Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a movement device for decorating a timepiece.

[0002]

[Prior art]

 In recent years, many indoor clocks such as table clocks and wall clocks are of the electric type that do not require a pendulum. In this electric timepiece, a clock signal is generated, a motor is rotated in synchronization with this clock signal, and the hand of the timepiece is made to step by this motor.

[0003]

[Problems to be solved by the device]

 By the way, in the electric timepiece described above, the pendulum is not necessary because the hands are stepped by the motor as described above, but the pendulum is sometimes provided only for decoration. This is because electric timepieces have almost the same performance, and in order to increase their commercial value among the various timepieces on the market, they have to rely on decoration. In other words, the decoration of watches has become diversified, and watches with more individuality and higher commercial value have been desired.

Therefore, an object of the present invention is to provide a movement device for a timepiece capable of achieving a unique decoration.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the present invention, a display board which is swingably supported by a fulcrum spaced from the timepiece shaft and has a hole through which the timepiece shaft penetrates, and a drive means for swinging the display board. And a small plate attached to the timepiece shaft and covering the hole of the display plate.

[0006]

[Action]

 According to the invention of the above-mentioned structure, the display board is supported by the fulcrum spaced from the timepiece shaft, and is swung by the driving means. A clock shaft passes through the hole of the display board, and therefore, the swing range of the display board is limited by the contact of the clock shaft with the edge of the hole of the display board. In addition, since the small plate that covers the hole of the display board is attached to the clock shaft, the hole of the display board is hidden by the small board and cannot be seen from the front.

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is an exploded assembly view of a timepiece to which an embodiment of the movement device according to the present invention is applied, and FIG. 2 is a sectional view of the timepiece. As shown in these figures, a timepiece shaft 2 projects from the timepiece unit 1, and the timepiece shaft 2 penetrates a hole 3 a of the support plate 3. When the base 4 is screwed into the timepiece shaft 2, the support plate 3 is sandwiched between the base 4 and the timepiece unit 1, whereby the timepiece unit 1 is fixed to the support plate 3.

Next, the timepiece shaft 2 is passed through the hole 5a of the display board 5, and then the minute hand 6 for engraving an hour and the long hand 7 for energizing a minute are attached to the timepiece shaft 2. Further, a small plate 8 for marking seconds is attached to the clock shaft 2.

On the other hand, a swing column 9 is swingably supported on the back side of the timepiece unit 1. A swing frame 10 is connected to the swing column 9, and the swing frame 10 swings together with the swing column 9. Further, the swing frame 10 is provided with four arms 11, and these arms 11 are adhered to the back side of the display board 5 to support the display board 5. Therefore, the swing column 9, the swing frame 10, and the display board 5 swing together.

Further, the support plate 3 has two small holes 3b formed therein. When two screws (not shown) are screwed into the screw holes 13 of the back lid 12 through the small holes 3b, respectively. The support plate 3 is fixed to the back cover 12, and along with this, the timepiece unit 1, the display panel 5, the swing frame 10, etc. are disposed inside the back cover 12. After that, the glass plate 14 is fitted into the window 15a of the outer case 15, the outer case 15 and the back cover 12 are overlapped, and both are fastened with the respective screws 16, whereby the timepiece is completed.

FIG. 3 shows the front of the timepiece. As is apparent from this figure, the diameter of the display board 5 is larger than the diameter of the window 15a of the outer case 15, and therefore the peripheral edge 5b of the display board 5 is hidden behind the outer case 15 and cannot be seen. Further, the small plate 8 attached to the timepiece shaft 2 is sufficiently larger than the hole 5a of the display board 5 and hides this hole 5a, so that this hole 5a cannot be seen from the front.

FIG. 4 shows the timepiece unit 1, the swing frame 10, the support plate 3, and the display panel 5 as viewed from the back side. As shown here, a battery 17 is attached to the timepiece unit 1, and the timepiece unit 1 operates by using the battery 17 as a power source to rotate the minute hand 6, the minute hand 7 and the platen 8. The swing column 9 of the timepiece unit 1 is supported by the fulcrum A 1 and can swing right and left. A socket 9a is formed on the upper side of the rocking column 9, and a convex portion 10a of the rocking frame 10 is inserted into the socket 9a and is sandwiched therein. As a result, the swing column 9 and the swing frame 10 are connected, and the swing frame 10 and the display board 5 supported by the swing frame 10 swing as the swing column 9 swings.

A permanent magnet 18 is fixed to the lower side of the swing column 9, and an electromagnet (not shown) is built in a portion of the timepiece unit 1 facing the permanent magnet 18. Both poles of this electromagnet are periodically inverted, whereby the permanent magnet 18 is pushed and pulled, and the swing column 9 swings. The display board 5 also swings with the swing of the swing column 9.

In the timepiece having such a structure, as shown in FIG. 3, the peripheral edge 5b of the display board 5 is hidden behind the outer case 15 and cannot be seen, and the hole 5a of the display board 5 has the small board 8a. When the display board 5 supported by the fulcrum A is shaken as shown by an arrow B, the pattern drawn on the display board 5 is rocked. Further, the platen 8 rotates every second.

In the timepiece of the above embodiment, disks are illustrated as the display board 5 and the small board 8, but these display boards and small boards may have any shape. Further, the small board 8 is attached to the timepiece shaft 2 in place of the second hand, but may be attached in place of the long hand and the short hand. Further, instead of the second hand, the long hand, and the short hand, three discs of different sizes may be attached so as to be stacked.

[0017]

【effect】

 As described above, according to this invention, the display board swings, and the small board which hides the hole of the display board rotates instead of the hands of the clock. Therefore, it is possible to make a unique decoration of the timepiece by using these display boards and small boards.
