Bei der Ausführungsform nach Pig» 1 besteht der Schaft des schraubenartigen Befestigungselementes aus mehreren in Schaftlängsrichtung aufeinanderfolgenden koaxialen Abschnitten 3? die jeweils die Gfestalt eines Kegelstumpfes haben, aus einem zylindrischen Teil 4 an der dem Kopf 2 zugewandten Seite des Schaftes und aus einem die Spitze des gesamten Befestigungselementes darstellenden Kegel 5· Die kegelförmigen Abschnitte, von denen z.B. vier oder fünf vorgesehen sein können, verjüngen sich in Sichtung zur Spitze hin gemäß Pfeil 6 und können an der der SpitzeIn the embodiment according to Pig »1, there is the shaft of the screw-like fastening element made up of several coaxial ones that follow one another in the longitudinal direction of the shaft Sections 3? each the shape of a truncated cone have a cylindrical part 4 on the side of the shaft facing the head 2 and a tip of the entire fastening element representing cones 5 The conical sections, of which e.g. four or five can be provided, taper towards the tip according to arrow 6 and can be at the tip
abgewandten Seite jeweils annähernd widerhakenförmig ausgebildet sein. Zu diesem Zweck ist die Anordnung so getroffen, daß die Mantelflächen 7 der kegelstumpfförmigen Abschnitte des Schaftes jeweils einen Winkel öC von 15 bis 30° mit der axialen Richtung 6 bilden und parallel zueinander verlaufen und daß einerseits die großen Grundflächen 8 und andererseits die kleinen Grundflächen 9 der verschiedenen aufeinanderfolgenden kegelstumpfförmigen Abschnitte einander genau entsprechen· Der Durchmesser 10 der großen Grundflächen ist hierbei dem Durchmesser des zylindrischen Abschnittes 4 gleich· Die die einzelnen Abschnitte des Schaftes bildenden Kegel und Kegel— stümpfe haben als Leitlinie jeweils einen Kreis.facing away from each side approximately barb-shaped be trained. For this purpose, the arrangement is made so that the lateral surfaces 7 of the frustoconical Sections of the shaft each form an angle δC of 15 to 30 ° with the axial direction 6 and are parallel run to each other and that on the one hand the large base areas 8 and on the other hand the small base areas 9 of the different successive frustoconical Sections correspond exactly to each other · The diameter 10 of the large base areas is the diameter here of the cylindrical section 4 equal · The cones and cones forming the individual sections of the shaft - stumps each have a circle as a guideline.
Bei der Ausführungsform nach Fig. 1 hat der Kopf 2 die Gestalt eines sich zur Spitze hin verjüngenden Kegelstumpfes, dessen kleine Grundfläche 11 einen Durchmesser besitzt, der dem Durchmesser der zylindrischen Partie 4 und der großen Grundfläche der einzelnen kegelstumpfförmigen Abschnitte entspricht. Bei dieser Ausführungsform gemäß Fig. 1 besitzt der Kopf an seiner der Spitze abgekehrten Stirnfläche 13 einen Längsschlitz 12, der dazu dient, einem Schraubenzieher od.dgl» eine Angriffs— möglichkeit zu geben, wie dies bei Holzschrauben üblich ist« Im Hinblick auf die neue Gestalt des BefestigungselementesIn the embodiment according to FIG. 1, the head 2 has the shape of a truncated cone tapering towards the tip, the small base 11 of which has a diameter has, which corresponds to the diameter of the cylindrical part 4 and the large base area of the individual frustoconical sections. In this embodiment According to FIG. 1, the head has a longitudinal slot 12 on its end face 13 facing away from the tip, which serves to "attack" a screwdriver or the like possibility to give, as is usual with wood screws «With regard to the new shape of the fastening element
