DübelDowels

Beschreibung:Description:

Die Erfindung betrifft einen Dübel zur Befestigung von Ge¬ genstanden an Bauteilen, insbesondere an Gipskartonbauplat- ten, mit einem aufspreizbaren Dubelkorper, der eine Innen¬ bohrung zum Eindrehen einer Befestigungsschraube aufweist.The invention relates to a dowel for fastening objects to components, in particular to plasterboard, with an expandable dowel body which has an inner bore for screwing in a fastening screw.

Die Erfindung betrifft weiterhin ein Verfahren zur Herstel¬ lung eines Dübels mit einer Innenbohrung und einem Innen¬ gewinde.The invention further relates to a method for the manufacture of a dowel with an internal bore and an internal thread.

Aus der DE 24 52 398 ist ein Dübel zur Befestigung von Ge¬ genstanden an Platten oder Hohlräume aufweisenden Bauteilen mit einer Innenbohrung zum Eindrehen einer Befestigungs¬ schraube bekannt, der auch für Gipskartonbauplatten geeignet sein soll. Der Dübel ist an seinem hinteren Ende durch einen Schlitz m zwei Teile geteilt und weist an seinem einfuhr- seitigen vorderen Ende beim Durchstecken des Dübels durch ein Bohrloch radial auffedernde, die Platte bzw. die Stirn¬ wand des Hohlraumes hintergreifende Flügel auf.From DE 24 52 398 a dowel for attaching objects to panels or cavities having components with an inner bore for screwing in a fastening screw is known, which is also said to be suitable for plasterboard panels. The dowel is divided into two parts at its rear end by a slot m and has at its front end on the insertion side, when the dowel is pushed through a borehole, radially resilient wings engaging behind the plate or the end wall of the cavity.

Dieser Dübel hat den Nachteil, daß zum Einstecken des Dübels m das Bohrloch die auffedernden Flügel vorher angelegt wer¬ den m ssen. Hierfür muß der Dübel beim Einstecken gleichzei¬ tig gedreht werden. Dies ist zum einen umständlich und zum anderen besteht die Gefahr, daß das Bohrloch beschädigt wird. Auch ist es praktisch nicht möglich, den Dübel wieder herauszuziehen. Er muß also zum Entfernen durch das Bohrloch nach innen durchgestoßen werden, was ebenfalls zu einer Be¬ schädigung des Bohrloches fuhrt. Weiter hat dieser Dübel, wie auch andere bekannte Dübel, den Nachteil, daß bei star- kerer Belastung bei Gipskartonbauplatten das Bohrloch nach hinten - zum zu befestigenden Gegenstand hin - ausbrechen kann. Weiterhin ist sein auffedernder Bereich relativ lang, so daß ein entsprechender tiefer Freiraum hinter der Platte benotigt wird. Wegen seiner Baulange ist der bekannte Dübel daher auch für Sackbohrungen wenig geeignet.This dowel has the disadvantage that to insert the dowel m the borehole must first be opened by the resilient wings. For this purpose, the plug must be rotated at the same time when it is inserted. On the one hand this is cumbersome and on the other hand there is a risk that the borehole will be damaged. It is also practically impossible to pull the dowel out again. It must therefore be pushed in through the borehole for removal, which likewise leads to damage to the borehole. Furthermore, this dowel, like other known dowels, has the disadvantage that the borehole can break out to the rear - towards the object to be fastened - when the plasterboard building boards are subjected to greater loads. Furthermore, its resilient area is relatively long, so that a corresponding deep space is required behind the plate. Because of its length, the well-known dowel is therefore also unsuitable for blind bores.

Aufgabe der vorliegenden Erfindung ist es daher, einen Dübel so zu verbessern, daß er hoch belastbar, leicht montierbar und auch wieder entfernbar ist. Auch soll der Dübel das ihn umgebende Bauteil nicht beschädigen und insbesondere auch für Gipskartonbauplatten geeignet sein.The object of the present invention is therefore to improve a dowel so that it is highly resilient, easy to assemble and also removable. The dowel should also not damage the component surrounding it and in particular should also be suitable for gypsum plasterboard.

Diese Aufgabe wird erfmdungsgemaß dadurch gelost, daß der Dubelkorper m einem emfuhrseitigen vorderen Bereich durch von einem vorderen Ende ausgehende Schlitze in mindestens zwei Kopfsegmente aufgeteilt ist und in dem vorderen Bereich an seiner Mantelflache eine umlaufende Einschnürung aufweist und daß der Dubelkorper an seinem dem vorderen Ende abge¬ wandten hinteren Ende eine quer zu einer Dubellangsachse verlaufende Anschlagplatte aufweist.This object is achieved according to the invention in that the dubble body is divided into at least two head segments in an upstream front area by slots emanating from a front end and has a circumferential constriction in the front area on its lateral surface and in that the dubble body at its front end ¬ turned rear end has a stop plate extending transversely to a double longitudinal axis.

Dieser Dübel hat den Vorteil, daß er einfach zu montieren ist, da seine Kopfsegmente erst aufspreizen und das Bauteil sozusagen als Zahne hintergreifen, wenn die Befestigungs¬ schraube in eine gewisse Tiefe eingedreht wird. Nach min¬ destens teilweisem Herausschrauben der Befestigungsschraube kann der Dübel wieder aus dem Bohrloch entfernt werden, ohne das Bohrloch zu beschädigen. Durch die Anschlagplatte wird vorteilhaft erreicht, daß Kräfte m die Anschlagplatte abge¬ leitet werden und trotz hoher Belastung das Bohrloch nicht ausbricht. Die KopfSegmente können zudem, wie auch der ge- samte Dübel, eine relativ kurze Baulange aufweisen. Dieser Dübel ist daher auch ohne Schwierigkeiten in Sackbohrungen und somit universell einsetzbar.This dowel has the advantage that it is easy to assemble, since its head segments only spread open and, as it were, reach behind the component as a tooth when the fastening screw is screwed in to a certain depth. After at least partially unscrewing the fastening screw, the dowel can be removed from the borehole again without damaging the borehole. The stop plate advantageously ensures that forces are derived from the stop plate and that the borehole does not break out despite high loads. The head segments, like the entire dowel, can also have a relatively short overall length. This dowel can therefore be used in blind holes without difficulty and can therefore be used universally.

In einer weiteren vorteilhaften Ausgestaltung weist der Du- belkorper an seiner Innenbohrung eine vor der Anschlagplätte liegende Aussparung auf, in der ein Einsatz mit einem Gewin¬ de angeordnet ist. Durch den Einsatz kann in Verbindung mit einer Metallschraube eine besonders hohe Belastbarkeit in achsialer Richtung und auch in radialer Richtung erreicht werden.In a further advantageous embodiment, the dowel body has on its inner bore a recess lying in front of the stop plate, in which an insert with a thread is arranged. By using it in conjunction with a metal screw, a particularly high load capacity in the axial direction and also in the radial direction can be achieved.

Weitere Aufgabe der Erfindung ist es, ein Verfahren zur Her¬ stellung eines Dübels mit einer Innenbohrung und einem In¬ nengewinde zu finden, mit dem ein solcher Dübel auf einfache Weise herstellbar ist.Another object of the invention is to find a method for producing a dowel with an inner bore and an inner thread, with which such a dowel can be produced in a simple manner.

Diese Aufgabe wird erfmdungsgemaß dadurch gelost, daß der Dübel aus zwei vertikalen Hälften mit einer Aussparung für einen Einsatz mit dem Innengewinde gefertigt wird, wobei m die erste Hälfte der Einsatz eingesetzt und die zweite Hälf¬ te mit der ersten Hälfte verbunden wird.This object is achieved according to the invention in that the dowel is manufactured from two vertical halves with a recess for use with the internal thread, the first half of the insert being inserted and the second half being connected to the first half.

Durch das erfmdungsgemaße Verfahren kann der Dubelkorper im Spritzgußverfahren - vorzugsweise aus Kunststoff - herge¬ stellt werden, ohne in den Dübel ein Gewinde schneiden zu müssen. Auch ist es nicht notwendig, vor dem Spritzen den Einsatz in die Spritzform einbringen zu müssen. Durch die Ausbildung des Dubelkorpers in zwei Hälften, ist ein beson¬ ders einfaches Einsetzen des Einsatzes möglich.By means of the method according to the invention, the dowel body can be produced by injection molding, preferably from plastic, without having to cut a thread in the dowel. It is also not necessary to insert the insert into the injection mold before spraying. The design of the dowel body in two halves makes it particularly easy to insert the insert.

Gemäß einer vorteilha ten Ausgestaltung sind die beiden Hälften des Dubelkorpers an einer Längsseite so miteinander verbunden, daß sie mit der Verbindungsstelle als Drehpunkt nach dem Einsetzen des Einsatzes einfach zusammengeklappt werden können und beispielsweise durch einen über den Dubel¬ korper uberzuschiebenden Ring gesichert werden.According to an advantageous embodiment, the two halves of the dowel body are connected to one another on one long side in such a way that they can simply be folded together with the connection point as the fulcrum after insertion of the insert and are secured, for example, by a ring to be pushed over the dubble body.

Weitere Einzelheiten der Erfindung ergeben sich aus der nachfolgenden ausfuhrlichen Beschreibung und den beigefugter Zeichnungen, in denen bevorzugte Ausfuhrungsformen der Er¬ findung beispielsweise veranschaulicht sind.Further details of the invention result from the following detailed description and the attached drawings, in which preferred embodiments of the invention are illustrated, for example.

Em Dübel besteht aus einem Dubelkorper (1,1', l'') und emeir Einsatz (2) mit Gewinde. Der Dubelkorper (1,1',1' weist einen emfuhrseitigen vorderen Bereich (3) mit einem vorde¬ ren Ende (4) auf. Durch vom vorderen Ende (4) ausgehende Schlitze (5, 5', 5'') wird der vordere Bereich (3) in Kopf- segmente (6, 6', 6'') aufgeteilt. In dem vorderen Bereich (3) des Dubelkorpers (1, 1 ' , 1 ' ' ) ist eine kegelstumpf- formige Einschnürung (7) angeordnet. Durch die Einschnü¬ rung (7) bilden die Kopfsegmente (6, 6', 6'') eine Art Zahne, die mit ihrer planen - dem vorderen Ende (4) abgewandten - Flache (8) das den Dubelkorper (1,1',1' * umgebende, zum Beispiel als Gipskartonbauplatte (10/ ausge¬ bildete Bauteil (9) hintergreifen können. Es ist aber auch möglich, den Dübel in einem Bauteil (9') mit einer Sackboh- rung (11) zu verwenden. Hierbei werden die Kopfsegmente (6, 6',6'') unter Verformung durch die Befestigungsschraube (17 ■ gegen die Wand der Sackbohrung (11) gepreßt, so daß der Du¬ belkorper (1,1' ,1'') einen Festsitz im Bauteil (9') erhalt.An anchor consists of a dowel body (1,1 ', l'') and an insert (2) with thread. The dowel body (1, 1 ', 1' has a front area (3) on the discharge side with a front end (4). The slots (5, 5 ', 5'') extending from the front end (4) The front area (3) is divided into head segments (6, 6 ', 6 "). A cone-shaped constriction (7) is arranged in the front area (3) of the dowel body (1, 1', 1") Due to the constriction (7), the head segments (6, 6 ', 6'') form a type of tooth which, with its flat surface (8) facing away from the front end (4), the dubbing body (1,1 ', 1' * surrounding, for example as a gypsum plasterboard (10 / trained component (9). It is also possible to fix the dowel in one component (9 ') with a sack board tion (11) to use. Here, the head segments (6, 6 ', 6'') with deformation are pressed by the fastening screw (17 ■ against the wall of the blind bore (11), so that the Du¬ belkorper (1,1', 1 '') is an interference fit in the component (9 ').

An seinem dem vorderen Ende (4) abgewandten hinteren Ende (12) weist der Dubelkorper (1,1',1'') eine Anschlagplatte (13, 13" , 13' ' ) auf, die gegen das Bauteil (9, 9', '') an¬ schlagt. Die Anschlagplatte (13,13') weist zwei parallele Abflachungen (14) auf, deren Abstand etwa dem Durchmesser des in ein Bohrloch (18, 18') eines Bauteiles (9, 9', 9'') einzuführenden Teils des Dubelkorpers (1,1') entspricht. Dies hat zum einen den Vorteil, daß der Dubelkorper aus zwei miteinander verbundenen zusammenklappbaren Hälften (15,16) zusammengefugt werden kann und zum anderen kann der Dubel¬ korper (1,1') bei der Montage an der Anschlagplatte (13,13') mit einem Maulschlüssel fixiert werden.At its rear end (12), which faces away from the front end (4), the dowel body (1, 1 ', 1' ') has a stop plate (13, 13 ", 13' ') which bears against the component (9, 9' The stop plate (13, 13 ') has two parallel flats (14), the spacing of which is approximately the diameter of a component (9, 9', 9 'into a borehole (18, 18') This has the advantage, on the one hand, that the dubble body can be assembled from two collapsible halves (15, 16) connected to one another and, on the other hand, the dubble body (1,1 ') can be fixed with an open-end wrench when mounting on the stop plate (13, 13').

Der Dubelkorper weist eine Innenbohrung (19,19'') auf, die sich an ihrem dem vorderen Bereich (3) zugewandten vorderen Ende hm ver ungt bzw. verschließt. So kann das vordere Ende der Innenbohrung (19,19') kegelstumpfformig oder auch halb- kugelformig ausgebildet sein. Im Anschluß an die Innenboh¬ rung (19,19') können aber auch zwei quer zur Dubellangsachse (21) verlaufende Querbohrungen (22) als vorderes Ende der Innenbohrung (19,19') angeordnet sein. Durch Einschrauben einer Befestigungsschraube (17) wird das vordere Ende der Innenbohrung (19,19') auseinander gedruckt, so daß sich der Dubelkorper (1,1',1'') seinem vorderen Bereich (3/ auf- spreizt. Die Innenbohrung (19,19') kann mit einem Gewinde hergestellt werden oder das Gewinde bei der Montage des D ¬ bels durch eine als selbstschneidende Schraube ausgebildete Befestigungsschraube (17) erzeugt werden. Vorzugsweise weist die Innenbohrung eine Aussparung (20) auf, in der eir Einsatz mit Gewinde, zum Beispiel eine Sechskantmutter, an¬ geordnet ist. Dadurch wird die Festigkeit gegen Ausreißen der Befestigungsschraube (l' erhöht und die Befestigunq≤- schraube (17) kann als eine leichtgangige Schraube ausge¬ bildet sein, die em Maschinengewinde - zum Beispiel em übliches metrisches Gewinde - aufweist. Die Befestigungs¬ schraube (17) ist an ihrem vorderen Ende mit einer kege- ligen Spitze zum leichteren Durchdringen des vorderen Be¬ reiches (3) des Dubelkorpers (1,1',1'') versehen.The Dubelkorper has an inner bore (19, 19 ''), which closes or closes at its front end (3) facing the front end. For example, the front end of the inner bore (19, 19 ') can be frustoconical or hemispherical. Following the inner bore (19, 19 '), however, two transverse bores (22) extending transversely to the double longitudinal axis (21) can also be arranged as the front end of the inner bore (19, 19'). The front end of the inner bore (19, 19 ') is pressed apart by screwing in a fastening screw (17), so that the dowel body (1,1', 1 '') expands its front area (3 /. 19, 19 ') can be produced with a thread or the thread can be produced during assembly of the dowel by means of a fastening screw (17) which is designed as a self-tapping screw Thread, for example a hexagon nut, is arranged. This increases the strength against tearing out the fastening screw (1 ' and the fastening Screw (17) can be designed as a smooth-running screw which has a machine thread - for example a conventional metric thread. The fastening screw (17) is provided at its front end with a conical tip for easier penetration of the front area (3) of the dowel body (1, 1 ', 1'').
