Description

Die vorliegende Erfindung betrifft ein Hackmesser mit einem stauchgeschmiedetem Kröpf.The present invention relates to a cleaver with a compression-forged crimp.

Hackmesser mit einem stauchgeschmiedetem Kropf sind bekannt und setzen sich aus einem Messerblatt und/oder einer Messerklinge, einem Kropf und einem Griff zusammen, wobei der Griff mit dem Messerblatt und/oder einer Messerklinge über den Kropf miteinander verbunden ist. Auch sind Messer bekannt, bei denen die Klinge, der Kropf und der Erl durch Stauchschmiedung aus einem einzigen Rohling hergestellt werden.Chopping knives with a compression-forged goiter are known and are composed of a knife blade and / or a knife blade, a crop and a handle, wherein the handle is connected to the knife blade and / or a knife blade on the crop. Knives are also known in which the blade, the crop and the Erl are produced by compression forging from a single blank.

Die FR 2 612 432 A1 beschreibt beispielsweise ein Verfahren zur Herstellung eines aus mehreren Elementen bestehenden Hackmessers, bei dem ein Erl über einen stauchgeschmiedetem Kropf mit dem Messerblatt verbunden wird. Hingegen beschreibt die GB 692 042 A ein Verfahren zur Herstellung eines Messers, wobei der aus einem harten und rostfreien Material in einem Stück ausgestanzte Rohling zu einem Messer mit stauchgeschmiedetem Kropf verarbeitet wird.The FR 2 612 432 A1 describes, for example, a method for producing a multi-element cleaver in which a tang is connected to the knife blade via an upset goitre. On the other hand describes the GB 692 042 A a method for producing a knife, wherein the blank punched from a hard and stainless material in one piece is processed into a forge-forged knife.

Bei der Anwendung der bekannten Hackmesser kann es einen Kontakt zwischen den den Griff ergreifenden Fingern und der erlseitigen Messerblatt- und/oder Messerklingenfläche geben. Dadurch kann es zu unangenehmen Druckstellen an den Fingern kommen, weil die erlseitige Klingen- und/oder Blattfläche keine die Anatomie der Finger berücksichtigende Form aufweist.In the application of the known chopping knives, there may be contact between the gripping fingers and the erased knife blade and / or knife blade surface. This may cause unpleasant pressure points Fingers come because the erred blade and / or leaf surface does not have the anatomy of the finger taking into account.

Aus dem beschriebenen Nachteil ergibt sich für die vorliegende Erfindung die Aufgabe, ein Hackmesser zu schaffen, das eine bessere Handhabung und Habtik aufweist und somit eventuellen Verletzungen bei Nutzung des Hackmessers vorbeugt. Ferner ist es Aufgabe der Erfindung, bei einem guten Schutz der Finger eine optimale Nutzung der Schneide zu erreichen.From the described disadvantage results for the present invention, the task of creating a cleaver, which has better handling and Habtik and thus prevents possible injury when using the cleaver. It is another object of the invention to achieve optimal use of the blade with a good protection of the fingers.

Die Aufgabe wird durch die Merkmale des Gegenstandes von Anspruch 1 gelöst.The object is solved by the features of the subject of claim 1.

Der Vorteil dieser Erfindung ist, dass ein direkter Kontakt von Finger und Klinge und/oder Blatt vermieden wird und eine angenehmere Handhabung durch spezielle Ausgestaltungen des Kropfes gegeben wird.The advantage of this invention is that direct contact of the finger and blade and / or blade is avoided and more comfortable handling is provided by special designs of the crop.

Besonders vorteilhaft ist es, wenn der Kropf die hintere, dem Griff zugewandte Kante der Klingen- und/oder Blattfläche nur zu einem Teil bedeckt und der untere, an der Schneide endende Bereich der Kante vom Kropf unbedeckt ist. Hierdurch wird erreicht, dass zum einen die Finger vor der Klinge bzw. dem Blatt geschützt sind und zum anderen die Schneide über ihre gesamte Länge nutzbar ist. Auch noch das hintere Klingenende ist scharf und verwendbar. Hierbei ist von Vorteil, wenn der vom Kropf unbedeckte untere Bereich der Kante in seiner Höhe ½ bis 5/6 insbesondere 2/3 der Gesamthöhe des Blatts beträgt.It is particularly advantageous if the crop covers only a part of the rear edge of the blade and / or blade surface facing the handle, and the lower region of the edge ending at the cutting edge is uncovered by the crop. This ensures that, on the one hand, the fingers are protected from the blade or the blade and, on the other hand, the blade can be used over its entire length. Even the rear blade end is sharp and usable. It is advantageous if the bottom area of the edge uncovered by the crop is in its height ½ to 5/6, in particular 2/3 of the total height of the sheet.

Das erfindungsgemäße Hackmesser kann derart ausgebildet sein, dass die Klingen- und/oder Blattfläche im Umriss rechteckig, dreieckig, trapezförmig oder in Form einer unregelmäßigen Fläche ausgebildet ist, wobei die Schneide, der Rücken, die erlseitige Fläche und/oder die der erlseitigen Fläche an der Klinge und/oder dem Blatt gegenüberliegende Fläche eine kreisbogenförmige oder wellenförmige Form aufweisen können. Weiterhin kann die Klinge und/oder das Blatt eine konstante Dicke oder eine zur Schneide und/oder zum Rücken hin geringer und/oder größer werdende Dicke zwischen Rücken und Schneide aufweisen oder nach innen oder außen gewölbte Klingen- und/oder Blattflächen aufweisen oder zwei unterschiedlich geformte Klingen- und/oder Blattflächen aufweisen. Dazu können die Klingen und/oder Blattfläche eine Bohrung und/oder eine Nut aufweisen. Als Beispiele für die beschriebenen Formen gelten Cleaver, Chopper, beilartige Hackmesser, asiatische/chinesische Kochmesser oder dergleichen.The chopping knife according to the invention can be designed such that the blade and / or leaf surface in the outline is rectangular, triangular, trapezoidal or in the form of an irregular surface, wherein the cutting edge, the Back, the erler surface and / or the erlösseitigen surface on the blade and / or the sheet opposite surface may have a circular arc or wavy shape. Furthermore, the blade and / or the blade may have a constant thickness or a thickness between the back and the edge which is smaller and / or larger towards the cutting edge and / or may have inwardly or outwardly curved blade and / or leaf surfaces or two differently have shaped blade and / or leaf surfaces. For this purpose, the blades and / or leaf surface may have a bore and / or a groove. Examples of the shapes described are cleaver, chopper, casual cleaver, Asian / Chinese chef's knife or the like.

Nach einer vorteilhaften Ausgestaltung ist die zur axialen Richtung des Hackmessers senkrechte, zum Rücken des Hackmessers parallele Ausdehnung des Kropfes an zumindest einer Stelle breiter als die zum Rücken parallele Breite der erlseitigen Klingen- und/oder Blattfläche ausgebildet. Dadurch wird eine Fläche geschaffen, an die sich der zur Klinge und/oder zum Blatt nächstliegende Finger angenehm abstützen kann, so dass bei Verwendung des Hackmessers eine angenehme, kontrollierte und Druckstellen vermeidende Handhabung gewährleistet ist.According to an advantageous embodiment, the direction perpendicular to the axial direction of the cleaver, to the back of the cleaver parallel expansion of the crop at least one point is wider than the parallel to the back width of the liberated blade and / or leaf surface formed. As a result, an area is created, to which the finger closest to the blade and / or the blade can be comfortably supported, so that a pleasant, controlled and pressure points avoiding handling is ensured when using the cleaver.

Eine weitere Ausgestaltung der Erfindung sieht vor, dass der Kropf in seiner Ausdehnung zum Rücken des Hackmessers maximal so lang wie die Klinge und/oder das Blatt ausgebildet ist. Bei Hackmessern mit einem sehr großen Blatt ist es nicht notwendig, dass der Kropf über die gesamte erlseitige Blattfläche verläuft. Der Kropf ist jedoch so ausgebildet, dass er der angenehmen Handhabung des Hackmessers durch die Hand gerecht wird. Eine Ausführung des Kropfes länger als die Distanz zwischen Rücken und Schneide würde hingegen der Funktionsweise des Hackmessers im Wege stehen.A further embodiment of the invention provides that the crop is formed in its extension to the back of the chopping knife maximally as long as the blade and / or the blade. In the case of cleavers with a very large leaf, it is not necessary for the crop to run over the entire leaf area. However, the crop is designed to cope with the pleasant handling of the cleaver by hand. An execution of the crop longer than the distance between the back and cutting would, however, the functioning of the cleaver in the way.

Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht eine Ausformung am Kropf vor, die sich griffseitig zwischen Griff und Schneide befindet. Diese Ausformung dient einer angenehmen Führung des anliegenden Fingers, und bietet zusätzlich einen Schutz des Fingers vor Kontakt mit eventuell schneideseitig vorhandenem Material oder Gegenstand.A further advantageous embodiment of the invention provides a molding on the crop, which is located on the grip side between the handle and cutting edge. This shape is a pleasant guide of the adjacent finger, and additionally provides protection of the finger from contact with any cutting material or object.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung befindet sich am Kropf griffseitig zwischen Griff und Schneide eine Ausnehmung. Diese Ausnehmung dient ebenfalls einer angenehmen Führung des anliegenden Fingers, und bietet gleichzeitig einen Schutz des Fingers vor Kontakt mit eventuell schneideseitig vorhandenem Material oder Gegenstand.According to a further advantageous embodiment of the invention, there is a recess on the handle side between handle and cutting edge. This recess also serves a comfortable guidance of the adjacent finger, while providing protection of the finger from contact with any cutting side existing material or object.

Eine weitere Ausgestaltung des erfindungsgemäßen Kropfes sieht vor, dass der Kropf auf seiner der Klinge und/oder dem Blatt zugewandten Seite in Form einer zur erlseitigen Klingen- und/oder Blattfläche komplementären Fläche ausgebildet ist. Dadurch kann sich der Kropf zur Schaffung einer besseren Stabilität an der Klingen- und/oder Blattfläche abstützen, und steht einer einfachen Reinigung des Hackmessers nicht im Wege, da keine Absätze entstehen, in denen sich Verunreinigungen festsetzen könnten.A further embodiment of the bolster according to the invention provides that the bolster is formed on its side facing the blade and / or the blade in the form of a surface complementary to the extinct blade and / or blade surface. As a result, the crop can be supported on the blade and / or blade surface to provide better stability, and is not an obstacle to a simple cleaning of the cleaver, since no paragraphs arise in which impurities could accumulate.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist das Hackmesser aus einem in einem Stück aus einem rostfreien Material ausgestanzten Rohling durch einen Stauchschmiedeprozess hergestellt. Das ermöglicht eine Reduktion der zur Herstellung benötigten Arbeitsschritte und ist somit weniger kostenintensiv. Zudem wird dem Hackmesser dadurch eine hohe Stabilität gegeben, was dessen Lebensdauer erhöht. Es ist aber auch denkbar, dass das Hackmesser stattdessen aus mehreren Komponenten zusammengesetzt ist. Die Härte und Zusammensetzung des verwendeten Materials kann je nach Anforderung und Wunsch variieren.According to a further advantageous embodiment of the invention, the cleaver is made of a stamped in one piece from a stainless material blank by a compression forging process. This makes it possible to reduce the work steps required for the production and is thus less expensive. In addition, the cleaver is thereby given a high stability, which increases its life. But it is also conceivable that the cleaver is composed instead of several components. The hardness and composition of the material used can vary depending on the requirement and desire.

Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht vor, dass am Erl des Hackmessers Griffelemente angebracht sind. Diese werden mit dem Erl durch Vernietung oder Verklebung verbunden, und können aus Kunststoff, Keramik oder Metall bestehen.A further advantageous embodiment of the invention provides that gripping elements are attached to the Erl of the cleaver. These are connected to the Erl by riveting or gluing, and may be made of plastic, ceramic or metal.

Fig. 1 zeigt ein herkömmliches Hackmesser 1 in Seitenansicht, das aus der Klinge und/oder dem Blatt 2, dem Kropf 3 und dem Griff 4 besteht. Der Kropf 2 ist dabei ein Verbindungsglied von Klinge und/oder Blatt 2 und Griff 4, und weist in seinem Querschnitt die in Fig. 2 gezeigte Form auf. Bei Gebrauch dieses Hackmessers 1 kann es zu Kontakt eines Fingers mit der erlseitigen Fläche 5 der Klinge und/oder des Blatts 2 kommen. Diese Fläche 5 wird aber der Anatomie der Finger nicht gerecht, so dass das Hackmesser 1 eine unangenehme Handhabung aufweist. Fig. 1 shows a conventional chopping blade 1 in side view, which consists of the blade and / or the blade 2, the bolster 3 and the handle 4. The crop 2 is a link of blade and / or blade 2 and handle 4, and has in its cross section in Fig. 2 shown shape. When using this chopping blade 1, there may be contact of a finger with the recessed surface 5 of the blade and / or the blade 2. However, this surface 5 does not do justice to the anatomy of the fingers, so that the chopping blade 1 has an unpleasant handling.

Fig. 3 zeigt einen erfindungsgemäßen Kropf 6, der abweichend von der Querschnittsfläche der Klinge und/oder des Blatts 2 an einer Stelle 7 breiter ausgebildet ist als diese. Dadurch kann vermieden werden, dass es bei Gebrauch des Hackmessers zu unangenehmen Druckstellen am anliegenden Finger kommt, da der Finger an der breiteren Stelle 7 anliegt. Fig. 3 shows a crop according to the invention 6, the deviating from the cross-sectional area of the blade and / or the blade 2 at a location 7 is formed wider than this. This can help prevent it from happening Use of the cleaver to unpleasant pressure points on the adjacent finger comes because the finger rests on the broader point 7.

Eine weitere Ausbildung eines Hackmessers 8 ist in Fig. 4 dargestellt, die einen Kropf 6 zeigt, der griffseitig eine Ausformung 9 aufweist. Diese Ausformung 9 dient der sicheren Führung des Fingers bei Handhabung des Hackmessers 8, und gibt zugleich einen Schutz für den Finger, der in Kontakt mit auf der Arbeitsseite der Klinge und/oder des Blatts 2 befindlichen Gegenständen oder Materialien kommen könnte.Another embodiment of a cleaver 8 is in Fig. 4 shown, which shows a crop 6, the grip side has a formation 9. This formation 9 is used to safely guide the finger when handling the chopping blade 8, and at the same time gives a protection for the finger, which could come into contact with objects or materials located on the working side of the blade and / or the blade 2.

Fig. 5 zeigt ein weiteres Hackmesser 8 mit Kropf 6, bei dem unterhalb des Griffs 4 eine Ausnehmung 10 am Kropf 6 vorhanden ist, die eine sichere Führung eines Fingers ermöglicht, welcher gleichzeitig besser gegen Kontakt mit arbeitsseitig vorhandenen Gegenständen oder Materialien geschützt wird. Fig. 5 shows another cleaver 8 with crop 6, in which below the handle 4, a recess 10 on the bolster 6 is present, which allows a secure guidance of a finger, which is better protected at the same time against contact with working objects or materials existing.

Fig. 6 zeigt eine perspektivische Ansicht eines weiteren Hackmessers 8, bei dem links- und rechtsseitig des Erls 13 Griffelemente 14 angebracht sind, die in dieser Ausführung über Nieten 15 mit dem Erl 13 verbunden sind. Fig. 6 shows a perspective view of another chopping blade 8, in which left and right side of the Erls 13 gripping elements 14 are attached, which are connected in this embodiment via rivets 15 with the Erl 13.

Fig. 7 zeigt eine Seitenansicht eines erfindungsgemäßen Hackmessers, bei dem der Kropf 6 die hintere, dem Griff 4 zugewandte Kante 16 nicht über deren gesamte Höhe H bedeckt, sondern der untere Bereich 16a der Kante 16, der bis zur Schneide 11 führt und die Höhe h aufweist, ist vom Kropf 6 nicht bedeckt. Hierbei beträgt die Höhe h gleich ½ bis 5/6 insbesondere 2/3 der Höhe H. Auch ist von Vorteil, wenn die vordere Kante 17 des Kropfes, die auf der Seitenfläche des Blattes 2 liegt, derart schräg verläuft, dass das obere Ende 19 der Kante 17 näher zur vorderen Kante 20 des Blattes 2 liegt als das untere Ende 21 der Kante 17. Fig. 7 shows a side view of a chopping knife according to the invention, in which the crop 6, the rear, the handle 4 facing edge 16 is not covered over the entire height H, but the lower portion 16a of the edge 16, which leads to the cutting edge 11 and the height h, is not covered by goiter 6. Here, the height h is equal to ½ to 5/6, in particular 2/3 of the height H. Also, it is advantageous if the front edge 17 of the crop, which lies on the side surface of the sheet 2, is inclined so that the upper end of the 19th the edge 17 is closer to the front edge 20 of the sheet 2 than the lower end 21 of the edge 17th
