Description
Holzschraube. Gegenstand vorliegender Erfindung ist eine Holzschraube mit Versenkkopff welcher mit einem Schneidwerk ausgestattet ist, das beim Einführen der Schraube- in das Holz aus diesem eine Vertiefung herausarbeitet, in die der Schraubenkopf zu liegen kommt.
Auf der beiliegenden Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstan des dargestellt und zwar zeigt: Fig. 1 eine Längsansicht desselben, Fig. 2 eine Endansicht von der Spitze des Schraubenbolzens her gesehen; Fig. 3 einen Schnitt durch den Schrauben kopf nach der Linie A-A der Fig. 1.
a bezeichnet einen Schraubenschaft mit dem Versenkkopf b. Dieser besitzt auf der in die Versenkung einzuführenden untern Seite vier vom Schraubenschaft aus nach aussen gehende Nuten c. Die eine Kante einer jeden Nute ist leicht erhöht und als Schneide d ausgebildet. Mittelst den Schneiden d wird beim Einführen der Schraube in das Holz aus diesem eine Versenkung herausge arbeitet, in welche der Schraubenkopf b zu liegen kommt. Die Schneiden d reichen nicht ganz bis an den Umfang des Schraubenkopfes b heran. Damit wird bezweckt, dass die vom Schneidwerk ausgefräste =Vertiefung nicht zu gross ausfällt.
Wood screw. The subject of the present invention is a wood screw with a countersunk head which is equipped with a cutting mechanism which, when the screw is inserted into the wood, creates a recess in which the screw head comes to rest.
In the accompanying drawing, an embodiment of the subject invention is shown, namely: Figure 1 is a longitudinal view of the same, Figure 2 is an end view seen from the tip of the screw bolt; Fig. 3 is a section through the screw head along the line A-A of FIG.
a denotes a screw shaft with countersunk head b. This has on the lower side to be inserted into the countersink four grooves c extending outwards from the screw shaft. One edge of each groove is slightly raised and designed as a cutting edge d. By means of the cutting edges d, when the screw is inserted into the wood, a countersink is made out of this, in which the screw head b comes to rest. The cutting edges d do not quite reach the circumference of the screw head b. The purpose of this is to ensure that the recess milled out by the cutting unit is not too large.
