Description

[Detailed Description of the Invention] <Industrial field of application> The present invention relates to a chain-shaped magnetic decorative play equipment using magnetism.

<Prior Art> Conventionally, magnet-applied ornaments and play equipment in which a large number of small magnetic particles or strips are placed on a case containing a magnet to construct a three-dimensional pattern in a magnetic field are known. However, in each case, one magnet is used, or two magnets are arranged at appropriate intervals (Japanese Utility Model Publication No. 52-56320).

<Problems to be solved by the invention> However, in the case of conventional magnet-applied ornaments and play equipment,
There are various problems as a play equipment because there is a danger that small pieces or strips of magnetic material that stick out of the magnetic field will be scattered during hand play, or there will be a risk of injuring a young child during hand play or getting in his mouth. It was

When a single magnet is used, the magnetic force is generated from only one point, so the magnetic field range is narrow. When modeling in the horizontal direction, the magnetic force has a limit to support the weight of the magnetic strip, and it was impossible to construct a three-dimensional pattern rich in variation.

Furthermore, when using two magnets and arranging them in different pole directions, it is necessary to fix them in a container to prevent mutual attraction of the magnets, or to arrange them at appropriate intervals using spacers as in the conventional example. However, the magnetic force points from both magnets are limited to a constant or extremely narrow range, and the three-dimensional pattern constructed on it is naturally limited. Also, when two magnets are arranged in the same pole direction, the magnetic lines of force of both magnets repel each other and face outward, so conventional magnetic strips, etc., just stand up and are rich in variation. However, it was impossible to build a three-dimensional pattern.

<Means for Solving Problems> The inventor of the present invention intends to solve all the problems of the above-mentioned conventional magnet-applied ornaments and playground equipment, and a magnetic generator and a magnetic body mounted on the generator. The present invention has been reached after intensive studies on both cases.

First of all, in order to overcome the problems of the conventional magnetic pieces and strips, a closed magnetic chain made of a magnetic material and having a plurality of rings each having a bearing tube on one side is hingedly connected one after another. Used as a body.

Next, with respect to the magnetism generating table, usually two magnets, preferably three magnets or more, are arranged in the container so as to be movable mainly in the same polar directions. As a result, as many magnetic force points as can be exerted on the magnetic chain on the generating table are secured, and the magnet is moved according to the movement of the magnetic chain or the change in the shape, so that the strongest magnetic force is exerted on the chain. It was possible to make the point act constantly. As described above, even if a plurality of magnets are arranged in the same pole direction, since the magnetic body placed on the container is in a chain shape, there is no accident such as dissipation like the conventional strip-shaped magnetic body. Absent. In addition, since the magnetic chain has a closed shape in which a large number of rings of magnetic materials are pivotally connected by a shaft and a bearing tube, the modeled body that was constructed originally has some form due to the frictional force between the shaft and the bearing tube. I was keeping. Moreover, although weak, a magnetic force due to the homopolar arrangement is added and the frictional force is further enhanced, the shaft and the bearing tube are attracted to each other, and the chain structure built on the table is effective even with the homopolar arrangement of multiple magnets. It can be stored by adsorption.

In the case of the chain-shaped magnetic decorative play equipment of the present invention composed of a magnetic chain and a magnetic generation table, the problems that the conventional magnet-applied ornament and the play equipment have have been overcome, and the above-mentioned conventional magnetic play equipment. Compared with, a completely different shaped object can be freely constructed in a three-dimensional space, and the constructed object can be adsorbed and stored by magnetic force.

<Embodiment> The present invention will be described below with reference to FIGS.

The magnetic chain 1 constituting the present invention is formed by any of the following methods.

A magnetic material having an appropriate elasticity, for example, a steel wire is used to form the entire magnetic chain 1, and a similar wire and hollow pipe are used to form the chain 1.

In the former case, as shown in FIG. 3, one of the spiral coil springs 2 having long straight portions at both ends is bent at an appropriate angle of 90 ° or less to form a long side 3, and an extension portion thereof is formed. Is bent at an appropriate angle of 90 ° or less to form the long side shaft 4, and the other end of the spring 2 is bent to 90 ° to form the short side 5
And further bend at 90 ° to form the short side axis 6 to form a three-dimensional quadrilateral ring A. In this case, both the long and short shafts 4 and 6 extend substantially in the same line in opposite directions, and the length thereof is shorter than that of the spring 2. Next, a solid quadrilateral ring B having a mirror image of the ring A is manufactured. That is, as in the case of the ring A, both ends of the spiral coil spring 2'are extended to form a long side 3'and its long side axis 4 ', a short side 5'and a short side axis 6', respectively. .

In the latter case, a wire similar to the above is passed through the hollow pipes 22 and 22 'made of a magnetic material to extend the long straight portions from both ends of the pipe, and the long side, the long side axis and the short side, the short side axis are similarly set. Forming, the three-dimensional quadrilateral ring A and ring B are manufactured. (Examples formed into a magnetic chain are shown in FIGS. 6 to 7.) Hereinafter, a magnetic chain can be formed in almost the same manner by using a ring produced by any of the above methods and, unless otherwise specified. Ring A and Ring B produced by the method
Will be described.

The obtained ring A and ring B are, for example, the short side axis 6 of ring A.
Is inserted into the spring 2'of the adjacent ring B from the short side short side thereof, and the long side shaft 4 of the ring A is also inserted into the spring 2'from the long side side end thereof. , The spring 2'is used as a bearing tube to be pivotally connected in a hinged manner.
Next, the ring B connected to the ring A has a major axis 4'of the ring B,
By inserting 6'into the long and short sides of the coil springs 2 of the adjacent new ring A, the new ring A is rotatably connected. Further, the connected ring A is connected to the adjacent new ring B, and so on.
The ring B and the ring B are alternately and pivotally connected. The number of rings to be connected must be at least 6 and must be an even number. When the last ring and the first ring are rotatably connected, the closed magnetic chain 1 is obtained. All the connecting portions of the obtained magnetic chain 1 are connected to each other in a hinged manner so as to be freely rotatable. When connecting the above, the long and short shafts 4, 6
It is preferable that 4 and 6'are tightly inserted into adjacent coil springs 2'and 2 but pivotally inserted.

The examples of FIGS. 1 and 2 show an example of the magnetic chain 1 in which six rings A and six rings B, 12 rings in total, are connected. This chain 1
Has a basic hexagonal shape. Each adjacent ring is hingedly connected to form a closed chain,
It can be transformed from one polygonal shape to another and can be flipped over freely.

In the above magnetic chain 1, the ring A and the ring B are alternately connected,
It is also possible to connect the ring A and the ring A, or the ring B and the ring B, and further insert the short side axis into the long side of the coil spring and the long side axis into the short side of the coil spring. It is also possible. The shape and modeling of the chain that can be constructed can be freely changed by changing the connecting method.

In addition, instead of the spring 2 and 2'bearing, the hollow pipe 2
If 2,22 'bearings are used, it is easier to color them, engrave them, or decorate them with pet marks, character marks, etc. to further enhance their value as playground equipment or decorations. Becomes

The magnetism generating base 7 is a container 8 made of a non-magnetic material such as plastics or aluminum, in which an arbitrary number of magnets 9 are mainly movably housed in the same pole direction.
The shape of the container 8 can be arbitrarily selected, but a disk-shaped container as shown in FIGS. 4 to 7 is usually used. The number of magnets 9 is preferably two, and particularly preferably three or more. The magnets 9 arranged in the same pole direction repel each other in the container 8 according to Coulomb's law of magnetism as shown in FIG. 5, and the magnets 9 naturally keep a certain distance. Since the magnetic chain 1 on the lid of the container 8, that is, the pedestal 81 is magnetically sensitive, the plurality of magnets 9 may have either N pole or S pole as long as they have the same pole. The strength of the magnetic force of the magnet 9 housed inside the container 8 is
The magnetic chain 1 is appropriately selected depending on its size, weight, magnetic stress, and the like. The height direction inside the container 8 is made slightly higher than the thickness of the magnet 9 so that each magnet 9 can smoothly move in parallel in the container 8, and the inner surface of the bottom portion 83 of the container 8 and the top surface (the lower surface of the pedestal 81) are Smoothed out. That is, the magnet 9 attracted to the magnetic chain 1 via the cradle 81 can be smoothly moved as the magnetic chain 1 moves or deforms. Since the magnet 9 can freely move inside the magnetic container 8, the magnet 9 immediately moves inside the container 8 according to the movement and shape of the chain 1 on the receiving base 81. Then, the strongest magnetic point in the magnetic field always acts on the side of the chain 1 and the connecting portion via the pedestal 81, and can be placed under the influence of the strong magnetic field. The reference numeral 82 indicates the side of the container.

A magnetic plate such as an iron plate having the same size as the magnet 9 can be attached to the bottom of each magnet 9 housed in the container 8 to suppress the magnetic force downward in the container and strengthen the magnetic force upward.

The magnetic poles of the plurality of magnets 9 housed in the container 8 may be arranged in mutually different directions. In this case, however, the magnets 9 are arranged to prevent the magnets from attracting each other.
It is necessary to fix it on the inner surface or prevent adsorption with a separator plate or the like. Therefore, the position of the magnetic force point acting on the magnetic chain 1 is fixed or limited to a fixed range, and the range of the magnetic field exerted on the chain 1 is limited to a narrower range as compared with the case of the same polar direction. It is also possible to use one magnet 9, but the magnetic field is further narrowed and the modeling range of the magnetic chain is extremely limited.

The magnetic chain 1 obtained as described above is used as the magnetic generation base 7
Placed on the upper edge of the cradle 81, the chain-shaped magnetic decorative play equipment of the present invention is obtained.

<Operation> At least one side of the appropriately shaped polygonal magnetic chain 1 formed as described above is placed on the receiving base 81 of the magnetic movement generating base 7 so as to be placed thereon. When a plurality of magnets 9 are movably arranged in the magnetic container 8 of the generating table 7 from the same pole direction, the magnets 9 repel each other due to the magnetic Coulomb force and maintain a certain distance, and the magnets 9 are placed on each other. Depending on the position, direction, shape, size, etc. of one side of the rectangular chain 1, each magnet 9 appropriately moves in the container 8 and instantly receives the magnetic side or the like at the magnetic force point of the strongest magnetic force. It is adsorbed and held via 81. At the same time, since a strong magnetic field is exerted on every corner of the chain extending in the three-dimensional space, the connecting portions of the rings that have been pivotally connected to the adjacent rings, for example, the long and short shafts 4 and 6 and the bearing tube 2 '. , 2, etc. are strongly attracted to each other by the action of a magnetic force, and the frictional force thereof significantly limits the mobility of the connecting portion. For this reason, the magnetic chain 1 placed on the cradle 81 is attracted and maintained or stored in the form that it is manually operated, and does not easily collapse.
Also used as a decoration.

Conventionally, when a plurality of magnets 9 are oriented in the same pole direction, the magnetic strips placed on different magnetic force points on the container 8 may repel each other to form a bridge-shaped molded body. I couldn't do it, just stand in the forest. However, in the present invention, since the chain 1 has a closed shape in which constituent rings made of a magnetic material are connected in a chain, a plurality of magnets 9 housed in the container 8 are in the same polar direction. Needless to say, a wide variety of bridge-shaped structures can be constructed.

When the magnets 9 are arranged in different polar directions,
As described above, it is needless to say that the magnetic chain can be enjoyed in various ways, although there is a drawback that the magnetic force points are fixed or limited to a narrow range by fixing or attaching a separator. In the case of a single magnet 9, the range in which modeling is possible is further limited, but it is still included in the scope of the present invention.

When the magnetic chain 1 is placed on the magnetism generating base 7 and operated with a fingertip, the connecting portion can be hingedly swung by the long and short shafts of the ring and the bearing pipe made of the hollow pipe or the spiral coil spring. It is possible to freely change the construction from a three-dimensional form to a different form, and to turn it over. Since the obtained shape is adsorbed and held by the action of magnetic force, the desired shape can be maintained and stored, and it can be utilized as an unusual ornament.

<Effects of the invention> (1) Since a plurality of magnets are housed inside the magnetic generator table (container) so that they can move in the same pole direction, the magnetic Coulomb force keeps a constant distance between the magnets. No matter which part of the chain body is placed on the table or moving on the table, the magnet quickly moves to the optimum position, and the chain body can be adsorbed and held at a strong magnetic point.

(2) The magnetic chain is a closed chain in which swivel rings are connected in a chain, and since the connecting portion is always connected by a weak frictional force, a plurality of magnetic chains are housed inside the magnetic generating table. The magnets are in the same polarity direction, and even if the magnets have a weak magnetic force, the constituent rings are strongly attracted and fixed to each other by the magnetic induction action.

(3) The present invention, which combines a magnetic generation table containing a movable magnet and a magnetic chain, is an effect as a playground equipment that allows you to freely construct your favorite model in three-dimensional space, and the modeled object It also has the effect as a decoration that can be preserved by the action of magnetism.

(4) The hollow pipe of the bearing tube can be colored, engraved, or decorated to further enhance its value as a playground equipment or decoration.

INDUSTRIAL APPLICABILITY The present invention is useful as a hand-playing toy such as stress relief between study and work, head rest, and play equipment for spending time, and it can also be used for enlightening imagination and creativity.
