- the driving piston is mounted in a latch that can be moved and the housing has a holding element with a support shoulder that at least partially overlaps the latch in the engaging position.
- the driving piston In the case of powder-operated setting tools with a driving piston for transferring the powder force to the setting fastener, the driving piston must be moved backwards in the ready-to-fire position in a guide bush after the driving-in process for the next setting process.
- a latch is provided in the housing of the setting device which protrudes into the axial displacement path of a radially projecting shoulder of the driving piston.
- the latch is held in the protruding engagement position via a support shoulder of a housing-side holding member.
- the bolt must be disengageable, which is made possible by removing the holding element designed as a screw.
- the removal of the holding member requires the use of an auxiliary tool and moreover requires because of the need for complete Unscrewing the holding member requires considerable manipulation; this also applies to the insertion or fixing of the bolt by the holding member.
- the invention has for its object to enable the removal and insertion of the bolt in a setting tool with the return of a driving piston serving engaging bolt without auxiliary tools and without any significant manipulation effort.
- the holding member is designed as an inner contour which is rotatable about the axis of the driving piston and encompasses the housing and comprises the support shoulder and is interrupted by an opening which corresponds at least to the radial projection of the overlapped locking part.
- the ring-shaped holding member Due to the rotatability of the ring-shaped holding member about the axis of the driving piston, the latter can be brought into different rotational positions with the inner contour serving as a supporting shoulder in the overlapping or non-overlapping position of the bolt without an auxiliary tool being required for this. In the respective rotational position, the holding member can be held in position, for example, by friction.
- the holding member is designed as a ring encompassing the housing with an inner contour which forms the support shoulder and is interrupted by an opening which corresponds at least to the radial projection of the overlapping locking part.
- a ring-shaped holding member does not require any special guiding means, since the ring encompasses the housing in a concentric manner. It is only necessary to axially fix the ring in relation to the housing.
- the latch can essentially have a bar shape, for example, one end of the bolt is hooked into the housing, while the opposite end is held down by gripping over the support shoulder of the ring and thereby fixing the bolt in the engagement position.
- a spring element acting on the underside of the bolt enables the bolt to be automatically disengaged when the opening is brought into congruence with the bolt.
- a locking device is advantageously provided to lock the holding member in rotation.
- the locking device is expediently formed by latching bodies, such as balls, cams or the like, which are immersed in latching depressions by spring force.
- the setting tool according to FIG. 1 has a housing designated overall by 1.
- the housing 1 consists of an outer shell 2 with a laterally protruding handle 3 and a tubular chuck body 4 fixed in the outer shell 2.
- a trigger 5 is displaceably mounted in the handle 3, which acts to trigger the ignition process on an ignition mechanism, not shown, which is known per se .
- a guide bushing designated overall by 6, is slidably mounted, under contact pressure conditions of the setting device for attaining the ignition ready position is shifted towards a closure body 7 fixed on the housing side.
- This displacement of the guide bush 6 takes place against spring force by a tensioning pin 8 seated in the guide bush 6 acting on a compression spring of the ignition mechanism which is supported in the housing 1 on the rear (not shown).
- An ignition pin 9 of the ignition mechanism is slidably mounted in the closure body 7, an ignition lug 11 being drivable into the position projecting into the front end face of the closure body 7.
- the bearing bore 12 opens into a central bore 13 in which a drive piston, designated overall by 14, is mounted.
- the driving piston 14 consists of a front-side shaft 15 and a rear-side head 16. The transition from the smaller cross-section of the shaft 15 to the larger cross-section of the head 16 forms a shoulder 17.
- the shaft 15 is guided in a mouth part designated overall by 18 and projects into it a mouth bore 19 a.
- the mouth part 18 is inserted in a bushing 21 so as to be axially displaceable to a limited extent, locking jaws 22 being held in engagement with niche-shaped recesses 24 on the mouth part 18 by an annular spring 23.
- the bushing 21 is telescopically displaceable in the chuck body 4 and accommodates the front area of the guide bushing 6 on the inside.
- a cam 25 on the inside of the bushing 21 engages in an axially oriented groove 26 of the guide bushing 6 and can be displaced along the guide bushing up to a stop bolt 27.
- the guide bush 6 has a longitudinal slot 28 which is continuous to the front.
- a bar which is in the engaged position and is designated 29 in total projects with a nose 31 through a window 32 in the chuck body 4 and the longitudinal slot 28 into the axial sliding path of the shoulder 17.
- the bolt 29 is bar-shaped and is supported with the rear end 33 in a recess 34 in the housing 1.
- the opposite front end 35 of the bolt 29 is radially overlapped by a ring comprising the chuck body 4, generally designated 36, so that the bolt 29 is held in the engagement position shown.
- a leaf spring 37 acts on the bolt 29 radially outwards.
- the inner contour of the ring 36 forms a support shoulder 38 which partially surrounds the bolt 29 and is interrupted in the circumferential direction by an opening 39, the clear width of which is slightly larger than the radial projection of the overlapped front end 35 of the bolt 29.
- a locking device consisting of a locking ball 41, a spring ring 42 and a locking recess 43 in the chuck body 4, reliably ensures that the overlapping rotational position of the support shoulder 38 is maintained.
- a support ring 45 seated in the chuck body 4 serves to axially support the ring 36.

Description
Die Erfindung betrifft ein pulverkraftbetriebenes Setzgerät mit einem Gehäuse, einem Treibkolben, der gegenüber einem setzrichtungsseitigen Schaft eine radial abragende Schulter aufweist, und einer gegenüber dem Gehäuse längs der Achse des Treibkolbens verschiebbaren Führungsbüchse für den Treibkolben, wobei im Gehäuse ein im wesentlichen senkrecht zur Achse des Treibkolbens in eine Einrückposition verschiebbarer Riegel gelagert ist und das Gehäuse ein Halteorgan mit einer den Riegel in Einrückposition mindestens teilweise übergreifenden Stützschulter aufweist.The invention relates to a powder-operated setting tool with a housing, a driving piston, which has a radially projecting shoulder relative to a shaft on the setting direction, and a guide bush for the driving piston which can be displaced along the axis of the driving piston relative to the housing, the housing having a substantially perpendicular to the axis of the The driving piston is mounted in a latch that can be moved and the housing has a holding element with a support shoulder that at least partially overlaps the latch in the engaging position.
Bei pulverkraftbetriebenen Setzgeräten mit einem Treibkolben zur Uebertragung der Pulverkraft auf das setzende Befestigungselement muss der Treibkolben nach dem Eintreibvorgang für den nächsten Setzvorgang in einer Führungsbüchse wieder in Zündbereitschaftsstellung nach rückwärts verschoben werden.In the case of powder-operated setting tools with a driving piston for transferring the powder force to the setting fastener, the driving piston must be moved backwards in the ready-to-fire position in a guide bush after the driving-in process for the next setting process.
Bei einem bekannten Setzgerät (CH-PS 553 037) ist hierzu ein im Gehäuse des Setzgerätes gelagerter Riegel vorgesehen, der in die axiale Verschiebebahn einer radial abragenden Schulter des Treibkolbens einragt. Nach dem Eintreibvorgang kommt beim Vorziehen der Führungsbüchse der mit der abragenden Schulter am Riegel aufstehende Treibkolben in den rückwärtigen Teil der Führungsbüchse zu liegen, so dass er samt Führungsbüchse wieder in Zündbereitschaftsstellung zurückverschoben werden kann.In a known setting tool (CH-PS 553 037), a latch is provided in the housing of the setting device which protrudes into the axial displacement path of a radially projecting shoulder of the driving piston. After the driving-in process, when the guide sleeve is pulled forward, the driving piston with the projecting shoulder on the bolt comes to rest in the rear part of the guide sleeve, so that it and the guide sleeve can be moved back to the ignition-ready position.
Der Riegel wird über eine Stützschulter eines gehäuseseitigen Halteorgans in der einragenden Einrückposition gehalten. Beispielsweise zum Austausch des Treibkolbens muss der Riegel ausrückbar sein, was durch Entfernen des als Schraube ausgebildeten Halteorgans ermöglicht wird. Das Entfernen des Halteorgans bedarf des Einsatzes eines Hilfswerkzeuges und erfordert darüberhinaus wegen der Notwendigkeit des vollständigen Herausdrehens des Halteorgans einen erheblichen Manipulationsaufwand; dies trifft auch für das Einsetzen bzw. Festlegen des Riegels durch das Halteorgan zu.The latch is held in the protruding engagement position via a support shoulder of a housing-side holding member. For example, to replace the driving piston, the bolt must be disengageable, which is made possible by removing the holding element designed as a screw. The removal of the holding member requires the use of an auxiliary tool and moreover requires because of the need for complete Unscrewing the holding member requires considerable manipulation; this also applies to the insertion or fixing of the bolt by the holding member.
Der Erfindung liegt die Aufgabe zugrunde, bei einem Setzgerät mit dem Rückführen eines Treibkolbens dienendem einrückbarem Riegel das Entfernen und Einsetzen des Riegels ohne Hilfswerkzeug und ohne nennenswerten Manipulationsaufwand zu ermöglichen.The invention has for its object to enable the removal and insertion of the bolt in a setting tool with the return of a driving piston serving engaging bolt without auxiliary tools and without any significant manipulation effort.
Erfindungsgemäss wird die Aufgabe dadurch gelöst, dass das Halteorgan als um die Achse des Treibkolbens drehbarer, das Gehäuse umfassender Ring mit die Stützschulter bildender, von einem mindestens der Radialprojektion des übergriffenen Riegelteiles entsprechenden Durchbruch unterbrochener Innenkontur ausgebildet ist.According to the invention, the object is achieved in that the holding member is designed as an inner contour which is rotatable about the axis of the driving piston and encompasses the housing and comprises the support shoulder and is interrupted by an opening which corresponds at least to the radial projection of the overlapped locking part.
Durch Drehbarkeit des als Ring ausgebildeten Halteorgans um die Achse des Treibkolbens kann dieses in unterschiedliche Drehstellungen mit der als Stützschulter dienenden Innenkontur in den Riegel übergreifende oder nicht übergreifende Stellung gebracht werden, ohne dass hierzu ein Hilfswerkzeug erforderlich ist. In der jeweiligen Drehstellung kann das Halteorgan beispielsweise durch Reibschluss in Position gehalten werden.Due to the rotatability of the ring-shaped holding member about the axis of the driving piston, the latter can be brought into different rotational positions with the inner contour serving as a supporting shoulder in the overlapping or non-overlapping position of the bolt without an auxiliary tool being required for this. In the respective rotational position, the holding member can be held in position, for example, by friction.
Das Halteorgan ist als das Gehäuse umfassender Ring mit die Stützschulter bildender, von einem mindestens der Radialprojektion des übergriffenen Riegelteiles entsprechenden Durchbruch unterbrochener Innenkontur ausgebildet. Ein ringförmiges Halteorgan erfordert keine besonderen Führungsmittel, da der Ring selbsthaltend das Gehäuse konzentrisch umfasst. Es bedarf lediglich der axialen Festlegung des Ringes gegenüber dem Gehäuse.The holding member is designed as a ring encompassing the housing with an inner contour which forms the support shoulder and is interrupted by an opening which corresponds at least to the radial projection of the overlapping locking part. A ring-shaped holding member does not require any special guiding means, since the ring encompasses the housing in a concentric manner. It is only necessary to axially fix the ring in relation to the housing.
Zum Einsetzen bzw. Entfernen des Riegels wird durch Drehen des Ringes dessen Durchbruch in Deckung mit dem Riegel bzw. mit der Ausnehmung für den Riegel im Gehäuse gebracht. Der Riegel kann im wesentlichen beispielsweise Balkenform aufweisen, wobei das eine Ende des Riegels im Gehäuse eingehängt wird, während das gegenüberliegende Ende durch Uebergreifen der Stützschulter des Ringes niedergehalten und dadurch der Riegel in Einrückposition fixiert wird.To insert or remove the bolt, the opening of the bolt is made to coincide with the bolt or with the recess for the bolt in the housing by rotating the ring. The latch can essentially have a bar shape, for example, one end of the bolt is hooked into the housing, while the opposite end is held down by gripping over the support shoulder of the ring and thereby fixing the bolt in the engagement position.
Durch ein unterseitig auf den Riegel einwirkendes Federelement lässt sich ein automatisches Ausrücken des Riegels erreichen, wenn der Durchbruch in Deckung mit dem Riegel gebracht wird. Um sicherzustellen, dass auch durch Erschütterung des Setzgerätes die Halteposition des Halteorgans beibehalten wird, ist zur Dreharretierung des Halteorgans mit Vorteil eine Arretiereinrichtung vorgesehen. Zweckmässig ist die Arretiereinrichtung durch Rastkörper, wie Kugeln, Nocken oder dgl. gebildet, die durch Federkraft in Rastvertiefungen eintauchen.A spring element acting on the underside of the bolt enables the bolt to be automatically disengaged when the opening is brought into congruence with the bolt. In order to ensure that the holding position of the holding member is maintained even when the setting tool is shaken, a locking device is advantageously provided to lock the holding member in rotation. The locking device is expediently formed by latching bodies, such as balls, cams or the like, which are immersed in latching depressions by spring force.
