Hülsenförmiger Spreizdübel
EMI1.1
verlängert und nach innen umgebogen, so dass sie sich gegen die Stirnfläche des Spreizkörpers legen.
In der Zeichnung sind einige Ausführungsbeispiele der Erfindung dargestellt. Es zeigt Fig. 1 einen Dübel für eine Maschinenschraube, Fig. 2 einen Dübel für eine Holzschraube, Fig. 3 einen Spreizkörper mit metrischem o. der Withworth-Gewinde, Fig. 4 einen Spreizkörper mit einem Muttergewinde für eine Holzschraube, Fig. 5 den Spreizkörper nach Fig. 3 in der Draufsicht, Fig. 6 die Anordnung der Führungsrippen an der Spreizhülse, und Fig. 7 einen Schnitt nach der Linie A-B in Fig. 6.
Der Dübel gemäss Fig. 1 besteht aus der Spreizhülse 4 und dem Spreizkörper 2. Der Spreizkörper 2 ist mit einem Muttergewinde für einen Schraubenbolzen 1 ausgebildet. Die Spreizhülse 4 und der Spreizkörper 2 sind aus einem zähen, harten und alterungsbeständigen Kunststoff hergestellt. Damit sich der Spreizkörper 2 beim Ansetzen der Befestigungsschraube nicht mitdrehen kann, ist er mit äusseren Längsnuten 3, 3'versehen, in die auf der Innenseite der Spreizhülse 4 angebrachte Rippen 5, 5'eingreifen. Nach dem Einsetzen des Spreizkörpers 2 in die Spreizhülse 4 wird der über die Stirnfläche des Spreizkörpers hinausragende Teil der Rippen 5, 5'auf thermischem Wege nach innen umgebogen.
Soll ein Gegenstand mit Holzschrauben an Mauerwerk, Beton od. dgl. befestigt werden, so wird der Spreizkörper 2 mit einem Muttergewinde 9 für Holzschrauben ausgebildet. Die Fig. 2 zeigt einen Dübel mit einer teilweise in das Gewinde 9 des Spreizkörpers 2 eingeschraubten Holzschraube 10.
Die Spreizhülse 4 ist mit inneren Längsschlitzen 6 versehen, die das Auseinanderspreizen der Hülse beim Anziehen der Befestigungsschraube erleichtern. Damit der in ein Mauerloch eingesetzte Dübel 1 bereits einen gewissen Halt gegen Verdrehen hat, be-
<Desc/Clms Page number 2>
vor die Befestigungsschraube angezogen wird, sind am Ende der Hülse keilförmige Rippen 8 angeordnet, die sich beim Einschieben des Dübels im Mauerloch verklemmen.
PATENTANSPRÜCHE :
1. Hülsenförmiger Spreizdübel mit einem konischen Spreizkörper, der in der Dübelhülse durch Eindrehen einer Schraube in Längsrichtung verschiebbar ist, dadurch gekennzeichnet, dass der Spreizkörper (2) aus zähem, hartem und alterungsbeständigem Kunststoff hergestellt ist und seine konische Umfangsfläche der konischen Innenfläche der in bekannter Weise aus Kunststoff hergestellten Spreizhülse (4) entspricht.

extended and bent inwards so that they lie against the face of the expansion body.
Some embodiments of the invention are shown in the drawing. 1 shows a dowel for a machine screw, FIG. 2 shows a dowel for a wood screw, FIG. 3 shows an expansion body with a metric or Withworth thread, FIG. 4 shows an expansion body with a nut thread for a wood screw, FIG The expansion body according to FIG. 3 in a top view, FIG. 6 the arrangement of the guide ribs on the expansion sleeve, and FIG. 7 a section along the line AB in FIG. 6.
The dowel according to FIG. 1 consists of the expansion sleeve 4 and the expansion body 2. The expansion body 2 is designed with a nut thread for a screw bolt 1. The expansion sleeve 4 and the expansion body 2 are made of a tough, hard and aging-resistant plastic. So that the expansion body 2 cannot rotate when the fastening screw is applied, it is provided with outer longitudinal grooves 3, 3 ′ into which ribs 5, 5 ′ attached to the inside of the expansion sleeve 4 engage. After the expansion body 2 has been inserted into the expansion sleeve 4, the part of the ribs 5, 5 ′ that protrudes beyond the end face of the expansion body is thermally bent inward.
If an object is to be fastened to masonry, concrete or the like with wood screws, the expansion body 2 is designed with a nut thread 9 for wood screws. 2 shows a dowel with a wood screw 10 partially screwed into the thread 9 of the expansion body 2.
The expansion sleeve 4 is provided with inner longitudinal slots 6, which facilitate the expansion of the sleeve when the fastening screw is tightened. So that the dowel 1 inserted into a hole in the wall already has a certain hold against twisting,
<Desc / Clms Page number 2>
before the fastening screw is tightened, wedge-shaped ribs 8 are arranged at the end of the sleeve, which jam in the wall hole when the dowel is inserted.
PATENT CLAIMS:
1. Sleeve-shaped expansion dowel with a conical expansion body which is displaceable in the dowel sleeve by screwing in a screw in the longitudinal direction, characterized in that the expansion body (2) is made of tough, hard and aging-resistant plastic and its conical peripheral surface of the conical inner surface of the known Way made of plastic expansion sleeve (4) corresponds.
