Description

Die Erfindung bezieht sich auf einen Steckverschluß zur lösbaren Verbindung zweier ineinandersteckbarer Bauteile oder länglicher Gegenstände, wie z.B. Profilstäbe für Regale, Gestelle oder Zeltstangen oder einer zweiteiligen Schnalle. Hierbei kommt es darauf an, daß die Verbindung leicht herstellbar und ebenso leicht lösbar ist und daß die Verbindung selbstverständlich fest und auch gegen Verdrehung stabil ist.The invention relates to a plug closure for detachable connection two interlocking components or elongated objects, e.g. Profile bars for shelves, frames or tent poles or a two-part buckle. It is important that the connection is easy to produce and also is easily detachable and that the connection is of course firm and also against Twist is stable.

Derartige Steckverschlüsse bestehen üblicherweise aus einem im Querschnitt u-förmigen Aufnahmeteil und einem in dieses einführbaren Steckteil, wobei an der Außenwand des Steckteils eine nach innen auffederbare Rastplatte mit entgegen der Einsteckrichtung weisender Rastfläche angeformt ist und in der Außenwand des Aufnahmeteils eine der Rastnase entsprechende Aussparung mit entgegengerichteter Rastfläche vorgesehen ist, in welche die Rastnase beim Einführen des Steckteils aufgrund der Federwirkung selbsttätig einrastbar ist.Such plug closures usually consist of a U-shaped cross section Receiving part and a plug-in part which can be inserted into this, at which Outside wall of the plug-in part with an inward spring-loaded locking plate the insertion direction facing locking surface is formed and in the outer wall of the receiving part a recess corresponding to the locking lug with the opposite direction Locking surface is provided, in which the locking lug when inserting the Plug part can be automatically locked due to the spring action.

Ein derartiger Steckverschluß ist beispielsweise bekannt durch FR - 2 501 484, welche eine Schnalle aus Kunststoff zeigt. Die Rastplatte ist hierbei mit einem Steg starr am Steckteil angeformt und mit einer Druckplatte versehen, welche voll in die Aussparung des Aufnahmeteils eintaucht und mit der Außenwand abschließt, wobei eine flexible Platte im Aufnahmeteil die Rastplatte in Schließposition drückt.Such a plug closure is known for example from FR - 2 501 484 , which shows a buckle made of plastic. The locking plate is rigidly formed on the plug-in part with a web and provided with a pressure plate which plunges fully into the recess of the receiving part and closes with the outer wall, a flexible plate in the receiving part pressing the locking plate in the closed position.

Zum Öffnen der Schnalle wird die Druckplatte so weit nach innen gedrückt, bis die Rastflächen außer Eingriff kommen und die Druckplatte sich aus der Öffnung des Aufnahmeteils herausziehen läßt. Bei diesem Steckverschluß wird es als Nachteil empfunden, daß die Sicherheit des Verschlusses von nur einer Rastnase und der flexiblen Platte abhängt, welche die Rastnase in Schließposition hält. Bricht diese flexible Platte oder der Rastnasensteg, so geht der Verschluß von selbst auf. Auch ist der Eingriff des Steckteils in das Aufnahmeteil relativ kurz, so daß die Verbindung auch nicht als verdrehsicher angesehen werden kann, was insbesondere bei Regalstäben wichtig ist.To open the buckle, the pressure plate is pressed in until the Detent surfaces come out of engagement and the pressure plate comes out of the opening of the Pull out the receiving part. With this plug closure, it becomes a disadvantage felt that the safety of the closure of only one latch and the flexible plate that holds the latch in the closed position. Breaks this flexible plate or the locking nose bridge, so the lock opens by itself. The engagement of the plug part in the receiving part is relatively short, so that the Connection can also not be regarded as secure against rotation, which in particular is important for shelf bars.

Aufgabe der Erfindung ist es daher, den vorliegenden Verschluß so zu gestalten, daß die Sicherheit der Verbindung erhöht und der Verdrehschutz verbessert wird und gleichzeitig die leichte Demontierbarkeit erhalten bleibt. The object of the invention is therefore to design the present closure so that the security of the connection is increased and the anti-rotation protection is improved and at the same time easy dismantling is retained.

Diese Aufgabe wird nach der vorliegenden Erfindung dadurch gelöst, daß am Steckteil in Verlängerung der ersten Rastplatte eine zweite, nach innen auffederbare Rastnase vorgesehen ist, welcher in der Außenwand des Aufnahmeteils ein entsprechendes Loch zugeordnet ist.This object is achieved according to the present invention in that on Plug-in part in extension of the first locking plate, a second one that can be opened inwards Latch is provided, which is in the outer wall of the receiving part corresponding hole is assigned.

Hierdurch erhöht sich nicht nur die Sicherheit, sondern verlängert sich gleichzeitig auch die Eindringtiefe des Steckteils in das Aufnahmeteil, so daß damit auch der Schutz gegen Verwindung bezw. Verdrehung vergrößert wird.This not only increases security, but also extends it at the same time also the depth of penetration of the plug-in part in the receiving part, so that the Protection against torsion Twist is increased.

Zum Öffnen des Verschlusses müssen beide Rastteile gleichzeitig außer Eingriff gebracht werden. Um diesen Handgriff zu vereinfachen, ist in weiterer Ausgestaltung der Erfindung vorgesehen, daß die zweite Rastnase auf einem separaten Steg angeordnet ist, welcher einerends am vorderen Bereich der Querwand angeformt ist und sich mit seinem freien Ende in Richtung auf die Rastplatte erstreckt, wobei der Steg an seienm freien Ende nach unten stufenförmig abgewinkelt ist und mit diesem Ende bis unterhalb der erstgenannten Rastplatte reicht. Hierdurch wird auf einfache Weise erreicht, daß die zweite Rastnase beim Niederdrücken der ersten Rastplatte von dieser miterfaßt und damit gleichzeitig niedergedrückt wird.To open the lock, both locking parts must be disengaged at the same time to be brought. To simplify this handle, is in a further embodiment the invention provided that the second latch on a separate A web is arranged, which is integrally formed on the front area of the transverse wall and extends with its free end towards the locking plate, the web at its free end is angled downwards in steps and extends with this end to below the first-mentioned locking plate. Hereby is achieved in a simple manner that the second latch when depressed the first locking plate of this also recorded and thus depressed at the same time becomes.

Der in den Figuren dargestellte Steckverschluß dient zur lösbaren Verbindung zweier ineinandersteckbarer Bauteile wie bei einer zweiteiligen Schnalle. Der Verschluß ist ebenso verwendbar bei der Verbindung länglicher Gegenstände wie z.B. Profilstäbe für Regale, Gestelle oder Zeltstangen oder der verschiebbaren Verrastung eines Kopfstützengestänges in der Rückenlehne.The plug closure shown in the figures is used for detachable connection two components that can be plugged into each other like a two-part buckle. The Closure can also be used in the connection of elongated objects such as e.g. Profile bars for shelves, frames or tent poles or the sliding Locking a headrest linkage in the backrest.

Der Steckverschluß besteht hierbei aus einem an dem zu verbindenden Bauteil angeformten oder sonstwie befestigten Aufnahmeteil 1 und einem in dieses einführbaren und verrastbaren Steckteil 2, welches mit dem anderen zu verbindenden Bauteil in geeigneter Weise verbunden ist. Das Aufnahmeteil 1 besitzt im Ausführungsbeispiel nach den Figuren 1 bis 5 einen U-förmigen Profilquerschnitt, wobei die freien Kanten 5 der Seitenwände 3 nach innen umgebogen sind. Die Querwand 4, die im vorderen Einsteckbereich eine Einführschräge 6 aufweist, besitzt ein etwa rechteckiges Loch 7 und daran anschließend ein weiteres, ebenfalls rechteckiges Loch 8, welches jedoch wesentlich kleiner ist als das erstgenannte Loch 7. The plug-in closure consists of a receiving part 1 molded or otherwise fastened to the component to be connected and a plug-in part 2 which can be inserted and locked therein and which is connected in a suitable manner to the other component to be connected. In the exemplary embodiment according to FIGS. 1 to 5, the receiving part 1 has a U-shaped profile cross section, the free edges 5 of the side walls 3 being bent inwards. The transverse wall 4, which has an insertion bevel 6 in the front insertion area, has an approximately rectangular hole 7 and then another, likewise rectangular hole 8, which is, however, considerably smaller than the first-mentioned hole 7.

Das Steckteil 2 besitzt ebenfalls ein im Querschnitt u-förmiges Körperteil, dessen Querwand 9 und deren Seitenwände 10 so bemessen sind, daß das Steckteil 2 schubladenartig in die Öffnung 26 des Aufnahmeteils 1 eingesteckt werden kann. Die Querwand 9 ist hierbei entlang beider Kanten durch Aussparungen 11 und 12 unterbrochen, welche im Abstand "A" von der Vorderkante 13 der Querwand 9 beginnen und bis etwa zur Hälfte der Seitenwände 10 heruntergezogen sind. Das Steckteil 1 ist an seinem - in Einsteckrichtung gesehen - hinteren Ende 14 an einem länglichen Gegenstand 15 angeformt oder eingeschoben, wobei dieser Gegenstand eine Stange, ein Balken oder Stab sein kann und im vorliegenden Fall genau wie das Aufnahmeteil 1 einen U - förmigen Profilquerschnitt besitzt.The plug-in part 2 also has a cross-sectionally U-shaped body part, the transverse wall 9 and the side walls 10 of which are dimensioned such that the plug-in part 2 can be inserted into the opening 26 of the receiving part 1 in the manner of a drawer. The transverse wall 9 is interrupted along both edges by recesses 11 and 12 which begin at a distance "A" from the front edge 13 of the transverse wall 9 and are pulled down to approximately half of the side walls 10 . The plug-in part 1 is formed or pushed in at its rear end 14 , as seen in the plug-in direction, on an elongated object 15 , which object can be a rod, a bar or a rod and, in the present case, has a U-shaped profile cross section, just like the receiving part 1 .

Am hinteren Ende 14 der Querwand 9 ist ein flexibler Steg 16 mit einer Rastplatte 17 angeformt, wobei der Steg senkrecht zur Querwand 9 nach innen wegfedern kann. Auf der in Einsteckrichtung des Steckteils 2 rückwärtigen Seite der Rastplatte 17 befindet sich eine Rastfläche 18, welche beim Einrasten der Rastplatte 17 im Loch 7 des Aufnahmeteils 1 an der entsprechenden Rastfläche 19 des Loches 7 anliegt. Die Rastplatte 17 ist in ihrer Form so gestaltet, daß diese voll in das Loch 7 eintaucht und mit einer gewölbten Druckfläche 20 über die Querwand 4 des Aufnahmeteils 1 vorsteht.At the rear end 14 of the transverse wall 9 , a flexible web 16 is formed with a locking plate 17 , the web being able to spring inwards perpendicularly to the transverse wall 9 . On the rear in the insertion direction of the male part 2 side of the detent plate 17 is a latching surface 18 which abuts the hole 7 during the engagement of the latch plate 17 in the hole 7 of the female part 1 at the corresponding latching surface nineteenth The locking plate 17 is designed in such a way that it dips fully into the hole 7 and protrudes with a curved pressure surface 20 over the transverse wall 4 of the receiving part 1 .

Vom vorderen Bereich der Querwand 9 erstreckt sich in Richtung auf die Rastplatte 17 ein zweiter, separater Steg 21, der auf seiner Oberseite eine Rastnase 22 aufweist. Diese Rastnase 22 besitzt auf der gleichen Seite wie die Rastplatte 17 eine Rastfläche 23 und auf der anderen - in Einsteckrichtung gesehen - vorderen Seite eine Schrägfläche 24. Der separate Steg 21 ist in Richtung auf die Rastplatte 17 verlängert und so abgewinkelt, daß das abgewinkelte Ende 25 bis unterhalb der Rastplatte 17 reicht und beim Niederdrücken von dieser miterfaßt wird.From the front area of the transverse wall 9 is a second, separate web 21 having on its upper side a latching lug 22 extends toward the latch plate 17th This locking lug 22 has on the same side as the locking plate 17 a locking surface 23 and on the other - seen in the insertion direction - front side an inclined surface 24. The separate web 21 is extended in the direction of the locking plate 17 and angled so that the angled end 25 extends below the locking plate 17 and is included in this when depressed.

Beim Zusammenführen des Steckverschlusses wird das Steckteil 2 mit seiner Vorderkante 13 voraus in die Einstecköffnung 26 des Aufnahmeteils 1 eingeführt. Dabei werden die Rastnase 22 und die Rastplatte 17 entlang der Einführschräge 6 nach unten weggedrückt. Sobald das Steckteil 2 im Aufnahmeteil 1 seine Verschlußstellung erreicht hat, federn die Rastplatte 17 und die Rastnase 22 in ihre Ausgangslage hoch und tauchen dabei in ihre entsprechenden Rastlöcher 7 und 8 ein (siehe Figuren 2 und 5 ). Da die Rastnase 22 und die Rastplatte 17 auf separaten Stegen 21 und 16 angeordnet sind, ist der Verschluß doppelt gesichert. Falls einer der beiden Stege 16 oder 21 bricht, wird der Verschluß immer noch durch den zweiten Steg gehalten.When the plug closure is brought together, the plug part 2 is inserted with its front edge 13 ahead into the insertion opening 26 of the receiving part 1 . The locking lug 22 and the locking plate 17 are pushed down along the insertion slope 6 . As soon as the plug-in part 2 in the receiving part 1 has reached its closed position, the locking plate 17 and the locking lug 22 spring up into their starting position and plunge into their corresponding locking holes 7 and 8 (see FIGS. 2 and 5 ). Since the locking lug 22 and the locking plate 17 are arranged on separate webs 21 and 16 , the closure is secured twice. If one of the two webs 16 or 21 breaks, the closure is still held by the second web.

Will man den Verschluß lösen, so genügt es, die Rastplatte 17 nach unten zu drücken. Dabei wird das abgewinkelte Stegende 25 der Rastnase 22 mit nach unten gedrückt, so daß beide Rastflächen 19 und 23 außer Eingriff kommen und das Steckteil 2 leicht aus dem Aufnahmeteil 1 herausgezogen werden kann. If you want to release the closure, it is sufficient to press the locking plate 17 down. The angled web end 25 of the locking lug 22 is pressed downward, so that both locking surfaces 19 and 23 come out of engagement and the plug-in part 2 can be easily pulled out of the receiving part 1 .

In den Figuren 6 bis 10 ist ein etwas anders geformter Steckverschluß dargestellt, welcher beispielsweise zur lösbaren Halterung von Regalstäben verwendet werden kann. Das Aufnahmeteil 27 hat hierbei einen etwa halbrunden Profilquerschnitt und besitzt ebenfalls eine Einführschräge 28, ein etwa ovales Rastloch 29 und dahinter eine etwa rechteckige Rastnische 30. Das Aufnahmeteil 27 besitzt an der Innenseite mindestens zwei gegenüberliegende Führungsrillen 31.FIGS. 6 to 10 show a slightly differently shaped plug closure which can be used, for example, for releasably holding shelf bars. The receiving part 27 here has an approximately semicircular profile cross section and also has an insertion bevel 28, an approximately oval latching hole 29 and behind it an approximately rectangular latching niche 30. The receiving part 27 has at least two opposite guide grooves 31 on the inside.

Das Steckteil 33 besitzt ebenfalls einen etwa halbrunden Profilquerschnitt und ist so geformt, daß es sich schubladenartig in das Aufnahmeteil 21 einführen läßt. Das Steckteil 33 ist - genau wie das Steckteil 2 - mit einer Rastplatte 34 und einer Rastnase 35 versehen, welche im Schließzustand in das Loch 29 bzw. die Rastnische 30 einrasten.The plug-in part 33 also has an approximately semicircular profile cross section and is shaped such that it can be inserted into the receiving part 21 in the manner of a drawer. The plug-in part 33 is - just like the plug-in part 2 - provided with a locking plate 34 and a locking lug 35 which engage in the hole 29 or the locking recess 30 in the closed state.

Das Steckteil 33 besitzt an der Außenwand Führungsrippen 32, welche beim Einführen des Steckteils 33 in die Führungsrillen 31 eingreifen und damit für eine zusätzliche Erhöhung der Verdrehstabilität sorgt. Desweiteren kann auf der Außenwand des Steckteils 33 in Einsteckrichtung hinter der Rastplatte 34 noch eine kurze Führungsrippe 32' angeformt sein, welche beim Einführen des Steckers 33 in eine entsprechende Rille 31' in der Außenwand des Aufnahmeteils 27 eingreift. Das Steckteil 33 ist an einem in der Zeichnung lediglich angedeuteten Endstück 36 angeformt, welches dazu dient, einen nichtdargestellten Regalstab aufzunehmen.The plug-in part 33 has guide ribs 32 on the outer wall , which engage when the plug-in part 33 is inserted into the guide grooves 31 and thus provides an additional increase in the rotational stability. Furthermore, a short guide rib 32 ' can be formed on the outer wall of the plug-in part 33 in the insertion direction behind the locking plate 34 , which engages in a corresponding groove 31' in the outer wall of the receiving part 27 when the plug 33 is inserted. The plug-in part 33 is formed on an end piece 36 , which is only indicated in the drawing and which serves to receive a shelf rod (not shown).

Bei dem in den Figuren 11 und 12 gezeigten Ausführungsbeispiel besitzt der Stecker 33' den gleichen Profilquerschnitt wie der Stecker 33 in den Figuren 6 und 8. Allerdings sind hierbei am separaten Steg 21 über einen halbrunden Bügel 38 zwei Rastnasen 39 angeformt, welche an der Einsteckseite in Einsteckrichtung derart abgeschrägt sind, daß diese beim Einführen des Steckteils in die Führungsrillen 31 eintreten und im Schließzustand in entsprechende Nischen 40 neben den Führungsrillen 32 ( siehe Figur 7 ) eintauchen, um dadurch eine zusätzliche Verriegelung zu bewirken.In the exemplary embodiment shown in FIGS. 11 and 12 , the plug 33 'has the same profile cross section as the plug 33 in FIGS. 6 and 8. However, two detents 39 are formed on the separate web 21 via a semicircular bracket 38 , which are on the insertion side are bevelled in the direction of insertion such that they enter the guide grooves 31 when the plug-in part is inserted and, in the closed state, plunge into corresponding niches 40 next to the guide grooves 32 (see FIG. 7) , in order thereby to effect an additional locking.
