Composite profile for windows and / or doors

Description

[0001] The invention relates to a composite profile having the features of the preamble of claim 1. The composite profile can be used in particular for the production of windows and / or doors. Furthermore, the invention relates to a window or door element with at least one movable sash comprising a composite profile according to the invention.

[0002] If we are talking about a window or a window element, this term also includes those that are designed as French doors. State of the art

[0003] Composite profiles for the manufacture of windows and / or doors are known from the prior art. These profiles comprise at least two metal profiles and an insulating profile for thermally separating the two metal profiles. The metal profiles possess high dimensional rigidity, allowing them to withstand high loads. However, a comparatively high thermal conductivity proves to be a disadvantage, so that thermal separation is necessary to prevent the formation of a thermal bridge. The insulating profile used for thermal separation is usually made of plastic, as plastic has a significantly lower thermal conductivity than metal. To achieve a sufficiently stable bond between the insulating profile and the two metal profiles, the insulating profile is usually connected to the two metal profiles using a force-fitting and form-fitting method.

[0004] A composite profile and a method for producing the composite profile are disclosed, for example, in application EP 3 048 231 A1 by the same applicant.

[0005] Other composite profiles are known, for example, from EP 1 138 864 A1, from DE 100 15 838 A1 and from GB 2 470 217 A.

[0006] A composite profile of the type mentioned above is disclosed in DE 298 05 579 U1.

[0007] Based on the aforementioned prior art, the present invention seeks to further develop a composite profile of the aforementioned type in such a way that the inclusion of necessary hardware components is optimized. In particular, the inclusion of necessary hardware components should not be at the expense of thermal separation, thus creating a composite profile that meets the highest thermal insulation requirements. Furthermore, the composite profile should have the narrowest possible face widths.

[0008] To achieve this objective, the composite profile having the features of claim 1 is proposed. Advantageous further developments of the invention are set forth in the subclaims. Furthermore, a window or door element having such a composite profile is proposed. Disclosure of the invention

[0009] The proposed composite profile for windows and / or doors comprises at least one metal profile and an insulator, wherein the insulator is connected to the metal profile in a force-fitting and / or form-fitting manner via an end section that is received in a receiving groove of the metal profile. The insulator and the metal profile cooperate to form a fitting groove, wherein the insulator has a web section arranged at an angle to the end section for delimiting the fitting groove and at least one web section for a force-fitting and / or form-fitting connection to a glass retaining profile. According to the invention, the metal profile is produced by forming a metal sheet, wherein two metal sheet edges extending in the longitudinal direction of the metal profile delimit the receiving groove.

[0010] A fitting groove is typically used to accommodate a fitting component of a window and / or door. This fitting component ensures that the window or door can be opened and closed. For example, a movable sash of the window and / or door can be mounted for rotation and / or tilt movement via a fitting component. Furthermore, a fitting groove can be used to accommodate other accessories, such as a seal (e.g., a sliding seal or an automatic floor seal), an additional locking device, and / or an electronic component (e.g., for locking control).

[0011] To permanently and securely mount and / or secure a fitting component, the fitting groove that accommodates the fitting component is generally located in an area that possesses comparatively high strength, particularly dimensional rigidity. In a composite profile comprising at least one metal profile and an insulator, this is usually the area of ​​the metal profile. This means that the metal profile forms the fitting groove. The formation of the fitting groove, in turn, requires space, which generally compromises thermal separation and results in a reduction in thermal insulation.

[0012] In contrast, in the proposed composite profile, the insulator and the metal profile work together to form a fitting groove. This means that the fitting groove is not formed by the metal profile alone, but by the metal profile and the insulator. The space occupied by the fitting groove is thus not detrimental to the thermal separation, which in turn has a positive effect on thermal insulation.

[0013] To define the fitting groove, the insulator has a web section arranged at an angle to the end section. This angular arrangement is particularly clearly visible in the cross-section of the insulator. The angle formed by the web section and the end section of the insulator can be, for example, 90°. The web section arranged at an angle to the end section can, in particular, form a lateral boundary wall of the fitting groove.

[0014] Furthermore, the insulator is provided with at least one web section for a force-fitting and / or form-fitting connection to a glass retaining profile. This means that the insulator is not only involved in the formation of the fitting groove, but also in the reception and / or fixation of the glass retaining profile. Thus, the reception and / or fixation of the glass retaining profile does not compromise thermal separation, which in turn is advantageous in terms of thermal insulation. The glass retaining profile can be used to hold not only a pane of glass, but also a panel.

[0015] The metal profile of the composite profile is manufactured from a metal sheet by forming, in particular by roll forming. In this way, a metal profile with a complex profile cross-section can be manufactured comparatively easily and cost-effectively. The receiving groove of the metal profile, which serves to provide a force-fitting and / or form-fitting connection between the metal profile and the insulator, is defined by two metal sheet edges extending in the longitudinal direction of the metal profile. The metal sheet edges can be plastically deformed in a simple manner, for example by rolling, in order to establish the force-fitting and / or form-fitting connection between the metal profile and the insulator. Furthermore, the metal sheet edges defining the receiving groove can each have a flange or a fold at their ends.The flange or fold reinforces the edge area and can also be used to create a positive connection between the metal profile and the insulator. The flange or fold is then arranged such that it engages behind an undercut area of ​​the insulator.

[0016] In one embodiment, it is proposed that the web section delimiting the fitting groove extends in the longitudinal direction of the insulator. In this case, the "longitudinal direction" refers to a direction parallel to the longitudinal direction of the profile of the insulator. The groove thus extends in the longitudinal direction of the profile, so that the fitting component and / or accessory accommodated therein also extends in the longitudinal direction of the profile or parallel to an edge of a frame made from the composite profile for a window and / or door. In this way, for example, frames can be formed that have locking devices or circumferential seals extending along a closing edge.

[0017] The web section of the insulator preferably has a cross-sectional width that ensures sufficient strength, in particular dimensional rigidity, so that a fitting component or other accessory accommodated in the fitting groove is permanently and securely mounted and fixed.

[0018] Preferably, the web section of the insulator interacts with a web section of the metal profile to limit the fitting groove.

[0019] Furthermore, it is therefore proposed that the metal profile have a web section arranged at an angle to the receiving groove to define the fitting groove. This angular arrangement is particularly clearly visible in the cross-section of the metal profile. The angle formed by the web section and the receiving groove of the metal profile can be, for example, 90°. The web section arranged at an angle to the receiving groove can, in particular, form a lateral boundary wall of the fitting groove.

[0020] To form a lateral boundary for the fitting groove, the web section of the metal profile preferably extends in the longitudinal direction of the metal profile, i.e., parallel to the web section of the insulator. This creates a fitting groove that has a consistent width in the longitudinal direction.

[0021] The metal profile preferably has a profile section in its cross-section that defines the receiving groove on the one hand and the fitting groove on the other. This can, in particular, be a profile section that forms a lateral boundary wall of the receiving groove and, at the same time, a groove base of the fitting groove. In this way, the space available for forming the grooves is optimally utilized.

[0022] The profile section of the metal profile forming the groove base of the fitting groove can also have, on the fitting groove side, at least one rib-like geometry extending in the longitudinal direction of the metal profile, which is raised relative to the groove base and thus enables adjustment of the height of a fitting component received in the fitting groove. Furthermore, only linear contact of the fitting component with the rib-like geometry proves advantageous. Preferably, the profile section forming the groove base of the fitting groove has at least two rib-like elevations to form an intermediate groove, which can be used to guide and / or position fasteners for attaching the fitting component or accessories.

[0023] In a further development of the invention, it is proposed that the insulator forms at least one further groove which runs parallel to, in particular adjacent to, the fitting groove. Preferably, both grooves are arranged on the same side of the insulator. The further groove can be used to accommodate commercially available accessories (e.g. seals, additional locking devices and / or electronic components) or at least one further fitting component. The further groove can therefore also be a further fitting groove. This can be designed identically to or similarly to the first fitting groove. Preferably, the further groove is separated from the fitting groove by the aforementioned web section of the insulator. In this case, the web section is used to delimit both grooves, i.e. the fitting groove and the further groove, so that the formation of the grooves takes up less space.

[0024] Advantageously, the fitting groove and / or the additional groove have a standardized, preferably standardized, dimension. This allows fitting components and / or accessories from different manufacturers to be inserted into the respective groove. For example, the fitting groove and / or the additional groove can form a 16x8 Euro groove and / or an 8x4 Euro groove.

[0025] The web section intended for the force-locking and / or form-locking connection to the glass retaining profile is preferably designed with an angled cross-section. The angled cross-section of the web section makes it possible, in particular, to achieve a form-locking connection with the glass retaining profile. For example, the web section can have an L-shaped cross-section. Alternatively or additionally, it is proposed that the web section for the force-locking and / or form-locking connection to the glass retaining profile be arranged on the side of the insulator facing away from the fitting groove. The insulator thus forms a glass side and a fitting side.

[0026] In the region of at least one end section, the insulator preferably has an undercut region which enables a positive connection with the metal profile.

[0027] The insulator preferably has a substantially or at least approximately mirror-symmetrical profile cross-section. The mirror-symmetrical profile cross-section simplifies the manufacture and assembly of the insulator. The axis of symmetry preferably runs centrally between two end sections of the insulator, so that the insulator can have a glass side and a fitting side that are differently designed.

[0028] Furthermore, the insulator is preferably made of plastic. Plastic has significantly reduced thermal conductivity compared to metal, so that effective thermal separation can be achieved via the insulator. The insulator is preferably made of a plastic with high strength, for example polyamide, in particular PA6.6. Alternatively or additionally, it is proposed that the plastic be fiber-reinforced. The plastic can in particular contain glass fibers for reinforcement. According to a preferred embodiment of the invention, the insulator is made of PA6.6 GF25. The high strength and / or reinforcement of the plastic ensures(s) a permanently secure reception and fixation of fitting components and / or accessories in the grooves provided for this purpose.

[0029] The metal profile preferably forms a profile loop in cross-section, which is formed by profile sections that directly border the receiving groove and / or overlap at least in part. Complex profile cross-sections can be realized via the profile loop. For example, web- and / or flange-forming profile cross-sections can be created that possess high dimensional rigidity. At the same time, the web and / or flange can be used as a stop or the like. If the profile sections of the profile loop overlap at least in part, so that the metal sheet is doubled in this area, the dimensional rigidity can be further increased.

[0030] The metal profile of the proposed composite profile is preferably thermally separated from another metal profile by the insulator. This means that the composite profile comprises at least two metal profiles and the insulator for thermally separating the two metal profiles. The metal profiles determine the visible widths of the composite profile. Furthermore, the insulator is preferably connected to the other metal profile in a force-fitting and / or form-fitting manner via an end section received in a receiving groove of the other metal profile. The connection can, in particular, be designed identically to the connection of the insulator to the first metal profile. In this case, the insulator has identical end sections for connecting to the metal profiles. This simplifies the manufacture and / or assembly of the insulator.

[0031] Since the composite profile according to the invention is particularly suitable for the production of windows and / or doors, a window or door element with at least one movable sash is also proposed, which comprises a composite profile according to the invention. A fitting component can be inserted into the fitting groove of the composite profile, which serves to mount the sash in a movable, in particular rotatable and / or tiltable manner. The sash is preferably mounted on a frame profile, which can also comprise a composite profile according to the invention or be formed by such a profile. Alternatively or additionally, the fitting groove of the composite profile of the sash can be used to accommodate accessories, such as additional locking devices, seals and / or electronic components.

[0032] The claimed window or door element can be either a single-leaf or a multi-leaf system. In the latter case, the composite profile of the movable sash preferably interacts with a composite profile of another movable sash to form a stop. This means that a mullion stop is formed. The mullion stop eliminates the need for a fixed post as a stop, thus minimizing the overall visible width of the profiles.

[0033] In a further development of the invention, it is proposed that the composite profiles, which interact to form a stop, have facing fitting grooves that are offset from one another in the profile cross-section. This means that when the window or door is closed, the fitting grooves of the composite profiles, which interact to form a stop, are not opposite one another, but rather lie next to one another or one behind the other. In this way, the stop depth can be maximized, which in turn minimizes the overall visible width of the profiles.

[0034] Preferred embodiments of the invention are described in more detail below with reference to the accompanying drawings. These show: Fig. 1 shows a schematic cross-section through a first preferred embodiment of a composite profile according to the invention for a sash in conjunction with a composite profile for a frame, Fig. 2 shows a schematic cross-section through a second preferred embodiment of a composite profile according to the invention for a sash, Fig. 3 shows a schematic cross-section through a third preferred embodiment of a composite profile according to the invention for a sash, Fig. 4 shows a schematic cross-section through a fourth preferred embodiment of a composite profile according to the invention for a sash, Fig. 5 shows a schematic cross-section through a fifth preferred embodiment of a composite profile according to the invention for a sash in conjunction with a composite profile of another sash, Fig. 6 shows a cross-section through a sixth preferred embodiment of a composite profile according to the invention for a sash,7a cross-section through a single-leaf window element, comprising the composite profile of the .

[0035] Drawings 1-5 show a schematic representation of a composite profile according to the invention, wherein the web section for the force-locking and / or form-locking connection with a glass retaining profile is not explicitly shown. Detailed description of the drawings

[0036] The Fig. 1 1 shows a composite profile 1 for forming a sash 14 of a window element, which comprises a first metal profile 2, a second metal profile 2' and an intermediate insulator 3 for thermally separating the two metal profiles 2, 2'. The insulator 3 and the first metal profile 2 interact to form a fitting groove 6. A fitting component (not shown) or another accessory, such as a seal, an additional lock or an electronic component, can be inserted into the fitting groove 6. The fitting groove 6 is delimited on the one hand by a web section 7 of the insulator 3 and on the other hand by a web section 8 of the metal profile 2, so that the two web sections 7, 8 each form lateral boundary walls of the fitting groove 6.

[0037] Because the insulator 3 and the metal profile 2 interact to form the fitting groove 6, the insulator 3 can be dimensioned larger, thus increasing the distance between the two metal profiles 2, 2'. This creates an effective thermal separation that improves thermal protection.

[0038] The Fig. 1 A composite profile 15 can also be seen, which in this case serves to form a frame for the window element. The composite profile 15 is designed analogously to the composite profile 1 of the sash 14, but without the fitting groove 6. This means that the composite profile 15 can be a conventional composite profile.

[0039] In the Fig. 2 is a modification of the composite profile 1 of the Fig. 1 shown. The modification consists in that in addition to the fitting groove 6, a further groove 10 is provided, which is formed by the insulator 3. The insulator 3 has for this purpose a further web section 7', which runs parallel to the web section 7. The web section 7 can thus be used on the one hand to limit the fitting groove 6, and on the other hand to limit the further groove 10. Alternatively or in addition to the fitting groove 6, a fitting component or an accessory part can be inserted into the further groove 10, so that greater variation options exist in order to take into account the respective structural conditions. In the example of the Fig. 2 the further groove 10 is designed in the same way as the fitting groove 6, namely as a Euro groove 16x8.

[0040] Fig. 3 shows a further modification of a composite profile 1 according to the invention. Here, the fitting groove 6 and the additional groove 10 are each designed as a Euro groove 8x4. For example, a fitting component 16, 16' is inserted into both grooves 6, 10.

[0041] The Fig. 4 Another preferred embodiment of a composite profile 1 according to the invention can be seen. Here, the fitting groove 6 is designed as a 16x8 Euro groove. The other groove 10, in contrast, is designed as an 8x4 Euro groove.

[0042] The Fig. 5 shows a composite profile 1 in conjunction with another composite profile 1', which serves to form another sash 14'. The composite profiles 1, 1' of both sashes 14, 14' interact to form a stop. This means that the sashes 14, 14' interlock. The stop is therefore a casement stop. The window comprising the sashes is therefore a casement window. In order to achieve the smallest possible overall visible width, the fitting groove 6' of the composite profile 1' is offset from the fitting groove 6 of the composite profile 1. The fitting groove 6' is formed solely by the insulator 3', so that it lies entirely within the area of ​​the thermal separation. The formation of the fitting groove 6' therefore does not compromise the thermal separation. In this way, an optimal thermal separation is achieved between the two metal profiles 2" and 2" of the composite profile 1'. Fig. 5 For example, a fitting component 16, 16' is inserted into each of the two fitting grooves 6, 6'.

[0043] A further preferred embodiment of a composite profile 1 according to the invention is shown in Fig. 6 shown. It has two metal profiles 2, 2' and an insulator 3 for thermally separating the two metal profiles 2, 2'. Both metal profiles 2, 2' are produced from a metal sheet by forming, in particular by roll forming. The metal sheet edges each delimit a receiving groove 4, 4' for receiving an end section 5, 5' of the insulator 3. The ends of the metal sheet edges are each provided with a fold 18, 18', which engage behind an undercut area of ​​the end sections 5, 5'. In this way, a positive connection of the insulator 3 with the metal profiles 2, 2' is achieved. Profile sections adjoining the respective receiving groove 4, 4' form a profile loop 13, 13', which serves to form at least one web and at least one flange. In the metal profile 2, the profile loop 13 also forms a web section 8, which serves to laterally limit a fitting groove 6.On the other side, the fitting groove 6 is delimited by a web section 7 of the insulator 3. The web section 7 also delimits - together with a web section 7' ​​- another groove 10. Fitting components 16, 16' can be inserted into both the fitting groove 6 and the other groove 10 (see . Fig. 7 ).

[0044] The fitting groove 6 is delimited at the groove base by a profile section 9 of the metal profile 2, which simultaneously forms a lateral boundary of the receiving groove 4. In this way, the space available for forming the grooves 4, 6 is optimally utilized.

[0045] On the side facing away from the grooves 6, 10, the insulator 3 has web sections 11, 11', which can be used to hold and fix glass retaining profiles 12 (see Fig. 7 ). For this purpose, the web sections 11, 11' are angled or L-shaped in cross-section. Since the load on the web sections 11, 11' is significantly lower than that on the web sections 7, 7', they have significantly smaller cross-sections.

[0046] In the Fig. 7 The composite profile 1 is shown with the insulating glass pane 17 and glass retaining profiles 12 inserted therein. On the side of the composite profile 1 facing away from the insulating glass pane 17, a fitting groove 6 and a further groove 10 are formed. On the left side of the Fig. 7 For example, a fitting component 16 is inserted into the fitting groove 6. On the right side of the Fig. 7 For example, a fitting component 16, 16' is inserted into each of the two grooves 6, 10.

[0047] Furthermore, the Fig. 7 As can be seen, the frame of the window element shown in cross-section is also designed as a thermally separated composite profile, whereby the composite profile 15 does not have a fitting groove 6.

[0048] A composite profile 1 for a double-leaf window element with two movable leaves 14, 14', which overlap, is shown as an example in the Fig. 8 The composite profile 1 is almost identical to the composite profile 1 of the Fig. 6 The metal profile 2 merely forms a slightly differently shaped profile loop 13. The composite profile 1 interacts with a composite profile 1' to form a stop, whereby the stop is designed as a faceplate stop (see Fig. 9 ). The further composite profile 1' has an insulator 3' for the thermal separation of two metal profiles 2", 2‴. Furthermore, the insulator 3' forms a further groove, which in this case serves as a fitting groove 6' (see Fig. 9 ) and is therefore designated as such.

[0049] As in particular the Fig. 9 As can be seen, the fitting groove 6' is offset from the fitting groove 6 of the composite profile 1. When the sashes 14, 14' are closed, the fitting components 16, 16' inserted into the fitting grooves 6, 6' do not collide with each other. The offset arrangement optimally utilizes the available space, allowing the stop depth to be increased to achieve a narrow overall visible width. List of reference symbols
