Eine Vorrichtung zum Eintreiben von Nägel ist z.B. aus der EP-A-321 440 bekannt. Hierin ist eine Nagelvorrichtung gezeigt, bei der ein Schlagkörper über ein Gelenk mit einer Magazin-,Nagelführungs-, Treibführungseinheit verbunden ist. In einem Hammerkopf des Schlagkörpers ist ein die Nägel aus der Magazin-,Nagelführungs-, Treibführungseinheit bei Aufbringen einer Druckkraft auf den Schlagkörper austragender Treiber schwenkbar gelagert. Die Magazin-,Nagelführungs-, Treibführungseinheit weist ein zylindrisches Trommelmagazin auf, aus welchem die Nägel mit Hilfe einer Vorschubklaue in Richtung des Treibers bewegt werden, wobei der Vorschub entweder über ein Getriebe- bzw. Hebelsystem oder ein Federhebelsystem erfolgt. Zum Auseinanderdrücken des Schlagkörpers und der Einheit in einer Ruhestellung ist eine zwischen diesen beiden Teilen unter Vorspannung eingebrachte Feder vorgesehen. Für das Eintreiben der Nägel sind entsprechende Kräfte erforderlich, die sich negativ auf alle Lager der Nagelvorrichtung auswirken. Demzufolge kommt es rasch zu Abnützungserscheinungen, die ein großes Spiel in den Lagern sowie eine inexakte Führung und einen inexakten Vorschub der Nägel mit sich bringt; häufige Fehlfunktionen der Vorrichtungen sind die Folge. A device for driving in nails is e.g. from the EP-A-321 440 is known. A nailing device is shown here at which strikes a body over a joint with a magazine, nail guide, Drive management unit is connected. In a hammer head of the Impact body is a the nails from the magazine, nail guide, Drive guide unit when a pressure force is applied to the impact body discharge driver pivoted. The magazine, nail guide, Drive guide unit has a cylindrical drum magazine on, from which the nails with the help of a feed claw in the direction of the driver can be moved, the feed either via a gear or lever system or a spring lever system. To push apart the impact body and the unit in one Rest position is one between these two parts under tension introduced spring provided. Appropriate for driving in the nails Forces required that adversely affect all bearings of the Impact nailing device. As a result, signs of wear appear quickly, which is a big game in the camps as well as an inexact one Guidance and an inexact feed of the nails; frequent Malfunctions of the devices are the result.

Für die Verwendung von Nagelgeräten, deren Betrieb durch Pressluft, Gas, elektrische Energie oder durch Hand erfolgt, werden magazinierte Nägel verwendet. Ein solches Nagelmagazin enthält dabei bis zu 140 parallel ausgerichtete Nägel, die durch einen Draht der an den Nagelschäften z.B. angeschweißt ist, miteinander verbunden sind. Durch die Verformbarkeit des Drahtes lässt sich das so erhaltene Nagelband zu einem Coil aufwickeln, in welcher Form es in ein entsprechendes Nagelgerät eingesetzt wird. Bei den bisherigen Ausführungsformen bestanden die Verbindungsdrähte aus weichen unlegierten Metallen, die ein einwandfreies Coillieren und Verschweißen der Draht-Nagelverbindung gestatten. Eine Verarbeitung dieser Ausführungsform mit einem Nagelgerät ist schwierig oder überhaupt nicht möglich, da es durch die Schlagbewegung zu einer Stauchung der Nagelabstände kommt. Weiters legen sich die Nägel zum Magazinmittelpunkt um. Es kommt in der Praxis immer wieder zu Fehlfunktionen der Nagelgeräte, da, wie gesagt, die Nägel sich im Nagelgerät verkeilen, wenn es zu einer Verdrehung kommt, und weil sie vom Hammerelement des Nagelgerätes gestaucht und umgelegt werden. Insbesondere tritt diese Fehlfunktion auf, wenn ein Großteil des Nagelbandes bereits verbraucht ist und der Rest des Nagelband-Coils frei im Magazin liegt.For the use of nail tools, their operation by compressed air, Gas, electrical energy or by hand are stored in magazines Used nails. Such a nail magazine contains up to 140 parallel aligned nails through a wire attached to the nail shafts e.g. is welded together. Through the The nail tape obtained in this way allows the wire to be deformed a coil, in what form it in an appropriate nailing device is used. Passed in previous embodiments the connecting wires made of soft unalloyed metals, the perfect coiling and welding of the wire-nail connection allow. Processing of this embodiment with a Nailing device is difficult or not possible at all as it is caused by the Stroke movement leads to a compression of the nail spacing. Furthermore, lay the nails around the center of the magazine. It comes in practice Again and again malfunctions of the nail tools, because, as I said, the Nails get wedged in the nailing device if it twists, and because it is compressed and folded by the hammer element of the nailing device become. In particular, this malfunction occurs when much of it of the nail ribbon is already used up and the rest of the nail ribbon coil lies freely in the magazine.

Aufgabe der vorliegenden Erfindung ist es, die oben genannten Nachteile zu beseitigen.The object of the present invention is to overcome the disadvantages mentioned above to eliminate.

Die Aufgabe wird dadurch gelöst, dass die Welle mit dem Hammerkopf fest verbunden oder einstückig ist und durch eine Ausnehmung im Kulissenhebel ragt, wobei als federndes Element der Bereich zwischen der Begrenzung dieser Ausnehmung und der Welle bzw. einer die Welle drehfest umgebenden Buchse mit Gummi ausgefüllt ist, gegen dessen elastische Kraft der Kulissenhebel beim Nagelvorgang verschwenkt wird. Dieser federnde Gummi dämpft die durch die Schlagbewegung auftretenden Kräfte auf das Kulissenlager, so dass es zu einem viel geringeren Verschleiß dieses Lagers kommt, als es bei Vorrichtungen des Standes der Technik der Fall ist. Gleichzeitig erzeugt der Gummi eine Rückstellkraft für den bei der Schlagbewegung zurückgezogenen Vorschubkörper und übernimmt damit eine sichere Positionierung des nächsten Nagels im Schlagkanal.The task is solved in that the shaft with the hammer head is firmly connected or in one piece and through a recess in the link lever protrudes, the area between the Limitation of this recess and the shaft or the shaft rotatably surrounding socket is filled with rubber against its elastic Force the link lever is pivoted during the nailing process. This resilient rubber dampens the impact of the impact movement Forces on the link bearing, making it a much smaller one Wear of this bearing comes as it does with devices of the state technology is the case. At the same time, the rubber creates a restoring force for the withdrawn during the stroke movement Feed body and thus takes over a safe Position the next nail in the blow channel.

Vorzugsweise ist die Welle im Querschnitt dreieckig und von einer sternförmigen Buchse umgehen. Die sternförmige Buchse ist drehfest gegenüber der dreieckigen Welle und ergibt auch eine langlebige drehfeste Verbindung zwischen dem Gummi und ihrer äußeren Oberfläche.The shaft is preferably triangular in cross section and bypass a star-shaped socket. The star-shaped Socket is non-rotatable in relation to the triangular shaft and also results in a durable, non-rotatable connection between the rubber and its outer surface.

Gemäß einer besonderen Ausführung der Erfindung ist die von der Welle durchragte Ausnehmung im Kulissenhebel von einem ringförmigen Ansatz umgeben, der vorzugsweise mit dem Kulissenhebel einstückig ist, und der Gummi reicht auch in den ringförmigen Ansatz. Der ringförmige Ansatz vergrößert die Verbindungsfläche zwischen Kulissenhebel und Gummi so daß diese Verbindung haltbarer ist.According to a particular embodiment of the invention recess penetrated by the shaft in the link lever of surrounded an annular approach, preferably with the link lever is in one piece, and the rubber is enough even in the annular approach. The ring-shaped approach increases the connection area between the link lever and rubber so that this connection is more durable.

Der Kulissenhebel weist an seinem dem Vorschubkörper abgewandten Ende eine Auflauffläche auf, die beim Betätigen der Nagelvorrichtung unter Verschwenken des Kulissenhebels an einem Auflaufbolzen im Winkelanschlag gleitet. Die Verschiebung des Vorschubkörpers ist damit beim Betätigen der Nagelvorrichtung gesichert, wobei die Übertragung der Bewegung als praktisch störungsfrei anzusehen ist.The link lever has on its facing away from the feed body End a ramp surface that when pressed the nailing device by pivoting the link lever slides on a stop pin in the angle stop. The displacement of the feed body is thus when actuated the nailing device secured, the transfer the movement can be regarded as practically undisturbed is.

Vorzugsweise ist der Auflaufbolzen der Lagerbolzen für den Schlagbolzen, so daß im Winkelanschlag nur ein Bolzen vorgesehen werden muß.The bearing bolt is preferably the bearing bolt for the firing pin, so that only one pin in the angle stop must be provided.

Nach einer Ausführungsform der Erfindung ist die Vorschubklaue bzw. sind die Vorschubklauen im Vorschubkörper federgelagert. Die Vorschubklauen können somit beim Zurückziehen des Vorschubkörpers den von einer Rückhaltefeder gehaltenen Nägeln ausweichen. According to one embodiment of the invention, the feed claw is or are the feed claws in the feed body spring loaded. The feed claws can thus be retracted of the feed body by a retaining spring dodge held nails.

Nach einem anderen bevorzugten Ausführungsbeispiel sind an dem Vorschubkörper mindesens zwei, vorzugsweise drei, feste Vorschubklauen, vorzugsweise aus Stahl angeordnet. Hier muß zwar die gesamte Ausweichbewegung der Nägel beim Zurückschieben des Vorschubkörpers durch die den Vorschubklauen gegenüber liegende Rückhaltefeder bewerkstelligt werden. Diese Ausführung ist jedoch wesentlich robuster und auch kostengünstiger.According to another preferred embodiment on the feed body at least two, preferably three, fixed feed claws, preferably made of steel. Here, the entire evasive movement of the nails must Push the feed body back through the feed claws opposite retaining spring accomplished become. However, this version is much more robust and also cheaper.

Zur Nagelkopfführung ist im Hammerkopf und in jenem Teil des Hebelteils, der den Hammerkopf mit dem Magazin verbindet, eine Nut vorgesehen. In dem gegenüberliegenden Magazinunterteil ist eine, die gegurteten Nägel führende und gegen Zurückziehen sichernde Rückhaltefeder angeordnet. Dadurch ergibt sich eine sichere Führung, insbesonder auch der am Ende eines Nagelbandes angeordneten Nägel sowie eine Sicherung, daß die Nägel beim Zurückziehen des Vorschubkörpers nicht mitzurückgezogen werden.For the nail head guide is in the hammer head and in that part the lever part that connects the hammer head with the magazine, a groove is provided. In the opposite Magazine base is one that guides the taped nails and retention spring to prevent retraction. This results in safe guidance, in particular also the nails arranged at the end of a nail ribbon and a backup that the nails when pulling back the Feed body are not pulled back.

Vorzugsweise ist die Rückhaltefeder aus Metall und enthält eine oder mehrere Rückhalteklauen, die aus dem Federkörper gestanzt und herausgebogen sind. Diese Rückhalteklauen liegen auf der Höhe eines der Verbindungsdrähte bzw. des Verbindungsdrahtes der gegurteten Nägel. Die Metallfeder ist robust und die Klaue läßt sich durch Ausstanzen und Aufbiegen relativ einfach herstellen. Da sie auf der Höhe des Verbindungsdrahtes der Nägel angeordnet ist, wird das Verklemmen des Nagelschaftes in der Klaue verhindert.The retaining spring is preferably made of metal and contains one or more retention claws coming from the spring body are punched and bent out. These retention claws are at the level of one of the connecting wires or the connecting wire of the strapped nails. The metal spring is robust and the claw can be punched out and bending open relatively easily. Since she arranged at the level of the connecting wire of the nails jamming of the nail shaft in the claw prevented.

Gemäß einer besonderen Ausführungsform ist in der Achse des Nagelmagazins eine Wickelhülse vorgesehen ist, deren Außendurchmesser dem Innendurchmesser des Coils entspricht und deren Zylinderfläche an den Nagelschäften unter Freistellung der Nägelköpfe bzw. an den Drähten der innersten Coillage anliegt. Damit kommt es selbst bei der Verarbeitung der letzten Nägel eines Nagelbandes nicht zu Fehlfunktionen der Nagelvorrichtung.According to a special embodiment is in the axis of the nail magazine a winding sleeve is provided, the Outer diameter corresponds to the inner diameter of the coil and their cylinder surface under the nail shafts Exemption of the nail heads or on the wires of the innermost coilage is present. So even with the Processing the last nails of a nail band too Malfunction of the nailing device.

Die Freistellung der Nagelköpfe wird vorzugsweise dadurch gewährleistet, daß die Wickelhülse ein Zylinder ist und in einem Abstand vom Magazinboden angeordnet ist, oder daß die Wickelhülse eine ringförmige Nut zur Aufnahme der Nägelköpfe aufweist.The exemption of the nail heads is preferably thereby ensures that the winding tube is a cylinder and is arranged at a distance from the magazine bottom, or that the winding tube has an annular groove for receiving the Has nail heads.

Fig. 1 zeigt den Hebelteil 1 mit dem Nagelmagazin 2 und dem Hammerkopf 3. Im Hammerkopf 3 ist eine Öffnung 4 vorgesehen, in der der Vorschubkörper 5 verschiebbar eingesetzt ist. Weiters ist der Hammerkopf 3 fest mit einer im Querschnitt dreieckigen Welle 6 verbunden, die drehfest in eine sternförmige Buchse 7 eingreift und durch eine Ausnehmung im Kulissenhebel 8 ragt. Die Ausnehmung ist von einem ringförmigen Ansatz 9 begrenzt und der Bereich zwischen der Begrenzung der Ausnehmung und der sternförmigen Buchse 7 sowie zwischen dem ringförmigen Ansatz 9 und der Buchse 7 ist mit dem Gummi 10 ausgefüllt. Der Kulissenhebel 8 ist an seinem einen Ende gabelförmig ausgebildet und umgreift mit dieser Gabel einen Bolzen 11, der mit dem Vorschubkörper 5 fest verbunden ist, so daß bei Verdrehen des Kulissenhebels 8 die Gabel des Kulissenhebels 8 über den Bolzen 11 den Vorschubkörper 5 verschiebt. Auf dem dem Vorschubkörper 5 abgewandten Ende des Kulissenhebels 8 ist eine Auflauffläche 12 vorgesehen, die bei Betätigung der Nagelvorrichtung am Auflaufbolzen 13, der im Winkelanschlag 20 gelagert ist, entlanggieitet und dadurch den Kulissenhebel 8 verschwenkt. Gleichzeitig ist am Auflagerbolzen 13 der Schlagbolzen 14 gelagert. Die Fig. 1 zeigt die Nagelvorrichtung im entspannten Zustand. Sobald die Nagelvorrichtung betätigt wird, wird der Kulissenhebel 8 gegen die elastische Kraft des Gummis 10 verdreht. Ist der Nagelvorgang beendet, so wird der Schlagbolzen 14 im Schlagkanal 15 hochgezogen und die unter Spannung befindliche Gummimasse 10 stellt den Kulissenhebel 8 in die in Fig. 1 gezeigte Position zurück. Dabei gleitet die Auflauffläche 12 des Kulissenhebels 8 am Auflaufbolzen 13 zurück und der Vorschubkörper 5 wird in seine vordere Position nahe dem Schlagkanal 15 im Hammerkopf 3 gebracht, um den nächsten Nagel im Schlagkanal 15 zu positionieren.Fig. 1 shows the lever part 1 with the nail magazine 2 and the hammer head 3. An opening 4 is provided in the hammer head 3, in which the feed body 5 is slidably inserted is. Furthermore, the hammer head 3 is fixed with a Cross-section triangular shaft 6 connected to the rotation engages in a star-shaped socket 7 and through a Recess in the link lever 8 protrudes. The recess is bounded by an annular extension 9 and the area between the boundary of the recess and the star-shaped Socket 7 and between the annular extension 9 and the bushing 7 is filled with the rubber 10. The link lever 8 is fork-shaped at one end and engages with this fork a bolt 11 which is firmly connected to the feed body 5, so that at Rotate the link lever 8 the fork of the link lever 8 moves the feed body 5 over the bolt 11. On the end facing away from the feed body 5 a sliding surface 12 of the link lever 8 is provided, when the nailing device is actuated on the thrust pin 13, which is mounted in the angle stop 20, alonggieitet and thereby pivoted the link lever 8. At the same time, the firing pin 14 is on the support pin 13 stored. Fig. 1 shows the nail device in the relaxed Status. As soon as the nailing device is actuated is, the link lever 8 against the elastic force of the rubber 10 twisted. If the nailing process is finished, so the firing pin 14 is pulled up in the firing channel 15 and the rubber mass 10 under tension the link lever 8 in the position shown in Fig. 1 back. The run-up surface 12 of the link lever slides 8 back on the thrust pin 13 and the feed body 5 will be in its forward position near the blow channel 15 brought in the hammer head 3 to the next nail in Position blow channel 15.

In der Fig. 2 ist der Kulissenhebel 8 von der Seite dargestellt. Man erkennt den ringförmigen Ansatz 9, der vorzugsweise mit dem Kulissenhebel 8 einstückig ist. Innerhalb des ringförmigen Ansatzes 9 befindet sich die sternförmige Buchse 7, die eine dreieckige Ausnehmung hat, um die Welle 6, die fest mit dem Hammerkopf 3 verbunden ist, aufzunehmen. Zwischen der sternförmigen Buchse 7 und dem ringförmigen Ansatz 9 sowie der dahinterliegenden Ausnehmung im Kulissenhebel 8 ist ein Gummi 10 einvulkanisiert, so daß, wenn die starre Welle 6 in die Buchse 7 eingreift, der Kulissenhebel 8 gegen die elastische Kraft des Gummis 10 verdreht werden kann. An einem der Enden weist der Kulissenhebel 8 eine Auflauffläche 12 auf, die beim Einbau in der Nagelvorrichtung mit dem Auflaufbolzen 13 zusammenwirkt. Am gegenüberliegenden Ende weist der Kulissenhebel 8 eine gabelförmige Ausbildung auf. Diese Gabel umgreift den Bolzen 11 des Vorschubkörpers 5, um diesen in der Öffnung 4 des Hammerkopfes zu bewegen.2 the link lever 8 is shown from the side. One recognizes the annular approach 9, which is preferably is in one piece with the link lever 8. Within of the annular extension 9 is the star-shaped Socket 7, which has a triangular recess in order the shaft 6, which is firmly connected to the hammer head 3, take. Between the star-shaped socket 7 and the annular approach 9 and the recess behind it a rubber 10 is vulcanized into the link lever 8, so that when the rigid shaft 6 engages the bushing 7, the link lever 8 against the elastic force the rubber 10 can be rotated. At one of the ends the link lever 8 has a ramp surface 12 which when installing in the nailing device with the ramp pin 13 cooperates. At the opposite end the Link lever 8 has a fork-shaped design. This Fork engages around the bolt 11 of the feed body 5 to move it in the opening 4 of the hammer head.

Die Fig. 3 zeigt einen Querschnitt durch den Kulissenhebel 8 mit dem ringförmigen Ansatz 9, der sternförmigen Buchse 7 und dem dazwischen einvulkanisierten Gummi 10.3 shows a cross section through the link lever 8 with the annular approach 9, the star-shaped Bushing 7 and the vulcanized rubber 10 therebetween.

In Fig. 4 ist die Nagelvorrichtung in jener Position gezeigt, bei der gerade ein Nagel 16 eingeschlagen wird, d.h., der auf dem Lagerbolzen bzw. im vorliegenden Fall auch Auflaufbolzen 13 gelagerte Schlagbolzen 14 befindet sich in seiner tiefsten Position im Schlagkanal 15 und schlägt den darin befindlichen Nagel 16 aus der Vorrichtung in das zu nagelnde Material. Der Vorschubkörper 5 ist über den Bolzen 11 vom Kulissenhebel 8 in der Öffnung 4 des Hammerkopfes 3 zurückgeschoben, so daß weder der Vorschubkörper 5 noch die daran befestigten Vorschubklauen 17 den Schlagbolzen 14 beim Herausschlagen des Nagels 16 behindern. Der zwischen der sternförmigen Buchse 7 und dem ringförmigen Ansatz 9 sowie der dahinterliegenden Ausnehmung des Kulissenhebels 8 befindliche Gummi 10 ist in dieser Position gespannt und sorgt für eine Rückstellung des Vorschubkörpers 5 beim Entlasten der Nagelvorrichtung, wobei die auf dem Vorschubkörper 5 angebrachten Vorschubklauen 17 Nägel 18 in Richtung Schlagkanal 15 führen.In Fig. 4 the nail device is shown in that position where a nail 16 is being driven in, i.e. on the bearing pin or in the present case also firing pin 13 mounted firing pin 14 is located in its lowest position in the blow channel 15 and knocks the nail 16 in it out of the device into the material to be nailed. The feed body 5 is about the pin 11 of the link lever 8 in the opening 4 of the hammer head 3 pushed back, so that neither Feed body 5 still the feed claws attached to it 17 the firing pin 14 when knocking out the nail 16 hinder. The between the star-shaped socket 7 and the annular approach 9 and the one behind it Recess of the link lever 8 is rubber 10 cocked in this position and ensures a reset the feed body 5 when relieving the nail device, which are attached to the feed body 5 Feed claws 17 nails 18 in the direction of the blow channel 15 to lead.

In Fig. 5 ist detailliert die Vorschubeinrichtung von der anderen Seite gesehen dargestellt. Der Schlagbolzen 14 befindet sich auch in dieser Darstellung in seiner tiefsten Position im Schlagkanal 15 im Hammerkopf 3. Der Nagel 16 wird in diesem Moment in das zu nagelnde Material eingeschlagen. Kurz bevor es zum Einschlagen des Nagels 16, der sich im Schlagkanal 15 befindet, kommt, d.h. kurz bevor der Schlagbolzen 14 seine tiefste Position im Schlagkanal erreicht, wird der Nagel 16 freigegeben, indem der Vorschubkörper 5 zurückgezogen wird, so daß in dem Moment des Einschlagens weder die vordere Kante des Vorschubkörpers 5 noch die vorderste Vorschubklaue 17 in den Schlagkanal 15 ragen, so daß der Schlagbolzen 14 beim Einschlagen des Nagels 16 nicht behindert wird. Die weiteren Nägel 18 sind mit Verbindungsdrähten 19 zu einem Nagelband verbunden und die Nagelköpfe werden in einer Nut 21, die zumindest im Hammerkopf 3 vorgesehen ist, geführt. In Fig. 5 is the feed device of the shown on the other side. The firing pin 14 is also at its deepest in this representation Position in the blow channel 15 in the hammer head 3. The nail 16 is now in the material to be nailed taken. Just before it hit the nail 16, which is located in the blow channel 15, i.e. short before the firing pin 14 in its lowest position Impact channel reached, the nail 16 is released by the feed body 5 is withdrawn so that in at the moment of impact, neither the leading edge of the Feed body 5 still the foremost feed claw 17 in the impact channel 15 protrude so that the firing pin 14 at Hammering the nail 16 is not hindered. The others Nails 18 are with connecting wires 19 to one Nail band connected and the nail heads are in one Groove 21, which is provided at least in the hammer head 3, out.

In der Fig.6 sieht man im Schlagkanal 15 den Schlagbolzen 14, der in seiner tiefsten Position im Schlagkanal 15 ist, d.h. es ist, wie in Fig. 5, der Moment dargestellt, in dem gerade ein Nagel eingeschlagen wurde und die Nagelvorrichtung noch nicht entspannt ist. Der Vorschubkörper 5 wird von dem hier nicht dargestellten Kulissenhebel 8 über den Bolzen 11 in zurückgeschobener Position in der Öffnung 4 gehalten. Die Vorschubklauen 17 befinden sich hinter den vordersten drei Nägel 18. Von der anderen Seite werden die Nägel 18 im Bereich ihrer Schäfte von der Rückhaltefeder 23 geführt, die am Magazinunterteil 22 befestigt und abgestützt ist. Bei Entspannung der Nagelvorrichtung geht der Schlagbolzen 14 im Schlagkanal nach oben, der Kulissenhebel wird vom Gummi 10 zurückgestellt und schiebt den Vorschubkörper 5 und damit auch das Nagelband mit den Nägeln 18 nach vorne, sodaß der vorderste Nagel 18 in den Schlagkanal 15 gelangt und der nächstfolgende Nagel 18 vor der Rückhalteklaue 24 positioniert wird. Beim Eintreiben des im Schlagkanal 15 befindlichen Nagels 18 wird der Vorschubkörper 5 wieder nach hinten geschoben, wobei die Rückhalteklaue 24 verhindert, daß die Nägel 18 dabei nach hinten gezogen werden. Die Rückhaltefeder 23 weicht mit den Nägeln 18 aus, damit die Vorschubklauen 17 nach hinten, an den Nägeln 18 vorbei, gezogen werden können.6 shows the firing pin in the firing channel 15 14, which is in its lowest position in the blow channel 15 is, i.e. it is, as shown in Fig. 5, the moment in which a nail has just been hammered in and the nailing device is not yet relaxed. The feed body 5 is from the link lever, not shown here 8 over the bolt 11 in the retracted position in the Opening 4 held. The feed claws 17 are located behind the foremost three nails 18. From the other side are the nails 18 in the area of their shafts from the Retaining spring 23 guided, which is attached to the magazine base 22 and is supported. When the nail device relaxes the firing pin 14 follows in the firing channel above, the link lever is reset by the rubber 10 and pushes the feed body 5 and thus also the nail band with the nails 18 forward so that the foremost Nail 18 gets into the blow channel 15 and the next one Nail 18 positioned in front of the retention claw 24 becomes. When driving in the located in the blow channel 15 Nagels 18, the feed body 5 is back again pushed, the retention claw 24 prevents the nails 18 are pulled backwards. The retention spring 23 dodges with the nails 18 so that the Feed claws 17 to the rear, past the nails 18, can be pulled.

Die Fig.7 zeigt die Aufsicht auf das Magazin einer Nagelvorrichtung, wie es in der EP-A-0 321 440 offenbart ist. Die hier nicht relevanten übrigen Teile der Nagelvorrichtung sowie der Verschlußdeckel für das Magazin sind der einfacheren Darstellung wegen fortgelassen.7 shows the top view of the magazine of a nailing device, as disclosed in EP-A-0 321 440. The remaining parts of the nailing device that are not relevant here and the cover for the magazine are the omitted for ease of illustration.

Im Magazin 2 liegt der Nagelband-Coil 37. Er besteht aus einer Reihe von Nägel 18, die durch zwei übereinanderliegende Verbindungsdrähte 19 zu einem Band verbunden sind. Dargestellt ist der Endbereich des Coils 37, wobei also ein Großteil der Nägel 18 bereits verbraucht ist. Der Magazinboden ist mit 38 bezeichnet. Durch einen analog ausgebildeten Magazindeckel kann das Magazin geschlossen werden, wobei das Nagelband durch eine Öffnung 40 zum, hier nicht dargestellten, Hammerkopf 3 austritt.The nail tape coil 37 is located in magazine 2. It consists of a series of nails 18, which are superimposed by two Connection wires 19 connected to a band are. The end region of the coil 37 is shown, wherein thus a large part of the nails 18 has already been used. The magazine bottom is designated 38. Through a the magazine can be designed analogously be closed, the nail tape through an opening 40 to the hammer head 3 (not shown here) emerges.

Gemäß vorliegender Erfindung ist eine Wickelhülse 41 vorgesehen, die mit dem Coil 37 auf den Achsdorn 42 des Magazins 2 drehbar aufgesteckt ist. Die Wickelhülse 41 weist in einer Ausführung an einer Seite, nämlich an der zum Magazinboden 8 weisenden Seite, eine ringförmige Nut 43 auf, die eine Aufnahme der Nägelköpfe 34 erlaubt. Strichliert mit der Linie 44 ist der Verlauf der Unterseite der Wickelhülse 41 eingezeichnet, wenn nach einer weiteren Ausführung anstelle der Nut 43 die Wickelhülse 41 einfach als Zylinder vorgesehen ist, der so in den Coil 37 eingesteckt ist, daß die Nägelköpfe 34 unterhalb der Wickelhülse 41 liegen, sodaß die Nägelköpfe 34 freigestellt sind.According to the present invention, there is a winding tube 41 provided with the coil 37 on the spindle 42 of the Magazine 2 is plugged rotatably. The winding tube 41 shows in one version on one side, namely on the to the magazine bottom 8 side, an annular groove 43, which allows the nail heads 34 to be received. Dashed with line 44 is the course of the bottom the winding tube 41 is shown if after a another embodiment instead of the groove 43, the winding tube 41 is simply provided as a cylinder, so in the Coil 37 is inserted that the nail heads 34 below the winding sleeve 41 lie so that the nail heads 34 are free are.

Beim Abwickeln des Nagelbandes im Verlaufe der Tätigkeit der Nagelvorrichtung ist durch beide Varianten sichergestellt, daß insbesondere die innerste Lage des Coils 37 durch die zylindrische Fläche der Wickelhülse 41 senkrecht gehalten wird. Dies trifft auch dann zu, wenn der Coil 37 weitgehend abgewickelt ist, wie dies in Fig.7 dargestellt ist.When unwinding the nail tape during the activity the nailing device is ensured by both variants, that in particular the innermost layer of coil 37 through the cylindrical surface of the winding tube 41 perpendicular is held. This also applies if the Coil 37 is largely unwound, as shown in Fig.7 is shown.

In Fig.8 ist ein Schnitt nach der Linie VIII-VIII in Fig.7 dargestellt, wobei auf der linken Seite eine zweite Lage des Coils 37 eingezeichnet ist. Die alternativ vorgesehene ringförmige Nut 43 ist so tief ausgebildet, daß die Nägelköpfe 34 genügend Platz haben.In Figure 8 is a section along the line VIII-VIII in Fig.7 shown, with a second on the left Location of the coil 37 is located. The alternative annular groove 43 is formed so deep that the nail heads 34 have enough space.

Der Nagelband-Coil 37 kann entweder schon von Anbeginn an auf die Wickelhülse 41 aufgewickelt sein, sodaß der Coil 37 mit der Wickelhülse 41 aufgesteckt wird. Die Wickelhülse 41 kann aber auch getrennt als Zubehörteil zur Nagelvorrichtung vorgesehen werden, wobei die Wickelhülse 41 in den vorbereiteten Nagelband-Coil 37 mittig eingesteckt wird.The nail tape coil 37 can either from the beginning be wound on the winding tube 41 so that the coil 37 is attached with the winding tube 41. The winding tube 41 can also be used separately as an accessory for the nailing device are provided, the winding tube 41 inserted in the center of the prepared nail coil coil 37 becomes.

Die Höhe der Wickelhülse 41 entspricht etwa der Höhe des Nagelbandes. Jedenfalls muß gewährleistet sein, daß die Nägel 18 der inneren Coil-Lage bzw. deren beide Verbindungsdrähte 19 auf der Zylinderfläche der Wickelhülse 41 aufliegen.The height of the winding tube 41 corresponds approximately to the height of the Nail tape. In any case, it must be guaranteed that the Nails 18 of the inner coil layer or their two connecting wires 19 on the cylindrical surface of the winding tube 41 rest.

Wenn gemäß einer Variante die Drähte 19 vergütet sind, wird ihre Härte verändert und die Durchbiegung und die Stauchung sind begrenzt. Dies bedeutet aber wiederum, daß die Bewegungsmöglichkeiten der einzubringenden Nägel 18 besser kontrollierbar und vorhersehbar sind und ein einwandfreier Vorschub des Nagelbandes gewährleistet ist.If according to a variant the wires 19 are tempered, their hardness is changed and the deflection and the Squeezes are limited. But this in turn means that the movement possibilities of the nails to be inserted 18 are more controllable and predictable and a flawless one Feeding the nail tape is guaranteed.
