Offenbarung der ErfindungDisclosure of the invention

Die Aufgabe der Erfindung ist es, ein handgeführtes Messerwerkzeug mit einem Rundmesser zu schaffen, mit dem unterschiedliche Schnitttiefen möglich sind.The object of the invention is to provide a hand-held knife tool with a circular blade, with the different cutting depths are possible.

Die Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Günstige Ausgestaltungen und Vorteile der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und der Zeichnung.The object is solved by the features of claim 1. Favorable embodiments and advantages of the invention will become apparent from the other claims, the description and the drawings.

Es wird ein Messerwerkzeug vorgeschlagen, das ein Gehäuse aufweist, welches ein Rundmesser aufnimmt, wobei das Rundmesser entlang einer Hochachse des Gehäuses verschiebbar ist, und wobei das Rundmesser in Schneidstellung aus dem Gehäuse entsprechend einer durch Verschieben entlang der Hochachse eingestellten Schnitttiefe hervorsteht.It is proposed a knife tool having a housing which receives a circular blade, wherein the circular blade along a vertical axis of the housing is displaceable, and wherein the circular blade protrudes in the cutting position of the housing according to a set by moving along the vertical axis cutting depth.

Günstigerweise kann das Messerwerkzeug bequem und sicher mit einer Hand am Gehäuse gehalten werden, um eine Schnittbahn mit dem Rundmesser in Umverpackungen und dergleichen einzubringen. Vorteilhafterweise kann das Gehäuse so ausgebildet sein, dass nur ein kleiner Abschnitt des Zahnkranzes des Rundmessers nach außen ragt und der größte Teil des Zahnkranzes im Gehäuse angeordnet ist. Das Gehäuse kann in etwa eine C-Form aufweisen und das Rundmesser zum Gebrauch in der Mitte der C-Form herausragen. Vorteilhaft kann am Messerwerkzeug in dem Bereich, in dem das Rundmesser hervorsteht, wenigstens eine Gleitfläche vorgesehen sein. Vorteilhaft kann auf beiden Seiten des Bereichs eine Gleitfläche vorgesehen sein. Mittels einer oder mehrerer Gleitflächen kann das Messerwerkzeug zuverlässig über einen Untergrund geführt werden, um Schnittbahnen zu erzeugen. Die Gleitflächen können am Gehäuse angeordnet sein.Conveniently, the knife tool can be conveniently and safely held with one hand on the housing to introduce a cutting path with the circular blade in outer packaging and the like. Advantageously, the housing may be formed so that only a small portion of the ring gear of the circular blade protrudes outward and the largest part of the ring gear is arranged in the housing. The housing may be approximately C-shaped and the circular blade may protrude into the middle of the C-shape for use. Advantageously, at least one sliding surface can be provided on the knife tool in the region in which the circular blade protrudes. Advantageously, a sliding surface can be provided on both sides of the area. By means of one or more sliding surfaces, the knife tool can be reliably guided over a substrate to produce cutting paths. The sliding surfaces can be arranged on the housing.

Alternativ können eine oder mehrere Gleitflächen am Gehäuse befestigt und im Abstand zum Gehäuse veränderbar sein. Die Schnitttiefenverstellung kann dann über die Einstellung des Abstands der Gleitfläche(n) zum Gehäuse vorgenommen werden, während das Rundmesser selbst bezüglich seiner Höhe im Gehäuse unveränderlich sein kann.Alternatively, one or more sliding surfaces can be fixed to the housing and be variable at a distance from the housing. The cutting depth adjustment can then be made by adjusting the distance of the sliding surface (s) to the housing, while the circular blade itself can be fixed with respect to its height in the housing.

Vorteilhaft kann zwischen zwei Gleitflächen am Gehäuseboden eine Aussparung für das Rundmesser vorgesehen sein. In der Aussparung ist die Position des Messers erkennbar, auch wenn das Rundmesser nicht aus dem Gehäuse herausragt.Advantageously, a recess for the circular blade can be provided between two sliding surfaces on the housing bottom. In the recess, the position of the knife is recognizable, even if the circular blade does not protrude from the housing.

Gemäß einer günstigen Ausgestaltung kann das Gehäuse aus zwei Halbschalen gebildet sein, zwischen denen das Rundmesser drehbar gelagert ist. Dies ermöglicht eine sichere Montage des Rundmessers im Gehäuse und schützt den Verstellmechanismus zur Verstellung der Schnitttiefe. Alternativ kann das Gehäuse auch mit nur einer Schale ausgebildet sein. Vorteilhaft kann das Rundmesser zwischen den der jeweiligen Halbschalen zugeordneten Klemmteilen geklemmt und mit diesen drehbar gelagert sein.According to a favorable embodiment, the housing may be formed of two half-shells, between which the circular blade is rotatably mounted. This allows a safe mounting of the circular blade in the housing and protects the adjustment mechanism for adjusting the depth of cut. Alternatively, the housing may also be formed with only one shell. Advantageously, the circular blade can be clamped between the clamping parts associated with the respective half-shells and rotatably mounted therewith.

Gemäß einer günstigen Ausgestaltung kann das Rundmesser an einem Schlitten angeordnet sein, der bei einer vorgegebenen Schnitttiefe fixierbar ist. Der Schlitten kann beispielsweise festklemmbar sein. Der Schlitten kann manuell verschoben werden, wenn eine Klemmkraft gelöst ist und sicher fixiert werden, wenn die Klemmkraft entsprechend erhöht wird.According to a favorable embodiment, the circular blade can be arranged on a carriage which can be fixed at a predetermined cutting depth. The carriage may for example be clamped. The carriage can be moved manually when a clamping force is released and securely fixed when the clamping force is increased accordingly.

Der Schlitten kann in der Aussparung führbar sein.The carriage may be feasible in the recess.

Der Schlitten kann an zwei parallel zur Hochachse angeordneten Stäben befestigt sein. Vorteilhaft kann zur Fixierung des Schlittens eine Zugstange vorgesehen sein, die mit einer quer zur Längserstreckung der Zugstange angeordneten Klemmwelle verbunden ist, die zur Fixierung an die Stäbe anlegbar ist. Damit ist eine zuverlässige Festlegung der Position bezüglich der Hochachse und damit der Schnitttiefe des Rundmessers möglich. Durch Lösen der Klemmwelle kann die Position verändert werden. Die Zugstange kann hierzu beispielsweise mit einer Rändelschraube versehen sein, die zum Fixieren festgedreht und zum Lösen aufgedreht werden kann.The carriage can be attached to two rods arranged parallel to the vertical axis. Advantageously, a pull rod can be provided for fixing the carriage, which is connected to a transversely arranged to the longitudinal extension of the drawbar clamping shaft, for fixing to the rods can be applied. For a reliable determination of the position with respect to the vertical axis and thus the depth of cut of the circular blade is possible. By loosening the clamping shaft, the position can be changed. For this purpose, the drawbar can be provided, for example, with a knurled screw which can be tightened for fixing and unscrewed for loosening.

Alternativ kann eine Verschiebung des Schlittens auch über einen Servoantrieb erfolgen, mit dem der Schlitten direkt bewegt und auch fixiert werden kann.Alternatively, a displacement of the carriage can also take place via a servo drive, with which the carriage can be moved directly and also fixed.

Zur reproduzierbaren Einstellung der Schnitttiefe kann eine entsprechende Skala am Gehäuse oder an einer sonstigen geeigneten Stelle vorgesehen sein.For reproducible adjustment of the depth of cut, a corresponding scale can be provided on the housing or at another suitable location.

Das Messerwerkzeug ist für Rundmesser geeignet, die einen Zahnkranz mit Schneiden aufweisen, mit denen Perforierschnitte ausgeführt werden können. Das Messerwerkzeug ist jedoch auch für den Einsatz von Rundmessern mit glattem Rand geeignet.The knife tool is suitable for circular blades, which have a ring gear with cutting, with which perforating cuts can be performed. However, the knife tool is also suitable for the use of circular knives with a smooth edge.

Denkbar ist das Messerwerkzeug 100 jedoch auch in Kombination mit einem Rundmesser mit glatter Schneide.In the FIGS. 1 to 4 an embodiment of a knife tool 100 is shown with a disc-shaped circular blade 10 with adjustable depth of cut according to the invention. It is a toothed circular blade 10 shown, with which a perforating cut can be performed. However, the knife tool 100 is also conceivable in combination with a circular blade with a smooth cutting edge.

Figur 1 zeigt das Messerwerkzeug 10 in einer Seitenansicht. Das Gehäuse umgibt den größten Teil des Rundmessers 10 und ist im Ausführungsbeispiel in etwa C-förmig ausgebildet. Das Messerwerkzeug 10 in Figur 1 ist symmetrisch zur Zeichenebene aufgebaut. Das Rundmesser 10 ist zwischen zwei Halbschalen 102 angeordnet und parallel zu deren Flachseiten ausgerichtet. Die beiden Halbschalen 102 bilden im zusammengesetzten Zustand ein flaches, beispielsweise rechteckiges, Gehäuse 150, das bequem und sicher in der Hand gehalten werden kann. Andere Gehäuseformen sind ebenso denkbar. Im zusammengesetzten Zustand sind die Halbschalen 102 mit zwei Schrauben 116, z.B. Zylinderschrauben, verschraubt. FIG. 1 shows the knife tool 10 in a side view. The housing surrounds most of the circular blade 10 and is formed in the embodiment in an approximately C-shaped. The knife tool 10 in FIG. 1 is symmetrical to the drawing plane. The circular blade 10 is arranged between two half-shells 102 and aligned parallel to their flat sides. The two half-shells 102 form a flat, for example rectangular, housing 150 in the assembled state, which can be comfortably and securely held in the hand. Other types of housing are also conceivable. In the assembled state, the half-shells 102 are screwed with two screws 116, for example cylinder screws.

In den Halbschalen 102, von denen nur die vordere in der Figur zu sehen ist, kann das Rundmesser 10 entlang der Hochachse A der Halbschalen 102, verschoben werden, um die Schnitttiefe des Rundmessers 10 einzustellen. Die Schnitttiefe entspricht dem Überstand des Rundmessers 10 über den Gehäuseboden hinaus, insbesondere dem Überstand über am Gehäuseboden angeordnete Gleitflächen 126, 128.In the half-shells 102, of which only the front one can be seen in the figure, the circular blade 10 can be displaced along the vertical axis A of the half-shells 102, in order to adjust the cutting depth of the circular blade 10. The depth of cut corresponds to the projection of the circular blade 10 beyond the housing bottom, in particular the projection via sliding surfaces 126, 128 arranged on the housing bottom.

In Figur 1 ist das Rundmesser 10 in einer Schneidposition dargestellt, die der geringsten Schnitttiefe entspricht, bei der es nur geringfügig über den Gehäuseboden bzw. den Boden der Halbschalen 102 hinausragt. Im Nichtgebrauchszustand kann das Rundmesser 10 zur Vermeidung einer Verletzungsgefahr für einen Benutzer auch in das Gehäuse 150 eintauchen, so dass die Schneide nicht über den Gehäuseboden des Gehäuses 150 übersteht. In den Halbschalen 102 ist zwischen zwei Gleitflächen 126, 128 eine Aussparung 122 vorgesehen, in der das Rundmesser 10, in der Zeichenebene gesehen, nach oben oder unten verschoben werden kann, so dass das Rundmesser 10 mehr oder weniger über die Gleitflächen 126, 128 am Gehäuseboden übersteht. Im Nichtgebrauchszustand kann das Rundmesser 10 zur Verringerung einer Verletzungsgefahr vollständig in das Gehäuse 150 eintauchen. Der Boden der Halbschalen 102 ist zu beiden Seiten der Aussparung 122 jeweils als Gleitfläche 126, 128 ausgebildet. Mit den Gleitflächen 126, 128 kann das Messerwerkzeug 100 auf einen zu schneidenden oder zu perforierenden Untergrund, z.B. einen Karton, aufgesetzt werden und entlang einer gewünschten Schnittbahn geschoben oder gezogen werden, während das Rundmesser 10 auf dem Untergrund abrollt. Dazu ist das Rundmesser in zwei Klemmteilen 110 (nur eines ist in der Figur zu erkennen) eingeklemmt, und mit diesen drehbar gelagert.In FIG. 1 the circular blade 10 is shown in a cutting position, which corresponds to the lowest depth of cut, at which it protrudes only slightly beyond the housing bottom and the bottom of the half-shells 102. In the non-use state, the circular blade 10 can also be immersed in the housing 150 so as to avoid a risk of injury to a user, so that the cutting edge does not protrude beyond the housing bottom of the housing 150. In the half-shells 102, a recess 122 is provided between two sliding surfaces 126, 128, in which the circular blade 10, seen in the plane, can be moved up or down, so that the circular blade 10 more or less on the sliding surfaces 126, 128 on Caseback protrudes. When not in use, the circular blade 10 can be completely immersed in the housing 150 to reduce the risk of injury. The bottom of the half-shells 102 is formed on both sides of the recess 122 in each case as a sliding surface 126, 128. With the sliding surfaces 126, 128, the knife tool 100 can be placed on a substrate to be cut or perforated, for example a cardboard, and pushed or pulled along a desired cutting path while the circular blade 10 rolls on the ground. For this purpose, the circular blade is clamped in two clamping parts 110 (only one can be seen in the figure), and rotatably mounted therewith.

Zur Verstellung der Schnitttiefe kann das Rundmesser 10 mit einem Schlitten 104 entlang der Hochachse A verschoben werden. Hierzu ist ein Mechanismus vorgesehen, dessen Details in den weiteren Figuren erläutert sind. Von außen ist z.B. eine Rändelmutter 130 zu bedienen, die eine Klemmwelle 108 fixiert, wenn eine Schnitttiefe eingestellt ist, und die gelöst werden kann, um den Schlitten 104 zu verschieben.To adjust the depth of cut, the circular blade 10 can be moved with a carriage 104 along the vertical axis A. For this purpose, a mechanism is provided, whose details are explained in the other figures. From the outside is e.g. To operate a knurled nut 130, which fixes a clamping shaft 108 when a depth of cut is set, and which can be solved to move the carriage 104.

Figur 2 zeigt einen Schnitt durch die Mitte des Messerwerkzeugs 100 aus Figur 1. Das Messerwerkzeug 100 ist spiegelsymmetrisch zur Hochachse A aufgebaut. Der Übersichtlichkeit wegen ist nur eine Seite des Gehäuses mit einer Halbschale 102 des Gehäuses 150 mit Bezugszeichen beziffert. FIG. 2 shows a section through the center of the knife tool 100 from FIG. 1 , The knife tool 100 is constructed mirror-symmetrically to the vertical axis A. For the sake of clarity, only one side of the housing with a half-shell 102 of the housing 150 is numbered with reference numerals.

Das Rundmesser 10 ist mit seinen Flachseiten zwischen zwei Klemmteilen 110 eingeklemmt, die drehbar in einem Schlitten 104 gelagert sind, damit das Rundmesser 10 auf einem Untergrund abrollen kann, wenn es über die Gleitflächen 126, 128 (Figur 1) hinaussteht.The circular blade 10 is clamped with its flat sides between two clamping parts 110, which are rotatably mounted in a carriage 104, so that the circular blade 10 can roll on a substrate when it passes over the sliding surfaces 126, 128 (FIG. FIG. 1 ) stands out.

Jedes der Klemmteile 110 ist, z.B. mittels Schrauben 114, an einem Stab 106 befestigt, der parallel zur Hochachse A angeordnet ist und entlang seiner Längsachse (Hochachse A) verschiebbar ist. Die beiden Klemmteile 110 sind mit einem Gewindestift 118 verbunden, der durch eine zentrale Öffnung im Rundmesser 10 durchgeführt ist.Each of the clamping parts 110 is, e.g. by means of screws 114, attached to a rod 106 which is arranged parallel to the vertical axis A and along its longitudinal axis (vertical axis A) is displaceable. The two clamping parts 110 are connected to a threaded pin 118, which is performed by a central opening in the circular blade 10.

Figur 3 zeigt in isometrischer Darstellung eine Halbschale 102 des Gehäuses 150 mit entfernter zweiter Halbschale des Messerwerkzeugs 10 aus Figur 1. Zur Positionierung der beiden Halbschalen 102 beim Zusammenbau ist benachbart zu jeder der Schrauben 116, mit denen die Halbschalen 102 verbunden werden, jeweils ein Zylinderstift 120 vorgesehen. FIG. 3 shows in isometric view a half shell 102 of the housing 150 with the second half shell of the knife tool 10 removed FIG. 1 , to Positioning of the two half-shells 102 during assembly is provided adjacent each of the screws 116 to which the half shells 102 are connected, one cylindrical pin 120 each.

Benachbart zur Aussparung 122 in den Halbschalen 102 ist eine Stufe in den Halbschalen 102 als Freiraum für das Rundmesser 10 bei der Schnitttiefenverstellung entlang der Hochachse A vorgesehen. Das Klemmteil 110 bzw. der Schlitten 104 ist in der Aussparung 122 geführt.Adjacent to the recess 122 in the half-shells 102, a step in the half-shells 102 is provided as clearance for the rotary blade 10 in the cutting depth adjustment along the vertical axis A. The clamping part 110 or the carriage 104 is guided in the recess 122.

Die Rändelmutter 130 ist über eine Zugstange 112 mit einer Klemmwelle 108 verbunden. Die Zugstange 112 kann mit der Klemmwelle 108 verschraubt sein. Bei Bedarf kann ein Gewinde 113 in die Klemmwelle eingelassen, z.B. eingeklebt, sein. Die Zugstange 112 kann jedoch mit der Klemmwelle 108 auch direkt verklebt oder verschweißt sein.The knurled nut 130 is connected via a pull rod 112 with a clamping shaft 108. The pull rod 112 may be bolted to the clamp shaft 108. If necessary, a thread 113 may be inserted in the clamping shaft, e.g. glued, be. However, the pull rod 112 may also be directly glued or welded to the clamping shaft 108.

Ist die Rändelmutter 130 festgezogen, wird die Klemmwelle 108 fest gegen die Stäbe 106 in den Halbschalen 102 gepresst und fixiert diese und somit den Schlitten 104, der das Rundmesser 10 trägt, in der Höhe.If the knurled nut 130 is tightened, the clamping shaft 108 is pressed firmly against the rods 106 in the half-shells 102 and fixes them and thus the carriage 104, which carries the circular blade 10, in height.

Figur 4 ist ein Querschnitt durch das Messerwerkzeug 100 aus Figur 1 entlang der Linie IV-IV dargestellt, in dem die Verbindung der Rändelmutter 130 und der Zugstange 112 mit der Klemmwelle 108 und das Zusammenwirken der Klemmwelle 108 mit den Stäben 106 in den Halbschalen 102 zu erkennen ist. Die Klemmwelle 108 liegt an beiden Stäben 106 der Schlitten 104 in den Halbschalen 102 an, wenn die Rändelmutter 130 festgezogen ist. Die Klemmwelle 108 weist formkomplementäre Aussparungen 109 auf, damit die Klemmwelle 108 eine möglichst große Kontaktfläche mit den Stäben 106 aufweist, was die Haltekraft der Klemmwelle 108 verbessert. FIG. 4 is a cross section through the knife tool 100 from FIG. 1 along the line IV-IV, in which the connection of the knurled nut 130 and the tie rod 112 with the clamping shaft 108 and the interaction of the clamping shaft 108 with the rods 106 in the half-shells 102 can be seen. The clamping shaft 108 abuts both rods 106 of the carriages 104 in the half-shells 102 when the knurled nut 130 is tightened. The clamping shaft 108 has form-complementary recesses 109, so that the clamping shaft 108 has the largest possible contact surface with the rods 106, which improves the holding force of the clamping shaft 108.
