Description

Ketten-Notglieder, welche zur Verbindung zerrissener Ketten dienen, sind bereits mehrfach bekannt geworden. Indessen besitzen diese entweder den Nachteil, daß sie nicht 5 ohne weiteres, sondern nur unter Zuhilfenahme von Werkzeugen eingesetzt werden können, oder das Notglied' kann, nachdem die Kette in ordnungsmäßiger Weise durch ein neues Glied wiederhergestellt worden ist,Chain emergency links, which are used to connect broken chains, are already multiple known. However, these either have the disadvantage that they are not 5 easily, but only with the aid can be used by tools, or the emergency link 'can after the chain is properly through a new link has been restored,
ίο nicht neuerdings wieder Verwendung finden. Die bekannten Notglieder finden deshalb insbesondere beim landwirtschaftlichen Betriebe zum Verbinden zerrissener Kettenstränge, wie Zugketten, entweder keine oder nicht ohne weiteres Verwendung. Es ergibt sich dahingegen sehr oft die Notwendigkeit, sofort an Ort und Stelle einen zerrissenen Kettenstrang wiederherzustellen.ίο not recently used again. The known emergency links are therefore found in particular on farms for connecting broken chain strands, such as pull chains, either none or not without further use. On the other hand, there is very often the need to contact immediately Recover a broken chain strand on the spot.
Der Erfindungsgegenstand stellt nun ein Notglied dar, das im Bedarfsfalle ohne weiteres verwendet werden kann, wobei ein wirklicher Kettenschluß erzielt wird, und das Notglied kann späterhin, nachdem die Zugkette ordnungsmäßig wiederhergestellt worden ist, ohne weiteres wieder erneut verwendet werden.The subject matter of the invention now represents an emergency link which, if necessary, easily can be used, whereby a real chain connection is achieved, and the emergency link can later, after the pull chain has been properly restored, can be used again without further ado.
In der Zeichnung ist der Erfindungsgegenstand in einer Ausführungsform schaubildlich dargestellt.The subject matter of the invention is shown diagrammatically in one embodiment in the drawing shown.
Das Ketten-Notglied besteht aus dem Zugstab a, welcher mit kettengliedartigen Kopfstücken ausgestattet ist. Diese Kopfstücke bestehen aus den Querstegen b, den Auflagerstegen c und c1, dem Schutz- und Einführungssteg d und dem Schlußsteg e. The chain emergency link consists of the tension rod a, which is equipped with chain link-like head pieces. These head pieces consist of the transverse webs b, the support webs c and c 1 , the protective and insertion web d and the end web e.
Um das Notglied in eine zerrissene Kette einzusetzen, wird das Kettenglied zunächst über den Steg d geschoben, nach rückwärts geführt bis zum Steg c. In dieser Lage befindet sich das Kettenglied in quergerichteter 4^ Stellung, also um 900 verdreht gegenüber der dargestellten Lage. Hierauf wird das Kettenglied nach vorn geschwenkt, über den Stegarm c1 geschoben und in die gezeichnete Stellung zurückgedreht, so daß es sich nunmehr in richtiger Lage in dem Notglied befindet. Ein selbsttätiges Auslösen aus dieser kann nicht stattfinden, da das Notglied allseitig gehalten wird.In order to insert the emergency link into a broken chain, the chain link is first pushed over the web d and then guided backwards to the web c. In this position, the chain link is in transversely directed 4 ^ position, ie 90 0 rotated from the position shown. The chain link is then pivoted forward, pushed over the bridge arm c 1 and rotated back into the position shown so that it is now in the correct position in the emergency link. An automatic release from this cannot take place because the emergency link is held on all sides.
