An apparatus for driving a fastening element into a base material, comprising a power unit and a driving element which is provided driven by the power unit in a driving direction from a starting position into a setting position to drive a fastening element into the base material; a braking element with a contact surface which defines the setting position of the driving element and against which the driving element lies in the setting position; a pressing element which has an end surface which can be pressed in the driving direction onto the base material, wherein, in the driving direction, the end surface and the contact surface are at a distance from each other which defines a driving depth of the fastening element into the base material; and, an adjustment device with which the distance between the end surface and the contact surface can be adjusted.

Driving-in device

A hand-held setting tool for driving in fastening elements includes a pressure probe () displaceable between an extended position () in which the setting tool () cannot be actuated, and an operational position () in which the setting tool () can be actuated, and a blocking member () displaceable by a gravity force between its release position () in which it is located outside of a displacement path () of the pressure probe (), and a blocking position () in which it extends into the displacement path () of the pressure probe (), blocking displacement of a pressure probe () into its operational position.

Hand-held setting tool

A portable setting tool includes a housing ( ), a guide tube ( ) for guiding the fastening elements and connectable with the housing and having a side cut-out through which the fastening elements are fed into the guide tube ( ), and a feeler ( ) extendable into the guide tube ( ) at a location opposite the cut-out ( ) of the guide tube ( ) and having, at an end thereof extendable into the guide tube ( ), an end surface ( ) providing for displacement of the feeler ( ) in a direction transverse t a longitudinal axis ( ) of the guide tube ( ) upon being acted upon by a fastening element, and an adjusting rim ( ) adjoining the end surface ( ) and forming, with a longitudinal axis ( ) of the guide tube ( ), an acute angle (&agr; ) opening in a direction toward a mouth opening of the guide tube ( ) with the adjusting rim providing for displacement of the feeler ( ) in the transverse direction upon being acted upon by an object displaceable along the longitudinal axis ( ) of the guide tube ( ).

Portable setting tool for fastening elements

A piston for a setting tool and including a piston head ( ) having a hollow-chamber ( ) adjoining opening ( ) formed in the end surface of the piston head, and a stopper ( ) securable in the hollow chamber ( ) of the piston head ( ) with a solder seam for closing the opening ( ), a centering element ( ) provided on an outer circumference of the outer surface ( ) of the stopper ( ).

Piston for a setting tool

A setting tool including a stud guide ( ) located in the tool housing ( ), a hopper ( ) extending sidewise of the stud guide and having a guide channel extending parallel to a longitudinal extent of the hopper ( ) and having two guide regions ( ), a displaceable drawer ( ) arranged in the guide channel, a scroll spring ( ) provided in the drawer ( ) for retaining the drawer ( ) in its initial position and having its free end secured to the hopper ( ), a cover ( ) for closing the hopper and displaceable along the hopper ( ) between closed and open positions, the cover ( ) having an element ( ) for displacing the drawer ( ) from its initial position to its transporting position in which the drawer ( ) clears a section of the guide channel for insertion of the nail magazine, and elements ( ) for formlockingly connecting the drawer ( ) to the hopper ( ) in the transporting position of the drawer ( ).

Setting tool

The setting tool comprises a housing ( ), a firing device ( ) and an axially displaceable piston guide ( ). The simple assembly of the piston guide ( ) in the housing ( ) is made possible by a centering means acting between the piston guide ( ) and the housing. Guidance elements ( ), by means of the centering means, are eccentrically arranged on at least one of the piston guide ( ) and the firing device ( ) and extend essentially parallel to the setting direction. The guidance elements ( ) are coaxially disposable on at least one of the piston guide ( ) and the firing device ( ) relative to corresponding receiving openings ( ) on the piston guide ( ) and the firing device ( ).

A setting tool comprised of a housing ( ), a handle ( ), an axially displaceable firing device ( ), an axially displaceable piston guide ( ) with a cartridge chamber ( ) and a guide channel for receiving and guiding a strip-shaped cartridge magazine ( ) that opens into a discharge opening ( ) in the housing ( ). A length (L) extends between a setting-side inside wall of the discharge opening ( ) and a setting-side front face ( ) of the firing device ( ) in the starting position so that a used cartridge magazine ( ) 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 ( ) can be displaced.

A power force adjustment for a setting tool has a housing ( ), a mechanism for adjustment of power force using a adjustment wheel ( ) rotatable around an axis ( ) and a lever ( ) pivotally movable around a pivot axis, the lever preventing any movement of the adjustment wheel ( ) when in the locked position and when in the release position allows free rotation of the adjustment wheel ( ).
