Description

Sicherungsvorrichtung für den Kupplungsbolzen von Anhängerkupplungen an Kraftfahrzeugen. Die vorliegende Erfindung hat eine Verbesserung an jenen Sicherungsvorrichtungen für den Kupplungsbolzen von Anhängerkupplungen an Kraftwagen zum Gegenstand, bei welchen der Bolzen unter dem Einfluß von Schraubenfedern in seinen Endstellungen gesichert ist. Gegenüber den bekannten Einrichtungen dieser Art, hei . welchen die Schließstellung durch die Schraubenfedern bewirkt wirr und bei denen daher zum Entkuppeln eine verhältnismäßig große Kraft zur Cberwindung .der Federspannung erforderlich ist, bezweckt die Erfindung, die Sicherung durch starre Glieder zu bewirken und nach Lösen derselben die Entkupplung durch Federn zu erleichtern.Safety device for the coupling bolt of trailer hitches on motor vehicles. The present invention has an improvement on those security devices for the coupling bolt of trailer hitches on motor vehicles which the bolt under the influence of coil springs in its end positions is secured. Compared to the known facilities of this type, he. which the The closed position by the coil springs causes confused and which therefore decouples a relatively large force to overcome the spring tension required is, the invention aims to effect the securing by rigid members and after loosening the same to facilitate the decoupling by springs.

Dies wird dadurch erreicht, daßeine zum Verschieben des Kupplungsbolzens in die obere Endstellung dienende Schraubenfeder angeordnet ist und zum Bewegen des Kupplungsbolzens in die untere Endstellung ein an dem Kupplungsbolzen und an der Kupplungsgabel angreifender Hebelverschluß dient.This is achieved by having one for sliding the coupling bolt is arranged in the upper end serving helical spring and to move of the coupling pin in the lower end position on the coupling pin and on the clutch fork attacking lever lock is used.

Eine solche Sicherungsvorrichtung für den Kupplungsbolzen von Anhängerkupplungen an Kraftfahrzeugen ist. in den Abb. i und z der Zeichnung in einem Ausführungsbeispiel dargestellt, wobei .die Abb. i den lotrechten Längsschnitt nach der Linie <d-B der Abb. 2 und diese eine Stirnansicht der Abb. i zeigt.Such a safety device for the coupling pin of trailer hitches on motor vehicles. in Figs. i and z of the drawing in one embodiment shown, with .die Fig. i the vertical longitudinal section along the line <d-B of Fig. 2 and this shows an end view of Fig. i.

Der Kupplungskörper i ist mit Bohrungen 3 der beiden Augen da, db um die Querstange 2 drehbar gelagert. In dem ,der Zugstange 5 zugekehrten Teile ,des Kupplungskörpers i ist eine Ouerausnehmung 6 für die Aufnahme der Ose 511 vorgesehen, welche von iclem die oberen und unteren Plattenteile des Kupplungskörpers in Bohrungen durchdringenden Kupplungsbolzen 7 festgehalten wird. Dieser besitzt einen Bund 7a, gegen welchen sich das obere Ende einer Schraubenfeder 8 anlegt, fieren unteres Ende sich gegen den Kupplungskörper r .stützt. Am Kopfe des Kupplungsbolzens 7 ist ein Kniehebelverschluß g aasgelenkt; dessen Zughebel ga Bügelform he= sitzt und in einen am Kupplungskörper befestigten Haken i o einhängb,ar ist. Durch .Niederdrücken des Griffhebels i i wird auch fier Kupplungsbolzen 7 entgegen der Wirkung der Schraubenfeiler 8 nach unten gepreßt und in seiner Lage festgehalten, während beim Hochklappen des Griffhebels die Feder 8 derart entspannt wird, daß der Zughebel ga aus dein Haken io ausgehängt -werden kann, worauf der Bolzen 7 nach oben aus dem Kupplungskörper heraushebbar ist. Statt der Kniehebelbefestigun:g könnte natürlich ebensogut eine andere, .den Bolzen unter Zug oder Druck festhaltende Vorrichtung vorgesehen sein.The coupling body i is there with holes 3 of the two eyes, db rotatably mounted around the crossbar 2. In the parts facing the pull rod 5 , of the coupling body i an Ouerausbreak 6 is provided for receiving the eyelet 511, which of iclem the upper and lower plate parts of the coupling body in bores penetrating coupling bolt 7 is held. This has a collar 7a, against which the upper end of a helical spring 8 rests, fieren lower End is supported against the coupling body r. At the head of the coupling pin 7 is a toggle lock g aasgecke; whose pull lever ga bow shape he = sits and hooked into a hook i o attached to the coupling body, ar is. By pressing down the handle lever i i is also fier coupling bolt 7 against the action of the screw piles 8 pressed down and held in place while folding up the Lever the spring 8 is relaxed so that the pull lever ga out of your hook io can be unhooked, whereupon the bolt 7 upwards out of the coupling body can be lifted out. Instead of the toggle lever attachment, one could of course just as well be other, .the bolt under tension or pressure retaining device may be provided.
