KLASSE 77h. GRUPPE 7.CLASS 77h. GROUP 7.
Es sind Spanten für Flugzeuge bekannt, be- j stehend aus einem Obergurt und Untergurt und aus diese Gurte verbindenden Zwischengliedern in einer solchen Anordnung, daß entsprechend der Verbiegung des Spants die beiden Gurte gegeneinander verschoben werden können. Zu diesem Zweck sind die Verbindungsglieder beispielsweise als starre, zweiarmige Hebel ausgebildet, an deren einem ArmThere are known frames for aircraft, consisting of an upper chord and a lower chord and from intermediate links connecting these belts in such an arrangement that accordingly the bending of the frame, the two straps can be moved against each other. For this purpose are the connecting links for example designed as a rigid, two-armed lever, on one arm
ίο der Untergurt, am anderen Arm der Obergurt befestigt ist, derart, daß durch Schrägstellen dieses Hebels vom Führersitz aus die Verschiebung der Gurte stattfindet.ίο the lower chord, on the other arm the upper chord is attached in such a way that the shift by tilting this lever from the driver's seat the belt takes place.
Die Federung dieser Spanten wird lediglich durch die Elastizität der beiden Gurte bewirkt. Demgegenüber betrifft die vorliegende Erfindung ein Spant, dessen Federung neben der Elastizität der Gurte vor allem durch die Elastizität der Zwischenstücke bewirkt wird, die, zwischen den beiden Gurten eingeschaltet, gleichzeitig deren Verbindung bewirken.The suspension of these ribs is only caused by the elasticity of the two belts. In contrast, the present invention relates to a frame, the suspension in addition to the elasticity of the belts is mainly caused by the elasticity of the intermediate pieces, which, switched on between the two belts, simultaneously effect their connection.
Fünf Ausführungsbeispiele der Erfindung sind auf der Zeichnung in sechs Figuren dargestellt. Five exemplary embodiments of the invention are shown in the drawing in six figures.
Fig. ι und 2 zeigen ein Spant von der Seite und von oben gesehen, während die übrigen Figuren andere Ausführungsformen der elastischen Zwischenglieder darstellen.Fig. Ι and 2 show a frame seen from the side and from above, while the rest Figures represent other embodiments of the elastic intermediate members.
In den Figuren sind 1 der Obergurt, 2 der Untergurt des Spants, 3 Querträger. Das Spant hat, soweit es zwischen den Querträgern fest eingespannt ist, in üblicher Weise einen festen Steg 4, während die Gurte an den freien elastischen Enden durch federnde Zwischenglieder 5 verbunden sind. Die Zwischenglieder haben bei der ersten Ausführungsform wellenförmige, rechteckartig, bei der letzten Ausführungsform wellenförmige, dreieckartig zusammengesetzte Gestalt. Bei der Ausführungsform nach Fig. 3 und 4 sind sie als geschlossene Ringe von rundem oder viereckigem Querschnitt ausgebildet, während sie bei der Ausführungsform nach Fig. 5 Z-förmigen Querschnitt besitzen.In the figures, 1 is the top flange, 2 is the bottom flange of the frame, and 3 is the cross member. That As far as it is firmly clamped between the crossbeams, the frame has one in the usual way fixed web 4, while the belts at the free elastic ends by resilient intermediate links 5 are connected. The intermediate links have in the first embodiment wave-shaped, rectangular-shaped, in the last Embodiment wavy, triangular compound shape. In the embodiment of FIGS. 3 and 4, they are as closed Rings formed with a round or square cross-section, while in the embodiment according to FIG. 5 they have a Z-shaped cross-section own.
