Die folgende Erfindung betrifft einen Geradezugverschluss für Repetiergewehre gemäß dem beigefügten Anspruch 1. Außerdem betrifft die Erfindung ein Repetiergewehr mit einem solchen Geradezugverschluss.The following invention relates to a straight pull breech for bolt-action rifles according to the attached claim 1. The invention also relates to a bolt-action rifle with such a straight pull bolt.

Von der Firma Merkel Jagd- und Sportwaffen GmbH ist ein unter der Bezeichnung "Helix" vertriebener Geradezug-Repetierer bekannt, bei welchem ein klassischer Drehkopfverschluss mit einem Übersetzungsgetriebe kombiniert wird. Bei dem Helix-Verschlussprinzip bewegen sich Verschlusswarzen entlang einer gedachten mehrspindeligen Helix.A straight pull repeater sold under the name "Helix" is known from the company Merkel Jagd- und Sportwaffen GmbH, in which a classic rotary head lock is combined with a transmission gear. With the helix locking principle, locking lugs move along an imaginary multi-spindle helix.

Die EP 0 784 194 B1 zeigt einen Geradezugverschluss für eine Repetierbüchse mit einem in Laufrichtung in einer Kammerhülse verschiebbaren und um seine Achse drehbaren Verschlusskopf. Im Verschlusskopf ist ein Schlagbolzen axial verschiebbar. Ein Kammergriff ist innerhalb einer in der Kammerhülse verschiebbaren Steuerhülse quer zur Waffenachse über einen Haltebolzen schwenkbeweglich gelagert. Innerhalb der Steuerhülse ist ein Zwischenstück axial verschiebbar gelagert, welches den Haltebolzen umgreift und auf der vorderen Seite mit dem Schlagbolzen und auf der hinteren Seite mit einem eine Schlagfeder spannenden Schlagstück in Wirkverbindung steht. Der Verschlusskopf enthält Steuerbolzen, die in Steuerkurven der Steuerhülse eingreifen und jeweilige Rotationsbewegungen zur Ver- und Entriegelung des Verschlusskopfes gegenüber dem Schlagstück während der Betätigung des Kammergriffs durchführen.The EP 0 784 194 B1 shows a straight pull lock for a bolt action rifle with a lock head that can be displaced in the direction of travel in a chamber sleeve and rotated about its axis. A firing pin is axially displaceable in the bolt head. A bolt handle is mounted within a control sleeve, which can be displaced in the chamber sleeve, such that it can pivot transversely to the weapon axis via a retaining bolt. An intermediate piece is mounted axially displaceably within the control sleeve and engages around the retaining bolt and is in operative connection on the front side with the firing pin and on the rear side with a striking piece tensioning a striker spring. The bolt head contains control bolts which engage in control cams of the control sleeve and perform respective rotational movements for locking and unlocking the bolt head with respect to the hammer while the bolt handle is actuated.

Die DE 10 2016 120 891 A1 beinhaltet eine Verschlusseinrichtung für Repetiergewehre umfassend ein Patronenlager, eine außenliegende Hülse und eine in dieser aufgenommenen Kammer. Die Kammer weist in dem dem Patronenlager zugewandten Bereich einen Verschlusskopf auf. Innerhalb der Kammer ist ein Steuerstück gegenüber der Kammer und gegenüber dem Verschlusskopf axial verschieblich gelagert. Mit dem Steuerstück ist ein Kammerhebel derart verbunden, dass bei einer Rückwärtsbewegung des Kammerhebels der Verschlusskopf entriegelt und beim Vorlauf verriegelt wird. Der Kammerhebel ist im hinteren Endbereich der Hülse schwenkbar um eine außermittig zur Längsachse der Kammer verlaufende Achse angebracht. Das Steuerstück ist über ein Zwischenstück mit dem Kammerhebel verbunden, welches von der Kammer aus radial nach außen hin ragt. Der Verschlusskopf ist um seine Achse drehbar in der Kammer gelagert. Er kann durch axiales Verschieben des Steuerstücks gedreht werden.The DE 10 2016 120 891 A1 includes a locking device for repeating rifles comprising a cartridge chamber, an external case and a chamber accommodated in this. The chamber has a locking head in the area facing the cartridge chamber. Within the chamber, a control piece is mounted so as to be axially displaceable relative to the chamber and relative to the locking head. A chamber lever is connected to the control piece in such a way that the bolt head is unlocked when the chamber lever is moved backwards and locked when it moves forward. The chamber lever is mounted in the rear end region of the sleeve so as to be pivotable about an axis extending eccentrically to the longitudinal axis of the chamber. The control piece is connected to the chamber lever via an intermediate piece, which protrudes radially outward from the chamber. The locking head is mounted in the chamber so that it can rotate about its axis. It can be rotated by moving the control piece axially.

In der DE 100 09 616 C2 ist ein Geradezugverschluss für Repetiergewehre beschrieben. Der Verschluss umfasst eine in einem Verschlussgehäuse geführte und einen Kammerstengel für das händische Hin- und Herbewegen tragende Verschlusshülse. In der Verschlusshülse ist ein mittels eines Schaftes zwangsgeführter Verschlusskopf drehbeweglich gelagert, welcher Verriegelungswarzen aufweist. Ein Schlagbolzen ist von einer Schlagbolzenfeder beaufschlagt, welche der Erzeugung eines Drehimpulses dient, um den Verschlusskopf in der Verschlussstellung in die mit den Verriegelungswarzen korrespondierende Verriegelungskammer einzudrehen. Ein von einer Feder in Arretierrichtung beaufschlagter, an der Verschlusshülse kippbeweglich gelagerter Arretierhebel verhindert Relativbewegungen zwischen der Verschlusshülse und dem Verschlusskopf. Ein erster Hebelarm des Arretierhebels weist einen mit einer Rastnut im Schaft des Verschlusskopfes korrespondierenden Rastvorsprung auf, während ein zweiter Hebelarm des Arretierhebels eine mit einer Schaltkante einer Verschlussbrücke zusammenwirkende Steuerrampe besitzt. Beim Bewegen von Verschlusshülse und Verschlusskopf in die Verschlussstellung wird der Arretierhebel mit Erreichen der Verschlussstellung über die Steuerrampe entgegen der Wirkung der Feder außer Eingriff mit der Rastnut gebracht. Beim Bewegen aus der Verschlussstellung heraus rastet der Arretierhebel mit seinem Rastvorsprung federnd wieder ein.In the DE 100 09 616 C2 describes a straight pull bolt for bolt action rifles. The lock comprises a lock sleeve which is guided in a lock housing and carries a bolt handle for manual movement back and forth. A locking head, which is positively guided by means of a shaft and which has locking lugs, is mounted so as to be rotatable in the locking sleeve. A firing pin is acted upon by a firing pin spring, which is used to generate an angular momentum in order to screw the locking head in the locking position into the locking chamber corresponding to the locking lugs. A locking lever, which is acted upon by a spring in the locking direction and is tiltably mounted on the locking sleeve, prevents relative movements between the locking sleeve and the locking head. A first lever arm of the locking lever has a locking groove in the shaft of the Locking head corresponding locking projection, while a second lever arm of the locking lever has a control ramp cooperating with a switching edge of a locking bridge. When the locking sleeve and locking head are moved into the locking position, the locking lever is disengaged from the locking groove against the action of the spring when the locking position is reached via the control ramp. When moving out of the closed position, the locking lever with its locking projection engages resiliently again.

Die US 2017/0016688 A1 beschreibt eine Repetieranordnung, welche einen Hauptkörper besitzt, der entlang einer Mittelachse zentrale Bohrungen und zwei Schlitze besitzt, wobei das Schlitzpaar gegenüberliegend angeordnet ist. Die Schlitze ziehen sich entlang der Mittelachse des gesamten Hauptkörpers. An dem Hauptkörper ist ein Nockenzylinder angebracht, welcher spiralförmige Schlitze enthält, die spiegelsymmetrisch zur Mittelachse verlaufen. Innerhalb des Nockenzylinders ist ein Nockenstift angeordnet, welcher senkrecht zur Mittelachse durch die spiralförmigen Schlitze des Nockenzylinders und die länglichen Schlitze des Hauptkörpers verläuft. Weiterhin ist an dem Nockenzylinder ein Griff gekoppelt, durch dessen Drehung sich der Nockenzylinder mitdreht, sodass sich die spiralförmigen Schlitze des Nockenzylinders um den Nockenstift winden und eine Axialkraft ausüben. Dies bewirkt eine Verschiebung des Nockenstifts in die länglichen Schlitze des Hauptkörpers.The US 2017/0016688 A1 describes a repeater assembly having a main body having central bores and two slots along a central axis, the pair of slots being arranged opposite one another. The slots run along the central axis of the entire main body. A cam cylinder is attached to the main body and contains spiral slots that are mirror-symmetrical to the central axis. A cam pin is disposed within the cam cylinder and extends perpendicular to the central axis through the spiral slots of the cam cylinder and the elongated slots of the main body. Furthermore, a handle is coupled to the cam cylinder, through the rotation of which the cam cylinder rotates with it, so that the spiral-shaped slots of the cam cylinder wind around the cam pin and exert an axial force. This causes the cam pin to slide into the elongated slots in the main body.

Die Aufgabe der vorliegenden Erfindung besteht ausgehend vom Stand der Technik darin, einen alternativen Geradezugverschluss für Repetiergewehre zur Verfügung zu stellen, welcher einfach und schnell zu betätigen ist sowie eine hohe Betriebssicherheit auch unter ungünstigen Bedingungen, beispielsweise bei deformierten oder nicht maßhaltigen Patronen aufweist.The object of the present invention, based on the state of the art, is to provide an alternative straight pull lock for repeating rifles which can be operated easily and quickly as well as a high level of operational reliability even under unfavorable conditions, for example with deformed or non-dimensionally stable cartridges.

Zur Lösung dieser Aufgabe dient ein Geradezugverschluss für Repetiergewehre gemäß dem beigefügten Anspruch 1.A straight pull lock for repeating rifles according to the appended claim 1 serves to solve this problem.

Der erfindungsgemäße Geradezugverschluss weist eine Längsachse auf. Eine Verschlusshülse ist um die Längsachse drehbar gelagert. Die Verschlusshülse besitzt ein vorderes Ende, an welchem ein Verschlusskopf angeordnet ist, und ein hinteres Ende. In den Innenmantel der Verschlusshülse ist im Bereich des hinteren Endes eine sich schräg zur Längsachse erstreckende Steuerkurve eingebracht. Der Geradezugverschluss umfasst weiterhin ein sich in Richtung der Längsachse erstreckendes Verbindungsglied mit einem vorderen Ende, an welchem ein mit der Steuerkurve der Verschlusshülse in Eingriff stehender Zapfen angeordnet ist, und mit einem hinteren Ende, wobei im Bereich des hinteren Endes eine Ausnehmung eingebracht ist. Ein weiterer Bestandteil des Geradezugverschlusses ist ein Steuerelement, welches eine Wellenform mit Auswölbungen aufweist. Das Steuerelement ist mit einer in die Ausnehmung des Verbindungsgliedes eingreifenden Steuernocke, einer Durchgangsöffnung zum Durchführen eines Schlagbolzens und mit einer sich quer zur Längsachse erstreckenden Welle ausgestattet. Mit der Welle dem Steuerelement ist ein Kammergriff drehfest verbunden. Mittels Kammergriff kann das Steuerelement zwischen einer Öffnungsposition und einer Schließposition verschwenkt werden. In der Öffnungsposition ist der Verschlusskopf verriegelt, während in der Schließposition der Verschlusskopf entriegelt ist.The straight pull fastener according to the invention has a longitudinal axis. A closure sleeve is rotatably mounted about the longitudinal axis. The locking sleeve has a front end, on which a locking head is arranged, and a rear end. A control cam extending obliquely to the longitudinal axis is introduced into the inner jacket of the closure sleeve in the region of the rear end. The straight pull lock further comprises a connecting member extending in the direction of the longitudinal axis with a front end on which a pin engaging the cam of the lock sleeve is arranged, and with a rear end, a recess being made in the area of the rear end. Another component of the straight pull lock is a control element which has a wave shape with bulges. The control element is equipped with a control cam engaging in the recess of the connecting link, a through opening for the passage of a firing pin and with a shaft extending transversely to the longitudinal axis. A bolt handle is rotatably connected to the shaft of the control element. The control element can be pivoted between an open position and a closed position by means of a bolt handle. In the open position the bolt head is locked, while in the closed position the bolt head is unlocked.

Nachfolgend wird die Funktionsweise des erfindungsgemäßen Geradezugverschlusses näher erläutert. Beim Schwenken des Kammergriffs nach hinten, d. h. von dem Verschlusskopf weg, wird das mit dem Kammergriff drehfest verbundene Steuerelement gedreht. Der an das Steuerelement angebrachte, in die Ausnehmung des Verbindungsgliedes eingreifende Steuernocken zieht das Verbindungsglied nach hinten. Der am vorderen Ende des Verbindungsgliedes befindliche Zapfen wird entlang der Steuerkurve in der Verschlusshülse geführt und versetzt hierdurch die Verschlusshülse und somit auch den Verschlusskopf in eine Rotationsbewegung. Der Verschluss befindet sich nunmehr im Öffnungszustand und ist verriegelt. Zum Überführen des Verschlusses in den Schließzustand erfolgt ein Verschwenken des Kammergriffes nach vorne, d. h. in Richtung des Verschlusskopfes. Die Steuernocke drückt das Verbindungsglied nach vorne. Der Zapfen verdreht die Verschlusshülse in umgekehrter Drehrichtung. Der Verschluss ist nun im Schließzustand, in welchem er entriegelt ist.The mode of operation of the straight pull lock according to the invention is explained in more detail below. When panning the Bolt handle backwards, ie away from the bolt head, the control element connected to the bolt handle in a rotationally fixed manner is rotated. The control cam attached to the control element and engaging in the recess of the connecting link pulls the connecting link backwards. The pin located at the front end of the connecting link is guided along the control curve in the locking sleeve and thereby sets the locking sleeve and thus also the locking head in a rotational movement. The lock is now in the open state and locked. To bring the lock into the locked state, the bolt handle is pivoted forwards, ie in the direction of the lock head. The control cam pushes the connecting link forward. The pin rotates the locking sleeve in the opposite direction of rotation. The lock is now in the closed state in which it is unlocked.

Erfindungsgemäß wird eine Drehung der Verschlusshülse durch Umsetzung der Kippbewegung am Kammergriff ermöglicht. Hierfür sind keine Änderungen am Lauf des Repetiergewehres erforderlich. Weiterhin ist vorteilhaft, dass der Auswerfer aufgrund der erfindungsgemäß realisierten, verhältnismäßig großen Übersetzung mit großer Kraft arbeitet, wodurch auch verkantete Patronen aus der Gewehrhülse problemlos herausgeworfen werden können. Der erfindungsgemäße Geradezugverschluss ist aufwandsarm zu realisieren.According to the invention, a rotation of the locking sleeve is made possible by implementing the tilting movement on the bolt handle. No changes to the barrel of the repeating rifle are required for this. Furthermore, it is advantageous that the ejector works with great force due to the relatively large translation implemented according to the invention, so that even canted cartridges can be ejected from the rifle case without any problems. The straight pull fastener according to the invention can be implemented with little effort.

Mit dem Geradezugverschluss lässt sich vorzugsweise ein Verdrehen der Verschlusshülse um einen Drehwinkel von 60° realisieren. Dieser vergleichsweise große Drehwinkel ermöglicht eine sichere Verriegelung von Verschlusshülse und Verschlusskopf.With the straight pull lock, the locking sleeve can preferably be rotated by an angle of rotation of 60 °. This comparatively large angle of rotation enables the locking sleeve and locking head to be locked securely.

Während des Öffnungsvorgangs wird gleichzeitig vorzugsweise auch der Schlagbolzen gespannt.During the opening process, the firing pin is preferably also cocked at the same time.

Gemäß einer vorteilhaften Ausführungsform umfasst der Geradezugverschluss weiterhin eine Griffsperre, die zwischen einer Aktivierungsposition und einer Deaktivierungsposition verlagerbar ist. In der Deaktivierungsposition greift die Griffsperre an dem Steuerelement ein, um dieses im Öffnungszustand zu blockieren und einen Übergang in die Schließposition zu verhindern. In der Aktivierungsposition besteht kein blockierender Eingriff an dem Steuerelement, sodass das Steuerelement mittels des Kammergriffs von der Öffnungsposition in die Schließposition verschwenkt werden kann. In das Steuerelement ist vorzugsweise eine Ausnehmung zum Eingriff der Griffsperre eingebracht.According to an advantageous embodiment, the straight pull lock further comprises a grip lock that can be displaced between an activation position and a deactivation position. In the deactivation position, the handle lock engages the control element in order to block it in the open state and to prevent a transition into the closed position. In the activation position there is no blocking engagement with the control element, so that the control element can be pivoted from the open position into the closed position by means of the bolt handle. A recess for engaging the handle lock is preferably made in the control element.

Als vorteilhaft hat sich die Ausstattung des Steuerelements mit einem Anschlag zum Blockieren der Verschlusshülse in der Öffnungsposition erwiesen.It has proven advantageous to equip the control element with a stop for blocking the closure sleeve in the open position.

An der Welle des Steuerelements befindet sich vorzugsweise eine Rückholfeder für das Steuerelement, welche das selbsttätige Rückführen des Steuerelements ermöglicht.On the shaft of the control element there is preferably a return spring for the control element, which enables the control element to be automatically returned.

Das Verbindungsglied ist bevorzugt als Schlitten mit einer rechteckförmigen Grundfläche ausgebildet.The connecting member is preferably designed as a slide with a rectangular base area.

Eine vorteilhafte Ausführungsform nutzt ein Verschlussgehäuse. Innerhalb des Verschlussgehäuses sind zumindest das Steuerelement und das Verbindungsglied angeordnet. Durch das Verschlussgehäuse werden Steuerelement und Verbindungsglied vor Verschmutzungen und Beschädigungen geschützt. Am Verschlussgehäuse ist vorzugsweise ein Aktivierungshebel zum Aktivieren und Deaktivieren der Griffsperre angeordnet.An advantageous embodiment uses a lock housing. At least the control element and the connecting member are arranged within the closure housing. The lock housing protects the control element and connecting link from dirt and damage. At the Lock housing is preferably arranged an activation lever for activating and deactivating the handle lock.

Die Figuren 1 bis 3 zeigen verschiedene Ansichten eines erfindungsgemäßen Geradezugverschlusses 01 im verriegelten Zustand. Der Geradezugverschluss 01 besitzt eine Längsachse 02. Um die Längsachse 02 ist eine Verschlusshülse 03 drehbar gelagert. Die Verschlusshülse 03 weist ein vorderes Ende und ein hinteres Ende auf. An dem vorderen Ende der Verschlusshülse 03 ist ein Verschlusskopf 04 angeordnet. In den Innenmantel der Verschlusshülse 03 ist im Bereich des hinteren Endes eine sich schräg zu der Längsachse 02 bzw. schraubenlinienförmig erstreckende Steuerkurve 05 (siehe Fig. 3) eingebracht.The Figures 1 to 3 show different views of a straight pull lock 01 according to the invention in the locked state. The straight pull fastener 01 has a longitudinal axis 02. A sealing sleeve 03 is rotatably mounted about the longitudinal axis 02. The closure sleeve 03 has a front end and a rear end. A locking head 04 is arranged at the front end of the locking sleeve 03. In the inner jacket of the closure sleeve 03, in the area of the rear end, there is a control cam 05 extending obliquely to the longitudinal axis 02 or in a helical manner (see Fig. 3 ) brought in.

Der Geradezugverschluss 01 beinhaltet weiterhin ein Verbindungsglied 07, welches sich in Richtung der Längsachse 02 erstreckt. Das Verbindungsglied 07 weist ein vorderes Ende und ein hinteres Ende auf. An dem vorderen Ende ist ein mit der Steuerkurve 05 der Verschlusshülse 03 in Eingriff stehender Zapfen 08 angeordnet. Im Bereich des hinteren Endes des Verbindungsgliedes 07 ist eine Ausnehmung 09 eingebracht. Das Verbindungsglied 07 ist in der gezeigten Ausführung als Schlitten mit einer rechteckförmigen Grundfläche ausgebildet.The straight pull fastener 01 also includes a connecting member 07 which extends in the direction of the longitudinal axis 02. The connecting link 07 has a front end and a rear end. At the front end there is arranged a pin 08 which is in engagement with the control cam 05 of the closure sleeve 03. A recess 09 is made in the area of the rear end of the connecting link 07. In the embodiment shown, the connecting member 07 is designed as a slide with a rectangular base area.

Ein weiterer Bestandteil des Geradezugverschlusses ist ein Steuerelement 10, welche im Detail in Fig. 7 dargestellt ist. Das Steuerelement 10 umfasst eine Steuernocke 12, welche in die Ausnehmung 09 des Verbindungsgliedes 07 eingreift. In das Steuerelement 10 ist eine Durchgangsöffnung 13 zum Durchführen eines Schlagbolzens 14 eingebracht. Weiterhin besitzt das Steuerelement 10 eine Welle 15, welche sich quer zur Längsachse 02 erstreckt.Another component of the straight pull lock is a control element 10, which is shown in detail in Fig. 7 is shown. The control element 10 comprises a control cam 12 which engages in the recess 09 of the connecting member 07. A through opening 13 for leading a firing pin 14 through is made in the control element 10. The control element 10 also has a shaft 15 which extends transversely to the longitudinal axis 02.

Ein Kammergriff 17 ist mit der Welle 15 des Steuerelements 10 drehfest verbunden. Zum Durchführen mechanischer Befestigungsmittel für die Fixierung des Kammergriffes 17 ist in die Welle 15 des Steuerelements 10 eine Durchgangsbohrung 18 eingebracht. Der Kammergriff 17 ermöglicht ein Verschwenken des Steuerelements 10 zwischen einer Öffnungsposition und einer Schließposition.A bolt handle 17 is non-rotatably connected to the shaft 15 of the control element 10. To pass through mechanical fasteners for fixing the bolt handle 17 is in the shaft 15 of the control element 10 a through hole 18 is introduced. The bolt handle 17 enables the control element 10 to be pivoted between an open position and a closed position.

In der Öffnungsposition ist der Verschlusskopf 04 verriegelt, während er in der Schließposition entriegelt ist. In den Figuren 1 bis 3 ist der verriegelte Zustand dargestellt. Zum Überführen des Geradezugverschlusses 01 in den verriegelten Zustand wurde zuvor der Kammergriff 17 nach hinten, d. h. von dem Verschlusskopf 04 weg geschwenkt. Das mit dem Kammergriff 17 drehfest verbundene Steuerelement 10 wurde hierdurch gedreht. Der in die Ausnehmung 09 des Verbindungsgliedes 07 eingreifende Steuernocken 12 des Steuerelements 10 zog hierbei das Verbindungsglied 07 nach hinten. Der Zapfen 08 des Verbindungsgliedes 07 wurde infolgedessen entlang der Steuerkurve 05 der Verschlusshülse 03 geführt und versetzte hierdurch die Verschlusshülse 03 und den Verschlusskopf 04 in eine Rotationsbewegung. Während des Öffnungsvorgangs findet gleichzeitig auch ein Spannen des Schlagbolzens 14 statt.The locking head 04 is locked in the open position, while it is unlocked in the closed position. In the Figures 1 to 3 the locked state is shown. To transfer the straight-pull lock 01 into the locked state, the bolt handle 17 was previously pivoted backwards, ie away from the lock head 04. The control element 10, which is connected non-rotatably to the bolt handle 17, was thereby rotated. The control cam 12 of the control element 10 engaging in the recess 09 of the connecting member 07 pulled the connecting member 07 to the rear. The pin 08 of the connecting link 07 was consequently guided along the control curve 05 of the locking sleeve 03 and thereby set the locking sleeve 03 and the locking head 04 in a rotational movement. During the opening process, the firing pin 14 is also tensioned at the same time.

Beim Schließen des Geradezugverschlusses 01 erfolgt dieser Vorgang in umgekehrter Richtung. Der Kammergriff 17 wird demzufolge nach vorne, d. h. in Richtung des Verschlusskopfes 04 verschwenkt. Die Steuernocke 12 drückt das Verbindungsglied 07 nach vorne. Der Zapfen 08 verdreht die Verschlusshülse 03 und den Verschlusskopf 04 in umgekehrter Drehrichtung. Die Figuren 4 bis 6 zeigen den Geradezugverschluss 01 in seinem entriegelten Zustand, in welchem der Geradezugverschluss 01 geschlossen ist.When closing the straight-pull lock 01, this process takes place in the opposite direction. The bolt handle 17 is accordingly pivoted forwards, ie in the direction of the locking head 04. The control cam 12 pushes the connecting member 07 forwards. The pin 08 rotates the locking sleeve 03 and the locking head 04 in the opposite direction of rotation. The Figures 4 to 6 show the straight pull lock 01 in its unlocked state in which the straight pull lock 01 is closed.

An der Welle 15 des Steuerelements 10 ist eine Rückholfeder 19 für das Steuerelement 10 angeordnet. Die Verschlusshülse 03 weist an ihrer Außenseite eine manuell aktivierbare Sicherungseinrichtung 20 (siehe Fig. 4) zum Blockieren des Verschlusskopfes 04 in der Öffnungsposition auf.A return spring 19 for the control element 10 is arranged on the shaft 15 of the control element 10. The locking sleeve 03 has a manually activated safety device 20 on its outside (see Fig. 4 ) to block the bolt head 04 in the opening position.

Fig. 7 kann weiterhin entnommen werden, dass in das Steuerelement 10 eine Ausnehmung 22 eingebracht ist. Diese Ausnehmung 22 dient zum Eingriff einer Griffsperre (nicht dargestellt). Die Griffsperre kann zwischen einer Aktivierungsposition und einer Deaktivierungsposition verlagert werden. In der Deaktivierungsposition greift die Griffsperre in das Steuerelement 10 ein, um dieses im Öffnungszustand zu blockieren und einen Übergang in die Schließposition zu verhindern. In der Aktivierungsposition besteht kein blockierender Eingriff an dem Steuerelement 10, sodass das Steuerelement 10 mittels des Kammergriffs 17 von der Öffnungsposition in die Schließposition verschwenkt werden kann. Das Steuerelement 10 ist weiterhin mit einem Anschlag 23 zum Blockieren der Verschlusshülse 03 in der Öffnungsposition ausgestattet. Fig. 7 it can also be seen that a recess 22 is made in the control element 10. This recess 22 is used to engage a handle lock (not shown). The handle lock can be shifted between an activation position and a deactivation position. In the deactivation position, the handle lock engages in the control element 10 in order to block it in the open state and to prevent a transition into the closed position. In the activation position there is no blocking engagement on the control element 10, so that the control element 10 can be pivoted from the open position into the closed position by means of the bolt handle 17. The control element 10 is also equipped with a stop 23 for blocking the closure sleeve 03 in the open position.
