Description

Bez, Breslau.Bez, Wroclaw.

Gegenstand der Erfindung ist ein Vorsteckbolzen, der in seiner Gebrauchslage durch eine Spreizfeder gesichert wird. Es sind Vorsteckbolzen bekannt, welche nach dem Einstecken durch sich selbsttätig spreizende Federn gehalten werden. Bei diesen läßt sich der Bolzen ohne Zerstörung der Feder nicht wieder herausziehen. Anderseits gibt es Vorsteckbolzen, deren Spreizfeder nur mittels eines besonderen Schlüssels zusammengepreßt ^rden kann, oder die durch Anziehen einer besonderen Mutter gesichert werden. Beides ist in den weitaus meisten Fällen unbequem.The invention relates to a locking bolt that is in its position of use by a Spreading spring is secured. There are locking bolts known, which after insertion be held by automatically expanding springs. With these, the bolt Do not pull it out again without destroying the spring. On the other hand there are locking bolts, whose expanding spring can only be compressed using a special key can, or which can be secured by tightening a special nut. Both are in inconvenient in the vast majority of cases.

Der Bolzen nach vorliegender Erfindung soll die genannten Nachteile beseitigen. Er kennzeichnet sich dadurch, daß die Enden der am Bolzen befestigten Spreizfeder in Nuten des Bolzens liegenbleiben und daß sich zwischen den Federenden und der Federbefestigung ein Federbauch befindet, der sowohl den Bolzen gegen unbeabsichtigtes Lösen sichert als auch ein Herausdrehen des Bolzens bei einer gewissen Kraftaufwendung ohne ein besonderes Werkzeug gestattet und ohne weiteres eine beliebig häufige Wiederbenutzung des Bolzens ermöglicht.The bolt according to the present invention is intended to eliminate the disadvantages mentioned. He is characterized in that the ends of the expanding spring attached to the bolt are in grooves of the bolt and that are between the spring ends and the spring fastening a spring belly is located, which both secures the bolt against unintentional loosening and unscrewing the bolt with a certain amount of force permitted without a special tool and without further ado allows the bolt to be reused as often as required.

In der Zeichnung ist die Erfindung dargestellt. The invention is shown in the drawing.

In der Achsbuchse 1 sind Bohrungen 2 für den Bolzen 3. in dessen Schaft 4 sich Nuten 5 befinden, in denen' die Federn. 6, durch Niete 7 gehalten, liegen. Die Nuten 5 sind zweckmäßig nach dem Kopfende des Schaftes zu vertieft. Wird der Bolzen in das Loch eiltgeschoben, so drücken sich die Federn 6 zusammen und spreizen, sich dann wieder auseinander, indem sie auf diese Weise den Bolzen sichern.In the axle bushing 1 there are bores 2 for the bolt 3. In the shaft 4 of which there are grooves 5 are located in which 'the springs. 6, through Rivet 7 held, lie. The grooves 5 are expediently after the head end of the shaft too deepened. If the bolt is pushed into the hole in a hurry, the springs 6 compress and then spread them apart again by doing the bolt to back up.

Die Zahl der Federn ist beliebig. Es genügt unter Umständen eine einzige Feder zur Sicherung, die auch beliebig mit dem Bolzen durch Schrauben usw. verbunden werden kann. Entsprechend Abb. 2 können die Federn auch aus einem Stück bestehen und durch das geschlitzte Ende des Bolzenschaftes 4 fassen, wo sie dann durch ein einziges Niet 9 festgehalten werden.The number of springs is arbitrary. A single spring may be sufficient Fuse that can also be connected to the bolt with screws, etc. at will. According to Fig. 2, the springs can also consist of one piece and through the slotted Grasp the end of the bolt shank 4, where it is then held in place by a single rivet 9 will.
