Description

Die Erfindung betrifft eine Schraube gemäß dem Oberbegriff des Patentanspruchs.The invention relates to a screw according to the preamble of the patent claim.

Bekannt ist eine Schraube, bei welcher ihr mittleres Teil einen glatten Schaft besitzt, an den sich ein nach der Schraubenspitze zu eingeschnittenes Gewinde anschließt, dessen Durchmesser nicht über den des glatten Schaftes hinausragt. Ein bis an den Schraubenkopf reichendes Gewinde ist auf den Schraubenbolzen aufgerollt und sein Durchmesser ist größer als der des Schaftes des Schraubenbolzens. Beide Gewindeteile haben eine gleiche Steigung.A screw is known in which the middle part has a smooth shaft, to which a thread cut towards the screw tip is connected, the diameter of which does not exceed that of the smooth shaft. A thread extending to the screw head is rolled onto the screw bolt and its diameter is larger than that of the shaft of the screw bolt. Both thread parts have the same pitch.

Weiter ist eine Schraube gleicher Art bekannt, bei welcher die Gewindeabschnitte von verschiedenen Durchmessern sind. Diese Gewindeabschnitte haben entweder eine gleiche oder eine ungleiche Gewindesteigung.A screw of the same type is also known in which the thread sections have different diameters. These thread sections have either the same or different thread pitches.

Bekannt ist ebenfalls eine Doppelschraube zur Befestigung von vorgebohrten Holzplatten an einem mit Dübeln versehenen Mauerwerk, wobei zwischen den Holzplatten und der Mauer ein bestimmter Abstand ohne Verwendung spezieller Distanzelemente vorgesehen ist. Auf das Gewinde des dickeren Teils ist eine mit Innen- und Außengewinde versehene Hülse anschließend an den Schraubenkopf geschraubt. Diese Hülse verteuert jedoch die Verschraubung wesentlich. Zudem weist die Schraube einen relativ großen Senkschraubenkopf auf.A double screw is also known for fastening pre-drilled wooden panels to a wall with dowels, whereby a certain distance is provided between the wooden panels and the wall without the use of special spacers. A sleeve with an internal and external thread is screwed onto the thread of the thicker part and then onto the screw head. However, this sleeve makes the screw connection significantly more expensive. In addition, the screw has a relatively large countersunk screw head.

Aus der US-PS 31 24 031 ist eine Schraube mit einer Ausnehmung zum Einstecken eines Werkzeugs bekannt, die mit einem werkzeugseitigen, kürzeren, dickeren Gewindeteil und einem mit Gewinde versehenen dünnen Schaftteil ausgestattet ist und die ein mit Gewinde versehenes Übergangsteil aufweist, das mit einem Konuswinkel von ungefähr 90° oder etwas weniger als 90° versehen ist und bei der beide Teile etwa die gleiche Gewindehöhe aufweisen.From US-PS 31 24 031 a screw with a recess for inserting a tool is known, which is equipped with a tool-side, shorter, thicker threaded part and a threaded thin shaft part and which has a threaded transition part which is provided with a cone angle of approximately 90° or slightly less than 90° and in which both parts have approximately the same thread height.

Schließlich beschreibt die US-PS 22 92 557 eine Holzschraube mit Schraubenkopf und einem teilweise mit einem Gewinde versehenen Schaft, dessen Gewinde gleichsinnig verlaufen.Finally, US-PS 22 92 557 describes a wood screw with a screw head and a partially threaded shaft whose threads run in the same direction.

Die Aufgabe der vorliegenden Erfindung besteht nun darin, das Eintreiben eines dickeren Gewindeteiles einer Schraube wesentlich zu erleichtern und die verdrängende Wirkung des Gewindes auf die Bohrungswandung zu verringern.The object of the present invention is to make it significantly easier to drive in a thicker threaded part of a screw and to reduce the displacing effect of the thread on the bore wall.

Die Lösung dieser Aufgabe wird durch die im Kennzeichen des Patentanspruchs beschriebene technische Lehre vermittelt.The solution to this problem is provided by the technical teaching described in the characterising part of the patent claim.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Es zeigtThe drawing shows an embodiment of the subject matter of the invention. It shows

Fig. 1 die Schraube in der Ansicht, Fig. 1 the screw in the view,

Fig. 2 die Schraube als Verbindungsmittel eines Verkleidungselements mit einer mit einem Dübel versehenen Mauer. Fig. 2 the screw as a connecting element of a cladding element with a wall provided with a dowel.

Die dargestellte Schraube 1 dient insbesondere zur Befestigung von Verkleidungselementen 2, ohne auf spezielle Distanzhalterungselemente angewiesen zu sein. Als Verkleidungselemente 2 können Platten aus Holz, Span, Kunststoff, Asbestzement, etc., verwendet werden. Die Schraube 1 (Fig. 1) weist ein werkzeugseitiges, kürzeres, dickeres Gewindeteil 4, ein konisches Übergangsteil 5 sowie ein längeres, dünneres, mindestens teilweise mit Gewinde versehenes Teil 6 auf. Dieses ist im Beispiel nach Fig. 1 auf seiner ganzen Länge mit Gewinde versehen. In Fig. 2 ist es am konischen Übergangsteil 5 zur Verstärkung mit einem gewindefreien Teilstück 6 a ausgebildet. Alle Gewindeteile 4, 5 und 6 sind mit einem Holzschraubengewinde derselben Ganghöhe versehen. Dadurch wird verhindert, daß beim Einschrauben des dickeren Teils 4 das entstandene Gewinde im Verkleidungselement 2 und/oder das durch das dünnere Gewindeteil 6 im Verankerungskörper 3, 7 entstandene Gewinde zerstört wird.The screw 1 shown is used in particular for fastening cladding elements 2 without having to rely on special spacer elements. Panels made of wood, chipboard, plastic, asbestos cement, etc. can be used as cladding elements 2. The screw 1 ( Fig. 1) has a shorter, thicker threaded part 4 on the tool side, a conical transition part 5 and a longer, thinner part 6 that is at least partially threaded. In the example according to Fig. 1, this is threaded along its entire length. In Fig. 2 , it is formed with a thread-free section 6a on the conical transition part 5 for reinforcement. All threaded parts 4, 5 and 6 are provided with a wood screw thread of the same pitch. This prevents the thread created in the cladding element 2 and/or the thread created by the thinner threaded part 6 in the anchoring body 3, 7 from being destroyed when the thicker part 4 is screwed in.

Das konische Übergangsgewindeteil 5 ist mit einem Konuswinkel zwischen 30° und 90° vorgesehen. Als Ausnehmung 8 weist das werkzeugseitige, dickere Gewindeteil 4 einen Innensechskant, Innendreikant, Kreuzschlitz, Querschlitz oder eine Einsteckrosette, deren Querschnitt durch vier Kreisbogenstücke begrenzt ist, auf, die zum Einstecken eines Schlüssels oder Schraubenziehers dient. Vorteilhafterweise ist das dünnere Teil 6 an seinem freien Ende mit einem kurzen Konus 9 ausgebildet.The conical transition thread part 5 is provided with a cone angle between 30° and 90°. The tool-side, thicker thread part 4 has a recess 8 in the form of a hexagon socket, triangle socket, Phillips slot, transverse slot or an insert rosette whose cross section is limited by four circular arcs, which serves to insert a key or screwdriver. The thinner part 6 is advantageously designed with a short cone 9 at its free end.

Das konische Übergangsteil ist mit mindestens zwei Spannuten 10 versehen, die sich teilweise über das dickere Gewindeteil 4 erstrecken. Die Spannuten 10 weisen je eine Schneidkante auf. Diese bewirken am Verkleidungselement 2 einen Spanausschnitt, wodurch die materialverdrängende Wirkung des dickeren Gewindeteils 4 reduziert und eine saubere Bohrlochkante, ohne Blähung des Materials, erreicht wird.The conical transition part is provided with at least two chip grooves 10 , which extend partially over the thicker threaded part 4. The chip grooves 10 each have a cutting edge. These cause a chip cutout on the cladding element 2 , whereby the material-displacing effect of the thicker threaded part 4 is reduced and a clean borehole edge is achieved without swelling of the material.

Nach Fig. 2 dient die Schraube 1 zur Befestigung eines aus Holz bestehenden Verkleidungselements 2 in einem bestimmten Abstand an einer mit Dübeln 7 versehenen Mauer 3, ohne daß ein spezielles Distanzelement erforderlich ist. In entsprechender Weise kann auch ein aus Holz bestehendes Verkleidungselement 2 mit der Schraube 1 in einem ebenfalls aus Holz bestehenden Verankerungsteil befestigt werden. Der Unterschied im Durchmesser der Schraubenteile 4 und 6 kann dann bedeutend kleiner gewählt werden, als bei der Befestigung des Verkleidungselements 2 an der mit Dübeln 7 versehenen Mauer 3 nach Fig. 2.According to Fig. 2, the screw 1 is used to fasten a cladding element 2 made of wood at a certain distance to a wall 3 provided with dowels 7 , without a special spacer element being required. In a similar way, a cladding element 2 made of wood can also be fastened with the screw 1 in an anchoring part that is also made of wood. The difference in the diameter of the screw parts 4 and 6 can then be chosen to be significantly smaller than when fastening the cladding element 2 to the wall 3 provided with dowels 7 according to Fig. 2.

Das dickere Gewindeteil 4 kann vorteilhafterweise auch ganz im Verkleidungselement 2 versenkt und zugedeckt werden, was eine Schraube mit Senkkopf nicht erlaubt.The thicker threaded part 4 can advantageously also be completely countersunk and covered in the cladding element 2 , which is not possible with a screw with a countersunk head.
