Description

Laie seit Jahren bekannte Flachfederung, deren 1?nden auf der einen Seite eines Holzrahmens drehbar und auf der anderen Seite verschielabär gelagert sind, 'hat den Nachteil, daß die allein auf der Rachen Wölbung beruhende Federkraft ibei hoher Beanspruchung und bei Verwendung langer Federn nicht dauerhaft ist.Flat suspension known to laypeople for years, whose 1 ?nds on the one hand Side of a wooden frame rotatable and mounted on the other side in a different way are, 'has the disadvantage that the spring force, which is based solely on the curvature of the pharynx i is not durable under high stress and when using long springs.

Laie nachstehend beschriebene l#--rtin.duiig beseitigt diesen Mangel auf höchst einfache Weise 'und erweitert damit den Anwendungsbereich der Federung erheblich.Layman described below l # - rtin.duiig eliminates this deficiency in a very simple way 'and thus extends the scope of the suspension considerable.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt, und zwar zeigt Abb. i die Flachfeder mit Zugfeder im Aufriß und :\b1>.2 die Flachfeder mit Zugfeder im Grundriß. Die in Abb. i gezeigte Flachfeder a wird auf leiden Seiten vor der letzten Windung mit einem Spezialhaken b zusammengehalten, dessen Mittelstück zu einem Auge ausgebildet ist (Abb. 2). An embodiment is shown in the drawing, namely Fig. I shows the flat spring with tension spring in elevation and: \ b1> .2 the flat spring with tension spring in elevation. The flat spring a shown in Fig. I is held together on some sides before the last turn with a special hook b, the middle piece of which is designed as an eye (Fig. 2).

Die !beiden Haken b werden in Längsrichtung der Flachfeder a durch einfache 1)rahthafken c sowie einer Zugfeder d aus Stahldraht verbunden. Die Anspannung der Zugfeder beträgt etwa too/o der jeweiligen Entfernung von Haken zu Haken b.The! Two hooks b are through in the longitudinal direction of the flat spring a simple 1) rahthafken c and a tension spring d made of steel wire. The tension the tension spring is about too / o the respective distance from hook to hook b.

Bei Belastung der Flachfeder a wird durch das Niederdrücken der Wölbung (-1b. i) die Entfernung zwischen den beiden Haken b vergrößert @utid somit die bereits unter Spannung stehende Zugfeder d zusätzlich gespannt. Dadurch wird eine starke Gegenfederung bewirkt, die das Bestreben hat, die Flachfeder a in ihre Ausgangsstellung zurückzuziehen.When the flat spring a is loaded, the curvature is depressed (-1b. I) the distance between the two hooks b increases @utid the already tension spring d under tension is additionally tensioned. This makes a strong one Counter-springing causes the tendency to move the flat spring a into its starting position to withdraw.

Die ,beschriebene Flachfeder a kann durch diesen Gegendruck erheblich mehr belastet werden. Insbesondere läßt sich auf diese Weise eine sehr wirkungsvolle Rückenfederung im Fahrzeugbau sowie eine stabile Unterfederung für große Sitz- und Liegemöbel erzielen.The flat spring a described can be considerably due to this counter pressure to be burdened more. In particular, a very effective one can be achieved in this way Back suspension in vehicle construction as well as a stable base suspension for large seats and Achieve lounge furniture.
