Definitions
- the invention relates to a spray gun with a handle, a trigger arm rotatably mounted near its upper end and extending only along the upper part of the handle, and a locking element which is arranged at the lower end of the trigger lever and from a release position is displaceable outside the path of the lower end of the trigger in a locking position in this path.
- Spray or spray guns are used to apply powdery materials or liquid materials, such as paint or varnish, to an object to be coated.
- the pistol is actuated by moving the trigger lever with the index finger of the hand gripping the handle.
- the trigger must be secured against unintentional triggering. If such a locking element is present, the trigger must first go through an idle stroke before the actuated valve or the like may be actuated.
- the idle stroke takes into account the play in the area of the locking element and certain manufacturing and Material tolerances. If the idle stroke is too small, control can take place due to the instability of the components. If a sufficient idle stroke is selected, the actual working stroke can be shortened so much that the maximum amount of material is no longer ejected.
- a generic spray or spray gun is known from DE-B2-2 102 252.
- the locking element consists of a rotatable part which is arranged between the lower part of the trigger and the upper part of the handle.
- the trigger can be freely actuated in one rotational position, while the trigger is blocked in a rotational position offset by 90 °.
- This locking element is extremely difficult to operate. For rotation, a finger or other object must be inserted into the space between the trigger and the handle.
- the invention has for its object to provide a spray or spray gun of the generic type, which has a particularly simple way of accommodating the locking device.
- the trigger lever is gripped by a projection attached to the handle and the locking element is housed in this projection and that the locking element has an axially displaceable bolt by actuation from the outside, which extends approximately in the longitudinal direction of the handle.
- the accommodation of the locking element in the projection is a particularly simple way to accommodate essential parts of the locking device so that they can engage at the lower end of the trigger.
- the idle stroke required at the actuation point of the valve or the like is reduced compared to the idle stroke in the area of the locking element to a value reduced in the ratio of the lever arms.
- the effective working stroke is only slightly reduced, so that it is always possible to achieve the maximum material output.
- the bolt can engage directly or with an attached head in the movement path of the trigger. The surfaces guiding the bolt absorb the forces transmitted to the trigger in the locking position.
- the locking element is preferably loaded by a spring in the direction of the locking position. If no special measures are taken, the locking element returns to the locking position after the trigger is released.
- the projection can be designed as a removable handle insert. This makes assembly easier because the handle insert with its installation parts can be completed before the gun is assembled.
- the trigger lever carries at the lower end a rearward extension on which the locking element engages.
- the extension engages so far into the handle that it makes it easy to accommodate the locking element there.
- the locking element is displaceable by an actuating element near the upper end of the handle. There the locking element can be easily reached by the other hand. There is also the option of actuation by the thumb of the hand gripping the handle so that there is one-hand operation.
- the actuating element acts on an actuating rod axially displaceable in the handle on a pressure surface connected to the locking element. This results in a particularly simple construction.
- the locking element can be displaced by an actuating element near the lower end of the handle.
- This actuator can also be comfortably gripped by the other hand.
- the actuating element can, for example, be an axially movable button coupled to the locking element outside the handle. It is pulled out to release the trigger and remains in this position as long as the trigger is operated.
- the knob can also be rotatable and can be supported in at least one predetermined rotational angle position in an axial position corresponding to the release position of the locking element.
- the mode of operation just mentioned is then possible, but also a fixing of the locking element in the release position.
- the actuating element is a slide which can be moved transversely to the center plane of the pistol and which can be partially pushed out of the handle in both directions and has a control cam for engaging the locking element or a part coupled therewith. At the position Such an actuating element can be easily recognized whether the locking element is in the locking or in the release position. In addition, actuation with a finger of the hand holding the handle is also possible.
- control curve can be formed by two grooves of different depths which are connected to one another via two ramps of opposite inclination. Under the force of the spring acting on the locking element, the slide maintains its predetermined position.
- the actuating element is formed by the handle insert which can be displaced in the longitudinal direction of the gun against the force of a spring and which adjusts the locking element by means of a control cam.
- the trigger is released automatically when the handle is gripped by hand.
- control cam can be firmly connected to the displaceable handle insert and act on a cross pin connected to the locking element. This results in a simple structure.
- a rear gun body 1 has a handle 2, which can be gripped by one hand.
- a trigger lever 3 is rotatably held at its upper end in a bearing 4 on the rear part of the gun body 1.
- a support plate 6 connected to an actuating rod 5 rests under the influence of a spring 7 near the bearing 4 on the trigger lever 3.
- the actuating rod 5 for example, a material valve and / or an air valve can be actuated.
- a handle insert 8 is attached to the front of the lower part of the handle.
- a locking element 9 is guided in the form of a bolt, which is connected via a coupling rod 10 to a button-shaped actuating element 11 and is loaded by a spring 12.
- the locking element 9 engages in the path of movement at the bottom Provided end of the trigger, rearward extension 13, so that the trigger 3 can be moved at most by the small amount of angle required to insert the locking element 9 in the illustrated position.
- the actuating element 11 In order to be able to actuate the pistol, the actuating element 11 must be pulled into the dashed position. Then the trigger 3 can be pivoted into the working position shown in dashed lines, in which the actuated valve is fully open.
- the actuating element 111 is also rotatable. At its top, it is connected in one piece to a support element 14, which has a rectangular cross section, is supported in the illustrated position on the underside of the handle insert 108 and, after a rotation of 90 °, can engage in the transverse groove 15 under the force of the spring 12.
- the locking element 9 is therefore locked in the position of the actuating element 111 shown in FIG. 2 in the release position.
- the coupling rod 10 is connected to a pin 17 via a clamping device 16. This lies against the control curve 18 of a slide 19 which extends transversely to the center plane of the pistol and has a greater length than the width of the handle insert 208.
- the control curve 18 consists of two grooves 20 and 21 of different depths, which are connected to one another via two ramps 22 and 23 of different inclinations.
- the locking element 9 assumes the release position. If the pin 17 is in the groove 21, the locking element 9 assumes the locking position. In the release position, the right end 24 of the slide 19 protrudes laterally from the handle 208; in the locked position, the left end 25 of the slide 19 protrudes from the handle insert 208 on the opposite side. In both cases, pressure can be applied to the outer end of the slide in each case.
- the handle insert 308 can be moved against the force of a spring 26 from the fully extended position to the position shown in dashed lines.
- the handle insert has a guide element 27 which engages in a corresponding guide 28 of the handle 302.
- the coupling rod 10 is guided in the handle 302. It is firmly connected to a transverse pin 29 which engages in a control cam 30 formed in the handle insert 308.
- the locking element 9 is pulled down into the release position because of the shape of the control cam 30, so that the trigger lever 3 can be operated freely.
- all parts immediately return to the locked position.
- the locking element 409 is designed as the head of a bolt 410 which has a pressure surface 31.
- An actuating rod 32 acts on it, which can be axially adjusted by a slide 19, as illustrated in FIG. 4. This slide can be operated at least in one direction of actuation by the thumb of the hand holding the handle.
- the bottoms of the two grooves 20 and 21 of the slide 19 can be connected to one another by a ramp.
- the locking element would automatically return to the locking position when the trigger is released.
- the support device for the actuating element 111 in FIG. 2 can also be designed in such a way that run-up ramps are provided on the handle insert 106, onto which a narrow actuating element runs during the rotational movement.

Abstract
Description
Die Erfindung bezieht sich auf eine Spritz- oder Sprühpistole mit einem Griffstück, einem nahe seinem oberen Ende drehbar gelagerten und sich nur längs des oberen Teils des Griffstücks erstreckenden Abzugshebel zur Pistolenbetätigung und einem Verriegelungselement, das am unteren Ende des Abzugshebels angeordnet ist und aus einer Freigabestellung außerhalb der Bahn des unteren Endes des Abzugshebels in eine Verriegelungsstellung in dieser Bahn verlagerbar ist.The invention relates to a spray gun with a handle, a trigger arm rotatably mounted near its upper end and extending only along the upper part of the handle, and a locking element which is arranged at the lower end of the trigger lever and from a release position is displaceable outside the path of the lower end of the trigger in a locking position in this path.
Spritz- oder Sprühpistolen dienen dazu, pulverförmige Materialien oder flüssige Materialien, wie Farbe oder Lacke, auf einen zu beschichtenden Gegenstand aufzubringen. Durch Verlagerung des Abzugshebels mit Hilfe des Zeigefingers der das Griffstück umgreifenden Hand wird die Pistole betätigt. Je nach Aufbau der Pistole werden ein oder mehrere Materialventile, ein oder mehrere Luftventile, ein Schalter zur Hochspannungsversorgung einer elektrostatischen Zusatzeinrichtung u. dgl. betätigt. Aufgrund einer Richtlinie der Berufsgenossenschaft muß der Abzugshebel gegen unbeabsichtigtes Auslösen gesichert sein. Beim Vorhandensein eines solchen Verriegelungselements muß der Abzug zunächst einen Leerhub durchlaufen, ehe das angesteuerte Ventil o. dgl. betätigt werden darf. Der Leerhub berücksichtigt das Spiel im Bereich des Verriegelungselements und gewisse Fertigungs- und Materialtoleranzen. Ist der Leerhub zu klein, kann durch eine Labilität der Bauteile doch eine Ansteuerung erfolgen. Wird ein ausreichender Leerhub gewählt, kann der eigentliche Arbeitshub so stark verkürzt werden, daß nicht mehr die maximale Materialmenge ausgestoßen wird.Spray or spray guns are used to apply powdery materials or liquid materials, such as paint or varnish, to an object to be coated. The pistol is actuated by moving the trigger lever with the index finger of the hand gripping the handle. Depending on the structure of the gun, one or more material valves, one or more air valves, a switch for the high voltage supply of an electrostatic auxiliary device and the like. Like. operated. According to a directive of the trade association, the trigger must be secured against unintentional triggering. If such a locking element is present, the trigger must first go through an idle stroke before the actuated valve or the like may be actuated. The idle stroke takes into account the play in the area of the locking element and certain manufacturing and Material tolerances. If the idle stroke is too small, control can take place due to the instability of the components. If a sufficient idle stroke is selected, the actual working stroke can be shortened so much that the maximum amount of material is no longer ejected.
Eine gattungsgemäße Spritz- oder Sprühpistole ist aus DE-B2-2 102 252 bekannt. Bei ihr besteht das Verriegelungselement aus einem drehbaren Teil, das zwischen dem unteren Teil des Abzugshebels und dem oberen Teil des Griffstücks angeordnet ist. In der einen Drehstellung ist eine freie Betätigung des Abzugshebels möglich, in einer um 90° versetzten Drehstellung dagegen ist der Abzugshebel blockiert. Dieses Verriegelungselement ist außerordentlich schwierig zu betätigen. Zwecks Drehung muß ein Finger oder ein anderer Gegenstand in den Zwischenraum zwischen Abzugshebel und Griffstück eingeführt werden.A generic spray or spray gun is known from DE-B2-2 102 252. In her, the locking element consists of a rotatable part which is arranged between the lower part of the trigger and the upper part of the handle. The trigger can be freely actuated in one rotational position, while the trigger is blocked in a rotational position offset by 90 °. This locking element is extremely difficult to operate. For rotation, a finger or other object must be inserted into the space between the trigger and the handle.
Der Erfindung liegt die Aufgabe zugrunde, eine Spritzoder Sprühpistole der gattungsgemäßen Art anzugeben, die eine besonders einfache Möglichkeit der Unterbringung der Verriegelungsvorrichtung aufweist.The invention has for its object to provide a spray or spray gun of the generic type, which has a particularly simple way of accommodating the locking device.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Abzugshebel durch einen am Griffstück angebrachten Vorsprung untergriffen und das Verriegelungselement in diesem Vorsprung untergebracht ist und daß das Verriegelungslement einen durch Betätigung von außen axial verschiebbaren Bolzen aufweist, der sich etwa in Längsrichtung des Griffstücks erstreckt.This object is achieved in that the trigger lever is gripped by a projection attached to the handle and the locking element is housed in this projection and that the locking element has an axially displaceable bolt by actuation from the outside, which extends approximately in the longitudinal direction of the handle.
Die Unterbringung des Verriegelungselements im Vorsprung stellt eine besonders einfache Möglichkeit dar, wesentliche Teile der Verriegelungsvorrichtung so unterzubringen, daß sie am unteren Ende des Abzugshebels angreifen können. Durch den Angriff des Verriegelungselements am freien Ende des Abzugshebels reduziert sich der an der Betätigungsstelle des Ventils o. dgl. erforderliche Leerhub gegenüber dem Leerhub im Bereich des Verriegelungselements auf einen im Verhältnis der Hebelarme verkleinerten Wert. Infolgedessen ist der wirksame Arbeitshub nur wenig verkleinert, so daß es immer möglich ist, den maximalen Materialausstoß zu erreichen. Der Bolzen kann direkt oder mit einem angesetzten Kopf in die Bewegungsbahn des Abzugshebels greifen. Die den Bolzen führenden Flächen nehmen die in der Verriegelungsstellung auf den Abzugshebel übertragenden Kräfte auf.The accommodation of the locking element in the projection is a particularly simple way to accommodate essential parts of the locking device so that they can engage at the lower end of the trigger. By attacking the locking element at the free end of the trigger, the idle stroke required at the actuation point of the valve or the like is reduced compared to the idle stroke in the area of the locking element to a value reduced in the ratio of the lever arms. As a result, the effective working stroke is only slightly reduced, so that it is always possible to achieve the maximum material output. The bolt can engage directly or with an attached head in the movement path of the trigger. The surfaces guiding the bolt absorb the forces transmitted to the trigger in the locking position.
Vorzugsweise ist das Verriegelungselement durch eine Feder in Richtung der Verriegelungsstellung belastet. Wenn keine besonderen Maßnahmen getroffen sind, geht das Verriegelungselement jeweils nach Freigabe des Abzugshebels wieder in die Verriegelungsstellung zurück.The locking element is preferably loaded by a spring in the direction of the locking position. If no special measures are taken, the locking element returns to the locking position after the trigger is released.
Insbesondere kann der Vorsprung als abnehmbarer Griffeinsatz ausgebildet sein. Dies erleichtert die Montage, weil der Griffeinsatz mit seinen Einbauteilen bereits vor dem Zusammenbau der Pistole fertiggestellt werden kann.In particular, the projection can be designed as a removable handle insert. This makes assembly easier because the handle insert with its installation parts can be completed before the gun is assembled.
Günstig ist es auch, daß der Abzugshebel am unteren Ende einen nach hinten gerichteten Fortsatz trägt, an dem das Verriegelungselement angreift. Der Fortsatz greift so weit in das Griffstück hinein, daß es keine Schwierigkeiten macht, dort das Verriegelungselement unterzubringen.It is also favorable that the trigger lever carries at the lower end a rearward extension on which the locking element engages. The extension engages so far into the handle that it makes it easy to accommodate the locking element there.
Bei einer bevorzugten Ausführungsform ist das Verriegelungselement durch ein Betätigungselement nahe dem oberen Ende des Griffstücks verlagerbar. Dort kann das Verriegelungselement leicht durch die andere Hand erreicht werden. Darüber hinaus besteht die Möglichkeit der Betätigung durch den Daumen der das Griffstück umgreifenden Hand, so daß sich eine Ein-Hand-Bedienung ergibt.In a preferred embodiment, the locking element is displaceable by an actuating element near the upper end of the handle. There the locking element can be easily reached by the other hand. There is also the option of actuation by the thumb of the hand gripping the handle so that there is one-hand operation.
In diesem Fall empfiehlt es sich, daß das Betätigungselement über eine im Griffstück axial verlagerbare Betätigungsstange auf eine mit dem Verriegelungselement verbundene Druckfläche wirkt. Dies ergibt eine besonders einfache Konstruktion.In this case, it is recommended that the actuating element acts on an actuating rod axially displaceable in the handle on a pressure surface connected to the locking element. This results in a particularly simple construction.
Bei einer Alternative ist das Verriegelungselement durch ein Betätigungselement nahe dem unteren Ende des Griffstücks verlagerbar. Auch diese Betätigungselement kann bequem durch die andere Hand ergriffen werden. Darüber hinaus besteht die Möglichkeit der Betätigung durch den kleinen Finger der das Griffstück umfassenden Hand, so daß sich wiederum eine Ein-Hand-Bedienung ergibt.In an alternative, the locking element can be displaced by an actuating element near the lower end of the handle. This actuator can also be comfortably gripped by the other hand. In addition, there is the possibility of actuation by the little finger of the hand encompassing the handle, so that in turn one-hand operation results.
Das Betätigungselement kann beispielsweise ein mit dem Verriegelungselement gekuppelter, axial bewegbarer Knopf außerhalb des Griffstücks sein. Er wird zur Freigabe des Abzugshebels herausgezogen und bleibt in dieser Stellung, solange der Abzugshebel betätigt ist.The actuating element can, for example, be an axially movable button coupled to the locking element outside the handle. It is pulled out to release the trigger and remains in this position as long as the trigger is operated.
Der Knopf kann aber auch drehbar und in mindestens einer vorgegebenen Drehwinkellage in einer der Freigabestellung des Verriegelungselements entsprechenden Axiallage abstützbar sein. Es ist dann die soeben erwähnte Betriebsweise möglich, aber auch eine Festlegung des Verriegelungselements in der Freigabestellung.However, the knob can also be rotatable and can be supported in at least one predetermined rotational angle position in an axial position corresponding to the release position of the locking element. The mode of operation just mentioned is then possible, but also a fixing of the locking element in the release position.
Besonders gute Ergebnisse erzielt man dadurch, daß das Betätigungselement ein quer zur Pistolenmittelebene bewegbarer Schieber ist, der in beiden Richtungen teilweise aus dem Griffstück herausschiebbar ist und eine Steuerkurve zur Anlage des Verriegelungselements oder eines damit gekuppelten Teiles aufweist. An der Stellung eines solchen Betätigungselements läßt sich leicht erkennen, ob das Verriegelungselement in der Verriegelungs-oder in der Freigabestellung steht. Außerdem ist auch eine Betätigung mit einem Finger der den Griff haltenden Hand möglich.Particularly good results are achieved in that the actuating element is a slide which can be moved transversely to the center plane of the pistol and which can be partially pushed out of the handle in both directions and has a control cam for engaging the locking element or a part coupled therewith. At the position Such an actuating element can be easily recognized whether the locking element is in the locking or in the release position. In addition, actuation with a finger of the hand holding the handle is also possible.
Insbesondere kann die Steuerkurve durch zwei unterschiedlich tiefe Nuten gebildet sein, die über zwei Rampen entgegengesetzter Neigung miteinander verbunden sind. Unter der Kraft der auf das Verriegelungselement wirkenden Feder behält der Schieber seine jeweils vorgegebene Position bei.In particular, the control curve can be formed by two grooves of different depths which are connected to one another via two ramps of opposite inclination. Under the force of the spring acting on the locking element, the slide maintains its predetermined position.
Eine andere Möglichkeit besteht darin, daß das Betätigungselement durch den Griffeinsatz gebildet ist, der in Längsrichtung der Pistole gegen die Kraft einer Feder verlagerbar ist und mittels einer Steuerkurve das Verriegelungselement verstellt. Hier erfolgt eine automatische Freigabe des Abzugshebels, wenn das Griffstück mit der Hand erfaßt wird.Another possibility is that the actuating element is formed by the handle insert which can be displaced in the longitudinal direction of the gun against the force of a spring and which adjusts the locking element by means of a control cam. The trigger is released automatically when the handle is gripped by hand.
Insbesondere kann hierbei Steuerkurve mit dem verlagerbaren Griffeinsatz fest verbunden sein und auf einen mit dem Verriegelungselement verbundenen Querstift wirken. Dies ergibt einen einfachen Aufbau.In particular, the control cam can be firmly connected to the displaceable handle insert and act on a cross pin connected to the locking element. This results in a simple structure.

In Fig. 1 besitzt ein hinterer Pistolenkörper 1 ein Griffstück 2, das von einer Hand umfaßt werden kann. Ein Abzugshebel 3 ist an seinem oberen Ende in einem Lager 4 drehbar am hinteren Teil des Pistolenkörpers 1 gehalten. Ein mit einer Betätigungsstange 5 verbundener Stützteller 6 liegt unter dem Einfluß einer Feder 7 nahe dem Lager 4 am Abzugshebel 3 an. Mit der Betätigungsstange 5 kann beispielsweise ein Materialventil und/oder ein Luftventil betätigt werden. Wenn der Abzugshebel 3 aus seiner vollausgezogenen Stellung in die gestrichelt gezeichnete Stellung verschwenkt wird, öffnet sich die Ventilanordnung bis in ihre Endstellung.In Fig. 1, a
Am unteren Teil des Griffstücks ist vorn ein Griffeinsatz 8 angebracht. In diesem ist ein Verriegelungselement 9 in der Form eines Bolzens geführt, das über eine Kupplungsstange 10 mit einem knopfförmigen Betätigungselement 11 verbunden und durch eine Feder 12 belastet ist.A
In der veranschaulichten Stellung greift das Verriegelungselement 9 in die Bewegungsbahn eines am unteren Ende des Abzugshebels vorgesehen, nach hinten gerichteten Fortsatzes 13, so daß der Abzugshebel 3 höchstens um den kleinen Winkelbetrag bewegt werden kann, der zum Einschieben des Verriegelungselements 9 in die veranschaulichte Stellung erforderlich ist. Um die Pistole betätigen zu können, muß das Betätigungselement 11 in die gestrichelte Stellung gezogen werden. Dann kann der Abzugshebel 3 in die gestrichelt gezeichnete Arbeitsstellung verschwenkt werden, in der das betätigte Ventil voll geöffnet ist.In the illustrated position, the locking
Bei der Abwandlung nach Fig. 2 werden für identische Teile dieselben und für entsprechende Teile um 100 erhöhte Bezugszeichen verwendet. Hier ist das Betätigungselement 111 auch drehbar. An seiner Oberseite ist es einstückig mit einem Stützelement 14 verbunden, das rechteckigen Querschnitt hat, sich in der veranschaulichten Stellung auf der Unterseite des Griffeinsatzes 108 abstützt und nach einer Drehung um 90° unter der Kraft der Feder 12 in die Quernut 15 eingreifen kann. Das Verriegelungselement 9 ist daher in der in Fig. 2 dargestellten Lage des Betätigungselementes 111 in der Freigabestellung arretiert.In the modification according to FIG. 2, the same reference numerals are used for identical parts and reference numerals increased by 100 for corresponding parts. Here, the
Bei der Ausführungsform der Fig. 3 und 4, in der für entsprechende Teile um 200 erhöhte Bezugszeichen verwendet werden, ist die Kupplungsstange 10 über eine Klemmvorrichtung 16 mit einem Stift 17 verbunden. Dieser liegt an der Steuerkurve 18 eines Schiebers 19 an, welcher sich quer zur Pistolenmittelebene erstreckt und eine größere Länge als die Breite des Griffeinsatzes 208 hat. Die Steuerkurve 18 besteht aus zwei unterschiedlich tiefen Nuten 20 und 21, die über zwei Rampen 22 und 23 unterschiedlicher Neigung miteinander verbunden sind.In the embodiment of FIGS. 3 and 4, in which reference numerals increased by 200 for corresponding parts are used, the
Wenn sich der Stift 17 in der Nut 20 befindet, nimmt das Verriegelungselement 9 die Freigabestellung ein. Befindet sich der Stift 17 in der Nut 21, nimmt das Verriegelungselement 9 die Verriegelungsstellung ein. In der Freigabestellung ragt das rechte Ende 24 des Schiebers 19 seitlich aus dem Griffstück 208; in der Verriegelungsstellung ragt das linke Ende 25 des Schiebers 19 auf der gegenüberliegenden Seite aus dem Griffeinsatz 208. In beiden Fällen kann durch einen Druck auf das jeweils außen befindliche Ende des Schiebers ein Umschalten erfolgen.When the
Bei der Ausführungsform nach Fig. 5, bei der für entsprechende Teile um 300 erhöhte Bezugszeichen verwendet werden, sind nur bruchstückhafte Teile des Griffstücks 302 dargestellt. Der Griffeinsatz 308 ist gegen die Kraft einer Feder 26 aus der vollausgezogenen Stellung in die gestrichelt gezeichnete Stellung verlagerbar. Hierbei besitzt der Griffeinsatz ein Führungselement 27, das in eine entsprechende Führung 28 des Griffstücks 302 eingreift. Die Kupplungsstange 10 ist im Griffstück 302 geführt. Sie ist mit einem Querstift 29 fest verbunden, der in eine im Griffeinsatz 308 ausgebildeten Steuerkurve 30 greift. Wird die Pistole aufgenommen, drücken die dritten bis fünften Finger der Hand den Griffeinsatz 308 nach hinten. Hierdurch wird das Verriegelungselement 9 wegen der Form der Steuerkurve 30 nach unten in die Freigabestellung gezogen, so daß der Abzugshebel 3 frei betätigt werden kann. Beim Loslassen des Griffstücks kehren alle Teile sofort in die Verriegelungsstellung zurück.In the embodiment according to FIG. 5, in which reference numerals increased by 300 for corresponding parts, only fragmentary parts of the
Bei der Ausführungsform nach Fig. 6, bei der für entsprechende Teile um 400 erhöhte Bezugszeichen verwendet werden, ist das Verriegelungselement 409 als Kopf eines Bolzens 410 ausgebildet, der eine Druckfläche 31 aufweist. Auf sie wirkt eine Betätigungsstange 32, die durch einen Schieber 19, wie er in Fig. 4 veranschaulicht ist, axial verstellt werden kann. Dieser Schieber kann zumindest in der einen Betätigungsrichtung durch den Daumen der das Griffstück haltenden Hand betätigt werden.In the embodiment according to FIG. 6, in which reference numerals increased by 400 for corresponding parts are used, the locking
Von den dargestellten Ausführungsformen kann in vielerlei Hinsicht abgewichen werden, ohne den Grundgedanken der Neuerung zu verlassen. Beispielsweise können die Böden der beiden Nuten 20 und 21 des Schiebers 19 durch eine Rampe miteinander verbunden werden. In diesem Fall würde das Verriegelungselement selbsttätig in die Verriegelungsstellung zurückkehren, wenn der Abzugshebel freigegeben wird. Die Stützvorrichtung für das Betätigungselement 111 in Fig. 2 kann auch so ausgeführt werden, daß auf dem Griffeinsatz 106 Auflauframpen vorgesehen sind, auf die ein schmales Betätigungselement bei der Drehbewegung aufläuft.There can be deviations from the illustrated embodiments in many respects without leaving the basic idea of the innovation.
