Abstract

The one-part connecting element comprises a relatively short base part and a relatively large connection part with profilings on the outer surface which are formed by opposing annular notches which are of an identical diameter and the widths of which are of different sizes, so that an irregular spacing between the annular notches results. The connecting element according to the invention may be produced from any desired material, for example from plastic, cast-iron or a combination of different materials. The connecting element achieves the effect of better anchorage in the walls of drill holes of structural parts made of materials which may possibly undergo displacement, in particular chipboards. In chipboards, there are chips of different sizes, so they do not provide structural parts of a homogeneous structure. The design of the connecting element according to the invention is adapted to these conditions.

Description

Verbindungselement, insbesondere zur unsichtbaren Verbindung von flächigen Teilen bei Möbeln Die Erfindung betrifft ein Verbindungselement, , insbesondere zur unsichtbaren Verbindung von flächigen Teilen bei Möbeln, das in zylindrische Bohrungen' der zu verbindenden Teile einführbar und auf seiner Außenfläche mit Profilierungen versehen ist.Connection element, especially for the invisible connection of flat Parts in furniture The invention relates to a connecting element,, in particular for the invisible connection of flat parts in furniture, the cylindrical Bores' of the parts to be connected can be introduced and on its outer surface with profiles is provided.

Zur unsichtbaren Verbindung von flächigen Teilen bei Möbeln, z. B. zur rechtwinkligen Verbindung einer Seitenwand eines Möbelkorpus mit dem Unterboden, sind eine Vielzahl von Verbindungselementen bekannt. Diese Verbindungselemente werden in vorbereitete zylindrische Bohrungen der zu verbindenden Teile eingeführt.For the invisible connection of flat parts in furniture, e.g. B. for the right-angled connection of a side wall of a furniture body with the sub-floor, a large number of connecting elements are known. These fasteners are introduced into prepared cylindrical bores of the parts to be connected.

Bei einem aus drei Einzelteilen bestehenden Verbindungselement werden in die vorbereiteten Bohrungen entsprechend ausgebildete Hülsen oder Muffen eingeschlagen oder eingeschraubt und durch einen besonderen Dübel miteinander verbunden. Obwohl mit diesem Verbindungselement eine ausreichende Verbindung zu erzielen ist, hat sich die Verwendung von drei EinzeLteiLen für jede Einzelverbindung als erschwerend und verteuernd erwiesen.In the case of a connecting element consisting of three individual parts knocked into the prepared holes appropriately designed sleeves or sleeves or screwed in and connected to one another by a special dowel. Even though a sufficient connection can be achieved with this connecting element the use of three individual parts for each individual connection is more difficult and proven to be more expensive.

Zur Herstellung einer unsichtbaren Verbindung ist des weiteren ein einteiliges Verbindungselement bekannt, das auf einem Teil seiner Länge mit sogenannten Ringkerben zur Verbesserung der Verankerung im Bohrloch versehen ist. Diese Ringkerben sind jeweils identisch gestaltet, d.h., sie besitzen sowohl identische Durchmesser, als auch identische Breiten. Durch die identischen Breiten ist der Abstand zwischen den Ringkerben immer gleich groß.To create an invisible connection, a one-piece connecting element known that on part of its length with so-called Annular notches to improve the anchorage in the borehole is provided. These ring notches are each designed identically, i.e. they both have identical diameters, as well as identical widths. Due to the identical widths, the distance between the ring notches always the same size.

Bei der Herstellung von Möbeln finden überwiegend Spanplatten Verwendung. In diesen Upanplatten sind Späne unterschiedlicher Größenordnung vorhanden, so daß keine Bauteile mit homogener Struktur zur Verfügung stehen. Die bekannten Verbindungselemente passen sich diesen Bedingungen infolge ihrer gleichmäßigen Ausbildung schlecht an.Chipboard is predominantly used in the manufacture of furniture. In these Upan plates there are chips of different sizes, so that no components with a homogeneous structure are available. The well-known fasteners do not adapt well to these conditions due to their uniform training.

Der Erfindung liegt die Aufgabe zugrunde, ein Verbindungselement der aufgezeigten Gattung so auszubilden, daß eine bessere Verankerung in den Wandungen der Bohrlöcher von Bauteilen aus verdrängungsmöglichen Materialien, insbesondere von Spanplatten, erreichbar ist.The invention is based on the object of a connecting element of to train indicated genus so that a better anchoring in the walls the drill holes of components made of displaceable materials, in particular of chipboard, is achievable.

Erfindungsgemäß wird diese Aufgabe daduroh gelöst, daß das Verbindzlllgselemen-t aus einem Basisteil und einem Anschlußteil besteht und die ProSilierungen durch gegeneinander gerichtete und identische Durchmesser aufweisende Ringkerben gebildet sind, deren Breiten unterschiedlich groß sind. Das Basisteil kann in der Länge kürzer gegenüber dem Anschlußteil ausgebildet sein, wobei sich vorteilhafterweise die Länge des Basisteils zur Länge des Anschlußteils annähernd wie 1 : 2 bis 3 : 5 verhilt. In Ausgestaltung der Erfindung besitzen die l gkerben un- regelmaBlge terschieden große Breiten, so daß sich daraus ein unregelmäßig großer Abstand zwischen den Ringkerben ergibt.According to the invention, this object is achieved in that the connection element consists of a base part and a connection part and the profiles through Formed ring notches directed against one another and having identical diameters whose widths are different. The base part can be shorter in length be formed opposite the connection part, advantageously the length of the base part to the length of the connecting part approximately as 1: 2 to 3: 5. In an embodiment of the invention, the notches have un- regular differed great widths, so that there is an irregularly large distance between the ring notches results.

Das erSindungsgemäße Verbindungselement ist nach dem Einbau nicht mehr sichtbar. Es läßt sich äußerst schnell und einfach eine feste und vor allem dichte Verbindung von flächigen Teilen herstellen.The connecting element according to the invention is not after installation more visible. It can be fixed extremely quickly and easily and most importantly Establish a tight connection between flat parts.

Das in der Länge kürzere Basisteil wird in eine vorbereistete zylindrische Bohrung der Seitenwand eines Möbelkorpus eingedrückt oder eingeschlagen. Danach. wird der anzuschließende Ober- oder Unterboden des Möbelkorpus angeschlossen, in dem das Anschlußteil des Verbindungselementes in eine ebenfalls vorbereitete zylindrische Bohrung des Ober- oder Unterbodens eingesetzt und anschließend der Ober- oder Unterboden fest gegen die Seitenwand gedrückt bzw. gepreßt wird.The base part, which is shorter in length, is converted into a prepared cylindrical one Depressed or hammered hole in the side wall of a furniture body. Thereafter. the top or bottom of the furniture body to be connected is connected, in which the connecting part of the connecting element in a likewise prepared cylindrical Drilling of the top or bottom floor inserted and then the top or bottom floor is pressed or pressed firmly against the side wall.

Die sichere und feste Verbindung zwischen den Teilen wird dadurch erreicht, daß sich das Verbindungselement mit seinen unregelmäßig großen Ringkerbungen fest in den Wandungen der Bohrlöcher verankert.The secure and firm connection between the parts is thereby achieved that the connecting element with its irregularly large ring notches firmly anchored in the walls of the drill holes.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Die einzige Figur zeigt ein Verbindungselement in-vergrößerter Darstellung.An embodiment of the invention is shown in the drawing and is described in more detail below. The only figure shows a connecting element in-enlarged view.

Das Verbindungselement ist einteilig ausgebildet und besteht aus dem Basisteil 1 und dem Anschlußteil 2. Die Lange des Basisteils 1 verhält sich zur Länge des Anschluß- teils 2 annähernd wie 3 : 5. Auf der Außenfläche des Verbindungselements sind gegeneinander gerichtete und identische Durchmesser aufweisende Ringkerben 3 argeordnet, wobei deren Breiten unregelmäßig verschieden groß sind. Daraus ergibt sich, daß die Abstande zwischen den Ringkerben 3 unterschiedlich groß sind. Das erfindungsgemäße Verbindungselement kann aus beliebigem DXaterial hergestellt sein, z. B. aus Kunststoff, Gußeisen oder einer Kombination verschiedener Materialien.The connecting element is designed in one piece and consists of the Base part 1 and the connection part 2. The length of the base part 1 is related to Length of connecting partly 2 approximately like 3: 5. On the outer surface of the connecting element are mutually directed and identical diameters having ring notches 3 are arranged, their widths being irregularly different are great. It follows that the distances between the ring notches 3 are different are great. The connecting element according to the invention can be made of any material be made, e.g. B. made of plastic, cast iron or a combination of different Materials.

Es besteht die Möglichkeit, an einer Stirnseite des Verbindungselements, vorzugsweise an der Stirnseite des Anschlußelements 2, eine längsverlaufende mittige Ausnehmung zur Aufnahme eines Preßelements vorzusehen.It is possible to use one end of the connecting element, preferably on the end face of the connection element 2, a longitudinal central one Provide recess for receiving a pressing element.
