The preferred embodiment of the invention

Hereinafter, illustrate in greater detail the present invention with reference to the accompanying drawings.

As illustrated in fig. 1 and 2, according to assembly toy of the present invention go up in the following areas with routine techniques be essentially identical, promptly, this toy is all formed by a plurality of parts 10a, described parts 10a has the polyhedron-shaped of band composition surface 11a, described composition surface 11a can engage with the mating surface 11b of miscellaneous part 10b, yet, it is characterized in that parts 10 are formed with magnet part 100a on its composition surface 11a, and the composition surface 11b of the magnet part 100a of parts 10a by magnetic force and miscellaneous part 10b is bonded together.

In other words, only mutually in the assembly toy of the structure of easy engagement, each composition surface of each parts 10 is formed with magnetic part 100 having that each parts 10 do not use adhesive.

Therefore, reached following effect: parts 10 magnetic force by magnet part 100 on aspect the assembling of toy easily assembles up, and when aspect the dismounting of toy, adjusting the magnetism intensity of magnetic part 100, even infant's small and weak power also can be dismantled at an easy rate, and, combined shaped and in routine techniques can be destroyed easily.

Magnetic part 100 can be arranged in any position on the composition surface 11 of parts 10, yet, for more stable connection, preferred magnet part 100 is arranged in the center of composition surface 11, because magnet part 100 magnetic force can not limit relatively rotating between both parts 10.

In addition, can put a magnet part 100 on parts 10 each composition surface, yet, preferably on each composition surface 11, form many magnetic parts 100, in order to avoid the rotation of parts 10 has to be limited or the like situation, in order to avoid the size of parts 10 is relatively too big by comparison with the size of magnet part 100.

A nearlyer step ground, only forming magnet part 100 on composition surface 11 is enough with the connection that is used for each parts 10, yet, consider the problem that the user can make the problem of the assembling shape that producer I had never expected or can be held when a plurality of parts 10 that be piled into arbitrary shape, preferred magnet part 100 is formed on all surface 11 of each polyhedron-shaped parts 10.

Do not use adhesive, such junction apparatus can be adopted by the assembly toy of any situation, hereinafter, can be referred to following situation according to assembly toy of the present invention describes, the assembly toy of planar configuration is a puzzle for example, and D structure is a Lego block toy for example.

If assembly toy of the present invention is described as planar configuration, consider above all effects, when they assemble up education for use in the infant mutually, parts 10 can demonstrate letter, numeral, symbol, chart, the perhaps flat shape of any kind of.

Fig. 3 to 5 is specific embodiment to the training of infant's letter of being used for of formula toy combined according to the invention.

If each parts 10 are to form by many shapes each other hexahedron all identical with size, alphanumeric or the like can be represented by simple mode as shown in Figure 3.

If the structure of letter becomes very complicated, for example except that linear, increased curve, and the angle between each alphabetical stroke all has when differently changing, can represent various letters very for a short time by what the size of parts 10 was done, and further, shown in Figure 4 and 5, keep a suitable size can represent various letters each other by being different from that the size of each parts 10 is done.

Can be used for carrying out aforesaid letter training according to assembly toy of the present invention, the numeral training, or the like and can carry out as calculation training as described below.

In other words, shown in Fig. 6 to 8, a structure is like this formed together by part 10c and many magnet part 100 that is predetermined the interval that has that forms on its outer surface of central authorities, and

many part part

10d and 10e form with the magnet part 100d2 that has on its two sides respectively, can link to each other with other the magnet part 100e2 of segment part 10e like this.

In a such structure, core 10c is positioned on the center and the inboard of

many segment parts

10d and 10e links to each other with the outer surface of middle body 10c to form cylinder form, the part of the segment parts in whole segment parts can assemble or dismantle simply, can guide the infant to learn conception of fraction with interest easily.

Secondly, when realizing assembly toy of the present invention with a kind of stereochemical structure form, can freely form arbitrary shape, as long as can prevent that toy can be used to develop infant's creativity like this by the caused destruction of gravity by the effect of magnet part 100.

In other words, in assembly toy unequipped independent gluing mechanism for example in the situation of the Logo toy of adhesive for example, unless do not form a stable mechanism, otherwise this assembly may be destroyed immediately, thereby existence restriction when one of formation has the structure of assembly toy parts, yet, as shown in Figures 9 and 10, because magnet part 100 is installed in the fringe region of composition surface 11 of parts 10 and the parts with this structure fit together mutually, may easily constitute the unsettled frame for movement shown in Figure 11 to 13.

For this purpose, need be arranged in the magnet part 100 of each parts 10 on the fringe region of composition surface 11 of these parts 10, rather than be arranged in its center, and, preferably on each composition surface 11 or on all surface of these parts 10, form some magnet segments 100 for the assembling of any configuration.

When having used the structure of foregoing description, just can construct as shown in figure 11 ladder shape structure without any need for adhesive or any independent adhesion mechanism, also can construct the overhang structure of extension bar from wall as shown in Figure 2, can also go out the moulding of different shape or the structure of other solid by unit architecture as shown in figure 13 with different shape.

Need not to consider that any mechanical stability restrictedly assembles any three-dimensional shape convenience is provided because this toy is given, it reaches outstanding effect aspect infant's the creativity training effectively and develop by comparison with traditional assembly toy.

And when using of the present invention structure, these parts can freely assemble or decompose, if therefore the present invention is used for generally traditional assembling structure, the kind of the shape that is formed by simple parts may be very different.

For example, as shown in figure 14, if this structure comprises a rod, two ends form rotating shaft member 10f and wheel component 10g of magnet part 100, be formed with on this wheel component magnet part 100g be used for its center on rotating shaft part 10f be bonded together, can discern wheel assembly by columniform simple components.

In addition, if to have the product of a certain shape be preprepared and this product is divided into a main element and part parts, that infant can play more creative recreation.

For example, as shown in figure 15, when product shaping is a fruit, this product comprises part parts 10h therein, and these parts have the shape of separating next piece by this overall product shape punishment; Main part 10i, being shaped as of main body decomposed the shape of rest parts behind the part parts 10h on the overall shape by this product, and the infant can play the recreation that cuts fruit and eat fruit.

When assembly toy of the present invention during just like the above-mentioned structure that is assembled into arbitrary shape, when an adult for example father and mother told a story to the infant, just can construct a character, an animal, a building, or the like, can impel the infant to concentrate one's energy on this story whereby, and develop creativity more effectively.

Simultaneously, this infant with pile up toy normally timber or plastic products that is to say can not be harmful, thereby even can not cause any danger to the infant when the infant sucks these parts yet.

Because the present invention proposes under the prerequisite of the indefinite shape that can freely assemble by the magnetic force of magnet part 100, the gravity of therefore preferred this parts 10 itself is as far as possible little by comparison with the magnetic force of this magnet 110.

Therefore, within might parts 10 be hollow and main body constitute by the light plastic goods.

Simultaneously, be configured as these each parts 10 and have polyhedron-shapedly, many composition surfaces are also arranged, the number of the composition surface that preferred therein this magnet part 100 is equipped with is many as far as possible so that form different assembling shapes.

Yet, in this structure, if the magnetic pole of the magnet part 100 of two connections differs from one another without any serious problem, if but the mutually the same problem that will have of electrode produces therein because the repulsion that between them, produces they will be by not being bonded to each other.

In other words, the attraction when if magnet part 100 is configured to impel parts 10 to be connected with each other between the composition surface, so just no problem, yet, when producer be not contemplated to and formed a certain shape by structure, the magnetic pole that a situation may occur and be exactly magnet part 100 with the special shape of product of one of identical parts 10 structure the time does not conform to each other.

In order to prevent the generation of this situation, preferably the magnet part 100a of each parts 10a so constructs, be exactly under any circumstance with respect to other part 10b magnet part 100b and produce gravitation.

Therefore, shown in Figure 16 to 33, preferred magnet part of the present invention 100 be configured in case its two magnetic pole strengths to the direction that is different from each other, and preferably include the magnet of installing in the magnet assembling dimple 120 that is formed on the parts 10 110, an anti-disengaging device 200 prevents that magnet 110 breaks away from, and allows the inner space rotation of this magnet 110 at magnet assembling dimple 120 simultaneously from this magnet assembling dimple 120.

In other words, magnet 110 is installed in the inner space of the magnet assembling dimple 120 that forms on the parts 10, though and prevent from the disengaging of magnet but allow therein to rotate freely, wherein revolving force is to be caused by the repulsion between two magnets 100 when the magnetic pole of two magnet part that are bonded to each other 100 becomes identical, and the structure that produces this gravitation of the different magnetic pole by two magnet part 100 produces automatically like this.

Under these circumstances, though allow that the anti-disengaging device 200 that the rotation of magnet 110 prevents that magnet 110 breaks away from can be by the various specific embodiment as described below realizations.

According to first specific embodiment, extremely shown in Figure 17 as Figure 16, this anti-disengaging device 200 can be by the turning cylinder 211 of the center between two magnetic poles that are installed in magnet 110, and the turning cylinder assembling dimple 212 of an outer surface of main element 113 realizes so that this turning cylinder 211 is parallel on inner surface that is installed in magnet assembling dimple 120.

The most general structure that Here it is designs usually can form this turning cylinder 211 with the center of passing magnet 110 and the two ends that are connected to this center.

Herein, magnet 110 can have different shapes, yet, consider that preferred magnet is the permanent magnet 110a of the shape of cylinder by rotating the fact that it can expand the area of the composition surface that exposes to the open air.

According to second specific embodiment, as shown in figure 18, this anti-disengaging device 200 can be realized by a pair of dimple 221 that forms on surfaces opposite to each other on the center of two magnetic poles of magnet 110, pair of rotary axes ridge 222 is formed on magnet assembling dimple 120 inner surfaces and makes it can be inserted into this in the dimple 221, and one connects the outer surface that this effective circuit to dimple 221 center each other is parallel to main element 113 simultaneously.

The above structure is opposite with first specific embodiment, and its advantage that has is only because dimple 221 is be formed in magnet 110 lip-deep.

In this case, this magnet 110 also is configured to the permanent magnet 110a of a cylindrical shape, and identical in reason wherein and first specific embodiment.

According to the 3rd specific embodiment, shown in Figure 19 to 20, this anti-disengaging device 200 can be realized by a hook-shaped ridge that prevents to break away from 231, it is formed on the opening of magnet assembling dimple 120, and it is littler than the width and the length of this magnet 110 wherein to form the internal diameter of opening by hook-shaped ridge 231.

In other words, it is littler than the opening inner diameter d 3 of magnet assembling dimple 120 that the hook-shaped ridge 231 that prevents to break away from usefulness by formation prevents that the disengaging of magnet 110 from making that it has, also than the width and the little inner diameter d 2 of length of magnet 110, and anti-avulsion is from generation because the space that wherein allows magnet 110 freely to rotate forms in hook-shaped ridge 231, when two magnet part that is bonded to each other 100 magnetic poles become identical, the structure that the different magnetic pole by two magnet part 100 produces gravitation is to form automatically.

In addition, because contacting with each other, the composition surface of preferred two magnets 110 strengthens the adhesion between the magnet 110 of two magnet assemblies 100, connecting the diameter d 1 that ridge 232 has less than the inner diameter d 2 of the opening that forms on two magnetic poles of magnet 110 is effectively, and this ridge 232 stretches out and the opening by hook-shaped projection 231 breaks away from preventing when two magnets 110 are connected to each other.

Under the sort of situation, to such an extent as to if therein magnetic pole strength to the differ from one another direction of magnetic pole of direction can change by rotation, the structure of magnet 110 is not limited to a specific type, yet preferred magnet 110 is cylindrical permanent magnet 110a so that realize a kind of being relatively easy to and stable combining with other the magnet of magnet part.

According to the 4th specific embodiment, shown in Figure 21 to 24, anti-disengaging device 200 is realized by the opening of seal cover 241 sealing magnet assembling dimples 120.

It has following structure, magnet 110 do not expose to the open air outside and also directly contact but by means of magnetic force by seal cover 231 and other combination of elements, magnet 110 can not be looked at and causes infant's mystique from appearance whereby.

Therefore, preferred seal cover 241 is thin as much as possible, and seal cover 241 can be made by any magnetic material and nonmagnetic substance.

In addition, as shown in figure 21, preferably this structure is used in the assembling dimple 242 with assembling and is formed on seal cover 241 on the fringe region of opening of magnet assembling dimple 120, thereby because seal cover 241 does not reach the shape that the outside has formed a general plane.

Herein, this magnet 110 is not limited to a special structure example as a cylindrical permanent magnet 110a, spherical permanent magnet 10b, or the like.

If use this cylindrical permanent magnet 110a, there is an advantage to be exactly and produces firm adhesion because contact area is very big when magnet links to each other, and also have a disadvantage to be that the enough inner spaces that are used to rotate have to be fixed in this magnet assembling dimple 120, if use spherical permanent magnet 110b to have opposite pluses and minuses.

Further, shown in Figure 22 to 24, magnet assembling dimple 120 and seal cover 241 near near the outer surface of these parts 10 each other monolithic molding be possible, and after to parts 10 cuttings, insert magnet 110, then by means of on parts 10, connecting the disengaging that a section prevents magnet 110.

As shown in figure 23, thereby this structure can for example be formed magnet and assembles dimple 120 in the timber parts 10 a certain zone therein of making by a kind of material by means of the cutting of the drawing lines that is predetermined along one, then this spherical magnet 110 is inserted in this magnet assembling dimple 120, realizes sticking adhesive or the like in this section at last.

Moreover, aforesaid, can not be harmful when the infant sucks with mouth even infant's toy requires to the infant, timber is the suitable material that addresses that need, yet it is exactly that it is difficult to resemble plastic products that works and obtains a shape of wanting by means of injection molding that timber has a shortcoming.

In this specific embodiment, by means of cutting and bonding, magnet 110 can be easily to be inserted in the main body, and acquisition does not have the magnet part 100 of this shortcoming of timber material thus.

Figure 22 to 24 is the specific embodiment by means of the parts with magnet part 100 10 of the structure acquisition of the above description, perspective view of Figure 22 wherein, wherein magnet part 100 is formed near the center of outer surface of parts 10, Figure 24 is a perspective view, wherein magnet part 100 be formed on these parts 10 fringe region near.

At this moment, be installed in the magnet assembling dimple 120 magnet 110 be not limited to a special structure example such as cylinder bodily form permanent magnet and divide 110a, spherical permanent magnet 110b or the like, and pluses and minuses under the individual cases as mentioned above.

According to the 5th specific embodiment, shown in Figure 25 to 33, anti-disengaging device 200 can be realized by means of the magnet mounting structure 200a that is inserted into magnet assembling dimple 120, this magnet mounting structure 200a is made up of with the annular part 201 that magnet assembling dimple 120 contacts the surface, and cover 202 has been closed the opening on circular ring part 201 tops.

In other words, above-mentioned four specific embodiment, magnet 100 directly is installed in magnet assembling dimple 120 places of parts 10, allow the rotation of magnet 110 simultaneously, prevent device that magnet 110 breaks away from be added to parts 10 from one's body, yet in the present specific embodiment, magnet 110 is assembled in the magnet assembling dimple 120 with a mounting structure 200a who makes separately.

It is the material that it can be used to infant's toy that timber has following benefit, having shortcoming equally is that it is difficult to be cut into a precise shape, provide a structure that is suitable for this realization assembly toy and uses timber as the 4th this specific embodiment of the specific embodiment, the magnet of reservation shape assembling dimple 120 is made by timber, has that the independent magnet mounting structure 200a of wedge-type shape inserts and is installed in the magnet assembling dimple 120.

In other words, as shown in figure 25, when magnet 110 is inserted in the inner space of magnet mounting structure 200a, this magnet mounting structure 200a is by beaing in the magnet assembling dimple 120 that inserts and be installed to the main body of being made by timber, even can exempt having bothered of cutting when main body is made of also timber like this.
