Abstract
A handheld setting tool for driving a nail or bolt into a substrate, comprising: a drive, preferably a gas spring drive or an electrodynamic drive, which drives an actuator, which actuator is used to drive the nail or bolt into the substrate; characterised by: a decoupling device which at least partially decouples a first movement process of a first moving part or piston in the actuator, driven by the drive, from a second movement process of a second moving part or piston in the actuator so as to drive the nail or bolt into the substrate.
Claims25
Handheld setting tool for driving a nail or bolt into a substrate, comprising:
- a drive, driving an actuator (11) which serves to drive the nail or bolt into the substrate;
- characterised by:
- a decoupling device which at least partially decouples a first movement process of a first moving part or piston (111) in the actuator (11), driven by the drive, from a second movement process of a second moving part or piston (112) in the actuator (11) for driving the nail or bolt.
Handheld setting tool according to 1, wherein a compressible fluid, preferably air, is located between the first moving part or piston (111) and the second moving part or piston (112).
Handheld setting tool according to 10, wherein the drive is a gas spring drive, further comprising:
- at least one working gas reservoir (20) with a working gas, the further actuator (10) being a pneumatic actuator (10),
- the pneumatic actuator (10) comprising a third piston (101) with a piston rod (01), the third piston (101) being in fluid communication with the working gas reservoir (20), and forming a gas spring together with working gas reservoir (20),
- the pneumatic actuator (10) being movable between a stroke start position range in which the gas spring is under maximum tension, and a stroke end position range in which the gas spring is at least partially relaxed.
Handheld setting tool according to 12, wherein the pneumatic actuator (10) comprises a cylinder (12a, 12f), the cylinder (12a, 12f) being configured to incorporate a valve seat, the third piston (101, 10a) being configured to act as a shut-off element for this valve seat or to incorporate a corresponding shut-off element, so that the third piston (101, 10a) and the cylinder together form a valve which can be closed by pressing, by means of sufficient external force, the third piston (101, 10a) and thus the shut-off element against the valve seat formed by or attached to the cylinder (12a, 12f).
