Abstract

Angegeben wird eine reibungsarme und präzise auslösende Flügelmechanik mit einem Hebeglied (1), das mit einem Hebegliedsattel (2) auf einer Pilote (3) eines Tastenhebels (4) aufliegt und an dem ein Repetierschenkel (5) sowie eine Stoßzunge (6) schwenkbar gelagert sind, deren Oberende (7) in eine durchgehende Repetierschenkelöffnung (8) in dem Repetierschenkel (5) hineinragt und deren Unterende (18) gegenüber einer Auslösepuppe (20) angeordnet ist, einer Repetierfeder (9), die mit ihrem unteren Federschenkel (10) auf das Unterende (11) der Stoßzunge (6) und mit ihrem oberen Federschenkel (12) auf den Repetierschenkel (5) drückt, sowie mit einem Hammerstiel (13), an dem sowohl eine um die eigene Achse drehbar gelagerte Hammerrolle (14) angeordnet ist, die auf dem Repetierschenkel (5) ruht und dem Oberende (7) der Stoßzunge (6) gegenüberliegt, als auch eine Hammerkapsel (15) angebracht ist, an der gegenüber einem Ende (16) des Repetierschenkels (5) eine Abknickschraube (17) angeordnet ist. Die Besonderheit der Flügelmechanik besteht darin, daß der obere Federschenkel (12) der Repetierfeder (9) an einer Repetierfederaufnahmerolle (21) anliegt, die an dem Repetierschenkel (5) befestigt und um die eigene Achse (22) drehbar gelagert ist.

Disclosed is a low-friction and precisely triggering wing mechanism with a lifting member (1) which rests with a lifting caliper (2) on a pilot (3) of a key lever (4) and on which a Repetierschenkel (5) and a jack (6) pivotally mounted are whose upper end (7) in a continuous Repetierschenkelöffnung (8) in the Repetierschenkel (5) protrudes and whose lower end (18) opposite a release button (20) is arranged, a Repetierfeder (9) with its lower spring leg (10) on the lower end (11) of the jack (6) and with its upper spring leg (12) on the Repetierschenkel (5) presses, and with a hammer handle (13) arranged on both a rotatably mounted about its own axis hammer roller (14) which rests on the Repetierschenkel (5) and the upper end (7) of the jack (6) opposite, as well as a hammer capsule (15) is attached to the opposite one end (16) of the Repetierschenkels (5) a kinking screw (17 ) at is ordered. The peculiarity of the wing mechanism is that the upper spring leg (12) of the Repetierfeder (9) on a Repetierfederaufnahmerolle (21) is applied, which is attached to the Repetierschenkel (5) and rotatably mounted about its own axis (22).
