Description

  The present invention relates to a magnetically activated toy using a permanent magnet.

  Permanent magnets have an attractive or repulsive action, and several toy invention techniques using this have been proposed (see, for example, Patent Documents 1 and 2).

Japanese Patent Laid-Open No. 11-114236 (hereinafter referred to as “Prior Art 1”) JP 2002-126374 A (hereinafter referred to as “Prior Art 1”)

  Prior art 1 is a play tool that can be docked by rotating two spacecrafts, each of which has a spacecraft model with a magnet attached to a round bar. Prior art 2 is formed by dividing a concrete body simulating fruit into two or more, providing a magnet on the split surface so that it can be integrated on the split surface, and inserting a toy knife etc. into this split surface It is the educational toy which provided the name of the concrete body or the description on the said division | segmentation surface of the toy to divide | segment.

  However, both of the prior arts 1 and 2 are toys that use the magnet's attractive action, and at least, at first, they cannot promote the attractive action of the magnet unless an external force is applied with the help of a human hand. There has never been a toy that moves only with the force of a magnet.

  The present invention solves the above-described problems, and an object of the present invention is to provide a toy that moves by jumping only with the force of a magnet after a predetermined period of time if it is immersed in water without any hand.

In order to achieve the above object, the gist of the invention described in claim 1 is that two magnet bodies made of magnets are arranged so that N poles or S poles face each other with a water-soluble member or a hygroscopic member interposed therebetween. The magnetic force is formed by joining and integrating, and fixing one magnet body to the lower part of the toy main body and arranging the other magnet body under the magnet body so that the toy main body stands up. In the activation toy.
The gist of the invention described in claim 2 is that a magnet body made of a magnet is interposed between a water-soluble member or a hygroscopic member at a lower portion of a magnetized toy main body so that N poles or S poles face each other. The magnetically activated toy is characterized in that it is joined and integrated, and the toy body is formed so that the magnet body faces downward.
As in the first aspect of the present invention, two magnet bodies made of magnets are joined and integrated so that N poles or S poles face each other with a water-soluble member or a hygroscopic member interposed therebetween, and one magnet body is When the toy body is fixed to the lower part of the toy body and the other magnet body is arranged below the magnet body so that the toy body stands, the water-soluble member or the hygroscopic member is immersed in an aqueous solution to stand the toy body. As a result, the bonding strength of the water-soluble member or the hygroscopic member is weakened, and the two magnet bodies are separated after a lapse of a predetermined time, so that the toy body jumps due to the magnetic repulsion of both magnet bodies.
As in the second aspect of the invention, the magnet body made of magnets is joined and integrated so that the N poles or the S poles face each other with a water-soluble member or a hygroscopic member interposed between the magnetized toy main body. And when the toy body is formed to stand with the magnet body down, the water-soluble member or the hygroscopic member has a bonding strength by standing the toy body by immersing the water-soluble member or the hygroscopic member in an aqueous solution. The magnet body is separated from the toy body after a lapse of a predetermined time and becomes a magnetically activated toy in which the toy body jumps due to magnetic repulsion.

  The magnetically activated toy of the present invention can jump after a predetermined time with only the repulsive force of the magnet if it is immersed in water without any particular hand, and it is impossible to predict when or what movement will occur. The movement is intriguing and has an excellent effect as a playful toy.

Hereinafter, the magnetically activated toy according to the present invention will be described in detail.
(1) Embodiment 1
This embodiment is a magnetically activated toy as shown in FIGS. 1 to 4, FIG. 1 is a partially sectional front view of the magnetically activated toy, FIG. 2 is an explanatory perspective view showing the operation of the magnetically activated toy of FIG. 2 is a partially enlarged view, and FIG. 4 is a side view of two magnet bodies joined and integrated so that N poles or S poles face each other.

  In the magnetically activated toy, a water-soluble member 4 or a hygroscopic member 5 is interposed in the lower part 11 of the toy main body 1, and the two magnet bodies 2 are joined in a sandwich shape so that the N poles or the S poles face each other. An integrated toy. One magnet body 2 is fixed to the lower part 11 of the toy main body 1, and the other magnet body 3 is arranged below the magnet body 2 so that the toy main body 1 stands up. Then, by immersing the water-soluble member 4 or the hygroscopic member 5 in the aqueous solution 9 and standing the toy body 1, the bonding strength of the water-soluble member 4 or the hygroscopic member 5 is weakened, and two magnet bodies after a predetermined time elapses. The toy body 1 jumps by the magnetic repulsion of the two magnet bodies 2 and 3 after the separation of the magnetic bodies 2 and 3. Here, the water-soluble member 4 contains a water-soluble substance in a part or all of the water-soluble member 4, and the two water-soluble members 4 are immersed in the aqueous solution 9 to erect the toy body 1 to elapse two magnet bodies after a predetermined time has elapsed. 2 and 3 are separated and the toy main body 1 jumps due to the magnetic repulsion of the magnet bodies 2 and 3, and the toy body 1 is satisfied. The hygroscopic member 5 also includes a hygroscopic substance in a part or all of the hygroscopic member 5, and the two magnet bodies 2, 3 are formed after a predetermined time has elapsed by dipping the hygroscopic member 5 in the aqueous solution 9 and raising the toy body 1. If the toy main body 1 jumps due to the magnetic repulsion of both the magnet bodies 2 and 3, it is sufficient.

  The toy body 1 looks like a monster as shown in FIG. 1, and a recess 11b in which one of the two magnet bodies 2 and 3 enters a lower surface 11a which becomes the lower sole of each of two legs. Form. The recess 11b is formed in the lower surface 11a of each of the two legs. The shape of the toy main body 1 is not limited to a monster, and may be a shape of a popular character such as a masked rider or Ultraman, a person, an animal, or the like.

  The magnet bodies 2 and 3 are disk bodies made of magnets. In the present embodiment, the two magnet bodies 2 and 3 have the same shape. One of the magnet bodies 2 is sized to fit into the recess 11b. By applying an adhesive to the magnet body 2 and fitting into the recess 11b, the magnet body 2 is fixed to the lower portion 11 of the toy body. Thus, the lower surface 11a of the toy body 1 and the lower surface of the magnet body 2 are flush with each other (see FIG. 3). The toy body 1 stands up as shown in FIG. 1 by joining and integrating the other magnet body 3 to the magnet body 2, but the other magnet body 3 projects from the lower surface 11 a of the toy body 1. On the opposite surface of the other magnet body 3 to the magnet body 2, onomatopoeia such as “Gya” and “Gu” from characters such as monsters formed by the toy body 1 are written.

  The external shape of the magnet bodies 2 and 3 is a disc shape which is a kind of a cylindrical shape, but can be a cylindrical shape, a disc shape, a horseshoe shape, or the like. The two magnet bodies 2 and 3 do not have to have the same shape. For example, one of the two magnet bodies 2 and 3 can be a three-dimensional product such as a cylinder, and the other can be a sheet-like body. The magnets constituting the magnet bodies 2 and 3 are solid magnets and here are ferrite magnets, but the magnets may be rare earth magnets, rare earth iron magnets, or the like. The magnets 2 and 3 are sintered magnets, but may be plastic molded products such as rare earth powder plastic magnets or rubber molded products such as rare earth powder rubber magnets.

In this magnetically activated toy, first, a magnet unit in which the two magnet bodies 2 and 3 are joined and integrated so that the N poles or the S poles face each other with the water-soluble member 4 interposed in advance is formed ( B) in FIG. Next, one magnet body 2 related to the magnet unit is fixed to the recess 11 b of the toy main body lower portion 11.
The water-soluble member 4 of the present embodiment is a water-soluble adhesive as shown in FIG. 4 (a). For example, a synthetic water-soluble adhesive such as PVA such as polyvinyl alcohol, isobutene-maleic anhydride copolymer, polyacrylamide, and polyethylene oxide. Agent is used. These synthetic water-soluble adhesives have no fire hazard. Because it does not use organic solvents, it is not toxic, and it can be touched by hand and applied to children's magnetically activated toys.
The water-soluble member 4 of the present invention is sufficient if the N poles or S poles of the two magnet bodies 2 and 3 are opposed to each other and can be joined and integrated. It does not have to have the bonding ability to join the magnet bodies 2 together. For example, as shown in FIG. 4 (b), the water-soluble member 4 may be one in which a water-insoluble adhesive 42 (or a water-insoluble adhesive) is applied and integrated on both surfaces of a water-soluble base material portion 41. The water-soluble member 4 is interposed between the two magnet bodies 2 and 3, and both the magnet bodies 2 and 3 are joined and integrated by the adhesive force of the water-insoluble adhesive 42. The water-soluble member 4 may also be one in which a double-sided tape 45 is attached and integrated on both surfaces of a water-soluble base material portion 41 as shown in FIG. Adhesive portions 45b appearing on both upper and lower surfaces of the double-sided tape 45 serve as adhesive surfaces for the upper and lower magnet bodies 2 and 3. Reference numeral 45a indicates a tape base material portion of the double-sided tape.

  Instead of the water-soluble member 4, the magnetically activated toy can be the hygroscopic member 5 provided with a hygroscopic substrate portion 51 such as an oblate or water-absorbing paper. Here, the hygroscopic member 5 includes a non-woven fabric or the like that weakens the bonding force with the magnet bodies 2 and 3 as a result of the entangled fiber structure being unraveled and deformed, for example. A sandwich-like magnet unit is formed by joining two magnet bodies 2 and 3 in advance so that the N poles or the S poles face each other with the hygroscopic member 5 interposed therebetween. The magnet body 2 is fixed to the recess 11b of the lower toy main body 11 and the other magnet body 3 is arranged below the magnet body 2 so that the toy main body 1 stands up. The hygroscopic member 5 is soaked in the aqueous solution 9 and the toy body 1 is erected, so that the two magnet bodies 2 and 3 are separated after a predetermined time and the toy body 1 jumps due to the magnetic repulsion of both the magnet bodies 2 and 3. To do so. The hygroscopic member 5 is sufficient if the N poles or the S poles of the two magnet bodies 2 and 3 are opposed to each other and can be joined and integrated, and the base material portion 51 of the hygroscopic member 5 is the magnet body. It does not have to have the adhesive ability to join two or three together. For example, as shown in FIG. 4B, the hygroscopic member 5 is formed by applying and integrating a water-insoluble adhesive 52 (or a water-insoluble adhesive) on both surfaces of the hygroscopic substrate portion 51, and It may be interposed between the two magnet bodies 2 and 3, and the magnet bodies 2 and 3 may be joined and integrated by the adhesive force of the water-insoluble adhesive 52. As shown in FIG. 4C, the hygroscopic member 5 may be one in which a double-sided tape 55 is attached and integrated on both surfaces of the hygroscopic substrate portion 51. Adhesive portions 55b appearing on both upper and lower surfaces of the tape base material portion 55a related to the double-sided tape 55 serve as an adhesive surface between the upper and lower magnet bodies 2 and 3.

(2) Embodiment 2
This embodiment is a magnetically activated toy as shown in FIG. 5, and FIG. 5 is a partially enlarged view of the toy main body lower portion 11 corresponding to FIG.
The magnetically activated toy here uses the existing toy as it is as the toy body 1 without forming the recess 11b into which the magnet body 2 is fitted in the toy body 1, and the sole lower surface 11a corresponding to the lower part 11 of the toy body 1 It is assumed that two magnet bodies 2 and 3 are provided which are joined and integrated so that the N poles or the S poles face each other with the water-soluble member 4 or the hygroscopic member 5 interposed therebetween. A magnet unit in which the two magnet bodies 2 and 3 are joined and integrated in advance through the water-soluble member 4 or the hygroscopic member 5 protrudes from the soles. Other configurations are the same as those of the first embodiment, and the description thereof is omitted.

(3) Embodiment 3
This embodiment is a magnetically activated toy as shown in FIG. 6, and FIG. 6 is a partially enlarged view of the toy main body lower portion 11 corresponding to FIG.
In this magnetically activated toy, the magnet body 2 used in the first and second embodiments is omitted by magnetizing the toy body 1. At least the lower part 11 of the toy main body 1 is magnetized, and the magnet body 3 made of a magnet is interposed between the water-soluble member 4 or the hygroscopic member 5 on the sole lower surface 11a of the toy main body 11 so that the N poles or the S poles are in contact with each other. Assume that the toy main body 1 is formed so as to be opposed and integrated, and the toy main body 1 stands up with the magnet body 3 facing down. Other configurations are the same as those of the first embodiment, and the description thereof is omitted.

(4) Embodiment 4
This embodiment is a magnetically activated toy as shown in FIG. 7, and FIG. 7 is a partially enlarged view of the toy main body lower portion 11 corresponding to FIG. The magnetically activated toy is not provided with a magnet unit on the lower surface 11a which is the lower sole of each of the two legs as in the second embodiment, but is provided with a stabilizer 7 on which the lower surfaces 11a of the two legs can be placed together. A magnet body 2 is used. Then, the magnet body 3 composed of the other stabilizing plate 7 is fixed so that the N poles or the S poles face each other with the water soluble member 4 or the hygroscopic member 5 interposed in the magnet body 2. Other configurations are the same as those of the first embodiment, and the description thereof is omitted.

When the magnetically activated toy configured as described above is immersed in an aqueous solution 9 such as water, the joining force that the water-soluble member 4 or the hygroscopic member 5 under the water surface joins the two magnet bodies 2 and 3 with water is obtained. The two magnet bodies 2 and 3 having the N poles or the S poles facing each other are separated after a lapse of a predetermined time without any change, and the toy is generated by the magnetic repulsion of both the magnet bodies 2 and 3. The main body 1 comes to jump. Other than soaking in an aqueous solution 9 such as water, the robot jumps and jumps without any human hand. A jumping motion that cannot be predicted when or what kind of movement will be intriguing. It is possible to play by predicting an unexpected movement of the magnet body 2 or by predicting the movement time. By adjusting the joining force of the magnet body 2 by the water-soluble member 4 or the hygroscopic member 5, the time zone in which the toy body 1 jumps can be set in any way.
Further, as a specific embodiment, when water is put into a swirl-type mosquito coil incense tray 80 and the water-soluble member 4 or the hygroscopic member 5 is immersed in this water to stand the magnetically activated toy as shown in FIG. In this way, a toy shaped like a monster jumps and falls after a predetermined time has passed, so it provides the taste and fun of being fallen by the power of a mosquito coil. Furthermore, if the words of monsters such as monsters that form the toy body 1 are formed on the surface of the magnet body 3 that is separated from the toy body 1 due to magnetic repulsion, the words of onomatopoeia such as “Ga” and “Gu” are written, You can see the wording, and when you read it, you will see the onomatopoeia when the monster falls down, making it even more interesting.

In addition, if the lower surface 11a of the toy main body 1 and the lower surface of the magnet body 2 are flush with each other as in the first embodiment, the magnetic adsorption tool can be used. After the two magnet bodies 2 and 3 are separated and the toy main body 1 jumps up due to the magnetic repulsion of the two magnet bodies 2 and 3, the toy main body 1 can be used as it is as a magnetic force adsorbing tool for stopping memo paper or the like in a refrigerator or the like. Can be beneficial. Moreover, unlike the conventional magnetic suction tool, the product value is high, and the toy main body 1 has an advantage that it has a certain degree of unevenness and is easy to grip.
If it is like Embodiment 2, a magnet unit can be attached to a ready-made product as it is, and this magnetic starting toy can be made. If the toy body 1 is magnetized as in the third embodiment, the structure of the magnetically activated toy is further simplified. If the magnet body 2 including the stabilizing plate 7 on which the lower surfaces 11a of the two legs can be put together as in the fourth embodiment, the stability of the toy main body 1 when standing is further increased.

By the way, the magnet unit constituting the magnetically activated toy according to the present invention can be used as a moisture detection sensor S as shown in FIG.
The moisture detection sensor S is a magnet unit in which two magnet bodies 2 and 3 made of magnets are joined and integrated so that N poles or S poles face each other with a water-soluble member 4 or a hygroscopic member 5 interposed therebetween. Is stored in a cylinder of the container V. Here, the moisture sensor S is formed by housing a magnet unit in which two disc-shaped magnet bodies 2 and 3 are joined and integrated with a water-soluble member 4 in a cylinder of a cylindrical container V slightly larger than the disc diameter. It has become. The inside of the container V is not only a space for storing the magnet unit, but as shown in FIG. 8 (b), when the moisture is sensed and the bonding force of the water-soluble member 4 or the hygroscopic member 5 is reduced, the magnet body 2 is magnetized. A space where both magnet bodies 2 and 3 can be separated by repulsion is secured.

The moisture detection sensors S _{1 to} S ₆ (S) configured in this way are installed in places where water leakage check is necessary, for example, under the sinks of households or in bathrooms, for example, to form a circuit as shown in FIG. Incorporated. When water leaks, the change in the state of the moisture sensor from FIG. 8 (a) to FIG. 8 (b) can be read as a change in electrical resistance, which can be used to quickly find the water leak point. In addition to a water leak detector, the moisture sensor S can be attached to a coastal breakwater and used as a detector when a high wave such as a tsunami comes. When the water is pushed and the water-soluble member 4 or the hygroscopic member 5 gets wet, the bonding force is reduced and the magnet body 2 is repelled by magnetic force. Due to this repulsion, the magnet bodies 2 and 3 are separated and a switch works, and this switch works to close the breakwater door. This moisture detection sensor S does not require any power source, and has a simple structure, performs a reliable operation as soon as possible, is rich in functionality of moisture detection, and is extremely useful.

  The present invention is not limited to those shown in the above-described embodiment, and various modifications can be made within the scope of the present invention depending on the purpose and application. The shape, size, material, and the like of the toy main body 1, the magnet bodies 2, 3, the water-soluble member 4, the hygroscopic member 5 and the like can be appropriately selected according to the application.
