Abstract

PURPOSE: To inexpensively provide an ornament-driving device of a gimmick clock or the like which has simple constitution and lessened failure. CONSTITUTION: A driving device is attached to a hollow cylindrical fixed permanent magnet 6 through an attached plate 5 in a case 1. A movable permanent magnet 8 which has substantially the same length as the magnet 6 and whose magnet poles of both ends are different therefrom is movably engaged in its hollow part 6a. A drive rod 9 is projected on both the ends of the movable permanent magnet 8, and drive permanent magnets 10 are fixed on each edge 9a of the drive rod. A pair of drive coils 4 are provided forward each drive permanent magnet. Movable members 11 are attached to each projection end 9a of the drive rod 9, and an ornament 2 provided outward the case is movably provided. When excitation is performed so as to alternatingly make the left-hand and right-hand drive coils 4 an opposite pole, attraction and repulsion force is produced between the drive permanent magnet 10 and the coil 4, and the movable member 11 reciprocates and moves against the attraction force between the fixed permanent magnet 6 and the movable permanent magnet 8.

The function is to position the magnetic poles at both ends of a hollow cylindrical fixed permanent magnet and a movable permanent magnet that is movably provided in the hollow portion of the fixed permanent magnet and has substantially the same length as the fixed permanent magnet. Therefore, when an external force is applied to the movable permanent magnet to displace it, the movable permanent magnet moves so as to return to the original position, and due to the inertial force, it projects to the opposite side to perform a simple vibration damping motion. The drive permanent magnet fixed to each tip of the drive rod integrated with the movable permanent magnet repeats absorption and repulsion due to a change in the polarity of the voltage applied to the pair of drive coils to give energy to the drive rod. The decoration that moves integrally with the drive rod repeats reciprocating movement due to the magnetic absorption and repulsion forces alternately acting.

Next, the operation will be described. When no voltage is applied to the drive coils 4 and 4, that is, in a neutral state, the magnetic poles at both ends of the fixed permanent magnet 6 and the movable permanent magnet 8 are different, so that both ends are mutually opposite. They are attracted to each other and are still at the closest position. In this state, when the drive rod 9 is pulled out against the attraction force of both magnets 6 and 8 and then released, the drive rod 9 immediately returns to the original position by the attraction force. When the drive rod 9 returns to the original position, the drive rod 9, the movable member 11, the ornament 2, etc. are simultaneously moved together with the drive permanent magnet 10. However, since the movable member, the ornament, etc. have a large mass, the movable permanent magnet 8
Is projected to the opposite side of the fixed permanent magnet 6 by the inertial force. If left in this state, the drive rod 9
Is pulled back again by the attraction force of both magnets 6 and 8, and is similarly projected to the opposite side by the inertial force, and this reciprocating motion is repeated. Then, the amplitude of this reciprocating motion is attenuated and finally both ends of both magnets 6 and 8 stop at the position where they are closest.

The supplement of energy for the above-mentioned damped vibration is performed by applying a voltage to each drive coil 4, 4. That is, when a voltage is applied to each of the drive coils 4 and 4 and each tip thereof is excited to, for example, the N pole, if the right side of each of the drive permanent magnets 10 and 10 is magnetized to the S pole, the respective magnetic action causes An attractive force is generated between the drive coil 4 on the right side and the drive permanent magnet 10, and a repulsive force is generated between the drive coil and the drive coil because the tip of the drive permanent magnet on the left side is magnetized to the S pole. Both forces are combined to give kinetic energy to the drive rod 9 and the like. At this time, the drive rod 9 moves all the way to the right, and when the voltage application is stopped here, the drive coil moves to the fixed permanent magnet 6 and the movable permanent magnet 8.
It moves to the left by the suction force between and, and projects to the opposite side by the inertial force.
