Abstract (en)
[origin: EP2320282A1] The mechanism has gongs (3-5), where each gong is fixed to a gong holder at one of its ends, where the holder is secured to a plate. Hammers are mounted on the plate for hitting each gong. A noise insulator arrangement formed of an insulating part (6) and a counter insulating part (7) insulates noise of the gong. The insulating part is fixed to be moved by a driving unit formed of a lever in a form of minute rack and levers (11, 12), so that a portion of the insulating part is close to the gong in a rest mode or at remote from the gong in a striking mode. The insulating part and counter-insulating parts are made of elastically deformable plastic materials.
