Slot-shaped recesses (15) arranged opposite to the side surfaces of the housing accommodate operating projections (20), and an additional recess arranged at a back of the knife accommodates an additional operating projection. The recesses form finger and hand contact surfaces for a user, where the surfaces surround outer surface area of the housing.

Description

Die Erfindung betrifft ein Messer mit einem Messergehäuse gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a knife with a knife housing according to the preamble of claim 1.

Ein solches Messer ist bekannt aus der DE 36 22 343 C2 . In einem Aufnahmekanal des Messergehäuses ist eine Klingenhalterung, welche die Messerklinge aufnimmt, geführt. Die Klingenhalterung weist an beiden Seiten einen Bedienansatz auf, welcher jeweils in einer Aussparung des Gehäuses aufgenommen ist. Mit dem Bedienansatz kann die Klinge entgegen der Rückstellkraft einer Feder aus einer in das Gehäuse zurückgezogenen Position in eine Schneidposition verbracht werden, bei der ein Teil der Klinge zum Schneiden aus einer Gehäuseöffnung herausragt.Such a knife is known from the DE 36 22 343 C2 , In a receiving channel of the blade housing, a blade holder, which receives the knife blade, out. The blade holder has on both sides of an operating lug, which is received in each case in a recess of the housing. With the operating approach, the blade can be moved against the restoring force of a spring from a retracted into the housing position in a cutting position in which a portion of the blade for cutting protrudes from a housing opening.

Dieses Messer hat den Vorteil, dass aufgrund des beidseitigen Bedienansatzes die Bedienung des Messers sowohl für Linkshänder als auch für Rechtshänder möglich ist. Das Messer lässt sich jedoch bei einer horizontalen Schneidbewegung, bei der ein Druck auf den Messerrücken notwendig ist, nur schwierig handhaben.This knife has the advantage that due to the two-sided operating approach, the operation of the knife for both left-handed and right-handed is possible. However, the knife is difficult to handle in a horizontal cutting motion where pressure on the knife back is necessary.

Ein Messer, das aus offenkundiger Vorbenutzung bekannt ist, weist ebenfalls eine translatorisch in einem Aufnahmekanal des Messergehäuses geführte Klingenhalterung auf. Der Gehäuserücken weist eine Aussparung auf, welche von einem Bedienungsansatz durchgriffen wird, der mit der Klingenhalterung verbunden ist. Der Bedienungsansatz übergreift sattelartig das Messergehäuse. Das Messer ist daher sowohl für Rechts- als auch für Linkshänder geeignet und gestattet darüber hinaus Horizontalschnitte, bei denen ein Daumendruck auf den Messerrücken ausgeübt werden muss.A knife, which is known from public prior use, also has a translationally guided in a receiving channel of the blade housing blade holder. The housing back has a recess which is penetrated by an operating set, which is connected to the blade holder. The operating instructions overlap the knife housing like a saddle. The knife is therefore suitable for both right- and left-handed and also allows horizontal cuts, where a thumb pressure must be exerted on the back of the knife.

Nachteilig an dem Messer ist jedoch, dass das Messer nur schwierig handhabbar ist. Denn bei einem Bewegen des Bedienansatzes beispielsweise mit dem Daumen kollidiert der Bedienansatz an anderer Stelle mit der das Gehäuse umgreifenden Hand.A disadvantage of the knife, however, is that the knife is difficult to handle. For example, when moving the operating approach with the thumb of the operating approach collides elsewhere with the hand enclosing the housing.

Ausgehend von dem erstgenannten Stand der Technik ist es daher Aufgabe der Erfindung, ein Messer zu schaffen, das in der Handhabung verbessert ist.Starting from the first-mentioned prior art, it is therefore an object of the invention to provide a knife that is improved in handling.

Die Aufgabe wird gelöst mit den Merkmalen des Anspruchs 1 insbesondere mit den Merkmalen des Kennzeichenteils.The object is achieved with the features of claim 1, in particular with the features of the characterizing part.

Das wesentliche Prinzip der Erfindung besteht darin, dass das Messergehäuse nunmehr drei schlitzartige Aussparungen aufweist, in welchen jeweils ein Betätigungsansatz für die Klingenhalterung aufgenommen ist. Die Außenflächen des Messergehäuses, welche die Aussparungen umgeben, bilden Stütz- und Anlageflächen für die Finger des Benutzers. Die Außenfläche des Betätigungsansatzes kann bezüglich der umgebenden Gehäuseaußenfläche zurückversetzt sein oder bündig abschließen. Teilbereiche der Außenflächen des Betätigungsansatzes können auch bezüglich der umgebenden Gehäuseaußenfläche vorragen.The essential principle of the invention is that the blade housing now has three slot-like recesses, in each of which an operating lug for the blade holder is added. The outer surfaces of the blade housing, which surround the recesses, form supporting and abutment surfaces for the user's fingers. The outer surface of the actuating lug may be set back or flush with respect to the surrounding housing outer surface. Portions of the outer surfaces of the actuating lug may also protrude with respect to the surrounding housing outer surface.

Vorteil der Erfindung ist, dass das Messer sowohl von Rechts- als auch von Linkshändern in zwei unterschiedlichen Schneidpositionen verwendbar ist. In einer ersten Schneidposition wird der Schneiddruck durch den Handballen auf den Messerrücken aufgebracht, während in einer zweiten Schneidposition der Daumen auf dem Messerrücken anliegt und den Schneiddruck bewirkt.Advantage of the invention is that the knife can be used by both right and left-handers in two different cutting positions. In a first cutting position, the cutting pressure is applied by the palm of the hand on the back of the knife, while in a second cutting position, the thumb rests on the back of the knife and causes the cutting pressure.

Gemäß einer ersten Ausführungsform ragen die umgebenden Gehäuseaußenflächenbereiche bezüglich des Betätigungsansatzes vor, während der Betätigungsansatz wenigstens teilweise gegenüber den Gehäuseaußenflächenbereichen versenkt angeordnet ist. Weil die umgebenden Außenflächen, welche Stützflächen für die Benutzerhand bilden, gegenüber dem Betätigungsansatz vorragen, überspannt die Benutzerhand brückenartig die Aussparung und kommt daher bei der Bedienung eines Betätigungsansatzes nicht ungewollt mit den anderen Betätigungsansätzen in Kontakt.According to a first embodiment, the surrounding housing outer surface regions protrude with respect to the actuating lug, while the actuating lug is at least partially recessed with respect to the housing outer surface regions. Because the surrounding outer surfaces, which form supporting surfaces for the user's hand, protrude from the actuating lug, the user's hand spans the recess in a bridge-like manner and therefore does not come unintentionally in contact with the other actuation approaches when operating an actuation approach.

Gemäß einer weiteren Ausführungsform weist wenigstens ein Betätigungsansatz einen Wulst auf, welcher gegenüber einer Bedienfläche des Betätigungsansatzes vorragt. Der Wulst bildet einen Anschlag für den Bedienfinger, wodurch ein Abrutschen der Finger verhindert wird und der Bedienansatz leichter verschiebbar ist. Der Wulst ragt gegenüber der Bedienfläche vor. Er kann, muss aber nicht über die umgebenden Außenflächen des Messergehäuses hinausragen. Es ist also möglich, dass er gegenüber der Bedienfläche vorragt, jedoch bezüglich der umgebenden Außenfläche versenkt ist.According to a further embodiment, at least one actuating lug has a bead, which protrudes with respect to a control surface of the actuating lug. The bead forms a stop for the operating finger, whereby slipping of the fingers is prevented and the operating approach is easier to move. The bead protrudes from the control surface. He can, but does not have to protrude over the surrounding outer surfaces of the blade housing. It is therefore possible that it protrudes with respect to the operating surface, but is recessed with respect to the surrounding outer surface.

Gemäß einer weiteren Ausführungsform sind alle Betätigungsansätze einem Betätigungselement zugeordnet. Die Betätigungsansätze können beispielsweise mit dem Betätigungselement verklebt sein oder auf andere Weise angebracht sein, wie z.B. durch Verclipsen. Das Betätigungselement kann beispielsweise fest an der Klingenhalterung angebracht sein oder aber auf andere Weise, beispielsweise mittels einer Kupplung, mit der Klingenhalterung zusammen wirken.According to a further embodiment, all actuation approaches are assigned to an actuating element. For example, the actuation lugs may be glued to the actuator or otherwise attached, such as e.g. by clipping. The actuator may for example be fixedly attached to the blade holder or otherwise act, for example by means of a coupling, with the blade holder together.

Gemäß einer weiteren Ausführungsform sind die Betätigungsansätze und das Betätigungselement einstückig miteinander verbunden. Das einstückige Betätigungselement kann beispielsweise durch Kunststoffspritzguss hergestellt werden.According to a further embodiment, the actuating lugs and the actuating element are integrally connected to each other. The one-piece actuator can be made for example by plastic injection molding.

Gemäß einer weiteren Ausgestaltung der Erfindung weist wenigstens der Messergehäusebereich, in welchem die Aussparungen vorgesehen sind, einen im Wesentlichen rechteckigen Querschnitt auf.According to a further embodiment of the invention, at least the blade housing region, in which the recesses are provided, has a substantially rectangular cross section.

Einer ergonomisch vorteilhaften Ausführung gemäß sind die Eckbereiche des im Wesentlichen rechteckigen Querschnitts abgerundet ausgebildet.According to an ergonomically advantageous embodiment, the corner regions of the substantially rectangular cross-section are rounded.

Einer weiteren Ausgestaltung der Erfindung gemäß weist wenigstens der Messergehäusebereich, in welchem die Aussparungen vorgesehen sind, einen im Wesentlichen ovalen Querschnitt auf.According to a further embodiment of the invention, at least the blade housing region, in which the recesses are provided, has a substantially oval cross-section.

  • Fig. 1 eine schematische Seitenansicht des erfindungsgemäßen Messers,
  • Fig. 2 eine Ansicht gemäß Ansichtspfeil II in Fig. 1,
  • Fig. 3 eine Ansicht gemäß Ansichtspfeil III in Fig. 2 und
  • Fig.4 eine Schnittdarstellung gemäß der Schnittlinie IV-IV in Fig. 1.
Further advantages of the invention will become apparent from the non-cited subclaims and with reference to the description of an embodiment shown in FIGS. Show it:
  • Fig. 1 a schematic side view of the knife according to the invention,
  • Fig. 2 a view according to arrow II in Fig. 1 .
  • Fig. 3 a view according to arrow III in Fig. 2 and

In den Zeichnungen ist ein Messer insgesamt mit der Bezugsziffer 10 bezeichnet. Gleiche Bezugsziffern in den unterschiedlichen Figuren bezeichnen entsprechende Teile.In the drawings, a knife is generally designated by the reference numeral 10. Like reference numerals in the different figures indicate corresponding parts.

Ein solches Messer 10 weist gemäß Fig. 1 im Wesentlichen ein Messergehäuse 11, eine Klingenhalterung 12 mit einer Klinge 13 sowie ein Betätigungselement 14 auf. Das Messergehäuse 11 ist mit etwa schlitzartigen Aussparungen 15, 16 und 17 versehen. Ferner weist das Messergehäuse 11 einen Aufnahmekanal A auf.Such a knife 10 has according to Fig. 1 essentially a blade housing 11, a blade holder 12 with a blade 13 and an actuating element 14. The knife housing 11 is provided with approximately slot-like recesses 15, 16 and 17. Furthermore, the blade housing 11 has a receiving channel A.

In dem Aufnahmekanal A des Messergehäuses 11 ist die Klingenhalterung 12 in bekannter Weise längsverschieblich angeordnet. Die Klingenhalterung 12 kann daher zwischen einer Schneidposition gemäß der Figuren 1 bis 4, in welcher die Klinge 13 teilweise aus einer Öffnung 18 des Messergehäuses 11 hinausragt und einer nicht dargestellten Nichtgebrauchsposition verstellt werden, in welcher die Klinge 13 in den Aufnahmekanal A zurückgezogen ist, so dass eine Schneide S der Klinge 13 keine Gefährdung darstellt. Die Klinge 13 ist in bekannter Weise in der Klingenhalterung 12 aufgenommen. Die Klingenhalterung 12 wird von einer Schraubenfeder F in die Nichtgebrauchsposition belastet.In the receiving channel A of the blade housing 11, the blade holder 12 is arranged longitudinally displaceable in a known manner. The blade holder 12 can therefore between a cutting position according to the FIGS. 1 to 4 in which the blade 13 partially protrudes from an opening 18 of the blade housing 11 and adjusts a non-use position, not shown be, in which the blade 13 is retracted into the receiving channel A, so that an edge S of the blade 13 is not a hazard. The blade 13 is received in the blade holder 12 in a known manner. The blade holder 12 is loaded by a coil spring F in the non-use position.

Der Klingenhalterung 12 ist das Betätigungselement 14 zugeordnet, welches einstückig angeformte Betätigungsansätze 20, 21 und 22 mit Bedienflächen 32, 33, 34 aufweist. Die Betätigungsansätze 20, 21 und 22 sind mit Wulsten 29, 30 und 31 versehen, die eine Anschlagfläche D für einen Bedienfinger des Benutzers darstellen. Das Betätigungselement 14 kann fest an der Klingenhalterung angebracht sein oder aber beispielsweise über ein Kupplungselement mit der Klingenhalterung verbunden sein.The blade holder 12 is associated with the actuating element 14, which integrally molded actuating lugs 20, 21 and 22 with control surfaces 32, 33, 34 has. The actuating lugs 20, 21 and 22 are provided with beads 29, 30 and 31, which constitute a stop surface D for a user's operating finger. The actuator 14 may be fixedly attached to the blade holder or, for example, be connected via a coupling element with the blade holder.

Der Betätigungsansatz 20 ist in der Aussparung 15, der Betätigungsansatz 21 in der Aussparung 16 und der Betätigungsansatz 22 in der Aussparung 17 angeordnet. Das Messer 10 ermöglicht daher die Betätigung der Klingenhalterung 12 in zwei unterschiedlichen Halte-Positionen des Messers 10. In einer Schneidposition wird der Schneiddruck mit dem Handballen auf den Messerrücken R aufgebracht. Die Klingenhalterung 12 kann dann, je nachdem ob das Messer 10 von einem Rechts- oder einem Linkshänder benutzt wird, mittels der Betätigungsansätze 20 oder 21 bedient werden. In einer anderen Schneidposition wird der Schneiddruck mit dem Daumen auf den Messerrücken R aufgebracht. Sowohl Rechts- als auch Linkshänder können dann die Klingenhalterung mittels des Betätigungsansatzes 22 bedienen. Mittels des erfindungsgemäßen Messers ist also eine Bewegung der Klingenhalterung 12 von der Nichtgebrauchs- in die Schneidposition von drei Messergehäuseseiten 23, 24 und 25 her möglich.The actuating lug 20 is arranged in the recess 15, the actuating lug 21 in the recess 16 and the actuating lug 22 in the recess 17. The knife 10 therefore allows the operation of the blade holder 12 in two different holding positions of the knife 10. In a cutting position, the cutting pressure is applied with the heel of the hand on the R back of the knife. The blade holder 12 can then be operated by means of the actuation lugs 20 or 21, depending on whether the knife 10 is being used by a right-handed or a left-handed person. In another cutting position, the cutting pressure is applied with the thumb on the back of the knife R. Both right and left-handers can then operate the blade holder by means of the actuating lug 22. Thus, by means of the knife according to the invention, movement of the blade holder 12 from the non-use position to the cutting position of three cutter-housing sides 23, 24 and 25 is possible.

Die Aussparung 15 ist von Außenflächen 26, die Aussparung 16 von Außenflächen 27 und die Aussparung 17 von Außenflächen 28 des Messergehäuses 11 umgeben. Wie aus den Figuren 1 bis 4 hervorgeht, sind die Betätigungsansätze 20 und 21 sowie die angeformten Wulste 29 und 30 bezüglich ihrer umgebenden Gehäuseaußenflächen 26 und 27 versenkt angeordnet. Auch der Betätigungsansatz 22 ist bezüglich der Gehäuseaußenfläche 25 versenkt angeordnet, während der angeformte Wulst 31 bezüglich der Gehäuseaußenfläche 28 geringfügig vorragt.The recess 15 is surrounded by outer surfaces 26, the recess 16 of outer surfaces 27 and the recess 17 of outer surfaces 28 of the blade housing 11. Like from the FIGS. 1 to 4 it is clear that these are Actuation approaches 20 and 21 and the molded beads 29 and 30 with respect to their surrounding housing outer surfaces 26 and 27 sunk arranged. Also, the actuating projection 22 is recessed with respect to the housing outer surface 25, while the molded bead 31 projects slightly with respect to the housing outer surface 28.

Es ist hervorzuheben, dass bei der Bedienung beispielsweise des Betätigungsansatzes 22 mit dem Daumen der rechten Hand die übrigen das Messergehäuse 11 umgreifenden Finger nicht mit den anderen Bedienansätzen 20 und 21 kollidieren, da die umgebenden Gehäuseaußenflächen 26 und 27 Finger- und Handanlageflächen bilden. Aufgrund der Gehäuseaußenflächen 26 und 27, welche Anlageflächen bilden, überspannt die Hand die Aussparungen 26 und 27 brückenartig und gerät nicht mit den Betätigungsansätzen 20 und 21 in Kontakt. Dieser vorteilhafte Effekt tritt ebenfalls bei Betätigung der Betätigungsansätze 20 oder 21 auf.It should be emphasized that in the operation of, for example, the actuating projection 22 with the thumb of the right hand, the rest of the blade housing 11 embracing fingers do not collide with the other Bedienansätzen 20 and 21, since the surrounding housing outer surfaces 26 and 27 finger and hand contact surfaces. Due to the housing outer surfaces 26 and 27, which form contact surfaces, the hand spans the recesses 26 and 27 like a bridge and does not come with the actuating lugs 20 and 21 in contact. This advantageous effect also occurs upon actuation of the actuating lugs 20 or 21.

Entgegen der Darstellung gemäß der Figuren 1 bis 4 kann auch der Wulst 31 bezüglich der Gehäuseaußenflächen 28 versenkt sein.Contrary to the representation according to the FIGS. 1 to 4 can also be the bead 31 with respect to the housing outer surfaces 28 sunk.
