Description

Durch das Patent 836 489 ist ein Spannschloß für Grubenstempel geschützt, bei dem die konische Innenfläche eines gegebenenfalls als Gehäuse ausgebildeten Ringfeder-Außenringes auf die entgegengesetzt konischen Flächen einer geteilten Mutter wirkt. Die Segmente der geteilten Mutter stützen sich gegen einen Bund des Unterstempelrohres ab. Unterhalb des Bundes befindet sich eine Kurvenscheibe bzw. ein Exzenter, der auf zwei beiderseits am Schloßgehäuse befestigten Bolzen gelagert ist, wobei diese Kurvenscheiben oder Exzenter mittels eines Handhebels betätigt werden.A turnbuckle for pit punches is protected by patent 836 489, in which the conical inner surface of a possibly designed as a housing Ring spring outer ring on the oppositely conical surfaces of a split Mother works. The segments of the split nut are supported against a collar of the Lower punch tube. Below the collar there is a cam or an eccentric mounted on two bolts attached to both sides of the lock housing is, these cams or eccentrics operated by means of a hand lever will.

Die vorliegende Erfindung ist eine Weiterentwicklung dieses Schlosses, durch die dessen Bauweise vereinfacht und verbilligt wird. Die Bauhöhe verringert sich. Erfindungsgemäß sind die Bolzen selbst mit einer kurvenförmigen Ausnehmung versehen, so daß auf die bisherigen Exzenter bzw. Kurvenscheiben verzichtet werden, kann. Durch die erfindungsgemäße Maßnahme verringert sich auch der wirksame Hebelarm von Mitte Bolzen bis Oberkante Exzenter, so daß auch die zum Spannen und Lösen des Schlosses .erforderliche Kraft geringer wird. In der Zeichnung ist der Gegenstand der Erfindung in drei Abbildungen dargestellt.The present invention is a further development of this lock, through which its construction is simplified and cheaper. The overall height is reduced themselves. According to the invention, the bolts themselves have a curved recess provided so that the previous eccentrics or cam disks are dispensed with, can. The measure according to the invention also reduces the effective lever arm from the center of the bolt to the top edge of the eccentric so that the tensioning and loosening of the The force required by the lock becomes less. In the drawing is the object the invention shown in three figures.

Abb. r zeigt das Schloß im Querschnitt, Abb. 2 den Bolzen in vergrößertem Maßstab; Abb. 3 ist eine Stirnansicht zu Abb. a.Fig. R shows the lock in cross section, Fig. 2 the bolt in an enlarged view Scale; Fig. 3 is an end view of Fig. A.

Das entsprechend Abb. a des Hauptpatents ausgebildete Schloß besteht aus dem Gehäuse r, der geteilten Mutter 3 mit Federringen 4, die um das Oberstempelrohr 5 angeordnet sind und sich mittels des Bolzens 9 auf dem Unterstempelrohr 7 abstützen. Der Handbetätigungshebel trägt das Bezugszeichen ro.The lock designed according to Fig. A of the main patent exists from the housing r, the split nut 3 with spring washers 4 around the upper punch tube 5 are arranged and are supported on the lower punch tube 7 by means of the bolt 9. The manual operating lever has the reference symbol ro.

Entgegen der Ausführungsform nach dem Hauptpatent ist der Bolzen 9 als Exzenter ausgebildet (s. Abb. 3). Der Handhebel ro greift entweder direkt nach Art eines Vierkantschlüssels an den Bolzen 9 an, oder er ist mit Ansätzen verschweißt oder verschraubt, die mit den Bolzen 9 kraftschlüssig verbunden sind.Contrary to the embodiment according to the main patent, the bolt is 9 designed as an eccentric (see Fig. 3). The hand lever ro either engages directly Kind of a square wrench on the bolt 9, or it is welded with lugs or screwed, which are positively connected to the bolts 9.
