Description

  The present invention relates to a magnetic toy that causes a doll placed on a pedestal to perform an action resembling walking.

Conventionally, many toys for operating a doll having a magnetic attachment placed on a pedestal following the movement of a magnet provided inside the pedestal have been filed.
Many of them have a structure in which a doll guided by a magnet moves so as to slide on a pedestal, so that the movement of the doll is not interesting.

For this reason, for example, as shown in Patent Document 1, a doll that walks like a human movement is also provided.

However, in order for the doll to behave like walking, a complicated mechanism was required in the pedestal.
Further, since a mechanism for following the doll itself is required, there is a drawback that a great restriction is imposed on the appearance design of the doll.

Utility model No. 3063128

  The problem to be solved is that a complicated mechanism is required for the pedestal and the doll in the toy that causes the doll to walk on the pedestal by magnetic force.

  The main feature of the present invention is that the magnetic attachments provided on both legs of the doll are moved forward and left alternately by a simple movement of the magnet inside the pedestal so that the doll can behave as if walking. .

According to the walking toy of the present invention, according to the first aspect of the present invention, the two magnets fixed to the magnet installation member inside the pedestal rotate in the other forward direction around the center of one of the two magnets. Since the magnetic body of each leg of the doll on the pedestal follows the repeated movement, a complicated mechanism is not required on the doll side, and the degree of freedom in the appearance design of the doll is increased.
In addition, the doll can be easily manufactured, and if a plurality of dolls are used, the doll being operated can be replaced. Therefore, there is an advantage that a more toy can be provided.
Furthermore, because of the characteristics of the magnet, the sliding force in the right-angle direction is much smaller than the attracting force to the magnetized body, so that there is an advantage that it can be operated even with a minute electric power like a solar cell.

  According to the invention of claim 2, not only the movement along the circular orbit which has been often seen in this kind of toy so far, but also the arrangement of the orbit including the straight movement is possible, so that it can be developed into various play. It becomes possible.

(Example 2) 12A, 12B, and 12C are explanatory views showing other arrangement examples of the chain and the sprocket. (Example 2)

  A magnet holding member that has two magnets on the surface in contact with the back side of the pedestal and that is pivotally supported by a shaft provided in a part of the moving lever is mounted on the inside of the pedestal by the movement of the moving lever. When the magnet holding member is moved on the track, the protrusion provided on the back side of each magnet hits the protrusion on the track member, and the magnet moves forward with the magnet holding member about the position of each magnet. As the magnet moves, the magnetized body installed near the back of both legs of the doll placed on the top of the pedestal causes the legs to alternately rotate forward with the attraction force, so that a human is walking on the doll. Remind me of an action.

  FIG. 1 is a perspective view of one embodiment of the present invention, and only the pedestal 1 is shown in cross-section for the purpose of explanation, taken along the line AA in FIG. 2 is an outer raceway plate, 3 is an inner raceway plate, 4 is a projection for a left leg fulcrum, 5 is a projection for a right leg fulcrum, 6 is a rotation lever, 26 is a secondary rotation shaft on the rotation lever 6, 7 is a magnet holding member, 10 is a doll, 8 is a magnet (two pieces) fixed to the magnet holding member 7, and 9 is a magnetized body (two pieces) installed near the back of both legs of the doll 10.

  In FIG. 1, reference numeral 12 denotes a solar cell for rotationally driving the rotary lever 6, but the power source is not limited to the solar cell 12, and any power source that can rotate the rotary lever 6, such as a dry battery, a spring, or a manual operation, is used. It is also possible to combine them. Since the main body of the present invention is the operation method of the doll, detailed description of the electronic circuit and the drive mechanism system will be omitted.

  Regarding the material of each member, at least the pedestal 1 and the doll 10, the magnet holding member 7, the outer raceway plate 2, and the inner raceway plate 3 need to be non-magnetic materials that are not affected by the magnet.

The magnetized body 9 of the doll 10 may be a metal such as iron, and is arranged with a polarity to be attracted to the magnet 8 of the magnet holding member 7 in order to further increase the attracting force. A magnet may be used.

  The structure of the magnet holding member 7 is shown in FIG. FIG. 3 is a perspective view showing the magnet holding member 7 in FIG. 1 in an inverted state. The magnet holding member 7 has a through-hole 22 in the center, and the right leg protrusion 24 and the left leg protrusion 25 and the forward direction P of the through hole 22 in the rear left and right with respect to the forward direction P of the through hole 22. An over-rotation prevention rib 23 is provided on the rear side. The two magnets 8 are fixed as shown in the figure at positions where the right leg protrusion 24 and the left leg protrusion 25 are substantially in the same position on the opposite surfaces.

  FIG. 2 shows the cross-sectional lines of FIG. 1 or FIG. 5 and represents the movement and direction on the base of the doll 10 provided as a result of the present invention. When the doll 10 moves forward by a fixed angle as indicated by an arrow 13a with the center of the right leg 15b as a central axis, the doll 10 moves next, as indicated by an arrow 14a centered around the left leg 15a. Switch to the forward rotation movement, and then repeat the forward rotation of both legs like 13b, 14b, 13c, 14c, and the whole on the base 10 in the direction indicated by the arrow 11 according to the movement of the rotary lever 6 Rotate forward.

  At this time, unlike a normal human movement, the doll 10 does not move the leg in the vertical direction, but the vertical movement is small compared to the size of the doll 10 itself. It looks as if you are walking.

  As shown in FIG. 1, the position of the magnet 8 in the pedestal is not visible from the outside, but if the doll 10 is placed on the pedestal 1 near the place where the magnet 8 passes, the magnet 8 When passing, the doll 10 automatically moves to a position where the magnetic force is most strongly applied by the attractive force of the magnet 8 and the magnetized body 9, so that the operation can be easily started.

  To make it easier to start the operation, place a mark on the base, where the magnet passes under, as a rough guide for the standing position of the doll 10, or an arrow indicating the direction of travel. It may be a point.

  FIG. 4 is an exploded perspective view illustrating main components of the first embodiment.

  The inner raceway plate 3 has a disk shape with the main rotation shaft hole 28 as the center, and has a plurality of right leg fulcrum protrusions 5 arranged at regular intervals on the outer periphery.

  The outer raceway plate 2 has a circular hole that is centered with the main rotation shaft hole 28 of the inner raceway plate 3, and has the same number of the right leg fulcrum protrusions 5 of the inner raceway plate 3 as a constant interval. The left leg fulcrum protrusion 4 is disposed with the

  The outer raceway plate 2 and the inner raceway plate 3 have an inner passage wall 29 and an outer passage wall 30, respectively, and are fixed to the base 1.

  The gear 19 is fixed to the rotary lever 6 with the main rotary shaft 20 being coaxial, and is rotated by the power from the drive mechanism C.

  The gear 19 and the rotation lever 6 may be integrally formed.

  The secondary rotation shaft 26 of the rotary lever 6 is installed at a position that is located in the horizontal middle between the outer passage wall 30 of the outer raceway plate 2 and the inner passage wall 29 of the inner raceway plate 3, and rotates the magnet holding member 7 through the through hole 22. Support it as possible.

  In the present embodiment, two secondary rotating shafts 26 of the rotating lever 6 are installed symmetrically and two magnet holding members 7 can be arranged. However, this may be a single or adjacent magnet holding member 7. More than one may be arranged as long as they do not touch each other. Nor does it need to be symmetric.

  In the present embodiment, the small motor 21, the worm gear 27 for reduction, and the reduction gear series 17 are used for the drive mechanism C. However, as long as the rotation of the rotary lever 6 can occur, manual operation, splaying, etc. Other means may be used.

  The middle plate 16, the drive mechanism C, and the bottom plate 18 for installing the drive mechanism C and other members such as a power source and a switch are fixed in the base 1.

  FIG. 5 is a cross-sectional view taken along the line BB in FIG. The solar cell 12 is omitted.

  The magnet holding member 7 is slidably mounted on a passage formed by the outer passage wall 30 of the outer raceway plate 2 and the inner passage wall 29 of the inner raceway plate 3, and the magnet holding member 7 is a driven rotary shaft 26 of the rotary lever 6. As shown in the figure, it is pivotally supported so as to rotate forward in the passage according to the rotation of the rotary lever 6.

  FIG. 6 shows the pedestal 1 for showing the rotating state of the magnet holding member 7 when the magnet holding member 7 is pivotally moved forward in the direction of arrow P supported by the driven shaft 26 of the rotary lever 6 through the through hole 22. FIG. 5 is a partial detail view showing the internal state as seen from above, excluding the position of the magnet 8 by a broken line and the shape of the back projection of the magnet holding member 7 by a solid line for explanation.

  The plurality of right leg fulcrum protrusions 5 on the inner raceway plate 3 are arranged with their positions shifted substantially in the middle of the angle between the plurality of left leg fulcrum projections 4 of the outer raceway plate 2 as shown in the figure.

  When the magnet holding member 7 comes to the position of FIG. 6A as the rotation lever 6 rotates in the direction of arrow P, a plurality of left leg protrusions 25 of the magnet holding member 7 are arranged on the outer raceway plate 2. The magnet holding member 7 starts rotating forward in the direction of the arrow Q when it hits one of the protrusions 4a for the left leg fulcrum.

  When the rotation lever 6 continues to rotate in the direction of the arrow P and reaches the position of FIG. 6B, the over-rotation prevention rib 23 hits the outer periphery of the inner raceway plate 3, and the magnet holding member 7 rotates further. If it moves forward and moves to the place where it hits the right leg fulcrum projection 5a, it starts to rotate forward in the direction of arrow R with that point as the fulcrum.

  Further, the magnet holding member 7 continues to rotate and advance in the direction of the arrow R until the rotation lever 6 continues to rotate in the direction of the arrow P and reaches the position of FIG. 6 (c). Hits the inner circumference of the outer raceway plate 2, and the magnet holding member 7 moves forward without further rotation and moves to a position where it hits the left leg fulcrum projection 4b. Toward the leg fulcrum projection 5b, the operation similar to that shown in FIG.

  The magnet 8 on the magnet holding member 7 moves as shown in FIGS. 6A, 6B and 6C in accordance with the movement of the magnet holding member 7, and the magnetized body 9 of the doll 10 is linked to this. Repeat walking action.

  In this manner, a simple mechanism having a relatively simple structure can give the doll a motion as if walking. Further, since the doll does not require a mechanism, the doll can be easily manufactured, and the doll can be easily replaced during the operation.

  The embodiment of FIG. 7 expands the range of play so that the first embodiment described above is only forward rotation on the pedestal, but can also advance straight forward, and FIG. It is decomposition | disassembly explanatory drawing which shows an element.

A chain 50 is formed as a single ring shown in FIG. 7 by connecting a plurality of sets obtained by inserting the pipe 65 of the lower chain member 50b to the shaft 51 of the upper chain member 50a. The support shaft 64 and the support shaft 66 are for pivotally supporting the through-hole 22 of the magnet holding member 7, and are also used for preventing detachment in the pedestal when the apparatus is held upside down. It is something you have.

  In FIG. 7, 10 represents a doll, 60 represents a pedestal, 7 represents a magnet holding member, and 8 represents a magnet. Of these, the doll 10 and the magnet holding member 7 may be the same as those in the first embodiment.

  The track member 52 is obtained by making the circular track of the outer track plate 2 and the inner track plate 3 in the first embodiment into an elliptical track, and has a left leg fulcrum projection 4 and a right leg fulcrum projection 5 similar to those in the first embodiment. . In the second embodiment, the outer raceway plate 2 and the inner raceway plate 3 in the first embodiment can be connected to each other at the position of the straight passage portion of the chain passage 67 to form an integral member, the raceway member 52.

  As other members, there are a drive sprocket 56 fixed to the drive gear 57, a driven sprocket 55, a drive mechanism D driven by a motor 58 having a reduction gear 59 and decelerated by an internal gear series, a battery 61, a switch 62, a bottom plate 53, and the like. Although the operation of the doll is used, the principle and the effect are the same only by changing the driving by the rotary lever 6 in the first embodiment to the driving by the chain mechanism operated by the driving sprocket 56 and the driven sprocket 55. .

  Further, as in the first embodiment, other means such as manual operation and striving may be used for driving.

  FIG. 9 is a perspective view showing the relationship between the sprocket and the chain and the outer shape of the track member 52. The magnet holding member 7 is used by being inserted into either the shaft 64 of the upper chain member 50a or the shaft 66 of the lower chain member 50b. Although FIG. 9 shows an example in which three magnet holding members 7 are used, any number of magnet holding members 7 can be arranged anywhere as long as they are not adjacent to each other.

  In FIG. 9, the sprocket and the chain are shown in an assembled state for the sake of explanation. In actual assembly, the driving sprocket 56 and the driven sprocket 55 are installed below the track member 52, and the chain is shown. 50 and the magnet holding member 7 are incorporated separately from above the track member 52.

  In the bent portion, the positions of the upper chain member 50a and the lower chain member 50b are held on the driving sprocket 56, the driven sprocket 55, the driven sprocket holding plate 54 or the upper surface of the driving mechanism D shown in FIG. .

  The relationship between the doll 10, the magnet holding member 7, the magnet 8, and the magnetized body 9 is the same as that of the first embodiment as described above.

  FIGS. 12A, 12B, and 12C are examples in which the deformation trajectory is made possible by applying the principle of the second embodiment and further adding a chain element and a sprocket element.

  As shown by way of example in FIG. 12 (c), by using a large sprocket 68, another type of deformed trajectory can be made possible.

  If Example 2 is used, it will become possible to walk and move a doll on various orbits in this way, and application to a toy having various kinds of play will be possible.

  As described above, the present invention has been described with reference to the preferred embodiments. However, the present invention is not limited to the embodiments, and various modifications can be made within the technical scope described in the claims.

  By installing a small scene on the pedestal and allowing the doll to walk in it, it can also be applied to toys with a story.

  Further, in this walking toy, the doll does not change its movement with a little force due to the attracting force of the magnet 8 and the magnetized body 9 during operation, so it is also possible to play by moving small items on the pedestal. For example, it is possible to play such as rolling a ball to a doll and carrying a dog accessory connected to the doll with a string.

  As another application example, when the dolls are shaped as a pair of battle robots and they pass each other in the form of a passage, either one of the robot's body or the weapon held by the robot touches, It can also be applied to game applications such as defeating and playing.
