Abstract

The invention relates to a towing device which operates automatically, is intended for motor vehicles and has a removable ball-ended rod. A pin, which under spring loading can move upwards and downwards in vertical grooves, is pretensioned by a lever and on insertion of the ball-ended rod is brought, by the lever being released, into a locking position in which it latches into a groove on the ball-ended rod.

Description

Die Erfindung betrifft eine Anhängezugvorrichtung mit abnehmbarer Kugelstange für KFZ. Bei den bisher eingesetzten Konstruktionen werden federbelastete Verriegelungsbolzen mit axialer Bewegung verwendet. Da die Federn relativ stark sein müssen, ist der benötigte Konstruktions­ raum entsprechend groß. Zudem trägt der Bolzen nur einseitig. Er muß also entsprechend dick ausgeführt werden. Der Erfinder hat es sich zur Aufgabe gemacht, diese Nachteile zu eliminieren. Er schlägt vor, im festen Teil gegenüberliegende senkrechte Nuten im hinteren Bereich der Einsteckbohrung für die Kugelstange anzuordnen, in dem sich ein federbelasteter Bolzen auf- und abbewegt.The invention relates to a towing device with removable Ball bar for cars. With the constructions used so far spring-loaded locking bolt with axial movement used. There the springs must be relatively strong is the construction required room accordingly large. In addition, the bolt is only on one side. So he has to be made accordingly thick. It is the task of the inventor made to eliminate these disadvantages. He suggests in the fixed part opposite vertical grooves in the rear area of the insertion hole to be arranged for the ball rod in which a spring-loaded bolt and moved away.

Bei der Kugelstange fehlt am hinteren Ende im oberen Bereich ein Stück, ungefähr ein Halbzylinder. In dem verbleibenden Stück ist eine nach oben offene Nut. Am festen Teil ist ein Hebel, der den federbelasteten Bolzen anzuheben erlaubt. Durch Herunterdrücken des Hebels wird der Bolzen in die obere Lage gebracht. Der Hebel wird in dieser Lage durch eine Sperre festgehalten. An der Kugelstange ist ein Gegenelement. Sobald beim Ein­ führen der Kugelstange dieses die Sperre wegdrückt, und dies geschieht zu dem Zeitpunkt an dem die nach oben offene Nut sich direkt unter den feder­ belasteten Bolzen befindet, springt dieser in diese Nut der Kugelstange und arretiert sie.The ball rod is missing a piece at the rear end in the upper area, about a half cylinder. In the remaining piece there is one up open groove. On the fixed part is a lever that holds the spring-loaded bolt allowed to lift. By pushing the lever down, the bolt is in brought the top layer. The lever is locked in this position captured. There is a counter element on the ball rod. As soon as on guide the ball rod this pushes the lock away, and this happens to the moment when the upwardly open groove is directly under the tongue loaded bolt, it jumps into this groove in the ball rod and locks them.

Fig. 1+2 zeigen perspektivisch den festen Teil 1 und den losen Teil 2, also die abnehmbare Kugelstange. Durch den Auslösehebel 3 wird der Bolzen 4, der sich in am festen Teil befindlichen gegenüberliegenden senkrechten Nuten 14 befindet, hochgedrückt. Die Sperre 5 hält den Hebel 4 und damit den Bolzen 4 hoch. Das Kugelstangenende kann mit seinem Ausschnitt 6 unter den Bolzen 4 gleiten. Die Sperre 5 wird durch den an der Kugelstange befestigten Auslöser 7 weggedrückt und der Hebel 3 kann sich durch die Federkraft der Feder 8 um den Punkt 9 drehen. Der Bolzen 4 gleitet in den Ausschnitt 6. Die Kugelstange hat am Ende einen weiteren Ausschnitt 10, in dem der Bolzen 11, der im festen Gehäuse sitzt, sich im Auslösemoment be­ findet. So ist der feste Teil gegen Herausziehen und Drehen gesichert. Die Sperre 12 setzt sich nach dem Einrasten unter den Hebel 3 und arretiert denselben. Da die Gabel 13 den Bolzen 4 einschließt, ist derselbe ebenfalls gegen Herausspringen gesichert. Diese Konstruktion ist sehr sicher, da zum Zeitpunkt des Auslösens des Hebels 3 und damit des Bolzens 4 die Kugelstange in der Position ist, in der mit Sicherheit der Bolzen 4 in die Nut 6 der Kugelstange einrastet. Fig. 1 + 2 show in perspective the fixed part 1 and the loose part 2, that is, the detachable ball rod. By the release lever 3 , the bolt 4 , which is located in the opposite vertical grooves 14 located on the fixed part, is pushed up. The lock 5 holds the lever 4 and thus the bolt 4 up. The cutout 6 of the ball rod end can slide under the bolts 4 . The lock 5 is pushed away by the trigger 7 attached to the ball rod and the lever 3 can rotate about the point 9 by the spring force of the spring 8 . The bolt 4 slides into the cutout 6 . The ball rod has at the end a further cutout 10 in which the bolt 11 , which is seated in the fixed housing, can be found at the triggering moment. So the fixed part is secured against pulling out and turning. After locking, the lock 12 sits under the lever 3 and locks it. Since the fork 13 includes the bolt 4 , the same is also secured against jumping out. This construction is very safe, since at the time the lever 3 and thus the bolt 4 are triggered, the ball rod is in the position in which the bolt 4 will certainly snap into the groove 6 of the ball rod.
