Abstract
Description
Die Erfindung betrifft einen Karabinerhaken mit einem durch einen am Schaft des Hakenkörpers geführten, federbelasteten Schieber verschließbaren Hakenmaul und einer mit dem Hakenschaft drehbar verbundenen Ringöse.The invention relates to a snap hook with a hook mouth which can be closed by a spring-loaded slide guided on the shaft of the hook body and a ring eyelet rotatably connected to the hook shaft.
Derartige Karabinerhaken, deren Hakenmaul mit einem federbelasteten Verschlußbolzen verschlossen ist, werden häufig in Verbindung mit galvanisierten Ketten oder dergleichen verwendet, deren letztes Kettenglied mit der Ringöse verbunden wird. Kette und Hakenkörper bestehen dabei in der Regel aus unterschiedlichen Metallegierungen, so daß sie nicht miteinander galvanisierbar sind. Der Hakenkörper ist in der Regel ein Gußteil, beispielsweise aus einem Zink-Druckguß. Die Kettenglieder bestehen aus geschmiedetem Material.Such snap hooks, the hook mouth of which is closed with a spring-loaded locking bolt, are often used in connection with galvanized chains or the like, the last chain link of which is connected to the eyelet. The chain and hook body usually consist of different metal alloys, so that they cannot be galvanized together. The hook body is usually a casting, for example from a die-cast zinc. The chain links are made of forged material.
Nach der Galvanisierung der Einzelteile erfolgt die Montage.After the galvanizing of the individual parts, assembly takes place.
der/ Bekannt ist ein Karabinerhaken, bei der federbelastete Verschlußbolzen in einer seitlich geführten Längsbohrung im Hakenschaft geführt ist. Die Bohrung ist dabei nach außen durch eine eingesprengte Platte verschlossen, an der sich die Druckfeder abstützt. Die Ringöse ist von außen auf dem zylindrischen Hakenschaft drehbar aufgesetzt und mit einem Kragen an der Öse gehalten, der in eine Ringnut am Hakenschaft eingreift.A carabiner is known, in which spring-loaded locking bolts are guided in a laterally guided longitudinal bore in the hook shaft. The bore is closed to the outside by an injected plate on which the compression spring is supported. The ring eyelet is rotatably mounted on the outside of the cylindrical hook shaft and held with a collar on the eye which engages in an annular groove on the hook shaft.
In dem eigentlichen Hakenkörper sind für die Aufnahme und die Führung des Verschlußbolzens eine Bohrung und ein seitlicher Schlitz anzubringen, außerdem ist am Ende des Schaftes die Ringnut auszubilden. Die Anfertigung des Hakenkörpers ist daher aufwendig. In entsprechende im Gußverfahren oder als Stanzteil hergestellte Hakenkörper sind daher mit nachgeschalteten Bearbeitungsvorgängen de entsprechenden Aufnahmen und Führungen vorzusehen.In the actual hook body, a hole and a side slot are to be made for receiving and guiding the locking bolt, and the annular groove is also to be formed at the end of the shaft. The preparation of the hook body is therefore complex. Corresponding hook bodies manufactured in the casting process or as a stamped part are therefore to be provided with subsequent machining operations de corresponding receptacles and guides.
Die Aufgabe der Erfindung besteht darin, einen Karabinerhaken der eingangs genannten Art in seiner Herstellung zu vereinfachen, wobei eine Bearbeitung bzw. Beeinträchtigung der bereits galvanisierten Einzelteile bei der Montage vermieden werden soll.The object of the invention is to simplify the manufacture of a snap hook of the type mentioned at the outset, with machining or Impairment of the already galvanized individual parts should be avoided during assembly.
Zur Lösung der Erfindungsaufgabe ist ein solcher Karabinerhaken gekennzeichnet durch einen parallel zur Hakenebene geteilten Hakenkörper, zwischen dessen spiegelsymmetrischen, miteinander verbundenen Körperhälften sowohl der Verschlußschieber als auch der Verbindungsbolzen der Ringöse gehalten sind.To achieve the object of the invention, such a snap hook is characterized by a hook body divided parallel to the hook plane, between the mirror-symmetrical, interconnected body halves of which both the locking slide and the connecting bolt of the eyelet are held.
Nach einer bevorzugten Ausführungsart der Erfindung greift der in einer Bohrung im Hakenschaft entgegen dem Druck einer Feder geführte zylindrische Verschlußschieber im Verschlußzustand in eine stirnseitige Bohrung am Hakenende ein. Die Ringöse kann dabei mit dem Kopf eines an der Öse befestigten Bolzens drehbar in einer zwischen den Körperhälften gebildeten nutartigen Hinterschneidung drehbar gehalten sein.According to a preferred embodiment of the invention, the cylindrical locking slide, which is guided in a bore in the hook shaft against the pressure of a spring, engages in an end-side bore on the hook end in the locked state. The eyelet can be rotatably held with the head of a bolt attached to the eyelet in a groove-like undercut formed between the body halves.
Aufgrund der spiegelsymmetrischen Zweiteilupg des Hakenkörpers lassen sich die Körperhälften in günstiger Weise als Press - oder Gußteile herstellen, wobei die notwendigen Ausnehmungen im Inneren des Hakenkörpers bereits mit eingeformt werden können. Nach der Galvanisierung der Einzelteile werden die zwischen den beiden Körperhälften einzusetzenden Teile, nämlich der federbelastete Verschlußschieber und der Verbindungsbolzen der Ringöse, eingelegt. Die Verbindung der beiden Körperhälften kann beispielsweise durch Vernietung oder Verschweißung erfolgen. Die Montage des Karabinerhakens ist dadurch äußerst einfach.Because of the mirror-symmetrical two-part part of the hook body, the body halves can be produced in a favorable manner as pressed or cast parts, the necessary recesses in the interior of the hook body already being able to be formed. After the galva Nization of the individual parts, the parts to be used between the two body halves, namely the spring-loaded locking slide and the connecting bolt of the eyelet, are inserted. The two halves of the body can be connected, for example, by riveting or welding. The assembly of the snap hook is extremely easy.
