Description

Building toy blocks assembled themselves by magnetic force {Built-up type toy blocks assembled themselves by magnetic force}

The present invention relates to a prefabricated toy block that can be easily assembled and disassembled by being coupled between blocks by a magnet.

Among the prefabricated toys, a so-called lego red-eye toy is commercially available. The red-eye toy is a collection of a plurality of blocks formed in the same or similar shape and is a toy designed to stack the blocks to form a desired shape.

Conventional toys are typically configured to have a coupling portion of the concave-convex structure so as to couple the blocks together, and are designed to maintain the same shape in a red-eye state to form a specific shape. Blocks having a concave-convex structure are manufactured to have concave portions formed on one side thereof and convex portions formed on the other side thereof, and thus have a disadvantage in that the concave portion and the convex portions are exposed to the outer surface in the final manufactured shape, thereby decreasing the satisfaction of appearance. In order to make up for this drawback, for example, a block has been proposed in which magnets are installed on each side of blocks manufactured in a cube shape to be mutually coupled using magnetic force between magnets.

However, in the case of a magnet, only different magnetic poles are bonded to each other, and the same magnetic poles are pushed out, so that when the two blocks are bonded, the same magnetic poles are exposed to the outside, which is inconvenient. In order to solve this problem, the magnet built in the block is freely rotatable in the magnet receiving space, so that either side is rotated by mutual magnetic force even if the magnets in the joint surfaces of the two blocks are arranged to have the same magnetic pole temporarily. There is also proposed a prefabricated toy that can be bonded to each other. 1 to 4 show an example of a prefabricated toy block having such a rotating magnet, and embodiments of the prefabricated toy disclosed in Korean Patent No. 0457305 (FIGS. 25 to 28 of the same publication). ) Is shown.

As shown in FIG. 1, the prefabricated toy according to the related art forms a magnet mounting groove 120 on one surface of a cube-shaped part 10, and accommodates the magnet 110b in the magnet mounting groove 120. The open cylindrical magnet mounting hole 200a is inserted into the magnet mounting groove 120 to close the magnet mounting groove 120. The size of the magnet 110b is configured to be smaller than the size of the magnet mounting groove 120 so that the magnet 110b is freely rotatable in the magnet mounting groove 120. Accordingly, when the parts 10 are adjacent to each other, the magnetic parts of the magnets 110b are rotated by the magnetic force of the magnets 110b, so that the two parts 10 are joined.

FIG. 2 is a view showing another embodiment of the magnet mounting hole 200a shown in FIG. 1, wherein the magnet mounting hole 200a includes a cover part 202 and a circumferential part 201, and a circumferential part 201. It shows an example in which the fixing means 250 consisting of a fixing wedge portion 251 is formed at the bottom of the). When the magnet mounting hole 200a is inserted into the magnet mounting groove 120, the fixed fixing wedge portion 251 of the fixed type is press-fitted into the bottom surface of the magnet mounting groove 120, so that the magnet mounting hole 200a becomes the magnet mounting groove 120. ) Is fixed within. This prevents the magnet mounting holes 200a from being easily separated from the magnet mounting groove 200 as compared to the embodiment of FIG. 1.

3 and 4 illustrate another embodiment of the magnet mounting hole 200a shown in FIG. 1, wherein the fixing means 250 of the magnet mounting hole 200a is circumscribed together with the fixing wedge portion 251. An example of the protrusion jaw portion 252a formed in a wedge shape on the outer circumferential surface of the portion 201 is illustrated. As in the embodiment of FIG. 2, when the magnet mounting hole 200a is inserted into the magnet mounting groove 120, the fixed fixing wedge 251 is press-fitted to the bottom surface of the magnet mounting groove 120 and at the same time, the protruding jaw portion 252a. ) Is fixed to the locking groove provided on the inner wall of the magnet mounting groove 120, and thus the magnet mounting hole 200a is more firmly fixed to the magnet mounting groove 120 than the embodiment of FIG.

However, the conventional prefabricated toys as described above have the following problems.

In the embodiment of FIG. 1, the magnet mounting hole 200a may be separated from the magnet mounting groove 120, and thus, the magnet 110a is separated from the magnet mounting groove 120, thereby not exerting the function of the assembled toy. At the same time, serious problems such as inadvertently swallowing the detached magnet 110b may be caused by the infant, which is the main use layer.

In the embodiment of FIG. 2, the detachment of the magnet mounting hole 200a may be prevented to some extent, but the magnet mounting hole 200a is still detached because the fixing force of the magnet mounting hole 200a depends only on the vertical pressure input. There is a possibility. In addition, when the magnet mounting holes 200a are pressed from the outside, the magnet mounting holes 200a may be more deeply pressed into the magnet mounting grooves 120. In this case, the cover part 202 of the magnet mounting holes 200a may be pressed. Since it is recessed from the surface of the component 10 to form a stepped shape, the appearance quality of the product is degraded and gives a feeling of poor completion.

3 and 4, the separation of the magnet mounting hole 200a is more firmly prevented. However, as in the embodiment of FIG. 2, the magnet mounting portion 200a is provided with the external force by providing the magnet wedge 251. There is still the possibility of being pressed in by.

In addition, in the case of the embodiment of Figures 3 and 4 there is a fear that the appearance quality of the product is further lowered due to the protruding jaw portion 252a protruding outward of the circumference 201. That is, in order not to open a gap between the outer surface of the circumference 201 of the magnet mounting hole 200a and the inner wall surface of the magnet mounting groove 120, the outer diameter of the circumference 201 and the magnet mounting groove 120 The inner diameter should be manufactured to exactly match, so that the projection jaw portion 252a protrudes outward from the circumference 201 so that the magnet mounting hole 200a including the projection jaw portion 252a is smoothly inserted into the magnet mounting groove 120. In order to do so, the outer diameter of the periphery 201 itself of the magnet mounting hole 200a should be formed to be somewhat smaller than the inner diameter of the magnet mounting groove 120. Accordingly, a gap is opened in the state in which the magnet mounting hole 200a is inserted into and coupled to the magnet mounting groove 120, thereby deteriorating the appearance quality and giving a dirty feeling to the foreign matter.

The present invention has been made to solve the above problems, an object of the present invention, in a prefabricated toy that is configured to rotate the magnet in the magnet mounting groove, the structure of the magnet mounting tool is not easily separated from the toy body It is provided so that even if an external force is applied to the magnet mounting port is configured so that the magnet mounting port is not drawn inward, and the gap between the magnet mounting hole and the magnet mounting groove is configured so as to improve the appearance of the product.

The present invention, the main body having at least one cap receiving portion formed inwardly on the outer surface; A magnet inserted into the cap accommodation portion, the cover portion closing the cap accommodation portion and a circumference portion extending inwardly from the cap accommodation portion, the magnet being a space formed by the cover portion and the circumference portion; A cap having a receiving portion; And a magnet accommodated in the magnet receiving part and configured to have a smaller size than the magnet receiving part so as to be freely rotatable in the magnet receiving part.

Here, the end portion of the circumference portion is formed with a fixed portion protruding inward from the circumference portion, the bottom surface of the cap accommodation portion is wider than the thickness of the end region alone than the thickness of the end region including the fixing portion The insertion groove is formed to have a small width and the end region is inserted therein.

Thereby, as the end region is inserted into the insertion groove, the fixing portion is compressed by the side wall of the insertion groove to press the side wall by the elasticity of the fixing portion, thereby deviating from the cap receiving portion of the cap. Is prevented.

The fixing part may be formed by bending the end region inwardly.

The distance between the cover portion and the fixing portion is configured to be such that the cover portion is placed on the same plane as the outer surface of the main body while the cap is accommodated in the cap accommodation portion.

The circumferential portion of the cap is formed to protrude inwardly to prevent separation of the magnet contained in the magnet housing portion. The release preventing portion may be formed by bending an area of the circumference portion inwardly.

The distance between the cover portion and the separation prevention portion is configured to be equal to the distance between the outer surface and the bottom surface, so that the cover portion is placed on the same plane as the outer surface in the state that the cap is accommodated in the cap receiving portion.

A portion where the bottom surface of the cap accommodation portion is connected to the insertion groove is formed as an inclined surface for guiding when the end region is inserted into the insertion groove.

The circumference part is cut off and constitutes an open surface.

The departure preventing part may be formed by bending the circumference of an area where the open surface is formed.

According to the present invention, since the cap is fixed in a state in which the cap is inserted into the cap accommodation portion, the detachment of the cap is firmly prevented. At this time, since the fixing part is formed to protrude inwardly from the circumference of the cap, it is possible to process the outer diameter of the circumference to exactly match the inner diameter of the cap accommodation portion, whereby the clearance between the circumference and the cap accommodation portion does not occur, thereby improving the appearance of the block. Is improved and foreign substances are prevented from being caught.

Further, according to the present invention, the outer surface of the cover portion is placed on the same plane as the outer surface of the main body, and even when a strong external force is applied to the cover portion, such a state is maintained, so that the appearance quality of the product is improved and the durability is increased.

In addition, since a part of the circumference is formed in a cut shape, the assemblability of the product is improved and the clearance between the cap and the inner wall of the cap accommodation portion is more effectively prevented.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

5 is a perspective view showing the appearance of the assembled toy block according to the invention.

The prefabricated toy of the present invention is configured as one set having tens to hundreds of blocks 300 as shown in FIG. Each block 300 may be manufactured in various shapes such as, for example, a cube, a cube, a triangular pyramid, a cylinder, a truncated cone, and the like. It may consist of a set. A cap 340 is provided on an outer surface of the main body 320 of each block 300, and a magnet (not shown in FIG. 5) is installed inside the cap 340.

6 to 8 is a view showing a prefabricated toy block according to a first embodiment of the present invention, Figure 6 is a perspective view of the cap coupled to the block body, Figures 7 and 8 before and before the cap is mounted to the body It is sectional drawing which shows each after.

As shown in Figure 6 to 8, one prefabricated toy block 300 is composed of a main body 320, a cap 340 and a magnet 360.

The main body 320 may be manufactured in various shapes as described above. In the drawings, various shapes of the main body 320 are not illustrated in detail, and the main parts of the main body 320 are illustrated, but the shape of the main body 320 may be variously modified.

Each main body 320 is preferably manufactured such that the outer surface of the main body 320 has one or more flat surfaces 322 to facilitate the maintenance of the bonded state after the plurality of main bodies 320 are mutually bonded to the magnetic force. On each flat surface 322, a cap accommodation portion 324 is recessed inward. The cap accommodation portion 324 is recessed to have a substantially cylindrical shape. The shape of the cap accommodating part 324 may be variously modified in addition to the shape of the rectangular parallelepiped.

Cap 340 is formed in a cylindrical shape to match the shape of the cap receiving portion 324, the upper portion is composed of a circular cover portion 341 covering the upper opening of the cap receiving portion 324, the side of the cap It is comprised by the circumferential part 342 extended from the part 341 to the inner side direction (downward in figure) of the cap accommodation part 324. As shown in FIG. The magnet accommodating part 350, which is a space in which the magnet 360 is accommodated, is formed by the cover part 341 and the circumferential part 342.

The cover part 341 is configured to have a flat surface so that the top surface thereof is coplanar with the flat surface 322 of the main body 320. The circumferential portion 342 is manufactured so that its outer diameter w1 is the same as the inner diameter w2 of the cap accommodation portion 324 so as to exactly match the cap accommodation portion 324.

The magnet 360 is configured to have a smaller size than the magnet accommodating part 350 so as to freely rotate within the magnet accommodating part 350. The shape of the magnet 360 may be configured in various ways, such as spherical and cylindrical, but in this embodiment, the cylindrical magnet 360 in which the N pole and the S pole are laterally disposed. The cylindrical magnet 360 is rotatable in the magnet accommodating part 350 about a vertical axis of rotation in the drawing.

The lower end region 345 of the circumference 342 of the cap 340 is formed with a fixing portion 346 protruding inward from the circumference 342. Preferably, the fixing part 346 is formed by bending the lower end area 345 inwardly, and may be formed in various shapes and manners.

The bottom surface 332 of the cap accommodating portion 324 is formed with an insertion groove 334 into which the lower end region 345 of the circumferential portion 342 is inserted.Insertion groove 334 is Its width Circumference 342 It is formed to be wider than the thickness of the bottom region 345 and less than the thickness of the bottom region 345 including the fixing portion 346.  According to this, Insert groove As the lower end region 345 is inserted into the 334, the fixing portion 346 as shown in FIG. 8 is removed. Insertion Groove (334) It is compressed by the side wall to press the side wall by the elasticity of the fixing portion 346. therefore Cap 340 is Cap accommodation Departure from 324 is prevented.

The portion where the bottom surface 332 of the cap accommodation portion 324 is connected to the insertion groove 334 is an inclined surface for guiding this when the lower end region 345 of the circumference portion 342 is inserted into the insertion groove 334 ( 337).

On the other hand, the distance h3 between the lid portion 341 and the fixing portion 346 is configured to match the distance h4 between the flat surface 322 and the bottom surface of the insertion groove 334. As a result, the outer surface of the lid portion 341 is coplanar with the flat surface 322 in the state where the cap 340 is accommodated in the cap receiving portion 324.

An anti-separation part 352 for preventing separation of the magnet 360 accommodated in the magnet accommodating part 350 is protruded inwardly at an intermediate portion of the cap 340 in the vertical direction of the circumferential part 342. As shown in FIGS. 7 and 8, the separation prevention part 352 is formed such that a portion of the circumference 342 is curved inward. The magnet 360 is press-fitted into the release preventing part 352 by an external force and accommodated in the magnet receiving part 350, and the magnet 360 accommodated in the magnet receiving part 350 is caught by the release preventing part 352. It is not easy to escape.

On the other hand, the distance h1 between the cover portion 341 and the separation prevention portion 352 is configured to be equal to the distance h2 between the flat surface 322 and the bottom surface 332, so that the cap 340 is the cap accommodation portion. In the state accommodated in 324, the cover portion 341 is configured to lie on the same plane as the flat surface 322.

On the other hand, the circumferential portion 342 of the cap 340 has a portion cut out to be configured as an open surface 348. Four open surfaces 348 are formed, so that the circumferential portion 342 is substantially formed in four skirt shapes respectively extending downward from the cover portion 341.

Prefabricated toy block 300 according to the present invention having the configuration as described above has the following advantages.

-The cap 340 is fixed by the fixing portion 346 in a state where the cap 340 is inserted into the cap accommodating portion 324, so that the detachment of the cap 34 is firmly prevented.

The fixing part 346 which prevents the cap 340 from being separated is formed to protrude inwardly from the circumference 342, so that the outer diameter of the circumference 342 is precisely matched with the inner diameter of the cap accommodation part 324. It becomes possible. Therefore, the clearance between the circumference 342 and the cap accommodation portion 324 does not occur, so that the appearance of the block 300 is improved and foreign matter is prevented from being caught.

The outer surface of the cover part 341 is flat by configuring the distance h3 between the cover part 341 and the fixing part 346 to be equal to the distance h4 between the flat surface 322 and the bottom surface of the insertion groove 334. Coplanar with plane 322. In addition, unlike the conventional structure shown in FIGS. 3 and 4, the lower end of the fixing portion 346 is not inserted into the bottom of the insertion groove 334 because it is not composed of a sharp cusp. Therefore, even when an external force is applied to the cap accommodating part 324 inside the cover part 341, the cover part 341 is not recessed by press-fitting, whereby the appearance quality is enhanced and the durability of the product is increased.

By configuring the distance h1 between the cover part 341 and the separation prevention part 352 to be equal to the distance h2 between the flat surface 322 and the bottom surface 332, the cover part 341 is likewise flat. And remains coplanar with 322. At this time, even if a strong external force is applied to the cover part 341, the position of the cover part 341 is restored by the elastic force of the release preventing part 352, so that the appearance quality is improved and the durability of the product is increased.

Since part of the circumference 341 is formed to be cut out by the open surface 348, the assemblability of the product is improved and the clearance between the cap 340 and the inner wall surface of the cap accommodation portion 324 is more effectively prevented. . That is, in the conventional structure shown in FIGS. 1 to 4, since the circumference 201 is formed over the entire circumference section, there is little room for the outer diameter of the circumference 201 to shrink. Therefore, in the conventional structure, in order for the circumference 201 to be easily inserted into the magnet mounting groove 120, it is preferable to manufacture the outer diameter of the circumference 201 to be somewhat smaller than the inner diameter of the magnet mounting groove 120. A gap between the mounting holes 200a and the magnet mounting groove 120 is caused. However, according to the present invention, even if the outer diameter of the circumference portion 341 is exactly the same as or slightly larger than the inner diameter of the cap accommodation portion 324, the outer diameter of the circumference portion 341 is sufficient to allow the outer diameter to contract, so the circumference portion 341 is provided. It is possible to process parts without gaps between the cap accommodating part 324 and the circumference 341 can be easily inserted into the cap accommodating part 324. Therefore, the assemblability and appearance quality are improved and foreign matter is more effectively prevented.

The magnet 360 is not easily separated from the magnet accommodating part 350 by the escape preventing part 352. Therefore, even if the cap 340 is separated from the cap accommodating part 324, the magnet 360 is not easily separated from the cap 340, thereby preventing the magnet 360 from being lost or inadvertently swallowing the magnet 360. can do.

9 to 11 are views showing a prefabricated toy block according to a second embodiment of the present invention, which is similar to FIGS. 6 to 8, respectively. In the following embodiments, the same components as in the first embodiment described above will be denoted by the same reference numerals, and the description thereof will be omitted and only different portions will be described.

In this embodiment, the configuration of the departure preventing unit 352a is different from that in the first embodiment, and the other configuration is the same as in the first embodiment. The departure prevention part 352a is formed in a curved shape so that the radius of curvature is larger than in the first embodiment. That is, in the first embodiment, the departure prevention part 352 is formed in a form in which the circumference 342 is folded, but in this embodiment, the separation prevention part 352 is formed in a semicircular shape.

According to such a configuration, since it is easier to mold the entire cap 340 including the separation preventing part 352a into one mold, there is an additional advantage that the manufacturing cost is reduced. In addition, since the structure of the departure preventing part 352a has a larger restoring elasticity, the restoring force restored to a circular shape is reduced even when the cover part 341 of the cap 340 is pressed into the cap receiving part 324 by an external force. It becomes big. Therefore, the deterioration of the appearance quality due to the depression of the cap 340 is more effectively prevented.

12 to 14 is a view showing a prefabricated toy block according to a third embodiment of the present invention, which is similar to FIGS. 6 to 8, respectively.

In this embodiment, the configuration of the departure prevention part 352b is different from that in the first and second embodiments, and the other configuration is the same as in the first and second embodiments. As described above, the circumferential portion 342 of the cap 340 according to the present invention is configured as an open surface 348, one portion of which is open, the departure prevention portion 352b is a portion where the open surface 348 is formed Is formed by bending the circumference 342 of the inner side. That is, the cap 340 of the present embodiment does not form the departure prevention part 352b of the bent form at the time of molding, the departure prevention part of the form that is downwardly connected from the cover portion 341 in a form similar to the circumferential part 342. After the molding 352b is formed, the separation prevention part 352b is bent into the cap 340 by external force to form the separation prevention part 352b. To this end, the portion where the departure prevention part 352b is bent is preferably formed by forming a bend line in advance to facilitate bending and to prevent breakage at the same time.

According to the present embodiment as described above, since the departure prevention part 352b does not form a shape protruding inwardly from the initial molding, the product is manufactured with a mold having a lower cost than the mold for forming the inwardly protruding release prevention part 352b. This has the advantage of being possible.

While the above has been shown and described with respect to preferred embodiments and applications of the present invention, the present invention is not limited to the specific embodiments and applications described above, without departing from the gist of the invention claimed in the claims Various modifications may be made by those skilled in the art to which the invention pertains, and such modifications should not be understood individually from the technical spirit or the prospect of the present invention.
