Description

Die Erfindung betrifft ein Klappmesser nach dem Oberbegriff des Anspruchs 1.The invention relates to a folding knife according to the preamble of claim 1.

Bei derartigen Klappmessern ist der Anschlag am Federbalken im allgemeinen an einem sich zum Klingenteil hin erstreckenden Hakenteil ausgebildet, welches sich unter einer Federkraft im Bereich der Querachse in eine dazu komplementäre Nut des Klingenteils erstreckt, so daß das Klingenteil in der ausgestellten Lage, wo es axial im wesentlichen mit dem Griffteil ausgerichtet ist, in beiden Schwenkrichtungen fixiert ist. Durch Verschwenken des Federbalkens von Hand gegen die Federkraft wird dann das Hakenteil aus der Nut herausgehoben, worauf sich das Klingenteil dann auf das Griffteil zurückschwenken läßt, wo insbesondere die Schneide in einem schlitzartigen Unterbringungsraum versenkt angeordnet ist.In such folding knives, the stop on the cantilever is generally formed on a hook part extending towards the blade part, which extends under spring force in the region of the transverse axis into a complementary groove of the blade part, so that the blade part in the position shown, where it is axial is essentially aligned with the handle part, is fixed in both pivot directions. By swiveling the cantilever by hand against the spring force, the hook part is then lifted out of the groove, whereupon the blade part can then be pivoted back onto the grip part, where in particular the cutting edge is sunk in a slot-like accommodation space.

Bei bekannten Klappmessern dieser Art ist entweder der Federbalken um eine Querachse verschwenkbar am Griffteil angeordnet und wird durch eine besondere Feder in die Eingriffslage vorgespannt. Der Federbalken kann aber auch an dem vom Anschlagende abgewandten Endbereich formschlüssig mit dem Griffteil verbunden sein und durch einen besonderen Hebel unter federnder Verbiegung so verschwenkt werden, daß der Hakenteil aus der Nut des Klingenteils herausgehoben wird. In letzterem Teil muß der Federbalken selbst entsprechende elastische Eigenschaften aufweisen.In known folding knives of this type, either the cantilever is arranged on the handle part so as to be pivotable about a transverse axis and is biased into the engagement position by a special spring. The cantilever can also be positively connected to the handle part at the end area facing away from the stop end and by a special lever with resilient bending be pivoted so that the hook part is lifted out of the groove of the blade part. In the latter part, the cantilever itself must have appropriate elastic properties.

In jedem Fall ist der Federbalken in einer längsschlitzartigen Ausnehmung des Griffteils versenkt untergebracht, welche unmittelbar über dem schlitzartigen Unterbringungsraum für das Klingenteil liegt. Die Unterbringung des Federbalkens in der längsschlitzartigen Ausnehmung ist auf jeden Fall derart, daß der Federbalken bei Beaufschlagung von Hand die erforderlichen Schwenkbewegungen ausführen kann, also entsprechend beweglich gelagert ist.In any case, the cantilever is sunk in a longitudinal slot-like recess of the handle part, which lies directly above the slot-like accommodation space for the blade part. The accommodation of the cantilever in the longitudinal slot-like recess is in any case such that the cantilever can carry out the required pivoting movements when it is acted upon by hand, that is to say is mounted in a correspondingly movable manner.

Während das Vorsehen einer besonderen Rückstellfeder aufwendig ist und die Bereitstellung eines weiteren störanfälligen Bauteils in Form der Feder erfordert, muß bei Verwendung des Federbalkens selbst als rückfederndes Element ein besonderer Hebel zum Herausheben des Hakenteils aus der Nut vorgesehen sein.While the provision of a special return spring is complex and requires the provision of a further fault-prone component in the form of the spring, a special lever for lifting the hook part out of the groove must be provided when the spring beam itself is used as a spring-back element.

Aus der US-A 2 263 415 ist bereits ein Klappmesser bekannt, bei welchem ein Gabelglied am Griffteil axial verschiebbar angeordnet ist, um das schwenkbar am Griffteil befestigte Klingenteil wahlweise für ein Verschwenken relativ zum Griffteil freizugeben oder in der ausgeschwenkten Lage zu fixieren. Bei einer anderen Ausführungsform sind am Griffteil miteinander zusammenwirkende, um jeweils eine eigene Achse verschwenkbare Hebel vorgesehen, um das Klingenteil wahlweise in der ausgeklappten Stellung zu fixieren oder in das Griffteil zurückklappen zu können. Sowohl das Erfordernis eines axial verschiebbaren Gabelgliedes als auch von drei verschiedenen, um jeweils eine Querachse verschwenkbaren Hebeln führen zu einem erhöhten Herstellungsaufwand, erschweren die Bedienbarkeit und beeinträchtigen die Funktionssicherheit.From US-A 2 263 415 a folding knife is already known, in which a fork member is axially displaceably arranged on the handle part in order to either release the blade part pivotally attached to the handle part for pivoting relative to the handle part or to fix it in the pivoted-out position. In another embodiment, mutually cooperating levers are provided on the handle part, each pivotable about its own axis, in order to be able to fix the blade part either in the unfolded position or to fold it back into the handle part. Both the requirement of an axially displaceable fork member and of three different levers, each pivotable about a transverse axis, lead to increased production costs, make operation more difficult and impair functional reliability.

Das Ziel der Erfindung besteht darin, ein weiteres Klappmesser der eingangs genannten Gattung bereitzustellen. Insbesondere soll durch das erfindungsgemäße Klappmesser das Erfordernis besonderer Federelemente oder besonderer und extra angelenkter Betätigungshebel vermieden werden.The aim of the invention is to provide a further folding knife of the type mentioned at the beginning. In particular, the need for special spring elements or special and articulated actuating levers is to be avoided by the folding knife according to the invention.

Zur Lösung dieser Aufgabe sind die Merkmale des kennzeichnenden Teils des Anspruchs 1 vorgesehen.To achieve this object, the features of the characterizing part of claim 1 are provided.

Auf diese Weise werden nicht nur die federnden Eigenschaften des Federbalkens selbst zur Bereitstellung der erforderlichen federnden Eingriffskraft ausgenutzt, sondern es wird insbesondere gewährleistet, daß die Schwenkachse sowie die Anschlagflächen sich vergleichsweise nahe der Querachse des Klingenteils befinden können, so daß nach hinten noch ein relativ langer Hebelarm zur Verfügung steht, der von der Bedienungsperson auch bequem unmittelbar beaufschlagt werden kann, so daß Zwischen-Übertragungshebel vermieden werden.In this way, not only are the resilient properties of the spring bar itself used to provide the required resilient engagement force, Rather, it is ensured in particular that the pivot axis and the stop surfaces can be located comparatively close to the transverse axis of the blade part, so that a relatively long lever arm is still available to the rear, which can also be conveniently acted upon directly by the operator, so that intermediate Transmission levers are avoided.

Durch eine entsprechende Wahl des axialen Abstandes der Anschlagflächen sowie die Länge des Hebelarms kann praktisch jede gewünschte Kraftübersetzung verwirklicht werden, so daß trotz der für die Aufspreizung des Längsschlitzes erforderlichen, vergleichsweise großen Kräfte die von Hand am Ende des Hebels aufzubringende Betätigungskraft in den Grenzen liegt, wie sie für die Betätigung derartiger Klappmesser üblich ist.Through a suitable choice of the axial distance between the stop surfaces and the length of the lever arm, practically any desired power transmission can be realized, so that despite the comparatively large forces required for the expansion of the longitudinal slot, the actuating force to be applied by hand at the end of the lever is within the limits. as is usual for the operation of such folding knives.

Besonders vorteilhaft ist der Federbalken gemäß Anspruch 2 auch axial, d.h. in seiner Längsrichtung festgelegt.The spring beam according to claim 2 is also particularly advantageous axially, i.e. set in its longitudinal direction.

Zwei vorteilhafte Ausführungsformen sind durch die Ansprüche 3 und 4 gekennzeichnet.Two advantageous embodiments are characterized by claims 3 and 4.

Die gemäß Anspruch 5 vorgesehene Drehführung für den Federbalken am Griffteil dient einer einfachen Herstellung, denn nach der Montage des Drehführungsstiftes am Griffteil bei ausgestelltem Klingenteil und in die Nut eingreifenden Hakenteil des Federbalkens, welcher nicht vorgespannt ist, kann die Klinge abgenommen und vor Montage der Anschlagstifte der Federbalken um einen geringen Winkelbetrag so verschwenkt werden, daß bei anschließendem Einsetzen des Klingenteils die erforderliche federnde Vorspannung vorliegt.The provided according to claim 5 rotary guide for the cantilever on the handle part serves a simple manufacture, because after installing the rotary guide pin on the handle part with the blade part exposed and engaging in the groove hook part of the cantilever, which is not preloaded, the blade can be removed and before mounting the stop pins the cantilever is pivoted by a small amount of angle so that the required resilient bias is present when the blade part is subsequently inserted.

Es ist wichtig, daß die erfindungsgemäßen Anschlagflächen an Anschlagelementen ausgebildet sind, die auch eine axiale Fixierung des Federbalkens in sämtlichen Schwenklagen gewährleisten.It is important that the stop surfaces according to the invention are formed on stop elements which also ensure an axial fixation of the cantilever in all pivot positions.

Dies kann bevorzugt durch die Maßnahme des Anspruchs 6 geschehen.This can preferably be done by the measure of claim 6.

Nach den Fig. 1 bis 3 weist das erfindungsgemäße Klappmesser einen Griffteil 11 und einen um eine Querachse 13 daran schwenkbar angeordneten Klingenteil 12 auf. Am Klingenteil ist die Schneide 37 vorgesehen. In der von der Schneide 37 abgewandten Seite des Griffteils 11 ist eine längsschlitzartige Ausnehmung 34 vorgesehen, in der ein länglicher Federbalken 14 mit rechteckförmigem Querschnitt seitlich geführt, jedoch in Richtung der Schwenkbewegung des Klingenteils 12 verschieblich untergebracht ist.According to FIGS. 1 to 3, the folding knife according to the invention has a handle part 11 and a blade part 12 arranged thereon about a transverse axis 13. The cutting edge 37 is provided on the blade part. In the side of the handle part 11 facing away from the cutting edge 37, a longitudinal slot-like recess 34 is provided, in which an elongated spring bar 14 with a rectangular cross section is guided laterally, but is displaceably accommodated in the direction of the pivoting movement of the blade part 12.

Nach den Fig. 1, 4 und 4a weist der Federbalken einen in Richtung der Querachse 13 vollständig durch ihn hindurchgehenden Längsschlitz 18 auf. Der Längsschlitz 18 muß sich nur im wesentlichen in Längsrichtung des Griffteils 11 bzw. des Federbalkens 14 erstrecken und kann auch insgesamt oder teilweise etwas von dieser Längsrichtung abweichen, wie das aus den Fig. 1, 4 und 5 hervorgeht.1, 4 and 4a, the cantilever has a longitudinal slot 18 which passes completely through it in the direction of the transverse axis 13. The longitudinal slot 18 only has to extend essentially in the longitudinal direction of the handle part 11 or the spring bar 14 and can also deviate somewhat or in whole or in part from this longitudinal direction, as can be seen from FIGS. 1, 4 and 5.

Nach den Fig. 4 und 4a befindet sich der Längsschlitz 18 bevorzugt in der dem vorderen Hakenteil 31 zugewandten Hälfte des Federbalkens 14. Das Hakenteil 31 greift nach Fig. 1 in eine Nut 32 des Klingenteils ein, und zwar im wesentlichen über der Querachse 13, so daß das Hakenteil 31 beim Außer-Eingriff-Bringen mit der Nut 32 eine Bewegung im wesentlichen von der Querachse 13 weg ausführt.4 and 4a, the longitudinal slot 18 is preferably located in the half of the spring bar 14 facing the front hook part 31. The hook part 31 engages in a groove 32 of the blade part according to FIG. 1, essentially over the transverse axis 13, so that the hook member 31 performs a movement substantially away from the transverse axis 13 when disengaged from the groove 32.

Das Hakenteil 31 weist einen vorderen Anschlag 16 und einen rückwärtigen Anschlag 38 auf, die mit durch die Flanken der Nut 32 gebildeten Gegenanschlägen 17 bzw. 39 des Klingenteils 12 zusammenwirken. Durch den Eingriff des Hakenteils 31 in die Nut 32 wird das Klingenteil 12 in der in den Fig. 1 bis 3 dargestellten ausgestellten Lage relativ zum Griffteil 11 drehfixiert. Hierzu muß der Federbalken 14 in der im folgenden im einzelnen beschriebenen Weise innerhalb des Griffteils 11 axial ausreichend festgelegt sein.The hook part 31 has a front stop 16 and a rear stop 38 which cooperate with counter stops 17 and 39 of the blade part 12 formed by the flanks of the groove 32. The blade part becomes by the engagement of the hook part 31 in the groove 32 12 in the shown position shown in FIGS. 1 to 3 rotatably fixed to the handle part 11. For this purpose, the spring bar 14 must be sufficiently axially fixed within the handle part 11 in the manner described in detail below.

Nach den Fig. 4 und 4a weist der Längsschlitz 18 im axialen Abstand drei im wesentlichen kreisförmige Erweiterungen 27, 28, 30 auf, die sich parallel zur Querachse 13 erstrecken und von komplementären Anschlagstiften 25, 26 bzw. einem Drehführungsstift 29 durchsetzt werden, die mit beiden Enden am Griffteil 11 festgelegt sind.4 and 4a, the longitudinal slot 18 has three substantially circular extensions 27, 28, 30 at axial distance, which extend parallel to the transverse axis 13 and are penetrated by complementary stop pins 25, 26 and a rotary guide pin 29, respectively Both ends are fixed on the handle part 11.

Auf diese Weise wird der Längsschlitz 18 in vier Abschnitte 18a, 18b, 18c, 18d unterteilt, die in der aus den Fig. 4 und 4a ersichtlichen Weise zumindest im wesentlichen tangential in den Erweiterungen 27, 28, 30 münden, derart, daß der Federbalken 14 in den beiden Axialrichtungen 40 durch die so gebildeten Axialanschlagflächen 47, 48 am Federbalken 14 und die Gegen-Anschlagflächen 49, 50 an den Stiften 25, 26, 29 auch im gespreizten Zustand des Längsschlitzes 18 so sicher festgelegt ist, daß eine einwandfreie und sichere Fixierung des Klingenteils 12 in der ausgestellten Lage nach Fig. 1 gewährleistet ist.In this way, the longitudinal slot 18 is divided into four sections 18a, 18b, 18c, 18d, which in the manner shown in FIGS. 4 and 4a open at least substantially tangentially in the extensions 27, 28, 30, such that the cantilever 14 in the two axial directions 40 by the axial stop surfaces 47, 48 thus formed on the spring beam 14 and the counter-stop surfaces 49, 50 on the pins 25, 26, 29, even in the spread state of the longitudinal slot 18, is so securely fixed that a perfect and safe Fixation of the blade part 12 in the position shown in FIG. 1 is guaranteed.

Aufgrund der beschriebenen Anordnung steht auf der vom Hakenteil 31 abgewandten Seite des Federbalkens 14 ein vergleichsweise langer Betätigungs-Hebelarm 35 zur Verfügung, an den sich noch ein beispielsweise an die Fingerform angepaßtes Betätigungsteil 36 anschließen kann, das aus dem Griffteil 11 nach außen vorsteht.Due to the arrangement described, a comparatively long actuating lever arm 35 is available on the side of the spring bar 14 facing away from the hook part 31, to which an actuating part 36 adapted for example to the finger shape can also be connected, which protrudes outward from the grip part 11.

Die Montage des erfindungsgemäßen Klappmessers geht wie folgt vor sich:The folding knife according to the invention is assembled as follows:

Zunächst wird das Klingenteil 12 mit dem Federbalken 14 durch Anbringen eines Zapfens 41 im Bereich der Drehachse 13 und nur des Drehführungsstiftes 29 in der Erweiterung 30 am Griffteil 11 angebracht, und zwar in der in den Fig. 1 bis 3 dargestellten Eingriffsposition des Hakenteils 31 und der Nut 32. Der Federbalken 14 ist hierbei noch nicht federnd verspannt.First, the blade part 12 with the spring bar 14 is attached by attaching a pin 41 in the region of the axis of rotation 13 and only the rotary guide pin 29 in the extension 30 on the handle part 11, specifically in the engagement position of the hook part 31 and the groove 32. The spring bar 14 is not yet resiliently clamped.

Anschließend wird dann das Klingenteil 12 durch Herausnehmen des Zapfens 41 demontiert und der Federbalken 14 anschließend in den Ansichten der Fig. 1 und 4 etwas entgegen dem Uhrzeigersinn um die Schwenkachse 15, die mit der Achse des Drehführungsstiftes 29 zusammenfällt geschwenkt. Anschließend werden dann die Löcher für die Anschlagstifte 25, 26 gebohrt und die Anschlagstifte 25, 26 in die Erweiterungen 27, 28 eingesteckt und am Griffteil 11 festgelegt.Then the blade part 12 is then dismantled by removing the pin 41 and the spring bar 14 is then pivoted somewhat counterclockwise in the views of FIGS. 1 and 4 about the pivot axis 15, which coincides with the axis of the rotary guide pin 29. Then the holes for the stop pins 25, 26 are drilled and the stop pins 25, 26 inserted into the extensions 27, 28 and fixed on the handle part 11.

Nunmehr wird der Federbalken 14 durch Druckausübung auf das Betätigungsteil 36 in Richtung des Pfeiles F in Fig. 1 im Uhrzeigersinn verschwenkt, wobei sich nach den Fig. 1, 4 und 4a die Ränder 21, 22 des Längsschlitzes 18 an die entsprechenden Anschlagflächen 19, 20 der Anschlagstifte 25, 26 anlegen, worauf der Längsschlitz 18 in Richtung der Pfeile 42, 43 in Fig. 4a federnd aufgespreizt wird. Aufgrund der schalenartigen Ausbildung der Axialanschlagflächen 47, 48 bleibt dabei die axial formschlüssige Halterung des Federbalkens 14 am Griffteil 11 aufrechterhalten.The spring bar 14 is now pivoted clockwise by exerting pressure on the actuating part 36 in the direction of the arrow F in FIG. 1, the edges 21, 22 of the longitudinal slot 18 against the corresponding stop surfaces 19, 20 according to FIGS. 1, 4 and 4a the stop pins 25, 26 create, whereupon the longitudinal slot 18 in the direction of arrows 42, 43 in Fig. 4a is sprung open. Due to the shell-like design of the axial stop surfaces 47, 48, the axially positive mounting of the spring bar 14 on the handle part 11 is maintained.

Nunmehr kann das Klingenteil 12 mittels des Zapfens 41 am Griffteil 11 montiert werden. Wird dann anschließend der Federbalken 14 losgelassen, so zieht sich der Längsschlitz 18 aufgrund der federnden Rückstellkräfte wieder zusammen, so daß das Hakenteil 32 entweder in der ausgestellten Lage nach Fig. 1 in die Nut 32 einfällt oder sich federnd an einer am Ende des Klingenteils 12 vorgesehenen Nockenbahn 44 abstützt, die an der Nut 32 mündet. Aufgrund der erfindungsgemäßen Montage kann sich jedoch der Längsschlitz 18 in der eingerasteten Stellung des Hakenteils 31 in die Nut 32 nach Fig. 1 nicht mehr vollständig zusammenziehen, so daß eine gewisse federnde Einrastkraft auch in dem ausgestellten Zustand des Klingenteils 12 verbleibt.The blade part 12 can now be mounted on the handle part 11 by means of the pin 41. If the spring bar 14 is then released, the longitudinal slot 18 contracts again due to the resilient restoring forces, so that the hook part 32 either in 1 extends into the groove 32 or is resiliently supported on a cam track 44 provided at the end of the blade part 12, which ends at the groove 32. Due to the assembly according to the invention, however, the longitudinal slot 18 can no longer contract completely in the engaged position of the hook part 31 in the groove 32 according to FIG. 1, so that a certain resilient latching force also remains in the extended state of the blade part 12.

Das Klappmesser ist nunmehr gebrauchsfertig.The folding knife is now ready to use.

Soll es aus der in Fig. 1 dargestellten Lage eingeklappt werden, so wird relativ zum Griffteil 11 in Richtung des Pfeiles F eine Kraft auf den Federbalken 14 ausgeübt, worauf der Federbalken 14 unter Aufspreizen des Längsschlitzes 18 im Uhrzeigersinn um die Schwenkachse 15 verschwenkt wird und der Hakenteil 31 aus der Nut 32 herausgehoben wird. Anschließend kann das Klingenteil 12 dann eingeklappt werden, wobei das Hakenteil 31, nachdem die Kraft F wieder aufgehoben wurde, federnd an dem Abstütznocken 44 entlang gleitet, bis die Schneide 37 in den für sie im Griffteil 11 vorgesehenen schlitzartigen Unterbringungsraum 33 eingetreten ist. Das Klappmesser befindet sich nunmehr in der vollständig eingeklappten Position.If it is to be folded in from the position shown in FIG. 1, a force is exerted on the spring bar 14 relative to the handle part 11 in the direction of the arrow F, whereupon the spring bar 14 is pivoted clockwise about the pivot axis 15 while the longitudinal slot 18 is spread and the hook part 31 is lifted out of the groove 32. Then the blade part 12 can then be folded in, the hook part 31, after the force F has been released again, sliding along the support cam 44 until the cutting edge 37 has entered the slot-like accommodation space 33 provided for it in the handle part 11. The folding knife is now in the fully retracted position.

Bei dem Ausführungsbeispiel nach den Fig. 5 und 5a ist anstelle der beiden Anschlagstifte 25, 26 ein griffteilfester Anschlagsteg 23 mit sich in Längsrichtung des Federbalkens 14 erstreckenden länglichen Querschnitt vorgesehen, welcher in einer dazu komplementären Erweiterung 24 des Längsschlitzes 18 untergebracht ist. Hierdurch wird der Längsschlitz 18 in zwei Abschnitte 18a, 18b unterteilt, die wiederum am oberen bzw. unteren Ende der Erweiterung 24 derart münden, daß auch bei aufgespreiztem Zustand des Längsschlitzes 18 der Anschlagsteg 28 in Axialrichtung formschlüssig mit dem Federbalken 14 verbunden bleibt, indem hierfür Axialanschlagflächen 47, 48 am Federbalken 14 und Gegen-Anschlagflächen 49, 50 am Anschlagsteg 23 zur Verfügung stehen.In the embodiment according to FIGS. 5 and 5a, instead of the two stop pins 25, 26, a stop web 23 which is fixed to the handle part and has an elongated cross section extending in the longitudinal direction of the spring bar 14 is provided, which is accommodated in a complementary extension 24 of the longitudinal slot 18. As a result, the longitudinal slot 18 is divided into two sections 18a, 18b, which in turn at the top or lower end of the extension 24 open in such a way that, even when the longitudinal slot 18 is expanded, the stop bar 28 remains positively connected to the spring bar 14 in the axial direction, for this purpose by means of axial stop faces 47, 48 on the spring bar 14 and counter-stop faces 49, 50 on the stop bar 23 be available.

Bei der Ausführungsform nach den Fig. 5 und 5a sind die Anschlagflächen 19, 20 in den Fig. 5, 5a an der unteren Fläche des Anschlagsteges 23 ganz links bzw. an dessen oberer Fläche ganz rechts vorgesehen. Sie arbeiten dort bei einer Verschwenkung des Federbalkens 14 im Uhrzeigersinn um die zentral vorgesehene Schwenkachse 15 mit den gegenüberliegenden Rändern 21, 22 der Erweiterung 24 des Längsschlitzes 18 zusammen.In the embodiment according to FIGS. 5 and 5a, the stop faces 19, 20 in FIGS. 5, 5a are provided on the lower surface of the stop web 23 on the far left or on its upper surface on the far right. They work there when the spring bar 14 is pivoted clockwise about the centrally provided pivot axis 15 with the opposite edges 21, 22 of the extension 24 of the longitudinal slot 18.

Wichtig ist, daß von den Anschlagflächen 19, 20 aus der Längsschlitz 18 sich noch nach beiden Seiten um ein erhebliches Stück innerhalb des Federbalkens 14 erstreckt. Der axiale Abstand der Anschlagflächen 19, 20 beträgt vorzugsweise etwa 10 bis 30, insbesondere etwa 20 % der Gesamtlänge des Längsschlitzes 18. Absolut liegt der axiale Abstand der Anschlagflächen 19, 20 bei 1 cm, während die Gesamtlänge des Längsschlitzes 18 4 bis 6 und insbesondere etwa 5 cm beträgt.It is important that the stop surfaces 19, 20 extend from the longitudinal slot 18 to a considerable distance within the spring beam 14 on both sides. The axial distance between the stop faces 19, 20 is preferably about 10 to 30, in particular about 20% of the total length of the longitudinal slot 18. In absolute terms, the axial distance between the stop faces 19, 20 is 1 cm, while the total length of the longitudinal slot 18 is 4 to 6 and in particular is about 5 cm.

Die Dicke des Federbalkens 14 entspricht der des Federbalkens üblicher Klappmesser und liegt bei etwa 2 bis 3 mm.The thickness of the spring bar 14 corresponds to that of the spring bar of conventional folding knives and is approximately 2 to 3 mm.

Das Griffteil 11 besteht im wesentlichen aus Metall, wobei jedoch aus Kunststoff oder Holz bestehende Einlagen 45 (Fig. 2, 3) vorgesehen sein können, die mittels Schrauben 46 am Griffteil 11 befestigt sind.The handle part 11 consists essentially of metal, but inserts 45 (FIGS. 2, 3) made of plastic or wood can be provided, which are fastened to the handle part 11 by means of screws 46.

In den Fig. 4, 4a, 5, 5a ist der Übersichtlichkeit halber zwischen den Bauelementen 23, 25, 26, 29 einerseits und den umgebenden Berandungen des Längsschlitzes 18 andererseits ein Spalt gezeigt, der jedoch tatsächlich nicht vorhanden ist, da die oberen und unteren Berandungen vorzugsweise mit Vorspannung, die vorderen und hinteren Berandungen vorzugsweise ohne Vorspannung an den betreffenden Bauelementen anliegen sollen.4, 4a, 5, 5a, for the sake of clarity, a gap is shown between the components 23, 25, 26, 29 on the one hand and the surrounding edges of the longitudinal slot 18 on the other hand, but this gap is actually not present since the upper and lower ones Boundaries preferably with a preload, the front and rear boundaries should preferably rest against the components in question without a preload.
