Beschreibung description
Die Erfindung betrifft ein Werkzeug mit den Merkmalen des Oberbegriffs des Patentanspruchs 1. The invention relates to a tool with the features of the preamble of patent claim 1.
Das Einbringen von Schraubhülsen in ein Baumaterial erfolgt bisher mit Hilfe von allgemein bekannten Werkzeugen, deren Eingriffsmittel für den Eingriff mit verschiedenartigen Schlitzschrauben, Kreuzschlitzschrauben, Innensechskantschrauben o.dgl. ausgebildet sind. Dabei wird die Schraubhülse mit ihren an ihrem hinteren Ende vorgesehenen Gegeneingriffsmitteln auf das Werkzeug aufgesteckt und durch dieses selbstbohrend, beispielsweise in eine Gipsplatte, eingeschraubt. Diese Arbeitsweise erfordert einen exakt passenden Eingriff zwischen Werkzeug und Schraubhülse und ausserdem eine sorgfältige Handhabung, um zu vermeiden, dass die Schraubhülse beim Einschrauben durch seitlich wirkende Kraftkomponenten ihre Führung durch das Werkzeug verliert und von diesem abfällt. Ausserdem ist es arbeitsaufwendig, für das nachfolgende Einbringen einer Schraube in den Aufnahmekanal der Schraubhülse ein passendes zweites Werkzeug bereitzustellen und zu betätigen. The introduction of screw sleeves into a building material has so far been carried out with the aid of generally known tools, the engagement means for the engagement with different types of slotted screws, Phillips screws, hexagon socket screws or the like. are trained. The screw sleeve with its counter-engagement means provided at its rear end is pushed onto the tool and screwed through it self-drilling, for example into a plasterboard. This method of operation requires a precisely fitting engagement between the tool and the screw sleeve and, moreover, careful handling in order to prevent the screw sleeve from losing its guidance through the tool when it is screwed in due to laterally acting force components and falling off the tool. In addition, it is labor-intensive to provide and operate a suitable second tool for the subsequent insertion of a screw into the receiving channel of the screw sleeve.
Der Erfindung liegt die Aufgabe zugrunde, ein Werkzeug der eingangs genannten Art zu finden, das eine einfachere und zuverlässigere Arbeitsweise beim Befestigen von Gegenständen mittels selbstbohrenden Schraubhülsen und für diese vorgesehene Schrauben ermöglicht und das hierbei die Verwendung verschiedener Werkzeuge vermeidet. The invention has for its object to find a tool of the type mentioned, which enables a simpler and more reliable way of working when attaching objects by means of self-drilling screw sleeves and screws provided for them and which avoids the use of different tools.
Die Lösung dieser Aufgabe erfolgt erfindungsge-mäss aufgrund der kennzeichnenden Merkmale des Patentanspruchs 1. This object is achieved according to the invention on the basis of the characterizing features of patent claim 1.
Im folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert. Es zeigt: The invention is explained in more detail below with reference to an embodiment shown in the drawing. It shows:
Fig. 1 eine Seitenansicht eines erfindungsgemäs-sen Werkzeuges, 1 is a side view of a tool according to the invention,
Fig. 2 einen Längsschnitt durch eine zur Aufnahme einer Schraube vorgesehene Schraubhülse, mit ungeschnitten dargestellter Vorbohrspitze und Fig. 2 shows a longitudinal section through a screw sleeve provided for receiving a screw, with an uncut pre-drilling tip and
Fig. 3 eine Ansicht gegen das hintere Ende der Schraubhülse nach Fig. 2. 3 shows a view towards the rear end of the screw sleeve according to FIG. 2.
Das Werkzeug 1 entsprechend dem dargestellten Ausführungsbeispiel hat am hinteren Ende seines bolzenförmigen Körpers einen sechskantprofilierten Kupplungsteil 2 zur Herstellung eines formschlüssigen Eingriffs im Aufnahmefutter eines beispielsweise motorisch angetriebenen Drehschraubers. Die am sechskantförmig profilierten Kupplungsteil 2 vorgesehene umlaufende Ausnehmung 3 ermöglicht den Eingriff von im Aufnahmefutter vorgesehenen Haltemitteln. The tool 1 according to the illustrated embodiment has at the rear end of its bolt-shaped body a hexagonal profiled coupling part 2 for producing a positive engagement in the receiving chuck of a motor-driven screwdriver, for example. The circumferential recess 3 provided on the hexagonally profiled coupling part 2 enables the engagement of holding means provided in the receiving chuck.
Am vorderen Bereich des Werkzeuges 1 befinden sich in axialem Abstand voneinander kleinere und grössere Eingriffsmittel 4 und 5. Die die Werkzeugspitze bildenden vorderen Eingriffsmittel 4 sind für den Eingriff in eine nicht dargestellte Kreuzschlitzschraube ausgebildet, um diese als Befestigungsmittel in eine Schraubhülse 7 einzuschrauben. At the front area of the tool 1 there are smaller and larger engagement means 4 and 5 at an axial distance from one another. The front engagement means 4 forming the tool tip are designed for engagement in a Phillips screw, not shown, in order to screw it into a screw sleeve 7 as fastening means.
Die grösseren, hinteren Eingriffsmittel 5 sind für den Eingriff in die kreuzförmigen Schlitze 6 am hinteren Ende bzw. am Kopf 8 dieser Schraubhülse 7 bestimmt. The larger, rear engagement means 5 are intended for engagement in the cruciform slots 6 at the rear end or at the head 8 of this screw sleeve 7.
Der kurze Schaftteil des Werkzeuges, der zwischen beiden Eingriffsmitteln 4 und 5 vorgesehen ist, lässt sich so in den Aufnahmekanal 10 der Schraubhülse 7 einschieben, dass er zur Anlage an den in diesem vorgesehenen längsgerichteten Rippen 11 gelangt und somit einen Zentrierschaft 9 für die Schraubhülse 1 bildet. Auf diese Weise wird verhindert, dass sich die Schraubhülse 7 beim selbstbohrenden Einschrauben z.B. in eine Gipsplatte vom Werkzeug 1 durch Abkippen lösen kann. Eine nähere Beschreibung der Schraubhülse 7 ist der EP-A 0 575 295 zu entnehmen. The short shank part of the tool, which is provided between the two engagement means 4 and 5, can be inserted into the receiving channel 10 of the screw sleeve 7 in such a way that it comes to bear against the longitudinal ribs 11 provided therein and thus a centering shaft 9 for the screw sleeve 1 forms. In this way it is prevented that the screw sleeve 7 during self-drilling, e.g. in a plasterboard from tool 1 by tipping. A more detailed description of the screw sleeve 7 can be found in EP-A 0 575 295.
Es versteht sich, dass ein erfindungsgemässes Werkzeug, abweichend vom in der Zeichnung dargestellten Ausführungsbeispiel, angepasst an die Gestaltung der Schraubhülse, in zahlreichen Varianten ausgeführt sein kann. Z.B. sind unterschiedliche Ausführungen der Eingriffsmittel 4, 5 und verschiedene Querschnittsformen des Zentrierschaftes 9 möglich. It goes without saying that a tool according to the invention, deviating from the exemplary embodiment shown in the drawing and adapted to the design of the screw sleeve, can be implemented in numerous variants. E.g. Different designs of the engagement means 4, 5 and different cross-sectional shapes of the centering shaft 9 are possible.
