(Prior Art) In recent years, interesting mechanical clocks have been installed in plazas, government buildings, etc. where many people gather. This karakuri clock is a clock that, at the hour of the hour, opens the door, reveals a stage, and features dolls and other objects that operate in time with the music, making it a feast for the eyes of viewers. The stage of this conventional karakuri clock is housed within the frame, and in some cases the stage gradually appears outside the frame after the door is opened, and in others the stage built into the frame can be visually seen from the opened opening. . The main function of the door itself was to open and close the opening, and the inside surface was decorated with two-dimensional or three-dimensional patterns to enhance the decorative effect.

(Problems to be solved by the invention) In the stage structure of the conventional mechanical clock,
The space for placing dolls and the like was limited to the width of the opening that was opened and closed by the door, which also limited the number of dolls that could be placed on the stage. Therefore, it is difficult to provide a more colorful stage and increase the interest of viewers by increasing the number of dolls, and it is difficult to increase the doll storage space inside the clock frame even though the number of dolls is small. I had no choice but to take a large amount.
Furthermore, the door opening/closing drive device and the doll's appearance/retraction drive device must be provided separately, resulting in a complicated structure and a lack of splendor on the stage.

The object of the present invention is to provide a stage on the inner surface of a revolving door that opens and closes an opening provided in a watch body frame, and to arrange a movable decoration (such as a doll) on the stage in a well-balanced manner, and to have a wide width. To provide a revolving door capable of arranging a large number of movable ornaments such as dolls.

(Means for Solving the Problems) In order to achieve the above object, the present invention not only informs the time at least on the hour, but also opens and closes an opening provided in the outer frame of a mechanical clock in which a decoration on the stage operates. In the door, a plurality of movable decorations such as dolls are installed on a stage provided on the inner surface and rotatably supported on a pivot near the opening,
The decorative body is characterized in that its weight is well-balanced on the left and right sides of the pivot.

(Example) The present invention will be described in detail below based on the illustrated example.

It is a BB sectional view in FIG. 2.

In the karakuri clock in this embodiment, at a predetermined time (for example, on the hour), a double-door revolving door opens, and first dolls (children) as moving decorations provided on the inner surface of the revolving door appear, and then A doll (conductor) serving as another decorative object emerges from the center outside the frame of the clock body. Thereafter, the conductor greets the audience, the performance is performed, and after the conductor leaves, the revolving door rotates and closes, allowing the children to be housed inside the clock body.

That is, in the figure, 1 is a clock body, and a rotating door 2, 2 in a double-opening mode is provided approximately in the front center of the clock body 1, and an opening 1a is opened and closed by the rotating doors 2, 2. Ru. And the revolving door 2,
2. Stages 4, 4 each having four dolls 3 are integrally attached to the revolving doors 2, 2 on the inner surface of each. At the bottom of each doll 3, a drive unit for the dolls 3 (not shown) is installed. ) are arranged. Reference numerals 5, 5 indicate the pivots of the revolving doors 2, 2, and the dolls 3 are arranged so that three dolls are on the opening side of the pivots 5, 5, and one doll is on the closing side. The weight of the revolving door 2 with respect to the pivot shaft 5 is balanced as it carries a large load.

Of course, changing the number and size of the dolls 3 is a matter of design that can be done arbitrarily, and a conventionally known drive unit equipped with a timer can be used for driving each doll 3. In addition, in the illustrative drawing, two double-sided revolving doors 2, 2 are used, but the revolving door is one
It can also be made into sheets.

In FIG. 4, the opening and closing mechanism of the revolving doors 2, 2 will be explained.

Suspension arms 6, 6 are engaged and connected to the revolving doors 2, 2, and the suspension arms 6, 6 are rotated by a drive motor 7, and the revolving doors 2, 2 are connected to the pivot shafts 5, 6.
It is configured to rotate around 5.

That is, 8 is a drive shaft of the drive motor 7, 9 is a gear driven by the drive shaft 8, 10 is a driven gear to which the rotation of the drive gear 9 is transmitted, and the driven gear 10 is located at the center of the transmission shaft 11. It is fixed externally to the
Transmission gears 12 and 1 are provided at both ends of the transmission shaft 11, respectively.
2 is attached, and the transmission gears 12, 12 are meshed with rotating gears 14, 14 fixed to the pivot shafts 13, 13 of the suspension arms 6, 6. And rollers 15, 1 are attached to the tips of the above-mentioned suspension arms 6, 6.
