Description

Spannschloß für Schneeketten Die Erfindung bezieht sich auf ein Spannschloß für Schneeketten, bestehend aus hakenförmig gebogenen Gliedern, die mit den inneren Enden an einem durch einen ein-#teckbaren Schlüssel um die Mittelachse verdrehbaren Mittelstück angelenkt sind und mit den äußeren Enden die Endglieder der zu spannenden Kette fassen, wobei die hakenförinigen Glieder durch die Drehbewegung hemmende Mittel in der Schließlage gehalten werden. -Erfindungsgemäß ist nun die Anordnung derart getroffen, daß beide hakenförmige Glieder durch je eine an .diesen unter Spannung anliegende Feder unmittelbar entgegen den das Ausschwingen der Glieder hervorrufenden Kräften belastet =sind.Turnbuckle for Snow Chains The invention relates to a turnbuckle for snow chains, consisting of hook-shaped curved links that connect with the inner Ends of a key that can be rotated around the central axis using an insertable key Central piece are hinged and with the outer ends the end links of the to be clamped Grasp chain, the hook-shaped links by the rotary movement inhibiting means be held in the closed position. According to the invention, the arrangement is like this made that both hook-shaped links are under tension by one on each adjacent spring directly opposed to the swinging of the limbs causing Forces = are loaded.

Die Zeichnung zeigt ein Spannschloß gemäß der Erfindung in Schließlage bei abgehobener Deckplatte des Mittelstuckes.The drawing shows a turnbuckle according to the invention in the closed position with the cover plate of the middle piece lifted off.

Die hakenförmigen Glieder i, 2 sind in bekannter `'eise finit dein lenkerartigen Mitte1-stück j mittels der Bolzen 6, 7 gelenkig verbunden. Das Mittelstück 5 weist die übliche Offnung ä auf, in welche in bekannter Weise ein flacher Schlüssel zum Schließen und Offnen des Schlosses eingeführt werden kann. Die .beiden Glieder i, = traben nun gemäß der Erfindung je einen Ansatz g, Io, gegen welche ;die Blattfedern Ii, 12 wirken, welche in das gehäuseartig ausgebildete Mittelstück 5 unter Spannung eingelegt sind und an den Gelenkbolzen 6, ; anliegen.The hook-shaped links i, 2 are known to be finite Handlebar-like middle 1-piece j connected in an articulated manner by means of bolts 6, 7. The middle piece 5 has the usual opening - in which, in a known manner, a flat key can be inserted to close and open the lock. The two links i, = now trot, according to the invention, a respective approach g, Io, against which; the leaf springs Ii, 12 act, which in the housing-like formed center piece 5 under tension are inserted and on the hinge pin 6,; issue.

Die Sicherung gegen ungewolltes Öffnen des Schlosses wird dadurch erreicht, daß einem Ausschwingen des Gliedes i in der Pfeilrichtung a durch die Einwirkung de r , Fliehkraft bei spannungslos gewordenerKette durch den auf den Fortsatz g des Gegengliedes 2 wirkenden Druck der Blattfeder 12 entgegengewirkt wird, da hierdurch eine Mitdrehung dies Mittelstückes um den Anlenkungsbolz:en 6 und ein das öffnen <las Spannschlosses bewirkendes Ausschwingen desselben verhindert wird.The protection against unintentional opening of the lock is thereby achieved that a swinging of the member i in the direction of arrow a by the Effect of the centrifugal force when the chain has become tensionless by the Extension g of the counter member 2 acting pressure of the leaf spring 12 counteracted because this causes the middle piece to rotate around the pivot bolt: en 6 and prevents the turnbuckle from swinging out, causing it to open will.

Wird jedoch auch hei gespannter Kette der Schlüssel in die Öffnung 8 eingeführt und "edreht, so wird der Widerstand der Blattfedern Ii, Ia überwunden und das Schloß ,geöffnet. Um ein leichtes Offnen des Schlosses mittels des Schlüssels zu sichern, sind die hakenförmigen Glieder i, 2 derart formt und bemessen, daß die Innenkante des einen Gliedes niemals in die Bewegungsbahn irgendeines Punktes des Gegengliedes fallen kann.However, the key is also inserted into the opening with the chain under tension 8 and "rotated", the resistance of the leaf springs Ii, Ia is overcome and the lock, open. To easily open the lock using the key to secure, the hook-shaped members i, 2 are shaped and dimensioned such that the The inner edge of one link should never be in the trajectory of any point of the Opposite link can fall.
