Description
Der Neuerung liegt die klare Erkenntnis und Beseitigung dieses Mangels
zugrunde. Gemäß der Neuerung sind in den Armstützen elastisehe Elemente angeordnet,
welche nach Maßgabe der Belastung der Rückenlehne zusammengepresst werden und deren
Rückstellkraft die Rückenlehne entsprechend der Entlastung derselben in Richtung
der oder in die Ausgangslage zurückführen.
Hierbei erfolgt die kraftschlüssige Verbindung über je einen Beschlag, welcher mit der Rückenlehne fest verbunden ist. Jeder Beschlag weist ein abgekröpftes Ende auf, welches mit den Gummikörpern in kraft-und formschlüssiger Verbindung steht. Here, the force-fit connection is made via one fitting each, which is firmly connected to the backrest. Each fitting has a cranked one End, which is in force-locking and form-locking connection with the rubber bodies.
Vorteilhaft sind die Gummikörper keilförmig ausgebildet, wenngleich die Neuerung auf diese besondere Ausbildungsform keineswegs beschränkt ist. The rubber bodies are advantageously wedge-shaped, albeit the innovation is by no means limited to this particular form of training.
Die Neuerung ist nachstehend anhand der Zeichnung noch etwas ausführlicher erläutert. Diese läßt eine Teilansicht einer Armstütze eines Stuhles sowie eine Rückenlehne gemäß der Neuerung deutlich erkennen. The innovation is a little more detailed below based on the drawing explained. This leaves a partial view of an armrest of a chair as well as one Clearly recognize the backrest according to the innovation.
Mit 1 ist ein Teil einer gewölbten Armstütze eines Stuhles bezeichnet. In der Wölbung der Armstütze ist zweckmäßig ein sichelförmige Einsatzstück 2 aus glasfaserverstärktem Polyester vorgesehen. With 1 part of a curved armrest of a chair is referred to. A sickle-shaped insert 2 is expediently made in the curvature of the armrest glass fiber reinforced polyester provided.
Mit 3 ist ein Teil der Rückenlehne bezeichnet, mit welcher zu beiden Seiten je ein Beschlag 4 fest verbunden ist. Die Verbindung erfolgt hierbei mittels Schrauben, Nägeln od. dgl. With 3 a part of the backrest is referred to, with which to both Each side a fitting 4 is firmly connected. The connection is made using Screws, nails or the like.
Der Beschlag 4 weist ein nach aussen abgekröpfte Ende 4a auf, das in eine Aussparung 2a des Einsatzstückes 2 eingreift. The fitting 4 has an outwardly bent end 4a which engages in a recess 2a of the insert 2.
Zu beiden Seiten des abgekröpften Endes 4 a des Beschlages 4 sind elastische Elemente in Form von Gummikörpern 5, 6 so gelagert, daß ersterermit diesen Gummikörpern 5, 6 in kraft-und formschlüssiger Verbindung steht. Zweckmäßig sind diese Gummikörper 5, 6 keilförmig ausgebildet, wobei die Keilspitzen in entgegengesetzer Richtung weisen.On both sides of the bent end 4 a of the fitting 4 are elastic elements in the form of rubber bodies 5, 6 mounted in such a way that the former is in a force-locking and form-locking connection with these rubber bodies 5, 6. These rubber bodies 5, 6 are expediently wedge-shaped, with the wedge tips point in the opposite direction.
Wird die Rückenlehne 3 des Stunes belastet, dann werden die Gummikörper 5,6 zusammengedrückt, was das Auftreten von Reaktionskräften zur Folge hat, welche dem Ausschwenken der Rückenlehne 3 entgegengesetzt gerichtet sind. Dadurch wird ein übermässiges Ausschwenken der Rückenlehne 3 und damit ein Überkippen des Stuhlbenutzers nach hinten mit Sicherheit vermieden. Die Rückenlehne 3wird somit stets eine ganz bestimmte Grenzstellung einnehmen, welche von der Größe der Belastung der ersteren abhängt. If the backrest 3 of the stune is loaded, then the rubber body 5,6 compressed, which results in the occurrence of reaction forces, which the pivoting of the backrest 3 are directed in the opposite direction. This will excessive pivoting of the backrest 3 and thus tipping over of the chair user definitely avoided to the rear. The backrest 3 is thus always a whole assume a certain limit position, which depends on the magnitude of the burden of the former depends.
Wird die Rückenlehne 3 hingegen entlastet, dann sind die Rückstellkräfte der Gummifederkörper 5,6 bestrebt, die Rückenlehne 3 in die Ausgangsstellung zurückzuführen. Die Rückstellkräfte der Gummikörper 5,6 üben somit auf die Rückenlehne 3 ein Drehmoment aus, welches dem durch die Belastung hervorgerufenen Moment entgegenwirkt. If the backrest 3 is relieved, however, then the restoring forces the rubber spring body 5, 6 endeavors to return the backrest 3 to the starting position. The restoring forces of the rubber bodies 5, 6 thus exert a torque on the backrest 3 which counteracts the moment caused by the load.
Der Vorteil der Gummikörper 5, 6 ist vor allem darin zu erblicken, daß die elastische Kraft selbst bei langjähriger Benutzung des Stuhles keinerlei Beeinträchtigung erfährt. Dies ist beispielsweise bei Stahlfedern keineswegs der Fall. The main advantage of rubber bodies 5, 6 is that they that the elastic force does not have any effect even after long years of use of the chair Experienced impairment. This is by no means the case with steel springs, for example Case.
