Description

Die Erfindung betrifft ein Abenteuermesser oder dergleichen mit den Merkmalen des Oberbegriffes des Patentanspruches 1. Die Erfindung ist aber in gleicher Weise für Messer anwendbar, die zu Jagdzwecken oder für militärische Zwecke geeignet sind, beispielsweise für Jagdmesser oder Bajonetts bzw. Seitengewehre.The invention relates to an adventure knife or the like with the features of the preamble of claim 1. However, the invention can be used in the same way for knives that are suitable for hunting purposes or for military purposes, for example for hunting knives or bayonets or side guns.

Bei Messern dieser Art besteht das Bedürfnis, die Schneide der Klinge von Zeit zu Zeit nachzuschleifen, um die Funktionsfähigkeit des Messers aufrechterhalten zu können.Knives of this type have to be re-sharpened from time to time in order to maintain the functionality of the knife.

Zu diesem Zweck ist es bekannt, das Abenteuermesser oder dergleichen mit einem Schleifstein auszurüsten, der in einer an bzw. auf der Schneide angebrachten Aufnahme steckt und bei Bedarf herausgenommen werden kann. Da der Schleifstein jedoch ein separates Teil ist, kann er bei oder nach Benutzung herabfallen, falsch abgelegt werden oder einfach verloren gehen, so daß nicht gewährleistet ist, daß die Schneide der Klinge des Messers bei Bedarf stets nachgeschliffen werden kann, selbst wenn keine speziellen Werkzeuge oder sonstige Hilfsmittel zur Verfügung stehen.For this purpose, it is known to equip the adventure knife or the like with a grindstone which is in a receptacle attached to or on the cutting edge and can be removed if necessary. However, since the sharpening stone is a separate part, it can fall off during or after use, be put down incorrectly or simply get lost, so that it is not guaranteed that the cutting edge of the blade of the knife can always be re-sharpened if necessary, even if no special tools are used or other aids are available.

Hinzu kommt, daß die Benutzung eines in einem an der Scheide des Messers vorgesehenen Behältnis untergebrachten separaten Schleifsteines umständlich und umbequem ist, denn zum Schleifen muß der Schleifstein aus dem mit einer Klappe veschlossenen Behältnis herausgenommen und von Hand über die Schneide der Klinge geführt werden. Da der Schleifstein verhältnismäßig klein ist, kann er nur mit Mühe gehalten werden. Deshalb unterbleibt bei derart ausgerüsteten Abenteuermessern oder dergleichen vielfach das notwendige Nachschleifen der Klinge, so daß die Klinge oftmals trotz der vorhandenen Nachschleifmöglichkeit stumpf ist.In addition, the use of a separate grindstone housed in a container provided on the sheath of the knife is cumbersome and uncomfortable because the grindstone has to be removed from the flap with a flap closed container and taken out by hand over the cutting edge of the blade. Since the grindstone is relatively small, it can only be held with difficulty. Therefore, in the case of adventure knives or the like equipped in this way, the necessary regrinding of the blade is often omitted, so that the blade is often blunt in spite of the existing regrinding possibility.

Bei einem bekannten Messer (DE-B-1 274 476) ist als Schleifeinrichtung auf der Außenseite der Scheide ein Schleifstein dauerhaft angeordnet. Sowohl bei den dauerhaft an der Scheide angeordneten als auch bei den zuvor beschriebenen lediglich dem Messer beigefügten Schleifsteinen kommt es dazu, daß sich in den offenen Poren dieser Schleifsteine mit der Zeit Schmutz und Fette absetzen können, welche die Poren schließen, wodurch die Schleiffähigkeit und Schleifleistung deutlich verringert werden.In a known knife (DE-B-1 274 476), a grinding stone is permanently arranged on the outside of the sheath as a grinding device. Both in the permanently arranged on the sheath and in the previously described grinding stones only added to the knife, it happens that in the open pores of these grinding stones, dirt and grease can settle over time, which close the pores, thereby reducing the grinding ability and grinding performance be significantly reduced.

Bei einem weiteren bekannten Messer (US-A-4 326 652) ist eine Schleifplatte beschrieben, die an einem Träger, durch den ein Gürtel gesteckt werden kann, befestigt ist und die aus einem material mit eingebetteten Diamanten bestehen kann. Dabei hat es sich jedoch gezeigt, daß ein Schärfen des Messers umständlich und unbequem ist, weil der Schleifstein bzw. die Schleifplatte wiederum klein ist und kein gesonderter Handgriff zum Halten der Schleifplatte vorgesehen ist, so daß zusätzlich noch eine Verletzungsgefahr auftritt.Another known knife (US-A-4 326 652) describes a grinding plate which is fastened to a carrier through which a belt can be inserted and which can consist of a material with embedded diamonds. However, it has been shown that sharpening the knife is cumbersome and uncomfortable because the grindstone or grinding plate is again small and there is no separate handle for holding the grinding plate, so that there is also a risk of injury.

Der Erfindung liegt die Aufgabe zugrunde, ein Abenteuermesser oder dergleichen zu schaffen, das eine preiswerte, einfach zu handhabende und zuverlässig bzw. dauerhaft wirksame Schleifeinrichtung zum Nachschleifen der Schneide der Messerklinge aufweist.The invention has for its object to provide an adventure knife or the like which has an inexpensive, easy-to-use and reliable or permanently effective grinding device for regrinding the cutting edge of the knife blade.

Diese Aufgabe wird bei einem Abenteuermesser oder dergleichen der eingangs genannten Gattung mit den Merkmalen des kennzeichnenden Teiles des Patentanspruches 1 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.This task is in an adventure knife or the like of the type mentioned with the features of characterizing part of claim 1 solved. Further advantageous embodiments of the invention are the subject of the dependent claims.

Der Benutzer des Abenteuermessers oder dergleichen kann nun die Scheide der Messerklinge schnell und effektiv nachschleifen, weil ein guter und wirksamer Kontakt zwischen Schleifmittelschicht und der nachzuschleifenden Klinge gewährleistet ist. Die Schleifmittelschicht ist an einem Ende der Scheide angebracht, so daß für den Schleifvorgang die Scheide einem Handgriff mit verhältnismäßig langem Hebelarm entspricht.The user of the adventure knife or the like can now sharpen the sheath of the knife blade quickly and effectively because good and effective contact between the abrasive layer and the blade to be sharpened is ensured. The abrasive layer is attached to one end of the sheath, so that the sheath corresponds to a handle with a relatively long lever arm for the grinding process.

Hinzu kommt, daß die erfindungsgemäß vorzusehende Schleifmittelschicht kaum über die Oberfläche der Scheide des Abenteuermessers oder dergleichen ragt und somit bei normalem Gebrauch bzw. bei normalem Tragen des Messers nicht stört. Im Gegensatz zu einem Poren enthaltenden Schleifstein hat eine erfindungsgemäß vorzusehende Schleifmittelschicht den Vorteil, daß sie keine Poren oder ähnliche Öffnungen enthält, welche sich mit Körperfetten, Schmutz oder Verunreinigungen zu setzen können, so daß die Schleifwirkung der erfindungsgemäß vorzusehenden Schleifeinrichtung auch im rauhen Feldbetrieb, wo Schmutz- und Schlammeinwirkungen nicht zu vermeiden sind, nicht beeinträchtigt werden kann.In addition, the abrasive layer to be provided according to the invention hardly protrudes over the surface of the scabbard of the adventure knife or the like and thus does not interfere with normal use or with normal wearing of the knife. In contrast to a pore-containing grindstone, an abrasive layer to be provided according to the invention has the advantage that it does not contain any pores or similar openings, which can settle with body fat, dirt or impurities, so that the grinding action of the grinding device to be provided according to the invention also in rough field operation, where The effects of dirt and sludge cannot be avoided and cannot be impaired.

Desweiteren ist es auf diese Weise möglich, die Schleifeinrichtung dauerhaft mit der Scheide auf einfache und preiswerte Weise zu verbinden. Dabei ist ein absatzloser Übergang in die Oberfläche der Scheide möglich, d. h. es entstehen keine scharfen Kanten oder Übergänge, die zum Abreißen oder Abbrechen der Schleifmittelbeschichtung führen könnten.Furthermore, it is possible in this way to permanently connect the grinding device to the sheath in a simple and inexpensive manner. Here is a paragraphless Transition into the surface of the scabbard possible, ie there are no sharp edges or transitions that could lead to tearing or breaking of the abrasive coating.

Die Schleifmittelschicht kann erfindungsgemäß an der Innenseite der Scheide vorgesehen sein kann, weil sie dann normalerweise am Körper des Trägers des Abenteuermessers oder dergleichen anliegt und somit Umwelteinflüssen und insbesondere dem Einfluß von Schmutz wenig ausgesetzt ist.According to the invention, the abrasive layer can be provided on the inside of the scabbard, because it then normally rests on the body of the wearer of the adventure knife or the like and is therefore little exposed to environmental influences and in particular the influence of dirt.

Ein weiterer Vorteil der Erfindung liegt darin, daß als Schleifmaterial Kristalle bzw. Kristallsplitter aus Korund Saphir und/oder Diamant verwendet werden, die in einer Trägerschicht, beispielsweise aus Nickel, verankert sind. Dementsprechend sind keine Poren vorgesehen, die sich durch Fett oder sonstigen Schmutz zusetzen können.Another advantage of the invention is that crystals or crystal splinters made of corundum sapphire and / or diamond are used as the grinding material, which are anchored in a carrier layer, for example made of nickel. Accordingly, there are no pores that can become clogged by grease or other dirt.

Die Kristallsplitter bzw. Kristallkörper können zwar durch Benutzung oder aufgrund sonstiger Verschleißerscheinungen abbrechen, jedoch entstehen dabei stets neue Kanten und/oder Spitzen, die die gewünschte Schleifwirkung aufweisen. Eventuell sich zwischen die einzelnen Kristalle oder Kristallsplitter bzw. Schleifkörperteile setzende Schmutzpartikel bleiben dort nicht dauerhaft haften und stören insbesondere nicht die Schleifwirkung der Schleifkörper.The crystal splinters or crystal bodies can break off due to use or due to other signs of wear, but new edges and / or tips are always created which have the desired grinding effect. Any dirt particles that may settle between the individual crystals or crystal splinters or grinding wheel parts do not remain there permanently and in particular do not interfere with the grinding action of the grinding wheel.

Durch die Erfindung wird ein Abenteuermesser oder ein für jagdliche oder militärische Zwecke geeignetes Messer geschaffen, das mit einer sehr einfach ausgebildeten, jedoch äußerst wirkungsvollen und dauerhaften Schleifeinrichtung ausgestattet ist, so daß die Schneide des Messers jederzeit einfach und wirkungsvoll nachgeschliffen bzw. geschärft werden kann. Zu diesem Zweck ist es lediglich erforderlich, das Messer in die eine Hand und die Scheide in die andere Hand zu nehmen und zum Schärfen die Schneide über die Schleifmittelbeschichtung zu führen. Beide Teile, nämlich Messer und Scheide, bilden einen verhältnismäßig langen Hebelarm zu den miteinander zusammenwirkenden Abschnitten, nämlich der Klinge und der Schleifmittelbeschichtung, so daß das Nachschleifen bzw. Schärfen der Schneidekraft voll und somit wirkungsvoll ausgeführt werden kann.The invention provides an adventure knife or a knife suitable for hunting or military purposes, which is equipped with a very simple, but extremely effective and durable grinding device, so that the cutting edge of the knife can be sharpened or sharpened easily and effectively at any time. For this purpose it is only necessary to take the knife in one hand and the sheath in the other hand and to sharpen the cutting edge over the To carry out abrasive coating. Both parts, namely knife and sheath, form a relatively long lever arm to the interacting sections, namely the blade and the abrasive coating, so that the regrinding or sharpening of the cutting force can be carried out fully and thus effectively.

In der Zeichnung ist ein Ausführungsbeispiel eines erfindungsgemaß ausgestalteten Abenteuermessers oder auch Seitengewehrs dargestellt, und zwar zeigt

Figur 1
eine Ansicht der Rückseite des Abenteuermessers, das heißt also der Seite, die am Körper getragen wird, und
Figur 2
einen Querschnitt der Scheide des Abenteuermessers nach Linie II - II aus Figur 1, wobei die auf der Rückseite der Scheide angebrachte Schleifmittelschicht zur besseren Erkennbarkeit übertrieben groß bzw. dick dargestellt ist.
In the drawing, an embodiment of an inventive adventure knife or side rifle is shown, and shows
Figure 1
a view of the back of the adventure knife, that is, the side that is worn on the body, and
Figure 2
a cross-section of the scabbard of the adventure knife according to line II - II of Figure 1, wherein the abrasive layer attached to the back of the scabbard is shown exaggeratedly large or thick for better visibility.

Das Abenteuermesser (1) besteht im wesentlichen aus dem eigentlichen messer (2) und einer Scheide (3), in deren innere Öffnung (4)die Klinge (5) des Messers (2) eingesteckt werden kann, während der Handgriff (6) außerhalb der Scheide (3) verbleibt und sich das Heft bei eingestecktem Messer (2) als eine Art Anschlag auf die Oberseite der Scheide (3)legt.The adventure knife (1) consists essentially of the actual knife (2) and a sheath (3), in the inner opening (4) of which the blade (5) of the knife (2) can be inserted, while the handle (6) outside the scabbard (3) remains and when the knife (2) is inserted, the booklet lies as a kind of stop on the top of the scabbard (3).

An der Rückseite der Scheide (3)ist am oberen Ende eine Halterung (8) angebracht, mit der die Scheide (3)beispielsweise an einen Gürtel angebracht werden kann, um das Abenteuermesser (1)am Körper eines Benutzers tragen zu können.On the back of the scabbard (3), a holder (8) is attached at the upper end, with which the scabbard (3) can be attached to a belt, for example, in order to be able to carry the adventure knife (1) on a user's body.

Am oberen Ende der Scheide (3)befindet sich auf der Rückseite derselben in einer begrenzten Zone (9)eine streifenförmige Schleifmittelschicht (10), die aus einem unmittelbar auf der Scheide angebrachten Einbettmedium (11) und in diese eingebetteten Schleifkörner (12), beispielsweise Kristalle oder Kristallsplitter, gebildet ist.At the upper end of the sheath (3) there is a strip-shaped abrasive layer (10) on the back of the sheath in a limited zone (9), which consists of an embedding medium (11) directly attached to the sheath and abrasive grains (12) embedded therein, for example Crystals or crystal splinters is formed.

Die Schleifmittelschicht (10) ist am oberen Ende und auf der Rückseite der Scheide (3) angebracht. Will man die Schneide der Klinge (5) des Messers (2) nachschleifen oder anschärfen, nimmt man das Messer (2) am Handgriff (6) in die eine Hand und die Scheide (3) in die andere Hand, zieht das Messer (2) aus der Scheide heraus und führt die Schneide der Klinge (5) über die Schleifmittelschicht (10). Sowohl das Messer (2) als auch die Scheide (3) können bequem gehalten werden, ohne daß die Hände in den Bereich der Schleifmittelschicht (10) bzw. der anzuschärfenden Klinge (5) kommen können. Somit sind nicht nur günstige Hebelarme für ein kraftvolles Nachschleifen bzw. Anschärfen der Klinge gegeben, sondern es besteht auch keine Verletzungsgefahr, weil der Benutzer die Schleifeinrichtung nicht unmittelbar anfassen muß.The abrasive layer (10) is attached to the upper end and on the back of the sheath (3). Do you want the edge of the blade (5) Regrinding or sharpening the knife (2), take the knife (2) by the handle (6) in one hand and the sheath (3) in the other hand, pull the knife (2) out of the sheath and guide the cutting edge the blade (5) over the abrasive layer (10). Both the knife (2) and the sheath (3) can be held comfortably without the hands being able to get into the area of the abrasive layer (10) or the blade (5) to be sharpened. Thus, not only are there favorable lever arms for powerful regrinding or sharpening of the blade, but there is also no risk of injury because the user does not have to touch the grinding device directly.

Die Schleifmittelschicht (10) enthält keine Poren oder sonstige Öffnungen, in welchen sich Schmutz oder sonstige Verunreinigungen festsetzen und dadurch die Schleifkörner unwirksam machen können. Die Schleifkörner (12) sind zweckmäßig Kristalle oder Kristallsplitter, die aus Korund, Saphir, Diamant oder Mischungen dieser Kristallarten bestehen können.The abrasive layer (10) does not contain any pores or other openings in which dirt or other impurities settle and can thereby render the abrasive grains ineffective. The abrasive grains (12) are expediently crystals or crystal chips, which can consist of corundum, sapphire, diamond or mixtures of these types of crystals.

Die Schleifkörner (12) sind so im Einbettmedium (11) angeordnet, daß stets spitze und/oder scharfe Kanten der eingebetteten Kristalle aus dem Einbettmedium herausragen und somit ein insgesamt zackiges Schleifprofil bilden.The abrasive grains (12) are arranged in the embedding medium (11) in such a way that pointed and / or sharp edges of the embedded crystals always protrude from the embedding medium and thus form an overall jagged grinding profile.

Das Einbettmedium (11) ist bei der dargestellten Ausführungsform Nickel und wurde galvanisch auf die Scheide (3) aufgetragen, so daß an den Rändern der Schleifmittelschicht (10) keine scharfen Absätze oder Kanten vorhanden sind. Vielmehr geht die Schleifmittelschicht allmählich in die Oberfläche der Scheide (3) über, wie Figur 2 zeigt.The embedding medium (11) is nickel in the embodiment shown and was applied galvanically to the sheath (3), so that there are no sharp shoulders or edges at the edges of the abrasive layer (10). Rather, the abrasive layer gradually merges into the surface of the sheath (3), as shown in Figure 2.
