Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary decoration mechanism which obtains a driving force for a rotary decoration from a timepiece mechanism, and a restriction lever mold used for manufacturing a restriction lever mounted on the rotary decoration mechanism.

[0002]

2. Description of the Related Art In general, a rotary decorative timepiece has a rotating shaft composed of a decorative member fixedly mounted on a vertically supported bearing shaft, and the bearing shaft is rotated periodically to rotate the rotating decorative shaft. This is a rotational movement that switches the direction in the reverse direction. In addition, the rotational movement of the rotary ornament, the rotation direction does not switch immediately, the rotation slowly slows down,
It is said to be a movement that starts to rotate slowly again in the opposite direction after stopping for a moment.

[0003] The rotary decoration mechanism for performing such a rotary motion is obtained by a method of obtaining a driving force by a combination of an electromagnet and an elastic return means, a mechanism provided with a drive mechanism separate from a timepiece mechanism, a timepiece mechanism. And the like that obtains a driving force from a motor are known.

[0004] That is, a rotary decoration mechanism that obtains a driving force from the clock mechanism extracts rotational power from the clock mechanism that performs a timekeeping function, converts the rotary motion into a rocking motion by a rocking lever or the like, and then The oscillating motion is converted into a rotational motion and transmitted to the bearing shaft to rotate the rotary ornament.

[0005]

However, in the timepiece provided with the above-described rotary decoration mechanism, the movement of the rotary decoration interferes with the timepiece mechanism, so that the accurate timekeeping operation cannot be performed and the time display is confused. Inconvenience has occurred.

That is, during the reversing movement in which the rotary ornament switches its rotating direction from one direction to the other, not only the momentum due to the weight of the rotary ornament but also the rotational moment amount due to the shape of the rotary ornament is added, and both of them are cancelled. A driving force for rotating in the opposite direction is required. For this reason, at the time of reversal of the rotating decoration, these become excessive loads on the timepiece mechanism, and the driving force of the timepiece mechanism is reduced, thereby hindering accurate timekeeping operation.

Further, in particular, when the rotary ornament excessively rotates due to an external force or the like, there is a problem that the swing lever, which is the swing mechanism of the rotary ornament mechanism, is excessively bent and caught, and the entire timepiece stops.

Further, if the weight of the rotary decoration is limited in order to avoid such a problem, there is a disadvantage that a high-quality rotary decoration cannot be constructed by using a material such as a heavy crystal.

Therefore, the present invention provides a rotary decoration mechanism capable of performing accurate timekeeping by reducing the rotational moment of inertia during the reversing motion of the rotary decoration and preventing the moment from interfering with the timepiece mechanism. It is also an object of the present invention to provide a regulation lever mold used for manufacturing a regulation lever separately provided in the rotary decoration mechanism.

In addition, since the reversing operation of the rotary ornament is supported and the weight limit of the rotary ornament is relaxed, various decorative members are added or a heavy material such as crystal is used, so that various kinds of rotation are possible. A decoration can be used to improve the appearance and enhance the commercial value.

Further, a plurality of restricting levers having different wall thicknesses or widths are prepared, and one having a wall thickness or a width suitable for the elastic restoring force is selected from the plurality of restricting levers having different wall thicknesses or widths. Since it is selected and used, for example, when a swing angle is small or a heavy object is desired to be turned, a restriction lever having a large wall thickness or width can be used, and in the opposite case, a restriction lever having a small wall thickness or width can be used. Can be used.
In this way, most of the other components of the rotary ornament can be left as they are, and only the rotation around the regulating lever can be replaced.

In view of changing the thickness or width of a part of the restriction lever, it means that both the thickness and the width of the restriction lever which are usually provided are slightly larger and slightly smaller.

Therefore, according to the invention of the second claim of the present application,

Next, the operation of the rotary decoration mechanism 15 will be described.

That is, when the eccentric cam 29 rotates counterclockwise in the figure from the initial state as shown in FIG. 5A, the eccentric movement of the pin 29a of the eccentric cam 29 causes
The swing lever 30 swings counterclockwise as shown in FIG. Then, the crown wheel 32 is rotated clockwise by the comb tooth 30c at the tip of the swing lever 30, the rotation of the crown wheel 32 is transmitted to the decorative drive pinion wheel 33, and the decorative drive pinion wheel 33 moves leftward in the drawing.

Next, as shown in FIG. 5C, when the swing lever 30 approaches the swing limit as the eccentric cam 29 approaches 1/4 rotation, the motion of the swing lever 30 follows. The tip of the regulating lever 31 comes into contact with the stopper 34, and the intermediate portion of the regulating lever 31 bends. At this time, the elastic deformation restoring force of the regulating lever 31 acts in the direction opposite to the swinging direction of the swinging lever 30, and is strengthened as it approaches the swinging limit. As a result, when the oscillating limit is reached and the rotary ornament 10 is reversed, the elastic restoring force of the regulating lever 31 is maximized, and the maximum elastic restoring force can reduce the rotational moment of the rotary ornament 10 and the moment. Is the clock mechanism 1
4 can be prevented from adversely affecting the driving force. That is, when the rotating decoration 10 performs a reversing operation,
Immediately before the reversal, it works in the reverse direction to the rotation direction, and immediately after the reversal, it works in the forward direction, thus assisting the reversal movement of the rotary ornament 10.

Then, with the subsequent rotation of the eccentric cam 29, the intermediate state shown in FIG.
As shown in (e), the eccentric cam 29 is in a state of half-turn. Thereafter, with the subsequent half rotation of the eccentric cam 29,
The above-described operation is performed in the opposite direction, and
0 performs a reversing motion. Finally, the eccentric cam 29 makes one rotation,
Returning to the initial rotation position, the state becomes as shown in FIG. Such a series of operations is repeated every one rotation of the eccentric cam 29, and the periodic reversal movement of the rotary decoration 10 is continued.

In the rotary decoration mechanism 15 described above, when the swing lever 30 swings to the maximum extent, the regulating lever 31 similarly swings, and the stopper 34 is inserted into the engaging hole at the tip.
The elastic deformation of the intermediate portion of the regulating lever 31 due to the contact with the elastic deformation depends on the thickness of the intermediate portion of the regulating lever 31. Therefore, a plurality of restricting levers 31 having different wall thicknesses are prepared, and one of the plurality of restricting levers having different wall thicknesses is selected to rotate the rotary decoration mechanism 1.
5 is used.

FIG. 6 shows a die 40 for manufacturing the swing lever 30 and the regulating lever 31 of the rotary decoration mechanism. Of the die 40, a die portion 41 corresponding to a part of the regulating lever 31 is shown. As shown in FIG. 7, it is formed in a nested structure.

The mold part 41 relating to the nesting structure is a mold to be mounted on the fixed mold of the movable mold 40a and the fixed mold 40b, and has a space 43 which is substantially equal to the regulating lever 31. A nest 42 and a second nest 44 mounted in the space 43 of the first nest 42 are provided. The second insert 44 is provided so that its position can be changed in the direction of the movable die so as to be used for manufacturing a plurality of regulating levers having different wall thicknesses.

The position of the second insert 44 shown in (1) is the same as the restriction lever 3
The thickness of 1 is formed to a thickness that is normally used.
The position of the second insert 44 shown in (2) is the same as the restriction lever 3
The wall thickness of No. 1 is made thicker than the thickness normally used, and the position of the second nesting 44 shown in FIG. 7 (3) is formed so that the thickness of the regulating lever 31 is thinner than the thickness normally used. Is.

As described above, a plurality of restricting levers 31 having different wall thicknesses are prepared, and one having a wall thickness suitable for the elastic restoring force is selected from the plurality of restricting levers having different wall thicknesses. Since it is used, for example, when it is desired to reduce the swing angle or to rotate a heavy object, a restriction lever having a large wall thickness can be used, and in the opposite case, a restriction lever having a small wall thickness can be used. Therefore, it can be implemented by exchanging only around the regulating lever while leaving most other components of the rotary decoration.

FIG. 8 shows another example of the nested structure.

The mold part 41 relating to this nesting structure is a mold to be mounted on the fixed mold of the movable mold 40a and the fixed mold 40b, and has a space 43 substantially equal to the regulating lever 31 as in the previous example. The first nesting 42 and the second nesting 4 mounted in the space 43 of the first nesting 42.
4 is provided. A plurality of second nests 44 having different sizes are prepared so as to be used for manufacturing a plurality of regulating levers having different wall thicknesses.

In this example, similarly to the previous example, the lid member 45 is attached to the first and second nests 42 and 44, and the bolt 46 is inserted from the lid member 45 to fix the second nest 44. . For example, the position of the second insert 44 shown in FIG. 8 (1) forms the wall thickness of the regulating lever 31 to a normally used thickness, and the position of the second insert 44 shown in FIG. 8 (2). Is formed so that the thickness of the restriction lever 31 is thicker than the thickness normally used, and the second nesting 44 shown in FIG.
The position of is to make the wall thickness of the regulating lever 31 thinner than the thickness normally used.

As described above, a plurality of restricting levers 31 having different wall thicknesses are prepared, and one having a wall thickness suitable for the elastic restoring force is selected from the plurality of restricting levers having different wall thicknesses. Since it is used, if a swing angle is to be made small or a heavy object is to be turned as described above, a thick regulation lever can be used, and in the opposite case, a thin regulation lever can be used. it can. Therefore, most of the other components of the rotary ornament can be left as they are, and only the rotation around the regulating lever can be replaced.

As described above, according to this embodiment, the regulation lever is fixed to the swing lever for rotating the support shaft of the rotary ornament, and the stopper for regulating the swing angle of the regulation lever is provided. As a result, when the swing lever is maximally swung, the regulation lever comes into contact with the stopper and the regulation lever is elastically deformed. The elastic restoring force of the restriction lever can reduce the moment of inertia caused by the rotary ornament, and the driving force of the rocking lever required by the timepiece mechanism at the time of reversing can be reduced. That is, when the rotating ornament reverses, the elastic force acts in the direction opposite to the rotating direction immediately before the inversion, and in the forward direction immediately after the inversion,
It will support the reversing movement of the rotating ornament. Therefore, since the rotating decoration can perform a slow motion that smoothly stops and starts to move, it is possible to provide an elegant luxury decoration rotating clock.

Further, by the regulation lever and the stopper,
Since the rotation decoration can be prevented from over-rotating at the time of starting or operation, the drive mechanism can be protected and safety can be improved.

Further, since the reversing operation of the rotary ornament is supported and the weight limit of the rotary ornament is relaxed, a wide variety of rotations can be achieved by increasing the number of decorative members or using a heavy material such as crystal. A decoration can be used to improve the appearance and enhance the commercial value.

Furthermore, in the present embodiment, a plurality of regulating levers having different wall thicknesses are prepared, and one having a wall thickness suitable for the elastic restoring force is selected from the plurality of regulating levers having different wall thicknesses. As described above, if you want to reduce the swing angle or turn a heavy object, you can use a restriction lever with a large wall thickness, and in the opposite case, you can use a restriction lever with a small wall thickness. be able to. Therefore,
It can be implemented by exchanging only around the restriction lever while leaving most other components of the rotary ornament as they are.

In the above example, the second nesting 44 is
To be used for manufacturing multiple control levers with different wall thicknesses,
A plurality of different sizes are prepared so that the second nesting member 44 is provided so that its position can be changed in the direction of the movable mold, and the second nesting 44 is used for manufacturing a plurality of regulating levers having different wall thicknesses. However, the present invention is not limited to this, and it is possible to provide a plurality of restriction levers having different positions or different sizes so as to be used for manufacturing a plurality of restriction levers having different widths.
