にして揺動させるようになつている。 A fulcrum receiving part 3 of the first pendulum 2 is provided in the upper part of the movement 1, and a swing rod 7 extending downward from a fulcrum shaft part 5 placed on the fulcrum receiving part 3 is connected. Swinging rod 7
A permanent magnet 9 is attached to the lower part of the permanent magnet 9.
A permanent magnet 9 is placed on the movement 1 near the oscillation trajectory of the
The electromagnetic coil 11 is installed facing the. Then, a pulse current is sent to the electromagnetic coil 11 from an electronic circuit (not shown), and the electromagnetic coil 11 and the permanent magnet 9
The swinging rod 7 is made to swing by using the fulcrum receiving part 3 as a fulcrum by the magnetic action of the fulcrum.

されないようにスリツプ結合手段が形成される。 The fulcrum shaft portion 5 extends close to the rear surface (left side in FIG. 1) of the movement 1, and has a lever portion 13 connected to its end. The lever portion 13 faces downward and is provided with a protruding piece 15 at its lower end, and this protruding piece 15 is engaged with a lever 27 to be described later. A support shaft 17 protrudes from the center of the rear surface of the cover of the movement 1, and a stepped tube 19 is rotatably fitted onto the support shaft 17.
The tubular body 19 is prevented from coming off by a snap spring 20 fitted to the support shaft 17. The upper part of the swing rod 23 of the second pendulum via a collar 21, a slip plate spring 25, and a lever 27 are rotatably and slidably attached to each step of the outer circumference of the tube body 19, and the support shaft 17, the tube body 19, and the collar are rotatably attached. 21, the slip leaf spring and the snap spring 20 constitute a slip coupling means. By changing the fitting position of the snap spring 20, the pressing state between the swinging rod 23, the slip leaf spring 25, and the lever 27 can be changed, and when there is a strong pressing state, the swinging of the lever part 13 pushes the slip leaf spring 25. The signal is transmitted to the swinging rod 23 via the swing rod 23. Further, when a load is applied to the swinging rod 23 of the second pendulum, a slip coupling means is formed so that the slip plate spring 25 and the lever 27 or the swinging rod 23 slip so that the load is not transmitted to the lever portion 13.

すれば、揺動方向が同じになる。 An elongated hole 29 is provided in the upper part of the lever 27, and the projecting piece 15 of the lever part 13 is slidably inserted into the elongated hole 29 in the longitudinal direction and engaged, thereby controlling the swinging of the swing rod 7 of the first pendulum to the second pendulum. The signal is transmitted to the swing rod 23 of the pendulum. In addition, in the above configuration, since the connection point between the lever part 13 and the lever 27 is located above the support shaft 17, the swing directions of the first pendulum and the second pendulum are opposite, but the connection point of the lever is positioned above the support shaft 17. If it is placed below the support shaft 17, the swinging directions will be the same.

スリツプ結合手段を介して第２振子の振竿２３が
揺動される。 Next, the operation of the dual pendulum device of the timepiece having the above configuration will be explained. The swinging rod 7 of the first pendulum is swung by a magnetic force acting between the swinging rod 7 and the permanent magnet 9 when a pulse current flows through the electromagnetic coil 11 . The swinging of the swinging rod 7 causes the lever portion 13 to swing via its fulcrum shaft 5, and further swings the swinging rod 23 of the second pendulum via a slip coupling means consisting of a slip leaf spring 25 and the like.

破損することはない。 When a load is applied to the swinging rod 23 of the second pendulum, such as by touching the swinging rod 23 with a hand, the lever 27 slips between the slip plate spring 25 and the swinging rod 23 or the lever 27, so that the load is applied to the swinging rod of the first pendulum. I don't work at 7. Therefore, even if the rod of the first pendulum is subjected to magnetic action, no force acts against the magnetic action, and the double pendulum device will not be damaged.

全性を確保することができる利点がある。(Effects of the invention) As described above, the present invention provides a slip coupling means in the connection part that transmits the swinging force from the first pendulum to the second pendulum, so even if a load is applied to the swinging rod of the second pendulum, the slip coupling means is provided. There is an advantage that the continuous pendulum device will not be damaged and the safety of the device can be ensured.
