<configuration>

As shown in Figs. 1 to 3, the assembly means for prefabricated toys having a rotating magnet according to a preferred embodiment of the present invention includes an inner case 100, an intermediate case 200 and a magnet ma embedded therein. , it can be made by providing an outer case (300). Here, the magnet means (M) according to the present invention may be manufactured in a polygonal shape including a cylindrical shape, a triangle, and a quadrangle, and hereinafter, a cylindrical shape will be described as an example.

First, the magnet ma may have a substantially cylindrical shape with curved edges. When the two magnets ma are attached to the shape of the magnet ma, the magnetic force generation area is widened, and it can be easily rotated in the inner case 100 .

Next, the inner case 100 is a member in which the magnet ma is embedded, and may have a substantially cylindrical shape. To explain in more detail, the inner case 100 has an open surface on the lower surface, and the upper surface has a through hole 110 in the center, a toothed part 120 machined on the edge, and a locking shaft 130 protruding symmetrically to the side surface. can be provided.

In this case, the diameter of the through hole 110 is smaller than the diameter of the magnet ma. Therefore, after the magnet ma enters through the lower surface of the inner case 100, the separation through the through hole 110 and the separation to the lower surface by the support member 320 of the outer case 300 to be described later are prevented. can In addition, the inner diameter of the inner case 100 is larger than the diameter of the magnet ma, so that when any one magnet ma comes close to the magnet ma of the other polarity, it can rotate freely and then be attracted to each other.

In addition, the toothed part 120 has two magnets attached, and when the inner case 100 is rotated after the two toothed parts 120 are attached, the toothed part 120 is alternately staggered and bitten. A rattling sound and touch can be obtained.

And the locking shaft 130 may be fitted into the locking hole 221 of the inner wall 220 of the intermediate case 200 to be described later. Accordingly, the locking shaft 130 may prevent the inner case 100 from rotating while keeping the toothed portion 120 positioned in the central hole 210 of the intermediate case 200 .

Next, the intermediate case 200 is a member in which the inner case 100 is built, and may have a substantially hollow cylindrical shape. The intermediate case 200 has a central hole 210 in the center, an inner wall 220 extending downward from the upper surface into which the inner case 100 is inserted, and an outer wall 230 spaced outward from the inner wall 220 while extending downward from the upper surface. ) may be of a double-walled structure. In this case, the length of the inner wall 220 may be shorter than the length of the outer wall 230 .

Also, the inner wall 220 may be provided with a locking hole 221 having a predetermined depth upward from the lower surface while having a predetermined interval therebetween. The locking shaft 130 of the inner case 100 inserted into the inner wall 220 may be fitted into the locking hole 221 .

In addition, guide grooves 231 of a certain length from the lower surface to the upper side at regular intervals may be machined on the outer surface of the outer wall 230 . The guide protrusion 350 of the outer case 300 to be described later may be fitted into the guide groove 231 .

In addition, the first locking projections 232 of a predetermined length in the lateral direction while being spaced apart from each other may be processed on the inner surface of the outer wall 230 . A second locking protrusion 360 , which is a hook shape of the outer case 300 , which will be described later, may be fastened to the first locking protrusion 232 .

In addition, separation holes 233 may be machined at regular intervals on the upper surface. The separation hole 233 may be positioned such that a coupling portion of the first locking protrusion 232 and the second locking protrusion 360 is exposed to the outside. Check the coupling state of the first locking projection 232 and the second locking projection 360 through the separation hole 233, and if necessary, put a coupling releasing tool into the separation hole 233 to the first locking projection 232 And it is also possible to release the hook coupling of the second locking projection (360).

And in the central hole 210, the toothed portion 120 of the inner case 100 may be located. At this time, the locking shaft 130 fitted in the locking hole 221 by a clearance between the lower surface of the inner case 100 and the support member 320 may be moved in the vertical direction. Due to this, when the two magnet means (M) are attached, the toothed portion 120 can protrude as much as possible from the central hole 210 while the inner case 100 moves. When the inner case 100 rotates due to the protrusion of the toothed portion 120 , the sound and touch generated between the toothed portions 120 attached to each other can be maximized.

Finally, the outer case 300 is a member in which the intermediate case 200 is built, and may have a substantially hollow cylindrical shape. At this time, the upper portion of the outer case 300 is provided with a flange 310 whose upper end is bent outwardly while the upper surface is opened, and the lower portion is processed inwardly by one-stage or multi-stage stepwise deflection so that the lower surface can be opened.

In addition, the outer case 300 may include a support member 320 , a support member 330 , an auxiliary support member 340 , a guide protrusion 350 , and a second locking protrusion 360 .

Here, the support member 320 may have a substantially rectangular plate shape. The supporting member 320 may be disposed across a hole in the central portion of the open lower surface of the outer case 300 . At this time, the inner case 100 , the intermediate case 200 and the outer case 300 may block the open lower surface of the inner case 100 in the assembled magnet means (M). Accordingly, the magnet ma in the inner case 100 may be prevented from escaping by the support member 320 . Here, the position of the upper end of the support member 320 is such that the vertical movement of the locking shaft 130 fitted in the locking hole 221 is possible, which causes the inner case 100 to move up and down within the intermediate case 200 by several mm. can be moved to the extent that

In addition, the support member 330 may be positioned at both ends of the support member 320 to protrude downward from the lower surface. At this time, the lower portion of the support member 320 is fixed to the support member 330 , and the lower end of the support member 320 may be positioned higher than the lower end of the support member 330 .

Also, the auxiliary support member 340 may protrude downward from the lower surface between the support members 330 .
The reason for the above is that when combined with the body (B) of the toy block (T) as in FIGS. 1 to 3 as well as in FIG. 4, the toy block (T) protrudes downward to the lower part of the body to act as four coupling pins, thereby improving the bonding force with the toy block. .
That is, this block toy is a toy that tastes like a hand by applying rotation after coupling, and if there is no auxiliary support member 340 and support member 330 in the body (B) coupled in the toy block (T), there is no coupling adhesive force or If it is lowered, it can be predicted that the body (B) rotates without jamming in the toy block (T) during the coupling rotation between the blocks and there is no coupling force. Therefore, it is self-evident that the auxiliary support member 340 and the support member 330 in the body (B) will improve the coupling force between the toy block (T) and the body (B).

In addition, the guide protrusion 350 may protrude inwardly at a predetermined interval and a predetermined height along the circumference of the inner surface. The guide protrusion 350 is fitted into the guide groove 231 of the intermediate case 200 . Therefore, rotation in the circumferential direction in the state in which the intermediate case 200 is fastened to the outer case 300 can be prevented. Here, the outer case 300 may further include an auxiliary hole 370 formed in a portion where the guide protrusion 350 is processed while being a bent portion of the lower portion.

And the second locking protrusion 360 is disposed between the guide protrusions 350, is spaced apart from the inner surface and has a certain height upward, and a hook shape may be formed thereon. The second locking projection 360 may be fastened to the first locking projection 232 of the intermediate case 200 .

Here, for the coupling of the guide protrusion 350 and the guide groove 231 and the fastening of the second locking protrusion 360 and the first locking protrusion 232 , the inner wall 220 is the guide protrusion 350 and the second locking protrusion. 360 may be sandwiched.

On the other hand, referring to FIG. 4 is a cross-sectional view of the toy block (T) in which the above-described magnet means (M) is fixed to the body (B).

The inner case 100, the intermediate case 200, and the outer case 300 are coupled to the magnet means (M) is inserted into the body (B) can be fixed by adhesive. At this time, the flange 310 of the upper end of the outer case 300 may slightly protrude to the outside, and in addition, the upper surface of the flange 310 may be positioned flat with the upper surface of the body B or may be arranged to slightly enter. At this time, the flange 310 can adjust the height of the magnet means (M) inserted into the body (B).

In addition, the body (B) may be made of a material with a cushion that is harmless even if a child puts it in his/her mouth or bites it, and sits on it or pricks it safely.

As described above, those skilled in the art to which the present invention pertains will be able to understand that the present invention may be implemented in other specific forms without changing the technical spirit or essential features thereof. Therefore, it should be understood that the above-described embodiments are illustrative in all respects and not restrictive. The scope of the present invention is indicated by the claims described later rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and equivalent concepts should be interpreted as being included in the scope of the present invention. do.
