Definitions
- the invention relates to connections of miter sections of two abutting profiles which are used for windows, doors or gates for building and garage door closures, in which the profiles have at least one internal chamber which is used for the insertion of fastening elements.
- a door frame that consists of three main profiles and is mitered at the corners of the profiles and held together by L-shaped clips.
- the inside edges of the clips are serrated to engage the frame.
- a corner connection is described for a mitered version of the legs of a frame, in particular a split door frame or window frame with panels that are U-shaped in cross section and frame legs to be connected to one another at the leg ends with claws protruding into the miter area on the outside of the leg, which are said to be from the Tongues punched out of the frame legs and lying in the leg plane are formed with abutments, the tongues and their abutments being arranged offset from one another and their dimensions being such that when the frame legs are mounted, the tongues on one frame leg between the tongues and on the other frame leg intervene with a special fit.
- In the miter area there is at least one clamping piece at the corner U-shaped panel is releasably pressed in and the two frame legs can be clamped together at a 90° angle using the clamping piece.
- the corner connector is designed as a hollow body and has a U-shaped cross section, the opening of which points to the side in the direction of the axis of curvature.
- the central web is aligned transversely to the axis of curvature and is bent and angled in such a way that it is essentially flat.
- a door and window frame wherein a hinged door or window made of plastic material is formed in the frame elements which consist of a tubular section reinforced by web elements which divide the hollow elements into elongated, hollow chambers. Reinforcing members in the form of L-section corner connectors are inserted into these chambers, each of the frame members having, at least along a portion thereof, a box-like shoulder formation projecting from one side of the member to again provide storage surfaces.
- the impact surfaces have T-shaped grooves in which sealing strips are placed to seal between the sash and the sash.
- the corner connectors comprise two parallel strips with an L-section, which are connected along their length by crossbars, and whose legs are inserted into compartments of adjacent frame elements. The frame element is clamped into a C-shaped section.
- the FR 25 25 675 A1 discloses a frame made of straight square hollow profiles, which are connected at the corners by angled corner pieces.
- the corner pieces have a raised tongue on both legs, which ensures blocking within the profiles. These corner pieces are inserted into the ends of the hollow profiles.
- mastic is injected into the spaces between the components. To make it easier to inject the mastic, each section is cut at a certain angle, less than half the angle of the corner. This way a section of the corner remains free. A slot is formed in the corner piece into which the mastic is injected.
- a fitting for forming corner angles for connecting hollow profiles consists of two fitting parts provided with clamping elements in cavities in the hollow profiles DE 32 11 890 A1 be revealed. These are connected to one another via a web that has a weakened wall and they have locking elements which engage with one another when the fitting parts are relative to the weakened wall and fix the fitting parts in the desired angular position relative to one another.
- the fitting is made of sheet steel and the fitting parts are designed as a U-profile.
- the angled legs are cut like a slot in an extension of the wall weakening designed as a predetermined bending line, with the legs of one fitting part being pronounced in steps in an area adjacent to the separating slot by the measure of their wall thickness and in this area have the locking elements which interact with matching locking elements in the corresponding leg areas of the other fitting part in the bent position.
- the locking elements are provided with punched outs in the form of spring tongues.
- the object of the invention is to design a type of connection for mitred profiles of doors, gates and windows for building and garage door locks in such a way that no additional aids, e.g. in the form of screws or adhesives, have to be used, since such use is very is time-consuming and increases assembly costs. Furthermore, in addition to being cost-effective to produce, such a miter joint should also be essentially waterproof so that no moisture can get into the interior of the profiles from outside the miter joint.
- a fastening element for connecting two profiles, which are preferably designed as light metal profiles and at least one self-contained chamber inside have, a fastening element is proposed for connecting a miter area of two abutting profiles, which consists of two stable sections at an angle of 90 ° to one another.
- these sections of the fastening element are connected to one another in a non-positive and positive manner, preferably by spot welding. After inserting the fastening elements into the chambers of the profiles, they are no longer visible to the outside and the two profiles are connected absolutely flush with each other in the miter area. This is due in particular to the fact that the two fastening elements within the profiles to be connected are made of austenitic steel and are in contact with the inner chamber walls on all sides, so that displacement is excluded due to a snug fit.
- the fasteners are designed to create a precise connection for easy use in the manufacture of frames for doors, windows and gates.
- the fastening element has two clamping sections at an angle of 90° to one another. These clamping sections are designed in such a way that there is a dimensional match to the inner chamber walls without any play as a snug fit.
- the fastening elements have resilient sections. This is achieved by the fastening element being made from an austenitic chrome-nickel steel. Such steel does not rust and has high spring forces. Nevertheless, such steel can be easily formed, so that the mechanical properties, namely the spring effect, are retained even during cold forming. Such spring forces make it easy to compensate for existing tolerances.
- the assembly Can be carried out without tools because the fastening elements are simply pressed into the opposite chambers of the profiles.
- the clamping area of the fastening elements essentially consists of two opposing U-shaped sections made of a thin sheet of metal, which are connected to one another on one side in their backs by a substantially straight spacer section.
- the design of the longitudinal extension of the clamping sections depends on the size of the profiles to be connected and the loads.
- the width of the clamping sections is determined by the size of the chambers into which the connecting elements with the clamping sections are inserted.
- the fastening element can be manufactured inexpensively as a stamped and bent part; additional assembly aids are not required.
- the fastening element 3 is an angular component, the basic elements of which are the legs 5 and 6. These legs 5 and 6 are permanently connected to one another in a fastening area in a non-positive and positive manner, for example by a spot welded connection.
- the fastening element 3 has the same distance dimension in its distance sections on all opposite sides or sections, the outer walls 10, 11 of the legs 5, 6 are provided with an offset or a recess 12. This makes it possible for the distance dimension of the distance section 16 to also remain in the area of the connection of the two legs 5, 6.
- the fastening element 3 is a stamped and bent part, the angled legs 5, 6 are connected to one another via a radius 13 between the distance sections 16.
- clamping section 7 is formed by the parallel wall 14 and the outer wall 11.
- a further clamping section 8 is formed from the parallel wall 15 in conjunction with the outer wall 10.
- These clamping sections 7, 8 are immersed in the chambers 4 of the profiles 1, 2 during assembly. It goes without saying that the parallel walls 14 and 15 must also not extend beyond the distance section 16.
- the width of the clamping sections 7, 8 is virtually formed by clamping section widths 17, although on the open sides of the clamping sections 7, 8 the fastening elements 3 can be designed in such a way that a larger dimension than the dimension of the distance sections 16 is implemented here.
- the clamping sections 7, 8 make it possible for the clamping sections 7, 8 to be pressed into the corresponding chambers 4 of the profiles 1, 2 without any problems under a certain pressure.
- the clamping sections 7, 8 In order to be able to carry out better assembly, the clamping sections 7, 8 have bevels on the free leg ends in the form of an insertion aid. So that the clamping sections 7, 8 can maintain their precise fit within the chambers 4, the width and thus the end of the clamping sections 7, 8 is determined by the clamping section widths 17.
- the fastening element 3 were designed in the manner described above, a permanent force-fitting and positive fit within the chambers 4 would not be sufficiently ensured.
- the spreader 9 is designed in such a way that when the fastening element 3 is inserted into the chamber 4, this can only be achieved with a slight pressure. As a result, the spreader 9 is pressed towards the distance section 16 and at the same time its free end rests against the corresponding inner wall of the chamber 4.
- the spreader 9 completely prevents the fastening element 3 from being removed from a chamber 4, because if the fastening element 3 is attempted to be pulled out, the free protruding end of the spreader 9 would fall into the adjacent wall of the chamber 4 press in.
- the dimensional coordination of the clamping sections 7, 8 and the spacer sections 16 in conjunction with the spreaders 9 creates a very precise fastening element 3, which only needs to be pressed into existing chambers of the profiles 1 and 2 by external force without tools. This creates a tight seal between the profiles 1, 2 in the miter area, which also guarantees watertightness.
- the connection according to the invention of profiles in the miter area is a rigid coupling between the profiles 1 and 2 and the fastening element 3, which do not allow any relative displacement between them after assembly.
- the profiles 1 and 2 can consist of light metal profiles or plastic or a hybrid material or even steel and with the miter joints according to the invention for windows, doors and gates used as closures for buildings and garages.
- the distance sections (16) between the clamping sections (7, 8) can be of the same size or of different sizes.
- the clamping sections (7, 8) can also have the same or different lengths.

Die Aufgabe der Erfindung besteht darin, eine Verbindungsart für auf Gehrung geschnittene Profile von Türen, Toren und Fenstern für Gebäude- und Garagentorverschlüsse so auszuführen, dass keinerlei zusätzliche Hilfsmittel, z.B. in Form von Schrauben oder Klebstoffen, eingesetzt werden müssen, da eine solche Verwendung sehr zeitaufwändig ist und die Montagekosten erhöht. Des Weiteren soll gleichzeitig neben der kostengünstigen Herstellung auch eine solche Gehrungsverbindung im Wesentlichen wasserdicht sein, damit von außerhalb der Gehrungsverbindung keine Feuchtigkeit in das Innere der Profile gelangen kann.The object of the invention is to design a type of connection for mitred profiles of doors, gates and windows for building and garage door locks in such a way that no additional aids, e.g. in the form of screws or adhesives, have to be used, since such use is very is time-consuming and increases assembly costs. Furthermore, in addition to being cost-effective to produce, such a miter joint should also be essentially waterproof so that no moisture can get into the interior of the profiles from outside the miter joint.
Die Aufgabe der Erfindung wird durch die Merkmale des Anspruches 1 gelöst. Die sich an den Hauptanspruch anschließenden Unteransprüche geben eine weitere Ausgestaltung des erfindungsgemäßen Gedankens wieder.The object of the invention is achieved by the features of claim 1. The subclaims following the main claim reflect a further embodiment of the idea according to the invention.
Zur Verbindung von zwei Profilen, die vorzugsweise als Leichtmetallprofile ausgebildet sind und innen mindestens eine in sich geschlossene Kammern aufweisen, wird zur Verbindung eines Gehrungsbereiches von zwei aneinanderstoßenden Profilen ein Befestigungselement vorgeschlagen, das aus zwei stabilen, im Winkel von 90° zueinanderstehenden Abschnitten besteht. Bei bestimmten Ausführungen von Profilen, die beispielsweise einer starken Bewegungslast ausgesetzt sind, ist das Vorhandensein von zwei Kammern zur Erhöhung der Stabilität des Bauwerkes sinnvoll. Diese Abschnitte des Befestigungselementes sind untereinander kraft- und formschlüssig, vorzugsweise durch eine Punktschweißung, verbunden. Nach dem Einsetzen der Befestigungselemente in die Kammern der Profile sind diese nach außen hin nicht mehr sichtbar und die beiden Profile sind im Gehrungsbereich absolut bündig miteinander verbunden. Dieses ist insbesondere darauf zurückzuführen, dass die zwei Befestigungselemente innerhalb der zu verbindenden Profile aus einem austenitischen Stahl bestehen und allseits mit den Kammerinnenwänden in Kontakt stehen, sodass aufgrund eines Passsitzes eine Verschiebung ausgeschlossen ist.For connecting two profiles, which are preferably designed as light metal profiles and at least one self-contained chamber inside have, a fastening element is proposed for connecting a miter area of two abutting profiles, which consists of two stable sections at an angle of 90 ° to one another. For certain versions of profiles that are, for example, exposed to strong movement loads, the presence of two chambers makes sense to increase the stability of the structure. These sections of the fastening element are connected to one another in a non-positive and positive manner, preferably by spot welding. After inserting the fastening elements into the chambers of the profiles, they are no longer visible to the outside and the two profiles are connected absolutely flush with each other in the miter area. This is due in particular to the fact that the two fastening elements within the profiles to be connected are made of austenitic steel and are in contact with the inner chamber walls on all sides, so that displacement is excluded due to a snug fit.
Die Befestigungselemente sind zur Herstellung einer präzisen Verbindung so gestaltet, dass eine einfache Verwendung bei der Herstellung von Rahmen für Türen, Fenster und Tore ausführbar ist. Dafür weist das Befestigungselement zwei im Winkel von 90° zueinanderstehende Klemmabschnitte auf. Diese Klemmabschnitte sind so gestaltet, dass eine maßliche Abstimmung zu den Kammerinnenwänden ohne Spiel als Passsitz besteht. Um doch bestehende Toleranzen sowohl bei den Profilen als auch bei den Befestigungselementen ausgleichen zu können, weisen die Befestigungselemente federnde Abschnitte auf. Dieses wird dadurch erreicht, dass das Befestigungselement aus einem austenitischen Chromnickelstahl hergestellt ist. Ein solcher Stahl ist nicht rostend und weist große Federkräfte auf. Trotzdem ist ein solcher Stahl gut umformbar, sodass die mechanischen Eigenschaften, nämlich die Federwirkung, auch bei der Kaltverformung erhalten bleibt. Durch derartige Federkräfte ist ein Ausgleich von bestehenden Toleranzen einfach möglich. Ferner ist die Montage ohne Werkzeuge ausführbar, weil die Befestigungselemente einfach in die gegenüberliegenden Kammern der Profile eingedrückt werden.The fasteners are designed to create a precise connection for easy use in the manufacture of frames for doors, windows and gates. For this purpose, the fastening element has two clamping sections at an angle of 90° to one another. These clamping sections are designed in such a way that there is a dimensional match to the inner chamber walls without any play as a snug fit. In order to be able to compensate for existing tolerances in both the profiles and the fastening elements, the fastening elements have resilient sections. This is achieved by the fastening element being made from an austenitic chrome-nickel steel. Such steel does not rust and has high spring forces. Nevertheless, such steel can be easily formed, so that the mechanical properties, namely the spring effect, are retained even during cold forming. Such spring forces make it easy to compensate for existing tolerances. Next is the assembly Can be carried out without tools because the fastening elements are simply pressed into the opposite chambers of the profiles.
Der Klemmbereich der Befestigungselemente besteht dabei im Wesentlichen aus zwei gegenüberstehenden, aus einem dünnen Blech bestehenden u-förmigen Abschnitten, die einseitig in ihrem Rücken untereinander durch einen im Wesentlichen geraden Distanzabschnitt verbunden sind. Die Ausführung der Längserstreckung der Klemmabschnitte richtet sich dabei nach der Größe der zu verbindenden Profile und den Belastungen. Die Breite der Klemmabschnitte bestimmt sich hingegen aus der Größe der Kammern, in die die Verbindungselemente mit den Klemmabschnitten eingesetzt werden.The clamping area of the fastening elements essentially consists of two opposing U-shaped sections made of a thin sheet of metal, which are connected to one another on one side in their backs by a substantially straight spacer section. The design of the longitudinal extension of the clamping sections depends on the size of the profiles to be connected and the loads. The width of the clamping sections, however, is determined by the size of the chambers into which the connecting elements with the clamping sections are inserted.
Um jedoch einen nicht demontierbaren und insgesamt festen Sitz der Klemmabschnitte innerhalb der Kammern zu erzielen, befindet sich in jedem der Klemmabschnitte mindestens eine nach auswärts gerichtete Aufspreizung des bestehenden Materials. Die mindestens eine Aufspreizung wird in die Rückenpartie, d.h. in den Distanzabschnitt, eingebracht. Dadurch wird bei der Montage des Klemmelementes, d.h. beim Einsetzen in die Kammer, die Aufspreizung leicht zusammengedrückt. Die Aufspreizung ist mit ihrem offenen Bereich zu der Eckausbildung des Befestigungselementes gerichtet, dadurch wird beim Einsetzen die Aufspreizung gegen die Innenwand der Kammer als auch gegen das Befestigungselement als solches gedrückt. So entsteht ein Befestigungselement, das nicht wieder aus der Kammer herausgezogen werden kann. Eine solche Nichtdemontierbarkeit garantiert auch gleichzeitig einen sicheren und festen Sitz der Klemmabschnitte innerhalb der Profile. Die vorbeschriebene Verwendung von nicht sichtbaren Befestigungselementen, nach der Zusammenfügung von zwei Profilen im Gehrungsbereich, wird ohne Bohrungen und Schraubverbindungen in den Profilen wasserdicht ausgeführt. Diese Vorgehensweise verkürzt die Montagezeiten und steigert die Qualität der Profilverbindungsarbeiten bei Massenprodukten wie Tore, Türen oder Fenster.However, in order to achieve a non-demountable and overall tight fit of the clamping sections within the chambers, there is at least one outward spreading of the existing material in each of the clamping sections. The at least one spreader is introduced into the back area, ie into the distance section. As a result, the expansion is slightly compressed during assembly of the clamping element, ie when inserted into the chamber. The spread is directed with its open area towards the corner formation of the fastening element, so that when inserted the spread is pressed against the inner wall of the chamber as well as against the fastening element as such. This creates a fastening element that cannot be pulled out of the chamber again. Such non-removability also guarantees a secure and tight fit of the clamping sections within the profiles. The above-described use of invisible fastening elements, after joining two profiles in the miter area, is carried out in a watertight manner without drilling holes and screw connections in the profiles. This approach shortens assembly times and increases the quality Profile connection work for mass products such as gates, doors or windows.
Das Befestigungselement ist als Stanzbiegeteil kostengünstig herzustellen, zusätzliche Montagehilfen werden nicht benötigt.The fastening element can be manufactured inexpensively as a stamped and bent part; additional assembly aids are not required.
Die Erfindung wird anhand eines möglichen Ausführungsbeispiels näher erläutert, in dem zwei Profile zur Herstellung einer 90°Gehrungsverbindung miteinander verbunden werden.

Damit das Befestigungselement 3 jedoch allseits auf den gegenüberliegenden Seiten oder Abschnitten ein gleiches Distanzmaß in ihren Distanzabschnitten aufweist, sind die Außenwände 10, 11 der Schenkel 5, 6 mit einer Verkröpfung oder einem Rücksprung 12 versehen. Dadurch ist es möglich, dass das Distanzmaß des Distanzabschnittes 16 auch im Bereich der Verbindung der beiden Schenkel 5, 6 bestehen bleibt.However, so that the
Dadurch, dass das Befestigungselement 3 ein Stanzbiegeteil ist, sind die abgewinkelten Schenkel 5, 6 über einen Radius 13 zwischen den Distanzabschnitten 16 untereinander verbunden.Because the
Neben den Außenwänden 10, 11 wurden ferner aus dem Distanzabschnitt 16 Parallelwände 14 und 15 zu den Außenwänden 10 und 11 abgewinkelt. Durch die Parallelwand 14 und die Außenwand 11 wird dabei ein Klemmabschnitt 7 gebildet. In analoger Weise wird aus der Parallelwand 15 in Verbindung mit der Außenwand 10 ein weiterer Klemmabschnitt 8 gebildet. Diese Klemmabschnitte 7, 8 tauchen in die Kammern 4 der Profile 1, 2 bei einer Montage ein. Dabei versteht es sich, dass die Parallelwände 14 und 15 ebenfalls nicht über den Distanzabschnitt 16 hinausgehen dürfen. Die Breite der Klemmabschnitte 7, 8 wird quasi durch Klemmabschnittbreiten 17 gebildet, wobei jedoch an den offenen Seiten der Klemmabschnitte 7, 8 eine Gestaltung der Befestigungselemente 3 so sein kann, dass hier ein größeres Maß als das Maß der Distanzabschnitte 16 ausgeführt ist. Dadurch ist es möglich, dass unter einem gewissen Druck auf die Klemmabschnitte 7, 8 diese ohne Probleme in die entsprechenden Kammern 4 der Profile 1, 2 eingedrückt werden können. Um eine bessere Montage ausführen zu können, weisen die Klemmabschnitte 7, 8 an den freien Schenkelenden in Form einer Einführhilfe Abschrägungen auf. Damit die Klemmabschnitte 7, 8 innerhalb der Kammern 4 ihren passgenauen Sitz einhalten können, ist die Breite und damit das Ende der Klemmabschnitte 7, 8 durch die Klemmabschnittbreiten 17 bestimmt.In addition to the
Würde das Befestigungselement 3 in der vorbeschriebenen Art ausgeführt, so wäre ein dauerhafter kraft- und formschlüssiger Sitz innerhalb der Kammern 4 nicht ausreichend gegeben. Um einen Kraft- und Formschluss zu erreichen, befindet sich in den Distanzabschnitten 16 auf jeder Seite mindestens eine Aufspreizung 9. Die Aufspreizung 9 ist so ausgebildet, dass beim Einsetzen des Befestigungselementes 3 in die Kammer 4 dieses nur mit einem leichten Druck zu realisieren ist. Dadurch wird die Aufspreizung 9 zum Distanzabschnitt 16 gedrückt und stellt sich aber gleichzeitig mit ihrem freien Ende gegen die entsprechende Innenwandung der Kammer 4 an. Da das Befestigungselement 3 aus einem Federbandstrahl besteht, wird durch die Aufspreizung 9 eine Entfernung des Befestigungselementes 3 aus einer Kammer 4 gänzlich unterbunden, denn bei dem Versuch des Herausziehens des Befestigungselementes 3 würde sich das freie vorstehende Ende der Aufspreizung 9 in die benachbarte Wand der Kammer 4 eindrücken.If the
Durch die maßliche Abstimmung der Klemmabschnitte 7, 8 sowie der Distanzabschnitte 16 in Verbindung mit den Aufspreizungen 9 wird ein sehr präzises Befestigungselement 3 geschaffen, das ohne Werkzeuge in bestehende Kammern von den Profilen 1 und 2 nur durch äußere Krafteinwirkung eingedrückt werden muss. Dadurch entsteht in dem Gehrungsbereich bei den zueinanderstehenden Profilen 1, 2 eine dichte Ausführung untereinander, die auch eine Wasserdichtheitsgarantie mit sich bringt. Die erfindungsgemäße Verbindung von Profilen im Gehrungsbereich ist eine starre Kopplung zwischen den Profilen 1 und 2 und dem Befestigungselement 3, die nach der Montage keine Relativverschiebung untereinander zulassen.The dimensional coordination of the clamping
Die Profile 1 und 2 können aus Leichtmetallprofilen oder aus Kunststoff oder einem Hybridwerkstoff oder gar Stahl bestehen und mit den erfindungsgemäßen Gehrungsverbindungen bei Fenstern, Türen und Toren als Verschlüsse von Gebäuden und Garagen verwendet werden. Die Distanzabschnitte (16) zwischen den Klemmabschnitten (7, 8) können gleich oder unterschiedlich groß ausgebildet sein. Dabei können die Klemmabschnitte (7, 8) auch eine gleiche oder unterschiedliche Längenerstreckung aufweisen.The profiles 1 and 2 can consist of light metal profiles or plastic or a hybrid material or even steel and with the miter joints according to the invention for windows, doors and gates used as closures for buildings and garages. The distance sections (16) between the clamping sections (7, 8) can be of the same size or of different sizes. The clamping sections (7, 8) can also have the same or different lengths.
