Description

[0001] The present invention relates to a composite profile for doors, windows or facade elements according to the preamble of claim 1 and to a method for assembling a composite profile.

[0002] Composite profiles of this type, such as those known from EP 0829609 A2, essentially consist of two outer metal profiles and an insulating profile connecting them. The metal profiles, together with the insulating profile, form a frame profile.

[0003] To assemble the metal profiles with the insulation profile, the metal profiles are pushed together longitudinally. Depending on the design of the connection between the insulation profile and the metal profile, this connection can be shear-resistant or shear-free. Shear-free means that the metal profile can be moved longitudinally relative to the insulation profile.

[0004] The problem with this type of assembly is that relatively large tolerances between the connecting webs and grooves of the profiles are necessary for longitudinal movement.

[0005] The object of the present invention is to provide a composite profile that is easy to manufacture and can be assembled in a simple and reliable manner.

[0006] The stated object is achieved by a composite profile for doors, windows or facade elements having the features of claim 1 and by a method having the features of claim 14.

[0007] The composite profile according to the invention comprises a first metal profile and a second metal profile as well as at least one insulating profile arranged between the metal profiles and connecting the metal profiles to one another.

[0008] The first metal profile has, on a side facing the second metal profile, a connecting region for connecting to a first connecting region of the at least one insulating profile. The second metal profile has, correspondingly, on a side facing the first metal profile, a connecting region for connecting to a second connecting region of the at least one insulating profile.

[0009] The connecting areas are designed as plug-in and / or snap-in connections, with plug-in and / or snap-in elements or plug-in and / or snap-in receptacles extending from or into the mutually facing sides.

[0010] At least one of the plug-in and / or snap-in connections has at least one pressing element for additional pressing of the plug-in and / or snap-in connection.

[0011] With a composite profile designed in this way, it is now possible not to push the metal profiles and the at least one insulating profile into each other in the longitudinal direction of the metal profiles and the insulating profile, but to place the at least one insulating profile in a sandwich-like manner between the metal profiles and then to connect the profiles to each other perpendicular to their longitudinal extent by pressing them together.

[0012] The additional pressure element on at least one of the plug-in and / or snap-in connections further ensures that the profiles are held together.

[0013] Advantageous embodiments of the invention are the subject of the subclaims.

[0014] According to an advantageous embodiment of the invention, at least one of the plug-in and / or locking elements is designed as a locking web that can be pressed into a respective plug-in and / or locking receptacle.

[0015] The at least one pressing element is preferably designed as a rolling strip.

[0016] This makes it possible that after one of the metal profiles has been plugged together with the at least one insulating profile by pressing on the roller strip, the profiles are held securely relative to one another by a further positive fit.

[0017] In a further preferred embodiment, at least one contact surface of the plug-in and / or locking receptacles is designed as a locking surface.

[0018] As a result, a pre-locking is already provided after a plug-in and / or locking element has been inserted into a plug-in and / or locking receptacle, which effectively prevents the adjacent components from slipping into an incorrect position before they are subsequently pressed together by the pressing element.

[0019] According to a further advantageous embodiment, a wire is accommodated in at least one of the connecting regions of the metal profiles and / or the at least one insulating profile.

[0020] This wire is used to create a shear-resistant, shear-free or shear-soft connection after the clamping element has been rolled up, depending on the processing of the wire used.

[0021] Thus, in a preferred embodiment, the wire can be formed with a flattening that creates a sliding surface to enable a shear-soft or shear-free connection.

[0022] According to a further preferred embodiment, it is also conceivable to form the wire or the flattening of the wire with a toothing or knurling and thus ensure greater shear strength.

[0023] According to a further advantageous embodiment, the plug-in and / or locking element of the insulating profile has an elastic tongue which can be pressed in against the spring force of the elastic tongue when the insulating profile is inserted into a plug-in and / or locking receptacle of one of the metal profiles.

[0024] This design also enables a simple pre-fixing, in particular locking of the insulating profile to the metal profile, so that subsequent pressing, in particular rolling of the pressing element, can take place for the final fixing of the two components to one another.

[0025] The at least one insulating profile is preferably formed in one piece.

[0026] In principle, however, it is also conceivable for the insulation profile to be constructed in several parts.

[0027] According to a further advantageous embodiment of the invention, the first metal profile has at least one groove-shaped screw channel extending in its longitudinal direction.

[0028] In a preferred development, a first screw channel is open to a first side of the first metal profile extending perpendicularly to the side facing the second metal profile, and a second screw channel is open to a second side of the first metal profile extending perpendicularly to the side facing the second metal profile and opposite the first side.

[0029] With a metal profile designed in this way, direct screwing of metal profiles is possible in a simple manner without machining.

[0030] According to a preferred embodiment, at least one thin-walled fixing web is formed in the first screw channel, into which a screw neck of a screw can be screwed in a cutting manner.

[0031] The thin-walled fixing web serves, on the one hand, to ensure the tightness of the first metal profile and, on the other hand, to improve the fixing of the respective component, such as a corner connector, with which first metal profiles that abut one another at an angle, in particular at right angles, can be fixed to one another.

[0032] The method according to the invention for assembling a composite profile involves the following process steps: Arranging at least one insulating profile between a first metal profile and a second metal profile, pressing the first and second metal profiles and the at least one insulating profile together in a direction perpendicular to the side of the first metal profile facing the second metal profile, wherein the plug-in and / or locking elements are pre-locked to the plug-in and / or locking receptacles, and rolling the at least one pressing element to fix the plug-in and / or locking connections of at least one of the first or second metal profiles to the at least one insulating profile.

[0033] Preferred embodiments are explained in more detail below with reference to the accompanying drawings.

[0034] They show: Figure 1a schematic sectional view of a composite profile with a surface element inserted therein in the assembled position, Figure 2a sectional view of an individual representation of the composite profile in the fully assembled state, Figure 3one of the Figure 2 corresponding representation of the composite profile before pressing the pressure element, Figure 4 a sectional view of another composite profile with metal profiles connected to each other via two insulating profiles in the fully assembled state, Figure 5 one of the Figure 4corresponding sectional view before the pressing elements are pressed on, Figure 6 a further sectional view of a first metal profile with an insulating profile attached thereto according to an alternative embodiment of the connecting areas of the insulating profile and the metal profile, Figures 7 and 8 schematic sectional view of a first metal profile and an insulating profile attached thereto with different self-locking elements for pre-locking the two components and Figures 9a - 9c a further embodiment of a first metal profile and an insulating profile with a further embodiment of a pre-locking element before insertion (a) in the pre-locked position (e) and in the finally assembled position after pressing on (c).

[0035] In the following description of the figures, terms such as top, bottom, left, right, front, rear, etc., refer exclusively to the exemplary representation and position of the composite profile, metal profile, insulating profile, connection areas, and the like chosen in the respective figures. These terms are not to be understood as limiting; i.e., these references may change due to different working positions or the mirror-symmetrical design, etc.

[0036] In the Figure 1 The reference numerals 2 and 9 designate variants of composite profiles according to the invention for doors, windows or facade elements.

[0037] Composite profile 2 is in Figure 1 the composite profile of a window, door or facade element sash and composite profile 9 the composite profile of a frame of the window, door or facade element.

[0038] The composite profile 2 has a first metal profile 3 and a second metal profile 4. When mounted on a building, one of these metal profiles 3, 4 is oriented towards the outside of the room and one towards the inside of the building when used on an external opening in a building.

[0039] The composite profile 9 of the frame has a first metal profile 6, a second metal profile 7 and two insulating profiles 8 arranged between the metal profiles 6, 7 and connecting the metal profiles 6, 7 to one another.

[0040] The first metal profile 3, 6 and second metal profile 4, 7 are preferably manufactured as extruded aluminum profiles.

[0041] It is also conceivable to manufacture it from a different material such as steel and / or using a different manufacturing process.

[0042] As in Figure 1 and in the Figures 2 to 5As further shown, an insulating profile 5, 8 connecting the metal profiles 3, 4, 6, 7 to one another is arranged between the metal profiles 3, 4, 6, 7.

[0043] In a Cartesian coordinate system, as in Figure 1 As shown, the X-axis and the Z-axis lie in the plane of the Figure 1 shown section, in which the Z-axis points in the direction of the height of the composite profile and the X-axis points in the direction of an imaginary connecting line from the first metal profile through the insulating profile into the second metal profile.

[0044] A Y-axis of the Cartesian coordinate system (not shown) extends in the direction of the longitudinal extent of the metal profiles 3, 4, 6, 7 and the insulating profiles 5, 8.

[0045] As particularly in the Figures 2 to 5As shown, the first metal profile 3, 6 has, on a side 32, 62 facing the second metal profile 4, 7, a connecting region 33, 63 for connection to a first connecting region 51, 81 of the at least one insulating profile 5, 8.

[0046] Accordingly, the second metal profile 4, 7 has a connecting region 43, 73 on a side 42, 82 facing the first metal profile 3, 6, which serves to connect to a second connecting region 52, 82 of the at least one insulating profile 5, 8.

[0047] In the Figures 4 and 5 as well as in Figure 1 In the composite profile 9 shown below, the metal profiles 6, 7 are connected to each other by two insulating profiles 8 arranged parallel to each other, while the Figure 1 upper composite profile 2, which is also in the Figures 2 and 3 shown, has a single insulating profile 5 which connects the two metal profiles 3, 6 together.

[0048] The connecting areas 33, 43, 63, 73, 51, 52, 81, 82 of the metal profiles 3, 4, 6, 7 and the insulating profiles 5, 8 are designed as plug-in and / or snap-in connections, with plug-in and / or snap-in elements 34, 53 or plug-in and / or snap-in receptacles 36, 44, 54, 64 extending from or into the mutually facing sides 32, 42, 62, 72.

[0049] In addition, at least one of the plug-in and / or snap-in connections has at least one pressing element 35, 65 for additionally pressing the plug-in and / or snap-in connection between the first or second metal profile 3, 4 and the at least one insulating profile 5, 8.

[0050] In the composite profile 2 of the door, window or facade element leaf, a hook-like plug-in and / or locking element 34 extends from the side 32 of the first metal profile 32 facing the second metal profile 4 into a plug-in and / or locking receptacle 54 of the insulating profile 5 receiving said plug-in and / or locking element.

[0051] The insulating profile, which is preferably made of a plastic, enables a spring-elastic reception of the plug-in and / or locking element 34, so that the first metal profile 3 and the insulating profile 5 are locked into the plug-in and / or locking receptacle 54 via the plug-in and / or locking element 34 after the profiles have been plugged together and are thus held in a form-fitting manner.

[0052] From the side of the insulating profile 5 facing the second metal profile 4, two plug-in and / or locking elements 53 project, which are aligned parallel to one another and also have hook-like ends and which engage behind a respective undercut in a connecting region 43 of the second metal profile 4 formed with a plug-in and / or locking receptacle 44.

[0053] For additional form-fitting fixing of the insulating profile 5 to the first metal profile 3, as shown in the Figures 2 and 3is shown, a pressing element 35, in particular in the form of a rolling strip, is formed on the first metal profile 3, which is formed by rolling from a Figure 3 shown from the insulating profile 5 protruding position into a Figure 2 shown position adjacent to the insulating profile 5 and thus ensures an additional positive connection for fixing the insulating profile 5 to the first metal profile 3.

[0054] In principle, it is conceivable to form a corresponding connection between the second metal profile 4 and the insulating profile 5.

[0055] In the composite profile 9, as shown in the Figures 4 and 5As shown, such pressing elements 65, 75 are provided on both the first metal profile 6 and the second metal profile 7, with which, after inserting the connecting regions 83 of the insulating profile 8, which are here approximately trapezoidally shaped, into the plug-in and / or locking receptacles 64, 74 of the first metal profile 6 or the second metal profile 7 provided for this purpose, these are fixed in a form-fitting manner, preferably by rolling on the pressing elements 65, 75, which are preferably designed as a rolling strip.

[0056] In order to ensure a reliable pre-positioning of the connecting areas 51, 52, 81, 82 of the insulating profiles 5, 8 in the first metal profile 3, 6 or second metal profile 4, 7 before pressing the pressing elements 35, 65, 75, a contact surface 38 of the plug-in and / or locking receptacles 36, 44, 74 is preferably designed as a locking surface, as is shown for example in Figure 8 is shown.

[0057] The contact surface 38 designed as a locking surface can be designed with a ribbing or toothing, so that after inserting one end of the insulating profile 5, 8, a pre-fixing is provided, in particular in the direction of the X-axis.

[0058] Alternatively or additionally, it is also conceivable to form an elastic tongue 56 on the plug-in and / or locking element 53 of the insulating profile 5, which is pressed against the spring force of the elastic tongue 56 when the insulating profile 5 is pushed into the plug-in and / or locking receptacle 36 provided for this purpose in the first metal profile 3 or analogously in the second metal profile 4, as shown in the Figures 9a) to 9c ) is shown.

[0059] It is also conceivable, for example, within the plug-in and / or locking receptacle 36 of the first metal profile 3, as shown in Figure 8As shown, a locking web 37 is provided, which projects into a groove 57 provided for this purpose in the plug-in and / or locking element 53 of the insulating profile 5. The locking web 37 preferably has an elastic, thickened end, so that here too a locking connection between the first metal profile 3 and the insulating profile 5 is provided that is sufficient for pre-positioning.

[0060] It is also conceivable that a wire 12 is accommodated in at least one of the connecting regions 33, 43 of the metal profiles 3, 4 and / or the insulating profile 5.

[0061] This wire 12 can be designed as a round wire, which, after subsequent rolling of the pressure element 35, leads to a slip-resistant connection (in the longitudinal direction of the profiles).

[0062] The wire 12 can also be formed with a flattened portion to enable metal contact between the first metal profile 3 and the insulating profile 5 and thus create a shear-free or low-shear connection.

[0063] It is also conceivable to form the flattening in the wire 12 with a toothing or knurling in order to adjust the degree of freedom of movement more precisely.

[0064] How to continue in the Figures 1 to 3 As shown, the first metal profile 3 has at least one, in the embodiment shown two, groove-shaped screw channel or screw channels (39a, 39b) extending in its longitudinal direction.

[0065] A first screw channel 39a is open to a first side of the first metal profile 3 extending perpendicularly to the side 32 facing the second metal profile 4. This first screw channel serves in particular to fix a corner support 13, shown in Figure 1, which has two legs extending at an angle, in particular at right angles, to one another, which are connected to one another in a corner region and serves for the at least additional fixation of two first metal profiles 3 lying at right angles to one another.

[0066] One of the legs has a web 18, which, when assembled, is received in a groove 15 of the first metal profile 3. Furthermore, the corner support 13 rests with a bottom side facing away from the surface element 11 on a load-bearing surface 14 of the first metal profile 3 and, in cooperation with a counter web 16 defining the groove 15, thus enables the load of the surface element 11 acting on the corner support to be transferred into the first metal profile 3.

[0067] A second screw channel 43 is open to a second side of the first metal profile, extending perpendicularly to the side 32 facing the second metal profile 4 and opposite the first side. The second screw channel 43 serves, for example, for screwing together two first metal profiles 3 that are adjacent to one another at an angle, in particular at right angles, so that screwing of metal profiles is possible without machining.

[0068] Furthermore, for improved holding and sealing, at least one thin-walled fixing web 17 is formed in the first screw channel 39a, into which the screw neck of a screw can be screwed cuttingly.

[0069] In the method according to the invention for assembling a composite profile 2, in a first method step, at least one insulating profile 5, 8 is arranged between a first metal profile 3, 6 and a second metal profile 4, 7. The profiles are then pressed together in a direction perpendicular to the side 32, 62 of the first metal profile 3 facing the second metal profile 4, 7.

[0070] By pressing them together, the plug-in and / or locking elements 34, 53 are pre-locked with the plug-in and / or locking receptacles 36, 44, 54, 64.

[0071] Subsequently, the at least one pressing element 35, 65 is rolled to fix the plug-in and / or locking connections of at least one of the first or second metal profiles 3, 4, 6, 7 with the at least one insulating profile 5, 8. Reference symbol
