Description

[Detailed description of the invention] (Field of industrial application) The present invention is a decorative clock that increases the decorative effect by attaching various decorative objects such as dolls, and in particular, the movement of the decorative objects can also improve the decorative effect. This invention relates to a movable structure for decoration of a decorative watch.

(Prior Art) In recent years, it has become increasingly desirable for this type of decorative watch to have a decorative element that actively moves, rather than simply having decorative properties such as the shape and pattern of the decorative element.

However, in conventional decorative watches with moving decorations, the decorations simply rotate in a circular orbit or simply rotate, making monotonous movements that do not meet the diversifying needs of consumers. It was not a sufficient response.

(Problems to be Solved by the Invention) Therefore, the purpose of the present invention is to solve the above-mentioned conventional problems, to enable the decorative body to make precise movements, and to provide a variety of decorative clocks. The goal is to fully meet the changing needs of consumers.

(Means for trying to solve the problem) Therefore, in order to achieve this purpose, the present invention has a main shaft that is connected to the drive device of the watch and rotates,
A shaft attached at right angles to the main shaft, a main shaft arm attached to the main shaft above the shaft, and a diagonal guide hole formed in the arm part rotatably supported by both ends of the shaft and extending from side to side. A lever, a wavy cam that contacts the tip of a leg extending downward from the lever, and a wavy cam that rotates along the shape of the cam, engages with the guide hole of the lever, and is supported by the main shaft arm for vertical movement. The movable shaft is characterized by comprising a movable shaft and a decoration attached to the upper end of the movable shaft.

(Example) Hereinafter, the present invention will be described in detail based on an example of the present invention shown in the drawings.

FIG. 1 is a front view showing the ornament movable structure of the ornamental timepiece of the present invention. What is indicated by code 2 in the figure is
This is a main shaft that is connected to a drive device for a watch body (not shown) and rotates. This main shaft is supported by the upper plate 4 at its upper end. As shown in FIG. 2, a central shaft 6 is attached at right angles to the intermediate portion of the main shaft 2, and levers 8 are rotatably supported at both ends of the central shaft 6.
This lever has a substantially T-shape as shown in FIG. 1, and the leg portion 10 extends slightly inclined toward the right side in the figure in order to easily follow a cam 12, which will be described later.
Its tip is in contact with the cam 12 below. This cam 12 has a leg portion 10 with continuous gentle unevenness.
The tip is formed in a wavy shape so that it can run along the surface.

On the other hand, diagonal guide holes 16 are formed in both arm portions 14 of the lever 8 . A movable shaft 18 is engaged with each of the oblique guide holes 16 . The movable shafts 18 are supported by pipes 20, respectively.
The pipe 20 is attached to a spindle arm 19 held on the spindle 2.

Then, an appropriately shaped decoration such as a doll 22 is attached to the upper end of each movable shaft 18.

In the present invention having the above structure, the main shaft 2 is now rotated as shown by the arrow in FIG. Then, the lever 8 rotates around the central shaft 6 along the wavy uneven shape of the cam 12 at its leg portion 10 . At this time, since the lever 8 rotates along the unevenness of the cam 12, the arm portion 1 is rotated as shown in FIGS. 3 and 4.
4 swings, and accordingly, the movable shaft 18 that engages with the arm 14 moves up and down alternately in the left and right arms 14, thereby causing the doll 22 to move up and down continuously. In this way, the rotational movement of the main shaft 2 is achieved by causing the movable shaft 18 to continuously move up and down using the lever 8 and the wave-like cam 12, and also to rotate around the main shaft 2, so that the doll 22 can be moved up and down and rotated in various ways. to satisfy the decorative quality of the watch.

In the above-mentioned embodiment, four dolls 22 as decorations are attached as shown in the figure, but for example, the pipe 20 may be further attached to the main shaft arm 19, or the lever 8 may be further attached to add more dolls 22. You can also make it even more diversified. Further, the number of dolls 22 can be reduced by forming the lever 8 in an L-shape and using only one arm portion 14.

As shown in FIGS. 5 and 6, the doll 22 can also be rotated using a rudder 34 having a plurality of radially extending engagement protrusions 32. This rudder is attached to the upper end of the movable shaft 18.
In this embodiment, projections 36 are irregularly protruded from the upper plate 4, so that the engagement projections 32 come into contact with the projections 36 when the rudder 34 passes through the guide groove 24. Therefore, the rudder 34 rotates each time it hits each protrusion 36, which causes the doll 22 to rotate in a complicated manner.

Furthermore, in addition to the rudder 34 shown in FIGS. 5 and 6 as another embodiment of the present invention, a wheel train 38 as shown in FIG. 7 is used to obtain a more complex movement of the decorative body. It can also be configured. In this embodiment, a shaft gear 40 is attached to the upper end of a movable shaft 18 to which a rudder 34 is attached, and support gears 42 are meshed with both sides of this shaft gear 40 to form a wheel train 38. The dolls 22 are mounted on the support gears 42, respectively. This wheel train 38 is housed in a box stand 44 that supports the doll 22 on the upper side. According to this embodiment, in addition to the change in rotation caused by the rudder 34, the supporting gears 42 rotate in opposite directions around the shaft gear 40, so that the doll 22 can move more precisely. In this case, the configuration of the wheel train, the number of teeth of the gears, etc. can be changed as appropriate to arbitrarily diversify the rotational direction and rotational speed.

The present invention can be attached to a clock with other devices, such as a music box clock, to give it a sense of fun and luxury.

(Effects of the invention) According to the invention, on the basis of precisely moving the ornaments of dolls and other objects up and down without using any complicated mechanism, the ornaments can be made to have various interesting features such as rotating irregularly. Since it is possible to easily obtain the desired movement, it becomes possible to fully meet the diversifying needs of consumers even in decorative watches.
