Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a timepiece clock that emits different bell sounds at half hour.

[0002]

[Prior art]

 Other than the alarm sound, there are two types of time alerts, one that sounds only on the hour and one that alerts on the hour and half hour. The time signal sounds include an electronic sound using an electronic circuit such as a melody IC and a bell sound obtained by striking a metal sounding body such as a bell or a bell (hereinafter simply referred to as "sounding body").

[0003]

[Problems to be solved by the device]

 The bell sound has a clear tone and is extremely comfortable to listen to. However, there is a problem that the striking mechanism becomes complicated when trying to report with different sounds for the hour and the half hour.

Therefore, it is conceivable to obtain different sounds or tones by controlling the driving of the striking motor without changing the existing striking mechanism. However, in this case, means for automatically controlling the driving of the striking motor must be devised. The present invention has been made from the above viewpoint.

[0005]

[Means for Solving the Problems]

 That is, the timepiece timepiece of the present invention has a striking mechanism that generates different striking sounds by rotating the striking motor forward and backward, and drives the striking mechanism every 30 minutes on the hour and half an hour. A drive contact mechanism that generates a motor drive start signal to start, a time code plate that has a time code corresponding to the time of the hands and a specific code that is different from each time code between all time codes, When the time code is detected from the time code plate based on the motor drive start signal, either one of the forward rotation signal and the reverse rotation signal of the striking motor is output, and the other when the specific code is detected. Drive circuit for outputting the driving signal to the striking motor by inputting the forward / reverse rotation discrimination circuit that outputs the signal of the driving contact mechanism, the motor drive start signal of the drive contact mechanism, and the output signal of the forward / reverse rotation discrimination circuit. With circuit .

[0006]

[Action]

 Normally, the striking motor is stopped. The time code is detected when the positional relationship between the time code plate and the sliding contact plate is immediately before any one of the hours from 1 o'clock to 12 o'clock, and when this detection signal is input to the forward / reverse rotation discriminating circuit, the normal time is detected.・ The reverse rotation discrimination circuit outputs a normal rotation signal for the driving motor for the striking mechanism to the striking mechanism control circuit. When the hour comes thereafter, a motor drive start signal is output from the drive contact mechanism to the striking mechanism control circuit. As a result, the striking motor is rotated in the normal direction, and the bell sound for the hour is generated.

Further, when the positional relationship between the time code plate and the sliding contact plate reaches a specific code detection position, a forward / reverse rotation discriminating circuit outputs a reverse driving signal for a striking motor to the striking mechanism control circuit. At half hour thereafter, a motor drive start signal is output to the striking mechanism control circuit, and the striking motor reversely rotates to generate a half-hour beating sound.

As shown in FIG. 5, the rotary plate 40 has a through hole 42 at the center for penetrating the striking cam shaft 37, and projections 44 and 46 on both side surfaces, respectively. 46 is a position required from the center of the rotating plate 40 as a position to be inserted into the long holes 57 and 67 of the striking cams 50 and 60 when the rotating plate 40 and the striking cams 50 and 60 are attached to the striking cam shaft 37. It is formed at a position with a distance. Further, the first protrusion 44 provided on one side of the rotary plate 40 and the second protrusion 46 provided on the other side of the rotary plate 40 form an angle of about 90 degrees at the center of the rotary plate 40. It is arranged so that there is a residual angle difference.

Further, in this embodiment, two rod bells 10 are used as a sounding body, and as a batting rod for hitting the rod bell 10 has a ball for hitting the bell 10 at its tip. Two striking rods are provided, which swing around the support shaft 19 and tap the rod 10 with the above-mentioned striking balls.

The cam levers 15 and 25 are arranged close to each other, and by the rotation of the striking cams 50 and 60, the cam levers 15 and 25 are pushed by the striking cams 50 and 60, respectively. When the batting balls 13 and 23 are pulled away from the vicinity of the bell 10 when they are separated from each other, and when the batting cams 50 and 60 rotate to pass the positions of the cam levers 15 and 25, the cam levers 15 and 25 are re-launched. The ball 37 approaches vigorously, and at this time, the ball 10 is hit with each of the hit balls 13, 23.

It is arranged that the bells and the like are not beaten faster than the second hit bell 21 having the support plate 27, so that the second hit bell 21 having the support plate 27 hits the bell 10 first, or Alternatively, the first bells 11 are regulated so that the two bells 11 and 21 hit the bell 10 at the same time.

Since this embodiment is formed as described above, when the rotary plate 40 is rotated clockwise, for example, the protrusions 44 and 46 provided on the rotary plate 40 are provided on both sides of the rotary plate 40. The striking cams 50 and 60 also rotate, and as shown in FIG. 6A, the cam lever 15 of the first striking rod 11 having no support plate 27 and one end 55 of the main body portion 54 of one striking cam 50 come into contact with each other. When one protrusion 44 of the rotary plate 40 comes into contact with the end 58 of the long hole 57 of the striking cam 50 (hereinafter referred to as the first striking cam), the first protrusion 44 (hereinafter referred to as the first protrusion) rotates according to the rotation of the protrusion 44. The one hitting cam 50 moves the cam lever 15 of the first hitting bar 11 away from the hitting cam shaft 37 to separate the hitting ball 13 from the bell, and the second hitting bar 21 having the support plate 27. Strike the other to the cam lever 25 of With one end 65 of the main body 64 of the cam 60 (hereinafter referred to as the second striking cam) in contact with the end portion 88 of the long hole 67 provided in the second striking cam 60, the protrusion 46 provided on the other side surface of the rotary plate 40. 6B, the cam lever 25 of the second striking rod 21 is also moved away from the striking cam shaft 37 in accordance with the rotation of the rotary plate 40, and the second striking bell is contacted. The hit ball 23 of the rod 21 is also separated from the rod bell 10.

Then, as shown in FIG. 7A, after the body portion 54 of the first striking cam 50 reaches a position where it is disengaged from the cam lever 15 of the first striking rod 11, as shown in FIG. In the section until the body portion 64 of 60 reaches the position where it is disengaged from the cam lever 25 of the second striking rod 21, the striking cam lever 25 of the second striking rod 21 is separated from the striking cam shaft 37 by the second striking cam 60. The first striking rod 11 is held by the support plate 27 provided on the second striking rod 21, and the cam lever 15 of the first striking rod 11 is also held at a position away from the striking cam shaft 37. .

After that, when the end portion 66 of the main body portion 64 of the second striking cam 60 slightly passes the contact position with the cam lever 25, the second protrusion 46 is inserted into the elongated hole 67 of the second striking cam 60. Therefore, as shown in FIG. 7C, the cam lever 25 of the second striking rod 21 moves the second striking cam 60 so that the end 68 of the slot 67 of the second striking cam 60 is separated from the second protrusion 46. The main body 64 can be pushed forward to approach the hitting cam shaft 37, and the bell 10 can be hit by the hitting ball 23 of the second hitting bar 21.

At this time, since the first striking rod 11 is held by the support plate 27 of the second striking rod 21, the first striking rod 11 also operates simultaneously with the second striking rod 21, The ball 13 of the bell 11 is also hit at the same time as the ball 23 of the second bell 21.

When the rotating plate 40 is rotated in the reverse direction with the rotation direction of the drive motor 31 being reversed, as shown in FIG. 8A, the cam lever 25 of the second striking rod 21 is attached to the main body of the second striking cam 60. After the second projecting portion 46 is brought into contact with the end portion 69 of the elongated hole 67 in the second striking cam 60 while the one end 66 of the portion 64 is in contact with the second striking rod 60, the second striking rod is rotated according to the rotation of the rotating plate 40. The cam lever 25 of 21 is separated from the striking cam shaft 37, and the striking ball 23 of the second striking rod 21 is separated from the bell 10.

At this time, the ball 13 of the first bell 13 is also separated from the bell 10 by the support plate 27 provided on the second bell 21, and as shown in FIG. The cam lever 15 of No. 11 is also separated from the striking cam shaft 37 together with the cam lever 25 of the second striking rod 21, and the main body of the first striking cam 50 is provided between the cam lever 15 of the first striking rod 11 and the striking cam shaft 37. The part 54 will enter into rotation.

Then, as shown in FIG. 9A, the end portion 66 of the main body portion 64 of the second striking cam 60 reaches the contact position with the cam lever 25 of the second striking rod 21, and the position is reached. When the main body 64 of No. 0 passes, as shown in FIG. 9B, the cam lever 25 of the second striking rod 21 having the support plate 27 advances the rotation of the second striking cam 60 and the striking of the second striking rod 21. The ball 23 will strike the bell 10.

At this time, the first striking rod 11 is held with the cam lever 15 thereof separated from the striking cam shaft 37 by the main body portion 54 of the first striking cam 50, and as shown in FIG. While the rotary plate 40 rotates until the end 55 of the main body 54 of the cam 50 reaches the contact position with the cam lever 15, the striking ball 13 of the first striking rod 11 is at a position separated from the bell 10. It is held, and thereafter, as shown in FIG. 9D, the cam lever 15 of the first batting bar 11 pushes the first batting cam 50 forward to tap the bar bell 10 with the ball 13.

In this embodiment, when the rotary plate 40 is rotated clockwise as described above, the ball 13 for the first batting bar 11 and the ball 23 for the second batting bar 21 are simultaneously struck. When the ball 10 is hit and the rotary plate 40 is rotated counterclockwise, the hit ball 13 of the first hit bar 11 and the hit ball 23 of the second hit stick 21 can be hit separately to the hit stick 10. The simultaneous driving and the multi-step driving can be selected only by determining the rotation direction of the drive motor 31.

As described above, the present invention is a timepiece clock having a striking mechanism 100 that generates two types of striking sounds. Hereafter, simultaneous striking on the hour and multistage striking on the half hour are performed. An example of performing (tinting) will be described.

FIG. 10 is an enlarged cross-sectional view of a main part, where 80 is a lower plate, 81 is a circuit board, 82 is a middle plate, 83 is an hour hand wheel, 84 is a minute hand wheel, and 85 is a second hand wheel.

Reference numeral 86 denotes a drive contact mechanism for generating a motor drive start signal S1 for driving the bell-swing motor 1, and a cam wheel 89 having a hour cam projection 87 and a half hour cam projection 88. The contact plate 90 is integrally attached to the minute hand wheel 84, and the contact plate 90 faces the cam wheel 89 at half hour and half hour.

The contact plate 90 is elastically deformed by engaging with the cam protrusions 87, 88, and elastically returns when the engagement with the protrusions 87, 88 is released at half hour or half hour, and is not shown. Contact with fixed contacts. As a result, the start signal S1 is generated. As shown in FIG. 1, the start signal S1 is normally set to H level and becomes L level because the drive contact mechanism 86 is closed at half hour or half hour. When the L-level start signal S1 is input to the striking mechanism control circuit 2, the striking motor 1 starts rotating.

Reference numeral 91 is a position detection wheel which is rotatably supported between the lower plate 80 and the circuit board 81 and which meshes with the hour hand wheel 83 and rotates in synchronization with the hour hand wheel 83. As shown in FIG. 11, the position detection wheel 91 is provided with a sliding contact plate 92 in which five sliding contacts 92a, 92b, 92c, 92d, 92e are arranged in a straight line so as to be integrally rotatable. .

On the other hand, the circuit board 81 is provided with the code plate 3 shown in FIG. The code plate 3 is composed of a circular conductive portion E and fan-shaped conductive portions A, B, C and D which are concentric with the conductive portion E and are provided on different radii.

The sliding contacts 92a to 92d slide and come in contact with and separate from the conductive parts A to D of the code plate 3, and the sliding contact 92e and the conductive part E are always in a conductive state. The conductive portion E is always set to the H level, and the sliding contacts 92a to 92d change the output signals a to d from the conductive portions A to D of the code plate 3 from the L level to the H level.

The conductive parts A to D are radially divided into 24, and the radial regions represent the hour, that is, the time regions T1 to T12 that represent the time on the hour digit and the half hour, as shown in FIG. The half-hour regions M1 to M12 are alternately arranged.

Therefore, when the sliding contacts 92a to 92d are located in the time regions T1 to T12 of the code plate 3, the conductive parts A to D correspond to the numerical values of 1 to 12 by the binary system as shown in Table 1. The output signals a to d are output. Further, when the sliding contacts 92a to 92d are located in the half-hour regions M1 to M12, the sliding contacts 92a to 92d do not engage with the conductive parts A to D, so that the conductive parts A to D are all H level signals a to. Output d.

The striking motor 1 is set to rotate normally when the output signal S3 from the forward / reverse rotation determination circuit 4 is at L level and reverse when it is at H level. Such a technique requires signal processing that specifies the rotation direction. This will be described with reference to FIG.

Output signals a to d from the code plate 3 are input to the forward / reverse rotation discrimination circuit 4 and the striking mechanism control circuit 2. The forward / reverse discriminating circuit 4 is composed of a NOR gate 5 and an exclusive OR gate 6, and the output signals a to d are inputted to the NOR gate 5. The output signal S2 of the NOR gate 5 and the start signal S1 of the drive contact mechanism 86 are input to the exclusive OR gate 6.

The striking mechanism control circuit 2 detects the discrimination signal S3 of the forward / reverse rotation discriminating circuit 4, the start signal S1, the output signals a to d from the code plate 3 and the number of times the striking mechanism 100 strikes. The number-of-bells signal S4 from the number-of-times detector 7 is input.

Next, the operation will be described. Immediately before the hour before 1 o'clock to 12 o'clock, the output signal a corresponding to 1 o'clock to 12 o'clock shown in Table 1 is displayed on the NOR gate 4 depending on the engagement state of the sliding contacts 92a to 92d and the conductive portions A to D. ~ D are input, and the output signal S 2 of the NOR gate 5 is all at the L level. After that, when the hour comes, the drive contact mechanism 86 is closed, so that the start signal S1 becomes L level and the determination signal S3 of the exclusive OR gate 6 becomes L level. As a result, the striking motor 1 is set to rotate clockwise, whereby the striking sounds of the striking mechanism 100 can be simultaneously struck.

When the sliding contacts 92a to 92d are in positions where they do not engage with the conductive parts A to D, the output signals a to d are all at the H level, which causes the output signal S2 to be at the L level. After that, when it is half an hour, the drive contact mechanism 86 is closed, and when the start signal S 1 becomes L level, the determination signal S 3 of the exclusive OR gate 6 becomes H level. As a result, the striking motor 1 is set to rotate in the counterclockwise direction, which allows the striking sound of the striking mechanism 100 to be multi-stepped (chin-chan striking).

The striking mechanism control circuit 2 uses the output signals a to d from the code plate 3 and the striking number signal S4 from the striking number detection unit 7 to 1 to 12 times on the hour and 1 on the half hour. It controls the sound of beating the bells once.

Further, when the sliding contacts 92a to 92d are located in the half-hour regions M1 to M12, the sliding contacts 92a to 92d do not engage with the conductive portions A to D, so that the conductive portions A to D are all at the H level signal a.
