  • the Abblaskanal can be connected to an outside space.
  • the blow-off channel may also be a dead space volume not connected to an exterior space.
  • a driving energy is understood to mean the kinetic energy of a given fastening element for a given propellant charge. Upon specification of these boundary conditions, it is possible by the actuator to adjust the resulting driving energy of the fastener adjustable.
  • a piston member according to the invention is any means that is acted upon by the ignition of the charge with kinetic energy, wherein the kinetic energy is ultimately transmitted to the fastener.
  • the piston member is designed as a particular cylindrical piston.
  • recesses or other structures may be provided which further promote turbulence and uniform expansion of the fuel gases.
  • a central axis in the sense of the invention is an axis at least parallel to the movement of the fastening element, which runs through a center of the combustion chamber.
  • the central axis extends through both the center of the combustion chamber and through a center of the fastener.
  • any retractable anchoring such as nail, bolt or screw understood.

  • the slide is also useful a guide of the piston member in a first portion of the piston movement.
  • the actuator has a pivotable about the central axis control panel.
  • the control panel may be any suitable means for manual adjustment, such as a rotatable sleeve as a particularly preferred variant, a pivotable knob or the like.
  • the operating part is designed as an annular sleeve, wherein the sleeve surrounds the central axis.
  • the sleeve can be rotated in several different positions, wherein at least two different positions are assigned to two different drive energies.
  • the sleeve can be held by means of a locking member in at least one defined position.
  • Such defined positions may be a maintenance position or a defined position for changing the driving energy.
  • An inventive control panel and in particular a sleeve described above can be arranged to optimize the ergonomics of the device in a front area in front of a handle of the device.
  • an advantageous analogy to known controls of hand-held Drilling machines and / or cordless screwdrivers result.
  • the controls of such devices are used according to other purposes, such as a torque adjustment or a change from screwing to hammer operation in a percussion drill.
  • a pivoting of the operating part about the central axis means a substantially perpendicular to the axis oriented deflection of the control panel from a previous position.
  • a movement line or trajectory of the operating part has a radius of curvature, which is preferably not smaller than a distance of the operating part from the central axis.
  • the pivoting is a rotation about the central axis.
  • control panel and the slider are rotatably connected, so that a rotation of the control panel at the same time causes a rotation and adjustment of the slider for regulating the driving energy.
  • a piston guide arranged in front of the combustion chamber is received rotatably relative to the housing about the central axis.
  • the piston guide and the slide are particularly non-rotatably coupled to each other and axially movable relative to one another.
  • the piston guide fulfills an additional function as a mechanical link between the slider and a control panel.
  • the slider has a collar which runs around the central axis and overlaps into a recess of a combustion chamber housing, wherein at least part of the blow-off channel is formed as an axially extending recess between the collar and the combustion chamber housing.
  • a drive-in device comprises a hand-guided housing 1, in which a piston member in the form of a piston 2 is accommodated.
  • a surface 2a of the piston 2 defines a combustion chamber 3 in which the combustion gases of a pyrotechnic charge expand to accelerate the piston 2.
  • the fastening element may in particular be accommodated in a module or magazine (not shown) that is interchangeable in a front holding region 1a of the tacker device 1.
  • the charge is presently received in a cartridge 4a made of sheet metal.
  • the cartridge 4a has an impact fuse and is inserted into a cartridge bearing 4 before ignition via a corresponding loading mechanism, in the present case by means of a magazine strip.
  • the cartridge and the cartridge bearing 4 are rotationally symmetrical about one Central axis A formed.
  • the central axis A is in the present examples at the same time a central axis of the combustion chamber 3 and the piston member. 2
  • the combustion chamber 3 is formed in a first section as a hollow cylindrical, substantially sleeve-shaped body 6.
  • This body 6 is at the same time as a rotatable about the central axis A and thereby in its position in the direction of the central axis A variable slide for adjustable release of one or more Abblaskanäle 7 formed with, for example, stepped cross-section.
  • the exhaust duct 7 comprises a plurality of recesses 7a in a combustion chamber housing 8 distributed over the circumference.
  • the recesses 7a extend axially in the direction parallel to the central axis A and open into a section of the exhaust duct 7 with a larger volume running between the combustion chamber housing 8 and a piston guide 5.
  • a cylindrical recess with a multi-start internal thread 8a In the combustion chamber housing 8 is located in the region of the combustion chamber, a cylindrical recess with a multi-start internal thread 8a.
  • the slider 6 is screwed with a corresponding external thread 6a in the opening of the combustion chamber housing 8. A rotation of the slider 6 about the central axis A thus causes a positively controlled axial displacement of the slider. 6
  • the slide 6 is provided with a collar 6b which extends to the rear or in the direction of a bottom of the combustion chamber 3 and engages in the recess of the combustion-chamber housing 8 in an axially overlapping manner.
  • a variable passage 9 is thus released from the combustion chamber 3 into the recesses or blow-off channels 7a (see FIG Fig. 5 ).
  • the passage 9 is closed when completely displaced to the rear slider 6 (see Fig. 6 ). If an opened passage 9 is set, then this is a part of the blow-off duct 7a, 7.
  • the passage is arranged in the axial direction immediately in front of the bottom of the combustion chamber 3, so that combustion gases can escape into the blow-off duct immediately at the beginning of the piston movement. hereby Depending on the setting of the slide 6, a particularly large area of energy reduction can be achieved.
  • a front end of the piston guide 5 is rotatably coupled to a control panel 10. so that the piston guide 5 at the same time forms a mechanical connection between the operating part 10 and the slide 6.
  • the operating part 10 is designed as a sleeve rotatable in the combustion chamber housing, which sleeve is arranged substantially concentrically around the central axis A in a front region of the housing 1 of the tacking device.

  • This adjustment and the drive operation work as follows:
  • the piston member After a Eintreibvorgang the piston member is in a partially undefined, but largely shifted forward position.
  • the combustion chamber housing 8 is located in a maximally pushed back into the tacker in position.
  • front and rear are always selected with reference to the driving direction.
  • the desired driving energy is set as the energy level marked on the operating part by rotating the sleeve 10. This leads via the positive control described above to a selected axial positioning of the slide 6 relative to the combustion chamber housing 8. As a result, the blow-off channel is released or closed defined via the passage 9 (maximum driving energy).
  • a corresponding part of the propellant gases or exhaust gases is discharged to the outside via the described channels 7a, 7.
  • a closed dead space volume may be provided, for example, the Abblaskanäle 7a serve only as an optional room extension of the combustion chamber and are not connected further to the outside.
