The doll is configured such that the head swings from side to side with respect to the trunk.
Japanese Patent Laying-Open No. 2005-193060 (see FIG. 1)

  The problem to be solved by the present invention is that the above-mentioned swing toy is composed of two dolls, an adult doll and a child doll, but swings the head of an adult doll which is one swing body. However, the child's doll does not move, and does not swing a plurality of swinging bodies at the same time.

  An object of the present invention is to solve the above-mentioned problems and to provide a swinging toy that can swing a plurality of swinging bodies in conjunction with each other with a simple structure.

In order to solve the above-mentioned problems, the swing toy according to the present invention is characterized by having the following requirements.

And (b) a connecting shaft is provided at each of the lower ends of the swinging members, and the connecting shafts of adjacent swinging members are connected to each other. (C) A magnet is disposed on the bottom surface of the coupling member, and a coil is disposed below the magnet in the base, and the coil is Generate magnetic force periodically in a control circuit powered by a solar cell installed on the base

Moreover, the swing toy according to the present invention may have the following requirements.
(A) The swinging toy includes a base and a plurality of swinging bodies swinging on the base. Each of the swinging members that support the swinging body is provided with a support shaft. (B) A magnet is provided at each lower end of the swing member, and a coil is disposed below the magnet of one swing member. A magnetic circuit is periodically generated by a control circuit using a solar cell as a power source provided on the base. (C) The lower end of the one swing member is provided with an arm perpendicular to the swing direction, that the tip of the arm is provided with a magnet (d) a magnet provided on the other of the swing member other than the one of the oscillating member, that are arranged to suction or repelling the magnet of the arm

  According to the first aspect of the present invention, the oscillating bodies are connected to each other by the connecting member, and the magnet is provided on the connecting member. Therefore, the other oscillating body is not operated using the movement of one of the oscillating bodies. A plurality of oscillators can be swung with the small energy of the solar cell.

  According to the invention of claim 2, the other oscillating body is moved in conjunction with the movement of the main oscillating body, but the movement is not moved mechanically using a link or the like. A plurality of oscillators can be swung with the small energy of the solar cell.

  FIG. 1 shows an example of a swinging toy A according to the present invention. The swinging toy A is configured such that a swinging body 2 disposed on a base 1 swings left and right using a solar cell 3 as a power source. .

  The oscillating body 2 is formed to resemble the head of a monkey, and is supported by a monkey body 4 formed to protrude from the upper surface of the base 1 so as to be able to oscillate. The head 2 of the monkey which is a rocking body is attached to a rocking member 5 which will be described later, and as shown in FIGS. The support shaft 6 is supported by a bearing hole 7 formed of a round hole formed inside the body portion 4 (see FIG. 4). The support shaft 6 is formed in an inverted triangular cross section, and the vertex 6a, which is the lowest point, is in point contact with the inner peripheral surface of the bearing hole 7 to support the swinging member 5 with a point. The resistance is made as small as possible.

  A thin rod-like shaft portion 5a is continuously provided at the lower portion of the swing member 5, and a connecting shaft 8 is formed at the lower portion of the shaft portion 5a so as to protrude forward and backward. The connecting shaft 8 has a triangular cross section, and supports the connecting member 10 with a point so that an apex 8a which is the uppermost point is in point contact with an inner peripheral surface of a bearing hole 11 of the connecting member 10 described later. The resistance when moving is made small.

  The connecting member 10 includes a front member 12 and a rear member 13, and circular bearing holes 11 larger than the connecting shaft 8 are formed on the left and right sides.

  The front member 12 is formed with a long hole 16 for holding one end 15a of a metal support plate 15 having magnetism such as iron that supports the magnet 14, and the rear member 13 is also the other end of the support plate 15. A long hole (not shown) for holding 15b is formed, and an accommodating portion 17 for accommodating the magnet 14 together with the support plate 15 in a state where the magnet 14 is magnetized is formed.

  The two magnets 14a and 14b magnetically attached to the support plate 15 are magnetically attached to the support plate 15 with different magnetic pole faces.

  The coil 20 is generated by generating a magnetic force periodically by a control circuit 22 which is arranged directly below the connecting member 10 so that the swinging member 5 faces the magnet 14 in a stationary state, and operates with the solar cell 3 as a power source. The magnetic force is attracted to one of the two magnets 14a and 14b, and repels the other. In the present invention, the control circuit 22 is constituted by a blocking oscillation circuit that oscillates using the coil 20 as an oscillation coil, and the control circuit 22 is mounted on the circuit board 21 together with the coil 20.

  FIG. 5 shows a basic circuit diagram for explaining the control circuit 22 of the rocking toy. The control circuit 22 is composed of a charging circuit unit 24 including the solar cell 3 and an electrolytic capacitor 23, and an oscillation circuit including a blocking oscillation circuit. Part 25. The control circuit 22 starts charging the electrolytic capacitor 23 when light strikes the solar cell 3, operates the oscillation circuit 25 when the charging voltage reaches a constant voltage, and applies low frequency to the oscillation coil (hereinafter referred to as a coil) 20. Current flows. At this time, if a magnetic force is generated in the coil 20 and the switch 26 is turned on, a low frequency voltage is supplied from the coil 20 to the piezoelectric buzzer 27, and the buzzer corresponding to the frequency is driven by driving the piezoelectric buzzer at the frequency of the low frequency voltage. Sound is generated.

  When the oscillation circuit unit 25 operates and the electrolytic capacitor 23 is discharged and the voltage drops, the operation of the oscillation circuit unit 25 stops, the electrolytic capacitor 23 is charged again, and when charging is performed, the oscillation circuit unit 25 operates again. Therefore, as long as light continues to strike the solar cell 3, the entire circuit repeats charging of the electrolytic capacitor 23, starting operation of the oscillation circuit unit 25, discharging of the electrolytic capacitor 23, and stopping operation of the oscillation circuit unit 25. At this time, when the connecting member 10 is oscillating, the magnet 14 generates an electromotive force in the coil 20, and this electromotive force serves as a trigger for operating the oscillation circuit unit 25. The timing gradually matches the swinging cycle of the connecting member 10, and the swinging operation of the connecting member 10 continues as long as the solar cell 3 is exposed to light.

  According to the swinging toy having the above-described configuration, when light strikes the solar cell 3 and electricity is induced, the oscillation circuit unit 25 is activated and a current flows through the coil 20 to generate a magnetic force.

  When the magnetic force is generated in the coil 20, the magnet 14 a attached below the connecting member 10 is arranged so as to be attracted by the magnetic force generated by the coil 20, the connecting member 10 moves to the right in the drawing, The head 2 swings to the left (see FIG. 4A). When the electrolytic capacitor 23 is discharged, no current flows through the coil 20 and no magnetic force is generated, so that the connecting member 10 moves back to its original position. The magnet 14b attached to is repelled by the magnetic force generated by the coil 20 and moves to the left in the drawing, and the head 2 swings to the right (see FIG. 4B). In this way, when the coil 20 generates magnetic force, the magnet 14a is attracted and the connecting member rotates counterclockwise around the support shaft in FIG. 1, and when the magnetic force of the coil 20 is lost, the connecting member becomes its own weight. When the oscillation circuit is activated again and the coil 20 generates magnetic force, the magnet 14 repels the magnet 14b and further rotates clockwise, but the magnet 14 of the connecting member 10 generates an electromotive force on the coil 20. The generated electromotive force serves as a trigger for operating the oscillation circuit unit 25, and the repetitive operation of the entire circuit is gradually timed to the oscillation cycle of the connecting member 10, resulting in the oscillation member. 5 (oscillating body 2) continues to swing left and right.

FIG. 6 shows another example of a swinging toy. This swinging toy A1 can swing a plurality of swinging toys without using a connecting member.
In this swing toy A1, one parent frog 30 and two small child frogs 31 and 32 are arranged on the base 1, and when the head 30a of the parent frog 30 swings left and right, The lower jaws 31a and 32a of the child frogs 31 and 32 swing up and down.

  As shown in FIG. 7, the swinging toy A <b> 1 has a housing portion 36 for the magnet 14 formed at the lower end of the shaft portion 35 a of the swinging member 35. Two arms 37 and 38 are formed so as to protrude in a direction perpendicular to the swinging direction, and magnets 39 and 40 are attached to the ends of the arms 37 and 38.

  The lower jaws 31a and 32a of the child frogs 31 and 32 are attached to the body portions of the child frogs 31 and 32 by shafts 41 and 42 so as to be swingable up and down. The lower jaws 31a and 32a have magnets 43 and 44 fixed to the back of the rear part, and the front parts of the lower jaws 31a and 32a are formed longer than the rear parts of the shafts 41 and 42 and are heavy. When the front part rotates downward and the mouth is open, the swinging member 35 swings, and the magnet 39 at the tip of the arm 37 is positioned below the lower jaw 31a, the magnet 39 The magnet 43 attracts each other, and the lower jaw 31a is pivoted forward about the shaft 41 so that the mouth is closed.

  At this time, the magnet 40 at the tip of the arm 38 is separated from the lower side of the lower jaw 32 a, the magnetic force of the magnet 40 does not reach the magnet 44, and the lower jaw 32 a rotates downward about the shaft 42, Mouth open.

  According to the swing toy having the above-described configuration, when light strikes the solar cell 3 and electricity is induced, when the oscillation circuit unit 25 operates and a current flows through the coil 20 to generate a magnetic force, the magnet 14a is applied to the coil 20. When sucked and the head of the parent frog 30 swings to the left, the magnet 40 fixed to the tip of the arm 38 comes to be positioned below the lower jaw magnet 44 of the right child frog 32, so the arm magnet 40. And the lower jaw magnet 44 are attracted to each other, the lower jaw 32a is pivoted forward, and the right child frog 32 is closed. On the other hand, the left child frog 31 is in a state where the magnet 39 of the arm 37 is separated from the magnet 43 of the lower jaw 31a, so that the front portion of the lower jaw 31a rotates downward, and the left child frog 31 opens its mouth. It becomes a state.

  When the oscillation circuit 25 stops, the current flowing through the coil 20 stops and when the magnetic force disappears, the oscillator moves back to its original position. When the oscillation circuit 25 operates again and a current flows through the coil 20 to generate magnetic force, the magnet 14b. Repels the coil 20 and the head sways to the right. When the head 39 swings to the right and the magnet 39 fixed to the tip of the arm 37 is positioned below the magnet 43 of the lower jaw 31a of the left child frog 31, the magnet 39 of the arm 37 and the magnet 43 of the lower jaw 31a are At the same time, the front part of the lower jaw 31a pivots upward, and the left child frog 31 is closed. On the other hand, the right child frog 32 is in a state in which the magnet 40 of the arm 38 is separated from the magnet 44 of the lower jaw 32a, so that the front portion of the lower jaw 32a rotates downward, and the right child frog 32 opens its mouth. It becomes a state.

  When the coil 20 generates magnetic force and the head of the parent frog 30 swings, the mouth of the small frog on the side where the head of the parent frog 30 swings is closed, the mouth of the other small frog is opened, and the parent frog 30 opens. Since the child frog opens and closes in conjunction with the swinging of the head of the head, a swinging toy that is pleasant to the eye can be realized by moving the plurality of swinging bodies repeatedly.

  FIG. 8 shows still another example of the swinging toy. When the head 51 of the parent horse 50 swings, the swinging toy A2 swings the heads 54 and 55 of the foals 52 and 53. It is a thing.

  In this swing toy A2, one parent horse 50 and two foals 52, 53 are arranged on the base 1, and when the head 51 of the parent horse 50 swings left and right, the left and right foals The heads 54 and 55 of 52 and 53 are swung to the left and right in conjunction with each other. As shown in FIG. 9, the swinging toy A <b> 2 has a housing portion 57 for the magnet 14 formed at the lower end of the shaft portion 56 a of the swinging member 56. The arm 58 is formed so as to protrude in a direction perpendicular to the arm 58, and a magnet 59 is attached to the tip of the arm 58.

  The head of the foal is formed with projecting shafts 62 and 63 projecting from the front and rear of the swinging members 60 and 61, supported by a bearing hole (not shown) formed in the body portion, and extended downward. Magnets 64 and 65 are fixed to the lower ends of the shaft bodies 60a and 61a. The magnets 64 and 65 are attached so as to repel each other with the magnet 59 attached to the tip of the arm 58. When the head 51 swings in one direction (for example, the right direction), the magnet 59 of the arm 58 is changed to the head 51. The head 54 of the foal 52 repels the magnet 64 of the foal 52 so as to repel the magnet 64 of the foal 52. Rocks.

  When the head of the parent horse 50 swings in the opposite direction (leftward), the head 55 of the foal 53 swings in the same direction as the head 51 of the parent horse 50, and Since the heads 54 and 55 of the foals 52 and 53 swing in the same direction in accordance with the swing, the parent and child horses are aligned and the heads are swinged in the same direction, and a plurality of swinging bodies are aligned and swinged. This makes it possible to create a rocking toy that looks fun.

  The above-described rocking toys A to A2 include the piezoelectric buzzer 27 as shown in the circuit diagram of FIG. 5, so that when the switch 26 is turned on, a low frequency current flows through the coil 20. Since a low frequency voltage is generated at both ends of the coil 20 and this low frequency voltage drives the piezoelectric buzzer 27, the low frequency voltage is periodically supplied to the piezoelectric buzzer 27 and the buzzer sounds. The buzzer sound is output in synchronization with the swing of the swinging toy without the need to provide a sound as if a frog or foal is ringing, without the need for special circuitry or software. A swinging toy different from a conventional swinging toy in which the swinging body simply swings can be realized.
