  However, in the picture matching toy described in Patent Document 1 to Patent Document 3, when the toy is disassembled to change the top or the picture matching order is changed, the sharpened mandrel or shaft bar is exposed. Therefore, there is a problem that there is a high risk that a part of the body is hooked on the shaft rod and falls, or a part of the body such as an infant's eye is struck with the shaft rod. Further, since the mandrel and the shaft rod are fitted and fixed to the bearing, it is difficult to remove the top and the polyhedron.

  In particular, in the gear toy described in Patent Document 3 and Patent Document 4, since the shaft rod of the rotation transmitting member protrudes from the base as described above, a part of the body is hooked on the shaft rod and falls down, There is a problem that there is a high risk of sticking a part of the body such as an infant's eyes with a stick, and a dedicated base for playing is essential, and there are many on the base Since the rotation transmitting member can be attached only to any one of the holes, the gear toy can be rotated only at a limited position of the hole, and there is a problem that the degree of freedom of play becomes narrow.

  Therefore, the present invention provides a gear toy using a rotating shaft member that does not require a shaft rod and a shaft hole, and can freely and safely attach and detach a rotated body anywhere on a magnetizable surface. The task was to do.

In order to solve the above problems, the present invention is configured as follows. In other words, the gear toy of claim 1 according to the present invention includes a plurality of gear main body meshing with each other physician, respectively provided on the rotation center of the plurality of gear main body, it is magnetically attached available magnetic material in the magnet A gear toy comprising a rotating shaft member that is magnetically attached to a magnetically attachable surface and capable of rotating the gear body, wherein the rotating shaft member includes a body portion protruding from a surface of the gear body and the body portion Including a magnet for magnetizing the main body portion on the magnetisable surface, and magnetizing a gear main body connected to the rotary shaft member on the magnetisable surface, thereby allowing the magnetizable surface to adhere to the magnetizable surface. It is possible to determine the position of magnetic contact with which the main body comes into contact at an arbitrary position, and draw out the magnetic force with the center line perpendicular to the magnetically attachable surface at the contact position as the magnetic axis, and the gear main body Rotate with a structure that can be attached to and detached from the possible surface. The plurality of gear main bodies are configured to be movable in a direction parallel to the magnetically attachable surface when the rotary shaft member slides on the magnetically attachable surface. It is formed in a hemispherical shape and is in point contact with the magnetically attachable surface.

According to the gear toy of claim 1 according to the present invention, if magnetically attached it can surface, such as a white board, the top plate top surface side and office desk home appliances such as refrigerators, the rotating shaft member by Ma Gunetto The gear main body can be rotated by contacting and magnetically contacting the magnetizable surface. As a result, the danger caused by the shaft rod can be eliminated, and the gear body can be installed by freely selecting an arbitrary place as long as it can be magnetized, so that the gear body can be freely rotated and played. In addition, since the gear body can be exchanged by an easy attachment / detachment operation at an arbitrary position, the range of playing with various configurations of the gear body can be expanded. Furthermore, when the gear body is pushed in the direction parallel to the magnetizable surface, the rotary shaft member slides in the parallel direction on the surface that can be magnetized, so there is no injury between the fingers engaged between the gears. An infant can safely learn and play the gear rotation mechanism. Furthermore, since the main body is formed in a substantially hemispherical shape and makes point contact with the magnetically attachable surface, the gear main body can be attached to and detached from the toy main body more easily and safely.

It can also be used as an educational toy. In the above description, the rotating toy 11 is composed of the toy body 12 having three windows and the three panels 13. However, the number of the panels 13 does not have to be the same as the number of windows, and the number of the panels 13 equal to or more than the number of windows. You can play around by preparing them and replacing them. For example, a plurality of panels 13 having one hiragana written on each of the front and back surfaces of the panel 13 are prepared, and three of the panels 13 are selected and fitted into the windows of the toy main body 12, and the panel 13 is rotated. A way of playing such as displaying a certain word when stopping is also possible. In addition, a plurality of panels 13 corresponding to the number of windows are selected from the panels 13 in which numbers 0 to 99 are written on the front and back sides of the panel 13, and are pivotally supported on the toy body 12, and stopped after the rotation. At the same time, it is possible to play such as calculating the numbers displayed on the panel 13.

  Next, as an example, a rotating toy 21 that can be played by magnetizing the gear toy 22 using the rotating shaft member 1 according to the present invention will be described with reference to FIGS. FIG. 4 is a perspective view showing the structure of the gear toy 22 composed of the rotary shaft member 1 and the gear body 23, and FIG. 5 is a side view thereof.

  First, the structure of the gear toy 22 using the rotating shaft member 1 as a rotating shaft will be described. As shown in FIGS. 4 and 5, the gear toy 22 includes a gear main body 23, a main body portion 1 a that protrudes in a substantially hemispherical shape and is disposed at the center of both surfaces of the disk surface of the gear main body 23, and the main body portion. It is comprised from the rotating shaft member 1 which consists of the magnet (alpha) included in 1a. The gear body 23 is a synthetic resin foam made of urethane resin, ABS resin, olefin resin, polyester resin, or the like, or a mixture of a plurality of these, and has a cushioning safety suitable for an infant to play. The material is formed using a material or the like, but a relatively hard synthetic resin such as plastic, nonmagnetic metal, ceramic, wood, or the like may be used as the material. Further, the main body 1a of the rotating shaft member 1 is formed of a relatively hard synthetic resin, wooden or metal that is slippery with respect to the magnetizable surface, as in the first embodiment. Note that the magnet α itself may be formed in a substantially hemispherical shape so as to protrude from the surface of the disk surface, thereby forming the rotating shaft member 1. As described above, the rotary shaft member 1 may be installed on the disk portion of the flat gear main body 23 so as to protrude in a substantially hemispherical shape, but a normal shaft hole 24 (see FIG. 6) is used for a general gear body. ) Is provided, the rotary shaft member 1 as described in FIG. 6 below may be formed and installed on the gear body 23.

  FIG. 6 is a perspective view showing a state in which the rotary shaft member 1 is installed in the gear main body 23 having the shaft hole 24 at the center. The rotary shaft member 1 is housed so as to be fitted into a hollow and mushroom-shaped main body 1a made of a relatively hard synthetic resin that slides smoothly on the magnetizable surface, and the hollow portion of the main body 1a. Magnet α. The magnet α may be included in the main body 1a. The main body portion 1a formed in the mushroom shape in this way is fitted into the shaft hole 24 that opens at the center of the disk surface of the gear body 23, and the circular portion toward the shaft hole of the gear body 23 is formed. Installed from both sides of the board. That is, the cylindrical portion of the mushroom-type main body 1a has a size that can be fitted into the shaft hole 24 formed at the center of the gear main body 23 without a gap. For example, the synthetic resin foam of the gear main body 23 The cylindrical portion of the main body 1a sinks and fits while pressing the inner peripheral surface of the shaft hole 24 due to the flexibility of the body, and the cylindrical portion of the main body 1a is added by the elastic force of the inner peripheral surface of the shaft hole 24. Therefore, the rotating shaft member 1 can be fixed to the gear body 23. Further, the rotary shaft member 1 fitted in the shaft hole 24 in this manner can be easily detached from the shaft hole 24 and is detachable. At this time, the rotating shaft member 1 fitted from both sides of the disk surface opposes the magnetic poles at which the tips of the cylindrical portions attract each other, thereby further stabilizing the fixing state of the rotating shaft member 1 to the gear body 23. be able to.

  FIG. 7 is a cross-sectional view showing a state in which the gear toy 22 configured as described above is magnetically attached to the panel 13 of the rotating toy 21 according to the embodiment. The rotating toy 21 is configured by attaching or embedding a plate-like magnetic body 25 to the panel 13 in addition to the configuration of the rotating toy 11 of the reference example 1. It is attached or embedded so as not to interfere with the magnet α provided on the upper and lower surfaces and the magnet β provided on the disc portion. When the rotary shaft member 1 provided at the center of the disc surface of the gear toy 22 is magnetically attached to the magnetic body 25 of the panel 13 with respect to the plate-like magnetic body 25, the substantially hemispherical apex is the magnetic body. It is possible to rotate with the point of contact with the surface of the arbitrary position of 25, with the contact point maintaining the magnetic adhesion with the center line orthogonal to the panel 13 as the magnetic axis. As a result, the gear toy 22 can be rotated on the surface of the rotating toy 21 or the magnetic body 25, which is a magnetically attachable surface, with the rotating shaft member 1 as an axis.

  As shown in FIG. 8, by combining a plurality of gear toys 22 and magnetically attaching them to the magnetic body 25 of the panel 13, if one of the gear toys 22 is rotated, another gear toy 22 is obtained. Since the rotating toy 21 of the embodiment is provided with the plate-like magnetic body 25, it is possible to learn while playing the rotating mechanism that rotates the gear toy 22. The combination of the gear toy 22 is not limited to spur gears as shown in FIG. 8 and the like, and various gears such as a helical gear, a bevel gear, a crown gear, a spur gear, and a worm gear are combined. It can also be rotated. 7 and 8 relating to the rotating toy 21, the magnetic body 25 is embedded or stuck, and the toy body 12 is magnetically attached to the gear toy 22 with the surface of the toy body 12 as a magnetizable surface. It is also possible.

  FIG. 9 is a perspective view showing a state in which the rod body 27 is inserted into the hole 26 provided on the disc surface of the gear toy 22. A plurality of holes 26 are provided on the disk surface of the gear body 23 so as to draw a circle around a shaft hole 24 (see FIG. 6). By inserting the rod body 27 into any one of the holes 26, an infant or the like can grasp the rod body 27 by hand and the gear toy 22 can be easily rotated. It is also possible to rotate the gear toy 22. Furthermore, by providing the plurality of holes 26, the gear toy 22 can be reduced in weight, and when the gear toy 22 is rotated, the hole 26 also rotates around the shaft hole 24. It becomes easy to grasp the rotation movement. In addition, it is preferable to use the rod body 27 in consideration of safety, such as a wooden or metal core material covered with a synthetic resin foam.

  Note that the gear toy 22 is not limited to the surface of the magnetic body 25 of the panel 13 shown in FIG. 7, but as shown in FIG. If possible, any plate surface can be used in the same manner. In addition to the rotating toy 21, the gear toy 22 can be used alone to learn and play the rotating mechanism.

  As described above, according to the rotary toy 22 capable of magnetically attaching the gear toy 22 using the rotary shaft member 1 to the magnetically attachable surface of the panel 13 or the toy main body 12 to which the magnetic body 25 is attached or embedded. By combining and magnetizing a plurality of gear toys 22 on the surface of the magnetic body 25, it is possible to learn while playing the gear rotation mechanism. Further, the gear toy 22 can be used not only by being magnetically attached to the surface of the magnetic body 25 of the panel 13 but also by being able to be magnetically attached, such as a white board 28 or a blackboard, or a side surface of a home appliance. However, it can be freely magnetized, and infants can safely learn and play the gear rotation mechanism. Further, with the gear body supported by the conventional shaft rod, there is a risk of injury such as a finger being caught between the meshed gear bodies. Since the rotary shaft member 1 magnetically attached to the body 25 or the like slides outward on a surface that can be magnetically attached by pressing a pinched finger, it is safe without causing such an injury.

  In the above embodiment, the main body 1a of the rotary shaft member 1 containing the magnet α is formed in a mushroom shape, and the cylindrical portion of the main body 1a is fitted in the shaft hole 24 (see FIG. 6) of the gear main body 23. As described above, the rotating shaft member 1 formed in a substantially hemispherical shape is flattened at the center of the disk surface of the gear body 23 using, for example, an adhesive or a synthetic resin tape. The portions may be attached and formed so as to protrude in a substantially hemispherical shape from the disc surface of the gear body 23. In the present embodiment, even the mushroom-type main body 1a is formed of a relatively hard synthetic resin that is slippery with respect to the magnetically attachable surface, and is made of wood or metal. Made of made. Alternatively, the magnet α itself formed in a substantially hemispherical shape may be directly stuck on the disk surface as the rotating shaft member 1, and the mushroom-shaped magnet α itself is fitted into the shaft hole 24 as the rotating shaft member 1. Also good.

  In addition, as an application example of the embodiment of the gear toy 22, numbers 0 to 9 are arranged in a circular shape around the shaft hole 24 on the peripheral portion of one of the disk surfaces of the gear toy 22. The gear toy 22 is rotated and used as a roulette, or after a plurality of gear toys 22 with the numbers are meshed and rotated like a roulette and stopped, two gear toys 22 at the meshed positions are engaged. It is also possible to play by improving the calculation ability while playing by calculating the numbers instantly. Further, the rotary shaft member 1 is removed from the gear body 23 and connected to each shaft hole 24 of the two gear toys 22 by inserting a rod-like body as a shaft, and the gear toy 22 is used as a tire for a car toy. The rotary shaft member 1 is fitted and fixed in either the shaft hole 24 or the peripheral hole 26, and the rod body 27 is inserted into the shaft hole 24 or the peripheral hole 26 where the rotary shaft member 1 is not fixed. By rotating within a certain frame, it is possible to play as a spirograph (registered trademark).

  Next, as reference example 2, a rotating toy 31 that can be played as a roulette will be described with reference to FIG.

  FIG. 11 is a perspective view showing a rotating toy 31 that can be played as roulette. In the rotating toy 31, a base 32 is provided at the lower end of the toy body 12 of the rotating toy 11 described in the reference example 1, and a panel 33 rotated by the rotating shaft member 1 is formed in an arrow column shape. . On the base 32, numbers are enumerated in a circle corresponding to the position indicated by the arrow of the rotating panel 33. And it can play as a roulette by rotating the panel 33 formed in the shape of an arrow column and pointing to one of the numbers in which the arrows of the panel 33 are enumerated after the rotation stops. It should be noted that the arbitrary characters to be enumerated include not only numbers but also alphabet characters, katakana, hiragana or symbols / pictograms, and characters other than numbers may be enumerated according to how to play.

  As described above, the rotating toy 31 according to the reference example 2 can be played not only by matching pictures but also by playing as a roulette if a picture is written on the panel 33 as in the above reference example 1. A rich way of playing is possible. Further, if the plate-like magnetic body 25 is attached or embedded so that the gear toy 22 can be magnetically attached to the panel 33, a variety of ways of playing including the games shown in the above embodiments can be realized. Further, since the panel 33 is easily detachable from the toy main body 12 like the panel 13 of the above-described embodiment, even an infant can easily replace the arrow column-shaped panel 33 and the panel 13 on which a picture is written. Can be.

  Besides the reference example 2, it is possible to play as a single roulette toy 34 as described below without using the toy main body 12. FIG. 12 is a perspective view showing the toy roulette toy 34, which includes a disc 35, a main body 1a formed in a substantially hemispherical shape at the center of the disc 35, and a magnet α included in the main body 1a. An arrow-shaped needle 36 is rotatably supported by the rotary shaft member 1. In the roulette toy 34, numerals are written in a circular shape on the peripheral end of the disk surface of the disk 35, and after the arrow-shaped needle 36 is rotated and stopped, the direction indicated by the arrow of the needle 36 is indicated. It is generally used in a board-like game that takes some action according to a number. The disc 35 and the needle 36 are a synthetic resin foam made of urethane resin, ABS resin, olefin resin, polyester resin, or the like, or a mixture of a plurality of these, and cushioning suitable for children to play. However, a synthetic resin such as a relatively hard plastic, a non-magnetic metal, a ceramic, or wood may be used as the material. Further, the main body 1a of the rotary shaft member 1 is formed of a relatively hard synthetic resin, wooden or metal that is slippery with respect to the magnetizable surface, as in the first embodiment. The magnet α itself formed in a substantially hemispherical shape may be used as the rotating shaft member 1.

  FIG. 13 is a side view showing the roulette toy 34. The arrow-shaped needle 36 is formed in the vicinity of the center in the longitudinal direction of both the front and back surfaces of the rotary shaft member 1 including a magnet α in a substantially hemispherical main body 1a. In addition, a disc portion 37 containing a magnet β is provided at the center of the disc 35. The disk portion 37 is also made of a relatively hard synthetic resin, wooden or metal that is slippery with respect to the rotary shaft member 1 to be magnetized, and the magnet β itself is formed in a disk shape. The disk portion 37 may be used. Then, the apex of the rotary shaft member 1 makes a “point” contact with a disk portion 37 provided at the center of the disk 35 so that the center line perpendicular to the disk surface of the disk 35 can be rotated as a magnetic axis. It is magnetized. In addition, by providing the rotating shaft member 1 on both the front and back surfaces of the needle 36, magnetic bonding with the disc portion 37 is possible on either surface. In addition, the disc part 14 may be a magnetic body formed of a metal plate.

  As described above, the roulette toy 34 can safely play the rotation of the needle 36 necessary for the roulette without using the shaft hole and the shaft core by forming the rotary shaft member 1 according to the present invention on the needle 36. . In the roulette toy 34, the disk 35 is a constituent element. However, since the rotary shaft member 1 according to the present invention is formed on the needle 36, for example, the white board 28 or the like can be magnetically attached without using the disk 35. Arbitrary numbers are arranged in a circle on the surface, and the rotary shaft member 1 is magnetically attached to the center of the circle, and the needle 36 is provided on the magnetically attachable surface. Is possible.

  As described above, according to the rotating toys 11, 21, and 31 of each example and reference example using the rotating shaft member 1, the rotated body can be rotated without requiring a shaft hole and a protruding shaft rod, Infants can play safely without injury. In addition, as described in the above embodiment and reference example 2, as long as it is a magnetically adherable surface such as a whiteboard 28, a side surface of a household electrical appliance such as a refrigerator, or a top surface of an office desk, a substantially hemispherical rotating shaft member 1, the apex of the rotary shaft member 1 is in “point” contact with the magnetizable surface, and the center line of the contact “point” perpendicular to the magnetizable surface is used as a magnetic axis. And the to-be-rotated body called the needle | hook 36 becomes rotatable without requiring a shaft rod and a shaft hole. As a result, the gear toy 22 and the roulette toy 34 can eliminate the danger caused by the shaft rod, and do not require a bearing body having a shaft hole. Since it is possible to select and install the rotated body, it is possible to play by rotating the rotated body freely as compared with the one that requires the shaft rod.

  In the reference examples 1 and 2, the magnet α is included in the substantially hemispherical rotary shaft member 1 and the magnet β is included in the disk portions 14 and 37, so that both are magnetized. It is good also as a metal magnetic body. For example, the disk surfaces 14 and 37 including the magnet β may be magnetically attached to the metal-made substantially hemispherical rotation shaft member 1, and the metal plate-shaped circle may be attached to the rotation shaft member 1 including the magnet α. The plate portion may be magnetized. Also, the disk portions 14 and 37 may be formed in a substantially hemispherical shape like the rotary shaft member 1 and may be magnetized so that the vertices face each other.

  In the above-described embodiment, the configuration in which the rotating shaft member 1 including the main body 1a and the magnet α formed in the mushroom shape is fitted into the shaft hole 24 of the gear main body 23 has been described, but the same applies to the reference examples 1 and 2. In addition, the rotary shaft member 1 formed in a mushroom shape can be formed by opening recesses into which mushroom-shaped cylindrical portions can be fitted on the upper and lower surfaces of the panel 13 or both the front and back surfaces of the needle 36.

  In each of the above-described embodiments and reference examples, the rotary shaft member 1 is formed in a substantially hemispherical shape. However, the center line perpendicular to the magnetisable surface is magnetically contacted at the contact position between the rotary shaft member and the magnetisable surface. It is sufficient that a magnetic adhesion force can be obtained as the shaft core, and the shape is not limited to a substantially hemispherical shape.

  In the above-described embodiment and reference example, the rotary shaft member 1 according to the present invention has been described mainly using a toy as an example. However, the rotary shaft member 1 according to the present invention is used for applications other than toys, such as the advertisement display of the panel 13 described in the reference example 1. It is also possible to use the rotating shaft member 1 of the present invention as long as it is a rotated body that requires rotation and has a magnetizable surface.

  In addition to the above-described embodiments and reference examples, the gear toy 22 and the like can also be used as a magnet holder for office supplies. Further, the rotary shaft member 1 is removed, and the rotary shaft member 1 alone has a substantially hemispherical shape or mushroom. It can be used as a mold magnet holder.
