Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an operation mechanism of a Karakuri doll used for a mechanical clock or the like.

[0002]

[Prior Art]

 Generally, as a karakuri doll used for mechanical clocks such as equipment clocks, heads, arms, legs, etc., which are separate parts, are attached to the body of the doll, and each of these parts is placed in the body of the drive mechanism. Are known to operate. However, an operating mechanism consisting of a motor and a cam is stored in a limited space inside the doll body, and each part is driven by these mechanisms to perform a predetermined operation, so a large-sized drive mechanism is used. There is a problem that the operation of each part is restricted because a complicated one cannot be used. In particular, the mechanism for standing and sitting is to support the heavy weight of the moving mechanism of each of these parts in addition to the weight of the doll itself. There is a problem that it takes up the space of.

[0003] Therefore, there is known a doll body which is vertically moved by an externally provided drive mechanism so that the doll body is allowed to stand and sit. Also, in this case, by providing an elastic body such as a leaf spring or a spring that is extended on the indirect part of the knee, the legs are naturally extended from the bent state by the weight of the legs when sitting and standing. On the other hand, the knee joint part is flexed by the elastic restoring force of this elastic body from the standing up to the seating so that the leg can be flexed smoothly. For this reason, it is necessary that the elastic body provided at the knee joint has an elastic strength that is appropriately balanced with the weight of the doll's leg.

[0004]

[Problems to be solved by the device]

 However, according to the above-mentioned conventional drive mechanism, it is necessary to design each doll such as resetting the strength of this elastic body for each doll with a different leg weight, which is troublesome and time-consuming. As a result, a mounting member for this elastic body is required, and the number of parts increases, so that there is a disadvantage that cost cannot be reduced.

Further, if the standing operation is repeatedly continued for a long period of time, the elastic force of the elastic body is reduced, which may cause a malfunction, and there is a case in which the durability cannot be sufficiently secured.

Therefore, an object of the present invention is to provide an operation mechanism of a charakuri doll that has a simple configuration that does not require an elastic member and that causes a doll whose leg can be bent to stand up and sit down.

[0007]

[Means for Solving the Problems]

 The operation mechanism of the character doll according to the present invention comprises a three-dimensional object having an arbitrary shape, a doll drive mechanism housed in the three-dimensional object, and a doll attached to the drive mechanism via a support arm. In the movement mechanism of the Karakuri doll, in which the doll moves up and down by the drive mechanism and the leg of the doll bends, the leg has three bending fulcrums and the middle bending fulcrum is It is located on the opposite side of the three-dimensional object with respect to the straight line connecting the other bending fulcrums in.

[0008]

[Action]

 Therefore, according to the present invention, since the mechanism for moving the doll up and down is provided outside and the connecting fulcrum of the middle joint of the leg is offset, the doll's sitting and standing movements are made, so that This creates an extra space in the space, and it is possible to increase the size of another drive mechanism housed in this space.

Further, by providing the intermediate flexion fulcrum of the leg portion when the leg is extended by displacing it in a bending direction from a straight line connecting other fulcrums, the doll is in a standing state, and the leg portion has a straight line in appearance. Even if it is extended in a straight line, the joint fulcrums along the top and bottom are in the middle of extension without being aligned, so the legs can be bent immediately, and elastic bodies for bending the leg joints are not required, and the natural leg The bending operation of the part becomes possible.

[0010]

【Example】

 The present invention will be described below based on the embodiment shown in FIGS. As shown in FIG. 1 and FIG. 2, the motion mechanism 1 of the character doll according to the present embodiment is a three-dimensional object 3 placed on a base floor 2 and a doll driving mechanism housed in the three-dimensional object 3. 4 and a doll body 6 attached to the drive mechanism 4 via a support arm 5. Then, the doll drive mechanism 4 moves the doll body 6 up and down, so that the doll 6 sits on the three-dimensional object 3 or stands up from the three-dimensional object 3 (shown by a virtual line in the figure).

The three-dimensional object 3 is formed into a hollow, substantially rectangular parallelepiped trunk shape, and the doll drive mechanism 4 is housed inside. Further, the height of the upper surface of the three-dimensional object 3 from the floor surface 2 is set lower than the waist of the doll 6, so that the doll 6 can sit and sit on the three-dimensional object 3.

The doll drive mechanism 4 comprises a motor 11, a link mechanism for converting the rotational movement of the motor 11 into vertical movement, and columns 12 and 12 for transmitting the vertical movement to drive the doll 6 up and down. It is configured. That is, the two inner cylinders 13 and 13 are vertically installed inside the upper surface of the three-dimensional object 3, and the support columns 12 and 12 are slidably inserted into the guide cylinders 13 and 13. Can only move up and down. Further, a support arm 5 having its tip attached to the rear side of the body portion 7 of the doll 6 is fixed to the upper ends of the columns 12, 12. A hanging metal member 14 is fixed to the lower ends of the columns 12, 12, and a protruding shaft 14a is fixed to the hanging metal member 14. On the other hand, a rotary disk 15 is attached to the tip of the rotary shaft 11a of the motor 11, and the protruding shaft 15a is fixed to the eccentric position on the front surface of the disk 15. One end of the long rod-shaped connecting member 16 is pivotally attached to the protruding shaft 15a of the disc 15, and the other end is pivotally attached to the protruding shaft 14a of the hanging metal member 14. Therefore, the rotation of the motor 11 causes the disk 15 to rotate, and this rotational movement is converted into vertical movement by the connecting member 16 and the guide tubes 13 and 13, so that the columns 12 and 12 are guided along the guide tubes 13 and 13. It vertically moves up and down, and the body portion 7 of the doll 6 is driven up and down via the support arm 5.

The doll body 6 is configured such that a head portion 8, a right arm portion 9 a, a left arm portion 9 b, and a leg portion 10, which are separately provided, are attached to a body portion 7. .. The head portion 8 swings to the left and right by a motor mechanism (not shown) built in the body portion 7. Similarly, the right arm portion 9a is configured to swing up and down by a built-in motor mechanism (not shown). Further, the leg portion 10 is composed of three cylindrical members, and the first member 21 (thigh) whose upper end is connected to the lower end of the body portion 7 by the pin 20 and the lower end of the first member 21 Is composed of a second member 23 (shin part) connected to the pin 22 and a third member 25 (heel part) connected to the lower end of the second member 23 by the pin 24. By the way, when standing up from the sitting state, the body part 7 is lifted upward, and the leg part 10 naturally expands from the bent state due to the weight of the leg part 10 and the leg part 10 is unreasonable. Instead, it becomes a straight line. However, when the standing leg 10 is bent from the straight state to the seated bent state, the intermediate joint of the extended leg 10 is not bent in a predetermined direction and the joint portion and the leg members 21 and 23 are damaged. May occur. Therefore, according to the present invention, when the leg is extended, the intermediate pin fulcrum of the leg 10 is connected from the line connecting the pin fulcrum A, which is the fulcrum of attachment of the upper leg 10 to the body 7, and the lower pin fulcrum C. This problem is solved by staggering B.

That is, as shown in FIG. 3 (a), the intermediate pin connection fulcrum B is used as a mounting pin fulcrum A between the upper torso 7 and the leg 10 when the doll 6 stands upright. And the lower pin connection fulcrum C and slide in the leg bending direction (left direction in the figure). That is, as far as the thickness of the members 21 and 23 of the leg 10 allows from the straight line L hanging from the upper pin connection fulcrum A, the doll 6 is moved forward in the forward direction to provide the intermediate pin connection fulcrum B. .. Therefore, even when the legs are extended, the mutual relationships among these fulcrums A, B, C occupy the vertices of a substantially triangular shape. As a result, even when the leg 10 is in a straight line and is in a stretched state, the relationship between the fulcrums A, B and C of the joints is in a straight line as shown in FIG. 3 (a). Since it stays in a bent state in the middle without being lined up, it is possible to immediately return to a deeper bent state (shown in FIG. 3 (b)).

[0015]

[Effect of the device]

 As described above, according to the motion mechanism of the character doll of the present invention, a mechanism for moving the doll body up and down is provided outside and the mutual relational positions of the connection fulcrums of the leg joints are displaced to provide the doll's movement. Since the player sits and stands up, space is created in the body, and the mechanism that drives other heads can be made larger and more complicated, allowing the doll to perform more sophisticated and sophisticated movements. You can

Further, by providing the intermediate connection fulcrum of the leg part when the leg is extended by displacing it in a reverse bending direction from a straight line connecting the other fulcrums, the doll is in a standing state, and the leg part has an external appearance. Even when extended linearly, the joint fulcrums along the top and bottom are in the middle of extension without being aligned, so the leg can be flexed immediately and the leg flexes naturally. Therefore, an elastic body such as a leg bending spring is unnecessary, malfunctions due to the decrease in elastic force can be prevented, the number of parts can be reduced, and durability and cost reduction can improve economic efficiency.
