<p>The mounting assembly, for fixing a bell to a telephone's base plate, avoids play arising from production tolerances and thereby prevents small movements in the bell and mounting assembly. The surfaces of the hooks at the ends of the springy locking arms (3) are shaped so that the arms spring forces constantly press the bell assembly's support plate (1) against stops (11). The hooks interact with springy flaps via the aforementioned surfaces.</p> |
