallel to the longitudinal axis 9 of the channel, the fastening channel 7 is delimited laterally by channel side walls 7a, 7b. However, these channel side walls 7a, 7b are not designed to be smooth and continuous, but have various special features:

The fastening channel 7 is divided between the two outer walls 1a, 1b in the present case into two partial fastening channels 7.1 and 7.2, which partial fastening channels 7.1, 7.2 (also referred to here as screw chambers) are separated from one another in the direction of the longitudinal channel axis 9 by at least one intermediate area 10 are spaced. The intermediate area 10 is dimensioned sufficiently large that an additional reinforcement can be introduced into it (similar to reference number 2 in figure 2 ).

This results in the following picture with a view of the mentioned channel side walls 7a, 7b: the channel side wall 7a initially forms the left boundary of the (upper) partial fastening channel 7.1, then extends parallel to the outer wall 1a further to the left, away from the channel longitudinal axis 9, then bends parallel to the channel longitudinal axis 9 down and then merges into the outer wall 1b. The channel side wall 7b, on the other hand, initially forms the right boundary of the (upper) partial fastening channel 7.1, then extends obliquely upwards in the direction of the outer wall 1a and is then formed by the (right) reinforcement 5 or by the outer wall 1b.

In the intermediate area 10 are the fastening screws 3 (cf. figure 4 ) and the channel side walls 7a, 7b do not interact.

Alternatively, it could also be stated that the fastening channel 7 only has defined channel side walls in the area of the named partial fastening channels 7.1, 7.2. Accordingly, in the mentioned intermediate area 10 or possibly in further intermediate areas (see below) there is no channel side wall at all in the narrower sense, although of course inside of the hollow chamber profile 1 continuous structures exist parallel to the longitudinal axis 9 of the channel. Ultimately, in the embodiment shown, it is important that there are at least two aligned partial fastening channels 7.1, 7.2 along the longitudinal channel axis 9, which are not formed contiguously. In between there is said intermediate region 10 in which the fastening means 3 passes or can pass through the hollow chamber profile 1 without interacting with any structures within the hollow chamber profile 1 . This is well expressed by the alternatively or synonymously used term "screw chamber", because this suggests that the partial fastening channels are (closed) closed structures within the hollow chamber profile 1 . This also emerges in particular from the figures and applies to all of the configurations described and shown.

The upper screw chamber or the partial fastening channel 7.1 is formed between the outer wall 1a and a transverse web 11 arranged parallel to the outer wall 1a. The lower screw chamber or partial fastening channel 7.2 is designed to a certain extent as a projection or channel projection below the hollow chamber profile 1 (below the (profile) outer wall 1b). The outer wall 1a has a thickening or accumulation of material 12 within the hollow chamber profile 1, while projections 13 are provided on the side walls of the channel within the part-fastening channel 7.2, which extend approximately transversely to the longitudinal axis 9 of the channel. A clearance between the channel side walls 7a, 7b and the projections 13 in the area of the screw chambers is matched to the mounting or fastening means in such a way that this with its edge-side profile 3a ( figure 4 ) engages in the channel side walls or the projections 13.

In principle, the fastening means 3 can also be screwed into the screw chambers 7.1, 7.2 in the extrusion longitudinal direction 8 of the hollow chamber profile 1, for example in order to fasten additional elements, such as fittings or the like, to the hollow chamber profile 1.

The hollow chamber profile 1 according to figure 3 has in the area of the assembled state of the hollow chamber profile 1 the external component (cf. figures 1 and 2 ) facing or to be facing outer outer wall 1b two projections 14, 15, which in turn are designed as hollow profiles and each have a profile chamber 14a, 15a. At the end, the projections 14, 15 each have two webs 14b, 14c; 15b, 15c, which in turn have terminally angled structures 14d, 14e; 15d, 15e. The projections 14, 15 extend at a distance from and parallel to the channel longitudinal axis 9 and define between them an outwardly opening, clear free space 16 which extends parallel to the channel longitudinal axis 9 beyond the partial fastening channel (screw chamber) 7.2 . The screw chamber 7.2 projects into the free space 16 as a projection.

With reference numeral 17, the projections 14, 15 on their inner side facing the free space 16 each have a projection that is triangular in cross section. This projection 17 is formed so that its flat top is parallel to the outer wall 1b. As the further figures show, one of these projections 17 can also be dispensed with. The projection/projections 17 is/are primarily used to prevent loss of an optional (pre-assembled) insulating material in the back of the frame, e.g. for a styrofoam element (shown schematically at reference number 19).

At reference number 18 the free space 16 forms an undercut in that one of the projections 15 has on its inner side facing the free space 16 a section 15f oriented obliquely with respect to the longitudinal axis of the channel. Accordingly, the free space 16 widens in the assembled state of the hollow chamber profile 1 in a direction from the external component (cf. figure 4 ) away.

figure 4 shows essentially the same hollow chamber profile 1 as in FIG figure 3 , but with an additional profile element (sill) 100 inserted in the free space 16 and fastening screw 3 (with edge profile 3a) for fixing the hollow chamber profile 1 to a structure 4. For reasons of clarity, in figure 4 essentially only designates the features of the profile element 100 in more detail; it may otherwise on the figure 3 to get expelled.

Deviating from figure 3 has the hollow chamber profile 1 in figure 4 only one projection 17 on. For this, above this projection 17 is on the inside of the projection 14, a further projection 14f serving as a latching projection is formed, the function of which will be discussed in more detail below. Opposite the latching projection 14f there is another such latching projection 7.2a, which is arranged on the outside of the partial fastening channel (screw chamber) 7.2.

The profile element 100 has two hollow chambers 100a, 100b. On its side facing the structure 4, it has two webs 100c, 100d, with which it rests on the structure or on its insulating and insulating layer 4a attached between the structure 4 and the hollow chamber profile 1. The webs 100c, 100d close flush (in a common plane) with the webs 14b, 14c; 15b, 15c off. At the same time, the profile element 100 rests against the hollow chamber profile 1 in the area of the outer wall 1b with two webs 100e, 100f, which are arranged on the other side of the profile element 100. The web 100f is arranged in the area of the undercut 18 . Another web 100g protrudes laterally from the profile element 100 at an angle of approximately 90 degrees with respect to the (longitudinal) axis 9 of the channel. This web 100g has a predetermined kink point 100ga, so that its free end 100gb can be deformed inwards (in the direction of the free space 16) when it comes into contact with the projection 14, in order to hold or latch the profile element 100 in a non-positive manner in the free space 16. by placing the free end 100gb in the area of an undercut of the latching projection 14f. A lateral projection 100h, which is designed to interact with the snap-in projection 7.2a already mentioned, serves the same purpose.

When inserting the profile element 100, the profile element 100 is preferably first introduced obliquely into the undercut 18 with the web 100f. Then the entire profile element 100 is tilted counterclockwise, whereby the web 100g is deformed as described until the free end 100gb in the area of an undercut of the locking projection 14f and the lateral projection 100h lock with the already mentioned locking projection 7.2a. The projection/projections 17 is/are primarily used to prevent loss of an optional (pre-assembled) insulating material in the back of the frame, e.g. for a styrofoam element (at reference number 19 in figure 3 shown schematically). However, the projections 17 can also serve as an additional means of securing the profile element 100 against loss.

A clearance between the webs 14b, 14c or 15b, 15c is according to figure 4 filled with the material of the insulating and insulating layer 4a, so that there is a tight and secure connection between the structure 4 and the hollow chamber profile 1.

The fastening screw 3 passes through both screw chambers 7.1, 7.2 along the longitudinal axis 9 of the channel and also penetrates the profile element 100 in the region of the hollow chamber 100b. Above this hollow chamber 100b, the profile element 100 has a recess 100i, which serves to accommodate the channel projection or the screw chamber 7.2. The profile element 100 can thus fill the free space 16 without protruding.

How to get that in particular Figures 3 and 4 can still be seen, the screw chambers 7.1 and 7.2 have lateral thickenings or accumulations of material on their (screw channel) side walls, which are not indicated in the figures mentioned for reasons of clarity.

figure 5 shows the same hollow chamber profile 1 as in figure 4 , again with an additional profile element (sill) 100 used in the free space 16 and fastening screw 3 (with edge profile 3a) for fixing the hollow chamber profile 1 to a structure 4. For reasons of clarity, in figure 5 in turn, essentially only the features of the profile element 100 are described in more detail; it may otherwise revert to the figure 3 to get expelled.

Also shows figure 5 a stiffening element 200, which is preferably designed as a flat steel element and is inserted into the area between the webs 100c, 100d and an outer wall 100j of the profile element 100. For this purpose, said webs 100c, 100d have mutually facing projections 100ca, 100da at their free ends, so that an undercut is formed in said region. The stiffening element 200 is thus held captively between the webs 100c, 100d and preferably also on the outer wall 100j. The fastening screw 3 preferably also passes through the stiffening element 200.

figure 6 shows another hollow chamber profile 1 according to the invention, which essentially consists of the profile figure 3 is equivalent to. Only the main differences are briefly discussed here:

There are according to figure 6 no factory integrated stiffeners (reference number 5 in figure 3 ). In addition, the reinforcement chamber (intermediate area 10) is not double-walled on the left and at the top. The fastening channel 7 has only one screw chamber (at reference number 7.2), which screw chamber has a (locking) projection 7.2a. The projection 14 has on its inside two further projections 14f, 17 - as already mentioned; the projection 15 has no inside projection. The fold area (at reference numeral 1a) is essentially flat.

The fastening channel 7 is de facto reduced to the partial fastening channel or the single screw chamber 7.2.

figure 7 shows the hollow chamber profile 1 figure 6 together with the other profile element 100 according to figure 4 and a fixing screw 3. For details, refer to the corresponding description specifically to the Figures 3 and 4 referenced above.

Finally shows the figure 8 a section in or parallel to a glazing plane through a frame 20 for a door or a window, in particular a window frame, which consists of several sections 1.1-1.4 of hollow chamber profiles 1 according to the invention (cf. Figures 3 and 4 ) is formed. The hollow chamber profile sections 1.1-1.4 are connected to one another in pairs in connection areas 21, preferably welded. In the frame 20 shown, in each of the connecting areas 21 there is a preferably metallic connecting element 22 in the form of an L-shaped connecting angle with its two legs 23 (designated only for one connecting element 22) in two interconnected hollow chamber profile sections 1.1-1.4 in the area of the respective Intermediate area 10 (dash-dotted) introduced. It can be held therein with a clamping force fit or in some other way (eg materially bonded) in order to reinforce the connection areas 21 . This configuration is not restricted with regard to the type and number of connecting elements 22 .

The frame 20 can be connected to external components via the hollow chamber profile sections 1.1-1.4 in the manner described, for example to a reveal surrounding or receiving the frame (structure 4, not shown here, cf. figure 4 , 5 or 7 ).

By way of example, a reinforcement or a reinforcement element is introduced into one of the intermediate regions 10 at reference number 2 . Of course, the other intermediate areas 10 according to figure 5 record corresponding reinforcements 2. The reinforcements 2 can also extend into the connection areas 21, which in figure 5 is not shown.

In one of the free spaces 16, a profile element 100 is arranged as an example. Of course, the other free spaces 16 according to figure 5 record corresponding profile elements 100. The profile elements 100 can also extend into the connection areas 21, which is figure 5 is also not shown. The mentioned optional stiffening elements are not shown here.
