Description

Die Erfindung betrifft einen Rahmen zur Halterung eines flachen Körpers mit vieleckigem, insbesondere rechteckigem Umriss, wobei der Rahmen aus im wesentlichen geraden Profilholmen besteht, die an ihren Stirnseiten miteinander verbunden sind.The invention relates to a frame for holding a flat body with polygonal, in particular rectangular outline, wherein the frame of substantially straight profile spars exists, which are connected to each other at their ends.

Derartige Rahmen sind seit langem bekannt und werden beispielsweise zur Halterung von elektrischen bzw. elektronischen Geräten eingesetzt. Insbesondere flache Anzeigeelemente wie LCD-Displays oder Plasmadisplays werden in einem Gehäuse angeordnet, das einen Rahmen und eine Rückwand aufweist. Hierbei werden entweder geeignete Kunststoffe oder bevorzugt Teile aus leichtem Metall verwendet. Bei der Herstellung des Rahmens wurden die Profilholme bislang direkt oder über Eckwinkelverbinder miteinander verschweißt, verklebt oder verpresst, um eine sichere Verbindung herzustellen. Dies erfordert einen relativ hohen Arbeits- und Kostenaufwand bei der Montage, und eine Demontage ist ohne Zerstörung des Rahmens nur schwer oder überhaupt nicht möglich.Such frames have long been known and are used for example for mounting used electrical or electronic devices. In particular, flat display elements As LCD displays or plasma displays are arranged in a housing, the a frame and a rear wall. Here are either suitable plastics or preferably used parts of light metal. In the production of the frame were the profile spars so far welded directly or via corner angle connector, glued or pressed to make a secure connection. This requires a relatively high labor and cost of assembly, and disassembly is difficult or impossible to do without destroying the frame.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Rahmen zur Halterung eines flachen Körpers zu schaffen, der mit einfachen Mitteln montierbar und demontierbar ist und der flexibel an die Größe und Form des Körpers angepaßt werden kann, wobei keine Einschränkungen hinsichtlich der Ästhetik auftreten sollen.The present invention is therefore based on the object, a frame for mounting to create a flat body that can be assembled and disassembled with simple means is flexible and can be adapted to the size and shape of the body, with no Restrictions on aesthetics should occur.

Dies wird dadurch erreicht, dass die Profilholme mittels eines umlaufenden Spannelements zusammengehalten sind, das die Profilholme von der Innenseite des Rahmens her miteinander verspannt. Da das Spannelement an der Innenseite des Rahmens angeordnet ist, kann ohne Beeinflussung des optischen Eindrucks eine einfache und gleichzeitig sichere Verbindung zwischen den Profilholmen geschaffen werden, die wieder leicht lösbar ist.This is achieved in that the profile spars by means of a rotating clamping element are held together, the profile spars from the inside of the frame with each other braced. Since the tensioning element is arranged on the inside of the frame, can be simple and safe at the same time without influencing the visual impression Connection between the profile spars are created, which is easily solvable again.

Im Sinne einer gezielten Kraftübertragung ist es vorteilhaft, dass zwischen den Stirnseiten von zwei aneinandergrenzenden Profilholmen jeweils ein Eckwinkelverbinder angeordnet ist, an dem das Spannelement angreift. In terms of a targeted power transmission, it is advantageous that between the end faces arranged by two adjacent profile beams each corner angle connector is, on which the clamping element acts.

Dadurch, dass jeder Eckwinkelverbinder einen parallel zu den Stirnseiten der angrenzenden Profilholme verlaufenden Hauptsteg aufweist und einen Durchbruch in diesem Hauptsteg aufweist, durch den das Spannelement geführt ist, kann das Spannelement auf einfache Weise ohne weitere Befestigungsmittel am Eckwinkelverbinder angreifen.Due to the fact that each corner connector has a parallel to the end faces of the adjacent Profile spars extending main bridge and has a breakthrough in this main bar has, through which the clamping element is guided, the clamping element can be simple Attempt manner without additional fasteners on the corner bracket.

Jeder Eckwinkelverbinder weist vorzugsweise mindestens ein Paar von Schenkeln auf, die unter einem Winkel zueinander angeordnet sind, der dem Winkel zwischen den angrenzenden Profilholmen entspricht, und jeder Profilholm weist vorzugsweise einen entsprechenden Kanal auf, in welchen der jeweilige Schenkel eingesteckt ist, wodurch eine sichere Verankerung zwischen den Elementen erzeugt wird.Each corner connector preferably has at least one pair of legs which are arranged at an angle to each other, the angle between the adjacent Profile spars corresponds, and each profile spar preferably has a corresponding Channel on, in which the respective leg is inserted, creating a secure anchorage is generated between the elements.

Vorteilhafterweie weist jeder Schenkel eine Rille zur Aufnahme des Spannelementes auf, die zur besseren Führung des Spannelements dient.Advantageously, each leg has a groove for receiving the tensioning element, which serves for better guidance of the clamping element.

Dadurch, dass jeder Eckwinkelverbinder vorzugsweise mindestens ein Paar von Nasen aufweist, die unter einem Winkel zueinander angeordnet sind, der dem Winkel zwischen den angrenzenden Profilholmen entspricht, und dass jeder Profilholm eine entsprechende Spalte aufweist, in welche die jeweilige Nase eingesteckt ist, wird gewährleistet, dass die Verbindung zwischen Eckwinkelverbinder und Profilholm über die gesamte Höhe des Rahmens gleichmäßig gut ist.Characterized in that each corner connector preferably at least one pair of lugs which are arranged at an angle to each other, the angle between corresponds to the adjacent profile beams, and that each profile spar a corresponding Has column in which the respective nose is inserted, it is ensured that the Connection between corner bracket and profile rail over the entire height of the frame is equally good.

Bevorzugt sind die Profilholme und die Eckwinkelverbinder aus wärmeleitendem Material gebildet, so dass die vom umfassten Körper erzeugte Wärme auch über den Rahmen abgeführt werden kann.Preferably, the profile spars and the Eckwinkelverbinder of thermally conductive material formed so that the heat generated by the encompassed body also dissipated through the frame can be.

Jeder Eckwinkelverbinder steht vorzugsweise an seiner Außenwand geringfügig über die Außenwand der angrenzenden Profilholme vor, wodurch scharfe Außenkanten vermieden werden und ein ansprechender optischer Eindruck entsteht.Each corner connector is preferably slightly above its outer wall Outside wall of the adjacent profile spars, thereby avoiding sharp outer edges and creates an appealing visual impression.

Vorzugsweise ist ein Kanal an der Innenwandseite jedes Profilholms angeordnet, in dem das Spannelement verläuft, wobei das Spannelement von der Innenseite des Rahmens her zugänglich ist, so dass die Montage und Demontage leicht durchführbar ist und gleichzeitig das Spannelement den Einbau des flachen Körpers nicht behindert.Preferably, a channel is arranged on the inner wall side of each profile spar, in which the tensioning element extends, the tensioning element coming from the inside of the frame is accessible, so that the assembly and disassembly is easy to carry out and at the same time the clamping element does not hinder the installation of the flat body.

Bei einem Rahmen mit einem rechteckigen Umriss können die Stirnseiten der Profilholme unter einem Winkel von etwa 45° abgeschrägt sein, so dass die Dicke der Eckwinkelverbinder auf ein Mindestmaß reduziert werden kann.In a frame with a rectangular outline, the front sides of the profile spars Beveled at an angle of about 45 °, so that the thickness of the corner angle connector can be reduced to a minimum.

In Fig. 1 ist eine bevorzugte Ausführungsform des erfindungsgemäßen Rahmens 1 dargestellt. Der Rahmen besteht aus vier Profilholmen 3, die an ihren Stirnseiten unter einem Winkel von 45° abgeschrägt sind und über Eckwinkelverbinder 5 miteinander verbunden sind. Insgesamt entsteht so eine rechteckige Rahmenform, die zur Aufnahme von elektrischen/elektronischen Geräten ebenso geeignet ist wie etwa für die Ausbildung von Schaltschranktüren und dergleichen. Besonders geeignet erscheint vor allem der Einsatz bei modernen Flachbildschirmen mit LCD-Displays oder Plasmadisplays. Die Profilholme 3 besitzen eine längliche Form, allerdings ist es auch denkbar, mehr als vier Profilholme 3 miteinander zu verbinden, um einen polygonalen Rahmen 1 für besondere Designs zu schaffen. Die Profilholme 3 bestehen aus einem tragfähigen, widerstandsfähigen Material, das möglichst auch wärmeleitend sein sollte, um gegebenenfalls an der Kühlung der vom Rahmen umfassten elektrischen/elektronischen Einheiten unterstützend mitwirken zu können. Ein bevorzugtes Material, das die geforderten Eigenschaften liefert, ist beispielsweise Aluminium. Von Vorteil ist es auch, wenn der Rahmen 1 dicht gegenüber elektromagnetischer Strahlung ist. In Fig. 1, a preferred embodiment of the frame 1 according to the invention is shown. The frame consists of four profile spars 3, which at their front sides under a Angle of 45 ° are chamfered and connected by Eckwinkelverbinder 5 together are. Overall, this creates a rectangular frame shape for receiving electrical / electronic Devices is just as suitable as for the training of cabinet doors and the same. Above all, the use of modern appears particularly suitable Flat screens with LCD displays or plasma displays. Have the profile struts 3 an elongated shape, but it is also conceivable, more than four profile beams 3 together to create a polygonal frame 1 for special designs. The profile struts 3 are made of a stable, resistant material, the possible should also be heat-conducting, possibly to the cooling of the frame included assisted electrical / electronic units. On For example, preferred material that provides the required properties is aluminum. It is also advantageous if the frame 1 is tight against electromagnetic Radiation is.

Die Eckwinkelverbinder 5 bestehen bevorzugt aus einem harten Kunststoff, der beispielsweise mit Graphitstaub durchmischt ist, um eine bessere Wärmeleitfähigkeit zu erzielen. Ebenso ist der Einsatz von leichten Metallen möglich. Eine genauere Beschreibung der Ausgestaltung der Eckwinkelverbinder 5 wird unter Bezugnahme auf Fig. 2 weiter unten gegeben. Die Verbindung der Rahmenelemente 3, 5 erfolgt durch ein Spannelement 7, das in der dargestellten Ausführungsform an den Eckwinkelverbindern 5 angreift und ringsum in einem Kanal 8 verläuft, der an der Innenwandseite jedes Profilholms 3 ausgebildet ist. Dieser Kanal 8 ist von der Innenseite des Rahmens 1 her zugänglich, so dass von dort eine Bearbeitung des Spannelementes 7 leicht möglich ist, das Spannelement 7 aber dennoch geschützt ist und nicht unnötig viel Platz beansprucht. Das Spannelement 7 ist bevorzugt als Spannband mit hoher Reissfestigkeit, etwa aus Polyester, ausgebildet, allerdings ist auch ein Einsatz von Stahlbändern, Spannseilen oder Spanndrähten denkbar. Das Spannelement 7 kann auch lediglich oder zusätzlich an verschiedenen Punkten direkt an den Profilholmen 3 angreifen, muss aber immer an zumindest einer Stelle von der Innenseite des Rahmens 1 her zugänglich sein.The Eckwinkelverbinder 5 are preferably made of a hard plastic, for example mixed with graphite dust to achieve better thermal conductivity. Likewise, the use of light metals is possible. A more detailed description of Configuration of the corner angle connector 5 will be described below with reference to FIG. 2 given. The connection of the frame members 3, 5 is effected by a clamping element 7, the engages in the illustrated embodiment of the Eckwinkelverbindern 5 and all around in a channel 8 which is formed on the inner wall side of each profile spar 3. This Channel 8 is accessible from the inside of the frame 1 ago, so that from there a Processing of the clamping element 7 is easily possible, the clamping element 7 but still is protected and does not take up unnecessarily much space. The clamping element 7 is preferred as a strap with high tensile strength, such as polyester, formed, however, is It is also conceivable to use steel strips, tensioning cables or tensioning wires. The tensioning element 7 can also only or additionally at different points directly to the profile spars 3 attack, but must always at least one point from the inside of the Be accessible frame 1 ago.

Wie aus Fig. 2 am besten ersichtlich, weist der Eckwinkelverbinder 5 nach der bevorzugten Ausführungsform des erfindungsgemäßen Rahmens 1 einen Hauptsteg 9 auf, dessen Seitenflächen sich parallel zu den Stirnseiten der angrenzenden Profilholme 3 erstrecken und mit diesen in Kontakt kommen. Im Hauptsteg 9 ist ein Durchbruch 11 gefertigt, der zur Durchführung des Spannelements 7 und somit zur Kraftaufnahme dient. Im oberen Bereich weist der Eckwinkelverbinder 5 zwei unter 90° (bei mehr Profilholmen entsprechend größerer Winkel) zueinander angeordnete Schenkel 13 auf, die auf ihrer nach außen gerichteten Seite eine Rille 15 aufweisen, die zur Aufnahme des Spannelements 7 und dessen Führung zum Durchbruch 11 dienen. Anstelle der beschriebenen Geometrie ist es auch möglich, das Spannelement 7 über eine gesonderte Befestigungsvorrichtung mit den Eckwinkelverbindern 5 zu verbinden. Die Schenkel 13 dienen in jedem Fall zum Einstecken in die Profilholme 3, wie später noch detaillierter beschrieben wird. Zur besseren Stabilisierung und zur Gleichverteilung der Kraftübertragung zwischen Eckwinkelverbindern 5 und Profilholmen 3 weisen die Eckwinkelverbinder 5 bevorzugt weitere Nasen auf, die zum Einstecken in die Profilholme 3 dienen. In der dargestellten bevorzugten Ausführungsform sind zwei Nasen 17 im unteren Bereich des Hauptstegs 9 angeordnet und spannen denselben Winkel auf wie die Schenkel 13. An einem auskragenden Arm 19 am oberen Ende des Eckwinkelverbinders 5 sind zwei weitere Nasen 21 angeordnet, die eine Führungs- und Abstützfunktion bei der Montage des zu tragenden flachen Körpers erfüllen. Die Außenwandseite des Eckwinkelverbinders 5 ist an die Form der Profilholme 3 angepaßt; es ergeben sich hierfür keine geometrischen Beschränkungen, so dass alle möglichen Designwünsche erfüllbar sind.As best seen in FIG. 2, the corner connector 5 is the preferred one Embodiment of the frame 1 according to the invention a main web 9, whose side surfaces extend parallel to the end faces of the adjacent profile beams 3 and come in contact with these. In the main web 9, a breakthrough 11 is made, the Implementation of the clamping element 7 and thus serves to absorb power. In the upper area the corner angle connector 5 has two at 90 ° (with more profile spars correspondingly larger Angle) to each other arranged legs 13 which are directed on their outward Side have a groove 15, which is for receiving the clamping element 7 and its leadership to breakthrough 11 serve. Instead of the described geometry, it is also possible that Clamping element 7 via a separate fastening device with the Eckwinkelverbindern 5 to connect. The legs 13 are used in any case for insertion into the profile spars 3, as described in more detail later. For better stabilization and for Uniform distribution of power transmission between corner brackets 5 and 3 profile rails the Eckwinkelverbinder 5 preferably further noses, which are for insertion into the Profile rails 3 serve. In the illustrated preferred embodiment, there are two tabs 17 arranged in the lower region of the main web 9 and span the same angle as the legs 13. On a cantilevered arm 19 at the upper end of Eckwinkelverbinders 5, two further lugs 21 are arranged, which has a guiding and supporting function during assembly of the flat body to be carried out. The outer wall side of the Eckwinkelverbinders 5 is adapted to the shape of the profile struts 3; there are no geometric constraints, so that all possible design wishes can be fulfilled.

Der in Fig. 3 im Querschnitt dargestellte Profilholm 3 weist einen Kanal 8 auf, in den ein Schenkel 13 des Eckwinkelverbinders 5 einsteckbar ist. Dieser Kanal 8 ist in der bevorzugten Ausführungsform gleichzeitig zur Aufnahme des Spannelements 7 geeignet und zur Innenseite des Rahmens 1 hin offen, jedoch können auch zwei unterschiedliche Kanäle vorgesehen sein, von denen einer zum Einstecken der Schenkel und der andere zur Aufnahme des Spannelements 7 dient. Der Profilholm 3 weist an seiner Außenseite eine beliebige Form auf, so dass etwa Kühlprofilelemente angeordnet sein können. Im Profilholm 3 sind Spalten 27 entsprechend der Anzahl ihm zugewandter Nasen 17 des Eckwinkelverbinders 5 ausgebildet, die zur Aufnahme der Nasen 17 dienen. Außerdem können Abstandshalterleisten 25 für den einzuführenden flachen Körper an einer nach innen auskragenden Deckplatte 29 am oberen Ende des Profilholms 3 ausgebildet sein.The profile spar 3 shown in cross-section in FIG. 3 has a channel 8 into which a Leg 13 of Eckwinkelverbinders 5 can be inserted. This channel 8 is in the preferred Embodiment simultaneously suitable for receiving the clamping element 7 and the Inside of the frame 1 out open, but also two different channels be provided, one of which for inserting the legs and the other for receiving of the clamping element 7 is used. The profile spar 3 has on its outside any Shape, so that can be arranged approximately cooling profile elements. In the profile spar 3 Columns 27 are corresponding to the number of noses 17 facing the Eckwinkelverbinders him 5, which serve to receive the lugs 17. In addition, spacer strips can 25 for the inserted flat body on an inwardly projecting Cover plate 29 may be formed at the upper end of the profile spar 3.

Der in Fig. 4 dargestellte Querschnitt gemäß Linie A-A aus Fig. 1 zeigt einen Profilholm 3, in den ein Eckwinkelverbinder 5 eingesteckt ist. Dabei steckt der Schenkel 13 des Eckwinkelverbinders 5 im Kanal 8, während die Nase 17 in Spalte 27 steckt. Das Spannelement 7 ist in der Rille 15 geführt und verläuft durch Durchbruch 11. Vorzugsweise steht die Außenwand des Eckwinkelverbinders leicht nach außen über die Außenwand der Profilholme 3 vor, wodurch scharfe Kanten vermieden werden.The cross section shown in Fig. 4 according to line A-A of FIG. 1 shows a profile spar 3, in which a corner connector 5 is inserted. In this case, the leg 13 of Eckwinkelverbinders inserted 5 in the channel 8, while the nose 17 is in column 27. The clamping element 7 is guided in the groove 15 and passes through aperture 11. Preferably, the outer wall is of the Eckwinkelverbinders slightly outward on the outer wall of the profile spars 3, which avoids sharp edges.

In Fig. 5 ist eine perspektivische Detailansicht einer Eckverbindung des Rahmens aus Fig. 1 dargestellt, wobei ein Profilholm zur besseren Darstellung der mechanischen Ausgestaltung weggelassen wurde. Wiederum ist deutlich zu erkennen, wie das Spannband 7 in der Rille 15 des Schenkels 13 zum Durchbruch 11 geführt wird, durch diesen hindurchtritt und auf der anderen Seite über den anderen Schenkel 13 wieder weggeführt wird.In Fig. 5 is a detailed perspective view of a corner joint of the frame of FIG. 1, wherein a profile spar for better representation of the mechanical design was omitted. Again, it can be clearly seen how the strap 7 in the Groove 15 of the leg 13 is guided to the opening 11, passes through it and on the other side is led away over the other leg 13 again.

Der Zusammenbau eines erfindungsgemäßen Rahmens 1 erfolgt durch folgende Schritte. Zunächst werden zwei Eckwinkelverbinder 5 in einen Profilholm 3 gesteckt. Daraufhin werden zwei weitere Profilholme 3 auf die vormontierten Eckwinkelverbinder 5 gesteckt. Schließlich wird der letzte Profilholm 3 mit zwei Eckwinkelverbindern 5 versehen und über diese mit dem Rahmengrundgerüst verbunden. Das noch nicht als geschlossenes Band ausgebildete Spannelement 7 wird entweder schon vor dem ersten Arbeitsschritt oder nachträglich in die Rillen 15 der Schenkel 13 eingelegt und durch die Durchbrüche 11 geführt. Wenn die Rahmenelemente 3, 5 ineinanderstecken, wird das Spannband straff gespannt und dessen Enden verbunden, wozu handelsübliche Vorrichtungen verwendet werden können. Dadurch werden die Eckwinkelverbinder 5 zeitgleich in Richtung Rahmeninnenseite gezogen und fest an die Stirnseiten der Profilholme 3 gepresst. Der zu halternde flache Körper wird auf der Rückwand des Gehäuses vormontiert, mit dieser zusammen in den Rahmen eingeführt und dort mit üblichen Methoden befestigt.The assembly of a frame 1 according to the invention is carried out by the following steps. First, two Eckwinkelverbinder 5 are inserted into a profile spar 3. Thereupon become two more profile rails 3 are placed on the preassembled Eckwinkelverbinder 5. Finally, the last profile spar 3 is provided with two Eckwinkelverbindern 5 and over these connected to the frame framework. Not yet as a closed volume Trained clamping element 7 is either before the first step or subsequently inserted into the grooves 15 of the legs 13 and passed through the apertures 11. When the frame members 3, 5 nest, the tension band is taut and its ends connected using commercially available devices can. As a result, the corner angle 5 at the same time in the direction of the frame inside pulled and pressed firmly against the front sides of the profile rails 3. The holder to be kept flat body is preassembled on the back wall of the housing, with this together in introduced the frame and fixed there with conventional methods.

Es ist auch möglich, ohne Zwischenschaltung von Eckwinkelverbindern die Profilholme direkt miteinander zu verbinden, wobei das Spannelement dann direkt an diesen angreift. Dies ist etwa beim Zusammenbau von Schaltschranktüren verwirklichbar, wo bevorzugt ein Metalldraht als Spannelement verwendet wird.It is also possible, without the interposition of Eckwinkelverbindern the profile spars directly connect to each other, wherein the clamping element then acts directly on this. This is about realizable in the assembly of cabinet doors, where preferably a Metal wire is used as a clamping element.

Somit wird auf kostengünstige Art und Weise ein Rahmen zur Aufnahme flacher Körper geschaffen, dessen Einzelteile sehr fest und sicher miteinander verbunden sind, der aber auch leicht wieder demontierbar ist.Thus, in a cost effective manner, a frame for receiving flat body created whose items are very firmly and safely connected to each other, but Also easy to disassemble again.
