Abstract

Bei einem Messer (10) ist der Betätigungsbereich von einem relativ zum Klingenträger (15) beweglichen gesonderten Betätigungsteil (27) gebildet, welches entgegen der Ausfahrbewegung (bei x) des Klingenträgers (15) mit einer gesonderten Rückstellkraft (bei 38) belastet ist. Klingenträger (15) und Betätigungsteil (27) sind in ihrer Ausgangsposition (A) durch ein primäres Kupplungselement (P) des Betätigungsteils (27) und durch ein korrespondierendes sekundäres Kupplungselement (S) des Klingenträgers (15) nur im Ausfahrsinne (bei x) des Klingenträgers (15) auf Mitnahme bewegungsgekuppelt. Im Einfahrsinne (bei z) des Klingenträgers (15) jedoch befinden sich primäres Kupplungselement (P) und sekundäres Kupplunselement (S) außer Eingriff miteinander. Die Bewegung (bei a) des Betätigungsteils (27) im Ausfahrsinne (bei x) des Klingenträgers (15) ist begrenzt. Dem Klingenträger (15) ist eine zusätzliche Relativbewegung (bei R) in Ausfahrrichtung (x) gestattet, welche das sekundäre Kupplungselement (S) des Klingenträgers (15) außer Eingriff mit dem primären Kupplungselement (P) des Betätigungsteils (27) versetzt.

Figure 00000001
In the case of a knife (10), the actuation area is formed by a separate actuation part (27) which is movable relative to the blade carrier (15) and which is loaded with a separate restoring force (at 38) against the extension movement (at x) of the blade carrier (15). Blade carrier (15) and actuating part (27) are in their starting position (A) by a primary coupling element (P) of the actuating part (27) and by a corresponding secondary coupling element (S) of the blade carrier (15) only in the sense of extension (at x) Blade carrier (15) motion-coupled to take along. In the entry direction (at z) of the blade carrier (15), however, the primary coupling element (P) and the secondary coupling element (S) are out of engagement with one another. The movement (at a) of the actuating part (27) in the direction of extension (at x) of the blade carrier (15) is limited. The blade carrier (15) is permitted an additional relative movement (at R) in the extension direction (x) which displaces the secondary coupling element (S) of the blade carrier (15) out of engagement with the primary coupling element (P) of the actuating part (27).
