DESCRIPTION WINDOW/DOOR SYSTEM

The invention relates to a window/door system with at least one installation frame and a window field laterally surrounded by the latter, wherein the installation frame has outer and inner frame parts arranged at a distance from one another and a heat-insulating material arranged between them.

Such window/door systems are known from practice. The frame parts are usually made of extruded aluminum. This offers a high degree of design and construction flexibility. A heat-insulating material is arranged between the shell-shaped frame parts as a thermal separation. In addition to the extruded aluminum shells, cold-profiled metal shells made of steel and stainless steel are also known for the frame parts. These have significantly better static properties than aluminum frame parts. However, steel frame parts have more problematic corrosion protection and significantly reduced design and construction flexibility. With stainless steel frame parts, the significantly higher price level must also be taken into account.

The invention is based on the object of improving window/door systems of the type mentioned at the outset in such a way that, with equally good static properties, less material is required for the frame parts and good thermal separation of these parts is possible.

This object is achieved in connection with the features of the preamble of claim 1 in that the heat-insulating material is designed in the form of a frame-shaped separating part which laterally surrounds the window field and to which the outer and inner frame parts, which are essentially formed from a flat profile, are fastened as structural parts, in particular in a detachable manner.

According to the invention, the separating part made of heat-insulating material is not only used for thermal separation, but also as a frame part with its own static properties and to stabilize the window/door system. No complexly formed metal shells made of extruded aluminum or cold-formed steel or stainless steel are required as structural elements for the outer and inner frame parts. Instead, the structural elements are essentially made of a flat profile that is connected to the separating part and together with it surrounds the window field.

The structural components can be optimized with regard to the statics required by the construction site (moment of inertia, section moduli, etc.) and can also be adapted to the climatic ambient conditions (salt air, industrial gases, etc.) by choosing suitable materials.

The separating part at least completely takes over the function of thermal insulation between the outer and inner frame parts.

In order to be able to build other window/door systems in addition to a fixed field as a window field with just one installation frame, a pivoting frame in which the window field is arranged can be pivoted on the installation frame. This makes it possible to create windows with different window sashes, such as pivoting, reversible or folding sashes. The same applies to door systems, where the actual door can be formed as a pivoting element with a corresponding pivoting frame and a window field held by this. The window field can have glazing in the form of a single, profile, double, insulating glass pane or the like. If transparent window fields are not desired, this can also be formed by a plastic panel or the like, whereby a decorative part forms or can be a covering for the panel.

According to the invention, the swivel frame and the installation frame are constructed essentially the same, comprising at least structural parts and a separating part. Variations in the construction of the swivel frame and installation frame arise, for example, because the corresponding parts of these frames have functional deviations.

■ f »t

In addition to its thermal insulation function and its static properties, the separating part can also serve as a support for other equipment or accessories, such as seals, stops, fittings or the like. These are in particular detachably attached to the separating part.

In order to enable good force introduction between structural parts and separating parts and variable possibilities for mutual fastening, the structural part can lie essentially flat on the inner and/or outer sides of the separating part and be fastened there.

Since steel systems have advantages over aluminum systems in terms of mechanics and stability, the structural part can be made from a steel or stainless steel flat profile. Such flat profiles are mass-produced steel products and have, for example, a square or rectangular and possibly also rounded or oval shape corresponding to the outline of the window field.

In order to be able to attach the installation frame to a wall or the like in a simple manner, a structural part can be designed as an angle, Z or T profile, with one leg resting at least partially on the separating part and the other leg on the wall or the like. The legs can be attached to the separating part or to the wall by screwing or the like.

In order to allow at least the same design flexibility in steel systems as in aluminum systems, a decorative part can be applied to an outside and/or inside of the structural part and/or separating part. It is of course also possible for such decorative parts to be used to cover other equipment and fittings of the window/door system, if desired.

One example of such a decorative part is a decorative sheet. This can be made from satin-finished, highly polished, painted, textured or similarly prepared and processed steel sheets.

In addition to the design as a decorative sheet, a design as a decorative film is also conceivable. This can be made of a material other than steel or stainless steel, such as brass, bronze, wood or the like. Of course, decorative parts can also be combined with one another depending on requirements or wishes, such as a decorative sheet made of stainless steel on the outside of a window and a decorative film made of wood on the inside of the same window. Other combinations are obvious.

If a smooth and polished outer surface is desired for the window, a decorative part can be dispensed with if the corresponding structural part has a ground or polished outer surface. In this case, the structural part is essentially designed as a decorative part, at least on its visible surface.

There are many variations in the design and shape of the separating part. For example, the separating part can have recesses, holes, grooves, channels, steps
and/or other elements that enable frictional, positive
and/or force-fitting arrangement of the other equipment and/or accessories including structural and decorative parts. Furthermore, the separating part can be
Thickness of the glazing arranged in the window field with appropriate width. It is also possible that the separating part is designed from the outset for use with glazing of different thicknesses. Holding profiles,
Seals, structural parts and the like can be variable in this context
be designed to adapt to different glazings, variations in glazing thickness, etc.

To save material and improve thermal insulation, the separating part
have at least one cavity formed in its interior, which in particular forms an annular cavity extending along the separating part.

In order to be able to drain any moisture that may have penetrated into the window field to the outside, drainage holes can be made in the separating part and/or structural part and/or decorative part
be trained.

In the case of a pivoting window sash, a contact leg is usually provided on at least one frame part in the known window/door systems, which is in contact with a corresponding seal when the window is closed. According to the invention, the separating part can be designed as one piece with such a sealing contact leg. This eliminates the need for a separate formation of such a leg on the metal profiles or, for example, an additional attachment of such a leg to the separating part.

In order to enable a separating part with sufficient stability and easy formability while at the same time being simple to manufacture, the separating part can be made from a plastic material, in particular one reinforced with glass fiber. Preferred plastic materials are polyester resin, phenolic resin, polyamide or the like.

In order to easily weld metal frame parts to the plastic separating part, a metal profile can be embedded in or attached to the separating part and/or in the separating part. The metal frame part can be easily welded to this.

In order to use metal frame parts only where necessary, at least one additional retaining profile made of a heat-insulating material can be attached to the separating part, in particular in a detachable manner. In addition to a detachable attachment, a positive and/or non-positive connection between the two can also be made. The retaining profile is also usually made of a glass-fiber-reinforced plastic material.

One arrangement for such a retaining profile is that it extends from the separating profile in the direction of the glazing and is designed at least as an edge cover of the window field or the glazing. The retaining profile can serve as a glass retaining strip, panel retaining strip and the like.

To hold the holding profile on the separating part, a groove in the separating part or, for example, a receptacle (step) between the separating part and a structural part can be provided, in which a clamping foot of the holding profile is held in a particularly form-fitting manner. In order to be able to hold the clamping foot securely, it can have inclined side surfaces, which are, for example, at an angle of 5° to 20° to a vertical

are inclined. Corresponding side surfaces of the groove or the above-mentioned receptacle can be inclined at similar angles.

Since the retaining profile and possibly also the separating profile can be visible from the outside, it can be considered advantageous if the retaining profile and separating profile have a decorative part at least on their visible surfaces.

In order to easily determine the closing position of, for example, tilt and turn windows and at the same time to maintain a good seal between the installation frame and the pivot frame, the structural parts on the pivot and installation frame can be arranged to overlap each other.

In order to further improve the sealing in this context, as with other windows or doors, seals can be arranged between the retaining profile and/or structural part and the window field and/or separating part.

In order to prevent liquid running down from the glazing from entering a gap between the installation frame and the pivoting frame when the window is closed or not completely closed, the decorative part and/or structural part and/or retaining profile can have a drip edge that protrudes outwards. This is arranged in particular along the lower edge of the glazing on the pivoting frame and directs the liquid away from the pivoting or installation frame. The drip edge can also be designed as a separate component.

It goes without saying that windows or doors with posts and/or transoms can also be constructed from at least a structural part, a separating part and/or a decorative part, as described above.

We have already mentioned a detachable fastening between the different parts. It should be noted that essentially all common fastening technologies can be used to connect the separating part, structural part and decorative part and also the retaining profile. Examples include gluing the structural part and separating part in the area of their flat, adjacent sides. As an alternative to gluing, or at the same time as gluing, these two parts and other parts can be screwed together.

Welding the structural parts or the other parts to the separating part has already been mentioned in connection with the embedded or attached metal strips. The decorative parts can preferably be glued on. Of course, it is also possible to screw them on, weld them on or anchor them to the corresponding part in a form-fitting or friction-fitting manner using appropriate shaping (bending or cold profiling). Screws for attaching the structural parts to the separating part can be screws suitable for GRP, for example self-tapping. Countersunk screws, flat head screws or the like can also be used. It is also possible for the screw head itself to be designed as a decorative part, so that a separate decorative part in this area can be dispensed with.

In the following, advantageous embodiments of the invention are explained in more detail with reference to the figures attached to the drawing.

The following figures show a horizontal section through the posts or frame beams of a window system. An analogous structure applies to door systems. In all figures, the same parts are designated with the same reference symbols and some are only explained in connection with one figure.

Figure 1 shows a first embodiment of a window system 1 with a fixed element window field 3. The window field 3 is a double insulating glass pane which is surrounded along its circumference by a mounting frame 2.

The installation frame 2 has two lateral structural parts 4, 5 as outer and inner frame parts, respectively, which are formed from a flat profile 8. A heat-insulating separating part 7 is arranged between these two flat profiles 8. This has an undercut anchoring channel 24 on its side facing away from the window field 3. Two holes 22 are arranged in the separating part 7 to the side of this channel, into which screws 39 are screwed for the detachable fastening of the structural parts 4, 5.

On its window side 30 facing the window field 3, the separating part 7 is essentially flat, with the window field 3 being supported in this flat area by support block 49. Two steps 40, 53 are formed in the separating part 7 to the side of the flat area. These steps 40, 53 each form a channel-shaped depression with the adjacently attached structural part 4, 5. A retaining profile 31 made of GRP or metal is inserted into one of these channels 53 (retaining profile channel), which is held in the channel by structural part 5. The opposite channel 40 (condensate channel) is used to collect and drain condensate.

The structural part 5 shown on the right in Figure 1 extends essentially over the height of the separating part 7, while the structural part 4 shown on the left in Figure 1 extends laterally to the window field 3. A seal 38 is arranged between this and the structural part 4.

On the outer sides 18 (see also Figure 2) of the structural parts 4, 5, foil-like or sheet-like decorative parts 17 are applied. These can be attached to the structural parts 4, 5 by gluing, for example. The decorative part 17 on the right-hand side according to Figure 1 can be designed, for example, as a decorative sheet 19, which also extends over a visible surface 32 of the holding profile 31 up to the seal 33 arranged between it and the window panel 3. It is also possible for the decorative part to be applied separately to the holding profile 31 and the structural part 5.

The free ends of the decorative part 17 are each arranged between the free end of the structural part 4 or the holding profile 31 and the seal 38 or 33.

Instead of being screwed together with screws 39, the structural parts 4, 5 can also be glued to the separating part 7 or they can be both glued and screwed.

Figure 2 shows a section similar to Figure 1. This embodiment differs in that it has a holding profile 31, which is made of a heat-insulating material. This holding profile 31 has a nose 41 pointing in the direction of the seal 33, which engages in a corresponding groove 47 of the seal 33. The free end of the decorative part 17 is also arranged in this groove.

As a further difference to Figure 1, the window panel 3 is designed with a greater thickness, wherein the nose 41 of the holding profile 31 protrudes correspondingly less in the direction of the window panel 3 compared to the corresponding holding profile 31 according to Figure 1.

Figure 3 shows a section analogous to Figures 1 and 2 through a window system with a pivoting frame 9. This makes it possible to create a tilt and turn window, for example.

The installation frame 2 has a modified separating part 7. This has a holding channel 54, in particular on its side facing the swivel frame 9, as well as two further channels with undercuts arranged laterally to this, in which seals 10, 37 are detachably held. The holding channel 54 is designed as a so-called Euro groove for receiving standardized fittings.

The structural part 5 of the swivel frame 9 is in contact with the seal 10 protruding to the right in Figure 3. This is constructed in a similar way to the installation frame 2 from structural parts 4, 5 and a separating part 7 arranged between them. The separating part 7 of the swivel frame 9 is additionally designed with a stop 11 and a recess 21 next to the channel 55 for accommodating further fittings or the like. The stop 11 is designed in one piece as a sealing contact leg 28 with the separating part 7. The inner seal 37 rests with a sealing lip on the sealing contact leg when the window is closed according to Figure 3.

The structural parts 4, 5 of the swivel frame 9 are also formed by flat profiles 8 and are connected to the separating part by means of screws. Analogous to Figure 2, a holding profile 31 made of a heat-insulating material is arranged in a step 53. This has a nose 41 which fits into a corresponding groove 47, see again Figure

2, the seal 33 engages. The holding profile 31 has a clamping foot 50 at its end facing the separating part 7, see also Figure 10, which is inserted in the step 53. This has obliquely running side surfaces 51, 52, see again Figure 10, wherein the step or clamping groove 53 has a correspondingly inclined side wall at least on one side. The angle of inclination of the sides can be the same or different and is preferably in the range of 5° to 25°.

Relative to the recess 21 opposite the stop 11, the separating part 7 has a further extension 56. This extends in the direction of the structural part 4 of the installation frame 2 and serves as a support for the structural part 4. The distance between the structural part 4 and the extension 56 is smaller than the distance between the structural part 5 of the swivel frame 9 and the structural part 5 of the installation frame 2, which prevents direct contact between these structural parts and possible damage to the decorative parts 17.

In Figure 3, the structural parts 5 of the pivot frame 9 and the installation frame 2 overlap. It is also possible for these to be arranged flush with each other, see for example Figure 7, with a corresponding gap being formed between them.

As already noted, decorative parts are attached to the outside or visible surfaces of the structural parts and the holding profile, for example in the form of a decorative sheet. Analogous to the previous figures, the decorative part 17 on the right-hand side according to Figure 3 can, for example, be divided into two parts, with one part only covering the structural part 5 of the swivel frame 9 and the other part covering the visible surface 32 of the holding profile 31. ₁

On the left side of Figure 3, a structural part or decorative part 17 with a drip edge 34 shown in dashed lines is shown on the structural part 4 as an alternative embodiment. Water running off the window panel 3 can drip down along this edge at a distance from the structural part 4 of the installation frame 2.

Figure 4 shows a section analogous to Figure 3 through another embodiment. This differs from the embodiment according to Figure 3 by a flush arrangement of the structural parts 5 on the right side of Figure 4. In addition

On the outside of the structural part 5 of the swivel frame 9, an outer plate 42 made of a heat-insulating material is arranged, which also covers the visible surface 32, see Figure 3, of the holding profile 31 to the outside. On an outside 43 of the outer plate 42, a decorative part 17 is arranged accordingly, which extends with its free end into the groove 47, see Figure 2, of the seal 33.

The outer plate 42 extends above the screw 39 which fastens the structural part 5 of the mounting frame 2 to the separating part 7.

Opposite the outer plate 42, a drainage hole 26 or 27 is arranged in both the separating part 7 of the pivoting frame 9 and the installation frame 2. Water that has penetrated between the window field 3 and the pivoting frame 9 can drain through this. Instead of a drainage hole 27 in the separating part 7, a corresponding hole can also be formed in the structural part 4 of the installation frame 2.

Figures 5 and 6 show various options for anchoring a mounting frame 2. Similar anchoring options also apply to mounting frames 2 of pivot, turn, top-hung or tilt-and-turn windows.

In Figure 5, the structural part 5, see also Figure 2, is angled. One leg 15 rests on the side of the separating part 7 and is detachably attached there by means of a screw. The other leg 16 extends at a right angle to the first leg 15 and can be attached to a wall or the like by means of a dowel 44 or the like. The angle profile 14 can also have other angles between the two legs, whereby an angle of 180° between the legs is also possible depending on the installation. Z or T profiles can also be used for the angle profile 14.

In Figure 6, the anchoring device is arranged centrally to the separating part 7. A stiffening profile 29 is embedded in the channel 24 and held there in a form-fitting manner by the undercut. This can be a wedge or eccentric profile that bridges the distance to the wall.

It is also possible for another flat profile, for example, to be connected to the metal profile 29 by screwing it on, which in turn can be fastened to the side next to the installation frame 2 by means of a dowel 44.

Corresponding decorative parts 17 are arranged both in the embodiment according to Figure 5 and in that according to Figure 6.

Figure 7 shows a partially shown horizontal section through a tilt and turn window with mullions and transoms.

The corresponding installation frames 2 are shown at the top and bottom of Figure 7 (see also Figures 3 and 4), which are constructed as mirror images of each other. For further description, please refer to Figures 3 and 4.

In contrast to the previously mentioned figures, in Figure 7, in the area of the posts 35, the structural part 5 on the swivel frame 9 is arranged flush with the structural part 5 on the installation frame 2. These structural parts do not overlap. A bar 36 is arranged centrally between the two posts 35. This has a separating part 7 between the two window fields 3 extending to the respective posts 35. The separating part essentially has a rectangular cross-section with steps 40, 53 formed in its corners, see for example Figure 1. In the steps (clamping grooves) directed towards an interior of the window system, holding profiles 31 are arranged on both sides. These engage with their lugs 41 in a groove of the seals 33 in the manner already described, see also Figure 3. Structural part 5 is arranged centrally between the two holding profiles and is fastened to the separating part 7 with a screw. A decorative part 17 is applied to the outer sides or visible surfaces of the holding profiles 31 and the structural part 5. In this context, the decorative part 17 can also be designed in three parts, with one decorative part being assigned to each holding profile as well as to the structural part 5. The fastening of the decorative part 17 can be carried out in the manner already mentioned by gluing or the like.

Structural part 4 made of a flat profile is arranged opposite structural part 5. This extends on both sides beyond the separating part 7 to the side of the window frames.

3. Between the structural part 4 and the window fields a seal 38 is arranged in the manner already described.

It should be noted that a similar structure with posts and bars is possible for the fixed field described in connection with Figures 1 and 2. This applies analogously to the overlapping structural parts on the inside of the window systems described in connection with Figures 3 and 4.

Figures 8 and 9 show further embodiments of separating parts 7, see also, for example, Figures 1 and 3. These differ in particular in the formation of cavities 25 in the interior of the decorative parts 7. These can extend in the manner of an annular cavity along the entire separating part 7 surrounding a window field 3.

It is also possible that only one cavity is arranged in Figure 8 and two separate cavities are arranged in Figure 9.

Figure 10 shows a further embodiment of a holding profile 31. This differs from the previously described embodiments in that a cavity 25 is also formed in the holding profile. In particular, the clamping foot 50 with inclined side surfaces 51, 52 is visible.

The cross-sectional shapes of the cavities 25 in Figures 8 to 10 are shown only as examples. Round or polygonal cross-sectional shapes are also possible.

Figures 11 to 14 show further embodiments for fastening structural parts to separating parts. These embodiments can be used as an alternative to screwing the structural parts or in addition to screwing, possibly in conjunction with gluing.

Figure 11 shows a positive connection in the form of a dovetail connection. Of course, the projections 48, which engage in an undercut of the structural part 4, can be designed as right-angled, step-shaped projections.

Figure 12 shows a molded and adhesive bonded connection, wherein the structural part 4, 5 is formed from a substantially C-shaped profile or special profile.

Figure 13 shows a molded and welded connection. A metal profile 29 is anchored to the separating part 7 and can be connected, for example, by welding points 46 to a flat profile 8 as a structural part 4, 5. It goes without saying that the metal profile 29 can have other shapes in addition to the shape shown, such as L- or T-shaped.

Figure 14 shows yet another embodiment of a molded and welded connection. A metal profile 29 has a slot into which the separating part 7 is inserted and held there. At the lateral ends of the metal profile 29, a substantially C-shaped flat profile 8 is welded to the metal profile as a structural part 4, 5 via welding points 46. It is also possible for the metal profile 29 to be approximately L-shaped on both sides of the separating part 7 and for the flat profile 8 to be designed without lateral arms.

Further embodiments of such connections are obvious in connection with the embodiments described.
