Description

Die Erfindung betrifft ein Eckverbindungselement zur Verbindung voneinander etwa rechtwinklig gegenĆ¼berliegend angeordneten Profilelementen, welche wenigstens eine Gehrung aufweisen, umfassend zwei in einem Verbindungswinkel zueinander angeordneten Verbindungselementen, welche in wenigstens eine Hohlkammer der Profilelemente einbringbar sind.The invention relates to a corner connecting element for connecting each other approximately at right angles arranged profile elements, which have at least one miter, comprising two mutually in a connection angle connecting elements, which are introduced into at least one hollow chamber of the profile elements.

Derartige Eckverbindungselemente sind aus dem Stand der Technik vielfach bekannt und haben sich bewƤhrt.Such corner connecting elements are widely known from the prior art and have proven themselves.

So ist beispielsweise in der DE 69711149 T2 ein Eckverbindungselement beschrieben zur dichten Verbindung von zwei zusammengefĆ¼gten Profilen, deren Enden in einer dazwischenliegenden KontaktflƤche aneinander liegen, wobei die Verbindung zwischen diesen Profilen mittels eines Eckverbindungselementes hergestellt ist, das jeweils in beide dieser Profile eingreift, wobei das Eckverbindungselement ein weiches Element aufweist, und von diesem nach auƟen Ć¼bersteht, so dass es zwischen den Enden der beiden wechselseitig in der KontaktflƤche aneinander liegenden Profile zusammengedrĆ¼ckt wird, wobei dieses weiche Element in dieser FlƤche eine DiskontinuitƤt im Kapillarweg von zwischen den beiden Enden der Profile eingeschlossenem Wasser sicherstellt, wodurch das FlieƟen von Wasser durch Kapillarwirkung entlang dieses Weges verhindert werden soll.
Dabei kann das weiche Element stabfƶrmig ausgebildet und in einer Aussparung, einer Nut oder einer anderen Ɩffnung des Eckverbindungselements angeordnet sein. Das weiche Element ist dabei aus einem Kunststoffschaum gebildet.
Nachteilig bei diesem Eckverbindungselement wird gesehen, dass der Montageaufwand insbesondere des weichen Elementes hoch ist und dass insbesondere die Verbindung der im rechten Winkel einander gegenĆ¼berliegend angeordneten Profile sehr aufwendig und insbesondere im Bereich der Gehrung nicht vollumfƤnglich ohne Spaltbildung mƶglich ist. Ein weiterer Nachteil dieses Eckverbindungselementes besteht darin, dass bei fertigungsbedingten Toleranzen der Hohlkammern der gegenĆ¼berliegend angeordneten Profile beispielsweise das EinfĆ¼hren nicht mƶglich bzw. mit so viel Spiel mƶglich ist, dass insbesondere im Eckbereich der auf Gehrung einander gegenĆ¼berliegend angeordneten Profile keine exakte vorzugsweise rechtwinklige Fixierung dieser mƶglich ist, ohne das zumindest im Sichtbereich eine optisch unschƶne Spaltbildung bzw. Stufenbildung auftritt.For example, in the DE 69711149 T2 a corner connecting element for sealingly connecting two joined profiles, the ends of which lie against each other in an intermediate contact surface, the connection between these profiles is made by means of a corner connecting element which engages in both of these profiles, wherein the corner connecting element comprises a soft element, and of protruding outwards so that it is compressed between the ends of the two mutually adjacent profiles in the contact surface, this soft element in this area ensures a discontinuity in Kapillarweg trapped between the two ends of the profiles of water, whereby the flow of water should be prevented by capillary action along this path.
In this case, the soft element can be rod-shaped and arranged in a recess, a groove or another opening of the corner connecting element. The soft element is formed from a plastic foam.
A disadvantage of this corner connecting element is seen that the assembly cost, in particular of the soft element is high and that in particular the connection of the oppositely arranged at right angles profiles very complex and especially in the miter is not fully possible without gap formation. Another disadvantage of this Eckverbindungselementes is that in production-related tolerances of the hollow chambers of the oppositely arranged profiles, for example the insertion is not possible or with so much play is possible that especially in the corner of the miter oppositely arranged profiles no exact preferably rectangular fixing this is possible without at least in the field of vision, an optically unsightly gap formation or step formation occurs.

Aus der EP 1054133 ist ein weiteres Eckverbindungselement bekannt.
Dieses Eckverbindungselement fĆ¼r die Rahmeneckverbindung fĆ¼r zumindest zwei Rahmenhohlprofile weist zwei oder mehr Verbindungsschenkel auf, wobei diese Verbindungsschenkel in die auf Gehrung geschnittenen Rahmenhohlprofile eingreifen, wobei die Verbindungsschenkel jeweils ein oder mehrere FederblƤtter aufweisen, welche als Widerhaken gegen die InnenflƤchen der Rahmenhohlprofile anliegen.
Diese FederblƤtter sind vorzugsweise aus Metall beispielsweise aus Stahl hergestellt und sind in einer Nut der Verbindungselemente etwas rechtwinklig zur Hohlkammer der Rahmenprofile angeordnet. Dabei sind die FederblƤtter so ausgebildet, dass sie um ein vorgegebenes MaƟ aus den Federblattaufnahmen hervorragen.
Bei der Montage der Rahmenhohlprofile wird dieses Eckverbindungselement so in die Hohlkammer eingeschoben, dass sich das Federblatt aufgrund seiner Ausdehnung an der Innenseite der Hohlkammer verbiegt. Da die Rahmenprofile vorzugsweise aus Kunststoff oder Weichmetall wie zum Beispiel Alu gefertigt sind, kann sich somit das Federblatt, welches aus einem wesentlichen hƤrteren Werkstoff hergestellt ist, in die InnenflƤche der Rahmenhohlprofile einkrallen und so nicht mehr herausgezogen werden.
Die FederblƤtter werden dabei in senkrecht zur Einschieberichtung angeordnete Nuten in die Verbindungselemente eingebracht und kƶnnen sich somit Ć¼ber ihre gesamte FlƤche an der InnenflƤche der Rahmenhohlprofile einkrallen.
Nachteilig bei diesem Eckverbindungselement ist, dass die gewƤhlte Geometrie des Verbindungselementes nicht auf die Spannungssituation beim Gehrungsschnitt abgestimmt ist und dass so beim Fixieren der Rahmenprofile insbesondere im Sichtbereich eine optisch unschƶne Spaltbildung bzw. Stufenbildung entsteht.
Ein weiterer Nachteil des Eckverbindungselementes besteht darin, dass die einander etwa rechtwinklig gegenĆ¼berliegenden Rahmenhohlprofile im Bereich der Gehrung stufenartig nebeneinander bzw. Ć¼bereinander liegen und nicht genau gegenĆ¼berliegend.
Ebenfalls nachteilig bei dem Eckverbindungselement wird gesehen, dass bei fertigungsbedingten Toleranzen in der Herstellung des Eckverbindungselementes und / oder der Rahmenhohlprofile es denkbar ist, dass das Eckverbindungselement nicht, nur sehr schwer oder mit sehr viel Spiel in die Hohlkammern der Rahmenhohlprofile einbringbar ist und so die RĆ¼ckhaltekraft der FederblƤtter nicht oder nicht richtig wirken kann.
Weiterhin nachteilig bei diesem Eckverbindungselement ist, dass es beim Einschieben in die Hohlkammern der Rahmenhohlprofile zu Deformierungen dieser Profile im Sichtbereich kommen kann bzw. zu mƶglicherweise SchƤdigungen durch die in das Material der Rahmenhohlprofile eingreifenden FederblƤtter.From the EP 1054133 Another corner connector is known.
This Eckverbindungselement for the frame corner joint for at least two hollow frame profiles has two or more connecting leg, said connecting legs engage in the mitered hollow frame profiles, wherein the connecting legs each have one or more spring leaves which abut as barbs against the inner surfaces of the hollow frame profiles.
These spring leaves are preferably made of metal, for example made of steel and are arranged in a groove of the connecting elements somewhat perpendicular to the hollow chamber of the frame profiles. In this case, the spring leaves are formed so that they protrude by a predetermined amount from the Federblattaufnahmen.
When mounting the frame hollow profiles, this corner connecting element is inserted into the hollow chamber, that the spring leaf bends due to its expansion on the inside of the hollow chamber. Since the frame profiles are preferably made of plastic or soft metal such as aluminum, thus, the spring leaf, which is made of a substantially harder material, in the inner surface of the hollow frame profiles einkrallen and so not be pulled out.
The spring leaves are thereby introduced in perpendicular to the insertion direction grooves in the connecting elements and can thus engage over its entire surface on the inner surface of the hollow frame profiles.
A disadvantage of this corner connecting element is that the selected geometry of the connecting element is not adapted to the voltage situation during miter cutting and that thus creates a visually unsightly gap formation or step formation when fixing the frame profiles, especially in the field of vision.
Another disadvantage of the Eckverbindungselementes is that the approximately mutually perpendicular frame hollow sections in the miter area are stepwise next to each other or one above the other and not exactly opposite each other.
Another disadvantage of the corner connecting element is seen that in production-related tolerances in the production of the corner connecting element and / or the hollow frame profiles, it is conceivable that the corner connecting element not, very difficult or with a lot of game in the hollow chambers of the frame hollow profiles can be introduced and so the retention force of the spring leaves can not work properly or not.
Another disadvantage of this corner connecting element is that it can come to the visible range during insertion into the hollow chambers of the frame hollow profiles to deformations of these profiles or to possibly damage by engaging in the material of the hollow frame profiles spring leaves.

Dabei steht jedoch nicht der Schenkel, sondern die daran angeordnete Rasthaken mit der Wand der Hohlkammer des Profilelements in Wirkverbindung. Der Schenkel ist zwar parallel in LƤngsrichtung des Profilelements angeordnet, jedoch der Rasthaken ist senkrecht zur ProfillƤngsrichtung angeordnet, da sonst das Eckverbindungselement nicht in der Hohlkammer des Profilelementes fixiert werden kƶnnte.The EP 2568104 A1 discloses a corner connecting element for connecting each other approximately at right angles profiles having at least one miter, comprising four mutually arranged spring elements, which are introduced into at least one hollow chamber of the profile elements, wherein of the spring elements only the part of the wall of the hollow chamber of the profile element is arranged spaced and wherein a latching element is in operative connection with the wall of the profile. However, it is not the leg, but the latching hook arranged thereon with the wall of the hollow chamber of the profile element in operative connection. Although the leg is arranged parallel in the longitudinal direction of the profile element, but the latching hook is arranged perpendicular to the profile longitudinal direction, otherwise the corner connecting element could not be fixed in the hollow chamber of the profile element.

Hier setzt die Erfindung ein, die sich die Aufgabe gestellt hat, die Nachteile des bekannten Standes der Technik zu Ć¼berwinden und ein Eckverbindungselement aufzuzeigen, welches wirtschaftlich und kostengĆ¼nstig herstellbar ist, welches insbesondere im Bereich der Gehrung voneinander gegenĆ¼berliegend anzuordnenden Profile einfach montierbar ist und fĆ¼r derartige Profilelemente zu einer spaltfreien bzw. stufenfreien Verbindung im Eckbereich sorgt.This is where the invention, which has set itself the task of overcoming the disadvantages of the known prior art and to show a corner joint, which is economical and inexpensive to produce, which in particular in the miter of opposing profiles to be arranged easily mounted and for such Profile elements ensures a gap-free or stepless connection in the corner.

Es konnte Ć¼berraschend festgestellt werden, dass ein Eckverbindungselement zur Verbindung voneinander etwa rechtwinklig gegenĆ¼berliegend angeordneten Profilelementen, welche wenigstens eine Gehrung aufweisen, umfassend zwei in einem Verbindungswinkel zueinander angeordneten Verbindungselementen, welche in wenigstens eine Hohlkammer der Profilelemente einbringbar sind, sich dadurch auszeichnet, dass wenigstens eine Seite des Verbindungselementes vollstƤndig beabstandet von einer Wand der Hohlkammer des Profilelementes, mit dieser Ć¼ber wenigstens ein Federelement in Wirkverbindung stehend, angeordnet ist. Das erfindungsgemƤƟe Eckverbindungselement zeichnet sich dadurch aus, dass durch deren vorteilhafte Ausgestaltung ein Ausgleich der herstellungsbedingten Toleranzen insbesondere der Profile sowohl in waagerechter als auch in senkrechter Richtung mƶglich ist und dass dadurch eine wesentliche Verbesserung der QualitƤt sowohl der mechanischen Eigenschaften als auch der optischen Eigenschaften in der Gehrung der verbundenen Profilelemente realisiert ist. Ein weiterer Vorteil des erfindungsgemƤƟen Eckverbindungselementes besteht darin, dass mit deren Hilfe eine schnelle, einfache und kostengĆ¼nstige Montage von Rahmen fĆ¼r TĆ¼ren, Fenster und dergleichen mƶglich ist.It has surprisingly been found that a corner connecting element for connecting each other approximately at right angles arranged opposite profile elements, which have at least one miter, comprising two in a connection angle mutually arranged connecting elements, which are introduced into at least one hollow chamber of the profile elements, is characterized in that at least one side of the connecting element is completely spaced from a wall of the hollow chamber of the profile element, with this at least one spring element operatively connected, is arranged. The corner connecting element according to the invention is characterized in that by the advantageous embodiment of a compensation of manufacturing tolerances of the profiles in both horizontal and vertical direction is possible and thereby a significant improvement in the quality of both the mechanical properties and the optical properties in the Miter of the connected profile elements is realized. Another advantage of the corner connecting element according to the invention is that with the help of a quick, simple and inexpensive installation of frames for doors, windows and the like is possible.

Das erfindungsgemƤƟe Eckverbindungselement ist vorteilhafterweise so ausgebildet, dass das Federelement etwa parallel zur LƤngsrichtung des Profilelements am Verbindungselement angeordnet ist. Hierdurch ist es mƶglich, dass bei bestimmungsgemƤƟem Einbringen des Eckverbindungselementes in etwa rechtwinklig gegenĆ¼berliegend angeordnete Profilelemente keine mechanischen Belastungen bzw. Deformationen im Bereich der Gehrung entstehen und somit keine Stufenbildung bzw. Spaltbildung in diesem optisch und mechanisch sensiblen Bereich zu verzeichnen sind.The corner connecting element according to the invention is advantageously designed so that the spring element is arranged approximately parallel to the longitudinal direction of the profile element on the connecting element. This makes it possible that when properly introduced the corner connecting element approximately at right angles oppositely arranged profile elements no mechanical loads or deformations in the miter arise and thus no step formation or gap formation are recorded in this optically and mechanically sensitive area.

Weiterhin zeichnet sich das erfindungsgemƤƟe Eckverbindungselement dadurch aus, dass das Federelement wenigstens einen Federschenkel aufweist, wobei der Federschenkel vorteilhafterweise in etwa einem spitzen Winkel zur Seite des Verbindungselements angeordnet ist. Hierdurch ist es vorteilhafterweise mƶglich, fertigungsbedingte Toleranzen insbesondere der Hohlkammer der Profilelemente auszugleichen, da der Federschenkel beim Einbringen in die Hohlkammer des Profilelementes durch die Wand der Hohlkammer elastisch zu einer Seite des Verbindungselementes nachgibt und so entsprechende Toleranzschwankungen optimal ausgleicht.Furthermore, the corner connecting element according to the invention is characterized in that the spring element has at least one spring leg, wherein the spring leg is advantageously arranged approximately at an acute angle to the side of the connecting element. As a result, it is advantageously possible to compensate for production-related tolerances, in particular the hollow chamber of the profile elements, since the spring leg yields elastically to one side of the connecting element through the wall of the hollow chamber when introduced into the hollow chamber of the profile element and thus optimally compensates for corresponding tolerance variations.

Es hat sich weiterhin als vorteilhaft herausgestellt, dass das erfindungsgemƤƟe Eckverbindungselement an wenigstens einem Federschenkel des Federelements wenigstens ein zweites Distanzelement aufweist. Dieses zweite Distanzelement ist vorteilhafterweise im Querschnitt etwa prismatisch, rund, halbrund, oval, dreieckig, mehreckig und dergleichen ausgebildet und fĆ¼hrt dazu, dass das in die Hohlkammer der Profilelemente eingefĆ¼hrte Eckverbindungselement immer fest in der Hohlkammer des Profilelementes angeordnet ist, ohne dass zusƤtzliche mechanische Befestigungen wie bspw. Schrauben bzw. stoffschlĆ¼ssige Verbindungen Ć¼ber an sich bekannte Klebstoffsysteme erforderlich sind und dass trotzdem keine Stufen und/oder Spalten zwischen den einander rechtwinklig gegenĆ¼berliegend angeordneten Profilelementen entstehen.It has also proven to be advantageous that the corner connecting element according to the invention has at least one second spacer element on at least one spring leg of the spring element. This second spacer element is advantageously approximately in cross-section prismatic, round, semicircular, oval, triangular, polygonal and the like formed and causes the inserted into the hollow chamber of the profile elements corner connecting element is always fixedly disposed in the hollow chamber of the profile element, without additional mechanical fasteners such as screws or cohesive connections are required on per se known adhesive systems and that nevertheless no steps and / or gaps between the mutually perpendicular profile elements arranged opposite each other arise.

In einer weiteren vorteilhaften Ausgestaltung des erfindungsgemƤƟen Eckverbindungselementes ist an wenigstens einer Seite des Verbindungselementes wenigstens ein Auflageelement angeordnet. Dieses Auflageelement, welches bspw. an der dem Federelement gegenĆ¼berliegenden Seite angeordnet ist, fĆ¼hrt insbesondere beim Einschieben des Eckverbindungselementes in die Hohlkammer der Profilelemente zu einem besseren Gleiten und zu einer exakten Positionierung des erfindungsgemƤƟen Eckverbindungselementes in der Hohlkammer des Profilelementes.In a further advantageous embodiment of the corner connecting element according to the invention at least one support element is arranged on at least one side of the connecting element. This support element, which is arranged, for example, on the opposite side of the spring element, leads in particular during insertion of the Eckverbindungselementes in the hollow chamber of the profile elements to a better sliding and exact positioning of the corner connecting element according to the invention in the hollow chamber of the profile element.

Es hat sich ebenfalls als vorteilhaft herausgestellt, dass an wenigstens einer Seite des Verbindungselementes wenigstens ein, etwa parallel zum Federelement angeordnetes, erstes Distanzelement angeordnet ist. Dieses erste Distanzelement, welches beispielsweise einstĆ¼ckig am Verbindungselement angeordnet ist und im Querschnitt etwa prismatisch, rund, halbrund, oval, dreieckig, mehreckig und dergleichen ausgebildet ist, bewirkt beim erfindungsgemƤƟen Eckverbindungselement, dass sich dieses in der Hohlkammer des Profilelementes entsprechend ausrichtet und insbesondere fertigungsbedingte Toleranzen der Profilelemente in waagerechte sowie senkrechte Richtung ausgeglichen werden.It has also been found to be advantageous that at least one, arranged approximately parallel to the spring element, first spacer element is arranged on at least one side of the connecting element. This first spacer element, which is arranged for example in one piece on the connecting element and approximately prismatic in cross section, round, half-round, oval, triangular, polygonal and the like, causes the corner connecting element according to the invention, that this aligns in the hollow chamber of the profile element and in particular production-related tolerances of the profile elements in horizontal and vertical directions are compensated.

Es hat sich weiterhin als vorteilhaft herausgestellt bei dem erfindungsgemƤƟen Eckverbindungselement, dass das Federelement und / oder das Distanzelement und / oder das Auflageelement einstĆ¼ckig am Verbindungselement angeordnet ist. Dies fĆ¼hrt neben einer wirtschaftlichen und kostengĆ¼nstigen Herstellung des erfindungsgemƤƟen Eckverbindungselementes zu einer einfachen Montierbarkeit und durch die Dimensionierung insbesondere der Geometrie des Federelementes sowie des Distanzelementes dazu, dass fertigungsbedingte Toleranzen der Profilelemente einfach ausgeglichen werden kƶnnen.It has also proven to be advantageous in the corner connecting element according to the invention, that the spring element and / or the spacer element and / or the support element is arranged integrally on the connecting element. This leads to an economical and cost-effective production of Eckverbindungselementes invention to a simple mountability and by sizing in particular the geometry of the spring element and the spacer to the fact that manufacturing tolerances of the profile elements can be easily compensated.

Dabei hat es sich ebenfalls als vorteilhaft herausgestellt, dass bei dem erfindungsgemƤƟen Eckverbindungselement das Federelement und / oder das Distanzelement und / oder das Auflageelement kraft- und / oder formschlĆ¼ssig am Verbindungselement angeordnet ist. Durch diese vorteilhafte Ausgestaltung ist es mƶglich, unterschiedliche Werkstoffe fĆ¼r die einzelnen Elemente des Verbindungselementes zu verwenden und diese den entsprechenden Anforderungen der zu verbindenden Profilelemente so anzupassen, dass das erfindungsgemƤƟe Eckverbindungselement zu einer optisch ansprechenden und mechanisch sicheren Verbindung der Profilelemente beitrƤgt. Ein weiterer Vorteil besteht darin, dass bei einem spƤteren RĆ¼ckbau der aus den Profilelementen hergestellten Rahmen ein werkstoffgerechtes Recycling der einzelnen Elemente problemlos mƶglich ist.It has also been found to be advantageous that in the corner connecting element according to the invention, the spring element and / or the spacer element and / or the support element is non-positively and / or positively arranged on the connecting element. This advantageous embodiment makes it possible to use different materials for the individual elements of the connecting element and to adapt them to the corresponding requirements of the profile elements to be connected so that the corner connecting element according to the invention contributes to a visually appealing and mechanically secure connection of the profile elements. Another advantage is that in a later dismantling of the frame produced from the profile elements a material-appropriate recycling of the individual elements is easily possible.

Es hat sich auch weiterhin als vorteilhaft beim erfindungsgemƤƟen Eckverbindungselement herausgestellt, dass wenigstens eine Wand der Hohlkammer des Profilelementes wenigstens ein drittes Distanzelement aufweist. Bei dieser vorteilhaften Ausgestaltung ist eine kostengĆ¼nstige und wirtschaftliche Einbringung des dritten Distanzelementes, welches dabei bspw. an der dem Federelement des Verbindungselements gegenĆ¼berliegende Wand der Hohlkammer des Profilelementes angeordnet ist, realisierbar, so dass verschieden dimensionierte Federelemente des erfindungsgemƤƟen Eckverbindungselementes fĆ¼r die Verbindung der Profilelemente einsetzbar sind.It has also been found to be advantageous in the corner connecting element according to the invention that at least one wall of the hollow chamber of the profile element has at least one third spacer element. In this advantageous embodiment, a cost-effective and economical introduction of the third spacer element, which is arranged, for example. At the spring element of the connecting element opposite wall of the hollow chamber of the profile element, feasible, so that different sized spring elements of the corner connecting element according to the invention for the connection of the profile elements can be used ,

Dabei hat sich als besonders vorteilhaft herausgestellt, dass bei dem erfindungsgemƤƟen Eckverbindungselement das erste Distanzelement und / oder das zweite Distanzelement und / oder das dritte Distanzelement im Querschnitt etwa prismatisch, rund, halbrund, oval, dreieckig, mehreckig und dergleichen ausgebildet ist. Hierdurch ist eine einfache Montage des erfindungsgemƤƟen Eckverbindungselements in den Hohlkammern der Profilelemente mƶglich und das Eckverbindungselement sitzt straff und fest ohne zusƤtzliche Befestigungsmittel in der Hohlkammer des Profilelementes.
Ein weiterer wesentlicher Vorteil des erfindungsgemƤƟen Eckverbindungselementes ist, dass das Federelement und / oder das Auflageelement und / oder das Distanzelement in etwa die gleiche LƤngenausdehnung aufweist wie das Verbindungselement. Hierdurch ist eine kostengĆ¼nstige und wirtschaftliche Herstellung des erfindungsgemƤƟen Eckverbindungselementes mƶglich. Weiterhin kann insbesondere durch die LƤnge der Verbindungselemente des erfindungsgemƤƟen Eckverbindungselementes eine optisch ansprechende und mechanisch sichere Verbindung der mit einer Gehrung versehenen Profilelemente realisiert werden, egal wie lang, breit bzw. dick diese Profilelemente ausgestaltet sind. Weiterhin vorteilhaft weist das erfindungsgemƤƟe Eckverbindungselement wenigstens eine im Verbindungselement angeordnete Hohlkammer auf. Diese fĆ¼hrt neben der Materialersparnis und den damit verbundenen, gĆ¼nstigen Herstellungskosten auch zu einer Gewichtsreduzierung des erfindungsgemƤƟen Eckverbindungselementes, ohne dass die zu realisierende Verbindung der Profilelemente beeintrƤchtigt ist.
Dabei hat es sich weiterhin als vorteilhaft herausgestellt, dass die Hohlkammer in etwa parallel zum Federelement des Verbindungselementes angeordnet ist, was vorteilhafterweise zu einer kostengĆ¼nstigen Herstellung des erfindungsgemƤƟen Eckverbindungselementes fĆ¼hrt. Der erste Federschenkel des Federelementes ist etwa parallel zur einen Seite des Verbindungselementes Ć¼ber wenigstens einen zweiten Federschenkel beabstandet angeordnet. Durch diese AusfĆ¼hrungsform lƤsst sich das erfindungsgemƤƟe Eckverbindungselement so in die Hohlkammern der Profilelemente einbringen, dass insbesondere im spƤteren Sichtbereich der aus den Profilelementen hergestellten Rahmen, TĆ¼ren und dergleichen keine Abzeichnungen bzw. Verformungen erkennbar sind und dass insbesondere im Bereich der auf Gehrung einander gegenĆ¼berliegend angeordneten Profilelemente ein fester mechanischer Sitz und keine optisch sichtbare Stufe realisiert ist.It has been found to be particularly advantageous that in the corner connecting element according to the invention, the first spacer element and / or the second spacer element and / or the third spacer element in cross-section approximately prismatic, round, semicircular, oval, triangular, polygonal and the like is formed. As a result, a simple assembly of the corner connecting element according to the invention in the hollow chambers of the profile elements is possible and the corner connecting element sits tight and firm without additional fastening means in the hollow chamber of the profile element.
Another significant advantage of the corner connecting element according to the invention is that the spring element and / or the support element and / or the spacer element has approximately the same length extension as the connecting element. As a result, a cost-effective and economical production of the corner connecting element according to the invention is possible. Furthermore, in particular by the length of the connecting elements of the corner connecting element according to the invention, a visually appealing and mechanically secure connection of the mitered profiled elements can be realized, no matter how long, wide or thick these profile elements are configured. Further advantageously, the corner connecting element according to the invention has at least one hollow chamber arranged in the connecting element. This results in addition to the material savings and the associated, low production costs and to a weight reduction of the corner connecting element according to the invention, without the realizable connection of the profile elements is impaired.
It has also been found to be advantageous that the hollow chamber is arranged approximately parallel to the spring element of the connecting element, which advantageously leads to a cost-effective production of the corner connecting element according to the invention. The first spring leg of the spring element is spaced approximately parallel to one side of the connecting element via at least one second spring leg. By means of this embodiment, the corner connecting element according to the invention can be introduced into the hollow chambers of the profile elements such that no marks or deformations can be recognized, especially in the later field of vision of the frames, doors and the like produced by the profile elements and that in particular in the area of the profiled elements opposite each other a solid mechanical seat and no optically visible stage is realized.

Dabei sind der erste und der zweite Federschenkel des Federelementes einstĆ¼ckig miteinander verbunden und ebenfalls einstĆ¼ckig am Verbindungselement angeordnet. Der erste Federschenkel des Federelementes ist dabei etwa parallel beabstandet zum Verbindungselement angeordnet, wƤhrend der zweite Federschenkel rechtwinklig am Verbindungselement angeordnet ist.
In einer weiteren vorteilhaften Ausgestaltung ist der zweite Federschenkel des Federelementes mittig in LƤngsrichtung des Verbindungselementes an diesem angeordnet. Es liegt jedoch auch im Rahmen der Erfindung, dass der zweite Federschenkel des Federelementes auƟermittig parallel zur einen Seite des Verbindungselementes an diesem angeordnet ist.In this case, the first and second spring legs of the spring element are integrally connected to each other and also arranged integrally on the connecting element. The first spring leg of the spring element is arranged approximately parallel spaced from the connecting element, while the second spring leg is arranged at right angles to the connecting element.
In a further advantageous embodiment, the second spring leg of the spring element is arranged centrally in the longitudinal direction of the connecting element at this. However, it is also within the scope of the invention that the second spring leg of the spring element is arranged eccentrically parallel to one side of the connecting element at this.

Ebenfalls vorteilhaft bei dem erfindungsgemƤƟen Eckverbindungselement ist, dass das eine Verbindungselement einstĆ¼ckig mit dem anderen Verbindungselement verbunden ist. Hierdurch ist eine kostengĆ¼nstige Herstellung sowie eine ausreichende mechanische Festigkeit der Verbindungselemente des erfindungsgemƤƟen Eckverbindungselementes realisierbar.Also advantageous in the corner connecting element according to the invention is that the one connecting element is integrally connected to the other connecting element. As a result, a cost-effective production and a sufficient mechanical strength of the connecting elements of the corner connecting element according to the invention can be realized.

Es hat sich jedoch auch weiterhin als vorteilhaft herausgestellt, dass das eine Verbindungselement form- und / oder kraftschlĆ¼ssig mit dem anderen Verbindungselement verbunden ist. Hierdurch ist es vorteilhafterweise mƶglich, die Verbindungselemente beispielsweise aus unterschiedlichen Werkstoffen herzustellen und erst fĆ¼r die Herstellung der Verbindung zwischen den Profilelementen kostengĆ¼nstig ineinanderzufĆ¼gen und bei RĆ¼ckbau wieder zu recyceln.However, it has also proven to be advantageous that the one connecting element is positively and / or non-positively connected to the other connecting element. As a result, it is advantageously possible to produce the connecting elements, for example, of different materials and economically interlock with each other only for the preparation of the connection between the profile elements and to recycle again when dismantled.

Dabei kann es sich ebenfalls als vorteilhaft herausstellen, dass das Verbindungselement aus einem metallischen Werkstoff hergestellt ist. Dies fĆ¼hrt zu einer insbesondere mechanischen Stabilisierung der zu verbindenden Profilelemente.It may also prove to be advantageous that the connecting element is made of a metallic material. This leads to a particular mechanical stabilization of the profile elements to be connected.

Weiterhin hat es sich ebenfalls als vorteilhaft herausgestellt, dass das Verbindungselement aus einem polymeren Werkstoff hergestellt ist. Hierdurch ist einerseits eine kostengĆ¼nstige und einfache Herstellung beispielsweise im an sich bekannten SpritzgieƟverfahren mƶglich, wƤhrend andererseits das erfindungsgemƤƟe Eckverbindungselement neben dem geringen Gewicht beispielsweise beim Einsatz der Profilelemente zur Herstellung von Rahmen fĆ¼r Fenster, TĆ¼ren, KĆ¼hl- bzw. GefriergerƤte immer korrosionsbestƤndig ausgebildet ist.Furthermore, it has also been found to be advantageous that the connecting element is made of a polymeric material. In this way, on the one hand, a cost-effective and simple production, for example in the known injection molding possible, while on the other hand corner joint according to the invention is always resistant to corrosion in addition to the low weight, for example, when using the profile elements for the production of frames for windows, doors, refrigerators and freezers.

Die Profilelemente 30, 40 weisen jeweils eine in ProfillƤngsrichtung ausgebildete Hohlkammer 31, 41 auf. Die Hohlkammer 31 des Profilelements 30 ist dabei von den WƤnden 32, 33, 34, 35 umgeben, wƤhrend die Hohlkammer 41 des Profilelements 40 durch die WƤnde 42, 43, 44, 45 umschlossen ist.
Das erfindungsgemƤƟe Eckverbindungselement 1 ist Ć¼ber das in dieser Figur nicht erkennbare Verbindungselement 10 in der Hohlkammer 31 des Profilelements 30 angeordnet. Die Profilelemente 30, 40 weisen an ihren einem freien Ende eine Gehrung 9 von etwa 45Ā° auf, Ć¼ber die sie Ć¼ber das erfindungsgemƤƟe Eckverbindungselement 1 aneinander angefĆ¼gt und miteinander verbunden werden.
Dabei wird das Verbindungselement 20 des Eckverbindungselementes 1 in die Hohlkammer 41 des Profilelementes 40 eingeschoben und das Profilelement 40 soweit lƤngs Ć¼ber das Verbindungselement 20 bewegt, bis die Gehrung 9 des Profilelementes 40 direkt neben der Gehrung 9 des Profilelementes 30 angeordnet ist.
Durch das erfindungsgemƤƟe Eckverbindungselement 1 ist es somit mƶglich, die Profilelemente 30,40 an der Gehrung 9 so miteinander zu verbinden, dass kein Spalt zwischen den Gehrungen 9 sichtbar ist und das insbesondere keine Stufenbildung durch versetzt voneinander angeordnete Gehrungen 9 der Profilelemente 30, 40 auftritt.
Durch die vorteilhafte Ausgestaltung des erfindungsgemƤƟen Eckverbindungselementes 1 ist es somit mƶglich, dass das Verbindungselement 10, 20 des Eckverbindungselementes 1 einfach und schnell in Verschieberichtung A in die Hohlkammer 31, 41 des Profilelementes 30, 40 einfĆ¼hrbar und in dieser kraftschlĆ¼ssig fixierbar ist.The profile elements 30, 40 each have a hollow profile 31, 41 formed in the longitudinal direction of the profile.
