Die Erfindung betrifft ein Taschenmesser mit mehreren Werkzeugen, die zwischen zwei Griffschalen ausschwenkbar gelagert sind und zu denen ein gewendelter Korkenzieher gehört. Solche Taschenmesser sind in zahlreichen Ausführungen bekannt. Um das Taschenmesser vielseitig verwendbar zu machen, bringt man zahlreiche Werkzeuge zwischen den Griffschalen unter. Mit der Zahl der Werkzeuge wachsen jedoch auch der Abstand zwischen den Griffschalen und damit die Breite und das Gewicht des Taschenmessers. Deshalb ist die Zahl der Werkzeuge, die man in einem solchen Taschenmesser unterbringen kann, begrenzt. The invention relates to a pocket knife with a plurality of tools which are pivotally mounted between two handle shells and which includes a coiled corkscrew. Such pocket knives are known in numerous designs. In order to make the pocket knife versatile, numerous tools are placed between the handles. However, with the number of tools, the distance between the handle scales and thus the width and weight of the pocket knife also increase. Therefore, the number of tools that can be accommodated in such a pocket knife is limited.

Bei solchen Taschenmessern ist es auch bekannt, den üblichen Schraubenziehern entsprechende Werkzeuge ausschwenkbar zwischen den Griffschalen unterzubringen. Für kleine Schrauben, wie sie in Uhren oder feinmechanischen Instrumenten und Geräten vorkommen, kann man diese Schraubenzieher jedoch nicht verwenden, weil sie sich nicht vom Taschenmesser lösen lassen und zusammen mit dem Taschenmesser schwierig und nicht mit der erforderlichen Genauigkeit und Sicherheit zu handhaben sind. In the case of pocket knives of this type, it is also known to pivotally accommodate tools corresponding to the conventional screwdrivers between the handle shells. However, these screwdrivers cannot be used for small screws, such as those found in watches or precision mechanical instruments and devices, because they cannot be detached from the pocket knife and are difficult to handle with the pocket knife and cannot be handled with the required accuracy and safety.

Es besteht deshalb die Aufgabe, solche Schraubenzieher für kleine Schrauben im Taschenmesser so unterzubringen, dass sie keinen zusätzlichen Platz beanspruchen und unabhängig vom schweren Taschenmesser nur mit nvei Fingern zu handhaben sind. It is therefore the task of accommodating such screwdrivers for small screws in the pocket knife in such a way that they do not take up any additional space and can only be handled with nvei fingers, regardless of the heavy pocket knife.

Die Erfindung löst die Aufgabe dadurch, dass ein aus Heft und Klinge bestehender Schraubenzieher für kleine Schrauben mittels einer am rundzylindrischen Heft vorgesehenen Gewinderille in die Wendel des Korkenziehers eingeschraubt und herausgedreht selbständig verwendbar ist. Diese Lösung vermeidet jeden zusätzlichen Platzbedarf und damit eine Verdickung des Taschenmessers. The invention solves the problem in that a screwdriver consisting of a handle and a blade for small screws can be screwed into the helix of the corkscrew by means of a thread groove provided on the round cylindrical handle and can be unscrewed and used independently. This solution avoids any additional space requirement and thus a thickening of the pocket knife.

Die empfindliche Klinge des kleinen Schraubenziehers ist in der massiven Wendel des Korkenziehers wie in einem Schutzkorb sicher und verbiegungsfrei untergebracht. Bei Bedarf wird der kleine Schraubenzieher aus dem ausgeschwenkten Korkenzieher herausgeschraubt und lässt sich dann unabhängig vom Taschenmesser mit zwei Fingern mit gutem Gefühl beim Lösen oder Anziehen empfindlicher kleiner Schrauben handhaben. The delicate blade of the small screwdriver is housed in the solid spiral of the corkscrew in a protective basket, safely and without bending. If necessary, the small screwdriver is unscrewed from the swung-out corkscrew and can then be handled with two fingers, regardless of the pocket knife, with a good feeling when loosening or tightening sensitive small screws.

Der Schraubenzieher besteht in bekannter Weise aus Heft und Klinge. Dabei ist das Heft rundzylindrisch und hat am Umfang eine mit der Wendel des Korkenziehers korrespondierende, schraubenförmige Gewinderille mit vorzugsweise U-förmigem Querschnitt eingeformt. Mit Hilfe dieser Gewinderille kann der Schraubenzieher mit der Klinge voran in den Korkenzieher eingeschraubt werden. Das verhältnismässig dicke Heft erlaubt eine sichere Führung des Schraubenziehers. Die Gewinderille verbessert die Griffigkeit des Heftes. The screwdriver consists of a handle and a blade in a known manner. The booklet is round-cylindrical and has a screw-shaped thread groove on the circumference corresponding to the helix of the corkscrew, preferably with a U-shaped cross section. With the help of this thread groove, the screwdriver can be screwed into the corkscrew with the blade first. The relatively thick handle allows the screwdriver to be guided safely. The thread groove improves the grip of the booklet.

Der Aussendurchmesser des rundzylindrischen Heftes wird zweckmässig gleich dem Aussendurchmesser der Wendel des Korkenziehers gewählt. Dadurch kann die Aussparung für den Korkenzieher in der Griffschale des Taschenmessers unverändert bleiben. Ausserdem kann man den Korkenzieher mit dem eingedrehten Schraubenzieher leicht ausschwenken, weil das Heft des Schraubenziehers und die Wendel des Korkenziehers eine gemeinsame, bündige Rundfläche bilden, die mit dem Daumennagel leicht zu fassen ist. The outside diameter of the round cylindrical handle is expediently chosen to be the same as the outside diameter of the spiral of the corkscrew. This allows the recess for the corkscrew in the handle of the pocket knife to remain unchanged. In addition, you can easily swing out the corkscrew with the screwdriver screwed in, because the handle of the screwdriver and the spiral of the corkscrew form a common, flush, round surface that is easy to grasp with the thumbnail.

Damit der kleine Schraubenzieher im Korkenzieher gut sitzt und ein zu tiefes Eindrehen des Schraubenziehers in die Wendel des Korkenziehers mit einem daraus möglichen Schaden für die Klinge verhindert wird, kann der in das freie Ende der Wendel des Korkenziehers greifende letzte Abschnitt der Gewinderille etwas verengt sein. Die Wendel des Korkenziehers und die Gewinderille des Schraubenziehers wirken dann nach dem Eindrehen des Schraubenziehers selbstsperrend und stellen den Schraubenzieher in der gewünschten Lage im Korkenzieher fest. So that the small screwdriver sits well in the corkscrew and prevents the screwdriver from being screwed too deeply into the helix of the corkscrew with possible damage to the blade, the last section of the thread groove which engages in the free end of the helix of the corkscrew can be somewhat narrowed. The helix of the corkscrew and the thread groove of the screwdriver then have a self-locking effect after the screwdriver has been screwed in and fix the screwdriver in the desired position in the corkscrew.

Die Klinge des kleinen Schraubenziehers besteht vorzugsweise aus hochwertigem Stahl. Das zylindrische Heft mit der Gewinderille wird vorzugsweise um die Klinge durch Spritzguss aus Kunststoff angeformt. Solche Schraubenzieher sind leicht und mit der erforderlichen Genauigkeit herzustellen und haben geringes Gewicht. The blade of the small screwdriver is preferably made of high quality steel. The cylindrical handle with the thread groove is preferably molded around the blade by injection molding from plastic. Such screwdrivers are easy to manufacture and with the required accuracy and are light in weight.

Derartige Schraubenzieher für Kleinschrauben lassen sich auch in jedes andere Taschenmesser eingliedern, das einen Korkenzieher mit einer zum Heft des Schraubenziehers passenden Wendel hat. Such screwdrivers for small screws can also be incorporated into any other pocket knife that has a corkscrew with a helix that matches the handle of the screwdriver.

Die Zeichnung bringt ein Ausführungsbeispiel für das Taschenmesser mit in den Korkenzieher eindrehbarem Schraubenzieher. The drawing shows an embodiment of the pocket knife with a screwdriver that can be screwed into the corkscrew.

In der Zeichnung zeigen: Fig. 1 das Taschenmesser in Draufsicht im eingeschwenktem Korkenzieher und dem Schraubenzieher darin; Fig. 2 eine Draufsicht wie Fig. 1, jedoch mit ausgeschwenktem Korkenzieher, aus dem der Schraubenzieher herausgedreht ist und Fig. 3 eine Seitenansicht des Schraubenziehers vergrössert. The drawing shows: Figure 1 shows the pocket knife in plan view in the pivoted corkscrew and the screwdriver therein. Fig. 2 is a plan view like FIG. 1, but with the corkscrew swung out, from which the screwdriver is unscrewed and Fig. 3 is an enlarged side view of the screwdriver.

Laut Fig. 1 hat das Taschenmesser 1 neben anderen bekannten Werkzeugen, z. B. Messern, Dosenöffner usw. zwischen den Griffschalen 2 auch einen Korkenzieher 3 ausschwenkbar gelagert, der eine Wendel 4 aus Rundstahl hat. 1 has the pocket knife 1 in addition to other known tools such. B. knives, can opener, etc. between the handle shells 2, a corkscrew 3 is also pivoted out and has a helix 4 made of round steel.

In der Ruhestellung sitzt dieser Korkenzieher 3 in bekannter Weise in der Aussparung 5 der Griffschale 2. In den Korkenzieher 3 ist der aus Klinge 6 und Heft 7 bestehende Schraubenzieher 8 mit der Klinge voran eingedreht, so dass es gemäss Fig. 1 ganz in der Wendel 4 untergebracht ist und dann mit dem Korkenzieher 3 zwischen die Griffschalen 2 zurückgeschwenkt werden kann. Das Heft 7 des Schraubenziehers 8 ist rundzylindrisch und hat am Umfang eine schraubenförmige Gewinderille 9 von U-förmigem Querschnitt, deren Steigung der Wendel 4 entspricht, so dass der Schraubenzieher 8 mit dem Heft in die Wendel 4 eingeschraubt werden In the rest position, this corkscrew 3 is seated in the recess 5 of the grip shell 2 in a known manner. In the corkscrew 3, the screwdriver 8 consisting of blade 6 and handle 7 is screwed in with the blade first, so that it is completely in the spiral according to FIG. 1 4 is housed and can then be pivoted back with the corkscrew 3 between the handle scales 2. The handle 7 of the screwdriver 8 is round-cylindrical and has a helical thread groove 9 of U-shaped cross-section on the circumference, the pitch of which corresponds to the helix 4, so that the screwdriver 8 with the handle is screwed into the helix 4

kann. Der Querschnitt der Gewinderille 9 ist an dem Ende 10 des Heftes 7, das der Klinge 6 abgewendet ist, etwas verengt, so dass sich der Schraubenzieher 8, sobald er ganz in den Korkenzieher 3 eingedreht ist, in der Wendel 4 festklemmt und nicht mehr tiefer im Korkenzieher versenkt werden kann. Diese Sperre lässt sich beim Herausdrehen des Schraubenziehers 8 aus dem Korkenzieher 3 durch Fingerdruck leicht überwinden. can. The cross section of the thread groove 9 is somewhat narrowed at the end 10 of the handle 7, which faces away from the blade 6, so that the screwdriver 8, as soon as it is fully screwed into the corkscrew 3, clamps in the helix 4 and no longer can be sunk in the corkscrew. This lock can be easily overcome by unscrewing the screwdriver 8 from the corkscrew 3 by finger pressure.

Der Aussendurchmesser des Heftes 7 ist im Beispiel gleich dem Aussendurchmesser der Wendel 4, so dass Wendel 4 und Heft 7 eine bündige Grifffläche bilden, die das Ausschwenken des Korkenziehers 3 erleichtert. In the example, the outside diameter of the booklet 7 is equal to the outside diameter of the coil 4, so that the coil 4 and booklet 7 form a flush gripping surface which facilitates the pivoting out of the corkscrew 3.
