Die Erfindung bezieht sich auf einen Dübel, insbesondere zur Verankerung in einer Spanplatte, mit einem Dübelkörper mit am Mantel angeordneten Befestigungsrippen,, wobei der Dübelkörper mit den Befestigungsrippen aus nachgiebigem, elastischem Material ist und in der Einschlagrichtung des Dübels die vorderen und hinteren.Begrenzungsflächen bei zumindestens einem Teil der Befestigungsrippen jeweils in einer senkrecht oder annährend senkrecht zur Längsmittelachse L-L des Dübels verlaufende Ebene liegen.The invention relates to a dowel, in particular for anchoring in a chipboard, with a dowel body with fastening ribs arranged on the jacket, the dowel body with the fastening ribs made of flexible, elastic material and the front and rear boundary surfaces in the direction of impact of the dowel at least part of the fastening ribs each in a perpendicular or approximately perpendicular to the longitudinal center axis L-L of the anchor lie level.
Derartige Dübel finden als Verbindungs- und als Halteelemente im modernen Möbelbau vielfältige Verwendung.Such dowels are used in a wide variety of ways as connecting and holding elements in modern furniture construction.
Außer dem eigentlichen Dübelkörper, der im allgemeinen aus Kunststoff gefertigt ist, weisen sie noch einen Verankerungsteil auf, der in ein Loch des Dübelkörpers in axialer Richtung eingeschoben werden kann oder sonstwie am Dübelkörper gehalten ist und der die Verbindung mit dem zu tragenden Teil, beispielsweise eine Grundplatte für ein Scharnier darstellt.In addition to the actual dowel body, which is generally made of plastic, they also have one Anchoring part that can be pushed into a hole in the anchor body in the axial direction or otherwise is held on the dowel body and the connection with the part to be carried, for example a base plate represents for a hinge.
Dieser Verankerungsteil kann auch als Spreizelement ausgebildet sein.This anchoring part can also be designed as an expanding element.
Zur Verbesserung des Haltes eines derartigen Dübels sind diese mit Halterippen versehen, wobei diese Halterippen im allgemeinen in etwa Tannenzapfenumrisse haben, so daß der Dübel leicht in die Bohrung des Möbels eingeführt werden kann, sich aber beim Herausziehen, d.h. beim Auftreten einer starken Belastung an der Bohrungsseitenwand verspreizt.To improve the hold of such a dowel are these are provided with retaining ribs, these retaining ribs generally having roughly pine cone outlines, so that the dowel can easily be inserted into the hole in the furniture, but when it is pulled out, i.e. when stepping on a strong load on the side wall of the bore spread.
Es ist aber noch ein Dübel bekannt, bei dem die Begrenzungsflächen der Halterippen rechtwinkelig zu einanderBut there is still another dowel known in which the boundary surfaces the retaining ribs at right angles to each other

Aufgabe der Erfindung ist es,'einen Dübel der eingangs erwähnten Art zu schaffen, der nicht nur einen optimalen Halt, d.h. eine optimale Verspreizung des Dübels in der Möbelbohrung bietet, sondern der auch bis zu einem gewissen Grad einen Rückholeffekt aufweist, d.h., tritt eine übermäßige Belastung auf, dann wird der Dübel geringfügig aus der. Bohrung herausgezogen, wobei sich aber die Haltekraft des Dübels in der Bohrung verstärkt, um dann beim Nachlassen der Belastung den Dübel selbsttätig in die Bohrung zurückzuziehen.The object of the invention is to 'a dowel of the initially mentioned type, which not only provides an optimal hold, i.e. an optimal expansion of the anchor in the Furniture drilling offers, but which also has a pull-back effect to a certain extent, i.e., kicks Excessive stress will then cause the dowel to slip slightly out of the. Hole pulled out, but the The holding force of the dowel in the hole is increased so that the dowel automatically moves into place when the load is released retract the hole.
Dies wird erfindungsgemäß dadurch erreicht, daß der radiale Vorsprung der Rippen größer als die Breite der Rippen ist.This is achieved according to the invention in that the radial projection of the ribs is greater than the width of the Ribs is.
Vorteilhaft ist vorgesehen, daß die Innenkanten zwischen den vorderen und hinteren Begrenzungsflächen drr Rippen und dem Dübelmantel abgerundet sind. Dadurch wird ein Abbrechen der Rippen während der Verformung derselben vermieden.It is advantageously provided that the inner edges between the front and rear boundary surfaces drr ribs and the dowel jacket are rounded. This causes the ribs to break off during the deformation of the same avoided.
Nachstehend wird ein Ausführungsbeispiel der Erfindung anhand der Figuren der beiliegenden Zeichnung eingehend beschrieben.The following is an embodiment of the invention described in detail with reference to the figures of the accompanying drawing.
Die Fig. 1 zeigt eine Seitenansicht auf einen erfindungsgemäßen Dübel, die Fig. 2 zeigt eine gleiche Seitenansicht, wobei der Dübel um 90 gedreht ist, die Fig. 3 zeigt eine Draufsicht auf einen Dübel gemäß der Fig. 1, die Fig. 4 zeigt schematisch den Ausschnitt A der Fig. bei einem Dübel, der in eine Möbelbohrung eingeschlagen ist, und die Fig. 5 zeigt den gleichen Ausschnitt bei stark belastetem Dübel.FIG. 1 shows a side view of a dowel according to the invention, FIG. 2 shows the same side view. wherein the dowel is rotated by 90, FIG. 3 shows a plan view of a dowel according to FIG. 1, Fig. 4 shows schematically the section A of the figure with a dowel hammered into a furniture hole is, and Fig. 5 shows the same section with a heavily loaded dowel.
130026/0351130026/0351
Der erfindungsgemäße Dübel besteht aus einem kunststoffgefertigten Dübelkörper 1, der entlang seines Umfangs mit einer Mehrzahl von Rippen 2 versehen ist.The dowel according to the invention consists of a plastic one Dowel body 1, which along its circumference is provided with a plurality of ribs 2.
Innen weist der Dübelkörper. 1 einen durchgehenden Kanal 3 auf , der beispielsweise zur Aufnahme eines Verankerungsstiftes oder eines Spreizstiftes geeignet ist, seitlich sind die Rippen 2 an zwei Stellen 4 nutenartig durchbrochen, so daß beim Einschlagen des Dübels in die Möbelwand die Luft aus der Bohrung entweichen kann.The dowel body faces inside. 1 a continuous channel 3, which is suitable for example for receiving an anchoring pin or an expanding pin, laterally the ribs 2 are perforated like a groove at two points 4, so that when the dowel is hammered into the Furniture wall the air can escape from the hole.
Weiters sind noch Positionierungszapfen 5 vorgesehen, die in die korrespondierende öffnung eines Beschlages ragen.In addition, positioning pins 5 are also provided, which fit into the corresponding opening of a fitting protrude.
Die Rippen 2 sind derartig ausgebildet, daß, soferne sie nicht unter Belastung verbogen werden,, die vordere Begrenzungsfläche 6 und die rückwärtige Begrenzungsfläche 7 jeweils in einer Ebene liegen, die zumindestens im wesentlichen senkrecht zur Einschlagrichtung E des Dübels ausgerichtet ist.The ribs 2 are designed such that, if they not be bent under load, the front boundary surface 6 and the rear boundary surface 7 each lie in a plane that is at least in the is aligned essentially perpendicular to the direction of impact E of the anchor.
Die umfangsseitige Begrenzungsfläche 8 ist im Ausführungsbeispiel Teil eines Zylindermantels. In the exemplary embodiment, the peripheral boundary surface 8 is part of a cylinder jacket.
Auf diese Art und Weise, da der radiale Vorsprung rV der Rippen 2 größer als die Breite b der Rippen ist, haben die Rippen im wesentlichen rechteckigen Querschnitt, wobei die reine Rechteckform lediglich durch die abgerundeten Ecken 9 zwischen den Begrenzungsflächen 7, 6 und dem Innenmantel 10 des Dübels durchbrochen wird.In this way, since the radial projection rV of the ribs 2 is greater than the width b of the ribs the ribs have a substantially rectangular cross-section, the pure rectangular shape being only due to the rounded ones Corners 9 between the boundary surfaces 7, 6 and the inner jacket 10 of the anchor is broken.
Wird der erfindungsgemäße Dübel in eine Dübelbohrung eingeschlagen, so werden die Rippen 2, wie in der Fig.If the dowel according to the invention is hammered into a dowel hole, the ribs 2, as shown in FIG.

gezeigt, durch die Bohrungswand 11 leicht zurückgebogen, wobei sie sich jedoch an der Bohrungswand 11 verspreizen.shown, slightly bent back through the bore wall 11, however, they expand on the bore wall 11.
Wird jetzt der Dübel einer starken, übermäßigen Belastung ausgesetzt, wie es beispielsweise vorkommen kann, wenn der Dübel als Befestigungsmittel für eine Grundplatte eines Scharniers Verwendung findet und der Türflügel über den Anschlag geöffnet wird, dann wird der Dübel, wie in der Fig. 5 gezeigt, geringfügig aus der Bohrung herausgezogen, die Rippen 2 werden verformt und zusammengepreßt. The dowel is now under a strong, excessive load exposed, as can happen, for example, when the dowel is used as a fastening means for a base plate a hinge is used and the door leaf is opened over the stop, then the dowel is, like shown in Fig. 5, slightly pulled out of the bore, the ribs 2 are deformed and pressed together.
Dadurch wird aber der Haltedruck der Rippen, d.h. die Spreizwirkung der Rippen erhöht.However, this increases the holding pressure of the ribs, i.e. the spreading effect of the ribs.
Läßt die Belastung nach, wird der Dübel durch die Rippen 2, die das Bestreben-■ haben, -in die in der Fig. 4 gezeigte Lage zu kommen, selbsttätig in die Bohrung hineingezogen. If the load subsides, the dowel becomes the one shown in FIG. 4 by the ribs 2, which endeavor Able to come automatically drawn into the bore.
