PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft ein Spannkreuz für Sprungfederpolsterungen aller Art, das in Verbindung mit Ketten, Zugfedern u. dgl., die sonst im allgemeinen gebräuchliche Bindfadenverschnürung und Gurtbefestigung ersetzen soll. Gemäß der Erfindung besteht das Spannkreuz aus zwei miteinander gelenkig verbundenen Blechstreifen, deren Enden zur Aufnahme des letzten Federringes umgebogen ίο sind.The invention relates to a tension cross for spring upholstery of all kinds, which in connection with chains, tension springs and the like, the otherwise commonly used string tying and to replace the belt attachment. According to the invention, the tension cross consists of two hingedly connected Sheet metal strips, the ends of which are bent over to accommodate the last spring washer ίο.
Auf der Zeichnung stelltOn the drawing represents
Fig. ι das Spannkreuz in der Gebrauchslage, Fig. Ι the tension cross in the position of use,
Fig. 2 zusammengelegt vor der Anbringung, undFig. 2 collapsed before attachment, and
Fig. 3 eine mit dem Spannkreuz verbundene Sprungfeder dar.Fig. 3 shows a spring connected to the tension cross.
Das Spannkreuz besteht aus zwei in der Mitte durch einen Niet lose zusammengehaltenen Streifen α aus Bandeisen, deren Enden mit Schlitzen b versehen und umgebogen sind. Diese umgebogenen Enden dienen zur Aufnahme des obersten Sprungfederringes, während die Schlitze dazu bestimmt sind, die Verbindungsfedern c einzuhaken, wodurch gleichzeitig ein Verschieben des Spannkreuzes verhindert wird. Das Spannkreuz wird in der Stellung nach Fig. 1 auf den obersten Federring geschoben und dann auseinandergedrückt. The tension cross consists of two strips α made of steel band, loosely held together in the middle by a rivet, the ends of which are provided with slots b and are bent over. These bent ends serve to accommodate the uppermost spring washer, while the slots are intended to hook the connecting springs c , which at the same time prevents the tension cross from moving. The tensioning cross is pushed onto the uppermost spring ring in the position according to FIG. 1 and then pushed apart.
Der Hauptvorteil der neuen Anordnung liegt, abgesehen von dem leichten Zusammenbau und der bequemen Auswechselbarkeit der Federn, hauptsächlich darin, daß sie jede Art von Sprungfedern, mit geknoteten, gekapselten oder offenen Federenden, zu benutzen gestattet, da der Spannring in jedem Fall das Auseinanderziehen des äußersten Federringes verhindert.The main advantage of the new arrangement is apart from the ease of assembly and the easy interchangeability of the springs, mainly in the fact that they can be of any kind the use of coil springs with knotted, encapsulated or open spring ends is permitted, since the clamping ring prevents the outermost spring ring from being pulled apart in any case.
