Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 149360. Federungseinrichtung für Polstermöbel. Gegenstand der vorliegenden Erfindung ist eine weitere Ausbildung der im Patentan spruch des Hauptpatentes gekennzeichneten Federungseinrichtung.
Nach der Erfindung ist das vermittelst Federn in der Öffnung des Tragrahmens nach giebig, aber straff gespannt gehaltene Unter lagestück mit im Abstand nebeneinander an geordneten Verstärkungseinlagen versehen.
Auf der beiliegenden Zeichnung ist der Erfindungsgegenstand in einer beispielsweisen Ausführungsform dargestellt, und es zeigt von derselben Fig. 1 eine Unteransicht, und Fig. 2 einen Schnitt nach der Linie I-11 der Fig. 1, Fig. 3 einen Schnitt nach der Linie II-III der Fig. 1 in grösserem Massstab.
1 bezeichnet einen Holzrahmen, an dessen Abstufung 2 vermittelst Nägeln 3 der nach giebige Deckrahmen 4 angeordnet ist. An den Innenecken der Abstufung 2 sind Zweispitz- Bogennägel 5 eingetrieben, in welche die Schraubenfedern 6 eingehängt sind, welche das Unterlagsstück 7 tragen. Letzteres be sitzt in den Rändern Ösen B. durch welche die innern Enden der Federn 6 führen. Das Unterlagestück besteht aus Stoff und ist nachgiebig, aber straff vermittelst der Federn 6 angespannt.
Das Unterlagestück besitzt zwei übereinanderliegende Stofflagen und in durch Nähte 9 gebildeten Taschen 10 desselben, die in einem Abstand, der dem doppelten Feder abstand entspricht, nebeneinanderliegen, sind aus Federstahl bestehende Verstärkungsbän- der 11 angeordnet.
In den Stirnenden der letzteren befinden sich, in Übereinstimmung mit einem Teil der Ösen des Unterlagestük- kes, ebenfalls Ösen 8, in welche die entspre chenden, mit den Verstärkungsbändern in einer Linie liegenden Federn 6 mit ihrem in- nern Ende eingreifen. Die obere Stofflage ist an den Seiten noch mit einem die untere Lage übergreifenden Saum 12 versehen.
Die beschriebene Federungseinrichtung gewährleistet eine gleichmäP)ige Unterlage für Auflegepolster, welche nicht beschädigt werden können, und erhalten die Aufliege- teile keinerlei Eindrücke. Die Verstärkungs bänder 11 gewährleisten eine gleichmässigere Verteilung der Beanspruchungen auf die Fe dern ö und damit der vier Zargen des Holz rahmens 1.

In the accompanying drawing, the subject matter of the invention is shown in an exemplary embodiment, and FIG. 1 shows a bottom view of the same, and FIG. 2 shows a section along the line I-11 of FIG. 1, FIG. 3 shows a section along the line II -III of Fig. 1 on a larger scale.
1 denotes a wooden frame, at the gradation 2 by means of nails 3 the cover frame 4 is arranged according to the yielding. Two-pointed bow nails 5 are driven into the inner corners of the gradation 2, into which the helical springs 6, which carry the washer 7, are suspended. The latter be sitting in the edges eyelets B. through which the inner ends of the springs 6 lead. The base piece is made of fabric and is flexible but taut by means of the springs 6.
The base piece has two layers of fabric lying one on top of the other and in pockets 10 of the same formed by seams 9, which are located next to one another at a distance corresponding to twice the spring spacing, reinforcing strips 11 made of spring steel are arranged.
In the front ends of the latter, there are also eyelets 8, in correspondence with some of the eyelets of the base piece, in which the corresponding springs 6, which are in line with the reinforcement bands, engage with their inner ends. The upper layer of fabric is also provided on the sides with a hem 12 that overlaps the lower layer.
The suspension device described ensures a uniform base for the cushions, which cannot be damaged, and the support parts do not receive any impressions. The reinforcing strips 11 ensure a more even distribution of the stresses on the springs ö and thus the four frames of the wooden frame 1.
