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 polyhedron-shaped parts 10a, described polyhedron-shaped parts 10a has the polyhedron-shaped of band composition surface 11a, described composition surface 11a can engage with the composition surface 11b of other polyhedron-shaped parts 10b, yet, it is characterized in that polyhedron-shaped parts 10 is formed with magnet part 100a on its composition surface 11a, and the composition surface 11b of the magnet part 100a of polyhedron-shaped parts 10a by magnetic force and other polyhedron-shaped parts 10b is bonded together.
In other words, only mutually in the assembly toy of the structure of easy engagement, each composition surface of each polyhedron-shaped parts 10 is formed with magnetic part 100 having that each polyhedron-shaped parts 10 does not use adhesive.
Therefore, reached following effect: polyhedron-shaped 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.
In addition, can put a magnet part 100 on polyhedron-shaped parts 10 each composition surface, yet, preferably on each composition surface 11, form many magnetic parts 100, in order to avoid the rotation of polyhedron-shaped parts 10 has to be limited or the like situation, in order to avoid the size of polyhedron-shaped 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 polyhedron-shaped 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 polyhedron-shaped parts 10 that be piled into arbitrary shape, preferred magnet part 100 is formed on all surface 11 of each polyhedron-shaped 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, assembly toy 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 polyhedron-shaped parts 10 is 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 polyhedron-shaped 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 polyhedron-shaped 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 polyhedron-shaped parts 10 and the polyhedron-shaped parts with this structure fits 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 polyhedron-shaped parts 10 on the fringe region of composition surface 11 of this polyhedron-shaped parts 10, rather than be arranged in its center, and, preferably on each composition surface 11 or on all surface of this polyhedron-shaped 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 polyhedron-shaped parts 10 itself is as far as possible little by comparison with the magnetic force of this magnet 110.
Therefore, within might polyhedron-shaped parts 10 be hollow and main body constitute by the light plastic goods.
Simultaneously, be configured as this each polyhedron-shaped 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 polyhedron-shaped 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 polyhedron-shaped 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 polyhedron-shaped parts 10a so constructs, be exactly under any circumstance with respect to other polyhedron-shaped parts 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 a magnet that is formed on the polyhedron-shaped parts 10 magnet of installing in the dimple 120 110 is installed, an anti-disengaging device 200 prevents that magnet 110 breaks away from, and allows that simultaneously this magnet 110 rotates in the inner space that magnet is installed dimple 120 from this magnet installation dimple 120.
In other words, magnet 110 is installed in the inner space of the magnet installation dimple 120 that forms on the polyhedron-shaped parts 10, though and prevent from the disengaging of magnet but allow therein to rotate freely, wherein revolving force is by two magnets when the magnetic pole of two magnet part that are bonded to each other 100 becomes identical
PartRepulsion between 100 causes, 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 one is installed in that magnet is installed on the inner surface of dimple 120 the turning cylinder assembling dimple 212 of an outer surface of main element 113 realizes so that this turning cylinder 211 is parallel to.
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 installation 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.
