KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bekannt sind aus Blech gestanzte Dübel, in deren einteiligen Schaft ein Schraubengewinde eingepreßt ist. Demgegenüber ist Gegenstand der Erfindung ein Dübel, der aus zwei Blechhälften mit umgebördelten Rändern der Länge nach zusammengesetzt ist. Die Dübelteile erhalten schon vor ihrer Zusammensetzung ihre endgültige Gestalt als spitz zulaufende Hülsenhälften, in die gleichfalls ein Schraubengewinde eingepreßt ist, mittels dessen der Dübel in ihm eingeführte Schrauben oder Holzpflöcke sicher festhält.Dowels punched from sheet metal are known, in the one-piece shaft of which there is a screw thread is pressed in. In contrast, the subject of the invention is a dowel, which consists of two Sheet metal halves with beaded edges is assembled lengthwise. The dowel parts receive their final shape as a tapering one even before they are assembled Sleeve halves, in which a screw thread is also pressed, by means of which the dowel securely holds screws or wooden pegs inserted in it.
Die Zeichnung veranschaulicht die Neuerung, und zwar zeigen:The drawing illustrates the innovation, namely show:
Fig. ι und 2 den Dübel in Seitenansicht und Querschnitt mit eingetriebenem Holzpflock, um ihn für Holzschrauben verschiedener Größe brauchbar zu machen, ; Fig. Ι and 2 the dowel in side view and cross-section with driven wooden peg to make it useful for wood screws of different sizes ;
Fig. 3 und 4 den Dübel mit in das eingepreßte Gewinde unmittelbar eingeführter Schraube.3 and 4 the dowel with the screw directly inserted into the pressed-in thread.
Die beiden Teile α und b, aus denen der Dübel zusammengesetzt ist, entsprechen je einer Dübelhälfte und besitzen Flanschen d und e, von denen die der einen Dübelhälfte breiter gehalten sind als die der andern, so daß beim Zusammensetzen die breiten über die schmäleren umgebördelt werden können und so dem fertigen Dübel eine gegen Stauchung beim Einschlagen in die Mauer genügende Widerstandsfähigkeit geben. Die Zweiteilung des Dübels in der Längsachse gestattet es, den Dübelhälften vor dem Zusammensetzen durch Pressung ihre endgültige, bei c spitz zulaufende Hohlform zu geben und die Gewinderillen auf dem Umfange einzudrücken.The two parts α and b, from which the dowel is composed, each correspond to a dowel half and have flanges d and e, of which the one half of the dowel is kept wider than the other, so that when assembling the wide ones are flanged over the narrower ones and thus give the finished dowel sufficient resistance to compression when hammering into the wall. The division of the dowel in two in the longitudinal axis allows the dowel halves to be given their final hollow shape, tapering to a point at c, before they are assembled, and the thread grooves to be pressed in on the circumference.
