Description

[Detailed description of the invention] This invention is a doll that is mainly used in watches, decorative display devices, etc., and is made to express natural movements using a novel drive mechanism that uses magnetic force. This invention relates to a motion drive mechanism.

Conventionally, as a doll drive mechanism, a drive motor etc. is built directly into the doll, etc., and the doll itself is driven by linking it with an external power source.As a result, the doll itself is driven. The disadvantage was that the structure was complicated and expensive.

Furthermore, as a separate mechanism, there is a device that expresses the movement of a hanging doll, but it gives an unnatural feeling because the threads are exposed on the outside.

The present invention has been devised in view of these points, and its contents will be explained below based on the illustrated embodiments.

Regarding the first embodiment (FIGS. 1 to 8).

1 is the clock mechanism body, 2 is the glass hood,
3 is a case incorporating a power mechanism for rotationally driving a doll or the like. Reference numeral 5 denotes a rotatable rotating shaft projected from the center of the upper surface 4 of the case 3. An arm 6 made of wire or the like is mounted on the top 5A of the rotating shaft 5.
The distal end 6A of the arm 6 is bent into a substantially U shape. 7 is a hanger suspended from the tip 6A of the arm 6;
A donkey doll 8 is attached to the lower end of the figure.

9A, 9B, 9C, and 9D are the legs of the doll 8, and each leg is suspended from the body 8A by a string 10 or the like in a reference state. 11 is each of the legs 9A, 9B,
With the magnet fixed to the bottom of 9C and 9D, the lower side is the N pole,
The upper side is the S pole. Further, the distance between the legs 9A and 9B and the legs 9C and 9D in the reference state is defined as _l3 .

12 is a stopper attached to the body 8A of the doll 8, and legs 9A and 9B to which the magnet 11 is fixed, and the leg 9.
It has a function of preventing C and 9D from being unnecessarily touched by their magnetic action. Further, on the lower surface 4A of the case 3, a plurality of magnets 13... are arranged around the circumference at an appropriate distance _l1 , and clock mechanisms 13A,... are arranged concentrically inside the magnets 13... They are placed around the circumference at an appropriate distance _l2 . The relationship between the distances l ₁ and l ₂ is as follows.

l ₃ <l ₁ and l ₃ <l ₂ These relationships satisfy one condition for causing the doll 8 to move its legs alternately.

Further, the magnet 13A is shifted by an angle of deviation α with respect to the reference diameter line N between the rotating shaft 5 and the magnet 13 located on the outermost circumference. This is a condition for causing the doll 8 to move its legs alternately.

Thus, by satisfying both of the conditions l ₃ <l ₁ and l ₃ <l ₂ argument α, the legs of the doll 8 can be alternately and smoothly moved.

The polarities of the magnets 13 and 13A are such that the upper side is the S pole and the lower side is the N pole, as shown in FIGS. 4 to 8. Also, in this way, the magnets 13, 13A and the magnets 11 attached to the legs 9A, 9B, 9C, 9D of the doll 8 are made to face each other, and the legs 9 are moved by using the attractive force of the magnets.
A, 9B, 9C, and 9D can be moved smoothly.

Next, the operation of the present invention constructed as described above will be explained.

In FIGS. 5 to 8, the present embodiment represents the motion of a donkey doll 8, which is a four-legged animal. When the rotating shaft 5 is rotated by a power mechanism (not shown) for rotationally driving the doll, the arm 6 is also rotated in the same direction, that is, in the direction of arrow A, and accordingly, the doll is suspended from the hanger 7. The doll 8 rotates around the rotating shaft 5, and the doll 8 is caused to pass over the upper surface 4 of the case 3 through the magnetic field created by the magnets 13, 13A. This doll 8
As each leg 9A, 9B, 9 rotates in the magnetic field of
Due to the mutual attraction between the magnets 11 of C and 9D and the magnets 13 and 13A disposed in the case 3, the leg 9
A, 9B, 9C, and 9D can be operated alternately. Thereafter, the same operating state is repeated.

Regarding the second embodiment (Fig. 9).

In this embodiment, the same parts as in the first embodiment are given the same numbers.

A feature of this embodiment is that a human-shaped doll 8 is used. In this case, right foot 15A and left foot 1
A magnet 11 is attached to each of the magnets 5B and 5B, and these magnets 13 and 13A face each other so as to be attracted to each other.

Next, as the doll 8 rotates, the right leg 15A moves backward due to the attractive force of the magnet. Further, due to the rotation of the doll 8, the right leg 15A is forcibly separated from the magnet 13A, and as a result of mutual attraction with other adjacent magnets 13A, the right leg 15A moves one step forward.

Similarly, the left leg 15B is repeatedly attracted to and detached from the magnet 13 as the doll 8 rotates.

Therefore, walking motion can be expressed on the doll 8. Although the magnets 13 and 13A are arranged in two rows in this embodiment, for example, in the case of a multi-legged octopus doll, they may be arranged in eight rows and arranged concentrically. Further, in the above embodiments, the case has been described in which the doll is made to move using the attractive force of the magnet, but it goes without saying that the repulsive force of the magnet may also be used.

Therefore, the present invention has the structure and operation as shown in the first and second embodiments, and in particular, the legs of various dolls are made to move alternately through the interaction of magnetic forces, so that the external appearance is improved. Since the upper drive mechanism is not visible, the movement itself looks natural and gives a mysterious impression to the viewer.Moreover, the movement can be freely varied by changing the arrangement of the magnets, and the doll itself is driven directly. Since there is no need to provide a power source, the doll can be made compact, and the structure can be simplified and provided at low cost.
