Are rotatably provided in each case.

[0005] One end of the arm rod 7 is fixed to the left opening door 3b. The arm rod 7 projects into the box at a substantially right angle, and is rotatably connected to the tip of the pigeon seat 9 via a pin 8 at the tip.
The pigeon seat 9 is supported so as to be rotatable within a predetermined angle range, and when the doors 1 are stored in the outer box when the doors 3a and 3b are closed, as shown in FIG. The frame 2 is oriented sideways. And this pigeon seat 9
Has an L-shape, and a direction holding surface portion 9a is formed so that one side thereof is perpendicular to the direction of the tail portion 1a of the pigeon body 1.
The tail 1a of the pigeon 1 comes into contact with a projection 10 formed on the upper surface of the slider 5, whereby the direction of the pigeon 1 is controlled when it retreats. Further, one end of a correction rod 11 that is appropriately bent is fixed to the inner surface of the right opening / closing door 3a, and protrudes inward of the outer box. When the open / close doors 3a and 3b are completely opened, the tip 11a of the correction rod 11 follows from the rear of the dovetail seat 9 of the arm rod 7 which rotates with the left open / close door 3b, and the direction holding surface 9a Is pressed lightly from behind to restrict the direction of the pigeon 1.

In the pigeon clock having such a configuration, the slider 5 is driven at a predetermined time in conjunction with the clock mechanism, and the pair of doors 3a and 3b are opened. The arm rod 7 and the correction rod 11 rotate together by the simultaneous opening operation of the opening / closing doors 3a and 3b. At this time, since the rotation of the arm rod 7 is fast, the correction rod 11
And the pigeon 1 is kept at a standstill as if it was left for a moment, and it is rotated along with the arm rod 7 at the same time, and at the same time, the correction rod 11 is also rotated and its tip 11a is It follows and follows the direction holding surface 9a. When the doors 3a and 3b are completely opened, as shown in FIG. 17, the pigeon 1 jumps out toward the front, and the tip 11a of the straightening rod 11 is opened.
Lightly presses the direction holding surface portion 9a of the pigeon body 9 to regulate and hold the direction of the pigeon body 1 to the front.

When the slider 5 is driven in the returning direction, the door opening / closing bars 6a, 6b pull the opening / closing doors 3a, 3b, respectively, and gradually close. When the door opening and closing bars 6a and 6b close,
The pigeon 1 tries to retreat while rotating together with the left opening / closing door 3b in a posture facing the front differently from the time when the pigeon 1 jumps out. If the pigeon 1 tries to rotate as it is, the head may hit the right opening / closing door 3a.
a is given a slight elasticity, and the tail portion 1a is retracted so as to contact the right side of the projection 10. The pigeon 1 has a tail 1a
While the projection and the projection 10 are in contact with each other, the rotation is restricted while the rotation is restricted, and the contact with the right opening / closing door 3a is prevented. When the contact state between the tail portion 1a and the projection 10 is released, the pigeon 1 returns to the original position in accordance with the rotation of the left opening / closing door 3b in a movement reverse to that at the time of popping out.

[0008]

As described above, the conventional cuckoo clock has the rail 4 for guiding the slider 5 in the front-rear direction when the door is opened and closed. And rail 4
