The present invention is directed to a combustion-operated setting device for driving fastening elements such as nails, bolts and pins into a substrate, with a setting mechanism comprising a driving piston () which is supported to be displaceable in a guide, and with an electronic monitoring device for monitoring the status of the setting device. At least one sensor array () is arranged at the guide for generating a measurement data pattern which can be evaluated by the monitoring device.

Setting device

A setting tool includes a sleeve-shaped housing (), a piston guide () and an ignition unit () located in the housing (), with the ignition unit () having a cartridge chamber bottom () for enclosing a propellant () in cartridge chamber (), which is located between the piston guide () and the ignition unit () and a locking device () having a locking position () in which the ignition unit () is held in a pre-loaded position () against an energy accumulator () and in which the cartridge chamber () remains open, and having a release position () in which the ignition unit () is displaced to its ignition position () by the energy accumulator in which the cartridge chamber bottom () closes the cartridge chamber ().

Setting tool

A propellant magazine for a propellant-operated setting tool and including a pocket foil () having a plurality of recessed, spaced from each other, pockets () for receiving each a propellant (), a cover foil () unreleasably connected with the pocket foil () for closing the pockets (), and an electrically conducting strip () associated with each pocket () and having at least one contact point ().

A combustion-engined setting tool, including a housing (), an axially displaceable piston guide () and a firing pin guide () provided on a side of the piston guide () facing in the direction opposite the setting direction and axially displaceable relative to the housing (), damping element () supported against a stop () provided in the housing () and cooperating with the firing pin guide (), and a locking device () having a locking position () in which it prevents a press-on force, which is generated upon the setting tool () being pressed against a construction component, from acting on the damping element (), so that the damping element () remains inactive during a press-on process, and having a release position () in which the damping element () becomes active and is capable of absorbing recoil forces.

The present invention relates to a propellant charge magazine for setting tools and a setting tool for driving fasteners into a substrate. The propellant charge magazine of the invention comprises a housing () with an internal housing space for receiving a magazine strip with propellant charges (). At least one output opening () for inserting and extracting the magazine strip () is arranged on the housing. A first space () for receiving a rolled up magazine strip () is provided on the propellant charge magazine () and a second space () in contact with the first space () via an opening () and for accommodating part () of the magazine strip () that is re-introduced into the propellant charge magazine () is provided on the propellant charge magazine ().
