Description

Die Erfindung betrifft gemäß dem Oberbegriff des Patentanspruchs 1 ein pulverkraftbetriebenes Setzgerät mit streifenförmigem Kartuschenmagazin, wobei das Gerät für das Kartuschenmagazin einen im wesentlichen senkrecht zur Gerätelaufachse angeordneten Führungskanal aufweist, in dessen Führungsquerschnitt am Rartuschenmagazin angreifende Vorschubmittel und Rückhaltemittel vorgesehen sind, die mit Ausnehmungen an den Längsrändern des Kartuschenmagazins zusammenwirken.According to the preamble of claim 1, the invention relates to a powder-operated setting tool with a strip-shaped cartridge magazine, the device for the cartridge magazine having a guide channel arranged essentially perpendicular to the device running axis, in the guide cross-section of which feed means and retaining means are provided which engage the recesses on the longitudinal edges and have recesses on the longitudinal edges of the cartridge magazine interact.

Die Erfindung betrifft außerdem ein streifenförmiges Kartuschenmagazin nach dem Oberbegriff des Patentanspruchs 6. Ein derartiges Kartuschenmagazin ist z.B. aus der GB-A-2 146 746 bekannt.The invention also relates to a strip-shaped cartridge magazine according to the preamble of claim 6. Such a cartridge magazine is known, for example, from GB-A-2 146 746.

Aus der DE-C-17 28 198 ist ein gattungsgemäßes pulverkraftbetriebenes Setzgerät mit Zuführeinrichtung für ein streifenförmiges Kartuschenmagazin bekannt. Die für den Transport des Kartuschenmagazins notwendigen Vorschub- bzw. Rückhaltemittel sind in der Nähe der Zündvorrichtung angeordnet. Ein neues Kartuschenmagazin muss somit bis in den Bereich der Zündvorrichtung in den Führungskanal eingeführt werden, um sicherzustellen, dass es von den Vorschub- bzw. Rückhaltemitteln gegen Herausfallen gesichert ist. Damit ist in dieser Position des Kartuschenmagazins das Setzgerät betriebsbereit, was aus Sicherheitsgründen problematisch ist.From DE-C-17 28 198 a generic powder-powered setting tool with a feed device for a strip-shaped cartridge magazine is known. The feed or retention means necessary for the transport of the cartridge magazine are arranged in the vicinity of the ignition device. A new cartridge magazine must therefore be inserted into the guide channel in the area of the ignition device in order to ensure that it is secured against falling out by the feed or retention means. The setting tool is thus ready for operation in this position of the cartridge magazine, which is problematic for safety reasons.

Der im Gehäuse des Setzgerätes angeordnete Zündmechanismus weist einen Zündstift auf, mit dem jeweils eine Kartusche gezündet werden kann. Die bei diesen Kartuschenmagazinen verwendeten Randzünder-Kartuschen können durch den Zündstift, der am Boden irgendwo am Umfangsbereich auf die Kartusche aufschlägt, gezündet werden.The ignition mechanism arranged in the housing of the setting tool has an ignition pin with which a cartridge can be fired in each case. The edge detonator cartridges used in these cartridge magazines can be ignited by the firing pin, which strikes the cartridge anywhere on the floor at the circumferential area.

Da die Längserstreckung begrenzenden Enden des Kartuschenmagazins gleichartig ausgebildet sind, können die Kartuschenmagazine unabhängig von der Ausrichtung beider Enden in den Führungskanal eingeschoben werden. Aus diesem Grunde ist bei Verwendung von Randzünder-Kartuschen sicherzustellen, dass der asymmetrisch angeordnete Zündstift des Zündmechanismus den Zündsatz erreicht. Dies kann nur mit einem umlaufend angeordneten Zündsatz erreicht werden, was die Verwendung von relativ viel Material an Zündsatz erfordert!Since the ends of the cartridge magazine delimiting the longitudinal extent are of the same design, the cartridge magazines can be inserted into the guide channel regardless of the alignment of both ends. For this reason, when using rimfire cartridges, it must be ensured that that the asymmetrically arranged ignition pin of the ignition mechanism reaches the ignition charge. This can only be achieved with a circumferentially arranged primer, which requires the use of a relatively large amount of primer!

Aus der GB-A-2 146 746 ist ein weiteres streifenförmiges Kartuschenmagazin bekannt. Dieses Kartuschenmagazin weist an beiden Enden gebrochene Kanten auf, wobei sich diese gebrochenen Kanten zum freien Ende des Kartuschenmagazins hin unmittelbar an die jeweils letzten Transportöffnungen anschliessen. Die an beiden Enden des Kartuschenmagazins angeordneten gebrochenen Kanten ermöglichen ein lage-undefiniertes Einführen in ein Setzgerät, d.h. das Kartuschenmagazin kann über beide freien Enden in das Setzgerät eingeführt werden.A further strip-shaped cartridge magazine is known from GB-A-2 146 746. This cartridge magazine has broken edges at both ends, these broken edges directly adjoining the last transport openings towards the free end of the cartridge magazine. The broken edges arranged at both ends of the cartridge magazine enable position-undefined insertion into a setting device, ie the cartridge magazine can be inserted into the setting device via both free ends.

Ein aus wirtschaftlichen und sicherheitstechnischen Gründen nur an einer bestimmten Stelle am Umfang des Bodens der Kartusche angeordneter weniger Material erfordernder Zündsatz kann nicht zum Einsatz kommen, da die Schwierigkeit besteht, dass bei falsch eingesetztem Kartuschenmagazin der Zündstift den Zündsatz nicht trifft.A primer that requires less material and is only located at a certain point on the circumference of the bottom of the cartridge for economic and safety reasons cannot be used, since there is a problem that the igniter does not hit the primer if the cartridge magazine is inserted incorrectly.

Der Erfindung liegt die Aufgabe zugrunde, ein Setzgerät einschliesslich Kartuschenmagazin so auszubilden, dass die Kartuschen mit Hilfe des Kartuschenmagazins in einer definierten Lage einsetzbar sind und das Kartuschenmagazin vor dem Erreichen der betriebsbereiten Position gegen Herausfallen gesichert ist.The invention has for its object to design a setting tool including cartridge magazine so that the cartridges can be used in a defined position with the aid of the cartridge magazine and the cartridge magazine is secured against falling out before reaching the ready position.

Erfindungsgemäss wird die Aufgabe dadurch gelöst, dass im Eintrittsbereich des Führungskanals in Vorschubrichtung des Kartuschenmagazins, den Vorschubmitteln und den Rückhaltemitteln vorgelagert, an zwei einander gegenüberliegenden, mit den Längsrändern des Kartuschenmagazins korrespondierenden Seiten gegen Federkraft ausrückbare Sperrorgane in den Führungsquerschnitt des Führungskanals ragen, wobei diese Sperrorgane eine Längserstreckung aufweisen, die grösser ist als die Längserstreckung der am Kartuschenmagazin angeordneten Ausnehmungen und dass das Kartuschenmagazin einführseitig dem Ausrücken der Sperrorgane dienende Steuerkurven aufweist.According to the invention, the object is achieved in that in the inlet area of the guide channel in the feed direction of the cartridge magazine, the feed means and the retaining means, on two opposite sides, corresponding to the longitudinal edges of the cartridge magazine, which can be disengaged against spring force and protrude into the guide cross section of the guide channel, these locking members have a longitudinal extent which is greater than the longitudinal extent of the recesses arranged on the cartridge magazine and that the cartridge magazine has control cams on the insertion side serving to disengage the locking members.

Die auf diese Art ausgebildeten Sperrorgane ragen so weit in den Querschnitt des Führungskanals, dass ein falsches Einsetzen des Kartuschenmagazins nicht möglich ist. Wird das richtige Ende des Kartuschenmagazins dem Führungskanal zugeführt, so werden die Sperrorgane mit Hilfe der am Kartuschenmagazin angeordneten Steuerkurven auseinandergedrückt, so dass das Kartuschenmagazin weiter in den Führungskanal hineingeschoben werden kann.The blocking members designed in this way protrude so far into the cross section of the guide channel that incorrect insertion of the cartridge magazine is not possible. If the correct end of the cartridge magazine is fed into the guide channel, the locking elements are pressed apart with the aid of the control cams arranged on the cartridge magazine. so that the cartridge magazine can be pushed further into the guide channel.

Vorzugsweise sind die Sperrorgane federnde Wandungsteile des Führungskanals. Derartig ausgebildete Sperrorgane sind einfach in der Herstellung, platzsparend und wirtschaftlich herstellbar. Bei der Herstellung der Wandungsteile des Führungskanals muss bei der Materialwahl darauf geachtet werden, dass das Material ein Elastizitätsmodul aufweist, das sich für die erfindungsgemäss ausgebildeten, federnd wirkenden Wandungsteile eignet. Die dem Festhalten des Kartuschenmagazins dienenden Federkräfte werden von den hinausgedrückten Wandungsteilen aufgebracht.The blocking members are preferably resilient wall parts of the guide channel. Locking members designed in this way are simple to manufacture, space-saving and economical to produce. When manufacturing the wall parts of the guide channel, care must be taken when choosing the material that the material has a modulus of elasticity which is suitable for the spring-acting wall parts designed according to the invention. The spring forces that hold the cartridge magazine in place are applied by the wall parts that are pushed out.

Zweckmässigerweise weisen die Sperrorgane Sperrnasen und Rückhaltenocken auf, wobei die Sperrnasen in Vorschubrichtung des Kartuschenmagazins vor den Rückhaltenocken angeordnet sind. Die in den Führungsquerschnitt des Führungskanals ragenden Sperrnasen verhindern das falsche Einschieben des Kartuschenmagazins. Die Sperrnasen weisen bevorzugt eine im wesentlichen rechtwinklig zur Längsachse verlaufende Anschlagfläche auf.The locking members expediently have locking lugs and retaining cams, the locking lugs being arranged in front of the retaining cams in the feed direction of the cartridge magazine. The locking lugs protruding into the guide cross-section of the guide channel prevent the cartridge magazine from being inserted incorrectly. The locking lugs preferably have a stop surface running essentially at right angles to the longitudinal axis.

Der Abstand zwischen Sperrnase und Rückhaltenocke ist derartig abgestimmt, dass die Sperrnasen nicht in die an den Längsrändern des Kartuschenmagazins angeordneten Ausnehmungen gelangen können.The distance between the locking lug and retaining cam is coordinated in such a way that the locking lugs cannot get into the recesses arranged on the longitudinal edges of the cartridge magazine.

Je nach Anwendungsfall gibt es Kartuschenmagazine mit unterschiedlich starken Treibladungen. Wird ein Kartuschenmagazin mit falscher Treibladungsenergie in den Führungskanal eingeschoben, so kann das Kartuschenmagazin wieder aus dem Führungskanal entgegen der Vorschubrichtung herausgezogen werden, so lange die Ausnehmungen an den Längsrändern des Kartuschenmagazines nicht mit den Vorschub- und Rückhaltemitteln zusammenwirken.Depending on the application, there are cartridge magazines with different levels of propellant charge. If a cartridge magazine with the wrong propellant energy is inserted into the guide channel, the cartridge magazine can be pulled out of the guide channel against the feed direction as long as the recesses on the longitudinal edges of the cartridge magazine do not interact with the feed and retention means.

Vorzugsweise ist die Kontur der Rückhaltenockens im wesentlichen kreisabschnittartig ausgebildet. Falls es sich bei der Kontur um einen Teil eines Kreises handelt so entspricht der Radius des Kreises der 0,6- bis 1,3-fachen Längserstreckung einer Ausnehmung am Kartuschenmagazin. Die als kreisabschnittartig ausgebildeten Rückhaltenocken liegen im Mündungsbereich der Ausnehmungen an den Längsrändern der Kartuschenmagazine, so dass die Rückhaltenocken die tiefste Stelle der Ausnehmungen nicht berühren. Durch diese im wesentlichen kreisabschnittartig ausgebildete Kontur des Rückhaltenockens wird ein gutes Ein- bzw. Ausrückverhalten der Sperrorgane gewährleistet.Preferably, the contour of the retaining cam is essentially in the form of a circular segment. If it is If the contour is part of a circle, the radius of the circle corresponds to 0.6 to 1.3 times the longitudinal extent of a recess in the cartridge magazine. The retaining cams designed as a segment of a circle lie in the mouth region of the recesses on the longitudinal edges of the cartridge magazines, so that the retaining cams do not touch the deepest point of the recesses. A good engagement or disengagement behavior of the locking members is ensured by this contour of the retaining cam, which is essentially in the form of a circular segment.

Zweckmässigerweise ist die lichte Weite zwischen den an den Längsrändern des Kartuschenmagazins anliegenden, einander gegenüberliegenden Rückhaltenocken kleiner als die lichte Weite der einander gegenüberliegenden Sperrnasen. Aufgrund der grösseren lichten Weite der Sperrnasen wird das Einrücken der Rückhaltenocken in den Mündungsbereich der Ausnehmungen des Kartuschenmagazines erst möglich. Liegen die Rückhaltenocken im Mündungsbereich der Ausnehmungen, so können die Sperrnasen seitlich an den Längsrändern des Kartuschenmagazines anliegen.The clear width between the retaining cams lying opposite one another on the longitudinal edges of the cartridge magazine is expediently smaller than the clear width of the opposing locking lugs. Due to the larger clear width of the locking lugs, it is only possible to insert the retaining cams into the mouth area of the recesses of the cartridge magazine. If the retaining cams are located in the mouth area of the recesses, the locking lugs can lie laterally on the longitudinal edges of the cartridge magazine.

Vorteilhafterweise werden die Steuerkurven einführseitig von zum freien Ende hin sich der Mitte des Kartuschenmagazins nähernden Einführschrägen an den Längsrandern eines verlängerten Teils des Kartuschenmagazins gebildet. Derartig ausgebildete Einführschrägen lassen sich einfach und wirtschaftlich herstellen und gewährleisten ein gleichmässiges bzw. lineares Auseinanderdrücken der Sperrorgane. Durch die Einführschrägen verjüngt sich das Kartuschenmagazin zum einführrichtungsseitigen Ende. Die verjüngte Breite des Kartuschenmagazins ist schmäler als die lichte Weite zwischen den Sperrnasen bzw Rückhaltenocken, wenn diese in den Führungsquerschnitt des Führungskanals ragen.Advantageously, the control curves are formed on the insertion side by insertion bevels approaching the center of the cartridge magazine towards the free end on the longitudinal edges of an extended part of the cartridge magazine. Such bevels can be produced easily and economically and ensure a uniform or linear pushing apart of the locking members. The cartridge magazine tapers through the insertion bevels to the end on the insertion direction side. The tapered width of the cartridge magazine is narrower than the clear width between the locking lugs or retaining cams if they protrude into the guide cross section of the guide channel.

Durch die Anordnung von Einführschrägen, die an beiden Längsrändern axial zueinander versetzt angeordnet sind, können die Sperrorgane nacheinander aus dem Führungsquerschnitt des Führungskanals hinausgedrückt werden. Dies ist insbesondere dann von Vorteil, wenn die dem Hinausdrücken entgegenwirkenden Federkräfte der als Wandungsteile ausgebildeten Sperrorgane relativ gross sind, so dass ein gleichzeitiges Hinausdrücken beider Sperrorgane einer zu grossen Anstrengung bedarf.The arrangement of insertion bevels which are axially offset from one another on both longitudinal edges means that the locking members can be pushed out of the guide cross section of the guide channel one after the other. This is particularly advantageous if the spring forces counteracting the pushing out are designed as wall parts Blocking organs are relatively large, so that a simultaneous pushing out of both blocking organs requires too much effort.

Vorzugsweise sind an beiden Längsrändern zueinander symmetrisch verlaufend Einführschrägen vorgesehen. Auf diese Weise werden die Sperrorgane gleichzeitig und gleichmässig aus dem Führungsquerschnitt des Führungskanals hinausgedrückt.Insertion bevels are preferably provided which run symmetrically to one another on both longitudinal edges. In this way, the locking members are simultaneously and evenly pressed out of the guide cross section of the guide channel.

Die Längenänderung des Kartuschenmagazins wirkt sich vorteilhaft auf das Entfernen des Kartuschenmagazins aus dem Führungskanal aus. Die Gesamtlänge des Kartuschenmagazins übersteigt die Länge des Führungskanals, so dass das eingeschobene Kartuschenmagazin aus dem Eintrittsbereich oder Austrittsbereich herausragt. Ein Entfernen des Kartuschenmagazines ist somit jederzeit möglich. Die Länge des Führungskanals kann der parallel zum Führungskanal gemessenen Baulänge des Setzgerätes entsprechen.The change in length of the cartridge magazine has an advantageous effect on the removal of the cartridge magazine from the guide channel. The total length of the cartridge magazine exceeds the length of the guide channel, so that the inserted cartridge magazine protrudes from the entry area or exit area. The cartridge magazine can therefore be removed at any time. The length of the guide channel can correspond to the overall length of the setting tool measured parallel to the guide channel.

Ragt das Kartuschenmagazin aus dem Eintrittsbereich heraus, so wird es so weit in den Führungskanal hineingeschoben, bis es im Austrittsbereich aus dem Führungskanal herausragt. Das Kartuschenmagazin ist somit im verlängerten Bereich, in dem die Einführschrägen angeordnet sind, fassbar und aus dem Führungskanal herausziehbar.If the cartridge magazine protrudes from the entry area, it is pushed into the guide channel until it protrudes from the guide channel in the exit area. The cartridge magazine can thus be grasped in the extended area in which the insertion bevels are arranged and can be pulled out of the guide channel.

Die Erfindung wird anhand eines Ausführungsbeispieles näher erläutert. Es zeigen:

Die Fig. 1 zeigt ein pulverkraftbetriebenes Setzgerät, das im wesentlichen aus einem Gehäuse 1, einem Eintreibkolben 2, einem Führungszylinder 3 für den Eintreibkolben 2, einem Sicherungsstift 3a, einem Zündmechanismus 4 mit einem Zündstift 5, einem Auslöser 6 für die Auslösung des Zündmechanismus 4 und einem Handgriff 7 besteht. Ein der Führung eines Kartuschenmagazins 8 mit Kartuschen 8a dienender Führungskanal 9 erstreckt sich durch das Gehäuse 1 und den Handgriff 7.1 shows a powder-operated setting tool which essentially consists of a housing 1, a driving piston 2, a guide cylinder 3 for the driving piston 2, a locking pin 3a, an ignition mechanism 4 with an ignition pin 5, a trigger 6 for triggering the ignition mechanism 4 and a handle 7. A guide channel 9 serving to guide a cartridge magazine 8 with cartridges 8a extends through the housing 1 and the handle 7.

Das von unten in der Vorschubrichtung X in den Führungskanal 9 eingeschobene Kartuschenmagazin 8 wird mit Hilfe der im Führungsquerschnitt des Führungskanals 9 angeordneten Vorschubmittel 10 weitertransportiert und in seiner Lage durch Rückhaltemittel 15 fixiert.The cartridge magazine 8, which is inserted into the guide channel 9 from below in the feed direction X, is transported further with the aid of the feed means 10 arranged in the guide cross section of the guide channel 9 and is fixed in its position by retaining means 15.

Die Zündung der Kartuschen 8a erfolgt mittels eines Zündstiftes 5 des Zündmechanismus 4. Die Auslösung des Zündmechanismus erfolgt über den Auslöser 6. Am Führungszylinder 3 ist ein Sicherungsstift 3a angeordnet, welcher beim Anpressen des Setzgerätes auf das Bauteil A entgegen der Setzrichtung verschoben wird und somit den Zündmechanismus 4 zur Auslösung freigibt.The cartridges 8a are ignited by means of an ignition pin 5 of the ignition mechanism 4. The triggering of the ignition mechanism takes place via the trigger 6. A securing pin 3a is arranged on the guide cylinder 3, which is pushed against the setting direction when the setting tool is pressed onto the component A and thus the setting direction Ignition mechanism 4 releases for triggering.

Während die Fig. 3, 4 und 5 einzelne Abschnitte des Einschiebevorganges des Kartuschenmagazins 8 in den Führungskanal 9 darstellen, zeigt die Fig. 2, wie die in den Führungsquerschnitt des Führungskanals 9 ragenden Sperrorgane 13, 14 dank Sperrnasen 13a, 14a das Einstossen eines verkehrt zugeführten Kartuschenmagazins 8 verhindern.3, 4 and 5 individual sections of the insertion process of the cartridge magazine 8 into the guide channel 9 shows, FIG. 2 shows how the locking members 13, 14 protruding into the guide cross section of the guide channel 9, thanks to locking lugs 13a, 14a, prevent the insertion of a cartridge magazine 8 fed in the wrong way.

Die Sperrorgane 13, 14 sind als federnd wirkende Wandungsteile des Führungskanals 9 ausgebildet. Es muss daher bei der Materialwahl für die Wandungsteile darauf geachtet werden, dass das Elastizitätsmodul den gestellten, federnden Anforderungen entspricht. Durch eine entsprechende konstruktive Ausgestaltung können die Sperrorgane 13, 14 derartig ausgebildet sein, dass keine allzu grosse Kraft aufgewendet werden muss, um die Sperrorgane 13, 14 seitlich aus dem Führungsquerschnitt des Führungskanals 9 hinauszudrücken.The locking members 13, 14 are designed as spring-acting wall parts of the guide channel 9. When choosing the material for the wall parts, care must therefore be taken to ensure that the modulus of elasticity meets the resilient requirements. By means of a corresponding structural design, the blocking elements 13, 14 can be designed such that no excessive force has to be applied in order to push the blocking elements 13, 14 laterally out of the guide cross section of the guide channel 9.

Das Kartuschenmagazin 8 weist als Steuerkurven wirkende beidseits symmetrisch angeordnete Einführschrägen 8c, 8d auf, die von den Längsrändern des Kartuschenmagazins 8 gebildet werden. Beim richtigen Einschieben des Kartuschenmagazins 8 in den Führungskanal 9 gelangen zuerst die Sperrnasen 13a, 14a und anschliessend die Rückhaltenocken 13b, 14b zur Anlage an den Einführschrägen 8c, 8d. Beim weiteren Einschieben des Kartuschenmagazins 8 werden die Sperrorgane 13, 14 radial aus dem Führungsquerschnitt des Führungskanals 9 hinausgedrückt, bis die lichte Weite zwischen den Rückhaltenocken 13b, 14b der Breite des Kartuschenmagazins 8 entspricht.The cartridge magazine 8 has insertion chamfers 8c, 8d, which are symmetrically arranged on both sides and act as control cams and are formed by the longitudinal edges of the cartridge magazine 8. When the cartridge magazine 8 is correctly inserted into the guide channel 9, the locking lugs 13a, 14a and then the retaining cams 13b, 14b come to rest against the insertion bevels 8c, 8d. When the cartridge magazine 8 is pushed in further, the locking members 13, 14 are pressed radially out of the guide cross section of the guide channel 9 until the clear width between the retaining cams 13b, 14b corresponds to the width of the cartridge magazine 8.

Wird das Kartuschenmagazin 8 aus der in Fig. 4 dargestellten Position weiter in Vorschubrichtung X verschoben, so gelangen die Rückhaltenocken 13b, 14b in dem Mündungsbereich zweier Ausnehmungen 8e zur Anlage (Fig. 5). Die Rückhaltenocken 13b, 14b sind kreisabschnittartig ausgebildet, wobei der Radius der sich auf den Kreis des Kreisabschnittes bezieht, der 0,6- bis 1,3-fachen Länge der entsprechenden Ausnehmungen 8e am Kartuschenmagazin 8 entspricht.If the cartridge magazine 8 is shifted further from the position shown in FIG. 4 in the feed direction X, the retaining cams 13b, 14b come to rest in the mouth area of two recesses 8e (FIG. 5). The retaining cams 13b, 14b are designed in the manner of a circular segment, the radius which relates to the circle of the circular segment corresponding to 0.6 to 1.3 times the length of the corresponding recesses 8e on the cartridge magazine 8.

Der Radius des Kreisabschnittes ist zweckmässigerweise gross ausgebildet, so dass ein gutes Einrücken bzw. Ausrücken der Rückhaltenocken 13b, 14b gewährleistet ist, wenn das Kartuschenmagazin 8 manuell oder mit Hilfe der Vorschubmittel 10 in dem Führungskanal 9 weitertransportiert wird.The radius of the circular section is expediently large, so that a good engagement or disengagement of the retaining cams 13b, 14b is ensured if the cartridge magazine 8 is transported further in the guide channel 9 manually or with the aid of the feed means 10.

Betrachtet man den Abstand der Sperrorgane 13, 14 voneinander, wenn diese an den Längsrändern des Kartuschenmagazins 8 anliegen, so ist die lichte Weite zwischen den Sperrnasen 13a, 14a grösser als die lichte Weite zwischen den Rückhaltenocken 13b, 14b.If one considers the distance of the locking members 13, 14 from one another when they rest on the longitudinal edges of the cartridge magazine 8, the clear width between the locking tabs 13a, 14a is greater than the clear width between the retaining cams 13b, 14b.

Die Sperrorgane 13, 14 sind vorzugsweise im Anfangsbereich des Führungskanals 9 angeordnet, so dass zwischen den Sperrorganen 13, 14 und den Vorschubmitteln 10, bzw Rückhaltemitteln 15 ein entsprechender Abstand erreicht wird. Dadurch kann das Kartuschenmagazin 8 in den Führungskanal 9 so weit eingeschoben werden, bis die Rückhaltenocken 13b, 14b in die, den Einführschrägen 8c, 8d am nächsten liegenden Ausnehmungen 8e eingreifen. Auf diese Weise befindet sich das Setzgerät noch nicht im betriebsbereiten Zustand. Das Kartuschenmagazin 9 ist in dieser Position gegen Herausfallen gesichert.The locking members 13, 14 are preferably arranged in the initial region of the guide channel 9, so that a corresponding distance is achieved between the locking members 13, 14 and the feed means 10 or retention means 15. As a result, the cartridge magazine 8 can be pushed into the guide channel 9 until the retaining cams 13b, 14b engage in the recesses 8e closest to the insertion bevels 8c, 8d. In this way, the setting tool is not yet ready for operation. The cartridge magazine 9 is secured in this position against falling out.

Die Länge des Kartuschenmagazines 8 übersteigt die Länge des Führungskanals 9. Im eingeschobenen Zustand ragt das Kartuschenmagazin 8 somit aus dem Ein- oder Austrittsbereich des Führungskanals 9 heraus.The length of the cartridge magazine 8 exceeds the length of the guide channel 9. When inserted, the cartridge magazine 8 thus protrudes from the entry or exit area of the guide channel 9.

Die parallel zum Verlauf des Führungskanals 9 verlaufende Baulänge des Setzgerätes übersteigt die Länge des Führungskanals 9. Der Eintrittsbereich des Führungskanals 9 ist über eine muldenartige Vertiefung 7a im Handgriff 7 erreichbar. Die Grösse dieser muldenartigen Vertiefung 7a entspricht der Grösse eines Daumens, mit dessen Hilfe der aus dem Eintrittsbereich ragende Teil des Kartuschenmagazines 8 in den Führungskanal 9 geschoben werden kann, so dass das Kartuschenmagazin 8 aus dem Austrittsbereich herausragt.The overall length of the setting tool running parallel to the course of the guide channel 9 exceeds the length of the guide channel 9. The entry region of the guide channel 9 can be reached via a trough-like recess 7a in the handle 7. The size of this trough-like recess 7a corresponds to the size of a thumb, with the aid of which the part of the cartridge magazine 8 protruding from the entry area can be pushed into the guide channel 9, so that the cartridge magazine 8 protrudes from the exit area.

Der aus dem Austrittskanal des Führungskanals 9 ragende verlängerte Bereich des Kartuschenmagazines 8 weist eine der besseren Fassbarkeit dienende Profilierung 8f auf.The extended area of the cartridge magazine 8 protruding from the outlet channel of the guide channel 9 has a profiling 8f which improves the graspability.
