Description

Die Erfindung betrifft ein Messer mit Tülle, in die wenigstens die Klinge des Messers versenkbar ist, wobei auf einem an der Tülle vorgesehenen Sockelkörper mit einer seitlichen Ausneh­mung eine Scherplatte angebracht ist, welche an einer Seite eine über der Ausnehmung des Sockelkörpers liegende nasenarti­ge Ausnehmung aufweist und auf welcher ein T-förmig ausgebil­deter Bolzen angeordnet ist, wobei die Klinge wenigstens eine Scherschneide aufweist und wobei in der Klinge weiterhin eine Öffnung vorgesehen ist, durch welche der Bolzen durchführbar ist.The invention relates to a knife with a grommet into which at least the blade of the knife can be countersunk, a shear plate having a side recess on a base body provided on the grommet, which has on one side a nose-like recess lying above the recess of the base body and on which a T-shaped bolt is arranged, wherein the blade has at least one cutting edge and wherein an opening is also provided in the blade through which the bolt can be passed.

Mit solchen bekannten Messern können Drähte oder ähnliches stangenartiges Material abgeschnitten werden. Dazu wird das Messer mit der Öffnung in der Klinge so über den Bolzen auf der Schneidplatte der Tülle gelegt, daß das Messer um die Bolzenachse schwenkbar ist, wobei die Bolzenachse gleichzei­tig dazu dient, die Klinge des Messers abzustützen. Die Scher­schneide bildet dann zusammen mit der nasenartigen Ausnehmung der Scherplatte das eigentliche Schneidwerkzeug. Ein Draht wird zum Abschneiden in die nasenartige Ausnehmung eingelegt, worauf dann die Messerklinge mit der Scherschneide auf das ab­zuschneidende Stück zubewegt wird und dieses zunächst klemmt und dann schneidet. Die unter der Schneidplatte liegende Aus­nehmung des Sockelskörpers ist bei den bekannten Messern nahe­zu kongruent mit der nasenförmigen Ausnehmung der Schneidplat­te ausgebildet. Dieses ermöglicht einen gewissen Greifeffekt des zu schneidenden Materials. Ein straff gespannter Draht wird so von dem Vorsprung an der Schneidplatte als auch von dem entsprechend ausgebildeten Vorsprung des Sockelkörpers auf einer gewissen Breite übergriffen, so daß der Abschneidevor­gang unter Druckbelastung des straff gespannten Materials und der Schneidbewegung der Klinge erfolgt. Dabei kann es nun pas­sieren, daß sich das abzuschneidende Material zwischen der Klinge und der Schneidplatte verklemmt, da diese ein gewisses Spiel zueinander aufweisen. Das angeschnittene Material setzt sich somit klemmend in der Schere fest und beeinträchtigt das Durchtrennen oder macht es gar völlig unmöglich. Der verklemm­te Draht kann auch nicht durch Bewegen der aus Messer und Tül­le gebildeten Schere bewegt werden, da durch das Aufsetzen auf den straff gespannten Draht und der Greifwirkung von Sockel­körper und Scherplatte kein Spielraum für den Draht bleibt, in der zum Lösen des Verklemmens erforderlichen Richtung auszu­weichen.Such known knives can be used to cut wires or similar rod-like material. For this purpose, the knife with the opening in the blade is placed over the bolt on the cutting plate of the spout so that the knife around the The pin axis is pivotable, the pin axis also serving to support the blade of the knife. The shear blade then forms the actual cutting tool together with the nose-like recess of the shear plate. A wire is inserted into the nose-like recess for cutting, whereupon the knife blade with the cutting edge is moved towards the piece to be cut and this is first clamped and then cut. In the known knives, the recess of the base body lying under the insert is almost congruent with the nose-shaped recess of the insert. This enables a certain gripping effect of the material to be cut. A taut wire is overlapped by the projection on the cutting plate as well as by the appropriately designed projection of the base body over a certain width, so that the cutting process takes place under pressure loading of the taut material and the cutting movement of the blade. It can now happen that the material to be cut gets stuck between the blade and the cutting plate, since they have a certain amount of play with one another. The cut material is jammed in the scissors and impairs cutting or makes it completely impossible. The jammed wire can also not be moved by moving the scissors made of knife and grommet, because by placing it on the tightly tensioned wire and the gripping action of the base body and the shear plate, there is no scope for the wire to evade in the direction required to loosen the jam .

Es ist daher die Aufgabe der Erfindung, das bekannte Messer mit Tülle so zu verbessern, daß mit dem aus Messer und Tülle gebildeten Schneidwerkzeug auch solches Material sauber ge­schnitten werden kann, das dazu neigt, sich in dem Schneid­werkzeug klemmend festzusetzen.It is therefore the object of the invention to improve the known knife with grommet so that with the cutting tool formed from the knife and grommet it is also possible to cleanly cut material which tends to become jammed in the cutting tool.

Diese Aufgabe wird von einem Messer mit Tülle der eingangs genannten Gattung mit den Merkmalen des Kennzeichens von An­spruch 1 gelöst. Eine vorteilhafte Ausgestaltung ist Gegen­stand des Unteranspruchs.This object is achieved by a knife with a grommet of the type mentioned at the outset with the features of the characterizing part of claim 1. An advantageous embodiment is the subject of the dependent claim.

Beim Messer mit Tülle gemäß der vorliegenden Erfindung ist die Ausnehmung des Sockelkörpers U-förmig ausgebildet und in ihrem tiefsten Bereich dem tiefsten Bereich der nasenartigen Ausneh­mung im wesentlichen kongruent, während sie im Bereich eines unterhalb der nasenartigen Ausnehmung gebildeten Vorsprungs hinter diesen zurücktritt.In the case of a knife with a spout according to the present invention, the recess of the base body is U-shaped and in its deepest region it is essentially congruent with the deepest region of the nose-like recess, while in the region of a projection formed below the nose-like recess it recedes behind it.

Wenn nun das Schneid- oder Scherwerkzeug auf die oben be­schriebene Weise gebildet und zum Schneiden beispielsweise straff gespannten Drahtmaterials verwendet wird, kann das Werkzeug auch dann noch bewegt werden, wenn sich der abzu­schneidende Teil des Materials zwischen Klinge und Scherplat­te verklemmt hat, denn beim Bewegen des Scherwerkzeuges be­sitzt das Material auch noch eine gewisse Bewegungsfreiheit der Schneidrichtung entgegen, was notwendig ist, damit das Klemmen des Materials beseitigt wird, da das Material nicht mehr unmittelbar am Sockelkörper anliegt. Die Greifwirkung bleibt jedoch wegen der nach wie vor nasenartig gestalteten Ausnehmung der Schneidplatte erhalten.If the cutting or shearing tool is now formed in the manner described above and is used for cutting, for example, tightly tensioned wire material, the tool can still be moved even if the part of the material to be cut has become jammed between the blade and the shaving plate, because when moving the The material of the shaving tool also has a certain freedom of movement in the direction of the cutting, which is necessary so that the clamping of the material is eliminated since the material no longer lies directly against the base body. However, the gripping effect is retained due to the recess of the cutting plate which is still nose-shaped.

Wenn die Ausnehmung des Sockelkörpers mit diesem eine Ecke bildet, die über die nasenartige Ausnehmung und über die Schneidplatte hinausragt, kann sich das zu schneidende Mate­rial an dieser Ecke abstützen, wodurch vermieden wird, daß es der Schneidbewegung ausweicht.If the recess of the base body forms a corner with the latter, which protrudes beyond the nose-like recess and beyond the cutting plate, the material to be cut can be supported at this corner, thereby avoiding that it avoids the cutting movement.

Das Heft 10 besteht beispielsweise aus Kunststoff und ist durch darauf ausgeform­te Rippen griffsicher gestaltet. Am oberen Ende des Heftes 10 ist eine Klemmeinrichtung 9 angebracht, die zum Aufpflanzen das Messers auf ein Gewehr dient. Die Klinge 11 weist eine Messerschneide 12 auf, die zur Spitze 15 des Messers 1 hin leicht konvex gekrümmt ist. Am Messerrücken ist im Bereich nahe des Heftes 10 eine Säge 16 vorgesehen, an die sich in Richtung auf die Spitze 15 des Messers 1 eine Scherschneide 13 anschließt. Zwischen Scherschneide 13 und Spitze 15 ist eine weitere leicht konkav ausgebildete Schneide 14 vorge­sehen, die in der Spitze 15 des Messers 1 mit der Messer­schneide 12 zusammentrifft. In Höhe der Scherschneide 13 ist auf der Klinge 11 eine Öffnung 17 vorgesehen, die im wesent­lichen rechteckförmig ist. An der Unterseite des Heftes 10 befindet sich ein fest mit diesem verbundener Hebel 19 sowie gegenüberliegend ein Ring 18, wobei diese Einrichtungen als Werkzeuge Verwendung finden.The knife 1 shown in FIG. 1 has a blade 11 which is firmly connected to a booklet 10. The booklet 10 is made of plastic, for example, and is designed so that it can be gripped by ribs formed thereon. At the top of the booklet 10, a clamping device 9 is attached, which is used to plant the knife on a rifle. The blade 11 has a knife edge 12 which is slightly convex towards the tip 15 of the knife 1. A saw 16 is provided on the back of the knife in the area near the handle 10, which is followed by a shear blade 13 in the direction of the tip 15 of the knife 1. A further, slightly concave cutting edge 14 is provided between the cutting edge 13 and the tip 15, which meets the cutting edge 12 in the tip 15 of the knife 1. At the level of the shear blade 13, an opening 17 is provided on the blade 11, which is essentially rectangular. On the underside of the booklet 10 there is a lever 19 which is fixedly connected to this and a ring 18 opposite, these devices being used as tools.

Fig. 2 zeigt eine Tülle 2, in die die Klinge 11 des Messers 1 versenkbar ist. Die Tülle weist in ihrem oberen Bereich einen Anschlag 26 für das Heft 10 bzw. die an dem Heft angebrachten Werkzeuge auf. Am Anschlag 26 ist weiterhin ein Befestigungs­stück 27 vorgesehen, in das ein Gurt 29 oder dergleichen mit­tels einer Schnappfeder 28 eingreifen kann. Die Tülle 2 be­steht weiterhin aus einem Gehäuse 20 aus starrem, unnachgie­bigem Material, dessen unterer Bereich als Sockelkörper 22 ausgebildet ist. Auf dem Sockelkörper 22 ist eine Schneidplat­te 3 mit Hilfe von drei Schrauben 35, 36, 37 befestigt. Die Schrauben 35, 36 sind versenkt, die Schraube 37 ist erhöht und dient gleichzeitig als Anschlag für die Scherschneide 13, wenn aus Messer 1 und Tülle 2 das Schneid- oder Scherwerkzeug ge­bildet wird. Auf der Scherplatte 3 ist ein Bolzen vorgesehen, dessen Bolzenplatte 31 in ihren äußeren Abmessungen so gestal­tet ist, daß sie genau in die Öffnung 17 des Messers 1 geführt werden kann. Der Sockelkörper 22 schließt mit einer Erhöhung 21 ab, die als Anschlag für die Scherplatte 3 dient. Die Scherplatte 3 ist in ihrem oberen Bereich winklig ausgebildet und liegt an einer ebensolchen winkligen Ausnehmung der Erhöhung 21 an, so daß die Scherplatte 3 gegen ein Verschwenken weit­gehend gesichert ist. Am unteren Bereich der Scherplatte 3 ist eine Schraubklinge 32 als zusätzliches Werkzeug vorge­sehen. Die Scherplatte 3 weist weiterhin eine seitlich ange­ordnete nasenartige Ausnehmung 33 auf, die zusammen mit einem Vorsprung 34 der Scherplatte 3 gewährleistet, daß ein in die nasenartige Ausnehmung 33 geführtes Materialstück greifend ge­halten wird. Der Sockelkörper 22 ist im Bereich der nasenarti­gen Ausnehmung 33 ebenfalls mit einer Ausnehmung 23 versehen.Fig. 2 shows a spout 2, in which the blade 11 of the knife 1 can be lowered. The spout has one in its upper area Stop 26 for the booklet 10 or the tools attached to the booklet. At the stop 26, a fastening piece 27 is also provided, in which a belt 29 or the like can engage by means of a snap spring 28. The grommet 2 also consists of a housing 20 made of rigid, unyielding material, the lower region of which is designed as a base body 22. A cutting plate 3 is fastened on the base body 22 with the aid of three screws 35, 36, 37. The screws 35, 36 are countersunk, the screw 37 is raised and at the same time serves as a stop for the cutting edge 13 when the cutting or shearing tool is formed from the knife 1 and the spout 2. A bolt is provided on the shear plate 3, the outer dimensions of the bolt plate 31 being designed such that it can be guided precisely into the opening 17 of the knife 1. The base body 22 ends with an elevation 21, which serves as a stop for the shear plate 3. The shear plate 3 is angled in its upper region and lies against such an angled recess of the elevation 21, so that the shear plate 3 is largely secured against pivoting. At the lower area of the shear plate 3, a screw blade 32 is provided as an additional tool. The shear plate 3 also has a laterally arranged nose-like recess 33 which, together with a projection 34 of the shear plate 3, ensures that a piece of material guided into the nose-like recess 33 is held in a gripping manner. The base body 22 is also provided with a recess 23 in the region of the nose-like recess 33.

Fig. 3 zeigt die Anordnung der Scherplatte 3 und des Sockel­körpers 22 mit ihren Ausnehmungen 23, 33 im Detail. Die Aus­nehmung 23 der Sockelplatte 22 ist im wesentlichen U-förmig und verläuft in ihrem tiefsten Bereich 41 in etwa kongruent mit der nasenartigen Ausnehmung 33, wenn auch der tiefste Bereich 38 der nasenartigen Ausnehmung 33 etwas über dem tief­sten Bereich 41 hervorsteht. Der Sockelkörper 22 bildet mit der Ausnehmung 23 eine Ecke 40, die über die Scherplatte 3 und deren nasenartige Ausnehmung 33 hinausragt. Die Ausneh­mung 23 tritt im unteren Bereich des Sockelkörpers 22 hinter einem Vorsprung 34 der Scherplatte 3 zurück. Der Bolzen ist auf der Zentralachse der Scherplatte 3 angeordnet, wobei die Bolzenplatte 31 mit ihrer Längsachse etwa um 40° gegen die Zentralachse der Scherplatte 3 geschwenkt ist. Die versenk­ten Schrauben 35 und 36 sind beidseitig des Bolzens angeord­net. Die als Anschlag dienende Schraube 37 ist im unteren Bereich der Scherplatte ebenfalls auf der Zentralachse ange­bracht. Die als Anschlag für die Scherplatte 3 dienende Er­höhung 21 ist sowohl mit dem Sockelkörper 22 als auch mit dem Gehäuse 20 einstückig ausgeformt.Fig. 3 shows the arrangement of the shear plate 3 and the base body 22 with their recesses 23, 33 in detail. The recess 23 of the base plate 22 is essentially U-shaped and extends in its deepest region 41 approximately congruently with the nose-like recess 33, even if the deepest region 38 of the nose-like recess 33 protrudes somewhat above the deepest region 41. The base body 22 also forms the recess 23 has a corner 40 which projects beyond the shear plate 3 and its nose-like recess 33. The recess 23 is in the lower region of the base body 22 behind a projection 34 of the shear plate 3. The pin is arranged on the central axis of the shear plate 3, the pin plate 31 having its longitudinal axis being pivoted about 40 ° against the central axis of the shear plate 3. The countersunk screws 35 and 36 are arranged on both sides of the bolt. The screw 37 serving as a stop is also attached to the central axis in the lower area of the shear plate. The elevation 21 serving as a stop for the shear plate 3 is formed in one piece with both the base body 22 and the housing 20.

Fig. 4 zeigt den unteren Bereich der Tülle 2 mit dem Sockel­körper 22. Eine als Zentrierhilfe dienende Bohrung 24 ist im unteren Bereich des Sockelkörpers vorgesehen, in diese Boh­rung greift ein entsprechender Nocken der Scherplatte 3 ein. In der Nähe der Schraubklinge 32 ist am Sockelkörper 22 eine Durchführung 25 angebracht, durch die eine Schnur oder der­gleichen gezogen werden kann. Die Ausnehmung 23 des Sockel­körpers 22 tritt in ihrem unteren Bereich hinter die nasen­artige Ausnehmung 33 und den Vorsprung 34 zurück, während sie im oberen Bereich mit der Ecke 40 über die Scherplatte 3 hin­ausragt.4 shows the lower area of the grommet 2 with the base body 22. A bore 24 serving as a centering aid is provided in the lower area of the base body, a corresponding cam of the shear plate 3 engages in this bore. In the vicinity of the screw blade 32, a bushing 25 is attached to the base body 22, through which a cord or the like can be pulled. The recess 23 of the base body 22 is in its lower region behind the nose-like recess 33 and the projection 34, while in the upper region it projects with the corner 40 over the shear plate 3.

Fig. 5 zeigt eine Seitenansicht der im Zusammenhang mit Fig. 3 und Fig. 4 beschriebenen Anordnung. Der auf der Scherplatte 3 angeordnete Bolzen besteht aus Bolzenschaft 30 und Bolzenplat­te 31. Die Höhe des Bolzenschaftes 30 ist dabei so gewählt, daß die Klinge 11 mit Spiel zwischen der Scherplatte 3 und der Bolzenplatte 31 schwenkbar ist, d. h., sie ist um kleine Win­kel kippbar. Die Scherplatte 3 ragt wenig über die Erhöhung 21 hervor. Der Abstand zwischen Schraube 37 und Bolzenschaft 30 ist so gewählt, daß der Rückenbereich der Klinge 11 sich zwischen diesen beiden Teilen bewegen kann und daß die Scher­schneide 13 nach Beenden der Scherbewegung gegen die Schraube 37 anschlägt. Die Schraubklinge 32 ragt über den Sockelkörper 22 hinaus. Die Ausnehmung 23 ist in ihren Gesamtabmessungen größer als die nasenartige Ausnehmung 33, wodurch dem Teil des zu schneidenden Materials, der nicht abgeschert wird, ein ge­wisses Spiel gegeben wird.FIG. 5 shows a side view of the arrangement described in connection with FIGS. 3 and 4. The bolt arranged on the shear plate 3 consists of bolt shank 30 and bolt plate 31. The height of the bolt shank 30 is chosen so that the blade 11 can be pivoted with play between the shear plate 3 and the bolt plate 31, ie it can be tilted by small angles . The shear plate 3 protrudes little above the elevation 21. The distance between screw 37 and bolt shaft 30 is chosen so that the back area of the blade 11 is can move between these two parts and that the cutting edge 13 strikes against the screw 37 after completion of the shearing movement. The screw blade 32 projects beyond the base body 22. The overall dimensions of the recess 23 are larger than the nose-like recess 33, as a result of which a certain play is given to the part of the material to be cut which is not sheared off.

Fig. 6 zeigt die Anordnung von Messer 1 und Tülle 2 als Schneidwerkzeug im Detail. Die Klinge 11 ist mit der Öffnung 17 über die Bolzenplatte 31 geführt und kann sich um den Bol­zenschaft 30 als Achse bewegen. Das abzuschneidende Material­stück wird in die tiefste Stelle der nasenartigen Ausnehmung 33 gelegt. Sodann wird die Klinge 11 in Pfeilrichtung in den Bolzenschaft 30 bewegt, bis das Material abgeschnitten ist. Nach Beendigung der Schneidbewegung schlägt die Scherschneide 13 an die Schraube 37 an.Fig. 6 shows the arrangement of knife 1 and spout 2 as a cutting tool in detail. The blade 11 is guided with the opening 17 over the bolt plate 31 and can move about the bolt shaft 30 as an axis. The piece of material to be cut is placed in the deepest point of the nose-like recess 33. The blade 11 is then moved in the direction of the arrow into the bolt shaft 30 until the material is cut off. After the cutting movement has ended, the cutting edge 13 strikes the screw 37.

Durch die Erfindung soll also vermieden werden, daß das Schneidgut beim Schneidvorgang kippt, denn durch Kippen kann das Schneidgut die Klinge von der Scherplatte wegdrücken. Dadurch würde der Schnitt ungenau und u.U. sogar das Schneidgut überhaupt nicht durchgetrennt bzw. geschnitten, sondern nur verbogen.The aim of the invention is to avoid that the material to be cut tilts during the cutting process, because by tilting the material to be cut can push the blade away from the shear plate. This would make the cut imprecise and possibly even the material to be cut is not cut or cut at all, but only bent.

Ein Kippen des Schneidgutes kann insbesondere erfolgen, wenn das Schneidgut besonders hart ist und/oder wenn die Schneidkanten von Klinge und Scherplatte nicht mehr ganz scharf sind und/oder wenn das Spiel zwischen Klinge und Scherplatte zu groß ist.The material to be cut can tip over in particular if the material to be cut is particularly hard and / or if the cutting edges of the blade and the shear plate are no longer very sharp and / or if the play between the blade and the shear plate is too great.

Um zu verhindern, daß das Schneidgut kippen und damit Klinge und Scherplatte in unerwünschtem Ausmaß auseinanderdrücken kann, ist erfindungsgemäß ein Gegenhalt für das Schneidgut vorgeschlagen worden. Die V- oder U-förmige Nasenausnehmung ist zu diesem Zweck wie beschrieben ausgebildet.In order to prevent the material to be tipped from tilting and thus the blade and shaving plate being able to be pushed apart to an undesirable extent, a counterhold for the material to be cut has been proposed according to the invention. For this purpose, the V- or U-shaped nose recess is designed as described.
