1. Gebiet der Erfindung 1. Field of the invention
Die vorliegende Erfindung betrifft eine Schraube, insbesondere eine verbesserte Schraube, die einen Schaft, einen an einem ersten Ende dieses Schaftes ausgebildeten Kopf, eine an einem zweiten Ende dieses Schafts ausgebildete Spitze sowie ein in einem äußeren ümfangsbereich des Schafts ausgebildetes Gewindeteil aufweist, wobei dieses Gewindeteil mehrere Schneidzähne umfaßt.The present invention relates to a screw, in particular to an improved screw, which has a shaft, a head formed at a first end of this shaft, a tip formed at a second end of this shaft and a threaded part formed in an outer peripheral region of the shaft, this threaded part comprising a plurality of cutting teeth.
2. Kurzbeschreibung des Standes der Technik 2. Brief description of the state of the art
Herkömmliche Schrauben bestehen aus einem Schaft und einem an einem Ende dieses Schaftes ausgebildeten Kopf, wobei das andere Ende des Schafts als steil zulaufende Spitze ausgebildet ist, um das Eindringen dieses Endes in den zur Aufnahme der Schraube vorgesehenen Gegenstand zu erleichtern. Der Schaft weist zudem ein in einem äußeren Ümfangsbereich ausgebildetes Gewindeteil auf, das beim Eindrehen der Schraube in den betreffenden Gegenstand . engen Eingriff mit dem Material dieses Gegenstandes eingeht, wodurch der Vorwärtsbewegung der Schraube innerhalb dieses Gegenstandes ein Widerstand entgegengesetzt wird. Hierdurch erhöht sich der Kraftaufwand, der zum vollständigen Eindrehen der Schraube erforderlich ist.Conventional screws consist of a shaft and a head formed at one end of this shaft, the other end of the shaft being formed as a steeply tapered tip to facilitate the penetration of this end into the object intended to receive the screw. The shaft also has a threaded part formed in an outer peripheral region which, when the screw is screwed into the object in question, enters into close engagement with the material of this object, thereby resisting the forward movement of the screw within this object. This increases the amount of force required to screw the screw in completely.
Durch die vorliegende Erfindung soll eine verbesserte Schraube geschaffen werden, die über ein Gewindeteil mit daran angeformten Schneidzähnen verfügt, um das Eindrehen der Schraube zu erleichtern und damit die vorgenannten Probleme abzuschwächen bzw. zu vermeiden.The present invention seeks to provide an improved screw having a threaded portion with molded-on cutting teeth to facilitate screwing in the screw and thus mitigate or avoid the aforementioned problems.

Brief description of the invention
Die vorliegende Erfindung sieht eine Schraube mit einem Schaft vor, der an einem ersten Ende einen Kopf trägt und an dessen zweiten Ende eine steil zulaufende Spitze ausgebildet ist. Dieser Schaft verfügt in einem Bereich seines äußeren ümfangs über ein Gewindeteil, das mindestens einen Abschnitt mit daran radial ausgebildeten Schneidzähnen aufweist.The present invention provides a screw with a shaft that has a head at a first end and a steeply tapered tip at the second end. This shaft has a threaded part in an area of its outer circumference, which has at least one section with radially formed cutting teeth.
Eine Aufgabe der vorliegende Erfindung besteht darin, eine Schraube mit mehreren an ihr ausgebildeten Schneidzähnen dergestalt zu schaffen, daß sich die Schraube effizient in einen Gegenstand eindrehen läßt.An object of the present invention is to provide a screw with a plurality of cutting teeth formed thereon such that the screw can be efficiently screwed into an object.
Weitere Aufgaben, Vorteile und neuartige Merkmale der Erfindung sind aus der folgenden detaillierten Beschreibung mit den dazugehörigen Abbildungen ersichtlich. Further objects, advantages and novel features of the invention will become apparent from the following detailed description with the accompanying drawings.

PATENTANWÄLTE · HEMMERI^y··IYP-LBf^«qOSSE ;}*C>L.LMEIER · VALENTIN · GIHSKE Detaillierte Beschreibung der bevorzugten Ausführunqsform PATENT ATTORNEYS · HEMMERI^y··IYP-LBf^«qOSSE ;}*C>L.LMEIER · VALENTIN · GIHSKE Detailed description of the preferred embodiment
Die Abbildungen 1 bis 3 zeigen zunächst eine erfindungsgemäße Schraube, die allgemein einen Schaft 10, einen an einem ersten Ende dieses Schaftes 10 ausgebildeten Kopf 12 sowie eine an einem zweiten Ende des Schaftes 10 ausgebildete, steil zulaufende Spitze 11 aufweist. An dem Schaft 10 ist in einem äußeren Umfangsbereich ein Gewindeteil 20 ausgebildet, an dem wiederum in seinem unteren Bereich mehrere radial verlaufende Schneidzähne 22 ausgebildet sind.Figures 1 to 3 first show a screw according to the invention, which generally has a shaft 10, a head 12 formed at a first end of this shaft 10 and a steeply tapered tip 11 formed at a second end of the shaft 10. A threaded part 20 is formed on the shaft 10 in an outer circumferential area, on which in turn a plurality of radially extending cutting teeth 22 are formed in its lower area.
Wie aus Abb. 4 ersichtlich ist, schneiden diese Schneidzähne beim Eindrehen der Schraube in einen Holzkörper 30 in das Holz ein. Wird die Schraube demnach durch einen (nicht abgebildeten) Benutzer eingedreht, so durchschneiden die Schneidzähne 22 wirksam das Holz und erleichtern damit das effiziente Einschrauben in den Holzkörper 30, wobei das ohne Schneidzähne 22 ausgeführte Gewindeteil 20 mit dem Holzkörper 30 eng in Eingriff geht und sich die Schraube nicht nur leicht in den Holzkörper 30 eindrehen läßt, sondern auch fest in diesem Holzkörper 30 verankert wird.As can be seen from Fig. 4, these cutting teeth cut into the wood when the screw is screwed into a wooden body 30. When the screw is therefore screwed in by a user (not shown), the cutting teeth 22 effectively cut through the wood and thus facilitate efficient screwing into the wooden body 30, whereby the threaded part 20 designed without cutting teeth 22 engages closely with the wooden body 30 and the screw can not only be easily screwed into the wooden body 30, but is also firmly anchored in this wooden body 30.
Die Schraube läßt sich auf diese Weise effizient in den Holzkörper 30 eindrehen, wobei sich die Ausführung bzw. Anordnung der Schneidzähne je nach den Anforderungen der konkreten Anwendung gestalten läßt.In this way, the screw can be efficiently screwed into the wooden body 30, whereby the design or arrangement of the cutting teeth can be designed depending on the requirements of the specific application.
Die Erfindung wurde vorstehend mit Bezug auf ihre bevorzugte Ausführungsform erläutert. Es ist jedoch darauf hinzuweisen, daß sie sich auf vielerlei Weise abändern oder abwandeln läßt, ohne den in den nachstehenden Ansprüchen dargelegten Geist und Schutzbereich der Erfindung zu verlassen.The invention has been described above with reference to its preferred embodiment. However, it should be understood that it can be modified or altered in many ways without departing from the spirit and scope of the invention as set out in the following claims.
