Description
In neuerer Zeit sind für Polster und Matratzen aller Art Federgerüste bekanntgeworden, die aus nebeneinanderliegenden, an den Enden halbkreisförmig gebogenen Blattfedern bestehen. Es hat sich nun gezeigt, daß gerade die gebogenen Enden am stärksten belastet sind und häufig brechen.More recently, spring frames have become known for upholstery and mattresses of all kinds, those made of leaf springs lying next to one another, curved in a semicircle at the ends exist. It has now been shown that it is precisely the bent ends that are most heavily loaded and often break.
Die Erfindung besteht nun darin, daß an der Innenseite jedes Blattfederbogens eineThe invention consists in the fact that on the inside of each leaf spring arch one
ίο Zwischenfeder in Gestalt eines zweiten kleineren Blattfederbogens angebracht ist. Bei Bruch oder starker Belastung der Außenfeder nimmt diese Zwischenfeder den Stoß auf, so daß das Polster in jedem Falle gebrauchsfähig bleibt.ίο Intermediate spring in the form of a second smaller one Leaf spring arch is attached. In the event of breakage or heavy load on the outer spring this intermediate spring on the impact, so that the cushion remains usable in any case.
Der Gegenstand der Erfindung ist in der Zeichnung in einer Ausführungsform im Schnitt dargestellt. Auf dem Federgerüst α liegt das Polsterkissen b. Das Federgerüst besteht aus nebeneinandergelagerten Blattfedern, die anThe object of the invention is shown in the drawing in one embodiment in section. The cushion b lies on the spring frame α. The spring structure consists of leaf springs mounted next to one another, which are attached to
ao den beiden Enden halbkreisförmig gebogen sind. An der Innenseite dieser Bogen sind Zwischenfedern c angebracht, welche die Gestalt kleinerer gebogener Blattfedern besitzen. Wenn sich bei starker Belastung' die äußeren Blattfedern stark zusammendrücken, so kornmen sie zur Berührung mit den Zwischenfedern c. Diese nehmen also die starke Belastung und den Stoß auf. Dasselbe geschieht bei Bruch der äußeren Blattfedern, indem in diesem Falle die Zwischenfedern allein die Belastung aufnehmen und die Federung des Polsters aufrechterhalten.ao the two ends are curved in a semicircle. On the inside of these arches are Intermediate springs c attached, which have the shape of smaller curved leaf springs. If the outer leaf springs compress strongly under heavy load, then they grain they come into contact with the intermediate springs c. So these take the heavy burden and the bump on. The same thing happens if the outer leaf springs break, in that in In this case, the intermediate springs alone absorb the load and the suspension of the Upholstery.
