Description

Wippvorrichtung für Stühle mit Sitzspindel Die vorliegende Erfindung betrifft eine Wippvorrichtung für Stühle mit Sitzspindel und besteht ihrem Wesen nach darin, daß die Sitzträger mittels eines waagerechten Schwenkbolzens an dem einen Ende eines rinnenförmigen, starr auf der Sitzspindel befestigten Tragarmes gelagert sind. Bei Verwendung einer Spannvorrichtung für die Wickelfedern sind diese auf dem Schwingbolzen gelagert und stützen sich mit ihrem Ende gegen den Tragarm ab.Rocking device for chairs with seat spindle The present invention relates to a rocking device for chairs with a seat spindle and consists of its essence after that the seat support by means of a horizontal pivot pin on the one end of a channel-shaped support arm rigidly attached to the seat spindle are stored. When using a tensioning device for the clock springs, these are mounted on the swing bolt and supported with their end against the support arm away.

In der Zeichnung ist eine beispielsweise Ausführungsform des Gegenstandes dargestellt, und zwar zeigt Abb. i einen Längsschnitt durch die Wippvorrichtung, Abb. 2 eine Aufsicht von Abb. i, Abb. 3 einen Querschnitt durch die Wippvorrichtung.In the drawing is an example embodiment of the object shown, namely Fig. i shows a longitudinal section through the rocking device, Fig. 2 is a plan view of Fig. I, Fig. 3 is a cross section through the rocker device.

Das Sitzträgergestell, welches auf den beiden Winkeln L und deren Verbindungsstücken i und h besteht, ist mit dem rinnenförmigen Tragarm a durch den Schwingbolzen e derart verbunden, daß in horizontaler Stellung des Sitzes, also in Ruhestellung, der Tragarm bei f anschlägt und beim Wippen der größte Ausschlag durch den Anschlag f1 begrenzt ist. Die Wickelfedern b ruhen auf dem Rohr d, welches durch den Schwingbolzen e gehalten wird, der den Tragarm a mit dem Sitzträger Z direkt verbindet. Die Schenkel der Federn liegen einerseits im Tragarm a bei der Anlage lc auf, anderseits in der Federspannvorrichtung c, durch welche die Spannung der Federn b beliebig eingestellt und dem Körpergewicht der betreffenden Person angepaßt werden kann, je nachdem, ob das Wippen des Sessels leichter oder schwerer erfolgen soll. Das Oberteil des mit diesem Beschlage ausgestatteten Sessels bleibt in jeder geneigten Stellung stehen und folgt der leisesten Bewegung des Sitzenden nach vorn bzw. hinten. Es wird durch diese Anordnung eine sehr geringe Bauhöhe benötigt, und die Kräfte werden von dem schmiedeeisernen Tragarm a direkt auf die Sitzträger l übertragen. An dem Träger d ist die Sitzspindel in mit der Niethülse ia fest eingenietet.The seat support frame, which consists of the two angles L and their connecting pieces i and h, is connected to the trough-shaped support arm a by the pivot pin e in such a way that in the horizontal position of the seat, i.e. in the rest position, the support arm strikes at f and when rocking the largest deflection is limited by the stop f1. The coil springs b rest on the tube d, which is held by the swing bolt e, which connects the support arm a with the seat support Z directly. The legs of the springs lie on the one hand in the support arm a at the system lc, on the other hand in the spring tensioning device c, through which the tension of the springs b can be adjusted as desired and adapted to the body weight of the person concerned, depending on whether the rocking of the chair is easier or should be more difficult. The upper part of the armchair equipped with this fitting remains in any inclined position and follows the slightest movement of the seated person forwards or backwards. This arrangement requires a very low overall height, and the forces are transmitted from the wrought-iron support arm a directly to the seat support l. The seat spindle is riveted to the rivet sleeve ia firmly on the carrier d.
