On the other hand, the movement (2) is only rotating the hour hand 23 and the minute hand 24 and the cam plate 26 and the differential cam plate 28 for the other species at a predetermined time ratio, but does not transmit power for the other species. Do not.

Therefore, the present invention is characterized in that it adopts a DC motor that is a power unit separate from the movement, and this DC motor is driven by a reduction gear group composed of a plurality of gears for deceleration described below. Will be delivered.

The DC motor (3) is attached to the fastening rod of the upper one side of the several fastening rods 13 for fastening the front and rear assembly plate (11, 12) by the support (31), and also the The small drive gear 32 is installed in the output shaft of the DC motor 3, and is configured to operate a power transmission device for other types by the rotational force of the small drive gear 32.

That is, the primary large interlocking gear 33 is meshed with the small drive gear 32, and the secondary large interlocking gear 35 is disposed with the primary small interlocking gear 34 coaxially installed with the primary large interlocking gear 32. ) Is meshed with another type of gear 41 in the secondary small interlocking gear 36 coaxial with the secondary large interlocking gear.

The rotary gear 42 is installed at the upper end of the shaft 4 on which the other gear 41 is installed. The rotary gear is attached to the upper side of the shaft 37 of the secondary large and small interlocking gears 35 and 36. It is engaged with the small driven gear 38.

Even if the second small interlocking gear 36 and the small driven gear 38 installed on one shaft 37 are simultaneously engaged with the other gear 42 and the rotary gear 42 provided on the other shaft 4, The two shafts 37 and 4 are designed to rotate accurately at a fixed rotation ratio.

The other gear 41 has a plurality of protrusions 43 for activating the operation of the other type of hammer (not shown) is projected at equal intervals, and the rotary gear 42 has a latch arm 6 stepwise The eccentric rod 44 for raising upwards protrudes.

The latch arm 6 is elastically installed so that a force to rotate (or drop) downward is always applied by a spring (not shown) in the hinge 61 rotatably coupled to the front assembly plate 11. The arm 6 has a number of teeth 63 formed in the arc part 62 to perform 12 different types, and a support arm 64 supported on the cam surface by time of the differential cam plate 28 is integrally formed. Is attached.

The stopper arm 7 for controlling the latch arm 6 is hinged 71 at the upper end side of the front assembly plate 11, but is elastically installed by a spring to always move to the latch arm side.

Therefore, in the state in which the other type operation is stopped, the engaging end 72 of the stopper arm 7 supports the end of the arc portion 61 of the latch arm 6, and the stopper arm 7 is electrically connected to the stopper arm 7. A movable contact rod 73 for contact operation is attached.

The operation arm 74 formed integrally with the stopper arm 7 is configured to move by the other type setting operation 8 to operate the stopper arm 7.

That is, the other type setting operation period 8 is attached to the rotation hinge point 81, and one side end 82 thereof is attached to the cam part 26a of the cam plate 26 and the cam part 26b for 30 minutes. The other end portion 83 is configured to operate the operating arm 74 while moving together as the one end portion 82 is rotated.

In addition, an insulating rod 84 is protruded from the other end portion 83 side of the other type setting operation 8, and the insulating rod 84 is elastically installed on the insulator 9 fixedly attached to the front assembly plate 11. The leaf spring 91 is configured to control the elastic restoring force at all times.

And the circuit configuration of the battery (B) and the on / off switch (SW) for supplying power to the DC motor (3) is as follows.

The (-) pole of the battery B and the (-) pole terminal of the DC motor 3 are connected in series with a wire, and the wire drawn out from the (+) pole terminal of the DC motor 3 is a stopper arm 7 ).

The wire connected to the positive electrode of the battery B is connected to the leaf spring 91 while the on / off switch SW is connected in series.

In the above, the leaf spring 91 to which the wire of the positive electrode of the battery B is connected is kept short with all the components as well as the front assembly plate 11 by the insulator 9. However, the power of the battery B can be supplied to the DC motor 3 only when the movable contact rod 73 comes into contact with the leaf spring 91 by the operation of the stopper arm 7 when the other type of operation is performed. It is made up.

Referring to the operation of the present invention configured as described above are as follows.

First of all, the other operation of the present invention is configured to be possible only when the power of the battery B is supplied to the DC motor 3, so that the on / off switch SW installed in an exposed state on one side of the wall clock case is turned off. When operated in the grandfather clock is the hour hand 23 and the minute hand 24 by the movement (2), but the devices (parts) for the other species will not be able to produce the bell sound. Therefore, in the case of the night so that the user does not sound the bell sound for a good night's sleep when the on / off switch (SW) off before bedtime clock will not be a bell clock so that the user can sleep comfortably.

When the next clock is to perform the other type of operation, when the on / off switch (SW) is operated in the on state, the power of the battery (B) is supplied to the DC motor (3) and the other type of operation is 30 minutes. And the other type of operation is carried out in units of time, an embodiment thereof will be described as shown in the example of Figure 3 and 4 as follows.

As shown in the example of FIG. 3, the stopper arm (a) in the state where the cam part 26 of the cam plate 26 or the cam part 26b for 30 minutes does not push out the one end 82 of the other type setting operation 8. 7 is a state in which the locking end 72 of the latch arm 6 supports the end of the arc portion 62, and the movable contact bar 73 of the stopper arm 7 is spaced apart from the leaf spring 84. In this state, the battery B and the DC motor 3 are open circuited and the DC motor 3 is not driven even when the on / off switch SW is operated in the on state. to be.

When the minute hand 24 reaches a position indicating 30 minutes or an hour as time passes in the above state, the cam part 26b for the 30 minute seeding of the cam plate 26 installed on the minute hand shaft 22 or the time seeding type As the cam part 26a pushes out one end 82 of the other type setting operation 8, other type operation is performed. As shown in the example of FIG. 4, the cam type 26a for time type operation is performed between the type setting operation 8. For example, pushing the one side end 82 of the), and when the other time is six o'clock described as an example, when the time type cam portion 26a pushes the one end 82, the other type setting operation ( 8) itself rotates counterclockwise from the rotation hinge point 81, and thus the other end portion 83 also rotates counterclockwise while operating arm 74 integral with the stopper arm 7. While pushing the rod, the insulating rod 84 of the type setting operation 8 pushes the leaf spring 91 elastically. That is the condition.

As described above, when the stopper arm 7 rotates clockwise from the hinge 71, the locking end 72 is completely out of the arc portion 62 of the latch arm 6, and the latch The arm 6 is lowered by the elastic restoring force of the spring, and the free end of the support arm 64 integrally attached to the latch arm 6 is 6 of the differential cam plate 28 installed on the hour hand shaft 21. The arc portion 62 of the latch arm 6 falling downward while being supported by the trial cam surface falls only to the position where the sixth type can ring.

On the other hand, in the state in which the time-driven cam portion 26a does not completely deviate from one side end 82 of the type-setting operation 8, the insulating rod 84 moves the leaf spring 91 to the opposite side (left side in the drawing). Even if the stopper arm 7 moves clockwise (left side in the drawing) by the operation of the other end 83, the movable contact bar 73 is spaced apart from the leaf spring 91. After that, when the time type cam portion 26a is completely out of the one end 82, the other type setting operation period 8 is returned to its original position by the elastic restoring force of the spring (not shown), and thus the stopper arm ( 7) and the leaf spring 9 are also returned to their original state. At this time, the engaging end 72 of the stopper arm 7 is connected to the arc 63 of the arc 62 of the latch arm 6 which has been previously operated. The spring spring 91 is unable to return to its original state. In this case, the leaf spring 91 is elastically connected to the movable contact rod 73. When the leaf spring is connected to the movable contact rod, the battery B and the DC motor 3 have a closed circuit state. Therefore, the DC motor 3 is driven, and the driving force is the small drive motor 32 → the primary large interlocking gear 33 → the primary small interlocking gear 34 → the second large interlocking gear 35 → 2. The small interlocking gear 36 and the small follower gear 38 → the second gear 41 and the rotary gear 42 are transferred to the second gear 41 to operate the second hammer 5. The eccentric rod 44 of 42 is to move the teeth 63 of the latch arm 6 per revolution step by step, and the latch arm 6 completes the step-up by a predetermined number of types. When the stopper arm 7 is in a state of being completely out of the end of the teeth 63 and the arced portion 62 of the stopper 72 of the stopper arm 7 Due to the elastic restoring force of the spring, it rotates in the counterclockwise direction (right side in the drawing), in which case the movable contact bar 73 is spaced apart from the leaf spring 91, whereby the battery B and the DC motor 3 are moved. Is in the open circuit state and the DC motor 3 is stopped and simultaneous type operation is also stopped.

And once the operation in the other 30 minutes, the movement distance that the cam part 26b for 30 minutes of the cam plate 26 pushes one end portion 82 of the other type setting operation 8 is the other end portion 83 on the opposite side thereof. ) Is configured such that the engaging end 72 of the stopper arm 7 moves only as far as the end of the arc portion 62 of the latch arm 6, but the teeth 63 do not escape, and the stopper arm 7 Movable contact bar 73 of the) will be in the state connected to the leaf spring 91, the other type at this time is to proceed once and then stop.

On the other hand, in the above, the ruled clock using the movement as an embodiment, the present invention applied to the DC motor, the battery and the on / off switch is also applicable to the clocked clock using the mainspring or weight.

According to the present invention as described above as a configuration for installing a DC motor, a battery and an on / off switch and other power transmission structure that is a separate power source from the power unit for clock operation in the timepiece assembly of the clock. The user can select the other type of device to make the type of seeding at the same time as the existing clock, so that the type can be done by the hourly unit and the 30 minute unit. In the case of the nighttime, the type can be eliminated by the sound of the other type. It is a practical design that can stop the device and bring you a good night's sleep.
