DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a doll driving mechanism, which is capable of performing a complicated and wide-ranging mechanical operation with a single driving motor as well as a plurality of driving motors. About.

[0002]

2. Description of the Related Art A doll driving mechanism is such that a decorative body such as a doll generally performs a predetermined operation by a driving source such as a motor. For example, a doll driving mechanism (generally called a karakuri mechanism) is used in a mechanical timepiece. is set up. As a mechanism of this kind, there is a decorative body such as a doll installed inside the watch main body or attached to the watch body.
When the hour hand of the watch points to "12" on the dial (when the clock reaches "12"), a mechanism that performs a predetermined mechanism operation is known. In addition, there are various modes of operation of the mechanism, and there are various different modes depending on the size of the mechanical clock. That is, for example, a doll or the like that appears with the door open, a doll that appears, rotates up and down or left and right, or changes its expression, and performs a mechanical action, and at the same time, music box sound and other sound effects are linked And those illuminated by lighting.

In such a doll driving mechanism in which a karakuri doll operates, the greater the number of karakuri operation modes, the more the doll driving mechanism
It is possible to increase interest and attract viewers and increase the value as a product. This mechanism is generally provided by an eccentric cam driven by a motor, an operating rod connected to the eccentric cam, a link mechanism and an operating cam body connected to the operating rod, and These motors, eccentric cams, operating rods,
There has been a need for a set of mechanism mechanisms consisting of a link mechanism and the like.

[0004]

Therefore, in the conventional doll driving mechanism, a mechanism for operating the doll is required which includes a motor, an eccentric cam, an operating rod, a link mechanism, etc., corresponding to one of the dolls. Therefore, when trying to increase the number of mechanism mechanisms, a large number of mechanism mechanisms are used to increase the size of the mechanism mechanism, the mechanism itself becomes large, the structure becomes complicated, and the cost increases. Was inconvenient.

The present invention has been made in view of the above circumstances, and particularly provides a doll driving mechanism capable of performing a karakuri operation with a complicated and wide operating range even with a single driving motor.

[0006]

According to the present invention, there is provided a doll driving mechanism in which a doll is mounted on a stage and the doll is operated by a driving motor, wherein a rotating member drivingly linked to the driving motor; Are placed on top of each other,
The base end portion is rotatably supported by a member different from the rotating member, and a rotating cam member having a doll disposed at a distal end portion thereof and an elastic member for elastically biasing the rotating cam member in a predetermined direction. A body, a projection provided at an eccentric position of the rotation member, and a cam groove provided on the rotation cam member, the cam groove engaging with the projection and moving the rotation of the rotation cam member by a predetermined amount by the elastic body. And a rotating member is provided by the drive motor.
The projection and the cam groove which rotate with this when rotated
And elasticity of the elastic body to the rotating cam member.
The biasing restricts the operation of the rotating cam member, and
This is a doll drive mechanism in which the moving amount and moving speed of the doll change .

[0007]

When the driving motor is driven, the rotating member associated therewith rotates, and the projection of the rotating member also rotates together. Since the projection is engaged with the cam groove of the rotating cam member, the projection forcibly regulates the position of the cam groove as the projection rotates. When the position of the cam groove is regulated, the rotating cam member rotates about its base end as a fulcrum in order to follow the regulation. When the rotating cam member rotates, the doll installed at the tip moves in a predetermined direction.
This movement of the doll returns to the initial position by one rotation of the rotating member.

Further, the movement of the doll depends on the length and the rotation angle of the rotating cam member, and the operating range of the doll can be increased in proportion thereto. On the other hand, the movement of the doll depends on the cam groove, and by providing an appropriate curve, a complicated movement can be brought about.

An elastic body that elastically biases the rotating cam member in a certain direction plays a role in advancing or returning the initial position of the rotating cam member that rotates about the base end, and forcibly restricts the position of the cam groove. It serves to assist the function of the projection to be performed.

Further, since a plurality of rotating members can be operated by a single drive motor, for example, when two or more sets of rotating members and corresponding rotating cam members are provided, the structure is complicated and complicated. The operation of the doll having a large operation area is doubled, and therefore, a karakuri operation having a more complicated and wide operation area can be performed.

In this specification, the term "doll" is not limited to the doll itself, but is used to mean a doll and other ornamental bodies in general.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. 1 and 2, in the doll driving mechanism of the present embodiment, a large number of pipes P, P,... So that the left doll A moves leftward from the center of the stage, and the right doll B moves rightward from the center of the stage. It is configured to return to the initial position after a certain time.

A single drive motor M is provided on the lower rear surface of the stage S. Rotating members 2 and 22 which are driven and linked from the drive motor M via two left and right wheel trains 21 are provided on the left and right sides of the stage S. It is provided directly below. Reference numerals 3 and 23 denote protrusions, which protrude upward in the vicinity of the outer periphery of the rotating members 2 and 22.

Between the stage S and the rotating members 2 and 22, elongated plate-like rotating cam members 4 and 24 that rotate around the back surface of the stage S as a fulcrum are superimposed on the rotating members 2 and 22. The dolls A and B are arranged at the distal ends thereof while being rotatably supported at their base ends 4a and 24a. The rotary cam members 4 and 24 have cam grooves 4b and 24b inside. In this embodiment, the cam grooves 4b and 24b are formed by cutting off portions corresponding to the grooves. In addition to providing the cam grooves 4b and 24b by being cut off in this way, any cam grooves such as concave grooves for guiding the engaging projections 3 and 23 can be appropriately formed.

As described above, the dolls A and B are disposed at the distal ends of the rotating cam members 4 and 24, respectively. The disk-shaped members 5, 2 are rotatably arranged.
The dolls A and B are arranged on the reference numeral 5 respectively.

As shown in FIG. 3, pinions 5b, 25 are provided at the lower ends of the disc-shaped members 5, 25 via shafts 5a, 25a.
b, and when the pinions 5b, 25b rotate, the disk-shaped members 5, 25 also rotate. Further, racks R, R corresponding to the movement trajectories of the pinions 5b, 25b when the rotary cam members 4, 24 rotate are fixed to a support plate N provided below the stage S. ing. Therefore, the rotating cam members 4, 24
Starts rotating from the initial position, the pinions 5b, 25b
Is rotated by the racks R, R, and the disk-shaped members 5, 25 are also rotated. As a result, the dolls A and B, which have been facing the front, rotate as shown by the two-dot chain line in FIG. Thus, it creates the atmosphere of hitting the pipes P, P as if they were holding a hand.

The dolls A and B placed on the disk-shaped members 5 and 25 are placed in arc-shaped notches S1 and S2 of a stage S provided in accordance with the trajectories of the dolls A and B. They are positioned so that they fit together.

The rotary cam members 4 and 24 have elastic members 6 and 26 for elastically biasing the rotary cam member in a predetermined direction (in this embodiment, the initial position). Elastic body 6,26
Although the embodiment uses a coil spring, any other elastic body can be used. As described above, when the rotating cam members 4 and 24 are elastically biased to the initial position by the elastic members 6 and 26, the protrusions 3 and 23 of the rotating members 2 and 22 and the rotating cam member Of said cam grooves 4b, 24b
In the various modes of engagement with the rotary cam members 4, 24, the operation of the rotating cam members 4, 24 can proceed more smoothly than when there is no elastic body. However, when the elastic body is not used, the cam groove is formed relatively long or the cam groove is formed with a large obtuse angle. By doing so, the movement of the rotating cam members 4 and 24 can be brought about without hindrance.

The rotating members 2 and 22 are rotated by the driving motor M as described above. The drive motor M is supplied with a drive current from a power supply unit (for example, a battery) provided in the stage S via a control circuit (not shown) and a switch mechanism L described later, and the operation is controlled. As an example, the control circuit obtains a mechanism operation start time such as an hour from the clock mechanism of the mechanism clock, and based on this,
A drive current is supplied to the drive motor M for a predetermined time to start a mechanism operation. In the vicinity of one of the rotating members 2 and 22 (the right rotating member 22 in the example shown in FIG. 4), a switch mechanism L including first and second contact plates is provided. On the other hand, a notch 22a is formed on the circumference of the rotating member 22. This notch 22a
Is provided at a position facing the switch mechanism L at an initial position of the rotating member 22.

Then, for example, when a drive current is supplied from the control circuit at an hour and the drive motor rotates, the rotating members 2 and
22 starts rotating, the notch 22a of the rotating member 22 is disengaged from the switch mechanism L, and the switch of the switch mechanism is closed, while the output current of the drive motor is supplied via this switch, and Then, the supply of the drive current from the control circuit is stopped. Rotating members 2 and 22 are 1
When rotated, the notch 22a of the rotating member 22 faces the switch mechanism L, the switch of the switch mechanism is opened, the power supply to the drive motor is interrupted, and the drive motor is stopped. By arranging such a switch mechanism L, the rotation of the drive motor M can be controlled without using a relatively expensive limit switch for detecting the rotation end position, so that the cost can be reduced.

Next, the operation of the doll drive mechanism of the present embodiment will be described. First, at a normal time or the like, a control circuit supplies a start-up current to the drive motor M directly for a predetermined period from the power supply unit via the control circuit, the drive motor M rotates, and in response to the rotation of the drive motor M, Then, the rotating members 2 and 22 rotate via the two left and right wheel trains 1 and 21 (FIG. 4). Rotating member 22
Rotates, the switch mechanism L is closed, whereby
Even if the power supply from the control circuit to the drive motor M ends after a predetermined period has elapsed, a drive current is supplied from the power supply unit to the drive motor M via the switch mechanism L, and the drive motor continues to rotate.

From the drive motor M, two left and right wheel trains 1, 21
, The left rotating member 2 rotates clockwise, and the right rotating member 22 rotates counterclockwise, and the protrusions 3 project upward near the outer periphery of the rotating members 2, 22. 23 also rotates in the same direction.

The rotation of the projections 3, 23 is performed by rotating the cam members 4, 4.
24, while rotating with the cam grooves 4b, 24b, the rotating cam members 4, 24 are rotated with their base ends 4a, 24a as rotating fulcrums. The placed dolls A and B are respectively moved. As shown in FIG. 5, the left doll A moves to the left and the right doll B moves to the right from the center of the stage S. In FIG. 5, only the positions of the shoes of the dolls A and B are drawn on the disk-shaped members 5 and 25, and the dolls themselves are not shown (the same applies to the following figures).

At this time, the pinions 5b, 25b of the disk-shaped members 5, 25 on which the dolls A, B are arranged are connected to the racks R, R
, And at the same time, the disk-shaped members 5 and 25 also rotate, so that the dolls A and B facing the front at the initial position rotate and face the pipes P and P. Therefore, as described above, the operation of the rotating cam members 4 and 24 is
It creates the appearance of hitting the pipes P, P with a knuckle held in hand.

In this embodiment, as described above, the left doll A moves rightward from the center of the stage, and the right doll B moves rightward from the center of the stage, and returns to the initial position after a predetermined time. In addition to the predetermined reciprocating motion,
They move while performing large and small reciprocating operations to the left and right, respectively.

After the dolls A and B facing the front rotate and face the pipes P and P (FIG. 5), the projections 3 and 23 of the rotating cam members are rotated by the rotation of the rotating members 2 and 22. The dolls A and B are respectively moved left and right while engaging with the cam grooves 4b and 24b (FIG. 6).

From the state shown in FIG. 6, when the right protrusion 23 is located at the location of the laterally extending groove of the right cam groove 24b, the right rotating cam member 24 has moved counterclockwise until now. However, it is pulled by the elastic body 26 and moves clockwise as shown in FIG.

When the left projection 3 is located at a position of the laterally extending groove of the right cam groove 4b slightly behind the state shown in FIG. 7, the left rotating cam member 4 has moved clockwise until now. What has been done is pulled by the elastic body 6 and moves counterclockwise as shown in FIG.

Then, as the rotating members 2 and 22 rotate,
The dolls A and B move to the left and right, respectively (FIG. 9). When the rotation of the rotating members 2 and 22 further advances, the rotating cam members 4 and 24 reverse the rotation, and the left doll A moves rightward. , Right doll B
Move leftward (FIG. 10).

When the dolls A and B further approach the center, the pinions 5b and 25b of the disk-shaped members 5 and 25 are again moved to the racks R and 25.
Rotated by R, the disk-shaped members 5, 25 also rotate at the same time, and the dolls A, B facing the pipes P, P face front, and return to the initial position. Finally, with one rotation of the rotary member 22, the notch 22a of the rotary member faces the switch mechanism L, the switch of the switch mechanism is opened, and the power supply to the drive motor M is interrupted, and the drive motor M is stopped. Stops, thereby ending the operation of one cycle.

In this embodiment, a case where a single drive motor M is used to drively link two rotating members 2 and 22 from the drive motor M via two left and right wheel trains 21 is described. Although described above, other modes such as using more rotating members or using a plurality of drive motors can be adopted. Further, in the embodiment, the rotation cam member is returned to the initial position by the elastic body. However, the rotation cam member may be elastically biased in a direction opposite to the direction. .

As described above, according to the doll driving mechanism of this embodiment, the left doll A moves rightward from the center of the stage, and the right doll B moves rightward from the center of the stage. And at the end, the doll flips, and returns to the initial position after a certain period of time while performing large and small reciprocating movements left and right while moving.Thus, it has a simpler configuration than the conventional one, It is a mechanism that can perform a mechanism operation that is complicated and has a wide operation range.

[0033]

Since the present invention is constructed as described above, the doll swings right and left by the rotating cam member, not only when a plurality of drive motors are used but also with a single drive motor. Moreover, since the doll drive mechanism performs not only a regular movement but also an irregular movement along the cam groove, and is quickly moved by the elastic body, the doll drive mechanism can perform a complicated and wide-ranging karakuri operation. Can be obtained. In particular, when a single drive motor is used, there is an advantage that a complicated operation, which is usually difficult with a single drive motor, can be performed and the cost can be reduced even though the configuration is simple and compact. .

Further, since the rotating cam member and the rotating member for swinging the rotating cam member are provided, the doll can be operated in a wide lateral direction by holding down the depth.

Further, in the case where a plurality of the rotating members and the rotating cam members are provided and the cam grooves are made different, a doll driving mechanism capable of performing a karakuri operation which is more complicated and has a wide operating range is obtained. Can be done.
