Kippankertoogle
Die Erfindung betrifft einen Kippanker zur Hohlraumbefestigung mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a toggle anchor for cavity fastening with the features of the preamble of claim 1.
Ein bekannter Kippanker weist ein balkenartiges Ankerteil in Form eines U-Profilstabs auf. Im Ankerteil ist ein zylindrischer Bolzen um eine gedachte Achse quer zum Ankerteil drehbar gelagert. Der Bolzen weist ein Gewindeloch auf, das den Bolzen quer durchsetzt und in das ein Gewindestab eingeschraubt ist. Der Bolzen ist außermittig zu einem Ende des Ankerteils hin versetzt angeordnet, so dass das Ankerteil auf einer Seite weiter vom Bolzen absteht als auf der anderen Seite.A known tilt anchor has a beam-like anchor part in the form of a U-shaped bar. In the anchor part, a cylindrical bolt is rotatably mounted about an imaginary axis transverse to the anchor part. The bolt has a threaded hole which passes through the bolt transversely and into which a threaded rod is screwed. The bolt is arranged off-center to one end of the anchor part, so that the anchor part protrudes further from the bolt on one side than on the other side.
Zur Hohlraumbefestigung wird das Ankerteil des bekannten Kippankers bezüglich des Gewindestabs so verschwenkt, dass es sich in etwa in einer Linie mit dem Gewindestab befindet und der Gewindestab in einem Innenraum des U-förmigen Ankerteils einliegt. In diesem Zustand wird der Kippanker durch ein Loch in beispielweise einer Gipskartonplatte durchgeführt. Sobald das Ankerteil vollständig durch die Gipskartonplatte durchgeführt ist, schwenkt es schwerkraftbedingt in eine Stellung quer zum Gewindestab. Am Gewindestab wird der Kippanker so weit zurückgezogen, dass das Ankerteil an einer Rückseite der Gipskartonplatte anliegt. Der Kippanker kann nun belastet und es kann ein Gegenstand am Gewindestab des Kippankers angebracht werden.For cavity fastening, the anchor part of the known tilting anchor is pivoted with respect to the threaded rod such that it is approximately in line with the threaded rod and the threaded rod lies in an interior of the U-shaped anchor part. In this state, the toggle anchor is passed through a hole in, for example, a plasterboard. As soon as the anchor part is completely led through the plasterboard, it swings due to gravity into a position transverse to the threaded rod. The toggle anchor on the threaded rod is pulled back so far that the anchor part lies against the back of the plasterboard. The tilt anchor can now be loaded and an object can be attached to the threaded rod of the tilt anchor.
Der Erfindung liegt die Aufgabe zu Grunde, einen Kippanker der vorstehend erläuterten Art so weiter zu bilden, dass sein Ankerteil nach Durchführung durch ein Loch schwerkraftunabhängig in eine Querstellung zum Gewindestab schwenkt.The invention is based on the object of further developing a tilting anchor of the type explained above in such a way that its anchor part swings into a transverse position to the threaded rod independently of gravity after being carried out through a hole.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Der erfindungsgemäße Kippanker weist ein Schraubenfederelement auf, in das der Gewindestab ein Stück weit eingeschraubt ist. Mit Abstand vom Gewindestab ist das Schrau- Ankerteil. Mit Schraubenfederelement ist ein Federelement gemeint, das einen wendel- förmigen Einschraubabschnitt aufweist, in den ein Ende des Gewindestabs eingeschraubt ist. Außerhalb des Einschraubabschnitts kann das Schraubenfederelement eine von der Wendelform abweichende, insbesondere zur Befestigung am Ankerteil geeignete Form aufweisen.This object is achieved by the features of claim 1. The tilting anchor according to the invention has a helical spring element into which the threaded rod is screwed in to a certain extent. At a distance from the threaded rod, the screw Anchor part. By helical spring element is meant a spring element which has a helical screw-in section into which one end of the threaded rod is screwed. Outside the screw-in section, the helical spring element can have a shape that deviates from the helix shape and is particularly suitable for attachment to the anchor part.
Das Ankerteil des erfindungsgemäßen Kippankers ist mit einem Gewindeloch versehen, dessen Achse in etwa quer zum Ankerteil verläuft und in welches der Gewindestab einschraubbar ist. Das Gewindeloch ist bei unverformtem Schraubenfederelement in etwa koaxial zum Schraubenfederelement oder genauer gesagt zu dessen Einschraubabschnitt im Ankerteil angeordnet. Zur Hohlraumbefestigung wird das Ankerteil gegen die Federkraft des Schraubenfederelements um etwa 90° so verschwenkt, dass es sich in etwa in einer Linie mit dem Gewindestab befindet. In dieser Stellung wird der Kippanker durch ein Loch beispielweise in einer Gipskartonplatte durchgeführt. Sobald das Ankerteil vollständig durch das Loch durchgetreten ist, schwenkt das Schraubenfederelement das Ankerteil zurück in die Ausgangsstellung, in der das Ankerteil in etwa quer zum Gewindestab steht. Dieses Schwenken des Ankerteils in die in etwa quer zum Gewindestab stehende Ausgangsstellung erfolgt durch die Federkraft des Schraubenfederelements und infolgedessen schwerkraftunabhängig oder auch gegen einen Schwerkrafteinfluss. Des Weiteren richtet das Schraubenfederelement das Ankerteil am Gewindestab so aus, dass das Gewindeloch des Ankerteils zumindest näherungsweise koaxial zum Gewindestab ausgerichtet ist. Der erfindungsgemäße Kippanker wird am Gewindestab zurückgezogen, bis das Ankerteil an einer Rückseite der Gipskartonplatte anliegt. Anschließend wird der Gewindestab in das Gewindeloch des Ankerteils eingeschraubt, das vom Schraubenfederelement zumindest in etwa koaxial zum Gewindestab ausgerichtet worden ist. Nach dem Einschrauben des Gewindestabs in das Gewindeloch kann ein Gegenstand am Gewindestab des Kippankers befestigt werden.The anchor part of the tilt anchor according to the invention is provided with a threaded hole, the axis of which extends approximately transversely to the anchor part and into which the threaded rod can be screwed. When the helical spring element is not deformed, the threaded hole is arranged approximately coaxially with the helical spring element or more precisely with its screw-in section in the anchor part. To fix the cavity, the anchor part is pivoted against the spring force of the coil spring element by approximately 90 ° so that it is approximately in line with the threaded rod. In this position, the tilt anchor is passed through a hole, for example in a plasterboard. As soon as the anchor part has completely passed through the hole, the helical spring element swivels the anchor part back into the starting position, in which the anchor part is approximately transverse to the threaded rod. This pivoting of the armature part into the initial position approximately transverse to the threaded rod is effected by the spring force of the helical spring element and, as a result, is independent of gravity or also against the influence of gravity. Furthermore, the helical spring element aligns the anchor part on the threaded rod such that the threaded hole of the anchor part is at least approximately coaxially aligned with the threaded rod. The tilt anchor according to the invention is pulled back on the threaded rod until the anchor part rests on a rear side of the plasterboard. The threaded rod is then screwed into the threaded hole of the anchor part, which has been aligned at least approximately coaxially with the threaded rod by the helical spring element. After screwing the threaded rod into the threaded hole, an object can be attached to the threaded rod of the tilt anchor.

A screw thread of the threaded rod 26 is suitable for an internal thread of the threaded hole 14, so that the threaded rod 26 can be screwed into the threaded hole 14 of the anchor part 12. A diameter of the helical spring element 18 in the screw-in section 20 is selected such that the threaded rod 26 can be screwed in.
Im Bereich der Federwindungen 22 und im Befestigungsabschnitt 24 weist das Schraubenfederelement 18 einen größeren Durch- bzw. Quermesser als im Einschraubabschnitt 20 auf, so dass der Gewindestab 26 durch das Schraubenfederelement 18 durchschraubbar ist, dabei allerdings nur mit dem Einschraubabschnitt 20 in Eingriff steht.In the area of the spring windings 22 and in the fastening section 24, the helical spring element 18 has a larger diameter or transverse diameter than in the screw-in section 20, so that the threaded rod 26 can be screwed through the helical spring element 18, but is only engaged with the screw-in section 20.
Eine mögliche Verwendung des erfindungsgemäßen Kippankers 10 ist in Figuren 3 und 4 dargestellt: Zur Befestigung des Kippankers 10 an beispielsweise einer Gipskartonplatte 30 wird diese mit einem Loch 32 durchbohrt. Ein Durchmesser des Lochs 32 ist so groß gewählt, dass das U-förmige Ankerteil 12 in Längsrichtung durchgesteckt werden kann. Zum Durchstecken des Ankerteils 12 wird der Gewindestab 26 wie in Figur 3 zu sehen um 90° zur Seite geschwenkt, so dass er in etwa in einer Linie mit dem Ankerteil 12 ausgerichtet ist und in dem U-förmigen Ankerteil 12 einliegt. Das Schwenken des Gewindestabs 26 in Bezug auf das Ankerteil 12 wird durch das Schraubenfederelement 32 in der Gipskartonplatte 30 durchgesteckt.A possible use of the tilt anchor 10 according to the invention is shown in FIGS. 3 and 4: To attach the tilt anchor 10 to, for example, a plasterboard board 30, this is drilled through with a hole 32. A diameter of the hole 32 is chosen so large that the U-shaped anchor part 12 can be pushed through in the longitudinal direction. To insert the anchor part 12, the threaded rod 26 is pivoted 90 ° to the side, as can be seen in FIG. 3, so that it is aligned approximately in a line with the anchor part 12 and lies in the U-shaped anchor part 12. The pivoting of the threaded rod 26 with respect to the anchor part 12 is done by the coil spring element 32 inserted in the plasterboard 30.
Das Ankerteil 12 wird vollständig durch das Loch 32 in der Gipskartonplatte 30 durchgesteckt, so dass das Ankerteil 12 auf einer Rückseite aus der Gipskartonplatte 30 austritt und von der Gipskartonplatte 30 frei kommt. Dabei wird das Ankerteil 12 am Gewindestab 26 gehalten, der durch die Gipskartonplatte 30 durchsteht. Eine Federkraft des Schraubenfederelements 18, das das Ankerteil 12 mit dem Gewindestab 26 verbindet, schwenkt das Ankerteil 12 zurück in die Ausgangslage, in der das Ankerteil 12 quer zum Gewindestab 26 steht und das Gewindeloch 14 des Ankerteils 12 koaxial zum Gewindestab 26 ist.The anchor part 12 is pushed completely through the hole 32 in the plasterboard plate 30, so that the anchor part 12 emerges from the plasterboard plate 30 on a rear side and comes free from the plasterboard plate 30. The anchor part 12 is held on the threaded rod 26 which protrudes through the plasterboard 30. A spring force of the helical spring element 18, which connects the anchor part 12 with the threaded rod 26, pivots the anchor part 12 back into the starting position, in which the anchor part 12 is transverse to the threaded rod 26 and the threaded hole 14 of the anchor part 12 is coaxial with the threaded rod 26.
Am Gewindestab 26 wird das Ankerteil 12 soweit zurückgezogen, bis es, wie in Figur 4 dargestellt, an der Rückseite der Gipskartonplatte 30 anliegt. Anschließend wird der Gewindestab 26 durch das Schraubenfederelement 18 durchgeschraubt und in das Gewindeloch 14 des Ankerteils 12 eingeschraubt. Da das Schraubenfederelement 18 den Gewindestab 26 koaxial zum Gewindeloch 14 des Ankerteils 12 ausrichtet gelangt der Gewindestab 26 beim Einschrauben problemlos in das Gewindeloch 14. Dabei hilft zusätzlich die Fase 28 des Gewindestabs 26, die den Gewindestab 26 beim Einschrauben in das Gewindeloch 14 am Gewindeloch 14 ausrichtet.The anchor part 12 is retracted on the threaded rod 26 until, as shown in FIG. 4, it rests on the back of the plasterboard 30. Then the threaded rod 26 is screwed through the coil spring element 18 and screwed into the threaded hole 14 of the anchor part 12. Since the helical spring element 18 aligns the threaded rod 26 coaxially with the threaded hole 14 of the anchor part 12, the threaded rod 26 easily passes into the threaded hole 14 when screwing in. In addition, the chamfer 28 of the threaded rod 26 helps, which the threaded rod 26 when screwed into the threaded hole 14 on the threaded hole 14 aligns.
Sobald der Gewindestab 26 in das Gewindeloch 14 des Ankerteils 12 eingeschraubt ist, kann eine Last an dem aus der Gipskartonplatte 30 vorstehenden Gewindestab 26 angebracht werden. As soon as the threaded rod 26 is screwed into the threaded hole 14 of the anchor part 12, a load can be attached to the threaded rod 26 protruding from the plasterboard 30.
