Die Handhabe kann z.B. einen Teil des Gehäuses bilden. Das Betätigungselement kann z.B. an der Handhabe gelagert sein.The actuating element is mounted for example on the housing. It may be mounted directly or indirectly in the housing. The actuating element may be mounted, for example, on the handle. With the handle, the actuator can be actuated, for example, directly or indirectly. The handle and the actuator can eg be formed of separate parts. Alternatively, for example, the handle and the actuating element may be formed by a component. The handle can form, for example, a region of the actuating element. The handle can, for example, form part of the housing. The actuating element may be mounted, for example, on the handle.

Die Betätigungsvorrichtung bildet im Sinne der Erfindung mit dem Klingenhalter ein Schwenkgelenk. Z.B. kann das Betätigungselement mittels eines Schenkgelenks mit dem Klingenhalter verbunden sein. Das Betätigungselement kann z.B. fest mit dem Klingenhalter verbunden sein. Alternativ kann das Betätigungselement z.B. lösbar mit dem Klingenhalter verbindbar sein. Im verbundenen Zustand sind Klingenhalter und Betätigungselement dann relativ zueinander schwenkbar.The actuator forms in the context of the invention with the blade holder a pivot joint. For example, For example, the actuating element can be connected to the blade holder by means of a pivot joint. The actuator may e.g. firmly connected to the blade holder. Alternatively, the actuator may be e.g. releasably connectable to the blade holder. In the connected state, blade holder and actuating element are then pivotable relative to each other.

Der Klingenhalter ist translatorisch beweglich und / oder drehbeweglich an dem Gehäuse gelagert. "Translatorisch beweglich" im Sinne der Erfindung bedeutet, dass der Klingenhalter entlang einer Bahn bewegbar ist. Die Bahn kann z.B. grade sein oder gekrümmt sein oder gerade und gekrümmte Teilbereiche aufweisen.The blade holder is translationally movable and / or rotatably mounted on the housing. "Translationally movable" in the sense of the invention means that the blade holder is movable along a path. The web can e.g. be straight or curved or have straight and curved portions.

Der Vorteil der Erfindung besteht darin, dass das Messer lediglich wenige Teile umfasst und eine einfache Konstruktion möglich ist. Das Messer ist auf diese Weise leicht herstellbar ist und verursacht geringe Herstellungskosten. Darüber hinaus weist das erfindungsgemäße Messer eine hohe Funktionssicherheit auf.The advantage of the invention is that the knife comprises only a few parts and a simple construction is possible. The knife is easy to produce in this way and causes low production costs. In addition, the knife according to the invention has a high reliability.

Insbesondere die Messerbestandteile Messergehäuse, Handhabe, Betätigungsvorrichtung, Klingenhalter mit Klinge und ggf. Stützelement können Elemente eines Getriebes bilden. Auf diese Weise ist es möglich, durch die Gestaltung der Getriebeelemente eine bestimmte Bewegungscharakteristik des Klingenhalters bei der Bewegung zwischen der Sicherheitsposition und der wenigstens einen Schneidposition zu erhalten. Die Betätigungsvorrichtung kann z.B. mit der Handhabe und dem Klingenhalter ein Viergelenk bilden. Die Betätigungsvorrichtung kann z.B. zwei Lenker umfassen die zum Einen an der Handhabe und zum anderen an dem Klingenhalter gelenkig gelagert sind.In particular, the knife components knife housing, handle, actuator, blade holder with blade and possibly support element can form elements of a transmission. In this way, it is possible by the design of the transmission elements, a certain movement characteristic of the blade holder in the movement between the safety position and the at least one cutting position. The actuator can eg form a four-bar linkage with the handle and the blade holder. The actuator may, for example, comprise two handlebars which are articulated on the one hand and on the other hand on the blade holder.

Indem der Klingenhalter z.B. bei der Bewegung von der zweiten Schneidposition in die Sicherheitsposition eine Schwenkbewegung in Richtung des Schneidmaterials durchführt, steigt die beim Schneiden entstehende Reibkraft zwischen Klinge und Schneidmaterial an. Auf diese Weise ist es z.B. möglich sehr dünne Materialien, wie z.B. Folie zu schneiden.By having the blade holder e.g. during the movement from the second cutting position to the safety position performs a pivoting movement in the direction of the cutting material, the resulting frictional force between blade and cutting material increases during cutting. In this way it is e.g. possible very thin materials, e.g. To cut foil.

Darüber hinaus kann über die Gestaltung der Getriebeelemente z.B. die Ausfahrbewegung des Klingeträgers beim Betätigen der Handhabe festgelegt werden.Moreover, the design of the transmission elements may include e.g. the extension movement of the blade carrier when operating the handle are determined.

Aufgrund der Lagerung des Klingenhalters, welche eine translatorische Bewegung und eine Drehbewegung erlaubt, ist es auf einfache Weise möglich das Messer derart auszubilden, dass sowohl eine Schneidkraft parallel zu der Schneide der Klinge, als auch eine Schneidkraft, die rechtwinklig zu der Klinge wirkt, eine Bewegung des Klingenhalters von der ersten Schneidposition in die zweite Schneidposition bewirkt.Due to the bearing of the blade holder, which allows a translational movement and a rotational movement, it is easily possible to form the knife so that both a cutting force parallel to the blade edge, as well as a cutting force acting perpendicular to the blade, a Movement of the blade holder causes from the first cutting position to the second cutting position.

Erfindungsgemäß ist ein Stützelement vorgesehen, mittels welchem der Klingenhalter lösbar an dem Gehäuse abstützbar ist. Das Stützelement kann z.B. dem Klingenhalter oder dem Gehäuse zugeordnet sein. Mittels des Stützelements kann der Klingenhalter an dem Gehäuse lösbar abgestützt werden. Beim Bewegen des Klingenhalters aus der Grundposition in eine erste Schwenkposition kann sich das Stützelement z.B. in Eingriff mit dem Gehäuse befinden oder in Eingriff mit dem Gehäuse bewegt werden. Das Stützelement begrenzt dann z.B. den Freiheitsgrad des Klingenhalters, so dass der Klingenhalter in die erste Schwenkposition gezwungen wird. Das Stützelement kann z.B. ein Auflager bilden.According to the invention, a support element is provided by means of which the blade holder can be detachably supported on the housing. The support element may for example be assigned to the blade holder or the housing. By means of the support member of the blade holder can be releasably supported on the housing. When moving the blade holder from the home position to a first pivot position For example, the support member is engaged with the housing or moved into engagement with the housing. The support element then limits, for example, the degree of freedom of the blade holder, so that the blade holder is forced into the first pivot position. The support element may for example form a support.

Stützelement im Sinne der Erfindung kann ein druckfest oder zugfest beanspruchtes Element sein.Supporting element according to the invention may be a pressure-resistant or tensile-stressed element.

Wird der Klingenhalter, z.B. durch eine Schneidreaktionskraft, aus der ersten Schneidposition in eine zweite Schneidposition bewegt, so kann das Stützelement dadurch außer Eingriff bewegt werden. Der Klingenhalter hat dann wieder einen zusätzlichen Freiheitsgrad, welcher es ihm erlaubt, sich in das Gehäuse zurückzubewegen, obwohl die Handhabe betätigt ist.When the blade holder, e.g. moved by a cutting reaction force from the first cutting position to a second cutting position, the support member can thereby be disengaged. The blade holder then has an additional degree of freedom, which allows it to move back into the housing, although the handle is actuated.

Mittels des Stützelements kann dem Klingenhalter eine bestimmte Bewegung vorgegeben werden kann. Mittels des Stützelements kann ein Abstand zwischen dem Klingenhalter und dem Gehäuse überbrückt werden. Zudem kann mittels des Stützelements eine Sicherheitsfunktion gewährleistet werden, wobei sich die Klinge bei betätigter Handhabe in das Gehäuse in die Sicherheitsposition zurückbewegt, wenn die Schneidreaktionskraft auf die Klinge einen bestimmten Wert unterschreitet. Dies ist z.B. möglich, weil der Eingriff des Stützelements lösbar ist. Das Lösen des Eingriffs des Stützelements kann z.B. durch die Schneidreaktionskraft, auch Schneidkraft genannt, erfolgen.By means of the support member, the blade holder a certain movement can be specified. By means of the support member, a distance between the blade holder and the housing can be bridged. In addition, a safety function can be ensured by means of the support element, wherein the blade moves back into the safety position when the handle is actuated into the housing when the cutting reaction force on the blade falls below a certain value. This is e.g. possible because the engagement of the support element is releasable. The release of the engagement of the support element may e.g. by the cutting reaction force, also called cutting force done.

Die Handhabe wird dann automatisch in die unbetätigte Position bewegt, sobald der Benutzer keine Kraft mehr auf die Handhabe ausübt.According to a further embodiment of the invention, the handle is loaded by a spring element in the unactuated position. The handle is then automatically moved to the unactuated position as soon as the user no longer exerts any force on the handle.

Gemäß einer weiteren Ausführungsform ist ein Stützelement vorgesehen, welches dem Klingenhalter oder dem Gehäuse zugeordnet ist, mittels welchem der Klingenhalter wenigstens in der ersten Schneidposition an dem Gehäuse lösbar abstützbar ist. Das Stützelement kann den Freiheitsgrad des Klingenhalters begrenzen. Es kann ein Auflager bilden, um welches das Betätigungselement wippenartig schwenkbar ist. Das Stützelement kann z.B. an dem Betätigungselement befestigt sein und mit dem Gehäuse wenigstens mittelbar in Eingriff bringbar sein. Das Stützelement kann z.B. mit einem Anschlagelement zusammenwirken, das an dem Gehäuse befestigt ist. Alternativ kann das Stützelement z.B. an dem Gehäuse befestigt sein und mit dem Klingenhalter in Eingriff bringbar sein. An dem Klingenhalter kann z.B. ein Anschlagelement vorgesehen sein, welches mit dem Stützelement zusammenwirkt.According to a further embodiment, a support element is provided, which is assigned to the blade holder or the housing, by means of which the blade holder is detachably supported on the housing at least in the first cutting position.

Einer weiteren Ausführungsform gemäß ist das Stützelement lösbar mit dem Gehäuse oder dem Klingenhalter in Eingriff bringbar. Mittels dieser Ausführungsform kann der Freiheitsgrad des Klingenhalters bei Eingriff des Stützelements in bestimmter Weise begrenzt werden und durch Lösen des Stützelements wieder freigegeben werden. Der Klingenhalter kann sich z.B. aus der zweiten Schneidposition in Richtung Sicherheitsposition zurück bewegen, wenn der Eingriff des Stützelements gelöst ist, unabhängig davon, ob sich die Handhabe in der betätigten Position befindet. Das mit dem Klingenhalter bewegungsverbundene Betätigungselement kann sich bei der Bewegung des Klingenhalters in die Sicherheitsposition in die Grundposition bewegen.According to another embodiment, the support member is releasably engageable with the housing or the blade holder.

Dabei kann das Stützelement sich z.B. an die zweite Führungsfläche anlegen, welche das Stützelement zur der ersten Führungsfläche führt.According to a further embodiment, the mating surface is formed adjacently at least one guide surface which guides the support element into engagement with the mating surface, in particular the bearing seat. For example, two guide surfaces may be provided, wherein a first guide surface guides the support element into the recess during the movement of the blade holder into the first cutting position. After the support element has come out of engagement with the recess, the blade holder, for example, can move back in the direction of home position when operated handle. In this case, the support element can be applied, for example, to the second guide surface, which guides the support element to the first guide surface.

Gemäß einer weiteren Ausgestaltung der Erfindung ist das Stützelement von wenigstens einem Federelement in eine Neutralposition belastet. Bei einem Verschwenken des Stützelements in wenigstens eine Drehrichtung wird das Stützelement dann zurück in die Neutralposition belastet.

An dem Klingenhalter 13 ist ein Zylinderstumpf 24 angeformt, welcher in einer in der Handhabe 12 ausgebildeten Nut 25 geführt ist. Der Klingenhalter 13 bildet mit der Nut 25 ein Gelenk G2. Der Klingenhalter 13 ist auf diese Weise parallel zu einer Längsmittelachse m der Nut 25 in die Richtungen x1, x2 verschiebbar und um eine Schwenkachse a2 des Zylinderstumpfes 24 in die Richtungen q1, q2 (siehe Fig. 1) schwenkbar. Der Klingenhalter 13 kann zwischen einer Sicherheitsposition (siehe Fig. 1), einer ersten Schneidposition (siehe Fig. 2) und einer zweiten Schneidposition (siehe Fig. 3) bewegt werden. Der Klingenhalter 13 weist eine nicht näher dargestellte Halterung für eine Klinge 27 auf.On the blade holder 13, a cylinder stub 24 is formed, which is guided in a groove 12 formed in the handle 12. The blade holder 13 forms with the groove 25 a joint G2. The blade holder 13 is displaceable in this way parallel to a longitudinal center axis m of the groove 25 in the directions x1, x2 and about a pivot axis a2 of the cylinder stub 24 in the directions q1, q2 (see Fig. 1 ) pivotable. The blade holder 13 can between a safety position (see Fig. 1 ), a first cutting position (see Fig. 2 ) and a second cutting position (see Fig. 3 ) are moved. The blade holder 13 has a holder, not shown, for a blade 27.

In der Sicherheitsposition ist der Klingenhalter 13 derart angeordnet, dass die Klinge 27 in das Gehäuse 11 zurückgezogen und für einen Benutzer unzugänglich ist. In der Sicherheitsposition ragt die Klinge 27 nicht aus dem Gehäuse 11 heraus (siehe Fig. 1). In der ersten Schneidposition und in der zweiten Schneidposition ragt die Klinge 27 aus dem Gehäuse 11 heraus (siehe die Fig. 2 und 3).In the safety position, the blade holder 13 is arranged such that the blade 27 is retracted into the housing 11 and inaccessible to a user. In the safety position, the blade 27 does not protrude out of the housing 11 (see Fig. 1 ). In the first cutting position and in the second cutting position, the blade 27 protrudes out of the housing 11 (see FIGS Fig. 2 and 3 ).

Ein hinterer Fortsatz 26 des Klingenhalters 13 ist mittels eines Gelenks G3 mit einer Schwenkachse a3 fest mit einem ersten Endbereich 49 des Betätigungselements 14 verbunden. Der Klingenhalter 13 ist mittels des Gelenks G3 relativ zu dem Betätigungselement 14 schwenkbar. Das Betätigungselement 14 und der Klingenhalter 13 sind miteinander bewegungsverbunden.A rear extension 26 of the blade holder 13 is connected by means of a joint G3 with a pivot axis a3 fixed to a first end portion 49 of the actuating element 14. Of the Blade holder 13 is pivotable relative to the actuating element 14 by means of the joint G3. The actuator 14 and the blade holder 13 are movably connected to each other.

Das Betätigungselement 14 ist an einem zweiten Endbereich 50 mit einem Gelenk G4, das eine Schwenkachse a4 aufweist, schwenkbar an der Handhabe 12 gelagert. Das Betätigungselement 14 kann auf diese Weise bezüglich der Handhabe 14 in die Richtungen p1, p2 geschwenkt werden. Ein elastisch verformbares Element 28, z.B. eine Zugfeder, belastet das Betätigungselement 14 in die z.B. in Fig. 1 dargestellte Grundposition, in welcher das Betätigungselement 14 den Klingenhalter 13 in der Sicherheitsposition hält. Das Federelement 28 ist an einem Befestigungsmittel 30 des Betätigungselements 14 und an einem Befestigungsmittel 32 der Handhabe 12 befestigt.The actuating element 14 is pivotably mounted on the handle 12 at a second end region 50 with a joint G4, which has a pivot axis a4. The actuating element 14 can be pivoted in this way with respect to the handle 14 in the directions p1, p2. An elastically deformable element 28, for example a tension spring, loads the actuating element 14 into the, for example, in FIG Fig. 1 illustrated basic position in which the actuator 14 holds the blade holder 13 in the safety position. The spring element 28 is fastened to a fastening means 30 of the actuating element 14 and to a fastening means 32 of the handle 12.

Ein Stützelement 33 ist mit einem Schwenkgelenk G5 mit einer Schwenkachse a5 schwenkbar an dem Klingenhalter 14 gelagert. Ein Endbereich 34 des Stützelements 33 liegt in der in Fig. 1 dargestellten Grundposition des Betätigungselements 14 an einer Oberfläche 35 einer Gehäusestruktur 31 in Form einer Aussparung 36 an, wobei die Gehäusestruktur 31 einen Lagersitz für den Endbereich 34 bildet. Das Stützelement 33 ist von wenigstens einem nicht dargestellten Federelement in eine Neutralposition belastet.A support element 33 is pivotally mounted on the blade holder 14 with a pivot joint G5 having a pivot axis a5. An end region 34 of the support element 33 lies in the in Fig. 1 illustrated basic position of the actuating element 14 on a surface 35 of a housing structure 31 in the form of a recess 36, wherein the housing structure 31 forms a bearing seat for the end portion 34. The support member 33 is loaded by at least one spring element, not shown, in a neutral position.

Wird die Handhabe 12 aus der unbetätigten Position gemäß Fig. 1 in Richtung x1 in die betätigte Position gemäß Fig. 2 bewegt, so bewegt sich der Endbereich 34 des Stützelements 33 in Kontakt mit der Fläche 35 in den Eingriff mit einer Aussparung 36. Der Aussparung 36 benachbart weist die Gehäusestruktur 31 einen Vorsprung 37 auf. Durch den Eingriff des Stützelements 33 mit der Aussparung 36 wird bei dem Bewegen der Handhabe 12 aus der unbetätigten in die betätigte Position das Betätigungselement 14 um die Achse a4 in Richtung p1 in die in Fig. 2 dargestellte erste Schwenkposition geschwenkt.If the handle 12 from the unactuated position according to Fig. 1 in the direction x1 in the actuated position according to Fig. 2 moved, the end portion 34 of the support member 33 moves in contact with the surface 35 into engagement with a recess 36. The recess 36 adjacent the housing structure 31 has a projection 37 on. By the engagement of the support member 33 with the recess 36 is in the movement of the handle 12 from the unactuated to the actuated position the actuator 14 about the axis a4 in the direction p1 in the in Fig. 2 pivoted illustrated first pivot position.

Nach dem Eingriff des Endbereichs 34 in die Aussparung 36, wodurch der Kontakt zwischen dem Stützelement 33 und der Gehäuseschale 11 hergestellt ist, wird durch das Stützelement 33 über das Gelenk G5 eine Kraft auf den Klingenhalter 13 ausgeübt, welche bei der Bewegung der Handhabe 12 in Richtung x1 das Betätigungselement 14 veranlasst, bezüglich der Handhabe 12 in Richtung p1 zu schwenken. Das Stützelement wird dabei auf Druck belastet.After the engagement of the end portion 34 in the recess 36, whereby the contact between the support member 33 and the housing shell 11 is made, a force is exerted on the blade holder 13 by the support member 33 via the joint G5, which in the movement of the handle 12 in Direction x1 causes the actuator 14 to pivot with respect to the handle 12 in the direction of p1. The support element is loaded on pressure.

Das Schwenken des Betätigungselements 14 von der Grundposition in die erste Schwenkposition erfolgt entgegen der Federkraft des Federelements 28. Während der Bewegung des Betätigungselements 14 von der Grundposition in die erste Schwenkposition wird der Klingenhalter 13 im Uhrzeigersinn in Richtung q1 gemäß Fig. 1 um die Schwenkachse a2 geschwenkt. Ferner wird der Klingenhalter 13 um die Schwenkachse a3 relativ zu dem Betätigungselement 14 gemäß der Fig. 1 und 2 im Uhrzeigersinn verschwenkt. Ferner wird der fest mit dem Klingenhalter 13 verbundene Zylinderstumpf 24 in der in der Handhabe 12 ausgebildeten Nut 25 in Richtung x1 bewegt. Während sich der Zylinderstumpf 24 in der Sicherheitsposition des Klingenhalters 13 gemäß Fig. 1 an einem Endbereich 52 der Nut 25 befindet, ist der Zylinderstumpf 24 in der ersten Schneidposition des Klingenhalters 13 gemäß Fig. 2 in Richtung eines Endbereichs 53 der Nut 25 bewegt.The pivoting of the actuator 14 from the home position to the first pivotal position occurs against the spring force of the spring member 28. As the actuator 14 moves from the home position to the first pivot position, the blade holder 13 rotates clockwise in the direction of FIG Fig. 1 pivoted about the pivot axis a2. Further, the blade holder 13 about the pivot axis a3 relative to the actuating element 14 according to the Fig. 1 and 2 pivoted clockwise. Further, the cylinder stump 24 fixedly connected to the blade holder 13 is moved in the direction of x1 in the groove 25 formed in the handle 12. While the cylinder stub 24 in the safety position of the blade holder 13 according to Fig. 1 is located at an end portion 52 of the groove 25, the cylinder stub 24 is in the first cutting position of the blade holder 13 according to Fig. 2 in the direction of an end portion 53 of the groove 25 moves.

Befindet sich das Betätigungselement 14 in der ersten Schwenkposition gemäß Fig. 2, ragt die Klinge 27 aus einer Öffnung 47 des Messers 10 heraus. Bei dem Schwenken des Betätigungselements 14 in die erste Schwenkposition wird ferner das Stützelement 33 relativ zu dem Klingenhalter 13 entgegen der Federkraft des nicht dargestellten Federelementes in Drehrichtung u1 geschwenkt.Is the actuator 14 in the first pivot position according to Fig. 2 , the blade 27 protrudes out of an opening 47 of the blade 10. In the pivoting of the actuating element 14 in the first pivot position, the support member 33 is further relative pivoted to the blade holder 13 against the spring force of the spring element, not shown, in the direction of rotation u1.

Wirkt in der in Fig. 2 dargestellten Position des Messers 10 eine Schneidreaktionskraft F auf die Klinge 27, so verschwenkt der Klingenhalter 13 aus der ersten Schneidposition um die Schwenkachse a2 im Uhrzeigersinn in Richtung q1 in die in Fig. 3 dargestellte zweite Schneidposition. Es sei darauf hingewiesen, dass die Schneidreaktionskraft auf die Klinge 27 auch in einer anderen, als der eingezeichneten Richtung auf die Klinge 27 wirken kann. In Fig. 2 wirkt die Kraft F rechtwinklig auf die Schneide S. Die Schneidreaktionskraft F kann Anteile aufweisen, die parallel zu einer Schneide S der Klinge 27 wirken sowie andere Anteile, die rechtwinklig zu der Schneide S wirken.Acts in the in Fig. 2 shown position of the knife 10 a cutting reaction force F on the blade 27, the blade holder 13 pivots from the first cutting position about the pivot axis a2 in the clockwise direction q1 in the in Fig. 3 illustrated second cutting position. It should be noted that the cutting reaction force on the blade 27 may also act on the blade 27 in a direction other than the indicated direction. In Fig. 2 the force F acts at right angles to the cutting edge S. The cutting reaction force F can have portions which act in parallel to a blade S of the blade 27 as well as other portions which act at right angles to the blade S.

Da der Klingenhalter 13 über das Gelenk G3 mit dem Betätigungselement 14 bewegungsverbunden ist, wird das Betätigungselement 14 dabei in die in Fig. 3 dargestellte zweite Schwenkposition bewegt. Das Stützelement 33 bewegt sich aufgrund der Schwenkbewegung des Betätigungselements 14 in die zweite Schwenkposition außer Eingriff mit der Aussparung 36 und wird von dem nicht dargestellten Federelement relativ zu dem Betätigungselement 14 in Richtung u2 in die in Fig. 3 dargestellte Neutralposition bewegt.Since the blade holder 13 is movably connected via the joint G3 with the actuating element 14, the actuating element 14 is thereby in the in Fig. 3 shown second pivot position moves. The support member 33 moves due to the pivotal movement of the actuating element 14 in the second pivot position out of engagement with the recess 36 and is of the spring element, not shown, relative to the actuating element 14 in the direction u2 in the in Fig. 3 shown neutral position moves.

Sobald die Schneidkraft F kleiner ist als die Federkraft des Federelements 28, was z.B. bei nachlassendem Kontakt zwischen der Klinge 27 und einem nicht dargestelltem Schneidgut der Fall ist, wird das Betätigungselement 14 von dem Federelement 28 aus der zweiten Schwenkposition um die Schwenkachse a4 im Uhrzeigersinn in Richtung p2 in die in Fig. 4 dargestellte Grundposition bewegt, obwohl die Handhabe 12 sich in der betätigten Position befindet. Dabei wird der Klingenhalter 13 in Richtung x2 in die Sicherheitsposition bewegt, in welcher die an dem Klingenhalter 13 befestigte Klinge 27 in den Aufnahmeraum A des Gehäuses 11 zurückgezogen ist. Bei der vorerwähnten Bewegung des Betätigungselements 14 von der zweiten Schwenkposition in die Grundposition wird der Klingenhalter 13 ferner um die Schwenkachse a2 in Richtung q2 geschwenkt.As soon as the cutting force F is smaller than the spring force of the spring element 28, which is the case, for example, with decreasing contact between the blade 27 and a not shown Schneidgut, the actuating element 14 of the spring element 28 from the second pivot position about the pivot axis a4 clockwise in Direction p2 into the in Fig. 4 shown basic position moves, although the handle 12 is in the actuated position. In this case, the blade holder 13 is moved in the direction x2 in the safety position, in which the blade 27 fixed to the blade holder 13 is retracted into the accommodating space A of the housing 11. In the aforementioned movement of the operating member 14 from the second pivot position to the home position, the blade holder 13 is further pivoted about the pivot axis a2 in the direction q2.

In der in Fig. 4 dargestellten Grundposition des Betätigungselements 14 liegt der Endbereich 34 der Stütze 33 an einer Innenfläche 48 des Gehäuses 11 an. Der Klingenhalter 13 ist in der Sicherheitsposition angeordnet, in welcher die Klinge 27 für den Benutzer unzugänglich in das Gehäuse 11 zurückgezogen ist. Das nicht dargestellte Federelement ist gespannt und belastet die Stütze 33 gegen die Innenfläche 48 des Gehäuses 11.In the in Fig. 4 illustrated basic position of the actuating element 14 is the end portion 34 of the support 33 on an inner surface 48 of the housing 11 at. The blade holder 13 is arranged in the safety position, in which the blade 27 is retracted inaccessible to the user in the housing 11. The spring element, not shown, is tensioned and loads the support 33 against the inner surface 48 of the housing eleventh

Sobald der Benutzer die Handhabe 12 freigibt, wird die Handhabe 12 von dem Federelement 19 in Richtung x2 in die unbetätigte Position bewegt. Dabei gleitet der Endbereich 34 des Stützelements 33 entlang der Innenfläche 48 und wird von der Innenfläche 48 zu der Außenfläche 35 geführt.As soon as the user releases the handle 12, the handle 12 is moved by the spring element 19 in the direction x2 in the unactuated position. In this case, the end region 34 of the support element 33 slides along the inner surface 48 and is guided from the inner surface 48 to the outer surface 35.

Die unbetätigte Position der Handhabe ist in Fig. 1 dargestellt. Gemäß Fig. 1 liegt das Stützelement 33 wieder mit dem Endbereich 34 an der Außenfläche 35 an.The unactuated position of the handle is in Fig. 1 shown. According to Fig. 1 is the support member 33 again with the end portion 34 on the outer surface 35 at.
