  • Alarm clock having means for bridging two circular conducting paths via an adjustable contact means thereby causing generation of an acoustic alarm system
    Patent number: 4922475
    Abstract: Through an opening (2) in a dial (1), the hub (3) of a follower disc (4) extends. Placed on the end of the hub (3) is an alarm-setting hand (6) for reading the alarm time. The hub (3) is traversed by an hour-wheel pipe (7) which has two flattened side surfaces (23) for rotation-tight connection to a sliding wheel (12). A printed circuit board (14) is disposed adjacent to the hour-wheel (8) and has an opening (15) through which the hour-wheel pipe (7) extends. Two circular conductor paths (17, 18) disposed concentrically with the hour-wheel pipe (7) are applied to the printed circuit board (14). Between the sliding wheel (12) and the printed circuit board (14), an alarm-setting wheel (13) is rotatably disposed. The sliding wheel (12) has a recess (24) in which a contact bridge (26) is disposed.
