SpreizdübelExpansion anchor

Die Neuerung betrifft einen Spreizdübel zur Befestigung von Gegenständen an Wänden, Decken u. dgl«The innovation concerns an expansion dowel for attaching objects to walls, ceilings and the like «

Es ist bereits bekannt, Gegenstände an Wänden mittels Dübeln zu befestigen« Abgesehen von einfachen Holzkeilen sind insbesondere aus profilierten Metallblechen bestehende und eine Fasermaterialfüllung aufweisende Dübel bekannt. Diese Dübel besitzen zwei an ihrem unteren Ende verbundene Blechstreifen, so daß zwischen dem Kopf und dem unteren Ende zwei parallele Längsschlitze gebildet sind. Durch die in die Faserfüllung eingedrehte Holzschraube wird bei diesen Dübeln im wesentlichen die Mitte des Dübels ausgebaucht und mit dem umgebenden Mauerwerk verankert. Der hintere im vollen Mauerwerk liegende.-Dübelteil wird somit nur wenig zur Verankerung ausgenutzt. Ferner kommt es oft vor, daß bei diesen Dübeln die Schraube seitlich aus dem Schlitz des Dübels austritt und nur ein fester Halt vorgetäuscht wird.It is already known to fasten objects to walls with dowels «apart from simple wooden wedges are in particular dowels consisting of profiled sheet metal and having a fiber material filling known. These dowels have two metal strips connected at their lower end, so that between the head and two parallel longitudinal slots are formed at the lower end. Through the wood screw screwed into the fiber filling With these dowels, the center of the dowel is essentially bulged and anchored to the surrounding masonry. The rear dowel part lying in the full masonry is therefore only little used for anchoring. Further it often happens that with these dowels the screw emerges laterally from the slot of the dowel and only one a firm hold is simulated.

Während bei der Herstellung von Mauerwerkslöchern mit Hammer und Meißel ein sich konisch mit der Lochtiefe verengender Querschnitt kaum vermieden werden kann, sind die mit motorgetriebenen Schlagbohrgeräten ausgeräumten Löcher von weitgehend zylindrischer Gestalt. Dadurch tragen auch andere, zum Ende konisch zulaufende Dübel nur auf einem kleinen Teil ihrer Mantelfläche und insbesondere nicht mit dem am tiefsten im Mauerwerk befindlichen Endteil.While in the manufacture of masonry holes with Hammer and chisel a cross-section that narrows conically with the depth of the hole can hardly be avoided the holes of a largely cylindrical shape that were cleared out with motorized percussion drills. Wear through it also other dowels tapering towards the end only on a small part of their lateral surface and in particular not with the end part that is deepest in the masonry.

Die Neuerung stellt sich die Aufgabe, einen auch in zylindrischen Löchern auf der ganzen Länge tragenden Dübel zu schaffen, bei dem die Schraube sicher in der Dübelmitte geführt wird. Dies wird nach der Neuerung dadurch erreicht, daß der Dübel einen oberen, ringförmig geschlossenen Einschraubteil aufweist, der in einen unteren überkreuz geschlitzten Dübelteil konstanten Außendurchmessers übergeht, in dem eine sich nach hinten konisch verengende Bohrung verläuft. In vorteilhafter Weiterbildung ist der untere Teil des Dübels aus einzelnen Backen gebildet, die gelenkig in den oberen Teil eingehängt sind, so daß sich die Backen unter der Wirkung der in die konisch verengte " ""-' Bohrung eindringenden Schraube nach außen spreizen können.The innovation has the task of creating a dowel that can also be used in cylindrical holes along the entire length, in which the screw is safely guided in the middle of the dowel. According to the innovation, this is achieved in that the dowel has an upper, annularly closed screw-in part which merges into a lower cross-slotted dowel part of constant outer diameter, in which a bore which tapers conically towards the rear runs. In an advantageous further development, the lower part of the dowel is formed from individual jaws which are hinged in the upper part so that the jaws can spread outward under the action of the screw penetrating the conically narrowed """-'hole.

Zum Einsetzen wird zweckmäßig der untere Teil des Dübels mit einem Gummiband od.dgl. zusammengehalten, damit die im oberenFor insertion, the lower part of the dowel is expediently with a rubber band or the like. held together so that the in the upper

Teil beweglich eingehängten Backen nicht aufklappen» Als Schrauben werden gewöhnliche Metallschrauben, gegebenenfalls mit vorn etwas krmisc-h, zulaufendem Gewinde benutzt. Die in den Dübeloberteil eingedrehte Schraube wird in dem Gewinde des Oberteils geführt, so daß sie mit Sicherheit zentral zwischen die vier Backen einläuft. Beim Eindrehen der Schraube tritt eine gegen das hintere Ende des Dübels zunehmende Spreizung der Backen ein, und die im Ruhezustand konische Bohrung nimmt eine zylindrische Form an, so daß die Innenflächen der Backen voll auf den Gewindegängen der Schraube tragend anliegen.Do not open the partially movably attached jaws. »Ordinary metal screws are used as screws, if necessary used with a slightly curved, tapering thread at the front. The screw screwed into the upper part of the dowel is guided in the thread of the upper part, so that it is safe runs centrally between the four jaws. When the screw is screwed in, one kicks against the rear end of the dowel increasing spreading of the jaws, and the conical bore in the rest state assumes a cylindrical shape, so that the inner surfaces of the jaws are fully supported on the threads of the screw.

Nachfolgend wird die Neuerung anhand der Darstellung zweier Ausführungsbeispiele in den beigefügten Zeichnungen näher erläutert. Es zeigen?The innovation is explained in more detail below with the aid of the representation of two exemplary embodiments in the accompanying drawings explained. Show it?

Fig. 5 einen Schnitt durch den Dübel der Fig. 3 in Höhe der Linie A-A.5 shows a section through the dowel of FIG. 3 in Height of line A-A.

Gemäß den Fig. 1 und 2 ist ein Dübel aus einem Oberteil 1 und einem geschlitzten Teil 2 aufgebaut. Im Anlieferungszustand bildet die äußere Mantelfläche des Dübels einen geraden Zylinder. Zentrisch im Oberteil ist ein Loch 4 für die einzusetzende Holzschraube 3 angeordnet, welches im geschlitzten Teil sich nach dem Ende konisch nach hinten verengend verläuft.According to FIGS. 1 and 2, a dowel is made from an upper part 1 and a slotted part 2 constructed. In the delivery condition, the outer surface of the anchor forms a straight cylinder. Centered in the upper part is a hole 4 for the wood screw 3 to be used, which is slotted in the Part tapers conically towards the rear after the end.

Durch das Eindringen der Schraube wird der geschlitzte Teil so auseinandergespreizt, daß die Wandungen des Loches 4 voll tragend auf dem Schraubengewinde aufliegen und die maximale Spreizung am -Dübelende eintritt. Dadurch wird eine gute Verankerung des Dübels im vollen Mauerwerk erreicht.By penetrating the screw, the slotted part is spread apart so that the walls of the hole 4 fully load-bearing on the screw thread and the maximum expansion occurs at the dowel end. This creates a good anchoring of the anchor in the full masonry is achieved.

An einem Oberteil 6 ist gemäß Fig. 3 eine ringförmige Ausnehmung 10 vorhanden, in der Lagerzapfen 7 der einzelnen Backen £ eingehängt sind. Durch ein um die Backen 2 geschlungenes Gummiband werden die Lagerzapfen 7 gegen das Herausfallen aus der Ausnehmung 10 gesichert. Die einzelnen Backen B bilden zwischen sich einen sich nach unten verjüngenden zylindrischen Kanal, in den beim Befestigen eine Schraubet eindringt. Der größere Durchmesser dieses. Kanals entspricht etwa dem Gewindedurchmesser der zu dem Dübel gehörigen Schraube 5«According to FIG. 3, an annular recess 10 is present on an upper part 6, in which the bearing journals 7 of the individual jaws £ are suspended. The bearing pins 7 are secured against falling out of the recess 10 by a rubber band looped around the jaws 2. The individual jaws B form between them a downwardly tapering cylindrical channel into which a screw penetrates when fastening. The larger diameter of this. Channel corresponds roughly to the thread diameter of the screw 5 «belonging to the dowel

In dem Oberteil 6 befindet sich ein zentrales Gewindeloch 11, in das die Schraube 5 eingeschraubt wird» Die Schraube 5 wird dadurch zentral geführt und treibt die Backen Ö gleichmäßig ..auseinander =In the upper part 6 there is a central threaded hole 11, into which the screw 5 is screwed down "The screw 5 is thereby guided centrally and drives the jaws east uniformly ..auseinander =

Gemäß Fig= 4 ist an dem oberen Ende jeder Backe ein Lagerzapfen 7 und ein Steg 12 ausgeformt^ der die Verbindung der Backe Ö mit dem Lagerzapfen 7 herstellt» Auf der Innenseite der Backe Ö ist ein zu der Schraube passendes Gewinde 9 angeordnet. Die Dübelteile können sowohl aus Kunststoff als auch aus Metall bestehen.According to FIG. 4, a bearing pin 7 and a web 12 are formed at the upper end of each jaw, which connects the jaw with the bearing pin 7. On the inside of the jaw there is a thread 9 that matches the screw. The dowel parts can be made of both plastic and metal.

In dem Querschnitt der Pig. 5 ist die Lage der Backen U, Öf bei eingesetzter Schraube 5 dargestellt,,In the cross section of the Pig. 5 shows the position of the jaws U, Ö f with inserted screw 5,

Beim Eindrehen der Schraube 5 in den Dübel wird diese zunächst in dem Gewinde 11 des Oberteils 6 geführt und tritt zentral zwischen die Backen B ein» Infolge des sich längs der Backen konisch verengenden Gewindeloches treibt die Schraube 5 beim weiteren Eindrehen in den Dübel die Backen Ö zunehmend auseinander, so daß die Backen schließlich auf ihrer ganzen Länge tragend auf dem Gewinde der Schraube aufliegen»When screwing the screw 5 into the dowel, it is first guided in the thread 11 of the upper part 6 and enters centrally between the jaws B. As a result of the tapered threaded hole along the jaws, the screw 5 drives the jaws Ö as it continues to be screwed into the dowel increasingly apart, so that the jaws finally rest on the screw thread over their entire length »
