Description

The invention relates to a composite frame, which can be connected to add-on parts, for a window or a door made of plastic profiles with attached metal profiles.

technical field

Plastic has established itself in many markets as a material for frame profiles for the manufacture of windows and doors because of the rational further processing and longevity of the products. Plastic profiles are always mitred and welded together in the miter area to form a frame. At least in the case of larger processors, the production of blind and sash frames from plastic profiles usually takes place on complex production lines in which the individual work steps take place in sequence. In order to enable efficient production, none of the individual work steps must take significantly longer than other work steps, since otherwise the entire production line would have to be operated correspondingly more slowly.

The use of facing shells or frames made of metal profiles and in particular aluminum profiles is well known for both wooden and plastic windows. The cladding of plastic profiles with aluminum shells or frames is primarily for aesthetic reasons, whereby the aluminum shells or frames can be anodized in different colors, painted or otherwise coated.

In this application, individual facing profiles are referred to as facing shells, which—without being connected to one another in the corner or miter area—are placed individually on the legs of a base frame and connected to it.

In this application, prefabricated frames made of attachment profiles are referred to as attachment frames, which are connected to one another to form a fixed attachment frame before being connected to or placed on a base frame in the corner or miter area. The corner connection can, for example, by means of special corner brackets, as from the DE 100 08 037 B4 , the DE 88 08 313 U1 or the EP 1 914 375 B1 are known, or, in the case of particularly high-quality designs, by welding in the miter area.

State of the art

Plastic frame for a window or a door with outer, prior to placement on the base frame not interconnected individual shells are, for example, from the EP 1 877 640 B1 or the DE 100 02 658 A1 famous.

In this case, a front frame or a front shell is connected to a plastic frame, the plastic frame consisting of four plastic profiles cut to a miter and welded together in the miter area to form a frame.

The glazing is inserted centrally in the casement frame. On one side of the glazing, it is held by a bend in the base frame or the attachment frame or the attachment shell; to avoid burglary, this is mostly the surrounding side. A glazing bead is installed on the other side to hold the glazing in place.

Locking systems are used to firmly lock the sash frame in a window frame and are also connected to composite frames.

task

Object of the present invention is therefore to provide a generic composite frame for a window or door available in which attachments such as Glazing beads and locking systems can be connected with a secure hold and elegantly integrated.

Presentation of the invention

The invention solves this problem with a composite profile for a window or a door, which comprises at least one plastic base profile and an inner facing metal profile, with “inside” referring to the installation position inside a house. Accordingly, an optional outer facing metal profile is arranged on the surrounding side. The inner metal profile and the plastic base profile each have means that together form a latching function, so that the inner metal profile and the plastic base profile can be connected to one another by the latching function. The inner facing metal profile is an extrusion profile. This has an outer surface which is aligned at least approximately vertically in the installed position. An at least approximately vertical alignment also includes a slight curvature or a small angle. A typical installation position is understood to mean that in which the main axis of the glazing is vertical. For the sake of the simpler wording of the patent, the description refers to this installation case. The protection also includes windows of the same construction, but installed at an angle as roof windows, for example. According to the invention, the inner facing metal profile has a hook which, in the installed position, forms a latching function together with a means of the plastic base profile. On the side facing away from the center of the plastic base profile, this hook has a hook surface aligned at least approximately perpendicularly to the vertically aligned outer surface. In the latched state, there is a gap between the inner attachment metal profile and the plastic base profile on the side of the hook facing away from the middle of the plastic base profile. This gap is used to attach add-on parts. The hook surface with its orientation is suitable for both hooking and screwing attachments.

The plastic base profile has an overhang which, in the latched state, runs at least approximately parallel to the hook surface and partially covers it in the horizontal direction.

This forms a glazing bead holding groove, which can also be used to hold locking parts, with the alignment of the hook perpendicular to the glazing plane

Advantageous configurations result from the features of the dependent claims.

In a preferred embodiment of the invention, a glazing bead hook of a glazing bead can be inserted through the gap between the plastic base profile and the inner attachment metal profile and latched between the hook surface and the aforementioned overhang.

Optionally, at least one fastener of a locking part can be inserted through the gap between the plastic base profile and the inner facing metal profile and connected to the hook. According to a preferred embodiment, the closing part has at least one sleeve which is positioned in the gap in the assembled state. In this case, the fastening means is preferably a screw and a bore or a thread is arranged in the hook. The screw can thus be screwed to the hook on the one hand. On the other hand, the screw can be passed through the hook and screwed to the plastic base profile underneath.

The inner facing metal profile preferably covers the plastic base profile in the viewing direction perpendicular to the outer surface. The base body is therefore not visible to an observer in the building when the window is closed.

The same reference symbols in different figures have the same meaning. Not all reference numbers are shown in all figures.

figure 1 shows a plastic base profile 2 in the form of a casement base profile 3 with two matching attachment metal profiles 5, 6. When installed, the left-hand side faces the surroundings of a house (weather side), while the left-hand side faces the interior of the building.

The casement base profile 3 has a rounded bulge 16 in the upper area on both outer sides, which connects the vertical, outer wall at an angle of around 50° on the inside or 310° on the outside with a slope that is directed inwards and downwards. The casement base profile 3 has in the lower area on both outer sides a bevel with an angle of around 45° on the inside and 315° on the outside, which is directed inwards and downwards and ends in an undercut 12 upwards. There is an adhesive strip 13 on each of the outer sides.

The two attachment metal profiles 5, 6 each have a hook 15 in the upper area and a locking lug 11 in the lower area on the side facing the casement basic profile 3 . The inner attachment metal profile 6 has a in the installation position (compare figures 5 and 7 ) vertically oriented outer surface 17. Furthermore, the hook 15 has, on the side facing away from the bulge 16 of the plastic base profile 2, a hook surface 18 oriented perpendicularly to the vertically oriented outer surface 17. In the installed position (cf figures 5 and 7 ) the hook surface 18 is thus arranged horizontally.

figure 2 differs from figure 1 essentially in that a window frame base profile 4 is arranged in the middle instead of a sash base profile as the plastic base profile 2 is. The two attachment metal profiles 5, 6 are individually adapted to the frame base profile 4 and each have a hook 15 at the top and a locking lug 11 at the bottom. The outer frame base profile 4 essentially corresponds to the casement base profile 3 on the outer sides and also has a corresponding rounded bulge 16 and a corresponding undercut 12.

figure 3 shows how the two attachment metal profiles 5, 6 are connected to the casement base profile 3 by the hooks 15 being slipped around the bulges 16. The two attachment metal profiles 5, 6 are thereby tilted with the top inward to the casement base profile 3.

Before hooking in, the adhesive strips 13 must either be attached or - if they were already attached - a protective film on the side facing outwards must be removed.

figure 4 shows analogously how the two attachment metal profiles 5, 6 are connected to the frame base profile 4.

The attachment metal profiles 5, 6 are then firmly connected to the sash frame basic profile 3 and window frame basic profile 4 by turning the respective outer attachment metal profile 5 counterclockwise, as a result of which the locking hook 11 slides along the slope 14 in front of the undercut 12 and then the locking hook 11 slides into the undercut 12 snaps into place. The same happens on the other side, on which the respective inner facing metal profile 6 is turned clockwise, whereby the latching hook 11 of the inner facing metal profile 6 slides along the slope 14 in front of the undercut 12 of the sash frame base profile 3 or frame base profile 4 and then the latching hook 11 in the Undercut 12 engages.

figure 5 shows the casement base profile 3 with the two firmly latched intent metal profiles 5, 6 and an unmounted Glazing bead 8. In this latched state, a gap 19 is formed between the inner attachment metal profile 6 and the plastic base profile 2 on the side of the hook 15 facing away from the bulge 16 of the plastic base profile 2; this gap 19 forms a glazing bead retaining groove. figure 13 shows this enlarged. The glazing bead 8 has a glazing bead hook 21 on the underside and a sealing groove 22 into which a seal (not shown) can be inserted for sealing and vibration damping of the glazing. The plastic base profile 2 has an overhang 20 which, in this latched state, runs parallel to the hook surface 18 and partially covers it in the horizontal direction.

figure 6 shows the window frame base profile 4 with the two firmly latched facing metal profiles 5, 6 and a non-mounted locking part 9 and a screw 10. Here too, in this latched state, between the inner facing metal profile 6 and the plastic base profile 2 on the side facing away from the bulge 16 of the plastic base profile 2 of the hook 15 a gap 19 is formed. This gap 19 can also be used as a glazing bead retaining groove for fixed glazing or to accommodate locking parts 9. figure 15 shows this enlarged. The closing part 9 has a sleeve 23 on the underside.

figure 7 shows the sash frame base profile 3 with the two firmly locked attachment metal profiles 5, 6 and the mounted glazing bead 8. figure 14 shows the connection with the glazing bead 8 enlarged. To mount the glazing bead 8, the glazing bead hook 21 is guided through the gap/glazing bead retaining groove 19 between the overhang 20 and the hook surface 18 and locked. The foot of the glazing bead hook 21 is then clamped between the projection 20 and the hook surface 18 while pressure is exerted on the glazing bead 8 by the glazing, not shown, via the seal, not shown, so that the glazing bead 8 is firmly seated. The horizontal Alignment of the hook surface 18 and the projection prevents a vertical movement of the glazing bead 8. The fastening of the glazing bead 8 is integrated into the composite frame in an elegant and stable manner in the manner according to the invention; the gap / glazing bead holding groove 19 through which the connection is made is covered after assembly. The exemplary embodiment shows that the outer surface 17 of the inner attachment metal profile 6 just merges into the right-hand outer surface of the glazing bead 8 .

figure 8 shows the frame base profile 4 with the two firmly locked attachment metal profiles 5, 6 and the mounted locking part 9 with the screw 10 for firm attachment to the frame base profile 4. figure 16 shows the fixation of the closing part 9 enlarged. Here it can be seen that the sleeve 23 is guided through the gap 19 . In the hook 15 there is a hole, not shown, so that the screw 10 engages in the plastic base profile 2 . The horizontal orientation of the hook surface 18 prevents the screw 10 from slipping off to the side, particularly when the screw 10 is inserted at an angle. Here, too, the gap/glazing bead holding groove 19, through which the locking part 9 is fastened, is optically concealed when viewed from the inside of the building. The exemplary embodiment shows that the outer surface 17 of the inner facing metal profile 6 just merges into the right-hand outer surface of the closing part 9 .

figure 9 shows a plastic basic profile 2, which consists of two plastic partial profiles 3,4. In the plastic part profile 3 is the casement base profile 3 from the figures 1 , 3 , 5 and 7 . In the plastic part profile 4 is the window frame base profile 4 from the figures 2 , 4 , 6 and 8th . The two plastic partial profiles 3, 4 have the same width and are connected to one another via a coupling profile 7. For this purpose, the two plastic partial profiles 3, 4 each have a groove on the top and bottom. The side walls the grooves in turn have locking notches into which locking hooks of the coupling profile 7 engage.

figure 10 shows the plastic base profile 2 figure 9 with two intent metal profiles 5, 6, which differ from the intent metal profiles from the Figures 1 to 8 differ in that they are significantly higher. The intent metal profiles 5, 6 each have a hook 15 in the upper area, a locking lug 11 in the middle area and a locking lug 11 in the lower area. Here, too, the inner facing metal profile 6 has a hook 15 with an installed position (cf figure 11 ) horizontal hook surface 18.

As described above, the two facing metal profiles 5, 6 are connected to the plastic base profile 2 by first putting the hooks 15 around the bulges 16 of the upper plastic part profile 4. The two attachment metal profiles 5, 6 are tilted with the top inward towards the plastic base profile 2.

Subsequently, the facing metal profiles 5, 6 are firmly connected to the plastic base profile 2 by rotating the respective outer facing metal profile 5 counterclockwise, as a result of which the upper latching hook 11 slides along the slope 14 in front of the undercut 12 of the upper plastic part profile 4 and then this latching hook 11 engages in the aforementioned undercut 12, while in each case the lower latching hook 11 slides along the slope 14 in front of the undercut 12 of the lower plastic part profile 3 and then this latching hook 11 engages in the undercut 12 of the lower plastic part profile 3.

The same happens on the other side, on which the inner end metal profile 6 is rotated clockwise.

figure 11 shows an inventive, fully assembled composite profile 1 with the plastic base profile 2 from two plastic part profiles 3, 4, coupling body 7 and two attachment metal profiles 5, 6. Here, too, there is a gap 19 between the inner attachment metal profile 6 and the plastic part profile 4 above the hook 15. In the case of the figure 11 Composite profile 1 shown is a casement profile. A glazing bead 8, not shown, can be inserted through the gap 19 and locked as previously described for the one-piece plastic base profiles 2.

figure 12 shows an associated blind frame profile. The fully assembled composite profile 1 has a plastic base profile 2 made of two identical plastic part profiles 4, coupling body 7 and two attachment metal profiles 5, 6. The plastic part profile 4 is the window frame base profile 4 from the figures 2 , 4 , 6 and 8th . In the embodiment of figure 12 the two attachment metal profiles 5, 6 are connected only via the hooks 15 to the bulges 16 of the upper plastic part profile 4 and via the latching hooks 11 in the lower area to the undercuts 12 of the lower plastic part profile 4. There is also a gap 19 between the inner attachment metal profile 6 and the plastic part profile 4 above the hook 15. A locking part 9, not shown, can be inserted through the gap 19 and locked as previously described for the one-piece plastic base profile 2.

From composite profiles 1 according to figure 11 8 window sashes can be produced in conjunction with other parts such as the glazing and glazing beads. From composite profiles 1 according to figure 12 In conjunction with other parts, matching blind frames can be manufactured so that a complete window can be built in total. It is manufactured by assembling and connecting composite profiles 1.

The attachment metal profiles 5, 6 are often aluminum profiles produced by extrusion.

The invention is not limited to the exemplary embodiments and can include further variants with the features described in the application. According to the invention, certain features can also be omitted if the combination of features falls under the protection of a patent claim.

The hook 15 can be attached below instead of above and the locking lug 11 above.
