Patentirt im Deutschen Reiche vom 16. April 188a ab.Patented in the German Empire on April 16, 188a.

Bei dem Gebrauch der gewöhnlichen Karabinerhaken durch die Feuerwehrleute ist es nicht selten, dafs infolge falschen Schlingens des Seiles der Karabinerhakenverschlufs geöffnet wird, das Seil aus dem Haken gleitet und die betreffende Person in Gefahr kommt, herabzustürzen. Diesen Uebelstand der Karabinerhaken zu beseitigen, bezweckt die in Fig. 1 bis 4 dargestellte Verschlufsconstruction. Dieser Verschlufs kann sich nie durch das Seil oder einen unbewufsten Griff öffnen, sondern es ist zur Oeffnung stets nöthig, dafs der Versc.hlufsriegel zurückgeschoben wird.When firefighters use ordinary snap hooks, it is not seldom that the snap hook lock was opened as a result of incorrect looping of the rope the rope slips out of the hook and the person concerned is in danger of falling off. The purpose of the one shown in FIGS. 1 to 4 is to eliminate this disadvantage of the snap hooks Enclosure construction. This lock can never get through the rope or one open unconscious grip, but it is always necessary to open the locking mechanism is pushed back.

Das Federgelenk, welches durch die Feder F gedrückt wird, trägt in seinem Innern den Riegel R. Letzterer ist in der Ausbohrung geführt und hat einen Ansatz b, um welchen die Feder f gewunden ist, die sich bei c gegen die abgesetzte Ausbohrung stützt und infolge dessen den Riegel R stets vorwärts treibt, wobei letzterer mit seinem vorderen Ende in die Bohrung C des Hakenbügels H eingreift und ein Oeffnen des Federmechanismus nicht ohne weiteres zuläfst. Es mufs für den letzteren Fall der Riegel mittelst besonderen Mechanismus zurückgeschoben werden, was wie folgt geschieht. Der Riegel R ist an seinem Ende mit dem Schlitz s versehen, in welchen der Schenkel r des Winkelhebels eingreift. Der Schenkel h des Winkelhebels ist mit dem Druckstift c so verbunden, dafs beim Niederdrücken von e eine Rückwärtsbewegung des ' Riegels R erfolgen mufs und somit das Oeffnen des Federgelenkes bewirkt wird.The spring joint, which is pressed by the spring F , carries the bolt R in its interior. The latter is guided in the bore and has a shoulder b, around which the spring f is wound, which is supported at c against the offset bore and as a result whose front end always drives the bolt R forward, the front end of which engages in the bore C of the hook bracket H and does not allow the spring mechanism to open easily. In the latter case, the bolt must be pushed back by means of a special mechanism, which is done as follows. The bolt R is provided at its end with the slot s , in which the leg r of the angle lever engages. The leg h of the angle lever is connected to the pressure pin c in such a way that when e is depressed, a backward movement of the bolt R must take place and thus the opening of the spring joint is effected.
