Patent

CA 2402726

The knife (3; 4), in particular the so-called survival knife, is made into a multi-purpose tool by arranging the blade portion (3) of the knife (3; 4) to receive a wedged portion (1), provided e.g. with a hammer head (10), which forms a hatchet (1; 2) together with the cutting edge (2) of the blade portion (3). The blade portion (3) incorporates e.g. an oblong aperture (7), whereto the wedged portion (1) is locked with a fastener (5), in this case with a flat plate locking pin (5, 13). The locking pin (5; 13) also includes a spring pin (13), to ensure quick locking. The wedged portion (1) has in this case an integral deep groove-like fastener, adapted to be mounted on the back section (6) of the blade portion (3). The wedged portion (1) detached from the blade portion (3) is kept e.g. locked in the handle portion (4; 11) of the knife.

L'invention concerne un couteau (3, 4), en particulier un couteau de survie, constitué d'un outil à usages multiples comprenant une partie lame (3) de couteau destinée à recevoir une partie conique (1) pourvue d'une tête de marteau (10), et formant une hachette avec le bord de coupe de ladite partie lame (3). Cette partie (3) possède, par exemple, une ouverture oblongue (7) dans laquelle on verrouille la partie conique à l'aide d'un élément de fixation (5), notamment à l'aide d'une tige de verrouillage (5, 13). Ladite tige de verrouillage (5, 13) comprend également une tige à ressort (13) assurant un verrouillage rapide. La partie conique (1) comprend notamment un élément de fixation d'une seule pièce du type rainure profonde, conçu de façon à être monté sur la partie supérieure (6) de la partie lame (3). Ladite partie conique (1) détachée de la partie lame (3) est, par exemple, enfermée dans la partie manche (4, 11) du couteau.
