Description

Die vorliegende Erfindung betrifft ein Gelenk gemäß dem Oberbegriff des Anspruchs 1 sowie ein klappbares Möbelteil.The present invention relates to a joint according to the preamble of claim 1 and a folding furniture part.

Ein gattungsgemäßes Gelenk ist beispielsweise aus der DE 2 157 179 bekannt. Solche Gelenke werden insbesondere für zusammenklappbare Möbel wie beispielsweise Lattenroste verwendet, um die Transportierbarkeit solcher sperriger Möbelteile zu verbessern. Die beiden Lattenrostteile werden dabei im einfachsten Fall nach dem Transport mit beigepackten Blechwinkeln miteinander verschraubt. Der Einsatz eines Gelenks zur Verbindung der beiden Lattenrostteile scheitert bisher an der mit diesen Gelenken nicht erreichbaren Stabilität der Verbindung der beiden Lattenrostteile, um die ausgestreckten Lattenrostteile auch horizontal stirnseitig stabil aneinander zu halten. Um diese Anforderung zu erfüllen, müsste ein derartiges Gelenk mit einem Drehpunkt unterhalb der Unterkante des Lattenrostes gestaltet werden, was jedoch aufgrund der Einbausituation des Lattenrostes auf einer durchgehenden Auflage eines Bettgestells nicht machbar ist.A generic joint is for example from the DE 2 157 179 known. Such joints are used in particular for collapsible furniture such as slatted frames to improve the transportability of such bulky furniture parts. The two slatted frame parts are bolted together in the simplest case after transport with enclosed sheet metal angles. The use of a joint for the connection of the two slatted floor parts fails so far at the not achievable with these joints stability of the connection of the two slatted frame parts to keep the extended slatted frame parts also horizontally end-to-end stable. To meet this requirement, such a joint would have to be designed with a pivot point below the lower edge of the slatted base, but this is not feasible due to the installation situation of the slatted frame on a continuous support of a bed frame.

Bei dem in der DE 2 157 179 offenbarten Gelenk werden zur Gewährleistung der notwendigen Stabilität des dort offenbarten Gelenks Widerlagerbolzen benötigt, um einen gelenkig angeordneten Hebel des Gelenks abzustützen. Problematisch ist hier außerdem, dass das Gelenk beim Umklappen des an diesem befestigten Lattenrost Gefahr läuft, überstreckt und dabei beschädigt zu werden.In the in the DE 2 157 179 In order to ensure the necessary stability of the joint disclosed therein, abutment bolts are required to support a hinged lever of the joint. The problem here is also that the joint when folding the slatted attached to this grid runs the risk of being overstretched and thereby damaged.

Aufgabe der vorliegenden Erfindung ist es, ein stabiles Gelenk sowie ein klappbares Möbelteil zu schaffen, mit dem auf einfache und kostengünstige Weise eine Überstreckung des Gelenkes verhinderbar ist.Object of the present invention is to provide a stable joint and a hinged furniture part, with a simple and inexpensive way, a hyperextension of the joint can be prevented.

Diese Aufgabe wird durch ein Gelenk mit den Merkmalen des Anspruchs 1 sowie durch ein klappbares Möbelteil mit den Merkmalen des Anspruchs 9 gelöst.This object is achieved by a hinge with the features of claim 1 and by a folding furniture part with the features of claim 9.

Bei dem aus zwei Beschlägen und einer Lasche bestehenden Gelenk, bei dem die Lasche an ihren jeweiligen Enden drehbeweglich mit jeweils einem der Beschläge verbunden ist, weisen die Beschläge erfindungsgemäß im Bereich ihrer in einer gestreckten Position des Gelenks von der Lasche zumindest teilweise überdeckbaren Enden eine aus der Ebene der Lasche heraus stehenden und in der gestreckten Position des Gelenks an der Lasche anliegenden Anschlag auf. Durch diesen Anschlag ist in einfacher Weise ein Überstrecken des Gelenks verhindert. Ein mit solchen Gelenken ausgestattetes klappbares Möbelteil kann so zuverlässig ausgeklappt werden, ohne Gefahr zu laufen, beim Ausklappvorgang die Gelenke zu überstrecken.In the joint consisting of two fittings and a tab in which the tab is rotatably connected at their respective ends with one of the fittings, the fittings according to the invention in the region of their in an extended position of the hinge of the tab at least partially coverable ends on a standing out of the plane of the tab and in the extended position of the joint on the tab abutting stop. By this stop a overstretching of the joint is prevented in a simple manner. A fitted with such joints hinged furniture part can be so reliably unfolded, without running the risk of overstretching the joints during the unfolding process.

Vorteilhafte Ausführungsvarianten der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.

Gemäß einer vorteilhaften Ausführungsvariante sind die Anschläge als gegenüber der Ebene der Lasche angewinkelte Enden der Beschläge ausgebildet. Derartige beispielsweise aus einem Metallblech bestehende Beschläge können so herstellungstechnisch einfach und kostengünstig in die gewünschte Form gebogen werden.According to an advantageous embodiment, the stops are designed as opposite the plane of the tab angled ends of the fittings. Such existing, for example, a metal sheet fittings can be so easily and inexpensively bent manufacturing technology into the desired shape.

Gemäß einer weiteren Ausführungsvariante sind die Lasche und die Beschläge in einer gestreckten Position miteinander arretierbar. Dazu weisen die Lasche und die Beschläge insbesondere Bohrungen auf, die so angeordnet sind, dass jeweils eine Bohrung der Lasche sich mit einer Bohrung in einem der Beschläge in der gestreckten Position des Gelenks überdeckt und das Gelenk in dieser gestreckten Position durch Einstecken eines jeweiligen Sicherheitsstiftes in jeweils einer der Bohrungen der Beschläge und der Lasche arretierbar ist. Dadurch ist das Gelenk in einfachster Weise in der gestreckten Position arretierbar, um so den gestreckten Zustand eines klappbaren Möbelteils wie beispielsweise eines Lattenrostes abzusichern.According to a further embodiment variant, the tab and the fittings can be locked together in an extended position. For this purpose, the tab and the fittings in particular bores, which are arranged so that in each case a hole of the tab overlaps with a bore in one of the fittings in the extended position of the joint and the joint in this extended position by inserting a respective safety pin in one of the holes of the fittings and the tab can be locked in each case. As a result, the joint is locked in the simplest manner in the extended position, so as to secure the stretched state of a folding furniture part such as a slatted base.

Gemäß einer weiteren Ausführungsvariante weist die Lasche eine Aussparung auf, in die die Anschläge in der gestreckten Position des Gelenks eingreifen. Diese Aussparung ist insbesondere u-förmig, wobei die Anschläge in der gestreckten Position des Gelenks an den Seitenwangen dieser u-förmigen Aussparung anliegen. Dadurch kann zusätzlich einem Auseinanderziehen der zwei zueinander klappbaren Möbelteile in der gestreckten Position und damit eine zusätzliche Belastung des Gelenks verhindert werden.According to a further embodiment, the tab has a recess into which engage the stops in the extended position of the joint. This recess is in particular U-shaped, wherein the stops rest in the extended position of the joint on the side cheeks of this U-shaped recess. As a result, in addition to a pulling apart of the two folding furniture parts in the extended position and thus an additional load on the joint can be prevented.

Die Beschläge sind gemäß einer Ausführungsvariante abgewinkelt ausgebildet, wobei der abgewinkelte Teil sich von einer dem Anschlag abgewandten Seite des Beschlages weg erstreckt. Ein derart ausgebildeter Beschlag weist zum einen gegenüber einem ebenfalls denkbaren ebenen Beschlag eine bessere Formsteifigkeit auf und kann so beispielsweise einen Seitenholm eines Lattenrostes zusätzlich untergreifen, was auch die Stabilität der Anordnung des Gelenks an dem klappbaren Möbelteil erhöht.The fittings are formed angled according to a variant, wherein the angled part extends away from a side facing away from the stop of the fitting. Such a trained fitting has a better compared to a likewise conceivable flat fitting Form stiffness and can thus, for example, a side rail of a slatted base also under attack, which also increases the stability of the arrangement of the joint to the folding furniture part.

In den Figuren 1 und 2 ist mit dem Bezugszeichen 7 insgesamt ein als Lattenrost ausgebildetes klappbares Möbelteil bezeichnet, wobei das klappbare Möbelteil 7 ein erstes Klappelement 8 und ein zweites Klappelement 9 aufweist. Die beiden Klappelemente 8, 9 sind dabei über zwei Gelenke 1, die jeweils an Seitenholmen 81, 91 bzw. 82, 92 der Klappelemente 8, 9 befestigt sind, klappbar miteinander verbunden. Die Figur 1 zeigt dabei den Lattenrost 7 im eingeklappten Zustand, in Figur 2 ist der gestreckte, ausgeklappte Zustand gezeigt. Die Gelenke 1 sind dabei jeweils an der Unterkante der jeweiligen Seitenholme 81, 91, 82, 92 befestigt. Auf der Oberkante der Seitenholme 81, 91, 82, 92 liegen die Enden der Latten 83, 93 des Lattenrostes 7 auf.In the FIGS. 1 and 2 is designated by the reference numeral 7 a total formed as a slatted hinged furniture part, wherein the hinged furniture part 7 has a first flap element 8 and a second flap element 9. The two folding elements 8, 9 are connected via two joints 1, which are respectively attached to side rails 81, 91 and 82, 92 of the folding elements 8, 9, hinged together. The FIG. 1 shows the slatted frame 7 in the folded state, in FIG. 2 is the stretched, unfolded state shown. The joints 1 are in each case attached to the lower edge of the respective side rails 81, 91, 82, 92. On the upper edge of the side rails 81, 91, 82, 92, the ends of the slats 83, 93 of the slatted frame 7 are on.

Wie in den Figuren 3, 4, 7 und 8 gezeigt ist, weist die hier gezeigte Ausführungsvariante des erfindungsgemäßen Gelenks 1 zwei Beschläge 2, 3 auf, die an der Innenfläche jeweiliger Seitenholme 81, 82, 91, 92 flach anliegend befestigt sind. Bevorzugt sind die Beschläge 2, 3 mit den Seitenholmen 81, 82, 91, 92 verschraubt. Die Beschläge 2, 3 können plattenförmig ausgebildet sein, bevorzugt sind diese, wie in Figur 13 zu erkennen ist, als Winkelelemente ausgebildet, um den jeweiligen Seitenholm 81, 82, 91, 92 zur Stabilitätsverbesserung der Anordnung zusätzlich von unten zu untergreifen.As in the FIGS. 3, 4 . 7 and 8 is shown, the embodiment shown here variant of the joint 1 according to the invention two fittings 2, 3, which are attached to the inner surface of respective side rails 81, 82, 91, 92 lying flat. Preferably, the fittings 2, 3 with the side rails 81, 82, 91, 92 screwed. The fittings 2, 3 may be plate-shaped, preferably these are as in FIG. 13 can be seen formed as an angle elements to additionally engage under the respective side rail 81, 82, 91, 92 for stability improvement of the arrangement from below.

Zur Ausbildung des Gelenks 1 sind jeweils die Beschläge 2, 3 über eine Lasche 4 drehbeweglich an den Beschlägen 2, 3 miteinander verbunden. Die Lasche 4 ist bevorzugt als flaches Blechteil mit einem Grundkörper 41 ausgebildet. Die Verbindung kann dabei vorzugsweise über eine Nietverbindung erfolgen, für die Bohrungen 27, 37 in den Beschlägen und Bohrungen 43, 44 in der Lasche vorgesehen sind. Eine der Bohrungen 43, 44 der Lasche kann in einer Ausführungsvariante auch als Langloch als Verstellmöglichkeit zum Ausgleich von Toleranzen ausgebildet sein.To form the joint 1, the fittings 2, 3 are each connected to the fittings 2, 3 in a rotatable manner via a lug 4. The tab 4 is preferably formed as a flat sheet metal part with a base body 41. The connection can preferably take place via a rivet connection, are provided for the holes 27, 37 in the fittings and holes 43, 44 in the tab. One of the holes 43, 44 of the tab can be formed in a variant as a slot as adjustment to compensate for tolerances.

Werden die beiden als Lattenrostteile ausgebildeten Klappelemente 8, 9 über die so gebildeten Gelenke zusammengeklappt, liegen die beiden Klappelemente 8, 9 parallel und versetzt übereinander (siehe Figur 1). Die Versetzung der beiden Klappelemente 8, 9 im eingeklappten Zustand entsteht durch die Länge der Lasche 4, die so bemessen ist, dass die beiden Klappelemente 8, 9 im auseinander geklappten, gestreckten Zustand direkt an ihrer Stirnseite aneinander liegen.If the two formed as a slatted frame folding elements 8, 9 folded over the joints thus formed, the two are Folding elements 8, 9 parallel and offset one above the other (see FIG. 1 ). The displacement of the two folding elements 8, 9 in the folded state is formed by the length of the tab 4, which is dimensioned so that the two folding elements 8, 9 in the unfolded, stretched state lie directly on their front side together.
