Abstract

(57) [Abstract] [Purpose] The present invention relates to an improvement in the arm swing structure of a doll in which the arms provided in a conventional doll are swingable in the vertical direction, and there is a small number of parts, only one arm, both arms. It is an object of the present invention to provide a structure in which both arms can be operated simultaneously or alternately. According to the arm swing structure of the present invention, an action rod 24, 26, a motor 28, and a worm are formed in a doll case constituted by a front cover 14 and a rear cover 16 in a direction perpendicular to the rotation axes 44, 46 of the doll. L-shaped links 30 and 32 fixed to both ends of the rotation shaft of the wheel 34, the worm 36 fixed to the rotation shaft of the motor 28 is housed, and the L-shaped link and the action rod are engaged / disengaged as the motor rotates. repeat.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 This invention relates to a structure for swinging arms of a doll used for a mechanical clock or the like.

[0002]

[Prior Art]

 In recent years, as represented by Karakuri timepieces, there are various kinds of timepieces provided with ornaments such as dolls. In this type of timepiece, a doll's arm swing structure in which the doll's arm can be swingably driven in the vertical direction is, for example, as shown in FIG. It is known to drive and rotate.

More specifically, in the doll 2, a rotor magnet 8 for rotating an arm 6 having a hammer 4 and a coil winding for giving a repulsive force to the rotor magnet 8 are provided. A turned yoke 10 is provided. Then, the yoke 10 is excited by the doll driving current sent from the control circuit (not shown) only while the current is flowing, and if the excited yoke 10 and the rotor magnet 8 have the same magnetic poles, A repulsive force is generated and the rotor magnet 8 rotates, so that the arm 6 attached so as to rotate integrally with the rotor magnet 8 rotates and the hammer 4 is struck on the bell 12. When the drive current is cut off, the magnetic force of the yoke 10 disappears and the arm 6 returns to its original position by its own weight. By repeating the above pattern, the operation of the doll 2 hitting the stick 12 is repeated.

[0004]

[Problems to be solved by the device]

 Thus, in the case of a doll that drives only one arm 6 as shown in FIG. 3, one rotor magnet 8 and one yoke 10 are required. However, for example, in the case of a doll that moves its arms up and down with a maraca, or in the case of a doll in which drums are continuously hit with both hands, two pairs of rotor magnets 8 and yokes 10 for driving each arm are required. As a result, the number of drive parts and the number of components that make up the drive parts is increased, resulting in an increase in the number of assembly steps and a high cost.

[0005]

[Means for Solving the Problems]

 Therefore, in the present invention, the arm swing structure of the conventional doll, which is equipped with the arms that can be swingably driven in the vertical direction, has been improved. A working rod provided on the rotary shaft of the arm, a motor, a worm wheel pivotally supported by fixing L-shaped links at both ends of the rotary shaft, and a worm that meshes with the worm wheel on the rotary shaft of the motor. And the L-shaped link is repeatedly engaged and disengaged with the action rod provided on the doll's arm as the motor rotates, and the L-shaped link is provided on the doll's arm when engaged. The action rod was pressed to give an upward rotation, and when it was released, it was returned to its original position by the weight of the arm.

[0006]

[Action]

 According to the structure of the present invention, by simply rotating the motor in a certain direction, the L-shaped link driven by the motor presses the action rod provided on the arm of the doll to apply the rotational force to the arm. Rotate the arm upwards. When the link is released, the arm returns to its original position under its own weight. Such a structure can operate only one arm, both arms at the same time, or both arms can be operated alternately, and no special circuit is required.

[0007]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. The doll according to the present invention comprises a front cover 14, a rear cover 16, a hat 18, and both arms 20, 22 whose rotary shafts described later are pivotally supported by the front cover 14 and the rear cover 16. In the doll case composed of the front cover 14 and the rear cover 16, the action rods 24, 26, the motor 28, the L-shaped links 30, 32, the worm wheel 34, and the motor, which are the features of the present invention, are provided. A worm 36 fixed to the rotating shaft of 28 is accommodated therein, which will be described in detail below.

A plurality of bosses 38 are erected from the inner wall of the rear cover 16 of the doll, and the receiving plate 40 is fixed. First, a worm wheel 34 having a rotating shaft 29 is pivotally supported on the receiving plate 40. L-shaped links 30 and 32 are press-fitted and fixed to both ends of the rotary shaft 29 in advance. After that, the motor 28 having the worm 36 fixed to the rotary shaft is elastically coupled by the elastic arm 42 formed on the receiving plate 40. At this time, the worm wheel 34 and the worm 36 must be in mesh with each other.

Action bars 24, 26 are formed on the rotary shafts 44, 46 of the arms 20, 22 pivotally supported by the front cover 14 and the rear cover 16 in a direction perpendicular to the shafts. The action rod repeats engagement and disengagement with the rotation of the L-shaped links 30 and 32, and is arranged in front of the links 30 and 32. The arm 20 is configured such that its center of gravity is located forward (on the side of the front cover 14) with respect to the rotation axis, and when the L-shaped link with the action rod is released, the arm 20 returns to its original weight. Reference numeral 48 is a lead wire for passing an electric current to the motor 28, which is led to the outside of the doll case through a through hole appropriately provided.

In the above structure, when current is supplied, the rotation of the worm 36 of the motor 28 is transmitted to the worm wheel 34 and the L-shaped link rotates. The link repeatedly engages and disengages with the work rod, and when engaged, the link presses the action rod, so that the arm swings upward, and when released, the arm returns to its original position by its own weight. It will be.

[0011]

As described above, the motion mechanism of the doll of the present invention can move the arm of the doll up and down simply by rotating one motor in a certain direction. However, it can be applied to either arm or both arms, and it is versatile that both arms can be used simultaneously or alternately by simply changing the positions of links or working rods, and no special circuit is required. .. Therefore, it is possible to suppress the increase in the number of parts as much as possible, and thus it is possible to prevent the cost from increasing.
