Description

Die Erfindung betrifft ein pulverkraftbetriebenes Bolzensetzgerät mit Lauf, Laufmündungsteil und Zündeinrichtung, wobei zum Spannen der Zündeinrichtung ein längs der Laufachse verschiebbarer Spannstössel vorgesehen ist, der mit einem verschiebbar im Laufmündungsteil gelagerten, dessen Stirnseite in entspannter Stellung überragenden Tastglied zusammenwirkt.The invention relates to a powder-operated bolt-actuating device with barrel, barrel mouth part and ignition device, wherein a tensioning plunger which is displaceable along the barrel axis is provided for tensioning the ignition device and which interacts with a displaceably mounted in the barrel mouth part, the end face of which protrudes in the relaxed position.

Aus Sicherheitsgründen weisen pulverkraftbetriebene Bolzensetzgeräte Zündeinrichtungen auf, die erst gespannt sind, wenn das Bolzensetzgerät ausreichend gegen ein Bauteil gepresst wird. Zu diesem Zwecke sind Geräte bekannt, bei welchen der Lauf verschiebbar gelagert ist und beim Anpressen gegen das Bauteil entgegen der Setzrichtung verschoben wird und dabei die Zündeinrichtung spannt.For safety reasons, powder-operated bolt-setting tools have ignition devices which are only cocked when the bolt-setting tool is pressed sufficiently against a component. For this purpose, devices are known in which the barrel is mounted displaceably and is displaced against the setting direction when pressed against the component, thereby tensioning the ignition device.

Nachdem das Laufmündungsteil solch bekannter Bolzensetzgeräte eine relativ grosse Stirnfläche hat, besteht die Möglichkeit, dass der Lauf schon bei unvollständigem Anpressen gegen ein Bauteil bereits die Zündeinrichtung spannt. Um diesem sicherheitstechnischen Nachteil zu begegnen, ist beispielsweise aus der DE-PS 1 503 045 ein Bolzensetzgerät bekannt, bei welchem ein das Laufmündungsteil durchsetzender Spannstössel unter Zwischenschaltung eines Spannstössels zum Spannen der Zündeinrichtung vorgesehen ist. Dank der kleinen Aufstandsfläche des vor dem Spannen der Zündeinrichtung die Stirnseite des Bolzenführungsteiles überragenden Spanngliedes ist eine gezielte Auflage auf dem Bauteil und eine hohe spezifische Flächenpressung zum Spannen der Zündeinrichtung erforderlich. Die sicherheitstechnischen Aspekte werden bei diesem bekannten Bolzensetzgerät somit erfüllt, allerdings unter Inkaufnahme des Nachteiles, dass das Bolzenführungsteil drehschlüssig mit den übrigen Teilen des Bolzensetzgerätes verbunden ist, so dass Zugänglichkeitsprobleme entstehen, weil das in der Projektion grossflächige Laufmündungsteil, beispielsweise nicht gegenüber dem abstehenden Griff des Bolzensetzgerätes in eine anwendungsgerechte Position gebracht werden kann.Since the barrel mouth part of such known bolt-setting devices has a relatively large end face, there is the possibility that the barrel already tensions the ignition device when it is pressed against a component incompletely. In order to counteract this safety-related disadvantage, for example from DE-PS 1 503 045 a bolt-setting device is known, in which a tensioning plunger passing through the barrel mouth part is provided with the interposition of a tensioning plunger for tensioning the ignition device. Thanks to the small contact area of the tendon protruding from the end of the bolt guide part before the ignition device is tensioned, a specific support on the component and a high specific surface pressure are required to tension the ignition device. The safety-related aspects are thus fulfilled in this known bolt-setting tool, however, while accepting the disadvantage that the bolt-guiding part is connected to the other parts of the bolt-setting tool in a rotationally locking manner, so that accessibility problems arise because the projection is large Muzzle part, for example, can not be brought into a position suitable for the application relative to the protruding handle of the bolt-actuating device.

Der letztgenannte Nachteil, dh die anwendungsgerechte Ausrichtung eines Bolzenführungsteiles gegenüber den übrigen Teilen des Bolzensetzgerätes ist bei dem aus der DE-OS 36 06 514 bekannten Bolzensetzgerät gelöst, allerdings unter Inkaufnahme des eingangs geschilderten Sicherheitsnachteiles, indem bei diesem bekannten Bolzensetzgerät wiederum mit dem Lauf die Zündeinrichtung gespannt wird.The last-mentioned disadvantage, that is, the application-oriented alignment of a bolt guide part with respect to the remaining parts of the bolt-firing device is solved in the bolt-firing device known from DE-OS 36 06 514, however, while accepting the safety disadvantage described at the outset, in this known bolt-firing tool again by the ignition device with the barrel is excited.

Der Erfindung liegt die Aufgabe zugrunde, ein Bolzensetzgerät zu schaffen, das einerseits den sicherheitstechnischen Aspekten in Bezug auf das Spannen der Zündeinrichtung Rechnung trägt und andererseits einen ungehinderten Einsatz auch an schwer zugänglichen Stellen ermöglicht.The invention has for its object to provide a bolt-actuating device that takes into account the safety aspects relating to the tensioning of the ignition device on the one hand and on the other hand enables unimpeded use even in places that are difficult to access.

Erfindungsgemäss wird die Aufgabe dadurch gelöst, dass das Laufmündungsteil gegenüber dem Lauf um dessen Achse verdrehbar gelagert ist und zwischen Spannstössel und Tastglied eine längs der Laufachse verschiebbare Hülse angeordnet ist, deren eine Stirnseite mit dem Spannstössel und deren andere Stirnseite mit dem Tastglied zusammenwirkt.According to the invention the object is achieved in that the barrel mouth part is rotatably mounted relative to the barrel about its axis and a sleeve which is displaceable along the barrel axis and whose one end face cooperates with the tension ram and the other end face cooperates with the probe member is arranged between the tensioning plunger and the feeler member.

Die Anordnung der verschiebbaren Hülse zwischen Spannstössel und Tastglied stellt sicher, dass das Tastglied in jeder beliebigen Drehstellung des Laufmündungsteiles der Verschiebung des Spannstössels und damit der Spannung der Zündeinrichtung dienen kann. Damit wirkt die eine Stirnseite der Hülse immer mit dem Spannstössel und die andere Stirnseite mit dem Tastglied zusammen.The arrangement of the displaceable sleeve between the plunger and the feeler element ensures that the feeler element can be used in any rotational position of the barrel mouth part to move the tendon and thus the tension of the ignition device. So that one end of the sleeve always interacts with the clamping plunger and the other end with the feeler.

Die vorgenannten Voraussetzungen sind insbesondere dann gegegeben, wenn die dem Laufmündungsteil zugewandte Stirnseite der Hülse in der axialen Projektion der Bahn liegt, welche das Tastglied beim Verdrehen des Laufmündungsteiles um die Laufachse beschreibt. Dabei umgibt die Hülse den Lauf vorzugsweise konzentrisch.The above-mentioned requirements are met in particular when the end face of the sleeve facing the barrel opening part lies in the axial projection of the path which the feeler describes when rotating the barrel mouth part around the barrel axis. The sleeve preferably surrounds the barrel concentrically.

Die Erfindung wird nachstehend anhand einer Zeichnung, die ein Ausführungsbeispiel wiedergibt, näher erläutert. Es zeigen:

  • Fig. 1 ein Bolzensetzgerät in Zündbereitschaftsstellung, teilweise im Längsschnitt;
  • Fig. 2 den Vorderbereich des Bolzensetzgerätes nach Fig. 1, in Ruhestellung.
The invention is explained below with reference to a drawing which shows an embodiment. Show it:
  • Figure 1 shows a bolt gun in the ignition readiness position, partially in longitudinal section.
  • Fig. 2 shows the front area of the bolt gun according to Fig. 1, in the rest position.

Das Bolzensetzgerät verfügt über ein Gehäuse 1 mit einem seitlich abragenden Handgriff 1a. Im Handgriff 1a ist ein Trigger 2 gelagert. Im vorderen Bereich des Gehäuses 1 ist ein Lauf 3 verschiebbar angeordnet. An den Lauf 3 schliesst vorderseitig ein Laufmündungsteil 4 an. Der axial unverschieblichen, um die Achse des Laufes 3 verdrehbaren Halterung des Laufmündungsteiles 4 dient ein Riegel 5. Dieser sitzt in einem Durchbruch 3a des Laufes 3 und wird von einer Ringfeder 6 in Eingriff mit einer Ringnut 4a des Laufmündungsteiles 4 gehalten. Der Dreharretierung des Laufmündungsteiles 4 in beliebiger Drehstellung dient ein im Laufmündungsteil 4 sitzender Rastbolzen 7, der von einer Druckfeder 8 gegen die Rastvertiefungen 3b aufweisende vordere Stirnseite des Laufes 3 gedrückt wird. Im Laufmündungsteil 4 ist ein stabförmiges Tastglied 9 verschiebbar gelagert, welches das Laufmündungsteil 4 wechselweise entweder nach vorne oder nach hinten überragt. Die Verschiebbarkeit des Tastgliedes 9 wird durch einen im Laufmündungsteil 4 sitzenden Querstift 11, der in eine Auskehlung 9a des Tastgliedes 9 einragt, begrenzt.The bolt gun has a housing 1 with a laterally projecting handle 1a. A trigger 2 is mounted in the handle 1a. In the front area of the housing 1, a barrel 3 is slidably arranged. A barrel mouth part 4 connects to barrel 3 on the front. The axially immovable, rotatable about the axis of the barrel 3 holder of the barrel mouth part 4 serves a bolt 5. This sits in an opening 3a of the barrel 3 and is held by an annular spring 6 in engagement with an annular groove 4a of the barrel mouth part 4. The locking of the barrel mouth part 4 in any rotational position is served by a locking bolt 7 seated in the barrel mouth part 4, which is pressed by a compression spring 8 against the locking recesses 3b having the front end face of the barrel 3. In the barrel mouth part 4, a rod-shaped pushbutton 9 is slidably mounted, which alternately projects over the barrel mouth part 4 either to the front or to the rear. The displaceability of the sensing element 9 is limited by a transverse pin 11 seated in the barrel mouth part 4, which protrudes into a groove 9a of the sensing element 9.

Rückwärtig zum Tastglied 9 ist zwischen dem Lauf 3 und dem Gehäuse 1 eine den Lauf 3 konzentrisch umgebende Hülse 12 verschiebbar gelagert. Deren vordere dh setzrichtungsseitige Stirnseite überdeckt sich in Axialprojektion mit der rückwärtigen Stirnseite des Tastgliedes 9.To the rear of the pushbutton 9 there is a sleeve 12 concentrically surrounding the barrel 3 between the barrel 3 and the housing 1 slidably mounted. The front face, ie the face on the setting direction, overlaps in axial projection with the rear face of the feeler element 9.

Im Lauf 3 und im Laufmündungsteil 4 ist ein Treibkolben 13 verschiebbar gelagert. In die den Treibkolben 13 aufnehmende Laufbohrung 3c mündet rückwärtig ein Kartuschenlager 3d. Der Lauf 3 stützt sich in Zündbereitschaftsstellung unter Anpressdruck an einem Bauteil 14 ab und liegt rückwärtig an einem im Gehäuse 1 abgestützten Verschlussteil 15 an. Eine Zündeinrichtung 16 mit einem Zündstift 17, der im Verschlussteil 15 verschiebbar gelagert ist, und einer Zündfeder 18 befindet sich im rückwärtigen Gehäusebereich des Gehäuses 1. Ein vom Zündstift 17 seitlich abragender Arm 17a wirkt für das Spannen der Zündeinrichtung 16 mit einem längs der Laufachse verschiebbaren, an der Hülse 12 aufstehenden Spannstössel 19 zusammen.In the barrel 3 and in the barrel mouth part 4, a driving piston 13 is slidably mounted. A cartridge bearing 3d opens into the rear bore 3c receiving the driving piston 13. The barrel 3 is supported in the ready-to-ignite position under contact pressure on a component 14 and bears on the back against a closure part 15 supported in the housing 1. An ignition device 16 with an ignition pin 17, which is mounted displaceably in the closure part 15, and an ignition spring 18 is located in the rear housing area of the housing 1. An arm 17a, which projects laterally from the ignition pin 17, acts for tensioning the ignition device 16 with a slide that can be moved along the barrel axis , on the sleeve 12 upright ram 19 together.

Beim Anpressen des Setzgerätes gegen das Bauteil 14 durch Druckausübung auf den Handgriff 1a wird zuerst das in Ruhestellung (Fig. 2) das Laufmündungsteil 4 überragende Tastglied 9 im Laufmündungsteil 4 entgegen der Setzrichtung verschoben. Das Tastglied 9 überträgt die Verschiebebewegung auf die Hülse 12, die ihrerseits den Spannstössel 19 entgegen der Setzrichtung gegen die Kraft der Zündfeder 18 verschiebt. Durch weiteres stärkeres Anpressen des Setzgerätes wird in der Folge auch das Laufmündungsteil 4 zusammen mit dem Tastglied 9 entgegen der Setzrichtung aus der in Fig. 2 gezeigten Ruhestellung in die der Fig. 1 entnehmbare Zündbereitschaftsstellung verschoben. Auch dieser Verschiebeweg wird zum Spannen der Zündeinrichtung 16 vom Tastglied 9 über die Hülse 12 und den Spannstössel 19 übertragen. Durch Ausrücken des Armes 17a aus der Axialprojektion des Spannstössels 19 kann der Zündstift 17 zum Zünden einer Kartusche freigegeben werden. Für den neuerlichen Angriff des Spannstössels 19 am zum Zünden in Setzrichtung gewanderten Arm 17a des Zündstiftes 17 ist eine den Stössel in Setzrichtung treibende Feder 21 vorgesehen.When the setting tool is pressed against the component 14 by exerting pressure on the handle 1a, the pushbutton 9 projecting beyond the barrel mouth part 4 in the rest position (FIG. 2) is first displaced in the barrel mouth part 4 against the setting direction. The feeler element 9 transmits the displacement movement to the sleeve 12, which in turn displaces the tensioning plunger 19 against the setting direction against the force of the ignition spring 18. By further pressing the setting tool further, the barrel mouth part 4, together with the pushbutton 9, is subsequently moved against the setting direction from the rest position shown in FIG. 2 to the ignition ready position shown in FIG. 1. This displacement path is also transmitted for tensioning the ignition device 16 from the sensing element 9 via the sleeve 12 and the tensioning plunger 19. By disengaging the arm 17a from the axial projection of the plunger 19, the firing pin 17 can be released to ignite a cartridge. For the renewed attack of the tensioning plunger 19 on the arm 17a of the ignition pin 17 which has moved in the setting direction for ignition, a spring 21 driving the plunger in the setting direction is provided.

Das Laufmündungsteil 4 kann zusammen mit dem Tastglied 9 in beliebiger Drehstellung gegenüber dem Lauf 3 eingesetzt werden, da das Tastglied 9 stets die Anpresskraft zum Erlangen der Zündbereitschaftsstellung auf die ringförmige Stirnseite der Hülse 12 zu übertragen vermag.The barrel mouth part 4 can be used together with the feeler element 9 in any rotational position relative to the barrel 3, since the feeler element 9 can always transmit the contact pressure to achieve the ignition-ready position on the annular end face of the sleeve 12.
