In FIG. 1, a spring 21 has a spring hook 22b having one end provided on a spring column 20 and the other end provided on a stage storage section 22.
The stage 1 is always elastically urged in the closing direction by the spring force of the spring 21. That is, when the stage 1 described later is closed,
Is smoothly urged by the spring force of the spring 21 even if the motor driving force is relatively small.

In FIGS. 1 and 2, reference numeral 23 denotes a guide member for guiding the movement of the doll support 7 described later. In FIGS. 5 and 6, reference numeral 26 denotes a tension pulley that applies tension to the timing belt 4.

Next, the structure and movement of the doll support 7 and the doll 8 provided on the doll support 7 will be described.

The doll support 7 is provided so as to be able to reciprocate between the base and the tip of the stage 1 and travels with the rotation of the timing belt 4 described above. Doll support stand 7
Is provided with a rolling roller 7a at a lower portion, and moves along the lower surface of the pair of guide members 23 of the stage 1. The pulley 5 for a timing belt provided on the doll support 7 is driven by a timing belt. Meshed with the belt 4 (FIG. 1,
4 and 6).

Further, as shown in FIG. 4, the doll support 7 is provided with a pair of rolling bearings 6, 6 'and a shaft 6a rotatably supported between the bearings 6, 6'. , This axis 6
The timing belt pulley 5 is fixed to the outside of a, and the cam bodies 6b, 6b are fixed to the center part.

Reference numeral 8b denotes a connecting rod for operating the leg and the arm which can be extended and contracted. That is, the connecting rods 8b, 8b are provided corresponding to the two legs and the arms of the doll, and the lower ends thereof are respectively engaged with the cam bodies 6b, 6b, and the upper portions thereof are the legs of the doll 8. Part and arm. Therefore,
When the cams 6b, 6b rotate, the connecting rods 8b, 8b move up and down, whereby the legs and arms of the doll 8 perform the expansion and contraction operation.

In this embodiment, the shaft 6a having the timing belt pulley 5 and the cam bodies 6b, 6b is connected to the connecting rod 8
Due to the engagement of b and 8b, a load (brake) is applied to its rotation. When a load is applied to the timing belt pulley 5 that meshes with the timing belt 4, the timing belt pulley 5 does not rotate by the timing belt 4 when the timing belt 4 rotates. As it were, the doll support 7 accompanies the rotation of the timing belt 4. At this time, the outer ring of the rolling bearings 6, 6 'rotates while moving along the guides 1a, 1a' of the stage 1.

In this way, when the doll support 7 travels and reaches the front end of the stage 1, the travel of the doll support 7 must be stopped. It is forcibly rotated. At this time, the inner rings of the rolling bearings 6, 6 'rotate. When the pulley 5 for the timing belt rotates, as described above, the operation of the doll 8, that is, the expansion and contraction operation of the legs and the arms in this example, starts.

When the motor rotates in the reverse direction, no external force acts to stop the movement of the doll support 7, so that the timing belt pulley 5 is not rotated by the timing belt 4 due to the load as described above. As a result, with the rotation of the timing belt 4, the doll support 7 accompanies in the direction of the base of the stage 1.

When the doll support 7 reaches the base of the stage 1, the movement of the doll support 7 stops. At this time, the pulley 5 for the timing belt, which is about to rotate with the rotation of the timing belt 4,
(In this example, the block provided on the stage storage section 22), the rotation of which is restricted, so that the timing belt 4 does not forcibly rotate the pulley 5 for the timing belt. As will be described later, the energy of the rotation by the timing belt 4 is transmitted to the stage storage unit 2 by the stage 1.
2 (the closing operation of the stage 1).

At the base of the stage 1, the pair of guide members 23 are cut out at intervals corresponding to the shape of the doll support 7. That is, the doll support 7
Is located at the base of the stage 1, the doll support 7 is out of the regulation of the guide members 23, 23.
As will be described later, when the stage 1 is opened and closed with respect to the stage storage unit 22, the doll support 7 is provided with holes 7b provided in the doll support 7.
Since the engaging member 15 is engaged with the stage 1, the horizontal state is maintained, so that this horizontal state, that is, the linkage between the non-rotating doll support 7 and the stage 1 is released.

FIGS. 6 to 8 are side views showing the stage storage section 22 of the mechanism of the present embodiment and the stage 1, the doll support 7 and the doll 8 stored therein, and FIG. 7 shows the stage 1 in a half-open state, and FIG. 8 shows the stage 1 in an open state.

In these figures, the stage 1 has a base shaft 2a which is supported by the stage storage 22 as described above.
The fulcrum is provided so that it can be opened and closed.

The engaging member 15 is provided at the tip of a plurality of links 16 and 17 serving as a link mechanism provided in the stage storage section 22, and one of the links 16 is connected to the link 16 and the stage storage section. It is always elastically biased in the direction of the stage 1 by a spring 25 provided between the part 22. Therefore, as shown in FIGS. 6 to 8, when the doll support 7 is located at the base of the stage 1 when the stage 1 is opened and closed, the engaging member 15 is fitted into the hole 7 b provided in the doll support 7. Engaged.

As shown in FIGS. 6 to 8, since the engaging member 15 is engaged with the hole 7b provided in the doll support 7, the doll support 7 can be moved regardless of the opening and closing movement of the stage 1. Maintain a horizontal position.

That is, the link mechanism including the engaging member 15 to be engaged with the doll support 7 and the plurality of links 16 and 17 supporting the engaging member 15 on the stage provides the decorative body 8 when the stage 1 rotates. This is a posture maintaining means for maintaining the posture of the stage 1 separately from the stage 1, whereby the stage 1 and the doll 8 are efficiently stored in the stage storage 22. By maintaining the posture of the doll 8 separately from the stage 1 by the posture maintaining means, the stage 1 and the doll 8 are stored in a small space as compared with the case where the doll 8 rotates together with the stage 1. Further, according to the link mechanism, the doll 8 and the engaging member 1
5 moves while being held in a predetermined direction during the stage 1 rotation.

When the doll support 7 reaches the base shown in FIG. 8 from the position of the tip of the stage 1 shown in FIG. 1, for example, the engaging member 15 is inserted into the hole 7b of the doll support 7 as described above. Engage with the cam body 6b of the doll support 7 at that time.
However, the rotation of the stage 1 is restricted by contacting a block (not shown) provided on the stage 1.

In the above example, switches and sensors such as limit switches are installed at various places. For example, as shown in FIG.
4. As shown in FIG. 6, a switch 27 and the like at the upper part of the stage storage section 22 are provided.

Next, in this example, the stage 1 is opened from the state in which the stage 1 is stored in the stage storage section 22, and then the doll support 7 protrudes, and the doll operates at the tip of the stage 1. A series of movements will be described.

When the motor rotates in the state shown in FIG. 6, the rotational driving force of the motor is transmitted to the pulley 2 provided at the base of the stage 1 via the gears 12 and 13.

The rotational driving force transmitted to the pulley 2 attempts to rotate the timing belt 4 wound between the pulleys 2 and 3. At this time, the cam body 6b comes into contact with the stage block (stopper body) and its rotation is regulated.
The timing belt pulley 5 linked to the timing belt 4 does not rotate. Since the timing belt pulley 5 does not rotate, the timing belt 4 also does not rotate. Therefore, the energy of the rotation applied to the timing belt 4 acts as a means for rotating the stage 1 in the opening direction from the stage storage 22 (opening operation of the stage 1) (see FIG. 7).

At this time, since the engaging member 15 is engaged with the hole 7b provided in the doll support 7, the doll support 7 is kept horizontal regardless of the opening operation of the stage 1.

When the stage 1 is opened and reaches a substantially horizontal state, the stopper pin 19 comes into contact with the stopper 22a, and the opening operation of the stage 1 is stopped at that position.

The opening operation of the stage 1 is performed with the base shaft 2a as a fulcrum, and the guide members 23, 23
The notch portion also rotates, and the doll support 7 located in the notch portion also rotates with the rotation of the notch portion. During this rotation, the engaging member 15 is engaged with the hole 7b of the doll supporting table 7, so that the doll supporting table 7 maintains a horizontal state.

When the opening operation of the stage 1 is stopped, the doll support 7 rotates as described above, and thus moves to a position where the stage 1 slightly protrudes. Due to the movement, the cam body 6b of the doll support 7 is released from contact with the block of the stage 1, and the state in which rotation has been restricted until now is released. Accordingly, the rotation of the motor causes the pulley 2 to rotate, and accordingly, the timing belt 4 wound between the pulleys 2 and 3 starts to rotate.

When the timing belt 4 rotates, a load is applied to the timing belt pulley 5 that meshes with the timing belt 4. Therefore, when the timing belt 4 rotates, the timing belt pulley 5 rotates by the timing belt 4. Therefore, the doll support 7 accompanies the rotation of the timing belt 4 while meshing with the timing belt 4.

When the doll support 7 travels and reaches the front end of the stage 1, the movement of the doll support 7 stops, and the timing belt 4 forcibly rotates the pulley 5 for the timing belt. .

When the timing belt pulley 5 rotates, the shaft 6a and the cam bodies 6a, 6a associated therewith rotate, and the connecting rods 8b, 8b engaged with the cam bodies 6a, 6a move up and down. The leg and the arm of the doll 8 perform a telescopic operation.

When the doll support 7 reaches the front end of the stage 1, the doll support 7 contacts the switch 14 and is turned on. When the switch 14 is turned on, the motor rotates reversely after a lapse of a predetermined time.

When the motor rotates in the reverse direction, no external force acts to stop the movement of the doll support table 7, so that the timing belt pulley 5 is not rotated by the timing belt 4 due to the load as described above. Therefore, the timing belt 4
The doll support 7 accompanies the base 1 of the stage 1 with the rotation of.

When the doll support 7 reaches the base of the stage 1, the doll support 7 stops running. At this time, since the cam body 6b abuts on the block of the stage 1 and the rotation thereof is regulated, the timing belt pulley 5 that is about to rotate with the rotation of the timing belt 4 is regulated. No forced rotation of the pulley 5 occurs. The energy of the rotation by the timing belt 4 acts to store the stage 1 in the stage storage unit 22, and causes the stage 1 to close the stage storage unit 22.

At the base of the stage 1, the pair of guide members 23, 23 are cut out at intervals corresponding to the shape of the doll support 7, so that the stage 1 is
When the doll support 7 is closed, the doll support 7
The engaging member 15 is engaged with the hole 7b provided in the above, and maintains a horizontal state.

When the stage 1 is stored in the stage storage section 22,
The tip of stage 1 abuts on switch 27, thereby stopping the rotation of the motor.

According to the configuration of this embodiment, the opening and closing operation of the stage 1, the movement operation of the doll 8 on the stage 1, and the operation of the doll 8 after the movement operation are sequentially performed by the rotation drive of one motor. Alternatively, the respective operations may be configured such that a motor is arranged at each location and performed by an individual motor.

As described above, according to the mechanism of the present embodiment, since the posture maintaining means for maintaining the posture of the decorative body separately from the stage when the stage is rotated is provided, the stage and the decorative body can be efficiently stored in the stage storage section. And the taste of the operation of the stage and the decorative body can be improved.

That is, by maintaining the posture of the decorative body separately from the stage by the posture maintaining means, the stage and the decorative body can be stored in a small space as compared with the case where the decorative body rotates together with the stage. As a result, the stage storage unit can be reduced in size.

Also, since the stage and the decorative body emerge from the relatively small stage storage section, and the decorative body moving on the stage maintains its posture separately from the stage when the stage is rotated, the mechanism and the ornament are used as a mechanism. Surprisingness can be increased, and the taste can be further improved.

Further, according to the mechanism of the present embodiment, the posture maintaining means supports the engaging member which is engaged with the decorative body or the support of the decorative body when the stage is rotated, and the engaging member in the stage storage portion. Since the link mechanism is provided, when the stage is rotated, the posture of the ornament can be maintained separately from the stage by engaging the ornament with the engaging member.
