Description

[Detailed description of the invention] The present invention relates to an improvement of a device for displaying dolls on table clocks or wall clocks.More specifically, by making the rotational movement of the doll complicated with a simple structure, it is possible to make the doll appear to be playing music (melody). To provide a doll decoration device that appears to be dancing to the music.

In a conventional doll decoration device, a doll equipped with a rotation transmission wheel that transmits rotation from a cam plate is rotatably supported on a rotating table that rotates in a fixed direction at a constant speed, and is displaced from the rotating shaft of the rotating table. The rotation transmission wheel is rotated in forward and reverse directions by being alternately engaged with a first cam for forward rotation located at an outer position of a cam plate fixed to the case and a second cam for reverse rotation located at an inner position. Ta. Therefore, the doll simply repeated forward and reverse rotations with respect to the rotating table, and moved integrally with the rotating table on the circumference around the rotating axis of the rotating table. In this conventional doll decoration device, the doll's motion was limited to very simple rotation and movement on the circumference, so the changes in the doll's motion were unsatisfactory. Furthermore, in music box clocks and clocks with melody that generate melodies in accordance with the movements of the dolls, the rhythm of the melody tends to become monotonous. When a dance-style melody, such as a waltz or tango, is selected, there is a drawback that the puppet's movements cannot match the melody. Therefore, it has been desired to be able to rotate the doll on the turntable in forward and backward directions, to temporarily stop it, and to change the doll's movements from simple circular motion and rotation to complex motions.

The present invention was made to eliminate the drawbacks of conventional devices, and its purpose is to make the moving trajectory of the doll on the rotating table a complex one, rather than a simple circular trajectory. To provide a dancing doll decoration device that can operate in accordance with a melody.

In order to achieve the above-mentioned object, the present invention has been developed so that a doll is mounted on a doll mounting base of a doll rotating body which is rotatably supported on a rotary plate rotated by a drive mechanism. The doll includes a cam plate equipped with a plurality of cam groups that are displaceably mounted and engaged with a first rotation transmission wheel of the doll rotating body to control forward and reverse rotation of the doll rotating body, In addition to rotating the movement forward and backward or temporarily stopping it,
It is characterized by complex movements, not just circular motion or rotation.

Note that the cam group includes pins, gears, and the like.

The present invention will be described below based on an embodiment of the present invention shown in the drawings.

are each composed of one protrusion 40a.

The first embodiment of the present invention is constructed as described above, and its operation will be explained next.

The rotary gear 20 is rotated at a constant speed in a constant direction by the driving gear 26 of the motor, thereby rotating the rotary table 30 at a constant speed in a constant direction. For example, as shown in FIG. 2, when the rotating table 30 is rotated in the direction of arrow Y and the protrusion 38a of the cam wheel 38 of the doll rotating body 32 engages with the protrusion 42a of the second cam 42 of the cam plate 28, the cam The wheel 38 rotates in the direction of arrow N. As a result, the doll 1 moves along the chain line 50 above the rotating table 30 in FIG.
Rotate in the direction of the arrow shown. Then, when the rotary table 30 further rotates in the direction of arrow Y and the protrusion 38a of the cam wheel 38 engages with the first cam 40 of the cam plate 28, the protrusion 38a of the cam wheel 38 comes into contact with the protrusion 40a of the first cam 40. Pressed. As a result, the cam wheel 38
By rotating in the direction of arrow P, the doll mounting base 34 is rotated in the direction of arrow P. Therefore, the doll 1 rotates with respect to the rotating plate 30 in the direction of the arrow shown by the chain line 52.

Since the numbers of protrusions 40a or 42a constituting the protrusion groups A to H of the first cam 40 and the second cam 42 of the cam plate 28 are different, the cam wheel 38 is connected to one of the protrusion groups A to H. By engaging with the doll mounting base 34, the rotation angle of the doll mounting base 34 can be varied. For example, in FIG. 2, the cam wheel 38 is in the protrusion group A.
When engaging with the doll mounting base 34, the rotating base 3
0, the doll 1 rotates approximately 1/3 in the direction of the arrow N, and therefore the doll 1 rotates approximately on the circumference indicated by the chain line 50 in the direction of the arrow.
Can make 1/3 turn. Then, the cam wheel 38 moves to the protrusion group A.
The doll 1 remains temporarily stationary from when it is separated from the doll 1 to when it is engaged with the group of protrusions B. When the cam wheel 38 engages with the protrusion group B, the cam wheel 38 moves approximately 1/4 in the direction of arrow P.
Since it rotates, the doll 1 can rotate approximately 1/4 of a turn in the direction of the arrow on the circumference indicated by the chain line 52 relative to the rotating table 30. Then, the doll 1 is temporarily stopped again, and when the cam wheel 38 engages with the protrusion group C, the doll 1 rotates approximately 11/4 around the circumference indicated by the chain line 56 in the direction of the arrow. Thereafter, in the same way, the cam wheel 38 and the protrusion groups D, F,
By alternately engaging G and H, doll 1
The rotation direction and rotation angle are variable.

As explained above, when the rotary table 30 is rotationally driven by a motor or the like, the cam wheel 38
By engaging any one of the protrusion groups A to H of the cam plate 28, the doll 1 is repeatedly rotated forward and backward at different rotation angles with respect to the rotary table 30.

According to this first embodiment, the doll 1 has a rotary plate 30
In addition to being rotated at a constant speed in a constant direction integrally with the rotation of the doll rotating body 32, the doll rotating body 32 can swing or rotate around the rotation axis 36 of the doll rotating body 32 with respect to the rotating table 30.

In the illustrated first embodiment, the doll rotating body 32
In order to rotate the cam plate 28, a first cam 40 and a second cam 42 each having a plurality of protrusion groups A to H are protruded.
The object of the present invention can be achieved by simply installing only a pin that can be continuously engaged with the cam wheel 38 at the position corresponding to a.

In addition, a normal spur gear is fixed in place of the cam wheel 38, and the first cam 40 and the second cam 4 of the cam plate 28 are fixed.
The object of the present invention is achieved by forming the second protrusions 40a and 42a into toothed portions that can mesh with the spur gear.

Furthermore, a rotor may be fixed instead of the cam wheel 38, and the first cam 40 and the second cam 4 of the cam plate 28 may be fixed.
The object of the present invention is achieved by making only the continuous engagement length of the two protrusion groups A to H a cam surface that can be engaged with the rotor.

Next, a second embodiment of the present invention will be explained based on FIG. 3.

A feature of the second embodiment is that the rotational motion of the doll 1 itself is added to the rotational motion of the doll in the first embodiment. The structure of the doll rotating body 60 and rotating table 62 for achieving the rotational movement of the doll 1 itself is shown in FIG. 3, and the other structures are the same as those in the first embodiment, so detailed explanations are omitted. do.

A toothed portion 62b is provided around the bearing portion 62a of the rotary table 62.
A third rotation transmission wheel 62C is formed. A rotating shaft 72 to which the doll 1 is fixed is rotatably supported on the doll mounting base 70.
A gear body second rotation transmission wheel 74 that can rotate by meshing with the tooth portion 62b is fixed to the gear body. The gear body 74 may be a roller, but in this case, the periphery of the bearing portion 62a is a surface that can be engaged with a roller.

According to the second embodiment, as the doll rotating body 60 rotates or swings, the gear body 74 that meshes with the teeth 62b of the rotating table 62 is rotated forward or backward. Therefore, the doll 1 itself serves as the doll mounting base 7.
It becomes possible to rotate forward or backward relative to zero. Therefore, in addition to the motion of the doll 1 of the first embodiment, a complex doll motion accompanied by forward and reverse rotation of the doll 1 itself can be provided.

As described above in detail, according to the present invention, as the rotating table rotates, the doll can move around the rotation axis of the rotating table in the forward rotation direction or the reverse rotation direction. In other words, the doll mounting base is rotatably supported on the rotation table, and the doll is rotatably supported on the doll mounting base at a displacement with the rotation axis of the base. It can perform rocking motion on the rotating table. In addition, when the base for mounting the doll performs singing motion on the rotating table, if the structure is configured such that forward and reverse rotation can be transmitted from the third rotation transmitting wheel of the rotating table to the second rotation transmitting wheel of the doll, the doll itself can also rotate in both forward and reverse directions. Therefore, the movement form of the doll can be varied to a greater extent than in conventional doll decoration devices, and the movement form of the doll becomes complex.

By generating a melody that matches the movement form of the doll, it appears as if the doll is dancing to the melody. Therefore, by attaching the doll decoration device of the present invention to a clock with a music box or a clock with an electronic melody, it is possible to provide a decorative clock that is fully aurally and visually satisfying, thereby increasing the decorative effect and commercial value of the clock. be able to.
