Description

[Detailed description of the invention] The present invention relates to the improvement of a decorative pendulum device attached to a watch, and in particular, when one of a plurality of pendulums is oscillated at a predetermined period, other pendulums are is capable of swinging at a predetermined period, and is characterized in that at least the swinging directions of the driving pendulum and the driven pendulum are reliably different.

Conventionally, in a decorative pendulum device for a clock, the pendulum is 1
There is only one pendulum, and a configuration is known in which this one pendulum swings left and right at a predetermined period. This type of device lacks freshness in its dynamic decorative effect and lacks interest in design.

In recent years, there has been an increasing demand for watches equipped with decorative pendulum devices as interior decorations, and it has been desired to provide a decorative pendulum device that has a novel dynamic decorative effect.

The present invention was developed in view of the above-mentioned conventional problems, and its purpose is to enable a plurality of swinging rods to swing at a predetermined period in conjunction with the swinging driving of one swinging rod. To ensure that at least the swinging directions of the driving side swinging rod and the driven side swinging rod are different, the period of the driven side swinging rod can be corrected as appropriate with respect to the period of the driving side swinging rod.

In order to achieve this object, the present invention includes a support member installed upright in the case, and at least two support members arranged on the support member at a predetermined distance in the longitudinal direction.
a transmission member that is pivotably supported at a substantially central position between the two support parts adjacent to each other and has a horizontal transmission arm; and a transmission member that is in contact with the transmission arm of the transmission member. at least two swinging parts integrally formed with swinging rods having swinging rod heads that are capable of swinging left and right with respect to the axis of the transmission member; and a predetermined swinging rod attached to the case. a swinging drive device capable of continuously swinging and driving the case with respect to the case; It is characterized in that the other swinging rods can be swung by being transmitted to the other swiveling parts via the rod head and the transmission member.

The present invention will be described below based on an embodiment of the present invention shown in the drawings.

FIG. 1 shows a sectional view of a timepiece equipped with a pendulum device according to the present invention, in which a support rod 4 as a support member is integrally erected on the back case 2 of the timepiece, and a timepiece mechanism body 6 is provided. It is installed. A front case 8 of the watch is provided with an indicator 10 for displaying the time, forming a dial 12. A through hole 14 is bored in the dial 12, and an indicator pipe 16 of the timepiece mechanism body 6 passes through the through hole 14. A pointer 18 is attached to the display pipe 16, and an appropriate time is displayed by rotating the display pipe 16 at a predetermined speed.

The support rod 4 has a large diameter support part 20 and a small diameter support part 22.
are formed, and a swinging part 24 and a swinging part 26 are pivotally supported on a part of the large-diameter support part 20 and a part of the small-diameter support part 22, respectively, so as to be freely swingable. A transmission member 28 is rotatably supported on the large-diameter support portion 20 of the support rod 4 at a substantially central position between the pivot position of the swing portion 24 and the pivot support position of the swing portion 26 . The transmission member 28 is formed with transmission arms 30 and 32 extending in the horizontal direction, and as shown in FIG. It is set so that it can come into contact with the rod head 36.

The swinging parts 24, 26 are formed in a cylindrical shape, and swinging rod heads 34, 36, swinging rods 38, 40, and swinging balls 42, 44 are integrally formed in each swinging part 24, 26. As shown in FIG. 3, curved portions 46 and 48 are formed in the vicinity of the display pipe 16 of the swinging rods 38 and 40 in a substantially semicircular shape. As a result, when the swinging rods 38, 40 are used for swinging, the display pipe 16 and the swinging rods 38, 40
will not collide.

A driving coil 50 is disposed in the clock mechanism body 6 to provide a rocking force to the swinging rod 40. A permanent magnet 52 to be coupled is fixed.

The illustrated embodiment is constructed as described above, and its effects will now be described. The solid line state in FIG. 4 is a state in which the swinging rods 38 and 40 are stationary, and when the drive coil 50 is operated in this state, the swinging rod 40 is moved due to the electromagnetic coupling between the drive coil 50 and the permanent magnet 52. When moving in the direction of arrow A, the swinging rod head 36 moves in the direction of arrow B as shown in FIG. At this time, the swinging rod head 36 presses and moves the transmission arm 32 in the direction of arrow B, which allows the transmission arm 30 to press and move the swinging rod head 34 in the direction of arrow A. Thereafter, the swinging rod 40 moves in the direction of the solid line in FIG. 4 due to the weight of the swinging ball 44 in FIG. 1, and is located in the state shown in FIG. 6. Thereafter, the swinging rod 40 continuously performs the well-known pendulum motion due to the inertial force due to the weight of the swinging ball 44 and the swing biasing force due to the electromagnetic force of the drive coil 50 and the permanent magnet 52.

On the other hand, after the swinging rod head 34 is moved by the transmission arm 30 to the position shown in FIG.
A pendulum movement is performed as in 4. FIG. 7 shows the engaged state of the swinging rod heads 34, 36 and the transmission arms 30, 32 in FIG. 6.

A characteristic feature of the present invention is that the swinging rod 40 on the main drive side is swung by a conventionally well-known swinging drive device, and the swinging rod head 36, which swings integrally with the swinging rod 40, is connected to the transmission arm 3 of the transmission member 28. The transmission member 28 is rotated by contacting the transmission arm 30 and the swinging rod head 34, and the swinging rod head 34 is moved in the opposite direction to the swinging rod head 36, and as a result, the swinging rod 38 is driven. It is to let Therefore, the swinging rod 38 and the swinging rod 40 can reliably swing in opposite directions,
The deviation of the natural vibration of each swinging rod 38, 40 is reliably corrected by the transmission member 28, and each swinging rod 38, 40
0 can perform pendulum motion with the same period.

In the illustrated embodiment, the swinging rod heads 34 and 36 are arranged above the swinging parts 24 and 26, and the swinging rod heads 3
A transmission member 28 is arranged so as to be able to come into contact with the transmission member 2 and 36, as shown in FIG.
8 can also be implemented by arranging the swing parts 8 below the swing parts 24 and 26. Further, in the embodiment shown in FIG. 1, the swinging parts 24 and 26 are pivotally supported by the support rod 4, but as shown in FIG. 9, a knife edge 60 is formed on the support part 58. , a structure in which a V-groove 64 is formed in the swinging portion 62 can also be implemented. Furthermore, in the embodiment shown in FIG.
4, 26 may be pivotally supported on the upper surface of the timepiece mechanism body 6. Furthermore, when the transmission arms 30 and 32 are made of elastic members, when the swinging rods 38 and 40 are swung in the same direction by an external force, the transmission arms 30 and 32 are elastically deformed appropriately. Twisting rod head 34,3
6 damage can be prevented.

As explained above, according to the present invention, a transmission member is provided which is swingably supported approximately at the center of the swinging portion of a plurality of pendulums, and the transmission member is swing-driven by a swing drive device. By transmitting the swinging motion of one swinging rod, other swinging rods can swing via the transmission member. In addition, by using the swinging motion of the transmission member, the driving side swinging rod and the driven side swinging rod can be reliably swung in opposite directions, which can improve the dynamic decorative effect of the interior. In addition, due to the swinging motion of the transmission member, the driven side swinging rod is corrected to be approximately the same as the swinging period of the driving side swinging rod, so the external size and design of the pendulums including the swinging balls can be configured to differ from each other. Even if this happens, the driving side swinging rod and the driven side swinging rod will surely swing in opposite directions.
