Description
Die Erfindung betrifft eine Spanplattenschraube.The The invention relates to a chipboard screw.
Spanplattenschrauben werden in Holz oder holzähnliche Materialien eingeschraubt. Sie haben üblicherweise eine selbstbohrende Spitze, so dass sie sich ihr Loch selbst bohren. Dabei wird das Material, aus dem das Element besteht, in die die Spanplattenschraube eingeschraubt wird, zum Teil zerschnitten und zum Teil seitlich verdrängt. Daher wirken auf den Schaft der Schraube nach dem Einschrauben der Schraube seitliche Druckkräfte ein.chipboard screws be in wood or wood-like Materials screwed in. They usually have a self-drilling Tip, so they drill their hole themselves. This is the Material of which the element consists, in which the chipboard screw is screwed in, partly cut and partly laterally repressed. Therefore act on the shaft of the screw after screwing the Screw lateral compressive forces one.
Bei den bisher bekannten Spanplattenschrauben wurden Optimierungen im Hinblick auf ein schnelles Einschrauben, dass Herstellen einer Senkung für den Schraubenkopf und hohe Auszugskräfte durchgeführt. Zur Verbesserung des Einschraubens können dabei zusätzliche schräg zum Gewinde oder achsparallel verlaufende Rippen im Bereich der Bohrspitze dienen.at The previously known chipboard screws have been optimized in the In view of a quick screwing in, making a cut for the Screw head and high pull-out forces performed. to Improvement of screwing can while additional aslant to the thread or axially parallel ribs in the drill bit serve.
Die Auszugskräfte wirken in Längsrichtung der Schraube. Auf Grund des seitlichen Einwirkens des Materials auf den Schaft sind die Schrauben in der Regel auch gegen ein Lockern gesichert.The extraction forces act in the longitudinal direction of Screw. Due to the lateral influence of the material The shank, the screws are usually against loosening secured.
Es hat sich nun herausgestellt, dass unter bestimmten Bedingungen auf Grund von wechselnden Beanspruchungen, Vibrationen oder dergleichen dennoch die Gefahr besteht, dass eine Schraube sich lockert.It has now turned out that under certain conditions Reason of changing stresses, vibrations or the like nevertheless the danger exists that a screw loosens.
Der Erfindung liegt die Aufgabe zu Grunde, eine Spanplattenschraube zu schaffen, in die auch unter wechselnden Beanspruchungen sich nicht lockert.Of the Invention is based on the object, a chipboard screw to create in which also under changing stresses themselves does not relax.
Zur Lösung dieser Aufgabe schlägt die Erfindung eine Spanplattenschraube mit den im Anspruch 1 genannten Merkmalen vor. Weiterbildungen der Erfindung sind Gegenstand von Unteransprüchen.to solution this task strikes the invention, a chipboard screw with the mentioned in claim 1 Characteristics. Further developments of the invention are the subject of Dependent claims.
Durch das Vorsehen einer Rückdrehsicherung kann gewährleistet werden, dass einerseits das Einschrauben der Schraube sich nicht oder nur unwesentlich erschwert, andererseits aber ein Zurückdrehen der Schraube auch unter wechselnden Belastungen zuverlässig verhindert wird. Schraubensicherungen sind bei metrischen Schrauben zwischen diesen und Sicherungsmuttern schon bekannt. Diese Lösungen können aber für Spanplattenschrauben keine Anregung liefern.By the provision of a reverse lock can be guaranteed be that on the one hand screwing the screw is not or only slightly more difficult, but on the other hand turning back The screw reliably prevented even under changing loads becomes. Threadlockers are between metric screws these and lock nuts already known. But these solutions can for chipboard screws none Provide stimulus.
Die Erfindung schlägt in Weiterbildung vor, dass die Rückdrehsicherung an dem Schaft der Spanplattenschraube ausgebildet ist, also nicht an dem Schraubenkopf. Das anordnen der Rückdrehsicherung an dem Schaft der Schraube hat den Vorteil, dass dort eine große Fläche zur Verfügung steht, längs der eine Berührung zwischen dem Holz oder holzähnlichen Material und der Schraube vorhanden ist. Daher kann eine wirksame Rückdrehsicherung auch unter ungünstigen Bedingungen bewirkt werden.The Invention proposes in training before that the reverse lock is formed on the shank of the chipboard screw, so not on the screw head. Arrange the reverse rotation on the shaft The advantage of the screw is that there is a large area available along the a touch between the wood or wood-like Material and the screw is present. Therefore, an effective Reversing lock also under unfavorable Conditions are effected.
In Weiterbildung der Erfindung kann vorgesehen sein, dass der Schaft der Spanplattenschraube mindestens in einem Teil des Gewindeabschnitts zwischen den Windungen einen von einer Kreisform abweichenden Querschnitt aufweist. Allein durch diese Querschnittsform kann eine Rückdrehsicherung verwirklicht werden. Bei jedem Versuch, die Schraube heraus zu schrauben, muss eine Verformung und/oder Verdrängung des Holzes oder des holzähnlichen Materials durchgeführt werden, was zu Reaktionskräften und damit zu einer Hemmung der Bewegung führt.In Development of the invention can be provided that the shaft the chipboard screw at least in a part of the threaded portion between the turns of a deviating from a circular cross-section having. Simply by this cross-sectional shape can realize a reverse rotation become. Every attempt to unscrew the screw requires a deformation and / or displacement of wood or wood-like Materials performed be, resulting in reaction forces and thus leads to an inhibition of the movement.
Ein Beispiel für eine derartige Querschnittsform besteht darin, dass der Querschnitt in Längsrichtung der Schraube verlaufende Kanten aufweist, die vorzugsweise mehr oder weniger leicht abgerundet sind. Durch die Abrundung soll erreicht werden, dass keine Schnittkräfte erzeugt werden.One example for Such a cross-sectional shape is that the cross section longitudinal the screw has extending edges, preferably more or less rounded. By rounding should be achieved be that no cutting forces be generated.
Insbesondere kann vorgesehen sein, dass der Querschnitt in Rückdrehrichtung zeigende abgerundete Kanten aufweist, also in die Richtung zeigende Kanten, in der die Schraube bewegt wird, um sie herauszuschrauben. Der Querschnitt kann beispielsweise angenähert die Form eines Sägeblatts aufweisen, also eine Sägezahnverzahnung mit abgerundeten Zähnen. Dadurch wird erreicht, dass sich das Einschrauben der Schraube nicht erschwert, dass andererseits aber eine gute Rückdrehsicherung gegeben ist.Especially can be provided that the cross section in the reverse direction pointing rounded Has edges, ie in the direction facing edges in which the Screw is moved to unscrew it. The cross section can be approximated, for example the shape of a saw blade have, so a Sägezahnverzahnung with rounded teeth. This ensures that screwing the screw is not makes difficult, on the other hand, however, given a good reverse rotation.
In nochmaliger Weiterbildung der Erfindung kann vorgesehen sein, dass der von der Kreisform abweichende Querschnitt über die gesamte Länge des Gewindeabschnitts vorhanden ist, also beispielsweise die Kanten sich über die gesamte Länge des Gewindeabschnitts erstrecken.In Further development of the invention can be provided that the deviating from the circular cross section over the entire length of Thread portion is present, so for example, the edges over the entire length extend the threaded portion.
Erfindungsgemäß kann vorgesehen sein, dass ein gewindefreier Abschnitt des Schraubenschafts, der in der Regel unterhalb des Schraubenkopfs beginnt, einen kreisförmigen Querschnitt aufweist. An dieser Stelle braucht also keine Rückdrehsicherung vorhanden zu sein.According to the invention can be provided be that a threadless section of the screw shaft, the usually below the screw head begins, a circular cross-section having. At this point, therefore, no reverse-lock safety device is required be.
Es ist aber ebenfalls möglich, dass auch ein gewindefreier Abschnitt des Schafts einen von der Kreisform abweichenden unrunden Querschnitt aufweist.It but it is also possible that also a thread-free portion of the shaft one of the circular shape has different non-round cross-section.
Bei dem Schraubengewinde der Spanplattenschraube kann es sich um ein übliches Gewinde handeln, bei dem also die Gewindekante in einer Zylindermantelfläche liegt, natürlich mit Ausnahme der Schraubenspitze.At the screw thread of Spanplat tenschraube may be a common thread, so in which the thread edge is in a cylindrical surface, of course, except for the screw tip.
Es ist aber ebenfalls möglich und wird von der Erfindung vorgeschlagen, dass es sich bei der Spanplattenschraube um eine Schraube mit einem so genannten Plastofast Gewinde handelt.It but is also possible and is proposed by the invention that it is the chipboard screw is a screw with a so-called Plastofast thread.
Ebenfalls möglich ist eine trilobulare Schraubenform.Also possible is a trilobular screw shape.
