Description

Die Erfindung bezieht.sich auf ein Messer mit hohlem Schaft und Feststellvorrichtung für die bewegliche Messerklinge.The invention relates to a knife with a hollow shaft and locking device for the movable knife blade.

Die Erfindung bezweckt, ein Messer der vorangehend genannten Art zu verbessern, bei welchem die Messerklinge im ausgefahrenen Zustand einen besonders festen Halt im Schaft hat. Erreicht wird dies durch ein Messer gemäß den Patentansprüchen..The invention aims to improve a knife of the aforementioned type, in which the knife blade has a particularly firm hold in the shaft in the extended state. This is achieved by a knife according to the patent claims.

Gemäß der Erfindung ist die Messerklinge mit einem Schieber gelenkig verbunden, wobei der Schieber in der sog. 0°-Stellung der beiden Teile, der Aufbewahrungslage des Messers im Schaft, sicherstellt, daß das Messer nicht ohne weiteres aus dem Schaft herausfallen kann. In der gestreckten Lage zwischen Schieber und Messerklinge, befindet sich das Messer in der ausgefahrenen Lage.,: wobei der Schieber selbst am Schaft fest gehaltertist, so daß die Messerklinge einen außergewöhnlich guten Halt hat. Bei einer Ausbildung des Messers als Mehrzweckmesser ist eine weitere Öffnung im Schaft vorgesehen, durch welche ein Kapselheber oder irgendein anderes geeignetes Werkzeug ein- und ausgefahren werden kann. Gemäß der Erfindung kann hierbei das Gelenk zwischen Schieber und Messerklinge dazu dienen, den Zusatzteil in seiner ausgefahrenen Lage zu haltern.According to the invention, the knife blade is articulated with a slide, the slide in the so-called. 0 ° position of the two parts, the storage position of the knife in the shaft, ensures that the knife can not easily fall out of the shaft. In the stretched position between the slide and knife blade, the knife is in the extended position.,: The slide itself being held firmly on the shaft, so that the knife blade has an exceptionally good hold. If the knife is designed as a multi-purpose knife, a further opening is provided in the shaft, through which a bottle opener or any other suitable tool can be moved in and out. According to the invention, the joint between slide and knife blade can serve to hold the additional part in its extended position.

Die Erfindung wird nachstehend anhand der Zeichnung beispielsweise erläutert.The invention is explained below with reference to the drawing, for example.

Es zeigen

  • Fig. 1 eine Draufsicht auf das Messer gemäß der Erfindung, wobei die Klinge ausgefahren ist,
  • Fig. 2 eine entsprechende Draufsicht, in der die Klinge jedoch eingefahren und ein Kapselheber ausgefahren ist,
  • Fig: 3 eine Schnittansicht gemäß III-III der Fig. 2.
Show it
  • 1 is a plan view of the knife according to the invention, with the blade extended,
  • 2 is a corresponding top view, but in which the blade is retracted and a bottle opener is extended,
  • 3 shows a sectional view according to III-III of FIG. 2.

In den Fig. ist mit 10 ein Schaft bezeichnet, der gemeinhin bei Messern bekannt ist. Es handelt sich hierbei um einen Hohlkörper, der beispielsweise aus einem Spritzkunststoff hergestellt werden kann. Der Schaft 10 hat eine längliche, vorzugsweise quaderartige Form mit Abrundungen. Er besitzt im Inneren einen Hohlraum, von dem her Öffnungxnach außen führen. Eine der großen Flächen ist nach oben__hin durch eine im wesentlichen rechteckförmige Öffnung 11 geöffnet, während an den kleinen, den Stirnseiten des Schaftes Öffnungen 12 und 13 vorgesehen sind.In the figures, 10 denotes a shaft, which is commonly known in knives. It is a hollow body that can be made, for example, from a molded plastic. The shaft 10 has an elongated, preferably cuboid shape with rounded portions. It has a cavity inside, from which openings x lead outwards. One of the large surfaces is opened upwards through a substantially rectangular opening 11, while openings 12 and 13 are provided on the small, front sides of the shaft.

Die Öffnung 11 ist mit Erweiterungen an den beiden Enden und im Bereich zwischen den beiden Enden ausgebildet. Diese Ausnehmungen tragen die Bezugszahlen 14, 15 und 16.The opening 11 is formed with extensions at the two ends and in the area between the two ends. These recesses have the reference numbers 14, 15 and 16.

Eine Messerklinge 20 in der üblichen Art und Weise ist an ihrem der Spitze gegenüberliegenden Ende mit einem Gelenk 21 mit einem Schieber 22 verbunden. Das Gelenk ermöglicht, daß die beiden Teile 20 und 22 in eine zueinander gestreckte Lage, aber auch in eine Lage gebracht werden können, in der sie aufeinanderliegen.A knife blade 20 in the usual manner is connected at its end opposite the tip to a joint 21 with a slide 22. The joint enables the two parts 20 and 22 to be brought into an extended position, but also into a position in which they lie one on top of the other.

Der Schieber 22 kann ebenfalls,wie das Messer 20, aus Metall, aber auch aus einem Kunststoff bestehen und hat die Form eines flachen Quaders mit einer Dicke von etwa 1 mm.The slider 22, like the knife 20, can also consist of metal, but also of a plastic and has the shape of a flat cuboid with a thickness of approximately 1 mm.

Am freien Ende des Schiebers 22 befindet sich ein Rastteil 23. Der Rastteil 23 und auch das Gelenk 21 sind so ausgebildet, daß diese Teile in die Ausnehmungen 14, 15 und 16 eingeführt werden können, so daß eine Rastlage dieser Funktionsteile entsteht.At the free end of the slide 22 there is a locking part 23. The locking part 23 and the joint 21 are designed so that these parts can be inserted into the recesses 14, 15 and 16, so that a locking position of these functional parts is created.

Die Messerklinge 20 kann durch die Öffnung 12 ein- und ausgefahren werden, während ein Kapselheberteil 20 durch die Öffnungen 13 ein- und ausgefahren werden kann.The knife blade 20 can be moved in and out through the opening 12, while a bottle opener part 20 can be moved in and out through the openings 13.

In der Fig. 1, der Gebrauchslage, ist das Gelenk 21 in der Ausnehmung 16 angeordnet, währen der Rastteil 23 sich in der Ausnehmung 15 befindet.In Fig. 1, the position of use, the joint 21 is arranged in the recess 16, while the locking part 23 is located in the recess 15.

In.der in Fig. 2 gezeigten Lage befindet sich der Rastteil 23 im Inneren des Schaftes 10, und zwar unterhalb der Öffnung 11. Das Gelenk 21 befindet sich in der Ausnehmung 14. Aus Fig, 3 ist zu ersehen, daß das Gelenk 21 so ausgebildet ist, daß es in Berührungslage mit dem Kapselheber 30 angeordnet ist. Auf diese Art und Weise kann gemäß Fig. 3 erreicht werden, daß der Rastteil 30 in seiner Arbeitslage befestigt ist.In the position shown in FIG. 2, the latching part 23 is located inside the shaft 10, specifically below the opening 11. The joint 21 is in the recess 14. From FIG. 3 it can be seen that the joint 21 is so is formed that it is arranged in contact with the bottle opener 30. In this way it can be achieved according to FIG. 3 that the locking part 30 is fixed in its working position.

Würde man, ausgehend von der Lage der Teile nach Fig. 3, sowohl den Schieber 22 als auch die Klinge 20 nach rechts verschieben, so könnte das Gelenk 21 in die Ausnehmung 15 und der Rastteil 23 in die Ausnehmung 11 gebracht werden. Auch in dieser Lage befindet sich die Messerklinge 20 im Schaft 10. In dieser Lage kann der Kapselheber 30 eingefahren werden, so daß keines der Funktionsteile über die äußeren Umrisse des Schaftes 10 vorsteht.If, starting from the position of the parts according to FIG. 3, both the slide 22 and the blade 20 were to be moved to the right, the joint 21 could be brought into the recess 15 and the latching part 23 into the recess 11. In this position too, the knife blade 20 is located in the shaft 10. In this position, the bottle opener 30 can be retracted so that none of the functional parts protrude beyond the outer contours of the shaft 10.
