 EMI1.1 
 



   Die Erfindung betrifft einen   Drucklufthammer   mit einem aufgeschraubten Griff, der an der Verschraubung aufgeschnitten und mittels Schrauben, die durch Lappen an der Schnittstelle hindurchtreten, festgeklemmt ist. Von den bekannten Griffbefestigungen dieser Art unterscheidet sich der Erfindungsgegenstand durch eine Sicherung, die ein Zurückdrehen des Griffes auch bei Lockerwerden der Verschraubung verhindert. Gerade bei   Drucklufthämmern ist   eine derartige Sicherung von   besonderem   Wert, weil die dauernden Erschütterungen ein Lockerwerden der Schrauben begünstigen.

   Es sind daher auch bereits derartige Sicherungen zur Anwendung gekommen, jedoch nicht bei   der oben näher ge-     koun/. etelbneten   Art von Griffen,   durch   die gerade eine besonders einfache Sicherung er-   möglicht wird.   



   Auf   der Zeichnung   ist die Erfindung dargestellt und zwar zeigt : Fig. 1 einen Längs-

Er endet in einen Rohransatz 6', der aufgeschnitten und an der Schnittstelle mit Lappen 7 versehen ist, durch welche die zum Festpressen dienenden Schrauben 10 hindurchgezogen werden. Gemäss der Ereindung ist nun am Umfange des

 und angezogen, so ist der Griff gegen jede Drehung auch nach Lockerwerden der Verschraubung gesichert.

 EMI1.1
 



   The invention relates to a pneumatic hammer with a screwed-on handle which is cut open at the screw connection and clamped by means of screws which pass through tabs at the interface. The subject of the invention differs from the known handle fastenings of this type in that it has a safety device that prevents the handle from turning back even if the screw connection is loosened. This type of securing is of particular value, especially with pneumatic hammers, because the constant vibrations encourage the screws to loosen.

   Fuses of this type have therefore already been used, but not in the case of the koun /. A flat type of handle which enables particularly simple securing.



   The invention is shown in the drawing, namely: Fig. 1 shows a longitudinal

 section, Fig. 3 even cross-section along line a-a of Fig. 2. The design of the handle 4 of the tool corresponds to that which is common in pneumatic tools. It ends in a pipe extension 6 ', which is cut open and provided at the interface with tabs 7 through which the screws 10 used for pressing are pulled. According to the discovery, the extent of
