The embodiment shows that the decorative body 1 reciprocates on the stage 2 and swings the arms 3 and legs 4 as shown in FIGS. First, a brief description will be given. Inside the stage 2, a drive box 6 which can be reciprocally driven along a rail 5 is arranged, and a decorative body 1 which is a rabbit doll is mounted on the drive box 6, and the drive box 6 is used as a decoration body. The operating shaft 8 which can be vertically moved and rotationally driven is projected until it reaches the inside of the barrel 7, and the vertical movement and the rotational motion of the operating shaft 8 cause the arm link 3a and the leg link 4a of the ornamental body 1 to intervene. It is configured to swing the arms 3 and legs 4.

Specifically, the rail 5 is fixed to the stage bottom plate 2 b and the drive box 6 is attached to the rail 5, while the rack 9 is attached in the stage 2 in parallel with the rail 5. In addition, the drive gear 10 provided in the drive box 6 is meshed with the drive gear 10, and the drive gear 10 is rotated, whereby the drive box 6 travels along the rail 5.

The drive box 6 includes a motor 11 in a box frame 6 a, and as shown in FIGS. 4 to 5, the rotation of the motor 11 causes the worm 12, the worm gear 13, the intermediate wheels 14, 15 and the rotary gear 16 to rotate. It is configured to be transmitted to the drive gear 10 via the.

The upper case 6 a of the drive box 6 is formed with a through hole 20 through which the shaft of the rotary gear 16 (hereinafter, referred to as “rotary shaft 19”) penetrates and a through groove 21 through which an operating shaft 8 described later penetrates. The rotary shaft 19 and the actuating shaft 8 move together with the drive box 6 in the long hole A provided in the moving plate 17. The through groove 21 is formed in a semicircular shape centered on the through hole 20.

The drive gear 10 is connected to the rotary shaft 19 via a slip gear 25 so that the drive gear 10 can slip on the rotary shaft 19 when a high load is applied.

The operating shaft 8 is vertically slidable in the axial direction and capable of rotating around the axial line, and a driven gear toothed at the lower end of the operating shaft 8 is engaged with the rotary gear 16. 26 is integrally formed, and the upper end reaches the barrel 7 of the decorative body 1. Further, the driven gear 26 is meshed with the rotary gear 16 so as to be slidable up and down. A spring 27 for urging the operating shaft 8 downward is arranged on the lower surface of the moving plate 17.

On the upper part of the operating shaft 8, the leg links 4 a, 4 a are expanded between the leg links 4 a and 4 a against the urging force of the spring 29, and the arm link 3 a is rocked against the urging force of the spring 28. The bulge portion 30 is formed.

On the other hand, below the operating shaft 8, a rotary pushing rod 31 for pushing up the lower surface of the operating shaft 8 is arranged. Reference numeral 32 denotes a pressing portion provided at an end portion in the stage 2, and the pressing portion 32 has a role of pressing and rotating the rotating push-up rod 31 in the drive box 6 that has moved forward. .. Reference numerals 33 and 34 denote limit switches arranged at both ends of the stage 2.

According to the configuration of the above-described embodiment, the motor 11 is driven to rotate the rotary shaft 19 at the hour, and the drive gear 10 meshed with the rotary gear 16 integral with the rotary shaft 19 is rotated. Be done. As a result, the drive box 6, the moving plate 17, and the barrel 7 are moved along the rail 5 by the rotation of the drive gear 10 meshing with the rack 9.

In the initial stage of rotation of the rotary shaft 19, the barrel 7 rotates along with the rotary shaft 19, and the barrel 7 stops rotating when the operating shaft 8 contacts the end of the through groove 21. As a result, the drive gear 10 is fixed in position with respect to the cam rotary gear 16, and thereafter, the driven gear 26 meshing with the rotary gear 16 and the operating shaft 8 integrated with the driven gear 26 start rotating. ..

The rotation of the actuating shaft 8 causes the bulging portion 30 to rotate, expanding and contracting the leg link 4a, so that the decorative body 1 makes a walking motion. At this time, as shown in FIGS. 7 (A), (B), FIGS. 8 (A), (B), (C), and (D), the arm link 3a is located at a height position above the bulging portion 30. No, therefore no swinging of the arm 3 occurs.

Further, when the drive box 6 further advances along the rail 5, as shown in FIGS. 9 to 11, the rotary push-up rod 31 is pushed and rotated by the pressing portion 32, and the rotary push-up rod 3 is rotated. 1 pushes up the actuating shaft 8, so that the bulge 30 comes to the position where the arm link 3a exists as shown in FIGS. 8 (E) to 8 (H), and this time the arm 3 of the ornament 1 swings. Then, at the end, the drive box 6 comes into contact with one of the limit switches 33 and the forward movement is stopped.

In this embodiment, as described above, the drive gear 10 is attached to the rotary shaft 19 so as to slip with respect to the rotary shaft 19 when the load is high, and the drive box 6 is attached to the limit switch 33. The forward movement is stopped by abutting against. At this time, when the rotation of the rotary shaft 19 is further connected by the operation of the motor 11, the drive gear 10 slips with respect to the rotary shaft 19, and the moving plate 17 and the barrel 7 move due to the stop of the drive box 6. The rotation of the rotary shaft 19, the driven gear 26, and the working shaft 8 can be continued in a state where the rotation is stopped.

When the drive box 6 comes into contact with the limit switch 33 and is stopped from moving, the operating shaft 8 is pushed up, and if the motor 11 continues to rotate in this state, it swells. The portion 30 continues to rotate at the position of the height of the arm link 3a, and the arm 3 is swung.

When the motor 11 is rotated in one direction for the required time and then the motor 11 is rotated in the reverse direction, the rotating shaft 19 rotates in the reverse direction, and the driven gear 26 applies a pressing force in the reverse direction by the teeth of the rotating gear 16. Since it is received, the operating shaft 8 moves in the through groove 21 in the opposite direction, and the operating shaft 8 comes into contact with the other end of the through groove 21. As a result, the barrel 7 is inverted and the ornament 1 is rotated 180 degrees.

In this way, when the barrel 7 rotates 180 degrees, the rotary push-up rod 31 is disengaged from the pressing portion 32, the operating shaft 8 is pushed down by the spring 27, and the bulging portion 30 descends to lower the leg link 4a. 4a, the swing of the arm 3 is stopped and the left and right legs 4 and 4 start to swing. When the rotation shaft 19 starts to rotate in the reverse direction so that the body tube 7 turns 180 degrees and swings the legs 4 and 4, the drive gear 10 attached to the rotation shaft 19 rotates in the reverse direction, and the drive box 6 As a result, the moving plate 17 and the barrel 7 are retracted along the rails 5, and when they are retracted to a predetermined position, the drive box 6 contacts the other limit switch 34 and the rotation of the motor 11 is stopped.
