Definitions
- the invention relates to a locking fitting for adjacent frame construction parts with the features specified in the preamble of claim 1.
- the subject of the invention is intended to be used universally as a fitting part for connecting, for example, profile parts in window, door or other frames serving for purposes such as, for example, building up sight and wind protection elements.
- corner connectors are usually used, which are inserted into corresponding longitudinal guides of profile parts to be connected and fixed there in a suitable manner, for example by means of clamping screws, clamping wedges or similar construction elements.
- corner connectors with the features specified in the preamble of claim 1 are in the DE 10 2014 016 508 , EP 3 284 893 A1 or EP 3 121 363 B1 specified.
- the rotary locking element of the locking fitting itself is very simple to cut out from the material of the inner part, for example by punching, but preferably, for example, by laser cutting a flat iron.
- This cutting technique which is now very common, enables very fine and filigree cutting contours, which are ideally suited for the design of the locking element.
- Another advantage of the locking fitting according to the invention lies in the fact that due to the design of the rotary locking element in one piece with the inner part, the latter is held captively on the inner part by means of the retaining web. In connection with the recess in the inner part surrounding it, this holding web has additional functions in accordance with preferred developments of the subject matter of the invention. So it acts together with an angular shape of the recess as a limitation of the angle of rotation of the rotary bolt body.
- the Fig. 1 shows the inner part 1 as the first structural part of a locking device, such as that used as a connector for a frame 2 Fig. 4 is shown as a whole.
- This inner part 1 is produced as a flat iron, which is angled in plan view, from a sheet steel part with a rectangular cross section.
- the two legs 4.1, 4.2 of the flat iron can not only at a right angle, but practically at any angle be arranged to each other, for example to form triangular frames.
- the rotary bolt body 6 On the side of the rotary bolt body 6 facing away from the eccentric surface 8, the latter is connected in one piece to the inner part 1 via a retaining web 9 which is inclined to the radial direction, the retaining web 9 extending parallel to the edge 13a of a recess 10 which widens angularly towards the rotary bolt body 6.
- the locking bar body 6 is provided centrally with an internal hexagon 11 for the engagement of a hexagon key for the rotary actuation of the locking bar body 6.
- Recognizable deformation of the retaining web 9 is simulated a kind of over-center kinematics, which on the one hand ensures that the rotary bolt body 6 is pressed particularly strongly beyond the inner edges 3 and in its 2 and 3 locked position shown is fixed. Basically, by rotating the rotary bolt body 6 against the in Fig. 1 and 2nd Directional arrows shown DR the locking reversible.
- a miter-cut frame profile for example a stable frame for a privacy and wind protection element, is pushed onto the two legs 4.1, 4.2 of the inner part 1 as outer parts 14.
- These outer parts 14 flank the inner part 1 in the area of its flat rectangular cross section, in that the outer parts 14 with shape-adapted guide grooves 15 encompass the outer edges 16 and inner edges 3 facing away from one another.
- Fig. 4 and 6 it becomes clear that the rotary bolt bodies 6 with their hexagon receptacles 11 are still accessible and - as explained above - can be operated in rotation and thus into the 2 to 6 locking position shown are transferred.
- the rotary bolt bodies 6 act with their flanks 12 on the outer parts 14 in the one guide groove 15 and thus form a stable connection between the two outer parts 14.
- FIG. 7 An alternative inner part 1 'is shown, which is designed as a corner connector angle iron with legs 17.1, 17.2 arranged in two mutually perpendicular planes.
- the two legs 17.1, 17.2 can also be oriented at a different, practically arbitrary angle to one another.
- each turn bar elements 5 are formed adjacent to the side edges 18.
- Outer parts (not shown) plugged onto it as profiles for the production of a frame are to be connected stably in the manner explained above.

Description
Die vorliegende Patentanmeldung nimmt die Priorität der deutschen Patentanmeldung
Die Erfindung betrifft einen Verriegelungsbeschlag für aneinander grenzende Rahmenkonstruktionsteile mit den im Oberbegriff des Anspruchs 1 angegebenen Merkmalen.The invention relates to a locking fitting for adjacent frame construction parts with the features specified in the preamble of
Der Erfindungsgegenstand soll dabei universell als Beschlagteil zur Verbindung beispielsweise von Profilteilen bei Fenster-, Tür- oder für andere Zwecke dienenden Rahmen, wie beispielsweise zum Aufbau von Sicht- und Windschutz-Elementen verwendet werden.The subject of the invention is intended to be used universally as a fitting part for connecting, for example, profile parts in window, door or other frames serving for purposes such as, for example, building up sight and wind protection elements.
Hierfür werden üblicherweise Eckverbinder eingesetzt, die in entsprechende Längsführungen von zu verbindenden Profilteilen eingeschoben und dort in geeigneter Weise, beispielsweise durch Klemmschrauben, Klemmkeile oder ähnliche Konstruktionselemente festgelegt werden. Beispiele für solche Eckverbinder mit den im Oberbegriff des Anspruches 1 angegebenen Merkmalen sind in der
Problematisch bei diesen üblichen Beschlagteilen ist die Tatsache, dass die Konstruktionselemente gesonderte Teile sind, für die spezielle Verbindungen, wie Gewinde, an den Beschlagteilen hergestellt werden müssen. Darüber hinaus ist deren Montagetechnik selbst oft aufwendig und - weil die gesonderten Konstruktionselemente verlierbare Einzelteile sind - oft mühselig. Auch werden solche Beschlagteile oft direkt in die zu verbindenden Rahmenteile eingeschraubt, was zu Beeinträchtigungen daran führen kann.The problem with these conventional fitting parts is the fact that the construction elements are separate parts for which special connections, such as threads, have to be produced on the fitting parts. In addition, their assembly technology itself is often complex and - because the separate construction elements are lost parts - often cumbersome. Such fittings are often screwed directly into the frame parts to be connected, which can lead to impairments.
Grundsätzlich besteht also bei solchen als Massenware in großen Stückzahlen eingesetzten Beschlagteilen das Bedürfnis für einen extrem einfach herzustellenden, rationell zu montierenden und dabei im Endmontagezustand sehr stabilen Verriegelungsbeschlag.Basically, there is therefore a need for an extremely simple to manufacture, Lock fitting that is efficient to install and very stable in the final assembly state.
Diese Aufgabe wird laut Anspruch 1 durch einen Verriegelungsbeschlag gelöst, der umfasst
- ein Innenteil als erstes Konstruktionsteil mit einem zumindest abschnittsweise flachrechteckigen Querschnitt, und
- ein Außenteil als zweites Konstruktionsteil, das das Innenteil im Bereich seines flachrechteckigen Querschnittes flankiert, sowie
- mindestens ein im Bereich des flachrechteckigen Querschnittes des Innenteils aus dessen Material durch eine vertikal durchgehende Schnittkontur ausgeschnittenes, damit einstückig ausgeführtes Drehriegelelement, das aufweist
- = einen scheibenförmigen, in einer runden Führungskontur des Innenteiles drehbar geführten, an die das Außenteil flankierende Seitenfläche des Innenteils angrenzenden Drehriegelkörper,
- = eine an einem Umfangsabschnitt des Drehriegelkörpers angelegte, zurückspringende Exzenterfläche, die in der entriegelten Stellung des Drehriegelkörpers mit der flankierenden Seitenflächen des Innenkörpers im Wesentlichen fluchtet und in der durch eine Drehung des Drehriegelkörpers verriegelten Stellung des Drehriegelkörpers sich in die Führungskontur des Innenteiles derart verlagert, dass der Drehriegelkörper mit seiner der Exzenterfläche benachbarten Flanke das Außenteil verriegelnd beaufschlagt, sowie
- = einen eine Aussparung im Innenteil überbrückenden Haltesteg zwischen Drehriegelkörper und Innenteil.
- an inner part as a first structural part with a flat rectangular cross-section at least in sections, and
- an outer part as a second structural part, which flanks the inner part in the area of its flat rectangular cross section, and
- At least one in the area of the flat rectangular cross-section of the inner part, which is cut out of its material by a vertically continuous cutting contour and is therefore made in one piece, which has
- = a disk-shaped rotary bolt body, which is rotatably guided in a round guide contour of the inner part and adjoins the side surface of the inner part flanking the outer part,
- = a recessed eccentric surface applied to a circumferential section of the rotary bolt body, which in the unlocked position of the rotary bolt body is essentially flush with the flanking side surfaces of the inner body and in the position of the rotary bolt body locked by rotation of the rotary bolt body moves into the guide contour of the inner part such that the rotary bolt body with its flank adjacent to the eccentric surface acts on the outer part in a locking manner, and
- = a retaining bridge bridging a recess in the inner part between the rotary bolt body and the inner part.
Einer der Hauptvorteile dieser erfindungsgemäßen Ausgestaltung liegt darin, dass das Drehriegelelement des Verriegelungsbeschlages durch das Ausschneiden aus dem Material des Innenteils selbst sehr einfach, beispielsweise durch Stanzen, bevorzugterweise jedoch etwa durch Laserschneiden aus einem Flacheisen, hergestellt werden kann. Diese mittlerweile sehr übliche Schneidetechnik ermöglicht sehr feine und filigrane Schnittkonturen, die für die Ausbildung des Drehriegelelementes bestens geeignet sind.One of the main advantages of this configuration according to the invention is that the rotary locking element of the locking fitting itself is very simple to cut out from the material of the inner part, for example by punching, but preferably, for example, by laser cutting a flat iron. This cutting technique, which is now very common, enables very fine and filigree cutting contours, which are ideally suited for the design of the locking element.
Ein weiterer Vorteil des erfindungsgemäßen Verriegelungsbeschlages liegt in der Tatsache, dass durch die mit dem Innenteil einstückige Ausbildung des Drehriegelelementes dieses mithilfe des Haltesteges unverlierbar am Innenteil gehalten ist. Dieser Haltesteg hat in Verbindung mit der ihn umgebenden Aussparung im Innenteil gemäß bevorzugten Weiterbildungen des Erfindungsgegenstandes noch zusätzliche Funktionen. So wirkt er zusammen mit einer Winkelform der Aussparung als Begrenzung des Drehwinkels des Drehriegelkörpers. Darüber hinaus bildet er bei seiner Deformation während der Drehung des Drehriegelkörper die Funktion eines KniehebelMechanismus nach, die zum einen für eine zusätzliche Fixierung des Drehriegelkörpers in der verriegelten Übertotpunktstellung und zum anderen für ein zusätzliche Beaufschlagung des Drehriegelkörpers in Richtung zum festzulegenden Außenteil sorgt.Another advantage of the locking fitting according to the invention lies in the fact that due to the design of the rotary locking element in one piece with the inner part, the latter is held captively on the inner part by means of the retaining web. In connection with the recess in the inner part surrounding it, this holding web has additional functions in accordance with preferred developments of the subject matter of the invention. So it acts together with an angular shape of the recess as a limitation of the angle of rotation of the rotary bolt body. In addition, when it is deformed during the rotation of the rotary bolt body, it simulates the function of a toggle lever mechanism, which on the one hand provides additional fixation of the rotary bolt body in the locked over-center position and on the other hand provides additional loading of the rotary bolt body in the direction of the outer part to be fixed.
Schließlich sorgt die nach Art eines Exzenters wirkende Verriegelung zwischen Innen- und Außenteil für eine sehr stabile Verbindung zwischen diesen beiden Bauteilen.Finally, the eccentric locking mechanism between the inner and outer part ensures a very stable connection between these two components.
