Aus der DE 37 36 968 C2 ist ein Messer bekannt, bei welchem die Klinge zwischen zwei Seitenteilen lösbar gehalten wird. Die Seitenteile des Klingenträgers sind von Innenwänden geführt. Ein Klingenwechsel ist erst möglich, nachdem der Klingenträger über eine hintere Gehäuseöffnung von dem Gehäuse gelöst wurde. Anschließend können die Seitenteile voneinander getrennt werden, so dass die Klinge entnehmbar ist und eine andere Klinge zwischen den Seitenteilen angeordnet werden kann. Der Klingenträger wird dann wieder in das Gehäuse eingesetzt.From the DE 37 36 968 C2 a knife is known in which the blade is releasably held between two side parts. The side parts of the blade carrier are guided by inner walls. A blade change is only possible after the blade carrier has been released from the housing via a rear housing opening. Subsequently, the side parts can be separated from each other so that the blade can be removed and another blade can be arranged between the side parts. The blade carrier is then inserted back into the housing.

Bei dem Messer gemäß der DE 10 2005 049 411 B3 ist die Klinge sowohl in der Ruhe-, als auch in der Schneidposition zwischen zwei Seitenteilen gehalten. Der Klingenträger kann in eine Klingenwechselposition bewegt werden, indem er um einen bestimmten Weg über die Schneidposition hinaus nach vorne geschoben wird. In der Klingenwechselposition kann ein Seitenteil bezüglich des anderen Seitenteils abgespreizt werden, so dass die Klinge entnommen werden kann.In the knife according to the DE 10 2005 049 411 B3 the blade is held between two side parts both in the resting position and in the cutting position. The blade carrier can be moved to a blade changing position by being pushed forward a certain distance beyond the cutting position. In the blade changing position, one side part can be relative to the other Sides are spread apart so that the blade can be removed.

Aus der EP 1 864 766 A1 ist ein Messer bekannt, welches ein Gehäuse sowie einen verschieblich an dem Gehäuse gehaltenen Gehäusedeckel aufweist. Durch Verschieben des Deckels in eine Offenposition ist der Zugriff auf den in der hinteren Sicherheitsposition befindlichen Klingenträger möglich und die in einem Klingensitz des Klingenträgers gehaltene Klinge kann aus einem Lagersitz des Klingenträgers entnommen werden.From the EP 1 864 766 A1 a knife is known, which has a housing and a housing cover held displaceably on the housing. By moving the lid to an open position, access to the blade carrier located in the rear safety position is possible and the blade held in a blade seat of the blade carrier can be removed from a bearing seat of the blade carrier.

Es ist Aufgabe der Erfindung, ein Messer zu schaffen, das einfach herstellbar ist, bei welchem der Klingenwechsel einfach durchzuführen ist und bei welchem die Klinge während des Gebrauchs des Messers fest in dem Lagersitz gehalten ist.It is an object of the invention to provide a knife that is easy to manufacture, in which the blade change is easy to perform and in which the blade is held firmly in the bearing seat during use of the knife.

Die Aufgabe wird gelöst durch ein Messer mit den Merkmalen des Patentanspruchs 1.The object is achieved by a knife having the features of patent claim 1.

Das Prinzip der Erfindung wird nachfolgend erläutert. In einem Messergehäuse ist ein Klingenträger gelagert. An dem Klingenträger ist eine Klinge lösbar befestigbar. Der Klingenträger kann z.B. zwischen einer Sicherheitsposition, in welcher die Klinge für den Benutzer unzugänglich in das Gehäuse zurückgezogen ist und einer Schneidposition, in welcher die Klinge aus dem Gehäuse herausragt, bewegbar sein. Der Klingenträger weist mindestens zwei Halteteile auf, zwischen denen die Klinge gehalten werden kann. Die Halteteile des Klingenträgers sind zueinander relativbeweglich ausgebildet. In einer Klingenhalteposition der Halteteile ist die Klinge fest zwischen den Halteteilen gehalten. In einer Klingenwechselposition sind wenigstens Bereiche der Halteteile derart voneinander beabstandet, dass ein Klingenwechsel möglich ist. Die Halteteile können z.B. schwenkbeweglich zueinander sein. Alternativ können die Halteteile z.B. zueinander verschiebbar sein.The principle of the invention will be explained below. In a knife housing, a blade carrier is mounted. At the blade carrier a blade is detachably fastened. For example, the blade carrier may be movable between a safety position in which the blade is retracted into the housing inaccessible to the user and a cutting position in which the blade protrudes from the housing. The blade carrier has at least two holding parts, between which the blade can be held. The holding parts of the blade carrier are mutually relatively movable. In a blade holding position of the holding parts, the blade is firmly held between the holding parts. In a blade changing position at least portions of the holding parts are spaced apart from each other such that a blade change is possible. The holding parts can, for example, be pivotable relative to one another. Alternatively, the holding parts may be displaced to each other, for example.

Das Gehäuse umfasst zwei zueinander bewegliche Gehäuseteile. Die Teilungskontur zwischen den Gehäuseteilen kann z.B. parallel zu einer Messerlängsachse ausgebildet sein. Die Gehäuseteile können z.B. translatorisch zueinander verschiebbar sein. Die Gehäuseteile können z.B. in Richtung der Gehäuselängsachse zueinander bewegbar sein. Alternativ können die Gehäuseteile z.B. zueinander verschwenkbar sein. Das Gehäuse ist durch eine Bewegung eines ersten Gehäuseteils relativ zu einem zweiten Gehäuseteil zwischen einer Offenposition und einer Geschlossenposition bewegbar. In der Offenposition ist der Zugriff auf einen Innenraum des Gehäuses möglich, in welchem der Klingenträger angeordnet ist. In der Geschlossenposition ist der Gehäuseinnenraum für den Benutzer unzugänglich. Die Bewegung des Gehäuses in die Offenposition kann z.B. lediglich dann möglich sein, wenn der Klingenträger in der Sicherheitsposition angeordnet ist.The housing comprises two mutually movable housing parts. The dividing contour between the housing parts may e.g. be formed parallel to a blade longitudinal axis. The housing parts may e.g. be translatable to each other. The housing parts may e.g. be mutually movable in the direction of the housing longitudinal axis. Alternatively, the housing parts may be e.g. be pivoted to each other. The housing is movable by a movement of a first housing part relative to a second housing part between an open position and a closed position. In the open position access to an interior of the housing is possible, in which the blade carrier is arranged. In the closed position, the housing interior is inaccessible to the user. The movement of the housing to the open position may be e.g. only be possible if the blade carrier is arranged in the safety position.

Die Geschlossenposition des Gehäuses ist z.B. der Klingenhalteposition des Klingenträgers zugeordnet und die Offenposition des Gehäuses ist z.B. der Klingenwechselposition des Klingenträgers zugeordnet.By means of a drive device, the side parts of the blade carrier between the blade holding position and the blade changing position are moved by the relative movement of the housing parts between the open position and the closed position. The closed position of the housing is e.g. the blade holding position of the blade carrier assigned and the open position of the housing is e.g. associated with the blade changing position of the blade carrier.

Die Antriebsvorrichtung ist vorgesehen, um bei einer Relativbewegung der Gehäuseteile eine Relativbewegung der Halteteile des Klingenträgers zu bewirken. Die Bewegungsübertragung von dem Gehäuse auf den Klingenträger kann z.B. lediglich in einem Bereich der Bewegung zwischen der Offenposition und der Geschlossenposition des Gehäuses stattfinden. Alternativ kann eine Bewegungsübertragung kontinuierlich während der gesamten Bewegung zwischen der Geschlossenposition und der Offenposition erfolgen.The drive device is provided to effect a relative movement of the holding parts of the blade carrier during a relative movement of the housing parts. The transmission of motion from the housing to the blade carrier may be e.g. take place only in a range of movement between the open position and the closed position of the housing. Alternatively, a motion transmission may occur continuously throughout the movement between the closed position and the open position.

Die Antriebsvorrichtung kann z.B. eine Kupplungsvorrichtung für eine lösbare Bewegungsverbindung zwischen wenigstens einem Gehäuseteil und wenigstens einem Halteteil des Klingenträgers umfassen. Außerdem kann die Antriebsvorrichtung z.B. ein Getriebe umfassen. Des Weiteren kann die Antriebsvorrichtung eine Umwandlungsvorrichtung umfassen, mit welcher eine Bewegungsform in eine andere Bewegungsform umwandelbar ist.The drive device may comprise, for example, a coupling device for a detachable movement connection between at least one housing part and at least one holding part of the blade carrier. In addition, the drive device such as a transmission include. Furthermore, the drive device may comprise a conversion device with which a movement form can be converted into another form of movement.

Das Gehäuse umfasst eine Lagervorrichtung, mittels welcher wenigstens zwei Gehäuseteile zwischen einer Offenposition und einer Geschlossenposition bewegbar aneinander gelagert sind. Z.B. weist das erste Gehäuseteil erste Lagermittel auf, welche mit zweiten Lagermitteln zusammenwirken, die dem zweiten Gehäuseteil zugeordnet sind. Die Lagervorrichtung kann z.B. als Gleitlager ausgebildet sein. Die ersten Lagermittel können z.B. schienenartig an den zweiten Lagermitteln geführt sein. Mittels der Lagervorrichtung kann das erste Gehäuseteil an dem zweiten Gehäuseteil bewegbar befestigt sein. Z.B. können die ersten Lagermittel und die zweiten Lagermittel nach Art einer Nut / Feder-Verbindung ausgebildet sein, wobei die Verbindung eine Relativbewegung zwischen dem ersten Gehäuseteil und dem zweiten Gehäuseteil gestattet. Alternativ kann die Lagervorrichtung z.B. von einem Schwenklager gebildet sein. Wenigstens zwei Gehäuseteile sind z. B. relativ zueinander schwenkbar.The housing comprises a bearing device, by means of which at least two housing parts are movably supported between an open position and a closed position. For example, the first housing part has first bearing means, which cooperate with second bearing means, which are associated with the second housing part. The storage device may e.g. be designed as a sliding bearing. The first storage means may e.g. be guided like a rail on the second bearing means. By means of the bearing device, the first housing part may be movably attached to the second housing part. For example, the first bearing means and the second bearing means may be formed in the manner of a tongue and groove connection, the connection allowing a relative movement between the first housing part and the second housing part. Alternatively, the storage device may be e.g. be formed by a pivot bearing. At least two housing parts are z. B. pivotable relative to each other.

Halteteil im Sinne der Erfindung ist z.B. ein Teil des Klingenträgers, an welchem eine Anlagefläche für die Klinge ausgebildet ist. Z.B. kann das Halteteil einen Sitz für die Klinge oder einen Teil des Sitzes bilden. Wenigstens zwei Halteteile können z.B. gemeinsam den Klingensitz bilden. In der Klingenwechselposition kann z.B. an einem der Halteteile eine Vormontage der Klinge möglich sein, in welcher die Klinge bereits derart gehalten ist, dass ein bewegen in die Geschlossenposition der Halteteile möglich ist, ohne dass sich die Klinge aus der Vormontageposition löst. Ein erstes Halteteil kann z.B. von einem in dem Messergehäuse verschiebbar gelagerten Aufnahmeteil gebildet sein. An dem ersten Halteteil kann z.B. ein zweites Halteteil bewegbar gelagert sein. Das zweite Halteteil kann z.B. schwenkbar an dem ersten Halteteil gelagert sein. Gemäß einer Alternative sind z.B. das erste Halteteil und das zweite Halteteil an einem gesonderten Aufnahmeteil gelagert. Das erste Halteteil und das zweite Halteteil können z.B. jeweils schwenkbar an dem Aufnahmeteil gelagert sein.Holding part according to the invention is, for example, a part of the blade carrier, on which a contact surface is formed for the blade. For example, the holding part may form a seat for the blade or a part of the seat. For example, at least two holding parts can jointly form the blade seat. In the blade changing position, for example, a pre-assembly of the blade may be possible on one of the holding parts, in which the blade is already held in such a way that a movement into the closed position of the holding parts is possible without the blade detaching from the pre-assembly position. A first holding part may be formed, for example, by a receiving part displaceably mounted in the knife housing. For example, a second holding part may be movably mounted on the first holding part. The second holding part may for example be pivotally mounted on the first holding part. According to one alternative, for example, the first holding part and the second holding part are mounted on a separate receiving part. The first holding part and the second holding part may, for example, each be pivotally mounted on the receiving part.

Der Vorteil der Erfindung besteht darin, dass der Klingenwechsel besonders einfach durchführbar ist. Sobald das Gehäuse in die Offenposition versetzt ist, kann der Klingenwechsel stattfinden, da die Halteteile während der Bewegung der Gehäuseteile in die Offenposition automatisch in die Klingenwechselposition bewegt werden, in welcher die Klinge entnehmbar oder eine Klinge in den Klingensitz einsetzbar ist. Dennoch ist die Klinge in der Klingenhalteposition der Halteteile fest zwischen den Halteteilen gehalten. Denn durch die Bewegung der Gehäuseteile in die Geschlossenposition werden die Halteteile automatisch in die Klingenhalteposition bewegt. Die Verletzungsgefahr wird darüber hinaus gemindert. Bei einigen Messern aus dem Stand der Technik führte der schwierig durchführbare Klingenwechsel häufig zu Verletzungen.The advantage of the invention is that the blade change is particularly easy to carry out. Once the housing is in the open position, the blade change may take place as the retainers are automatically moved to the blade change position during movement of the housing members to the open position, in which the blade is removable or a blade is insertable into the blade seat. Nevertheless, the blade is held firmly in the blade holding position of the holding parts between the holding parts. Because by the movement of the housing parts in the closed position, the holding parts are automatically moved to the blade holding position. The risk of injury is also reduced. In some prior art knives, the difficulty of changing blades has often resulted in injuries.

For example, a translation of the distance traveled, the speed of movement or the actuation force can take place.

Eine weitere Ausgestaltung der Erfindung ist dadurch gekennzeichnet, dass die Antriebsvorrichtung eine Umwandlungsvorrichtung zum Umwandeln der Bewegung wenigstens eines Gehäuseteils in eine andere Bewegung wenigstens eines Halteteils umfasst.

Die Bewegung des ersten Gehäuseteils oder des zweiten Gehäuseteils kann z.B. auf einen Hebelarm übertragen werden. Die translatorische Bewegung eines Gehäuseteils kann z.B. in eine rotatorische Bewegung des Hebels umgewandelt werden. Dafür kann ein Gehäuseteil mit einem Hebelarm in Eingriff bringbar sein und den Hebelarm bei der Bewegung zwischen der Offenposition und der Geschlossenposition verschwenken.The movement of the first housing part or the second housing part may e.g. be transferred to a lever arm. The translatory movement of a housing part can e.g. be converted into a rotational movement of the lever. For a housing part with a lever arm can be brought into engagement and pivot the lever arm in the movement between the open position and the closed position.

For the elastic deformation, a certain mounting force is necessary, e.g. is dimensioned by the construction such that a simple assembly is possible and the bearing axis is held firmly in the bearing seat in the use of the knife. The lever can be easily mounted on the base in this way.

Gemäß einer weiteren Ausführungsform ist dem Gehäuse eine Verriegelungsvorrichtung zugeordnet, die zwischen einer Verriegelungsposition und einer Entriegelungsposition bewegbar ist, wobei in der Verriegelungsposition eine Relativbewegung der Gehäuseteile verhindert wird und in der Entriegelungsposition eine Relativbewegung der Gehäuseteile möglich ist.

In dem Lagersitz 47 ist die Schwenkachse 46 um die geometrische Schwenkachse a schwenkbar gleitgelagert.According to Fig. 2 the blade carrier 12 comprises a base part 20 and a lever 25 with a holding arm 21. By means of a pivot joint G, the lever 25 is pivotally supported on the base part 20. The pivot joint G is formed by a pivot axis 46 of the lever 25 and a bearing seat 47. The bearing seat 47 is formed in the base 20. In the bearing seat 47, the pivot axis 46 is slidably mounted to slide about the geometric pivot axis a.

In Fig. 2 befindet sich der Haltearm 21 in der Klingenhalteposition. In der Klingenhalteposition ist die Klinge 13 fest zwischen einer Sitzfläche 44 des Grundteils 20 und einer Klingenanlagefläche 35 des Haltearms 21 in einem Klingensitz 53 des Grundteils 20 gehalten. Zur formschlüssigen Befestigung der Klinge 13 sind an dem Grundteil 20 Zapfen 22 ausgebildet, welche in Aussparungen 23 des Haltearms 21 eingreifen. Die Zapfen 22 durchgreifen dabei Durchbrechungen 24 in der Klinge 13.In Fig. 2 the holding arm 21 is in the blade holding position. In the blade holding position, the blade 13 is firmly held between a seating surface 44 of the base 20 and a blade abutment surface 35 of the holding arm 21 in a blade seat 53 of the base 20. For the positive fastening of the blade 13, pins 20 are formed on the base part 20, which engage in recesses 23 of the holding arm 21. The pins 22 pass through apertures 24 in the blade thirteenth

Durch Schwenken des Haltearms 21 um die Schwenkachse a in Richtung u1 kann der Haltearm 21 in eine Klingenwechselposition gemäß Fig. 3 bewegt werden. In der Klingenwechselposition kann die Klinge 13 entnommen werden und eine Klinge 13 in den Klingensitz 53 des Klingenträgers 12 eingelegt werden. Aus der in Fig. 3 dargestellten Klingenwechselposition kann der Hebel 25 mit dem Haltearm 21 in Richtung u2 in die Klingenhalteposition gemäß Fig. 2 geschwenkt werden.By pivoting the support arm 21 about the pivot axis a in the direction u1 of the support arm 21 in a blade change position according to Fig. 3 to be moved. In the blade changing position, the blade 13 can be removed and a blade 13 in the blade seat 53 of the blade carrier 12 are inserted. From the in Fig. 3 shown blade change position, the lever 25 with the support arm 21 in the direction u2 in the blade holding position according to Fig. 2 be panned.

In der Geschlossenposition der Gehäuseteile 11a, 11b sind der Haltearm 21 und das Grundteil 20 in der Klingenhalteposition angeordnet und werden von dem Gehäuseinnenraum I zugewandten Gehäuseflächen der Gehäuseteile 11a und 11b in der Geschlossenposition gehalten.In the closed position of the housing parts 11a, 11b, the holding arm 21 and the base part 20 are arranged in the blade holding position, and are held by the housing inner space I facing housing surfaces of the housing parts 11a and 11b in the closed position.

Der Klingenträger 12 ist in Fig. 4 als Einzelteil dargestellt. An dem Grundteil 20 ist eine Aussparung 27 ausgebildet. Die Aussparung 27 erlaubt eine Rastmontage der Schwenkachse 46 in dem Lagersitz 47. Mittels der Aussparung 27, die dem Lagersitz 47 benachbart ist, wird eine elastische Verformung des Grundteils 20 ermöglicht. Aufgrund der elastischen Verformung des Grundteils 20 können an eine Öffnung 48 angrenzende Wandbereiche 49 und 50 (siehe Fig. 5) bei der Montage der Schwenkachse 46 elastisch zurückzuweichen, während die Schwenkachse 46 eine Öffnung 48 des Lagersitzes 47 passiert. Dies ist notwendig, weil ein Durchmesser D der Schwenkachse 46 eine Breite B der Öffnung 48 übersteigt. Sobald die Schwenkachse 46 in dem Lagersitz 47 angeordnet ist, weichen die Wandbereiche 49 und 50, von der elastischen Rückstellkraft des Grundteils 20 veranlasst, in ihre Ausgangslage zurück.The blade carrier 12 is in Fig. 4 shown as a single part. On the base 20, a recess 27 is formed. The recess 27 allows a latching assembly of the pivot axis 46 in the bearing seat 47. By means of the recess 27 which is adjacent to the bearing seat 47, a elastic deformation of the base 20 allows. Due to the elastic deformation of the base part 20 adjacent to an opening 48 wall portions 49 and 50 (see Fig. 5 ) elastically retract during assembly of the pivot axis 46, while the pivot axis 46 passes through an opening 48 of the bearing seat 47. This is necessary because a diameter D of the pivot axis 46 exceeds a width B of the opening 48. Once the pivot axis 46 is disposed in the bearing seat 47, the wall portions 49 and 50, caused by the elastic restoring force of the base 20, yield back to their original position.

In Fig. 4 ist ein Befestigungselement 54 dargestellt, welches zur Befestigung eines nicht dargestellten Federelements an dem Grundteil 20 angeformt ist. Ein zweites, nicht dargestelltes Befestigungselement ist an dem Gehäuse 11 befestigt. Das Federelement belastet den Klingenträger 12 in die Sicherheitsposition.In Fig. 4 a fastener 54 is shown, which is integrally formed on the base 20 for attachment of a spring element, not shown. A second, not shown fastener is attached to the housing 11. The spring element loads the blade carrier 12 in the safety position.

Der Haltearm 21 bildet einen ersten Hebelarm des zweiarmigen Hebels 25. Ein zweiter Hebelarm des Hebels 25 ist von einem Fortsatz 26 gebildet. Der Fortsatz 26 befindet sich in der Klingenhalteposition des Klingenträgers 12 gemäß Fig. 2 in der Bewegungsbahn einer Schulter 28 des ersten Gehäuseteils 11a. Die Schulter 28 ist an dem vorderen Endbereich 29 des ersten Gehäuseteils 11a, dem Innenraum I des Gehäuses 11 zugewandt, angeordnet. Der Fortsatz 26 und die Schulter 28 sind lösbar in Eingriff bringbar und bilden eine erste Kupplungsvorrichtung 33.The holding arm 21 forms a first lever arm of the two-armed lever 25. A second lever arm of the lever 25 is formed by an extension 26. The extension 26 is located in the blade holding position of the blade carrier 12 according to Fig. 2 in the trajectory of a shoulder 28 of the first housing part 11a. The shoulder 28 is arranged on the front end region 29 of the first housing part 11a, facing the interior I of the housing 11. The extension 26 and the shoulder 28 are releasably engageable and form a first coupling device 33rd

Ein Klingenwechsel kann wie folgt durchgeführt werden. Nach einer Betätigung des Druckknopfes 16 kann das erste Gehäuseteil 11a relativ zu dem zweiten Gehäuseteil 11b in Richtung x1 in die Offenposition bewegt werden. Beim Bewegen des Gehäuses 11 von der Geschlossenposition in die Offenposition gerät eine Schulterfläche 36 der Schulter 28 des ersten Gehäuseteils 11a in Kontakt mit dem Fortsatz 26 des Klingenträgers 12 und übt eine Kraft auf den Fortsatz 26 aus.A blade change can be done as follows. After an actuation of the push button 16, the first housing part 11a can be moved relative to the second housing part 11b in the direction x1 in the open position. When moving the housing 11 from the closed position to the open position, a shoulder surface 36 of the shoulder 28 of the first housing part 11a comes into contact with the extension 26 of the blade carrier 12 and exerts a force on the extension 26.

Bei der weiteren Bewegung des Gehäuses 11 in die Offenposition sind das erste Gehäuseteil 11a und der Fortsatz 26 bewegungsverbunden. Es entsteht ein Drehmoment um die Drehachse a, wodurch der Hebel 25 mit dem Haltearm 21 in Richtung u1 in die Klingenwechselposition schwenkt. Eine Schwenkbewegung des Haltearms 21 ist möglich, sobald die dem Innenraum I zugewandte Gehäusefläche des Gehäuseteils 11a den Haltearm 21 nicht mehr in der Klingenhalteposition hält. Es sei noch erwähnt, dass das Aufnahmeteil 20 eine Aussparung 55 aufweist, in welche der Fortsatz 26 bei der Bewegung in die Klingenwechselposition eintauchen kann.During the further movement of the housing 11 in the open position, the first housing part 11a and the extension 26 are connected to motion. The result is a torque about the axis of rotation a, whereby the lever 25 pivots with the support arm 21 in the direction u1 in the blade changing position. A pivoting movement of the holding arm 21 is possible as soon as the housing surface 11a facing the interior I of the housing part 11a no longer holds the holding arm 21 in the blade holding position. It should be noted that the receiving part 20 has a recess 55, in which the extension 26 can immerse in the movement in the blade changing position.

Wird nach Durchführung des Klingenwechsels das erste Gehäuseteil 11a in Richtung x2 relativ zu dem zweiten Gehäuseteil 11b verschoben, gerät eine Außenfläche 30 des ersten Gehäuseteils 11a mit einer Außenfläche 32 des Haltearms 21 in Kontakt und übt eine Kraft auf den Haltearm 21 aus. Das hat zur Folge, dass der Haltearm 21 während der Bewegung des Gehäuses von der Offenposition in die Geschlossenposition um die Schwenkachsse a in Richtung u2 in die Klingenhalteposition geschwenkt wird. In der Klingenhalteposition ist die Klinge 13 fest zwischen dem Grundteil 20 und dem Halteteil 21 gehalten. Die Außenfläche 32 und die Außenfläche 30 bilden eine zweite Kupplungsvorrichtung 34.If, after carrying out the blade change, the first housing part 11a is displaced in the direction x2 relative to the second housing part 11b, an outer surface 30 of the first housing part 11a comes into contact with an outer surface 32 of the holding arm 21 and exerts a force on the holding arm 21. This has the result that the support arm 21 is pivoted during the movement of the housing from the open position to the closed position about the Schwenkachsse a in the direction u2 in the blade holding position. In the blade holding position, the blade 13 is firmly held between the base 20 and the holding part 21. The outer surface 32 and the outer surface 30 form a second coupling device 34.

Sobald sich das erste Gehäuseteil 11a bezüglich des zweiten Gehäuseteils 11b in der Geschlossenposition befindet, rastet der Druckknopf 16 wieder gemäß Fig. 2 in die Aussparung 19 ein und verriegelt das erste Gehäuseteil 11a mit dem zweiten Gehäuseteil 11b.As soon as the first housing part 11a is in the closed position with respect to the second housing part 11b, the push-button 16 locks again in accordance with FIG Fig. 2 into the recess 19 and locks the first housing part 11a with the second housing part 11b.

Es sei noch erwähnt, dass der Fortsatz 26 und die Schulter 28 eine erste Umwandlungsvorrichtung bilden, mittels welcher die translatorische Bewegung des ersten Gehäuseteils 11a bezüglich des zweiten Gehäuseteils 11b in eine rotatorische Bewegung des Halteteils 21 bezüglich des Grundteils 20 umwandelbar ist. Die Außenfläche 30 des Gehäuseteils 11a und die Außenfläche 32 des Haltearms 21 bilden eine zweite Umwandlungsvorrichtung, mittels welcher die translatorische Bewegung des ersten Gehäuseteils 11a bezüglich des zweiten Gehäuseteils 11b in eine rotatorische Bewegung des Halteteils 21 bezüglich des Grundteils 20 umwandelbar ist.It should be noted that the extension 26 and the shoulder 28 form a first conversion device, by means of which the translational movement of the first housing part 11a with respect to the second housing part 11b in a rotational movement of the holding part 21 with respect to the base 20 is convertible. The outer surface 30 of the housing part 11a and the outer surface 32 of the support arm 21 form a second conversion device, by means of which the translational movement of the first housing part 11a with respect to the second Housing part 11 b in a rotational movement of the holding part 21 with respect to the base 20 is convertible.
