Description

Die Erfindung geht aus von einem Bolzensetzgerät gemäß den Oberbegriffen der Patentansprüche 1, 2 und 3, mit dessen Hilfe ein Befestigungsmittel, in der Regel in Form eines Nagels oder Bolzens, gesetzt werden kann. Ein solches Bolzensetzgerät ist aus der DE-A-2 850 273 bekannt. Das Bolzensetzgerät enthält einen Treibkolben, der durch die Treibladungsgase nach Anzündung der Treibladungskartusche angetrieben wird und den Bolzen eintreibt.The invention relates to a bolt-driving tool according to the preambles of claims 1, 2 and 3, with the Help a fastener, usually in the form of a nail or bolt, can be placed. Such a bolt-driving tool is known from DE-A-2 850 273. The bolt gun contains a propellant piston which is driven by the propellant gases after ignition of the propellant cartridge is driven and drives in the bolt.

Derartige Geräte werden zum Anschießen von Montageelementen auf hartem Untergrund verwendet, beispielsweise Stahl oder Beton. Dabei tritt das Problem auf, daß der Untergrund nicht immer die gleiche Härte aufweist. In solchen Fällen müssen Probeschüsse gesetzt werden, um herauszufinden, mit welcher Treibladung das korrekte Ergebnis erreicht werden kann. Da jedoch die Härte des Untergrunds auch innerhalb einer Wand sich ändern kann, führt auch das Setzen von Probeschüssen und die Anwendung unterschiedlich starker Treibladungen nicht zum gewünschten Ergebnis.Such devices are used to shoot assembly elements used on hard surfaces, e.g. steel or Concrete. The problem arises that the subsurface is not always has the same hardness. In such cases Trial shots are made to find out which one Propellant charge the correct result can be achieved. There however, the hardness of the surface also within a wall can change, also leads to the setting of test shots and the use of different levels of propellant charge desired result.

Ebenfalls möglich ist es, die Eintreibenergie durch eine Veränderung der Größe des Anfangsbrennraums für die Treibladung einzustellen. It is also possible to change the driving energy the size of the initial combustion chamber for the propellant charge adjust.

Es ist bereits bekannt (DE-U-89 15 510), ein solches Bolzensetzgerät mit einer Kolbenbremse zu versehen, die am Ende des Bewegungsweges des Kolbens diesen abbremst. Die Bremse kann einen elastisch deformierbaren Ringkörper aufweisen, der sich bei Komprimierung radial aufweitet und somit den Treibkolben gegenüber der Kolbenführung festlegt, wodurch der Treibkolben an dem definierten Ort abgebremst wird.
Weiterhin ist ein pulverkraftbetriebenes Bolzensetzgerät bekannt (DE-A1-28 50 273), bei dem an dem vorderen Ende des Geräts eine Abstützmasse angeordnet ist. Die Abstützmasse weist eine elastische Auflageplatte auf, die eine gute Auflage des Setzgerätes an der Oberfläche des Aufnahmematerials ermöglicht. In axialer Richtung ist zwischen einer Schulter des Laufs und der Abstützmasse ein elastisches Element angeordnet, das den Schlag dämpft.It is already known (DE-U-89 15 510) to provide such a bolt-actuating device with a piston brake which brakes the piston at the end of the movement path. The brake can have an elastically deformable ring body that expands radially when compressed and thus fixes the drive piston relative to the piston guide, as a result of which the drive piston is braked at the defined location.
Furthermore, a powder-operated bolt-setting device is known (DE-A1-28 50 273), in which a support mass is arranged at the front end of the device. The support mass has an elastic support plate which enables the setting tool to rest well on the surface of the receiving material. In the axial direction, an elastic element is arranged between a shoulder of the barrel and the support mass, which dampens the impact.

Bei einem weiteren bekannten Gerät dieser Art (US-A-47 46 047) ist in dem Gerät eine aus elastischem Material bestehende Scheibe angeordnet, die eine Begrenzung des Hubs des Stößels bewirkt. Der Schlag wird dadurch gedämpft und auf das Gehäuse über ein elastisches Element übertragen.In another known device of this type (US-A-47 46 047) is an elastic material in the device Disc arranged, which limit the stroke of the Ram causes. The shock is thereby dampened and on the Transfer housing via an elastic element.

Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Bolzensetzgerät im Hinblick auf die einfache Bedienbarkeit zu verbessern. Es soll mit dem Gerät möglich sein, im Idealfall mit nur einer Größe von Treibladung ohne Probeschüsse Befestigungsmittel auf allen Arten von Untergrund setzen zu können.The invention has for its object a generic bolt-firing device to improve in terms of ease of use. It should be possible with the device, ideally with only one Size of propellant without trial shots fasteners to be able to place on all types of surfaces.

Zur Lösung dieser Aufgabe schlägt die Erfindung ein Bolzensetzgerät mit den im Anspruch 1 genannten Merkmalen vor.To achieve this object, the invention proposes a bolt-setting tool with the features mentioned in claim 1.

Der beim Aufschlagen des Treibkolbens am Ende der Bewegung entstehende Schlag wird durch das erfindungsgemäß vorgesehene Dämpfungselement nochmals gedämpft. Es hat sich herausgestellt, daß diese Dämpfung, die zwischen dem zu befestigenden Material und der Bolzenführung bzw. dem vorderen Teil des Gehäuses angeordnet ist, zu einer weiteren Verbesserung des Verhaltens des Bolzensetzgeräts führt, insbesondere dann, wenn das Bolzensetzgerät ein eingangs erwähntes Bremselement für den Treibkolben aufweist. The one when the driving piston hits at the end of the movement resulting blow is provided by the invention Damping element damped again. It turned out that this damping that is between the to be attached Material and the bolt guide or the front part of the housing is arranged to further improve the Behavior of the fastener driving tool leads, in particular, if the bolt-actuating device has a braking element mentioned at the beginning for the driving piston.

Bolzensetzgeräte müssen bestimmten Vorschriften entsprechen, die einen Mißbrauch des Bolzensetzgeräts verhindern sollen. Eine dieser Vorschriften sagt aus, daß das Gerät nur dann ausgelöst werden kann, wenn es mit einer bestimmten Anpreßkraft gegen die Fläche, an der befestigt werden soll, angedrückt wird. Üblicherweise dient hierzu die Bolzenführung. Die Erfindung schlägt nun in Weiterbildung vor, daß das Dämpfungselement mit dem vorderen Ende der Bolzenführung verbunden ist. Beim Anpressen gegen das zu befestigende Material und beim Aufprall des Treibkolbens auf die Bolzenführung, wenn diese axial verschiebbar ist, kann hier dann praktisch keine Druckstelle entstehen.Bolt-setting tools must comply with certain regulations, which are intended to prevent misuse of the fastener driving tool. One of these regulations states that the device only then can be triggered when it is applied with a certain contact pressure pressed against the surface to be attached becomes. The bolt guide is usually used for this. The invention now proposes in training that the Damping element with the front end of the bolt guide connected is. When pressing against the one to be fastened Material and when the driving piston hits the pin guide, if this is axially displaceable, then here practically no pressure point arise.

Durch das Anordnen des Rückstoßdämpfungselements zwischen den beiden axial verschiebbaren Teilen des Gehäuses wird der beim Setzvorgang auftretende Rückstoß gedämpft, so daß er nicht voll auf die Hand des Bedieners übertragen wird. Durch die Kombination der beiden an unterschiedlichen Stellen des Geräts und zu unterschiedlichen Zeitpunkten wirkenden Dämpfungselemente wird das Gerät für den Benutzer angenehmer in der Handhabung.By placing the recoil damping element between the two axially displaceable parts of the housing, the Setback occurring recoil damped so that it does not fully transferred to the operator's hand. Through the Combination of the two in different places of the Device and damping elements acting at different times the device becomes more comfortable for the user handling.

Die Erfindung schlägt ebenfals ein Bolzensetzgerät mit den im Anspruch 2 genannten Merkmalen vor. The invention also proposes a bolt gun with the Claim 2 above features.

Als Dämpfungsmaterial kann beispielsweise ein Gummielement oder ein Element aus einem anderen Elastomermaterial verwendet werden, beispielsweise Butyl-Kautschuk oder Fluor-Kautschuk. Weiterhin kann faserverstärktes Material, ein Metallgespinst oder ein ähnliches elastisch verformbares Material verwendet werden.A rubber element, for example, can be used as the damping material or an element made of another elastomer material be, for example butyl rubber or fluorine rubber. Furthermore, fiber-reinforced material, a metal web or a similar elastically deformable material be used.

Es ist ebenfalls möglich und wird von der Erfindung vorgeschlagen, daß das Dämpfungselement als Ringelement zwischen zwei die Bolzenführung bildenden Ringteilen eingesetzt und mit diesen verbunden ist. Hier ist dann das Dämpfungselement zwar nicht am vorderen Ende der Bolzenführung angeordnet, es wirkt aber bei der Dämpfung des Schlages und ebenso bei der Dämpfung des Rückstoßes in gleich guter Weise.It is also possible and is proposed by the invention that the damping element as a ring element between two ring parts forming the bolt guide are inserted and connected to them. Then here is the damping element not arranged at the front end of the bolt guide, it but works with the damping of the blow and also with the Damping the recoil in the same good way.

Erfindungsgemäß kann das Bolzenschubgerät derart ausgebildet sein, daß die Bolzenführung, mit der das Dämpfungselement verbunden ist, axial verschiebbar ist.According to the invention, the bolt pushing device can be designed in this way be that the bolt guide with which the damping element is connected, is axially displaceable.

Insbesondere kann vorgesehen sein, daß das Dämpfungselement derart ausgebildet ist, daß es sich bei axialer Druckbeaufschlagung radial erweitert. Dies führt dann nicht nur zu einer Dämpfung in Axialwirkung, sondern kann auch dazu verwendet werden, durch eine Begrenzung der Verformbarkeit eine Begrenzung der Dämpfung und des Dämpfungsweges zu erreichen.In particular, it can be provided that the damping element is designed such that it is under axial pressure radially expanded. This not only leads to damping in axial action, but can also be used become, by limiting the deformability To limit the damping and the damping path.

Insbesondere schlägt die Erfindung vor, daß das Dämpfungselement an der Bolzenführung anvulkanisiert ist. Die Bolzenführung bildet dadurch ein einziges Bauteil.In particular, the invention proposes that the damping element is vulcanized onto the bolt guide. The bolt guide thus forms a single component.

Die Erfindung schlägt in Weiterbildung vor, daß das Dämpfungselement derart angeordnet sein kann, daß es mit seiner radialen Außenseite einer zylindrischen Wand des Gehäuses gegenüberliegend angeordnet ist. Das Dämpfungselement kann dann bei seiner Beaufschlagung mit dieser Wand zusammenwirken, beispielsweise dadurch, daß die Wand die Verformbarkeit des Dämpfungselements begrenzt. Insbesondere kann vorgesehen sein, daß die radiale Außenseite des Dämpfungselements von der zylindrischen Wand einen geringen bis keinen radialen Abstand aufweist. In Verbindung mit der radialen Aufweitung und der verschiebbaren Bolzenführung kann das Dämpfungselement dann dazu dienen, einen nach vorne gerichteten Schlag der Bolzenführung durch Verklemmung gegenüber der zylindrischen Wand des Gehäuses oder eines Gehäuse- oder Magazinteils abzubremsen.In a further development, the invention proposes that the damping element can be arranged so that it with his radial outside of a cylindrical wall of the housing is arranged opposite. The damping element can then interact with this wall when it is applied, for example in that the wall deformability limited of the damping element. In particular, can be provided be that the radial outside of the damping element of the cylindrical wall a small to no radial distance having. In connection with the radial expansion and the slidable pin guide can the damping element then serve a forward blow the pin guide by jamming against the cylindrical Wall of the housing or a housing or magazine part slow down.

Das von der Erfindung vorgesehene Bolzensetzgerät führt dazu, daß der Vortrieb des Befestigungselements am Ende des Hubes des Treibkolbens zuverlässig stark abgebremst wird, so daß es möglich wird, das Befestigungselement immer mit der maximalen Treibladung einzutreiben. Dies hat den Vorteil, daß das Befestigungselement bei weicherem Untergrund zwar mit größerer Geschwindigkeit eingetrieben wird als bei hartem Untergrund, dennoch aber nicht in das Montagematerial eindringt. Durch die höheren Eintreibgeschwindigkeiten, die auch bei härterem Material erreicht werden können, verbessert sich die Belastbarkeit der Verbindung. Das Gerät braucht vom Benutzer weder über ein Handrad noch in sonstiger Weise auf den jeweiligen Untergrund eingestellt zu werden.The bolt-setting tool provided by the invention leads to that the propulsion of the fastener at the end of the stroke the driving piston is reliably braked strongly so that it possible, the fastener always with the maximum To drive in propellant charge. This has the advantage that the fastener with a softer surface with a larger one Speed is driven in than on hard ground, but does not penetrate the assembly material. By the higher driving speeds, even with harder ones Material can be reached, the resilience improves the connection. The device does not need from the user using a handwheel in any other way on the respective To be set underground.

Erfindungsgemäß kann das von der Erfindung vorgeschlagene Bolzensetzgerät ein Bremselement zum Abbremsen des Kolbens am Ende seiner Schubbewegung aufweisen. Dieses Bremselement kann in ähnlicher oder gleicher Weise aufgebaut sein wie das Dämpfungselement. Das Bremselement hält den Kolben an und überträgt seine Energie auf das Gehäuse. Dies kann dadurch geschehen, daß es sich aufweitet und sich dadurch radial gegenüber der Außenwand verklemmt. Ebenfalls möglich ist es, daß die Kolbenführung einen nach innen gerichteten Flansch zur Anlage des Bremselements aufweist.According to the invention, that proposed by the invention Bolt setting device a braking element for braking the piston on End of its pushing motion. This braking element can be constructed in a similar or the same way as the damping element. The braking element stops the piston and transmits its energy on the case. This can happen that it expands and thereby faces each other radially jammed the outer wall. It is also possible that the piston guide has an inward flange Has system of the braking element.

Durch das Bremselement und das Dämpfungselement, das am vorderen Ende des Gehäuses und/oder der Bolzenführung angeordnet ist, entsteht eine Kombinationswirkung. Durch das Bremselement wird das zu weite Eintreiben des Bolzens zuverlässig verhindert. Die Energie wird aber auf das Gehäuse übertragen. Das Eindringen des nun zusätzlich belasteten Gehäuses und/ oder der Bolzenführung wird durch das Dämpfungselement verhindert.
Die Erfindung schlägt ebenfalls ein Bolzensetzgerät mit den im Anspruch 3 genannten Merkmalen vor. Eine Einrichtung zum Zurückstellen des Treibkolbens ist an sich bekannt (US-A-33 31 546). Diese Feder wird bei der Vorwärtsbewegung des Kolbens gegen Ende von dessen Bewegung stark komprimiert und überträgt den Stoß damit auf das Gehäuse.
Übliche Treibkolben haben einen langen, relativ schmalen Schaft, dessen freies Ende mit dem Kopf des Befestigungsmittels zusammenwirkt. Erfindungsgemäß kann nun vorgesehen sein, daß die Feder als Hülse ausgebildet ist, die den Schaft des The braking element and the damping element, which is arranged at the front end of the housing and / or the bolt guide, produce a combination effect. The brake element reliably prevents the bolt from being driven too far. However, the energy is transferred to the housing. The damping element prevents the housing and / or the bolt guide, which is now additionally loaded, from entering.
The invention also proposes a bolt gun with the features mentioned in claim 3. A device for resetting the driving piston is known per se (US-A-33 31 546). This spring is strongly compressed during the forward movement of the piston towards the end of its movement and thus transmits the shock to the housing.
Usual driving pistons have a long, relatively narrow shaft, the free end of which cooperates with the head of the fastening means. According to the invention it can now be provided that the spring is designed as a sleeve which the shaft of the

Treibkolbens umgibt. Die Hülse ist dabei leicht deformierbar ausgebildet, sie kann beispielsweise auch als Faltenbalg ausgebildet sein. Die Kräfte, die zum Zurückschieben des Treibkolbens erforderlich sind, sind relativ niedrig.Driving piston surrounds. The sleeve is easily deformable trained, it can for example also be designed as a bellows his. The forces that push the piston back are relatively low.

Besonders günstig ist es und wird von der Erfindung vorgeschlagen, die Feder als Druckfeder im Raum zwischen der Bolzenführung und dem Treibkolben anzuordnen. Es ist auch möglich, den Treibkolben mit einer über den Brennraum hinausreichenden rückwärtigen Verlängerung zu versehen und die Rückstellfeder in einem zweiten Raum anzuordnen.It is particularly favorable and is proposed by the invention the spring as a compression spring in the space between the pin guide and to arrange the driving piston. It is also possible, the driving piston with one that extends beyond the combustion chamber rear extension and the Arrange return spring in a second room.

Die Rückstellfeder kann insbesondere als Druckfeder aus einem Elastomermaterial ausgebildet sein. Sie wird daher immer nur auf Druck beansprucht, so daß die Gefahr eines Reißens, wie zum Beispiel unter einer Zugbeanspruchung, verringert wird. Selbst bei einer teilweisen Zerstörung ihrer Form ist die Feder als elastisches Material immer noch vorhanden, so daß eine gewisse Federwirkung immer noch erreicht wird.The return spring can in particular as a compression spring from one Elastomeric material to be formed. Therefore, it always becomes stressed so that the risk of tearing, such as for example under a tensile load. Even if their shape is partially destroyed, that is Spring is still present as an elastic material, so that a certain spring action is still achieved.

Erfindungsgemäß kann vorgesehen sein, daß der Kolben seitliche durch Schlitze der Kolbenführung bzw. des Gehäuses hindurchführende Ansätze aufweist, an denen die Rückstellfedern angreifen, wobei sie in diesem Fall auch als Zugfedern ausgebildet sein können.According to the invention it can be provided that the piston is lateral through slots in the piston guide or the housing Approaches on which the return springs attack, in which case they are also designed as tension springs could be.

Eine als Zugfeder ausgebildete Rückstellfeder kann beispielsweise von einem Ring aus Elastomermaterial gebildet sein.A return spring designed as a tension spring can, for example be formed by a ring made of elastomer material.

Erfindungsgemäß kann vorgesehen sein, die Feder aus miteinander verbundenen einzelnen Schichten herzustellen. Diese einzelnen Schichten können entweder aus dem gleichen oder einem ähnlichen Material bestehen. Der Schichtenaufbau kann dazu dienen, die Feder gegen ein seitliches Verschieben oder seitliches Ausknicken zu sichern. According to the invention, the spring can be made from one another connected individual layers. This individual Layers can either be the same or one similar material exist. The layer structure can do this serve the spring against lateral displacement or lateral Secure buckling.

Insbesondere kann vorgesehen sein, daß die Schichten aus verschiedenen Materialien bestehen, beispielsweise aus abwechselnd härteren und weicheren Materialien.In particular, it can be provided that the layers of different Materials consist, for example, of alternating harder and softer materials.

Es kann vorgesehen sein, die Feder schichtenweise aus einem relativ harten und einem relativ weichen Material aufzubauen, beispielsweise aus harten Ringscheiben und weichen Ringen. In diesem Fall können die härteren Ringscheiben als Bremselement für den Treibkolben dienen, während die weicheren Schichten die Rückstellfeder bilden. Dadurch wird es möglich, das Bremselement und die Rückstellfeder als ein einziges Bauteil herzustellen.It can be provided that the spring is layered from one build relatively hard and a relatively soft material, for example from hard washers and soft rings. In In this case, the harder washers can be used as a braking element serve for the propellant piston, while the softer layers form the return spring. This will make it possible Brake element and the return spring as a single component to manufacture.

Das in Fig. 1 dargestellte Bolzensetzgerät enthält ein Gehäuse 1 mit einem die Setzmechanik aufnehmenden, axial ausgerichteten Teil und einem seitlich angesetzten Griff 2. Der Griff 2 ist als Bügelgriff ausgebildet. Er enthält einen Abzug 3.The bolt gun shown in Fig. 1 contains a housing 1 with an axially aligned receiving mechanism Part and a side handle 2. The Handle 2 is designed as a bow handle. It contains a deduction 3rd

Das Gehäuse 1 enthält einen zylindrischen Innenraum, in dem eine Treibkolbenführung 4 in axialer Richtung um einen bestimmten Betrag verschiebbar geführt ist. Die Verschiebbarkeit der Treibkolbenführung 4 dient zur Sicherung des Geräts gegen Mißbrauch und der Kartuschenzufuhr.The housing 1 contains a cylindrical interior in which a driving piston guide 4 in the axial direction around a certain one Amount is guided. The movability the driving piston guide 4 serves to secure the device against abuse and the supply of cartridges.

In der Treibkolbenführung 4 ist ein Treibkolben 5 axial verschiebbar angeordnet. Der Treibkolben 5 enthält hier einen scheibenartigen Teil 6 mit vergrößertem Durchmesser, der an der Innenseite 7 der zylindrischen Innenöffnung der Treibkolbenführung 4 anliegt. Der Scheibenteil 6 ist am Ende eines zylindrischen Treibkolbenschaftes 8 angeordnet. Ein solcher Stufenkolben ist prinzipiell auch ohne die Stufe, d.h. ohne den scheibenartigen, vergrößerten Teil einsetzbar.A driving piston 5 is axially displaceable in the driving piston guide 4 arranged. The driving piston 5 contains one here disc-like part 6 with an enlarged diameter, the the inside 7 of the cylindrical inner opening of the driving piston guide 4 is present. The disc part 6 is one at the end cylindrical driving piston shaft 8 arranged. Such a In principle, the stepped piston is also without the step, i.e. without the disk-like, enlarged part can be used.

An dem das Befestigungsmittel aufnehmenden vorderen Endbereich ist in dem Gehäuse 1 eine Bolzenführung 9 in Form einer Führungshülse angeordnet. Diese Bolzenführung 9 enthält einen ersten, in das Innere der Kolbenführung 4 eingreifenden zylindrischen Teil und einen zweiten, sich durch die Stirnseite 10 des Gehäuses nach außen erstreckenden Teil. Beide Teile, die im dargestellten Ausführungsbeispiel unterschiedliche Durchmesser aufweisen, was aber nicht erforderlich ist, sind durch einen radial nach außen vorspringenden Flansch 11 voneinander abgesetzt. Der Flansch 11 ist in einer Ringnut 12 des Gehäuses 1 angeordnet, deren axiale Erstreckung größer ist als die Dicke des Flanschs 11. Dadurch kann die Bolzenführung 9 in dem Gehäuse um eine bestimmte Strecke verschoben werden. An der der Stirnseite 10 des Gehäuses 1 abgewandten Stirnfläche 13 des Flanschs 11 liegt die freie Stirnfläche der Treibkolbenführung 4 an.At the front end area receiving the fastener is a bolt guide 9 in the form of a in the housing 1 Guide sleeve arranged. This pin guide 9 contains one first, cylindrical, engaging in the interior of the piston guide 4 Part and a second, through the face 10 of the housing outwardly extending part. Both parts, the different in the illustrated embodiment Have diameters, but this is not necessary by a radially projecting flange 11 from each other discontinued. The flange 11 is in an annular groove 12 of the housing 1 arranged, the axial extent of which is greater is than the thickness of the flange 11. This allows the bolt guide 9 moved in the housing by a certain distance become. At the end 10 of the housing 1 facing away Face 13 of the flange 11 is the free face the driving piston guide 4.

Die Innenöffnung 14 der Bolzenführung 9 dient zur Aufnahme und Halter des Befestigungselements 15, beispielsweise in Form eines Nagels oder Bolzens.The inner opening 14 of the pin guide 9 is used for receiving and holder of the fastener 15, for example in Shape of a nail or bolt.

Im Innenraum der Treibkolbenführung 4 zwischen der Bolzenführung 9 und dem Scheibenteil 6 des Treibkolbens 5 ist ein Ringelement 16 aus Elastomermaterial angeordnet, dessen Außendurchmesser dem Innendurchmesser der Kolbenführung 4 etwa gleich ist und dessen Innendurchmesser etwas größer als der Außendurchmesser des Bolzensteils 8 des Treibkolbens 5 ist. Dieses Ringelement 16, das auch mit der Bolzenführung 9 fest verbunden sein kann, dient als Bremse für den Treibkolben 5. In the interior of the driving piston guide 4 between the pin guide 9 and the disc part 6 of the driving piston 5 is a Ring element 16 made of elastomer material, the outer diameter the inner diameter of the piston guide 4 approximately is the same and its inner diameter is slightly larger than that Outside diameter of the bolt part 8 of the driving piston 5 is. This ring element 16, which is also fixed with the bolt guide 9 can be connected, serves as a brake for the drive piston 5th

Die Bolzenführung 9 enthält an ihrem dem zu befestigenden Material 17 zugewandten Ende ein die Bolzenführung 9 fortsetzendes Dämpfungselement 18, das ebenfalls als Ringelement aus einem Elastomermaterial hergestellt und mit der Bolzenführung 9 fest verbunden ist, beispielsweise durch ein Aufvulkanisieren an der Stirnfläche. Dadurch bildet die Bolzenführung 9 zusammen mit dem Dämpfungselement 18 ein einzelnes Bauteil.The bolt guide 9 contains the material to be fastened on it 17 facing end continuing the bolt guide 9 Damping element 18, which is also a ring element made of an elastomer material and with the bolt guide 9 is firmly connected, for example by vulcanization on the face. This forms the pin guide 9 together with the damping element 18 a single component.

Das Gerät wird wie folgt bedient. Nach Einsetzen des Befestigungsmittels 15 in die Bolzenführung 9 wird das Gerät von dem Benutzer gegen das zu befestigende Material 17 angedrückt. Dieser Druck überträgt sich auf die Bolzenführung 9, die mit Hilfe des Flanschs 11 die Kolbenführung 4 in das Gerät hineinschiebt. Dadurch gelangt in nicht näher zu beschreibender Weise das Patronenlager 19 im hinteren Teil der Treibkolbenführung 4 über die bereitstehende Treibladungspulverkartusche, und die Schlagbolzenfeder wird gespannt. Nach Auslösen des Abzugs 3 wird die Treibladung abgefeuert und der Treibkolben 5 nach vorne bewegt. Das Befestigungsmittel 15 wird dadurch durch das zu befestigende Material 17 hindurch in den Untergrund 20 eingetrieben. Ist die Bewegungsenergie des Treibkolbens 5 am Ende des Setzvorgangs noch nicht aufgebraucht, läuft der Treibkolben 5 auf das als Kolbenbremse wirkende Ringelement 16 auf. Dieses wird komprimiert und weitet sich dadurch radial auf, so daß es relativ ortsfest in der Kolbenführung 4 axial fixiert wird. Die Restenergie wird dadurch auf die Kolbenführung 4 und ggf. das Gehäuse 1 übertragen. Durch den Pufferschlag und eine teilweise axiale Bewegung der Kolbenführung 4 wird ein Teil der Bewegungsenergie auf die Bolzenführung 9 übertragen. Diese Restenergie der Bolzenführung 9 wird dann durch das Dämpfungselement 18 aufgenommen.The device is operated as follows. After inserting the fastener 15 in the bolt guide 9, the device of the User pressed against the material to be fastened 17. This pressure is transferred to the bolt guide 9, the With the help of the flange 11 pushes the piston guide 4 into the device. This leads to a not to be described in more detail Way, the cartridge chamber 19 in the rear part of the driving piston guide 4 via the ready propellant powder cartridge, and the firing pin spring is tensioned. After triggering the trigger 3, the propellant charge is fired and the propelling piston 5 moved forward. The fastener 15 will thereby through the material 17 to be fastened into the Underground 20 driven. Is the kinetic energy of the Driving piston 5 not yet used up at the end of the setting process, the driving piston 5 runs on it as a piston brake acting ring element 16. This is compressed and expanded thereby radially on, so that it is relatively stationary in the piston guide 4 is axially fixed. The residual energy will thereby transferred to the piston guide 4 and possibly the housing 1. Due to the buffer stroke and a partial axial movement the piston guide 4 becomes part of the kinetic energy transferred to the pin guide 9. This residual energy of Bolt guide 9 is then received by the damping element 18.

Fig. 1 zeigt die axiale Position der Bolzenführung 9 in einem Zustand, in dem nicht abgefeuert werden kann. Im Augenblick des Abfeuerns ist jedoch die Bolzenführung 9 nach rechts verschoben, so daß sich das Dämpfungselement 18 innerhalb des vorderen Teils des Gehäuses befindet. Bei axialer Beaufschlagung des Dämpfungselements 18 wird dieses auch radial erweitert, was zu einer auch in axialer Richtung wirkenden Verklemmung zwischen der Bolzenführung 9 und dem Gehäuse 1 führt.Fig. 1 shows the axial position of the bolt guide 9 in one State in which you cannot fire. At the moment of firing, however, the pin guide 9 is shifted to the right, so that the damping element 18 within the front part of the housing. With axial loading of the damping element 18, this is also expanded radially, which leads to a jamming that also acts in the axial direction between the pin guide 9 and the housing 1 leads.

Während bei der Ausführungsform nach Fig. 1 das Dämpfungselement 18 an dem äußeren Ende der Bolzenführung 9 angeordnet ist, zeigt Fig. 2 eine Ausführungsform der Bolzenführung 9, bei der das Dämpfungselement 18 als Ringelement 21 zwischen zwei Teilen der im übrigen sonst genauso aufgebauten Bolzenführung 9 angeordnet ist. Auch hier ist das Ringelement 21 mit seinen äußeren und inneren Abmessungen auf die Bolzenführung 9 abgestimmt.While in the embodiment of FIG. 1, the damping element 18 arranged at the outer end of the pin guide 9 2 shows an embodiment of the bolt guide 9, in which the damping element 18 as a ring element 21 between two parts of the otherwise identical bolt guide 9 is arranged. Here too, the ring element is 21 with its outer and inner dimensions on the bolt guide 9 matched.

Fig. 3 zeigt noch einmal eine Seitenansicht des Treibkolbens 5 mit seinem Schaft 8 in der gleichen Anordnung wie bei der Fig. 1. Auch das als Kolbenbremse wirkende Ringelement 16 aus Elastomermaterial ist in der gleichen Position wie in Fig. 1 dargestellt.Fig. 3 shows again a side view of the driving piston 5 with its shaft 8 in the same arrangement as in the Fig. 1. Also the ring element 16 acting as a piston brake Elastomeric material is in the same position as in FIG. 1 shown.

Zwischen dem Ringelement 16 und dem Scheibenteil 6 des Treibkolbens 5 ist um den Schaft 8 herum eine Hülse 22 aus Elastomermaterial, insbesondere aus Gummi, angeordnet. Die Hülse 22 ist so ausgebildet, daß sie sich bei axialer Stauchung, die durch die Bewegung des Treibkolbens 5 hervorgerufen wird, in dem Raum zwischen dem Scheibenteil 6 und dem Bremselement 16 elastisch verformen kann, wobei sie bei dieser Verformung innerhalb eines geschlossenes Raums eingeschlossen bleibt. Durch die elastische Verformung entwickelt sie Rückstellkräfte, die nach erfolgtem Setzvorgang den Treibkolben 5 in der Kolbenführung 4 wieder in seine in Fig. 1 dargestellte Ausgangsposition zurückführen. Between the ring element 16 and the disk part 6 of the driving piston 5 is a sleeve 22 made of elastomer material around the shaft 8, especially made of rubber. The sleeve 22 is designed to withstand axial compression is caused by the movement of the driving piston 5 in the space between the disk part 6 and the braking element 16 can deform elastically, with this deformation remains enclosed within a closed space. Due to the elastic deformation, it develops restoring forces, the driving piston 5 in the after the setting process Piston guide 4 again in its starting position shown in FIG. 1 lead back.

Fig. 4 zeigt einen teilweisen Längsschnitt durch eine weitere Ausführungsform. Während bei der Ausführungsform nach Fig. 1 die Kolbenführung 4 im Gehäuse 1 verschiebbar ausgebildet ist, sind bei der Ausführungsform nach Fig. 4 ein einstückiges Gehäuse 1 mit einer durch einen zylindrischen Innenraum gebildeten Kolbenführung 23 dargestellt. Zur Herstellung müßte das Gehäuse 1 aus mehreren Teilen aufgebaut sein, was aber aus Gründen der Vereinfachung nicht dargestellt ist. Am Ende der Kolbenführung 23 ist ein nach innen gerichteter Flansch 24 vorhanden, der einen Durchlaß 25 für den Schaft 8 des Treibkolbens 5 aufweist. An der dem Treibkolben 5 zugewandten Seite des Flansch 24 ist das als Ringelement ausgebildete Bremselement 16 angeordnet. Es kann in der Kolbenführung 23 sowohl mit dem Treibkolben 5 verschiebbar als auch an dem Flansch 24 selbst befestigt oder nur anliegend sein. Die Bremswirkung dieses Ringelements 16 geschieht dann einfach durch Anlage an der Seitenfläche des Flanschs 24.Fig. 4 shows a partial longitudinal section through another Embodiment. While in the embodiment according to FIG. 1 the piston guide 4 is slidably formed in the housing 1 is in the embodiment of FIG. 4 are one piece Housing 1 with a cylindrical interior formed piston guide 23 shown. For the production the housing 1 would have to be constructed from several parts, what but is not shown for reasons of simplification. At the The end of the piston guide 23 is an inward one Flange 24 is present, which has a passage 25 for the shaft 8 of the driving piston 5. On the driving piston 5 facing Side of the flange 24 is the ring element Brake element 16 arranged. It can be in the piston guide 23 displaceable both with the driving piston 5 as well the flange 24 attached itself or just be attached. The The braking effect of this ring element 16 then happens simply by contacting the side surface of the flange 24.

Bei der Ausführungsform nach Fig. 4 ist das freie Ende des Gehäuses 1 ebenfalls mit einem Dämpfungselement 26 versehen, das dem Dämpfungselement 18 der Bolzenführung 9 entspricht.4, the free end of the Housing 1 also provided with a damping element 26, which corresponds to the damping element 18 of the pin guide 9.

An dem rückwärtigen Ende der Bolzenführung 9 ist analog zur Vorderseite ein Dämpfungselement 26a angebracht, das bei einem Auflaufen des Kolbens 5 auf das Bremselement 16 die über den Flansch 24 übertragene Restenergie auf die Bolzenführung 9 zusätzlich dämpft.At the rear end of the pin guide 9 is analogous to Front mounted a damping element 26a, which at an impact of the piston 5 on the braking element 16 Residual energy transmitted via the flange 24 to the bolt guide 9 additionally dampens.

Auf das freie, nach außen gerichtete Ende des Dämpfungselements 18, das mit der Bolzenführung 9 verbunden ist, ist eine flache Platte 27 beispielsweise aus Metall aufvulkanisiert. Diese flache Platte 27, die auf die Dämpfungswirkung des Dämpfungselements 18 keinen Einfluß hat, soll beim Zurückschieben der Bolzenführung 9 ein Aufweiten des Endes vom Dämpfungselement 18 unterbinden, was gegebenenfalls zu einem erhöhten Kraftbedarf beim Zurückschieben der Bolzenführung 9 führen würde.On the free, outward end of the damping element 18, which is connected to the bolt guide 9, is a flat plate 27 vulcanized from metal, for example. This flat plate 27, which is based on the damping effect of the Damping element 18 has no influence, should when pushing back the bolt guide 9 a widening of the end of Prevent damping element 18, which may result in a increased power requirement when pushing back the bolt guide 9 would lead.

Fig. 5 zeigt ebenfalls vereinfacht eine Ausführungsform, bei der der Treibkolben 5 über ein zum Beispiel hülsenförmiges Bindeglied 28 mit einem kolbenförmigen Führungszylinder 29 verbunden ist. Dieser Führungskolben 29 enthält zwei diametral angeordnete Ansätze 30, die durch je einen Gehäuseschlitz 31 nach außen ragen. An den außerhalb des Gehäuses 1 liegenden Bereichen der Ansätze 30 ist je eine Feder 32, zum Beispiel aus Elastomermaterial, befestigt, deren jeweils anderes Ende mit einem gehäusefesten Ansatz 33 verbunden ist. Die nur angedeutete Feder 32 ist in diesem Fall als Zugfeder ausgebildet. Der Abstand zwischen dem Treibkolben 5 und dem Führungskolben 29 ist so gewählt, daß der Treibkolben 5 erst am Ende seiner Bewegung den Schlitz 31 erreicht, so daß erst dann das Treibgas dort austreten kann.Fig. 5 also shows a simplified embodiment, at the driving piston 5 via a sleeve-shaped one, for example Link 28 with a piston-shaped guide cylinder 29 connected is. This guide piston 29 contains two diametrically arranged approaches 30, each through a housing slot 31 protrude outwards. On the outside of the housing 1 lying areas of the lugs 30 is a spring 32, respectively Example made of elastomeric material, attached to each other end is connected to a housing-fixed extension 33. The only indicated spring 32 is in this case as a tension spring educated. The distance between the driving piston 5 and the Guide piston 29 is selected so that the drive piston 5 only reached the slot 31 at the end of its movement, so that only then the propellant gas can escape there.

Fig. 6 zeigt eine weitere Ausführungsform, bei der der Treibkolben 5 auf der der Kolbenführung 23 entgegengesetzten Seite mit einer Stange 34 versehen ist, an deren Ende ein kolbenförmiger Führungszylinder 35 angebracht ist. Die Stange 34 greift durch eine Öffnung in einer Querwand 36. Die Querwand 36 begrenzt einen Hohlraum 37, in dem sowohl das Bremselement 16 als auch eine Rückstellfeder 38 untergebracht sind. Das Bremselement 16 ist im dargestellten Beispiel unmittelbar an der Querwand 36 angeordnet, während die Rückstellfeder 38 in dem verbleibenden Raum angebracht ist. Bei Bewegung des Treibkolbens 5 in Fig. 6 nach links bewegt sich der Führungskolben 35 mit und führt in gleicher Weise zu einer Komprimierung der Rückstellfeder 38 und dann zu einem Anliegen an dem Bremselement 16, so daß dieses dann den Treibkolben 15 am Ende seiner Bewegung ebenfalls abbremst. Das Bremselement 16 kann natürlich auch im vorderen Raum gemäß Fig. 1, d.h. zwischen Vorderseite Kolben und Bolzenführung, angeordnet sein, so daß im hinteren Hohlraum 37 sich nur die Rückholfeder befindet.Fig. 6 shows another embodiment in which the driving piston 5 on the side opposite the piston guide 23 is provided with a rod 34, at the end of which a piston-shaped Guide cylinder 35 is attached. The rod 34 reaches through an opening in a transverse wall 36. The transverse wall 36 delimits a cavity 37 in which both the braking element 16 and a return spring 38 are housed. The Brake element 16 is immediately on in the example shown the transverse wall 36 arranged, while the return spring 38 in the remaining space is attached. When moving the Driving piston 5 in FIG. 6, the guide piston moves to the left 35 with and leads to compression in the same way the return spring 38 and then to concern the Brake element 16, so that this then the drive piston 15 on Also decelerated at the end of his movement. The braking element 16 can of course also in the front room according to Fig. 1, i.e. between The front of the piston and the pin guide must be arranged so that only the return spring is in the rear cavity 37 located.

In dem in Fig. 6 dargestellten Beispiel erfolgt das Einbringen der Treibladungskartusche durch radiale Öffnungen 39, könnte jedoch auch in anderer Weise erfolgen. Die Ausführungsform nach Fig. 6 eignet sich insbesondere für eine Kartuschenzuführung mittels einer Drehbewegung des Gehäuses 1, was durch die axiale Bewegung über eine Steuerkurve ähnlich wie bei einer Kugelschreibermechanik erreicht werden kann.In the example shown in FIG. 6, the introduction takes place the propellant charge cartridge through radial openings 39, could also be done in a different way. The embodiment 6 is particularly suitable for a cartridge feed by means of a rotary movement of the housing 1, which is similar due to the axial movement over a control curve as can be achieved with a ballpoint pen mechanism.

Fig. 7 zeigt schematisch und in abfeuerbereitem (gespannten) Zustand eine Ausführungsform, bei der beispielsweise die Anordnung der Fig. 4 Verwendung finden kann. Das Bolzensetzgerät enthält ein zweiteiliges Gehäuse, bestehend aus einem Halterungsteil 40 und einem diesem gegenüber axial verschiebbaren vorderen Gehäuseteil 41, das zugleich der Kolbenführung 4 der vorhergehenden Ausführungsform nach
Fig. 1 entspricht. In dem vorderen Gehäuseteil 41 ist die Bolzenführung 9 angeordnet und die Kolbenführung 23 ausgebildet. Eine zwischen einer Schulter 42 des Halterungsteils und einer Schulter 43 des Vorderteils wirkende Druckfeder sorgt dafür, daß das Gehäusevorderteil 41, wenn es nicht auf dem Untergrund angepreßt wird, sich in einem ausgefahrenen Zustand befindet.FIG. 7 shows schematically and in a ready-to-fire (cocked) state an embodiment in which, for example, the arrangement of FIG. 4 can be used. The bolt-actuating device contains a two-part housing, consisting of a holding part 40 and a front housing part 41 which is axially displaceable relative thereto, which at the same time follows the piston guide 4 of the previous embodiment
Fig. 1 corresponds. The bolt guide 9 is arranged in the front housing part 41 and the piston guide 23 is formed. A compression spring acting between a shoulder 42 of the mounting part and a shoulder 43 of the front part ensures that the housing front part 41 is in an extended state when it is not pressed against the ground.

In dem Halterungsteil 40 befindet sich das Kartuschen-Widerlager 44, an dem sich die Kartusche beim Anpressen des Gehäusevorderteils 41 abstützt. Die angedeuteten Kartuschen 45 werden beim Andrücken in das Kartuschenlager 45a am Ende des Gehäusevorderteils 41 eingeschoben, um dort abgefeuert zu werden.The cartridge abutment is located in the holding part 40 44, on which the cartridge is pressed when pressing the front part of the housing 41 supports. The indicated cartridges 45 are pressed into the cartridge bearing 45a at the end of the Front part 41 inserted to be fired there become.

Die Kartuschenlagerung 44 ist durch einen Stempel 46 geführt, an dessen freiem Ende eine Druckplatte 47 angeordnet ist. Zwischen der Druckplatte 47 und der Stirnwand 48, die den Innenraum des Halterungsteils 40 begrenzt, ist ein weiteres Dämpfungselement 49 angeordnet. Das Dämpfungselement 49 ist ein relativ hartes Elastomermaterial, da beim Anpressen des Gehäusevorderteils 41 und/oder der Bolzenführung 9 zum Spannen des Gerätes das Kartuschen-Widerlager 44 nicht nachgeben soll. Das Dämpfungselement 49 dient zum Abdämpfen des beim Setzvorgang auftretenden Rückstoßes und entlastet dadurch den Bediener des Geräts.The cartridge storage 44 is guided by a stamp 46, at its free end a pressure plate 47 is arranged. Between the pressure plate 47 and the end wall 48, the Limited interior space of the bracket 40 is another Damping element 49 arranged. The damping element 49 is a relatively hard elastomer material, because when pressing the Front housing part 41 and / or the bolt guide 9 for tensioning of the device, the cartridge abutment 44 does not yield should. The damping element 49 serves to dampen the at Recoil and thus relieves the Operator of the device.

Fig. 8 zeigt ein ähnliches Gerät, wobei jetzt nur noch die Unterschiede erwähnt werden.Fig. 8 shows a similar device, now only the Differences are mentioned.

Der bei der Ausführungsform nach Fig. 4 und 7 vorhandene nach innen gerichtete Flansch 24 ist hier als loses Einschraubelement 24' ausgebildet, wobei das Gehäusevorderteil 41 aus zwei miteinander verschraubbaren Teilen aufgebaut ist.The existing in the embodiment of FIGS. 4 and 7 after internally directed flange 24 is here as a loose screw-in element 24 ', wherein the front housing part 41 consists of two parts that can be screwed together are constructed.

Aus Gründen der vereinfachten Darstellung ist bei den Figuren 7 und 8 die Rückstellfeder nicht dargestellt.For the sake of simplified illustration, the figures 7 and 8, the return spring is not shown.

Der Kolbenschaft 8 reicht bei der Ausführungsform nach Fig. 8 in zurückgeschobenem Zustand nur bis etwa zur Außenseite des Flansch 24. Dort ist in einem weiteren zylindrischen Innenraum 50 des vorderen Gehäuseteils 41 ein zweiter Treibkolben 51 angeordnet, der einen scheibenförmigen Führungsbund 52 aufweist. Am Ende des Innenraums 50 ist ein Dämpfungselement 53 angeordnet, das den zweiten Treibkolben 51 an dessen Führungsbund 52 abbremst. Während bei den vorhergehenden Ausführungsformen zwei zeitlich und räumlich hintereinander angeordnete Dämpfungen auftreten, nämlich zum einen die zum Abbremsen des Treibkolbens und zum anderen die der daraus resultierenden Axialbewegung des gesamten beweglichen Systems aus Gehäuse und/oder Bolzenführung, werden bei der Ausführungsform nach Fig. 8 drei solche Dämpfungen hintereinandergeschaltet, wobei das Abbremsen des Treibkolbens 5 und des zweiten Treibkolbens 51 auch gleichzeitig auftreten können. The piston skirt 8 extends in the embodiment according to FIG. 8 when pushed back only to about the outside of the Flange 24. There is another cylindrical interior 50 of the front housing part 41, a second driving piston 51 arranged, the disc-shaped guide collar 52nd having. At the end of the interior 50 there is a damping element 53 arranged, the second driving piston 51 on its guide collar 52 brakes. While in the previous embodiments two chronologically and spatially arranged one behind the other Damping occurs, namely the one for braking of the driving piston and on the other hand that of the resulting ones Axial movement of the entire moving system housing and / or bolt guide, are in the embodiment 8 three such attenuations connected in series, the braking of the driving piston 5 and the second drive piston 51 can also occur simultaneously.

Der Schaft 8 des Treibkolbens 5 kann mit dem zusätzlichen Treibkolben 51 durch einen Bajonettverschluß oder eine sonstige Einrichtung verbunden sein.The shaft 8 of the driving piston 5 can with the additional Driving piston 51 by a bayonet lock or a other facility connected.

Die nun folgenden Figuren 9 bis 11 zeigen verschiedene Möglichkeiten für eine Rückstellfeder. Während bei der vereinfachten Darstellung der Fig. 3 die Rückstellfeder als eine Hülse aus gummielastischem Material abgebildet war, zeigt Fig. 9 als Rückstellfeder einen Ring 54 aus Elastomermaterial, der auf Zug beansprucht wird. Vereinfacht gesagt, ist am Gehäuse des Bolzensetzgeräts ein Haken 55 angebracht, während einer zweiter Haken 56 mit dem Treibkolben 5 verbunden ist. Dies könnte beispielsweise so geschehen wie in der Fig. 5 dargestellt. Bei Vorwärtsbewegung des Treibkolbens 5, in Fig. 9 nach links, wird dieser Ring dann auf Zug beansprucht.The following figures 9 to 11 show different possibilities for a return spring. While with the simplified 3 the return spring as one Sleeve made of rubber-elastic material was shown 9 as a return spring, a ring 54 made of elastomer material, which is claimed on train. Simply put, is a hook 55 is attached to the housing of the bolt-actuating device, connected to the driving piston 5 during a second hook 56 is. This could happen, for example, as in the Fig. 5 shown. When the driving piston 5 moves forward, 9 to the left, this ring is then subjected to tension.

Der Elastomerring 54 könnte auch in dem hinteren Hohlraum 37 der Ausführungsform nach Fig. 6 angeordnet sein.The elastomer ring 54 could also be in the rear cavity 37 the embodiment of FIG. 6 may be arranged.

Fig. 10 zeigt ein Federelement 57, das ähnlich wie bei der Ausführungsform nach Fig. 3 um den Schaft 8 des Treibkolbens 5 herum angeordnet ist. Es ist aus einer Vielzahl von einzelnen Schichten 58 aufgebaut, die jeweils aus Elastomermaterial bestehen und lose oder miteinander verbunden sein können. Beispielsweise durch Verkleben oder Vulkanisieren. Durch die Vielzahl der losen oder miteinander verbundenen Schichten kann eine bessere Formstabilität erreicht werden. Ebenfalls möglich ist es, daß die Schichten aus unterschiedlichem Material bestehen und/oder die Federelemente in konischer oder doppeltkonischer Form ausgeführt sind.Fig. 10 shows a spring element 57, which is similar to the 3 around the shaft 8 of the driving piston 5 is arranged around. It is made up of a variety of individual Layers 58 constructed, each made of elastomer material exist and can be loose or connected. For example by gluing or vulcanizing. Through the Variety of loose or interconnected layers better dimensional stability can be achieved. Likewise it is possible that the layers of different material exist and / or the spring elements in conical or double conical shape.

Weitere Ausführungsformen sind in den Fig. 11 und 12 dargestellt. Fig. 11 ist wiederum nur schematisch zu verstehen. Das in Fig. 11 dargestellte Element enthält einzelne Scheiben 59, die zwecks besserer Führung den gleichen Durchmesser wie der Treibkolben 5 aufweisen und eine Art Kammer bilden. Dazwischen befinden sich die eigentlichen Federelemente, die Elastomerringe 60.Further embodiments are shown in FIGS. 11 and 12. 11 is again only to be understood schematically. The element shown in Fig. 11 contains individual disks 59, the same diameter for better guidance like the driving piston 5 and form a kind of chamber. In between are the actual spring elements, the Elastomer rings 60.

Dieser schichtartige Aufbau ist über einen größeren Bereich fortgesetzt zu denken, wobei aus Gründen der Vereinfachung nur fünf Teilelemente dargestellt sind. Die Elastomerringe 60 können auch in flachen Vertiefungen angeordnet sein, oder es könnten an den Flächen der Scheiben 59 kleine Ansätze vorgesehen sein, um bei einem Zusammendrücken der Einrichtung das vollständige Flachpressen (Blocksetzen) der Elastomerringe 60 zu verhindern. Anstelle oder zusätzlich zu den im Querschnitt runden Elastomerringen 60 könnten auch Ringe 61 mit anderem Querschnitt und anderem Material vorhanden sein. Bei dem Zusammendrücken eines Elements nach Fig. 11 übernehmen die Elastomerringe 60, 61, die sich relativ leicht zusammendrücken lassen, die Rolle der Rückstellfeder. Wird der Treibkolben 5, der mit seinem Schaft 8 durch die Mittelöffnung der Elemente hindurchgreift, durch die Treibladungsgase nach vorne bewegt, so verformen sich zuerst die weicheren Schichten, bis schließlich die harten Scheiben 59 auf Block aneinander zur Anlage kommen, um dann die restliche Energie auf ein vorgelagertes Bremselement 16 zu übertragen.This layered structure is over a larger area to continue thinking, for simplicity's sake only five sub-elements are shown. The elastomer rings 60 can also be arranged in shallow depressions, or it 59 small projections could be provided on the surfaces of the disks to be the one when the device is compressed Complete flat pressing (block setting) of the elastomer rings 60 to prevent. Instead of or in addition to the cross section round elastomer rings 60 could also rings 61 with other Cross-section and other material. When squeezing 11 take over the elastomer rings 60, 61, which compress relatively easily let the role of the return spring. If the driving piston 5, the one with its shaft 8 through the central opening of the elements reaches through, propellant gas moves forward, so the softer layers deform first, until finally the hard disks 59 on block to each other System, then the remaining energy to an upstream To transfer braking element 16.

Auf diese Weise erhält man ein Element, in das als eine Baueinheit sowohl das Bremselement als auch die Rückstellfeder integriert sind. Siehe auch Fig. 12.In this way you get an element in which as a structural unit both the braking element and the return spring are integrated. See also Fig. 12.

Dieses Element kann sowohl in dem Arbeitsraum vor dem Treibkolben 5 als auch dahinter in dem Hohlraum wie bei der Ausführungsform nach Fig. 6 angeordnet sein.This element can be found in the working area in front of the driving piston 5 and behind in the cavity as in the embodiment 6 may be arranged.

Ein Bolzensetzgerät der erfindungsgemäßen Bauweise läßt sich problemfrei mit einem Nagelmagazin an der Vorderseite versehen, so daß dann ein automatisches und schnelles Setzen der Befestigungsmittel gewährleistet ist. A bolt-driving tool of the design according to the invention can be easily provided with a nail magazine on the front, so that an automatic and quick setting of the Fasteners is guaranteed.

Die bisher beschriebene Funktionsweise der Frontdämpfung muß dann auf die Magazinfrontseite übertragen werden, d.h. die Andruckfläche des Magazins wird im Sinne des vorstehenden mit einem erfindungsgemäßen Dämpfungselement versehen.The previously described mode of operation of the front damping must then transferred to the front of the magazine, i.e. the Pressure surface of the magazine is in the sense of the above provided a damping element according to the invention.
