Abstract
A device for driving fastening elements into a substrate, having a combustion chamber in which a fuel can be burned for the purposes of transmitting energy to a fastening element, having a cartridge bearing which has a receiving chamber for a cartridge which contains the fuel, which receiving chamber is open in an opening direction toward the combustion chamber, having a closure which, in a closed position of the closure, closes the receiving chamber counter to the opening direction and bears against the cartridge bearing, and having a strip leadthrough, which defines a transport direction and opens into the receiving chamber, for a cartridge strip which bears the cartridge.
Claims20
An apparatus for driving fastening elements into a substrate, the apparatus having a combustion chamber in which a fuel can be burned to transmit energy to a fastening element;
- a cartridge holder having a receiving chamber for a fuel cartridge, the receiving chamber being open in an opening direction toward the combustion chamber;
- a closure which, in a closed position of the closure, bounds the receiving chamber in a direction opposite the opening direction;
- and
- a strip passage which defines a transport direction and which opens into the receiving chamber for a cartridge strip carrying the fuel cartridge, wherein the closure rests on the cartridge holder when the closure is in the closed position.
The apparatus according to claim 5, wherein the receiving chamber, viewed in the opening direction, has a partially circular circumference at a level of the cartridge holder chamfer and/or at a level of a bound to the receiving chamber formed by the closure.
A cartridge strip for a driving apparatus, the cartridge strip having a cartridge containing a fuel, and a carrier strip which carries the cartridge and defines a transport direction, wherein the carrier strip has a cartridge holder which defines an opening direction, and the cartridge is held in the cartridge holder such that the cartridge can open in the opening direction when the fuel is ignited, wherein the carrier strip has a tapered insertion surface on its front side which faces into the opening direction.
