Swing toys

Technical field

The present invention relates to a swinging toy, and more particularly, to a toy that has a size suitable for being placed on a desk or furniture, and allows a user to appreciate the state in which the swinging member swings smoothly.

Background art

There is known a mechanism that includes a permanent magnet and a coil, and swings the swing member using a magnetic force acting between the coil and the permanent magnet. There are the following conventional examples of peristaltic toys equipped with this type of mechanism.

Japanese Patent Application Laid-Open No. 2 0 5-5 8 4 1 7 describes an action toy provided with a peristaltic body provided with a magnet and a coil facing the magnet at the lower end of the holding body of the flower model body. When the coil is energized, the holding body rotates counterclockwise around the support shaft, and when the coil is no longer energized, it rotates back clockwise, and the moving body continues with the coil excitation. Swing left and right.

Japanese Patent Laid-Open No. 2 0 0 5-2 2 4 6 3 8 describes a swinging toy that includes a doll body on a base, and the head of the doll body swings left and right with respect to the torso. ing.振り A pendulum is installed inside the moving toy. This pendulum can swing left and right around the shaft supported by the body. The pendulum is fixed to the head at the upper part, while a permanent magnet is attached to the lower part.

An electromagnetic coil is installed inside the swinging toy. When the swinging toy is placed in a bright place, the solar battery is stored, and the stored power generates a voltage pulse from the watch and the electromagnetic coil is excited.

In this case, the electromagnetic coil switches polarity, and the pendulum swings left and right by the electromagnetic force. The part of the electromagnetic coil that faces the permanent magnet is the N pole. The pendulum moves to the left and right by switching the polarity.

Furthermore, Japanese Patent Application Laid-Open No. 2 0 5-1 5 2 5 1 4 has a flower pot model part, a soil model part, and a leaf model part, and the leaf model part swings upward and downward as a rocking body. A swinging toy is described that performs a dynamic motion (flapping motion) for a while.

A magnet is attached to the lower end of each swing member. The magnet is arranged so that the magnetic force from the electromagnetic coil placed below it acts. Each swing member is moved downward by a repulsive force acting between the magnet coil and the magnet by exciting the electromagnetic coil and a repulsive force acting between the magnets of the two swing members. In the non-excited state, each rocking member moves upward due to the gravity acting on each rocking member. If the repulsive force acting between the electromagnetic coil and the magnet is generated periodically, the oscillating member repeats the oscillating operation.

In the moving toy described in Japanese Patent Laid-Open No. 2 0 5-5 8 4 1 7, when the coil is excited, the holder rotates counterclockwise around the support shaft, and is held when the coil is no longer excited. Since the weight of the lower end of the body is applied to the holding body as it is and the holding body returns and rotates in a clockwise direction around the support shaft, the swing cannot be reproduced smoothly. Further, the swinging toy described in Japanese Patent Laid-Open No. 2 0 0 5-2 2 4 6 3 8 switches the polarity of the electromagnetic coil and swings the pendulum left and right by the electromagnetic force. The movement cannot be reproduced smoothly.

Unlike the former two toys, the swinging toy described in Japanese Patent Laid-Open No. 2 0 0 5-1 5 2 5 1 4 has a configuration that swings a pair of swinging members. Since it has a magnet and an electromagnetic coil, the number of parts increases and the structure becomes complicated.

Furthermore, when each electromagnetic coil is excited, the oscillating member rotates downward about the axis, and then when the electromagnetic coil is de-energized, the gravity at the lower end of each oscillating member is reduced. Since the rocking member is directly added to the rocking member, and the rocking member returns to the upper part at once with the shaft as the center, the speed of the rocking body in the rocking process is not uniform and the rocking is reproduced smoothly. I can't. Disclosure of the invention

Next, an embodiment of a swinging toy according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the entire swinging toy. This rocking toy includes a housing 10 and an insect-like model body 12 placed on the housing 10.

The model body 12 resembles a butterfly, and includes a trunk portion 14 and a pair of left and right wing members 16 A and 16 B of the trunk portion 14. The pair of wing members 16 A and 16 B corresponds to a pair of swing members for reproducing natural flapping of butterfly wings.

In the casing 10, a pair of wing members 16A, 16B is used to rotate back and forth symmetrically left and right symmetrically as shown by the alternate long and short dash line around the barrel 14. A shaking device (40 in Fig. 2) is provided. Details of the swing device will be described later. The Note that the accessory case 20 as shown in FIG. 2 can be attached to and detached from the surplus space 22 in the housing i 0.

As shown in FIG. 3, the housing 10 is composed of a lid body 24 and a main body 26. As shown in FIG. 4, a rectangular opening 28 is formed at the substantially center of the upper surface of the main body 26. A block having a pair of bearings 3OA and 30B is formed in this opening. 3 2 is placed.

Both ends of the block 3 2 are fixed to the flat surface 26 A of the main body 26 by screws 3 4. A lower end 3 2 A of the block 3 2 extends at a right angle from the opening 28 toward the bottom surface of the main body 26, and further includes a space 3 2 C for accommodating a rocking body described later.

Further, the block 3 2 is provided with a recess 3 2 B in which the block is cut out in the length direction of the body portion 14, and a hook-like member 10 2 (FIG. 12) described later is provided in the recess 3 2. B can be moved forward and backward in the length direction of the body 14. Details will be described later.

As shown in FIG. 3, an oscillating device 40 is accommodated in the main body through the opening 28 of the main body 26. A pair of shaft members of the rocking device 4 2 is a block 3 2 A pair of bearings 3

It is placed on each of O A and 30 B (see FIG. 4).

As a result, the swing device 40 rotates about a shaft member 42 along a virtual plane defined in a direction perpendicular to the plane of the main body 26. The part below the shaft member 4 2 of the oscillating device is disposed inside the main body 26 from the opening 28, and at least a part of the upper part from the shaft member 42 becomes the projecting part 44. It extends from 2 6 to the lid 2 4.

The protrusions 44 are paired at the end of the swing device on the lid 24 side. The lid body 24 is provided with a pair of rectangular small openings 46 so that the pair of protrusions 44 are exposed to the body 14 side. A claw body 48 is attached to each protruding piece exposed from the small opening 46, and the wing member 1 6 A, 1 is attached to the claw body 48. 6 B base is fixed.

Leg pieces 50 are provided at the four corners of the back surface of the main body 26 side of the substantially square lid body 24, respectively. On the other hand, round holes 52 are formed in the four corners on the lid side of the main body. The leg pieces 50 are inserted into the corresponding round holes 52 and the lid body 24 is screwed to the main body 26 to fix the both.

A rectangular solar cell 54 is provided on the surface of the main body 26. The lid 2 4 has a rectangular opening 5 6 for exposing the panel. Reference numeral 58 denotes a circular electromagnetic coil fixed inside the main body. A solar cell may be provided on the side surface of the main body 26.

Next, the details of the swing device will be described. FIG. 5 is a perspective view showing the entire swinging device 40, FIG. 6 is a perspective view showing the component configuration of the swinging device, and FIG. 7 is an exploded perspective view showing the assembled state of the entire swinging device. FIG.

The swing device is mainly composed of the first swing arm 60 and the second swing arm 6.

It consists of two. Each swing arm is substantially L-shaped, and is combined in a direction perpendicular to the length direction of the body 14 so that the two swing arms intersect each other. The first swing arm 60 is on the caudal side of the moon 14 with respect to the second swing arm 62.

This can be easily understood by referring to FIG.

The tip, which is the base end side where the protruding portion 44 of the swing arm described above is located, is inflated in a circular shape, and button-shaped weights 60 A and 60 B are respectively provided in the swollen portion. It is fixed.

In addition, a cylindrical boss portion 64 is formed on the leading end side of each swing arm in a direction orthogonal to the swing arm, that is, along the length direction of the trunk portion 14, and the center of this boss portion is formed. The above-described shaft member 42 penetrates along the length direction of the body portion 14, and the shaft member 42 is slightly exposed at each of both end sides of the boss portion 64. The exposed portion of the shaft member 4 2 is rotated on the bearings 30 A and 30 B described above. It will be supported by the present.

The first swing arm 60 and the second swing arm 62 are in the direction of each other along a virtual plane that intersects with the surface on which the opening portion 28 of the main body 26 is formed around the shaft member. To turn.

From the lower position in the vicinity of the boss portion 64 of the first swing arm 60, the branch arm 66 extends shortly toward the side opposite to the direction in which the weight 6OA on the front end side exists. The tip of the branch arm swells in a circular shape, and a button-like permanent magnet 68 is fixed to the swelled portion.

The rocking device further includes a small S-shaped part 6 8 A. At both ends of the small part, there are small-diameter short shafts 70 and 72A (7OA is shown in FIG. 6) extending toward the tail along the length direction of the body 14. The short axis of the first swing arm 60 on the permanent magnet 68 side is fitted into the small diameter hole 74 of the first swing arm, whereby the small part 68 is fixed to the first swing arm 60.

-On the other hand, the shaft 70 on the 60 A side of the first swing arm of the small part is exposed inside the L-shape of the first swing arm without intersecting the first swing arm. This can be easily understood with reference to FIG.

A small flange 71 extends from the base end side of the second swing arm 62 in the direction in which the weight 60B is located, and a substantially elliptical groove 72 is formed in the small flange 71.

The swing device is completed by combining the first swing arm 60 and the second swing arm 62. The assembly is performed as follows. First, the small part 68 is fixed to the first swing arm 60 as described above.

Next, as shown in FIG. 7, the first swing arm 6 ◦ and the second swing arm 62 are crossed so that the first swing arm 60 is on the tail side of the trunk 14, and At this time, the short shaft 70 of the small part 6 8 is inserted into the elliptical groove 7 2 of the small flange 71 of the second swing arm. Combination of elliptic groove 7 2 and minor axis 70 This forms one form of transmission means for transmitting the rotational driving force of the first swing arm 60 to the second swing arm 62.

As a result, as shown in FIG. 5, a swinging device composed of a combination of the first swing arm 60 and the second swing arm 62 is obtained. In this oscillating device, the shaft member 42 of the first swing arm 60 and the shaft member 42 of the second swing arm 62 are juxtaposed in parallel with each other, as shown in FIG. The pair of shaft members 42 are parallel to each other and are juxtaposed on the bearings 30 A and 30 B.

The above-described protruding piece 44 is exposed upward from the shaft member 42, and the claw body 48 is engaged with this exposed portion. The first swing arm 60 can be rotated about its own shaft member 42, and the second swing arm 62 can similarly be rotated about its own shaft member 42.

As described above, the first swing arm 60 and the second swing arm 6 2 are the small parts 68 fixed to the first swing arm 60 and the short axis 70 is the second swing. The arm 62 is connected by connecting means formed by fitting into an elliptical groove 7 2 of the small flange 71 of the arm 62.

Therefore, the driving force applied to the first swing arm 6 ◦ to rotate the swing arm is transmitted to the other swing arm 62 through the connection structure. As a result, the first swing arm 60 and the second swing arm 62 are opposite in rotation direction, but are symmetrical and rotate along the imaginary plane as described above at the same cycle.

Also, due to the coupling structure, the magnet 6 8 of the first swing arm 60 and the weight 60 A and the weight 6 2 B of the second swing arm 6 2 influence each other, and the first swing arm When the shaft members 4 2 of the second swing arm and the second swing arm are placed on the bearings 30 A and 30 B, the weight balance between the first swing arm and the second swing arm is balanced. It becomes a state. Therefore, if a driving force that breaks this balance is applied to one swing arm of the swinging device, the two swing arms can be rotated while operating even if this driving force is not large.

The aforementioned driving force applied to the swing device is obtained by the magnetic field generated by the coil 58 with respect to the permanent magnet 68 at the tip of the branch arm 66 of the first swing arm 60. (See Figure 5).

The magnet 68 is fixed to the tip of the branch arm 66 so that the direction perpendicular to the shaft member 42 is the radial direction. The circular magnet is located slightly away from the tail of the body 14 and can interact magnetically with the permanent magnet, and the branch arm 66 is in the first swing. The circular coil 5 8 described above is attached to the support shaft 4 2 of the first swing arm 60 so that the movement of the permanent magnet is not obstructed when it is rotated around the shaft member 4 2 of the arm 60. It is fixed to the main body 26 with the orthogonal direction as the radial direction.

As shown in Fig. 5, the magnet 6 8 and the coil 5 8 have their planes facing each other in parallel, and the two swing arms of the oscillating device are in a neutral state in which the weight is balanced. When the coil and magnet are viewed in the length direction of the body, the center 6 8 T of the magnet 6 8 is the center of the coin 5 8 as shown in the schematic diagram of FIG. A fixed position with respect to the main body of the magnet 68 and a neutral position are set so as to be positioned above T. Magnet 6 8 center 6 8 T force Magnet 4 8 center of rotation 6 8 center 5 8 T trajectory 1 60 Position so that it is on the core 5 8 and magnet 6 8 Is set.

When the magnet 68 and the coil 58 are in such a relationship, the control circuit as a switch means described later excites the coil 58 from the neutral position taken by a pair of swing arms. Acting on the permanent magnet 68, the permanent magnet 68 tries to move to a position where it overlaps the coil 58 as shown in FIG. At this time, the first swing arm 60 is centered on the shaft member 42 and the second swing arm 60 is When the first swing arm 6 0 is viewed from the side where the swing arm 6 2 is located, the first swing arm 6 2 rotates counterclockwise, and the second swing arm 6 2 is pivoted on its axis via the connecting means described above. Rotate clockwise around member 4 2.

In a state where the weight balance between the first swing arm 60 and the second swing arm 62 is balanced and both are in a neutral position, that is, when the coil 58 is not excited, the base ends of these swing arms The pair of wing members 16 A, 16 B fixed to the part takes a position where the butterfly closes the wing. On the other hand, when the coil 58 is in an excited state, a pair of protrusions (44, 4 in FIG. 3) are separated from each other by a protrusion at the tip of the first swing arm and a protrusion at the tip of the second swing arm. The butterfly opens its wings according to the positional relationship (biasing position). Incidentally, Figure 1 shows the butterfly wings open.

Since the swing of the wing member is reproduced using the above-described weight balance in the swing device, the magnetic field intensity generated from the coil 58 is not required to be so strong. Therefore, the swing can be reproduced smoothly.

Further, since the pair of swing arms are connected to each other by the connecting structure, a driving force for swinging may be applied to one swing arm side. In the above-described embodiment, the coil is provided only for the first swing arm 60. Since it is possible to omit providing a coil for the second swing arm, it is possible to simplify the structure of the drive mechanism that drives the swing device by omitting the number of parts.

Here, the drive mechanism is composed of the solar cell 54 described above, the circular coil 58, and a control circuit to be described later as switch means for controlling excitation of the circular coil. The control circuit intermittently supplies current to the coil 58. The electromagnetic coil periodically generates and cancels the magnetic field. The first swing arm and the second swing arm of the swinging device reciprocate between a neutral position in which the weight balance between them is balanced and an urging position displaced by a magnetic field. the latter Since the weight balance described above is used for the return from the position to the former position, the wing member swings more smoothly.

Fig. 9 (1) shows that the weight balance between the first swing arm and the second swing arm of the swinging device is balanced and both are in the neutral position, and (2) is the state of the first swing arm. The magnetic field from the electromagnetic coil 58 is applied to the permanent magnet 68, and both are in the biased position.

In the process in which the swinging device reciprocates between the neutral position and the biasing position, the small part 6 8 of the first swing arm 60 is the groove of the small flange 7 1 of the second swing arm 62. The groove 72 of the small flange has a track shape wider than the short axis 70 so that it can move within 72.

Next, means for stopping the swinging of the swinging body by the swinging device will be described. FIG. 10 is a perspective view of the bottom surface of the main body 26 viewed obliquely, and the plane including the bearings 3 O A and 3 OB described above, the oscillating device 40 and the drive mechanism are not shown.

Reference numeral 1 0 0 is a stop as a stopping means. Fig. 12 is a perspective view of the stop as viewed from the plane of the main body, and Fig. 13 is a perspective view of the stop as viewed from the back. As can be seen from these figures, the stopper has a thin, substantially hook-shaped piece 10 2 protruding at right angles from the center line of the rectangular plate 1 0 1. A stopper is arranged on the bottom surface 26 B side of the main body so that the protruding piece 10 2 faces the upper surface side of the main body.

There are track-like grooves 10 4 at both ends of the plate 100 1, and small cylinders 10 6 protruding perpendicularly from the inside of the bottom surface of the base are fitted in the grooves. As a result, the stagger can advance and retreat in the length direction of the body portion 14 while being restricted by the length of the groove 104. The rectangular plate 1 0 1 has a rectangular parallelepiped small protrusion 1 0 6 along its longitudinal direction on the back surface, and this small protrusion 1 0 6 is exposed to the outside of the base from the rectangular hole 1 0 8 in the base bottom. ing. The user operates this small protrusion 1 0 6 The stopper can be advanced and retracted as described above.

The hook-shaped projecting piece 1 0 2 has a taper surface 1 1 0, and the stopper 1 0 0 is attached to the main body 2 6 so that the taper surface 1 1 0 comes to the aforementioned swinging device side. It is placed inside the bottom. As shown in FIG. 11 to FIG. 10, when the stopper 10 0 0 is moved to the swing device 40 side, this tapered surface 1 1 0 is formed on the swing device as shown in FIG. Even if the electromagnetic coil 58 is excited by coming into contact with the lower end of the first or second swing arm, the swing of the swing arm is interfered.

As a result, the swing of the wing members 16 A and 16 B is suppressed. On the other hand, as shown in FIG. 10 to FIG. 11, when the stopper 100 is separated from the swinging device 40, the taper surface 110 and the swing arm are not interfered with each other. Is allowed to rotate, and as a result, the swinging of the wing member is resumed. In this embodiment, the taper surface is in contact with the lower end of the second swing arm 62 to prevent the swinging member from swinging.

Next, a control circuit for intermittently exciting the electromagnetic coil 58 as a switch means will be described. FIG. 15 is a block diagram of the control circuit. This control circuit intermittently supplies the current generated in the solar cell 5 4 (BT 1 in FIG. 15) to the electromagnetic coil 58 (L 1 in FIG. 15). Since the weight balance of the oscillating device is used to return from the biased position to the neutral position, it is not necessary to change the polarity of the current supplied to the electromagnetic coil.

In Fig. 15, when a certain amount of charge is applied to the capacitor C 1 from the power supply BT 1, the potential of the capacitor C 1 rises, the transistor Q 1 is turned on, current flows to the electromagnetic coil (L 1), and the coil is The magnetized coil is energized and attracts the permanent magnet 68, so that the pair of swing arms takes the biased position described above. When the electric charge is discharged from the capacitor C1, the potential is lowered and the transistor Q1 is turned OFF, the current supply to the electromagnetic coil (L1) is stopped, and the permanent magnet 68 is released from the energized position, and a pair of swing arms Is the neutral position already described Will return to the default position. Thereafter, the electromagnetic coil intermittently and magnetically acts on the permanent magnet by repeated charging and discharging of the capacitor C1. As a result, the pair of arms can reciprocate between the neutral position and the biasing position, and the movement of the wing member opening and closing can be reproduced.
