Description
Spannschloßsicherung für den Luftfahrzeugbau Es ist bereits vorgeschlagen worden, Spannschlösser gegen unbeabsichtigtes Lösen durch in Längsschlitzen der Spannmutter verschiebbare und unter Federdruck stehende Sicherungsble:che zu sichern, die in Verriegelungsstellung in die Enden der Spannschrauben eingreifen. Bei diesen Sicherungen müssen zum jeweiligen Lösen und Anziehen der Spannschrauben die Sicherungsschieber von Hand aus dem Eingriff mit den Spannschrauben gebracht werden.Turnbuckle safety device for aircraft construction It has already been proposed been, turnbuckles against unintentional loosening through in longitudinal slots of the Locking nut to secure sliding locking plates under spring pressure, which engage in the locking position in the ends of the tensioning screws. With these The safety slides must be used to loosen and tighten the tensioning screws be brought out of engagement with the tensioning screws by hand.
Gemäß der Erfindung wird das bislang vor dem Anziehen der Spannschrauben erforderliche Lösen der Sicherung von Hand dadurch vermieden, daß die Spannschrauben nach Art einer Klauenrutschkupplung an der Stirnseite mit schrägen Zähnen versehen sind. Diese Zähne bilden Gleittlächen für die Sicherungsble.che derart, daß diese beim Spannen des Spannschlosses über die Gleitflächen hinweggleiten, d. h. das Spannen des Spannsch1,osses nicht behindern, während sie ein unbeabsichtigtes Entspannen des Spannschlosses nach wie vor nicht zulassen. Bei der rechtsgängigen Spannschraube des Spannschlosses verlaufen die schrägen Zähne oder Gleitflächen in umgekehrter Richtung wie bei der linksgängigen Spannschraube.According to the invention, this has so far been done before the tightening of the clamping screws required loosening of the safety device by hand avoided that the tensioning screws Provided with oblique teeth on the front side in the manner of a claw slip clutch are. These teeth form sliding surfaces for the locking plates in such a way that these slide over the sliding surfaces when tensioning the turnbuckle, d. H. the tensioning of the Spannsch1, osses not hinder, while it is an unintentional relaxation still not allow the turnbuckle. With the right-hand tensioning screw of the turnbuckle, the inclined teeth or sliding surfaces run in reverse Direction as with the left-hand tensioning screw.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigt Abb. i einen Längsschnitt durch ein Spannschloß :mit der erfindungsgemäßen Sicherung, Abb. a eine Seitenansicht.An exemplary embodiment of the invention is shown in the drawing. It shows Fig. I a longitudinal section through a turnbuckle: with the inventive Fuse, Fig. A is a side view.
Es bezeichnet a eine Spannmutter mit Längsschlitzen b, die entweder etwa die ganze Länge der Sp,annmuttera einnehmen oder aber zur Vermeidung einer zu starken Schwächung des Spannmutterkörpers durch ein als Sechskant ausgebildetes Mittelstücke unterbrochen sind. d sind die Spannschrauben, in deren Enden e unter dem Druck' einer Feder/ stehende Sicherungsbleche g eingreifen. Die Sicheru.ngsbl@ech:e g besitzen umgelegte Lappen lt, die sie in den Längsschlitzen b der Spannmutter a gegen Herausfallen sichern und gleichzeitig als Handgriffe zur Verschiebung der Bleche o- dienen. Die Stirnseiten der Spannschrauben ,d sind nach Art einer Klauenrutschkupplung mit schrägen Zähnen oder Gleitflächen i versehen, die im Drehsinne des anzuziehenden Spanns-cblosses verlaufen. Wird das Spa:nnschloß a angezogen, so gleiten die Sicherungsbleche g auf den Gleitflächen i und hindern die Verstellung des Schlossesa nicht. Soll das. Spannschloß a gelöst werden, so müssen zunächst die Sicherungsbleche g von Hand aus zurückgeschoben werden, da sie in der Verriegelungsstellung eine Drehung der Spannschrauben d im Sinne eines Lösens des Spannschlosses a nicht zulassen.It denotes a clamping nut with longitudinal slots b, which either occupy approximately the entire length of the Sp, annmuta or are interrupted by a hexagonal center piece to avoid excessive weakening of the clamping nut body. d are the tensioning screws, in whose ends e engage under the pressure of a spring / standing locking plates g. The Sicherheitsu.ngsbl@ech: eg have folded flaps that secure them against falling out in the longitudinal slots b of the clamping nut a and at the same time serve as handles to move the sheets. The end faces of the tensioning screws, d are provided with inclined teeth or sliding surfaces i in the manner of a claw slip clutch, which run in the direction of rotation of the tensioning lock to be tightened. If the spa lock a is tightened, the locking plates g slide on the sliding surfaces i and do not prevent the lock a from being adjusted. If the turnbuckle a is to be released, the locking plates g must first be pushed back by hand, since in the locked position they do not allow a rotation of the tensioning screws d in the sense of loosening the turnbuckle a.
