Description

Die vorliegende Erfindung betrifft einen Treibmittelbehälter für brennkraftbetriebene Setzgeräte zum Eintreiben von Befestigungselementen, wie Nägeln, Bolzen, Stiften in einen Untergrund, der im Oberbegriff von Patentanspruch 1 genannten Art sowie ein brennkraftbetriebenes Setzgerät der im Oberbegriff von Patentanspruch 5 genannten Art. Derartige Treibmittelbehälter können mit Pulverbrennstoffen in Pillen- oder Kartuschenform, oder aber auch mit flüssigen oder gasförmigen Brennstoffen als Treibmittel befüllt sein. Diese Treibmittel dienen im Setzgerät zum Antrieb eines Setzwerks.The present invention relates to a propellant container for combustion-powered setting tools for driving fasteners, such as nails, bolts, pins in a substrate referred to in the preamble of claim 1 and a type of combustion-driven setting tool referred to in the preamble of claim 5. Art Such propellant containers can with powder fuels in pills or cartridges, or else filled with liquid or gaseous fuels as blowing agent. These propellants are used in the setting tool to drive a Setzwerks.

Ein derartiger Treibmittelbehälter und ein derartiges Setzgerät gehen beispielsweise aus der US 4 443 280 hervor.Such a propellant container and such setting tool go for example from the US 4,443,280 out.

Aus der US 4,204,473 ist ein brennkraftbetriebenes Setzgerät und ein Kartuschenstreifen mit einer Vielzahl von Pulverladungen bekannt, wobei der Kartuschenstreifen in einer Magazinbox als Treibmittelbehälter angeordnet ist. Der Kartuschen- oder Magazinstreifen ist in dieser Magazinbox in Lagen angeordnet.From the US 4,204,473 a combustion-powered setting device and a cartridge strip with a plurality of powder charges is known, wherein the cartridge strip is arranged in a magazine box as a propellant container. The cartridge or magazine strip is arranged in layers in this magazine box.

Gasförmige und/oder flüssige Brennstoffe als Treibmittel werden hingegen in, als Druckbehälter ausgeführten Treibmittelbehältern bereitgestellt. Ein derartiger, als Treibmittelbehälter geeigneter Druckbehälter ist z. B. aus der DE 197 46 018 C2 bekannt.On the other hand, gaseous and / or liquid fuels as propellants are provided in propellant containers designed as pressure vessels. Such, suitable as a propellant container pressure vessel is z. B. from the DE 197 46 018 C2 known.

Bei brennstoffbetriebenen Setzgeräten geht die Entwicklung dahin, dass immer mehr stromverbrauchende mechatronische Funktionen in den Setzgeräten vorgesehen sind.
So ist aus der US 4,483,280 ein Setzgerät bekannt, bei der ein elektrisch betriebener Lüfter zum Spülen der Brennkammer vorgesehen ist. Die notwendige elektrische Energie wird dabei über in einem Batteriefach angeordnete Batterien bereitgestellt. Der Treibmittelbehälter ist als Druckbehälter in einem separaten Gehäusefach im Setzgerät angeordnet.With fuel-operated setting tools, the trend is that more and more power-consuming mechatronic functions are provided in the setting devices.
So is out of the US 4,483,280 a setting device is known in which an electrically operated fan is provided for purging the combustion chamber. The necessary electrical energy is provided via batteries arranged in a battery compartment. The propellant container is arranged as a pressure vessel in a separate housing compartment in the setting tool.

Von Nachteil hierbei ist zum einen, dass im Gehäuse zwei Fächer vorgesehen werden müssen, was zu höheren Produktionskosten führt. Zum anderen muss ein Anwender den Druckbehälter und die Batterien jeweils separat wechseln, wenn diese leer sind.The disadvantage here is, on the one hand, that two compartments must be provided in the housing, which leads to higher production costs. On the other hand, a user must change the pressure vessel and the batteries separately when they are empty.

Die Aufgabe der vorliegenden Erfindung liegt daher darin, einen Treibmittelbehälter und ein Setzgerät der vorgenannten Art zu entwickeln, die die genannten Nachteile vermeiden und dem Anwender ein einfaches Handling eines Setzgerätes und eines Treibmittelbehälters ermöglichen.The object of the present invention is therefore to develop a propellant container and a setting tool of the aforementioned type, which avoid the disadvantages mentioned and allow the user easy handling of a setting device and a propellant container.

Demnach wird an dem Treibmittelbehälter eine ortsunabhängige Stromquelle, wie eine Batterie oder ein Akkumulator, angeordnet. Durch diese Massnahme muss der Anwender eines Setzgerätes nur noch den Treibmittelbehälter auswechseln, wenn dieser leer ist, wodurch Zeit eingespart wird. Ferner wird Bauraum am Setzgerät eingespart, da eine separate Aufnahme für die Stromquelle nicht mehr vorgesehen werden muss.Accordingly, a location-independent power source, such as a battery or an accumulator, is arranged on the propellant container. By this measure, the user of a setting tool only has to replace the propellant container when it is empty, which saves time. Furthermore, space is saved on the setting device, since a separate recording for the power source no longer needs to be provided.

In einer vorteilhaften Ausgestaltung der Erfindung ist die Stromquelle entnehmbar/auswechselbar in einer Aufnahme am Treibmittelbehälter angeordnet. Durch die Anordnung in einer Aufnahme kann die Batterie dem Treibmittelbehälter wieder entnommen werden, wodurch eine getrennte Entsorgung, oder sogar eine Wiederverwendung der Stromquelle (z. B. in einem weiteren Treibmittelbehälter) ermöglicht wird.In an advantageous embodiment of the invention, the power source is removable / interchangeable arranged in a receptacle on the propellant container. By locating in a receptacle, the battery can be removed from the propellant container, allowing separate disposal, or even reuse of the power source (eg, in another propellant container).

Derartige Vorteile ergeben sich auch, wenn die Stromquelle an dem Treibmittelbehälter über eine Klipsverbindung entnehmbar/auswechselbar gehalten ist.Such advantages also arise when the power source is held on the propellant container via a clip connection removable / interchangeable.

In einer preisgünstig herzustellenden Variante ist die Stromquelle an dem Treibmittelbehälter über eine Klebeverbindung gehalten.In a variant to be produced inexpensively, the power source is held on the propellant container via an adhesive connection.

In einer vorteilhaften Weiterbildung der Erfindung ist der Energieinhalt der Stromquelle an den Treibmittelinhalt des Treibmittelbehälters angepasst. So deckt z. B. die in der Stromquelle gespeicherte Energie, bei einem Treibmittelinhalt des Treibmittelbehälters für 100 Setzvorgänge, die Stromversorgung der elektrischen Verbraucher des Setzgerätes für diese 100 Setzvorgänge.In an advantageous embodiment of the invention, the energy content of the power source is adapted to the propellant content of the propellant container. So z. As the energy stored in the power source, with a propellant content of the propellant container for 100 setting operations, the power supply of the electrical consumers of the setting device for these 100 setting operations.

Bei einem erfindungsgemässen Setzgerät ist es günstig, wenn an bzw. im Bereich der Aufnahme für den Treibmittelbehälter Kontaktelemente zur Kontaktierung der am Treibmittelbehälter angeordneten Stromquelle angeordnet sind. Durch diese Massnahme muss der Anwender eines Setzgerätes nur noch den Treibmittelbehälter auswechseln, wenn dieser leer ist, wodurch Zeit eingespart wird. Ferner wird Bauraum am Setzgerät eingespart, da eine separate Aufnahme für die Stromquelle nicht mehr vorgesehen werden muss.In a setting tool according to the invention, it is favorable if contact elements for contacting the power source arranged on the propellant container are arranged on or in the region of the receptacle for the propellant container. By this measure, the user of a setting tool only has to replace the propellant container when it is empty, which saves time. Furthermore, space is saved on the setting device, since a separate recording for the power source no longer needs to be provided.
