Description

TECHNISCHES GEBIETTECHNICAL AREA

Die Erfindung betrifft das Gebiet der Möbel, insbesondere Tische mit anklappbaren Beinen.The invention relates to the field of furniture, in particular tables with folding legs.

STAND DER TECHNIKSTATE OF THE ART

Es sind unterschiedliche technische Lösungen für Tische bekannt, deren Beine anklappbar sind. Solche Tische sind wichtig insbesondere im kommerziellen Bereich, wo in flexibler Weise Räume möbliert werden müssen. Dabei müssen die Möbel, auch die Tische, einerseits einfach und schnell aufgestellt werden, andererseits müssen sie aber auch einfach wieder abgebaut und auf möglichst kleinem Raum gelagert werden.There are known different technical solutions for tables whose legs are hinged. Such tables are particularly important in the commercial sector, where rooms must be furnished in a flexible manner. The furniture, including the tables, on the one hand must be set up quickly and easily, but on the other hand, they must also be easily dismantled and stored in the smallest possible space.

Selbstverständlich ist es dabei auch erforderlich, dass die Möbel sowohl im aufgestellten Zustand als auch bei der Lagerung stabil sind, und auch ein ästhetisch ansprechendes Erscheinungsbild haben, aber dennoch nur geringes Gewicht aufweisen und möglichst kostengünstig bei der Herstellung sind. Ferner soll das Aufstellen und Lagern möglichst schnell und einfach auch von Nicht-Fachkräften vorgenommen werden können.Of course, it is also necessary that the furniture is stable both in the erect condition and during storage, and also have an aesthetically pleasing appearance, but still have low weight and are as inexpensive as possible in the production. Furthermore, the setting up and storage as quickly and easily as possible by non-professionals can be made.

Eine Konstruktion zum Befestigen eines anklappbaren Beines an einem Möbelstück ist bekannt zum Beispiel aus EP 1 050 240 A1 . Die dort beschriebene Konstruktion ist aufwändig und kompliziert und illustriert eindrücklich, welche Anstrengungen unternommen werden, um die vorgenannten Anforderungen zu erfüllen.A construction for attaching a hinged leg to a piece of furniture is known, for example EP 1 050 240 A1 , The design described there is complex and complicated and illustrates impressively, which efforts are made to meet the aforementioned requirements.

Ein anderer Tisch mit anklappbaren Beinen ist bekannt aus US Patent 5,490467 . Die Beine sind an der Unterseite der Tischplatte längs verschiebbar gelagert. Streben sind einerseits an den Beinstandrohren, und andererseits an der Unterseite der Tischplatte angelenkt. Eine das die Beinstandrohre verbindende Beinlagerrohr durchtretende Stange gleitet mit ihren Enden in einer Nut. In aufgestellter Position werden diese Enden mittels einer Verschlussnocke fixiert, die manuell lösbar ist.Another table with folding legs is known from U.S. Patent 5,490,467 , The legs are mounted longitudinally displaceable on the underside of the table top. Struts are hinged on the one hand to the Beinstandrohren, and on the other hand at the bottom of the table top. A rod passing through the Beinstand tubes connecting rod slides with its ends in a groove. In an erected position, these ends are fixed by means of a locking cam, which is manually detachable.

Ein weiterer Tisch mit anklappbaren Beinen ist bekannt aus US Patent 5,109,778 . Auch hier sind die Beine an der Unterseite der Tischplatte längs verschiebbar gelagert, und sind Streben einerseits an den Beinstandrohren und andererseits an der Unterseite der Tischplatte angelenkt. Ein das T-förmige Beinstandrohr tragendes Beinlagerrohr gleitet mit seinen beiden Enden in einer Nut, und im aufgestellten Zustand wird das Beinlagerrohr lösbar verriegelt.Another table with folding legs is known from U.S. Patent 5,109,778 , Again, the legs are mounted longitudinally displaceable on the underside of the table top, and struts are articulated on the one hand to the Beinstandrohren and on the other hand on the underside of the table top. A Beinlagerrohr carrying the T-shaped Beinstandrohr slides with its two ends in a groove, and in the erected state, the Beinlagerrohr is releasably locked.

Schließlich ist ein Tisch mit anklappbaren Beinen noch aus US Patent 3,291,078 bekannt. Wiederum sind die Beine an der Unterseite der Tischplatte längs verschiebbar gelagert, und sind Streben vorgesehen, die einerseits an den Beinen, und andererseits an der Tisch-Unterseite angelenkt sind. Ein Verschlussglied bewirkt, dass die Beine im angeklappten Zustand unter der Tischplatte fixiert sind.Finally, a table with folding legs is still off U.S. Patent 3,291,078 known. Again, the legs are mounted longitudinally displaceable on the underside of the table top, and struts are provided, which are hinged on the one hand to the legs, and on the other hand to the underside of the table. A closure member causes the legs are fixed in the folded state under the table top.

Die bisher bekannten Tische erfüllen jedoch die oben genannten anspruchsvollen Anforderungen gar nicht oder bestenfalls nur unvollkommen, weil die Fixiermechanismen kompliziert und wenig robust sind. Es ist daher noch immer ein großes Problem, Tische dahingehend zu verbessern, dass sie den oben genannten Anforderungen möglichst weitgehend gerecht werden.However, the previously known tables do not meet the above demanding requirements or at best only imperfectly, because the fixing mechanisms are complicated and not very robust. It is therefore still a big problem to improve tables to the extent that they meet the above requirements as much as possible.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Es ist daher die Aufgabe der Erfindung, einen Tisch mit anklappbaren Beinen dahingehend zu verbessern, dass einerseits

  • die Beine einfach anklappbar und aufstellbar sind, und
  • der Tisch im aufgestellten Zustand einen stabilen Stand hat, aber dennoch
  • ein ästhetisch ansprechendes Erscheinungsbild abgibt, und
  • der Tisch im gelagerten Zustand nur wenig Raum einnimmt, insbesondere beim Stapeln in die Höhe,
dass aber andererseits
  • der Herstellungsaufwand und damit die Produktionskosten möglichst klein sind.
It is therefore the object of the invention to improve a table with folding legs to the effect that on the one hand
  • the legs are easy to fold and set up, and
  • The table has a stable state when set up, but still
  • gives an aesthetically pleasing appearance, and
  • the table occupies little space in the stored state, especially when stacking in the air,
that on the other hand
  • the manufacturing costs and thus the production costs are as small as possible.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 und der Unteransprüche gelöst.This object is solved by the features of claim 1 and the dependent claims.

Kern der Erfindung ist die Idee, die Verschiebeführung für das Bein im Lagerkörper unter der Tischplatte als Nut mit einer Ausnehmung nach oben auszugestalten, in welcher der Lagerzapfen des Beinlagerrohrs gleitet und einrastet, und auf einem nach oben weisenden schiefen Steg eine Arretierkugel rollen zu lassen, die bei aufgestelltem Tisch unter den Lagerzapfen rollt und diesen in der Ausnehmung fixiert, und bei auf den Rücken gelegtem Tisch vom Lagerzapfen wegrollt und diesen freigibt. Damit wird eine lageabhängige gravitationsgesteuerte Fixierung und Lösung der Beine erreicht, und es entfallen damit andernfalls notwendige Maßnahmen und Elemente, wie z.B. Flügelmuttern, die jeweils gelöst und wieder festgeschraubt werden müssen, oder komplexe Schnappmechanismen.The essence of the invention is the idea to design the sliding guide for the leg in the bearing body under the table top as a groove with a recess upwards, in which the bearing pin of the Beinlagerrohrs slides and locks, and to let roll on a roll-up angled upward locking ball, which rolls when the table is under the bearing journals and fixes them in the recess, and when the table is laid on its back, it rolls away from the journal and releases it. Thus, a position-dependent gravitation-controlled fixation and solution of the legs is achieved, and it eliminates the otherwise necessary measures and elements, such as wing nuts, which must be solved in each case and tightened again, or complex snap mechanisms.

These pairs of legs except the Beinstandrohren 4 still each have the Beinlagerrohr 3 and the Fußquerrohr. 5

Im oberen Drittel ist zwischen den Beinstandrohren 4 jeweils ein Querriegel 8 vorgesehen, an welchem mittels der Verbindungsschrauben 23 gelenkig eine Strebe 6 gelagert ist. Die Strebe 6 ist als Drahtbügel geformt. Der Querriegel 8 verhindert das Herausdrehen des Drahtbügels aus den Bohrungen im Beinstandrohr 4.In the upper third, a cross bar 8 is provided between the Beinstandrohren 4, to which by means of the connecting screws 23 articulated a strut 6 is mounted. The strut 6 is shaped as a wire bow. The cross bar 8 prevents unscrewing of the wire bracket from the holes in Beinstandrohr. 4

Das andere Ende der Strebe 6 ist gelenkig an einem Strebenlager 7 unter der Tischplatte 1 befestigt. Das Strebenlager 7 ist an der Tischplatte 1 mittels Schrauben 21 befestigt, und weist zwei sich gegenüberstehende, elastische, aus Kunststoff bestehende Klemmnasen 27 auf.The other end of the strut 6 is hinged to a strut bearing 7 under the table top 1. The strut bearing 7 is on the table top 1 means Fixed screws 21, and has two opposing, elastic, existing plastic clamping noses 27.

Ein aus dem Kunststoff ABS bestehender Kantenschutz 2 schützt die Tischplatte 1, eine aus Filz bestehende Stapelauflage 10 schützt beim Stapeln der zusammengelegten Tische.An edge protection 2 consisting of the plastic ABS protects the table top 1, a stack support 10 consisting of felt protects the stacked tables during stacking.

Die beiden Beinlagerrohre 3 sind mit ihren Enden in den Lagerkörpern 11 längsverschiebbar gelagert. Diese Lagerkörper 11 sind Winkeleisen aus Stahl, die mit ihrer einen Fläche mit den Befestigungsschrauben 20 an der Unterseite der Tischplatte 1 angeschraubt sind, und in deren anderer Fläche eine Nut 24 mit zur Tischplatte gerichteter Ausnehmung 25 vorgesehen ist. Mit den Lagerkörpern 11 ist über die Verbindungsschrauben 22 das Gehäuse 9 verbunden.The two leg bearing tubes 3 are mounted with their ends in the bearing bodies 11 so as to be longitudinally displaceable. This bearing body 11 are angle iron made of steel, which are screwed with its one surface with the mounting screws 20 on the underside of the table top 1, and in the other surface a groove 24 is provided with directed towards the table top recess 25. With the bearing bodies 11, the housing 9 is connected via the connecting screws 22.

In Fig. 2 ist gezeigt, dass die Beinlagerrohre 3 an ihren Enden Lagerzapfen 15 aufweisen, die im Beinlagerrohr 3 mittels eines aus Kunststoff bestehenden Rohreinsatzes 16 fixiert sind. Dieser Rohreinsatz 16 besteht aus dem Kunststoff PA6 mit 30% Glasfasern.In Fig. 2 It is shown that the leg bearing tubes 3 have at their ends journals 15 which are fixed in the leg bearing tube 3 by means of a pipe insert 16 made of plastic. This tube insert 16 consists of the plastic PA6 with 30% glass fibers.

Außerdem ist in Fig. 2 zu sehen, dass an den beiden Enden des Fußquerrohres 5 Fußgleiter 17 vorgesehen sind, die mittels der Befestigungsschrauben 19 am Fußquerrohr 5 angeschraubt sind. In dem Fußgleiter 17 ist ein Gewinde vorgesehen, in dem eine Fußgleiterschraube 18 höheneinstellbar eingeschraubt ist. Der Fußgleiter 17 besteht aus dem Kunststoff PA6 mit 15% Glasfaser, die Fußgleiterschraube 18 aus Stahl oder PA6.It is also in Fig. 2 to see that 5 foot sliders 17 are provided at the two ends of the Fußquerrohres, which are screwed by means of the mounting screws 19 on the cross-section 5. In the Fußgleiter 17 a thread is provided, in which a Fußgleiterschraube 18 is screwed height adjustable. The Fußgleiter 17 consists of the plastic PA6 with 15% glass fiber, the Fußgleiterschraube 18 steel or PA6.

In Fig.3 ist die Führung des Lagerzapfens 15 eines Beinlagerrohres 3 im Einzelnen dargestellt:In Figure 3 the guide of the journal 15 of a leg bearing tube 3 is shown in detail:

Im Bild ist der Lagerzapfen 15 in der Ausnehmung 25 der Nut 24 im Lagerkörper 11 eingerastet. Das Beinstandrohr 4 ist also aufgestellt. Wenn das Beinstandrohr 4 angeklappt wird, bewegt sich der Lagerzapfen 15 aus der Ausnehmung 25 heraus und in der Nut 24 bis zu deren Ende. Dabei bremst die Feder 13 den Anschlag des Lagerzapfens 15 am Ende der Nut 24 ab.In the picture, the bearing pin 15 is engaged in the recess 25 of the groove 24 in the bearing body 11. The leg stand tube 4 is thus set up. When the leg stand tube 4 is folded, the bearing pin 15 moves out of the recess 25 out and in the groove 24 to the end. The spring 13 brakes the stop of the bearing pin 15 at the end of the groove 24.

In Fig. 3 ist des weiteren gezeigt, dass unter dem Lagerzapfen 15 eine Feder 12 liegt, und unter dieser Feder 12 eine Kugel 14. Diese Kugel 14 kann sich auf dem schiefen Steg 26 bewegen. Das Gehäuse 9 besteht aus dem Kunststoff PA6 mit 30% Glasfaser. Der Steg 26 ist in das Gehäuse 9 eingeformt. Eingeformt sind auch die Halterungen für die Arretierfeder 12 und die Bremsfeder 13.In Fig. 3 is further shown that under the bearing pin 15, a spring 12 is located, and under this spring 12, a ball 14. This ball 14 can move on the inclined web 26. The housing 9 is made of the plastic PA6 with 30% glass fiber. The web 26 is formed in the housing 9. Also formed are the brackets for the locking spring 12 and the brake spring thirteenth

In Fig. 4 ist ein Schnitt durch das Lager des Lagerzapfens 15 dargestellt.In Fig. 4 a section through the bearing of the journal 15 is shown.

In Fig. 5 ist der Rohreinsatz 16 dargestellt. Dieser ist als innen konischer Hohlzylinder ausgebildet, wobei die Neigung des Konusmantels etwa 2° beträgt. Am Kopf weist der Rohreinsatz 16 am Umfang außen gegenüber dem Innendurchmesser des Beinlagerrohres 3 ein Übermaß auf, an seinem unteren Ende ein Untermaß. Der Mantel des Rohreinsatzes 16 weist Schlitze 28 und Rippen 29 auf. Damit kann der Rohreinsatz 16 in das Beinlagerrohr 3 eingeschlagen werden, und verklemmt sich darin. Danach wird der Lagerzapfen 15 eingeschlagen, und verklemmt sich in dem Rohreinsatz 16 unter Aufspreizung des Mantels. Der Konuswinkel von 2° bewirkt, dass einerseits der Reibungswiderstand beim Einschlagen des Lagerzapfens 15 nicht zu groß ist, andererseits ein einmal eingeführter Zapfen 15 nicht herausfällt.In Fig. 5 the tube insert 16 is shown. This is designed as an internally conical hollow cylinder, wherein the inclination of the cone shell is about 2 °. At the top, the tube insert 16 on the circumference on the outside with respect to the inner diameter of the leg bearing tube 3 an excess, at its lower end an undersize. The jacket of the tube insert 16 has slots 28 and ribs 29. Thus, the tube insert 16 can be hammered into the leg bearing tube 3, and jammed in it. Thereafter, the bearing pin 15 is taken, and clamped in the tube insert 16 under spreading of the shell. The cone angle of 2 ° causes on the one hand, the frictional resistance when driving the journal 15 is not too large, on the other hand, a once introduced pin 15 does not fall out.

In Fig. 6 ist schließlich der Fußgleiter 17 im Einzelnen dargestellt. Im Gegensatz zum bekannten Stand der Technik kann die Fußgleiterschraube 18 durch Verdrehen in der Höhe eingestellt werden, und leicht ausgewechselt werden, zum Beispiel für unterschiedliche Bodenbeläge.In Fig. 6 Finally, the Fußgleiter 17 is shown in detail. In contrast to the known prior art, the Fußgleiterschraube 18 can be adjusted by turning in height, and easily replaced, for example, for different floor coverings.

Die Funktion des erfindungsgemäßen Tisches ist wie folgt:The function of the table according to the invention is as follows:

Wenn der aus den Beinstandrohren 4 bestehende T-Fuß an die Tischplatte 1 angeklappt wird, so rotiert der T-Fuß um das Lager der Strebe 6 am Querriegel 8, und die Lagerzapfen 15 verschieben sich in der Nut 24 des Lagerkörpers 11 bis zum Anschlag. Die Beinstandrohre 4 rasten dann in die Klemmnasen 27 am Strebenlager 7 ein.When the existing from the Beinstandrohren 4 T-foot is folded onto the table top 1, the T-foot rotates about the bearing of the strut 6 on the cross bar 8, and the bearing pin 15 move in the groove 24 of the bearing body 11 to to the stop. The Beinstandrohre 4 then engage in the clamping lugs 27 on the strut bearing 7 a.

Wenn der Tisch aufgestellt ist, nimmt der Lagerzapfen 15 die in der Fig. 3 gezeigte Position in der Ausnehmung 25 der Nut 24 ein. Dabei blockiert die Arretierkugel 14 den Lagerzapfen 15 in der Ausnehmung 25. Der T-Fuß ist also stabil fixiert. Die Fixierung bzw. Stabilisierung des Tisches erfolgt zusätzlich über das Eigengewicht bzw. die Belastung der Tischplatte 1.When the table is set up, the trunnion 15 takes in the Fig. 3 shown position in the recess 25 of the groove 24 a. The locking ball 14 blocks the bearing pin 15 in the recess 25. The T-foot is thus fixed stable. The fixation or stabilization of the table takes place additionally on the weight or the load of the table top. 1

Wenn der Tisch auf den Rücken gelegt wird, und auf das Beinstandrohr 4 eine Kraft zum Anklappen ausgeübt wird, rollt die Arretierkugel 14 auf dem schiefen Steg 26 in Richtung Tischplatte 1 und gibt den Lagerzapfen 15 frei, sodass er sich in der Nut 24 seitwärts bewegen kann.When the table is placed on the back and the leg stand pipe 4 is subjected to a folding force, the locking ball 14 rolls on the inclined land 26 toward the table top 1 and releases the bearing pin 15 so as to move laterally in the groove 24 can.
