Abstract

The arrangement relates to an arrangement (11) having a hollow plate (1), for example a honeycomb plate, and a connecting fitting (6). For stable fastening, the invention proposes to insert the connecting fitting (6) through a hole in a covering plate (3) of the hollow plate (1) into a countersunk depression on the inner side of the other covering plate (4) of the hollow plate (1). As a result, the connecting fitting (6) is supported in a stable manner against forces in the radial direction, that is to say against forces which act in the plate plane. For example, a clamping eccentric (19) which is known per se and by way of which a tie rod (14) can be clamped by rotation can be inserted into the connecting fitting (6).

Anordnung mit einer Hohlplatte und einem VerbindungsbeschlagArrangement with a hollow plate and a connection fitting
Die Erfindung betrifft eine Anordnung mit einer Hohlplatte und einem Verbindungsbeschlag gemäß dem Oberbegriff des Anspruchs 1. MitThe invention relates to an arrangement with a hollow plate and a connection fitting according to the preamble of claim 1. Mit
„Verbindungsbeschlag" ist insbesondere ein Teil eines mehrteiligen Verbindungsbeschlags gemeint."Connection fitting" is meant in particular a part of a multi-part connection fitting.

Sie weisen zwei voneinander beabstandete und zueinander paralleleThe invention is directed to the provision of a connection or a Verbindüngsmöglichkeit with a hollow plate. Such hollow slabs are used in the furniture industry. They have two spaced apart and parallel to each other
Deckplatten auf, die beispielsweise durch eine Wabenstruktur miteinander verbunden sind. In diesem Fall spricht man auch von einer Wabenplatte. Ein Verbindungsbeschlag zur Verbindung der Hohlplatte mit einem anderen Bauteil muss an einer der beiden Deckplatten der Hohlplatte befestigt werden, weil der Zwischenraum zwischen den beiden Deckplatten keine ausreichend stabile Verankerungsmöglichkeit bietet.Cover plates, which are interconnected for example by a honeycomb structure. In this case one speaks also of a honeycomb plate. A connection fitting for connecting the hollow plate with another component must be attached to one of the two cover plates of the hollow plate, because the space between the two cover plates does not provide a sufficiently stable anchoring opportunity.
Problematisch ist die Befestigung eines Verbindungsbeschlags dann, wenn dieThe problem is the attachment of a connection fitting when the
Hohlplatte „auf Stoß", also mit einem ihrer Ränder gegen das andere Bauteil stoßend mit dem anderen Bauteil verbunden werden soll, weil in diesem Fall Zugkräfte von der Hohlplatte aufzunehmen sind, die in ihrem Zwischenraum in einer Plattenebene wirken.Hollow plate "on impact", ie with one of its edges against the other component abutting with the other component to be connected, because in this case tensile forces are to be absorbed by the hollow plate, which act in their space in a plane of the plate.
Für Vollplatten, also beispielsweise massive oder geleimte Holzplatten, sind Spannexzenter zur Verbindung der Platte auf Stoß bekannt. Die Spannexzenter weisen ' eine Zylinderform auf. Sie sind hohl und weisen einen in Umfangsrichtung verlaufenden Schlitz auf, dessen Schlitztiefe sich in Umfangsrichtung spiralförmig vergrößert. DurchFor solid plates, so for example, solid or glued wooden panels, clamping eccentric are known for connecting the plate to shock. The clamping eccentric 'have a cylindrical shape. They are hollow and have a circumferentially extending slot whose slot depth increases in the circumferential direction spiral. By
Drehung des Spannexzenters wird ein Kopf eines durch den Schlitz greifenden Zugankers tiefer in den Spannexzenter gezogen, wodurch sich die Platte auf Stoß gegen ein anderes Bauteil spannen lässt. Der Spannexzenter wird in ein zylindrisches Sackloch der Vollplatte eingesetzt. Für eine Hohlplatte sind solche Spannexzenter ungeeignet, weil sie keinen ausreichenden Halt im Zwischenraum zwischen den Deckplatten finden. Um einen derartigen Spannexzenter drehbar in einer Hohlplatte zu befestigen, sieht das Gebrauchsmuster DE 20 2005 007 822 U1 einen zweiteiligen Beschlag mit einer Art Muffe und einem axial in Stufen einrastbaren Gegenstück vor, das einen Fuß in Form eines Senkkopfs einer Schraube aufweist. Der bekannte Beschlag wird durch ein Loch in einer der beiden Deckplatten in eine Hohlplatte eingesetzt, so dass der Fuß auf derTurning the clamping eccentric, a head of a tie rod passing through the slot is pulled deeper into the clamping eccentric, allowing the plate to be clamped against another component in abutment. The clamping eccentric is inserted into a cylindrical blind hole of the solid plate. For a hollow plate such clamping eccentric are unsuitable because they do not find sufficient support in the space between the cover plates. In order to fix such a clamping eccentric rotatably in a hollow plate, the utility model DE 20 2005 007 822 U1 provides a two-part fitting with a kind of sleeve and an axially snap-in stages counterpart, which has a foot in the form of a countersunk head of a screw. The well-known fitting is inserted through a hole in one of the two cover plates in a hollow plate, so that the foot on the
Innenseite der anderen Deckplatte anliegt. Der Fuß wird mit der Deckplatte verklebt. Der bekannte Beschlag hat dadurch Halt in radialer Richtung im Loch in der einen Deckplatte und durch die Verklebung mit der anderen Deckplatte. Der bekannte Spannexzenter wird in das muffenförmige Teil des bekannten Beschlags eingesetzt und kann dann wie gewohnt verwendet werden.Inside of the other cover plate is applied. The foot is glued to the cover plate. The known fitting thus has hold in the radial direction in the hole in the one cover plate and by the bond with the other cover plate. The known clamping eccentric is inserted into the sleeve-shaped part of the known fitting and can then be used as usual.
Eine insoweit vergleichbare Lösung offenbart die Offenlegungsschrift DE 10 2005 060 528 A1 , die vorschlägt, einen hülsenförmigen Einsatzkörper durch ein Loch in einer der beiden Deckplatten in eine Hohlplatte einzusetzen und mit der Innenseite der anderen Deckplatte stoffschlüssig beispielsweise durch Aufschmelzen eines thermoplastischen Kunststoffs mittels Ultraschall zu verbinden. Auch hier hat der Einsatzkörper wie im vorstehend erörterten Gebrauchsmuster Halt an beiden Deckplatten und kann dadurch in radialer Richtung, also im Zwischenraum zwischen den Deckplatten der Hohlplatte und in der Plattenebene belastet werden.A so far comparable solution disclosed in the published patent application DE 10 2005 060 528 A1, which proposes to insert a sleeve-shaped insert body through a hole in one of the two cover plates in a hollow plate and to connect the inside of the other cover plate cohesively, for example by melting a thermoplastic material by means of ultrasound , Again, the insert body as in the above-discussed utility model hold on both cover plates and can thereby be charged in the radial direction, ie in the space between the cover plates of the hollow plate and in the plane of the plate.
Aufgabe der Erfindung ist es, eine Anordnung mit einer Hohlplatte und einem Verbindungsbeschlag vorzuschlagen, der ohne Stoffschluss in der Hohlplatte befestigbar ist und guten Halt gegen Kräfte hat, die im Zwischenraum der Hohlplatte in der Plattenebene wirken.The object of the invention is to propose an arrangement with a hollow plate and a connection fitting which can be fastened without material connection in the hollow plate and has good support against forces acting in the space between the hollow plate in the plane of the plate.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Der Verbindungsbeschlag der erfindungsgemäßen Anordnung ist in einem Loch in der einen der beiden Deckplatten der Hohlplatte angeordnet und er steht auf einer Innenseite der anderen Deckplatte formschlüssig mit der anderen Deckplatte der Hohlplatte in Eingriff. Der Formschluss kann beispielsweise durch eine oder mehrere Spitzen oder eine oder mehrere einander beispielsweise waffelartig kreuzende Schneiden auf einer Stirnfläche des Verbindungsbeschlags bewirkt sein, die sich in die Innenseite der anderen Deckplatte der Hohlplatte einformen. Ein Verkleben oder sonstiges stoffschlüssiges Verbinden des Verbindungsbeschlags mit einer oder mit beiden Deckplatten der Hohlplatte ist nicht erforderlich, wird allerdings von der Erfindung auch nicht ausgeschlossen. In der Plattenebene stützt sich der Verbindungsbeschlag an beiden Deckplatten der Hohlplatte durch Formschluss ab und ist dadurch stabil in der Hohlplatte gehalten. Er kann dadurch die zur Verbindung der Hohlplatte auf Stoß erforderlichen Kräfte aufnehmen. Bei einem Lösen der Verbindung beispielsweise zum Zerlegen eines Möbels kann der Verbindungsbeschlag in der Hohlplatte verbleiben und ist ohne Verschlechterung seines Halts in der Hohlplatte wiederverwendbar. Das gilt auch für ein mehrfaches Lösen und erneutes Verbinden der Hohlplatte. Der Verbindungsbeschlag kann zum Eindrehen einer Schraube dienen, er kann als Spannexzenter der eingangs erläuterten Art ausgebildet sein oder eine zylindrische Höhlung zur drehbaren Aufnahme eines solchen Spannexzenters aufweisen. Die Befestigung des Verbindungsbeschlags in der erfindungsgemäßen Anordnung in der Hohlplatte ist schnell, einfach und mit imThis object is achieved by the features of claim 1. The connection fitting of the arrangement according to the invention is arranged in a hole in one of the two cover plates of the hollow plate and it is on an inner side of the other cover plate form-fitting manner with the other cover plate of the hollow plate in engagement. The positive connection can be effected for example by one or more tips or one or more, for example waffle-like intersecting cutting edges on an end face of the connection fitting, which form into the inside of the other cover plate of the hollow plate. Bonding or other cohesive connection of the connection fitting with one or both cover plates of the hollow plate is not required, but is not excluded by the invention. In the plane of the board, the connection fitting is based on both Cover plates of the hollow plate by positive engagement and is thus held stable in the hollow plate. He can thereby absorb the forces required to connect the hollow plate to shock. When releasing the connection, for example, to disassemble a piece of furniture, the connection fitting can remain in the hollow plate and is reusable without deterioration of his stop in the hollow plate. This also applies to multiple loosening and reconnecting the hollow plate. The connection fitting can serve for screwing in a screw, it can be designed as a clamping eccentric of the type described above or have a cylindrical cavity for rotatably receiving such a clamping eccentric. The attachment of the connection fitting in the inventive arrangement in the hollow plate is fast, easy and with in
Möbelbau vorhandenem Handwerkszeug herstellbar, der Verbindungsbeschlag ist nach dem Einsetzen in die Hohlplatte sofort voll belastbar.Furniture making existing tools can be produced, the connection fitting is immediately fully loaded after insertion into the hollow plate.
In bevorzugter Ausgestaltung der Erfindung greift der Verbindungsbeschlag in eine Ansenkung auf der Innenseite der anderen Deckplatte ein. Die Ansenkung lässt sich beim Bohren des Lochs in der einen Deckplatte herstellen.In a preferred embodiment of the invention, the connection fitting engages in a countersink on the inside of the other cover plate. The countersink can be made by drilling the hole in the one cover plate.
Vorzugsweise ist die Anordnung so ausgeführt, dass sie auf der Außenseite der anderen Deckplatte nicht sichtbar ist. Das bedeutet, die Außenseite der anderen Deckplatte wird durch die Anbringung des Verbindungsbeschlags in der Hohlplatte nicht verändert, diePreferably, the arrangement is designed so that it is not visible on the outside of the other cover plate. This means that the outside of the other cover plate is not changed by the attachment of the connection fitting in the hollow plate, the
Außenseite der anderen Deckplatte kann dadurch als Sichtseite der Hohlplatte verwendet werden.Outside of the other cover plate can be used as a visible side of the hollow plate.
Zur Anpassung an unterschiedliche Dicken verschiedener Hohlplatten sieht eine Ausgestaltung der Erfindung einen teleskopierbaren Verbindungsbeschlag vor, womit gemeint ist, dass seine Länge oder allgemeiner ausgedrückt seine Abmessung in Dickenrichtung der Hohlplatte veränderbar ist.To adapt to different thicknesses of different hollow plates, an embodiment of the invention provides a telescopic connection fitting, which means that its length or more generally its dimension in the thickness direction of the hollow plate is variable.
Eine Ausgestaltung der Erfindung sieht vor, dass der Verbindungsbeschlag als Senkbohrer ausgebildet ist, mit dem die Ansenkung auf der Innenseite der anderenAn embodiment of the invention provides that the connection fitting is designed as a countersink, with which the countersink on the inside of the other

Die Erfindung wird nachfolgend anhand in der Zeichnung dargestellter Ausführungsbeispiele näher erläutert. Die drei Figuren zeigen drei Ausführungsbeispiele erfindungsgemäßer Anordnungen in einer Schnittdarstellung.The invention will be explained in more detail with reference to embodiments illustrated in the drawings. The three figures show three embodiments of inventive arrangements in a sectional view.
In Figur 1 ist eine Hohlplatte 1 mit einer weiteren Platte 2 verbunden. Die Hohlplatte 1 ist eine Wabenplatte mit zwei Deckplatten 3, 4, die mit Abstand voneinander und parallel zueinander angeordnet sind und mit einer Wabenstruktur 5 miteinander verbunden sind. Die andere Platte 2 ist ebenfalls eine Wabenplatte, was jedoch hier nicht von Bedeutung ist. Die Hohlplatte 1 ist auf Stoß zur anderen Platte 2 angeordnet, d.h. sie „stößt" mit einem Rand gegen die andere Platte 2. In die Hohlplatte 1 ist ein VerbindungsbeschlagIn FIG. 1, a hollow plate 1 is connected to a further plate 2. The hollow plate 1 is a honeycomb plate with two cover plates 3, 4, which are spaced apart and parallel to each other and are connected to a honeycomb structure 5 together. The other plate 2 is also a honeycomb plate, but this is not important here. The hollow plate 1 is arranged in abutment with the other plate 2, i. she "pushes" with an edge against the other plate 2. In the hollow plate 1 is a connection fitting
6 eingesetzt. Der Verbindungsbeschlag 6 ist rohrförmig, er weist einen senkkopfartigen Flansch 7 an einem Stirnende auf. Mit einem der Dicke der einen Deckplatte 3 entsprechenden Abstand von diesem Ende weist der Verbindungsbeschlag 6 federnde Rastnasen 8 auf. Die Rastnasen 8 sind widerhakenförmig, sie sind über den Umfang des rohrförmigen Verbindungsbeschlags 6 gleichmäßig oder auch ungleichmäßig verteilt angeordnet, stehen seitlich über und können nach innen in Aussparungen des Verbindungsbeschlags 6 federn. Das den Flansch 7 aufweisende Ende des Verbindungsbeschlags 6 ist durch eine Stirnwand 9 verschlossen, die einen Kreuzschlitz 10 oder auch einen sonstigen Werkzeugsitz wie beispielsweise einen Querschlitz oder einen Innensechskant (nicht dargestellt) zum Ansetzen eines nicht dargestellten6 used. The connecting fitting 6 is tubular, it has a senkkopfartigen flange 7 at a front end. With one of the thickness of a cover plate 3 corresponding distance from this end, the connecting fitting 6 resilient locking lugs 8. The locking lugs 8 are barb-shaped, they are distributed over the circumference of the tubular connection fitting 6 evenly or unevenly distributed, stand laterally over and can spring inwards in recesses of the connection fitting 6. The flange 7 having the end of the connecting fitting 6 is closed by an end wall 9 having a cross recess 10 or other tool seat such as a transverse slot or a hexagon socket (not shown) for attachment of a not shown
Drehwerkzeugs aufweist. Das andere Ende des Verbindungsbeschlags 6 ist offen. Zum Einsetzen des Verbindungsbeschlags 6 ist durch die eine Deckplatte 3 der Hohlplatte 1 ein Loch gebohrt. Die andere Deckplatte 4 ist mit einer zylindrischen Ansenkung auf ihrer Innenseite versehen. Der Verbindungsbeschlag 6 ist in das Loch in der einen Deckplatte 3 eingesetzt, der senkkopfartige Flansch 7 ist bündig in dieTurning tool has. The other end of the connection fitting 6 is open. To insert the connection fitting 6 a hole is drilled through the one cover plate 3 of the hollow plate 1. The other cover plate 4 is provided with a cylindrical countersink on its inside. The connecting fitting 6 is inserted into the hole in the one cover plate 3, the senkkopfartige flange 7 is flush in the
Deckplatte 3 versenkt. Die Rastnasen 8 sind auf einer Innenseite der Deckplatte 3 nach außen gefedert und hintergreifen die Deckplatte 3 auf der Innenseite. Der Verbindungsbeschlag 6 ist dadurch axial in der Deckplatte 3 fixiert und drehbar. Das andere Ende des Verbindungsbeschlags 6 greift in die Ansenkung auf der Innenseite der anderen Deckplatte 4 der Hohlplatte 1 ein. Der Verbindungsbeschlag 6 ist dadurch an seinen beiden Enden formschlüssig in den Deckplatten 3, 4 der Hohlplatte 1 gegen Belastungen in radialer Richtung gehalten. Er kann dadurch hohe Kräfte aufnehmen, die im Zwischenraum zwischen den beiden Deckplatten 3, 4 der Hohlplatte 1 in deren Plattenebene wirken. Die Hohlplatte 1 mit dem in sie eingesetzten und sich in beiden Deckplatten 3, 4 radial durch Formschluss abstützenden Verbindungsbeschlag 6 bildet eine Anordnung 11 gemäß der Erfindung. Die Rastnasen 8 bilden Hintergriffelemente, die die eine Deckplatte 3 der Hohlplatte 1 auf deren Innenseite hintergreifen. Die Ansenkung auf der Innenseite der anderen Deckplatte 4 der Hohlplatte 1 muss nicht zwingend zylinderförmig sein, sie kann beispielsweise auch kegelförmig entsprechend einer Spitze eines zum Bohren des Lochs durch die Deckplatte 3 verwendeten Bohrers sein (nicht dargestellt).Cover plate 3 sunk. The locking lugs 8 are sprung on an inner side of the cover plate 3 to the outside and engage behind the cover plate 3 on the inside. The connecting fitting 6 is thereby axially fixed in the cover plate 3 and rotatable. The other end of the connecting fitting 6 engages in the countersink on the inside of the other cover plate 4 of the hollow plate 1 a. The connecting fitting 6 is thereby held at its two ends form fit in the cover plates 3, 4 of the hollow plate 1 against loads in the radial direction. He can thus absorb high forces acting in the space between the two cover plates 3, 4 of the hollow plate 1 in the plate plane. The hollow plate 1 with the inserted into it and in both cover plates 3, 4 radially supported by form-fitting connection fitting 6 forms an assembly 11 according to the invention. The locking lugs 8 form the rear grip elements, which engage behind a cover plate 3 of the hollow plate 1 on the inside. The countersink on the inside of the other cover plate 4 of the hollow plate 1 need not necessarily be cylindrical, for example, it may be tapered corresponding to a tip of a drill used for drilling the hole through the cover plate 3 (not shown).
Der Verbindungsbeschlag 6 ist als Spannexzenter ausgebildet. Er weist ein Einführloch 12 in seiner Umfangswand zum Einbringen eines Kopfs 13 eines Zugankers 14 in radialer Richtung in den Innenraum des rohrförmigen Verbindungsbeschlags 6 auf. VomThe connecting fitting 6 is designed as a clamping eccentric. It has an insertion hole 12 in its peripheral wall for introducing a head 13 of a tie rod 14 in the radial direction in the interior of the tubular connection fitting 6. from
Einführloch 12 verläuft ein Schlitz über etwa 180° in Umfangsrichtung des Verbindungsbeschlags 6. Eine Wandstärke des Verbindungsbeschlags 6 vergrößert sich vom Einführloch 12 ausgehend in einer Verlaufsrichtung des Schlitzes, d.h. der Schlitz wird in Umfangsrichtung tiefer. Durch Drehung des Verbindungsbeschlags 6 um etwa 180° wird der Zuganker 14 an seinem Kopf 13 tiefer in den als Spannexzenter ausgebildeten Verbindungsbeschlag 6 hineingezogen und spannt dadurch die Hohlplatte 1 mit ihrem Rand gegen die andere Platte 2. Solche Spannexzenter sind an sich bekannt und sollen deswegen hier nicht weiter erläutert werden. Der Zuganker 14 ist beispielsweise mittels eines Dübels 15 in der anderen Platte 2 verankert. Mit Figur 1 übereinstimmende Bauteile sind in Figuren 2 und 3 mit gleichen Bezugszahlen bezeichnet. Zur nachfolgenden Erläuterung der Figuren 2 und 3 werden im Wesentlichen die Unterschiede zu Figur 1 dargelegt und es wird ergänzend auf die Ausführungen zu Figur 1 verwiesen.An insertion hole 12 extends a slot over about 180 ° in the circumferential direction of the connection fitting 6. A wall thickness of the connection fitting 6 increases from the insertion hole 12, starting in a direction of the slot, ie the slot is deeper in the circumferential direction. By rotation of the connecting fitting 6 by about 180 °, the tie rod 14 is pulled deeper at his head 13 in the trained as clamping eccentric connecting fitting 6 and thereby biases the hollow plate 1 with its edge against the other plate 2. Such clamping eccentric are known and should therefore will not be explained further here. The tie rod 14 is anchored, for example by means of a dowel 15 in the other plate 2. Parts corresponding to FIG. 1 are designated in FIGS. 2 and 3 by the same reference numerals. For the following explanation of FIGS. 2 and 3, the differences to FIG. 1 are essentially explained and reference is additionally made to the statements relating to FIG.

Im offenen Ende des einen Teils 16 des Verbindungsbeschlags 6 ist das zweite Teil 17 verrastet. Zur Verrastung ist das zweite Teil 17 mit einer umlaufenden Verzahnung 18 versehen, die mit einer komplementären Innenverzahnung des einen Teils 16 in Eingriff steht. Das andere Teil 17 ist zylinderkappenförmig. Mit der umlaufenden Verzahnung, die ein tieferes Einbringen des anderen Teils 17 in das eine Teil 16 des Verbindungsbeschlags 6 und damit eine Längenanpassung des Verbindungsbeschlags 6 an eine Dicke der Hohlplatte 1 ermöglicht, ist der Verbindungsbeschlag 6 teleskopierbar.The connecting fitting 6 shown in Figure 2 is in two parts, its one part 16 substantially corresponds to the connecting fitting 6 of Figure 1. In the open end of a part 16 of the connecting fitting 6, the second part 17 is locked. For locking the second part 17 is provided with a circumferential toothing 18 which is in engagement with a complementary internal toothing of the one part 16. The other part 17 is cylindrical cap-shaped. With the peripheral toothing, which allows a deeper insertion of the other part 17 in the one part 16 of the connecting fitting 6 and thus a length adjustment of the connecting fitting 6 to a thickness of the hollow plate 1, the connecting fitting 6 is telescopic.
