Definitions
- This invention relates to joints of mitered portions of two abutting profiles used for windows, doors or gates for building and garage door closures, where the profiles have at least one internal chamber used for fastener insertion.
- FR 2 225 605 discloses a door frame which consists of three main profiles and is mitred 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.
- On the outer edges of the L-shaped clip are projections that have a bent overhanging area.
- An angled corner connector for hollow profiles is the DE 94 16 529 U1 again.
- 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.
- the versions of the miter joints are designed very complex and especially in the DE 36 04 006 A1 not applicable to profiles that are closed on all sides, such as those used today to build windows, doors and gates.
- the execution of FR 2 225 605 can be used with frames, but the definition within the profiles is insufficient, so that additional fasteners or aids have to be used.
- 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, for example in the form of screws or adhesives, must be used because such use is very time-consuming and increases the installation costs. Furthermore, at the same time, in addition to being inexpensive to manufacture, such a miter joint should also be essentially watertight, so that no moisture can get into the interior of the profile from outside the miter joint.
- a fastening element for connecting a miter area of two abutting profiles, which consists of two stable sections at an angle of 90° to one another.
- 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 in the chambers of the profiles, they are no longer visible from 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 walls of the chamber on all sides, so that displacement due to a snug fit is impossible.
- 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 adjustment to the inner walls of the chamber without play as a snug fit.
- the fastening elements have resilient sections. This is achieved in that the fastening element is made from austenitic chromium-nickel steel. Such steel is not rusting and has large spring forces. Nevertheless, such a steel is easy to form, 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. Furthermore, 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 consists essentially of two opposing U-shaped sections consisting of a thin sheet metal, which are connected to one another on one side in their back by an essentially straight spacer section.
- the design of the longitudinal extent 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 produced inexpensively as a stamped and bent part, additional assembly aids are not required.
- FIG. 1 two profiles 1 and 2 are shown, which can be positively and non-positively connected in a miter area using fastening elements 3 without additional tools, so that a watertight and resilient connection is created in this miter area after assembly.
- the fastening elements 3 are used in two separate, adjacent chambers 4 of the profiles 1, 2.
- the figures 2 and 3 show such a usable fastener 3 in different views.
- the fastening element 3 is an angular component whose basic elements 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 means of a spot weld.
- the fastening element 3 has the same spacing in its spacing sections on all sides or sections on opposite sides, 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 of the spacer section 16 to remain the same 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 spacer sections 16 .
- a 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 dip into the chambers 4 of the profiles 1, 2 in one assembly. It goes without saying that the parallel walls 14 and 15 must not go beyond the spacer section 16 either.
- the width of the clamping sections 7, 8 is quasi formed by clamping section widths 17, but the design of the fastening elements 3 on the open sides of the clamping sections 7, 8 can be such that a larger dimension than the dimension of the spacer sections 16 is implemented here.
- the clamping sections 7, 8 have bevels on the free leg ends in the form of an insertion aid.
- the width and thus the end of the clamping sections 7 , 8 is determined by the clamping section widths 17 so that the clamping sections 7 , 8 can maintain their precise fit within the chambers 4 .
- the fastening element 3 were to be designed in the manner described above, a permanent, non-positive and positive fit within the chambers 4 would not be adequate.
- the spread 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 slight pressure. As a result, the spread 9 is pressed toward the spacer section 16 and, at the same time, its free end is positioned against the corresponding inner wall of the chamber 4 .
- the fastening element 3 consists of a spring ribbon jet
- the spread 9 completely prevents the fastening element 3 from being removed from a chamber 4, because if the fastening element 3 were to be pulled out, the free protruding end of the spread 9 would penetrate into the adjacent wall of the chamber 4 push in.
- the profiles 1 and 2 can consist of light metal profiles or plastic or a hybrid material or even steel and can be used with the miter joints according to the invention for windows, doors and gates as closures of buildings and garages.
- the spacer sections (16) between the clamping sections (7, 8) can be of the same or 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 Gebäudeund 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, for example in the form of screws or adhesives, must be used because such use is very time-consuming and increases the installation costs. Furthermore, at the same time, in addition to being inexpensive to manufacture, such a miter joint should also be essentially watertight, so that no moisture can get into the interior of the profile 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 dependent claims 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.To connect two profiles, which are preferably designed as light metal profiles and have at least one self-contained chamber inside, 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. In the case of certain profile designs that are exposed to heavy movement loads, for example, it makes sense to have two chambers 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 in the chambers of the profiles, they are no longer visible from 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 walls of the chamber on all sides, so that displacement due to a snug fit is impossible.
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 adjustment to the inner walls of the chamber without play as a snug fit. In order to be able to compensate for existing tolerances both in the profiles and in the fastening elements, the fastening elements have resilient sections. This is achieved in that the fastening element is made from austenitic chromium-nickel steel. Such steel is not rusting and has large spring forces. Nevertheless, such a steel is easy to form, 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. Furthermore, 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 consists essentially of two opposing U-shaped sections consisting of a thin sheet metal, which are connected to one another on one side in their back by an essentially straight spacer section. The design of the longitudinal extent of the clamping sections depends on the size of the profiles to be connected and the loads. The width of the clamping sections, on the other hand, 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 mit ihrem offenen Bereich ist zu der Eckausbildung des Befestigungselementes gerichtet, so 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-detachable and overall tight fit of the clamping sections within the chambers, there is at least one outwardly directed spread of the existing material in each of the clamping sections. The at least one spread is placed in the back part, ie in the spacer section. As a result, the spread is slightly compressed when the clamping element is assembled, ie when it is inserted into the chamber. The spread with its open area is directed towards the corner formation of the fastener, so on insertion the spread is pressed against the inner wall of the chamber as well as against the fastener itself. This creates a fastener that cannot be pulled out of the chamber again. Such non-removability also guarantees at the same time a secure and tight fit of the clamping sections within the profiles. The above-described use of non-visible fasteners, after joining two profiles in the miter area, is carried out in a watertight manner without drilling or screw connections in the profiles. This procedure shortens the assembly times and increases the quality of the profile connection work for mass-produced products such as gates, doors or windows.
Das Befestigungselement ist als Stanzbiegeteil kostengünstig herzustellen, zusätzliche Montagehilfen werden nicht benötigt.The fastening element can be produced 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 Außenwänden 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 seinem 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.Due to 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 can be used with the miter joints according to the invention for windows, doors and gates as closures of buildings and garages. The spacer sections (16) between the clamping sections (7, 8) can be of the same or different sizes. The clamping sections (7, 8) can also have the same or different lengths.
