EP3643867B1 - Frame for doors and windows with additional components - Google Patents

Description

The invention relates to a frame for doors and windows with additional components, with the features of the preamble of claim 1.

Windows with manual operation by means of a handle are part of everyday life. Conventional windows consist of a frame and a casement. The term "frame" refers to the frame that is firmly connected to the outer wall. In this frame there are then one or more casement frames which can be opened.

At the same time, windows fulfill a wide range of tasks for people and buildings. They are a design element of the house and their primary function is to connect the indoor and outdoor space, allow the highest possible incidence of light and create a healthy and comfortable living environment. For a high level of comfort of use, window opening types are also of great importance. Window opening types are determined according to the opening method. A distinction is made between fixed-glazed windows, side-hung windows, tilt windows, turn-tilt windows and sliding windows.

However, this manual drive principle for windows, which has been tried and tested for decades, cannot meet the increasing demand for automation in buildings. To increase living comfort, security To improve and achieve higher energy efficiency, automation on the windows has become indispensable in the course of advancing home automation.

In order to enable the motorization of window sashes, the installation of sensors for the control function and the motorization of roller shutters and sun protection products, the windows must be provided with their own power supply and integration into the control system during installation. In the areas of sun protection and sensor control, there are also radio-based solutions for easy retrofitting.

So far, conventional window frame profiles have not offered any installation space for additional electrical drive units. In particular, commercially available window frames do not provide any space for this. Subsequent conversion from manual to electrical operation has so far not been possible at all or only with great effort.

DE102008017325 shows the generic features of claim 1.

From the DE 297 06 637 U1 a motor-driven tilt and turn window is known in which a drive motor for actuating coupling fittings of a tilt and turn window is provided within the window frame. If required, the window sash is moved into the ventilation or open position as well as into the closed position by means of a driven adjusting gear. The housing of the drive unit is fully integrated in the frame profile. The actuators must therefore be installed in the profiles of the window before the window is manufactured. This concealed installation of the drives and the drive housing has the disadvantage that in the event of a defect in the drives, dismantling is no longer easily possible. In such a case, either only the entire window can be exchanged, or the relevant component has to be removed, in which case the frame must also be dismantled and the individual frame legs dismantled.

In the aforementioned designs of a window or a door, additional elements are used, for example, in that part of the frame profile is milled out, and so a receiving recess is made. However, since the known frame profiles have a large and central hollow chamber into which a metallic reinforcement profile, in particular a square tube made of steel, is inserted, manual reworking inevitably leads to the severing of the hollow chamber and the reinforcement profile stamped therein. As a result, the thermal insulation, rigidity and strength of the plastic frame deteriorate. Opening the steel chamber harbors the risk that moisture can penetrate. As a result, rust forms as a corrosion product. Furthermore, the manual processing of the reinforcement chamber is extremely difficult, since the reinforcement steel is directly surrounded by PVC material in the installed state. For the processing of the material combination of steel and PVC, sawing and milling tools must be used that are suitable for steel as the harder material, but which on the other hand do not achieve good results when processing PVC as the softer material.

The object of the invention is thus to improve a frame profile of the type mentioned at the beginning in such a way that additional elements can still be installed while maintaining the intact steel reinforcement.

This object is achieved by a frame profile with the features of claim 1.

• Die Außenabmaße des Querschnitts bleiben unverändert, wodurch die Kompatibilität zu den bisherigen Profilen vom gleichen System erhalten bleibt.
• Geschaffen wird ein Profil, das während der Fertigung des Fensters, aber auch nachträglich, also im eingebauten Zustand des Fensters, bearbeitet werden kann.
• Das Blendrahmenprofil nach der Erfindung ermöglicht, dass ein eingebautes Fenster jederzeit vom manuellen auf den elektrischen Betrieb nachgerüstet werden kann und auch wieder reversibel ist. Es wird also eine universelle Blendrahmenkonstruktion geschaffen, die eine manuelle Bedienung des Fensters ermöglicht und die jederzeit durch teilweises Befräsen, ausschließlich im Kunststoff des Blendrahmenprofils, zur Gewinnung eines Bauraums dient, in den Zusatzkomponenten, vorzugsweise zur Automatisierung und Elektrifizierung, aber auch zur Lüftung, eingesetzt werden können.
• Eine Rückführung in ein händisch angetriebenes Fenster ist immer möglich.
• Ein Austausch der Motoreinheit bei eintretendem Defekt ist ohne großen Aufwand schnell und unkompliziert ausführbar. Besonders vorteilhaft ist, dass der Bauraum geschaffen werden kann, ohne dass die Stahlkammer eröffnet oder bearbeitet werden muss.
• Sowohl eine Umrüstung auf einen elektrischen Fensterbetrieb ist jederzeit möglich, als auch ein unkomplizierter Austausch der Zusatzelement im Falle einer Reparatur.

The advantages of the frame profile according to the invention are as follows:

• The external dimensions of the cross-section remain unchanged, which means that compatibility with the previous profiles from the same system is retained.
• A profile is created that can be edited during the manufacture of the window, but also afterwards, i.e. when the window is installed.
• The frame profile according to the invention enables a built-in window to be upgraded from manual to electrical operation at any time and also to be reversible again. A universal frame construction is thus created that enables manual operation of the window and which is used at any time by partially milling, exclusively in the plastic of the frame profile, to gain space, used in the additional components, preferably for automation and electrification, but also for ventilation can be.
• A return to a manually operated window is always possible.
• An exchange of the motor unit in the event of a defect can be carried out quickly and easily without great effort. It is particularly advantageous that the installation space can be created without the steel chamber having to be opened or processed.
• Both a conversion to an electric window operation is possible at any time, as well as an uncomplicated exchange of the additional elements in the case of a repair.

Essential to the invention is the change made to the arrangement of the cavities in the profile cross-section compared to conventional frame profiles. The decisive measure is the hollow chamber, which is used to accommodate the metallic reinforcement profile and thus to stabilize the plastic window frame, moved to the outside that a freely configurable cross-sectional area is created on the inside of the window frame.

The size of the hollow chamber with the internal steel reinforcement remains completely unchanged in terms of its dimensions. In this way, new space is gained on the inside of the window frame, which has to fulfill several functions and is structurally designed according to its use. These functions include providing a glazing bead groove in the inner wall area to allow for fixed glazing with the frame profile to maintain according to the invention. Furthermore, between the inner wall and the hollow chamber wall for the reinforcing hollow chamber, there must be at least one cross-sectional section that extends completely over the vertical height of the cross-section and is closed on all sides, which serves for thermal insulation. Finally, the strike plates must be mounted on the frame by means of screws, with screws arranged outside the glazing bead groove.

This results in a hollow chamber arrangement in at least two vertical hollow chamber gaps in the central region. Each hollow chamber gap extends between the bottom web and the cover center web. Due to the vertical extension, each hollow chamber gap can be opened individually by milling from the cover center web without damaging the adjacent hollow chamber walls or the inner wall.

At least one hollow chamber gap has a further horizontal transverse web between the bottom web and the cover center web in order to form an abutment for screws to be introduced from above.

Preferably, at least one hollow-chamber gap arranged laterally next to the glazing bead groove is provided with several additional transverse webs which form a screw channel for the strike plate to be attached to the top. These additional bars provide material for the fastening elements for stable anchoring and allow flexible positioning of the screws, depending on the different types of strike plate.

As an alternative or in addition to webs, cams that are extruded on can also be provided which, with their material-reinforcing effect, offer the screws additional material in order to cut and / or jam there.

In a coordinated profile system with a frame and sash profile, it is advantageous if the possible receiving area in the frame profile is exactly below a fitting receiving groove on the outside of the sash profile, the so-called Euro groove, is arranged. This makes it possible to accommodate additional components in the frame profile, which are arranged below the Euro groove, so that from here it is particularly easy to influence the common fittings on the sash in order to functionally interact with them. It is possible, for example, to make locking plates displaceable by means of electrical actuators. In this way, for example, a window that has previously been locked manually using conventional turn-tilt fittings can be electrically unlocked without having to arrange drives in the sash.

In the receiving space to be created in the frame profile according to the invention, for which the internal hollow chambers are opened by milling off an inner part of the central cover web, another cavity below the drive unit will serve as a conduit. This channel can extend over all four frame spars of a window, is completely continuous and enables the laying of cables or other accessories, while recesses are only made selectively in the frame profile for drive units and the like. Access to the conduit is from a selectively created receiving space. In the course of the conduit, no material has to be removed from the cross section.

Figure 1 shows a sash frame system in cross section with a frame profile 100 according to the invention, as it is shown in the assembly. The sash frame system consists of a sash profile 200 and the frame profile 100, each of which is designed as a hollow-chamber plastic profile. Both profiles each have a metallic reinforcement profile 53, 203 in at least one of their hollow chambers 52, 202.

The sash is movably connected to the frame. Between the sash profile 200 and the frame profile 100, three sealing planes are formed, each of which is formed by sealing strands extruded onto it.

The overall depth corresponding to the cross-sectional width of the frame profile 100 is preferably 82 mm, but can also be used for other overall depths, so that it can be integrated into existing sash systems. In this exemplary embodiment, the cross-sectional width of the profile system is preferably selected so that the gap width in the outer sash contact area for an outer window frame seal 17 is approximately 3 mm to 5 mm and in the inner sash contact area for an inner window frame seal 18 it is approximately 6 mm to 10 mm. Such gap widths, which are larger in comparison to conventional frame profiles, allow pressure-sensitive sensor strips to be integrated into the seals 17, 18, or they can be used instead in order to be able to automatically cancel a motorized closing movement of the sash if foreign bodies or limbs are between the frame profile 100 and the sash profile 200 are jammed.

• einen Außenwandbereich 10 mit einer Außenwand 11, die im oberen Bereich Teil eines Blendrahmenüberschlags 19 ist;
• einen Mittelbereich 50 mit einer großen Hohlkammer 52 und dem Verstärkungsprofil 53 darin;
• einen Stegbereich 30, vom dem ein oberer Teilbereich als Aufnahmebereich 40 ausgebildet ist, so dass er entfernt werden kann, um Zusatzeinrichtungen innerhalb des Profilquerschnitts unterbringen zu können und
• einen Innenwandbereich 20 mit einer Innenwand 11.

The frame profile 100 according to the invention is divided in cross section. from left to right in:

• an outer wall area 10 with an outer wall 11 which is part of a frame cover 19 in the upper area;
• a central region 50 with a large hollow chamber 52 and the reinforcement profile 53 therein;
• a web area 30, of which an upper sub-area is designed as a receiving area 40, so that it can be removed in order to be able to accommodate additional devices within the profile cross-section, and
• an inner wall area 20 with an inner wall 11.

In Figure 2A and Figure 2B the frame profile 100 is shown in each case alone in cross section in order to be able to explain further details.

How Figure 2A shows, the profile is delimited in the middle area 50 upwards by a cover center web 51 and downwards by a bottom web 54. A vertical web with a receiving groove for a central seal 56 adjoins the left edge of the cover center web 51. The hollow chamber 52 and the reinforcement profile 53 are arranged centered under the central seal 56.

As is known, the metallic reinforcement profile 53 is used to mechanically stabilize the frame profile 100, which is made of plastic such as, in particular, hard PVC.While in conventional frame profiles the hollow chamber with the reinforcement profile is preferably positioned closer to the interior, the inventive position of the hollow chamber 52 is centered under the central seal 56 and thus outside of the web area 30 and the receiving area 40. With this new spatial arrangement the area between the large hollow chamber 52 and the inner wall area 21 has become significantly larger than with conventional frame profiles.

At the inner upper corner of the frame profile 100, a glazing bead groove 27 is formed between the inner wall 21 and the cover center web 51, which makes it possible to use the frame profile 100 for fixed glazing and other fillings. In addition, the glazing bead groove 27 often serves as a receiving groove for fittings such as striking plates.

The web area 30 is laterally connected directly to the inner wall 21 and has three hollow chamber walls 32, 33, 34 arranged parallel to it, so that between the inner wall 21 and the hollow chamber 52, which is delimited by the hollow chamber wall 34, three vertical hollow chamber gaps 31.1, 31.2 , 31.3 are formed.

Parts of the hollow chamber gaps 31.1. 31.2, 31.3 can be removed without impairing the stability of the frame profile 100.

The inner wall 21 is connected to the first hollow chamber wall 22 by at least one connecting web 26, forming at least two hollow chambers 25.1, 25.2, with at least one further hollow chamber 25.3 being formed between the first and second hollow chamber walls 32, 33.

The outer wall 11 and inner wall 21 have a wall thickness of, for example, 2.8 mm and thus form the thickest and most dimensionally stable wall webs. The cover center web 51 and the bottom web 53 have a wall thickness of 2.5 mm. The outer and inner walls 11, 21 are arranged parallel to one another. Covering means and bottom webs 51, 53 are also largely parallel to one another. The cover center web 53 is at the transition and forms a drainage groove 16. In two places there are grooves for a frame seal 17 and a center seal 56. At the upper end of the inner wall area 20 there is a glazing bead receiving groove 27 which, in the embodiment shown, is used at the same time to position and fasten a strike plate.

The frame profile 100 is framed by the circumferential, outwardly delimiting webs, namely an outer wall 10, a cover center web 51, an inner wall 21 and a bottom web 54, so that a closed profile jacket is formed.

For further details of the web region 30, in particular in the left hollow chamber gap 31.2, see Figure 2B referenced. In the embodiment shown, the hollow chamber wall 33 and a parallel hollow chamber wall 34 are connected to one another by four horizontal webs 36.1, ... 36.4 one above the other, forming four hollow chambers 35.1, ..., 35.4. In this variant, each of the four hollow chambers 35.1, ..., 35.4 has a ratio of chamber width to chamber height of 2: 1. The lower web 36.4 and the bottom web 54 form a somewhat higher hollow chamber 35.5 between them. The hollow chamber 25.2 has the same height.

Figure 3 shows the frame profile 100 according to the invention with a representation of the fastening of a strike plate 60 on the frame profile 100. Here it can be clearly seen how a fastening element 37 pierces the cover center web 51 and the webs 36.1 ... 36.4 and is firmly anchored in them. The webs 36.1 ... 36.4 in the left hollow chamber column 31.2 thus fulfill a double function: on the one hand, they connect the hollow chamber walls 33, 34 to one another, and on the other hand, the webs 36.1 ... 36.4 in the left hollow chamber column 31.2 of the central area 30 form a screw channel for fastening the Striking plate 60.

The frame profile 100 offers the possibility of accommodating additional elements in cross-section. Figure 4 shows a possible milling area 44 in the cross-section of the frame profile 100. Due to the inventive laying of the large hollow chamber 52 with an inserted reinforcement profile 53 To the outside down to below the central seal 56, the inner wall area 20 and the web area 30 thus offer enough removable cross-sectional area to form a receiving area 40 without, however, having to touch the hollow chamber 52 with the metallic reinforcement profile 53.

The frame profile 100 can be machined from the inner side of the cover center web 51 along the milling area 44, so that a recess is created which serves as a receiving area 40 for additional elements. An outer part 51.1 of the cover center web 51 and the vertical, outer hollow chamber wall 34 are completely retained with their respective wall thicknesses.

The milling tool is moved along the outer hollow chamber wall 34 and the inner milling edge 44.1 in the horizontal plane by cutting, to a depth of the upper web 36.4. The depth of the milling can vary, because each web 36.1, ... 36.4 can optionally offer an additional storage area for additional elements that can be used. The milling area 44 can be designed symmetrically or asymmetrically in relation to its cross section.

The webs below in the receiving area 40 do not necessarily have to serve as a support surface, since z. B. rest a drive motor or other additional parts by means of fastening straps on the cover center web 51 and can be screwed tightly there.

Figure 5 shows the completely milled frame profile 100 with the receiving area 40. The receiving area 40 is rectangular in cross section in the embodiment shown, still open at the top and partially open to the bottom web 54. The original hollow chamber 25.3 is due to the removal of the cover center web 51 and the two upper sections of the hollow chamber walls 32, 33 open and has thus become a groove 42. The lower boundaries of the receiving area 40 are formed by the connecting webs 36.4 and 26 and close the remaining hollow chambers below them 35.5 and 25.2. Between the two hollow chambers 35.5 and 25.2, the receiving area 40 has the groove 42, which functions as a conduit. In unprocessed frame sections, the hollow chamber 25.3 in the middle hollow chamber gap offers generous space for cabling or bus systems. In particular, excess cable lengths or other lines can be accommodated in the existing installation space. The length of the processing area corresponds to the length of the additional component that is to be integrated in the outer frame.

Figure 6 shows the receiving area 40 with an inserted drive unit 43. The maximum width of the receiving area 40 is approximately 1/4 to 1/2 of the cross-sectional width of the frame profile 100, which extends between the hollow chamber wall 34 and the inner wall 21. An electrical line 45 runs in the line duct 42.

Figure 7 is a perspective view of the frame profile 100 with the receiving area 40 and with an attached strike plate 60 with borehole 61 for fastening with a screw 61 in the web area 30. This figure shows that the insertion of a drive unit 43 into the receiving area 40 can be accomplished in an uncomplicated manner. The replacement of a drive unit is also easy to handle. The accommodation of cables in the conduit 42 is easy to carry out, which is advantageous both during initial assembly and in the event of repairs, since this area is easily accessible even when the frame profile 100 is installed.

Figure 8 shows a perspective view of the frame profile 100 with inserted drive unit 43 and fastening tabs 46. The drive unit 43 is inserted from above into the receiving area 40 and is screwed to the fastening tabs 46 with screws and is held above it on the cover center web 51.

Figure 9 shows a further embodiment of a frame profile 100 ', which is only in one detail in the area of the left cavity gap 31.1, which forms the screw channel, differs from the embodiment described above. The third transverse web 36, '3, counted from above, has cams 38 extruded on both sides in order to guide and anchor a screw 61 in the screw channel (see FIG Fig. 3 ) to improve.
