Description
Taschenmesser mit einer sich selbsttätig öffnenden Klinge. Den Gegenstand der vorliegenden Erfindung bildet ein Taschenmesser, das infolge Auslösens einer unter Federdruck stehenden und durch Zahnradübertragung mit der Klinge in Verbindung gebrachten Zahnstange selbsttätig geöffnet wird.Pocket knife with an automatically opening blade. The subject of the present invention forms a pocket knife which, as a result of triggering a under spring pressure and connected to the blade by gear transmission brought rack is opened automatically.
Die Erfindung besteht in der besonderen Anordnung des Getriebes, durch das eine gedrängte Bauart geschaffen wird.The invention consists in the special arrangement of the transmission through that a compact design is created.
Wie die Zeichnung ersichtlich macht, ist an der Klingendrehscheibe ein Zahnrad i befestigt, welches in ein Zahnrad 2 eingreift. Mit diesem dreht sich ein kleineres Zahnrad, das in die Zahnstange 3 eingreift, welche unter Wirkung der Schraubenfeder q. von einem Lager 3 verschiebbar gehalten wird und mit zwei Rasten 6, 7 versehen ist. In die Rast 7 (Abb. 2) greift eine federnde Sperrnase 8, welche mit einem den Messergriff durchgreifenden Druckknopf g in Verbindung gebracht ist.As the drawing shows, is on the blade turntable a gear i is attached, which meshes with a gear 2. With this rotates a smaller gear that engages the rack 3, which under the action of Coil spring q. is held displaceably by a bearing 3 and with two notches 6, 7 is provided. In the catch 7 (Fig. 2) engages a resilient locking lug 8, which is associated with a push button g which extends through the knife handle.
Durch einfaches Niederdrücken des Knopfes g in Pfeilrichtung A tritt die Nase 8 aus der Rast 7, und es läßt sich so die Messerklinge in Pfeilrichtung B einlegen, wobei infolge der Zahnradübertragung 2, i die Zahnstange 3 entgegen der Wirkung der Schraubenfeder q. in Pfeilrichtung C zurückgedrückt wird, wonach die Sperrnase 8 in die Rast 6 einspringt und so das selbsttätige Öffnen der Messerklinge sichert. Nach einfachem Niederdrücken des Knopfes g gibt die Sperrnase 8 die Zahnstange 3 wieder frei, welche dann von der Schraubenfeder q. vorgestoßen wird. Infolge der Zahnradumdrehung wird die Klinge gestreckt und durch Einspringen der Sperrnase 8 in die Rast 7 mit dem Griff starr gemacht.Simply press button g in the direction of arrow A. the nose 8 from the detent 7, and it can be the knife blade in the direction of the arrow B insert, whereby due to the gear transmission 2, i the rack 3 opposite the action of the coil spring q. is pushed back in the direction of arrow C, after which the locking lug 8 jumps into the detent 6 and so the automatic opening of the knife blade secures. After simply pressing the button g, the locking lug 8 is the rack 3 free again, which is then relieved by the helical spring q. is advanced. As a result of Rotation of the gear, the blade is stretched and the locking lug 8 made rigid in the detent 7 with the handle.
Abb. i zeigt das geöffnete Messer bei abgenommener Heftschale, Abb. 2 eine Seitenansicht, Abb. 3 das Einknicken der Klinge.Fig. I shows the open knife with the handle removed, Fig. 2 a side view, Fig. 3 the buckling of the blade.
