Patent number: 6491199Abstract: A setting tool comprised of a housing (1), a handle (2), an axially displaceable firing device (10), an axially displaceable piston guide (11) with a cartridge chamber (13) and a guide channel for receiving and guiding a strip-shaped cartridge magazine (15) that opens into a discharge opening (4) in the housing (1). A length (L) extends between a setting-side inside wall of the discharge opening (4) and a setting-side front face (18) of the firing device (10) in the starting position so that a used cartridge magazine (15) can assume an inclined position relative to the longitudinal axis of the guide channel, after the last cartridge is fired. The length (L) is initially between 15 mm to 20 mm and then a length that corresponds to the greatest path by which the firing device (10) can be displaced.Type: GrantFiled: February 13, 2002Date of Patent: December 10, 2002Assignee: Hilti AktiengesellschaftInventors: Norbert Wohlwend, Dionys Schalbetter, Johann Büchel
