Many toy blocks using magnets have been distributed so far. Such toy blocks have a common feature of utilizing the coupling force through magnetic force. At this time, how to connect the magnets to the toy blocks and the structure for the connection are important, but conventionally, there are many that mainly use the cap method. However, many magnet blocks utilizing such a cap system have a sawtooth structure only on the surface, and such a block has many problems in making a structure.

First of all, there is no problem when stacking magnet blocks using the cap method, but when assembled in three dimensions, it is easy to collapse even with a small shock, the structure itself is broken, and it is difficult to maintain its form for a long time There was a problem.

In addition, a magnet block having a sawtooth structure only on the surface has a low degree of completion of the composition because the corners do not match when making a composition such as a triangle, square, pentagon block, etc., so that a three-dimensional composition is completed. There was a limit.

In other words, the coupling angle cannot be adjusted precisely, and the coupling surface generated by the coupling of the blocks or the surface on which the blocks are extended is often not smooth when viewed from various angles. There was a problem that the outer surface became uneven.

FIG. 1 is an exploded perspective view of a sawtooth structure (10) according to an embodiment of the present invention. 2 shows the exterior of the external sawtooth structure (100) of the present invention, FIG. 3 shows the interior of the external sawtooth structure (100) of the present invention, and FIG. 4 shows the exterior of the internal sawtooth structure (200) of the present invention. Show. The sawtooth structure (10) of the present invention is composed of an outer sawtooth structure (100) and an inner sawtooth structure (200). An inner sawtooth portion (110) of the outer sawtooth structure is formed on at least a portion of the inner surface of the outer sawtooth structure (100), and at least a portion of the outer surface of the inner sawtooth structure (200) is formed on the outer surface. An outer sawtooth portion (210) of the inner sawtooth structure corresponding to the inner sawtooth portion (110) of the outer sawtooth structure is formed. Inside the internal sawtooth structure (200) is a magnet receiving part (230) that can receive the magnet (400) . Due to the force of the magnet received in the magnet receiving part (230), the blocks (300) to which the sawtooth structure (10) is mounted are coupled to each other.

As illustrated in FIGS. 1-5, the internal sawtooth structure (200) is mounted or coupled to the interior of the external sawtooth structure (100). Between the external sawtooth structure (100) and the internal sawtooth structure (200), a free space having a predetermined distance or more is formed. Through the clearance space, the inner sawtooth structure (200) can rotate in the outer sawtooth structure (100). If the free space is too small, the outer sawtooth (2 11 -1) of the inner sawtooth structure of the outer sawtooth portion (210) of the inner sawtooth structure will have an inner sawtooth portion (110) of the outer sawtooth structure. The saw blade of the inner saw blade (111-1) of the external saw blade structure cannot be overcome. Therefore, the internal sawtooth structure (200) is difficult to rotate, and the fine adjustment of the block coupling angle, which is the core effect of the present invention, cannot be performed. On the other hand, if the free space is too large, the internal sawtooth structure (200) will rotate freely without appropriate resistance in the external sawtooth structure (100). It becomes impossible to finely adjust a certain block coupling angle. Accordingly, while the free space prevents free rotation of the internal sawtooth structure (200), the outer sawtooth (2 1 1-1) of the internal sawtooth structure is the inner sawtooth (111-) of the external sawtooth structure. When overcoming 1), it is preferable to maintain an appropriate resistance. For this purpose, the virtual outer line connecting the sawtooth of the outer sawtooth structure (2 1 1-1) of the inner sawtooth structure is the virtual outer line connecting the sawtooth of the inner sawtooth (111-1) of the outer sawtooth structure. Is preferably greater than or equal to the radius of.

As shown in FIGS. 9 to 10, the inner sawtooth portion (110) of the outer sawtooth structure is formed along the inner surface of the outer sawtooth structure (100), and the outer sawtooth structure is formed. The inner serrated portion (110) is divided into an inner serrated region (111) in which saw teeth are formed and an inner non-sawtooth region (112) having no saw teeth. The inner non-sawtooth regions (112) of the outer sawtooth structure are preferably formed alternately with the inner sawtooth regions (111). That is, the inner sawtooth portion (110) of the external sawtooth structure may have a structure without a sawtooth next to the sawtooth. The plane area occupied by the inner non-sawtooth region (112) of the outer sawtooth structure on the inner surface is equal to or greater than a ratio set in advance from the plane area occupied by the inner sawtooth region (111) of the outer sawtooth structure on the inner surface. It is preferable to be large. The ratio is 1 or more and less than 10, preferably 1 or more and 4 or less.

As illustrated in FIG. 10, when the non-sawtooth region is larger than the sawtooth region in the inner sawtooth portion (110) of the outer sawtooth structure, the outer sawtooth portion (210) of the inner sawtooth structure is a sawtooth. The region is preferably larger than the non-sawtooth region for fine angle adjustment. That is, when there are relatively few saw blades in the inner saw blade portion (110) of the outer saw blade structure, it is preferable that the saw blade of the outer saw blade portion (210) of the inner saw blade structure is relatively large. In this case, one saw blade of the inner saw blade portion (110) of the outer saw blade structure rides over many saw blades of the outer saw blade portion (210) of the inner saw blade structure, which is advantageous for finely adjusting the angle.

Meanwhile, the outer sawtooth portion (210) of the inner sawtooth structure is formed along the outer surface of the inner sawtooth structure (200). The outer sawtooth portion (210) of the internal sawtooth structure is divided into an outer sawtooth region (2 1 1) where the sawtooth is formed and an outer non-sawtooth region (2 1 2) which does not have a sawtooth. The outer non-sawtooth regions (2 1 2) of the inner sawtooth structure (200) are preferably formed alternately with the outer sawtooth regions (2 1 1). The plane area occupied by the outer non-sawtooth region (2 1 2) of the inner sawtooth structure (200) on the inner and outer surfaces is the plane area occupied by the outer sawtooth region (2 1 1) of the inner sawtooth structure on the outer surface. It is preferably larger than a preset ratio. The ratio is 1 or more and less than 10, and preferably exceeds 1 and is 4 or less.

When there are relatively few saw teeth in the outer sawtooth portion (210) of the inner sawtooth structure, it is preferable that the sawtooth of the inner sawtooth portion (110) of the outer sawtooth structure is relatively large. In this case, one saw blade of the outer saw blade portion (210) of the inner saw blade structure overcomes the multiple saw blades of the inner saw blade portion (110) of the outer saw blade structure, which is advantageous for fine adjustment of the angle.

As illustrated in FIGS. 6 to 7, the ratio of the number of inner saw blades (110) of the outer saw blade structure to the number of saw blades of the outer saw blade (210) of the inner saw blade structure is 1: 1. And a method of 1: n or n: 1 (n is a constant of 2 or more). The n is preferably 2 or more and 4 or less. When n exceeds 4, the difference in the number of saw teeth is large, and it is difficult to finely adjust the angle.

For fine angle adjustment, it is better that the number of saw blades of both the external saw blade structure (100) and the internal saw blade structure (200) is large. For example, the number of the saw blades of the external saw blade structure (100) and the number of the saw blades of the internal saw blade structure (200) are more than the number of the saw blades of the external saw blade structure (100) and the number of saw blades of the internal saw blade structure (200). It is better that the number of saw blades is 12). FIG. 8 shows one embodiment of the present invention in which there are 24 inner saw blades (111-1) of the outer saw blade structure and 24 outer saw blades (221-1) of the inner saw blade structure, and the coupling angle can be adjusted more precisely. Examples are illustrated. However, if the number of saw teeth of the external saw structure (100) and the number of saw teeth of the internal saw structure (200) are too large, the size of the external saw structure (100) or the internal saw structure (200) is limited. Therefore, the saw blade becomes extremely small. If the saw blade is too small, there will be a difference depending on the material of the saw blade constituting the saw blade structure (10), but the wear resistance and durability of the saw blade will be reduced. Therefore, the proper selection of the number of saw blades depending on the size of the saw blade structure (10) is substantially important.

As shown in FIG. 10, when the number of the inner sawtooth portions (110) of the outer sawtooth structure is larger than the number of the outer sawtooth portions (210) of the inner sawtooth structure, the inner sawtooth structure (200). Preferably, the outer non-sawtooth region (222) is sufficiently larger than the outer sawtooth region (221). For example, it is preferable that at least two inner saw blades (111-1) of the outer saw blade structure are inserted between the outer saw blades (221-1) of the inner saw blade structure. On the other hand, when the number of outer saw teeth constituting the outer sawtooth portion (210) of the inner sawtooth structure is greater than the number of inner sawtooth portions constituting the inner sawtooth portion (110) of the outer sawtooth structure, the outer sawtooth structure The inner non-sawtooth region (112) of the outer sawtooth structure is preferably sufficiently larger than the inner sawtooth region (111) of the outer sawtooth structure. For example, it is preferable that at least two or more inner saw blades (221-1) of the inner saw blade structure are inserted between the inner saw blades (111-1) of the outer saw blade structure.

The shape of the sawtooth will be described with reference to FIGS. As shown in FIG. 11, one or more saw blades of the inner saw blade (111-1) of the outer saw blade structure or the outer saw blade (221-1) of the inner saw blade structure are left and right with the vertex at the center. May be symmetric. One or more saw blades of the inner saw blade (111-1) of the outer saw blade structure or the outer saw blade (221-1) of the inner saw blade structure may be asymmetrical about the apex. When the shape of the sawtooth is asymmetrical, rotation in the sawtooth side direction with a steep slope has a larger rotational resistance than rotation in the sawtooth side direction with a gentle slope. For example, when the shape of the inner saw blade (111-1) of the outer saw blade structure is asymmetric and the outer saw blade (221-1) of the inner saw blade structure is symmetric as shown in FIG. When the saw blade (221-1) rides over the inner saw blade (111-1) of the outer saw blade structure, the rotation resistance is relatively high when the saw blade (221-1) rides over the inner saw blade (111-1) of the outer saw blade structure having a steep inclination. Becomes larger. When the sawtooth structure (10) is mounted on the block (300), the blocks (300) and the like are coupled to each other by a magnet received in the magnet receiving portion (230) of the internal sawtooth structure (200). . In order to reduce the rotational resistance to finely adjust the clockwise coupling angle and increase the rotational resistance to finely adjust the counterclockwise coupling angle, the external sawtooth structure (100) or If there is an asymmetric saw blade in any of the internal saw blade structures (200), it is necessary to properly place such an asymmetric saw blade. On the other hand, in order to further increase the rotational resistance in one direction and further decrease the rotational resistance in the opposite direction, both the external sawtooth structure (100) and the internal sawtooth structure (200) as shown in FIG. Adopts an asymmetrical sawtooth, the sawtooth direction of the asymmetrical sawtooth of the inner sawtooth portion (110) of the outer sawtooth structure is shifted from the sawtooth direction of the asymmetrical sawtooth of the outer sawtooth portion (210) of the inner sawtooth structure, and one direction When the inner sawtooth (111-1) side of the severely inclined outer sawtooth structure rides over the outer sawtooth (221-1) side of the severely inclined inner sawtooth structure when rotating to Rotation resistance is maximized. That is, when the inner sawtooth (111-1) of the outer sawtooth structure and the outer sawtooth (221-1) of the inner sawtooth structure are asymmetrical about the apex, the inner sawtooth (111 -1) and the method in which the outer saw blades (221-1) of the internal saw blade structure are combined are combined in such a manner that the rotation resistance in one direction is minimized and the rotation resistance in the opposite direction is maximized.

It is preferable that a surface sawtooth portion (220) of the internal sawtooth structure is formed on at least a part of the outer surface of the internal sawtooth structure (200). The position where the surface sawtooth portion (220) of the internal sawtooth structure is formed may be formed on the surface of the block (300), that is, the surface in contact with the mating block (300) to be coupled. The serrations of the surface sawtooth portion (220) of the internal sawtooth structure solidify the connection with the block (300), and the portion (position to be joined, face-to-face, point-pair) to be joined when the block (300) rotates. Minimize fluctuations in point, position versus position. If the surface sawtooth portion (220) of the internal sawtooth structure is not formed and is flat and flat, when trying to rotate either of the connected blocks (300), the block (300 ) Of the internal serrated structure of the internal saw-tooth structure of 220) and the surface saw-tooth portion (220) of the internal saw-tooth structure of the mating block (300) may have different relative positions. Therefore, it is difficult to finely adjust the angle when connecting the blocks. If the surface saw-tooth part (220) of the internal saw-tooth structure is present and the surface saw-tooth parts (220) of the internal saw-tooth structure that are coupled by magnetic force are not meshed strongly with each other, the rotation as intended by the user is easy. It is difficult to finely adjust the bond angle.

On the other hand, a surface sawtooth portion (120) of the external sawtooth structure is formed on a part or more of the external surface of the external sawtooth structure (100). The surface sawtooth portion (120) of the external sawtooth structure of the sawtooth structure (10) of the block (300) is the surface sawtooth portion (120) of the external sawtooth structure of the sawtooth structure (10) of the mating block (300). And increase the binding force between them. The surface sawtooth portion (120) of the external sawtooth structure is used for face-to-face bonding between the blocks (300) on which the sawtooth structure (10) is mounted. Such a structure contributes to the sustained maintenance of the connected blocks (300). The position of the surface sawtooth portion (220) of the internal sawtooth structure may be formed on the surface of the block (300), that is, on the surface that can contact the mating block (300) to be joined. . The serrations of the surface sawtooth portion (220) of the internal sawtooth structure harden the coupling with the block (300), and when the block (300) rotates, the coupling sites (position to be coupled, face-to-face, point-to-point , Position-to-position) variation is minimized. If the surface sawtooth portion (220) of the internal sawtooth structure is not formed and is flat and flat, when trying to rotate either of the connected blocks (300), the block (300 ) External sawtooth structure surface sawtooth portion (120) and the mating block (300) external sawtooth structure surface sawtooth portion (120) of the relative position of the coupling site may be different. Therefore, it is difficult to adjust the fine angle of the connected blocks. If the surface saw-tooth part (120) of the external saw-tooth structure is provided and the surface saw-tooth parts (120) of the external saw-tooth structure are not meshed with each other, the rotation as intended by the user is not easy and fine. It is difficult to adjust the bond angle.

On the other hand, the number of inner saw teeth (111-1) of the outer sawtooth structure, the number of surface sawtooth (121-1) of the outer sawtooth structure, and the arrangement of the sawtooth may be the same or independent of each other. That is, the number of the inner saw blades (111-1) of the outer saw blade structure and the number of the surface saw blades (121-1) of the outer saw blade structure can be made the same. The inner saw blade (111-1) of the outer saw blade structure and the surface saw blade (121-1) of the outer saw blade structure are arranged in accordance with the inner saw blade (111-1) of the outer saw blade structure and the outer saw blade (121-1). The surface saw blade (121-) of the outer sawtooth structure is between the first arrangement method in which the surface sawtooth (121-1) of the sawtooth structure is arranged at the same position and the inner sawtooth (111-1) of the outer sawtooth structure. Any one of the second arrangement methods in which 1) is arranged can also be selected. On the other hand, the number of inner saw blades (111-1) of the outer saw blade structure (100) may be different from the number of surface saw blades (121-1) of the outer saw blade structure. The inner saw blade 111-1 of the outer saw blade structure 100 and the surface saw blade 121-1 of the outer saw blade structure 1211 are arranged between the inner saw blades of the outer saw blade structure 100. In some cases, the surface saw blades (121-1) of the external saw blade structure are arranged.

The number of outer saw blades (2 1 1-1) of the internal saw blade structure and the number of surface saw blades (2 2 1-1) of the internal saw blade structure and the arrangement of the saw blades are the same or independent of each other. In some cases. The number of outer saw blades (2 1 1-1) of the internal saw blade structure may be the same as the number of surface saw blades (2 2 1-1) of the inner saw blade structure. However, the area of the surface sawtooth portion (220) of the inner sawtooth structure may be smaller than the area of the outer sawtooth portion (210) of the inner sawtooth structure. In this case, it is desirable that the number of outer saw blades (2 1 1-1) of the internal saw blade structure is larger than the number of surface saw blades (2 2 1-1).

As can be seen from FIG. 1, the internal sawtooth structure (200) preferably includes an internal space in which at least one or more magnets can receive a magnet receiving part (230). The internal space must be large enough for the magnet to rotate freely.
If the free rotation of the magnet is not guaranteed, the block (300) cannot be easily coupled when the mating block (300) approaches regardless of the NS position of the mating block (300).
