Embodiments Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

FIG. 1 shows an outline of a full-body swing clock to which the present invention is applied.

In FIG. 1, a watch body 10 supported so as to be able to freely swing about a pendulum fulcrum has a time display section 12 on its upper part, and a pendulum 14 that swings together with the time display section 12 on its lower part. And the pendulum 14 is the swinging rod 16
and a pendulum ball 18 fixed to the lower part of the swinging rod 16.
It consists of and. The watch body 10 has a fixed support 2
The knife edge 10a of the watch body 10 is supported in a V-groove 20a of the fixed support 20.

In order to swing the watch body 10, a small pendulum 22 is housed inside the watch body 10 so as to be swingable. The pendulum arm 24 and the small pendulum 2
4 and small pendulum weights 26 and 28 fixed to both ends of the pendulum. When the pendulum 22 swings in the direction of the arrow A1, the change in the center of gravity of the watch body 10 causes the watch body 10 to swing in the direction of the arrow B1. The state will be as shown. On the other hand, when the pendulum 22 swings in the direction of the arrow A2, the change in the center of gravity of the watch body 10 causes the watch body 10 to swing in the direction of the arrow B2.
The watch body 10 is in the state shown by the two-dot chain line C2.

Therefore, it is understood that the rocking motion of the small pendulum 22 changes the center of gravity position of the timepiece body 10 and allows the rocking motion of the timepiece body 10 to be maintained.

Next, FIG. 2 shows a clock body 10 of a full-body swing clock according to an embodiment of the present invention, and FIG. 3 shows a cross section thereof, showing a clock drive mechanism for displaying a predetermined time and a clock drive mechanism for driving a small pendulum. The small pendulum drive mechanism is provided within the watch body 10.

First, the timepiece drive mechanism will be explained.

A rotor 32 as a driving source is provided on the clock base plate 30, and the rotation of the rotor 32 is controlled by the fifth wheel 34, 4.
The deceleration is transmitted to the minute wheel 40 via the number wheel 36 and the third wheel 38, whereby the minute hand 42 and hour hand 44 rotate to display a predetermined time. The clock-driven wheel train includes a fifth wheel 34, a fourth wheel 36,
It includes a third wheel 38 and a minute wheel 40. That is, the fifth wheel 3 is attached to the rotor pinion 46 fixed to the rotor 32.
4 meshes with the fifth wheel 34, and the fifth wheel 34 is fixed coaxially with the fifth wheel 34.
The number 4 wheel 36 meshes with the number pinion 48, and furthermore, the number 4
The number 4 pinion 50, which is fixed coaxially with the number wheel 36, has a 3
The number wheel 38 is engaged, and the minute wheel 40 is engaged with a third pinion 52 provided coaxially with the third wheel 38.
Further, a minute hand wheel 56 is engaged with a minute hand pinion 54 that is integrally formed coaxially with the minute wheel 40, and an hour hand wheel 60 is engaged with a date pinion 58 that is fixed coaxially with the minute wheel 56. . The rotation of the rotor 32 is then decelerated and transmitted to the minute wheel 40, and the rotation of the minute wheel 40 causes the minute hand 42 to rotate.
The rotation at 0 is decelerated by the minute wheel 56 and the hour hand wheel 60.
This causes the hour hand 44 to rotate.

Therefore, in the watch drive mechanism, the rotor 32
The rotation is decelerated and transmitted through the fifth wheel 34, fourth wheel 36, and third wheel 38 to rotate the minute hand 40 and hour wheel 60. Therefore, the minute hand 42, which is fixed coaxially with the minute hand 40, is rotated. Further, the hour hand 44 fixed coaxially with the hour hand wheel 60 can be rotated, and a predetermined time can be displayed.

Next, the wheel train of the small pendulum drive mechanism will be explained.

The small pendulum drive wheel train includes an escape wheel 62 having teeth around the periphery, and an ankle body 64 that engages with the escape wheel 62 to swing and is connected to the small pendulum 22,
The ankle body 64 has two ankle pins 64.
a and 64b are extended and fixed so as to be engageable with the escape wheel 62. The swing of the small pendulum 22 causes the ankle body 64 to swing, thereby causing the escape wheel 6 to swing.
2 will be fed one tooth at a time.

In order to apply a predetermined rotational force to the escape wheel 62, a transmission wheel 68 meshes with an escape pinion 66 fixed coaxially with the escape wheel 62. A transmission wheel 70 is provided coaxially with the transmission wheel 68, and both transmission wheels are connected to each other. car 68,70
For example, a spring 72 is inserted between them as a biasing means. That is, the spring 72 is
One end of the spring 72 is locked to a pin 68a fixed to a transmission wheel 68, and the other end is locked to a pin 70a fixed to a transmission wheel 70. As the transmission wheel 70 rotates, a spring 72 is wound up and stored energy. The biasing torque of the spring 72 is transmitted to the escape wheel 62 via the transmission wheel 68 and the escape pinion 66 to increase the speed of the escape wheel 62, thereby imparting a predetermined rotational force to the escape wheel 62.

Therefore, the engagement state between the escape wheel 62 and the pallet wheel 64 changes due to the swing of the small pendulum 22 (pallet body 64), and a predetermined rotational force is applied to the escape wheel 62 by the spring 72. Because there are
The swinging movement of the ankle body 64, that is, the small pendulum 22 can be featured.

As described above, in the small pendulum drive mechanism, the state of engagement between the escape wheel 62 and the pallet body 64 changes, and the pallet body 64 swings, so that the small pendulum 22 connected to the pallet body 64 swings. This allows the watch body 10 to maintain its rocking motion, as shown in FIG.

In the embodiment, the clock drive wheel train and the small pendulum drive wheel train are disposed in conjunction with each other, and the clock drive wheel train winds up the biasing means to store energy, and the two wheel trains are combined into a single drive source. It is moving backwards. That is, a clock drive wheel train including a fifth wheel 34, a fourth wheel 36, a third wheel 38, a minute wheel 40, an escape wheel 62,
A time adjustment wheel 74 that meshes with both wheel trains is provided between the ankle body 64 and the small pendulum drive wheel train including the transmission wheels 68 and 70, and the time adjustment wheel 74 allows the two wheel trains to be interlocked. Time adjustment car 74
An intermediate pinion 76 that meshes with the minute hand wheel 40, an intermediate wheel 78 provided coaxially with the intermediate pinion 76, and a time adjustment knob 80 provided on the opposite side of the intermediate pinion 76 with respect to the clock base plate 30. including intermediate wheels 7
8 meshes with a transmission pinion 82 fixed coaxially with the transmission wheel 70. Therefore, the time adjustment wheel 74
The clock drive wheel train and the small pendulum drive wheel train are arranged in conjunction with each other, and the clock drive wheel train can wind up and store the spring 72, and both wheel trains are driven by a single drive source. It becomes possible to do so.
That is, the rotation of the rotor 32 is caused by the rotation of the fifth wheel 34, 4.
The deceleration is transmitted to the minute wheel 40 via the number wheel 36 and the third wheel 38, whereby a predetermined time is displayed.
As a result, the rotation of the minute wheel 40 is transmitted to the small pendulum drive wheel train at an increased speed, and the spring 72 is wound up and stored, so that the above-described swinging of the small pendulum 22 (ankle body 64) is maintained.

As described above, in the configuration of the embodiment, the clock drive wheel train and the small pendulum drive wheel train are arranged in conjunction with each other by the time adjustment wheel 74, and the spring 72 is wound up and stored by the clock drive wheel train. , and both wheel trains can be driven by a single rotor 32. Therefore, since both wheel trains are arranged in conjunction with each other, the watch body 10 can be made thinner and smaller.

In the embodiment, one axis of the clock drive wheel train and the small pendulum drive wheel train is cantilevered by the clock base plate 30, and the open side thereof is supported by the auxiliary base plate 84.
Since the watch body 10 has a structure covered with , it is possible to further reduce the thickness and size of the watch body 10. Further, since the auxiliary base plate 84 is made of a transparent plate constituting a clock face, and the two wheel trains are made of metal, the two wheel trains can be visually observed from the outside on the side of the auxiliary base plate 84 (transparent plate). Therefore, it can give a sense of novelty to the viewer and have a great aesthetic effect.
(See Figure 2). Furthermore, in the embodiment, since the watch body 10 is thin and small, a dry battery 85 for driving the rotor 32 is used as shown in FIG.
(AA size in the embodiment) can be stored in parallel with the clock base plate 30 and the auxiliary base plate 84.
The watch body 10 can be made even thinner and smaller.

In addition, in the embodiment, since the clock drive wheel train and the small pendulum drive wheel train are arranged in conjunction with each other, when the timepiece is started, the clock drive wheel train causes the spring 7 to
2 is automatically wound up and stored. Therefore, due to the winding energy storage, energy for self-starting is stored in the spring 72, and the watch body 10 is activated at the time of starting.
can be self-starting.

Furthermore, in the embodiment, the hands of the clock can be set by rotating the time adjustment wheel 74 in the forward direction.
Moreover, the initial biasing force can be wound up and stored in the spring 72 of the small pendulum drive wheel train. That is, since the intermediate pinion 76 of the time adjustment wheel meshes with the minute wheel 40, and the intermediate wheel 78 of the time adjustment wheel 74 meshes with the transmission pinion 82 of the transmission wheel 70, the time adjustment knob 80 cannot be manually operated. By rotating in the forward direction, the minute hand wheel 40 can be rotated to set the hands of the clock, and the rotation of the intermediate wheel 78 can wind up the spring 72 to store energy.
can give an initial biasing force to. Therefore, since the rotation of the time adjustment wheel 74 can apply an initial biasing force to the spring 72, there is an advantage that the rocking startability of the timepiece body is good.

Furthermore, in the embodiment, the time adjustment wheel 74 is provided with a slip mechanism, and this slip mechanism is shown in FIG.

In FIG. 4, the intermediate pinion 76 is fixed to the axle 86 of the time adjustment wheel 74 by press fitting, and the axle 86 is fixed to the axle 86 of the time adjustment wheel 74.
An intermediate wheel 78 is loosely fitted between the axle 86 and the intermediate pinion 76, and a spring 88 is inserted between the axle 86 and the intermediate wheel 78. The intermediate wheel 78 is elastically connected to the pinion 76 and is configured to slip with respect to the intermediate pinion 76 when a torque greater than a predetermined torque is applied. Therefore, when the time adjustment wheel 74 is rotated to set the hands of the clock, the minute hand wheel 40 rotates and the transmission wheel 70 also rotates, and the biasing force is wound up and stored in the spring 72. When a torque greater than a predetermined torque is applied to the spring 72, the intermediate wheel 78 slips against the intermediate pinion 76 due to the slip mechanism, so that a torque greater than the predetermined torque is prevented from being applied to the spring 72. This makes it possible to prevent the spring 72 from being destroyed or damaged.

The slip mechanism described above is applied not only to the time adjustment wheel 74 but also to the third wheel 38. That is, the third wheel 38 is moved to the third pinion 5 by the spring 90.
Therefore, when the time adjustment wheel 74 is rotated to adjust the time, the load of the minute wheel 40 at the time of adjustment is prevented from being transmitted to the rotor 32. It becomes possible to do so.

A preferred embodiment of the present invention has the above configuration,
The effect will be explained below.

First, when the timepiece is started, the time adjustment wheel 74 is manually operated to rotate the minute hand wheel 40 and the hour hand wheel 60, thereby adjusting the hands of the timepiece. Furthermore, the rotation of the time adjustment wheel 74 winds up and stores the initial biasing force in the spring 72, thereby providing more sufficient rocking startability, for example, by adjusting the hands for about 15 minutes. At this time, as described above, since the time adjustment wheel 74 is provided with a slip mechanism, a torque exceeding a predetermined torque is not applied to the spring 72.

In this way, preparations for starting the timepiece are completed, and then the rotor 32 is rotated by the current from the power source. The rotation of the rotor 32 is caused by the fifth wheel & pinion 34,
The deceleration is transmitted to the minute wheel 40 via the fourth wheel 36 and the third wheel 38, and the minute wheel 40 and hour wheel 60 rotate, so the minute hand 42 and hour hand 44 rotate, thereby displaying a predetermined time. will be exposed. Furthermore, the rotation of the minute hand wheel 40 is transmitted to the transmission wheel 70 via the time adjustment wheel 74 at an increased speed, and the spring 72 is wound up and stored, so that the rotation of the minute hand wheel 40 is increased.
A predetermined rotational force can be applied to the escape wheel 62. Below, based on Figures 1, 5, and 6, the small pendulum 22
The rocking motion of the ankle body 64 will be explained.

In FIGS. 5 and 6, the ankle body 64 is swingably supported by the small pendulum fulcrum 24a, and the escape wheel 62 is moved by the arrow D due to the biasing force of the spring 72.
biased in the direction. And ankle body 64
The ankle pins 64a, 64b are engaged with the escape wheel 62.

First, when the watch body 10 is in the state shown by the two-dot chain line C2 in FIG. 1, the small pendulum 22 swings so as to maintain a state of balance due to gravity. That is, as shown in FIG. 5, the ankle pins 64a, 6 of the ankle body 64 connected to the small pendulum 22
4b and the escape wheel 62 change, the pallet pin 64a meshes with the escape wheel 62, the pallet pin 64b separates from the escape wheel 62, and the escape wheel 6
2 is fed by one tooth. At this time, since a rotational force in the direction of arrow D is applied to the escape wheel 62, a swing biasing force is applied to the pallet body 64, and the small pendulum 22
The rocking motion in the direction of arrow A2 is increased, and the watch body 10 is urged to rock.

Next, the watch body 10 returns to the position indicated by the two-dot chain line C1 in FIG.
When the state shown in is reached, the small pendulum 22 swings so as to maintain a state of balance due to gravity. That is, as shown in FIG.
4 and the escape wheel 62 changes, the pallet pin 64a moves away from the escape wheel 62, and the pallet pin 64b meshes with the escape wheel 62.
is sent one tooth. At this time, since a rotational force in the direction of arrow D is applied to the escape wheel 62, a rocking biasing force is applied to the ankle body 64, and the watch body 10 is rockingly biased by the same action as described above. The Rukoto.

Therefore, in the small pendulum drive mechanism of the embodiment,
Since the spring 72 applies rotational force to the escape wheel 62 in the direction of arrow D, the escape wheel 62
can apply a swing biasing force to the ankle body 64, thereby making it possible to replenish pendulum energy lost due to friction or the like. Therefore, since the small pendulum 22 can always perform the rocking motion normally, the rocking motion of the watch body 10 can be sustained.

As described above, according to the embodiment, since the clock drive wheel train and the small pendulum drive wheel train are arranged in conjunction with each other, the biasing means of the small pendulum drive mechanism can be wound and stored by the clock drive wheel train. Both wheel trains can be driven by a single drive source. Therefore, the watch body can be made thinner and smaller. Furthermore, since one of the axes of the two wheel trains is cantilever-supported by the watch base plate, and the free side thereof is covered by the auxiliary base plate, it is possible to further reduce the thickness and size of the watch body. becomes. Furthermore, the auxiliary base plate 84 is made of a transparent plate that constitutes the dial of the clock, and both wheel trains can be viewed from the outside on the auxiliary base plate (transparent plate) side, giving the viewer a sense of novelty. , which has great aesthetic effects.

In addition, in the embodiment, a time adjustment wheel that meshes with both wheel trains is provided between the clock drive wheel train and the small pendulum drive wheel train, so that the hands of the clock are set by rotation of the time adjustment wheel. can be done, and
The initial biasing force can be wound up and stored in the biasing means of the small pendulum drive mechanism, and the timepiece can be started smoothly. Furthermore, since the time adjustment wheel is provided with a slip mechanism, when the time adjustment wheel rotates, the slip mechanism applies a biasing force greater than a predetermined biasing force to the biasing means of the small pendulum drive mechanism. It is possible to prevent this from happening. Therefore, the slip mechanism can prevent the urging means from being destroyed or damaged, and it is possible to always apply a predetermined urging force to the urging means.

In the embodiment, the transmission wheel 70 is set to rotate at a higher speed than the minute wheel 40. Further, the spring 72 is wound up and stored at a rate of one revolution every 20 seconds. Also, escape wheel 62
The escape wheel 62 is fed by one tooth and rotates at a rate of one revolution every 40 seconds.
4b and swings the ankle body 64 at a cycle of 2 seconds. Further, the spring 72 is set so that its winding speed is faster than its unwinding speed.

Furthermore, conventionally, in order to set the hands of a clock, a special gear was meshed with the minute wheel, and the hands of the clock were set by rotating the gear.
In the embodiment, the rotation of the minute wheel 40 is transferred to the transmission wheel 7.
Since the time adjustment wheel 74 is provided to increase the speed to 0, the hands of the clock can be set by rotating the time adjustment wheel 74. is no longer necessary, making the structure simpler.
