Abstract

The device protects a lorry trailer from theft when left parked separately, e.g. when the lorry is away delivering or collecting goods etc. It comprises a bolt inserted in the eye of the trailer towbar, and with a lock in its end. The lock tongue engages in a recess formed in a ring fitted over the bolt end. The lock can be of the cylinder type, its front plate being flush with the end face of the bolt, while the recess can consist of an internal annular groove formed inside the ring. The edges of the ring and bolt head bearing against the eye can be radiused.

Description

Beschreibung: Description:

Die Erfindung bezieht sich auf eine Diebstahlsicherung für LKW-Anhänger. The invention relates to an anti-theft device for truck trailers.

Es kommt häufig vor, daß Kraftfahrer, die einen LKW mit Anhänger fal ren, den Anhänger abkoppeln und parken, während sie mit dem Motorwagen allein Besorgungen erledigen. It often happens that drivers who have a truck with a trailer fold, uncouple the trailer and park while you are alone with the motor vehicle Running errands.

Die geparkten Anhänger werden bisweilen mit @@dung un@@@@@@@@ vom Parkplatz abgefahren, indem sie -an Motorwegen vorr Dieben angekoppelt werden, der dann mit dein gestohlenen Anhänger --om Parkplatz fährt und verschwindet. The parked trailers are sometimes sent with @@ dung un @@@@@@@@ from Drive off the parking lot by coupling them to motorized paths in front of thieves then with your stolen trailer - drives out of the parking lot and disappears.

Der Erfindung liegt die Aufgabe zu Grunde solche Diebstähle zu verhindern. Die Lösung dieser Aufgabe ist ein in die Anhängerdeichselöse einzuschiebender Bolzen, in den ein an der Stirnseite zu betätigendes Schloß eingebaut ist, dessen Zuahltung in einer Aufnahme eines über den Bolzen zu streifenden Ringes eintritt. The invention is based on the object of preventing such thefts. The solution to this task is a bolt to be pushed into the trailer drawbar eye, in which a lock to be operated at the front is installed, the additional payment of which occurs in a receptacle of a ring to be rubbed over the bolt.

Das Schloß ist zweckmäßig ein Zylinderschloss, dessen Frontplatine mit der Bolzenfrontebene bündig ist, so daß es von Werkzeugen wie Rohrzangen nicht ergriffen werden kann. Die Aufnahme der Zuhaltung besteht am besten aus einer im Ringinneren umlaufenden Rille. Dann kann der Ring auch nach Vorschieben der Zuhaltung auf dem Bolzen gedreht, aber nicht achsial abgehoben werden. The lock is expediently a cylinder lock, its front plate flush with the bolt front plane so that tools such as pipe wrenches do not can be seized. The locking mechanism is best made of an im Inner ring circumferential groove. Then the ring can also after advancing the guard locking rotated on the bolt, but not lifted off axially.

Damit dies auch nicht mit Brechstangen oder ähnlichen Werkzeugen geschehen kann, sind die der Deichselöse anstehenden Kanten von Ring und Bolzenkopf gerundet.So that this does not happen with crowbars or similar tools the edges of the ring and bolt head adjacent to the drawbar eye are rounded.

Die Zeichnung zeigt schematisch und im Schnitt ein bevorzugtes Ausführungsbeispiel der Erfindung und zwar ist: i q. 1: ein Querschnitt durch die Sicherung und : in Schnitt nach Linie II-II der Fig. 1.The drawing shows schematically and in section a preferred embodiment of the invention, namely: i q. 1: a cross-section through the fuse and: in Section along line II-II of FIG. 1.

Die Anhängerdeichsel ist in dieser Zeichnung mit 13 bezeichnet.The trailer drawbar is denoted by 13 in this drawing.

iLe endet in einer Öse ci.iLe ends in a loop ci.

Zur Diebstahlsicherung des geparkten Anhängers wird durch die Öse v in Bolzen 2 gesteckt. Uber den aus der Öse 9 herausragenden Teil des Bolzens 2 wird ein Ring 6 gestreift. Der Ring 6 hat innen eine ringsum laufende Nut oder Rille 5, die die Zuhaltung 1 eine in den Bolzen 2 eingebauten Zylinderschlosses 3 aufnimmt.To protect the parked trailer from theft, the eyelet v inserted in bolt 2. Via the part of the bolt 2 protruding from the eyelet 9 a ring 6 is touched. The ring 6 has an all-round groove or groove on the inside 5, which the tumbler 1 receives a cylinder lock 3 built into the bolt 2.

Das Zylinderschloß 3 ist mit einer - nach Überstreifen des Ringes 6 unzugänglichen - Schraube 14 im Bolzen 2 festgelegt. Die Frontplatine 7 des Schloßes 3 ist bündig mit der Frontebene 8 des Bolzens 2 und auch der Vorderfläche 15 des Ringes 6.The cylinder lock 3 is with one - after slipping over the ring 6 inaccessible - screw 14 set in bolt 2. The front plate 7 of the lock 3 is flush with the front plane 8 of the bolt 2 and also the front surface 15 of the Ring 6.

Die der Deichselöse 9 anstehenden Kanten 10 des Bolzenkopfes 12 und 11 des Ringes 6 sind soweit abgerundet, daß sie keine Ansatzstellen für Brechstangen und dgl. bietn.The edges 10 of the bolt head 12 adjacent to the drawbar eye 9 and 11 of the ring 6 are rounded to the extent that they do not have any attachment points for crowbars and the like.
