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, the frame consisting of essentially straight profile bars exists, which are connected to each other at their end faces.

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, wie beispielweise aus der US-6,181,390 bekannt. 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 holding electrical or electronic devices used. In particular flat display elements such as LCD displays or plasma displays are arranged in a housing that has a frame and a rear wall, as is known, for example, from US Pat. No. 6,181,390. Here either suitable plastics or preferably parts made of light metal. When making the frame the profile spars were previously welded to one another directly or via corner angle connectors, glued or pressed to establish a secure connection. This requires a relatively high amount of work and cost in assembly, and disassembly difficult or impossible at all without destroying the frame.

Aus der DE 70 00 649 U ist ein Rahmen bekannt, insbesondere für Fenster, Türen oder Fertigbauelemente, dessen Rahmenteile ohne Eckwinkelverbinder miteinander verbunden und die durch ein offenes, mit einem Spannschloß verstellbares Spannband verspannt sind. Die Zugänglichkeit zum Spannband ist eingeschränkt, wodurch ein Festzurren oder ein Austauschen des Spannbandes nur mit erhöhtem Aufwand möglich ist.A frame is known from DE 70 00 649 U, in particular for windows, doors or Prefabricated components, the frame parts of which are connected to one another without corner angle connectors and which are braced by an open, adjustable tensioning strap. Access to the strap is restricted, causing a lashing or a Replacing the strap is only possible with increased effort.

Den nächstkommenden Stand der Technik bildet die FR-A-2 529 626, die ein Tor oder eine ähnliche Konstruktion beschreibt. Vier umlaufende Hohlprofile sind hier über Eckwinkelverbinder miteinander verbunden und durch ein nicht dehnbares Kabel zusammengespannt. Das Kabel ist hierbei durch Öffnungen in den Eckwinkelverbindern gespannt, wobei es in einem der Eckwinkelverbinder mit seinem als Schlaufe ausgebildeten einen Ende um einen Stift geschlungen ist, und im selben Eckwinkelverbinder mit seinem anderen Ende in eine Haltevorrichtung gequetscht ist, die über eine geeignete Verstelleinrichtung derart nachstellbar ist, daß das Kabel in gewissem Umfang nachgespannt werden kann. Die Profilholme sind nicht von der Innenseite des Rahmens her zugänglich, so daß eine einfache Montage oder ein Austausch des Kabels innerhalb der Profilholme nicht möglich ist.The closest prior art is FR-A-2 529 626, which is a gate or one describes similar construction. Four circumferential hollow profiles are here via corner angle connectors connected to each other and clamped together by a non-stretchable cable. The cable is stretched through openings in the corner angle connectors, whereby it is in one of the corner angle connectors with its end formed as a loop around one Pin is looped, and in the same corner bracket connector with its other end in one Holding device is squeezed, which can be adjusted in this way using a suitable adjusting device is that the cable can be retightened to a certain extent. The profile bars are not accessible from the inside of the frame, making installation easy or it is not possible to exchange the cable within the profile bars.

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 of a frame for mounting to create a flat body that can be assembled and disassembled with simple means is and which can be flexibly adapted to the size and shape of the body, but none Restrictions on aesthetics are said to 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. Dabei ist im Sinne einer gezielten Kraftübertragung zwischen den Stirnseiten von zwei aneinandergrenzenden Profilholmen jeweils ein Eckwinkelverbinder angeordnet, an dem das Spannelement angreift. An der Innenwandseite jedes Profilholms ist ein Kanal 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. 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 circumferential clamping element are held together by the profile spars from the inside of the frame braced. It is in the sense of a targeted power transmission between the end faces one corner angle connector is arranged from each of two adjoining profile bars, on which the clamping element engages. There is a on the inside wall side of each profile spar Channel arranged in which the clamping element runs, the clamping element of the Inside of the frame is accessible, making assembly and disassembly easy is feasible and at the same time the clamping element does not include the installation of the flat body with special needs. Since the clamping element is arranged on the inside of the frame, without Influencing the visual impression a simple and at the same time secure connection be created between the profile spars, which is again easily detachable.

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.The fact that each corner bracket connector one parallel to the end faces of the adjacent Has profile spars extending main web and a breakthrough in this main web has, through which the clamping element is guided, the clamping element can easily Attack the corner bracket connector without further fasteners.

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 bracket connector preferably has at least one pair of legs that are arranged at an angle to each other that is the angle between the adjacent Profile bars corresponds, and each profile bar preferably has a corresponding one Channel in which the respective leg is inserted, which ensures secure anchoring is generated between the elements.

Vorteilhafterweie weist jeder Schenkel eine Rille zur Aufnahme des Spannelementes auf, die zur besseren Führung des Spannelements dient.Each leg advantageously has a groove for receiving the tensioning element, which serves to better guide the tensioning 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.The fact that each corner bracket connector preferably has at least one pair of lugs has, which are arranged at an angle to each other, the angle between corresponds to the adjacent profile spars, and that each profile spar has a corresponding one Gaps, in which the respective nose is inserted, ensures that the Connection between corner bracket connector and profile spar over the entire height of the frame is equally good.

Bevorzugt sind die Profilholme und die Eckwinkeiverbinder aus wärmeleitendem Material gebildet, so dass die vom umfassten Körper erzeugte Wärme auch über den Rahmen abgeführt werden kann.The profile spars and the corner angle connectors made of heat-conducting material are preferred formed so that the heat generated by the enclosed body is also dissipated via 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 bracket connector is preferably on its outer wall slightly above the Outside wall of the adjacent profile spars in front, whereby sharp outer edges are avoided and an appealing visual impression is created.

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 the case of a frame with a rectangular outline, the end faces of the profile bars can beveled at an angle of approximately 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 Eckwinkeiverbinder 5 miteinander verbunden sind. Insgesamt entsteht so eine rechteckige Rahmenform, die zur Aufnahme von elektrischenlelektronischen 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 wärrneleitend 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. 1 shows a preferred embodiment of the frame 1 according to the invention. The frame consists of four profile bars 3, which are under one on their end faces Angles of 45 ° are chamfered and connected to one another via corner angle connectors 5 are. All in all, this creates a rectangular frame shape that is used to hold electronic electronics Devices is just as suitable as for the construction of control cabinet doors and the same. Use with modern ones seems particularly suitable Flat screens with LCD displays or plasma displays. The profile bars 3 have an elongated shape, but it is also conceivable to have more than four profile bars 3 with one another to connect to create a polygonal frame 1 for special designs. The profile bars 3 are made of a load-bearing, resistant material that is as possible should also be thermally conductive in order to cool the frame if necessary to be able to support the electrical / electronic units. On preferred material that provides the required properties is, for example, 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.The corner angle connector 5 are preferably made of a hard plastic, for example is mixed with graphite dust in order to achieve better thermal conductivity. The use of light metals is also possible. A more detailed description of the The configuration of the corner angle connector 5 is described below with reference to FIG. 2 given. The connection of the frame elements 3, 5 is carried out by a clamping element 7, the attacks in the illustrated embodiment on the corner angle connectors 5 and all around in runs 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, so that from there Processing of the clamping element 7 is easily possible, but the clamping element 7 is protected and does not take up too much space. The tensioning element 7 is preferred designed as a tension band with high tensile strength, such as polyester, but is it is also conceivable to use steel straps, tension cables or tension wires. The clamping element 7 can also only or additionally at different points directly on the profile bars 3 attack.

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 Eckwinkelverbindem 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 can best be seen from FIG. 2, the corner angle connector 5 has the preferred one Embodiment of the frame 1 according to the invention on a main web 9, the side surfaces extend parallel to the end faces of the adjacent profile bars 3 and come into contact with them. In the main web 9, an opening 11 is made, which for Implementation of the clamping element 7 and thus serves to absorb force. In the upper area the corner angle connector 5 has two under 90 ° (correspondingly larger with more profile bars Angle) to each other arranged legs 13, which on their outward Side have a groove 15 which for receiving the clamping element 7 and its guidance serve for breakthrough 11. Instead of the geometry described, it is also possible that Clamping element 7 via a separate fastening device with the corner bracket connectors 5 to connect. The legs 13 are used in any case for insertion into the profile bars 3, as will be described in more detail later. For better stabilization and Uniform distribution of power transmission between corner angle connectors 5 and profile bars 3 the corner angle connectors 5 preferably have further lugs which can be inserted into the Profile bars 3 serve. In the preferred embodiment shown there are two lugs 17 arranged in the lower region of the main web 9 and span the same angle like the legs 13. On a cantilever arm 19 at the upper end of the corner angle connector 5 two further lugs 21 are arranged, which have a guiding and supporting function when assembling the flat body to be carried. The outer wall side of the corner bracket connector 5 is adapted to the shape of the profile bars 3; there are none for this geometric restrictions, so that all possible design wishes can be met.

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 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 the corner angle connector 5 can be inserted. This channel is 8 at the same time suitable for receiving the clamping element 7 and Inside of the frame 1 open, but can also use two different channels be provided, one for inserting the legs and the other for receiving the clamping element 7 is used. The profile spar 3 has any on its outside Form on, so that cooling profile elements can be arranged. In Profilholm 3 are columns 27 corresponding to the number of lugs 17 of the corner angle connector facing it 5 formed, which serve to receive the lugs 17. Spacer strips can also be used 25 for the flat body to be inserted on an inwardly projecting body 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 from FIG. 1 shows a profile spar 3, in which a corner angle connector 5 is inserted. The leg 13 of the corner angle connector is inserted 5 in channel 8, while nose 17 is in column 27. The clamping element 7 is guided in the groove 15 and runs through an opening 11. The outer wall is preferably standing of the corner angle connector slightly outwards over the outer wall of the profile bars 3 in front, avoiding 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.5 is a perspective detail view of a corner connection of the frame from FIG. 1, wherein a profile spar for a better representation of the mechanical design was omitted. Again, it can be clearly seen how the tension band 7 in the Groove 15 of the leg 13 is guided to the opening 11, passes through this and is led away again on the other side over the other leg 13.

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.A frame 1 according to the invention is assembled by the following steps. First, two corner bracket connectors 5 are inserted into a profile spar 3. Thereupon two further profile bars 3 are placed on the pre-assembled corner bracket connector 5. Finally, the last profile spar 3 is provided with two corner angle connectors 5 and over these are connected to the basic framework. Not as a closed volume yet 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 openings 11. If the frame elements 3, 5 are inserted into one another, the tensioning strap is tensioned tight and its ends connected, for which purpose commercial devices are used can. As a result, the corner bracket connectors 5 are simultaneously towards the inside of the frame pulled and pressed firmly to the end faces of the profile bars 3. The one to be held flat body is pre-assembled on the rear wall of the housing, together with this in introduced the frame and fixed it there with usual methods.

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, a frame for accommodating flat bodies is created in a cost-effective manner created, the individual parts of which are very firmly and securely connected, but the is also easy to dismantle.
