Description

  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 smooth swinging of a swinging member.

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

  Japanese Patent Application Laid-Open No. 2005-58417 describes a moving toy including a swinging body having a magnet at a lower end of a flower model holding body and a coil facing the magnet. When the coil is excited, the holding body rotates counterclockwise about the support shaft, and when the coil is no longer excited, the holding body rotates clockwise and the oscillator continuously moves along with the coil excitation. Swings left and right.

  Japanese Patent Application Laid-Open No. 2005-224638 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. A pendulum is installed inside the swinging toy. The pendulum can swing left and right around an axis 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 charged, and a voltage pulse is output from the timepiece by the stored electric power, and the electromagnetic coil is excited.

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

  Furthermore, Japanese Patent Application Laid-Open No. 2005-152514 has a flower pot model part, a soil model part, and a leaf model part, and the leaf model part continues to swing up and down (flapping action) as a swinging body for a while. A swinging toy is described.

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 installed below it acts. And each rocking | fluctuation member operate | moves below by the repulsive force which acts between the electromagnetic coil and magnet by exciting an electromagnetic coil, and the repulsive force which acts between the magnets of two rocking members, In the non-excited state, each swing member moves upward due to the gravity acting on each swing member. If the repulsive force acting between the electromagnetic coil and the magnet is periodically generated, the swing member repeats the swing operation.

  In the moving toy described in Japanese Patent Application Laid-Open No. 2005-58417, when the coil is excited, the holding body rotates counterclockwise around the support shaft, and when the coil is no longer excited, the weight of the lower end of the holding body is held as it is. Since the holding body joins the body and rotates and returns in a clockwise direction around the support shaft, the swing cannot be reproduced smoothly.

  Furthermore, since the swing toy described in JP-A-2005-224638 switches the polarity of the electromagnetic coil and swings the pendulum left and right by the electromagnetic force, the swing cannot be reproduced smoothly.

  Unlike the former two toys, the swinging toy described in JP-A-2005-152514 has a configuration that swings a pair of swinging members, but each swinging member includes a magnet and an electromagnetic coil. As a result, the number of parts increases and the structure becomes complicated.

  Further, when each electromagnetic coil is excited, the swing member rotates downward about the axis, and then when the electromagnetic coil is de-energized, gravity at the lower end of each swing member is directly applied to the swing member. Since the swinging member returns to the upper part at once with the shaft as the center, the speed of the swinging body in the swinging process is not uniform and the swinging cannot be reproduced smoothly.

  Therefore, an object of the present invention is to provide a swing toy that can smoothly reproduce the swing of the swing member. Furthermore, an object of the present invention is to provide a swinging toy that has a configuration that swings a pair of swinging members, but that does not become complicated due to an increase in the number of parts.

  In order to achieve the above object, the present invention is a swing toy, wherein an opening is provided on an upper surface, a housing, a pair of shaft members juxtaposed in parallel with each other, and the shaft member. Are provided so as to be capable of rotating in symmetrical directions along a virtual plane intersecting the plane on which the opening of the casing is formed, and a portion located below the shaft member is provided on the casing. A pair of arm members disposed inside and positioned above the shaft member at least partially projecting from the housing and the pair of arm members are movably connected to each other, A connecting means arranged to transmit the rotational driving force supplied to the arm member to the other arm member; a weight attached to each lower end of the pair of arm members arranged in the housing; , That of the pair of arm members A swing arm attached to a portion projecting from the housing and a branch arm member that branches from at least one of the pair of arm members, and whose tip end portion rotates along the virtual plane And a permanent magnet attached to the tip of the branch arm member, and a position where the permanent magnet is magnetically interacting with the permanent magnet, and at a distance that does not hinder the movement of the permanent magnet. An electromagnetic coil arranged in parallel along the virtual plane, a current source for supplying a current for exciting the electromagnetic coil, and a switch means for intermittently controlling the flow of the current supplied to the electromagnetic coil. When the coil is not excited, the pair of arm members are in a neutral position in which the weight balance is balanced with each other. When the coil is excited from this state, the excited coil The pair of arm members are rotated in symmetrical directions along the virtual plane and displaced from the neutral position by the rotational driving force supplied to the tip portion by the magnetic force acting between the permanent magnets. When the excitation of the coil is released, the pair of arm members return from the biased position to the neutral position so that the weight balance can be achieved, and as a result, depending on the operation of the switch means As the electromagnetic coil intermittently and magnetically acts on the permanent magnet, the pair of arm members reciprocate between the neutral position and the biasing position, and the rocking body swings with this reciprocation. It is characterized by forming movement.

  According to the present invention, it is possible to provide a swing toy that can smoothly reproduce the swing of the swing member. Furthermore, according to the present invention, it is possible to provide a swinging toy that has a configuration that swings a pair of swinging members, but that does not become complicated due to an increase in the number of parts.

  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 16A and 16B. The pair of wing members 16A and 16B corresponds to a pair of swinging members for reproducing natural flapping of butterfly wings.

  In the casing 10, a pair of wing members 16A and 16B are pivoted in a reciprocating manner up and down symmetrically with respect to the body portion 14 as shown in FIG. 40). Details of the swing device will be described later. An accessory case 20 as shown in FIG. 2 can be attached to and detached from the surplus space 22 in the housing 10.

  As shown in FIG. 3, the housing 10 includes a lid body 24 and a main body 26. As shown in FIG. 4, a rectangular opening 28 is formed at substantially the center of the upper surface of the main body 26, and a block 32 having a pair of bearings 30 </ b> A and 30 </ b> B is placed in the opening. .

  Both ends of the block 32 are fixed to the flat surface 26 </ b> A of the main body 26 by screws 34. A lower end 32A of the block 32 extends perpendicularly from the opening 28 toward the bottom surface of the main body 26, and further includes a space 32C for accommodating a rocking body described later.

  Further, the block 32 is provided with a recess 32B in which the block is cut out in the length direction of the body portion 14, and a hook-like member 102 (FIG. 12), which will be described later, connects the recess 32B in the length direction of the body portion 14. You can advance and retreat. Details will be described later.

  As shown in FIG. 3, the swinging device 40 is accommodated in the main body from the opening 28 of the main body 26. A pair of shaft members 42 of the swing device are placed on each of the pair of bearings 30A and 30B of the block 32 (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. A portion below the shaft member 42 of the swinging device is disposed inside the main body 26 from the opening 28, and at least a part of the upper portion from the shaft member 42 becomes a projecting portion 44 toward the lid 24 from the main body 26. It extends.

  The protrusions 44 exist as a pair 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 protruding portions 44 are exposed to the body portion 14 side. A claw body 48 is attached to each protruding piece exposed from the small opening 46, and the base ends of the wing members 16 </ b> A and 16 </ b> B are fixed to the claw body 48.

  Leg pieces 50 are provided at the four corners of the back surface of the substantially square lid 24 on the main body 26 side. On the other hand, round holes 52 are formed in the four corners on the lid side of the main body. By inserting the leg pieces 50 into the corresponding round holes 52 and screwing the lid body 24 onto the main body 26, both are fixed.

  A rectangular solar cell 54 is provided on the surface of the main body 26. The lid 24 has a rectangular opening 56 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, 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 a component configuration of the swinging device, and FIG. 7 is an exploded perspective view showing an assembled state of the entire swinging device. is there.

  The swing device is mainly composed of a first swing arm 60 and a second swing arm 62. Each swing arm is substantially L-shaped, and is combined in a direction perpendicular to the length direction of the body portion 14 so that the two swing arms intersect each other. The first swing arm 60 is closer to the tail side of the body portion 14 than the second swing arm 62. This can be easily understood with reference to FIG.

  The tip of each swing arm, which is the other end side with respect to the base end side where the projecting portion 44 is located, bulges in a circular shape, and button-like weights 60A and 60B are fixed to the bulge portion, respectively.

  Further, a cylindrical boss portion 64 is formed on the front 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 the boss portion is described above. The shaft member 42 penetrates along the length direction of the body portion 14, and the shaft member 42 is slightly exposed at both end sides of the boss portion 64. The exposed portion of the shaft member 42 is rotatably supported by the bearings 30A and 30B described above.

  The first swing arm 60 and the second swing arm 62 rotate in the target direction with respect to each other along a virtual plane that intersects the plane on which the opening 28 of the main body 26 is formed with the shaft member as a center. .

  A branch arm 66 extends from the lower position in the vicinity of the boss portion 64 of the first swing arm 60 toward the side opposite to the direction in which the weight 60A on the tip side is present. 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 oscillating device further includes a substantially S-shaped small part 68A. At both ends of the small part, there are small-diameter short axes 70 and 72A (70A is shown in FIG. 6) extending toward the tail along the length direction of the body portion 14. The small part 68 is fixed to the first swing arm 60 by fitting the short axis of the first swing arm 60 on the permanent magnet 68 side into the small diameter hole 74 of the first swing arm.

  On the other hand, the shaft 70 on the weight 60A 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 a direction where the weight 60 </ b> B is present, 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 60 and the second swing arm 62 are crossed so that the first swing arm 60 is located on the tail side of the trunk portion 14, The short shaft 70 of the small part 68 is inserted into the elliptical groove 72 of the small flange 71 of the swing arm. The combination of the elliptical groove 72 and the short shaft 70 is 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, a swinging device comprising a combination of the first swing arm 60 and the second swing arm 62 as shown in FIG. 5 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. Each of 42 is arranged in parallel with each other on bearings 30A and 30B.

  And the above-mentioned protrusion piece 44 is exposed upward from the shaft member 42, and the nail | claw body 48 is engaged with this exposed part. The first swing arm 60 is rotatable about its own shaft member 42, and the second swing arm 62 is also rotatable about its own shaft member 42.

  As described above, the first swing arm 60 and the second swing arm 62 are configured such that the short axis 68 of the small part fixed to the first swing arm 60 is a small flange of the second swing arm 62. They are connected by connecting means formed by fitting into 71 elliptical grooves 72.

  Therefore, the driving force applied to the first swing arm 60 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 have opposite rotation directions, but are symmetrical and rotate along the virtual plane as described above at the same cycle.

  Further, due to the connection structure, the magnet 68 and the weight 60A of the first swing arm 60 and the weight 62B of the second swing arm 62 influence each other, so that the first swing arm and the second swing arm When the shaft members 42 are placed on the bearings 30A and 30B, the weight balance between the first swing arm and the second swing arm is balanced.

  Therefore, when a driving force that causes this balance to be lost is applied to one swing arm of the swinging device, the two swing arms can be rotated while interlocking even if the 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 FIG. 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 side of the body 14, can interact magnetically with the permanent magnet, and the branch arm 66 has the first swing arm 60. In order not to prevent the movement of the permanent magnet when rotating around the shaft member 42, the circular coil 58 described above has a radial direction in the direction perpendicular to the support shaft 42 of the first swing arm 60 and the main body 26. It is fixed to.

  As shown in FIG. 5, the magnet 68 and the coil 58 have their planes facing each other in parallel and are in a neutral state in which the weight balance of the two swing arms of the rocking device is balanced. Thus, when the coil and the magnet are viewed in the length direction of the body portion, the magnet 68 is positioned so that the center 68T of the magnet 68 is located above the center 58T of the coil 58 as shown in the schematic diagram of FIG. A fixed position with respect to the main body and a neutral position are set. The positional relationship between the coil 58 and the magnet 68 is set so that the center 68T of the magnet 68 is on the locus 160 of the center 58T of the magnet 68 rotating about the shaft 42.

  When the magnet 68 and the coil 58 are in such a relationship, from a neutral position taken by the pair of swing arms of the oscillating device, when a control circuit as a switch means described later excites the coil 58, the magnetic field is transferred to the permanent magnet 68. In operation, the permanent magnet 68 tends to move to a position where it overlaps the coil 58 as shown in FIG.

  At this time, when the first swing arm 60 is viewed from the side where the second swing arm 62 is located with the shaft member 42 as the center, the first swing arm 60 rotates counterclockwise. Then, the second swing arm 62 is rotated clockwise around the shaft member 42 through the connecting means described above.

  When the weight balance of the first swing arm 60 and the second swing arm 62 is balanced and both are in the neutral position, that is, when the coil 58 is not excited, the first swing arm 60 and the second swing arm 62 are fixed to the base ends of these swing arms. The pair of wing members 16 </ b> A and 16 </ b> B is in a position where the butterfly closes the wing. On the other hand, when the coil 58 is in an excited state, the positional relationship is such that a pair of protrusions (44 in FIG. 3) composed of the protrusion at the tip of the first swing arm and the protrusion at the tip of the second swing arm are separated from each other. Take the (biased position) and take the state that the butterfly has its wings open. Incidentally, FIG. 1 shows a state where butterfly wings are open.

  Since the swing of the wing member is reproduced using the above-described weight balance in the swing device, the strength of the magnetic field 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 embodiment described above, 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 configuration of the drive mechanism that drives the swing device by omitting the number of components.

  Here, the drive mechanism is composed of the solar cell 54, the circular coil 58, and a control circuit 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 oscillating device reciprocate between a neutral position in which the weight balance is achieved and an urging position displaced by a magnetic field. For returning from the latter position to the former position, the weight balance described above is used, so that 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 added to the permanent magnet 68, and both are in the biased position.

  The short shaft 70 of the small part 68 of the first swing arm 60 can move in the groove 72 of the small flange 71 of the second swing arm 62 in the process of reciprocating the swinging device between the neutral position and the biasing position. In addition, the groove 72 of the small flange has a track shape wider than the short shaft 70.

  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 as viewed obliquely, and the plane including the bearings 30A and 30B, the swinging device 40, and the drive mechanism are not shown.

  Reference numeral 100 denotes a stopper as a stopping means. FIG. 12 is a perspective view of the stopper as seen from the plane of the main body, and FIG. 13 is a perspective view of the stopper as seen from the back. As can be seen from these drawings, a thin, substantially hook-shaped piece 102 projects at a right angle from the center line portion of the rectangular plate 101. A stopper is disposed inside the bottom surface 26B of the main body so that the protruding piece 102 faces the upper surface side of the main body.

  At both ends of the stopper plate 101, there are track-like grooves 104, and small cylinders 106 that project at right angles from the inside of the bottom surface of the base are fitted into the grooves. As a result, the stopper can be advanced and retracted in the longitudinal direction of the body portion 14 while being restricted by the length of the groove 104. The rectangular plate 101 has a rectangular parallelepiped small projection 106 along the longitudinal direction on the back surface, and the small projection 106 is exposed to the outside of the base from the rectangular hole 108 on the bottom surface of the base. The user can operate the small protrusion 106 to advance and retract the stopper as described above.

  The hook-shaped projecting piece 102 has a tapered surface 110, and the stopper 100 is placed on the inside of the bottom surface of the main body 26 so that the tapered surface 110 comes to the aforementioned swinging device side. As shown in FIGS. 11 to 10, when the stopper 100 is moved to the swinging device 40 side, as shown in FIG. 14, this tapered surface 110 is the lower end of the first or second swing arm of the swinging device. Even when the electromagnetic coil 58 is excited, the swing arm is interfered with rotation.

  As a result, the swinging of the wing members 16A and 16B is suppressed. On the other hand, as shown in FIGS. 10 to 11, when the stopper 100 is separated from the swinging device 40, there is no interference between the tapered surface 110 and the swing arm, so that the swing arm is allowed to rotate. As a result, the swing of the wing member is resumed. In this embodiment, the tapered surface is in contact with the lower end of the second swing arm 62 to suppress the swing of the swing member.

  Next, a description will be given of a control circuit which is switch means and intermittently excites the electromagnetic coil 58. FIG. 15 is a block diagram of the control circuit. This control circuit intermittently supplies the current generated in the solar cell 54 (BT1 in FIG. 15) to the electromagnetic coil 58 (L1 in FIG. 15). Since the weight balance of the oscillating device is used for returning 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 the capacitor C1 is charged by a certain amount from the power source BT1, the potential of the capacitor C1 rises, the transistor Q1 is turned on, a current flows to the electromagnetic coil (L1), the coil is excited, and the excited electromagnetic The coil 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, the transistor Q1 is turned off, the current supply to the electromagnetic coil (L1) is stopped, the permanent magnet 68 is released from the biased position, and the pair of swing arms is in the neutral position described above. To return to. Thereafter, the electromagnetic coil intermittently and magnetically acts on the permanent magnet by repeated charging and discharging of the capacitor C1. Accordingly, the pair of arms can reciprocate between the neutral position and the urging position, thereby reproducing the movement of the wing member opening and closing.

A portion that is provided so as to be capable of rotating symmetrically with each other in the vertical direction with the shaft member as a rotation shaft, and a portion that is positioned below the shaft member is disposed inside the housing and is a portion that is positioned above the shaft member Is a pair of arm members arranged at least partially protruding from the housing;
Connecting means arranged to movably connect the pair of arm members to each other, and to transmit the rotational driving force supplied to one arm member to the other arm member;
A weight disposed in the housing and attached to each lower end of the pair of arm members;
A pair of wing members imitating insect wings attached to portions protruding from the housing of each of the arm members;
A branch arm member branched from any one of the pair of arm members, and arranged so that a tip end portion thereof rotates in the vertical direction;
A permanent magnet attached to the tip of the branch arm member;
An electromagnetic coil which is located at a position where it interacts magnetically with the permanent magnet, and is arranged at a distance in a range that does not hinder the movement of the permanent magnet;
A current source for supplying a current for exciting the electromagnetic coil;
Switch means for intermittently controlling the flow of current supplied to the electromagnetic coil;
With
When the coil is not excited, the pair of arm members are in a neutral position in which the weight balance is balanced with each other,
When the coil is excited, the pair of arm members rotate symmetrically with each other in the vertical direction by the rotational driving force supplied to the tip by the magnetic force acting between the excited coil and the permanent magnet. Then, when the coil is displaced from the neutral position and the excitation of the coil is released, the pair of arm members are not configured to return from the displacement position to the neutral position so that the weight balance can be obtained.
The pair of arm members reciprocate between the neutral position and the displacement position by the electromagnetic coil intermittently and magnetically acting on the permanent magnet in accordance with the operation of the switch means, A swinging toy that produces a movement of swinging wing members.
